Definitions

  • the invention relates to a ventilation louvre assembly, in particular for installation together with a window, comprising a number of horizontally arranged louvre blades which at their ends are mounted in oppositely disposed vertical frame members.
  • each of the vertical frame members is constituted by a profiled rail normally manufactured for use as a window frame member and having at its one side a groove normally provided for receiving a lateral edge of a thermo pane and which is externally defined by a stationary wall of the profiled rail and internally by a glazing strip made from a resilient material, in particular plastics, and that an insert rail bent angularly substantially in L-shape is designed to be arranged in said groove with one part of the L-shape abutting on said stationary wall of the profile rail member, punched, protruding hook members with an upwardly facing opening being provided on said one part for receiving and retaining a downwardly facing edge portion at one lateral edge of each louvre blade, each louvre blade having at its opposite lateral edge an upwardly projecting edge portion and being designed so that the distance between said two, substantially parallel edge portions is a little larger than the distance between the part of the insert rail engaging the stationary wall of the profile rail and the side of the glazing strip facing on to
  • the insert rail per se is a comparatively cheap element obtained by punching out and bending substantially thin sheet metal.
  • Window frame profiles of the type that may be used in connection with the present invention are inter alia known from EP patent application No. 87114987.8 and are manufactured in large-scale production as standard goods in the form of extruded aluminium profiles.
  • the profile rails serving as vertical frame members have a substantially T-shaped cross-section, in which said stationary wall forming the external wall of said rail constitutes one half of the transverse branch of the T-shape while the stem of the T-shape in the vicinity of its free end has a countersunk notch with edge cutouts for receiving opposite edge beads on an elastically resilient part of the glazing strip, thereby allowing the glazing strip, after one edge bead has been inserted into the matching edge cutout in said groove, to be finally mounted, by pressing under snap engagement the other edge bead into the other edge cutout.
  • a further development of the ventilation louvre assembly according to the invention is characterized in that a countersunk spline generally provided in the inner side of the glazing strip facing away from said groove for receiving a sealing strip serves to mount an insect screen which is secured in the spline by means of a retaining strip.
  • FIG. 1 only illustrates a single louvre blade 1 in an embodiment of the ventilation louvre assembly according to the invention which, however, includes a considerable number of such horizontally superposed louvre blades mounted at their ends in oppositely disposed vertical frame members.
  • Each of the vertical frame members is constituted by a standard profile rail 2 of extruded aluminium.
  • the profile rail 2 has a substantially T-shaped cross-section in which one half of the transverse branch of the T-shape forms a stationary wall 3 constituting the outer delimitation of a groove 4 which in normal use of the frame serves to receive a gasket for sealing against an edge portion of a thermo pane.
  • the stem 5 of the profile is in the vicinity of its free end formed with a countersunk notch 6 with edge incisions 7 and 8 for receiving oppositely positioned edge beads 9 and 10 on an elastically resilient part 11 of a glazing strip 12 made from an elastically resilient material, e.g. plastics, and which together with the stationary wall 3 defines a groove serving to receive, in normal use of the profile, the edge portion of a thermo pane.
  • an insert rail 13 substantially of L-shaped cross-section is designed to be positioned with one end of the L-profile in engagement with the external stationary wall 3 of the profile rail 2.
  • the portion 14 of the L-profile of the insert rail 13 facing the wall 3 is provided with punched-out, protruding hook members 16 with an upwardly facing opening 17.
  • the L-shaped insert rail has a likewise punched projection 18 to retain the downwardly projecting edge portion 15 of the louvre blade in hook member 16.
  • the louvre blade 1 has an upwardly projecting edge portion 19 mainly parallel to the edge portion 15.
  • the central section 20 of louvre blade 1 adjoins edge portions 15 and 19 at bending lines 21 and 22.
  • Louvre blade 1 is further shaped so that the distance between edge portions 15 and 19 when unloaded is a little larger than the distance in the groove between insert rail 14 and glazing strip 12, thereby effecting upon mounting glazing strip 12 by snap engagement, as described above, a clamping of louvre blade 1 which is then retained in place at a well-defined predetermined angular position of the central section 20.
  • said spline may in an embodiment of the ventilation louvre assembly according to the invention be used for mounting an insect screen 24 affixed in spline 23 by means of a retaining strip 25 acting further as sealing strip against an internal shutter 26 for covering up the light area of the ventilation louvre assembly.
  • Shutter 26 may in a manner, not shown, be hingedly connected with one of the vertical frame members.
