Abstract
In a physical exerciser of the push and pull type in which an elongate telescopic system is contractable against the force of a spring by pushing handles together or by pulling apart tension elements connecting the handles, the improvement that the ends of the tension elements pass round guide pulleys and are connected to loops so that additional exercises and greater movements can be performed by pulling on the loops with the hands or feet.
Claims6
A physical exerciser for push and pull exercises comprising:
- an elongate telescopic system having ends, said system being contractable longitudinally by the application of manual pressure;
- resilient biasing means arranged to resist said longitudinal contraction of said system;
- a pair of flexible substantially inextensible tension means, said tension means extending longitudinally on opposite sides of the system and connecting said ends of said sytem so that pulling apart of said tension means on opposite sides of said system contracts said system against said biasing means;
- said tension means having ends, at least two guide members associated with at least two of said tension means ends, said at least two ends each passing round an associated one of said guide members;
- at least two stop means, one attached to each of said at least two ends and each acting to restrain that end from moving inwards round its associated guide member;
- and a separate unrestrained pull member connected to each of said at least two ends, such that pulling on a pull member moves the tension means connected thereto around the guide member to contract the system.

A physical exerciser for push and pull exercises comprising:
- an elongate telescopic system having ends, the telescopic system having a normal extended position, said system being contractable longitudinally by the application of manual pressure;
- resilient biasing means arranged to resist said longitudinal contraction of said system;
- a pair of flexible substantially inextensible tension means, said tension means extending longitudinally on opposite sides of the system and connecting said ends of said system so that pulling apart of said tension means on opposite sides of said system contracts said system against said biasing means;
- at least two guide members each mounted adjacent an end of the system, said tension means having parts adjacent said ends of the system passing around the guide members, at least two stop means attached to the tension means, so that they are adjacent said parts passing around the guide members in said extended position, each stop member acting in said position to restrain the associated tension means from moving inwards around the associated guide member, and at least two separate unrestrained pull members connected to said tension means adjacent said stop members such that pulling on a pull member moves the associated tension means connected thereto around the guide member to contract the system.
