Description

Deck chairs and their accessory systems

technical field

The utility model relates to the technical field of seat furniture, in particular to a folding recliner and its accessory system. The leg pad mechanism of the folding recliner adopting this design can be displaced between a rest position and a use position by means of a moving mechanism. The legrest mechanism is located under the seat surface when in the rest position, and is located in front of the seat surface when the legrest mechanism is in the use position.

Background technique

Under normal use, a commonly used seat structure includes: a base fixed on the ground, a seating mechanism with a seating surface, and a seat with a cushion surface that can move relative to the seating mechanism. Leg pad mechanism. The leg rest mechanism of this design can be displaced between the rest position and the use position by means of a displacement mechanism. In the rest position, the leg rest mechanism is located below the seat surface, and in the use position, the leg rest mechanism is located in front of the seat surface.

Deck chairs as described above are available today in many different design versions.

In order to make the upholstery sufficiently large, some design versions of the deck chair have, in addition to the seating mechanism, an end piece that can be moved separately. When adopting such a design scheme, in most cases, the leg pad mechanism is designed to be able to rotate relative to the seating mechanism, and in some cases, the rotation can also be realized by means of the double connecting plate mechanism. Then, in most cases a rotatable end piece is connected to the leg rest mechanism. For example, patent specifications BE1009147A3, DE102008009234A1 and DE3718645C2 have just announced the above-mentioned design scheme or similar design schemes using the leg pad mechanism and the end piece. For the design scheme that does not adopt the end piece but only has the leg pad mechanism, it is difficult to realize that the pad surface has a large enough area. For this reason, the patent specification DE102005001877A1 proposes to adopt a kind of mechanism that can change the size of the legrest mechanism. This allows the legrest mechanism to be made smaller when switching from the use position to the rest position under the seating surface. Only in this way can it be ensured that the size of the pad surface is sufficiently large in the use position, and that the leg rest mechanism is sufficiently reduced when it is rotated to reach the rest position.

Utility model content

The task of this utility model is to further design the folding recliner adopting the above design method, so that it can realize the displacement of the leg pad mechanism between the rest position and the use position through a simple mechanical mechanism. The criteria described in the novel can also be used for deck chairs where there is little space under the seating mechanism. That is, the purpose of this utility model is to realize that the folding recliner described in the utility model has a pad surface with a size sufficiently large, without having an end piece that can be displaced oppositely next to the leg pad mechanism, and without the leg pad mechanism being designed to be of a size that can Variety.

This task is solved by the following technical solution of a deck chair.

A folding recliner, comprising: a fixed base, a seating mechanism with a seating surface, and a leg resting mechanism with a cushion surface that can move relative to the seating mechanism, wherein the leg resting mechanism passes through a moving mechanism Connected below the seating mechanism; the moving mechanism has an intermediate support rod, a set of first rotating guide rails and a set of second rotating guide rails; wherein, the intermediate support rod forms a moving pair relative to the seating mechanism through the first rotating guide rails, Wherein the first rotating guide rail has at least a first rear rotating rod between the middle support rod and the seating mechanism; the leg support mechanism forms a moving pair with respect to the middle supporting rod through the second rotating guide rail, and the second rotating guide rail has at least one The first front swivel bar is located between the middle support bar and the leg rest mechanism.

Preferably, the deck chair adopting the design of the present utility model is a cushioned sofa chair or sofa. In the case of a sofa, it may have multiple leg rest mechanisms that move independently of each other.

In the following detailed description, the concept of the vertical direction refers to a direction at an angle of 90 degrees to the ground on which the deck chair is located. The transverse direction refers to the direction of extension that runs horizontally parallel to the front edge of the seat surface. The longitudinal direction of the furniture refers to the direction forming an angle of 90 degrees with the transverse direction of the furniture and the vertical direction of the furniture. The concepts of "front" and "rear" are relative to the longitudinal direction of the furniture, that is, the perspective of the user sitting on the recliner, with the user's legs facing the front and the back facing the rear.

Furthermore, in the following description the term first use position refers to a position of the recliner in which the legrest mechanism is in its rest position. The second use state refers to the state that the leg rest mechanism is in when it is in its use position. In some embodiments of the furniture described in the present utility model, a third use state is produced. In this state, the backrest can be positioned relative to the second use state when the legrest mechanism stretches outwards to a large extent. positioned in a more horizontal position.

In the first use state, the folding recliner can be placed in a normal sitting posture, and at this time, the leg rest mechanism is folded under the seating mechanism and supported on the ground. The second state of use is also referred to as the watching gesture. Under the situation that the legrest mechanism is turned upwards, this use state can make the folding recliner be in a relatively vertical sitting posture. The third use state is designed to make the folding recliner in a flat lying posture.

The feature of the foldable recliner described in the utility model is that the leg pad mechanism can have relatively large horizontal displacement. This makes it possible to dispense with the fact that the deck chair has to perform a large swivel movement in current designs of this type. The leg rest mechanism is basically horizontal at least in the rest position and the use position, that is to say, the rest surface can rotate no more than 25° relative to the horizontal plane each time. Preferably, a legrest mechanism of this design is oriented substantially horizontally throughout the transition from the rest position to the use position. Most of the technical solutions in the existing design use the leg rest mechanism to rotate to a specific position by rotation, but due to the limitation of the height of the seat, the leg rest mechanism that can rotate vertically from the bottom of the seating mechanism can only be designed with an area smaller than the height of the seating mechanism and the leg-resting mechanism in the utility model is basically stably oriented in the horizontal direction in the aforementioned manner, without large-angle rotation, so that the folding recliner can adopt a relatively large leg-resting mechanism without The height of the seating mechanism is relatively high due to the length of the leg resting mechanism. In this way, the length of the legrest mechanism in the longitudinal direction can exceed the height of the free space in the vertical direction below the seating structure. As a result, it is not necessary to separately design an end piece that can be displaced relative to the leg pad mechanism for extending the pad surface.

