2. Description of the Related Art In general, a shutter for partitioning indoors and outdoors or a partition for partitioning indoors has a winding method of a shutter as a shutter storage form when the shutter is opened to enable passage. Most widely used.

In addition to the winding method, a method of simply moving up and down like a background image of a stage for transferring the whole to another part of the soma, a method of rotating the whole as it is to open a passage, and There is a method of moving it to the left and right.

The storage form of these is determined at the same time by the mode of the installation purpose at the installation location of the shutter, the form and structure of the shutter corresponding to the installation purpose, and the like.

[0006]

As described above, the shutter mode is selected from a wide variety of modes depending on the purpose of installing the shutter. Generally, a shutter is immediately associated with the mode. But,
In buildings such as general buildings or warehouses, it is a shield that divides indoors and outdoors, is made of steel plate for crime prevention, disaster prevention, etc., and its single material is a corrugated shape that is an elongated rectangular original, As a means to make the long sides adjacent to each other, by means of a pivot-type articulated joint means that is basically bendable so that it can be bent,
There is a form in which one shutter is formed by connecting a large number of single materials, and the shutter is rolled up and unwound to open and close the shutter, and this form associated with the above is most widely used. That is why.

The use of a large number of strips of the steel plate exemplified above and the diversification of the winding method have some advantages, but also have some disadvantages. Especially, the structural difficulty of the shutter itself, material properties, and so on. One of the disadvantages of the installation is that it is heavy. In a building where this type of shutter is installed, it is necessary to plan to install the shutter from the beginning of construction of the building. There is a drawback that it is not possible to maintain the weight balance of the object itself, and therefore, because the action and effect of the shutter is large, it is impossible to retrofit the completed building without sufficient strength. It was supposed to be.

Further, other disadvantages of this type of shutter include every opening / closing operation, noise due to wind damage, and unbalanced left / right unbalance movement at the time of opening / closing operation, but the reliability is still higher than that of other models. Since it has high advantages in each of the other aspects such as installability, operability, and durability, it is a factor that has been widely used.

[0022]

The shutter structure is composed of a shutter body having a surface structure capable of shielding an area defined by a set frontage dimension to be opened and closed and a set height, and a groove pillar for guiding the shutter body.
In the shutter body, the size of the height range to be opened and closed is divided into an arbitrary set number, and the same or unequal size is defined as the short side and the set frontage dimension is defined as the long side. .

The groove pillar for guiding the shutter body includes an opening / closing section for moving the shutter up and down, and a portion extending in the lateral direction by providing a bent portion at a position where the opening / closing section has a set height as an upper limit. In the opening / closing section, the upper and lower sides of each unit body in the shutter body are joined to the upper and lower sides of the adjacent unit bodies to form a columnar shape and engage with the groove pillars to move up and down only the lowest unit body. When the driving unit body is configured to be urged to move and is in a closed state, by giving an ascending motion to the driving unit body, all the unit bodies connected to the upper part of the driving unit body are raised in an interlocking manner, and , When all of the units are raised and the shutter is opened from the state where it is closed, if the drive unit is lowered,
All the units connected to the drive unit show a falling state due to their own weight, but the set descent rate of the drive unit at the tip suppresses this, and all the units quietly expand the closing motion.

In this way, all the units of the shutter body move up and down in conformity with this operation by the ascending / descending movement of the lowest drive unit, and at the time of the rise, the highest unit is moved. The unit body reaches the bent part at the upper end of the straight groove column,
It is guided according to the configuration of the bent portion and advances to the storage portion.

In this accommodating portion, the advancing direction of the bent portion is changed, so that the gravity of the next lower lifting force is converted from the lower side to the side surface and the accommodating form of each unit body reaching the accommodating portion is unrelated. The unit rails are suspended from the combined storage rails, so that each unit body is stored in a horizontal shape.

