Description

(54) A GLASS PANEL READY FOR MOUNTING (71) 1, JRGEN SKOUBO JOHANSEN, a Danish Subject of Hjortespringparken 26, DK-2730 Herlev, Denmark, do hereby declare the invention, for which I pray that a Patent may be granted to me, and the method by which it is to be performed to be particularly described in and by the following statement: The invention relates to a glass panel ready for mounting, comprising at least two parallel glass layers with a space in between, said glass layers optionally forming an independent hermetically sealed insulating window unit, and a plurality of mounting strips extending completely or partly along the periphery of the glass layers or optionally along the periphery of the insulating window.

Many of the known glass panels are defective, since the glass layers and the mounting strip are connected at the edge surfaces of the glass layers, ie: the surfaces perpendicular to the planar surfaces of the glass layers. This implies that the structure and accuracy of the connection is rather weak, since said surfaces are often too small and rather inaccurate, cf.

the amorphous structure of the glass and the consequently necessary tolerance required to allow for cutting. Further, it is difficult to determine the correct amount of sealing compound for the connection, when the production of the panel is to be carried out quickly, when it is desired to avoid discharge of material outside the strips.

The object of the invention is to provide a glass panel permitting an accurate dosage rate of sealing compound for the connection between strip and glass during a quick production of the panels.

According to the present invention there is provided a double glazed unit comprising an inner glass sheet spaced from an outer glass sheet, and a hollow mounting strip adhesively conjoining a single edge zone as herein defined of the inner sheet to a single edge zone of the outer sheet; the periphery of the outer sheet extending beyond that of the inner sheet.

"Edge zone" here means "a narrow strip on the planar surface of each glass layer adjacent the periphery of said glass layer".

Since the edge zones of the glass layers are almost planar, and the spacing between the edge zones and each strip is well-defined, it is simple to predetermine the correct amount of adhesive sealing compound for each sealing, whereby uncontrolled flowing of the compound beyond the glass is avoided. Consequently, it is not necessary to brush off superfluous sealing compound.

The panel is particularly well suited for a quick and mechanical mass production.

The sealing compound is of such a type and present in such amount that the glass layers may be supported by the strips in a reliable manner. Since the mounting strip is hollow the panel weight is simultaneously reduced.

According to one aspect of the invention the mounting strip may be either L-or Zshaped, when Z-shaped the two strip members corresponding to the free flanges of the Z, thus permitting a very simple construction.

In another aspect of the invention a portion of the mounting strip may extend somewhat beyond the peripheral edge of the outer glass sheet along the plane of the glass layers. This ensures that the outer glass edge is relatively protected when many panels are piled up just after the production to allow drying of the sealing compound.

Since the mounting strip is hollow it easily fills the spacing between the displaced glass edges without increasing the weight of the panel.

The invention will be described below with reference to the accompanying drawing, in which Fig. 1 is a fragmentary sectional view of a first embodiment of the glass panel according to the invention, wherein the mounting strip is hollow and comprises two portions forming an L-shape, and wherein the two sealing portions are provided at two edge zones facing the right.

Fig. 2 a fragmentary sectional view of a second embodiment of the glass panel according to the invention -- said embodiment being similar to that of Fig. 1 wherein the strip is arranged between an edge zone facing the right on the projecting glass layer and an edge zone facing the left on the shorter glass layers, Fig. 3 a fragmentary sectional view of a third embodiment of the panel, wherein the strip portions form an L, only one of said portions being hollow, and wherein the sealing portions are provided at two edge zones facing the right on the glass layers, Fig. 4 a fragmentary sectional view of a fourth embodiment of the panel, wherein the strip is substantially Z-shaped, and the sealing portion is provided at two edge zones facing the right on the glass layers, Fig. 5 a fragmentary sectional view of a flfth embodiment of the panel - said part being similar to Fig. 4 - wherein the strip is arranged between a sealing portion facing the right on the projecting glass layer and a sealing portion facing the left on the short glass layer, Fig. 6 an embodiment of the panel said embodiment being similar to the embodiment of Fig. 3 - wherein the strip is arranged between two edge zones opposing each other.

Fig. 1 illustrates a glass panel comprising two parallel glass layers 1 and 2 with a space 3 in between, said layers being connected by means of a spacer 4. A mounting strip 8 is situated along the periphery of the glass layers.

The glass layers 1 and 2 comprise edge surfaces 11 and 12, respectively, which are displaced relative to each other, cf. Fig. 1.

The mounting strip 8 comprises a first strip member 8a and a second strip member 8b, said members being clearly separated by a third intermediate strip member 8c. The glass layer 1 comprises an edge zone la juxtaposed an edge zone lb, and similarly the glass layer 2 comprises an edge zone 2a juxtaposed an edge zone 2b. The strip member 8b opposes the edge zone 2b, whereby a second sealing zone 20 is formed.

Since the sealing zones oppose the planar edge zones, it is easy to determine the correct amount of sealing compound for the glass, whereby uncontrolled flow of the sealing compound outside the strip is avoided. Besides, the strip comprises two hollow portions 8' and 8" forming an shape. The strip member 8a is provided on the portion 8', and the strip member 8b is provided on the portion 8".

Fig. 2 illustrates an embodiment wherein a glass panel similar to the embodiment of Fig. 1 has a mounting strip 9 arranged between the edge zone 1b of the layer 1 and the edge zone 2a of the layer 2. The first strip member is indicated by 9a and the second strip member by 9b.

Alternatively a mounting strip 15 may, cf. Fig. 3, comprise a hollow portion 15' and a solid portion 15". The first and the second strip members are indicated by 15a and 15b, respectively.

Fig. 4 illustrates a glass panel with a mounting strip 16 which is substantially Zshaped. The first strip member 16a and the second strip member 16b form free flanges at the remote ends of the Z-section. The corresponding sealing portions are provided in two edge zones ib and 2b.

In the embodiment of Fig. 5 a mounting strip 17 and its first and second strip members 17a and 17b respectively cooperate with the edge zones 1b and 2a of the layers 1 and 2.

Fig. 6 illustrates an embodiment wherein the strip substantially corresponding to the embodiment of Fig. 3, but the strip 19 comprising the strip members 19a and 19b, is arranged between the edge surfaces lb and 2a of the glass layers.

To ensure that each sealing portion possesses the necessary load capacity, the sealing may be made of a curable adhesive of the two-component type or of a soldering material.

In Fig. 1 the glass layers 1 and 2 may form an insulating window unit, and it will be appreciated that the spacer rib 4 may be deleted. Instead of two glass layers, three glass layers may be provided, i.e. a projecting glass layer corresponding to the glass layer 1 and two short, equal glass layers corresponding to the glass layer 2, all three layers having spaces in between.

Such an extra glass layer is indicated by a dotted line at 21 in Fig. 1.

Finally, it should be noted that the mounting strip 8 may, cf. Fig. 1, extend somewhat beyond the edge surface 11 of the glass layer 1, whereby the edge surface 11 is better protected than when the strip is otherwise positioned.

WHAT I CLAIM IS: 1. A double glazed unit comprising an inner glass sheet spaced from an outer glass sheet, and a hollow mounting strip adhesively conjoining a single edge zone as herein defined of the inner sheet to a single edge zone of the outer sheet; the periphery of the outer sheet extending beyond that of the inner sheet.
