Definitions

  • the present invention relates to snowboarding. Specifically, the present invention relates to a snowboard having a contoured bottom surface.
  • Snowboarding remains a popular winter sport in many areas that have hills or mountains that are suitable for snow skiing. Unlike skis, snowboards require the rider to strap both feet to a single snow board and ride it in a stance similar to how a skateboard is ridden. Indeed, both snowboarding and skateboarding incorporate similar rider movements to control direction and speed.
  • a snowboard has a length defined by a nose end at the front end of the snowboard and a tail end at the rear end of the snowboard.
  • a snowboard's width is defined by two running edges that are substantially parallel to each other and run the length of the snowboard.
  • Examples of prior art snowboards include United States Patent No. 3,782,745, issued to Stovekin; U.S. Patent No. 4,974,868, issued to Morris; U.S. Patent No. 5,580,078 issued to Vance; U.S. Patent No. Des. 308, 996 to Katz, and U.S. Patent No. Des. 346, 194 to Ferris.
  • the Stovekin snowboard sought to improve steering and ride characteristics by adding steering skegs and shock absorption devices to a snowboard.
  • the Morris snowboard includes transverse channels and longitudinal grooves formed by longitudinal, downwardly-extending edges to facilitate movement through the snow.
  • the Vance snowboard includes running edges secured to the lower edges of the snowboard to improve handling characteristics of the board.
  • the Katz snowboard includes several shapes formed or cut in the upper surface of the snowboard for ornamental reasons.
  • the Ferris snowboard provides a two piece capped board with a fin-shaped tail.
  • snowboards are manufactured from laminated materials, which subjects snowboards to delamination problems and significant manufacturing cost.
  • Snowboards are subject to punishing conditions of being in constant contact with snow and ice while bearing the weight of a rider.
  • Aggressive riders demand snowboards that can withstand riders' jumping or "catching air” with the snowboard, which results in significant shock to the snowboard when landing on hardpacked snow or ice.
  • Another more common impact to a snowboard comes from colliding with obstacles such as rocks or trees, or other collisions that occur during transport.
  • Running edges bear the brunt of these collisions, which can damage the integrity of the snowboard.
  • some snowboards incorporate permanently-secured running edge guards attached to the running edges of the snowboard.
  • edge guards are typically so rigid and permanently affixed to the snowboard that they are an integral part of the snowboard, and define control and handling characteristics for the snowboard.
  • edge guards that are easier to maintain.
  • the laminated construction is usually fiberglass, plastic, and/or metal, and thus the rider cannot see the surface beneath the snowboard.
  • the present invention overcomes the shortcomings described above by providing a snowboard having a contoured bottom surface wherein a raised profile near the center of the bottom surface defines a pair of parallel, longitudinal channels through which snow is directed toward the tail end of the snowboard. Inboard from the tail end, aligned with at least one of the channels, an aperture is located that allows snow to be ejected vertically, forming a plume or rooster tail of snow as the rider passes over the snow. This vertical ejection of snow also helps keep the tail end of the snowboard in contact with the snow, which reduces chatter and improves handling of the snowboard.
  • the raised profile in the center of the bottom surface also provides rigidity to the snowboard as it is located beneath the area where a rider secures his boots in bindings on the top surface of the snowboard.
  • the raised profile has a shape that is substantially that of the profile of an hourglass, where a first round, raised area under the forward foot of the rider and the second round, raised area under the rear foot of the rider are connected by a longitudinal raised profile area, such that the raised profile protrudes outward from the bottom surface of the snowboard and makes contact with the snow or ice.
  • the preferred material for construction of the snowboard is transparent polycarbonate, formed in a single, non- laminated shape. This material is also easily recycled.
  • the snowboard is constructed from polymethyl methacrylate.
  • the preferred embodiment of the present invention is thin enough to allow the snowboard body to flex during riding, so that more of the snowboard's bottom surface remains in contact with soft snow, and absorb some shock while riding over hardpacked snow or ice.
  • the thickness of the snowboard typically varies from about 0.5 inches to about 0.25 inches.
  • the snowboard includes edge guards that are easily removed and replaces.
  • an edge guard can have an interior shape that is inserted into the channel and secures the edge guard to the running edge.
  • the leading point of the edge guard is secured also by a removable nose piece that attaches to the nose end of the snowboard, thus protecting the edge guard from forward-point collisions that might tear the edge guard lose from the snowboard.
