Description

Detailed Description of the Invention (Field of Industrial Application) The present invention relates to a partitioning device used mainly for partitioning a hall in a building, particularly a partitioning device using a large partitioning panel. The present invention relates to a device for rotationally driving a utility panel in order to switch between an active position for forming a partition wall and an open position for forming a passage for people.

(Prior art and its problems) A partitioning device that uses large partitioning panels, such as dividing a wall into appropriate dimensions, as a partitioning device that has a high function as a wall (sound insulation effect, strength, etc.) when in use. It has been known.

In a conventional partitioning device of this kind, unless all of the plurality of partitioning panels movable along the partitioning path are stored in the panel storage section formed at the end of the partitioning path, the partitioning device cannot move. It is not possible to allow people to come and go across the entire width of a hall partitioned by a cross. In other words, when switching between a state in which a hall is partitioned with a partition device and an open state without partitions, it is necessary to move all of the large and heavy partition panels, so it takes a lot of effort to switch between the partitioned state and the open state. This requires time and effort, and it is difficult to quickly switch to the open state even in an emergency.

As a partition device that can solve such problems, when a partition panel that is movable along a partition path is in a working position forming one continuous partition wall, the working position parallel to the partition path and the path A partitioning device has been devised in which the panel can be rotated between an open position orthogonal to the open position.

In a partition device using such rotatable partition panels, a passage for people can be formed between each panel by rotating each panel on the spot without having to move each panel along the partition path. However, if the partition panels, which are large and heavy, are rotated by input, it requires a lot of effort and time to switch all the panels to the open position, so a drive to rotate each panel is required. equipment is required. However, if a rotary drive device is mounted on a movable platform that rotatably hangs each panel, not only will the labor required to move the panels along the partition path increase;
Compared to a case where the rotary drive device is fixed, the power supply means etc. are more complicated and the cost is higher. on the other hand,
Since it is dangerous if each panel unexpectedly rotates when moving it along the partition path, this point must also be solved.

(Means for Solving the Problems) The present invention proposes a rotational drive device for a partition panel that can solve the above problems, and is characterized by a partition panel that can be moved along a partition path. A locking means for rotatably suspending a partition panel from each of the plurality of movable bases via vertical support shafts for driving panel rotation, and locking the panel relative to the movable base in a partitioning posture parallel to the partition path. is provided, and when each panel is in the partition operating position where each panel continuously forms one partition wall, an elevating rotating shaft is provided that is located directly above the vertical support shaft, and the elevating and lowering driving means and rotation of the elevating rotating shaft are provided. and a driving means is provided, and an engaging portion is provided on the vertical support shaft and the vertical support shaft to engage with each other in a rotation transmission state when the vertical rotation shaft is lowered by a predetermined amount, and further, when the vertical rotation shaft is lowered by a predetermined amount. An elevating member that is pushed down against a spring is provided in the panel, and the elevating member and the locking means are interlocked and connected so that the locking state of the locking means is released by the lowering of the elevating member.

(Function of the Invention) According to the partitioning panel rotation drive device of the present invention, when the elevating rotation shaft is lowered by a predetermined amount by the elevating drive means with each panel in the partitioning operation position, the elevating rotation is lowered by a predetermined amount. The shaft and the vertical support shaft for driving the panel rotation are engaged in a rotation transmission state through respective engaging portions. At the same time, the lifting and lowering rotation shaft is lowered by a predetermined amount, so that the panel is unlocked by the locking means, and the panel becomes rotatable about the vertical support shaft relative to the movable table. Therefore, by rotating the elevating rotation shaft by, for example, 90 degrees by the rotation drive means, the rotation is transmitted to the panel via the engaging portion and the vertical support shaft,
The panel can be rotated from a partitioning position parallel to the partitioning path to an open position perpendicular to the partitioning path.

When returning the panel from the open position to the original partitioning position, it is sufficient to reverse the vertical axis of rotation to its original state, and then lift it up and remove it from the vertical axis of rotation. As a result, the panel returns to its original partitioning position, and at the same time is locked to the movable base in this position by the locking means.

(Effects of the Invention) According to the device of the present invention, each partition panel can be rotated on the spot around the vertical support axis and switched to the open position without moving it along the partition path, and the adjacent However, since the device for rotationally driving the panel, that is, the lifting rotation shaft, the lifting driving means, and the rotational driving means are installed beside the partition path. Compared to the case where this panel rotation drive device is mounted on a movable base for suspending the panel, the load when moving the panel along the partition path is reduced, and the work of moving the panel can be performed easily and easily. Furthermore, power can be reliably supplied to the rotary drive device using simple means, and can be implemented at low cost.

Furthermore, when moving the panel along the partitioning path, the panel can be fixed to the movable base in a partitioning posture parallel to the partitioning path by the locking means, so that the work of moving the panel can be carried out safely and smoothly. I can do it. Furthermore, when rotating the panel, the panel can be automatically unlocked by the downward movement of the lifting and lowering rotation axis in the panel rotation drive device, so the locking means can be unlocked by a separate operation before rotating the panel. This eliminates the need to release the lock with the lock, and also eliminates the need to provide a separate means exclusively for releasing the lock, making the structure simple and inexpensive to implement.

