[Technical Field]

[0001] The present invention relates to an opening and closing device that has an improved effect of preventing the widthwise ends of an opening and closing body from coming off guide rails. [Background technology]

[0002] In an opening and closing device (shutter device) comprising an opening and closing body for opening and closing an opening formed in an architectural structure, and a guide rail having a guide groove disposed on both left and right widthwise end sides of the opening and closing body to guide the widthwise end of the opening and closing body along the opening and closing direction of the opening and closing body, a locking mechanism is provided within the guide rail to prevent the opening and closing body from falling off the guide rail, the locking mechanism comprising a lock plate (engagement means) having a fixed portion (mounting portion) formed by one end side of a plate body attached to the widthwise end (mounting surface) of the opening and closing body, and a claw portion (engagement portion) formed by bending the other end side of the plate body that extends widthwise outward beyond the widthwise end edge of the opening and closing body, and a locking mechanism attached to the inner peripheral surface of the guide rail An opening and closing device is known which is provided with a locking body (locking means) arranged on the plate body and having an abutment surface facing the surface of the claw portion, and anti-slip means, wherein the claw portion is formed by bending the other end side of the plate body so that it is inclined toward the side where the locking body is located so that the angle between the surface of the claw portion and the surface of the fixing portion is an obtuse angle, and the surface of the claw portion is provided at a position spaced from the widthwise edge of the opening and closing body and is configured to be spaced from the abutment surface of the locking body or to be in contact with the abutment surface of the locking body to prevent the opening and closing body from falling off the guide rail, and the anti-slip means is configured as a plurality of irregularities or a plurality of grooves formed on the surface of the claw portion facing the locking body (see Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 6571397 Summary of the Invention [Problem to be solved by the invention]

[0004] In Patent Document 1, as shown in Fig. 11, for example, a locking means (lock plate) 70 includes an attachment portion (fixing portion) 70X attached to an attachment surface at a widthwise end of the opening / closing body, and an engagement portion 70Y extending outward in the width direction from the widthwise end edge of the opening / closing body and capable of being engaged with an engagement means (locking body) not shown. The opening / closing body is formed, for example, by a plurality of slats 41, 41..., and the attachment portion 70X of the locking means 70 is attached to an attachment surface at a widthwise end of one or more of the plurality of slats 41, 41... by welding or the like. In Patent Document 1, the attachment surface is the plate surface (reference surface 42c) of the slat face plate portion 42 of the slat 41. That is, in a conventional opening and closing device, as shown in FIG. 11, for example, the mounting surface to which the mounting portion 70X of the engaging means 70 is attached by welding or the like, i.e., the reference surface 42c which is the plate surface of the slat panel portion 42, is formed as a curved surface that curves along the opening and closing direction V of the opening and closing body, whereas the mounting portion 70X is composed of a flat plate having one plate surface 70m formed on a plane along the opening and closing direction V of the opening and closing body, and the other plate surface 70n formed on a plane facing and parallel to the one plate surface 70m. The upper and lower edges of one plate surface 70m facing the reference surface 42c, which serves as the mounting surface, in the opening / closing direction V are welded to the reference surface 42c. That is, in this case, the locked means 70 and the slat face plate portion 42 of the opening / closing body are joined by an upper welded joint wa, where the contact portion between the upper edge of one plate surface 70m of the locked means 70 in the opening / closing direction V and the reference surface 42c is welded, and a lower welded joint wb, where the contact portion between the lower edge of one plate surface 70m of the locked means 70 in the opening / closing direction V and the reference surface 42c is welded. In such a joint structure between the engaging means 70 and the slat panel portion 42 of the opening / closing body, when force from the engaging means 70 is applied to the slat panel portion 42, the force is received by the slat panel portion 42 located between the upper welded joint wa and the lower welded joint wb, which is determined by the vertical width L along the opening / closing direction V of one of the panel surfaces 70m of the mounting portion 70X. Therefore, the shorter the vertical width L of the slat face plate portion 42 present between the upper welded joint wa and the lower welded joint wb (≈ the vertical width L of one plate surface 70m), the smaller the strength against the force received from the locking means 70, making the slat face plate portion 42 more likely to deform. When the slat face plate portion 42 deforms in this way, the locking means 70 becomes more likely to come off the locking means of the guide rail, and the widthwise end of the opening / closing body becomes more likely to come off the guide rail, which is a problem.

[0005] In order to solve the above-mentioned problems, the present invention provides an opening and closing device that is configured by attaching a locking means to the mounting surface of the widthwise end of the opening and closing body, and can suppress deformation of the widthwise end of the opening and closing body, thereby improving the effectiveness of preventing the widthwise end of the opening and closing body from slipping out of the guide rail.

DETAILED DESCRIPTION OF THE INVENTION

[0008] Embodiment 1 As shown in FIG. 1, an opening / closing device 1 according to the first embodiment, which is also called a shutter or shutter device, includes an opening / closing body storage case (hereinafter abbreviated as case) 2, an opening / closing mechanism 3, an opening / closing body 4, and a guide rail 5. In this specification, the "front-to-back direction of the opening 13 formed in the architectural structure" refers to a direction perpendicular to the opening / closing direction (up-down direction) V of the opening / closing body 4 that opens and closes the opening 13 and the width direction (left-right direction) W of the opening / closing body 4. Furthermore, the front side of opening 13 is "either the indoor side or the outdoor side," and the rear side of opening 13 is "either the indoor side or the outdoor side." That is, the front side of opening 13 shown in Fig. 1 may be the outdoor side and the rear side of opening 13 may be the indoor side, or the front side of opening 13 may be the indoor side and the rear side of opening 13 may be the outdoor side. In Fig. 5, the rear side of opening 13 is defined as one of the indoor side and the outdoor side, and the front side of opening 13 is defined as the other of the indoor side and the outdoor side. Furthermore, "architectural structures" refers to so-called buildings such as detached houses, apartment buildings, buildings, warehouses, factories, etc., exterior structures such as garages, carports, gates, and fences, and structures such as tunnels and underground shopping malls.

[0009] The opening and closing mechanism 3 is provided inside the case 2 on the storage side. The opening / closing mechanism 3 includes a winding body 20 such as a winding shaft or a winding frame that winds up the opening / closing body 4, and an opening / closing drive means (not shown) that rotates the winding body 20 around the rotation center line 21 of the winding body 20 as the center of rotation. In the case of an electric shutter device, the opening / closing drive means is composed of an electric motor as a drive source (not shown) that rotates the winding body 20 in the winding direction and the unwinding direction, and a power transmission mechanism such as a gear transmission mechanism that transmits the rotational force of the electric motor to the winding body 20; in the case of a manual shutter device, it is composed of a spring (not shown) that rotates the winding body 20 in the winding direction, and a power transmission means such as a pulley that transmits the rotational force stored in the spring to the winding body 20. The winding body 20 is rotatably supported, for example, by bearings (not shown) attached at both ends to the left and right brackets 22, 22 of the case 2, and rotates in the direction of winding up the opening / closing body 4 and in the direction of unwinding (unwinding) the opening / closing body 4.

[0010] The opening / closing body 4 is configured to include an opening / closing body main body 4A with one end (upper end) located on the storage section side and connected to the winding body 20, for example, via a hanging point not shown in the figure, and an other end component member 4B provided at the other end (lower end) of the opening / closing body main body 4A. The opening / closing body 4 is called, for example, a shutter curtain. The opening / closing body main body 4A is called, for example, a slat curtain. The other end component 4B is called, for example, a seat plate or a water drain.

