Abstract
A device is introduced that can be readily adapted to connect any two objects together, including the footwear members of a variety of different recreational or sporting devices in a manner that permits the objects or footwear members to be first attached, release, and then reconnect with each other. The invention is particularly applicable to the sport of snowboarding as it relates to the sport of skateboarding. In a preferred embodiment of the invention, the connecting device is comprised of at least two specially shaped angled bars that are able to slide and lock together. A means to secure the two angled bars together is provided by a connection between a coupling mechanism on one of the bars and a corresponding coupling block on the other angled bar. In addition, there is also a device known as the release enabler that functions to safely monitor the operation of the coupling mechanism. With the release enabler a user can select from either an open or closed position for the connecting device. The open position allows the two angled bars to completely separate and then reattach to each other while the closed position prohibits the two bars from separating (unless they are acted upon by a predetermined amount of force that has been selected by the snowboard rider).
Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




This invention relates in general to a device for connecting one object to another object, and, more specifically, to a device that can be readily adapted to connect footwear members to several types of common recreational or sporting apparatuses.




2. Description of the Related Art




There are many situations where it is desirable to have one object coupled to another object in a manner that allows the objects to attach, unconnect, and then reengage with each other. For example, there are many sporting activities where a connection like the one just described could be employed. The sports that would benefit most from the current invention are those that involve a participant's feet being linked to a separate sporting apparatus. With these types of activities, the user's feet are usually supported by some sort of footwear member, such as a shoe or boot that has been specially designed for the individual requirements of each sport. Examples of such activities include water and snow skiing, several types of skating, and snowboarding.




The present invention is particularly applicable to the sport of snowboarding as it relates to the sport of skateboarding. Snowboarding is very similar to skateboarding and a large number of people who snowboard also ride or have ridden skateboards. Many of the tricks or maneuvers found in the sport of snowboarding are directly based on tricks that are performed on skateboards. For those who ride skateboards there has always been a desire to execute the same type of maneuvers on their snowboards as on their skateboards, but not all of the tricks found in skateboarding have been able to cross over into snowboarding.




Although snowboarding and skateboarding are incredibly similar, there is one major difference between the two sports. The way that the participant's feet interact with each type of board in these two activities is completely different. On a skateboard the user's feet are not fixed to the board in an immovable manner. As a result of this, there is almost an unlimited amount of tricks available for a skateboarder to perform since the board is free to flip, spin, and or rotate in any direction relative to the rider. A skateboarder also has the option of removing either one or both of his feet from the board while riding to even further increase the variety of tricks he can execute. Because of the free connection of the rider's feet to the board, the amount of tricks or maneuvers that a skateboarder can perform is not limited by his equipment but only by his individual ability and imagination to invent new combinations.




In direct contrast to how a skateboard is ridden, a snowboarder has traditionally ridden with his feet fixed to the board in an immovable manner. The majority of snowboards are equipped with what are known in the art as conventional strap bindings. Although this type of binding can take on a multitude of forms with many different constructions they all share the same limiting characteristic. Strap bindings are designed to be solidly mounted to the snowboard deck and are not intended to separate from the board or permit the user's footwear members to release and then reattach while riding.




In addition to the conventional strap snowboard bindings, in recent years a variety of different step-in binding systems have been developed. These types of bindings are very similiar to the strap binding designs, but instead of straps some kind of mechanical operator is employed to secure the user's footwear into the bindings. Although in some areas of performance many of the step-in binding systems offer advantages over the strap binding designs, they still share the same limiting characteristic of their counterparts. Step-in snowboard bindings are also designed to affix the rider's footwear members to the board in a manner that is not intended to release and then reattach while one is riding.




In addition to the various strap and step-in binding systems that are widely in use, several forms of hybrid binding systems exist within the art. These systems aim to solve a variety of the different problems or drawbacks that are associated with all snowboard bindings in general. The hybrid bindings are most often concerned with issues like making the bindings easier and more convenient for the rider to use and actually do not function that much differently from the strap and step-in binding systems. There is also a category of snowboard bindings that have been designed to release from the board in some manner or another, but most of these systems are intended to operate like ski bindings with safety as their main consideration. There is yet to be a snowboard binding system designed to completely separate and then reattach to the board while one is riding in order to increase the number and type of tricks that can be performed.




