Abstract

An exercising apparatus for removing excess weight in the area of the abdomen of a user and for building the abdominal muscles wherein a roller exerts pressure against the abdomen and provides a massaging action as the user of the apparatus performs sittingup exercises.

Claims

1. An exercising table for massaging the abdomen of the user comprising:

a frame having a base, a plurality of table legs supported on said base at one end and supporting a table top at their other ends, said top supporting the body of a user when lying on his back with his legs bent over one end of the top at his knees, means for attaching the user'"'"''"'"'s legs below his knees to said one end of said frame, L-shaped lever means comprising a pair of legs interconnected at a joint and pivotally attached to said base at one end of said frame at said joint with one leg thereof extending laterally above said top and the other leg extending along the length of said frame beneath said top, a bar pivotally attached to said one leg of said L-shaped lever for extending longitudinally of said frame above said top for supporting a roller, a roller means mounted on said bar for extending laterally of the longitudinal axis of said bar, and a weight attached to said other leg of said L-shaped lever means, said roller means being positionable over the abdomen of a user and rotating therealong toward his hips upon a sitting-up effort of the user, means for limiting the pivotal movement of said bar relative to said lever upon predetermined rotation of said bar relative to said L-shaped lever during a sitting upon movement of the user, whereby said weight on said L-shaped lever means upon rotation of said bar applies a reactive downward force to said roller means.

2. The exercising table set forth in claim 1 in further combination with:

means for causing movement of said roller means laterally of said bar upon rotation of said roller.

3. The exercising table set forth in claim 1 wherein:

said L-shaped lever means comprises a pair of L-shaped members each comprising a pair of interconnected legs, each member being pivotally mounted on a common end of said frame at opposite sides thereof at a point adjacent the interconnection of its legs, one leg of each of said members extending above said top at said common end of said frame and the other leg of each of said members extending along the length of said frame beneath said top, a pair of bars one pivotally attached to said one leg of each of said members for extending longitudinally of said top for each supporting an end of said roller means, said roller means rotating between the bars upon sitting up effort of the user, and a weight attached to each of the other legs of said members.

4. The exercising table set forth in claim 1 in further combination with:

means for causing movement of said roller means laterally of said bar upon rotation of said roller means.

5. The exercising table set forth in claim 3 in further combination with:

a pair of second weights one attached to a different end of said roller means.

6. The exercising table set forth in claim 3 wherein:

said roller means comprises a shaft fixedly mounted to extend between the bars, and a hollow roller rotatively mounted on said shaft.

7. The exercising table set forth in claim 6 wherein:

said shaft is provided with spiral keyway extending around and along its length, and the inside periphery of said roller is provided with a key for engaging said keyway for causing said roller to move longitudinally of said shaft upon rotation of said roller.

8. The exercising table set forth in claim 7 wherein:

said means for actuating said shaft laterally of the bars comprises a motor for rotating an off center cam, and means for rotating said shaft longitudinally thereof in relationship to the movement of said off center cam.

9. The exercising table set forth in claim 3 wherein:

said roller means comprises a shaft rotatably mounted on and between the bars, a roller mounted on said shaft for rotation thErewith, and a means for activating said shaft and roller laterally of the bars.

10. The exercising table set forth in claim 3 wherein:

said roller means is detachably mounted at one of a plurality of positions along the length of the bars.

11. The exercising table set forth in claim 1 wherein:

said top is divided into two portions at a point along its length, means for hingedly connecting each of said portions together, one of said portions over which the user bends his legs being fixedly positioned on said table legs of said frame, and means for supporting said other portion in one of a plurality of angular positions relative to said first portion.
