It is a cylindrical shape with cushioning properties, or a cylindrical shape with a cushion layer on the surface and a cylinder made of a hard material as the core, and is used by the user along the guide surface. In order to perform squat exercise while keeping the back surface parallel to the guide surface so that the person's upper body does not lean forward, the rotation axis is sandwiched horizontally between the user's back and the guide surface. The surface of the soft material, which acts to support the back of the user who bends and stretches while rolling, and forms the cylindrical cushion and the cushion layer of the cylindrical surface, which is in contact with the back and the vertical guide surface, is molded. It is a squat exercise assisting device that has been processed to prevent slipping such as uneven shape patterns and satin finish.

FIG. 1 is an overall view of a one-cylindrical rotating body cushion which is a cylindrical type of the present instrument. It is a cylinder made of a soft material with moderate elasticity such as urethane foam. The size of the cylinder is between 8 cm and 20 cm in diameter, and the length is between 20 cm and 40 cm for ease of use. Moderate elasticity is elasticity that is not stiff enough to make the user uncomfortable and can maintain a cylindrical shape to the extent that the user can roll when using it by sandwiching it between the back and the guide surface. In addition, because it is a soft material, it is comfortable for the user and does not damage the guide surface. In addition, by applying anti-slip processing such as a molded uneven shape pattern and satin finish on the surface of the cylindrical shape of this instrument, it does not slip against the guide surface during exercise and rotates well in the vertical direction of walls and pillars. The guide surface can be protected from damage caused by friction.

FIG. 2 is an overall view of the cylindrical type of the instrument. Rigid cylindrical core material such as hard vinyl chloride 2 The outer surface of the cylindrical core material is covered with a cushion layer made of a soft non-slip material with appropriate elasticity such as urethane foam. The size of the cylinder is between 8 cm and 20 cm in outer diameter including the cushion layer made of a soft non-slip material on the surface, and the length is about 20 cm to 40 cm. Moderate elasticity is elasticity that is not so stiff that the user is uncomfortable. By covering the outside with a 3-surface non-slip soft material cushion layer, the user is comfortable to use and does not damage the guide surface, and the surface of this instrument's cylindrical 3-surface non-slip soft material cushion layer is molded. Since the uneven shape pattern and anti-slip processing such as satin finish are made, it is possible to protect the guide surface such as walls and pillars from damage due to friction by rotating well without slipping against the guide surface during exercise. can.

FIG. 3 is a perspective view of the initial posture when the cylindrical type of the instrument is used. Since the usage and effects of the cylindrical type of this instrument and the cylindrical type of this instrument are exactly the same, the explanation will be given using the cylindrical type of this instrument as an example, but at the same time, the explanation of the cylindrical type of this instrument shall be exactly the same. .. Place the cylindrical type of this device between your back and the guide surface with the axis of rotation horizontal, and stand with both feet at an appropriate distance from the wall surface so that you lean slightly against the guide surface. The appropriate distance is a position where the position of the toes and knees are approximately the same in the front-back direction when the user is in a squat position during squats. In addition, the exercise load increases as the position of the foot is separated from the guide surface.

FIG. 4 is a side view of the initial posture when the cylindrical type of the instrument is used. The cylindrical type of this device is sandwiched between the user's back and the guide surface with the axis of rotation horizontal, and both feet stand at the above-mentioned appropriate distance from the guide surface. If you stand leaning against the guide surface in this state, you will be in the posture shown in FIG. The position of the cylinder of this device should be placed in the lower part of the back in consideration of the vertical stroke of the squat. Furthermore, when the user begins to crouch (→ moves in the direction of b) → c, the cylindrical shape of this device rolls while being sandwiched between the user's back and the guide surface, and the user can crouch smoothly. .. By exercising while maintaining the state in which the cylindrical shape of this device is sandwiched between the user's back and the guide surface, the user's back surface is kept parallel to the guide surface, and the user's upper body leans forward. Can be prevented from doing so.

FIG. 5 is a side view of a crouching posture when using the cylindrical type of the instrument. It can be seen that the center of gravity of the upper body of A is horizontally far from the position of the knee joint of B because the upper body of the user does not tilt forward. That is, the moment of the load on the quadriceps muscle and the gluteal muscle group becomes large, and a high exercise load can be obtained. Furthermore, when standing up from this posture (moving in the → d direction), the cylindrical type of the instrument rotates in the direction of → e, and rolls while being sandwiched between the user's back and the guide surface to support the user's back. Therefore, the user can stand up smoothly. By exercising while maintaining the state in which the cylindrical shape of this device is sandwiched between the user's back and the guide surface, the user's back surface is kept parallel to the guide surface, and the user's upper body leans forward. Can be prevented from doing so. The bending and stretching motion in which the posture shown in FIG. 4 and the posture shown in FIG. 5 are alternately repeated is a squat motion using the cylindrical type of the instrument.

FIG. 6 is a side view of the squat posture of the squat exercise performed without using the present squat exercise assisting device. The center of gravity of A upper body is close to the position of B knee joint. This is because the upper body must be tilted forward in order to balance it so that it does not fall backward. The horizontal distance between the center of gravity of D upper body and the position of the knee (Fig. 6) is longer than the horizontal distance between the center of gravity of C upper body and the position of the knee (Fig. 5). It can be seen that the moment of is large and a high exercise load can be obtained.
