Abstract: Provided is a rear wheel toe angle control system that can prevent the impairment of the tracking performance of the electric actuator and enable the rear wheel toe angle control system to ensure the stability of the vehicle even when the electric actuator for steering the rear wheel according to the operating condition of the vehicle is subjected to an axial force. An ECU (12) serving as a rear wheel toe angle control unit for variably controlling the rear wheel toe angle (?r) of the motor vehicle (V) by using an electric actuator (11) is provided with a duty ratio correcting unit (25) that corrects the target duty ratio (Dtgt) for achieving the target rear wheel toe angle (?rtgt) according to the load condition of the electric actuator (11) that depends on the lateral acceleration (Gy) of the motor vehicle (V).

Abstract: The present invention relates to a recreational and sporting device (10) comprising a foot support (12) that is mounted on a first wheel (26) such that the foot support is located below the axis of rotation of a first wheel (26). The foot cradle (12) is hingedly attached to a leg support (18) which is adapted to be attached to a user's leg. The device (10) may further include a second wheel (56) used for stabilization and to assist in steering. The device (10) provides a recreational and sporting apparatus that is more manoeuvrable and can be used on uneven terrain where conventional skates, such as in-line skates, cannot be used.

Abstract: A roller skate includes a fixing seat, a plurality of wheels, and a safety device mounted on the wheel. The safety device includes a safety member mounted on the fixing seat and urged on the wheel, so as to adjust a rotation speed of the wheel. Thus, the roller skate can be fixed on the ground without rotation by the safety device, so that the learner can stand on the roller skate without movement so as to practice his/her balance. In addition, the safety member is slightly loosened from the wheels, so that the wheels are rotated at a lower speed, thereby facilitating the learner practicing the skating skill.

Abstract: A braking assembly for use with a roller skate, the roller skate being wearable by an intended user having a leg, a foot extending from the leg and a hand. The roller skate has a frame, a foot receiving portion coupled to the frame for receiving the foot of the user and first and second wheels rotatably mounted to the frame, the first and second wheels defining respectively a first wheel radius and a second wheel radius. The first and second wheels further define respectively a first wheel circumferential surface and a second wheel circumferential surface.

Abstract: The three-wheeled skates system employs a conventional boot as used in in-line skates to which is attached a frame from toe to heel supporting a single wheel at the toe and a spaced pair of wheels sharing a common axle at the heel, the wheels being of the same type used in in-line skates. A mechanical braking system uses a handgrip lever controlling a brake actuator lever by Bowden-type sheath and cables. The brake actuator lever rotates about an axle, which applies the pressure of attached brakes for speed control. The rear axle is confined in generally frustroconical elastomeric elements and held within receiving bores within the heel portion of the frame, allowing the boot to lean inward relative to the wheels during a turn. The cant of the boot is adjustable from a cruising angle to a speed angle by settings of the front wheel on the toe frame.

Abstract: A brake handle, to be worn on a knee of a skater, for inline skate pull-cable brakes with a pull cable, has a brake handle body and an adjusting shaft arranged in the brake handle body. A pull cable is connected to the adjusting shaft. The adjusting shaft is employed to coil or uncoil the pull cable for shortening or extending the length of the pull cable so that the pull cable can be individually adjusted to the needs of the skater.

Abstract: A brake structure of a skateboard including: a casing having a cavity with an opening facing outward, the casing being fixedly disposed on an inner side of one end of the wheel shaft of the skateboard; two brake members pivotally connected in the cavity and movable between open and closed positions; a resilient member biasing the free ends of the brake members together; a rotary shaft having a driving section at one end, the rotary shaft being rotatably connected with the casing with the driving section positioned in the cavity, the free ends of the brake members touching two sides of the driving section; a rocking arm positioned on outer side of the casing and connected with the rotary shaft; a controlling assembly connected with the rocking arm; and a wheel disposed at one end of the rotary shaft. An annular wall projects from inner side of the wheel.

Abstract: A two-wheel high-speed glider inline roller skate having a boot with toe and heel pads to which a downward opening channel-shaped wheel support is attached centrally along the length of the boot. The channel structure has a front portion with sidewalls extending downward and forward of the boot toe to receive a front wheel between the sidewalls, the wheel mounted on an axle mounted to the channel structure by bearings. The channel structure has a rear portion that receives a rear wheel between its sides, the wheel being rotated on a rear axle and mounted to the channel structure by bearings. The rear wheel is located below the rear portion of the heel mounting plate. The rear portion has a hand brake system secured above the rear axle for acting on the rear wheel at its rear periphery.

Abstract: A turnable wheeled skate having first and second wheels. The first and second wheels may be located fore and aft of the foot receiving portion of the skate and one, the other or both may be turnable. Several embodiments are disclosed including, but not limited to, a skate that is turnable by tilting the skate perpendicular to a line-of-direction or that provides turnable, paired wheels or that receives a users foot at a level below the top of the first and second wheels. The skate may provide a skating experience that more closely approximates ice-skating.

Abstract: Improvements made to wheeled skate-skis with brakes usable on most terrains are: a hand controlled hydraulic fluid braking assembly, having a sole, resilient, curved spring, brake shoe, providing performance in comparison with the braking performance of a roadway motor vehicle; a chassis with a foot receiving body portion formed on a convex camber and made of materials which are flexible, under the weight of a person, thereby providing a spring like suspension, and with upwardly directed curved forked ends to position wheel axles higher above the ground to lower the foot receiving body portion, to thereby lower the center of gravity of the sportsperson, while moving on the wheeled skate-skis; a binding which is a combination of an outer shell of a firm material and an inner liner of soft material, which together are adjustable to fit different sizes and types of athletic shoes selected and worn by sportspersons; and a removable mud flap supportable on the binding to deflect water and/or debris thrown by a rea

Abstract: A skate, such as a roller skate or inline skate, comprises a shoe, a chassis and rollers or wheels suspended in the chassis. The skate also includes a braking system for at least one of the rollers or wheels. The braking system comprises a braking element which engages the roller and includes at least one actuation element for acting on the braking element. The braking force of the braking system is obtainable at low rotational or rolling speed of the roller to be braked and is small and increases with increasing rotational or rolling speed of the roller to be braked.

Abstract: The individual adjustment of cable length on a brake handle for cable-pull brakes on inline-skates, which is to be worn on the knee may be achieved, whereby an adjustment shaft (2) is arranged in the brake handle, around which the cable (5) may be rolled or unrolled and thus shortened or lengthened.

Abstract: A two-wheeled roller skate with canted wheels has an axle for the forward wheel located well forward of the ball of the foot. The axle for the rear wheel is located at the rear of the skater's heel. The wheels are canted so that the front and rear wheels contact the ground on the opposite sides of the center line of the skater's foot. In plan projection, the axles are preferably non-parallel in order to provide steering correction. The amount of steering correction desirable will depend on the skater's skill and the nature of the skating activity. In alternative embodiments, the present invention incorporates novel braking mechanisms.
