When the cylinder is located in at least a part of the rotational region from the upper end through its downstream portion in the rotational direction to the lower end, the sliding means advances the piston rod outward, while the cylinder is located in the other rotational region. When the sliding means moves the piston rod and the piston inward. Then, the position of the center of gravity of the cylinder is radially outside in a part of the rotation regions with respect to the other rotation regions, so that a rotational force is generated in the disk. As a result, the disk is continuously rotationally driven. Therefore, if there is a main body device without using electricity or gasoline, it is possible to drive the rotation by itself, and it can be used at any time and place even in the event of a power failure or disaster. Further, by providing a power generation mechanism for the rotary drive device of the present invention, it can be used as a generator.
Further, a spring provided between the inner inner part of the cylinder and the piston applies a pressing force in the direction in which the piston rod advances. On the other hand, the outer frame provided over the entire other rotation region retracts the piston rod against the pressing force of the spring when the tip of the piston rod comes into contact with the outer frame. When the cylinder comes out of the outer frame as it rotates, the piston rod advances due to the spring, the position of the center of gravity of the cylinder changes, and the disk rotates.

In the case of the invention of claim 2, since an inclined surface capable of converting a part of the contact force into the retracting input of the piston rod is formed in the portion where the tip end portion of the piston rod comes into contact with the outer frame, the piston rod When the tip portion comes into contact with the outer frame, the piston rod can be smoothly retracted and retracted.

When the cylinder is located in at least a part of the rotational region from the upper end through its downstream portion in the rotational direction to the lower end, the sliding means advances the piston rod outward, while the cylinder is located in the other rotational region. When the sliding means moves the piston rod and the piston inward. Then, the position of the center of gravity of the cylinder is radially outside in a part of the rotation regions with respect to the other rotation regions, so that a rotational force is generated in the disk. As a result, the disk is continuously rotationally driven. Therefore, if there is a main body device without using electricity or gasoline, it is possible to drive the rotation by itself, and it can be used at any time and place even in the event of a power failure or disaster. Further, by providing a power generation mechanism for the rotary drive device of the present invention, it can be used as a generator.
Further, a spring provided between the inner inner part of the cylinder and the piston applies a pressing force in the direction in which the piston rod advances.

In this case, the piston rod can be reliably retracted by the outer frame, and the piston rod can be pushed further to the back side by the second magnet, so that the position of the center of gravity of the cylinder in the other rotation region is set to the disk as compared with the case of the outer frame. It is possible to move it closer to the center of gravity so that it does not come into contact with the outer frame, and the rotation can be made smoother. Further, since the outer frame can be used as a support member for the second magnet and the piston rod is reliably retracted by the outer frame, a magnet having a weak magnetic force can be used.

According to the invention of claim 5 , when the piston slides, the slide member slides in the same direction via the connecting spring. Therefore, when the piston rod retracts, the slide member slides in the same direction, and the disc pressing spring provided at the tip of the slide member comes into contact with the abutting portion of the disc to apply a rotational force to the disc. Therefore, a rotational force can be applied to the disk not only when the piston rod advances but also when the piston rod retracts, and the rotation of the disk can be made smooth. When the slide member is slid, the guided piece of the slide member is guided by the guide hole of the disk, so that the disk pressing spring can be reliably brought into contact with the disk contact portion.

In the case of the invention of claim 6, since the support piece extending in the slide direction of the piston is formed on the side opposite to the guided piece, which is the base end portion of the slide member, the base end portion of the slide member is formed. There is a guided piece and a supporting piece sandwiched between them, and the posture of the slide member can be stabilized.

(First Embodiment)
The first embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a front view schematically showing a rotary drive device according to the first embodiment, FIG. 2 is an exploded perspective view showing the rotary drive device, and FIG. 3 schematically shows a cylinder constituting the rotary drive device. It is a vertical sectional view.

The rotary drive device 1 is attached to a shaft 4 rotatably supported by a pair of support members 2 and 3 attached to a device body (not shown), a disk 10 attached to the shaft 4, and a wide surface 10A of the disk 10. The eight cylinders 11 are provided, a coiled spring 13 for advancing the piston rod 12 of the cylinder 11 outward, and an outer frame 14 for retracting the advanced piston rod 12 inward.

The shaft 4 is horizontally arranged by the support members 2 and 3, and the disk 10 can rotate integrally with the shaft 4 with the center of the shaft 4 as the axis. The rotation direction of the disk 10 is counterclockwise in FIG. 1, as will be described later. The shaft 4 does not have to be arranged horizontally, and may be arranged in an obliquely inclined direction.

