Thereby, the user can perform the stretching exercise of the body relatively safely and comfortably.

Here, the structure and function of the present invention will be described in detail with reference to the drawings, showing a relatively preferred embodiment. Among them, the drawings to be used are first briefly described as follows.
Please refer to FIG. 1 and FIG. An extension training machine provided by a relatively good embodiment of the present invention includes the following.
The pedestal 10 is a body which is placed in parallel on the ground and has a shape of "K", and is vertically connected to the middle position of one front horizontal bar 11, the rear horizontal bar 12, and the two horizontal bars 11, 12. It is composed of a bottom bar 13. In this embodiment, the bottom bar 13 is a square telescopic tube set, and the front horizontal bar 11 can move in the front-rear direction while facing the rear horizontal bar 12 (as indicated by the imaginary line in FIG. 2). ). The position of the front horizontal bar 11 is fixed by positioning components (bolts) 14 provided on the bottom bar 13. A seat 15 protrudes above the bottom bar 13. A pair of pulleys 16 are provided inside the both ends of the front horizontal bar 11 and the rear horizontal bar 12, respectively. A footrest 17 is separately provided at the upper end of the front horizontal bar 11.

The main bar 20 is a rectangular telescopic tube set in the present embodiment, and a positioning component (bolt) 25 is provided on the right side surface of the main bar 20 to position the main bar 20 at a distance where the upper end faces the bottom end. . The bottom end of the main rod 20 is pivotally mounted on the seat 15 of the bottom rod 13, the shaft pin 21 is pivotally mounted on the seat body 15 and the bottom end of the main rod 20 in the left-right direction. It can rotate along the front and rear direction. The bar of the main bar 20 extends obliquely upward and backward from the pedestal 10. A first sleeve 22 having a left-right axial direction and a second sleeve 23 located below the first sleeve 22 are fixedly provided on the front side surface of the main rod 20. In the first sleeve 22, a shaft bar 26 extending in both left and right outer directions is provided. The shaft 26 can be freely removed from the first sleeve 22 and can be separately bored in the second sleeve 23. At a position slightly higher than the first sleeve 22 on the rear side surface of the main rod 20, a third sleeve 24 having a left-right axial direction is provided.

The backrest 30 is a rectangular cushion whose outer periphery is covered with a soft material, and a seat 31 is provided at a central position on the back surface. The backrest 30 has a seat body 31 pivotally provided at an upper end of the main rod 20, and a shaft pin 32 is bored in the seat body 31 and the upper end of the main rod 20 in the left-right direction. As the center of rotation, the main rod 20 rotates along the front-rear direction (as indicated by the imaginary line in FIG. 2), and usually assumes the state of FIG. 2 by its own weight.

The seat 40 has a chair cushion 41 and two parallel fixing bars 42 provided at a predetermined interval on the bottom of the chair cushion 41. The rear ends of the two fixing rods 42 project toward the rear side of the chair cushion 41 and are respectively installed on the left and right sides of the main rod 20. Further, a shaft pin 43 is formed in the rear ends of the two fixing bars 42 and the third sleeve 24, and the two fixing bars 42 face the front side of the main bar 20, and the bottom surface abuts on the shaft bar 26. A seat portion 40 is pivotally mounted on the main bar 20 so as to maintain a predetermined angle with the main bar 20 so that the chair cushion 41 is located on the front side of the main bar 20. By inserting the shaft bar 26 onto the first or second sleeve 22, 23, the seat 40 can be adjusted to a different angle on the main bar 20.

The bottom end of the spring rod 50 is pivotally mounted on the bottom rod 13 of the pedestal 10, and the pivot point is located on the rear side of the main rod 20. At the upper end, a removable fixing pin 51 is drilled on the rear side of the main bar 20. A spring bar 50 is provided obliquely between a position near the bottom of the main bar 20 and the pedestal 10, and makes the main bar 20 elastic. Supported by.

The two elastic ropes 60 are provided on the left and right sides of the pedestal 10 along the front-rear direction, respectively, and are drilled in the corresponding pulley sets 16. One ring 61 is provided at each end of each elastic rope 60. The ring-shaped receiving portion 62 can be removed, and the user can select and attach it to the ring 61 in front of or behind the elastic rope 60. The two force receiving portions 62 can be gripped by both hands of the user or can be hooked by both feet.

With the above-described structure, the user first adjusts the footrest portion 17 and the backrest 30 to a position compatible with the body shape by utilizing the characteristic that the main bar 20 and the bottom bar 13 of the pedestal 10 can expand and contract. The following training exercises can be performed.
1. As shown in FIG. 4, the back is pressed against the backrest 30 and both feet are hooked on the footrests 17 of the pedestal 10. Then, the body is supine using the pivotal movement of the backrest 30 to extend the body backward. The effect is achieved, and the user can extend and train the muscles of the back and abdomen.

2. As shown in FIG. 5, the user sits on the seat 40, grasps the force receiving portion 62 provided at the rear ends of the two elastic ropes 60 with both hands, and holds the elastic rope 60 on the front side of the body. Extend diagonally upward. In this way, the muscles of the shoulder can be trained.
3. As shown in FIG. 6, the user sits on the seat portion 40, grasps the force receiving portion 62 provided at the front ends of the two elastic ropes 60 with both hands, and pulls the elastic rope 60 upward. In this way, the muscles of the shoulders or arms can be trained.

4. As shown in FIG. 7, the user sits on the seat 40, steps on the front cross bar 11 with one foot, passes the other foot through the force receiving portion 62 at the front end of the elastic rope 60, and When the rope 60 is pulled upward, the thigh muscles can be strengthened.
5. As shown in FIG. 8, the user directly steps on the rear horizontal bar 12 of the pedestal 10, pulls the two elastic ropes 60 upward with both hands, and achieves the effect of training the muscles of the hands and arms. be able to.

6. The user presses the back part on the backrest 30, hooks both feet on the footrest part 17, holds the force receiving part 62 provided at the rear end of the two elastic ropes 60 with both hands, and pivots the backrest 30. If the user performs a stretching motion on the back of the body by simultaneously pulling both arms upward or to the left and right, the two types of muscles can be simultaneously trained.
In addition, the user presses the abdomen on the backrest 30 in such a manner that the user stomps the body from back to front, grips the footrest 17 of the pedestal 10 with both hands, and holds the abdomen and arms in a posture similar to push-ups. You can also exercise to train your muscles.

When the user does not train, as shown in FIG. 3, the main rod 20 and the bottom rod 13 of the pedestal 10 are stored in the shortest state, then the fixing pin 51 of the spring rod 50 is pulled out, and the spring rod 50 is removed. Is folded so as to be parallel to the pedestal 10, then the main bar 20 is rotated to the folded position, and finally the shaft bar 26 is pulled out so that the seat portion 40 assumes a state parallel to the main bar 20. Can be folded.
As described above, the present invention allows the user to operate relatively safely and comfortably, and the user can perform various training exercises to achieve the effect of the whole body exercise.
