Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connecting member for a rain gutter and a connecting structure of the connecting member for the rain gutter, which is prevented from directly falling under the eaves along the outer surface of the connecting member for the gutter.

[0002]

2. Description of the Related Art With the recent diversification and modernization of house designs, various shapes of rain gutters have been put into practical use in addition to those having a conventional substantially semicircular cross-sectional shape. I have. Among them, in particular, for the purpose of improving the design of the eaves of a house, a rain gutter having an irregular cross-sectional shape in which the outer surface of the gutter body is inclined rearward to give a sense of unity with the roof has been proposed. I have.

[0003]

In the case of a rain gutter having the above-mentioned irregular cross-sectional shape, rainwater falling on the gutter main body travels along the outer surface of the gutter main body, although the design is excellent. There has been a problem that the outer surface of the gutter main body is contaminated by rainwater transmitted down the eaves main body and rainwater transmitted on the outer side surface of the gutter main body, thereby deteriorating the appearance.

By the way, in order to solve this problem,
For example, Japanese Unexamined Patent Publication (Kokai) No. 3-217747 discloses a rain gutter having a groove-shaped or stepped water-stop surface formed on a front wall of a gutter main body, and a through-hole formed at a bottom portion of the water-stop surface. Rain gutters have been proposed in which rain water received on the water surface is introduced into a rain water passage formed in a gutter body. In the case of this rain gutter, since the cross-sectional shape of each wall of the gutter main body is formed in a linear shape, the deformation of the gutter main body is large, and the adhesion between the gutter main body and the connecting member is poor due to the bending of each wall. However, there is a problem that water leakage easily occurs. In addition, since the number and size of the formed through holes are restricted so that the strength of the rain gutter is not reduced by the through hole formed at the bottom of the water stop surface, the through hole is easily clogged, and the rain water received on the water stop surface is difficult. Stagnation or rainwater may overflow during heavy rain,
There is a bulge of the gutter main body below the water stop surface, and it is not possible to completely eliminate the possibility that the outer surface of the gutter main body is contaminated by rainwater transmitted on the outer side surface of the gutter main body. There was a problem of worsening. Furthermore, since the through hole is formed at the bottom of the water stop surface, there is a problem that the manufacturing cost of the rain gutter increases in relation to the manufacturing method of the rain gutter.

[0005] In order to address the above-mentioned problems of the conventional rain gutter, the applicant of the present invention has formed a structure in which the middle part of the front wall of the gutter body of the rain gutter projects outward, A projecting wall is formed extending in the longitudinal direction of the gutter body so that the wall extends obliquely upward, and rainwater is directed toward the end of the gutter body by the upper surface of the upper front wall of the gutter body and the inner surface of the projecting wall. A rain gutter is proposed in which a sub rainwater passage for guiding is formed, and the sub rainwater passage of the gutter main body is communicated with a main rain water passage formed in the gutter main body at a position of a connecting member arranged at an end of the gutter main body. (Japanese Patent Application No. 9-246)
199).

The rain gutter surely prevents rain water from directly falling under the eaves along the outer surface of the rain gutter by forming a sub rain water passage in the gutter main body, and also prevents rain water from catching in the sub rain water passage. Is introduced into the main rainwater passage formed in the gutter main body at the position of the connecting member arranged at the end of the gutter main body, thereby eliminating a through hole for introducing into the rainwater passage formed in the gutter main body, and having a cross-sectional shape. This makes it possible to reduce the manufacturing cost of rain gutters, thereby achieving a remarkable effect.

However, the connecting member provided at the end of the gutter main body does not take any measures to prevent rainwater from directly falling under the eaves along the outer surface of the connecting member. The rainwater that has fallen on the surface of the connecting member falls directly down the eaves along the outer surface of the connecting member, and the outer surface of the connecting member is contaminated by the rainwater transmitted on the outer surface of the connecting member. Was.

The present invention has been made in view of the above-mentioned problems of the connecting member of a gutter, and it is possible to reliably prevent rainwater from directly falling under the eaves along the outer surface of the connecting member of the gutter. It is an object of the present invention to provide a rain gutter connection member and a connection structure thereof, in which rainwater received by the connection member is introduced into a sub rainwater passage formed in the gutter main body so as to be drainable.

