Muscle strength training apparatus

Abstract

Proposed is a muscle strength training apparatus including a fixing part detachably or integrally fixed to a horizontal crossbar, a connection part vertically connected to a lower portion of the fixing part, and a handle installed to a lower portion of the connection part to be held by a hand of a user, wherein the user can exercise while holding the handle.

1 . A muscle strength training apparatus comprising:
 a fixing part detachably or integrally fixed to a horizontal crossbar;   a connection part vertically connected to a lower portion of the fixing part; and   a handle installed to a lower portion of the connection part to be held by a hand of a user,   wherein the fixing part is rotatably fixed to the crossbar, and   wherein the the handle is suspended in air as the connection part is fixed to the crossbar through the fixing part.   
     
     
         2 . The muscle strength training apparatus of  claim 1 , wherein the fixing part is composed of any one of:
 a hook having a lower portion to which the connection part is vertically connected, bent in a “∩” shape so as to be hung on the crossbar, and detachably fixed to the crossbar;   a stick clamp having a lower portion to which the connection part is vertically connected, and integrally fixed to the crossbar in a shape surrounding the crossbar; and   a sleeve having a lower portion to which the connection part is vertically connected, and fitted over the crossbar and integrally fixed to the crossbar.   
     
     
         3 . The muscle strength training apparatus of  claim 2 , wherein the stick clamp comprises:
 a pair of bodies coupled to each other in a state of facing each other with respect to a hinge, forming a hollow inner circumferential surface for restraining the crossbar when coupled, and fixed to the crossbar while surrounding an outer circumferential surface of the crossbar; and   a protruding mounting portion protruding from a lower portion of the body so that the connection part is connected to the protruding mounting portion.   
     
     
         4 . The muscle strength training apparatus of  claim 2 , wherein the sleeve has an inner diameter greater than an outer diameter of the crossbar and is rotatably fixed to the crossbar, and
 the fixing part further comprises:   a bearing installed in the sleeve to reduce friction of the sleeve against the crossbar; and a bearing fitting supporting at least a side of the bearing to detachably fix the bearing to an inner circumferential surface of the sleeve,   wherein the bearing fitting comprises:   a step protruding from the inner circumferential surface of the sleeve to support a first side of the bearing; and   a snap ring installed on the inner circumferential surface of the sleeve to support a second side of the bearing.   
     
     
         5 . The muscle strength training apparatus of  claim 4 , further comprising:
 a plurality of waterproof covers each of which covers an end of the sleeve; and   a cover fitting detachably fixing each of the waterproof covers to the end of the sleeve,   wherein the cover fitting is composed of a snap ring installed on the inner circumferential surface of the sleeve to support a surface of each of the waterproof covers along an outer periphery of the waterproof cover.   
     
     
         6 . The muscle strength training apparatus of  claim 1 , wherein the connection part is composed of a fabric band having an upper portion to which the fixing part is integrally installed and a lower portion to which the handle is integrally installed, and having a vertical length,
 wherein the fabric band is made of a non-elastic fabric material, and   the fabric band has, at an upper end thereof, an upper fitting hole into which the hook of the fixing part is fitted and, at a lower end thereof, a lower fitting hole into which a stick of the handle is fitted, so that the hook is connected to the upper end of the band through the upper fitting hole and the stick is fixed through the lower fitting hole.   
     
     
         7 . The muscle strength training apparatus of  claim 1 , wherein the connection part comprises:
 a hollow cylinder having an upper portion to which the fixing pat is integrally installed; and   a lower cap coupled to a lower portion of the cylinder to close the lower portion of the cylinder,   wherein the handle is installed to the lower portion of the cylinder to which the lower cap is coupled.   
     
     
         8 . The muscle strength training apparatus of  claim 7 , wherein the connection part further comprises:
 an elastic body built into the cylinder and prevented from being separated by the lower cap;   a side member provided on a side of the elastic body for expansion and contraction of the elastic body; and   a lifting member having a first end connected to the side member and a second end connected to the handle, and raised and lowered by the handle,   wherein the lifting member vertically moves the side member by raising and lowering of the handle, thereby causing the elastic body to expand and contract through the side member.   
     
     
         9 . The muscle strength training apparatus of  claim 8 , wherein the connection part further comprises a spring seat protruding from the lower cap to support an outer circumferential surface of the elastic body,
 wherein the spring sheet supports the elastic body in close contact with the outer circumferential surface of the elastic body.   
     
     
         10 . The muscle strength training apparatus of  claim 1 , further comprising
 a stopper provided integrally with the crossbar or provided integrally with a post on which the crossbar is installed, and controlling a rotation angle of the fixing part rotatably installed on the crossbar.   
     
     
         11 . The muscle strength training apparatus of  claim 10 , wherein the stopper is composed of a bending stick bent and protruding from the crossbar, and controlling the rotation angle of the fixing part by catching the fixing part or the connection part through a protruding portion thereof. 
     
     
         12 . The muscle strength training apparatus of  claim 10 , wherein the stopper is composed of a barricade configured as a panel or a bar, fixed to an upper portion of the post at a higher position than the crossbar, and controlling the rotation angle of the fixing part by catching the fixing part or the connection part.
