  Here, as shown in FIGS. 5 to 7, the movement restricting body 33 has a shape corresponding to the opening / closing body constituting member 23, and the opening / closing body body 21 of the opening / closing body 16 is the outer peripheral surface of the winding body 8. Is formed into a shape that allows rotation of the other side connection end portion 25 with respect to the one side connection end portion 24 when being wound around.

  The movement restricting body 33 includes a mounting portion 41 fixedly attached to the main body plate portion 26 of one opening / closing body constituting member 23 among the opening / closing body constituting members 23 adjacent to each other by a mounting screw 34, and one side connection end portion. 24 and the other opening / closing member constituting member 23 in the opening / closing member constituting member 23 which is fitted in the notch 40 formed in the other side connecting end portion 25 and is adjacent to each other, is moved laterally (that is, the left side) And a movement restricting portion 42 that restricts the rightward movement and the rightward movement).

  The attachment portion 41 has a substantially rectangular shape that is slightly elongated in the left-right direction in front view (front view), and is formed in a thick plate shape having a predetermined thickness dimension that is thicker than the opening / closing member constituting member 23. A screw hole portion 43 into which a mounting screw 34 is screwed is formed so as to penetrate the front and rear surfaces of the mounting portion 41 at the center in the left-right direction and at both ends in the left-right direction.

  The front surface (for example, one surface, that is, the surface opposite to the opening / closing member constituting member 23 side) of the mounting portion 41 is configured by a first surface 46, a second surface 47, and a third surface 48 that are sequentially located from the top. Has been. The first surface 46 and the third surface 48 are located in an inclined shape gradually moving forward from the upper end toward the lower end, and the second surface 47 is located vertically between the first surface 46 and the third surface 48. .

  The rear surface of the mounting portion 41 (for example, the other surface, that is, the surface on the opening / closing member constituting member 23 side) is configured by a first surface (mounting surface) 51 and a second surface 52 that are sequentially located from the top. The first surface 51 is positioned vertically, and the second surface 52 is a surface parallel to the first surface 46 and the third surface 48 of the front surface, and is gradually inclined forward from the upper end to the lower end. Then, the mounting screw 34 is screwed into the mounting hole 26a of the main body plate portion 26 of the one opening / closing member constituting member 23 and the screw hole portion 43 of the mounting portion 41, whereby the first surface on the rear surface of the mounting portion 41 is obtained. 51 is fixedly attached to the front surface of the main body plate portion 26 in a state of being in surface contact.

  The movement restricting portion 42 is integrally provided so as to protrude obliquely downward and forward in the center portion in the left-right direction of the horizontal lower surface of the mounting portion 41. Then, the left and right side portions of the lower surface of the mounting portion 41 where the movement restricting portion 42 is not provided are in surface contact with the placement portion 24a of the one side connecting end portion 24 of the one opening / closing member constituting member 23. A planar placement portion 55 is placed as a state. For this reason, the attaching part 41 is attached to the main body plate part 26 of the one opening / closing member constituting member 23 in a state where the pair of left and right placing parts 55 are placed and positioned on the placed part 24a.

  The movement restricting portion 42 has a substantially rectangular shape that is slightly elongated in the vertical direction when viewed from the front (front view). Like the mounting portion 41, the movement restricting portion 42 is a thick plate having a predetermined thickness dimension that is thicker than the opening / closing member constituting member 23. Is formed.

  The front surface (for example, one surface, that is, the surface opposite to the opening / closing member constituting member 23 side) of the movement restricting portion 42 is configured by a first surface 56 and a second surface 57 that are sequentially located from the top. The first surface 56 is gradually inclined forward from the upper end to the lower end so as to be continuously located on the same surface as the third surface 48 of the front surface of the mounting portion 41, and the second surface 57 is the upper end. It is located in an inclined shape gradually toward the rear as it goes to the lower end.

  The rear surface (for example, the other surface, that is, the surface on the opening / closing member constituting member 23 side) of the movement restricting portion 42 is configured by only the first surface 60. The first surface 60 is located in an inclined shape that gradually moves forward from the upper end to the lower end so as to be continuously located on the same surface as the second surface 52 of the rear surface of the mounting portion 41.

