Abstract: A carriage includes a carriage frame having a wheeled rear frame portion and a front wheel-carrying frame portion. The front wheel-carrying frame portion has a lowermost section that defines a vertical accommodating hole which extends in an axial direction. A front wheel unit includes a fork mounting member disposed rotatably in the accommodating hole and having a fork connecting portion that extends downwardly and outwardly of the accommodating hole, and a retaining portion opposite to the fork connecting portion in the axial direction. A fork unit has an upper end fixed to the fork connecting portion of the fork mounting member and co-rotatable therewith, and a lower end with a wheel mounted rotatably thereon about a horizontal axis. A locking member is provided on the lowermost section of the front wheel-carrying frame portion for retaining rotatably the retaining portion of the fork mounting member in the accommodating hole.

Abstract: A brake device includes a shoe holder, and a brake shoe held by the shoe holder. The brake shoe has a plurality of outwardly projecting brake parts, a plurality of grooves each of which is formed between two adjacent ones of the brake parts and each of which is defined by a pair of groove walls, a plurality of flat contact faces formed on the brake parts, respectively, and spaced apart by the grooves, and a pair of buffer faces formed at two opposite ends of each of the contact faces to connect each of the contact faces to two adjacent ones of the groove walls. Each of the buffer faces extends inwardly of the corresponding one of the contact faces.

Abstract: A bicycle brake device includes opposing first and second brake arms which have respective fixed lower ends and movable upper ends. Two seats support the fixed lower ends. Two brake pads are mounted on the brake arms between the upper and lower ends. A brake cable extends through and engages the upper end of the second brake arm. A directing member directs the brake cable from the upper end of the second brake arm toward the first brake arm. The directing member includes a ring plate which is connected to the upper end of the first brake arm and which has a hole for threading the brake cable therethrough. A simultaneous movement member transmits the movement of the first brake arm to the second brake arm, thereby evenly pressing a rim of a bicycle wheel during a braking operation.

Abstract: A locking device for use in a bicycle brake system in order to retain a hand-operated brake lever thereof in a braked state includes a locking member of resilient material, and a bearing device for bearing the locking member on the brake lever. The brake system includes a mounting seat fixed on a bicycle handlebar for connecting a brake cable to the brake lever. The brake lever has a first end mounted pivotally to the mounting seat and turnable about a first axis. The locking member includes a pressure bearing portion, a pair of spaced bracing arm portions which extend traversely and respectively from two ends of the pressure bearing portion, and a pair of leg portions which extend inwardly and respectively from the bracing arm portions. The bearing device includes a pair of pivot holes formed in two opposite lateral walls of the brake lever to receive the leg portions therein such that the pressure bearing portion and the leg portions of the locking member are generally parallel to the first axis.

Abstract: A brake arm for a brake device of a bicycle includes first and second arm members and a locking unit. The first arm member has an elongated arm body with an upper end portion, a lower end portion and a shoe mounting portion between the upper and lower end portions. The upper end portion is formed with a threaded hole. The lower end portion is adapted to be secured pivotally on the bicycle. The mounting portion has a brake shoe attached thereto. The second arm member is formed as an elongated member with first and second end portions and an intermediate portion between the first and second end portions. The second arm member is provided with a mounting hole unit which extends from the first end portion toward the second end portion. The second end portion of the second arm member is provided with a wire attaching unit that is adapted to be connected operably to the brake device.

Abstract: A brake shoe assembly for a bicycle brake device includes a brake shoe with an inverted U-shaped mounting seat and a brake pad fixed to the mounting seat. A U-shaped connecting seat is received in the mounting seat. The length of the connecting seat is smaller than that of the mounting seat. At least two pairs of transversely aligned guiding slots are formed in two opposite side walls of the connecting seat. At least one of the pairs of the guiding slots has two first upwardly inclined lower sections and two wavy sections connected to the respective first lower sections. The remaining of the pairs of guiding slots have two second upwardly inclined lower sections and two linear sections connected to the respective second lower sections. At least two rivets are fixed respectively to the mounting seat and at least one of the rivets passes through at least one of the guiding slots. The remaining of the rivets pass through the remaining pairs of the guiding slots.

Abstract: A hanger device is used to interconnect a pull cable and a yoke cable in a bicycle brake assembly and includes a vertical guide rod which is adapted to be mounted to a fork portion of a bicycle frame. A slidable member is mounted slidably on the guide rod and is adapted to be connected to the pull cable. The slidable member is formed with a transverse receiving groove that is adapted to receive an intermediate portion of the yoke cable therein.

Abstract: A brake lever includes two separate sections which are connected to one another by an engaging screw to form an angle between two connected ends of the two sections.

Abstract: A bicycle brake device includes a curved brake arm that is formed with an elongated slot, an annular retaining seat that has a front end which is formed with a pair of diametrically opposite retaining notches, an annular support seat that has a rear uneven friction face which abuts against one side of the brake arm, a spring unit that is disposed in the support seat to bias the support seat away from the retaining seat, a washer that is provided with an uneven friction face which abuts against an opposite side of the brake arm, and a bolt that has a spherical head and a threaded shank. The threaded shank extends through the retaining seat, the spring unit, the support seat, the elongated slot of the brake arm and the washer. A portion of the spherical head extends into the retaining seat.
