  In FIG. 48, a support column 210 is integrally erected on the left and right sides facing the frontage 200, and left and right guide rails 230 disposed opposite to each other are fixed to the left and right support columns 210. The left and right guide rails 230 are formed to have a vertical rail portion 240 and a horizontal rail portion 250 protruding substantially horizontally rearward and upward from an upper end portion of the frontage 200 at an upper end portion of the vertical rail portion 240. I have. An overdoor curtain 260 is disposed between the left and right guide rails 230, and a plurality of engaging pins (not shown) provided at upper and lower ends of both ends of the overdoor curtain 260 are respectively engaged with the left and right guide rails 230 so as to be able to move up and down. The over-door curtain 260 is opened and closed along the left and right guide rails 230 via the engagement pins at the upper and lower portions of both ends.

  The over-door curtain 260 is configured such that a large number of door panels 270 that are long in the left-right direction are overlapped in the up-down direction, and are rotatably connected to each other by hinges (not shown). A bracket 280 is attached to the upper ends of the left and right columns 210, and a rotating shaft 290 is rotatably mounted between the left and right brackets 280, and the winding drum 300 is fixed to both ends of the rotating shaft 290. A wire 310 having a winding end fixed thereto is wound around the left and right winding drums 300, and the left and right wires 310 unwound from the left and right winding drums 300 are wound at the unwinding ends. Left and right ends of the door panel 270 located at the lowermost end of the overdoor curtain 260 are fixedly supported.

  A spring 320 is mounted on the rotating shaft 290 so as to urge the left and right winding drums 300 in a direction in which the wire 310 is wound. The left and right winding drums 300 rotate in the winding direction and the rewinding direction, so that the overdoor curtain 260 moves up and down via the left and right wires 310 to open and close the frontage 200.

  The overdoor device 350 operates as follows.

  As described above, in the general overdoor device 350, the left and right winding drums 300 rotate toward the direction in which the left and right wires 310, 310 are wound by the springs 320, 320, or, conversely, the left and right The torso 300 rotates in the direction in which the left and right wires 310 are rewound. Due to the rotation of the left and right winding drums 300, the springs 320, 320 are bent along the cross-sectional direction of the rotating shaft 290 in the longitudinal gap between the rotating shaft 290 and the springs 320, 320 (oscillation). Do). That is, the springs 320, 320 bend (swing) in the direction in contact with the rotating shaft 290.

  Therefore, the oscillating springs 320, 320 can easily approach the rotation shaft 290 via a gap between the rotation shaft 290 and the springs 320, 320. As a result, the possibility that the springs 320 and 320 come into contact with the rotating shaft 290 increases. Then, when the springs 320, 320 make contact with the rotating shaft 290 by swinging, the rotating shaft 290 generally does not easily absorb the contact (contact by collision) due to the swing by the springs 320, 320. In particular, when the rotation shaft 290 and the spring 230 are made of a hard material such as a metal material, there is a tendency that it is difficult to absorb the contact due to the swing (the contact due to the collision). Therefore, there is a possibility that a contact sound may be generated due to a contact (a contact due to a collision) of the rotation of the springs 320 with the rotation shaft 290.

  In the above, the guide rail 4, the panel body 6 and the lowermost panel body 7 constituting the shutter curtain 5 have been described. Next, the plurality of panel bodies 6 on the guide rails 4, 4 and the lowermost section A method of assembling the shutter curtain 5 by incorporating the panel body 7 will be described. First, in this example, in order to incorporate the roller 16 into the end (the end in the closed position 3 direction side) of the panel body 7 at the lowermost end, the vertical rails 18 and 18 are opened from the end in the open position 2 direction (FIG. 14, the tire portions 16a of the rollers 16, 16 are inserted into the hollow portions 18b, 18b. The tires 16a, 16a of the rollers 16, 16 are moved in the hollow portions 18b, 18b in the direction of the arrow β shown in FIG. Section). Then, the panel member 7 at the lowermost end, which is the lowermost end of the shutter curtain 5, is incorporated between the vertical rails 18 standing on both sides of the opening 10 of the box-type carrier.

  Specifically, as shown in FIG. 15, the lowermost panel body 7 is placed on the closed position 3 between the vertical rails 18, 18, and the lowermost panel body 7 is sandwiched between the vertical rails 18, 18. To do. At this time, the shaft portions 16b, 16b of the rollers 16, 16 already in the vertical rails 18, 18 are incorporated into the semicircular recess 30 extending in the width direction of the lowermost panel body 7 (see FIG. 15). . However, in this state, the lowermost panel body 7 is merely sandwiched and placed on the closed position 3 between the vertical rails 18, 18. The panel body 7 is in a state where it can easily fall in the direction of the arrow γ shown in FIG. 15 (inside or outside the box-type carrier). In particular, since the sealing member 31 such as a drainer seal made of an elastic member is inserted into the end face portion 7c facing the closed position of the panel member 7 at the lowermost end, the panel member 7 at the lowermost end tends to fall down. It has become. Then, the panel body 7 at the lowermost end is supported so as not to fall down by using the panel body assembling jig 50 which is a temporary fixing member.

  As shown in FIG. 16, the panel body assembling jig 50 is basically made of two flat members 51 and 52, and includes a holding portion 50a and a holding portion 50b. The holding portion 50a has a substantially U-shape as shown in FIG. The substantially U-shaped shape is formed by making a flat plate portion 51a of one flat plate member 51 face a flat plate portion 52c of another flat plate member 52. That is, a plurality of portions near the end of the other flat plate member 52 are bent at substantially right angles (bending positions 52e and 52f) to form the flat plate portion 52c, and this substantially U-shaped shape is created. . A hole 52b in which a female screw is formed is provided at an end of the flat plate 52c. A push screw 52a composed of a butterfly head and a bolt is screwed into the female screw.

  Further, a holding portion 50b is provided extending from the holding portion 50a having a substantially U-shape. The holding portion 50b includes a flat plate portion 51b and a flat plate portion 52d of two flat plate members 51 and 52. That is, the holding portion 50b is formed by overlapping the flat plate portion 51b and the flat plate portion 52d by means such as bonding. The above is the panel body assembling jig 50 used in this example. However, the present invention is not particularly limited to this configuration. It is also possible. Also, when forming a substantially U-shaped shape, it is not always necessary to bend the bending position at a substantially right angle, and the bending angle at the bending position is arbitrary as long as the flat plate portion 51a and the flat plate portion 52c can be formed to face each other. It is also possible.

  The panel body assembling jig 50 holds the vertical rail 18 so as to support the panel body 7 at the lowermost end. At this time, the panel body assembling jig 50 is mounted so as to support a position that does not hinder the mounting of the roller receiving member 27, for example, a substantially center position of the panel body 7 at the lowermost end. In this example, as shown in FIG. 17, the panel body assembling jig 50 is attached to the center position of the panel body 7 at the lowermost end. Then, as a method of using the panel body assembling jig 50, first, the panel body assembling jig 50 is inserted into the gap s formed between the vertical rail 18 and the panel body 7 at the lowermost end. The end 51a of the member 51 is inserted (see FIGS. 18 and 19).

  As shown in FIG. 18, the gap s between the vertical rail 18 and the lowermost panel body 7 is such that the thickness t of the panel body 7 of the lowermost panel body 7 from the insertion opening 18 a of the vertical rail 18. This is the gap s caused by being thin. As shown in FIG. 19, the flat plate portion 51a of the flat plate member 51 is inserted into the gap s, and the flat plate portion 51a is moved toward the hollow portion 18b in a state of approaching (or in contact with) the end 18c of the vertical rail 18. Let me enter. With the entry, the flat plate portion 52c of the flat plate member 52 facing the flat plate portion 51a of the substantially U-shaped flat plate member 51 comes into contact with the outer surface 18d of the vertical rail 18. Then, the end of the flat plate portion 51a of the flat plate member 51 is inserted into the hollow portion 18b of the vertical rail 18 so as to come into contact with the inner surface 18e of the vertical rail 18 (see FIG. 19).

  When the relationship between the vertical rail 18 and the holding portion 50a of the panel body assembling jig 50 is as shown in FIG. 19, the butterfly-shaped head of the push screw 52a screwed into the hole 52b is rotated. . Then, the butterfly-shaped head of the push screw 52a is rotated so that the tip of the bolt of the push screw 50a presses the outer surface 18d of the vertical rail 18 from the hole 52b. When the tip of the bolt of the push screw 52a comes into contact with the outer surface 18d of the vertical rail 18 while applying pressure, the jig 50 for assembling the panel body sandwiches the vertical rail 18 and is fixed as shown in FIG. . As a result, the holding portion 50b of the panel body assembling jig 50 supports the panel body 7 at the lowermost end. In other words, when the holding portion 50a of the panel body assembling jig 50 is fixed to the vertical rail 18, the direction of the end of the holding portion 50b of the panel body assembling jig 50 (the direction of the folded portion 52g) is the lowermost panel. This makes it easier to come into contact with the back surface 7b of the body 7, supports the lowermost panel body 7, and makes it difficult to fall down. This means that the lowermost panel body 7 is in a state in which the lowermost panel body 7 is temporarily fixed from the state in which the lowermost panel body 7 easily falls down in the arrow γ direction (inside or outside the box-type carrier) shown in FIG. (See FIG. 17).

