Definitions

  • This invention relates to ventilators for glazed windows or doors.
  • ventilators for direct mounting in glazed panels wherein a prescribed size of circular hole is cut in the glazing and a circular ventilator having a rotatable fan is mounted in the cut hole by means of a two part support assembly.
  • Such ventilators can accomodate different thicknesses of single glazing, but if intended to be used with double glazed panels, very special and expensive steps are required to provide a double glazed panel with the correct size opening.
  • ventilators of elongate form which are mounted in the fixed frame or surround of a window or door.
  • These ventilators may have a slidable obdurator or a pivotal vane or blade for controlling the air flow through the passageway formed or provided in the fixed frame by the ventilator.
  • Such ventilators increase the dimensions of the frame and in certain installations may decrease the effective glazed area or reduce headroom.
  • a ventilator of elongate form comprising a hood unit with a first glazing section and having a support block at each end, and a duct unit with a second glazing section and having a support block at each end mounting a pivotal vane for controlling flow through the ventilator between the hood and duct units, the hood and duct units being assembled and connected together at each end by the respective support blocks with the first and second glazing sections defining a glazing channel for receiving one edge of glazing in use, the respective support blocks being arranged for relative adjustment of the hood and duct units to vary the width of the glazing channel to accommodate different thicknesses of glazing.
  • the ventilator according to this invention has two main parts, these being the hood and duct units which are made up to fit the desired length of the one edge of the glazing. No special profile cutting of the glazing is required.
  • the ventilator provides the glazing channel so that it can be installed in an existing frame or form part of a frame for glazing.
  • the hood and duct units are mounted together by the support block assemblies at each end of the ventilator and which are arranged to permit adjusting movement between the hood and duct units to suit the glazing to be fitted into the channel.
  • the fabricator or installer can use the same ventilator component parts for a wide range of sizes of window or door and thicknesses of glazing.
  • each assembly of the support blocks provides a thermal break interrupting heat transfer between the hood and duct units.
  • any temperature differential between the external hood unit and the internal duct unit will not cause condensation or other deleterious effects.
  • the support blocks are made of a plastics material.
  • the support blocks associated with each end of the duct unit are similar and each mounts a vane support member for limited rotation with each end of the elongate vane extending lengthwise of the duct unit being mounted on a respective one of the vane support members for pivotal movement relative to the duct support blocks.
  • the vane is also isolated to prevent thermal transfer between the duct unit and the hood unit as the vane is supported through the support block assembly providing the thermal break.
  • each hood support block includes a formation complementary to another formation on each duct support block, the complementary formations on the hood and duct support blocks being arranged to inter-engage on assembly to locate the assembled support blocks adjustably together.
  • the complementary formations comprise a wing extending from one support block and a rebate or groove in the other support block for slidably receiving the wing for a range of positions.
  • a member for securing the two support blocks of each end assembly is provided.
  • such member may be a pin, stud or threaded element arranged to extend through a hole and slot in respective ones of the complementary formations.
  • the rebate or groove locates the wing for adjusting sliding movement whilst the securing member is employed to fix the hood and duct units together in their adjusted positions to suit the glazing thickness.
  • the securing member is employed to fix the hood and duct units together in their adjusted positions to suit the glazing thickness.
  • Such an arrangement facilitates fabrication of the ventilator where it is to be incorporated in a window or door system.
  • the relative location of the hood unit and the duct unit assists in fitting and permits the ventilator to be installed in situ from opposed sides of the opening or glazing.
  • the hood unit preferably comprises a hood section and the first glazing section, the sections being provided so that they can be cut to the required length for location and support at each end on opposed hood support blocks to form the hood unit.
  • the hood unit may also comprise fly-netting or gauze seated between the hood section and the first glazing section to prevent ingress of flies or detritus into the ventilator. This may also be a strip for cutting to length.
  • the duct unit preferably comprises the second glazing section, a duct section and a vane section, each of which sections can be cut to the required length for assembly at each end to the duct support blocks and vane supports.
  • the duct support blocks are formed to support and locate the sections, with the vane being arranged to pivot between a seating on the duct section and a seating provided on the second glazing section to control the flow of air through the ventilator.
  • the air passageway through the duct unit is provided between the second glazing section and the duct section.
  • the duct section may be provided with an access aperture for an actuator for controlling the pivotal movement of the vane, and the actuator may be integral with one or both of the vane supports.
  • the ventilator according to this invention be provided as an assembly to window or door manufacturers or as a kit of parts comprising the various sections and support blocks and ancillary parts for assembly to suit a wide range of ventilator lengths and glazing thicknesses.
