Description

The invention relates to a connector for window profiles and also to a cross connector for double-window frame profiles with a central central region from which extend cross-shaped legs, which are inserted in hollow profiles.

The prior art shows a variety of double-window constructions with fittings and center crosses. For example, the center crosses may have a hollow profile with a relatively large cross-section to form a so-called. Viennese rung. However, it is also possible to use two mutually parallel hollow profiles and spacers genann6 with a smaller cross-section. Accordingly, the connector or the cross connector is to be designed.

In the formation of a fitting is required that the fitting is as easy as possible in a variety of profiles I can be used and still slipping out of different profiles is largely avoided. A known from the prior art fitting is for example from the EP 1 522 668 A2 known.

In central crosses of insulating glass double windows also results in the need to provide a rattle guard to avoid a rattling or movement of the glass sheets rattling of the hollow profile construction. For this purpose, a wide variety of constructions with applied or inserted damping elements have been proposed. These are very expensive to produce and therefore costly. Furthermore, they require a higher production cost, since additional steps to install the Rattle protection are required. A known from the prior art center cross is for example from the DE 20 2005 003 193 U1 known.

The invention has for its object to provide a connector for double-window profiles, which is as safe to use in the profiles as possible that slipping out of the connector from the profile is largely excluded, and is also suitable for a cross connector, the can be used for different profiles with a simple design and simple, cost manufacturability and has a good rattle protection.

Suitably, in addition, in each case at least one of the upper and lower triangular stiffeners, a hole can be formed, in which optionally suitable insulating elements can be used.

A cross connector according to the invention also comprises, in particular, a slender U-shaped spring element, which is suitably inversion-symmetrical with respect to a center of the frame and in which one end of the U-shaped spring elements is connected to the frame and the other end of the spring elements is formed plate-like thickened and each dominates the top or bottom of the frame. In the inserted state of the cross connector between insulating glass panes are the free plate-like thickened formed ends of the U-shaped spring elements respectively on the inside of the adjacent insulating glass panes under spring pressure of a coil spring, so that the cross connector is held clamped with the window bars firmly between the insulating glass panes. In this way it is also avoided that the window bars strike against the insulating glass panes, whereby an inventive rattle guard is provided with particularly effective spring action.

It is clear that in a cross connector according to the invention can be dispensed with the above-described formation of the inner cross-connections and the front end connection of the inner support in particular with the through hole, wherein the two inner support of a Cross connector according to the invention can also be interconnected by suitable differently shaped reinforcing and stiffening elements.
