  • Publication number: 20100308549
    Abstract: One embodiment of the present invention sets forth a temporary binding apparatus for binding a snowboard boot to a snowboard. A magnetic element is affixed to the snowboard and a permeable element is affixed to the snowboard boot. The magnetic element and permeable element are configured to develop a binding force that is a function of a rotation angle between the magnetic element and permeable element. In an engaged configuration, the permeable element is aligned with the magnetic element and the binding force should be sufficient to enable a snowboarder to readily perform certain simple maneuvers, such as dismounting a chairlift. A pivot means is formed by joining the permeable element and magnetic element. The pivot means enables the snowboarder to easily rotate the permeable element into misalignment with the magnetic element, thus decreasing the binding force and enabling easy detachment of the snowboard boot from the snowboard.

    Abstract: A contact system for a sport board allows a rider to maintain contact between her feet and the sport board while performing aerial maneuvers. The boarder wears magnetic footwear such as a bootie (for surfing), sheath (for surfing), or shoe (for skateboarding) with an affixed magnet. The board has a contact patch that includes a plate of ferrous metal or another magnet oriented such that it attracts the magnetic footwear. The contact patch is positioned such that it will be stood on by the boarder. During normal boarding and aerial maneuvers, magnetic attractive forces between the footwear and the contact patch will maintain contact between the boarder's feet and the board. However, when the boarder falls, the magnetic attractive forces do not bind the boarder's feet to the board.

  • Patent number: 6007086
    Abstract: An electric ski binding system with magnetic interfaces and a microprocessor achieves releasable engagement of a ski boot to ski bindings. A permanent magnet in the front ski binding and a permanent magnet of opposite polarity in the toe portion of the boot create a front magnetic interface. A permanent magnet in the rear ski binding and a permanent magnet of opposite polarity in the heel portion of the boot create a rear magnetic interface. Electromagnets in the proximity of the front and rear magnetic interfaces are disposed so that their polarity opposes the permanent magnets of the boot. The electromagnets are turned off while the boot is engaged with the ski binding to allow the permanent magnets to couple at the front and rear magnetic interfaces. The electromagnets are operated when disengaging the boot from the ski binding to create a magnetic field substantially greater than that of the permanent magnets in the front and rear magnetic interfaces.

  • Patent number: 5845896
    Abstract: A vehicle suspension system (110) having a primary suspension system (112) and a secondary suspension system (114). Vertical motion of a vehicle wheel (120) places a force on the vehicle frame (126) which, in turn, places a force on the vehicle body (124). The secondary suspension system (114) translates the relative motion between the wheel (120) and frame (126) into a force on the vehicle body (124) which is equal and opposite to the force transmitted from the frame (126) to the body (124). A frictional shock absorber (300) is utilized in the suspension system (110) as well as a multi-stage coil spring (400).

  • Patent number: 5797607
    Abstract: An all-terrain vehicle including centrally pivoted bogies on opposite sides of the vehicle body, a primary yoke mounted on the vehicle body and extending crosswise to the vehicle body for coupling the bogies to each other, a secondary yoke mounted on the vehicle body and connected to the vehicle body by hydraulic cylinders at opposite ends thereof, and a selectively actuatable clutch for coupling the secondary yoke to the primary yoke so as to cause the hydraulic cylinders to drive both yokes a desired amount to positively move the bogies to a desired position, and hydraulic circuitry coupled to the hydraulic cylinders for applying a pulsating action to the bogies which is transmitted to the vehicle wheels mounted on opposite ends of the bogies for increasing traction of the wheels on surfaces such as snow, ice, mud and sand.

  • Patent number: 5779257
    Abstract: A system for damping and/or stiffening a ski having a damping member and a stiffening member which are engageable and disengageable through the operation of a switch member. The switch member is engaged by a change in a threshold condition, such as a shift in the skier's weight during skiing. Engagement of the switch member engages the damping member and/or stiffening member. The system maintains the damping member and/or stiffening member in a disengaged condition until the skier commences a turn, engages the damping member and/or the stiffening member during the turn, and disengages the damping member and/or the stiffening member once the turn is completed.

  • Patent number: 5769502
    Abstract: The present invention relates to a levelling system for motor vehicles which allows the shaft that hinges a truck body or other loading surface defining a loading structure, to an auxiliary frame defining, or forming part of, the vehicle's supporting structure, to remain horizontal so as to enable the body or loading surface to be used effectively; the levelling system basically includes a device for detecting the inclination of the hinge shaft to the horizontal and a mechanism for adjusting the inclination consisting of a bracket or lever placed between the supporting structure and the loading structure, pivoted to a second shaft and operated on by at least two variable extension elements connected to the supporting structure and designed to vary the inclination of the latter in accordance with the readings of the detecting a mechanism.

  • Patent number: 5743550
    Abstract: An electronically controlled safety binding opens in response to forces transmitted to a ski boot or a snowboard shoe. The safety binding opens when the transmitted forces exceed a threshold amount. To shorten time for opening the safety binding, the safety binding is provided with a piezoelectric crystal which triggers an ignition of an explosive charge. The explosive charge drives a bolt which causes the safety binding to open at a faster rate.

  • Patent number: 5709394
    Abstract: A utility vehicle, such as a grape harvester (1), comprises a straddling frame (2), supported at its front and rear ends by double-acting hydraulic cylinders (17, 18 and 23, 24), which can be extended or retracted for levelling the frame (2). During horizontal or uphill travel, the rear cylinders (23, 24) are blocked for providing the vehicle (1) with a fixed rear axle (55), while the front cylinders (16, 17) are hydraulically interconnected in order to let them extend or retract in opposition to each other for providing the vehicle (1) with an oscillating front axle (56). During downhill travel the front cylinders (17, 18) are blocked for fixing said front axle (56) to the frame (2) and the rear cylinders (23, 24) are hydraulically interconnected for letting the rear axle (55) oscillate to the frame (2). The rear and front oscillation is controlled by an inclination sensor (91).

  • Patent number: 5700026
    Abstract: A vehicle body lowering system for installation in a motor vehicle having a wheeled carriage, a cargo/passenger compartment body, a door in the passenger compartment body for cargo loading and unloading or passenger embarking and debarking, and a spring suspension for the buoyant support of the body above the carriage between a lower position and an upper position. The components of the vehicle body lowering system include a hydraulic cylinder mounted within the body, a power source, a manually actuated control for energizing and deenergizing the power source, and an interconnection extending through the body between the cylinder and the carriage. The interconnection is characterized by an operative condition at which the body is in the lower position under the control of the power source, and an inoperative condition at which the body is freely subject to the buoyant support of the spring suspension.
