FIG. DETAILED DESCRIPTION OF THE INVENTION

[0012] As shown in FIG. 1 , the shutter device according to this embodiment includes a shutter curtain 1 that opens and closes an opening, guide rails 2 provided at both widthwise ends of the opening, a winding shaft 3 provided above the opening and around which the shutter curtain 1 is wound, an opening / closing device M provided above the opening toward one side in the widthwise direction of the opening and power-transmittingly connected to the winding shaft 2, a shutter case 4 located above the opening and housing the winding shaft 3, the shutter curtain 1 wound around the winding shaft 3, and the opening / closing device M, and an electric opening / closing operation unit 5 that electrically opens and closes the shutter. In one embodiment, the electric opening / closing operation unit 5 is configured as a switch box embedded in the wall, but the electric opening / closing operation unit 5 may also be a remote control unit 5′. A power supply switching unit 6 is provided in the frame near the opening, and the power supply switching unit 6 can be connected to a portable power source (battery) 7, exemplified as an external power source, via an external power supply cord 8 that supplies power from the external power source.

[0013] 1 to 3, when the open switch of the electric opening / closing operation unit 5 is pressed, an open signal is sent to the shutter control panel 50, which drives the opening / closing machine M to raise the shutter curtain 1; when the close switch of the electric opening / closing operation unit 5 is pressed, a close signal is sent to the shutter control panel 50, which drives the opening / closing machine M to lower the shutter curtain 1; when the stop switch of the electric opening / closing operation unit 5 is pressed, the opening / closing machine M is stopped via the shutter control panel 50, which stops the shutter curtain 1 that is being electrically raised or lowered. The shutter device according to this embodiment is equipped with a photoelectric sensor 9, and when a light beam extending horizontally between the guide rails 2 on both sides of the opening is interrupted, the opening / closing machine M is stopped via the shutter control panel 50, which stops the shutter curtain 1 that is being electrically raised or lowered.

[0014] In the shutter according to this embodiment, power is normally supplied to the opening / closing mechanism M from a commercial power source, but in the event of a power outage or the like, the shutter can be electrically opened and closed using an external power source. The shutter according to this embodiment is equipped with a power source switching device 6 that switches between the commercial power source and the external power source, and in the event of a power outage or the like, the external power source can be selected by the power source switching device 6, allowing the shutter to be electrically opened and closed using the external power source.

[0015] In this specification, an external power source refers to a power source supplied from outside, separate from the commercial power source supplied within a building, and is a so-called temporary power source. As the external power source, a general portable power source 7 that supplies AC 100V (pure sine wave) like a commercial power source or an in-vehicle outlet (a battery of a mobile vehicle) can be used. The shutter device according to this embodiment is primarily a shutter for a home (for example, a garage) or a store, and it is desirable to be able to use a power source that is easily available as the external power source.

[0016] 1, 11, 12, and 14 show a portable power supply (battery) 7 as an example of an external power supply, and power is supplied from the external power supply by connecting an attachment plug (A type) 80, which is an example of a connector at the end of an external power supply cord 8, to an outlet (A type) 70, which is an example of a connector for the portable power supply 7. In FIGS. 4 and 13, power is supplied from the external power supply by connecting an attachment plug (A type) 80 at the end of an external power supply cord 8 to an outlet (A type) 70' at the end of a cord 7' that is connected to an on-board outlet (not shown) that draws power from the car battery.

[0017] The power source switching device 6 is electrically connected to a first cord C1 as a power supply line from a commercial power source, an external power supply cord 8 as a power supply line from an external power source, and a second cord C2 as a power supply line to the opening / closing device M. By electrically connecting the first cord C1 and the second cord C2 in the power source switching device 6, power from the commercial power source is supplied to the opening / closing device M via the first cord C1 and the second cord C2 as a power supply path, and by electrically connecting the external power supply cord 8 and the second cord C2, power from the commercial power source is supplied to the opening / closing device M via the external power supply cord 8 and the second cord C2 as a power supply path, and the shutter curtain 1 is electrically raised and lowered by opening and closing operations from the electric opening / closing operation unit 5.

