The dimension is smaller than the vertical dimension H2 between the lower end portion 4B of 4 and the upper end of the connecting member 24. Further, the dimension H1 is a portion of the shutter curtain 1 reaching below the lower end portion 4B of the take-up shaft 4 of FIG. 4, and is mounted on the second mounting member 32 of the transport carriage 20. The dimension is smaller than the vertical dimension H3 between the lower end portion 1D of the shutter curtain 1 and the upper end of the connecting member 24.

Next, the work to be carried out for receiving the take-up shaft 4 by the two brackets 3 shown in FIG. 2 will be described.

In FIG. 9, the transport carriage 20, the attachment platform 40, and the forklift vehicle are shown in order to carry out the work of receiving the take-up shaft 4 mounted on the first mounting member 31 of the transport carriage 20 by the two brackets 3. It shows the case where 60 and 60 are arranged side by side on the floor 11 of the building where the shutter device is installed, and the shutter curtain 1 wound in a spiral shape is placed on the second mounting member 32 of the transport carriage 20. ing. The fork 61 of the forklift vehicle 60 moves up and down along the guide member 63 by a driving means such as a cylinder or a chain. Further, the fork 61 has an L-shape or a substantially L-shape including a vertically extending portion 61A extending in the vertical direction and a front extending portion 61C extending forward from the lower end of the vertically extending portion 61A via the connecting portion 61B. It is in the shape of a letter.

In FIG. 10, by lowering the fork 61 and advancing the forklift vehicle 60, the forward extending portion 61C of the fork 61 is inserted into the tubular member 44 of the attachment base 40 placed on the floor 11. As a result, the state when the attachment table 40 is set on the fork 61 is shown, and FIG. 11 is a plan view at this time.

Further, FIG. 12 shows an enlarged relationship between the tubular member 44 and the fork 61 at this time, FIG. 12A is a plan view, and FIG. 12B is a side view. A notch 44C for fitting the vertically extending portion 61A of the fork 61 is formed on the upper surface of the rear end of each tubular member 44, and is formed on the rear end of each tubular member 44. An escape prevention means 64 is provided that blocks a part of the opening 44D. The slip-out preventing means 64 includes a bolt 65 in which the shaft portion 65A crosses the opening 44D, and a nut 66 screwed to the end of the shaft portion 65A outside the tubular member 44. The portion 65A closes a part of the opening 44D on the rear side of the connecting portion 61B that bends and connects the vertically extending portion 61A and the front extending portion 61C of the fork 61 inside the tubular member 44. I'm out.

Therefore, after setting the attachment base 40 on the fork 61, if the pull-out preventing means 64 including the bolt 65 and the nut 66 is set on the tubular member 44, the tubular member 44 will pull out forward from the forward extending portion 61C of the fork 61. Is blocked by the shaft portion 65A of the bolt 65 of the pull-out preventing means 64 coming into contact with the connecting portion 61B of the fork 61. Therefore, the attachment base 40 is set on the fork 61 in a stable state by preventing it from falling off. Can be done. Further, since the pull-out preventing means 64 is composed of a bolt 65 and a nut 66 that can be separated from the tubular member 44, the attachment base 40 can be forked 61 by separating the bolt 65 and the nut 66 from the tubular member 44. It can also be removed from.

In FIG. 13, the fork 61 of the forklift vehicle 60 in which the attachment base 40 is set as described above is slightly raised, and then the forklift vehicle 60 is moved forward toward the transport carriage 20 or in FIG. 3. The transport trolley 20 equipped with the handle member 33 shown in FIG. 4 is moved forward by the operator toward the attachment pedestal 40 by the handle member 33, so that the two left and right tubular members 44 of the attachment pedestal 40 are transferred to the transport trolley. The state of being inserted under the take-up shaft 4 mounted on the first mounting member 31 of 20 is shown, and this insertion work is performed on the transport carriage 20 for mounting the take-up shaft 4. This is performed until the positions of the pair of first mounting members 31 provided and the positions of the pair of third mounting members 57 provided on the attachment table 40 match. FIG. 14 is a cross-sectional view taken along the line S14-S14 of FIG. As described above, since the dimension L1 in FIG. 7 is smaller than the dimension L2 in FIG. 4, the above-mentioned insertion work is performed on the left and right two tubular members on the attachment table 40 as shown in FIG. 44 can be inserted between the two base members 21 provided on the left and right sides of the transport carriage 20.