[0009]

In order to achieve the above object, a connecting member for a rain gutter according to the present invention is formed so that a middle portion of a front wall of a gutter main body projects outward, and a lower front portion of the front wall is formed. A projecting wall is formed extending in the longitudinal direction of the gutter body so that the wall extends obliquely upward, and rainwater is directed toward the end of the gutter body by the upper surface of the upper front wall of the gutter body and the inner surface of the projecting wall. In the connecting member for connecting the gutter main body forming the guiding sub-rainwater passage, while forming the middle of the front piece of the connecting member so as to protrude outward, the rainwater falling on the upper front piece of the front piece is removed. The gutter is introduced into a sub rainwater passage of the rain gutter.

[0010] The connecting member of the rain gutter is formed so that the middle of the front piece of the connecting member protrudes outward, and the rain water falling on the upper front piece of the front piece is supplied to the auxiliary rain water passage of the rain gutter. In this way, it is possible to reliably prevent rainwater from directly falling under the eaves along the outer surface of the connecting member of the gutter, and to descend on the upper and lower pieces of the front piece of the connecting member. The splashed rainwater can be introduced and drained into a sub rainwater passage formed in the gutter main body.

In order to introduce the rainwater falling on the upper front piece of the front piece into the auxiliary rainwater passage of the rain gutter, specifically, the longitudinal length of the connecting member is set such that the lower front piece of the front piece extends. A secondary rainwater that forms a projecting portion that is continuous in the direction and guides rainwater that has fallen on the upper and front pieces of the front piece toward the accessory rainwater passage of the gutter main body by the upper surface of the upper front piece of the connecting member and the inner surface of the projecting portion. A passage can be formed.

[0012] In order to introduce rainwater falling on the upper and lower pieces of the front piece into the auxiliary rainwater passage of the rain gutter, specifically,
By forming the upper front piece of the front piece so as to be inclined toward the end of the connecting member, it is possible to guide rainwater falling on the upper front piece of the front piece toward the auxiliary rainwater passage of the gutter main body. it can.

Further, in the rain gutter connection structure of the present invention using the rain gutter connection member, the gutter main body is provided such that the sub rainwater passage of the gutter main body is positioned at the position of the connection member disposed at the end of the gutter main body. The main rainwater passage is formed so as to communicate with it. In this case, the main rainwater passage formed in the gutter main body through a gap between the adjacent gutter main bodies formed by connecting the sub gutter main body of the gutter main body by a connecting member so that the adjacent gutter main bodies do not contact each other. Can be communicated with.

[0014] In this rain gutter connection structure, the rain water that has fallen on the upper and lower pieces of the front piece of the connection member is introduced into a sub rain water passage formed in the gutter body, and then drained into the main rain water passage formed in the gutter body. can do. Further, by connecting the main gutter body formed in the gutter body to the main rainwater passage through a gap between the adjacent gutter bodies, the connection structure of the gutter can be simplified.

[0015]

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a connecting member of a gutter according to the present invention;

FIGS. 1 to 5 show an example of a gutter connecting member of the present invention and a gutter to which the connecting structure is applied. The gutter main body (eave gutter) 1 of the rain gutter is used by being installed at the eaves of a house. As shown in FIG. 1, a front wall 11, a rear wall 12 facing the front wall 11, and a bottom It has a wall 13, has an upper side opened to introduce rainwater from the roof, and has a main rainwater passage 10 formed therein. The whole has a substantially pentagonal rectangular cross-sectional shape. And the front wall 11, the rear wall 12, and the bottom wall 13
Each of them has a linear shape with almost flat surfaces, and has the appearance of a square gutter. The front wall 11 is formed so that the middle thereof projects outward (forward), the upper front wall 11a of the upper half extends obliquely rearward and upward, and the lower half lower front wall 11b Is extended obliquely forward and upward, and has a projecting portion 14 that projects outward in the middle of the front wall 11. This gutter main body 1 can be formed by a method such as extrusion molding or pultrusion molding using a metal such as synthetic resin or aluminum. In this case, each of the walls 11, 1 is formed.
The thickness of each of the members 2 and 13 is set to about 1 to 2 mm depending on the material and the like so as to have a predetermined strength required as a rain gutter.

