Description

[Technical Field]

[0001] The present invention relates to an opening / closing device or the like that has a function of preventing the widthwise ends of an opening / closing body from slipping off guide rails. [Background technology]

[0002] An opening and closing device is known which includes a guide rail having guide grooves that guide the left and right widthwise ends of an opening and closing body that opens and closes an opening along the opening and closing direction of the opening and closing body, a locking means provided in the guide groove of the guide rail, and a lockable means provided at the left and right widthwise ends of the opening and closing body, and which is configured so that the lockable means locks onto the locking means to prevent the widthwise ends of the opening and closing body from slipping out of the guide grooves (see Patent Document 1).

[0003] [Patent Document 1] Japanese Patent Application Publication No. 2023-89532 Summary of the Invention [Problem to be solved by the invention]

[0004] In the above-described conventional opening and closing device, the locking means provided in the guide groove of the guide rail is formed by a corner portion extending along the extension direction of the guide rail on the inside of the guide rail. That is, a part of the guide rail is configured to function as a locking means. Conventionally, for example, when the opening width of the opening where the opening / closing device is installed is large, and a high-strength opening / closing body made of thick plates is used to improve wind pressure resistance, it is preferable that the locking means of the guide rail also be made high in strength to match the strength of the opening / closing body. However, when using a guide rail in which a part of the guide rail functions as a locking means as described above, guide rails of different strengths are required depending on the strength of the opening / closing body. In other words, in the past, in opening and closing devices that have a function to prevent the widthwise end of the opening and closing body from slipping out of the guide rail, there was a problem that when the strength of the opening and closing body was changed according to, for example, the opening width of the opening, guide rails of different strengths were required depending on the strength of the opening and closing body used.

[0005] In order to solve the above problems, the present invention provides an opening and closing device having a function to prevent the widthwise end of the opening and closing body from slipping out of the guide rail, which allows the locking means attached to the guide rail to be changed to match the strength of the opening and closing body, and which has a highly versatile guide rail to which locking means of various strengths can be attached to match the strength of the opening and closing body to be used.

[0008] Embodiment 1 As shown in FIG. 1, an opening / closing device (shutter device) 1 according to the first embodiment includes an opening / closing body 2, a winding device 3 for the opening / closing body 2, a shutter case 4, and a guide rail 5. Hereinafter, in this specification, up, down, left, right, front, and rear will be defined as directions shown in FIGS. In the cross-sectional view of FIG. 2, cross-sectional hatching is omitted.

[0009] The opening / closing body 2 comprises an opening / closing body main body 20 and an other end component member 21 provided at the other end (lower end) of the opening / closing body main body 20, and is configured such that one end (upper end) is connected to the rotating body 30 of the winding device 3 via a connecting member called a hanging point (not shown), for example, to open and close an opening 10 formed in an architectural structure, etc. The opening / closing body 2 is called, for example, a shutter curtain. The opening / closing body main body 20 is called, for example, a slat curtain. The other end component 21 is called, for example, a seat plate or a water drain. The term "architectural structure" refers to buildings such as detached houses, apartment buildings, buildings, warehouses, factories, and the like, as well as exterior structures such as garages, carports, gates, and fences, and structures such as tunnels and underground shopping malls.

[0010] The opening / closing body main body 20 is formed by connecting a plurality of slats 25, 25 . Each slat 25 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-right width direction (left-right direction) W (see Figure 1) of the opening 10 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 4, each slat 25 is configured to have a slat panel portion 26 that forms a slat surface that is slightly curved along the short side direction (opening / closing direction (up and down direction) V (see Figure 1)), and connecting means provided on both ends of the slat panel portion 26 in the short side direction. The connection between the slats 25 is achieved by connecting the connection means of one slat 25 to the connection means of the other slat 25 to be connected. The connecting means is constituted by curled portions 27, 27 provided along one long side edge and the other long side edge of each slat 25 and formed into a shape that allows them to be locked together.

