Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gutter connector for connecting a rainwater gutter mounted on a roof of a house or the like.

[0002]

2. Description of the Related Art Generally, a gutter for collecting rainwater in a proper place and treating the rainwater is attached to the roof of a house over the entire circumference. This gutter is usually formed by pressing galvanized iron or the like into a semicircular cross section, roll-forming the opposite edges thereof into a circular cross section, and cutting this into a predetermined length. For this reason, when it is actually installed in a house or the like, it is necessary to connect a plurality of gutters of a predetermined length.

In the connection work in this case, first, one gutter is attached to a fixing metal member fixed to a wall surface of a house. After that, the roll part at one end of another gutter is expanded, and the expanded roll part is inserted into the fixed roll part of the gutter and set, and then the overlapping parts of both roll parts are caulked. By
It is to connect multiple gutters.

Here, in the case of crimping the overlapping portion of the roll portion of the gutter to be connected, conventionally, a connecting tool 30 as shown in FIG. 6 is used.
Was used. That is, the connector 30 is generally used when bending a sheet metal such as a galvanized iron roof plate, and has a pair of bar-shaped portions 31 and 32 at one end that serve as handles,
At the other end, a pair of rod-shaped bodies 35, 36 having a pair of loose arc-shaped caulking portions 33, 34 continuous with the rod-shaped portions 31, 32 are connected by a pin 37 serving as a fulcrum. ing. The crimp portions 33, 34 and the rod-shaped portions 31, 3
2 is formed so as to extend in a substantially straight line across the pin 37, and the crimp portions 33 and 34 extend considerably longer than the pin 37, and the tips of the crimp portions 33 and 34 are the same as those described above. It is formed in a flat shape so that it can be used for various operations.

[0005]

However, according to the above structure, the caulking portions 33, 34 and the rod-shaped portion 31,
Since 32 is formed in a substantially straight line shape with the pin 37 sandwiched between them, when connecting the gutter, when the swaged part of the roll part of the gutter located on the wall side of the house is caulked, a connecting tool is used. It is necessary to lie down for a while and apply the crimped part to the overlapping part of the roll part. For this reason, one end of the bar-shaped portion that serves as a handle hits the wall of the house, and thus it is necessary to place the gutter far away from the wall of the house, and there is a problem that the connection work becomes extremely complicated.

Further, since the caulking portions 33 and 34 are formed to be considerably long from the pin 37, it is difficult to align the roll portion with the overlapping portion, and the force acting on the caulking portion is generated due to the relation of the moment. There is also a problem that a strong connection cannot be made because it is weak.

Further, since the caulking portions 33 and 34 are formed flat, the roll portion is often crushed during the caulking work of the roll portion, which is preferable in terms of strength and appearance. There wasn't.

The present invention has been made in view of the above problems, and when connecting a gutter, the rod-shaped portion hits the wall surface or the eaves of the house, deteriorating the workability, and the positioning of the caulking portion is troublesome. It is an object of the present invention to provide a connector for exclusive use of gutter connection, which is excellent in workability and does not have insufficient crimping force of a crimping portion and is easy to use.

That is, the gutter connector 1 according to the first aspect of the invention is
A pair of rod-shaped bodies 6 and 7 having a pair of rod-shaped portions 2 and 3 as a handle at one end and a pair of crimped portions 4 and 5 continuous to the rod-shaped portions 2 and 3 at the other end are fulcrum points. Which are connected to each other by a pin 8 that is substantially parallel to the extending direction of the caulking portions 4 and 5 and the extending directions of the rod-shaped portions 2 and 3 or less. When formed to intersect at
Together, each caulking part 4 and 5 is formed near the pin 8
A recess 13 having a semicircular cross section is provided at a position where the parts 4 and 5 face each other.
14 is formed.