With bindings that do not separate from the snowboard, it is possible to execute a limited amount of maneuvers where one removes his foot from the board. In order for these tricks to be performed, a rider has to either unstrap or disengage one of his bindings. The only option available for the rider is to unfasten his rear foot because at least one foot must stay attached to the snowboard in order for the rider to be able to steer the board and this is most easily accomplished with the front foot still attached.




With his front foot engaged with the front binding and his rear foot disengaged from the rear binding the rider can then proceed towards a jump or obstacle. He can hit the jump and perform a one-footed trick. The rider then has to land with his rear foot out of the rear binding and only resting on the snowboard deck. After landing the trick, the rider has to stop and replace his rear foot back into the rear binding before he can continue to ride like normal.




There are several drawbacks to this method of performing one-footed tricks. First of all, it is rather difficult to steer the snowboard with only one foot engaged in a binding. It is also somewhat dangerous to ride a snowboard when one foot is immovably fixed to the board and one foot is free. Also, the option of removing both feet while in the air to perform even more difficult tricks is not a possibility because of the fact that at least one foot has to remain attached to the snowboard in order for the rider to be able to control the snowboard.




With the bindings that are currently available for use with snowboards, the amount and types of tricks available for snowboarders to perform has been greatly limited. For riders looking to be able to execute more tricks with their snowboards there exists a need for a binding system that is designed to permit either one or both of the rider's feet to become completely separated and then reattach to the board while riding.




BRIEF SUMMARY OF THE INVENTION




The present invention is a device that can be employed to connect separate objects together in a manner that allows the individual objects to be coupled together, separate, and then reattach with each other. One area of application for the current invention is that it can be readily adapted to mount footwear members to a wide variety of recreational or sporting apparatuses, such as, for example skates, skateboards, snowboards, skis, etc. Even though the features of the current invention are described and illustrated herein in the specific context of snowboard bindings, it is not limited to snowboards because its features can be applied to a variety of recreational or sporting devices as well as to any two objects in general.




The footwear mounting system described herein has a refined, targeted design with several key advantages over the prior art. As directed to the sport of snowboarding, the present invention resolves the aforementioned problem with previous binding devices by making it possible for snowboarders to remove and then reattach either one or both of their footwear members from the board while riding. The invention accomplishes this by securing the footwear members used for snowboarding to the snowboard in every direction necessary to control the board except for one, so as to leave a method of release and subsequent reengagement. Allowing a snowboarder to completely separate either one or both of his feet from the board while riding is an improvement upon earlier devices from the aspect that it greatly increases the amount and type of tricks that the rider is able to perform.




Another solution of the present invention is to provide a binding system that releases in a natural manner while at the same time being somewhat easy to relocate into the locked riding position. The current invention operates with a method of release where the rider simply has to tilt either one or both of his feet forward or backwards in relation to the snowboard in order to separate one or both of his footwear members from the board. To reattach his footwear member or members into the locked riding position a rider just has to slide them back into place on the snowboard.




Yet another solution of the present invention is to supply a releasable and reattachable binding system that is safe for a rider to use by incorporating features which permit the user to select and or control when and if either one or both of his footwear members are able to separate from the snowboard. If a rider chooses to remove only one of his footwear members to perform a trick then these same features also provide a type of secondary safety release for the other member that is still attached to the snowboard.




A further solution of the invention is to have a releasable and reattachable binding system that will not clog with snow too easily. All of the parts are specifically shaped and designed to expel snow from their surfaces. The lateral engagement in combination with the relatively open method of mounting the binding to the snowboard all function to further eliminate or work around potential snow buildup within the system.




Additional features of the invention may include one or more of the following features.




The binding parts are specially shaped to help guide them into place with each other and thus facilitate a fluid engagement of the device.




Some of the binding pieces may have a plurality of holes or cutouts that function to remove snow from their surfaces.




A bottom surface of the footwear member is in direct contact with the top surface of the snowboard so that the forces necessary for controlling the board can be applied from the footwear.




The overlapping and interlocking connection between the two primary binding parts allows for multiple locations of attachment, including some where the separate members are not completely engaged, but still allow the rider to control or steer the snowboard.




Disclosed is a footwear mounting device that consists of two primary parts that are configured to release and reattach to each other.




A first angled bar is mounted to the snowboard deck and a second angled bar is incorporated with the footwear member.