[0011] The opening / closing body main body 4A is formed by connecting a plurality of slats 41, 41 . Each slat 41 is provided with a connecting means formed of a long, elongated member, for example made of metal, that is long in one direction, i.e., along the left and right width direction W (see Figure 1) of the opening 13 of the architectural structure in which the opening / closing device 1 is installed, and that is continuous along a pair of long side edges. That is, as shown in Figure 2, for example, each slat 41 is formed in a shape that includes a slat panel portion 42 that forms a slat surface that is slightly curved along the short side direction (opening / closing direction V (see Figure 1)), upper and lower wall panel portions 44, 44 that extend from both ends of the short side direction of the slat panel portion 42 in a direction intersecting the extension direction of the slat panel portion 42 and face each other from above and below, and connecting means that are provided to extend further beyond the extended ends of the upper and lower wall panel portions 44, 44. The connection between the slats 41 is achieved by connecting the connection means of one slat 41 to the connection means of the other slat 41 to be connected. The connecting means is constituted by curled portions 43, 43 provided along one long side edge and the other long side edge of each slat 41 and formed into a shape that allows them to engage with each other.

[0012] After engaging one longitudinal end of one curled portion 43 of one slat 41 to be connected with the other longitudinal end of the other curled portion 43 of the other slat 41, one or both slats 41 are moved laterally along the longitudinal direction so that the longitudinal ends and the longitudinal ends of both slats 41, 41 coincide with each other, thereby engaging one curled portion 43 of one slat 41 with the other curled portion 43 of the other slat 41 across the entire longitudinal width of the slat 41. In this way, one slat 41 and the other slat 41 are connected to each other in a bendable manner using the curled portions 43, 43 as joints.

[0013] As described above, the opening / closing body main body 4A is configured with a plurality of slats 41, 41... in which adjacent slats 41 and the other slats 41 are connected by curled portions 43, 43, and the opening / closing body 4 is configured by providing the other end component 4B at the other end (lower end) of the opening / closing body main body 4A. The left and right end portions 40, 40 sides in the width direction W of each of the plurality of slats 41, 41 . . . that constitute the opening / closing body main body 4A are configured to fit into the guide grooves 5a, 5a of the left and right guide rails 5, 5.

[0014] The other end component 4B, like the slat 41, is formed of a long, elongated member made of, for example, metal that is long along the width direction W (see Figure 1) of the opening 13 of the architectural structure in which the opening / closing device 1 is installed, and its cross-sectional shape perpendicular to the longitudinal direction is formed, for example, in an inverted T shape. That is, the other end component 4B is formed from an elongated member that is long in the width direction W of the opening 13, and has a vertical portion 4a that forms the vertical part of the inverted T-shaped cross section, and a horizontal portion 4b that forms the horizontal part of the inverted T-shaped cross section. A connecting means such as a curled portion (not shown) formed along the long side of the vertical portion 4a of the other end component 4B is connected to the curled portion 43 of the slat 41 located at the other end of the opening / closing body main body 4A, with the longitudinal center position of the other end component 4B and the longitudinal center position of the slat 41 aligned. Then, the lower surface of the horizontal portion 4b of the other end component 4B rests on a seating surface such as a floor surface below the opening 13, whereby the opening 13 is closed by the opening / closing body 4. Furthermore, for example, the left and right end portions 40, 40 sides in the width direction W of the vertical portion 4a and horizontal portion 4b of the other end component 4B, or the left and right end portions 40, 40 sides in the width direction W of at least one of the vertical portion 4a and horizontal portion 4b of the other end component 4B, are configured to fit into the guide grooves 5a, 5a of the left and right guide rails 5, 5. In addition, the left and right ends 40, 40 of the vertical portion 4a and horizontal portion 4b of the other end component 4B in the width direction W may be configured so as not to enter the guide grooves 5a, 5a of the left and right guide rails 5, 5.

[0015] The hanging point (not shown) is a connecting plate intermittently provided along the long side of the slat 41 (topmost slat) located at one end of the opening / closing body main body 4A, and is connected to the winding body 20 via an outlet hole (not shown) of the opening / closing body 4 in the case 2 fixed to the main body 14 located above the opening 13 of the building structure.

[0016] The case 2 houses the opening / closing mechanism 3 and the opening / closing body 4, and is a box-shaped body having a cross-sectional shape perpendicular to the longitudinal direction, for example, a rectangular shape, configured to form a storage space for the opening / closing mechanism 3 and the opening / closing body 4. The case 2 is fixed to a body 14 serving as an attachment part located above the opening 13 so that the positions of both longitudinal ends correspond to the upper end positions of the guide rails 5, 5 provided at both ends of the left and right width directions W of the opening 13. The skeleton 14 of the building structure is a steel skeleton made of H-shaped steel or the like, a concrete skeleton, a reinforced concrete skeleton, a wooden skeleton, or the like.

[0017] The guide rails 5, 5 are arranged on both left and right widthwise ends of the opening / closing body 4 that opens and closes the opening 13 formed in the architectural structure, and are provided on the left and right sides of the opening 13 to guide the left and right widthwise end portions 40, 40 of the opening / closing body 4 along the opening / closing direction V of the opening / closing body 4 (the up and down direction of the opening 13). That is, the left and right widthwise end portions 40, 40 of the opening / closing body 4 are inserted into the guide grooves 5a, 5a of the guide rails 5, 5 arranged on the left and right sides of the opening 13, and when the opening / closing body 4 is opened or closed, the left and right widthwise end portions 40, 40 of the opening / closing body 4 are guided in the opening / closing direction V within the guide grooves 5a, 5a of the left and right guide rails 5, 5. In other words, the guide rails 5, 5 are guide means that are arranged on both left and right widthwise ends of the opening / closing body 4 that opens and closes the opening 13 formed in the architectural structure, and have guide grooves 5a that guide the left and right widthwise ends 40, 40 of the opening / closing body 4 along the opening / closing direction V of the opening / closing body 4.

[0018] The opening / closing body 4 of the opening / closing device 1 configured as described above is wound onto the winding body 20 to open the opening 13 of the building structure, and the opening / closing body 4 is unwound (rolled out) from the winding body 20 to close the opening 13.

[0019] As shown in Figures 1 to 8, in the opening and closing device 1 of embodiment 1, locking means 6 are provided in the guide grooves 5a of the left and right guide rails 5, 5, and locking means 7 are provided on the left and right widthwise ends 40, 40 of the opening and closing body 4 to lock onto the locking means 6 and prevent the widthwise ends 40 of the opening and closing body 4 from slipping out of the guide grooves 5a.

[0020] For example, as shown in Figures 5 to 8, the locking means 6 is formed along a plane perpendicular to the front-to-back direction of the opening 13 (in other words, along the surface of the opening / closing body 4 closing the opening 13) and on a plane parallel to the plane perpendicular to the front-to-back direction of the opening 13, and is equipped with a vertical surface 6A that extends continuously in the opening / closing direction V of the opening / closing body 4 (a direction perpendicular to the plane of the paper in Figure 8(b)), and a locking surface 6B that extends from one vertical edge of the vertical surface 6A located on the bottom side of the guide groove 5a and is formed by a vertical surface perpendicular to the vertical surface 6A, and extends continuously in the opening / closing direction V of the opening / closing body 4, and the corner of the boundary between the vertical surface 6A and the locking surface 6B is formed as an locking angle 6C that extends continuously in the opening / closing direction V of the opening / closing body 4.

