When the shutter curtain reaches the fully open position by being wound on the winding shaft, the winding diameter of the shutter curtain on the winding shaft becomes maximum. As described above, when the shutter curtain has a plurality of concave portions and convex portions that are uneven in the shutter curtain thickness direction, and these convex portions are formed continuously in the opening and closing movement direction, these concave portions Since the convex part and the convex part are connected by the connecting part having an extension component in the thickness direction of the shutter curtain, when the shutter curtain is wound around the winding shaft, this connecting part is centered around the winding shaft. The shutter curtain resists bending deformation, and therefore, when the shutter curtain reaches the fully open position by being wound by the winding shaft, the maximum winding diameter of the shutter curtain on the winding shaft becomes large. Will end up.

Around the winding shaft, for example, a bracket provided with a bearing portion that supports the winding shaft, a shutter case for housing the shutter curtain wound by the winding shaft, and opening/closing movement of the shutter curtain If there is an object such as the upper end of the guide rail for winding, and the maximum winding diameter of the shutter curtain on the take-up shaft becomes large, the shutter curtain taken up by the take-up shaft will show such an object. May come into contact with.

An object of the present invention is to prevent a shutter curtain having a concave portion and a convex portion from contacting an object arranged around the shutter curtain even when the shutter curtain is wound by a winding shaft to have a maximum winding diameter. There is a shutter device that can do so.

In the shutter device according to the present invention, the shutter curtain that moves up and down in the vertical direction by winding and unwinding the winding shaft has a plurality of recesses and protrusions that are uneven in the shutter curtain thickness direction. In the shutter device having a portion formed continuously with the shutter curtain, the lower end portion of the shutter curtain is a seat plate, and the weight of the seat plate is a fully opened position when the seat is wound by the winding shaft. The shutter curtain having the maximum winding diameter by reaching the above condition has a weight that does not contact an object arranged around the shutter curtain.

According to this shutter device, the lower end portion of the shutter curtain having the concave portion and the convex portion is a seat plate, and the weight of the seat plate reaches the fully open position by being wound around the winding shaft. Since the weight of the shutter curtain does not come into contact with the objects placed around the shutter curtain when the winding diameter of The shutter curtain will not come into contact with the object placed at.

That is, in the shutter device according to the present invention, when the lower end portion of the shutter curtain is a seat plate, the weight of the seat plate is reduced by winding the shutter curtain wound around the winding shaft by tightening. It was invented paying attention to the fact that it acts downward on the shutter curtain, and even when the winding diameter of the shutter curtain in which the concave portion and the convex portion are formed is taken up by the take-up shaft, By increasing the weight of the seat plate, it is possible to prevent the shutter curtain from contacting or interfering with an object arranged around the shutter curtain.

In the above, as long as the shutter curtain has the above-mentioned plurality of concave portions and convex portions that are continuously formed in the opening and closing movement direction of the shutter curtain, the present invention provides a shutter curtain having an arbitrary form. It can be applied to the shutter device formed by.

In the shutter device of the example, at least a main part of the shutter curtain is formed by connecting a plurality of panels in a row in the opening/closing movement direction of the shutter curtain, and a plurality of concave portions and convex portions are provided on each of these panels. In addition, the panels adjacent to each other in the opening/closing movement direction of the shutter curtain are connected by the connecting means.

In the shutter device of another example, at least the main part of the shutter curtain is formed by one panel, and a plurality of recesses and protrusions are provided on all or substantially all of this panel.

Note that the main part of the shutter curtain is a part that is a part for opening and closing at least a part or most of the openings such as entrances and exits opened and closed by the shutter curtain. The suspension member attached to the upper end of the shutter curtain for connecting the curtain to the winding shaft is omitted.

Further, in the present invention, even if the winding diameter of the shutter curtain on the winding shaft is maximum as described above, the weight of the seat plate causes the shutter curtain to come into contact with an object arranged around the shutter curtain. In order to prevent interference, the entire seat plate may be made of the same material having a large weight, or a weight member may be arranged on the seat plate and the weight of the weight member may be reduced. Therefore, the weight of the entire seat plate may be increased. When arranging the weight member on the seat plate, the disposing location may be the front surface or the back surface of the seat plate, which is the outer surface of the seat plate, or the side surface or the lower surface.

