Description

The present invention relates to eaves gutter supports and eaves gutter support structures.

A known support for eaves gutters located under the eaves of a folded-plate roof is a J-shaped eaves gutter support that includes a support body that is attached to the eaves of the folded-plate roof and an eaves gutter receiving portion that extends from the support body and supports the eaves gutters (see Patent Document 1).

This eaves gutter support comprises a support body with a roughly U-shaped support recess that fits over the eaves tip of a folded-plate roof, and a bolt that threads into a bolt threading hole drilled in the upper piece of the support recess to tighten and secure the support body to the eaves tip. It also comprises a vertical piece extending downward from the support body, and a U-shaped receiving portion with a horizontal piece and locking piece attached via an adjustment bolt so that they extend from the lower part of the vertical piece. Because the vertical piece, horizontal piece, and support piece are assembled in a U shape, they can support the eaves gutter.

Japanese Patent Application Laid-Open No. 2000-145062

The eaves gutter support described in Patent Document 1 is configured to support the eaves gutter with a U-shaped receiving portion consisting of vertical pieces, horizontal pieces, and locking pieces extending downward from the support body. Therefore, the eaves tip must be inserted into the support recess, the bolts tightened to fasten the support body to the eaves tip, and then the eaves gutter must be inserted into the receiving portion while adjusting the vertical positions of the horizontal pieces and locking pieces with the adjustment bolt. These operations require the support body to be temporarily fastened by tightening the bolts and nuts while holding the support body with one hand.
However, installing eaves gutter supports requires high-altitude work using scaffolding, which is not an easy task, and so it is desirable to design eaves gutter supports that minimize the burden on workers. Particularly when the eaves gutter is large and heavy, it can be difficult to stably support the eaves gutter with the support body that is temporarily fastened by tightening the bolts. For example, if the tightening force when tightening the bolts is insufficient, the support body may come off the tip of the eaves edge, causing the eaves gutter to fall.

The present invention was made in consideration of the above-mentioned circumstances, and aims to provide an eaves gutter support and eaves gutter support structure that is easy to install even when working at high altitudes such as under the eaves, and that can stably support even heavy eaves gutters.

In order to solve the above problems, the present invention proposes the following aspects.
"1" The eaves gutter support of this form is an eaves gutter support that is attached to the tip of the eaves board of a roof and supports an eaves gutter, and has a support body with a lower piece and an upper piece that form a recess into which the tip of the eaves board can be inserted, a vertical piece extending downward from a part of the lower piece, a horizontal piece extending from the tip of the vertical piece on the same side as the support body, a vertical side engaging piece extending upward from the tip of the horizontal piece and removably supported on the horizontal piece, an attachment piece removably attached to the tip of the vertical side engaging piece, an extension piece formed on the tip side of the attachment piece and positioned above the upper piece so as to be attachable to the upper piece, a first attachment bolt that is removably attached to the support body and passes through the upper piece and the lower piece, and a second attachment bolt that is removably attached to the extension piece and passes through the extension piece, the upper piece and the lower piece.

With the above-mentioned eaves gutter support, the tip of the eaves board is inserted into the recess in the support body, and the first mounting bolt that passes through the upper piece of the support body and the tip and lower pieces of the eaves board temporarily secures the eaves gutter support to the tip of the eaves board in a stable state. In this state, by changing the position of the vertical side locking piece that extends above the tip of the horizontal piece and opening up space on either side of the horizontal piece, the eaves gutter can be installed along the horizontal and vertical pieces, and the eaves gutter can be temporarily supported.
Furthermore, the work of inserting the tip of the eaves board into the recess in the support body and the work of tightening the first mounting bolt can be performed safely and easily by a single worker.
When the gutter support is temporarily fastened with the first mounting bolt, the gutter support can stably support even a heavy object, so even if a heavy object such as a gutter is placed on the horizontal piece, the gutter will not become unstable. This allows workers to install the gutter safely and with peace of mind, even in poor working conditions such as high places.

After the gutter is temporarily installed, the vertical side locking piece is positioned so that it extends upward from the tip of the horizontal piece, allowing the extension piece at the tip of the mounting piece to be attached to the upper piece of the support body. From this state, the extension piece, upper piece, eaves end board tip, and lower piece are fastened together with a second mounting bolt that passes through the lower piece to complete the installation of the eaves gutter support.
With the above-described configuration, the eaves gutter support can be stably supported by the first mounting bolt and the second mounting bolt, and even heavy eaves gutters can be stably supported by the eaves gutter support, and the installation work of the eaves gutter support can be carried out safely and easily.

"2" In the eaves gutter support of this embodiment, the vertical side engaging piece can be detachably and rotatably attached to the tip of the horizontal piece.

After installing the eaves gutter on the horizontal piece, it is preferable to attach the vertical locking piece to the horizontal piece, rotate the vertical locking piece while avoiding interference with the eaves gutter, and attach the extension piece to the upper piece of the support body. This operation makes it possible to install the second mounting bolt.

"3" In the eaves gutter support of this embodiment, the first mounting bolt and the second mounting bolt can be configured as fixing members that penetrate the tip of the eaves board inserted into the recess and secure the support body to the tip of the eaves board.

By using the first mounting bolt to penetrate and fix the tip of the eaves board, and the second mounting bolt to penetrate and fix the tip of the eaves board, the support body can be firmly fixed to the tip of the eaves board, allowing even heavy eaves gutters to be stably supported by the eaves gutter support.