In order to realize the movement of the legrest mechanism from the rest position to the use position, a movement mechanism conforming to the above-mentioned working mode is designed. This displacement mechanism has an intermediate support rod, which is designed to be rotatable on the seating mechanism or the base via a first swivel guide. During the process of switching the legrest mechanism from the use position to the rest position and from the rest position to the use position according to the setting, the base and its related parts are always kept in position relative to the ground where the recliner is located, that is, no displacement occurs. Preferably, the base is a bracket on which the legs of the deck chair are also designed. The position keeping mentioned here can also be understood as being able to rotate on the spot. Thus, the base is designed to be rotatable about a vertical axis by means of a turntable or something similar in function. Likewise, if the base can rock back and forth relative to the ground, it is considered to remain in position.

As an alternative, the middle support rod can move relative to the seating mechanism or the base along a circular track through the first rotating guide rail.

The middle support bar itself is used to fix the leg-resting mechanism, and a second rotating guide rail is designed between the middle support bar and the leg-resting mechanism for this. In this way, the displacement of the leg support mechanism relative to the seating mechanism or the base is realized through two incrementally displaced rotating guide rails. This achieves an ideal dimension so that the legrest mechanism can be displaced between its rest position and its use position.

In order to cooperate to reach the required displacement stroke of the leg-resting mechanism, these two mechanisms, that is, the first rotating guide rail between the seating mechanism or the base and the middle support rod, and the distance between the middle support rod and the leg-resting mechanism The second rotary guides, respectively, can only complete a part of the required displacement travel. Therefore, a relatively short connecting rod can be used between the intermediate support rod and the base or seating mechanism. Preferably, the length of these links between their upper and lower hinge points does not exceed 40 cm, most preferably does not exceed 30 cm.

The second rotating guide rail that makes the leg resting mechanism move relative to the middle support rod is designed in this way: the leg resting mechanism can be displaced relative to the middle support rod along a circular track under the guidance of the first front rotating rod.

The above-mentioned first and second rotating guide rails can be regarded as a kind of rotating mechanism, under its action, the intermediate support rod can move relative to the base or the seating mechanism, or the seating mechanism can move along an arc relative to the base . The arc-shaped movement can be performed as a whole by the middle support rod or the leg support mechanism, preferably also by the rotating shaft at the end of the rotating rod that can move along an arc-shaped track. Preferably, at least one rotating rod that is hinged on both sides and can be rotated is used for each rotating guide rail, so that the middle support rod or the pad leg mechanism will not cause the middle support rod or pad to The leg mechanism deflects in its entirety relative to the seating mechanism/base or relative to the intermediate support rod. That is, the orientation of the legrest mechanism relative to the middle support rod and the direction of the middle support rod relative to the seating mechanism or the base will not change, or only a small change (<25°), which is also one of the advantages of the present invention .

For this reason, the second rotary guide rail is preferably designed as a double-link rotary guide rail. This means that the second swivel rail is equipped with a first and a second front swivel rod, the first front swivel rod can revolve around the fifth swivel axis mounted on the middle support rod and the The six rotation axes rotate; the second front rotation lever can rotate around the seventh rotation axis installed on the middle support rod and the eighth rotation axis installed on the leg pad mechanism; and the fifth rotation axis and the sixth rotation axis There is a certain distance between the shafts, and there is a certain distance between the seventh rotation axis and the eighth rotation axis; so that although the leg pad mechanism can move along an arc track relative to the middle support rod, it will not deflect or only A slight deflection occurs. Instead of such a double-link rotary guide, other forms of rotary guide with positive guidance can also be used.

By designing the first and second front rotating rods to be of different lengths or bent towards each other, the upside-down size can also be affected when the leg rest mechanism moves relative to the middle support rod. When the front rotating rods are parallel to each other and have the same length, the pad surface always keeps its orientation relative to the middle support rod unchanged.

Furthermore, in terms of the connection between the intermediate support rod and the seating mechanism or the base through the first rotating guide rail, in principle, it can be designed that the intermediate support rod is fixedly connected with the first rear rotating rod of the first rotating guide rail as a whole, So that its orientation always follows the rotation movement. However, it can also be designed that on the one hand the first rear rotating rod can be rotatably hinged on the seating mechanism or the base around a second rotating shaft; Rotatably hinged on the middle support rod. This also prevents the middle support rod from rotating by the same amount as the rear rotation rod. Therefore, the middle support rod can be displaced through the first rotating guide rail while the leg rest mechanism is kept substantially facing the horizontal direction without significantly changing its orientation.

However, in order to realize the displacement of the intermediate support rod in the above-mentioned manner, the forced guiding mechanism is preferably designed so that each rotational position of the first rotating guide rail relative to the seating mechanism or the base corresponds to the resulting, intermediate support The rotational position of the rod relative to the first rotational rail. Such a forced guiding mechanism can make the movement of the middle support rod meet the requirements. Preferably, this movement of the middle support rod does not deflect more than 20° during the switching process of the legrest mechanism from the rest position to the use position. Here, it is best to design the forced guiding mechanism as a double linkage mechanism. The first rotating guide rail also has a second rear rotating rod, the second rear rotating rod is hinged on the seating mechanism or the base, and can rotate around a third rotating shaft with a certain distance from the second rotating shaft; the other In one aspect, the second rear rotating rod is hinged on the middle supporting rod, and can rotate around a fourth rotating shaft having a certain distance from the first rotating shaft. The first and second rear swivel rods have the same or mostly the same length between their respective hinge points, so that the displacement of the intermediate support rod is substantially in the horizontal direction.

Due to the use of the rotating guide rail between the seating mechanism or the base and the middle support rod, the vast majority of the middle support rod can always be kept below the seat surface. This property applies in particular to the individual articulation points of the first rear swivel lever and sometimes also of the second rear swivel lever. Preferably, these hinge points are arranged such that they are not affected by the position of the intermediate support bar, but remain completely under the seating surface. In this way, it is realized that the middle support rod can move relative to the seat surface or the base under the action of the first rotating guide rail, and the first rotating guide rail can be well hidden from being seen by the user. In addition, if the above-mentioned rotating rod is also designed under the seat surface in the lateral direction, the advantages are very obvious. In use, mechanical components that protrude beyond the left and right sides of the seat up to the front of the front edge of the seat are considered unsightly and often cause injury.

