[0014] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. Note that the following embodiment is one form for embodying the present invention, and is not intended to limit the scope of the present invention.

[0015] <Embodiment 1> FIG. 1 is a conceptual diagram of a switching device according to the first embodiment, in which FIG. 1(a) is a conceptual diagram of a vertical cross section, and FIG. 1(b) is a conceptual diagram of a horizontal cross section. The opening / closing device 1 of this embodiment is an opening / closing device (shutter) that opens and closes an opening formed on a wall surface (for example, a garage) that separates the indoors from the outdoors. Hereinafter, the direction from the outdoors to the indoors (the left-right direction in FIG. 1(a)) is referred to as the "depth direction", and the width direction of the opening (the left-right direction in FIG. 1(b)) is simply referred to as the "width direction". In addition, the surface that is the inside of the width direction of the opening when each component is installed (for example, the left side surface of the wiring rail 14 on the right side in FIG. 1(b)) is referred to as the "inner side", and the surface that is the outside (for example, the right side surface of the wiring rail 14 on the right side in FIG. 1(b)) is referred to as the "outer side". In addition, the surface that is the indoor side in the depth direction when each component is installed (for example, the lower surface of the wiring rail 14 in FIG. 1(b)) is referred to as the "indoor side", and the surface that is the outdoor side (for example, the upper surface of the wiring rail 14 in FIG. 1(b)) is referred to as the "outdoor side".

[0016] The opening and closing device 1 of this embodiment is, A shutter curtain 11 that is an opening / closing body for opening and closing the opening and is composed of a plurality of slats; A guide rail 12 that guides the opening and closing movement (up and down sliding) of the shutter curtain 11; a guide rail installation member 13 provided between a wall surface or the like beside the opening and the guide rail 12, for fixing the guide rail 12 to the wall surface or the like; a wiring rail 14 attached to a surface of the guide rail 12 opposite to a surface to which the guide rail installation member 13 is attached; A winding mechanism 20 that opens and closes (winds) the shutter curtain 11; An automatic opening / closing unit (not shown) including a motor and the like for driving the winding mechanism 20; A manual switching device 17 for switching between automatic and manual operation of the automatic opening / closing unit; A transmission member 18 connected to the manual switching device 17 for transmitting a switching operation; A shutter case 19 that houses a winding mechanism 20 and an automatic opening / closing unit therein; It is equipped with: The switching between automatic (electric) and manual opening and closing operation by the automatic opening and closing unit is performed by providing a clutch mechanism in a mechanism (such as a reducer) that transmits the rotational driving force of the automatic opening and closing unit to the winding mechanism 20, and when the transmission member 18 is pulled, the clutch is released and the operation is switched to manual. The manual switching device 17 is a device for pulling the transmission member 18. In addition, as for the shutter curtain 11, winding mechanism 20, automatic opening and closing unit, and other general components of the shutter in the opening and closing device 1 that are not specifically shown here, they are not directly related to the present invention, so further explanation will be omitted here and the following explanation will mainly focus on the components related to the present invention.

[0017] Figures 2 and 3 are diagrams showing the guide rail 12, guide rail installation member 13, and wiring rail 14 (and wiring rail cover 15) of the opening and closing device 1 of this embodiment as an integrated whole, with Figure 2 being an oblique view, Figure 3(a) being a plan view of the inner side (the right side of the figure is the upper side when installed, and the left side is the lower side when installed), Figure 3(b) being a plan view of the indoor side (the right side of the figure is the upper side when installed, and the left side is the lower side when installed, with the internal structure (manual switching device 17) shown transparently to make it easier to understand), and Figure 3(c) being a horizontal cross-sectional view. Note that, below, the configuration of the side on which the manual switching device 17 is installed (one side of the left or right rail member) will be described, but the guide rail, guide rail installation member, wiring rail (and wiring rail cover) on the other side are basically similar components that are symmetrical on the left and right (since manual switching device 17 is not installed on the other side, there is no manual switching device 17 described below or the configuration for installing it).

[0018] The guide rail 12 is a member having a substantially U-shaped opening in cross section, which receives both ends of the shutter curtain 11 from the opening and guides the up-down sliding movement of the shutter curtain 11. The guide rail 12 itself is conceptually similar to conventional guide rails, so further explanation will be omitted here.

