Description

  The present invention relates to a cover member, and more particularly to a cover member that covers a lead-in hole for drawing a wiring extending from an electrical facility such as a solar panel installed on an inclined roof into a building.

  Conventionally, as a technique for drawing a wiring extending from an electric facility such as a solar panel installed on a roof into a building, for example, in Patent Document 1, a wiring panel is inserted through a waterproof panel constituting the roof. There is disclosed a roof penetration structure for inserting wirings, which is provided with a pipe member, and has a rising portion protruding upward from the surface of the waterproof panel and a collar portion that can be in close contact with the surface of the waterproof panel.

JP-A-7-193948

However, since the pipe member described in Patent Document 1 is open in the vertical direction, rainwater or the like may enter from above.
Moreover, since the above-mentioned pipe member is provided with the rising part which protrudes from the surface of a waterproof panel, there exists a problem that a height dimension becomes large and is inferior to layout property. Moreover, in order to insert the wiring into the pipe member, it is necessary to raise the wiring from the roof surface and bend it further downward, which is complicated and the wiring may be damaged by the bending. is there.

Furthermore, in recent years, the number of solar panels installed on one roof tends to increase in order to increase the utilization ratio of natural energy in the power used due to the demand for CO2 emission reduction. Therefore, the number of solar panel cables drawn into the back of the hut increases, but the pipe member described in Patent Document 1 has only one hole formed in the vertical direction, so the first cable is connected to the pipe member. When the second cable is inserted after inserting the first cable, the first cable becomes an obstacle and the workability is poor. Further, if the diameter of the pipe member is increased, the cable is less likely to get in the way, but since the opening area is increased, there is a risk that the strength of the roofing material is reduced and the risk of water leakage increases. Moreover, in the method of bundling all the cables and inserting them through the pipe member at the same time, the work procedure is restricted.
That is, the pipe member described in Patent Document 1 does not have a structure suitable for drawing a large number of cables.

  The present invention has been made to solve such a problem, and an object of the present invention is to provide a cover member that can reduce a height dimension and easily draw a large number of wires into a building.

The present invention is a cover member installed in a drawing hole provided on an inclined surface for drawing a cable of an electrical facility indoors, and has an insertion hole for inserting the cable at a position corresponding to the drawing hole. A flat plate portion, a cover portion that covers the upper portion of the insertion hole and has an opening that opens downward in the inclined direction, and a seal portion that is provided at a peripheral edge portion on the back surface side of the flat plate portion, the cover portion may have a plurality of passages which are separated from each other, said plurality of passages is provided with three passages arranged in parallel in a direction orthogonal to the tilting direction, on both sides of the passage of said three passages The upper end portion in the inclination direction of the section is curved so as to go around the upper inclination direction of the central passage portion, and the upper end portion in the inclination direction of the three passage portions is located at the apex of the equilateral triangle with the center point Three fronts arranged to be Respectively into the insertion hole is a cover member, characterized in that in communication.

According to this structure, since it has the some channel | path part divided mutually, a some cable can be disperse | distributed and inserted in each channel | path part. Therefore, when one cable is inserted, other cables do not get in the way, so that the cable insertion operation is facilitated. Moreover, since the opening part of the cover part is provided downward in the inclination direction, the height dimension of the cover member can be suppressed.
Further, according to this configuration, the end portions on the upper side in the inclination direction of the passage portions on both sides of the three passage portions are curved so as to go around the upper side in the inclination direction of the central passage portion, and the three passage portions Since the end on the upper side in the inclination direction communicates with the three insertion holes arranged so that the center point is the position of the apex of the regular triangle, the three insertion holes can be efficiently arranged in a narrow range, The diameter of the drawing hole can be reduced.

  Further, the present invention has a holding portion that is erected at a position that is a surface of the flat plate portion and is spaced downward from the cover portion in the inclination direction, and the holding portion is a through-hole for inserting the cable. It is preferable to have a configuration having a portion.

  According to such a configuration, when the cable inserted through the cover portion is bent downward, the cable that tends to float upward near the opening of the cover portion can be suppressed. For this reason, the cable does not float up and has a reverse slope, and water leakage due to water transferred from the cable can be reliably prevented.

  Moreover, it is preferable that the upper end in the inclination direction of the passage portion is constituted by a wall surface that is curved in the vertical direction, and is configured to be smoothly continuous with the peripheral edge portion of the insertion hole.

  According to such a configuration, the end on the upper side in the inclination direction of the passage portion is configured by a wall surface that is curved in the vertical direction. Therefore, when the cable is inserted into the passage portion, the tip of the cable follows the wall surface that is curved in the vertical direction. Then, it bends downward and comes out of the drawing hole through the insertion hole. Moreover, since the edge part of the inclination direction upper side of a channel | path part is following the peripheral part of the insertion hole smoothly, the edge part of a cable is not caught in an insertion hole or a drawing hole. Therefore, it is possible to easily pull out the cable from the drawing hole simply by pushing the cable into the passage portion.

