Abstract
An antitheft device adapted for attachment to the valve stem of an inflated vehicle tire may comprise: a plunger assembly including a plunger engageable with a valve core of the valve stem and axially movable relative thereto for forcing the valve core to an open position releasing air from the tire; and an actuator assembly including a cam member radially movable with respect to the axis of the plunger in response to rotation of the vehicle tire, from a passive position to an active position forcing the plunger toward opening of the valve core.
Claims13
An antitheft device adapted for attachment to the valve stem of an inflated vehicle tire comprising:
- housing means;
- plunger means including a plunger engageable with the valve core of said valve stem and axially movable relative thereto between a first terminal position not interfering with the closure of said valve core and a second terminal position forcing said valve core to an open position releasing air from said tire;
- and
- actuator means carried within said housing means including a cam member, radially movable with respect to the longitudinal axis of said plunger, in response to rotation of said vehicle tire, from a passive position to an active position forcing said plunger toward said second terminal position.
An antitheft device adapted for attachment to the valve stem of an air-inflated vehicle tire comprising:
- a plunger assembly threadedly connected to said valve stem and including a plunger engageable with the valve core of said valve stem axially movable relative thereto from a first position not interfering with the closure of said valve core to a second position forcing said valve core to an open position releasing air from said tire;
- an actuator assembly including a cam member mounted for radial movement with respect to the longitudinal axis of said plunger member and movable in response to rotation of said vehicle tire from a passive position to an active position engaging and forcing said plunger to said second position;
- a housing assembly for surrounding said plunger assembly and said actuator assembly preventing access thereto;
- and
- a locking assembly selectively locking said housing assembly around said plunger and actuator assemblies.
