BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a key storage device for a cylinder lock device, and more particularly to a key storage device suitable for storing a key for a lock device provided at an entrance door of an elevator machine room.

[0002]

2. Description of the Related Art Conventionally, for example, Japanese Utility Model Laid-Open Publication No.
As described in Japanese Unexamined Patent Publication (Kokai) No. Hei. 2-147594, a storage box for storing a key of a lock device provided at an entrance door of an elevator machine room is provided on an operation panel in a car or an operation panel of a hall. An attachment has been proposed.

[0003]

However, recent buildings tend to be large and high-rise, and a plurality of elevators are generally installed in the building. However, in a conventional key storage device, it is sufficient for a building having a plurality of elevators to have only one operation panel in a car or a hall provided with a key storage box. For this reason, the other units may be conventional ones, and only the operation panel in one car or the landing will have special specifications. For this reason, an extra burden is imposed on both the manufacturer and the user, and since only one operation panel has a different shape, it is not preferable in terms of design. In addition, in order to attach a key storage device to an existing elevator, it is not easy to change an operation panel in a car or an operation panel of a hall to one having the key storage device because special processing is required.

The present invention has been made in view of the above-described problems, and has as its object to provide a key storage device that does not require special equipment and that can be easily attached to a new or existing key. It is in.

[0005]

According to the present invention, there is provided a key storage device for a cylinder lock device provided on a door knob having a large-diameter grip portion and a small-diameter constriction. And a box that has a lid that is suspended from each end of the chain and locks the end when closed, and that stores the key. Configuration.

[0006]

According to the present invention, the key of the cylinder lock device is stored in the storage device, so that the chain is wrapped around the constricted portion of the door knob, and a box is attached to each end of the chain. The body is suspended and the key is stored in the box. Next, the lid of the box is closed to lock the end,
The chained body is prevented from falling out of the constricted portion by using the grip portion of the door knob as a stopper.
As described above, since the key storage device can be arbitrarily installed on the doorknob, no special device is required, and the key storage device can be easily installed irrespective of whether it is new or existing.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a key storage device according to the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing an embodiment of a key storage device of the present invention, FIG. 2 is an exploded perspective view of a chain and a box of the storage device of FIG. 1, and FIG. FIG. 4 is a perspective view showing an open state, and FIG. 4 is a perspective view showing a state in which a lid of the box of FIG. 1 is closed.

The entrance door 1 of the machine room of the elevator is shown in FIG.
As shown in the figure, a large-diameter grip portion 2a and a small-diameter constricted portion 2b
And a cylinder lock device 3 embedded in the door knob 2.

The key storage device of the cylinder lock device 3 according to the present embodiment is hung on a chain, for example, a wire 4 wound around the constricted portion 2a, and on each end of the wire 4. And a lid 5 for locking said end portion when closed.
And a lock device 7 which can be locked and unlocked with a key provided in a control room (not shown), for example. Further, as shown in FIGS. 2 and 3, the end of the wire 4 is
a, 4b are provided, and the engaging portions 4a, 4b are inserted into slits 6a, 6b formed in the box body 6. Further, the engaging portion 4b has a plurality of engaging positions so as to correspond to various diameters of the constricted portion.

In this embodiment, the cylinder lock device 3
When a key (not shown) is stored in a storage device, a maintenance worker wraps a wire 4 around a constricted portion 2b of a door knob 2 of an entrance door 1 of a machine room of an elevator.
The box 6 is suspended by inserting a and b into the slits 6a and 6b, and the key of the cylinder lock device 3 is stored in the box 6. Next, the lid 5 of the box 6 is closed to lock the engaging portions 4a and 4b, and the wire 4 is prevented from coming out of the constricted portion 2b by using the grip portion 2a as a stopper. Thereafter, another lock device 7 is locked using the key provided in the management room described above.

In the embodiment configured as described above, the key storage device can be arbitrarily installed on the door knob 2.
There is no need for special equipment, and it can be easily installed regardless of whether it is new or existing.

[0012]

[Effect of the Invention] Since the present invention is configured as described above, it is not necessary to use a special device, for example, an operation panel of a special specification, for storing a key for an entrance door of a machine room. It is possible to prevent the user from imposing an extra burden, and also to prevent the design from being deteriorated due to the use of only one operation panel among the plurality of operation panels with the special specification. It can be easily installed regardless of whether it is new or existing.
Since no special processing is required for this mounting, the installation cost can be reduced.
