A jogging apparatus comprising a tubular frame, an elastomeric member bonded to the frame and a mat bonded to the elastomeric member when the elastomeric member is preloaded radially inwardly so that when the load on the elastomeric member is released, the mat is tightly stretched on the frame to provide the jogging surface. Circumferentially spaced legs are pivoted to the inner surface of the frame and which, in operative position, have portions extending radially outwardly and downwardly and which are foldable inwardly within the plane of the jogging apparatus. The legs are mounted by a construction which tends to urge the legs yieldingly outwardly when they are extended and tends to urge the legs yieldingly inwardly when they are folded inwardly.

DETAILED DESCRIPTION What is claimed is: 1.
A jogging apparatus comprising an annular frame defining an opening, an elastomeric annular body bonded to said frame, a mat bonded to said elastomeric body and covering the opening in said frame such that the mat is yieldingly supported on said frame, said elastomeric body being hollow in cross section and comprises a top wall, a bottom wall and inner and outer side walls, said elastomeric body, in the unloaded and undeformed state, assumes a configuration such that the inner wall and outer wall extend upwardly and outwardly and, in the deformed state with the mat attached to the top wall, assumes a configuration such that the inner wall and outer wall are deflected radially inwardly such that they are generally vertical and the mat is stretched such that the elastomeric body is self-sustaining and having a configuration such that it is free to deflect in shear deformation radially inwardly upon downward movement of the mat, and means for supporting said frame in spaced relation to a supporting surface.
2.
The jogging apparatus set forth in claim 1 wherein said frame has a long and short axis.
3.
The jogging apparatus set forth in claim 2 wherein said frame is tubular.
4.
The jogging apparatus set forth in claim 1 wherein said elastomeric body is made of a resilient material having a durometer of 40 to 60 on the A scale.
5.
The jogging apparatus set forth in claim 1 wherein said elastomeric body includes an integral portion overlying and bonded to the portion of the mat bonded to the elastomeric body.
6.
The jogging apparatus set forth in claim 1 wherein said elastomeric body includes an integral inwardly and upwardly extending peripheral lip that extends from the area of juncture of the top wall and outer side wall when the body is in the unstressed condition and is bonded to the top of said mat.
7.
The jogging apparatus set forth in claim 6 wherein said elastomeric body includes an integral upstanding annular bead extending upwardly from the bottom between the inner and outer side walls