"4" In the eaves gutter support of this embodiment, it is preferable that an inclined piece be formed at the end of the upper piece located on the entrance side of the recess, widening the gap between the openings on the entrance side of the recess.

The recess into which the tip of the eaves board is inserted has an inclined piece located at the upper end of the entrance side of the recess, which gradually widens the width of the entrance side of the recess outward. This makes it easy and reliable to insert the tip of the eaves board into the recess from the entrance side.

"5" The eaves gutter support of this embodiment can be configured with a pivotal connection portion provided at the connection between the horizontal piece and the vertical side engaging piece or at the midpoint of the horizontal piece, which pivotally supports the vertical side engaging piece or the tip end of the vertical side engaging piece and the horizontal piece along a plane including the support body, the vertical piece, and the horizontal piece.

When supporting an eaves gutter, rotating the vertical locking piece or the tip of the vertical locking piece and the horizontal piece downward via the pivot connection part separates the extension piece from the support body, widening the gap between the support body and the extension piece. Using this open space, the eaves gutter can be placed on the horizontal piece, temporarily supported by the horizontal piece. Then, rotating the vertical locking piece or the tip of the vertical locking piece and the horizontal piece upward allows the eaves gutter support to surround the eaves gutter, thereby supporting it.
When the vertical side retaining pieces or the tips of the vertical side retaining pieces and the horizontal piece are rotated upward, the rotation direction is along the plane including the vertical and horizontal pieces, not along the side of the eaves gutter. Therefore, there is no risk of the vertical side retaining pieces rubbing against the side of the eaves gutter, and there is no risk of damaging the eaves gutter during the work of supporting the eaves gutter.

"6" The eaves gutter support structure of this form is configured so that the eaves gutter is supported by an eaves gutter support attached to the tip of the eaves board of the roof, and the eaves gutter support comprises a support body having a lower piece and an upper piece that form a recess into which the tip of the eaves board can be inserted, a vertical piece extending downward from a part of the lower piece, a horizontal piece extending from the tip of the vertical piece on the same side as the support body, a vertical side engaging piece extending upward from the tip of the horizontal piece and detachably supported on the horizontal piece, and an attachment piece detachably attached to the tip of the vertical side engaging piece. and an extension piece formed at the tip of the mounting piece, positioned above the upper piece and attachable to the upper piece. The tip of the eaves board is inserted into the recess, and the support body is fixed to the tip of the eaves board by a first mounting bolt that passes through the upper piece, the tip of the eaves board, and the lower piece of the support body, and a second mounting bolt that passes through the extension piece, the upper piece, the tip of the eaves board, and the lower piece. The eaves gutter is supported in the area surrounded by the vertical piece, the horizontal piece, and the vertical side engaging piece.

With this type of eaves gutter support structure, the tip of the eaves board is inserted into the recess of the support body, and the eaves gutter support can be temporarily fixed to the tip of the eaves board in a stable state using a first mounting bolt that passes through the upper piece of the support body, the tip of the eaves board, and the lower piece.
In this state, by changing the position of the vertical side engaging piece extending above the tip of the horizontal piece to open up a space on either side of the horizontal piece, it becomes possible to install the eaves gutter along the horizontal piece and the vertical piece, thereby providing temporary support for the eaves gutter.
After the eaves gutter is temporarily installed, the vertical side engaging piece is positioned so that it extends upward from the tip of the horizontal piece, so that the extension piece at the tip of the mounting piece can be attached to the upper piece of the support body.
From this state, the extension piece, upper piece, tip of the eaves board, and lower piece are fastened together with a second mounting bolt that passes through them, completing the installation of the eaves gutter support.
As a result of the above, the eaves gutter support can be stably supported by the first mounting bolt and the second mounting bolt, and even heavy eaves gutters can be stably supported by the eaves gutter support, and a structure can be provided in which the eaves gutter support can be installed safely and easily.

"7" In this form of eaves gutter support structure, a configuration can be adopted in which the vertical side engaging piece is detachably and rotatably attached to the tip of the horizontal piece.

After installing the eaves gutter on the horizontal piece, it is preferable to attach the vertical side locking piece to the horizontal piece, rotate the vertical side locking piece while avoiding interference with the eaves gutter, and attach the extension piece to the upper piece of the support body. This operation makes it possible to install the second mounting bolt.

"8" In this form of eaves gutter support structure, a configuration can be adopted in which an inclined piece is formed at the end of the upper piece located on the entrance side of the recess, widening the spacing of the opening on the entrance side of the recess.

The recess into which the tip of the eaves board is inserted has an inclined piece located at the upper end of the entrance side of the recess, which gradually widens the width of the entrance side of the recess outward. This makes it easy and reliable to insert the tip of the eaves board into the recess from the entrance side.

"9" In this form of eaves gutter support structure, a configuration can be adopted in which a pivotal connection portion is provided at the connection portion between the horizontal piece and the vertical side engaging piece or at the midpoint of the horizontal piece, and which pivotally supports the vertical side engaging piece or the tip end of the vertical side engaging piece and the horizontal piece along a plane including the support body, the vertical piece, and the horizontal piece.

