Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a key management device that manages and stores keys of specified persons.

[Conventional technology]

Conventionally, this type of key management device has been placed at the entrance of a building, for example, as part of a security system, to manage and store the keys of each room in the building.

That is, when a user enters a room, he or she brings a card with information written thereon that identifies him/her as the owner of the key, and the card is read by a card reader. As a result, if the read information is the same as the preset information, the door of the case storing the owner's key is opened.

Furthermore, when the owner leaves the room, the owner opens the case door, stores the room key, and locks the case door using the same operation as described above.

In this way, key management devices manage and store room keys every time someone leaves the owner's building, so the owner does not lose the key outside the building, and is attracting attention for its security. .

[Problem to be solved by the invention]

However, in the conventional key management device, the key storage case is made of a metal such as stainless steel, which makes the key storage case heavy. In particular, when a plurality of such key storage cases are arranged, the weight can be close to 100 kg depending on the number of cases, and the construction of this device requires a lot of manpower.

Furthermore, when a key storage case is manufactured from metal, it is expensive due to welding and hairline treatment for aesthetic purposes.

Furthermore, since the key management device is installed in an apartment complex or the like, decorations are required to suit the owner's taste.

However, since conventional key management devices are made of metal, they have the disadvantage that they cannot be easily decorated.

[Means to solve the problem]

The present invention has been made to solve these problems, and includes a key storage case made of a conductive plated resin material, a key switch that detects the presence or absence of a key stored in the key storage case, and a key switch that detects whether or not a key is stored in the key storage case. , a solenoid that releases the door of the key storage case, and a switch that detects the opening of this door.

Further, a plurality of key storage cases are arranged in the frame of the door, and a decorative frame made of resin is provided for each key storage case, and this is stored in the mounting position.

[For production]

By making the key storage case made of resin, the weight can be reduced.

Moreover, by providing a decorative frame, decoration becomes easy.

Moreover, FIG. 2 is a block diagram of a door in which a plurality of key storage cases shown in FIG. 1 are arranged. In the figure, 1 is the key storage case main body explained in FIG. 1, 10 is the door to which the key storage case main body l is attached, and 11 is a bezel corresponding to a decorative plate. Note that the key storage case body 1 and bezel 11 are connected by screws 12.
is fixed.

FIG. 3 is a block diagram of a key management device housing the door structure and card reader shown in FIG. 2. In the figure, 20
2 is the t-'' door body explained in FIG. 2, 21 is the cart reader that stores the control device, 22 is the hinge side flange, 23 is the bezel that is attached to the frame, and 24 is the door body 2.
This is a hinge part for attaching the base zel 23 to the bezel 23. Note that a key 25a for locking the door body 20 and the bezel 23 is a component for attaching the key 25. Also,
21a, 21b, 22a, 22b, and 24a are screws for assembling the above-described members.

FIG. 4 is a block diagram showing the construction of the key management device shown in FIG. 3. Here, wall mounting will be explained. In the figure, 31 is a concrete wall, 32 is a decorative wall painted on the concrete wall 31, 33 is a box for storing a key management device, and 33a is located inside the concrete wall 31 (not shown). The knockout hole 33b is for connecting with the conduit that has been installed through the screw 34b and the thread 34a.
C Take the vertical weight 34 (for installation, use the hole 33c
is a vertical reference line indicating the vertical position of the vertical weight 34.

Further, 23 is a bezel, 23a is a mounting hole for mounting the vertical weight 34 in the same manner as the mounting hole 33b, and 23b is a vertical reference line thereof. In addition, 23c.

23d and 33d are attached using screws.

Now, a housing section in which the box 33 can be stored is provided in the concrete wall, and the box 33 is stored as shown in FIG. At this time, the screw 34b and thread 34a are installed in the hole 33b.
A vertical weight 34 is attached via the vertical weight 34. And box 3
Adjust the position of 3 so that the position of the thread 34a is the vertical reference line 33e.
Arrange it so that After this box 33 is attached, the vessel 23 is attached to the box 33. In this case as well, as with the installation of the box 33, the installation is done through the hole 23a.
A vertical weight 34 is attached to the bezel, and the position of the bezel is adjusted so that the thread 34a of the vertical weight 34 reaches the vertical matching line 23b.

By these operations, the box 33 and bezel 23 can be placed perpendicular to the wall mounting position. Thereafter, the key storage case 1 etc. explained in FIG. 2 are attached.

In this way, the key management device in this embodiment operates in case 1a.
Since they are made of resin, the weight of the device can be extremely reduced even when a plurality of them are arranged as shown in FIG. As a result, the installation shown in FIG. 4 can be performed with less manpower and can be constructed at low cost. This reduction in weight makes it possible to arrange more key storage cases than before.

In addition, by applying conductive plating to the case 1a,
Even if the user is charged with static electricity, the static electricity can be discharged to the ground and will not adversely affect adjacent control circuits and the like.

Furthermore, by providing the decorative frame 11, it becomes possible to perform arbitrary decorations according to the owner's preference.

〔Effect of the invention〕

As explained above, in the present invention, since the key storage case is made of resin, the weight of the key management device can be significantly reduced. Thereby, it is possible to reduce the amount of manpower involved in the installation work, and the structure can be constructed at low cost. This reduction in weight makes it possible to arrange more key storage cases than before.

In addition, by applying conductive plating to the key storage, even if the user is charged with static electricity, the static electricity can be discharged to the ground, which has a negative impact on the control circuits etc. located adjacent to it. It will not cause any adverse effects.

Furthermore, by providing the decorative frame 11, it has excellent effects such as being able to carry out arbitrary decorations according to the owner's preference.
