ES2357590A1 - Slatted blind - Google Patents

Abstract

The present invention relates to a slatted blind that, unlike blinds known in the prior art, has the slats connected only by the ends thereof. The method of connection between the slats makes it possible, when the blind is raised, for there to be gaps between the slats for the purpose of ventilation. The same method of connection between slats establishes, at the bottom, a blocking method for preventing the blind being raised from the outside in an unauthorized manner.

Description

Louver blind.

Object of the invention

The present invention relates to a blind of slats that, unlike the blinds known in the state of the technique, it has the lamas linked only through its extremes The way of linking between the slats allows the raise the blind appear vain between slats for aeration efficient.

The same way of linking between slats internally set a lock mode to avoid lifting the fraudulent blind from the outside.

Background of the invention

The louvers of known slats allow the air passage when they rise slightly. The air passage is get through the means of linking between slats because these slats are configured according to a link that supports a game between both.

Raising the blind slightly produces a spacing between slats until the bond they maintain makes support for. In this distance a section of the slat is left accessible which allows the bonding that is perforated.

It is important to allow air to pass without raise the blind until it is removed because it still exists a protective barrier and at the same time it is allowed to ventilate the room or space that is protected by the blind.

The need for greater ventilation in the known solutions of the prior art is only possible with larger perforations but the connection must always be maintained between slats since the perforations are in the media of linking between consecutive slats.

The present invention changes the mode of linkage between slats to improve aeration capacity.

Description of the invention

The present invention consists of a blind of slats comprising at least two slats whose connection is established at the ends of each lama. This connection is carried out by middle of a link piece that links them so that, in closed position, the slats are arranged adjacent and in contact closing the space between both slats; and in position open, the link piece establishes a separation distance between slats such that there is a gap between the ends of the the most.

With this solution, the linkage between slats It is located in the area of the guides and the area of the blind cloth where ventilation can occur. The ventilation that is obtained is maximum since the linkage between slats throughout this central area.

Yes it is possible to carry out links reinforcement points when the blade length is high. In In this case, the span generated between slats will be discontinuous.

The different examples of performance result of combining dependent claims 2 to 7 are considered included by reference in this description.

Preferred Embodiment of the Invention

An example of embodiment of the invention where, schematically, show two lateral guides (1) between which the blind.

The blind consists of a plurality of slats (2) that are linked only at the ends by means of a link piece (3).

The first strip (2) is pulling the cloth to keep the slats separated (2). Traction results in a distancing that generates some spans (V) between slats (2) that are those that allow aeration.

The linkage between slats (2) is achieved by the incorporation of an intermediate link piece (3) that is placed at the ends of the slats (2).

Figure 2 shows an example of the piece (3) of link. This link piece (3), in this exemplary embodiment, maintains an articulated joint through a coupling (2.5, 3.1) articulated with the lower slat (2). This same link piece (3), in its upper part it extends like a hook (3.2) stretched from such that it is housed inside a cavity (2.3) of the lama (2) superior.

This cavity (2.3) of the upper blade (2) internally has a projection (2.4) of responsible retention of mutual retention avoiding the exit of the hook (3.2).

The elongated configuration of the section of the cavity (2.3) together with the elongated hook configuration (3.2) It results in a vertical play between both pieces. Before traction, the upper blade (2) is distanced from the lower blade (2) thanks to the distance you need on a hook (3.2) until you reach the projection (2.4) retention.

On the contrary, when closing the blind, the slats (2) consecutive approach because the hook (3.2) of the link piece (3) is housed entirely in the cavity (2.3) of the upper lama (2).

The presence of the link piece (3) makes there is no contact between slats (2) when they are in position of closing. To avoid the presence of grooves in the opening (V) by this minimum distance in the closed position is possible incorporate a weatherstrip (4) located in one of the slats (2), or the  superior or inferior, and that makes contact in the slat (2) adjacent. Figures 3 and 4 are two examples of gasket closure (4). Another possibility is to do without the weatherstrip (4) and make it the configuration of the slat (2) the one that changes along its Length: at the end allows the presence of a piece intermediate, and in the intermediate part the section is longer for allow closure.

Figure 2 shows a special configuration of the link piece (3) and the slats (2) that give rise to a safety interlock to prevent fraudulent rise the shutter pushing up the lower slat (2) instead of applying a traction in the upper blade (2).

This configuration consists of incorporating two Highlights (2.1, 2.2) on the slats (2), a lower highlight (2.1) on the lower area of the slat (2) that is above the piece (3) of link and, a projection (2.2) superior in the superior zone of the plank (2) that is below the link piece (3).

The elevation of the slat (2) lower forces that the link piece (3) is housed internally in the cavity (2.3), at least its hook (3.2). The upper lama (2) supports an inlet (3.3) located at the root of the link piece (3) of such that the relative positioning is fixed. This support together with the joint given by the coupling (2.5, 3.1) articulated results in a turn of the piece (3). This turn projects the lower part of the upper slat (2) against the guide (1) and projects the upper part of the lower slat (2) against the opposite side of the guide (1). The highlights remain in opposition to the plane main cloth blind.

Additionally, the support of the upper plank (2) in the recess (3.3) located at the root of the link piece (3) ensures the relative position between slats (2). This retention mode mutual allows to stabilize the blind and avoid vibrations by example due to wind or fluctuations thereof.

The supports against the guides are produced only in the slats (2) and is carried out through projections (2.1, 2.2) destined to this function producing the interlocking

This same configuration of the section of the intermediate piece (3) it is possible to use it in any connection between slats (2) although they do not require a function of interlocking

In figure 1, and also only as a For example, a specific additional link to through a link piece (3) located in an intermediate zone of the cloth applicable to slats (2) of great length.

Both lamas (2) and weatherstrips (4), They can be manufactured in transparent materials. With this option, the closed blind allows the passage of light.
