Abstract:
An expandable shaft assembly including an axially extending shaft with an axial axis, an extending shaft with an axial axis, an external dimension, at least one shaft end and a bore extending generally axially from the at least one shaft end. The shaft assembly also includes a second element, as an axle cap, with an axially extending, externally threaded portion with a first thread flank, a shoulder portion extending in a generally radially outwardly direction. A radially extending end face is also provided that is axially constrained relative to the shaft, wherein the radially extending end face is one of (1) integral with the shaft, and (2) on a separate element. The bore of the shaft includes an axially extending, internally threaded portion with a second thread flank, wherein at least one of the first and second thread flanks are inclined. The externally threaded portion of the second element is threadably engaged with the internally threaded portion of the shaft such that the first thread flank contacts the second thread flank. In addition, the shoulder portion of the second element is pressed against the end face and the inclined thread flank is wedged against at least one of the first thread flank and second thread flank to provide radial expansion of the external dimension in an expansion region.
Abstract:
A vehicle wheel spoke termination assembly includes an outer rim with means for holding a tire, a central hub assembly and a plurality of spoke portions. The central hub assembly includes an axle assembly and a hub shell that is rotatable about the axle. The spokes are connected at their outer ends to the outer rim hoop and at their inner ends to the hub flange. A connecting element is blindly attached to at least one of the outer rim and the hub flange for a firm connection between the connecting element and the spoke.
Abstract:
Improved vehicle wheel construction with a peripheral rim, a central wheel hub and a plurality of spokes extending between the rim and hub, wherein the spokes have a first peripheral portion connected to the rim and a second central portion opposed to the first portion. The hub includes at least two opposed outer flanges, with the central portions of the spokes secured to at least one of the outer flanges by hardened molding material.
Abstract:
A power transmission element including an improved drive sprocket assembly with at least one preformed sprocket and a central sprocket carrier, wherein the sprocket teeth of the sprocket extend beyond the central sprocket carrier for mating with a roller chain, and wherein the sprocket is secured to the sprocket carrier via deformation of the sprocket carrier.
Abstract:
The present invention relates to the attachment of a rear bicycle wheel to the bicycle frame and involves a decoupling engagement mechanism between the one-way clutch assembly of the freehub, commonly referred to as the freehub body, and the rear hub shell.
Abstract:
Clamping device for clamping a shaft to a base member including a base member, at least one clamping element spaced from the base member, a shaft having a longitudinal axis and extending along the base member between the base member and clamping element, connecting links connecting the clamping element to the base member, and a bolt for moving the clamping element into locking engagement with the shaft exerting a clamping action on the shaft which is parallel to the shaft.
Abstract:
A bicycle chain hanger comprises a unitary member molded from a polymeric material and including a disc-like base portion having a concavely curved internal surface adapted to bear against the wall of the seat stay and a generally L-shaped hook portion extending outwardly from the base portion and adapted to accept and hold an element of the chain in hooked relation. Two pins, driven with a force fit through each of two holes and through corresponding split sleeves that extend through holes in the seat stay tube into the space within the tube walls, deflect portions of the split sleeve out into interfering relation with the walls and edges of the tube holes and thereby retain the member on the seat stay.
Abstract:
A cable guide for affixing a cable or the like to a tube of a bicycle frame comprises a body including at least one base portion adapted to seat on the frame member and having at least one hole, a ferrule portion extending up from the base portion and adapted to receive the cable, and a split sleeve portion extending down from the base portion in alignment with the hole and adapted to extend through a hole in the frame tube. A mandrel is received through the hole in the base portion, extends through the split sleeve and expands the legs of the sleeve outwardly into tight engagement with the wall of the hole in the tube and expands the ends of the sleeve outwardly within the tube, whereby the expanded and extended split sleeve retains the guide on the frame tube.
Abstract:
A flex screen having: a width; a length; a thickness; a plurality of openings having a length and width, with a first opening laterally adjacent a second opening and longitudinally adjacent a third opening; a plurality of stringers, including a first stringer laterally positioned between the first and second openings; and a bridge between the first and third openings. The first opening is laterally bounded between the first and second stringers and longitudinally bounded by the bridge, which serves to span and connect the first and second stringers. The first opening is longitudinally staggered from the second opening and the bridge is connected to the first stringer at a location longitudinally partway along the second opening. The flex screen may be elastically flexed to a flexed orientation, including torsional displacement of the first and second stringers. The lateral width of the first opening is greater than the thickness of one of the first and second stringers.
