Description

 Balanced motion device  

The present invention relates to a balanced exercise device that naturally rides in order to maintain its own posture as if the user riding on the platform is riding on the balance ball.

Currently, there is a kind of exercise device called balance ball (fitness ball) circulating in the market. The balance ball is a user who sits on the balance ball or the body is in close contact with the balance ball to train a sense of balance. The balance ball has a size of about 50 cm to 100 cm and has a spherical shape, so that it is easy to roll on the ground or the like. Further, although the balance ball is inflated by air or the like injected therein, it is flattened and deformed when subjected to the user's weight. That is, in the state where the user is loaded, the balance ball is deformed or rolled and is extremely unstable, and the user cannot be carried on the unstable balance ball without twisting or tilting the body. In other words, after the user rides on the balance ball, the exercise is performed in order to maintain the posture rather than intentionally, which is a beneficial exercise for the body.

In addition, the balance ball can not only exercise the body, but also be effective in exercising balance, correcting posture, and improving muscle strength.

However, skilled use of the balance ball requires experience, and a lot of training is required in order to skillfully use the balance ball for exercise. For example, even if a beginner wants to exercise a "sitting on a balance ball" with a high exercise effect, it is not easy for an inexperienced user to perform this exercise because of the need for a high degree of balance. .

In addition, even if there is a certain degree of balance ball use experience, there is a possibility that the balance ball rolls in an unexpected direction during use, thereby causing a dangerous situation in which the user falls to the ground or the like.

Therefore, Patent Document 1 discloses a technique relating to a "balanced ball auxiliary frame" in which the periphery of the balance ball is surrounded by the frame member in order to avoid the above-described dangerous situation, so that the balance ball can be prevented from rolling unexpectedly.

However, when exercising with the balance ball auxiliary frame as in Patent Document 1, since the scroll of the balance ball is reliably restricted by the auxiliary frame, the user does not need to balance on the balance ball. In other words, in the exercise machine of Patent Document 1, the user does not need to try to maintain the posture on the unstable balance ball, and thus the original exercise effect cannot be obtained, and it is doubtful whether or not sufficient exercise can be performed.

Therefore, in order to eliminate the danger that the balance ball rolls in an unexpected direction to cause the user to fall, and to obtain the effect of balancing the ball, an exercise machine inspired by the movement of the balance ball is developed.

For example, Patent Document 2 discloses a moving device in which a balance ball is mounted under a disc shape of a hard plastic or aluminum that a user can ride.

Hereinafter, an embodiment of the balance motion device 1 according to the present invention will be described with reference to the drawings.

Further, the directions for explanation are appropriately illustrated in the drawings. In the following description, the balance motion device 1 will be described in detail using the directions in the drawings.

 [First Embodiment]  

The balance motion device 1 includes a riding portion 2 that the user M can ride in various postures, a swing mechanism 3 that is disposed below the riding portion 2 and that swings the riding portion 2 forward and backward, and a driving mechanism 4 that drives the swing mechanism 3, And a base portion 5 in which the swing mechanism 3 and the drive mechanism 4 are incorporated and can be placed on the bottom surface F. This balance motion device 1 enables the user M to perform a motion similar to a conventional exercise device called a balance ball (fitness ball) (hereinafter, this motion is sometimes referred to as "balance motion").

That is, in the balance motion device 1 of the present embodiment, the user M can perform the posture of the user M sitting on the balance ball on the unstable balance ball, and arbitrarily (naturally) twist and stretch the body. Balance the movement of the same movement. Specifically, the balance motion device 1 of the present embodiment swings the riding section 2 on which the user M rides mechanically, and disturbs the posture of the user M in the same manner as when sitting on the balance ball, thereby causing the user M to perform the operation. A device that balances motion.

Hereinafter, first, the riding section 2, the swinging mechanism 3, the driving mechanism 4, and the base portion 5 constituting the balance motion device 1 of the present embodiment will be described.

