Description

DETAILED DESCRIPTION OF THE INVENTION "Field of Industrial Application" The present invention relates to an automatic opening/closing method for automatically opening and closing an accordion curtain and preventing the curtain from rolling during opening and closing.

"Prior Art and its Problems" Conventionally, this type of accordion curtain has been hung from the ceiling. Therefore, when opening and closing the accordion curtain, the ceiling side (upper end)
Although the opening and closing movement of the curtain operates smoothly, the free end side (the open side of the pair of left and right accordion curtains) and the floor side (lower end part) may move blindly or sway horizontally, making it difficult to ensure smooth opening and closing movement. is the current situation.

In addition, when there is wind etc., the free end side and the lower end part
There were problems such as instability caused by the wind and the need to take some measures to prevent this.

As for the technical literature related to these,
There is an invention of a gymnasium partition device in Japanese Patent Publication No. 61-9467, the gist of which is that the net and the shielding member are suspended from the ceiling, and the winding motor and the winding cord arranged on the ceiling are connected to the partitioning device. It has a structure in which the net and the shielding member are raised and lowered. Mata Tokuko Showa 61-
No. 22713 discloses an electric opening/closing device for an accordion door, the gist of which is that the accordion door is opened and closed by raising and lowering a nut member screwed onto a threaded rod. In addition, special public service 1978-
No. 30998 discloses a flat horizontally opening type shutter, the gist of which is that wire is wound around both ends of the shutter through the rotation of a wire winding wheel mounted on a horizontally suspended wire winding shaft. This structure allows the shutter to be opened and closed by taking and rewinding the film.

The above technical documents are difficult to apply to the method of opening and closing the accordion curtain that is the object of the present invention, and it is considered impossible to open and close the accordion curtain as smoothly as before. Shōtokuko Showa 58−
No. 30998 has a structure that opens and closes by winding and unwinding the wire placed at both ends of the shutter through the rotation of a wire winding wheel, and also prevents the adverse effects caused by the large and small diameter of the wire winding wheel. Therefore, improvements have been made to uniform speed winding and unwinding.
However, this is not enough; furthermore, the pair of wire winding wheels do not necessarily wind and unwind with equal diameters, and uneven tension is applied to the wire, making it difficult to open and close the shutter smoothly. There were some unimaginable problems. In addition, from the above points, even in the case of a panda graph accordion curtain, if the above-mentioned configuration is used, uneven tension will be applied, and smooth winding and unwinding cannot be expected. Possible drawbacks include the inability to open and close the accordion curtain in a hanging state.

``Means for Solving the Problems'' In view of the above, the present invention provides an automatic opening/closing method that allows pandagraph accordion curtains to open and close smoothly in a drooping state without swaying. is a pair of left and right accordion curtains that are foldably hung in a room, etc., and the pair of accordion curtains is driven by a rotating driving means such as an endless chain or an endless belt disposed above the accordion curtains. When opening and closing with a door roller that moves back and forth, at the same time, a pair of interlocking loops such as an endless belt or endless rope attached to the free end side and lower end of a pair of accordion curtains are arranged in parallel in the direction of the partition. The free end side is opened and closed through a means, so that the pair of accordion curtains can be folded in a hanging state at all times, and the driving circulating means and the interlocking circulating means are connected to each other, and the driving circulating means and the accordion curtain are connected to each other. By simultaneously operating the left and right trolleys linked to each other, the free end side of the accordion curtain is always maintained and controlled in a hanging state when the accordion curtain is opened or closed.

"Operation" Next, to explain the operation of the present invention, first, when trying to fully open a closed accordion curtain (in principle, partially opening is almost the same),
When the drive device (engine) for the accordion curtain is turned on, the drive circuit moves to one side, for example, in the clockwise direction in FIG. The accordion curtain slides (forwards) toward the fixed end side (the wall side of the partition), and through this sliding transition, the panda graphs (not shown) of the left and right accordion curtains respectively At the same time as the accordion curtain is folded one after another, from its free end to its fixed end, the accordion curtain is also folded in a similar manner. And in the folding process,
As the trolley slides from the center of the partition to its side edge (wall side), the interlocking mechanism is stretched between the guide pulleys attached to the outer part of the accordion curtain via the trolley. Specifically, when the opening/closing endless belts are rotated (transferred in the forward direction), the lower end of the free end of the accordion curtain is folded in accordance with the folding of the panda graph, and at a constant speed. While moving toward the side end portion, the accordion curtain is maintained in a drooping state,
Since the accordion curtain is opened reliably, the accordion curtain is maintained in the fully open state by stopping the operation of the drive device (in the case of partial opening, the operation is stopped midway).

