Description

Vertical lifting sliding folding frame

Technical Field

The invention relates to the field of folding furniture design, in particular to a vertical lifting sliding folding frame.

Background

Furniture is an important daily life appliance, and the traditional furniture is usually formed by fixing a panel above four upright posts. With the acceleration of life rhythm of people and the restriction that the living space is smaller and smaller, the traditional furniture has the defects of inconvenient use and overlarge occupied area.

In recent years, folding furniture has been popular. A folding furniture (or folding frame) is a furniture that can be unfolded for conventional use when in use and folded up when in transportation or storage. For example: combination kitchens, service carts, work boards, art tables, garden carts, storage racks, and the like.

Although the conventional folding frame can be folded to a certain size, the conventional folding frame has a relatively heavy shape. In particular, the conventional folding frame has a large volume after being folded.

In addition, in current transportation, in order to reduce transportation cost, manufacturers can pack products in an uninstalled form into a container for transportation, but the existing packing forms pack all parts which are not installed compactly, so that the products can be transported in a compact manner, and transportation is facilitated. However, in this manner, the end user needs to assemble the transported furniture, which results in inconvenience in use.

Accordingly, there is a desire for a folding frame that can be transported and stored in a pre-installed and compact form and can be unfolded to a maximum size as furniture for a table or a car having a plurality of decks. In addition, it is desirable that the folding state and the unfolding state can be changed by a simple operation.

U.S. patent No. 6123207 discloses a transport shelf that is easily unfolded for storage, transport, and storage when in a display mode for display of an item, and folded for storage. The frame is provided with a pair of central support posts, and two side posts are respectively arranged at two sides of each central support post. A plurality of laminates are arranged between the side columns and the central support column, and when the shelf is in an unfolded state, the laminates are in a horizontal state. When the central support post is raised together with the side posts, the pivot axis of the deck is inclined. When the deck is substantially upright, the side posts are adjacent to the central support post, with the frame in a collapsed condition. The support can be in a reliable state under the supporting action of the central supporting column and the side columns. An elastic force equalizing system is arranged on one upright post and can support the mode conversion of the stand.

The folding frame uses two central support columns and four side columns to form a support structure, mode replacement between unfolding and folding of the whole frame is realized through an elasticity balancing system, and the defects of complex structure and complex parts exist.

In addition, U.S. patent No. 5131547 discloses a folding storage rack assembly comprising a plurality of upright, inverted U-shaped frame members in which hinged folding deck assemblies are disposed within the horizontally extending spaces of the rack members. With the cross beams as a support therebetween and a folding action, the storage rack can be easily and quickly opened so that the frame assemblies can be moved apart from each other. In use, the storage shelf may be simply folded up by moving the frame assemblies closer to each other so that the frame assemblies are brought together, while the shelf assemblies are folded up by the upward movement of the hinges.

However, in this patent, the frame folding can be realized by using the cross beams as the folding frame, but the structure is complicated and the components are complicated due to the existence of the cross beams.

See fig. 1, 2, 3.

The vertical lifting sliding folding frame provided by the embodiment mainly comprises a base 101, a first fixed upright 102, a second fixed upright 103, a sliding frame 104 and at least one panel 105. The specific connection relationship is as follows:

the first fixed upright post 102 and the second fixed upright post 103 are respectively fixed at two end portions of the base 101, a first guide rail (not shown in the figure, but not limited to, various guide rails capable of allowing other objects to slide along the guide rails) and a second guide rail (not shown in the figure, but not limited to, various guide rails capable of allowing other objects to slide along the guide rails) are respectively arranged at the inner sides of the first fixed upright post 102 and the second fixed upright post 103, the first guide rail and the second guide rail are opposite, the sliding frame 104 is arranged between the first guide rail and the second guide rail between the first fixed upright post 102 and the second fixed upright post 103, so that the sliding frame 104 can slide up and down along the first guide rail and the second guide rail in the first fixed upright post 102 and the second fixed upright post 103; the panel 105 is connected to the side of the sliding frame 104, and the panel 105 is connected to the sliding frame 104 at least at two points, so that each panel 105 can rotate on the vertical plane along the line formed by the connection point of the panel 105 and the sliding frame 104, and when the panel 105 rotates to the horizontal position, the panel 105 can be positioned in the horizontal position and be in the use state by some pin inserts or other fixing components.

