Abstract
An active high back system is provided for automatically adjusting the snowboard boot between a walking position and a riding position. The snowboard boot is provided with an active highback support that is adjustably mounted to a snowboard boot. During walking, the active highback support does not constrain the flexibility of the snowboard boot making it possible for the snowboard rider to walk easily. When the rider steps into the bindings of the snowboard, the active highback support engages a part of the snowboard or binding that causes the snowboard boot to lean forward. In other words, the highback support is positioned to engage the back leg portion of a snowboard boot to provide a rigid surface that holds the boot in a forward leaning position. The active highback support is provided with an adjustment mechanism that allows the rider to adjust the amount of forward lean when the snowboard boot is engaged within the bindings of the snow board.
Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




This invention generally relates to a snowboard boot with a highback support. More specifically, the present invention relates to a snowboard boot with a highback support that is easily adjustable.




2. Background Information




In recent years, snowboarding has become a very popular winter sport. In fact, snowboarding was also an Olympic event during the winter games at Nagano, Japan. Snowboarding is similar to skiing in that a rider rides down a snow covered hill. The snowboard is generally shaped as a small surfboard or a large skateboard without wheels. The snowboarder stands on the snowboard with his or her feet generally transverse to the longitudinal axis of the snowboard. Similar to skiing, the snowboarder wears special boots, which are fixedly secured to the snowboard by a binding mechanism. In other words, unlike skiing, the snowboarder has both feet securely attached to a single snowboard with one foot positioned in front of the other foot. The snowboarder stands with both feet on the snowboard in a direction generally transverse to the longitudinal axis of the snowboard. Moreover, unlike skiing, the snowboarder does not utilize poles.




Snowboarding is a sport that involves balance and control of movement. When steering on a downhill slope, the snowboarder leans in various directions in order to control the direction of the movement of the snowboard. Specifically, as the snowboarder leans, his or her movements must be transmitted from the boots worn by the rider to the snowboard in order to maintain control of the snowboard. For example, when a snowboarder leans backward, the movement causes the snowboard to tilt accordingly turning in the direction of the lean. Similarly leaning forward causes the board to tilt in a corresponding manner and thus causing the snowboard to turn in that direction.




Generally, the sport may be divided into alpine and freestyle snowboarding. In alpine snowboarding, hard boots similar to those conventionally used for alpine skiing are worn, and fitted into so-called hard bindings mounted on the snowboard, which resemble alpine ski boot bindings. In freestyle snowboarding, soft boots similar to ordinary boots, or adaptations of such boots as distinct from hard shell alpine boots are typically worn, fitted into so-called soft bindings.




Boots that are used for, for instance, skiing and/or snowboarding must have a high degree of rigidity for effecting steering while skiing and snowboarding. In particular, when snowboarding it is important that the rider be able to lean to the side, back and forward with respect to the snowboard. The motion corresponding to the direction of the lean of the rider is transmitted through the boots to the snowboard (or skis) to effect turning or braking. Therefore, it is extremely important that the boots worn by the rider have sufficient rigidity to transfer such leaning motion to the snowboard or skis.




In particular, the back side of a snowboard boot must be rigid in order to provide the appropriate support for controlling movement of the snowboard. Further, as the art of snowboarding has developed, riders have found that snowboard boots provide optimal support when the back side of the snowboard boots are inclined slightly, such that the knees of the rider are always slightly bent when wearing the boots on level ground. Therefore, standing up straight with knees straight when wearing inclined snowboard boots is not always comfortable. Further, walking in such snowboard boots is sometimes awkward.




Recently, snowboard boots have been developed which allow a rider to adjust and change the inclination of inclined backside snowboard boots. For example, there are snowboard boots which include a member known as a highback support that is secured to the snowboard boot by pins which allow the highback support to pivot about the pins. The highback support extends up the back side of the boot and when locked into position fixes the back side of the boot into a predetermined inclined position that is optimal for snowboarding. When unlocked, the highback support can pivot back and allow the rider wearing the boot to stand up straight and walk more freely without having to keep the knees bent. A simple bar is used with such a boot for locking the highback support in place. Typically, the bar braces the highback support into position. An upper end of the bar is fixed to an upper portion of the highback support by a pivot pin. A lower end of the bar is configured to fit into a hook formed in a lower portion of the boot. When a rider is wearing the boots, the rider must lean forward in order to fit the bar into and out of position. The lean forward requires a significant amount of effort due to the overall rigidity of the snowboard boots and therefore the bar configuration, especially in the snow and cold can be difficult for some riders to release and/or engage.




