DETAILED DESCRIPTION

[0028] Example 1

[0029] See also Figures 1 to 3 As shown, a folding structure of a table and chair of the utility model comprises a panel 1 , at least one supporting part 2 is hinged at the bottom of the panel 1 , and at least one movable leg 3 is provided on the supporting part 2 .

[0030] In the initial state, the panel 1 and the movable legs 3 are respectively rotated and folded relative to the support part 2 to be flat; when in use, the movable legs 3 are rotated and opened relative to the support part 2 and cooperate with the support part 2 to form a support frame for the panel 1.

[0031] In this embodiment, a support portion 2 is hingedly connected to the bottom of the panel 1 in a horizontal direction, and a movable leg 3 is hingedly connected to the support portion 2 in a vertical direction.

[0032] In the initial state, the panel 1 and the movable legs 3 are respectively rotated and folded relative to the support part 2 to form a flat shape; when in use, the movable legs 3 are rotated and opened relative to the support part 2 and cooperate with the support part 2 to form a triangular support frame of the panel 1.

[0033] Preferably, a tubular hinge seat 4 is horizontally arranged at the bottom of the panel 1; the support portion 2 includes a rotating shaft 5 passing through the hinge seat 4, and an L-shaped first leg 6 is arranged at one end of the rotating shaft 5.

[0034] An L-shaped connecting rod 7 is arranged at the other end of the rotating shaft 5 , and the movable leg 3 is rotatably connected to the free end of the connecting rod 7 .

[0035] Of course, based on this concept, the hinge seat and the rotating shaft can also be fixedly connected, and correspondingly, the connecting rod and the rotating shaft can be movably connected, which can achieve the same function and have no significant difference in appearance. This is an equivalent alternative solution that can be easily thought of by technical personnel in this field.

[0036] In this embodiment, the movable leg 3 includes a second leg 3a rotatably connected to the connecting rod 7, and the second leg 3a is connected to the third leg 3c through a transverse connecting rod 3b; a limiting structure matched with the third leg 3c is provided at the bottom of the panel 1. The first leg and the second leg are always in a parallel state.

[0037] Preferably, when in the folded state, the third leg 3c is located below the shaft 5, and the support portion 2 and the movable leg 3 overlap and are close to the panel 1. The overlap mentioned here means that the support portion and the movable leg overlap when viewed in the direction parallel to the panel, so that the entire table and chair structure can be folded to the thinnest state, occupying less space.

[0038] Preferably, in this embodiment, the limiting structure includes a connection seat 8 vertically arranged at the bottom of the panel 1, a connection column 8a is arranged at the free end of the connection seat 8, and a rubber sleeve 9 matched with the connection column 8a is arranged at the upper end of the third leg 3c; when the third leg 3c is rotated into place and connected with the panel, the connection column 8a is located in the rubber sleeve 9. Of course, the limiting structure can also adopt other conventional assembly structures in the field, as long as the third leg can be positioned and the third leg can be connected with the panel with a certain strength in the open state and will not be easily separated. For example, the same function can be achieved by using the combination of elastic pins and positioning holes.

[0039] Further preferably, the connecting rod 7 is composed of a horizontal connecting portion 7a connected to the rotating shaft 5, a vertical connecting seat 7b fixed to the free end of the horizontal connecting portion 7a, and a vertical connecting portion 7c fixedly connected to the vertical connecting seat 7b.

[0040] The upper end of the second leg 3a is tubular and sleeved on the vertical connection part 7c. An elongated limiting hole 3d is radially arranged at the proximal end of the upper end of the second leg 3a. A limiting column 7d matching the elongated limiting hole 3d is arranged on the vertical connection seat 7b.

[0041] In short, the connecting rod is L-shaped. Based on the concept of the utility model, it can also be an integrally formed structure. At the same time, when the rotating shaft and the hinge seat are rotatably connected, the connecting rod and the rotating shaft can also be fixedly connected or integrally formed. In this embodiment, the panel is a stool surface. Since the panel is small, the connecting rod and the rotating shaft are directly fixed into one.

[0042] In this embodiment, the panel is a metal panel used as a folding stool, and the hinge seat and the connecting seat are welded to the bottom of the panel.

[0043] Example 2

[0044] See also Figure 4 As shown, a folding table and chair structure of the utility model has a structure that is basically the same as that of embodiment 1, except that the panel is made of non-metallic material, and the hinge seat and the connecting seat are fixed to the bottom of the panel by screws. The use effect is the same.

[0045] Example 3

[0046] See also Figure 5 and Figure 6 As shown, a table and chair folding structure of the utility model has a structure that is basically the same as that of Example 1, except that it is a folding table with a larger overall size. At the same time, the hinge seat is also relatively long to improve stability.

[0047] Example 4

[0048] See also Figure 7 As shown, a table and chair folding structure of the utility model has a structure that is basically the same as that of Example 1, except that the panel 1 is in a long strip shape, and a support portion 2 is hinged horizontally at the bottom of one side of the long side of the panel 1, and at least two movable legs 3 are hinged vertically on the support portion 2, and the movable legs 3 are arranged at intervals along the length direction of the support portion 2.

[0049] In the initial state, the panel 1 and the movable legs 3 are respectively rotated and folded relative to the support part 2 to be flat; when in use, the movable legs 3 are rotated and opened relative to the support part 2 and cooperate with the support part 2 to form a support frame for the panel 1.

[0050] In this embodiment, movable legs 3 are respectively hinged vertically at both ends of the support portion 2 , and the two movable legs 3 are symmetrically arranged along the support portion 2 .

[0051] Preferably, a tubular hinge seat 4 is horizontally arranged at the bottom of the panel 1; the support part 2 includes a rotating shaft 5 passing through the hinge seat 4, and L-shaped connecting rods 7 are symmetrically arranged at both ends of the rotating shaft 5; each movable leg 3 is rotatably connected to the corresponding free end of the connecting rod 7.

[0052] The above embodiments are preferred implementation modes of the present invention and are only used to facilitate the explanation of the present invention. They are not intended to limit the present invention in any form. Any person with ordinary knowledge in the relevant technical field, if they do not depart from the scope of the technical features of the present invention, can make equivalent embodiments by partial changes or modifications to the technical contents disclosed in the present invention, and they still fall within the scope of the technical features of the present invention without departing from the technical features of the present invention.
