Abstract
A snowboard pole system that includes a collapsible pole and a body-mountable receiver therefor. The pole includes a user-grippable region and a snow-engaging region and selectively extends between a collapsed position and an extended position. The receiver is secured about a portion of the user's body, such as a non-articulating portion of a user's limb, and includes a pair of spaced-apart retainers, each adapted to selectively receive and retain the collapsed pole.
Description




FIELD OF THE INVENTION




The invention relates generally to snowboard poles and storage devices, and more particularly to collapsible snowboard poles and body-mountable receivers therefor.




BACKGROUND AND SUMMARY OF THE INVENTION




By way of background, a snowboard is a winter sports device that includes an elongate board on which a user's feet are retained in relatively fixed positions by a pair of spaced-apart bindings. Unlike a pair of skis, which are always pointed in the direction of the user's movement and which enable the user's feet to be moved independent of each other to propel, steer or stop the user's movement, snowboards are capable of moving across snow in a variety of directions and do not enable the user to move his or her feet once mounted on the board to propel the board. Instead, snowboards rely upon being positioned on an inclined surface to generate speed. Once moving, the user steers and stops the board by leaning and twisting his or her body and legs to generate radial and angular movement of the board as it slides down the inclined surface.




The sport of snowboarding has experienced dramatic increases in popularity in recent years, and considerable advances have been made to both the boards and the bindings that secure a user's feet thereupon. Nonetheless, there are still several problems which have not been adequately addressed. The problems are primarily centered around three areas, namely, standing up from a sitting position once the snowboarder's feet are secured within the bindings, balancing on and steering the snowboard once standing, and moving on level or uphill ground. The first two areas are most commonly encountered by beginning snowboarders, while the latter problem area is a nuisance for all snowboarders.




Beginning snowboarders often find the sport terribly frustrating because of the basic fact that snowboards slide on sloped surfaces and remain stationary on level surfaces. While this seems very simplistic, beginning snowboarders spend most of their time sitting on the snow because they have not learned how to get to a standing position once both feet are mounted on the board and/or balance and steer themselves on the board once standing.




To use a snowboard, the user places the board near the top of a run. Then, from a sitting position near the edge of the run, the snowboarder straps both feet into the board's bindings. From this position, with the snowboarder's knees bent and the snowboard oriented at an angle with respect to the ground, the snowboarder has the challenge of getting into a standing position on the board. Because of his or her lack of leverage, the snowboarder cannot get to a standing position by simply putting his or her hands on the ground and pushing upwards. Therefore, one of two methods must be used. In the first, the snowboarder grabs the front end of the board and rocks forward, dropping the bottom of the board to lie against the downslope of the run. This rolling motion and the leverage provided by grabbing the tip of the board collectively pull the user to a standing position. Although difficult to master, it is the quickest conventional way to get to a standing position, provided the user has sufficient forearm and abdominal strength to perform this maneuver.




The other alternative is for the snowboarder to flip over so that he or she is kneeling toward the ground with the board extending rearwardly behind the snowboarder. From this position, it is possible for a snowboarder to push up from the ground with his or her hands and get to a standing position on the board. Although not as quick, this basic maneuver is the most commonly used method for beginning snowboarders to get to a standing position once strapped onto the board. Although this method works, it is awkward, somewhat slow and requires the snowboarder to consistently sit and put his or her hands in the snow. Therefore, there is a need for a device that the snowboarder can use to easily get from a sitting position to a standing position on the board.




Unfortunately, this only begins the beginning user's problems. If the board is on level ground, so that it does not immediately begin sliding once the user is standing, it is possible for the user to get accustomed to the feel of standing and leaning on the board. Because the board is on a level surface, however, it does not go anywhere. Therefore, the snowboarder is forced to hop to the edge of the run or sit down, remove at least one foot from its binding, move to the edge of the run and repeat the above process. If the board is on an inclined surface, the board immediately begins sliding as soon as the user's body is off the ground. This does not, however, mean that the snowboarder is fully standing or even balanced on the board. This explains why beginning snowboarders commonly fall almost immediately after standing or attempting to do so. Therefore, there is a need for a device that may be used for balance and stability while a snowboarder learns to stand and balance upon, as well as steer and otherwise maneuver, a snowboard.




