  By the way, it is preferable that the power cord extending from the switch is wired so as not to be exposed to rainwater or dust as much as possible up to a predetermined location (for example, an outlet of a commercial power supply). In some cases, wiring is required in a gap formed between the bracket for use and the shutter case.

  However, the distance between the support bracket and the shutter case is narrow, and the work is performed to support the switch (in the above example, the switch and the winding shaft that houses the switch) on the support bracket. Sometimes, at the same time as this work, the power cord is inserted into the hole formed in the support bracket and the power cord is directly wired to the gap formed between the support bracket and the shutter case. It is not easy to do.

  In addition, since the power cord is wired in this way, the power cord is bent in the vertical direction from the hole of the support bracket to the gap, so that the power cord is being routed to the gap. In the case where the power cord extending from the switch is entangled between the switch and the support bracket after the power cord is wired in the gap portion, it is not easy to unwind this entanglement.

  For this reason, the wiring method and wiring device which make wiring work of the power cord extended from the switch easy are demanded.

  An object of the present invention is to provide a wiring method and a wiring structure for an electric switchgear that can facilitate the wiring work of a string-like member extending from the switch.

  The wiring method of the electric switch according to the present invention includes an opening / closing device for moving at least an opening / closing movement of the opening / closing body, a support member for supporting the opening / closing device, and the opening / closing device. In a wiring method for an electric switchgear comprising a string member that extends, and a storage member for storing the switch and the support member, at least when the switch is supported by the support member An operation step of inserting the string-like member through a first hole formed in the support member and a second hole formed in the storage member to temporarily protrude outside the storage member; and the storage member A step of inserting the string-like member once protruded to the outside into a third hole formed in the storage member and passing through a gap formed between the support member and the storage member; Characterized by including, Is shall.

  As described above, the distance between the support member and the storage member is narrow, and at least when the opening / closing machine is supported by the support member, the string-like member is inserted into the hole formed in the support member. It is not easy to insert the string-like member directly into the gap portion formed between the support member and the storage member while being inserted.

  Further, as described above, by wiring the string-like member in this way, the string-like member is bent and wired, for example, in the vertical direction from the hole of the support member to the gap portion. In the middle of wiring the string-like member to the gap, or after wiring the string-like member to the gap, the string-like member extending from the opening / closing machine is between the opening / closing machine and the support member. When it is entangled in, it is not easy to unwind this entanglement.

  On the other hand, in the present invention, at least the opening / closing machine is supported by the support member (as described later, when the opening / closing machine is housed in the winding shaft, the winding shaft is When the support member is supported), the string-like member is inserted into the first hole formed in the support member and the second hole formed in the storage member so as to be outside the storage member. A work process for once projecting is performed.

  Then, after the opening / closing machine is supported by the support member, the string-like member once protruded to the outside of the storage member is inserted into the third hole formed in the storage member to support the support. An operation step of passing through the gap formed between the member and the storage member is performed.

  Thus, after the operator supports the opening / closing device on the support member, the string member once protruded to the outside of the storage member is inserted into the third hole formed in the storage member. It becomes possible to concentrate on performing the operation of passing through the gap formed between the support member and the storage member.

  In addition, since a part of the cord-like member is exposed to the outside of the storage member, the cord-like member is wired to the gap portion after the switch is supported by the support member. When the string-like member extending from the opening / closing machine is entangled between the opening / closing machine and the support member after the string-like member is wired to the gap portion, the operator Can easily perform the work of untangling the string-like member by pulling the portion of the string-like member exposed to the outside of the storage member.

  For this reason, according to the present invention, when at least the switch is supported by the support member, the string-like member is inserted into a hole formed in the support member and the string-like member is directly supported by the support member. Compared with the case where wiring is performed in the gap formed between the member and the storage member, wiring work is facilitated.

  Thus, according to the wiring method of the electric switchgear according to the present invention, the wiring work of the string-like member extending from the switch can be facilitated.

  In this invention, although the formation location of the said 2nd hole in the said storage member may be arbitrary locations, it is preferable to form in the location facing the formation location of the said 1st hole in the said storage member.

  According to this, compared with the case where the formation location of the second hole is a location that does not face the formation location of the first hole, the string-like member inserted through the first hole is further inserted into the second hole. Work becomes easier.

  Furthermore, it is preferable that the center position of the first hole coincides or substantially coincides with the center position of the second hole.

  According to this, as compared with the case where the center position of the first hole does not match or substantially does not match the center position of the second hole, the string-like member inserted through the first hole is further replaced with the second hole. The work of inserting into is easier.