Each unit body of the shutter body which operates as described above has a guide engaging piece composed of a shaft protruding horizontally from the upper and lower positions of its both sides or a runner rotatably attached to the shaft. The guide engaging piece is engaged with the groove of the groove pillar, the bent portion, and the rail in the accommodating portion so as to be slidable.

Further, on the upper and lower sides of all the unit bodies except the lower side of the lowest drive unit among the plurality of unit bodies, the installation direction of the accommodating portion provided so as to be continuous with the groove pillar is used as a standard. The inclined joint surface is provided with an inclined surface (inclination of about 45 degrees) in which the non-installed side is the upper side and the installed side is the lower side.

In this slanted joint surface, each unit body group moves upward by the ascending motion of the lowest drive unit body, and the upper guide engaging piece of the unit body located above is guided to the bent portion. When changing from a vertical motion to a horizontal motion while drawing an arc from the directly above motion, the lower guide engaging piece deviates from the ascending groove pillar, or moves to a lower dedicated lower track branched from the groove pillar. Even when being displaced, a displacement occurs between the vertical centerline of the displacement-oriented unit body and the centerline of the lower unit body, and the pushing action can continue even if the displacement phenomenon occurs. The form continues to push the unit body of the other side while continuing the slidable joint sliding contact with each other.

In this state, even if a part of the columnar relationship is in the joining state in the oblique joining surface, the joining operation between the tip unit body and the pushing-up unit body is continued due to the heavy lifting operation from below. At the same time as the relationship is broken, the row form starts and the leading unit that cannot completely enter the storage unit is in a state where gravity is cut off, so there is a phenomenon that it tries to descend due to its own weight, but there is Since the next unit body rises to, the self-propelled movement is blocked. At this time, when a part of the guide engagement piece engaged with the groove pillar is larger than the material thickness dimension of the unit body, the runners come into contact with each other, and the diameter of the runner is equal to that of the unit body. When the thickness is smaller than the thickness, the units are in surface contact with each other, and in any case, the ascending motion from the lower side is transmitted to the preceding unit,
The earliest unit body is sent into the storage unit, and subsequently the unit body that has been given the pushing motion is also sent into the storage unit by repeating the above-mentioned action, and in this way, all units other than the drive unit body are sent. The state in which the unit bodies are sent to the storage portion is changed from the previous column form to the row form, and the individual unit bodies are stored in a suspended state in which only the upper ends thereof are supported.

The above has described the engagement state of the shutter unit body and the groove pillar by the guide engagement piece provided on the shutter unit and the moving state thereof. These are the basic operations in the basic structure. A plurality of operation modes to be described in detail will be described.

In general, effective use as a shutter is most often provided for the purpose of shielding the indoor and outdoor areas from each other. Therefore, the storage unit connected to the groove pillar is necessarily provided indoors. Mostly.

In this case, the slanted shape of the joint side of the shutter body is an inclined state in which the indoor side is directed from the outdoor side, so that a shape particularly suitable for inviting rainwater is configured.

For the purpose of avoiding this situation, for the purpose of blocking water and running water at the joint surface part, the units are joined to each other, and the lifting action from below can be reliably transmitted to carry out the ascending movement. Under the first condition, based on this basic condition, the aim is to prevent rainwater from entering, but as a pre-stage to solve this problem, as described above, the unit body is a straight groove pillar. When moving from the upper end to the bent portion, the upper and lower sides of the guide engagement piece provided on one side surface of the unit body 2
Of the upper engagement piece and the lower engagement piece provided at the location, the upper engagement piece and the lower engagement piece are formed from the groove pillar that is still straight with respect to the lower engagement piece, that is, from the bending portion start point. It is necessary to perform an important pre-action to surely push out in the same direction as the side where the storage unit is installed from a position lower than the position where the joint piece is installed at an intermediate distance.

