Description

Technical Field

[0001] The present invention relates to a panel shutter.

Background Art

[0002] When the panels of a panel shutter are stored, they are stored in a vertical posture so as to overlap in the front-rear direction (inside-outside direction). However, there is a desire to prevent direct contact between the panel surfaces when the panels are stored.

[0003] The applicant of the present application has proposed a waterproof door that can maintain a water-stopping function even when a large water pressure acts on a door body in a water-stopping state using a panel shutter (Patent Document 1). Patent Document 1 has a first surface portion on the first side (outdoor side) and a second surface portion on the second side (indoor side), and closes a building opening to partition the first side and the second side, and abuts on the first surface portion of the door body in the fully closed state, and horizontal pressing means for pressing the door body horizontally from the first side to the second side. Even in such a waterproof door, there is a desire to prevent direct contact between the panel surfaces when the panels are stored.

[0004] Particularly, in a panel structure having a shape in which ribs are provided on the panel surface portion, when the panels are stored, there is a risk that the ribs on the surface portion of one adjacent panel contact the surface portion of the other panel, resulting in damage to the panel surface portion.

Problems to be Solved by the Invention

[0005] An object of the present invention is to prevent the panel surfaces from contacting each other in the panel storage posture.

Means for Solving the Problems

[0006] The technical means adopted by the present invention is In a panel shutter equipped with multiple panels, The visible surface of each panel consists of a first surface portion that faces the first side in a vertical orientation, and a second surface portion that faces the second side. Door stops are provided at least at both ends in the width direction of the first surface. When the panels are stored, the door stop is positioned between the first surface of one adjacent panel and the second surface of the other panel, in a nearly vertical position. It's a panel shutter. In one embodiment, the first side is either the outdoor side or the indoor side. In one embodiment, if a door stopper is provided on the first surface, a door stopper is not provided on the first surface of the bottom panel.

[0007] In one embodiment, the first side is the outdoor side, and the first surface is the outdoor side surface. The panel shutter includes a guide body that receives and guides both ends in the width direction of each panel, It includes a horizontal compression means for pressing the first surface of the panel, which is in a fully closed position, toward the indoor side. The widthwise ends of the first surface are located within the guide body and are equipped with a surface to be pressed by a horizontal compression means. The door stopper is positioned and protrudes from the outside of the surface to be pressed.

[0008] In one embodiment, each panel has ribs protruding from at least the first surface portion, extending in the panel width direction. The height of the door stop relative to the first surface is higher than the height of the rib relative to the first surface. In one embodiment, each panel is made of an aluminum profile, and the ribs are integrally formed by extrusion. In one embodiment, the length dimension of the rib is shorter than the width dimension of the first surface, and both ends of the first surface in the width direction are flat sections without ribs over the entire height.

[0009] In one embodiment, the first side is the outdoor side, and the first surface is the outdoor side surface. The panel shutter includes a guide body that receives and guides both ends in the width direction of each panel, It includes a horizontal compression means for pressing the first surface of the panel, which is in a fully closed position, toward the indoor side. The flat portion is at least partially located within the guide body and has a surface to be pressed by a horizontal compression means. In the flat portion, the door stop is positioned and protrudes from the outside of the surface to be pressed. [Effects of the Invention]

[0010] In this invention, door stops are provided on both ends in the width direction of the first surface of the panel, thereby preventing the first surface from coming into contact with the second surface of an adjacent panel when the panel is stored. In particular, even if ribs are provided on the first surface, the second surface will not come into contact with the ribs and will not be damaged. In an embodiment in which the panel shutter is equipped with a horizontal compression means, the door stop is positioned and protrudes from the outside of the surface to be pressed by the horizontal compression means, so that when the panel is raised or lowered, the door stop does not come into contact with the horizontal compression means, and when horizontal compression occurs, the horizontal compression means does not press against the door stop.

[Embodiments for Carrying out the Invention]

[0012] [A] Panel shutter The panel shutter according to the present embodiment will be described. As shown in FIG. 1, the panel shutter includes a shutter curtain composed of a plurality of panels 1, and left and right guide bodies 2 erected at both ends in the width direction of the building opening and guiding both end portions in the width direction of the panel 1 in a vertical posture. In FIG. 2, the left side of the panel 1, that is, the shutter curtain, is the outdoor side, and the right side is the indoor side. In FIG. 3, the upper side of the panel 1 is the outdoor side, and the lower side is the indoor side.

