EP2813631B1 - Dimming system with adjustable blade for solar protection installation - Google Patents

Description

The present invention relates to a solar protection installation incorporating several occultation systems.

The invention lies in the field of sun protection systems with steerable blades forming a protective roof opening and closing, in particular of the type with adjustable blades.

Such installations typically include a structure consisting of posts that support upper or upper beams. On these beams are articulated steerable blades which are articulated at their respective ends on two opposite and parallel beams - said blades thus extending perpendicular to these two support beams. Conventionally, a drive system, motorized or manual, cooperates with the blades to rotate concomitantly or simultaneously between a closed position in which the blades are substantially contiguous to close the roof and an open position in which the blades are separated from each other to open the roof.

Such installations are notably known from the documents EP 2 589 720 A1 and FR 2 947 845 A1 , in which the blades are each in the form of a profile having two longitudinal orifices opening on both ends of the blade. Hinge pins are mounted on both ends of one of the orifices so that the blade pivots about these two axes. A linkage axis of the drive system is mounted on one end of the other port so that the drive system can rotate the blade about the two aforementioned hinge pins.

It is also known from the document WO 95/12738 an installation in which each blade is in the form of a profile having a first longitudinal opening opening on both ends of the blade, a second longitudinal opening opening on both ends of the blade and a third longitudinal orifice, where the first orifice is located above the second orifice in a situation in which the blade is laid flat on a horizontal plane. For each blade, hinge pins are mounted on both ends of one of the orifices (the first orifice or the second orifice) so that the blade pivots about these two axes.

In the aforementioned three prior arts, since the two axes of joints are mounted in the same longitudinal hole, the two axes are perfectly aligned longitudinally. So when one goes up the installation on a flat and horizontal support (ground, terrace, etc.) and that one uses identical posts, and therefore of the same height, one obtains horizontal beams and located at the same height (in other words the beams define a horizontal plane), so that the blades articulated on these beams with their respective hinge axes are also horizontal.

However, such a horizontality of the blades can be problematic for the evacuation of rainwater when the roof is closed, because the water accumulates on the blades, in particular when means of collecting water are provided thereon , and may overflow over the blades rather than being evacuated towards ditches provided on the beams for the flow of water.

To remedy this problem, the installers of such installations provide a slope for the blades by acting on the structure, for example by using wedges or using posts of different heights. Thus, they obtain an installation with blades inclined relative to the horizontal in the direction of the length, that is to say with a first end located higher than the opposite second end. Thus, the rainwater can flow naturally towards the second lower end, the second end being articulated on a beam generally accommodating a drainage channel.

However, this solution is inconvenient for installers who must work on the structure to obtain such a slope, even if it is necessary to shorten poles when they are all identical. This problem proves even more embarrassing for private, non-professional, who provide with such facilities to build yourself as a kit.

Another solution is known from the document EP 1707729 A1 .

The present invention aims to solve the problem of steerable slats slope in a solar protection installation, providing a simple and economical solution that does not require complex handling for installers.

For this purpose, it proposes a protection installation according to claim 1.

It is understood, for the remainder of the description, that the notions of "high" or "superior" and "low" or "lower" are understood in relation to a situation in which the blade is laid flat on a plane horizontal, in other words, when its longitudinal main axis is horizontal. In this situation, a first member is located above a second member when it is higher than the second member in a vertical direction perpendicular to the horizontal plane; in other words, the first member is further away vertically from the horizontal plane than the second member. Conversely, a first member is located below a second member when it is lower than the second member in the same vertical direction.

Thus, thanks to the invention, the two axes of articulation of the blade, defined respectively by the two anchoring members (and therefore by the two articulation members mounted on these anchoring members), are not aligned. longitudinally, and are offset relative to each other vertically. In this way, the blade is articulated at its first end to the first beam along the first hinge axis defined by the first anchoring member (and also by the first hinge member), while the blade is articulated to its second end on the second beam along the second axis of articulation defined by the second anchoring member (and also by the second articulation member). Thus, when a structure is used with horizontal transverse beams situated at the same height with respect to a horizontal support, the two axes of articulation of the blade are situated at the same height with respect to the horizontal support, so that the blade necessarily has a slope relative to the horizontal support, directed from top to bottom of the second towards the first end.

In this way, the invention makes it possible to create a slope for the blades while maintaining horizontal transverse beams of the same length and thus located at the same height relative to the horizontal support, creating an offset at the two axes of articulation. on the opposite ends of the blades. It is this gap between the two axes of articulation (in other words between the two anchoring members) that will naturally create the desired slope.

Advantageously, each end is provided with first, second and third anchoring members, wherein the first anchoring member is located above the second anchor member at each end.

