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.

First claim

What is claimed is:

1. 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, wherein the at least one biasing member provides a resistance force 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 connected to the frame, 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 non-damaging stop, and wherein the bias device is comprised of a spring or a fluid displacement device.

2. The exercise machine of claim 1 , wherein the bias device is comprised of the spring.

3. The exercise machine of claim 1 , wherein the bias device is comprised of the spring, wherein the shaft is movably connected to the spring in a linear manner, and wherein the spring is adapted to longitudinally receive a linear movement of the shaft.

4. The exercise machine of claim 1 , wherein the bias device is comprised of a fluid displacement cylinder.

5. The exercise machine of claim 1 , wherein the shaft has a longitudinal axis of movement that is parallel with respect to a longitudinal axis of the at least one rail.

6. The exercise machine of claim 1 , including a plunger attached to a distal end of the shaft, wherein the plunger is adapted to engage the movable platform.

7. The exercise machine of claim 6 , wherein a width of the plunger is greater than the width of the shaft.

8. The exercise machine of claim 1 , wherein the travel limit decelerator is adapted to engage a structural component of the movable platform.

9. The exercise machine of claim 8 , wherein the structural component of the movable platform comprises a trolley assembly.

10. The exercise machine of claim 1 , wherein the travel limit decelerator is connected to the at least one rail.

11. The exercise machine of claim 1 , wherein the at least one rail is comprised of a first rail and a second rail.

12. The exercise machine of claim 1 , including a mount connected to the frame, wherein the travel limit decelerator is connected to the mount.

13. The exercise machine of claim 12 , wherein the travel limit decelerator is adjustably positioned with the mount to change a longitudinal position of the shaft with respect to the at least one rail.

14. The exercise machine of claim 13 , wherein adjustment of the longitudinal position of the travel limit decelerator within the mount correspondingly adjusts a limit of travel for the movable platform.

15. The exercise machine of claim 13 , wherein adjustment of the longitudinal position of the travel limit decelerator within the mount correspondingly adjusts an engagement position of the shaft and the movable platform.

16. The exercise machine of claim 13 , including an adjustment mechanism adapted for adjusting the longitudinal position of the travel limit decelerator with respect to the at least one rail.

17. The exercise machine of claim 16 , wherein the adjustment mechanism is comprised of a nut and wherein the travel limit decelerator passes through the nut longitudinally, wherein when the nut is loosed the travel limit decelerator is configured to be slid longitudinally with respect to the mount to adjust the longitudinal position of the travel limit decelerator and wherein when the nut is tightened the travel limit decelerator is locked in a stationary position.

18. The exercise machine of claim 12 , wherein the mount is connected to the at least one rail.

19. 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, wherein the at least one biasing member provides a resistance force to the movable platform;
a stationary end platform connected to the frame and positioned near the first end of the frame; and
a travel limit decelerator connected to the frame, 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 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 adapted to engage the movable platform as the movable platform approaches the 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 stationary end platform so that the movable platform is brought to the smooth, gentle, non-damaging stop.

20. 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, wherein the at least one biasing member provides a resistance force 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 connected to the frame, 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;
