Description

  The present invention relates to a swivel base device and an exercise apparatus using the same. More specifically, a first base and a second base arranged facing the first base are provided, and the other is rotated with respect to either the first base or the second base. The present invention relates to a swivel base device and an exercise apparatus configured to perform a swivel motion that does not.

Conventionally, as a swivel base device 91 that swivels a swivel base 92 without changing its direction (not rotating), the principle shown in FIG. 31 is known. This includes a plurality (four) of crank members 93 as constituent elements.
Each crank member 93 includes an upper shaft 93a that is rotatably attached to the swivel base 92, a lower shaft 93b that is rotatably attached to the fixed base 91, and an axis line between the upper shaft 93a and the lower shaft 93b at a predetermined interval. And a crank arm portion 93c provided between the two so as to be in parallel with each other. Each crank member 93 has a sprocket 94 fixed to each upper shaft 93a.

A drive motor 96 is installed on the swivel base 92. A sprocket 94 is also fixed to the output shaft of the drive motor 96. A chain 95 is wound around the above five sprockets 94.
Thus, when the drive motor 96 is driven, the upper shafts 93 a are rotated in synchronization with each other, and the swivel base 92 performs a swivel motion relative to the fixed base 91. That is, the swivel base 92 performs a circular motion while keeping its direction in a certain direction (without rotating). That is, an arbitrary point on the swivel base 92 performs a swivel circular motion with a radius that is a deviation distance (separation distance) between the upper shaft 93a and the lower shaft 93b with respect to the fixed base 91 at any point.

Such a swivel base device 90 is used for various purposes.
For example, there is a mushroom medium scraping device provided with a plurality of scraping members that rotate on the swivel base 92 (see Patent Document 1). According to this, the scraping member is inserted into each of the plurality of mushroom cultivation bottles held in an inverted state so that the bottle mouth faces downward. The scraping member rotates to scrape the mushroom medium. Then, the swivel base 92 is swung by the crank member 93, so that the scraping member can move a certain distance in the horizontal direction. As a result, the mushroom culture medium can be scraped out as a whole.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the best mode relating to a swivel base device, exercise equipment and the like of the present invention will be described in detail with reference to the accompanying drawings.
FIG. 1 is a cross-sectional view showing a swivel base device 10 of the present invention. 2 is a plan view for explaining the swivel base device 10, and FIG. 3 is a plan view for schematically explaining the principle of the swivel motion of the swivel base device 10. As shown in FIG.
Reference numeral 20 denotes a fixed base, which corresponds to the first base or the second base. Reference numeral 30 denotes a swivel base which is arranged facing the fixed base 20 and corresponds to a second base or a first base. If the swivel base 30 is provided with a part on which a person rides, it can be used as an exercise device. Reference numeral 40 denotes cooperation means, and a plurality are provided so that the fixed base 20 and the swivel base 30 cooperate with each other so that the swivel base 30 rotates with respect to the fixed base 20 so as not to rotate. Reference numeral 50 denotes a separation preventing means, which is provided so as to prevent the fixed base 20 and the swivel base 30 from being separated and maintain the above-described cooperative state.

Reference numeral 41 denotes a first loop groove, which is provided in a closed loop shape in a groove shape on the surface of the fixed base 20 facing the swivel base 30. Reference numeral 42 denotes a second loop groove, which is provided in a closed loop shape on the surface of the swivel base 30 facing the fixed base 20 so as to correspond to the first loop groove 41. Reference numeral 45 denotes a sphere, which can roll on the first loop groove 41 and the second loop groove 42 so that the first loop groove 41 and the second loop groove 42 overlap at the contact point of the movement locus. It is fitted in.
That is, when viewed from a direction orthogonal to the plane on which the swivel base 30 rotates, the positional relationship between the fixed base 20 and the swivel base 30 is such that the first loop groove 41 and the second loop groove 42 are the same. The center is shifted by the moving diameter of the sphere 45 and overlapped via the sphere 45.
The cooperation means 40 is configured with the first loop groove 41, the second loop groove 42, and the sphere 45 described above as constituent elements.
In the present embodiment, the first loop groove 41 and the second loop groove 42 are formed of a metal material in order to obtain strength, and are press-fitted and fixed to a main body portion formed of a resin material.

Thus, since the cooperation means 40 is comprised, the spherical body 45 carries out a turning circular motion, rolling along the both grooves 41 and 42 within the 1st loop groove 41 and the 2nd loop groove 42. FIG. The state will be described with reference to FIG. In the present embodiment, the first loop groove 41 and the second loop groove 42 are formed in the same shape.
Reference numeral 21 denotes the center of the first loop groove, which is indicated by a dot. Reference numeral 22 denotes a locus of the center of the sphere on the fixed base, which is indicated by a one-dot chain line. Reference numeral 31 denotes the center of the second loop groove, which is indicated by a dot. Reference numeral 32 denotes a locus of the center of the sphere on the swivel, which is indicated by a two-dot chain line. Reference numeral 43 denotes a contact, which is a point where the trajectory 22 of the sphere center on the fixed base and the trajectory 32 of the sphere center on the swivel come into contact. And the arrow has shown the movement locus | trajectory of the turntable (center 31 of the 2nd loop groove). R is the turning radius of the turntable 30. In addition, the state when the sphere 45 is turned by 180 ° is indicated by a dotted line.

As is clear from this figure, the swivel base 30 turns at a turning radius R with respect to the stationary base 20 that is stationary. At this time, the sphere 45 moves in a circular motion with a radius that is half the turning radius R. In addition, the swivel diameter of the swivel base 30 is doubled compared to the diameter of the trajectory of the center of the sphere moving along the first loop groove 41 or the second loop groove 42. Therefore, according to the cooperation means 40 by this structure, there exists an effect which can expand a turning motion suitably.
Further, in the present embodiment, since the diameter of the first loop groove 41 and the diameter of the second loop groove 42 are the same, the sphere 45 rolls suitably. The frictional resistance becomes very small, and the swivel base 30 can perform a very smooth turning motion.