  Further, in the present invention, the formation position of the third hole in the storage member may be an arbitrary position. For example, the third hole is separated from the formation position of the second hole in the opening / closing movement direction of the opening / closing body. It may be formed at a location where the second hole is formed, or may be formed at a location that is separated from the formation location of the second hole in the opening / closing movement direction of the opening / closing body.

  Therefore, for example, when extending the string-like member inserted through the first hole and the second hole in the closing movement direction of the opening / closing body, the third hole extends from the formation position of the second hole. It is formed at a location spaced apart in the closing movement direction of the opening / closing body, or a location spaced apart from the formation location of the second hole in the closing movement direction of the opening / closing body.

  In the present invention, it is preferable that the diameter dimension of the second hole is the same as or larger than the diameter dimension of the first hole.

  According to this, compared with the case where the diameter dimension of the said 2nd hole is smaller than the diameter dimension of the said 1st hole, the operation | work which penetrates the said string-like member penetrated to the said 1st hole to the said 2nd hole is easy. It becomes.

  In the present invention, as long as the string-like member is a string-like member, the shape, structure, use, etc. may be arbitrary, and the first example of the string-like member is connected to the switch. An electric cord (for example, an electric motor that constitutes the switch, a control device that controls the driving of the electric motor, a power cord (power line) for supplying power to a brake that brakes the electric motor, or the like) Line). A second example of the string-like member is a switching member (wire member) for switching on and off the brake of the switch when the electric motor of the switch is stopped. is there. Furthermore, a third example of the string-like member is a signal line for transmitting (transmitting) a control signal from an operation device for operating rotation and stop of the electric motor of the switch to the control device ( Signal cable). Still further, a fourth example of the string-like member includes an obstacle sensing means for sensing (detecting) an obstacle present in the closing movement direction of the opening / closing body during the closing movement of the opening / closing body. , A signal line (signal cable) for transmitting (transmitting) an obstacle detection signal from the obstacle detection means to the control device that controls driving of the electric motor.

  In the present invention, the number of the string-like members may be one, or at least two (in other words, a plurality). In the former case, the string-like member may be, for example, any one of the above-described examples of the string-like member. In the latter case, the string-like member may be one type (for example, the string described above). It may be configured by a string-like member of any of the examples of the string-shaped member, or may be configured by a plurality of types of string-shaped members (for example, at least two examples of the above-described examples of the string-shaped member). May be used.

  As an example of the latter case, there are at least two of the string-like members, one of these string-like members is an electric cord connected to the switch, and the other is the switch The switching member for switching on and off the brake of the switch when the electric motor is stopped can be mentioned.

  In the present invention, an operation step of inserting a guide member into at least one of the first hole, the second hole, and the third hole is performed, and then the string-like shape is formed in the inner hole of the guide member. An operation process for inserting the member may be performed.

  According to this, when the said string-like member passes each said hole, it can prevent with a guide member that this string-like member is rubbed and damaged with each said hole. That is, it is possible to prevent a decrease in durability of the string-like member due to rubbing against the holes.

  The guide member that fits into the first hole is preferably formed of a softer material than the support member, and the guide member that fits into the second hole and the third hole includes the storage member. It is preferable to form with a softer material than a member.

  In the present invention, a part of the guide member having a curved portion curved in accordance with the wiring direction of the string-like member is fitted into at least one of the second hole and the third hole. A work process of holding the guide member to the storage member with a stopper may be performed, and thereafter, a work process of inserting the string-like member through the inner hole of the guide member may be performed.

  According to this, as described above, the guide member can not only prevent the string-like member from being rubbed and damaged by the holes when the string-like member passes through the holes. The string-like member can be bent and wired in a predetermined direction by the bending guide action of the bending portion of the guide member.

  In the above-described present invention, the opening / closing body may be a shutter curtain that is drawn out and taken up from a take-up shaft, and is not drawn out and taken up from the take-up shaft. Sliding door).

  Moreover, the said opening / closing machine may be accommodated in the inside of the said winding shaft, and may be arrange | positioned outside the said winding shaft.

  In the former case, the winding shaft is supported by the support member together with the switch. On the other hand, in the latter case, each of the opening / closing machine and the winding shaft may be supported by the support member, the opening / closing machine is supported by the supporting member, and the winding shaft is supported by the supporting member. It may be supported by another support member.

  In the former case, it is preferable that the string-like member extending from the opening / closing machine extends from the axial end of the winding shaft.

  In addition, in this invention, when another member, such as an accessory, is attached to the termination | terminus part of a string-like member, a middle part, etc., the radial dimension of the 1st-3rd hole is a string containing the said another member. It is good also as what is larger than the diameter dimension of a shaped member, and does not need to do it. In other words, the first to third holes may or may not have a diameter that allows the string-like member to be inserted when another member is attached.

