Corner connector for hollow double glazing frame section members

The invention relates to an angle connector for double window frame profiles according to the preamble of the main claim.

Specifically, the invention relates to an angle connector for double window frame profiles, each with a one Legs forming the base body, on which a plurality of this protruding strip-shaped fins are arranged.

From the prior art it is known, hollow frame profiles to use or hollow spacing profiles to multi-pane insulating glass produce or double windows. In this case, the Hollow section frame cut and by the angle connector a frame formed on which then the front side and back in each case a glass plate is bonded. The hollow section frame is filled with a hygroscopic agent, in order the humidity of the enclosed between the panes to remove air.

In such an angle connectors, it is necessary that these are easy to install and reliable in the frame hollow profile can be anchored. It makes both the nature the anchor and the issue of fatigue of the plastic material a crucial role.

The invention is based on the object of an angle connector to provide the aforementioned type, which with a simple Designed and easily and cost-effective producibility well anchored and ensures a high level of operational safety.

The DE 85 09 217 U1 shows such an angle connector.

According to the invention the object is achieved by the combination of features solved the main claim, the subclaims show further advantageous embodiments of the invention.

According to the invention it is thus provided that the distance between two adjacent lamellae is in a range of 1.5 to 2.0 mm lies.

By inventively provided spacing between the individual Slat is at the angle connector has a sufficiently high Number of segments feasible to secure retention and anchoring to ensure.

Furthermore offers the dimensioning according to the invention of the distances of the lamellae the possibility of the angle connector is inserted into the hollow frame profile, with this reliable to dig. Since the different embodiments A diversity of frame hollow profiles on its inside have configured raised or rough areas, for example, by indentations, weld beads or the like, the angle connector according to the invention is universally applicable for different frame hollow profiles used.

It is particularly advantageous when the distance between adjacent slats is 1.75 mm. It is to be understood that also each Kind of intermediate values ​​from the above-mentioned range between 1.5 and 2.0 mm can be favorable, for example, values ​​of 1.55, 1.65, 1.85 and 1.95 mm.

According to the invention it is further provided that the total height the basic body and the lamellae is larger than an associated Inner height of the hollow profile. Hereby, the lamellae forcibly deformed during insertion into the hollow frame profile, whereby the inventively provided wedge effect the lamellae results. The fins keep the angle connector thus not by frictional force, so as in the known angle connectors known from the prior art is, but by a specifically applied wedging action. This makes it possible, the individual lamella with the sure to wedge areas of the hollow frame profile, where are not additional characteristics or the like. According to the invention therefore there is a wedging or clawing of the lamellae, their effect especially occurs when a pull-out force is applied. Thus differ Lamellae according to the invention of the prior art known configurations in which the holder by Friction and pressing of the lamellas against the wall of the hollow profile frame takes place.

In order to promote a secure anchorage for the slat, it is especially advantageous if the free edge of the fin to form a cutting edge is chamfered. This increases the Surface pressure between the fin and the inner wall of Frame hollow profile.

According to the invention, it is furthermore particularly advantageous if the lamellae are arranged so that they are inwardly relative produced in a finished, out of the frame hollow profile Setting extend. The backs of the two base bodies then can a secure positioning of the two ends of the ensuring frame hollow profiles, whereby any type of game can be excluded.

It is particularly advantageous if the insertion length 24 mm is. This means that the basic body substantially is 24 mm long, so that a sufficiently long distance with the Slats can be filled, so that a correspondingly high Number of segments present. The insertion length can also 20 to 30 mm, depending on the dimensioning of the frame hollow profile.

The base body is preferably at its the lamellae opposite side with a sawtooth ribbing provided. These also contributes to support for and brings about good engagement the frame hollow profile.

The angle connector according to the invention can in two different be constructed embodiments. On the one hand it is possible, the two base bodies by means of an integrally pivotally connected thereto hinge region together. Thereby, it is possible to use other, not to create rectangular shapes of glazing units.

In an alternative embodiment, it is provided that the two basic body by means of an integrally connected to this Corner portion are firmly joined together. hereby yields the desired 90 ° angle.

The two embodiments described above can be realized very easily in that an injection mold slightly is modified. This results in very favorable Manufacturing costs.

For architectural reasons, it is often necessary, incorporate lattice windows. However, these have in each case common large glass sheets on, so that the individual rungs be inserted just for decoration. By means of the invention Angle connector, this is a particularly simple manner characterized possible that four angle connector by means of at least one, preferably two cross plates together are connected, the coupled with the solid corner regions are. Thus, the cross panels can on in the simplest way the respective angle connectors are snapped. For the Manufacture of cross plate itself thus reaches a relatively simple tool, so that overall reduce the costs.

In the invention it is provided that the Cross plate substantially centrally with an elastically over the surface of the cross plate protruding piece on these trained damping region is provided. This formed raised in the original production and is somewhat deformed when placing the glass panes. Thus it can dampen and compensate for vibrations of the glass plate.
