Patent

CA 2229963

A security indicator has a two part telescopic locking bar attached to the handle of a door at one end and to the door or door jamb at the other end through an end piece. The device includes a cup or tube which encases the door handle, preventing use of the handle. The length of the bar is fixed by aligning apertures in each part of the telescopic locking bar to form a continuous aperture, inserting a frangible pin through the continuous aperture and locking the frangible pin in place with a padlock received by a hole in the frangible pin. The pin has a narrow portion which can be broken by relatively little human force. The device requires someone who does not have the key to the padlock on the frangible pin to break the frangible pin to enter a door fixed with the device. A broken pin alerts the occupant that an entry has occurred during his/her absence. A sleeve normally protects the narrow portion but slides easily away to expose the narrow portion when entry is desired.

Cette invention concerne un indicateur d'effraction monté sur une barre télescopique deux pièces interdisant la manoeuvre d'une poignée de porte. La barre télescopique porte à bout un tube ou une coquille où se loge la poignée dont on veut interdire la manoeuvre, l'autre bout de la barre étant fixé à la porte même ou au cadre de porte. La longueur de la barre se règle en alignant des trous ménagés dans chacune des deux pièces formant la barre et en mettant en place une goupille frangible qui sera verrouillée en place au moyen d'un cadenas. La goupille comporte une partie amincie que l'on peut briser avec relativement peu d'effort. Pour entrer par une porte protégée par une telle barre télescopique sans avoir la clé du cadenas, il faut briser la goupille. Une goupille brisée signale à l'occupant autorisé de la pièce ou du logement que quelqu'un est entré pendant son absence. La partie amincie de la goupille est normalement protégée par un manchon que quiconque veut entrer peut repousser aisément.
