Patent

CA 2217041

The key comprises a bow (2) equipped with a window (3) through which part (5) of the surface of the cylinder of the key body (4) can be seen. Two grooves running halfway around the circumference of the body (4), and at 180 degrees to each other, end in holes (7). Pins (12) are pressed into the bottoms of the holes (7) by an elastic part (13) in the service position. When more torque is applied to the key bow (2), the pins (12) come out of the holes (7) and the key bow can rotate 180 degrees with respect to its blade (1), thereby allowing the opposite part of the body (4) to be seen through the window (3).

La clé comporte une tête (2) munie d'une fenêtre (3) laissant apparaître une portion (5) de la surface du cylindre du corps (4) de la clé. Deux gorges (6) s'étendant sur la moitié de la circonférence du corps (4) et décalées de 180 degrés sont terminées par des alésages (7). Des goupilles (12) sont pressées au fond des alésages (7) par un organe élastique (13) en position de service. Lorsque le couple appliqué à la tête (2) de la clé augmente, les goupilles (12) sortent des alésages (7) et la tête de la clé peut effectuer une rotation de 180 degrés par rapport à sa tige (1), laissant apparaître de ce fait la portion opposée du corps (4) au travers de la fenêtre (3).
