Description

{Headrest of chair}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a headrest of a chair, and more particularly, to a headrest of a chair that enables a mesh sheet to be easily attached to and detached from a headrest.

Generally, the chair comprises a leg for supporting the seat and the seat, a backrest coupled to the seat and supporting the back of the user, and a headrest mounted on the backrest to support the user's head.

The backrest and headrest of the chair are provided with a cushion for user's convenience. Recently, a chair using a mesh sheet as a cushion has been manufactured.

Mesh sheets are well ventilated in high temperature and high humidity environments and provide great convenience to users. In addition, the mesh sheet can relieve the fatigue by dispersing the weight of the user, and prevents breeding of ticks due to ventilation, thereby having an excellent function in hygiene.

Figure 1 shows a conventional chair in which a leg 200 is coupled to a lower portion of a seat 100 and a back 300 is coupled to the back of the seat 100. A seat The rest 400 is engaged.

As shown in FIG. 2, the headrest 400 is formed with an inner groove 420 having a certain depth on the outer and lower surfaces of a semicircular frame 410 to support the user's head. A coupling shaft 460 protruding from the center of the lower surface of the frame 410 is formed and the coupling shaft 460 is fitted into a coupling hole formed in the upper portion of the backrest 300, And is fixedly mounted on the upper portion of the backrest 300.

The mesh sheet 430 is cut to fit the shape of the frame 410 and the outer edge region of the cut-out mesh sheet 430 can be closed by a finish. A plurality of fixing members 440 may be formed in the region where the finishing material is formed.

In order to attach the mesh sheet 430 to the frame 410, the operator pulls the mesh sheet 430 and fixes the fixing member 440 to the inner groove 420 of the frame, Is fixed to the frame 410.

However, in such a conventional headrest, when the mesh sheet is coupled to the lower surface of the frame, it is difficult to perform the screwing operation by the coupling shaft formed on the lower surface, thereby reducing the efficiency of manufacturing the headrest have.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a headrest of a chair that allows an operator to easily attach the mesh sheet to the frame of the headrest.

The various problems to be solved by the present invention are not limited to the above-mentioned problems, and other problems not mentioned can be clearly understood by those skilled in the art from the following description.

The headrest of a chair according to an embodiment of the present invention is a headrest of a chair coupled to an upper portion of a backrest of a chair to support a head of a user, A frame formed on a central area of a lower surface of the frame and including a coupling shaft coupled to an upper portion of the backrest and a female screw hole formed in a lower surface of both sides of the coupling shaft, A cover having a mesh sheet formed with a fixing member on its outer side, a cover having a through hole for exposing the female screw hole and facing a lower area of the frame on which the coupling shaft is not formed, And a male screw fixing the cover to the lower surface of the frame.

The mesh sheet may further include a finishing material for finishing the outer side, and the fixing member may be formed on the finishing material.

The cover may include a convex line formed in an area in contact with the inner groove and inserted into the inner groove.

The details of other embodiments are included in the detailed description and drawings.

The terminology used herein is for the purpose of illustrating embodiments and is not intended to be limiting of the present invention. In the present specification, the singular form includes plural forms unless otherwise specified in the specification. Like reference numerals designate the same or functionally similar elements throughout the specification. Accordingly, although the same reference numerals or similar reference numerals are not mentioned or described in the drawings, they may be described with reference to other drawings. Further, even if the reference numerals are not shown, they can be described with reference to other drawings.

3 is a bottom exploded view schematically showing a headrest of a chair according to an embodiment of the technical idea of the present invention.

Referring to FIG. 3, a headrest according to an exemplary embodiment of the present invention may have a groove 520 having a certain depth on the outer and lower surfaces of a semicircular frame 510 to support a user's head. have.

A protruding engagement shaft 580 is formed in the central area of the lower surface of the frame 510 and the engagement shaft 580 is formed on the upper part of the backrest 300 in FIG. So that the headrest is fixedly mounted on the upper portion of the backrest 300.

A female screw hole 550 may be formed on both sides of the lower surface of the frame 510 where the coupling shaft 580 is not formed, for example, on the lower surface of the side frames 510 of the coupling shaft 580.

A mesh sheet 530, which is a cushion for supporting the head of a user, can be coupled to the frame 510. Fig.

The mesh sheet 530 may be cut to fit the shape of the frame 510. [ The mesh sheet 530 may be finished with the outer edge region by a finishing material.

A plurality of fixing members 540 may be formed in an edge region of the mesh sheet 530 or in an area where the finishing material is formed.

The fixing member 540 can be inserted into the groove 520 of the frame 510. [

A cover 560 may be coupled to the lower surface of the frame 510. The cover 561 may be formed to face the lower region of the frame 510 except for the region where the coupling shaft 580 is formed.

Hole 561 for exposing the female screw hole 550 in the area of the cover 560 facing the female screw hole 550 on the lower surface of the frame 510 when the cover 560 faces the lower surface of the frame 510 May be formed.

The cover 560 is coupled to the lower surface of the frame 560 by a male screw 570 screwed into the female screw hole 550 through the through hole 561, It is possible to prevent the fixing member 540 from moving.

A convex line that coincides with the groove 520 is formed in the cover 560 that contacts the groove 520 on the lower surface of the frame 560. When the cover 560 is coupled to the lower surface of the frame 560, The tensile force of the mesh sheet 530 may be increased by pressing the inner sheet 540 to be inserted into the inner groove 520.

According to this configuration, in order to manufacture the headrest by coupling the mesh sheet 530 to the frame 510, the operator pulls the mesh sheet 530 and fixes the fixing member 540 outside the mesh sheet 530 to the inner groove 520).

Thereafter, the cover 560 is brought into contact with the lower surface of the frame 510 including the inner groove 520 into which the fixing member 540 is inserted, and the female screw hole 550 exposed through the through hole 561 of the cover 560 The cover 560 is fixedly coupled to the lower surface of the frame 510. As shown in FIG. The fixing member 540 of the mesh sheet 530 is prevented from being moved by fixing the cover 560 to the lower surface of the frame 510 so that the mesh sheet 530 is coupled to the frame 510. Accordingly, the headrest according to the embodiment of the present invention can be completed.

At this time, the worker can easily work without interfering with the coupling shaft 580 in the operation of coupling the cover 560 to the lower surface of the frame 510.

While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, It will be understood. It is therefore to be understood that the above-described embodiments are illustrative and not restrictive in every respect.
