Hereinafter, the best mode according to the swivel device and the exercise equipment 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 device 10 according to the present invention. FIG. 2 is a plan view illustrating the swivel device 10, and FIG. 3 is a plan view schematically illustrating the principle of the swivel motion of the swivel device 10.

 Reference numeral 20 denotes a fixed stand, which corresponds to the first stand or the second stand. Reference numeral 30 denotes a swivel table, which is disposed so as to face the fixed table 20, and corresponds to the second table or the first table. If a part where a person rides is provided on the swivel 30, it can be used as an exercise equipment. Reference numeral 40 denotes a linking means, and a plurality thereof are provided so that the fixed base 20 and the turning base 30 are linked to each other so that the turning base 30 performs a rotating motion with respect to the fixed base 20 without rotating. Reference numeral 50 denotes separation preventing means, which is provided so as to prevent the fixed base 20 and the swivel base 30 from separating from each other and to maintain the cooperative state.

Reference numeral 41 denotes a first loop groove, which is provided in a groove-like closed loop shape on a surface of the fixed base 20 facing the swivel base 30. Reference numeral 42 denotes a second loop groove, which is provided in a groove-like closed loop on the surface of the swivel 30 facing the fixed base 20 and is arranged corresponding to the first loop groove 41. Reference numeral 45 denotes a sphere, which can be rolled into 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 perpendicular to the plane in which the swivel 30 swings, the positional relationship between the fixed base 20 and the swivel 30 is such that the first loop groove 41 and the second loop groove 42 are different. Are shifted by the moving diameter of the sphere 45 so that they overlap through the sphere 45.

 The linking means 40 is configured with the first loop groove 41, the second loop groove 42, and the sphere 45 as constituent elements.

 In the present embodiment, the first loop groove 41 and the second loop groove 42 are formed by molding with a metal material in order to obtain strength, and are press-fitted into a main body formed of a resin material and fixed. You.

Since the linking means 40 is configured as described above, the sphere 45 rotates in the first loop groove 41 and the second loop groove 42 while rolling along the two grooves 41 and 42 while rotating. do. This situation 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.

21 is the center of the first loop groove, indicated by a dot. 22 in the sphere on the fixed base The trajectory of the heart, indicated by the dashed line. Reference numeral 31 denotes the center of the second loop groove, which is indicated by a dot. Numeral 32 denotes a trajectory of the center of the sphere on the swivel base, which is indicated by a two-dot chain line. Reference numeral 43 denotes a contact point, which is a point at which the trajectory 22 of the center of the sphere on the fixed base contacts the trajectory 32 of the center of the sphere on the swivel base. The arrow indicates the motion locus of the swivel (the center 31 of the second loop groove). R is the turning radius of the swivel 30. Also, the state when the sphere 45 has turned 180 ° is indicated by a dotted line.

[0020] As is apparent from this figure, the swivel base 30 turns with a turning radius R with respect to the stationary fixed base 20. At this time, the sphere 45 makes a circular motion with a radius half of the radius R. In addition, as compared with the diameter of the trajectory of the center of the sphere moving along the first loop groove 41 or the second loop groove 42, the turning diameter of the turntable 30 is doubled. Therefore, according to the linking means 40 of the present configuration, there is an effect that the turning motion can be suitably expanded.

 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 make a very smooth swivel movement.

[0021] If the number of the coordinating means 40 is more than three, it is possible to obtain a stable turning motion if the number is three or more. In the present embodiment, five units are provided, including those incorporated in the separation preventing means described later. In addition, as the number of the linking means 40 increases, the weight can be favorably supported in a well-balanced manner.

 Further, in the present embodiment, the first loop groove 41 and the second loop groove 42 are formed in the same and circular ring shape. The present invention is not limited to this. Even if the first loop groove 41 and the second loop groove 42 are formed in an oval closed loop shape, the force S can be obtained to obtain the same effect. Even in this case, there is no impulsive direction change that occurs in the case of linear swinging motion (reciprocating motion). In other words, in the case of a closed loop, a smooth kind of rocking motion can be obtained.

Next, the separation preventing means 50 will be described based on FIG. 1 and FIG.

The separation preventing means 50 is provided on at least one of the fixed table 20 and the swivel table 30 with a separation preventing section facing the surface of the other table opposite to the surface of the other table. It is in the form of having

 Reference numeral 25 denotes a first concave portion, which is an example of a first opening or a concave portion provided in the fixing base 20. Reference numeral 51 denotes a first bridge portion, which is provided so as to be bridged over the first concave portion 25. Reference numeral 35 denotes a second recess, which is an example of a second opening or a recess provided in the swivel 30. Reference numeral 52 denotes a second bridge portion, which is provided in the second recess 35 so as to be bridged in a direction crossing the first bridge portion 51. The second bridging portion 52 includes a separation preventing portion 54 facing a surface opposite to the surface of the first bridging portion 51 to which the swivel 30 faces. Conversely, a similar site (separation preventing portion 53) exists in the first bridge portion 51.