In view of the above, there exists a need for an improved highback system, which automatically moves from a walking position to a riding position when coupled to the binding. This invention addresses this need in the prior art as well as other needs, which will become apparent to those skilled in the art from this disclosure.




SUMMARY OF THE INVENTION




One object of the present invention is to provide a highback system that automatically moves from a walking position to a riding position when coupled to the binding.




Another object of the present invention is to provide a highback system that can be easily adjusted from a first leaning position to a second steeper leaning position without tools.




Another object of the present invention is to provide a highback support of a snowboard boot with an adjusting mechanism that is easy to manipulate.




Another object of the present invention is to provide a highback support for a snowboard boot with a reliable adjusting mechanism for controlling the amount of lean by the highback support.




In accordance with one aspect of the present invention, a snowboard boot is provided with an active highback system. The snowboard boot has a boot body with a sole portion, a toe portion, a heel portion and a leg portion. The leg portion is constructed of a flexible first material. The active highback system has a highback support movably coupled to the boot body to apply a bending force to the leg portion in a direction generally extending from the heel portion towards the toe portion. The active highback support includes a substantially rigid support member, a coupling member coupled to the support member and an adjusting mechanism. The support member engages the leg portion to apply the bending force to the leg portion. The coupling member is coupled to the support member and adapted to engage a complimentary coupling member that is separate from the snowboard boot to automatically move the support member to apply the bending force to the leg portion when engaged therewith. The adjusting mechanism is coupled between the support member and the leg portion to vary the bending force applied to the leg portion by the support member.




Preferably, an activating member is coupled to the binding and the support member is configured to be permanently fixed to a portion of a snowboard boot.




These and other objects, features, aspects and advantages of the present invention will become apparent to those skilled in the art from the following detailed description, which, taken in conjunction with the annexed drawings, discloses preferred embodiments of the present invention,

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS




Initially referring to

FIGS. 1 and 2

, a snowboard boot


10


is illustrated as being attached to a snowboard


12


with an active highback system


14


coupled therebetween in accordance with one embodiment of the present invention. Active highback system


14


is designed to allow the snowboard boot


10


to be automatically adjusted from a walking position to a riding position upon snowboard boot


10


being attached to snowboard


12


. More specifically, active highback system


14


does not constrain the flexibility of snowboard boot


10


making it possible for the snowboard rider to walk easily when the snowboard boot


10


is not coupled to snowboard


12


. When the rider steps into the binding


16


of the snowboard


12


, the active highback system


14


automatically causes the snowboard boot


10


to lean forward. In other words, the active highback system


14


engages the rear of the snowboard boot


10


to provide a rigid surface that holds the snowboard boot


10


in a forward lean position. Moreover, active highback system


14


allows the rider to automatically increase the amount of forward lean of the snowboard boot


10


by merely leaning forward.




Snowboard boot


10


basically includes a sole portion


20


and an upper portion


22


that are fixedly coupled together. Typically, the sole portion


20


is made of a stiff rubber-like material. The upper portion


22


, on the other hand, can be made from a variety of materials such as plastic materials, leather and/or synthetic leather materials. Upper portion


22


should be somewhat flexible so that active highback system


14


can apply a forward leaning force thereto. Upper portion


22


basically includes a toe portion


24


, a heel portion


26


and a leg portion


28


. These three portions


24


,


26


and


28


form a boot body that is coupled to sole portion


20


.




