Abstract
An adjustable eccentric bracket assembly for a bicycle provided with at least two wedge surfaces in a body member designed to co-act with at least one wedge member having a wedge surface, where upon axial displacement of the wedge member relative to the body member, the wedge member is laterally displaced so as to selectively engage with an inner surface of a shell in which the body member is received.
Claims30
A bracket assembly for a pedal shaft of a bicycle frame comprising:
- a body member having a longitudinal axis, to be positioned within the bicycle frame for receiving the petal shaft, said body member having:
- at least two body member wedge surfaces that are sloped with respect to the longitudinal axis of said body member;
- a bore having an axis eccentric to the longitudinal axis of said body member;
- at least one wedge member having a wedge surface co-planar with at least one of the at least two wedge surfaces of said body member;
- and
- a wedge driver for axially displacing said at least one wedge member relative to said body member;
- wherein when said at least one wedge member is displaced axially, said at least one wedge member is laterally displaced relative to said body member such that said bracket assembly is engageable with an internal surface of the bicycle frame.
A bracket assembly comprising:
- a body member to be positioned within an opening, said body member having:
- a bore having a longitudinal axis eccentric to a longitudinal axis of said body member;
- a first outer surface having a first diameter d1;
- a second outer surface having a second diameter d2, wherein d1 is larger than d2;
- a body member wedge surface that is sloped with respect to the longitudinal axis of said body member;
- at least one wedge member having a wedge surface co-planar with said body member wedge surface;
- a wedge driver for moving said at least one wedge member relative to said body member;
- wherein when said at least one wedge member is displaced axially, said at least one wedge member is laterally displaced relative to said body member such that bracket assembly is engageable with an internal surface of the opening.
A bracket assembly for mounting a shaft within a machine comprising:
- a body member having a longitudinal axis, to be positioned within the machine for receiving the shaft, said body member having:
- at least two body member wedge surfaces that are sloped with respect to the longitudinal axis of said body member;
- a bore having an axis eccentric to the longitudinal axis of said body member;
- at least one wedge member having a wedge surface co-planar with at least one of the at least two wedge surfaces of said body member;
- and
- a wedge driver for axially displacing said at least one wedge member relative to said body member;
- wherein when said at least one wedge member is displaced axially, said at least one wedge member is laterally displaced relative to said body member such that said bracket assembly is engageable with an internal surface of the machine.
A bracket assembly for a pedal shaft of a bicycle comprising:
- a body member having a longitudinal axis, to be positioned within the bicycle frame for receiving the petal shaft, said body member having a body member wedge surface that is sloped with respect to the longitudinal axis of said body member;
- and a bore having an axis offset from the longitudinal axis of said body member;
- a wedge member axially movable relative to said body member, said wedge member having a wedge member wedge surface co-planar with the wedge surface of said body member;
- a wedge driver for axially moving said wedge member relative to said body member;
- a wedge driver recess formed in the wedge member wedge surface for receiving said wedge driver;
- and
- a wedge surface recess formed in the wedge member wedge surface for reducing the surface area of the wedge member wedge surface contacting the body member wedge surface.