 Reference numeral 55 denotes a screw, which fixes the first bridge 51 to the fixed base 20 and the second bridge 52 to the swivel 30. 77 is a through hole, which is used when screwing the screw 55.

In the present embodiment, the separation preventing means 50 (separation preventing portions 53 and 54) is provided substantially at the center of the swivel device 10. Therefore, the swivel 30 having a good balance can move smoothly. This is because the separation prevention means 50 is located at the center, and various forces are easily dispersed in all directions. In addition, since it is located at the center, the separation preventing means 50 can be suitably incorporated and the thickness can be reduced.

 Further, in the present embodiment, the above-described cooperation means 40 is also incorporated in the separation prevention means 50. Regarding the linking means 40, the same reference numerals as those described above are assigned and the description is omitted. This also allows the swivel 30 to move smoothly. In this embodiment, all the linking means 40 including the linking means 40 provided in the separation preventing means 50 are arranged in the same plane. For this reason, the load can be suitably received, and the turntable device 10 can be suitably thinned. It is also suitable for applications such as a stirrer that has high stability due to its thinness.

It is needless to say that the separation preventing means 50 is not limited to one, and a plurality may be appropriately provided.

 Further, the first bridge 51 and the second bridge 52 may be formed in a rod shape so as to prevent the separation by the point contact between the rods. The shape of the two bridge portions 51 and 52 can be appropriately selected from a plate shape and a plate shape, a rod shape and a plate shape, and is not particularly limited.

In addition, as shown in FIG. 4, the opening or opening is provided only in one of the fixed base 20 and the swivel base 30. A recess may be provided and the two bridges are formed to intersect within the opening or recess to prevent separation. FIG. 4 is a cross-sectional view showing an embodiment of the separation preventing means. The same components as those in the above embodiment are denoted by the same reference numerals, and description thereof is omitted. An opening 25 a is provided on the fixed base 20. In a state of being bridged over the opening 25a, the first bridge portion 51 is fixed to the fixed base 20 at both ends. Note that the first bridge portion 51 may be formed integrally with the fixed base 20 as a part of the material forming the fixed base 20. Further, the second bridge portion 52 is fixed to a flat portion on the lower surface of the swivel 30 at both ends.

Next, another embodiment that works on the separation preventing means will be described with reference to FIG.

 FIG. 5 is a cross-sectional view showing the swivel device 110 in which the separation preventing means 150 is provided at the center of the device. The same components as those of the embodiment described above are denoted by the same reference numerals, and detailed description will be omitted.

 151 is a rotation axis. Reference numeral 152 denotes a disk portion, which is provided at the lower end of the rotary shaft 151 in a disk shape having a large diameter. The rotating shaft 151 and the disk part 152 are components provided on the swivel 30. The disk portion 152 is a separation preventing portion that faces the surface 20a opposite to the surface of the fixed base 20 facing the swivel base 30.

 The rotating shaft 151 is rotatably (rotated) mounted on the swivel base 30 via a bearing 154. Reference numeral 155 denotes a stopper, which is formed at the upper end of the rotary shaft 151 in a flange shape having a large diameter. This can prevent the rotating shaft 151 and the disk portion 152 from falling off.

 [0026] Reference numeral 160 denotes an opening through which the rotary shaft 151 passes. The opening 160 is formed in such a size that the turning motion of the rotating shaft 151 accompanying the operation of the turning table 30 is not hindered. The opening 160 allows the disk portion 152 to be positioned as a separation preventing portion.

 Reference numeral 161 denotes a concave portion, 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 disk portion 152, and the device 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 disk part 152. Since the rotating shaft 151 can rotate, it does not resist the swiveling movement of the swivel 30. Further, when a load is applied on the swivel 30, the center portion is bent. For this reason, the recess 16 The contact portion between the inner bottom surface of 1 and the upper surface of the disk portion 152 acts so as to separate from each other, and is less resistant to the turning movement of the turntable 30.

 Further, according to the above-described separation preventing means 150, the structure is relatively simple and has a suitable function. Further, in the present embodiment, the separation preventing means 150 is provided at the center of the apparatus, but is not limited to this. In addition, it is also possible to appropriately provide a plurality.

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 of FIG. 5 with the upside down (fixed table 20 and swivel table 30 reversed) and drive motor 65 mounted on the lower side. The same components as those of the above-described embodiment are denoted by the same reference numerals, and detailed description is omitted.

 Reference numeral 151 denotes a rotation shaft, which is a rotation shaft of the drive motor 65. The lower surface of the disk portion 152 and the inner bottom surface of the concave portion 161 are in contact with each other. Therefore, when the disk portion 152 is rotationally driven via the rotary shaft 151 by the drive of the drive motor 65, the driving force is transmitted to the swivel 30.

