Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
240 words
A lug nut tool in combination with a vehicular wheel, wherein the vehicular wheel includes a plurality of lug nuts radially spaced in a predetermined circle respective to an axis of the vehicular wheel, and the tool including a central housing hub, and the housing hub including a predetermined plurality of housing legs radially and fixedly mounted to the housing hub, and the housing hub including a central drive gear, wherein the central drive gear includes a coaxially mounted drive gear socket for receiving a torque application tool, wherein each of the predetermined pluralities of housing legs includes an intermediate gear in association with the central drive gear, and a terminal gear mounted within each housing leg in operative association with each intermediate gear, and an output shaft coaxially mounted to each intermediate gear extending orthogonally and exteriorly of a bottom surface of each housing leg, wherein each output shaft selectively receives a socket for mounting onto an associated lug nut, and wherein each output shaft is coaxially and fixedly mounted to a terminal gear shaft, wherein the terminal gear shaft is fixedly mounted to each terminal gear and is rotatably mounted within each housing leg orthogonal relative to each housing leg, and an upper terminal end of each terminal gear shaft includes an outwardly flared head cooperative with an upper head bearing, and a lower terminal end of each terminal gear shaft rotatably mounted within a lower head bearing.
Claim 2
Dependent Claim
240 words
A lug nut tool in combination with a vehicular wheel, wherein the vehicular wheel includes a plurality of lug nuts radially spaced in a predetermined circle respective to an axis of the vehicular wheel, and the tool including a central housing hub, and the housing hub including a predetermined plurality of housing legs radially and fixedly mounted to the housing hub, and the housing hub including a central drive gear, wherein the central drive gear includes a coaxially mounted drive gear socket for receiving a torque application tool, wherein each of the predetermined pluralities of housing legs includes an intermediate gear in association with the central drive gear, and a terminal gear mounted within each housing leg in operative association with each intermediate gear, and an output shaft coaxially mounted to each intermediate gear extending orthogonally and exteriorly of a bottom surface of each housing leg, wherein each output shaft selectively receives a socket for mounting onto an associated lug nut, and wherein each output shaft is coaxially and fixedly mounted to a terminal gear shaft, wherein the terminal gear shaft is fixedly mounted to each terminal gear and is rotatably mounted within each housing leg orthogonal relative to each housing leg, and an upper terminal end of each terminal gear shaft includes an outwardly flared head cooperative with an upper head bearing, and a lower terminal end of each terminal gear shaft rotatably mounted within a lower head bearing.
Claim 3
Dependent Claim
102 words
An apparatus as set forth in claim 1 wherein the central housing hub includes a first and second circumferential groove formed to an interior surface of the housing hub, wherein the circumferential grooves are arranged in a parallel relationship relative to one another and coaxially aligned relative to the housing hub, and the first and second groove mount a respective first and second bearing therewithin, and a cylindrical slot is in communication with the first and second bearing to permit lubrication of the first and second bearing through the cylindrical slot positioned between the central drive gear socket and the housing hub.