As shown in FIG. 1 and FIG. 3, the base portion 5 is a flat plate having a substantially circular shape in plan view, and has a diameter smaller than the diameter of the riding portion 2 (described later in detail) having a circular shape in plan view. The bottom surface (lower surface) of the base portion 5 is formed into a flat surface shape, and can be stably placed on the floor surface F or the like. Further, the base portion 5 is provided with a swing mechanism 3, a drive mechanism 4, and a control unit (not shown) that controls the two mechanisms.

When the bottom surface of the base portion 5 is formed into a flat surface shape, the base portion 5 can be stably placed on the floor surface F or the like, and the balance motion device 1 does not move substantially horizontally like the balance ball rolls. Thereby, there is no possibility that the balance ball rolls in an unexpected direction and the user falls.

In addition, the structure of the base portion 5 is not particularly limited, and may be a structure that can be stably supported on the floor surface F during the operation of the apparatus. Further, a housing that is disposed to wrap the base portion 5 may be provided.

Above the swing mechanism 3 and the drive mechanism 4, the riding section 2 in which the user M can ride in various postures is disposed.

The riding section 2 has a shape in which the spherical body is divided into two in the horizontal direction at a position of about 1/5 from the distal end, and only the divided upper side portion is left to remove the lower side portion. In other words, the boarding portion 2 has a shape in which an umbrella of a dome shape or an umbrella portion of a mushroom is opened.

In detail, the riding section 2 is configured to have a circular shape having a diameter larger than the diameter of the base portion 5 in plan view, and the center position of the base portion 5 substantially coincides with the center position of the riding portion 2, so that when viewed from above, The base portion 5 is hidden and the base portion 5 is not visible.

The boarding portion 2 has a convex shape that is upwardly facing in a side view and has a dome shape of a semicircular shape. In the case of the present embodiment, the riding portion 2 is formed such that the center portion is curved by about 50 mm to 150 mm higher than the edge portion, and the user can ride on the center portion provided at the height position in a balanced manner. When the riding section 2 is formed in the above-described convex shape, it is difficult for the user M to sit on the riding section 2 stably, and the user M can perform the balancing exercise.

Further, although the riding portion 2 shown in the drawing has a circular shape, the present invention is not limited thereto, and may have an elliptical shape. In other words, the length of the riding unit 2 in the front-rear direction and the length in the left-right direction may be different. Further, the riding portion 2 may have a non-circular shape in plan view, and may have a quadrangular shape or a hexagonal shape, for example. The riding section 2 is not limited to a semicircle in side view, and may be, for example, a triangular shape (mountain shape) of rounded corners. That is, it may be a pyramid shape when it is squint.

Specifically, the inside of the riding section 2 has a dome-shaped core body 6 formed of a hard plastic or the like, and an intermediate material 7 made of urethane or the like is disposed on the entire upper surface of the core body 6, and further A cover material 8 formed of ruthenium rubber or the like is disposed outside the intermediate material 7.

That is, the above-mentioned intermediate material 7 is completely covered with the core 6 from above, and the cover material 8 covers the outer side of the intermediate material 7, in other words, the laminate of the cover material 8 (upper portion) and the intermediate material 7 (lower portion) is double-layered. structure. Further, the intermediate material 7 is formed to have a thickness of about 50 mm to 100 mm on the core body 6 in such a manner as to emulate the dome-shaped outer shape of the core body 6. When the riding section 2 is formed in a laminated structure or the thickness of the intermediate material 7 is increased as described above, the surface of the riding section 2 has a certain degree of elasticity, and the user M can be given a good feeling of comfort.

Further, a plurality of anti-slip ribs for preventing the user from slipping from the riding portion 2 are formed on the upper surface of the riding portion 2. Each of the non-slip ribs is formed in an annular shape centering on the center portion of the boarding portion 2, and a plurality of non-slip ribs having different diameters are formed at intervals from the center portion of the boarding portion 2 toward the edge portion, thereby preventing sitting on the riding portion. The user M at the center of the second portion slides toward the edge portion.

