Description

  The present invention relates to a connector, particularly a connector that connects an article that requires strict storage management, such as a key, and prevents unauthorized removal or loss of the key.

  For example, when a security company receives a fire alarm from a security device installed in a facility that provides machine security, it dispatches a security officer in charge of the area where the facility is located to check the situation. I try to make it.

  For this reason, the security company deposits the key of the facility that performs machine guarding from the customer in advance, and when receiving the warning, the security guard dispatched to the facility possesses the key of the facility, so that the situation of the facility can be confirmed or an abnormal situation can occur The initial correspondence etc. are performed.

   Keys kept from customers are usually stored in a storage box provided in a waiting facility where guards are waiting, and the door of the storage box is locked to prevent unauthorized removal. These keys (which may be one or more depending on the size of the facility, etc.) are usually bundled by a ring for each key of the same machine guard facility, and if the key is stored at the standby facility, the key bundle The key is stored in a key storage box with a hook that secures the ring. Moreover, when a security guard or the like takes out from the storage box and takes it outside, it is carried by hanging a ring in which a key is bundled on an eggplant ring attached to a carrying rope to prevent loss due to misplacement of the key.

  FIG. 10 shows a storage method of these conventional general keys, and shows a state where the keys bundled in the ring are detachably hooked on the hooks of the storage box and stored.

  FIG. 11 shows a state in which the key is hung on the eggplant ring of the carrying rope.

  By the way, the above-described key storage or carrying method has the following problems. In the storage box as shown in FIG. 10, the ring with the key bundled is hooked and fixed on the hook of the storage box, and only the door of the storage box is locked. If this happens, all the keys in the storage box can be removed from the storage box at any time, and unauthorized removal of the keys cannot be prevented.

  Also, in the method of carrying with the above carrying rope, the key ring is structured to be removable from the eggplant ring at any time, so that the key can be removed from the eggplant ring and lost accidents such as misplacement of the key are sufficient. Cannot be prevented.

Therefore, in order to solve the above problem, an interlock type lock box is provided in the bag itself for storing the key, and one key is always inserted into the key insertion opening arranged on the peripheral surface of the lock box and fixed. In addition, the bag cannot be disconnected from the object (bag storage, person's belt, car glove box) connected to this key with a rope, etc., and the bag is stored in the management station. There is proposed a connecting device that limits any one of the following states: a state in a moving vehicle, a state in which the vehicle is moving, or a state in which it is connected to the waist of the person in charge, so that no other state is possible (Patent Document) 1).
JP 2000-110420 A

  However, the above-described connecting device only binds a bag for storing the key, and when the key is taken out of the bag, the key cannot be prevented from being lost due to misplacement or the like.

  Further, the key to be used may be a rod-like one that pushes down the lock pin, and a duplicate of the key or an alternative to it can be easily obtained, so that illegal take-out cannot be reliably prevented.

  The present invention has been made to solve the above-described problems, and ensures that articles requiring strict storage management are always connected to a specific object. For example, a key or the like is a storage or operation rope. It is an object of the present invention to provide a connector that can prevent a key or the like, which is an article to be stored and managed, from being lost or illegally taken out by being fixed to any of the above.

  The above problems are solved by the following means of the present invention.

One feature of the present invention is that
A locking unit for binding articles, a first collation unit group and a second collation unit group corresponding to different keys, respectively, and a key corresponding to the first collation unit group is not inserted in advance. The coupling device is characterized in that a key corresponding to the first verification unit group can be extracted by inserting a key corresponding to the second verification unit group and performing a predetermined operation.

  The present invention is also characterized in that when the key corresponding to the first collating unit group can be extracted, the key corresponding to the second collating unit group is prevented from being removed.

  Further, the connector is bound by one or a plurality of articles and the locking part, and a key corresponding to the first collating part group is fixed to the storage box of the article, and a key corresponding to the second collating part group Is fixed to the carrying means used when the article handler carries the article, and the article is connected to either the storage box or the carrying means.

  According to the present invention, by using a key instead of a lock pin, replication can be made difficult and safety can be further improved.

  Also, by ensuring that articles that require strict storage management are always linked to specific objects, they can be lost or illegally taken out, or keys can be lent to third parties who are not authorized operators. Etc. can be suppressed. For example, in a security company, the key of the security facility where storage management is required can be secured to either the storage or the carrying rope to prevent loss of the key or unauthorized removal. It becomes possible to do.