The turning table 30 is regulated by the coordinating means 40 so as to perform only a fixed turning motion without rotation. Therefore, the transmission of the driving force causes the swivel table 30 to perform a swiveling motion that does not rotate.

 Power transmission differs depending on the degree of connection between the lower surface of the disk portion 152 and the inner bottom surface of the recess 161.

 The greater the pressure applied to both surfaces and the greater the sliding 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 own weight of the rotating shaft 151, an elastic member, a coil spring, and a panel can be used. Also, a magnet (magnetic force) can be used.

According to this configuration, when an overload is applied to the drive motor 65, the lower surface of the disc portion 152 and the inner bottom surface of the concave portion 161 slip, and the connection is separated. Therefore, escape occurs at the time of overload, and the safety of the device can be improved.

 Further, 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 device can be simplified and compacted.

As the separation preventing means, in addition to the configuration described above, a first magnetic means provided on the fixed base 20 and a second magnetic means provided on the swivel base 30 corresponding to the first magnetic means are provided. 2 magnetic hands It is also possible to suitably use one having a step.

 In the above embodiment, the force at which the first loop groove 41 and the second loop groove 42 are provided in the linking means 40 is not limited to this. A configuration in which a loop groove is provided in only one of the revolving base 30 and the fixed base 20 is also possible. For example, it is possible to use a linking means having a configuration as shown in FIG. Numeral 24 denotes a protruding portion, which is provided on the surface of the fixed base 20 facing the swivel base 30 in a protruding manner. Reference numeral 44 denotes a loop groove, which is provided in a groove-like closed loop shape on the surface of the swivel base 30 facing the fixed base 20. The loop groove 44 is configured so that the protrusion 24 fits and guides the movement of the protrusion 24. It is also possible to provide the projection 24 on the swivel 30 and the loop groove 44 on the fixed base 20.

 In the present embodiment, the projection 24 is provided by a sphere (ball 45a) housed in the housing 26. The accommodation section 26 is provided with its upper surface opened so that the inner spherical surface has a cross section of 180 ° or more, and is attached to the fixed base 20. The accommodation portion 26 accommodates the ball 45a so that it can roll and does not come off. The upper spherical portion of the ball 45a is exposed to the housing portion 26, and the upper spherical portion is fitted in the loop groove 44 of the swivel 30. By using the ball 45a as a component of the protruding portion 24, friction can be further reduced. In order to allow the ball 45a to roll more smoothly in the housing 26, a bearing structure may be employed.

 Even with the cooperation means configured as described above, the swivel 30 can exert a force S for performing a swiveling motion without rotating. However, the turning radius of the swivel table 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 of the embodiment of FIG.

 Next, a description will be given of an exercise apparatus using the swivel device 10 according to the above embodiment.

If the swivel 30 of the embodiment shown in FIGS. 1 and 7 is used as a platform on which a person rides, it becomes an exercise device. In particular, in the embodiment of FIG. 1, since the sphere 45 rolls favorably, the turntable 30 can turn very smoothly. Therefore, for example, when a person sits on the swivel 30 and shakes his / her waist, it is possible to obtain a turning motion that does not easily change direction (does not rotate). You. Thereby, muscles such as abdominal muscles can be gently trained.

 FIG. 8 shows an embodiment in which the swivel device is provided in multiple stages and used for exercise equipment.

 This exercise equipment is provided in a state where the above-described swivel device 10 is stacked in two stages. Reference numeral 20 denotes a fixed stand, which corresponds to the lower stage of the two stages constituting the lowermost swivel unit 11. Reference numeral 30 denotes a swivel table, which corresponds to the upper table of the two tables constituting the uppermost swivel table apparatus 12. The upper surface of the swivel 30 is provided as a part on which a person rides. Reference numeral 29 denotes an intermediate table, which functions as a turntable as the lowermost turntable device 11, and functions as a fixed table as the uppermost turntable device 12. That is, the functions of the two tables are provided integrally in one intermediate table 29.

 [0036] According to the swivel device in the state in which the swivel device 10 has two stages, the swing width of the swivel device 30 can be increased. The maximum turning radius is doubled as compared with the case of one stage.

 In addition, the two stages increase the degree of freedom of movement, and the engine can be started with almost no static friction resistance. The swivel 30 can be moved even if the force that triggers the movement is extremely small. For example, when a person sits on the swivel base 30, the swivel base 30 starts moving very easily only by moving the center of gravity of the person.

 [0037] Further, even in the two-stage swivel table apparatus, the uppermost swivel table 30 makes a revolving motion without changing its direction. This is a swivel motion in which both the first and second turntable devices 11 and 12 do not change their direction, and the motion of the swivel 30 is a combination of the first and second turn motions. That's why. Then, the swivel base 30 can move at the maximum turning radius corresponding to the sum of the turning radii of the first and second turntable devices 11 and 12 at the maximum.