  In the state where the lowermost panel body 7 is supported by the panel body assembling jig 50 in this manner, as shown in FIGS. 17 and 20, a semicircular arc on the back surface 7b side of the lowermost panel body 7 is formed. The shaft portion 16b of the roller 16 incorporated in the concave portion 30 is covered with a roller receiving member 27 (a flat plate portion 27a), the bolts 13 are passed through the bolt holes 32, 32, and the nuts 14 are screwed and fixed. Similarly, the shaft portion 16b of the roller 16 on the side of the vertical rail 18 (not shown) is covered and fixed by the roller receiving member 27 (the flat plate portion 27a). Thus, as shown in FIG. 20, assembly of the lowermost panel body 7 to the vertical rails 18 is completed. Next, the tire portions 16a, 16a of the rollers 16, 16 are inserted into the hollow portions 18b, 18b from the ends of the vertical rails 18, 18 in the two open positions. Then, as shown in FIG. 21, the tire portions 16a, 16a of the rollers 16, 16 are moved in the hollow portions 18b, 18b to move the tire portions 16a, 16a in the first connecting portion 8 of the lowermost panel body 7 (first opening portion). 8a), the shafts 16b, 16b of the rollers 16, 16 are placed in the first connecting portion 8 (in the first opening 8a).

  The panel body 6 is mounted on the shaft portions 16b of the rollers 16, 16 as shown in FIG. By mounting the panel body 6, the shaft portions 16b, 16b of the rollers 16, 16 are connected to the first connecting portion 8 (first opening portion 8a) of the panel body 7 at the lowermost end and the second connecting portion (first opening portion) of the panel body 6. It is surrounded by a fitting portion with the two openings 9a). In this state, the panel body 6 is simply sandwiched between the vertical rails 18 and 18 and placed on the panel body 7 at the lowermost end. Since there is no support for the panel body 6, the panel body 6 It is in a state where it easily falls down in the arrow γ direction (inside or outside of the box-type carrier) shown in FIG. For this purpose, the panel body assembling jig 50 is mounted so as to support the center position of the panel body 6 similar to the lowermost panel body 7 without hindering the mounting of the roller receiving member 21. As shown in FIG. 23, the panel body 6 is temporarily fixed by attaching the panel body assembling jig 50.

  In the state where the panel body 6 is supported (temporarily fixed) by the panel body assembling jig 50 in this manner, as shown in FIG. The shaft portion 16b of the roller 16 surrounded by the fitting portion between the one connecting portion 8 (first opening portion 8a) and the second connecting portion (second opening portion 9a) of the panel body 6 is transferred to the roller receiving member 21 (flat plate portion). 21a), and the bolts 11, 11 are passed through the bolt holes 22, 22, and screwed and fixed to the nuts 14, 14. Similarly, the shaft portion 16b of the roller 16 on the side of the vertical rail 18 (not shown) is covered and fixed by the roller receiving member 21 (the flat plate portion 21a). As described above, the assembly of the panel body 6 on the panel body 7 at the lowermost end to the vertical rails 18 is completed (see FIG. 23).

  In this way, the tire portions 16a, 16a of the rollers 16, 16 are inserted into the ends of the vertical rails 18, 18 in the two open positions, and are moved to the first connecting portion 8 (first opening portion 8a) of the panel body 6, The panel body 6 is placed so as to sandwich the shaft portions 16b of the rollers 16,16. As a result, the first connecting portions 8 (first opening portions 8a) and the second connecting portions (second opening portions 9a) of the panel bodies 6, 6 that are adjacent to the shaft portions 16b, 16b of the rollers 16, 16 are adjacent to each other. It will be surrounded by the fitting part. Then, the panel body 6 on which the panel body 6 is placed is temporarily fixed by the panel body assembling jig 50, and the shaft portions 16 b, 16 b of the rollers 16, 16 are repeatedly covered by the roller receiving members 21, 21. By repeating this, the shutter curtain 5 is assembled by incorporating the plurality of panel bodies 6 to the guide rails 4 and the panel body 7 at the lowermost end.

  In the present embodiment, the roller 16 is inserted into the vertical rail 18 and means for covering the shaft portion 16b of the roller 16 with the panel members 6, 7 supported by the panel assembly jig 50 is used. As shown in FIG. 7, since there is a gap w other than the gap s between the panel body 7 at the lowermost end and the vertical rail 18, both width directions of the panel bodies 6, 7 supported by the panel body assembly jig 50 are provided. It is also possible to insert the roller 16 using these gaps s and w. Further, in this example, the panel body assembling jig 50 is attached to only one of the vertical rails 18, but the panel body assembling jigs 50, 50 are used for the vertical rails 18, 18 on both sides. It is also possible to support the panel body 6 and the panel body 7 at the lowermost end.

  Then, the tire portions 16a, 16a, which are the heads of the rollers 16, 16 projecting from both side edges of the shutter curtain 5 in which the plurality of panel bodies 6 are assembled, move in the guide rails 4, 4. Specifically, as shown in FIG. 24, the tire portions 16 a of the rollers 16 projecting from both side edges of the shutter curtain 5 are provided inside the guide rails 4, 4 erected on both side edges of the shutter curtain 5. Will roll. FIG. 24 shows the tire portions 16a, 16a rolling inside the vertical rails 18, 18 as the guide rails 4, 4, but the tire portions 16a, 16a are the guide rails 4, 4, not shown in FIG. The connection rails 20, 20 and the horizontal rails 19, 19 also roll in the same manner. The pair of vertical rails 18, connecting rails 20, and horizontal rails 19 have hollows that are continuous with the insertion openings 18a, 20a, 19a that are open so that the tire portions 16a, 16a of the rollers 16, 16 can move. Parts 18b, 19b and 20b are provided. Specifically, as shown in FIG. 25, the end surfaces of the pair of vertical rails 18, the connecting rails 20, and the horizontal rails 19 are bent to form hollows in the pair of vertical rails 18, the connecting rails 20, and the horizontal rails 19. Parts 18b, 20b, and 19b are provided. The tire portion 16a of the roller 16 can pass through the hollow portions 18b, 20b, and 19b.

  The hook-shaped members 25, 25 provided in the small holes 24, 24 penetrating through the thickness t direction of the panel body 7 at the lowermost end of the shutter curtain 5 assembled as described above have string-like members 35, 35. Are attached (connected). In the present embodiment, the wire 35 is used as the string-like member 35 attached to the hook-like member 25 for moving a large number of rollers 16 in both width directions (side edges) of the shutter curtain 5. However, the string-shaped member 35 is not limited to the wire 35, and a chain, a belt, or the like can be used. Then, these chains, belts, and the like are attached to the hook-shaped member 25, and are wound or unwound by using a drum 37 or the like, so that a large number of rollers 16 in both width directions (side edges) of the shutter curtain 5 are provided. It is possible to move.

  Then, the ends of the wires 35, 35 are hooked (attached) to the hook portions 26, 26 of the hook-shaped members 25, 25. How to attach the ends of the wires 35 to the hook portions 26 of the hook-shaped members 25 will be described with reference to FIGS. As shown in FIG. 26, resin-made ring-shaped members 36, 36 are incorporated at ends of the wires 35, 35 so as to surround the resin-made ring-shaped members 36, 36 by the wires 35, 35. . One ends of the wires 35 surrounding the resin-made ring members 36 are fixed by sleeves 34.

  By passing the hook-shaped members 25, 25 through the center holes of the resin-made ring-shaped members 36, 36 in the ends of the wires 35, 35 into which the resin-made ring-shaped members 36, 36 are incorporated, the resin-made The ends of the wires 35, 35 incorporating the ring members 36, 36 are hooked on the hook portions 26, 26 of the hook members 25, 25 (see FIG. 13). In this way, the ends of the wires 35, 35 incorporating the resin-made ring members 36, 36 are hooked on the hook portions 26, 26, and then the hook-shaped members 25, 25 are attached to the thickness of the panel body 7 at the lowermost end. It is fixed to the small holes 24, 24 penetrating in the t direction. At this time, the hook portions 26, 26 of the hook members 25, 25 project toward the surface 7a of the panel body 7 at the lowermost end (see FIG. 25). However, as shown in FIG. 25, since the members 33, 33 are attached near the opening 10 of the box-type carrier, the hooks 26, 26 are difficult to see from the outside of the opening 10 of the box-type carrier. ing. In this example, the resin ring-shaped members 36, 36 are incorporated into the ends of the wires 35, 35, but the members are not limited to resin members as long as they are slippery.

  Then, as shown in FIGS. 2 and 27, the wires 35, 35 are wound by drums 37, 37 attached to both sides of the rotary shaft 40 near the open position 2 of the opening 10 of the box-type carrier. Or be rewound. Notches (not shown) are provided in the drums 37, 37, and sleeves 38, 38, which are the other ends of the wires 35, 37, are hooked and attached to the notches. Therefore, when removing the wires 35, 35 from the drums 37, 37, the wires 35, 35 wound on the drums 37, 37 are moved together with the drums 37, 37 along the rotation shaft 40 in the direction of arrow H in FIG. By moving (shifting), the drums 37, 37 are removed from the rotation shaft 40, and the wires 35, 35 are removed. The drums 37, 37 are inserted from both ends of the rotating shaft 40, and are fixed and attached by bolts 37a, 37a at both ends of the rotating shaft 40, as shown in FIG. The drums 37, 37 rotate in the rotating direction. As shown in FIG. 27, a spring 42, which is an elastic member for controlling the operation of the shutter curtain 5, is attached to one of the brackets 43 supporting the rotating shaft 40. It is wound adjacently. The rotating shaft 40 is provided with a ring 44 for positioning the spring 42 adjacent to the wound spring 42.

  In the panel shutter 1 of the present invention, the shutter body 5 is opened or closed by manually moving the panel body 7 at the lowermost end of the shutter curtain 5. However, it is also possible to provide a driving device (motor), transmit rotation from the driving device to the rotating shaft 40, and automatically rotate the rotating shaft 40 to open or close the shutter curtain 5. .

