  • Patent number: 5385360
    Abstract: Locking the headset of a steering post of a bicycle is accomplished by this invention where the steering post or threaded body projects coaxially through a cylindrical journal mounted at the front end of the bicycle frame. Bearing cups are secured in each end of the journal to accommodate thrust bearings. Each thrust bearing in turn is engaged by a cone. The lower cone is mounted stationary on the fork-steering post of the bicycle while the upper cone is threaded engaged to the mounting post body and is drawn hand tight against the upper thrust bearing. The upper cone is locked against rotational movement by a lock nut threaded on the post body above the upper cone and spaced from the upper cone. The locking configuration is achieved by one or more screws extending through an opening in the lock nut and engaging the upper cone to jam the threaded connections between the lock nut, upper cone and steering post body.

  • Patent number: 5048358
    Abstract: A rotary phased radial thrust variable drive transmission which is lcoated between an input driving member, such as the pedal-driven sprocket of a bicycle, and an output driven member, such as the hub of a bicycle wheel which are mounted for relative rotation on a common axis, such as the axle of the rear wheel of a bicycle. The transmisison includes radial thrust linkages which are carried by the input driving member for cooperating with a surrounding cam ring assembly having a normally fixed cam profile providing a torsional thrust on the output driven member to cause rotation thereof. The cam ring assembly is selectively adjustable to vary its profile.

  • Patent number: 4995753
    Abstract: A clamping means for clamping the wires of a saddle to the upper end of a support post of a bicycle frame or the like. It consists of a lower cradle support clamping member and a cooperating upper clamping member which are mounted on the post to permit tilting of the saddle. The clamping members are so designed that they can be extruded from metal with a post-receiving socket at the lower side of the lower member. This socket, because the lower member is extruded, has a flat inner wall and side walls extending linearly in spaced relationship, with the side walls being at sharp angles to the inner flat wall to provide sharp corners for engaging the sides of the post at a fulcrum formed thereon to prevent lateral displacement of the lower cradle support on the post.

  • Patent number: 4850733
    Abstract: An expander for a bicycle seat support post inserted into a tubular socket of the bicycle frame. The post has an expandable collar which is expanded by means of a wedge-like expanding member which projects from the collar and which is moved axially thereinto by means of a tension link. Movement of the link to pull the wedge-like member farther into the collar is accomplished by a screw angularly supported on the post at an angle of less than ninety degrees to its axis.

  • Patent number: 4437596
    Abstract: A wire bottle cage, which has an insert open end and a closed or stop end with a back formed of laterally-spaced longitudinally-extending wires with a bumper and guide at the front and a catch and guide at the back which serve to cause the corner, at the bottom of the bottle, to slide along the back wires as it is inserted into or removed from the cage, along with special mounting means to attach the cage to a cycle bar or similar support in such a manner as not to interfere with the sliding action of the bottle on the back wires and to positively lock the cage in place on the bar.

  • Patent number: 4009810
    Abstract: A cage for receiving and holding a water bottle which can be readily attached to a bicycle frame or the like. It consists of a single piece of resilient wire bent to form the cage with a solderless, weldfree connection for the joint at the adjacent ends of the wire. This connection, along with a special mounting means, also provides a less abrasive protective surface for frictionally engaging and gripping the bottle.

  • Patent number: 3933391
    Abstract: A bicycle seat mount for mounting the usual saddle seat including a special post and cooperating clamping bracket. The clamping bracket is adjustable to releasably clamp the wires of the saddle seat to permit forward and rearward adjustment and is attached to the post for vertical pivotal movement about the transversely disposed apex of an angular support surface provided at the upper end of the post.
