Definitions

  • This invention relates to a strip ventilator.
  • a strip ventilator generally comprises an elongate strip of rigid material having a lower portion for receiving an upper edge portion of a glazed panel, an upper portion for location in a window frame and an intermediate portion having at least one opening and, in combination with the strip, a shutter moveable relative to the intermediate portion to control airflow through the intermediate portion.
  • An example of a strip ventilator is disclosed in GB 2 168 801A.
  • each ventilator In order to reduce the cost of manufacture of strip ventilators, it is desirable to reduce the number of components which comprise each ventilator. This may be achieved by forming the strip as a single component whereby the upper, lower and intermediate portions are integral. However, it is generally necessary to provide such a ventilator with a hood so that there is no direct passage to and from the opening or openings of the intermediate portion in a direction normal thereto. The presence of a hood thus reduces any tendency for extraneous air currents to pass through a ventilator when in an open condition.
  • a hood necessitates manufacture of a separate component and also requires skill, labour and time to assemble and secure each hood relative to a corresponding integral ventilator strip.
  • the invention is characterised in that an elongate strip is formed as a single component including an integral formation extending adjacent the intermediate portion, the formation defining an opening which is below the or each opening in the intermediate portion thereby ensuring that there is no direct passage to and from the said opening or openings in a direction normal thereto.
  • an extrusion 10 of aluminium comprising a lower portion 11, an upper portion 12 and an intermediate portion 13.
  • the lower portion 11 is of substantially inverted U-shape transverse cross section one opposite facing portion 14 of which is of greater vertical dimension than the other opposite facing portion 15 thereof.
  • the upper portion 12 of the extrusion 10 is of U-shape transverse cross section, the opposite facing portions 16 and 17 being of equal vertical dimension.
  • the intermediate portion 13 comprises a rectilinear wall 18, a curved wall 19 and upper and lower bridge portions and 21 connecting the walls 18 and 19 in spaced relation one to another.
  • the rectilinear wall 18 is provided with a series of square apertures 22 extending longitudinally of the extrusion 10.
  • the curved wall 19 extends downwardly from the upper bridge portion 20 in a direction parallel to the rectilinear wall 18, then curves outwardly away from the rectilinear wall and continues in a downward direction parallel to the rectilinear wall 18 to form a skirt 23 having a lower lip 24.
  • the curved wall 19 is provided with an internal longitudinally extending projection 25 which defines an internal longitudinally extending recess 26 at the junction of the curved wall 19 and the skirt 23.
  • the skirt 23 is of such dimension that the distance of the lip 24 from the upper bridge portion 20 is at least as great as the distance of lower margins of the apertures 22 in the rectilinear wall 18 from the upper bridge portion 20. Also the distance of the lip 24 from the rectilinear wall 18 is substantially the same as the distance separating the opposite facing portions 14,15 of the U-shape lower portion 11 of the extrusion 10. In consequence, the lip 24 is located substantially vertically above the wall 14 of the lower portion 11 of the extrusion 10.
  • the upper bridge portion 20 is provided with an inwardly extending longitudinal projection 27 defining a longitudinal recess 28 adjacent the rectilinear wall 18 and a longitudinal recess 29 remote from the rectilinear wall 18.
  • the lower bridge portion 21 is provided with an inwardly extending longitudinal projection 30 defining a longitudinal recess 31 adjacent the rectilinear wall 18 and a longitudinal recess 32 remote from the rectilinear wall 18.
  • the lower bridge portion 21 outwardly of the outer recess 32 slopes downwardly in a direction from the rectilinear wall 18, as shown at 33.
  • the lower and upper extended portions 15, 16 are each provided with an inwardly extending flange 34,35.
  • a strip ventilator 36 comprising two extrusions 10 mounted in back to back configuration and secured one to another by means of a pair of elongate connecting members 37, 38 of plastics material each havaing a pair of inwardly turned flanges 39,40 for engaging with the corresponding flanges 34, 35 of the portions 15, 16 of the extrusions 10 and connecting the extrusions 10 in spaced relation one to another.
  • the ventilator 36 also includes a pair of shutters 41, 42 each provided with a series of square apertures 43 similar to the square apertures 22 of the extrusions 10, the shutters 41, 42 each being located in a corresponding pair of the recesses 28, 31 of a corresponding extrusion 10 and slidable therein in a longitudinal direction of the extrusions 10.
  • the ventilator 36 also includes an elongate mesh flyscreen 44 which is received in the recesses 26, 32 of one of the extrusions 10.
  • the ventilator 36 is located in a window frame 45 having a rebate 46 and a double glazed unit 47 an upper edge 48 of which is spaced from an upper portion of the frame 45 such that when the upper edge 48 of the glazed unit 47 has the ventilator 36 received thereon the edge 48 is received between the opposite facing portions 14 of the two extrusions 10, the portions of the extrusions 10 extending upwardly beyond the curves of the walls 19 being received in the rebate 46 in the upper portion of the window frame 45.
  • Each end cap 49 is a substantially rectangular block comprising an end wall 50 having a recess 51, a pair of bores 52 and 53 and a pair of angled slots 54 and 55.
  • the arrangement is such that an end wall 50 of one end cap 49 is placed in abutment with one pair of end walls of the extrusions 10 of the ventilator 36 such that one end portion of the flyscreen 44 either enters in or is aligned with a corresponding one of the slots 54,55 and the recesses 29 of the extrusions 10 are aligned with corresponding bores 52,53. Screws then are inserted in the bores 52,53 and screwed into the recesses 29 thereby securing the end cap 49 to the ventilator 36. The process is repeated with the second end cap 49 thereby securing the second end cap 49 to the ventilator 36.
  • the assembly then is mounted on the upper edge 48 of the glazed unit 47 and sealed thereto by means of seals 56 and the unit 47 is inserted in the window frame 45 and sealed therein by means of seals 57, as shown in Figures 3 and 5, and the upper portions of the extrusions 10 entering in the rebate 46 such that the skirts 23 are located adjacent exposed surfaces 58 of the window frame 45.
  • Movement of the shutters 41,42 is possible, although the shutters may be of the same length as the extrusions 10, because any overlap of an end portion of a shutter 41,42 beyond an end portion of an extrusion 10 is accommodated by the recess 51 in the adjacent end cap 49.
