Description

  The present invention relates to an automatic twister.

2. Description of the Related Art An exercise assist device (so-called twister) that makes it easy for a person (user) to ride in a standing posture on a disk that can be rotated forward and backward and to twist the waist alternately left and right is known. (See, for example, Patent Document 1). This type of twister includes a type in which a handle is provided so that the operation of twisting the waist can be performed stably and a type in which a handle is not provided in consideration of convenience such as carrying and storage.
Recently, exercise aids have also been proposed in which the upper surface of a disk on which a person rides is tilted so that this type of exercise further enhances the effect of twisting the waist and stretching (stretching) each part (Patent Document) 2).
JP 55-26946 A JP 2004-136060 A

In a conventionally known exercise assist device, a user who rides on a disk twists his / her waist alternately by his / her own intention and by his / her own movement. For this reason, there is no fixed movement, and the twist angle of the hips, the twist speed, and the continuous exercise time are different each time.
For this reason, this is the cause of the complaints that muscles have been attached to the body, despite the purpose of trying to diet and shape up, etc. It has been reported that there have been cases of mishaps.

By the way, in the exercise assistance device (Patent Document 2) in which the upper surface of the disk is inclined, only the upper surface is inclined, and the rotation axis of the disk is perpendicular to the installation surface on which the exercise assistance device is installed. Was provided. For this reason, it is clear that this exercise assisting device cannot obtain a noticeable twist or stretch effect as described in Noh.
That is, as shown in FIG. 8 and FIG. 9, it is assumed that the disc 100 with the inclined upper surface is ridden with the left and right heels on the lower side and the left and right toes on the higher side. In this case, even if the disk 100 is rotated to the left and right, the left and right eyelids only rotate horizontally (turn). Accordingly, at this time, there is no difference in height between the left and right eyelids, and the height H from the installation surface G does not change between the neutral position and after the right turn or after the left turn.

Of course, the situation of horizontal rotation (turning) is the same with respect to the toes. Therefore, when the disc 100 is rotated left and right, there is no difference in height between the left and right toes, and the height from the installation surface G is also the same. There is no change between the neutral position and the right rotation or the left rotation. As a result, no weight shift occurs in the vertical direction for the user who rides on the disk.
Therefore, except for the point where the ankle bends upward from the heel to the toes, there is almost no difference from the case where the left and right alternate twist exercises are performed on a disk with the upper surface horizontal, It is difficult to obtain a remarkable twist effect or stretch effect. Needless to say, these are the same when riding in the opposite direction with respect to the disk.

  The present invention has been made in view of the above circumstances, and when performing a twisting exercise on the waist, the twisting angle, the twisting speed, the exercise time, and the like can be stably and consistently performed. An object is to provide an automatic twister that can achieve the effects (diet, shape-up, exercise deficiency, etc.) without excess or deficiency.

In order to achieve the above object, the present invention has taken the following measures.
That is, the automatic twister according to the present invention has a base portion placed on the installation surface, and is held on the upper portion of the base portion so as to be able to rotate forward and backward around the vertical axis, and the user can stand up on the upper surface. A rotating plate in which a space is provided and the upper surface is inclined with respect to the installation surface; and a repetitive driving unit that automatically rotates the rotating plate forward and backward repeatedly within a predetermined angle range. Features.
In such a configuration, the user who rides on the rotating plate does not twist his / her waist alternately by his / her intention and his / her movement, but in accordance with the forward / reverse rotation of the rotating plate by the repetitive drive unit, It is just to keep the upright posture stopped in front.

That is, when performing the twisting exercise of the waist, the twisting angle, the twisting speed, the exercise time, etc. can be performed stably and constantly. Therefore, the effects intended by the user (diet, shape up, lack of exercise, etc.) can be obtained without excess or deficiency.
Preferably, the repetitive drive unit includes an electric motor and a power conversion unit that extracts the forward / reverse repetitive rotation from the rotational drive of the electric motor, and the rotary plate is between the upper and lower sides of the base unit and the rotary plate. It is good to provide it within the plane projection range.
By doing so, the apparatus can be made compact, easy to carry and store, and can be manufactured at low cost.

The rotating plate has a disc shape, and the rotating shaft of the rotating plate is provided at the center of the rotating plate and perpendicular to the upper surface of the rotating plate, and the rotating shaft is inclined with respect to the installation surface. It is very preferable to adopt a configuration.
In this way, if it is assumed that the left and right heels are placed on the lower plate and the left and right toes are directed to the higher plate, the rotating plate is rotated in one direction. (For example, turning to the right) The height of the heel from the installation surface is low on the right foot and the left foot is high. On the left, the height of the heel from the installation surface is high on the right foot and the left foot is low. In other words, the height of the left and right eyelids will change alternately.

