Abstract
A structure for use as an exercise compartment and a method for playing a ball game therein is disclosed. The structure has a horizontal rebound surface which is supported above the ground and has means for enclosing the air space above said surface to form a cell, said cell being of a size suitable for enclosing at least one human using said surface as a springboard for exercise or for playing the ball game.
Claims5
An apparatus for use by one or more persons as an exercise game or device, comprising:
- a plurality of adjacent and flexible rebound surfaces upon which a person may jump;
- a flexible outer wall around said rebound surfaces to form an enclosure, said outer wall being positioned within the perimeter of the rebound surfaces to deflect a person jumping on one of the rebound surfaces and to protect the person from being injured;
- flexible dividers for dividing the enclosure into compartments corresponding to the plural rebound surfaces, the dividers being positioned within the perimeter of each of the rebound surfaces to deflect a person jumping on one of the rebound surfaces and to protect the person from being injured;
- a support structure, external to said outer wall;
- resilient couplings connecting said dividers and said external support structure to retain said dividers under tension, wherein said outer wall is attached to said resilient couplings that connect said dividers and said external support structure to reduce the amount said wall can flex upon impact by the person jumping on the rebound surface.

An apparatus for use by one or more persons as an exercise game or device, comprising:
- a plurality of adjacent and flexible rebound surfaces upon which a person may jump;
- a support for said rebound surfaces;
- resilient couplings attaching the rebound surfaces to the support;
- a flexible outer wall around said rebound surface to form an enclosure, said outer wall being positioned within the perimeter of the rebound surfaces to deflect a person jumping on one of the rebound surfaces and to protect the person from being injured by (i) falling from the rebound surfaces, (ii) impacting the resilient couplings or (iii) impacting the support;
- flexible dividers for dividing the enclosure into compartments corresponding to the plural rebound surfaces, said dividers comprising at least one pair of flexible walls spaced apart from one another, the flexible divider wall being positioned within the perimeter of each of the rebound surfaces to deflect a person jumping on one of the rebound surfaces and to protect the person from being injured by (i) entering an adjacent section, (ii) impacting the resilient couplings, or (iii) impacting the support means.