When supporting an eaves gutter, rotating the vertical locking piece or the tip of the vertical locking piece and the horizontal piece downward via the pivot connection part separates the extension piece from the support body, widening the gap between the support body and the extension piece. Using this open space, the eaves gutter can be placed on the horizontal piece, temporarily supported by the horizontal piece. Then, rotating the vertical locking piece or the tip of the vertical locking piece and the horizontal piece upward allows the eaves gutter support to surround the eaves gutter, thereby supporting it.
When the vertical side retaining pieces or the tips of the vertical side retaining pieces and the horizontal piece are rotated upward, the rotation direction is along the plane including the vertical and horizontal pieces, not along the side of the eaves gutter. Therefore, there is no risk of the vertical side retaining pieces rubbing against the side of the eaves gutter, and there is no risk of damaging the eaves gutter during the work of supporting the eaves gutter.

With the eaves gutter support of the present invention, the tip of the eaves end board is inserted into the recess in the support body, and the first mounting bolt that passes through the upper piece of the support body and the tip and lower pieces of the eaves end board temporarily fixes the eaves gutter support to the tip of the eaves end board in a stable state. In this state, by changing the position of the vertical side locking piece that extends above the tip of the horizontal piece and opening up a space on either side of the horizontal piece, the eaves gutter can be installed along the horizontal and vertical pieces, and the eaves gutter can be temporarily supported.
After the eaves gutter is installed, the extension piece at the tip of the mounting piece is placed on top of the upper piece of the support body, and then these are fastened together with a second mounting bolt that passes through the extension piece, upper piece, tip of the eaves board, and lower piece, completing the installation of the eaves gutter support.

Hereinafter, an example of an eaves gutter support and an eaves gutter support structure according to a first embodiment of the present invention will be described with reference to FIGS. 1 to 5. FIG.
The eaves gutter support of this embodiment is attached to the tip of the eaves end board of a folded plate roof, for example, and is used to support the eaves gutter.
As shown in Figures 1 and 2, a plurality of eaves gutter supports A of the first embodiment are attached at predetermined intervals along the eaves edge of a folded-plate roof B, and the eaves gutter 40 described below is supported by the plurality of eaves gutter supports A. The folded-plate roof B shown in this embodiment is made of a corrugated folded-plate roofing material 4 with a plurality of alternating peaks 2 and a plurality of valleys 3. In this embodiment, the peaks 2 and valleys 3 are both formed into corrugations with isosceles trapezoidal contours. Note that there are various types of folded-plate roofs B, such as a seam-jointed type, a folded-plate overlapping type, and a folded-plate interlocking type, and the eaves gutter support A of this embodiment can be applied to any type of folded-plate roof.

As shown in Figures 1 and 2, an eaves gutter support A is bolted to the tip end 2A of the eaves end plate that forms the peak portion of the mountain portion 2 of the folded-plate roof B.
The eaves gutter support A has a support body 10 with a lower piece 6, a rising piece 7, and an upper piece 9, which form a recess 5 at the top into which the eaves board tip 2A can be inserted. Also, below the support body 10, vertical pieces 16, horizontal pieces 17, vertical side locking pieces 18, and mounting pieces 22, which will be described later, are arranged so that together with the support body 10, they form a rectangular shape as a whole.

In this example, a rising piece 7 is formed on a portion of an end piece 8 overlapping one longitudinal end of the lower piece 6, rising at an angle from the lower piece 6, and an upper piece 9 is formed to extend this rising piece 7. The lower piece 6, rising piece 7, end piece 8, and upper piece 9 are all made of plate material of the same width. Also, in this example, a groove 6A is formed in the center of the upper surface in the width direction on the right end side of the lower piece 6, and flat plate portions 6B are formed on both sides of the groove 6A, i.e., on both widthwise sides of the lower piece 6. Furthermore, a protrusion 6D is formed on the back side of the portion of the lower piece 6 where the groove 6A is formed.
A gap of a certain width is formed between the lower piece 6 and the upper piece 9, and the tip 2A of the eaves end board of the folded-plate roof B is inserted into this corner until its tip reaches the rising piece 7. In other words, the tip 2A of the eaves end board is inserted into the recess 5.

In Figure 1, the gap between the lower piece 6 and the upper piece 9 has the rising piece 7 located at its left end as the farthest end, so the right end of the gap between the lower piece 6 and the upper piece 9 is referred to as the entrance side of the recess 5. A sloping piece 11 sloping away from the lower piece 6 is formed on the right end side of the upper piece 9 at the entrance side of the gap. The gap between the lower piece 6 and the upper piece 9, i.e., the opening on the entrance side of the recess 5, is widened in the area where this sloping piece 11 is formed. Therefore, when inserting the eaves end board tip 2A of the folded-plate roof B through this gap, the sloping piece 11 acts as a guide, making it easier to insert the eaves end board tip 2A.

The upper vertical piece 12 extends downward at an angle of approximately 90° from the right end of the lower piece 6 in Figure 1. A groove 12A is formed in the center of the upper vertical piece 12 in the width direction, and flat plate portions 12B are formed on both sides of the groove 12A, i.e., on both widthwise sides of the upper vertical piece 12. In addition, a protrusion 12D is formed on the back side of the groove 12A in the upper vertical piece 12. The overall width, groove width, and flat plate width of the upper vertical piece 12 are formed to be equal to those of the lower piece 6, respectively.

The lower vertical piece 13 is overlapped on the upper vertical piece 12, passing from the upper side thereof through the central and lower sides, and further extending downward from the upper vertical piece 12. The lower vertical piece 13 also has a groove 13A, a flat plate portion 13B, and a protrusion 13D. The lower vertical piece 13 has an overall width, groove width, and flat plate width that correspond to the overall width, groove width, and flat plate width of the upper vertical piece 12, so that the lower vertical piece 13 can be overlapped on the upper vertical piece 12.
The upper vertical piece 12 and the lower vertical piece 13 are integrated together by a bolt 14 passing through the overlapping portion of the two pieces and a nut 15 threaded onto the bolt 14 to form a vertical piece 16 .

