摘要:
The present invention is a sled for use by a person on snow. The sled comprises a low profile body member comprising an upper portion and a bottom portion adapted slide upon the snow. The upper portion comprises a front portion and a rear portion. The rear portion comprises a seat portion adapted for seating by the person. The sled further comprises a low profile rudder member moveably engaged with the rear portion. The low profile rudder member has a handle portion and a snow engagement portion adapted to be in contact with the snow. In operation, the person may grip and move the handle portion thereby causing movement of the snow engagement portion.

A skateboard with a handlebar has a board member connected to a support rod from a front end. The handlebar is connected to a top end of the support rod for permitting direction of the skateboard to be changed. A front blade is pivoted to a lower end of the support rod, and a rear blade is pivoted to a rear lower part of the board member for permitting the skateboard to be moved along on ice. The blades can be replaced with shaped skis for permitting the skateboard to be moved along on snow. The skateboard further has a brake depressable to move the rear blade downwards for a stopping block on a bottom of the rear blade to contact the ice. The skis have stopping trenches on a bottom; the trenches do not touch the ground normally, but do when the skateboard leans sideways.

An ice board including a platform for supporting an individual in a standing or crouched position, a pair of single in line ice runners disposed below and fixed to the platform, and a brake member, a first or forward ice runner defines a curved ice engaging surface which curves upwardly toward the front of the platform while the rear ice runner includes a flat ice engaging surface over about 80 percent of its length. The rear ice runner also includes a curved surface at the rear thereof for rotating the front of a platform upwardly and for bringing the brake member into engagement with the ice to slow or stop momentum of the ice board on the ice.

A steering ski for a snowmobile comprises a ski body and a reinforcing member. The steering ski has a flat portion for contacting the surface of the ground and an upturned leading portion. The reinforcing member is connected to the upturned leading portion at multiple connection points. The ski and the reinforcing member are coupled to transmit forces in a way that reduces the pressure in the upturned leading portion. The forces are applied to the ski when the snowmobile strikes obstructions in its path and when it lands after becoming airborne. A stopper is provided to transmit the forces.
摘要:
A skag for a ski, such as a vehicle ski. The skag includes a carrier platform to be attached to the bottom surface of a ski. First and second longitudinal rails are disposed on the lower surface of the carrier platform. The longitudinal rails are spaced apart laterally from one another. First and second longitudinal keels are disposed on the first and second rails, respectively. At least a portion of the first rail may extend beyond the first lateral edge of the carrier platform, and at least a portion of the second rail may extend beyond the second lateral edge of the carrier platform. The back ends of the rails may be shaped so as to be flush against the carrier platform, or to have some other shape that at least partially fills in the grooves left by the keels. The skag may be made to have a unitary structure, as by welding the components thereof together to form a single piece.

The bicycle has a frame on which a front wheel and a rear wheel are rotatably mounted. At least one of these two wheels is connected to at least one device using wind-generated Bernouilli force to assist forward motion of the bicycle. Such device has a wind-driven turbine with a plurality of horizontal air foils attached to a shaft rotatably mounted about a horizontal axis. It also has a shield positioned adjacent to part of the turbine to deflect wind and prevent it from impacting the air foils when they rotate forwardly. A clutch is operatively connected to the shaft of the turbine to the wheel for transferring the force generated by the wind within the turbine to this wheel.
摘要:
Reinforcement element made of a composite material constituted of a layer of inextensible textile material and a layer of polymeric material assembled to the layer of textile material during a molding or vulcanizing step. The textile material is a woven or mesh material, and the textile material is a polyester, polyamide, polypropylene or glass fiber based material. The polymeric material can be a thermosetting material, such as rubber or silicone, or an injected thermoplastic, such as polyurethane, polyvinyl chloride, or polypropylene. Advantageously, the polymeric material is at least partially transparent. The composite material can be incorporated in a boot or a binding using tightening straps. The invention also relates to a method of manufacturing such reinforcement element.

A snowboard and rotatable mount securing a binding thereon are provided. The mount includes a base member affixed to the snowboard by fasteners extending through positioning holes. A coupling member is rotatably disposed in the base member and includes openings to fasten the binding to it. A latch operates to lock and unlock the rotation of the coupling member so that the rider may orient the boot with respect to the board's longitudinal axis. When locked, the boot's longitudinal axis is generally transverse to the board's longitudinal axis in a primary boot position. When unlocked, the rider can rotate the boot so that its longitudinal axis is generally parallel to the board's longitudinal axis in a secondary boot position. A snowboard having first and second bindings is provided with the mount's coupling member attached to the second binding. A method for supporting a binding on a snowboard is also provided.
摘要:
A walking snowboard that enables its user to walk over snow cross-country and also to surf down slopes. A shared floating-tongue (20) comprising vinyl rollers and wheels is located in and along over half the length of framed chambers beneath a deck (10). The snowboard with its split body rolls easily over the shared floating-tongue as a user walks. The shared floating-tongue interconnects with the two sides of the walking snowboard's body.

A steering ski for a snowmobile is disclosed. The steering ski comprises a ski body and a wear bar connected to a ski bracket. The ski bracket is used to attach the ski to the balance of the snowmobile. The ski body also receives a reinforcing member that reinforces a portion of the ski body which is curved upwardly. Reinforcing ribs travel along the length of the ski body on an upper portion of the ski body. The sole of the ski body or lower surface includes a keel that expand in width from a forward-most portion and then decreases in width rearward of a juncture between a snow contacting portion of the ski body and the upwardly-extending portion of the ski body. A wear bar is positioned along the keel and depends below a lowermost portion of the keel rearward of the widest portion of the keel. The wear bar extends into the ski body through a forward aperture and a rearward aperture. The rearward aperture is sized and configured to allow ice chips to be passed through the ski body and slung upward to cool various components of the snowmobile.