As described above, in order to achieve these objects, the guide engaging piece composed of two pieces of the upper engaging piece and the lower engaging piece is mounted and formed on one side of one unit pair. At the lower engaging piece mounting position, a guided piece having a different trajectory from the lower engaging piece is mounted at the same position, and a conversion guiding piece for changing the traveling direction at the set position is grooved to the guided piece. A branch point for a lower engagement piece is formed so as to act only on the guided piece, and the elevation of the unit up to the branch point depends on the upper engagement piece and the lower engagement piece. Movements other than the operation regulated by the gutter are suppressed.

In this way, each unit body in the range from the lowermost position of the straight portion of the groove pillar to the branch point where the above-mentioned conversion guide piece is provided is restricted to the vertical movement along the groove pillar. The ascending action is configured to be able to accept the movement by a pushing-up movement from below regardless of the joining form.

However, since the unit body at the time of rising is due to the pushing-up action from below as described above,
The movement of these movements is regulated by the engagement of the guide engagement piece and the groove pillar, but when the unit body acts to rotate about the lower engagement piece as an axis. There is a possibility that the upper engaging piece may deviate from the branch point to the outside of the groove pillar, and in order to prevent this, a protrusion prevention rail that can contact a part of the unit body is provided at a position below the branch point in the groove pillar. This is to prevent the turning action of the unit body that is to be generated and to occur, thereby preventing the upper engagement piece from deviating from the groove column.

Regarding the raising and lowering action of each of these unit bodies, it is not necessary to use all the upper and lower sides of the unit body as a transmitting portion for the raising and lowering motion, and it is sufficient that each unit body can be raised and lowered while maintaining a horizontal state. Therefore, the motion transmission part may be the both ends in the width direction where the most balanced state can be easily obtained, and in that case, one or both of the joint parts of the adjacent unit bodies are connected to the multi-centered cam side. Alternatively, when only one of them is a multi-center cam side, the relative side may be a roller.

As a condition for forming such a cam structure, when the cam formed on the lower side of the unit body is formed to project, the maximum projecting portion directed downward is defined as the center line in the vertical direction in the unit body plate thickness. On the side opposite to the installation side of the storage unit, and on the upper side of the unit body, a vertical centerline or an arbitrary set thickness from the centerline to the edge of the storage unit installation direction side. Should be (on the side).

According to the above, when the straight center lines of the upper and lower side surfaces (thickness direction) are broken when the upper unit body enters the bent portion, the cam sides to be joined together. (Even if one is a roller)
The distance between the center points of the lower unit bodies increases,
As a result, the upper and lower unit bodies, that is, the lower side of the upper unit body and the upper side of the lower unit body, are engaged mainly to prevent rainwater from entering. Even in the case of the relationship, the distance between the center points of the upper and lower units increases at the time when the two side surface centerlines are formed in a stepped manner, so that they are disengaged and the engaged relationship is released. It is also possible to facilitate the reverse action of engaging the separated forms.

Furthermore, if the male and female meshing relationships on the upper and lower sides of the upper and lower unit bodies can be firmly established, the upper engaging pieces of the guide engaging pieces provided on the side surfaces of the individual unit bodies can be established. The lower engaging piece can be omitted from among the lower engaging pieces and the lower engaging pieces. Therefore, the branch point for the lower engaging piece in the groove pillar is not necessary, and the upper or middle unit body can be removed from the upper unit or the intermediate unit unit at the time of raising each unit body. The bulging phenomenon that disturbs the columnar state that is assumed during the transmission of gravitational force can be prevented by connecting the feeding action of male and female.

The driving relationship governing the lifting and lowering of each unit body including the driving unit body exhibiting the above-described action is as follows: in the vicinity of the upper limit position of the straight groove columns facing each other, the total weight of all the unit bodies and By a drive source (motor) having a balanced balancer, a winding wire is hung down, and the lower end is fastened to the lowest drive unit or pivoted to the drive unit with respect to the laid wire. It is formed by engaging the above pulley.