The cooperation means 40 should just be plural, and can obtain the stable turning motion as it is three or more. In this embodiment, five are provided, including those incorporated in the separation preventing means described later. In addition, the larger the number of linkage means 40, the better the load can be supported in a balanced manner.
Furthermore, in the present embodiment, the first loop groove 41 and the second loop groove 42 are formed in the same shape and a circular ring shape, but the present invention is not limited to this. The same effect can be obtained even if the first loop groove 41 and the second loop groove 42 are formed in an elliptical closed loop shape. Even in this case, the shocking direction change that occurs in the case of a linear rocking motion (reciprocating motion) is not performed. That is, in the case of a closed loop shape, a smooth kind of rocking motion can be obtained.

Next, the separation preventing means 50 will be described with reference to FIGS.
The separation prevention means 50 includes a separation prevention unit that is provided on at least one of the fixed table 20 and the swivel table 30 and that faces a surface opposite to the surface of the other table opposite to the other table. It has become.

As shown in FIG. Reference numeral 35 denotes a second recess, which is an example of a second opening or recess provided in the swivel base 30. Reference numeral 52 denotes a second bridging portion, which is provided in a state of being bridged in the second recess 35 in a direction intersecting with the first bridging portion 51. In addition, the second bridging portion 52 includes a separation preventing portion 54 facing the surface opposite to the surface of the first bridging portion 51 facing the swivel base 30. On the contrary, a similar part (separation preventing part 53) is present in the first bridging part 51.
Reference numeral 55 denotes a screw that fixes the first bridging portion 51 to the fixing base 20 and the second bridging portion 52 to the swivel base 30. Reference numeral 77 denotes a through hole, which is used when the screw 55 is screwed.

In the present embodiment, the separation preventing means 50 (separation preventing units 53 and 54) is provided at a substantially central portion of the swivel base device 10. For this reason, the balance is good and the swivel base 30 can move smoothly. This is because the separation preventing means 50 is in the center, so that various forces can be easily dispersed in all directions. Further, by being in the central portion, the separation preventing means 50 can be suitably incorporated to reduce the thickness.
In the present embodiment, the above-described cooperation unit 40 is also incorporated in the separation preventing unit 50. About the cooperation means 40, the code | symbol same as the code | symbol mentioned above is attached | subjected, and description is abbreviate | omitted. This also allows the swivel base 30 to move smoothly. In the present embodiment, all the cooperation means 40 including the cooperation means 40 provided in the separation preventing means 50 are arranged in the same plane. For this reason, while being able to receive a load suitably, the swivel base apparatus 10 can be reduced in thickness suitably. Moreover, it is highly stable because of its thinness, and is suitable for applications such as a stirrer.

Of course, the separation preventing means 50 is not limited to one, and a plurality of separation preventing means 50 may be disposed as appropriate.
Further, the first bridging portion 51 and the second bridging portion 52 may be formed in a rod shape to prevent separation by point contact between the rod and the rod. The shape of both bridge | crosslinking parts 51 and 52 can be suitably selected, such as plate shape and plate shape, rod shape and plate shape, and is not specifically limited.
In addition, as shown in FIG. 4, only one of the fixed base 20 and the swivel base 30 is provided with an opening or a concave portion, and two bridging portions are formed so as to intersect within the opening or the concave portion to prevent separation. May be. FIG. 4 is a cross-sectional view showing an embodiment of the separation preventing means. The same reference numerals are given to the same components as those of the above embodiment, and the description thereof is omitted. An opening 25 a is provided on the fixed base 20. The first bridging portion 51 is fixed to the fixing base 20 at both ends in a state of being spanned over the opening 25a. The first bridging portion 51 may be formed integrally with the fixing base 20 as a part of the material constituting the fixing base 20. Moreover, the 2nd bridge | crosslinking part 52 is being fixed to the flat part of the lower surface of the turntable 30 at the both ends.

Next, another embodiment of the separation preventing means will be described with reference to FIG.
FIG. 5 is a cross-sectional view showing the swivel base device 110 in which the separation preventing means 150 is disposed at the center of the device. The same reference numerals are given to the same components as those in the embodiment described above, and detailed description thereof will be omitted.
Reference numeral 151 denotes a rotating shaft. Reference numeral 152 denotes a disk portion, which is provided at the lower end of the rotating shaft 151 in a disk shape having a large diameter. The rotating shaft 151 and the disc portion 152 are components provided on the swivel base 30. Among these, the disc part 152 is a separation preventing part facing the surface 20 a opposite to the surface of the fixed base 20 facing the swivel base 30.
The rotating shaft 151 is mounted on the swivel base 30 via a bearing 154 so as to be rotatable (spinning). Reference numeral 155 denotes a stopper portion, which is formed in a flange shape having a large diameter at the upper end portion of the rotating shaft 151. Thereby, it can prevent that the rotating shaft 151 and the disc part 152 fall off.

Reference numeral 160 denotes an opening through which the rotation shaft 151 is inserted. The opening 160 is formed in such a size that the turning motion of the rotating shaft 151 accompanying the motion of the turntable 30 is not hindered. By this opening 160, the disc part 152 can be positioned as a separation preventing part.
Reference numeral 161 denotes a recess, which is provided on a surface of the fixed base 20 opposite to the surface facing the swivel base 30. The concave portion 161 can accommodate the disc portion 152, and the apparatus can be configured to be thin and compact.

According to this, it is possible to prevent the fixed base 20 and the swivel base 30 from being separated by the disc portion 152. Since the rotating shaft 151 can rotate, it does not become resistance to the turning motion of the turntable 30. Further, when a load is applied on the swivel base 30, the central portion is bent. For this reason, it acts so that the contact part of the inner bottom face of the recessed part 161 and the upper surface of the disc part 152 may leave | separate, and it becomes less resistant to the turning motion of the turntable 30.
Moreover, according to the separation preventing means 150 described above, the structure is relatively simple and has a suitable function. In the present embodiment, the separation preventing means 150 is provided at the center of the apparatus, but the present invention is not limited to this. A plurality of them can be provided as appropriate.

