Abstract
An isometric exercise apparatus of the sit-down type having a base and in which footrests carried by a first post pivoted on the base enable isometric resistance to pulling or pushing on a second post intermediately pivoted at the user's seat, the second post being linked to the first post in alternate arrangements of a common link, depending on which muscles are to be exercised.
Claims10
An isometric exercise apparatus having a base, a seat, a seat pedestal, supporting said seat on said base seat, a first endwise pivoted post spaced a first distance from said seat, a first cross arm on said first post defining a foot rest on either side of said first post arranged for outward foot pressure, a second post spaced a second lesser distance from said seat, having upper and lower portions and pivoted therebetween, a second cross arm on said second post defining a hand rest on either side of said second post arranged for inward or outward arm pressure, said first and second cross arms lying in generally parallel planes, and a link linking said first post to the upper or lower portions of said second post for pulling or pushing force respectively on said second post against the resistance of foot pressure on said first post, said seat pedestal comprising a third post rigidly attached to and extending from said base and a seat support, said second post being pivoted on said seat support.
An isometric exercise apparatus having a longitudinally extended base comprising forward and rearward portions arranged to stably support said apparatus on a floor, said base forward portion having a first pivot mount thereon;
- a seat pedestal fixed to said base rearward portion;
- a seat mounted on said seat pedestal;
- a second pivot mount carried forwardly on said seat pedestal below said seat;
- a first post pivotally mounted endwise to said first pivot mount and extending generally vertically therefrom, said first post having a first post cross arm arranged to receive the feet of a user seated on said seat;
- a second post pivotally mounted intermediate its ends on said second pivot mount and extending generally vertically therefrom in the same vertical plane as said first post, said second post having a second post cross arm generally in a horizontal plane parallel to the horizontal plane of said first cross arm, said second cross arm being arranged to receive the hands of a user, said second post having third and fourth pivot mounts at upper and lower ends thereof respectively;
- a link arm pivotally mounted to said first pivot mount and to said third or fourth pivot mounts alternatively for isometric exercise either by pulling with the arms on said second post cross arm with said link extending between said second post and said third pivot mount or pushing on said second post cross arm with said link extending between said second post and said fourth pivot mount, each while the user's feet push against said first cross arm in isometric resistance to movement of said second cross arm by pulling or pushing respectively, whereby different groups of muscles are exercised in response to location of said link on said first post and the use of pulling or pushing movement of the arms.
