ABSTRACT:
A servicing stand for three wheeled vehicles of the motorcycle type includes a horizontal base which may be supported by casters and a pair of support brackets pivotally mounted to the rearward and forward ends of the base. Each of the brackets can swing from a retracted position through, and slightly past vertical to an extended position. A spring connected between the remote end of the forward bracket and the base urges the forward bracket toward its extended position. A linkage mechanism operatively couples the lower end of the rearward bracket to a releasable clamp mechanism which is utilized for holding the forward bracket in its collapsed position when the rearward bracket is also in its collapsed position. In this configuration, the servicing stand can be rolled underneath the three wheeled vehicle from behind, between its rear two wheels. A pair of C-shaped members at the upper end of the rearward bracket will then engage the rear axle of the vehicle. Thereafter, rearward pulling of the vehicle relative to the servicing stand will cause the clamping mechanism to release, permitting the forward bracket to swing upwardly until its upper end engages the underside of a portion of the vehicle adjacent its motor. Further rearward pulling of the vehicle relative to the servicing stand will cause the forward and rearward brackets to swing past verticle to their extended positions, raising the vehicle off the ground so that it can be readily serviced or moved around on the mobile stand.
