Description

TECHNICAL FIELD The present invention relates to a column and flip-up gate in which various devices are installed.

BACKGROUND ART Conventionally, in an electric garage door that opens and closes an entrance/exit of a garage, a pillar (column body) that supports a door body via an arm so as to be able to open and close vertically is known (see Patent Document 1). This support is formed into a hollow shape by engaging a deep groove-shaped support main body with a substantially U-shaped cross section and a shallow groove-shaped cover body with a substantially U-shaped cross section. In addition, an opening for inspection is formed in this pillar at a position facing the built-in equipment such as a control device and a receiver installed inside the pillar, and this opening is covered with a removable lid.

Utility Model Publication No. 62-149583

By the way, in the pillar described in Patent Document 1, wiring work for various built-in devices installed inside the pillar must be done by inserting fingers or tools into the inside of the pillar through an opening in the pillar, and the inside of the pillar is dark. Since the working range is narrow within the opening size, it is difficult to improve wiring workability.
Furthermore, it is desirable that the lid (covering material) that closes the opening of the support column be installed so that it does not flap due to the influence of wind or the like.

An object of the present invention is to provide a column and a flip-up gate that can improve wiring workability and suppress flapping of a cover material that closes an opening.

The column body of the present invention includes a column member configured such that equipment can be installed therein, and the column member has a front part, a rear part, and left and right side parts, and one of the left and right side parts. An opening through which the device can be inspected is formed in the side surface of the device, a wiring port through which a wire connected to the device is inserted is formed in the rear surface, and a wiring port is formed in the one side surface to close the opening. A wiring cover material is attached to the rear surface portion to cover the wiring led out from the wiring port, and the one side surface portion has a front side formed closer to the front surface portion than the opening portion. The cover material has an engaging portion, and the cover material includes a cover main body portion disposed along the one side surface portion, and a fixing portion continuous with the cover main body portion and disposed along the rear surface portion. The cover main body part has a cover engaging part that engages with the front engaging part, and the fixing part is fastened to the rear part by a fixing tool.

The flip-up gate of the present invention includes a column constituted by the above-described column body of the present invention, a rotating arm whose proximal end is rotatably attached to the column, and a tip end of the rotating arm. It is characterized by comprising a supported door body.

According to the present invention, it is possible to provide a column and a flip-up gate that can improve wiring workability and suppress flapping of the cover material that closes the opening.

The procedure for attaching the column cap 28 will be explained below.
First, as shown in FIGS. 7(A) and 7(B), the cap main body portion 281 is placed over the upper end of the pillar material 25, and the plurality of contact pieces 287 are placed on the open end portion 251. At this time, the contact piece 287 between the outer front piece 301 and the inner front piece 321 contacts the upper end of the front face 21 of the column 25, and the contact piece 287 between the outer front piece 301 and the inner front piece 322 contacts the upper end of the front face 21 of the column 25, and The contact piece 287 faces the upper end of the cover piece 273 of the wiring cover 27 attached to the pillar 25, and the contact piece 287 between the outer piece 303 and the inner piece 323 faces the upper end of the cover piece 273 of the wiring cover 27 attached to the pillar 25. The abutment piece 287 that is in contact with the upper end of the side face 23 and between the outer piece 304 and the inner piece 324 abuts on the upper end of the side face 24 of the column 25 . In addition, the left and right inner pieces 323 and 324 of the inner peripheral piece 284 abut against the upper end of the rear surface 22 of the column 25. Further, the screw fixing part 285 is arranged rearwardly facing the front part 21, and the engaging claw part 286 is arranged rearwardly facing the engaging hole part 225. Next, the pillar cap 28 is pushed forward to engage the engaging claw portion 286 with the engaging hole portion 225, and the screw 10 is passed through the front portion 21 and screwed into the screw fixing portion 285. In this way, the pillar cap 28 is attached. In the installed state, the left and right outer pieces 303 and 304 are spaced apart laterally from the left and right side parts 23 and 24, and the outer front piece 301 is spaced apart from the front part 21. The outer rear piece portion 302 is spaced apart from the rear surface portion 22 (in this embodiment, the wiring cover material 27). Therefore, a ventilation-enabled front gap 11 is formed between the cap body 281, the outer front piece 301, and the upper end of the front face 21, and the gap 11 between the cap body 281, the outer rear piece 302, and the wiring cover 27 is formed. A rear gap 12 that allows ventilation is formed between the upper end and the upper end. Furthermore, a gap necessary for attaching the parts is formed between the cap main body 201 and the left and right outer pieces 303 and 304 and the left and right side surfaces 23 and 24. Note that a ventilation hole may be formed separately at the lower part of the support column 2 to improve the ventilation inside the support column 2. Further, a receiver for remote control (not shown) may be attached to the pillar cap 28.

[Modified example]
In the embodiment, the support column 2 includes an upper cover material 261 and a lower cover material 262, but it may include three or more cover materials, or one cover extending long in the Y-axis direction. If the cover material can be attached, the one cover material may be provided.
In the embodiment described above, the abutting projections 268 are formed on the upper cover material 261 and the lower cover material 262, but this structure may be omitted.
In the embodiment described above, the wiring cover material 27 has the fixed cover part 275, but this structure may be omitted.
In the embodiment described above, the outer front piece part 301 and the outer rear piece part 302 of the pillar cap 28 are arranged apart from the front part 21 and the wiring cover material 27 in the Z-axis direction, but the outer front piece part 301 Only the front gap 11 may be formed such that the outer rear piece 302 is in contact with the wiring cover material 27 while the outer rear piece 302 is spaced apart from the front part 21 . Conversely, the outer front piece 301 may be in contact with the front face 21, while the outer rear piece 302 may be spaced apart from the wiring cover material 27 to form only the rear gap 12.
In the embodiment described above, the left and right outer pieces 303 and 304 of the column cap 28 are arranged apart from the left and right side surfaces 23 and 24 of the column member 25 to form a gap necessary for mounting the parts. Alternatively, the ventilation hole may be formed over the entire circumference of the pillar cap 28 by making the gap larger and having a ventilation hole function. Furthermore, even if the left and right outer pieces 303 and 304 are placed in contact with the left and right side surfaces 23 and 24 of the column member 25, the column cap 28 can be attached without any problem. In this case, it is possible to more effectively suppress the left-right positional deviation of the pillar cap 28 with respect to the pillar material 25.
In the embodiment described above, the pillar cap 28 has a mounting structure in which the screw fixing part 285 is screwed and fixed to the front part 21, and the engagement claw part 286 engages with the engagement hole 225. Other mounting structures may be employed.
