It is a front view of the locking / unlocking device 10. It is a right side view of the locking / unlocking device 10. It is a rear view of the locking / unlocking device 10.

Hereinafter, the locking / unlocking device 10 according to the present embodiment will be described in detail with reference to the drawings. FIG. 1 is a front view of the locking / unlocking device 10, FIG. 2 is a right side view of the locking / unlocking device 10, and FIG. 3 is a rear view of the locking / unlocking device 10.

<Overall configuration>
First, the overall configuration of the locking / unlocking device 10 will be described.

The locking / unlocking device 10 has a lock 14 that can be moved from one of the unlocking position and the locking position to the other by the key 12, and unlocking the lock 14 when a predetermined code is set when the lock 14 is in the locking position. It is configured to have a dial lock 16 capable of moving to a lock position, and a string-shaped body 18 having one end attached to the locking / unlocking device 10 and a key 12 attached to the other end.

Further, as shown in FIG. 3, a ring-shaped pulley 20 is rotatably attached to the locking / unlocking device 10 with screws 22 on the back surface of the locking / unlocking device 10, and the string-shaped body 18 is attached to the pulley 20. It is attached to the locking / unlocking device 10 via.

Although the details will be described later, in this locking / unlocking device 10, one end of the string-shaped body 18 is passed through the handle of a luggage (carry bag, bag, etc.), and then one end of the string-shaped body 18 is locked / unlocked with the key 12. It is a lock / unlock device that can be used, and can be applied as a device for temporarily depositing luggage (carry bags, bags, etc.) at airports, stations, and the like.

<Lock>
Next, the lock 14 of the locking / unlocking device 10 will be described.

The "lock" according to the present invention may be a lock that can be moved from one of the unlocking position and the locking position to the other by a key, and the type and structure thereof are not particularly limited, but in this example, the lock 14 is outside. A disc tumbler type cylinder lock having a cylinder 14a and an inner cylinder 14b is applied.

The outer cylinder 14a of the lock 14 is fixed to the main body of the locking / unlocking device 10, and the inner cylinder 14b is rotatably arranged in the inner space of the outer cylinder 14a with respect to the outer cylinder 14a. The inner cylinder 14b is formed with a keyhole 14c having a rectangular front view into which the key 12 of the lock 14 can be inserted. Further, inside the lock 14, a plurality of discs (not shown) are arranged so as to cross the outer cylinder 14a and the inner cylinder 14b.

When the key 12 is not inserted into the keyhole 14c, the disc is pushed by a spring (not shown) and is located across the boundary between the outer cylinder 14a and the inner cylinder 14b, so that the inner cylinder 14b is located with respect to the outer cylinder 14a. It becomes a state where it cannot rotate. On the other hand, when the key 12 whose key code (unevenness engraved on the key 12) matches is inserted into the keyhole 14c, the unevenness of the key 12 moves (rotates) the disk, so that the disk moves (rotates) to the inner cylinder 14b. The inner cylinder 14b is accommodated and can freely rotate with respect to the outer cylinder 14a.

The inner cylinder 14b can be moved to the locking position by rotating in the locking direction (counterclockwise in this example) by the key 12 when it is in the unlocking position, and is unlocked by the key 12 when it is in the locking position. It can be moved to the unlocked position by rotating in the direction (clockwise in this example). That is, the inner cylinder 14b can be moved from one of the unlocking position and the locking position to the other by the key 12.

Here, the "unlocking position" of the lock 14 is a position where the key 12 can be removed from the lock 14, and in this example, as shown in FIG. 1, one of the keyholes 14c in the longitudinal direction is unlocked. It is a position facing the direction of the character "OPEN" applied to the main body of the lock device 10. At this unlocking position, the key 12 is configured so as not to be locked to the inner cylinder 14b and the outer cylinder 14a, so that the key 12 can be freely inserted and removed from the lock 14.

On the other hand, the "locking position" of the lock 14 is a position where the dial lock 16 restricts the movement of the lock 14 to the unlocking position, and is a position where the key 12 cannot be removed from the lock 14. In this example, one of the keyholes 14c in the longitudinal direction is a position facing the direction of the character "LOCK" provided on the main body of the locking / unlocking device 10. At this locked position, the tip of the key 12 is configured to be locked to the outer cylinder 14a, so that the key 12 cannot be removed from the lock 14.

The structure and method for making the key 12 unable to be removed from the lock 14 at the locked position are not limited to this example, and are inserted into the keyhole 14c by locking the key 12 with the inner cylinder 14b, for example. The key 12 may not be removed from the lock 14, or the key 12 inserted into the keyhole 14c may be disabled from the lock 14 by locking the key 12 with another member (disk or the like).

