Description

DESCRIPTION

EXTERIOR VENETIAN BLIND

OBJECT OF THE INVENTION

The present invention refers to an outdoor Venetian blind, which allows to occlude or cover the entry of external light better than the existing ones, in addition to achieving a rotation from the axis located at the upper end of the slats instead of the center of the slats. .

BACKGROUND OF THE INVENTION

Venetian blinds are known, also called stackable blinds, which comprise a lower crossbar attached to lifting belts or textbands (two generally), and a plurality of intermediate slats provided with vertically aligned holes for the lifting belts to pass through. , and related to an internal inclination chord and an external inclination chord, normally by means of lower stirrups that join both belts and run under the slats, which rest on these and whose slats incline when the stirrups are inclined, as their height shifts the Inner tilt chord relative to the outer tilt chord.

The through holes of the lifting belts are arranged in the medial axes of the slats, comprising a head profile, or head, provided with means of fixing to the ceiling or frame of a building opening (window, door or similar), and in which some first reels or first deflections of the lifting belts are mounted to raise the lower cross member and fold the blind above, and a few second reels or second deflections to offset the height of the rear tilt cord with respect to the front tilt cord and tilt the stirrups, which causes the intermediate slats to tilt around their medial axis, and serves to regulate the entry of light, which will be greater by aligning the slats with the direction of the sun, and less otherwise.

The problem with these blinds is that they do not get completely opaque, That is, they cannot completely flatten one slat over another to configure a completely opaque surface to the entry of exterior light, which enters through the sides of the slats and through the holes that the slats have for the passage of the lifting belts, for What is required is the provision of additional blinds in the gaps to protect if it is necessary to completely cover the entrance of light.

DESCRIPTION OF THE INVENTION

The external venetian blind of the invention is of the type comprising a lower crossbar attached to lifting tapes or textbands and a plurality of intermediate slats provided with holes - vertically aligned - for the passage of the lifting tapes, and related to a cord. inner slope and an outer slope cord; and comprising a head provided with fixing means to the ceiling or doorway of a building opening and in which are mounted first reels or first deflections of the lifting belts to raise the blind, and second reels or second deflections of the Tilt chords, to offset the height of the rear tilt chord with respect to the front tilt chord and tilt the slats. These reels can be a single piece or reel, which first tilts and then raises or lowers the slats depending on the direction of rotation.

According to the invention, in addition, the blind:

-comprises lateral guides arranged on both sides near the inner edge of the slats, the slats comprising pivots on both sides at their inner end and the lower cross member comprising guides, said pivots and said guides being inserted in said lateral guides to run along them when raising and lowering the blind,

-the holes for the passage of the lifting belts are also arranged in the vicinity of the inner edge of the slats, said lifting belts running through them,

-the inner tilt cord is attached to the inner edge of each slat and the outer tilt cord is attached to the outer edge of each slat, and

-where the slats have an amplitude equal to or greater than the vertical distance between the axis of rotation defined by their lateral pivots and the holes in the immediately lower slat.

In this way, what is achieved is to fold the intermediate slats around their inner edge, since the slat folding axis is located practically on the inner edge of the slats, and they can be folded down completely, remaining vertical, thereby This is achieved that they completely overlap on the lower slat and cover their holes for the lifting belts, materializing a perfect darkening, and also thinning the horizontal volume occupied by the slats, as they are completely vertical.

PREFERRED EMBODIMENT OF THE INVENTION

The external Venetian blind (1) of the invention is of the type that comprises a lower crossbar (2) attached to lifting belts (3), and a plurality of intermediate slats (6) provided with holes (7) (see enlargement of details in Figures 1 and 2) of the passage of the lifting belts (3), and related to an internal inclination cord (4) and an external inclination cord (5); and comprising a head (8) provided with fixing means to the ceiling or doorway of a building opening and in which are mounted (see figs. 3 to 5) some first reels or first deflections (9) of the lifting belts (3), and second reels or second deflections (10) of the inclination cords (4, 5) to offset the height of the rear inclination cord (4) with respect to the front inclination cord (5); that according to the invention:

-comprises lateral guides (12) arranged on both sides near the inner edge (61) of the slats (6) (see figs. 1 and 2), the slats (6) comprising pivots (15) on both sides At its inner end and the lower cross member (2) some guides (20) (see in figs. 3 to 5), being said pivots (15) and said guides (20) inserted in said lateral guides (12) to run along along them when raising and lowering the blind,

-the holes (7) for the passage of the lifting belts (3) are also arranged near the inner edge (61) of the slats (6), said lifting belts (3) running through them (see enlargement of the details of figs. 1 and 2),

-the inner inclination cord (4) is attached to the inner edge (61) of each slat (6) and the outer inclination cord (5) is attached to the outer edge (62) of each slat (6), by means of some staples, not shown, and

- where the slats (6) have an amplitude equal to or greater than the vertical distance between the axis of rotation (15a) defined by its lateral pivots (15) and the holes (7) of the immediately lower slat. (see in fig. 3).

In the preferred example of the invention shown in the figures, the lower cross member (2) comprises a front extension (23), projecting under the slats (6), and the guides (20) are anti-rotating (that is, they do not allow the rotation of said crossbar, but only its vertical conduction) so that the front extension (23) of the crossbar maintains horizontality along the vertical guide. This allows the provision of a seal (22) (felt brush or mat) under the front extension (23) to seal the passage of light below and cover small inclinations of the windowsills of the building holes. In the embodiment of the figures, the lower cross member (2) also comprises a blind vertical rear portion (21) (see in figs. 1, 2 and 4), the ends of which are inserted in the lateral guides (12), configuring the guides. (20) anti-rotation, whereby the last intermediate slat, when resting against said rear blind vertical portion (21), also perfectly closes the passage of light in this area, as seen in fig. 1 and 3, also assuming possible imperfections or irregularities in the hole where the external Venetian blind will be located.

Additionally, the provision of some side profiles (14) (see in fig. 5) provided with flaps (13) directed towards the heart of the blind on the inside of it, to cover the entry of light through the sides of slats (6) and lower cross member (2), the lateral guides (12) being ideally integrated in these lateral profiles (14) as seen in the details of fig. 5, with the consequent cost savings by putting two functionalities in a single piece. In addition, the side profiles (14) can be coupled to the head (8), configuring a pre-assembled, lower open frame to facilitate insertion in the construction hole.

Finally, it should be noted that the slats (6) preferably comprise a broken cross section (see in detail in fig. 2) with two long sections (66a, 66b) that are substantially longitudinal alternated with two short sections (67a, 67b) that are substantially transverse, the outer edge (62) of each slat (6) arranged in the long outer end section (66a) and the pivots (15) of the slat (6) in the short inner end section (67b), specifically in the center of said section ; the holes (7) being arranged for the passage of the lifting belts (3) on the edge (68) (see detail enlargement of fig. 2) defined between the short inner end section (67b) and the long inner section ( 66b). In this way, the difference in position between the two long sections (66a, 66b) allows the upper part of the immediately lower slat to be accommodated, as seen in fig. 1, giving the shutter with the slats closed an aspect of continuity and better resistance to wind.

Having sufficiently described the nature of the invention, it is indicated that the description of the invention and its preferred embodiment should be interpreted in a non-limiting manner, and that it encompasses all of the possible embodiment variants that may be deduced from the content of this report. and claims.