In this case, the lower front wall 11 of the front wall 11
b, a projecting wall 15 extending in the longitudinal direction of the gutter main body 1 is formed so as to extend obliquely upward, and the gutter is formed by the upper surface of the upper front wall 11 a of the gutter main body 1 and the inner surface of the protruding wall 15. A non-porous auxiliary rainwater passage 16 that guides rainwater toward the end of the main body 1
Is formed. With this configuration, the rainwater that has fallen on the upper surface of the upper front wall 11a is received by the auxiliary rainwater passage 16 along the upper surface. Then, even in a strong wind or the like, the rainwater that has fallen on the upper surface of the upper front wall 11a of the gutter main body 1 can be reliably received by the sub rainwater passage 16 and the rainwater can be guided toward the end of the gutter main body 1. As described above, the distal end 15a of the protruding wall 15 is bent obliquely rearward and upward so as to be substantially parallel to the upper surface of the upper front wall 11a of the gutter main body 1, and further,
An auxiliary rainwater passage 16 having its tip bent horizontally to open obliquely upward parallel to the upper surface of the upper front wall 11a.
Is formed.

Further, on the upper edges of the front wall 11 and the rear wall 12,
The strength of the gutter main body 1 is increased, the rigidity is improved to prevent meandering, and the ear portions 11c and 12a that are engaged with and held by the gutter hanging bracket and the connecting member 2 are formed.

As described above, the upper surface of the upper front wall 11a of the gutter main body 1 and the inner surface of the protruding wall 15 formed by extending the lower front wall 11b to extend obliquely upward, toward the end of the gutter main body 1. By forming the non-porous sub-rainwater passage 16 for guiding rainwater, the rainwater falling on the upper surface of the upper front wall 11a of the front wall 11 is received by the sub-rainwater passage 16 and the overhanging portion 14 of the front wall 11 is formed. This prevents rainwater from falling on the surface of the lower front wall 11b of the front wall 11, that is, the outer surface of the lower front wall 11b, and prevents rainwater from directly falling under the eaves along the surface of the front wall 11 of the gutter main body 1. It is possible to reliably prevent the occurrence, and to make the cross-sectional shape of the gutter main body 1 uniform.
The rainwater received in the sub rainwater passage 16 is drained to the main rainwater passage 10 of the gutter main body 1 at the position of the connection member 2 as described later.

The upper front wall 11a and the lower front wall 1 of the gutter main body 1 are also provided.
1b and the bottom wall 13, among which the bottom wall 13 is preferably formed to be curved outward with a predetermined radius of curvature R11a, R11b, R13, respectively. Then, the curvature radii R11a, R11b, R13 in the case of bending are:
It can be set arbitrarily according to the size of the gutter main body 1 and the like. If it is a square gutter, it is desirable to form it so as to have a radius of curvature of 150 to 500 mm. In this case, if the radius of curvature is larger than 500 mm, the degree of curvature is too small to reduce the deformation, and each wall is bent, particularly, bent inward, resulting in poor adhesion to the connection member 2. Becomes On the other hand, if the radius of curvature is smaller than 150 mm, the gutter main body 1 becomes too round, and the appearance as a square gutter cannot be maintained. Note that the rear wall 12 may be curved with a similar radius of curvature. With such a configuration, the strength of the gutter main body 1 and the adhesion to the connection member 2 can be further improved. Thereby, the deformation of the gutter main body 1 can be reduced, and further, each wall of the gutter main body 1 does not bend inward, and the adhesion between the outer surface of the gutter main body 1 and the inner surface of the connection member 2 is improved. Thus, water leakage can be prevented.

FIGS. 2 to 3 show a first embodiment of the connecting member 2 disposed at the end of the gutter main body 1 shown in FIG. The connecting member 2 is called a gutter joint used to connect the gutter bodies 1 to each other, and includes an upper front piece 21a and a lower front piece 21.
b and a rear piece 22 facing the front piece 21
And the bottom piece 23. Like the gutter main body 1, the upper part has an open side, and the whole has a substantially pentagonal rectangular cross-sectional shape so that the gutter main body 1 can be fitted closely inside. . The connecting member 2 can be molded by a method such as injection molding using a synthetic resin or the like. In this case, the thickness of each of the pieces 21, 22 and 23 has a predetermined strength required for the connecting member 2. Depending on the material, etc.
２2 mm.

