Description

The present invention relates to a bird prevention device.

The present applicant has previously proposed a bird-proof device as shown in Figs. 14 and 15 (see Patent Document 1).
The bird-proof device shown in Figures 14 and 15 prevents birds from entering the space between the upper surface _Y1 of the roof Y and the underside of the installed solar panel S, and comprises a bird-proof net 51 and bird-proof net holders 52 arranged at a predetermined interval pitch.
The net holder 52 has an L-shaped receiving piece 54 at its upper end for receiving the edge frame S ₂ of the solar panel S, and the L-shaped receiving piece 54 is attached to the upper end of a bolt rod 57 .
A bolt rod 57 is screwed into a screw hole 55 of a base member 56 so as to be freely threaded, thereby enabling adjustment of the height dimension from the underside of the base member 56 to the L-shaped receiving piece 54. The upper end of the bolt rod 57 and the underside of the receiving piece 54 are connected by a mounting piece 59 and a rivet 60. 58 is a lock nut.

JP 2019-058078 A

It has become clear that the bird-proof net holder 52 shown in Figs. 14 and 15 described above has the following problems at work sites.
In other words, the vertical distance (height) _H2 between the roof top surface _Y1 and the underside of the edge frame _S2 of the solar panel S varies greatly from work site to work site, so the one length of bolt rod 57 shown in Figures 14 and 15 cannot be used for all work sites.
It was necessary to carry a large number of different types of bolts 61 with receiving pieces, each consisting of an L-shaped receiving piece 54 and a bolt rod 57, of different lengths to the work site as spares.
In this way, depending on the situation at the work site - the size of the vertical spacing dimension _H2 - part rearrangement work frequently occurred, which resulted in a significant impact on the progress of the construction work.
Furthermore, in order to extend or retract the bolt rod 57 in Figs. 14 and 15, a work tool such as a wrench is required, which impedes work efficiency when working at high altitudes.

The present invention aims to solve these problems and provide a bird-proof device equipped with a bird-proof net holder that can flexibly accommodate different vertical clearance dimensions between the roof top surface and the solar panel edge frame for each work site. Another aim is to reduce (or eliminate) the use of tools such as wrenches at bird-proof device installation work sites where a lot of work is done at height, making the work safer and more efficient.

Therefore, the present invention provides a bird-prevention device comprising: a metal bird-prevention net that shields the gap between the roof top surface and the underside of a solar panel mounted on the roof top surface in order to prevent birds from entering the space between the roof top surface and the underside of the solar panel; and a bird-prevention net holder that is installed at a specified interval along the edge frame of the solar panel. The bird-prevention net holder comprises: a lower plate portion that is placed on the roof top surface; a horizontal upper plate portion that forms a space of a specified height above the lower plate portion and has vertical screw holes passing through it; and a base metal fitting having a vertical plate portion and a base metal fitting having a vertical plate portion and a base metal fitting having a vertical screw hole extending through the edge frame of the solar panel. The device is equipped with an L-shaped frame support member that supports the lower surface and has a bird netting hook; a horizontal manual rotating body that is held by the frame support member so as to be rotatable about a vertical axis and has a through hole in the up-down direction with a hexagonal recess on the upper surface; and a hexagonal bolt that is removably inserted from above into the through hole of the manual rotating body and has a hexagonal head that fits into the hexagonal recess; the hexagonal bolt is screwed into the screw hole of the base metal fitting, and by manually rotating the manual rotating body, the height dimension from the lower surface of the lower plate of the base metal fitting to the upper surface of the frame support member that abuts against the edge of the frame can be freely adjusted.

The frame receiving member has an insertion holding space into which the manual rotating body is inserted obliquely from below and is stored and held horizontally.
Further, the frame support member has a horizontal frame supporting wall portion that abuts against the edge frame, and a lower folded piece portion that is folded and formed so as to protrude downward from the frame supporting wall portion, and the lower folded piece portion is provided with a rotating body supporting horizontal wall portion having an arc-shaped notch portion, and has a slit-shaped window portion at a position opposite to the notch portion into which a part of the rotating body is inserted; the manual rotating body has a large diameter lower disc portion and a small diameter upper disc portion, and a circular groove is formed between the large diameter lower disc portion and the small diameter upper disc portion; and the manual rotating body is held in the insertion holding space by engaging the inner peripheral edge of the arc-shaped notch portion with the circular groove.

