Definitions

  • a window frame particularly for a louvre Window, includes a hollow lower sill having an outlet controlled by a flap valve which permits free flow of water from the interior of the sill whilst preventing the entry of air into said interior.
  • the arrangement is such as to entable one to provide a louvre window which is rainproof even under storm force wind conditions.
  • a window frame which includes a lower sill of hollow form which, in use, serves as a reservoir with a valve-controlled outlet communicating with the interior of the sill, the valve of said outlet being a flap valve which permits free flow of water from the interior of the sill whilst preventing the entry of air into said interior, the configuration of the sill being such as to permit, in use, the formation of a head of water therein which exerts a water pressure at the location of the valve greater than the air pressure exerted by a storm force wind.
  • the configuration of the sill is preferably such as to allow the formation of a head of water of at least 35 millimeters.
  • Said lower sill preferably comprises an extruded aluminium box-section element with a synthetic plastics block fitted in each end of said element.
  • Each block preferably has a check-valve-controlled outlet, the valve member in each case comprising a resiliently deformable element of, for example, neoprene, each element including a ribbed formation which is a push fit between a pair of internal walls of the block, said ribbed formation being adjacent an end of the element such that, when said ribbed formation is fitted between said walls whereby said end of the element abuts a stop constituted by a peripheral wall of the block, a lip formation at the other end of the element abuts a cooperating surface constituted by a wall of the extruded aluminium element.
  • the louvre window construction includes upper and lower frame members and a pair of side members to which holders 10 are pivoted.
  • the holders serve to mount the louvre panels and to make sealing engage ment with the side frame members, the holders being constructed and arrangement for movement in the manner set out in British Pat. Specification No. 1,042,731 to which reference should be made.
  • the lower frame member 11 is of hollow form, being of somewhat L-shape in cross-section as can be seen from FIG. 2, and has an internal wall 12, a base wall 13, an external wall 14 of stepped formation and a top wall 15.
  • the outer surface of the external wall 14 is formed with a groove-defining projection 16 to receive a flexible sealing element 17 which seals against the lower most louvre panel when the window is closed.
  • the external wall 15 is formed with a circular hole 18 which is positioned so that any water which drains down the interior of the window panels and reached the projection 16 and the sealing element 17 will enter the interior of the lower frame member and will, as hereinafter explained, pass out of the frame member through a drainage slot 19 formed in the lowermost portion of the wall 14.
  • a polypropylene block 20 (shown in detail in FIGS. 3 to 6) is fitted in each end of the lower frame member 11 and has a cross-sectional configuration such that it is a close fit therein (see FIG. 2).
  • the top wall 15 of the frame member 11 has an inwardly directed projection .21 which locates in a rebate 22 in an end wall 23 of the block 20.
  • the interior of the block 20 can be considered as comprising two portions 24 and 25.
  • the portion 24 communicates with the hole 18 and with the remainder of the interior of the lower frame member.
  • Portion 24 has an end wall 26 which is opposite endwall 23 and is formed with an opening 27 in its lowermost portion; an opening 27a is formed in the lowermost portion of end wall 23, (see FIG. 5).
  • the other portion 25 of the interior of the block contains a flap valve 28 comprising a valve element 29 formed of a resiliently deformable synthetic plastics material, for example, neoprene or a polyurethane.
  • the valve element 29 has a fir-tree section portion 30 at its upper end which tits between a pair of internal walls 31 and 32 extending vertically downwardly from a position adjacent the step in the external wall 14.
  • the fir-tree section portion 30 locates the valve element 29 which, as can be seen from FIGS. 5 and 6, tapers to wards its other end, progressively reducing in thickness.
  • the tapered, free end portion lies against the upper surface of the base wall 13 of the sill, the free end of said tapered portion pointing towards the opening 19 in the wall 14 and the corresponding wall of the block 20 being formed with a registering opening 33 shown in FIGS. 4, 5, and 6.
  • a window frame which includes a hollow lower sill which serves as a reservoir with a valve-controlled outlet communicating with the interior of the sill and the valve having a flap which permits free flow of water from the interior of the sill whilst preventing the entry of air into said interior,
  • the flap is a resilient element mounted in a synthetic plastics block which fits in said hollow lower sill.
  • a window frame according to claim 1, wherein the synthetic plastics block has an interior which is divided into two portions separated by a vertical partition which has an opening formed in the base thereof.
  • each of said synthetic plastics blocks is arranged to communicate with an upright of the frame.
  • each synthetic plastics block is a closed sliding fit in the sill element.
  • the resilient valve member has a lip formation at its other end and wherein the lip formation is inclined to the horizontal and abuts a cooperating surface constituted by a substantially horizontal surface of the hollow lower sill, the upper end portion of the valve member being substantially vertical.
  • a louvre window which includes a pair of uprights, an upper cross member and a hollow lower sill which acts as a reservoir with a valve-controlled outlet communicating with the interior of the sill, the valve having a flap which permits free flow of water from the interior of the sill whilst preventing the entry of air into said interior, said flap being a resilient element mounted in a synthetic plastics block which fits in said hollow lower sill and a plurality of blade holders being pivotally mounted on the uprights of the frame.