A horizontal piece 17 is formed at the lower end of the lower vertical piece 13, extending horizontally at approximately 90° to the lower vertical piece 13. A groove 17A, a flat plate 17B, and a protrusion 17D are also formed on the horizontal piece 17. This horizontal piece 17 has an overall width, groove width, and flat plate width that correspond to the overall width, groove width, and flat plate width of the lower vertical piece 13.
A short bent piece 17E is formed at the tip of the horizontal piece 17 by bending the horizontal piece 17 outward at approximately 90 degrees. A vertical locking piece 18 is formed outside this bent piece 17E so as to intersect with the horizontal piece 17 at approximately 90 degrees. This vertical locking piece 18 has a flat portion 18C formed only at the portion that abuts the bent piece 17E, and similar to the horizontal piece 17, a groove portion 18A, a flat portion 18B, and a protrusion 18D formed along the entire length of the remaining portion. The length of the vertical locking piece 18, including the flat portion 18C, is slightly shorter than the length of the previous vertical piece 16. Therefore, taking into account the amount by which the flat portion 18C protrudes slightly downward from the horizontal piece 17, the tip (upper end) of the vertical locking piece 18 extends to a position close to one end of the lower piece 6.

A bolt 20 and a nut 21 threaded onto the bolt 20 are provided to pass through the portion where the flat portion 18C of the vertical locking piece 18 overlaps the bent piece 17E of the horizontal piece 17. This bolt fastening structure rotatably and detachably connects the flat portion 18C of the vertical locking piece 18 to the bent piece 17E of the horizontal piece 17. The vertical locking piece 18 is connected to the tip of the horizontal piece 17 so as to be rotatable around the bolt 20 as a rotation center axis. Note that the bolt 20 is disposed parallel to the length of the horizontal piece 17. In other words, the vertical locking piece 18 is supported rotatably around the bolt 20, which extends along the length of the horizontal piece 17, as a rotation center axis.
The portion where the flat portion 18C of the vertical locking piece 18 overlaps the bent piece 17E of the horizontal piece 17 is not limited to a bolt fastening structure using the bolt 20 and nut 21, but may instead be connected by a hinge, for example, between the bent piece 17E of the horizontal piece 17 and the flat portion 18C of the vertical locking piece 18. In this case as well, the vertical locking piece 18 is connected to the tip of the horizontal piece 17 so as to be rotatable around the hinge as the rotation center axis, and the vertical locking piece 18 is rotatably supported so as to rotate on the plane formed by the vertical locking piece 18 and the horizontal piece 17.

An approximately L-shaped mounting piece 22 is provided on the inside of the upper end of the vertical side engaging piece 18, with its lower side running along the inside of the upper end of the vertical side engaging piece 18 and its upper side running along the upper piece 9.
The mounting piece 22 has a groove 22A in the center in the width direction, flat plate portions 22B on both sides of the groove 22A in the width direction, and a protrusion 22D on the back side of the groove 22A. The lower side of the mounting piece 22 has the groove 22A, flat plate portion 22B, and protrusion 22D, just like the vertical side locking piece 18, and the overall width, groove width, and flat plate width are equivalent to the overall width, groove width, and flat plate width of the vertical side locking piece 18. Therefore, the lower side of the mounting piece 22 is overlapped and aligned along the inside of the upper end of the vertical side locking piece 18.
A bolt 25 and a nut 26 that screws onto the bolt 25 are provided so as to pass through the portion where the lower side of the mounting piece 22 overlaps with the inside of the upper end of the vertical side locking piece 18 .

The upper side of the mounting piece 22 is attached to the upper side of the upper piece 9 as an extension piece 22F. A flat plate portion 22G is formed at the tip of the upper side of the mounting piece 22, and this flat plate portion 22G is overlapped with the longitudinal center of the upper piece 9.

Through holes are formed through the lower piece 6 and the upper piece 9 where the lower piece 6 and the upper piece 9 are overlapped with a gap between them, and a first mounting bolt 31 is attached as a fixing member and inserted through these holes. A nut 33 is threaded onto the first mounting bolt 31. Furthermore, through holes are also formed through the flat plate portion 22G on the upper side of the mounting piece 22 where it overlaps the upper piece 9, penetrating the flat plate portion 22G, upper piece 9, and lower piece 6, and a second mounting bolt 32 is attached as a fixing member and inserted through these holes. A nut 34 is threaded onto the second mounting bolt 32.

1, when the tip 2A of the eaves end board is inserted into the recess 5, a through hole is also formed in the tip 2A of the eaves end board so as to align with the aforementioned through hole. Therefore, the first mounting bolt 31 is provided to pass through the lower piece 6, the upper piece 9, and the tip 2A of the eaves end board inserted between them, and by tightening the nut 33 threaded onto the first mounting bolt 31, the eaves gutter support A is fixed to the tip 2A of the eaves end board.
In addition, the second mounting bolt 32 is arranged to pass through the flat plate portion 22G, the lower piece 6, the upper piece 9, and the eaves end board tip portion 2A inserted between them, and the eaves gutter support A is fixed to the eaves end board tip portion 2A by tightening the nut 34 threaded onto the second mounting bolt 32.

