Description




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.

DESCRIPTION OF THE INVENTION




Referring to the drawings and particularly to

FIGS. 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 releasably interconnecting the foot enclosure assembly with the support base. Support base


14


includes an upper surface


14




a


and a lower surface


14




b


and, in the form of the invention shown in

FIGS. 1 and 2

, comprises a snow-board. As best seen in

FIGS. 3 and 4

, the upper surface


14




a


of support base


14


is provided with a pair of spaced-apart, generally circular shaped recesses


17


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 Palencia, Calif. 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

FIG. 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


(FIGS.


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

FIG. 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 (FIG.


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

FIGS. 14 and 15

, the release means here comprises a guide frame


27


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


(

FIG. 14

) within which a release plate


36


is telescopically movable from the first upper position shown in

FIG. 11

to the second, release position shown in FIG.


14


. Rear plate


38


is provided with a vertically extending, elongated guide slot


40


(FIG.


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

FIG. 11

to the release position shown in

FIG. 14

, guide pin


42


moves from a position proximate the upper extremity of guide slot


42


(

FIG. 11

) to a second position proximate the lower extremity of the guide slot


40


(FIG.


14


).




In the embodiment of the invention shown in the drawings, release plate


36


is controllably moved from the uppermost position shown in

FIG. 11

to the release position shown in

FIG. 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 FIG.


15


. As shown in

FIG. 13

, bosses


52


extend through aligned openings


54


provided in side walls


30


of FIG.


26


. With this constrtuction, a handle assembly


56


can be used to pivot cam member


50


from the position shown in

FIG. 11

to the release position shown in FIG.


14


. Handle assembly


56


of the character best seen in FIG.


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


58




a


which is connected to bosses


52


of cam member


50


by suitable connectors such as a set screw


59


(FIG.


15


). The opposite, or out board end


58




b


of each of the arm


58


is connected to a two-part handle member


60


comprising portions


60




a


and


60




b


. When portions


60




a


and


60




b


are interconnected in the manner shown in

FIG. 10

the handle member can be grasped by the user in a manner to move the handle assembly from the position shown in

FIG. 11

to the upward release position shown in FIG.


14


. As shown in

FIGS. 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


36




a


thereof to move into pressural engagement with the upper surface


14




a


of the support base. As the handle assembly is urged upwardly in the manner shown in

FIGS. 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

FIGS. 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

FIGS. 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


64




b


. Upper surface


63




a


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 assembly 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

FIGS. 1 through 15

, like numerals are used in

FIG. 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

FIGS. 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

FIGS. 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

FIGS. 1 through 18

and like numerals are used in

FIGS. 19 through 23

to identify like components. The major difference between the apparatus of the invention shown in

FIGS. 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

FIGS. 19 and 20

, the g&ripping 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

FIG. 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 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

FIG. 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

FIGS. 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 ulser'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

FIGS. 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


84




a


of the support base which surface is spaced apart from the lower surface


84




b


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


89




a


thereof by any suitable means such as adhesive bonding (FIG.


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

FIGS. 26 and 27

, connector frame


86


is of a generally barbell-like configuration and is securely affixed to the upper surface


84




a


of support


84


by connector pins


97


. As indicated in

FIGS. 26 and 31

, second magnets


88


are slidably mounted within the oval shaped openings


87


for movement between a first position shown in

FIG. 26

wherein the second magnets are in index with the first magnets


92


to a second position shown in

FIG. 31

wherein the second magnets are displaced from the first magnets (see also FIG.


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 designated 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

FIGS. 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

FIG. 31

, wherein the second magnets are displaced from and misaligned with the first magnets.




This important displacement mechanism


100


of the invention here comnprises 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

FIGS. 27 and 30

, driven member


102


includes a conventional pinion gear


106


and a generally elliptically shaped head portion


108


which is connected to gear


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


112




a


for engagement with pinion gear


106


in the manner shown in

FIGS. 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


(FIG.


30


). As indicated in

FIGS. 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

FIG. 26

, rotation of finger gripping head


114


will cause pinion gear


106


along with elliptical head


108


, to rotate into the transversely extending position shown in FIG.


31


. In the present form of the invention the connector links have their inboard ends connected to ends


108




a


of elliptical head portion


108


and their outboard ends connected to second magnets


88


in the manner shown in

FIGS. 26 and 29

. With this construction, movement of shaft


112


and elliptical head portion


108


into the second position shown in

FIG. 31

will cause second magnets


88


to slide within oval shaped openings


87


toward the second displaced position shown in FIG.


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

FIGS. 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 FIG.


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 FIG.


33


. More particularly, rather than rotating elliptical-shaped member


108


by means of the finger engaging wheel and gear arrangement shown in

FIGS. 24 through 32

, member


108


can be rotated by a linkage mechanism


117


of the character shown in FIG.


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 pivotally connected to an arm


123
