Abstract

PURPOSE:To dispose drive rails almost perpendicularly even at corner portions so as to enable a moving body moving along the driving rails disposed on the ceiling of the room of a building to smoothly run by disposing on the upper portion of the moving body a drive runner which is capable of rolling and rotating. CONSTITUTION:When the photoelectric tube 46 of a partition panel 1 senses light from the side of the wall of a garage a running motor 2 is rotated and rotation is transmitted from the motor 2 to rotary shafts 6a, 6b to a vertical shaft 14 to the driving roller 23 of each drive runner 18. The partition panel 1 is then displaced in a predetermined direction. When the panel reaches to a corner a rear drive runner 18 is almost stopped and a front drive runner 18 advances while changing its direction of movement. When the rear drive runner 18 comes to a corner the front drive runner 18 is almost stopped and the rear runner 18 advances. Thereby rails can be disposed almost perpendicularly at corner portions and so can be easily laid.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is a device that is suspended from a rail installed on the indoor ceiling of a building via a runner, and moves along the rail to reach a desired indoor space. The present invention relates to partition panels that can be partitioned at different positions to enable multipurpose use, and drive mechanisms for moving objects such as cranes for transporting goods in factories.

[Conventional technology]

Conventionally, as a drive mechanism for a partition panel, a runner is rotatably engaged with a ceiling rail, the partition panel is suspended from the runner, and a drive motor is used to rotate the runner within the partition panel. There is a known mechanism in which a partition panel is moved in a predetermined direction by rolling a runner along a ceiling rail based on the rotation of this drive motor (Japanese Patent Laid-Open No. 60-98081).

In this mechanism, a runner is integrally formed at the upper end of a vertical shaft protruding above the partition panel and rotates around the vertical shaft, and the vertical shaft passes through the bottom of the runner. An auxiliary runner rotatably held by the runner is provided, and the ceiling rail is divided into a runner running section and an auxiliary runner running section, the runner runs on the runner running section, and the runner is provided below the runner. The auxiliary runner runs on the auxiliary runner running section.

Additionally, cranes normally travel in a straight line, and can be moved around curved sections using a mechanism consisting of a rack and pinion.

[Problems to be Solved by the Invention] However, in the drive mechanism of the conventional partition panel described above,
Since there is no special mechanism for running around corners, running around corners is not smooth, and ceiling rails at corners are usually formed in an R shape and not at a right angle. There were problems in that construction was difficult, there were restrictions on where the rails could be installed, and the appearance was poor.

Further, since cranes usually travel in a straight line, a mechanism for moving corners has not been sufficiently studied, and there are problems similar to those described above.

The objects of the present invention are to enable smooth and quick running at corner sections, to enable easy construction by arranging rails at corner sections at almost right angles, to have fewer restrictions on where the rails can be installed, and to have a good appearance. The object of the present invention is to provide a drive mechanism for a movable body that is held by a user.

[Means to solve the problem]

In order to solve the above-mentioned problems, in the first invention, a drive rail is formed on the upper part of the movable body so as to be able to roll along a drive rail provided above the movable body to move the movable body. A pair of drive runners are provided and the drive runners are connected to a rotational drive source within the moving body via a differential device.

Further, in the second invention, below the drive runner,
A means of disposing a support runner that supports a moving body and is movable along a support rail, and interposing a rotatable connecting shaft between the support runner and the drive runner. is adopted.

Furthermore, in a third invention, the drive runner is formed to be able to rotate around a support shaft that supports the movable body and is rotationally driven, and a drive roller that rolls on the support shaft and the drive rail. In addition to having a driving force transmission mechanism between the
A means is adopted in which a driven roller is provided at a position facing the driving roller and freely rotates without being connected to a driving force transmission mechanism.

[Effect]

By employing the above means, in the first invention, the pair of drive runners disposed on the upper part of the movable body roll along the drive rails, so that the movable body moves, and at this time, the drive runners is connected to the rotational drive source inside the moving body via the differential, so if a force is applied to either drive runner at a corner in the direction of stopping it, the differential will evenly distribute the load. Therefore, the other driving runner rotates correspondingly faster, and as a result, the movable body can move smoothly around the corner.

Further, in the second invention, the drive runner moves along the drive rail, and the support runner supported below supports the movable body and moves along the support rail. When the body moves, the connecting shaft connected between the support runner and the drive runner rotates at the corner, allowing the movable body to move smoothly and forming the support rail almost at right angles. is possible.