In addition, the boarding unit 2 has a width that can be safely boarded even when the user M is oscillated (in the present embodiment, a width of a circular shape having a diameter of about 500 mm to 700 mm when viewed from above), and the covering material 8 A certain degree of friction is achieved between the user M and the user M, so that the user M can ride on the riding section 2 stably.

Moreover, the riding section 2 is swung by a swinging mechanism 3 which will be described later, for example, toward the front, rear, left and right along the eight-shaped rail. Therefore, since the oscillating trajectory in the front-rear direction and the swaying trajectory in the left-right direction are different, it is preferable that the riding portion 2 is marked with a mark indicating the front-rear direction and the left-right direction (indicating which direction the body is facing when seated). As such an imprint (mark), for example, marking may be performed on the front side of the riding section 2, or a line indicating the left-right direction or a line indicating the front-rear direction may be engraved on the surface of the riding section 2.

In addition, by embedding LED illumination or the like that emits various kinds of light in the inside of the riding section 2 (below the covering material 8) or forming various patterns on the surface of the riding section 2 (the surface of the covering material 8), it is possible to form an aesthetic appearance. Exercise device 1. In addition, LED illumination, various patterns, and the like can also be used for the above marking.

Further, a flexible elastic member may be provided on the outer periphery of the riding portion 2 so as to cover the riding portion 2 from the periphery. Thereby, by covering the riding section 2 with the elastic member, it is possible to reliably avoid the problem of being caught between the riding portion 2 and the floor F, thereby improving safety. As the elastic member, it is conceivable to provide the covering material 8 constituting the riding portion 2 so as to protrude in a substantially horizontal direction (projecting portion, crotch portion).

Further, a lining material (not shown) is provided between the lower side of the riding section 2 and the base portion 5 (or the opening 4 of the casing). The lining material makes it impossible to see the swing mechanism 3 and the drive mechanism 4 from the outside.

Further, an annular sponge (not shown) that completely surrounds a gap between the lower side of the riding portion 2 and the base portion 5 (that is, a gap that is vacant in the vertical direction and opens toward the periphery) may be formed in advance and used. The sponge blocks the upper and lower gaps.

Specifically, a lining material capable of enclosing the upper and lower gaps is provided in advance, and a sponge having a thickness of several centimeters (cm) is disposed on the inner side of the lining material. It is also possible to form the lining material into a two-layer structure and to configure a sponge body inside thereof.

The upper edge of the lining material in the above state is attached to the lower end of the riding portion 2, and the lower edge of the lining material is attached to the base portion 5 (or the edge of the opening on the casing). In this case, by applying a tension in the vertical direction to the lining material in advance, the sponge body is stretched up and down, and the strength is increased. Therefore, the swing mechanism 3 that allows the fingers of the user M to protrude from the outside into the opening can be reliably prevented. In the drive mechanism 4.

Next, as shown in FIGS. 4 and 5, a swing mechanism 3 and a drive mechanism 4 for driving the swing mechanism 3 are disposed above the base portion 5 and below the boarding portion 2, wherein the swing mechanism 3 is used to make the swing mechanism 3 The riding section 2 reciprocates in the front-rear direction and the left-right direction, and the riding section 2 generates a twisting operation around the vertical direction.

The swing mechanism 3 includes a rotary shaft 10 that is rotated by the drive of the drive mechanism 4, a support member 11 that supports (supports) the riding portion 2 from below, and converts the rotational motion of the rotary shaft 10 into a reciprocating swing motion in the left-right direction (translation The movement portion is transmitted to the conversion portion 12 of the support member 11 and the restriction portion 13 that restricts the rotation of the support member 11 with the rotation shaft 10.

