Abstract
An exercise device designed to work and strengthen abdominal muscles while in a standing position comprises a center tube that forms the main axle of the device. The center tube extends completely through where it forms the left and right gripping handles. A pair of padded rollers is rotatingly supported upon the center tube and are pressed upon and then motioned downwardly and upwardly over a user's quadriceps in a reciprocating manner to exercise the abdominal muscles. A gap between the rollers is provided to allow clearance for the device as it is utilized.
Claims14
An exercise device comprising:
- a central tubular member defining a central axis;
- a first handle and a second handle, each of said handles being formed at opposite ends of said central tubular member;
- a first roller coaxially mounted on said central tubular member so as to rotate freely about said central tubular member;
- a second roller coaxially mounted on said central tubular member so as to rotate freely about said central tubular member, wherein said first and said second rollers are longitudinally spaced apart from one another to form a recessed intermediate section there between;
- and
- four perpendicularly-extending disc-shaped collars mounted on said central tubular member via central opening portions, each of which includes a radial slit which allows expansion of its center opening portion, two of said disc-shaped collars being on opposing sides of said first roller and two of said disc-shaped collars being on opposing sides of said second roller;
- wherein each radial slit allows its respective disc-shaped collar to be selectively positioned along said central tubular member.

An exercise device comprising:
- a central tubular member defining a central axis;
- a first handle and a second handle, each mounted at opposite ends of said central tubular member, being longitudinally movable and each further including a molded gripping area;
- a first roller including a center aperture portion and a first bushing inserted therein being coaxially mounted on said central tubular member;
- a second roller including a center aperture portion and a second bushing inserted therein being coaxially mounted on said central tubular member, wherein said first and said second rollers are longitudinally spaced apart from one another so as to form a recessed intermediate section;
- and
- four perpendicularly-extending disc-shaped collars mounted on said central tubular member via central opening portions, each of which includes a radial slit which allows expansion of its center opening portion, two of said disc-shaped collars being on opposing sides of said first roller and two of said disc-shaped collars being on opposing sides of said second roller;
- wherein each radial slit allows its respective disc-shaped collar to be selectively positioned along said central tubular member.

An exercise device comprising:
- a central tubular member defining a central axis and constructed of a rigid material;
- a first handle and a second handle, each mounted at opposite ends of said central tubular member, being longitudinally movable and each further including a molded gripping area;
- a first roller including a center aperture portion and a first bushing inserted therein being coaxially mounted on said central tubular member;
- a second roller including a center aperture portion and a second bushing inserted therein being coaxially mounted on said central tubular member, said first and said second rollers being longitudinally spaced apart from one another on said central tubular member so as to form a recessed intermediate section there between;
- a first and second disc-shaped collar each having a radial slit and each being coaxially mounted on said central tubular member against opposing side surfaces of said first roller so that they are operatively adapted to slidingly locate and retain longitudinal position of said first roller on said central tubular member;
- and,
- a third and fourth disc-shaped collar each having a radial slit and each being coaxially mounted on said central tubular member against opposing side surfaces of said second roller so that they are operatively adapted to slidingly locate and retain longitudinal position of said second roller on said central tubular member.