[0013] [A-1] Panel The panel 1 is a horizontally rectangular element having a predetermined thickness and extending in the opening width direction, and is integrally formed from an aluminum extrusion profile. As shown in FIGS. 5 and 6, the panel 1 includes an outdoor side surface portion 100, an indoor side surface portion 101, an upper end surface 102, and a lower end surface 103. In the fully closed state (vertical posture) of the opening, the outdoor side surface portion 100 of the panel 1 faces the outdoor side, and the indoor side surface portion 101 faces the indoor side. The lower end surface 103 of the panel 1 in the present embodiment has an upwardly curved concave surface in a side view, and the upper end surface 102 of the panel 1 has an upwardly curved convex surface in a side view.

[0014] As shown in Figures 4 to 6, in the panel 1 according to this embodiment, horizontally extending ribs 3 are integrally formed on the outdoor side portion 100. In the illustrated configuration, three ribs 3 extend parallel to each other in the height direction, spaced apart from each other. The length of the ribs 3 according to this embodiment is shorter than the total width of the outdoor side portion 100 of the panel 1, and the ends of the ribs 3 in the length direction do not reach the ends of the outdoor side portion 100 of the panel 1 in the width direction. The ends of the outdoor side portion 100 in the width direction are flat portions 1000 without ribs 3 over the entire height.

[0015] In the shutter curtain according to this embodiment, door stops 4 are provided protruding from the ends of the outdoor side portions 100 of all panels 1 except the bottom panel 1', i.e., the ends of the flat portions 1000. The height of the door stops 4 is greater than the height dimension of the ribs 3. The door stops 4 function as a cushioning material, and the material of the door stops 4 is not limited as long as it is a material softer than the aluminum that forms the panel 1, with resin and rubber being examples. The door stops 4 according to this embodiment are small protrusions. In this embodiment, two door stops 4 are provided at each left and right end of the outdoor side portion 100 of the panel 1, spaced apart in the height direction (up and down direction) of the panel 1, for a total of four door stops 4, but the number of door stops 4 is not limited. In this embodiment, the panel 1 is divided into a plurality of hollow portions in the height direction, and except for the second hollow portion from the bottom, openings 1a are formed at both ends in the width direction of the hollow portions, making them open (see Figure 6A). The widthwise ends of the second hollow section from the bottom are closed by a cover body 1b, and a lower guide roller 1c is provided protruding from the cover body 1b. Openings 1a are formed at both widthwise ends of the hollow section where the door stopper 4 is provided, and the door stopper 4 can be replaced using the openings 1a. In this embodiment, the lower door stopper 4 is provided in the hollow section directly above the hollow section whose widthwise ends are closed (the hollow section where the lower guide roller 1c is provided).

[0016] [A-2] Guide body As shown in Figure 3, the guide body 2 is formed in a U-shape in cross-section from spaced-apart opposing exterior-facing walls 20 and interior-facing walls 21, and a bottom wall 22 extending in the depth direction, and is a long member that extends to the entire height of the opening. The front edges 200 and 210 of the exterior-facing walls 20 and interior-facing walls 21 are bent so that they face each other. The front edge 200 extends perpendicularly to the exterior-facing wall 20 from the tip of the exterior-facing wall 20 toward the interior, and the front edge 210 extends perpendicularly to the interior-facing wall 21 from the tip of the interior-facing wall 21 toward the exterior. The widthwise end of the panel 1 is received in the opening groove between the tips of the front edges 200 and 210. The outer surfaces of the front edges 200 and 210 of the exterior wall 20 and interior wall 21 are each provided with a pair of fins 26, which are elastic elements made of elongated elastic rubber extending in the height direction. The fins 26 come into contact with the exterior side portion 100 and the interior side portion 101 of the panel 1 when the panel 1 is raised or lowered and when it is fully closed.

[0017] [A-3] Panel lifting and lowering operation As shown in Figure 3, a support shaft 10 equipped with guide rollers 11 is provided protruding from the upper side of both ends in the width direction of each panel 1, and each panel 1 is connected to a chain 14 via the support shaft 10 and suspended to form a shutter curtain. Although the chain is omitted in Figure 2 and other figures, it should be noted that the configuration of suspending each panel by a chain in a panel shutter is well known to those skilled in the art. When the opening is fully closed, each panel 1 is in a vertical position with both ends in the width direction supported within the guide body 2, and when the opening is fully open, it is suspended in a vertical position from a storage rail 6 that extends within the storage space 5 of the panel 1 above the opening.

