Abstract
The insulating glazing unit in accordance with the invention consists in its simplest form of two panes 1 and 2 which are joined together by means of a shaped body 13 constituted by a textile spacer fabric. By means of its high elasticity, flexurally rigid rib fibers 16 the textile spacer fabric renders possible a force transmitting coupling of the panes and the formation of a dimensionally stable and self-supporting sheet body. This sheet body is suitable in particular for the production of frameless window lights.
Claims41
An insulating glazing unit comprising at least two panes arranged in parallelism to each other and connected together by a marginally surrounding spacer, characterized in that the spacer is constituted by a shaped body which possesses a plurality of elastic, flexurally rigid and mutually intersecting filaments, which extend transverse in relation to the plane of the panes and form a force transmitting buttressing means between the panes.
A method for the production of a frameless insulating glazing unit, characterized in that in a surrounding manner on the edge of a pane a resin impregnated spacer fabric comprising at least two oppositely arranged covering layers and, perpendicularly to the extent of the area of the covering layers, rib fibers is laid, the second pane is laid on with an accurate fit and the resulting laminate is compressed with an accurate fit in a pressing mold so that the panes are bondingly connected with the covering layers of the fabric with a surrounding arrangement and at the edge, whereafter the pressing mold is opened, the rib fibers erect themselves and the resin is cured.
A method for the production of a frameless insulating glazing unit, characterized in that a textile spacer fabric comprises at least two mutually opposite covering layers and rib fibers extending transversely in relation to the extent of the area of the covering layers and is impregnated with resin and such resin cured and in that from such spacer fabric after curing shaped bodies are produced in a form ready for assembly, which are then connected together at the edge and in a surrounding manner and in a manner defining a distance apart are arranged between the at least two panes and are connected in a bonding manner with the panes.