  Next, the operation of the panel shutter 1 which is the opening / closing device of the present invention will be described. First, the operation when the shutter curtain 5 moves from the open position 2 to the closed position 3 will be described. First, the shutter curtain 5 has the shutter curtain 5 (the panel body 7 at the lowermost end) in the horizontal rails 19, 19 or in the connecting rails 20, 20, and is hidden by the outer portion 12 of the box-type carrier from outside. The shutter curtain 5 is located at the open position 2 where the (lowest lower end panel body 7) is not seen. In this state, the panel body 7 at the lowermost end of the shutter curtain 5 is manually moved (by gripping the handles 5a, 5a) from the open position 2 to the closed position 3. At this time, the wires 35, 35 connected to the drums 37, 37 from the hook-shaped members 25, 25 attached to the panel body 7 at the lowermost end are pulled, and the drums 37, 37 are moved in the direction of arrow A shown in FIG. Rotate to At this time, a certain tension acts on the wires 35, 35 between the hook-like members 25, 25 of the lowermost panel body 7 to which the wires 35, 35 are attached and the drums 37, 37.

  With the rotation of the drums 37, 37, the rotation shaft 40 on which the drums 37, 37 are attached to both ends also rotates in the same arrow A direction as the drums 37, 37. Then, the wires 35 wound around the drums 37 are rewound. As the wires 35, 35 are rewound, the spring 42 wound around the rotating shaft 40 acts on the own weight of the shutter curtain 5 in the direction of winding the wires 35, 35, as shown in FIG. Then, the shutter curtain 5 starts to move in the direction of closing the opening 10 of the box type carrier (the direction of arrow C). At this time, a large number of rollers 16 attached to both side edges of the shutter curtain 5 also have a shaft portion 16b in the panel body 6 (a connecting portion between the adjacent panel bodies 6, 6) and a tire in the guide rails 4, 4. The part 16a starts moving while rotating.

  Then, (the plurality of panel bodies 6 including the lowermost panel body 7) of the shutter curtain 5 move from the connecting rails 20, 20 to the vertical rails 18, 18. At this time, a large number of rollers 16 attached to both side edges of the shutter curtain 5 also have a shaft portion 16b in the panel body 6 (a connecting portion between the adjacent panel bodies 6, 6) and a tire in the guide rails 4, 4. The part 16a moves from the connecting rails 20, 20 to the vertical rails 18, 18 while rotating. Further, when the lowermost panel body 7 is manually moved in the closing direction, the rotation of the drums 37, 37 in the direction of arrow A continues, the rotation shaft 40 also rotates, and the wires 35, 35 wound on the drums 37, 37 are rotated. Is rewound. As the wires 35, 35 are rewound, the tire portions 16a of the numerous rollers 16 attached to both side edges of the shutter curtain 5 move while rotating in the vertical rails 18, 18, and the lowermost end of the shutter curtain 5 The panel body 7 of the section goes to the closed position 3.

  At this time, by the action of the spring 42 wound around the rotation shaft 40, the shutter curtain 5 further moves while applying tension to the wires 35, 35 between the hook-shaped members 25, 25 and the drums 37, 37. It moves in the direction to close the opening 10 of the box-type carrier. Finally, the panel body 7 at the lowermost end of the shutter curtain 5 reaches the closed position 3 by the rotation of the drums 37, 37 in the direction of arrow A. At this time, the seal member 31 attached to the panel body 7 at the lowermost end of the shutter curtain 5 comes into contact with and reaches the closed position 3 at a speed from the open position 2 to the closed position 3 of the shutter curtain 5. Thus, the shutter curtain 5 closes the opening 10 of the box-type carrier (see FIG. 29).

  Next, the operation when the shutter curtain 5 moves from the current closed position 3 to the open position 2 will be described. As shown in FIG. 29, in a state where the panel body 7 at the lowermost end of the shutter curtain 5 is in the closed position 3, the panel body 7 at the lowermost end of the shutter curtain 5 is manually moved (by gripping the handle parts 5a, 5a). B) move from the closed position 3 to the open position 2; At this time, the wires 35, 35 connected to the drums 37, 37 from the hook-shaped members 25, 25 attached to the panel body 7 at the lowermost end are operated by the spring 42 wound around the rotating shaft 40. While maintaining a constant tension, it is wound around the drums 37, 37, and the drums 37, 37 rotate in the direction of arrow B shown in FIG. Specifically, by moving the panel body 7 at the lowermost end of the shutter curtain 5 to the open position 2, the wires 35, 35 attached to both side edges of the panel body 7 at the lowermost end are connected to the drums 37, 37. The spring 42 wound around the rotating shaft 40 acts so that the wire 35 is wound around the drums 37, 37 (in the direction of arrow B).

  When the wires 35 are wound, the action of the spring 42 wound on the rotating shaft 40 causes the shutter curtain 5 to open the opening 10 of the box-type carrier in the direction of arrow D shown in FIG. Moving. At this time, a large number of rollers 16 attached to both side edges of the shutter curtain 5 also have a shaft portion 16b in the panel body 6 (a connecting portion between the adjacent panel bodies 6, 6) and a tire in the guide rails 4, 4. The part 16a starts moving while rotating. At this time, a certain tension acts on the wires 35, 35 between the hook-like members 25, 25 of the lowermost panel body 7 to which the wires 35, 35 are attached and the drums 37, 37. Then, the panel body 7 at the lowermost end of the shutter curtain 5 moves away from the closed position 3 toward the open position 2 along the vertical rails 18. Further, when the lowermost panel body 7 is manually moved in the opening direction, the rotation of the drums 37, 37 in the direction of arrow B continues, and the rotating shaft 40 also rotates, and the wires 35, 35 wound on the drums 37, 37 are rotated. Is wound up, and a number of rollers 16 attached to both side edges of the shutter curtain 5 move while rotating inside the vertical rails 18, 18, and the panel body 7 at the lowermost end of the shutter curtain 5 is moved to the open position 2. Heading.

  At this time, by the action of the spring 42 wound around the rotation shaft 40, the shutter curtain 5 further moves while applying tension to the wires 35, 35 between the hook-shaped members 25, 25 and the drums 37, 37. It moves in the direction to open the opening 10 of the box-type carrier. At this time, since the action of the spring 42 gradually exceeds the own weight of the shutter curtain 5, it is easy to manually move the lowermost end of the panel body 7 in the opening position 2 direction. Further, as the rotation of the rotating shaft 40 in the direction of arrow B shown in FIG. 28 continues, the wires 35, 35 are wound around the drums 37, 37. By winding the wires 35, 35, a large number of rollers 16 attached to both side edges of the shutter curtain 5 form a shaft portion 16 b in the panel body 6 (the connecting portion between the adjacent panel bodies 6, 6). The tire portion 16a moves while rotating in the guide rails 4 and 4, and moves from the vertical rails 18 and 18 to the horizontal rails 19 and 19 via the connecting rails 20 and 20. Then, the roller 16 attached to the panel body 7 at the lowermost end of the shutter curtain 5 moves while rotating in the vertical rails 18 and 18 by the action of the spring 42 wound around the rotating shaft 5 and further moves to the open position 2. Head to.

  Finally, the rotation of the rotating shaft 40 in the direction of the arrow B causes the wires 35, 35 to move the hook-shaped members 25, 25 (the bottommost panel body 7) in the two open positions, and to release the shutter. The panel body 7 at the lowermost end of the curtain 5 reaches the open position 2. At this time, the shutter curtain 5 moves from the vertical rails 18, 18 to the horizontal rails 19, 19, and the panel body 7 at the lowermost end of the shutter curtain 5 is in the horizontal rails 19, 19 or in the connecting rails 20, 20. The shutter curtain 5 (the lowermost panel body 7) is hidden from the outside by being hidden by the outer portion 12 of the box-type carrier. In this manner, the shutter curtain 5 opens the opening 10 of the box-type carrier.

  As described above, when the shutter curtain 5 repeats the reciprocating movement from the open position 2 to the closed position 3 or from the closed position 3 to the open position 2, not only the wires 35, 35 but also the ends of the wires 35, 35 The tension is repeatedly applied between the resin-made ring-shaped members 36, 36 and the hook-shaped members 25, 25 incorporated therein. In addition, the shaft portions 16b of a large number of rollers 16 attached to the connecting portions (including the connecting portions of the panel bodies 6 and 7) of the adjacent panel bodies 6 and 6 of the shutter curtain 5 form the adjacent panel bodies 6 and 6 ( The inner wall 15a of the cylindrical hole 15 formed by the panel 7) comes into contact with the inner wall 15a (see FIG. 31), and the roller 16 is rotated. Movement is taking place. Further, since the lowermost panel body 7 is manually moved, the roller 16 often comes into contact with the lowermost panel body 7 and the guide rail 4 (the inner wall 4a) in addition to the rotational movement. Become. When the reciprocating motion between the open position 2 and the closed position 3 of the shutter curtain 5 is repeated, the lowermost panel body 7 of the shutter curtain 5 reaches the closed position 3 due to reaching the closed position 3. Contact between the attached (fixed) seal member 31 and the closed position 3 will be repeated. Therefore, it is desirable that the wire 35, the roller 16, and the seal member 31 can be appropriately confirmed.

  In order to check the wire 35 of the panel shutter 1 of the present invention, the roller 16 and the seal member 31 attached to the lowermost panel member 7, it is necessary to stop the lowermost panel member 7. The position at which the panel body 7 at the lowermost end is stopped for confirmation may be any position such as the open position 2 and the closed position 3 of the opening 10 of the box-type carrier, but in this example, the shutter curtain is used. 5 is stopped and confirmed between the open position 2 and the closed position 3 of the opening 10 of the box-type carrier.

