Description

  The present invention relates to a hanger device that is provided on the back of a chair back and for hanging clothes such as a jacket.

  Among office chairs, there are chairs equipped with a hanger device that allows the upper garment (jacket) to be hung on the back of the chair when the jacket is removed during work.

  The hanger part of the hanger device must be provided at such a height that the hem does not contact the floor when the upper garment is hung. However, if the hanger part is provided at such a position, the hanger part will be seated when the upper garment is not hung. This hanger part is obstructive because it protrudes upward from the upper end of the head, which is troublesome.

  Therefore, conventionally, a hanger has been proposed that protrudes above the backrest when used as a hanger and is moved down so as not to get in the way when not in use (see Patent Document 1). ).

In the above-mentioned Patent Document 1, a rectangular tube-shaped fixed seat is provided at an intermediate position in the vertical direction of the back of the chair back, and a column having a hanger at its upper end is inserted into the fixed seat so as to be movable up and down. A large number of holes are arranged in a vertical direction with a certain pitch, and a hanger can be placed at a predetermined height position by inserting a stopper inserted through the back of the fixed seat into one of the holes. It was made.
Utility Model Registration No. 3084421

  In the hanger device described in Patent Document 1, when the height of the hanger is adjusted, the clasp is removed every time, and then the strut is adjusted to a desired height, and then the clasp is inserted again to fix the strut. Therefore, not only is the height adjustment operation cumbersome, but the fixed seat protrudes greatly on the back of the backrest, which impairs the design of the chair and interferes with it. Further, since a stopper as a separate part is required, there is a problem that the stopper is lost or the number of parts increases and the structure becomes large.

  The present invention has been made to solve these problems.

  As means for solving the above-mentioned problems, the present invention is arranged so as to face two mutually parallel ridges, hangers attached to the upper ends of these ridges, and at least the lower part of the opposite side surfaces of the ridges.

A holding member to be held, and the locking tool is mounted in the holding member.

  According to the present invention, a hanger is provided at the upper end of two parallel saddle members, and this saddle member is inserted into and supported by a receiving part provided on the back part of the backrest so as to be slidable in the vertical direction, and is mounted in the receiving part. By engaging the engaging protrusions of the engaging fixtures with the engaging grooves formed corresponding to the opposite side surfaces of the saddle material, the saddle material is retained at the engagement position. Can be switched to a non-use position with one touch, and each time there is no troublesome operation such as replacement of a clasp, it can be used easily.

  In addition, since the receiving part only slides and supports the saddle material, it does not protrude greatly on the back of the backrest, does not impair the design of the chair and is not so thick in appearance. There is no sense of incongruity in the design of the chair.

  According to claim 2, when the hanger is lowered and stored, the saddle material is locked, so that the hanger does not move up and down in a disorderly manner and is kept in a stable and unused state. be able to.

  According to the third aspect, since one bar can be bent into a vertically long U-shape, it is possible to obtain two parallel bars, so that not only the manufacture is easy, but the bent portion at the lower end is upward. Therefore, it is not necessary to provide any special retaining means for the brazing material, and the design can be made clean.

  According to the fourth aspect, since the locking tool for locking the saddle member at a predetermined position can be constituted by one piece, there is an advantage that the structure can be simplified and can be manufactured easily and inexpensively.

  According to the fifth aspect, since the hanger can be attached simply by press-fitting into the upper end of the saddle member, the design of the hanger can be arbitrarily selected, and there are a plurality of types (different colors, etc.) for the chair with the same structure. If a hanger is prepared, it can be provided as a chair with a hanger of a desired design according to the needs, and it is possible to prevent the saddle from slipping upward.

  Further, according to the sixth aspect, the receiving portion for inserting and supporting the saddle member so as to be slidable in the vertical direction can be configured more compactly, and a reliable operation can be achieved.
