Description

Movable rocking chair or rocking chair
Technical Field
The utility model relates to a movable rocking chair or rocking chair.
Background
A variety of movable seating devices are known in the art, such as rocking chairs, swinging chairs with rocking sofa or rocking chairs. The seat typically has a base, a back rest support, a seat support, a tilt mechanism, and is capable of changing between several different positions. However, the known seating devices do not generally satisfy the comfort requirements of the user, for example, the user has to perform the above-described posture changes in a manually operated manner with great effort, or the posture is preset in an excessive amount, so that the user must go through a long changing process to finally obtain the desired seat posture. Obviously, this also leads to a more complex structure of the seating furniture, with a higher risk of failure and higher manufacturing and maintenance costs.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a rocking chair or a rocking chair which has simpler structure, simpler operation and lower manufacturing cost.
To solve the above technical problems, the present invention provides a movable rocking chair or rocking chair, which comprises
-a base for supporting on a ground surface,
-a seat part located above the base,
a backrest located behind the seat part,
-a footrest located in front of or below the seat part,
-a rocking or rocking mechanism for providing said rocking chair or rocking chair with a rocking or rocking function, and
a tilting mechanism comprising a multi-link mechanism and intended to be attached to a seat portion, a backrest and a footrest of a swing chair or rocking chair and configured to enable the swing chair or rocking chair to be changed between two end positions, namely a sitting position in which the footrest is folded under the seat portion and a lying position; in the lying position, the backrest is inclined backwards and the footrest extends forwards in front of the seat part;
an electric actuation unit for changing the pendulum chair or rocking chair between the sitting position and the lying position.
According to the utility model, the tilting mechanism is configured such that the change of the pendulum or rocking chair between the sitting position and the lying position is effected by means of the electric actuating unit, wherein, when the pendulum or rocking chair is changed from the sitting position to the lying position, the footrest is extended forward to in front of the seat part while the backrest is tilted backward, and, when the pendulum or rocking chair is changed from the lying position to the sitting position, the footrest is returned backward to be folded under the seat part while the backrest is returned forward to be tilted.
The utility model is based on the idea that the rocking chair or rocking chair can be changed between two end positions only, i.e. between the sitting position and the lying position which are most common for the user, and that the change of the position of the backrest and the change of the position of the footrest take place simultaneously. This, on the one hand, eliminates the less common seat position, makes the associated design simpler and less expensive to produce, and on the other hand, the user can thus obtain his desired seat position in the most convenient manner. Furthermore, the change of the two end positions is effected by the electric actuator unit, whereby the user can operate the rocking chair or rocking chair with little effort.
In a preferred design, the reclining mechanism includes a leg stretching unit for mounting the footrest, a seat bracket for mounting the seat portion, and a backrest bracket for mounting the backrest, which are pivotally connected in this order.
In a preferred design, the tilt mechanism is configured to allow the chair or bouncer in the sitting position to rock or rock back and forth relative to the ground, and not in the recumbent position. To achieve this, the reclining mechanism includes a swing limiting mechanism designed to allow the seat and backrest brackets of the reclining mechanism to swing back and forth relative to the base of the swing chair or rocking chair in a sitting position and to prevent the seat bracket from swinging back and forth relative to the base in a recumbent position.
The leg stretching units are connected with front cross rods, the seat support is fixedly connected with rear cross rods, and the front cross rods can move forwards relative to the rear cross rods through the electric actuating units so that the footrest can move to the front of the seat portion.
In a particularly preferred embodiment, the rear transverse bar is directly or indirectly fixed or rigidly connected to the seat carrier.
In a particularly preferred embodiment, the tilting mechanism further comprises a linkage for linking the leg extension unit to the backrest support, which linkage is pivotally connected to the backrest support and to the leg extension unit, so that the backrest support can be tilted backwards about a backrest pivot point, at which the backrest support is pivotally connected to the seat support, while the leg extension unit is extended forwards, and the backrest support can be tilted forwards about the backrest pivot point while the leg extension unit is retracted backwards.
In one embodiment, the linkage is formed at least by a linkage link of one-piece design, by which a synchronous movement of the backrest support and the leg extension unit is achieved by a pivotal connection of the linkage link to the backrest support on the one hand and to the leg extension unit on the other hand. In this embodiment, the coupling link is directly pivoted at one end to the backrest support and at its other end to the leg extension unit, preferably to the foot bar of the leg extension unit closest to the seat support.
