Abstract:
A lug wrench which when assembled comprises a single tool incorporating: at least one pair of drive heads or socket heads for co-operation with or engagement of a wheel nut; at least one pair of lever bars for applying torque to the respective drive heads or socket heads of a pair, one of the lever bars being or capable of becoming when fully extended of greater length than the other; a non-adjustable one-way drive element associated with one socket head or drive head of each pair; andwhen the lug wrench is configured in such a way that the respective drive heads or socket heads of a pair are capable of transmitting torque and are disposed approximately perpendicular to one another, there is an inherent limitation on the relative maximum torque which can be applied by the drive heads or socket heads of the pair; the torque which can be applied in the nut loosening direction by the drive head or socket head having an associated non-adjustable one-way drive element is greater than can be applied in the nut tightening direction by the other drive head or socket head of the pair, under any optional lug wrench configuration which may be available other than by the addition of an extension bar connected to a drive head or socket head.
