Abstract:
A snow ski or snowboard (20) having enhanced turning capability compared to traditional skis or snowboards has a split tip (22) and/or tail portion (24). The split tip/tail (22, 24) provides enhanced turning characteristics of the ski or snowboard (20). The split tips (22) and/or tails (24) may have additional active turning edges (38, 40) may have the same, or similar, curvature as the primary turning edge, thereby effectively increasing the length of the turning edge. A symmetrical or asymmetrical ski tail may be provided to further enhance turning on skis. Such a symmetrical or asymmetrical tail may have varying tail edge lengths, varying widths of split tails, interior edges, varying thickness of split tails, and/or varying core material of split tails that provides such enhanced turning ability.
Abstract:
The invention disclosed herein provides a replaceable edge cassette for skis or a snowboard. The skis have a top, a base, a core, two sides, and edges along the sides of the base. The cassette includes an edge portion removably secured adjacent the base of the ski. The edge portion has an attachment portion for securing the edge portion to the ski and a peripheral portion for contact with the surface to be ridden. The cassette includes a sidewall portion secured to the edge portion. A fastener is connectable through the sidewall portion to be secured to the ski adjacent the core. Base material is also secured beneath the removable edge portion so as to be adjacent the main base portion when the cassette is secured to the side of the ski. The edge cassette is removable and replaceable by removing the fasteners secured through the sidewall. The edge alone may also be separately replaceable by removing it from the sidewall portion.
Abstract:
The invention relates to sports equipments. The inventive ski is mainly appropriated for skating style. The ski comprises the following: an upper surface, a side internal surface, a side external surface and a sliding surface with a bottom surface and a bearing surface situated between the side internal surface and the bottom surface. The bearing surface comprises a ridge arranged along the longitudinal axis of the ski. The top of the ridge is placed not lower than the bottom surface. A part of the bearing surface which is placed behind the ridge and lies closer towards the side internal surface, is a flat surface inclined with respect to the bottom surface from 35 DEG to 60 DEG or a concave surface.
Abstract:
A double-edged snowboard (10) is disclosed. The snowboard includes a middle portion with a core, a tail (14) at the rear end of the middle portion, a shovel (12) at the front end of the middle portion, and a base (18) along the bottom of the middle, tail, and shovel portions of the snowboard. The base includes a central running surface (24), two outer running surfaces (26 and 28), first and second outer edges (34 and 36), and first and second inner edges (30 and 32). The central running surface is lower than the outer running surfaces. The first and second outer edges surround a portion of the perimeter of the first and second outer running surfaces, respectively. The first and second inner edges are disposed between the central running surface and the first and second outer running surfaces, respectively. The outer edges are generally symmetric about the longitudinal axis of the snowboard, whereas the inner edges may be positioned in a number of ways, depending on the desired performance characteristics of the snowboard. Asymmetric arrangements of the inner edges are disclosed that help accommodate for a skewed foot position on the snowboard. the disclosure also includes a method for manufacturing a dual-edged snowboard consistent with the above description.
Abstract:
On a pair of skis, a strip is mounted lengthwise to each ski's outer side along the ski center portion/grip zone. The strip's width is from 17 to about 60mm, height at most equivalent the ski thickness throughout, and length about equivalent the length of the ski grip zone. The strip's bottom inner edge is about smooth high with the ski base/sliding surface (A). The strip's underside (B) is widthwise outward sloping about 5 degrees upward related to the sliding surface (A). This underside (B) has an interleaving with a depth of about 2 mm, into which interleaving a piece of skins is attached, which skins constitutes the gripping surface (C). The inner edge of the gripping surface (C) then goes about 5 mm from the outer edge of the sliding surface (A), and the anterior, outer, and rear edges of the gripping surface (C) go about 2 mm from the respective adjacent bottom edges of the strip. Due to the described angel between the gripping surface (C) and the sliding surface (A), only the gripping surface (C) will be in contact with and rest on the substrate to give optimal grip, when this side is laid flat on the substrate. And only the sliding surface (A) will be in contact with and rest on the substrate to give optimal glide, when this side is laid flat on the substrate, due to the described distance as well to the angel between the two surfaces. Hence in order to get grip, stepping a bit over onto the outer side of the foot is required. With the Ski Grippers on the outer sides of the skis, the ski's inner bottom edges are retained for skating and for plow breaking in downhills. The Ski Grippers are meant fairly easily to be taken off the skis in conditions where they are less suitable.
Abstract:
Die Erfindung betrifft ein Sportgerät (1) wie beispielsweise ein Ski, ein Board oder dergleichen, welches zur alpinen, maritimen und aeronautischen Anwendung bestimmt ist, umfassend eine als Gleitfläche (2) ausgebildete Basislauffläche (3), welche sich über einen vorderen Bereich (4), einen mittleren Bereich (5) sowie einen hinteren Bereich (6) erstreckt. Erfindungsgemäß umfasst dabei die Gleitfläche (2) ein Mehrkanten-Profil (10, 11, 12, 13), welches im Querschnitt, symmetrisch zur Mittelachse (7) des Sportgerätes (1), mindestens ein V-Profil (8) und (9) pro Seitenbereich der Gleitfläche (2) aufweist.
Abstract:
Briefly, in accordance with one or more embodiments, a snowboard or ski or the like comprises a base body having at least one edge, a top surface and a bottom surface; wherein the edge comprises at least one channel formed therein to provide two or more edge elements to contact a medium during use.
Abstract:
A snow glider comprises a longitudinally-extending runner for supporting a rider on ridden snow and having a generally central, longitudinally-extending slot. The glider further comprises an elevated rider-supporting deck and chatter-absorbing means straddling the slot for supporting the deck above the runner. Preferably, the bottom surface of the runner is preferably generally convex across its width, with curved outer edges that provide directional control to the rider when turning, and at least one longitudinally-extending, generally straight longitudinally- extending inner edge adjacent the periphery of the slot for greater directional control when the rider is going straight. To enhance controllability, the deck of the preferred embodiment is preferably coupled to the runner near the runner's outer periphery so that the force exerted by the rider is transmitted from his/her feet directly to the outer edges of the runner. To further reduce frictional contact with the snow, the bottom surface of the runner is preferably dimpled.
Abstract:
Die Erfindung betrifft allgemein ein Wintersportgerät, insbesondere einen Schlittschuh, mit dessen Kufen ein Gleitmesser (3) lösbar verbunden ist. Die Gleitfläche (1) dieses Gleitmessers (3) ist mit wenigstens einer, hier mit drei, in Bewegungsrichtung verlaufenden Profilrillen (4) versehen. Beidseitig dieser Profilrillen (4) erstrecken sich wulstartige Dämme (5).
Abstract:
Gliding board equipment systems and individual components are disclosed herein. A gliding board equipment system of one embodiment includes a gliding board, a boot having an upper cuff and a lower boot, and a binding selectively attaching the boot to the gliding board. The upper cuff of the boot defines opposed slots, and a respective pin passes through each slot to couple the upper cuff to the lower boot and allow the upper cuff to move laterally relative to the lower boot.