  In the latter case, after the work process of inserting the string-like member through the first to third holes is performed, the work process of attaching the separate member to the string-like member is performed.

  Here, the first example of the separate member is a case where the string-like member is the electric cord, and the electric cord is attached to the terminal portion of the power cord when the cord is a power cord (power line). It is a power plug.

  A second example of the separate member is a ferrite for attenuating external noise from the signal line when the string-like member is the electric cord and the electric cord is a signal line. Is the core.

  Further, in the third example of the separate member, when the string-like member is a switching member (wire member), an operation member (switching member) is attached to the terminal portion of the switching member and operates the switching member. In the case of pulling the member, the pulling operation member).

  The wiring structure of the electric switchgear according to the present invention includes an opening / closing device for opening and closing the opening / closing body, and a support member for supporting the opening / closing device, and the opening / closing device. In the wiring structure of the electric switchgear that includes a string member that extends, and a storage member that stores the switch and the support member, the string member is formed on the support member. The first hole and the second hole formed in the storage member are inserted to protrude outside the storage member, and the third hole formed in the storage member is inserted into the support member and the second hole. It passes through a gap formed between the storage member and the storage member.

  As described above, the distance between the support member and the storage member is narrow, the string-like member is inserted through a hole formed in the support member, and directly the support member and the storage member. In the case of a wiring structure that passes through the gap formed between the members, the string-like member is bent from the hole of the support member to the gap, for example, in a vertical direction and wired. Therefore, the string-like member extending from the opening / closing machine is connected to the opening / closing machine while the string-like member is wired to the gap part or after the string-like member is wired to the gap part. When entangled with the support member, it is not easy to unwind the entanglement.

  On the other hand, in the present invention, the string-like member is inserted into the first hole formed in the support member and the second hole formed in the storage member and protrudes to the outside of the storage member. In addition, the wiring structure is inserted through a third hole formed in the storage member and passes through a gap formed between the support member and the storage member.

  A power line (which may or may not include a ground wire) 39, which is a power cord that is a string-like member in the present embodiment, is connected to each of the above-described devices constituting the switch 21. In order to supply power to these devices. As shown in FIG. 4, the power line 39 extending from the switch 21 extends from an end 20 </ b> B on the support bracket 8 side, which is one end of the electric winding shaft 20.

  As will be described later, the brake 21D of the opening / closing machine 21 indicates that the winding shaft 20 is rotated by the rotational driving force of the electric motor 21C and the shutter curtain 31 reaches the fully open position or the fully closed position. When the detection signal is input to the control device 21B via a signal line (not shown) that is a string-like member, or the rotation or stop of the electric motor 21C is operated. When the stop signal from the operation device for input is input to the control device 21B via the signal line, the rotation drive of the output member of the electric motor 21C is stopped and the winding shaft 20 is stopped. belongs to.

  The opening / closing machine 21 is provided with a ring-shaped drive member 22 that is rotated by rotation of the output member of the electric motor 21 </ b> C, and a winding shaft 20 is formed in a plurality of grooves 22 </ b> A formed in the circumferential direction of the drive member 22. Since the protrusion 20 </ b> A provided on the inner surface is inserted, the drive member 22 and the winding shaft 20 are connected in the rotational direction of the winding shaft 20. For this reason, when the drive member 22 is rotated by the rotational drive of the output member of the electric motor 21C, the winding shaft 20 is rotated. Further, a ring-shaped driven member 23 that rotates integrally with the winding shaft 20 is fitted to the outer periphery of the opening / closing device 21, and the rotation of the winding shaft 20 by the rotational driving force of the electric motor 21 </ b> C is the driven. The member 23 serves as a rotary bearing member between the winding shaft 20 and the switch 21.

  On the other hand, a return spring unit 24 is inserted into the end of the electric winding shaft 20 on the support bracket 7 side. The return spring unit 24 is disposed between the non-rotating central shaft 25, two wheel members 27 rotatably disposed on the central shaft 25 by bearing members 26, and the wheel members 27. And two return springs 28 by a torsion coil spring. Each wheel member 27 is coupled to the take-up shaft 20 by rivets or the like, and one end of each return spring 28 is coupled to the central shaft 25 by a coupling tool 29A, and the other end is coupled to the winding shaft 29 by a coupling tool 29B. The wheel member 27 is connected.

  For this reason, after the upper end of the electric shutter curtain, which will be described later, is connected to the electric winding shaft 20, the electric winding shaft 20 winding the electric shutter curtain is driven by the rotational driving force of the electric motor 21C. When the electric shutter curtain is drawn out by rotating around the non-rotating central shaft 25, a return spring force is accumulated in the return spring 28, and this return spring force is applied to the electric winding shaft 20 by the electric motor 21C. This is used as an auxiliary force when the electric shutter curtain is wound up in reverse rotation by the rotational driving force.