The state shown in FIG. 1 shows a state in which an eaves gutter support A is attached to the tip end portion 2A of an eaves end board of a folded plate roof B.
The eaves gutter 40 is supported inside a rectangular frame surrounded by the vertical pieces 16, horizontal pieces 17, and vertical side locking pieces 18 of the eaves gutter support A. The eaves gutter 40 is composed of a bottom plate 40A, an inner plate 40B, and an outer plate 40C. As shown in Figure 1, in this embodiment, the height of the outer plate 40C of the eaves gutter 40 is slightly higher than the height of the inner plate 40B.

In addition, on the inside of the lower vertical piece 13 of the eaves gutter support A, a locking piece 42 consisting of a cut-and-raised piece that contacts the upper part of the inner panel 40B is formed, and on the inside of the vertical side locking piece 18, a locking piece 43 consisting of a cut-and-raised piece that contacts the upper end of the outer panel 40C is formed.

The process of attaching the eaves gutter support A to the folded-plate roof B having the configuration shown in FIG. 2 and supporting the eaves gutter 40 by the eaves gutter support A will be described below with reference to FIGS. 5 and 6.
In step 1, first, as shown in Figure 5(a), the vertical locking piece 18 is rotated downward around the bolt 20 so that the vertical locking piece 18 and the mounting piece 22 face downward. In this initial state, the storage space defined by the horizontal piece 17 and the vertical piece 16 is not closed by the vertical locking piece 18 and the mounting piece 22, but is open.
Next, as shown in Figure 5(b), the tip 2A of the eaves end board of the folded-plate roof B is slid into the recess 5 of the eaves gutter support A. In this state, the through-hole formed in the tip 2A of the eaves end board can be aligned with the through-holes formed in the lower piece 6 and the upper piece 9, so the first mounting bolt 31 is inserted through these through-holes as shown in Figure 5(c), and the nut 33 is screwed onto the first mounting bolt 31 and tightened.

As shown in Figure 5(c), the eaves gutter support A can be placed in a temporary support state by tightening the first mounting bolt 31 and nut 33. In this temporary support state, the eaves gutter support A can be stably supported on the folded-plate roof B, so the eaves gutter 40 can be safely and stably installed on the horizontal piece 17 as shown in Figure 5(c). Therefore, even if the work site is a high-altitude work site and the eaves gutter 40 is heavy, a single worker can safely and easily install the eaves gutter 40 temporarily.

Next, the vertical locking piece 18 is rotated upward so that the vertical locking piece 18 and the mounting piece 22 face upward as shown in Figure 6(d), and the extension piece 22F at the tip of the mounting piece 22 is placed on the upper piece 9. If the mounting piece 22 interferes with the eaves gutter 40 when rotating the vertical locking piece 18 upward, it is advisable to orient the vertical locking piece 18 upward while removing the bolt 20 and nut 21. With the vertical locking piece 18 facing upward, it can be reattached to the horizontal piece 17 by fastening it again with the bolt 20 and nut 21.
Furthermore, if the vertical side locking piece 18 and the mounting piece 22 can be twisted by connecting the bolt 20 and the nut 21 and the bolt 25 and the nut 26 in a loosened state, the vertical side locking piece 18 and the mounting piece 22 can be twisted in a direction that does not interfere with the eaves gutter 40 or the corrugated roof, and the mounting piece 22 and the vertical side locking piece 18 can be rotated while still connected to the horizontal piece 17 to rotate the vertical side locking piece 18 upward so that the vertical side locking piece 18 and the mounting piece 22 face upward as shown in Figure 6 (d), and the extension piece 22F at the tip of the mounting piece 22 can be installed on top of the upper piece 9.
Alternatively, the mounting piece 22 connected to the vertical side locking piece 18 can be removed from the vertical side locking piece 18 by removing the bolt 25 and nut 26, and only the vertical side locking piece 18 can be rotated upward to the state shown in Figure 6 (d), and then the mounting piece 22 can be reconnected to the vertical side locking piece 18 using the bolt 25 and nut 26.

When the mounting piece 22 is placed on the upper piece 9, the through holes formed in the mounting piece 22, upper piece 9, eaves board tip 2A, and lower piece 6 are aligned, so that the second mounting bolt 32 is passed through these, a nut 34 is screwed onto the second mounting bolt 32, and the second mounting bolt 32 and nut 34 are tightened together to complete the support structure for the eaves gutter 40 using the eaves gutter support device A as shown in Figure 6 (e).
If the eaves gutter support A is supported by the first mounting bolt 31 and the second mounting bolt 32 as shown in Figure 6 (e), the eaves gutter 40 can be stably supported by the eaves gutter support A attached to the folded plate roof B in an extremely stable state.

With the eaves gutter support A configured as described above, the tip 2A of the eaves end board can be inserted into the recess 5 of the support body 10, and the eaves gutter support A can be temporarily fixed to the tip of the eaves end board with the first mounting bolt 31 that passes through the upper piece 9 of the support body 10, the tip 2A of the eaves end board, and the lower piece 6. If the vertical side locking piece 18 is rotated downward in this state, the eaves gutter 40 can be installed along the horizontal piece 17 and the vertical piece 16, and temporarily supported.
Furthermore, the work of inserting the eaves board tip portion 2A into the recess 5 of the bracket body 10 and the work of tightening the first mounting bolt 31 can be performed safely and easily by a single worker.
When the eaves gutter support A is temporarily fixed with the first mounting bolts 31, the eaves gutter support A is in a state where it can stably support even a heavy object, so even if the eaves gutter 40, which is a heavy object, is placed on the horizontal piece 17, the eaves gutter 40 will not become unstable. Therefore, the worker can temporarily install the eaves gutter 40 safely and securely even in a place with a poor working environment, such as a high place.