In this embodiment, the linkage preferably also comprises a backrest connection in addition to the linkage for structural stability. The backrest connecting piece is pivotally connected at its upper end to the backrest support at a pivot point behind the backrest pivot point, the backrest connecting piece is pivotally connected at its lower end to the rear end of the linkage link, and the front end of the linkage link is pivotally connected to the leg extension unit, preferably to the foot bar of the leg extension unit closest to the seat support. In this case, the backrest support is turned backward in synchronization with the leg extension units being extended forward, and the backrest support is turned forward in synchronization with the leg extension units being retracted backward by a simple linkage, so that the change of the swing chair or the rocking chair between the sitting position and the lying position is achieved in a simple and reliable manner.
In order to further advantageously enable the change of the rocking chair or rocking chair between the sitting position and the lying position, it is further preferred that the rocking or swiveling mechanism comprises a transmission connecting rod fixedly connected to the seat support, wherein a support link is provided between the transmission connecting rod and the seat support, which support link is connected, preferably fixedly connected, or also pivotably connected, at one end to the transmission connecting rod and is fixedly connected at the other end to the seat support, so as to enable the fixing of the relative position between the transmission connecting rod and the seat support. By this design, it is particularly effective to stabilize the position of the seat support relative to the rocking or swiveling mechanism during a change of posture of the swing chair or rocking chair, so that the pivotal connection between the seat support and the backrest support, i.e. the position of the backrest pivot point relative to the rocking or swiveling mechanism, is maintained, facilitating the backrest support to be turned forwards or backwards by the backrest pivot point under the influence of the backrest connection.
In a preferred embodiment, the electric actuating unit is designed as a linear motor unit, the components of which are connected to the front transverse bar and the rear transverse bar, respectively.
In this embodiment, it is preferred that the linear motor unit comprises a motor head, a motor slide connected to the motor head, and a motor slide slidable relative to the motor slide. One end of the electric actuating unit, such as a motor head, is pivotally connected to a front cross bar fixedly connected with the leg stretching unit, and the other end of the electric actuating unit, such as a motor sliding block, is pivotally connected to a rear cross bar fixedly connected with the seat support, so that when the motor head moves longitudinally along the longitudinal axis of the motor sliding rail relative to the motor sliding block, the front cross bar drives the leg stretching unit to expand forwards or retract backwards, and the swing chair or the rocking chair is changed between a sitting posture position and a lying posture position. Of course, the opposite design is also possible, for example, the motor slide of the electric actuating unit is pivotally connected to the front cross bar fixedly connected to the leg stretching unit, and the motor head of the electric actuating unit is pivotally connected to the rear cross bar fixedly connected to the seat support.
The rocking chair or vice versa further comprises a base for supporting directly on the ground, the rocking or swiveling mechanism being fixedly supported on the base. The base may be a circular support designed to rest on the ground, to which a fixed support consisting of a set of parallel extending support bars is rotatably connected, so that the chair or rocking chair has a swivel function as well as a tilt, swing/rock function. Alternatively, the base may simply be configured as a set of parallel extending ground-contacting supports supported directly on the ground.

Detailed Description
For clarity, additional components such as seat cushions, back cushions, and footrest are omitted from the figures.
First, fig. 1 schematically shows an embodiment of a pendulum chair according to the utility model. The swing chair comprises: a base 1, a tilting mechanism 2, a swinging or rocking mechanism 3 (in the solution of the chair shown in fig. 1, in particular a swinging mechanism providing a swinging function), an electric actuating unit 4.
The base 1 can be designed as shown in fig. 1 as a circular support 11 which rests on the ground and to which a fastening bracket 12 consisting of a set of parallel supporting rods is rotatably connected.
Alternatively, in other embodiments not shown, the base 1 may also be configured as a set of parallel extending ground-contacting supports supported directly on the ground.
Above the base 1, in particular in the exemplary embodiment shown in fig. 1, a tilting mechanism 2 is fixedly connected to the fixed support 12. The tilting mechanism is arranged mirror-symmetrically on the left and right with reference to the longitudinal direction of the swing chair, of which only half is shown and specifically illustrated here for the sake of simplicity. The reclining mechanism includes a seat bracket 21, a backrest bracket 22, and a leg stretching unit 23.