  In order to confirm the wire 35 attached to the panel shutter 1, first, the hook-shaped member 25 supporting the end of the wire 35 incorporating the resin-made ring-shaped member 36 is removed. For this purpose, the bolts 23 attached to the lowermost panel body 7 shown in FIG. 12 are removed. One end of the hook-shaped member 25 is incorporated above the substantially U-shaped groove 29 to which the lowermost sealing member 31 of the lowermost panel body 7 on the surface 7a side of the box-type carrier is attached. By removing the bolt 23, the other end of the hook-shaped member 25 screwed and fixed to the bolt 23 in the spacer portion 28 becomes free.

  Then, the hook-shaped member 25 incorporated in the panel body 7 at the lowermost end is pulled out from the surface 7a of the panel body 7 at the lowermost end of the opening 10 of the box-type carrier. Then, the wire 35 hung on the hook 26 is separated from the panel body 7 at the lowermost end. Next, when the wire 35 wound around the drum 37 attached to both ends of the rotary shaft 40 is to be removed from the drum 37, the bolt 37a fixing the drum 37 to the rotary shaft 40 is loosened. As shown in FIG. 27, the whole wound wire 35 is moved (displaced) together with the drum 37 in the outward direction (arrow H direction) of the rotary shaft 40. This movement removes the drum 37 from the rotating shaft 40. Since the end of the wire 35 is merely positioned by a notch (not shown) provided on the end face of the drum 37, the entire wire 35 is moved from the drum 37 to the outside of the rotary shaft 40 (in the direction of arrow H). The whole wound wire 35 comes off the drum 37. Then, the wire 35 incorporating the resin-made ring-shaped member 36 is removed from the hook-shaped member 25, and the state of the wire 35 is confirmed. As described above, not only the confirmation but also the replacement of the wire 35 as a consumable part enables the replacement by partially disassembling the panel shutter 1 without disassembling it. Further, since the entire panel shutter 1 can be partially disassembled without disassembly, not only the confirmation of the wire 35 but also the replacement can be performed by using either one of the wires 35 or both of the wires 35. It becomes possible.

  In order to check the roller 16 and the seal member 31 attached to the panel body 7 at the lowermost end of the shutter curtain 5, the roller receiving members 27, 27 near both side edges of the panel body 7 at the lowermost end are required. Need to be removed. For this purpose, bolts 13 attached to fix the roller receiving members 27, 27 near the both side edges of (the back side 7b) of the panel body 7 at the lowermost end shown in FIG. Remove 13 Specifically, since the bolts 13, 13 fixing the roller receiving members 27, 27 are screwed with nuts 14, 14 provided on the back surface 7 b in the lowermost panel body 7, The bolts 13 are removed by unscrewing. By removing the bolts 13, 13, the roller receiving members 27, 27 are separated from the lowermost panel body 7.

  When the roller receiving members 27, 27 are removed from the lowermost panel body 7, as shown in FIG. 30, the shaft portions 16b, 16b of the rollers 16, 16 are placed in the arcuate concave portion 30 of the lowermost panel body 7. Contains. Therefore, the hollow portions 18b and 18b in the guide rails 4 and 4 (vertical rails 18 and 18) and the gap between the guide rails 4 and 4 (vertical rails 18 and 18) and the panel body 7 at the lowermost end are used. Thus, the tire portions 16a, 16a of the rollers 16, 16 can be taken out from the panel body 7 at the lowermost end, and the state of the tire portions 16a, 16a, the shaft portions 16b, 16b of the rollers 16, 16 can be checked or replaced. Or you can. Also, by removing the roller receiving members 27, 27 from the lowermost panel body 7, a T-shaped portion formed by the front and back surfaces 7a, 7b of the lowermost panel body 7, and the head of the sealing member 31 The pressing portions (reverse L-shaped portions) 27b, 27b of the roller receiving members 27, 27, which have closed the substantially U-shaped grooves 29 into which the 31a has entered, also come off. Therefore, the T-shaped portion 31a of the head of the seal member 31 in the substantially U-shaped groove 29 is moved from either direction of the lowermost side edges of the panel body 7 at the lowermost end. By moving the seal member 31, the seal member 31 can be extracted, and the seal member 31 extracted from the lowermost panel body 7 can be checked or replaced. As described above, even when replacing the rollers 16 and 16 or the seal member 31 as the consumable parts, it is also possible to confirm or replace the panel shutter 1 by partially disassembling the panel shutter 1 without disassembling it. Or make it possible.

  It is also possible to check only one of the rollers 16 attached to the panel body 7 at the lowermost end of the shutter curtain 5. In that case, one of the roller receiving members 27 that needs to be confirmed near the both side edges of the panel body 7 at the lowermost end is removed. For this purpose, the bolts 13, 13 fixed to the roller receiving member 27, which are screwed with the nuts 14, 14 provided on the back surface 7 b in the lowermost panel body 7, are unthreaded, The bolts 13 are removed, and the roller receiving member 27 is separated from the lowermost panel body 7. The roller is removed from the lowermost panel body 7 by using the hollow portion 18b in the guide rail 4 (vertical rail 18) and the gap between the guide rail 4 (vertical rail 18) and the lowermost panel body 7. The 16 tire portions 16a are taken out, and the states of the tire portion 16a and the shaft portion 16b of the roller 16 are checked or replaced.

  In the above, the hook-shaped member 25 and the wire 35 are removed to confirm or replace the wire 35 attached to the panel shutter 1, and then attached to the panel body 7 at the lowermost end of the shutter curtain 5. To confirm or replace the roller 16 and the seal member 31, the roller receiving member 27 was removed, and the roller 16 and the seal member 31 were removed. However, it is not necessary to remove each part in such an order, and after confirming or replacing the roller 16 and the seal member 31 attached to the panel body 7 at the lowermost end of the shutter curtain 5, attach them to the panel shutter 1. It is also possible to confirm or replace the wire 35 provided. Further, only the wire 35 attached to the panel shutter 1 is checked or replaced, or only the roller 16 and the seal member 31 attached to the panel body 7 at the lowermost end of the shutter curtain 5 are checked or replaced. It is also possible.

  Further, a cylindrical hole 15 formed by a first opening 8a, a second opening 9a, which is a connecting portion between the adjacent panel bodies 6, 6 of the shutter curtain 5, and an arc-shaped end 21a of the roller receiving member 21. With regard to the shaft 16b of the roller 16 rotating in the inside and the tire 16a of the roller 16 rotating in the guide rails 4, 4, the tire 16a and the shaft 16b of the roller 16 will be described. May also need to be checked. In that case, it is necessary to remove the roller receiving member 21 at the connection portion between the panel bodies 6 adjacent to the shutter curtain 5 to be checked. For this purpose, the bolts 11, 11 attached to fix the roller receiving member 21 shown in FIGS. 6 and 24 are removed. The bolts 11, 11 fixing the roller receiving member 21 are screwed with nuts 14, 14 provided on the back surface 6b side of one of the panel bodies 6, and the bolts 11, 11 are unfastened. Remove. By removing the bolts 11, 11, the roller receiving member 21 is separated from the connecting portion between the adjacent panel bodies 6, 6.

  Then, as shown in FIG. 31, the shaft portion 16b of the roller 16 is in the fitting portion between the first opening 8a and the second opening 9a, and is inside the guide rails 4, 4 (vertical rails 18, 18). The tire portion 16a of the roller 16 is taken out from the fitting portion between the adjacent panel bodies 6, 6 by utilizing the hollow portion 18b of the above and the gap between the guide rail 4 (vertical rail 18) and the panel body 6. The state of the tire portion 16a and the shaft portion 16b of the roller 16 can be confirmed or replaced. As described above, even when any of the rollers 16 on both side edges of the shutter curtain 5 is confirmed or replaced, it is necessary to confirm or partially disassemble a portion to be replaced or replaced without disassembling the entire panel shutter 1. It is possible to respond by.

(Example 2)
Next, another example 2 of the present invention will be described with reference to the drawings.

  FIG. 32 shows a panel body 61 which is an adjustment panel body for connecting to the panel body 6 on the two directions of the open position of the shutter curtain 5 according to the present invention. The end of the panel body 61 connected to the panel body 6 is provided with a second connecting portion 79 having the same shape as the other panel bodies 6 constituting the shutter curtain 5. As shown in Example 1, the second connecting portion 79 opens obliquely to the front and back surfaces 61a and 61b along the cylinder length direction of the panel body 6 (the direction of arrow E shown in FIG. 32) ( A second opening 79a having an outer diameter C that is smaller than the outer diameter D of the first connecting portion 8 (first opening 8a) of the panel body 6 (notched) is opened, and has a substantially C-shaped cross section. . The second connecting portion 79 is also formed so as to be located within the thickness t (panel thickness t) of the panel body 7 at the lowermost end similarly to the second connecting portion 9 of the panel body 6. . The first opening 8a (outer diameter D) of the panel body 6 is larger than the second opening 79a (outer diameter C) of the panel body 61, and the first opening 8a and the second opening 79a can be freely inserted and removed. It is set so that it can be fitted.

  When the panel body 61 is connected to the shutter curtain 5, the end of the panel body 61, which is the end position of the shutter curtain 5 (the end position in the opening position 2 direction side), can be connected to another panel body 6. Instead of the hinge structure, it has a concave shape (recess 61c). The concave portion 61c is formed by extending the front and back surfaces 61a and 61b of the panel body 61 while maintaining the thickness t (panel thickness t) of the panel body 61 of the panel body 61. The concave portion 61c of the panel body 61 can be connected to auxiliary panel bodies 63 and 65 having an outer surface having a convex shape. As shown in FIG. 33, the outer side surfaces of the auxiliary panel members 63 and 65 are formed in a convex shape (convex portions 63a and 65a). The convex portion 63a and the convex portion 65a on the outer surface of the panel 65 are connected to the concave portion 61c of the panel body 61.

