An ice skate for skating on ice, which comprises; an upper chassis section comprising a first contact surface having a front end and a rear end, a lower chassis section comprising a second contact surface having a front end and a rear end, and a coupling arrangement comprising a spring back means, which coupling arrangement is arranged to mechanically connect the upper and lower chassis sections.

A self-propelled, one-wheeled vehicle may include a suspension system configured to dampen up and down motion of a board relative to the axle of a central wheel assembly when the vehicle encounters obstacles and bumps on a riding surface. Illustrative suspension systems include a shock absorber, a rocker, a pushrod, bell cranks, and/or a swingarm that couple the axle to the board. The suspension system may be disposed completely below a foot deck of the vehicle.

According to an aspect of some embodiments of the present invention there is provided a driving unit for an in-line skate system having roller wheels, the driving unit has a motor configured to generate a driving power, a transmission gear coupled to the motor, and a transmission belt interconnecting the transmission gear and the two or more roller wheels to transfer the driving power to the roller wheel. According to an aspect of some embodiments of the present invention there is provided an in-line skate system, comprising one or more in-line skates and a driving unit.

A personal transport includes a deck configured for supporting a rider in a standing position. At least one wheel assembly is mounted on a bottom surface of the deck, the, or each, wheel assembly having at least one wheel so that the deck can travel over a substrate. An operator handle is substantially rigidly mounted on a rear end of the deck and extends rearwardly from the deck so that an operator, standing on the substrate, can grasp the operator handle and push the apparatus along the substrate, or tilt the apparatus relative to the substrate, while the rider is supported on the deck. A rider handle mounted on one of the deck and the operator handle and positioned so that the rider can grasp the rider handle for balance while supported by the deck.

A skate blade has a tube (1) featuring a complex radiused slot (5) in which the runner (3) is placed, thereby imparting the complex radius to the runner (3). A uniform quick mounting structure is also provided, whereby a mounting cup (8) attached to the tube (1) is secured to a skate boot by interaction between a retention jib (11) and a mounting plate (10) that is located on the boot. This provides a uniform and repeatable attachment. Other features include harmonic dampening, adhesive retention features, boot alignment features.

A stowable motorized skateboard comprising a first board section, a second board section, a power supply section, and support bars. The first board section includes a locking mechanism and first support anchors. The second board section includes a controller, a motor, second support anchors, and power supply anchors. The power supply section is between the first and second board sections, encasing a battery electrically coupled to the controller and the motor, and including a catch receiving the locking mechanism. The power supply section further receives the power supply anchors. The support bars extend from the first board section to the second board section and receive the first support anchors and the second support anchors.

A roller blade ice wheel assembly for using roller blades on ice includes a plurality of blade wheel apparatuses each comprising a wheel body having a central wheel aperture, a pair of wheel sidewalls, and a wheel edge. The wheel edge is less than 0.5 cm. At least one bearing is coupled to the wheel body. The bearing receives an axle of a roller blade through a bearing aperture and the wheel aperture. Each of a plurality of spacers has a central spacer aperture to receive the axle of the roller blade. The plurality of spacers is positioned on both sides of the bearing to occupy space up to a wheel frame of the roller blade. The width of the blade wheel apparatus is dimensioned to equal the width of a wheel of the roller blade that is being replaced.

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.

A multi-degree of freedom ice skate post that connects an ice skate blade to the sole of an ice-skating boot generally comprises a plurality of adjustable elements that include a pronate/supinate platform, a bi-directional module and a side/side module. In some configurations, the pronate/supinate platform is configured to move the ice skate blade in a pronate and supinate direction. In some configurations the pronate supinate platform is connected with the bi-directional module providing movement of the ice skate blade in the fore and aft position. In some configurations the side/side module is connected with the bi-directional module providing movement in a side by side direction. Additional configurations can include vertical adjustments as well.

A steering axle unit (24) for chassis or skateboards, comprising a bearing block (1) and a steering axle body (98), wherein the bearing block (1) has a fastening plane (11) for fastening to a chassis or skateboard, particularly skateboard deck (52), wherein, in the assembled state, the fastening plane (11) is arranged on the chassis or skateboard particularly so as to be parallel to the designated direction of travel (25) of the chassis or skateboard, and wherein the bearing block (1) comprises a vertical axis CD (22) about which the steering axle unit (98) is arranged so as to rotate relative to the bearing block (1), an axle (8) that projects normally from the vertical median longitudinal plane of the bearing block (1) in the straight-ahead position being arranged on the steering axle body (98), wherein the vertical axis CD (22) is arranged on the median longitudinal plane of the bearing block (1) at an angle W1 (19) of less than 90° relative to the fastening plane (11) in the direction of the steering axle body (98), wherein the axle (8) is arranged at a normal distance (20) to the vertical axis CD (22), and wherein the axle (8) is arranged in front of the vertical axis CD (22) in the designated direction of travel (25) of the chassis or skateboard.