Furthermore, in the third invention, the movable body moves as the drive runner rolls on the drive rail, and the drive runner turns at the corner of the drive rail to change direction in a predetermined direction. Therefore, the moving body can change direction almost at right angles and move.

[First Embodiment] An embodiment in which the present invention is embodied in a self-propelled drive mechanism for pulling a partition panel will be described below with reference to FIGS. 1 to 8.

As shown in Figure 1, the length is about 10 meters, the width is about 1 meter, and the thickness is 10 meters.
A running motor 2 as a rotational drive source is installed in the upper part of the partition panel l as a moving body extending in the vertical direction of several cm.
is arranged, and is rotated by being electrically connected to a battery 3 fixed to the center right side of the partition panel 1 through a lead wire 4. A differential device 7 is disposed above the traveling motor 2 to distribute the rotational force of the rotating shaft 5 of the traveling motor 2 to two rotating shafts 6a and 6b orthogonal thereto.

This differential device 7 will be explained. As shown in FIG. 2, a bevel gear 8 is integrally formed at the tip of the rotating shaft 5 of the traveling motor 2, and the bevel gear 8 connects two rotating shafts extending in a direction perpendicular to the rotating shaft 5. It meshes with a bevel gear 10 that is integrally provided in the case 9 that rotates around 6a and 6b. Inside this case 9, a support shaft 12 extending in a direction perpendicular to the rotating shafts 6a and 6b is supported in a support hole 9a of the case 9, and at both ends of the support shaft 12 are bevel gears 11a,
llc is rotatably supported. In addition, the rotating shaft 6a
A bevel gear lid is attached to the end of the rotating shaft 6.
A bevel gear 11b is attached to the end of b, and meshes with the bevel gears 11a and llc, respectively.

When the traveling motor 2 rotates, the case 9 rotates via the rotating shaft 5 and the bevel gears 8 and 10, and at the same time the bevel gears 11a and llc rotate, and these 11a and llc mesh with the bevel gears 11b and lid. Therefore, the rotating shafts 6a, 6
b rotate in the same direction.

An open clutch mechanism 55 is provided approximately in the center of the rotating shaft 6b, and one end of an operating rod 56 extending in the horizontal direction is attached to the lower end of the open clutch mechanism 55, and the other end of the operating rod 56 is attached to the lower end of the open clutch mechanism 55. is exposed at the end face of the partition panel l and serves as a clutch hole 57. Then, when an operating handle (not shown) is inserted into the clutch hole 57 and rotated, the release clutch mechanism 55 shuts off both sides of the rotating shaft 6b. Therefore, at this time, in the differential device 7, no load is applied to the rotating shaft 6b, so that the rotating shaft 6a can also rotate freely. As a result, partition panel 1
You can move it by pushing it with your hand.

As shown in FIG. 1, disk-shaped support runners 13 are disposed above the front and rear (left and right in the figure) of the partition panel l.
A vertical shaft 14 is rotatably inserted and supported in the center of the support runner 13. The lower part 4 of this support runner 13
A support roller 15 for supporting the partition panel 1 is rotatably supported at this location. A bevel gear 16 is attached to the lower end of the vertical shaft 14, and the bevel gear 16 meshes with bevel gears 17a, 17b attached to the tips of the rotating shafts 6a, 6b extending in the horizontal direction. ,6
The rotation of b can be transmitted to the vertical shaft 14.

A drive runner 18 for moving the partition panel 1 is arranged above the support runner 13, one end of which is rotatably supported on the upper end of the vertical shaft 14, and the other end supported by the drive runner 18. The drive runners 18 are connected to each other by a connecting shaft 19 that is rotatably supported at the lower end of the drive runner 18, and rotational force is transmitted to the drive runner 18 by the connecting shaft 19.

Here, the connection shaft 19 will be explained. As shown in FIGS. 6 to 8, this connecting shaft 19 consists of an upper connecting shaft 20 and a lower connecting shaft 21, and the lower end of the lower connecting shaft 21 is pinned in a direction perpendicular to the upper end of the vertical shaft 14. The upper end of the upper connecting shaft 20 is also connected to the lower end of the rotating shaft 24 of the drive port 23 (to be described later) of the drive runner 18. By inserting a pin in a direction orthogonal to the parts, a universal joint 25 is formed that can rotate freely in each direction.