  The connection between the concave portion 61c of the panel body 61 and the convex portion 63a of the auxiliary panel body 63 is made by providing a hole that penetrates the concave portion 61c and the convex portion 63a that are in contact with each other, and is fixed by a fixing member such as a bolt and a nut. . That is, a hole is provided at any position in the width direction (the direction of arrow E shown in FIG. 32) of the bottom surface 61d of the concave portion 61c of the panel body 61, and the auxiliary panel body 63 provided at a position facing the hole is provided. A hole (provided in the direction of arrow E shown in FIG. 33) of the bottom portion 63b of the convex portion 63a is overlapped, and a bolt or the like as a fixing member is inserted and fixed with a nut or the like. Therefore, the auxiliary panel body 63 can be removed from the panel body 61 by removing the bolts and nuts, which are fixing members, and the auxiliary panel body 63 is detachable from the panel body 61. However, without using a fixing member, the panel body 61 and the auxiliary panel body 63 are combined (engaged) with the concave part 61c of the panel body 61 and the convex part 63a of the auxiliary panel body 63 and caulked the concave part 61c. It is also possible to connect. In the above, the connection between the concave portion 61c of the panel body 61 and the convex portion 63a of the auxiliary panel body 63 has been described, but the connection between the concave portion 61c of the panel body 61 and the convex portion 65a of the auxiliary panel body 65 is performed in the same manner. Can be.

  Then, the entire length of the shutter curtain 5 (the length along the moving direction of the shutter curtain 5), specifically, the end position of the shutter curtain 5 (the end position in the opening position 2 direction side) is the box-type carrier. It is higher than the open position 2 of the opening 10 and the locus of the movement of the shutter curtain 5 between the open position 2 and the closed position 3 of the opening 10 of the box-type carrier is lower than the rotating shaft 40 (the winding portion). Will be set. Therefore, the end position of the shutter curtain 5 (the end position in the opening position in two directions) is either the panel body 61 or the auxiliary panel bodies 63 and 65. In particular, in this example, two types of auxiliary panel bodies 63 and 65 are prepared in order to respond to various open positions 2, but it is also possible to further increase the types of auxiliary panel bodies.

  In FIG. 34 showing this example, corresponding to the open position 2 of the opening 10 of the box-type carrier, the end position of the shutter curtain 5 ((open position 2 direction side end position) (the overall length of the shutter curtain 5). 3) shows the panel body 61 and the auxiliary panel bodies 63 and 65 attached to the end positions (end positions in the two open positions) of the shutter curtain 5. First, the opening 10 of the box-type carrier. Corresponding to the open position 2, the end position of the shutter curtain (the end position in the open position 2 direction side) can be a panel body 61 (connection between the panel body 6 and the panel body 61) (FIG. 34 (a)) Specifically, if the open position 2 of the opening 10 of the box-type carrier is the position shown in Fig. 35 (a), the end position of the shutter curtain 5 (the open position 2 direction end). Part position) is a panel It becomes 61.

  Further, if the opening position 2 of the opening 10 of the box-type carrier is higher (if the opening 10 of the box-type carrier is larger), the end position of the shutter curtain 5 (the opening position 2) as shown in FIG. It is also possible to use the auxiliary panel body 63 at the position (the end on the side in the direction). That is, the panel body 6 and the panel body 61 are connected, and the auxiliary panel body 63 is further connected to the panel body 61. Specifically, if the open position 2 of the opening 10 of the box-type carrier is the position shown in FIG. 35B, the end position of the shutter curtain 5 (the end position in the open position 2 direction side) is the auxiliary panel. It becomes body 63. Further, corresponding to the height of the open position 2 of the opening 10 of the box-type carrier (the size of the opening 10 of the box-type carrier), the end position of the shutter curtain 5 (the end position on the side of the open position 2 direction). May be used as the auxiliary panel body 65 (FIG. 34 (c)). That is, the panel body 6 and the panel body 61 are connected, and the panel body 61 is connected to the auxiliary panel body 65 longer than the auxiliary panel 63. Specifically, if the open position 2 of the opening 10 of the box-type carrier is the position shown in FIG. 35C, the end position of the shutter curtain 5 (the end position in the open position 2 direction side) is the auxiliary panel. It becomes body 65.

  As described above, the panel body 61 is connected to the shutter curtain 5 to determine the end position of the shutter curtain 5 (the end position in the two open positions) or the panel body 61 and the auxiliary panel body 63 to the shutter curtain 5. Alternatively, by connecting the auxiliary panel body 65 and setting the end position of the shutter curtain 5 (end position in the open position 2 direction side), the end position of the shutter curtain 5 (open position 2 direction end position). ) Exceeds the open position 2 of the opening 10 of the box-type carrier (becomes higher), so that the end position of the shutter curtain 5 (the end position in the opening position 2 direction side) and the open position of the opening 10 of the box-type carrier. 2 can be eliminated. As described above, since the end position of the shutter curtain 5 (end position in the opening position 2 direction side) is adjusted with respect to the opening position 2, the shutter curtain 5 is moved to the opening position 2 of the opening 10 of the box-type carrier. Even if the shutter curtain 5 moves between the closed position 3 (even if the guide rails 4 and 4 are moved), the end of the shutter curtain 5 (the end position in the opening position 2 direction side) moves the shutter curtain 5 ( The length is adjusted so as not to contact the winding portion including the rotating shaft 40, the drum 37, and the like (for controlling the movement) (the moving direction of the shutter curtain 5).

  In FIG. 36, an adjustment panel body that adjusts the entire length of the shutter curtain 5 (the length along the moving direction of the shutter curtain 5) is provided at the end position of the shutter curtain 5 (the end position in the opening position in two directions). A certain panel body 61 and an auxiliary panel body 63 connected to the panel body 61 are shown. In this example, the connection between the panel body 61 and the auxiliary panel body 63 is performed using bolts and nuts, which are fixing members, as shown in FIG. In FIG. 36, a gap v occurs between the open position 2 and the end position of the shutter curtain 5 (the end position in the open position 2 direction) only with the panel body 61 on the open position 2 direction side of the shutter curtain 5. . In order to eliminate the gap v, the auxiliary panel body 63 is connected to the panel body 61 and is set at the end position of the shutter curtain 5 (the end position on the side of the open position 2 direction), so that the open position 2 and the entire shutter curtain 5 are formed. The length is adjusted.

  In other words, when the shutter curtain 5 closes the opening 10 of the box-type carrier, the end of the auxiliary panel body 63 comes to a position (higher position) beyond the open position 2 of the opening 10 of the box-type carrier. Therefore, as shown in FIG. 36, the auxiliary panel body 63 located at the end position (end position in the opening position 2 direction side) of the shutter curtain 5 is higher than the opening position 2 of the opening 10 of the box-type carrier, A gap v is not generated between the open position 2 of the opening 10 of the box-type carrier and the end of the auxiliary panel body 63. However, when the end position of the shutter curtain 5 (the end position in the opening position 2 direction side) is significantly higher than the opening position 2 of the opening 10 of the box-type carrier, the shutter curtain 5 is moved to the opening of the box-type carrier. When moving between the open position 2 and the closed position 3 of 10, there is a possibility that the take-up portion including the rotating shaft 40 and the drum 37 may be contacted. Therefore, the end position of the shutter curtain 5 (the end position in the opening position in the two directions) should not be in contact with the winding section including the rotating shaft 40 and the drum 37, and the opening of the box-type carrier should be considered. The panel body 61, the auxiliary panel body 63, or the auxiliary panel body 65 must be appropriately selected so as to eliminate the gap with the opening position 2 of the part 10.

  Next, the inside of the guide rails 4 and 4 at the end position (the end in the open position 2 direction side) of the shutter curtain 5 connecting the panel body 61 and the auxiliary panel body 63 shown in FIG. The trajectory of the movement will be described with reference to FIG. In the present example shown in FIG. 36, the end position of the shutter curtain 5 (the end position in the opening position in two directions) is the auxiliary panel body 63, and a description will be given centering on the locus of the auxiliary panel body 63. First, the lowermost panel body 7 (not shown) of the shutter curtain 5 is manually moved, and the shutter curtain 5 is moved from the open position 2 to the closed position 3 according to the solid arrow in FIG. The panel body 61 and the auxiliary panel body 63 move from the horizontal rails 19 and 19 in the state (f) to the connecting rails 20 and 20 in the state (e). Further, when the panel body 7 at the lowermost end of the shutter curtain 5 is moved from the open position 2 to the closed position 3, the panel body 61 and the auxiliary panel body 63 change from the state (E) in the connecting rails 20 and (E). ) And (c), and the auxiliary panel body 63 starts a trajectory drawing an arc.

  Further, when the panel body 7 at the lowermost end of the shutter curtain 5 is further moved from the open position 2 to the closed position 3, the panel body 61 and the auxiliary panel body 63 are moved from the state (C) in the connection rails 20 and 20 (C). Move to the state of b). At this time, the panel body 61 and the auxiliary panel body 63 move toward the vertical rails 18 and 18 along the connecting rails 20 and 20, and the auxiliary panel body 63 rotates along with the rotating shaft 40 along a circular arc orbit. , 37 (winding unit). Since the length of the auxiliary panel body 63 is set to an appropriate length (the end position of the shutter curtain 5 (the end position in the opening position 2 direction side) (the auxiliary panel body 63) is adjusted with respect to the opening position 2. Therefore, the robot moves away from the drums 37 and 37 while drawing a small arc trajectory that approaches but does not touch. Finally, the panel body 61 and the auxiliary panel body 63 move from the connecting rails 20 and 20 in the state (a) to the vertical rails 18 and 18 in the state (a).