In principle, the first rotary guideway and the second rotary guideway can be designed to be independent of each other in terms of overall construction, so that the user can influence them separately. However, if the two rotating guide rails are mechanically coupled together so that the leg support mechanism reaches a relative position with the middle support rod according to the relative position of the middle support rod and the seating mechanism or the base, it is also very beneficial to the operation. convenience.

Accordingly, it is preferably designed such that the movement of the intermediate support rod along an arc track relative to the seating mechanism or the base will also indirectly cause the seating mechanism to move along an arc track relative to the intermediate support rod. Preferably, this mechanical coupling of the first rotating guide rail and the second rotating guide rail is designed so that the respective rotating rods of the first rotating guide rail and the second rotating guide rail can move towards opposite directions, so that the legrest mechanism can achieve a large Displacement stroke.

Preferably, a rotating rod of the first rotating guide rail and a rotating rod of the second rotating guide rail are connected to each other through a transmission rod. The movement of the leg support mechanism relative to the middle support bar should be the same as the movement direction of the middle support bar relative to the seating mechanism. In order to achieve this, an extension rod is preferably designed on the first rear rotating rod of the first rotating rail, or on the second front rotating rod of the second rotating rail, from the rotating Seen from the axis of rotation of the rod, this extension rod extends below the middle support rod, and the transmission rod is rotatably hinged on the end of the extension rod. In this way, the rotating rods of the first rotating guide rail and the second rotating guide rail can be rotated in opposite directions as expected in a very simple manner.

Furthermore, it is preferable to design the seating mechanism displaceable relative to the base of the deck chair, as described at the outset. Preferably, the movement of the seating mechanism relative to the base is mechanically coupled with the movement of the middle support rod relative to the seating mechanism. In this way, the user of the folding recliner of the utility model can switch the leg support mechanism from the rest position to the use position through the displacement of the seating mechanism relative to the base. Preferably, forward displacement of the seating mechanism relative to the base causes the legrest mechanism to switch to the use position.

Preferably, especially, the movement of the backrest of the folding recliner is mechanically coupled with the movement of the seating mechanism relative to the base, so that the movement of the backrest drives the movement of the seating mechanism, thereby causing the legrest mechanism to switch to the use position, or it is also possible to allow The movement of the seating mechanism drives the backrest to deflect.

Preferably, the deck chair works like a scale. In this case, downward movement of the seating mechanism causes upward movement of the legrest mechanism. Therefore, when the legrest mechanism is switched between the rest position and the use position, it actually utilizes the potential energy of the furniture component that needs to be lowered at this time and the user's body part resting on it, so that another furniture component and the resting position The body part above it lifts up. Therefore, the user who has been sitting on the recliner during this process only needs to apply a small external force through muscle strength or, in some designs, a motor to change the sitting posture of the recliner.

Preferably, it is designed so that the seating mechanism can move relative to the base through two displacement rods, and one end of the two displacement rods is respectively hinged on the base or the displacement mechanism described in detail below through the rotating shafts with a certain distance from each other , the other end is hinged on the seating mechanism. Using two displacement rods with rotating axes parallel to each other but at a certain distance allows the seating mechanism to be displaced relative to the base or the displacement mechanism through a very simple overall structural design. Preferably, the displacement rods are designed to have different lengths and/or are not parallel to each other, so that the seating mechanism can also be turned upside down during the rotational movement. Preferably, when the legrest mechanism is in the use position, the front edge of the seating surface is raised upwards. Preferably, the rotation angle of the displacement rod between the base and the seating mechanism is always designed to be smaller than the rotation angles of the first and second rear rotation rods between the seating mechanism and the middle support rod. Preferably, the rotation angle of the first and second rear rotation rods between the rest position and the use position of the pad surface is greater than 80°, while the rotation angle of the displacement rod is less than 60°.

In order to realize that the use position and/or the rest position of the leg rest mechanism are stable, it is preferable to take the following measures: if the leg rest mechanism is located below the seating mechanism in its rest position, preferably at least one of the displacement rods or one of the The rear swivel lever is located at a top dead center position, so that the seat mechanism only needs to be slightly lifted at least within the range of this displacement lever or the rear swivel lever at top dead center to switch the legrest mechanism to the use position. As an alternative or in addition, it is also possible to design a joystick, which can move the displacement lever or the rear rotation lever away from the dead center by means of a force exerted manually by the user.

This prevents unintentional switching of the legrest mechanism into the use position. If the legrest mechanism is in its use position, then preferably at least one of the displacement rods, preferably both displacement rods are located at a specific position, at this time, the connection line between the upper and lower hinge points of the displacement rod and the horizontal plane The angle between them is less than 60°, preferably less than 50°. This makes the switch of the leg rest mechanism from the use position towards the rest position at first need to apply relatively large active force to the leg rest mechanism, which usually cannot be done unintentionally.

The folding recliner described in the utility model is preferably designed such that the base and the seating mechanism are mutually fixed together by a displacement mechanism, and the displacement mechanism can move relative to the base, and the seating mechanism can move relative to the displacement mechanism.

The function of the displacement mechanism is to make the seating mechanism additionally realize displacement. In this way, the seating mechanism does not directly and guidedly displace relative to the base, but displaces relative to the displacement mechanism, and the displacement mechanism itself can displace relative to the base. In this way, the seating mechanism can be displaced with a large distance between its two limit positions, which is especially beneficial for the backrest of the folding recliner to be rotated backwards and downwards to a large extent without collision.

Preferably, the displacement mechanism is designed so that the displacement mechanism can move forward from a basic position along a movement path relative to the base, and the movement path is linear or nearly linear. Preferably, this linear movement can be achieved by a system of slides or a system of linkages.

Near linear movement means that when moving between the initial position and the final position, there is an error of 90° from the ideal straight line, and the error does not exceed 20% of the distance between the initial position and the final position.

Preferably, the moving distance of the displacement mechanism relative to the base is between 13cm and 15cm.

In addition, in terms of the moving path of the displacement mechanism, it is also preferable to design the moving path to be raised upward while moving forward. In this way, a force can be continuously applied to the displacement mechanism to return it to its original position. If, when the deck chair is switched to the third use position, the displacement mechanism is displaced forward along the movement path, a part of the energy provided for this is stored as potential energy. This energy assists when the deck chair is returned to its second use.