In use, one can release the horizontally oriented members of the panel 105, raise the slide frame 104, and rotate the panel 105 down the side of the slide frame 104 until it is rotated to a stowed configuration vertically adjacent the slide frame 104. Positioning and locking devices can be arranged between the second fixed upright 102, the second fixed upright 103 or the sliding frame 104 and the panel 105, so that when the folding frame is folded, the positioning and locking devices are locked in a buckling mode, and the panel 105 is fixed on the side faces of the second fixed upright 102 and the second fixed upright 103.

When it is desired to open for use, the user can rotate the panel 105 to a horizontal position and hold it in the horizontal position while lowering the slide frame 104, with the folded frame in a fully open usable position.

As can be seen from the above, since the foldable frame of the present invention is provided with the liftable sliding frame, when the foldable frame is folded, the sliding frame 104 can be lifted to increase the height of the whole foldable frame, which is particularly suitable for the foldable furniture with the long length of the panel 105. Therefore, the structure of the embodiment breaks through the contradiction between the length of the panel and the use height of the folding frame in the prior art, so that the longer use panel can be arranged in the furniture with lower use height, and the folding frame has a smaller folding and packaging structure after being folded, thereby being beneficial to saving the transportation cost and being convenient to use.

It should be noted that, in the present embodiment, the connection between the panel 105 and the sliding frame 104 may be, but is not limited to, a hinge connection; in addition, the panel 105 may be integrated with the sliding frame 104, and the panel 105 may be rotated along a folding line of the sliding frame 104 (but is not limited to being made of rotatable plastic).

From the technical solution of this embodiment, a single-wing folding frame with a panel 105 only disposed on one side of the sliding frame 104 as shown in fig. 1, 2, and 3 may be designed by using the technical solution of this embodiment, a double-wing structure may also be formed by disposing a panel 105 on each of two sides of the sliding frame 104, and two or three panels 105 may also be disposed on one side of the sliding panel 105 according to actual needs so that the sliding panel 105 has multiple layers of panels 105 when in use.

Please refer to fig. 4, 5, and 6.

This embodiment provides a single-wing folding table using the structure of the present invention to form a liftable sliding folding frame, the table comprising: a first fixed upright 402 and a second fixed upright 403 are respectively vertically fixed on two end portions of a base 401, a first guide rail and a second guide rail mechanism are respectively fixed on inner sides of the first fixed upright 402 and the second fixed upright 403, a sliding frame 404 (the sliding frame 404 may be but is not limited to a sliding flat plate in this embodiment) is further connected between the first fixed upright 402 and the second fixed upright 403 through the first guide rail and the second guide rail, so that the sliding frame 404 can vertically slide along the first guide rail and the second guide rail mechanism in the first fixed upright 402 and the second fixed upright 403, a panel 405 is arranged on one side surface of the top of the sliding frame 404, and the panel 405 can rotate in a vertical plane along the connection portion between the panel 405 and the sliding frame 404. A movable upright 406 is further connected to the back of the panel 405, such that the movable upright 406 is opposite to the first fixed upright 402 and the second fixed upright 403, such that the movable upright 406 can rotate along the connection between the movable upright 406 and the panel 405, and when the panel 405 rotates to the horizontal, the movable upright 406 can touch the ground, and together with the first fixed upright 402 and the second fixed upright 403, the movable upright can support the horizontal panel 405.

