Abstract
A coupling assembly adapted for releasably connecting a sidecar to a motorcycle includes a first coupling member attached to the motorcycle and having a ball-shaped portion with a first lateral dimension adjacent to second portions with a second lateral dimension greater than the first lateral dimension. A second coupling member is attached to the sidecar and has a bell-shaped configuration. Retaining means for engaging the ball-shaped portion of the first coupling member includes a plurality of fingers resiliently expandable to the second lateral dimension to receive the ball-shaped portion and contractable to the first lateral dimension to substantially enclose the ball-shaped portion. Screw means extending through the second coupling member draws the retaining means into the second coupling member. In this position the second coupling member prevents the expansion of the fingers from the first lateral dimension to the second lateral dimension thereby coupling the sidecar to the motorcycle.