Beginning and advanced snowboarders face additional delays and hassle when they need to travel over level or upwardly inclined ground. Because almost all ski areas are designed for skiers, who can easily navigate fairly large level or inclined surfaces, this problem is fairly often encountered by snowboarders. Examples of such situations are encountered at the bottom of a run when a snowboarder needs to get to the lift, and at the top of the run when the snowboarder needs to get from the lift to the start of the desired run. When only very short, relatively flat distances need to be traveled, the common, although tiring, solution is to hop to the desired position. When this solution is not practical, the snowboarder must sit down and take at least one foot out of its binding. With one foot removed, the user can propel the snowboard much like a skateboard. Unfortunately, this one-foot-on and one-foot-off position causes a significant percentage of injuries, especially to beginning snowboarders as they try to stop and steer the board.




When longer or steeper distances must be traveled, the typical, time-consuming solution is to sit down, remove both feet from their bindings, carry the snowboard to the new spot, sit down, replace both feet in their bindings, and then perform one of the above-discussing standing maneuvers. Therefore, there is a need for a device that enables a snowboarder to propel him or herself across level or uphill ground without the effort and time required by conventional methods.




The present invention overcomes these and other problems in the form of a collapsible snowboard pole and a body-conforming receiver onto which the collapsed pole is secured when not being used. The pole includes a user-grippable region and a snow-engaging region and selectively collapses and extends between a collapsed length and an extended length. The receiver is secured on a portion of a snowboarder's limb and includes a pair of spaced-apart retainers into which the collapsed pole is selectively received and retained.




These and other advantages of the present invention will be more readily understood after a consideration of the drawings and the detailed description of the preferred embodiments which follow.

DETAILED DESCRIPTION OF THE INVENTION




The invented snowboard pole system is shown in FIG.


1


and generally indicated at


10


. System


10


includes a collapsible snowboard pole


12


and a receiver, or body-securable harness,


14


that receives the collapsed pole and retains it near the user's body. Although only one collapsed pole and receiver are shown are

FIG. 1

, it should be understood that a pair of poles and receivers would most commonly be used, one mounted on each leg or other limb of the user.




In

FIG. 1

, system


10


is shown mounted on a user's lower leg. As shown, the user's boot


16


is mounted on a snowboard


18


by a binding


20


, which is strapped about boot


16


to secure the boot (and thus the user's leg and foot) to the board in a defined orientation with respect to the board. Receiver


14


is shown mounted on the user's lower leg, where it extends generally along the leg between the user's ankle and knee. It should be understood that references made herein to the user's body or limbs include any clothing, bindings, braces, etc. between the user's actual body part and the receiver or other device mounted thereupon. Therefore, when the receiver is said to be mounted on the user's lower leg, it includes the fact that there may be clothing, binding portions, boot portions, brace portions, etc. between the user's skin and the receiver.




In

FIG. 1

, it can be seen that receiver


14


is strapped around the leg in two spaced-apart positions, one generally adjacent the user's ankle and the other just below the user's knee. It should be understood that other mounting positions are possible, including other positions on the user's limbs, such as on the user's thighs, forearms and upper arms. When selecting a suitable mounting position, receiver


14


must be mounted on the user's body in a position where it will not hinder the user's flexibility or movement, while also maintaining the collapsed pole


12


in a location where it can quickly and easily be reached, removed and remounted by the user. Other possible mounting positions include the user's back, chest and hips, as long as the above-requirements are met.




