Abstract

This invention relates generally to windshield assemblies and windshield mounting systems for motorcycles, and in particular, to a manually adjustable and readily removable windshield system primarily intended for use with motorcycles, scootors, and the like.

Claims

1. A windshield mounting assembly for a motorcycle windshield or the like, said assembly comprising, in combination, a clamp portion adapted to be snugly received over the handlebar portion of an associated cycle, said clamp portion also including means for positioning a portion of a windshield brace assembly for rotation through a range of angular adjustment positions, a shield brace assembly having one end portion adapted to be removably positoned with respect to said clamp, said end also being arranged to prevent radial movement of said one brace end when said brace assembly is positioned for adjustment, a fastener adapted to cooperate with said clamp in securing said one brace end, said shield brace assembly further including cooperating portions also arranged for movement through a range of adjustment positions, and means for locking said cooperating portions to said brace in a desired position of adjustment, one of said cooperating portions having means on a free end thereof for attachment to a portion of a cycle windshield, said one brace end and said clamp having interlockable means for preventing movement of said brace from a desired position of angular adjustment when said brace end and said clamp are fastened together, said fastener also being constructed and arranged for hand tightening so as to lock said brace end to said clamp in said desired position of angular adjustment.

2. A windshield mounting assembly as defined in claim 1, wherein said clamp portion further includes means for at least partially journalling a portion of said windshield brace assembly for rotation through said range of angular adjustment position.

3. A windshield mounting assembly as defined in claim 1, wherein said cooperating portions also arranged for movement through said range of adjustment positions comprise inner and outer shield brace elements arranged for telescoping movement with respect to each other.

4. A windshield mounting assembly as defined in claim 1 wherein said interlockable means comprises cooperating serrations lying along frusto-conical surfaces of said brace end and a portion of said clamp, respectively.

5. A windshield mounting assembly as defined in claim 4 wherein said interlockable radially extending cooperating serrations on a portion of said brace end and a portion of said clamp, respectively.

6. A windshield mounting assembly as defined in claim 1 wherein said interlockable means comprise first and second parts having opposed, annular beveled surfaces, said angular beveled surfaces having slightly different bevel angles so as to provide a snug fit when said first and second parts are urged into closely associated relation.

7. A windshield mounting assembly as defined in claim 1, wherein said clamp portion includes a first portion adapted to cooperate with said one end portion of said brace assembly, a second portion acting as a cap, and fasteners to hold said first and second portions together.

8. A windshield mounting assembly for a motorcycle windshield or the like, said assembly comprising, in combination, a clamp portion adapted to be snugly received over a portion of an associated cycle, said clamp also including means for at least partially journaling a portion of a windshield brace assembly for rotation through a range of positions, a shield brace assembly having one end portion adapted to be removably received axially over said journaling portion of said clamp to prevent radial movement of said one brace end, a fastener adapted to cooperate with said clamp in securing said one brace end, said shield brace assembly further including cooperating portions also arranged for movement through a range of positions, means for locking said cooperating portions of said brace in a desired position of adjustment, one of said cooperating portions having means on a free end thereof for attachment to a portion of a cycle windshield, said one brace end and said clamp having interlockable means for preventing movement of said brace from a desired position of angular adjustment when said brace end is snugly held between said fastener and said clamp, said fastener also including means thereon for hand tightening so as to lock said brace in said desired position of angular adjustment.

9. A windshield mounting assembly for a motorcycle windshield or the like, said assembly comprising, in combination, a handlebar clamp portion adapted to be snugly received over a portion of the handlebar of an associated cycle, said handlebar clamp also including means for at least partially journaling a portion of a windshield brace assembly for rotation through a range of positions, a shield brace assembly having one end portion adapted to be removably received axially over said journaling portion of said clamp to prevent radial movement of said one brace end, a fastener adapted to cooperate with said clamp in securing said one brace end, said shield brace assembly further including cooperating portions arranged for telescoping movement between extended, withdrawn, and intermediate positions, means for locking said cooperating portions of said brace in a desired position of adjustment, one of said cooperating portions having means on a free end thereof for attachment to a portion of a cycle windshield, said one brace end and said clamp having interlockable means for securing said brace in a desired position of angular adjustment, said one end of said brace and a portion of said clamp having cooperating means to prevent movement of said one end of said brace when said brace end is locked between said fastener and said clamp, said fastener also including means thereon for hand tightening so as to lock said brace in said desired position of angular adjustment.

10. A windshield mounting assembly as defined in claim 9 wherein said handlebar clamp portion and said means for journaling said portion of said brace assembly comprise a handlebar clamping body, a stub journal, and a body cap unit.

11. A windshield mounting assembly as defined in claim 9 wherein said means for at least partially journaling said portion of said brace include a cylindrical stub shaft adapted to extend at least half way through said one end portion of said windshield brace so as to provide mechanical support therefor.

12. A windshield mounting assembly as defined in claim 9 wherein said interlockable means on said brace end and said clamp comprise a plurality of radially extending serrated surfaces constructed and arranged so as to interlock with one another.

13. A windshield mounting assembly as defined in claim 9 wherein said interlockable means on said brace end and said clamp comprise cooperating serrated surfaces lying respectively on frusto-conical surface portions of said clamp and said brace end.

14. A windshield mounting assembly as defined in claim 9 wherein said means for locking said portions of said brace in said position of adjustment comprise a compression sleeve and lock nut.

15. A windshield mounting assembly as defined in claim 9 wherein said means on said free end of said brace portion for attachment to a portion of a cycle windshield comprises the ball portion of a ball-and-socket mounting arrangement.

16. A windshield mounting assembly as defined in claim 9 wherein said fastener comprises a composite unit having a threaded shank and an enlarged diameter head portion, said head portion having a reduced diameter stub thereon for at least partially journalling a portion of said brace end.