The cylinder 11 is formed in a cylindrical shape having a rectangular cross section, one end side is closed, and the other end side is open. The opening 11A is narrowed, the piston 12A is contained inside, and the piston rod 12 connected to the piston 12A protrudes outward from the opening 11A. A spring 13 is arranged between the closed end side of the cylinder 11, that is, the inner inner wall 11B and the piston 12A, and the spring 13 causes the piston 12A to be on the inner edge of the opening 11A by elastic force. Make a contact. In this contacted state, the advance of the piston rod 12 is maximized (see FIG. 3).

Each cylinder 11 is arranged around the shaft 4 (the axis of the disk 10) so as to face the tip end portion 12B of the piston rod 12 toward the opposite side of the shaft 4 and to be separated from each other in the rotational direction (circumferential direction).
The arrangement position of each cylinder 11 will be described, for example, by taking the cylinder 11 in which the piston rod 12 faces upward in FIG. 1, as an example. Downstream in the rotational direction from the line segment E (dashed line) extending radially from the axis of the disk 10. The position is shifted to the side. This also applies to the other cylinders 11. The reason for this will be described later. Further, each cylinder 11 is formed to have a rectangular cross section including the piston 12A, the piston rod 12, and the like, but the present invention is not limited to this, and other cross-sectional shapes such as a circle may be used. However, the cylinder 11 preferably has a rectangular cross section in consideration of attachability to the disk 10.

The outer frame 14 is provided so as to cover the rotation region of the cylinder 11, that is, to face the rotation region, and the semicircular portion 14A having a constant radius of curvature and the inlet on the upstream side of the semicircular portion 14A in the rotation direction. It has a portion 14B and an outlet portion 14C on the downstream side in the rotation direction of the semicircular portion 14A. The semicircular portion 14A is provided from the lower end portion F facing the lower end of the rotation region of the cylinder 11 to the upper end portion G facing the upper end of the rotation region of the cylinder 11 via the portion facing the downstream side in the rotation direction. There is. The outer frame 14 is formed by, for example, bending molding of a strip-shaped plate or resin molding.

The semicircular portion 14A side of the inlet portion 14B and the outlet portion 14C is connected to the lower end portion F and the upper end portion G of the semicircular portion 14A, and the side opposite to the semicircular portion 14A of the inlet portion 14B and the outlet portion 14C is It is formed so that the distance from the rotation range of the cylinder 11 becomes longer as the distance from the semicircular portion 14A increases. The inlet portion 14B has an inlet 14D into which the tip portion 12B of the piston rod 12 that has advanced to the maximum is inserted without contacting the tip portion 12B, and the tip portion 12B of the piston rod 12 is brought into contact with the rotation of the disk 10 and thereafter. It is configured to be gradually retracted and sent to the semicircular portion 14A in a state of having a constant length. The semicircular portion 14A is configured to send the piston rod 12 to the outlet portion 14C in a state of having a constant length as the disk 10 rotates. The outlet portion 14C is configured so that the piston rod 12 is gradually advanced with the rotation of the disk 10, is brought into the maximum advanced state on the way, and is sent from the outlet 14E to the downstream side in the rotation direction.

The outer frame 14 and the spring 13 function as sliding means for sliding the piston rod 12 and the piston 12A.

(Principle of rotation)
Next, the principle of rotation of the rotation drive device will be described.
The piston rod 12 is in a state of being fully advanced when passing through the outlet portion 14C, and in that state, is sent to the downstream side in the rotational direction and enters the inlet portion 14B. Therefore, the piston rod 12 advances to the maximum from the middle of the outlet portion 14C to the middle of the inlet portion 14B, and the piston rod 12 retracts from the middle of the inlet portion 14B through the semicircular portion 14A to the middle of the outlet portion 14C. It will be in the entered state.

Therefore, the rotation region W1 from the upper end portion G of the outer frame 14 to the lower end portion F via the downstream portion in the rotation direction and the rotation region W2 from the lower end portion F to the upper end portion G via the downstream portion in the rotation direction. , The position of the center of gravity of the cylinder 11 changes as the piston rod 12 moves in and out. Specifically, in the rotation region W1, the position of the center of gravity thereof is radially outside the position of the center of gravity of the rotation region W2. The disk 10 is rotationally driven by this change in the position of the center of gravity. Therefore, if there is a main body device without using electricity or gasoline, it is possible to drive the rotation by itself, and it can be used at any time and place even in the event of a power failure or disaster.

