    摘要: A rolling kneepad having a weight transfer support assembly with swivel casters to support a user, a kneepad cushion provided above the support assembly to comfortably receive a user's knee, and a shin guard peripherally attached to the support assembly and extending outwardly therefrom. The elongated shin guard has a distal end which abuts the upper surface of a user's shoe or boot. Consequently, when the user moves from a kneeling to a standing position, the weight of the rolling kneepad is supported on the top surface of the user's shoe or boot. Downward slippage of the rolling kneepad along the user's leg is prevented and manual reposition of the rolling kneepad prior to the user resuming a kneeling position is avoided. Straps having hook and loop fasteners at the ends are typically used to affix the rolling kneepad to the body of the user.

    摘要: A bottom bracket assembly for bicycle frames aligns crankshaft bearings. The assembly is press fitted into the bottom bracket shell to journal the crankshaft. An elongated, rigid, unibody sleeve comprises a terminal end and a spaced apart leading end which both receive and support a radial contact bearing that is press fitted into a machined bore. Each bore comprises an interference fit zone for bearing retention and a larger, pressure relief zone comprising a channel and an adjacent, buffering slope that compensates for stresses. Dust shields coaxially abut the bearing exteriors. An inner, tubular buttress bushing coaxially occupies the sleeve interior and extends between the spaced apart bearings to brace them. Externally the sleeve has a pair of integral, friction retention contact interfaces separated by a reduced diameter optimization zone. The sleeve terminal end has an integral stop flange that abuts the frame bottom bracket shell contacting the crank arm.