[0011] The winding device 3 is a device that winds up the opening / closing body 2 for opening and closing the opening 10 described above. The winding device 3 is configured to include a rotating body 30 that winds up the opening / closing body 2, and a rotational force applying means (not shown) that applies a rotational force to the rotating body 30.

[0012] As shown in FIG. 1, the left end 30L of the rotor 30 of the winding device 3 is attached to a left bracket 40L, and the right end 30R of the rotor 30 of the winding device 3 is attached to a right bracket 40R. The left bracket 40L and the right bracket 40R are attached to the body 11 located above the opening 10, for example. One end of the opening / closing body 2 is connected to the rotating body 30 via a hanging point, and the rotating body 30 is configured to rotate around the central axis 30C of the rotating body 30 as the center of rotation by a rotational force imparting means, thereby forming an opening / closing device 1 that can open and close the opening 10 using the opening / closing body 2.

[0013] In the case of an electric type, the rotational force imparting means is composed of a motor (not shown) as a driving source that rotates the rotating body 30 in the winding direction of the opening / closing body 2 and the unwinding direction of the opening / closing body 2, and a power transmission mechanism such as gears or belts (not shown) that transmits the rotational force of the motor to the rotating body 30. In the case of a manual type, the rotational force applying means is constituted by a spring or the like for rotating the rotating body 30 in the winding direction of the opening / closing body 2. The rotational force applying means may be configured to use a drive source and a spring in combination.

[0014] The shutter case 4 is a case for accommodating the winding device 3 and the opening / closing body 2 wound up by the winding device 3, and is attached to a body 11 located above the opening 10, for example.

[0015] The left and right guide rails 5, 5 are installed, for example, on a main body 11 positioned on the left and right sides of the opening 10, and are configured to have guide grooves 5a that guide the left and right ends 22, 22 of the opening / closing body 2 in the width direction (left-right direction) W along the opening / closing direction (up-down direction) V of the opening / closing body 2.

[0016] The opening / closing body 2 of the opening / closing device 1 configured as described above is wound onto the rotating body 30 of the winding device 3 to open the opening 10 of the building structure, and the opening / closing body 2 is unwound (rolled out) from the rotating body 30 of the winding device 3 to close the opening 10.

[0017] As shown in Figure 2(a), 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 at the left and right widthwise ends 22, 22 of the opening and closing body 2 to lock onto the locking means 6 and prevent the widthwise ends 22 of the opening and closing body 2 from slipping out of the guide grooves 5a. In other words, the opening and closing device 1 is configured so that the engaging means 7 provided on the left and right widthwise end portions 22 of the opening and closing body 2 engage with the engaging means 6 provided in the guide grooves 5a of the left and right guide rails 5, thereby preventing the widthwise end portions 22 of the opening and closing body 2 from slipping out of the guide grooves 5a.

[0018] In the opening and closing device 1 according to the first embodiment, as shown in FIG. 3, the locking means 6 and the guide rail 5 are configured as separate components. That is, a locking means mounting portion 8 is formed in the guide groove 5a of the guide rail 5, and the locking means 6, which is a separate part from the guide rail 5, is attached to the locking means mounting portion 8, thereby forming a guide rail equipped with the locking means 6 as shown in Figure 2.

[0019] The locking means 6 is composed of an elongated member that is long in the direction along the extension direction of the guide rail 5 (the vertical direction (opening / closing direction) V in FIG. 1, the direction perpendicular to the paper surface of FIG. 2). As shown in Figure 3, the locking means 6 is composed of a long member having a base plate 60 that is long in the direction along the extension direction of the guide rail 5, a locking portion 61 formed to protrude from one plate surface 60a of the base plate 60, an attachment guide portion 62 formed to protrude from the other plate surface 60b of the base plate 60, and an attachment portion that is attached to the locking means attachment portion 8. The locking portion 61 is formed on one plate surface 60a of the substrate 60 so as to be continuous between one end side and the other end side in the extension direction (longitudinal direction) of the plate surface 60a. The mounting guided portion 62 is formed on the other plate surface 60b of the substrate 60 so as to be continuous between one end side and the other end side in the extension direction (longitudinal direction) of the plate surface 60b.

