Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




The present invention relates to a removable strap for a snowboard boot to prevent the rider's foot from lifting in the boot, and an ankle strap for use in a snowboard boot or binding.




2. Description of Related Art




Snowboarding has become increasingly popular as a recreational sport. A snowboard typically includes bindings that attach the rider's feet to the board. Three main types of bindings have been developed.




A first type of binding is adapted to be used with a hard boot, which is similar to an alpine ski boot. Typically, the boot includes a hard plastic molded shell, and is securely mounted on the board via a plate binding that includes rear and forward bails that engage the boot. Hard boots provide support for the rider's foot, in that a properly sized boot will not allow the rider's foot to move therein, and will typically prevent the heel from lifting from the bottom of the boot.




A second type of binding is adapted for use with a soft boot, which, as the name suggests, is at least partially made of a softer material than hard boots. The typical binding used for soft boots has a rigid high back piece into which the heel of the boot is placed, and one or more straps that secure the boot to the binding. Such bindings can be somewhat inconvenient to use because after each run, the rider must unbuckle each strap to release the boot when getting on the chair lift, and must re-buckle each strap before the next run.




A third type of binding that has recently been developed for use with a soft boot eliminates the need for binding straps and provides the convenience of a step-in system. An example of such a binding system is disclosed in currently pending U.S. patent application Ser. No. 08/584,053, entitled METHOD AND APPARATUS FOR INTERFACING A SNOWBOARD BOOT TO A BINDING, filed Jan. 8, 1996 and assigned to Burton Snowboards. Soft boot step-in bindings are more convenient than conventional strap bindings, making it easier to engage and disengage the rider's boots from the board.




The development of soft boot step-in binding systems has presented a problem not previously encountered. In particular, tremendous lifting forces are generated at the feet of a snowboard rider. It is desirable to prevent the rider's foot, particularly the heel, from lifting from the bottom of the boot to maximize control. In a hard boot plate binding system, the boot is generally sufficiently rigid to hold the rider's foot down and prevent lift. Similarly, in a conventional soft boot strap binding system, the straps are tightened down over the boot and hold the rider's foot down to prevent lift. However, with a strap-less soft boot step-in binding, only the laces of the boot are available to resist lifting, which is often insufficient. Accordingly, it is an object of the present invention to prevent lifting of the rider's foot in a strap-less soft boot step-in binding system.




U.S. Pat. No. 5,435,080 (Meiselman) discloses a strap system for preventing lift in a snowboard boot that is a hybrid of a hard and soft boot. The Meiselman boot has a hard lower portion that is adapted to engage a plate binding and a soft upper portion. In one embodiment the Meiselman boot has a heel strap fixed thereto to prevent heel lift. In another, heel and toe straps are fixed to the boot.




Although the Meiselman straps are said to be effective in preventing lift, they are not used in connection with a soft boot and would suffer a significant disadvantage if they were. In particular, it is desirable for soft boots to be usable with not only the more recently developed step-in binding systems, but also with the more conventional strap bindings. The Meiselman boot is not suited for use with a strap binding system, because the straps fixed thereto would overlap and interfere with the binding straps. Accordingly, it is a further object of the present invention to provide a snowboard boot that prevents lifting of the rider's foot when used in conjunction with a strap-less binding system, but is also compatible with a strap binding.




Straps, whether on a boot or binding, can create uncomfortable pressure points on the rider's foot when tightened. Additionally, if a strap is too wide, it may not conform to the contour of a rider's foot, which can cause the foot to become cramped or pinched in various locations. Accordingly, it is another object of the present invention is to provide a strap that securely fits over a snowboard boot while not creating uncomfortable pressure points.




SUMMARY OF THE INVENTION




In one illustrative embodiment of the present invention, an apparatus is provided that comprises a snowboard boot and a strap that is removably attached thereto and arranged to prevent a rider's foot from lifting in the snowboard boot. In one aspect of this embodiment, the strap is arranged to prevent the rider's heel from lifting in the boot. In another aspect of this embodiment, the snowboard boot has a lateral side and a medial side, and the strap is removably attached at a first location at a first location on the lateral side and a second location on the medial side of the snowboard boot. A buckle may be attached to the strap to adjust the tension in the strap. In another aspect of the invention, the strap may be attached to the boot at first, second and third attachment locations. The first and second attachment locations may be disposed on the medial side of the boot and the third attachment location may be disposed on the lateral side of the boot. Further, the strap may be constructed so that the strap does not apply pressure to the instep bone of the rider.




