Description

[Detailed description of the device]

[0001]

[Industrial applications]

 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]

[Prior art]

 Conventionally, for example, as described in Japanese Utility Model Laid-Open No. 63-113063 or Japanese Patent Application Laid-Open No. 2-147594, an operation panel in a car or an operation panel at a landing is provided on an entrance door of an elevator machine room. It has been proposed to attach a storage box for storing the key of the lock device to be used.

[0003]

[Problems to be solved by the device]

 By the way, recent buildings tend to be larger and taller, and it is common for multiple elevators to be installed in the building. However, in the conventional key storage device, it is sufficient for one building equipped with multiple elevators to have one operation panel in the car or an operation panel in the hall to which the key storage box is attached. Therefore, other units can be conventional ones, and only the control panel inside one car or the control panel at the hall will have special specifications. This imposes an extra burden on both the manufacturer and the user, and it is unfavorable in terms of design, because only one operation panel has a different shape. In addition, changing the operation panel in the car or the operation panel in the hall to the one with the key storage device in order to attach the key storage device to the existing elevator was not easy because special processing was required. .

The present invention has been made in view of the above-mentioned problems, and an object thereof is to provide a key storage device that does not require special equipment and can be easily installed regardless of new installation or existing installation. To do.

[0005]

Means for Solving the Problems To achieve this object, the present invention provides a key storage device for a cylinder lock device provided in a door knob having a large-diameter gripping portion and a small-diameter constriction portion. A chain body that is wound around the necked portion, a box body that is suspended at each end of the chain body and that has a lid that locks the end portion when closed, and a box in which the key is stored; It is equipped with.

[0006]

[Action]

 Since the present invention is configured as described above, when the key of the cylinder lock device is stored in the storage device, the chain is wrapped around the constriction of the doorknob, and the box is attached to each end of the chain. The lock is suspended and the key is stored in this box. Then, the lid of the box body is closed and the end portion is locked, and the grip portion of the door knob is prevented from coming off to prevent the chain body from coming out from the constricted portion. In this way, the key storage device can be arbitrarily installed on the door knob, so that no special device is required and it can be easily installed regardless of whether it is new or existing.

[0007]

【Example】

 Hereinafter, an embodiment of the key storage device of the present invention will be described with reference to the drawings. 1 is a perspective view showing an embodiment of the key storage device of the present invention, FIG. 2 is an exploded perspective view of a chain body and a box of the storage device of FIG. 1, and FIG. 3 is a cover of the box body of FIG. FIG. 4 is a perspective view showing an opened state, and FIG. 4 is a perspective view showing a state where the lid of the box body in FIG. 1 is closed.

As shown in FIG. 1, an entrance / exit door 1 of a machine room of an elevator has a door knob 2 having 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. And have.

Then, the key storage device of the cylinder lock device 3 of the present embodiment is suspended on the chain-like body, for example, the wire 4 wound around the constricted portion 2 a and each end of the wire 4. In addition, a box 6 having a lid 5 for locking the end portion when closed is provided, and this box 6 is provided with another box that can be locked and unlocked with a key provided in a management room (not shown), for example. A locking device 7 is provided. Further, as shown in FIGS. 2 and 3, engaging portions 4a and 4b are provided at the ends of the wire 4 described above, and the engaging portions 4a and 4b are slits 6a and 6b formed in the box body 6. It is designed to be inserted into. Further, the engaging portion 4b has a plurality of engaging positions, and is adapted to correspond to various diameters of the constricted portion.

In this embodiment, when the key (not shown) of the cylinder lock device 3 is stored in the storage device, the maintenance worker installs the wire 4 in the constricted portion 2b of the door knob 2 of the door 1 of the elevator machine room. The box body 6 is suspended by winding it and inserting the engaging portions 4a, 4b of the wire 4 into the slits 6a, 6b, and the key of the cylinder locking device 3 is stored in the box body 6. Next, the lid 5 of the box body 6 is closed to lock the engaging portions 4a and 4b, and the grip portion 2a is used as a stopper to prevent the wire 4 from slipping out of the constricted portion 2b. After that, another lock device 7 is locked by using the key provided in the control room.

In the embodiment thus configured, the key storage device can be arbitrarily installed on the doorknob 2, so that no special device is required and it can be easily installed regardless of whether it is new or existing. Can be done.

[0012]

[Effect of device]

 Since the present invention is configured as described above, there is no need for special equipment, such as a specially-designed operation panel, for storing the keys for the doors of the machine room. It is possible to prevent the burden from being imposed, and to prevent the deterioration of the designability due to the use of only one of the plurality of operation panels having the special specifications. In addition, it can be easily installed regardless of whether it is a new installation or an existing installation, that is, no special processing is required for this installation, and thus installation costs can be reduced.
