United States Patent 3,343,859 CDNSTRUCTIGNAL ASSEMBLIES COWRISING TWO OR MORE BARS Jack Fox-Wiliiams, 3 Belgrave Place,
London SW. 1, England Filed May 7, 1965, Ser. No. 454,029 Claims priority, application Great Britain, May 8, 1964, 19,299/ 64 4 Claims. (Cl. 287-189.36)
ABSTRACT OF THE DISCLOSURE A construction of joint between two bars lying at an angle to one another in which each bar comprises at least two longitudinally extending main flanges which, seen in cross-section, lie at an angle to one another, wherein one main flange of tr e first bar is formed with at least one slot extending from the edge of the flange to the adjacent face of another main flange and serving to accommodate one of the main flanges of the second bar and permit the end of the second bar to abut against the said other main flange of the first bar, and wherein the second bar is provided on the inner face of at least one of its main flanges which at least one longitudinally extending subsidiary flange or rib forming with part of a flange of the second bar a longitudinally extending groove in which lies a part of the slotted flange of the first bar adjacent to a slot or adjacent to the end edge thereof.
This invention relates to constructional assemblies of the kind comprising at least two bars (herein referred to as first and second bars) lying at an agle to and usually but not necessarily, at right angles to one another and of the kind in which each bar comprises at least two longitudinal main flanges lying at an angle (usually but not necessarily at right angles) to one another when seen in cross section, one main flange of the first bar being formed with at least one slot extending from its edge to the plane of the adjacent face of the other main flange of the first bar to accommodate one of the main flanges of the second bar and permits the end edge of the first bar to abut against a surface of the other main flange of the second bar.
The term main flange used above is to be interpreted as including a part which in cross section extends between two flanges as for example the base of a trough-like bar and also as including any side of a bar or part of a bar of hollow cross section.
It is an object of the present invention to provide an improved assembly of the kind in question in which the assembly will tend to resist to a higher degree than hitherto relative angular movements between the two bars.
The invention is particularly but not exclusively applicable to constructional assemblies as used for the corners of metal window frames.
In a constructional assembly of the kind referred to according to the present invention the second bar is provided on the inner face of at least one of its main flanges one or more longitudinally extending subsidiary flanges or ribs, such subidiary flanges or each of such subsidiary flanges forming with part of a main flange of the second bar, a longitudinally extending groove in which lies a part of one of the flanges of the first bar adjacent to one side of the said slot therein or adjacent to the end edge of a slotted main flange thereof.
The invention is particularly applicable to construetions in which each of the two bars comprises at least two main flanges disposed in spaced parallel relationship and projecting from opposite edges of a third main flange Patented Sept. 26, 1967 and in this case the said second bar is preferably provided with subsidiary flanges which, in conjunction with each of said spaced parallel flanges form at least one longitudinally extending groove which receives a portion of a flange of said first bar adjacent to a slot in or constituting the end edge of such a flange.
In one such construction subsidiary flanges are provided on said second bar to provide grooves which lie adjacent respectively to adjacent opposite edge portions of each of said spaced parallel flanges, and in addition at least one groove at an intermediate point in the width of each of said spaced parallel flanges, one of said grooves adjacent to a lateral edge portion of each flange and said groove at an intermediate point in said flange serving to accommodate parts of a flange of the first bar adjacent respectively to slots therein while the third groove accommodates an end edge portion of said flange of said first bar.
One construction according to the invention as applied to the corner of a window frame is shown in the accompanying drawings in which,
FIGURE 1 is a cross section through one of the bars, constituting the said second bar,
FIGURE 2 is a cross section through the other bar, constituting the first bar,
FIGURE 3 is a side elevation of the parts of the two bars which are to be joined to form the corner of the frame before assembly,
FIGURE 4 shows the two parts shown in FIGURE 3 as they appear at an intermediate joint in the assembly operation,
FIGURE 5 shows the two parts fully assembled to form the corner of a window frame, and
FIGURE 6 is a cross section on the line 66 of FIG- URE 5.