As shown in the figure and FIG. 4, it is composed of an elevating rotation shaft 24, an elevating and lowering drive means 25 for this elevating and lowering rotating shaft 24, and a rotation driving means 26 for the elevating and lowering rotating shaft 24,
As shown in FIG. 5, the elevating rotation shaft 24 is connected to the cylindrical vertical support shaft 10 via an upper wall through hole 27 of the guide rail 3 and an upper wall through hole 28 of the movable table 5.
It is provided with a rotary operation piece 30 that fits into the engagement groove 29 formed in the upper peripheral wall of the vertical support shaft 10 when the vertical support shaft 10 enters and descends to a predetermined depth. 15 is pushed down by a predetermined amount against the spring 16.

The elevating drive means 25 of the elevating rotation shaft 24 includes an elevating rack gear 31 and a motor 33 that drives the elevating rack gear 31 upward and downward via a pinion gear 32, and includes a pair of upper and lower supports connected from both upper and lower ends of the elevating rack gear 31. Arms 34a, 34b

is fitted to the vertically rotating shaft portion 24a between the two bearings 35a and 35b via a keyway 36a and a key 36b so that only relative vertical movement is possible, and is supported by the fixed frame 37 via a bearing 38 so that only rotation is possible. a rotary disk 39, a chain 40 fixedly stretched around the rotary disk 39 (not shown in FIG. 4), a tooth ring 41 that meshes with the chain 40, and a tooth ring 4.
The motor 43 rotates the motor 1 in any forward or reverse direction via a speed reducer 42.

The roller units 4 for suspending the movable bases 5 and 6 are rotatable on respective vertical shafts 44 that project upward from the movable bases 5 and 6, as shown in FIGS. 3 and 6. The guide rail 3 includes two supported upper and lower rollers 45a and 45b, and the guide rail 3 includes an upper inclined rail part 46a that supports one side of the upper roller 45a, and a lower inclined rail part 46a that supports the opposite side of the lower roller 45b. rail part 46b,
and a guide groove portion 46c in which the vertical shaft 44 moves.

In the panel storage position 8 shown in FIGS. 1 and 2, there are a pair of lateral movement guide rails 47a and 47b that guide a pair of front and rear roller units 4 for suspending each panel 1, 2, as shown in FIG. It is being constructed. These lateral movement guide rails 47a, 4
7b is the same as the guide rail 3, and is installed so that the guide groove 46c communicates with the guide rail 3 at right angles to the guide rail 3 extending to the panel storage position 8. Further, as shown in FIG. 2, this panel storage position 8 is covered by a fixed wall 48 and a movable wall 49 that can be opened and closed when taking the panels 1 and 2 in and out.

The auxiliary panel 2 shown in FIGS. 1 and 2 is
It is suspended on a movable base 6 in a partitioning posture, and cannot rotate relative to this movable base 6 like the other main panels 1. When the panel is finally pulled out from the panel storage position 8 to the partition path, it is used with the rear side remaining in the panel storage position 8, and at this time, the part protruding from the panel storage position 8 has an emergency A door 50 is provided. Of course, this auxiliary panel 2 is not essential to the present invention, and the main panel 1 can be used for all panels. In addition, in the examples shown in FIGS. 1 and 2, the panel storage positions 8 are provided at both ends of the partition path because the guide rail 3 is separated by the presence of the beam 7, but the panel storage positions 8 are provided at both ends of the partition path. If the guide rail 3 can be constructed continuously, the panel storage position 8 can be provided only at one end.

In FIGS. 4 to 6, 52 is a cover that covers the guide rail 3 and the moving path of the movable platforms 5 and 6, and 53 is a ceiling plate.

Next, to explain how to use it, when forming a partition with each panel 1 and 2 as shown in FIGS. Then pull it out to the partition path. At this time, the lateral movement guide rail 4
Panels 1 and 2 hanging from 7a and 47b
The roller unit 4 is moved laterally along the lateral movement guide rails 47a and 47b until it reaches a position directly below the guide rail 3, and once the roller unit 4 enters the guide rail 3, the panels 1 and 2 are moved along the guide rail 3.
Just pull it out at right angles. In addition, auxiliary panel 2
is finally pulled out from the panel storage position 8 as described above.

The panels 1 and 2 pulled out from the panel storage position 8 are in the partitioning posture a parallel to the guide rail 3, and in particular, the main panel 1, which is rotatable with respect to the movable base 5, is locked by the locking means 23 into the partitioning position a. It is locked in working position a. However, when each panel 1, 2 is pulled out to a predetermined partition working position A as shown in the figure, each panel 1, 2 continuously forms one partition wall, but at this time, the center of rotation of each main panel 1 The vertical support shaft 10 located is
It is located directly below the lifting and lowering rotation shaft 24 in the corresponding panel rotation drive device 9. In this way, each panel 1, 2 forms a partition wall, but it is desirable to also use locking means to prevent each panel 1, 2 from moving unexpectedly from the partitioning position A. As this locking means, for example, the first
As shown in the figure, each panel 1 has a lock pin 51 that can be inserted into and removed from a locking hole provided on the floor side.
However, regarding the main panel 1, there is no need to pull out the lock pin 51 each time the main panel 1 is rotated around the vertical support shaft 10, and the main panel In order to ensure safe and smooth rotation, it is desirable that the lock pin 51 be provided concentrically with the vertical support shaft 10, and that the lock pin 51 be configured to be rotatable relative to the locking hole on the floor side.

