Abstract

PROBLEM TO BE SOLVED: To provide a board body with a latch mechanism, which simply and strongly houses therein the latch mechanism and a lock without applying any spot welding to a front surface member, and unifies the standard and structure of members other than indispensable minimum kinds of members, to thereby drastically cut production costs. SOLUTION: The board body 1 is formed of steel, and houses therein a mechanism for driving the latch which engages with or disengages from a casing opening by operating a door pull portion 6. The board body is comprised of a front surface member 3, a rear surface member 4, and a rear cover member 5. The front surface member 3 consists of a front surface plate 9 and an edge plate 10 attached to the periphery of the front surface plate 9 in a manner being folded to the rear side of the board body. The rear surface member 4 has a rear surface board fixed to the rear surface of the front surface member except for an installation space 11 along one side edge. The rear cover member 5 is interposed between the rear surface member and the edge plate on the one side edge of the front surface member. Then, the latch mechanism portion 1 and the lock 8 are held by the rear cover member and a member arranged on the rear cover member, without applying welding to the front surface plate of the front surface member.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plate with a latch mechanism, and more particularly to a plate with a latch mechanism used as a door or a front plate for drawing out provided in an opening of a cabinet such as a cabinet.

[0002]

2. Description of the Related Art Conventionally, like a door of a cabinet, a front member and a back member formed by bending a steel plate are combined with each other, and a latch mechanism and a locking device interlocked with a pull portion are built in the inside. Various things are provided.

Here, since the latch mechanism and the lock have high mounting strength, a structure is adopted in which a steel mounting member is mounted by spot welding on the back surface of the surface member. And the appearance is impaired.
In particular, when the coating process is simplified or omitted using a decorative steel plate, spot welding to the surface member must be avoided.

[0004] On the other hand, it is considered to attach all the mechanism parts of the latch mechanism and the locking device to the back surface member, but it is structurally necessary to join the back surface member to the front surface member with the mechanism part attached. Not only is this difficult, but if the bonding strength between the front surface member and the back surface member is not sufficient, there is a problem from the viewpoint of antitheft property. In addition, when there are various dimensions such as a door body, if the specifications and dimensions of the latch mechanism and the locking device must be changed accordingly, the number of steps increases, which eventually increases the cost.

[0005]

SUMMARY OF THE INVENTION In view of the above situation, the present invention is to solve the above problem by simply and firmly incorporating a latch mechanism and a locking device without performing any spot welding on a surface member. It is another object of the present invention to provide a latch-equipped plate body capable of achieving a large reduction in cost by unifying the specifications and structures of members other than the minimum necessary members.

[0006]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention has a built-in mechanism for driving a latch which is engaged with and disengaged from a housing opening of a cabinet body or the like by operating a handle facing a surface. A plate member made of a steel plate, wherein the plate member has a surface member having an edge plate bent to the back side around the surface plate,
A back surface member having a back surface plate fixed to the back surface side of the front surface member while leaving a mounting space along one side edge thereof; and a back surface mounted between the back surface member and the edge plate on one side edge of the front surface member. A latch mechanism comprising a cover member, and holding the latch mechanism and the locking device with the edge plate, the back cover member, and the member provided on the back cover member without applying any welding to the surface plate of the surface member. An attached plate was constructed.

Further, one side edge of the back cover member is engaged with an edge plate portion of the surface member along the mounting space, and the other side edge of the back cover member is screwed to one side edge of the back surface member. It is fixed and stopped.

Further, a notch formed in a part of a surface member corresponding to the mounting space has an opening for mounting a pull cover, and is formed in an inwardly folded piece of both edge plates corresponding to a longitudinal end of the mounting space. A shaft portion of a latch provided at both ends of the shaft is rotatably engaged with the bearing, and an operating member having a pull tab is attached to an intermediate portion of the shaft to be positioned at the opening. It is preferable that bearings made of synthetic resin are fitted into the fitting holes provided at the two locations from the back side, and the shafts at both ends of the operating member are held between both leg pieces of the bearing.

[0009] An insertion hole for the locking device is formed in a part of the surface member corresponding to the mounting space, and an insertion portion of the locking device is inserted into the insertion hole from the back side, and a back plate portion of the back cover is formed. It is also a preferred embodiment that the locking device main body is held by a holding piece protruding from the inner surface of the back cover.