A window constructed from bars joined at the corners of the window frame in the manner shown in the drawings, will comprise 4 bars forming a rectangular frame, the upper and lower horizontal bars being of the cross section shown in FIGURE 1 while the two vertical side bars are of the cross section shown in FIGURE 2.
Each of the horizontal bars, as shown most clearly in FIGURE 1 includes a part of rectangular cross section, comprising four sides, 1, 2, 3, 4 constituting main flanges and having internal longitudinally extending subsidiary flanges, 5 and 6 which project from the main flanges 2 and 4 respectively, and form, with adjacent parts of the flanges 2 and 4, grooves 7, and having also subsidiary flanges 8, which form with adjacent parts of the flanges, 2 and 4, grooves 9.
In addition, the bar shown in FIGURE 1 is provided with a channel formed by two further main flanges 10, which channel faces inwardly in the complete window frame to receive an edge portion of a panel or panels of glass or the like while the bar also has an outwardly projecting main flange 11, which, with the side 3, constitutes the part which will engage with the periphery of the fixed frame of the window, which may be assumed to fill an opening in a wall. Each flange 10, has an inturned bead 12 at its edge.
The terms inwardly and outwardly used herein refer to directions in the mid-plane of a panel or panels supported by the frame respectively towards and away from the centre of the area of the panel or panels.
Each of the vertical bars of the frame, as shown most clearly in FIGURE 2 comprises a base part 13 from which project inwardly two parallel flanges, 14, so spaced apart that their outer faces are separated by approximately the same distance as the inner faces of the sides 2 and 4 of the bar shown in FIGURE 1, the base 13 also having projecting outwardly from it flanges 15 and 16 for engagement with portions of the outer (fixed) frame of the window, which fixed frame as mentioned, may be assumed to be installed in an opening in a wall.
Formed in the flanges 14, as shown in FIGURES 2, 3, and 4 are slots 17, 18 and 19 which, in the assembled window accommodate respectively the beads 12, the subsidiary flanges 5 and 6 and the flange 1 of the rectangular portion of the bar shown in FIGURE 1. The distance between the slots 19 and the end edges 20 of the flanges 14 is approximately equal to the distances between the subsidiary flanges 5, 6 and the flange 3 of the rectangular portion of the bar shown in FIGURE 1.
Thus as will be seen from FIGURES 4, 5, and 6, the two bars can be assembled at right angles to one another in such a manner that the flange 1 of the bar shown in FIGURE 1 is accommodated in the slots 18 of the bar shown in FIGURE 2, the slots 19 accommodate the flanges, 5 and 6, and the slots 17 accommodate the beads 12, all in such a manner that the part of the flanges 14 between the slots 18 and 19 and between the slots 19 and the end edges 20 constitute in eifect spigots fitting between the main flanges 1, 2, 3 and 4 and the subsidiary flanges 5, 6 and 8 of the bar shown in FIGURE 1.
After the parts have been fully assembled as shown in FIGURE 5, parts of the sides 2 and 4 of the bar shown in FIGURE 1 may be distorted together with the adjacent parts of the flanges 14 so as to lock the parts permanently against separation.
What I claim as my invention and desire to secure by Letters Patent is:
1. A constructional assembly comprising at least two bars lying at an angle to one another and in which each bar comprises at least two longitudinally extending main flanges lying at an angle to one another when seen in cross section one main flange of the first bar being formed with at least one slot extending from its edge to the plane of the adjacent face of the other main flange of the first bar so as to accommodate one of the main flanges of the second bar and permit the end of the second bar to abut against a surface of the other main flange of the first bar, wherein the second bar is provided on the inner face of at least one of its main flanges with one or more longitudinally extending subsidiary flanges or ribs, such subsidiary flanges or each of such subsidiary flanges forming, with part of a main flange of the second bar, a longitudinally extending groove in which lies a part of the slotted flange of the first bar adjacent to one side of said slot therein or adjacent to the end edge thereof.
