Description: APPARATUS FOR GLIDING OVER SNOW S P E C I F I C A T I O N Background of the Invention 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. 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. Patent 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. Patent 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. Patent 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 aforementioned 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.

Description of the Invention Referring to the drawings and particularly to Figures 1 through 7, one form of the apparatus of the invention for gliding over snow is there shown. In this form of the invention, there are three principal cooperating components, namely, a support base 14, a foot enclosure assembly 16, and release means connected to the foot enclosure assembly for re- leasably interconnecting the foot enclosure assembly with the support base. Support base 14 includes an upper surface 14a and a lower surface 14b and, in the form of the invention shown in Figures 1 and 2, comprises a snow-board. As best seen in Figures 3 and 4, the upper surface 14a of support base 14 is provided with a pair of spaced-apart. generally circular shaped recesses 16 within which is mounted a generally circular shaped magnet 18. Magnets 18 are of a high holding power, compact design, and can be constructed from various materials. By way of example, magnets 18 can comprise powerful ceramic ring, permanent magnets which are readily commercially available from various sources including A-L- L Magnetics, Inc. of Valencia, California. These ceramic magnets can be constructed in various configurations and, if desired, can be encased in nickel-plated steel cups. Magnets 18 are commercially available in a number of different sizes and range in diameter from about 2 inches to about 5 inches. The larger of these magnets exhibit holding power of on the order of 200 pounds per magnet. It is to be understood that in constructing the apparatus of the present invention, a single relatively large magnet can be used, or in the alternative, a plurality of smaller magnets disposed in a suitable array can be used to provide the magnetic forces necessary to releasably secure the foot enclosure assembly of the apparatus to the support base. By way of example a snow-board of a nominal length will require one magnet per foot enclosure with a pulling strength of about 150 pounds per magnet. This will achieve a total pulling strength of 300 pounds. The average weight of a person using a snow-board will typically be about 150 pounds. The magnets will then have double the pulling strength of the weight to be held in the desired position on the snow-board. Referring to Figure 5, the foot enclosure assembly 16 of the present invention can be seen to comprise a snow boot-like foot enclosure 20 and a first metal plate 22 which is affixed to the lower surface of the snow boot 20 by any suitable means such as rivets 23 (Figures 6 and 7). Plate 22 may be constructed from any suitable rigid metal which is capable of being attracted by the magnets 18 which are interconnected with the support base 14 by adhesive bonding or any other suitable means. Also forming a part of the foot enclosure assembly of the invention is a second plate 24 which is pivotally connected to plate 22 for very limited movement of a few degrees about a pivot pin 26. More particularly, as shown in Figure 5, plate 24 extends upwardly from plate 22 and normally is disposed generally perpendicularly with respect thereto. Plate 24 functions to provide support to the heel portion of the foot enclosure 20, but permits slight forward movement through a limited distance of X (Figure 5). However, plate 24 positively resists rearward angular movement of the rear portion of the boot and lower leg of the user. The distance X can, of course, vary depending upon the physical stature of the user, but generally is on the order of about 1 inch. This movement is sufficient to permit the skier or snow boarder to comfortably lean forward in the binding but, at the same time, provides support against rearward angular leaning movement relative to plane of the support base. Forming an important feature of the apparatus of the present invention is the release means for releasing the foot enclosure assembly from the support base. As best seen by referring to Figures 14 and 15. the release means here comprises a guide frame 26 which includes a rear plate 28 that is securely affixed to plate 24 of the foot enclosure assembly. Protruding rearwardly from plate 28 are a pair of transversely spaced-apart side members 30 and a top closure plate 32. Spaced-apart sides 30, along with a back wall or rear plate 38, cooperate to define a guideway 34 (Figure 14) within which a release plate 36 is telescopi- cally movable from the first upper position shown in Figure 1 1 to the second, release position shown in Figure 14. Rear plate 38 is provided with a vertically extending, elongated guide slot 40 (Figure 13), which guides the vertical travel of a guide pin 42 which is affixed to release plate 