Embodiments of the present invention will be described below based on the drawings.

FIG. 1 is a diagram showing an example of the appearance of a training aid 1. As shown in FIG.

The training aid 1 includes a main body 10 and a receiver 20. The main body portion 10 is a member that the user's body comes into contact with during training. Although the material constituting the main body part 10 is not limited, it is preferable that the main body part 10 is made of a strong material that can bear the weight of the user. The main body portion 10 can be made of wood or resin, for example. Note that the main body portion of the main body 10 excluding the protrusions 112 and magnets 113, which will be described later, may be formed by combining different materials.

At least a part of the support tool 20 is made of an elastic body. The training aid 1 is used by placing the main body 10 on the support tool 20. The training aid 1 may be used by placing the main body 10 directly on a floor or a table without using the support tool 20. Also, a non-slip sheet (not shown) may be provided separately under the support tool 20.

The main body 10 has an upper surface 11 and a bottom 12. The upper surface 11 is located on the upper surface of the main body 10, and at least a portion of the upper surface 11 is flat. The bottom 12 is formed at the lower part of the main body 10 and bulges downward.

Although the details will be described later, the training aid 1 in this embodiment has a first usage mode in which it is placed with the top surface portion 11 facing upward, and a first usage mode in which it is used with the bottom portion 12 facing upward and the top surface portion 11 is placed on the bottom side. A second usage mode in which the device is placed and used in such a way as to support the user's training. Hereinafter, explanation will be given based on the installation direction of the training aid 1 in the first usage mode.

FIG. 2 is a diagram for explaining the movement of the training aid 1 in the first usage mode. FIG. 2(A) is an example of a front sectional view of the training aid 1, FIG. 2(B) is an example of a left side sectional view of the training aid 1, and FIG. 2(C) is an example of the left side sectional view of the training aid 1. It is an example of the top view of an instrument. 2(A) shows an example of the AA' cross section in FIG. 3(B), which will be described later, and FIG. 2(B) shows an example of the BB' cross section in FIG. 3(A). There is. In the following description, the Y-Y axis direction on the paper surface of FIG. 2(A) is assumed to be the left-right direction, the Z-Z-axis direction is the vertical direction, and the XX-axis direction on the paper surface of FIG. 2(B) is the front-rear direction.

FIG. 3 is a diagram showing an example of the appearance of the main body portion 10 of the training aid 1. As shown in FIG. 3(A) is a front view of the main body 10, FIG. 3(B) is a side view of the main body 10, and FIG. 3(C) is a plan view of the main body 10.

As shown in FIGS. 2(A) and 3(A), the surface of the bottom portion 12 is smoothly curved from one end to the other end in the left-right direction of the upper surface portion 11 so as to form a substantially circular arc shape when viewed from the front. do. Further, as shown in FIGS. 2(B) and 3(B), the surface of the bottom portion 12 is curved downward so that one end and the other end of the upper surface portion 11 in the front and back direction are smoothly continuous when viewed from the side. It is formed by In addition, the surface of the bottom part 12 may be formed so that the outline connecting one end and the other end of the upper surface part 11 in the front-rear direction has a substantially arc shape in a side view as well as in a front view.

In the front views shown in FIGS. 2(A) and 3(A), a part of the body is placed on each of the placing portions 111 (described later) provided at symmetrical positions on the upper surface portion 11 of the main body portion 10. Place it in place and apply downward pressure alternately on the left and right sides. The main body portion 10 contacts the mounting surface of the receiver 20 and the like at the apex G, which is the point where a perpendicular line passing through the center of gravity C contacts the surface of the bottom portion 12 . The main body part 10 swings in a roll direction centering on the front-rear direction (X-axis direction) by applying pressure from above alternately on the left and right sides. Additionally, at this time, the main body portion 10 swings along the surface of the bottom portion 12 including the apex G so as to rotate around the X-axis.

In the side views shown in FIGS. 2(B) and 3(B), a part of the body is placed on the upper surface 11 of the main body 10, pressure is applied from above to the front of the upper surface 11, and then the rear Apply pressure from above. That is, pressure is applied downward alternately back and forth. Thereby, the main body portion 10 swings in the pitch direction with the left-right direction (Y-axis direction) as the axis center. Additionally, at this time, the main body portion 10 swings along the surface of the bottom portion 12 including the apex G so as to rotate around the Y axis.

