Embodiments for Carrying Out the Invention

[0009] Preferred embodiments of the present invention are shown below. [1] The abdominal muscle exercise device of the invention includes a main body part on which the buttocks of a user in a supine position are placed, and a gripping part that is gripped by the user in a supine position. The gripping part is connected to the main body part and can be gripped by the hand of a user in a supine position. According to such a configuration, a user who places their buttocks on the main body part and lies in a supine position, and holds the gripping part with their hand, can effectively exercise the abdominal muscles by maintaining a posture in which the abdominal muscles are loaded during the abdominal muscle exercise of raising the upper body from the supine position. [2] In the abdominal muscle exercise device described in [1] above, a pair of gripping portions may be provided on the left and right, and a space may be provided between the left and right gripping portions to allow the neck of a user in the supine position to be placed. According to such a configuration, in the abdominal muscle exercise of raising the upper body from the supine position, the neck of the user can be avoided from being pushed by the gripping portion, so that the burden on the neck can be reduced. [3] In the abdominal muscle exercise device described in [1] or [2] above, the main body portion has a back placement portion on which the back of the user in the supine position is placed, the gripping portion is connected to the back placement portion, and the back placement portion may be displaceable along the upper body as the upper body of the user in the supine position rises. According to such a configuration, since the user pulls the gripping portion and rises from the supine position together with the back placement portion, it is possible to perform the abdominal muscle exercise in a correct posture with the back rounded. [4] In the abdominal muscle exercise device described in [3] above, the upper surface of the back placement portion may have a top portion and an inclined portion that descends from the top portion toward the side opposite to the hip placement portion. According to such a configuration, the back of the user in the supine position is placed at a high position at the top portion and at a low position toward the shoulder side, so that in the abdominal muscle exercise of raising the upper body from the supine position, the abdominal muscle exercise can be started from a state where the abdominal muscle is more stretched. [5] In the abdominal muscle exercise device described in [3] or [4] above, the back placement portion may have left and right side portions that protrude above the central portion in the left - right direction. According to such a configuration, the body of the user in the supine position is less likely to shift in the left - right direction with respect to the main body portion, so that when maintaining a posture in which a load is applied to the abdominal muscles, the body is less likely to lose balance. [6] In the abdominal muscle exercise device described in any one of [3] to [5] above, the length dimension of the back placement portion is smaller than the length dimension of the user's back, and the end of the back placement portion opposite to the hip placement portion may be located closer to the hip placement portion side than the shoulder of the user in the supine position. According to such a configuration, in the abdominal muscle exercise of raising the upper body from the supine position, the neck of the user can be avoided from being pushed by the main body portion, so that the burden on the neck can be reduced.

[0010] <Example> Hereinafter, an example embodying the present invention will be described in detail with reference to FIGS. 1 to 8. The abdominal muscle exercise device 10 in this example is installed on the floor surface and used when performing abdominal muscle exercises, as shown in FIG. 1. The user lies horizontally on the upper surface of the abdominal muscle exercise device 10 installed on the floor surface in a supine position and performs abdominal muscle exercises. By using the abdominal muscle exercise device 10, the user can effectively exercise the abdominal muscles.

[0011] Hereinafter, in each component, the upper side in the state where the abdominal muscle exercise device 10 is installed on the floor surface is the upper side, the lower side is the lower side, the side where the feet of the user lying on the abdominal muscle exercise device 10 are placed is the front side, the side where the head is placed is the rear side, the right side as viewed from the user lying on the abdominal muscle exercise device 10 is the right side, and the left side is the left side. In each figure, the positive direction of the X-axis is the front direction, the negative direction of the X-axis is the rear direction, the positive direction of the Y-axis is the left direction, the negative direction of the Y-axis is the right direction, the positive direction of the Z-axis is the upper direction, and the negative direction of the Z-axis is the lower direction.

[0012] As shown in FIG. 2, the abdominal muscle exercise device 10 includes a main body portion 20 and a gripping portion 50. The main body portion 20 is formed in a plate shape that is long in the front-rear direction as a whole. The main body portion 20 is made of a material that is difficult to stretch and easy to bend. The gripping portion 50 is connected to the rear end portion of the main body portion 20.

[0013] As shown in FIG. 3, the main body portion 20 has constricted portions 21 on both the left and right sides. As a result, the width of the main body portion 20 in the left-right direction is narrowed at the center in the front-rear direction. The dimension of the main body portion 20 in the left-right direction at the rear end is larger than the dimension of the main body portion 20 in the left-right direction at the front end. The constricted portions 21 allow the left and right side portions 27 described later to follow the body, so that the deviation of the user in the left-right direction can be further reduced.

