Abstract

PURPOSE:To prevent the occurrence of breakage, by a method wherein a title gutter comprises a gutter main body formed in a semicircle or a box-shape in cross section and an eaves securing part expanded downward from a position in the vicinity of the one edge of the gutter main body to form a resilient deforming part, and release from a snow load causes restoration of the gutter to its original position. CONSTITUTION:A gutter comprises a gutter main body 1 formed in a semicircle or a box-shape in cross section and an eaves securing part 2 expanded downward from a position in the vicinity of the one edge 11 of the main body 1 to form a resilient deforming part 21. The gutter is formed integrally by a material, e.g. polycarbonate, having abundant resilient restoring force, or formed separably by the material to form an integral one-piece. When a snow load is exerted, through deformation of the deforming part 21, the main body 1 is lowered, snow on a roof surface with which the main body 1 is covered is naturally dropped, and the deforming part is restored to its original position by means of the restoring force of the deforming part 21. This constitution enables prevention of the occurrence of breakage.

Description

[Detailed Description of the Invention] (Object of the Invention) The present invention relates to a rain gutter installed at the eaves of a building, and aims to provide a rain gutter with a new structure particularly suitable for snowy areas. It is something.

(Prior art) Rain gutters are used to prevent rain from dripping from the eaves of buildings.
Although it can be said to be an indispensable building material, in snowy regions, it can become deformed due to the slipping of snow accumulated on the roof surface, or in severe cases, it can come off from the eaves, so there are measures to prevent this. Many people are struggling.

The gutter holder, which is a traditional type, is made of steel and consists of a part that fits on the outer periphery of the lower surface of the rain gutter, and an eaves fixing part that extends linearly from the part and reaches the eaves and is fixed. Rain gutters that are installed with metal fittings cannot function as rain gutters in areas with heavy snowfall.

Therefore, as a proposal to prevent rain gutters from being damaged by snow loads, it is possible to make the metal fittings of the conventional gutter holders as described above strong, but with gutter holders, it is possible to make only the metal fittings strong. However, there is a limit to the strength of the eaves that supports it due to the support strength from the top of the structure, and there is almost no guarantee that a sturdy gutter support can safely support the load of the metal fittings, and in addition, it may be unsightly in appearance. However, it also has the disadvantage that the unit price is high, and in the end, it has to be made inadequate as a rain gutter for snowy areas.

Another proposal is the type shown in Figure 5, in which the rain gutter is moved and stored under the eaves during the snowy season.

As you can see from the example in the figure, this type of moving and storing type has a much more complex structure and is considerably more expensive than the traditional type mentioned above. In addition to having the major disadvantage of not being a reliable scale and making the installation work complicated and frustrating for the contractor, an even more fatal disadvantage is that it is a long, tree-like structure that runs along the edge of the eaves. This method is not suitable for practical use because there is an operational problem in that unless the installed rain gutter is moved and stored almost simultaneously over its entire length, there is a risk of deforming the rain gutter itself. This cannot be said to be the case, and the fact that we have not been able to confirm that it has been commercialized to date supports this fact.

Another proposal is that the metal fittings of the gutter holder are made of a special plastic material that has elasticity, so that the eave fixing part of the gutter holder naturally becomes elastic when subjected to snow loads. Some types have extremely innovative configurations that deform and occasionally move the gutter diagonally downward to naturally escape the snow load.

This type was developed by Usu et al., the applicant of the present application, and is more practical and effective than any of the above-mentioned types, and is gradually beginning to be widely adopted as rain gutters in snowy areas.

However, even with this type, unless the optimal number is set and used according to the amount of snow, there will be areas where elastic deformation becomes large, which will hinder the expectation of average recovery performance. However, the installation work is extremely complicated (especially when a large number of units are used).
(This is because rain gutters must be installed in a straight line according to the slope of the water dripping.) Therefore, the development of even more practical rain gutters is long-awaited.

In order to cope with the above-mentioned situation, this invention has made efforts to develop and research a rain gutter with an even more practical structure, and has finally succeeded in developing a rain gutter with a completely new structure as detailed below. This is what I did.

The details of the configuration will be explained below along with some examples.

(Object of the Invention) As clearly understood from several representative examples of the invention shown in the drawings, the rain gutter of the invention basically has the following configuration.

That is, the rain gutter main body 1 is formed to have a predetermined length with an appropriate cross-sectional shape such as a semicircular or box-shaped cross section, and the rain gutter main body 1 has a rain gutter main body 1 that extends continuously from one edge 11 or the vicinity of the edge 11 in the cross-sectional shape. The elastically deformable portion 2 is made to have a cross-sectional shape that bulges downward.
1 and an eaves fixing part 2, which is integrally formed over the entire length of the rain gutter main body 1.

The cross-sectional shape of the rain gutter main body 1 may be of any type, such as a box shape or a part thereof with steps or ribs for reinforcement or design effect, in addition to the so-called general semicircular shape. There is no problem with cross-sectional ones, and 1800 mm from long ones.
It can be cut to an appropriate size up to a standard size of about mm.

The eaves fixing part 2 is formed by continuing one edge 11 of the rain gutter main body 1 as it is (as shown in FIG. (Example shown in Fig. 2-3), the elastically deformable part 21 has a downwardly bulging cross-section, and the support part such as the end of the fascia Hl or the rafter H2 constituting the eaves is struck. It is composed of a fixing piece part 22 that can be attached. In the figure, 23
is a hole for punching formed in the fixed piece part 22.

The elastically deformable portion 21 of the eaves fixing portion 2 has a cross-sectional shape that is advantageous for elastic deformation, for example, a balloon profile with both sides inflated as shown in FIG. 1, or a balloon profile as shown in FIG. One side only or one with a bulged cross section, or also,
Although not particularly shown in the drawings, it is formed with a substantially U-shaped cross section.