In addition, in the vicinity of the set upper limit position of the groove pillar, an inward and outward movable latching piece that acts on the uppermost unit body is provided, and is vertically moved with respect to each unit body when the shutter acts. In order to maintain the immobility, the latching action can be released at the same time as these raising operations.

Furthermore, if the inclination angle of the rail in the storage section cannot be set to a large extent at the innermost end of the storage section, and the self-propelled action of oblique descent in the unit body cannot be sufficiently obtained. In addition, a contraction type coil spring is provided to enable each unit body to move downward in the descending operation of the drive unit pair.

[0044]

BEST MODE FOR CARRYING OUT THE INVENTION Next, referring to the drawings, an embodiment of the present invention will be described.
And a rail 2 that runs the shutter body 1.

The rail 2 supports both sides of the shutter body 1 and has a channel-shaped inner shape of an effective cross section which is free to travel, and this cross-sectional shape is the same as that of a known one. The groove pillar 2a having the same structure as the above, the bent rail 2b, and the housing rail 2c are formed in three parts.
Is a main part for opening and closing the shutter body 1, and is mainly installed vertically, and these installation forms are also the same as known examples, so that it is possible to remove it from the building when the shutter is opened, if necessary. However, since the configuration and the operation are not directly related to the gist of the present invention, detailed description thereof will be omitted.

The groove column 2 installed in the vertical direction has a height h set so as not to cause a hindrance to general traffic at its lowermost end when the shutter body 1 is lifted and opened. Extending in the lateral direction toward the inside of the building through the bend rail 2b formed by an arc-shaped rail that bends at an angle that is more than the right angle from the upper limit position of h, or a range where the right angle is the lower limit. The shutter body 1 is configured to be capable of continuous traveling by connecting to the tip of the storage rail 2c.

The storage rail 2c will be described in detail. It is desirable that the front end connecting to the bent rail 2b is low and the rear end is high. When each of the unit bodies 1a of 1 is engaged with the storage rail 2c, each unit body 1a is directed to a low position by its own weight and is self-propelled, that is, an angle smaller than that in the horizontal state is given. Although it is desired to incline, the tolerance may not be allowed for some reason in a building equipped with these shutter configurations, and in such a case, horizontal installation is forced, Auxiliary configurations by which the desired self-propelling action of each unit body 1a of the shutter body 1 can be expected will be described later. Therefore, the storage rails 2c can be installed either horizontally or inclined. Not intended to be constant.

The shutter body 1 to be engaged with the rail 2 has the effective height h of the groove pillar 2a as the total height, and the height h dimension is divided by an arbitrarily set number. The height dimension of each unit body 1a is the same as the height dimension of each unit body 1a, and the effective front width between the two groove columns 2a facing each other is the width dimension. Whether they are unequal or even, they are not limited as long as they are within the conditions such as the storage form and storage volume in the storage section described later and the allowable condition range.

When touching on the material system of each unit body 1a, it has a concept as a "plate" or a "frame",
Moreover, as long as the material has a certain degree of rigidity, and is a material that meets the purpose of erection as a shutter, for example, a wood-based material, a synthetic resin-based material, a metal-based single material, or a composite material thereof, or the like. The system and the material of these materials are not required, and the unification and unification of the materials for these materials are also optional.

In the unit body 1a using a plurality of these unit bodies, the unit body 1a located at the lowest position in the mounting order for engaging with the groove pillar 2a in the rail 2 is slightly different from the other unit bodies 1a in terms of equipment and the like. Named drive unit 1b,
Description will be made separately from the other unit bodies 1a.

Generally, the concept of installation of the "shutter" is strong as a boundary structure which divides the interior and the exterior of a building, and the shutter body is constructed on the basis of this concept.

Therefore, the structure is intended to shield rainwater, dust, noise, heat insulation, cold insulation, crime prevention, and disaster prevention. Among these defense systems, when one of the items of defense means is to prevent rainwater from entering, it is one of the structural requirements that must be given special consideration structurally.

