Please refer to FIG. 1 , which is a folding chair provided by the present invention, which mainly comprises a side frame 1 and a plurality of connecting members 21A, 21B, 22 (21B not shown) and a seat pad 3, wherein the connecting piece 21, 22 and the seat cushion 3 can be folded, and the utility model can reduce the occupied volume and facilitate storage. The structure of the detail of the present invention is as follows.
First define a coordinate system with three-dimensional orientation for illustration. The three-dimensional directions are respectively the X direction, the Y direction, and the Z direction, wherein the three directions are perpendicular to each other, and the X direction and the Y direction respectively define the longitudinal and lateral directions on the same height plane, and the Z direction is the height direction. As shown in the first and second figures, the two side frames 1 are spaced apart from each other in the X direction, and each of the side frames 1 has a first support portion 11 having a first direction in the Y direction. The front end 111 and the rear end 112 are respectively provided with support columns 12 extending in the -Z direction at the front end 111 and the rear end 112. The side frames 1 project a second support portion 13 in the +Z direction at the rear end 112 of the first support portion 11.
A plurality of connecting members are disposed between the two side frames 1 , wherein a part of the connecting members are disposed on the first supporting portion 11 of the two side frames 1 , and a part of the connecting members are disposed on the second supporting portion 13 of the two side frames 1 . on. In this embodiment, a connecting member 21A is disposed at the front end 111 of the two first supporting portions 11, and a connecting member 21B is disposed at the rear end 112 of the two first supporting portions 11, thereby forming a supporting structure standing on the ground. And a connecting member 22 is disposed on the two second supporting portions 13 to form a backrest.
The connecting members 21A, 21B, and 22 are respectively pivotally connected by the two first combining portions 23; in detail, the two first combining portions 23 are plate-shaped, and are pivotally connected to each other by one adjacent side, and are defined A first fold line 24 extending in the Z direction is formed at the pivotal joint. Accordingly, the first connecting portions 23 are pivoted relative to each other by the first folding line 24, so that the connecting members 21A, 21B, and 22 can be folded, and the connecting members 21A, 21B, and 22 are formed into a flat shape. Change to a fold. On the other hand, each of the connecting members 21A, 21B, and 22 is pivotally provided on the side frame 1 by the two first combining portions 23 one by one.
A seat pad 3 is further disposed between the two side frames 1 , wherein the seat pad 3 is pivotally connected by two second combination portions 31; in detail, the two second combination portions 31 are plate-shaped and adjacent to each other. A second fold line 32 extending in the Y direction is formed at one end of the pivotal connection. Accordingly, the two second combining portions 31 are pivoted relative to each other with the second folding line 32 as an axis, so that the cushion plate 3 can be folded, and the cushion plate 3 is converted into a folded shape by a flat plate shape.
On the other hand, the two second assembly portions 31 of the seat cushion 3 are respectively provided with a pivoting portion 33. In the embodiment, the seat cushion has two side edges 34 away from the second fold line 32. The portion 33 is located at a position close to the two side edges 34. The seat pad 3 is disposed on the first support portion 11 of the two side frames 1 and is pivotally disposed on the first support portion by two pivot portions 33. The top edge of 11 With the above structure, when the seat cushion 3 is in a state in which the folded flat plate has not yet been formed, as shown in FIG. 3, it completely covers the first support portion 11 of the side frame 1, and is subjected to the first support portion 11 and the connection. The top support of the piece 21A further strengthens the stability of the seat pad 3.
Further, the first fold line 24 of each of the connecting members 21A, 21B, and 22 and the second fold line 32 of the seat cushion 3 are located on the same plane (ie, the Y-Z plane), and the plane and the side frame 1 The distances are equal; in other words, the positions of the side frames 1 are symmetrical with each other centering on the plane formed by the respective fold lines 24, 32.
With the above structure, the two first combining portions 23 can be folded along the first folding line 24 through the connecting members 21A, 21B, and 22, and the second combining portion 31 can be folded along the second folding line 32 by the cushion plate 3 to make two The side frames 1 are close to each other in the X direction, so that the distance between the side frames 1 is shortened as shown in Fig. 4, and finally the invention changes from the chair type to the folded shape as shown in Fig. 5, which is greatly reduced. The volume it occupies, whereby the more folded invention can be accommodated in a limited storage space.
In the above structure, the first supporting portions 11 of the two side frames 1 are respectively provided with the first through holes 14 corresponding to the positions, and are used for carrying the extraction holes of the chair when the invention is opened to form a chair, which is convenient. In addition, the second through-holes 35 corresponding to the second fold lines 32 of the seat cushion 3 are respectively disposed adjacent to the second fold line 32, and can be used as the take-up holes after the folding of the present invention. It also achieves the purpose of easy handling.
The disclosure of the above embodiments is intended to be illustrative of the invention and is not intended to limit the invention.
In summary, it will be apparent to those skilled in the art that the present invention can achieve the foregoing objectives and is in accordance with the provisions of the Patent Law.
