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 an object of the present invention is to provide a rain gutter having a novel structure suitable for a snowy area. It is a thing.

(Prior Art) Rain gutters are designed to prevent raindrops from eaves in buildings.
It can be said that it is an indispensable building material, but in snowy areas it is often deformed by the phenomenon of falling snow on the roof surface, and in severe cases, it may fall off the eaves, and many measures are taken for that. People are having a hard time.

A traditional steel type gutter support made up of a gutter receiving part that fits on the outer circumference of the rain gutter bottom surface and an eaves fixing part that extends straight from the gutter receiving part and reaches the eaves and is fixed. Rain gutters installed with metal fittings cannot serve as rain gutters in snowy areas.

Therefore, as a proposal to prevent rain gutters from being damaged by the snow load, there is no way to make the above-mentioned conventional gutter receiving metal as sturdy as it is, but even if only the gutter receiving metal is made strong, There is a limit to the strength of the eaves that supports it, which comes from the top of the building,
Although there is almost no guarantee that the load of the sturdy gutter receiving bracket can be safely supported, in addition, it has a drawback that the appearance is awkward and the unit price is high, which is not enough as a rain gutter for snowy areas. It is something that must be done.

As another proposal, there is also a type shown in FIG. 5 in which a rain gutter is moved and stored under the eaves during a snowfall season.

As can be understood from the example in the figure, this type of moving and storing type has a much more complicated structure than the above-mentioned traditional type, and the unit price of the product is considerably expensive. Not only does it have a big drawback that the installation work is complicated and it makes the contractor cry, and as a further fatal drawback, it is long and continuous in one line along the eaves. If the rain gutter installed is not moved and stored along the entire length of the gutter, the rain gutter itself may be deformed. That is not the case, and it can be said that this is supported even by the fact that it has not been possible to confirm the fact that it has been commercialized so far.

As another proposal, the gutter receiving metal fitting is formed of a special plastic material having elasticity restoring property, and when the snow load is received, the eaves fixing part of the gutter receiving metal fitting is naturally elastically deformed. There is also a type that has an extremely novel structure that temporarily moves the rain gutter diagonally downward to escape the snow load.

This type was developed by the applicant of the present application, is more practical and effective than any of the types described above, and is gradually being widely adopted as a rain gutter in a snowy area.

However, even with this type, unless the optimum number of snowflakes is set and used according to the amount of snow, a large elastic deformation occurs, which hinders the expectation of average resilience. While it has some drawbacks such as water drainage, its installation work is extremely complicated (because it must be installed linearly in accordance with the water drop gradient), especially when the number of used pipes is large, making it even more practical. The development of rain gutters is highly anticipated.

In order to deal with the above situation, the present invention makes efforts to develop and research a rain gutter having a more practical structure, and finally succeeds in developing a rain gutter having a completely novel structure as described in detail below. It was done.

Hereinafter, the details of the configuration will be explained together with some embodiments.

(Object of the Invention) As will be clearly understood from some of the embodiments representative of the present invention shown in the drawings, the rain gutter of the present invention basically has the following configuration.

That is, the rain gutter main body 1 formed in a predetermined length with an appropriate cross-sectional shape such as a semicircle or a box-shaped cross section, and continuously extending from one end edge 11 or the vicinity of the end edge 11 in the cross-sectional shape of the rain gutter main body 1. And the eaves fixing part 2 having an elastically deformable portion 21 formed by bulging downward to form a rain gutter in which the eaves fixing part 2 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 is not limited to the so-called most general semi-circular shape, but also any shape such as a box shape or a part of which a step or rib for reinforcing or design effect is formed. There is no problem even if it is shaped, and it is made by cutting it to a suitable size from a long size to a standard size of about 1800 mm.

The eaves tip fixing portion 2 is formed by continuing one end edge 11 of the rain gutter main body 1 as it is (an example shown in FIG. 1) or a state in which the end edge 11 is continued from slightly lower than the end edge 11. (The example shown in FIGS. 2 and 3), and the elastically deformable portion 21 having a downwardly bulging cross-sectional shape and the nose cover that constitutes the eaves tip.
H1 or rafter H2 and a fixing piece portion 22 for nailing to a support portion such as a mouth of the rafter. In the figure, 23 is a nail attachment hole formed in the fixing piece portion 22.

The elastic deformation portion 21 of the eaves point fixing portion 2 has a cross-sectional shape that is advantageous for elastic deformation, for example, a balloon contour shape in which both sides are inflated as shown in FIG. 1, or as shown in FIG. It is formed to have a bulged cross-section only on one side, or to have a substantially U-shaped cross-section, which is not particularly shown.

The continuous structure between the eaves fixing part 2 and the rain gutter main body 1 is not limited to the one having a continuous structure at the molding stage as shown in each of the drawings as an example. It also includes a structure in which the portion 2 and the rain gutter main body 1 are separately molded and are connected to each other by mechanical means (for example, fitting, bonding, riveting, etc.) to be integrated and continuous. Needless to say, the boundary portion between the eaves fixed part 2 and the rain gutter main body 1 which is the continuous structure is such that the external force is surely elastic when the snow load is applied to the rain gutter main body 1. In order to be transmitted to the deformable portion 21, it is desirable that the reinforcing structure is appropriately formed, such as by having a hollow core in cross section.