Embodiments of the present invention will be described below with reference to the drawings.
[Connector structure]
1 and 2 show the basic structure of the connector of the present invention. The connector 10 includes two keys A and B and a socket 1. The socket 1 has a cylindrical shape as a whole, and includes an inner cylinder 3 having key insertion openings 2 open at both end faces, and an outer cylinder 4 outside the inner cylinder 3, and an inner wall of the outer cylinder 4 is in contact with the inner cylinder 3. It has a structure. Further, the socket 1 is provided with a locking portion 7 for locking or bundling articles.

  The outer cylinder 4 and the inner cylinder 3 are supported by a drop-off prevention mechanism 5 shown in FIG. With this drop-off prevention mechanism 5, the inner cylinder 3 can rotate along the inner wall of the outer cylinder 4, but the inner cylinder 3 cannot be taken out of the outer cylinder 4.

  Next, the detailed structure inside the socket 1 will be described with reference to FIGS. 3 (a), 3 (b), 4 and 5. FIG.

  The drop-off prevention mechanism 5 is composed of a ball bearing 5a, a tumbler 5b, and a spring 5c, and is arranged radially at the center of the outer cylinder at an appropriate interval so that the inner cylinder 3 can be stably fixed to the outer cylinder 4. Has been placed. The drop-off prevention mechanism 5 is configured such that the force of the spring 5c causes the ball bearing 5a to be pressed through the tumbler 5b against a recess carved in the inner cylinder, thereby preventing the inner cylinder 3 from falling off the outer cylinder 4 and at the same time It can rotate smoothly along the inner wall of the outer cylinder 4.

  A verification unit 6 is provided in the socket 1. The collating unit 6 is composed of a pin 6a, a tumbler 6b, and a spring 6c, and in the axial direction of the socket 1 as shown in the figure, with respect to each of the two key insertion openings 2 opened at both end faces of the inner cylinder 3. A plurality are arranged and arranged. A plurality of verification units 6 are provided corresponding to the key insertion openings 2 of the keys A and B, respectively. Hereinafter, for convenience, a plurality of collation units 6 provided corresponding to the key insertion slot 2 into which the key A is inserted are collectively provided corresponding to the collation unit group 6A and the key insertion slot 2 into which the key B is inserted. The plurality of verification units 6 are collectively referred to as a verification unit group 6B. The collating unit group 6A and the collating unit group 6B are arranged with a predetermined angle (for example, 90 degrees) shifted so that the position where the key A can be inserted and removed differs from the position where the key B can be inserted and removed.

  Each collating section 6 is pushed out toward the hole (hereinafter referred to as “key hole”) in which the keys A and B of the tumbler 6b and the pin 6a inner cylinder 3 are inserted by the force of the spring 6c. In the state where it is not inserted (left side in FIG. 3A), the tumbler 6b is located at the position of the contact surface between the inner cylinder 3 and the outer cylinder 4, and the inner cylinder 3 cannot rotate.

  When the key A is inserted into the key insertion slot 2 (left side in FIG. 3 (b)), the pins 6a and the tumblers 6b of each collating unit 6 constituting the collating unit group 6A are pressed to the outer cylinder 4 side, and the collating unit group 6A is The boundary surfaces of the pins 6a and tumblers 6b of all the collating portions 6 that are configured coincide with the contact surfaces of the inner cylinder 3 and the outer cylinder 4, so that a shear line is formed. As a result, the inner cylinder 3 can rotate along the inner wall of the outer cylinder 4.

  In FIG. 3, the inner cylinder 3 is in a position where the key A can be inserted and removed, that is, in a position where the pins 6a, the tumblers 6b, and the springs 6c of each verification unit 6 constituting the verification unit group 6A are aligned. The case is described as an example. At this time, the key B inserted into the keyhole is blocked by the pin 6a of each verification unit 6 constituting the verification unit group 6B and cannot be inserted or removed (right side of FIGS. 3A and 3B). This is because the collation unit group 6A and the collation unit group 6B are arranged with a predetermined angle shift.