<Dial lock>
Next, the dial lock 16 of the locking / unlocking device 10 will be described.

The "dial lock" according to the present invention may be any dial lock that enables movement to the unlocking position of the lock when a predetermined code (password, etc.) is set when the lock is in the locking position. The type and structure thereof are not particularly limited, but in this example, a conventionally known number matching lock is applied as the dial lock 16.

The dial lock 16 can freely set (remember) a predetermined code (in this example, a password consisting of a combination of numbers) when the lock 14 is in the unlocked position, and the lock 14 is in the locked position. At a certain time, the lock 14 can be moved to the unlocking position by setting a predetermined code stored in the unlocking position. The dial lock 16 includes a slider 16a made of a plate-shaped member that can slide in the longitudinal direction in conjunction with the rotation of the inner cylinder 14b of the lock 14.

When the inner cylinder 14b rotates in the locking direction (counterclockwise), the slider 16a of the dial lock 16 moves (slides) in the locking direction (in this example, the left side in the horizontal direction) in conjunction with the rotation of the inner cylinder 14b. ) And move from the unlocked position to the locked position.

When the slider 16a is in the locking position, if the predetermined code stored in the unlocking position is not set, the slider 16a is moved (sliding) in the unlocking direction (horizontal right side in this example). Is regulated, so that the rotation of the inner cylinder 14b interlocked with this is also regulated. That is, since the dial lock 16 (slider 16a) cannot be moved (sliding), the movement of the lock 14 (inner cylinder 14b) to the unlocking position is restricted.

On the other hand, when the slider 16a is in the locking position and a predetermined code stored in the unlocking position is set, the slider 16a can be moved in the unlocking direction (horizontal right side). When the inner cylinder 14b is rotated in the unlocking direction (clockwise) by the key 12, the slider 16a linked to the inner cylinder 14b moves in the unlocking direction (horizontal right side), and moves from the locking position to the unlocking position.

When the slider 16a moves from the locking position to the unlocking position, the predetermined code stored in the unlocking position is automatically reset to the initial code (“0000” in this example), and in this state, a new predetermined code is newly determined. The lock 14 is configured so that it cannot be rotated in the locking direction unless the code (password) of is set (stored).

<String-like body>
Next, the string-shaped body 18 of the locking / unlocking device 10 will be described.

The "string-like body" according to the present invention may be a string-like body having one end attached to the locking / unlocking device and a key attached to the other end, and the material thereof is not particularly limited. A flexible wire is applied as the string-shaped body 18.

As shown in FIG. 2, one end side of the string-shaped body 18 is attached to the back surface of the main body of the locking / unlocking device 10 via the pulley 20, and the key 12 of the lock 14 is attached to the other end side. Needless to say, the key code of the key 12 (the unevenness engraved on the key 12) is a key code that matches the lock 14 (a key code in which the inner cylinder 14b can freely rotate with respect to the outer cylinder 14a). ..
<Example of using the locking / unlocking device>

Next, an example of using the locking / unlocking device 10 will be described.

First, when a user deposits luggage (carry bag, bag, etc.) in the lock / unlock device 10, it is necessary to find an unused lock / unlock device 10. Here, whether or not the locking / unlocking device 10 is in an unused state is determined by the position where the key 12 inserted into the keyhole 14 faces the direction of the character "OPEN" applied to the main body of the locking / unlocking device 10. It is easy to do so (the inner cylinder 14b of the lock 14 is in the unlocked position), the key 12 is pulled out from the lock 14, and the string-like body 18 is in an unused state. You can judge.

Subsequently, the user removes the key 12 if the key 12 is inserted in the keyhole 14 (if the key 12 is not inserted in the keyhole 14, picks up the string-shaped body 18) and then carries the luggage. A hand or the like is passed through the string-shaped body 18, the key 12 attached to the string-shaped body 18 is inserted into the keyhole 14c of the lock 14, and the luggage is set in the locking / unlocking device 10.

Subsequently, the user operates the dial lock 16 to set an arbitrary code (password), and then uses the key 12 to rotate the lock 14 in the locking direction (counterclockwise), whereby the dial lock 16 is used. Since the movement of the lock 14 to the unlocking position is restricted and the key 12 cannot be removed from the lock 14, luggage can be temporarily stored.

In the unlocking device 10 in the unused state, the code of the dial lock 16 is reset to the initial code ("0000" in this example), and in this state, a new code (password) is set (stored). ), The lock 14 is configured so that it cannot be rotated in the locking direction (counterclockwise). Therefore, the user must always set the code (password) by operating the dial lock 16, and the user will not forget to set the code (password).

