Definitions
- a skateboard includes a board with wheels attached to the underside, and is designed for riding on a sidewalk or in a specially designed skate park.
- a snowboard includes a board with a waxed underside and bindings for securing the feet of a rider to the snowboard, and is designed primarily for riding on a snow-covered slope or in a specially designed snow park.
- Riding a skateboard is similar to riding a snowboard in that the rider assumes a sideways stance on both types of boards.
- one primary difference is that, in skateboard riding, the rider's feet are free to leave the surface of the skateboard, whereas in snowboarding, the rider's feet remain securely attached to the snowboard.
- Skateboard riding has evolved to include a host of well known tricks such as ollies, kickflips, shovits, etc., which take advantage of the ability to remove the rider's feet temporarily from the skateboard during performance of the trick. These tricks are not able to be performed on current snowboards because the bindings prevent the rider's feet from leaving the snowboard.
- skateboards are unable to be ridden successfully on snow, because the wheels of the skateboards dig into the snow and cause the skateboards to stop suddenly. Attempts to ride skateboards on snow generally result in crashes. For riders who reside in cold-weather climates, this renders skateboards unusable outdoors during the snowy season, which may last for many months.

Description
- This application is a continuation-in-part of U.S. patent application Ser. No. 09/798,502, filed Mar. 1, 2001, which in turn claims priority to U.S. patent application Ser. No. 09/518,231, filed Mar. 2, 2000, now issued as U.S. Pat. No. 6,290,249. The entire disclosures of U.S. patent application Ser. No. 09/798,502 and U.S. Pat. No. 6,290,249 are herein incorporated by reference.
- The sports of skateboarding and snowboarding have reached new heights of popularity in recent years. A skateboard includes a board with wheels attached to the underside, and is designed for riding on a sidewalk or in a specially designed skate park. A snowboard includes a board with a waxed underside and bindings for securing the feet of a rider to the snowboard, and is designed primarily for riding on a snow-covered slope or in a specially designed snow park.
- Riding a skateboard is similar to riding a snowboard in that the rider assumes a sideways stance on both types of boards. However, one primary difference is that, in skateboard riding, the rider's feet are free to leave the surface of the skateboard, whereas in snowboarding, the rider's feet remain securely attached to the snowboard. Skateboard riding has evolved to include a host of well known tricks such as ollies, kickflips, shovits, etc., which take advantage of the ability to remove the rider's feet temporarily from the skateboard during performance of the trick. These tricks are not able to be performed on current snowboards because the bindings prevent the rider's feet from leaving the snowboard.
- One problem with current skateboards is that they are unable to be ridden successfully on snow, because the wheels of the skateboards dig into the snow and cause the skateboards to stop suddenly. Attempts to ride skateboards on snow generally result in crashes. For riders who reside in cold-weather climates, this renders skateboards unusable outdoors during the snowy season, which may last for many months.
- It would be desirable to provide an apparatus that is capable of being ridden in the snow, and that is configured to allow temporary removal of a rider's feet from the apparatus, to enable a rider to perform a wide variety of maneuvers.
- A gliding apparatus for use in snow is provided. The apparatus typically includes an elongate member including an intermediate portion positioned between a pair of longitudinally opposed upturned end portions. The elongate member includes a bottom surface configured to glide over snow and a laterally upwardly curved surface. The apparatus further includes a traction layer positioned above the elongate member. The traction layer is typically a pliant foam layer.
- According to another aspect of the invention, a gliding apparatus is provided that includes an elongate member having an intermediate portion positioned between a pair of longitudinally opposed upturned end portions. The elongate member includes a bottom surface configured to glide over snow. The apparatus further typically includes a stringer imbedded in and extending lengthwise along the elongate member. The stringer may be made of laminated wood, or other suitable material. The apparatus may also include a traction layer positioned above the elongate member and stringer. The traction layer is typically pliant foam.
- According to another aspect of the invention, the gliding apparatus may include an elongate member having an intermediate portion positioned between a pair of longitudinally opposed upturned end portions and a bottom surface configured to glide over snow, where the elongate member is formed of a first and a second layer of material, the first layer being stiffer than the second layer. The apparatus typically also includes a traction layer positioned above the elongate member. The first and second layers may be co-extruded and/or high-density polyethylene. The first layer may include a stiffener, such as talcum. The apparatus may further include a channel extending lengthwise along the bottom surface of the elongate member, the channel being configured to guide the elongate member over snow.
- According to another aspect of the invention, the gliding apparatus includes an elongate member having an intermediate portion positioned between a pair of longitudinally opposed upturned end portions, the elongate member including indicia on a surface. The apparatus further typically includes a translucent layer positioned adjacent the surface such that the indicia is visible through the translucent layer. The apparatus may also include a channel extending lengthwise along a bottom surface of the elongate member, the channel being configured to guide the apparatus over snow. The indicia may be on a top surface of the elongate member and the translucent layer may be a traction layer positioned above the elongate member. Alternatively, the indicia may be on a bottom surface of the elongate member and the translucent layer may be positioned below the elongate member.
- According to another aspect of the invention, the gliding apparatus may include an elongate member including an intermediate portion positioned between a pair of upturned end portions, the elongate member including a bottom surface. The apparatus may further include a plurality of substantially parallel channels extending lengthwise along the bottom surface of the elongate member, adjacent channels being separated by rounded ridges extending therebetween.
- According to another aspect of the invention, the gliding apparatus includes an elongate member including an intermediate portion between a pair of upturned end portions, the elongate member including a bottom surface configured to glide over snow and a pair of opposed side edges, each of which tapers to a point at an angle of between about 30- and 60-degrees. In one embodiment of the invention, the angle may be formed between about 40- and 50-degrees, and in a particularly preferred embodiment, 45 degrees. The apparatus further typically includes a traction layer positioned above the elongate member.
- According to another aspect of the invention the gliding apparatus includes an elongate member including a top surface with a rim and depression configured to retain a traction member, and one or more channels, where one of the channels is a central channel that is wider than the remaining channels and is configured to facilitate sliding along a rail.

Channels 26 typically open to the leading end of the apparatus, as shown in FIG. 5, as well as to the trailing end of the apparatus, which typically is symmetric to the leading end shown in FIG. 5. As the apparatus passes over a snow-covered surface, snow underchannels 26 is guided into the channels, while snow under substantially planar regions ofbottom surface 22 is compacted. Thus, snow under channel-group dividing portion 30, channel-separatingportions 32, and right-side and left-side surface portions channels 26, if compacted at all, is not compacted so much as snow under the planar regions ofbottom surface 22. This creates ridges in the snow, along whichchannels 26 are configured to slide.
