Definitions

  • the present invention relates to a louver specifically conceived as an air deflector for use in air conditioning diffusers, specifically as a swivelling deflector.
  • a diffuser of this type appears in the invention Patent ES 2,110,136 (family member of the European patent EP-A-0616178 ) in which established on each diffuser opening are two parallel lids or supports coupled to said opening by a bayonet system, between which laminar supports is established a shaft about which revolves the deflection louver, embodied in a hollow profile with an inner groove for coupling said shaft.
  • louver disclosed by the invention solves the aforementioned problem in a fully satisfactory manner, as regards the various issues discussed.
  • its shaft is fragmented into two short end segments that emerge and are joined to the corresponding supports or plates, which as the latter and the louver itself are made of plastic, so that their installation is faster and easier, without any expansion problems as all components are made of the same material.
  • the aforementioned shafts are also provided with ribs in their longitudinal sense that improve their grip inside the hollow space of the louver itself.
  • the operative face of the louver itself is, that facing the air outlet opening, has a curved-convex shape with a curvature that maintains a constant air flow and outlet resistance regardless of the position of said louver.
  • the end laminar supports made of plastic as stated before, incorporate a flat and intermediate chamber open on the side by which it is coupled to the base plate, inside which runs a metal sheet with its free and outwardly emergent edge having an orthogonal elbow that greatly improves the attachment of the louver as a whole to the base plate, said supports also being provided with small transverse and intermediate openings in which are coupled dies of the metal sheets which, allowing their coupling to the corresponding chambers, block them in the insertion end position, which facilitates a fast coupling between the metal sheets and the plastic envelope of the end supports.
  • the air conditioning diffuser louvers disclosed by the invention consists of a tubular louver (1) with a cross section tending towards an isosceles triangle whose legs (2) are facing outwards and are curved-convex in shape, while its asymmetric side (3) meant to face the air outlet opening is curved-convex, with a suitable curvature to allow the outlet section or flow to remain constant in any position or orientation of the louver (1) itself.
  • Said louver (1) also incorporates internally, emerging from its equal sides (2), a pair of partitions (4) that act as retaining means for a stem (5) that emerges from a pair of laminar end supports (6), made of plastic as the stem (5) itself and the assembly of the louver (1), so that the two stems (5) fit tightly in the ends of the louver (1), coaxially, thereby constituting the swivelling axis for said louver (1) allowing its optimum orientation at each instant.
  • the stems (5) performing shaft functions incorporate a plurality of ribs (7) in the sense of their generatrices, determining a pressure coupling inside the louver (1) as well as establishing a stepped rotation for the position changes of the louver (1).
  • the plastic supports (6) are hollow, incorporating a flat intermediate chamber that is open on the edge (8) by which it adapts to the base plate, being meant to receive inside them corresponding metal sheets (9), whose free edge meant to be left outside the corresponding support (6) is provided with an orthogonal end elbow (10) to facilitate their attachment to said base plate.
  • the metal sheets (9) are definitively stabilised inside the supports (6) in the same operation of housing or installing the latter by the existence in each sheet of a pair of dies (11), that define corresponding harpoon-shaped louvers which are elastically deformed when installing the sheet (9) and elastically restore their shape when they reach small side openings (12) operationally provided in the supports (6) that act as stops for said recesses (11 ).

Claims (5)

  1. Lamelles de diffuseur de conditionnement d'air du type dans lequel la lamelle elle-même adopte une configuration tubulaire et est montée avec une liberté de rotation autour d'une paire de supports d'extrémité, mis en oeuvre comme des feuilles ayant des moyens de fixation sur la plaque de base du diffuseur, caractérisées en ce que lesdits supports d'extrémité (6), mis en oeuvre comme des plaques en plastique correspondantes, comprennent des tiges (5) correspondantes sortant de leur face interne sous la forme d'une pièce unique qui constituent ensemble l'arbre de pivotement de la lamelle (1) elle-même, qui est également réalisée à partir de plastique avec le même coefficient de dilatation thermique que les supports (6) et leurs tiges (5).
  2. Lamelles de diffuseur de conditionnement d'air selon la revendication 1, caractérisées en ce que lesdites tiges (5) des supports d'extrémité (6) comprennent des nervures ou saillies (7) dans le sens de leurs génératrices, qui améliorent leur préhension angulaire à l'intérieur des lamelles (1) elles-mêmes.
  3. Lamelles de diffuseur de conditionnement d'air selon les revendications précédentes, caractérisées en ce que la lamelle (1) elle-même a une courbure sur sa face convexe (3), opposée aux ouvertures de sortie d'air, de sorte que la section d'écoulement d'air reste constante indépendamment de l'orientation de la lamelle.
  4. Lamelles de diffuseur de conditionnement d'air selon les revendications précédentes, caractérisées en ce que les supports d'extrémité (6) sont creux, comprenant une chambre intermédiaire couplée, par son bord (8) l'adaptant à la plaque de base, à une tôle métallique (9) prévue sur sa zone sortant du support (6) correspondant avec un coude orthogonal (10) pour sa fixation à la plaque de base.
  5. Lamelles de diffuseur de conditionnement d'air selon la revendication 4, caractérisées en ce que chaque tôle métallique (9) comprend des évidements définissant des rabats (11) pour le blocage sur les ouvertures (12) établies de manière opérationnelle dans la plaque de support (6) correspondante.