The present invention also provides a snowboard binding for releasably securing a snowboard boot that includes a strap which is adapted to releasably secure the snowboard boot, the strap being constructed and arranged to avoid the creation of a pressure point at an instep bone of a rider. The strap further may be arranged to prevent a heel of a snowboard boot from lifting from the binding. Additionally, the boot may include a base having a lateral side and a medial side and the strap may be attached at a first location at the lateral side and a second location at the medial side. The strap may have an opening that is positioned to be disposed above the instep bone of the rider. In another aspect of the invention, the strap may be attached to the base at a first, second and third attachment locations, wherein the first and second attachment locations are disposed on the medial side of the binding, and the third attachment location is disposed on the lateral side of the binding. Additionally, the strap attached at three attachment locations may have a Y-shape.

DETAILED DESCRIPTION OF ILLUSTRATIVE EMBODIMENTS OF THE INVENTION




In one illustrative embodiment of the present invention, a strap is provided to hold a rider's heel against the bottom of a snowboard boot.

FIG. 1

illustrates one application for this embodiment of the invention, i.e., a soft snowboard boot used with a strap-less step-in binding system. In

FIG. 1

, the ankle strap


30


is attached to a snowboard boot


32


, which is in turn mounted to a snowboard


34


by a binding suggested at


36


. As discussed above, the strap is advantageous because it keeps the rider's heel from lifting in the boot, thereby maximizing the rider's maneuverability and control. The strap is constructed to keep the heel seated in the boot even during hard turns and aggressive high-performance maneuvers.




In one embodiment of the invention, the strap is removably attached to the boot in any number of ways as described below. Thus, the strap


30


can be attached when used with a strap-less binding to hold down the rider's foot, and can be removed to enable the boot to be used with a strap binding.





FIG. 2



a


illustrates an exemplary boot


32


with a two-point connection strap


30


(only the medial side is shown)in accordance with the present invention attached at location


38


on the boot. Although the strap


30


shown in

FIG. 2



a


has two attachment points, it should be understood that the invention is not so limited, and that a plurality of attachment points can be provided on each side of the boot. The boot


32


shown in

FIG. 2



a


includes an interface


44


, as disclosed in application serial no. 08/584,053, for engaging a step-in binding. However, it should be understood that this invention is not limited to the illustrative construction, and that other arrangements for cooperating with a step-in binding may be employed on the boot.




The boot shown in

FIG. 2



a


has a rubber sole


40


to provide traction. The portions


42


of the binding interface at the medial and lateral portions of the sole (only the medial side is shown in

FIG. 2



a


) allow the boot to be securely engaged by the binding. The boot shown also includes a high-back support


46


that provides leverage in assisting the rider in getting on his or her heel edge. The upper portion of the boot


48


is formed from a soft material (e.g. leather or synthetic material), and is laced up the front in a conventional manner by laces


52


.




In the embodiment shown in

FIG. 2



a


, the strap is attached to the boot at the molded interface


44


. This is advantageous because the interface is sufficiently strong to secure the strap. However, as described below, the strap can alternatively be attached to other portions of the boot, including the soft upper section, and is not limited to use with a boot including a molded interface.




The ankle strap


30


of

FIG. 2



a


need not be as strong as a strap used in a conventional soft boot strap binding because the boot is secured to the board by the engagement between the step-in binding and the binding interface


42


, not the strap


30


. The ankle strap only prevents the heel from lifting in the boot. Thus, a relatively thin strap


30


can be used which provides the advantage of having a low-profile and non-bulky appearance that is integrated with the boot.





FIG. 3



a


illustrates a sectional view of the strap


30


of

FIG. 2



a


. The strap may have a load bearing component made from a suitable non-stretch material that will not stretch significantly even when wet. Examples of such materials include a Kevlar or fiberglass band encased in a plastic coating such as Surlyn (available from DuPont), a non-stretch plastic strap formed by injection or compression molding, and a laminated non-stretch fabric die-cut to a desired shape. In the embodiment shown, the strap


30


includes a non-load bearing component. For example, the strap


30


may include a cushion material


54


(e.g., EVA foam material) to increase comfort. The cushion material may be covered with a polypropylene skin so that it does not absorb moisture, and may be disposed entirely around the strap. It should be understood that although the cushion material increases comfort, it is not required.




