20160052337 | ANTI-SLIP DEVICE FOR A HUB OF A BICYCLE - An anti-slip device for a hub of a bicycle is provided for a first engaging element and a second engaging element between a bicycle hub and a chain wheel drive seat of the bicycle. A second engaging element has one side facing the chain wheel drive seat and including indentations equally defined therein. Each indentation has a bottom and a protrusion extending from one end of the bottom, wherein protrusion has a shoulder and a distal end. The chain wheel drive seat has multiple curved control blocks laterally extending therefrom, wherein the multiple curved control blocks are annularly arranged. Each curved control block is movably received in a corresponding one of the indentations and a circle difference is formed between the corresponded curved control block and the indentation. | 02-25-2016 |
20130175122 | HUB BRAKE FOR A BICYCLE - A hub brake for a bicycle mainly comprises a fixed brake disc, axial displacement brake disc and brake member. The axial displacement brake disc is driven by the brake member to yield axial displacement, thus realizing axial hub braking through frictional abutting of the fixed brake disc. As the fixed brake and axial displacement brake disc are both of simplified disc or block structure, the manufacturing process can be streamlined for mass production, while convenient and efficient assembly from one end of the hub is made possible. As for the ringed brake interface formed between the fixed brake disc and axial displacement brake disc, its friction area is not less than that of conventional drum or caliper brake interface. Hence, the hub brake components of the bicycle could be greatly simplified, and the weight and assembly space could be reduced for easier production, convenient assembly and satisfactory braking performance. | 07-11-2013 |
20120152682 | ONE-WAY RATCHET UNIT FOR A BICYCLE WHEEL - A one-way ratchet unit for a bicycle wheel has first and second meshing parts and an elastic member. The meshing parts are respectively configured on the bicycle wheel and the sprocket driving seat, their first and second one-way ratchets both comprise ratchet tips, ratchet roots and oblique guiding facets. The ratchet tips of the first or second one-way ratchet are configured with at least one wedge on partial positions, and the positions on the ratchet tips of the first or second one-way ratchet not forming the wedges form convex resisting edges. The ratchet roots of the second or first one-way ratchet are configured with wedge avoiding parts on partial positions, so that when the first and second one-way ratchets mesh each other and the resisting edges of the ratchet tips resist against the ratchet roots, said ratchet tips can be aligned and go into the wedge avoiding parts. | 06-21-2012 |