  Further, the side movement restricting body 31 has a shape corresponding to the opening / closing body constituting member 23 as shown in FIGS.

  The lateral movement restricting body 31 includes a substantially rectangular and flat mounting plate portion 61 fixedly attached to the left and right end portions of the main body plate portion 26 of the opening / closing body constituent member 23 with mounting screws 32, and the mounting plate 61. An outward movement of the opening / closing member constituting member 23 with respect to the suspension member 20 by contact (hooking) with the side end surface 8a which is integrally provided at the end of the plate portion 61 by bending and which is the axial end surface of the winding body 8 And a substantially rectangular movement restricting plate 62 for restricting the movement. A plurality (for example, three) of screw hole portions 63 are formed in the mounting plate portion 61 so as to penetrate the front and rear surfaces.

  Then, the mounting screw 32 is screwed into the mounting hole (not shown) of the main body plate portion 26 of the opening / closing member constituting member 23 and the screw hole portion 63 of the mounting plate portion 61, whereby the rear surface of the mounting plate portion 61. Is fixedly attached to the front surface of the main body plate portion 26 in a state of being in surface contact.

  In addition, the angle θ formed by the mounting plate portion 61 and the movement restricting plate portion 62 shown in FIG. 9 is, for example, 100 degrees. Therefore, as shown in FIG. 4, even when the winding body 8 is bent by the weight of the opening / closing body 16, the movement restricting plate portion 62 does not hit the outer peripheral surface of the winding body 8, and the opening / closing body 16 is appropriately wound around the outer peripheral surface of the wound body 8.

  Next, the operation and the like of the opening / closing device 1 will be described.

  First, attachment work of the side movement restricting body 31 and the movement restricting body 33 will be described.

  For example, when the normal opening / closing device 1 is shipped from a factory, the side movement restricting body 31 and the movement restricting body 33 are not attached to the opening / closing body 16. In addition, you may make it attach the regulation bodies 31 and 33 beforehand at a factory.

  Then, after the opening / closing device 1 is installed at the construction site, if the opening / closing operation of the opening / closing member 16 is repeated due to the long-term use of the opening / closing device 1, the second opening / closing member constituting member 23 based on the bending of the winding body 8 or the like. Is moved sideways to the first roll opening / closing member constituting member 23 due to the fact that a horizontal component is generated by contacting the first winding opening / closing member constituting member 23 only on either one of the left and right sides ( A lateral flow) may occur, and there may be a problem that the left and right ends of the first roll opening / closing member constituting member 23 come into contact with the bracket 10 of the container 7.

  In such a case, the operator retrofits the opening / closing body 16 with the lateral movement restricting body 31 and the movement restricting body 33 that prevent the occurrence of the lateral flow at the construction site.

  That is, for example, the operator rewinds the opening / closing body 16 from the winding body 8 to the maximum extent until the main body plate portions 26 of the plurality of, for example, five opening / closing body constituting members 23 of the first roll are positioned vertically. After that, for example, an inspection opening (not shown) of the container 7 is opened, and the attaching work of the regulating bodies 31 and 33 is performed. At this time, the ceiling at the construction site is not required to be suspended or to take out the winding body 8 from the housing 7.

  Specifically, the worker attaches the lateral movement restricting body 31 to both ends in the left-right direction of the main body plate portion 26 of the first opening / closing body constituting member 23.

  That is, after the mounting holes are formed in the left and right ends of the main body plate portion 26 of the first opening / closing member constituting member 23, the mounting screws 32 are attached to the mounting holes and the mounting plate of the main body plate portion 26 from the outdoor side, for example. The state in which the rear surface of the mounting plate portion 61 is brought into contact with the front surface of the main body plate portion 26 (the surface on the side facing the outer peripheral surface of the winding body 8) by being screwed into the screw hole portion 63 of the portion 61. As fixed.

  The operator attaches the movement restricting body 33 to each main body plate portion 26 of the first to fifth opening / closing member constituting members 23.