[0019] The guide rail installation member 13 is a member for fixing the guide rail 12 to a structure such as a wall surface beside an opening, and as shown in Figure 2, extends in the vertical direction along the guide rail 12 for approximately the same length as the guide rail 12. As shown in Figure 3(c), the guide rail installation member 13 is a tubular member with a rectangular cross-section formed by diagonally arranging (joining) a guide rail mounting member 131a having an approximately L-shaped cross-section and a guide rail receiving member 131b having an approximately L-shaped cross-section. The guide rail attachment member 131a is fixed (riveted) to the guide rail 12, and the guide rail receiving member 131b is fixed (screwed) to a structure such as a wall surface beside the opening. The guide rail 12 is installed by attaching (screw-fastening) a guide rail attachment member 131a to which the guide rail 12 is fixed to a guide rail receiving member 131b that is fixed to a structure. In this embodiment, the guide rail mounting member 131a and the guide rail receiving member 131b are made to be the same member to achieve standardization of parts, but the guide rail mounting member 131a and the guide rail receiving member 131b may be different members.

[0020] The wiring rail 14 is a wiring rail for passing wiring for sensors (e.g., photoelectric sensors for detecting the presence of people) and the like, and is also a component to which the manual switching device 17 is attached and in which the transmission member 18 is arranged. The opening and closing device 1 of this embodiment is a so-called "inward roll" type in which a shutter case 19 is provided on the indoor side (see FIG. 1). From the viewpoint of security, it is preferable that a manual switching device 17 for switching between automatic and manual be installed indoors rather than on the shutter curtain 11. Therefore, the manual switching device 17 is installed on a wiring rail 14 provided on the indoor side of a guide rail 12. As shown in FIG. 2, the wiring rail 14 extends for approximately the same length as the guide rail 12 (more specifically, the length from the ground to the shutter case 19) and is a "guide rail side component extending along the guide rail and attached to the guide rail directly or via another component."

[0021] Fig. 4 shows the wiring rail 14 (with the manual switching device 17 attached), with Fig. 4(a) being a perspective view, Fig. 4(b) being a plan view of the inner side (the right side of the figure is the upper side when installed, and the left side is the lower side when installed), and Fig. 4(c) being a plan view of the indoor side. Fig. 4(d) is a perspective view showing the wiring rail 14 without the manual switching device 17 attached. The wiring rail 14 of the present embodiment is made of steel and is a member having an approximately U-shaped cross section having an inner side 141, an outdoor side 142, and an outer side 143. A bent portion 144 formed on the indoor side of the outer side 143 is a bent portion for improving the strength and rigidity of the wiring rail 14. The inner surface 141 is formed with a notch 1411 and a notch 1412, and the bent portion 144 is formed with a notch 1441. The notch 1411 is an attachment portion for attaching the manual switching device 17, and is cut out so as to reach from the inner side surface 141 to the outdoor side surface 142. The notch 1411 in the inner side surface 141 is formed so as to accommodate the main body portion 173 of the manual switching device 17, while the inner side surface 141 is present (so as to be screwed) at a position facing the attachment plate portion 171 of the manual switching device 17. By forming the notch 1411 so as to reach the outdoor side surface 142, the manual switching device 17 can be disposed as close as possible to the guide rail 12 side (outdoor side), which allows for effective use of space and miniaturization of parts (reducing the dimension in the depth direction of the wiring rail 14). The manual switching device 17 is a so-called "French drop" and has a mechanism in the main body 173 that converts the lifting motion of the lever 175 into a vertical motion (horizontal motion in FIG. 4(c)). This vertically converted motion moves the parallel moving member 1721 in the vertical direction. A wire locking metal fitting 172 for locking the wire 182 of the transmission member 18 is connected to the parallel moving member 1721. A fixing metal fitting 174 for fixing the outer tube 181 of the transmission member 18 is attached to the inner surface of the wiring rail 14. The outer tube 181 of the transmission member 18 is fixed to the fixing metal fitting 174 and the wire 182 is connected to the wire locking metal fitting 172, so that the wire locking metal fitting 172 moves downward by lifting the lever 175, and the wire 182 is also pulled downward, and the opening and closing operation by the automatic opening and closing unit is switched to manual (the clutch of the clutch mechanism described above is disengaged). The notch 1441 formed in the bent portion 144 is a relief portion provided so that the bent portion 144 does not interfere with the operation of the manual switching device 17 (the parallel moving member 1721, the wire locking metal fitting 172, etc.). This makes effective use of a small space while keeping the range of the notch to a minimum (only the range where there is a risk of interference between members), thereby keeping the strength and rigidity of the wiring rail 14 within an allowable range. In addition, the presence of the notch 1441 provides a working space for attaching and detaching the transmission member 18 to and from the manual switching device 17 (for example, the rotation angle of a wrench can be increased), improving workability.

