ABSTRACT:
FIELD OF INVENTION
The present invention generally relates to leg press exercise machines of the type including a movement arm in the form of a foot member engageable and movable by the feet of an exerciser against the opposition of a resistance typically one or more weights attached or connected to or mounted on the movement arm.
OBJECTS OF THE PRESENT INVENTION
An object of the present invention is to provide a novel and improved leg press machine of the type described above.
Another object of the present invention is to provide in such a leg press machine a linkage mechanism which mounts the movement arm to the stationary frame such that the work force required to initially move the movement arm increases as the movement arm is extended from a starting position adjacent the exerciser and an extended position displaced away from the exerciser.
A further object of the present invention is to provide a novel and improved leg press machine which facilitates entry to and exit from the machine.
Another object of the present invention is to provide a novel and improved leg press machine which facilitates the handling of free weights from a storage area on a frame of the machine to a resistance arm which is connected to the movement arm to oppose movement of the movement arm in one direction.
SUMMARY OF PREFERRED EMBODIMENT OF THE PRESENT INVENTION
One preferred embodiment of the present invention includes a movement arm mounted to a fixed frame by a pair of links pivotally connected to the movement arm and pivotally connected to the frame for allowing movement of the movement arm including a foot board between a first or start position adjacent the exerciser and an extended position displaced away from the exerciser. Movement of the movement arm towards the extended position is opposed by a resistance including a resistance weight arm pivotally mounted to the frame while also being connected to one of said pairs of links by another link. One or more free weights are mounted to the resistance weight arm. The frame includes a storage rack for storing resistance weights at a convenient level in the waist-chest area of the exerciser to facilitate the handling of the weights between the storage rack and the resistance weight arm. In order to facilitate entrance to and exit from the machine, a prop is mounted to the stationary frame for movement between an idle position where it is spaced from the weight arm and an active position wherein it engages the weight arm and holds it in a raised position allowing entrance to or exit from the machine by the exerciser. The prop arm is moved between its positions by a handle conveniently within the reach of the exerciser.