In this embodiment, the backrest support 22 is configured with a horizontal section 221 extending substantially horizontally in the sitting position, at the front end of which is pivotably connected with the rear end of the seat support 21 at a backrest pivot point M about which the backrest support 22 can be flipped back and forth, and a vertical section 222 extending substantially vertically.
As shown in fig. 1 to 4, the leg stretching unit 23 is composed of a plurality of links pivotally connected to each other, wherein the seat bracket 21 is pivotally connected to the rear end of the front link 230 at a first pivot point a, the front end of the front link 230 is pivotally connected to the rear end of the first foot bar 231 at a second pivot point B, the front ends of the first and second foot bars 231 and 232 are respectively pivotally connected to the footrest support plate 234, the rear end of the second foot bar 232 is pivotally connected to the front end of the third foot bar 233 at a third pivot point C, the rear end of the third foot bar 233 is pivotally connected to the seat bracket 3 at a fourth pivot point D, and the second foot bar 232 is in turn pivotally connected to the front link 230 at a fifth pivot point E.
As shown in fig. 2 and 4, the recliner mechanism 2 further includes a linkage 24, the linkage 24 including a backrest connector 241 and a linkage link 242 extending generally in the longitudinal direction of the swing chair. In the illustrated design, the linkage link 242 is pivotally connected at its front end to the middle of the third leg 233 of the leg unit 23 at a sixth pivot point F, the linkage link 242 is pivotally connected at its rear end to the backrest connection 241 at a seventh pivot point G, and the backrest connection 241 is pivotally connected to the backrest bracket 22 at an eighth pivot point H.
The rocking chair or rocking chair also comprises a corresponding rocking or wagging mechanism 3. As shown in fig. 1 and 3 in particular, the pivoting or swiveling mechanism 3 is in each case embodied as a swiveling mechanism for a swiveling chair, comprising a swiveling base plate 31, a front swiveling lever 32, a rear swiveling lever 33 and a transmission connecting rod 34, wherein the bottom of the swiveling base plate 31 is fixedly connected to the fixed support 12 of the base 1, the swiveling base plate 31 is pivotably connected with its top front end to the top end of the front swiveling lever 32, the swiveling base plate 31 is pivotably connected with its top rear end to the top end of the rear swiveling lever 33, and the lower end of the front swiveling lever 32 and the lower end of the rear swiveling lever 33 are each pivotably connected with a longitudinally extending transmission connecting rod 34.
Preferably in the embodiment shown, the transmission connecting rod 34 is fixedly connected, in particular riveted or welded, with its front end to the seat support 21 and is pivotably connected with its rear end via a rear connecting piece 243 to the backrest connecting piece 241. In the illustrated design, the top end of the rear link 243 is pivotally connected to the back link 241 at a ninth pivot point I, and the lower end of the rear link 243 is pivotally connected to the rear end of the drive link 34 at a tenth pivot point J.
In a preferred embodiment, a support link 35 is additionally provided between the transmission connecting rod 34 and the seat support 21, said support link 35 being pivotably connected at one end to the transmission connecting rod 34 and being fixedly connected at its other end to the seat support 21, so that in conjunction with the fixed connection of the transmission connecting rod 34 to the seat support 21, a fixing of the relative position between the transmission connecting rod 34 and the seat support 21 is achieved.
As shown in particular in fig. 1 and 3, the swing chair further comprises an electric actuating unit 4, which in this embodiment is a linear motor unit, comprising a motor head 41, a motor slide 42 connected to the motor head 41, and a motor slider 43 slidable relative to the motor slide 42, wherein the motor head 41 is pivotably connected to a front crossbar 44 fixedly connected to the front link 230 of the leg extension unit 23, the motor slider 43 is pivotably connected to a rear crossbar 45, and the rear crossbar 45 is fixedly connected at both ends to the middle of the seat support 21 by means of intermediate links 46, respectively. Therefore, when the motor head 41 moves back and forth along the motor slide rail 42 relative to the motor slide block 43, the front cross bar 44 drives the leg stretching unit 230 to expand forwards or retract backwards through the front connecting piece 230.
The operation of the pendulum chair for changing between the sitting position and the lying position is explained below with reference to fig. 1 to 4.
