摘要： An adjustable handlebar for a bicycle according to the invention comprises two handlebar members whose adjacent ends are pivotally supported by two bolts whose extended axes are crossing in front of the bicycle, gear teeth formed in the adjacent ends of the handlebar members so as to pivotally move one handlebar member by pivotally moving the other handlebar member, two sets of isosceles triangle-shaped thrust serrations at adjacent ends of the handlebar members and an upper portion of a handlebar stem, thereby anchoring the handlebar members when the bolts are tightened and moving the adjacent ends of the handlebar members away from the upper portion of the handlebar stem when the bolts are loosened and the handlebar members are rotated, and a cam and cam follower assembly having a lever for engaging and disengaging the serrations, thereby simply changing positions of handlebar members symmetrically. The upper portion of the handlebar stem is formed by a rear part and a front part pivotally movable relative to the rear part in a substantially vertical direction about a substantially horizontal axis in transverse direction of the bicycle and clamped to the rear part by the clamping means, thereby enabling inclined angles of grips of the handlebar to be changed.

摘要： A frame for a folding bicycle includes a base frame having a triangular configuration, the base frame having a pair of back forks and a pair of lower stays joined to a pair of end members respectively. A main pipe is interconnected between the pair of back forks and the pair of lower stays, and a quadric link is connected to the triangular base frame. The guadric link includes the main pipe, a seat pipe, a front pipe, and an upper stay, along with a first pivot pivotally connecting the main pipe and the seat pipe to provide pivotal movement of the seat pipe relative to the main pipe, a second pivot pivotally connecting the main pipe and the front pipe to provide pivotal movement of the front pipe relative to the main pipe, a third pivot pivotally connecting the front pipe and the upper stay to provide pivotal movement between the front pipe and the upper stay, and a fourth pivot pivotally connecting the seat pipe and the upper stay to provide pivotal movement between the seat pipe and the upper stay. The quadric link further includes a foldable link extending between the first and the third pivots, the foldable link having a first position which maintains the quadric link in an uncollapsed condition and a second position in which the quadric link is in a collapsed condition. The foldable link further includes an operable device for maintaining the quadric link in the uncollapsed condition, the operable device being manually operable to permit the quadric link to be collapsed and folded to the collapsed condition.

摘要： A caliper brake for a bicycle includes brake members formed as side-pull type caliper arms. The brake members are pivotally supported on a frame of the bicycle and support at ends thereof brake shoes. A pulley is rotatably provided on a free end of one of the brake members. A brake operating wire is connected to brake operating levers at handlebars of the bicycle. The brake operating wire consists of an inner wire and an outer wire. The inner wire extends about the pulley to form a brake operating force acting point of the one brake member by the pulley at which brake operating force acts on the one brake member. One end of the inner wire is connected to the other brake member, and one end of the outer wire is anchored to a free end of the other brake member to form a brake operating force acting point of the other brake member by the anchored point at which brake operating force acts on the other brake member. Operating radii between pivotal points of both the brake members and the brake operating force acting points are made as small as possible.

摘要： A caliper type brake for a bicycle, which includes brake members pivotally supported by a frame of the bicycle for supporting brake shoes adapted to be pressed to a rim of a wheel of the bicycle. Each of the brake members is shaped like a bell crank and has one end pivotally connected to the frame of the bicycle and the other end supporting the brake shoe. An operating radius between a pivotal point of each of the brake members and a point of the brake member on which a brake operating force acts is made as small as possible. The brake further inlcudes a generally V-shaped connecting rod whose ends are connected to the brake members, respectively for applying the brake operating force to the brake member, a pulley rotatably provided at an intermediate portion of the connecting rod, and an operating wire extending about the pulley and having one end fixed to the frame of the bicycle.
