GB2138875A - A glazing gasket - Google Patents

Abstract

The gasket is produced with an inbuilt heating element, and so overcomes the condensation problem in windows. The heating element is contained in a wedge gasket, or is added on to it. <IMAGE>

Description

SPECIFICATION A glazing gasket, having included into its profile a conductor, or conductors, for energisation to reduce or control condensation on window frame and door structure's From one aspect, the present invention relates to known types of electrical conductors being included into known types of glazing gaskets.

Such known glazing gaskets are produced for the window, door, and glass industries and are used to retain glass into known frame structures usually manufactured from aluminium or UPVC. At present glazing gaskets are manufactured to known profiles comprising mainly of the "wedge" and "bead". The wedge, is designed, to enter the void between the glass face and the glazing leg of the frame extrusion and lead the bead section into its location where it engages into an accommodation on the frame member.

Figure 1 shows an enlarged typical cross section.

In use gasket retains glass or glass units against the glazing beads all composite within frame structures of known window and door assemblies. At present each glazed panel, of a windo or door assembly, is held in place by a complete length of gasket about it's periphery and it terminates at a convenient point in that singular glazed panel.

In the matter of this invention the wedge of the gasket will vary from known types in that it will be extended or re-designed in profile, as necessary, to accommodate the electrical conductor conductors.

Such electrical conductors will have resistor value in order that they function as heater elements. Wherein on energisation controlled heat is transmitted throughout the panel and frame assemblies all as peviously disclosed.

The material used in extruding, molding, or forming the gasket will be suitable to both conform to the requirements of the electrical aspect of the invention and also to suitably hold the glass firmly in position. Neoprene and PVC are typical of the plastic type materials currently in use for the manufacture of glazing gasket.

According to a second aspect of the inventio the manufacture of the energisable gasket would be achieved by bringing together known heating elements and known gasket types and bonding one to the other, in known processes, such as "cross heading', in the plastics extrusions industry.

According to a third aspect of the invention the manufacture of this energisable gasket would be achieved by bringing together new types of heating elements and bonding or molding them onto or into known types, or sections, of glazing gasket. Conversely known types of heating elements would be molded or bonded into or onto new types of glazing gasket.

Out enquiries and re-search in the industry concerned in producing glazing gaskets for the glass and glazing trade have shown that the aforesaid combinations are all viable and practical.

In use, when such aforementioned gaskets are applied to window structures having more than one glazed panel it is only necessary to check-out a short section of the glazing leg in one panel in order to continue over a mullion or transom and enter into the adjacent gasket void via a similar check-out. Such check-outs and the heating element crossing the member would be concealed by a shallow decorative capping plate.

Again, in use, when gaskets are required to pass from one glazed panel to an adjacent panel that is an opening light, window, casement, sash or doorl-whether traditionally hung on hinges at its side, top or bottom or variably hung on centre or out of centre pivots continuity is maintained for energising the gasket by using connectors described and exposed elsewhere.

In use, energisation of the gasket system will provide controlled heat to the area of the faces of the frame structure exposed to the water vapour, contained within the room, and so prevent condensation forming on the afore mentioned faces all as previously disclosed.

Furthermore in the aspect of electrical circuitry the gasket will be so arranged to give any number of wire connected in series or parallel or series-parallel in order to produce the desired wattage.

Electrical power will be from sources such as transformers or direct from the mains and control will be from thermostats or other devices as previously disclosed.

1. The energisable glazing gasket will perform all the known functions of conventional glazing gaskets when used in glazing applications.

2. In use the energisable gasket will, when a suitable current is passed through, control frame condensation and heat loss in aluminium and UPVC window and door fabrications and structures.

3. When used as a substitute to replace known gasket types in window and door structures, already installed and existing, it will when a suitable current is passed through control frame condensation and heat loss in aluminium and UPVC window and door fabrications and structures.