If the length of the semicircular portion 14A is shorter than the rotation region W2, a portion where the piston rod 12 is advanced in the rotation region W2 will occur, and the rotational force of the disk 10 will drop. Therefore, the semicircular portion 14A requires a minimum rotation region W2.

Further, even if the semicircular portion 14A is slightly longer than the rotation region W2, in other words, even if the rotation region W1 is slightly shortened, the rotation of the disk 10 is not hindered. The reason will be explained below.

That is, the inlet portion 14B is necessary because without it, the piston rod 12 that has advanced to the maximum collides with the semicircular portion 14A and the disk 10 does not rotate. However, since the piston rod 12 moves in and out during the rotation, the state in which the piston rod 12 has advanced is reduced. On the other hand, with respect to the outlet portion 14C, even if this is omitted, there is not much hindrance to the rotation of the disk 10, but the piston rod 12 suddenly changes from the retracted state to the advanced state, and an impact is generated on the cylinder 11, which causes the disk. Since there is a possibility that it becomes difficult to obtain the smooth rotation of the 10, the piston rod 12 gradually advances, although the outlet portion 14C is necessary, so that the state in which the piston rod 12 has advanced is reduced. However, since the region where the advanced state of the piston rod 12 is reduced is the vicinity of the upper end G and the vicinity of the lower end F, it does not contribute much to the rotation of the disk 10. Therefore, the rotation region in which the piston rod 12 is advanced to the maximum can be set to the rotation region W3 which is slightly shorter than the rotation region W1.

One end of the rotation region W3 is a portion where the tip portion 12B of the piston rod 12 abuts on the inlet portion 14B, and the other end is a portion where the tip portion 12B of the piston rod 12 is separated from the outlet portion 14C.

Further, in the first embodiment, since the inclined surface 12C is formed at the portion where the tip portion 12B of the piston rod 12 comes into contact with the inlet portion 14B, the inclined surface 12C partially receives the contact force of the piston rod. Since it can be converted into the retreat input of, the piston rod 12 can be retreated smoothly.

Further, in the first embodiment, as described above, the arrangement position of each cylinder 11 is a position shifted to the downstream side in the rotation direction from the line segment E (dotted chain line) extending radially from the axis of the disk 10. (See Fig. 1). The reason is that the piston rod 12 abuts on the outer frame 14 so that the reaction force received from the outer frame 14 does not go toward the center of the disk 10 but toward the direction in which the disk 10 is rotated. By doing so, the rotational force of the disk 10 can be increased.

Further, in the first embodiment, eight cylinders 11 are arranged with respect to the disk 10, but the present invention is not limited to this. It is theoretically possible to rotate the disk 10 if the cylinder 11 to which the piston rod 12 has advanced is 1 or 2 or more in the rotation region W1. However, when there is one cylinder 11, since the rotational force is small when it is located at or near the lower end F of the rotation region, another cylinder 11 is required in the rotation region W1 and at least 2 in the rotation region W1. It is preferable to arrange so that more than one cylinder is located. As a result, the disk 10 is continuously rotationally driven.

Furthermore, in the first embodiment, the cylinder 11 is arranged on one side (wide surface 10A) of the disk 10, but the present invention is not limited to this, and the cylinder 11 is arranged on both sides of the disk 10. It may be installed. In this case, since the cylinder 11 has two rotation ranges, it is necessary to widen the width of the outer frame 14 (in the extending direction of the shaft 4) or increase the number of outer frames 14.

Furthermore, two or more disks 10 may be attached to a common shaft. In this case, two or more disks 10 having the same arrangement of cylinders 11 may be used, but two or more disks 10 having different arrangements of cylinders 11 may be used. As the discs 10 having different arrangements of the cylinders 11, it is preferable that the mounting position of the cylinders 11 is shifted in the circumferential direction in each disc 10. In this way, the timing at which the rotational force of the disk is generated can be increased, and smooth rotation can be obtained.

Furthermore, although the shape of the outer frame 14 in the width direction is not mentioned, both ends in the width direction (in the extending direction of the shaft 4) may be formed in a U-shaped cross section protruding toward the disk 10. In this way, the piston rod 12 can be reliably guided.

Furthermore, it can be used as a generator by attaching, for example, a magnet to a shaft 4 that rotates integrally with the disk 10 and arranging a coil around the rotating magnet. When used as a generator, for example, a coil may be attached to the rotating shaft 4, and magnets of N pole and S pole may be arranged on the outside thereof.

