US3894207A — Hand grip type vehicle directional signal control…

Claim 1

Independent Claim 208 words

A vehicle directional control mounted within a steering handlebar carried upon a vehicle comprising: an elongate hollow body; means defining a longitudinal slot within the wall of the body; an electrical contact on the body operatively connected to a signal light; a rotatable shaft contained at least partly within the body and having an electrical contact pin thereon; a source of electrical power upon the vehicle and having a terminal within the handlebar which is operatively connected to the electrical contact pin on the rotatable shaft; a first cam fixed on the rotatable shaft; a second cam slideably mounted on the rotatable shaft and having an ear projecting into the longitudinal slot in the body; position defining means including a spring interposed between the slideable cam and one end of the hollow body which defines a signal-off position of the control; and a grip attached to the rotatable shaft for applying a torque to the shaft to rotate the shaft within the hollow body thereby coupling the electrical power source to the directional light on the body electrical contact via the shaft mounted contact pin, the positioning means being operable to automatically restore the control to the signal-off position when torque forces applied to the grip are released.

Claim 2

Dependent Claim 208 words

A vehicle directional control mounted within a steering handlebar carried upon a vehicle comprising: an elongate hollow body; means defining a longitudinal slot within the wall of the body; an electrical contact on the body operatively connected to a signal light; a rotatable shaft contained at least partly within the body and having an electrical contact pin thereon; a source of electrical power upon the vehicle and having a terminal within the handlebar which is operatively connected to the electrical contact pin on the rotatable shaft; a first cam fixed on the rotatable shaft; a second cam slideably mounted on the rotatable shaft and having an ear projecting into the longitudinal slot in the body; position defining means including a spring interposed between the slideable cam and one end of the hollow body which defines a signal-off position of the control; and a grip attached to the rotatable shaft for applying a torque to the shaft to rotate the shaft within the hollow body thereby coupling the electrical power source to the directional light on the body electrical contact via the shaft mounted contact pin, the positioning means being operable to automatically restore the control to the signal-off position when torque forces applied to the grip are released.

Claim 3

Dependent Claim 17 words

Apparatus according to claim 1 wherein said first cam has one slope relative to its longitudinal axis.

Claim 4

Dependent Claim 18 words

Apparatus according to claim 1 wherein said second cam has one sloped face relative to its longitudinal axis.

Claim 5

Dependent Claim 32 words

Apparatus according to claim 1 wherein the first And second cam each have a sloped face and maintain opposed face to face contact relative to all positions assumed by the rotatable shaft.

Claim 6

Dependent Claim 141 words

A self-cancelling directional signal control having an on and off position, the control mounted within a vehicle having a handlebar and comprising: a body defining a cylindrical cavity; an elongate rotatable shaft normally biased to an off position mounted within said cavity and including an electrical contact bar on one end of said shaft; a source of electrical power mounted on the said vehicle and having a terminal within the handlebar, the terminal being operatively connected to said contact bar; a fixed electrical contact mounted on said body defining an on position; a grip connected to the rotatable shaft whereby application of a torque force to said grip rotates said shaft into the on position; and plural cam means within said cavity to automatically return said shaft to the off position, when the torque forces applied to the grip are released.

Claim 7

Dependent Claim 141 words

A self-cancelling directional signal control having an on and off position, the control mounted within a vehicle having a handlebar and comprising: a body defining a cylindrical cavity; an elongate rotatable shaft normally biased to an off position mounted within said cavity and including an electrical contact bar on one end of said shaft; a source of electrical power mounted on the said vehicle and having a terminal within the handlebar, the terminal being operatively connected to said contact bar; a fixed electrical contact mounted on said body defining an on position; a grip connected to the rotatable shaft whereby application of a torque force to said grip rotates said shaft into the on position; and plural cam means within said cavity to automatically return said shaft to the off position, when the torque forces applied to the grip are released.

Claim 8

Dependent Claim 54 words

Apparatus according to claim 5 wherein the plural cam means comprises: a pair of opposed cams having mated sloped faces, the cams mounted on the rotatable shaft and the sloped faces of the cams being held in mating relation by a spring interposed between one cam and the inner end of the hollow body.

Claim 9

Dependent Claim 34 words

Apparatus according to claim 8 wherein one of the cams is slideably mounted on the rotatable shaft and includes an ear which slides within a longitudinal slot defined by the wall of the body.

Claim 10

Dependent Claim 187 words

A directional signal control mounted upon a vehicle having a handle-bar, the control comprising; an elongate hollow body mounted at least partially within the handle-bar; an electrical contact on the body operatively connected to a directional signal light; a source of electrical power mounted upon a vehicle and having a terminal within the handlebar; a rotatable shaft mounted within the body including a pin operatively connected to the electrical power source terminal to selectively connect the electrical power source to the directional light electrical contact on the body; means for manually applying a torque to the rotatable shaft whereby such rotation connects the electrical power source to the electrical contact on the body; and means within the hollow body to automatically disconnect the electrical power source from the electrical contact when such applied torque is released, the means including a first cam fixed on the shaft; a second cam slideable on the shaft; the first and second cam each having a sloped face relative to the longitudinal axis of the rotatable shaft, the sloped faces of the cams being in continuous contact throughout rotation of the shaft.

Claim 11

Dependent Claim 187 words

A directional signal control mounted upon a vehicle having a handle-bar, the control comprising; an elongate hollow body mounted at least partially within the handle-bar; an electrical contact on the body operatively connected to a directional signal light; a source of electrical power mounted upon a vehicle and having a terminal within the handlebar; a rotatable shaft mounted within the body including a pin operatively connected to the electrical power source terminal to selectively connect the electrical power source to the directional light electrical contact on the body; means for manually applying a torque to the rotatable shaft whereby such rotation connects the electrical power source to the electrical contact on the body; and means within the hollow body to automatically disconnect the electrical power source from the electrical contact when such applied torque is released, the means including a first cam fixed on the shaft; a second cam slideable on the shaft; the first and second cam each having a sloped face relative to the longitudinal axis of the rotatable shaft, the sloped faces of the cams being in continuous contact throughout rotation of the shaft.