36. With this construction, as release plate 36 moves from the first position shown in Figure 11 to the release position shown in Figure 14. guide pin 42 moves from a position proximate the upper extremity of guide slot 42 (Figure 11 ) to a second position proximate the lower extremity of the guide slot 40 (Figure 14). In the embodiment of the invention shown in the drawings, release plate 36 is con- trollably moved from the uppermost position shown in Figure 11 to the release position shown in Figure 14 by operating means which here comprises as a cam assembly 48. Cam assembly 48 includes a cam member 50 having outwardly extending bosses 52 which are affixed at either side of the cam member in the manner shown in Figure 15. As shown in Figure 13, bosses 52 extend through aligned openings 54 provided in side walls 30 of Figure 26. With this construction, a handle assembly 56 can be used to pivot cam member 50 from the position shown in Figure 11 to the release position shown in Figure 14. Handle assembly 56 of the character best seen in Figure 15. As there shown, handle assembly 56 includes two spaced-apart side arms 58, each of which terminates at its upper end in a generally annular shaped connector 58a which is connected to bosses 52 of cam member 50 by suitable connectors such as a set screw 59 (Figure 15). The opposite, or out board end 58b of each of the arm 58 is connected to a two-part handle member 60 comprising portions 60a and 60b. When portions 60a and 60b are interconnected in the manner shown in Figure 10 the handle member can be grasped by the user in a manner to move the handle assembly from the position shown in Figure 11 to the upward release position shown in Figure 14. As shown in Figures 11 and 14. as the handle assembly is pivoted upwardly, release plate 36 will be forced downwardly by cam member 50 causing the lower extremity 36a thereof to move into pressural engagement with the upper surface 14a of the support base. As the handle assembly is urged upwardly in the manner shown in Figures 12 and 14, release plate 36 will be urged downwardly so that plate 22 will be separated from the magnet 18 thereby breaking the magnetic attraction and allowing separation of the foot enclosure assembly from the support base. Following separation of the foot enclosure assembly from the base plate, the handle assembly is, of course, pivoted downwardly into the starting position so that the foot enclosure assembly can, at such time as is desired, be reconnected to the base plate by superimposing plate 22 over a selected one of the magnets 18. Turning next to Figures 16 through 18. an alternate form of the apparatus of the present invention for gliding over snow is there shown. This apparatus is similar in many respects to the apparatus shown in Figures 1 through 15. However, in this latest form of the invention the support base, rather than being a snow-board, comprises a ski 63 of a generally conventional configuration. Ski 63 has an upper surface 63 a, and a lower snow engaging surface 64b. Upper surface 63a is provided with a generally rectangular shaped cavity 65 within which is affixed permanent magnet 67. Magnet 67 is of the same character as the magnets 18 previously discussed herein and is preferably constructed from a powerful magnetizable ceramic or metal material. Once again, magnet 67 should be designed to apply a force of approximately 150 pounds on the metal plate of the foot enclosure assem- bly which is identical to that previously described. Because the foot enclosure assembly, as well as the release means of this second apparatus of the apparatus is identical to that described in connection with Figure 1 through 15, like numerals are used in Figure 16 to identify like components of the foot enclosure assembly and release means. It is to be understood that when two skis are used, each ski is of the general construction shown in Figures 16 and 17 with each ski being provided with a magnet receiving cavity 65 and an appropriately powerful permanent magnet 67 embedded therewithin. Use of the release means of the invention to release the foot enclosure assembly from the ski is accomplished in the same manner as previously described herein. Turning to Figures 19 through 23, still another alternate form of the apparatus of the invention is there shown. This apparatus is similar in many respects to that illustrated in Figures 1 through 18 and like numerals are used in Figures 19 through 23 to identify like components. The major difference between the apparatus of the invention shown in Figures 19 through 23 and the earlier-described embodiments of the invention resides in the provision of anti-slip gripping means on the first metal base plates of the foot enclosure assemblies and on the magnets which are affixed to the support base of the apparatus. As best seen by referring to Figures 19 and 20, the gripping means provided on the metal base plates of each of the foot enclosure assemblies of the invention here comprises a multiplicity of downwardly extending, generally conically shaped, spike-like protuberances 70. Protuberances 