A coupling unit is mounted upon the first angled bar and a corresponding coupling block is secured to the second angled bar. The coupling unit and the coupling block are designed to automatically engage with each other when the first and second angled bars are brought together in order to unite the two individual pieces.




The coupling unit includes a spring loaded latch that moves up and down in relation to the top surface of the snowboard in order to engage and disengage with the coupling block.




An additional unit to be known as the release enabler is mounted to the first angled bar in a position to interact with the coupling unit. With the release enabler a user is able to regulate the operation of the coupling unit. When the release enabler is in the open position the spring loaded latch can move to disengage with the coupling block and thus the angled bars can separate from each other. When the release enabler is in the closed position the spring loaded latch cannot move to disengage from the coupling block so the angled bars cannot separate from each other (unless they are exposed to a great deal of force whereupon the angled bars will separate as a matter of safety).




Advantages of the present invention include, but are not limited to the ability for snowboarders to release and then reattach either one or both of their footwear members from the board while riding. This is accomplished in a manner that is not only natural for the rider to execute, but also relatively easy for the rider to achieve because of the interlocking shapes of the individual binding parts, while at the same time being safe to use and considerably immune to snow buildup within the system.

DETAILED DESCRIPTION OF THE INVENTION





FIG. 1

illustrates the general layout of a snowboard


10


and footwear members


15


that have been equipped with the current invention. In most cases a snowboard


10


and footwear members


15


will be outfitted with two sets of releasable and reattachable connecting devices so that one pair corresponds to each of the user's feet. Since both sets of connecting devices are identical and interchangeable, only one set will be described in detail in order to simplify the description (except in cases where a discussion of both sets at once is necessary for the understanding of the invention).




Each releasable and reattachable connecting device is comprised of two main parts, the footwear angle


17


and the board angle


19


. In a preferred embodiment of the invention the overall shape of the board angle


19


is defined by a top face


80


, a slanted area


85


, and a bottom side


90


. The top face


80


of the board angle


19


features pieces to be referred to as the edge clips


21


. The edge clips


21


play an important role in the engagement between the board and footwear angle


19


,


17


. As viewed in the drawings, the edge clips


21


are separate members of the board angle


19


that are attached to the top face


80


of the board angle


19


by a set of t-nuts and flat headed screws


53


. But this is not the only manner in which this particular component of the invention can be constructed. The edge clips


21


could be affixed with a high strength adhesive or they could be formed as an integral part of the body of the board angle


19


.




The bottom side


90


of the board angle


19


features a device to be referred to as the coupling unit


30


. The coupling unit


30


is responsible for securing the board angle


19


and the footwear angle


17


together. It is comprised of a u-shaped latch


25


that rotates about a pivot rod


37


while being acted upon by a torsion spring


26


. The spring


26


is biased by a tension rod


38


and contact with the bottom side


90


of the board angle


19


. This entire assembly is anchored into place by being inserted through the latch mounts


27


. The latch mounts


27


are vertically extending fins that can be formed as part of the bottom side


90


of the board angle


19


. Although this is the best mode for carrying out the coupling unit


30


, other methods of construction could be called upon as well.




Another key component of the invention that is located in a position beside the coupling unit


30


on the bottom side


90


of the board angle


19


is the release enabler


20


. The release enabler


20


is a somewhat complicated device that governs the movement of the coupling unit


30


. One embodiment available for the release enabler


20


is most clearly viewed in FIG.


12


. Here each release enabler


20


is shown to have a body


45


that houses a movable shaft


28


where the movable shaft


28


can rest in two alternate positions in relation to the body


45


. The movable shaft


28


projects in length past the body


45


according to which alternate position that the movable shaft


28


rests in. The movable shaft


28


can be positioned over the coupling unit


30


(or u-shaped latch


25


) in order to impede its movement or it can be positioned to allow the coupling unit


30


(or u-shaped latch


25


) to move freely, To facilitate engagement and disengagement with the coupling unit


30


, the movable shaft


28


features a tapered tip


82


, Another feature of the movable shaft


28


is its oversized handle


75


that a user can easily grasp while wearing gloves in order to change its position, As with the other elements of the current invention there are obviously many additional ways of constructing the release enabler


20


and or any of its individual parts that could work as well as those just stated.