In addition, in the plan views shown in FIGS. 2(C) and 3(C), a part of the body is placed on each of the placing parts 111, and the part placed on one is moved forward and the part placed on the other is moved. Move the placed part backwards. Next, the portion moved forward is moved backward, and the portion moved backward is moved forward. In this way, the parts of the body placed on each of the placing parts 111 are moved back and forth alternately. Thereby, the main body portion 10 swings in the yaw direction with the vertical direction (Z-axis direction) as the axis center. In addition, at this time, the main body portion 10 rotates around the Z-axis with a perpendicular line passing through the center of gravity C and the apex G as the central axis.

When a conventional stepping device allows rocking in one direction, such as a roll direction, and does not allow rocking in other directions, the user T moves his or her body in accordance with the rocking motion allowed by the device. In some cases, unreasonable movements are forced. The training aid 1 in this embodiment swings the main body 10 in a roll direction centered on the front-back direction, and in a pitch direction centered on the left-right direction and in a yaw direction centered on the vertical direction. The bottom portion 12 is curved so that it can be swung at the same time. With this configuration, the main body 10 moves to follow the smooth movements of the user T's joints, so the user T is not forced to make forced movements, and training that is more suited to the characteristics and movements of the user's body can be performed. Can be done.

As shown in FIGS. 3(B) and 3(C), the length of the main body 10 in the left-right direction is the width W, and the length of the main body part 10 in the vertical direction excluding protrusions 112 and magnets 113, which will be described later. The length is defined as the height H, and the length of the longest central portion of the length in the front-rear direction is defined as the depth D1. As shown in FIG. 3(C), the upper surface portion 11 is formed so that the width W is longer than the depth D1 in plan view.

If the ratio of the width W to the depth D1 is small, that is, if the difference between the width W and the depth D1 is small, the swing direction will not be stable when applying pressure to the top surface part 11 to swing the main body part 10, and the user may There is a possibility that you will not be able to train in accordance with your intentions. In particular, as shown in FIGS. 2(A) and 3(A), even when it is desired to swing the main body 10 in the left-right direction (in the roll direction), the main body 10 may move in an unintended direction. Sexuality increases. Furthermore, if the ratio of the width W to the depth D1 is large, the posture of the main body 10 during use will not be stable, and for example, as shown in FIGS. 2(B) and 3(B), the main body 10 may be When swinging (in the pitch direction), there is a possibility that the main body 10 may fall forward or backward.

The ratio of the width W to the depth D1 is preferably 2.5 or more and less than 4, more preferably 2.8 or more and less than 3.5, and still more preferably 3 or more and less than 3.3. Thereby, when applying loads alternately in the left and right directions, the main body portion 10 can be more stably swung left and right.

In addition, in this embodiment, the main body 10 is formed such that the width W is longer than the height H when viewed from the front. If the ratio of the width W to the height H is small, i.e., if the difference between the height H and the width W is small, the posture of the main body 10 may not be stable when the upper surface 11 is pressed to rock the main body 10, and the main body 10 may fall in the front-rear direction. On the other hand, if the ratio of the width W to the height H is large, the rocking of the main body 10 may be restricted even when pressure is applied to the upper surface 11, and the movement may not be as intended by the user.

The ratio of the width W to the height H is preferably 3.5 or more and less than 5.2, more preferably 3.9 or more and less than 4.8, and even more preferably 4.1 or more and less than 4.6. This allows the main body 10 to be swung more stably in the left-right and front-back directions.

Further, as shown in FIG. 3C, the upper surface portion 11 has a shape that swells from both ends in the left-right direction toward the center in a plan view. In other words, the main body 10 has a shape in which a part of a rugby ball is separated by a plane parallel to a line connecting each vertex. In this embodiment, opposing sides in the longitudinal direction of the upper surface part 11 can be formed so as not to have any parallel parts. By forming the body so that it does not have any parallel parts in the left-right direction, the center of gravity C is stabilized at the center, and the left-right balance is achieved. It can be used stably with good movement when swinging from side to side. Further, as shown in FIGS. 2(C) and 3(C), even when the main body portion 10 is rotated about the vertical direction when viewed from above, it can be used more stably.