The rotating shaft 10 is stretched over the base portion 5 below the riding portion 2 so that the axial center thereof faces the left-right direction. The rotating shaft 10 is rotatably supported by a bearing 14 around an axis oriented in the left-right direction. Further, the right end side of the rotary shaft 10 is inserted into the speed reducer 26 of the drive mechanism 4, and the left end side of the rotary shaft 10 is rotatably supported by the rotary shaft support portion 17 via the bearing 14 (to stand up from the upper surface of the base portion 5 upward) The way to extend the components).

The support member 11 supports the riding section 2 from below. The support member 11 has a mounting portion 15 on which the riding portion 2 is attached, and a supporting portion 16 that supports the mounting portion 15 from below.

The placing portion 15 is a plate-like member that is disposed in the horizontal direction and has a thickness that can withstand the load (weight) of the user M. The support portion 16 has an expanded shape that expands from the lower end toward the upper end when viewed from the front. In other words, the support portion 16 is a member that is gradually widened from the lower end side toward the upper end side so as to be wider at the upper end side and has an inverted triangular shape (funnel shape) in a cross section having a thickness in the left-right direction. In addition, the lower end of the support portion 16 also has a certain thickness. Further, regarding the support member 11, the placing portion 15 and the support portion 16 can be integrally formed.

By designing the mounting portion 15 and the support portion 16 integrally or the like as described above, the riding portion 2 can be disposed at a lower position than the conventional moving machine using the spherical balance ball, so that the base portion 5 can be provided. In other words, the height of the ground F to the apex of the riding section 2 is much lower than that of the existing balance ball. Therefore, the user M does not feel the danger of falling to the ground F, so that the movement can be performed with peace of mind.

As shown in FIG. 5, the lower end (base end) side of the support member 11 is provided with a conversion portion 12 (conversion portion 12 provided in the swing mechanism 3) for converting the rotational driving force from the rotary shaft 10 into a reciprocating motion.

The conversion unit 12 converts the rotational driving force from the rotating shaft 10 into the above-described oscillating motion, and transmits it to the riding portion 2 that operates together with the support member 11. The conversion portion 12 has a rotation boss portion 20 that is fixed to the rotation shaft 10 so as to rotate integrally with the rotation shaft 10, and a ring that is provided at the base end of the support member 11 and that is fitted to the outer circumference of the rotation boss portion 20. The fitting portion 21 and the restricting portion 13 that restricts the support member 11 to rotate together with the rotating shaft 10.

The rotary boss portion 20 is externally fitted to the rotary shaft 10, and an outer peripheral surface thereof is provided with a cam surface that is inclined with respect to the rotary shaft 10. Further, the hole portion through which the rotary shaft 10 is inserted in the rotation boss portion 20 is formed to be eccentric with respect to the center of the outer circumference of the rotation boss portion 20. That is, the rotation boss portion 20 rotates in the same manner as the axis of the rotation shaft 10 is inclined. Further, the inclination of the rotary boss portion 20 (cam surface) is an inclination at which the support member 11 can realize the oscillating motion.

The annular fitting portion 21 is formed on the base end of the support member 11, and is externally fitted to the rotary boss portion 20 via the bearing 22 in a state of being relatively rotatable. The support member 11 performs a reciprocating swing motion by the tilt rotation and the eccentric rotation of the rotary boss portion 20.

The restricting portion 13 is for restricting the annular fitting portion 21 from rotating together with the rotating boss portion 20. The restricting portion 13 is disposed below the rotating shaft 10 .

The restricting portion 13 has a restricting pin 23 provided on the proximal end side of the support member 11, and a restricting groove 24 provided at a position opposed to the restricting pin 23, and the restricting pin 23 is slidably fitted into the restricting groove 24.

In the present embodiment, the regulating pin 23 is a columnar projection and is provided to protrude downward from the base end of the support member 11 (below the annular fitting portion 21). Further, the restricting groove 24 is provided below the restricting pin 23 and on the base portion 5. The restriction groove 24 is formed as a long groove in the left-right direction, and the restriction pin 23 is slidably inserted into the restriction groove 24 in the left-right direction.

