Locking device for CD / DVD case displaying box}

The present invention relates to a lock device for a CD / DVD case display box, and protrudes for pressurizing it by processing at least two or more steps of locking grooves on a locking pin for pressing and holding a CD or DVD stored in the anti-theft case. The present invention relates to a shelf lock that can be used to store CDs or DVDs of a slightly different size in a single shelf by varying the fixed length.

In general, a CD / DVD case is a plastic flat plate case designed to protect a CD / DVD that is not durable at all, especially in the case of a coated surface. The main body is configured to be hingedly connected to one corner of the main body, and a cover mounted to open and close in a snap manner. Such CD / DVD cases are also usually sold wrapped in a thin vinyl cover surrounded by an outer surface or wrapped in a cover such as a paper box.

Therefore, when the product is displayed in a CD / DVD store for sale, the plastic package is unopened, and when it is displayed on the rental site for rental purposes, the plastic package is opened and stored in the showcase. Choose from CD / DVD and pay rent at checkout.

However, in the process of renting or purchasing, consumers who have been using the small size of the CD / DVD case for unauthorized fraud began to appear, and the necessity to block such fraudulent acts began to emerge. Prevention devices have been proposed. As one of them, the applicant has proposed a 'display case' of Patent Registration No. 196459, filed on June 15, 1996 and registered on February 20, 1999.

According to the display case, that is, the display according to the present invention, the anti-theft circuit is installed on the wall of the enclosure, and the anti-theft alarm device is installed near the entrance of the shop. If passed, theft alarm is activated to prevent theft.

Therefore, as shown in FIG. 1, the display box has a rectangular opening in which an opening 103 into which a CD / DVD case is inserted is cut in one side, and a storage space 102 for accommodating the case is formed therein. It takes the form of an enclosure, and the edge portion of the opening 103 serves as a locking jaw 104 to prevent the CD / DVD case from being separated, and the holding hole for holding the display box 100 on the opposite surface of the opening 103. The mounting hole 107 for installing the 105 and the anti-theft circuit board is cut out. In addition, at the bottom of the display box 100, as shown in the bottom of FIG. 1 and FIG. 2, a locking device 109 for locking and unlocking the CD / DVD case 110 accommodated in the storage space 102 is provided. It is installed.

As shown in FIG. 2, the locking device 109 moves vertically in the storage space 102 of the display box 100 to contact or be spaced from the bottom of the CD / DVD case 110. Locking pin 111 to lock or unlock the inside of the display box 100, the locking piece 117 and the locking pin detachable to the locking groove 115 cut around the guide shaft 113 of the locking pin 111 It consists of a cap body 119 attached to one side of the bottom surface of the display box 100 to surround the 111 and the locking piece 117.

Therefore, in order to safely display and display the CD / DVD case 110 by the conventional display box 100 to which the locking device 109 having the above configuration is attached, as shown in FIG. In the state in which the head 121 is in close contact with the bottom surface of the display box 100, the CD / DVD case 110 is accommodated in the storage space 102 through the opening 103. At this time, since the locking pin 111 is lowered as far as possible, the storage space 102 is secured to allow the storage 110 to receive the case 110 through the opening 103.

Then, when the lower protrusion of the guide shaft 113 is pressed, the locking pin 111 is pushed up while pushing the CD / DVD case 110 up by the head 121, and then the locking piece 115 is inserted into the locking groove 115. 117 is fixed while being elastically fitted, the locking pin 111 is pushed up the case 110, thereby eliminating the upper and lower free space in the storage space 102, together with the locking step 104 The case 110 is fixed in a locked state.

On the contrary, when the CD / DVD case 110 is to be removed from the display box 100 for sale or rental, the release block 130 shown in FIG. 2 is used, and the case 110 is displayed in a locked state. When the box 100 is inserted into the release hole 131 of the release block 130 as shown in FIG. 2, the metallic locking piece 117 is formed by the magnetic force of the permanent magnet 133 embedded in the left and right sides of the release hole 131. This will happen from side to side. At the same time, the locking pin 111 released from the locking piece 117 falls down by the weight and the weight of the case 110 and returns to the state shown in FIG. 2, whereby a free space is secured again. The CD / DVD case 110 can be easily taken out in the 102.

By the way, the lock device 109 applied to the conventional CD / DVD case display box 100 to lock and release the CD / DVD case 110 as described above is fitted to each other to lock the locking pin 111 to lock Since the locking groove 115 and the locking piece 117 are provided with only one coupling position, the length of the locking pin 111 protruding into the storage space 102 of the display box 100 is always at the time of locking. It becomes constant.

Therefore, if the case of CD or DVD is enlarged or the size of the case is reduced due to the compactness of the internal structure by enclosing the printed material inside these days, the protruding length of the locking pin 111 is constant as described above, and the standard dimensions are By the display box 100 manufactured on the basis of the case 110, there was a problem that can not normally be stored in the new case is slightly changed in size as described above.

In other words, when storing the CD / DVD case 110 which is smaller in size, even if the locking pin 111 is pressed up, the free space remains inside the storage space 102, so that the case comes out through the opening 103. On the contrary, when the size of the case is large, the locking pin 111 cannot be pressed to the locked position, that is, the locking groove 115 and the locking piece 117 are not fitted with each other, thereby preventing the locking itself. There was a problem that it could not cope with the change in the size of (110) at all.

The present invention has been proposed to solve the problems of the conventional CD / DVD case display box locking device as described above, two or more stages on the outer peripheral surface of the guide shaft of the lock pin to keep the CD / DVD case in the display lock state By processing the locking groove to form the locking position where the locking piece is caught and fixed, two or more stages are formed so that the length of the locking pin protruding into the display box within the uniform display box can be changed to display various sizes of CD or DVD cases. The purpose is to make it available for storage.
