Muscular exercise equipment

Abstract

The present invention relates to muscular exercise equipment. In particular, disclosed is a muscular exercise apparatus comprising: an upper support bar, which has a certain length and on both sides of which connecting rods are disposed; a lower support bar, which has a certain length and on both sides of which connecting rods are disposed, wherein the connecting rods of the upper support bar and the connecting rods of the lower support bar are fastened to each other such that the upper support bar and the lower support bar have a certain angle therebetween; and a central support bar for supporting the bending motion of at least one of the upper support bar and the lower support bar.

What is claimed is: 
     
         1 . Muscular exercise equipment comprising:
 a first module comprising an upper support bar, and upper connecting rods connected at both ends of the upper support bar;   a second module comprising a lower support bar, and lower connecting rods connected at both ends of the lower support bar; and   a central support bar coupled to ends of the upper and lower connecting rods,   wherein stepped portions are formed so that the ends of the upper connecting rods and the lower connecting rods are coupled so as to face each other, and the central support bar is disposed at an area in which the stepped portions are coupled, and   a tension ring configured to provide an elastic force in an opposite direction to a rotating motion of at least one of the first and second modules using the central support bar as an axis is inserted in and disposed at the stepped portion of the upper connecting rods.   
     
     
         2 . The muscular exercise equipment of  claim 1 , wherein a pin hole configured to pass through toward the central support bar, and a coupling pin inserted into and passing through the pin hole and coupled to a center of the tension ring disposed at the stepped portion of the upper connecting rods are disposed at the stepped portion of the lower connecting rods. 
     
     
         3 . The muscular exercise equipment of  claim 2 , wherein a pin cover configured to cover an opening portion of the pin hole is further disposed at the stepped portion of the lower connecting rods. 
     
     
         4 . The muscular exercise equipment of  claim 2 , wherein a bearing having a center through which the coupling pin passes and configured to support a rotation of the upper connecting rod, and an insertion hole configured to support an insertion of the tension ring are disposed at the stepped portion of the upper connecting rods. 
     
     
         5 . The muscular exercise equipment of  claim 4 , wherein the tension ring comprises at least one rail groove formed at an outer portion thereof; and a ring screw thread formed at the outer portion to be fastened to a coupling nut disposed at the central supporting bar, and a pin insertion hole in which the coupling pin is inserted and coupled. 
     
     
         6 . The muscular exercise equipment of  claim 5 , further comprising a rail protrusion formed at one side of an inner wall of the insertion hole formed at the upper connecting rod, and coupled to the rail groove.