[0018] As shown in Figures 1 and 2, a first end of the first cord C1 is connected to a commercial power supply (100V AC) via a circuit breaker Br, and a second end is connected to a power supply switching device 6. The first cord C1 according to this embodiment is a two-core VCTF cable. The first cord C1 typically extends inside a pipe buried in the building frame or inside a wiring cover installed on a wall surface.

[0019] A first end of the external power supply cord 8 is provided with an attachment plug 80 connectable to an external power source (AC 100V), and a second end is connected to the power supply switching device 6. The external power supply cord 8, whose second end is fixed to the power supply switching device 6, extends outside the body when connected to an external power source. The external power supply cord 8 according to this embodiment is a curled cord. In the curled cord constituting the external power supply cord 8 according to this embodiment, the length of the curled cord when hanging down under its own weight is shorter than the distance between the height of the case 60 of the power supply switching device 6 attached to the body (to which the second end of the external power supply cord 8 is fixed) and the floor surface. When the external power supply cord 8 (curled cord) hangs down from the case 60, the lower end of the external power supply cord 8 (the attachment plug 80 at the first end) is spaced above the floor surface.

[0020] The curled cord is an example of the external power supply cord 8 and is not intended to limit the specific type of cord that can be used as the external power supply cord 8. However, using a curled cord as the external power supply cord 8 has the following advantages: The curled cord can be further extended from a state in which it hangs down from the power supply switching device 8 under its own weight, and when the second end is fixed to the power supply switching device 8 and the curled cord hangs down under its own weight, the first end (lower end) is spaced above the floor, preventing the attachment plug 80 at the first end from being grounded (if wet) when the second cord C2 hangs down, thereby preventing it from getting wet (which could cause a current leak when connected to an external power source).

[0021] A first end of the second cord C2 is connected to the switch M, and a second end is connected to the power supply switching device 6. The second cord C2 according to this embodiment is a two-core VCTF cable. The second cord C2 typically extends inside a pipe buried in the building frame or inside a wiring cover provided on the wall surface, and is not exposed to the outside. In the power supply switching device 6, the second end of the second cord C2 can be selectively connected to the second end of the first cord C1 and the second end of the external power supply cord 8.

[0022] Under normal circumstances, the second end of the first cord C1 and the second end of the second cord C2 are electrically connected in the power supply switching device 6, and the opening / closing device M is connected to a commercial power source via a power supply path consisting of the first cord C1 and the second cord C2, so that the shutter operates using power supplied from the commercial power source.

[0023] When the commercial power supply is disabled due to a power outage or the like, the power supply switching device 6 switches the connection destination of the second end of the second cord C2 to the second end of the external power supply cord 8, and the opening / closing device M is connected to the external power supply via a power supply path consisting of the external power supply cord 8 and the second cord C2, so that the shutter operates using power supplied from the external power supply.

[0024] The power supply switching device 6 is a power supply switching unit having a power supply switching section 61, and the power supply switching unit according to this embodiment is a power supply switching box having a case 60, the power supply switching section 61, a storage section 62 for storing the external power supply cord 8, and a lid 63. In one embodiment, the power supply switching device 6 is embedded in a wall so that the lid 63 is flush with the wall. Alternatively, the power supply switching device 6 may be attached externally to the wall. The power supply switching unit according to this embodiment has a case 60, and the power supply switching section 61 is housed in the case 60, but the power supply switching unit is not limited to one having a case, and the power supply switching section may not be housed in a case.

[0025] In this specification, the power supply switching device 6 or power supply switching unit refers to a power supply switching device in the narrow sense, and the power supply switching device in the broad sense includes the power supply switching device 6 as a power supply switching unit, the first cord C1, the second cord C2, and the external power supply cord 8.

[0026] 6 to 10, the case 60 includes an upper wall 600, a first side wall 601, a second side wall 602, a lower wall 603, a rear bottom wall 604, and a four-sided front edge 606 having a horizontally rectangular opening 605 formed therein. The opening 605 can be opened and closed by a lid 63. The second side wall 602 side of the lid 63 is the rotation base end side, and the first side wall 601 side is the rotation tip side. The rotation direction of the lid 63 is not limited to the illustrated embodiment. The second side wall 602 side may be the rotation tip side and the first side wall 601 side may be the rotation base end side, or either the upper wall 600 side or the lower wall 603 side may be the rotation tip side and the other side may be the rotation base end side. Insertion holes (not shown) for the first cord C1 and the third cord C3 are formed in the upper wall 600 of the case 60, and the piping (not shown) of the first cord C1 and the piping (not shown) of the third cord C3 are connected thereto.