Further, since the dimension H1 in FIG. 7 is smaller than the dimensions H2 and H3 in FIG. 4, as shown in FIG. 14, the third mounting member 57 provided on the attachment table 40 is attached to the transport carriage 20. The lower side of the lower end 4B of the take-up shaft 4 mounted on the first mounting member 31 provided, and the upper side of the connecting member 24 connecting the two base members 21 of the transport carriage 20. In, the above-mentioned insertion work can be performed by invading. Further, as shown in FIG. 14, the first mounting is provided on each of the two base members 21 of the transport carriage 20, and the two are arranged apart from each other in the axial direction of the take-up shaft 4. The distance between the members 31 is larger than the distance between the third mounting members 57, which are provided on each of the two tubular members 44 of the attachment base 40 and are arranged two apart in the axial direction of the take-up shaft 4. Due to its large size, the above-mentioned insertion work can be performed by inserting the two third mounting members 57 of the attachment base 40 between the two first mounting members 31 of the transport carriage 20.

FIG. 15 shows a case where the attachment table 40 is lifted by the fork 61 by raising the fork 61 of the forklift vehicle 60 after performing the above-mentioned insertion work. By this lifting work, the take-up shaft 4 mounted on the first mounting member 31 of the transport carriage 20 is delivered to the third mounting member 57 of the attachment base 40. Therefore, in the present embodiment, the transport trolley 20 is a transfer pedestal for delivering the take-up shaft 4 to the attachment pedestal 40, and the attachment pedestal 40 is for receiving the take-up shaft 4 from the transport trolley 20. It is a receiving stand.

Then, in order to deliver the take-up shaft 4 mounted on the first mounting member 31 of the transport carriage 20 to the third mounting member 57 of the attachment base 40, the fork 61 for raising the attachment base 40 is used. The forklift vehicle 60 provided with the above is the lift device according to the present embodiment.

After performing the above work, the forklift vehicle 60 is driven to the installation site of the shutter device, and as shown in FIG. 16, the fork 61 is further raised to be mounted on the third mounting member 57. As a result, the take-up shaft 4 mounted on the attachment base 40 is located at a position lower than the height position of the brackets 3 arranged on the left and right sides of the skeleton 8 which is the immovable member of the building shown in FIG. Lift up to. In FIG. 16, the forklift vehicle 60 is shown by an alternate long and short dash line.

Then, by the time the take-up shaft 4 mounted on the attachment base 40 is lifted to a position lower than the height position of the two brackets 3, the forklift vehicle 60 is omitted in FIG. As shown in FIG. 17 which is a side view and FIG. 18 which is a rear view of FIG. 16, the third mounting member 57 is provided by the wires 51 provided on the attachment base 40 on the left and right sides. The take-up shaft 4 mounted on the above can be suspended and supported. In the present embodiment, the suspension support is provided by winding the lower part of each wire 51 extending downward from the pulley 47 on the front side among the pulleys 47 and 48 provided on the attachment base 40 in the front and rear. This is done by turning the hook member 52 downward and locking the hook member 52 attached to the lower end of the wire 51 to the wire 51 on the upper side of the take-up shaft 4. In such work, the take-up shaft 4 is received from the first mounting member 31 of the transport carriage 20 to the third mounting member 57 of the attachment base 40 by raising the fork 61 of the forklift vehicle 60 from the state of FIG. Immediately after being handed over, it can be done by stopping the ascent of the fork 61, which allows the operator to perform this work at a low position without using a lift such as a ladder or a stepladder.

Next, the operator operates the transmitter described above to drive the drive device 55 provided for each wire 51 to rotate the take-up reel 54 provided for each wire 51 in the forward direction. By winding the wire 51 with these take-up reels 54, the take-up shaft 4 is lifted and supported by the wire 51 from the third mounting member 57. Then, as shown in FIGS. 19 to 21, two height positions of the lift support of the take-up shaft 4 are set on the skeleton 8 which is an immovable member of the building to receive the take-up shaft 4. After the bracket 3 is provided at the same height position or substantially the same height position, the forward rotation of each take-up reel 54 is stopped by operating the transmitter. After that, the forklift vehicle 60 is advanced, or the winding shaft 4 suspended and supported by the wire 51 is pushed by an operator to be provided at both ends of the winding shaft 4 in the axial direction. The neck portion 4A of the head portion 4A is inserted into the recess 3A formed in each bracket 3, whereby both ends of the take-up shaft 4 in the axial direction are inserted into the skeleton 8 with an axial spacing of the take-up shaft 4. It is received by the brackets 3 arranged in two pieces.