[0018] The upper end of the guide body 2 extends into the storage space 5 above the opening and is equipped with an upper extension 2' (see Figure 2) that guides the guide rollers 11 at both ends in the width direction of the panel 1. The upper extension 2' is configured to be able to contact the guide rollers 11 from both the exterior and interior sides. In the storage space 5 above the opening, a sprocket 50 is provided located approximately at the upper end of the upper extension 2' for winding the chain 14 around it. The opening / closing mechanism M rotates the sprocket 50 to lift or unwind the chain 14, thereby raising or lowering the panel 1 to open or close the building opening.

[0019] [A-4] Panel storage The storage space 5 for panel 1 above the opening extends from above the opening toward the interior, and a storage rail 6 is provided in the storage space 5 that extends in a gently downward sloping manner from the front toward the rear (interior). Panel 1, which has been moved into the storage space 5 by the lifting of the chain 14, is transferred to the storage rail 6 via the sprocket 50, and the panel 1 is sequentially moved toward the rear of the storage space 5 with the guide roller 11 guided by the storage rail 6, and is held and stored in a state where it hangs down parallel to each other. Even in the stored position, panel 1 is in a vertical position, with the outdoor side portion 100 facing the front side of the storage space 5 and the indoor side portion 101 facing the rear side of the storage space 5.

[0020] When Panel 1 is stored and in its stored position, multiple Panels 1 are arranged side by side in a vertical position. In two adjacent Panels 1 in a vertical position, the outdoor side portion 100 of one (rear) Panel 1 and the indoor side portion 101 of the other (front) Panel 1 are in close proximity to each other. However, a door stopper 4 is positioned between the outdoor side portion 100 of the rear Panel 1 and the indoor side portion 101 of the front Panel 1. The door stopper 4, which protrudes from both ends in the width direction of the outdoor side portion 100 of the rear Panel 1, abuts against both ends in the width direction of the indoor side portion 101 of the front Panel 1. This prevents the aluminum panel surfaces from directly contacting each other, thus preventing scratches on the panel surfaces. The height dimension (protrusion dimension) of the door stopper 4 is greater than the height dimension (protrusion dimension) of the rib, so that the rib 3 protruding from the outdoor side portion 100 of one Panel 1 does not come into contact with the indoor side portion 101 of the other Panel 1. Furthermore, the door stopper 4 provided on the outdoor side portion 100 of one panel 1 abuts against the indoor side portion 101 of the other panel 1, thereby restricting contact between the metal (aluminum) panel surfaces and suppressing the generation of contact noise between metal components.

[0021] [B]Water stop structure The panel shutter according to this embodiment is configured as a waterproof door by providing a watertight structure to the panel shutter in its fully closed state. In this embodiment, the means for making the fully closed panel shutter watertight consists of a first compression mechanism 7 that compresses each panel 1 in the fully closed state vertically downward, and a second compression mechanism 8 that compresses all the panels 1 compressed vertically by the first compression mechanism 7 together horizontally toward the interior. The watertight structure will be described below, but for details of the watertight structure, see, for example, Patent Document 1.

[0022] [B-1] First compression mechanism (vertical compression mechanism) As shown in Figure 1, multiple first compression mechanisms 7 are provided in the storage space above the opening, extending in the direction of the opening width. As shown in Figure 1, in this embodiment, three first compression mechanisms 7 are provided at intervals in the direction of the opening width. More specifically, one first compression mechanism 7 is provided in the center in the direction of the opening width, and first compression mechanisms 7 are provided at positions closer to the left and right guide bodies 2. The number of first compression mechanisms 7 is not limited, and the appropriate number is selected according to the width dimension (opening width dimension) of the panel 1, etc.

[0023] The first compression mechanism 7, when the opening is fully closed, lowers the piston rod 71 and presses the pressing portion 72 against the upper end of the uppermost panel 1, thereby compressing each panel in the fully closed state vertically downwards. Three concave pressing portions 16 are formed on the upper end of the uppermost panel 1, corresponding to the three first compression mechanisms 7 (see Figure 4). The first compression mechanism 7 is positioned offset to the outside relative to the lifting path of the panels 1 so as not to obstruct the lifting and lowering of the panels 1 in the storage space above the opening. Therefore, in order to press the upper end of the uppermost panel 1 in the fully closed state, the rod 71 of the power cylinder 70 protrudes diagonally downwards, but the pressing portion 72, which is a link mechanism, applies a pressing force vertically to the upper end of the uppermost panel 1.

