Description

DESCRIPTION

Blind

TECHNICAL SECTOR

The present application refers to a blind with an improvement in its ventilation capacity, specially designed to prevent the entry of heat by radiation.

It is applicable in the housing and building industry.

STATE OF THE ART

The use of blinds is known, mainly in France and Spain, which allow to close the passage of light and heat inside a house or building. They are generally made up of a series of horizontal slats interwoven consecutively. The slats can be moved in a first direction, according to the horizontal joint line, so that the blind can be rolled up or unrolled as desired. This implies that each slat has an inner face (towards the axis of rotation when rolled, generally convex) and an outer face, normally concave.

This system makes it possible to stop the passage of solar radiation through the window or door, so it has a high efficiency to prevent the heating of the house in summer. However, this solution also prevents the establishment of air currents that help lower the thermal sensation inside the house. Therefore, it is necessary to improve the blinds.

The applicant does not know of any system that allows solving all these problems as easily as the invention.

BRIEF EXPLANATION OF THE INVENTION

The invention consists of a blind according to the first claim. Its different variants solve the problems outlined.

The blind of the invention is of the type formed by a plurality of slats and rollable. At least one slat has a series of through holes. The sections can be circular, square, elliptical, oval ... The most preferred solution is circular.

These through holes preferably have a first end on the outside of the slat with a larger section than the second end on the inside of the slat. Thus, there is an acceleration of the air flow that allows the room to be cooled better, lowering the temperature.

In that case, in one embodiment the ends are of constant section and are separated by an intermediate section of change of section.

The blind can be made up of different types of slats. For example, you can have slats with different hole densities (holes per square meter).

Other variants can be seen in the rest of the report.

MODES OF EMBODIMENT OF THE INVENTION

An embodiment of the invention will be briefly described below, as an illustrative and non-limiting example thereof.

Figure 1 shows an example of slat (1) for blinds, formed by a strip, which in use is horizontal, with a coupling on each longitudinal edge, as is known in the art.

The body of the slat (1) has a series of through holes (2), with a first end (21), on the outer side of the slat (1) (right part in figure 1) and a second end (22 ) on the inside of the slat (1). The section at the first end (21) is larger than at the second end (22), so that it acts as a funnel.

Preferably, the change in section occurs in an intermediate section (23), so that each end (21,22) has a constant section. This solution reduces the passage of light to the interior and facilitates the passage of air to generate a current.

The blind of the invention can have all slats (1) the same, alternate slats (1) with holes (2) and without holes (2), vary the density of holes (2) in each slat (1) or any suitable solution , according to the expected insolation and the current to be allowed or generated.

The slat (1) can have one or more moving parts (3), which open or close the passage of the holes (2). In this way, it is possible to block the passage of any minimal light. The movement of these moving parts (3) will normally be longitudinal to the slat (1), for example by guides (32). The moving parts (3) can be inside or outside the rest of the slat (1). In the open position (figure 2A), holes (31) in the movable part (3) align with the holes (2) in the body of the slat (1). In the closed position, the holes (31) are no longer aligned so the passage of air and light is cut off (figure 2B).

Claims (1)

1- Blind, of the type formed by a plurality of slats (1) and rollable, characterized in that at least one slat (1) has a series of through holes (2). 2- Blind, according to claim 1, characterized in that the holes (2) have a first end (21) on the outer side of the slat (1) with a larger section than the second end (22) on the inner side of the slat (1). 3- Shutter, according to claim 1, characterized in that the ends (21,22) are of constant section and are separated by an intermediate section (23) of section change. 4- Blind, according to claim 1, characterized in that it comprises slats (1) with different densities of holes (2). 5- Blind, according to claim 1, characterized in that it comprises a moving part (3) with a series of holes (3), with an open position in which the holes (3) are aligned with the holes (2), and a closed position in which they are misaligned.
