Patent ID: 8336913

Claim:
A steering device for decreasing a turning radius of a pallet jack, the pallet jack including a main wheel and an extensible wheel connected to a load supporting member, a first turning radius defined by the distance between the main wheel and the extensible wheel, the load supporting member positionable between a raised position and a lowered position, the steering device comprising: a first portion fixedly connected to the support member between the main wheel and the extensible wheel, the first portion including: surfaces defining first and second opposing apertures; and surfaces defining first and second slotted apertures; a second portion pivotally attached to the first portion, the second portion including: surfaces defining first and second opposing apertures, the apertures of the first portion cooperably alignable with the apertures of the second portion; and surfaces defining third and fourth opposing apertures cooperably alignable with the first and second slotted apertures of the first portion; a first axial member positionable through the apertures of the first portion and the apertures of the second portion to pivotally attach the second portion to the first portion; a second axial member positionable through the third and fourth apertures of the second portion and slideably engageable with the slotted apertures of the first portion; a spring disposed within the first portion, the spring biased against the second portion to urge the second portion to remain in a selected position; and a ground engageable roller at least partially disposed within the second portion, wherein positioning the support member towards the lowered position the ground engageable roller engages the ground causing the extensible wheel to disengage the ground whereupon the main wheel and the ground engageable roller define a second turning radius which is less than the first turning radius, whereupon the ground engageable roller contacting a lower cross member of a pallet, the second portion is urged against the biasing force of the spring to pivot toward the support member, wherein the amount of pivotal movement of the second portion relative to the first portion is defined by the length of the first and second slotted apertures.
