Description
1222~6~ 23724-115 The invention relates to a composite heat-insulating section, more particularly for window-frames or door-frames, consisting of two profiled metal bars or frame members united by an insulating element, the said profiled metal bars comprising, on both longitudinal sides of the insulating element, continuous strips engaging in recesses in the said insulating element; an intermediate web, engaging in a groove in the said insulating element, being provided on each profiled bar between the said continuous strips, the said webs running at an angle to the said continuous strips on one longitudinal side of the said insulating element, and the width of the said grooves being greater than the thickness of the said intermediate webs and the continuous strips towards which the intermediate webs are directed, the strips being deformed by pressure from the outside whereby to press the insulating element onto the profiled metal frame members in the area between the intermediate webs and the continuous strips and provide the insulating element on a side facing away from the intermediate webs with edge strips.
A composite heat-insulating section of this kind is known (German OS 29.11 832), in which the lower part of the insulating element is held by appropriate positive guides to the relevant profiled metal sections. It has been found, however, in practice that where production-tolerances or production-inaccuracies arise, especially in the case of the grooves let into the insulating element for the accommodation of corresponding webs in the profiled metal bars, the lower parts of the said bars, i.e. the parts acted upon by the positive guides, are not lZZ2~6S
adequately held by the said insulating element. This leads to composite sections which lack dimensional stability and in which the profiled metal bars are not parallel with each other.
It is the purpose of the invention to provide a composite heat-insulating section, of the type mentioned at the beginning hereof, in such a manner as to ensure positional stability of the profiled metal bars and insulating element, in spite of production-tolerances and production-inaccuracies in the components constituting the section.
According to the invention, this purpose is achieved in that each edge strip engages in a pick-up groove of each profiled metal frame member equipped with a pivotable and cold-formable inner web, that an inner web forms an inner wall of the pick-up groove and is pivotable about an axis running parallel to the longitudinal direction of the associated profiled metal frame member, that there is a gap between the bottom of the pick-up groove and an end strip and that the end strip is clamped between the inner web and the inner wall of the profiled metal frame member.
According to one advantageous example of embodiment of the invention, edge-strips, provided in the corner-areas of the insulating element, bear with their lateral boundary surfaces, frictionally against the inner walls of the profiled metal frame members (or bars).
: This produces, in the four corner-areas of the insulating element, reliable bracing between the said elements and the said bars, thus compensating for production-tolerances and production-!- i,' "` ~LZ'~ 65 inaccuracies in the components constituting the section.
Vertical bracing between the profiled metal frame members and the insulating element is effected by means of non-deformable intermediate webs, engaging in grooves in the insulating element, and continuous deformable strips on the profiled metal frame members. Since only the continuous strips running along the insides of the profiled metal frame members are deformed, the visual surfaces of the profiled metal frame members are held parallel with each other. Vertical displacement is also prevented.
For the purpose of increasing the insulating effect, while still retaining a highly stable insulating element, two or four cavities, serving as air-chambers, are preferably provided within the said insulating element.
The invention also covers a method for producing a heat-insulating composite section consisting of two-spaced-apart profiled metal frame members united by a spacing insulating element, the said profiled frame members comprising on both longitudinal sides of the insulating element, continuous inwardly directed strips engaging in recesses at the top and bottom of the insulating element; an inwardly directed intermediate web, engag-ing in a groove in the said insulating element, being provided on each profiled frame member between the said continuous strips, the said intermediate webs running at an angle to the continuous strips and the width of the grooves being greater than the thickness of the intermediate webs and the continuous strips towards which the intermediate webs are directed, the strips being deformed by pressure from the outside whereby to press the ,~ .
.iZ2Z~65 23724-115 insulating element onto the profiled metal frame members in the area between the intermediate webs and the continuous strips and providing the insulating element on a side facing away from the intermediate webs with edge strips, characterized in that each edge strip engages in a pick-up groove of each profiled metal frame member equipped with a pivotable and cold-formable inner web, that an inner web forms an inner wall of the pick-up groove and is pivotable about an axis running parallel to the longitudinal direction of the associated profiled metal frame member, that there is a gap between the bottom of the pick-up groove and an end strip and that the end strip i5 clamped between the inner web and the inner wall of the profiled metal frame member, which method is characterized in that the insulating element is pushed into the continuous strips and pick-up grooves of the profiled metal frame members, and onto the lateralintermediate webs on the said frame members and in that, subsequentially,pressure is applied, from the outside, by means of pressure applying means to the top continuous strips whereby the said top continuous strips are pressed obliquely and downwardly into the insulating element, while the bottom continuous strips are pressed upwardly into a correspnding horizontal position into the said insulating element and the edge-strips are pressed against the said profile metal frame members in such a manner that the said insulating element is caused to bear frictionally against the said frame members in all areas of contact.