The upper connecting shaft 20 is formed into a cylindrical shape having a hexagonal hole (not shown) bored in the shape of a hexagonal column, and a lower connecting shaft 21 formed in a hexagonal column shape is slidably inserted therethrough. Also,
A pair of elongated holes 27 that are long in the vertical direction are provided in the center of the upper connecting shaft 2o, a circular hole 28 is provided in the upper end of the lower connecting shaft 21 on the negative side, and the support pin 29 is inserted into these elongated holes. 27 and the hole 28. The lower end of the upper connecting shaft 20 becomes a flange portion 30 with an enlarged diameter, and there is a space between the flange portion 3° and an annular spring receiver 31 that is fitted onto the upper connecting shaft 20 at a lower position of the support pin 29. A coil spring 32 is interposed.

When the lower connecting shaft 21 moves downward to separate from the upper connecting shaft 2o, the support pin 29 moves downward within the elongated hole 27, and the coil spring 32 is compressed, thereby preventing the force that tries to move it downward. The lower connecting shaft 21 is missing.
When the support pin 29 moves upward to return to its original position, the support pin 29 is inserted into the long hole 2.
7, the coil spring 32 stretches and returns to its original state.

As shown in FIGS. 1 and 5, rollers 33 are rotatably supported at four locations on the lower part of the drive runner 18 and roll on the drive rail 34, and rollers 33 are rotatably supported at four locations on the lower part of the drive runner 18 and roll on the drive rail 34, and the rollers 33 are mounted on the upper part based on the rotation of the connecting shaft 19. A drive roller 23 that moves the drive runner I8 while pressing the wall 34a of the drive rail 34 is rotatably supported. Further, on the side opposite to the drive roller 23, a roller 35 is rotatably supported, which is pressed by a spring 53 and rotates in contact with the wall 34b of the drive rail 34.

The drive roller 23 of the drive runner 18 is installed at a low position on the left side in Figure 1, and at a high position on the right side in Figure 1, but this is because when the drive rail 34 is branched, The guide rails (not shown) provided on the rails 34 are used to guide the guide rails to separate rails. Further, the support roller 15 is connected to the drive rail 34.
The partition panel 1 is designed to roll on a support rail 36 provided at the lower part of the partition panel 1 while supporting the partition panel 1.

An operating shaft 37 extending in the horizontal direction is rotatably supported in the lower part of the partition panel 1, and a resection motor 38 is attached to the lower end (left end in FIG. 1) of the operating shaft 37. A shaft hole 39 for manual handle operation is bored at the end.

A diamond-shaped vertically movable member 40 is supported on the operating shaft 37 so that it can move in opposite directions relative to the operating shaft 37 at left and right opposing portions. It is possible to move.

The lower end of a picking lifting shaft 41 extending in the vertical direction is integrally attached to the upper end of this vertically moving member 40, and the upper end of the floor lifting shaft 41 extends its length to the upper end surface of the partition panel l. It is attached to the lower part of a rubber extraction cushion 43 extending in the direction. Further, the upper end of a floor-contacting lifting shaft 44 extending in the vertical direction is integrally attached to the lower end of the vertically movable member 40, and the lower end of the flooring-floor lifting shaft 44 extends along the lower end surface of the partition panel l. Also made of rubber floor cushion 45
is attached to the top of the

Then, by operating the extraction motor 38 or a manual handle (not shown), the upper end of the vertically movable member 40 moves upward and the lower end moves downward, and the extraction cushion 4
3 is in contact with the ceiling, and the floor cushion 45 is in contact with the floor to ensure shielding between the rooms on both sides of the partition panel 1.

A partitioning phototube 46 is attached to the upper left part of the surface of the partitioning panel 1 (the surface on the near side in FIG. 1), and a starting floodlight tube is provided at an opposing position. When the light hits the vehicle, the traveling motor 2 rotates. A reflective travel stop phototube 47 is attached to the upper part of the left end surface of the partition panel l, so that the travel motor 2 is stopped depending on the intensity of the light received. A reflective storage stop phototube 48 is attached to the upper part of the back surface of the partition panel 1, and receives light to stop the storage of the partition panel 1.

Further, a phototube 49 for harvesting and flooring is attached to the upper part of the right end surface of the partition panel 1, and a motor 38 for harvesting and flooring is operated. A phototube 50 for starting storage is attached below the phototube 49 for grounding, and the partitioning panel 1
Now you can start storing. Note that a battery charging terminal 51 is provided at the lower right end surface of the partition panel l, so that the battery 3 can be charged one after another. In addition, an operation panel 52 is provided at the lower front of the partition panel l.
is provided so that the traveling motor 2 and the resection bed contact motor 38 can be operated.