Preferably, the above-mentioned link system for displacing the displacement mechanism relative to the base is designed with at least one moving link rotatably hinged to the displacement mechanism and guided by at least two intermediate links, and The two intermediate links are rotatably hinged on the base.

It has been shown that with such a linkage system a substantially linear movement can be achieved although the individual linkages themselves can rotate. This is mainly achieved in the following manner: at least one of the moving links is hinged on the base via the first and second intermediate links, and the three distances described below are at least substantially the same. wherein the first distance is the distance between two rotational axes, wherein the first intermediate link is hinged around one rotational axis to a mobile link which is rotatably fixed to the displacement mechanism around the other rotational axis superior. The second distance is the distance between two axes of rotation about which the first intermediate link is hinged to the mobile link and the mobile link is rotatably fixed to the second intermediate link about the other axis of rotation. on the pole. The third distance is also the distance between two axes of rotation about which the first intermediate link is hinged to the mobile link and the first intermediate link is rotatably fixed to the base about the other axis of rotation .

The above three distances jointly define a moving path, along which the moving link and the rotating shaft of the displacement mechanism can move relative to the base. And there is no more than 20% error between each other (the shortest distance relative to the longest distance), so as to realize the basically linear movement as imagined.

Preferably, the backrest is rotatable around a backrest axis relative to the seating mechanism, and simultaneously the backrest axis and the seating mechanism are displaceable relative to the base. Preferably, the backrest guiding system is designed in such a way that the backrest can rotate around the backrest axis according to the relative position of the seating mechanism and the base and/or the relative position of the displacement mechanism and the base. The backrest guidance system enables the backrest to rotate according to the setting. The position of the backrest is set by the rotating shaft on one side of the seating mechanism on the one hand. On the other hand, the backrest guidance system determines how far the backrest is lowered when these swivel axes are displaced.

A possible embodiment of such a backrest guidance system is that the backrest is guided via a slideway and a slideway roller or slideway slide mounted therein. Preferably, the chute rail is designed to be fixed on the base, while the chute rollers or chute slides are fixed on the backrest.

It can also be provided that the backrest guidance system has a backrest control lever fixed to the backrest eccentric to the backrest axis, so that it is mechanically coupled to other movable parts of the deck chair. In particular, one end of the backrest control rod can be rotatably fixed on the backrest, and the other end can be rotatably fixed on the base or one of the moving links of the displacement mechanism.

In order to design the use mode of the folding recliner more simply, the first and/or second locking system is preferably designed, wherein the first locking system is designed to lock the displacement of the displacement mechanism relative to the base when the legrest mechanism is in a static state , the second locking system is designed to lock the displacement of the legrest mechanism relative to the seating mechanism when the recliner is in the third use state. In this way, by designing these two locking systems, on the one hand, it prevents the user from placing the backrest in the lying position without first placing the legrest mechanism in the use position, and on the other hand, it prevents the legrest mechanism from moving towards the Its rest position is displaced without returning the backrest to its original upright position for this purpose.

Preferably, this is achieved by the first and/or second locking system giving a maximum or minimum distance between two points, one of which is displaced with the backrest and the other with the leg pad Mechanisms move together. It turns out that it is better to design the two locking systems so as to jointly consist of two parts which press against each other, whether the deckchair is in the first or third use position, so as to produce the conceived locking effect. It is preferable to use a rotatable web attached to the backrest with a slotted hole at one end forming one of the fittings, the other being a bolt stop in the slotted hole. constitute.

In addition, it is preferable to design a spring device on the folding recliner, and when the leg rest mechanism is switched from the use position to the rest position, and/or when the leg rest mechanism is switched from the rest position to the use position, a reverse force is applied respectively. In this way, the stability in the rest position and in the use position is increased.

In order to achieve the effect of stabilizing the use position and the rest position, the spring device is preferably arranged between the hinge points of the various components of the folding recliner, and the arrangement of these hinge points makes the spring be firstly activated when the cushion surface is switched from the rest position to the use position. Stretch, then return to original length.

This requires mechanical energy to be applied to the spring means both when leaving the use position and the rest position.

In addition, the utility model also relates to an accessory system of a folding recliner, whose function is to cause the above-mentioned relative movement between the seating mechanism and the leg resting mechanism.

detailed description

Embodiment one:

Fig. 1a shows a folding recliner 10 according to the present invention, which is designed as a sofa chair with upholstery.

The deck chair 10 has three components that can move toward each other and have cushions respectively, that is, a seating mechanism 12 , a legrest mechanism 14 and a backrest 16 .

Furthermore, the deck chair 10 has a base 18 which forms the base of the deck chair. One end of the base 18 is connected to the ground 1 , and the other end is connected to the wall 2 on the back side of the deck chair 10 . The folding recliner 10 has a moving mechanism 20, which is mainly shown as an accessory system 22 shown in FIG. Use the position shown in 3b for relative movement.

In the following, the main components of this accessory system 22 are explained with reference to FIG. 1b. The attachment system 22 has two metal fastening plates 24 that are fixedly connected to the base 18 . Furthermore, the attachment system 22 has a frame 26 which, in a manner not shown in the figure, serves to fix the mount 12 and therefore always moves together with the mount 12 . Furthermore, in order to hold the leg rest 14 in place, the attachment system 22 has a support plate 28 whose position relative to the leg rest 14 remains constant.

These components are connected together as described below. Some of the below-mentioned components of the accessory system 22 are arranged on the left and right sides of the seating surface, respectively, and are designed to move in unison. Here, only the components of one side are described respectively.

Two displacement rods are designed between the metal fixing plate 24 fixed on the base 18 and the frame 26 fixed on the seating mechanism, namely the front displacement rod 32 and the rear displacement rod 34, which can respectively surround the The front displacement rod lower shaft 32a and the backrest shaft 34a extending in the direction of the base 18 rotate, and can also respectively surround a front displacement rod middle shaft 32b and a rear displacement rod that extend along the transverse direction of the furniture and are fixed on the frame. The upper shaft 34b rotates. As a result, the movable range of the seating mechanism 12 relative to the base 18 is basically given, and at the same time, through the small difference in length between the two displacement rods and/or the difference between the two displacement rods in Figures 1a and 1b The orientation when showing the rest position forces the seating mechanism 12 to turn up and down relative to the base 18 during its movement.