Because snowboard pole


12


is mounted on receiver


14


when the snowboarder is snowboarding down a run, receiver


14


should retain pole


12


in an out-of-the-way position where it will not be dislodged or otherwise struck by the user while snowboarding. Additionally, pole


12


must be retained on receiver


14


in a position, and with sufficient force, that pole


12


will not be dislodged while the snowboarder slides down the hill, including the jumps and tricks often seen performed by more advanced snowboarders.




As shown in

FIGS. 2 and 3

, pole


12


includes a pair of opposed end regions


22


and


24


, the first of which may be referred to as a user-grippable region, which includes a user-grippable element, such as knob


26


. Because the pole is mounted against the user's body, its user-grippable element will most commonly resemble a knob or small protrusion that is sized and shaped to fit within the palm of the user's hand, thereby minimizing size and fitting closely against the receiver or portion of the user's limb. Therefore, knob


26


preferably provides a gribbable surface without adding the significant size of the handles used with most ski poles. As shown, knob


26


includes a looped strap


28


through which the user's hand may be passed when the pole is used. Strap


28


couples the pole to the user's wrist in case the pole is unintentionally released by the user.




The other end region


24


may be referred to as a snow-engaging region and includes snow-engaging elements, such as basket


30


and tip


32


. Snow-engaging region


24


is similar to the end of a conventional ski pole, and may include any of the features commonly associated therewith. As perhaps best seen in

FIG. 2

, basket


30


is retained on pole


12


by collars


34


and


36


. The size and configuration of basket


30


may take the form of any conventional basket used with ski poles and may be selectively interchanged to enable the basket to be adjusted to best fit the conditions on any particular day.




As discussed, pole


12


is selectively extendable between a range of positions bounded by a collapsed position (shown in

FIGS. 1 and 2

) and an extended position (shown in FIG.


3


). It should be understood that pole


12


may collapse and extend between these positions via any known mechanism that provides the necessary support and strength for the application described herein. The presently preferred form is for pole


12


to be comprised of a plurality of interconnected, telescoping segments


40


-


44


, as shown in FIG.


3


. The collapsed length of pole


12


should be short enough that the pole will not interfere with the user's movement or flexibility when the pole is mounted on receiver


14


.




For example, when used by most adults, this length may range between approximately nine or more inches and approximately twenty-four or less inches, preferably is within the range of approximately twelve and approximately twenty-two inches, and even more preferably is within the range of approximately fifteen and approximately twenty inches. When the pole is built for use by shorter users, such as children, it should be understood that the collapsed and extended lengths of the pole will be decreased proportionately. Similarly, extremely tall users may require poles that are longer than twenty-four inches in length. Furthermore, the number of segments may also vary between two and four or more interconnected segments, however, three segments are presently preferred because they enable collapsed and extended lengths that meet the requirements described herein.




Adjacent segments are secured in user-selected positions with respect to each other by lock mechanisms


46


. It should be understood that any known lock mechanism for selectively retaining segments


40


-


44


with respect to each other may be used. Examples of suitable lock mechanisms include various known cam structures used in collapsible ski poles, walking sticks and golf ball retrievers that are actuated by rotating adjacent, partially overlapping segments with respect to each other. Other suitable lock mechanisms may include mechanisms used with tripods or other stands that are engaged by manipulation of a latch mounted at one end of the pole, or mechanisms used with crutches and other supports that include one or more detents and/or pushbutton mechanisms that selectively prevent the adjacent members from collapsing once extended beyond a defined location. Other suitable lock mechanisms are disclosed in U.S. Pat. Nos. 5,478,117 and 5,441,307 to Quintana et al., and U.S. Pat. No. 4,596,405 to Jones, the disclosures of which are hereby incorporated by reference. Still others are manufactured by Testrite of Newark, N.J.