Alternatively, a space portion may be provided inside the seat plate, and a weight member may be housed in the space portion so that the weight of the weight member increases the weight of the entire seat plate.

That is, when the weight member is housed in the space provided inside the seat plate in this way to increase the weight of the entire seat plate by the weight of the weight member, the seat plate and the weight member are made of different materials. Then, by forming the weight member with a material having a larger specific gravity than the material of the seat plate, the weight of the weight member increases the weight of the entire seat plate. For example, when the seat plate is made of aluminum, an aluminum alloy, or even plastic, the weight member is made of steel, lead, or the like, whereby the weight of the entire seat plate is sufficiently increased.

Further, in order to increase the weight of the entire seat plate by the weight of the weight member, it is preferable that the space portion has a length extending in the width direction of the shutter curtain. Also, since the shutter curtain can have a length extending in the width direction, the weight of the weight member can be increased.

When the space portion has a length extending in the width direction of the shutter curtain as described above, the space portion may be formed so as to penetrate in the width direction of the shutter curtain over the entire length of the seat plate. According to this, since the length of the weight member can be set to the length over the entire length of the seat plate, the weight of the weight member can be further increased.

When the space portion has a length extending in the width direction of the shutter curtain, even if the weight member is not housed over the entire length of the space portion, the winding shaft is wound to the fully open position. If the shutter curtain, which has reached the maximum roll diameter when reaching, does not come into contact with the objects placed around the shutter curtain due to the weight of the entire seat plate, the weight member is stored only in a part of the space. You may do it.

Further, in the present invention, the weight member may be simply stored in the space portion, or the weight member may be fixedly stored in the space portion by a fastener that can be operated from the outside of the seat plate. Good.

According to the latter, when the shutter curtain is opened and closed, the weight member can be prevented from floating in the space provided inside the seat plate by the fixing action of the fastener, and the fastener can be seated. Since it can be operated from the outside of the plate, the work for fixing the weight member to the space can be easily performed from the outside of the seat plate.

INDUSTRIAL APPLICABILITY The present invention described above can be applied to a shutter device installed at any place for any purpose, that is, the present invention is a shutter device for an entrance/exit for opening/closing an entrance/exit of a store, a warehouse, or the like. The present invention can also be applied to a garage shutter device, and further to a shutter device such as a window shutter device. Further, the present invention can be applied to both a manual shutter device and an electric shutter device.

According to the present invention, even if the shutter curtain having the concave portion and the convex portion is wound by the winding shaft to have the maximum winding diameter, the shutter curtain does not come into contact with the objects arranged around the shutter curtain. You can get the effect.

The work to do is shown. In the following description of this work, the rotating body 63 of the winding shaft 56 is moved to the central shaft 62 by operating the above-mentioned operating device for turning on the clutch 68 shown in FIG. 17 and driving the above-mentioned drive device 70. It is assumed that the predetermined work is performed by rotating the rotating body 63 around the center, but the clutch 68 is turned off and the rotating body 63 is rotated around the center shaft 62 (the suspension member 85 and the panel 10 are wound around the rotating body 63). After being turned, the operator may rotate the rotating body 63 about the central axis 62 via the suspending member 85 and the panel 10).

Before the guide rails 4 are attached to the building frame 3 such as the left and right walls of the doorway 2 of the garage, between the pair of left and right brackets 57 attached to the building frame such as the upper wall of the doorway 2 in FIG. Before the cover member 58 shown in the figure is bridged, a worker who has reached the vicinity of the bracket 57 by a ladder or the like attaches the central shaft 62 of the winding shaft 56 to the bearing portions 60 of the pair of left and right brackets 57 with the coupling tool 61. It is supported so that it cannot rotate, and then the operator joins the curved portions 85A of the plurality of suspension members 85 to the outer peripheral surface of the wheel member 65 that constitutes the rotating body 63 of the winding shaft 56 with screws or rivets. As shown in FIG. 21, the lower end portion of the hanging portion 85B of the suspending member 85 is attached to the above-mentioned mounting portions 57A and 57B of the pair of left and right brackets 57 in advance, and is attached to the lintel member.

