Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rain gutter attached to the eaves for receiving rain water from a roof.

[0002]

2. Description of the Related Art Rain gutters, which are also called eaves gutters, are generally made of galvanized steel plate or copper plate, but plastic products are also frequently used. Regarding the shape, there are a circular gutter with a semi-circular cross section, and a square gutter with both side walls standing slightly open on the bottom wall.

To attach the rain gutter, a gutter receiving metal fitting in which a semicircular arc-shaped receiving portion into which the rain gutter is fitted is welded to the tip of a supporting arm is used. There are various shapes of the supporting arms, and there are a supporting arm provided with a mounting hole for nailing or screwing on the side surface of the rafter, and a thin arm having a tip so that the rafter can be driven from the end surface. It is also tied with wire to hold the gutter in the receiving part.

[0004]

According to the conventional rain gutter as described above, since the groove opening is wide, there are fallen leaves,
Dust such as plastic bags that have been blown by the wind tends to fall, and the accumulation of dust will hinder the drainage of water, and if snow falls in a rain gutter in the snowfall region, it freezes and becomes a weir. However, there is a problem in that the drainage becomes a hindrance, and these obstacles cause rainwater to overflow to the roof side, causing decay of the house.

When the roof is covered with snow for a long period of time, the lower layer of the roof gradually slides down while it freezes, and at the eaves, it may hang down to the back side of the roof, but in this case, it falls to the edge of the rain gutter. Snow is caught and an excessive load is applied to tilt or bend the rain gutter, which also causes rain water to overflow, and it is not uncommon for the rain gutter to come off during heavy snowfall.

The present invention has been made in view of the above circumstances.
The purpose of the invention is to provide a rain gutter in which the backwater works well by removing the cause of the overflow of rainwater as much as possible.

[0007]

In order to achieve the above object, the present invention provides a main body groove wall having the widest inner width at the upper end and a main body in a shape that can be a gutter by aluminum extrusion molding. It is characterized in that it is integrally formed with a counter wall that extends from the wide front end of the groove wall and slopes high toward the roof.

[0008] In addition, a mounting wall extending from the widest rear end of the main body groove for nailing or screwing the upper end portion to the front end surface of the eaves front end of the eaves is integrally formed, and The mounting wall may be formed to be inclined inward of the groove so as to match the front end face.

Further, the main body groove wall may be formed in a semi-circular cross section as a part of a laterally long elliptical shape, and the anti-upward wall may be curved as an extension of the circle.

[0010]

[Operation] Since the rain gutter is configured as described above, the drainage capacity can be secured at least in the width of the main body groove wall, and since it has the anti-climbing wall, the gap between the rain gutter at the tip of the eave tile is It can be installed so as to be narrow, which prevents the entry of dust such as fallen leaves,
In addition, since the amount of snowfall in the rain gutter is reduced, the overflow of rain water is prevented and the drainage is performed smoothly.

Since the outer edge enters the inside by the anti-upward wall, falling snow is less likely to be caught, so that the rain gutter can be prevented from tilting, falling off, and bending. In particular, when a mounting wall is provided (Claim 2) and the counter-upward wall is curved (Claim 3), it becomes a rib and may be directly mounted at the upper side. Certainty can be obtained to prevent the overflow. In addition, a gutter receiving metal fitting and a wire binding are not required, and the rain gutter can be quickly and firmly attached by the attachment wall.

[0012]

Embodiments of the present invention will now be described with reference to the drawings.

The drawing shows one embodiment, in which a rain gutter C is formed by aluminum extrusion molding, and an anti-upward wall 4 is provided at the front end of a lower main body groove wall 3 and a mounting wall 5 is provided at the rear end thereof. Has a cross-sectional shape that extends. In this case, it can be regarded as a deformation of a circular gutter, but it can also be implemented as a deformation of a square gutter. It should be noted that the main body groove wall 3 and the other anti-upward wall 4 and the mounting wall 5 are tentatively distinguished from each other at the position where the inner width is widest.

The main body groove wall 3 is formed in a semi-circular shape corresponding to the conventional circular gutter, but even if it is called an anti-circular arc, in this case, it is the shape of the laterally long elliptical lower half part. In this way, the overall depth is moderately adjusted. The position of the main body groove wall 3 is preferably about the same as that of the conventional rain gutter, and by doing so, the counter-upward wall 4 can effectively prevent falling of dead leaves and the like.

Due to the shape of the anti-upward wall 4 which is warped toward the roof side, not only the groove opening width of the rain gutter C is narrowed, but also the interval W with the eave roof tile 6 is narrowed. The eave roof tile 6 has a raindrop piece 7 at its tip, and is set so that the lower end of the raindrop piece 7 and the upper end of the anti-climbing wall 4 are substantially at the same position. By doing so, the rainwater surely flows into the rain gutter C, and the fall of dead leaves and the like is easily prevented.

