Hip-up exercise apparatus

Abstract

According to the present disclosure, provided is a hip-up exercise apparatus. The hip-up exercise apparatus includes a frame defining an opening at one side thereof and fixing holes at both sides of upper surfaces thereof; a footrest portion disposed at the opening of the frame; a pair of pillars inserted into and coupled to the fixing holes of the frame; and a back supporter connecting upper portions of the pair of pillars and configured to support a back; and the pillars are separated from the fixing holes, are rotated downward, and are turned over, to attach rear surfaces of the pillars to upper surfaces of the frame. The pillars are separated from the fixing holes, are rotated downward, are turned over, and protrusions are coupled to the fixing holes, to attach the rear surfaces of the pillars on the upper surfaces of the frame, and the footrest is moved inside the frame to a maximum position thereof through the rail, thereby minimizing volume of the hip-up exercise apparatus, facilitating storage of the hip-up exercise apparatus, and conveniently using the hip-up exercise apparatus at home.

 wherein the first through-hole is defined at the lower portion of the pillar and the protrusion,   wherein the frame defines the second through-hole communicating with the first through-hole when the lower portion of the pillar and the protrusion are each inserted into the fixing hole, and   wherein the first through-hole is eccentric to one side of the pillar from a center of the pillar in a longitudinal direction of the pillar and the second through-hole is eccentric to the one side of the frame from a center of the frame in a longitudinal direction of the frame.   
     
     
         5 . The hip-up exercise apparatus of  claim 2 , further comprising; a connector connecting the pair of pillars and disposed below the back supporter,
 wherein a lower surface of the connector contacts the upper surface of the frame when the lower portion of the pillar is inserted into the fixing holes,   wherein a rear surface of the connector contacts the upper surface of the frame when the protrusions is inserted into the fixing hole,   wherein the lower surface and the rear surface of the connector are each supported by the upper surface of the frame when the pillar is coupled to the fixing hole in a vertical state or a folded state to inhibit swinging of the pair of pillars and increase a force for coupling the pillars to the frame.   
     
     
         6 . The hip-up exercise apparatus of  claim 2 , further comprising a hook disposed at a middle portion of the upper surface of the frame, contacting an upper surface of the pillar when the protrusion is inserted into the fixing holes of the frame and configured to couple to a strap;
 wherein, when the rear surface of the pair of pillars is attached to and coupled to the upper surface of the frame, an upper end of the pair of pillars contacts the hook and the pillar is disposed between the hook and the fixing hole.   
     
     
         7 . The hip-up exercise apparatus of  claim 3 , wherein the rail portion comprises:
 a first rail inserted into the insertion groove,   a lever disposed at one side of the first rail, having a first end rotatable about a first hinge and a second end protruding in one direction of the first rail,   an engaging portion disposed at a middle portion of the first rail and rotatable about a second hinge,   a link member connecting the lever and the engaging portion and moved in a rotational direction thereof when the lever rotates about the first hinge,   a second rail facing the link member, slidable in a longitudinal direction of the first rail, and defining, at one side thereof, a first engaging protrusion caught by the engaging portion and configured to inhibit separation from the first rail, and a third through-hole at a second side thereof,   a rotating member disposed at the second side of the second rail, rotatable about a third hinge, defining an insertion protrusion inserted into the third through-hole, protruding vertically, rotatable by a vertical width of the third through-hole, defining a middle portion thereof having a vertical width increased toward a second end of the second rail from the third hinge and contacting a second end of the first rail and rotated when the first rail slides into the second rail, and disposed between an upper portion and a lower portion of the first rail, and   a third rail facing the insertion protrusion of the rotating member, slidable in a longitudinal direction of the second rail, and defining a second engaging protrusion at a middle portion thereof, and when the first rail is separated from the rotating member, the rotating member rotates and the insertion protrusion is caught by the second engaging protrusion and when the rotating member is disposed between the upper portion and the lower portion of the first rail, the second engaging protrusion passes through the insertion protrusion.   
     
     
         8 . The hip-up exercise apparatus of  claim 7 ,
 wherein the lever defines a third engaging protrusion protruding toward the third rail at a middle portion thereof,   wherein the third rail defines a fourth engaging protrusion protruding toward the second rail at a first side thereof and being caught by the third engaging protrusion and a supporting protrusion protruding toward the second rail at a second side thereof,   wherein, when the second rail slides into the third rail and the first side of the first rail slides to the first side of the third rail, the third engaging protrusion is caught by one end of the fourth engaging protrusion, and when the lever is rotated, the third engaging protrusion passes through the fourth engaging protrusion, and   wherein the third engaging protrusion passes through the fourth engaging protrusion and the second end of the first rail slides to and is supported by the supporting protrusion of the third rail, and when the rotated lever is returned back to original position thereof, the third engaging protrusion is caught by a second end of the fourth engaging protrusion to couple the first rail to the second rail and the third rail in an overlapped state.   
     
     
         9 . The hip-up exercise apparatus of  claim 7 ,
 wherein the engaging portion defines an engaging groove into which the first engaging protrusion is inserted,   wherein, when the first rail is taken out from the second rail and the first engaging protrusion is inserted into the engaging groove, the first rail and the second rail are coupled to each other in the taken-out state, and   wherein, when the lever rotates, the link member moves in the first direction of the first rail and the engaging portion is rotated about the second hinge and the first engaging protrusion is separated from the engaging groove to slide the first rail and the second rail.   
     
     
         10 . The hip-up exercise apparatus of  claim 7 ,
 wherein the third rail defines fifth engaging protrusions protruding from a upper surface and a lower surface at a first side thereof,   wherein the second rail defines sixth engaging protrusions protruding from an upper surface and a lower surface thereof and protruding between the second engaging protrusion and the fifth engaging protrusion, and   
       wherein, when the second rail slides in one direction thereof, the sixth engaging protrusion is caught by the fifth engaging protrusion to block the separation of the second rail from the third rail.
