Definitions

  • a window frame is made up of integral profiled bar members and the outer face of each bar is covered with a shield having a trapped air space, which prevents heat transfer through the frame.
  • the invention relates to a frame component, primarily for windows, doors, facades, sashes and the like.
  • An object of the invention is to improve the frame components hitherto proposed in such a way as to eliminate the adverse effects of high thermal conductivity.
  • a framework defining an opening, a plurality of interconnected profiled elongate members each of integral construction, and means defining a closed chamber mounted on each said member to provide at least a thermal barrier, said means including a shield of substantially U- section, and low thermal conductivity plastics material packings interposed between the two free edges of the shield and the corresponding elongate member.
  • the load-bearing frame bars should be provided with two open longitudinal channels parallel to the glazing, in which the pairs of packings are fitted, and pressed together to form a resilient seal by the shield strips.
  • the shield strips may with advantage contain a channel to take window flanning bars and the like.
  • the invention thus differs from the frame components of this type known hitherto, in that is constitutes an undivided, that is to say integral, strengthened construction, which shields the entire window opening, right from the exterior, thereby sealing and insulating it.
  • the construction proper which lies behind this, lies entirely within the warm inner zone and is not subjected to harmful influences of any kind, whether from corrosion, heat radiation or expansion stresses.
  • narrower frames are possible, which ensure maximum possible access for light.
  • the insulating packing strips may also be combined, in accsordance with the invention, into a profile and either enclose a variable insulating air gap directly in front of the profiles bars or serve indirectly, as insulating supports, to provide a sealed and positive means of securing a separate shield strip of light alloy, special steel or the like.
  • the entire load-bearing frame structure including the chambers for the bearing arrangements and fittings, cannot be brought into contact with the outside air, but is surrounded solely by room air at approximately the same temperature.
  • the linear expansion of these profile bars therefore remains low and distortion is avoided.
  • the external shield strips are small in cross-sectional area, have little mass for storing heat and can move freely and noiselessly on the packing strips as guides when temperature differences are high.
  • These shield strips with the insulating packings and the interior frame components enclose a space in which the enclosed air, interrupted at the mitring points, cannot circulate. This air space, moreover, can be further enlarged when still better frame insulation is desired by fitting, for example, triple glazing with two air gaps. External noise caused by the beating of rain and hail is also absorbed by these insulated bearing arrangements and is prevented from penetrating to the interior.
  • FIG. 1 is a vertical section of part of a pivotal casement with frame components in accordance with the invention, the easement being shown in the closed position;
  • FIG. 2 is a fragmentary section of a part of the arrangement shown in FIG. 1, with the casement open;
  • FIG. 3 is a fragmentary section of a part of the arrangernent shown in FIG. 1;
  • FIG. 4 is a vertical section of part of a casement of the pivot, balance or combined pivot/ balance type with frame components in accordance with the invention
  • FIG. 5 is a vertical section of part of a type resembling the arrangement shown in FIG. 4, but slightly modified, with renewable packings in uninsulated form;
  • FIG. 6 is a horizontal section of part of a frame component in accordance with the invention, used as a post with facing.
  • the one-piece, that is to say integral, bar of a window or casement frame, preferably made of light alloy, is referenced 1 and 2 (FIG. 1).
  • the numeral 3 denotes a profiled bar secured to the two bars 1 and 2.
  • longitudinal channels 10 and 11 are provided, between side limbs 12 and 13, the said side limbs extending generally parallel to the plane of the double glazing unit 9.
  • Packing strips, 14 to 16, formed with or without sealing lips are mounted within the channels 10 and 11.
  • the bars 1 and 2 are of barbed section at 1a and 2a, to retain the packing strips 14 to 16 in the longitudinal channels 10 and 11.
  • Elongate lips 14a to 16a, one on each of the packing strips 14 to 16 are sprung around one end of the corresponding side limbs 12 and 13.
  • Shield strips 17, 18 are held in place by the packing strips 14 to 16, the lips 14a to 16a of the packing strips 14 to 16 serving as distance pieces to ensure the maintenance of a gap between the associated shield strips 17 and 18 and the limbs 12 and 13.