Since the radius is the same as or substantially the same as the radius, and the bending length of the bending portion 85A is half or almost half of the entire circumferential length of the wheel member 65, by slightly expanding the bending portion 85A, The curved portion 85A can be easily brought into close contact with and fitted to the outer periphery of the wheel member 65, and the curved portion 85A after the fitting is half or substantially half of the entire circumference of the wheel member 65. Since it has a crossing length, the curved portion 85A can be coupled with a coupling tool such as a screw or a rivet over half or almost half of the entire circumference of the wheel member 65, whereby the wheel member is formed. A sufficiently long coupling length of the curved portion 85A with respect to the 65 can be ensured, and the curved portion 85A can be coupled to the wheel member 65 with great strength.

In addition, since the suspension base member 85 of the present embodiment has the length in the width direction of the shutter curtain 1, as shown in FIG. 21, the width dimension across the plurality of wheel members 65 is set. Therefore, by connecting the curved portion 85A of the suspension member 85 to the outer peripheral surface of the wheel member 65 with a coupling tool such as a screw or a rivet, the curved portion 85A of each suspension member 85 is divided into a plurality of portions. It is performed by straddling the wheel member 65. However, the suspension base member may have a short width in the width direction of the shutter curtain 1, and the curved portion of each suspension base member may be coupled to the outer peripheral surface of one wheel member.

Next, the operator selects the uppermost panel among the plurality of panels 10 that are continuously arranged in the opening/closing movement direction of the shutter curtain 1 to form the main part of the shutter curtain 1 excluding the hanging member 85 and the seat plate 8. The first hook portions 14 of the upper end portion of 10 are fitted from above onto the hook portions 86 of the lower end portion of the suspending member 85, and the hook portion 86 of the suspending member 85 and the first hook portion of the uppermost panel 10 are respectively fitted. 14 and 14 are connected by rivets as in the case of connecting the panels 10 to each other. After this, the operator drives the above-mentioned drive device 70 by operating the above-mentioned operating device, and thereby causes the rotating body 63 of the winding shaft 56 to rotate in the reverse direction with respect to the central shaft 62. The hanging portion 85B of the member 85 is wound up by the rotating body 63, and the second hook portion 15 at the lower end portion of the uppermost panel 10 and a portion slightly above the second hook portion 15 are provided with the lintel member 78, Most of the uppermost panel 10 is wound up by the rotating body 63, leaving the unwound portion which is projected below 79 and not wound around the rotating body 63.

Since the hook portion 35 of the seat plate 8 has the same shape as the first hook portion 14 provided as an upper end hook portion on each panel 10, the seat plate 8 is attached to the lowermost panel 10. The work for connecting the panels can be performed with the same work content as the work for connecting the uppermost panel 10 to the suspension member 85 and the work for connecting the respective panels 10 to each other. It is also possible to facilitate the mounting work of No. 8.

Also in this embodiment, as described above, each time the plurality of panels 10 are connected to the upper member, the rotating body 63 of the winding shaft 56 is rotated with respect to the central shaft 62, and these panels are rotated. Rather than winding 10 by the winding shaft 56, after all the panels 10 are vertically arranged, the rotating body 63 of the winding shaft 56 is rotated with respect to the central shaft 62 to wind these panels 10. The shaft 56 may be wound up.

After attaching the seat plate 8 to the second hook portion 15 at the lower end portion of the lowermost panel 10 as described above, the operator further operates the operating device described above to operate the rotating body 63 of the winding shaft 6.

FIG. 34 shows a state in which both widthwise ends of the shutter curtain 1 in which a main part is formed by connecting the respective panels 10 are slidably inserted into the left and right guide rails 204. . As shown in FIG. 34, the retaining members 200 arranged on both ends of the panel 10 in the width direction of the shutter curtain 1 are provided on both sides in the thickness direction of the panel 10 inside the garage. As shown in FIG. 32 and FIG. 33, a plurality of protrusions 12 provided on each panel 10 are attached to the panel 10 on the side surface. Of these, the second and fourth convex portions 12 from the bottom are the surfaces on the inner side of the garage.

