Description

  The present invention relates to a small and lightweight abdominal muscle exercise assisting device for performing abdominal muscle exercises easily and comfortably.

  In order to strengthen the abdominal muscles, so-called abdominal muscle exercises, such as exercises that raise the upper body while taking a posture such as placing hands behind the head or holding them in front of the body without using instruments, exercises that raise the legs, etc. Yes. In order to enhance the effect of this exercise, a method of applying a larger load by using a tilt table (bench) is also generally used. On the other hand, it has been pointed out that the exercise of raising the body, which was generally performed until a long time ago, has the risk of causing back pain due to excessive strain on the hips when stretched with the knees stretched, and is now performed with the knees bent. Consideration is also required to ensure that exercise is carried out without unreasonableness.

For the reasons described above, an abs exercise assisting device has been proposed. For example, Japanese Unexamined Patent Application Publication No. 2009-254552 (Patent Document 1) includes a central member sandwiched between both knees of a user, a base bar positioned on both thighs, and a handle bar provided on the central member. By pulling the handlebar with both hands, the abdominal muscles exercise while borrowing the strength of the arm.
However, many people who do not exercise much, women who do not have enough muscle strength, and elderly people complain of neck fatigue and pain when performing abdominal exercises. This is due to the burden on the neck and the burden on the weight of the head when performing abdominal exercises. Also, those who do abdominal exercise tend to bend the cervical spine excessively, which also burdens the neck. The conventional technology (Patent Document 1) can assist the abdominal muscle movement of a person whose arm strength is insufficient by borrowing the strength of the arm, and can also train the muscles of the arm and thigh, but is expected to reduce the burden on the neck Can not.

  An object of the present invention is to solve the above problems by providing a small and lightweight abdominal exercise assisting tool that reduces the load on the neck that supports the head accompanying abdominal exercise and is easy to carry. .

  In view of the conventional problems as described above, the present invention has the following configuration. That is, the present invention is composed of a substrate having a cushion layer provided on a surface in contact with the user's body and belts provided on both the left and right sides of the substrate, and the user pulls the belt forward of the body and the upper back portion. An abdominal muscle exercise assisting device is configured to be installed on the back of the head.

  The substrate of the present invention preferably has a rectangular shape, a polygonal shape, an elliptical shape or the like, and can cover the back of the human body from the upper back to the upper back, and the size is preferably A4 to B4. The material of the substrate is preferably wood, resin product, paper molded product, metal plate, FRP or the like.

The cushioning material of the present invention is a foamed resin, for example, polyurethane, and a material in which a polysilicon resin, a melamine resin, a cellulose resin, cotton, or the like is enclosed in a bag as another material can be used.
The belt of the present invention can be made of cloth, towel cloth, leather, synthetic leather, an aggregate of ropes, etc. The length when stretched forward of the body when used is 25-40 cm from the left and right sides of the substrate, respectively. Preferably there is. The thickness of the belt is preferably grasped lightly by hand, and the circumference is preferably 6 to 12 cm.

 The exerciser uses the left and right belts while pulling lightly and fixing the assisting device to the upper back. The abdominal muscle exercise assisting device of the present invention is preferably characterized in that the belt is connected to the substrate via a belt loop provided at substantially the center on both the left and right sides of the substrate. About the center is the place where the neck of the human body is located on both sides of the abdominal exercise assisting device of the present invention.

  The abdominal muscle exercise assisting device of the present invention is an abdominal muscle exercise assisting device having a ring formed by folding both ends of the belt. It is preferable that the user has a structure in which the belt is lightly pulled forward of the body by passing the hand through the rings provided at both ends of the belt, and the auxiliary tool is fixed to the upper back.

  The abdominal muscle exercise assisting device of the present invention has a thickness at the center of the substrate of 1.5 to 3 cm thicker from the lower end and a thickness of the lower end of 0.1 to 1 cm, and has a gentle curved surface from the outer center to the lower end of the substrate. It is preferable to be characterized by this.

  The abdominal muscle exercise assisting device of the present invention is characterized in that the upper half of the cushion layer is thicker than the lower half, and the upper half is in contact with the back of the head and the lower half is in the upper back when used. It is preferable that the structure be in contact with. The back of the head is almost hemispherical and is smaller in size than the upper back. Therefore, if the cushion layer is thin, there is discomfort and the position is difficult to stabilize. In addition, the position of the occipital region during abdominal exercise tends to tilt slightly forward relative to the upper back. Considering such a state, the auxiliary tool can be more appropriately installed by making the upper half cushion layer thicker than the lower half.

Since the present invention is configured as described above, the following effects can be obtained.
The invention according to claim 1 is an abdominal muscle exercise assisting device constituted by a substrate and a belt formed by providing a cushion layer on the surface of the substrate that contacts the user's body. It is applied so as to bridge the back of the user's back and upper back, and the assisting tool is fixed to the upper back by gently pulling the belt forward with the left and right hands, giving the neck and upper back a sense of unity. As a result, it is difficult to apply an extra load to the neck muscles and tendons that support the head, and it is possible to reduce the feeling of fatigue and pain in those portions. Therefore, a person with weak physical strength can easily perform abdominal exercises in the neck. Moreover, it is not a complicated structure but is a small and lightweight auxiliary tool that is easy to carry.

  According to the second aspect of the present invention, belt belts are provided on both the left and right sides of the board, and the belt is pulled from the outside to the body side so as to wrap the board from the outside during use. Even if the pulling force is weak, the auxiliary tool can be properly fixed to the upper back, and an extra load on the neck can be avoided. Furthermore, since the belt is connected to the substrate through a belt loop, it can be detached except during use, and it is easy to remove dirt such as sweat due to exercise.

  The invention according to claim 3 is a structure having a ring formed by folding both ends of the belt, and in use, the belt can be pulled in front of the body with a slight force by putting a hand into this and grasping it lightly. Because you can, you can do abdominal exercises easily without straining your hands and arms. Further, if the above folding is released, there is an advantage that the belt can be easily removed from the belt loop.

  The invention described in claim 4 has a structure in which a gentle curved surface is provided on the outside of the substrate, that is, a surface that does not contact the body, and the lower end portion is thin. Therefore, since the assistive device sandwiched between the back and the floor has the above structure even when lying on the floor during use, the back does not feel uncomfortable and does not feel pain, so the abs I can exercise.

  According to the fifth aspect of the present invention, the cushion layer in the part in contact with the back of the head has a thicker structure than the cushion layer in the part of contact with the upper back, and the cushion catches the back of the head with a curved surface, so the positions of the back of the head and the upper back are suitable. To keep the neck angle constant. Therefore, the strength around the neck can be taken, the fatigue and pain of the neck can be reduced, and the abdominal muscles can be exercised easily.