A second non-load bearing component such as strap piece


56


may be overlaid and attached to the outer surface of the strap


30


for decorative purposes. The second piece may be made from leather so that the strap looks integrated with the boot. Additionally, a shaggy leather piece


58


may be attached to the strap piece


56


, and the strap may be provided with a debossed insignia as illustrated.




It should be understood that snowboard boots are provided in many different sizes. As mentioned above, it is desirable to integrate the strap of the present invention with the boot. However, it is also preferable to avoid the necessity of providing a differently sized strap customized for each boot size. Therefore, in one embodiment of the invention, the strap is adjustable so that the strap can be used with several boots of different sizes.




An example of an adjustable strap


30


is illustrated in

FIG. 3



b


. The location


43


on the strap


30


that is attached to the boot


32


(schematically shown in phantom) can be adjusted. As described in more detail below with reference to

FIGS. 7



a


and


7




b


, the strap can be attached to the boot with a screw


130


that is fastened to the boot through a hole in the strap. Several holes


45


may be provided so that the most desirable fit for the strap can be selected. After the strap is adjusted to the desired fit, an excess amount of the strap


30


, as suggested by dotted line


31


, may be removed so that it does not extend over the end of the board. The adjustable feature of the present invention enables each strap to be used with multiple boot sizes so that the number strap sizes (e.g., four or five) can be less than the full line of boot sizes (e.g., ranging from sizes 3-13).




As shown in

FIG. 2



a


, the heel strap


30


is connected at attachment locations


38


(only one is shown in

FIG. 2



a


) on the boot. The placement of the attachment locations


38


can impact the performance of the strap in holding down the heel, and the rider's comfort. The placement that will maximize performance and comfort will vary depending on the rider's personal preference. The height of the attachment point above the heel and the distance forward from the heel will both impact the comfort and performance of the strap. In general, the lower and further back the attachment locations are for the strap of

FIG. 2



a


, the greater the holding force.





FIG. 2



b


illustrates a zone of possible attachment points for the strap, represented by solid line


41


. The area bounded by line


41


is approximately a quarter circle having a center disposed 2 cm up from the bottom of the sole and forward of the heel at approximately 10% of the length of the boot. The radius of the quarter circle is approximately 12 cm, although this will vary with the size of the boot. While not intended to be exclusive, it is believed that attachment points within this zone will provide satisfactory performance for the strap of the present invention. As shown in

FIG. 2



b


, the attachment zone has a lower boundary that is approximately 2 cm from the bottom of the sole. The lower boundary is selected so that the attachment location does not interfere with the interface between the boot and the binding.





FIG. 2



b


also illustrates a preferred attachment zone, illustrated by shaded region


39


. The preferred zone also has a lower boundary that is 2 cm from the sole bottom, and an upper boundary that is 10 cm from the sole bottom. The upper boundary is selected so that sufficient forces may be applied to hold the heel in the boot. The distance of the strap attachment point forward from the heel also affects performance. As shown in

FIG. 2



b


, the preferred attachment zone


39


extends forward from the heel by approximately 10-35% of the total boot length. Although the attachment zones shown in

FIG. 2



b


are believed to provide satisfactory performance, it should be understood that the present invention is not limited to attachment points within these zones. Furthermore, the configuration and width of the strap will also affect the location of the most comfortable attachment point.




Various prototypes of the strap of

FIG. 2



a


have been constructed and tested. The table below lists several trial configurations used with a size 9.5 boot.

In one embodiment of the invention, shown in

FIG. 2



a


, a second strap


66


is located in a region forward of the metatarsus. The strap


66


holds the forward part of the foot in the boot so that when the rider's weight shifts toward the heel, the toes do not pull upward away from the boot bottom. As with the strap


30


, strap


66


may be attached to the interface


44


or to any other portion of the boot. The strap


66


can be constructed in the same manner as strap


30


, and is removable in the same manner. Although the use of the two straps


30


and


66


provides the advantages discussed above, it should be understood that the invention does not require the use of two straps.




The strap of the present invention may include a buckle or other adjustable fastening mechanism for allowing selective tightening and loosening of the strap. The strap may include a first strap portion disposed on one side of the foot and a second portion on the other, with a buckle or some other type of mating mechanism adapted to releasably secure the two strap portions.

