Definitions
- the present invention relates to the field of slatted blinds known as “Venetian blinds” for blocking out windows and adjusting the brightness in a room lit by windows.
- These blinds consist of horizontal slats parallel to each other which are oriented by means of cords.
- a Venetian blind allows the light to be obscured and the brightness to be modulated while controlling the possibility of seeing or being seen.
- French patent FR3080643 is known in the state of the art, describing an effective solution for a venetian blind making it possible, depending on its position, to illuminate the interior of the room by reflection of the exterior light on mirrors affixed to the pivoting slats, and of '' hide, depending on the setting, the view towards the interior of the room.
- This patent proposes a Venetian blind made up of slats having an orientable reflecting inner face mounted on a system of cables connected to a control for shifting the cables supporting the front of the slats relative to the cables supporting the rear of the slats, characterized in that said lamellae are orientable, ensuring the reflection of the external zenithal light, the internal transverse edge of said lamellae being extended by an opaque strip with a height of between 0.8 and 1.1 times the interval between projection, on the rear plane of the blind, from the front edge of the slat carrying said opaque strip, and the rear edge of the adjacent lower slat.
- Japanese patent application JP2011179225 describes another example aimed at letting sunlight, the height of which varies according to the season, to pass through an agricultural greenhouse.
- the blind is made of flat wooden slats with a reflection film bonded to the top surface of the slat. Sunlight is transmitted into the greenhouse by adjusting the angle of each slat.
- the present invention relates in its most general sense to a venetian blind consisting of a plurality of slats each having a reflecting upper face, said slats being orientable by pivoting between a position where the normal to the reflecting surface is oriented vertically upwards, and positions where said normal to the reflecting surface is oriented inwards, characterized in that each of said lamellae being extended at its edge exterior by a strip extending downwards, said strip having a width at least equal to the height separating two consecutive strips, the lower edge of each of said strips being rigid and connected to an interior vertical connection means.
- the term “reflecting surface” means an opaque surface producing a specular reflection in the visible spectrum in a single direction of reflection, or in a single reflection beam having an opening angle of less than 20 °.
- the aperture angle of the reflection beam is measured from the middle direction where the reflection produces its maximum light intensity (the center) to the direction where the light source still gives 50% light. In the latter case, the light is reflected to produce a soft light that is less dazzling than in the case of strictly specular reflection while concentrating most of the incident energy reflected in the direction of the part.
- a painted or varnished surface will not be considered reflective within the meaning of this patent, even when the coating is glossy.
- the inner edge of the bands is de facto rigid when the bands are made of a rigid material. Failing that, if the bands are flexible, their edge is completed by a rigid longitudinal rod, for example a rod sliding in a hem formed at the edge of the band.
- said interior vertical connecting means also connects the interior edges of said lamellae.
- said internal connecting means is a guided cord, in particular guided vertically.
- said strip is a flexible strip.
- said strip is a rigid strip.
- said strip is an opaque strip: when the slats are in a vertical position, the blind is completely blackout.
- said strip is a translucent strip: when the slats are in a horizontal position, the blind lets diffused light through but preserves privacy.
- said strip is a transparent strip.
- the outer edges and / or the inner edges of two consecutive lamellae are articulated by at least one rigid connection. Seen from the side, the lamellae and the links then form a deformable parallelogram formed by two consecutive lamellae and the links connecting the consecutive inner edges and consecutive outer edges.
- the outer edges and / or the inner edges of said strips are articulated by at least one flexible connection.
- the width of said slats corresponds to the distance separating two consecutive slats.
- FIG. 1 shows a schematic sectional view of a window equipped with a blind according to the invention in a first orientation
- FIG. 2 shows a schematic sectional view of a window equipped with a blind according to the invention in a second orientation.
- - Figure 3 shows a schematic sectional view of an alternative embodiment of a window equipped with a blind according to the invention in a second orientation.
- Figures 1 and 2 show an example of a window consisting of a frame (1) provided with a transparent glazing (2).
- the blind consists of slats (10 to 14) supported by cords (45, 46).
- Each slat has a reflective upper surface (5) reflecting sunlight towards the interior of the room.
- the aim is to provide visibility of the sky from a room, even when direct vision does not allow it.
- each strip (10 to 14) is extended by a strip (30 to 33), for example made of fabric.
- These flexible bands (30 to 33) fall vertically to obscure direct vision, and protect privacy, while approaching the inner edge of the lower slat, allowing sunlight to penetrate.
- these bands (30 to 33) can consist of rigid hinged strips to allow tilting relative to the outer edge (20 to 24) of the strip (10 to 14) which they extend.
- These bands prevent vision into the room from outside, from a point of view at the same level as the opening.
- the view is masked on the one hand by the opaque and shimmering slats alternating with these opaque bands.
- the slats (10 to 14) provided with a mirror are adjustable by a system consisting of a first wire stretched (45) on the side of the window and a second wire (46) on the part side.
- Each strip (10 to 14) has transverse rods at its outer ends (towards the window).
- each rod is fixed a flexible strip (30 to 33) to which is fixed a second rod transverse to its second end.
- This second rod should be heavy enough so that it can slide along the inner wire.
- the window side rods are fixed at predetermined heights, with a constant pitch, on the first wire (45), with a degree of freedom in pivoting.
- the outer rod can also be attached to the mirror independently of the wire.
- the rods on the part side are positioned in front of (towards the part) the wire (46).
- the strips (20, 21) are connected to the outer (45) and inner (46) threads by beads (50, 60;
- FIG. 3 represents a view of an alternative embodiment.
- the strip (30) is fixed on the one hand on the outer transverse edge of the upper strip (20), and on the other hand on a rigid rod (36) driven by a third wire (56), arranged vertically and can be pulled up or down to change the orientation of the web (30).
