Abstract

An adjustable exercise machine for performing resistance exercises comprises a base and an upper frame including front and back end stationary exercise platforms, and a movable exercise platform that reciprocates between the stationary platforms. A plurality of biasing members is selectable by an exerciser via selector knobs to generate a bias force against the movable platform. A plurality of pivotable lift supports are connected between the base and the upper frame. Front and back actuators are connected between the base and the lift supports by lifting yokes to selectively raise and lower the front and back ends of the machine. The movable platform may be connected to move along the exercise machine by trolley wheel assemblies. A plurality of travel limit decelerators mounted on the rails engage and rapidly decelerates the movable platform as it reaches its limits of travel on the rails.

Claims20

Dependent claims

An exercise machine, comprising:

a frame having at least one rail;
a movable platform moveably connected to the at least one rail and adapted to be moveable along at least a portion of the at least one rail;
at least one biasing member adapted to be removably connected to the movable platform;
a stationary end platform connected to the frame and positioned near a first end of the frame;
and
a travel limit decelerator, the travel limit decelerator is adapted to engage the movable platform as the movable platform approaches the stationary end platform, wherein the travel limit decelerator is adapted to smoothly and gently decelerate the movable platform when the movable platform approaches the stationary end platform so that the movable platform is brought to a smooth, gentle, non-damaging stop;
wherein the travel limit decelerator comprises a shaft and a bias device connected to the shaft, wherein the bias device is adapted to provide a bias force to the shaft to smoothly and gently decelerate the movable platform to the smooth, gentle, non-damaging stop, and wherein the bias device is comprised of a spring or a fluid displacement device.

4 more elements

An exercise machine, comprising:

a frame having at least one rail, a first end and a second end opposite the first end, wherein the frame includes a central longitudinal axis and wherein the at least one rail has a longitudinal axis;
a movable platform moveably connected to the at least one rail and adapted to be moveable along at least a portion of the at least one rail;
at least one biasing member adapted to be connected to the movable platform;
a first stationary end platform connected to the frame and positioned near the first end of the frame;
a second stationary end platform connected to the frame and positioned near the second end of the frame;
and
a travel limit decelerator, the travel limit decelerator is adapted to engage the movable platform as the movable platform approaches the first stationary end platform, wherein the travel limit decelerator is adapted to smoothly and gently decelerate the movable platform when the movable platform approaches the first stationary end platform so that the movable platform is brought to a smooth, gentle, non-damaging stop;
wherein the travel limit decelerator has a longitudinal axis of movement that is parallel with respect to the longitudinal axis of the at least one rail;
wherein the travel limit decelerator is adapted to engage a structural component of the movable platform;
wherein the travel limit decelerator comprises a shaft movably connected to the frame in a linear manner and a spring connected to the shaft, wherein the shaft has a longitudinal axis of movement that is parallel with respect to the longitudinal axis of the at least one rail, wherein the shaft is adjustably positioned with the frame to change a longitudinal position of the shaft with respect to the frame, and wherein adjustment of the longitudinal position of the travel limit decelerator correspondingly adjusts a limit of travel for the movable platform;
wherein the shaft is adapted to engage the movable platform as the movable platform approaches the first stationary end platform, wherein the spring is adapted to provide a bias force to the shaft to smoothly and gently decelerate the movable platform when the movable platform approaches the first stationary end platform so that the movable platform is brought to the smooth, gentle, non-damaging stop.