For the purpose of shielding the inside and outside of a building, in the configuration of the rail 2 in the present application, it is premised that the storage section installed at the eccentric position above the groove pillar 2a is installed on the indoor side. It will be described below under the conditions.

The plurality of unit bodies 1a including the drive unit bodies 1b to be engaged with the rails 2 are engaged with the groove columns 2a when the shutters are closed, and all of them are arranged in a vertical line. It is closed when the upper and lower sides are joined together, but they are not provided with any means for connecting and joining each other, but are constructed so that they are joined by their own weight.

Basically, for example, a shaft that is projected in the horizontal direction from the side of all the unit bodies 1a including the drive unit body 1b, or a guide member formed by rotatably pivotally attaching a runner to the shaft. The joint piece 3 engages with all of the rails 2 and is mounted so as to be freely driven.

Although the driving unit 1b is not provided with its own running motion source, the motion transmitting means 4a such as a wire from the driving source 4 such as a motor having the upper limit position of the groove column 2a as the upper limit of gravity. It is connected to the drive unit 1b via. In this connection state, when the motion transmitting means 4a is directly fastened, and when the pulley 4b engaging the middle of the motion transmitting means 4a whose end is fastened to the upper end of the groove column 2a is mounted so as to be rotatable. In addition, the motion source 4 is provided with a balancer that balances the total weight of all the unit bodies 1a including the drive unit body 1b.

By doing so, when the driving unit body 1b is moved upward when the closed state is changed to the open state, the unit bodies 1 connected to the upper side of the driving unit body 1b are provided.
The pushing-up motion is transmitted to all of a under the joined state to rise as a unit, and at the time of lowering, each unit body 1a has a falling action due to its own weight. By the lowering operation of the regulation speed with respect to the driving unit body 1b, the dropping action is suppressed, and the driving unit body 1b is adapted to descend integrally with the descending speed of the driving unit body 1b.

At the upper and lower sides of all the unit bodies 1a and at the upper side of the drive unit body 1b, that is, at all of them adjacent to the other unit bodies 1a, the installation direction of the accommodating section rail 2c which is a part of the rail 2 to be engaged is set. Is an oblique joining surface 1c provided with an inclined surface having an angle of about 45 degrees and descending in the opposite direction from the opposite direction.

If two adjacent unit bodies 1a, 1a are brought into contact with each other on the oblique joint surface 1c and a pushing operation is applied from one unit body 1a to the other adjacent unit body 1a, the pushing operation is performed. As a condition for being driven in the direction in which the motion is directed, it is necessary to regulate the driven direction.

Therefore, a plurality of guide engaging pieces 3 made of, for example, a pulley-shaped runner, etc. are provided on one side surface of the unit pair 1a and the drive unit pair 1b so as to be adapted to the installation form of the rail 2. It is a thing.

When the guide engaging piece 3 is a pulley-shaped runner, the diameter dimension thereof is slightly larger than the thickness dimension of the unit body 1a, or a part of the circumference thereof is used. Each unit body 1 is made to project slightly from one surface of the unit body.
When "a" is hung on the storage section rail 2c, the surface contact between the unit bodies 1a is avoided.

Particularly, the section to be adapted is only the section of the groove column 2a installed in the longitudinal direction, and the sections other than the groove column 2a, that is, the sections of the bending section rail 2b and the storage section rail 2c are not covered by the sections. In the present invention on condition that the unit body 1a is hung from the rail, each unit body 1a rises,
The upper engagement piece 3a of the guide engagement piece 3 escapes from the upper limit of the straight groove column 2a, and the lower engagement piece 3b installed below at the same time as the engagement operation of the bending portion rail 2b escapes from the groove column 2a. There is a need.

For this reason, even if the heights of one unit body 1a are not the same, if a plurality of guide engaging pieces 3 are installed on the side surfaces, the installation position of the upper engaging piece 3a is set. In that case, the installation position of the lower engagement piece 3b is set by setting the gap dimension l thereof.

