Further after completion of the operation of the timer, the device 5 sends a signal to the drive device to switches polarity of power thereby to retract the rod 19, returning the body 4 to its initial position. Consequently, depth of the body can be made smaller and the key can be easily put in or taken out and assembling can be easily performed.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a key management device for centrally managing keys used for entering and leaving each room in a condominium, office building, etc.

[0002]

2. Description of the Related Art Conventionally, for example, an embodiment shown in FIG. 8 is known as a management device of this type. That is, 50
Is a main body of the apparatus, and the main body 50 of the apparatus is provided with a plurality of key accommodating portions 51 aligned in the vertical and horizontal directions. Each key storage portion 51 is formed in a box shape, and an opening / closing door 53 is pivotally mounted on the front surface of the panel 52.

Reference numeral 54 is a lock device for the keys 55 which are respectively installed in the respective key storages 51. This key lock device 54
A required space 56 is provided between the front surface 54a of the door and the opening / closing door 53 so that the key 55 can be pulled out from the lock device 54 by inserting a hand.

Reference numeral 57 is a control device which is provided in the device main body 50 or the manager's room and controls each of the key lock devices 54. The control device 57 is electrically connected to a display device 58 installed in the upper part of the device body 50 and a card reader 59 provided in the central part of the device body 50.

In the above structure, when a magnetic card (not shown) is inserted into the card insertion slot of the apparatus body 50, the card reader 59 reads the contents of the card and sends the identification information to the controller 57. The control device 57 causes the determination unit 60 to determine whether the magnetic card is a legitimate one, which key storage unit 51 matches the card contents, and the like, and the contents of the magnetic card and the registration information of the memory unit 61 are determined. When they coincide with each other, the indicator lamp of the display device 58 is turned on, the lock of the key lock device 54 of the key storage portion 51 corresponding to the contents of the card is unlocked, and the opening / closing door 53 is automatically opened.

Then, the user puts his / her hand in the required space 56 of the key storage portion 51, first turns the key 55 in the unlocking direction, and then pulls out the key from the key lock device 54.

However, the above structure has the following drawbacks. Since the required space 56 has to be provided in the key storage portion 51, the depth D of the device main body 50 becomes deep. Therefore, the device body cannot be made compact. When pulling out the key 55 from the lock device 54, it is necessary to put the hand in the required space 56 and to turn to the unlocked position with the key 55 gripped, so not only is the operation troublesome, but also the front face. The area of each opening / closing door 53 pivotally attached to the panel 52 cannot be reduced. Therefore,
It is not possible to provide a desired large number of key storages on the panel 52 having a predetermined size of the apparatus body 50. Not only is it troublesome to assemble, since each key lock device 54 for locking each key 55 and each lock mechanism for locking each opening / closing door 53 are required.
I can't make it cheaply.

[0008]

In view of the above-mentioned conventional drawbacks, the present invention makes it possible to effectively utilize the space of the key storage body to make the depth of the apparatus main body shallow, and to make it easier for the user. It is very easy to use, and it is possible to provide a large number of key housings in the main body of the device while effectively utilizing a predetermined front panel, and further, to obtain an inexpensive key management device which is easy to assemble. In addition, another object is to obtain a key management device that can automatically close the key storage body that is rotated outward from the front panel.

[0009]

The key management device of the present invention comprises:
A box-shaped device body 1, a plurality of openings 3 formed in a lattice on a front panel 2 of the device body 1, and a pivotally supported device body 1 so as to be able to close each of these openings 3. In addition, a plurality of key housings 4 having a front wall 10a that is substantially the same vertical surface as the front panel 2 and a control device 5 provided at an appropriate place behind the key housings 4 are provided. A plurality of drive devices 6 which are driven based on a control command signal to open and close each of the key housings 4 individually.

In the above structure, the driving device 6 is a magnet motor in which the operating rod 19 moves back and forth in the axial direction of the motor body, and the tip end 19a of the operating rod 19 is located behind the key storage case body 10. It is appropriately pivoted to the wall 10b. Further, the control device 5 is connected with a timer circuit that keeps the key housing 4 open for a required time when the user takes out the key from the key housing 4.

[0011]

When the user inserts the identification card into the card insertion slot of the apparatus main body, the input device sends the card contents of the identification card to the control device. The control device outputs the sent information signal to the determination unit. If the identification card is correct, the determination section determines the key storage body corresponding to the contents of the card for which a matching match has been obtained, and notifies the control device of the determination result. The control device outputs a drive signal to the drive device selected based on the result of this determination. Then, the polarity changes via the power source of the drive device, and the operating rod extends. Therefore, when the operating rod of the drive device is extended, the key storage body rotates to the outside of the device body by a required amount. This opens the opening of the front panel. Therefore, the user puts his / her hand in the key storage body and takes out the stored key as it is. In this way, after the user takes out the key from the key housing, when the signal is sent from the control device to the drive device automatically or by the push button type switch, the polarity of the power supply for the drive device is switched and its operation The rod expands and contracts, and the key housing returns to the original closed position.