Conversely, when attempting to close an open accordion curtain (in principle, partially blocking it is similar), when the accordion curtain drive device (engine) is turned on, either one of the drive circulating means, for example As the circuit moves counterclockwise in Fig. 1, the carts on the wall side of the partition each slide toward the center of the partition (move backward). Then, through this sliding transition, the panda graphs of the left and right accordion curtains are sequentially stretched, and at the same time, the accordion curtains are stretched sequentially from their free ends. Eventually, all of the pandagraph and accordion curtain will be extended at the same time (although there may be times when they are stopped after being partially extended). and,
During this stretching process, as the trolley slides from the side edge to the center of the partition, the tension is stretched between the guide pulleys attached to the outer part of the accordion curtain via the trolley. Specifically, when the endless opening/closing belts are rotated (reversely rotated), the lower end of the free end of the accordion curtain moves in accordance with the expansion of the panda graph. As the accordion curtain moves to the central part at a constant speed, the accordion curtain is maintained in a drooping state and is reliably closed.
At this point, the accordion curtain is maintained in the closed state by stopping the operation of the driving device (in the case of partial blockage, the operation is stopped midway).

``Embodiment'' An embodiment of the present invention will be described in detail below based on the drawings. Reference numeral 1 represents a wall portion of a partitioning area such as a room, and 2 represents a ceiling portion thereof. Reference numeral 3 denotes a driving circulating means such as an endless chain or an endless belt provided near the two ceiling surfaces of the partition, and left and right carts 4 are installed at corresponding positions on the upper surface 3a and lower surface side 3b of this driving circulating means 3, respectively. , 5 are fixed respectively. One of these carts 4 (the cart 4 located on the right side in the drawing when the accordion curtain is opened, which will be described later) is fixed with an upper end 6'a on the free end side of one of the accordion curtains 6a constituting the accordion curtain 6. At the same time, the upper end 6'b of the free end side of one of the accordion curtains 6b constituting the accordion curtain 6 is fixed to the other cart 5 (the cart 5 located on the left side in the drawing when the accordion curtain is opened, which will be described later). Stop.

In the figure, reference numerals 8 and 9 indicate door wheels for hanging the one accordion curtain 6a and the other accordion curtain 6b, which slide on a guide rail (not shown). Reference numeral 10 denotes a driving device such as an engine or a motor for driving the driving circulating means 3, and 11 and 12 are guide pulleys for tensioning the driving circulating means 3.

In the figure, reference numeral 14 denotes a plurality of guide pulleys provided on the outer part of the accordion curtain 6. This guide pulley 14 is wrapped with an interlocking circulating means 15 such as an endless belt or an endless rope. Both ends of the upper side of the means 15 are fixed to the other truck 5, and at the lower center and slightly to the left (however, when the accordion curtain 6 is closed), the other accordion curtain 6b is fixed. The lower end 6''b of the free end side is fixed. Reference numeral 16 denotes a plurality of guide pulleys provided on the outer part of the accordion curtain 6.
The other interlocking circumferential means 17 such as an endless belt or an endless rope is wrapped around the interlocking circumferential means 17, and both upper ends of the interlocking circumferential means 17 are fixed to one of the carts 4, and the lower side At the center and slightly to the right (when the accordion curtain 6 is closed), there is a lower end 6''a on the free end side of the one accordion curtain 6a.
is fixed. In the above example, a configuration in which the guide pulleys 14 and 16 are provided separately has been described, but it is of course possible to use both guide pulleys 14 and 16 in common.

Next, to explain the operation of the present invention in detail, first, when trying to fully open the closed accordion curtain 6 (in principle, partially opening is almost the same), turn on the accordion curtain drive device 10. When one of the drive circulating means 3 rotates, for example, clockwise in FIG. sliding towards
Specifically, in the drawing, the cart 4 slides to the right and the cart 5 slides to the left, and through this sliding movement, the panda graphs (not shown) on one accordion curtain 6a sequentially move. At the same time as the accordion curtain 6a is folded from the free end side toward the wall portion 1 side, one accordion curtain 6a is also folded in a similar manner. Also, the panda graphs (not shown) of the other accordion curtain 6b are sequentially folded, and at the same time, the panda graphs (not shown) of the other accordion curtain 6b are folded from their free ends toward the wall 1 side. are also folded in a similar manner one after another.

