Description:

BINDING/SKI BRAKE SYSTEM BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to a binding/ski brake system and more particularly pertains to positioning ski bindings laterally offset, closer to the inner edges of skis than to the outer edges, for maximizing control while configuring brakes to accommodate such binding positioning, all in a safe, convenient and economical manner. Description of the Prior Art The use of ski brake systems of known designs and configurations is known in the prior art. More specifically, ski brake systems of known designs and configurations previously devised and utilized for the purpose of configuring ski braking systems though known methods and apparatuses are known to consist basically of familiar, expected, and obvious structural configurations, notwithstanding the myriad of designs encompassed by the crowded prior art which has been developed for the fulfillment of countless objectives and requirements. By way of example, U.S. Patent Number 4,012,057 issued March 15, 1977 to Courvoisier relates to a Ski Brake and U.S. Patent Number 6,390,491 issued May 21, 2002 to Hunter relates to a Downhill Ski with Integrated Binding/Traction Device. While these devices fulfill their respective, particular objectives and requirements, the aforementioned patents do not describe a binding/ski brake system that allows for positioning ski bindings laterally offset, closer to the inner edges of skis than to the outer edges, for maximizing control while configuring brakes to

accommodate such binding positioning, all in a safe, convenient and economical manner. In this respect, the binding/ski brake system according to the present invention substantially departs from the conventional concepts and designs of the prior art, and in doing so provides an apparatus primarily developed for the purpose of positioning ski bindings laterally offset, closer to the inner edges of skis than to the outer edges, for maximizing control while configuring brakes to accommodate such binding positioning, all in a safe, convenient and economical manner. Therefore, it can be appreciated that there exists a continuing need for a new and improved binding/ski brake system which can be used for positioning ski bindings laterally offset, closer to the inner edges of skis than to the outer edges, for maximizing control while configuring brakes to accommodate such binding positioning, all in a safe, convenient and economical manner. In this regard, the present invention substantially fulfills this need. SUMMARY OF THE INVENTION In view of the foregoing disadvantages inherent in the known types of ski brake systems of known designs and configurations now present in the prior art, the present invention provides an improved binding/ski brake system. As such, the general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new and improved binding/ski brake system and method which has all the advantages of the prior art and none of the disadvantages. To attain this, the present invention essentially comprises a binding/ski brake system. First provided is a pair of skis. Each ski has a forward end. Each ski has a longitudinally spaced rearward end. A length is defined

between the forward and rearward ends. The length is between 130 cm and 205 cm. Each ski has an inside edge. Each ski has a laterally spaced outside edge. A width is defined between the inside and outside edges. The width is between 63 mm and 130 mm. Each ski has an upper surface 22. Each ski has a lower surface. Each ski has a longitudinal major centerline. The centerline is provided essentially midway between and parallel with the inside and outside edges. A binding assembly is provided. The binding assembly is positioned on the upper surface of each ski. Each binding assembly has a toe piece. Each binding assembly has a longitudinally spaced a heel piece. Each of the pieces has an inside edge. Each of the pieces has a laterally spaced outside edge. Each binding assembly has a longitudinal minor centerline. The minor centerline extends through the toe and heel pieces. Each minor centerline is spaced from and parallel with the major centerline of its associated ski. Provided next is a brake assembly. The brake assembly is positioned on the upper surface of an associated ski adjacent to the heel piece. Each brake assembly has a fixed plate. The fixed plate is secured to the upper surface of its associated ski forwardly of its associated heel piece. Each fixed plate has an upper surface. Each fixed plate has a lower surface. Each fixed plate has side surfaces. Each brake assembly has a movable plate. The movable plate has an upper surface. The movable plate has a lower surface. The movable plate further has side surfaces. Further provided is a pair of widely spaced forward fingers. A pair of narrowly spaced rearward fingers is also provided. The fingers couple the movable plate to the fixed plate. In this manner the movable plate may be moved between an inoperative position and an operative

