Abstract: A scalable high-performance bouncing apparatus provides convenient access to untensioned internally semi-mounted springs/tension elements. A holster retains the inoperative semi-mounted elements and avoids contact or friction with fully engaged tension elements. Adjustable connection elements permit compensation for lengthening of spring elements due to creep or elongation set. The connection elements include collars that compress the tension elements, and may be connected to the springs/tension elements by first stretching the elements beyond their working elongation and then placing the collars onto the stretched portions.

Abstract: A scalable high-performance bouncing apparatus provides convenient access to an internally mounted compound tension spring. Semi-mounted internal storage of disengaged tension elements may be provided. The tension elements may be engaged or disengaged through an access feature such as a slot in the apparatus frame. A user's finger or tool may be employed to effect engagement/disengagement. Alternatively, the apparatus may include mechanical components capable of effecting engagement/disengagement. The tension elements may also be part of a cartridge unit that can be wholly removed from the apparatus for engagement/disengagement. The assembly may also include a torque-transmitting bearing and/or a universal foot joint for improved high performance operation.

Abstract: A scalable high-performance bouncing apparatus includes a carriage assembly that can support a person; a foot alternately retracting toward and extending away from the carriage assembly; and a thrust assembly having a tension force and effecting the retraction and extension using a plurality of engageable and disengagable elastomer tension elements that supply the tension force. A shield member integral with the carriage assembly protects the rider from accidental contact with moving parts of the thrust assembly, and an access feature enables engagement and disengagement of the tension elements for adjustment of the tension force. Piston pogo, scissor-lift pogo and scissor-lift bounceboard embodiments are disclosed.
