20060019781 - Continuously variable belt drive system: A belt-type continuously variable transfer system (15) includes a driving pulley assembly (20), a driven pulley assembly (22) and a V-shaped belt (24) engaged to transfer rotary power therebetween. The driven pulley assembly (22) can include a ratio adjustment mechanism (46) that adjusts the position of a rear sheave (40)...

20060019782 - Front derailleur and chain guide: A front derailleur including a chain guide for engagement and disengagement of a bicycle chain with multiple chain rings of a crankset is disclosed. The chain guide may be positioned by linear guide rods. The chain guide may have an inner lifting surface and an outer pulling surface for engaging...

20060019783 - Deckless treadmill system: A deckless treadmill system comprising a cogged-belt in combination with elongated and complementary cogged drive rollers and a series of aligned and cooperatively interactive cogged support rollers disposed proximate to and in cooperative engagement with the peripheral underside edges of the cogged belt. Accordingly, the structural configuration and mechanical componentry...

20060014599 - Sprocket-carrying body for the rear wheel of a bicycle: A sprocket-carrying body for a rear wheel of a bicycle has a tubular body, suitable for externally receiving a plurality of sprockets, a plurality of ribs at an outer surface of the tubular body, the ribs extending in a substantially axial direction between a first end portion of the tubular...

20060014600 - Lightweight drive chain: A lightweight drive chain includes a plurality of parallel pairs of outer chain plates and a plurality of parallel pairs of inner chain plates. Each of the outer chain plates further has a pair of first weight-reducing slots, each of which extends radially from a first hole periphery of a...

20060009321 - Hybrid clamping mechanism for belt continuously variable transmission and method of use thereof: A hybrid clamping mechanism for a belt continuously variable transmission (CVT) is disclosed. A pulley having adjustable belt-engagement surfaces allow for a variable effective diameter of the belt when about the pulley. A clamping spring disposed to bias the belt-engagement surfaces closer together exert a clamping force on the belt....

20060009322 - Belt installation tool: A belt installation tool having a body and an angular member projecting from the body for engaging a pulley belt bearing surface. A surface disposed substantially normal to the angular member comprises a chamfered lip for engaging a pulley web feature. The lip and angular member removeably attach the tool...
