  • Patent number: 7635170
    Abstract: A spoked wheel comprises a rim, a hub, V-shaped spokes, nipples, and eyelets. There is true pairing of the spokes, because the rim has half the number of spoke attachments as there are nipples. True paired spoking means that there are no side wobble forces or rim twist caused by spoke tension. The rim has spoke attachment holes that are parallel to the axis of wheel rotation and are reinforced with eyelets. The rim has unnecessary material cut away between the spoke attachment holes. To ease adjustment, the nipples are located about midway between the hub and the rim. The hub has longitudinal ribs and that are aligned with each other. That allows the hub body to be machined from a relatively lightweight extrusion. To increase the wheel strength, the inboard spokes are moved outboard as much as possible. The hub has pairs of nipple attachment holes where each pair is located on a diagonal relative to the axis of the hub.

The wheel further comprises locking means of the spoke with respect to the hub adapted to prevent or to limit a displacement of the abutment surface away from the first stop surface in a detensioning condition of the spoke, as in, for example, that which occurs for a violent impact against uneven or rough ground.

  • Patent number: 7374251
    Abstract: A bicycle hub has an axle and a hub shell rotatably disposed about the axle with a plurality of spoke fixing parts disposed at opposite ends of the hub shell. Each of the spoke fixing parts has a through hole having a small width section extending from a first side of a corresponding one of the spoke fixing parts and a large width section extending from a second side of the corresponding one of the spoke fixing parts such that an internal abutment is formed between the small and large width sections. The securing elements are removably disposed in the large width sections of the spoke fixing parts of the hub shell with each of the securing elements having a threaded bore that is aligned with and substantially equal to the small width sections of the spoke fixing parts of the hub shell.

  • Patent number: 7354114
    Abstract: A spoke for a bicycle wheel has an elongated metallic material body that extends along a longitudinal axis X-X and has a first end portion for the attachment to a hub of a bicycle wheel, a second end portion for the attachment to a rim of a bicycle wheel and an intermediate portion having a portion which is flattened in a transversal direction Z perpendicular to the longitudinal axis X-X and extending along the longitudinal axis X-X up to the first end portion. The first end portion of the spoke is also flattened in the transversal direction Z and is gradually joined to the flattened portion of the intermediate portion along the longitudinal axis X-X.

  • Patent number: 7181844
    Abstract: A method for increasing structural strength of spokes of a bicycle or a motorcycle, which adopts a mechanically processing measure to increase the structural strength of the bending section of the spoke. The spoke is many times compressed to process and harden the bending section of the spoke so as to enhance the metal strength (shearing strength) of the bending section. At the same time, the wire diameter of the spoke (cross-sectional area) is increased due to compression in accordance with the principle that shearing load=shearing strength×cross-sectional area. With least metal material and lower processing cost, the spoke can have highest structural strength.

  • Patent number: 7140694
    Abstract: A Wheel Spoke Adjuster Guard that comprises a visually pleasing outer shape with an internal cavity, where the internal cavity has a lower portion shaped complimentary to the wheel adjuster nuts on the wheel spokes of either motorcycles, bicycles, or other motor conveyances using spoked wheels and an internally threaded portion adapted to threadably engage the spokes of the wheel. The upper portion of the internal cavity has a shape complimentary to the existing diameters of the spokes of the wheel assemblies. The adjuster guard is threaded onto the spoke and the internal cavity encases the spoke adjuster. The adjuster guard may have some Lock-Tite© or sealant to prevent any loosening of the adjuster guard.

  • Patent number: 7137671
    Abstract: An element for the attachment of a spoke in a bicycle wheel at a seat hole has a body, an axial hole, and can engage a tool. The body is of greater transverse size than a seat hole, and abuts the seat hole at a first end of the body. The axial hole extends from the first end in the body and engages a spoke. The element engages a tool at a second end of the body opposite the first end. Finally, the maximum transverse size of said body is defined by side surface portions of said body other than the area of the second end that engages the tool.

  • Patent number: 7093910
    Abstract: A bicycle rim includes a plurality of recesses defined in an inner periphery thereof and a through hole is defined through the rim and shares a common axis with the recess corresponding thereto. A plurality of spokes each have a threaded hole defined in a first end thereof which is fitted in one of the recesses and a plurality of bolts extend through the through holes and are threadedly connected to the threaded holes in the spokes. The through holes are small so that they do not reduce the structural strength of the rim and the end of each spoke is fitted in the recess to further position the spokes to the rim. A second end of each of the spokes is connected to a hub by extending a bolt through the hub and threadedly connected to the second end of each spoke.

  • Patent number: RE39781
    Abstract: A magnetic device mounts on a flat spoke of a wheel. This magnetic device can comprise a magnet and a housing. The housing is coupled to the magnet, and has a spoke-receiving recess with a non-circular cross section, and at least one detent. The detent extends from the housing into the spoke-receiving recess to secure a flat spoke within the spoke-receiving recess via a snap-fit. The magnetic device communicates with a sensing device, which is adapted to be coupled to a portion of the bicycle that is adjacent to a wheel of the bicycle. A display unit, adapted to be mounted on handlebars of the bicycle, displays the speed information obtained from the sensing device. In a second embodiment, the housing is made of a more elastic material, and the detents become optional. In a third embodiment, the spoke-receiving recess of the housing has a projection that engages a concavity form in the connecting portion of the spoke.