  Although the case where the panel body 7 at the lowermost end of the shutter curtain 5 is moved from the open position 2 to the closed position 3 has been described above, the same applies to the case where the panel body 7 is moved from the closed position 3 to the open position 2. First, the panel body 7 at the lowermost end of the shutter curtain 5 is manually moved from the closed position 3 to the open position 2 according to the dotted arrow in FIG. The panel body 61 and the auxiliary panel body 63 move from the inside of the vertical rails 18 and 18 in the state of (A) to the connecting rails 20 and 20 in the state of (A). The auxiliary panel body 63 enters the connecting rails 20, 20 at an angle to the horizontal rails 19, 19 in a diagonal direction with respect to FIG. The lowermost panel body 7 of the shutter curtain 5 is further manually moved from the closed position 3 to the open position 2. The panel body 61 and the auxiliary panel body 63 move from the state (a) in the connecting rails 20 and 20 to the state (c).

  At this time, the panel body 61 and the auxiliary panel body 63 move toward the horizontal rails 19, 19 along the connecting rails 20, 20, and the auxiliary panel body 63 starts a trajectory that draws an arc, and the drum rotating together with the rotary shaft 40. 37, 37 (winding unit). Since the length of the auxiliary panel body 63 is set to an appropriate length (the end position of the shutter curtain 5 (the end position in the two open positions) (the auxiliary panel body 63) is adjusted with respect to the open position. Therefore, the robot moves away from the drums 37 and 37 while drawing a small arc trajectory that approaches but does not touch. Further, when the panel body 7 at the lowermost end of the shutter curtain 5 is further moved from the closed position 3 to the open position 2, the panel body 61 and the auxiliary panel body 63 are moved from the state (C) in the connection rails 20 and 20. It moves to the state of (d) and (e) and approaches the horizontal rails 19,19. Finally, the panel body 61 and the auxiliary panel body 63 move from the connecting rails 20 and 20 in the state (E) to the horizontal rails 19 and 19 in the state (F).

  In this example, the case where the end position of the shutter curtain 5 (the end position in the opening position 2 direction side) is the auxiliary panel body 63 has been described. Depending on the height), the end position of the shutter curtain 5 (the end position in the two open positions) may be the panel body 61 or the auxiliary panel body 65. Even in such a case, the same operation as the auxiliary panel body 63 shown in this example is performed by the panel body 61 or the auxiliary panel body 65 at the end position of the shutter curtain 5 (the end position in the opening position in two directions). Will do.

  As shown in FIGS. 38 (a) and 38 (b), the conventional shutter curtain 5 has long panel bodies 66, 67, etc. attached to the end positions of the shutter curtain 5 (end positions in two open positions). Was. Then, according to the size of the opening 10 such as a box-type carrier on which the shutter curtain 5 of the panel shutter 1 is mounted, the panel body 66 attached to the end position of the shutter curtain 5 (the end position in the opening position in two directions). , 67 were cut along cutting lines (two-dot chain lines) 68, 69 shown in FIGS. In this way, by cutting the panel bodies 66 and 67 at the end positions of the shutter curtain 5 (end positions in the opening position 2 direction side), the shutter curtain 5 is opened from the opening position 2 of the opening 10 such as a box-type bed. The end position (open position 2 direction end position) is raised to eliminate the gap between the open position 2 and the end position of the shutter curtain 5 (open position 2 direction end position).

  Further, at the time of cutting along the cutting lines (two-dot chain lines) 68 and 69 shown in FIGS. 38A and 38B, the end position of the shutter curtain 5 (the end position in the opening position 2 direction side) with respect to the opening position 2. In addition to adjusting the shutter curtain 5, the shutter curtain 5 moves between the open position 2 and the closed position 3 of the opening 10 of the box-type carrier, and the end portion of the shutter curtain 5 (the open end position in the two directions). Needs to be adjusted to a length that does not contact the winding portion including the rotating shaft 40 and the drum 37 (length along the moving direction of the shutter curtain 5). In particular, when the end position of the shutter curtain 5 (the end position on the side in the open position 2 direction) moves between the open position 2 and the closed position 3, the orbit of the arc drawn is reduced, and the shutter curtain 5 is compact. In order to realize a proper fit (storage), the positions of the cutting lines 68 and 69 of the panel bodies 66 and 67 must be carefully selected. However, the cutting for realizing a compact fit (storage) of the shutter curtain 5 is performed. Selection of the positions of the lines 68 and 69 has not been easy.

  Therefore, the panel body 61 and the auxiliary panel bodies 63 and 65 according to the present invention are determined by the size of the opening 10 such as the box-type carrier on which the shutter curtain 5 is mounted (corresponding to the open position 2 of the opening 10 such as the box-type carrier). By properly using the shutter curtain 5, the length of the shutter curtain 5 (the length along the moving direction of the shutter curtain 5) can be set to an appropriate length. That is, after the panel shutter 1 is attached to the opening 10 such as a box-type carrier, the panel body 61 at the end position (the end position in the opening position 2 direction side) of the shutter curtain 5 is opened. If it is located at an appropriate position with respect to the open position 2 of 10, it is not necessary to attach the auxiliary panel 63 or the auxiliary panel 65.

  After the panel shutter 1 is attached to the opening 10 such as a box-type carrier, the end position of the shutter curtain 5 (the end position in the opening position 2 direction side) is set to the open position 2 of the opening 10 such as the box-type carrier. If it is lower (when there is a gap between the end position of the shutter curtain 5 (the end position in the opening position 2 direction side) and the opening position 2 of the opening 10 such as a box-type carrier), the shutter curtain The auxiliary panel body 63 or the auxiliary panel body 65 is attached to the panel body 61 at the end position of the shutter curtain 5 (open position 2 direction side end position), and the end position of the shutter curtain 5 (open position 2 direction side end position). ) Is adjusted (finely adjusted) to an appropriate position with respect to the open position 2 of the opening 10 such as a box-type carrier.

  That is, not only is the end position of the shutter curtain 5 (end position in the opening position 2 direction side) higher than the opening position 2 of the opening 10 such as a box-type carrier, but also the end position of the shutter curtain 5 (open position). When the shutter curtain 5 moves between the open position 2 and the closed position 3 by appropriately using the auxiliary panels 63 and 65 connected to the panel body 61 at the two-direction side end position), the drum as a winding unit is used. The trajectory of the arc of the auxiliary panel body 63 or the auxiliary panel body 65 connected to the panel body 61 is reduced without contact with the 37 (rotating shaft 40) or the like, and compact accommodation (storage) of the shutter curtain 5 is realized. Will be.

  The connection between the panel body 61 and the panel body 6 at the end position of the shutter curtain 5 (the end position in the opening position in the two directions) is also performed using the panel body assembly jig 50 shown in Example 1. Have been In other words, as shown in FIG. 39, the tire portions 16a, 16a of the rollers 16, 16 are inserted into the ends of the vertical rails 18, 18 in the two open positions, and the first connecting portion 8 of the panel body 6 (the first opening 8a). ), And the shaft portions 16b, 16b of the rollers 16, 16 are placed on the first connecting portion 8 (first opening 8a). Then, the panel body 61 is placed on the panel body 6, and the second connecting portion 79 (second opening 79a) of the panel body 61 and the first connecting portion (first opening 8a) of the panel body 6 are connected. The shafts 16b, 16b of the rollers 16, 16 are fitted to each other to surround them.

  A state in which the shaft portions 16b, 16b of the rollers 16, 16 are surrounded by the first connecting portion 8 (first opening 8a) of the panel body 6 and the second connecting portion 79 (second opening 79a) of the panel body 61. In order to hold the panel body 61, a panel body assembling jig 50 as a temporary fixing member is attached to a portion of the guide rail 4 adjacent to the panel body 61. That is, in this state, only the panel body 61 is sandwiched and placed on the panel body 6 between the vertical rails 18, 18, and the panel body 61 is in a state of easily falling inside or outside the box-type carrier. . For this purpose, the panel assembly assembling jig 50 is attached to a position that does not hinder the attachment of the roller receiving member 21, for example, to a portion of the guide rail 4 corresponding to the center position of the panel 61 (FIG. 39). reference).

  By attaching the panel body assembling jig 50 to the guide rail 4, the panel body 61 which has been easily fallen inside or outside the box-type carrier becomes hard to fall. Then, as shown in FIG. 39, the receiving portions 21b, 21b of the roller receiving members 21, 21 are fitted to the back surface 61b of the panel body 61 and the back surface 6b of the panel 6, that is, the first opening 8a and the second opening 79a. Abutting on the mating portion, guides the arc-shaped end 21a of the roller receiving member 21 into the first opening 8a of the panel body 6 on the side of the first opening 8a, and engages with the first opening 8a. A substantially cylindrical tubular hole 15 is formed in contact with the two openings 79a together with the second openings 79a, and the bolts 11, 11 are assembled and fixed to the bolt holes 22, 22 of the roller receiving members 21, 21, respectively.

  Thus, the shaft portions 16b of the rollers 16, 16 between the first connecting portion 8 (first opening portion 8a) and the second connecting portion 79 (second opening portion 79a) by the roller receiving members 21, 21; By covering 16b, the rollers 16, 16 are positioned, and the connection between the panel body 61 and the panel body 6 is completed. The panel body 61 and the panel body 6 are swingably (bendably) connected. That is, since the first opening 8a and the arc-shaped end 21a of the roller receiving member 21 are in surface contact with the second opening 79a, the arc-shaped end 21a of the first opening 8a and the roller receiving member 21 are provided. And the second opening 79a can slide with each other.

