  • Publication number: 20020043782
    Abstract: A snowboard binding system includes a boot and a binding configured to be releasable coupled together. The boot has a mid sole constructed of a first material and an outer sole constructed of a second material. The first material has a lower coefficient of friction than the second material. First and second rear catches are formed on first and second lateral sides of the mid sole to engage a rear binding arrangement of the binding. A front catch of the boot selectively engaes a front binding member of the binding. The outer sole partially covers the mid sole such that the mid sole is exposed in an area adjacent at least one of the first and second lateral sides. The binding includes a base member with rear guide member has an upper boot support surface arranged to contact the exposed area of the mid sole.

  • Publication number: 20020043783
    Abstract: A snowboard binding system includes a binding and a boot configured to be releasably coupled together. The snowboard binding includes a base member, a rear binding arrangement, and a front binding arrangement. The snowboard boot includes an upper portion, a sole portion, at least one rear catch and a front catch. The sole portion has a toe section, a mid section and a heel section. The rear catch is located at the heel section of the sole portion. The front catch is coupled to the toe section and has a pair of leg portions extending downwardly from the toe section of the sole portion, and a tongue portion extending laterally between the leg portions. The toe section has a pair of front catch guide surfaces located forwardly and laterally of the front catch to guide the front catch toward the front binding arrangement.

  • Patent number: 6325405
    Abstract: An active high back system is provided for automatically adjusting the snowboard boot between a walking position and a riding position. The snowboard boot is provided with an active highback support that is adjustably mounted to a snowboard boot. During walking, the active highback support does not constrain the flexibility of the snowboard boot making it possible for the snowboard rider to walk easily. When the rider steps into the bindings of the snowboard, the active highback support engages a part of the snowboard or binding that causes the snowboard boot to lean forward. In other words, the highback support is positioned to engage the back leg portion of a snowboard boot to provide a rigid surface that holds the boot in a forward leaning position. The active highback support is provided with an adjustment mechanism that allows the rider to adjust the amount of forward lean when the snowboard boot is engaged within the bindings of the snow board.

  • Patent number: 6231128
    Abstract: A bicycle wheel basically has a hub, a plurality of spokes extending outwardly from the hub and an annular rim coupled to the outer ends of the spokes for supporting a tire. The annular rim has a spoke attachment portion with a plurality of openings for receiving the outer ends of the spokes therein. The outer ends of the spokes are bent such that first sections of the spokes are offset from sections of the spokes. These bends are positioned in the openings of the rims to retain the outer ends of the spokes in the openings of the rim. Optionally, an adhesive may be used to more securely retain the outer ends of the spokes in the openings of the rim.

  • Patent number: 6155577
    Abstract: The present invention relates to a highback support which is pivotally mounted to a support member. A lever mechanism fixed to a backside of the highback support includes a lever which selectively engages a portion of the support member and provides mechanical advantage for setting and releasing the highback support between a support position and a release position. In the support position, the highback support is positioned to engage the back of a snowboard boot to provide a rigid surface against which a snowboard rider can lean for steering. In the release position, the highback support is free to pivot making it possible for the snowboard rider to walk easily.

  • Patent number: 6119372
    Abstract: The invention relates to a shoe lacing configuration where short straps attached to sides of an article of footwear are formed with loops. A secondary lacing strap includes loops through which a lace extends. The lace extends through lacing means formed on opposite sides of a boot and further extends through the loops in the secondary lacing strap. The secondary lacing strap has the effect of doubling the force applied to the lace on the opposite sides of the boot in a manner similar to that of a block and tackle thus improving the lace tightening characteristics of the article of footwear.

  • Patent number: 6073370
    Abstract: The invention relates to a shoe lacing configuration for an article of footware such as a boot, where the boot is provided with two rings, one ring supported on either side of the boot proximate an ankle supporting portion of the boot. A long strap is looped through the two rings such that the long strap defines an elongated C-like shape. Each end of the long strap is formed with eyelets. A lace extends through eyelets formed in the boot in a traditional criss-cross manner, and the lace further extends through the eyelets formed in the long strap. The long strap has the effect of doubling the force applied to the lace in a manner similar to that of a block and tackle thus improving the lace tightening characteristics of the boot.