[0024] The first compression mechanism 7 includes a first limit switch 73 and a second limit switch 74. The first limit switch 73 and the second limit switch 74 constitute a vertical compression state detection means. In this embodiment, when the first limit switch 73 turns from OFF to ON, it is the time when the compression of the first compression mechanism 7 is released, and when the second limit switch 74 turns from OFF to ON, it is the time when the compression of the first compression mechanism 7 is completed.

[0025] [B-2] Second compression mechanism (horizontal compression mechanism) As shown in Figure 1, the storage space above the opening is provided with second compression mechanisms 8 at the left and right ends in the width direction of the opening. Similar to the first compression mechanism 7, the second compression mechanism 8 is positioned offset to the outside with respect to the lifting path of the panel 1 so as not to obstruct the lifting and lowering of the panel 1 in the storage space above the opening. As shown in Figures 8 and 9, the second compression mechanism 8 includes a power cylinder 80, which is exemplified as an actuator placed in the storage space above the opening, and a horizontal pressing member 23 that is linked to the vertical movement of the piston rod 81 of the power cylinder 80. The horizontal pressing member 23 is formed in a rectangular shape in cross-section and is provided on the inner surface of the front end of the exterior-facing wall 20 of the guide body 2.

[0026] The horizontal pressing member 23 comprises a long, U-shaped first member (outdoor side member) 230 extending vertically along the guide body 2, and a long, U-shaped second member (indoor side member) 231 extending vertically along the guide body 2. The first member 230 is connected to the outdoor side facing wall 20 of the guide body 2 by screws (not shown), with the first member 230 being a fixed element and the second member 231 being a movable element. The second member 231 has a vertical pressing surface 2310, and when compressed, the pressing surface 2310 contacts the outdoor side portion 100 of the panel 1 and presses toward the indoor side. As shown in Figures 8 and 9, the upper end of the pressing surface 2310 is a tapered inclined surface 2311. The second member 231 moves horizontally away from and toward the first member 230 via a link mechanism and an operating mechanism described below.

[0027] The linkage mechanism comprises a first link 232 and a second link 233, and by changing the angle between the first link 232 and the second link 233, the second member 231 moves horizontally apart from and closer to the first member 230. The first end of the first link 232 is rotatably connected to the first member 230 at predetermined intervals in the height direction via a first shaft 2320, the first end of the second link 233 is rotatably connected to the second member 231 at predetermined intervals in the height direction via a second shaft 2330, and the second end of the first link 232 and the second end of the second link 233 are rotatably connected via a third shaft 2340.

[0028] The first link 232 and the second link 233 are both block-shaped link blocks. The first end of the first link 232 is provided with a first shaft 2320 that penetrates the block, and the first end of the second link 233 is provided with a second shaft 2330 that penetrates the block. The second end of the first link 232 consists of a pair of spaced-apart opposing pieces, and the second end of the second link 233 is rotatably clamped between these pieces. The second end of the second link 233 also consists of a pair of spaced-apart opposing pieces, and an operating rod 234 is clamped between these pieces, allowing rotation of the second end of the second link 233 relative to the operating rod 234.

[0029] The operating rod 234 is an elongated member that extends vertically along the guide body 2, and in one embodiment, it is formed by connecting a plurality of elongated members in the vertical direction. Third shafts 2340 are connected to the operating rod 234 at predetermined intervals in the height direction, and the upper end of each shaft is connected to the tip of the piston rod 81 of the power cylinder 80. In other words, the operating mechanism consists of the operating rod 234 and the power cylinder 80 that moves the operating rod 234 up and down. The power cylinder 80 is positioned with the piston rod 81 facing downwards, and the piston rod 81 is connected to the upper end of the operating rod 234 via a connecting mechanism.

[0030] The connecting mechanism consists of a link 82 and a base 820 that rotatably supports the midpoint of the link 82 via an axis 82'. The lower end of the piston rod 81 is rotatably connected to the first end of the link 82, and the upper end of the operating rod 234 is rotatably connected to the second end of the link 82 via a rod head 2341 and a suspension rod 2342. The mechanism is configured such that the operating rod 234 is pulled up in conjunction with the downward protruding movement of the piston rod 81.

