Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a security lock device to be mounted on a case for storing a recording medium such as a compact disk on which music and images are recorded.

[0002]

2. Description of the Related Art A compact disc (CD) on which music and video are recorded, a digital versatile disc (DV)
Disc-shaped recording media such as D) are sold in a state housed in a case with a door. Hereinafter, in this specification, the “recording medium” refers to a disc-shaped recording medium such as a CD or a DVD. At the rental shop, when the recording medium was taken out of the sales case and stored in a storage shelf in the counter, empty sales cases were arranged on the shelf for display, and when the recording medium was lent out, for example, "rented" was written. It is common practice to attach a bill to a sales case with a rubber band and display it again. Furthermore, in the rental shop, in order to prevent unauthorized removal of the recording medium, the security case equipped with a lock displays the sales case containing the recording medium in a storage case. However, a security system that detects a detection element attached to a security case at the exit of a shop and sounds an alarm buzzer is adopted. As an example of such a security case, Japanese Unexamined Patent Publication No. 9-290856 discloses a lock body provided with a keyhole at a side of a case body having an insertion opening at a front end face for inserting and removing a sales case containing a recording medium. A structure is disclosed in which the latch is locked to the case body when the lock body is pushed in, and the lock piece is projected from the insertion opening so that the internal sales case cannot be taken out.

[0003]

When a recording medium is taken out of a sales case that has been shipped from a conventional manufacturing and sales company and an empty case is presented for display, the recording medium is illegally taken out. Can be avoided. However, the case is not retrofitted with a security lock device and displayed. Further, in the case of the latter security case, since the lock can be easily opened by intentionally inserting a nail or the like into the keyhole, there is a concern that the internal recording medium may be illegally taken out. If not, a large number of security cases must be purchased at the rental shop, resulting in a disadvantage that the cost is extremely high.

An object of the present invention is to provide a security lock excellent in convenience which can be integrally molded with a synthetic resin with a simple structure and can be easily retrofitted to a conventional sales case for storing a recording medium. is there.

[0005]

According to the first aspect of the present invention, there is provided a rectangular case body for accommodating a recording medium such as a compact disk, wherein a support pin and a printed material are supported on inner surfaces of both side pieces. And a door having a substantially U-shaped cross section and a free end open at the free end side is provided on the support pin so that the door can be freely opened and closed by an external force applied in a closed state. A security lock which is freely detachably provided in a case for storing a recording medium provided with a play state in which the side is slightly opened and an external force is removed to return to a completely closed state. The lock has a resilient lock piece having a locking claw protruding from an outer portion, an elastically deformable stopper piece having an abutting portion formed so as to face an inner portion of the lock piece, and a width direction. Leave a predetermined space on the edge A lock body provided with a protruding piece formed in an opposed shape at one end side, and a gap for loosely fitting the free end side of the door between the one protruding piece and the lock piece; and And a key provided to retreat the lock piece with a pin inserted from the other end of the lock body to release the engagement of the locking claw, and to close an open portion on the free end side of the door. The lock piece of the lock body is inserted from the gap between the projecting wall portion of the case body formed as described above and the slightly opened inner surface of the door, and the engaging portion between the projecting pieces is formed on the outer surface of the case body and the door. By inserting and attaching the lock body to the case, the locking claw of the lock piece is locked in the hole formed in the side piece of the door, and the closed state of the door is maintained. Features.

According to a second aspect of the present invention, there is provided a security lock mounted on a case for storing a recording medium according to the first aspect, wherein the reinforcing plate is formed integrally with the lock body. Alternatively, information relating to rental is displayed on the front surface or the back surface of the protruding piece.

According to a third aspect of the present invention, there is provided a security lock to be mounted on a case for accommodating a recording medium according to the first or second aspect, wherein a security detection piece is provided on the lock body. It is characterized in that a space for attaching is provided.

[0008]

In order to attach the lock body to the case for storing the recording medium, the lock body is locked through the gap between the projecting wall of the case body and the slightly open inner surface of the door. This is performed by inserting a piece and inserting the engaging portion between the projecting pieces into the outer surfaces of the case body and the door. As a result, the locking claw of the lock piece engages with the hole of the side piece of the door, and the door is held in a closed state. In this state, if the locking claw is intentionally pushed from the outside and the lock body is to be removed, the engagement of the locking claw should be released because the locking piece hits the contact portion of the stopper piece to prevent retreat movement. Can not.

When the lock pin is retracted by inserting the key pin from the other end of the lock body, the locking claw that has entered the hole is disengaged, and the door can be opened.

(Invention of claim 2) In the rental shop, desired information on rental such as "Rental OK" is displayed on the front or back surface of the reinforcing plate or the protruding piece of the lock body, and the case is presented for display. It is convenient.

(3) Since a space for attaching the security detection piece to the lock body is provided on the lock body, the case is not damaged as compared with the case where the security detection piece is directly attached to the case. Easy to rent and second-hand goods.

The security lock to be mounted on the case for storing the recording medium can be manufactured at a low cost because it can be integrally molded with a synthetic resin with a simple configuration, and the locking and unlocking operations can be easily performed. In addition, the security case can be used as a display case with a security function for the purpose of renting or selling used goods by retrofitting the security lock using the sales case of the recording medium conventionally distributed as it is. .