(Second Embodiment)
FIG. 4 is a front view for explaining the operation contents of the rotary drive device according to the second embodiment, and FIG. 5 is a vertical cross-sectional view schematically showing a cylinder constituting the rotary drive device. The same parts as those in FIGS. 1 to 3 are assigned the same numbers. Although FIG. 4 shows only three cylinders for convenience, eight cylinders are actually provided.

In this rotary drive device 1A, a first magnet 20 is provided at the tip portion 12B of the piston rod 12, and a plurality of second magnets 21 that repel the first magnet 20 are provided on the outer frame 24.

The tip portion 12B of the piston rod 12 is made of a non-magnetic material except for the first magnet 20, and the magnetism of the second magnet 21 acts on the first magnet 20. As the non-magnetic material, for example, hard resin, austenitic stainless steel, or the like is selected.

As described above, the outer frame 24 is provided with a plurality of second magnets 21, and the outer frame 24 is made of a non-magnetic material like the tip portion 12B of the piston rod 12. The second magnet 21 is provided so as to have the same polarity as the first magnet 20 so as to repel the first magnet 20, and if the second magnet 21 side of the first magnet 20 is, for example, an N pole, the first magnet 21 of the second magnet 21 is provided. The magnet 20 side is also N pole. Further, the second magnet 21 is integrally attached to the outer frame 24 so as to be flush with the inner peripheral surface of the outer frame 24, and the inner peripheral surface of the second magnet 21 and the outer frame 24 is a piston rod. There is no step on the axial side of the disk 10 so that the tip portion 12B of the 12 can slide smoothly. That is, the inner peripheral surface of the second magnet 21 is formed in an arc shape (only one second magnet 21 is shown in FIG. 5).

In the rotation drive device 1A, in the rotation region W2, the tip portion 12B of the piston rod 12 comes into contact with the outer frame 24, so that the piston rod resists the pressing force of the spring 13 as in the first embodiment. 12 retreats. In addition to this, there is a repulsive force between the first magnet 20 and the second magnet 21, so that the piston rod 12 further retracts. At this time, the repulsive force between the first magnet 20 and the second magnet 21 needs to be larger than the pressing force of the spring 13. With such a configuration, in the rotation region W1, the position of the center of gravity thereof is radially outside the position of the center of gravity of the rotation region W2. The disk 10 is rotationally driven by this change in the position of the center of gravity. This rotational driving force is larger than that of the rotational driving device 1 of the first embodiment because there is a repulsive force between the magnets. In this second embodiment, the first magnet 20 and the second magnet 21 that act on the repulsive force function as auxiliary rotation mechanisms that assist the rotation of the disk 10.

After that, when the tip portion 12B of the piston rod 12 comes off from the outlet portion 24C of the outer frame 24 due to the rotation of the disk 10, the piston rod 12 advances and is sent to the inlet portion 24B.

In the rotary drive device 1A, the sliding means for sliding the piston rod 12 is composed of a spring 13, a first magnet 20, an outer frame 24, and a plurality of second magnets 21.

In the rotary drive device 1A of the second embodiment configured in this way, since the repulsive force between the first magnet 20 and the second magnet 21 is used, the tip portion 12B of the piston rod 12 and the outer frame 24 are not removed. It becomes possible to make contact, and the rotation speed of the disk 10 can be increased. However, when the first magnet 20 approaches the second magnet 21, a repulsive force that hinders the rotation of the disk 10 is generated, so that the weight of the tip portion 12B of the piston rod 12 can be adjusted or the rotation of the disk 10 can be adjusted. It is preferable that the second magnets 21 are brought close to each other in order to suppress the repulsive force that interferes with the above, that is, a large number of second magnets 21 are provided as shown in FIG. In this case, it is desirable that the gap between the second magnets 21 is wider in the inlet portion 24B and the outlet portion 24C than in the semicircular portion 14A.

In the second embodiment, the second magnet 21 is supported by the outer frame 24, but the present invention is not limited to this, and the second magnet 21 is supported by another support member instead of the outer frame 24. You may try to do it. In this configuration, since the piston rod 12 retracts only by the second magnet 21, the frictional force between the tip portion 12B of the piston rod 12 and the outer frame 24 can be eliminated.

