<p><P>PROBLEM TO BE SOLVED: To provide a muscle strength enhancer whose structure can be simplified by converting force applied to arms of the muscle strength enhancer to force for deforming a spring installed on the head in the vertical direction. <P>SOLUTION: The arm enhancer includes: a head having arm connection parts formed at both sides of the spring setting part; a pair of arms extending with the upper ends freely rotatably joined to the arm connection parts on both sides of the head; a spring member which is vertically installed at the spring setting part of the head, and provides a resilient force generated while compressing or extending vertically by transmitting such a movement that the pair of arms approach each other, to the arms; a pair of links having first ends connected to each arm and second ends extending between the arms; and a spring operation part which has a link connection part connected to the second ends of the links, and is constituted so that the movement when the arms approach each other is transmitted to the link connection part through the links and the spring member is compressed or extended by using added power. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