  The method of using the panel body assembling jig 50 is as shown in Example 1. First, as shown in FIG. 18, the end 51 a of the flat member 51 of the panel body assembling jig 50 is inserted into a gap formed between the guide rail 4 (vertical rail 18) and the panel body 61. . Then, the relationship between the guide rail 4 (vertical rail 18) and the holding portion 50a of the panel body assembling jig 50 is set to the state shown in FIG. 19, and the butterfly screw of the push screw 52a screwed into the hole 52b. By rotating the head, the holding portion 50a of the panel assembly jig 50 is fixed by sandwiching the guide rail 4 (vertical rail 18). As a result, the end portion direction (folded portion 52g) of the holding portion 50b of the panel body assembling jig 50 becomes easy to contact the back surface 61b of the panel body 61, and the panel body 61 is supported and hardly falls down. As described above, the panel body 61 is in a state where the panel body 61 is hard to fall down, that is, is temporarily fixed, from a state where the panel body 61 easily falls down to the inside or outside of the box-type carrier (see FIG. 39).

(Example 3)
Next, Example 3 which is another example of the present invention will be described with reference to the drawings.

  FIG. 40 shows a rotating shaft 40 to which a resin pipe 41 according to the present invention is attached. The rotation shaft 40 has a function of supporting the shutter curtain 5 to move the shutter curtain 5. That is, the rotating shaft 40 is moved to the shutter curtain 5 via the wires 35, 35, etc. so that the shutter curtain 5 can move between the open position 2 and the closed position 3 of the opening 10 of the box-type carrier. It serves as a starting point. As shown in FIG. 40, the rotating shaft 40 is supported by brackets 43, 43 near the opening position 2 of the opening 10 of the box-type carrier and is rotatably mounted by bearings in the brackets 43, 43. ing. Drums 37, 37 are fixed to the rotating shaft 40 at both ends of the rotating shaft 40 adjacent to the brackets 43, 43 by fixing members of bolts 37a, 37a. With the drums 37, 37, the wires 35, 35 attached to the panel body 7 at the lowermost end of the shutter curtain 5 are wound or unwound.

  As shown in FIG. 40, a resin pipe 41 which is a pipe-like member serving as a buffer member is attached between one bracket 43 and a ring 44 for positioning the spring 42 which is an elastic member. Have been. As shown in FIG. 41, a spring 42, which is an elastic member for controlling and assisting the operation of the shutter curtain 5, is wound around the outer surface of the resin pipe 41. As described above, the resin pipe 41 is located between the rotating shaft 40 and the spring 42, and is provided to face the spring 42 with an appropriate clearance (gap 46). In this example, as shown in FIG. 41, a resin pipe 41 is shorter than a spring 42 and is provided inside the spring 42. However, the resin pipe 41 is not limited to being provided in the spring 42, and the resin pipe 41 may be provided beyond the spring 42.

  Next, the operation of the panel shutter 1 incorporating the rotating shaft 40 to which such a resin pipe 41 is attached when the shutter curtain 5 moves from the open position 2 to the closed position 3 will be described. The panel body 7 at the lowermost end of the shutter curtain 5 is moved from the open position 2 to the closed position 3. At this time, the wires 35, 35 attached to the panel body 7 at the lowermost end of the shutter curtain 5 are rewound from the drums 37, 37 in the closed position 3 direction. With the rewinding of the wires 35, the drums 37, 37 also rotate in the direction of arrow A shown in FIG. 28, and the rotating shaft 40 also rotates in the direction of arrow A. The rotation of the rotary shaft 40 in the direction of arrow A is transmitted to the spring 42 wound on the rotary shaft 40, and the spring 42 cancels the force acting on the shutter curtain 5 in the closing position 3 direction due to its own weight as much as possible. Since the function of urging in the two directions of the opening position works for the purpose, the function of rotating the rotary shaft 40 in the direction in which the wires 35 are wound is transmitted.

  At this time, the spring 42 in the longitudinal gap 46 of the rotating shaft 40 between the rotating shaft 40 and the spring 42 reciprocates along the cross-sectional direction of the rotating shaft 40 by bending due to the flexibility of the spring 42 ( Rocking). The swing causes the spring 42 to swing in a direction in which the spring 42 comes into contact with the rotating shaft 40. Since the resin pipe 41 is attached between the rotating shaft 40 and the spring 42, the spring 42 It is easy to contact with the pipe 41 made from. When the spring 42 comes into contact with the resin pipe 41, the swing of the spring 42 is easily absorbed by the elasticity and flexibility of the resin pipe 41. As a result, the spring 42 does not easily come into direct contact with the rotating shaft 40, and it is possible to make it difficult to generate contact noise due to the contact between the spring 42 and the rotating shaft 40. This is particularly effective when both the spring 42 and the rotating shaft 40 are made of a metal material. By arranging a resin pipe 41 between the spring 42 and the rotating shaft 40, It is possible to suppress the generation of the contact noise between the metallic materials due to the contact of the metal materials.

  When the shutter curtain 5 moves from the closed position 3 to the open position 2, the panel body 7 at the lowermost end of the shutter curtain 5 is moved from the closed position 3 to the open position 2. The wires 35, 35 attached to the panel body 7 at the lowermost end of the shutter curtain 5 are wound around the drums 37, 37 while maintaining a constant tension by the action of the spring 42 wound around the rotating shaft 40. Thus, the drums 37, 37 rotate in the direction of arrow B shown in FIG. In other words, by moving the lowermost panel body 7 to the open position 2, the rotating shaft is moved so that the wires 35, 35 attached to both side edges of the lowermost panel body 7 are wound around the drums 37, 37. The spring 42 wound around 40 acts to rotate the rotating shaft 40 in a direction (in the direction of arrow B shown in FIG. 28) in which the wires 35, 35 are wound around the drums 37, 37.

  Also at this time, the spring 42 reciprocates along the cross-sectional direction of the rotating shaft 40 due to the bending of the spring 42 in the longitudinal gap 46 of the rotating shaft 40 between the rotating shaft 40 and the spring 42 due to the flexibility of the spring 42. Exercise (rock). The swing causes the spring 42 to swing in a direction in which the spring 42 comes into contact with the rotating shaft 40. Since the resin pipe 41 is attached between the rotating shaft 40 and the spring 42, the spring 42 It is easy to contact with the pipe 41 made from. When the spring 42 comes into contact with the resin pipe 41, the swing of the spring 42 is easily absorbed by the elasticity and flexibility of the resin pipe 41. As a result, the spring 42 does not easily come into direct contact with the rotating shaft 40, and it is possible to make it difficult to generate contact noise due to the contact between the spring 42 and the rotating shaft 40. As described above, not only when the shutter curtain 5 is moved from the open position 2 to the closed position 3 but also when the shutter curtain 5 is moved from the closed position 3 to the open position 2, both the spring 42 and the rotary shaft 40 are made of metal. It is particularly effective when made of a material. The resin pipe 41 shown in this example is made of a metallic material, and is disposed between the spring 42 and the rotating shaft 40, thereby suppressing the generation of contact noise between the metallic materials due to the contact between them. It becomes possible to do.

  As described above, even when the shutter curtain 5 is moved between the open position 2 and the closed position 3, it is possible to make it difficult to generate contact noise due to the contact between the rotating shaft 40 and the spring 42. Although the resin pipe 41 is used in this example, the pipe 41 is limited to a pipe-shaped member before being attached to the rotary shaft 40 as long as it can function as a buffer between the spring 42 and the rotary shaft 40. Do not mean. In other words, a buffer member having a pipe-like shape that is substantially the same as the outer shape of the rotating shaft 40 by being attached to the rotating shaft 40 may be used. Therefore, it is also possible to wind a resin tape or the like around a position where the spring 42 of the rotating shaft 40 is attached to form a buffer member.

  Conventionally, as shown in FIG. 42, a steel spring 48 is wound directly around a rotating shaft 45 made of steel, and the shutter curtain 5 is moved between the open position 2 and the closed position 3. Therefore, when the rotating shaft 45 is rotated, the spring 48 swings due to the flexure of the spring 48 in the longitudinal gap 49 between the rotating shaft 45 and the spring 48 due to the flexibility of the spring 48. As a result, there was a situation in which the contact with the rotating shaft 45 was likely to occur and a contact noise was easily generated.

  For this purpose, the resin pipe 41 of the present invention is attached to a position on the rotating shaft 40 where the spring 42 is wound. As a result, when the spring 42 rotates, the spring 42 swings due to the flexibility of the spring 42 in the longitudinal gap 46 between the rotation shaft 40 and the spring 42 when the rotation shaft 40 rotates. Contact with the pipe 41. At the time of this contact, the swing of the spring 42 is easily absorbed by the elasticity and flexibility of the resin pipe 41. Then, the resin pipe 41 serves as a buffer between the spring 42 and the rotating shaft 40, and it is possible to reduce the occurrence of contact noise due to the contact between the spring 42 and the rotating shaft 40. Noise generated during operation of a certain panel shutter 1 can be reduced.

(Example 4)
Next, Example 4 which is still another example of the present invention will be described with reference to the drawings.

  FIG. 43 shows the roller 16 to which a resin tube 17 which is a hollow cylinder made of a resin such as nylon is attached. In this example, as shown in FIG. 43 (a), the resin tube 17 does not cover the tire portion 16a but covers most of the shaft portion 16b. That is, in this example, the shaft 16b is covered with the resin tube 17 by passing the resin tube 17 shorter than the shaft 16b of the roller 16 through the shaft 16b (FIG. 43 (b)). However, it is also possible to cover the entire shaft portion 16b with the resin tube 17 or cover the entire roller 16 with a resin member including the tire portion 16a. Further, the shaft 16b of the roller 16 can be covered with a resin tape instead of the resin tube 17 which is a hollow cylinder made of resin. For example, by covering the shaft 16b of the roller 16 with a resin tape, a resin-like tube (resin tube 17) can be formed on the shaft 16b of the roller 16.