• monter le premier organe d'articulation dans le premier organe d'ancrage de la première extrémité de la lame et le second organe d'articulation dans le second organe d'ancrage de la seconde extrémité de la lame, créant ainsi un décalage entre les deux axes d'articulation dans un sens ;
• monter le premier organe d'articulation dans le second organe d'ancrage de la première extrémité de la lame et le second organe d'articulation dans le premier organe d'ancrage de la seconde extrémité de la lame, créant ainsi un décalage entre les deux axes d'articulation dans un sens opposé ;
• monter le premier organe d'articulation dans le premier (respectivement second) organe d'ancrage de la première extrémité de la lame et le second organe d'articulation dans le premier (respectivement second) organe d'ancrage de la seconde extrémité de la lame, créant ainsi un alignement entre les deux axes d'articulation.

Thus, the blade has a symmetry between the two ends, so that one can:

• mounting the first hinge member in the first anchor member of the first end of the blade and the second hinge member in the second anchor member of the second end of the blade, thereby creating a gap between the two articulation axes in one direction;
• mounting the first hinge member in the second anchor member of the first end of the blade and the second hinge member in the first anchor member of the second end of the blade, thereby creating a gap between the two axes of articulation in an opposite direction;
• mounting the first hinge member in the first (respectively second) anchoring member of the first end of the blade and the second hinge member in the first (respectively second) anchoring member of the second end of the blade , thus creating an alignment between the two axes of articulation.

According to one feature, the blade is constituted by a profile of continuous cross-section, with first and second longitudinal orifices parallel to the longitudinal main axis and extending over the entire length of the blade, where the first orifice s' extends above the second orifice, and wherein the first orifice opens on each end of the blade to form the first anchoring members and the second orifice opens on each end of the blade to form the second anchoring members.

In this way, the anchoring members consist of holes opening on the ends, and it is sufficient to mount the hinge members at both ends of the blade in the two orifices of its choice, depending on the direction of the desired slope .

In one particular embodiment, the blade has first and second opposite longitudinal edges, an upper stormwater flume extending along the first longitudinal edge and a lower flushing spring extending along the second longitudinal edge. longitudinal edge and below the upper wing, where the first anchor member is located closer to the upper wing than the lower wing while the second anchor is located closer to the lower wing than the upper wing.

In this configuration, the two longitudinal edges are preferably substantially the same level (always in a situation where the blade is laid flat on a horizontal plane) so that, in an installation, the first longitudinal edge of a blade is substantially joined with the second longitudinal edge of an adjacent blade in the closed position of the roof. Thus, in this closed position of the roof, the rainwater flows on the upper wing of the blade towards the lower wing of the adjacent blade. In other words, it is preferable that the upper blade is in the form of an inclined face relative to the lower wing and has a downward slope towards the first longitudinal edge.

Advantageously, the blade has a central core (for example vertical) extended on one side and in the upper part by the upper wing and extended on an opposite side and in the lower part by the lower wing, and where the first hole is located at the junction between the upper wing and the central core and the second port is located at the junction between the lower wing and the central core.

This location of the orifices at the junction between the central core and the two wings ensure improved mechanical strength and easy manufacture of the blade.

In a particular embodiment, the blade has a third longitudinal orifice parallel to the longitudinal main axis and extending over the entire length of the blade, where the third orifice opens on each end of the blade to form the third members of the blade. anchor. According to a possibility of the invention, the third longitudinal orifice is located on the upper wing, and preferably on a lower face of this upper wing.

Advantageously, the first and second articulation members each comprise a first element mounted on the corresponding anchoring member and a second element of the ball-and-socket type intended to form a ball joint on the corresponding beam.

Indeed, such ball joints can reduce the constraints associated with mounting with the two axes of articulation at the respective ends of the blade which are not aligned.

According to the invention, this system also comprises a third articulation member mounted on the third anchoring member at one of the ends of the blade, and this third articulation member is preferably of the type comprising a first element. mounted on the third anchor member and a second element of the ball joint type.

According to one characteristic, the transverse beams are horizontal and are located at the same height relative to a support horizontal, so that the hinge members of the blades are located at the same height relative to the horizontal support and the blade has a slope relative to the horizontal support, directed from top to bottom of its second to its first end.

With reference to the figure 7 , a blade 2 is composed of a profile made of a rigid material, which has a continuous cross section and which extends along a main longitudinal axis A.

For the following description of the blade 2, it is assumed that the blade 2 is placed on a horizontal plane with its longitudinal principal axis A parallel to this horizontal plane, for the definitions of the terms "top" or "upper" and "lower". And "inferior".

This blade 2 has a central core 20 consisting of a vertical wall which is extended on one side (left on the figure 7 ) and upper or upper part by an upper wing 21, and which is extended on an opposite side (right on the figure 7 ) and in the lower part by a lower wing 22.

The blade 2 has first and second longitudinal edges 23, 24 opposite, with the upper wing 21 extending along the first edge 23 and the lower flange 22 which extends along the second longitudinal edge 24.

The lower flange 22 is a rainwater collection flange and extends horizontally, perpendicular to the central core 20. This lower flange 22 is located below the upper flange 21, and ends with the second longitudinal edge 24 which forms a vertical rim oriented upwards. The lower flange 22 also continues below the lower flange 21 and ends with a return 25 fixed on the upper flange 21, this return 25 being set back with respect to the first longitudinal edge 23.