[0031] The first member 230 is provided with a pair of guides 235 at predetermined intervals in the height direction to correspond to the link mechanism, and the second shaft 2330 and the third shaft 2340 are guided by guide grooves 236 formed in the guides 235. The second shaft 2330 is provided with a guide roller 2331, and the second shaft 2330 reciprocates horizontally as the guide roller 2331 is guided by the horizontal portion of the guide groove 236. In other words, the second member 231 moves horizontally in conjunction with the upward movement of the operating rod 234, and the pressing surface 2310 presses against the outdoor side portion 100 of the panel 1, thereby pressing the indoor side portion 101 against the watertight rubber member 24.

[0032] The second compression mechanism 8 includes a first limit switch 83 and a second limit switch 84. The first limit switch 83 and the second limit switch 84 constitute a horizontal compression state detection means. In this embodiment, when the first limit switch 83 turns from OFF to ON, it is the time when the compression of the second compression mechanism 8 is released, and when the second limit switch 84 turns from OFF to ON, it is the time when the compression of the second compression mechanism 8 is completed.

[0033] [B-3] Watertight structure of the panel A watertight rubber seal 12 is provided on the upper end surface 102 of each panel 1, except for the topmost panel 1, extending over its entire width. When the opening is fully closed, the lower end of the upper panel 1 and the upper end of the lower panel 1 of two vertically adjacent panels 1 are pressed together via the watertight rubber seal 12, thereby providing a watertight seal between vertically adjacent panels. A watertight rubber seal 13 is provided on the lower end of the lowest panel 1, extending over its entire width. When the opening is fully closed, the watertight rubber seal 13 is pressed against the floor surface, providing a watertight seal at the bottom of the shutter curtain. In other words, by compressing the fully closed shutter curtain vertically from its top end toward the floor surface, a watertight seal is achieved between vertically adjacent panels 1 and between the lowest panel 1 and the floor surface.

[0034] [B-4] Movable middle pillar As shown in Figure 1, in this embodiment, the waterproof door is equipped with a movable central column 15. The central column 15 is a reinforcing central column that supports the shutter curtain in a watertight state from the interior side, and is located on the interior side of the panel 1 in a fully closed state, and is installed in close proximity to the interior side portion 101 of the panel 1. In the illustrated embodiment, the waterproof door is equipped with three central columns 15, but the number of central columns 15 is not limited, and the appropriate number is selected according to the width dimension (opening width dimension) of the panel 1, the water pressure (water level height), etc.

[0035] [B-5] Relationship between the widthwise edges of the panel and the guide body As shown in Figure 3, the widthwise end of each panel 1 is received in the opening between the horizontal pressing member 23 on the outdoor side and the watertight rubber member 24 on the indoor side, and the outdoor circumferential surface of the guide roller 11 at the tip of the support shaft 10 protruding from the widthwise end is in contact with or close to the guide member 25 provided on the bottom side of the guide body 2. By moving the chain 14 up and down, each panel 1 moves vertically up and down, with its outdoor side and indoor side in contact with the fins 26 respectively, and the outdoor circumferential surfaces of the guide rollers 11 of the support shafts 10 at both ends in the widthwise direction being guided by the guide member 25, and both ends in the widthwise direction being guided by the watertight rubber member 24.

[0036] When the opening is fully closed, most of the flat portions 1000 at both widthwise ends of the outdoor side portion 100 of panel 1 become the pressure-receiving surfaces 100A located within the guide body 2. Because the outdoor circumferential surface of the guide roller 11 contacts the guide member 25, during normal opening and closing and in the normal fully closed state, the metal horizontal pressing member 23 and the pressure-receiving surfaces 100A at the widthwise ends of the outdoor side portion 100 of panel 1 are separated by a clearance, thus restricting contact between the horizontal pressing member 23 and the pressure-receiving surfaces 100A of the outdoor side portion 100 of panel 1. Furthermore, since the door stop 4 is located and protrudes from the outside of the pressure-receiving surfaces 100A on the outdoor side portion 100 of panel 1, the horizontal pressing member 23 and the door stop 4 do not come into contact when the shutter curtain is raised or lowered. Also, as shown in Figure 3, the rib 3 is not located within the guide body 2.

[0037] The horizontal pressing member 23 and the watertight rubber member 24 face each other with the widthwise end of the panel 1 interposed between them. The indoor side surface of the guide roller 11 is free (not guided by the member), and the guide roller 11 can move inward as the panel 1 moves inward. By pressing the pressed surfaces 100A of the flat portions 1000 at both widthwise ends of the outdoor side portion 100 of the panel 1 inward with the horizontal pressing member 23, the widthwise ends of the indoor side portion 101 of the panel 1 are pressed against the watertight rubber member 24, and a watertight structure is obtained that extends in the height direction at both widthwise ends of the shutter curtain.

