A conventional method for comfortably supporting the head and neck of a user is disclosed in Korean Utility Model Registration No. 20-0326836 (design name: neck-headrest of a car chair), Korean Patent No. 10-1656661 (Headrest for a chair which is variable in its neck support).
The technical structure described above is a background technique for assisting the understanding of the present invention, and does not mean the prior art widely known in the technical field to which the present invention belongs.
Conventional chair headrests are adjustable in height or tilting according to the body shape of the seated person. The position variable device of the headrest is exposed to the outside, resulting in a deterioration of aesthetic sense, and a safety accident such as a part of the body is caused.
In addition, the conventional headrest for a chair has a disadvantage in that it is difficult to separate and install the position variable device and maintenance because of inconvenience.
Therefore, there is a need to improve this.
SUMMARY OF THE INVENTION It is an object of the present invention to provide a chair which can easily couple and detach a headrest to and from a back, .
It is another object of the present invention to provide a chair for enhancing a sense of beauty and merchandise by preventing the joint between the headrest and the backrest from being exposed to the maximum extent in the backrest.
A chair according to the present invention comprises: a mounting bracket provided on a headrest; One or more rails provided on the back; And a joint for fitting the mounting bracket and adjusting the height of the headrest by permitting linear reciprocating movement along the rail portion.
The mounting bracket includes: a body detachably coupled to the headrest; And a mounting rib extending from the body and detachably coupled to the joint.
The joint comprising: a body; An assembling hole formed in the body for axially inserting the mounting rib; A roller member rotatably provided to the main body so that the main body is movable while being guided by the rail portion; And an elastic piece extending from an edge of the assembly hole part to the rail part side and elastically deformable to press the mounting rib inserted into the assembly hole part at least at both sides.
The mounting rib may be recessed to receive the elastic piece. The elastic piece may be received in the receiving groove and protrude from the receiving protrusion to maintain the coupled state of the mounting rib.
Wherein the rail portion includes: a frame detachably coupled to the backrest, the frame having the joint on the inside and passing through the communication hole for guiding movement; And a concavo-convex portion formed on an upper edge of the communication hole portion to guide the rotation of the roller member in the rolling direction and to set the multi-stage position of the headrest and prevent the body from being released to the lower side of the frame do.
The body can be prevented from being separated from the frame naturally by the escape prevention portion.
Wherein the separation preventing portion comprises: a supporting protrusion formed on the frame corresponding to a lower edge of the communication hole portion; And a supporting protrusion extending from the elastic piece and contacting the supporting jaw, for guiding the roller member to be forcedly moved along the concave-convex part and preventing the main body from being separated from the upper side of the frame.
The frame may be formed with chamfered portions at one side edge with respect to the central axis direction of the communication hole portion for inserting the receiving protrusions protruding outward so as to correspond to the supporting protrusions projecting inward from the respective at least one pair of the elastic pieces .
The body may be provided with spacers to guide reciprocating movement in contact with the inner surface of the frame.
As described above, the chair according to the present invention can easily couple and separate the headrest to and from the back, unlike the prior art, and can provide convenience in maintenance through easy separation and coupling.
In addition, since the joint between the headrest and the backrest is not exposed to the maximum extent in the backrest, the present invention can increase the esthetics and the merchantability.
