Description

  The present invention relates to a mounting structure for a hanger in a chair.

The hanger mounting structure in the chair is described in Patent Documents 1 and 2, for example.
As shown in these patent documents, the hanger mounting structure in the conventional chair generally has a support rod that faces the vertical direction that supports the hanger body, and has a width that is larger than the width in the left-right direction of the support rod. The fixing member is fixed to the back surface of the backrest using a member, and the mounting member is formed mainly focusing on the functional aspect of fixing the hanger so as not to wobble. For this reason, there is a problem in that the ratio of the mounting member to the exterior of the chair increases on the back of the backrest, and the mounting member is conspicuous and a good design cannot be obtained.
Further, in the case of a small chair, the ratio of the mounting member is excessive, and the advantage of being small is lost, so that there is a problem that it is difficult to mount the hanger.
JP-A-9-206169 Japanese Utility Model Publication No. 5-7179

In view of the above problems, the present invention reduces the proportion of the mounting member, incorporates the mounting member as a part of the design element, exhibits an excellent smart design as a whole, has excellent assemblability, and It is an object of the present invention to provide a mounting structure for a hanger in a chair, which can hold the hanger highly stably so as not to wobble.
Another object of the present invention is to provide a hanger mounting structure that can be applied practically to a small chair.

The above-described problems are solved by the invention having the following configuration, as shown in each of the claims.
(1) The hanger is composed of a hanger body and a pair of left and right support rods that support the hanger body, and the front and rear sides of the left and right support rods are open in the vertical direction with the opposite direction and the front opening. The front recessed steps are provided in parallel to each other, and the rear recessed steps in the vertical direction in which the facing direction and the rear are opened are arranged in parallel to each other on the rear portions of the facing surfaces of the left and right support rods. The left and right ends are fitted to the left and right front recessed steps, and the rear mounting members are fitted to the left and right rear recessed steps. And, by attaching both mounting members to the hanger mounting part in the backrest and sandwiching the both support rods with both mounting members, the hanger was mounted on the rear side of the backrest so that the vertical position can be adjusted. A hanger mounting structure for a chair.