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 having a high elasticity restoring property, for example, polycarbonate, plastic such as ABS resin, spring-like steel material or the like. In addition to forming the whole with the same material, only the eaves fixing part 2 is formed with a material having elastic resilience, or only the elastically deforming part 21 of the eaves fixing part 2 is made of a material having a great elasticity restoring property. It may be formed as described above.

Specific examples shown in the drawings will be described below.

(Embodiment 1) First, in the embodiment shown in FIG. 1 of the drawings, the eaves edge fixing portion 2 has no cutout portion 22a or cutout portion 21a over the entire length of the rain gutter main body 1 at all. It is an example of what was formed as a shape.

In the case of this structure, for example, when using plastics as a raw material, the product extruded through the die during extrusion molding is simply processed as appropriate, and cut into a predetermined length. Then, the rain gutter of the present invention is provided.

In the figure, 12 is the other edge, the upper end of which is a reinforcing portion.
While the 13 is formed, the main part of the trough of the gutter main body 1 is shown as an example formed in the reinforced core structure 14.

(Embodiment 2) In the embodiment shown in FIG. 2, a required portion of the elastically deformable portion 21 in the eaves tip fixing portion 2 is cut out along the length direction of the rain gutter so that a cutout portion 21a having an appropriate width is formed. , 21a ... is an example of a rain gutter formed to have.

The notch portion 21a formed in the elastically deforming portion 21 not only has a structure for saving the material and reducing the weight, but also has a function of adjusting the overall elastic performance and a function of draining water.

(Embodiment 3) In the embodiment shown in FIG. 3, important points other than the elastically deforming portion 21 in the eaves edge fixing portion 2 are cut out along the length direction of the rain gutter to form a notch having an appropriate width. A rain gutter formed so as to have portions 22a, 22a ....

In both the one shown in this embodiment and the one shown in the above-described embodiment, the connection of the eaves fixing part 2 to the rain gutter main body 1 is performed from the middle of one edge 11 of the rain gutter main body 1. According to the connected example, the end edge 11 is formed with a reinforcing portion 13 at its upper end, like the upper end of the other end edge 12,
Moreover, a reinforcing rib 15 is formed in the center of the lower surface of the rain gutter main body 1 in the direction along the axis, and from that portion to the connecting portion of the eaves fixing portion 2 at a portion near the eaves fixing portion 2, a reinforcing structure including the core structure 14 is formed. It is shown as formed.

The structure shown in this embodiment and the structure shown in the above-described second embodiment can of course be adopted as a structure in combination.

(Effects and Effects) The rain gutter of the present invention having the above-described configuration has its eaves fixing portion 2 as shown in the sectional view of the installed state of FIG.
Will be installed by nailing it to the nose cover H1 (in the case of the eaves where the back cover H1 is omitted, the rafter H2's mouth) which is a member of the eaves front of the building H.

Therefore, like the previous ones, the gutter receiving metal fittings are scattered at predetermined intervals and are fixed so as to match the predetermined tree drooping slope, and then the rain gutter is hung over, and then, depending on the case, wire No need for complicated double or triple work such as connecting them with each other. Match any part of the rain gutter with a predetermined water drip gradient, and put the nail 3 in the nail wearing hole 23 of the eaves fixing part 2 as it is. By inserting and nailing, the whole rain gutter is naturally fixed in a state where it is set to a predetermined water drop gradient. In the figure, H3 indicates the eave ceiling.

Once the rain gutter installed at the eaves end receives the snow load, it deforms the elastically deforming portion 21 of the eaves fixing part 2 and descends in the direction indicated by the arrow in the figure, so that the rain gutter main body 1
The state indicated by the chain double-dashed line, or a large amount of movement, will cause the snow from the roof surface covered by the rain gutter main body 1 to fall naturally and be released from the snow load. Therefore, the rain gutter main body 1 does not return to its original position due to the restoring force of the elastically deformable portion 21 and is not damaged at all, which makes it extremely reasonable as a rain gutter in a snowy area.

In this way, since the eaves edge fixing portion 2 having the elastically deforming portion 21 is formed over the entire length in the length direction along the one edge 11 of the rain gutter main body 1, the structure is complete. All of the complicated installation work such as those up to now is eliminated, and since the entire elastically deformable portion 21 is deformed in a related manner, partial over-deformation is prevented, and there is a concern that the restorability deteriorates partially. In addition to the above, the rain gutter main body 1 and the eaves tip fixing portion 2 are provided in the structure having the configuration shown in the first embodiment.
And are integrated manufacturing, which adds to the manufacturing advantage that they can be mass-produced.

Further, in the structure having the cutout portions 21a, 21a, ... As in the second embodiment, the elastically deforming portion 21 is less likely to be clogged with rainwater or dust, and the overall weight is reduced and material is saved. Not only will it have the advantage of being connected, but the number of cutouts 21a, 21a, ...
By exerting the excellent feature that the restoring force of the entire elastic deformation portion 21 can be adjusted by adjusting the size of 1a itself, the cutout portions 22a, 22 shown in the third embodiment are further exhibited.
In the case of forming a ..., It has an advantage that the processing means for weight saving or material saving becomes extremely simple.

As described above, the rain gutter of the present invention has a configuration that is almost ideal as a rain gutter in a snowy area, both in terms of its function and handling work, and is also suitable for mass production in terms of manufacturing. It has the advantage that it is suitable and can be provided at low cost, and it is expected that it will be adopted more and more as a rain gutter in snowy areas.
