Definitions

  • the present invention relates to a vent for a window and also to a window assembly including the vent.
  • the present invention relates to a vent of the type which is fittable as a separate independent unit along an edge of a window frame and which comprises an elongate duct member provided with an air inlet at one elongate side and an air outlet at the other side, securing means being provided for securing the duct member to the edge of the window frame.
  • a vent is described and claimed in the present applicants UK Patent Application No 8712477 (Published No 2194638A).
  • a ventilator for use in a window assembly is shown in GB-A-2116694 and comprises a front weather strip having the top and bottom longitudinal edges in the form of flange-like bearing webs which carry sealing elements for sealing abutment with co-operating surfaces, specifically wall, frame or glass surfaces.
  • the ventilator is intended essentially for positioning between the window sash and the windows glazing unit in an opening in the unit, and the ventilator comprises a duct body suitably dimensioned for location in this opening.
  • the ventilator is secured to the window assembly by means of a clamping element engaging a side surface of the glazing unit.
  • a further disadvantage of this ventilator is that when the ventilator is installed the weather strip is fully exposed as the two sealing elements have to engage their respective abutting surfaces, and this can adversely affect the aesthetic quality of a building which utilises this ventilator.
  • the vent is fitted to the window frame at an outer edge of the frame by means of securing means securing via said outer edge, and there is neither need to cut an opening in the window frame nor provide an opening in the glazing unit.
  • Different widths of window can be catered for conveniently by cutting the vent duct member to the desired length and fitting standard end caps.
  • Also efficient sealing is achieved by the single seal engaging the front face of the window frame which contrasts with GB-A-2116694 which demands that both of the two sealing elements are in proper sealing engagement with the window assembly and this enables the vent of the present invention to be installed more compactly.
  • the joining means comprises a slotted male-femal interconnection.
  • Said male-female interconnection preferably includes a clip-on facility.
  • the outlet portion includes an air flow control device including apertured plate means so as to provide for example a hit and miss type control.
  • Fittable end covers can be provided to close the ends of the vent assembly and each end cover preferably includes a lateral surface servicing to overlap said apertured plate means.
  • control elements extend laterally from the apertured plate means to facilitate operating movements of the apertured plate means for airflow regulation by the control device.
  • An optional cord control can be fitted to said control elements and preferably the end cover includes guide means for said cord control.
  • a sound insulating baffle member is housed in said duct (or vent assembly) and can comprise a ribbed base with a top plate mounted on said ribbed base.
  • a top vent 9 is provided for a window 1 (see Fig. 11) which in the conventional way comprises a wooden outer frame 2 supporting the sash 3, the window 1 being set into a wall structure between side walls, head lintels and bottom sill.
  • the vent 9 constitutes a separate independent unit which is secured to the head 10 of the window, especially after completion of the window but before the window is offered up to the wall aperture and comprises three parts, namely a main conduit part 11A and a nose 11B and an outlet (or control) part 11C on respective sides of the main conduit part 11A.
  • the main conduit 11A comprises a general box form construction with open ends and a plain interior, the sides 24A, 22A of the conduit 11A defining an air inlet and an air outlet respectively carrying a series of apertures 50A, 50B for lateral airflow through the conduit 11A.
  • the nose 11B and the control sections 11C are joined to the main conduit 11A, by male-female interconnections 51 52, 53, 54 and these interconnections are adapted for snap-fitting.
  • the nose 11B comprises a downwardly angled canopy portion 17 and a downwardly directed flange or nose/drip 18 joined to the portion 17 by a horizontal apertured wall 56, the flange 18 including an inwardly turned lip 18A.
  • the control section 11C shown in Fig. 1 is of channel form and has an apertured bottom wall 22 with opposed groove 57A, 57B adjacent the wall 22 wherein an apertured control plate 21 is slidable.
  • the wall 22 and plate 21 define control means for airflow through the vent 9 operating on a hit-or-miss basis depending on whether or not the apertures of the wall 22 and the plate 21 are in alignment. Movement of the plate 21 is facilitated by gripper elements 23 which have a base 23A generally complementary to an aperture of the plate 21 so that the element 23 can be press fitted into the plate 21.
  • the nose 11B and the control section 11C are open ended.
  • the interconnection 51 comprises a tongue 51A and slot 51B joint whereas the other three interconnections 52-54 are of the bead 58 in groove 59 type.
  • the conduit 11A, nose 11B and section 11C defining a unit are made from suitable metal or plastics material and can be cut in suitable lengths from a continuous length mouldings or extrusions, this latter feature considerably facilitating the use of the vent 9 in a wide variety of different sized windows. Longitudinal grooves in the nose 11A serve to receive a gauze (fly) screen 24.