As seen in

FIG. 4

, sole portion


20


is preferably provided with a front cleat or engagement member


30


and a rear cleat or engagement member


32


. Cleats


30


and


32


are configured for engagement with binding


16


that is fixedly coupled to snowboard


12


in a conventional manner. The binding


16


and cleats


30


and


32


of the illustrated embodiment are of the type known as a CLICKERâ„¢ mechanism manufactured by Shimano Inc. of Osaka, Japan. Of course, it will be apparent to those skilled in the art from this disclosure that other types of bindings can be utilized for attaching snowboard boot


10


to snowboard


12


. Since the particular structure of binding


16


is not critical to the present invention, binding


16


and its cleats


30


and


32


will not be discussed or illustrated in detail herein.




As seen in

FIGS. 1

,


2


and


5


-


7


, active highback system


14


basically includes an activating member


40


coupled with binding


16


, and an adjustable highback support


42


coupled to snowboard boot


10


. The inclination or amount of lean of snowboard boot


10


is automatically adjusted between a walking position and a riding position simply by stepping into and out of binding


16


. In other words, when the rider steps into binding


16


, highback support


42


engages activating member


40


to cause the leg portion


28


of the snowboard boot


10


to lean forward towards the toe portion


24


as seen in

FIGS. 6 and 7

. When the snowboard boot


10


is released from binding


16


, activating member


40


and highback support


42


separate to allow leg portion


28


to flex without requiring any adjustment by the rider. Accordingly, active highback system


14


provides a quick and simple boot adjustment without the need of any complicated locking mechanisms.




As best seen in

FIGS. 2 and 5

, activating member


40


basically includes a first part


44


that is adjustably coupled to binding


16


, and a second part


46


extending upwardly from first part


44


for engagement with highback support


42


. First part


44


should be adjustable relative to binding


16


to accommodate various sizes of snowboard boots. Any type of adjustment mechanism can be utilized. While activating member


40


is illustrated as being adjustably coupled to the binding


16


by a slot and bolt arrangement in

FIG. 2

, it will be apparent to those skilled in the art from this disclosure that activating member


40


can be coupled to the snowboard


12


if needed and/or desired.




Second part


46


has a free end with a coupling member


48


formed thereon. Coupling member


48


is designed to engage a portion of highback support


42


, as explained below, via a quick and simple snap-type of fit. Activating member


40


and coupling member


48


form a snap-type of lock arrangement which holds the bottom end of highback support


42


in a fixed position, and forces leg portion


28


to a forward leaning position. In the illustrated embodiment, coupling member


48


has a transverse recess or groove that mates with a complimentary part of highback support


42


.




Preferably, first and second parts


44


and


46


are constructed of a rigid material such as a hard non-flexible, metallic material such as steel. Of course, other rigid materials can be used such as a hard plastic material.




Support


42


basically includes a U-shaped bracket


50


coupled to leg portion


28


of snowboard boot


10


, a lever


52


pivotally coupled to bracket


50


, and a substantially rigid support member


54


coupled to the leg portion


28


of upper portion


22


via pin


56


.




Bracket


50


is a U-shaped member constructed of a hard rigid material such as steel. Bracket


50


has a center section


60


and a pair of end sections


62


extending substantially perpendicular from center section


60


. Each of the end sections


62


is fastened to leg portion


28


of snowboard boot


10


via a fastener such as a rivet. A pivot pin


64


connects end sections


62


together. Lever


52


is pivotally coupled on pivot pin


64


.




Lever


52


preferably has a release portion


66


and a tooth portion


68


that engages support member


54


to hold support member


54


in a set position. Lever


52


is urged against support member


54


by a biasing member


70


. Biasing member


70


is preferably a torsion-type spring. Biasing member


70


has its coiled portion mounted on pivot pin


64


. A first end of the spring engages center section


60


of bracket


50


, while a second end of spring engages a part of lever


52


. Thus, lever


52


is normally biased against support member


54


to lock it in one of a plurality of predetermined leaning positions.