 [0038] The movement of the turntable 30 is a combined movement of the first and second turntable devices 11 and 12, and depending on how the force is applied, the turntable 30 can be moved in a complicated manner. In some cases, linear motion is also possible instead of simple rotation motion without rotation. That is, the swivel base 30 can freely move within a range of a maximum turning radius within a plane having a fixed outer edge. However, even in such a movement, the swivel 30 does not change its direction.

The motion that does not change the direction (the motion that does not rotate) becomes a suitable vibration (wave) for humans (creatures). Therefore, the exercise device of the present embodiment is also suitable as a health promotion device. You. It can be used in a sitting or standing position.

 It should be noted that the embodiment of FIG. 8 can of course be suitably used for other devices that require pivoting movement, rather than just exercise equipment. For example, the present invention can be applied to a stirrer or the like as a multi-stage swivel device. In the present embodiment, the number of stages is two, but may be three or more. Since the basic form of the one-stage swivel unit is thin, even if it is multi-stage, a stable device with a small dimension in the height direction can be provided.

Next, a swivel unit 13 according to another embodiment will be described with reference to FIG. FIG. 9 (a) is a plan view of the turning table device 13, and FIG. 9 (b) is a cross-sectional view. It is to be noted that the same components as those of the above embodiment are denoted by the same reference numerals, and description thereof is omitted.

 In the present embodiment, the cooperation means and the separation prevention means are constituted by a crank device (crank cooperation mechanism 49).

 Reference numeral 60 denotes a crank member, which includes a columnar first shaft 61 and a second shaft 62 in which the shaft centers are located parallel to each other at a predetermined distance, and the first shaft 61 is provided on a first base ( A second shaft 62 is rotatably and non-detachably mounted on the fixed base 20) and is rotatably and non-detachably mounted on the second base (the swivel base 30).

Further, as shown in FIG. 10, this crank member 60 has the same appearance as the shape formed when the cylinders whose end faces 64 are perpendicular to the axis are joined together by the end faces 64. is there. Further, the first shaft 61 and the second shaft 62 have the same diameter or the difference in radius between the two is smaller than the distance between the shaft centers, and the first shaft 61 and the second shaft 62 are different from each other. Also serves as the crank arm. As described above, since there is no independent crank arm portion, the thickness of the device can be reduced.

 The crank member 60 can be integrally formed by cutting (cutting). When the first shaft 61 and the second shaft 62 have the same diameter, the force can be appropriately dispersed, and the balance is good. In addition, parts can be shared, for example, bearings of the same diameter can be used.

[0041] Reference numeral 65 denotes a drive motor, which serves as a power source for relatively rotating the first table and the second table. In the present embodiment, it functions as a driving unit that generates power so that the swivel base 30 makes 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. Its rotation axis When the crank member 60 is rotated by the rotation drive of 66, the other crank members 60 are also driven and the swivel base 30 is rotated.

[0042] In the crank device including the crank member 60 as a constituent element, the function as the separation preventing means can be suitably obtained. FIG. 11 shows an example of the configuration. Note that the same components as those described with reference to FIG. 9 are denoted by the same reference numerals and description thereof will be omitted.

 63 is a flange, 67 is a cover plate, 68 is a bearing, 68a is a bearing fixing plate, and 69 is a screw. The first shaft 61 and the second shaft 62 are both sandwiched between the flange 63 and the cover plate 67, and are mounted on the fixed base 20 or the swivel base 30 via a bearing 68. The bearing 68 is fixed to the fixed base 20 and the swivel base 30 via a fixing plate 68a for bearing and a screw 69. Further, the screws 69 fixed to the center (axial center) of the first shaft 61 and the second shaft 62 with the cover plate 67 sandwiched therebetween do not separate the two shafts 61 and 62 from the fixed base 20 and the swivel base 30. It is configured as follows.

 Thus, the first shaft 61 can rotate with respect to the fixed base 20 together with the cover plate 67, and the second shaft 62 can rotate with respect to the swivel base 30 together with the cover plate 67, and can be prevented from being separated.

 Next, a swivel unit 14 according to another embodiment will be described with reference to FIG. FIG. 12 (a) is a plan view of the swivel device 14, and FIG. 12 (b) is a cross-sectional view. In addition, about the structure similar to the above-mentioned 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 40a and the crank cooperation mechanism 49. In other words, the embodiment has a configuration in which the cooperation mechanism 40 (the sphere cooperation mechanism 40a) and the crank cooperation mechanism 49 of the embodiment of FIG. 1 and the embodiment of FIG. 9 are added. The crank cooperation mechanism 49 functions not only as a separation preventing means but also as a cooperation means. Since the crank member 60 is formed to be thin, it can be configured simultaneously with the sphere linking mechanism 40a.

[0044] In the present embodiment, the forces provided with five sphere cooperation mechanisms 40a and five crank cooperation mechanisms 49, respectively, are not limited in number. If the total number is two or more, a turning motion of the turning table 30 that does not rotate can be obtained. If the total is three or more, stable movement can be obtained. Increasing the number of sphere linkages 40a allows The ability to respond S In addition, as long as the crank cooperation mechanism 49 is mainly used as the separation preventing means, the present invention is not limited to this embodiment, and a mechanism having poor strength may be used. In addition, the arrangement of the sphere linkage mechanism 40a and the crank linkage mechanism 49 can of course be appropriately and selectively designed.