[0014] As shown in Fig. 4, the main body portion 20 is provided with a hip placement portion 22 on which the buttocks of a user in the supine position are placed, and a back placement portion 23 on which the back of the user in the supine position is placed. The length dimension of the main body portion 20 in the front-rear direction is smaller than the length dimension from the base of the foot to the shoulder based on the standard body type of an adult in Japan. The length dimension of the back placement portion 23 in the front-rear direction is smaller than the back length dimension based on the standard body type of an adult in Japan. The length dimension of the back placement portion 23 in the front-rear direction is larger than the dimension of the hip placement portion 22 in the front-rear direction. The rear end of the main body portion 20 is located in front of the shoulders of the user in the supine position. The lower surface of the main body portion 20 is a flat surface.

[0015] The hip placement portion 22 is plate-shaped. The thickness dimension of the hip placement portion 22 is generally constant throughout. The dimension of the hip placement portion 22 in the left-right direction becomes smaller from the rear side toward the front side (see Fig. 3).

[0016] The back placement portion 23 has a first portion 23F and a second portion 23S. The first portion 23F is the front portion of the back placement portion 23. The constricted portion 21 is provided on the first portion 23F (see Fig. 3). The waist of the user in the supine position is placed on the first portion 23F. The second portion 23S is the rear portion of the back placement portion 23. The portion of the back of the user in the supine position above the waist is placed on the second portion 23S.

[0017] The thickness dimension of the first portion 23F is larger than the thickness dimension of the hip placement portion 22 and the thickness dimension of the second portion 23S. The thickness dimension of the second portion 23S is equivalent to the thickness dimension of the hip placement portion 22. The thickness dimension is the dimension in the vertical direction when the abdominal muscle exercise device 10 is installed on the floor surface.

[0018] The rigidity of the first portion 23F is higher than the rigidity of the hip placement portion 22 and the second portion 23S. The first portion 23F is less likely to bend upward than the hip placement portion 22 and the second portion 23S. The first portion 23F is likely to bend upward starting from the boundary portion 24 with the hip placement portion 22. The second portion 23S is likely to bend upward starting from the boundary portion 25 with the first portion 23F.

[0019] As shown in Fig. 5, the first part 23F has a central part 26 and left and right side parts 27. The left and right side parts 27 protrude upward from the central part 26. The inner surfaces 28 of the left and right side parts 27 slope downward from the apex parts 29 of the side parts 27 toward the central part 26 side. The apex parts 29 of the side parts 27 are the uppermost ends of the side parts 27 in the YZ cross-section. The apex parts 29 of the side parts 27 are located at both left and right ends in the lateral direction of the upper surface of the first part 23F in the YZ cross-section. The outer surface 31 of the first part 23F slopes downward from the apex parts 29 of the side parts 27 toward the center in the lateral direction.

[0020] As shown in Fig. 4, the central part 26 of the first part 23F forms a mountain shape bulging upward in the XZ cross-section. The upper surface of the central part 26 has a top part 32 and front and rear inclined parts 33. The top part 32 is located at the center in the front-rear direction of the first part 23F. The front and rear inclined parts 33 each gently curve and slope downward from the top part 32 toward the front and rear.

[0021] As shown in Fig. 6, the left and right side parts 27 form a mountain shape bulging upward in a side view. The apex parts 29 of the side parts 27 are located slightly above the upper surface of the central part 26 (see Fig. 4). The apex parts 29 of the side parts 27 gently curve and slope downward from the center in the front-rear direction along the upper surface of the central part 26 toward the front and rear. As shown in Fig. 7, when viewed from the front side, the apex parts 29 of the side parts 27 slope so as to be gradually located outward in the lateral direction from the uppermost position downward.

[0022] As shown in Fig. 3, a pair of left and right gripping parts 50 are provided. The left and right gripping parts 50 are gripped by the left and right hands of a user in the supine position (see Fig. 1). Each gripping part 50 has an extension part 51 and a grasping part 52. The extension part 51 is formed of a material that is difficult to stretch and easy to bend. The extension part 51 may be, for example, a rope. One end side in the extending direction of each extension part 51 is connected to the main body part 20. The connecting part 53 between the gripping part 50 and the main body part 20 is provided at the rear end part of the second part 23S.

[0023] The connecting part 53 is arranged at positions on both the left and right sides of the neck of the user in the supine position at the rear end of the second part 23S (see Fig. 1). A space is provided between the left and right extension parts 51 to accommodate the neck of the user in the supine position.

[0024] The gripping part 52 is provided at the end on the side opposite to the connecting part 53 in the extending direction of the extension part 51. As shown in Fig. 1, the gripping part 52 is surrounded by the palm and fingers of the user's hand. The shape of the gripping part 52 is circular in a cross-section perpendicular to the extending direction of the extension part 51 (see Fig. 8). The gripping part 52 is easy to adhere to the palm of the user's hand.

[0025] Next, an example of a method of performing an abdominal muscle exercise using the abdominal muscle exercise device 10 will be described. As shown in Fig. 4, the user installs the abdominal muscle exercise device 10 on the floor surface, places the buttocks on the buttock placement part 22, and lies on the side in a supine position. By placing the buttocks on the buttock placement part 22, it is possible to prevent the buttocks from hurting. The waist of the user in the supine position is arranged above the first part 23F. The back of the user in the supine position is arranged at a position where the shoulders are lower than the waist. The neck of the user in the supine position is arranged between the left and right extension parts 51.

