Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus that automatically manages the lending and returning of keys using a card.

The lending and returning of keys to rental vehicles, company-owned vehicles and other vehicles, hotel room keys, etc. is usually managed by a single person in charge, and confirmation of lending and return is made by filling out a registration form. It is.

However, this method requires at least one key manager.

In order to securely manage the lending and return of keys unattended and to save labor, there is an automatic key management device using a card (for example, Japanese Utility Model Application No. 5586/1986).

This key management device consists of a box body that stores many types of keys to be managed, a large number of lock bodies arranged in line with each of the box bodies, and keys to be managed that are linked to each other in the lock body. A large number of auxiliary keys are inserted into the lock body, and one auxiliary key is inserted into the lock position 1.
A locking mechanism is provided for each lock body, a card insertion slot is provided in the box body, and the contents of the card inserted into the card slot are read and compared with internal information. , and a card reading verification circuit that issues a release command to the corresponding lock mechanism based on the verification result.

However, although this key management device is located at the front of the box (if a door is provided), this door is closed so that anyone can open and close it freely.

Therefore, if this key management device is applied to a building with many rooms, such as an apartment or a condominium (for example, to manage the keys of each wholesaler in a building), depending on whether or not a key is present, it will be possible to Even an outsider can easily know whether a person) is 0) or not.

For this reason, there is a drawback that a room in which no one is present is likely to be stolen, and the key owner cannot trust the key management device 1 to manage the key with peace of mind.

This invention makes it possible to reliably lend and return keys (d), which can be done unmanned, thereby saving labor.
This is to provide a key lending/returning management device that can be entrusted with the management of keys with peace of mind.

Embodiment 1 of the present invention will be described in detail below with reference to the drawings.

[Figs. 1 and 2] The control box 20 is installed at a predetermined location where key lending and return operations are to be managed. and is provided.

The operation unit 21 is located on the front left side of the management box 20, and the management unit 22
It stands out more than that.

The management section 221 is equipped with a hinged door 23 that covers the front surface of the management section 22 so as to be openable and closable.

An automatic door locking device 43 (see FIG. 8) is provided for this n23, and when the door 23 is closed, it is automatically locked by the automatic door locking device 431.

Also, as will be clear from what will be described later, the automatic door locking device 43 is unlocked in response to the reading result of the magnetic card 30 (see FIG. 3).

The door 231 is provided with a handle 24 and an emergency unlocking device 25.

The emergency unlocking device 25 unlocks the door 2 using an emergency key if the automatic door locking device 43 does not unlock for some reason.
This is for opening 3.

Operation unit 211 Inside the box 20 Magnetic card reader 26
(see Figure 8), and its scanning groove 2 is provided on the front surface.
γ is in the form.

This card reader 26 is of a manual scanning type, and reads the contents recorded on the magnetic stripe 30a1 by scanning the magnetic card 30 downward once through the scanning groove 2γf.

On the magnetic stripe 30a1 are magnetically recorded a card number code, company identification code, card owner identification code, expiration date, and if necessary, a key number code.

Further, on the front surface of the operation section 21, there are provided an available indicator light 28 indicating that lending or returning is possible, and an available Komachi indicator light 29 indicating that lending or returning is not possible.

As shown in FIG.
Management members) 321 are connected.

The management key 32 has a cylindrical portion 33, and a retaining protrusion 34 and an engaging protrusion 35 that protrude outwardly and inwardly from the distal end of the cylindrical portion 33, respectively.

In this embodiment, a large number of keys 31 are managed, and a large number of insertion holes 3γ into which such management keys 32 are inserted are formed in the right half of the management section 22 of the management box 20.

The insertion holes 3γ are arranged regularly, and one pair of management keys 321 corresponds to one pair of the management keys 321.

By changing the diameter, wall thickness, actual size and shape of the cylindrical portion 33 of the management key 32, each management key 32 can be inserted into its corresponding insertion hole 3γ1.

Rental key designation push button switches 38 for designating keys to be rented are provided and arranged corresponding to each of these insertion holes 3γ.

This pushbutton switch 38 is preferably of an illuminated type.

A processing completion indicator light 39 is also provided on the front surface of the management section 22 to indicate that the lending or return processing has been completed.

It is preferable that one location near the indicator light 39 has a message such as "Please close the door" displayed thereon.

The left half of the management section 22 is provided with a printer 40, a power switch 41, and a power-on indicator light 42.

