ABSTRACT:
BACKGROUND OF INVENTION
This invention concerns glazed roof construction and, in particular, concerns glazed roofs formed of ducted plastics panels supported between glazing bars.
Plastics panels for forming glazed roofs are typically produced in standard widths, for example, of 500 mm. Every attempt is made, when designing say a conservatory having a glazed roof, to use a roof requiring only standard width panels, in order to facilitate erection of the roof. However, in some situations, non-standard panel widths are needed because of space considerations. Then standard panels have to be cut down and special arrangements made at the cut down ends to finish the conservatory roof. The plastics panels used may have formations that enable them to be linked directly to glazing bars but if they are cut down, those formations are lost.
There are three typical situations in which non-standard widths panels may be required. The first situation is for a lean-to type of conservatory where the roof panels extend from a wall. If the roof is of non-standard width it is customary to put equal width non-standard panels at each end of the roof for symmetry. The second situation is in a typical duo-pitch conservatory where roof panels are parallel to a wall against which the conservatory is built. In this situation it is customary to put the non-standard width panels abutting the wall.
The third situation is where a conservatory is fitted into a corner and so abuts against two walls, and then the two walls which may not actually be at right angles to each other. In that situation typically the non-standard width panel may have to be cut down to be wider at one end than the other, to accommodate the non-right angle corner, into which it is fitted.
SUMMARY OF THE INVENTION
The problem, therefore, exists of having to accommodate non-standard width roofing panels, cut down from standard width panels to form a satisfactory connection to a wall or to finish off ends of a conservatory roof in a neat and weather proof fashion.
According to this invention it is proposed that an adaptor be provided that can be located in a cut-down ducted plastics roofing panel, the adaptor having a formation thereon for coupling to a glazing bar, such as a conventional end glazing bar or a glazing bar adapted for connection to a wall.
The ducted plastics glazing panels for use with the adaptor typically have a top wall, bottom wall and connecting walls therebetween forming ducts through the panels. The panels may also have intermediate walls parallel to the top and bottom walls to subdivide the ducts. These intermediate walls are usually thinner than the top and bottom walls. To prepare a ducted plastics panel for the adaptor, the panel is cut to the desired size and then any intermediate walls stripped out to leave an open space between the top and bottom walls and the last connecting wall. The adaptor is preferably located in that space by any suitable means. Double sided adhesive tape or screws are the preferred means for locating the adaptor in a panel end space.
The preferred adaptor is generally rectangular in section and may be ducted to improve thermal properties. The ducts are preferably one on top of the other. The adaptor may have its top and bottom walls recessed to provide sites for the double sided adhesive tape. The adaptor preferably has at least one formation extending therefrom whereby it can be coupled to a glazing bar having complementary coupling formations.
The preferred glazing bar for use with the adaptor of the invention has a stem, preferably a ducted stem, with a top formation adapted to receive engagingly formations of a capping, and a groove or slot along one side of the stem for coupling with a corresponding groove or slot of the adaptor coupling formation.
For a glazing bar to be used against a wall, the other side of the glazing bar preferably has a plate linked thereto, which plate itself is, in use, abutted against a wall and secured in place, usually by screws. The glazing bar is preferably arranged to have a bottom cover strip mounted thereon to bridge between the underside of the glazing panel and the wall against which the glazing bar is abutted.
A glazing bar to be used with the adaptor of the invention at a gable end of a conservatory roof preferably has a face to take screws for securing the glazing bar to a supporting side wall, such as provided by window frames. The glazing bar preferably also has a flange on which may be mounted a cover for concealing the outer side of the glazing bar. The cover is preferably adjustably positionable relative to the supporting wall or window or a spacing plate mounted on the supporting wall or window.
According to another aspect of this invention this type of glazing bar may be used without the adaptor to form gable ends of conservatory roofs.
The preferred adaptors of the invention are formed as extrusions from plastics material. The glazing bars are preferably extruded from aluminum.