The retaining member 200 protrudes outward from a base portion 201 coupled to the panel 10 and an end surface in the width direction of the shutter curtain 1 in the panel 10, and extends from the base portion 201 to both sides in the thickness direction of the shutter curtain 1. The projecting portion 202 has a T-shape in a plan view including the projecting projecting portion 202, and the projecting portion 202 is a first locking portion 202A extending to one side in the thickness direction of the shutter curtain 1. And a second locking portion 202B extending to the other side. Of the surfaces on both sides in the thickness direction of the panel 10, a reinforcing member 203 having a thickness larger than that of the above-mentioned thin metal plate which is the material of the panel 10 is arranged on the surface on the outside of the garage described above. The reinforcing member 203 and the base portion 201 are attached to the panel 10 by being fastened together with screws 205 which are coupling tools.

Therefore, even if the panel 10 is formed of a thin metal plate, the retaining member 200 in which the thickness of the base portion 201 is larger than that of the thin metal plate that is the material of the panel 10 is used as the retaining member. The reinforcement member 203 sandwiching the panel 10 together with 200 can be reinforced and attached to the panel 10, and the attachment strength can be increased.

Further, FIG. 34 has a length extending in the up-down direction which is the opening and closing movement of the shutter curtain 1 while meandering in the thickness direction of the shutter curtain 1 following the shapes of the concave portions 11 and the convex portions 12 of the panel 10. Also, the first belt member 21 and the second belt member 22 which are the contact preventing members described above are also shown. In the present embodiment, the reinforcing member 203 is the width direction of the first belt member 21 and the shutter curtain 1. Are mounted side by side on the panel 10. Further, in the present embodiment, a part of the base portion 201 of the retaining member 200 is arranged so as to overlap at a position in the width direction of the second belt member 22 and the shutter curtain 1, and this overlapping state prevents retaining. The base portion 201 of the member 200 is in a state of being sandwiched between the panel 10 and the second belt member 22, and the base portion 201, the first belt member 21, and the second belt member 22 are stoppers arranged at the above-mentioned overlapping positions. The staple 23, which is a tool, is joined to the panel 10 in a co-tightened state. For this reason, the stopper for attaching the retaining member 200, the first belt member 21, and the second belt member 22 to the panel 10 is common.

Therefore, the retaining member 200 and the first and second belt members 21 and 22 can be joined to the panel 10 together by the staples 23 of the stoppers in a tightened state, so that the staples 23 can be commonly used.

Also in this embodiment, when the retaining member 200 and the first and second belt members 21 and 22 are attached to the panel 10 by driving the staple 23, the staple 23 is arranged by increasing the driving load of the staple 23. The surfaces of the first and second belt members 21 and 22 at the punctured portions are recessed, whereby the base portion of the staple 23 on the first belt member 21 side and the bent portion of the staple 23 on the second belt member 22 side. And may be positioned closer to the panel 10 than the surfaces of the belt members 21 and 22 where the staples 23 are not arranged.

When it is difficult to drive the staple 23 directly into the base portion 201 of the retaining member 200, the first belt member 21, and the second belt member 22, the base portion 201 of the retaining member 200 and the first belt are preliminarily set. The lower hole may be formed in the member 21 and the second belt member 22 and the staple 23 may be driven in, or the lower hole may be formed in the panel 10.

The above attachment of the retaining member 200 to the panel 10 is performed in the shutter device production factory in which the respective panels 10 are manufactured, similarly to the first and second belt members 21 and 22. As in the above-described embodiment, the main part of the shutter curtain 1 is formed by being continuously installed in the opening/closing movement direction of the shutter curtain at the installation site of the shutter device.

Inside the guide rail 204 shown in FIG. 34, there is provided a pair of partition wall portions 206 and 207 facing each other with a gap in the thickness direction of the shutter curtain. The interiors of the guide rails 204 are partitioned by the portions 206 and 207 into a first chamber 208 inside the shutter curtain 1 in the width direction and a second chamber 209 outside the shutter curtain 1 in the width direction. A space S between 207 is smaller than the protruding amount of the protruding portion 202 of the retaining member 200 to both sides in the thickness direction of the shutter curtain 1. The base portion 201 of the retaining member 200 is inserted through the gap S from the inner side to the outer side in the width direction of the shutter curtain 1, and the protruding portion 202 of the retaining member 200 is housed in the second chamber 209. The second belt members 21, 22 and the reinforcing member 203 are housed in the first chamber 208. Therefore, when the shutter curtain 1 is guided by the guide rails 204 and moves up and down in the vertical direction, the base portion 201 moves up and down in the gap S, and the projecting portion 202 moves up and down in the second chamber 209. The first and second belt members 21, 22 and the reinforcing member 203 move up and down in the first chamber 208.