Next, an embodiment in which the separation preventing means and the driving means are integrated will be described.
FIG. 6 is a cross-sectional view of the embodiment shown in FIG. 5 upside down (the fixed base 20 and the swivel base 30 are reversed) and the drive motor 65 is mounted on the lower side. The same reference numerals are given to the same components as those in the embodiment described above, and detailed description thereof will be omitted.
Reference numeral 151 denotes a rotation shaft, which is the rotation shaft of the drive motor 65. The lower surface of the disc part 152 and the inner bottom surface of the recessed part 161 are contacting. For this reason, when the disk portion 152 is rotationally driven through the rotation shaft 151 by the drive motor 65, the driving force is transmitted to the swivel base 30.

The swivel base 30 is regulated by the cooperation means 40 so as to be able to perform only a swivel motion that does not rotate. For this reason, by the transmission of the driving force, the swivel base 30 performs a turning motion that does not rotate.
Depending on the degree of connection between the lower surface of the disc portion 152 and the inner bottom surface of the recess 161, there is a difference in power transmission.
The greater the pressure contact force applied to both surfaces and the greater the slip resistance of each surface, the greater the frictional resistance and the easier the power is transmitted. In order to increase the pressure contact force applied to both surfaces, a biasing means such as a weight including the weight of the rotating shaft 151, an elastic member, a coil spring, and a leaf spring can be used. A magnet (magnetic force) can also be used.

According to this configuration, when an overload is applied to the drive motor 65, the lower surface of the disk portion 152 and the inner bottom surface of the concave portion 161 slip and the connection is separated. Therefore, it becomes escape at the time of overload, and the safety | security of an apparatus can be improved.
In addition, according to the present embodiment, since the separation preventing means and the driving means can be integrated, there is an effect that the configuration of the apparatus can be simplified and made compact.

  As the separation preventing means, in addition to the configuration described above, a first magnetic force means provided on the fixed base 20 and a second magnetic force provided on the swivel base 30 corresponding to the first magnetic force means. It is also possible to use suitably what comprises a means.

In the above embodiment, the first loop groove 41 and the second loop groove 42 are provided in the cooperation means 40, but the present invention is not limited to this. It is also possible to adopt a configuration in which a loop groove is provided only in one of the swivel base 30 and the fixed base 20.
For example, it can be set as the cooperation means of a structure as shown in FIG. Reference numeral 24 denotes a protruding portion, which is provided in a protruding shape on the surface of the fixed base 20 that faces the swivel base 30. Reference numeral 44 denotes a loop groove, which is provided in a groove shape on the surface of the swivel base 30 facing the fixed base 20 in a closed loop shape. The loop groove 44 is configured such that the protrusion 24 is fitted to guide the movement of the protrusion 24. It is also possible to provide the protruding portion 24 on the swivel base 30 and the loop groove 44 on the fixed base 20.

In the present embodiment, the protruding portion 24 is provided by a sphere (ball 45 a) accommodated in the accommodating portion 26. The accommodating portion 26 is provided with an open upper surface so that the inner spherical surface has a cross section of 180 ° or more, and is mounted on the fixed base 20. In the accommodating portion 26, the ball 45a is accommodated so that it can roll and does not come off. The upper spherical surface of the ball 45 a is exposed from the accommodating portion 26, and the upper spherical portion is fitted in the loop groove 44 of the swivel base 30. Thus, by using the ball 45a as a component of the protruding portion 24, friction can be further reduced. In addition, in order for the ball 45a to roll more smoothly in the accommodating part 26, it is also possible to employ | adopt a bearing structure.
Even with the cooperation means configured as described above, the swivel base 30 can perform a turning motion that does not rotate. However, the turning radius of the swivel base 30 depends on the size of the loop groove 44 and is the same as the turning radius of the protrusion 24 at the center of the ball. That is, the turning radius of the turntable 30 is smaller than that in the embodiment of FIG.

Next, an exercise apparatus using the swivel base device 10 according to the above embodiment will be described.
If the swivel base 30 of embodiment of FIG.1 and FIG.7 is utilized as a stand on which a person rides, it will become an exercise equipment. In particular, in the embodiment shown in FIG. 1, the sphere 45 rolls suitably, so that the swivel base 30 can turn very smoothly. Therefore, for example, when a person sits on the swivel base 30 and shakes his / her waist, a turning motion that does not easily change direction (does not rotate) can be obtained. Thereby, muscles, such as an abdominal muscle, can be gently trained.

Moreover, FIG. 8 shows an embodiment in which the swivel base device is used in a multistage manner for exercise equipment.
This exercise apparatus is provided in a state in which the swivel base device 10 described above is stacked in two stages. Reference numeral 20 denotes a fixed base, which corresponds to the lower stage of the two stages constituting the lowermost swivel base device 11. Reference numeral 30 denotes a swivel base, which corresponds to the upper stage of the two bases constituting the uppermost swivel base device 12. The upper surface of the swivel base 30 is provided as a part on which a person rides. Reference numeral 29 denotes an intermediate platform, which functions as a swivel base as the lowermost swivel base device 11 and functions as a fixed base as the uppermost swivel base device 12. That is, the function as the two stands is integrally provided in one intermediate stand 29.

Thus, according to the swivel base device in the state in which the swivel base device 10 is arranged in two stages, the swing width of the swivel base 30 can be increased. The maximum turning radius is doubled compared to a single stage.
In addition, since it has two stages, the degree of freedom of movement is expanded, and it is possible to start with a feeling that there is almost no static frictional resistance. Even if the force that triggers the movement is extremely light, the swivel base 30 can be moved. For example, when a person sits on the swivel base 30, the swivel base 30 starts to move very simply by moving the center of gravity of the person.

