Abstract
Abstract An exercising device comprises a rod having handgrips fixed at each end and a pair of intermediate handgrips slidable on the rod. Each of the handles has substantially the same external configuration. Coil compression springs are disposed between one of the fixed handgrips and the adjacent slidable handgrip, and between the two slidable handgrips. By the selection of handgrips, the user can exert compressive force against one or both springs, or tensile force against one or both springs. Two different spring strengths in each direction are thus available and when the springs themselves are of different strengths, then three different spring strengths are available in each direction.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
205 words
An exercising device comprising: a rod having opposite ends; a first handgrip fixedly secured to one end of said rod; a second handgrip fixedly secured to the opposite end of said rod; first movable handgrip means slidably disposed on said rod for movement thereon intermediate said first and second handgrips; second movable handgrip means slidably disposed on said rod intermediate said first movable handgrip means and said second handgrip for movement by a user into abutting relationship with said second handgrip during an exercise program; said first and second movable handgrip means being substantially similar in external configuration to the external configuration of said first and second handgrips; first compression spring means mounted on said rod intermediate said first handgrip and said first movable handgrip means for urging said first movable handgrip means away from said first handgrip along said rod; and second compression spring means mounted on said rod intermediate said first movable handgrip means and said second movable handgrip means for urging said first movable handgrip means toward said first handgrip along said rod against the urging of said first compression spring means, and for urging said second movable handgrip means along said rod toward and into abutting relationship with said second handgrip.
Claim 2
Dependent Claim
205 words
An exercising device comprising: a rod having opposite ends; a first handgrip fixedly secured to one end of said rod; a second handgrip fixedly secured to the opposite end of said rod; first movable handgrip means slidably disposed on said rod for movement thereon intermediate said first and second handgrips; second movable handgrip means slidably disposed on said rod intermediate said first movable handgrip means and said second handgrip for movement by a user into abutting relationship with said second handgrip during an exercise program; said first and second movable handgrip means being substantially similar in external configuration to the external configuration of said first and second handgrips; first compression spring means mounted on said rod intermediate said first handgrip and said first movable handgrip means for urging said first movable handgrip means away from said first handgrip along said rod; and second compression spring means mounted on said rod intermediate said first movable handgrip means and said second movable handgrip means for urging said first movable handgrip means toward said first handgrip along said rod against the urging of said first compression spring means, and for urging said second movable handgrip means along said rod toward and into abutting relationship with said second handgrip.
Claim 3
Dependent Claim
21 words
An exercising device as defined in claim 1 wherein said first and second compression spring means are of different compression strengths.