FIG. 4

shows an illustrative example of such a strap


70


. The strap includes a first portion


71


that includes a plurality of transverse protrusions or teeth


74


extending upwardly therefrom. The strap further includes a second portion attached on the opposite side of the boot and including a buckle


72


adapted to releasably engage the teeth


72


of the strap portion


71


. The buckle pivots relative to the second strap portion about a pin


73


. To tighten the strap


70


, the buckle is pivoted to an open position and the strap portion


71


is fed into the buckle until the desired tooth


74


is engaged therewith. The buckle is then rotated in the direction of arrow A (

FIG. 4

) to tighten down the strap.




The above-described buckle arrangement provides several advantages. First, the plurality of teeth


74


provides a level of adjustability that enables each strap to be used with boots of different sizes, which is advantageous for reasons discussed above. Second, the buckle provides a convenient mechanism for adjusting the tension on the strap. For example, when it is desired to temporarily release the tension of the strap on the rider's foot (e.g., when riding up on the lift), the buckle can be rotated to the open position without having to alter the fine positional adjustment established by the selection of a particular one of the teeth


74


for engaging the buckle.




In an alternate embodiment of the invention, the mechanism for tightening and loosening the strap is a slap-ratchet as described in U.S. Pat. No. 5,416,952, assigned to Burton Snowboards, which is incorporated herein by reference. In this embodiment, the strap


70


also has the plurality of teeth


74


that engage corresponding ratchet teeth in the slap ratchet to secure the strap at the desired tension.





FIG. 5



a


illustrates another aspect of the present invention wherein an ankle strap


90


is provided that secures the heel of the rider and includes means for avoiding the creation of a pressure point on the rider's instep bones (the internal cuneiform bone being the most prominent). This is achieved in the embodiment of the invention shown in

FIG. 5



a


with a Y-shaped strap


90


that includes two branches


92


and


94


connected on the in-step side of the boot. The branches


92


and


94


merge at a branch


96


(shown in phantom as unsecured) that is attached on the other side (not shown) of the boot. Thus, the strap can be formed from a single piece of any of the materials discussed above as being appropriate for forming the strap of

FIG. 2



a


, and can also include the cushioning and decorative features discussed above. The branch


96


includes a plurality of teeth


98


that are similar to the teeth


74


(FIG.


4


) discussed above, and can be used to secure the strap to a buckle or slap rachet in the same manner as the strap


70


(FIG.


4


).




In the embodiment shown in

FIG. 5



a


, the Y-shaped strap


90


holds the rider's heel in the boot while spreading the force applied to the rider's foot. Thus, the strap does not create a pressure point at the instep bones of the rider. The location of the branches and the space created between them impacts the comfort of the strap. In the embodiment shown, the Y-shaped strap has one branch higher on the foot than the tarsal-metatarsal junction (proximate the location where the ankle bends), and the other branch lower on the metatarsal region. This configuration is advantageous because it avoids creating a pressure point on the instep bones. However, it should be understood that the present invention is not limited to the arrangement shown in the drawings, and that other arrangements are possible. For example, the strap can have two attachment points on both sides of the boot, or can have a single attachment point on each side with a cut-out region above the instep bones. Also, the fixation mechanisms (e.g., the buckle and mating teeth) can be reversed between branches


92


and


94


and branch


96


.




The locations where the branches


92


,


94


and


96


are attached to the boot can impact the comfort and performance of the strap


90


. One example of a set of attachment locations is as follows: the strap branch


92


can be connected at a location


112


that is 7.5 cm from the heel and 3.7 cm from the bottom of the sole; the strap branch


94


can be connected at a location


114


that is 15.7 cm from the heel and 2.5 cm from the bottom of the sole; and the strap branch


96


can be connected at a location that is 4.5 cm from the heel and 4.5 cm from the bottom of the sole.





FIG. 5



b


illustrates another embodiment of a Y-shaped strap


102


according to the present invention. In this embodiment, branches


104


and


106


are formed from a single piece of non-stretchable material. The branches form a teardrop-shaped opening therebetween that accommodates the top of the rider's foot. A strip


110


connects the strap on the other side of the boot. The materials used may be any of those discussed above in connection with the strap of

FIG. 2



a.






The pressure relieving strap of the present invention has several applications. The strap can be attached to a snowboard boot as described above to hold down the rider's heel. In this respect, the strap can be removably attached to provide the advantages described above. However, the pressure relieving strap can alternatively be permanently fixed to the boot and would still provide advantages in terms of comfort over a prior art system such as disclosed in Meiselman. Furthermore, the pressure relieving strap can be used in any application wherein a strap is used to engage a boot or foot, such as on a soft boot strap binding.





