Claim 1

A combination handle bar assembly for a velocipede and a knuckle joint for securing a handle bar of said assembly to a steering shaft of the velocipede, said assembly comprising a tubular handle bar having a generally longitudinally extending central portion with surface deformations, said deformations extending inwardly of the handle bar, said combination further comprising: a. a connection sleeve extending longitudinally around said handle bar so as to surround said central portion, said sleeve being formed of plastic material molded about said handle bar so as to extend into said deformations and so as to comprise means for preventing rotation of the sleeve about the handle bar, said sleeve having longitudinally extending ribs which extend generally radially relative to said handle bar; b. a first knuckle part to be fixed to said steering shaft, said first knuckle part having a recess; c. a second knuckle part having a recess, said second knuckle part being adapted to be fixed to said first knuckle part so that the recesses of said knuckle parts cooperate to provide a passage within which said handle bar and said sleeve are located, at least one of said knuckle parts having a plurality of longitudinally extending channels which receive said ribs to prevent rotation of said sleeve, and said handle bar fixed thereto, about the longitudinal axes of said sleeve and said handle bar relative to said knuckle parts; and d. means for clamping said knuckle parts together so that said handle bar and said sleeve are clampingly fixed between said knuckle parts.
