Description

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

The hanger mounting structure in a chair is described in Patent Documents 1 and 2, for example.
JP-A-9-206169 However, as shown in these patent documents, the mounting structure of the hanger in the conventional chair generally includes a support rod that supports the hanger body in the vertical direction, and the horizontal direction of the support rod. Using a mounting member having a width larger than the width of the backrest, it is fixed to the back surface of the backrest. The mounting member has been formed with a focus on the functional aspect of fixing the hanger so as not to wobble. For this reason, the mounting member is conspicuous on the back surface of the backrest and protrudes from the backrest, so that the appearance is not good and there is a problem in appearance. In addition, in the case of a small chair, the ratio of the mounting member is increased, and the advantage of being small is lost, so that there is a problem that it is difficult to attach the hanger.

In view of the above problems, the present invention reduces the proportion of the mounting member on the appearance, incorporates the mounting member as a part of the design element, and exhibits a smart and excellent design as a whole, and a hanger. It is an object of the present invention to provide a hanger mounting structure for a chair that can be held 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 in the up-and-down direction. The hanger is attached to the back side of the backrest by providing the stepped portion and disposing the mounting member by fitting the left and right ends thereof to the both concave stepped portion and screwing it to the backrest.

  (2) In the above item (1), the two concave steps provided on the opposing surfaces of the pair of left and right support rods that open in the opposite direction and the rear are provided in the vertical direction so as to be parallel to each other. The support rod provided with the hanger body is movable relative to the mounting member screwed to the backrest in the vertical direction.

  (3) In the above item (1) or (2), the opposing surfaces of the pair of left and right support rods are provided with protruding ridges extending backward in parallel with each other in the vertical direction, A fitting groove is provided in the ridge so as to be slidable in the vertical direction.

  (4) In the above item (3), the ridges on the facing surfaces of the pair of left and right support rods are provided on the left and right inner edges of the recessed stepped portion where the facing direction and the rear open.

  (5) In any one of the above items (1) to (4), a plurality of small protrusions protruding rearward are provided on at least one of the opposing surfaces of the pair of left and right support rods so as to be spaced apart from each other. An engagement hole for engaging the small protrusion on the front surface and a support rod provided with a hanger body on the upper end can be held at a plurality of vertical positions where the small protrusion engages with the engagement hole. To.

  (6) In any one of the above items (1) to (5), a front surface of the pair of left and right support rods is provided with a locking protrusion that protrudes in the vertical direction and protrudes forward, and the back surface of the backrest A vertical locking groove that can be locked by the locking ridge is provided.

  (7) In any one of the above items (1) to (6), the mounting member and the support rod provided with a threaded screw through hole on the backrest and the hanger body on the upper end are arranged on the rear side of the backrest. With the mounting member held in place, hold the backrest with the mounting member and the screw seat piece, and screw the screw to the screw seat piece from the rear of the mounting member, so that the hanger is placed behind the backrest. A cover member that covers the exposed head of the screw to be screwed is attached to the rear surface of the attachment member.

According to the present invention, the following effects can be obtained.
According to the first aspect of the present invention, the recesses are provided on the mutually opposing surfaces of the pair of left and right support rods, and the mounting member is disposed by fitting the left and right ends thereof to the both recesses. Therefore, the mounting member does not protrude outside the pair of left and right support rods, and the appearance of the mounting member is small in appearance, and the mounting member is supported between the pair of left and right support rods. As a part of the design element, it is integrated as a part through the recessed step portion of the, and the smart and excellent design is exhibited as a whole.
Moreover, since the support rod is firmly held by the mounting member via the recessed step portion, the hanger does not wobble.
Moreover, since the attachment member is formed as a small member that does not protrude outside the pair of left and right support rods, the hanger attachment structure can be applied practically to a small chair. Yes.

  According to the second aspect of the present invention, since the both recessed step portions provided on the pair of left and right support rods are parallel to each other, the support rod provided with the hanger body at the upper end is screwed to the backrest. Even if it is moved relative to the mounting member in the vertical direction, the fitting state between the left and right ends of the mounting member and the recessed stepped portion is always stable, preventing the hanger from wobbling. It can be held stably.

  According to invention of Claim 3, a hanger can be hold | maintained more stably stably by fitting with the protruding item | line of a support rod, and the fitting groove of an attachment member.

  According to the invention of claim 4, since the ridges in the support rod are provided in the left and right inner edges of the recessed stepped portion, the fitting groove that fits the ridges on the front surface of the attachment member is attached. It becomes possible to provide the inner side to a considerable extent from the left and right ends of the member, and damage to the fitting groove due to breakage of the left and right ends of the mounting member can be prevented.

  According to the fifth aspect of the present invention, the hanger body can be brought to a desired height by selecting one from a plurality of positions where the small protrusions of the support rod and the engagement holes of the mounting member are engaged. it can. For example, when the hanger is used, the hanger body can be made high so that the lower end of the clothes does not come into contact with the floor surface and become dirty, and when the hanger is not used, the hanger body can be lowered to make it compact.

  According to the sixth aspect of the present invention, when the support rod provided with the hanger body at the upper end is attached to the rear side of the backrest with the attachment member, the support rod is positioned in the left-right direction on the rear surface of the backrest. This locking protrusion can be easily performed by locking the locking protrusion in the backrest locking groove.

  According to the invention of claim 7, the hanger can be firmly attached to the back side of the backrest, and the exposed head of the screw to be screwed is covered with the cover member. Moreover, coupled with the fact that the mounting member is disposed between the pair of left and right support rods, the mounting member is integrated as a part of the design element so that even the mounting member cannot be easily recognized. A smart and well-designed design is formed.