FIG. 6

illustrates a soft boot binding


116


that employs a Y-shaped strap


117


according to the present invention. The strap


117


has two connection points


118


on the medial side of the binding, and a single connection point


119


on the lateral side. A buckle or slap ratchet arrangement (not shown) may be used on the strap, and can be attached on the lateral side.




As discussed above, in one embodiment of the invention, a strap is removably attached to a snowboard boot so that the boot can be used either with a soft boot step-in binding or a more conventional strap binding. Many different types of strap and boot junctions can be used to make the strap removable, and that the present invention is not limited to any particular one. However, solely for the purpose of illustration,

FIGS. 7-11

depict a number of different junctions for detachably connecting the strap to the boot.





FIG. 7



a


is a cross-sectional view of a first arrangement for attaching the strap to a boot. This arrangement includes a screw


124


that passes through the strap and is received by a T-nut


126


(shown in a top view in

FIG. 7



b


) mounted through the boot to secure the strap


120


thereto. The T-nut may be mounted through the interface


44


(

FIG. 2



a


), the upper boot


48


, or any other portion of the boot that has sufficient “pull-though” strength to prevent the T-nut from being pulled through the boot when the strap is tensioned. The T-nut has internal threads


127


disposed along a central opening to receive external threads


128


on the screw, and can be anchored to the boot (e.g., by sharp protrusions


125


that engage the boot, by heat welding, or by glue) so that it does not rotate when the screw is tightened or loosened. The strap is secured to the boot by placing the screw


124


through a hole in one end of the strap, and tightening the screw into the T-nut to tightly secure the strap. The strap can be removed simply by loosening the screw. Thus, the screw securely holds the strap to the boot while enabling easy removal and re-attachment. The insert and screw of

FIGS. 7



a


-


7




b


are sized so that the overall length of the attachment is minimized, and to ensure that the attachment does not protrude significantly from the surface of the boot. The screw


124


can also have a flat head


130


, and a slot


132


sized so that a small coin can be used to tighten/loosen the screw so that a screwdriver is unnecessary. Of course, any other type of screw can also be used.





FIGS. 8



a


,


8




b


, and


8




c


illustrate another embodiment of a connector that can be used to attach the strap to the boot. In this embodiment, a key-type fastener is used. An example of a suitable key-type fastener is available under the Trademark DZUS. As shown in

FIGS. 8



a


and


8




b


, the fastener includes a key


202


and a lock


204


that is attached to the boot. The key


202


has a shaft


206


with a protrusion


208


extending radially therefrom, and a semicircular handle


210


that enables the key to be held and turned as desired. The lock


204


is a substantially flat circular piece having an interior cavity


212


as illustrated in

FIG. 8



c


. The lock


204


has central opening


214


that is sized to receive the key shaft


206


. The central opening has a cut out


216


shaped to receive the protrusion


208


of the key such that the key will only be received in the lock when the protrusion


208


is oriented with the cut out


216


. Once within the lock, the key may be turned to secure the key in the lock. The key-type fastener can be used to secure the strap to the boot by disposing the lock


204


on the boot in a desired attachment location. The key shaft is passed through a hole in the strap so that when the key is secured within the lock, the strap is secured at the desired location.





FIG. 9



a


illustrates a schematic view of another type of connection between the strap and boot. In this embodiment, the boot


170


(shown in phantom) has a molded binding interface


172


that includes slots


174


and


176


for receiving the strap. While the slots are shown as being curved, they can also be straight. The long direction of the slots can be angled with respect to the sole of the boot as illustrated. The strap


178


, shown partially in phantom, is passed into one slot and out the other so that an intermediate piece


180


of the boot holds the strap in place. The free end


182


of the strap can be attached to the boot to secure the strap. Alternatively, the strap can be secured by doubling it back on itself as shown in

FIG. 9



c


, which illustrates the free end


182


doubled back and attached to the strap


178


. The free end can be attached to the strap in any number of ways, e.g., with snaps or with hook and loop fasteners.





FIG. 9



b


illustrates a further alternate arrangement wherein a hook


186


is attached to the end of the strap


178


to secure the strap to a slot such as


174


or


176


in the boot. The hook is configured to correspond to the slot to facilitate entry and may be made of a suitable rigid or semi-rigid plastic material. Multiple slots can be employed to enable the effective length of the strap to be adjusted.





FIG. 10

illustrates another embodiment for attaching the strap to the boot. In this embodiment, a passage


190


is formed through the boot so that a strap


194


, shown in phantom, may extend under the rider's foot through the passage


190
