1. An exercise device comprising:
- a frame;
a reaction bar engageable by an exercising person for sequential movement with respect to the frame by the exercising person in a first direction and in a second direction opposite to the first direction;
means mounting the reaction bar on the frame for movement relative to the frame whereby said reaction bar has a first limit of travel in the first direction and a second limit of travel in the second direction;
fluid operated means connected between the frame and the reaction bar for exertion of fluid force on the reaction bar in a direction tending to move the reaction bar in the second of said directions;
first means associated with the fluid operated means to change the fluid force exerted by the fluid operated means, and second means associated with the reaction bar engageable with the first means when the reaction bar reaches the second limit of travel to provide a first force value, and when the reaction bar reaches the first limit of travel to provide a second force value, whereby the exercising person exerts manual force on the reaction bar opposed to the force exerted upon the reaction bar by the fluid operated means to overcome the fluid force to move the reaction bar in the first direction and then resists the fluid force while permitting movement of the reaction bar in the second direction.

Abstract
An exercise device of the weight lifting type wherein the force or load conventionally supplied by weights is effectively simulated by fluid means such as a hydraulic assembly. One or more hydraulic assemblies act upon a reaction bar to tend to move it one direction. The exercising person engages the reaction bar and exerts force upon it in the direction opposite to the force exerted by the hydraulic assemblies. Force is exerted in a direction opposite to the direction of the force exerted by the hydraulic assembly in both in an extension and retraction phase of the exerciser'"'"'s routine.

24. An exercise device comprising:
- a frame;
a reaction bar engageable by an exercising person for sequential movement with respect to the frame by the exercising person in a first direction and in a second direction opposite the first direction;
said reaction bar including first and second parallel force arms each pivotally connected at one end to the frame and having outer ends pivotally movable in said first and second directions with respect to the frame;
said outer ends having handles adapted to be grasped by an exercising person;
said first and second force arms being mounted on the frame for pivotal movement about a common axis, a first crank arm extended from the first force arm opposite the point of connection of the first force arm to the frame, a second crank arm connected to the second force arm opposite the point of connection of the second force arm to the frame, fluid operated means connected to the frame and the reaction bar for exertion of fluid force on the reaction bar in a direction tending to move the reaction bar in the second of said directions, whereby the exercising person exerts manual force on the reaction bar opposed to the force exerted upon the reaction bar by the fluid operated means to overcome the fluid force to move the reaction bar in the first direction and then resist the force permitting movement of the reaction bar in the second direction;
said fluid operated means including a first linear hydraulic actuator having first and second ends movable relative to one another with one end connected to the frame and the other connected to the reaction bar, and a second linear actuator having first and second ends movable relative to one another with one end connected to the frame and the other end connected to the reaction bar, and means connecting said first and second linear hydraulic actuators to the first and second crank arms;
said first and second force arms have a first limit of travel in the first direction and a second limit of travel in the second direction, said fluid operated means operable to selectively apply hydraulic force of a first value and a second value to the first and second hydraulic actuators, switch means connected to the fluid operated means for switching between the first force value and the second force value, and means connected to one of the force arms for engagement of the switch means at the first limit of travel to switch from the first force value to the second force value, and for engagement of the switch means at the second limit of travel to switch from the second force value to the first value. - View Dependent Claims (25, 26, 27)
