- 1 denotes a metal component exhibiting box section and affording a recess in which a plug of given appropriate shape and dimensions, preferably quadrangular, may be inserted.
- the component 1 exhibits a substantially rectangular cross section, in which the sides of the box profile are denoted 2, 3, 4 and 5; two of the sides 4 and 5 are run out into extensions 41 and 51 terminating at a given point in respective lips 6 and ich are bent inwards and disposed parallel to the transverse side 3 of the box.

Abstract
Description
- The invention relates to a new method of embodying composite metal window and/or door frame members that incorporate two sections, one exposed to the external environment, the other facing indoors, interconnected in a rigid fit by way of one or more plugs fashioned from a heat-insulating material. In the composite assembly thus created, one prevents any transfer of heat from taking place between the two component sections separated by the plug. Prior art methods adopted hitherto in the attempt to achieve this end-result have consisted in utilizing chemical substances or other means to preassemble the two component sections prior to their leaving the factory.
- Composite metal frame members have also been made which consist in two or more components united by the insertion of longitudinal jointing sections or lengths of heat-insulating material; assembly of such a composite member often involves additional extruding and bending operations, and at all events, a firm and durable joint cannot be guaranteed. The consequent drawbacks of such an assembly system are serious, and obvious.
- Accordingly, the main object of the invention is to provide a special method of assembling two component sections, one exposed to the external environment, the other to the internal, which can be performed by hand simply locating one or more special bridging plugs, fashioned from PVC or another heat-insulating material, between the two.
- The method disclosed permits of embodying metal door and window frame members having the same features as those currently manufactured and distributed in a preassembled package with heat-insulation barrier already built in, but at lower cost. Thus, one can obtain the same end-result utilizing commonplace extruded sections in aluminium or other metal, but delaying embodiment of the heat-insulation barrier until the moment that these are joined together by way of the plugs.
- An additional object of the invention is that of providing a method whereby metal component sections and plugs can be fitted together simply by locating and snapping into place, affording a rigid, durable assembly and avoiding further mechanical operations.
- The stated objects are achieved by adoption of a composite metal frame member as characterized in the appended claims, incorporating two metal component sections and a non-metallic bridging plug.
- The invention will now be described in detail, by way of example, with the aid of the acompanying drawings, in which:
- fig 1 is the section through a first metal component according to the invention;
- fig.2 is the similar section through a second metal component according to the invention, designed to pair with the first component of fig 1;
- fig 3 shows the same section through an alternative embodiment of the second component of fig 2;
- fig 4 shows the front elevation and the plan of a bridging plug according to the invention;
- fig 5 is a side elevation of the plug in fig 4;
- fig 6 is a cross section through the plug of fig 4;
- fig 7 is a section through the composite assembly of component sections and bridging plug, according to the invention.
- With reference to fig 1 of the drawings, 1 denotes a metal component exhibiting box section and affording a recess in which a plug of given appropriate shape and dimensions, preferably quadrangular, may be inserted.
- The component 1 exhibits a substantially rectangular cross section, in which the sides of the box profile are denoted 2, 3, 4 and 5; two of the sides 4 and 5 are run out into
extensions respective lips 6 and ich are bent inwards and disposed parallel to thetransverse side 3 of the box. - 101 denotes the recess thus encompassed by 6, 7, 41, 51 and 3, which serves to accommodate a bridging plug according to the invention (see figs 4, 5 & 6).
- 8 denotes a second component section (see fig 2) designed to pair with the first section 1, which in the example illustrated appears trapezoidal, having a base 9, and similarly angled
sides 10 and 11. - The one angled side 11 terminates in a
lip 12 that is bent back parallel with the base side 9, whereas thecorresponding lip 13 at the end of the remainingangled side 10 is extended and bent back further in the direction of the base through a stretch 14 that lies parallel with the self-same side 10. - 15 denotes a rib issuing from the base side 9, which is disposed parallel with the
angled side 10 and in alignment with the stretch 14 bent upward from therelative lip 13. - A further rib 16 departs from the base side 9 at a point approximately half way along its length, in this instance extending parallel with and through an identical distance to the
angled side 10. - The rib 16 terminates in two lips, one of which, denoted 17, is bent back toward the first mentioned angled side 11 and exhibits identical geometry to the
relative lip 12, whereas the other, denoted 18, is bent inward at an angle of 45° in the opposite direction, i.e. toward the remainingangled side 10. - 19 denotes a further rib which departs from the main central rib 16 and extends toward the
angled side 10 and the open side of the trapezium, terminating in arespective lip 20 that is bent back toward the lip denoted 18. It will be observed in fig 2 that these twolips 18 and 20 also exhibit matching geometry. Thus embodied, thesecond component section 8 offers a substantially three-sidedtrapezoidal recess 108, encompassed by 9, 11, 12, 16 and 17, that combines with thequandrangular recess 101 of the component 1 described above in accommodating a bridging plug, embodied according to the invention, by means of which the assembly is rendered a stable, composite member. - In fig 3 of the drawings, 81 denotes an alternative embodiment of the
second component section 8 which affords atrapezoidal recess 118 exhibiting the same effective dimensions as that denoted 108, though encompassed laterally only in part; in this instance twoshort ribs 21 and 22 replace the full-length sides. - Figs 4, 5 and 6 show elevations and a sectional view of the bridging plug disclosed, which is fashioned from a heat-insulating material such as PVC. It will be observed from the front elevation (fig 4) that the plug exhibits a
main centre piece 23 and is of essentially, though not perfectly rectangular shape. The departure from perfect rectangularity consists in the fact that thetop side 24 is broken by twoslots 25, one at either end, right and left; thus one has twoend pieces 26 separated in part from thecentre piece 23, but joined thereto by the base 27 which is common to all three. - It is an essential feature of the
end pieces 26 that they appear shorter than the correspondingparallel ends 124 of thecentre piece 23. - Fig 5 shows a side elevation of the bridging plug, which illustrates the proportions of the
end piece 26, and the profile of the base and top part. It will be observed from the elevation of fig 5 and the cross section of fig 6 that the plug exhibits abase 28 the shape of which is, if not absolutely rectangular, at all events quadrangular, in order to permit of its being forced lengthwise and fitting snugly into therecess 101 of the first component section 1. Needless to say, the ultimate sectional profile of therecess 101 and thebase 28 of the plug is a matter of choice, dependent simply on the fact of the one matching the other. - Each
end piece 26 comprises a pair of identical and symmetrically disposedtongues 29 that are separat y agap 30, exhibiting the outline of a trapezium with the smaller base 31 at bottom, which opens out internally into therelative slot 25. - The tongues are possessed of outer surfaces which converge upwards from a given point, presenting a tapered profile; more exactly, the
tapering stretch 32 of each surface is separated from thebase 28 by anundercut 33 the position of which corresponds to that of asimilar undercut 133 running the entire length of thecentre piece 23, at either side. - The cross section of fig 6, taken through the A-B cutting plane marked in fig 4, shows the composition of the top part of the plug profile, in which the tapered part of the
centre piece 23 is matched to thetrapezoidal recess end pieces 26 shows slightly proud at either side, by reason of the tapering stretches 32 being set at a wider angle, and remains marginally short at the top. - Fig 7 shows the first component section 1 and the
second component section 8 fitted together by way of the bridging plug, with thebase 28 accommodated and held fast by thequadrangular recess 101, and the tapered part of thecentre piece 23 seated in thetrapezoidal recess 108. Rigidity is imparted to the composite assembly by the snap fit between the twotongues 29, which are rendered flexible thanks to thegap 30 provided between them, and thelips 12 and 17 offered by thesecond component section 8. - The
