Description

A folding load-bearing furniture designed to prevent hand pinching

[0001] Cross-references to related applications

[0002] This application claims priority to and is based on Chinese Patent Application No. 2024209780953, filed with the China National Intellectual Property Administration on May 8, 2024, entitled "A Folding Load-bearing Furniture with Anti-Pinch Hands", the contents of which are incorporated herein by reference. Technical Field

[0003] This invention belongs to the field of furniture, specifically relating to a foldable load-bearing furniture designed to prevent hand pinching. Background Technology

[0004] Load-bearing furniture refers to furniture with a load-bearing surface that can be used to place people or objects, such as tables and chairs. One structure of load-bearing furniture includes a load-bearing panel and two X-shaped supports symmetrically arranged on both sides of the load-bearing panel. The X-shaped supports include front legs and rear legs that are rotatably hinged. The front or rear legs can slide back and forth along the load-bearing panel to achieve folding of the load-bearing furniture, which has the advantages of simple structure and convenient storage.

[0005] However, in order to fold the load-bearing furniture, users usually need to hold the front or back leg with one hand and rotate the load-bearing surface with the other hand to bring it close to the X-shaped bracket and move the front and back legs closer to each other. The user's hand holding the front or back leg is likely to get caught in the folding process, resulting in poor usability and safety. Summary of the Invention

[0006] One of the objectives of this invention is to overcome the deficiencies of the prior art and provide a foldable load-bearing furniture that prevents hand pinching.

[0007] The technical solution of the present invention is as follows:

[0008] A folding support furniture with anti-pinch function includes a support panel and two X-shaped supports symmetrically arranged on the left and right sides of the support panel. The X-shaped supports include front legs and rear legs that are rotatably hinged. The upper end of the rear leg is hinged to the bottom surface of the support panel. The upper ends of the two front legs are respectively connected to the left and right sides of the support panel through sliding connection components and slide back and forth along the left and right sides of the support panel. The upper ends of the two front legs extend upward and connect to form a handle.

[0009] In some possible implementations, the sliding connection assembly includes a sliding guide rail and a slide block slidably disposed on the sliding guide rail, the sliding guide rail being disposed along the left and right sides of the support panel, and the slide block being rotatably hinged to the upper end of the front leg.

[0010] In some possible implementations, the distance between the upper end of the hind leg and the front side of the bearing surface is less than the height of the handle.

[0011] In some possible implementations, the sliding connection component also includes a stop block disposed at the rear end of the sliding guide rail. When the slide block slides to the rear end of the sliding guide rail, the slide block abuts against the stop block.

[0012] In some possible implementations, the slide has a locking part and a hinge part disposed below the locking part, the locking part being sleeved with the sliding guide rail, and the hinge part being rotatably hinged to the upper end of the front leg.

[0013] In some possible implementations, the width of the upper end of the rear leg gradually decreases from bottom to top in the width direction of the folding load-bearing furniture, and the hinge is located between the upper ends of the front leg and the rear leg when the folding load-bearing furniture is folded.

[0014] In some possible implementations, the rear side of the supporting panel extends upward to form a enclosure.

[0015] In some possible implementations, the support panel includes a metal reinforcing tube disposed around the circumference.

[0016] In some possible implementations, the distance between the two front legs is greater than the width of the support panel.

[0017] In some possible implementations, the two hind legs are connected by a crossbar.

[0018] In this invention, the upper end of the front leg of the folding support furniture extends to form a handle. By grasping the handle and the front end of the support panel, and then moving the handle towards the front end of the support panel, the upper end of the front leg slides forward along the sliding guide rail, thereby realizing the folding of the folding support furniture. During this process, there is no need to place the hand on the part of the X-shaped bracket below the support panel, so there is no problem of pinching the hand during the process of the angle between the front leg and the rear leg decreasing, which has high safety and good user experience.

Detailed Implementation

[0029] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there may be an intervening element. When an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. In this invention, the terms "upper," "lower," "bottom," "rear," "side," "length direction," and "width direction," etc., indicate orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, and are only for the purpose of simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. In the following embodiments, "width" refers to the distance between the left and right sides of the supporting panel.