Referring to fig. 5 and 6, when the table is not needed to be used, as shown in fig. 5 and 6, the sliding frame 404 can be lifted upwards, the movable upright posts 406 are separated from the ground, the panel 405 above the frame rotates downwards due to the loss of the support of the movable upright posts 406, when the sliding frame 404 is lifted to a certain height, the panel 405 is rotated to a vertical plane to be hung on the side of the sliding frame 404, as seen in fig. 6, the folding table is folded to a minimum state at the moment, the occupied space is the lowest, the storage is facilitated, the packing and the transportation are particularly facilitated, and the minimum transportation cost is ensured.

To further provide the folding table with greater stability, diagonal links 4071, 4072 are connected between the back of the top panel 405 and the base 401, and the diagonal links 4071, 4072 can pivot along the connection of the diagonal links 4071, 4072 to the base 401 and can pivot along the connection of the diagonal links 4071, 4072 to the back of the top panel 405. Therefore, when in use, the inclined supporting cross beam, the panel 405 and the sliding frame form a right triangle, and the supporting cross beam, the movable upright post 406 and the floor form a right triangle, so that the folding table has a stable supporting structure and is not easy to deform when in a fully unfolded state shown in fig. 4.

In addition, in order to further enable the table of the present embodiment to have a more stable supporting structure when in use, a cross link 408 may be connected between the movable upright post 406 and the sliding frame 104, and the cross link 408 may rotate along the connection between the cross link 408 and the movable upright post 406 and along the connection between the cross link 408 and the sliding frame 104. When the foldable table is unfolded to the fully unfolded state shown in fig. 4, the cross link 408 further forms a triangle with the movable upright 406 and the inclined links 4071 and 4072, which further plays a role of fixing the movable upright 406, and is further beneficial to improving the support stability of the foldable table in the unfolded state.

It should be noted that, in this embodiment, in order to make the folding of this folding frame smoother and the linkage is better, it is preferable to perform the following design:

when setting up the connection of horizontal connecting rod, activity stand, sliding frame for:

when the bottom of the movable upright 406 is horizontal to the bottom of the base 401, the horizontal height of the first connection point is lower than that of the second connection point, wherein the first connection point is: the connection point of the cross link 408 and the movable upright 406 is: the present cross link 408 is connected to the sliding frame 404.

Thus, during the folding of the frame, the operator only needs to slightly and forcefully lift the panel 105 upward at the top edge thereof, and since the level of the second connecting point is higher than that of the first connecting point, the transverse link 408 exerts an upward force on the sliding frame 404 due to inertia, and the movable upright 406 is linked with the other end of the transverse link 408. Therefore, the folding force of the user is reduced, and the operation is simpler and more labor-saving.

Referring to fig. 4, 5, and 6, in order to easily install the cross link 408, the movable upright 406 may be configured to have a gap at the connection position of the cross link 408, and the cross link 408 may be installed at the gap, where the installation manner is favorable for ensuring the smoothness of the movement of the cross link 408.

In addition, the connection of the rotatable parts in the present embodiment may be, but not limited to, various hinge connections in the related art, and may be others.

In folding the table as shown in fig. 5 and 6, the inclined links 4071, 4072 are rotated inward along with the top panel 405, and when the sliding frame 404 is lifted to the highest position and the top panel 405 is hung on the side of the sliding frame 404, the inclined links 4071, 4072 are rotated to the upright position, thereby minimizing the volume after folding.

In the process of folding the table as shown in fig. 5 and 6, one end of the transverse connecting rod 408 rises along with the sliding panel 405, and is driven by the end to pull the panel 405 to rotate, so that the whole folding action is smoother and the operation is easy; also during the unfolding process, the cross link 408 also functions to link the movement between the sliding frame 404 and the panel 405, so that the unfolding of the components is smooth and complete in one go during the whole unfolding process. In summary, the design of the cross link 408 is not only beneficial to strengthen the supporting structure of the folding frame in the fully unfolded state, but also beneficial to improve the smoothness of the folding movement of the folding frame, so that the folding operation of the user is more flexible.