  That is, first, the worker cuts and removes a part of the arbitrary position in the left-right direction of the opening / closing member constituting member 23 in the state shown in FIG. A notch 40 is formed in one side connecting end 24 and the other side connecting end 25 which are connected to each other so as to be rotatable.

  The length dimension of the notch 40 in the left-right direction is substantially the same as the length dimension of the movement restricting portion 42 in the left-right direction. The lateral length of the notch 40 may be smaller than the lateral length of the movement restricting portion 42, and the movement restricting portion 42 may be inserted into the notched portion 40. The length dimension in the left-right direction of the portion 40 may be slightly larger than the length dimension in the left-right direction of the movement restricting portion 42, and the movement restricting portion 42 may be fitted into the notch 40 in a loosely fitted state. In this case, the lateral movement of the opening / closing member constituting member 23 is allowed slightly, but there is no problem as long as it is within a range not contacting the bracket 10.

  Next, as shown in FIG. 13, the operator inserts the movement restricting portion 42 into the cutout portion 40 from the upper side, for example, and places the left and right placement portions 55 on the placement portion 24 a of the one side connection end portion 24. Place. Thus, the movement restricting body 33 is positioned at a desired position with respect to the opening / closing body constituting member 23 to be attached.

  Subsequently, the operator forms the mounting hole 26a at a position corresponding to the screw hole portion 43 of the mounting portion 41 in the main body plate portion 26 of the opening / closing member constituting member 23, and then attaches the mounting screw 34 from the outdoor side, for example. By screwing into the mounting hole 26a of the main body plate portion 26 and the screw hole portion 43 of the mounting portion 41, the first surface 51 on the rear surface of the mounting portion 41 is connected to the front surface of the main body plate portion 26 (the outer peripheral surface of the winding body 8). It is fixedly attached in a state where it is brought into contact with the surface).

  In this state, as shown in FIG. 1, the left and right side surfaces of the movement restricting portion 42 are in contact with (including substantially contacting with) the side end surfaces of the connecting end portions 24 and 25 facing the notch portion 40. In addition, the first surface 60 on the rear surface of the movement restricting portion 42 is opposed to the upper end surface of the other side connecting end portion 25 facing the notch portion 40 through the rotation allowing gap 39.

  Since the rotation-allowing gap 39 allows the one-side connection end 24 to rotate with respect to the other-side connection end 25, even if the movement restricting body 33 is attached, it is the same as before the attachment. The opening / closing member constituting member 23 is wound around the outer peripheral surface of the winding body 8.

  Further, the leftward movement and the rightward movement of the opening / closing member constituting member 23 are restricted by the movement restricting plate portion 62 of the lateral movement restricting body 31 and the movement restricting portion 42 of the movement restricting body 33 on both the left and right sides.

  According to such an opening / closing device 1, the side movement restricting body 31 and the movement restricting body 33 can be easily attached on the construction site, and the attached side movement restricting body 31 and the movement restricting body 33 are attached to the attached side movement restricting body 31 and the movement restricting body 33. Thus, the lateral movement of the opening / closing member constituting member 33 of the first roll can be appropriately restricted, so that it is possible to effectively prevent the occurrence of the problem that the left and right end portions of the opening / closing member constituting member 23 are in contact with the bracket 10.

  Further, the movement restricting body 33 includes a placement portion 55 placed on the placement portion 24a of the one side connection end portion 24, and the mounting portion 41 is placed on the placement portion 24a. Since it can be attached to the opening / closing member constituting member 23 in a state, the attaching operation is further facilitated.

  Furthermore, since the attachment portion 41 of the movement restricting body 33 has a screw hole portion 43 into which the attachment screw 34 is screwed, the attachment portion 41 can be attached easily and appropriately using the attachment screw 34.

  Further, the movement restricting body 33 is formed in a shape that allows the other side connecting end 25 to rotate with respect to the one side connecting end 24 when the opening / closing body 16 is wound around the outer peripheral surface of the winding body 8. Therefore, the movement restricting body 33 does not hinder the rotation of the other side connection end portion 25, and the winding body 8 can appropriately wind the opening / closing body 16.

