However, since the shutter structure of Patent Document 1 uses a resin retaining piece, it can cope with a noise caused by contact with the guide rail during the lifting operation, but the strength as a retaining member may be insufficient. There is. For this reason, there is a risk of falling off the slats with a strong force of strong wind. In addition, the resin retaining piece is damaged due to wear and is inferior in durability.
Moreover, although the edge part metal structure of the shutter of patent document 2 is fixed to a slat by welding, positioning is complicated and it is difficult to align at a fixed attachment position with respect to all the slats. In addition, the end of the curled part (connecting part) is formed with a notch on one side and a notch on the other side to prevent misalignment of the connecting slats. After connecting the slats, the other side is crimped and deformed. The structure is such that the end face of the caulking portion is disposed opposite to the end face of the notch so as to prevent each other from coming off. For this reason, the deformed caulking portion or the cut portion may be in sliding contact with the silencer band of the guide rail, and the silencer band may be scraped off by this sliding contact. In order to reduce this shaving, it may be necessary to remove burrs using a router or the like.

For this reason, compared with the conventional metal retaining part, the slidability with the guide rail 13 is improved, and it is difficult for noise to occur during sliding contact with the guide rail 13. Further, the lateral displacement of the slat 19 is prevented by the restriction piece 45 formed on the metal plate portion 21 of the wind-resistant hook 15. For this reason, compared with the conventional resin-made regulation piece, the lateral slip prevention strength can be increased. In addition, as in the conventional structure for preventing lateral displacement due to the metal caulking portion, the caulking portion and the cut portion for forming the caulking portion do not slide in contact with the silencing zone 55 of the guide rail 13 and the silencing zone 55 is not damaged. In addition, since the caulking portion is abolished, it is difficult to generate a sound due to the caulking portion contacting the guide rail 13. Furthermore, since the retaining portion 37 is made of the resin portion 33, when the guide rail 13 is made of aluminum, the wear of the guide rail 13 can be suppressed as compared with the conventional retaining portion 37 made of metal. Further, since the metal caulking portion is abolished, complicated shape processing of the slat 19 and complicated caulking processing are eliminated, and easy manufacture is possible. Furthermore, since the wind-resistant hook 15 can be assembled simply by fixing it to the slat 19 with a fixing member, the processing and assembly man-hours can be greatly reduced as compared with the conventional structure for preventing lateral displacement by caulking.

As a result, the upper engagement connection portion 23 and the lower engagement connection portion 25 become the upper and lower engagement connection portions 27 engaged over the substantially horizontal longitudinal direction of the slat 19. The slat curtain 11 connects the plurality of slats 19 so that they can be bent in the vertical direction with the upper and lower engagement connecting portions 27 as joints.

  In the present embodiment, wind resistant hooks 15 are fixed to slat curtains 11 at every other slat 19 as shown in FIG. The wind-resistant hook 15 is fixed to the end portions 17 on both sides in the longitudinal direction of the slat 19 by rivets 29 or the like as fixing members. Therefore, a slat hole 31 into which the rivet 29 or the like is inserted is formed at a predetermined position in the end portion 17 of the slat 19 with high accuracy using a jig or the like.

  The wind-resistant hook 15 is integrally formed with the resin portion 33 (see FIGS. 5 and 8) covering a part of the metal plate portion 21. That is, a hybrid structure in which a resin and a metal are joined together is obtained. Integration of the resin part 33 and the metal plate part 21 can be performed by insert molding, for example. The resin portion 33 is made of, for example, polycarbonate, vinyl chloride resin, polyethylene, ABS resin, or the like. The metal plate part 21 consists of steel plates, such as SPCC, for example. The wind-resistant hook 15 has a main body piece portion 35 fixed to the end portion 17 of the slat 19 so as to be substantially the same thickness as the thickness of the slat 19, that is, the entire thickness of the slat 19 including the upper and lower engagement connecting portions 23 and 25. Have. The main body piece portion 35 is formed of a thin hexahedron having a substantially square shape when viewed from the front.

  As shown in FIG. 6, a retaining portion 37 that protrudes from the end portion 17 of the slat 19 and has a bulging tip is formed by the resin portion 33 on one side of the main body piece portion 35. As shown in FIG. 4, the retaining portion 37 includes a wind-resistant claw portion 39 having a T-shaped tip in plan view. The windproof claw portion 39 is connected to the main body piece portion 35 by the neck portion 41.

  On the metal plate portion 21 of the wind-resistant hook 15, a restriction piece 45 is formed to extend so as to block the end surface 43 of the upper and lower engagement connecting portion 27 of the slat 19 and prevent sliding movement between the slats 19. In the present embodiment, the restriction pieces 45 are projected in pairs from each of a pair of parallel sides sandwiching the retaining portion 37 of the main body piece portion 35. As shown in FIG. 3, the pair of restricting pieces 45 are formed in a wing shape extending from the main body piece portion 35 and inclined to a C-shape bent toward one surface side of the slat 19. Due to this inclination, the restricting piece 45 does not protrude outward from the circumference when the slat curtain 11 is in the wound state shown in FIG.