Next, the bearing member 12 arranged on each neck portion 4A is fixed to each bracket 3 with a screw or the like, whereby the take-up shaft 4 is rotatably supported by the two brackets 3. ..

In order to rotatably support the take-up shaft 4 by the two brackets 3, the neck portions 4A provided at both ends of the take-up shaft 4 in the axial direction are provided with the recesses of the two brackets 3. It is required to be inserted accurately into 3A, and therefore, the lifting support of the take-up shaft 4 by the wire 51 is such that the height position of each neck portion 4A coincides with or omits the height position of the recess 3A of each bracket 3. It is necessary to do until they match. Therefore, in the present embodiment, of the three wires 51, the two wires 51 arranged on both the left and right sides lift and support two places separated in the axial direction of the take-up shaft 4. The wires 51 can be individually moved up and down by the operator individually rotating the take-up reels 54 in the forward and reverse directions by operating the transmitter described above. By individually raising and lowering the two necks 4A of the take-up shaft 4, even if the take-up shaft 4 is curved downward due to its own weight or the like, the height position of each of the take-up shafts 4A can be changed. It can be exactly or substantially matched with the height position of the recess 3A of each bracket 3.

In the above description, the hoisting support of the take-up shaft 4 is performed by the wires 51 provided on the attachment base 40 in the left-right direction, but the lifting support is performed only by the two wires 51 on the left and right sides. You may go.

In the present embodiment described above, the take-up shaft 4 delivered from the first mounting member 31 of the transport carriage 20 to the third mounting member 57 of the attachment base 40 is arranged with two brackets 3. The work of lifting to a high place in the building is the first lifting to lift the take-up shaft 4 mounted on the attachment base 40 to a place lower than the place where the bracket 3 is arranged by raising the fork 61 of the forklift vehicle 60. It includes a work step and a second lifting work step for lifting the take-up shaft 4 to the place where the bracket 3 is arranged by the wire 51 arranged on the attachment table 40 after that.

Further, in the present embodiment, the above-mentioned first lifting work step is performed by raising the fork 61 of the forklift vehicle 60 in which the attachment table 40 is set. Therefore, the fork 61 carries out the first lifting work step. The wire 51 arranged on the attachment base 40 suspends the take-up shaft 4 to a height where the two brackets 3 are arranged, and lifts and supports the winding shaft 4. Therefore, the wire 51 is provided on the attachment base 40 by a take-up reel 54 for winding and unwinding the wire 51, a drive device 55 for rotating the take-up reel 54 in the forward and reverse directions, and the like. A second lifting means for carrying out the second lifting work process is configured. The wire 51 constitutes a part of the second lifting means, and is a support member for lifting and supporting the take-up shaft 4, and is also a string-shaped member.

In the above embodiment, since the above-mentioned first lifting work step is the work of raising the fork 61 of the forklift vehicle 60, the second lifting work step carried out by winding the wire 51 with the take-up reel 54. Although the work is less accurate than the second lifting work process, it is a work that can be carried out at a higher speed than the second lifting work process. Further, the second lifting work process is a work performed at a lower speed than the first lifting work process, but is more accurate than the first lifting work process due to the control of the vertical movement amount of the wire 51 by the take-up reel 54. It is a work that can be carried out at. Therefore, according to the present embodiment, the lifting work of the take-up shaft 4 whose arrangement location is a high place of the structure can be performed quickly and with high accuracy, and this work can be facilitated.

Further, in the present embodiment, the wire 51 arranged as the support member or the string-like member described above on the attachment base 40 supports at least two places separated in the axial direction of the take-up shaft 4. Since these wires 51 can be raised and lowered individually, the take-up shafts can be raised and lowered individually at two locations separated in the axial direction of the take-up shaft 4 as described above. Even if 4 is curved and deformed downward due to its own weight or the like, the height positions of the neck portions 4A provided at both ends of the take-up shaft 4 in the axial direction can be individually adjusted, whereby these neck portions can be adjusted. The work of matching or substantially matching the height position of 4A with the height position of the recess 3A of each bracket 3 can be performed more accurately and easily.

Next, the work for connecting the upper end of the shutter curtain 1 to the take-up shaft 4 received by the two brackets 3 as described above will be described.

