Definitions

  • the invention is related to a louvre system for a ventilator, comprising a series of parallel louvre units each with at least one louvre and at least one support which is integral with a louvre, the louvres being at a distance from each other and enclosing ventilation gaps, as well as support members by means of which the louvre units are supported, wherein the louvre units each have at least one mounting part, the support members have support parts and each mounting part of a louvre unit is mounted onto a support part of the support members.
  • Such a louvre system is disclosed in US-A-3451180 .
  • Said prior art louvre system has louvre units which, at the upper end as well as at the lower end thereof, are each directly connected to a support member.
  • the louvre units are at a distance from each other and enclose ventilation gaps between them.
  • a further louvre system is disclosed in British patent application 2.126.707 .
  • Said prior art publication comprises parallel louvre blades which are inclined to the vertical. Moreover, there is a horizontal guard mesh located between said blades. Each louvre blade is attached separately to the support members through respective holders. The guards and each provided with a plurality of apertures, for permitting an air flow.
  • the louvre system in question is intended to be mounted in front of the ventilation opening of the building.
  • first of all the support members have to be mounted on to the building.
  • said support members have to be equipped with a series of holders.
  • each louvre blade is attached separately to a row of holders next to each other on neighbouring support members.
  • the disadvantage of such a layout is that the process of assembling the great number of different parts is time-consuming and cumbersome.
  • the costs of the louvre system according to said prior art document and therefore too high, in particular as a result of the fairly large amount of labour costs.
  • a louvre system which comprises the frame into which the louvre units are stacked upon each other.
  • the disadvantage of this prior art louvre system is that the length dimension of the louvres cannot be very large. This caused by the fact that the louvres are only supported at the opposite ends, but not at locations in between said ends.
  • the object of the invention is to provide a louvre system having a less complicated mounting of the louvre units onto the support members and which is more versatile.
  • This object is achieved in that each louvre unit is carried out as a single profile, and in that a support has a free end provided with connecting means, the opposite side of the louvre unit having counter connecting means, in such a way that the connecting means and the free end of a support of one louvre unit are connected to the counter connecting means of neighbouring louvre unit.
  • the louvre units according to the invention are not only connected to the support members but are also mutually connected.
  • louvre a units each comprise at least two neighbouring louvres and an intermediate member by means of which the louvres are permanently interconnected.
  • louvre units which each comprise two or even more preassembled or permanently attached louvre blades has the advantage that in the process of assembling the louvres system even less separate components have to be dealt with. In fact, complete arrays of two or more louvre blades can be mounted in one time to the support members, thus reducing the labour time and labour costs involved drastically. Moreover, the louvres system is obtained has a very high strength and rigidity, as a result of the interconnection between neighbouring louvre blades.
  • connection between the louvre units and the support members can be obtained in different ways.
  • the mounting parts and the support parts may comprise hooks.
  • said mounting parts and the support parts may comprise undercut cavities.
  • a very easy way of assembling of the louvre system is obtained in case the mounting parts and the support parts are carried out as click means allowing elastic deformation during the process of mounting. By pressing the louvre units onto the support members, a certain elastic deformation of the mounting means is obtained and the final connection is established as soon as the louvre units and support members produce a click.
  • the support members each may have a flange which is oriented transversely with respect to the plane as defined by the louvres, the support parts being arranged on the flange.
  • the support parts may be carried out as undercut cavities which open out at the free edge of the flange.
  • the louvres have a free end and a mounting end, said mounting end being provided with a mounting part.
  • the mounting end of the louvres may be carried out as a hook. As mentioned before, said hooks of the louvres can be clicked into the corresponding undercut cavities.
  • the louvre units themselves can be carried out in various ways as well.
  • the louvre unit may comprise a single louvre and a single support integrally or permanently connected thereto.
  • the louvre unit may comprise two neighbouring louvres and an intermediate support, by means of which intermediate support the louvres are permanently or integrally interconnected.
  • Such louvre unit which comprises two neighbouring louvres and an intermediate support may comprise two hooks which face away from each other or which face each other.
  • the louvre unit with at least two louvres has a further support which is permanently or integrally connected to one of the louvres at the side thereof facing away from the connecting support, said further support having a free edge provided with connecting means.
  • the supports of the louvre units louvre units can be carried out in several ways as well.
  • the support can be carried out as a web provided with ventilation openings.
  • the louvre blade(s) and the web can be carried out as a single profile, for instance a profile obtained by means of extrusion.
  • the louvre blade(s) and the intermediate member such as a web can be permanently connected to each other by means of welding, soldering, gluing et cetera.
  • the openings in the web provided the required ventilation.
  • These openings can be carried out in different ways as well.
  • the ventilation openings are of a longitudinal shape, the longitudinal direction of said openings being oriented transverse with respect to the longitudinal direction of the louvres.
  • the ventilation openings can be of a square shape. Any desired shaped shape provides the required ventilation capacity is of course possible.
  • the orientation of the support web can be selected in different ways as well.
  • the web in a louvre system wherein the louvres each have a free end and a connection end which is supported with respect to the support members, the web extends between the parts of the louvres next to or at the connection ends thereof.
  • the invention is furthermore related to a method for manufacturing a louvre unit for use in the louvre system as described before. Said method comprises the steps of:
  • Such process can be applied for obtaining a louvre unit having two louvres and an interconnecting web as well.
  • the holes in the web can be obtained by means of punching.
  • the louvre system as shown in figure 1 comprises mounting profiles 1, which have to be mounted on a wall over a ventilation opening therein.
  • Said mounting profiles 1 consist of a base plate 2 and a flange 3 provided with regularly spaced undercut cavities 4. It will be clear that several of these mounting profiles 1 are arranged next to each other at regular intervals, the number of mounting profiles 1 depending on the length of the louvre units 5 described below and the required stability of the louvre system.
  • the louvre system consist of louvre units 5, which are shown in disassembled state in figure 2 and 3 .
  • the louvre units 5 according to figure 2 each consist of two louvres 6, interconnected by means of an intermediate web 7.
  • the louvre unit according to figure 3 comprises a single louvre 6 and a single web 7.
  • Each web 7 may have a series of longitudinal openings 8, or square openings 9, or a combination thereof. Of course, any type of opening will do provided the required ventilation capacity is obtained.
  • Each louvre unit 5 which has two louvres 6 is provided with two connecting hooks 10, which are hooked in the undercut cavities 4. These connecting hooks 10 are provided at the connecting end of each louvre 6. Furthermore, the upper edge of each louvre unit 5 is provided with an upwardly extending lip 12; the free end of the lowermost web 7 is provided with the downwardly extending U-shaped cavity 13. The upwardly extending lip 12 is accommodated within said downwardly extending U-shaped cavity 13, whereby a firm interconnection of the neighbouring louvre units 5 is obtained.
  • single louvre units 15 may be provided, which consist of a single louvre 6 and a single web 7. These louvre units 15 are provided with an upwardly extending lip 12 and a downwardly extending U-shaped cavity 13 as well.