 Also, in this form, it can be used as an exercise device by providing a portion where a person rides.

Next, a chair 70 characterized in that a part of the exercise equipment (turntable 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 device described above. The fixing base 20 is fixed on the upper part of the leg 73. A handrail 71 and a backrest 72 are provided on the fixed table 20, and the swivel table 30 is used as a seat to form a general office chair. A drive motor 75 is provided on the lower surface of the fixed base 20 and drives the swivel base 30 to rotate.

 The backrest 72 and the handrail 71 are fixed to the fixed base 20 so as not to hinder the swiveling movement of the swivel base 30. The leg 73 has a height adjusting mechanism 74 shown in the figure. It is needless to say that not only the height adjusting mechanism 74 but also other known mechanisms can be used.

The user sits on a swivel 30 which is a seat, similarly to a normal chair. Then, the swivel 30 is swung and used as an exercise device. At this time, since the user tries to maintain the posture by resisting the swiveling movement of the swivel base 30, the user can exercise using the muscles. In use, it can lean against the handrails 71 and the backrest 72, reducing the burden on the body. The backrest 72 and the handrail 71 may be fixedly provided on the swivel base 30, but in this case, the head of the user is swung by the turning movement of the backrest 72, and some people become drunk. I have. In this regard, when the backrest 72 and the handrail 71 are fixed to the fixing base 20, the swinging of the head is suppressed, so that sickness can be prevented.

[0047] The exercise equipment having such a configuration is usually used as an office chair, and can be used as an exercise equipment as needed, which is convenient.

 Further, a human body detection switch 78 such as a pressure switch may be disposed substantially at the center of the upper surface of the swivel 30. When the user sits on the swivel base 30, the human body detection switch may be operated, the drive motor 75 may be started, and the swivel base 30 may perform a swiveling motion.

[0048] In such a chair 70, the user operates a switch for starting and stopping the drive motor 75, The turning movement of the turntable 30 may be directly controlled by using a control switch for adjusting the rotation speed. These switches may be provided as appropriate so that the user can easily operate the switches.

 Also, it is acceptable to provide the control device 80. In the present embodiment, the control device 80 is provided on the outer surface of the drive motor 75, and controls the rotation of the motor rotation shaft. The control device 80 includes a plurality of programs having different rotation speeds, rotation times, rotation directions, and the like of the motor rotation shaft, and can control the rotation of the motor rotation shaft of the drive motor 75 in accordance with the programs. A switch for starting and stopping the drive motor 75, a control switch, or an operation panel for a user to select a program may be attached to a chair (turntable device) and fixed. It can be formed in a remote control type connected by wiring so that it can be operated with. Of course, a cordless remote controller is also suitable.

The chair 70 having such a configuration is used as a kind of exercise equipment by sitting on the seat. The user exerts force on his body to maintain a sitting posture in response to the turning motion, and exercises reflexively. This exercise is reflexive but uses muscles and can prevent muscle weakness. Such exercises are also useful as a pre-training step for people who have difficulty walking or standing. In addition, light exercise to improve blood flow in a relaxed state will be effective in recovering from fatigue. In addition, there is a systemic exercise to burn body fat, which has a shape-up effect. In addition, this exercise helps to stimulate gut activity and has a dieting effect. It is also especially effective for relieving constipation.

 [0050] Actually, when this chair was used by a patient with Parkinson's disease, the condition was improved.

 In addition, elderly people who were physically handicapped could use the power, and people who couldn't walk at all could use the power and use it many times before they could transmit and walk.

 In addition, chairs (bench) that can be used by four to five people together can be used to enjoy exercising while having a conversation, and were popular among bedridden people and the elderly with physical disabilities. .

[0051] Next, as described above, the part of the exercise equipment (turntable device) on which a person rides is a part of the bed. A description will be given of a bed according to the present invention based on FIG.

 FIG. 14 is a side view of a bed 81 which also functions as an exercise device using the swivel device 10. As shown in FIG. The turning table device 10 is equivalent to the above-described embodiment, and the description 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 mounting the cover base 83 on the swivel base 30. The user uses it by placing it on the cover stand 83.

 [0052] This is a force in which a part on which a person rides is a bed-like force.

 The cover base 83 is formed large enough to allow a person to take a supine position thereon. The user 28 is in a supine, recumbent, or prone position on the cover 83, and uses the exercise equipment by swiveling the swivel 30. At this time, the user 28 reflexively applies force to the body in order to maintain a posture against the swiveling movement of the cover base 83, and thus can prevent the muscle from weakening. This is a particularly suitable exercise for people who have difficulty standing. Of course, the swivel 30 may be formed large enough to allow a person to lie in a supine position without using a single hip 83, and a person may directly ride on the swivel 30.

