Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a storage safety device for a stored object.

[0002]

2. Description of the Related Art In recent years, the market has been flooded with compact discs, cassette tapes (audio and video tapes), etc., and the number of dealers has increased, so that customers can easily and comfortably choose a disc to purchase. Also, the disc can be freely accessed. On the other hand, the size of the discs has become smaller as compact discs have been introduced to the market, and theft of compact discs has become a more important issue for retailers. Therefore, in order to effectively prevent theft, a method is provided in which a box for storing a compact disc or a cassette tape is provided with a sensor for activating an electric alarm system to prevent the disc from being taken out. However, in this method, the disc may be taken out of the box and held only by the disc, while the empty box may be left on the shelf and passed through the alarm system. Therefore, it is necessary to install some safety device to make it difficult for the customer to remove the disc from the box and combine it with the sensor described above. Moreover, as a safety device, it is inexpensive, difficult for customers to open, easy to handle by the sales staff, there is no adverse effect on other products due to its use, and above all it is accepted by the shop owner. There is a demand for a storage safety device such as a cassette that can be used.

Therefore, several different storage safety devices have been developed. As a storage safety device for a general cassette, the structure of the storage safety device disclosed in JP-A-4-502442 has a lock member for engaging and locking the cassette on the outside surrounding the cassette. A safety device provided with a magnetically actuable latching means,
The lock member includes a rotary bolt housed in the lock housing, and the rotary bolt is adjusted from the outside of the lock housing to the engaging position and the releasing position. When locked, it breaks the cellophane that wraps the cassette with the claws of the rotating bolt, reducing the product value, and when unlocked, it uses a strong magnet, which adversely affects other products handled by the store. There was an unfavorable problem for the store, such as causing a problem.

In order to solve the above problems, the applicant of the present application previously applied for a storage safety device for an object to be stored in Japanese Patent Application No. 6-231444. The outline will be described with reference to FIG.

First, FIG. 15 shows C from the top of the hard case.
It is a perspective view which shows the state which inserts a D case. In FIG. 15, reference numeral 1 is a CD case, and 2 is a hard case for accommodating the CD case 1, both of which are injection-molded products made of a plastic material such as polycarbonate. The hard case 2 has a parallelepiped shape having two pairs of side frames 20, 21 and 22, 23, and an upper surface and a lower surface frame. A CD case insertion / removal opening 27 is formed on the upper surface, and the inner shape thereof is the CD shape. The case 1 is configured to be movable. The upper surface frame and the lower surface frame of the hard case 2 are formed across the end portions of the pair of side surface frames 22 and 23.
The CD, which is composed of upper surface prevention walls 24 and 25 and lower surface prevention walls 26, and is surrounded by the two upper surface prevention walls 24 and 25.
The planar shape of the case insertion / removal opening 27 is smaller than the planar shape of the CD case 1.

The lock mechanism 3 comprises a lock housing 30 and a lock key 40.

1 has a gap bar 42 having a U-shaped cross section, one side frame 22 of the hard case 2 has a gap bar insertion port 28, and a side frame adjacent to the gap bar insertion port 28. The lock housing 30 is attached to 20.

With the above construction, as shown in FIG. 15, the operation is performed by placing the CD case 1 on the upper surface of the hard case 2 in the completely released state with the lock key 40 pulled out.
After being inserted obliquely from the D case insertion / removal opening 27 and dropped in, it is brought closer to the side frame 21 side on the opposite side to which the lock mechanism 3 is mounted. Since the inner shape of the hard case 2 is configured such that the CD case 1 can move, a certain gap can be created between the side surface of the CD case 1 and the side frame 20.

In the above state, when the lock key 40 is pushed in until it stops, the clearance bar 42 enters the clearance and presses the side surface of the CD case 1 with the clearance bar pressing surface, and the lock key body 41 locks the lock housing 30. Slide in and lock the 4 key hooks into the lock housing 3.
It is locked in the locking recess 32 of No. 1 with good moderation. Said C
The D case 1 is blocked by the upper surface prevention walls 24 and 25 and the lower surface prevention wall 26, so that the hard case 2 cannot be taken out.

To release the lock, the outsides of the four key hook portions are simultaneously pushed inward against the spring property of the lock key main body 41 by a releasing jig to be removed from the lock recesses 32, and then the gap bar 42 is removed. The unlocking is completed by pulling out. Therefore, the hard case 2 and C
Since there is backlash between the D case 1 and the case,
The CD case 1 is moved to the outside of the hard case 2 while tilting the CD case 1 by pushing the CD case 1 toward the side surface frame 20 side and pushing the CD case 1 from the side of the lower surface prevention wall 26 by an operation reverse to the insertion of the CD case 1. You can take it out.