[0021] For example, as shown in Figures 2 to 4, the engaging means 7 is composed of a plate material such as a steel plate having a thickness of approximately several mm, and includes an attachment plate portion 7X that functions as an attachment portion attached to the attachment surface 42a of the widthwise end portion 40 of the opening / closing body 4, and an engaging plate portion 7Y that extends widthwise outward beyond the widthwise end edge 41s of the opening / closing body 4 and functions as an engaging portion that can be engaged with the engaging means 6. That is, the engaging means 7 is configured such that one end side, the mounting plate portion 7X, is attached to the mounting surface 42a of the widthwise end portion 40 of the opening / closing body 4 by welding or the like, and the other end side, which extends and protrudes outward in the widthwise direction beyond the widthwise end edge 41s of the opening / closing body 4, functions as an engaging plate portion 7Y that engages with the engaging means 6 (see Figure 2).

[0022] The mounting portion of the locked means 7 is configured by a mounting plate portion 7X having one plate surface 7E facing the mounting surface 42a and the other plate surface 7F facing the one plate surface 7E. The mounting surface 42a of the widthwise end 40 of the slat 41 that constitutes the opening / closing body 4 is configured to include a reference surface 42c extending along the opening / closing direction V, and opposing end side wall surfaces 42b, 42b (i.e., upper end side wall surfaces and lower end side wall surfaces that face each other above and below the opening / closing direction V) that are arranged to extend from both ends of the reference surface 42c in the opening / closing direction V in a direction intersecting the reference surface 42c. As shown in Figure 3(b), if the lines indicating both plate surfaces of the plates constituting the slat panel portion 42 are each considered to be part of a concentric circle, and the plate surface closer to the center of the concentric circle is defined as the inner curved surface 42i, and the plate surface farther from the center of the concentric circle is defined as the outer curved surface 42f, then the above-mentioned reference surface 42c is formed by the inner curved surface 42i of the slat panel portion 42. That is, the reference surface 42c of the mounting surface 42a is formed as a curved surface that curves along the opening / closing direction V of the opening / closing body 4. The end side wall surface 42b is formed by the inner surface of the wall plate portion 44 of the slat 41 (the plate surface close to the center of the above-mentioned concentric circle). Then, the upper edge 7t in the opening / closing direction V of one plate surface 7E of the mounting plate portion 7X is welded to the upper end side wall surface 42b of the mounting surface 42a, and the lower edge 7t in the opening / closing direction V of one plate surface 7E of the mounting plate portion 7X is welded to the lower end side wall surface 42b of the mounting surface 42a, thereby joining the engaging means 7 and the slat 41 of the opening / closing body 4.

[0023] The engaging plate portion 7Y has a plate surface that is continuous with one of the plate surfaces 7E of the mounting plate portion 7X and is formed as an engaging surface 7A that can come into contact with the engaging angle 6C of the engaging means 6 (see Figure 8(b)), and the engaging surface 7A is configured to have an engaging recess 7a (see Figures 4(a) and 8(b)) that can engage with the engaging angle 6C and engaging surface 6B of the engaging means 6.

[0024] That is, the engaging means 7 is formed on an attachment plate portion 7X whose one end is attached to the widthwise end portion 40 of the opening / closing body 4, and the other end extending from one plate surface 7E of the attachment plate portion 7X is provided with an engaging plate portion 7Y having an engaging surface 7A that can come into contact with the engaging angle 6C of the engaging means 6 and an engaging recess 7a that can engage with the engaging angle 6C and engaging surface 6B of the engaging means 6.

[0025] The engaging means 7 is formed, for example, by bending the other longitudinal end of a rectangular steel plate so that the angle θ (see Figure 4(c)) between a reference plane 7m (described later) on one plate surface 7E, which is the plate surface on one end side of the longitudinal direction of the steel plate, and an engaging surface 7A, which extends continuously from the reference plane 7m and is the plate surface on the other end side of the longitudinal direction of the steel plate, is, for example, approximately 135°±10°.

[0026] The engaging means 7 is provided, for example, on the end 40, 40... sides of all slats 41, 41... constituting the opening / closing body main body 4A and on the end 40 side of the other end component member 4B, which are configured to fit into the guide grooves 5a, 5a of the left and right guide rails 5, 5, or on the end 40 side of any of the slats 41, 41... constituting the opening / closing body main body 4A and the other end component member 4B.

[0027] In the first embodiment, as shown in, for example, FIGS. 4 and 8(a), the locked recess 7a is configured as a recess having a triangular cross section provided on the locked surface 7A. That is, as shown in Figure 4, the engaging recess 7a is provided on the engaging surface 7A at the tip end side in the extension direction of the engaging surface 7A extending from one plate surface 7E, and as shown in Figure 3(b), is formed by a recess with a triangular cross section that continues along the opening and closing direction V of the opening and closing body 4. The locked means 7 having the locked recess 7a may be formed by press molding the locked surface 7A using a press die, or by cutting or other methods.

[0028] One of the plate surfaces 7E of the mounting plate portion 7X attached to the mounting surface 42a is formed into a non-planar surface corresponding to the curved surface that forms the above-mentioned reference surface 42c (the inner curved surface 42i of the slat surface plate portion 42). One of the plate surfaces 7E is formed in a non-planar shape corresponding to the curved surface that forms the reference surface 42c, specifically, in a pseudo-curved surface 7G that corresponds to the curved surface that forms the reference surface 42c, along the curved surface that forms the reference surface 42c. More specifically, the pseudo-curved surface 7G forming the one plate surface 7E is a pseudo-curved surface having a reference plane 7m extending along the opening / closing direction V, and end side planes (i.e., upper end side plane and lower end side plane) 7e, 7e extending from both the upper and lower ends of the reference plane 7m in the opening / closing direction V in a direction intersecting the reference plane 7m and away from each other, as shown in Figure 3(b). In other words, one of the plate surfaces 7E formed by the pseudo-curved surface 7G is formed as a bent surface composed of multiple planes 7m, 7e, 7e so as to approximate the curved surface forming the reference surface 42c (the inner curved surface 42i of the slat panel portion 42). The mounting plate portion 7X is formed by bending both upper and lower ends in the opening and closing direction V, for example. The other plate surface 7F is formed on a pseudo-curved surface 7G that faces parallel to the pseudo-curved surface 7G that forms one plate surface 7E.

[0029] As shown in Figure 3(b), the boundary edges BH, BL between the reference plane 7m of one plate surface 7E of the mounting plate portion 7X and the end side planes 7e, 7e are in contact with the reference surface 42c of the mounting surface 42a, and the upper welded joint wa is formed by welding the contact portion between the upper edge 7t of the one plate surface 7E in the opening / closing direction V and the end side wall surface (upper end side wall surface) 42b, and the lower welded joint wb is formed by welding the contact portion between the lower edge 7u of the one plate surface 7E in the opening / closing direction V and the end side wall surface (lower end side wall surface) 42b. In other words, the boundary edges BH, BL between the reference plane 7m of one plate surface 7E and the end side planes 7e, 7e come into contact with the reference surface 42c of the mounting surface 42a, and the edge of the end side planes 7e, 7e of one plate surface 7E is welded to the end side wall surfaces 42b, 42b of the mounting surface 42a, thereby joining the engaging means 7 and the slat 41 of the opening / closing body 4.