  Moreover, it is preferable that this invention is set as the structure further equipped with the cylindrical protrusion part which protrudes from the back surface of the said flat plate part, enters the said drawing hole, and surrounds the circumference | surroundings of the said insertion hole.

  According to this configuration, since the inner peripheral surface of the drawing hole is covered with the protruding portion, the cable does not contact the inner peripheral surface of the drawing hole, and damage to the cable can be suppressed.

  ADVANTAGE OF THE INVENTION According to this invention, while reducing a height dimension, the cover member which can draw in many wiring in a building easily can be provided.

In addition, the mounting rail 19 is provided in the inclined surface 11, and the solar panel 12 is being fixed to the mounting rail 19 via mounting tools, such as the volt | bolt B. As shown in FIG.

FIG. 3 is an exploded perspective view showing an installation state of the cover member and the lead-in hole. 4A is a perspective view of the cover member as viewed from above, and FIG. 4B is a perspective view of the cover member as viewed from below. FIG. 5A is a plan view of the cover member, and FIG. 5B is a bottom view of the cover member. 6A is a cross-sectional view taken along line AA in FIG. 5A, and FIG. 6B is a cross-sectional view taken along line BB in FIG.
As shown in FIGS. 2 to 6, the cover member 20 is a member that covers the lead-in hole 15 and is waterproof, and is integrally molded by, for example, injection molding using a resin material. The cover member 20 includes a flat plate portion 21, a cover portion 22, a protruding portion 23, a holding portion 24, and a seal portion 25. The cover member 20 is screwed to the inclined surface 11.

  The flat plate portion 21 is a flange-shaped portion that covers the periphery of the drawing hole 15. The flat plate portion 21 has an insertion hole 21 a for inserting the cable 12 b at a portion corresponding to the drawing hole 15. The peripheral edge portion 21b on the upper side in the inclination direction of the flat plate portion 21 is formed in an arc shape. Therefore, even if rainwater or the like flows on the inclined surface 11, rainwater can flow down to the left and right sides of the cover member 20 along the peripheral edge portion 21 b and away from the drawing hole 15.

  As shown in FIGS. 3 to 5 (mainly FIG. 5), the insertion hole 21a is formed, for example, in a shape in which a plurality of arcs are combined. In the present embodiment, the lower peripheral edge of the insertion hole 21a is formed in a semicircular shape with a single arc r1 (see FIG. 5), and the upper peripheral edge of the insertion hole 21a is three arcs r2. , R3, r4 (see FIG. 5). Of the three arcs r2, r3, r4, the center arc r3 extends to the upper side in the inclination direction than the two arcs r2, r4 on both sides.

  As shown in FIGS. 5A and 5B, the cover portion 22 is a portion that covers the upper side of the insertion hole 21a and forms a passage through which the cable 12b is inserted. In the present embodiment, the cover portion 22 is three tunnel-shaped portions formed in parallel to each other, and includes a first passage portion 221, a second passage portion 222, and a third passage portion 223. . The first to third passage portions 221, 222, and 223 are partitioned from each other (see FIG. 6A), and openings 221 a, 222 a, and 223 a for inserting the cable 12 b are provided on the lower side in the inclination direction. Each is formed. Upper end portions 221b, 222b, and 223b of the first to third passage portions 221, 222, and 223 are closed by wall surfaces that are curved in the vertical direction, and an inclination of the insertion hole 21a provided on the lower side thereof. It smoothly continues to the three arcs r2, r3, r4 forming the peripheral edge on the upper side in the direction.

Here, the structure of the end portion 222b on the upper side in the inclination direction of the second passage portion 222 will be described with reference to FIG.
As shown in FIG. 2 (b), the end 222b on the upper side in the inclination direction of the second passage portion 222 is configured by a wall surface curved in the vertical direction, and the peripheral edge on the upper side in the inclination direction of the insertion hole 21a is formed. It smoothly continues to the arc r3. Therefore, when the cable 12 b is inserted from the opening 222 a of the second passage portion 222, the tip of the cable 12 b comes into contact with the end portion 222 b on the upper side in the inclination direction of the second passage portion 222. When the cable 12b is further pushed in in this state, the tip of the cable 12b is guided along the end portion 222b, bent downward, and comes out of the insertion hole 21a. Therefore, the operation of inserting the cable 12b through the cover member 20 (through the drawing hole 15) is facilitated.
Since the first passage portion 221 and the third passage portion 223 also have substantially the same structure as the second passage portion 222, detailed description thereof is omitted.

  As shown mainly in FIG. 4B, the protruding portion 23 is a cylindrical portion that fits into the drawing hole 15, and protrudes from the back surface of the flat plate portion 21. The protruding portion 23 covers the inner peripheral surface of the drawing hole 15. Thereby, it is possible to suppress the cable 12b from rubbing against or being caught by the inner peripheral surface of the lead-in hole 15. Further, the protruding portion 23 functions as a positioning portion when the cover member 20 is installed in the drawing hole 15.

