  • Publication number: 20010045330
    Abstract: A bicycle brake shoe, comprising: a support bar; a seat; a brake pad, which is mounted on the seat and for braking pressed against a wheel rim on a contact surface having a front end which faces an opposite movement of the wheel rim; a moving block, mounted on the seat close to the front end of the brake pad, projecting from the brake pad towards the wheel rim, pressed by a spring. The moving block is movable perpendicular to the contact surface of the brake pad and has a projecting surface which upon braking touches the wheel rim prior to the contact surface of the brake pad, scraping water, gravel and dirt from the wheel rim. Thus a braking effect unhampered by water or dirt is achieved.

  • Patent number: 5921363
    Abstract: A free wheel rotary body structure for use in a bicycle is disclosed. It includes a free wheel kernel having a pair of axially extending ratchet pawl bearings at diametrically opposite positions relative to each other and a pair of ring grooves. The rotary body structure also includes first and second sets of one-way clutches. Each of the one-way clutches includes a c-spring and a pair of ratchet pawls. The pair of c-springs are received in the pair of ring grooves, respectively, of the free wheel kernel, and the pairs of ratchet pawls are received in the diametrically opposing pawl bearings, respectively, of the free wheel kernel. The pair of ratchet pawls in the first set of one-way clutch are of different shapes and dimensions from the pair of ratchet pawls in the second set of one-way clutch, so as to form phase difference when one of each pair of the ratchet pawls is engaged with the ratchet teeth groove of the free wheel housing.

  • Patent number: 5913386
    Abstract: The present invention relates to a cushion mechanism for a brake of a bicycle, comprising a brake block, an elastomer, a sleeve, and an adjustable nut. The brake block includes an engaging end which extends through the elastomer and the sleeve and is engaged with the adjustable nut. Then the cushion mechanism is installed on a brake caliper. The cushion mechanism of the brake is constructed to prevent a sudden lock of the wheel upon an emergency brake and such an effect is achieved by mounting an elastomer between the brake block and the brake caliper. The elastomer is preset with pressure while being assembled. The preset pressure enables the elastomer to absorb a less force caused by braking when under normal braking operation; and enables the same elastomer to absorb excess force when the braking force exceeds the normal range. Thus, the braking force will not reduce, and the safety for the rider is secured.

  • Patent number: 5876159
    Abstract: A sprocket trimming method for a multi-stage sprocket assembly is disclosed which includes the steps of: (1) aligning the two sprockets at a gear shift position where a chain is escaping from one sprocket and engaging with another sprocket and is being tilted at a tilting angle; (2) using a computer aided design simulation to simulate how the gear shift operation is taking place and thus identify the portion of the sprocket tooth that will be overlapped and/or interfered with the chain when the chain is moved from an escaping sprocket tooth to an engaging sprocket tooth; and (3) trimming the overlapping and interference portion of the sprocket teeth to a depth according to the following equation: ##EQU1## wherein: D is the depth of the overlapping and interference portion of the sprocket teeth to be trimmed, w is the pitch width of the chain, Lc is the pitch length of the chain, .theta.

  • Patent number: 5865698
    Abstract: An improved rear derailleur for changing the gear ratio of a bicycle is disclosed. It includes a fixed member, a movable member, a parallelogram mechanism connecting the fixed member with the movable member, and a cable adjusting screw which is screwed to a screw socket fixed on the fixed member. The cable adjusting screw is connected to a first end of a cable, wherein the cable has a second end fixed to a movable member. The cam member comprises a guiding surface for guiding the cable between the cable adjusting screw and the movable member. The guiding surface of the cam member is structured substantially coinciding a portion of a fictitious circle centered at a rotating pin which connects an outer linkage of the parallelogram with a second end of the fixed member.

  • Patent number: 5732593
    Abstract: A bicycle speed changing apparatus comprises a support means, a cable winding means, a fixation plate, a high gear shifting means, a retaining mechanism, a low gear shifting means, and a transmission mechanism. The support means is fastened with the handlebar of a bicycle. The low gear shifting means has a low turning rod connected with the support means by a first retrieving spring and provided with a first braking portion. The cable winding means is connected with the support means by a torsion spring. The fixation plate is provided with a second braking portion. The high gear shifting means has a high turning rod fastened with the fixation plate by a second retrieving spring. The retaining mechanism has a shaft fastened pivotally with the support means and the fixation plate. The shaft is provided with an engaging means and a first cam, a first ratchet portion and a third braking portion.

  • Patent number: 5673594
    Abstract: The present invention relates to a bicycle speed change lever apparatus which is mounted near the handlebar of a bicycle. A lever apparatus is used for pushing a ratchet member, allowing the ratchet member to produce a positive or negative rotation, which further drives a cable-pulling member, thus allowing the cable to be tightened or relaxed by the cable-pulling member to accomplish an in or back shift. A position maintaining mechanism is also provided for effectuating the shift change, and the cable is allowed to maintain a certain amount of tension. The speed change lever apparatus eases the shifting operation and makes the in shift or back shift more precisely controlled.

  • Patent number: 5632226
    Abstract: A speed indicator for bicycles for indicating the shifting action of the bicycle and a speed sign at each state of shift includes a driving wheel driven by a takeup reel of a shifting device, a resilient strip driven by the driving wheel, and a track along which the resilient strip may displace. When the resilient strip displaces along the track, a shift sign pre-formed on the resilient strip may be shown through an indicating element provided on the track. The resilient strip may be adapted for use in vertically or horizontally oriented tracks of any construction, and their assembly is easy. The driving wheel further includes a compensation mechanism for ensuring clear indication of the indicated sign on the resilient strip.