  Further, even in the swivel base device in such a two-stage state, the uppermost swivel base 30 performs a turning motion without changing its direction. This is a swivel movement in which neither the movement of the first stage or second stage swivel device 11 or 12 changes direction, and the movement of the swivel base 30 is a combination of the first and second stage movements. Because. The swivel base 30 can move at a maximum turning radius corresponding to the sum of the turning radii of the first and second turntable devices 11 and 12 at the maximum.

Further, the movement of the swivel base 30 is a combined movement of the first and second swivel base apparatuses 11 and 12, and depending on how the force is applied, the swivel base 30 can be complicated. Not only a simple non-rotating turning motion but also a linear motion is possible in some cases. That is, the swivel base 30 can move freely within a range within a plane having a fixed outer edge, which is the maximum turning radius. However, the swivel base 30 does not change its direction even in such a movement.
This movement that does not change the direction (movement that does not rotate) is a suitable vibration (wave) for humans (living organisms). Therefore, the exercise device of the present embodiment is also suitable as a health promotion tool. It can be used in a sitting or standing position.
Of course, the embodiment of FIG. 8 can be suitably used not only for exercise equipment but also for other devices that require turning motion. For example, it can be applied to a stirrer or the like as a multistage swivel device. Further, in this embodiment, there are two stages, but three or more stages may be used. The basic form of the single-stage swivel base device is thinned, and even if it is multi-staged, the dimension in the height direction is small and a stable apparatus can be provided.

Next, a swivel base device 13 according to another embodiment will be described with reference to FIG. FIG. 9A is a plan view of the swivel base device 13, and FIG. 9B is a cross-sectional view. In addition, about the structure similar to the above embodiment, the same code | symbol is attached | subjected and description is abbreviate | omitted.
In the present embodiment, the linkage means and the separation prevention means are constituted by a crank device (crank linkage mechanism 49).
Reference numeral 60 denotes a crank member, which includes a columnar first shaft 61 and a second shaft 62 whose axial centers are located in parallel at a predetermined distance, and the first shaft 61 is a first base ( A fixed base 20) is rotatably and non-detachably mounted, and a second shaft 62 is rotatably and non-detachably mounted on the second base (swivel base 30).

In addition, as shown in FIG. 10, the crank member 60 is equivalent in appearance to the shape formed when the end surfaces 64 are aligned with each other at the end surfaces 64 at right angles to the axis. In addition, the first shaft 61 and the second shaft 62 have the same diameter or a difference in radius between the first shaft 61 and the second shaft 62 that is smaller than the distance between the shaft centers. Also serves as a crank arm. Thus, since there is no independent crank arm part, the apparatus can be thinned.
The crank member 60 can be integrally formed by cutting (cutting). When the diameters of the first shaft 61 and the second shaft 62 are the same, the force can be suitably distributed and the balance is good. In addition, parts can be shared, such as using bearings with the same diameter.

Reference numeral 65 denotes a drive motor, which serves as a power source for relatively turning the first table and the second table. In the present embodiment, the swivel base 30 functions as a drive unit that generates power so that the swivel base 30 performs a swiveling motion with respect to the fixed base 20.
The drive motor 65 has a rotating shaft 66 fixed to the crank member 60. When the crank member 60 is turned by the rotational drive of the rotating shaft 66, the other crank member 60 is also driven and the turntable 30 is turned.

Further, in the crank device having the crank member 60 as a constituent element, it is possible to suitably obtain the function as the separation preventing means. FIG. 11 shows an example of the configuration. In addition, about the structure similar to the structure demonstrated based on FIG. 9, the same code | symbol is attached | subjected and description is abbreviate | omitted.
63 is a collar part, 67 is a cover plate, 68 is a bearing, 68a is a bearing fixing plate, and 69 is a screw. Both the first shaft 61 and the second shaft 62 are sandwiched between the flange portion 63 and the cover plate 67 and are pivotally attached to the fixed base 20 or the swivel base 30 via bearings 68. The bearing 68 is fixed to the fixed base 20 and the swivel base 30 via a bearing fixing plate 68 a and a screw 69. Further, the both shafts 61 and 62 are not separated from the fixed base 20 and the swivel base 30 by the screws 69 fixed in a state where the cover plate 67 is sandwiched between the centers (axial centers) of the first shaft 61 and the second shaft 62. It is configured as follows.
Thereby, the 1st axis | shaft 61 can be rotated with respect to the fixed base 20 with the cover plate 67, and the 2nd axis | shaft 62 can be rotated with respect to the turntable 30 with the cover plate 67, and can prevent separating.

Next, a swivel base device 14 according to another embodiment will be described with reference to FIG. 12A is a plan view of the swivel base device 14, and FIG. 12B is a cross-sectional view. In addition, about the structure similar to the above embodiment, the same code | symbol is attached | subjected and description is abbreviate | omitted.
In the present embodiment, the cooperation means and the separation prevention means are constituted by the sphere cooperation mechanism 40 a and the crank cooperation mechanism 49. That is, the cooperation mechanism 40 (sphere cooperation mechanism 40a) and the crank cooperation mechanism 49 of the embodiment of FIG. 1 and the embodiment of FIG. 9 are added together. The crank cooperation mechanism 49 functions as a separation prevention unit and also functions as a cooperation unit. Since the crank member 60 is formed thin, it can be mixed with the spherical body cooperation mechanism 40a and configured at the same time.

In this embodiment, five sphere cooperation mechanisms 40a and five crank cooperation mechanisms 49 are provided, but the number is not limited. If there are two or more in total, a turning motion of the turntable 30 that does not rotate can be obtained. If the total is 3 or more, stable exercise can be obtained. If the number of the spherical body cooperation mechanisms 40a is increased, a high load can be handled. Further, if the crank cooperation mechanism 49 is mainly used as a separation preventing means, the present invention is not limited to this embodiment, and an inferior strength may be used. Of course, the arrangement of the sphere cooperation mechanism 40a and the crank cooperation mechanism 49 can be selectively designed as appropriate.
Moreover, also in this form, it can utilize as an exercise device by providing the site | part which a person rides.

