Abstract
To fill insulating glass panes with a heavy gas, one of the glass plates (40) of which the insulating glass pane is formed is initially only partly joined to the other glass plate (42) during assembly and to that end is flexed along one edge so that a gap is temporarily left between the glass plate (40) and the spacer (41) and a heavy gas can be introduced through that gap to fill the interior space of the insulating gas pane.
Claims33
A process of assembling insulating glass panes, wherein an interior space is provided between pairs of glass plates, which are spaced apart and adhesively joined along their edges by a framelike spacer and which during their assembling are in contact on their outside planar surfaces with positioning surfaces, and wherein said interior space is filled with a gas other than air, in that
- at least one of the glass plates is elastically flexed along an edge of the glass plate,
- the spacer is attached to one of the glass plates (hereinafter called the "first" glass plate) before or during or after the flexing of one of the glass plates,
- the spacer is attached to the other glass plate (hereinafter called the "second" glass plate) while the flexing is maintained to create and to keep open an access opening to the interior space between the glass plates,
- the gas is admitted to the interior space through the access opening thus provided, and
- the access opening is closed in that the resilient flexing is eliminated,
- characterized in that at least one glass plate together with its respective positioning surface contacting it is flexed so that the outside surface of the glass plate is concave.
A process of assembling insulating glass panes, wherein an interior space is provided between pairs of glass plates which are spaced apart and adhesively joined along their edges by a framelike spacer and which during their assembling are in contact on their outside surfaces with positioning surfaces, and wherein said interior space is filled with a gas other than air,
- the spacer is attached to one of the glass plates (described hereinafter as the "first" glass plate) and subsequently to the other glass plate (described hereinafter as the "second" glass plate),
- at least one of the glass plates is resiliently flexed along an edge of the glass plate to provide an access opening to the interior space between the glass plates,
- a gas is introduced into the interior space through the access opening thus provided, and
- the resilient flexing is eliminated to close the access opening,
- characterized in that at least one glass plate together with its respective positioning surface contacting it is flexed so that the outside surface of the glass plate is concave.
An apparatus for assembling insulating glass wherein an interior space is provided between pairs of glass plates (40, 42), which are spaced apart and adhesively joined along their edges by a framelike spacer (41) and wherein said interior space is filled with a gas other than air, comprising
- backing means (6) for supporting and positioning the glass plates (40, 42),
- retaining means (15), which are parallel to the backing means (6) and arranged at a variable distance therefrom and serve to retain and position one of the glass plates (40) at a distance from the other glass plate (42), wherein either the backing means (6) or the retaining means (15) or both define a positioning surface (29), which is intended to contact the outside surface of one glass plate (40) and in which the forward surface of an elongate suction device (20) is disposed, which is directed toward the glass plate (40), and
- means (31) for supplying the gas,
- characterized in that the suction device (20) is arranged on the positioning surface (29) in a resiliently deflectable portion thereof, which is attached to the retaining means (15) and/or to the backing means (6), and said portion is engaged by a pulling and/or pushing means (52 to 56) for flexing the portion.
