Claim 1
Independent Claim
275 words
A direction-signal-cancelling mechanism releasably assembled in a direction-signal-indicating apparatus that includes a latch means, for use in a vehicle which has a steering wheel having a counterbore, and a steering shaft, comprising an axially projecting tubular column having an integrally formed base member and having a bore diameter sufficient for said steering shaft to extend therethrough, a hollow annular cam member having a bore diameter sufficient for the steering shaft to extend therethrough and provided integrally at its periphery with a flange and with at least one axially extending cam lobe and at its upper end with at least one axially upwardly extending pin which is integral with said cam member and engageable with said counterbore of said steering wheel for interconnecting the cam member and the steering shaft through the steering wheel when said wheel is rotated until said pin and counterbore come into alignment with each other, said tubular column and said cam member being insertedly mounted on each other and having means to permit said cam member to be axially slidable and rotatable, the aforementioned cam lobe projecting radially outwardly for engagement with said latch means to effect automatic cancelling of the vehicle''s direction signals, one of said tubular column and said cam member being provided with at least one slit opening, spring means yieldably supported between said flange provided on said cam member and the tubular column so as to yieldably urge the cam member as a whole axially upwardly towards the steering wheel, and a flange provided on one of said tubular column and said cam member so as to limit the extent of said movement of said cam member.
Claim 2
Dependent Claim
275 words
A direction-signal-cancelling mechanism releasably assembled in a direction-signal-indicating apparatus that includes a latch means, for use in a vehicle which has a steering wheel having a counterbore, and a steering shaft, comprising an axially projecting tubular column having an integrally formed base member and having a bore diameter sufficient for said steering shaft to extend therethrough, a hollow annular cam member having a bore diameter sufficient for the steering shaft to extend therethrough and provided integrally at its periphery with a flange and with at least one axially extending cam lobe and at its upper end with at least one axially upwardly extending pin which is integral with said cam member and engageable with said counterbore of said steering wheel for interconnecting the cam member and the steering shaft through the steering wheel when said wheel is rotated until said pin and counterbore come into alignment with each other, said tubular column and said cam member being insertedly mounted on each other and having means to permit said cam member to be axially slidable and rotatable, the aforementioned cam lobe projecting radially outwardly for engagement with said latch means to effect automatic cancelling of the vehicle''s direction signals, one of said tubular column and said cam member being provided with at least one slit opening, spring means yieldably supported between said flange provided on said cam member and the tubular column so as to yieldably urge the cam member as a whole axially upwardly towards the steering wheel, and a flange provided on one of said tubular column and said cam member so as to limit the extent of said movement of said cam member.
Claim 3
Dependent Claim
140 words
A direction-signal-cancelling mechanism releaseably assembled into a direction-signal-indicating apparatus in a vehicle as claimed in claim 1, in which said tubular column has the smaller bore diameter than the cam member and is insertedly mounted on the latter, and in which there is provided a plurality of slits extending axially downwardly from the upper end of the tubular column, said spring means is yieldably supported between the flange provided on the cam member adjacent its lower end and the base portion of the tubular column in such a way that it surrounds the tubular column, and the flange, which limits the extent of movement of said cam member, is provided at the upper end of the tubular column and extends slightly radially outwardly so as to abut with a shoulder provided to the inner peripheral wall of the cam member.
Claim 4
Dependent Claim
101 words
A direction-signal-cancelling mechanism releasably assembled into a direction-signal-indicating apparatus in a vehicle as claimed in claim 1, in which said cam member has the smaller bore diameter than the tubular column and is insertedly mounted on the latter, said slit opening extends axially upwardly from the lower end of the cam member, and the flange, which limits the extent of movement of said cam member, is provided on the lower end of the cam member, whIch abuts with the lower end of the tubular column and cooperates with the latter for limiting the extent of said movement of said cam member.