In the sitting position as shown in fig. 1 and 2, the back support 22 is oriented generally vertically, the seat support 21 is oriented generally horizontally, the footrest support plate 234 is oriented generally vertically and the leg extension units 23 are fully stowed beneath the seat support 21; in the reclined position shown in figures 3 and 4, the leg units 23 are fully extended forward and the back rest 22 is fully reclined.
When the motor head 41 is operated in the forward direction, the position of the seat support 3 is kept substantially unchanged in the longitudinal direction due to the gravity of the user, the motor head 41 moves forward along the motor slide rail 42 relative to the motor slide block 43, so that the distance between the motor head 41 and the motor slide block 43 is increased, the front cross bar 44 drives the front connecting piece 230 to lift forward, and the leg stretching units 23 are completely unfolded from the folded state in the sitting position shown in fig. 1 and 2 to the unfolded state in the lying position shown in fig. 3 and 4. Meanwhile, as the leg stretching unit 23 is unfolded, the link 242 pivotally connected to the third leg 233 of the leg stretching unit 23 at the sixth pivot point F is moved forward accordingly, thereby moving the seventh pivot point G connecting the rear end of the link 242 and the backrest link 241 forward. Since the relative position between the seat support 21 and the transmission link 34 is fixed, the position of the backrest pivot point M remains substantially unchanged during the unfolding of the leg stretching unit 23, which brings the eighth pivot point H on the backrest link 241 to move downwards, thereby drawing the backrest support 22 to turn backwards and downwards around the backrest pivot point M. This allows the backrest support 22 to be tilted backwards while the leg extension unit 23 is extended forwards, so that the swing chair can be changed from the sitting position to the lying position.
From the lying position shown in fig. 3 and 4, if the motor head 41 runs in the reverse direction, the motor head 41 moves along the motor slide rail 42 toward the motor slider 43, so that the distance between the motor head 42 and the motor slider 43 is shortened, and the leg stretching unit 23 retracts backward, and further the linkage link 242 is driven to move backward and the seventh pivot point G of the backrest connecting member 241 is pushed to move backward. At the same time, also due to the fixed position of the backrest pivot point M, the eighth pivot point H on the backrest connection 241 moves upwards, which in turn pushes the backrest bracket 22 to flip upwards and forwards around the backrest pivot point. This allows the backrest support 22 to be tilted back to the front while the leg extension unit 23 is retracted back, so that the pendulum chair can be changed from the lying position to the sitting position.
In a preferred embodiment, as shown in fig. 3 to 5b, the swing chair has a swing limiting mechanism 25, which includes a first limiting member 251, a second limiting member 252, a chute limiting member 253, and a limiting link 254. The middle of the first limiting member 251 is pivotally connected to the transmission connecting rod 34 at a limiting pivot point K, a first limiting bushing 251a is disposed at the front end of the first limiting member 251, the rear end of the first limiting member 251 is pivotally connected to the front end of the second limiting member 252, and a second limiting bushing 252a is disposed at the rear end of the second limiting member 252. The sliding slot stopper 253 is fixedly connected to the transmission connecting rod 34 and extends upward from the transmission connecting rod to form a section with a stopping sliding slot 253a, and the second stopping bushing 252a is movably embedded in the swinging stopping sliding slot 253 a. One end of the limit link 254 is pivotally connected between the limit pivot point K of the first limiting member 251 and the first limit bushing 251a, and the other end thereof is pivotally connected to the link 242, so that the limit link 254 can be moved by the link 242, whereby the swing limit mechanism 25 can be switched between the swing release state and the swing limit state.
In the swing release state as shown in fig. 5a, the swing chair is in the sitting position, and the first and second check bushings 251a and 252a are not in contact with both the front and rear swing rods 32 and 33, thereby allowing forward and backward pivotal movement of the front and rear swing rods 32 and 33, so that the reclining mechanism 2 can swing forward and backward with respect to the base 1. When the swing chair is changed from the sitting position to the lying position, the leg stretching unit 23 is unfolded to cause the linkage link 242 to move forward, and the limit link 254 is also moved forward under the traction of the linkage link 242, so as to drive the first limit member 251 to pivot around the limit pivot point K, and move with the first limit bushing 251a thereof until the first limit bushing 251a abuts against the inner side of the front swing rod 32; at the same time, the rear end of the first limiting member 251 moves backward, so as to push the second limiting member 252 to move backward with its second limiting bushing 252a in the limiting chute 253a of the third limiting member 253 until the second limiting bushing 252a abuts against the inner side of the rear swing lever 33. This reaches the swing limit state shown in fig. 5b, and the pivoting of the forward and backward swing levers 32, 33 is prevented, so that the reclining mechanism 2 can no longer swing forward and backward with respect to the base 1.
