Abstract: An antitheft device for attachment to a steering wheel of an automobile comprising an elongated body member having two parallel passageways extending in a longitudinal direction. A first hook is secured to the body member for engagement with a portion of the steering wheel. The first hook engages the wheel from the inside of the rim, with the body member extending outward beyond the periphery of the steering wheel, an elongated rod member, adapted to move in telescopic fashion in one of two passageways formed in the body member, and extending longitudinally therein. A second hook, secured to the rod member, engages the inside portion of the steering wheel at a point diametrically opposed to that of the first hook. A second elongated rod member is adapted to extend in telescopic fashion in a direction opposite to that of the other rod member.

Abstract: An automobile steering wheel lock consists of an elongated tube member, a housing, an elongated rod member and a lock mechanism. The improvement of the automobile steering wheel lock is in the lock mechanism which is inserted in a lower chamber of the housing. The lock mechanism is combined by a locking member, a sleeve, a bearing member and an actuator. The sleeve defining a hollow cylinder has a bottom groove mounted by a projection of the locking member. The bearing member having a bottom cylindrical projection retained by a powerful spring is capable of passing through the sleeve and being inserted in a central circular groove of the projection of the locking member.

Abstract: An antitheft device for attachment to a steering wheel of an automobile comprising an elongated body member having a passageway extending axially therein. A first hook is secured to the body member for engagement with a portion of the steering wheel. The first hook engages the wheel from the inside of the rim, with the body member extending outward beyond the periphery of the steering wheel. An elongated tubular member adapted to move in telescopic fashion within the passageway of the body member, along it axis, includes a second hook, secured thereto, for engaging the inside portion of the steering wheel at a point diametrically opposed to the first hook. A rod membr, adapted to move in telescopic fashion within the tubular member, is provided for preventing the steering wheel from complete rotation.