Further, the rotation of the disk 10 is performed, for example, by moving the second magnet 21 (or the outer frame 24) of the outer frame 24 in the extending direction of the shaft 4 (the axis of the disk 10), or the diameter from the disk 10 to the disk 10. It can be stopped by adopting a method such as moving it outward in the direction. In this case, when the rotation of the disk 10 is restarted, it is possible by returning the second magnet 21 (or the outer frame 24) to the original state, but the tip portion 12B of the piston rod 12 protrudes outward and the disk 10 If the rotation is stopped, there is a risk of collision with the second magnet 21 (or the outer frame 24) when the original state is restored. In order to prevent this, a plate material (not shown) made of a non-magnetic material having an arc shape that matches or substantially the same as the inner surface of the outer frame 24 is separately provided inside the outer frame 24 (on the disk 10 side) in a position-immobilized state. Is preferable.

Further, in the second embodiment, a large number of second magnets 21 are arranged, but the present invention is not limited to this, and an arc-shaped magnet in which all the second magnets 21 are integrated may be used. ..

(Third Embodiment)
A third embodiment of the present invention will be described with reference to the drawings.
6A and 6B are views for explaining the rotary drive device according to the third embodiment, FIG. 6A is a front view, and FIG. 6B is a bottom view of a main part. 7 is a vertical sectional view showing a cylinder constituting a rotary drive device, FIG. 8 is a perspective view showing a slide member and a cylinder constituting the rotary drive device, and FIG. 9 is a sectional view taken along line YY of FIG. 6 (A). 10 is a perspective view of the slide member and the disk as viewed from the Z direction of FIG. 6A. The same parts as those in FIGS. 1 to 3 are assigned the same numbers. Although one cylinder is shown in FIG. 6A for convenience, eight cylinders are actually arranged.

In the rotary drive device 1B, as in the first embodiment, the piston rod 32B moves in and out when it comes into contact with the outer frame 14, and the piston rod 32B comes off from the outer frame 14 and advances by the pressing force of the spring. In addition, as shown in FIG. 7, a through hole 31C is formed in a wall 31B opposite to the opening 31A of each cylinder 31, and the through hole 31C is inserted through the through hole 31C to form a connecting coil. One end 33A of the spring 33 is connected to the piston 32A, and the other end 33B of the coil spring 33 is connected to the slide member 34 as shown in FIGS. 6 and 8.

The slide member 34 is formed in a U shape and has a pair of extension pieces 34A and 34B and a connecting piece 34C between them. The other end 33B of the coil spring 33 is connected to the connecting piece 34C, and the extending pieces 34A and 34B extend in the thickness direction of the disk 10 (extending direction of the shaft 4). The disc pressing springs 35A and 35B are attached to the tip portions of the extension pieces 34A and 34B on the retracting direction side of the piston rod 32B. For example, a coil spring is used for the springs 35A and 35B, and the springs 35A and 35B are brought into contact with the contact members 36A and 36B provided on the disk 10 by the retracting of the piston rod 32B and separated by the advance of the piston rod 32B.

The slide member 34 is formed with guided pieces 37A and 37B protruding from the extension pieces 34A and 34B in the retracting direction of the piston rod 32B. As shown in FIGS. 6B and 10, guide holes 39A and 39B are formed on the abutting members 36A and 36B along the sliding direction of the sliding member 34.

Guided pieces 37A and 37B are inserted through the guide holes 39A and 39B, and the guided pieces 37A and 37B are guided by the guide holes 39A and 39B and slide. In FIG. 10, the guided pieces 37A and 37B are shown to come out from the guide holes 39A and 39B, but the guided pieces 37A and 37B are actually inserted through the guide holes 39A and 39B. Slide in the K direction.

Further, the slide member 34 is formed with support pieces 40A and 40B extending in the advancing direction of the piston rod 32B. As shown in FIG. 9, the support pieces 40A and 40B are slidably restrained by a pair of restraint pieces 41A and 41B provided on the disk 10. The restraint pieces 41A and 41B are formed in a key shape. These restraint pieces 41A and 41B function as restraint means. The restraining means is not limited to the key shape, and may have other shapes as long as the support pieces 40A and 40B can be slidably restrained.

In the case of the rotary drive device 1B, when the piston rod 32B retracts, the slide member 34 slides in the retracting direction of the piston rod 32B via the coil spring 33 connected to the piston 32A. At this time, the guided pieces 37A and 37B are guided by the guide holes 39A and 39B, and the support pieces 40A and 40B are restrained by the restraint pieces 41A and 41B and slide.

When the slide member 34 slides in the retracting direction of the piston rod 32B, the disc pressing springs 35A and 35B come into contact with the contact members 36A and 36B of the disc 10 and push the disc 10 in the rotational direction. That is, the mechanism using the slide member 34 functions as an auxiliary rotation mechanism that assists the rotation of the disk 10. As a result, the rotational force of the disk 10 is increased, and stable rotation of the disk 10 is maintained.