[0027] Inside the case 60, the portion close to the first side wall 601 is a power supply switching unit 61, and a recessed storage unit 62 is formed adjacent to the power supply switching unit 61. The power supply switching unit 61 has a front surface 610, and a switching operation unit 611 and a light-emitting unit (external power indicator light) 612 are provided on the surface of the front surface 610. The front surface 610 and storage unit 62 of the power supply switching unit 61 are located in an opening 605 of the case 60, and when the lid 63 is in the closed position, the opening 605 is closed, and the front surface 610 of the power supply switching unit 61 and the storage unit 62 are concealed, and when the lid 63 is in the open position, the opening 605 is opened, and the front surface 610 of the power supply switching unit 61 and the storage unit 62 are exposed.

[0028] The second end of the first cord C2, the second end of the external power supply cord 8, and the second end of the second cord C2 are housed in a space provided behind the front part 610 of the power source switching unit 61, and this space forms a cord housing part 613. The power source switching unit 61 is provided with switching means 614 that selectively switches between a commercial power source and an external power source, and by operating the switching means 614 with the switching operation part 611, the electrical connection between the second end of the first cord C1 and the second end of the second cord C2, both of which are housed in the cord housing part 613, and the electrical connection between the second end of the external power supply cord 8 and the second end of the second cord C2 are selectively switched.

[0029] The storage section 62 has a first side surface 620 on the power switching section 61 side, a second side surface 621 on the rotation base end side (second side wall 602 side) of the lid body 63, an upper surface 622, a lower surface 623, and a bottom surface 624 on the rear side, and a second end side of the external power supply cord 8 is fixed to the first side surface 620, and the external power supply cord 8 is stored in the space surrounded by these surfaces. In this embodiment, the storage section 62 is formed by five flat surfaces (the first side surface 620, the second side surface 621, the upper surface 622, the lower surface 623, and the bottom surface 624), but the shape of the storage section 62 is not limited thereto, and for example, some or all of the surfaces of the storage section 62 may be curved.

[0030] 16 , when the external power supply cord 8 is stored in the storage section 62, a band 627 may be provided to span between an inner front surface 625 above the upper surface 622 of the storage section 62 and an inner front surface 626 below the lower surface 623. The band 627 is detachably attached to the inner front surface 625 and the inner front surface 626 by, for example, a hook-and-loop fastener. By pressing the external power supply cord 8 stored in the storage section 62 with the band 627, the stored position of the external power supply cord 8 can be maintained. Furthermore, a raised piece may be provided near the front end of the lower surface 623 of the storage section 62.

[0031] The cord storage section 62 and the cord storage section 613 are adjacent to each other via a first side surface 620. The top wall 600 of the case 60 and the top surface 622 of the storage section 62 are spaced apart, forming an upper space through which the cord extends. The cord storage section 613 of the power supply switching section 61 and the upper space are in communication. In this embodiment, an inner front surface 625 above the top surface 622 of the storage section 62 and an inner front surface 626 below the bottom surface 623 are flush with the front surface 610 of the power supply switching section 61. A second end of the external power supply cord 8 is fixed to the first side surface 620 of the storage section 62. The second end of the external power supply cord 8 is inserted through the first side surface 620 and positioned within the cord storage section 613 of the power supply switching section 61.

[0032] The second end (portion on the second end side) of the first cord C1 is located within the cord accommodating section 613 of the power source switching unit 61, the second end of the external power supply cord 8 is inserted through the first side surface 620 and is located within the cord accommodating section 613 of the power source switching unit 61, and the second end (portion on the second end side) of the second cord C2 is located within the cord accommodating section 613 of the power source switching unit 61, and by switching operation of the switching operation unit 611 of the power source switching unit 61, the switching means 614 is activated to selectively switch between the connection between the second end of the first cord C1 and the second end of the second cord C2, and the connection between the second end of the external power supply cord 8 and the second end of the second cord C2.

