Abstract

The device comprises a tab (1), which has raised flanges (8), arranged at the outlet of the water channel (5) of a top enclosure with a slope that bridges the distance between the header (2) and the beam (10) in such a way that it collects the water from the water channel directing it towards the beam (10) where by capillary effect it runs down the side of the beam (10) to a lower gutter (6) that runs longitudinally along the beam carrying the water towards a drain or towards the ground.

Description

As its name indicates, the device comprises a tab for drainage of slats, preferably movable, of structures with top enclosure and sun protection that facilitates the evacuation of water and prevents unwanted splashing inside the structure
Said tab is located at the ends of the water channel of the slats and is arranged in such a way that it bridges the distance between the end of the water channel and the surface, normally upright and perpendicular to this channel, such as the side of a beam or other type of profile, and which is part of the clamping frame of the slats.
The rainwater that falls on the pergola is channelled through the water channel of the slats to at least one of its ends, to then pass through said tab and the surface perpendicular to said channel, to a gutter which collects it and carries it towards a downspout.
The problem lies in the fact that, in the passage of the water channel of the slats to the gutter or drainage element, there may be drips and splashes towards the interior of the pergola.
The invention claimed comprises a tab that channels the water from the end of the water channel of the slat to the side of the surface perpendicular to the channel and at that point, due to the geometry of the tab, it presses on the water drop breaking its surface tension so that the water, by capillary effect, runs down said surface to the gutter avoiding splashes.
The field of action of this device is, preferably, that of structures with top enclosure or pergolas, although it can be applied to any drainage channel that one wants to evacuate without splashing on a lower channel.

BACKGROUND OF THE INVENTION

Currently, there are several devices that direct the fall of rainwater in a structure with a top enclosure by means of channels that help to evacuate water.
Patent WO02092938 consists of a roofing device comprising a plurality of roll-up or roll-out roof elements arranged successively with an inclination which by gravity directs water to the side channels on the sides.
In this case, there is no indication of an element that additionally prevents the impact of the water droplets in their passage from the roof towards the side channels which can cause splashes towards the inside of the enclosure.
European patent EP2589720 consists of an adjustable blade-shaped device that forms a protective roof, which at one of its ends has a part that helps the evacuation of water that due to its structure prevents the directing and increase of water on the lower surface of the blade.
This type of arrangement that prevents the water droplets from returning through the bottom of the blade does not solve the problem of splashing since it is not close enough to the side of the beam nor to the main water channel where the rainwater discharges.
To improve this arrangement in the anti-drip structure, patent WO2014136095 presents a structure with slat top enclosure, comprising several slats rotatably arranged, a slat gutter on a first longitudinal side and inclined towards an exit opening, and a side gutter extending essentially perpendicular to the slats under the respective exit openings, and that, facing away from the slats, an upright outer side wall is positioned, extending at least partly next to the slats, wherein said slat roof has increased tightness at the location of the slat drain to the side gutter due to one or more seals extending at least below the outlet opening of each slat extending from each slat to a location adjacent to said upright outer side wall.
This structure does not have a top flap on the sides of the slats that prevents the water from pouring over the sides where there is no anti-splash seal, in addition, in the event that the seals become obstructed by dirt, the device becomes more likely to cause unnecessary drips outside the area of the channels that direct the rain water.
Likewise, utility model ES1208711 , which consists of a structure with top enclosure and water collecting profile consisting of a water collecting profile on the sides of the beam which has a mesh that breaks the drop minimising the splash thereof, can also be affected by the plugging of said mesh by dirt, generating an increase in splashes towards the inside of the structure.