  • FIG. 1 is a plan view of the bottom surface of the snowboard of the present invention.
  • FIG. 2 is an elevation view of the snowboard showing a cross sectional view from the aspect of the nose end of the snowboard.
  • FIG. 3 is a cross sectional view of the snowboard having exit holes for snow and ice channeled along the bottom of the snowboard.
  • Bottom surface 12 of snowboard 10 having a plurality of features of the present invention.
  • Bottom surface 12 includes first raised area 14, which in the preferred embodiment is located substantially under the forward boot binding on the top side of snowboard 10.
  • Second raised area 16 in the preferred embodiment, is located substantially under the rear boot binding on the top side of snowboard 10.
  • Connecting raised area 18 joins first raised area 14 to second raised area 16, and forms a divider that separates snow underneath snowboard 10 and guides it through channels 20, 22.
  • connecting area 18 extends no farther than between first raised area 14 and second raised area 16, as shown in FIG. 1, connecting raised area can extend beyond first raised area 14 and second raised area 16 to form a central rail protruding from bottom surface 12.
  • first raised area 14 and second raised area 16 are substantially circular shapes that protrude downward from bottom surface 12 and can be somewhat spherical, they also can be shaped as shown in FIG. 1 to streamline the diversion of snow between and along channels 20, 22.
  • Channels 20, 22 in the preferred embodiment are concave, longitudinal channels formed in bottom surface 12.
  • the side of channel 20 and edge 26 define edge rail 28, and the side of channel 21 and edge 30 define edge rail 32.
  • snowboard 10 includes a trimaran design, in which there are three runners or rails supporting snowboard 10, defined by edge rail 28 on one side, the combination of first raised area 14, second raised area 16, and connecting raised area 18 as the central rail, and edge rail 32 on the other side. Snow displaced by these rails is directed through channels 20, 22.
  • connecting area 18 is disposed between raised areas 14, 16, in an embodiment, connecting area 18 may be utilized in a design without any other raised areas, such as raised areas 14, 16.
  • channels 20, 22 include apertures 21, 23, respectively, through which snow passing through channels 20, 22 exit.
  • apertures 21, 23 are positioned such that snow passes through them, thus reducing the drag or resistance of the portion of bottom surface 12 that is located between apertures 21, 23 and tail end 24.
  • apertures 21, 23 have forward edge 25 and read edge 27, both of which are oriented at acute angles with respect to the plane defining bottom side 12. When operated at sufficient speed, snow exiting from apertures 21, 23 is ejected upward in a substantially vertical direction with respect to bottom surface 12, creating a plume or rooster tail that is not only aesthetic, but also exerts a downward pressure on tail end 24 of snowboard 10.
  • the plume or rooster tail generated by snowboard 10 is also effective for teaching other riders to maintain a safe distance from snowboard 10.
  • diverters may be placed over apertures 21, 23 to divert the plumes, such as to a desired degree to left or right, elevational configuration, apart from each other, etc. Connection of diverters to snowboard 10 can incorporate the connection technique of edge guard 34.
  • edge guard 34 is attached to edge 26 and edge guard 36 is attached to edge 30 to protect snowboard 10 from impacts such as collisions with obstacles and general wear and tear associated with transporting and storing snowboard 10.
  • Edge guards 34, 36 are flexible, extruded pieces of material, such as plastic or rubber, and include a key 38 that feeds into channel 40.
  • Channel 40 is formed in edges 30 and 32 and receives edge guards 34, 36.
  • edge guards 34, 36 can be made from sufficiently flexible material to allow them to be pressed or hammered into channel 40.
  • removable nose guard 42 also made from plastic, rubber or other durable material, can be secured on nose end 44, and hold edge guards 34, 36, in place.
  • edge guards 34, 36 can be shaped to provide channel 46 and edge rail 48. Edge guards having this profile can improve handling and steering characteristics for snowboard 10.
  • stiffener 50 is positioned above the central rail formed by connecting raised area 18 on bottom surface 12.
  • stiffener 50 incorporates flat sections that are secured between snowboard 10 and the rider's boot bindings that are attached to top side 52.
  • stiffener 50 snaps into channels 54 that are formed in top side 52. Stiffener 50 can be offered in a variety of flexibilities, and selected based on snow conditions or simply by rider preference.