The thickness dimension of the reinforcing member 203 is the first belt member attached to the same surface of the panel 10 on both sides in the thickness direction of the shutter curtain 1 as the surface to which the reinforcing member 203 is attached. Since the thickness of the reinforcing member 203 is equal to or smaller than the thickness of 21, the reinforcing member 203 contacts the inner surface of the guide rail 204 when the shutter curtain 1 is opened and closed. This is prevented by the member 21.

Similar to the first and second belt members 21 and 22 described with reference to FIG. 7 and the like, the belt member 350 attached to the upper member 310 with staples or adhesives has the longitudinal end portion of the upper member 310 inserted. This is for allowing the shutter curtain 1 to move in the vertical direction without the upper member 310 coming into direct contact with the inner surface of the guide rail 4 to be formed.

As described above, the main part of the shutter curtain 1 is formed by arranging a plurality of panels 10 in a row in the vertical direction, and each of the panels 10 has a plurality of projections and depressions in the thickness direction of the shutter curtain 1. The concave portions 11 and the convex portions 12 are continuously formed in the vertical direction, and these concave portions 11 and the convex portions 12 are connected to each other by the connecting portions 13 shown in FIG. 7 and the connecting portions 13′, 13′ shown in FIG. Since the connecting portions 13, 13 ′ and 13 ″ are connected to each other with a component that extends in the thickness direction of the shutter curtain 1, the shutter curtain 1 is shown in FIG. 1. When the take-up shaft 6 or the take-up shaft 56 shown in FIG. 16 is taken up, the connecting portions 13, 13′, 13″ of the shutter curtain 1 are curved and deformed around the take-up shafts 6, 56. Resist doing. Therefore, when the shutter curtain 1 reaches the fully open position by being wound by the winding shafts 6 and 56, the maximum winding diameter of the shutter curtain 1 on the winding shafts 6 and 56 is The shutter is larger than a normal slat type shutter device formed by arranging a large number of slats vertically.

Therefore, in the seat plate 308 according to the embodiment of FIG. 38, the entire weight of the seat plate 308 is made heavy, whereby a large downward load is applied to the shutter curtain 1 and the winding shafts 6 and 56 are wound. By winding up the shutter curtain 1 thus wound, the winding diameter of the shutter curtain 1 around the winding shafts 6 and 56 is reduced.

Then, in order to increase the overall weight of the seat plate 308, in the embodiment of FIG. 38, the above-described space portion 311 having a large vertical dimension is provided inside the upper member 310 which is a member forming the seat plate 308, A weight member 370 is housed in this space 311. The upper member 310 and the lower member 320 that form the seat plate 308 are made of aluminum or an aluminum alloy as described above, and the end member 330 that forms the seat plate 308 is made of plastic, On the other hand, since the weight member 370 is made of steel, stainless steel, or lead, the seat plate 308 and the weight member 370 are made of different materials, and the weight member 370 is made of the material of the seat plate 308. Is also formed of a material having a large specific gravity. Accordingly, the weight of the seat plate 308 itself, excluding the weight member 370 to facilitate handling, is reduced by the aluminum or aluminum alloy and the plastic described above, while the weight of the seat plate 308 including the weight member 370 is reduced. The overall weight is sufficiently heavy.

The weight member 370 is fixed in the space 311 of the upper member 310 by the screw 323 described above. That is, as shown in FIG. 40, the weight member 370 is formed with a female screw hole 370A into which the screw 323 is screwed, and the female screw hole 370A can be rotated from the outside of the seat plate 308. By screwing in the screw 323, the weight member 370 is housed and fixed in the space 311 by the screw 323 serving as a fastening tool.

The work of housing and fixing the weight member 370 in the space 311 may be performed in a factory where the seat plate 308 is manufactured, or may be performed in a construction site where the shutter device is installed. The head of the screw 323 faces the inside of the garage in which the shutter device is installed.