  Further, the inner cylinder 3 can be rotated by inserting the key A into the inner cylinder 3, but the inner cylinder 3 is rotating (a position that is not one of the positions where the key A or the key B can be inserted and removed, that is, When the pin 6a, the tumbler 6b, and the spring 6c of each collating unit 6 constituting the collating unit group 6A and the collating unit group 6B are not in a straight line position), the pins 6a of the collating unit 6 Extraction is blocked and no key can be removed (FIG. 4).

  When the inner cylinder 3 is rotated to a position where the pins 6a, the tumblers 6b, and the springs 6c of the collating units 6 constituting the collating unit group 6B are aligned, the pins 6a of the collating units 6 constituting the collating unit group 6B Push-up is possible and the key B can be removed.

  When the key B is extracted, each collating unit 6 constituting the collating unit group 6B is pushed out by the force of the spring 6c so that the tumbler 6b and the pin 6a are pushed toward the key hole of the inner cylinder 3 (right side in FIG. 5). As a result, the tumbler 6b is positioned at the position of the contact surface between the inner cylinder 3 and the outer cylinder 4, and a shear line cannot be formed, so that the inner cylinder 3 cannot rotate. Further, the key A inserted into the keyhole is prevented from being pulled out by the pin 6a of each collating unit 6 constituting the collating unit group 6B, and cannot be pulled out from the inner cylinder 3 (left side in FIG. 5). In order to remove the key A, first, the key B is inserted into the inner cylinder 3 again, so that the inner cylinder 3 can be rotated. Then, if the inner cylinder 3 is rotated to a position where the key A can be inserted / removed, that is, a position where the pins 6a, tumblers 6b, and springs 6c of the collating units 6 constituting the collating unit group 6A are aligned. A can be extracted.

[Operation of connecting tool]
Next, the operation of the connector of the present invention will be described by taking as an example the case of managing the taking out of a key bundle.

Storage of Key in Storage Box FIG. 6 is a view showing a state where the key bundle 20 is housed and fixed in the storage box 30 by the connector 10.
One or more keys A are fixedly installed in the storage box 30.

  The connector 10 to which the key bundle 20 is bound has two connecting portions A and B each provided with a collation portion group, and different keys (key A and key B) correspond to each other.

  When the key bundle 20 is stored in the storage box 30, the key 10 provided in the storage box 30 is inserted into one connection portion A of the connection tool 10 so as not to be removed, so that the connection tool 10 is moved to the storage box 30. The key bundle can be fixed and stored in the storage box 30.

A case where an operator such as a security guard who takes out a key from the storage box removes the connecting tool 10 with the key bundle 20 connected to the storage box 30 and takes out the key bundle 20 will be described with reference to FIG. When the operator takes out the key bundle 20 and carries it, he / she connects the connecting tool 10 with the key bundle to the carrying rope 40 which is a carrying means and wears it. This carrying rope 40 is bound to the belt of the operator.

A key B is fixed to the carrying rope 40 worn by the handler of the key bundle 20. When the operator takes out the key bundle 20 from the storage box 30, the operator first fixes the carrying rope 40 to the connecting portion B of the connector 10 as shown in FIGS. 7 (a) and 7 (b). Insert key B. Then, as described above, since the inner cylinder 3 of the connecting portion 10 can be rotated, by rotating the inner cylinder 3 of the connecting portion 10 to a predetermined position (FIG. 7C), the connecting portion 11 is It can be extracted from the key A (FIG. 7D). Thereby, the coupler 10 (key bundle 20) can be taken out from the storage box 30.
As described above, the connector 10 (key bundle 20) taken out cannot be removed from the key B fixed to the carrying rope 40.
As described above, by using the connector 10 according to the present invention, it is possible to prevent the key bundle from being illegally taken out and to ensure the storage management of the key bundle.

Carrying the Key Bundle As shown in FIG. 8, the connector 10 (key bundle 20) extracted from the key A cannot be removed from the key B when extracted from the key A in the storage box 30 as described above. (FIG. 8). For this reason, the operator can carry the connector 10 (key bundle 20) taken out from the storage box 30 only in a state where it is connected to the carrying rope 40 bound to the belt of the operator. The key ring 20 can be constantly kept in a state worn by the operator.