  • the open ends of the combined unit 11A-11C are closed by left and right handed end closure caps 15 the right hand one of which is shown in Figs. 4 and 5.
  • the cap 15 comprises a recessed base part 60 carrying a set of lugs or tongues 61 engaging with the interior corners of the main conduit 11A, a tongue 62 to locate the canopy portion 17 of nose 11A and a channel form lug 63 locating the control section 11C.
  • the base part 60 presents a laterally directed tab plate 64 on which an end of the air control plate 21 is slidable, the tab plate 64 serving to close off a respective end portion of the air flow control 21/22 so that effective air flow control is always possible from zero to maximum rates irrespective of the cut length of the unit 11A-11C.
  • a stopper block 65 is housed in the base 60 of one side end cap only to set the movement of the control plate 21.
  • a downstand bracket 66 is carried by the plate 64, a hole 67 being present in the bracket 66 for the through-passage of a supplementary control cord 68 fitted to a respective element 23 as shown in Fig. 11; as will be appreciated the control cord 68 will considerably facilitate the operation of the air control 21/22 from a lower level.
  • a removable sound insulating baffle unit or cartridge 69 (Figs. 6 to 8) is housed in the main conduit 11A and comprises a base part 70 having thereon upstanding chevron form walls 71, and a top block 72 mounted on the walls 71 whereby enclosed undulating air passages 73 are present in the unit 69, the wall 71 causing deflection of sound waves in a plane parallel to the base part 70 as shown by the arrows in Fig. 7. Air can pass from the apertures 50 through the air passages 73 to the apertures 51. As can be seen in Fig.
  • the unit 69 will contribute to the strength and rigidity of the main conduit 11A and will be made from suitable lightweight insulating material.
  • the base 70 and top block 72 can be formed by cutting suitable sized portions from continuous lengths of shaped materials.
  • the walls 71 could of course take a different shape: thus Fig. 10 shows walls 71 of different planar profile (in Fig. 10 the thin line arrows indicate the air flow path while the wider arrows show sound wave deflection).
  • an additional sound insulating unit 69A could be located in the control section 11C.
  • the air flow control 22/23 is arranged horizontally, while in the modified vent of Fig. 2 the control 22/23 is arranged vertically: it will be noted however that the horizontal control 22/23 of Fig. 1 provides a maximum discharge area which is greater than that of the vertical control of Fig. 2. It is of course possible for the control 22/23 to have some other shape than that shown, for example, quarter round, and the control could discharge the ventilating air in some further alternative direction.
  • vent 9 Prior to fitting on the window frame 1, the vent 9 is fully assembled, complete with end caps 15 and the sound insulating cartridge unit or units, if required, the nose 11B having been fitted to conduit 11A by firstly placing the tongue 51A in the slot 51B then snapping the bead 58 into the groove 59 control section 11C is fitted by a straight snap fit of the interconnections 53, 54.
  • vent 1 is then placed on the window head 10 and pushed inwards (ie rightwards in Fig 1) to compress the seal 14 against the outer wall 10A of the head 10 and inward movement is arrested by the lip 18A engaging the wall 10A - the outer edge of the lip 18A is set back from the free surface of the seal 14 (see Fig 2) by a predetermined amount to control the achievable compression on seal 14 and also to prevent capillarity attraction of moisture - and in this compressed position the vent 9 is secured to the head 10 by means of screws 16 (Fig 9) passing through screwholes 16A in the conduit 11A.
  • the window 1 with vent 9 in place is now offered up to the window aperture in the building wall and the window surround construction completed so that the vent 9 is located between the building head lintel and the window frame head 10.
  • the above vent 9 of the present invention has the following advantages:-
  • the window vent of Fig. 12 is closely similar to the vent of Fig. 1 and like parts carry like reference numerals.
  • the main conduit 11A is made initially in open form (eg by extrusion ie as an open channel base 13A) and is closed, when the parts 11A, 11B, 11C of the vent are assembled, by virtue of a top wall 33 of the tail section 11C extending over the open channel base, the wall 33 including an additional bead 53A for snap fitting in male/female fashion at the front end of conduit 11A. Therefore the bulk of the parts of vent 9 can be of open channel form and none need be of closed-box form: this considerably conveniences the manufacture of the parts especially where an extrusion process is involved.
  • a sealing strip 34 of hollow cylindrical section is used (the non compressed strip state is shown dashed) differing from the previous strip section, and the strip 34 has a T-head received in a complementary slot in the flange 18.