[0030] Therefore, when force from the engaging means 7 is applied to the slat 41, the force is received by the slat face plate portion 42 and the upper and lower wall plate portions 44, 44 located between the upper welded joint wa and the lower welded joint wb, thereby increasing the strength against the force received from the engaging means 7. Therefore, the slats 41 are less likely to deform, the locked means 7 is less likely to come off the locking means 6 of the guide rail 5, and the width direction end 40 of the opening / closing body 4 is less likely to come off the guide rail 5. In particular, the plate portion composed of the slat face plate portion 42, which forms the reference surface 42c of the mounting surface 42a and each end side wall surface 42b, 42b, and the upper and lower wall plate portions 44, 44, is composed of a strong plate portion with a U-shaped cross section formed so that the boundary portion between the slat face plate portion 42 and the wall plate portion 44 becomes a corner, making the slat 41 less likely to deform. Thus, according to embodiment 1, deformation of the widthwise end 40 of the opening / closing body 4, which is configured by attaching the engaging means 7 to the mounting surface 42a of the widthwise end 40 of the opening / closing body 4, can be suppressed, and an opening / closing device 1 can be provided that has an improved effect of preventing the widthwise end 40 of the opening / closing body 4 from coming off the guide rail 5. Furthermore, according to embodiment 1, the opposing plate surfaces 7E and the reference surface 42c are configured so that the boundary edges BH, BL are in contact with the reference surface 42c, i.e., at least a portion of the opposing plate surfaces 7E and the reference surface 42c are in contact with each other. This improves the support force when force from the engaging means 7 is applied to the slat panel portion 42, making the slat panel portion 42 less likely to deform.

[0031] As in embodiment 4 shown in Figure 10 described later, an attachment plate portion 7X may be configured as a flat plate having one plate surface 7E and the other plate surface 7F that are parallel to each other and form a single plane, and both ends of the attachment plate portion 7X along the opening / closing direction V may be attached to the end side wall surfaces 42b, 42b. However, in this configuration, the position of the mounting plate portion 7X moves in a direction approaching the center of the concentric circle (in a direction away from the slat face plate portion 42 to the left on the paper in FIG. 10(b)), and therefore the length D of the engaging plate portion 70Y, which functions as the engaging portion, that can be engaged with the engaging means 6 (i.e., the shortest distance between the tip of the engaging surface 7A and the outer curved surface 42f of the slat face plate portion 42) becomes shorter by the amount of this movement. For example, as is clear from a comparison of the configurations in FIG. 10 and 11, the longer the vertical width L of the mounting plate portion 7X, as in the configuration in FIG. 10, the shorter the engaging length D becomes. In this way, if the engagement length D becomes shorter, the engagement plate portion 7Y of the engagement means 7 becomes more likely to come off from the engagement means 6 of the guide rail 5, and there is a risk that the wind resistance performance based on the engagement between the engagement plate portion 7Y and the engagement means 6 will not be fully demonstrated. On the other hand, according to embodiment 1, one of the plate surfaces 7E is formed into a pseudo-curved surface 7G having a reference plane 7m and each end side plane 7e, 7e, thereby reducing the amount of movement of the position of the mounting plate portion 7X in the direction approaching the center of the above-mentioned concentric circle compared to the configuration shown in Figure 10, and making it possible to prevent the engagement length D of the engaged plate portion 7Y relative to the engagement means 6 from becoming shorter. In other words, if the size and shape of the plate-engaged portion 7Y are the same in embodiment 1 and embodiment 4 described below, the length D at which the plate-engaged portion 7Y can be engaged with the engaging means 6 is longer in embodiment 1. That is, according to embodiment 1, by using an engaging means 7 in which one plate surface 7E is formed by a pseudo-curved surface 7G having a reference plane 7m and each end side plane 7e, 7e, the engaging length D of the engaging plate portion 7Y relative to the engaging means 6 can be increased, making it difficult for the engaging plate portion 7Y to come off the engaging means 6. Therefore, according to the locked means 7 of the first embodiment, wind resistance based on the locking between the locked surface 7A and the locking means 6 can be fully exhibited.

[0032] Furthermore, as shown in Figure 3(a), the engaging means 7 of embodiment 1 is configured so that the vertical width L of the mounting plate portion 7X along the opening / closing direction V is longer than the vertical width L1 of the engaging plate portion 7Y along the opening / closing direction V. In other words, the vertical width L1 of the locked plate portion 7Y along the opening / closing direction V can be reduced, thereby making the locked plate portion 7Y more compact.

[0033] In the opening / closing device 1 of embodiment 1, for example, as shown in Figure 5, when a force is applied to the opening / closing body 4 in the direction of arrow F1 in Figure 6 from a state in which no force is applied to the opening / closing body 4 from the front-to-back directions of the opening 13, the engaging surface 7A of the engaging means 7 and the engaging angle 6C of the engaging means 6 come into contact, and further, the engaging recess 7a of the engaging means 7 engages with the engaging angle 6C and engaging surface 6B of the engaging means 6, thereby improving the effect of preventing the widthwise end 40 of the opening / closing body 4 from coming off the guide rail 5. Similarly, when a force is applied in the direction of arrow F2 in Figure 7 (a force in the opposite direction to F1), the engaging surface 7A of the engaging means 7 and the engaging angle 6C of the engaging means 6 come into contact, and further, the engaging recess 7a of the engaging means 7 engages with the engaging angle 6C and engaging surface 6B of the engaging means 6, thereby improving the effect of preventing the widthwise end 40 of the opening / closing body 4 from coming off the guide rail 5. Furthermore, as shown in Figure 5, when no force is applied to the opening / closing body 4 from the front to back direction of the opening 13, the engaging surface 7A and the engaging means 6 do not come into contact, and the opening / closing body 4 is configured to open and close smoothly. 5 to 7 are cross-sectional views perpendicular to the extension direction of the guide rail 5 in FIG.

[0034] Next, a specific example of the guide rail 5 will be described with reference to FIGS. As shown in Figure 1, the guide rail 5 is attached to a frame 14 made of, for example, H-shaped steel via a reinforcing member 8 and an attachment member 9 that reinforce the guide rail 5, so that the guide rail 5 is installed in the building structure while being reinforced by the reinforcing member 8, thereby ensuring strength. The guide rail 5, the reinforcing member 8, and the mounting member 9 will be described in detail below.

[0035] As shown in FIG. 5, the guide rail 5 is configured to include a guide rail main body 5A and a decorative portion 5B. As shown in Figure 5, the guide rail main body 5A is composed of a hollow, elongated object that has a roughly U-shaped cross section with a groove entrance 5b of a predetermined width and that has a guide groove 5a that continues in one direction (a direction perpendicular to the paper surface of Figure 5) formed therein. The decorative portion 5B is composed of a member that covers the inner surface of the guide groove 5a of the guide rail main body 5A and the surface of the side wall 50 so that the inner surface of the guide groove 5a of the guide rail main body 5A and the side wall 50 on the groove entrance 5b side of the guide rail main body 5A are not visible when the guide rail 5 is viewed from the outside.

