The swing board B of the present invention comprises a board body 10.

The present invention can be used as a surfboard or the like for sports or entertainment by floating the swing board B on the sea in this form.

A separately formed auxiliary rocking plate 20 can be attached to the outer bottom surface of the rocking board B.

That is, the auxiliary rocking plate 20 has an upper surface formed on a flat surface so that it can be attached to the virtual center of gravity 11 of the board body 10, and can be attached to the outer bottom surface of the rocking board B. The bottom surface central portion 22 is formed on a flat surface 23 having a smaller area than the upper surface flat surface 21, and an inclined surface 27 is formed from the central flat surface 25 of the bottom surface 24 toward the bottom surface periphery 26.

Specifically, as shown in FIGS. 1 and 2, the auxiliary rocking plate 20 has an upper surface flat surface 21 having no unevenness. The lower surface of the auxiliary rocking plate 20 is cut horizontally on the way to the top of the octagonal pyramid to form a flat surface 23 having a small area.

The small-area flat surface 23 has a substantially octagonal arc that is smoothly convex toward the bottom surface peripheral 26 (periphery of the upper surface flat surface 21) so as to be connected to each side of the upper surface flat surface 21. The inclined surface 27 of the shape is formed.
The flat surface 23 having a small area may be configured to be smaller than the area of the flat surface 21 on the upper surface, and when training by boarding the board body 10 described later according to the area of the flat surface 23 having a small area. The degree of swing of the board body 10 can be changed. At this time, the smaller the area of the flat surface 23 having a small area, the smaller the installation area of the auxiliary rocking plate 20 with the ground. That is, as the flat surface 23 having a small area becomes smaller, the auxiliary rocking plate 20 easily swings, and it becomes difficult to balance when training using the auxiliary rocking plate 20.
On the contrary, the larger the area of the flat surface 23 having a small area, the larger the installation area of the auxiliary rocking plate 20 with the ground. That is, the large flat surface 23 having a small area causes the auxiliary rocking plate 20 to be difficult to swing, and it becomes easy to balance when training using the auxiliary rocking plate 20.
By changing the area of the flat surface 23 having a small area in this way, it is possible to generate a swinging state tailored to each individual.
The form of the auxiliary rocking plate 20 may be such that the flat surface 23 having a small area is smaller than the area of the flat surface 21 on the upper surface, and is a truncated cone having a substantially circular shape in a plan view or a truncated cone having a substantially triangular shape in a plan view. It may be formed.

Further, as shown in FIG. 7, a flat portion 12 having a predetermined size is formed on the bottom surface 16 (bottom surface of the virtual center of gravity portion) of the virtual center of gravity portion 11 in the board body 10 of the separately prepared rocking board B, and is flat. An inclined bottom surface 15 is formed from the portion peripheral edge 13 toward the peripheral edge 14 of the board body.

Specifically, the swing board B is composed of a board body 10 having a substantially rectangular shape in a plan view.

As shown in FIG. 3, the board body 10 has an upper surface formed on a flat surface and a virtual center of gravity portion 11 formed at a substantially central portion in a plan view.

A substantially octagonal flat portion 12 is provided on a substantially central portion on the bottom surface side of the board body 10, that is, on the bottom surface 16 of the virtual center of gravity portion 11.

The flat portion 12 is provided with an inclined bottom surface 15 in an arc shape that is convex from each side of the octagonal shape, that is, from the peripheral edge 13 of the flat portion toward the peripheral edge 14 of the board body (see FIG. 7).

By configuring the bottom surface 16 of the virtual center of gravity 11 of the board body 10 of the rocking board B as described above, the same swinging function as the auxiliary rocking plate 20 described above is possessed.

Further, a plurality of fixing holes 31, 31, ... For fixing the tube 30 made of an elastic body for training are bored in the peripheral edge 14 of the board body. The fixing holes 31, 31, ... Are formed near the front and rear ends 10a and 10b of the board body 10 and closer to the center of the board body 10 than the front and rear ends 10a and 10b.

The fixing holes 31, 31, ... Are bored in a substantially circular shape in a plan view, and a fixing rod 32 is arranged inside the fixing hole 31 in the radial direction of the fixing hole 31. As shown in FIGS. 5, 6 (a) and 6 (b), the fixing rod 32 is a metal rod formed of a solid and columnar metal, and both ends thereof are inserted into the board body. Therefore, the tube 30 fixed to the fixing rod 32 does not have a possibility of hindering the movement without shifting the position of the tube 30 even if the user performs a vigorous exercise using the swing board B.

In addition, the board body 10 is composed of a foam (for example, urethane foam, styrofoam, etc.) containing a large amount of air as the main material, and the surface thereof is further surrounded by glass fiber (FRP). It is formed by coating with a water-repellent paint. Therefore, the board body 10 can float not only on the ground surface but also on the water surface to generate an appropriate training effect as in the ground surface. The material of the board body may be any material as long as it can float on water.

Further, as shown in FIG. 4, a fin installation portion 19 is bored at substantially the center in the width direction of the inclined bottom surface 15 on the rear end portion 10b side of the board body 10. The fin installation portion 19 is provided with an elongated rectangular hole in the front-rear direction so that fins used in a surfing board or the like can be installed. By providing the fin installation portion 19 in this way, when the swing board B is used on the water surface, especially when the user gets on the swing board B and swings to the left or right, the fin becomes a resistance and swings. The risk of the board B rotating on the water surface can be reduced, and an appropriate training effect can be produced.