FIG. 4 is a perspective view showing the drive rail 34 and the support rail 36 at a corner part, the support rail 36 forms a right angle part 36a, and the drive rail 34 is outside the right angle part 36a of the support rail 36. An arcuate portion 34c is formed that protrudes in an arcuate direction.

Now, the operation and effects of the self-propelled towing drive mechanism for the partition panel 1 configured as described above will be explained.

As shown in FIG. 1, when the partitioning phototube 46 first senses light from the wall side of the storage (not shown), the traveling motor 2 is driven to rotate. When the traveling motor 2 is rotated,
As shown in FIG.
, 10 to the case 9, and at the same time as the case 9 rotates, the bevel gears 11a, lie supported on the support shaft 12.
rotates, and by rotating the bevel gear 11b and lid that mesh with these, the rotating shafts 6a and 6b extending left and right rotate in the same direction, respectively.

When these rotating shafts 6a and 6b rotate, the bevel gears 17a' and 17b attached to the front end of the image mesh with the bevel gear 16 attached to the lower end of the vertical shaft 14, so that the vertical shaft 14 rotates. However, their rotation direction is the same as that of the rain vertical axis 14. The rotation of the rain vertical shaft 14 is transmitted to the drive roller 23 of the drive runner 18 via the coupling shaft 19. Since the drive roller 23 rotates while pressing the wall 34a of the drive rail 34, the partition panel 1 moves in a predetermined direction.

When this first partition panel 1 reaches the corner,
As shown in FIGS. 4 and 5, the drive runner 18 smoothly moves in an arc shape along the arc portion 34c of the drive rail 34. As shown in FIGS. On the other hand, the support runner 13 moves at right angles along the right angle portion 36a of the support rail 36.

At this time, as shown in FIG. 3, when the partition panel 1 approaches the corner, the drive runner 18 on the rear side in the direction of movement of the partition panel 1 comes to a nearly stopped state.
During this time, the front drive runner 18 changes its traveling direction and moves forward. q, the rotation of the vertical shaft 14 connected to the rear drive runner 18 almost stops, so that the bevel gear 16.
The rotating shaft 6b connected via the shaft 17b also almost stops.

Therefore, as shown in FIG. 2, the differential gear 7 works to stop the rotation of the bevel gear 11b, so that the bevel gear 11a and the bevel gear 11c, which mesh with the bevel gear 11b, mutually rotate around the support shaft 12. It starts rotating in the opposite direction. As a result, the rotational force of the case 9 is transmitted to the rotating shaft 6a via the bevel gears 11a, llc, and lid so as to rotate at approximately twice the speed.

Subsequently, when the partition panel 1 reaches the state shown by the two-dot chain line in FIG. 3, the front drive runner 18 almost stops, and during this time the rear drive runner 18 continues to move forward. At this time, contrary to the above, the front drive runner 18 almost stops, so that the rotation of the rotating shaft 6a almost stops.

Therefore, due to the action of the differential device 7, the rotating shaft 6b rotates at approximately twice the speed.

Further, although a force is applied to the upper connecting shaft 2o and the lower connecting shaft 21 in the direction of separating them from each other, the upper connecting shaft 2o and the drive roller 2
3 between the rotating shaft 24 and the lower connecting shaft 21 and the vertical shaft 14
Since there are universal joints 22 and 25 between them, the inclination angle of the connecting shaft 19 increases, the support pin 29 slides in the elongated hole 27, and the coil spring 32 is compressed. , the upper connecting shaft 2o and the lower connecting shaft 21 move gradually apart as they move around the corner.

In this way, the partition panel l is smoothly and quickly driven at the corner, and since the support rails 36 are formed at right angles, it is easy to install the support rails 36 on the ceiling. Support rail 36
There are fewer restrictions on the selection of installation locations. Moreover, the appearance when looking at the ceiling from below is good.

Next, when the partition panel 1 approaches the stile, the light from the travel stop phototube 47 is reflected on the stile, and the travel stop phototube 47 senses the light to stop the travel motor 2. At this time, since the drive runner 18 runs ahead of the partition panel 1, it stops at a position ahead of the stopping position of the partition panel l, and the partition panel 1 is moved by the coil spring 32 wound around the connecting shaft 19. Stop by pulling.