Located underneath the board angle


19


and performing several important functions are pieces to be referred to as the riser pads


33


, The riser pads


33


elevate the board angle


19


above the top surface of the snowboard


10


so that the footwear angle


17


will be able to slide underneath, The riser pads


33


also provide support for the board angle


19


. The ribbed segments


41


of the riser pads


33


keep the board angle


19


from being bent or smashed down from above. The riser pads


33


should be somewhat triangular in shape and contain a hole or plurality of holes to be involved with the mounting of the board angle


19


to the snowboard


10


.




Each board angle


19


should be mounted somewhere on the riding surface


14


of the snowboard


10


according to each rider's individual preference, There are a variety of different positions available for a rider to choose from. In

FIG. 1

a “left foot forward” (or regular footed) formation of the footwear members


15


is depicted, This layout can also be reversed to a “right foot forward” (or goofy footed) arrangement (not pictured). In addition, the relative angles that the board angles


19


are mounted to the snowboard


10


can be adjusted.




The best mode for mounting each board angle


19


(and riser pads


33


) to the snowboard


10


is with screws


52


, This technique is well known throughout the art as most snowboards that are produced include a plurality of threaded inserts that can receive the screws used for mounting the bindings. The board angle


19


and riser pads


33


could also be attached to the snowboard


10


with an appropriate adhesive or both of these parts could be formed along with the top sheet of the snowboard


10


.




Corresponding to the shape of the board angle


19


, the overall shape of the footwear angle


17


is defined by a top face


60


and a bottom side


70


. The bottom side


70


of the footwear angle


17


features a piece to be known as the coupling block


23


. The coupling block


23


is somewhat triangular in shape and is mounted in a position to be able to engage with the coupling unit


30


. The coupling block


23


can be held in place by screws


50


or it could be set in place by a suitable adhesive or formed as part of the body of the footwear angle


17


.




As seen in several of the drawings, the body of the footwear angle


17


can be mounted to bar-like structures


34


with screws


51


. These bar-like structures


34


can then be used as a means for attaching the footwear angle


17


to an appropriate type of snowboarding footwear member. The bar-like structures


34


can include pads


35


that serve several functions. One purpose of the pads


35


is to raise the footwear angle


17


to the proper height above the top surface of the snowboard


10


so that it fits tightly below the board angle


19


(as best seen in FIG.


6


). Another job of the pads


35


is to supply some amount of shock absorption for the binding system. The pads


35


should be formed out of a hard or soft rubber (or a similar kind of material) and can be glued into place on the bar-like structures


34


with a suitable adhesive or secured by a variety of different methods. In addition to the above configuration, other embodiments of the footwear angle


17


are possible. For example, it could just be formed as part of the strap binding


98


(as seen in

FIG. 3

) or a special footwear member


99


could be constructed having the body of the footwear angle


17


protruding from one side of its sole (as seen in FIG.


4


).




The bodies of both the footwear angle


17


and the board angle


19


must be able to withstand the stresses that they will encounter as they are being employed as bindings for a snowboard


10


. In this role they will also be required to operate under a wide variety of temperature and weather conditions. Both of these pieces


17


and


19


should be constructed from a material or combination of materials that are lightweight, strong, and resist adhesion to snow and ice particles. Examples of suitable materials would include high strength aluminum, carbon fiber, a synthetic thermoplastic resin (such as polyethylene, nylon, Delrin, Teflon, etc.), or any other suitable material that possesses the desired qualities. The present invention may be cast or molded, as with an injection process, from such materials in no more than a few pieces and then assembled into the final form.




Now that the main parts of the releasable and reattachable connecting device have been identified it is time to describe how they function when utilized as snowboard bindings that can release and reattach to the board.




In order to steer or turn (also known as carving) on a snowboard


10


, the positioning of a rider's footwear members


15


on the board must be fixed (they cannot move around completely free like on a skateboard). To carve turns on a snowboard


10


a rider either raises his toes and leans back on his heels to go in one direction (also known as a frontside turn) or he raises his heels and pushes down on his toes to go in the opposite direction (also known as a backside turn). Thus, a snowboard binding system must at a minimum completely anchor the rider's heels and toes to the board.




On the present invention this is accomplished through the overlapping connection of the board angles


19


with the footwear angles


17


. This is best viewed in

FIG. 6

where it can be seen how the bottom side


90


of the board angle


19


covers the bottom side


70


of the footwear angle


17


when the two parts are engaged with each other. This configuration secures the rider's toes and heels to the snowboard


10


in a manner that enables him to bring the board up on either edge to steer the board.