Moreover, when attention is paid to the heel of the right foot, the height of the heel after the right rotation is lower than that in the neutral position. Similarly, when attention is paid to the heel of the left foot, the height of the heel after the left rotation is lower than that in the neutral position. Since the rotating plate always passes through the neutral position between the rightward rotation and the leftward rotation, the weight movement in the vertical direction is inevitably applied to the user who rides on the rotating plate. Become.
From these facts, while the rotating plate alternately repeats forward and reverse rotation, the position of the center of gravity of the user fluctuates periodically. The potential reaction to try to rectify it works. As a result, the user can efficiently perform a twisting action on the waist and a stretching action on each part of the body.

Needless to say, these are the same when the user rides in the reverse direction with respect to the rotating plate.
When the rotation axis of the rotating plate is tilted in this way, it is preferable that the base portion has a device mounting surface that is parallel to the upper surface of the rotating plate.
By doing so, the repetitive drive unit can be provided in a plane parallel state with respect to the device mounting surface of the base portion, and at this time, the space between the repetitive drive unit and the rotating plate can also be in a plane parallel state. Can be simplified.

  With the automatic twister according to the present invention, the twist angle, the twist speed, and the exercise time can be stably and constantly performed during the twisting exercise of the waist, and thus the effects intended by the user (diet, shape up) , Exercise deficits, etc.) can be obtained without excess or deficiency.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
1 to 5 show an embodiment of an automatic twister 1 according to the present invention. As apparent from FIG. 3, the automatic twister 1 includes a base portion 2, a rotating plate 3 that is rotatably supported on the upper portion of the base portion 2, and a rotating plate 3 that rotates forward and backward repeatedly. And a repetitive driving unit 4 to be operated.
Here, the forward rotation direction and the reverse rotation direction only indicate that the circumferential rotation of the rotating plate 3 is changed in the opposite direction. The right side is not limited. For example, if the forward rotation direction is the clockwise direction (right direction), the reverse rotation direction is naturally the counterclockwise direction (left direction).

In the present embodiment, the overall shape of the automatic twister 1 is a disk shape having a predetermined thickness (height), and the upper surface thereof is inclined. The inclined upper surface is formed by the rotating plate 3 described above.
The base portion 2 includes a bottom plate 10, an inclined leg portion 11 provided on the bottom plate 10, and an intermediate partition plate 12 provided in an inclined state by the inclined leg portion 11. The upper surface of the partition plate 12 is provided so as to be parallel to the tilt direction of the upper surface of the rotating plate 3.
The upper surface of the partition plate 12 serves as a device attachment surface 13 for the base portion 2 and is used to attach the repetitive drive portion 4.

As is clear from FIG. 4, the partition plate 12 (device mounting surface 13) is formed in a disc shape. A pad 16 is provided on the bottom surface of the bottom plate 10 to provide a non-slip effect on the installation surface G. The pad 16 preferably has a vibration absorbing property so that a soundproofing effect or the like can be expected.
The base portion 2 is surrounded by an arcuate wall-shaped casing 17 having a height that rises at the outer peripheral portion of the bottom plate 10 and reaches the rotating plate 3.
The upper surface of the rotating plate 3 is formed with a space for the user to ride. In the present embodiment, it is formed by a circular plate having a diameter slightly exceeding 400 mm. A surface material 20 is preferably affixed to the upper surface of the rotating plate 3 to provide a non-slip effect for a user who rides in a standing position on the rotating plate 3. The surface material 20 can be formed of, for example, rubber, soft resin, sponge sheet, carpet fabric, artificial turf, or the like.

In addition, protrusions that stimulate the pressure points on the soles can be provided on the upper surface or the surface material 20 of the rotating plate 3.
A rotating shaft 23 is provided on the lower surface of the rotating plate 3 so as to protrude downward via a shaft holder 22. The rotating plate 3 and the rotating shaft 23 are integrally rotatable. The rotary shaft 23 is held so as to be rotatable forward and backward with respect to a bearing portion 24 provided on the intermediate partition plate 12 of the base portion 2. Further, the rotary shaft 23 is positioned at a substantially central position of a space where a user gets on the rotary plate 3 so that the forward and reverse rotation of the rotary plate 3 can be obtained smoothly and stably. .

