Optical disc security device having a magnetically actuable locking mechanism
A security device having magnetically actuable locking mechanism for security an optical disc is disclosed. The device includes a detectable security tag secured in a housing having an optical disc receptacle formed as a basin. The housing includes one or more arcuate grooves adjacent to the circular basin. A top cover is sized to fit into the circular basin and is configured to be rotatably mateable with the housing. The top includes arcuate lips extending outwardly therefrom adapted for sliding rotatable engagement with the one or more the arcuate grooves in the housing. Locking the device prevents the top cover from being rotated to a position where the arcuate grooves are fully disengaged with the arcuate lips.
1 . A security device for an optical disc, comprising:
a security tag;
a magnetically actuable locking mechanism operable to lock and unlock the device;
a housing, the security tag and magnetically actuable locking mechanism secured to the housing, the housing having a top surface and an optical disc receptacle formed as a circular basin in the top surface, the housing further including one or more arcuate grooves adjacent the circular basin; and
a top cover sized to fit within the circular basin and configured to be rotatably mateable with the housing, the top cover including one or more arcuate lips adapted for sliding rotatable engagement with the one or more the arcuate grooves, wherein locking the device prevents the top cover from being rotated to a position where the arcuate grooves are fully disengaged with the arcuate lips.
2 . The security device of claim 1 , wherein the magnetically actuable locking mechanism comprises a magnetically actuable latch, a flexible element, and a latch mating element.
3 . The security device of claim 2 , wherein the flexible element and the magnetically actuable latch are combined as a single piece.
4 . The security device of claim 2 , wherein the housing further comprises a channel, and wherein the magnetically actuable latch and flexible element are at least partially disposed in the channel.
5 . The security device of claim 2 , wherein the latch mating element is integral with the housing.
6 . The security device of claim 2 , wherein the latch mating element comprises a recess.
7 . The security device of claim 6 , wherein the recess is contiguous to the channel.
8 . The security device of claim 6 , wherein the recess is configured to allow rotation of the one or more of the arcuate lips through the recess when the device is unlocked, and at least at least a portion of the latch extends into the recess when the device is locked to block rotation of the arcuate lips through the recess.
9 . The security device of claim 6 , wherein the flexible element is positioned adjacent the magnetically actuable latch and biases the magnetically actuable latch toward a locking position in which at least part of the magnetically actuable latch extends into the recess.
10 . The security device of claim 2 , wherein the magnetically actuable latch is positioned between the flexible element and the latch mating element.
11 . The security device of claim 1 , wherein the top cover further comprises a circular top cover base and a cylindrical top cover wall, the top cover wall having one or more guide walls extending radially outward from the top cover wall, the guide walls terminating in the one or more arcuate lips, wherein the one or more arcuate lips are substantially parallel to the top cover wall.
12 . The security device of claim 11 , wherein at least a portion of one of the one or more arcuate lips is positioned within at least a portion of one of the one or more arcuate grooves when the security device is locked.
13 . The security device of claim 2 , wherein the magnetically actuable latch may be moved away from the locking position by magnetic force.
14 . The security device of claim 13 , wherein the magnetically actuable latch may be moved in a substantially linear direction.
15 . The locking mechanism of claim 13 , wherein the magnetically actuable latch may be moved in a substantially rotational direction.
16 . The locking mechanism of claim 13 , wherein the magnetically actuable latch may be moved in a combination of a rotational and linear direction.
17 . The security device of claim 1 , wherein the top cover is rotatable to a position allowing removal of the top cover from the housing when the device is unlocked.
18 . The security device of claim 1 , further comprising a bottom cover secured to the housing.
19 . The security device of claim 18 , further comprising a security tag cover disposed over the security tag, wherein the security tag cover secured to the bottom cover of the housing.