The printer 40 is used to print and record lending and return items, including items such as lending or return, borrower or returner, key number, and date and time if necessary.

Details of the insertion hole 3γ in the management section 221 of the management box 20 and the locking device 53 (see FIG. 8) provided inside the insertion hole 3γ are shown in FIGS.

The insertion hole 3γ is formed by a keyhole member 45 attached to the front plate 22a1 of the management section 22, and the keyhole member 45 consists of front and rear halves 45A and 45B.

The front half-rest 45A is formed with a circular hole having a diameter to accommodate the cylindrical portion 33 of the management key 32, and a recess 46 through which the retaining protrusion 34 passes is formed in the upper part of the circular hole.

The center of the circular hole in the front half 45A is located in the axial direction (this groove 4
A rotatably supported shaft 47 is located thereon, and one insertion hole 31 is formed in an annular shape by the shaft 47 and the circular hole of the front half 45A.

A rear half hole 45B1 of the keyhole member 45 is formed with a circular hole having a diameter that allows the cylindrical portion 33 to rotate including the one locking protrusion 34 when the cylindrical portion 33 of the management key 32 is inserted. There is.

The shaft 4γ passes through the center of the circular hole in the rear half-rest 45B.

A disc-shaped cam 49 is fixed to the shaft 4γ, and one peripheral edge of this cam 49 has a locking recess 49a and one recess 1all.
a guide curved surface 49b that is curved one direction from the upper end of one wall forming the i49a toward the center and has a concave portion 49c;
A convex portion 4 protruding from the end of the concave portion 49c of this curved surface 49b.
9d, and a position detecting recess 49e formed by connecting the protrusions 1,4,9a1.

The tip of the lock partner 50 in the direction E perpendicular to the axis 4γ is inserted into the recess 49c.

The lock partner 50 is locked in its longitudinal direction E by a solenoid 51.
This is driven forward and backward.

The rod 50 is normally biased by a spring so that its tip comes into contact with the circumferential surface of the cam 49, and when the solenoid 51 is energized, the rod 50 moves back one step in the direction away from the circumferential surface of the cam 49. Move away from the surrounding surface.

Further, one peripheral surface of the cam 49 is in contact with a lever of a microswitch 52 for detecting a locking position.

When the management key 32 is pulled out from the insertion hole 31 and in the state of C(rN), the recess 46 and the groove 48 of the shaft 4γ face each other, and the tip of the locking rod 50 enters the recess 49c of the curved surface 49b of the cam 49. I'm here.

When the cylindrical portion 33 of the management key 32 is inserted into the insertion hole 3T, the retaining protrusion 34 of the key 32 passes through the recess 46, and the engaging protrusion 35 fits exactly into the groove 481 of the shaft 4γ. The protrusion 34 is located on the inner side of the keyhole member 45, that is, on the rear half-rest 4.
It reaches one hole in the circular hole of 5B.

Then, when the management key 32 is rotated approximately 90 degrees from the rental position Rotate one direction.

Therefore, the tip of the locking side bar 50 moves back from the concave portion 49° C. to the curved surface 4-9b, and finally enters the concave portion 49a once.

Since the wall of the recess 49a is approximately straight in the radial direction, once the tip of the rod 50 is inserted into the recess 49a, it is no longer possible to rotate the cam 49 in either the left or right direction. It becomes possible.

In this state, the locking protrusion 34 of the management key 32 is at the return position, and even if you try to pull out the key 32, the protrusion 34 will hit the inner surface 45a of the front half 45A of the keyhole member 45, so the key 32 will be pulled out. It is also impossible.

In addition, the tip of the lever of the micro switch 52 is a rotating part, 49e
1, the microswitch 52 is turned on and it is detected that the door is locked.

When the solenoid 51 is energized, the locking rod 50 is moved back and its tip is removed from the recess 49a of the cam 49, so that the cam 49 can rotate.

At this time, when the management key 32 is returned from the return position Y to the rental device X1, the projection 34 of the key 32 aligns with the recess 46+
It becomes a Noh performance.

As the key 320 rotates, the cam 49 also rotates and returns one position to its original position, so when the energization to the solenoid 51 is stopped, the lock side rod 50 advances and its tip enters the recess 49c1.

In addition, the microswitch 5 has no rotation of the cam 49.
Since the tip of the lever No. 2 comes out from the recess 1N9e, the switch 52 is turned off.

