DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a panel traveling apparatus having a drive runner connected to a panel and running along a rail.

[0002]

2. Description of the Related Art Conventionally, there is a technique in which a partition panel is suspended from a ceiling rail by a pair of front and rear drive runners, and the drive runner is driven to move the partition panel. For example, as shown in FIG. 9, the partition panel 90 is generally taken out of the storage box by each of the drive runners 91 self-propelled along the rails 94, and in the corner portion C, the drive runners 91 change direction and partition. It is going to advance in the direction.

However, once the power supply to the drive runner 91 is cut off due to a power failure, controller malfunction, or the like, the drive runner 91 cannot run on its own. In this case, for example, the user pushes and moves the partition panel 90. At this time, if the rail 94 is a straight line, pressing the partition panel 90 causes the driving runner 91 to also move the rail 94.
Move together along. However, when the drive runner 91 reaches the corner portion C, the drive runner 91 does not change direction no matter how the partition panel 90 is pushed. That is, the panel 90 cannot be moved unless the traveling direction of the drive runner 91 is directed to the exit side of the corner portion C.

To turn the drive runner 91 at the corner C, a handle is inserted from outside the panel 90 into a gear box (not shown) provided in the panel 90, and the handle is rotated. As a result, the drive mechanism that connects the gear box and the drive runner 91 is manually driven, and the drive runner 91 turns horizontally to face the exit side of the corner C. As a result, the partition panel 90 can be moved.

[0005]

However, the turning of the drive runner 91 must be performed manually by operating the steering wheel. That is, the insertion holes for inserting the handles are provided on the front and rear of the panel 90. When the drive runner 91 is manually turned, the handle is alternately inserted into the front and rear insertion holes for operation. Will be done. As described above, the operation of escaping the panel 90 from the corner portion C at the time of a power failure or the like is very troublesome.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object of the present invention is to provide a panel traveling device capable of performing a turning operation of both drive runners by one operation. .

[0007]

In order to achieve the above object, according to the first aspect of the present invention, a pair of first and second self-propelled members are connected to an upper portion of a panel and run along a traveling path having a straight portion and a corner portion. The first drive runner and the second drive runner are respectively connected to the respective drive runners. When the drive runners reach the corners of the travel path, the drive runners are rotated in the horizontal direction to change the traveling direction of the panel. First and second direction changing means for changing, and the first direction changing means;
First and second direction change means when each of the drive runners passes through a straight portion and a corner portion of the travel path. And a differential gear device that adjusts the rotational speed difference between the gears by a driving force from the outside of the panel .

[0008] In the invention according to claim 2, the gist is that the rotation of the first and second direction changing means is performed by a manual handle operation from outside the panel via the differential gear device.

[0009]

Therefore, according to the above configuration, during a power failure, a person pushes or pulls the panel to move it. When the drive runner reaches the inside of the corner portion, by rotating the handle from the outside of the panel, its power is transmitted to the first and second direction changing means via the differential gear device. Accordingly, the first and second drive runners rotate in a predetermined direction, and the traveling direction of the panel is changed.

At this time, one drive runner (for example,
When the first drive runner is disposed at the corner of the traveling path and the other driving runner (second driving runner) is disposed at the straight traveling section of the traveling path, only the first driving runner turns. The second drive runner is not turned since the turning operation is restricted by the traveling route.
That is, in this case, the difference between the rotation speeds of the first and second direction changing means is adjusted by the action of the differential gear, so that even if the steering wheel is rotated, the power is kept at the second level.
Is not transmitted to the drive runner.

As shown in FIG. 1, the driving runner R1,
R <b> 2 is arranged in the rail 40 configuring the travel route K. The drive runners R1 and R2 have an outer shell formed by a substantially rectangular parallelepiped metal main body 41, and running rollers 42 are provided on both sides (only one is shown) of the main body 41. The traveling roller 42 rotates positively by the driving force of a motor (not shown) that can rotate forward and reverse, and travels in the rail 40. The motor is one for each running roller 42.
Each is provided. The turning of the drive runners R1 and R2 during normal running is performed by the controller 50 disposed in the panel 1 changing the rotation direction of the left and right running rollers 42.

A pair of front and rear side gears 49 mesh with the pinion 47. The first power transmission shaft 31 and the second power transmission shaft 35 are keyed to the side gear 49, respectively.

Next, the operation of this embodiment will be described.
First, the operation of the partition panel 1 during normal traveling (during power supply) will be described. When the traveling rollers 42 of the respective drive runners R1 and R2 are positively rotated, the panel 1 travels along the traveling path K accordingly. And, for example,
When the first drive runner R1 reaches the corner C while the first drive runner R1 is traveling ahead of the panel 1, the controller 50 causes the left and right traveling of the first drive runner R1. The rotation direction of the roller 26 is reversed. Therefore, the turning of the first drive runner R1 at this time is performed around the turning shaft 33.