The continuous structure between the eaves fixing part 2 and the rain gutter main body 1 is not limited to the structure that is integrated and continuous at the molding stage, as shown as an example in each drawing. It also includes structures in which the part 2 and the main body 1 of the rain gutter are molded separately, and are connected and integrally connected by mechanical means (for example, fitting, gluing, riveting, etc.) so that they are continuous. Needless to say, the boundary between the eaves fixed part 2 and the rain gutter main body 1, which has a continuous structure, is such that when a snow load is applied to the rain gutter main body 1, the external force is reliably elastic. In order to transmit the heat to the deformed portion 21, it is preferable that the cross-section has a hollow core or other appropriately reinforced structure.

The rain gutter of the present invention, which is composed of the rain gutter main body 1 and the eaves fixing part 2, is made of a material with high elasticity and recovery properties, such as polycarbonate, plastics such as ABS resin, and spring-like steel, as appropriate. In addition to the whole structure being made of the same material, the eave fixing part straddle is made of a material with elasticity, and the elastic deformation part 2 of the eave fixing part 2 has elasticity = 7 - resilience. It may be formed by using a rich material.

Hereinafter, specific embodiments shown in the drawings will be described.

(Embodiment 1) First, in the embodiment shown in FIG. 1 of the drawings, the eaves fixing part 2 is a single plate having no cutout part 22a or cutout part 21a over the entire length of the rain gutter main body 1. This is an example of a device formed as a shape.

For example, in the case of a product made of plastic, the product is simply extruded through a die and cut into a predetermined length after being processed as appropriate. It is processed into the rain gutter of this invention.

In the figure, reference numeral 12 indicates the other edge, and a reinforcing part 13 is formed at the upper end, while the main part of the valley part of the rain gutter main body 1 is formed in a reinforced core structure 14 as an example. It is shown.

(Actual If, Mode 2) What is shown in FIG. 2 is a structure in which important points of the elastic deformation part 21 in the eaves fixing part 2 are cut out along the length direction of the rain gutter, and the cutout is cut out with an appropriate width. Parts 21a, 21a...

The cutout portion 21a formed in the elastic deformation portion 21 is not only configured to save material and reduce weight, but also functions to adjust the overall elastic performance and drain water.

(Embodiment 3) In the embodiment shown in FIG. 3, important points other than the elastic deformation part 21 in the eaves fixing part 2 are cut out along the length direction of the rain gutter, and the cutout has an appropriate width. Parts 22a, 22a...
It is a rain gutter formed as having...

In both the embodiment shown in this embodiment and the embodiments described above, the eaves fixing part 2 is connected to the rain gutter main body 1 from the middle of one edge 11 of the rain gutter main body 1. This is due to the connected example, and this edge 11 has
Similar to the upper end of the other edge 12, a reinforcing part 13 is formed at the upper end, and a reinforcing rib 15 is formed in the direction along the axis at the center of the lower surface of the rain gutter main body 1, and then a part near the eaves fixing part 2. The area up to the connection part of the eaves fixing part 2 is reinforced with #14 core! It is shown as being formed in f4 construction.

Note that it is of course possible to adopt the structure shown in this embodiment and the structure shown in the second embodiment described above as a structure in which they are used together.

(Function and Effect) The rain gutter of the present invention having the above-mentioned configuration has the eaves fixing portion 2 as shown in the sectional view of the installed state in FIG.
Fascia Hl (fascia H
In the case of an eave where l is omitted, it will be installed by attaching it to the end of the rafter 112.

Therefore, like in the past, the gutter holder is made by installing metal fittings at predetermined intervals and fixing them so that they match the predetermined dripping slope, then hanging or passing the rain gutter, and then, when Depending on the case, the complicated work of double or triple work such as connecting the two with wire etc. is completely unnecessary. Align any part of the rain gutter with the predetermined drip slope, and then attach the hole 23 of the eaves fixing part 2 as it is. Insert nail 3 into
The entire rain gutter is naturally fixed at a predetermined drip slope. In the figure, H3 indicates the eave ceiling.

When the rain gutter installed at the eaves in this way receives a snow load, it deforms the elastic deformation part 21 in the eaves fixed part 2 and descends in the direction shown by the arrow in the figure, and the main body 1 of the rain gutter The state shown by the two-dot chain line, or even more significant movement, will cause the snow that was covering the rain gutter body 1 to fall naturally from the roof surface, and the snow load will be released. Therefore, the rain gutter main body 1 returns to its original position by the restoring force of the elastic deformation portion 21, and is not damaged, making it extremely suitable for use as a rain gutter in snowy areas.

In this way, the structure is such that the eaves fixing part 2 having the elastically deformable part 2J is formed along the entire length along one edge 11 of the rain gutter main body 1. The complexity of installation work like that of other products is completely eliminated,
In addition, since the entire elastic deformation section 21 is deformed in a related manner,
In addition to preventing partial over-deformation and eliminating the worry of partial deterioration of restorability, in the structure shown in Embodiment 1, the rain gutter main body 1 and the eaves fixing part 2 are It also has the added advantage of being able to produce in large quantities through integrated manufacturing.

Further, a cutout portion 21a as in the second embodiment.

As shown above, the rain gutter of the present invention has a structure that is close to the ideal for a rain gutter in a snowy area, both in terms of its function and handling, and is also suitable for mass production in terms of manufacturing. 2. It has the advantage of being suitable for use and can be provided at low cost.
It is expected that it will be increasingly used as rain gutters in areas with heavy snowfall.
