Jumping assist system

In combination with a foot having a bottom surface with a heel located rearwardly and a top surface with a dorsum located forwardly, forwardly of said heel is a ball with an arch interconnecting said heel and said ball, a lower leg including an achilles tendon extending vertically from said heel, said lower leg including a shin, said achilles tendon located at the rear of said leg with said shin located at the front of said leg, a shoe having a sole and an outer covering, an angle brace anchored in said sole of said shoe having a horizontal section extending from under said ball of said foot rearwardly towards said heel, said horizontal section contouring said arch and encasing said heel referred to as a heel cup, a vertical section extending vertically adjacent said achilles tendon forming with said horizontal section a right angle support brace, when said lower leg moves forwardly into a jump-ready position the distance between said lower leg and said vertical section increases, said angle brace serving to support and guide a dorsum tension brace which is flexible but non-elastic, said dorsum tension brace being anchored at said vertical section of said angle brace contouring said heel cup and extending under said horizontal section in said sole of said shoe to said ball, said dorsum tension brace at said ball branching into two straps surrounding said outer covering of said shoe, said straps being anchored at said dorsum.

In combination with an ankle and a foot attached to the lower leg of a human at an ankle joint, said lower leg having a front section defined as a shin and rear section which includes an achilles tendon, an achilles area located directly adjacent said achilles tendon, said foot having a bottom surface with a ball located forwardly and a heel located rearwardly with an arch located therebetween, the forward top portion of said foot being defined as the dorsum, said foot being movable at said ankle joint upward forming an acute angle with said lower leg in a jump-ready position where said foot still rests against a supporting surface, said foot to be movable downward forming an obtuse angle with said lower leg in a lift-off position when said heel is spaced from the supporting surface, with said foot in said jump-ready position said shin moves forwardly toward said foot which lengthens said achilles tendon, jumping height is increased the faster said achilles tendon contracts which moves said foot downward into said lift-off position, a jumping assist system for the human comprising:

• an achilles tension brace consisting of a flexible member extending in a direction parallel to said bottom surface from said shin to said achilles area and also having a portion extending in a direction approximately perpendicular to said bottom surface to a heel sling which surrounds said bottom surface in the area of said heel, a pulling force being applied by said achilles tension brace upward on said heel when said shin moves forward in said jump-ready position tending to move said foot from said jump-ready position to said lift-off position which assists the human in jumping to a greater height when compared to the height obtained by the human without using said jumping assist system.

In combination with an ankle and a foot attached to the lower leg of a human at an ankle joint, said lower leg having a front section defined as a shin and rear section which includes an achilles tendon, an achilles area located directly adjacent said achilles tendon, said foot having a bottom surface with a ball located forwardly and a heel located rearwardly with an arch located therebetween, the forward top portion of said foot being defined as the dorsum, said foot being movable at said ankle joint upward forming an acute angle with said lower leg in a jump-ready position where said foot still rests against a supporting surface, said foot to be movable downward forming an obtuse angle with said lower leg in a lift-off position when said heel is spaced from the supporting surface, with said foot in said jump-ready position said shin moves forwardly toward said foot which lengthens said achilles tendon, jumping height is increased the faster said achilles tendon contracts which moves said foot downward into said lift-off position, a jumping assist system for the human comprising:

• an achilles tension brace consisting of a flexible member extending in a direction parallel to said bottom surface from said shin to said achilles area and also having a portion extending in a direction approximately perpendicular to said bottom surface to a heel sling which surrounds said bottom surface in the area of said heel, a pulling force being applied by said achilles tension brace upward on said heel when said shin moves forward in said jump-ready position tending to move said foot from said jump-ready position to said lift-off position which assists the human jumping to a greater height when compared to the height obtained by the human without using said jumping assist system;
• and
• a dorsum strap encasing said dorsum, said dorsum strap being integrally connected to a flexible dorsum tension brace, said flexible dorsum tension brace extending under said bottom surface from said ball to said heel and upwards to connect at said achilles area such that any expansion pressure on said foot or forward movement at said achilles area will create added tension thus exerting a force downward at said dorsum and upwards at said heel and said arch.

In combination with an ankle and a foot attached to the lower leg of a human at the ankle joint, said lower leg having a front section defined as a shin and rear section defined as an achilles area, said foot having a bottom surface with a ball located forwardly and a heel located rearwardly with an arch located therebetween, the forward top portion of said foot being defined as the dorsum, said foot being movable at said ankle joint upward forming an acute angle with said lower leg in the jump-ready position and then downward forming an obtuse angle with said lower leg in the lift-off position, with said foot in said jump-ready position said shin moves forwardly toward said foot which lengthens the achilles tendon which is located in said achilles area, the jumping height is increased the faster the achilles tendon contracts which moves said foot downward into said lift-off position, a jumping system for the human comprising:

• a leg strap extending between said shin and said achilles area, a tension brace located at said achilles area and extending to said bottom surface at said heel, said leg strap being fixed to said achilles tension brace, a pulling force being applied by said achilles tension brace upward on said heel when said shin moves forward in said jump-ready position tending to move said foot from said jump-ready position to said lift-off position which assists the human in jumping to a greater height when compared to the height obtained by the human without using said jumping system;
• a heel sling surrounding said heel, said achilles tension brace being fixedly secured to said heel sling;
• and
• a dorsum strap encasing said dorsum, said dorsum strap being integrally connected to a flexible dorsum tension brace, said flexible dorsum tension brace extending under said bottom surface from said ball to said heel and upwards to connect at said achilles area such that any expansion pressure on said foot or forward movement at said achilles area will create added tension thus exerting a force downward at said dorsum and upwards at said heel and said arch.
