ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates generally to a winter sport apparatus. More particularly, the invention concerns a novel winter sport apparatus for gliding over snow which includes unique snow boots which are removably connected to a snow engaging support base such as a snow-board or ski board through the use of magnets.
2. Discussion of the Prior Art
In recent years snow sports have continually increased in popularity. While, for many years snow skiing was the sport of choice among winter sport enthusiasts, recently, the sport of snow-boarding has catapulted into popularity particularly among young persons.
With the increase in popularity of snow boarding has come the demand for better and easier-to-use equipment. Particularly in demand is the need for superior boots and bindings. As a general rule, the boots and bindings used for snow boarding are the same as used for snow skiing and closely resemble those which have been used for over fifty years. Typically, the bindings comprise rather heavy, bulky frames which are affixed to the upper surface of the snow-board with the boots being affixed to the frames by conventional types of straps, buckles and wires of the character used in snow skiing. These type of bindings are generally cumbersome, difficult to use and often fail to provide a type of interconnection between the boots and the snow-board which is essential to the sport of snow boarding.
Among the more recent improvements in snow sport bindings are those described in U.S. Pat. No. 5,558,355 issued to Henry. The Henry patent describes a binding which is particularly suitable for snow boarding and provides an easy-to-use, kick-in boot engagement feature and a number of convenient ways to disengage the boot in a relative small, light-weight, and economical structure. Another type of ski binding is disclosed in U.S. Pat. No. 5,143,397 issued to Stepanek et al. This patent describes a part for a ski binding comprising a carriage slidably attached to a base plate. One end of the base plate is fastened to the ski with fasteners while the other end rests freely on the bottom of a U-shaped clamp also fastened to the ski with fasteners. Attachment of the carriage to the base is accomplished by carriage structural features that retain the carriage in the clamp and further carriage structural features that prevent the carriage from being vertically disengaged from the part of the base adjacent to the base plate fastened end.
Still another improved binding for a snow-board is that described in U.S. Pat. No. 5,143,369 issued to Shaanan et al. The Shaanan et al patent concerns a binding for a snow-board that has a base, side members extending upwardly and rearwardly from the sides of the base with an arcuate member joining the rear ends of the side members. Fastening means on one of the side members and one side edge of the board at the front provide for attachment of one end of two straps. Fastening means on the other side member and on the other side edge serve for attachment of a locking bar which, in turn, connects the other end of each strap to the side member and base.
The foregoing prior art patents represent some of the more recent attempts to improve the quality of snow boots and bindings particularly for use in connection with snow boarding. While the devices disclosed in the aforementioned patents constitute substantial improvements over the prior art, they nevertheless remain somewhat complicated, bulky and difficult to use.
The thrust of the present invention is to overcome the drawbacks of the prior art snow-ski and snow-board boots and bindings and to provide a universal boot and binding which is easy to use and enables the quick and positive interconnection of the snow boots with the upper surface of the ski or snow-board.
SUMMARY OF THE INVENTION
It is an object of the present invention to provide a universal snow boot and binding for use in connection with either snow skiing or snow boarding which is easy to use and provides quick, easy and positive interconnection of the snow boot with the upper surface of the ski or snow-board. More particularly, it is an object of the invention to provide a highly novel snow boot and binding in which only magnetic forces are used to affix the snow boot to the ski or snow-board.
Another object of the invention is to provide an apparatus of the character described in the preceding paragraphs which is light-weight, is simple to manufacture and install, and is virtually fail-safe in operation.
Another object of the invention is to provide an apparatus of the afore-mentioned character which includes novel means for quickly and easily disconnecting the snow boot from the upper surface of the snow-board or snow ski which carries the magnetic elements of the apparatus.
Another object of the invention is to provide an apparatus as described in the preceding paragraph in which the release mechanism comprises an easy-to-use, hand-operated lever which enables the skier or the snow-boarder to quickly and easily disconnect the snow boot from the upper surface of the ski or snow-board.
Another object of the invention is to provide cooperating gripping means on the snow boot and the magnet to prevent accidental slippage of the snow boot relative to the magnet.
Another object of the invention is to provide a novel ski boot and cooperating binding which is compact, lightweight and of a simple, straight forward construction that and can be inexpensively manufactured.