In addition to the above requirement for steering a snowboard


10


, to keep a board under control, a rider's footwear members


15


cannot move side to side in relation to the left edge


11


or right edge


16


of the snowboard


10


. The present invention meets this need with the edge clips


21


that are located on the top faces


80


of each of the board angles


19


. They work in unison with the aforementioned overlapping connection between the board angles


19


and the footwear angles


17


to keep the rider's footwear members


15


fixed in their position on the snowboard


10


.




And finally, a snowboard binding system cannot permit a rider's footwear members


15


to move forward towards the front (or nose)


12


of the snowboard


10


or backward towards the rear end (or tail)


13


. The abutment of the top faces


60


of the footwear angles


17


with the corresponding top faces


80


of the board angles


19


and the respective connections between the coupling units


30


and the coupling blocks


23


prevent the user's footwear members


15


from moving forward or backward in relation to the snowboard


10


. When the footwear angles


17


and board angles


19


are united by the complementary shapes of their individual parts an adequately fixed connection is achieved. This connection allows a rider to turn or carve the snowboard


10


in the same manner as one that is equipped with a conventional binding system.




With the conditions necessary for steering the snowboard


10


met by the current invention a method for releasing the rider's footwear members


15


from the board is now required. The main concept behind this invention is to introduce a device that secures a rider's footwear members


15


in every manner necessary to control the board except for one. The direction that is omitted then becomes the method by which the invention can allow the footwear members


15


to completely release from the snowboard


10


.




The arrows in

FIG. 2

illustrate the directions that the current invention secures the rider's footwear members


15


in relation to the snowboard


10


. It can be seen how the releasable and reattachable connecting device does not allow the rider's footwear members


15


to move forward towards the front (or nose)


12


of the snowboard


10


, backward towards the rear end (or tail)


13


, sideways towards the left edge


11


, sideways towards the right edge


16


, or up in a direction perpendicular to the top surface of the snowboard


10


. These restrictions leave only one direction for the device to move in order to release.




The releasable and reattachable connecting device will only separate when it is tilted, as displayed by the arrows in FIG.


7


. When a footwear angle


17


is tilted it causes the coupling unit


30


(or u-shaped latch


25


) to release from the coupling block


23


. This, in turn, allows the footwear angle


17


to disengage from the board angle


19


. When the footwear angles


17


are attached to the outsides of the footwear members


15


as seen in

FIG. 1

, the front footwear angle


17


will have to tilt in a direction towards the front (or nose)


12


of the snowboard


10


and the rear footwear angle


17


will have to tilt in a direction towards the rear end (or tail)


13


of the snowboard


10


. This is how a rider is able to remove one or both of his footwear members


15


from the snowboard


10


while it is in motion (some other conditions, discussed later under the safety concerns must be met before release can actually occur).




Because the releasable and reattachable connecting device is comprised of two main members that can separate from each other, the next major design concern is to make reuniting the pieces back together (relocating the footwear members


15


back onto the snowboard


10


, sometimes while jumping through the air) as fluid and automatic as possible.




Several aspects of this invention function simultaneously to guide the footwear angles


17


back into place with the board angles


19


. First of all, as illustrated in several of the drawings, the lateral engagement of this binding system facilitates realignment because a rider can place his footwear member or members


15


onto the riding surface


14


of the snowboard


10


and then slide them into the locked riding position. Next, the slanted areas


85


of the board angles


19


play an important role in reuniting the two separate pieces of the device. These areas


85


provide a crucial amount of clearance for the footwear angles


17


to return to their position underneath the board angles


19


. Because of the slanted areas


85


a rider can also elect to bring the footwear angles


17


back into position on the snowboard


10


with the same angled movement as when they were released.




In addition to these features, the shape of the edge clips


21


helps to direct the footwear angle


17


back into the correct locking position with the board angle


19


(as best illustrated by the arrows in FIG.


10


). Also, the slanted comers


72


of the footwear angle


17


help to guide it into position with the board angle


19


. At the same time the angled cut-outs


65


of the footwear angle


17


fit around the ribbed segments


41


of the riser pads


33


so that the footwear angle


17


can slide underneath the board angle


19


. Another important aspect of the current invention is that a rider's foot placement upon returning to the board does not have to be exact. As seen in

FIG. 11

, a rider can get his footwear member or members


15


close to where they need to go and still have control of the snowboard


10


until the device returns to a completely locked, ridable position. All of these details combine to provide a fluid and somewhat automatic method of re-engagement for the separate pieces of the releasable and reattachable connecting device either while the rider is on the ground or flying through the air.




