205420 NEW ZEALAND PATENTS ACT, 1953 iicCff/v.rr No .205420 Date; 3 0 August 1983 COMPLETE SPECIFICATION Improvements in or relating to joinery and methods and means for sealing joinery in frames k/We.yi-SAL INDUSTRIES LIMITED a company duly incorporated under the laws of New Zealand of 139 Station Road, Penrose, Auckland, New Zealand hereby declare the invention for which K/ we pray that a patent may be granted to rtfe/us, and the method by which it is to be performed, to be particularly described in and by the following statement: - t~. U o This invention relates to joinery and methods and means for sealing joinery in joinery frames.

It is an object of the present invention to provide joinery and methods and means of sealing joinery in joinery frames which will at least provide the public with a useful choice.

^ Accordingly in one aspect the invention consists in joinery comprising a frame and at least one movable member /L member such as a sash or door in said frame, and/sealing moanc• provided between at least some portions of the frame and some portions of the movable member, said sealing member comprising a fixing member engageable with one or other of said movable members and said frame, and a flexibly resilient sealing strip including a flexibly movable resilient blade, said fixing member having an exposed surface and said blade being attached at one end to said fixing member and disposed when unstressed to lie at an acute angle to said exposed surface with a space between a mating surface of said blade and said exposed surface, said blade being arranged so that when said movable member is moved to the closed position relative to said frame, said blade will cause the gap between the frame and the movable member to close and be held in the closed position by the resilience of said blade and said space between said ouw^eL exposed surface said mating surface to be reduced or eliminated.

In a further aspect the invention consists in a sealing member comprising a fixing member engageable with one or other of said movable members and said frame, and a flexibly resilient sealing strip including a flexibly I movable resilient blade, said fixing member having an X exposed surface and said blade being attached at one end to said fixing member and disposed when unstressed to lie at an acute angle to said exposed surface with a space between a mating—&trrssid blade and said exposed surface, said blade being arranged so that when said movable member is moved to the closed position relative to said frame, said blade will cause the gap between the frame and the movable member to close and be held in the closed position by the resilience of said blade and said space between said exposed surface of said mating surface to be reduced or eliminated.

To those skilled in the art to which the invention relates, many changes in construction and widely differing embodiments and applications of the invention will suggest themselves without departing from the scope of the invention as defined in the appended claims. The disclosures and the descriptions herein are purely illustrative and are not intended to be in any sense limiting.

One preferred form of the invention and modifications thereof will now be described with reference to the accompanying drawings in which: Figure 1 is a cross section of a jamb frame member and associated sash member; Figure 2 is a cross section of a head frame member and associated sash member; Figure 3 is a cross section of a split rail and associated sash member; Figure 4 is similar to Figure 3 but includes a different mounting member for a sealing member moun thereon; 205420 Figure 5 is a cross section of a jamb member and associated sash member with a different form of sealing member associated therewith; Figure 6 is a cross section of a glazing bead mounted on a glazing member; and Figure 7 shows an alternative type of glazing bead.

Referring to the drawings a joinery construction is shown comprising a jamb member 1 with which is associated a sash member 2, the sash member moving in relation to the jamb member in any known way, for example, using a four bar window stay, for example, those manufactured by Interlok. The stay has one of the fixing bars mounted in groove 3 and the other fixing bar is mounted in groove 4. These grooves are continued along the length of the jamb member 1 and of the sash member 2 providing some additional air spaces between jamb and sash for pressure equalization or other purposes.

In one or other of the the movable member i.e. the sash, and the frame member i.e. the jamb 1, and preferably in the frame member 1, a groove 5 is run and a sealing member is mounted in the groove 5. The sealing member includes a fixing strip 10, the fixing strip preferably having one or more ribs 11 on at least one side but preferably on two sides thereof, the ribs 11 sloping outwardly when in the groove so that if the fixed strip 10 is to be removed from the groove 5 these ribs will need to be distorted thus offering added frictional resistance to 205420 such movement. Mounted on the fixing strip 10 is a T head 12 and the T head is extended on one side as an arm 13 of a V member and a blade 14 comprising a free ended flexibly resilient blade which in use contacts a surface 15 of the sash 2 when the sash approaches or is in the closed disposition.