The blade 2 has a first 26 and a second 27 opposite ends, these two ends 26, 27 being provided to be articulated on transverse beams 51, 52 (described below) of the supporting structure of the installation 1.

The first orifice 31 is located at the junction between the upper flange 21 and the central core 20, on the side of the lower face of the upper flange 21 (that vis-à-vis the lower flange 22, to the opposite of the upper face which is exposed to bad weather). This first orifice 31 is thus defined by the upper flange 21, the central core 20 and an arcuate wall disposed in the corner. The first orifice 31 constitutes an anchoring member designed to receive a first articulation member 41 (described below) on the first end 26 of the blade 2. Thus, the first orifice 31 defines a longitudinal axis of articulation or pivoting the first end 26.

The second orifice 32 is located at the junction between the lower flange 22 and the central core 20, on the side of the lower face of the lower flange 22 and vis-à-vis the first orifice 31. This second orifice 32 is thus delimited by the lower flange 22, the central core 20 and an arcuate wall disposed in the corner. The first and second orifices 31, 32 are arranged vertically one above the other. The second orifice 32 constitutes an anchoring member designed to accommodate a second articulation member 42 (described below) on the second end 27 of the blade 2. Thus, the second orifice 32 defines a longitudinal axis of articulation or pivoting of the second end 27.

The third orifice 33 is located on the lower face of the upper flange 21, substantially in the middle thereof. The third orifice 33 constitutes an anchoring member designed to receive a third articulation member 43 (described below) on the second end 27 of the blade 2; this third articulation member 43 being provided to cooperate with a drive system 6 (described below).

Taking as reference the lower flange 22, the first port 31 is located at a height H1, the second port 32 at a height H2 and the third port 33 at a height H3, where H2 <H3 <H1. The first orifice 31 is thus located above the second orifice 32 of an offset height HD, where HD = H1 - H2. The three orifices 31, 32, 33 are of the same size.

The second element is in the form of a substantially spherical ball joint, provided to form a ball joint with three degrees of freedom in rotation.

The installation 1 also comprises a supporting structure 5 comprising at least two beams 51, 52 transverse, parallel to each other and spaced from each other by a spacing slightly greater than the length L of the blades 2. These beams 51, 52 are made in the form of profiles. For the rest of the description, it is assumed that the beams 51, 52 are horizontal and situated at the same height with respect to a horizontal plane (X, Y), X and Y defining two horizontal axes with the beams 51, 52 parallel to the Y axis.

• la rotule du premier organe d'articulation 41 est montée dans une cavité sphérique prévue sur une pièce de jonction 53 (formant palier) fixée sur la première poutre 51, assurant ainsi une liaison rotule de la première extrémité 26 de la lame 2 sur la première poutre 51 pour un pivotement selon un premier axe d'articulation passant par le premier orifice 31 ;

The installation 1 comprises several blades 2 parallel and articulated on the beams 51, 52 by means of their respective first and second articulation members 41, 42. More precisely, for each blade 2:

• the ball of the first articulation member 41 is mounted in a spherical cavity provided on a connecting piece 53 (forming a bearing) fixed on the first beam 51, thus ensuring a ball joint connection of the first end 26 of the blade 2 on the first beam 51 for pivoting along a first axis of articulation passing through the first orifice 31;
• the ball 44 of the second articulation member 42 is mounted in a spherical cavity provided on a connecting piece 53 (forming a bearing) fixed on the second beam 52, thus ensuring a ball joint connection of the second end 27 of the blade 2 on the second beam 52 for pivoting along a second axis of articulation passing through the second orifice 32.

• une position fermée (visible sur les figures 1, 3, 5 et 6) dans laquelle les lames 2 sont sensiblement jointives pour fermer le toit, avec le premier bord longitudinal 23 d'une lame 2 qui vient chapeauter et recouvrir le second bord longitudinal d'une lame 2 adjacente ; et

The installation 1 also comprises a drive system 6 incorporating a jack 60 (hydraulic, pneumatic, or electric) which is pivotally mounted on the second beam 52 (see figure 5 ) and which actuates a rod 61 which ensures the simultaneous pivoting of the blades 2 by means of a linkage system comprising a connecting rod 62 on which are mounted the ball joints of the third hinge members 43. Thus, the drive system 6 makes pivot the blades 2 concomitantly between:

• a closed position (visible on figures 1 , 3 , 5 and 6 ) in which the blades 2 are substantially contiguous to close the roof, with the first longitudinal edge 23 of a blade 2 which comes to cap and cover the second longitudinal edge of an adjacent blade 2; and

Due to the shift of an offset height HD between the first and second orifices 31, 32, the longitudinal main axis A of the blade 2 has an angle AN with respect to the horizontal axis X which corresponds to the following relation: $$\tan \left(\mathrm{YEAR}\right)=\mathrm{HD}/\mathrm{The}\mathrm{AN}={\tan }^{-1}\left(\mathrm{HD}/\mathrm{The}\right)$$

with for recall L the length of the blade 2.

Thus, the blades 2 have a slope with the angle AN defined above relative to the horizontal, allowing a flow of rainwater towards their second ends 27.