[0053] Further, as a bed that is also used for exercise equipment used in a supine position, a bed as shown in Fig. 15 is also suitable. This is because the fixed base 20 of the swivel unit 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 equal to or slightly higher than the height of the cover base 83.

The user 28 puts the head and legs on the extension portion 84 and the torso portion on the cover stand 83 and uses the exercise device in a supine or recumbent position.

 If the bed is used in this manner, the head and legs are not swung, so that even a user who is easily sick of exercise by a machine can be prevented from getting sick. In addition, since it can be partially swung around the waist, it is also effective for treating back pain and the like.

The size and height of the cover 83 and the extension 84 may be appropriately set according to the purpose of the exercise. Of course, a handrail may be provided to prevent the user from falling off the bed. Example 1

 Hereinafter, embodiments (first embodiment) of the swivel device and the exercise equipment of the present invention will be described in detail with reference to the accompanying drawings.

 FIG. 16 is a cross-sectional view of the swivel device 510. FIG. 17 is a plan view of the swivel 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 device 510 has a fixed base 514 disposed parallel to and opposed to the swivel table 511, and is formed with four spheres (balls 512) interposed therebetween. The swivel table 511 and the fixed table 514 are connected by two connecting means to prevent separation. The swivel table 511 located above the stationary fixed table 514 is driven by the drive table. A relatively circling movement is performed by driving the means. In the swivel table device 510, the upper surface of the swivel table 511 is a mounting surface 526, on which an object is mounted. Or an object is fixed on it and used.

 [0056] The revolving base 511 and the fixed base 514 are made of metal, wood, plastic, or the like, and are formed in a plate shape having substantially the same shape.

 Four closed loop grooves (ball grooves 511a, 514a) are provided at positions corresponding to each other on the lower surface of the revolving base 511 and the upper surface of the fixed base 514, respectively.

 The ball groove 51 la and the ball groove 514 a having substantially the same shape are formed in an annular shape, that is, in a circular shape with a circular arc-shaped cross section (see FIG. 17).

 Then, the ball groove 51 la of the swivel base 511 and the ball groove 514 a of the fixed base 514 are opposed to each other, and the swivel base 511 and the fixed base 514 are linked (connected) with one ball 512 interposed therebetween. Let's go. At this time, as shown in FIG. 15, the depths of the Beaugette grooves 511a and 514a are formed to be about three-tenths of the height (diameter) h of the Beaugette 512. Therefore, when the ball 512 is fitted into each of the ball grooves 511a and 514a, it is preferable that the ball 512 be formed so as to be exposed between the swiveling base 511 and the fixed base 514 at about four-tenths of the height h of the ball 512.

[0058] As described above, the swivel table 511 and the fixed table 514 are disposed with the respective ball grooves 511a and the ball grooves 514a facing each other. Each of them has a ball 512 arranged thereon. For this reason, the swivel base 511 is opposed to the fixed base 514. It is possible to make a circular motion while maintaining a certain direction. In other words, it is possible to make a circular motion that does not rotate.

 By making the arcs of the cross-section circles of the Beau-Nore groove 511a, the ball groove 514a and the ball 512 approximately the same size, the swivel base 511 is regulated by the Beau-no-re groove 511a, 514a and Beau-no-reel 512 and almost plays. It makes a revolving motion with respect to the fixed base 514.

 Note that the swivel table 511 and the fixed table 514 are relatively rotatable.

[0059] The motor rotation shaft 519a of the drive motor 519 mounted on the swivel table 511 penetrates the swivel table 511 and protrudes downward. That is, the turntable 511 has a through hole, and the motor rotation shaft 519a protrudes downward from the through hole. Then, a driving gear 519b having teeth on the outside is fixed to the leading end of the motor rotating shaft 519a.

 On the other hand, the fixed base 514 is provided with a circular concave portion, and an internal gear 519c having teeth meshing with the driving gear 519b is formed on the inner periphery of the concave portion.

 When the revolving base 511 makes the above-described revolving motion with respect to the fixed base 514, the driving gear 519b is formed to roll along the internal gear 519c. In other words, the rotation of the drive motor 519 causes the drive gear 519b to revolve around the inner periphery of the internal gear 519c while rotating. Then, the swivel base 511 relatively rotates with respect to the stationary base 514 in a stationary state, and the four balls 512 roll in the ball grooves 511a and 514a with the rotation of the swivel base 511.

 At this time, the axis of the internal gear 519c and the axis of the motor rotating shaft 519a are arranged eccentrically with an eccentric distance g (the axes of both are parallel with a distance g) ). The distance between the centers of the arcs in the ball grooves 511a and 514a (pitch distance d) is set to be equal to the eccentric distance g.

With the above configuration, the swivel device 510 arranged so that the swivel table 511 performs a swiveling motion relative to the stationary fixed table 514 is provided by two separation preventing means (connecting means). Thus, separation between the swivel table 511 and the fixed table 514 is prevented.