A drive mechanism 4 that rotates the rotary shaft 10 is disposed on the right end side of the rotary shaft 10 and on the base portion 5.

The drive mechanism 4 has a drive motor 25 that outputs a rotational driving force, and a reduction gear 26 that decelerates the rotational driving force output from the drive motor 25 to a predetermined speed. The speed reducer 26 has a gear mechanism 28 that is decelerated to a predetermined speed and a gear box 29 that houses the gear mechanism 28. The drive motor 25 is configured such that the output shaft is located on the lower side of the rotary shaft 10 and faces forward. Further, an output shaft of the drive motor 25 is inserted into the speed reducer 26, and is coupled to the rotary shaft 10 via a gear mechanism 28.

A power transmission mechanism 27 that reliably rotates the rotary shaft 10 together with the conversion unit 12 is provided between the conversion unit 12 and the rotating shaft 10 . That is, the power transmission mechanism 27 prevents the rotation boss portion 20 from slipping on the rotating rotating shaft 10 when the swinging motion is performed to prevent the large load applied by the user M.

In the present embodiment, the power transmission mechanism 27 is a spline formed on the outer circumferential surface of the rotating shaft 10. By the action of the spline, the rotary boss portion 20 does not slip on the rotary shaft 10. In the present embodiment, the spline is formed on the right side of the rotary boss portion 20.

 [actuation form]  

The operation mode of the balance motion device 1 having the above configuration will be described.

The user M rides on the riding section 2 in various postures with the power off (OFF) (described after the posture). Then, the start switch 30 provided in front of the riding section 2 is turned on.

Then, the drive motor 25 of the drive mechanism 4 outputs the rotational driving force from the output shaft. The rotational driving force is decelerated by the speed reducer 26 to a predetermined speed, and transmitted to the rotating shaft 10 via the gear mechanism 28. At the same time, the rotary boss portion 20 mounted on the rotary shaft 10 rotates together with the rotary shaft 10. Further, since the rotary shaft 10 and the rotary boss portion 20 are meshed by the power transmission mechanism 27, they can be reliably rotated together.

The support member 11 that is externally fitted to the rotary boss portion 20 via the annular fitting portion 21 is intended to rotate in the same direction as the rotation direction of the rotary shaft 10. At this time, since the regulating pin 23 provided under the annular fitting portion 21 slides in the restricting groove 24, the co-rotation of the rotating boss portion 20 and the supporting member 11 is restricted.

The cam surface formed on the outer peripheral surface of the rotary boss portion 20 is inclined with respect to the rotating shaft 10. Further, the restriction pin 23 slides along the restriction groove 24 that is long in the left-right direction. Therefore, the support member 11 performs a reciprocating swing operation toward the right and left and the front and rear as the rotation shaft 10 rotates.

That is, when the front end portion of the riding portion 2 is swung toward the right side and the upper surface thereof is inclined downward to the left, the rear end portion is swung toward the left side and the upper surface thereof is inclined upward to the upper right. On the other hand, when the front end portion of the riding portion 2 is swung toward the left side and the upper surface thereof is inclined downward to the right, the rear end portion is swung toward the right side and the upper surface thereof is inclined upward to the left. The swing mechanism 3 is configured to generate a swinging motion in which the front end portion and the rear end portion of the riding portion 2 connected to the supporting member 11 are opposite to each other with the center of the riding portion 2 as viewed in the plan view, in other words, the compound rotation Exercise (complex 8 word movement).

Regarding the boarding method on the riding section 2 that performs the above operation, various methods can be considered.

For example, as shown in FIG. 6, it is possible to ride in a posture of sitting cross-legged, that is, a meditation posture. As shown in Fig. 7, the hips may be seated on the riding section 2 and the legs may be suspended. By performing the swinging motion while maintaining the body state, it is possible to significantly improve the sense of balance and exercise the muscles of the whole body. As shown in Fig. 8, it is also possible to ride in a standing position.

