Description

The present invention relates to a locking / unlocking confirmation apparatus that can easily check whether a drawer such as a cabinet is locked.

In order to be able to confirm the unlocked / unlocked state of the drawer even from a distance, the lock provided on the front of the drawer is provided with a display board indicating the unlocking / unlocking on the front of the locking rod that reciprocates by the locking / unlocking operation. There is provided a confirmation window provided with one of the display panels so that the lock of the drawer can be easily visually confirmed. (For example, refer to Patent Document 1.)
In the above configuration, the front side of the belt-like locking rod that moves left and right by the key unlocking operation is secured to the front plate of the drawer with the unlocking display plate and the locking display plate attached to the front side by side. Is provided with a confirmation window for exposing either one of the two display panels at a corresponding position of the both display panels.

According to the said structure, the means (welding etc.) for adhering a mounting bracket to a strip | belt-shaped locking rod is needed. In addition, as a device for confirming unlocking / unlocking of drawers, it is necessary to store and manage each member until it is installed on the back of the front plate of the drawer (cylinder lock, strip-shaped lock rod, etc.). Since it is fixed, it is not easy to store and manage the belt-like locking rod (the cylinder lock with the belt-like locking rod) in an orderly manner.
In addition, the display board is attached to the front of the mounting bracket side by side, and the mounting bracket is fixed to the front of the belt-like locking rod that moves to the left and right by the key unlocking operation. Therefore, the cylinder lock cannot be provided on the left and right ends of the front plate of the drawer.
In other words, the cylinder lock cannot be installed in an inconspicuous position in order to improve the design, and it is inevitably provided at the center of the drawer front plate so that there is no sense of incongruity. There was a problem of not being able to bring a feeling.

Japanese Utility Model Publication No. 63-19667

In view of such a problem, the present invention has a simple configuration, and each member can be stored and managed easily. The display plate is positioned above the cylinder lock, and the cylinder lock is attached to the left and right ends of the front plate of the drawer. It is also an object to provide a locking / unlocking confirmation device that can also improve the design.

Therefore, in order to solve the above problems, the present invention is configured as a first means for drawers in furniture such as cabinets, which is composed of a front plate and a back plate, and has a space portion formed inside. A lock body with a cylinder lock and a case containing the cylinder lock inside the front plate, and a lock body connected to the lock body, reciprocating in the left-right direction in conjunction with the unlocking operation of the cylinder lock, one end of the drawer A locking rod that locks and unlocks the drawer by advancing and retreating from the side, and a display body that reciprocates in the left-right direction in accordance with the reciprocating movement of the locking rod in the left-right direction, and displays the locked and unlocked state of the drawer In the locking / unlocking confirmation device composed of a display window provided on the front plate so that the state of locking and unlocking can be confirmed, the display body is detachably attached to the locking rod and is positioned above the lock body. , Locked from the confirmation window, It consists of a display front plate having a display unit that indicates the state of the lock, and a moving continuous plate that is connected to the display front plate and reciprocally moves the display front plate in conjunction with the reciprocating movement of the locking rod. The front plate for a board is provided with the guide part which controls the downward motion of a display body by mounting on the upper surface of a lock main body.

Next, in order to solve the above-mentioned problem, the present invention is configured as the second means. In addition to the first means, the lock body provided with the locking rod is mounted on the back plate, The engaging portion provided on the locking rod has a detachable engaging portion, and the display body is not movable to the left and right with respect to the locking rod while the engaging portion is engaged with the engaged portion. In addition, the display body is held between the locking rod and the front plate of the drawer so as to be movable in the left-right direction in conjunction with the locking rod.

According to the configuration as the first means, since the display body is detachably attached to the locking rod, it is easy to store and manage each member until it is assembled on the back of the front plate of the drawer. Is easy and the total cost can be reduced.
Since the display portion is located above the lock body, the lock body can be provided on the left and right end portions of the front plate, so that the keyhole is not conspicuous and the front plate can be improved in design.
According to the configuration as the second means, in addition to the effect of the configuration as the first means, the display body has an engaging portion that can be freely engaged with and disengaged from the engaged portion provided in the locking rod. Since it is held between the lock rod and the front plate of the drawer so that it can move in the left-right direction in conjunction with the display, it does not require screws or the like to attach the display body, and assembly is easy and the cost can be reduced.