An embodiment configured as a swing is shown in fig. 6-9. In place of the rocking mechanism in the rocking chair, the rocking chair includes a rocking mechanism capable of providing a rocking function, and for this purpose, a rocking base plate 31 'is used in place of the rocking base plate in the rocking mechanism, and the rocking base plate 31' is attached to the base 1 having the rocking function at its bottom. In the illustrated embodiment, the rocking base plate 31 'is mounted on a set of parallel extending ground-contacting supports 13 configured to be supported directly on the ground, with the drive links of the rocking mechanism being fixedly connected to the rocking base plate 31'. In this embodiment, the drive link consists of a substantially vertically extending first part 341 of the drive link and a substantially longitudinally extending second part 342 of the drive link, which are adjacent to the leg extension unit 23, but the drive link can also be constructed in one piece, as in the embodiment of the swing chair.
A support link 35 is likewise arranged between the drive link and the seat support 21, one end of the support link 35 being fixedly connected to the seat support 21 and the other end being fixedly connected to the drive link, in this embodiment to the second part 342 of the drive link. Thus, the rocking chair also ensures that the relative position between the seat support 21 and the transmission link is fixed during the transition between the sitting position and the lying position.
An eleventh pivot point L is additionally provided on the backrest link 241 between the seventh pivot point G and the ninth pivot point I. In this embodiment, the rocking mechanism further includes a first auxiliary link 36 and a second auxiliary link 37, wherein one end of the first auxiliary link 36 is pivotally connected to the backrest link 241 by an eleventh pivot point L. The second auxiliary link 37 is provided with an auxiliary bush 37a at one end thereof and the other end, which is not provided with an auxiliary bush, is pivotally connected to the transmission connecting rod, in this embodiment preferably pivotally connected to the transmission connecting rod second part 342. The other end of the first auxiliary connecting rod 36 is pivotally connected to the second auxiliary connecting rod 37 at an auxiliary pivot point N near its auxiliary bushing 37 a. The remaining technical features that are the same as those of the embodiment of fig. 1 to 4 are not described herein again.
Fig. 6 and 7 illustrate a configuration of the swing in a seating position, designed as a swing. As shown in fig. 6 and 7, the first auxiliary link 36 is pivotally connected to the second auxiliary link 37 via the auxiliary pivot point N, and at this time, the auxiliary bushing 37a at the end of the second auxiliary link 37 is spaced from the base 1, and in this embodiment, the ground-contacting bracket 13. In the lying position shown in fig. 8 and 9, the auxiliary bushing 37a rests against the base 1.
When the rocking chair is changed from the sitting position shown in fig. 6 and 7 to the lying position shown in fig. 8 and 9, the leg stretching unit 23 is driven by the electric actuating unit 4 to extend forward, thereby driving the linkage link 242 to move forward and further driving the backrest connecting member 241 to turn over, so that the seventh pivot point G on the backrest connecting member 241 moves forward, in which case the backrest bracket 22 is driven by the backrest connecting member 241 to turn over backward around the backrest pivot point M because the position of the backrest pivot point M relative to the transmission link remains fixed. At the same time, the eleventh pivot point L on the backrest link 241 is also moved forward, as one end of the second auxiliary link 37 is pivotally connected to the stationary transmission link, in this embodiment to the transmission link second part 342, pushing the auxiliary pivot point N between the first auxiliary link 36 and the second auxiliary link 37 downward and causing the second auxiliary link 37 to pivot downward with its end provided with the auxiliary bushing 37a about its pivot point on the transmission link second part 342 until the auxiliary bushing 37a abuts against the base 1, preferably against the ground-contacting bracket 13. In this embodiment, additional support of the back rest support in the reclined position is achieved by the secondary bushing 37a preventing the recliner mechanism 2 from swinging rearwardly in the reclined position, thereby preventing the risk of tipping over due to excessive recline of the back rest in the reclined position and ensuring safe use of the swing.
