Therefore, since muscle training must be appropriate, safe, and efficient, it is necessary to be able to train each muscle in each part of the human body appropriately. Therefore, there are many types of training equipment of this type, each having unique configurations and effects. These devices consist of springs, weights, or equipment that generates pressure that applies constant or variable loads to muscles, and these devices are used by trainers as appropriate to train muscles in desired areas. It is. For example, a so-called abdominal training device is known as a device that can train the oblique muscles of the human body, but this is configured like a sitting device that fixes the lower body of the human body and allows the upper body to twist. It was hot.

Problems that the invention aims to solve According to the conventional abdominal training device described above, when doing upper body twisting exercises, there is no member to stably support both arms, so the upper body tends to become unstable. Training requires skill, which makes it difficult to conduct effective training. Furthermore, when performing upper body twisting exercises, there is no loading device to make the exercise more effective, and the exerciser simply twists his or her body, which does not provide sufficient training. good.

In view of the above circumstances, this invention has a means for stably holding the upper body and a loading device that makes twisting movements effective, so that the abdominal oblique muscles can be effectively trained. The purpose of this invention is to provide an abdominal oblique muscle training device that allows even an amateur to train extremely easily without requiring training.

Next, to explain the operation of the above-mentioned embodiment, the trainee first lowers his/her hips to the seat board 2, sits down, places both feet on the foot rest arms 4, and secures them with the foot holding pads 6. . Next, as shown in FIG.
7 to the left (direction of arrow A in Figure 9), pin 50
After protruding from the through hole 53 of the disk 51 and fitting it into the through hole 54 of the sheave 44, place the back against the back pad 10 and press the chest pad 1 with both arms.
Hold 2, 12 and press it against your chest. In this state, bend your upper body forward. When the upper body is bent forward, as shown in FIG. 9, the rotating arm 9 rotates forward about the pivot parts 7, 7,
The sheave 44 rotates clockwise (direction of arrow A),
The wire 42 connected to the sheave 44 is wound up (in the direction of arrow A), and the shaft 23a rotates clockwise in the figure (in the direction of arrow A). When the shaft 23a rotates clockwise, the sprocket 24a rotates in the same direction, moving the chain belt 22 in the direction A indicated by the arrow. Therefore, the sprocket 21a rotates clockwise (direction of arrow A) about the shaft 20, the sprocket 21 rotates counterclockwise, the shaft 20 rotates in the same direction, and the seat plate 2 rotates counterclockwise ( direction of arrow A). Further, the chain belt 22 rotates the shaft 23 counterclockwise (in the direction of arrow A) via the sprocket 24. Therefore, the arm 23c shown in FIG. 5 contacts the stopper 25c and rotates the sheave 25a in the same direction (direction of arrow A). On the other hand, the arm 23b rotates in a direction away from the stopper 25b. When the sheave 25a rotates in the same counterclockwise direction as the shaft 23, the sheave 29a of the shaft 30a is rotated clockwise (in the direction of arrow B) via the wire 28a.
This causes the cam 31a to rotate in the same direction. When the cam 31a rotates clockwise, the wire 32 is wound around the cam 31a, the sheave 35 attempts to descend, and the cam 31 is rotated counterclockwise. When the cam 31 rotates counterclockwise, the sheave 9 winds the wire 28 and the sheave 25
Rotate counterclockwise. However, in FIG. 5, the stopper 25d of the sheave 25 comes into contact with the stopper 1a, and the rotation of the sheave 25 is prevented.
Then, the wire 28 is tensed and the rotation of the sheave 29 is prevented, and therefore the rotation of the cam 31 is prevented, so the weight 39 is lifted and its weight is applied to the rotating arm 9, causing the upper body to move forward. While rotating, the lower body is forcibly twisted to the left around the abdomen via the seat plate 2.

In addition, tilt the handle lever 47 to the right (9th
(in the direction of arrow B in the figure) and move in the opposite direction to the above, the seat plate 2
rotates clockwise. That is, the disk 51
a and the sheave 44a are integrated, the wire 42 is wound up, the sheave 26a is rotated counterclockwise (in the direction of arrow B), and the sprocket 24a is rotated.
are rotated in the same direction and the chain belt 22 is moved in the direction of arrow B, so the seat plate 2 is rotated clockwise (direction of arrow B) and the sheave 25 is rotated in the same direction.
The rotation of the wire 2 is prevented by the stopper 1b.
8a becomes tense, and the weight of the weight 39 is loaded onto the rotating arm 9. Also, when the handle lever 47 is tilted in this way, the
The position where the ball 48a shown in the figure abuts against the circumferential surface of the handle lever 47 changes, and the ball 48a protrudes and retracts from the hole 46 to fix the leftward and rightward tilted positions of the handle lever 47, respectively.

Effects of the invention According to the invention described above, the seat plate, which can freely rotate left and right, and the rotating arm equipped with the chest arm are linked, and the left and right rotation of the seat plate can be changed arbitrarily through the switching part of the load mechanism. By simply bending the upper body forward, the selected load of the loading mechanism is applied against the bending movement, and the lower body is forced to move to either the left or right side. Since it rotates in this direction, you can effectively train your oblique muscles. In addition, it is possible to hold the pair of chest pad arms with pads and to put your back in contact with the back pads, so the upper body of the trainee is stably held by the rotating arms, while the legs are held by the foot rest arms and the feet. Since the lower body is fixed with a presser pad, the lower body is stably held on the seat plate, and the upper and lower body are held separately, so that twisting movements can be performed effectively. Therefore, the training of the abdominal oblique muscles, which conventionally required skill, can be performed easily, safely and appropriately even by an amateur.
