Description

Technical Field

[0001] The utility model belongs to the field of furniture, and in particular relates to a multi-size folding table with a stable structure. Background Art

[0002] Existing folding tables with various adjustable sizes usually have a middle table top hinged to multiple side table tops, and then abutment members are provided to abut against both the middle table top and the side table top to fix the side table top in the open position, while the table legs are fixedly connected or hinged to the middle table top.

[0003] When the side table panel is subjected to force, the fulcrum at which the force acts on the side table panel is the hinge between the middle table panel and the side table panel, and the lever arm is relatively long, causing the side table panel, the hinges between the side table panel and the middle table panel, the abutments, etc. to be easily deformed, making the fixation of the side table panel not stable enough and having a shorter service life.

[0004] In order to solve the above technical problems, those skilled in the art may consider setting the table legs on the side table panels, but this setting will inevitably make the side table panels unable to fold, or the folding table cannot realize its function as a table after the side table panels are folded. Utility Model Content

[0005] One of the purposes of the utility model is to overcome the defects of the prior art and provide a multi-size folding table with a stable structure.

[0006] The technical solution of the utility model is as follows:

[0007] A multi-size folding table with a stable structure comprises a table top and four sets of table leg assemblies, wherein the table top comprises a middle table top and two side table tops, wherein both ends of the middle table top in the length direction of the table top are respectively hinged to one side table top, and the side table tops are rotated to realize opening or folding of the side table tops;

[0008] The bottom surface of the table top is provided with guide members, each set of guide members is connected to a table leg assembly, and the table leg assembly moves back and forth in the length direction of the table top under the restriction of the guide members;

[0009] The table leg assembly comprises supporting legs for supporting the table board. When the side table boards are in the open position, the supporting legs slide under the side table boards. When the side table boards are in the folded position, the supporting legs slide under the middle table boards.

[0010] In some possible implementations, the table leg assembly includes a support leg, a side support member and a slide bar, the end of the support leg and the end of the side support member are respectively hinged to the slide bar, the side support member is provided with a slide groove along its length direction, the support leg is correspondingly provided with a slide block, the slide block is in the slide groove and can be relatively displaced along the length direction of the side support member, and the support leg is propped up or folded;

[0011] In some possible implementations, the guide member includes at least one guide tube arranged along the length direction of the table top, the sliding rod is sleeved with at least one guide tube, and the table leg assembly slides relatively in the length direction of the table top through the cooperation between the sliding rod and the guide tube.

[0012] In some possible implementations, a stopper is further provided at one end of the guide member away from the center of the table top, and the distance between the stopper and the adjacent guide tube is less than the length of the slide rod;

[0013] When the table leg assembly slides to the farthest position in the direction away from the middle table board, the slide rod abuts against the stopper.

[0014] In some possible implementations, the stopper is disposed on the bottom surface of the side table board.

[0015] In some possible implementations, one end of the slide bar away from the center of the table top is a hinged end, and the support leg and the side support member are hingedly connected at the hinged end;

[0016] The guide tube is arranged on the bottom surface of the middle table board and the hinged end is located between the stopper and the guide tube adjacent to the stopper.

[0017] In some possible implementations, the supporting legs are connected via a connecting rod, and the connecting rod and two supporting legs connected to the connecting rod form an H-shaped supporting leg.

[0018] In some possible implementations, a table leg slot is provided on the side of the side table board away from the middle table board. When the side table board is rotated inward to abut against the H-shaped support leg, the H-shaped support leg is engaged in the table leg slot.

[0019] In some possible implementations, the length of the side table panel is half the length of the middle table panel.

[0020] In some possible implementations, the guide tube and the slide rod are interference fit.

[0021] The utility model provides a multi-size folding table with a stable structure, which has a table leg assembly that can slide along the length direction of the table board. When the side table board is opened, the table leg assembly can slide to the bottom surface of the side table board, and when the side table board is folded, the table leg assembly can slide to the bottom surface of the middle table board. This technical solution can reduce the influence of the force on the side table board of the folding table on the side table board and the hinge between the side table board and the middle table board, thereby increasing the stability of the structure.

[0022] In addition, in some preferred implementations, when the table leg assembly slides to the side table panel, the sliding rod abuts against the side table panel and the middle table panel at the same time, and the sliding rod, the supporting legs, and the hinges between the side table panel and the middle table panel cooperate to stably fix the side table panel in its open position.

DETAILED DESCRIPTION

[0033] 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 a central 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 a central element at the same time. In the present utility model, 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. It is only for the purpose of simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the present utility model. For example, the "length direction" and the "width direction" are only two directions perpendicular to each other, but the size of the table top in its "length direction" can be greater than, equal to or less than its size in the "width direction".

[0034] The side table panel "opened" in this article means that the upper surface of the side table panel and the upper surface of the middle table panel are located in the same plane; and the side table panel "folded" means that the side table panel is not in the "open" position. At this time, compared with the open position, the side table panel is rotated inward along the hinge point between the side table panel and the middle table panel (i.e., in the direction close to the bottom surface of the middle table panel) by 0-180° (excluding 0°). When the side table panel is rotated 180°, the middle table panel and the side table panel overlap, which can minimize the storage space required for the folding table when it is not in use. The "bottom surface" of the table panel, middle table panel and side table panel in this article refers to the downward side of the table panel, middle table panel and side table panel when the multi-sized folding table is placed upright and the side table panel is in its open position.

