Abstract
Abstract An exercising apparatus in which a handle is connected at one end of a flexible elastic strand such as nylon, the opposite end portion of the strand being supported by a base having spaced stationary abutments thereon adapted to be frictionally engaged by the strand when tensile stress is applied to the latter through the handle. The apparatus is further characterized by a frictionally engaged second strand for damping the return of the first strand from its stressed elongated position to its initial unstressed contracted position.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
124 words
An exercising apparatus comprising a relatively flat base for supporting the user thereon, a flexible elastic strand having one end thereof conneCted to said base, an elongated bar adapted to be grasped by the user at longitudinally spaced points, said bar having one end thereof terminating at and connected to the other end of said strand whereby the latter will yieldingly transmit stress from said bar to the base when the grasped bar is moved upwardly and means for damping the return of said strand from an elongated stressed position to its initial contracted unstressed position, said damping means including a second strand supported by said base and having a relatively greater elasticity than said first strand, and means frictionally engaging said second strand.
Claim 2
Dependent Claim
124 words
An exercising apparatus comprising a relatively flat base for supporting the user thereon, a flexible elastic strand having one end thereof conneCted to said base, an elongated bar adapted to be grasped by the user at longitudinally spaced points, said bar having one end thereof terminating at and connected to the other end of said strand whereby the latter will yieldingly transmit stress from said bar to the base when the grasped bar is moved upwardly and means for damping the return of said strand from an elongated stressed position to its initial contracted unstressed position, said damping means including a second strand supported by said base and having a relatively greater elasticity than said first strand, and means frictionally engaging said second strand.
Claim 3
Dependent Claim
61 words
Exercising apparatus as defined in claim 1 and further comprising means on said base for supporting for longitudinal movement a length of said first strand adjacent its base connected end, said last-named means including a plurality of spaced stationary abutments frictionally engaged by and subdividing said last-named strand length into a plurality of shorter lengths angularly disposed relative to one another.
Claim 4
Dependent Claim
124 words
An exercising apparatus comprising a relatively flat base for supporting the user thereon, a flexible elastic strand having one end thereof fixedly connected to said base, an elongated bar adapted to be grasped by the user at longitudinally spaced points, said bar having one end thereof terminating at and connected to the other end of said strand, and means carried by said base and disposed substantially in a plane parallel to the upper surface of the base for supporting for longitudinal movement a length of said strand adjacent its fixed end portion, said strand supporting means including a plurality of spaced stationary abutments frictionally engaged by and subdividing said last-named strand length into a plurality of shorter lengths angularly disposed relative to one another.
Claim 5
Dependent Claim
124 words
An exercising apparatus comprising a relatively flat base for supporting the user thereon, a flexible elastic strand having one end thereof fixedly connected to said base, an elongated bar adapted to be grasped by the user at longitudinally spaced points, said bar having one end thereof terminating at and connected to the other end of said strand, and means carried by said base and disposed substantially in a plane parallel to the upper surface of the base for supporting for longitudinal movement a length of said strand adjacent its fixed end portion, said strand supporting means including a plurality of spaced stationary abutments frictionally engaged by and subdividing said last-named strand length into a plurality of shorter lengths angularly disposed relative to one another.