In this way, the gap dimension 1 between the upper engagement piece 3a of the guide engagement piece 3 and the lower engagement piece 3b is equal to the joining position of the upper end of the groove pillar 2a and the lower end of the bent rail 2b. The dimension is set to a position lower than the upper end of the groove column 2a, the set position is provided as a branch point 2d, and a part of the side wall is cut out so that the lower engagement piece 3b can be delivered from the groove column 2a. It is a thing.

From this branch point 2d, if necessary, a bent rail 2b1 and a storage rail 2 exclusively for the lower engaging piece 3b.
Providing c1 is also optional.

In order to prevent the upper engaging piece 3a from coming out from the cutout portion provided for letting out the lower engaging piece 3b, the groove pillar 2a is provided near or adjacent to the lower portion of the notch portion. The escape wall 2a1 is raised by raising the groove wall so that the side surface of the unit body 1a at the position between the upper engagement piece 3a and the lower engagement piece 3b can come into contact with the unit body 1a. It is intended to prevent the action of rolling to the notch side around the piece 3b. In some cases, it is also possible to suppress the protruding height of the escape prevention rail 2a1 by projecting an auxiliary tongue that can contact the escape prevention rail 2a1 from the unit body 1a side.

The guided piece 3c may be attached to the guiding engagement piece 3 described above. The guided piece 3c is inside the lower engaging piece 3b, that is, the unit body 1a, in the form in which the pulley engaging runner is pivotally attached to the shaft formed by projecting the lower engaging piece 3b from the unit body 1a side. At a position close to the side edge of the lower engaging piece 3b and having a pulley shape sharing the axis of the lower engaging piece 3b, having a diameter larger than that of the lower engaging piece 3b, and having the same locus as that of the upper engaging piece 3a. The requirement is that the locus of the lower engagement piece 3b be different.

In the groove pillar 2a corresponding to the case where the guided piece 3c is thus provided, the guided piece 3c is provided with the conversion guiding piece 2e on the non-accommodating portion side where the branch point 2d is set. It is provided at a position where it can come into contact with. Contrary to the above-described configuration, these may be configured such that the conversion guide piece 2e has a pulley shape and the guided piece 3c has a contact piece shape, or both have a pulley shape, and further both have a contact piece shape. Also, since the effects are basically the same, the respective forms are not limited to any of these.

It is also optional to configure the guide engaging piece 3 and the guided piece 3c as described above as a single derivative 3X and mount them on both sides of the unit body 1a separately configured.

As described above, when the guide engaging piece 3 and the guided piece 3c are made into one inductor 3X, the half body on the non-accommodating portion side at the lower end portion thereof is a long multicenter semicircular arc cam 3d. And a cam pushing portion 3e is formed on the half of the storage portion by pivotally rotatably attaching a cam 3e1 or a roller 3e2 corresponding to the semi-circular cam 3d to the upper end.

In this cam pushing portion 3e, the cam 3e1
In the case of, the derivative 3X attached to the adjacent unit body 1a
Since it is on the same side as the half arc cams 3d facing each other in
Although the joining is possible, when the roller 3e2 is used, since it is pivotally attached to the upper surface of the derivative 3X, it is different from the semi-circular cam 3d of the derivative 3X mounted on the adjacent unit body 1a. , The semi-circular cam 3d from the end of the semi-circular cam 3d in order to enable the joining.
And a side surface of the derivative 3X, which is located on the storage part side, is continuous to the upper end of the roller contacting edge piece 3e.
It is made by protuberating 3.