Between the frame 26 and the middle support rod 30 positioned below the frame 26, two rotating rods have been designed, i.e. the first rear rotating rod 36 and the second rear rotating rod 38. These two rotating rods can respectively surround two The first rotating shaft 36c and the fourth rotating shaft 38c, which are fixed in mutual position and installed on the middle connecting rod, can also rotate around the second rotating shaft 36b and the third rotating shaft installed on the frame 26. 38b rotates. That is, a forced guide mechanism is formed between the frame 26 and the intermediate support rod 30 . Under the effect of this forced guiding mechanism, the middle support rod 30 can only move along the movement path given by the first rear rotating rod 36 and the second rear rotating rod 38 constituting the first rotating guide rail. Since the respective rotation shafts of the first rear rotation rod 36 and the second rear rotation rod 38 are connected to the frame 26, that is, the second rotation shaft 36b and the third rotation shaft 38b, keep substantially the same distance, only in the middle support rod 30 will move relative to the frame 26 only when it is flipped up and down in a small range.

The movement of the frame 26 relative to the base 18 and the movement of the intermediate support rod 30 relative to the frame 26 are mechanically coupled to each other. A displacement coupling rod 40 is designed for this purpose, one end of which is rotatably hinged on the extension rod of the front displacement rod 32 and the other end is rotatably hinged on the second rear rotation rod 38 . The result of this design is that the movement of the seating mechanism 12 relative to the base 18 will also cause the middle support rod 30 to move relative to the frame 26 . This will be explained in detail below.

The middle support rod 30 is mainly composed of a hollow tube extending along the longitudinal axis of the furniture.

At the front end of the middle support rod 30, the previously mentioned support plate 28 of the leg resting mechanism 14 is fixed. This fixation is realized by two front rotating rods, i.e. a first front rotating rod 42 and a second front rotating rod 44, which are respectively connected to the middle support rod 30 and can surround the first The fifth rotating shaft 42a and the seventh rotating shaft 44a rotate; they are also respectively connected to the support plate 28, and can rotate around the sixth rotating shaft 42b and the eighth rotating shaft 44b. This is similar to how the frame 26 is fixed on the base 18 and the middle support rod 30 is fixed on the frame 26, forming a forced guiding mechanism. Thus, the movement path of the support plate 28 relative to the middle support rod 30 is determined by the first front rotation rod 42 and the second front rotation rod 44 . There is a small difference in length between the first front swivel rod 42 and the second front swivel rod 44 between their respective axes of rotation so that the support plate 28 and the leg rest mechanism 14 move relative to the middle support rod 30 while , the legrest mechanism 14 is also slightly inclined relative to the middle support rod 30 according to the setting.

In order to displace the support plate 28 relative to the intermediate support rod 30, a transmission rod 58 is designed. One end of this transmission rod 58 is rotatably hinged on the first rear rotating rod 36 , and the other end is rotatably hinged on the first front rotating rod 42 . In this case, one end of the transmission rod 58 is hinged on the first rear rotating rod 36, on the upper side of the first rotating shaft 36c, and the other end is connected on the first front rotating rod 42, on the fifth rotating shaft 42a. Below, the end of the extension rod of the first front rotating rod 42. The mode of this layout has just guaranteed, and the rotational motion of first rear portion rotating rod 36 and second rear portion rotating rod 38 is opposite to the rotating motion of first front portion rotating rod 42 and second front portion rotating rod 44 . As shown in Fig. 1b, a side view of Fig. 1a, if the first rear rotating rod 36 for forward displacement of the intermediate support rod 30 is rotated counterclockwise, this rotation will cause the first front part through the transmission rod 58. The rotation lever 42 rotates clockwise.

This provides a mobile structure in which all components are fully mechanically coupled. The arrangement of all other components of the accessory system 22 is determined by the relative position of the seating mechanism 12 relative to the base 18 , which is influenced by the user.

In the deck chair 10 shown in FIGS. 1 a and 1 b , the backrest 16 is fastened to a backrest support plate 90 . This backrest support plate 90 is rotatable relative to the seating mechanism 12 and its frame 26 . In this embodiment and the following embodiments, this rotation axis is the upper axis 34b of the rear displacement rod.

In order to realize the mechanical coupling of the movement of the seating mechanism 12 relative to the base 18, the back support plate 90 is rotatably hinged on the back control rod 92, and the other end of the latter is rotatably fixed to the metal fixing plate on one side of the base 18. 24 on. Since the orientations of the rear displacement rod 34 and the backrest control rod 92 deviate from each other, the rear displacement rod 34 rotates forward during the displacement process of the seating mechanism 12 relative to the base 18, which will cause the backrest support plate 90 to rotate relative to each other. Rotate on the base 18. Like this, along with stretching out of cushion surface 14a, backrest 16 just rotates backward very easily.

Therefore, in summary, the embodiments of FIGS. 1 to 3 have the following mechanically coupled components. Relative to the seating mechanism 12 and its frame 26, the middle support rod 30 can rotate forward from the first use position shown in FIG. The rod 30 is rotated forward. The user sitting on the recliner 10 operates the joystick 37 and/or applies a force to the seating mechanism 12 at the same time, so that the middle support rod 30 and the support plate 28 are displaced forward. In this way, the seating mechanism 12 and its frame 26 can be displaced forward relative to the base 18 . This movement is forcibly coupled together by the rotational movement of the displacement coupling rod 40 and the intermediate support rod 30 . Additionally, the forward movement of the seating mechanism 12 and frame 26 also rotates the backrest 16 to a more horizontal, more comfortable position.

