DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a muscle training apparatus, and more particularly to an improvement of a muscle training apparatus known as a high pulley training machine.

[0002]

2. Description of the Related Art A high pulley training machine is a muscular strength training device used for muscular training of the pectoralis major (lower part), biceps brachii, latissimus dorsi, triceps brachii and great circle muscle.

In a conventional high pulley training machine, as shown in FIGS. 6 to 8, a weight suspension frame 2 is suspended from one end of a frame 1 placed on a floor or the like. The seat 3 is fixedly supported at a predetermined height at the other end of the frame 1 so as to face the wire rope 6 via a pulley 5 to an arm 4 reaching almost directly above the seat 3 from above the frame 2. A wide grip handle 7 is connected to the lower end of the wire rope 6, and the other end is extended into the frame 2 and connected to a weight connecting tool 8. A desired number of weights 9 appropriately selected can be attached to and detached from the weight connecting tool 8. In addition, a knee pad 10 whose height can be adjusted is provided in front of the seat 3.

A person who exercises muscles with this high pulley training machine adjusts the height so that the user sits on the seat 3 and presses the thighs against the knee pad 10, and raises both arms to raise both ends of the wide grip handle 7. The weight rope 8 is lifted up and down by the wire rope 6 being lifted up and down by the weight suspension frame 2 by grasping the arm and raising and lowering both arms in front of or behind the chest. As a result, a load of the weight 9 having the set weight is generated, and the wide grip handle 7 performs a raising and lowering motion while resisting the force of returning to the original position by the weight of the set weight 9, and thereby the predetermined portion is He was able to train his muscles.

[0005] As a method of exercise, there are a front pull-down that raises and lowers the wide grip handle 7 in front of the chest of the strength trainer, and a back pull-down that raises and lowers the wide grip handle 7 behind the strength trainer.

[0006]

However, according to the conventional high pulley training machine described above, since the seat 3 is of a fixed installation type, the upper body is required at the time of front pull-down as shown by the dashed line in FIG. He had to lean backwards, so he could not maintain his posture without putting much effort into his abdominal and back muscles in addition to his intended latissimus dorsi. In addition, during back pull-down, the upper body must be forcibly tilted forward as shown by the two-dot chain line in FIG. Have been unable to exercise effectively on the whole.

[0007] Therefore, beginners are not accustomed to
As a result of raising and lowering the wide grip handle 7 on the front and back without moving the upper body, the face and the back of the head may be abraded by a wire rope.

Therefore, the present invention is to improve a high pulley training machine in order to solve the above problems.

[0009]

A muscle strength training apparatus according to the present invention provides a muscle training at a predetermined site by gripping a grip handle loaded with a weight with both hands and performing a front pull-down or back pull-down exercise. In the strength training apparatus, the seat positioned substantially immediately below the grip handle can be moved back and forth with respect to a frame to which the seat is fixed , and via a lock mechanism.
The adjustment position is provided so as to be fixable . Further, the seat is characterized in that a mounting plate on which a seat pad is mounted and fixed is engaged with the frame so as to be movable back and forth, and is in sliding contact with a roller rotatably supported by the frame.

Therefore, when performing front pull-down or back pull-down exercises, the seat is adjusted back and forth to move the body before or after vertically below the grip handle, and then the adjustment position is fixed via the lock mechanism. Do
Thus , training can be performed at a position where the wire rope is vertical.

[0011]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings. As shown in FIGS. 1 to 5 , a weight suspension frame 2 corresponding to the weight suspension frame 2 of the above-described conventional example is provided at one end of a frame 20 of a predetermined length placed on a floor or the like.
1, a seat 22 is disposed on the frame 20 so as to be movable in the front-rear direction relative to the frame 21.

That is, both ends of the inner pipe 36 having a predetermined length are fixed to the supporting member 2 having a predetermined height in the vicinity of the end of the frame 20a horizontally supported at a predetermined height from the frame 20.
0b and supported horizontally, and the inner tube 36 is connected to the outer tube 35.
Are fitted movably in the longitudinal direction, a seat plate 34 is fixed to the outer tube 35, and a seat pad 33 is stretched on the seat plate 34. Further, a support 3 is provided on both sides of the frame 20a.
0 and 30 are connected to each other by welding or the like, and the shafts 31 are protruded in the horizontal direction and fixed to the supports 30.
1, a roller 32 is rotatably supported. Roller 3
2 is in sliding contact with the lower surface of the seat plate 34.

Therefore, when the trainee sitting on the seat pad 33 moves his waist, the seat plate 34
, The seat pad 33 can be moved back and forth by a predetermined distance, and the position of the seat 22 can be adjusted. Although not shown, it is possible to easily add a lock mechanism for fixing the moving position of the seat plate 34 and preventing the waist from swaying.

The seat 22 supports knee pads 23, 23 corresponding to the conventional knee pads 10, 10 so as to be adjustable in height. The arm 24 is overhanging almost right above the seat 22.
Numeral 4 is supported on the upper part of the weight suspending support frame 21, and its base is supported by a column 25 erected in parallel with the weight suspending support frame 21. A wide grip handle 28 is connected to a lower end of a wire rope 27 that hangs from a pulley 26 that is pivotally supported at one end of the arm 24. The wide grip handle 28 can be replaced with a press-down bar (not shown), and these are collectively referred to as a grip handle in this document.

The wire rope 27 is used for the weight suspension frame 2.
1, the pulley 26 is suspended from the upper part of the frame 21 via a pulley 26 via a pulley 26 a pivotally supported on the upper part of the frame 21, and a weight connecting tool 40 is connected to a lower end of the frame 21. The weight connecting tool 40 is a known one in which a desired number of weights 41 are appropriately selected and detached with a pin. The weight 40 is a publicly known one that can be moved up and down along guide rods 42, 42 suspended in the frame 21. Weight 4 1 the frame 2
Resin cover 43 provided substantially surrounding the lower part of 1
Shielded by Reference numeral 45 denotes a plate for explaining how to use.

Therefore, a person who exercises strength with the above-described high pulley training machine sits on the seat 22, adjusts the height so that the knees hit the knee pads 23, 23, and sits down. In this case, the foot pad placed on the floor is stepped on, and the waist is pushed forward or pulled out as shown by a chain line in FIG. Is moved back and forth to adjust the position of the seat 22. After that, raise both arms upward and hold both ends of the wide grip handle 28 with both hands,
Repeat the exercise of raising and lowering while bending both arms.

[0017]

According to the present invention described above, since the seat can be moved back and forth and the position thereof can be fixed , the seat can be adjusted without any excessive posture in either the front pull-down or the back pull-down. Since the training can be performed with the wire rope suspending and supporting the grip handle in a vertical state, effective strength training can be performed in an appropriate posture without rubbing the face or the back of the head with the wire rope.