Therefore, a rotational force can be applied to the disk 10 not only when the position of the center of gravity changes due to the advance / retreat of the piston rod 32B but also when the piston rod 32B retreats, and the rotation of the disk 10 can be made smooth. When the slide member 34 is slid, the guided pieces 37A and 37B of the slide member 34 are guided by the guide holes 39A and 39B of the disk 10, so that the disk pressing springs 35A and 35B come into contact with the contact members 36A and 36B. Can be surely done. Further, since the guided pieces 37A and 37B and the support pieces 40A and 40B are supported by the guide pieces 39A and 39B and the restraint pieces 41A and 41B, respectively, the slide member 34 can slide without rattling and has a stable posture. Be retained.

On the other hand, when the piston rod 32B slides in the advancing direction, the springs 35A and 35B move away from the contact members 36A and 36B, so that the rotation of the disk 10 is not adversely affected.

In the third embodiment, the sliding means for sliding the piston rod 32B includes a connecting coil spring 33, a slide member 34, disk pressing springs 35A and 35B, contact members 36A and 36B, and a cover. It is composed of guide pieces 37A and 37B, guide holes 39A and 39B, support pieces 40A and 40B, and restraint pieces 41A and 41B.

Further, the slide member 34 is provided as a pair for the extension piece (34A, 34B), the disc pressing spring (35A, 35B), the guided piece (37A, 37B), and the support piece (40A, 40B). It may be provided by one or three or more. On the other hand, on the disk 10 side as well, the number of contact members (36A, 36B), guide holes (39A, 39B) and restraint pieces (41A, 41B) may be adjusted to match the number of the slide member 34 side.

In addition, the extension piece (34A, 34B), the connecting piece (34C), the guided piece (37A, 37B), the guide hole (39A, 39B), the support piece (40A, 40B) and the restraint piece (41A, 41B) Each cross-sectional shape is not limited to a rectangular shape. For example, it may be a circle, a triangle, a pentagon, a hexagon, or the like.

Further, the guide holes 39A and 39B may or may not penetrate the contact members 36A and 36B.

(Fourth Embodiment)
A fourth embodiment of the present invention will be described with reference to the drawings.
FIG. 11 is a view (front view) for explaining the rotation drive device according to the fourth embodiment, and FIG. 12 is a view showing the vicinity of the cylinder constituting the rotation drive device (the cylinder is a vertical cross-sectional view). .. The same parts as those in FIG. 1 are assigned the same numbers. Although FIG. 11 shows three cylinders for convenience, it is a state that is a main part of the operation content in this embodiment, and the actual number of cylinders is eight.

Similar to the first embodiment, the rotation drive device 1C of the fourth embodiment retracts when the piston rod tip portion 51B of the piston 51 abuts on the outer frame 14 in the rotation region W2, and the piston 51 in the rotation region W3. The piston rod tip portion 51B of the cylinder 50 is released from the outer frame 14 and advances by the pressing force of the spring to be rotationally driven. In addition, the piston 51 of the cylinder 50 is hollow and is connected to the hollow portion 51A. A float 53 having a lever 52 is provided, and a magnet 54 to be connected is provided on the outside of the cylinder 50.

The float 53 is provided on a part of the outer wall surface of the float 53 so that a plurality of rollers 51G facing the extending direction of the piston 51 and the cylinder 50 are in contact with the inner wall surface of the piston 51. A connecting magnet 52 is fixed to the inner wall surface of the float 53 and at a position corresponding to the roller 51G (although not shown, a rail that determines the direction of the roller 51G is provided on the inner wall surface of the piston 51. May be provided in). It is preferable that the hollow portion 51A is provided over the entire area of the piston 51 in order to secure a large buoyancy. The hollow portion 51A is filled with a liquid, for example, water 60. Therefore, when the piston rod tip 51B faces upward from the horizontal direction (H), the float 53 moves so as to approach the piston rod tip 51B side due to buoyancy, and when the piston rod tip 51B faces downward from the horizontal direction (H). I) The float 53 moves away from the piston rod tip 51B due to buoyancy. That is, the float 53 moves up and down depending on the direction of the piston rod tip portion 51B. At that time, the roller 51G enables smooth movement.