This produces a strongconnection between the insulating element and the profiled metal bars and maintains an accurate ,:
~ - 3a -"`-`' 1~;22~65 overall sectional depth. The components constituting the composite section are clamped together both vertically and horizontally, even major production tolerances being compensated for by the play existing initially between the said components.
Examples of embodiment of the composite section according to the invention are illustrated in the drawings attached hereto and are explained hereinafter. In the said drawings:
Figure 1 is a cross-section through a composite section in the not completely assembled condition;
Figure 2 shows the composite section according to Figure 1 in the completely assembled condition;
Figure 3 is a modification of the design according to Figures 1and 2;
Figure 4 shows cross-sections of a casement-frame and window-frame made from the composite section according to the inventlon .
The composite sectionconsists of profiled metal bars 1, 2; 1a, 2a and a profiled, dimensionally stable insulating element 3 made of synthetic material. The insulating element in the example according to Figures 1 and 2 - 3b -~,, ~,"
" lZ2216S
contains four cavities 4 designed as air-chambers, the webs between the said cavities being designed as diagonals S of the said insulating element.
In the example of embodiment according to Figure 4, the insulating element is equipped with two cavities 4.
The profiled metal bars (or frame members) comprise, near their upper ends and externally of the insulating element uniting them, continuous strips 6, 7 which initially extend horizontally, the under surface of each strip carrying a cam-like surface 8 associated with a corresponding recess 9 in the said insulating element. In addition to this, the sides of the insulating element facing the profiled metal bars are provided with grooves 10, 11 directed obliquely upwardly into the interior of the element, into each of which an intermediate web 12, 13, projecting from the said metal bars, projects. The width of oblique grooves 10, 11 is substantially greater than the thickness of intermediate webs 12, 13. Each of the said webs carries, at the transition between it and the profiled metal bar, a continuous groove 14 into which the tip of edge-strip 15 of the insulating element projects. The said insulating element also comprises a nose 16 projecting centrally from its under-surface, the said nose serving as a stop for the window-frame when the composite section is used as a casement frame.
In the example of the embodiment according to Figures l and 2, a lower hooked strip 17, 18 is fitted to each profiled metal bar 1, 2 facing upper strip 6, 7. Even in the unbraced condition shown in Figure l, each strip 17, 18 engages in a corresponding groove l9 in insulating element 3. Web 20 of strip 17, 18 is inclined downwardly, at an angle of about 10, in relation to transverse plane 21 of the said bars, whereas the angle between the inside of hook 22 on strip 17, 18 and plane 23 running parallel with the bars is about 20 The angle between the lateral walls of groove 19 and parallel plane 23 is accordingly also about 20. The transition from the inside of hook 22 andthe inside of web 20 of strip 17, 18, and the transition from the lateral wall of groove 19 nearest to the relevant profiled metal bar to the under-surface of insulating element 3, are both rounded, as are the transitions from the bottom of the groove to the lateral walls thereof. The transition from the upper surface of hook 22 on strip 17, 18 to its rear surface is also rounded, as is the transition from the outside of web 20 to the relevant profiled bar.
The thickness of hook 22 corresponds to the thickness of web 20 of the said strip. A continuous groove 24, serving as a predetermined bending location, is let into the inside of web 20 at the junction with the relevant profiled metal bar. The end of hook 22 on strip 17, 18, which engages in the lateral wall of groove l9, is pointed.
In producing the composite section according to Figures 1 and 2, upper strips 6, 7 are pressed down, preferably by rollers, pressure-slides, or the like, simultaneously or consecutively, from the horizontal position shown in Figure 1, so that, on the one hand, cam-like surfaces 8 engage with recesses 9 in insulating element 3 which has been pushed into place and, on the other hand, lower hooked strips 17, 18 are pressed upwardly, again preferably by rollers or the like, from their downwardly inclined position, into an approxi-mately horizontal position, whereby hooks 22 on the said strips press the said insulating element firmly against the relevant inner walls 26 of profiled metal bars 1, 2~
As strips 6, 7 are bent from the position shown in Figure 1 into the position shown in Figure 2, the said strips pivot about axes A, whereas hooked strips 17, 18 pivot about axes B. Lateral boundary surfaces 15a, 25a of edge-strips 15, 25 on insulating element 3 are caused to bear frictionally, in the terminal position shown in Figure 2, against inner walls 26 of the profiled _ 5 -` ~A"
i2;~2~6S
metal bars.