  • the width of this gap can be varied by appropriate choice of thickness for the lips 14a to 16a.
  • the shield strips 17 and 18 are of channel section comprising a base and opposed longitudinal side walls extending from the base, a flange extending from the longitudinal edge of each longitudinal side wall being retained within the packing strips 14 to 16.
  • the thickness of the corresponding lips 14a to 16a is such that they are compressed, between the side limb 12 and an abutment comprising the base of the shield strip so as to enhance the sealing action.
  • the packing strips 14 to 16 are of fairly large section, so as to impede heat transfer and increase the quality of the seal. They can be compressed, and when released will recoil resiliently parallel to the plane of the glass pane.
  • FIG. 1 shows the packing when the window frame, though closed, has not yet been bolted.
  • the upper arm 19a of the packing 19 is turned through about 30 to the right by the casement frame, the lower arm 19b in this case being pressed against the flange of the shield strip 17.
  • the tubular packing 20 is resilient. It is easy to insert, being trapped behind the projections, and deforms into a kidney shape section when its fiat rear face is forced against a projecting ridge 3b.
  • the shield strip 21 has a channel 21a, to accommodate a window flanning bar 22. In this way, expensive plastering can be avoided.
  • FIGS. 4 and 5 show quite clearly that, because of the form of construction of the frame bars 1 and 2, the shield strips 17 and 18 are considerably narrower than' in the embodiment illustrated in FIG. 1.
  • FIGS. 1 to 5 show frame constructions with easements for windows with interior glazing
  • FIG. 6 is a cross-section of a sash or post 25 with external glazing
  • the post 25 can be connected to a detachable holdins s rip 26.
  • Inserted in both ends of the holding strip 26 are packing strips, 27, which serve at the same time to hold a shield strip '28 in place.
  • a sealing compound fillet is provided at 29.
  • the packing strips 27 can also be used in short lengths, inserted at suitable intervals, if they are made from solid, injection-moulded insulating material, the gaps between being hermetically sealed.
  • each packing strip is compressed between the strip 26 and an abutment on the respective longitudinal side wall of the shield strip 28.
  • the air gap behind the shield strip 28, which may be extra large, for example, may also be filled additionally with foamed plastics material 30. This, because of its closed cells, prevents all air circulation and makes even better insulation possible.
  • foamed plastics material 30 because of its closed cells, prevents all air circulation and makes even better insulation possible.
  • the holding strip 26 itself is in the warm zone and the heat transfer paths form outside via the connecting bolts are interrupted.
  • the form of the holding strips and inserted insulating packings may vary according to the size of the shield strips 28 and the performance expected of them; but it remains important that the heat transfer paths should be interrupted by insulated packings.
  • the constructions hereinbefore described afford frontal insulation of the inside frame construction and, in con junction with the double glazing units, provides a complete heat barrier, which markedly increases the continuously effective equalisation of air temperature within the rooms, saves heating costs and prevents the formation of water of condensation. Comfort in the occupied rooms is thereby considerably increased in both hot and cold climates.
  • a pivotal casement frame including two frameworks, each said framework defining a plane opening and comprising a plurality of interconnected parallel profiled elongate members, means defining two opposed longitudinal channels on each said member, the side limbs of each said channel extending generally parallel to the plane of said opening, means defining a closed chamber on each said member to provide at least a thermal barrier, said means comprising a longitudinal shield, said shield including abutment means, opposed interconnected longitudinal side walls, and a flange extending from the longitudinal edge of each said side walls, and a low thermal conductivity packing interposed between each said channel and the shield, each said packing including a first elongate lip retained within the channel, and a second elongate lip extending between the channel and the abutment means of the shield, to space the shield therefrom, the said flange extending from the longitudinal edge of each said wall of the shield being retained within a respective packing, and a profiled elongate member lying between juxtaposed parallel elongate members of said two frameworks and
  • T-section packing of T-section retained in said second channel-section part said T-section packing being deformed during fitting so that the cross member of said packing forms an angle of approximately 15 to the central leg of said packing and which, when the casement is closed, makes contact with the shield of the two said juxtaposed members so that the two halves of the cross-member of said packing make angles of approximately 30 to the central leg of said packing.