[0038] [B-6] In the panel shutter configured in this way, when the opening is fully closed, the opening / closing mechanism M rotates the sprocket 50 in the chain lifting direction. As the chain 14 rises, each panel 1, which is in a vertical position in the fully closed state, is guided by the vertically oriented guide body 2 at both ends in the width direction and rises. Starting from the uppermost panel 1, the panels are sequentially transferred to the storage rail 6 extending laterally from the upper extension 2' of the guide body 2, and are stored parallel to each other in the storage space 5, opening the opening.

[0039] At this time, the indoor side portion 101 of the next panel 1 to be stored will be close to the outdoor side portion 100 of the panel 1 that was stored first in the storage space 5. However, the door stoppers 4 that protrude from both ends in the width direction of the outdoor side portion 100 of the first panel 1 to be stored will come into contact with both ends in the width direction of the indoor side portion 101 of the later-stored panel 1, thereby preventing the indoor side portion 101 of the later-stored panel 1 from coming into contact with the ribs 3 that protrude from the outdoor side portion 100 of the first panel 1 to be stored.

[0040] Since the door stop 4 is positioned and protrudes from the outside of the pressed surface 100A on the outdoor side portion 100 of panel 1, the horizontal pressing member 23 and the door stop 4 do not come into contact when the shutter curtain is raised.

[0041] With the opening fully open, when the opening / closing mechanism M rotates the sprocket 50 in the chain payout direction, the panels 1, which were stored parallel to each other, are sequentially pulled out from the rear of the storage space toward the sprocket 50, with the guide rollers 11 at both ends in the width direction being guided by the storage rail 6. As they pass the sprocket 50, they descend while being guided by the guide body 2, with each other in a vertical position in the height direction, and the opening is closed.

[0042] Since the door stop 4 is positioned and protrudes from the outside of the pressed surface 100A on the outdoor side portion 100 of panel 1, the horizontal pressing member 23 and the door stop 4 do not come into contact when the shutter curtain is lowered.

[0043] When the shutter curtain is lowered, the upper end of the lower panel and the lower end of the upper panel are separated in any two adjacent panels 1. When the shutter curtain is lowered, after the lower end of the lowest panel 1 touches the floor, the shutter curtain continues to descend a predetermined distance, causing the upper end of the lower panel and the lower end of the upper panel to come into contact in any two adjacent panels 1, resulting in a fully closed state. Furthermore, as will be described in detail later, the fully closed shutter curtain is compressed vertically, resulting in a vertically compressed state. In the vertically compressed state of the shutter curtain, the watertight rubber 12 seals the space between the vertically adjacent panels 1 in a watertight manner, and the watertight rubber 13 seals the space between the lower end of the lowest panel 1 and the floor surface in a watertight manner.

[0044] When the shutter curtain, which is in a vertically compressed state, is further compressed horizontally to become horizontally compressed, the indoor side portion 101 of panel 1 is pressed against the watertight rubber member 24, sealing both ends in the width direction of the opening in a watertight manner. In this embodiment, by making the piston rod 81 protrude downward to the position shown in Figure 8, the operating rod 234 is pulled up vertically, and in conjunction with the upward movement of the operating rod 234, the second member 231 is pushed toward panel 1 so as to move away from the first member 230 and comes into contact with the pressed surface 100A of the outdoor side portion 100 at the widthwise end of panel 1, and the indoor side portion 101 of panel 1 compresses the watertight rubber member 24, thereby compressing the entire panel 1, which has been compressed vertically by the first compression mechanism 7, toward the interior. At this time, the door stop 4 provided on the outdoor side portion 100 of panel 1 is located outside the pressed surface 100A, so the horizontal pressing member 23 does not press against the door stop 4, and the door stop 4 does not affect the horizontal compression operation.

[0045] When the shutter curtain is compressed in this way (both vertical and horizontal compression), the space between the upper and lower panels is sealed in a watertight manner, and a watertight line is formed by the watertight rubbers 13 and 24 on three sides of the fully closed panel shutter (both ends in the width direction of the shutter curtain located within the left and right guide bodies 2 and the lower end of the shutter curtain) to prevent water from entering the interior space.