Moreover, the frame receiving member is formed by punching and bending a single metal plate.
Moreover, the frame receiving member is made of synthetic resin.
Furthermore, the manual rotating body has small uneven teeth formed on its outer peripheral surface to prevent fingers from slipping; a bolt rod is protruded horizontally outward from the vertical plate portion of the base metal fitting, and the bolt rod is passed through the mesh of the bird-proof net and a nut is screwed into it.When the bird-proof net is fixed in place with the bird-proof net clamped between the vertical plate portion and the nut, the bird-proof net comes into contact with the small uneven teeth on the outer peripheral surface of the manual rotating body, thereby providing an anti-rotation function for the manual rotating body.

According to the present invention, the manual rotating body can be rotated by the worker with his or her fingers, eliminating the need to use wrenches or other tools when working at height, ensuring safety, and also allowing the height dimension from the underside of the base metal fitting to the top surface of the frame support member to be adjusted quickly and easily, resulting in excellent work efficiency.
Furthermore, because the hexagonal bolt can be freely inserted and removed from the manual rotating body, if it is discovered after arriving at a remote work site that the required bolt length differs, it can be easily dealt with by purchasing only the desired hexagonal bolt at a hardware store, home improvement store, etc., near the work site. In other words, even if the gap between the edge frame of the solar panel and the upper surface of the roof varies in size at each unknown work site, it can be dealt with quickly and easily by replacing the hexagonal bolt, and construction delays can be avoided.

The present invention will be described in detail below based on the illustrated embodiments.
1 to 9, in the bird-proofing device of the present invention, a metal bird-proofing net 2 is attached to cover a gap 3 between an edge frame ₁ of a solar panel S and the roof top surface _Y1 in order to prevent birds (which in the present invention includes "bats") from invading a space Z between the roof top surface _Y1 and the underside of a solar panel S installed on the roof top surface Y1 (see Figs. 1 and 8).

Reference numeral 10 denotes a bird-proof net holder which is installed at predetermined intervals along the edge frame 1 of the solar panel S.
This bird-proof net holder 10 comprises a lower base metal fitting 11, an upper frame receiving member 12, a manual rotating body 13, and a hexagonal bolt 14.
The base metal fitting 11 has a lower plate portion 5 that is placed on the roof upper surface _Y1 , an upper plate portion 6 that forms a space 4 of a predetermined height above the lower plate portion 5 and has a screw hole 7 extending therethrough in the vertical direction, and a vertical plate portion 8.
The frame support member 12 supports the lower surface 1A of the edge frame 1 of the solar panel S, has a bird-proof netting hook piece 9, and is L-shaped when viewed from the side.
The manual rotating body 13 is held by the frame receiving member 12 so as to be rotatable about a vertical axis, and has a hexagonal recess 15 on the upper surface, and a through hole 16 in the vertical direction.

In addition, the hexagonal bolt 14 in the present invention refers to a standard bolt having a hexagonal head 14A. In other words, it is a standard product that can be easily obtained at hardware stores, home improvement centers, etc.
The hexagonal bolt 14 is inserted from above into the through hole 16 of the manual rotating body 13 so as to be removable, and the hexagonal head 14A fits into the hexagonal recess 15, so that the hexagonal bolt 14 and the manual rotating body 13 always rotate as one unit.
And, the hexagonal bolt 14 (from its bottom end) is screwed into the screw hole 7 of the base metal fitting 11. Reference numeral 25 denotes a rotation-preventing nut. By manually rotating the manual rotating body 13 (by an operator), the height dimension _H10 from the lower surface 5A of the lower plate portion 5 of the base metal fitting 11 to the edge frame-contacting upper surface portion 12A of the frame receiving member 12 can be freely adjusted (see Figs. 1, 6 and 7).

Next, in each of Figures 10, 11, and 12, as shown in (A) → (B) → (C) in sequence, the frame support member 12 has an insertion holding space 20 in which the manual rotating body 13 is inserted from diagonally downward as shown by the arrow X and stored and held horizontally (see Figure 13).