When selecting a suitable lock mechanism, the mechanism must be able to selectively secure adjacent segments together even when the user's full weight is placed upon the pole. Unlike a ski pole, the invented snowboard pole is used to provide leverage and support to the user as the user rises from a sitting position to an upright position on the board. Therefore, the lock mechanism must be able to support this weight, which often times is several hundred pounds. An additional factor is that the lock mechanism should be actuable without requiring precise manipulation of the mechanism. Because the user will most commonly be wearing gloves or mittens, the user needs to be able to selectively engage and release the mechanism without removing his or her gloves or mittens. Additionally, because of the cold environment in which snowboards are typically used, the user's fingers often have less than their normal dexterity and nimbleness.




A suitable lock mechanism


46


, shown for an illustrative and non-exclusive example, is shown in

FIGS. 4 and 5

. Mechanism


46


is shown interconnecting segments


40


and


42


, which telescope and partially overlap with each other. Mechanism


46


includes a cam structure


48


that selectively locks and releases the adjacent segments as the segments are rotated with respect to each other.




In

FIG. 4

, it can be seen that cam structure


48


includes an axial member


50


, which is mounted on the end of the smaller diameter segment, namely segment


40


. Member


50


includes a base


52


, a shaft


54


of smaller diameter than segment


40


, and a top


56


. As shown, shaft


54


extends between base


52


and top


56


and is offset from the longitudinal axis of segment


40


, which is generally indicated at


58


in

FIGS. 4 and 5

. Member


50


further includes a tab


60


, which extends away from shaft


54


generally transverse to axis


58


.




Cam structure


48


further includes a collar


62


, which is mounted upon and rotatable about shaft


54


. Collar


62


has a generally cylindrical configuration and includes an aperture


64


, which is sized to enable the collar to be rotatably mounted about shaft


54


. Aperture


64


extends from the perimeter of collar


62


to define a neck region


66


, which retains the collar about shaft


54


. Extending from neck region


66


, aperture


64


includes a central passage


68


with a diameter generally corresponding to that of shaft


54


. Finally, aperture


64


terminates with a removed region


70


that extends proximate the perimeter of collar


62


opposite neck region


66


to enable collar


62


to more easily deform to mount collar


62


on shaft


54


.




As further shown in

FIGS. 4 and 6

, collar


62


defines a track


72


bounded by radially spaced-apart stops, namely a tooth


74


, adjacent one side of neck region


66


, and a support


76


that extends from the other side of neck region


66


. When collar


62


is rotated about shaft


54


, tab


60


travels within track


72


. When tab


60


engages either of stops


74


and


76


, collar


62


is prevented from rotating about shaft


54


, and the adjacent segments are either locked in a selected length or free to be telescoped with respect to each other to a shorter or longer length. As shown, central passage


68


of aperture


64


is offset from the center of collar


62


to substantially the same extent that shaft


54


is offset from the center of base


52


. In

FIG. 4

, collar


62


is shown in a first position in which collar


62


and base


52


are at least substantially superimposable along the axis of the smaller diameter segment and collectively have a maximum diameter that is less than the inner diameter of the overlapping, larger diameter of segment


42


. From the first position, collar


62


is rotatable to and from a second position (shown in FIG.


5


), in which collar


62


is rotated from the first position so that it protrudes beyond the perimeter of base


52


to give base


52


and collar


52


a collective maximum diameter that is as large as the inner diameter of segment


42


and therefore wedges, or frictionally retains, the segments at their selected combined length.




In

FIG. 4

, lock mechanism


46


is shown in its unlocked, or unbiased, position, in which the collective length of the joined segments (in this case segments


40


and


42


) is adjustable simply by extending or shortening the degree to which the segments telescope with respect to each other. As shown, tab


60


abuts the portion of support


76


distal neck region


66


, and collar


62


is in its first position, where it is substantially superimposable with base


52


. Once a desired length is selected, the segments are rotated about their long axes so that tab


60


travels to the other end of track


72


, as shown in FIG.


5


. In this position, tab


60


abuts tooth


74


and the segments are frictionally locked in the selected position by the force of collar


62


and base


52


against the inner wall of segment


42


.