In FIG. 43, the winding shaft around which the shutter curtain 1 is wound is the winding shaft 6 of FIG. 1, and the winding shaft 6 is provided on brackets 367 arranged on both sides in the width direction of the shutter curtain 1. It shows an embodiment supported by a bearing 360. A flange portion 368 extending inward in the width direction of the shutter curtain 1 is provided on the outer peripheral portion of the bracket 367 of this embodiment, and the rear surface portion 368A of the flange portion 368 is installed with the shutter device of this embodiment. It is attached to a skeleton body 369 such as a wall of a garage by a fastener 380.

The flange portion 368 has a large extension inward in the width direction of the shutter curtain 1. Therefore, when the shutter curtain 1 is viewed from the front as shown in FIG. It is a part overlapping with 368.

Further, in the embodiment of FIG. 43, the guide rail 4 that guides the opening and closing movement of the shutter curtain 1 is arranged at a position close to the skeleton 369. For this reason, if the weight of the shutter curtain 1 is reduced, the maximum winding diameter of the shutter curtain 1 on the winding shaft 6 when the shutter curtain 1 is wound around the winding shaft 6 and reaches the fully open position. As a result of the bulging of the shutter curtain 1 due to the resistance of the above-mentioned connecting portions 13, 13', 13'', the diameter becomes close to the frame 369 beyond the position when the guide rail 4 is extended upward, and this shutter curtain 1 may come into contact with the back surface portion 368A of the flange portion 368 of the bracket 367 or the head portion 380A of the fastener 380. That is, there is a possibility that the shutter curtain 1 may come into contact with or interfere with an object arranged around the shutter curtain 1 wound around the winding shaft 6.

However, in the present embodiment, since the weight of the weight member 370 makes the weight of the seat plate 308 heavy as described above, the shutter curtain 1 is wound by the winding tightening effect due to this downward load. As shown in FIG. 43, the maximum winding diameter of the shutter curtain 1 when the shutter curtain 1 is wound up by the take-up shaft 6 and reaches the fully open position is shown in FIG. It is possible to set the winding diameter D so as not to contact the head portion 380A.

Further, in the present embodiment, the space portion 311 provided inside the upper member 310 of the seat plate 308 for housing the weight member 370 has the length in the width direction of the shutter curtain 1. Since the seat plate 308 and the upper member 310 are formed so as to penetrate in the width direction of the shutter curtain 1, the maximum length of the weight member 370 is the same as or substantially the same as the total length of the seat plate 308 and the upper member 310. Therefore, the entire weight of the seat plate 308 including the weight member 370 can be sufficiently increased.

When the weight member 370 having a large weight is not required, the length of the weight member 370 is not made the same as or substantially the same as the entire length of the seat plate 308 and the upper member 310 as described above, but the shutter curtain. The weight member 370 may be housed in only a part of the space 311 having a length of 1 in the width direction.

That is, according to the present embodiment, the space portion 311 has a long dimension in the width direction of the shutter curtain 1. Therefore, the space portion 311 is provided in accordance with the application of each shutter device installed at various installation sites. The weight of the weight member 370 to be stored can be changed and adjusted by setting the length dimension of the weight member 370.

When the weight member 370 is stored only in a part of the space 311, as described above, in order to improve the left-right balance of the entire weight of the seat plate 308 including the weight member 370, for example, the weight member 370 is used. Is formed by two dividing members each having the same or substantially the same length dimension, and these dividing members are arranged at the same or substantially the same distance from the left and right openings of the space 311. Furthermore, the weight member 370 may be formed by two such dividing members and one or a plurality of third dividing members, and the third dividing member may be formed between the two dividing members. You may make it arrange|position in a central position.

Further, according to the present embodiment, the weight member 370 is stored in the space portion 311 by being fixed by the screw 323, so that even if the shutter curtain 1 is opened and closed in the vertical direction, the weight member 370 is allowed to move in the space portion 311. Can be prevented.

Further, the screw 323 serves as a fastener for fixing the weight member 370 to the space portion 311, and since the screw 323 can be rotationally operated from the outside of the seat plate 308, the weight is fixed by the screw 323. The work of fixing the member 370 to the space 311 can be easily performed from the outside of the seat plate 308.