FIG. 22 shows the first work performed to transfer the shutter curtain 1 from the second mounting member 32 of the transport carriage 20 to the fourth mounting member 58 of the attachment base 40 in order to perform this work. There is. In this work, the tubular member 44 of the attachment base 40 set on the fork 61 of the forklift vehicle 60 is mounted on the second mounting member 32 of the transport carriage 20 in the same manner as in the case of the take-up shaft 4 shown in FIG. It is a work of inserting into the lower side of the shutter curtain 1 which is spirally wound and placed, and this insertion work is performed by the position of the pair of second mounting members 32 provided on the transport carriage 20 and the attachment. This is performed until the positions of the pair of fourth mounting members 58 provided on the table 40 match.

At this time, as described above, since the dimension H1 in FIG. 7 is smaller than the dimension H3 in FIG. 4, the lower end portion 1D of the shutter curtain 1 mounted on the second mounting member 32 of the transport carriage 20 is below. Therefore, the above-mentioned insertion work can be performed by intruding the tubular member 44 of the attachment base 40 on the upper side of the connecting member 24 connecting the two base members 21 of the transport carriage 20.

Next, as shown in FIG. 23, by raising the fork 61 of the forklift vehicle 60, the attachment table 40 is lifted by the fork 61, and thereby mounted on the second mounting member 32 of the transport vehicle 20. Work is performed to deliver the shutter curtain 1 that has been used to the fourth mounting member 58 of the attachment table 40. After that, the forklift vehicle 60 is driven to the installation site of the shutter device, and the fork 61 is raised, whereby, as can be seen from FIG. 24, the forklift vehicle 60 is spirally wound around the fourth mounting member 58 of the attachment table 40. The attachment base 40 is raised to a position where the height position of the shutter curtain 1 mounted therein is lower than the height position of the take-up shaft 4 received by the two brackets 3.

Next, the operator hooks the hook member 52 provided at the tip of the wire 51 to the upper end of the shutter curtain 1. As can be seen from FIG. 25, in this hooking operation, the hook member 52 is inserted into the hole 68 of the hanging member 1B provided at the upper end of the shutter curtain 1 in order to connect the upper end of the shutter curtain 1 to the take-up shaft 4. The hole 68 is a bolt hole for inserting a bolt for connecting the hanging member 1B of the shutter curtain 1 to the take-up shaft 4. A plurality of hanging member 1Bs are provided in the left-right direction, which is the axial direction of the shutter curtain 1 wound in a spiral shape, and each hanging member 1B has a height at the hanging member 1B. A plurality of holes 68 having different positions are formed apart from each other in the left-right direction. As a result, when the shutter curtain 1 is wound up by the take-up shaft 4, a hole 68 that can be taken up by the take-up shaft 4 without lateral displacement of the shutter curtain 1 is selected, a bolt is inserted, and a hanging member is inserted. 1B can be coupled to the take-up shaft 4.

In the present embodiment, of the plurality of hanging member 1Bs of FIG. 25 provided in the left-right direction, three are provided in the attachment table 40 in the left-right direction in the holes 68 of the hanging member 1B in the central portion in the left-right direction. Of the wires 51, the hook member 52 of the wire 51 in the central portion in the left-right direction is inserted, and the hook member 52 is formed in a plurality of holes 68 in the hanging source member 1B in the central portion in the left-right direction in the left-right direction. Of these, it is inserted into the hole 68 at the center in the left-right direction. As a result, as will be described later, when the upper end of the shutter curtain 1 is pulled up by pulling up one wire 51 in the central portion in the left-right direction, the entire upper end can be pulled up uniformly.

After performing the above work, the operator operates the transmitter described above to make only one wire 51 in the center of the left-right direction out of the three wires 51 provided in the left-right direction. The take-up reel 54 arranged on the attachment base 40 for 51 is taken up by rotating the take-up reel 54 in a forward direction by the drive device 55, whereby, as shown in FIGS. 24 and 25, with the above-mentioned support member. The upper end of the shutter curtain 1 is pulled up by this wire 51, and the height position of the upper end is set to the same or substantially the same height position as the height position of the take-up shaft 4 supported by the two brackets 3. do. Next, the operator pulls out the hook member 52 from the hole 68 and connects each hanging member 1B to the take-up shaft 4 by the above-mentioned bolt as shown in FIG. 26.

Next, the operator rotates the take-up shaft 4 rotatably supported by the two brackets 3 in a positive direction, so that the shutter is spirally wound around the fourth mounting member 58 of the attachment table 40. From the curtain 1, each slat 1C serially connected to form the shutter curtain 1 is unwound and wound by the take-up shaft 4. The state when this work is performed is shown in FIG. 27. At this time, the shutter curtain 1 wound in a spiral shape rotates on the fourth mounting member 58, and the fourth mounting member 58 is a rotatable rotating member as described above. Therefore, the shutter curtain 1 can be smoothly rotated on the fourth mounting member 58, whereby the work of winding each slat 1C on the take-up shaft 4 can be performed more reliably.