It should be understood that the lock mechanism


36


connecting segments


42


and


44


operates in the same fashion described above and contains the same elements and subelements. Furthermore, to enable the user to get a better grip on the segments, the ends of segments


44


and


42


facing tip


32


include a grip


78


.




Preferably, segments


40


-


44


are prevented from becoming unintentionally detached from each other, such as if a user pulls one segment too far out of the overlapping segment. To prevent this, a portion of segments


42


and


44


proximate tip


34


include a neck region


80


of smaller diameter than the rest of the corresponding segment, and a portion of segments


40


and


42


distal tip


34


and neck region


80


include a region of larger diameter than neck region


80


. As shown for example in

FIG. 4

, neck region


80


of segment


42


is shown in dashed lines and is of smaller diameter than the rest of segment


42


, while base


52


has a larger diameter than neck region


80


and is housed within segment


42


on the opposite side of neck region


80


than tip


32


. In this configuration, base


52


acts as a stopper or plug that prevents segment


40


from being fully withdrawn out of segment


42


. It should be understood that the relative spacing of neck region


80


on segment


42


and


44


may vary, but it preferably is relatively near the end of the corresponding segment that faces tip


32


. The farther neck region


80


is away from this end, the less the length of pole


12


can be extended. Furthermore, the smaller diameter segment may include a rib or protruding portion other than base


52


.




Turning now to

FIG. 7

, receiver


14


can be seen in more detail. Receiver


14


is a pole-receiving structure that is sized to receive and retain pole


12


when the pole is in its collapsed position. Receiver


14


includes a pair of spaced-apart retainers


82


and


84


, which are each configured to selectively engage a portion of the collapsed pole and prevent it from being unintentionally removed from receiver


14


. Retainers


82


and


84


are generally aligned along the long axis of receiver


14


, along which pole


12


is mounted and supported. The retainers are supported in this position by an elongate support structure, or support,


86


, which extends therebetween. As shown, retainers


82


and


84


extend from the opposed end regions of receiver


14


, although it is within the scope of the present invention that the retainers may be mounted closer together or are adjustably mounted on the receiver.




Retainer


82


extends generally transverse to the long axis of receiver


14


and includes a projecting shelf or ledge


88


with an aperture


90


through which tip


32


of pole


12


is passed when the collapsed pole is mounted on the receiver. As perhaps best seen in

FIGS. 7 and 9

, retainer


82


and support


86


collectively form a generally L-shaped carrier for pole


12


. When tip


32


is passed through aperture


90


, pole


12


is essentially seated upon the ledge


88


because basket


30


cannot pass through aperture


90


. Retainer


82


could also be described as forming a closed, relatively rigid loop with a central passage, namely aperture


90


, extending transverse to the long axis of receiver


14


. It should be understood that the size and configuration of aperture


90


may vary, however, it should be small enough to prevent basket


30


and/or collar


34


from passing therethrough, while still being large enough to permit tip


32


to be easily inserted therein. If aperture


90


is too small, it will require the user to very carefully position tip


32


in order to insert it within aperture


90


.




Retainer


84


is adapted to receive a portion of collapsed pole


12


generally adjacent knob


26


, namely a portion of the largest diameter segment, which as shown is segment


44


. Retainer


84


includes at least one deformable member, or clip,


92


that deforms outwardly from a rest position (shown in FIG.


7


and in solid lines in

FIG. 8

) to a biased position (shown in dashed lines in

FIG. 8

) as pole


12


is inserted into or removed from engagement with retainer


84


and thereafter returns at least substantially to the rest position. As such, retainer


84


enables pole


12


to be snap-fit into and out of engagement with receiver


14


.




Returning to

FIG. 7

, it can be seen that support structure


86


includes a region


94


with a concave cross-sectional configuration measured along the long axis of receiver


14


. Preferably, region


94


has an axis of curvature that is substantially similar to the axis of curvature of largest diameter segment


44


so that it cradles or at least partially extends around segment


44


when pole


12


is mounted on receiver


14


. This relatively broad region of contact between pole


12


and region


94


stabilizes and supports pole


12


when mounted on receiver


14


.