  In the present embodiment, as shown in FIG. 4, the shaft end portion 25 </ b> A of the central shaft 25 protrudes from the winding shaft 20, and therefore, this shaft end portion 25 </ b> A is in the electric winding shaft 20. An end portion on the side of the support bracket 7 is formed, and the shaft end portion 25A is supported by the bearing portion 9 of the support bracket 7 which is also used for the manual winding shaft 6. ing. The shaft end portion 25A and the bearing portion 9 are connected by a bolt 14 and a nut 15 with the same structure as described in FIGS. 3 and 4 as shown in FIGS. Yes.

  For this reason, in this embodiment, in order to support the shaft end portion 25A of the central shaft 25 forming the end portion on the support bracket 7 side of the electric winding shaft 20, the manual shutter device for windows is used. The existing support bracket 7 and the existing bearing 9 provided on the bracket body 7A of the support bracket 7 are used.

  The bracket body 7A and the shaft end portion 25A of the center shaft 25 are connected between the bracket body 7A of the existing support bracket 7 and the shaft end portion 25A of the center shaft 25 without being obstructed by the existing bearing portion 9. An intermediate construct may be intervened.

  7 shows a structure for connecting and supporting the end portion 20B of the electric take-up shaft 20 on the side of the support bracket 8 to the support bracket 8 described in FIG. 2 and FIG. 7 is a front view of this structure, and FIG. 8 is a plan view of this structure. An end 20B of the electric take-up shaft 20 on the side of the support bracket 8 is connected and supported to the bracket body 8A of the support bracket 8 by an intermediate structure 30 whose specific structure will be described later. More specifically, an end 21A on the support bracket 8 side of the switch 21 housed and fixed inside the electric winding shaft 20 is exposed from the winding shaft 20, and the electric motor 21C is exposed. This end portion 21A of the opening / closing device 21 which is a constituent element is connected and supported to the bracket body 8A of the support bracket 8 by the intermediate structural body 30, whereby the support bracket 8 of the electric winding shaft 20 is supported. The side end portion 20 </ b> B and the bracket body 8 </ b> A of the support bracket 8 are connected and supported via the switch 21 and the intermediate structure 30.

  Therefore, the existing support bracket 8 is used as it is even after the manual take-up shaft 6 is modified to the electric take-up shaft 20, and the support bracket 8 is also provided. The bearing 10 shown in FIGS. 2 and 3 is left as it is. The intermediate structure 30 for connecting the opening / closing machine 21 and the bracket main body 8A of the supporting bracket 8 is not obstructed by the bearing portion 10 and can be understood from the description below. The bracket body 8A is interposed.

  FIG. 9 shows a front view of the windowed electric shutter device after the manual winding shaft 6 has been modified to the electric winding shaft 20, and in this embodiment, the manual winding shaft 6 is shown. 1 to the electric winding shaft 20, the manual shutter curtain 3 shown in FIG. 1 is changed to the electric shutter curtain 31 shown in FIG. The left and right ends of the electric shutter curtain 31 whose upper end is connected to the electric take-up shaft 20 are slidably inserted into the pair of left and right guide rails 4 shown in FIG. By winding and unwinding by the electric winding shaft 20, the guide rail 4 guides and opens and closes up and down. The entirety of the shutter curtain 31 is formed by connecting a large number of slats 32 in the vertical direction, excluding ancillary members such as a seat plate.

  FIG. 10 is a cross-sectional view taken along line S10-S10 of FIG. 9. As shown in FIG. 10, curled portions 33 are formed at the upper and lower ends of each slat 32, and the lower end curl of the upper slat 32A is formed. The portion 33A and the upper end curl portion 33B of the lower slat 32B engage with each other so that the slats 32A and 32B are rotatably connected. Since each curled portion 33 has the same cross-sectional shape in the left-right direction, the curled portion 33 is located away from the pair of left and right guide rails 4, that is, inside the shutter case 5 shown in FIG. In this place, each slat 32 is in a state where it may slide in the left-right direction.

  In addition, when at least a part of the manual shutter curtain 3 shown in FIG. 1 is formed by connecting a plurality of slats, the intermediate structure 30 according to the present embodiment includes the manual winding shaft 6. The present invention can also be applied to the case where the manual shutter curtain 3 is used as the electric shutter curtain after being modified to the electric take-up shaft 20.

  That is, the intermediate structure 30 according to the present embodiment can also be applied to the case where the existing manual shutter curtain 3 at least partially formed by connecting slats is used as an electric shutter curtain.

  As shown in FIG. 4, a string-like member 35 made of a wire or the like extends from the opening / closing machine 21, and this string-like member 35 is one end of the central shaft 25 that is a hollow member. To the center shaft 25.