After the eaves gutter 40 is temporarily installed, the vertical side engaging piece 18 can be rotated upward, and the extension piece 22F at the tip of the mounting piece 22 can be attached to the upper piece 9 of the support body 10. From this state, the extension piece 22F, the upper piece 9, the eaves end board tip portion 2A, and the lower piece 6 can be fastened together with the second mounting bolt 32 that penetrates them, completing the installation of the eaves gutter support.
With the above-described configuration, the eaves gutter support A can be stably supported by the first mounting bolt 31 and the second mounting bolt 32, and even a heavy eaves gutter 40 can be stably supported, and the installation work can be carried out safely and easily.

In the eaves gutter support A having the above-described configuration, a portion of the lower piece 6, the upper vertical piece 12, the lower vertical piece 13, the horizontal piece 17, and the vertical side engaging piece 18 all have grooves and ridges, making them resistant to twisting. Therefore, it is possible to provide an eaves gutter support A that can stably support the eaves gutter 40, even if the eaves gutter 40 is heavy and is prone to swaying or twisting due to wind, earthquakes, etc.
Furthermore, when supporting the eaves gutter 40, if the eaves gutter support A is fixed to the eaves end board tip 2A using the first mounting bolt 31 and the second mounting bolt 32, torsional force tends to concentrate on the upper side of the vertical piece 16 and the upper side of the vertical side engaging piece 18. In this regard, the upper side of the vertical piece 16 has a two-layer structure consisting of the upper vertical piece 12 and the lower vertical piece 13 with grooves and ridges fitted together, making it highly resistant to torsion. Furthermore, the upper side of the vertical side engaging piece 18 also has a two-layer structure consisting of the vertical side engaging piece 18 with grooves and ridges fitted together and the mounting piece 22, making it highly resistant to torsion. Therefore, the eaves gutter support A is resistant to torsion and has the characteristic of being able to stably support the eaves gutter 40.

The connection between the upper piece 9 and the mounting piece 22 is not limited to a bolt-fastening structure using the first mounting bolt 31 and nut 33, and for example, the tip of the upper piece 9 and the tip of the mounting piece 22 may be connected by a hinge. In this case, the mounting piece 22 is connected to the tip of the upper piece 9 so as to be rotatable around the hinge as the rotation center axis, and the mounting piece 22 is rotatably supported so as to be rotatable on the plane formed by the upper piece 9 and the mounting piece 22.
Furthermore, the connection between the bent piece 17E of the horizontal piece 17 and the flat portion 18C of the vertical side locking piece 18 may also be made by a hinge, in which case the vertical side locking piece 18 and the mounting piece 22 are each made freely rotatable by the hinge, and the vertical side locking piece 18 and the mounting piece 22 are connected by a bolt 25 that passes through the overlapping part of the upper part of the vertical side locking piece 18 and the lower part of the mounting piece 22 and a nut 26 that screws onto this.

Figure 7 is a simplified diagram to explain the possibility that when the eaves gutter 40 is supported by the eaves gutter support device A of the first embodiment, if the vertical side locking piece 18 is rotated around the bolt 20 as a fulcrum from the temporary support state shown in Figure 5 (c), the vertical side locking piece 18 may interfere with the eaves gutter 40 or another eaves gutter support device A.
As shown in Figure 7, the eaves gutter 40 is supported by a plurality of eaves gutter supports A installed at predetermined intervals along its length. If the bolts 20 are loosened and the vertical side engaging pieces 18 are rotated, there is a risk that the vertical side engaging pieces 18 will collide with or come into contact with the outer plate 40C of the eaves gutter 40, possibly damaging the surface of the outer plate 40C.
Furthermore, when multiple eaves gutter supports A are installed close to each other along the eaves gutter A, rotating the vertical side locking piece 18 may cause interference with the adjacent eaves gutter support A and damage the other eaves gutter supports A.
To solve these problems, it is preferable to use the eaves gutter support D of the second embodiment described below.

Second Embodiment
8(a) shows an eaves gutter support D of a second embodiment according to the present invention, which has the same basic structure as the eaves gutter support A of the first embodiment. That is, the eaves gutter support D has a support body 10, a lower piece 6, an upright piece 7, an upper piece 9, and a recess 5, and is equivalent to the structure of the first embodiment in that it has a lower vertical piece 13, an upper vertical piece 12, a vertical piece 16, and a vertical side locking piece 18 and an attachment piece 22. In the structure of the second embodiment, components equivalent to those of the first embodiment are designated by the same reference numerals, and detailed description thereof will be omitted.
In the structure of the second embodiment, the eaves gutter 50 is equipped with a bottom plate 50A, an inner plate 50B, and an outer plate 50C, which is the same as the structure of the first embodiment, but the inner plate 50B and the outer plate 50C are inclined slightly outward, and the cross-sectional shape of the eaves gutter 50 is different from that of the first embodiment. Therefore, the eaves gutter support D has an overall side shape as shown in Figure 8(a), and while the eaves gutter support A shown in Figure 1 has a side shape that is close to a rectangle, the eaves gutter support D has a side shape that resembles a pentagon.