As a result of the bending of strips 6, 7, insulating element 3 is also pressed firmly onto intermediate webs 12, 13~ thus producing a positive engagement in addition to the frictional engagement, resulting in a permanent, immutable joint between the components of the composite section.
In place of hooked strips 17, 18, the example of embodiment accord-ing to Figure 3 comprises webs 30 which are cold-formable, are adapted to pivot about an axis B, and define an internal pick-up groove 28. An edge-strip 25 on insulating element 3 is inserted in the said groove. The initial position of web 30 is shown in Figure 3 in full lines, while the terminal position is shown in dotted lines.
The free end of web 30 comprises, on the side facing edge-strip 25, a projecting cam-like surface 27.
The bottom 29 of pick-up groove 28 extends at right angles to inner wall 26 of profiled metal bar 2. Even after web 30 has been bent, a gap remains between edge-strip 25 and the bottom of the said groove.
The forces whereby edge-strips 25 and 15 are pressed against inner walls 26 of the profiled metal bars are indicated by arrows F.
A composite heat-insulating section of this kind is known (German OS 29.11 832), in which the lower part of the insulating element is held by appropriate positive guides to the relevant profiled metal sections. It has been found, however, in practice that where production-tolerances or production-inaccuracies arise, especially in the case of the grooves let into the insulating element for the accommodation of corresponding webs in the profiled metal bars, the lower parts of the said bars, i.e. the parts acted upon by the positive guides, are not lZZ2~6S
adequately held by the said insulating element. This leads to composite sections which lack dimensional stability and in which the profiled metal bars are not parallel with each other.
It is the purpose of the invention to provide a composite heat-insulating section, of the type mentioned at the beginning hereof, in such a manner as to ensure positional stability of the profiled metal bars and insulating element, in spite of production-tolerances and production-inaccuracies in the components constituting the section.
According to the invention, this purpose is achieved in that each edge strip engages in a pick-up groove of each profiled metal frame member equipped with a pivotable and cold-formable inner web, that an inner web forms an inner wall of the pick-up groove and is pivotable about an axis running parallel to the longitudinal direction of the associated profiled metal frame member, that there is a gap between the bottom of the pick-up groove and an end strip and that the end strip is clamped between the inner web and the inner wall of the profiled metal frame member.
According to one advantageous example of embodiment of the invention, edge-strips, provided in the corner-areas of the insulating element, bear with their lateral boundary surfaces, frictionally against the inner walls of the profiled metal frame members (or bars).
: This produces, in the four corner-areas of the insulating element, reliable bracing between the said elements and the said bars, thus compensating for production-tolerances and production-!- i,' "` ~LZ'~ 65 inaccuracies in the components constituting the section.
Vertical bracing between the profiled metal frame members and the insulating element is effected by means of non-deformable intermediate webs, engaging in grooves in the insulating element, and continuous deformable strips on the profiled metal frame members. Since only the continuous strips running along the insides of the profiled metal frame members are deformed, the visual surfaces of the profiled metal frame members are held parallel with each other. Vertical displacement is also prevented.
For the purpose of increasing the insulating effect, while still retaining a highly stable insulating element, two or four cavities, serving as air-chambers, are preferably provided within the said insulating element.
The invention also covers a method for producing a heat-insulating composite section consisting of two-spaced-apart profiled metal frame members united by a spacing insulating element, the said profiled frame members comprising on both longitudinal sides of the insulating element, continuous inwardly directed strips engaging in recesses at the top and bottom of the insulating element; an inwardly directed intermediate web, engag-ing in a groove in the said insulating element, being provided on each profiled frame member between the said continuous strips, the said intermediate webs running at an angle to the continuous strips and the width of the grooves being greater than the thickness of the intermediate webs and the continuous strips towards which the intermediate webs are directed, the strips being deformed by pressure from the outside whereby to press the ,~ .

This produces a strongconnection between the insulating element and the profiled metal bars and maintains an accurate ,:
~ - 3a -"`-`' 1~;22~65 overall sectional depth. The components constituting the composite section are clamped together both vertically and horizontally, even major production tolerances being compensated for by the play existing initially between the said components.
Examples of embodiment of the composite section according to the invention are illustrated in the drawings attached hereto and are explained hereinafter. In the said drawings:
Figure 1 is a cross-section through a composite section in the not completely assembled condition;
Figure 2 shows the composite section according to Figure 1 in the completely assembled condition;
Figure 3 is a modification of the design according to Figures 1and 2;
Figure 4 shows cross-sections of a casement-frame and window-frame made from the composite section according to the inventlon .