A more detailed description will now be given of the frame support member 12. As shown in Figures 1, 13, 10, 11 and 12, the frame support member 12 has a horizontal frame support wall portion 12B that abuts against the lower surface 1A of the edge frame 1 of the solar panel S. The upper surface of this horizontal frame support wall portion 12B corresponds to the frame abutment upper surface portion 12A.
The frame support wall 12B has a lower bent piece 12C formed by bending the frame support wall 12B downward. The lower bent piece 12C has a rotor support horizontal wall 12E having an arc-shaped notch 12D.
In addition, a vertical wall portion 12F is bent so as to be parallel to and opposite the lower bent piece portion 12C, and this vertical wall portion 12F is formed with a slit-shaped window portion 12G, into which a part of the rotating body 13 is inserted, opposite the arc-shaped cutout portion 12D.

As shown in Figures 4, 8, 9, 10, etc., the manual rotating body 13 has a large-diameter lower disk portion 13A and a small-diameter upper disk portion 13B, and a circular recess 13C is formed between the large-diameter lower disk portion 13A and the small-diameter upper disk portion 13B.
1, 2, 8, and 10 to 12, the inner peripheral edge of the arc-shaped cutout 12D is engaged with the annular groove 13C of the manual rotating body 13. By this engagement, the manual rotating body 13 is held in the insertion holding space 20 of the frame receiving member 12 so as to be freely rotatable.
As can be seen from FIGS. 1 to 13, the frame receiving member 12 is a simple member formed by punching and bending a single sheet metal (thin metal material).

By the way, it is also preferable to use synthetic resin as the material of the frame receiving member 12. When made of synthetic resin, the shape of the frame receiving member 12 is the same as that of a metal plate, but the thickness is increased to ensure strength.
The manual rotating body 13 is preferably made of synthetic resin. The manual rotating body 13 has an outer peripheral surface 13D formed with small uneven teeth 21 (knurled) to prevent fingers from slipping.

1, 8 and 9, the metal bird-proof net 2 is in the shape of a long strip that is long from left to right, and the bird-proof net hook piece 9 of the L-shaped frame support member 12 is hooked (engaged) onto the horizontal wire at the upper edge 2A of the net, maintaining the upper edge 2A of the net in a vertical position.
The width _W9 of the bird-proof net hooking piece 9 is set smaller than the mesh size _W2 of the bird-proof net 2 so that the hooking piece 9 can be easily inserted into the mesh of the bird-proof net 2 and locked therein.

1 to 8, a bolt rod 17 is provided to protrude horizontally outward from the vertical plate portion 8 of the base metal fitting 11. This bolt rod 17 is passed through the mesh of the bird-proof net 2 and a nut 18 is screwed in, so that the bird-proof net 2 is clamped between the vertical plate portion 8 and the nut 18 and fixed in place.
With the bird-proof net fixed in this state, as shown in Figures 8 and 9, the bird-proof net 2 abuts (engages) with the small uneven teeth 21 on the outer circumferential surface 13D of the manual rotating body 13, thereby providing an anti-rotation function for the manual rotating body 13.
In the installation (setting) work, a plurality of bird-proof net holders 10 are arranged (fixed) at a predetermined pitch on the left and right sides, and then the bird-proof net 2 is attached.

As shown in Figure 8, when the bird net 2 is fixed in place by screwing in the nut 18 in a later process, the vertical wires 2C of the bird net 2 are engaged with the small uneven teeth 21 on the outer circumferential surface 13D of the manual rotating body 13 as shown in Figure 9, so that the manual rotating body 13 is securely prevented from rotating (and without the need for a separate small anti-loosening member).

In addition, in this invention, the term "birds" and "bird species" used to describe bird control are defined to include bats and small mammals.

