Definitions

  • This invention relates to a thermal-break frame member, and to a method for its production, wherein the frame member is intended for use in the manufacture of door or window frames or the like; the frame member being of the type comprising two elongate extruded, rolled, drawn or folded elements joined together by thermally insulating material.
  • a composite thermal-break frame member comprising an interior frame element in the form of an elongate plastics extrusion and an outer frame element in the form of an elongate metal extrusion, e.g. aluminium.
  • the metal extrusion is initially engaged with the plastics extrusions by means of co-operating formations on the two elements to define an elongate channel therebetween bounded in part by the plastics extrusion and in part by the metal extrusion with the base of the channel being provided by part of the metal extrusion.
  • a liquid resin material - is then poured into the channel and, after the resin has cured to a rigid condition, an elongate section of the metal extrusion providing the base of the channel is cut away whereby the plastics and metal frame elements are connected to one another only by the thermally insulating resin material.

  • two separate metal extrusions which may have differing surface finishes or colours are initially interengaged in a self-supporting manner to provide a channel therebetween into which the resin material may be poured. After the resin material has cured the base of the channel is "de-bridged" in a similar manner to that disclosed in GB-A-2 196 369.
  • the two elongate metal extrusions are initially joined together by a snap action between a continuous elongate headed flange on the one extrusion engaged between two spaced apart elongate headed flanges on the other extrusion.
  • Each of the said spaced apart flanges has some degree of resilience whereby the headed flange on the one extrusion may be continuously engaged with a snap action between the two spaced apart flanges on the other extrusion.
  • a method of producing a thermal-break frame member comprising two elongate metal frame elements interconnected by a thermally insulating material comprising the steps of: assembling two said frame elements together in side-by-side engagement with one another to define an elongate first channel therebetween; engaging releasable engagement means with said elements to maintain the assembled elements in self-supporting relationship with one another; pouring a thermally insulating material in liquid form into said first channel and allowing said thermally insulating material to cure to a rigid condition; removing said releasable engagement means; and removing a part of said first channel to provide a thermal-break frame member wherein the two said frame elements thereof are connected together only by the rigid thermally insulating material.

  • the member 26 also includes a pair of flanges defining a groove 34 adjacent the upper end of the member 26 for the reception of a sealing gasket (not shown) to engage an internal face of a glazing panel.
  • a continuous radiused undercut groove 35 is provided at the transition between the undersurface of the web portion 28 and that face of the downwardly directed flange remote from the lip 32.
  • a continuous radiused transition 37 is provided between the undersurface of the web portion 28 and the adjacent face of the member 26 below the web portion.
  • a further continuous lip 39 is provided on the member 26 below the web portion 28 at a position such that, when the elements 10 and 12 are engaged in side-by-side relationship with one another as further described below, the lip 39 on the interior frame element 12 will extend in parallel opposed laterally spaced relationship with the lip 22 on the exterior frame element 10.
  • FIG. 2 of the drawings the two frame elements 10 and 12 are shown loosely engaged with one another as part of the method of producing the finished frame member.
  • the lip 30 on the interior frame element 12 is engaged behind the lip 20 of the exterior frame element 10; these two lips 20 and 30 thereby providing a co-operating fulcrum means extending continuously of the length of the frame elements 10 and 12.
  • the outer surfaces of the lips 32 and 33 of the interior frame element 12 are in abutting contact with the external surface of the end 36 of the box section body 14 of the exterior frame element 10 and, in this abutment position, there are defined respective upper and lower channels 38 and 40 each bounded in part by each of the two frame elements.
  • the upper channel 38 is defined between the outer face of the member 26 above the web portion 28, the upper surface of the web portion 28 and the outer end of the flange providing the lip 20.
  • the lower channel 40 is defined between the outer face of the member 26 below the web portion 28, the under surface of the web portion 28 and the respective flanges providing the lips 22 and 32.
  • Releasable engagement means conveniently comprising a continuous elastomeric hollow tube 42 is insertable within the upper channel 38 ' as shown in Figure 3 and, when this resilient wedging means has been so inserted as shown, the two frame elements 10 and 12 are retained together in self supporting relationship with the abutments provided respectively by the lips 32 and 33 and the end 36 resiliently biased into contact with one another by the resilient wedging means 42 about the fulcrum provided by the co-operating lips 20 and 30.
  • the self supporting assembly shown in Figure 3 is then inverted so that the channel 40 is uppermost, and a thermally insulating resin material in liquid phase is poured into this channel 40 and allowed to cure to a rigid condition in known manner.
  • the radiused transitions 35 and 37 facilitate flow of the liquid resin to fill the channel 40 without air entrapment whilst the undercut form of the groove 35 provides a positive mechanical keying of the cured resin thereto.
  • Further enhanced keying of the cured resin to the metal parts of the channel 40 is provided by the free ends of the opposed lips 22 and 39, by continuous ribs 41 provided on the undersurface of the web portion 28, and by serrations or the like (not shown) cut into the resin-contacting surfaces of the channel 40.
  • the cured thermally insulating material 44 is shown in Figure 4, where the assembly of frame elements 10 and 12 has been re-inverted, and the resilient means 42 is then removed from the channel 38.
  • the assembly is then de-bridged by removing a part of the base of the channel 40 i.e. by cutting out a continuous strip as at position 46 from the web portion 28 of the interior frame element 12 whereby, as shown in Figure 5, the finished de-bridged frame member comprises the two frame elements 10 and 12 rigidly connected together only by the cured thermally insulating resin material 44.
  • the rigidity of the de-bridged frame member is enhanced by the provision of the lip 33 abutted against the opposed face of the end 36 and by the interengagement of the lips 20 and 30 since, as will be seen from Figure 5, such abutment and interengagement will provide resistance against bending apart of the frame elements 10 and 12.

  • the two extrusions are then biased about the fulcrum provided by the interengaged lips 20 and 30 to an angular orientation determined by the positioning of the abutments 32 and 36 which defines relatively rigidly the shape of the channel 40 into which the thermally insulating resin material is subsequently poured.
  • the finished de-bridged thermally-broken frame member shown in Figure 5 is subsequently assembled into a full window or door frame and, in the orientation shown in Figure 5, such a frame member would comprise a lower horizontal member of the frame.

Abstract

Un élément de cadre pour fenêtre ou porte comprend deux éléments métalliques extrudés, séparés par une résine thermiquement isolante. Les éléments (10, 12) sont initialement imbriqués les uns dans les autres en une relation côte-à-côte par des rebords respectifs coopérants (20 et 30) afin de former un canal supérieur (38) et un canal inférieur (40). Un tube élastique (42) est ensuite calé dans le canal (38) pour retenir les éléments tel un ensemble auto-porteur, qui est par la suite inversé, et une résine sous forme liquide est versée dans le canal (40). Après dépôt de la résine, le tube (42) est retiré et le canal (40) est 'déporté' en sectionnant une partie de sa base de sorte que les éléments (10 et 12) soient raccordés uniquement par la résine thermiquement isolante (44). L'invention permet d'utiliser des éléments à cadre metallique ayant des finitions de surface et/ou des couleurs différents les unes des autres.