The composite sectionconsists of profiled metal bars 1, 2; 1a, 2a and a profiled, dimensionally stable insulating element 3 made of synthetic material. The insulating element in the example according to Figures 1 and 2 - 3b -~,, ~,"
" lZ2216S
contains four cavities 4 designed as air-chambers, the webs between the said cavities being designed as diagonals S of the said insulating element.
In the example of embodiment according to Figure 4, the insulating element is equipped with two cavities 4.
The profiled metal bars (or frame members) comprise, near their upper ends and externally of the insulating element uniting them, continuous strips 6, 7 which initially extend horizontally, the under surface of each strip carrying a cam-like surface 8 associated with a corresponding recess 9 in the said insulating element. In addition to this, the sides of the insulating element facing the profiled metal bars are provided with grooves 10, 11 directed obliquely upwardly into the interior of the element, into each of which an intermediate web 12, 13, projecting from the said metal bars, projects. The width of oblique grooves 10, 11 is substantially greater than the thickness of intermediate webs 12, 13. Each of the said webs carries, at the transition between it and the profiled metal bar, a continuous groove 14 into which the tip of edge-strip 15 of the insulating element projects. The said insulating element also comprises a nose 16 projecting centrally from its under-surface, the said nose serving as a stop for the window-frame when the composite section is used as a casement frame.
In the example of the embodiment according to Figures l and 2, a lower hooked strip 17, 18 is fitted to each profiled metal bar 1, 2 facing upper strip 6, 7. Even in the unbraced condition shown in Figure l, each strip 17, 18 engages in a corresponding groove l9 in insulating element 3. Web 20 of strip 17, 18 is inclined downwardly, at an angle of about 10, in relation to transverse plane 21 of the said bars, whereas the angle between the inside of hook 22 on strip 17, 18 and plane 23 running parallel with the bars is about 20 The angle between the lateral walls of groove 19 and parallel plane 23 is accordingly also about 20. The transition from the inside of hook 22 andthe inside of web 20 of strip 17, 18, and the transition from the lateral wall of groove 19 nearest to the relevant profiled metal bar to the under-surface of insulating element 3, are both rounded, as are the transitions from the bottom of the groove to the lateral walls thereof. The transition from the upper surface of hook 22 on strip 17, 18 to its rear surface is also rounded, as is the transition from the outside of web 20 to the relevant profiled bar.
The thickness of hook 22 corresponds to the thickness of web 20 of the said strip. A continuous groove 24, serving as a predetermined bending location, is let into the inside of web 20 at the junction with the relevant profiled metal bar. The end of hook 22 on strip 17, 18, which engages in the lateral wall of groove l9, is pointed.
In producing the composite section according to Figures 1 and 2, upper strips 6, 7 are pressed down, preferably by rollers, pressure-slides, or the like, simultaneously or consecutively, from the horizontal position shown in Figure 1, so that, on the one hand, cam-like surfaces 8 engage with recesses 9 in insulating element 3 which has been pushed into place and, on the other hand, lower hooked strips 17, 18 are pressed upwardly, again preferably by rollers or the like, from their downwardly inclined position, into an approxi-mately horizontal position, whereby hooks 22 on the said strips press the said insulating element firmly against the relevant inner walls 26 of profiled metal bars 1, 2~
As strips 6, 7 are bent from the position shown in Figure 1 into the position shown in Figure 2, the said strips pivot about axes A, whereas hooked strips 17, 18 pivot about axes B. Lateral boundary surfaces 15a, 25a of edge-strips 15, 25 on insulating element 3 are caused to bear frictionally, in the terminal position shown in Figure 2, against inner walls 26 of the profiled _ 5 -` ~A"

metal bars.
As a result of the bending of strips 6, 7, insulating element 3 is also pressed firmly onto intermediate webs 12, 13~ thus producing a positive engagement in addition to the frictional engagement, resulting in a permanent, immutable joint between the components of the composite section.
In place of hooked strips 17, 18, the example of embodiment accord-ing to Figure 3 comprises webs 30 which are cold-formable, are adapted to pivot about an axis B, and define an internal pick-up groove 28. An edge-strip 25 on insulating element 3 is inserted in the said groove. The initial position of web 30 is shown in Figure 3 in full lines, while the terminal position is shown in dotted lines.
The free end of web 30 comprises, on the side facing edge-strip 25, a projecting cam-like surface 27.
The bottom 29 of pick-up groove 28 extends at right angles to inner wall 26 of profiled metal bar 2. Even after web 30 has been bent, a gap remains between edge-strip 25 and the bottom of the said groove.
The forces whereby edge-strips 25 and 15 are pressed against inner walls 26 of the profiled metal bars are indicated by arrows F.
