The X, Y, and Z-axis directions are perpendicular to each other.

[0010] As shown in FIGS. 2 and 3, the pair of columns 2 includes a column member 25 (a metal member) having a front surface portion 21, a rear surface portion 22, and left and right side surface portions 23, 24 (see FIG. 8) continuous with the front surface portion 21 and the rear surface portion 22, a side cover member 26 (a side cover material) attached to the side surface portion 23, a rear cover material 27 attached to the rear surface portion 22, and a resin lid member 28 (a column cap) attached to the column member 25 to cover the upper opening end portion 251 (a small opening, see FIGS. 3, 7, and 8) of the column member 25. The column member 25 is formed in a hollow rectangular cross-section and is provided along the Y-axis direction. The front surface portion 21 is disposed on the front side in the Z-axis direction with respect to the rear surface portion 22, and the side surface portion 23 is disposed inside in the X-axis direction with respect to the side surface portion 24. As shown in FIG. 1, the pivot arm 4 includes a bracket 41 pivotally attached to the column 2, a main arm 42 attached to the bracket 41, and a sub-arm 43 pivotally supported at a position radially spaced from the pivot axis of the main arm 42. A door body 5 is attached to the tips of the main arm 42 and the sub-arm 43. The pivot arm 4 rotates the main arm 42 based on the drive of a drive motor 31 (an electric motor) described later, and the sub-arm 43 rotates following the rotation of the main arm 42, thereby vertically opening and closing the door body 5 between a lower closed position and an upper open position. As shown in FIG. 1, the door body 5 is configured by arranging a lattice 52 within a door frame 51 framed on all four sides. The left and right side portions of the door frame 51 are pivotally supported at the tips of the main arm 42 and the sub-arm 43.

[0011] The column member 25, the side cover member 26, and the rear cover member 27 are made of metal, and in this embodiment, they are respectively formed by aluminum extrusion profiles. Inside the interior 25A (hollow portion) of at least one of the pair of columns 2, various internal devices such as a drive motor 31, a control device 32, an operation panel 33, an angle sensor (not shown) of the rotating arm 4, a receiver 34 for remote operation (see FIG. 7), etc., and various mechanism units 35 for opening and closing the door body 5 are installed. In the column 2 in which the above-described internal devices are incorporated, an opening 231 through which the internal devices can be inspected is formed in the side surface portion 23 of the column member 25, and a plurality of wiring openings 221 through which the wiring 9 connected to the internal devices is inserted are formed in the rear surface portion 22. This wiring 9 is covered by the rear cover member 27.

[0012] The lid member 28 is made of resin, and as shown in FIGS. 4 to 8, a main body portion 280 disposed to face the opening end portion 251 of the column member 25 in the Y-axis direction so as to cover the opening end portion 251, a peripheral piece portion 281 extending downward from the peripheral edge portion of the main body portion 280, a contact portion 282 formed to protrude downward from the main body portion 280 and contacting the opening end portion 251, a screwed fixing portion 285 screwed to the front surface portion 21 of the column member 25, and an engaging claw portion 286 engaging with an engaging hole portion 225 (see FIG. 7) formed in the rear surface portion 22 of the column member 25. The peripheral piece portion 281 has an outer peripheral piece portion 283 extending downward from the peripheral edge portion of the main body portion 280 below the contact portion 282 at a position on the outer peripheral side with respect to the contact portion 282, and an inner peripheral piece portion 284 extending downward from the peripheral edge portion of the main body portion 280 at a position on the inner peripheral side with respect to the outer peripheral piece portion 283 and the contact portion 282. The contact portion 282 is disposed between the outer peripheral piece portion 283 and the inner peripheral piece portion 284. Note that FIG. 7 is a cross-sectional view taken along the line VII-VII shown in FIG. 2, and FIG. 8 is a cross-sectional view taken along