Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a rain gutter, and particularly to a rain gutter that can be used both as an eaves gutter and as a toyohashi.

[Background technology]

Japanese Utility Model Publication No. 46-18016 proposes a rain gutter that can be used both as an eaves gutter and as a toyohashi.

This is a soft synthetic resin sheet with engaging parts on both sides that engage with each other, and a flexible core wire inserted inside the soft synthetic resin sheet to give it strength, making it easy to pack and transport. When used as a toyohashi at the construction site, the retaining parts on both sides are engaged with each other to form a closed tube, and when used as an eaves gutter, the engaging parts on both sides are A member is attached that engages with and maintains a predetermined distance between the two engaging portions.

However, the eaves gutters or toyohashi that can be obtained by this method are large, and it is not possible to obtain square-shaped ones, and since the whole is made of soft synthetic resin, it is difficult to make them square-shaped. If it is bent, there is a problem that it will break or crack, and even if it is not bent, it will inevitably be inferior in durability because it is made of soft resin, and it will have a core wire. However, it was prone to tearing and cracking.

[Purpose of invention]

The present invention was developed in consideration of these points, and its purpose is to not be bulky when packaged and transported, and to be able to be used as a square eave gutter or a square toyohashi. To provide a rain gutter which has a bent part made of soft resin for easy bending, but which does not cause tears or cracks due to application of excessive load to the bent part.

[Disclosure of invention]

Therefore, in the present invention, a plurality of bendable bending parts made of soft resin are arranged in parallel along the almost entire longitudinal length of a substantially plate-shaped rain gutter forming body made of hard resin, and the bending parts are arranged on both sides. A plurality of reinforcing ribs made of hard resin are provided on one surface of the rain gutter forming body to protrude over the entire length in the longitudinal direction, and are continuous to the rain gutter forming body via the rain gutter forming body and forming a hollow part between the rain gutter forming body,
It is characterized in that a locking protrusion is provided on one side over approximately the entire length of the gutter forming body in the longitudinal direction, and a locking recess into which the locking protrusion locks is provided on the other side. By using hard resin and only soft resin for the bent portions, we are able to maintain strength and accommodate square shapes, and the presence of reinforcing ribs prevents excessive loads from being applied to the bent portions.

The present invention will be described in detail below based on the illustrated embodiment. The rain gutter forming body 1 made of a hard resin such as hard vinyl chloride resin is formed into a horizontally long substantially plate shape, and
The three portions that divide the rain gutter forming body 1 into approximately four equal parts in the width direction are each formed into bent portions 2 made of soft resin over the entire length in the longitudinal direction.

A reinforcing rib 5 made of hard resin and having a substantially U-shaped cross section is provided on the inner surface of the bent portion 2 so as to protrude over its entire length.

Both sides of the reinforcing rib 5 are connected to the rain gutter forming body 1 via bent portions 2 made of soft resin.

On one side edge of the rain gutter forming body 1, a locking protrusion 3 having an oval-shaped tip is provided to protrude outward over almost the entire length in the longitudinal direction. Further, a recess 6 having an open top is provided.

Further, at the other end of the rain gutter forming body 1, a locking recess 4 whose upper part is open over substantially the entire length in the longitudinal direction is provided, and a locking piece 7 is provided at the outer upper end of the locking recess 4. It protrudes on the 4th side.

Furthermore, a decorative part 8 having sawtooth irregularities is provided approximately at the center of the rain gutter forming body 1 between the locking protrusion 3 and the adjacent bent part 2 over the entire length in the longitudinal direction.

Therefore, when constructing the eaves gutter 9 using the rain gutter forming body 1, the hanging fitting 10 having the abbreviated holding piece 11 is placed on the eaves as appropriate with the rising piece 11a of the holding piece 11 facing outdoors. Install multiple units at intervals.

Then, as shown in FIG. 2, the two bent parts 2 on the side of the locking recess 4 are bent at approximately right angles to form a square eave gutter 9 with the reinforcing ribs 5 on the inside. Insert the upper end of the rising piece 11a of the hanging fitting 10 into the recess 6, and insert the holding piece 1
By inserting the tip of the horizontal piece 11b of No. 1 into the locking recess 4,
The shape of the eaves gutter 9 is maintained and at the same time the eaves gutter 9 is attached to the edge of the eaves.

At this time, the locking protrusion 3 side located on the outdoor side protrudes higher than the locking recess 4 located on the eaves side, and the decorative portion 8 is located on the outdoor side and the hanging metal 10 is hidden in the eaves gutter 9, and is constructed to have a good appearance.

In addition, by changing the length of the horizontal piece 11b, the eaves gutter 9
The opening width can be adjusted.

When constructing Toyohashi 12 using rain gutter forming body 1, as shown in Fig. 4a, 3
The two bent portions 2 are each bent at approximately right angles to have a substantially rectangular cross section, and the locking protrusion 3 is inserted into the locking recess 4 and locked with the locking piece 7. The stop protrusion 3 is prohibited to form the Toyohashi 12, and this is attached to the outer wall of the building using a retainer (not shown) with the decorative part 8 facing outdoors.

[Effect of idea]

As described above, the present invention can be used as both Toyohashi and eaves gutters, and is not bulky because it can be packaged and transported in an unfolded approximately plate-like state. In addition, the main body is hard resin, and soft resin is only used for the bent parts, so it is possible to obtain square-shaped eaves gutters. In addition to having higher strength compared to other types, there is less risk of tears or cracks occurring in the soft resin part, and furthermore, both sides are connected to the rain gutter forming body through bent parts. Since reinforcing ribs made of hard resin are provided to form hollow parts between the rain gutter forming body, the gutter forming body is bent at the part connecting the reinforcing ribs and the rain gutter forming body among the bending parts. As a result, the folding lines clearly appear and the linear design becomes clear, and even if the bending part made of soft resin has a width to make it easier to bend, there are reinforcing ribs. The bent part does not sag or twist between the hanging fittings, and the presence of reinforcing ribs restricts the maximum bending angle of the bent part, so there is no possibility of bending the bent part too much. It does not cause breakage or cracks at the bent portion.
