Description

  The present invention relates to a key device of a safe deposit box.

  Conventionally, a safe deposit box has been installed in a bank, a credit union, a securities company, etc., and is generally used for storing important documents, seals, precious metals, and the like. In general, a safe deposit box installed in a bank or the like is arranged in a number of rows and columns in a safe deposit box with limited entrances and exits. Banks, etc., who are the managers providing such safe deposit boxes need to make every effort to ensure security and reliability. On the other hand, from the customer's point of view, the procedures are simpler and more simplified. It is preferable that a safe can be used in operation.

  The safe deposit box installed in the bank, etc., one generation ago is a manual type with two locks that the manager on the manager side guides the user to the safe deposit box and unlocks the safe deposit box in the presence of them. there were. For example, in a bank, when a customer submits an opening request form in which a customer has filled out and stamped predetermined items to the bank, the bank will guide the customer to the safe deposit box after confirming the identity by checking the seal. It is. The safe deposit box is provided with two sets of locks, a user lock that is managed and unlocked by the user, and an administrator lock that is managed and unlocked by the administrator. The administrator opens the safe door simultaneously with the presence of both the administrator and the user. When the use is over, the safe is locked with the keys of both parties again.

However, in recent years, from the viewpoint of protecting the privacy of individuals in accordance with the advancement of security systems, and from the viewpoint of labor saving for the administrator side, only users can unlock / Semi-automatic safe deposit boxes that lock are used.
The semi-automatic safe deposit box is to keep the administrator lock out of the administrator lock and the user lock at all times, and to lock the key device by shielding the lock hole of the administrator lock and the user lock with the key device. It will be blocked by. When unlocking, an authentication key for a writable / erasable key device is prepared, the registration number is written by receiving this authentication key from the administrator side, and the key device is opened by inserting the authentication key into the key device. In order to lock and move, the lock hole of the user lock is exposed and the safe deposit box is unlocked with the key owned by the user. When the use is completed, the safe deposit box is locked, and the key device is returned to its original position to shield the lock hole, thereby closing the lock hole and locking it twice. The authentication key is returned to the administrator side, and the administrator side erases the contents written in the authentication key to prepare for the next use.

  This semi-automatic safe deposit box has the advantage that it can be realized by remodeling an existing manual safe deposit box that uses an administrator lock and a user lock without bothering the user and taking care of the administrator. . Various techniques relating to a key device used in such a semi-automatic safe deposit box are known (see, for example, Patent Document 1).

  For example, when a key device is attached to a safety deposit box door, it is necessary to have a dimension that shields the user lock and the administrator lock and an unlock mechanism that unlocks and locks the key apparatus itself. There was a problem of becoming horizontally long. Furthermore, the downsizing of the authentication key was limited from the viewpoint of the performance and ease of handling of the authentication card. Therefore, in Patent Document 1, the unlocking mechanism portion is arranged on the front face of the safe deposit box and is structured to be removable at the time of unlocking, so that the conventional card type authentication key is used as it is and the width dimension is small. A technique related to a key device that can be attached to a safety deposit box door is disclosed.

  By the way, since the key device used for the safe deposit box is installed for the purpose of hiding the lock hole of the safe deposit box door, it is provided so as to protrude from the surface of the safe deposit box door as described above. Furthermore, since a safe deposit box is required for each of a plurality of users, it is provided on the entire wall of a safe deposit box. In other words, in the safe deposit box, a large number of safe deposit boxes of the same shape are often installed adjacent to each other. Therefore, an identification character is attached to the surface of the key device so that a safe deposit box for each user can be clearly identified.

  However, since the identification characters attached to the key device are displayed toward the front, just by entering the safe deposit box, a large number of safe deposit boxes can be viewed from the side regularly. In many cases, it is difficult to find the target safe deposit box, and there is a problem that it takes time to reconfirm the identification character of the key device from the front face to face the safe deposit box.

  The present invention has been made to solve the above problems, and provides a key device that can improve the visibility of an identification character displayed on the key device.

In order to solve the above problems, the present invention proposes the following means.

  According to such a configuration, since the display portion on which the identification character is displayed is a curved surface having a convex shape in front of the key device, the key device is viewed from the left and right directions other than the front surface. The area where the identification character can be visually recognized is enlarged, and the visibility can be improved.

