Detailed Implementation
[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0039] Example 1
[0040] like Figure 1 As shown, this embodiment provides a compact folding chair that is easy to fold, including a backrest 1 and a chair frame 2.
[0041] In this embodiment, the backrest 1 includes a backrest body 101, which is divided into a seat area and a backrest area. A backrest support rod 102 is installed on the outside of the backrest area of the backrest body 101.
[0042] like Figures 3-4 As shown, the backrest support rod 102 has a foldable structure. The backrest support rod 102 can be configured as a two-section folding support rod, which can automatically lock into the straightened state after being straightened.
[0043] In this embodiment, the chair frame 2 includes two groove-shaped armrests 201. A folding structure for the chair frame that can be folded and unfolded is installed between the side bars of the two armrests 201. The middle part of the folding structure of the chair frame has an empty space that facilitates the compact folding of the fabric in the seat area.
[0044] In this embodiment, the backrest body 101 is connected to ribbons 103 on both sides of the seat surface area, and the ribbons 103 are directly or indirectly connected to the armrest bar in the middle of the armrest component 201.
[0045] In this embodiment, a backrest connecting strip 104 is installed between the rear end of the ribbon 103 and the side of the backrest area adjacent to the backrest body 101, and a seat connecting strip 105 is installed between the rear end of the ribbon 103 and the rear end of the seat surface area adjacent to the backrest body.
[0046] In this embodiment, the backrest body 101 is equipped with seat support components on both sides of the seat surface area to prevent the seat surface fabric from gathering.
[0047] The specific application of this embodiment is as follows: The folding chair has a reasonable structural design, including a backrest 1 and a chair frame 2. The backrest body 101 of the backrest 1 is divided into a seat area and a backrest area. A backrest support rod 102 is installed on the outside of the backrest area of the backrest body 101. By setting the backrest support rod 102 as a foldable structure, the product has a smaller volume after being folded.
[0048] Example 2
[0049] This embodiment is an improvement upon Embodiment 1, such as... Figure 2 As shown, the backrest body 101 is equipped with an anti-torsion component 106 that is connected to the top end of the backrest support rod 102 on the outer side of the backrest area.
[0050] The anti-torsion component 106 is designed to prevent the backrest support rod 102 from rotating in the fabric, which would hinder quick folding. At the same time, when two or more backrest support rods 102 are used, they can be combined with the anti-torsion component 106 to achieve synchronous folding.
[0051] Example 3
[0052] This embodiment is an improvement upon Embodiment 1, such as... Figures 5-7 As shown, the chair frame folding structure includes two folding units. Each folding unit includes a first connecting rod 202, a second connecting rod 203, and a limiting connector 204. The first connecting rod 202 is hinged to the side rod of one armrest component 201 via a first pin, and the second connecting rod 203 is hinged to the side rod of another armrest component 201 via a second pin. The first connecting rod 202 and the second connecting rod 203 are hinged together via the limiting connector 204 and a third pin. The second connecting rods 203 on the same side of the two folding units are hinged together via a fourth pin.
[0053] In this embodiment, the first connecting rod 202 and the second connecting rod 203 are each either straight rods or U-shaped rods. When a U-shaped rod is used, the middle connecting rod of the U-shaped rod is located in the outer region away from the backrest, thereby creating a space in the middle of the chair frame folding structure that facilitates the compact folding of the seat fabric.
[0054] In this embodiment, the limiting connector 204 includes a connector housing 204a. The connector housing 204a is provided with a plug groove 204b for installing the second connecting rod 203 and a limiting snap groove 204c for installing the first connecting rod 202. The limiting snap groove 204c is symmetrically provided with pin positioning grooves 204d that cooperate with the third pin on both sides.
[0055] By designing the middle of the chair frame folding structure as an empty space, the fabric of the backrest 1 located in the seat area has enough room to fold, allowing for compact folding.
[0056] Example 4
[0057] This embodiment improves upon Embodiment 1. An armrest cover 205 is installed on the outer side of the middle armrest bar of the armrest component 201. The armrest cover 205 can be attached to the outer side of the armrest bar using Velcro or similar methods, improving the comfort and overall aesthetics of the armrest support. The armrest cover 205 can also be equipped with a handle 206 for easy carrying after folding the product. Figure 9 As shown.
[0058] Example 5
[0059] This embodiment is an improvement on the first embodiment, and also includes a functional table 3. The functional table 3 is installed on the armrest 201 and the tilt angle of the functional table 3 can be adjusted.
[0060] By designing cup holders and other storage slots on the functional tabletop 3, the placement needs of various items can be met.
[0061] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to specific implementation methods. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
