Abstract
An exercise machine that allows essentially unlimited number of lifting exercises to be performed that operates like free weights but with the safety of a universal gym including a single stack of weights connected through a pulley system extending vertically upwardly to a frame and then downwardly along vertical frame members from point locations to connect to two separate connection points on an exercise grasping device all in a single plane wherein movement of either connecting point, lift the weight and an adjustable weight supply device comprising a vertical rod and tube centrally positioned in a vertical hole through the weight stack to allow both the choice of number of weights as well as the height at which the weight is first lifted.
Claims36
A device to allow a person to exercise comprising:
- (a) a single resisting force means to provide an adjustable amount of continuous force resistance to be lifted from a single point attachment, the force being present during lift and during return,
- (b) exercise grasping means comprising a horizontal bar to allow the person to grasp the bar and move the bar against the force,
- (c) cable means comprising two separate cables connecting two separate connection points on the grasping means to the single resisting force means wherein the movement of either connection point lifts against the single resisting force means,
- (d) a cable directioning means to train the cable means to training point locations positioned in a single plane on both sides of the person enabling the person to move the attachment points on the bar simultaneously against the resisting force means,
- (e) frame means comprising two vertical frame members the frame members being to support the cable directioning means and the cable means and to resist without distortion the applied forces from the person moving the bar against the single resisting force means,
- (f) two carriage means, one each freely riding up and down on opposite vertical frame members, and
- (g) releasable locking means to detachably attach ends of the bar to the two carriage means,
- wherein the carriage means are isolated from any forces from the single resisting force and any vertical force.
An exercise device comprising:
- (a) a support platform to hold and support a person doing exercises, to direct forces downwardly from the person or the auxiliary equipment,
- (b) a frame comprising two vertical frame members, each having an upper end and a lower end, a lower support member structurally and rigidly connecting the vertical frame members proximate to the lower end, and an upper support member structurally and rigidly connecting the vertical frame members proximate to the upper end,
- (c) weight distributing means to distribute counter vailing downward force from any exercise being conducted by a person from the support platform to the lower support member,
- (d) an exercise bar to allow the person using the device to grasp at least one grasping point and move the bar against a weight resistance, wherein the bar has two separated connection points,
- (e) an adjustable positioning means detachably secured to the vertical frame members to allow the bar to be detachably secured and supported at any chosen height to be trained to only vertical movement,
- (f) a single weight means to allow an adjustable amount of weight to be lifted from a single point location outside the area enclosed by the vertical frame members,
- (g) a pulley attached proximate to each inside of the frame, wherein the grasping point and the pulleys at the lower two corners are in a single plane,
- (h) cable means comprising two separate cables connecting the two connection points trained to the pulleys and finally to the point location on the weight means, wherein movement of either connection point lifts the single weight means,
- (i) two carriage means, one each freely riding up and down on opposite vertical frame members, and
- (j) releasable locking means to detachably attach ends of the bar to the two carriage means,
- wherein the carriage means are isolated from any forces from the single weight means and any vertical force, and
- (k) an adjustable selector means to allow adjusting the length of the cables to coincide with a chosen height in the adjustable racking means in which the bar is set where all the weights are down and exerting no load against the bar.