One of the two connecting means is a case 521. The case 521 covers the upper surface of the swivel base 511 and is integrated with the swivel base 511 as shown in FIG. Then, the case 521 is connected to the swivel table 51 1 It is integrated with a swivel base 511 that does not prevent the swivel movement of the fixed base 514 and makes a swivel movement relative to the fixed base 514. When a force acts so that the swivel table 511 and the fixed table 514 are separated from each other, the wraparound portion 521a around the outer edge of the case 521 presses the fixed table 514 toward the swivel table 511 to prevent separation of the two. Act on. Needless to say, the case 521 is provided in a size that allows the relative rotation of the swivel table 511 with respect to the fixed table 514. Note that the aforementioned linking means 40 may be provided between the surrounding portion 521a of the case 521 and the fixed base 514 to improve the slip.

[0061] The other connecting means is formed using magnet devices that attract each other. That is, the permanent magnet 522 is provided on the upper surface of the fixed base 514, and the iron plate 523 is provided on the lower surface of the swivel base 511 opposite to the permanent magnet 522.

 Thus, when the swivel table 511 and the fixed table 514 are combined so as to face each other, the permanent magnet 522 and the iron plate 523 attract each other, and the swivel table 511 and the swivel table 511 that can prevent the swivel movement of the swivel table 511 with respect to the fixed table 514 are prevented. 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.

 [0062] As the driving means, a configuration as shown in Fig. 19 can also be used. FIG. 19 (a) is a cross-sectional view of the drive means, and FIG. 19 (b) is a perspective view of a crank part (drive shaft 513).

 The motor rotation shaft 519a of the drive motor 519 fixed to the swivel 511 extends downward through the through hole of the swivel 511. Then, the motor rotation shaft 519a and the drive shaft 513 are eccentric with an eccentric distance equal to the pitch distance d of the ball grooves (arranged so that the axes of both the motor rotation shaft and the drive shaft are parallel at a distance d). ) The drive shaft 513 is rotatably supported about the axis of the drive shaft 513 on the fixed base 514 side. The drive shaft 513 has a through hole into which the motor rotation shaft 519a is inserted, and has a key groove. 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. Thus, the swivel table 511 performs a swiveling motion by the rotational drive by the drive motor 519. Further, the motor rotation shaft 519a and the drive shaft 513 are both cylindrical, and form a kind of a crank member. [0063] Contrary to the above configuration, the drive motor 519 may be fixed to the lower surface of the fixed base 514 and provided below the turning base apparatus. In this case, the motor rotation shaft 519a extending upward through the fixing base 514 is eccentrically connected to the drive shaft 513 as described above. Then, the drive shaft 513 is inserted into a bearing 525 provided on the swivel base 511, and is provided so as to be rotatable around the axis. According to this, since the drive motor 519 is fixed to the fixed base 514 and does not perform 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 revolving base 511 side.

 The connection between 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.

 The turning motion of the turntable 511 is adjusted by controlling the rotation direction and speed of the motor rotation shaft by a control means (not shown) so as to rotate the motor in the opposite direction, to reduce the rotation speed or to increase the speed of rotation. it can.

 Example 2

 Next, an embodiment (second embodiment) of the swivel unit will be described with reference to FIGS.

 FIG. 20A is a bottom view of the swivel device 527, and FIG. 20B is a cross-sectional view thereof. FIG. 21 (a) is a plan view of a connecting portion used for separation preventing means (connecting means), and FIG. 21 (b) is a cross-sectional view thereof. FIG. 21 (c) is a cross-sectional view of a connecting means constituted by combining two connecting portions. FIG. 22 (a) is a plan view of a swivel base 524 and a fixed base 525 formed in substantially the same shape, and FIG. 22 (b) is a bottom view when the swivel base and the fixed base are combined. is there.

 The revolving base 524 and the fixed base 525 made of a metal plate are formed in substantially the same shape (see FIG. 22 (a)), and a substantially rectangular opening 528 is provided at the center. The opening 528 is formed with a widened portion 528a that widens at the center of the long side. Here, assuming that 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 to be larger than the width W.

In addition, around the opening 528 of the swivel table 524 and the fixed table 525, a plurality (12 in FIG. 20) Are provided (through holes 529). As shown in FIG. 20 (b), disc-shaped ball support portions (ball receiving portions 530) are respectively fitted into and fixed to the plurality of through holes 529. One end surface 530b of the ball receiving portion 530 extends outward in a flange shape, and a flange portion 530a is formed. This flange portion 530a is locked and fixed to the edge of the through hole 529.

Further, annular ball grooves 51 la and 514 a similar to those described in the first embodiment are provided on one end surface 530 b of the ball receiving portion 530.

 In this way, a swivel table 524 having the plurality of ball grooves 51 la and 514 a and a fixed table 525 are formed, and the fixed table 525 is opposed to the swivel table 524 below the swivel table 524 in parallel. The rooster is established by himself.

