Abstract

A portable lightweight body-anchored exercising apparatus for use in exercising the human body made up of a frame, a pair of ropes with free ends pullable by a user, weights for resisting the pulling forces, and a base connected to the frame and on which the user rests his body during performance of exercises to hold the apparatus in place so that it does not move in response to the generally upward forces created by the pulling of ropes by the user. Additionally, the exercising apparatus includes a pulley system to permit the user to move his exercising limbs a distance greater than the excursion of the weights, handles for the user to grasp while pulling the ropes, sheaves for controlling the movement of the ropes, and guide pins for guiding the weights so that they cannot swing outwardly and harm the user. The weights are attached to the ropes with hooks to allow them to move jointly with the ropes.

Claims12

Dependent claims

A portable, body-anchored exercising apparatus, comprising:

(a) an erect vertically elongated rigid frame;
(b) a pair of separate elongated, flexible ropes mounted on and being axially movable along their axes of elongation in relation to the frame at opposite sides thereof, said ropes being capable of being pulled by a user for exercise purposes, and said ropes generating a substantially upward force on the frame when so pulled, each rope of said pair of ropes having a grasp end which when idle is situated at approximately mid-body level of an adult user;
(c) separate means for resisting the pulling forces on the ropes generated by the user;
(d) a pair of separate pulley systems, each pulley system being operatively interposed between a different resistance means and an associated rope, each pulley system including at least two vertically spaced pulleys about which the associated rope is trained, the upper pulley being rotatably supported by the rigid frame and the lower pulley being rotatably supported by the associated rope, the lower pulley supporting the associated resistance means, whereby the apparatus is provided with a mechanical advantage greater than 1 to 1 in favor of the grasp ends, the mechanical advantage allowing the user to move the grasp ends through a distance greater than the distance through which the associated resistance means moves;
and
(e) a base connected to the frame and on which the user rests his body weight while exercising on the same, said base exerting a force opposing the force of the pulled ropes, when the user's weight is applied to said base, said base being operative for permitting the user to hold the apparatus down using his own body weight in any desired position while exercising.

(c) separate means for resisting the pulling forces on the ropes generated by the user;
(d) a pair of separate pulley systems, each pulley system being operatively interposed between a different resistance means and an associated rope, each pulley system including at least two vertically spaced pulleys about which the associated rope is trained, the upper pulley being rotatably supported by the frame and the lower pulley being rotatably supported by the associated rope, the lower pulley supporting the associated resistance means, whereby the apparatus is provided with a mechanical advantage greater than 1 to 1 in favor of the grasp ends, the mechanical advantage allowing the user to move the grasp ends theough a distance greater than the distance through which the associated resistance means moves;
(e) a base connected to the frame and on which the user rests his body weight while exercising on the same, said base exerting a force opposing the force of the pulled ropes, when the user's weight is applied to said base, said base being operative for permitting the user to hold the apparatus down using his own body weight in any desired position while exercising;
(f) said frame further including
(i) a bottom portion attached to said base and
(ii) two erect vertically elongated inverted U-shaped members at opposite sides of the bottom portion,
(ii) each of the inverted U-shaped members having a bottom end mounted on the bottom portion, and a top end.

(f) the exercising apparatus additionally comprising a pair of means for guiding the resistance means along predetermined paths during movement of the resistance means;
and
(g) the pair of guide means being mounted on the frame for movement along the vertical length of the frame.