FIG. 8 shows a schematic configuration of the electric circuit of the rental and return management device.

This electric circuit is built into the management box 20.

Read signal from card reader 26, key designation signal from pushbutton switch 38 and microswitch 52
A lock detection signal from the control unit 541 is sent to the control unit 541.

This controller 541 controls the printer 40, automatic door locking device 43, and solenoid 51.

As the control unit 54, for example, a microprocessor is used.

Management of key lending and return is performed in accordance with the procedure shown in FIG.

This figure mainly shows the control operation based on the control E1354t.

First, it is determined whether the card 30 has been inserted into the scanning groove 27 (step 1).

This judgment is made based on a detection signal from a card insertion detector (as shown) provided within the scanning groove 2.gamma..

When the card 30 is inserted, the card reader 26 reads the contents written on the magnetic stripe 30a1 of the card 30 (step 2).

Then, the read card data (for example, card number, etc.), date and time, etc. are printed by the printer 401 (step 3).

Cards that are not genuine cards, such as cards whose expiration date has passed (even if this happens, print in step 3).

Information regarding date and time can be obtained, for example, from the output of a date setter or a clock (as shown) provided in the management box 20.

Next, it is determined whether the inserted card is a legitimate card based on the card data read the next time (step 4).

For example, a card whose expiration date has passed or a card with the same number as an invalid card number stored in the memory of the control unit 54 is considered not to be a legitimate card.

If the card is not a legitimate card, the used Komachi indicator light 29 is turned on (step 18), and the process is terminated.

If the card is a legitimate card, the process moves on to step 5I and lights up the usable indicator light 28, unlocking the door automatic locking device 43 and making it possible to open the door 23 (step 6).

After this, the door 23 is opened (step γ), and it is checked whether any of the pushbuttons/switches 38 for specifying a key has been pressed (step 8).

If any pushbutton switch 38 is pressed, the key is lent, and the process proceeds to step 91; if not, the key is returned, and the process proceeds to step 131.

In the case of lending a key, the pressed pushbutton switch 3
81 Corresponding solenoid 511 is energized and management key 3
2 is unlocked (step 9).

Then, the management key 32 is turned from the return position Y to the lending position X1, and the microswitch 52 is turned off.

Based on the output 1 of this micro switch 52, it is determined whether the management key 32 has been pulled out (step 1).
0), if the microswitch 52 is off 1, the printer 401 prints out the fact that the key is being lent and the number of the key to be lent (step 11).

Then, the processing completion indicator light 39 is turned on.

In the case of returning the key, the management key 32 is inserted into the insertion hole 371 and rotated from the rental position Check whether the management key 32 is locked (step 13), and if it is locked, the printer 40 prints out the fact that the key is being returned and the number of the returned key (step 11), and then prints out the process completion indicator light 39. (Step 12).

When the lending or return is completed, the door 23 should be closed, so check whether the door 23 is closed (step 14), and if it is closed, lock the door 23 using the automatic door locking device 431 (step 14). 15) End the process.

If the door 23 is not closed, it is determined whether a certain period of time or more has elapsed (step 16), and if so, an alarm buzzer (as shown) is sounded (step 17).

If the predetermined time has not elapsed or after the buzzer sounds (step 14), return and repeat steps 14, 16, and 17 until the door 23 is closed.

Although a magnetic card is used in the above embodiment, a perforated card or the like may also be used.

Also, instead of unlocking the management key of the specified key by inputting the key specification from the key specification push button switch, record the number of the key to be lent on one card, and use this number to record the number of the key to be lent. Therefore, you can also set it so that only specific keys can be borrowed.

As mentioned above, 1. Invention 1. According to this, card reading result 1.
The key management components are locked and unlocked accordingly.
The lending and returning of keys can be managed unmanned and reliably.

Therefore, there is no need for a key custodian, making it possible to save labor.

Furthermore, by storing the card numbers of lost cards and other invalid cards in advance, it is possible to prevent unauthorized borrowing of keys using such invalid cards.

Furthermore, in this invention, a locking device is provided on one door for closing the storage section of the key management member in the management box 1, and this locking device is unlocked according to the card reading result. There is.

Therefore, this door is normally closed and can only be opened by the person who has the card, that is, the person who is qualified to lend and return the key.

For this reason, other people, that is, outsiders, cannot know the presence or absence of each key, and the presence or absence of each room etc. is not known, so you can leave the keys to the management with peace of mind without inviting theft etc. be able to.
