[Conventional technology]

Conventionally, when closing a door attached to a box such as a safe, the tip of the locking rod may be erroneously projected from the periphery of the back surface of the door. There is a risk of colliding with etc. As a safety device for preventing the collision of the locking device, for example, Japanese Utility Model Publication No. 42-18765.
And the devices represented by No. 58-83575 are known. In these devices, as understood from the contents disclosed in the publication, the actuating piece for restricting the locking operation of the locking rod has a leaf spring in which the tip abutting portion which abuts the upper frame of the case body and the main body. Since it is made integrally with, it is not only difficult to bend and form the leaf spring in this way, but the tip repeatedly collides with the upper frame of the storage case and other protrusions during use. It may be deformed and the elastic restoring force of the operating piece deteriorates.In addition, the locking rod is positioned on one side of the operating piece when viewed from the back side of the door, and a protruding piece for engaging and disengaging with the locking rod is provided. Since it must project from the side edge of the operating piece to the side, it requires a large installation area in the width direction. Further, since this operating piece is formed by integrally bending the spring plate, it is difficult to surface-treat, and when the tip abutting portion of the operating plate is damaged as described above, There is a problem that there is no compatibility such as exchanging only a part.

[Means for solving problems]

The present invention intends to provide a locking safety device such as a safe, which solves these problems in view of the problems of the prior art.
The gist of this is that an upward movement restricting protrusion projecting from a side of a locking rod of a safe or the like; an upward motion restricting step portion engaging with the upward motion restricting protrusion on one side in the width direction. Provided toward the outside of the middle,
A stopper made of an elastic plate piece, the base end of which is detachably fixed to the back of the door, the upper end of which is tilted forward toward the housing, and the through hole is provided on the other side of the upper end width direction; The base end is loosely fitted in the through hole on the other side of the direction, and the tip is fitted and retracted outward from the opening provided in the decorative plate located in front of the stopper, and spring-biased in the protruding direction from the rear of the base end. It consists of an operating member.

[Action]

As described above, the locking safety device such as a safe according to the present invention is
The protruding piece provided on the side of the locking rod engages with one side of the stopper upper movement regulating step portion made of the elastic plate piece provided on the back surface of the door, and the stopper upper end is a member different from the stopper, The front end is fitted and retracted outward from the opening of the decorative plate on the back of the door, the base end is loosely inserted into the through hole on the other side in the width direction of the stopper upper end, and the operation member is spring-biased from the rear end in the protruding direction. Due to the usage, when the door is open, the stopper is located in a state where it is elastically biased forward from the back surface of the door, and the protruding piece provided on the side of the locking rod is provided on the upper movement restricting step portion thereof. Engagement prevents the locking rod from moving upward. Even if the door is closed to the box of the safe in this state, the tip of the locking rod does not protrude from the peripheral edge of the door, so there is no risk of colliding with the frame of the box, and after closing the door, separate from the stopper. The tip of the operating member, which is the member that protrudes outward from the decorative plate opening, collides with the casing of the storage case, inserts it into the decorative plate against the spring force of the base end, and pushes the stopper upper end toward the back of the door. Because it works
The engagement between the protruding piece of the locking rod and the upward movement restricting step portion of the stopper is released to enable upward movement of the locking rod.
Further, when the door is opened, the locking rod is always set in the unlocked state, so that the elastic biasing force of the stopper and the spring biasing force of the base end cause the operating member to move to its original position, that is, the tip of the operating member is removed from the opening of the decorative plate. It returns to the state of protruding to the outside so that the projecting piece and the upward movement regulating step can be engaged with each other.

[Effect of device]

As described above, the locking safety device such as a safe according to the present invention is
Since the stopper and the operating member are separate members, it is possible to use materials according to their respective characteristics.
The engagement between the protrusion and the stopper is set on one side of the stopper and the mounting position of the operating member is set on the other side, so that the engagement between the stopper and the protrusion and the vertical movement of the protrusion during locking / unlocking are performed. The plate can be freely set without being obstructed by the operating member, and the area in the width direction in the set state of the present device can be minimized, and the stopper is only provided with the upward movement restricting step portion. Even if it is manufactured using an elastic plate piece such as a spring, the manufacturing is easy and there is no difficulty in manufacturing such as bending the tip of the stopper into a shape similar to that of the operating member as in the conventional case. In addition, since the operating member is simply sandwiched between the decorative plate and the upper end of the stopper, its installation is extremely simple, and even when the operating member is damaged after installation of this device, it can be easily replaced. Further, the stopper made of the elastic plate piece has the base end removably fixed to the back surface of the door, so that it can be easily replaced when it is damaged. Also, since the base end of the operating member is spring-biased from the rear in the protruding direction, the stopper and the protruding piece can be engaged more reliably, and at the same time, when the elastic restoring force of the stopper decreases. Also ensures that the operating member located at the tip is restored to its original position.
