Claim 3

In combination with a cambering vehicle having an upright steering column supporting a pair of rearwardly extending trailing arms for pivotal movement about a first axis which extends tranversely to the longitudinal axis of the vehicle, a mechanical cambering device for interconnecting the trailing arms so they move in substantially equal and opposite directions relative to the steering column when the vehicle is leaned into a turn, said cambering device comprising a crank member, a bracket carried by said steering column for supporting said crank member for rotational movement about a second axis spaced rearwardly from said first axis and extending transversely to the longitudinal axis of said vehicle, said crank member having a pair of offset legs which extend in opposite direction, one of said legs being offset from said second axis a distance greater than the other of said legs, and each of said trailing arms having a slot formed therein for receiving one of said legs so that pivotal movement of one of said trailing arms about said first axis in one direction results in said crank member being rotated about the second axis to cause the other of said trailing arms to be pivoted about the first axis in a direction opposite to said one direction.

Claim 4

In combination with a cambering vehicle having an upright steering column supporting a pair of rearwardly extending trailing arms for pivotal movement about a first axis which extends tranversely to the longitudinal axis of the vehicle, a mechanical cambering device for interconnecting the trailing arms so they move in substantially equal and opposite directions relative to the steering column when the vehicle is leaned into a turn, said cambering device comprising a crank member, a bracket carried by said steering column for supporting said crank member for rotational movement about a second axis spaced rearwardly from said first axis and extending transversely to the longitudinal axis of said vehicle, said crank member having a pair of offset legs which extend in opposite direction, one of said legs being offset from said second axis a distance greater than the other of said legs, and each of said trailing arms having a slot formed therein for receiving one of said legs so that pivotal movement of one of said trailing arms about said first axis in one direction results in said crank member being rotated about the second axis to cause the other of said trailing arms to be pivoted about the first axis in a direction opposite to said one direction.

Claim 5

In combination with a cambering vehicle having an upright steering column supporting a pair of rearwardly extending trailing arms for pivotal movement about a first axis which extends transversely to the longitudinal axis of the vehicle, a mechanical cambering device located between said pair of trailing arms for interconnecting the latter so the trailing arms move in opposite directions through substantially equal angles about their axes relative to the steering column when the vehicle is leaned into a turn, said cambering device comprising a crank member mounted on said steering column for rotational movement about a second axis spaced rearwardly from and parallel to said first axis, said crank member including an elongated body portion terminating at each end thereof with an offset leg, the leg at one end of said crank member taking the form of a cross bar having opposed ends and being movable towards and away from said body portion, a bracket normally fixed with said steering column for supporting said body portion between said pair of trailing arms for rotation about said second axis, each of said trailing arms having an elongated slot formed therein for receiving one leg of said crank member so that pivotal movement of one of said trailing arms about said first axis in one direction results in said crank member being rotated about the second axis to cause the other of said trailing arms to be pivoted about the first axis in a direction opposite to said one direction, and said bracket having a curved guide slot formed therein for receiving one of said opposed ends of said cross bar for controlling angular movement of the associated trailing arm as said trailing arms move in opposite direction.

Claim 6

In combination with a cambering vehicle having an upright steering column supporting a pair of rearwardly extending trailing arms for pivotal movement about a first axis which extends transversely to the longitudinal axis of the vehicle, a mechanical cambering device located between said pair of trailing arms for interconnecting the latter so the trailing arms move in opposite directions through substantially equal angles about their axes relative to the steering column when the vehicle is leaned into a turn, said cambering device comprising a crank member mounted on said steering column for rotational movement about a second axis spaced rearwardly from and parallel to said first axis, said crank member including an elongated body portion terminating at each end thereof with an offset leg, the leg at one end of said crank member taking the form of a cross bar having opposed ends and being movable towards and away from said body portion, a bracket normally fixed with said steering column for supporting said body portion between said pair of trailing arms for rotation about said second axis, each of said trailing arms having an elongated slot formed therein for receiving one leg of said crank member so that pivotal movement of one of said trailing arms about said first axis in one direction results in said crank member being rotated about the second axis to cause the other of said trailing arms to be pivoted about the first axis in a direction opposite to said one direction, and said bracket having a curved guide slot formed therein for receiving one of said opposed ends of said cross bar for controlling angular movement of the associated trailing arm as said trailing arms move in opposite direction.

Claim 7

In combination with a cambering vehicle having an upright steering column supporting a pair of rearwardly extending trailing arms for pivotal movement about a first axis which extends transversely to the longitudinal axis of the vehicle, a mechanical cambering device for interconnecting the trailing arms so they move in substantially equal and opposite directions relative to the steering column when the vehicle is leaned into a turn, said cambering device comprising a crank member mounted on said steering column for rotation about a second axis spaced rearwardly from said first axis and extending transversely to the longitudinal axis of said vehicle, said crank member including an elongated body portion terminating at the opposed ends thereof with L-shaped end portions which extend in opposite directions and provide a pair of laterally extending legs, one of which is offset from said body portion a distance greater than the other of said pair of legs, a bracket having a sleeve portion normally fixed with said steering column for supporting said body portion between said pair of trailing arms for rotation about said second axis, each of said trailing arms having a slot formed therein for receiving a leg of one of said L-shaped end portions so that pivotal movement of one of said trailing arms about said first axis in one direction results in said body portion being rotated about the second axis to cause the other of said trailing arms to be pivoted about the first axis in a direction opposite to said one direction, and a lock device carried by said sleeve portion of said bracket for locking the latter to the steering column for normal operation of the vehicle and for releasing said bracket from said steering column so as to allow the steering column to pivot rearwardly towards the trailing arms about said first axis into a folded position to facilitate stowage of said vehicle.
