Abstract

A window frame moulding comprises a support 1 for a pane of glass, a channel 2 disposed adjacent one side of the support and one or more apertures 4 communicating between the channel 2 and another side of the support. The moulding serves to collect and conduct condensation from the interior of a window frame 10 to the exterior. <IMAGE>

Description

SPECIFICATION Improvements in or relating to window frames This invention relates to window frames and in particular to means for removing condensation from the interior thereof.

According to the present invention a moulding comprises a support for a pane of glass, a channel disposed adjacent one side of the support and one or more apertures communicating between said channel and another side of the support.

Preferably the moulding is arranged to form part of a window frame and the channel is disposed in use on the interior of the window frame with the one or more apertures communicating with the exterior of the window frame. In use of a moulding in accordance with the invention condensation which forms on the interior of the panel of glass drains into the channel and is conducted through the one or more apertures to the exterior. Free passage of air through the apertures serves to keep the latter clear of blockages.

Means are preferably provided for securing the moulding within a window opening. Such means preferably comprise a perforated flange provided upon the moulding through which screws or other fixing means may be inserted. Adhesives may alternatively be used.

The moulding is formed integrally for example by extrusion stamping, pressing or other moulding of a metal such as aluminium or of a plastics material. Preferably the channel is arranged so that in use it is disposed at a lower level than the support. In this case apertures may be conveniently provided communicating between the bottom of the channel and the exterior side of the structure.

The support and channel are preferably provided with a common wall. The support may conveniently also have the form of a channel of a size suitable to receive an edge of a pane of glass.

In this case the two channels may have the general shape of a letter E rotated through 900.

A moulding in accordance with this invention may be used to modify an existing window frame.

To achieve this the glass is removed from the frame and the moulding secured to the lower edge of the frame. The support for the pane of glass is arranged to be coplanar with the original location of the glass. The glass is cut to accommodate the moulding in the window aperture and then reinserted into contact with the support and the side and top of the frame.

Mouldings in accordance with the invention may alternatively be incorporated into new window frames. Mouldings may also be provided for use with double glazed window. These contain two supports with a drainage channel provided adjacent the interior surface of the inner support.

End pieces or end caps may be provided at the ends of the drainage channels although these may be omitted and the ends of the channel sealed with putty used to secure the pane of glass within the frame.

A flange may be provided which in use covers the position where the moulding is secured to a window subframe and protects the latter from the elements and from condensed water which is discharged from the apertures in the moulding.

The invention may be better appreciated from the following description by way of example, with reference to Figures 1 and 2 of the accompanying drawings, of which: Figure 1 is an isometric view of a moulding in accordance with this invention, and Figure 2 illustrates the use of the moulding shown in Figure 1.

The moulding illustrated in Figure 1 comprises a channel like support 1 for the lower edge of a pane of glass and a channel 2 for collecting condensate from the interior of the pane (not shown). The two channels 1, 2 are formed with a common wall 3. One or more weep holes 4 are provided through the wall of the channel 3 below the support 1. These holes permit water to drain from the channel 2 to the'exterior of the window frame. A flange 5 facilitates fixture of the moulding to a window subframe. The flange may be provided with holes through which bolts, screws, rivets or the like may be secured. Any alternative means of fixture may be provided. The channel 2 is provided with a ridge 6 which ensures that the base of the channel 7 is inclined towards the hole or holes 4. A flange 8 prevents ingress of water along the surface of the flange 5.

The flange 8 may in some embodiments of the invention extend away from the main part 3 of the moulding to form a complete covering for the flange 5 and associated screws or other fixing means.

Figure 2 shows the mould of Figure 1 in use. A pane of glass 9 is located in the support 1. The support 1 has the shape of a channel, but any other convenient shape, for example with perforations, may be provided. The window frame is shown at 10. The moulding is secured to the frame 10 by means of screws 1 1 the heads of which are grouted with putty to prevent corrosion.

The flange 8 prevents water from penetrating between the putty and the flange 5.

It can be seen that the lower edge of a pane of glass 9 must be trimmed when an existing window frame 10 is modified but no other structural alterations in accordance with this invention are required.

Claims (filed on 7 Sept 1982) 1. A window frame moulding comprising a support for a pane of glass, a channel disposed adjacent one side of the support and one or more apertures communicating between said channel and another side of the support.