Further, an auxiliary rocking plate 20 separately prepared can be provided so as to project from the bottom surface of the board body 10 of the rocking board B.

That is, the rocking board B forms an auxiliary rocking plate 20 having a substantially flat upper surface as shown in FIG. 7 by forming a flat portion 12 having a substantially flat surface 16 on the bottom surface of the board body 10. Can be pasted. As for the means for attaching the auxiliary rocking plate 20 to the board body 10, what kind of attachment is used as long as the auxiliary rocking plate 20 does not come off from the board body 10 when training using the rocking board B. It may be worn by means of wearing, for example, it is attached with an adhesive tape or a hook-and-loop fastener.

The board body 10 of the rocking board B in a state where the auxiliary rocking plate 20 is not attached has a function of a surfing board or windsurfing capable of sliding on the wave surface on the sea, and is used as it is as a surfing board or windsurfing. You can also do it.

Further, as shown in FIGS. 3 and 5, a cross-shaped walking guide band 18 having a substantially central portion of the virtual center of gravity 11 as a cross-shaped crossing portion 17 is displayed on the upper surface of the board body 10 of the rocking board B. Therefore, when boarding the board main body 10 and moving to a predetermined balance point, if the player moves along the cross-shaped walking guide band 18, the virtual center of gravity portion 11 can be accurately walked and moved. Therefore, it is possible to prevent an accident in which the board body 10 inadvertently tilts and falls while the user of the board body 10 is moving.

Further, on the upper surface of the board body 10 of the swing board B, a balance portion indicating a portion where the user performing training can easily maintain the balance, that is, a line 11a having a substantially circular shape in a plan view indicating the virtual center of gravity 11 is displayed. ing.
The form of the line 11a showing the virtual center of gravity portion 11 is not limited to the circular shape, and any form may be used as long as the virtual center of gravity portion 11 of the swing board B such as a rectangular shape in a plan view or a floral pattern can be shown. ..

A procedure for performing training using the swing board B configured in this way will be described.

As shown in FIG. 8, the board body 10 is formed from the guides 18a, 18a, 18b, 18b of any of the long side guides 18a, 18a and the short side guides 18b, 18b of the cross-shaped walking guide band 18 displayed on the upper surface of the board body 10. Place your foot on the top of the obi. At this time, the balance during walking can be properly maintained by placing all the soles of the feet within the width of the cross-shaped walking guide band 18.

As shown in FIG. 9, the user walks into the line 11a indicating the virtual center of gravity 11 along the cross-shaped walking guide band 18 of the long side guide 18a.

As shown in FIG. 9, after invading the line 11a, the user puts the sole arch lid (arch of the foot) of the sole of the foot on the short side guides 18b, 18b or the long side guides 18a, 18a of the cross-shaped walking guide band 18. Place on. At this time, by opening the legs to the left and right so as to straddle the crossing portion 17, even a person who has never used the swing board B can easily balance.

As shown in FIG. 10, the user who is in a standing posture in the virtual center of gravity 11 opens his / her legs to the line 11a indicating the virtual center of gravity 11 on the upper surface of the board body 10, and puts the sole of the foot on the line 11a. Place.

As shown in FIGS. 11A and 11B, the user bends his knees on the line 11a and lowers his hips to keep the center of gravity low. In this state, the board body 10 can be swung in the front-rear direction or the left-right direction by alternately applying force to the left and right legs. At this time, since a flat surface is formed on the flat portion 12 of the board body 10 or the flat surface 23 having a small area of the auxiliary rocking plate 20, the rocking board B is flat when it swings back and forth and left and right. The rocking state of the board body 10 is temporarily discontinuous at the peripheral edge 13 of the portion or around the bottom surface 26 of the auxiliary rocking plate 20, and the user feels uncomfortable. Therefore, the user of the board body 10 can imagine the displacement form of the board body 10 without shifting the line of sight downward, and can imagine how much force the board body 10 can be pressed to maintain the balance. As a result, the user can continuously exercise.

After the training is completed using the swing board B, the user can use the short side guide 18b of the cross-shaped walking guide band 18 from the line 11a of the virtual center of gravity 11 in the reverse of the procedure for boarding the board body 10. It is possible to get off the board body 10 via the guides 18a, 18a, 18b, 18b of 18b and any of the long side guides 18a, 18a.

For example, as shown in FIG. 12, the user takes a standing posture on the virtual center of gravity 11 in the line 11a, grips one end of the tube 30 fixed to the fixing holes 31, 31, ,, and the swing board. While performing balance training in B, upper body training can be performed at the same time as lower body balance training using the tube 30.

As described above, the swing board B can not only perform balance training when the board body 10 is used alone, but also attach the auxiliary swing plate 20 to the bottom surface 16 of the virtual center of gravity portion 11 of the board body 10. By doing so, the degree of balance training can be changed according to the skill level of the user. Further, by making the board body 10 made of a material that can float on the water surface and further making it so that fins can be installed on the back surface of the board body 10, the swing board B can generate the same training effect as the ground surface on the water. .. Further, in addition to the above contents, by providing a fixing rod 32 on the upper surface of the board body 10 so that the tube 30 can be used, the swing board B is subjected to balance training of the lower body by the board body 10 and at the same time. There is an effect that the upper body can be trained by using the elastic tube 30.

Further, the form of the swing board B is not limited to the substantially octagonal shape in the plan view described in the present embodiment, and any form may be used as long as an appropriate training effect can be realized. It may be formed in a circular shape.