Next, a chair 70 in which a part of the exercise apparatus (swivel table device) on which a person rides is a chair seat will be described with reference to FIG.
FIG. 13 is a perspective view illustrating a chair using the swivel base device described above.
The fixed base 20 is fixed to the upper part of the leg portion 73. A handrail 71 and a backrest 72 are disposed on the fixed base 20, and the swivel base 30 is used as a seat in the form of a general office chair. A drive motor 75 is disposed on the lower surface of the fixed base 20 and drives the swivel base 30 to turn.
Further, the backrest 72 and the handrail 71 are fixedly disposed on the fixed base 20 so as not to hinder the turning movement of the turntable 30. The leg 73 has a height adjusting mechanism 74 shown in the drawing. Of course, not only the height adjusting mechanism 74 but also other known mechanisms can be used.

  The user sits on the swivel base 30 that is a seat, like a normal chair. Then, the swivel base 30 is swung and used as an exercise device. At this time, the user resists the turning motion of the swivel base 30 and tries to maintain the posture, so that the user can exercise using the muscles. In use, the user can lean on the handrail 71 or the backrest 72, and the burden on the body can be reduced. The backrest 72 and the handrail 71 may be fixedly disposed on the swivel base 30, but in this case, the user's head is swung along with the swivel movement of the backrest 72, and some people get drunk. . In this respect, when the backrest 72 and the handrail 71 are fixed to the fixed base 20, the swinging of the head can be suppressed, so that sickness can be prevented.

The exercise equipment having such a configuration is convenient because it is normally used as an office chair and can be used as an exercise equipment if necessary.
Furthermore, a human body detection switch 78 including a pressure switch or the like may be disposed in the approximate center of the upper surface of the swivel base 30. When the user sits on the swivel base 30, the human body detection switch may be activated, and the drive motor 75 may be started to turn the swivel base 30.

In such a chair 70, the user may directly control the turning motion of the swivel base 30 by using a start / stop switch for the drive motor 75 or a control switch for adjusting the rotation speed. These switches may be appropriately attached so that the user can easily operate them.
Further, a control device 80 may be provided. In the present embodiment, the control device 80 is attached to the outer surface of the drive motor 75, and the rotation of the motor rotation shaft is controlled. The control device 80 is provided with a plurality of different programs such as the rotation speed, rotation time, and rotation direction of the motor rotation shaft, and can control the rotation of the motor rotation shaft of the drive motor 75 according to the programs.
The start / stop switch of the drive motor 75, a control switch, or an operation panel for the user to select a program may be attached and fixed to a chair (swivel table device). It may be formed in a remote control type connected by wiring so that it can be operated. Of course, a cordless remote control is also suitable.

  The chair 70 having such a configuration is used as a kind of exercise equipment while sitting on the seat. When the user keeps the posture of the sitting state with respect to the turning motion, the user puts power into the body and exercises reflexively. This exercise is reflexive but uses muscles, so it can prevent muscle weakness. Such exercise is also effective as a pre-stage of walking training for people who have difficulty walking or standing. In addition, light exercise that improves blood flow in a relaxed state is effective for recovery from fatigue. In addition, the whole body exercise for burning body fat is performed, and there is a shape-up effect. In addition, this exercise helps to activate the intestinal function and has a dieting effect. It is also particularly effective for eliminating constipation.

In fact, when this chair was used by a patient with Parkinson's disease, the condition improved.
In addition, people with physical disabilities have been used by elderly people, and people who were unable to walk at all can now walk around several times.
Furthermore, in the case of a chair (bench) that can be used by 4 to 5 people, it can be enjoyed and exercise while having a conversation, so it has been well received by people who are bedridden or elderly people with physical disabilities.

Next, a bed, which is described above and is characterized in that a part of the exercise apparatus (swivel table device) on which a person rides is a part of the bed, will be described with reference to FIG.
FIG. 14 is a side view of a bed 81 that also serves as an exercise device using the swivel base device 10. The swivel base device 10 is equivalent to the embodiment described above, and the description thereof is omitted.
The bed 81 is formed by fixing the fixed base 20 of the swivel base device 10 on a fixed frame 82 and placing a cover base 83 on the swivel base 30. The user is located on the cover base 83 for use.

This is a type of exercise equipment because the part on which a person rides is bed-like, but does a rotation motion that does not rotate.
The cover base 83 is formed in a size that allows a person to take a supine posture. The user 28 is in a supine, recumbent or prone posture on the cover base 83, and uses the exercise equipment by turning the turntable 30. At this time, the user 28 reflexively applies force to the body in an attempt to maintain the posture with respect to the turning motion of the cover base 83, so that the muscles can be prevented from weakening. It is a suitable exercise for people who are particularly difficult to stand. Of course, instead of using the cover base 83, the swivel base 30 may be formed to have a sufficient size so that a person can take a supine posture, and the person directly gets on the swivel base 30.

  Furthermore, a bed as shown in FIG. 15 is also suitable as a bed for exercise equipment used in a supine posture. This is because the fixed base 20 of the swivel base device having the same configuration as that shown in FIG. 14 is extended to both sides of the cover base 83 (left and right direction in FIG. 15). The height of the extension 84 is substantially the same as the height of the cover base 83 or slightly higher than the height of the cover base 83.