  As shown in FIGS. 2 to 6, the holding part 24 is a gate-shaped part for preventing the cable 12 b from being lifted. The holding portion 24 is erected on the upper surface of the flat plate portion 21 at a position spaced apart from the cover portion 22 in the downward direction of the inclination. The holding portion 24 has three through portions 24 a, 24 b, and 24 c corresponding to the first to third passage portions 221, 222, and 223 of the cover portion 22. As shown in FIG. 6B, the holding portion 24 is formed to have a smaller height than the openings 221a, 222a, and 223a (see FIG. 6A) of the cover portion 22.

As shown in FIGS. 3, 4 (b), and 5 (b), the seal portion 25 is a member that is attached to a peripheral portion excluding the lower side in the inclined direction of the back surface of the flat plate portion 21, for example, a tape-like butyl rubber (Butyl tape) etc. The seal portion 25 is formed in an inverted U shape in plan view, and is sandwiched between the flat plate portion 21 and the base plate 11a to prevent rainwater or the like from entering. In addition, the screw fastening part is waterproofed with butyl rubber.
In addition, arrangement | positioning of the seal part 25 is not limited to this, You may arrange | position the seal part 25 over the perimeter of the back surface of the flat plate part 21. FIG.

Further, since the first passage portion 221, the second passage portion 222, and the third passage portion 223 are arranged in parallel in the Y direction, a large number of cables 12b can be dispersed and arranged in the Y direction. The height dimension of the member 20 can be suppressed.

  Further, end portions 221b, 222b, and 223b on the upper side in the inclination direction of the first to third passage portions 221, 222, and 223 are respectively closed by wall surfaces that are curved in the vertical direction, and an insertion hole 21a provided on the lower side thereof. Since the cable 12b is inserted from the openings 221a, 222a, and 223a, the cable 12b in contact with the end portions 221b, 222b, and 223b is formed. It is guided along the curved wall surface, bent toward the insertion hole 21a, and comes out of the drawing hole 15 through the insertion hole 21a. At this time, since the end portions 221b, 222b, and 223b are smoothly continuous with the arcs r2, r3, and r4, the cable 12b is not caught by the flat plate portion 21 and the inclined surface 11. That is, the cable 12b can be easily pulled out from the lead-in hole 15 simply by pushing the cable 12b into the first to third passage portions 221, 222, and 223.

Moreover, since the cover member 20 is provided with the holding | suppressing part 24, the floating of the cable 12b can be suppressed.
More specifically, if the holding portion 24 is not provided, if the cable 12b is bent downward at the end portions 221b, 222b, 223b on the upper side in the inclination direction of the first to third passage portions 221, 222, 223, As a result of the reaction, the cable 12b rises in the vicinity of the openings 221a, 222a, and 223a of the first to third passage portions 221, 222, and 223. If the cable 12b becomes a reverse slope due to the rising (the drawing hole 15 side is lowered), rainwater or the like easily enters the drawing hole 15 through the cable 12b.
In the present embodiment, since the gate-shaped restraining portion 24 is disposed at a position spaced downward from the opening portions 221a, 222a, and 223a in the tilt direction, the cable 12b has a reverse slope while preventing the cable 12b from rising. Can be suppressed (see FIG. 2A).

In addition, since the cover member 20 has an arc-shaped peripheral edge 21b on the upper side in the inclination direction of the flat plate portion 21, rainwater or the like flowing on the inclined surface 11 is moved to the left and right of the cover member 20 along the peripheral edge 21b. Can flow down. Further, since the cover member 20 includes the seal portion 25,
It is possible to prevent rainwater or the like from entering between the inclined surface 11 and the flat plate portion 21.

The point formed in this way is different from the cover member 20 according to the above-described embodiment.

  According to such a configuration, the first to third passage portions 221, 222, and 223 are formed so as to taper toward the distal end side (the upper side in the inclined direction), so that the insertion hole 21a and the protruding portion 23 are made smaller. As a result, the lead-in hole 15 can be made small. Therefore, it is possible to reduce the size of the cover member 20A, and it is possible to suppress a decrease in strength of the roof 10 due to the lead-in hole 15.

FIG. 8 is a plan view of a cover member according to a second modification.
As shown in FIG. 8, the cover member 20 </ b> B according to the second modification is curved so that the first and third passage portions 221 and 223 on both sides of the cover portion 22 wrap around the distal end side of the central second passage portion 222. In the above-described embodiment, the flat plate portion 21 is formed with three insertion holes 21c, 21d, and 21e corresponding to the first to third passage portions 221, 222, and 223, respectively. This is different from the cover member 20.

In the second modification, the three insertion holes 21c, 21d, and 21e are arranged at positions where the center points are the vertices of the regular triangle. Further, the inner circumferential circle of the cylindrical protrusion 23 is formed in a size that circumscribes the insertion holes 21c, 21d, and 21e. Thereby, the three insertion holes 21c, 21d, and 21e can be efficiently arranged to further reduce the protruding portion 23, and thus the drawing hole 15 can be reduced.
Further, in the second modification, not only the first to third passage portions 221, 222, and 223 but also the insertion holes 21c, 21d, and 21e are partitioned, so that a large number of cables 12b can be wired more easily. it can.
