Exercise device

Abstract

An exercise device includes a cylindrical housing closed at one end and having a spring arranged therein. A plunger is connected with the housing and abuts against the spring. The plunger is adapted to reciprocate within the housing against the force of the spring. More particularly, the plunger includes a handle exterior of the housing which is grasped by the user. The closed end of the housing includes a pad which is placed against the chest of the user. The user grips the handle and displaces the plunger against the force of the spring to exercise the biceps muscle.

1 . An exercise device, comprising
 (a) a housing having a longitudinal axis and containing a chamber, a first end of said housing being closed and a second end of said housing containing an opening communicating with said chamber;   (b) a spring arranged in said chamber; and   (c) a plunger connected with said housing second end for reciprocal movement within said chamber against said spring, whereby when said housing first end is arranged against the chest area of the user, the user grips said plunger and pulls it toward the chest against the spring to exercise the user's biceps muscle.   
   
   
       2 . An exercise device as defined in  claim 1 , wherein said plunger comprises an elongated rod coaxial with the longitudinal axis of said housing, said rod having a washer secured adjacent to one end, said washer abutting against an end of said spring. 
   
   
       3 . An exercise device as defined in  claim 2 , wherein said rod further includes a handle connected with another end thereof. 
   
   
       4 . An exercise device as defined in  claim 3 , wherein said housing has a cylindrical configuration. 
   
   
       5 . An exercise device as defined in  claim 4 , wherein said plunger is removably connected with said housing. 
   
   
       6 . An exercise device as defined in  claim 5 , wherein said plunger includes an internally threaded cap adapted for connection with external threads on said housing second end, said cap having a central opening for receiving said rod. 
   
   
       7 . An exercise device as defined in  claim 4 , and further comprising a pad connected with said housing first end for abutting against the chest of the user. 
   
   
       8 . An exercise device as defined in  claim 7 , wherein said pad closes said housing first end and acts as a stop for said spring.