The user 28 places the head and legs on the extension portion 84 and the torso portion on the cover base 83 and uses it as an exercise device in a supine or lying position.
If the bed is used in this way, the head and legs are not swung, so that even a user who is prone to getting sick with movement by a machine can prevent sickness. Further, since it can be partially swung around the lower back, it is also effective for treating low back pain and the like.
The size and height of the cover base 83 and the extension 84 may be set as appropriate according to the purpose of exercise. Of course, a handrail may be provided to prevent the user from falling from the bed.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments (first embodiment) relating to a swivel base device and exercise equipment of the present invention will be described below in detail with reference to the accompanying drawings.
FIG. 16 is a cross-sectional view of the swivel base device 510. FIG. 17 is a plan view of the swivel base device shown in FIG. The fixed base 514 is represented by a solid line, and the swivel base 511 is represented by a dotted line.
The swivel base device 510 is formed such that a fixed base 514 faces the swivel base 511 in parallel and four spheres (balls 512) are interposed therebetween. Further, the swivel base 511 and the fixed base 514 are connected by two connecting means for preventing separation.
Then, the swivel base 511 located above the stationary base 514 is relatively swiveled by the drive of the drive means. In the swivel base device 510, the upper surface of the swivel base 511 is a placement surface 526 on which an object is placed. Alternatively, the object is used by being fixed thereon.

The swivel base 511 and the fixed base 514 are made of metal, wood, plastic, or the like, and are formed in a substantially identical plate shape.
Four closed loop grooves (ball grooves 511a and 514a) are provided at positions corresponding to each other on the lower surface of the swivel base 511 and the upper surface of the fixed base 514, respectively.
The ball groove 511a and the ball groove 514a having substantially the same shape are formed in an annular shape, that is, a circle having a circular arc section (see FIG. 17).

  Then, the ball groove 511a of the swivel base 511 and the ball groove 514a of the fixed base 514 are opposed to each other, and the ball 512 is interposed one by one between them, and the swivel base 511 and the fixed base 514 are linked (connected). At this time, as shown in FIG. 15, the depth of the ball grooves 511 a and 514 a is preferably about 3/10 of the height (diameter) h of the ball 512. For this reason, when the ball 512 is inserted into the ball grooves 511a and 514a, about 4/10 of the height h of the ball 512 is preferably exposed between the swivel base 511 and the fixed base 514. .

As described above, the swivel base 511 and the fixed base 514 are arranged with the ball grooves 511a and the ball grooves 514a facing each other, and one ball is placed in each pair of the opposing ball grooves 511a and the ball grooves 514a. 512 is arranged. For this reason, the swivel base 511 can perform a swivel motion that draws a circle while maintaining a fixed orientation with respect to the fixed base 514. That is, it becomes possible to make a circular motion that does not rotate.
By making the sizes of the arcs of the cross-sectional circles of the ball groove 511a, the ball groove 514a, and the ball 512 substantially the same, the swivel base 511 is regulated by the ball grooves 511a, 514a and the ball 512, and is hardly rattled. , Swivel with respect to the fixed base 514.
In addition, the swivel base 511 and the fixed base 514 can be relatively swiveled.

A motor rotation shaft 519 a of the drive motor 519 placed on the swivel base 511 passes through the swivel base 511 and protrudes downward. That is, the swivel base 511 has a through hole, and the motor rotation shaft 519a protrudes downward from the through hole. And the drive gear 519b which has a tooth | gear on the outer side is being fixed to the front-end | tip part of the motor rotating shaft 519a.
On the other hand, the fixed base 514 is provided with a circular recess, and an internal gear 519c having teeth meshing with the drive gear 519b is formed on the inner periphery of the recess.
Then, when the swivel base 511 performs the above-described swivel movement with respect to the fixed base 514, the drive gear 519b rolls along the internal gear 519c. That is, by the rotational drive by the drive motor 519, the drive gear 519b rotates while revolving along the inner periphery of the internal gear 519c. Then, the swivel base 511 pivots relative to the stationary base 514 in a stationary state, and the four balls 512 roll in the ball grooves 511 a and 514 a as the swivel base 511 rotates.
At this time, the axis of the internal gear 519c and the axis of the motor rotating shaft 519a are arranged in an eccentric state with an eccentric distance g (both axes are parallel with a distance g). ). Further, the distance between the arc centers (pitch distance d) in the aforementioned ball grooves 511a and 514a is set to be the same as the eccentric distance g.

With the above-described configuration, the swivel base device 510 disposed so that the swivel base 511 performs a relative swiveling motion with respect to the stationary base 514 is stationary with the swivel base 511 by two separation prevention means (connection means). Separation from the fixed base 514 is prevented.
One of the two connecting means is a case 521. As shown in FIG. 16, the case 521 covers the upper surface of the swivel base 511 and is integrated with the swivel base 511, wraps around the lower surface of the fixed base 514, and sandwiches the fixed base 514 and the swivel base 511. The case 521 is integrated with the swivel base 511 and performs a swivel movement relative to the fixed base 514 without preventing the swivel movement of the swivel base 511. When a force acts so that the swivel base 511 and the fixed base 514 are separated from each other, the wraparound portion 521a on the outer edge of the case 521 presses the fixed base 514 toward the swivel base 511 so as to prevent the separation of both. Act on. Of course, the case 521 is provided in such a size as to allow the swivel movement of the swivel base 511 relative to the fixed base 514.
In addition, the cooperation means 40 mentioned above may be arranged between the surrounding part 521a of the case 521 and the fixed base 514 to improve the sliding.

The other connecting means is formed using magnet devices that attract each other. That is, the permanent magnet 522 is disposed on the upper surface of the fixed base 514, and the iron plate 523 is disposed on the lower surface of the swivel base 511 at a position facing the permanent magnet 522.
As a result, when the swivel base 511 and the fixed base 514 are combined to face each other, the permanent magnet 522 and the iron plate 523 are attracted, and the swivel base 511 and the swivel base 514 The fixed base 514 is connected.
In FIG. 17, a plurality (five) of permanent magnets 522 are arranged near the center of the fixed base 514.