In this case, in the middle of the front piece 21 where the upper front piece 21a and the lower front piece 21b are connected, the upper front piece 21b is connected obliquely rearward from the upper end of the lower front piece 21b substantially parallel to the upper front piece 21a. The projecting portion 24 also serving as a C-shaped engaging portion opened inward is formed by the connecting piece 24b thus formed and the cover piece 24c connected further obliquely downward. The upper surface of the upper front piece 21a of the connecting member 2 and the inner side surface of the protrusion 24 for introducing rainwater that has fallen on the upper front piece 21a of the front piece 21 into the sub rainwater passage 16 of the gutter main body 1. That is, the auxiliary rainwater passage 26 is formed by the upper surface of the cover piece 24c. Thus, the rainwater falling on the upper surface of the upper front piece 21a of the front piece 21 is received by the auxiliary rainwater passage 26 and guided toward the auxiliary rainwater passage 16 of the gutter main body 1, and the front piece 2
The first protrusion 24 prevents rainwater from falling on the surface of the lower front piece 21 b of the front piece 21, that is, the outer surface of the lower front piece 21 b, and the rainwater travels along the surface of the front piece 21 of the connecting member 2 and goes under the eaves. Direct dropping can be reliably prevented.

The upper edges of the front piece 21 and the rear piece 22
An engaging portion 21 for engaging with the ear portions 11c and 12a formed on the upper edge of the gutter main body 1 to firmly connect with the gutter main body 1.
c and 22a are respectively formed. The engaging portions 21c and 22a are formed with cutout portions 21d and 22b at substantially middle positions in the longitudinal direction, respectively, so that the engaging portions 21c and 22a can be deformed as necessary, and a connection operation described later can be performed. Make it easier to do.

On the inner surface of the rear piece 22, a stopper 2 for defining a gap between the adjacent gutter bodies 1, 1 connected to the connecting member 2 on both sides in the center in the longitudinal direction.
5, 25 are protruded. The stoppers 25, 25 can be provided on the front piece 21 or the bottom piece 23. However, from the viewpoint of the connection work between the flow of rainwater and the gutter main body 1, it is preferable that the stoppers 25, 25 be provided on the rear piece 22 as in the present embodiment. To be provided.

The upper front piece 21a, the lower front piece 21b, and the bottom piece 23 of the connecting member 2, and particularly, the bottom piece 23 is formed to be curved outward with a predetermined radius of curvature R21a, R21b, R23, respectively. Is preferred. Note that the curvature radii R21a, R21b, and R23 in the case of bending are:
Upper front wall 11a, lower front wall 11 of curved gutter main body 1
b and the radius of curvature R11a, R11b, R13 of the bottom wall 13
Set according to. Thereby, the gutter main body 1
Of the connection member 2 and the inner surface of the connection member 2 to prevent water leakage. Note that the gutter main body 1 and the connection member 2 can be further fixed with an adhesive or the like. When the rear wall 12 of the gutter main body 1 is formed to be curved outward, the rear piece 22 of the connecting member 2 is also formed to be curved outward.