Next, the second partition panel 1 also moves out of the storage in the same way as the first partition panel l, approaches the first partition panel 1, and the travel stop phototube 47 is moved. It operates and comes into contact with the first partition panel 1 and stops. At this time, the first phototube 49 for enucleation is activated, the motor 38 for enucleation is rotated, and the vertical movement member 40 is deformed, so that the enucleation lifting shaft 41 rises and the enucleation is performed. The cushion 43 comes into contact with the ceiling, and the floor lifting shaft 44 descends to bring the floor cushion 45 into contact with the floor.

Therefore, the space between the upper edge of the partition panel 1 and the ceiling and the space between the lower edge of the partition panel 1 and the floor are completely shielded,
It exhibits functions such as airtightness and sound insulation. Subsequently, the partitioning panels 1 are sequentially pulled out from the storage in the same manner, and the partitioning is completed.

Next, storage of the partition panel 1 will be explained.

A phototube 50 for starting storage of light from a floodlight tube installed in a frame
When this is sensed, the harvesting bed landing motor 3B is driven to rotate, the picking lifting shaft 41 is lowered and the picking cushion 43 is separated from the ceiling, and at the same time the bed landing shaft 44 is raised and the bed touching cushion 45 is lifted up. Get off the floor. Subsequently, the traveling motor 2 is driven to rotate in the opposite direction to the above, and the differential device 7, the rotating shaft 6a,
6b, vertical shaft 4, drive roller 23 via connecting shaft 19
rotates in the opposite direction. Therefore, the drive runner 18 moves on the drive rail 34 toward the storage. Then, the partition panel 1 is stored toward the storage. Inside the storage, when the storage stop phototube 48 detects the light reflected on the storage internal wall or the partition panel 1,
The partition panel 1 stops moving. Similarly, the partition panels 1 are sequentially stored in the storage.

[Second Embodiment] Another embodiment in which the present invention is embodied in a rotating self-propelled drive mechanism for a partition panel will be described below with reference to FIGS. 9 to 15. In addition, in this embodiment, mainly the parts different from the above-mentioned first embodiment will be explained.

As shown in FIGS. 9 and 10, a drive runner 18 for moving the partition panel l is disposed above the vertical shaft 14 supported on the upper part of the partition panel l. A connecting shaft 19 is interposed between the rotary shaft 24 as a support shaft extending downward from the center of the lower part and the vertical shaft 14, and the connecting shaft 19 is connected by a universal joint 22, 25 whose both ends are rotatable in any direction. Rotational force is transmitted to the drive runner 18 via the connection shaft 19.

As shown in FIG. 1O, a drive roller 23 and a driven roller 60 are rotatably supported on both sides of the drive runner 18 (front side and back side in FIG. The rotational drive from the rotation shaft 24 is achieved by meshing the bevel gear 61 that constitutes the force transmission mechanism with the bevel gear 63 that is provided at the inner end of the support shaft 62 of the drive roller 23 and that also constitutes the drive force transmission mechanism. The force is transmitted to the drive roller 23, so that the drive roller 23 is rotationally driven. On the other hand, the driven roller 60 located at a position facing the driving roller 23 is not rotationally driven but can freely rotate, and as a result, the driving runner 18 can smoothly turn around the rotating shaft 24.

As shown in FIGS. 9 and 12, outer rollers 64 are rotatably supported at the four corners of the upper surface of the drive runner I8. Then, it can move along the straight portion 65a of the drive rail 34 and the outer circumferential wall 67 at the corner portion 66. Furthermore, between the two outer rollers 64 (above the drive roller 23), two inner rollers 68 are rotatably supported at a higher position than the outer roller 64, and the straight portion 65a of the drive rail 34 and It is movable along the inner circumferential wall 69 at the corner portion 66. Further, this inner roller 68 can move along an outer circumferential wall 70 shown by a two-dot chain line in FIG. 12, and as a result, the inner roller 68 is guided in a predetermined direction by the inner circumferential wall 69 and the outer circumferential wall 70. Therefore, in this case, the outer peripheral wall 6
7 can be omitted.

Now, the operation and effect of the rotating self-propelled drive mechanism of the partition panel 1 configured as described above will be explained.

As in the first embodiment, the rotational force of the rotating shafts 6a, 6b is transmitted to the vertical shaft 14 via the differential gear 7 by the operation of the traveling motor 2. The rotation of the vertical shaft 14 is connected to the connecting shaft 19.
The rotation of the rotation shaft 24 is transmitted to the drive roller 23 via the umbrella gears 61, 6.3. Since the drive roller 23 rolls on the drive rail 34, the partition panel l moves in a predetermined direction.

