Abstract:
1. An apparatus for controlling the rotational speed of a wheel supported by an axle of a wheeled device in the form of a skateboard or roller skate, said apparatus for controlling the rotational speed of the wheel during use of the wheeled device and comprising, in combination: a lug adapter connected to the axle, said lug adapter projecting outwardly from the axle and away from the wheel rotatable about said axle, said wheel having a wheel face; a wheel contact member rotatably mounted on said lug adapter for engaging said wheel face and rotating with said wheel; a wheel contact member engagement structure mounted on said lug adapter for applying a frictional force to said wheel contact member resisting rotational movement of said wheel contact member and said wheel when said wheel contact member engages said wheel; and a manually operable control structure in operative association with said wheel contact member engagement structure to selectively vary the magnitude of the frictional force applied to said wheel contact member by said wheel contact member engagement structure, said manually operable control structure including a hand knob assembly manually movable relative to said lug adapter and relative to said wheel contact member to selectively either increase or decrease the magnitude of frictional force applied to said wheel contact member by said wheel contact member engagement structure, said hand knob assembly including a rotatable hand knob threadedly engaged with said lug adapter and rotatable relative to said lug adapter about an axis of rotation concentric with the longitudinal axis of said lug adapter and wherein said apparatus includes a dial housing connected to said lug adapter and fixed against rotation relative to said lug adapter, and rotation of said rotatable hand knob in a predetermined direction being operable to move said dial housing along said lug adapter in the direction of said wheel contact member, said dial housing and said wheel contact member defining an interior space therebetween.