Support member


54


is preferably an elongated member having a first end with a plurality of notches or teeth


72


, and a second end with a coupling member


74


. A longitudinally extending slot


76


is formed between teeth


72


and coupling member


74


. Slot


76


receives pin


56


therein such that pin


56


slidably retains support member


54


on the rear side of heel portion


26


and leg portion


28


. Accordingly, support member


54


can be moved vertically along the rear of snowboard boot


10


. The vertical movement of support member


54


relative to snowboard boot


10


is controlled by lever


52


which selectively engages one of the notches or teeth


72


. While only four teeth


72


are illustrated, it will be apparent to those skilled in the art that more or fewer teeth can be utilized depending upon the amount of adjustment needed and/or desired.




Lever


52


and notches or teeth


72


of support member


54


form an adjusting mechanism to provide a plurality of leaning positions. This adjusting mechanism is a one-way clutch. Preferably, the one-way clutch is a ratchet-type of adjusting mechanism that prevents support member


54


from freely moving upwardly passed lever


52


but allows support member


54


to move freely downwardly passed lever


52


. More specifically, the rider can automatically increase the amount of forward lean by merely leaning forward when the snowboard boot


10


is properly engaged in binding


16


and coupling member


74


is engaged with coupling member


48


of activating member


40


. More specifically, by leaning forward in snowboard boot


10


, the rider causes leg portion


28


to pull bracket


50


and lever


52


upwardly along, support member


54


. This relative movement causes lever


52


to be biased against the force of biasing member


70


and engaged the next notch or tooth


72


. Support member


54


is prevented from moving upwardly with bracket


50


and lever


52


because coupling member


48


is coupled with activating member


40


.




Coupling member


74


is illustrated in the form of a protrusion


80


and a curved ramping surface


82


. Curved ramping surface


82


is designed to engage a complimentary ramping surface


49


of activating member


40


during engagement of snowboard boot


10


with binding


16


. Once the snowboard boot


10


is completely inserted into binding


16


, protrusion


80


of coupling member


74


will engage the recess of activating member


40


. This latching or coupling causes the stiff rigid support member


54


to apply a bending force on leg portion


28


. Thus, leg portion


28


is bent or leaned forward towards the toe portion


24


.




If the rider desires less lean, the rider merely pivots lever


52


against the force of biasing member


70


such that its tooth portion


68


becomes disengaged from teeth


72


of support member


54


. Then the rider merely needs to lean back until the desired amount of lean is obtained and release the lever


52


so that the tooth portion


68


re-engages one of the notches or teeth


72


of the support member.

128


. Accordingly, support member


154


can be moved vertically along the rear of snowboard boot


110


. The vertical movement of support member


154


relative to snowboard boot


110


is limited by adjusting mechanism


162


.




Lever


165


and ratchet teeth


164


form an adjusting mechanism


162


to provide a plurality of leaning positions. Each adjusting mechanism


162


is a one-way clutch. Preferably, the one-way clutch is a ratchet-type of adjusting mechanism that prevents leg portion


128


from freely moving rearwardly, but allows leg portion


128


to move freely forwardly. More specifically, the rider can automatically increase the amount of forward lean by merely leaning forward when the snowboard boot


110


is properly engaged in binding


16


and coupling member


174


is engaged with coupling member


148


of activating member


140


. More specifically, by leaning forward in snowboard boot


110


, the rider causes leg portion


128


to pull support


142


forward. This forward movement results in a pivoting action between activating member


140


and support


142


. This relative pivoting movement causes lever


165


to be biased against the force of biasing member


170


and engaged the next notch or tooth of ratchet teeth


164


.




Coupling member


174


is illustrated in the form of a protrusion. Once the snowboard boot


110


is completely inserted into binding


16


, protrusion or coupling member


174


will engage the recess


149


of activating member


140


. This latching or coupling causes the stiff rigid support member


154


to apply a bending force on leg portion


128


. Thus, leg portion


128


is bent or leaned forward towards the toe portion


124


.




If the rider desires less lean, the rider merely pivots lever


165


against the force of biasing member


170


such that its tooth portion


168


becomes disengaged from teeth


164


of support member


154


. Then, the rider merely needs to lean back until the desired amount of lean is obtained and release the lever


165


so that the tooth portion


168


re-engages one of the notches or teeth of ratchet teeth


164


.