In the initial state shown in FIGS. 1a and 1b , the legrest mechanism 14 is located below the seating mechanism 12 , and the recliner 10 functions as a simple sofa chair at this moment. In this state, the rear displacement rod 34 extends substantially vertically so that the rear end of the seating surface 12a is located at its highest attainable position. According to FIG. 1 a , in order to displace the leg support mechanism 14 , it is necessary to rotate the front displacement rod 32 and the rear displacement rod 34 coupled with the movement of the intermediate support rod 30 through the displacement coupling rod 40 clockwise. The stability of the initial position is ensured by a spring 56, the spring 58 is hinged on the first rear rotating rod 36 and the second rear rotating rod 38, and is elongated when the seating mechanism 12 is displaced relative to the base 18 .

In order to switch the deck chair into the state shown in FIGS. 3a, 3b, the user has to displace the central support bar 30 forwards. Preferably, the user should lean on the backrest 16, thereby displacing the seating mechanism 12 forward. Similarly, this movement can also be realized by means of the joystick 37, that is, to apply a starting thrust for the state switching of the deck chair.

Figure 2a shows the intermediate state thus achieved. The front displacement rod 32 is coupled with the second rear rotation rod 38 through the displacement coupling rod 40 , so that the displacement of the seating mechanism 12 causes the leg support mechanism 14 to be displaced relative to the seating mechanism 12 at the same time. Especially under the guidance of the first rear rotating rod 36 and the second rear rotating rod 38, the leg rest mechanism 14 continues to move forward without rotating. However, the displacement of the leg support mechanism 14 is not restricted by the first rear rotating rod 36 and the second rear rotating rod 38 , that is, the displacement stroke of the middle support rod 30 is restricted. Rather, because the support plate 28 and its first front rotating rod 42 are mechanically coupled with the middle support rod 30 and its first rear rotating rod 36 through the transmission rod 58, the supporting plate 28 is further displaced auxiliary. In this way, the displacement of the legrest mechanism 14 relative to the seating mechanism 12 is composed of the rotational movement of the intermediate support rod 30 relative to the frame 26 and the rotational movement of the support plate 28 relative to the intermediate support rod 30 .

On further movement, the state shown in Figures 3a and 3b is reached. By the circular track where the middle support rod 30 moves, the leg resting mechanism 14 is lifted up when the relative movement with the seating mechanism 12 is near the end, so that the pad surface 14a on the surface of the leg resting mechanism 14 is near the end of the movement. It is positioned at the same height as the sitting surface 12a.

According to the mode shown in the figure, the seat mechanism 12 is displaced from the initial state shown in Fig. 1a, 1b to the position shown in Fig. The user feels a comfortable position without having the backrest 16 contact the wall 2 . This is achieved by displacement of the legrest mechanism 14 .

Embodiment two:

In the second embodiment shown in Fig. 4 to Fig. 6, all mechanical components of the seating mechanism 12 and the frame 26 on one side thereof and the middle support rod 30, the support plate 28 and the leg resting mechanism 14 are the same as those in Fig. 1 to 3 are exactly the same in the embodiments, so the above description can also be referred to.

The special feature of the second embodiment shown in Figs. 4 to 6 and the third embodiment described in Figs. It is used between the first use position (the leg resting mechanism 14 is located below the seating mechanism 12) and the second use position (the leg resting mechanism 14 is located in front of the seating mechanism 12), and it also has a third use position. The legrest mechanism 14 is in the extended state, and the backrest 16 is significantly lowered, so that the user can comfortably lie on the folding recliner.

In this case, it is desirable that the backrest 16 in the third use position has no rearward displacement or only a small displacement backward relative to the first use position, although it faces the user to lie down. , so that the recliner 10 can be substantially flush with the wall 2 in the first use position, but can be switched to the third use position nonetheless and allows the user to lie down without being hindered by the wall 2 Movement of the backrest 16 .

In order to achieve this purpose, it is designed in this embodiment and the following embodiment three: the displacement distance of the seating mechanism is not limited to the distance that the front displacement rod 32 and the rear displacement rod 34 can reach. In addition, a displacement mechanism 80 is also designed, which is located between the base 18 and the seating mechanism 12 and its frame 26, and can also be displaced forward.

It can be clearly seen from FIG. 4 b that the displacement mechanism 80 replaces the metal fixing plate 24 on the side of the base 18 in the first embodiment in terms of fixing the front displacement rod 32 and the rear displacement rod 34 . The seating mechanism 12 and its frame 26 directly, the intermediate support rod 30 and the support plate 28 can move relative to the displacement mechanism 80 indirectly, as in the first embodiment shown in FIGS. 1 to 3 . The movement of the base and its metal fixing plate 24 is the same.

However, in the embodiments shown in FIGS. 4 to 6 , the displacement mechanism 80 itself can also move relative to the base 18 . In this way, the movable range of the seating mechanism 12 relative to the base 18 is enlarged again. The movement of the displacement mechanism 80 relative to the base 18 is achieved by two chute guide rails, namely the rear chute guide rail 18b and the front chute guide rail 18c. These two chute guide rails are designed on the side of the base 18, and a A rear chute roller 82 b and a front chute roller 82 a are rotatably supported in the displacement mechanism 80 . The rear chute rail 18b and the front chute rail 18c slope upward slightly while extending forward.

Since the third use state of the folding recliner 10 is provided in the second embodiment shown in FIGS. 4 to 6 , so that the user can lie down, it is different from the design scheme shown in FIGS. The back support plate 90 is coupled with the other components of the deck chair 10 .

There is also a backrest chute guide rail 18 a on both sides of the backrest support plate 90 , which is also designed on the side of the base 18 . The following further elaborates on the technical thinking of this design scheme.

As can be seen from the transition from the first state of use shown in FIGS. 4a and 4b to the second state of use shown in FIGS. The positions in the rear chute guide 18b and the front chute guide 18c initially remain unchanged. As an alternative solution, the legrest mechanism 14 and the intermediate support rod 30 move during this transition as in the first embodiment shown in FIGS. 1 to 3 .

When transitioning to the second state of use shown in Figures 5a and 5b, the rear chute roller 82b and the front chute roller 82a remain in the initial position. Determined by the orientation of the slope. But, in the first transition stage to the second use state, in order to prevent the displacement mechanism 80 from being displaced intentionally or unintentionally, a connecting piece 94 is rotatably designed on the back support plate 90, and this connecting piece 94 A long hole 94a has been designed on it. A bolt stopper 32c is inserted in this elongated hole 94a, and this stopper 32c is positioned at the front end of front displacement rod 32, rear displacement rod 34, when the first use state shown in Fig. 4a, 4b is close to by long On the stop area formed by the end of the hole 94a. In this way, when the first use state shown in FIGS. 4a and 4b, the stopper 32c and the slot 94a can prevent the backrest 16 from descending immediately.