[0036] The guide rail main body 5A is composed of a long, hollow metal column-like object with a concave cross section, in which a guide groove 5a having a groove entrance 5b for inserting the left widthwise end portion 40 of the opening / closing body 4 or the right widthwise end portion 40 of the opening / closing body 4 is formed so as to continue in the opening / closing direction V of the opening / closing body 4 (vertical direction (direction perpendicular to the plane of the paper in Figure 5)). The guide rail main body 5A is configured by combining two members, that is, a first rail member 51 and a second rail member 52, for example. The first rail material 51 and the second rail material 52 are formed by bending or otherwise shaping a metal plate (e.g., a flat metal plate) made of steel, stainless steel, aluminum, or the like, which is long in one direction and has a predetermined width in a direction perpendicular to that direction and has a thickness of approximately several mm.

[0037] The first rail material 51 has a guide groove one side wall portion 53 that forms the wall on one side of the guide groove 5a (for example, the rear side of the opening 13), and a one side wall portion 54 that forms one side wall of the side wall 50. The guide groove one side wall portion 53 includes a groove entrance side wall portion 55 located on the groove entrance 5b side, a bottom side wall portion 56 located on the bottom side of the guide groove 5a, and a locking wall portion 57 formed by a step wall portion that forms the boundary between the groove entrance side wall portion 55 and the bottom side wall portion 56. In other words, the first rail material 51 is a long member that extends continuously in the opening and closing direction (up and down direction) of the opening and closing body 4, and is configured to include a side wall portion 54 that extends a predetermined length from one end located on one side (for example, the rear side of the opening 13) to the other side, a groove entrance side wall portion 55 that extends a predetermined length from the extended end of the side wall portion 54 in the width direction of the opening and closing body 4, a locking wall portion 57 that extends a predetermined length from the extended end of the groove entrance side wall portion 55 to one side, and a bottom side wall portion 56 that extends a predetermined length from the extended end of the locking wall portion 57 in the width direction of the opening and closing body 4 and in a direction away from the side wall portion 54. Furthermore, one side edge of the groove entrance 5b of the guide groove 5a is formed by the boundary between the one side wall portion 54 and the groove entrance side wall portion 55, and for example, the plate surface of the one side wall portion 54 and the plate surface of the groove entrance side wall portion 55 are formed so as to be perpendicular to each other via the boundary between the one side wall portion 54 and the groove entrance side wall portion 55. Furthermore, for example, the plate surface of the groove inlet side wall portion 55 and the plate surface of the locking wall portion 57 are formed so as to be perpendicular to each other via the boundary portion between the groove inlet side wall portion 55 and the locking wall portion 57 . Furthermore, for example, the plate surface of the locking wall portion 57 and the plate surface of the bottom side wall portion 56 are formed so as to be perpendicular to each other via the boundary portion between the locking wall portion 57 and the bottom side wall portion 56.

[0038] The second rail material 52 includes a guide groove other side wall portion 63 that forms the side wall on the other side of the guide groove 5a (for example, the front side of the opening 13), an other side wall portion 64 that forms the side wall on the other side of the side wall 50, a guide groove bottom surface portion 65 that forms the bottom surface of the guide groove 5a, a bottom side wall portion 66 located on the bottom side of the guide groove 5a, and a locking wall portion 67. In other words, the second rail material 52 is an elongated member that extends continuously in the opening / closing direction (up and down direction) of the opening / closing body 4, and is configured to include a second side wall portion 64 that extends a predetermined length to one side from one end located on the other side (for example, the front side of the opening 13), a guide groove second side wall portion 63 that extends a predetermined length from the extended end of the second side wall portion 64 in the width direction of the opening / closing body 4, a guide groove bottom surface portion 65 that extends a predetermined length to one side from the extended end of the guide groove second side wall portion 63, a bottom side wall portion 66 that extends a predetermined length from the extended end of the guide groove bottom surface portion 65 in the width direction of the opening / closing body 4 and in a direction approaching the second side wall portion 64, and a locking wall portion 67 that extends a predetermined length to the other side from the extended end of the bottom side wall portion 66. The end of the locking wall portion 67 in the extension direction is configured to function as the locking means 6 described above. Furthermore, the boundary between the other side wall portion 64 and the other side wall portion 63 of the guide groove forms the other side edge portion of the groove entrance 5b of the guide groove 5a, and for example, the plate surface of the other side wall portion 64 and the plate surface of the other side wall portion 63 of the guide groove are formed so as to be perpendicular to each other via the boundary between the other side wall portion 64 and the other side wall portion 63 of the guide groove. Furthermore, for example, the plate surface of the guide groove other side wall portion 63 and the plate surface of the guide groove bottom surface portion 65 are formed so as to be perpendicular to each other via the boundary between the guide groove other side wall portion 63 and the guide groove bottom surface portion 65. Also, for example, the plate surface of the guide groove bottom surface portion 65 and the plate surface of the bottom side wall portion 66 are formed so as to be perpendicular to each other via the boundary portion between the guide groove bottom surface portion 65 and the bottom side wall portion 66 . Also, for example, the plate surface of the bottom wall portion 66 and the plate surface of the locking wall portion 67 are formed so as to be perpendicular to each other via the boundary between the bottom wall portion 66 and the locking wall portion 67 .

[0039] The decorative portion 5B includes an inner decorative plate 71, an other-side decorative plate 72, and a one-side decorative plate 73. The inner decorative panel 71, the other side decorative panel 72, and the one side decorative panel 73 are formed by bending or otherwise shaping a metal plate (e.g., a flat metal plate) such as steel, stainless steel, aluminum, etc., which is long in one direction and has a predetermined width in a direction perpendicular to that direction and is several millimeters thick. Furthermore, the metal plates forming the inner decorative panel 71, the other side decorative panel 72, and the one side decorative panel 73 may be thinner than the metal plates forming the first rail material 51 and the second rail material 52, and may have decorative treatments such as coloring, patterns, gloss or matte finishes applied to the surface.

[0040] The inner decorative panel 71 is attached to the inner surface of the other side wall portion 63 of the guide groove of the second rail material 52 and the inner surface of the bottom surface 65 of the guide groove, and is a decorative panel that prevents the inner surface of the other side wall portion 63 of the guide groove of the second rail material 52 and the inner surface of the bottom surface 65 of the guide groove from being seen when the inside of the guide groove 5a is viewed through the groove entrance 5b of the guide groove 5a of the guide rail 5. That is, the inner decorative plate 71 includes a guide groove other side cover portion 74 that covers the inner surface of the guide groove other side wall portion 63 and a guide groove bottom side cover portion 75 that covers the inner surface of the guide groove bottom portion 65. For example, the plate surface of the guide groove other side cover portion 74 and the plate surface of the guide groove bottom side cover portion 75 are formed so as to be perpendicular to each other via the boundary between the guide groove other side cover portion 74 and the guide groove bottom side cover portion 75. Furthermore, when the inside of the guide groove 5a is viewed through the groove entrance 5b of the guide groove 5a of the guide rail 5, one side portion of the inner surface of the guide groove bottom portion 65 is blocked by the groove entrance side wall portion 55 of the first rail material 51 and the engagement wall portion 67 of the second rail material 52, creating a blind spot, so on the inner surface of the guide groove bottom portion 65, the portion between one end of the guide groove bottom side covering portion 75 and the bottom side wall portion 66 is an uncovered portion.