In the structure of the second embodiment, the upper extension 22F of the mounting piece 22 is slightly longer than in the first embodiment and is connected to the upper piece 9. The lower side of the mounting piece 22 is aligned with the outside of the vertical side locking piece 18 and connected by a bolt 25 and nut 26. The position where the bolt 25 passes through the mounting piece 22 and the vertical side locking piece 18 to join them is approximately halfway up the height of the vertical side locking piece 18. This joining position is also near the center of the height of the outer panel 50C of the eaves gutter 50. Because the outer panel 50C of the eaves gutter 50 is tilted slightly outward, there is sufficient space between the vertical side locking piece 18 and the outer panel 50C at the above-mentioned joining position to accommodate the bolt 25. The locking piece 43 that was provided on the vertical side locking piece 18 in the configuration of the first embodiment has been omitted.

Furthermore, the upper vertical piece 12 extends further downward than in the structure of the first embodiment, reaching the lower side of the lower vertical piece 13, and is joined to the lower side of the lower vertical piece 13 by a bolt 14 and a nut 15. Because the inner plate 50B of the eaves gutter 50 is slightly inclined outward, there is a sufficient gap between the lower vertical piece 13 and the inner plate 50B at the above-mentioned joining position to accommodate the bolt 14. The bolt 14 penetrates the upper vertical piece 12 and the lower vertical piece 13, with its tip facing toward the eaves gutter 50 and its head facing outward from the upper vertical piece 12.
In the structures of the first and second embodiments, the position where the upper vertical piece 12 and the lower vertical piece 13 are joined, the position where the vertical side locking piece 18 and the mounting piece 22 are joined, and the length of each piece are not particularly important. It is preferable to adjust the length and joining position of each piece appropriately to match the shape of the eaves gutter to be used, and to join each piece at an appropriate position that matches the length of each piece and the shape of the eaves gutter to be used.

The difference between the configuration of the second embodiment of the eaves gutter support D and that of the first embodiment is the structure of the joint between the horizontal piece 17 and the vertical side engaging piece 18, which has a pivotal connection portion 51 at the connection portion between the tip of the horizontal piece 17 and the lower end of the vertical side engaging piece 18.
As shown in Figure 8(b), a cylindrical curled portion 18F, approximately one-third the width, is formed in the center of the lower end of the vertical locking piece 18, and cylindrical curled portions 17F, approximately one-third the width, are formed on both sides of the end of the horizontal piece 17 near the vertical locking piece 18. The end of the horizontal piece 17 and the lower end of the vertical locking piece 18 are rotatably connected by arranging the inner holes of these curled portions 17F, 17F and curled portion 18F coaxially and providing a connecting member 56 that passes through these inner holes. The curled portions 17F, 17F, 18F and the connecting member 56 form a pivotable connection portion 51.
The extending direction of the connecting member 56 is parallel to the width direction of the horizontal piece 17 or the width direction of the vertical locking piece 18. Therefore, when the eaves gutter 50 is supported as shown in Figure 8(a), the vertical locking piece 18 is connected to the horizontal piece 17 so as to be rotatable up and down along the plane of the paper in Figure 8, with the connecting member 56 as the pivot point. In other words, the vertical locking piece 18 is provided so as to be rotatable up and down along the plane including the upper vertical piece 12, the lower vertical piece 13, and the horizontal piece 17.
The vertical side locking piece 18 is rotatably connected to the horizontal piece 17 so that the extension piece 22F can be moved closer to or farther away from the upper piece 9 by rotating up and down around the connecting member 56 as a rotation fulcrum.

When the vertical locking piece 18 is rotated downward so as to move the extension piece 22F away from the upper piece 9, a large gap is created between the extension piece 22F and the upper piece 9. This state is the same as the position of the vertical locking piece 18 in the temporary support state shown in Figure 5(c) in the first embodiment.
Therefore, by utilizing the gap between the extension piece 22F and the upper piece 9, the eaves gutter 50 can be introduced inside the eaves gutter support D in the same manner as shown in Figure 5(c). After this, by rotating the vertical side locking piece 18 upward using the connecting member 56 as a fulcrum, the extension piece 22F can be positioned above the upper piece 9 as shown in Figure 8, and the periphery of the eaves gutter 50 can be surrounded by the eaves gutter support D.
In the first embodiment, the vertical locking piece 18 is configured to rotate from the state shown in Figure 5(c) around the bolt 20 as a rotation fulcrum, whereas in the second embodiment, the vertical locking piece 18 is rotated around the connecting member 56, which is oriented 90° differently from the bolt 20 as a rotation fulcrum. This allows the vertical locking piece 18 to be rotated without coming into contact with the eaves gutter 50. Therefore, according to the second embodiment, the vertical locking piece 18 can be rotated without damaging the eaves gutter 50, and the eaves gutter 50 can be supported by the eaves gutter support D.

In addition, in the state shown in Figure 7, the plane along which the vertical side locking piece 18 rotates is parallel to the plane of the paper in Figure 7, but in the configuration of the second embodiment, the plane along which the vertical side locking piece 18 rotates is perpendicular to the plane of the paper in Figure 7. Therefore, when the vertical side locking piece 18 is rotated, it does not come into contact with other adjacent eaves gutter supports D. Therefore, when the eaves gutter 50 is supported by multiple adjacent eaves gutter supports D, the other adjacent eaves gutter supports D will not be damaged.

