Abstract
The device transmits and mechanically amplifies input torque into increased output torque to facilitate such chores as tightening or loosening wheel lug nuts, and cranking a rotary mechanical jack. When used to tighten or loosen a wheel lug nut, the device is preferably anchored in place by attachment to a wheel lug nut other than the lug nut being tightened or loosened. When used to crank a mechanical jack, the device is preferably anchored in place by use of a crank handle, and the device is operated by use on an auxiliary crank. The inptut torque to the device can be supplied by hand or by an electric motor operated by battery power transmitted via a plug fitted into the socket of a cigarette lighter. The device is compact and can be readily used, even by physically weak or infirm persons.
Claims12
A device adapted for increasing rotary torque, which device comprises:
- (a) at least two laterally disposed plates in spaced-apart substantially parallel planar alignment defining a space therebetween;
- (b) gearing adapted to receive and amplify an input rotary torque, and to provide an amplified output rotary torque, at least a portion of said gearing being disposed within said space;
- (c) means for applying input rotary torque to said gearing;
- (d) means, including an output socket having an axis, for delivering amplified output rotary torque from said gearing to an object to be rotated;
- (e) an arm having an inner end portion, said arm being pivotally supported at said inner end portion within said space at a locus such that a portion of said arm extends beyond the edge of said plates;
- and
- (f) a holding socket having an axis, for anchoring the device in one or more operating spatial positions during application of the input rotary torque, said holding socket being attached to said portion of said arm that extends beyond the edge of said plates such that the linear distance between the axis of said holding socket and the axis of said output socket is adjustable by rotation of said pivotally supported arm.
A device for loosening or tightening a wheel lug, which device comprises:
- (a) at least two laterally disposed plates in spaced-part substantially parallel planar alignment defining a space therebetween;
- (b) gearing adapted to receive and amplify an input rotary torque, and to provide an amplified output rotary torque, at least a portion of said gearing being disposed within said space;
- (c) means for applying input rotary torque to said gearing;
- (d) means, including an output socket having an axis, for delivering amplified output rotary torque from said gearing to the wheel lug to be loosened or tightened;
- (e) an arm having an inner end portion, said arm being pivotally supported at said inner end portion within said space at a locus such that a portion of said arm extends beyond the edge of said plates;
- and
- (f) a holding socket having an axis, for anchoring the device in at least one operating spatial position onto a wheel lug other than the wheel lug to be loosened or tightened during application of the input rotary torque, and holding socket being attached to said portion of said arm that extends beyond the edge of said plates such that the linear distance between the axis of said holding socket and the axis of said output socket is adjustable by rotation of said pivotally supported arm.