[0041] The other side decorative panel 72 is attached to the surface of the other side wall portion 64 of the second rail material 52 and the inner surface of the groove entrance 5b side of the guide groove other side wall portion 63, and is a decorative panel to prevent the surface of the other side wall portion 64 of the second rail material 52 and the inner surface of the groove entrance 5b side of the guide groove other side wall portion 63 from being seen visually. The other side decorative panel 72 includes an other side wall covering portion 76 that covers the surface of the other side wall portion 64 of the second rail material 52, and an other side wall surface covering portion 77 that covers the inner surface of the opening side of the guide groove other side wall portion 63. For example, the plate surface of the other side wall covering portion 76 and the plate surface of the other side wall surface covering portion 77 are formed so as to be perpendicular to each other via the boundary between the other side wall covering portion 76 and the other side wall surface covering portion 77 .

[0042] The one-side decorative panel 73 is attached to the surface of one side wall portion 54 of the first rail material 51 and the inner surface of the groove entrance side wall portion 55, and is a decorative panel designed to prevent the surface of one side wall portion 54 of the first rail material 51 and the inner surface of the groove entrance side wall portion 55 from being seen visually. The one-side decorative plate 73 includes a one-side wall covering portion 78 that covers the surface of the one-side wall portion 54 of the first rail member 51, and a guide groove inlet one-side covering portion 79 that covers the inner surface of the groove inlet side wall portion 55. For example, the plate surface of the one side wall covering portion 78 and the plate surface of the guide groove inlet one side covering portion 79 are formed so as to be perpendicular to each other via the boundary between the one side wall covering portion 78 and the guide groove inlet one side covering portion 79.

[0043] The reinforcing member 8 may be, for example, a metal plate (e.g., a flat metal plate) made of steel, stainless steel, aluminum, or the like, with a roughly rectangular surface and a thickness of a few mm, and a notched recess formed by cutting the metal plate into a roughly rectangular shape on one side of the square, or may be formed by die-casting such as aluminum die-casting. That is, the reinforcing member 8 is composed of, for example, a flat plate member having a peripheral portion 80 formed in a shape that surrounds the outer peripheral surface 5f of the guide groove 5a into which the widthwise end portion 40 of the opening / closing body 4 is inserted. For example, when the portion forming the guide groove 5a of the guide rail 5 is inserted into the notch recess formed in the reinforcing member 8, the shape of the peripheral portion 80 of the notch recess of the reinforcing member 8 and the shape of the outer surface 5f of the guide groove 5a in the cross section of the guide groove 5a of the guide rail 5 are formed to approximately match each other. Furthermore, it is preferable that the thickness of the reinforcing member 8 be thicker than the thickness of the first rail material 51 and the second rail material 52, and it is even more preferable from the standpoint of strength that the thickness be thicker than the sum of the thickness of the first rail material 51 and the thickness of the second rail material 52.

[0044] The peripheral portion 80 of the reinforcing member 8 is composed of edge portions that face each of the plate surfaces that form the outer peripheral surface 5f of the guide groove 5a of the guide rail main body 5A, which is formed by combining the first rail material 51 and the second rail material 52, i.e., the plate surface that forms one side of the groove entrance side wall portion 55 of the first rail material 51, the plate surface that forms the groove entrance 5b side of the guide groove 5a of the engaging wall portion 57, the plate surface that forms one side of the bottom side wall portion 56, the plate surface opposite the groove entrance 5b at the guide groove bottom surface portion 65 of the second rail material 52, and the plate surface that forms the other side of the guide groove other side wall portion 63. In other words, the peripheral portion 80 of the reinforcing member 8 is composed of a groove entrance one side edge portion 81 facing the plate surface on one side of the groove entrance side wall portion 55 of the first rail material 51, a locking wall side edge portion 82 facing the plate surface on the groove entrance 5b side of the locking wall portion 57, a one bottom side side wall side edge portion 83 facing the plate surface on one side of the bottom side wall portion 56, a guide groove bottom side edge portion 84 facing the plate surface on the opposite side of the groove entrance 5b at the guide groove bottom surface portion 65 of the second rail material 52, and a other guide groove side wall side edge portion 85 facing the plate surface on the other side of the guide groove other side wall portion 63. The reinforcing member 8 also includes a one-side edge portion 86 extending to one side from one end of the groove entrance one-side edge portion 81 and facing parallel to the one-side wall portion 54, an other-side edge portion 87 extending to the other side from one end of the other guide groove side wall side edge portion 85 and facing parallel to the other side wall portion 64, and an outer edge portion 88 connecting the extended end of the one-side edge portion 86 and the extended end of the other-side edge portion 87 and surrounding the outside of the peripheral portion 80 of the reinforcing member 8. In other words, the reinforcing member 8 is a flat plate member surrounded by a peripheral edge portion 80 surrounding the outer peripheral surface 5f of the guide groove 5a of the guide rail 5, one side edge portion 86, the other side edge portion 87, and an outer edge portion 88.

[0045] The peripheral portion 80 of the reinforcing member 8 is installed so as to surround the outer peripheral surface 5f of the guide groove 5a of the guide rail 5, and at least a portion of the peripheral portion 80 side of the reinforcing member 8 and the outer peripheral surface 5f of the guide groove 5a are connected, for example, by welding.

[0046] As shown in FIG. 1, a plurality of reinforcing members 8, 8 . . . are connected to the guide rail 5 at intervals in the vertical direction (longitudinal direction, extension direction) of the guide rail 5, that is, along the opening / closing direction V of the opening / closing body 4.

[0047] The mounting member 9 is formed by bending a metal plate (e.g., a flat metal plate) made of steel, stainless steel, aluminum, or the like having a thickness of a few millimeters, or by processing an angle bar, or by die-casting such as aluminum die-casting. As shown in FIG. 1, the mounting member 9 includes a reinforcing member connecting portion 91 that is connected to the reinforcing member 8 by welding or the like, and a frame connecting portion 92 that is connected to the frame 14. The body connecting portion 92 is formed of, for example, a rectangular flat plate portion. The reinforcing member connecting portion 91 extends from one long side edge of the rectangle of the body connecting portion 92 and is formed by, for example, a flat plate portion having a plate surface perpendicular to the plate surface of the body connecting portion 92 .

[0048] For example, by previously attaching mounting members 9, 9... by welding or the like to the attachment points of the multiple reinforcing members 8, 8... connected to the guide rail 5 to the main body 14, and then attaching the multiple reinforcing members 8, 8... connected to the guide rail 5 to the corresponding mounting members 9, 9... by welding or the like, the guide rail 5 can be attached to the main body 14 in a state reinforced by the multiple reinforcing members 8, 8..., thereby improving the strength of the guide rail 5. Furthermore, if multiple reinforcing members 8, 8... connected to the guide rail 5 are attached to the main body 14 via mounting members 9, 9..., even if the vertical accuracy of the mounting surface of the main body 14 is slightly off, a guide rail 5 with high vertical accuracy can be achieved by adjusting the mounting position of each reinforcing member 8, 8... connected to the guide rail 5 relative to the mounting members 9, 9...