Therefore, in the process of transitioning from the first use state shown in Figs. 4a, 4b to the second use state shown in Figs. 5a, 5b, the backrest 16 will only descend slightly downwards. This small drop is determined by the molding of the backrest runner guide rail 18a. If the seating mechanism 12 and its frame 26 are displaced forward during the transition to the second use state, the rear displacement rod upper shaft 34b of the backrest 16 also displaces forward, and the backrest 16 is in the backrest chute guide rail 18a. Slight rotation occurs under the guidance of the backrest chute roller 96. According to another configuration of the backrest runner guide 18a described in the preceding paragraph, a design can also be realized in principle, that is, the backrest 16 does not rotate when passing from the first use position to the second use position .

If the second use state shown in Fig. 5a, 5b is reached, then according to the second use state shown in Fig. 2a, 2b corresponding to the previous embodiment one, the front displacement rod 32 and the rear displacement rod 34 rotate forward . Thus, the stopper 34c on the front displacement rod 32 is also located at the end opposite to the long hole 94a of the corresponding connecting piece 94, that is, the front end.

Therefore, the folding recliner 10 adopting this design can switch from the second use position to the third use position shown in FIGS. Switching to the third operating position is initiated by the user sitting on the recliner, that is to say the user leans his back against the backrest 16 and/or pulls the seating mechanism 12 forward. In this way, the backrest runner roller 96 in the backrest runner guide rail 18a is pressed forward further beyond the position shown in FIGS. 5a, 5b. This forces the displacement mechanism 80 to move forward relative to the base 18 together with the seating mechanism 12 and the outwardly stretched leg pad mechanism 14, which is through the rear chute rollers in the rear chute guide rail 18b and the front chute guide rail 18c. 82b and the rolling of front chute roller 82a are realized. In addition to the forward displacement of these mechanisms, due to the upwardly inclined orientation of the rear chute guide 18b and the front chute guide 18c, this also causes a small upward displacement of the displacement mechanism 80 and the seating mechanism 12 .

From the comparison of Figures 5a, 5b and 6a, 6b, it can be seen that all mechanical components that affect the movement of the seating mechanism 12 relative to the displacement mechanism 80, and the movement of the middle support rod 30 and the support plate 28 relative to the seating mechanism 12 , the mutual position remains unchanged during the process of switching to the third use state shown in Fig. 6a, 6b. All of these components are displaced collectively forward and slightly upward. During the switchover to the third operating position, only the backrest support plate 90 and the connecting piece 94 pivotally hinged thereon and having the elongated hole 94a move relative to these mechanical components.

In the third use state shown in FIGS. 6 a and 6 b , the user can comfortably lie on the folding recliner 10 , at this time the backrest 16 rotates to a large extent, and the leg rest mechanism 14 stretches out.

When the recliner 10 is transferred back, it is better to allow the backrest 16 to return to a relatively steep position, instead of allowing the leg rest mechanism 14 to displace relative to the seating mechanism 12 toward its rest position. The elongated hole 94a stop zone just plays this purpose. As shown in Figures 6a and 6b, the stopper 32c is also in close contact with the stopper area at the end of the elongated hole 94a in the third use state. Therefore, the leg rest mechanism 14 cannot be rotated directly, thereby indirectly causing the rotation of the front displacement rod 32 . Just when the back support rod 90 is rotated back toward its vertical direction, the slot 94a will be displaced, thereby allowing the legrest mechanism 14 to move. When switching back from the third use state to the second use state, the weight of the user sitting on the recliner 10 is utilized, that is to say, the user slides the rear chute guide rail 18b and the front chute guide rail 18c through the body weight. The groove roller 82b and the front chute roller 82a are pressed back to their original positions.

Embodiment three:

The third embodiment shown in FIGS. 7 to 10 is functionally very similar to the second embodiment described in FIGS. 4 to 6 . The deck chair 10 equipped with the accessory system 22 described in FIGS. Leg mechanism 14 retracts inwardly, and during the second use state, leg rest mechanism 14 stretches out outwards, and backrest 16 rotates greatly when leg rest mechanism 14 stretches out during the third use state, so that allow The user can lie down.

In contrast to the configurations shown in FIGS. 4 to 6 , the slotted guide rails are omitted here. As an alternative, a supplementary linkage system 70 is designed, which takes over the function of the chute guide.

FIG. 7 is an exploded view. For the convenience of description, the connecting rod system 70 in the figure has been removed from the displacement mechanism 80 . First of all, it can be determined for this figure that the displacement mechanism 80, the seating mechanism 12 and the frame 26 rotatably supported by the displacement rods 32, 34, the intermediate support rod 30 and the frame 26 rotatably supported on the seating mechanism 12 The movable support plate 28 opposite it, this whole set of components is functionally basically the same as the design scheme shown in FIGS. 4 to 6 . The only structural difference is that the chute rollers are canceled and a backrest control rod 92 for fixing the backrest support rod 90 is additionally designed.

The auxiliary link system 70 has a metal fixed plate 71 fixed on the base, and two moving links, namely a rear moving link 72 and a front moving link 74, can be displaced relative to the metal fixing plate 71. The rear moving link 72 and the front moving link 74 are respectively not directly, but indirectly and rotatably fixed on the metal fixing plate 71 through another intermediate link. Both the rear moving link 72 and the front moving link 74 have bore holes constraining the axes of rotation, i.e. the rear moving link central axis 72a and the first turning axis 74a, within the range of these two turning axes the displacement mechanism 80 is rotatable. Be connected on the rear moving link 72 and the front moving link 74.

By means of the middle link, the rear moving link 72 and the front moving link 74 can move relative to the metal fixed plate 71 according to the setting, which ensures the movable range of the displacement mechanism 80 relative to the metal fixed plate 71, which can The moving range is basically equivalent to the movable range achieved by the chute guide rail in Fig. 4 to Fig. 6 . An intermediate link ensures essentially linear movement.