  As shown in FIG. 44, the shaft portion 16b covered by the resin tube 17 of the roller 16 is connected to the adjacent panel members 6, 6 (the connection portion between the panel member 6 and the lowermost panel member 7). When inserted into the cylindrical hole 15 formed by the first opening 8a, the second opening 9a, and the arc-shaped end 21a of the roller receiving member 21, the shaft portion covered by the resin pipe 17 is included. 16b is supported so that it can be freely inserted and removed. Further, as shown in FIG. 45, a cylinder formed by abutting the roller receiving member 27 on the shaft portion 16b of the roller 16 covered with the resin tube 17 with the arcuate concave portion 30 of the lowermost panel body 7. When inserted into the hole 53, the shaft portion 16b covered with the resin tube 17 is supported so as to be freely inserted and removed. Then, as shown in FIG. 46 and FIG. 47, the cylindrical holes 15 of all the connecting parts of the adjacent panel bodies 6 (including the connecting part of the panel body 6 and the panel body 7 at the lowermost end), and The roller 16 having the shaft portion 16b covered with the resin tube 17 is inserted into and supported by the cylindrical hole 53 of the panel body 7 at the lowermost end from both width directions of the shutter curtain 5. Further, the tire portions 16a of the rollers 16 protruding from both side edges of the shutter curtain 5, as shown in FIGS. 46 and 47, pass through the guide rails 4, 4 provided on both side edges of the shutter curtain 5. It will roll (move).

  Next, regarding the operation of moving the shutter 16 between the open position 2 and the closed position 3 of the shutter curtain 5 to which the roller 16 having the shaft portion 16 covered with the resin pipe 17 as described above, the roller 16, the cylindrical hole 15, The description will be made focusing on the relationship with the cylindrical hole 53 of the panel body 7 at the lowermost end. First, the panel body 7 at the lowermost end of the shutter curtain 5 is moved from the open position 2 to the closed position 3 or from the closed position 3 to the open position 2. As shown in FIGS. 46 and 47, the tire portion 16a of the roller 16 starts rotating in the guide rails 4 and 4, and starts moving in the three closed positions or the two open positions. At the same time, the inside of the cylindrical hole 15 of the connecting portion between the adjacent panel bodies 6 (including the connecting portion between the panel body 6 and the lowermost panel body 7), and the cylindrical hole of the lowermost panel body 7 The shaft 16b of the roller 16 covered with the resin tube 17 in the roller 53 also starts rotating, and starts moving in the closed position 3 direction or the open position 2 direction.

  The shaft 16b covered by the resin tube 17 of the roller 16 is moved in either the closed position 3 direction or the open position 2 direction, and moves in the guide rails 4 and 4 of the tire portion 16a of the roller 16, and the shutter is moved. The cylindrical hole 15 of the connecting portion (including the connecting portion between the panel body 6 and the panel body 7 at the lowermost end) of the adjacent panel bodies 6 and 6 of the curtain 5 also moves, and the cylindrical hole 15 in the cylindrical hole 15 is moved. The shaft portion 16b covered by the resin tube 17 rotates in the gap between the shaft portion 16b covered by the resin tube 17 and the shaft portion 16b It comes into contact with the inner wall 15a (see FIG. 44). Similarly, the gap between the cylindrical hole 53 and the shaft portion 16b covered by the resin tube 17 in the cylindrical hole 53 of the panel body 7 at the lowermost end causes the shaft portion 16b covered by the resin tube 17 to fall within the gap. The shaft 16b covered with the resin pipe 17 comes into contact with the inner wall 53a of the cylindrical hole 53 while rotating at (see FIG. 45).

  At this time, since the shaft portion 16a is covered with the resin pipe 17, even if the shaft portion 16b is in contact with the inner wall 15a in the cylindrical hole 15, the shaft portion 16a is in contact with the inner wall 53a of the cylindrical hole 53 and the shaft portion 16b. Also, it is difficult to generate a contact sound. That is, the resin pipe 17 serves as a buffer between the inner wall 15a in the cylindrical hole 15 and the inner wall 53a in the cylindrical hole 53, and the shaft portion 16b, and the inner wall 15a in the cylindrical hole 15 and the inner wall 53a of the cylindrical hole 53; Direct contact with the shaft portion 16b can be easily avoided. For this reason, when the shutter curtain 5 is moved from the open position 2 to the closed position 3 or from the closed position 3 to the open position 2, contact between the cylindrical hole 15 and the cylindrical hole 53 due to the rotational movement of the roller 16 is performed. It is possible to suppress the generation of sound.

  In this example, by covering the shaft portion 16b of the roller 16 with the resin tube 17, the connection portion between the adjacent panel bodies 6, 6 (including the connection portion between the panel body 6 and the panel body 7 at the lowermost end) is also included. The generation of contact noise due to the contact between the inner wall 15a in the cylindrical hole 15 and the inner wall 53a in the cylindrical hole 53 of the panel body 7 at the lowermost end and the shaft portion 16b is suppressed. However, in order to suppress the contact noise between the inner wall 15a in the cylindrical hole 15 and the inner wall 53a in the cylindrical hole 53 and the shaft 16b, not only the shaft 16b of the roller 16 is covered with the resin pipe 17, but also the shaft 16b. Considering the strength of the shaft 16b, the shaft 16b may be made of a resin member. Further, in this example, the shaft 16b of the roller 16 is covered with the resin pipe 17, but it is also possible to simply wind a resin tape or the like around the shaft 16b of the roller 16, for example.

  Also, by changing the steel roller receiving member 21 and the roller receiving member 27 to the resin roller receiving member 21 and the roller receiving member 27, the shaft portion 16b of the roller 16, the inner wall 15a and the cylindrical hole The generation of the contact noise with the inner wall 53a in 53 can be suppressed. Further, by adhering a resin member to the inner wall 15a in the cylindrical hole 15 and the inner wall 53a in the cylindrical hole 53 for resin coking, the inner wall 15a in the cylindrical hole 15 and the inner wall 53a in the cylindrical hole 53 can be formed. Thus, direct contact of the roller 16 with the shaft portion 16b can be avoided, and generation of contact noise can be suppressed. In addition, the cylindrical hole 15 of the connecting portion between the adjacent panel bodies 6 (including the connecting portion between the panel body 6 and the lowermost panel body 7) and the cylindrical hole 53 of the lowermost panel body 7 are formed. The cylindrical holes of the connecting portions can also be made by attaching them to the adjacent panel bodies 6, 6 (including the adjacent panel bodies 6 and the lowermost panel body 7) and the lowermost panel body 7 later. It is also possible to suppress the generation of contact noise between the inner wall 15 a in the inner wall 15 and the inner wall 53 a in the cylindrical hole 53 and the shaft 16 b of the roller 16. In the above, the case where a resin member is used in order to suppress the generation of contact noise between the inner wall 15a in the cylindrical hole 15 and the inner wall 53a in the cylindrical hole 53 and the shaft portion 16b has been described. If the generation can be suppressed, the contact noise caused by the contact between the inner wall 15a in the cylindrical hole 15 and the inner wall 53a in the cylindrical hole 53 and the shaft portion 16b can be absorbed. It is possible to use it similarly to the member made of resin without being limited to.

  Conventionally, connecting portions of the adjacent panel members 6 (including a connecting portion between the panel member 6 and the lowermost panel member 7) and both width directions of the lowermost panel member 7 (both of the shutter curtains 5). The shaft portion 16b of the roller 16 was attached from the width direction). When the shutter curtain 5 moves between the closed position 3 and the open position 2, the tire portion 16 a of the roller 16 rotates in the guide rails 4 and 4, and the shaft portion 16 b of the roller 16 is adjacent. The rotational movement has been performed within the connecting portions of the panel bodies 6 and 6 and the panel body 7 at the lowermost end. At this time, along with the movement of the shutter curtain 5, the inner wall of the connecting portion between the adjacent panel members 6, 6 (including the connecting portion between the panel member 6 and the panel member 7 at the lowermost end) and the panel member 7 at the lowermost end. The inner wall and the shaft portion 16b of the roller 16 had to come into contact with each other, and the contact sound was easily generated.

  In the present invention, by covering the shaft portion 16b of the roller 16 with the resin tube 17 which is a resin member, the rotation of the roller 16 when the shutter curtain 5 moves causes the connecting portion between the adjacent panel bodies 6, 6 to be connected. The inner wall 15a in the cylindrical hole 15 and the inner wall 53a in the cylindrical hole 53 of the panel body 7 at the lowest end (including the connection part between the panel body 6 and the panel body 7 at the lowermost end), and the shaft of the roller 16 Generation of contact noise due to contact with the portion 16b can be suppressed. That is, the resin pipe 17 serves as a buffer between the inner wall 15a in the cylindrical hole 15 and the inner wall 53a in the cylindrical hole 53, and the shaft portion 16b, and the inner wall 15a in the cylindrical hole 15 and the inner wall 53a of the cylindrical hole 53; Since the shaft portion 16b of the roller 16 comes into contact with the resin tube 17 sandwiched therebetween, the inner wall 15a in the cylindrical hole 15 and the inner wall 53a in the cylindrical hole 53 directly contact the shaft portion 16b. As compared with the above, the generation of the contact sound can be suppressed, and the noise during the operation of the panel shutter 1 can be reduced.

  In addition, the moving direction of the shutter curtain 5 from Example 1 to Example 4 which is an example of the present invention is the vertical direction, but the shutter curtain 5 of the opening / closing device of the present invention is not limited to the vertical direction. It is possible to move in a horizontal direction or an inclined direction.