Further, the surface of the bottom portion 12 does not have a flat surface in a portion including the vertex G located directly below the center of gravity C. That is, the surface of the bottom portion 12 does not have a planar shape including the vertex G. Thereby, when the main body part 10 swings in the left-right direction or the front-back direction, it can move smoothly.

In addition, by forming the surface of the bottom portion 12 into a substantially arc shape when viewed from the front and curved so as to be smoothly continuous when viewed from the side, the connection between the receiving tool 20 or the mounting surface and the bottom portion 12 of the main body portion 10 is improved. The vertices G, which are the points of contact, can be concentrated near the center of gravity C in a top view. Thereby, when the main body part 10 is rocked in the left-right direction and the front-back direction, it can be rocked more stably. Furthermore, compared to conventional training aids in which the front and rear surfaces of the bottom portion 12 are parallel to each other near the floor, the training aid 1 according to the present embodiment is stable without causing the body portion 10 to fall back and forth. can be used.

Further, as shown in FIG. 3C, both ends of the upper surface portion 11 in the left and right direction are parallel when viewed from above. The ratio of the depth D1 to the length D2 of the straight line portion of both ends in the left and right direction is preferably 2.8 or more and less than 4.2, more preferably 3 or more and less than 3.9. , more preferably 3.3 or more and less than 3.7. Forming the device so that both ends in the left and right direction are parallel produces a psychological effect in which a part of the body is placed parallel to the both ends during use.

The upper surface portion 11 has a pair of placement portions 111 on which parts of the user's body are placed at symmetrical positions. As shown in FIG. 3A, the mounting portion 111 is formed to be depressed downward from the top surface of the upper surface portion 11. As shown in FIG. In the first usage mode, the user places a part of his body on each of the placing parts 111, and swings the main body part 10 by applying pressure from above alternately from left to right or front to back. By forming the placing portion 111 in a recessed manner, it is possible to clearly indicate the location on which the body is placed.

In addition, each of the mounting parts 111 can be formed so that the front and back are open, and the left and right edges are parallel to each other. More specifically, the mounting portion 111 can be formed such that the edge of the depression is a straight line parallel to both ends of the upper surface portion 11 in the left-right direction. As a result, the user is psychologically guided to bring his/her body into contact with the upper surface part 11 so as to be parallel to the straight line of the edge portion of the placing part 111 . That is, this has the effect of preventing the body from being placed on the upper surface part 11 from an unstable direction and encouraging the user to use it more safely.

Each of the mounting parts 111 has a plurality of projections 112 that project upward. Although the number of protrusions 112 is not limited, it is desirable to provide four to five protrusions 112 for one mounting portion 111. Although the material of the protrusions 112 is not limited, in this embodiment, the protrusions 112 are produced by mixing ceramic with fine ore powder and sintering the mixture. In this embodiment, at least one of tourmaline, black silica, germanium, terra ore, or radium is used as the fine ore powder.

Tourmaline is thought to become electrically charged when heated, so by using tourmaline for the protrusions 112, a weak current flows through the body due to frictional heat or body temperature, which can be expected to promote blood circulation.

Black silica is a natural ore containing graphite and silica. Since black silica has a high far-infrared effect, it can be expected to contribute to promoting blood circulation. Germanium is expected to have the effect of promoting blood flow, and is thought to have the effect of relieving stiffness. Terra ore is an artificial ore produced by crystallizing silicon, and is thought to generate electromagnetic waves called terahertz waves. Terahertz waves have high thermal conductivity and can be expected to stimulate a rise in body temperature through vibration and energize the body.

Additionally, radium is thought to have the ability to generate small amounts of radiation to stimulate the body and activate cells. The use of radium is expected to increase immunity. In this embodiment, Badgastein ore, which is known to emit radium, can be used as the material for the projections 112. In particular, in usage situations where the extremities of the body, such as the fingers and toes, are placed on the mounting portion 111, by using Badgastein ore for the protrusions 112, blood circulation at the extremities is promoted due to the action of radium, which has a cooling effect. can be expected.