[0033] The power supply switching means 614 is configured to selectively assume a first state in which the second end of the first cord C1 is connected to the second end of the second cord C2 and the connection between the second end of the external power supply cord 8 and the second end of the second cord C2 is disconnected, and a second state in which the connection between the second end of the first cord C1 and the second end of the second cord C2 is disconnected and the second end of the external power supply cord 8 is connected to the second end of the second cord C2. The power supply switching means 614 can be switched between the first state and the second state by the switching operation of the switching operation unit 611.

[0034] The switching operation unit 611 protrudes from the front surface 610 and includes an upper first portion 6110 and a lower second portion 6111. When the first portion 6110 of the switching operation unit 611 is pressed in a first position, the power switching means 614 is in a first state, and the second end of the first cord C1 and the second end of the second cord C2 are connected to each other so that commercial power is supplied to the opening / closing device M.

[0035] In the second position where the second portion 6111 of the switching operation unit 611 is pressed, the power supply switching means 614 is in the second state, the second end of the external power supply cord 8 is connected to the second end of the second cord C2, and external power can be supplied to the opening / closing device M, and by connecting the first end of the external power supply cord 8 to the external power supply, external power can be supplied to the opening / closing device M. When the external power supply is enabled, the light-emitting unit 612 on the front surface 60 of the power supply switching unit 6 emits light. The light-emitting unit 612 is, for example, an LED display unit, and is configured to emit light using power from the external power supply.

[0036] When the lid 63 is in the closed position, the opening 605 on the front of the case 60 is closed, and the front portion 610 (switching operation portion 611, light-emitting portion 612) of the power supply switching portion 61, the storage portion 62, and the external power supply cord 8 stored in the storage portion 62 are located on the back of the lid 63. When the lid 63 is in the open position, the opening 605 on the front of the case 60 is open, and the front portion 610 (switching operation portion 611, light-emitting portion 612) of the power supply switching portion 61 is exposed, making it possible to operate the switching operation portion 611, making the light emitted by the light-emitting portion 612 visible, and opening the storage portion 62, making it possible to pull out the external power supply cord 8 stored in the storage portion 62.

[0037] The rotation base end side of the lid body 63 is rotatably connected to the case 6. An operating tool 630 for the lid body 63 is provided on the rotation tip side of the lid body 63, and the operating tool 630 has a rotatable first part (knob 6300) protruding from the surface of the rotation tip side of the lid body 63 and a rotatable second part 6301 protruding from the back surface of the rotation tip side of the lid body 63, and the second part 6301 is provided with a locking piece 631 that rotates by operating (rotating) the operating tool 630, and when the lid body 63 is in the closed position, the locking piece 631 is rotated by operating the operating tool 63 to lock onto a locked part (not shown) formed on an inner side surface 607 on the first side wall 601 side of an opening 605 on the front surface of the case 60, thereby locking the lid body 63 in the closed position.

[0038] The switching operation unit 611 of this embodiment is configured to take a first position (see Figure 9) in which the upper first part 6110 is pressed and the lower second part 6111 protrudes, a second position (see Figure 7) in which the lower second part 6111 is pressed and the upper second part 6110 protrudes, and a third position (power OFF state, see Figure 8) between the first and second positions.

[0039] Under normal circumstances, the switching operation unit 611 is in the first position, and power from the commercial power source is supplied to the opening / closing device M. When it is necessary to electrically open or close the shutter during a power outage or the like, the external power source (portable power source 7) is started, the cover 63 of the power source switching device 6 is opened, and the second portion 6111 on the lower side of the switching operation unit 611 is pressed to change the switching operation unit 611 from the first position to the second position (see FIG. 11). When the external power supply cord 8 is pulled out of the storage section 62 and the attachment plug 80 at the first end of the external power supply cord 8 is inserted into the outlet 70 of the portable power source 7 serving as the external power source, the light-emitting unit 612 emits light, and it can be confirmed that the external power source is active (see FIG. 12).

[0040] The shutter can be electrically opened and closed using an external power source by operating the electric opening / closing operation unit 5 or the remote control unit 5' (see Figure 13). In Figure 13, power is supplied from the external power source by connecting an attachment plug 80 at the end of an external power supply cord 8 to an outlet 70' at the end of a cord 7' that is connected to an on-board outlet (not shown).