Further, the screw 323 also serves as a coupling tool for coupling the upper member 31 and the lower member 320, each of which is a constituent member of the seat plate 308, so that the screw 323 can be used in common. ..

It is designed to hang vertically. In other words, the outer peripheral portion of the shutter curtain 1 having the maximum winding diameter D is present at a vertically or substantially vertically extended position above the guide rail 4. According to this, the shutter curtain 1 wound on the winding shaft 6 and having the maximum winding diameter D is the rear surface portion 368A of the flange portion 368 of the bracket 367 which is an object arranged around the shutter curtain 1. Also, contact with the head 380A of the fastener 380 can be more effectively eliminated.

In the embodiment of FIG. 44, the shutter curtain 1 having the maximum winding diameter D hangs down toward the guide rail 4 while approaching the body 369. In other words, the outer peripheral portion of the shutter curtain 1 having the maximum winding diameter D does not exist in the vertically or substantially vertically extended position above the guide rail 4, and the outer peripheral portion is located above the guide rail 4. It exists on the side away from the skeleton body 369 with respect to the vertical or substantially vertical extension position thereof. According to this, the shutter curtain 1 wound up on the winding shaft 6 and having the maximum winding diameter D may come into contact with the back surface portion 368A of the flange portion 368 of the bracket 367, the head portion 380A of the fastener 380, or the like. Can be eliminated even more effectively.

Note that in the embodiment of FIGS. 43 and 44 regarding the positional relationship between the outer peripheral portion of the shutter curtain and the guide rail when the winding diameter is the maximum, the seat plate is not the seat plate of the embodiment of FIG. The maximum winding diameter of the shutter curtain shown in FIGS. 43 and 44 can also be implemented when it is a diameter that is not wound by the entire seat plate including the weight of the weight member.

In FIG. 45, the seat plate 308 and the lowermost panel 10 among the panels 10 forming the main part of the shutter curtain 1 are connected by an intermediate member 351 different from the intermediate member 341 of FIG. 38. The morphology is shown. Similar to the panel 10, this intermediate member 351 formed of a metal plate material has a hook portion 352 that is locked from above to the above-described locked portion 388 of the locked panel 388 of the lowermost panel 10, The hook portion 352 includes a first horizontal portion 352B extending horizontally or substantially horizontally in the thickness direction of the shutter curtain 1 from a base portion 352A joined to the upper member 310 of the seat plate 308 by rivets 342, and the first horizontal portion 352B. From the upwardly extending portion 352C, which extends vertically or substantially vertically upward from the upward extending portion 352C, and extends horizontally or substantially horizontally in the thickness direction of the shutter curtain 1 from the upwardly extending portion 352C in the opposite direction to the first horizontal portion 352B. It comprises a second horizontal portion 352D and a downward extension portion 352E extending downward from the second horizontal portion 352D.

By locking the hook portion 352 of the intermediate member 351 to the upwardly inclined portion 388B of the locked portion 388 of the lowermost panel 10 from above, the base portion 388A of the locked portion 388 and the downward extension of the hook portion 352. By overlapping the portion 352E in the thickness direction of the shutter curtain 1 and connecting the base portion 388A and the downward extending portion 352E with the rivet 353 which is a blind rivet, the panel 10 and the intermediate member 351 in the lowermost stage are connected. The seat plate 308 is connected to the lowermost panel 10 via the intermediate member 351.

In the embodiment of FIG. 38, in order to reduce the maximum winding diameter D of the shutter curtain 1 which has reached the fully opened position by winding the winding shaft 6, the weight of the weight member 370 makes the entire weight of the seat plate 308 heavy. The reduction of the maximum winding diameter D of the shutter curtain 1 can be achieved not only by the technical means according to the embodiment of FIG. 38 but also by the following technical means.

A first technical means is to increase the weight of the lowermost panel among the plurality of panels forming the main part of the shutter curtain. In order to realize this, the weight of the lowermost panel itself may be heavier than the weight of other panels, or a weight member may be attached to the lowermost panel.

