Abstract
Description
- The invention relates to a façade slat comprising two main walls of a dense plate which during use are vertically oriented and are each provided with a lower edge, an upper edge and a first and second side edge, which main walls are connected to each other at the first side edge.
- Such a façade slat is known from
NL1031193A - An object of the invention is to improve the known façade slat such that it has a better effect and keeps a door opening substantially free from undesired draft phenomena. To this end, the façade slat according to the invention is characterized in that the second side edges of the main walls are present at a greater distance from each other than the first side edges and between these second side edges a side wall is present formed by wind-leveling mesh. Wind-leveling mesh is here understood to mean mesh with such small grid openings that the wind passing through is slowed down. The façade slat according to the invention is attached to a façade with the first edges next to a door opening. Due to this façade slat, a wind flowing along the façade is guided off the façade by the hollow main wall, whereby the wind is guided through the side wall into the space between the two main walls, thereby preventing annoying air flows at the door opening. Because the wind disappears through the side wall into the façade slat, the pressure on both sides of the façade slat is balanced so that there is no wind demand at the entrance door. The consequence of this is that an entrance door is kept wind-free. Research has shown that placing façade slats according to the invention has a positive effect on the performance of an air curtain in the doorway. Where the air curtain ensures the heating of the air that penetrates, the façade slat ensures that the wind does not disturb the operation of the air curtain. This reduces the heating requirement of the building.
- To effectively guide air into the space between the main walls, the side wall in horizontal cross-section preferably has a curved shape, the convex side of which is directed outwards.
- The façade slat preferably has the shape of a wing profile with two curved main walls, the outward facing side of one of the main walls being convex and the other main wall being hollow.
- The façade slat is provided on the first side edges of the main walls with fixing means for attaching the façade slat to a facade. These fastening means preferably comprise a hinge so that the façade slat can be mounted rotatably on a façade and can be turned in a desired angle relative to the facade, depending on the wind direction.
- In order to get the air flowing in the space between the main walls out of the façade slat with minimal resistance, the top and bottom of the façade slat are open.
- For the sake of the stability and sturdiness of the façade slat, transverse links are preferably present between the main walls in the vertical direction at a distance from one another, for example in the form of plates provided with recesses.
- The invention will be further elucidated below on the basis of drawings. These drawings show an embodiment of the façade slat according to the present invention. In the drawings:
-
Figure 1 shows an embodiment of the façade slat according to the invention; -
Figure 2 shows the façade slat infigure 1 in top view; -
Figure 3 the façade slat fixed next to a door opening on a façade; and -
Figure 4 shows a door opening with a façade slat on either side in top view. -
Figures 1 and2 show an embodiment of the façade slat according to the invention in perspective and top view, respectively. Thefaçade slat 1 has two vertically oriented windproofmain walls lower edge 7, an upper edge 9 and a first andsecond side edge first side edge 11. Thesecond side edges 13 of the main walls are spaced apart and between these side edges there is acurved side wall 15 with an air-flow permeable structure formed by a wind-leveling mesh. The convex side of theside wall 15 is oriented outwards. In horizontal cross-section (seefigure 2 ), thefaçade slat 1 has the shape of a wing profile. The outward facing side of the firstmain wall 3 being hollow and that of the secondmain wall 5 is convex. Thetop side 17 and the bottom side 19 of thefaçade slat 1 are open to allow the air, that has flown through theside wall 15 into thespace 21 between the main walls, to flow out of this space. In thespace 21 between the main walls there are reinforcingplates 23 provided with continuous recesses, these plates form transverse connections. - On the
first side edges 11 of themain walls façade slat 1 is provided with fixing means for fixing to a facade. These fixing means are formed by ahinge 25 and afixing strip 27. Infigures 3 and 4 , thefaçade slat 1 is attached to afaçade 31 next to a door opening 33, shown in perspective and top view, respectively. By means of thehinge 25, the angle of the façade slat 1 with respect to thewall 31 and with respect to the wind direction can easily be adjusted to optimally deflect the wind so that it does not cause any unwanted air movements in the door opening. - Although the present invention is elucidated above on the basis of the given drawings, it should be noted that this invention is not limited whatsoever to the embodiments shown in the drawings. The invention also extends to all embodiments deviating from the embodiments shown in the drawings within the scope of the invention defined by the appended claims.
