Description
- This application is a continuation of U.S. patent application Ser. No. 11/084,210, which is incorporated herein by reference in its entirety for all purposes.
- The present invention relates to snow sleds. More specifically, the present invention relates to snow sleds wherein the user rides the snow sled in an upright sitting position and the snow sled has steering capabilities. Children and adults alike enjoy the exhilaration of snow-sledding. Children and adults also have particular interests associated with various hobbies and interests such as race cars, space-ships, trains, and motorcycles. The illustrated embodiment in the present application, for example, takes the form of a chopper-style motorcycle—that is a motorcycle with long, backward-sloping forks and handlebars, a tear-shaped fuel tank, and a laid-back seating configuration. Embodiments of the present invention, however, are not limited to that of a motorcycle and can take the form of various shapes and configurations.
- Two types of snow sleds are saucer sleds and the steel runner sleds. Saucer sleds are typically simple round plastic dishes with smooth bottoms and two handles. The user sits in a crouched position inside the dish and is limited to using the handles and the shifting of body weight for steering the saucer. Steering is difficult. Moreover saucer sleds are very plain in design. Steel runner sleds typically include parallel steel skates connected to a front steering bar and a top platform. Users typically either lie on their stomachs on the platform and use their hands to steer with the steering bar or they sit on the platform and use their feet to steer. Steel runner sleds can be dangerous because of the potential for the metal skates to run-over the user or an observer. Also because of their construction, steel runner sleds are heavy, typically plain in appearance, and difficult to transport and store.
- The snow sled of the present invention includes a seat section, a body section, a handlebar arrangement, and a foot section. In some embodiments the seat section is rigidly attached to the body section; the handlebar arrangement is mounted to the body section and moveable relative thereto; and the foot section is mounted to the handlebar arrangement and moveable relative thereto. In such embodiments, the handlebar arrangement and body section connection may be configured such that when the snow sled is in a riding configuration, the foot section is positioned in front of the seat and body sections. To ride the snow sled when in the riding configuration, a user sits on the seat section, straddles the body section, places his or her feet on the foot section, and grips the upper end of the handlebar arrangement.
- The handlebar arrangement and foot section connection may also be configured such that the handlebar arrangement and foot section can be positioned adjacent the body section and foot section, respectively, providing a retracted stowable configuration. The handlebar arrangement and foot section connection may be configured such that the foot section transitions smoothly over bumps in the snow when in the riding configuration and such that the foot section nests underneath the seat section when in the stowable configuration.