Further, in the gutter connector 1 according to a second aspect of the present invention, in the above, each of the caulking portions 4 and 5 has a flat rectangular parallelepiped shape.
At the same time, escape the rod-shaped body 7 to the caulking portion 4 on the side of the rod-shaped body 7.
The notch 15 is formed.

As described above, the gutter connector 1 according to the invention of claim 1 is formed so that the extending directions of the caulking portions 4, 5 and the rod-shaped portions 2, 3 intersect at substantially right angles or less. Therefore, when connecting the gutter 18 to the house 16
When crimping the overlapping portion B of the roll portions 19 and 23 of the gutter 18 located on the wall side of the It can be applied to B, and even if the bar-shaped parts 2 and 3 serving as handles are opened, one bar-shaped part 2 does not hit the wall of the house, and the caulking work can be performed smoothly. . Especially each caulking
Since the parts 4 and 5 are formed near the pin 8, the moment
Due to this, a large caulking force is applied to the caulking portions 4 and 5.
At the same time, the caulking portions 4 and 5 were formed with concave portions having a semicircular cross section.
Therefore, the roll portions 19 and 23 of the gutter 18 are superposed without being crushed.
You will be able to connect.

According to the gutter connector 1 of the invention of claim 2,
Each caulking portion 4 and 5 has a flat rectangular parallelepiped shape,
The top surface is flat, and there is no unnecessary portion above the pin 8.
Therefore, even when the gutter 18 is close to the roof tip 17, the caulking is performed.
The workability will not be impaired by the contact of the portion 5.
Further, the caulking portion 4 on the side of the rod-shaped body 7 does not allow the rod-shaped body 7 to escape.
Since the notch 15 is formed, it can be used for expanding the rod-shaped body 7.
There is no obstacle.

[0013]

Embodiments of the present invention will now be described in detail with reference to the drawings. As shown in the perspective view of FIG. 1, the gutter connector 1 of the present invention has a pair of rod-shaped portions 2 and 3 as a handle at one end, and a pair of rod-shaped portions 2 and 3 continuous with the rod-shaped portions 2 and 3 at the other end. Caulking section 4,
A pair of metal rod-shaped bodies 6 and 7 having 5 are connected by a pin 8 serving as a fulcrum. The caulking portions 4 and 5 and the rod-shaped portions 2 and 3 extend in a substantially right-angled direction with respect to the pin 8, that is, the extending direction of the rod-shaped portion 2 and the extending direction of the caulking portion 4, Further, the extending direction of the rod-shaped portion 3 and the extending direction of the caulking portion 5 are formed so as to intersect each other at a substantially right angle, and the caulking portions 4 and 5 are located in the vicinity of the pin 8. There is. Further, the caulking portions 4 and 5 have a flat rectangular parallelepiped shape, and recesses 13 and 14 having a semicircular cross section are formed between the pair of ribs 11 and 12 on the facing surfaces 9 and 10 that face each other. Has been done. Further, the caulking portion 4 is formed with a notch portion 15 which serves as a stopper and a relief when the rod-shaped body 7 is expanded.

When using the gutter connector 1 thus constructed, the rod-shaped portions 2 and 3 are expanded by hand and the caulking portions 4 and 5 are expanded to be caulked as shown in FIG. Recess 1 of parts 4, 5
After applying 3 and 14 to the crimped portion, the rod-shaped portions 2 and 3 are brought close to each other and crimped.

Specifically, it is used as shown in FIG.
That is, a gutter 18 for collecting and treating rainwater in a proper place is attached to the roof end 17 of the house 16 over the entire circumference. The gutter 18 is usually formed by pressing galvanized iron or the like into a semicircular cross section.
9 is roll-formed. Further, since the gutter 18 is formed to have a predetermined length, the gutter 18 having a predetermined length is actually used.
Will be connected multiple times.

