Abstract
A machine for exercising muscles of the human body which includes a movement arm pivotable about a horizontal axis by the user against a resistance provided by a weight stack. A drive shaft is connected to the movement arm and extends vertically downwardly below the weight stack where it is connected to a lever which in turn is connected to the lower end of a pin included in the weight stack. When the movement arm is rotated and pivoted in one direction it will move the drive shaft and the lever to raise the pin in the weight stack. The weight stack includes upper and lower stacks of weights independently connectable to the stack pin.
Claims12
A machine for exercising the human body comprising in combination, a movement arm having a generally horizontal axis about which the movement arm moves upon exercising muscles of the body, a weight stack having a plurality of stacked weights connectable to said movement arm to oppose movement of said movement arm about said axis in one direction, said weight stack having a generally vertical pin movable in a generally vertical direction relative to said weights while being connectable to one of said weights, a lever located below the weight stack and pivotally connected to the pin and to the movement arm to raise the pin to lift the weight when the movement arm is rotated in said one direction, a generally vertical drive shaft connected to and between the lever and movement arm to transmit movement therebetween and a link pivotally connected to the lever on a side of the drive shaft opposite the pin of the weight stack, said link being pivotally connected to said lever at an elevation below said weights, said link being pivotally connected to a stationary frame to pivotally mount the lever to the frame.
A machine for exercising the human body comprising in combination, a movement arm having an axis of movement about which the movement arm moves upon exercising muscles of the body, at least one weight connectable to said movement arm to oppose movement of said movement arm about said axis in one direction, a drive transmission between said movement arm and the weight including a lever connected to the weight to raise the weight when the movement arm is rotated in one direction about said axis, connecting means between said movement arm and the lever to transmit motion of said movement arm to the lever, a link pivotally connected to said lever and pivotally connected to a stationary support to mount the lever to said support, and wherein said movement arm is located above said lever and wherein said weight is included in a weight stack having a generally vertical pin movable relative to said weight, said weight being connectable to said pin to move with the pin, and wherein said lever is pivotally connected to the pin below the weight.
A machine for exercising the human body comprising in combination, a movement arm to be moved about an axis upon exercising muscles of the body, a weight connectable to the movement arm to oppose movement of the movement arm about said axis in one direction, and drive transmission means between said weight and said movement arm including a lever located below and pivotally connected to the weight to lift the weight when the movement arm moves in said one direction, and a link pivotally connected to said lever and pivotally mounted to a fixed support to allow the lever to undergo translatory movement relative to the fixed support.