Further, when an arbitrary code (password) is set by operating the dial lock 16 and the lock 14 is rotated in the locking direction (counterclockwise) by the key 12, the code is automatically set to the initial code ("0000"). ), So the code (PIN) set by the user does not remain displayed on the dial lock 16, and the code (PIN) is known to a third party. There is no fear of getting lost.

When the user temporarily receives the checked baggage, the dial lock 16 is operated to set the code (password) set by the user, and the lock 14 is unlocked by the key 12 (clockwise). ), Since the key 12 can be pulled out, the baggage can be received by removing the handle or the like of the baggage passed through the string-shaped body 18. When the inner cylinder 14b of the lock 14 moves to the unlocking position, the code is automatically reset to the initial code (“0000”) so that the next user does not forget to set the code (password). Will be done.

As described above, the locking / unlocking device (for example, the locking / unlocking device 10 shown in FIG. 1) according to the present embodiment is shown in the unlocking position (for example, FIG. 1) by the key (for example, the key 12 shown in FIG. 1). , The longitudinal direction of the key hole 14c is toward the direction of the character "OPEN" applied to the main body of the locking / unlocking device 10) and the locking position (for example, the longitudinal direction of the key hole 14c is applied to the main body of the locking / unlocking device 10. A lock that can be moved from one side to the other (for example, the lock 14 shown in FIG. 1) and a predetermined code (for example, the lock 14 shown in FIG. 1) when the lock is in the lock position. A locking / unlocking device including a dial lock (for example, the dial lock 16 shown in FIG. 1) that enables the lock to be moved to the unlocking position when a password) is set, and one end side thereof. When a string-like body (for example, the string-like body 18 shown in FIG. 1) attached to the locking / unlocking device and to which the key is attached is provided on the other end side, and the lock is moved to the unlocking position by the key. When the key can be removed from the lock and the lock is moved to the locking position by the key, the dial lock restricts the movement of the lock to the unlocking position and the key is moved from the lock. It is a locking / unlocking device characterized in that it cannot be pulled out.

According to the locking / unlocking device 10 according to the present embodiment, no member other than the device is required, the installation is easy, and the degree of freedom of the installation location can be increased.

The locking / unlocking device is provided with a rotatably arranged pulley (for example, the pulley 20 shown in FIG. 3), and one end side of the string-like body is attached to the locking / unlocking device via the pulley. You may be.

With such a configuration, the load applied to the end of the string-shaped body can be released by the rotation of the pulley, and the life of the string-shaped body can be extended as compared with the case where the string-shaped body is fixed to the device with screws or the like. In addition to being able to extend, it is possible to prevent problems such as the string-like body coming off the device. In addition, it is possible to improve the convenience of the user by preventing the string-like body from being twisted.

Further, the pulley may be arranged on the back surface of the locking / unlocking device.

With such a configuration, by installing the device on a wall surface or the like, one end of the string-like body can be hidden between the wall surface or the like and the back surface of the locking / unlocking device, so that the string-like body is intentionally removed. Is difficult, and the security of the device can be improved.

Further, the lock is a cylinder lock having an outer cylinder (for example, the outer cylinder 14a shown in FIG. 1) and an inner cylinder (for example, the inner cylinder 14b shown in FIG. 1), and the inner cylinder of the lock is pressed by the key. When moved to the locking position, the dial lock may restrict the rotation of the inner cylinder and the outer cylinder may restrict the removal of the key.

With such a configuration, the device can be configured by combining an existing cylinder lock and an existing dial lock, and cost reduction and delivery time can be shortened.

Further, when the inner cylinder of the lock is moved to the unlocking position by the key, the predetermined code of the dial lock may be reset.

With such a configuration, it is possible to prevent the user from forgetting to set the dial lock code, and it is possible to further enhance the crime prevention property of the device.

The configuration of the locking / unlocking device according to the present invention is not limited to the configuration of the locking / unlocking device 10 according to the present embodiment. For example, the inner cylinder 14b of the lock 14 is composed of a disc tumbler type lock, but a pin tumbler type. Other types of locks may be used. Further, although the dial lock 16 is composed of a number matching lock, it may be composed of another type of dial lock such as a character matching lock. Further, although the string-shaped body 18 is composed of wires, other materials may be applied.

The locking / unlocking device according to the present invention can be used as a device for temporarily depositing luggage (carry bag, bag, etc.) at an airport, a station, or the like.