In this folding process, the carts 4 and 5
Along with the sliding movement from the center of the partition area to the wall 1 side, the interlocking circulating means 15 and 17 are stretched around guide pulleys 14 and 16 to which the carts 4 and 5 are fixed. rotates clockwise and counterclockwise, respectively. Specifically, as the trolley 4 moves upward and to the right in the drawing, one of the interlocking circulating means 15 rotates clockwise. Along with this clockwise rotation, the free end side and lower end portion 6''b of the other accordion curtain 6b sequentially move toward the wall portion 1 side, and moreover, the folding of the pandagraph and the other accordion curtain As the upper end side 6'b of the curtain 6b is folded, it moves toward the wall 1 side at the same speed.Therefore, the other accordion curtain 6b maintains its drooping state and smoothly folds. Eventually, the other accordion curtain 6b is folded.Also, as the trolley 5 moves upward and to the right in the drawing, the other interlocking circulating means 17 moves counterclockwise. Along with this counterclockwise rotation, the free end side and lower end 6''a of one accordion curtain 6a
moves sequentially toward the wall 1 side, and moves at the same speed to the wall 1 side in accordance with the folding of the panda graph and the folding of the upper end side 6'a of one of the accordion curtains 6a. and transition.
Therefore, one accordion curtain 6a
are smoothly folded while maintaining the drooping state, and ultimately one accordion curtain 6a is folded. In this way, one and the other of the left and right accordion curtains 6a and 6b are respectively folded toward the wall portion 1 of the partition, whereby the accordion curtain 6 is fully opened and the partition is opened. Next, by turning off the drive device 10 (in the case of partial opening, it shall be turned off at a desired time during the process), the state shown in FIG. 2 where the above-mentioned open state is ensured is achieved. .

Also, when attempting to close the aforementioned open accordion curtain 6 (in principle, partially closing is almost the same), turn on the drive device 10 for the accordion curtain (if the drive device 10 is OFF) ) Then, when one of the driving circulating means 3 rotates counterclockwise in FIG. Specifically, in the drawing, the cart 4 slides to the left and the cart 5 slides to the right, and through this sliding transition, one and the other accordion curtain The panda graphs 6a and 6b are stretched one after another, starting from their free ends, and at the same time, the accordion curtains 6a and 6b on one side and the other are also stretched in a similar manner. .

In this folding process, the carts 4 and 5
As the partitioning area slides from the wall 1 side to the center part, the interlocking circulating means 15 and 17, which are stretched around the guide pulleys 14 and 16 to which the carts 4 and 5 are fixed, move. It rotates counterclockwise and clockwise, respectively. Specifically, as the trolley 4 moves upward and to the left in the drawing, one of the interlocking circulating means 15 rotates counterclockwise. Along with this counterclockwise circular movement, the free end side and lower end portion 6''b of the other accordion curtain 6b sequentially move toward the center side,
Furthermore, in accordance with the expansion of the panda graph and the expansion of the upper end side 6'b of the other accordion curtain 6b, it moves toward the center portion at the same speed.
Therefore, the other accordion curtain 6b
is extended smoothly while maintaining its drooping state, and ultimately the other accordion curtain 6b is extended. Also, as the trolley 5 moves upward and to the right in the drawing, the other interlocking circulating means 1
7 rotates clockwise. Along with this clockwise rotation, one of the accordion curtains 6
The free end side and the lower end portion 6''a of a gradually move toward the center side, and furthermore, the expansion of the panda graph and the one accordion curtain 6a
As the upper end side 6'a expands, it moves to the center side at the same speed. Therefore, one accordion curtain 6a is stretched smoothly while maintaining its drooping state, and ultimately one accordion curtain 6a is stretched. In this way, the left and right accordion curtains 6a and 6b are each stretched toward the center of the partition, thereby closing the accordion curtain 6 and creating a partition as shown in FIG. become a state. Then, by turning off the drive device 10 (in the case of partial opening, it shall be turned off at a desired time during the process), the state shown in FIG. 1 where the above-mentioned closed state is ensured is achieved. .

Note that "uniform speed" here means that the upper ends 6'a, 6'b and the lower ends 6''a, 6''b of one and the other accordion curtains 6a, 6b move at the same speed; This does not mean that the other accordion curtains 6a and 6b move forward and backward at the same speed.

"Effects of the Invention" As detailed above, the present invention operates the driving circulating means and the interlocking circulating means simultaneously, thereby simultaneously moving the upper end and the lower end of the accordion curtain. This has the effect that the free end side and the entire accordion curtain can be slid in a hanging state, and the accordion curtain can be opened and closed smoothly. Therefore, it is possible to avoid the conventional lateral vibration and the phenomenon that the lower end is mainly stirred by the wind.

In particular, in the present invention, since the driving and interlocking circulating means and the trolley work together, the operation is smooth and the accordion curtain can be opened and closed reliably and quietly. .
