Filed:

Feb 27, 1975

Appl. No.:

5/553731

Inventors:

Ronald Lloyd Doll - Santa Monica CA
Robert Arthur Peterson - West Los Angeles CA

Assignee:

Spirit of America, Incorporated - Gardena CA

International Classification:

B62K 2712

US Classification:

280203

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.

International Classification:

B62J 500

US Classification:

362 72

Abstract:

A motorcycle headlight tilt control cooperates with wind deflecting fairing. It includes: (a) support means supporting the headlight structure to the fairing so that the headlight is tiltable to tilt the headlight forward beam up and down, (b) a manual control on the fairing, and (c) other means connected with the headlight structure and the manual control to controllably tilt the headlight in response to manual operation of said control, (d) there being a spring acting to transmit force biasing said headlight structure in a tilt direction.