DESCRIPTION OF THE INVENTION

To resolve the aforementioned drawbacks, the invention consists of an anti-splash device arranged in a top enclosure, being preferably designed for a slat pergola and preferably for movable slats.
In this type of pergolas it is common to find a frame or structure composed of beams and pillars, with the slats resting on the beams preferably in a bushing.
We will call beam any element that serves as a support whereon the slats rest either directly or through an associated structure such as a profile. In general, this element will comprise a vertical surface arranged perpendicular to the slats, although there may be embodiments wherein this surface is not perfectly vertical nor perfectly perpendicular.
In movable slat pergolas, the beams, accommodate the bushings for housing the slat shafts.
The ends of the slats have closing parts called headers, it being typical for the slat shaft to be supported by the headers.
The device that is claimed comprises a tab between the header and the beam, bridging the distance between both.
Each of the slats has a longitudinal channel that collects the rainwater and directs it towards at least one of the ends of the slat that is open. We will call that longitudinal channel water channel and its open end or ends outlet or outlets.
The tab is arranged at the outlet of the water channel, bridging the distance between the header and the beam in such a way that it collects the water from the water channel and directs it against the beam.
The water from the channel runs down the tab and, when impacting against the beam, runs down the side thereof by capillary effect to a lower gutter that runs longitudinally along said beam, totally or partially, and carries the water towards a drain to the ground preferably arranged in one of the pillars. This facilitates the drainage avoiding generating splashes inside the pergola.
The tab has a slope from the water channel to the beam. It also has raised flanges by way of a parapet that facilitate the channelling of water towards the beam, preventing it from overflowing on the sides and falling directly into the gutter, generating splashes.
The tab is located between the end of the slat and the beam, bridging the gap between the two.
In a possible embodiment, the header has an upper extension by way of a fin that carries the water that can run along the surface of the slat towards the water channel, preventing it from falling freely from the end of the slat towards the gutter and splashing.
In a possible embodiment, the fin is located over the entire side of each of the slats collecting and guiding the water that can move along the sides towards the gutter, in the case, for example, that there is no upper extension of the header.
The tab may be in the form of a ramp, with or without grooves, or any other shape that generates a slope such that it allows the running and channelling of water from the water channel to the beam.
In a preferred embodiment, the tab is shaped as a downward convex curve.
The tab is secured by one of its ends to the header at the point wherein the water channel pours, such that it enables the passage of water from the channel to the tab. The other end of the tab is in contact with the inner side of the beam. The drain gutter is located at a lower level of the same inner side of the beam.
The device may be installed at the time of mounting the pergola or may be subsequently installed at the customer's discretion.
In this way, the water that falls on the pergola slats runs by gravity towards the channel that each one of the slats has and then pours onto the tab that channels the water towards the beam. The side flanges of the tab prevent it from overflowing laterally by falling into the gutter and splashing.
In a possible embodiment, the tab has longitudinal grooves that guide the water over this surface, meaning that when the water reaches the other end of the tab, which is in contact with the side of the beam, it will break the surface tension and by capillarity the water will run down said side of the beam until it reaches the gutter.
In the path of the water from the time it impacts the slats passing over the tab to the gutter, a constant contact of the water is maintained with the surfaces of the slat, the water channel, the tab and the inner side of the beam avoiding dripping and splashing.
To maintain a constant and adequate pressure of the tab on the beam, the tab is preferably made of flexible material.

DESCRIPTION OF AN EMBODIMENT OF THE INVENTION

An embodiment of the invention is proposed here that is neither unique nor limiting, but merely explanatory.
The invention relates to an anti-splash device arranged in a pergola of movable slats, where it is common to find a frame comprising pillars and beams where the latter have supports for the bushings housing the shafts of the movable slats.
The movable slats (4) have at their ends headers that close the piece laterally, the slat shaft being supported by the headers. The device comprises a tab (1) between the header (2) and the inner face (3) of the beam (10), bridging the distance between them.
The tab (1) is made of flexible material, and presses against the inner side (3) of the beam (10).
Each movable slat has a water channel (5) which is the longitudinal channel that collects all the rain water falling on the movable slats and directs it towards at least one of the ends of said slats.
The tab (1) is located at the outlet of the water channel and bridges the distance between the slat, in particular from the header (2) and the inner face (3) of the beam and directs the water from the water channel against that inner face of the beam.
In this way, the water that falls on the moving slats (4) runs through the water channel (5) towards the tab (1) where it runs towards the inner face (3) of the beam, falling against it and breaking the surface tension of the water that, due to capillarity, runs down the inner face (3) of the beam towards a gutter (6) located at a level lower than the tab (1). This gutter (6) runs longitudinally along the inner face (3) of the beam (10), at least from the point where the tab is located, to a drain such that water falling into the gutter is carried to a drain, preferably arranged in the pillars thus preventing generating splashes inside the enclosure.
The tab (1) has a convex curved shape on a slope that goes from its highest point at the outlet of the water channel (5) of each of the slats to its lowest point which is the point of contact with the inner face (3) of the beam. In a possible embodiment, the grooves (7) on its top face facing downstream allow the water to be directed uniformly.
The tab (1) further comprises flanges (8) that prevent water from overflowing and falling directly into the gutter (6) causing splashes inside the enclosure.
In the water path from the time it impacts the slats (4) passing over the tab (1) to the gutter (6), a constant contact of the water is maintained with all the surfaces it crosses, avoiding unwanted drips and splashes.
The slats have, at their ends, at their top part, fins (9) that act as barriers. These fins are preferably an extension of the headers, which act by preventing water from the top part of the slat from falling freely over its ends. To do this, these fins carry the water towards the water channel (5).
The tab is fixed to the slat through removable means, such as screws, which allows on the one hand its mounting at the time of construction of the assembly or its inclusion at a later time, in the same way as it that allows the maintenance and easy replacement of a tab that may have been damaged.
