The present invention concerns the field of garments, namely the shoes sector, especially relating to children, although it is likewise applicable to young people and adults. The object of the present invention is an outer sole (1), on which are inserted two structures, a first one enabling one user to slide when he is contacting the ground, moving as if he were on skates, and a second one enabling the user to move in a conventional way. The first structure, which enables a movement in a rolling mode, consists in a frame (2) containing a wheel (3) and, on one end, presents a front locking member (4) and, on another end, a locking member (5) for disengagement of the frame (2) by pressing downwards.

The present steerable wheel assembly incorporates a lean-to-steer mechanism into an inner race of a roller bearing, while a wheel is mounted to an outer race of the roller bearing. A shaft extending from the mechanism is attached to a body, and the mechanism acts to steer the outer race and the wheel about a vertical steering axis when the shaft is tilted about a horizontal axis. The mechanism can be a pivot joint, providing a linear steering response, or can be a lean-to-steer mechanism that provides a non-linear response where the steering action is not proportionally responsive to tilting over the expected range of tilting.

A motorized vehicle assembly includes an axle comprising a channel extending along a central axis of the axle, a socket positioned within the channel of the axle, and a motorized wheel configured to be mounted on an end the axle. The motorized wheel includes a boss configured to engage the end of the axle when the motorized wheel is mounted on the axle, an electric motor, a tire mounted on the rotor, and a plug positioned within the boss, the plug configured to engage with the socket when the motorized wheel is mounted on the axle. The electric motor includes a stator fixed to the boss and a rotor surrounding the stator, the rotor configured to rotate relative to the stator. The electric motor is configured to cause the rotor to rotate relative to the stator to cause the tire to rotate.

An electric weight sensing skateboard using one or more strain gauge systems to detect rider-induced strain on one or both trucks, an inertial sensor to detect accelerations and balance position, and wheel speed sensors. Throttle is controlled by rider position, for example, lean forward to increase speed, lean back to slow down. Several drive methods include a driver position detection velocity setpoint control, torque setpoint control, and direct velocity/torque control. A throttle remote is note required. Rider weight activates the motors.

An aluminum or aluminum alloy wheel hub having at least one display opening for electrically operated display device and at least one interior channel anodized to a sufficient electrically insulative thickness, the channel is dimensioned to receive at least one electrically conductive element of a compact generator. The display device can be a LED device. The wheel hub is especially suited for roller skate, in-line skate, and skate board wheels.

A wide wheel inline roller skate has a boot, a chassis, and a plurality of wheels. The boot is removably attached atop the chassis, and the plurality of wheels is rotatably connected to the chassis opposite the boot. Each of the plurality of wheels is bi-directionally tapered from a medial diameter outward to a lateral diameter, wherein the medial diameter is larger than the lateral diameter. Thus, the wide wheel inline roller skate affords greatly increased surface area contact between a supporting ground surface and any given wheel, thereby increasing stability and safety, compared to conventional in-line roller skates, particularly while turning.

The mechanism can be a pivot joint, providing a linear steering response, or can be a lean-to-steer mechanism that provides a non-linear response where the steering action is not consistently responsive to tilting over the expected range of tilting. The present non-linear lean-to-steer mechanisms can also be incorporated into alternative lean-to-steer devices, and alternative mechanisms can employ tracking structures to coordinate tilting motion of a first moving element with steering motion of a second moving element to provide a non-linear lean-to-steer response.

A multi-link wheel base includes a main body composed of a plurality of links connected in series and wheels provided on the main body, and the wheels are provided on the link assembly the link assembly includes an intermediate link and an end link, wherein both sides of the intermediate link are provided with a rotational connection position, one side of the end link is provided with a rotational connection position, and the rotational connection positions on the adjacent link assemblies are rotationally connected by means of a connecting device.

A caster board can include a front platform, a rear platform, and at least two neck sections extending between the front platform and the rear platform. The neck sections can serve as a torsion element allowing twisting of the front platform relative to the rear platform. An aperture between the neck sections can be configured to receive an insert. The insert can alter a structural characteristic of the caster board, such as the torsional stiffness of the caster board.