[0020] As shown in Figure 3, the locking means 6 is configured to have a mounting portion to be attached to the locking means mounting portion 8, which is a one-side mounting portion 60x formed by one edge side portion along the longitudinal direction (extension direction) of the substrate 60, and an other-side mounting portion 60y formed by the other edge side along the longitudinal direction of the substrate 60. In other words, the long edge portion located at one end of the short side of the locking means 6, which is a direction perpendicular to the longitudinal direction of the base plate 60, functions as the one-side mounting portion 60x, and the long edge portion located at the other end of the short side of the locking means 6, which is a direction perpendicular to the longitudinal direction of the base plate 60, functions as the other-side mounting portion 60y. That is, the one-side mounted portion 60x and the other-side mounted portion 60y constitute the mounted portion of the locking means 6 that is mounted to the locking means mounting portion 8.

[0021] The locking means mounting portion 8 comprises a one-side mounting portion 81 into which one-side mounting portion 60x of the base plate 60 of the locking means 6 is inserted and mounted, an other-side mounting portion 82 into which the other-side mounting portion 60y of the base plate 60 of the locking means 6 is inserted and mounted, and a mounting guide groove 83.

[0022] The one-side mounting portion 81, the other-side mounting portion 82, and the mounting guide groove 83 are formed so as to be continuous, for example, between one end side and the other end side of the extension direction (longitudinal direction) of the guide rail 5. The one-side mounting portion 81 is configured as a groove with a concave cross section into which the flat one-side mounting portion 60x is inserted and mounted. The other-side mounting portion 82 is configured as a groove with a concave cross section into which the flat plate-shaped other-side mounted portion 60y is inserted and mounted. The mounting guide groove 83 is configured as a groove having a cross-sectional shape corresponding to the cross-sectional shape of the mounting guided portion 62 .

[0023] The guide rail 5 and the locking means 6 are made of long members extending along the vertical direction (opening / closing direction) V, and are manufactured, for example, by roll forming so that the lengths in the long direction are approximately the same. The materials constituting the guide rail 5 and the locking means 6 are not particularly limited, but the guide rail 5 is made of, for example, metal, and the locking means 6 is made of, for example, synthetic resin or metal.

[0024] The method of attaching the locking means 6 to the locking means attachment portion 8 of the guide rail 5 is, for example, as shown in Figure 3, by inserting the locking means 6 from one longitudinal side 6E of the locking means 6 into the locking means attachment portion 8 through an opening on the other longitudinal side 5S of the locking means attachment portion 8 of the guide rail 5. In other words, the one-side mounting portion 60x, the other-side mounting portion 60y, and the mounting guide portion 62 on one 6E side of the longitudinal direction of the locking means 6 are inserted through the openings on the other side of the one-side mounting portion 81, mounting guide groove 83, and other-side mounting portion 82 on the other 5S side of the longitudinal direction of the locking means mounting portion 8 of the guide rail 5, and after the one 6E side of the longitudinal direction of the locking means 6 is moved to one side of the longitudinal direction of the locking means mounting portion 8 of the guide rail 5, the locking means 6 is fixed to the locking means mounting portion 8. The method for fixing the locking means 6 to the locking means attachment portion 8 is not particularly limited, but may be, for example, by using a fixing method such as caulking, welding, or a fastening material. As a result, the guide rail 5 is constructed, in which the locking means 6 is attached to the locking means attachment portion 8 formed in the guide groove 5a.

[0025] When the locking means 6 is attached to the locking means attachment portion 8 of the guide rail 5, the attachment guided portion 62 is guided by the attachment guide groove 83, so that the attachment work can be carried out easily and reliably. Furthermore, the mounting guide portion 62 also functions as a reinforcing portion for increasing the strength of the locking means 6, making it possible to provide a locking means 6 with high strength.

