  • Patent number: 7216888
    Abstract: The present invention relates to a ski binding that retains a boot to a ski in at least two independent operational states. One embodiment of a ski binding includes a toe receiving member and a releasable system. The toe receiving member is configured to engage the toe portion of the boot. The releasable system is configured to couple the toe receiving member to the ski in at least two independent operational states. A first state corresponds to a state in which the toe receiving member is allowed to freely rotate with respect to the ski. The first state is particularly useful in minimizing the necessary energy output for uphill travel. A second state corresponds to a state in which the toe receiving member is locked with respect to the ski. The second state is particularly useful in high performance downhill travel. The releasable system further includes an engagement mechanism and a switching mechanism.

  • Patent number: 7216890
    Abstract: The present invention relates to an improved telemark ski binding. More particularly, the present invention relates to a dual front cable under-foot telemark binding. The two front cables attach to a linkage point within the toe receiving portion. The front cables are also designed to be easily replaceable by a consumer thereby extending the overall lifespan of the binding. In addition, the coupling between the two front cables and the resistance mechanism cartridges includes a unique rotational and lateral chalking mechanism that prevents inadvertent adjustment.

  • Publication number: 20060175802
    Abstract: A resilient biasing element for a snowboard binding is disclosed. The biasing element provides a means of biasing an ankle or toe strap for a conventional snowboard binding towards an open position when the strap is unsecured, easing the insertion and removal of a boot from the binding. The binding may be used in combination with a conventional snowboard, or a snowboard incorporating impact plates to distribute loads and increase the structural integrity and life of the snowboard.

  • Publication number: 20060082103
    Abstract: The present invention relates to an adjustable ski skin attachment device that can be used to efficiently attach a skin to a ski or snowboard. In accordance with the present invention, an adjustable ski skin attachment device includes two threaded members, a coupler, and a cover. The two threaded members are threaded in reverse directions from one another. The coupler includes two receiving portions with reverse threaded receiving portions such that when the threaded members are inserted into the two receiving portions and the coupler is rotated in one direction, the two threaded members move closer together. And when the coupler is rotated in the opposite direction, the two threaded members move away from one another. The cover is positioned over the two threaded members opposite the coupler. Unlike conventional skin attachment devices, the adjustable ski skin attachment device in accordance with the present invention can be adjusted to fit over a wide variety of widths and tip shapes.

  • Publication number: 20060001239
    Abstract: The present invention relates to a radius surface for use on a ski binding resistance mechanism cartridge. The radius surface of the present invention enables a cable coupled to the resistance mechanism cartridge to bend directly adjacent to the cartridge. Since the cable is able to bend adjacent to the cartridge, the overall functionality of a binding is improved. In addition, the radius surface can be adjusted to specifically dictate the exit bend radius allowed on the cable coupled to the resistance mechanism cartridge.

  • Patent number: 6347805
    Abstract: One embodiment is directed to a system for mounting a rider to a snowboard, and an interface for use in such a system. The system comprises a snowboard boot, a snowboard binding and an interface having at least one mating feature adapted to be releasably engaged by the snowboard binding. The interface further includes at least one strap adapted to mount the interface to the snowboard boot. The outer sole of the snowboard boot includes a recess rearward of the arch area that is adapted to receive the interface so that the interface does not protrude below the outer sole when the interface is mounted to the snowboard boot. In another embodiment, the interface includes a base that is adapted to pass under the sole of the snowboard boot, the base having a non-planar contoured upper surface that is adapted to fit within a recess in a sole of the snowboard boot.

  • Patent number: 5947507
    Abstract: A cross-country ski binding for mounting on a ski to hold a ski boot includes a base plate for mounting on the upper surface of the ski. The base plate has a front section on which a resilient compression element, such as a spring, is mounted. The compression element is coupled to a forward end of a cable so that when rearward force is applied to the cable, the compression element provides resistance to the rearward movement of the cable, and then expands to pull the cable forward when the rearward force is removed. A toe plate is mounted on the base plate for receiving and holding a ski boot toe. The toe plate has a channel formed below the upper surface thereof, which extends from the front section rearwardly for receiving the cable. The cable is coupled at the forward end to the compression element and extends rearwardly through the channel.