  As shown in FIG. 4, the guide rail 13 is fixed to the building side along both side edges of the slat curtain 11. The guide rail 13 guides the slat curtain 11 up and down by inserting the retaining portion 37 of the wind-resistant hook 15 so as not to be removable. In the guide rail 13, a vertical slit 49 is formed in a rectangular tube portion 47 extending in the vertical direction. The wind-resistant claw portion 39 is configured such that the neck portion 41 is disposed in the slit 49 and the wind-resistant claw portion 39 is disposed on the inner side of the rectangular tube portion 47, thereby restricting the slat 19 from being removed from the rectangular tube portion 47.

  The guide rail 13 is provided with a guide rail case 51 that covers the rectangular tube portion 47. In the guide rail case 51, curtain moving openings 53 are formed along the slits 49 so as to arrange both side edges of the slat curtain 11. A pair of sound deadening bands 55 in contact with the front and back of the slat curtain 11 are attached to the curtain moving opening 53. In the shutter curtain structure, the lateral movement of the upper and lower slits 49 connected by the upper and lower engagement connecting portion 27 is restricted by the restriction piece 45 of the wind-resistant hook 15. For this reason, it is not necessary to form a caulking portion in the vertical engagement coupling portion 27 as in the conventional structure. As a result, the muffler band 55 is in contact with the smooth front and back surfaces of the slat curtain 11 where the crimped portion is not provided, and therefore can be prevented from being damaged by contact with the crimped portion.

  A notch recess 57 shown in FIG. 9 is formed in the metal plate portion 21 of the wind-resistant hook 15. The notch recess 57 is formed in a substantially C-shape having a deepened shape embedded in the resin portion 33 as shown by a broken line in FIG. 7 at an edge portion 59 on one end side of the metal plate portion facing the retaining portion 37. . In the cutout recess 57, the narrow portion 61 on the open side becomes the retaining portion side. The resin portion 33 filled in the notch recess 57 is formed by connecting to the retaining portion 37 via the narrow portion 61. That is, the resin portion 33 in the notch recess and the resin portion 33 of the retaining portion 37 are integrally formed. Thereby, the force in the pulling direction from the main body piece portion 35 acting on the retaining portion 37 is supported by the pair of narrow portions 61 that bite in opposite directions from both sides of the main body piece portion 35.

  Further, as shown in FIG. 9, the metal plate portion 21 extends over at least one of the front and back surfaces of the metal plate portion to the notch recess 57 and the other end 63 of the metal plate portion on the opposite side of the notch recess 57. A groove-like recess 65 extending in the direction is formed. The groove-shaped recess 65 is formed along the flow direction of the molten resin during molding. Thereby, the molten resin at the time of shaping | molding becomes easy to flow, and favorable moldability is obtained now. The groove-like recess 65 may have a serrated jagged or uneven shape in addition to the curved groove shape shown in FIG. 9B. Thereby, the joint strength of the metal plate part 21 and the resin part 33 can be raised, and it can prevent peeling easily.

  Further, the metal plate portion 21 is provided with an embedded through hole 67 through which the resin portion 33 is formed. The resin portion 33 is formed through the embedded through hole 67. That is, the resin part 33 covering the metal plate part front and back surfaces with the metal plate part 21 sandwiched between the front and back surfaces is formed by the columnar resin part 69 (see FIG. 8) that is to be formed through the embedded through hole 67. It is formed so as to be connected, and is integrally connected and fixed. In addition, this embedding penetration part 67 is arrange | positioned and formed in the approximate center in the position where the above-mentioned groove-shaped recessed part 65 is formed, From this, it becomes easy to flow in the molten resin at the time of shaping | molding, and the columnar resin part 69 The groove-shaped recess 65 is also effective for the formation of.

  The main body piece portion 35 is formed with a fixing hole 71 that penetrates the resin portion 33 and the metal plate portion 21 and is fixed to the end portion 17 of the slat 19 by a rivet 29 or the like. In the main body piece portion 35, the metal plate portion 21 and the resin portion 33 are stacked in a stacked manner, and in the present embodiment, the resin portion 33 is sandwiched and covered from the front and back by the metal plate portion 21. The fixing hole 71 is drilled through the resin part 33 and the metal plate part 21 to be laminated. Note that the inner periphery of the fixing hole 71 may be covered with resin during molding. The fixing hole 71 is inserted with a rivet 29, a screw, a bolt, or the like as a fixing member. The rivet 29 or the like inserted through the fixing hole 71 is fixed to the slat hole 31 that is previously drilled in the end portion 17 of the slat 19.

  The metal plate portion 21 is formed into a predetermined shape, and after being placed at a predetermined position of a molding die (not shown), a molten resin is injected into the molding die to be insert-molded. 33 is formed integrally so as to cover a part of the metal plate portion 21. The metal plate portion 21 having the restricting piece 45, the notch recess 57, the groove-like recess 65, the embedded through hole 67, the fixing hole 71 and the like can be formed by punch pressing (punching) or bending. it can. In addition, the metal plate portion 21 may be bent by forming an outer shape without performing punching by using a laser processing machine. Further, the metal plate portion 21 may be formed by performing punching and bending simultaneously by punch press processing.

