Abstract

ABSTRACT

This invention relates to a multiple glazing assembly of the type made from metal extrusions such as aluminum. A pair of main frame members are connected by insulating members arranged to separate the frame members to provide a thermal break and also to give a triple seal to prevent air entering between the panes of the glazing.
The frame members are shaped and the insulating members are arranged so that a pair of such insulating members resists movement in one direction transverse to the axes of the metal extrusions. The third insulating member resists movement in a direction different to such one direction so that the insulating members combine to lock the metal extrusions against relative movement otherwise than an axial direction.
A resilient tube is particularly suitable for use as the third insulating member. The connection thus provided has the further advantage of flexibility to withstand impacts and deviations from linearity of the metal extrusions.

Description

~(~98~67 This invention relates to an assembly of extruded metal sections to provide a frame suitable for double glazing.
Extruded metal sections, particularly of aluminum, have commonly been used in double glazed windows or doors.
These have created a problem in that the high conductivity of the aluminum or other metal makes it desirable to provide a thermal break to avoid unnecessary heat loss.
Another problem is that the perfect sealing of a double glazing unit is difficult to achieve. Because of the range of ambient temperatures, the air between the panes expands and contracts, creating a pressure difference which will cause the penetration of moisture and consequent frosting if there has been the slightest damage to the seal during transport or erection.
A further problem is that some flexibility in the connection between the extrusions is sometimes desirable where the frame is to be shaped to follow a curved contour or even where the building structure to which the frame is to be affixed is not accurately linear.
It is therefore an object of this invention to provide a double glazing assembly of extruded sections separated by a thermal barrier.
A further object is to provide insulating connections which will lock the extruded sections together against relative movement other than axial movement but which will permit some flexibility, so that minor impacts during transportation and erection will not cause breakage of the seal, and to accommodate deviations from linearity of the extrusion when it is assembled.
Another object is to provide a tortuous passage for air seeking to enter between the panes of a multiple glazing unit and a triple seal to prevent the passage of air along such passage.

1(~9~767 Another object is to provide convenience of assembly.
These objectives are accomplished in accordance with one aspect of this invention by providing in a multiple glazing assembly adapted to receive glazing disposed in a vertical plane and having a respective outwardly facing and an inwardly facing surface and in which directional statements correspond with the aforesaid outwardly and inwardly facing surfaces, an outer : main frame member of extruded metal having an inwardly facing 10 groove and an inwardly facing projection inwardly spaced from said groove, an inner main frame member of extruded metal having an outwardly facing groove and an outwardly facing projection outwardly spaced from the last mentioned groove, a respective insulating insert within each of said grooves, the insert within each groove being engaged by the projection forming part of the other frame member so as both thermally to insulate said frame members from each other and to prevent substantial vertical movement of the frame members relative to each other, face-to-face recesses in said frame members located between the projection and groove of each frame member and a resilient insulating member keying in said face-to-face recesses to prevent excessive horizontal movement in an outward or inward direction of the frame members relative to each other, while permitting some flexibility of movement in - the last mentioned directions.
In accordance with another aspect of this invention there is provided an assembly of extruded metal sections and insulating members suitable for a window frame adapted to receive glazing disposed in a vertical plane and have a res-pective outwardly facing and inwardly facing surface and inwhich 1irectional statements correspond with the aforesaid outwardly and inwardly facing surfaces, comprising inner and 109~767 outer extruded metal sections, each of said sections including means to receive glazing and means for securing the assembly in position characterized in that a pair of spaced insulating members extend substantially parallel to the axes of said inner and outer extruded metal sections to provide a thermal barrier between said extruded metal sections, said spaced insulating members each keying the inner and outer - 2a -,,' sxtruded metal sections to resist movement in one direction transverse to the axes of the extruded metal sections and an additional insulating member extending substantially parallel to the axes of said inner and outer extruded metal sections providing a further thermal barrier therebetween and keying the mating inner and outer extruded metal sections to resist movement in a second direction transverse to the axes of the extruded metal sections different from said one direction, so that the spaced insulating members and the additional insulating member combine to resist relative movement of the extruded metal sections in any direction other than axial.
A further aspect of t~is invention includes an assembly of extruded metal sections suitable for the frame for double glazing comprising inner and outer extruded metal sections shaped and arranged to have portions which overlap each other, insulating means to space the extruded metal sections from each other and to prevent the overlapped portions moving away from or towards each other, opposed arcuate recesses in the overlapped portions and a tube of resilient insulating - material engaging the arcuate recesses to combine with the insulating means to resist either of said extruded metal sections moving relative to the other, except axially, while providing flexibility in the connections between the extruded metal sections.
This invention also provides a method of assembling an assembly as described in the preceding paragraph in which the U-shaped insulating means is fitted into position in its respective extruded metal section, the metal sections are brought together with a portion of each extruded metal section engaging the U-shaped insulating means of the other and the tube of resilient insulating material is inserted axially to ~09~3767 engage the opposed arcuate recesses and lock the assembly together.
In the drawings which illustrate the preferred embodiments of this invention:
Figure 1 is a plan view of an assembly in accordance with this invention;
Figure 2 is an endsectional view of an assembly in accordance with this invention;
Figure 3 is a perspective view of an assembly in accordance with this invention;
The assembly illustrated in Figure 2 comprises an inner main frame member of extruded metal such as aluminum 10 and an outer extruded aluminum main frame member 11.
Inner frame member 10 comprises a main body portion which supports a pair of spaced upstanding flanges 13 and 14 which receive the pane 15. Lateral projections 16 and 17 may be provided to seat separate securing plate 18 which is fastened to inner frame member 10 by screws 19. Inner frame member 10 also includes a dependent portion 20 having an undercut groove 21 to receive U-shaped insulating insert 22.
Inner frame member 10 has an outwardly extending projection 23 which fits within a second U-shaped insulating member 24 which is similar to U-shaped insulating member 22 except that it faces inwardly and is seated in outer frame member 11.
Inner frame member 10 also has a downwardly facing arcuate recess 25, the purpose of which will be described subsequently.
Outer frame member 11 has a main body portion 26 which has an upwardly facing arcuate recess 27, connected to a dependent flange 28 which is in turn joined to a horizontal section. Horizontal section 29 supports upstanding flanges 30 and 31 to receive pane 32. An inward extension of section 29 together with the upper surface of section 26 provide an undercut groove 33 to seat inwardly facing U-shaped insert 24.
Section 26 has an inwardly directed projection 34 to engage ~9~1~67 U-shaped insert 22.
It will be apparent from the foregoing that the engagement of projections 23 and 34 with U-shaped inserts 24 and 22 respectively act to space the extruded metal sections 10 and 11 from each other and provide a thermal barrier against the passage of heat from outside to inside or vice-versa. They also provide seals to prevent the flow of air into the space 34 between panes 15 and 32. Yet another function of U-shaped inserts 22 and 24 is to prevent relative movement between extrusions 10 and 11 in a vertical direction (in the orientation of Figure 2) while permitting axial movement and horizontal movement in a direction towards the inside or outside.
A tubular insulating member 35 which is preferably a split tube of resilient polyvinyl chloride, is inserted in recesses 25 and 27 to key extrusions 10 and 11 together to limit inward and outward relative movement to that permitted by deformation of the split tube 35. The U-shaped insulating members22 and 24 combine with tube 35 to lock the inner and outer main frame members 10 and 11 together. The tube prevents horizontal separation in an inward or outward direction, the U-shaped insulating members 22 and 24 prevent vertical separation (in the orientation of Figure 2).
Assembly of the extruded components illustrated in Figure 2 is easy. The U-shaped insulating members 22 and 24 are fitted into position in their respective extruded metal sections. Sections 10 and 11 are then brought into mating position with projections23 and 34 engaging the U-shaped insulating members. Then the tube of resilient insulating 30 material 35 is inserted axially between recesses 25 and 27 to lock the assembly together.