  As described above, by using the connector 10 according to the present invention, it is possible to prevent the misplacement of the key bundle of the handler or the lending of the key to a third party who is not a regular handler. It can be certain.

Management of Key Bundle Operator Next, management of authority of the handler such as taking out the key bundle stored in the storage box will be described.

  In FIG. 9, one or more keys A are stored in the storage box 30, and the same key A as the key A fixed to the storage box 30 is stored in the carrying rope A of the handler A, and the carrying rope B of the handler B. The key B and the key C are fixed to the carrying rope C of the operator C, and the keys A, B, and C are different from each other.

  When the connector 10 (key bundle 20) is stored in the storage box 30, the key A of the storage box 30 is inserted into the connecting portion A including the verification tool group corresponding to the key A, and stored. When the connector 10 (key bundle 20) is taken out from the box 30, the connector 10 (key bundle 20) can be taken out only by the key B corresponding to the other connector B.

  That is, only the operator B carrying the key B can take out the connector 10 (key bundle 20) from the storage box 30, and the operator A and the operator C remove the connector 10 (key bundle 20). It cannot be taken out.

  When the connecting tool 10 (key bundle 20) is connected to the carrying rope B of the operator B, the key B possessed by the operator B is inserted into the connecting portion B having a matching tool group corresponding to the key B. The connection with the carrying rope B of the operator B can be released by the key A corresponding to the other connecting portion A.

  A key A (the same key as the key A fixed to the storage box 30) is fixed to the carrying rope of the handler A. Therefore, the handler A cannot take the connector 10 (key bundle 20) directly from the storage box 30. However, by inserting the key A held by the operator B into the connecting portion A of the connector 10 that is taken out by the operator B and connected to the carrying rope B of the operator B, the connector 10 (key bundle 20) and The connection with the carrying rope B of the operator B is released, the connecting tool 10 (key bundle 20) is connected to the own carrying rope A, and the key bundle 20 can be carried.

  However, when the connection tool 10 (key bundle 20) is connected to the carrying rope A of the operator A, the connection portion A corresponding to the key A is handled as in the case of being stored in the storage box 30. The key A possessed by the operator A is inserted, and the connection with the carrying rope A of the operator A can be released only by the key B corresponding to the connecting portion B. Therefore, the operator A cannot directly return the connector 10 (key bundle 20) to the storage box 30, and taking out and returning the connector 10 (key bundle 20) from the storage box 30 is authorized. It is performed only by the person B.

  In addition, since the key C fixed to the rope C for carrying of the operator C does not correspond to any of the connection parts A and B of the connector 10, the operator C stores the connector 10 (key bundle 20) in a storage box. It is not possible to carry out from 30 or carry the connector 10 (key bundle 20).

  As described above, by using the connector 10 of the present invention, the authority to take out the connector 10 (key bundle 20) from the storage box can be given only to a specific person, by an unauthorized person. It is possible to reliably prevent unauthorized removal of a key ring or lending of a key to a third party who is not an authorized person.

  When a plurality of key bundles 20 with different handlers are stored and managed in the same storage box 30, the connection part B of the coupler 10 described so far is different for each key bundle or each key bundle handler. An operator who is allowed to take out each key bundle 20 only receives a key corresponding to the connecting portion of the connector 10 (key bundle 20) that the operator is allowed to take out from the storage box 30. Possess.

  Thus, even when a plurality of key bundles with different handlers are stored and managed in the same storage box, unauthorized removal of the key bundle by a third party who is not an authorized handler can be reliably prevented.

  As described above, according to the present invention, since the key bundle is always fixed to either the storage or the operation rope, it is possible to suppress the loss or unauthorized handling of the key bundle.

  Further, according to the present invention, using a key instead of a lock pin makes it difficult to duplicate and further enhances safety.

  Although the present invention has been described with respect to the case of managing a key ring, it is clear that the connector is not limited to the management and storage of the key ring, but can be applied if strict management storage is required. is there. For example, it can be used for various purposes, such as storage management of company seals, real seals, and storage management of ID cards.

It is a figure which shows the basic structure of the coupling tool of this invention. It is a figure which shows a drop-off prevention mechanism. It is a figure which shows the state from which the key A was extracted and the key B cannot be extracted from an inner cylinder. It is a figure which shows the state which cannot remove any of the keys A and B.
