Pneumatic home fitness center

Claim 2

A home fitness center comprising a supporting base, an upright pillar mounted on said base in rigid relation thereto, a sleeve vertically slidable on the pillar, means locking the sleeve in vertically adjusted position on the pillar, an elongated lever arm pivotally mounted on said sleeve for pivotal movement about a generally horizontal axis, handle means on the end of the lever arm remote from the sleeve to enable the lever arm to be pivoted in relation to the sleeve, and means interconnecting the sleeve and lever arm to resist pivotal movement of the lever arm in relation to the sleeve, said means including air cylinder means pivotally connected to the sleeve and pivotally connected to the lever arm in spaced relation to the pivotal connection between the lever arm and sleeve for resisting pivotal movement of the lever arm and means varying air pressure in the air cylinder means to vary the resistance to movement of the lever arm, said means for varying the air pressure in the air cylinder means including a compressor having an air hose connected with the air cylinder means, a control switch on the sleeve for operating the compressor to raise the air pressure to increase resistance to the lever arm and control means on the sleeve for releasing air pressure from the air cylinder means to reduce pressure in the air cylinder means to reduce resistance to pivotal movement of the lever arm.

Claim 3

The structure as defined in claim 1 together with an air pressure guage on the sleeve communicating with the air cylinder means to indicate the air pressure in the air cylinder means and therefore indicate the resistance to movement of the lever arm.

Claim 4

The structure as defined in claim 2 wherein said air cylinder means includes a pair of air shock absorbers having a flexible rubber bag incorporated therein with the rubber bag being inflatable and deflatable by operating the switch for the compressor and operating the control means for discharging air from the air chambers.

Claim 5

The structure as defined in claim 3 wherein said base includes a longitudinally extending beam having an upright support spaced from the pillar, a bench connected to the upright support and connected to the pillar below the sleeve to enable movement of the lever arm when occupying the bench, said bench and pillar including an adjustable connecting means to enable variation of the inclination of the bench in relation to the base and pillar.

Claim 6

The structure as defined in claim 4 together with a leg curl extension device including laterally extending cushioned members for engagement by various components of the legs of a user, means supporting the leg curl extension from the exercise device and cable and pulley means interconnecting the leg curl extension and the lever arm to utilize the lever arm and the air cylinder means to variably resist movement of the leg curl extension.

Claim 7

The structure as defined in claim 5 together with an overhead support member rigid with the upper end of the pillar and including pulleys supported thereon, a cable connected to the lever arm and entrained over the pulleys and depending from the end of the overhead support and provided with a lateral bar to enable variable resistance to movement of the lever arm to be transmitted to the bar for performing various, exercise regimens.

Claim 8

An exercise device comprising a supporting base, an upright pillar means rigidly mounted at one end of said base, a sleeve vertically slidable on the pillar means, means locking the sleeve in vertically adjusted position on the pillar means, an elongated lever arm pivotally mounted on said sleeve adjacent the lower end thereof for pivotal movement about a generally horizontal axis, a transverse handle bar on the end of the lever arm remote from the sleeve to enable the lever arm to be pivoted in relation to the sleeve, and means interconnecting the sleeve and lever arm to resist pivotal movement of the lever arm in relation to the sleeve, said means including air cylinder means pivotally connected to the the upper end portion of said sleeve and pivotally connected to the lever arm in spaced relation to the pivotal connection between the lever arm and sleeve for resisting pivotal movement of the lever arm and means varying air pressure in the air cylinder means to vary the resistance to movement of the lever arm, said base including a longitudinally extending beam having an upright support spaced from the pillar, a bench connected to the upright support and connected to the pillar below the sleeve to enable movement of the lever arm when occupying the bench, a leg curl extension device including laterally extending cushioned members for engagement by various components of the legs of a user, means supporting the leg curl extension from the upright support for said bench and cable and pulley means interconnecting the leg curl extension and the lever arm to utilize the lever arm and the air cylinder means to variably resist movement of the leg curl extension, said means for varying the air pressure in the air cylinder means including a compressor having an air hose connected with the air cylinder means, a control switch for operating the compressor to raise the air pressure to increase resistance to the lever arm and control means for releasing air pressure from the air cylinder means to reduce pressure in the air cylinder means to reduce resistance to pivotal movement of the lever arm, an air pressure guage on the sleeve communicating with the air cylinder means to indicate the air pressure in the air cylinder means and therefore indicate the resistance to movement of the lever arm, said air cylinder means including a pair of air cylinders having a flexible rubber bag incorporated therein with the rubber bag being inflatable and deflatable by operating the switch for the compressor and operating the control means for discharging air from the air chambers, said pressure gauge being mounted on said sleeve between said air cylinders for easy observation by an occupant on the bench.

Claim 9

An exercise device comprising a supporting base, an upright pillar means rigidly mounted at one end of said base, a sleeve vertically slidable on the pillar means, means locking the sleeve in vertically adjusted position on the pillar means, an elongated lever arm pivotally mounted on said sleeve adjacent the lower end thereof for pivotal movement about a generally horizontal axis, a transverse handle bar on the end of the lever arm remote from the sleeve to enable the lever arm to be pivoted in relation to the sleeve, and means interconnecting the sleeve and lever arm to resist pivotal movement of the lever arm in relation to the sleeve, said means including air cylinder means pivotally connected to the the upper end portion of said sleeve and pivotally connected to the lever arm in spaced relation to the pivotal connection between the lever arm and sleeve for resisting pivotal movement of the lever arm and means varying air pressure in the air cylinder means to vary the resistance to movement of the lever arm, said base including a longitudinally extending beam having an upright support spaced from the pillar, a bench connected to the upright support and connected to the pillar below the sleeve to enable movement of the lever arm when occupying the bench, a leg curl extension device including laterally extending cushioned members for engagement by various components of the legs of a user, means supporting the leg curl extension from the upright support for said bench and cable and pulley means interconnecting the leg curl extension and the lever arm to utilize the lever arm and the air cylinder means to variably resist movement of the leg curl extension, said means for varying the air pressure in the air cylinder means including a compressor having an air hose connected with the air cylinder means, a control switch for operating the compressor to raise the air pressure to increase resistance to the lever arm and control means for releasing air pressure from the air cylinder means to reduce pressure in the air cylinder means to reduce resistance to pivotal movement of the lever arm, an air pressure guage on the sleeve communicating with the air cylinder means to indicate the air pressure in the air cylinder means and therefore indicate the resistance to movement of the lever arm, said air cylinder means including a pair of air cylinders having a flexible rubber bag incorporated therein with the rubber bag being inflatable and deflatable by operating the switch for the compressor and operating the control means for discharging air from the air chambers, said pressure gauge being mounted on said sleeve between said air cylinders for easy observation by an occupant on the bench.
