Abstract

Improvement at windows with one or more layers of glazing with externally glued crosspieces (2). To simplify fitting in the frame, an external crosspiece frame/outer window moulding (1), preferably with the same height as the crosspieces (2), is attached at the glazing (5) at the edge thereof.

Description

GLAZED WINDOW UNIT WITH GLUED CROSSP I ECES

The invention concerns a glazed window unit as indicated in the introduction to Claim of Patent 1.

Previously, windows consisted of small, in¬dividual panes since glass manufacturers were unable to produce large panes of glass. Today small paned windows are in demand, but at the same time, people want large sealed glazing units of insulated glass. Solutions have included artificial crosspieces fitted outside the window or between the plates of glass in a sealed glazing unit.

In GB patent application no. 2164694 an external crosspiece frame system is described which is fixed directly onto the glazing bead. The glazing bead usually has a sealing strip inside a groove.

In DE printed publication no. 2732687 an external crosspiece system is described which also is attached to the external glazing bead. This patent includes an internal glazing bar system which is built directly into the body of the window.

In US patent no. 3.474.587 an externally hinged crosspiece frame is described where a complete pane of glass is laid inside a sealing strip. This is a special design for display windows with crosspieces. In NO "auslegeschrift" no. 141959 a crosspiece frame is described which is fitted directly onto the glazing bead. Two types of crosspiece frame are conceived of for single glass windows in interior doors. Apart from the above, sealed glazing units have come onto the market with two component crosspieces in a variety of patterns and designs which can be glued directly onto the glass. In triple glazing systems, the two component crosspieces are fitted to each side of the interior glass as in NO patent specification

129451, or on each side of the outer glass. With double glazing units it has become usual to fit two component crosspieces on the respective s i de s of the out s ide gl as s . I t has al so become more usual to fit two component crosspieces directly on each side of single glazing units.

There has been one considerable problem with panes where crosspieces are fitted directly onto the glass: namely, how to mount the individual panes into their respective frames. The most difficult problem has been with windows where the crosspieces have been 5 mm or more in height.

The basic cause of the difficulty is that the various window and door manufacturers have not standardized the depth of the glazing rebate or the dimensions and angles used for the glazing beads. Furthermore, they also use different sealing beads for mounting the glass and these lie against the glass at a variety of angles. A remedy to this has been to bevel the protruding crosspiece ends to match the angles of the glazing and sealing beads. This is a time-consurning operation which does not simplify the mounting of the individual panes into their respective frames.

The present invention has sought to find a In accordance with the present invention the solution will be realized by designing a window as specifed by Claim of Patent 1. Other aspects of the invention are stated in Claims 2 and 3. The term "windows" also includes glass doors/doors with panes of glass.

The invention will be described in more detail with reference to the illustrations, where:

Fig. 1 shows a front perspective of a section of a window which is designed in accordance with the invention, which has glued crosspieces,

Fig. 2 is a lateral cross-section through the same window,

Fig. 3 shows a cross-section of two different crosspiece frame mouldings,

Fig. 4 shows a cross-section of a crosspiece frame moulding with a guide edge facing downwards, whlist

Fig. 5 shows a cross-section of a crosspiece frame moulding with a countersunk groove for a sealing strip.

In Figs. 1 and 2 there is a section of a window with a frame 4 and double glazing 5, 5' mounted inside the frame. On the side that faces away from the rebate of the frame, the glass is edged by a glued crosspiece frame 1. The crosspiece frame 1 has a moulding to an external glazing bead 3. Other means of attachment are silicone padding, double faced adhesive tape or other appropriate means.

An alternative is that the crosspiece frame is loose and held in position by the glazing bead 3, which could be an aluminium moulding for example. A further alternative is attaching the crosspiece frame to or being an integrated part of the window's central crosspieces 2. Internally in the window between the double glazing 5, 5' there is an equivalent set with a crosspiece frame 6 and crosspieces 2'. The crosspiece frame 6 can be manufactured as half of a crosspiece and held in position by an aluminium sealing bead around the edge.

Fig. 3 shows cross-sections of two mouldings that can be used for the cross-piece frame 1 and the crosspieces 2 (left) respectively, and for the crosspiece frame 6 between the double glazing 5, 5'.

Fig. 4 shows a cross-section of a moulding with a guide edge facing downwards, this is to make external attachment of the glass easier. The guide edge will also help protect the glass during transport and fitting.

Fig. 5 shows a cross-section of a moulding which can be used in the crosspiece frame 2, with a countersunk groove for a sealing strip.

The moulding material can be manufactured from thin edged aluminium, plastic or wood or other appropriate materials.

Glass with external crosspieces can have such crosspieces fitted externally on one or both sides. For interior doors it will be best to have crosspieces on both sides of the glass. This could also be the solution to use with sealed glazing units with double or triple glazing. In such cases aluminium spacing bead could be fitted between the layers of glass. This solution in accordance with the invention will be particularly advantageous, since other means of adjustment to match the frame would be complicated and time-consuming.

Glass with externally-attached crosspieces 2 with a crosspiece frame 1 which acts as an external moulding on the outside of the glass, can be used with all types of windows and glass doors/doors with windows in wood, plastic, aluminium and aluminium/wood.

Claims

CLAIM OF PATENT