[0049] By using the reinforcing members 8, 8 . . . , it is possible to reduce the weight of the guide rail 5, improve workability and productivity, and also ensure the strength of the guide rail 5. Furthermore, it has become possible to provide a guide rail 5 that is lightweight, has improved workability and manufacturability, and also ensures strength. In particular, in the opening and closing device 1 according to the first embodiment that is provided with the locking means 6 and the locked means 7 described above, the guide rail 5 that requires strength can be easily constructed.

[0050] Embodiment 2 In embodiment 1, an engaging means 7 was used in which one plate surface 7E and the other plate surface 7F were provided with mounting plate portions 7X formed into pseudo-curved surfaces 7G, ​​7G corresponding to the curved surface that forms the reference surface 42c along the curved surface, but it is also possible to use an engaging means 7 in which one plate surface 7E and the other plate surface 7F are formed into true curved surfaces (not shown) corresponding to the curved surface that forms the reference surface 42c along the curved surface. In other words, the plate surface 7E, which is formed as a true curved surface, is brought into contact with the reference surface 42c of the mounting surface 42a, and the upper and lower edges 7t, 7u of the plate surface 7E are welded to the end side wall surfaces 42b, 42b of the mounting surface 42a, thereby joining the engaging means 7 and the slat 41 of the opening / closing body 4.

[0051] According to embodiment 2, as in embodiment 1, deformation of the widthwise end 40 of the opening / closing body 4, which is configured by attaching the engaging means 7 to the mounting surface 42a of the widthwise end 40 of the opening / closing body 4, can be suppressed, improving the effect of preventing the widthwise end 40 of the opening / closing body 4 from slipping off the guide rail 5.Furthermore, since one of the plate surfaces 7E formed as a true curved surface is in contact with the reference surface 42c of the mounting surface 42a, the adhesion between one of the plate surfaces 7E and the reference surface 42c is improved, and the effect of suppressing deformation of the slat 41 can be further improved. In addition, since one of the opposing plate surfaces 7E and the reference surface 42c can be configured to be in surface contact with each other, the support force is improved when force from the engaging means 7 is applied to the slat panel portion 42, making the slat panel portion 42 less likely to deform.

[0052] Embodiment 3 In each embodiment, the reference surface 42c constituting part of the mounting surface 42a is formed as a curved surface that curves along the opening / closing direction V of the opening / closing body 4, but as shown in Figure 9, the reference surface may also be a reference surface 42w formed by an uneven surface that is uneven on the left and right sides along the opening / closing direction V of the opening / closing body 4. In FIG. 9, the same or corresponding parts as those described in FIG. 3(a) of the first embodiment are denoted by the same reference numerals, and detailed description thereof will be omitted.

[0053] In other words, a slat 41 may be used in which the reference surface 42w of the mounting surface 42a has a slat panel portion 42 formed as an uneven surface having unevenness along the opening and closing direction V, and one plate surface 7E and the other plate surface 7F have a mounting plate portion 7X formed as a plane 7P extending along the opening and closing direction V. In this case, for example, as shown in Figure 9(a), one plate surface 7E of the mounting plate portion 7X comes into contact with the convex portion WC of the reference surface 42w, and the edge (i.e., the upper edge 7t, the lower edge 7u) of the other plate surface 7F of the mounting plate portion 7X is welded to the end side wall surface (i.e., the upper end side wall surface 42b, the lower end side wall surface 42b), thereby joining the engaging means 7 and the slat 41.

[0054] According to embodiment 3 shown in Figure 9(a), one plate surface 7E of the mounting plate portion 7X is in contact with the convex portion WC of the reference surface 42w, and the edge 7t, 7u of the other plate surface 7F of the mounting plate portion 7X is welded to the end side wall surfaces 42b, 42b, so that when force is applied to the slat 41 from the engaging means 7, the slat 41 is less likely to deform. In particular, the plate portion composed of the slat panel portion 42 that forms the reference surface 42w of the mounting surface 42a and each end side wall surface 42b, 42b, and the upper and lower wall panel portions 44, 44, is composed of a strong plate portion with a W-shaped cross section that is formed so that the boundary portion between the slat panel portion 42 and the wall panel portion 44 and the convex portion WC are curved, making the slat 41 less likely to deform. Therefore, according to embodiment 3, as in embodiment 1, deformation of the widthwise end 40 of the opening / closing body 4, which is configured by attaching the engaging means 7 to the mounting surface 42a of the widthwise end 40 of the opening / closing body 4, can be suppressed, and an opening / closing device 1 can be provided that has an improved effect of preventing the widthwise end 40 of the opening / closing body 4 from coming off the guide rail 5. Furthermore, one of the opposing plate surfaces 7E and the reference surface 42w is configured so that the plane 7P forming one of the plate surfaces 7E is in contact with the convex portion WC of the reference surface 42w, i.e., at least a portion of one of the opposing plate surfaces 7E and the reference surface 42w is in contact with each other. This improves the support force when force from the engaging means 7 is applied to the slat panel portion 42, making the slat panel portion 42 less likely to deform.

[0055] In the configuration shown in FIG. 9(a), the upper end surface 7g and the lower end surface 7g of the mounting plate portion 7X are formed in a plane that is perpendicular to the one plate surface 7E and the other plate surface 7F. In this case, the upper edge 7t and lower edge 7u of one plate surface 7F of the mounting plate 7X may come into contact with the upper end wall surface 42b and the lower end wall surface 42b, potentially pressing the upper end wall surface 42b and the lower end wall surface 42b away from each other. If the upper end wall surface 42b and the lower end wall surface 42b are pressed away from each other in this manner, the gap between the upper edge 7t and the upper end wall surface 42b of the other plate surface 7F of the mounting plate 7X and the gap between the lower edge 7u and the lower end wall surface 42b of the other plate surface 7F of the mounting plate 7X may become larger. If this gap becomes larger, the weld strength of the welded portion where the edges 7t, 7u of the other plate surface 7F of the mounting plate 7X are welded to the end wall surfaces 42b, 42b may be weakened. Furthermore, if this gap becomes larger, welding may not be possible depending on the performance of the welding machine.

[0056] Therefore, as shown in Figure 9(b), in order to prevent the upper edge 7t and lower edge 7u of one plate surface 7E of the mounting plate portion 7X from coming into contact with the upper end side wall surface 42b and the lower end side wall surface 42b, the vertical width of one plate surface 7E of the mounting plate portion 7X is made shorter than the vertical width of the other plate surface 7F of the mounting plate portion 7X, and the upper end surface and lower end surface of the mounting plate portion 7X are formed as inclined surfaces 7J, 7J that are inclined in a direction away from the upper end side wall surface 42b and the lower end side wall surface 42b. That is, the upper end surface of the mounting plate portion 7X is formed as an inclined surface 7J that slopes away from the upper end edge 7t of the other plate surface 7F of the mounting plate portion 7X toward the upper end edge 7t of one plate surface 7E of the mounting plate portion 7X, and the lower end surface of the mounting plate portion 7X is formed as an inclined surface 7J that slopes away from the lower end side wall surface 42b, from the lower end edge 7u of the other plate surface 7F of the mounting plate portion 7X toward the lower end edge 7u of one plate surface 7E of the mounting plate portion 7X. It is desirable that the gap be 0.5 mm or less, and more preferably 0.1 mm to 0.2 mm. According to embodiment 3 shown in Figure 9(b), it is possible to prevent the above-mentioned gap from becoming larger due to contact between the upper edge 7t and lower edge 7u of one plate surface 7F of the mounting plate portion 7X and the upper end side wall surface 42b and the lower end side wall surface 42b, and it is possible to prevent the welding strength from becoming weak when the edges 7t, 7u of the other plate surface 7F of the mounting plate portion 7X are welded to the end side wall surfaces 42b, 42b, so it is possible to achieve a good welded joint.