Further, the shape of the counter rising wall 4 is formed as an extension of a semicircular arc as a sectional shape of the main body groove wall 3. This makes it difficult for the snow falling off the roof to be caught on the counter wall 4. The snow accumulated on the roof drastically droops while drawing an arc so that it turns to the back side of the eaves while gradually slipping down as a result of freezing of the lower layers in the extremely cold season, and thus the outer surface of the front end of the rain gutter C becomes a circle or a circle. With a close curved surface, in particular, such a drooping freezing snow is not caught. However, even if the anti-upward wall 4 has a straight shape, it is not caught as compared with the conventional rain gutter C, so it is not against the spirit of the present invention.

The mounting wall 5 is to be nailed or screwed to the end surface of the wide and narrow dance 9 at the eaves end, and the mounting wall 5 is provided so as to incline toward the inside of the groove in accordance with the inclination of the end surface. In the figure, 10 is a hole for nailing or screwing. Further, since the mounting wall 5 is formed longer than the counter-up wall 4, rainwater never overflows to the house side.

With respect to the mounting strength to the eaves, since the mounting position is, as it were, a suspension mounting at the inside position of the main body groove wall 3, from the viewpoint that there are branches or points of action due to the load on the end face of the wide and small dance 9. Since the boosting force is not applied so much to both points, it does not peel off against the force of nailing and the like, and the stable attachment state is maintained. The rain gutters C continuous in the lateral direction can be connected to each other by welding means.

Incidentally, unlike this embodiment, the rafter 1
When the mounting wall 5 is formed so as to be mounted on 1,
Due to the principle of leverage, etc., a stable mounting state cannot be obtained, and the inconvenience of rainwater overflowing on the house side cannot be prevented. In addition, in the case of this embodiment, a draining plate 13 which also serves as a reinforcement is used to attach the rain gutter C, and the draining plate 13 is nailed or screwed to the wide and small dance 9 over the entire length of the rain gutter C.

The draining plate 13 is made of aluminum,
In the form of abutting on the upper end of the wide and narrow dance 9, it is formed into a slightly acute-angled refraction cross-sectional shape, and a foldback 15 is provided at the rear end. As for the attachment, the rain gutter C is nailed or screwed with the attachment wall 5 being pressed. 17 is the stop hole.

As described above, the water in the rain gutter C does not overflow to the house side, but if strong wind and rain are blown in,
There is a risk that rainwater may go back up the mounting wall 5 and enter the stop hole 10 of the nail 19 or the upper edge of the nail 19 and the small and wide dance 9. If this happens, the wide and small mai 9 will rot, and as a result the mounting strength of the rain gutter C will deteriorate. Therefore, such a draining plate 13 is used with care.

As for the attachment of the draining plate 13, it is possible to attach the draining plate 13 on the mounting wall 5 of the rain gutter C with the nails 19 in advance on the wide and small dance 9 in advance, and then attach the draining plate 13 and stop with the screw 21 to infiltrate the rainwater. It is desirable from the viewpoint of prevention. Further, from the viewpoint of reinforcement, it is desirable to nail or screw the upper surface of the wide and small dance 9.

[0023]

As described above, the rain gutter of the present invention has the following excellent effects.

Not only can the drainage capacity be secured at least in the width of the main body groove wall, but since the front end of the main body groove wall has a counter-upward wall, it can be installed by narrowing the opening width in relation to the eave roof tiles, and It prevents the ingress of dust such as vinyl and vinyl pieces, and because the amount of snowfall in the rain gutter is reduced, they do not hinder drainage, preventing rainwater from overflowing and draining water. It is done without delay.

This is particularly effective in heavy snowfall areas, and even when the snow on the roof frozen in the lower layer hangs down from the eaves, it has a counter-up wall, so falling snow is less likely to be caught, and therefore the rain gutter associated with heavy snowfall. It is possible to prevent tilting, falling off, bending, cracking, etc. Further, since it is made of aluminum, it is hard to rust and has excellent durability, and since it is difficult for dust to enter, it is easy to manage the rain gutter. Moreover,
It is environmentally friendly, recyclable, and, in combination with its shape, it has excellent aesthetics.

In particular, when the mounting wall is provided (Claim 2) and the counter-upward wall is curved (Claim 3), the above effects become remarkable, and the rain gutter is inclined or dropped. Certainty is obtained to prevent bending and overflow of rainwater,
In addition, it can withstand loads such as snow, icicles, and ladders. Also, since the rain gutter can be mounted quickly and firmly by the mounting wall, it is suitable for shortening the construction period and reducing the construction cost.