Safety is a major concern with any snowboard binding and it is particularly crucial in the case of the present invention since it permits either one or both of the user's footwear members


15


to completely separate from and then return to the snowboard


10


while riding. Conventional strap snowboard bindings as well as their step-in binding counterparts are not designed to release from the board while riding and few injuries result from falls and crash landings. But it is an altogether different situation when it comes to a binding that can release from the board while riding. Very dangerous conditions can arise when one footwear member


15


is released and one footwear member


15


is still fixed to the snowboard


10


. If a rider fell in that situation, he could become quite injured because the board could twist with a great deal of force and cause serious injury to his feet, ankles, and or legs.




The tilted method of release that allows the footwear angle


17


to separate from the board angle


19


has one major drawback that has to be overcome while at the same time keeping the system safe to use. This device if left as discussed so far will release rather easily while one is riding it. When tilting one footwear member


15


, it is very difficult not to tilt the other one and cause both to release at the same time. So if a rider only wants to disengage one footwear member


15


to perform tricks like those illustrated in

FIGS. 12 and 13

the opposite binding must be kept from releasing unintentionally while still being allowed to release in the event of a crash landing.




The coupling unit


30


is the part of the invention that is most directly responsible for the engagement or separation of the footwear angle


17


from the board angle


19


. Thus, the movement of the coupling unit


30


must be closely regulated and this is the job of the release enabler


20


. With the release enabler


20


, the user has the option of selecting from an “open” or “closed” position for either one or both of his footwear members


15


. In

FIG. 9

, it can be seen how the “open” position of the release enabler


20


(where the movable shaft


28


does not cross the u-shaped latch


25


) permits the coupling unit


30


to move freely. This allows the footwear angle


17


to willingly engage or disengage from the board angle


19


. In

FIG. 8

, it can be seen how the “closed” position of the release enabler


20


(where the movable shaft


28


does cross over the u-shaped latch


25


) restricts movement of the coupling unit


30


. This results in a more powerful attachment of the footwear angle


17


to the board angle


19


.




Although the release enabler


20


is capable of more strongly securing the footwear angle


17


to the board angle


19


, it will still allow the footwear angle


17


to release upon being exposed to a predetermined amount of force. This feature is best described as being a form of safety release for the binding system and it relies upon a property that all snowboards share.




Snowboards are designed to flex in several directions while one is riding them and this characteristic can be taken advantage of to provide a method of safety release for the current device. Safety release means that even when a footwear angle


17


is secured underneath a board angle


19


by the engagement of the coupling unit


30


with the coupling block


23


in combination with the release enabler


20


being in the closed position, the footwear angle


17


can still be made to release when exposed to predetermined amounts of force (or board flex). In other words, if a rider crashes after only setting one footwear member


15


to release from the board, the other footwear member


15


that was still fixed to the snowboard


10


will also release upon being exposed to the forces (or board flex) that it will undergo during the crash landing.




Several parts of the connecting device can be attuned to work in conjunction with the natural flex patterns of the snowboard


10


in order to adjust and regulate the operation of the safety release. To begin with, the release enabler


20


should not be immovably fixed to the board angle


19


. It should be connected in a manner that allows a user to adjust how tightly it is mounted. One method of attachment that meets this requirement is illustrated in FIG.


12


. Here the release enabler


20


is secured to the bottom side


90


of the board angle


19


on a mounting pad


31


and held in place with a group of screws


92


and nuts


95


. A plurality of lock washers


93


should also be included so that the strength of the connection can be adjusted according to each rider's individual requirements. Besides this particular construction there are obviously many other ways to anchor the release enabler


20


while at the same time allowing it to slightly move upon being exposed to a predetermined amount of force (such as the use of a plurality of compression springs instead of the lock washers


93


).




In addition to having a “floating” release enabler


20


, the relative tightness of the mounting screws


52


can be adjusted to control how far the board angle


19


has to flex in conjunction with the snowboard


10


before resulting in safety release. Also, the height of the coupling block


23


can be varied as yet another method of determining how much board or binding flex is required before safety release can occur. A taller coupling block


23


means that a greater amount of force will be needed to activate safety release while a shorter coupling block


23


results in less force being required to achieve safety release. All of these features can be adjusted individually or as a group until a rider discovers a safety release setting that works best for his particular ability and riding style.