the line VIII-VIII shown in FIG. 2. The dimension of the main body portion 280 in the Z-axis direction is larger than the dimension in the Z-axis direction from the finding surface of the front surface portion 21 of the column member 25 to the finding surface of the rear cover member 27. Also, the dimension of the main body portion 280 in the X-axis direction is larger than the finding dimension of the column member 25 in the X-axis direction. The outer peripheral piece portion 283 extends longer downward and in the Y-axis direction than the contact portion 282 and the inner peripheral piece portion 284, and the length dimensions of the contact portion 282 and the inner peripheral piece portion 284 in the Y-axis direction are the same. The contact portion 282 is composed of a plurality of contact piece portions 287 that continuously extend downward from the main body portion 280 to the outer peripheral piece portion 283 and the inner peripheral piece portion 284. The plurality of contact piece portions 287 are arranged at predetermined intervals along the peripheral edge of the main body portion 280. The outer peripheral piece portion 283 is composed of an outer front piece portion 301, an outer rear piece portion 302 arranged on the rear side in the Z-axis direction with respect to the outer front piece portion 301, and left and right outer side piece portions 303, 304 continuous with the outer front piece portion 301 and the outer rear piece portion 302. The outer front piece portion 301 hangs down from the front edge of the main body portion 280, the outer rear piece portion 302 hangs down from the rear edge of the main body portion 280, and the left and right outer side piece portions 303, 304 hang down from the left and right side edges of the main body portion 280. Corners 305 are formed at the portions where the outer front piece portion 301 and the outer rear piece portion 302 are continuous with the left and right outer side piece portions 303, 304, respectively. The inner peripheral piece portion 284 is composed of an inner front piece portion 321, an inner rear piece portion 322 disposed on the rear side in the Z-axis direction with respect to the inner front piece portion 321, and left and right inner side piece portions 323, 324 continuous with the inner front piece portion 321 and the inner rear piece portion 322, and extends downward from the main body portion 280 at a position on the inner peripheral side rather than the outer peripheral piece portion 283. The inner front piece portion 321 faces the outer front piece portion 301 with a space in the Z-axis direction, the inner rear piece portion 322 faces the outer rear piece portion 302 with a space in the Z-axis direction, the inner side piece portion 323 faces the outer side piece portion 303 in the X-axis direction, and the inner side piece portion 324 faces the outer side piece portion 304 in the X-axis direction. Corners 325 are formed at the portions where the inner front piece portion 321 and the inner rear piece portion 322 are respectively continuous with the left and right inner side piece portions 323, 324. In the present embodiment, among each corner 325, a downward prevention member 70 described later is attached to a corner 325A where the inner front piece portion 321 is continuous with the inner side piece portion 324 (the inner side piece portion disposed on the outer peripheral side rather than the inner side piece portion 323). The screw-fitting fixing portion 285 protrudes downward from the inner front piece portion 321 positioned forward with respect to the engaging claw portion 286, and a screw hole 285A into which the screw 7 is screwed is formed. The engaging claw portion 286 is formed to protrude downward from the main body portion 280 between the screw-fitting fixing portion 285 and the inner rear piece portion 322 in the Z-axis direction. Note that continuous piece portions 331, 332 continuous with the left and right inner side piece portions 323, 324 are formed on the lid member 28 to enhance the member strength. In addition, a ventilation port 288 communicating the inside and the outside of the column member 25 is formed between the opening end portion 251 of the column member 25 with which the contact portion 282 comes into contact, and the main body portion 280, the outer peripheral piece portion 283, and the inner peripheral piece portion 284.

