Description

Folding chair {FOLDABLE CHAIR}

The present invention relates to a folding chair, and more particularly, to a folding chair having a simple structure of a seat plate and a backrest structure to simplify the assembly or work process to reduce the manufacturing cost and to greatly increase the ease of use. .

Generally, a chair is a tool for a person to sit on, and includes a leg supporting a floor, a seat on which a person is seated, and a backrest on which a user's back can be leaned. Folding chairs are widely used.

The folding chair has a structure in which the front frame and the rear frame that can support the backrest and the seat plate are pivotable to each other.

On the other hand, the conventional folding chair requires a large number of components in order to provide cushioning properties to the backrest and the seat plate side, whereby the assembly process and workability has a disadvantage that is very degraded.

The present invention has been made in view of the above point, it is an object to provide a folding chair that can reduce the manufacturing cost by simplifying the assembly or work process.

In addition, an object of the present invention is to provide a folding chair that greatly improved the ease of use.

As described above, the present invention provides a folding chair in which a front frame and a rear frame supporting the backrest and the seat plate are rotatably installed.

The seat plate includes an upper layer and a lower layer provided below the upper layer, a hollow portion is formed between the upper layer and the lower layer, and one or more recessed grooves are formed on a bottom of the lower layer.

The upper plate and the lower layer are integrally formed by brow-molding the connecting synthetic resin material, and the support plate is fixedly installed at both left and right ends of the seat plate, and at least one cross member is crossed between the pair of support frames. Is installed.

The support frame is coupled to the lower left and right ends of the seat plate by fasteners, the fastener is fastened to the side of the coupling portion formed integrally with the hollow portion of the seat plate.

The front frame and the rear frame are rotatably installed by a pair of left and right link links, a hook portion is formed on one side of the pair of link links and a groove portion is formed on the side of the other link link.

A fixing bracket is fixedly installed on the rear surface of the backrest, and a fixing ring is installed on the fixing bracket, and the locking ring includes a support part supported on the fixing bracket and a hook part rotatably installed on the support part.

The present invention as described above has the effect of reducing the manufacturing cost by simplifying the assembly or work process by applying a simple structure of the seat plate and the backrest structure.

In addition, the present invention has the advantage of greatly improving its ease of use by connecting the adjacent folding chairs in the left and right directions when using a plurality of folding chairs.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 to 10 show a folding chair according to an embodiment of the present invention.

As shown, the folding chair of the present invention includes a seat plate 10, a backrest 20, a front frame 30, a rear frame 40 and the like.

As shown in FIGS. 2 to 4, the seat plate 10 includes an upper layer 10a having a partially curved upper surface and a lower layer 10b provided below the upper layer 10a, and the upper layer 10a. And a hollow portion 10c is formed between the lower layer (10b), the lower layer (10b) is a portion of which protrudes toward the upper layer (10a) is formed at least one recessed groove 11 in the bottom of the lower layer (10b), The recessed groove 11 may reinforce the supporting rigidity of the lower layer 10b.

The seat plate 10 is formed by connecting the synthetic resin material is brow molded, the upper layer (10a) and the lower layer (10b) is integrally formed, and the support frame 12 of the metal material is fixed to each of the left and right ends of the seat plate (10) At least one cross member 13 is installed across the pair of support frames 12, and the cross member 13 is made of metal.

As described above, the seat plate 10 of the present invention may be easily assembled and the like as the upper layer 10a and the lower layer 10b are formed as an integral one piece by brow molding, thereby greatly reducing the overall manufacturing cost.

In addition, the seat plate 10 of the present invention is reinforced with the rigidity or strength of the seat plate 10 by the recessed groove 11, the cross member 13 and the support frame 12 of the lower layer (10b), and made of a metallic material The support frame 12 is characterized in that the front frame 30 and the rear frame 40 is rotatably installed so that the support structure of the entire folding chair is more robust.

The support frame 12 is coupled to the lower left and right ends of the seat plate 10 by fasteners 12a, and the fastener 12a is integrally formed in the hollow portion 10c of the seat plate 10 ( 15) By being fastened to the side can not only strengthen the coupling structure, but also facilitate the assembly thereof.

A pair of front frame 30 is disposed on both left and right sides of the seat plate 10, each front frame 30 is hinged rotatably through a hinge pin 31 on the support frame 12 side of the seat plate 10 Is coupled, the backrest 20 is coupled to the upper end of the front frame (30).

The backrest 20 is formed to be curvature so as to correspond to the back of the user, as shown in Figure 5, the reinforcement 25 is inserted into the back side of the backrest 20.

A pair of rear frames 40 are disposed on both left and right sides of the seat plate 10, and each rear frame 40 is rotated through a pair of left and right connecting links 51 on the rear side of each front frame 30, respectively. Possibly connected.

One end 52 of the connection link 51 is hinged rotatably coupled to the front frame 30 side, the other end 53 of the connection link 51 is hinged rotatably to the rear frame 40 side. do.

Meanwhile, as shown in FIG. 7, a hook portion 51a is formed by a lancing or the like on the side of one pair of link links 51, and the other side of the pair of link links 51 is illustrated in FIG. 8. As shown in the drawing, the groove 51b may be formed by lancing or the like. With this configuration, as shown in FIGS. 9 and 10, the folding chairs adjacent to each other are coupled to each other by the hook portion 51a and the groove 51b of the connecting links 51 adjacent to each other. It is fixedly connected to each other in the left and right directions so that the arrangement in the left and right directions can be stably maintained. Accordingly, the folding chair of the present invention has an effect of greatly improving its ease of use.

In addition, each rear frame 40 is hinged to the support frame 12 side of the seat plate 10 through a hinge bracket 41, one side end 42 of the hinge bracket 41 is the support frame 12 side The hinge is coupled to, the other end 43 of the hinge bracket 41 is hinged to the rear frame 40 side.

In addition, a fixed bracket 26 is fixedly installed on the back of the backrest 20 as shown in FIG. 6, and a locking ring 27 for hanging a bag or a handbag is installed on the fixed bracket 26. The hook 27 is inserted into and supported by the insertion hole 26a of the fixing bracket 26, and the hook portion 27b rotatably installed through the hinge pin 27c in the support portion 27a. And a spherical stopper 27d is provided at the upper end of the support part 27a, and the support part 27a is supported in the insertion hole 26a of the fixing bracket 26 by the spherical stopper 27d. do. Thereby, as the ring part 27b rotates with respect to the support part 27a, regardless of the rotation angle of the backrest 20, the ring part 27b can hold | maintain the vertical state constant by self weight.
