  As shown in FIG. 1, the stretch exercise assisting tool 10 according to the present embodiment is composed of a rod body 10 a extending in one direction (the direction of reference sign “a” in FIG. 1). Both ends of the rod 10a are provided with a first end 11a and a second end 11b. The rod body 10a opens upward as shown in FIG. 2 in a cross section (for example, cross sections shown by reference signs A, B, and C in FIG. 1) perpendicular to the axial direction (direction of reference sign a in FIG. 1). The upper groove part 1, the back flat part 2 provided on the back side of the upper groove part 1, and the first back inclined part 3 a and the second back inclined part 3 b connected to both sides of the back flat part 2 are provided. Each of the first back inclined portion 3a and the second back inclined portion 3b is connected to the back flat surface portion 2 at an obtuse angle, and has a substantially V-shape.

Here, as shown in FIG. 2, the stretch exercise assisting tool 10 according to the present embodiment includes, for example, a first inclined portion 4 a and a second inclined portion 4 b connected to the first inclined portion 4 a. An upper groove 1 having an opening angle θ ₀ can be provided.

As illustrated in FIG. 3, the stretch exercise assisting tool 10 according to the present embodiment can perform a stretch exercise by placing the spine 21 in a supine position thereon, for example. And as shown to FIG. 4A, the back exercise | movement assisting tool 10 which concerns on this embodiment makes the back plane part 2 contact | abut on a floor, and the 1st back inclined part 3a and the 2nd back inclined part 3b contact | abut. The upper groove portion 1 is installed with the upper groove portion opened upward, and the back 20a of the person 20 is brought into contact with the uppermost portion of the upper groove portion 1 in a supine position. Then, for example, the buttocks are placed on the first end 11a or the second end 11b, and then the spine 21 is placed on the upper groove 1 in the order of the lumbar vertebra 21a and the thoracic vertebra 21b. At this time, the stretch exercise assisting tool 10 according to the present embodiment is first crushed near the upper end as shown in FIG. 4B, but as the load increases further, the opening angle θ ₀ increases as shown in FIG. 4C. growing. At the same time, the first back inclined portion 3a and the second back inclined portion 3b connected to both sides of the back flat surface portion 2 at an obtuse angle are also spread.

  The stretch exercise assisting tool 10 according to the present embodiment can repeatedly give contraction / relaxation stimulation to the spinal column standing muscle group by the repulsive force of the first back slope part 3a and the second back slope part 3b that are spread out. So the stretch effect can be enhanced.

  The stretch exercise assisting tool 10 according to the present embodiment is made of, for example, urethane foam or other elastic material, and twists the upper groove portion 1 around the axis of the rod body 10a (in the direction of symbol a in FIG. 1). Can be rotated. For this reason, it can be twisted and rotated while the spinal cord is housed in the groove during the stretching exercise.

  That is, as shown in FIG. 5A, when the spinal cord 21 is tilted leftward in the drawing, the stretch exercise assisting tool 10 according to the present embodiment follows the movement at an obtuse angle on both sides of the back plane portion 2. While the connected first back inclined portion 3a and second back inclined portion 3b are pushed and expanded, the torsional rotation is performed and the first back inclined portion 3a is inclined until it comes into contact with the floor. Conversely, as shown in FIG. 5B, when the spinal cord 21 is tilted to the right in the drawing, the stretch exercise assisting tool 10 according to the present embodiment follows the movement and obtuse angles on both sides of the back plane portion 2. While the first back inclined portion 3a and the second back inclined portion 3b connected in the above are pushed and spread, the torsional rotation is performed and the first back inclined portion 3b is inclined until it comes into contact with the floor.

  At this time, in the cross-section A, cross-section B, and cross-section C in FIG. 1, for example, the cross-section A is in the state shown in FIG. 4C, the cross-section C is in the state shown in FIG. It is assumed that it is in a state. As described above, the stretching exercise assisting device 10 according to the present embodiment follows the torsional rotation of the spinal cord while the first back inclined portion 3a and the second back inclined portion 3b are pushed and spread. Since it can be rotated, it is possible to perform stretching exercises in various postures as compared with a conventional stretch table. In particular, since the standing muscles of the spinal column run in a slightly oblique direction with respect to the spinal column, the stretching effect is further enhanced by performing an extension movement accompanied by the rotation of the spinal column.

As shown in FIG. 2, the stretch exercise assisting tool 10 according to the present embodiment can be configured such that, for example, the opening width W ₀ of the upper groove portion 1 is wider than the width W ₁ of the back flat surface portion 2. Thereby, the 1st back inclination part 3a and the 2nd back inclination part 3b which were connected to the both sides of the back plane part 2 at an obtuse angle are easy to be spread, and the stretch effect by these repulsive forces can be heightened. Specifically, the opening width W ₀ is 10 to 35 mm, and the width W ₁ is 10 to 20 mm.

In FIG. 2, the stretch exercise assisting tool 10 according to the present embodiment has, for example, a maximum width W _max of 50 mm or less and a maximum height H _max of 50 mm or less, and is excellent in portability. If the maximum width W _max is too narrow, a sufficient opening width W ₀ cannot be secured, so the lower limit is set to 30 mm. On the other hand, if the maximum height H _max is too low, a sufficient stretch effect cannot be obtained, so the lower limit is 20 mm.

  The stretch exercise assisting tool 10 according to this embodiment is made of, for example, urethane foam or other elastic material, and has a structure in which the rod body 10a can be bent. For this reason, for example, it is possible to stretch a muscle near the cervical vertebrae by the force of its own arm. That is, as shown in FIG. 6A and FIG. 6B, the first end portion 11a and the second end portion 11b of the stretch exercise assisting tool 10 according to this embodiment are respectively gripped by the left and right hands 20c, and the upper groove portion 1 is the back of the neck. In this state, the left and right hands 20c are moved forward of the body (in the direction toward the back of the paper surface in FIG. 6A, the right direction in the paper surface in FIG. 6B), thereby applying a pulling force. Thereby, the relaxation effect of the cervical vertebrae muscle group is obtained by supporting the cervical vertebra by the stretch exercise assisting device 10 according to the present embodiment, and the acupressure effect is also obtained by the moderate pressure action by the stretch exercise assisting device 10 according to the present embodiment. Obtained at the same time.

  Further, by shifting the relative positional relationship between the left and right hands 20c in the front-rear direction (the direction perpendicular to the paper surface of FIG. 6A, the left-right direction of the paper surface of FIG. 6B), it is possible to induce an appropriate rotation operation of the cervical spine. It becomes. Thereby, the relaxation effect of the cervical vertebra surrounding muscle group is obtained further.

  In addition, as shown in FIG. 1, it is preferable that the first end portion 11a and the second end portion 11b of the rod body 10a have a structure in which the upper groove portion 1 is closed so that it can be easily grasped by the left and right hands 20c.

  As mentioned above, in order to make explanation easy, the 1st back slope part 3a and the 2nd back slope part 3b which were connected to the both sides of the back plane part 2 at an obtuse angle, the 1st slope part 4a and the 2nd slope part which constitute the upper slot 1 Although 4b etc. are shown by the plane (a straight line in sectional drawing), it is not limited to such a structure. That is, changes can be made without departing from the above-described effects of the present invention. For example, each may be configured by a curved surface.

  According to the present invention, in the stretch exercise assisting device in which the groove capable of accommodating the spine is formed, the groove capable of accommodating the spine can be twisted and rotated, so that the spine is accommodated in the groove during the stretching exercise. It can be twisted and rotated.
