Abstract

Rainwater drain, which is applicable to the downpipes of gutters (2) for collecting rainwater, is characterized in that it is made up of a ring (3) that extends from below into a tubular body (1), which can be plugged onto the downpipe of the gutter, ring (3) from which a series of curved arms (4) and radial arms emerge from above in the form of voussoirs, which determine a support structure for a mesh (5) that is stabilized from above by means of coupling a cover (6).

Description

DESCRIPTION

Stormwater drain

TECHNICAL SECTOR

The present invention relates to a rainwater drain, specially designed to be installed on the roofs of buildings in general, when the evacuation or collection of rainwater is carried out by means of a downpipe.

The object of the invention is to provide a drain with the following features:

• Filters rainwater from the roof.

• Protects the downpipe from the entry of debris, snow or hail.

• Residues do not stick to or tangle on the surface of the protective filter.

BACKGROUND OF THE INVENTION

In the practical application of the invention, current drains do not prevent waste from entering the downpipe.

Debris adheres and becomes entangled in the structure of the drain, facilitating its accumulation, considerably reducing or eliminating the drainage capacity of the protector.

Furthermore, atmospheric phenomena such as snow or hail can block the downpipe when it freezes inside.

EXPLANATION OF THE INVENTION

The proposed rainwater drain fully and satisfactorily resolves the aforementioned problem, based on a simple but highly effective solution.

To this end, the device of the invention is made up of two main elements, a structure, preferably made of PVC, which includes a ring and a cap, and a mesh, preferably made of nylon.

The ring constitutes the connection element of the device with the lower part in the drain of the gutter joint with the downpipe.

This ring serves as a support for a cap made up of several radial arms like voussoirs that end in a top cap, and which serve as a support structure for the nylon mesh, defining a prominent element that deflects towards the sides of said cap the leaves and dirt that may fall onto the drain, preventing the entry of debris, snow and hail.

The special configuration prevents debris from sticking or becoming entangled on the surface of the nylon mesh, allowing rainwater to be collected directly into a well or cistern, even when the gutters contain debris.

BRIEF DESCRIPTION OF THE DRAWINGS

To complement the description that follows and to aid in a better understanding of the characteristics of the invention, according to a preferred embodiment thereof, a set of drawings is included as an integral part of said description, in which, for illustrative and non-limiting purposes, the following has been represented:

Figures 1 and 2 show elevation and profile sections of a rainwater drain made in accordance with the object of the present invention.

Figure 3 shows a top plan view of the device in the previous figures.

Figure 4 shows, finally, a bottom plan view of the device from the previous figures.

PREFERRED EMBODIMENT OF THE INVENTION

In view of the figures described, it can be observed how the device of the invention is constituted from a ring (3) that extends below into a tubular body (1), an assembly that has external dimensions in accordance with the internal dimensions of the downpipe (2’) of the gutter (2) in which it is installed by means of plugging, a ring from which a series of curved (4) and radial arms emerge above as voussoirs, which serve as support for a mesh (5) that is stabilized above by coupling a cover (6).

As previously stated, the mesh carrier structure will preferably be made of PVC, while the mesh itself will preferably be made of nylon.

For illustrative purposes only, the mesh could be obtained from a cloth of approximately 25cm x side and 6x6 threads cm2.

More specifically, for the assembly of the device, the hat formed by the curved arms (4) is placed on its base, in the center of the mesh, at an equidistant distance from the sides.

Next, the edges of the mesh are brought to the top of the hat, which has a blind hole. The excess mesh is inserted into this hole, and the cap (6) or embellishment is placed over it to secure it, taking special care not to overtighten the mesh. It should remain loose to absorb the surface tension of the water.

Next, the hat is assembled to the ring (3) and the protective filter is ready to be installed.

Returning to the surface tension of water, this physical phenomenon is accentuated when the water collides with the solid surface of the protector, trapping the residue around it and compromising its function.

The device of the invention does not reduce the flow entering the downpipe because it has no solid parts interfering with the water's entry. The nylon mesh (5) breaks the surface tension of the water, preventing debris from adhering to it.

The mesh configuration (5) in the hat provides a double filter, maintaining its function even when the exterior of the mesh has deteriorated.

In installations that are difficult to access or on roofs, where, due to their design or size, the evacuation of rainwater is of particular importance, the protective filter prevents the entry of debris into the downpipe, ensuring the evacuation of the roof.

The device described can be manufactured in different dimensions to adapt to the different diameters of downpipes that are marketed.

The materials described for both the mesh and its support structure are only examples, as there are many other common building materials that could be equally valid.
