DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a member mounting structure suitably used for mounting one member to another member.

[0002]

2. Description of the Related Art Conventionally, when attaching one member to another, these members are generally welded or screwed together. For example, conventionally, a suspension rail has been used to support the left and right sides of the drawer slidably with respect to the furniture main body. However, when the drawer is slid forward, the suspension rail is exposed to the outside. In addition, there is a problem that the appearance is poor and that the dust enters the rails to make the ball slippery, and that there is a high risk of breakage due to easy application of external force. In order to solve such problems, the left and right side walls of the drawer body
In some cases, a plate-shaped rail cover for concealing the suspension rail is attached. In this case, as described above, the upper end of the rail cover is welded to the upper end of the left or right side wall of the drawer or fastened with a screw. Is generally used.

[0003]

However, in the case of welding, once the rail cover is once attached, it is difficult to remove the rail cover, and the welding marks remain and the appearance is poor. Processing work such as painting is required. On the other hand, in the case of screwing, parts such as screws are required, and the number of parts is increased. In addition, tools and the like are required at the time of mounting, and the work is complicated. In addition, there is also a problem that the screw holes are exposed after removal, and the appearance is poor.

In some cases, one member is attached to the other member via a resin attachment member. In a conventional mounting member, a concave groove is continuously provided along the longitudinal direction, and the wall of one member and the wall of the other member are simultaneously engaged with the concave groove. However, in this case, since the opening width of the concave groove is set to be constant from the opening end side to the opening end side, if the opening width of the concave groove is set so that the engagement between the concave groove and the wall portion is tight. In addition, it is difficult to insert the wall into the opening end, and the mounting operation cannot be performed smoothly. On the other hand, to facilitate insertion,
If the opening width is set to be large, there is a problem in that the engagement between the concave groove and the wall portion is not performed tightly, and rattling occurs, and a stable mounting state cannot be obtained. That is, the conventional mounting structure using the mounting member does not achieve both the smooth mounting workability and the stable mounting state.

[0005] Such a problem is not limited to the case where the rail cover is attached to the drawer, but generally occurs when one member is attached to the other member.

[0006]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, a member mounting structure according to the present invention uses a mounting member to attach a screw or a tool to one member when the other member is mounted on the other member. In addition to eliminating the need for smooth mounting, it is intended to achieve both smooth mounting workability and a stable mounting state.

Furthermore, since the mounting operation of this mounting member is completed by simultaneously engaging the two wall portions with the concave grooves, the working labor is reduced as compared with a case where a plurality of locations are fixed or welded with screws using a tool. It can be reduced significantly.

In a preferred embodiment, it is desirable that one of the opposing surfaces forming the groove extends to the opening end side of the groove more than the other. In order to obtain a more stable attachment state, it is desirable that a part of the wide portion abuts at least one of the wall portion of one member and the wall portion of the other member at a predetermined attachment position. As a preferred embodiment, the groove prevents the interference between the wall of one member and the wall of the other member and the inner periphery of the groove between the wide portion and the narrow portion during rotation. One that has a runaway relief.

[0010] As a specific embodiment of the mounting member,
The attachment member may be a rigid one. Before attaching the other member to the one member, the other member can be temporarily held temporarily by the one member, and the supporting force for the other member is basically carried by a portion other than the attaching member,
In order to stabilize the mounting state, it is desirable that one of the members has a supporting portion for supporting the other member at the mounting position.

In a preferred embodiment, one of the members is a drawer, and the other member is a rail cover for concealing a rail for slidably supporting the drawer with respect to the furniture body from the outside. Can be mentioned.
Further, as a preferred embodiment in this case, the drawer is accompanied by a hanging holder suspended in the storage space, and the attaching member has a hooking portion that can hook both ends of the hanging holder. It is desirable to have it continuously along the longitudinal direction.
