Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a door lock device mounting structure, and more particularly, to a door lock device mounting structure in a door used for, for example, a partition panel.
[0002]
[Prior art]
For partition panels, etc., a plate-shaped paper honeycomb is used as a core, and the honeycomb core and a channel-shaped frame material are sandwiched by front and back panels made of thin steel plates, etc., and a decorative member is used as a frame material. Conventionally, doors that are assembled and fixed with tapping screws or the like have been used. In view of the fact that this type of door is used for a partition panel or the like, such a configuration is considered in view of the fact that the weight cannot be increased so much in terms of stability and the like.
[0003]
On the other hand, when such a door is provided with a door knob, a latch claw, a locking mechanism, etc., a door lock device in which these are integrally attached to the casing is attached to the anti-hanging side of the door body. Yes. Specifically, the door lock device includes a casing incorporating a latch claw and a locking mechanism, a knob support member fixed to the casing so as to sandwich the door body in the thickness direction from the outside, and the knob support member. And a door knob attached to the casing.
[0004]
In order to attach the door lock device to the door body, an opening for allowing the device body to be inserted is provided in the frame member arranged on the anti-hanging base side, and a pair of device mounting bases are attached to the opening portion. The upper and lower ends are welded to each other, and the mounting flange plate provided in the apparatus main body is screwed to these pedestals. Also, a pair of reinforcing members that are separate from these pedestals are welded to the frame material so as to extend from the vicinity of the upper and lower ends of the opening toward the suspension base, and sandwich the door lock device to which these respective reinforcing members are attached. It is arranged at the opposite position. These reinforcing members are for preventing the panel from being dented in the thickness direction due to the tightening operation when the knob supporting member is assembled.
[0005]
[Problems to be solved by the invention]
However, with such a structure, the pair of pedestals and the pair of reinforcing members must be welded to the frame member, which is troublesome in terms of construction and increases manufacturing costs. Furthermore, when considering that the panel is recessed in the thickness direction due to the tightening operation of the knob support member, the upper and lower reinforcing members and the frame material are mainly responsible for preventing this, for example, improving its function. Accordingly, when a thick frame material is used, the door as a whole is greatly increased in weight, which is not suitable for the purpose of reducing the weight.
[0006]
[Means for Solving the Problems]
Therefore, in order to solve such a problem at a time, the present invention provides a support member by continuously integrating the pair of pedestals and integrally providing a pair of reinforcing materials at both ends of the support member. The pedestal and the reinforcing material are combined into one unit, and the support member is fixed so as to overlap the frame material.
[0007]
DETAILED DESCRIPTION OF THE INVENTION
That is, the door lock device mounting structure according to the present invention is for attaching a door lock device in which a door knob or a latch claw or the like is mounted on a casing to a door body having a frame member arranged on the anti-hanging side. A mounting structure comprising: a supporting member fixed so as to overlap with the frame member; and a pair of reinforcing members each integrally extending from both ends of the supporting member toward the suspension side And a door lock device is attached to the support member constituting the attachment structure.
[0008]
If it is such, since the reinforcing material and the supporting member (pedestal) that have conventionally been separately fixed to the frame material are made into one unit as an attachment structure, the attachment to the frame material can be performed in one step. As a result, it can greatly contribute to the simplification of the process. Furthermore, since the predetermined part of the frame material corresponding to the attachment part of the door lock device is doubled with a support member provided over the entire part of the frame member, the panel member can be prevented from being dented by tightening the knob support member. This can be realized without increasing the thickness of the material, that is, without increasing the weight. Furthermore, such a double structure makes it possible to improve the attachment strength of the door lock device to the door body.
[0009]
In order to obtain various effects such as manufacturing simplification, the mounting structure was formed by bending a single steel plate so as to extend the reinforcing members from both ends of the supporting member so as to form a substantially U shape. It is desirable to be a thing.
[0010]
As a specific embodiment for firmly fixing the frame member and the support member and improving the structural strength at the duplexed portion, the frame member is formed by bending the width plate and both side edges of the width plate.
