Multifunction apparatus for execution of exercises of strengthening of muscle systems

Abstract

The present invention is a multifunction apparatus to carry out muscle system strengthening to be used in both inside gymnasium and in “home gym” environments. The invention is made of a main metallic frame with a parallelepiped shape and provided with a support base made of three parallel tubular elements. A quadrangular cross section is either welded together or connected by means of bolts perpendicular to two tube shaped parts, which have a quadrangular cross section. Two cylinder-shaped columns are connected by either welding or of bolts. The last one is made up by three tube shaped parallel parts, which each have a quadrangular cross section, either welded or bolted perpendicular to two tube shaped parts. The lower support base and higher platform provide strength and capacity to prevent the main frame from being deformed, and they allow a perfect verticality of cylindrical columns and quadrangular shaped columns.

       9 . A multifunction exercise apparatus for strengthening of muscles, the apparatus comprising:
 a completely metallic main frame having a parallelepiped shape, said main frame having a support base with feet extending downwardly therefrom, said main frame having four quadrangular columns supported by said support base in which a first two of said four quadrangular columns is at a front of said main frame and in which a second two of said four quadrangular columns is at back of said main frame, said main frame having a pair of cylindrical columns in which respective upper ends of said pair of cylindrical columns are connected by tubular members of quadrangular cross section;   a pair of movable frames each having a pair of tubular elements, said pair of movable frames having a rectangular shape, the pair of tubular elements being hollow and extending in a vertical orientation in parallel relation to each other, the pair of tubular elements respectively receiving said pair of cylindrical columns therein, said pair of movable frames having a first horizontal bar and a second horizontal bar extending in parallel relation between the pair of tubular elements, said first horizontal bar connected at an upper end of the pair of tubular elements, said second horizontal bar connected to a lower end of the pair of tubular elements, the pairs of tubular elements being vertically movable along said pair of cylindrical columns so as to cause a corresponding movement of the first and second horizontal bars; and   a pair of supports supporting barbells thereon, said pair of supports being hooked to said pair of movable frames.   
   
   
       10 . The apparatus of  claim 9 , said pair of cylindrical columns having a plurality of circular holes formed at a front thereof, said plurality of circular holes being equally spaced from each other, the apparatus further comprising:
 a plurality of pins received by at least some of said plurality of circular holes so as to fix said pair of movable frames at a desired height along said pair of said cylindrical columns.   
   
   
       11 . The apparatus of  claim 9 , further comprising:
 a pulley system affixed at a center of said main frame, said pulley system comprising a movable element with disks received thereon, said pulley system having a pair of vertical bars having said movable elements slidably mounted thereon, said pulley system having a traction bar connected thereto, said traction bar suitable for causing a lifting of said movable element.   
   
   
       12 . The apparatus of  claim 11 , said movable element comprising a pair of tube-shaped members receiving respectively said pair of vertical bars so as to be slidably movable along said pair of vertical bars. 
   
   
       13 . The apparatus of  claim 11 , said support base having a central element extending thereacross, said central element having a small frame extending upwardly therefrom, said small frame having a vertical bars extending upwardly therefrom so as to limit a downward movement of said movable element. 
   
   
       14 . The apparatus of  claim 9 , each of said second two of said four quadrangular columns having at least a pair of rods extending perpendicular thereto. 
   
   
       15 . The apparatus of  claim 9 , each of said first two of said four quadrangular columns having a pair of springs extending from a back thereof, said pair of springs suitable for supporting a vertical position of the barbells. 
   
   
       16 . The apparatus of  claim 9 , each of said pair of supports having a rectangular plate bent at 90° so as to define a horizontal bracket and a hammering element, said horizontal bracket having an end bent upwardly, a strengthening bar extends transversely between said horizontal bracket and said hammering element, each of said pair of supports having a hook at an end thereof.