As the driving means, a configuration as shown in FIG. 19 can be used. FIG. 19A is a sectional view of the drive means, and FIG. 19B is a perspective view of the crank part (drive shaft 513).
A motor rotation shaft 519 a of the drive motor 519 fixed to the swivel base 511 extends downward through a through hole of the swivel base 511. Then, the motor rotation shaft 519a and the drive shaft 513 are decentered by an eccentric distance equal to the pitch distance d of the ball grooves (the motor rotation shaft and the drive shaft are arranged so that the axes of the motor rotation shaft and the drive shaft are parallel by a distance d). The drive shaft 513 is pivotally supported on the fixed base 514 side so as to be rotatable about its axis. The drive shaft 513 is provided with a through hole into which the motor rotation shaft 519a is inserted, and is provided with a keyway. The drive shaft 513 and the motor rotation shaft 519a are connected by a key (not shown).
The drive shaft 513 is supported by a bearing 525 provided on the fixed base 514. As a result, the swivel base 511 turns by the rotational drive by the drive motor 519. Further, the motor rotation shaft 519a and the drive shaft 513 are both cylindrical, and both form a kind of crank member.

In contrast to the above configuration, the drive motor 519 may be fixed to the lower surface of the fixed base 514 and disposed below the swivel base device. In this case, the motor rotating shaft 519a extending upward through the fixed base 514 is eccentrically connected to the drive shaft 513 in the same manner as described above. Then, the drive shaft 513 is inserted into a bearing 525 disposed on the swivel base 511, and is disposed so as to be rotatable about the axis. According to this, since the drive motor 519 is fixed to the fixed base 514 and does not make a turning motion, it is advantageous to adopt this configuration when there is a space below the fixed base 514.
Also in the drive means having the above-described gear configuration, the drive motor 519 can be fixed to the lower surface of the fixed base 514, and the internal gear 519c can be provided on the swivel base 511 side.

Further, the motor rotation shaft 519a and the drive shaft 513 may be directly connected or may be connected via a crank arm or the like.
Then, the turning motion of the turntable 511 can be adjusted by rotating the motor rotating shaft in the reverse direction by controlling the rotation direction, speed, and the like of the motor rotating shaft, or by reducing or accelerating the rotation speed.

Next, the Example (2nd Example) which concerns on a turntable apparatus is described based on FIGS.
20A is a bottom view of the swivel base device 527, and FIG. 20B is a cross-sectional view thereof. FIG. 21A is a plan view of a connecting portion used for the separation preventing means (connecting means), and FIG. 21B is a cross-sectional view thereof. And FIG.21 (c) is sectional drawing of the connection means comprised by combining two connection parts. FIG. 22A is a plan view of the swivel base 524 and the fixed base 525 formed in substantially the same shape, and FIG. 22B is a bottom view when the swivel base and the fixed base are combined.

The swivel base 524 and the fixed base 525 made of a metal plate are formed in substantially the same shape (see FIG. 22A), and a substantially rectangular opening 528 is provided at the center. The opening 528 is formed with a widened portion 528a having a wide width at the center of the long side. Here, when the length of the long side is M and the width of the widened portion 528 is W, the length M of the long side is set larger than the width W.
A plurality (12 in FIG. 20) of through holes (through holes 529) are provided around the opening 528 of the swivel base 524 and the fixed base 525. Then, as shown in FIG. 20B, disc-shaped ball support portions (ball receiving portions 530) are respectively fitted and fixed in the plurality of through holes 529. One end surface 530b side of the ball receiving portion 530 extends outward in a bowl shape, and a flange portion 530a is formed. The flange portion 530 a is locked and fixed to the edge of the through hole 529.

In addition, annular ball grooves 511a and 514a similar to those described in the first embodiment are disposed on one end surface 530b of the ball receiving portion 530.
Thus, a swivel base 524 and a fixed base 525 in which a plurality of ball grooves 511 a and 514 a are disposed are formed, and the fixed base 525 is disposed below the swivel base 524 so as to face the swivel base 524 in parallel. Is done.
Then, the ball groove on the fixed base 525 side is made to face each of the ball grooves on the swivel base 524, and one ball 512 is interposed between each ball groove, and the swivel base 524 and the fixed base 525 are linked to each other. Is formed. At this time, the swivel base 524 and the fixed base 525 are connected so that the openings 528 arranged on both of them overlap each other. Further, the openings 528 are arranged so as to intersect with each other as viewed in a plan view in FIG. That is, both directions (arrows A and B) are orthogonal (90 ° different) directions.

Coordination (connection) between the swivel base 524 and the fixed base 525 is performed by a separation prevention means (connection means 532) having two connection members 533 (first connection member and second connection member) having the same shape. .
The connecting member 533 is made of a metal plate having the same thickness as the swivel base 524 and the fixed base 525, and is composed of standing piece portions 533j and connecting piece portions 533d that are bent at substantially right angles, and has a cross section in its entirety. It is formed in a U-shape (see FIGS. 21A and 21B).
A through hole 533b is formed in the center of the connecting piece 533d. A ball receiving portion 534 similar to that described above is fixed to the through hole 533b by providing a ball groove 534a on the bottom surface of the U-shaped recess.

Furthermore, the length L of the connecting member is set slightly smaller than the length M of the long side of the opening 28 of the swivel base 524 and the fixed base 525 and larger than the width W of the widened portion.
The length N of the connecting piece 533d is set slightly smaller than the width W of the widened portion.

The two connecting members 533g (second connecting member) and 533h (first connecting member) face each other's ball grooves 511a and 514a and interpose the ball 512 therebetween, and the planar shape becomes a cross shape. (See FIGS. 20 and 21 (c)). That is, the two connecting members are combined so that the bottom surfaces of the U-shaped recesses face each other and cross each other so as to form a cross.
The two coupling members 533g and 533h combined in this way are arranged so as to be parallel (see FIG. 20B) by the balls 512 interposed therebetween. That is, in the two connecting members, the connecting piece 533d of the connecting member 533g (second connecting portion) is aligned in parallel with the swivel base 524, and the connecting piece 533d of the connecting member 533h (first connecting portion) is fixed. They are arranged in the opening 528 of the swivel base 524 and the fixed base 525 so as to align with the base 525 in parallel. At this time, the end portions 533a of both standing piece portions 533j of the second connecting member 533g are brought into contact with the opening edge portion of the opening portion 528 of the fixing base 525 in contact with the outer surface of the fixing base 525, and the End portions 533a of both standing piece portions 533j of one connecting member 533h are brought into contact with and latched on the opening edge of the opening 528 of the swivel base 524 in contact with the outer surface of the swivel base 524.

