The present invention relates to a back seat structure of a chair, and more particularly, to a back seat structure of a chair which easily combines the sponge and the skeleton of the back plate and the seat of the chair and makes the finish shape of the finishing material constant.

In general, the chair can be manufactured in various forms according to its use. However, the chair is generally divided into a back and seat plates, and a fixed chair composed of support bars mounted on four sides of the seat to support the chair, and also the bottom of the seat. It can be classified as a movable chair by mounting a rod-shaped rod in the center and a pedestal with rollers at the lower end of the rod.

As shown in FIG. 1, the back plate 10 and the seat plate 20 of the chair have sponges 12 and 22 and sponges 14 and 24 coupled to the skeletons 12 and 22 to provide a substantial cushion. In addition, the sponge (14, 24) is wrapped and consists of a finishing material (16, 26) made of leather, cloth, leather or the like to contact the actual user. In general, the back cover 10 is coupled to the back cover cover 18 to clean the skeleton and the finish.

Conventionally, the skeletons 12 and 22 and the sponges 14 and 24 are bonded with an adhesive such as a bond, and the finishing materials 16 and 26 are Taka working by using a plurality of takapins in the skeletons 12 and 22. It is fixed through.

However, the conventional frameworks 12 and 22 and the sponges 14 and 24 are bonded to each other by an adhesive such as a bond and thus contain harmful elements, and since the skeleton and the sponge are not completely separated, there is a difficulty in disposal and recycling. there was.

In addition, since the finishing materials (16, 26) are fixed using takapin, the fixing work is not easy and there is a problem in that disposal and recycling are more difficult because takapin must be removed during the separation work of the finishing materials (16, 26). In order to solve the problems caused by the use of takapin, as disclosed in Korean Utility Model Registration No. 20-0290128, a structure is proposed in which a core is embedded by sewing on the edge of the finishing material, and the core is pulled and tied to give the finishing material a tension. However, due to the bond bonding of the sponge there is still a problem of disposal and recycling, there is a problem that the finish shape of the finishing material is changed when pulling the core material (pull room).

The present invention is made to solve the above problems, an object of the present invention is to provide a backrest structure of the chair to facilitate the disposal and recycling of the chair and to improve the quality of the product by the constant finish shape of the finishing material.

The back seat structure of the chair according to the present invention is a back seat structure of a chair comprising a skeleton, a sponge coupled to the skeleton to provide a substantial cushion, and a finishing material covering the sponge to be in contact with an actual user. A locking projection is formed at an edge, and a locking groove to which the locking projection is fitted is formed at a rear edge of the sponge.

A core is embedded at the edge of the finish by sewing, and a locking jaw is formed on the outer surface of the skeleton to hold the core, and the core is pulled and tied to fix the finish.

A plurality of engaging holes are formed on the outer surface of the skeleton, and the engaging holes are engaged by engaging a cover covering the edge of the finishing material.

Hereinafter, with reference to the accompanying drawings will be described an embodiment of the present invention; In the present embodiment, only the back of the chair is described as an example.

2 and 3 are a perspective view and an exploded perspective view showing a back plate to which the back seat structure of the chair according to the present invention is applied, and FIGS. 5 to 7 are cross-sectional views of FIG. 4 (rear elevation view), and FIG. Fig. 10 is a partial detailed view of the state in which the core material is removed from Fig. 9. As shown, the skeleton 110 is coupled to the sponge 120 that provides a substantial cushion, and wraps around the skeleton 110 and the sponge 120 and is covered with a finishing material 130 which is in contact with an actual user, and fixed to the skeleton. On the rear of the 110, a cover 140 covering the finish of the finish 130 is fixed.

In the cover 140, a connecting rod 160 connected to a seat plate (not shown) is fixed to the frame 110 by the fastening member 150.

A concave indentation 111 is formed in the lower portion of the outer surface of the skeleton 110 to be closed by coupling the cover 140 and the concave indentation portion 111 is caught by a locking protrusion, which will be described later, of the cover 140. A plurality of engaging holes 112 are formed along the edge of the recess 111 to form a core material (thick thread), which will be described later, coupled to the finishing material 130 at four corners of the recess 111. The latching jaw 113 is formed to be caught. A portion of the concave inlet 111 in contact with the connecting member 160 forms a further recessed groove 111a.

The frame 110 is made of plywood or plastic material. In addition, as illustrated in FIG. 6, an edge of the skeleton 110 is provided with a locking protrusion 114 that is caught by a locking groove of the sponge 120, and a plurality of reinforcing ribs are formed on an inner surface of the skeleton 110. 115 is formed.

The rear edge portion of the sponge 120 is formed with a locking groove 121 to which the locking projection 114 is fitted.

The finishing material 130 is made of a material such as cloth, leather or leather, only the recessed portion 111 of the skeleton 110 is open, the rest is in the form of a closed cover. In the open part of the finishing material 130, a core material 131 made of thick thread along the edge thereof is embedded by sewing to pull and tighten the end 131a of the core material 131. The core material 131 is caught by the locking jaw 113 and is appropriately pulled. The locking jaw 113 is formed at an inner surface thereof by a hole 111b formed at an edge of the recess 111.

On the inner side surface of the cover 140, a plurality of locking projections 141 to be fitted into the locking hole 112 is formed (see Fig. 7).

The back plate to which the present invention configured as described above is applied, the locking protrusion 114 of the skeleton 110 is fitted into the locking groove 121 of the sponge 120 to be simply coupled and separated, and the finishing material 130 to the skeleton 110. ) And the core 120 is pulled and tightened by tightening the core material 131 from the indentation portion 111 of the skeleton 110 to cover the combination of the sponge 120, so that the finishing material 130 can be easily combined and separated. Do. Therefore, the backplate can be easily disposed of and recycled.

And, when fixing the finishing material 130, the core material (131: thread) is caught on the locking jaw 113 and pulled appropriately under the guidance, so that the finish shape of the finishing material can be made constant, thereby increasing the quality of the product. do.

On the other hand, the coupling structure of the skeleton and sponge to the seat plate and the fixing structure of the finish is the same as the coupling structure of the skeleton and sponge to the back plate and the fixing structure of the finish. That is, the technique of the present application applied to the back of the chair can be similarly applied to the seat of the chair.

According to the back seat structure of the chair according to the present invention, there is an effect of facilitating the disposal and recycling of the chair and to make the finish shape of the finishing material constant to increase the quality of the product.