In this way, by mounting the derivative 3X in which both sides of the unit body 1a are formed separately from the guiding unit body 1a, the unit body 1a is bent from the longitudinal groove column 2a to the bent portion rail 2b.
When entering and displacing, due to the cam contact of each other, the adjacent unit bodies 1a, 1a which are in contact with each other exhibit a displacing action and a substantially separating action between the unit bodies. Since the lower side of the upper unit body 1a that is in contact with the upper side of the lower unit body 1a can be formed in an arbitrary shape, the above-mentioned oblique joint surface from the non-storage portion side to the storage portion side can be formed. It is possible to form a male-female mating connection without using 1c formation.

When the above-mentioned slanted joint surface 1c is used, the protection rate against the intrusion of rainwater is lowered when the slanted joint surface 1c is exposed to the outside, and therefore the flow path is directed downward for the purpose of avoiding this. An upper and lower chevron-shaped projection 1d and a lower side of the chevron-shaped recess 1e are formed on all sides to form a male-female meshing relationship, which is of course when the shutter is actuated, and is a transmission part of the ascending motion when the heavier is actuated from below. It is possible to expect the action and the swelling prevention action in the front-back direction, so that the attached derivative 3
The lower engaging piece 3b in X is unnecessary, and the upper unit body 1
At the same time as a starts engaging with the bent portion rail 2c and starts to be displaced, the squeezing motion is caused by the engagement of the chevron convex 1d and chevron recess 1e with the semicircular cam 3d and the cam pushing portion 3e of the guide 3X. The heavy action is automatically converted, and the meshing relationship is released at the same time when the cam action progresses,
At the same time that the meshing relationship is released, the guided piece 3c is configured to be removed in a direction of coming out of the groove column 2a by contact with the conversion guiding piece 2e.

In the shutter constructed as described above, each unit body 1a including the drive unit body 1b constituting the shutter body 1 is constructed by a "plate" or "frame body" having rigidity as a basic concept. Therefore, the height h of the shutter opening / closing opening to be set is divided into an arbitrary number to obtain the unit height of each unit body 1a. The volume formed by multiplying the thickness of the single body by the number of uses and the frontage dimension is used as the storage section volume, and the form such as the material of the unit body is selected according to the possible securing of the volume.

In the storage unit thus configured, when the storage unit rail 2c is not volumetrically allowed to form an oblique shape, and when it is difficult to move the unit body 1a forward, the storage unit rail 2c is not allowed.
A coil spring 2 for urging a pressing force directed to the connecting direction with the bent portion rail 2b as a pressing assisting structure at the end position of the
f is installed as needed.

Further, when the shutter body 1 is engaged with the groove pillar 2a of the rail 2 and is in the shutter closed state, a hooking piece 2g is provided for giving a non-operation to the uppermost unit body 1a, for example, opening and closing of the shutter. The operation is performed by an electromagnetic insertion / removal mode that works in conjunction with a switch operation based on an electric command.

The present invention is configured as described above, and in the conventional flexible shutter, the shutter is configured to be a single-size sheet by including a connecting piece having some mechanism. , The shutter to be configured is
Although it was necessary to manufacture based on each individual design to match the situation of the installation site, the present invention is at least unconnected and removable at the set height if the frontage is the same. Therefore, it is possible to perform planned production and inventory production as a single item without the need for individual design and production, and it is possible to install it by simply engaging the rails for each unit even during installation work, so it is a large scale. There is an effect that it is possible to deal with the right material in the right place by using each constituent body based on various constituent requirements without requiring a device such as a hoist.

Also, in the installation location, in the case of the conventional ceiling retractable type, although the ceiling structure and the lighting relation were often obstructed, the planar volume required for the accommodating portion of the present application can be reduced. Therefore, there is an effect that many advantages can be provided without obstructing the installation of other equipment.

As described above, since the work at the time of installation can be simplified, many specialized engineers are not required, and any number of persons can be appropriately trained without needing any advanced technology. There is an effect that can be installed.

As described above, the shutter can be used not only for the purpose of shielding the interior and exterior of a building but also for a partition shutter, a compartmental shutter, etc. without any selection of its application.