When this first partition panel 1 reaches the corner portion 66 of the drive rail 34, as shown in FIG.
The movement of the drive runner 18 almost stops, and at this time the other drive runner 18 moves at a faster speed due to the action of the differential device 7.

Therefore, the partition panel 1 can be moved smoothly and quickly in the corner portion 66.

Note that at the corner portion 66, the drive runner 18 turns in the following manner.

As shown in FIG. 12, the outer roller 64 of the drive runner 18 enters the turning area 71 of the drive rail 34, and one of the inner rollers 68 reaches the inner peripheral wall 69 at the corner portion 66.

Next, as shown in FIG. 13, when the drive runner 18 moves further and the drive roller 23 rotates at that position, the inner roller 68 moves along the inner circumferential wall 69 and the outer circumferential wall 70. At this time, the corner of the inner peripheral wall 69 is a rotation permissible corner 72 formed in an R shape to allow the rotational movement of the inner roller 68, so the inner roller 68 is rotated at the rotation permissible corner of the inner peripheral wall 69. 72 smoothly.

Next, as shown in FIG.
When rotated by 0 degrees, the inner circumferential wall 6 on which the inner roller 68 is located
9 is a right-angled rotation stop corner 73 for stopping the rotation of the inner roller 68, so the inner roller 68 cannot rotate any further, and therefore the drive runner 18 starts moving forward (to the left in Figure 14) from that position.

Subsequently, as shown in FIG. 15, the drive runner 18 moves to another straight part 65b extending from the turning area 71 in a direction perpendicular to the straight part 65a of the drive rail 34. In this way, the drive runner 18 changes its direction of movement at right angles and moves smoothly.

Note that the connecting shaft 19 provided between the drive runner 18 and the partition panel l is connected at both upper and lower ends with universal joints 22.25, so that the partition panel 1 is pulled by the drive runner 18. Since the drive rail 34 is formed at right angles, it is easy to install the drive rail 34 on the ceiling, and the selection of the installation location for installing the drive rail 34 is easy. There are few restrictions on Moreover, the appearance when looking at the ceiling from below is good.

The present invention is not limited to the above-described embodiments, and may be configured as follows without departing from the spirit of the invention.

(1) In the first embodiment, the support rails 36 at the corner portions are formed at right angles, but they may be formed in a somewhat rounded shape. In this case as well, support runner 1
3 can move smoothly around corners.

(2) Partitioning phototube 46, traveling stop phototube 47, storage stop phototube 48 in the first and second embodiments,
The installation position of the phototube 49 for cutting and flooring and the phototube 50 for starting storage may be on the front surface, back surface, both end surfaces, etc. of the partition panel l, depending on the installation location, shape, purpose of use, etc. of the partition panel l. There is no problem even if it is.

(3) In addition to the partition panel 1 of the first and second embodiments, examples of the moving body in the present invention include a crane for moving articles used in a factory. In this case as well, the drive runner 18 can turn smoothly not only in straight sections but also in corner sections 66.

(4) In the second embodiment, the shape of the corner of the inner circumferential wall 69 in the turning area 71 of the drive rail 34 is such that the drive runner 18 rotates 270 degrees in the above embodiment, but it may be changed depending on the purpose. It can also be rotated by 90 degrees or the like.

(5) In the second embodiment, by correspondingly changing the height of the inner roller 68 and the height of the inner circumferential wall 69, the drive runner 18 can be moved from running in a straight line to branching rails.

〔Effect of the invention〕

According to the drive mechanism for a movable body according to the first aspect of the present invention, since the driving force of each of the pair of drive runners is appropriately controlled by the differential device, traveling particularly around corners is performed smoothly and quickly. , it is possible to arrange the rails at the corners almost at right angles, and as a result, the construction of the rails is easy and there are fewer restrictions on where they can be installed.
Moreover, the effect is that the appearance is well maintained.

Further, according to the drive mechanism of the movable body of the second invention, the support runner moves along the support rail at the same time as the drive runner moves along the drive rail, and the connecting shaft is formed to be rotatable. Therefore, the effect of the first invention can be more reliably achieved.

Furthermore, according to the drive mechanism for a moving body of the third invention, the drive roller rolls on the drive rail via the drive force transmission mechanism based on the drive force of the support shaft of the drive runner, and the driven roller Since the drive roller rolls according to the movement of the drive roller, as a result, the drive runner can smoothly and reliably turn in a predetermined direction at the corner portion, and the effects of the first aspect of the invention can also be achieved.
