Diebstahlsicherung für ein Fahrzeug

摘要

An anti-theft device (1) intended for vehicles belongs to a type, which is capable of retaining the vehicle brake in a braking condition, as long as it is activated, and which is non-interfering with the brake in an inactivated condition. The anti-theft device (1) comprises a lock rod (3) provided at one end with hook or crook (5) for gripping around a brake pedal arm (26), the lock rod (3) to a major extent consisting of a shank portion (4), which is releasably lockable within a lock housing (2), which in turn is firmly secured to the vehicle in the vicinity of the brake pedal. The shank portion (4), which is provided with a helicoidal groove (6), extends through the lock housing and through a rotatably disposed element (14) therein, the hole for the shank portion (4) through the rotatable element (14) having a helicoidal ridge (16), which is complementary to the helicoidal groove (6) in the shank portion (4) and cooperates therewith. Displacement of the lock rod (3) thus results in rotation of the rotatable element (14). A latch (18) is biased into engagement with the rotatable element (14) in order to permit the rotation of the rotatable element (14) in only one of its two rotational directions. A solenoid (22) is provided to move the latch (18) out of engagement with the rotatable element (14) when energized and thereby permit the free rotation of the rotatable element (14) in both of the two directions.