The rotating shaft 23 is provided orthogonal to the direction of inclination of the upper surface of the rotating plate 3, and is therefore inclined with respect to the installation surface G on which the base portion 2 is installed. This inclined state (angle α) is provided in order to obtain a predetermined angle within a range where the inclination θ (see FIG. 2) of the upper surface of the rotating plate 3 with respect to the installation surface G is greater than 0 ° and equal to or less than 30 °. In the present embodiment, the inclination θ is 7 °.
If a local uneven load is applied to the outer peripheral portion of the rotating plate 3 when a user gets on or off the rotating plate 3, the rotating shaft 23 receives a cantilever concentrated load. However, in order to prevent the occurrence of rotation obstruction, deformation or breakage of each member due to this, a plurality of peripheral stable support portions 25 are provided along the outer peripheral portion of the lower portion of the rotary plate 3. It has been.

This peripheral portion stable support portion 25 has a support column 26 erected on the outer peripheral portion of the middle partition plate 12, so that a free rotating tool 27 such as a bearing or a rolling ball is placed along the rotation direction of the rotary plate 3 at its upper end portion. By holding the rotatable tool 27 in contact with the lower surface of the rotating plate 3, the rotating plate 3 can rotate stably around the rotating shaft 23 while always maintaining a constant height. To.
As described above, since the rotary plate 3 and the partition plate 12 are in a plane parallel state to each other, the peripheral portion stable support portion 25 has the same height of the support pillars 26, and the production and assembly are related. Unnecessary work and costs are prevented from occurring.

A driven gear 28 is provided on the rotary shaft 23 so as to be integrally rotatable (see FIG. 5). The driven gear 28 serves as a transmission end (output end) when the repetitive driving unit 4 rotates the rotating plate 3.
The repetitive driving unit 4 is provided in a plane parallel state with respect to the upper surface (device mounting surface 13) of the intermediate partition plate 12, and is within the plane projection range of the rotating plate 3 between the base unit 2 and the rotating plate 3. It is provided to fit in. The repetitive drive unit 4 includes an electric motor 30 and a power conversion unit 31.
The power conversion unit 31 is a place to extract power for rotating the rotating plate 3 forward and backward repeatedly from the rotational drive of the electric motor 30.

In this embodiment, the power conversion unit 31 employs a crank mechanism. That is, a crank wheel 36 continuously rotated in one direction through a meshing portion of a worm gear 34 and a worm wheel 35 with respect to a drive shaft 33 extended from the electric motor 30 via a speed reducer 32, and the crank wheel 36 And a slider 40 that linearly reciprocates along the guide bar 39 by receiving a one-way circumferential movement of the cam follower 37 provided at an eccentric position (near the outer peripheral portion) by the cam groove 38. Yes.
The cam groove 38 provided in the slider 40 is formed to have a groove length equal to or greater than the diameter of the circumferential track drawn by the cam follower 37 when the crank wheel 36 rotates. The groove direction and the sliding direction of the slider 40 are orthogonal to each other on the plane of the circumferential orbit drawn by the cam follower 37.

A rack rail 41 is provided on the side surface of the slider 40, and the rack rail 41 is meshed with the driven gear 28 provided so as to be integrally rotatable with the rotary shaft 23 as described above.
With such a configuration, in the repetitive driving unit 4, when the crank wheel 36 is continuously rotated in one direction, the cam follower 37 moves circumferentially in one direction, and the cam follower 37 presses the groove inner surface of the cam groove 38. Due to the force, the slider 40 moves back and forth along the guide bar 39 within a predetermined range, and the reciprocating sliding of the slider 39 is transmitted from the rack rail 41 to the driven gear 28 and the rotating shaft 23, resulting in this rotation. The rotating plate 3 supported by the shaft 23 repeats forward and reverse rotation within a predetermined angle.

The angle range for rotating the rotating plate 3 forward and backward is preferably within 180 °. In this embodiment, the angle is 120 °.
Now, when the rotating plate 3 rotates forward and backward, an intermediate position of the angular range (for example, a position of 60 ° if the entire range is 120 °) is assumed to be a neutral position of the rotating plate 3 now. far. Moreover, in the inclination which the base part 2 provides to the rotating plate 3, if the virtual line which connected the uppermost position and the lowest position is made into inclination center position, the repetition drive part 4 of this embodiment will be the neutral position of the rotating plate 3. And the base portion 2 are provided so that the inclination center position of the base portion 2 matches.