A second technical means is to make the shape of each panel in its natural state into a curved shape in which the side wound by the winding shaft is on the inside. In order to achieve this, each panel itself may be given a habit of being curved and deformed, or the belt member described in FIG. The panel may be attached and attached, and the tension of the belt member may cause the shape of each panel in a natural state to be curved and deformed so that the side wound by the winding shaft is inside.

This technical means can also be applied to the case where the main part of the shutter curtain is not formed by connecting a plurality of panels in series but is formed by a single panel having a large vertical dimension.

A third technical means is to form a shutter on a take-up shaft by not forming a concave portion and a convex portion on a plurality of panels forming a main part of a shutter curtain and making these panels flat panels made of flat plate materials. The maximum winding diameter of the curtain is reduced, and a pair of left and right guide rails that guide the opening and closing movement of the shutter curtain are provided with shutter curtain guide passages with concave and convex portions that are smoothly connected in curved shapes. Thus, when the shutter curtain is guided by the guide passage and closed and moved, concave and convex portions having irregularities in the thickness direction of the shutter curtain are formed on the shutter curtain.

Note that this technical means can also be applied to the case where the main part of the shutter curtain is not formed by the continuous arrangement of a plurality of panels but is formed by one panel having a large vertical dimension.

A fourth technical means is to provide a curved guide portion curved toward the winding shaft on a pair of left and right guide rails that guide opening and closing movements of the shutter curtain, and the shutter guide is operated by the curved guide portion. It is to wind by this winding shaft while gradually approaching the winding shaft. An example of implementing this is to install a retaining member at the end of the shutter curtain in the width direction to prevent the shutter curtain from slipping out of the guide rail, and to lock the guide rail slidably. By the action of the member and the action of the curved guide portion, the shutter curtain is wound by the winding shaft while gradually approaching the winding shaft.

Note that this technical means can also be applied to the case where the main part of the shutter curtain is not formed by the continuous arrangement of a plurality of panels but is formed by a single panel having a large vertical dimension.

A fifth technical means is to rotatably connect panels that are vertically arranged to form a main part of the shutter curtain. In this connection structure, for example, the curl portion is formed at the lower end portion of the upper panel and the curl portion is formed at the upper end portion of the lower panel, and the curl portions are rotatably engaged with each other. Can be realized by

The technical means described above (including the technical means shown in FIG. 38) can be implemented individually, or can be implemented by combining a plurality of technical means.

Further, a winding spring for winding and unwinding the shutter curtain for opening and closing the shutter curtain in the up-down direction has a return spring when the shutter curtain is closed and moved like the winding shaft described in FIG. When a force is accumulated and the opening movement of the shutter curtain is used as a winding shaft equipped with a return spring that is used by using this return spring force as an auxiliary force, the magnitude of the spring force of this return spring is set. In the full opening and closing movement process from full closing to full opening of the shutter curtain, even when the shutter curtain is lifted by supporting the seat plate from below, It is preferable to set the size such that it is not unwound or hardly unwound or only slightly unwound by the restoring force to return to the state, and the total weight of the seat plate including the weight member is set to the shutter curtain. When it reaches an intermediate position between fully closed and fully open, the shutter curtain is opened by the return spring force of the return spring and the shutter curtain by the weight of the portion of the shutter curtain that is unrolled from the winding shaft. It is preferable to set the weight so that the closing movement force of the curtain is equal or substantially equal.

In addition, the characteristic of the spring force of the return spring, which changes when the winding shaft rotates forward and backward for winding up the shutter curtain, is shown in the shutter curtain including the seat plate on which the weight member is arranged. It is preferable that the weight of the portion hanging from the take-up shaft corresponds to the characteristic that changes when the take-up shaft rotates forward and backward for winding the shutter curtain.

Furthermore, at various installation sites where the left and right dimensions and vertical dimensions of openings such as doorways that are opened and closed by shutter curtains are different, the shutter device can be appropriately installed according to each application required at the installation site. Therefore, information about the spring force of the plurality of return springs (for example, the spring coefficient and the number of turns of the spring, the spring force at the time when the shutter curtain is fully opened, etc.) and information about the total weight of the seat plate including the weight member are provided, for example. In a shutter device whose installation site and application are determined, the spring force of the return spring and the total weight of the seat plate including the weight member can be easily and quickly determined in a matrix. You may be able to.