  The string-like member 35 is used to switch the above-described brake 21D, which is a component of the opening / closing device 21 together with the electric motor 21C, when the rotation of the electric winding shaft 20 is stopped. It is the switching member 35 for doing this. That is, when the electric shutter curtain 31 whose rotation of the electric winding shaft 20 is stopped because the brake 21D is on is fully opened or fully closed, for example, when a power failure occurs, the switching is performed. When the member 35 is pulled once, the brake 21D is turned off. Therefore, even if the winding shaft is modified from the manual winding shaft 6 to the electric winding shaft 20, the electric winding shaft 20 is restored. Is in a freely rotatable state, and therefore, the electric shutter curtain 31 can be manually opened and closed. When the switching member 35 is pulled once more, the brake 21D is turned on, so the switch 21 returns to the state before the pulling operation described above, and the electric winding shaft 20 is in a state where it cannot rotate freely. Thus, the electric shutter curtain 31 cannot be manually opened and closed.

  A mechanism for enabling the brake of the switch to be turned on and off by pulling the string-like member is already well known. For example, Japanese Patent Application Laid-Open No. 2004-27841 discloses a mechanism in which a clutch mechanism for transmitting a driving force of a motor to a winding shaft is disconnected and connected by pulling a string member. The embodiment is also provided with a mechanism similar to this. For this reason, the detailed description about the mechanism for enabling the brake 21D of the switch 21 to be turned on and off by pulling the switching member 35, which is the string-like member described above, is omitted.

  As can be seen from FIGS. 5 and 6, the bearing portion 9, like the bearing portion 10, projects in the outer diameter direction of the take-up shaft 20 from the bearing portion body 18 and the bracket body 7 </ b> A side of the bearing portion body 18. The flange portion 19 is formed. The bearing portion main body 18 has a bottom portion 18A and upright portions 18B and 18C rising from both ends of the bottom portion 18A, and thus has a U-shape that opens upward. Further, the flange portion 19 extends horizontally from the lower portion of the bearing portion main body 18, in other words, from the first protruding portion 19A that protrudes downward from the bottom portion 18A, and from both sides of the bearing portion main body 18, in other words, from the upright portions 18B and 18C. Or it consists of two 2nd protrusion parts 19B and 19C which protrude in a substantially horizontal direction, and these 1st and 2nd protrusion parts 19A-19C are couple | bonded with the bracket main body 7A with coupling tools, such as welding or a rivet. Thus, the bearing portion 9 formed by the bearing member is provided on the support bracket 7.

  13 is a partially enlarged view of the left support bracket 8 and the lid member 5C of the shutter case 5 shown in FIG. As shown in FIG. 13, the bracket body 8A of the support bracket 8 is formed with a circular or substantially circular hole 34 through which the power line 39 is inserted, and the left side surface portion of the shutter case 5 is formed on the left side surface portion. A hole 5G having the same or substantially the same diameter as the hole 34 is formed at a position facing the hole 34 in the cover member 5C. The center position of the hole 5G coincides with or substantially coincides with the center position of the hole 34, and the diameter dimension of the hole 5G is the same as or substantially the same as the diameter dimension of the hole 34. Further, as shown in FIG. 17 which is a perspective view schematically showing the lid member 5C shown in FIG. 4 (the display of the support bracket 8 and the like is omitted), the shutter curtain is opened from the hole 5G in the lid member 5C. Circular or substantially circular holes 5 </ b> H are formed at positions spaced downward in the closing movement direction of 31. The diameter dimension of the hole 5H may be smaller than the diameter dimension of the hole 5G as shown in FIG. 13, and may be the same as or substantially the same as the diameter dimension of the hole 5G.

  As shown in FIG. 13, the power line 39 is inserted into the hole 34 of the bracket body 8A and the hole 5G of the lid member 5C and protrudes outside the lid member 5C, and then the hole of the lid member 5B. It is inserted through 5H. Then, as shown in FIG. 13, the power supply line 39 inserted through the hole 5H passes through a gap S2 formed between the bracket body 8A and the lid member 5C, and then is shown in FIGS. In this way, the cover member 5C is exposed (projected) from the opening 5J that is long in the front-rear direction, which is the thickness direction of the shutter curtain 31 formed on the lower surface (bottom surface) 5K. The wiring state of the power line 39 thereafter is such that the terminal end of the power line 39 is connected to a power outlet disposed outdoors or indoors.

  For this reason, in this embodiment, the hole 34 formed in the bracket body 8A of the support bracket 8 is the first hole, and the hole 5G formed in the lid member 5C of the shutter case 5 is the second hole. The hole 5H formed in the lid member 5C of the shutter case 5 is a third hole.

