Piece of Foldable Load-Bearing Furniture with Anti-Pinch Function

This application claims priority to Chinese patent application number 202420978095.3, filed on May 8, 2024. Chinese patent application number 202420978095.3 is incorporated herein by reference.

The present disclosure relates to the field of furniture and in particular to a piece of foldable load-bearing furniture with an anti-pinch function.

Load-bearing furniture refers to furniture with a bearing surface designed to support people or objects, such as tables and chairs. One common structure of such furniture comprises a bearing panel and two X-shaped supporting frames symmetrically arranged on two sides of the bearing panel. Each of the two X-shaped supporting frames comprises a front leg and a rear leg pivotally connected to each other, allowing the front leg or the rear leg to slide forward and backward along the bearing panel to facilitate folding. This design offers advantages such as a simple structure and convenient storage.

However, to fold the furniture, users typically need to grip either the front leg or the rear leg with one hand while using the other hand to rotate the bearing panel toward the two X-shaped supporting frames, bringing the front legs and the rear legs closer together. During this process, the hand holding the front leg or the rear leg is at risk of being pinched, resulting in poor user experience and safety concerns.

The technical problem to be solved by the present disclosure is to provide a piece of foldable load-bearing furniture with an anti-pinch function.

In order to solve the above technical problems, the present disclosure provides a piece of foldable load-bearing furniture with an anti-pinch function comprising a load-bearing panel and two X-shaped supporting frames symmetrically arranged on a left side and a right side of the load-bearing panel. Each of the two X-shaped supporting frames comprises a front leg and a rear leg which are pivotally connected to each other, and an upper end of the rear leg is pivotally connected to a bottom surface of the load-bearing panel. Upper ends of the front legs are respectively slidably connected to the left side and the right side of the load-bearing panel through a corresponding one of two sliding assemblies and are configured to move forward and backward along the left side and the right side of the load-bearing panel. The upper ends of the front legs extend upward and are connected to each other to form a handle.

In some possible implementations, each of the two sliding assemblies comprises a sliding rail and a sliding seat slidably disposed on the sliding rail, and the sliding rails are arranged along the left side and the right side of the load-bearing panel. The sliding seat is pivotally connected to the upper end of the front leg of a corresponding one of the two X-shaped supporting frames.

In some possible implementations, a distance between the upper end of the rear leg and a front side of the load-bearing panel is smaller than a height of the handle.

In some possible implementations, each of the two sliding assemblies comprises a position-stopping block, and the position-stopping block is disposed at a rear end of the sliding rail. When the sliding seat slides to correspond to the rear end of the sliding rail, the sliding seat abuts the position-stopping block.

In some possible implementations, the sliding seat comprises a buckling portion and a pivoting portion located below the buckling portion, and the buckling portion is sleeved on the sliding rail. The pivoting portion is pivotally connected to the upper end of the front leg of the corresponding one of the two X-shaped supporting frames.

In some possible implementations, a width of the upper end of the rear leg in a width direction of the piece of foldable load-bearing furniture gradually decreases from bottom to top. When the piece of foldable load-bearing furniture is folded, the pivoting portion is located between the upper end of the front leg and the upper end of the rear leg of the corresponding one of the two X-shaped supporting frames.

In some possible implementations, a rear side of the load-bearing panel extends upward to form a baffle.

In some possible implementations, a metal reinforcement tube is provided along a circumferential side of the load-bearing panel.

In some possible implementations, a distance between the front legs is greater than a width of the load-bearing panel.

In some possible implementations, the rear legs are connected to each other by a lateral rod.

In the present disclosure, the upper ends of the front legs of the piece of foldable load-bearing furniture are extended to form the handle. By gripping the handle and the front side of the load-bearing panel, then moving the handle toward the front side of the load-bearing panel, the upper end of the front legs slide forward along the sliding rail, enabling the folding of the piece of foldable load-bearing furniture. Since this operation does not require placing hands in an area below the load-bearing panel where the two X-shaped supporting frames are located, a risk of pinching fingers during a reduction of an angle between the front legs and the rear legs is eliminated. This design significantly improves safety and enhances user experience.

It should be noted that when an element is referred to as being “fixed to” another element, it may be directly on the other element or there may also be an intervening element. When an element is considered to be “connected” to another element, it may be directly connected to the other element or there may be an intervening element. In the present disclosure, the terms“upper”, “lower”, “bottom”, “back”, “side”, “length direction”, and “width direction” indicate that the orientation or position relationship is based on the orientation or position relationship shown in the accompanying drawings, which is only for simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation or must be constructed and operated in a specific orientation, and therefore should not be understood as a limitation to the present disclosure. In the following embodiments, “width” refers to the distance between the left side and the right side of the load-bearing panel.

As shown inand, the present application provides a piece of foldable load-bearing furniture with an anti-pinch function. In the present embodiment, the piece of foldable load-bearing furniture is a folding table.

Specifically, the piece of foldable load-bearing furniture comprises a load-bearing panel, two X-shaped supporting frames, two sliding assemblies, and a lateral rod. The two X-shaped supporting framesare symmetrically arranged on a left side and a right side of the load-bearing panel, and each of the two X-shaped supporting framescomprises a front legand a rear legwhich are pivotally connected to each other. An upper end of the rear legis pivotally connected to a bottom surface of the load-bearing panel, and the rear legsare connected to each other by the lateral rod. Upper ends of the front legsare respectively slidably connected to the left side and the right side of the load-bearing panelthrough the two sliding assemblies and are configured to move forward and backward relative to the load-bearing panel. The upper ends of the front legsextend upward and are connected to each other to form a handle.
