Weight plate lifting exercise apparatus
First Claim
1. Weight lifting exercise apparatus and a stack of weight to be lifted including at least first and second weights laying face-to-face one above the other, said weight lifting exercise apparatus comprising:
- a frame;
at least one guide bar having a first end pivotally coupled to said frame and an opposite end pivotally coupled to said first weight;
an attachment by which said first weight is connected to said second weight from said stack of weights; and
lifting force generating means communicating with said first weight such that a pulling force applied to said lifting force generating means is transferred to said first weight to simultaneously cause said first weight and said second weight connected to said first weight to be lifted together in a linear path and said guide bar to rotate at said opposite end thereof relative to said frame through a circular path.

Abstract
A weight plate lifting exercise apparatus to enable any number of weight plates to be lifted off a stack of weight plates during an exercise. The weight plates are stacked in face-to-face alignment one above the other. A weight plate connector is affixed to the first weight plate atop the stack. The apparatus includes a frame and a pair of guide bars that are pivotally connected between a side of the frame and the weight plate connector. A cable communicates with the first weight plate atop the stack by way of the weight plate connector. A pulling force applied to the cable causes the first weight plate and any other weight plates that are detachably interconnected to the first weight plate to be displaced in a linear (i.e., vertical) lifting path. At the same time, the pair of guide bars will rotate relative to the frame through a circular path. The guide bars will at all times remain in spaced, parallel alignment with one another throughout their rotation to ensure that the weight plates are lifted smoothly and continuously from the stack.

14. The combination, comprising:
-
weight lifting exercise apparatus; and a stack of weights to be lifted by said weight lifting exercise apparatus, said stack including at least first and second weights adapted to be detachably connected in face-to-face alignment one above the other, said weight lifting exercise apparatus including; a frame; first and second guide bars pivotally coupled at respective first ends thereof to said frame and pivotally coupled at respective opposite ends to said first weight; and means for generating a lifting force communicating with said first weight such that a pulling force applied to said lifting force generating means is transferred to said first weight to simultaneously cause said first weight and said second weight detachably connected to said first weight to be lifted together in a linear path and said first and second guide bars to rotate at the respective opposite ends thereof relative to said frame through respective circular paths, said first and second guide bars at all times being positioned in spaced parallel alignment with one another when said guide bars rotate relative to said frame in response to the pulling force applied to said lifting force generating means.
