Abstract
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.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
180 words
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.
Claim 2
Independent Claim
180 words
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.
Claim 3
Independent Claim
185 words
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.
Claim 4
Independent Claim
185 words
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.
Claim 5
Dependent Claim
34 words
An apparatus as claimed in claim 2, wherein said flexible divider walls are separated at the center of the enclosure and held there by resilient connectors to maintain the separated flexible divider walls taut.
Claim 6
Dependent Claim
38 words
An apparatus as claimed in claim 2, having game netting above and in alignment with at least one of said flexible divider walls so that a ball can be passed over said netting from one compartment to another.
Claim 7
Dependent Claim
20 words
An apparatus as claimed in claim 2, wherein said flexible divider walls intersect said outer wall at substantially right angles.