As shown, region


94


extends from retainer


84


toward retainer


82


, but does not extend the full distance therebetween. This is because basket


30


has a larger diameter than segment


44


, and therefore would interfere with pole


12


being both inserted at least partially within aperture


90


and also being snap-fit into retainer


84


and supported along region


94


.




To further secure collapsed pole


12


upon receiver


14


, receiver


14


includes a pole-retaining strap


96


that extends from one side of receiver


14


, and a clasp or hook


98


on the other side. Preferably strap


96


is elastomeric and includes a handle portion


100


that enables strap


96


to be more easily gripped and positioned by the user, even when wearing gloves or mittens. Strap


96


is sized to be drawn from where it is mounted on one side of receiver


14


, around the portion of the collapsed pole distal support structure


96


and thereafter retained on the other end of support structure


86


by clasp


98


. As such, strap


96


and support structure


86


define a closed boundary around pole


12


in a direction transverse to the long axis of the mounted pole. Strap


96


prevents pole


12


from being unintentionally dislodged from receiver


14


under any condition.




It should be understood that the above-described retainers


82


and


84


should prevent unintentional removal of pole


12


from receiver


14


under substantially all conditions, however, strap


96


is provided for an added degree of security when the user is performing expert tricks, or when the user is not going to use the pole for a while. It should be further understood that the pole-retaining strap may include the looped structure shown in

FIG. 8

, only a single length of strap (which is secured to the clasp once extended around the portion of the pole), or a pair of strap segments, one on each side of the support structure and adapted to be secured together by any suitable fastening mechanism.




As shown in

FIG. 7

, support structure


86


is formed from first and second


102


and


104


generally planar members that are slidably adjustable with respect to each other to adjust the end-to-end length of receiver


14


. Perhaps best seen in

FIG. 9

, support structure


86


includes a plurality of spaced-apart sockets


106


extending through members


102


and


104


and generally aligned in a spaced-apart relationship between retainers


82


and


84


. Members


102


and


104


are secured in a selected position with respect to each other by any suitable fastening mechanism. For example, in

FIGS. 7 and 9

a pair of screws or bolts


108


are passed through selected sockets


106


and retained therein by nuts


110


or other suitable devices. Alternatively, sockets


106


may be threaded so that a screw can be inserted and retained therein without requiring a nut or similar device. As shown, both retainers


82


and


84


are mounted on the same member of support structure


86


, however, it is within the scope of the present invention that one retainer could be mounted on each member so that the distance between the retainers could be adjusted when the length of the receiver is adjusted.




As discussed above, retainer


14


is mounted on a portion of a user's limb. Preferably, this is a non-articulating portion (meaning between adjacent joints) so that the receiver and collapsed pole will not restrict or otherwise interfere with the user's flexibility and mobility. To secure receiver


14


to a selected limb portion, the invented snowboard pole system


10


includes strap structure


112


that extend around the user's limb to secure receiver


14


thereupon, with the long axis of support structure


86


extending generally parallel to the long axis of the limb portion. As shown in

FIG. 7

, the strap structure includes a pair of spaced-apart straps


114


and


116


, each extending from mounts


118


on a respective one of members


102


and


104


. Each strap


114


and


116


includes one or more segments that collectively extend around the portion of the user's limb. It should be understood that it is within the scope of the present invention that straps


114


and


116


may be of fixed or adjustable length and may be formed from a flexible and/or elastic material. Furthermore, when the strap includes more than one segment, it may further include any suitable fastening mechanism, such as a hook and loop closure mechanism, a buckle, a snap, etc. to join the segments together to complete the closed loop around the limb portion.




Another embodiment of the invented receiver is shown in FIG.