70 extend downwardly from the central portion of metal base plate 72 of the foot enclosure assemblies of this latest form of the invention and as indicated in Figure 23. are generally conical in shape. Also forming a part of the gripping means of this latest form of the apparatus of the invention are a multiplicity of generally conically-shaped cavities 74 which are formed in magnet 76 of this latest form of the invention. Depressions, or cavities 74, are of the 10 same general size and configuration as conically shaped protuberances 70 so that when the foot enclosure assemblies are mated with the magnets, protuberances 70 will be received within cavities 74 so as to prevent slippage between metal plate 72 of the foot enclosure assemblies and magnets 76 which are affixed to support base 14. As best seen in Figure 21 in this latest form of the invention, magnets 76 are generally rectangular in shape and are suitably secured within rectangularly shaped cavities 78 formed in the support bases. It is to be understood that protuberances 70 can be of a number of different shapes. For example, the protuberances can comprise spaced-apart downwardly extending ribs which can be received within mating grooves provided in the magnets or, alternatively, they could be generally hub-like in shape and be received within socket-like cavities provided in the magnets. In any case, so long as the protuberances when received in mating cavities formed in the magnet function to prevent slippage between the foot enclosure assemblies and the magnets, their precise configuration is unimportant. In a similar fashion, the gripping means of the invention could comprise cooperating side frames provided on the foot enclosure assemblies and the magnet or support base to resist sliding movement of the foot enclosure assemblies relative to the support base. Referring next to Figures 24 through 32. yet another form of the apparatus of the invention for gliding over snow is there shown and generally designated by the numeral 82. This form of the invention is similar in some respects to the earlier described embodiments and like numbers are used to identify like components. In this latest embodiment of the invention there are four principal cooperating components, namely, a support base 84, a foot enclosure means for enclosing the user ' s foot, connector means for releasably connecting the foot enclosure means to the connector means and release means for releasing the foot enclosure means from the connector means. As best seen in Figures 24, 26 and 27, the connector means of the invention includes a connector frame 86 that is provided with a pair of spaced-apart, generally oval shaped recesses 87 within which generally circular shaped second magnets 88 are slidably mounted. As before, magnets 88 are of a high holding power, compact design, and can be constructed from various materials of the character previously described herein. Connector frame 86 is connected to the upper surface 84a of the support base which surface is spaced apart from the lower surface 84b that is adapted to glide over the snow. The foot enclosure means of the invention comprises a foot enclosure assembly 90, which includes a snow boot 89 having a pair of magnets 92 affixed to the sole 89a thereof by any suitable means such as adhesive bonding (Figure 24). Preferably the magnets are received within a pair of generally circular shaped cavities 94 formed in the sole of the boot 90 and are secured in place therewithin by a suitable epoxy resin. Forming an important aspect of the apparatus of this latest form of the invention is the previously mentioned connector means for releasably connecting the foot enclosure assembly 90 to the support base 84. As best seen by referring to Figures 26 and 27, connector frame 86 is of a generally barbell-like configuration and is securely affixed to the upper surface 84a of support 84 by connector pins 97. As indicated in Figures 26 and 31. second magnets 88 are slidably mounted within the oval shaped openings 87 for movement between a first position shown in Figure 26 wherein the second magnets are in index with the first magnets 92 to a second position shown in Figure 31 wherein the second magnets are displaced from the first magnets (see also Figure 27). Forming another extremely important aspect of the apparatus of the present invention is release means for disconnecting the foot enclosure assembly 90 from the connector means. In this latest embodiment of the invention, this important release means includes displacement means for controllably displacing second magnets 88 with respect to first magnets 92. This novel displacement means here comprises a displacement mechanism generally desig- 12 nated in the drawings by the numeral 100. Displacement mechanism 100 is operably associated with frame 86 for controllably sliding second magnets 88 within oval-shaped openings 87 from the first position shown in figures 26 and 27, wherein the magnets are substantially aligned with the first magnets disposed within the boot of the enclosure means to a second position shown