[0030] As shown in Figures 1 and 4, this application provides a folding support furniture that prevents hand pinching. In this embodiment, the folding support furniture is a folding table.

[0031] Specifically, the folding support furniture includes a support panel 1, two X-shaped supports 2, two sets of sliding components, and a crossbar 221. The two X-shaped supports 2 are symmetrically arranged on the left and right sides of the support panel 1. Each X-shaped support 2 includes a front leg 21 and a rear leg 22 that are hinged together. The upper end of the rear leg 22 is hinged to the bottom surface of the support panel 1, and the two rear legs 22 are connected by a crossbar 221. The upper ends of the two front legs 21 are slidably connected to the left and right sides of the support panel 1 via sliding components and can move back and forth relative to the support panel 1. The upper ends of the two front legs 21 extend upwards and connect to form a handle 211.

[0032] Figures 2 and 3 illustrate the connection relationship between the support panel 1, the sliding assembly, and the front leg 21. First, the sliding assembly includes a sliding guide rail 31, a slide block 32, and a stop block 33. The sliding guide rail 31 is located on the left and right sides of the support panel 1, and its vertical height is greater than the height of the main body of the support panel 1. The slide block 32 engages with the sliding guide rail 31 and can slide back and forth along the sliding guide rail 31, thereby moving the front leg 21 back and forth relative to the support panel 1. Further, as shown in Figure 2, the slide block 32 includes a engaging portion 321 and a hinge portion 322 located below the engaging portion 321. The slide block 32 engages with the sliding guide rail 31 via the engaging portion 321 and is rotatably hinged to the front leg 21 via the hinge portion 322. The stop block 33 is located at the rear end of the sliding guide rail 31. When the folding chair is opened, the slide block 32 slides to the rear end of the sliding guide rail 31 and abuts against the stop block 33.

[0033] Referring to Figures 1, 2, and 3, it can be seen that the rear side of the support panel 1 extends upward to form a barrier 11. In this embodiment, the barrier 11 and the blocking block 33 are integrally formed. The barrier 11, the blocking block 33, and the sliding guide rail 31 protrude upward relative to the main body of the support panel 1, which can prevent objects placed on the support panel 1 from falling off from the left, right, or rear side of the support panel 1 to a certain extent. In this embodiment, the support panel 31 includes an upper panel 311 and a lower base plate 312. A sliding guide rail 31 is formed on the side of the upper panel 311, and a metal reinforcing tube 12 is provided inside the side. The upper panel 311 and the lower base plate are plastic parts, preferably vacuum-formed parts.

[0034] Figure 4 is a schematic diagram of the folding support furniture when opened and inverted. As can be seen from Figures 4 and 5, the upper end of the rear leg 22 is hinged to the bottom surface of the support panel 1. As shown in Figures 4-9, the width of the upper end of the rear leg 22 gradually decreases from bottom to top in the width direction of the folding support furniture. Figure 9 is a rear view of the folding support furniture in the folded state. When the folding support furniture is folded, the hinge 322 is located between the upper ends of the front leg 21 and the rear leg 22.

[0035] Figure 1 is a schematic diagram of the folding support furniture in the open state. In this state, the X-shaped support 2 is open, and the slide 32 is located at the rear end of the sliding guide rail 31 and abuts against the stop block 33. At this time, the user can grasp the handle 211 and the front end of the support panel 1, bringing the handle 211 closer to the front end of the support panel 1. During this process, the handle 211 drives the front leg 21 and the rear leg 22 to rotate relative to each other until the X-shaped support 2 folds. The slide 32 slides away from the stop block 33 on the sliding guide rail 31, and the support panel 1 rotates downwards along the hinge point between the support panel 1 and the rear leg 22. Figures 8 and 9 are schematic diagrams of the folding support furniture in the folded state. It can be seen that the front leg 21 and the rear leg 22 are on the same plane, the support panel 1, the front leg 21, and the rear leg 22 are approximately parallel, the slide 32 is located at the end of the sliding guide rail 31 away from the stop block 33, and the hinge part 322 of the slide 32 is located between the front leg 21 and the rear leg 22.
