Description

BACKGROUND OF THE INVENTION

Wakeboard bindings are foot bindings which are adapted and designed to be employed on a wakeboards, wherein the wakeboard is a recreational sport board, so that the person riding on the wakeboard can be towed behind a boat or jet ski. Wakeboard bindings are generally mounted transversely on a wakeboard, similar to bindings mounted on a snowboard. One wakeboard binding is described in U.S. Pat. No. 5,624,291, issued Apr. 29, 1997.

It is therefore desirable to provide for a new and improved wakeboard bindings and wakeboard system containing the bindings, which wakeboard bindings and system provides certain advantages over the prior art in regard to performance, use, and structure.

SUMMARY OF THE INVENTION

The invention relates to wakeboard bindings and a wakeboard system employing the bindings.

The wakeboard binding of the invention is adapted to be secured to a wakeboard, which binding comprises a bottom support plates typically of aluminum, having a front end, a rear end, a left edge, a right edge, a top surface, and a bottom surface, and characterized by a left row of a plurality of apertures, and a right row of a plurality of apertures. The wakeboard binding includes a cushion foot pad, typically of a molded, flexible foam material of various colors and usually die cut to size. The wakeboard binding includes a heel receptacle having a back surface and a lower edge, with a plurality of apertures generally aligned with the apertures on the support plate, and the heel receptacle extending about the back of the heel of a user. The wakeboard binding also includes a toe receptacle having a top surface and a left and right end, each with a plurality of apertures, and generally aligned with the apertures of the support plate and extending across the top of the foot of a user. The toe and heel receptacle material is usually composed of a rubber sheet material, and more particularly an elastomeric metallocene rubber (EMR) which may be physically bonded to a foam sheet material and die cut to size to provide interior comfort. The EMR and the foam material may vary in density, thickness and color, such as, the foam material having about 22 pounds per cubit foot density and about 0.185 inch thickness and screened with selected graphics. The heel and toe receptacle form a boot-like enclosure on the top surface of the support plate over and about the selected foot pad to receive the foot of the user.

The wakeboard binding includes a binding overlay comprising a single piece of a sheet material having a top, a bottom, and a base section to extend about the surface of the heel receptacle and with an open bottom, heel cup section to extend over and across the heel of a user, and a top left and a top right outwardly elongated, spaced apart, extending arms from the base section, and a bottom left and a bottom right outwardly elongated, spaced apart, extending arms from the base section, and generally, the arms being of a uniform length and parallel to each other. Each arm at the end thereof has a plurality of apertures therein, generally, the apertures are aligned to be adjustably secured to a plurality of apertures in the bottom support plate. The top and bottom arms of the binding overlay are adapted to extend over and across the top surface of the toe receptacle in a crisscross arm relationship. The binding overlay usually comprises a rubber sheet material, and more particularly, a one piece, die cut, EMR sheet material with adjustable holes punched, as desired, for alignment with the apertures in the support plate. The EMR material permits varying selected properties to be employed, such as, varying the density, thickness, or color of the material.

The wakeboard binding also includes a means to clamp respectively, the ends of the extending arms of the binding overlay and the toe and heel receptacle, through the respective apertures, to and into the top surface of the bottom plate by the employment of adjustable, stainless steel machine screws. The support plate typically is formed of an anodized aircraft aluminum, for example, having a thickness of about 0.100 inches. The means to clamp comprises left and right toe bars with holes therein and a molded heel horseshoe-type clamp, through which stainless steel machine screws or bolts may be employed to secure the sides of the toe and heel receptacle and the arms of the binding overlay to the support plate. The wakeboard binding may include an adjustable opening means in the top back of the binding overlay to permit the easier entry of a user's foot into the boot enclosure, such as, the employment of a zipper or an extended pull-on-strap. In addition, the heel and toe receptacle may also include on the top surface thereon, a pair of spaced apart holes aligned on the heel and toe receptacle to aid a user in placing his foot into the boot-like receptacle.

The support plate is characterized by a heel aperture, usually directly positioned beneath the heel of a user, which aperture may, for example, be a rounded trapezoid or other shape aperture and which would include therein a heel cushioning material, such as; but not limited to, a resilient honeycomb air-cell, plastic heel cushion material, die cut to size and of about 1/4 inch thickness. The support plate may also be characterized by a substantially circular arc or arcuate, generally open section, centrally located and extending inwardly from the front end of the support plate.

The construction of the wakeboard binding of the invention provides for a plurality of improvements in the structure, performance, and use of the wakeboard binding.

The support plate enables the user to not only rotate each binding to various degrees, but also enables the user to move the plate forward and back over the width of the wakeboard. This allows for users with smaller and larger feet to be centered over the wakeboard.