in Figure 31 , wherein the second magnets are displaced from and misaligned " with the first magnets. This important displacement mechanism 100 of the invention here comprises a driven member 102 which is rotatably connected to frame 86 for rotation between a first and a second position. Operably associated with driven member 102 is a driving member 104. As best seen in Figures 27 and 30. driven member 102 includes a conventional pinion gear 106 and a generally elliptically shaped head portion 108 which is connected to hear 106. Also forming a part of the displacement mechanism of the invention is a pair of connector links 110 which function to interconnect driven member 102 with second magnets 88. In the manner presently to be described, connector links 110 function to controllably move the second magnets within oval shaped guide openings 87 between the first and second positions upon rotation of the driven member 102 by the driving member 104. In the present form of the invention, the driving member includes a rotatable shaft 112 having a rack portion 112a for engagement with pinion gear 106 in the manner shown in Figures 26, 29 and 30 and a finger gripping head portion 114 for gripping by the user of the apparatus to impart rotation to shaft 112 and to pinion gear 106 which is rotatable with a stub shaft 107 carried by frame 86 (Figure 30). As indicated in Figures 26 and 30, shaft 112 is of a length such that finger gripping head 114 extends outwardly from frame 86 to enable easy rotation by the user of the apparatus. In operating the unique displacement means of the invention, with head portion 108 of driven member 102 in the longitudinally extending position shown in Figure 26, rotation of 13 finger gripping head 114 will cause pinion gear 106 along with elliptical head 108, to rotate into the transversely extending position shown in Figure 31. In the present form of the invention the connector links have their inboard ends connected to ends 108a of elliptical head portion 108 and their outboard ends connected to second magnets 88 in the manner shown in Figures 26 and 29. With this construction, movement of shaft 107 and elliptical head portion 108 into the second position shown in Figure 31 will cause second magnets 88 to slide within oval shaped openings 87 toward the second displaced position shown in Figure 31. It is apparent that as the second magnets are moved inwardly within oval shaped openings 87, they will move out of alignment with magnets 92 and as the second magnets become progressively more misaligned with the first magnets 92, the holding strength of the cooperating magnets will decrease. Accordingly, the displacement means can be used to controllably adjust the holding power of the magnets and, in turn, the force with which the foot enclosure means is secured to the connector means and to support 84. It is also apparent from a study of Figures 26 and 31 that as the second magnets reach their second innermost position, the gripping power between magnets 88 and 92 will lessen to such and extend that the foot enclosure means can be easily separated from the connector means and from support 84 in the manner shown in Figure 32. Accordingly, the novel release means of the invention not only permits adjustment of the holding power of the magnets, it also permits the controlled release of the foot enclosure means from the connector frame. It is to be understood that various mechanisms of a character well understood by those skilled in the art could be used to accomplish a sliding movement of magnets 88 within oval shaped openings 87. By way of example and not by way of limitation, magnets 88 could be moved from the first to the second position by displacement means comprising a linkage mechanism of the character illustrated in Figure 33. More particularly, rather than rotating elliptical-shaped member 108 by means of the finger engaging wheel and gear arrangement 14 shown in Figures 24 through 32, member 108 can be rotated by a linkage mechanism 117 of the character shown in Figure 33. In this instance the linkage mechanism is carried by a connector frame 119 which is of a slightly different construction and includes a pivot pin 121 to which a driving member of linkage arm 123 is connected. A second linkage arm 125 is piv- otally connected to a rim 123 and to member 108 so that a movement of arm 123 from the position shown in the sold lines of Figure 33 to a position shown in the phantom lines will rotate member 108 into the release position. Other similar mechanical arrangements well known by those skilled in the art could be used to accomplish the movement of elliptical head portion 108. Having now described the invention in detail in accordance with the requirements of the patent statutes, those skilled in this art will have no difficulty in making changes and modifications in the individual parts or their relative assembly in order to meet specific requirements or conditions. Such changes and modifications may be made without departing from the scope and spirit of the invention, as set forth in the following claims. 15
