Portable exercising device

Abstract

The present invention is directed to a portable exercising device for arms. The portable exercising device comprising an elongated first frame, the first frame having a proximal end and a distal end; an elongated second frame, the second frame having a proximal end and a distal end, the proximal end of the first frame pivotally coupled to the proximal end of the second frame; a first armband coupled to the first frame, the first armband configured to be worn in an arm; a second armband coupled to the second frame, the second armband configured to be worn in a forearm; a resistance member extending from the first frame to the second frame, the resisting member configured to resist the pivotal motion of the first frame towards the second frame. The resistance produced by the resistance member is transferred to the muscles, thus exercising the arm.

What is claimed is: 
     
         1 . A portable exercising device comprising:
 an elongated first frame, the first frame having a proximal end and a distal end;   an elongated second frame, the second frame having a proximal end and a distal end, the proximal end of the first frame pivotally coupled to the proximal end of the second frame;   a first armband coupled to the first frame, the first armband configured to be worn over an arm;   a second armband coupled to the second frame, the second armband configured to be worn over a forearm;   a resistance member extending from the first frame to the second frame, the resisting member configured to resist the pivotal motion of the first frame relative to the second frame.   
     
     
         2 . The portable exercising device of  claim 1 , wherein the portable exercising device further comprises a bar, the bar shaped to be grasped with a hand, the bar disposed on the distal end of the second frame. 
     
     
         3 . The portable exercising device of  claim 2 , wherein the bar is slidably coupled to the second frame. 
     
     
         4 . The portable exercising device of  claim 3 , wherein the second frame comprise a slot and the bar is slidably mounted in the slot. 
     
     
         5 . The portable exercising device of  claim 1 , wherein the resistance member comprises:
 a sealed cylindrical body having a fluid therein; and   a plunger sealably received in the sealed cylindrical body, the plunger configured to reciprocate within the sealed cylindrical body.   
     
     
         6 . The portable exercising device of  claim 5 , wherein the fluid is air. 
     
     
         7 . The portable exercising device of  claim 5 , wherein the sealed cylindrical body is rotatably coupled to the first frame and the plunger is rotatably coupled to the second frame. 
     
     
         8 . The portable exercising device of  claim 5 , wherein the sealed cylindrical body is rotatably coupled to the second frame and the plunger is rotatably coupled to the first frame. 
     
     
         9 . The portable exercising device of  claim 5 , wherein the resistance member further comprises a resistance adjustment member, the resistance adjustment member is sealably coupled to the sealed cylindrical body. 
     
     
         10 . The portable exercising device of  claim 5 , wherein the resistance member is an air release valve. 
     
     
         11 . The portable exercising device of  claim 1 , wherein the first armband and the second armband comprises a strap and a fastener. 
     
     
         12 . The portable exercising device of  claim 11 , wherein the strap is made of nylon. 
     
     
         13 . The portable exercising device of  claim 11 , wherein the fastener is a hook and loop fastener. 
     
     
         14 . The portable exercising device of  claim 11 , wherein the first armband and the second armband are coupled to the first frame and the second frame perpendicularly to the direction of moving of the first frame relative to the second frame.
