Abstract
Abstract A steering handle for a two-wheeled vehicle is attached to a support member facing the upper end of a front wheel fork attached to a steering stem. The support member is rotatably mounted on the steering stem and the fork and support member have opposed crenelations which are engageable and disengageable, so that the steering handle support member can be rotated either together with the upper end of the front wheel fork or independently thereof. The support member can be displaced either by a cap threaded on the stem or by a cam member pivoted thereon in order to mesh the crenelations.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
164 words
In a two wheel vehicle having a frame with a head pipe, and a steering stem rotatably mounted in the head pipe, an improvement comprising a front wheel fork attached to said steering stem for rotation therewith, a support member for a steering handle rotatably mounted on said stem, coupling means on said fork and support member having engaged and disengaged positions in which said fork and support member are respectively coupled for common rotation or said support member is rotatable on said stem independently of said fork, actuating means acting on said support member for engaging and disengaging the same and said fork, said actuating means comprising a cam handle pivotably supported with respect to the stem and acting on said support member to displace the same to engage the fork, said coupling means comprising opposed portions on said fork and support member having crenelations facing one another which are in meshed engagement when the fork and support member are in engaged position.
Claim 2
Dependent Claim
164 words
In a two wheel vehicle having a frame with a head pipe, and a steering stem rotatably mounted in the head pipe, an improvement comprising a front wheel fork attached to said steering stem for rotation therewith, a support member for a steering handle rotatably mounted on said stem, coupling means on said fork and support member having engaged and disengaged positions in which said fork and support member are respectively coupled for common rotation or said support member is rotatable on said stem independently of said fork, actuating means acting on said support member for engaging and disengaging the same and said fork, said actuating means comprising a cam handle pivotably supported with respect to the stem and acting on said support member to displace the same to engage the fork, said coupling means comprising opposed portions on said fork and support member having crenelations facing one another which are in meshed engagement when the fork and support member are in engaged position.
Claim 3
Dependent Claim
37 words
An improvement as claimed in claim 1 comprising resilient means between said fork and support member apart to the disengaged position, said actuating means acting on the support member to overcome the opposition of the resilient means.
Claim 4
Dependent Claim
37 words
An improvement as claimed in claim 1 wherein said stem is hollow and further comprising a support shaft secured to said stem and extending through said stem, said cam handle being pivotably mounted on the support shaft.
Claim 5
Dependent Claim
51 words
An improvement as claimed in claim 3 wherein said cam handle includes a cam portion constituted by first and second cam surfaces located at different distances from the pivot axis of the cam handle relative to the stem and an intermediate cam surface smoothly joining the first and second cam surfaces.
Claim 6
Dependent Claim
57 words
An improvement as claimed in claim 3 comprising a slidable cap on said support shaft, and a stopper member on said cam handle engaged with said cap to prevent pivotal movement of the cam handle, said cap being slidable to a position in which said stopper member is released and the cam handle can be pivotably moved.