[0022] The width dimension of the wiring rail 14 (guide rail side member) is formed smaller than the width dimension of the guide rail 12 by at least the thickness of the mounting plate portion 171 of the manual switching device 17. This makes it possible to make the outer dimension of the width direction of the wiring rail 14 to which the manual switching device 17 is attached equal to or smaller than the width direction dimension of the guide rail 12 (i.e., the occurrence of protruding parts is prevented). The manual switching device 17 is attached to the inner surface of the wiring rail 14 (guide rail side member), so it is easily accessible to the user, and since it does not protrude from the guide rail 12, it does not get in the way and has excellent design.

[0023] The notch 1412 formed in the inner surface 141 of the wiring rail 14 is a notch formed to receive the wiring of a sensor (such as a photoelectric sensor) attached to the wiring rail cover 15 when the wiring rail cover 15 is attached to the wiring rail 14. Therefore, the notch 1412 is formed at a location facing the position where the sensor of the wiring rail cover 15 is attached, and also, a notch opening is formed on the side where the wiring rail cover 15 is attached.

[0024] FIG. 5 is a perspective view showing the wiring rail cover 15. As shown in FIG. The wiring rail cover 15 is a component for covering the wiring rail 14, and together with the wiring rail 14, it also functions as a wiring rail for passing sensor wiring, etc., and for installing sensors, and is also a component that forms the main design surface on the indoor side. The wiring rail cover 15 of this embodiment is made of steel and is a member having an approximately U-shaped cross section having an inner side 151, an indoor side 152, and an outer side 153. A bent portion 154 formed on the outdoor side of the outer side 153 is a bent portion for improving the strength and rigidity of the wiring rail cover 15, and is bent into a crank shape to prevent a gap from being generated when the wiring rail cover 15 engages with the bent portion 144 of the outer side 143 of the wiring rail 14 (see FIG. 3(c)). The inner surface 151 is formed with a notch 1511 and a sensor mounting hole 1512 . The notch 1511 is a notch formed for receiving the manual switching device 17 attached to the wiring rail 14 when the wiring rail cover 15 is attached to the wiring rail 14. The notch 1511 is formed at a size and position capable of receiving the outer diameter shape of the operation surface side including the mounting plate portion 171 of the manual switching device 17. The sensor mounting hole 1512 is a hole in which a photoelectric sensor is mounted. The notch 1541 formed in the bent portion 154 is a relief portion provided so that the bent portion 154 does not interfere with the operation of the manual switching device 17 (the parallel moving member 1721, the wire locking fitting 172, etc.), similar to the notch 1441 of the wiring rail 14. This makes it possible to effectively utilize a small space while keeping the range of the notch to a minimum (only the range where there is a risk of interference with members), thereby keeping the strength and rigidity of the wiring rail cover 15 within an allowable range.

[0025] FIG. 6 is an explanatory diagram (a horizontal cross-sectional view) relating to the assembly of the guide rail 12, the guide rail installation member 13, and the wiring rail 14. As shown in FIG. First, the guide rail receiving member 131b is screwed to the frame or the like, and the guide rail mounting member 131a and the wiring rail 14 are riveted to the guide rail 12. The manual switching device 17 is screwed to the wiring rail 14. Next, the guide rail mounting member 131a, which is integrated with the guide rail 12 and the wiring rail 14, is attached to the guide rail receiving member 131b fixed to the frame by sliding it from the inside to the outside in the width direction, and then screwed in. In this state, the transmission member 18 is attached to the manual switching device 17. This attachment is performed by attaching the outer tube 181 of the transmission member 18 to the fixing metal fitting 174 and attaching the wire 182 to the wire locking metal fitting 172. Then, the wiring rail cover 15 with the photoelectric sensor attached in the sensor attachment hole 1512 is attached to the wiring rail 14 by sliding it from the indoor side to the outdoor side, and then screwed in. At this time, as described above, the notch 1412 is formed in the wiring rail 14, so that the wiring rail cover 15 with the photoelectric sensor attached in advance can be slid and attached.

