  In this embodiment, in order to improve the slip-out prevention performance, the rail reinforcing member 411 is engaged with the engaging portion 902 of the inner rail 90 and the engaging portion 807 of the outer rail 80, respectively. The reinforcing member 42 is engaged with the engaging portion 903 of the inner rail 90. Since the outer rail 80 and the inner rail 90 are formed by extrusion of aluminum alloy or the like, the mechanical strength is relatively weak, and the opening groove 801 may be easily deformed by a bar or the like. Therefore, steel rail reinforcing members 411 and 42 having high mechanical strength are provided between the outer rail 80 and the inner rail 90 to reinforce the mechanical strength.

  The rail reinforcing member 411 has a shape in which both sides are bent perpendicularly in opposite directions, one of the bent portions on both sides engages with the engaging portion 902 of the inner rail 90, and the other on the inner wall surface of the outer rail 80.

The portions of the rail reinforcing members 411 and 42 that are in contact with the inner wall surface of the outer rail 80 are fixed to the outer rail 80 with a fixing tool such as a screw. At this time, it is preferable that fixing tools such as screws and rivets are arranged in a staggered manner along the longitudinal direction of the outer rail 80. As described above, the provision of the rail reinforcing members 411 and 42 improves the mechanical strength of the guide groove 906 of the inner rail 90. Therefore, even if the opening groove 801 is easily deformed by a bar or the like, the inner rail 90 The guide groove 906 is prevented from being easily deformed, and it is possible to effectively prevent the retaining claws 11a provided on both side edges of the slat 11 of the shutter curtain 12 from coming out of the guide groove 906. The inner rail 90 may be made of the same steel as the rail reinforcing members 411 and 42. Further, the hollow portion formed inside the outer rail 80 in FIG. 8 may be used as a space for wiring and the like.

  FIG. 10 is a diagram showing a detailed configuration of a seat plate portion serving as a closed end portion of the shutter curtain, and FIG. 10A is an enlarged view of a right side portion of the closed end portion of the shutter curtain of FIG. FIG. 10B is a side view of FIG. 10A viewed from the right side. The seat plate portion 121 is provided at a lower portion on the closed front end side of the shutter curtain 12 and includes a seat plate switch for detecting an obstacle.

As shown in FIG. 10A, the hook 110 has a convex shape having a retaining claw 11 a at the center, and the bottom side of the convex portion is joined along the shape of the slat 11. The connection between the slat 11 and the seat plate portion 121 is provided with a question bar 105 whose overall shape is substantially “?”.

  11 is a diagram showing a detailed configuration of the question bar 105 in FIG. 10, FIG. 11A is a diagram showing an overall configuration of the question bar 105, and FIG. 11B is a diagram showing the slat 11 and the question bar 105. It is a figure which expands and shows a connection part. As shown in FIG. 11A, the upper seat plate 100 of the seat plate portion 121 is fixed to a plate member 1051 extending downward by a fixing tool such as a screw. On both sides of the question bar 105, there are slat holding portions 1052, 1053 that are bent so that their base end portions protrude in a direction substantially perpendicular to the plate member 1051 and the tip ends are substantially parallel to the plate member 1051. That is, as shown in FIG. 11, the shape of the portion in contact with the slat 11 on the upper side of the slat holding portions 1052 and 1053 is formed so as to substantially match the shape of the lower side of the slat 11. Accordingly, when the slat 11 is lowered and contacts the question bar 105, the relative positional relationship between the slat 11 and the question bar 105 is always maintained in the same state, and the slat 11 and the question bar 105 are shaken. When the movement is restricted and the shutter curtain 12 is in contact with the floor surface and closed, a stable closed state can be maintained. Further, since the shape of the question bar 105 is a shape that considers a good engagement state with the slat 11, it is possible to improve airtightness such as waterproof and dustproof between the slat 11 and the question bar 105. .

  12 is a diagram showing a detailed configuration of the seat plate guide 106 of FIG. 10, FIG. 12 (A) shows a perspective view of the seat plate guide, and FIG. 12 (B) is a front view of FIG. 12 (A). 12C is a top view of FIG. 12B, and FIG. 12C is a side view of FIG. 12B viewed from the left side. The slat 11 is provided with a retaining claw 11 a that moves along the inner rails 40 and 90 of the guide rail 13. Thereby, the slat 11 at the time of raising and lowering can stably move along the guide rail 13. Since there is no such a retaining claw in the seat plate portion 121, a seat plate guide 106 is provided so as to stabilize the movement when ascending and descending. The seat plate guide 106 has a shape as shown in FIG. 12 and is movable along the guide rail 13. As a result, when the seat plate portion 121 is raised and lowered, the seat plate portion 121 is stably raised and lowered.