When opening the partition wall formed by each panel 1 and 2 as described above to allow people to come and go freely, the elevating and lowering drive means 2 of each panel rotation drive device 9
5, the lifting and lowering rotation shaft 24 is lowered to a predetermined position. That is, the motor 33 causes the pinion gear 32 to
When the elevating rotary shaft 24 is lowered to a predetermined position relative to the rotary disk 39 by rotating the rack gear 31 and lowering the rack gear 31, the elevating rotary shaft 24 penetrates the upper wall of the guide rail 3 as shown in FIG. Hole 2
7 and the upper wall through hole 28 of the movable base 5 to enter and descend into the cylindrical vertical support shaft 10 to a predetermined depth, and the rotation operation piece 30 is fitted into the upper end engagement groove 29 of the vertical support shaft 10. At the same time, the vertical support shaft 10
Push down the inner lifting rod 15 by a predetermined amount against the spring 16. As a result, as shown in FIG. 6, both lock pins 12a and 12b, which had been fitted into the pin holes 21 of the locking fitting 20 on the movable base 5 side, are pulled down by the lifting frame 14 and separated from the pin holes 21. Since the main panels 1 are unlocked by pressing the main panel 1, each main panel 1 becomes rotatable about the vertical support shaft 10 with respect to the movable table 5.

Next, the rotation drive means 26 in the panel rotation drive device 9 is operated to rotate the elevating rotation shaft 24. That is, when the gear wheel 41 is rotated by the motor 43 and the rotary disk 39 is rotated 90 degrees forward through the chain 40, the rotation causes the key 36b and the keyway 36a to rotate.
The power is transmitted to the vertical shaft 24 through the rotating operation piece 30 and the engagement groove 29, so that each main panel 1 rotates 90 degrees around the vertical shaft 10. , as shown by the imaginary line in FIG. 2, it is switched to the open position b that is perpendicular to the partition path. Therefore, wide passages are formed between adjacent panels 1 and between panels 1 and 2. At this time, by opening the emergency door 50 of the auxiliary panel 2 as shown by the imaginary line in FIG. 2, the passage between the panels 1 and 2 can be sufficiently widened.

In order to return each main panel 1 which has been switched to the open position b to the partition working position a, the rotation driving means 26 may be operated in the reverse direction to reversely rotate the elevating rotary shaft 24 by 90 degrees while remaining in the lowered position. When the main panel 1 is thus returned from the open position b to the partition working position a, the elevating drive means 25 is operated in reverse to raise the elevating rotation shaft 24 to its original position, thereby moving the movable base 5 to the elevating rotation shaft 24. At the same time, the lifting rod 15, which had been pushed down by the lifting rotation shaft 24, returns to the upper position due to the biasing force of the spring 16, and the lifting frame 1
Both the lock pins 12a and 12b rise through the pin hole 2 in the locking fitting 20 of the movable base 5 again.
1, and the main panel 1 is locked to the movable base 5 in the partitioning posture a.

When storing each panel 1, 2 in the panel storage position 8, it is sufficient to move each panel 1, 2 in the opposite manner to when pulling it out from the panel storage position 8. Lifting rotation axis 2
When the main panel 1 is moved along the guide rail 3, when the main panel 1 is moved along the guide rail 3, the main panel 1 is moved along the guide rail 3. The main panel 1 is always locked in the partition working position a parallel to the guide rail 3, and the main panel 1 can be stored and pulled out safely and easily.

In addition, on the side of each panel 1, 2, each panel 1,
An elastic packing material can be attached to close the gap between adjacent panels when the panels 2 form a partition wall. In addition, it is possible to install elastic packing material on both sides of the top and bottom of each panel 1 and 2 to close the gaps with the ceiling and the floor, but this packing material will prevent the movement of panels 1 and 2. It must not be an obstacle to rotation, so
It must be constructed so that it can be raised and lowered.

FIG. 8 shows an example of a case where a packing material 54 that can be raised and lowered is attached to the upper sides of the panels 1 and 2. The packing material 54 is attached to the upper surface of an elevating frame 55 which is fitted into the upper sides of the panels 1 and 2 so as to be able to rise and lower. When the elevating frame 55 is pushed up by a spring 56, Packing material 54 is provided on the lower surface of the cover 52 located on both left and right sides of the passage through which the vertical support shaft 10, lock pins 12a, 12b, etc. pass.
It is configured so that they come into pressure contact. This elevating frame 55 can be pulled down against the spring 56 and locked in the lowered position by appropriate operating means provided on the panels 1, 2.