10


and indicated generally at


120


. Receiver


120


is similar to the above-described receiver


14


, except that its support structure


86


is not adjustable in length. Instead, it is formed from a single member, with corresponding retainers mounted proximate each end thereof. Furthermore, as shown, instead of the previously described retainer


82


, receiver


120


includes a cup-shaped retainer


122


that defines a cavity


124


into which tip


32


is inserted when pole


12


is mounted on the receiver. Retainer


122


has an open end


126


that should be sized similar to the above-described considerations with respect to aperture


90


, and a closed bottom portion


128


that prevents pole


12


from being pushed in the direction of retainer


84


if tip


32


is struck or otherwise impacted while pole


12


is mounted on the receiver. Also, receiver


120


does not include concave region


94


.




It is meant to be within the scope of the present invention that any of these elements (a fixed length receiver, a cup-shaped retainer, and no concave stabilizing region) may be selectively interchanged with the other elements of the invented receivers described herein. For example, receiver


14


may be formed with cup-shaped retainer


122


instead of retainer


82


or with a planar support


86


that does not include concave region


94


.




In

FIG. 11

, another embodiment of the invented snowboard pole system is shown and indicated generally at


130


. System


130


includes pole


132


and receiver


134


. Unless otherwise indicated, pole


132


and receiver


134


include the same elements and subelements as pole


12


and receiver


14


shown in

FIGS. 1-8

. Unlike the prior embodiments, system


130


includes a hook and loop closure mechanism


136


that further secures pole


132


on receiver


134


. As shown, mechanism


136


includes a first portion


138


that extends along region


94


of support structure


86


, and a second portion


140


that extends around segment


44


. Preferably, portion


140


extends all the way around segment


44


so that any radial mounting orientation of pole


132


on receiver


134


will engage the corresponding portions


138


and


140


of mechanism


136


, and thereby provide an additional support and retaining force on pole


132


.




It should be understood that receiver


14


may be adapted to receive and selectively retain collapsed poles of a variety of shapes and sizes. Preferably, the length (end-to-end distance) of collapsed pole


12


does not substantially exceed the similarly measured length of receiver


14


. As such, pole


12


does not substantially project above or below receiver


14


. When pole


12


has a cross-sectional configuration that is noncircular, region


94


should have a similar configuration to provide a stabilizer for the pole when mounted on the support. Alternatively, receiver


14


may be formed without stabilizing region


94


. Additionally, the axis defined between retainers


82


and


84


may diverge from being parallel to the long axis of receiver


14


to accommodate poles with larger baskets. In this case, aperture


90


of retainer


82


would be spaced further away from support structure


86


. It should be further understood that receiver


14


could be formed with or without pole-receiving strap


96


, with only a single retainer, with a pair of similar retainers, such as two retainers


84


, or with a single retainer and the above-described hook and loop fastening mechanism.




Because pole


12


is mounted generally against receiver


14


, it may be necessary to resect a portion of basket


24


when it is desirable to use a basket that would not otherwise fit between the pole's mounting position on receiver


14


and support structure


86


. Because some baskets are formed from a rigid perimeter that is secured to the pole by flexible straps, intermediate sized baskets may flex or deform to fit within the spacing requirements of receiver


14


. It should be understood, however, that it is within the scope of the present invention that all known baskets may be adapted for use with the present invention, however, larger baskets may require a portion of the basket to be removed or reshaped to enable the collapsed pole to be mounted on receiver


14


and retained proximate the user's limb portion.




To use the invented snowboard pole system, the receiver is first sized to fit the desired limb portion. When selecting the desired length, the receiver is preferably as long as possible without causing the user's flexibility of movement to be restricted by any portion of the invented system, including the receiver, strap structure, or collapsed pole. Another factor when selecting the desired length of the receiver is the position of the strap structure about the selected limb portion. For example, when mounting the receiver on the user's lower leg, as shown in

FIG. 1

, it is desirable to have the upper strap extend just below the user's knee and the lower strap to extend around the user's boot. This position provides increased stability for the system and prevents the system from sliding upward or downward during use. When a nonadjustable receiver is to be used, it should be understood that it would be available in a variety of lengths so that the user could select the appropriate length for his or her intended use.