The cylinder 50 is provided with a thick portion 50C on the opening side opposite to the bottom portion. On the other hand, a stopper 51C is fixed to the piston 51 so as to cover the outer periphery of the piston 51 in the middle of the piston 51 in the axial direction. The enclosure stopper 51C should collide with the stepped portion 50B of the thick portion 50C when the piston 51 advances, but the impact absorbing spring 51D provided between the enclosure stopper 51C and the stepped portion 50B absorbs the impact. .. Further, a collision absorbing spring 13A for absorbing the collision with the float 53 is provided on the side of the piston 51 opposite to the piston rod tip portion 51B. Further, a ball retainer 51E is provided on the inner wall surface of the cylinder 50. The outer wall surface of the stopper 51 is in contact with the ball retainer 51E, which enables smooth movement when the piston 51 advances or retracts from the cylinder.

The magnet 54 to be connected is magnetically connected to the magnet 52 on the float 53 side via the wall of the piston 51 and the rollers 51F and 51G. Further, the magnet 54 to be connected is provided with a plurality of rollers 51F facing the stretching direction of the piston 51 and the cylinder 50 so as to be in contact with the outer wall surface of the piston 51 (although not shown, the orientation of the roller 51F). A rail or the like may be provided on the outer wall surface of the piston 51). As a result, the same movement as that of the connecting magnet 52 is smoothly performed according to the vertical movement of the float 53. The magnet 54 to be connected slides along the slit 50A provided in the cylinder 50 so that the magnetic force with the magnet 52 for connection can be strengthened because the thickness of the cylinder 50 is small. The slit 50A is formed in the axial direction of the cylinder 50. A slide gear 55 is attached to the magnet 54 to be connected, and the slide gear 55 also moves in the same manner as the magnet 52 for connection. The slide gear 55 is long in the direction in which the float 53 moves up and down, and the gear 55A is formed on the side opposite to the magnet 54 to be connected.

Near the bottom of the cylinder 50, a stop magnet 52A for stopping the slide gear 55 and the float 53 at predetermined positions by magnetic force is provided. The stop magnet 52A accumulates a buoyancy acting on the float 53 during a period from (I) when the tip portion 51B of the piston rod is downward in the horizontal direction until it is slightly upward, and the buoyancy is higher than the magnetic force. When it becomes large, the stopped state is released and the float 53 is provided so as to move vigorously toward the tip portion 51B of the piston rod.

The slide gear 55 meshes with the first gear 56 provided on the disk 10 within a predetermined slide range of the slide gear 55. A second gear 57 is attached to the shaft 59 of the first gear 56, and the first gear 56 and the second gear 57 are concentrically connected to each other. Further, the first gear 56 and the second gear 57 are rotatable with respect to the shaft 59, and the shaft 59 is supported by the disk 10. Further, the arcuate third gear 58 meshes with the second gear 57. The third gear 58 is supported by the device main body (not shown) of the rotary drive device 1C via a support member (not shown), is provided in an immobilized state, and has a gear on the inner peripheral surface side. 58A is formed. The center of curvature of the third gear 58 coincides with the axis of the disk 10 (the center of the axis 4), and the second gear 57 meshes with the third gear 58 within a predetermined rotation range as the disk 10 rotates. To do.

Therefore, when the disk 10 rotates and the piston rod tip portion 51B turns slightly upward from, for example, downward (I) to lateral (J), the float 53 begins to slide in the hollow portion 51A. That is, the float 53 approaches the piston rod tip 51B side from the state of being separated from the piston rod tip 51B. Along with this, the connecting magnet 52, the connected magnet 54, and the slide gear 55 move in the same manner as the float 53. Subsequently, the slide gear 55 meshes with the first gear 56 from the state (I) shown by the alternate long and short dash line shown in FIG. After that, when meshed, the first gear 56 and the second gear 57 rotate. Then, after the start of rotation, the second gear 57 approaches and meshes with the third gear 58 as the disk 10 rotates. The second gear 57 idles until it meshes with the third gear 58. Since the third gear 58 is supported and fixed to the main body of the device (not shown), the reaction force from the third gear 58 is transmitted to the shaft 59 provided on the disk 10. Since this reaction force acts on the disk 10 in the same direction as the disk 10 rotates, the rotational force of the disk 10 is increased. That is, the mechanism using the float 53, the slide gear 55, the first gear 56, the second gear 57, and the third gear 58 works as an auxiliary rotation mechanism that assists the rotation of the disk 10. At this time, since the second gear 57 has a larger diameter than the first gear 56, the peripheral speed is larger than that of the first gear, so that the rotation speed of the disk 10 can be further increased.