The last objective to be met by the present invention when it is adapted for use with snowboards is that it should be designed to not clog with snow too easily and or still be able to operate with some snow buildup within the system. No snowboard binding is always going to completely keep snow from lodging within its parts, but steps can be taken to reduce the amount that does. Areas that must not become clogged with snow include all of the contact points between the board angles


19


and the footwear angles


17


. If snow and ice particles accumulate on these pieces they will not be able to freely engage and disengage with each other. The plurality of holes


24


that are located on the top faces


60


of the footwear angles


17


combat snow buildup in this area. For the bottom sides


70


,


90


of the footwear and board angles


17


,


19


the space provided by the slanted areas


85


of the board angles


19


allows for a small amount of snow buildup within the system while still permitting the binding to operate (as best seen in FIG.


6


).




Another realm that should be kept clear of snow is the area located underneath the board angles


19


in the space between them and the top surface of the snowboard


10


. The open design of how the board angles


19


are mounted to the snowboard


10


in combination with the lateral engagement of the footwear angles


17


with the board angles


19


helps to push snow out from under the bindings. Also, the area where the coupling units


30


enclose the coupling blocks


23


must be kept clear of snow in order for the device to operate properly. To meet this requirement the segments of the bottom sides


70


of the footwear angles


17


that the u-shaped latches


25


rest upon when engaged with the coupling blocks


23


have been cut out


55


. To even further reduce the buildup of snow and ice particles from within the releasable and reattachable connecting device, other embodiments could be constructed that have larger openings in certain areas and or contain additional holes or cutouts in places where snow tends to accumulate.




By adapting the features of the releasable and reattachable connecting device for use in the sport of snowboarding a larger number of tricks from skateboarding will now be able to cross over into the sport of snowboarding.





FIG. 13

demonstrates how a rider can remove and replace his front footwear member


15


from the snowboard


10


in order to perform a trick (which is known as a judo air).

FIG. 14

shows how a rider can remove and replace his rear footwear member


15


from the snowboard


10


in order to perform another kind of trick. To execute these types of one-footed maneuvers a rider has to follow certain steps. First of all, he has to decide which footwear member


15


that he wants to remove and then return to the snowboard


10


. If a rider wants to release his front footwear member


15


to do a trick, then he has to place the front release enabler


20


in the open position. If a rider wants to release his rear footwear member


15


to do a trick, then he has to place the rear release enabler


20


in the open position. He can then ride over the jump or obstacle, tilt and remove whichever footwear member


15


he has chosen to release, style out the trick, replace his free footwear member


15


back into the binding, land and ride away (reaching down to slide the release enabler


20


back into the closed position if he does not want to release his foot anymore).




Even more complicated tricks can be performed on snowboards according to the present invention.

FIG. 15

illustrates how a rider can choose to remove and replace both of his footwear members


15


from the snowboard


10


and or rotate the board in relation to himself in order to perform very difficult maneuvers. To execute these types of stunts the rider has to place both release enablers


20


(front and rear) in the open position. He can then travel over some type of obstacle or jump, tilt both of his footwear members


15


in the respective directions required to release them, (rotate the board in relation to himself), return his footwear members


15


into position on the board, land and ride away (once again reaching down to place the release enablers


20


in the closed position if he does not want to remove his feet again).




Note: When executing any of the above maneuvers it is important for the rider to grab the snowboard


10


earlier than normal and also hold onto it longer than normal in order to have a better chance of completing the trick.




These are only some examples of the types of tricks that can now be performed on snowboards outfitted with the present invention. With this device there is virtually no limit to the variety and amount of tricks that can be executed on snowboards. The only restriction on the progression of the sport of snowboarding will be the imagination and skill of the individual riders involved.




The preceding description should be more than adequate to allow someone skilled in the art of snowboards and snowboard bindings to adapt and use the features of the releasable and reattachable connecting device for the sport of snowboarding. After disclosing the principles of the invention with drawings and in writing with reference to multiple preferred embodiments, it is obvious that additional modifications and adaptations will arise to those skilled in the art. Nevertheless, it is to be explicitly understood that such modifications and adaptations are all within the range of the present invention. Thus the scope of this invention should be decided by the accompanying claims and their legal equivalents.