  Note that the movement restricting body 33 is not limited to one integrally formed of, for example, a metal material or a resin material. For example, as shown in FIG. It may be composed of one member 71 and a thick plate-like second member 72.

  The first member 71 has a first plate portion 73 that is slightly elongated in the left-right direction when viewed from the front (front view), and a diagonally downward front from the center in the left-right direction at the lower end of the first plate portion 73.

The rear surface of the attachment portion 41 is configured by a first surface (attachment surface) 83, a second surface 84, and a third surface 85 that are sequentially located from the top. The first surface 83 is positioned vertically, the second surface 84 is positioned inclined gradually toward the front from the upper end to the lower end, and the third surface 85 is positioned vertically.

  Further, the front surface of the movement restricting portion 42 of the movement restricting body 33 is constituted by only the first surface 86, and the first surface 86 is continuously located on the same surface as the second surface 82 of the front surface of the mounting portion 41. So that it is vertically positioned. The rear surface of the movement restricting portion 42 is constituted by only the first surface 87, and the first surface 87 is vertically positioned so as to be continuously located on the same surface as the third surface 85 of the rear surface of the mounting portion 41. . The lower surface of the movement restricting portion 42 is opposed to the upper end surface of the other side connecting end portion 25 facing the notch portion 40 through the rotation allowing gap 39.

  The side movement restricting body 31 having the shape shown in FIGS. 21 to 23 has a slightly shorter vertical dimension than the side movement restricting body 31 having the shape shown in FIGS.

  For example, in the case of the opening / closing member constituting member 23 having the shape shown in FIGS. 24 and 25, the movement restricting body 33 having the shape shown in FIGS. 26 to 28 is used, and the lateral movement having the shape shown in FIGS. 29 to 31 is used. A regulator 31 is used. And when these control bodies 31 and 33 are used, there can exist an effect similar to the said embodiment.

  The front surface of the mounting portion 41 of the movement restricting body 33 having the shape shown in FIGS. 26 to 28 is composed of a first surface 91 and a second surface 92 that are sequentially located from the top. The first surface 91 is positioned vertically, and the second surface 92 is positioned in an inclined shape that gradually moves forward as it goes from the upper end to the lower end. The rear surface of the attachment portion 41 is configured by a first surface (attachment surface) 93 and a second surface 94 which are sequentially located from the top. The first surface 93 is positioned so as to gradually move backward as it goes from the upper end to the lower end, and the second surface 94 is positioned so as to gradually move forward as it goes from the upper end to the lower end.

  In addition, the front surface of the movement restricting portion 42 of the movement restricting body 33 is constituted only by the first surface 96, and the first surface 96 is positioned vertically. The rear surface of the movement restricting portion 42 is composed of a first surface 97 and a second surface 98 that are positioned in order from the top. The first surface 97 is positioned in a vertical shape, and the second surface 98 is positioned in an inclined shape that gradually moves forward as it goes from the upper end to the lower end. The lower surface of the movement restricting portion 42 is opposed to the upper end surface of the other side connecting end portion 25 facing the notch portion 40 through the rotation allowing gap 39.

  In the lateral movement restricting body 31 having the shape shown in FIGS. 29 to 31, the mounting plate portion 61 is bent in a substantially square shape, and the movement restricting plate portion 62 is formed in a bifurcated shape. That is, the movement restricting plate 62 is configured by the plate portions 102 that are spaced apart from each other with the gap 101 therebetween.

  Note that the movement restricting body 33 shown in FIG. 18 and the movement restricting body 33 shown in FIG. 26 are not limited to one member, and the thickness of the thin plate-like first member and the thickness is reduced in order to reduce manufacturing costs. You may make it comprise with a plate-shaped 2nd member (refer FIG. 14, FIG. 15).

  The regulating bodies 31 and 33 can be attached to any open / close body constituting member 23 constituting the open / close body main body 21 of the open / close body 16 and can be attached only to the open / close body constituting member 23 in which a lateral flow has occurred, or a lateral flow has occurred. The opening / closing member constituting member 23 and the opening / closing member constituting member 23 adjacent to the opening / closing member constituting member 23 may be attached, or may be attached to other than the first roll.