Once the receiver is sized for the particular user, it is secured against the user's limb or other body portion by the system's strap structure. When the strap structure is adjustable, some or all of its individual segments may need to be initially adjusted to size the structure to securely retain the receiver on the user's limb without being too tight.




To mount the pole on the receiver, the user first collapses the pole to its collapsed, shortest position by manipulating the pole's lock mechanism or mechanisms. When a lock mechanism with the above-described cam structure is used, this is accomplished by rotating the adjacent segments of the poles to position the lock mechanism in an unlocked or unbiased position, collapsing the segments to their shortest collective length, and then rotating the segments in the opposite direction to lock the mechanism and retain the segments in the collapsed position. Once adjusted to be in its collapsed position, the tip of the pole is inserted within the aperture or cavity of retainer


82


or


132


, and then the upper portion of the pole is snap-fit into retainer


84


. In this position, the retainers collectively should be able to retain the pole on the receiver under almost all situations, including when the user crashes and when the user lands (or attempts to land) from a jump. When increased support is desired, or when the user is not going to use the pole for a while, the pole-retaining strap may be secured about the pole to prevent unintentional removal of the pole under any conditions.




It should be understood that the above process will most commonly be repeated to mount another snowboard pole system on another selected limb portion, such as the corresponding other leg or arm portion.




From a sitting position in the snow with the user's feet mounted on the board, the user can now grab the pole or poles, urge the upper portion away from retainer


84


to release the snap-fit and then remove the tip from the other retainer. Once removed, the collapsed pole can be extended to a desired extended position. Typically, this is between two and one half and four feet, and it is intended that poles may have maximum extended lengths within this range in one or two inch increments. The extended poles can then be used to provide the necessary leverage for the user to get to a standing position on the board without having to undergo the tiring or inconvenient processes previously required. It should be understood that the pole may provide sufficient leverage for the user in its collapsed or an intermediate position.




Once standing, with the poles in their extended position, they can be used to stabilize the user on the board and stop any movement caused by the force of the standing process. This is particularly appropriate for beginning snowboarders who require extra stability and support until they become comfortable steering, stopping and maneuvering the snowboard. The poles can also be used to propel the user to a desired position, regardless of whether the position is far away from the user or uphill from the user's current position. Once positioned at the top of a run, the poles can be quickly shortened to their collapsed positions and remounted on their respective receivers. Then the user simply tips forward or slightly hops forward onto the downslope of the run, where the user snowboards down the run. Beginning users may wish to keep the poles in an extended position to provide stability and support as they learn to snowboard.




At the bottom of the run, the poles can be removed from the receiver, extended and then used to propel the user to the lift or tow line. Even if the user has to stop and slowly move forward in the line (for example if there are many skiers and snowboarders waiting in line), the poles can be used to propel, stabilize and stop the user. Any snowboarder should understand from the above that the invented snowboard pole system significantly reduces the time and hassle required to get from the bottom of a run, to and through the lift line and back to the start of a selected run. Instead of having to stop at the bottom of the run, sit down, remove at least one foot from its bindings, awkwardly move to and through the lift line, be carried up the hill with only one foot strapped to the board (thereby putting considerable strain on the ankle of that foot), get off the lift and try to balance or even steer with only one foot secured to the board, move to a desired position, sit down, refasten the removed foot, etc., the user can maintain both feet within their bindings at all times and therefore can steer and maneuver the board at all times. Furthermore, the board can be propelled and stopped without requiring removal of one or both feet from their bindings.




While the invention has been disclosed in its preferred form, it is to be understood that the specific embodiment thereof as disclosed and illustrated herein is not to be considered in a limiting sense as numerous variations are possible and that no single feature, function or property of the preferred embodiment is essential. The invention is to be defined by the scope of the issued claims.