[0035] The table leg assembly can slide between its "closest position" and "farthest position", and the "farthest position" refers to the farthest position that can be reached after the slide rod drives the support leg and the side support to slide away from the middle table board, and vice versa.

[0036] The technical solution of the present invention is clearly and completely described below in conjunction with the accompanying drawings of the present invention; it is obvious that the embodiment described above is only one implementation method of the present invention, and all other embodiments obtained by ordinary technicians in this field without making creative work based on the following embodiments belong to the protection scope of the present invention.

[0037] like Figure 1-Figure 9 As shown, the multi-size folding table includes a table top 1 and a table leg assembly 2. Figure 3As shown, the table leg assembly 2 includes a supporting leg 21, a side supporting member 22 and a sliding rod 23. The supporting leg 21 and the side supporting member 22 are hinged to the sliding rod 23 at the ends respectively. The side supporting member 22 is provided with a sliding groove 221 along its length direction. The supporting leg 21 is provided with a limiting slider 211. The limiting slider 211 is clamped with the sliding groove 221 and can be relatively displaced along the length direction of the side supporting member 22 to realize the opening or folding of the table leg assembly 2.

[0038] The table top 1 is formed by hingedly connecting a middle table top 11 and two side table tops 12. Specifically, each side table top 12 is hingedly connected to the middle table top 11 through two hinge points 14. The hinge points 14 are arranged below the middle table top 11 and the side table top 12. When the side table top 12 is in the open position, Figure 1 and Figure 2 As shown, one side of the side table board 12 abuts against one side of the middle table board 11, limiting the side table board 12 from further rotating upward in the open position. The side table board 12 can rotate inward 0-180° with the hinge axis between the middle table board 11 and the side table board 12 as the rotation axis. By opening or folding the two side table boards 12 respectively, the table board 1 can achieve three different usage size changes. In this embodiment, as Figure 8 and Fig. 9 As shown, the size of the middle table panel 11 in the length direction of the table panel 1 is twice that of the side table panel 12. When the two side table panels 12 are rotated 180° inward from their open positions, the two side table panels 12 overlap with the middle table panel 11 and the table leg assembly 2 is folded and stored between the side table panel 12 and the middle table panel 11.

[0039] Four groups of guide members are symmetrically arranged on the bottom surface of the table top 1, and the guide members include a guide tube 131 coaxially arranged on the bottom surface of the middle table top 11 along the length direction of the table top 1, and a stopper 132 arranged on the bottom surface of the side table top 12, and the stopper 132 is arranged on the extension line of the guide tube 131. The distance between the stopper 132 and the adjacent guide tube 131 in a group of guide members is less than the length of the slide bar 23.

[0040] The slide bar 23 is sleeved with at least one guide tube 131, and the table leg assembly 2 slides relatively in the length direction of the table top 1 through the cooperation between the slide bar 23 and the guide tube 131. Figure 1 As shown in the figure, when the table leg assembly 2 slides to the farthest position in the direction away from the middle table board 11, the slide bar 23 abuts against the stopper 132. Furthermore, the end of the slide bar 23 away from the center of the table board 1 is a hinge end 231, the support leg 21 and the slide bar 23 are hinged at the hinge end 231, and the hinge end 231 is located between the stopper 132 and the guide tube 131 adjacent to the stopper 132. When the table leg assembly 2 slides to the nearest position in the direction close to the middle table board 11, as shown in the figure, the table leg assembly 2 slides to the farthest position in the direction away from the middle table board 11, as shown in the figure, the slide bar 23 abuts against the stopper 132. Furthermore, the end of the slide bar 23 away from the center of the table board 1 is a hinge end 231, the support leg 21 and the slide bar 23 are hinged at the hinge end 231, and the hinge end 231 is located between the stopper 132 and the guide tube 131 adjacent to the stopper 132. Figure 5As shown, the side support member 22 abuts against the guide tube 131 adjacent to the stopper 132. In addition, the slide bar 23 and the guide tube 131 sleeved with the slide bar 23 are interference-fitted, so that during the sliding process of the slide bar 23, the table leg assembly 2 can be kept at any position between its nearest position and its farthest position by being tightly sleeved with the guide tube 131.

[0041] When the side table 12 is in the open position ( Figure 1 and Figure 2 ), the user slides the table leg assembly 2 so that at least part of it is located under the side table board 12. At this time, the slide bar 23 abuts against the side table board 12 and the middle table board 11 at the same time, and plays a role in fixing the open position of the side table board 12. At the same time, because the support leg 21 is arranged under the side table board 12 under the guidance of the slide bar 23, the distance between the edge of the side table board 12 away from the middle table board 11 and the support leg 21 is reduced. When the edge of the side table board 12 away from the middle table board 11 is stressed, the side table board 12 is less likely to be deformed, and the hinge between the side table board 12 and the middle table board 11 is more stable.

[0042] Furthermore, in this embodiment, the support legs 21 of the two table leg assemblies 2 arranged on the same side along the width direction of the table board 1 are connected by a connecting rod 24, and the connecting rod 24 and the two support legs 21 connected to the connecting rod 24 form an H-shaped support leg 21. The side of the side table board 12 away from the middle table board 11 is provided with a table leg slot 121, such as Figure 2-Figure 7 As shown, when the side table board 12 rotates inwards to abut against the H-shaped support leg 21 , the H-shaped support leg 21 is engaged in the table leg slot 121 .

[0043] In addition, a reinforcing rib 111 is provided on the bottom surface of the middle table top 11 along the length direction of the table top 1 .