  Thus, in the present embodiment, the power line 39 is inserted into the hole 34 of the bracket body 8A and the hole 5G of the lid member 5C and protrudes outside the lid member 5C, and into the hole 5H of the lid member 5B. The wiring structure is inserted and passes through a gap S2 formed between the bracket body 8A and the lid member 5C.

  11 and 12 are sectional views taken along lines S11-S11 and S12-S12 in FIG. The hole 34 formed in the bracket main body 8A of the support bracket 8 for passing the power supply line 39 shown in FIG. 11 is connected to the power supply line 39 in the bracket main body 8A as shown in FIG. The power supply line 39 is wired without interfering with the bearing portion 10, that is, without being disturbed by the bearing portion 10, because the portion is not obstructed by the bearing portion 10.

  As can be seen from FIGS. 5 and 6, the portion of the electric take-up shaft 20 of the bracket main body 7 </ b> A of the support bracket 7 that is surrounded by the bottom 18 </ b> A of the bearing body 18 and the upright portions 18 </ b> B and 18 </ b> C. A circular or substantially circular hole 36 is formed at a location that coincides with or substantially coincides with the extension axis.

  The support bracket 7 is disposed on the opposite side of the electric winding shaft 20 in the axial direction from the support bracket 8 with or without the intermediate structure 30 described above. The portion where the hole 36 is formed in the support bracket 7 is a portion that is not obstructed by the bearing portion 9 provided in the bracket body 7A of the support bracket 7. Since the switching member 35 inserted through the center shaft 25 and projecting from the other end of the center shaft 25 is passed through the hole 36, the switching member 35 does not interfere with the bearing portion 9, In other words, it is wired without being disturbed by the bearing 9.

  14 is a partially enlarged view of the right support bracket 7 and the lid member 5B of the shutter case 5 shown in FIG. As shown in FIG. 14, a hole 5E having the same or substantially the same diameter as the hole 36 is formed at a position facing the hole 36 of the bracket body 7A in the lid member 5B constituting the right side surface portion of the shutter case 5. Has been. The center position of the hole 5E coincides with or substantially coincides with the center position of the hole 36, and the diameter dimension of the hole 5E is the same as or substantially the same as the diameter dimension of the hole 36. Further, as shown in FIG. 19, which is a simplified perspective view of the lid member 5B shown in FIG. 4 (the display of the support bracket 7 etc. is omitted), the shutter curtain is opened from the hole 5E in the lid member 5B. A hole 5 </ b> F is formed at a position spaced apart in a downward movement direction of 31. Note that the diameter dimension of the hole 5F may be smaller than the diameter dimension of the hole 5E as shown in FIG. 14, or may be the same as or substantially the same as the diameter dimension of the hole 5E.

  As described above, the switching member 35 is inserted into the hole 36 of the bracket body 7A and the hole 5E of the lid member 5B and protrudes to the outside of the lid member 5B, and then inserted into the hole 5H of the lid member 5B. . Then, as shown in FIG. 14, the switching member 35 inserted through the hole 5F passes through a gap S1 formed between the bracket body 7A and the lid member 5B, and then is shown in FIGS. In this way, the cover member 5B is exposed (projected) from the opening 5I that is long in the front-rear direction, which is the thickness direction of the shutter curtain 31 formed on the lower surface (bottom surface) 5L. In the subsequent wiring state of the switching member 35, the terminal portion of the switching member 35 is connected to the tension operation member 38 disposed on one of the pair of left and right guide rails 4. For this reason, when the pulling operation member 38 is pulled, the brake 21 </ b> D of the switch 21 is switched on and off via the switching member 35.

  For this reason, in this embodiment, the hole 36 formed in the bracket body 7A of the support bracket 7 is the first hole, and the hole 5E formed in the lid member 5B of the shutter case 5 is the second hole. The hole 5F formed in the lid member 5B of the shutter case 5 is a third hole.

  Thus, in the present embodiment, the power line 39 is inserted into the hole 34 of the bracket body 8A and the hole 5G of the lid member 5C and protrudes outside the lid member 5C, and into the hole 5H of the lid member 5B. The wiring structure is inserted and passes through a gap S2 formed between the bracket body 8A and the lid member 5C.

  In the present embodiment, the wiring work of the power supply line 39 extending from the switch 21 is performed at the time of supporting both end parts of the winding shaft 20 in the axial direction on the bearing parts 9 and 10. After the end portion is inserted into the hole 34 of the bracket body 8A and the hole 5G of the lid member 5C, it is not immediately (directly) inserted into the hole 5H of the lid member 5C. As shown in FIG. 2, the power supply line 39 is inserted into the hole 34 of the bracket body 8 </ b> A and the hole 5 </ b> G of the lid member 5 </ b> C and once outside the lid member 5 </ b> C of the shutter case 5. It is intended to protrude (expose). In consideration of the subsequent wiring work, it is preferable that the amount of protrusion of the power supply line 39 that is once protruded outside the lid member 5C is as large as possible. That is, it is preferable that the power supply line 39 is protruded only to protrude outside the lid member 5C.