According to such a configuration, the exterior surface, which is the outer surface of the front surface portion of the key device, is a curved surface that has a convex shape toward the front from both ends in the direction orthogonal to the rotation axis. When the safe deposit box door is opened, a portion that comes into contact with the key device installed in the adjacent safe deposit box door becomes a curved surface. Therefore, a corner | angular part does not contact with an adjacent key apparatus and a damage can be prevented effectively.
In addition, since at least a part of the curved exterior surface constitutes the display unit, it has an appearance constituted by a curved line, so that the design of the key device can be improved.

  Furthermore, the key device according to another aspect of the present invention is characterized in that the display unit further includes a buffer member that has a convex shape toward the front of the safety deposit box door.

  According to such a structure, it has the buffer member which makes convex shape ahead, and an adjacent key apparatus and a buffer member will contact first. Thereby, damage can be prevented more effectively.

  According to the key device of the present invention, the visibility of the identification character displayed on the key device can be improved by making the display unit a curved surface having a convex shape forward.

This makes it possible to effectively prevent the exterior surface 211a and the display portion 212 on the exterior surface 211a from being damaged by contacting the corners and surfaces.

  Furthermore, in order to prevent scratches, the identification characters are not damaged and the visibility is not impaired. In addition, when the safety deposit box door 10 is opened, even if it is in contact with the user himself / herself or other personal belongings other than the key device 2 of the adjacent safe deposit box 1, the contact is often made on a curved surface. It is possible to prevent the contact partner from being severely damaged.

  Further, by forming the forwardly protruding display portion 212 with the buffer member 212a, the portion of the key device 2 that protrudes most forward is the buffer member 212a, and the adjacent key device 2 and the user and the buffer member 212a. Will be contacted first. As a result, it is possible to more effectively prevent a contact partner such as the adjacent key device 2 or a user from being damaged.

  In addition, the display unit is arranged on the exterior surface 211a formed by a curved surface having a convex shape toward the front of the safety deposit box door 10 toward the center from both ends in the horizontal direction, which is a direction along the surface of the safety deposit box door 10. As a result, it has a streamlined appearance composed of curves, and the design can be improved.

It connects with the apparatus main body 20 so that it may carry out. Thereby, the power storage unit 232 does not protrude from the front surface of the key main body 231. Therefore, in a state in which the authentication key 23 is inserted into the casing unit 21, the power storage unit 232 does not protrude to the front of the casing unit 21, and the key device 2 becomes thick by inserting the authentication key 23. Can be prevented.

  Further, as shown in FIGS. 8B and 8C, the power storage unit 232 is connected to the apparatus main body 20 so that the convex shape from the key main body 231 protrudes toward the safe deposit door 10 side. Thus, when the authentication key 23 is inserted from the key body 231 into the key insertion part 213, the power storage part 232 reduces the step between the safe deposit door 10 and the key insertion part 213. Accordingly, the authentication key 23 can be inserted in parallel to the insertion hole 213b without being greatly inclined when the authentication key 23 is inserted. Therefore, the authentication key 23 can be easily inserted into the key insertion unit 213.

Further, when the authentication key 23 is inserted into the key insertion portion 213, the edge portion 233 is formed so as to be in contact with the surface of the safety deposit box door 10, and is inserted while being pressed by the surface of the safety deposit box door 10. As a result, the step between the safety deposit box door 10 and the key insertion portion 213 can be absorbed by the edge portion 233, and is not tilted when the authentication key 23 is inserted, and is inserted parallel to the insertion hole 213b. be able to. Therefore, it becomes possible to insert the authentication key 23 into the key insertion unit 213 more easily.
Further, the edge 233 is formed so as to contact the safe deposit door 10 when the authentication key 23 is inserted. Accordingly, the edge 233 can be formed regardless of the shape and size of the key body 231 and the power storage unit 232.

Furthermore, an arrow shape pointing to both ends in the horizontal direction is formed on the side surface portion on the upper side, and the direction indicated by the arrow shape matches the moving direction of the key device 2 from the locked position to the open position. Thereby, the apparatus main body 20 can be moved while confirming the unlocking / locking direction by the arrow shape. That is, the unlocking / locking method of the key device 2 can be visually recognized, and even when it is used for the first time, it can be easily used without being confused by the unlocking / locking method.
Further, since the arrow is formed in a concave shape, it is difficult to slip when the apparatus main body 20 is moved from the locked position to the open position, and therefore, it can be used more easily.