  The connecting means 532 in which the balls are interposed and the two connecting members 533g and 533h are provided so as to be able to turn relative to each other, the opening 528 in which the turning base 524 and the fixing base 525 are arranged at the center. In addition to preventing the two from being separated, the one connecting member is capable of swiveling in conjunction with the relative swiveling movement of the swivel base 524 with respect to the fixed base 525.

  A specific method of assembling the connecting members 533g and 533h into the swivel base 524 and the fixed base 525 is as follows. The swivel base 524 and the fixed base 525 combined in a state where they are oriented in different vertical and horizontal directions (see FIG. 22B). Then, the two connecting members 533g and 533h are fitted into the opening 528 from the outside by aligning the length direction of the connecting members 533g and 533h with the long side direction of the opening 528, respectively. Then, the two connecting members 533g and 533h are opposed to each other in a cross shape, and both are simultaneously rotated by 90 ° with the ball 512 interposed between the ball grooves 511a and 514a. At this time, both end portions 533a of the two connecting members 533g and 533h are brought into contact with the outer surfaces of the swivel base 524 and the fixed base 525, and are latched. Since the widened portion 528a is gradually widened by forming the notch 528b, the connecting members 533g and 533h can be smoothly rotated.

As described in the first embodiment, this swivel base device can also be formed such that the swivel base 524 automatically turns by providing a drive motor.
For example, as in the first embodiment, a drive motor is disposed on the swivel base 524, and the drive gear fixed to the tip of the rotating shaft of the motor rotates while revolving within the internal gear on the fixed base 525 side. You may provide.
Further, the driving means described in FIG. 19 for the first embodiment can be used.

According to the swivel base devices 510 and 527 described in the above embodiments, since the ball supports the swivel while rolling in conjunction with the swivel movement of the swivel, even if a heavy object is placed on the swivel. A swivel motion can be performed satisfactorily. In addition, the ball has a simple structure but is strong, and the swivel can be swiveled well.
In addition, by increasing the number of ball grooves on the swivel base and the fixed base and increasing the number of balls disposed between them, the strength can be further increased and the area of the mounting surface of the swivel base can be increased. it can.
Furthermore, by reducing the diameter of the ball, the space between the swivel base and the fixed base is narrowed, and the swivel base device can be formed thinner.

Further, the load applied on the swivel can also be accommodated by changing the position where the intervening ball is disposed.
Furthermore, since the connecting means connects the swivel base and the fixed base without preventing the swivel movement, the swivel base and the fixed base are not easily separated. Therefore, it is possible to prevent the fixed base from being dropped and damaged by lifting the swivel base.
The annular ball groove may be provided on either the swivel base or the fixed base. That is, on the other side, a ball housing portion (ball housing portion) may be disposed without hindering the rolling of the ball in the ball groove on one side accompanying the swiveling motion of the swivel base. For example, the ball housing portion may have a spherically recessed shape in which the ball can be rolled.
In addition, the annular ball groove has a circular arc shape in cross section, but is not limited thereto. The cross section may be V-shaped.
The swivel base device according to the above-described embodiment is effective as a device that performs a turning motion by placing a heavy object on a relatively wide mounting surface. Examples of suitable applications include exercise equipment, health promotion equipment, agitators and the like.

Further, the swivel bases 511 and 524 described in the above embodiments may be directly used as a swivel base for the exercise equipment described below, but a cover plate is formed integrally on the swivel bases 511 and 524. It is good also as a swivel. Moreover, when using the case 521 for connection of 1st Example, you may use what was integrated with the case 521 as a turntable.
Furthermore, the swivel base device described in the above embodiments may be unitized by forming it in a small size, etc., and these may be combined in a plurality of planes so that one swivel base device can be swung. Of course.

Next, the Example (3rd Example) which concerns on an exercise device is described based on FIG.

Furthermore, the handrail 101 is fixed to one end surface of the cover base (the swivel base 311).

Using the exercise device 114, the user 28 can perform an exercise of swinging the swivel base 311 with the handrail 101. Since this movement has a limited turning movement range of the swivel base 311, the burden on the user 28 can be reduced as compared with the movement of pushing a pushcart with casters. Therefore, it is effective for people who can stand but have difficulty walking.
Furthermore, an exercise device may be used in a state where one or more people are seated on the turntable 311. Even a person who sits down without actively exercising exerts his / her strength to keep his / her sitting posture with respect to the swivel motion of the swivel base 311, thereby preventing muscle weakening.

Further, by arranging a large number of swivel base unit units 102 side by side, a bench-type exercise device for a large number of people having a swivel base 311 having a large area can be easily formed.
Of course, at least one of the plurality of swivel base device units 102 of the exercise equipment 114 may be provided with a drive motor so that the swivel swings automatically.

Next, the Example (4th Example) which concerns on a wheelchair is described based on FIG.
FIG. 24 is a side view of an exercise apparatus formed by incorporating a swivel base device that does not use a drive motor into a wheelchair. The exercise device 115 is a normal wheelchair that is moved by manually rotating two wheels 104, and a swivel base unit 102 is fixed on a seat portion 105.
That is, the fixed base 20 of the swivel base device unit 102 is fixed to the seat part 105 of the wheelchair, and the swivel base 30 is a seat of the wheelchair.

Further, transmission means for transmitting the rotational motion of one wheel 104 to the swivel base unit 102 is provided. Thereby, when the wheel 104 rotates, the swivel base 30 of the swivel base unit 102 turns on the wheelchair.
The transmission means can be composed of a roller 106 that contacts the wheel, a pulley and a belt, or a sprocket and a chain.
