Abstract: A bicycle damping system is arranged to reduce vibrations that originate at the bicycle wheel and are transmitted to the rider of the bicycle. Desirably, a front fork assembly is configured to be supported by a bicycle frame and includes a pair of fork legs, which extend in a downward direction along opposing sides of a front wheel of the bicycle. Preferably, the fork legs are configured to support the front wheel at their lower ends. Each of the fork legs can define a cavity and a damping member is positioned within the cavity. The damping member can be forced into contact with a surface of the fork leg. Seat stays, chain stays, the seat post and other components of the bicycle can also include a damping system.

Abstract: A construction vehicle includes first and second track assemblies. The track assemblies each include an inner portion, and outer portion and a middle portion between the inner portion and the outer portion. An adjustment mechanism is pivotably coupled to the middle portions of the first and second track assemblies. The adjustment mechanism extends and retracts along a width axis to adjust a distance between the first and second track assemblies. The width of the first and second track assemblies can determine an overall width of the construction vehicle.

Abstract: A mounting assembly for attaching auxiliary equipment to a wheelchair includes multiple adjustment features. In the preferred embodiment, different wheelchair widths may be accommodated by utilizing attachment arms that pivot co-axially with a main column of the auxiliary equipment. The mounting assembly preferably includes a pair of arms and a pair of links that extend from the arms. The lengths of the links and the arms may be adjusted by rotation of a rod portion of each arm and each link, but other means for enabling changes in length are possible. The links are preferably pivotally connected to the arms, so that the distance between the ends can be varied on the basis of the particular wheelchair. Ball-and-socket joints are used, but rotatability of the sockets permits flexibility of the orientations of the joints. Additionally, a vernier adjustment effect may be included to permit adjustments in the angle of the main column.