[0026] As described above, according to the opening and closing device 1 of this embodiment, the manual switching device 17 is attached to the inner surface of the wiring rail 14 (guide rail side member), making it easy for the user to access, and since there is no protrusion from the guide rail 12, it does not get in the way and has excellent design. The wiring rail 14 of this embodiment is formed by bending a steel plate material, and it is difficult from the viewpoint of economy, etc. to form a stepped recess (a recess for receiving the mounting plate portion 171 of the manual switching device 17) only in a part of the side surface. Therefore, a step corresponding to the plate thickness of the mounting plate portion 171 is generated on the surface of the wiring rail 14, but the above configuration can eliminate protrusions from the guide rail 12 (reduction of protrusions as an integral structure), so that it is possible to prevent people or objects from being injured or damaged by bumping into (getting caught on) the protrusions.

[0027] <Embodiment 2> FIG. 7 is a conceptual diagram of a switching device according to the second embodiment, where FIG. 7(a) is a conceptual diagram of a vertical cross section, and FIG. 7(b) is a conceptual diagram of a horizontal cross section. The opening and closing device 1-2 of this embodiment is also a shutter device like that of embodiment 1, but it is a so-called "external wrap" type in which the shutter case 19 is provided on the outdoor side, and therefore differs from embodiment 1 in that the guide rail installation member 16 also functions as a wiring rail. Note that the same reference numerals as in the first embodiment are used for the components having the same concept as in the first embodiment, and the description thereof will be simplified or omitted.

[0028] Figures 8 and 9 are diagrams showing the guide rail 12 and guide rail installation member 16 of the opening and closing device 1-2 of this embodiment as an integrated unit, with Fig. 8 being an oblique view, Fig. 9(a) being a plan view of the inner side (the right side of the figure is the upper side when installed, and the left side is the lower side when installed), Fig. 9(b) being a plan view of the indoor side (the right side of the figure is the upper side when installed, and the left side is the lower side when installed, with the internal structure (manual switching device 17) shown transparently to make it easier to understand), and Fig. 9(c) being a horizontal cross-sectional view. As in embodiment 1, the configuration of the side on which manual switching device 17 is provided (one of the left and right rail members) will be described, but the guide rail and guide rail installation member on the other side are basically similar, symmetrical members (since manual switching device 17 is not provided on the other side, there is no manual switching device 17 described below or the configuration for installing it).

[0029] The guide rail installation member 16 is a member for fixing the guide rail 12 to a structure such as a wall surface beside an opening, and as shown in Figure 8, extends in the vertical direction along the guide rail 12 for approximately the same length as the guide rail 12. The guide rail installation member 16 is composed of a guide rail attachment member 162 and a guide rail receiving member 161, and is a cylindrical member with a rectangular cross section when the guide rail attachment member 162 and the guide rail receiving member 161 are assembled.

[0030] The guide rail receiving member 161 is a member that is fixed (screwed) to a structure such as a wall surface beside the opening, and is also a member to which the manual switching device 17 is attached. The guide rail receiving member 161 extends over approximately the same length as the guide rail 12, and is a "guide rail side member that extends along the guide rail and is attached to the guide rail directly or via another member." Fig. 10 shows the guide rail receiving member 161 (with the manual switching device 17 attached), with Fig. 10(a) being a perspective view, Fig. 10(b) being a plan view of the inner side (the right side of the figure is the upper side when installed, and the left side is the lower side when installed), and Fig. 10(c) being a plan view of the outdoor side (the right side of the figure is the upper side when installed, and the left side is the lower side when installed). Fig. 10(d) is a perspective view showing the guide rail receiving member 161 without the manual switching device 17 attached. The guide rail receiving member 161 of this embodiment is made of steel and has an inner side 1611, an indoor side 1612, and an outer side 1613. The bent portion 1614 formed on the outdoor side of the outer side 1613 is a bent portion for improving the strength and rigidity of the guide rail receiving member 161. The inner surface 1611 is formed with a notch 16111 and a notch 16112, and the bent portion 1614 is formed with a notch 16141. The notch 16111 is an attachment portion for attaching the manual switching device 17. The notch 16111 of the inner surface 1611 is formed so as to accommodate the main body portion 173 of the manual switching device 17, while the inner surface 1611 is present at a position facing the attachment plate portion 171 of the manual switching device 17 (so that it can be screwed). The wire locking metal fitting 172 and the fixing metal fitting 174 for connecting the manual switching device 17 and the transmission member 18 are the same as those in the first embodiment. The notch 16141 formed in the bent portion 1614 is a relief portion provided so that the bent portion 1614 does not interfere with the operation of the manual switching device 17 (the parallel moving member 1721, the wire locking metal fitting 172, etc.). This makes it possible to effectively utilize a small space while keeping the range of the notch to a minimum (only the range where there is a risk of interference between members), thereby keeping the strength and rigidity of the guide rail receiving member 161 within an allowable range. Also, like the notch 1441 in the first embodiment, the notch 16141 forms a working space for the attachment and detachment of the transmission member 18 to and from the manual switching device 17, improving workability.