[0013] The above-described lid member 28 is attached with a housing 36 (see FIG. 7) to which a receiver 34 for remote operation is attached. The housing 36 is screwed to an attachment portion 280A provided on the main body portion 280 within a region surrounded by the inner side pieces 323 and 324 and the continuous pieces 331 and 332. Here, the receiver 34 is electrically connected to the control device 32 by a wiring 9, while being electrically connected to an antenna 37 as an external device disposed outside the support column 2 by a wiring 10. An arrangement portion 60 where the wiring 10 is disposed at a position spaced upward from the opening end portion 251 of the column member 25 is formed on the inner peripheral piece portion 284 of the lid member 28. The arrangement portion 60 has three notch grooves 61A, 61B, and 61C formed in the inner peripheral piece portion 284. The notch groove 61A is formed at a position on the inner side piece 324 side of the screwing fixing portion 285 in the inner front piece 321. The notch grooves 61A and 61B are arranged adjacent to each other at positions close to each other with the corner portion 325A therebetween. The notch grooves 61B and 61C are formed at a front position of the inner side piece 324 and are spaced apart from each other in the Z-axis direction. The interval between the notch grooves 61B and 61C is larger than the interval between the notch grooves 61A and 61B. The notch groove 61C (the other notch groove) is arranged at a position closer to the continuous piece 331 than the notch groove 61B. Each of the notch grooves 61A, 61B, and 61C has a pair of side portions and a bottom portion, and is formed to open at the lower edge of the inner peripheral piece portion 284 and extend upward. The wiring 10 from the receiver 34 is inserted into the notch groove 61C from the inside to the outside of the inner peripheral piece portion 284, passed between the inner side piece 324 and the outer side piece 304 between the notch grooves 61C and 61B, inserted into the notch groove 61B from the outside to the inside of the inner peripheral piece portion 284, inserted into the notch groove 61A from the inside to the outside of the inner peripheral piece portion 284, and disposed along the front surface portion 21 outside the column member 25 and connected to the antenna 37. The wiring 10 inserted into the notch groove 61A is led out to the outside through a ventilation port 288 formed between the outer front piece 301 and the inner front piece 321. In the present embodiment, the wiring 10 passes through all of the notch grooves 61A, 61B, and 61C. As described above, the displacement of the wiring 10 inserted into the notch grooves 61B and 61C in its longitudinal direction is suppressed. Further, a fall prevention member 70 as a fall prevention part for preventing the wiring 10 from falling downward is attached to the inner peripheral piece part 284.

[0014] As shown in FIGS. 4, 6, and 8, the fall prevention member 70 is composed of a so-called binding band and is disposed at a lower position with respect to the wiring 10 disposed in the notch grooves 61A and 61B. The fall prevention member 70 is made of resin and has a ring-shaped loop part 71 surrounding the corner part 325A and a fastening part 72 for fastening both ends of the loop part 71. The loop part 71 is formed by cutting a long body having flexibility and an engaging part along its longitudinal direction to an appropriate length and is continuously disposed in the notch grooves 61A and 61B. The fastening part 72 is integrally formed with one end of the loop part 71, and the loop part 71 is inserted from the other end side and engaged with the loop part 71. In this fall prevention member 70, the loop part 71 is placed on the opening end part 251 of the column member 25, and the wiring 10 is disposed on the loop part 71. Further, the fall prevention member 70 is attached to the corner part 325A, which is the part between the notch grooves 61A and 61B, by reducing the diameter of the loop part 71.

[0015] In the above-described flip-up door 1, the arrangement part 60 of the lid member 28 and the fall prevention member 70 constitute a wiring structure 80 through which the wiring 10 is passed between the opening end part 251 of the column member 25 and the lid member 28.