Before moving the connecting rod 74 as an example, this is explained. The front moving link 74 is fixed on the metal fixing plate 71 through two rotatable intermediate links, that is, a first intermediate link 75 and a second intermediate link 76 . Here, the lower first intermediate link 75 is of great importance. This first intermediate link 75 is coordinated with the front moving link 74, and the specific way to achieve this is that the first rotating shaft 74a (within its rotation range, the displacement mechanism 80 is fixed on the front moving link 74) and the second The distance between the two rotating shafts 74b (within its rotational range, the intermediate link 75 is rotatably fixed on the moving link 74) is substantially equivalent to the distance between the second rotating shaft 74b and the fourth rotating shaft 75a, Thus, the first intermediate link 75 is rotatably hinged on the metal fixing plate 71 . At the same time, this distance is also substantially equivalent to the distance between the second rotation axis 74b and the third rotation axis 74c, through which the second intermediate link 76 is hinged on the front moving link 74.

Owing to, the distance between the first rotation axis 74a and the second rotation axis 74b, the second rotation axis 74b and the fourth rotation axis 75a, the second rotation axis 74b and the third rotation axis 74c are equal or substantially equal, so that The first rotation shaft 74a can move substantially linearly relative to the metal fixing plate 71 as conceived. In Figures 8a, 9a and 10a this movement is marked with a dotted line. Similar to rear chute rail 18b, front chute rail 18c, this line is inclined upwards by 15° while extending forward.

As for the rear travel link 72, basically the same design as this can also be used. But in order to save space, a different design scheme has been selected here, that is, the movable range that has been set by the front moving link 74 by a link coupling bar 78; A third intermediate link 73 that basically plays the same role as the first intermediate link 75 is provided. However, the connecting rod corresponding to the second intermediate connecting rod 76 has been omitted in this design. As an alternative, the path of movement of the central axis 72 a of the rear movement link is achieved substantially parallel to the path of movement of the first pivot axis 74 a via the link coupling rod 78 .

In this way, the link system 70 can finally replace the rear chute guide rail 18b and the front chute guide rail 18c in the second embodiment above. This ensures that the moving mechanism 80 can move relative to the base 18, which is basically the same as the previous second embodiment.

What is different from the designs shown in FIGS. 4 to 6 is that this embodiment also designs a fixing method for the back support rod 90 . For this purpose, a backrest control lever 92 is designed essentially in the same manner as in the embodiment shown in FIGS. 1 to 3 . However, the backrest control lever 92 cannot be rotatably articulated to the displacement mechanism 80 in the manner shown in FIGS. Auxiliary rotation, since the backrest rotation axis 34 a is no longer displaced relative to the displacement mechanism 80 during this transition.

Therefore, instead, this back control lever 92 is rotatably fixed on the rear travel link 72 which rotates around the rear travel link lower shaft 72d in the manner shown in FIG. 7 .

The seating furniture 10 adopting the above-mentioned structure can be switched from the first use state to the second use state, and continue to switch to the third use state, which is basically the same as the second embodiment above.

From the first state of use shown in Figures 8a and 8b, the assembly of the seating mechanism 12 and its frame 26 that can remain constant relative to the mutual position of the displacement mechanism 80, and the linkage system 70 fixed on the base 18 to The forward displacement makes the leg resting mechanism 14 protrude outwards in the same manner as the first and second embodiments described above. After reaching the second use state shown in Figures 9a and 9b, the seating mechanism 12 is further displaced forward, and an active force is applied to the backrest 16 and the backrest support rod 90, due to the mechanical coupling through the backrest control rod 92 , the first rotating shaft 74a and the rear moving link center shaft 72a can move forward relative to the metal fixing plate 71 fixed on the base 18 in a linear manner along the dotted line and slightly upward, and the backrest 16 also moves forward at the same time. to rotate. In the third use state shown in Figures 10a and 10b, the recliner 10 allows the user to lie down comfortably.

These embodiments are exemplary and are only used to illustrate the invention and its various aspects. It is obvious to those skilled in the art that these embodiments may have modifications without departing from the gist of the present utility model.

It is expressly pointed out here that various configurations are conceivable within the scope of the invention, in which parts of the attachment system 22 can be located on one side of the seat surface as well as on both sides of the seat surface. Preferably, but not mandatory, the components that ensure the relative movement of the displacement mechanism are designed on both sides of the seat surface. This is especially applicable to the fixing of the first rear rotating rod 36, the second rear rotating rod 38 and the seating mechanism frame 26, the fixing of the frame 26 and the metal fixed plate 24 or the frame 26 passing through the front displacement rod 32, the rear displacement rod 34 Fixing to the displacement mechanism 80 , as well as the slide system 18 a , 18 b , 18 c , 82 a , 82 b , 96 or the corresponding linkage system 70 . Preferably, the other components forcibly coupling the individual relative movements are distributed on one side, but can also be evenly distributed on both sides. For example, this applies to the transmission rod 58 that couples the two rotating rails, the displacement coupling rod 40 that mechanically couples the movement of the middle support rod 30 to the seat frame 26, and the seat frame 26 or the displacement mechanism 80. The movement of the backrest 16 is mechanically coupled with the backrest control lever 92.

In addition, it is obvious to those skilled in the art that the technology described in the present utility model is only exemplarily explained based on a single-seater sofa chair, but these technical solutions can also be simply or multiplely applied to a couch .

It is also obvious to those skilled in the art that the reclining chair 10 of the present invention may also include other components that are fixed relative to the components described above, or that can move independently. This mainly just comprises handrail wherein, preferably it can be designed on the seating mechanism and fixed.

In addition, those skilled in the art will recognize that the specific elements described above that are fixed to the various components, base, seating mechanism, legrest mechanism and backrest are only exemplary. For example, the metal fixing plates 24, 71 and the side assemblies of the base 18, the frame 26, the middle support bar 30, the support plate 28 of the legrest mechanism 14, and the back support plate 90 can be fixed by other suitable functions, especially the connecting rods and The assembly of the chute guide rail is replaced without departing from the gist of the present utility model.
