Bent over row machine

1 . A bent over row machine comprising:

a base frame placed to come in contact with the ground;

a main frame coupled to one side of an upper surface of the base frame and stands upright in a vertical direction;

a support unit fixed on the upper surface of the base frame, the support unit being configured to support a user's body, and to adjust an angle and a height of an upright position;

a pair of rotational movement units linked to the main frame and extending downward on both sides of the support unit;

a pair of handle units each linked to one end of each of the pair of the rotational movement units to allow the user to hold and rotate the rotational movement units while adjusting angles thereof;

a primary scaffolding unit placed at a slanted angle on the other side of the upper surface of the base frame, opposite the main frame, the primary scaffolding unit comprising a plate member to support the user's feet when the user is standing; and

a secondary scaffolding unit coupled to a side of the base frame to support the user's feet when the user is leaning on the support unit,

wherein the support unit includes:

a primary support seat configured to support the user's chest and abdomen;

a secondary support seat configured to support the user's hip;

a handle for folding the seats provided on a bottom surface of the secondary support seat;

a length-adjusting unit configured to adjust a height of the primary support seat and a distance between the primary and the secondary support seats;

a folding unit configured to fold the primary support seat and the secondary support seat toward the main frame; and

a damper provided to a side of the length-adjusting unit and configured to damp a movement of the primary support seat.

2 . The bent over row machine according to claim 1 , wherein the rotational movement unit includes:

a primary frame linked to the main frame and bent at a primary angle;

a secondary frame linked to an upper surface of the primary frame and bent at a secondary angle; and

at least one first mounting bar protruding from the primary frame and at least one second mounting bar protruding from the secondary frame, wherein the at least one first mounting bar fixes heavy goods to the primary frame, and the at least one second mounting bar fixes heavy goods to the secondary frame.

3 . The bent over row machine according to claim 1 , wherein the handle unit includes:

an angle adjustment plate linked to an end of the rotational movement unit with multiple angle adjusters;

a rotating shaft fixed to a side of the angle adjustment plate;

a primary handle provided in a bent pipe shape with an end thereof fixed to the rotating shaft;

a secondary handle provided in a bent pipe shape with an end thereof fixed to the rotating shaft; and

an angle fixing pin coupled to the rotation shaft to be rotated around the shaft and inserted into the angle adjuster to fix angles of the primary and secondary handles.

4 . The bent over row machine according to claim 1 , wherein the secondary scaffolding unit includes:

a length-adjusting frame axially coupled to the base frame; and

a scaffolding bar coupled to an end of the length-adjusting frame and extending normal to the length-adjusting frame.

5 . The bent over row machine according to claim 1 , wherein the damper is configured to raise the primary support seat while the length-adjusting unit adjusts the height of the primary support seat.

6 . The bent over row machine according to claim 1 , wherein the length-adjusting unit includes:

a primary adjusting frame linked to the folding unit;

a secondary adjusting frame linked to the primary support seat and movably inserted into the primary adjusting frame;

multiple length-adjusting holes provided on a surface of the secondary adjusting frame; and

a length fixing pin passing through a side of the primary adjusting frame and inserted into any one of the multiple length-adjusting holes to place the length-adjusting unit in a fixed state, and

wherein the damper is configured to raise the primary support seat for length adjustment, when the length-adjusting unit is released from the fixed state.

7 . The bent over row machine according to claim 6 , wherein the damper is linked to the primary support seat and the primary adjusting frame.

8 . The bent over row machine according to claim 1 , wherein the secondary support seat is configured to move along a longitudinal axis of the primary support seat using the length-adjusting unit, to adjust the distance between the primary and secondary support seats.

9 . The bent over row machine according to claim 1 , wherein when the primary and secondary support seats are folded toward the main frame by the folding unit, the primary support seat is placed between the pair of rotational movement units while being oriented horizontally, and the secondary support seat is oriented vertically such that the handle for folding the seats on the bottom surface thereof is exposed to the user to be gripped by the user.
