Rotary arm/leg exerciser

摘要

The present invention provides a compact, unitary exercise machine which may be rapidly reconfigured such that the user can perform a variety of exercise routines employing essentially the same rotary exercise movement, whether using the legs or the arms, while simultaneously exercising all the muscles of the subject extremity, including antagonistic muscles.

主权项

1. A rotary arm/leg exerciser, comprising:
a) a base unit with a vertical pole mounted perpendicularly to said base unit; b) a first support sleeve adapted to support a pair of seat support arms disposed outside of said vertical pole and slidably displaceable and fixable with respect to said vertical pole further comprising horizontally disposed first mounting channels adapted to mount said seat support arms affixed on opposing lateral sides of said first support sleeve adapted to support a seat support arm; c) the pair of horizontally disposed seat support arms each with a proximal end and a distal end, the proximal ends of which are slidably displaceable through, and fixable with respect to, one of said first mounting channels adapted to mount said seat support arms; d) a seat with a fixedly reclinable back affixed to the distal ends of said seat support arms; e) a telescopically lengthwise adjustable seat support unit hingedly attached between said seat support arms such that said seat support unit is adapted to be swung down and fixed in a first position in which the long axis of said seat support unit is perpendicular to said seat support arms to support said seat, or swung up and fixed in a second position in which the long axis of said seat support unit is parallel to said seat support arms and between them; f) a second support sleeve adapted to support a pair of rotor support arms disposed outside of said vertical pole and slidably displaceable and fixable with respect to said vertical pole with horizontally disposed second mounting channels adapted to mount said rotor support arms affixed on opposing lateral sides of said second support sleeve adapted to support rotor support arms; g) the pair of horizontally disposed rotor support arms each with a proximal end and a distal end, the proximal ends of which are slidably displaceable through, and fixable with respect to, one of said second mounting channels adapted to mount said rotor support arms; h) a rotary resistance unit comprising a resistance wheel with an axle mounted between, and supported by, two arms of a support yoke wherein the non-bifurcated end of said support yoke is co-axially affixed to a support head;
a. wherein said resistance wheel further comprises a pair of diametrically opposed crank arms each with a proximal end and a distal end, wherein the proximal end of one crank arm is orthogonally affixed at one end of said axle and the proximal end of the other crank arm is orthogonally affixed at the other end said axle, wherein the distal ends of both crank arms are connectable with a one of a multiplicity of interchangeable handles and pedals;b. wherein said support head is affixed to the distal ends of said rotor support arms; and i) a user adjustable means of varying a force required to rotate said resistance wheel.