After that, before the float 53 rises to the maximum and before the state shown in FIG. 11 (H) is reached, the rear end of the slide gear 55 comes out of the first gear 56 and does not mesh with the second gear 57. Will come out of the third gear 58 and will not mesh. Both states can be selected. The reason is that when the float 53 rises to the maximum and the rotation of the first gear 56 and the second gear 57 stops, the rotation of the disk 10 stops when the second gear 57 and the third gear 58 are engaged. Because it will make you. Therefore, the third gear 58 is provided in a part of the rotation region W2 in which the float 53 receives the buoyancy from the liquid (water 60) and the piston rod tip portion 51B is in the process of advancing.

After that, before the second gear 57 comes out of the third gear 58 and returns to the third gear 58 by the rotation of the disk 10, the piston rod tip portion 51B faces downward and the float 53 is separated from the piston rod tip portion 51B. Even so, since the second gear 57 idles, there is no problem in the rotation of the disk 10.

In FIG. 12, the piston 51 is shown longer than the cylinder 50 (in the stretching direction), and even when the piston 51 retracts to the maximum extent, the tip of the piston 51 protrudes from the cylinder 50. The lengths of the cylinder 50 and the piston 51 may be adjusted so that the piston 51 fits in the cylinder 50 when the piston 51 retracts to the maximum extent.

In the fourth embodiment described above, the rotational drive may be stopped by causing the piston 51 to protrude from the outer frame 14.

The auxiliary rotation mechanisms described in the second to fourth embodiments described above may be used alone or in combination of two or more.

Further, in the first to fourth embodiments described above, the cylinder is attached to the wide surface of the disk, and the cylinder protrudes to the outside of the disk. However, the present invention is not limited to this, and the cylinder is inserted inside the disk. It is also possible to form a hole for use and insert a cylinder into the hole.

For example, with respect to the first embodiment and the second embodiment, a hole having a shape and a size in which the cylinder 11 can be inserted may be formed, and the cylinder 11 may be inserted into the hole. The third embodiment will be described by taking as an example a cylinder 31 in which the piston rod 51B faces to the right as shown in FIG. 13. A slit-shaped hole 70 extending from the outer peripheral surface of the disk 10 toward the vicinity of the axis is provided. The cylinder 31 and the slide member 34 formed on the disk 10 and having the configuration shown in FIG. 8 are inserted into the hole 70 with the extension pieces 34A and 34B facing up. The same applies to other cylinders.

Regarding the fourth embodiment, as shown in FIG. 14, a hole 71 for accommodating the slide gear 55, the first gear 56, the second gear 57, and the third gear 58 is provided in the disk 10. At this time, a wall 72 extending inward from the outer peripheral surface of the disk 10 is provided inside the hole 71, and a shaft 59 is formed on the wall 72 in parallel with the axis 4 of the disk 10. After that, the cylinder 50, the magnet 54 to be connected, and the slide gear 55 are inserted into the holes 71. In the arrangement of the cylinder 50, the magnet 54 to be connected and the slide gear 55, the magnet 54 to be connected is arranged on the rear side of the cylinder 50, and the slide gear 55 is arranged on the right side of the magnet 54 to be connected. The gear 55A of the slide gear 55 is directed in the direction opposite to the magnet 54. Shaft holes 59A of the integrated first gear 56 and second gear 57 are inserted into the shaft 59, and the first gear 56 and the second gear 57 are rotatably attached to the shaft 59. Some gears of the second gear 57 project outward from the outer peripheral surface of the disk 10. The protruding portion is configured to mesh with the third gear 58 supported by the device main body (not shown) by the rotation of the disk 10. The same configuration is used for other cylinders.

When the cylinder is arranged inside the disk 10 as described above, the rotation balance of the disk 10 can be improved, the rotation speed can be increased, and vibration, wind noise, and the like can be reduced.

Further, in the above-described first to third embodiments, the reduction of friction between the cylinder and the piston, between the cylinder and the piston rod, and between the piston rod and the outer frame is not mentioned. It is preferable to provide a rotatable ball, roll, or the like between the piston rod and the outer frame. Further, a guide roller for guiding the tip end portion of the piston rod to the inlet portion 14B may be provided on the upstream side of the inlet portion 14B, or the inlet portion 14B may be formed by the guide roller. Further, it is preferable to provide a ball retainer, a roller retainer, a rotatable ball, a roll, or the like between the cylinder and the piston, and between the cylinder and the piston rod (the fourth embodiment is the piston and the float). Although it is mentioned between the above and the like, it is assumed that the ball retainer, the roller retainer, the rotatable ball and the roll, etc. can be changed as appropriate.

The present invention relates to a rotary drive device that does not require electricity, gasoline, or the like and can be rotationally driven only by the main body.
