Abstract

An in-place exerciser for step aerobic exercise and the like has a base with a cavity defining a receptacle and having a floor. The exerciser also includes a rebound structure with a rigid frame defining a closed loop that corresponds substantially to the size and shape of the receptacle and a sheet of flexible, resilient trampoline material whose edge margin is secured directly to the frame so that the sheet is stretched tightly on the frame. The rebound structure is seated in the receptacle so that said sheet is substantially flush with the top of the base and spaced above said floor of the receptacle.

Claims

1. An in-place exerciser comprising:

a base having an open top, a bottom and incline side walls and defining a generally rectangular receptacle;

an inside shelf formed in the base, said shelf extending all around the receptacle between said top and bottom of the base, and

a rebound structure, said rebound structure including a rigid, generally rectangular, tubular frame defining a closed loop that corresponds substantially to the size and shape of the receptacle, a sheet of flexible resilient trampoline material, said material having edges all of which are wrapped around said frame all around the sheet, and securing means for securing the edge margin of said sheet to portions of the sheet inboard said frame so that the sheet is stretched tight on the frame, the thickness of said rebound structure being substantially the same as the distance between said shelf and the top of the base so that when the rebound structure is seated on the shelf, said sheet is supported all around and is substantially flush with the top of the base and spaced above the bottom of the base.

2. The exerciser defined in claim 1 wherein said sheet is divided lengthwise into a plurality of different color blocks.

3. The exerciser defined in claim 1 wherein said base and said frame are of a rigid plastic material.