As described above in detail, the present invention provides a bird-proof device comprising: an edge frame ₁ of a solar panel S; a metal bird-proof net 2 for shielding a gap 3 between the edge frame ₁ of the solar panel S and the roof top surface _Y1 ; and bird-proof net holders 10 installed at predetermined intervals along the edge frame 1 of the solar panel S, in order to prevent birds from invading a space Z between the roof top surface Y1 and the underside of a solar panel S installed on the roof top surface Y1. a base fitting ₁₁ having a lower plate 5 to be placed on the solar panel S, a horizontal upper plate 6 having a vertical screw hole 7 formed therethrough and a lower plate 8 forming a space 4 of a predetermined height above the lower plate 5; an L-shaped frame support member 12 which supports the lower surface 1A of the edge frame 1 of the solar panel S and has a bird net hook 9; a vertical through hole 16 which is held by the frame support member 12 so as to be rotatable about a vertical axis and has a hexagonal recess 15 on its upper surface. and a hexagonal bolt 14 having a hexagonal head 14A that is removably inserted from above into the through hole 16 of the manual rotating body 13 and fits into the hexagonal recess 15. The hexagonal bolt 14 is screwed into the screw hole 7 of the base metal fitting 11, and the height dimension H 10 from the lower surface 5A of the lower plate portion 5 of the base metal fitting 11 to the edge frame abutting upper surface portion 12A of the frame receiving member 12 can be freely adjusted by manually rotating the manual rotating body _13. Therefore, a worker can easily, quickly, and safely rotate the manual rotating body 13 with his fingers (or with the fingers of a gloved hand) to adjust the height dimension H ₁₀ at a high work site without needing a work tool such as a spanner. Therefore, the danger of the work can be significantly reduced. In addition, since the height dimension _H10 of the underside 1A of the edge frame 1 varies significantly depending on the work site, it is often the case that when arriving at the site to perform work, the length of the bolts prepared in advance (brought with you) is different and they cannot be used. However, even in such cases, the standard hex bolt 14 with the hex head 14A of the present invention can be easily obtained at local hardware stores, home improvement centers, etc. of the appropriate length, so that by simply replacing the hex bolt 14, it is possible to quickly and easily accommodate the height dimension _H10 of the edge frame 1 of the solar panel S from the roof top surface _Y1 at the site.
In this way, by simply changing the bolts, delays in work can be prevented and work can be speeded up. Also, the upper edge 2A of the bird-proof net 2 is securely fixed and held.

The frame support member 12 also has an insertion and holding space 20 into which the manual rotating body 13 is inserted from an obliquely downward direction and stored and held horizontally, so that the manual rotating body 13 can be easily inserted and held in the frame support member 12. During subsequent use, even if the manual rotating body 13 is subjected to force from the edge frame 1, the manual rotating body 13 and the frame support member 12 remain integrated and do not separate.

The frame support member 12 has a horizontal frame support wall portion 12B that abuts against the edge frame 1, and a lower bent piece portion 12C that is bent downwardly from the frame support wall portion 12B, and the lower bent piece portion 12C has a rotating body support horizontal wall portion 12E that has an arc-shaped notch portion 12D, and at a position opposite the notch portion 12D, has a slit-shaped window portion 12G into which a part of the rotating body 13 is inserted; 13 has a large-diameter lower disk portion 13A and a small-diameter upper disk portion 13B, and an annular groove 13C is formed between the large-diameter lower disk portion 13A and the small-diameter upper disk portion 13B; the inner peripheral edge of the arc-shaped cutout portion 12D is engaged with the annular groove 13C to hold the manual rotating body 13 in the insertion holding space 20, so that the manual rotating body 13 is reliably held in the frame receiving member 12 in a stable position and smoothly rotatable. In other words, once the manual rotating body 13 is assembled, there is no risk of it suddenly coming off the frame receiving member 12.

In addition, since the frame receiving member 12 is formed by punching and bending a single sheet of metal, it can be easily manufactured without the need for welding or crimping, and has excellent strength. In addition, it can be made compact and simple.
Furthermore, since the frame receiving member 12 is made of synthetic resin, it is suitable for mass production and costs can be reduced.

The manual rotating body 13 has small uneven teeth 21 formed on its outer circumferential surface 13D to prevent fingers from slipping; a bolt rod 17 is protruded horizontally outward from the vertical plate portion 8 of the base metal fitting 11, the bolt rod 17 is passed through the mesh of the bird-proof net 2 and a nut 18 is screwed into it, and when the bird-proof net 2 is fixed in a fixed state with the bird-proof net 2 sandwiched between the vertical plate portion 8 and the nut 18, the bird-proof net 2 comes into contact with the small uneven teeth 21 on the outer circumferential surface 13D of the manual rotating body 13, thereby preventing the manual rotating body 13 from rotating unexpectedly when the assembly is complete. Moreover, when the bird-proof net 2 is fixed with the nut 18, the manual rotating body 13 is automatically prevented from rotating, which further improves workability on site.