That is, the rotating plate 3 is rotated by the same angle to the left and right with reference to the case where both ends of the neutral position are directed to the inclination center position (the highest position and the lowest position of the inclination). (Symmetrical rotation).
As shown in FIG. 1, the surface material 20 to be attached to the upper surface of the rotary plate 3 is provided with a display unit 43 for instructing the user's standing position (direction in which the toes and the heel are directed). It is preferable that the neutral position is determined by the display unit 43.
Such a repetitive drive unit 4 is appropriately provided with an electric circuit (not shown), and an operation switch (including a case where it is a remote control operation unit) electrically connected to the electric circuit is turned on / off. , Can be started and stopped.

Note that this electric circuit is configured so that the neutral position of the rotating plate 3 and the inclined center position of the base portion 2 always coincide with each other when the operation switch is turned off. Is preferred. By doing in this way, the boarding / alighting with respect to the rotating plate 3 becomes easy.
In addition, this electric circuit is provided with a human body detection circuit that can determine whether or not a user is on the rotating plate 3, and the repetitive driving unit 4 is provided only when the human body detection circuit is in a state of detecting a human body. It is preferable to be able to turn it on.
This electric circuit may be provided with a speed control circuit for adjusting the rotation speed of the rotating plate 3, a timer circuit for setting an off time after the on operation, and the like.

In the automatic twister 1 of the present invention having such a configuration, the user only has to ride in accordance with a predetermined standing position on the rotating plate 3 and turn on the operation switch. As a result, the rotating plate 3 starts to rotate forward and backward at a predetermined angle range and at a predetermined speed by the repetitive driving unit 4, so that the user does not twist his / her waist alternately by his / her own intention and his / her own operation. You just need to stay still so that the upper body stops in front of you and keeps you upright.
That is, when performing the twisting exercise of the waist, the twisting angle, the twisting speed, the exercise time, etc. are controlled by the repetitive driving unit 4 and can be performed stably and constantly, and the effects intended by the user (diet, shape) Can be obtained without excess or deficiency.

Here, as shown in FIG. 6 and FIG. 7, the utility will be described on the assumption that the left and right heels are put on the rotating plate 3 with the left and right toes facing the high platen side.
6, when is rightward rotate the rotating plate 3 from the neutral position, the height H _R of the heel of the right foot from the installation surface G is a lower than the height H _L heel left from the installation surface G Become. Moreover, putting a reference height H the height of the heel of the left and right feet from the installation surface G at the time of the neutral position before rotating, the height H _R of the heel of the right foot after the right turning, the reference high The height H _L of the heel of the left foot is further higher than the reference height H.

That is, the relationship is H _R <H <H _L.
On the other hand, in FIG. 7, when is leftward rotate the rotating plate 3 from the neutral position, the height H _L heel left from the installation surface G, as compared to the height H _R of the heel of the right foot from the installation surface G Become low. In addition, when the height of the heels of the left and right feet from the installation surface G is set to the reference height H at the neutral position before the rotation, the height _HL of the heel of the left foot after the left rotation is the reference height. The height H _R of the right foot heel is further higher than the reference height H.
That is, the relationship H _L <H <H _R is satisfied.

Thus, it can be seen that when the rotating plate 3 is repeatedly forward and reverse rotated toward the left and right sides of the neutral position, the heights H _L and H _R of the left and right ridges alternately change. Of course, when moving from a right-handed turn to a left-handed turn and from a left-handed turn to a right-handed turn, the rotating plate 3 always passes through the neutral position. Inevitably, the weight shift in the vertical direction will act.
From these facts, when the rotating plate 3 alternately repeats forward and reverse rotation, when the heel of the right foot is low, the weight of the user is heavily loaded on the right foot, and the user is There is a potential reaction to move weight to the left to correct the frontal upright posture against both left and right weight shifts that would occur.

Here, even if the difference in height between the left and right heels is only 1 cm, the sense of balance exerted by humans as an instinct acts sensitively. Substantial and ambitious weight shifts) occur.
Similarly, when the heel of the left foot is low, the weight of the user is heavily loaded on the left foot, and the user is resisted from both lateral movement and vertical weight movement that is about to occur at this time, There is a potential reaction to move weight to the right to correct the upright posture. This causes the user to have an effective twist action (substantial and ambitious weight shift) on his left half.

As a result, such an effective twisting action is repeated alternately on the left and right, and a highly efficient stretching action is obtained at each part of the user's body.
Needless to say, these are the same when the user rides in the reverse direction with respect to the rotating plate 3.
By the way, this invention is not limited to the said embodiment, It can change suitably according to embodiment.
For example, the base portion 2 can be provided with a handle for allowing a user who is on the rotating plate 3 to catch and stand.

  The structure of the base part 2, the structure of the casing 17, the adoption mechanism of the repetitive driving part 4 and the like can be changed as appropriate.
