Description

TITLE: Structural Frame Members
DESCRIPTION
This invention concerns structural frame members and is particularly concerned with structural frame members as mullions for supporting window
frames.
An object of this invention is to provide structural frame members for forming frameworks that can retain, for example, window frames or door frames.
According to this invention there is provided a structural frame member that has two parts connected by at least one collapsible part, whereby the two parts can be drawn towards each other to trap another item between spaced formations extending from sides of said parts, preferably to trap items on both sides of the frame member between spaced formations extending from both sides of said parts.
The two parts are preferably connected by a pair of collapsible webs and one part preferably has an end formation that fits within the other part when they are collapsed together, said parts overlapping to a certain extent, which preferably has a limit.
The spaced extending formations are preferably flanges and they may be flat or shaped. For items that have channel formations extending from their sides, the formations of the structural member may also be channel sections or other complementary formations to mate therewith. The flanges may be shaped for gripping, such as by having a serrated or otherwise uneven surface or may be L-shaped to fit into channel formations of the item to be trapped. Faces of the flanges for abutting window frames may be provided with sealing means.
Shaped slots along those faces may be provided to retain flexible sealing strips.
In a preferred embodiment of the invention, the structural frame member comprises a major part having side walls connected by a pair of spaced webs inwards from ends of the side walls and a minor part having side walls connected by a web, the two parts being connected by a pair of collapsible webs each between a pair of aligned sides of each part, whereby in an uncollapsed state items can be positioned against opposite sides of the member and in a collapsed state trapped between outwardly extending formations of the major and minor parts of the member.
Two parts of the structural member of the invention preferably each have means for retaining a cover strip for extending either side of the structural member to cover the joins with the trapped items. Preferably inner surfaces of the sides of the structural member have formations thereon, such as ribs or the like for retaining cooperating formations of said cover strips.
The cover strips may be single walled or more preferably are twin-walled especially forming multiple ducts for insulation purposes. Edges of the cover strips preferably retain gasket material or have coextruded gasket material therealong.
The structural frame members are particularly suitable for use on mullions in forming a framework to receive window frames. The framework preferably includes a base member and a top member, such as an eaves beam. For securing top and bottom members to the structural members, webs of the structural members are preferably formed with screw ports to receive screws through the top and bottom members respectively into the structural members.
To collapse a structural member of the invention to trap items, such as window frames therein, the two parts may be drawn together by means of screws through a web of one part into a web of the other part.
The invention further comprehends a glazed structure having a framework comprising structural members of the invention with window frames mounted therebetween and trapped along sides thereof between collapsed parts of said structural members.
The structural members used on the invention may be of any suitable material. Aluminium and uPVC are preferred materials, although in the case of uPVC strengthening members, such as of aluminum or steel may be required. Such strengthening members may be moulded into one or both parts of the structural member or may be shaped to fit channels or ducts therein.
This invention will now be further described by way of example only, with reference to the accompanying drawings in which:
Figure 1 is an end view of a first structural member according to the invention in uncoilapsed form;
Figure 2 shows the structural member of Figure 1 in collapsed form;
Figure 3 shows a first stage of connecting window frames to a structural member of Figure 1 and 2; Figure 4 shows a window frame connected to the structural member of
Figure 1 and 2;
Figure 5 shows a first variation on the structural member of Figure 1 ; and
Figure 6 shows a second variation on the structural member of Figure 1.
Referring to Figures 1 to 4 of the accompanying drawings, a structural frame member 10 comprises two parts 12, 14 connected by collapsible webs 16.
The first part 12 has sides 18 connected by webs 20, 22 spaced inwardly from ends of the sides 18. Outer ends 24 have extending outwardly L-shaped flanges
26 forming channels open oppositely to the ends. Internally of the ends 24 are notches 28. The outermost web 20 has a screw port 30 and the innermost web
22 a screw port 31.
Opposite ends 32 of the sides 18 are rebated at 34. Just prior to the rebates one end of each of the collapsible webs 16 is connected and the other ends of the collapsible webs are connected to ends of the side walls 36 of the second part 14 of the frame member 10.
The second part 14 has its side walls 36 connected by a web 38.
Outer ends of the side walls 36 have extending outwardly L-shaped flanges 42 that form channels open towards the flanges 26 of the first part 12 of the structural frame member. Inwardly of the ends of the side walls 36 are notches
44, inner ends of the side walls 36 are rebated on their outside to complement the rebates of the ends 32 of the sides 18 of the first part 12 of the member 10.
The member 10 is designed to be collapsed (as shown in Figure 2) to trap window frame sides 50 (see Figures 3 and 4) between respective pairs of flanges 26 and 42 on opposite sides of the member 10. Conveniently the window frame sides have L-shaped projections 52 that fit the channels formed by the flanges 26 and 42. The structural member 10 is collapsed by screwing through the web 38 of the second part 14 into the 22 of the second part to draw the webs towards each other. As that occurs the webs 16 collapse to trap the window frame sides between the pairs of flanges 26,42. Afterwards cover strips
56 are pressed into place on the end of the member 10 to cover the joins with the window frames. The cover strips 56 have a pair of projections 58 that are shaped at their ends to pass over the notches 28 or 44 of the structural member side walls and be retained by them. Along each side of the cover strips is coextruded gasket material for sealing against the window frames.
The frame members 10 are intended to be incorporated into a framework comprising an eaves beam and a bottom beam, each of which may be secured to the member 10 by means of screws therethrough into the screw ports 30 and 31.
Turning to Figure 5 of the accompanying drawings, a variation to the frame members 10 is shown for use with window frames or panels that have no recess for the L-shaped flanges 26. Instead flanges 26' are straight and have T- section slots 68 along their inner faces to receive sealing strips 70. Then, when the frame members of Figure 5 are collapsed to capture a window frame, the flanges 26' grip and seal against the window frames.
The variation of Figure 6 has stepped flanges 26" to close against window frames as the frame member is collapsed. Sealing against the window frames is provided by decorative cover strips 56', that are held in place not only in the same way as the cover strips 56 of the main embodiment but also by means of edges 80 that clip fit over stepped ends 82 of the flanges, and that have co- extruded or bonded flexible seals 84 along edges thereof to be compressed against the window frames.
An advantage of the frame members of the invention is that the window frames can be installed pre-glazed because no fixings have to be used through the window frame sides into the structural frame members.