[0026] As shown in Fig. 1, the user in the supine position grabs the left and right gripping parts 52 with both left and right hands and bends the arms. The upper arms of the user extend forward from the shoulders, and the forearms extend upward from the elbows. The user arranges both left and right hands behind the shoulders.

[0027] Next, the user starts the abdominal muscle exercise. As shown in Fig. 4, in the supine position, the upper body of the user is in a state of descending from the waist towards the shoulders. As a result, the stretching of the abdominal muscles when raising the upper body from the supine position is greater than when the upper body is horizontal from the waist to the shoulders in the supine position. As shown in Fig. 1, the user raises the upper body while holding the gripping part 50 and pulling it towards the front side of the user. By using the abdominal muscle exercise device 10, the user can maintain a posture in which a load is applied to the abdominal muscles.

[0028] During abdominal muscle exercise, as shown in Fig. 1, the left and right extensions 51 extend forward from the user's shoulders along the back of the user's shoulders and on both left and right sides of the user's neck. When the user tries to raise the upper body, the main body 20 bends at the boundary parts 24, 25, and the back rest part 23 tries to be displaced upward together with the upper body so as to support the back of the supine user. Since the main body 20 is pressed against the floor surface by the user's buttocks, the displacement between the main body 20 and the user's body is prevented. Since the back rest part 23 is arranged below the user's upper body with its vertical displacement restricted by the buttock rest part 22, there is a difference between the displacement amount of the back rest part 23 and the displacement amount of the user's upper body. Therefore, when the user's upper body is lifted to an angle at which a high load is applied to the abdominal muscles, it becomes difficult for the user to lift the upper body further. As a result, the user can maintain the upper body at an angle at which a high load is applied to the abdominal muscles. Even if the user's upper body is only slightly lifted from the supine position, isometric contraction occurs in the abdominal muscles, so the user can effectively exercise the abdominal muscles.

[0029] The user can exercise the body by lifting the upper body to an angle at which a high load is applied to the abdominal muscles and maintaining the upper body as it is, and by continuously repeating the exercise of lifting the upper body to an angle at which a high load is applied to the abdominal muscles. Since the user's body is made less likely to be displaced in the left - right direction by the left and right side parts 27, the user can less easily lose balance when maintaining the posture of abdominal muscle exercise. Also, the user may hold one of the left and right gripping parts 50 with one hand and perform abdominal muscle exercise. In this case, the user can stimulate not only the rectus abdominis but also the obliquus abdominis.

[0030] Next, the operations and effects of the embodiment configured as described above will be explained. The abdominal muscle exercise device 10 includes a main body portion 20 and a gripping portion 50. The main body portion 20 has a lying position user's buttocks placed thereon. The gripping portion 50 is gripped by a lying position user. The gripping portion 50 is connected to the main body portion 20 and can be gripped by the hands of a lying position user. According to this configuration, a user who places their buttocks on the main body portion 20 and assumes a lying position and grips the gripping portion 50 with both left and right hands can effectively exercise the abdominal muscles by maintaining a posture in which a load is applied to the abdominal muscles.

[0031] A pair of gripping portions 50 are provided on the left and right. There is an interval between the left and right gripping portions 50 where a lying position user's neck can be placed. According to this configuration, in an abdominal muscle exercise of raising the upper body from a lying position, the user's neck can be prevented from being pushed by the gripping portion 50, so the burden on the neck can be reduced.

[0032] The main body portion 20 has a back placement portion 23 on which a lying position user's back is placed. The gripping portion 50 is connected to the back placement portion 23. The back placement portion 23 is displaceable along the upper body as the upper body of a lying position user rises. According to this configuration, since the user pulls the gripping portion 50 and rises from a lying position together with the back placement portion 23, it is possible to perform an abdominal muscle exercise in a correct posture with the back rounded.

[0033] The upper surface of the back placement portion 23 has a top portion 32 and an inclined portion 33 that slopes downward from the top portion 32 toward the rear. According to this configuration, a lying position user's back is placed at a high position at the top portion 32 and at a low position toward the shoulder side, so in an abdominal muscle exercise of raising the upper body from a lying position, the abdominal muscle exercise can be started from a state where the abdominal muscles are more stretched.

[0034] The back placement portion 23 has left and right side portions 27 that protrude above the central portion 26. According to this configuration, a lying position user's body is less likely to shift in the left - right direction with respect to the main body portion 20, so the body can be made less likely to shift left and right when maintaining a posture in which a load is applied to the abdominal muscles.

[0035] The length dimension of the back placement part 23 is smaller than the length dimension of the user's back. The rear end of the back placement part 23 is located in front of the shoulders of the user in the supine position. According to this configuration, in the sit-up exercise of raising the upper body from the supine position, the user's neck can be avoided from being pushed by the main body part 20, so the burden on the neck can be reduced.
