A skate includes an inverted groove-shaped base secured to a boot and including front and rear pins; an elongated frame including front and rear sets of a transverse inner groove and a transverse open groove communicating with the transverse inner groove, and a threaded hole on the transverse open groove of the front set wherein either pin is disposed in the transverse inner groove and the elongated frame abuts an underside of the base; and a locking device including a spring biased block member disposed in the transverse open groove of the front set and having two projections at two ends respectively, a screw driven through a positioning member into the threaded hole to fasten the positioning member in the transverse open groove of the front set so that the block member abuts the front pin to block same in an assembled state.

Disclosed is a bionic electric power-driven shoe, comprising a shoe sole (1), wherein a plurality of rotating wheels (2) are arranged below the shoe sole (1); an electric motor (3) is further provided at a lower part of the shoe sole (1); an output end of the electric motor (3) is connected to a transmission device in driving connection with the rotating wheels (2); and the shoe sole (1) comprises a heel part (11) and a sole part (12), the heel part (11) and the sole part (12) being in rotational connection.

Disclosed is an anti-reverse rotation device of a power-driven shoe device, the power-driven shoe device comprising a shoe sole (1), wherein a group of front wheels (2) and a group of rear wheels (3) are arranged on a lower side surface of the shoe sole (1); and the front wheels (2) are connected to an anti-reverse rotation mechanism for preventing the front wheels (2) from rotating in reverse. The anti-reverse rotation mechanism can prevent the front wheels (2) from rotating in reverse, and as such, when the front wheels (2) are independently in contact with the ground and a certain included angle is formed between a shoe body and the ground, the situation of the front wheels (2) applying a certain pressure to the ground and the front wheels (2) rotating in reverse, such that a lifted foot moves backwards, thereby causing a person to fall down, is avoided, and walking safety is improved.

A skateboard includes a board adapted for a user to stand with both feet thereon and having a major axis, and a front steering device and a rear steering device respectively disposed on front and rear sections of a bottom surface of the board along the major axis and each having two wheels. The front or rear steering device has a wheel seat disposed on the bottom surface of the board rotatably around a rotation axis which inclines downwards from front to rear, and a wheel rack disposed on the wheel seat rotatably or swingably around a main axis. An abutted surface is defined where the wheel seat and the wheel rack are abutted against each other. On an imaginary vertical plane including the major axis, where the rotation axis passes the abutted surface is in front of where the main axis passes the abutted surface.

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.

A quick-release truck system includes a deck plate, a truck plate, and a locking mechanism for releasably locking the truck plate to the deck plate. The deck plate mounts to an underside of a deck of a rideable vehicle, and the truck plate mounts to, or is integrated into, an upper surface of a truck baseplate. The deck plate and the truck plate slidingly engage one another using vertically-staggered complementary coupling means. The coupling means may further be horizontally-staggered to create a tiered configuration. The coupling means include a combination of rails and grooves. Once fully engaged, the truck plate releasably locks to the deck plate. The deck plate and the truck plate may include cut-outs for weight reduction.

A rotation powered vehicle drive mechanism includes an elongated chassis slot disposed within a respective lateral exterior portion of a chassis assembly. An elongated platform slot is disposed within a respective lateral portion of a platform assembly, and is configured such that it is substantially opposed to the chassis slot. The platform assembly is pivotally secured to the chassis assembly thereby allowing for rotation through a platform rotation angle of the platform assembly with respect to the chassis assembly about a rotation axis. The rotation of the platform assembly results in an increase or decrease of a variable slot height which is measured between the chassis slot and the platform slot. A cart assembly is disposed between the chassis assembly and the platform assembly, and is operatively coupled to the chassis slot and to the platform slot.