The keyway system of heel and front apertures allows the manufacturer to use less aluminum material to produce the plate part, thus reducing the weight of the plate. The keyway system also allows the manufacturer to use the same plate for the various sizes. A specialized keyway insert can be put in to handle all types of footbed shapes.

The hardware used comprises a polymer molded, e.g., nylon toe bar and heel horseshoe clamps, optionally, with adjustable overlay bars. The hardware system allows the user to adjust the tension on the binding overlay, with overlay bars, through arm length adjustment, without disassembling the entire heel and toe pieces. In one embodiment, instead of running the overlay under the same hardware that the heel and toe are under, there are separate overlay bars that clamp the overlay between the two pieces of nylon hardware. This system enables the user to rotate the overlay around the radius of the heel horseshoe shape and back and forth along the toe bars. This gives each user the ability to easily modify their bindings to fit their comfort needs. All users usually modify their bindings currently, but it is very difficult because all the material is clamped under the same bars.

The support plate is characterized by a machined hole in the plate directly under the heel of the user. This space allows for a die cut piece of the honeycomb air-cell to be placed in direct contact with the bottom of the footbed pad. This provides the user with a cushion material directly under the heel. The cushion provides a softer landing on air tricks and also absorbs the kinetic energy. Less energy being pushed into the wakeboard will lengthen the board life and comfort the user.

EMR material has been developed to lessen the weight of the binding and enable the binding manufacturer to use various densities thicknesses, and colors. Currently, the industry has used neoprene rubber to produce bindings, so all bindings developed in the industry have the same black look and characteristics. The (EMR) material allows the wake binding quickly to adjust to the changing needs of the market as to color, color combinations, and comfort.

The binding overlay is a single piece of die cut sheet material. The shape of the overlay is a direct function of certain qualities needed to produce a high-end bindings. The heel area is cut out, providing a heel cup or a "pocket" to keep the user's heel locked down in place. The bottom two arms of the overlay are crisscrossed over the top of the toe pieces This provides a user with adjustable support over their toe, minimizing any toe lift. The top two arms of the overlay are also crisscrossed and pulled around to the backsides of the heel horseshoe hardware. The tension and placement of this part of the overlay is also adjustable. These arms are a key part to the overlay binding. Depending on the desired tension by the user, the top arms pull the user's foot and ankle back into the heel "pocket" of the binding. This will minimize the heel lift when performing surface and air tricks. The less heel lift within the binding, the more direct edge control of the wakeboard.

The tight tension created by this binding overlay made it difficult to put on and take off the binding. This lead to the optional, but suggested, addition of the rear entry binding system. The binding can now be put on and taken-off easily and still maintain the tight tension qualities needed in a performance wakeboard binding.

Optionally and preferably, an ankle strap is sewn in place along the top edge of the binding overlay providing the last element needed to prevent any heel lift. This strap, pulled tight around the user as ankle through a D-ring and back around the ankle, sticking onto itself with the VELCRO.RTM. (hook and loop fabric), will keep the user's entire foot down in the heel "pocket". The ankle strap allows the high-end rider to be physically restrained into the binding. The foot is able to be pulled out of the binding, but centrifugal force and gravity will not allow the binding to slip during surface or air maneuvers.

In a further embodiment of the invention, which embodiment may be employed generally in wakeboard bindings as a heel receptacle, and particularly with wakeboard bindings having an integral binding overlay as described, the heel receptacle may employ a strap secured thereto to aid in the insertion of a user's foot into the boot-like enclosure.

A sturdy strap, like woven nylon strap, has a top loop extending above the top of the heel receptacle material, e.g., 1 to 3 inches, so that the user may grasp the open loop for assistance in pulling on the wakeboard binding. This loop replaces the use of finger holes presently employed in the art which has been found to sometimes cause ripping of the heel receptacle material.

The strap extends generally centrally down the outside of the heel receptacle and is firmly secured, typically by stitching it to an upper and lower section of the heel receptacle to form an intermediate free loop between the stitched secured section. This arrangement transfers the load or user pulling force to the strap, rather than to the heel material and avoids tearing or ripping of the heel receptacle material in use.

The strap is turned over at the lower end to the lower secured section to form a lower strap loop. This lower loop is for anchoring purposes and is designed so that the heel clamp used generally the horseshoe-shaped heel clamp, passes through the lower loop to anchor the lower end of the strap securely to the heel clamp which is bolted to the support plate.

The extended, multiple loop, secured strap may be used alone to aid insertion of a user foot into the wakeboard binding or in combination with a back closure, such as a zipper, in the wakeboard binding overlay adjacent the back heel enclosure.

The invention shall be described for the purposes of illustration only in connection with certain illustrated embodiments; however, it is recognized that various modifications, additions, improvements, and changes to the illustrated embodiments may be made by those persons skilled in the art without departing from the spirit and scope of the invention as disclosed and claimed.