[0016] The above-described lid member 28 is attached to the column member 25 in the following procedure. First, while covering the main body portion 280 over the column member 25 from above, place a plurality of abutting piece portions 287 on the opening end portion 251. At this time, the abutting piece portion 287 between the outer front piece portion 301 and the inner front piece portion 321 abuts against the upper end of the front surface portion 21 of the column member 25, the abutting piece portion 287 between the outer rear piece portion 302 and the inner rear piece portion 322 abuts against the upper end of the rear surface cover material 27 attached to the column member 25, and the abutting piece portion 287 between the outer side piece portions 303, 304 and the inner side piece portions 323, 324 abuts against the upper ends of the side surface portions 23, 24 of the column member 25. Further, the rear portions of the left and right inner side piece portions 323, 324 among the inner peripheral piece portions 284 abut against the upper end of the rear surface portion 22 of the column member 25. Furthermore, the screw fastening portion 285 is disposed to face rearward with respect to the front surface portion 21, and the engaging claw portion 286 is disposed to face rearward with respect to the engaging hole portion 225. Next, push the lid member 28 forward to engage the engaging claw portion 286 with the engaging hole portion 225, and pass the screw 7 through the front surface portion 21 and screw it into the screw fastening portion 285. In this way, the lid member 28 is attached to the column member 25. In the attached state of the lid member 28, the left and right outer side piece portions 303, 304 are disposed to be spaced apart left and right with respect to the left and right side surface portions 23, 24, the outer front piece portion 301 is disposed to be spaced apart forward with respect to the front surface portion 21, and the outer rear piece portion 302 is disposed to be spaced apart rearward with respect to the rear surface portion 22 (the rear surface cover material 27 in this embodiment). For this reason, a forward gap (ventilation port 288) through which ventilation is possible is formed between the main body portion 280 and the outer front piece portion 301 and the upper end of the front surface portion 21, and a rearward gap (ventilation port 288) through which ventilation is possible is formed between the main body portion 280 and the outer rear piece portion 302 and the upper end of the rear surface cover material 27. Furthermore, a ventilable gap necessary for component mounting is formed between the main body portion 280 and the left and right outer side piece portions 303, 304 and the left and right side surface portions 23, 24. Note that a ventilation port may also be formed at the lower portion of the support column 2 to improve the ventilation inside the support column 2. Here, the receiver 34 for remote operation, which is attached to the lid member 28 via the housing 36, is connected to the control device 32 using a connector or the like to a wiring 9 routed to the rear side of the column member 25. Further, the wiring 10 connected to the receiver 34 and routed to the front side of the column member 25 is routed from the inside of the support column 2 to the outside via the placement portion 60 and is placed on the fall prevention member 70 to prevent direct interference with the opening end portion 251.

[0017] [Modification Example] In the above embodiment, the notch grooves 61A, 61B, and 61C are formed in the lid member 28, and the wiring 10 passes through all of them. However, the present invention is not limited to this. For example, as shown in the modification example of FIG. 9, notch grooves 62A and 62B adjacent to each other in the X-axis direction are formed only in the inner front piece portion 321 of the inner peripheral piece portion 284, and the wiring 10 may be passed through only one of the notch grooves 62A and 62B. In this case, the fall prevention member 70 is attached to the portion (the flat portion other than the corner portion 325A) between the notch grooves 62A and 62B while being continuously passed through the notch grooves 62A and 62B. In the above embodiment, the placement portion 60 is formed by the notch grooves 61A, 61B, and 61C. However, the present invention is not limited to this. For example, when processing such as drilling is allowed in the outer peripheral piece portion 283, a hole for inserting the wiring may be formed in the inner peripheral piece portion 284. In this case, since the lower portion (the portion of the inner peripheral piece portion 284) forming the hole is configured as a fall prevention portion, the configuration of the fall prevention member 70 described above is omitted. In the above embodiment, the fall prevention portion is configured by the fall prevention member 70 that is separate from the inner peripheral piece portion 284. However, the present invention is not limited to this. A protrusion may be formed on at least one of the notch grooves 61A and 61B, and