 Then, the ball groove on the fixed base 525 side is opposed to the ball groove on the side of the swivel base 524, and the swivel base 524 and the fixed base 525 are linked with each other with one ball 512 interposed therebetween. A device is formed. At this time, the revolving base 524 and the fixed base 525 are connected so that the openings 528 provided on the respective sides overlap. In addition, the openings 528 are arranged so as to intersect each other in plan view as shown in FIG. That is, both directions (arrows A and B) are orthogonal (different by 90 °).

[0068] Cooperation (connection) between the swivel table 524 and the fixed table 525 is performed by a separation preventing means (connecting means 532) having two connecting members 533 (a first connecting member and a second connecting member) having the same shape. Done by.

 The connecting member 533 is made of a metal plate having the same thickness as the revolving base 524 and the fixed base 525, and is composed of upright pieces 53 ° and connecting pieces 533d at both ends bent at substantially right angles. It has a U-shaped cross section (see FIGS. 21 (a) and 21 (b)).

 A through hole 533b is formed at the center of the connecting piece 533d. In this through hole 533b, the same ball receiving portion 534 force ball groove 534a as described above is provided on the inner bottom surface of the U-shaped concave portion and fixed.

[0069] Further, the length L of the connecting member is set to be larger than the width W of the widened portion slightly smaller than the length M of the long side of the opening 28 of the revolving base 524 and the fixed base 525.

The length N of the connecting piece 533d is set slightly smaller than the width W of the widened portion. [0070] The two connecting members 533g (second connecting member) and 533h (first connecting member) face each other with the ball grooves 511a and 514a facing each other and the ball 512 interposed therebetween. They are combined so as to form a cross (see Fig. 20 and Fig. 21 (c)). In other words, the two connecting members are combined such that the inner bottom surfaces of the U-shaped concave portions face each other and cross each other so as to form a cross.

 The two connecting members 533g and 533h thus combined are arranged so as to be parallel to each other (see FIG. 20 (b)) by a bow hole 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 turntable 524, and the connecting piece 533d of the connecting member 533h (first connecting portion) is provided. It is arranged in the opening 528 of the swivel base 524 and the fixed base 525 so as to be aligned in parallel with the fixed base 525, respectively. At this time, the ends 533a of the two upstanding pieces 533j of the second connecting member 533g abut on the opening edges of the opening 528 of the fixing base 525 by abutting on the outer side surface of the fixing base 525, and are locked. The ends 533a of the two upstanding pieces 53 の of the first connecting member 533h are engaged with the opening edges of the opening 528 of the turntable 524 by contacting the outer side surfaces of the turntable 524.

 [0071] A connecting means 532 provided with a ball interposed therebetween and capable of rotating relative to each other with two connecting members 533g and 533h in force S, has a turning table 524 and a fixed table 525 disposed in the center. One of the connecting members is capable of pivoting movement in conjunction with the relative pivoting movement of the swivel base 524 with respect to the fixed base 525 while being pinched by the opening 528 thus formed.

[0072] The specific method of assembling the connecting members 533g and 533h to the swivel base 524 and the fixed base 525 is as follows: the swivel base 524 and the fixed base 525 that are combined in the vertical and horizontal directions (see Fig. 22 (b)). 2), the two connecting members 533g and 533h are fitted into the opening 528 so that the length direction of the connecting members 533g and 533h is aligned with the long side of the opening 528 from the outside. Then, the two connecting members 533g and 533h are opposed to each other in a cross shape, and both are simultaneously rotated 90 ° with the ball 512 interposed between the ball grooves 51la and 514a. At this time, both ends 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 to be hooked. The widened portion 528a has a notch 528b and is gradually widened, so that the connecting members 533g and 533h can rotate smoothly. it can.

 [0073] As described in the first embodiment, this swivel base device can also be formed so that a drive motor is provided so that the swivel base 524 automatically performs a swiveling motion.

 For example, as in the first embodiment, a drive motor is provided on the swivel table 524, and the drive gear fixed to the tip of the rotating shaft of the motor revolves while revolving in the internal gear on the fixed table 525 side. It may be provided.

 Further, the driving means described in the first embodiment with reference to FIG. 19 can be used.

According to the swivel units 510 and 527 described in the above embodiments, since the ball supports the swivel while rolling in conjunction with the swiveling movement of the swivel, heavy objects can be placed on the swivel. Even if it is put, it is possible to make a good swing motion. In addition, the ball has a simple structure but is strong, and the swivel base can be swirled well.

 Also, by increasing the number of ball grooves on the swivel base and the fixed base, and by increasing the number of balls arranged between them, the strength can be further increased and the area of the mounting surface of the swivel base can be increased. it can.

 Further, by reducing the diameter of the ball, the space between the swivel base and the fixed base is narrowed, so that the swivel base apparatus can be formed thinner.
