<p>This invention relates to a security device for use in preventing the unauthorised rotation of a wheel such as a steering wheel, an undriven wheel of a vehicle. The device is so arranged that while it may allow a limited movement to the wheel it prevents the wheel being turned through more than a fraction of a full turn and thus would prevent a vehicle being driven away or a machine or appliance being turned on, or a boat being steered. The device comprises a boss plate, two pivoted callipers which wrap around the vehicle wheel and an adjustable calliper. Stops limit movement of the pivoted callipers. The adjustable calliper slides in a bracket and can be locked in a number of different positions by a padlock engageable in holes provided. An extension of the adjustable calliper will engage the ground or part of the vehicle and prevent unauthorised movement.</p> |