position. In the inoperative position, the movable plate is on the upper surface of its associate ski forwardly of the fixed plate. In the operative position the movable plate is above the fixed plate. The forward fingers have upper ends. The upper ends are in an inverted U-shaped configuration. The upper ends are pivotably coupled to the movable plate. The forward fingers have lower ends. The forward fingers have outwardly extending arms . The outwardly extending arms are pivotable with respect to the fixed plate. The outwardly extending arms include a short arm. The short arm extends to the inside edge. The outwardly extending arms include a long arm. The long arm extends to the outside edge. One outwardly extending arm is a short arm extending a first distance to the inside edge of a ski. The other arm is a long arm extending a second distance, greater than the first distance, to the outside edge of a ski. The second distance is between 50 percent greater and 150 percent greater than the first distance. The arms terminate with rearwardly extending braking legs. The rearward fingers terminate with spring fingers. The spring fingers are adapted to be compressed when the movable plate is lowered by the force of a skier' s boot on the movable plate and to expand to raise the movable plate when the skier's boot is removed from the movable plate. The fingers are fabricated of resilient metal. Plastic covers are provided. The plastic covers are positioned over the outside ends of the legs. The braking legs are adapted to extend directly rearwardly when the movable plate is in the lowered inoperative position being depressed by a users foot and boot. The braking legs are then adapted to extend rearwardly and downwardly when the movable plate is in the raised operative position in response to a skier's foot and boot becoming separated from its associated binding

assembly and ski. In this manner the braking legs will function to preclude excessive movement of the separated ski from the ski boot and skier. There has thus been outlined, rather broadly, 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 the subject matter of the claims attached.

DESCRIPTION OF THE PREFERRED EMBODIMENT With reference now to the drawings, and in particular to Figure 1 thereof, the preferred embodiment of the new

and improved binding/ski brake system embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described. The present invention, the binding/ski brake system 10 is comprised of a plurality of components. Such components in their broadest context include a brake assembly, a pair of forward fingers and a pair of rearward fingers. Such components are individually configured and correlated with respect to each other so as to attain the desired objective. First provided is a pair of skis 12. Each ski has a forward end 14. Each ski has a longitudinally spaced rearward end 16. A length is defined between the forward and rearward ends. The length is between 130 cm and 205 cm. Each ski has an inside edge 18. Each ski has a laterally spaced outside edge 20. A width is defined between the inside and outside edges. The width is between 63 mm and 130 mm. Each ski has an upper surface 22. Each ski has a lower surface 24. Each ski has a longitudinal major centerline. The centerline is provided essentially midway between and parallel with the inside and outside edges. A binding assembly 26 is provided. The binding assembly is positioned on the upper surface of each ski. Each binding assembly has a toe piece 28. Each binding assembly has a longitudinally spaced a heel piece 30. Each of the pieces has an inside edge 32. Because of the placement, the inside edge of the skier's boot is thus located over the inside edge of the ski. Each of the pieces has a laterally spaced outside edge 34. Each binding assembly has a longitudinal minor centerline. The minor centerline extends through the toe and heel pieces. Each minor centerline is spaced from and parallel with the major centerline of its associated ski.

Provided next is a brake assembly 36. The brake assembly is positioned on the upper surface of an associated ski adjacent to the heel piece. Each brake assembly has a fixed plate 38. The fixed plate is secured to the upper surface of its associated ski forwardly of its associated heel piece. In an alternate embodiment, the fixed plate is attached to the forward area of the heel piece. Each fixed plate has an upper surface 40. Each fixed plate has a lower surface 42. Each fixed plate has side surfaces 44. Each brake assembly has a movable plate 46. The movable plate has an upper surface 48. The movable plate has a lower surface 50. The movable plate further has side surfaces 52. Further provided is a pair of widely spaced forward fingers 54. A pair of narrowly spaced rearward fingers 56 is also usually provided. The fingers couple the movable plate to the fixed plate. In this manner the movable plate may be moved between an inoperative position and an operative position. In the inoperative position, the movable plate is on the upper surface of its associate ski forwardly of the fixed plate. In the operative position the movable plate is above the fixed plate. The forward fingers have upper ends 58. The upper ends are in an inverted U-shaped configuration. The upper ends are pivotably coupled to the movable plate. The forward fingers have lower ends 60. The forward fingers have outwardly extending arms 62, 64. The outwardly extending arms are pivotable with respect to the fixed plate. The outwardly extending arms include a short arm 62. The short arm extends to the inside edge. The outwardly extending arms include a long arm 64. The long arm extends to the outside edge. One outwardly extending arm is a short arm extending a first distance to the inside edge of a ski. The other arm is a long arm extending a second distance greater than the first distance to the

