It is figure (a)-(d) which shows the other form of a supporting member.

  Next, embodiments of the present invention will be described in detail with reference to the drawings. The abdominal muscle assisting tool 1 is used when performing abdominal exercise on the bed. As shown in FIG. 1, the abdominal muscle assisting tool 1 includes a rod-shaped member 2, a support member 3, and a stopper 4. The rod-shaped member 2 is a member for hooking a foot when performing abdominal exercise. The support member 3 is a pair of members that support each end of the rod-shaped member 2.

  The rod-shaped member 2 is a round bar or a pipe having a constant diameter from one end to the other end. The rod-shaped member 2 has a circular outer peripheral surface 21. As for the diameter of the rod-shaped member 2, 30-50 mm is desirable. In this embodiment, the diameter of the rod-shaped member 2 is 35 mm. The length of the rod-shaped member 2 is longer than the width of the bed. For example, when the width of the bed is 95 cm, the length of the rod-like member 2 is desirably 100 to 120 cm. In this embodiment, the rod-shaped member 2 is wooden.

The pair of support members 3 have the same shape or a symmetrical shape. For this reason, only one support member 3 is demonstrated here and the other description is abbreviate | omitted.
The support member 3 has a base portion 31 and side portions 32. The side portion 32 extends upward from the base portion 31. Specifically, the side portion 32 extends from the edge of the base portion 31 in a direction orthogonal to the base portion 31.

  Both the base portion 31 and the side portion 32 are made of a plate having a constant thickness. In this embodiment, the base part 31 and the side part 32 consist of a board with a thickness of 5 mm. Although the material of the base part 31 and the side part 32 is not specifically limited, For example, a vinyl chloride resin (polyvinyl chloride), an acrylic resin, etc. are employable.

  The base portion 31 has a tapered shape in which the dimension in the vertical direction becomes smaller toward the tip at the tip portion 31A far from the side portion 32. Specifically, the distal end portion 31A has an inclined surface that is positioned downward as it goes to the distal end.

  The side portion 32 has a support hole 35 through which the rod-shaped member 2 passes. A plurality of support holes 35 are provided in the side portion 32. The plurality of support holes 35 are located at different heights. The support hole 35 has a shape similar to the outer peripheral shape of the rod-shaped member 2, here, a circular shape. The support hole 35 has a size that allows the rod-like member 2 to pass therethrough.

  At least one support hole 35 is disposed at a position 15 to 40 cm above the base 31. In the present embodiment, the side portion 32 is provided with three support holes 35. The three support holes 35 are lined up and down at intervals (pitch) of 50 mm.

  The stopper 4 is detachably attached to the outer peripheral surface 21 of the rod-like member 2. The stopper 4 is made of an elastic member such as rubber. The stopper 4 has a ring shape. The stopper 4 prevents the rod-like member 2 from coming out of the support hole 35 when attached to the rod-like member 2.

Next, a procedure for attaching / detaching the abdominal muscle assisting tool 1 to / from the bed 5 will be described.
As shown in FIG. 2, the bed 5 includes a bed body 51 and a mattress 52.

  When installing the abdominal muscle assisting tool 1 on the bed 5, first, the pair of support members 3 are arranged on one side and the other side in the width direction of the bed 5. Specifically, the base 31 of the support member 3 is inserted between the bed main body 51 and the mattress 52 and arranged. Next, each end of the rod-shaped member 2 is passed through the support hole 35 of the side portion 32. Finally, the stopper 4 is attached to the outer peripheral surface 21 of the rod-shaped member 2. The stopper 4 may be disposed outside the support member 3 in the width direction of the bed 5 or may be disposed inside. When the stopper 4 is disposed inside the support member 3, the stopper 4 is attached to the rod-shaped member 2 in advance, and the rod-shaped member 2 can be passed through the support hole 35 while the support member 3 is inserted under the mattress 52. That's fine.

  When removing the abdominal muscle assisting tool 1 from the bed 5, first, the stopper 4 is removed from the rod-shaped member 2. Next, the rod-shaped member 2 is pulled out from the support member 3. When removing the rod-shaped member 2, the rod-shaped member 2 may be pulled out without moving the support member 3. Alternatively, the rod-shaped member 2 may be removed from the support member 3 by moving the support member 3 slightly outward in the width direction of the bed 5. Also good. Finally, the support member 3 is pulled out from between the bed main body 51 and the mattress 52.

Next, a method for using the abdominal muscle assisting tool 1 will be described.
As shown in FIG. 3, the user hooks his / her leg on the rod-shaped member 2 of the abdominal muscle assisting tool 1 on the bed 5. The user can easily perform the abdominal muscle exercise by himself / herself without having another person support the foot by hooking his / her foot on the abdominal muscle assisting device 1.

The effect of the abdominal muscle assisting device 1 configured as described above will be described.
If the abdominal muscle assisting device 1 is installed in the bed 5, the abdominal muscles can be easily exercised by one person without having another person support the foot. When the abdominal muscle exercise is not performed, the rod-like member 2 can be easily removed by removing the rod-like member 2 from the support member 3. The removed bar-shaped member 2 can be easily installed again.

  In addition, since the abdominal muscle assisting device 1 does not get in the way even when the abdominal muscle exercise is not performed, the user can sleep while the abdominal muscle assisting device 1 is installed on the bed 5. In this abdominal muscle assisting device 1, it is not necessary to secure a place (space) for placing the abdominal muscle assisting device 1 by using the bed 5. In addition, if it seems that the rod-shaped member 2 is worried when a user sleeps, only the rod-shaped member 2 should just be removed. The rod-shaped member 2 can be easily removed by removing the rod-shaped member 2 from the support member 3.