The present invention will be described in detail below with reference to the embodiments shown in the drawings. 1 to 7, reference numeral 1 denotes a box-shaped device body. The depth of this device body is generally shallower than this type of device body. Reference numeral 2 is a front panel of the apparatus body 1. Except for a part on the right side, the front panel 2 is formed with vertically long openings 3 in a vertically and horizontally aligned state (lattice shape). The total number of openings 3 is 50, but this number can be increased or decreased as necessary.

Thus, the device body 1 is provided with a plurality of key housings 4 which are closed with the respective openings 3 and have a front wall which is substantially the same vertical surface as the front panel 2, respectively. It is pivotally supported. In addition, a control device that outputs a control command signal to open and close the opening 3 of each key housing 4 with respect to the front panel 2 is provided in the device body 1.
A plurality of drive devices 6 and the like which are driven based on a control command signal from the device and which directly or indirectly open or close each of the key housings 4 are incorporated. Further, the control device 5 includes a card reader 7 as an example of an input device that is input by a user of a key (insertion of an identification card, operation of inputting a personal identification number, etc.) A display unit 8 for indicating whether or not to store in 4 is electrically connected.

Therefore, the key housing 4 and the driving device 6 which are the main parts of the present invention will be described first.

As shown in FIGS. 1 to 4, the key housings 4 are individually arranged in the vertical direction, so to speak, the front panel 2.
It constitutes a part of the door for each key storage provided in the.
That is, 10 is a vertically long key storage case main body having a front wall 10a that is substantially the same vertical surface as the front panel 2 and having an opening at the top. The opening 3 is rotatably supported by a horizontal shaft 11. The rear wall 10b of the key storage case body 10 is slightly shorter than the front wall 10a. The left and right side walls 10c of the key storage case body 10 are formed to be shorter than the rear wall 10b. The horizontal axis 11 is the internal frame 12 of the apparatus body 1.
It is mounted on a horizontal shaft.

Reference numeral 13 denotes a key case detachably provided in the key storage case body 10, and the upper end portion of the key case 13 projects from the left and right side walls 10c of the key storage case body 10. The key user is, for example, the key case 13
The key can be pulled out from the key storage case main body 10 to take out the stored key. Therefore, the key case 13 is convenient for taking out the key, but is not an essential requirement of the present invention. The key may be placed in the key storage case body 10 as it is, or the key case 13 of an appropriate shape may be provided integrally with the key storage case body 10 so that the key can be easily extracted.

The drive device 6 is disposed behind the key storage case body 10 as shown in FIG. As an example of the drive device 6, a magnet motor is used in which the operating rod moves back and forth in the axial direction of the motor body.

By the way, the structure of the magnet motor 6 will be briefly described with reference to FIG. 5. Reference numeral 15 is a motor body fixedly provided in the inner frame 12 so as to be located behind the key storage case body 10. is there. This motor body 1
A magnet 16 is fixedly installed inside the inner peripheral portion of the magnet 5, and a cylindrical rotor 17 is provided inside the magnet 16. 18 is a center guide tube that supports the rotor 17,
An operating rod 19 that slides forward and backward in the axial direction of the motor body 15 is slidably fitted into the center guide cylinder 18.
The operating rod 19 has a key storage case body 1 at its tip portion 19a.
Central part of the rear wall 10b of 0 (including a part from the central part)
It pivots appropriately, and moves forward and backward when the polarity of the power source for the driving device is switched. Therefore, this magnet motor 6
Unlike a general motor whose output shaft rotates, it may not be called a "motor" originally, but in this specification, a magnet type in which the output shaft (operating rod) moves back and forth in the axial direction of the motor body. For the sake of convenience, this driving device is referred to as a "magnet motor".

Next, the control device 5 will be described. In the present embodiment, the control device 5 is appropriately incorporated in the device main body 1, but it is not always necessary to mount the control device 5 on the device main body 1 and may be installed in, for example, a manager's room.

As shown in FIG. 7, the device body 1 is electrically provided with a card reader 7 as an example of an input device which is input by a user of a key (insertion of an identification card, operation of inputting a personal identification number, etc.). Connected to. Therefore, a card insertion port 20 for an identification card (such as an ID card or a card having a bar code) is provided at an appropriate position on the front panel 2 of the device body 1 in correspondence with the position of the input device 7. Of course, as another example of the input device 7, a so-called numeric keypad may be provided separately or in combination.

