Abstract
A tool construction is set forth to include a central housing and a plurality of radially directed housing legs relative to the housing, wherein each leg mounts an output shaft driven through a central gear to effect simultaneous removal or assembly of lug nuts relative to an associated vehicular wheel.
Claims2
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.
