1. Field of the Invention
The present invention relates generally to sports boards, such as skateboard, surfboards, snowboards, windsurfing boards, kitesurfing boards, wakeboards, and the like, and more particularly to binding methods and methods of providing foot traction on such boards.
2. Discussion of Related Art Including Information Disclosed Under 37 CFR 1.97 and 37 CFR 1.98
The 2006 Winter Olympics brought a high level of world attention to the growing popularity of board sports. In the case of the Olympic Games, the prominent sport was snow boarding, but with only a little attention to the commentary and interviews with the athletes, it became obvious that the favored off season sport of snow boarders was skateboarding. These sports, along with a rapidly growing number of alternatives to mainstream sports, are coming to be known as extreme sports. They include such things as rock climbing, windsurfing, kite surfing, snowboarding, snow skating, inline skating, roller hockey, women's hockey, skateboarding, motocross racing, freestyle BMX bike riding, technical canyoneering, whitewater kayaking, base jumping, sky surfing, and so on. Indeed, a full embrace of such “thrill” sports appears to be tracking the more general cultural practice of aesthetic self-fashioning, and as that culture matures, a culture in which death is increasingly felt to be remote and unlikely (due to sophisticated medical practices and increased life spans) yet more real and dreadful (due to skepticism and decreased religious belief), brushes with death are all the more compelling. And so it is that youth will even more dramatically push the boundaries of the possible, challenge life (and death) and perform remarkable and beautiful feats in the process.
Interestingly, participants in extreme sports also demand good equipment. Whole industries thrive on providing stronger, lighter, faster, more durable, and better performing gear. This is certainly the case for binding methods for snow boards, windsurfing boards, skis, and the like. Recent contributions to the field of binding methods are far too numerous to list and describe. But a few developments in the field of magnetic binding apparatus are of note.
For instance, U.S. Pat. No. 3,960,383, to O'Neil, teaches a ski-binding system including front and rear coupling units attached a ski and cooperating boot attachments of magnetically sensitive material. Each unit includes magnetics such that when a ski boot provided with the attachments is positioned between the units, the boot is secured by the magnetic attraction between the boot attachments and the magnetic units. As a first instance of magnetic binding methods, the cleverness of the '383 patent is undeniable, but its practical utility is almost entirely restricted to use on skis, as the binding units are bulky, fixed, and work only with relative rigid boots.
U.S. Pat. No. 5,954,357, to Golling, discloses a snow boot and binding system for snow skiing or snow boarding in which only magnetic forces are used to affix the snow boot to the ski or snow-board. The system comprises three components, namely, a support base in ski or snow board, a foot enclosure assembly, and release means connected to the foot enclosure assembly for releasably interconnecting the foot enclosure assembly with the support base. The support base has spaced-apart recesses within which are mounted magnets, either singly or in an array. the foot enclosure comprises a snow boot having metal plates affixed to the lower surface and the back of the snow boot. The release means essentially comprises a lever system for prying the boot off the support base through moving a cam handle. While this system allows for selective placement of the user's feet on the sports board, it entails the use of rigid boots and so is truly suitable only for snow boards, but not for skateboards, surfboards, wakeboards, and other sports boards used with free feet.
U.S. Pat. No. 6,299,192 to Bryce shows a binding apparatus for use with sports boards such as skate boards, which includes two knobs integral with the top of the board and which insert into matching recesses in each of the user's shoes. The knob may include a compression ring or the knob and shoes may include cooperating magnets that hold the two together up to a predetermined breakaway force. The limitation of this method is that the user's feet are fixed at the position of the knobs.
U.S. Pat. No. 6,863,583 to Takahashi, discloses a surfboard having a magnetic region made of permanent magnets, which is, in turn, covered by a foot pad, and to which a surfer is secured through shoes having ferromagnetic material included in the soles. The inventive principles in the '583 patent providing the launch point for the novel improvements of the present invention, in that the '583 patent does not teach or disclose any means for interchanging, adjusting, and selectively removing the magnetic region in the sports board.
The foregoing patents reflect the current state of the art of which the present inventor is aware. Reference to, and discussion of, these patents is intended to aid in discharging Applicant's acknowledged duty of candor in disclosing information that may be relevant to the examination of claims to the present invention. However, it is respectfully submitted that none of the above-indicated patents disclose, teach, suggest, show, or otherwise render obvious, either singly or when considered in combination, the invention described and claimed herein.
The present invention is a magnetic sports board binding and foot traction apparatus. In its most essential aspect, the inventive apparatus comprises one or more magnet holding receptacles disposed in the upper surface of a sports board, each receptacle having a ferromagnetic bar disposed in or under at least a portion of the bottom of the receptacle. Permanent magnets are selectively placed into the one or more receptacles and each bind to the ferromagnetic bar, holding them firmly in place even during the most violent of sports activities. The insertion of the magnet(s) into the receptacles thus forms a magnetic region on the surface of the sports board. The sports board user is then provided with footwear having a ferromagnetic plate affixed to, or incorporated into, at least a portion of the sole of the footwear. Accordingly, when the user mounts the sports board and brings his or her foot into proximity with the magnetic region of the sports board, footing and traction are enhanced.
In a preferred embodiment, the magnet holding receptacles are formed in a box, preferably polycarbonate, which may be formed into the sports board at the time of manufacture or placed into a recess cut into the board for a retrofit installation. The box provides magnet holding receptacles in an ordered array according to the kind of footwork anticipated during board use.
In the preferred embodiment, the permanent magnets are cylindrical disks having finger or tool gripping means on their upper surfaces so that they can be easily lowered into and pulled out of the magnet holding receptacles. In this fashion, the magnetic region of the sports board can be precisely tailored to the wants and needs of the user by employing a very specific magnet or combination of magnets that create the desired holding power.
