TABLE-US-00001 U.S. Patents Patent Number Issue Date Patentee PCT/GB2010/001163 Jul. 12, 2012 Martin Breach US4203235 A May 20, 1980 R. Harrison Van Pelt, Jr.
BACKGROUND OF THE INVENTION
[0002] The act of alpine slalom skiing is one that requires great skill, muscular strength, and coordination. There are many components to alpine skiing that must be executed perfectly to ensure the skier's safety and flawless performance. Many consider the act of placing the majority of one's weight over the top of the ski boots and having the weight be "over the front of the skis" to be simultaneously the hardest yet most important facet of alpine skiing. This position must be maintained throughout the duration of the downhill skiing course so the skier does not fall and is able to execute correct turns and maintain speed. Many beginning and intermediate skiers lean too far back at various difficult portions of a downhill course in an effort to maintain speed and for better control. Contrary to what one might expect, this act of leaning back makes the skier lose control and, in many cases, fall. Because it is a natural instinct to lean back on the skis, it is very hard to teach the proper forward stance for the safety of the skier. It is counter-intuitive to lean forward going down a steep hill. There are many exercises and metaphors that coaches use to try and teach the proper stance, but still many skiers have difficulty maintaining the stance for the duration of the course.
[0003] Therefore, a major problem for downhill skiers, whether they are recreational skiers or racers, is to keep their weight over the forward part of their skis. The dynamic balance of a downhill skier as to the fore/aft (forward and backward) movements is a necessary skill to achieve optimal control of the skis while skiing down steep slopes. It is well understood that one of the greatest obstacles to proper skiing is when the skier places weight on their heels, which transfers weight to the back portion of the skis. When the skier's weight is wrongly placed on the back of the skis, then the skier will lose control of the skis, lose speed, and be unable to edge properly or execute the necessary turns to traverse the ski slopes.
SUMMARY OF THE INVENTION
[0004] Unlike the prior art, which focuses on cumbersome accessories and add on plates that forces the skier to have pressure forward on all terrain, or a balancing membrane under the ski boot which has the same problems, my invention is quite different.
[0005] My device utilizes micro-vibration motors and a pressure switch that I have discovered that the vibrations travel using the soft inside of the ski boot to conduct the vibrations to the skier when needed. Thus, giving the skier continual feedback for all terrain, groomed, ungroomed, powder, steep, medium, and flat.
[0006] It is therefore an object of this invention to provide an inexpensive "add-on" to a ski boot that will alert the skier when their weight is too far back.
[0007] It is a further object of this invention to provide a vibration stimulus utilizing micro-vibration motors in the device with a hinge-lever activator that transfers the vibration from the device to the ski boot. The vibration of the device travels and is transmitted through the ski boot to the heels, thus alerting the skier to maintain the proper forward stance. I have discovered that vibrations aimed directly to the back of the skier's leg is ineffective because it is muffled by thick socks and ski pants.
[0008] Therefore, it is a further object of this invention to incorporate and use existing ski boots to amplify and transfer the vibrations of the device to create a stimulus communicating wrong posture to the skier.
[0009] It is a further object of the invention that the configuration of the device is compact and adjustable such that it clips over the back of various makes of boots.
[0010] It is a further object that the training device is portable and can be taken on or off easily when needed for the convenience and training of the skier. In addition, because of the easy adjustability, it can be transferred from one skier to another for training on steep slopes.
[0011] It is still a further object of this invention to promote safety and prevent a skier from losing control on a steep incline by having their weight too far back. Therefore the device can be placed on the ski boot when going down a steep incline and easily removed for moderate slopes when balance is more evenly distributed.
[0012] It is a further object of this invention to use "off the shelf" inexpensive components such as micro vibration motors, hinge lever, and triple A battery source imbedded in a plastic clip on device that is water resistant, durable, and shock proof.
[0013] It is still a further object of this invention to use a simple velcro safety strap to ensure that the device doesn't come off the ski boot and get lost in a fall.
[0014] These and other objects of the invention are achieved in accordance with the teaching herein in a device that attaches to the back of the ski boot. The device is comprising of a thermoplastic case that attaches to the back lip of the top of the boot. When the hinged lever is activated by pressure being placed on the back of the boot, the device vibrates by way of two micro-vibration motors encased in a thin plastic casing. This vibration is transferred to the boot and alerts the skier that there is too much weight on their heels which is an incorrect stance.
[0015] The power supply and battery pack are conveniently located on the outside of the boot and electrical wires are attached and imbedded in the device as are the vibrating motors and hinge lever.
[0016] The fastening means of the above ski training device is the configuration of an upside down "J" shaped plastic housing wherein the battery pack and bulk of the apparatus is located on the outside part of the boot. The portion of the device that is located inside the boot houses the small vibrating motors and hinge lever. A thin safety strap attaches to the device on the outside of the battery pack and encircles the boot to ensure the device doesn't come off and get lost in the event of a fall.
[0017] Because of the unique configuration of the upside-down "J" shaped snow training device and the ease of adjustment to any boot, it can be easily and quickly removed from the ski boot. This allows the device to be used for steep hills and yet can be removed and is small enough to fit in a ski jacket pocket when not needed. Because the components are embedded in the plastic, it is virtually shock-resistant and waterproof. The portion of the device that houses the vibration motors and hinge lever is thin and small enough so as not to cause discomfort to the skier. The device is also easily adjustable and can be fitted to any standard ski boot by means of a screw adjustment.
[0018] The two vibrating heads are vertically installed and turn unobstructed and are only activated by the hinge lever. As a result of the no-load position, the heads can turn at a maximum speed of thirteen thousand revolutions per minute causing vibrations to travel through the ski boot. As the vibrations are transmitted through the hard plastic of a ski boot, it is easily detectable by a skier as a stimulus to alert the skier to improper weight back distribution. Conversely, when the correct stance is reached there is no vibration which indicates the weight of the skier is forward.