  In addition, since a plurality of support holes for supporting the rod-shaped member 2 are provided, the height of the rod-shaped member 2 is changed by changing the support hole 35, so that the height can be easily adjusted. In the case of this embodiment, since three support holes 35 are provided, height adjustment in three stages is possible. By adjusting the height to the user's preference, it is possible to perform exercises different from abdominal muscle exercises, for example, back muscle exercises.

  Further, since the base 31 of the support member 3 has a tapered shape at the distal end 31A far from the side 32, the size in the vertical direction becomes smaller toward the distal end, so that the base 31 can be removed from the mattress 52 without lifting the mattress 52. And easy to insert between the bed body 51.

  Moreover, by attaching the stopper 4, it can suppress that the rod-shaped member 2 comes off from the support hole 35, and if the stopper 4 is removed, the rod-shaped member 2 can be removed easily.

  Further, since the base portion 31 and the side portion 32 of the support member 3 are made of a plate having a constant thickness, even if the support member 3 is disposed on the bed 5, it does not disturb the user. For this reason, even if the support member 3 remains arranged on the bed 5, it is difficult for the user to get in the way when sleeping.

  Further, since the rod-shaped member has a constant diameter from one end to the other end, the rod-shaped member can be easily inserted into the support hole.

  As mentioned above, although embodiment of this invention was described, this invention is not limited to the said embodiment. About a concrete structure, it can change suitably in the range which does not deviate from the meaning of this invention.

In the said embodiment, although the side part of the support member extended straightly toward right above from the base, this invention is not limited to this.
For example, as shown in FIG. 4, the support member 103 in the first modification is bent inward in the width direction of the bed 5. Specifically, the side portion 132 has a first portion 133, a second portion 134, and a third portion 135. The first portion 133 extends straight from the base portion 131 toward directly above. The second portion 134 is located on the inner side in the width direction of the bed 5 than the first portion 133. The third portion 135 connects the first portion 133 and the second portion 134. When the support member 103 is disposed on the bed 5, the first portion 133 is located outside the mattress 52 in the width direction of the bed 5. The second portion 134 and the third portion 135 are located above the mattress 52. In the support member 103, the support hole through which the rod-shaped member 102 passes is disposed in the second portion 134.

  In the first modification, even when the bed 5 is adjacent to the wall W of the room, the second portion 134 can be separated from the wall W by a predetermined distance. For this reason, since the rod-shaped member 102 can be sufficiently penetrated through the support hole, the rod-shaped member 102 is not easily detached from the support hole.

Further, as shown in FIG. 5, a cushion 25 may be arranged on the outer peripheral surface 21 of the rod-shaped member 2. The cushion 25 can be attached to and detached from the rod-shaped member 2. As a material of the cushion 25, an elastic material such as sponge or rubber can be employed.
According to this form, when a user hooks a leg on the rod-shaped member 2, it can suppress that a leg becomes painful.

  In the above embodiment, a plurality of support holes are provided on the side, but only one support hole may be provided. For example, as shown in FIG. 6A, one support hole 235 is disposed in the support member 203 of the second modification.

  As shown in FIG. 6B, the support hole 235 includes a first support portion 235A that can support the rod-shaped member, and a second support member that can support the rod-shaped member that is located at a different height from the first support portion 235A. And a support portion 235B. The first support portion 235A and the second support portion 235B have an arc shape with a radius R. The distance L from the center C1 of the first support portion 235A to the center C2 of the second support portion 235B is smaller than the distance 2R that is twice the radius R.

  Also with the support member 203 of the second modification, the height of the rod-shaped member is changed by changing the support portion that supports the rod-shaped member, so that the height can be easily adjusted. Since the distance L between the center of the first support portion 235A and the center of the second support portion 235B is smaller than 2R, the distance between the rod-shaped members is smaller than the case where a plurality of support holes are provided (pitch). The height can be adjusted.

  In the embodiment, the plurality of support holes are arranged in the vertical direction, but the support holes may be arranged in the horizontal direction. For example, as shown to Fig.7 (a), the several support hole 335 of the support member 303 is located in a line with the horizontal direction. In this case, a plurality of rod-shaped members may be inserted into a plurality of support holes arranged in the horizontal direction.

  Further, the plurality of support holes may be arranged at different positions in the vertical direction and the horizontal direction. For example, as illustrated in FIG. 7B, the support member 403 includes a plurality of first support holes 435A arranged in the vertical direction and a plurality of first support holes 435A arranged in different positions in the horizontal direction and arranged in the vertical direction. Second support hole 435B. The second support hole 435B is disposed at a position different from the first support hole 435A in the vertical direction. In this case, the height interval (pitch) can be shortened by arranging the second support holes 435B between the plurality of first support holes 435A in the vertical direction.

In the embodiment, the plurality of support holes are arranged independently, but the support holes may be connected. For example, as shown in FIG. 7C, each support hole 535 of the support member 503 is connected by a connection hole 536. The connecting hole 536 can have a width that allows the rod-shaped member to move.
In this configuration, the rod-shaped member can be supported by each support hole 535, and the rod-shaped member can be moved to the adjacent support hole 535 without removing the rod-shaped member from the support hole 535.

  In the said embodiment, although the base part and side part of the supporting member were the structures which consist of a board, this invention is not limited to this. For example, as shown in FIG.7 (d), it is good also as a structure where the supporting member 603 consists of wires. The base 631 and the side 632 of the support member 603 are made of a single wire. In this configuration, the support member 603 can be reduced in weight. Further, the support member 603 can be made at low cost.

  In the embodiment described above, the rod-shaped member is made of wood and the support member is made of resin, but the materials of the rod-shaped member and the support member are not particularly limited. For example, the rod-shaped member and the support member may be various metals, various plastics, and other materials.

  Each element of each embodiment and each modification mentioned above can be implemented combining arbitrarily.