The turning operation ends when the first drive runner R1 faces the exit of the corner C. At this time, with the turning of the first drive runner R1, the first power transmission shaft 31 is transmitted via the bevel gear 34 and the bevel gear 32.
Although but is rotated, the second driving runner R2 is impossible pivot positioned straight portion S, the second power transmission shaft 35
Does not rotate. Therefore, the differential gear device D
Performs a differential operation by rotation of only the pinion 47.

[0025] Then, first the rotational speed of the left and right track roller 42 of the drive runner R1 becomes the same single rotation number again, the first driving runner R1 travels a straight portion S of the travel route K. At this time, both drive runners R1 and R2 are
The drive runners R1 and R2 rotate relatively to the partition panel 1 because the direction of the partition panel 1 gradually changes until the vehicle passes through the partition panel 1. This turning is permitted by the differential operation of the differential gear device D.

When the second drive runner R2 reaches the corner portion C, the second drive runner R2 is also moved around the turning shaft 37 in the same manner as the first drive runner R1 under the control of the controller 50. Turned. As described above, during normal traveling, the controller 50 controls the rotation of the traveling rollers 42 of the driving runners R1, R2, and the turning operation of the driving runners R1, R2 is performed.

Next, an operation when the panel 1 is moved when the power supply to each of the drive runners R1 and R2 is stopped due to a power failure or the like will be described. When the power supply to the drive runners R1 and R2 is stopped and the panel 1 cannot run on its own, the user presses (or pulls) the panel 1 to move the panel 1. At this time, when the drive runners R1 and R2 are disposed in the straight traveling portion S of the traveling route K, the panel 1 moves along the traveling route K simply by pressing the panel 1. Then, as shown in FIG. 5, the drive runner R1 is
Is reached, the user inserts the handle 21 into the handle insertion hole 20a of the gearbox 20 and performs a rotating operation in a predetermined direction. At this time, the turning force of the handle 16 is
The power is transmitted to the differential gear device D via the gear box 20, the connection shaft 23, and the drive shaft 27.

Here, the power transmission process in the differential device 26 will be described. The torque transmitted to the drive shaft 27 is transmitted through the drive gear 43 to the ring gear 4.
5, that is, transmitted to the differential case 44. Then, as the differential case 44 rotates, the pinion 47 rotates (revolves). Then, the rotational force is transmitted to the side gear 49, that is, the first and second power transmission shafts 31, 35.

At this time, since the first driving runner R1 is disposed at the corner C, the turning thereof is free. However, since the second drive runner R2 is disposed in the straight traveling portion S of the traveling route K, the turning operation is restricted. Therefore, in this case, the pinion 47 rotates at the same time as the revolution. That is, the pinion 47 rotates and adjusts the difference between the rotational speeds of the two drive runners R1 and R2 simultaneously with the revolution. Therefore, in this case, only the first power transmission shaft 31 is rotated. That is, as the handle 21 rotates, only the first drive runner R1 performs the turning operation.

Then, as shown in FIG. 6, after turning the first drive runner R1 until it faces the exit of the corner portion C, the rotation of the handle 21 is stopped, and the panel 1 is moved by pushing the panel 1 again. can do. Then, as shown in FIG. 7, when the second drive runner R2 reaches the corner portion C, as shown in FIG. 8, the steering wheel 21 is rotated in the same manner as in the turning operation of the first drive runner R1. The second drive runner R2 is turned.

As described above, according to this embodiment, the space between the first and second turning shafts 33 and 37 connected to the first driving runner R1 and the second driving runner R2 is established. They were connected by a differential gear device D. When the power supply to the drive runners R1 and R2 is stopped, the differential gear device D is manually rotated by operating the handle 21.
As a result, the two drive runners R1 and R2 can be turned by operating the handle 21 at one place, so that the partition panel 1 can be moved quickly even during a power failure or the like.

The present invention is not limited to the above-described embodiment, but may be configured as follows without departing from the spirit of the invention. (1) In the above embodiment, the turning of the drive runners R1, R2 was performed by making the rotation directions of the left and right running rollers 42 different, but this was achieved by driving the differential gear device D by a motor to drive the runners R1, R2. May be turned.

(2) In the above embodiment, the handle 21 is detachable from the handle insertion hole 20a of the gear box 20, but the handle 21 is fixedly provided in the handle insertion hole 20a of the gear box 20. It may be embodied. In this case, even at the time of a power failure or the like, the drive runners R1 and R2 can quickly turn, and the handle 21 can be prevented from being lost.

[0034]

As described in detail above, according to the present invention,
Since the turning operation of the two drive runners can be performed by one operation, there is an excellent effect that the panel can be quickly moved even during a power failure or the like.