[0026] Furthermore, the locking means 6 can be configured so that the one-side mounting portion 60x and the other-side mounting portion 60y are the same, but the size and strength of the locking portion 61 are different, and the one-side mounting portion 60x and the other-side mounting portion 60y can be attached to the one-side mounting portion 81 and the other-side mounting portion 82.

[0027] As shown in Figures 4 to 8, the engaging means 7 is composed of an attachment plate portion 70 attached to the slat face plate portion 26 on the widthwise end portion 22 side of the slat 25 constituting the opening / closing body 2, an extension plate portion 71 extending from the side edge of the attachment plate portion 70, an engaging plate portion 72 extending from the extended end side of the extension plate portion 71 in a direction intersecting with the plate surface of the extension plate portion 71, and an engaging groove 73 formed on the plate surface of the engaging plate portion 72 on the side closer to the slat 25. The engaging means 7 is attached to the slat face plate 26 by a fixing means such as a rivet 76, such that the extension plate 71 extends outward in the width direction beyond the widthwise edge of the slat 25. For example, the engaging means 7 is fixedly attached to the slat 25 by attaching the rivet 76 to an attachment hole 75 (see FIG. 5) formed in the attachment plate 70 and an attachment hole (not shown) formed in the slat 25.

[0028] As shown in Figure 4(a), the slat panel portion 26 of the slat 25 is formed with a plurality of ribs extending along the longitudinal direction (left-right width direction W) of the slat 25 and aligned in the vertical direction, and an attachment fitting recess 28 is formed by a recess between any adjacent ribs in the vertical direction. As shown in Figures 4(d), 5, and 7, the mounting plate portion 70 and the extension plate portion 71 of the engaging means 7 have mounting engagement protrusions 74 extending in the left-right direction formed on the mounting surface side of the plate surfaces. In other words, the engaging means 7 is attached to the slat 25 in a state in which the mounting engagement protrusion 74 of the engaging means 7 and the mounting engagement recess 28 formed in the slat face plate portion 26 of the slat 25 are engaged, thereby improving the mounting strength of the engaging means 7 to the slat 25.

[0029] In addition, when the mounting plate portion 70 is attached to the slat face plate portion 26, the engaging groove 73 is formed so as to extend in the vertical direction (opening / closing direction) V on the plate surface that is closer to the slat 25 in the engaging plate portion 72. As shown in FIGS. 4(c), 6(c), and 8, the locked groove 73 is formed, for example, by a groove having a triangular cross section.

[0030] The latching means 7 may be provided on all of the slats 25, 25, . . . that constitute the opening / closing body main body 20, or may be provided only on any slats 25 that are selected intermittently.

[0031] As shown in Figure 2(a), when the left and right widthwise end portions 22, 22 of the opening / closing body 2 to which the engaging means 7 is attached are positioned within the guide grooves 5a, 5a of the guide rails 5, 5, within the guide groove 5a of the left guide rail 5, the engaging groove 73 of the engaging means 7 is positioned to the left of the engaging protrusion 61b of the engaging portion 61 of the engaging means 6 so as to face the engaging protrusion 61b, and within the guide groove 5a of the right guide rail 5, the engaging groove 73 of the engaging means 7 is positioned to the right of the engaging protrusion 61b of the engaging portion 61 of the engaging means 6 so as to face the engaging protrusion 61b.