~39~7~'7 The preferred embodiment of the invention is a unitary window where the entire window frame is formed from an assembly such as that described. In one method of forming this assembly, the U-shaped insulating members are assembled, with projections 23 and 24 in mating position with sections 10 and 11, and the resilient insulating material 35 is inserted in its final position.
Then, the extruded members are bent longitudinally to form the corners of the window, and the glazing is inserted, following which the two ends of the extruded members are joined as at 50 in Figure 1. This provides a unitary window, which can then be assembled into a desired location, such as the wall of a motor home.

In some cases, it is found that bending the corners of the window, when the resilient insulating material 35 is in place, results in pinching of the resilient insulating material, and may even cut the insulating material. This may give rise to a pDrtion of the structure, at a corner, where heat can be conducted from the interior to the exterior of the structure. Accordingly, it is sometimes preferred to mate sections 10 and ll with projections 22 and 34, then bend the structure to provide the necessary corners for a window, without yet inserting the resilient insulating material 35. The glass is then inserted in the window, and the two ends of the extrusions are joined together to secure it. Once this is done, then notches are cut out from the corners of the completed window frame as shown in Figure 1 at 51, permitting in-sertion of the resilient member 35. The notches are then filled by suitable means, such as caulking material or sealant, to prevent access of moisture or leakage of heat therethrough.

"

Not only will the resultant assembly have the thermal block of the insulating members 22, 24 and 35 spacing the metal extrusions and providing insulation against the travel of heat in an inward or outward direction. They also as noted above combine to lock the assembly. The lock is such as to provide some resilience, particularly with respect to inward and outward movement of the panes. Furthermore there is a triple seal as-air to enter between the panes must traverse a tortuous path past U-shaped member 22, tubular member 35 and U-shaped member 24.
As illustrated in Figure 3, the building structure may include an outer body panel 36 and an inner body panel 37 separated by spaces 38. Insulation 39 can be inserted in the space between panels 36 and 37.
The dependent portion 28 of outer frame member 11 engages a layer of sealant 40 on the surface of panel 36.
Plate 18 is clamped to inner body panel 37 by screw 19 to secure the assembly in position. If there are slight deviations from linearity of panels 36 and 37, or even, in some cases, a moderate deliberate curvature, the connection provided by tube 35 is sufficiently flexible to accommodate this. The seals should be sufficiently flexible to escape damage from minor impacts during transportation or erection.
The fact that the triple seal includes seals of two different types, with the mounting surfaces facing in different directions and subject to different forces contributes to the probability that the stresses and strains developed during normal use will not result in the seal being broken.