[0031] The width dimension of the guide rail receiving member 161 (guide rail side member) is formed smaller than the width dimension of the guide rail 12 by at least the thickness of the mounting plate portion 171 of the manual switching device 17. This makes it possible to make the outer width dimension of the guide rail receiving member 161 to which the manual switching device 17 is attached equal to or smaller than the width dimension of the guide rail 12 (i.e., to prevent the occurrence of protruding parts).

[0032] The notch 16112 formed in the inner surface 1611 of the guide rail receiving member 161 is a notch formed for receiving wiring of a sensor (such as a photoelectric sensor) attached to the guide rail mounting member 162 when the guide rail mounting member 162 is attached to the guide rail receiving member 161. Therefore, the notch 16112 is formed at a location facing the position where the sensor of the guide rail mounting member 162 is attached, and an opening of the notch is formed on the side where the guide rail mounting member 162 is attached.

[0033] The guide rail mounting member 162 is fixed to the guide rail 12, and the guide rail 12 is installed by attaching (screw-fastening) the guide rail mounting member 162 to which the guide rail 12 is fixed to a guide rail receiving member 161 fixed to a structure. The guide rail mounting member 162 also functions as a wiring rail for passing sensor wiring and the like together with the guide rail receiving member 161, and also functions to install the sensor. FIG. 11 is a perspective view showing the guide rail mounting member 162. As shown in FIG. The guide rail mounting member 162 of this embodiment is made of steel and has an inner side 1621, an outdoor side 1622, and an outer side 1633, and the basic aspect of the cross section is a substantially U-shaped member. The bent portion 1624 formed on the indoor side of the outer side 1623 is a bent portion for improving the strength and rigidity of the guide rail mounting member 162, and is bent into a crank shape to prevent a gap from being generated when the guide rail mounting member 162 engages with the bent portion 1614 of the outer side 1613 of the guide rail receiving member 161 (see FIG. 9(c)). The inner surface 1621 is formed with a notch 16211 and a sensor mounting hole 16212 . The notch 16211 is a notch formed in order to receive the manual switching device 17 attached to the guide rail receiving member 161 when the guide rail mounting member 162 is attached to the guide rail receiving member 161. The notch 16211 is formed at a size and position capable of receiving the outer diameter shape of the operation surface side including the mounting plate portion 171 of the manual switching device 17. The sensor mounting hole 16212 is a hole in which a photoelectric sensor is mounted. The notch 16241 formed in the bent portion 1624 is a relief portion provided so that the bent portion 1624 does not interfere with the operation of the manual switching device 17 (the parallel moving member 1721, the wire locking metal fitting 172, etc.), similar to the notch 16141 of the guide rail receiving member 161. This makes it possible to effectively utilize a small space while keeping the range of the notch to a minimum (only the range where there is a risk of interference with members), thereby keeping the strength and rigidity of the guide rail mounting member 162 within an allowable range.

[0034] As described above, according to the opening and closing device 1-2 of this embodiment, similarly to the first embodiment, it is easy for the user to access, and since it does not protrude from the guide rail 12, it is not in the way and has excellent design. Furthermore, the guide rail installation member 16 also functions as a wiring rail, making it possible to reduce the number of parts, thereby lowering costs and simplifying the assembly work. In addition, the workability is also excellent in the work of replacing the guide rail 12 when the guide rail 12 is damaged. In the configuration of embodiment 1, the work of replacing the guide rail 12, etc., requires the removal (and installation) of the wiring rail 14 to which the manual switching device 17 is attached. At this time, the work of attaching and detaching the transmission member 18 to the manual switching device 17 is also required. In contrast, according to the opening and closing device 1-2 of this embodiment, the work of replacing the guide rail 12 does not require the removal of the guide rail receiving member 161 to which the manual switching device 17 is attached, and therefore, excellent workability is achieved.