Here, in connection work of the gutter 18, first, a fixing metal fitting 21 and a stopper 22 fixed to the wall surface 20 of the house 16.
To remove the gutter 18 that was fixed by
Expand 2 and pull the gutter 18 away from the house 16 a little. Then, the roll portion 19 at one end of the separated gutter 18 is expanded,
After inserting and setting in the roll portion 23 at one end of the gutter 18 on the other side to be connected, the gutter connector 1 is inserted from below (since there is the roof tip 17, it cannot be inserted from above.) Between the wall surface 20 and the gutter 18. The gutter 18 is connected by inserting and crimping the overlapping portions A and B of both roll portions 19 and 23 with the gutter connector 1.
The above is the case where the gutter 18 is close to the wall surface 20, and if there is a gap between the gutter 18 and the wall surface 20 into which the gutter connector 1 can be inserted from below, the gutter 18 does not necessarily have to be separated.

In this case, since the gutter connector 1 of the present invention is formed such that the extending directions of the caulking portions 4 and 5 and the rod-shaped portions 2 and 3 intersect at substantially right angles, the connector 1 is omitted. Standing vertically, in other words, the rod-shaped body 6 and the wall surface 20 of the house 16 are parallel to each other, and the crimping portions 4 and 5 thereof can be applied to the overlapping portions A and B of the roll portions 19 and 23, Even if the bar-shaped parts 2 and 3 which are the handles are opened, one bar-shaped part 2 is on the wall surface 20 of the house 16.
There is no such thing as hitting. Therefore, the roll portions 19 and 23 can be swaged without pulling the gutter 18 far away from the wall surface 20, so that the swaging work can be performed smoothly. In particular, since the upper surface of the caulking portion 5 is flat and there is no useless portion in the upper portion of the pin 8, even if the gutter 18 is close to the roof tip 17, it is possible that the gutter 18 impairs workability. There is no.

Further, since the caulking portions 4 and 5 are formed in the vicinity of the pin 8, the caulking portion 4 can be easily aligned with the overlapping portions A and B of the trough 18, and the caulking portion 4 is caused by the moment. 5,
Since the force that acts on is strong, a strong connection can be made.

Further, since the facing surfaces 9 and 10 of the caulking portions 4 and 5 are provided with the concave portions 13 and 14 having a shape corresponding to the roll portions 19 and 23 of the gutter 18, the overlapping portions A and B of the overlapping portions A and B are formed. The roll portions 19 and 23 are not crushed during the crimping work, and a crimped state with good strength and appearance can be obtained.

In the present embodiment, the rod-shaped portions 2 and 3 and the caulking portions 4 and 5 intersect with each other at a substantially right angle, but the present invention is not limited to this, and the rod-shaped body 2 is not limited thereto. Three
The same effect can be obtained even if the caulking portions 4 and 5 have a shape in which the extending direction forms an acute angle.

As described above, according to the invention of claim 1,
Since the extending direction of the caulking part and the rod-shaped part intersects each other at a right angle or less, when connecting the gutter, the stack of the gutter roll part located on the wall side of the house is overlapped. When crimping the part, it is possible to stand the gutter connector almost vertically and apply the crimped part to the overlapping part of the roll part,
Even if the bar-shaped part that serves as a handle is opened, one bar-shaped part does not hit the wall of the house. As a result, the caulking work can be performed without significantly separating the gutter from the wall of the house, and the connection workability of the gutter can be significantly improved . Especially, each caulking part is formed near the pin.
Since it is easy to align the gutter with the overlapping part,
However, due to the moment, the force acting on the caulking part becomes stronger.
Therefore, a strong connection can be made. Also, the caulking section
Since a concave section with a semicircular cross section was formed on the
There is no need to crush the roll part of the gutter at work,
A crimped state that is good in terms of strength and appearance can be obtained .

According to the invention of claim 2, each caulking
The shape of the part is flat and the upper surface of the caulking part is flat
Since there is no useless part above the pin, the gutter is the tip of the roof.
Even if it is close to the
There is no such thing. Also, the caulking part on the rod side
Since a notch that escapes the rod is formed in the
It can be expanded without any hindrance.