By forming the protrusions 112 on the placement portion 111, it is possible to clearly indicate to the user the contact points on the body, and to encourage safe use. In addition, by forming the protrusions 112, it is possible to prevent the contact points on the body and the training aid 1 from slipping and becoming misaligned.

The upper surface portion 11 has a magnet 113. One or more magnets 113 are installed between the pair of placement parts 111. The magnet 113 is expected to generate lines of magnetic force and promote blood circulation at the contact point. Further, by bringing the user's body into contact with the magnet 113, static electricity accumulated in the body can be released.

As described above, according to the training aid 1 of this embodiment, by swinging to follow the movement of the user T's body, it is possible to support appropriate training. By forming the width W to be larger than the depth D1, the main body 10 can not only be swung in the direction desired by the user T, but also be stored more compactly when not in use. .

Further, the surface of the bottom portion 12 is smoothly curved from one end of the upper surface portion 11 in the left-right direction to the other end so as to form a substantially circular arc shape when viewed from the front, and one end of the upper surface portion in the front-back direction when viewed from the side. and the other end are curved downward so that they are smoothly continuous. As a result, compared to, for example, a training device that is used by placing a footboard with a length exceeding the diameter of the cylinder on a cylinder lying on its side, the movement of the footboard is not obstructed when applying pressure to the upper surface 11, so it is smoother. It becomes a movement.

FIG. 4 is a diagram showing an example of how to use the training aid 1 in the first usage mode. FIG. 4(A) is a plan view of usage example 1, and FIG. 4(B) is a plan view showing a state in which the main body portion 10 is rotated in usage example 1.

As shown in Fig. 4(A), a usage method in which the calf is placed sideways on each of the placement sections 111 is assumed to be usage example 1. After that, for example, the waist is twisted and the foot is kicked downward in the plane of the paper in Fig. 4(B). This movement causes the main body section 10 to rotate around the Z axis, i.e., in the yaw direction.

Further, the user T may continue to move the left and right calves alternately up and down in the direction of gravity. That is, the mounting portion 111 of the training aid 1 is pressurized from above alternately on the left and right sides. As a result, the main body portion 10 swings around the X axis, that is, rotates in the roll direction. In addition, by placing the main body part 10 on the receiver 20, the receiver 20 supports the bottom part 12 when the main body part 10 swings in the left-right direction and the front-back direction, so that it can be used stably. can. Additionally, by using the receiver 20, it is possible to prevent the ground surface of a floor or table top from rubbing against the bottom 12 and being scratched.

FIG. 5 is a diagram (part 1) showing another example of how to use the training aid 1 in the first usage mode. FIG. 5(A) is a front view of usage example 2, and FIG. 5(B) is a side view of usage example 3.

As shown in FIG. 5(A), usage example 2 is a usage method in which the user T lies down and places his/her ankles on the placement part 111. The user T places the vicinity of the ankle on each placing portion 111 from the side. Thereafter, by applying pressure from above to the upper surface portion 11 alternately on the left and right sides, the main body portion 10 swings so as to rotate around the X-axis.

5B, a usage method in which a user T places the sole of his/her foot on the placement portion 111 will be referred to as Usage Example 3. The user T applies pressure from above to the upper surface portion 11 alternately back and forth, thereby rocking the main body portion 10 so that it rotates around the Y axis.

FIG. 6 is a diagram (part 2) showing another example of how to use the training aid 1 in the first usage mode. In usage example 3, when the user T places the sole of the foot on the placing part 111 and applies pressure alternately on the left and right sides, the main body part 10 swings around the X-axis. Furthermore, when the user T moves his or her feet alternately back and forth, the main body 10 rotates around the Z-axis.

