Patent

CA 2758837

A security device for attachment to an article to deter theft of the article has a housing containing an alarm system including an audible alarm with a defeat mechanism having a two-part connector that attaches to both a cable and a locking mechanism. The connector includes a mechanical fuse (e.g., two-step ferrule holder) that provides defeat prevention of the alarm device. The locked device alarms if pulled too hard from twisting the cable without releasing the primary lock. The connector is preferably shaped as a generally elliptic cylindrical bayonet having an oval transverse cross-section and a truncated oblique cone-shaped distal end. This enables the plug to be inserted into a locking channel of the locking mechanism in either of two directions facilitating the locking of the attached cable about an article of merchandise. Moreover, the oval shape takes up less space than a round bayonet while providing greater strength through longer latch engagement area on the wider side of the bayonet, especially as opposed to a circular cross-section bayonet.

Un dispositif de sécurité à attacher à un objet pour empêcher le vol de lobjet comporte un boîtier contenant un système dalarme comprenant une alarme sonore à mécanisme de mise en échec comportant un connecteur en deux parties qui sattache à la fois à un câble et à un mécanisme de verrouillage. Le connecteur comprend un fusible mécanique (par exemple, porte-virole à deux étages) qui permet la prévention par mise en échec du dispositif dalarme. Le dispositif verrouillé sonne si on tire trop sur le câble en le tordant sans libérer le verrou principal. Le connecteur a de préférence la forme dune baïonnette cylindrique globalement elliptique ayant une section transversale ovale et une extrémité distale conique oblique tronquée. Cela permet à la prise dêtre introduite dans un canal de verrouillage du mécanisme de verrouillage dans lune ou lautre des deux directions facilitant le verrouillage du câble attaché autour dun objet de marchandise. De plus, la forme ovale prend moins de place quune baïonnette ronde tout en offrant une meilleure résistante à travers une plus longue zone de prise de loquet sur le côté plus large de la baïonnette, en particulier par opposition à une baïonnette à section circulaire.