"Third embodiment"
Figure 9 shows the third embodiment of the eaves gutter support E according to the present invention, and the basic structure of this eaves gutter support E is the same as that of the eaves gutter support A of the first embodiment or the eaves gutter support D of the second embodiment.
The difference between the construction of the eaves gutter support E of the third embodiment and that of the first and second embodiments is the structure of the joint between the horizontal piece 17 and the vertical side engaging piece 18.
In the second embodiment described above, the curled portions 17F, 17F, and 18F are provided at the above-mentioned joint portions, and the vertical locking piece 18 and the horizontal piece 17 are rotatably connected by the connecting member 56.
In the third embodiment, a bent piece 17G and an insertion piece 18G are provided at the joint portion, so that the vertical side locking piece 18 is rotatably connected to the horizontal piece 17.

The tip of horizontal piece 17 is bent upward at a substantially right angle relative to horizontal piece 17 to form an upward bent piece 17G, and an insertion hole 17H having a ladle-shaped outline in plan view is formed near the bent portion at the tip of horizontal piece 17. One end of this insertion hole 17H on the head side reaches the base end of bent piece 17G. In addition, an insertion piece 18G is formed protruding from the center of the lower end of vertical side locking piece 18, spanning approximately half the width of vertical side locking piece 18. Insertion piece 18G protrudes at a substantially right angle relative to vertical side locking piece 18.
A rectangular reinforcing plate 54 is fixed onto the horizontal piece 17 so as to be positioned over the end of the insertion hole 17H formed at the tip of the horizontal piece 17, and the tip side of the insertion piece 18G is inserted horizontally from the outside of the bent piece 17G into the insertion hole 17H of the bent piece 17G and below the reinforcing plate 54, thereby rotatably connecting the vertical side locking piece 18 to the horizontal piece 17. The insertion piece 18G of the vertical side locking piece 18 and the bent piece 17G having the insertion hole 17H form a pivotal connection part 52.

In the eaves gutter support E of the third embodiment, the horizontal piece 17 supports the eaves gutter when the insertion piece 18G is inserted into the insertion hole 17H on the base end side of the bent piece 17G as shown in Figures 9 and 10.
In this case, the insertion piece 18G supports the horizontal piece 17 via the reinforcing plate 54, so that the eaves gutter can be received by the horizontal piece 17.
Furthermore, since the vertical side locking piece 18 is connected to the horizontal piece 17 so that it can be rotated up and down using the insertion portion of the insertion piece 18G as a fulcrum, interference with the eaves gutter can be avoided when the vertical side locking piece 18 is rotated up and down, as with the structure of the second embodiment described above. Therefore, the eaves gutter will not be damaged when working to support the eaves gutter using the eaves gutter support E. Furthermore, even when multiple eaves gutter supports E are arranged adjacent to each other to support the eaves gutter, as in the case shown in Figure 7, interference with other adjacent eaves gutter supports E can be avoided, so there is no risk of damaging other eaves gutter supports E during work to support the eaves gutter.

Fourth Embodiment
Figure 11 shows the eaves gutter support G of the fourth embodiment of the present invention, and the basic structure of this eaves gutter support G is the same as that of the eaves gutter support A of the first embodiment or the eaves gutter support D of the second embodiment.
The difference between the construction of the eaves gutter support G of the fourth embodiment and that of the first and second embodiments is the structure of the joint between the horizontal piece 17 and the vertical side engaging piece 18 and the structure of the horizontal piece 17.
11, the lower end of the vertical locking piece 18 and the tip of the horizontal piece 17 are integrally connected at a substantially right angle. A pivotal connection 60 is provided in the center (midway) of the horizontal piece 17 in the longitudinal direction.

As an example, the pivotal connection part 60 may have a similar configuration to the pivotal connection part 51 shown in Fig. 8(b). For example, the horizontal piece 17 may be divided into two horizontal piece halves 17J and 17K at the center in the longitudinal direction, two curled parts 61 may be formed at the divided part, and an axial connecting member may be inserted through the two curled parts to form the pivotal connection part 60. Alternatively, two curled parts may be formed at one end of each horizontal piece half 17J or 17K, and one curled part may be formed at the end of the other horizontal piece half 17J or 17K, with the other curled part sandwiched between the two curled parts, and these may be connected by an axial connecting member.
In the horizontal piece 17 of the fourth embodiment, the horizontal piece half 17K is integrated with the lower vertical piece 13, but the horizontal piece half 17J is connected to the horizontal piece half 17K so as to be freely rotatable up and down with the pivotal connection part 60 as a fulcrum.

Therefore, by rotating the horizontal piece half 17J, the vertical side locking piece 18, and the mounting piece 22 downward via the pivotal connection part 60, the eaves gutter support F can be placed in a temporary support state similar to the temporary support state of the first embodiment previously described with reference to Figure 5(c). In this temporary support state, a large gap is created between the horizontal piece half 17K and the upper piece 9, and this gap can be used to install the eaves gutter on the horizontal piece half 17K. After the eaves gutter is installed, the horizontal piece half 17J, the vertical side locking piece 18, and the mounting piece 22 are rotated upward via the pivotal connection part 60 to connect the mounting piece 22 to the upper piece 9, allowing the eaves gutter to be stored inside the eaves gutter support G.
In the eaves gutter support G, as in the eaves gutter supports D and E of the second and third embodiments, the vertical side locking piece 18 can be rotated up and down relative to the horizontal piece 17. Therefore, when the vertical side locking piece 18 is rotated up and down, interference with the eaves gutter 50 can be eliminated, and interference with other adjacent eaves gutter supports F can also be eliminated.
