Exercise Device And Exercise System

Abstract

The invention relates to an exercise device, comprising a frame, a resistance system; and an engagement element, the engagement element being connected to the resistance system using a first line end and a second line end, wherein the resistance system is configured to provide the resistance to extension of the first line end independently from the resistance to extension of the second line end. The invention also relates to an exercise system comprising two exercise devices according to any one or more of the preceding claims.

1 . An exercise device, comprising:
 a frame;   a resistance system; and   an engagement element,   the engagement element being connected to the resistance system using a first line end and a second line end, the resistance system providing a resistance to extension of the first line end and the second line end,   the first line end engaging the frame at a first engagement mechanism and the second line end engaging the frame at a second engagement mechanism, which is in a different position than the first engagement mechanism, so that a movement of the engagement element with respect to the frame in a first direction from the second engagement mechanism to the first engagement mechanism corresponds to an extension of at least the second line end, and a movement of the engagement element with respect to the frame in a second direction from the first engagement mechanism to the second engagement mechanism corresponds to an extension of at least the first line end, the exercise device thereby allowing reciprocal movement of the engagement element with respect to the frame against the resistance provided by the resistance system,   wherein the resistance system is configured to provide the resistance to extension of the first line end independently from the resistance to extension of the second line end.   
     
     
         2 . The exercise device according to  claim 1 , wherein the resistance system comprises at least two separate resistance mechanisms, each independently connected to the first line end and the second line end respectively. 
     
     
         3 . The exercise device according to  claim 1 , the resistance system comprising at least one flywheel for providing the resistance, possibly further comprising a magnetic brake for braking the flywheel. 
     
     
         4 . The exercise device according to  claim 1 , further comprising at least one retraction mechanism configured for retracting the first line end and/or the second line end. 
     
     
         5 . The exercise device according to  claim 1 , comprising a first line having the first line end and at least one second line having the second line end. 
     
     
         6 . The exercise device according  claim 1 , the frame comprising at least one leg and a first beam supported by the at least one leg, the first beam carrying at least one of the first and second engagement mechanisms. 
     
     
         7 . The exercise device according to  claim 6 , further comprising a second beam supported by the at least one leg, the second beam carrying the other of the first and second engagement mechanisms. 
     
     
         8 . The exercise device according to  claim 6 , the resistance system being at least partly supported by the first and/or second beam. 
     
     
         9 . The exercise device according to  claim 2 , wherein the first and the second beam each carry one of the first and second resistance mechanisms. 
     
     
         10 . The exercise device according  claim 6 , the first beam and/or the second beam being moveable with respect to the leg. 
     
     
         11 . The exercise device according to  claim 10  wherein the first beam and/or the second beam being moveable along a longitudinal direction of the leg. 
     
     
         12 . The exercise device according to  claim 10 , the first beam and/or the second beam being rotatable about an axis that is substantially perpendicular to a or the longitudinal direction of the leg and substantially perpendicular to a longitudinal direction of the respective beam. 
     
     
         13 . The exercise device according to  claim 10 , the first beam and/or the second beam being pivotable about an axis that is parallel to a or the longitudinal direction of the leg. 
     
     
         14 . The exercise device according to  claim 1 , further comprising a sensor configured for sensing an amount of work performed by moving the engagement element. 
     
     
         15 . The exercise device according to  claim 14  further comprising a display configured to display the amount of work. 
     
     
         16 . The exercise system, comprising two exercise devices according to  claim 1 . 
     
     
         17 . The exercise system according to  claim 16  wherein the two exercise devices being attached to each other via their frames. 
     
     
         18 . The exercise system according to  claim 16 , wherein a distance between corresponding engagement mechanisms of the two exercise devices is adjustable.
