1. An exercising device comprising:
- lifting means supported to allow an exerciser to engage a portion thereof to carry out one or more selected exercises, said lifting mechanism adapted for movement in at least two opposing directions;
load regulating means being coupled to said lifting means and selectively operable to vary a resistance applied against the movement of said lifting means as said lifting means is being moved in either or both of said directions;
control means adapted to selectively operate said load regulating means to control said amount of resistance applied agains the movement of said lifting means, said control means defining a range of motion and a force curve for each of said exercises, which force curve delineates said amount of varied resistance to be applied against said movement of said lifting means independent of any force being exerted by or against said lifting means and for incremental degrees in movement of said lifting means, said control means operating said load regulating means in relation to said incremental movement of said lifting means to effect the application of said applied resistance by said load regulating means as said lifting means is being moved during each of said exercises in a positive resistance direction for said selected exercise, said control means further selectively operating said load regulating means to reduce said applied resistance to substantially zero when said lifting means is moved in a negative resistance direction for one of said exercises, provided that said direction is not a positive resistance direction for another of said exercises; and
display means electrically coupled to said control means which includes one or more portions for visually displaying various conditions to said exerciser during said selected exercise, and which includes one or more input portions to allow said exerciser to operate said device, with one of said input portions being adapted to receive an indicated maximum resistance from said exerciser, which maximum resistance is correlated by said control means to a position on said force curve which delineates a maximum amount of said resistance to be applied to said lifting means.

Abstract
A resistance mechanism for exercise devices which progressively varies resistance applied to a lifting mechanism in only positive resistance directions, while reducing the resistance to substantially zero if the lifting mechanism is moved in a negative resistance direction.

15. An exercising device comprising:
-
lifting means supported to allow an exerciser to engage a portion thereof to carry out a selected exercise, said lifting mechanism adapted for movement in at least two opposing directions; brake means which includes one or more rotatably shafts, said brake means being selectively operable to apply a resistance to the rotation of one of said shafts, with said shaft being further coupled to the remainder of said shafts to transfer said applied resistance, one of said brake means shafts being coupled to said lifting means to transfer said applied resistance to said lifting means as said lifting mean sis being moved during said exercise; sensing means coupled to one of said rotatably shafts of said brake means which is adapted to sense in incremental degrees said rotational position of said shaft, and which sensing means generates a signal indicative of said sensed rotational position of said shaft; control means electrically coupled to said sensing means and said brake means, said control means selectively operating said brake means to control said amount of resistance applied against the movement of said lifting means, said control means defines a range of motion and a force curve for each of said exercises, which force curve delineates said amount of varied resistance to be applied against said movement of said lifting means independent of any force being exerted by or against said lifting means, and for incremental degrees in movement of said lifting means, said control means operating said brake means in relation to said incremental movement of said lifting means to effect the application of said applied resistance by said brake means in accordance with said force curve as said lifting means is being moved during each of said exercises in a positive resistance direction for said selected exercise, said control means further selectively operating said brake means to reduce said applied resistance to substantially zero when said lifting means is moved in a negative resistance direction for one of said exercises, provided that said direction is not a positive resistance direction for another of said exercises and further operating said brake means when said exerciser fails to continue to move said lifting means in said positive resistance direction within a prescribed period of time; and display means electrically coupled to said control means which includes at least a first portion for visually displaying an indication of a degree said exerciser has moved said lifting means through said range of motion in said positive resistance direction to said exerciser during said movement of said lifting means, a second portion for indicating a rating of said exerciser'"'"'s performance of said exercise as based upon an average of that extent said exerciser moved said lifting means through said range of motion and that number of times said exerciser repeated said movement of said lifting means through said range of motion within a given period of time, and a third portion which is adapted to receive an indicated maximum resistance from said exerciser, which maximum resistance is correlated by said control means to a position on said force curve which delineates a maximum amount of said resistance to be applied to said lifting means. - View Dependent Claims (16)
