Leg and hip exercising apparatus

Claim 2

An exercise machine comprising; a frame; a rotatable pulley means mounted to the frame; cable means wound in opposite directions about the pulley means so that as the pulley means is rotated in either a clockwise or counter-clockwise direction said cable means is both unwound from and wound onto said pulley means; weight resistive means; means for interacting said cable means with said weight resistive means such that a resistive force can be provided when said pulley means is rotated in either a clockwise or counter-clockwise direction from an initial static position; and means interacting with said pulley means for engagement by a user to apply a rotative force to the pulley means, to overcome the resistive force.

Claim 3

An exercise machine as in claim 1 wherein said weight resistive means comprises a weight stack, said means interacting said cable means with said weight stack comprising a selector shaft for carrying said weight stack and means for coupling said cable means to said selector shaft such that as the cable means is unwound and wound onto said pulley means said selector shaft is raised and/or lowered.

Claim 4

The machine of claim 1 wherein said cable means comprises two separate lengths each wound around said pulley means in a direction opposite to the other, the other end of of each cable length being coupled to said resistive means.

Claim 5

A machine as in claim 3 wherein said weight resistive means comprises a weight stack, said means interacting said cable means with said weight stack comprising a selector shaft for carrying said weight stack and means for coupling the other end of each said cable length to said selector shaft such that as the respective cable length is reeled in the selector shaft is raised to raise the weight stack.

Claim 6

A machine as in claim 4 wherein said coupling means for the other end of each cable length comprises a lifting bar to which said selector shaft is attached, and means at the other end of each cable length for engaging said lifting bar.

Claim 7

A machine as in claim 5 wherein said engaging means to the other end of each cable length comprises a counterweight which also keeps the cable length taut.

Claim 8

The machine of claim 1 wherein said means for applying a rotative force to said pulley comprises a crank arm connected to said pulley means.

Claim 9

An exercise machine as in claim 7 wherein said crank arm extends outwardly at an angle from said pulley means, such crank arm having a free end for engagement by the user.

Claim 10

An exercise machine as in claim 8 further comprising means for adjusting the height of the user engaging each of said crank arms relative to said pulley means.

Claim 11

An exercise machine as in claim 9 further comprising means for adapting the angular rotational position of said crank arm relative to said pulley means.

Claim 12

A leg and hip exercising apparatus comprising: a frame having a horizontal base and a vertical section; a pulley mounted to the frame; two cables, one end of each secured to the pulley such that the cables can be wound in opposite directions about the pulley, the other end of each cable terminating in a vertically traveling counterweight and cable stop: a plurality of stackable weights, slidably mounted to the frame; a lifting bar slidably mounted to the frame, having two separate apertures for surrounding the cables, positioned directly above the cable stops, each aperture being large enough to allow passage of the cable but not large enough to allow passage of the cable stop, said lifting bar additionally having means for incrementally securing said weights thereto; and means for applying a rotative force to the pulley, sid rotative force applied in either a clockwise or counter-clockwise direction resulting in one cable being wound off the pulley, and its respective counterweight and cable stop being lowered in response to gravity, and the other cable being wound onto the pulley, its respective counterweight and cable stop being raised until said cable stop contacts the lifting bar and any additional stacked weights secured thereto, at which point the rotative force must be increased by an amount equal to the downward force applied by the lifting bar to the rising counterweight.

Claim 13

A leg and hip exercising apparatus comprising: a frame having a horizontal base and a vertical section; a pulley mounted to the frame; two cables, one end of each secured to the pulley such that the cables can be wound in opposite directions about the pulley, the other end of each cable terminating in a vertically traveling counterweight and cable stop: a plurality of stackable weights, slidably mounted to the frame; a lifting bar slidably mounted to the frame, having two separate apertures for surrounding the cables, positioned directly above the cable stops, each aperture being large enough to allow passage of the cable but not large enough to allow passage of the cable stop, said lifting bar additionally having means for incrementally securing said weights thereto; and means for applying a rotative force to the pulley, sid rotative force applied in either a clockwise or counter-clockwise direction resulting in one cable being wound off the pulley, and its respective counterweight and cable stop being lowered in response to gravity, and the other cable being wound onto the pulley, its respective counterweight and cable stop being raised until said cable stop contacts the lifting bar and any additional stacked weights secured thereto, at which point the rotative force must be increased by an amount equal to the downward force applied by the lifting bar to the rising counterweight.

Claim 14

The exercising apparatus of claim 11 additionally comprising a platform on the horizontal base and a handlebar on the vertical frame section.

Claim 15

The exercising apparatus of claim 11 wherein said means for applying a rotative force to said pulley comprises a crank rotatably mounted to said pulley, said crank comprising an extendable arm terminating in a padded roller.

Claim 16

The exercising apparatus of claim 3 wherein said means for applying a rotative force to said pulley comprises a crank rotatably mounted to said pulley, said crank comprising an extendable arm terminating in a padded roller.

Claim 17

The exercising apparatus of claim 5 wherein said means for applying a rotative force to said pulley comprises a crank rotatably mounted to said pulley, said crank comprising an extendable arm terminating in a padded roller.

Claim 18

The exercising apparatus of claim 5 further comprising a platform and a handlebar, each mounted to said frame.
