  • Patent number: 5236222
    Abstract: A skate pole device can be used alone or in pairs by a roller skater in order to advance or retard movement along a skate surface. The skate pole has an elongated shaft with a handle portion on one end and a foot portion on the other end. First and second pads are mounted in the foot portion. The first pad is constructed of a type adapted to frictionally grip the skate surface so that the skater may exert a thrusting motion with the skate pole, and this material may be a stiff, yet resilient, rubber-like substance such as a soft thermoplastic. The second pad is constructed of a different type of material, such as a hard thermoplastic, that is adapted to act as a brake pad against the skate surface so that the skater may apply a drag force. A pair of such skate poles may be used and, if desired, interconnecting elements are provided to releasably secure two such skate poles alongside one another.

  • Patent number: 5236216
    Abstract: A binding for snowboards comprises a rotatable base plate (1) which, when mounted, is directly in contact with the surface of the snowboard (25). The base plate (1) includes a circular central opening (2) through which protrudes a circular fastening disc (14) formed with a projecting rim (15) which extends over the opening (2) in the base plate. The fastening disc (14) is adapted to be threadedly engaged with the snowboard (25), thus pressing the base plate against the snowboard. The fastening disc has oblong holes (18, 19, 20, 21) which allow longitudinal shifting of the entire binding.

  • Patent number: 5234073
    Abstract: A front wheel drive for use in motor vehicles has an engine which extends transversely of the direction of forward movement of the vehicle. The output element of the engine drives the input component of a continuously variable chain or belt transmission with adjustable sheaves which drives a differential with two coaxial output components serving to drive the front wheels. The axis of rotation of the output element of the engine is normal to the axes of rotation of primary and secondary cones of the infinitely variable gearing, and to the axes of rotation of the output components of the differential. The axes of rotation of the output components are parallel to axes of rotation of the primary and secondary cones.

  • Patent number: 5234224
    Abstract: Multi-function baby support and transport apparatus including a wheeled, vertically-extensible frame, the uppermost member of which is adapted to carry a baby seat. The frame includes locking means for locking it in several different configurations, in each of which configurations the uppermost member is at a different elevation from a horizontal plane surface which bears the apparatus. A propelling handle is pivotably mounted on the uppermost member and can be positioned in an upright propelling position or in a horizontal position in which it is closely juxtaposed to the uppermost member. A folding diaper changing table is affixed to the propelling handle, and thus can be used for changing diapers when the propelling handle is in a horizontal position.

  • Patent number: 5232231
    Abstract: A brake for roller skates comprising a simple, lightweight mechanism which multiplies the force exerted by the skater into a substantial braking force. The force is exerted by the skater by pushing downward with the heel, which rotates the boot with respect to the frame of the skate. That force is transmitted with leverage to braking shoes or pads that impinge on brake drums adjacent to the wheels. Adjustment for brake wear is provided by a screw that compensates for the shortening of the brake shoe as normal wear occurs. A detent mechanism locks the boot and frame together during normal skating.

  • Patent number: 5230523
    Abstract: A multi-functional child carrier device including a base having a detachable seat, the backrest portion detachably connectable to the base and slots formed within both the back-rest and the base to allow the unit to serve as a child safety seat or as an infant carrier seat utilizing only the backrest. The device includes elevation supports secured and retractable within the base for supporting the base in an elevated position so that the device may function as a child's chair. Wheels are attachable to the elevation supports so that the device may function as a stroller. Extension members may be attached to the retractable legs for further elevation of the device, thereby allowing the device to function as a high chair. Upon removing the backrest portion, and inserting the appropriate seats on the base, the device may function as either a potty-chair or a walker. In addition, the base is configured in such a manner that if inverted, the unit may function as a rocking chair for a small child.

  • Patent number: 5228719
    Abstract: An automotive suspension control system for anti-rolling motion control is provided. This system serves to adjust wheel loads acting on driven wheels when a wheel speed difference between the driven wheels is greater than a preselected value, concluding that slippage occurs at one of the driven wheels, the adjustment is carried out for securing traction of a slipping driven wheel. The system is responsive to lateral acceleration acting on a vehicle body to decrease a degree of adjustment of the wheel loads according to increase in the lateral acceleration for enhancing cornering stability on road surfaces having different friction coefficients.

  • Patent number: 5226500
    Abstract: A vibration sensor is disposed at an evaluation point on the vehicle floor proximate the driver's seat. This sensor, in combination with one disposed on a electrically controllable engine mount, is used to determine the magnitude and orientation of a vector of vibration which reaches the evaluation point and which combines with other vibrational vectors in a manner which results in the generation of vibration at the evaluation point. A mount control signal is controlled in a manner which modifies the vibration vector and attenuates the vibration at the evaluation point.

  • Patent number: 5226501
    Abstract: Several embodiments of electric power assisted bicycles wherein an electrical motor is employed for assisting in the pedaling of the bicycle. The embodiments all include an arrangement for changing the state of the electrical power in response to pushing of the bicycle. In some embodiments, the circuit for the electric motor is opened when the bicycle is pushed rearwardly so as to avoid undue resistance to the pushing as might occur due to the fact that the motor would operate as a generator under this condition and provide an electrical load. In other embodiments, the electric motor is energized upon pushing so as to assist in pushing the bicycle.

  • Patent number: 5224729
    Abstract: A binding for a cross-country ski shoe in which the shoe is mounted for pivotal movement about an axis transverse to the longitudinal axis of the ski. An elastic bumper exerts a return force on the shoe when the shoe is lifted from the upper surface of the ski. The elastic bumper is brought into a prestressed condition during the closing of the binding. The prestressing is achieved by either the displacement of the shoe with respect to the elastic bumper or displacement of the elastic bumper with respect to the shoe. This displacement may either be slidable or pivotal movement of a carriage.

  • Patent number: 5224721
    Abstract: An improved walker in which a gate which is pivoted on one rear leg for movement from an open position to a closed position at which it engages a fitting carried by the other rear leg, supports a seat for pivotal movement from a raised inoperative position to a lowered operative position. An element operative in the lowered position of the seat prevents the gate from moving to an open position. Interengageable elements operative in the open position of the gate prevent the seat from being lowered.
