The pole includes a user-grippable region and a snow-engaging region and selectively extends between a collapsed position and an extended position. The receiver is secured about a portion of the user's body, such as a non-articulating portion of a user's limb, and includes a pair of spaced-apart retainers, each adapted to selectively receive and retain the collapsed pole.

  • Patent number: 6142526
    Abstract: The present invention relates to a speed control pole to be used by a skater. The speed control pole has an elongated shaft with an upper end and a lower end, a roller/wheel mounted to the lower end of the shaft, a braking mechanism for contacting the roller, and a hand grip system for actuating the braking mechanism. The braking mechanism includes a brake pad which is caused to be moved inwardly against the roller and downwardly into contact with a skating surface when actuated. The brake pad includes an arcuately shaped surface for contacting the roller and a lower surface formed by two angled substantially planar surfaces. During a braking mode of operation, the arcuately shaped surface is brought into contact with the roller. During a pushing off mode of operation, the arcuately shaped surface remains in contact with the roller and the substantially planar surfaces are sequentially brought into contact with the skating surface.

  • Patent number: 6142527
    Abstract: The invention concerns a A stick such as a ski pole, a walking stick or the like, which has a pole grip and a pole tube, the length of which can be altered, as well as an adjusting device with which at least one gripping area of the stick pole grip can be adjusted in a bent position relative to the pole tube. The purpose of the invention is to obtain a stick which can be folded into a compact unit as small as possible. To this end the pole tube has two sections joined together by the adjusting device and the adjusting device is accommodated outside of the pole tube of the stick.

  • Patent number: 6003915
    Abstract: An improved snow shovel with a telescoping handle comprised of a plurality of tubular elements, the outermost element having a grip at one end and the innermost element having a tip at the opposite end; a detaching blade, and a permanently mountable secondary tip and manually mounting removable basket. With the blade removed, the handle telescopes to a length greater than seven feet thus converting into a singular rod or snow probe used to feel or probe for buried victims in avalanche debris. When the handle is retracted, the blade is attached and the outermost telescoping element extends outwardly to a locked position. This increases leverage when digging to recover avalanche victims. With the blade detached and the handle extended, the secondary tip secures to the primary tip on the innermost element. This allows the snow basket to be mounted. The handle is then adjustable to any one of several positions for use as a spare ski pole when necessary.

  • Patent number: 5941435
    Abstract: A single, telescoping, collapsible, quick-release snowboarding pole with leg mounting system includes a telescoping, collapsible pole and leg mounting assemblies, to secure the pole, in the collapsed position, to the lower leg of an individual, such as a snowboarder. This invention allows the user to quickly release the collapsed pole from the leg mounting assemblies and extend and lock the telescoping pole, to use as needed, usually to gain momentum while snowboarding or performing other outdoor sports. The pole comprises three sections of telescoping tubing, the lower pole section sliding into the middle pole section which then slides into the upper pole section, in the collapsed position. The pole is locked into its extended position by way of two snap-lock buttons positioned inside the middle and lower pole sections, respectively.

  • Patent number: 5651565
    Abstract: A locking structure for two telescoping tubular members is provided with an outer tube member and an inner tube member slidable inside the outer tube member. An expansion member is located within the outer tube member. The expansion member contains at least two tapered members each having innermost and outermost portions, the outermost portions being spaced no more than 1/2 inch from each other. On the expansion member is an outer tube pressure member shaped to fit the expansion to member and disposed between said the expansion member and the inner surface of the outer tube member. The expansion member may be attached to the inner tube member. The expansion member is moved in opposite directions inside the outer tube member so that when said expansion member is moved in a first direction, pressure is directly applied to the outer tube pressure member which in turn applies pressure to the inner surface of the outer tube member thereby maintaining the inner and outer tube members in a locked position.

  • Patent number: 5538354
    Abstract: A locking device for mutually locking two adjacent sections of a telescoping tubular assembly. An axial extension (7) on one of the tubular sections (2) supports an expandable ring (10) received in the other tubular section (1). A nut (17) is non-rotatably slidable in the ring (10) and screwed onto a threaded portion of the axial extension (7). The ring (10) is itself non-rotatable relative to the first tubular section (1). Relative rotation between the tubular sections (1, 2) moves the nut (17) towards the second tubular section (2) and causes the ring (10) to be expanded by tapered portions (15, 16). The ring is deformed in several places to spread the frictional load.

  • Patent number: 5478117
    Abstract: An adjustable length ski pole includes two telescopically fitted together ski pole halves, and a clamp disposed about the joint between the two pole halves. The clamp includes a resilient tubular member having an annular sidewall which defines a cylindrical bore, where the sidewall is formed with a longitudinally extending gap to allow the tubular member to be selectively biased to reduce the gap width and thus the diameter of the bore, or to enlarge the gap width and thus the diameter of the bore. The gap defines first and second opposing sidewall edges having coaxial first and second openings respectively.

  • Patent number: 5470108
    Abstract: A ski pole assembly and a ski pole and ski glove combination. The grip includes a central core member of a relatively hard low friction material and an outer sheath member of a relatively soft high friction material. The core member includes raised pads proximate the upper end of the grip and the sheath includes windows receiving the pads so as to expose the pad surfaces and provide low friction pivot areas proximate the upper end of the grip to facilitate the swinging movement of the pole. The core member includes a downwardly opening bore receiving the upper end of the shaft of the ski pole and allowing the shaft to be adjustably positioned in the bore to selectively vary the overall length of the ski pole.

  • Patent number: 4793627
    Abstract: A paired, sporting, ski-steering device for use with a pair of skis with the skier's feet locked in position by standard ski bindings, providing the skier with an upright handlebar for each ski, both skis being totally independent from one another. The handlebars are attached to the front of each ski at mid-position between the toe piece of the standard ski binding and the front tip of the ski. The handlebars telescopically adjust in height so when retracted to a short length they reach vertically from approximately the knee to the mid-thigh of the skier so he/she can use this ski steering device in a tucked-in position; when extended, these handlebars are easily and manually detachable from the skis and instantly become a full length ski pole adjustable to the skier's height and comfort. Various locking devices to readily lock/unlock these handlebars to the skis are described.
