BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a spine stretcher used to extend the spine of a human body.

[0002]

2. Description of the Related Art Conventionally, a spine stretcher used to correct or prevent the bending of the spine has a generally semicircular backrest surface, and the body should be laid on its back and the head to the tip of the foot should be kept in a solid contact. It is known to have been made.

[0003]

However, in such a conventional stretcher, since the spine is extended, the waist is bent at the same time, so that there is a drawback that the back is easily damaged. Further, in the conventional stretcher, the muscles and ligaments around the shoulder joint and the scapula cannot be effectively stretched.

[0004]

As a means for solving the above-mentioned problems, the spine stretcher of the present invention is provided with a handle member at one end and has a rigid substrate laid on the floor.
The backrest is placed on the substrate so that its position can be freely adjusted and supports only a small area of a part of the back.

[0005]

[Function] The user bends his / her knees and puts his / her feet on the floor, and lays on his / her back, and puts a small part of his back on the back support that is adjusted to the size of his body. Place only the area, extend the arm upwards and hold the handle member,
In this state, the bottom part is sunk.

As a result, the back is bent and the spine and pectoral muscles are stretched with the portion applied to the back support as a fulcrum. On the other hand, the lower back portion does not warp while being bent, so there is no risk of back injury.

[0007] Further, if the user holds the holding member with one hand and shifts the body laterally so as to form an angle with the arm holding the holding member, and in that position the hip portion is sunk in the same manner as described above. , The part from the chest to the arm is stretched back.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIG. As shown in FIG. 1 (A), the stretcher of this embodiment comprises a substrate 1 and a back support 3.

The substrate 1 has a substantially rectangular shape with a length of 1 m and a width of about 7 to 80 cm, and is made of a highly rigid material so as not to be easily bent. The handle member 2 is attached to one end of the substrate 1. There is.

The back support 3 is formed in a roll shape having a diameter of about 30 cm and a length slightly longer than the width of the substrate 1.
The surface is covered with elastic material.

Next, a method of using this embodiment will be described. As shown in FIG. 1B, the substrate 1 is laid on the floor a.
Place the back support 3 on top. The user, as shown in the figure,
With the knees bent and the legs affixed to the floor a, the back is placed on the back support 3, the arms are extended upward, and the handle member 2 is held.
have. At this time, the position of the back support member 3 is adjusted while rolling on the substrate 1 so that the back support member 3 hits the back of the part away from the waist.

When the hip portion is sunk from that posture, the back is warped with the portion applied to the back support 3 as a fulcrum, and the spine, particularly the upper thoracic vertebra and pectoral muscles are stretched. On the other hand, the lower back portion does not warp while being bent, so there is no risk of back injury.

Those who feel sick when their heads go down are
A pillow 4 may be applied as shown by the chain line in the figure.

Further, as shown in FIG. 1C, the holding member 2 is held by one hand, and the back support 3 is placed so as to make an angle between the body and the arm holding the holding member 2. If you slide it sideways with and sunk the hips as above, the part extending from the chest to the arm will be warped, and the shoulder joints, pectoralis major muscles, pectoralis muscles, biceps and forearm flexion groups will be effective Can be extended to.

[0015]

[Effect of the Invention] As described in detail above, by using the stretcher of the present invention, the back support is applied to only a small area of the back and the hips are sunk, so that the waist is not warped. Since the back can be bent, the back and pectoral muscles can be effectively stretched while preventing the induction of back pain.

Further, if the user stretches the body while holding the holding member with one hand so as to make an angle between the body and the arm, it is difficult and difficult to perform the conventional stretching. The shoulder joints, pectoralis major muscles, pectoralis minor muscles, biceps and forearm flexor muscles can be extremely extended.

Moreover, since the backrest is freely position-adjustable, it can be used by anyone, young or old, by adjusting the position according to the size of the body or the like.