  Furthermore, the movement restricting body 33 may be attached to the suspension member 20, and the movement restricting body 33 may restrict the lateral movement of the first opening / closing member constituting member 23 relative to the suspension member 20.

  Moreover, although the case where both the side movement restricting body 31 and the movement restricting body 33 are used has been described, for example, a configuration using only the movement restricting body 33 may be used.

  Further, the notch 40 may be formed in advance at a manufacturing plant, for example, so that it is not necessary to form the notch 40 at the construction site.

  Further, a caulking portion and a cutout for preventing a lateral flow may be formed at the end in the left-right direction of the opening / closing body constituting member 23, and when the caulking portion is broken, the opening / closing body constituting member is used instead of the caulking portion. A substantially L-shaped movement restricting body 33 that is partly cut and removed so as not to protrude from the side end of 23 may be attached to the left and right end portions of the opening / closing body constituting member 23.

  Furthermore, the opening / closing device 1 is not limited to a shutter device such as a heavy shutter fixed around the opening 2 of the building. For example, although not shown, other shutter devices fixed around the other opening A blind device or the like, or a device in which a plurality of the same or different types of these devices are arranged in parallel may be used.

  Further, the number of the opening / closing member constituting member (slat) 23 to which the movement restricting member (intermediate hook) 33 is attached is arbitrary.

  Further, the position of the opening / closing member constituting member 23 to which the movement restricting body 33 is attached is preferably an end, but is arbitrary. In the case of the end portion, the opening / closing member constituting member 23 is preferably provided on the side in which it flows laterally. In the case of the end portion, if there is no hindrance to the opening / closing movement of the opening / closing member constituting member 23, the whole or a part of the movement restricting body 33, and further all or a part of the plurality of movement restricting bodies 33 are inserted into the guide groove portion 4. May be.

  Further, the head 35 of the mounting means such as the mounting screws 32 and 34 does not protrude from the slat surface, that is, the surface of the opening / closing member constituting member 23 (for example, the surface facing the outdoor side or the surface facing the indoor side). In addition, a recess into which the head 35 is inserted may be provided on the surface of the opening / closing member constituting member 23. In other words, the attachment means may be prevented from protruding on the slat surface opposite to the side on which the movement restricting body 33 is attached.

  Furthermore, the shape and attachment method of the movement restricting body 33 are arbitrary as long as the connection end portions 24 and 25 can be rotated. That is, for example, the positional relationship between the attachment portion 41 and the movement restricting portion 42 may be reversed upside down from FIG. 13, and the attachment portion 41 may be attached to the lower opening / closing member constituting member 23. Alternatively, the movement restricting body 33 may include two attachment portions 41, and the two attachment portions 41 may be attached to the opening / closing body constituting members 23 adjacent to each other. In this case, the movement restricting body 33 needs to be formed of a member such as a spring steel material having some stretchability and flexibility.

  Further, in the first roll of the opening / closing body 16, it is the curled portion of the opening / closing body constituting member 23 that comes into contact with the winding body 8, and the movement restricting body 33 only contacts at most the winding body 8 (in other words, The curling portion does not protrude so as not to come into contact with the winding body 8, and does not abut against the winding body 8. The body 33 is attached. However, the present invention is not limited to this case, and may be configured as follows.

  That is, for example, the movement restricting body 33 may be attached not only to the first roll of the opening / closing body 16 but also to the second roll (may be more). In this case, since the curled portion comes into contact with the opening / closing member constituting member 23 instead of the winding body 8, the movement restricting member 33 is preferably configured to be in contact with the opening / closing member constituting member 23 at most.

  Further, for example, the configuration in which the opening / closing member constituting member 23 is wound in the opposite direction to that of FIG. 2 so that the surface (slat surface) of the opening / closing member constituting member 23 contacts the winding body 8 in the first roll. In this case, the movement restricting body 33 comes into contact with the surface of the opening / closing member constituting member 23 (or the curl portion depending on the case) instead of the winding body 8 instead of the winding body 8. A configuration in which the surface (curl portion) of the member 23 is at most in contact is preferable.
