Spring exercise device
First Claim
1. A resistance-type exerciser comprising pivotally interconnected arms having a pair of more closely spaced handle forming ends and a pair of less closely spaced handle forming ends and a caliper-type spring unit for replaceable receipt on the arms for urging respective ends of the arms away from one another, the spring unit comprising a pair mating limbs in the form of telescopic channel-section members, pin means pivotally interconnecting the limbs, and a spring connected between the limbs urging the limbs apart, wherein the limbs are receivable in respective pocket means formed on inner surfaces of the respective arms for retention therein through pressure exerted by the spring.

Abstract
A resistance-type exerciser has pivotally interconnected arms with a more closely spaced pair of handle forming ends and a less closely spaced pair of handle forming ends. A caliper-type spring unit is replaceably fitted to the arms to urge the less closely spaced pair of ends apart. The spring unit can be readily replaced with another unit of different spring pressure so as to vary the resistance of the exerciser. The exerciser is used by pushing the less closely spaced ends toward one another against the spring pressure or by pulling the more closely spaced ends apart.

8. In a resistance-type exerciser comprising pivotally interconnected arms having a pair of more closely spaced handle forming ends and a pair of less closely spaced handle forming ends, and spring means urging one of said pair of ends apart and the other of said pair of ends toward one another, the improvement wherein said spring means comprises a caliper-type spring unit detachably associated with said arms, the spring unit having a pair of limbs, a pivot pin pivotally interconnecting the limbs, and a coil spring coaxially received on the pivot pin, the coil spring having extended ends for applying spring pressure on the limbs, the respective limbs of the spring unit being associated with the respective arms of the exerciser for urging the respective pairs of ends of the arms apart and toward one another as aforesaid and the pivot pin of the spring unit being located substantially on a pivot axis of the arms.
- 15. A resistance-type exerciser comprising a pair of arms, means forming a pivotal connection between the arms intermediate the ends thereof with the arms shaped to provide a pair of more closely spaced handle forming ends and a pair of less closely spaced handle forming ends, and spring means associated with the arms for urging the less closely spaced ends apart and the more closely spaced ends toward one another, wherein the spring means comprises a caliper-type spring unit detachably associated with the exerciser, the spring unit having pivotally interconnected limbs associated with the respective arms and a spring for exerting pressure on the respective limbs effective for urging the opposite ends of the arms respectively apart and toward one another as aforesaid, wherein the limbs of the spring unit comprise mating telescopic channel-section members, and the unit includes a locking pin for insertion laterally through openings in the webs of the respective limbs for releasably retaining the limbs in closed telescoped position counteracting the force of the spring.
