  • the crossbar 90 is hooked and fixed to the hooks 112 . Since the hooks 112 are installed along the longitudinal direction of the post 110 , the crossbar 90 may be installed on a hook 112 of a desired height. The crossbar 90 is installed horizontally on the post 110 by the hooks 112 . The muscle strength training apparatus 50 is fixed to the crossbar 90 through the fixing part described above.
  • the hooks 112 described above may be manufactured by punching a metal plate with a laser and then attached to the post 110 by welding or bolting. Thus, the hooks 112 is easily manufactured.
  • the fixing part described above may be composed of a sleeve 57 .
  • the sleeve 57 has an inner diameter greater than an outer diameter of the crossbar 90 .
  • the sleeve 57 is horizontally fitted over the crossbar 90 , and is rotatably integrally fixed to the crossbar 90 .
  • the above-described connection part illustrated in FIG. 8 may be vertically connected to a central portion of the sleeve 57 .
  • the connection part illustrated in FIG. 8 is preferably connected in communication with the sleeve 57 so as to reduce the overall weight.
  • the sleeve 57 may have a bearing 57 a installed on an inner circumferential surface thereof.
  • the bearing 57 a is configured as a circular ball bearing and the crossbar 90 passes through the center thereof.
  • the bearing 57 a reduces friction of the sleeve 57 against the crossbar 90 when the sleeve 57 is rotated about the crossbar 90 by the user.
  • the sleeve 57 is rotated smoothly.
  • the bearing 57 a is integrally fixed to the inner circumferential surface of the sleeve 57 by a bearing fitting.
  • the bearing fitting supports a side surface of the bearing 57 a to detachably fix the bearing 57 a to the inner circumferential surface of the sleeve 57 .
  • the bearing fitting may include a step 57 p protruding from the inner circumferential surface of the sleeve 57 to support a first side of the bearing 57 a, and a snap ring SR installed on the inner circumferential surface of the sleeve 57 to support a second side of the bearing 57 a.
  • the bearing fitting may be configured to include a pair of snap rings SR so that the opposite sides of the bearing 57 a are supported by the snap rings SR.
  • the snap rings SR may be fixed to the inner circumferential surface of the sleeve 57 so as to be positioned on the opposite sides of the bearing 57 a, thereby supporting the opposite sides of the bearing 57 a. Since the configuration of the snap rings SR can be easily understood by those skilled in the art, a detailed description thereof will be omitted.
  • the sleeve 57 may have a waterproof cover 57 b installed at each end thereof.
  • the waterproof cover 57 b is installed on the outside of the bearing 57 a to close the outside of the bearing 57 a.
  • the waterproof cover 57 b may be configured as, for example, a rubber plate or a rubber stopper.
  • the waterproof cover 57 b is detachably fixed to the sleeve 57 by a cover fitting.
  • the cover fitting may be composed of a snap ring SR installed on the inner circumferential surface of the sleeve 57 to support a surface of the waterproof cover 57 b along an outer periphery of the waterproof cover 57 b. Since the snap ring SR is the same configuration as the snap ring SR of the bearing fitting described above, a detailed description thereof will be omitted.
  • the lower cap CP described above may be provided with a spring seat SP.
  • the spring seat SP is formed to protrude from the lower cap CP to support an outer circumferential surface of the elastic body 62 described above.
  • the spring sheet SP supports the elastic body 62 in close contact with the outer circumferential surface of the elastic body 62 .
  • the elastic body 62 is prevented from moving during expansion and contraction, and thus is prevented from colliding with the inner circumferential surface of the sleeve 57 , thereby preventing collision noise from being generated.
  • the muscle strength training apparatus 50 as described above is installed by fitting the sleeve 57 over the crossbar 90 installed horizontally in the post 110 of the hanger.
  • the user can exercise while holding the handle under the cylinder 63 vertically connected to the sleeve 57 .
  • the sleeve 57 is rotated smoothly by the bearing 57 a and is operated smoothly outdoors since it is waterproofed by the waterproof cover 57 b.
  • the elastic body 62 is supported by the spring seat SP, the elastic body 62 expands and contracts stably, and noise caused by the elastic body 62 is prevented.
  • each of the posts 110 described above is vertically installed on the ground as a bottom flange thereof is bolted with a bolt B to a base BS buried in the ground.
  • opposite ends of the crossbar 90 described above are fixed to the posts 110 by bolts B.
  • the crossbar 90 is provided with a snap ring SR caught by the bearing 57 a of the sleeve 57 .
  • the crossbar 90 is provided with a snap ring SR caught by the bearing 57 a of the sleeve 57 .
  • the snap ring SR is installed in a snap ring groove 90 a formed in the crossbar 90 , and is supported and caught by the bearing 57 a to prevent the sleeve 57 from moving.
  • the muscle strength training apparatus 50 does not move along the crossbar 90 during exercise.
  • the crossbar 90 or post 110 described above may be provided with a stopper.
  • the stopper prevents the sleeve 63 , the clamp 55 , or the hook 52 of the above-described fixing part rotatably installed on the crossbar 90 from rotating 360 degrees about the crossbar 90 .
  • the stopper prevents the muscle strength training apparatus 50 from being rotated by 360 degrees about the crossbar 90 .
  • the stopper prevents the muscle strength training apparatus 50 from being rotated 360 degrees and colliding with the user's occipital region.
  • the stopper may be composed of, for example, a bending stick 92 bent and protruding from the crossbar 90 , and controlling a rotation angle of the fixing part by catching the fixing part or the connection part through a protruding portion thereof.
  • the stopper may be composed of, for example, a barricade 95 configured as a panel, fixed to an upper portion of each of the posts 110 at a higher position than the crossbar 90 , and controlling the rotation angle of the fixing part by catching the fixing part or the connection part.
  • the bending stick 92 or the barricade 95 catches the sleeve 63 when the muscle strength training apparatus 50 is rotated.
  • the bending stick 92 or the barricade 95 controls a rotation angle of the muscle strength training apparatus 50 to prevent a safety accident from occurring.
  • the barricade 95 may be configured as a bar installed at an upper end of the post 110 together with the crossbar 90 .
  • the bar is installed at an upper end of the crossbar 90 to control the rotation angle of the muscle strength training apparatus 50 by catching the cylinder 63 . Since the configuration of the bar can be easily understood by those skilled in the art, a detailed description thereof will be omitted.