Further, the control device 5 is electrically connected with a display section 8 for displaying in which key housing 4 the user's relevant key should be housed, in which key housing 4 it is housed, and the like. There is. Therefore, lighting lamps 21 are provided at appropriate positions on the front panel 2 of the apparatus body 1 in correspondence with the number of the key housings 4. Further, the magnet motors 6 provided laterally in the openings 3 of the apparatus body 1 are electrically connected to the control device 5 via the respective power sources 22 for polarity conversion. In addition, 23 is a memory unit provided with a program necessary for the operation of this device, 24 is a determination unit for comparing and comparing the input signal from the input device 7 with the registration information of the memory unit, and 25 is a key for the user. Is a timer circuit that keeps the key housing 4 open for a required time when the key is taken out of the key housing 4.

In the above configuration, one mode in which the user takes out the key stored in the key storage 4 will be described.

First, the user inserts the identification card into the card insertion slot 20 of the apparatus main body 1. Then, the input device 7 sends the card contents (identification information) of the identification card to the control device 5. The control device 5 outputs the sent information signal to the determination unit 24. The determination unit 24 compares and collates the registration information preset and registered in the memory unit 23 corresponding to each key housing 4 with the card content (identification information) read by the card reader 7 as an input device, and the identification is performed. If the card is correct, the key storage body 4 corresponding to the content of the card for which the matching is obtained is discriminated, and the determination result is notified to the control device 5. The control device 5 outputs a drive signal to the magnet motor 6 side selected based on this determination result. Then, the polarity of the magnet motor 6 changes via the power source 22, and the operating rod 19 extends.

Next, when the operating rod 19 of the magnet motor 6 is extended, as shown in FIG. 6, the key storage case body 10 of the key storage body 4 has a required amount outside the apparatus body 1 with the horizontal axis 11 as a fulcrum. Then it rotates 25 degrees). As a result, the opening 3 of the front panel 1 is opened. At this time, the timer circuit 25 that keeps the key housing 4 open for the required time starts.

Then, the user pulls out the key case 13 from the key storage case body 10 by picking it with his / her finger, and further takes out the stored key. In this case, when the key is stored in the key storage case body 10 as it is, or when the key case 13 is provided integrally with the key storage case body 10, the key is directly extracted from the key storage case body 10.

After the user takes out the key from the key housing 4 in this way, the control device 5 sends a signal to the drive device side after the timer of the timer circuit 25 ends. Then, the polarity of the power source 22 is switched, the operating rod 19 of the magnet motor 6 expands and contracts, and the key housing 4 returns to the original position. When the key housing 4 returns to its original position, its front wall 10a becomes the same vertical surface as the front panel 2.

In the above-mentioned embodiment, it is explained that the key housing 4 returns to the original closed position after the timer of the timer circuit 25 ends, but the timer circuit 2 is not always necessary.
It is not necessary to use 5, and for example, a switch for closing the key housing 4 such as a push button may be provided on the front panel 2 of the device body 1 and this switch may be electrically connected to the control device. Further, an internal detector for detecting whether or not the key is stored can be appropriately attached to the key storage body 4, and this internal detector can be connected to the control device to automatically close the key storage body 4. You may do it.

Further, in the above-mentioned embodiment, it is explained that the opening 3 of the front panel is formed in a vertically long shape and the key is put into the vertically long key storage body 4, but the opening 3 is horizontally long. It may be. Therefore, in this case, the form of the key housing 4 is inevitably a drawer type, and the drawer type key housing opens and closes on the basis of the front panel 2 from the operating rod 19 of the drive device 6.

[0029]

As is clear from the above description, the present invention has the following effects. (1) The front wall 10a of the key housing 4 is, so to speak, the front panel 2
Since it constitutes a part of the above, it is possible to effectively utilize the space of the key storage body. Therefore, the depth of the device body can be reduced (the device body can be made compact). (2) When inserting a key into the key housing 4, simply put the key in the key housing 4
On the other hand, when removing the key from the key storage body 4, it is sufficient to put a hand into the key storage body 4 and take out the stored key as it is. Therefore, it is very easy for the user to use. (3) Since the key housing 4 is pivotally supported by the device body 1 so as to close each of the plurality of openings 3 formed in the front panel 2, the front panel of a predetermined size can be effectively utilized. However, a large number of key storage bodies can be provided in the main body of the apparatus. (4) It is sufficient to dispose the key housing driving device that is driven based on the control command signal from the control device 5 in the rear of each key housing 4 in the device body. That is, since a lock mechanism for locking the open / close door 53 is not required unlike the conventional example, a simple and inexpensive key management device can be obtained. (5) When the timer circuit 25 or the switch for closing the key housing 4 of the apparatus main body 1 is connected to the control device 5, the key housing which is rotated outward from the front panel can be automatically closed. (6) The drive device 6 is a magnet motor in which the operating rod 19 moves back and forth in the axial direction of the motor body.
In the case of the embodiment in which the front end portion 19a of the key housing is appropriately pivoted to the rear wall 10b of the key storage case body 10, if the opening / closing mechanism of the key storage body (key storage case body) 4 can be simplified. Since the stroke of the operating rod 19 can be sufficiently obtained, the key housing body (key housing case body) 4 can be opened to a desired angle.