the protrusion may be configured to suppress the fall of the wiring 10. In this case, since the protrusion is configured as a fall prevention portion, the configuration of the fall prevention member 70 is omitted. In the above embodiment, the placement portion 60 has the notch grooves 61A, 61B, and 61C. However, the present invention is not limited to this. When the wiring 10 is arranged such that displacement in its longitudinal direction hardly occurs, the configuration of the notch groove 61C may be omitted. In the above embodiment, the notch grooves 61A, 61B, and 61C are formed to extend upward from the lower edge of the inner peripheral piece portion 284. However, the present invention is not limited to this. For example, they may be formed to bend in a direction intersecting the Y-axis direction. In the above-described embodiment, the downward prevention member 70 is disposed on the opening end portion 251 of the column member 25 and is placed on the opening end portion 251. However, the present invention is not limited thereto. When the downward prevention member 70 is firmly attached to the inner peripheral piece portion 284 so as not to fall off, the downward prevention member 70 may be disposed at a position deviated from the opening end portion 251. In the above-described embodiment, the downward prevention member 70 is configured as a binding band that can be reduced in diameter and includes a loop portion 71 and a fastening portion 72 that are ring-shaped. However, the present invention is not limited thereto. For example, it may be configured by a C-shaped member that is continuous with the two notch groove portions 61A and 61B. Further, the downward prevention member 70 may be configured by an annular loop member that does not have the above-described fastening portion 72. In the above-described embodiment, the downward prevention portion is configured by the downward prevention member 70 attached to the lid member 28. However, the present invention is not limited thereto. For example, the downward prevention portion may be configured by a member that is attached to the opening end portion 251 of the column member 25 and disposed in the notch groove portion 61A or the like. In the above-described embodiment, the outer front piece portion 301 and the outer rear piece portion 302 of the lid member 28 are disposed at a distance from the front surface portion 21 and the rear surface cover material 27 in the Z-axis direction. However, while the outer front piece portion 301 is separated from the front surface portion 21, only a front gap (ventilation opening 288) may be formed by arranging the outer rear piece portion 302 in contact with the rear surface cover material 27. Conversely, while the outer front piece portion 301 is in contact with the front surface portion 21, only a rear gap (ventilation opening 288) may be formed by separating the outer rear piece portion 302 from the rear surface cover material 27. In this case, the wiring structure 80 may be configured on the inner rear piece portion 322 side, and the wiring 10 may be routed from the rear side of the lid member 28 to the outside. In the above-described embodiment, the left and right outer pieces 303 and 304 of the lid member 28 are spaced apart from the left and right side surfaces 23 and 24 of the column member 25 with a gap necessary for component mounting. However, by making the gap even larger to have a ventilation opening function, a ventilation opening may be formed over the entire circumference of the lid member 28. In this case, the wiring structure 80 may be configured on one side of the left and right outer pieces 303 and 304, and the wiring 10 may be routed outside from the side of the lid member 28. Also, if the lid member 28 can be attached to the column member 25 without problems, the left and right outer pieces 303 and 304 and the left and right side surfaces 23 and 24 may be in contact with each other without a gap being formed therebetween. In this case, the left-right displacement of the lid member 28 with respect to the column member 25 can be more effectively suppressed. In the above-described embodiment, the wiring 10 has been described as connecting the receiver 34 as an internal device and the antenna 37 as an external device. However, the present invention is not limited to this, and the wiring 10 may connect other internal devices and other external devices. In the above-described embodiment, the lid member 28 has a mounting structure in which the screwing fixing portion 285 is screwed and fixed to the front surface portion 21, and the engaging claw portion 286 engages with the engaging hole portion 225. However, other mounting structures may be adopted. In the above-described embodiment, the wiring structure 80 described above is configured on the column 2 of the flip-up door 1. However, in addition, the wiring structure 80 may be configured on a doorpost or the like. Further, for example, the wiring structure 80 may be configured as a structure for passing the wiring 10 between the opening end portion of a box body as a metal member and a resin lid member.