[0041] After the shutter is electrically driven using an external power source, the upper first part 6110 of the switching operation unit 611 is pressed to change the switching operation unit 611 from the second position to the first position, the connection between the first end of the external power supply cord 8 and the external power source is disconnected, and the lid portion 63 is closed with the external power supply cord 8 stored in the storage portion 62.

[0042] According to this embodiment, a protrusion 632 is provided on the back surface of the pivot tip side of the cover 63 so as to be located in front of the upper first portion 6110 of the switching operation unit 611 when the cover 63 is in the closed position. When the cover 63 is in the closed position, the tip of the protrusion 632 is in light contact with or close to the first portion 6110 of the switching operation unit 611 in the first position. In other words, when the cover 63 is closed while the switching operation unit 611 is in the second position, the protrusion 632 on the back surface of the cover 63 comes into contact with the first portion 6110 in the protruding position and pushes in the first portion 6110, so that when the cover 63 is in the closed position, the switching operation unit 611 is in the first position.

[0043] In this embodiment, the tip side portion of the second portion 6301 of the operating tool 630 forms a protrusion 632. In the cover 63 of this embodiment, when the cover 63 is in the closed position or approaching the closed position, the second portion 6301 of the operating tool 630 is positioned in front of the upper first portion 6110 of the switching operation unit 611 of the power switching unit 61. That is, when the cover 63 is in the closed position, the protrusion 632 provided on the back surface at the tip of the rotation is positioned in front of the upper first portion 6110 of the switching operation unit 611. Note that the protrusion 632 may be separate from the operating tool 630. For example, the positions of the second portion 6301 of the operating tool 630 and the upper first portion 6110 of the switching operation unit 611 may not correspond to each other, and the protrusion 632 provided separately from the operating tool 630 may abut against the upper first portion 6110 of the switching operation unit 611 when the cover 63 is in the closed position.

[0044] As shown in Figures 7 to 9, when the switching operation unit 611 is in the second position, the protrusion dimension of the protrusion 632 is such that when the lid body 63, which is in the open position, approaches the closed position, it comes into contact with the first part 6110 (protruding position) on the upper side of the switching operation unit 611, and as the lid body 63 further rotates slightly in the closing direction from this state, the first part 6110, which is in the protruding position, is slightly pushed in, bringing the switching operation unit 611 into the third position (power OFF state), and when the lid body 63 further rotates slightly in the closing direction from this state to reach the closed position, the first part 6110 is further pushed in, bringing the switching operation unit 611 into the first position.

[0045] In this embodiment, a protrusion 632 is provided on the back side of the lid portion 63, located on the upper first part 6110 of the switching operation unit 611 of the power supply switching unit 61, when the lid portion 63 approaches the closed position.Even if, after using an external power source, you forget to switch the switching operation unit 611 to the first position, when the lid portion 63 reaches the closed position, the protrusion 632 on the back side of the lid portion 63 pushes in the upper first part 6110 of the switching operation unit 611, and at the same time that the lid portion 63 reaches the closed position, the switching operation unit 611 reaches the first position.

[0046] In the switching operation unit 611 according to this embodiment, when the first part 6110 of the switching operation unit 611 is pressed in a first position, the power supply switching means 614 is in a first state, and the second end of the first cord C1 and the second end of the second cord C2 are connected so that commercial power is supplied to the opening / closing device M; when the second part 6111 of the switching operation unit 611 is pressed in a second position, the power supply switching means 614 is in a second state, and the second end of the external power supply cord 8 is connected to the second end of the second cord C2 so that external power can be supplied to the opening / closing device M; however, the power supply switching function may be reversed; specifically, when the first part 6110 of the switching operation unit 611 is pressed in the first position, the power supply switching means 614 is in a second state and is connected to the external power supply; and when the second part 6111 of the switching operation unit 611 is pressed in the second position, the power supply switching means 614 is in a first state and is connected to the commercial power supply. Furthermore, the first portion 6110 and the second portion 6111 of the switching operation unit 611 may be positioned in the left-right direction. It should be noted that the position of the protrusion 632 provided on the back surface of the lid body 63 may also vary depending on the specific configuration of the switching operation unit 611.