FIG. 7 is a diagram (part 3) showing another example of how to use the training aid 1 in the first usage mode. As shown in this figure, a usage example 4 is a usage method in which the user T places his wrist, elbow, or upper arm on the placement part 111. When the user T moves the mounting portion alternately back and forth, the main body 10 rotates around the Z axis. Further, when the user T applies pressure from above alternately in the front and back, the main body 10 swings to rotate around the Y-axis. Further, when the user T applies pressure from above alternately on the left and right sides, the main body 10 swings to rotate around the X-axis.

In addition, the configuration of the placing part 111 and the shape of the upper surface part 11 in this embodiment guide the user T to place his or her body on the placing part 111, so that the user T is guided to place his or her body on the placing part 111, so that the user T may not touch the body in an unstable position. Accidents caused by this can be prevented, and the training aid 1 can be used more safely.

FIG. 8 is a diagram showing an example of the appearance of the training aid 1 in the second usage mode. FIG. 8(A) is a diagram showing an example of the appearance of the main body part 10 in the second embodiment, and FIG. 8(B) is a diagram showing an example of how to use the training aid 1 in the second usage mode. be.

8, in the second usage mode, the main body 10 is used with the upper surface 11 facing downward. Since at least a part of the upper surface 11 is flat, when the upper surface 11 is placed facing downward, the main body 10 is stably installed without rocking.

As shown in FIG. 8(B), the user T places a desired part of the body on the bottom 12 of the main body 10 that protrudes upward, and applies a load by relaxing the body. Since the bottom part 12 is raised so as to be smoothly continuous from the left and right directions and the front and back directions of the upper surface part 11, it is possible to obtain the desired massage effect without putting a burden on the body, such as when the corners of the training aid 1 hit the body. can. For example, as shown in FIG. 8(B), by placing the main body part 10 under the waist and lying on your back, you can stretch your back muscles.

Further, the surface of the bottom portion 12 is curved from one end of the upper surface portion 11 in the left-right direction to the other end to form a substantially circular arc shape when viewed from the front, and is curved from one end of the upper surface portion 11 in the front-back direction to the other end when viewed from the side. It is curved so that the ends are smoothly continuous. With this configuration, the curved portion comes into contact with the body in a manner that fits the body, providing a comfortable feeling of use.

In addition, since the width W of the upper surface portion 11 is longer than the depth D1, that is, the main body portion 10 is formed to have an elongated shape as a whole, in the second usage mode, Suitable for contacting parts where there is a long and narrow gap between the surface and the surface.

In the second usage mode as well, the receiver 20 may be installed under the main body 10, or the main body 10 may be placed directly on the floor or tabletop without using the receiver 20.

Here, an example of a manufacturing method for the main body 10 will be described. For example, the main body 10 is manufactured from wood such as Japanese cypress. To form the main body 10 from three layers of wood, each piece of wood is cut into the shape of the main body 10, and the cut surfaces are glued together to obtain the main body 10 in its rough shape. The cut surfaces to be glued together are approximately flat. The wood located on the top surface 11 is provided with recesses that form the mounting portion 111 at symmetrical positions.

Thereafter, the surface of the main body part 10 is prepared with a file to give it a smooth shape. The position where the protrusion 112 is to be formed is determined, and a recess into which the separately prepared protrusion 112 is to be fitted is formed in the upper surface part 11. Thereafter, the protrusion 112 is fitted into the recess and bonded. Further, the position where the magnet 113 is to be formed between each of the mounting parts 111 is determined, a recessed part is formed in the same manner as the formation of the protrusion 112, and the magnet 113 is fitted and bonded.

The method of forming the main body part 10 is not limited, but considering the usage form in which pressure is applied from above to the top part 11 or the bottom part 12, the top part 11 is formed from a single material rather than an assembly of a plurality of materials. It is preferable that it be formed by processing a material. By stacking wood in layers as in this example, it is possible to create a training aid 1 that is resistant to pressure from above.

Although the embodiments according to the present invention have been described above, the present invention is not limited to one example of the above-described embodiments, and includes various modifications. For example, the example of the embodiment described above has been described in detail to make the present invention easier to understand, and the present invention is not limited to having all the configurations described here. Moreover, it is possible to replace a part of the configuration of one example of a certain embodiment with the configuration of another example. Further, it is also possible to add a configuration of another example to the configuration of one example of a certain embodiment.