[0032] For example, when a force such as wind pressure is applied to the front or rear of the opening / closing body 2 that has closed the opening 10, the engaging groove 73 of the engaging means 7 engages with the engaging protrusion 61b of the engaging portion 61 of the engaging means 6, preventing the widthwise end 22 of the opening / closing body 2 from slipping out of the guide groove 5a. That is, in the opening / closing device 1 of embodiment 1, as shown in Figure 2(a), the locking portion 61 of the locking means 6 has a locking protrusion 61b, and the locked means 7 has a locking groove 73, and when a force such as wind pressure is applied to the opening / closing body 2, as shown in Figure 2(b), the locking groove 73 of the locked means 7 engages with the locking protrusion 61b of the locking portion 6, thereby preventing the widthwise end 22 of the opening / closing body 2 from coming off the guide groove 5a. Incidentally, Figure 2(b) shows the state in which the engaging groove 73 of the engaging means 7 engages with the engaging protrusion 61b of the engaging portion 6 when a force such as wind pressure is applied to the front of the opening / closing body 2 that has closed the opening 10. However, even when a force such as wind pressure is applied to the rear of the opening / closing body 2 that has closed the opening 10, the engaging groove 73 of the engaging means 7 similarly engages with the engaging protrusion 61b of the engaging portion 6, thereby preventing the widthwise end 22 of the opening / closing body 2 from slipping out of the guide groove 5a.

[0033] As shown in Figures 2(a) and 3, the guide rail 5 comprises a side plate portion 50 that forms the bottom wall of the guide groove 5a, a front plate portion 51 that extends from the front edge of the side plate portion 50 toward the center of the opening, and a rear plate portion 52 that extends from the rear edge of the side plate portion 50 toward the center of the opening. Cushioning materials 85, 85 are provided on the extended end edges of the front plate portion 51 and the rear plate portion 52, which form the groove opening edges of the guide groove 5a, and these cushioning materials 85, 85 are configured to prevent contact between the surface (front and rear surfaces) of the opening / closing body main body 20 and the groove opening edges of the guide groove 5a, thereby achieving effects such as reducing sliding noise when opening and closing the opening / closing device 2 and preventing scratches on the surface of the opening / closing body main body 20. The buffer material 85 is made of an elastic material such as rubber, or a synthetic resin. The buffer material 85 is provided so as to extend, for example, over the entire extension direction (vertical direction) of the groove opening edge of the guide groove 5a. A cushioning material mounting portion 86 is provided on the extended end edge of the front plate portion 51, which forms the groove opening edge of the guide groove 5a, and is configured to extend over the entire extension direction (up and down direction) of the groove opening edge of the guide groove 5a, and a cushioning material 85 is attached to the cushioning material mounting portion 86.

[0034] In the opening and closing device 1 of the present invention, when the front side in FIG. 2 is the outdoor side, the rear side in FIG. 2 is the indoor side, and when the front side in FIG. 2 is the indoor side, the rear side in FIG. 2 is the outdoor side. Therefore, when the front plate portion 51 of the guide rail 5 described above is the outdoor side plate portion, the rear plate portion 52 of the guide rail 5 is the indoor side plate portion, and when the front plate portion 51 of the guide rail 5 is the indoor side plate portion, the rear plate portion 52 of the guide rail 5 is the outdoor side plate portion.

[0035] According to the opening and closing device 1 of embodiment 1, the opening and closing device 1 is configured so that the engaging means 7 is engaged with the engaging means 6 to prevent the opening and closing body 2 from slipping out of the guide groove 5a at the widthwise end 22 thereof, and is configured to include an engaging means mounting portion 8 formed in the guide groove 5a of the guide rail 5, and an engaging means 6 mounted on the engaging means mounting portion 8. In other words, since the guide rail 5 and the locking means 6 are configured as separate parts, for example, by manufacturing a locking means 6 with the strength of the locking portion 61 designed to match the strength of the opening / closing body 2 to be used, and attaching the locking means 6 corresponding to the strength of the opening / closing body 2 to be used to the locking means mounting portion 8 of the guide rail 5, it is possible to configure an opening / closing device 1 that has a function to prevent the widthwise end 22 of the opening / closing body 2 from coming off the guide rail 5 as described above.

[0036] In other words, the locking means 6 has one-side attached portion 60x and the other-side attached portion 60y of the same configuration, and is configured so that it is easy to manufacture a configuration that includes locking portions 61 with different strengths. In other words, the locking means 6 is configured so that the specifications of the locking portions 61 can be easily changed.