outside edge of a ski. The arms terminate with rearwardly extending braking legs 66, 68. In an alternate embodiment, a single braking leg is utilized. The present invention contemplates a pair of skis, a left and a right, one of the brakes being the mirror image of the other. The rearward fingers terminate with spring fingers 70. The spring fingers are adapted to be compressed when the movable plate is lowered by the force of a skier' s boot on the movable plate and to expand to raise the movable plate when the skier' s boot is removed from the movable plate. The fingers are fabricated of resilient metal. Plastic covers 72 are provided. The plastic covers are positioned over the outside ends of the legs. The braking legs are adapted to extend directly rearwardly when the movable plate is in the lowered inoperative position being depressed by a users foot and boot. The braking legs are then adapted to extend rearwardly and downwardly when the movable plate is in the raised operative position in response to a skier's foot and boot becoming separated from its associated binding assembly and ski. In this manner the braking legs will function to preclude excessive movement of the separated ski from the ski boot and skier. An alternate embodiment of the invention 100 is shown in Figures 5 and 6. In this embodiment, the fingers are formed of a single, resilient wire 102 is a W-shaped configuration coupling the fixed plate 104 and the movable plate 106. The wire has a short arm 110 and a long a4m 112 with upper bends 1216 contacting the moveable plate between the arms and with a lower bend 118 contacting a ski between the upper bends. The upper and lower bends function as a spring urging the upper plate upwardly. The arms are bent with legs 120 terminating in free ends. Covers are provided over the free ends.

Narrow skis, 63 - 68 mm at the waist, have dominated the ski industry since the beginning. This width performs best on groomed runs, and especially on hard snow and ice. Because of the precise edge control and grip on ice, World Cup racers typically use skis that are 67 or 68 mm wide. The problem with narrow skis is that they lack flotation and are more difficult and tiring to use in soft snow conditions. Mid-Fat skis, from around 70 mm at waist to around 88 mm at waist, are currently the ski of choice for the all mountain skier. These are a compromise in all dimensions, but will give better performance in soft snow than a narrow ski without sacrificing too much edge grip and precision on hard snow. Wide skis, around 80 mm to over 130 mm at waist, are the best tool for soft snow and deep powder. The wider the skis are, the more flotation they deliver, and they make skiing powder easier for everyone. The problem here is that the wider the ski, the more difficult it is to get on edge and control edge angle, making them difficult and tiring to use on hard snow conditions. For the last few years, the ski industry has been selling skis based on the percentage of time one spends on groomed runs vs. ungroomed runs, recommending "mid fat" skis for most skiers. This is a compromise in performance under most snow conditions. For example, a skier who spends approximately 75 percent of his time on groomed runs should opt for a ski in the narrow range of the "mid- fat" category, while a skier who spends 75 percent of his time skiing the back bowls should select something wider. Narrow skis and wide skis are now largely considered to be specialized equipment and are used by the purist seeking optimal performance in one particular type of snow conditions. Many times these skis are used by skiers who own more than one pair of skis.

The off-center mounting on the present invention eliminates the compromise. It gives the skier the edge grip and precision of a narrow ski on hard snow, and the flotation and ease of a wide ski in soft snow. This is done by using a ski from the "wide" category and mounting the bindings off-center to position the inside edges of the ski boots over the inside edges of the skis. The reason that this works is because when skiing hard snow, 90 percent of a skiers edging power comes from the downhill ski--the inside edge. Mounting the bindings in this manner allows the skier to edge the skis easily and precisely on hard snow and ice--they ski and feel just like narrow skis. Yet, when skiing powder, they float and feel just like wide skis, because they are side skis! No compromises. As to the manner of usage and operation of the present invention, the same should be apparent from the above description. Accordingly, no further discussion relating to the manner of usage and operation will be provided. With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention. Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction

and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