In any posture, since the riding portion 2 has a dome shape and is easily lost in balance, and the riding portion 2 performs the swinging motion, the user M can exercise the muscles of various parts of the body and can significantly improve the sense of balance.

Further, the ride portion 2 may be placed on the riding portion 2 as shown in FIG. 9 or the back portion may be mounted on the riding portion 2. In this state, by swinging the riding section 2, muscle movement centered on the back of the user M can be realized.

Further, as described above, since the height from the base portion 5 (in other words, the ground F) to the apex of the riding portion 2 is extremely lower than that of the conventional balance ball, the user M can ride on the riding portion 2 in various postures with peace of mind. .

As described above, by using the balance motion device 1 of the present invention, the user M can safely use it without feeling dangerous, and can reliably overcome the existence of the original balance ball of the user M's body. The effect of "improving the balance of the user M and improving the muscle strength" achieved by the "unstable feeling".

 [Second Embodiment]  

Hereinafter, a second embodiment of the balance motion device according to the present invention will be described.

The balance motion device 1 of the second embodiment includes a riding portion 2 having an upward convex shape, a swinging mechanism 3 disposed below the riding portion 2, and swinging the riding portion 2 back and forth or left and right, and a driving mechanism for driving the swinging mechanism 3. 4. The base portion 5 for arranging the swing mechanism 3 and the drive mechanism 4 and capable of being placed on the floor F, the maximum difference between the balance motion device 1 of the second embodiment and the balance motion device 1 of the first embodiment The base portion 5 has a downward convex shape.

The base portion 5 is configured such that the front portion of the riding portion 2 protrudes downward from the edge portion in a side view, and it is preferable to change the base portion 5 downward by injecting air into the base portion 5 The degree of bulging.

Specifically, as shown in FIGS. 10 and 11, the base portion 5 divides the sphere into two parts in the horizontal direction from a position about 1/5 of the lower end, and leaves only the divided lower portion. The upper portion is removed from such a shape. In other words, the base portion 5 has a shape in which the umbrella opened in a dome shape is inverted or a shape in which the mushroom portion of the mushroom is inverted.

The base portion 5 has a circular shape having a diameter smaller than the diameter of the riding portion 2 in plan view, and the center position of the base portion 5 substantially coincides with the center position of the riding portion 2.

The base portion 5 has a dome shape of a semicircular shape that is convex downward in a side view. The swing mechanism 3 and the drive mechanism 4 are disposed substantially at the center portion of the base portion 5 in the horizontal direction, and the ride portion 2 is attached to the upper side of the swing mechanism 3. Further, the swing mechanism 3 and the drive mechanism 4 are disposed on the upper surface or the inside of the base portion 5, and the base portion 5 itself is disposed such that the tip end of the convex portion comes into contact with the floor surface F.

In this way, when the base portion 5 has a downward convex shape and is placed on the floor surface F in this shape, when the user M rides on the upper surface of the boarding portion 2, the base portion 5 is unstable on the ground. The state (the tumbler state) allows the user M to ride while maintaining balance. In other words, when the base portion 5 is formed into such a downward convex shape, the instability of the riding portion 2 is increased, and it is more difficult for the user M to perform the riding stably, so that the user M can be more effectively performed. Balanced movement.

Balance the exercise device 1.

Further, in the riding portion 2, the gap portion 30 (the gap portion 30 formed between the core body 6 and the covering material 8) may be formed in advance instead of the intermediate material 7, and air may be injected into the gap portion 30 from the outside. The same action as the intermediate material 7 is produced. By injecting a large amount of air into the cavity portion 30, the curvature (protrusion degree) of the convex shape of the riding portion 2 can be increased, and a strong balancing motion can be applied to the user M. On the other hand, by injecting a small amount of air into the gap portion 30, the curvature (protrusion degree) of the convex shape of the riding portion 2 can be reduced, and the balance motion with respect to the user M can be weakened.