  Further, the wiring work of the switching member 35 extending from the opening / closing machine 21 is also performed during the work of supporting both end portions in the axial direction of the winding shaft 20 on the bearing portions 9 and 10, similarly to the power supply line 39. At this time, after the terminal portion of the switching member 35 is inserted into the hole 36 of the bracket body 7A and the hole 5E of the lid member 5B, it is not immediately (directly) inserted into the hole 5F of the lid member 5B. 15 and FIG. 18 (the support bracket 7 and the like are not shown), the switching member 35 is inserted into the hole 36 of the bracket main body 7A and the hole 5E of the lid member 5B to cover the shutter case 5. It protrudes (exposes) once outside the member 5B. As in the case of the power supply line 39 described above, in consideration of the subsequent wiring work, it is preferable that the amount of protrusion of the switching member 35 that temporarily protrudes outside the lid member 5B is as large as possible. That is, it is preferable that the switching member 35 protrudes only to protrude outside the lid member 5B.

  The work of supporting both ends of the winding shaft 20 in the axial direction on the bearings 9 and 10 and the work of temporarily projecting the power line 39 and the switching member 35 from the cover members 5C and 5B of the shutter case 5 as described above. After finishing, perform the following wiring work.

  As can be seen from FIGS. 16 and 17, the terminal portion of the power supply line 39 protruding from the cover member 5C is inserted into the hole 5H of the cover member 5C, and the power supply line 39 protruding from the cover member 5C is connected to the bracket body 8A. 13 which is formed between the cover member 5C and the cover member 5C, passes through the gap S2 shown in FIG. 13, and is the thickness direction of the shutter curtain 31 formed on the lower surface (bottom surface) 5K of the cover member 5C. Exposed (protruded) from the long opening 5J. In the subsequent wiring work of the power supply line 39, as described above, the terminal portion of the power supply line 39 is connected to a power outlet disposed outdoors or indoors.

  Further, as can be seen from FIGS. 18 and 19, the terminal portion of the switching member 35 protruding from the lid member 5B is inserted into the hole 5F of the lid member 5B, and the switching member 35 protruding from the lid member 5B is attached to the bracket. 14 is a thickness direction of the shutter curtain 31 formed on the lower surface portion (bottom surface portion) 5L of the lid member 5B through the gap S1 shown in FIG. 14 formed between the main body 7A and the lid member 5B. It is exposed (projected) from the opening 5I that is long in the front-rear direction. In the subsequent wiring work of the switching member 35, as described above, the terminal portion of the switching member 35 is connected to the pulling operation member 38 disposed on one of the pair of left and right guide rails 4.

  After the above wiring work of the power supply line 39 is completed, as shown in FIG. 4, the cover member 5C has a portion 39A of the power supply line 39 exposed from the cover member 5C (FIG. A cap member 40 that opens downward is a cover member for covering (see also FIG. 17). Further, after the wiring work of the switching member 35 is completed, as shown in FIG. 4, the lid member 5 </ b> B has a portion 35 </ b> A exposed from the lid member 5 </ b> B (FIG. 14 and FIG. 14). A cap member 37 that opens downward is attached as a cover member for covering (see also FIG. 19).

  In the present embodiment, the outside of the switching member 35 formed of a wire or the like may be covered with a hollow member. In other words, the switching member 35 may be an inner wire, and the outside of the switching member 35 may be covered with an outer wire.

  As shown in FIG. 13, the diameter of the hole 5G (see also FIGS. 16 and 17) of the lid member 5C that is circular or substantially circular is the hole of the bracket body 8A that is circular or substantially circular. The diameter dimension of the hole 5G of the lid member 5C may be larger than the diameter dimension of the hole 34 of the bracket body 8A.

  The operator inserts the power supply line 39 into the hole 34 of the bracket body 8A and then inserts the power supply line 39 into the hole 5G of the lid member 5C. Since it is performed simultaneously with the work of supporting the brackets 7 and 8, the hole 5G of the lid member 5C behind the hole 34 of the bracket body 8A is difficult to see, and the terminal portion of the power line 39 inserted through the hole 34 of the bracket body 8A is It is not easy to insert through the hole 5G of the lid member 5C.

