Abstract

A glazing system for holding a glazing panel (6) in an outwardly facing rebate (4) comprises an external glazing bead (10) which has flanges (12, 14) which engage in corresponding grooves (16, 18) in the frame member. An internal wedge is provided partly of soft material and partly of hard material. The hard portion (32) engages between setting blocks (8) on which the glazing panel is seated and the upstanding surface (5) of the frame member defining the rebate. In this way the bead (10) is held, by means of its engagement with the setting blocks (8), in firm engagement with the frame member so that the bead cannot be removed from the exterior of the window. <IMAGE>

Description

GLAZING SYSTEM The present invention relates to glazing systems for fixing glazing panels to window frames which are of the type having an externally facing rebate.
Various proposals have been made for fixing glazing panels into an outwardly facing rebate of a glazing bar or frame member. Such systems typically use an extruded, relatively rigid glazing bead, which is applied externally once the glazing panel has been fitted, in order to hold the panel in place. While it is desirable to be able to remove this bead readily in order to replace the glazing panel, the use of an external bead reduces the security of the window since an intruder can remove the glazing panel from the outside.
In order to solve this problem, various systems have been proposed for connecting the glazing bead to the frame member so that it is difficult to remove from the exterior. Examples are GB-A-2 110 285 and GB-A-2 144 477. In both these systems the glazing bead is provided on its lower surface with projecting flanges, which engage in grooves formed in the frame member. The flanges can be fitted when the glazing panel is not present or pushed inwardly against an upstanding surface of the glazing bar defining the rebate. When the glazing panel is pushed outwardly towards the bead by means of an internal glazing wedge, these flanges are held in their corresponding grooves so that the bead cannot be removed until the wedge is removed and the glazing panel pushed inwardly again.The proposed internal wedge is made of soft plastics material because it is intended to provide a seal between the internal face of the glazing panel and the frame member. Because the wedge is soft, the bead can quite readily be forced out if it is subjected to a sharp impact.
The technical problem of providing a secure glazing system for frame members with an outwardly facing rebate therefore still remains.
The present invention accordingly provides a glazing system comprising an elongate frame member with an outwardly facing rebate adapted to receive an edge of a glazing panel, the frame member defining at least one longitudinally extending groove in a surface portion of the frame member, a glazing bead having at least one projecting flange adapted to engage with a said groove, an internal wedge adapted to seat between the frame member and the internal surface of a glazing panel, and a plurality of setting blocks adapted to be placed beneath the glazing panel in the base of the rebate, characterised in that the internal wedge comprises a soft sealing portion adapted to provide a seal between the face of the glazing panel and the internal face of the frame member, and a harder portion which extends towards the base of the rebate to engage with the setting block(s) beneath the glazing panel, in order to hold the block(s) in a position in engagement with a portion of the bead so that at least one flange of the bead is held against removal in its corresponding groove.
The use of the two-part internal glazing wedge positively prevents the glazing panel and setting blocks being moved inwardly in the rebate, so that it is not possible to remove the glazing bead from the outside, unless the internal wedge has first been removed. The use of a hard material for the portion of the wedge which engages the block prevents transmission of a force sufficient to eject the wedge from the exterior by application of a sharp impact to the glazing bead.
A glazing system in accordance with the present invention will now be described, by way of example only, with reference to the accompanying diagrammatic drawings, in which: Figure 1 is a cross-section through a frame member showing the system installed; and Figure 2 is a cross-section through the frame member for the purpose of explaining the glazing method used with the present system.
Figure 1 shows a cross-section through an elongate frame member 2 which is used to form a window frame. The frame member is an extruded section of aluminium or plastics material, for example uPVC. The frame member defines an outwardly facing rebate 4 with a base and an upstanding surface 5. The edge of a glazing panel 6 is received in the rebate and is supported at intervals on setting blocks 8, one of which is shown in cross-section in the drawings.
A glazing bead 10 defines with the frame member 2 a channel in which the edge of the glazing panel is fixedly held. The bead 10 may also be an elongate extrusion of aluminium or plastics material, e.g. uPVC.
The bead section includes two laterally projecting flanges 12, 14 on the surface which co-operates with the frame member. Each flange engages with a corresponding groove 16, 18 defined in the frame member 2. As illustrated, the groove 16 is an inwardly facing groove adjacent the external edge of the frame member 2. The groove 18 is defined inwardly of the groove 16 and is of relatively greater depth so that the flange 14 can slide into and out of the groove 18. when the bead is pushed inwardly so that the flange 14 is pressed against the base of its groove 18, the flange 12 is disengaged from the groove 16. This allows the bead to be inserted in the frame member when the glazing panel is not in position or pushed into abutment with the surface 5 of the rebate.A portion of the inner face 20 of the bead engages with setting blocks 8, where present, in the installed position shown in Figure 1. The inner face of the bead 10 is also provided with a slot 22 for receiving a retaining portion 24 of a resilient sealing gasket 26 which provides a weather-proof seal between the bead and the external face of the glazing panel 6.
A wedge 28 is provided between the internal surface of the glazing panel 6 and the upstanding surface 5 of the frame member 2. The wedge 28 comprises an upper portion 30 of a soft material which provides the seal between the face of the glazing panel and the frame member, and a portion 32 of a harder material which projects downwardly towards the base of the rebate and engages with the edge of the setting blocks 8, where present.
The harder portion 32 also includes a lateral projection 34 which engages in a slot 36 defined in the upstanding surface 5 of the frame member 2. The inter-engagement of the portion 34 and slot 36 resists too ready removal of the wedge 28 from the frame member from the interior.
From Figure 1 it will be seen that the engagement of the hard portion 32 of the wedge 28 with the setting block 8 holds the block and the glazing panel seated thereon in a position in which the blocks 8 engage the glazing bead 10, which is biased outwardly so that the flange 12 is firmly engaged in the groove 16. With the wedge in this position, the bead 10 cannot be removed from the exterior of the window. Removal can only take place after the wedge has been removed, allowing the setting blocks and glazing panel to be pushed inwardly towards the upstanding surface 5 of the rebate. This allows the glazing bead likewise to be slid inwardly freeing the flange 12 from the groove 16. Then the bead can be pivoted about the flange 14 to lift the flange 12 above the surface of the frame member, so that the complete bead can be removed by sliding outwardly. In order to assist the pivoting motion, a portion of the surface of the flange 14 which faces the upper part of the groove 18 is formed with an arcuate cross-section.
In order to install the glazing panel 6 a special tool 38 is required. The use of this tool is illustrated in Figure 2. The tool 38 has a portion 40 which engages in a corresponding recess 42 provided in the setting blocks 8. The glazing is installed in the usual manner, that is the setting blocks 8 are positioned in the base of the rebate, the bead 10 with its associated gasket 26 is installed in the frame member, and the glazing panel 6 positioned in the rebate on the setting blocks. Then a tool 38 is applied to each setting block in order to push it outwardly as shown by the arrow 44 until the outer face of the setting block engages with the surface 20 of the bead 10 and the projection 12 is firmly seated against the base of the groove 16. In order to produce this movement, the tool 38 is used as a lever with the upper edge of the upstanding surface of the rebate providing the fulcrum. With the setting blocks in the required position and the glazing panel shifted towards the exterior of its channel, the wedge 28 is inserted between the glazing panel and the frame member so that the end of the hard portion 32 is received between the setting blocks, where present, and the frame member in order to prevent the setting blocks moving inwardly.
while the wedge 28 is partially inserted the tools 38 may be removed to allow complete insertion of the portion 32 behind each setting block.
