Abstract
Abstract A device for holding the steering wheel of a vehicle against rotation is arranged to grip a sector of the wheel, and has a projecting element which abuts against part of the vehicle if any attempt is made to turn the wheel sufficiently to enable the vehicle to be driven. The device has a channel to receive the steering wheel sector, which is held therein by retaining means which is movable towards and away from the channel, and which can be locked in a retaining position by suitable locking means, but is releasable so that the device may be removed from the wheel and from the vehicle.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
247 words
A road vehicle anti-theft device comprising: a body having a channel formed along and open into one edge of the body, said channel being shaped to receive a portion of a vehicle steering wheel, the channel including means for engaging the outer periphery of the steering wheel at at least two points along the length of the channel, the body being movable in a radial direction relative to a vehicle steering wheel onto said vehicle steering wheel, receiving said portion of the steering wheel in the channel, retaining means slidably mounted in the body and including hookshaped means movable from an extended position spaced from the open side of the channel toward the open side of the channel to essentially close the said open side of the channel at at least two points along the length of the channel so as to retain the steering wheel in the channel, said retaining means, in cooperation with said channel, forming a means for preventing (a) radial movement of the body off of the steering wheel, (b) substantial turning movement of the body about an axis in the plane of the steering wheel and (c) substantial turning movement of the body in the plane of the steering wheel, locking means for locking the retaining means in the retaining position, and an element connected to the body and projecting approximately radially relative to the steering wheel to prevent the wheel from being turned sufficiently to allow the vehicle to be driven.

Claim 3
Dependent Claim
24 words
A device according to claim 1, wherein the hook means has two hooks with free ends which retract into the body of the device.
Claim 4
Dependent Claim
40 words
A device according to claim 1 wherein the channel is opened radially inwardly relative to the steering wheel and is hence adapted to be introduced over the wheel from beyond the periphery of the wheel by a radially inward movement.
Claim 5
Dependent Claim
29 words
A device according to claim 1 wherein the retaining means is movable towards said channel against spring pressure, so that it springs outwardly when released by the locking means.
Claim 6
Dependent Claim
43 words
A device according to claim 4 wherein the retaining means is freely movable into retaining position under hand force even when the locking means is in locked position, but is automatically locked against movement in the opposite direction until the lock is released.
Claim 7
Dependent Claim
124 words
A road vehicle anti-theft device having a body with a channel open along one side thereof to receive a sector of a vehicle steering wheel, hook-shaped retaining means movable against spring pressure towards the open side of the channel to retain the wheel sector therein, two hooks on said retaining means, each having a free end which retracts into the body of the device, locking means to lock the retaining means in the retaining position, springs means to urge the retaining means away from the channel when the locking means is released, and an element connected to the body and projecting approximately radially from the steering wheel so as to prevent the wheel from being turned sufficiently to allow the vehicle to be driven.
Claim 8
Dependent Claim
124 words
A road vehicle anti-theft device having a body with a channel open along one side thereof to receive a sector of a vehicle steering wheel, hook-shaped retaining means movable against spring pressure towards the open side of the channel to retain the wheel sector therein, two hooks on said retaining means, each having a free end which retracts into the body of the device, locking means to lock the retaining means in the retaining position, springs means to urge the retaining means away from the channel when the locking means is released, and an element connected to the body and projecting approximately radially from the steering wheel so as to prevent the wheel from being turned sufficiently to allow the vehicle to be driven.