  FIG. 13 is a diagram showing details of a suspension source for attaching the shutter curtain to the winding shaft. The suspension source is a member that is connected to the winding shaft at the top of the slat. FIG. 13A is a diagram showing a detailed configuration of a conventional standard suspension source, and FIG. 13B is a diagram showing a detailed configuration of the suspension source with improved crime prevention according to this embodiment. Yes, FIG. 13C is a diagram showing another example of a suspension source with improved crime prevention according to this embodiment. As shown in FIG. 13A, the standard suspension base 21 includes a flat portion 211 fixed to a winding shaft with a fastener such as a screw or a bolt, and a “height” formed on the right side of the flat portion 211. ”And a connecting curl portion 213 engaged with the connecting curl portion of the slat 11 formed on the left side of the flat portion 211. As shown in FIG. 13 (A), in the conventional standard suspension base 21, the connecting curl portion 213 has the same shape as the connecting curl portion of the slat, so that the slat can be freely set via this engaging portion. It is designed to rotate. Therefore, when the shutter curtain 12 is fully closed as shown in FIG. 6 and the rotation of the winding shaft is braked by a brake device of a motor opening / closing device, for example, when the shutter curtain 12 is lifted, By freely rotating and moving the engaging part of the suspension source, the slat is rotated relative to the suspension source, and the slat is loosened in the space between the upper end portion of the guide rail, the winding shaft, and the inner wall portion of the shutter case 1. There is a possibility that the lower part which is the closed front end side of the shutter curtain 12 which is in the fully closed state is slightly opened.

  Therefore, as shown in FIG. 13B, the length of the curled portion 223 of the suspension base 22 is increased so that the slat engaged with the curled portion 223 does not freely rotate. As shown in FIG. 13C, the length of the curled portion 233 of the suspension base 23 may be further increased.

Also in FIG. 32, illustration is abbreviate | omitted using the omission line similarly. In FIG. 32, buffer rubbers 321 to 32c are arranged at both end portions of the slat 11, respectively. This is due to the contact between the slat that is the inner layer when winding and unwinding the shutter curtain and the slat that is wound around the outer layer and the slat that is the outer layer, contact with the edges of the left and right guide rails during opening and closing movement, Is installed in order to suppress the generation of abnormal noise and wear as much as possible due to contact with the guide rail due to flutter when wind pressure or the like is applied to the shutter curtain when closed. In the figure, a case where a cushioning rubber is provided for every other slat is shown, but a plurality of cushioning rubbers may be provided for each slat or for each slat. Since the slats 11 are made of foamed urethane-filled aluminum forming slats, the buffer rubber is fitted and fixed by a fixing tool such as a screw or a rivet (see FIG. 33B). When the buffer rubber is fixed to the slat 11, the buffer rubber may be attached as the same part shape as the wind-resistant claws provided at both end portions of the slat 11. In this case, special processing for installing the shock absorbing rubber is not required, and the manufacture becomes easy. In addition, in the figure, the case where a buffer rubber and a wind-resistant nail | claw are arrange | positioned alternately is shown. Moreover, although the shock absorbing rubber is provided on one side of the slat, it may be provided on both sides or any one side. In addition to the effect that noise and wear can be suppressed by providing the cushioning rubber so that the gap between the guide rail and the slat can be closed when the shutter curtain is provided on the shutter curtain, a bar or the like guides the guide.

Also in FIG. 34, the illustration is omitted using the omission line. In the above-described embodiment, when the shutter curtain is wound, the wind-resistant claws of the slat hooks of several slats on the inner layer side where the winding diameter of the shutter curtain is small are in contact with each other. The wind-resistant claws of the slat hooks in the slat on the outer layer side just outside may come into contact with each other, causing winding misalignment, noise, and damage. Therefore, in the embodiment of the shutter curtain of FIG. 34, the wind-resistant claw portions of the three slat hooks 341 to 346 on the upper side of the shutter curtain are cut and removed. The wind-resistant claws are removed from several sheets that are wound around the winding shaft first and become the innermost layer side. This is because the first few slats from which windproof claws have been removed are wound around the winding shaft, so that the winding diameter of the shutter curtain wound after that becomes sufficiently large, and the above-mentioned problem of contact It is because it can suppress.

  FIG. 35 is a diagram showing a detailed configuration of the slat hook of FIG. FIG. 35 (A) shows details of the slat hooks 351 to 356 before the wind-resistant claw portion is cut. FIG. 35 (B) shows details of the slat hooks 341 to 346 after the wind-resistant claw portion is cut. FIG. 35C illustrates a top view of FIG. FIG. 35D shows a side view of FIG. FIG. 36 (A) shows a perspective view of the slat hook before the wind-resistant claw portion is cut, and FIG. 36 (B) shows a perspective view of the slat hook after the wind-resistant claw portion is cut. As is clear from the figure, the wind-resistant claw portions are simply removed from the normal slat hooks 351 to 356. As a result, it is not necessary to change the processing of the slat portion of the shutter curtain, and it is possible to cope with the problem caused by the contact when the shutter curtain is wound up in a normal slat hook mounting operation. .

Further, a guide plate 375 curved in an R shape is provided so as to connect the R-shaped portions of the two anti-lift plate materials 372 and 373. Since the surface of the guide plate 375 is curved along the R-shaped portions of the prevention plate members 372 and 373, when the shutter curtain 12 is wound around the take-up shaft and the roll becomes thick, slats are generated. This prevents the lifting prevention plate members 372 and 373 from coming into contact and being damaged. Incidentally, a notch 376 cut out in a rectangular parallelepiped shape is formed on the back surface of the lifting prevention plate means 371 as in the case of FIG.
