Handheld exercise device

Abstract

A handheld exercise device having two pairs of opposing handles that are coupled by resilient members that provide tension to moving one pair of handles away from each other and to moving the other pair of handles towards each other. One pair of the handles are hingedly attached to the resilient members and the other pair are fixedly attached. The exercise device is portable and can be disassembled by detaching at least one pair of the handles from the resilient members.

1 . A handheld exercise device comprising:
 a pair of resilient members each having a handle portion located between two end portions;   a pair of opposing end-grips, each of the opposing end-grips hingedly coupled to each of the pair of resilient members at opposing sides of the opposing end-grip, wherein the pair of resilient members provide tension to moving handle portions of the pair of resilient members away from each other and the pair of resilient members provide tension to moving end-grips towards each other.   
     
     
         2 . The handheld exercise device of  claim 1 , wherein each of the pair of resilient members comprise a side-grip and two resilient limbs fixedly coupled to opposing ends of the side-grip. 
     
     
         3 . The handheld exercise device of  claim 2 , wherein side-grip and two resilient limbs are releasably coupled by a clamp down binding. 
     
     
         4 . The handheld exercise device of  claim 2 , wherein the end-grips hingedly coupled to the resilient members are releasably coupled. 
     
     
         5 . The handheld exercise device of  claim 3 , wherein the end-grips hingedly coupled to the resilient members are releasably coupled by a clevis pin. 
     
     
         6 . The handheld exercise device of  claim 3 , wherein the end-grips hingedly coupled to the resilient members are releasably coupled by a Nordic ski-type binding having a bar and moveable jaw. 
     
     
         7 . The handheld exercise device of  claim 1 , wherein at least one of the end-grips and the handle portion of the pair of resilient members have a plurality of handle positions. 
     
     
         8 . The handheld exercise device of  claim 2 , wherein the side-grip is rotatable about an axis of the side-grip. 
     
     
         9 . The handheld exercise device of  claim 2 , wherein the side-grip is curved any one of inwards or outwards. 
     
     
         10 . The handheld exercise device of  claim 1  further comprising a plurality of camera-detectable markers to facilitate motion capture of the device. 
     
     
         11 . The handheld exercise device of  claim 1  wherein a sensor is coupled to least one of the resilient members to measure a bend amount of the at least one resilient member. 
     
     
         12 . The handheld exercise device of  claim 2 , wherein the resilient limbs are configured to attach resilient sub-members to increase tension of the resilient limbs. 
     
     
         13 . The handheld exercise device of  claim 2 , wherein the resilient members have at least one attachment mechanism to attach a resilient band between the resilient members to increase tension. 
     
     
         14 . The handheld exercise device of  claim 1  wherein resilient members provide tension to moving handle portions of the pair of resilient members towards each other in a limited range of motion. 
     
     
         15 . A portable exercise device comprising:
 a first pair of opposing handles each having two opposed fixed attachment portions;   a second pair of opposing handles each having two opposed hinged attachment portions;   at least four resilient limbs, each of the resilient members having a fixed attachment portion for coupling with one of the two opposed fixed attachment portions of one of the first pair of opposing handles and a hinged attachment portion for hingedly coupling with one of the two opposed hinged attachment portions of one of the second pair of opposing handles, the fixed attachment portion and the hinged attachment portion located at opposing end portions of each of the resilient members.