If by this time, the work of attaching the switch 5 and the driving force transmission device 6 shown in FIG. 1 for rotating the take-up shaft 4 to one of the two brackets 3 has been completed. The work of rotating the take-up shaft 4 in the forward direction in order to take up each slat 1C of the shutter curtain by the take-up shaft 4 may be performed by using these switches 5 and the driving force transmission device 6.

After the work of winding the entire shutter curtain 1 on the take-up shaft 4 is completed, the work of attaching the left and right guide rails 2 shown in FIG. 1 to the skeleton 7, the work of attaching the shutter case 9 to the skeleton, and the like are leftovers. Do the work. Next, the take-up shaft 4 is rotated in the reverse direction by a switch 5, a driving force transmission device 6, or the like, whereby both ends of the shutter curtain 1 unwound from the take-up shaft 4 in the width direction are inside the left and right guide rails 2. The shutter curtain 1 is lowered by inserting it in a slidable manner. When this work is completed, the shutter device is in a state where the doorway 10 of FIG. 1 can be opened and closed by the shutter curtain 1.

In the above embodiment, the wire 51 at the center in the left-right direction is a string-shaped member suspended from above the shutter curtain 1 mounted on the fourth mounting member 58 of the attachment table 40, and is a shutter. It also serves as a pulling member for pulling up the upper end of the curtain 1. The attachment base 40 on which the wire 51, which is a pulling member, is arranged in this way also serves as a pulling device.

According to the present embodiment described above, the shutter curtain 1 whose upper end is coupled to the take-up shaft 4 rotatably received by the two brackets 3 opens and closes the entire entrance / exit 10 or substantially the entire doorway 10 in advance at the factory. Since the shutter curtain 1 is formed to a size that can be used, the shutter curtain 1 having such a size is installed after the suspension member 1B is connected to the take-up shaft 4 with a bolt at the installation site of the shutter device. The work for winding up can be carried out by the take-up shaft 4. Therefore, at the installation site of the shutter device, after the suspension member 1B is bolted to the take-up shaft 4, each slat 1C forming most of the shutter curtain 1 is attached to the upper and lower ends of these slat 1C. In order to form the shutter curtain 1 by rotatably engaging the curled portions formed with each other, it is possible to omit the sliding work for sequentially inserting these slats 1C from the lateral direction. The work of forming the shutter curtain 1 to be wound around the winding shaft 4 can be easily performed.

Further, according to the present embodiment, the tip of the wire 51, which is the above-mentioned string-shaped member and the pulling member, is inserted into the hole 68 of the hanging member 1B provided at the upper end of the shutter curtain 1. Since the hook member 52 for hooking and pulling up the upper end of the shutter curtain 1 is provided, the work of pulling up the upper end of the shutter curtain 1 in order to connect the upper end to the take-up shaft 4 is performed on the take-up shaft 4. This can be done by using the hanging member 1B provided at the upper end of the curtain 1 in order to connect the upper ends. Further, since the hole 68 for hooking the hook member 52 is a bolt hole for inserting a bolt that connects the hanging member 1B to the take-up shaft 4, the shutter curtain 1 is pulled up by the wire 51 using this bolt hole. You can do the work.

Further, in the present embodiment, the shutter curtain 1 mounted on the fourth mounting member 58 of the attachment table 40 is described above before the work of pulling up the upper end of the shutter curtain 1 by the hook member 52 of the wire 51 is performed. The fork 61 of the forklift vehicle 60, which is a lift device, lifts the fork 61 to a position slightly lower than the height position of the take-up shaft 4 received by the two brackets 3, and therefore the lift device. The wire 51, which is a pulling member of the attachment base 40, allows the work of pulling the upper end of the shutter curtain 1 to the same or substantially the same height position as the winding shaft 4 in a short time. The work can be performed, and as a result, the entire work time until the upper end of the shutter curtain 1 is connected to the take-up shaft 4 can be shortened.

In the embodiment described above, the upper end of the shutter curtain 1 is connected to the take-up shaft 4 by one wire 51 in the central portion in the left-right direction among the three wires 51 provided in the attachment table 40 in the left-right direction. Therefore, the work of pulling up the upper end is performed, but the work of pulling up the upper end of the shutter curtain 1 may be carried out by using three wires 51.

