Definitions

  • the present invention relates to a ventilation device.
  • Ventilation devices for placement at windows or doors, or in through apertures in walls are well established. Generally these comprise some sort of wall-formation for the provision of an airflow passage across the window, door, or wall, and a usual feature is the location of an airflow control at an end, of said air passage to control the airflow rate between zero (shut) and a maximum (fully open).
  • W093/09327 of the present applicant shows and example of such a ventilation device, and provides a wall-formation comprising identical end members which sit on respective opposed edges of a window frame and which include sockets to receive two parallel plates so as to define said air passage.
  • the airflow control used was of the so called "hit-and-miss" type wherein an apertured slider plate moving in one of the end members could register with corresponding apertures on a fixed wall of this end member.
  • a disadvantage of this control was that the solid portion of this apertured wall constituted a substantial area i.e half the total area and this created inefficiency in the airflow (and performance) of the ventilation device.
  • a ventilation device for placement at a window door, or wall for airflow between an input side an output side includes a basic structure for the formation of an air channel enabling airflow between said input and output sides, and an airflow control comprising a plate means swingable on a pivot device for movement of the plate means between first and second positions defining respectively minimum and maximum airflows via said air channel, said pivot device being arranged such that in a third swung position of the plate means the plate means can be removed.
  • the pivot device is of ball-form cross-section, with a corresponding formation on the plate means whereby the plate means swing about said ball, the ball being recessed so that in said third position the plate means has a further degree of movement freedom relative to the ball for removal of the plate means.
  • a catch means is provided to hold the plate means in said first position, preferably a shut position, and said third position comprises a position when the plate means is swung back just clear of said catch means.
  • at least one additional fill sheet is present in the air channel and serves to avoid or reduce any protuberances to airflow in the channel, the fill sheet preferably having sound absorbing properties for example by being of corrugated form.
  • a curved canopy can be provided at least on of the ends of the air channel for smooth airflow into the channel (or, smooth discharge therefrom).
  • the end members 2, 3 are conveniently cut from a common extrusion, e.g a plastic extrusion, and width variation of the device, can be achieved simply by adjusting the width of the plates 5. Also suitable end closures (see Fig. 5) are provided for the device 1.
  • an airflow control is provided in the form of a pivotal flap 8, conveniently located at the internal side 1, and each end member includes a part circular formation 9A extending the length of the member 2/3 with an adjacent arcuate slot 9B so that, as viewed in cross-section, each end member 2/3 includes a "ball-and-socket" 9 to pivotally receive said flap 8, the flap 8 including a corresponding curved end 8A for reception, in the slot 9B.
  • the end member 2/3 includes lips 10A, 10B against which the flap 8 bears in the closed, first (A) position, a sealing strip 11 serving for complete air-tight closure, while a catch 12 in the form of a protrusion holds the flap 8 in the closed position, the slot 9B permitting the flap 8 to be located in a second (B) open positioned.
  • the ball 9A includes a recess 13 position such that_when the flap 8 is swung (snapped) back just clear of the catch 12 and in a third position (C) the flap 8 can have a further upward movement in the place (P) of the flap 8 to be removed clear of the associated end member 3. Cleaning of the interior of the device is then facilitated. Further sealing strips 14 can be located between the end member 2/3 and the frame 4 to prevent detraction of ventilation performance.
  • No flap 8 is located at member 2 at the external side E, but at this side a curved canopy 15 is positioned at the channel inlet and located by a recess 16 in the member 2 and also by the lip 10A and catch 12.
  • the sheets 17 can comprise readily available corrugated sheeting eg of plastics material including a perforated backing 17A and this material has the added benefit of a sound absorbing property.
  • trims 18 to facilitate positioning of the device 1 relative to a surrounding wall
  • a fly screen 19 may also be present. While the above ventilation device 1 is intended specifically for location at a window, it will be appreciated that the present invention could be applied to vent devices for location at other places eg doors and walls, and also in vent device of different design from device 1.
  • the canopy 15 is provided with a fill sheet 20 similar to fill sheets 17, again being of corrugated form with a smooth outer layer 20A.
  • the fill sheet 20 sits on a flange 15A of the canopy and serves to improve the airflow into the duct 6 and also provide sound insulation.
  • the end members 2, 3 of Fig. 3 have a different profile to those of Fig. 1, in particular the trim 18A being integral with the member 2 in Fig. 3. It may be preferred to have the flap 8 extending on only a portion of the ventilator 1 and in this case a closure plate 21 as shown in Fig. 4 can be fitted on the ventilator portion where no flap 8 is present.
  • the plate 21 includes a curved foot 22 fitting into the circular formation 9A of member 3 and a top bead 23 which can snap fit into the member 3 at formation 12 for location of the plate 21. As can be seen the plate 21 can be arranged to form a uniform wall surface with the member 3.
  • Fig. 5 illustrates the use of end plug members 24 for closure of the ends of the ventilator 1, and these plug members 24 may simply be in the form of foam elements for convenience.
  • the ventilator 1 of Fig. 5 embodies special left and right side flange members 25A, 25B whereby the flap 8 can be positioned at various open settings.
  • Fig. 7 to 10 show the right hand flange member 25B in greater detail: the left hand member 25A is similar, being a mirror image of member 25B. Therefore each member 25A, 25B includes a base wall 26 carrying a series of small projections 27A-E serving as stops for the flap 8, while a bifurcation 28 on the wall 26 serves to receive an end face plate 29 which conveniently can comprise the closure plate 21 described previously.
  • Fig. 5 illustrates the use of end plug members 24 for closure of the ends of the ventilator 1, and these plug members 24 may simply be in the form of foam elements for convenience.
  • the ventilator 1 of Fig. 5 embodies special left and right side flange members 25A
  • FIG. 11 shows the left hand flange member 25A and illustrates the various settings of the flap 8 between the closed position and the maximum open setting. A certain resilience will be present between the flap 8 and the projections 27AE enabling the flap 8 to be pulled (or pushed) passed a projection for movement to a different setting.