It is therefore an object of the present invention to provide a new and improved sports board binding and foot traction apparatus.
It is another object of the present invention to provide a new and improved sports board binding and foot traction apparatus that employs magnets alone as the binding force.
A further object or feature of the present invention is a new and improved sports board binding and foot traction apparatus that enables a rapid change in the binding force provided by the magnets so that different safety and/or performance requirements can be addressed.
An even further object of the present invention is to provide a novel sports board binding and foot traction apparatus that can be selectively used or eliminated entirely when so desired by the user.
Other novel features which are characteristic of the invention, as to organization and method of operation, together with further objects and advantages thereof will be better understood from the following description considered in connection with the accompanying drawings, in which preferred embodiments of the invention are illustrated by way of example. It is to be expressly understood, however, that the drawings are for illustration and description only and are not intended as a definition of the limits of the invention. The various features of novelty that characterize the invention are pointed out with particularity in the claims annexed to and forming part of this disclosure. The invention does not reside in any one of these features taken alone, but rather in the particular combination of all of its structures for the functions specified.
There has thus been broadly outlined the more important features of the invention in order that the detailed description thereof that follows may be better understood, and in order that the present contribution to the art may be better appreciated. There are, of course, additional features of the invention that will be described hereinafter and which will form additional subject matter of the claims appended hereto. Those skilled in the art will appreciate that the conception upon which this disclosure is based readily may be utilized as a basis for the designing of other structures, methods and systems for carrying out the several purposes of the present invention. It is important, therefore, that the claims be regarded as including such equivalent constructions insofar as they do not depart from the spirit and scope of the present invention.
The invention will be better understood and objects other than those set forth above will become apparent when consideration is given to the following detailed description thereof. Such description makes reference to the annexed drawings wherein:
Referring to
The next element in the inventive apparatus comprises one or more permanent magnets, 150, 160, 170, which are disposed in the magnet holding receptacles. The magnets are preferably either ceramic (strontium ferrite) magnets, rare earth magnets, or aluminum/nickel/cobalt (Alnico) magnets. Even more preferably, the magnets may be samarium cobalt magnets, nickel plated and unplated neodymium magnets, and/or neodymium-iron-boron magnets. The choice will be largely driven by the desired holding power, the mass of the magnet suitable for use, and costs. No matter what kind of magnet is selected, it is shaped and sized for a close fit insertion into one of the receptacles. A preferred shape, then, of both receptacle and magnet is that of a cylindrical plug, as illustrated. The desired holding power, in turn, will be driven by the weight of the user, the forces encountered during performance, and the degree to which the user wishes to be bound to the board or to be free to move and reposition his or her feet. Indeed, because a user may wish to fine tune the binding power provided in the magnetic region of the board, the magnets are preferably fabricated with grips or handles 180, 190, 200 integrated into or attached to their upper surfaces. These will allow the user to pull the magnets out of the receptacles using either fingers or a simple tool adapted for such use. In the alternative, the upper surface of the magnets can be kept entirely planar so that holding power is not in any respect compromised, and a tool, such as a hand held magnet with an attached handle, or ferromagnetic block having a handle. In either case, the magnet removing tool need only have an attractive force stronger than that of the ferromagnetic material disposed in the magnet holding receptacle, such that upon placing it over a magnet disposed in a receptacle, the magnet will bind to the tool and can then be lifted out of the receptacle. Replacement of magnets does not require the use of any tool. Rather, a new magnet may be dropped into a receptacle using fingers only. In this manner, the presence, the shape, and the strength of the magnetic field produced by the magnets can be nicely fit to the user and his or her demands.
As will be readily appreciated, the magnet holding receptacles may be incorporated into the sports board at the time of manufacture or may be installed as part of a magnet holding box 210 disposed in a cutout 220 formed in an already manufactured board 230.
The next element in the inventive apparatus is a ferromagnetic plate 240 affixed to or incorporated into footwear 250 to be worn by the board user. The footwear may be a wetsuit bootie, a sports sandal, tennis shoe, skate shoe, and the like. Accordingly, the plate may be sewn into the fabric of a wetsuit bootie, molded into the sole of a skate shoe or sports sandal, or otherwise affixed by adhesives, rivets, or other fastening devices. Because of the power of the permanent magnets, the ferromagnetic plate need not be so thick that it interferes with natural foot movement. Preferably it is positioned generally near the ball of the foot, though, again, it may be sized and positioned according to the particular wants and needs of the user.
In another aspect, the inventive apparatus can be conceived of as a sports board foot traction kit that includes a magnet holding receptacle box having an upper surface with a number of recesses in the upper surface; several permanent magnets (preferably of a variety of holding powers) for selective placement in the recesses; and means for rapid and easy removal and replacement of the magnets from the recesses. This portion of the kit can be installed as a retrofit in a sports board simply by providing a cutout of suitable size in the upper surface of the board. Footwear having ferromagnetic material in the shoe sole can then be provided to cooperate with the magnets to provide traction and binding power.
The above disclosure is sufficient to enable one of ordinary skill in the art to practice the invention, and provides the best mode of practicing the invention presently contemplated by the inventor. While there is provided herein a full and complete disclosure of the preferred embodiments of this invention, it is not desired to limit the invention to the exact construction, dimensional relationships, and operation shown and described. Various modifications, alternative constructions, changes and equivalents will readily occur to those skilled in the art and may be employed, as suitable, without departing from the true spirit and scope of the invention. Such changes might involve alternative materials, components, structural arrangements, sizes, shapes, forms, functions, operational features or the like.
Therefore, the above description and illustrations should not be construed as limiting the scope of the invention, which is defined by the appended claims.
