ABSTRACT:
BACKGROUND OF THE INVENTION
This invention concerns glazed roofs.
Conservatories with pitched roofs can be made either with glass or plastics glazing panels. The panels are held in place by cappings secured to glazing bars and pressed down onto panels. Glass panels are relatively heavy and will tend to slip downwards under their own weight unless supported at bottom edges.
Plastics roofing panels, whilst being lighter than equivalent glass panes may also be liable to slip downwards, especially if the roof pitch is over 35° and/or there is expansion of the glazing bars or cappings.
It is known to provide pegs or the like fitted to glazing bars or to eaves beams against which glass panels abut to prevent downwards slippage thereof. However, contact with the glass panels is over a very small area and can cause damage to the glass panels.
Furthermore, in some roof situations, such as for hipped roofs, the panels do not have their bottom edges at right angles to glazing bars supporting them along their sides, which can put greater pressure on supporting pegs.
SUMMARY OF THE INVENTION
An object of this invention is to provide an improved support for glazing panels whether of glass or plastics for use in constructing pitched glazed roofs, such as of conservatories and that may be used in different pitched roof situations.
According to this invention there is provided a support for glazing panels for use in constructing pitched glazed roofs comprising a bracket securable to a glazing bar, a peg adjustably positionable relative to the bracket and securable thereby and a buffer mountable on the peg for abutment by a glazing panel.
The peg is preferably at one end of a plate and the plate and bracket preferably have mutually engaging formations. More preferably, the plate and bracket have mutually engaging ratchet surfaces, whereby once the bracket has been secured to a glazing bar, the plate can be moved under the bracket to a desired position but cannot be pulled back therefrom by the weight of a panel abutting the buffer on the peg.
The buffer preferably comprises a sleeve that fits onto the peg. The buffer is preferably made of rubber, neoprene or any other suitable elastomeric material. The buffer is preferably shaped to provide at least two bearing surfaces that can be selectively used to abut a glazing panel. The peg preferably has a base that has a major dimension and a minor dimension and the major dimension of the peg is preferably angled at other than 90° to a longitudinal axis of the plate. The peg preferably has one shorter side chamfered so that the peg narrows upwardly from its base.
The sleeve has an aperture corresponding in size and shape to the peg i.e. having a major dimension and a minor dimension. The at least two bearing surfaces of the buffer are preferably of different lengths, a shorter bearing surface being generally parallel to the major dimension of the sleeve aperture and a longer bearing surface being at an acute angle to said major dimension of the sleeve aperture. The bearing surfaces are preferably not smooth and are preferably undulating or ridged for grip.
The buffer can, therefore, be used in different orientations to suit the situation. The buffer can be used with either a longer or a shorter bearing surface presented to the glazing panel to be supported and can be used either way up, so that the presented bearing surface is parallel to the supported edge of the glazing panel.
For practical purposes, the angle of the peg and the relative angles of the bearing surfaces of the buffer are chosen to enable the support to be used in a transom rafter situation at 90°, a Victorian hip situation at 67° and a Georgian hip situation at 45°.