Further, among the shutter curtains 1, the seat plate 1A of FIG. 1 forming the lower end of the shutter curtain 1 has both left and right ends of the seat plate 1A not inserted into the left and right guide rails 2. Therefore, it is assumed that the shutter curtain 1 formed in the factory in advance excludes the seat plate 1A, and as described above, the shutter curtain 1 unwound from the take-up shaft 4 due to the reverse rotation of the take-up shaft 4. Both ends in the width direction may be slidably inserted into the left and right guide rails 2, and after the shutter curtain 1 is lowered, the work of connecting the seat plate 1A to the lower end of the shutter curtain 1 may be performed. ..

According to this, unlike the slats 1C, the seat plate 1A is a member of the shutter curtain 1 having a large thickness dimension of the shutter curtain 1, so that the seat plate 1A is mounted on the second mounting member 32 of the transport carriage 20. In addition, when the shutter curtain 1 is wound in a spiral shape, this winding operation can be easily performed by reducing the diameter of the shutter curtain 1.

The hook member 52 of the wire 51 can be hooked to the upper end of the shutter curtain 1, for example, by providing a hole in the uppermost slat 1C among a large number of slat 1Cs serially provided to form the shutter curtain 1. It may be done by hooking it on a locking portion such as a protrusion. However, as described above, the above-mentioned effect can be obtained by hooking the hook member 52 into the hole 68 formed as a bolt hole in the suspension member 1B provided at the upper end of the shutter curtain 1.

Further, in FIGS. 26 and 27, the shutter curtain 1 pulled up by the hook member 52 of the wire 51 and having the upper end connected to the take-up shaft 4 rotates clockwise in the fourth mounting member 58 of the attachment table 40. However, this rotation direction may be reversed.

FIG. 28 shows a shutter curtain in which a building material mounted on a second mounting member 32 of a transport carriage 20 is wound around a take-up shaft 4 and a take-up shaft 4 having an upper end coupled to the take-up shaft 4. The embodiment set to 1 is shown. Therefore, the building material of this embodiment is the coupling 70 of the take-up shaft 4 and the shutter curtain 1. Also in this embodiment, as shown in FIG. 29, by raising the fork 61 of the forklift vehicle 60 after performing the same work as the work of FIG. 22 showing the case of the shutter curtain 1, the coupling is formed. The 70 can be delivered from the second mounting member 32 of the transport trolley 20 to the fourth mounting member 58 of the attachment base 40.

FIG. 30 shows a state in which the coupling 70 is suspended and supported by each of the three wires 51 provided on the attachment table 40, as in the case of the take-up shaft 4 of FIGS. 18 and 21. .. Also in this embodiment, as in the case of the take-up shaft 4, it is necessary to carry out the work of accurately receiving the neck portions 4A provided at both ends of the take-up shaft 4 in the axial direction with the two brackets 3. Therefore, of the three wires 51, the operator operates the transmitter described above with the two wires 51 supporting the two wires 51 on the left and right sides of the coupling 70 separated from each other in the axial direction. By individually rotating the take-up reels 54 for these wires 51 in the forward and reverse directions, the reels 54 are raised and lowered individually, whereby the two neck portions 4A of the take-up shaft 4 are individually raised and lowered. , The height position of each neck portion 4A can be more accurately matched or substantially matched with the height position of the recess 3A of each bracket 3.

Even in the coupling 70 of the winding shaft 4 and the shutter curtain 1 according to this embodiment, in order to lift the coupling 70, the coupling 70 is suspended and supported among the three wires 51. It may be performed using only two wires 51 on both the left and right sides.

FIG. 31 shows another embodiment of suspending and supporting the coupling 70 of the take-up shaft 4 and the shutter curtain 1 so as to be lifted by the wire 51. Also in this embodiment, of the two front and rear pulleys 47 and 48 provided on the attachment table 40, the lower portion of the wire 51 extending downward from the front pulley 47 is mounted on the fourth mounting member 58. The hook member 52 attached to the lower end of the wire 51, which is turned to the lower side of the coupling 70, is attached to the holding member 49'that rotatably holds the two pulleys 47 and 48 on the front side. It is locked to a locking member 71 provided in front of the pulley 47 by a pin or the like.

Also in this embodiment, the coupling 70 can be suspended and supported by the wire 51, and the coupling 70 can be lifted by the wire 51 by the forward rotation of the winding reel 54 for winding and unwinding the wire 51.