The arm 13 and the blade 14 are both flexibly resilient and the junction 6 of the Vee formed by the arm 13 and blade 14 is arranged to be a flat face of a width which is the sum of the thicknesses of arm 13 and blade 14 adjacent the junction 6, so that when members 1 and 12 are closely approached to each other, the gap between them is filled by arm 13 and blade 14 over a wide range surprisingly, probably due to relative air pressures as between the inside and outside of the e.g. window sash.

Preferably the surface 15 is arranged to close to within 2mm of the surface 16 of the frame and the blade 14 is arranged so that when in the free disposition it will extend a distance of 4mm from the outer surface of the extension 13. Thus irregularities in the space between the frame member 1 and the sash 2 will be taken up by the resilience of the arm 13 and blade 14 and accordingly under normal working conditions the gap between the sash and the frame will be sealed by the arm 13 and blade 14 bridging the gap.

A similar construction is shown in figure 2 in which there is a head frame member 20 and coacting sash member 21 205420 and in this case a groove 22 contains the fixing strip 10 with the blade 14 again positioned so that when the sash 21 is in the closed disposition the gap between the sash and the frame -momteo- 20 will be closed.

Similarly in figure 3 the sash member 25 closes against the seal blade 14, the seal being held in position by the fixing strip 10 onto a frame member 26 forming part of a meeting rail member 27.

The sealing member may also be fitted in grooves on a Transom, both sides of a mullioin and in a groove of a sill or sill board. Additionally seals may be provided on one or other of a door and door frame in a similar manner.

In figure 5 the sealing member is provided with a different form of mounting comprising a mounting member 30 which is preferably made of a more rigid material and, for example, if the sealing blade 31 is, as with the sealing member shown in figures 1 to 3, made of a flexible polyvinylchloride or similar plastics material, the mounting member 30 is preferably made of a more rigid polyvinylchloride or similar plastics material, e.g. unplasticized P.V.C.

The mounting member 30 is preferably of substantially rectangular form with two grooves 32 therein provided to give some flexibility to that member and an open mouthed C-shaped groove 33 is provided.

Fastening is effected by nails 34 passing through the base of the groove 33 and the groove 33 is then filled with 205420 a •€i3"li>g member such as the filling member 34 which may comprise a solid or tubular flexible rod, string or other member made also of a suitable plastics material.

A similar construction is shown in figure 5 but the blade member 41 is mounted on a side extension 42 of the mounting block 30 so that a sash 43 may be sealed against a frame member 44 as shown in figure 5.

The invention also envisages a glazing bead 50 having a foot 51 which fits against part of a glazing member 52 and having a toe 53 which bears against the glass 54 holding that glass against a dry glazing strip 55 against the surface 56 of the glazing member 52. A leg 57 bears against another surface 58 of the glazing member and the glazing bead is held in position by nails 59 passing through the base of a C-shaped groove or slot 60 which is filled with a filling member 61 in the same manner as above described with reference to figures 4 and 5.

As an alternative the invention also envisages a glazing bead 70 having a fixing strip 71 mounted in a groove 72, the fixing strip having preferably ribs such as the ribs 11 shown in figure 1, and the glazing bead 70 is made of a resiliently flexible material such as a suitable plastics material to hold the glass 73 against a dry glazing strip 74 in a glazing member 75.

The constructions described above are applicable to all standard wooden joinery profiles and all styles of wooden joinery, for example casement windows having hinges, four 205420 bar stays or friction stays, awning windows having hinges friction or four bar stays, sliding windows, double hung windows, easy fold windows, gap hung windows or bottom hung windows and is applicable to doors as well as windows in that the sealing member may be readily mounted on the frame or a door so that the blade of the sealing member is positioned to fill a gap between a movable member and a frame for that member. With doors it is preferably for safety reasons that the sealing member is only provided on two or three sides of the door so that there will be some ventilation into a room and at the sill a weather cap on the door over a meeting bar on the frame sill may be provided with an inseal e.g. inseal 300 against vertical surfaces of both when the door is closed. Of course with windows also a lesser number than four sides of the movable member would be accommodated. However generally speaking with windows it is preferably if the sealing member is provided on all four edges between the movable member and the frame therefor. ^ 0 u <■£ ,c (J
