Removable security device for portable articles
First Claim
1. A removable security device for portable articles comprising(a) an alarm housing including an audible alarm circuit, a locking mechanism, and a bottom surface;
- (b) a receiver adapted to be attached to said portable article;
(c) a pair of opposed rails on said alarm housing bottom surface, said rails defining a channel approximately parallel to said bottom surface and having an ingress;
(d) a pair of opposed flanges on said receiver shaped to mate relatively snugly with said channel and to slide into said channel ingress;
(e) a stop means for preventing said flanges from sliding beyond effective engagement with said channel, said alarm housing being installed on said receiver when said flanges are slid into said channel and stopped by said stop means; and
(f) a lock bolt selectively operated by said locking mechanism to extend from said alarm housing bottom surface into a shaped depression in said receiver when said alarm housing is installed on said receiver to secure said alarm housing to said receiver, and to retract from said shaped depression into said alarm housing bottom surface to permit removal of said alarm housing from said receiver.

Abstract
A removable security device for a portable article that includes an alarm housing with an audible electronic alarm circuit and a locking mechanism, a receiver that attaches to the portable article. The alarm housing has a pair of opposed rails that define a channel and the receiver has a pair of opposed flanges that mate with and that slide into the channel. A lock bolt, operated by the locking mechanism, extends from the alarm housing into a shaped depression in the receiver to secure the alarm housing to the receiver, and retracts from the depression to permit removal of the alarm housing from the receiver. The audible alarm is triggered by a motion detector or by cutting an attached cable.

10. A removable security device for portable articles comprising
(a) a alarm housing including an audible electronic alarm circuit, a locking mechanism, a retractable cable having a free end with a plug shaped to mate with a socket in said alarm housing, and a bottom surface; -
(b) a receiver adapted to be attached to said portable article;
(c) a pair of opposed linear sets of L-shaped protrusions on said alarm housing bottom surface, said L-shaped protrusions defining a channel approximately parallel to said bottom surface and having an ingress;
(d) a pair of opposed flanges on said receiver shaped to mate relatively snugly with said channel and to slide into said channel ingress;