  However, by making the diameter dimension of the hole 5G of the lid member 5C larger than the diameter dimension of the hole 34 of the bracket body 8A, the terminal portion of the power supply line 39 inserted through the hole 34 of the bracket body 8A becomes the hole 5G of the lid member 5C. There is almost no need to aim for and pass through. In other words, by simply feeding the terminal portion of the power line 39 inserted through the hole 34 of the bracket body 8A toward the lid member 5C, the terminal portion of the power line 39 can be easily inserted into the hole 5G of the lid member 5C. Is possible.

  Further, as shown in FIG. 14, the diameter of the hole 5 </ b> E (see also FIGS. 18 and 19) of the lid member 5 </ b> B which is circular or substantially circular is also circular or substantially circular. The diameter dimension of the hole 5E of the lid member 5B is made larger than the diameter dimension of the hole 36 of the bracket body 7 for the same reason as described above. May be.

  As described above, when the rotation of the electric winding shaft 20 is stopped, the switching member 35 for switching on and off the brake 21D of the switch 21 is provided inside the electric winding shaft 20. The sliding operation is smoothly performed in the axial direction (left-right direction) of the electric winding shaft 20 without being interfered with the bearing portion 9.

  For this reason, according to this embodiment, even if the existing support bracket 7 and the bearing portion 9 remain, when the rotation of the electric winding shaft 20 is stopped, the brake 21D of the switch 21 by the switching member 35 is stopped. The on / off switching operation is performed smoothly.

  Although not shown in the drawings, when the manual winding shaft 6 is modified to the electric winding shaft 20, the electric shutter curtain 31 can be opened, closed, moved and stopped by remote control. Therefore, the electric window shutter device according to the present embodiment includes “open”, “closed”, and “stop” for forward rotation, reverse rotation, and rotation stop of the electric winding shaft 20. An operation device provided with a button is added.

  This operating device is the above-mentioned for controlling the drive of the electric motor 21C of the switch 21 and the operation of the brake 21D by the signal line (not shown) which is an electric cord which is a string-like member like the power line 39. However, the operating device may be connected to the control device 21B in a wireless manner.

  As shown in FIG. 4, the signal line forms one end (the end on the support bracket 8 side) of both ends of the electric winding shaft 20, as with the power supply line 39. After extending (leading out) from the end portion 21A of the opening / closing machine 21, the hole is inserted into the hole 34 of the bracket main body 8A and the hole 5G of the lid member 5C, and once protrudes outside the lid member 5C. The signal line may be inserted through the hole 5H of the lid member 5C to pass through the gap S2 (see FIG. 13) between the bracket body 8A and the lid member 5C. Further, as shown in FIG. 4, the signal line forms the other end (the end on the support bracket 7 side) of the both ends of the electric winding shaft 20, as with the switching member 35. After extending from the shaft end portion 25A, the hole is inserted into the hole 36E of the bracket body 7A and the hole 5E of the lid member 5B, and once protrudes outside the lid member 5B. Thereafter, the signal line is connected to the lid member 5B. You may make it pass the clearance gap S1 (refer FIG. 14) between the bracket main body 7A and the cover member 5B by inserting in the hole 5F.

  As described above, in the electric shutter device according to the present embodiment, the switching member 35 and the power line 39 that are string-like members extending from the switch 21 are formed on the bracket bodies 7A and 8A of the support brackets 7 and 8. The holes 36 and 34 that are the first holes and the holes 5E and 5G that are the second holes formed in the cover members 5B and 5C of the shutter case 5 are inserted into the holes 5B and 5C and project outside the cover members 5B and 5C. (Exposed) and a gap S1 formed between the bracket main bodies 7A, 8A and the lid members 5B, 5C by being inserted into the holes 5F, 5H which are the third holes formed in the lid members 5B, 5C. , S2 through the wiring structure.

  As shown in FIGS. 13 and 14, the interval between the bracket bodies 7A, 8A and the lid members 5B, 5C is narrow, and the switching member 35 and the power line 39 are formed in the holes formed in the bracket bodies 7A, 8A. When the wiring structure is inserted through the gaps 36 and 34 and directly passes through the gaps S1 and S2, the switching member 35 and the power line 39 are connected to the gaps S1 and S2 from the holes 36 and 34, respectively. Since the wiring is bent in the vertical direction (downward), the switching member 35 and the power supply line 39 are being routed in the gaps S1 and S2, or the switching member 35 and the power supply line 39 are in the gap. When the switching member 35 and the power supply line 39 extending from the switch 21 are entangled between the switch 21 and the bracket bodies 7A and 8A after being wired to S1 and S2, the work of unwinding the entanglement is easy. No.

  In contrast, in the present embodiment, as described above, the switching member 35 and the power supply line 39 are inserted through the holes 36 and 34 of the bracket main bodies 7A and 8A and the holes 5E and 5G of the lid members 5B and 5C.