[0018] [Effects of the Invention] (1) The wiring structure of the present invention is a wiring structure in which wiring is passed between an opening end portion of a metal member having a hollow portion and a lid member attached to the metal member so as to cover the opening end portion. An internal device is disposed in the hollow portion of the metal member, the wiring connects the internal device and an external device disposed outside the metal member, a placement portion for placing the wiring is formed at a position spaced upward from the opening end portion in the lid member, and a downward prevention portion attached to the lid member or the metal member is disposed at a position below the wiring placed in the placement portion. According to the wiring structure of the present invention, since the wiring is arranged above the downward prevention portion in the arrangement portion of the lid member, it is possible to prevent the wiring from dropping to the opening end side and interfering with the opening end by the downward prevention portion. In addition, since the arrangement portion is formed in the lid member instead of the metal member, the labor of processing the metal member to pass the wiring can be eliminated. (2) In the wiring structure of the present invention, the lid member has a main body portion arranged to cover the opening end portion of the metal member, and a peripheral piece portion extending downward from the peripheral edge portion of the main body portion. The arrangement portion has at least two notch groove portions formed adjacent to each other in the peripheral piece portion. The wiring is passed through at least one of the two notch groove portions, and the downward prevention portion may be constituted by a downward prevention member passed through the two notch groove portions and attached to a portion between the two notch groove portions. According to such a configuration, since the downward prevention member is passed through the two notch groove portions formed in the peripheral piece portion and attached to a portion between the two notch groove portions, for example, compared with the case of attaching the downward prevention member to a peripheral piece portion having only one notch groove portion, the downward prevention member can be easily attached to the peripheral piece portion and the wiring can be suppressed from dropping downward in the notch groove portion. In addition, since the downward prevention member is attached to the lid member, the labor of performing processing or the like for attaching the downward prevention member to the metal member can be eliminated. (3) In the wiring structure of the present invention, the peripheral piece portion has a corner portion, the two notch groove portions are arranged sandwiching the corner portion, and the downward prevention member may be passed through the two notch groove portions and attached to the corner portion. According to such a configuration, since the portion to which the downward prevention member is attached is the corner portion of the lid member, for example, compared with the case where the downward prevention member is attached to a flat plate-like portion, the rigidity of the attachment portion can be improved and the downward prevention member can be made into a more easily attachable configuration. (4) In the wiring structure of the present invention, the arrangement portion has the two notch groove portions and other notch groove portions spaced apart from the notch groove portions, and the wiring may be passed through all of the notch groove portions. According to such a configuration, since wiring is also passed through other notch grooves, displacement in the longitudinal direction of the wiring can be suppressed. (5) In the wiring structure of the present invention, the peripheral piece portion has an outer peripheral piece portion extending downward from the main body portion and an inner peripheral piece portion extending downward from the main body portion at a position on the inner peripheral side of the outer peripheral piece portion, and the notch groove portion may be formed at the lower edge of the inner peripheral piece portion and extend upward in the inner peripheral piece portion. According to such a configuration, even when there is an outer peripheral piece portion in the lid member, the notch groove portion can be easily formed in the inner peripheral piece portion without requiring drilling or the like. Alternatively, since the outer peripheral piece portion may remain unprocessed, the external appearance design of the lid member can be maintained. (6) In the wiring structure of the present invention, a contact portion that contacts the opening end portion of the metal member is formed between the outer peripheral piece portion and the inner peripheral piece portion, and a ventilation port that communicates the inside and the outside of the metal member is formed between the opening end portion of the metal member with which the contact portion contacts, the main body portion, the outer peripheral piece portion, and the inner peripheral piece portion, and the wiring may be passed through the ventilation port. According to such a configuration, in addition to the above-described arrangement portion, it is possible to eliminate the need to form processing only for passing the wiring. (7) In the wiring structure of the present invention, the fall prevention member may be disposed on the opening end portion of the metal member. According to such a configuration, it is possible to suppress the detachment of the fall prevention member itself that prevents the wiring from falling. (8) In the wiring structure of the present invention, the fall prevention member may be formed of a ring-shaped or C-shaped member continuous with the two notch grooves. According to such a configuration, the fall prevention member can be easily attached to the portion between the two notch grooves by passing the fall prevention member through the two notch grooves. (9) In the wiring structure of the present invention, the fall prevention member may be constituted by a binding band whose ring-shaped portion can be reduced in diameter. According to such a configuration, by reducing the diameter of the ring-shaped portion of the binding band, the fall prevention member can be firmly attached to the peripheral piece portion of the lid member. (10) The flip-up door of the present invention includes a support column, a rotating arm that is rotatably attached to the proximal end side with respect to the support column, and a door body supported on the distal end side of the rotating arm. The support column includes a column member made of the metal member in the present invention described above and the lid member in the present invention described above. The support column is characterized in that the wiring structure in the present invention described above is configured therein. According to such a configuration, a flip-up door capable of exerting the operational effects of the wiring structure of the present invention described above can be configured.
