The invention comprises a truck and riding devices with a lean steering spatial mechanism comprised of rigid bodies and a single compliant body connected by joints forming a closed kinematic chain wherein the compliant body provides compression, tension, and torsional return spring forces for multi-axial functionality within the constraints of the lean steering spatial mechanism, allowing for the combined functionality of deep deck lean, improved lean steering control over a wider range of speed, improved speed stability, and full load bearing suspension. The invention has additional degrees of freedom and additional primary motions of floating and suspension.

Lean steering spatial mechanism for a riding device

A truck with two rigid bodies and an elastomeric component wherein a front truck and a rear truck may be connected with a frame to comprise a riding device with a longitudinal roll axis coincident with a virtual line between a front virtual pivot point and a rear virtual pivot point. Each virtual pivot point is located at the intersection of a line projecting upward from the central point of a hanger axle axis and a hanger pivot axis. Virtual pivot points are the points about which the front and rear hanger pivot axis rotate as a result of rider input leaning to the right or left.

The present invention comprises structural fenders for a riding device with laterally-spaced wheels, for example on a skateboard. Each wheel is covered by a structural fender that supports the wheel axle on each side of the wheel. Each wheel may have its own axle, or a pair of laterally-spaced wheels may have a single axle. The structural fenders may be used with a skateboard, scooter, or other riding device, and may be connected with a truck hanger comprised of three rigid bodies connected by revolute and spherical joints and a single compliant body to provide three primary motions: leaning, steering, and floating.

Each virtual pivot point is located at the intersection of a line projecting upward from the central point of a hanger axle axis and a hanger pivot axis. Virtual pivot points are the points about which the front and rear hanger pivot axis rotate as a result of rider input leaning to the right or left.

A truck for a riding device with three primary motions of leaning, steering, and floating, comprising three rigid bodies, a baseplate, a revolute floating kingpin, and a hanger. A revolute joint moveably connects the kingpin and baseplate, an upper spherical joint moveably connects the baseplate and hanger, and a lower spherical joint moveably connects the hanger and kingpin. The upper and lower spherical joints define a hanger pivot axis, with a virtual pivot point at the intersection of the hanger pivot axis and a line vertically projected from the axle axis. A longitudinal roll axis is coincident with the axis of rotation of the revolute joint. In a riding device, a virtual pivot point roll axis is coincident with a virtual line between a virtual pivot point of the front truck and a virtual pivot point of the rear truck.

A wheel-bearing truck as might be used on a skateboard includes a base, a transverse hanger mounted pivotally at or near its center to the base and adapted to bear a road-engaging wheel at each opposed end. There is a pair of telescopic arms, one end of each being attached to the hanger flanking its center. A longitudinal spring fixed with respect to the base interacts with the other end of each telescopic arm.

Wheel-bearing truck

A truck and a skateboard assembly comprised of two trucks and a deck. The truck of the present invention has three rigid bodies and two degrees of freedom. The three rigid bodies comprise: (1) the deck and baseplate assembly for the skateboard assembly, or the baseplate assembly for the truck; (2) the hanger assembly; and (3) the floating kingpin assembly. The three rigid bodies are joined together by three spherical joints and elastomerically coupled and constrained by elastomeric components. The truck of the present invention provides the combined functionality of deep deck lean, improved steering control over a wider range of speed, improved speed stability, and improved suspension compared to existing skateboard trucks.

Skateboard assembly and truck assembly with floating kingpin

A compact lean steering truck assembly that provides deep deck lean capability. The lean steering truck assembly may be integrated into a four wheeled scooter. A pivotal coupling in the front hanger allows independent steering of the front and rear wheel assemblies. Front steering is controlled by the rider's hands twisting the handle bars to the right or left or straight ahead. Rear steering is controlled by the rider's feet and hands leaning the deck and handle bars relative to the plane of the ground. The ratio of deck lean to rear steering is a function of the hanger pivot axis angle but in general terms the deeper the deck lean the greater the rear wheel steering.

Rear truck and method

A lacrosse head includes a socket, a base region adjacent to the socket, and a pair of sidewalls extending from the base region to a scoop. A lower rail of each sidewall includes an open channel that is visible from an exterior of the lacrosse head. Multiple support ribs are located in each of the channels and extend from a first wall of the channel to a second wall of the channel. A ball stop extends between the sidewalls adjacent to the base region. A flexible cartridge optionally is positioned between the ball stop and the socket. The support ribs provide increased stiffness near the joint between the ball stop and the socket.

A mechanical assembly which enables multi-track vehicles to lean into turns and return to a neutral position thereafter.

A riding device includes a deck upon which a rider can be supported. Front and rear road wheels provide independent steering upon tilting or banking of the deck in use. A steering column is connected to the front wheels to provided additional steering control. The steering column tilts in unison with the deck and provides no steering effect upon deck pivoting alone.