[0057] In other words, in the third embodiment shown in FIG. 9(b), the extension length of the other plate surface 7F of the locked means 7 along the opening / closing direction V is set to be longer than the extension length of one plate surface 7E of the locked means 7 along the opening / closing direction V, and the gap between the edge (upper edge 7t, lower edge 7u) of one plate surface 7E and the end side wall surface (upper end side wall surface 42b, lower end side wall surface 42b) is set to be longer than the gap between the edge 7t, 7u of the other plate surface 7F and the end side wall surface 42b, 42b. The gap is set to be larger than the gap between the edges 7t, 7u of the other plate surface 7F and the end side wall surfaces 42b, 42b, and the gap between the edges 7t, 7u of the other plate surface 7F and the end side wall surfaces 42b, 42b is set to be 0.5 mm or less, and the edges 7t, 7u of the other plate surface 7F and the end side wall surfaces 42b, 42b are welded together, thereby achieving the effect of realizing a good welded joint when welding the edges 7t, 7u of the other plate surface 7F and the end side wall surfaces 42b, 42b.

[0058] Embodiment 4 As shown in FIG. 10, an attachment plate portion 7X may be configured as a flat plate having one plate surface 7E and the other plate surface 7F that are parallel to each other and face each other, with both ends of the attachment plate portion 7X along the opening / closing direction V attached to the end side wall surfaces 42b, 42b. In this case, for example, as shown in FIG. 10(b), the upper end surface 7K and the lower end surface 7K of the mounting plate portion 7X may be formed as surfaces facing the upper end side wall surface 42b and the lower end side wall surface 42b, or may be formed as inclined surfaces inclined in a direction away from the upper end side wall surface 42b and the lower end side wall surface 42b, similar to the inclined surfaces 7J, 7J shown in FIG. 9(b) described above, and the end edges 7t, 7u of the other plate surface 7F of the mounting plate portion 7X may be welded to the end side wall surfaces 42b, 42b. In addition, in embodiment 4, if the length D of the plate portion 7Y that can be engaged with the engaging means 6 becomes too short, it is sufficient to use an engaging means 7 in which the extension length of the plate portion 7Y is increased as appropriate. According to embodiment 4, as in embodiment 1, deformation of the widthwise end 40 of the opening / closing body 4, which is configured by attaching the engaging means 7 to the mounting surface 42a of the widthwise end 40 of the opening / closing body 4, can be suppressed, and the effect of preventing the widthwise end 40 of the opening / closing body 4 from coming off the guide rail 5 can be improved.

[0059] Embodiment 5 Configurations for improving the adhesion between one plate surface 7E and the reference surface 42c include a configuration in which one plate surface 7E is formed as a true curved surface, as in embodiment 2, and a configuration in which a plate such as a metal plate (not shown) is provided in the gap between the curved reference surface 42c and the plane of one plate surface 7E opposite the reference surface 42c.

[0060] For example, in the configuration shown in Figure 3(b), a plate not shown in the figure may be provided to fill the gap G between the reference plane 7m of one plate surface 7E and the reference surface 42c, or in the configuration shown in Figures 9 and 10(b), a plate not shown in the figure may be provided to fill the gap G between the one plate surface 7E, which is a flat surface 7P, and the reference surface 42c, which is a curved surface. In this case, the plate may be attached in advance to the reference plane 7m or one plate surface 7E using an adhesive or the like, or may be attached to the reference surface 42c or 42w. According to embodiment 4, deformation of the widthwise end 40 of the opening / closing body 4, which is configured by attaching the engaging means 7 to the mounting surface 42a of the widthwise end 40 of the opening / closing body 4, can be suppressed, thereby improving the effectiveness of preventing the widthwise end 40 of the opening / closing body 4 from slipping off the guide rail 5.

[0061] In other words, by forming one of the plate surfaces of the engaging means into a non-planar surface corresponding to the curved surface that forms the reference surface 42c, in order to increase the adhesion between the one plate surface and the reference surface 42c, it is configured, for example, as follows. The mounting portion of the engaging means is formed from a base plate having a flat surface extending along the opening / closing direction V (for example, the mounting plate portion 7X shown in Figure 3(b) or the mounting plate portion 7X shown in Figures 9 and 10(b)), and a plate having a true curved surface that matches the curved surface that forms the reference surface 42c along the curved surface that forms the reference surface 42c and a flat surface opposite to the true curved surface (for example, a plate formed with a cross-sectional shape that fills the gap G between the reference plane 7m and the reference surface 42c shown in Figure 3(b), or a plate formed with a cross-sectional shape that fills the gap G between one plate surface 7E and the reference surface 42w or the reference surface 42c shown in Figures 9 and 10(b)), so that one plate surface in the mounting portion of the engaging means is a true curved surface of the plate formed by the flat surface of the base plate and the flat surface of the plate being connected through surface contact. In this way, the adhesion between one plate surface and the reference surface 42c can be improved, thereby suppressing deformation of the widthwise end 40 of the opening / closing body 4, which is configured by attaching the engaging means 7 to the mounting surface 42a of the widthwise end 40 of the opening / closing body 4, and improving the effectiveness of preventing the widthwise end 40 of the opening / closing body 4 from slipping off the guide rail 5.

[0062] In the first and third embodiments, the locked means 7 is exemplified as having the locked recess 7a on the locked surface 7A, but the locked recess 7a may be omitted.

[0063] In each embodiment, the reference surface that constitutes part of the mounting surface of the widthwise end of the opening / closing body is provided with a curved surface or an uneven surface, but the reference surface may be any surface. For example, it may be a flat surface along the opening / closing direction V. That is, in the present invention, it is sufficient that both ends of the mounting portion of the locked means along the opening and closing direction are mounted on the end side wall surfaces.

[0064] Furthermore, each end side wall surface (i.e., the upper end side wall surface and the lower end side wall surface facing each other above and below in the opening / closing direction V) 42b, 42b may be formed as wall surfaces that extend from both end sides of the reference surfaces 42c, 42w in the opening / closing direction V in a direction that intersects with the reference surfaces 42c, 42w and face each other above and below, but preferably they are not formed as wall surfaces that face each other parallel to each other above and below, but as shown in Figures 3(b), 9 and 10, so as to be formed as wall surfaces that extend slightly away from each other from both end sides of the reference surfaces 42c, 42w in the opening / closing direction V.

[0065] In addition, the locking means 6 may be formed by the corner of a flat plate such as a flat bar provided on one side wall of a guide rail having a U-shaped cross section so as to be continuous in the opening and closing direction V of the opening and closing body 4.

[0066] The configuration of the opening / closing body (shutter curtain) of the opening / closing device (shutter device) to which the present invention is applicable is not limited to a configuration in which a plurality of so-called slats are arranged in the opening / closing direction, but may also include an opening / closing body formed by one or more pipes, panels, sheet-like objects, or net-like objects arranged in series, or an opening / closing body formed by an appropriate combination of slats, panels, pipes, sheet-like objects, and net-like objects.The present invention can also be applied to so-called overhead type opening / closing bodies.
