Weight training machine

Abstract

A weight training machine according to the present invention is a machine for conducting a dead lift or a bent over row while selecting and increasing/decreasing the weight, the machine comprising: a pair of body units, on which weight plates are stacked in the upward/downward direction, and which are provided on both sides of an operating unit, respectively; an operating unit, which is provided between the pair of body units, and which can move in the upward/downward direction; and a cable pulley unit for connecting the body units and the operating unit to each other such that, as the operating unit is moved in the upward/downward direction, the weight plates can be moved in the upward/downward direction, wherein, as the user operates the operating unit in the upward/downward direction and thereby moves the cable of the pair of cable pulley units, the user accordingly moves the weight plates on the body units, which are connected to the cable, thereby conducting weight training. The present invention, as described above, advantageously can provide a weight training machine, which is the purpose of the present invention, configured such that, when the exerciser wants to conduct a dead lift, a bent over row, etc., during weight training, the weight can be easily increased/decreased, and the basic postures can be easily learned, thereby reducing injuries.

1 . A weight training machine allowing weight to be increased or decreased by exerciser's selection and configured to perform weight training including a deadlift or bent-over row, the weight training machine comprising:
 a pair of body parts respectively installed at opposite sides of an operation bar, each body part comprising weight plates vertically stacked;   the operation bar installed between the pair of body parts to be vertically movable; and   a pair of cable pulley parts connecting the pair of body parts and the operation part to each other to enable the weight plates to be moved upward or downward according to upward or downward movement of the operation part,   wherein, when a user operates the operation bar upward or downward, cables of the pair of cable pulley parts are moved and, accordingly, the weight plates of each body part connected to the cable are moved upward or downward, thus enabling weight training.   
     
     
         2 . The weight training machine according to  claim 1 , wherein the operation part comprises:
 a machine fixing operation bar provided between the body parts and having a rod shape;   bar rings installed at lower portions of opposite sides of the machine fixing operation bar to allow the cables of the pair of cable pulley parts to be respectively connected thereto;   a pair of bar rail columns vertically installed at opposite sides of the machine fixing operation bar to allow the machine fixing operation bar to be moved upward or downward; and   column coupling parts coupled to opposite sides of the machine fixing operation bar, each column coupling part being provided with column transfer holes allowing the pair of bar rail columns to be inserted therethrough,   wherein one side and another side of the machine fixing operation bar are respectively connected to the cables of the pair of cable pulley parts, between the pair of body parts, to be movable upward or downward and, simultaneously, to enable the weight plates of each body part connected to the cable to be moved upward or downward.   
     
     
         3 . The weight training machine according to  claim 2 , wherein the column coupling part comprises:
 a pair of column couplers allowing the respective column transfer holes through which the bar rail columns are inserted to be separated;   a hinge coupled to an outer side surface of one side of each column coupler;   bolts passing through another side of the pair of column couplers; and   a nut coupled to one end of each bolt,   wherein, according to coupling between the bolts and the nuts, formation of a separation gap between an inner circumferential surface of the column transfer hole and an outer circumferential surface of the bar rail column is enabled, and a position at which the column couplers are coupled to the bar rail columns is adjustable.   
     
     
         4 . The weight training machine according to  claim 2 , wherein the body part comprises:
 weight plates each having a rod hole vertically passing therethrough at a center thereof, a plate holder groove at a side surface thereof, and column holes passing therethrough at opposite sides thereof to allow a pair of plate operation rail columns to be vertically installed therethrough;   a weight plate support allowing the weight plates to be stacked thereon;   a first pulley installed below the column coupler;   a second pulley installed between the weight plate support and the first pulley;   the pair of plate operation rail columns configured to pass through the weight plate support and guide the weight plates to be moved upward or downward;   a third pulley installed above the second pulley; and   a fourth pulley installed above the weight plates.   
     
     
         5 . The weight training machine according to  claim 4 , wherein each cable pulley part comprises:
 a fixing operation rod inserted into the rod holes of the weight plates and having rod plate fixing holes formed in a length direction of the fixing operation rod;   a fixing bar inserted into the plate holder groove of the weight plate and the rod plate fixing hole of the fixing operation rod to couple the weight plates to the fixing operation rod; and   the cable having one end coupled to an upper portion of the fixing operation rod and another end sequentially passing through the fourth pulley, the third pulley, the second pulley, and the first pulley to be coupled to the bar ring of the machine fixing operation bar via a cable hook,   wherein, when the machine fixing operation bar is moved upward or downward, the cable connected thereto moves the fixing operation rod upward or downward and, simultaneously, the weight plates coupled by the fixing bar are moved upward or downward, thus enabling weight training.   
     
     
         6 . The weight training machine according to  claim 1 , wherein the operation part further comprises:
 bar supports installed at lower sides of the machine fixing operation bar such that each bar support is installed at the body part via a bar support bolt to allow the machine fixing operation bar to be mounted on upper portions thereof,   wherein the bar support has bar column fixing grooves at an upper side surface thereof to allow lower ends of the bar rail columns to be inserted thereinto to fix the bar rail columns.
