Platform exercise apparatus with spring tensioned arm and leg exercise assemblies

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Referring to FIG.
1 there is shown a rectangular platform 10 which may be made from plywood or other rigid material and which is preferably padded to as to form a comfortable mat.
Alternatively the platform 10 may be made of a metal or wood frame having a foam rubber or other type of mat material formed around the frame and covering the central area defined by the frame so as to provide a soft comfortable matter upon which the user can lie down while exercising.
Connected with the platform 10 are arm exerciser members 12 and 14 and leg and abdominal exerciser member 16.
These members are pivotably connected to the platform 10 in any desired manner.
As shown herein, each arm exerciser member 12 and 14 consists of a short flat arcuate end piece 18 and an elongated rectangular piece 20 connected to the end piece 18 by means of a hinge 22.
The end of the rectangular piece 20 opposite the hinge 22 is provided with hand grip means 24 which may simply be a loop in the shape of a horseshoe formed from a plastic, metal or fabric type material.
The arm exerciser members 12 and 14 are connected to the platform 10 at opposite sides of the rectangular platform 10 approximately one fourth of the distance from an end of the platform 10 by means of a pivot pin 26 which extends through a countersunk hole in the arcuate end piece 18 of the exerciser member and through a countersunk hole in an extension 28 of the platform 10.
In this manner the arm members 12 and 14 can be pivoted about the pivot pin 26 in the horizontal plane and about the hinge 22 in the vertical plane.
Tension means, such as springs 30 and 32 are each connected to an edge of the rectangular piece 20 of the arm exercise member and to an edge of the platform 10 spaced from the platform extension 28 to provide tension for operating the arm exerciser member 12 and 14.
The leg and abdomen exercise member 16 is connected to the platform 10 at a point on the long axis of the platform 10 and spaced somewhat from the end of the platform 10 distal from the arm exercise members 12 and 14
