| WO/2004/000055 | PROTECTIVE ASSEMBLY FOR A LIMB |
| What is claimed is: 1. Golf shoe wherein the outer edge of the shoe is covered with a slippery material which helps the foot to twist. 2. Golf shoe wherein the back part of the shoe has element, like a spike, which is the axis of the foot twist. 3. Golf shoe wherein the outer surface of the sole is placed diagonally to the main sole. 4. Golf shoe wherein there is a splice and connection of belt, to the shoe and hip in the way specified on figure 2b. |
The subject of the invention is α knee-protecting shoe construction technology, which protects the knee of an forward leg during the swing.
Most of the golfing shoes used nowadays are simply a comfortable court shoes equipped with spikes on sole, or other elements increasing foot stability. Such solutions are very successful in preventing slipping. However, they are forcing the golfers' knee to twist in an unnatural way in the last phase of a swing. Such twist, if repeated many times causes, pain and injuries of the forward leg knee.
The essence of the invention is in the usage of a slippery surface on the outer edge of the shoe. Such surface allows the foot to turn. The surface can be equipped with elements which would prevent foot from moving in any direction, other than a turn to the outside.
The turn of the foot would take place around element (2) placed on the back side of the sole of shoe. This element (for example spike) is suppose to be the axis for the foot turn. In the last phase of a swing body weight is transferred to the outer foot edge of the forward leg. The profile of the sole is designed to help moving the body weight to the outer edge of the shoe. Part of the sole, placed on the outer edge of the shoe, is positioned diagonally to the main sole surface.
Shoulders of the golfer, in the end phase of the swing, turns the body, and causes a twist of a knee (Figure 2a). Body weight is moved to the outer edge of the foot, and the shoe is turning around the element (2) on a ground, using the slippery, outer part of the sole (1 ). By that, the injury causing knee twist will be eliminated, and the swing will be modified only slightly, after the hit, in the final phase of the swing.
The belt (4), made out of a non-stretchy material, spliced around the leg: from the hip, to the front and the inner part of the lap, behind the knee, on the outer part of the calf, and attached to the shoe. It will help to move the foot in the desired direction.
Using the shoe and the belt, the knee is fully protected. The initial phases of the swing the golfer is executing with his knee slightly bent. In the last phase of the swing the body weight is moved to the forward leg, the leg becomes straight and the hip is lifted. An accurate length of the belt will provide golfer the comfort of a loose belt in the first phases of the swing, and in the last phase a tight, which will twist the foot.