Next, a method of connecting the gutter main body 1 and the connecting member 2 will be described. First, the two gutter bodies 1, 1
The connecting member 2 is installed on the eaves in such a manner that a gap is formed between the adjacent gutter main bodies 1 and 1 in accordance with the interval of the stopper 25 formed on the inner surface of the rear piece 22 of the connecting piece 2. Then, FIG.
As shown in FIG. 5, the rear piece of the connecting member 2 is attached to the lug 12a formed on the upper edge of the rear wall 12 of the gutter main body 1 while being positioned by the stopper 25 formed on the inner surface of the rear piece 22 of the connecting member 2. The engaging portion 22a formed on the upper edge of the 22 is locked. In order to fit the gutter main body 1 into the connection member 2 and rotate the connection member 2 along the gutter main body 1 while rotating the connection member 2 upward about this locking point, Expansion,
That is, the connecting member 2 is deformed so that the distance between the engaging portion 22a formed on the upper edge of the rear piece 22 of the connecting member 2 and the engaging portion 21c formed on the upper edge of the front piece 21 is increased. in this case,
The gutter body 1 may be deformed so that the interval between the ear 12a formed on the upper edge of the rear wall 12 of the gutter main body 1 and the ear 11c formed on the upper edge of the front wall 11 is reduced. As a result, FIG.
As shown in FIG. 5, the gutter main body 1 is fitted into the connection member 2, and the connection member 2 is made to follow the gutter main body 1 and connected to the ear 11 c formed on the upper edge of the front wall 11 of the gutter main body 1. Front piece 2 of member 2
By fitting the engaging portion 21c formed on the upper edge of the gutter 1, the adjacent gutter main bodies 1, 1 and the connecting member 2 are integrated.
At this time, since the walls 11a, 11b, and 13 of the gutter main body 1 are curved outward, the walls 11a, 11b, and 13 do not bend inward even when a force is applied during integration. Further, since a slight difference in the radius of curvature between each wall of the gutter body 1 and each piece of the connecting member 2 is absorbed, the adjacent gutter bodies 1 and 1 and the connecting member 2 can be integrated in a close contact state. .

When the adjacent gutter bodies 1 and 1 are connected by the connecting member 2, the pieces 21, 22 and 2 of the connecting member 2
While the protrusions 3 are in close contact with the walls 11, 12, and 13 of the gutter main body 1, the protrusions 24 also serving as the engagement portions hold the protrusion walls 15. Therefore, the upper surface of the upper front wall 11a of the gutter main body 1, the inner surface of the protruding wall 15, and the cover piece 24c of the connecting member 2
A water passage space 3 is formed by the inner surface of the gutter, and a gap between the stoppers 25 is formed between the adjacent gutter bodies 1.

As a result, the rainwater falling on the upper surface of the upper front wall 11a of the front wall 11 of the gutter body 1 is received by the auxiliary rainwater passage 16 formed in the gutter body 1 and received by the auxiliary rainwater passage 16. Rainwater can flow into and pass through the water passage space 3 formed at the position of the sub-rainwater passage 16 of the gutter main body 1 of the connecting member 2, and further, at a substantially intermediate position of the connecting member 2, the adjacent gutter main body Water can be drained to the main rainwater passage 10 formed in the gutter main body 1 through the gap between the gutters 1 and 1.

The rainwater falling on the upper surface of the upper front piece 21a of the connecting member 2 is received by the auxiliary rainwater passage 26 formed in the connecting member 2, and the rainwater received by the auxiliary rainwater passage 26 is received by the gutter main body. Along with the rain water that has fallen on the upper surface of the upper front wall 11a of the front wall 11, the auxiliary rain water passage 26 leads the auxiliary rain water passage 16 of the gutter body 1 to the position of the auxiliary rain water passage 16 of the gutter body 1 of the connecting member 2. The main rainwater formed in the gutter main body 1 can be made to flow into and pass through the formed water passage space 3 and at a substantially intermediate position of the connecting member 2 via a gap between the adjacent gutter main bodies 1 and 1. The water can be drained to the passage 10.

According to the connecting member of the gutter of the present invention, the middle part of the front piece of the connecting member is formed so as to protrude outward, and the rain water falling on the upper front piece of this front piece is removed. By being configured to be introduced into the secondary rainwater passage of the rain gutter, it is possible to reliably prevent rainwater from directly falling under the eaves along the outer surface of the connection member of the rain gutter, and to prevent the front piece of the connection member from falling. Rain water that has fallen on the upper front piece can be introduced into a secondary rain water passage formed in the gutter body and drained.

According to the rain gutter connection structure of the present invention,
After the rainwater that has fallen on the upper front piece of the front piece of the connecting member is introduced into the sub rainwater passage formed in the gutter main body, it can be drained to the main rainwater passage formed in the gutter main body. Further, by connecting the main gutter body formed in the gutter body to the main rainwater passage through a gap between the adjacent gutter bodies, the connection structure of the gutter can be simplified.
