ABSTRACT:
A collapsible rebound exercise apparatus (10) as a resilient, flexible mat (12) capable of forming a substantially planar surface when an associated frame (14) supporting the mat has an open framework (16) thereof disposed in a substantially planar, open position. The framework is provided with two pair of hinges (18, 20) arranged perpendicularly to each other and which permit the framework to first fold symmetrically in overlying relation on itself, and subsequently to collapse on itself by pivotal movement perpendicular to the folding movement. Once folded and collapsed, the framework and associated mat form a generally rectangular package which can be placed in a suitable container, such as a flexible bag (32), for storage and transport.