Next, the operation of the structure of the shutter curtain having the above configuration will be described.
In the shutter curtain structure according to the present embodiment, the retaining portion 37 made of the resin portion 33 of the wind-resistant hook 15 is engaged with the guide rail 13. For this reason, compared with the conventional metal retaining part (hook part), the slidability with the guide rail 13 is improved, and it is difficult to generate noise.
Further, the lateral displacement of the slat 19 is prevented by the restriction piece 45 formed on the metal plate portion 21 of the wind-resistant hook 15. For this reason, compared with the conventional resin-made regulation piece, the lateral slip prevention strength can be increased.

  Further, like the conventional structure for preventing lateral displacement by the metal caulking portion, the caulking portion can be prevented from sliding on the silencing zone 55 of the guide rail 13 and damaging the silencing zone 55.

  In the shutter curtain structure, the caulking portion is abolished, so that it is possible to prevent noise due to the caulking portion coming into contact with the guide rail 13. Further, since the retaining portion 37 is made of the resin portion 33, even when the guide rail 13 is made of aluminum, wear of the guide rail 13 can be suppressed as compared with a conventional metallic retaining portion (hook portion). .

  In addition, since the metal caulking portion and the cut portion for forming the metal caulking portion are eliminated, complicated shape processing and complicated caulking processing of the slat 19 are eliminated, and the slat curtain 11 can be easily manufactured.

  Furthermore, since the wind-resistant hook 15 can be assembled simply by fixing it to the slat 19 with a rivet 29 or the like, the machining and assembly man-hours can be greatly reduced compared to the conventional structure for preventing lateral displacement by caulking. For example, as shown in FIG. 6, the wind-resistant hook 15 is fixed to one end of the slat 19 in advance with a rivet 29 or the like, and the other slat 19 can be slid and engaged from the other end side. By fixing the wind-resistant hook 15 to the other end of the slat 19 without processing or the like, the prevention of the lateral displacement between the slats 19 can be completed, and the slats 19 can be connected.

  Further, in this shutter curtain structure, when wind pressure acts on the slat curtain 11, the slat 19 is pinched and bent, whereby a force in the direction of being pulled out from the guide rail 13 acts on the end portion 17 of the slat 19. This pull-out force is supported by a retaining portion 37 of the wind-resistant hook 15 fixed to the end portion 17. The retaining portion 37 is formed by the resin portion 33 integrated with the main body piece portion 35. The resin portion 33 integrated with the retaining portion 37 is molded with an engagement structure, that is, a structure that supports a slipping load, in a notch recess 57 made of metal. The retaining portion 37 is supported by a narrow portion 61 having a depth-expanding shape in a notch recess 57 formed in the metal plate portion 21 in a direction in which the retaining portion 37 is pulled out from the main body piece portion 35. As a result, the retaining portion 37 can increase the strength in the direction separated from the main body piece portion 35.

  In this shutter curtain structure, at least one of the front and back surfaces of the metal plate part is fixed to the resin part 33 formed by entering the groove-like recess 65 by the engagement structure. As a result, the strength in the direction in which the resin portion 33 and the metal plate portion 21 are separated in the vertical direction can be increased.

  Further, the resin part 33 covering the front and back surfaces of the metal plate part across the metal plate part 21 is integrally connected and fixed by a columnar resin part 69 that penetrates the embedded through hole 67. As a result, the resin and the metal are simply formed in layers, and the resin portion 33 not only covers the metal plate portion 21 but also the adhesion strength of the resin portion 33 to the front and back surfaces of the metal plate portion can be increased.

  Further, the wind-resistant hook 15 attached to the end portion 17 of the slat 19 is fixed by inserting a rivet 29 or the like into a fixing hole 71 formed in the main body piece portion 35 of the wind-resistant hook 15. The fixing hole 71 is formed through the resin portion 33 and the metal plate portion 21 in the main body piece portion 35 formed in a laminated shape by covering the metal plate portion 21 with the resin portion 33. For this reason, both the resin part 33 and the metal plate part 21 are simultaneously fixed to the end part 17 of the slat 19. As a result, the wind-resistant hook 15 can be firmly fixed to the slat 19.

  In the above embodiment, the case where the pair of restricting pieces 45 are provided on the main body piece portion 35 of the wind-resistant hook 15 and the wind-resistant hook 15 is attached to every other slat 19 of the slat curtain 11 has been described as an example. In the structure of the shutter curtain according to the present invention, a wind-resistant hook provided with one regulating piece 45 in the main body piece portion may be attached to all the slits 49. According to such a structure, the wind-proof hook retaining portion 37 fixed to all the slats 19 engages with the guide rail 13, so that wind resistance can be further improved.

  Therefore, according to the structure of the shutter curtain according to the present embodiment, it is possible to prevent the noise generated due to the caulking portion for preventing the lateral displacement between the slats, the guide rail 13 and the silencer 55 from being damaged. In addition, it is possible to prevent the slat curtain 11 from coming off from the guide rail 13 and eliminates the need for a caulking portion, thereby eliminating complicated shape processing and complicated caulking processing, improving productivity, and manufacturing cost. Can be reduced.
