Corner drive for connecting rod fittings of windows, doors or the like.

The innovation concerns a corner drive for espagnolette fittings of windows, doors or the like. With an angular housing that has a guide channel for the tensile and compressive rigid movement of a flexible Deflection member, for example made of spring steel strips, contains which is straight in the two housings schenkein and in the corner area has an arcuate guide from section, with both housing legs in the corner area around one to the main plane the angle housing normal axis are articulated, which is held in bearing eyes on both legs.

By DE-GM 81 28 583 a corner deflection has been proposed in which both legs in the corner area an axis normal to the main plane of the angular housing are articulated to one another, the arcuate one Guide section of the guide channel with its longitudinal center line runs through this axis. Each leg has a surface consisting of two partial surfaces facing each other at obtuse angles, with its apex on the axis, the end face on the one hand a receding one running concentrically around the axis Storage area and, on the other hand, one that is also concentric around the Includes axis guided, protruding bearing surface. The recessed bearing surfaces of each leg engage with the projecting ones Bearing surfaces of the other leg alternate, knee-jointly into one another and on both outer surfaces of the legs Sector-shaped pegs and the pegs of both sit in each case Legs each engage in a common bearing ring.

This configuration of a corner deflection is advantageous insofar as it can be used in one and the same embodiment for all in the The corner bracket designs of windows and doors that occur in practice can be used and, to a certain extent, differ in their handling automatically adapts to the respective installation conditions. The same The solution principle can be used on window and door constructions in all practically used types of material, provided that Angular housing on the installation conditions resulting from the respective material selection on the windows and doors will be voted on.

However, it was also suggested by DE-GM 82 01 403 already a corner deflection for connecting rod fittings of windows, doors or the like. In which one on the back side

Flexible deflecting members, e.g. steel strips, is arranged, the two in one piece by an arcuate transition area having connected legs. Here, the guide channel is designed to be deformable in its curved transition area.

['forms. Furthermore, the legs of the holding rail carrying it are available

j angularly displaceable to one another around their corner area

j in connection, with at least one of the legs of the guide

channel is limited longitudinally displaceable on the adjacent leg of the retaining rail. In this case the two legs are The corner area of the retaining rail is articulated to one another around an axis normal to the main plane, namely, that bearing pins on one leg of the retaining rail engage in bearing eyes on the other leg of the same "

This embodiment of a corner deflection is also suitable for all corner bracket designs of windows that occur in practice and doors and is easy to use Way to adapt to the respective installation conditions.

The innovation should now be a corner deflection of the one specified at the beginning Generic are created, which compared to the above-described, known embodiments structurally and in terms of assembly is further simplified.

To achieve this goal, according to the innovation, the outer limitation of the arcuate guide section of the guide channel through the inner surfaces of the bearing eyes for the axis connecting the two housing legs formed, while the inner boundary of the same consists of tongues formed on each of the housing legs, which are located in all effective angles, at least the positions of the two legs partially overlap each other "

According to the innovation, it is also proposed that the arc radius on the inner surfaces of the bearing eyes is the largest occurring corresponds to the outer radius of curvature for the spring steel strips, while the radius of curvature of those facing the bearing eyes Areas of the tongues is adapted to the smallest occurring radius of curvature of the spring steel strips.

In a preferred embodiment of a corner deflection, the tongues on the legs are each provided below the bearing eyes. According to another development, however, it is also possible to use the tongues on each leg from several To let the width of the spring steel strips exist with spaced-apart lamellae that interlock alternately.

Further features and advantages of a corner drive according to the innovation are shown below with reference to one in the drawing illustrated embodiment explained in more detail. Here shows

a corner drive according to the innovation in its setting for installation in a ν obtuse-angled wing corner,

FIG. 2 shows a view of the corner drive according to FIG. 1

in the direction of the arrow II
and

Fig. 3 on a larger scale the in Fig. 1 with III

marked area.

In Fig. 1 of the drawing is - purely schematically - the corner area 1 of a window or door sash is shown, which of two Legs l 'and l "is formed, which in the embodiment shown extend at an obtuse angle to one another. The two Legs 1 'and 1 * of the corner area 1 can, however, also extend at right angles to one another. In any case, you can One and the same corner drive 2 can be installed in the corner area 1 of the window or door sash. So that the corner drive 2 the different angular positions between the two legs l ' and 1 "of the corner area 1 can be easily adjusted, are the two Housing legs 3 'and 3 "of the angular housing 3 in their relative Angular position to one another designed to be adjustable.

In the illustrated embodiment of a corner drive 2, the two housing legs 3 'and 3 "of the angular housing 3 are as

Die-cast parts made of metal, in particular zinc or Brass die-cast. In some cases, however, they can also be used as injection molded parts made of wear-resistant Made of plastic.

At the ends facing each other, the two housing legs are 3 'and 3 "of the angular housing 3 are each provided with an integrally formed bearing eye 4', 4" into which an axle bolt 5 engages, which extends normal to the main plane of the angular housing 3.

Inside the housing legs 3 'and 3 "of the angular housing 3 a guide channel 6 is formed in the usual way for a flexible deflecting member 7, the two rectilinear guide sections 6 'and 6 "and an arcuate central portion 6'".

The straight guide section 6 'and half of the adjoining arcuate guide from section <o " are in the housing leg 3' of the angular housing 3, while the other straight guide section 6" and the associated half of the arcuate guide section 6 "" in Leg 3 "is formed.

The outer boundary of the arcuate guide from section 6 '"of the guide channel 6 is half of the inner surfaces 8' and 8" of the bearing eyes 4 'and 4 "on the housing

Legs 3 'and 3 * formed. To the inner limitation of the Arcuate guide section 6 '"of the guide channel 6, however, are special to the housing legs 3' and 3" Tongues 9 'and 9 "are integrally formed, which are at least partially in all effective angular positions of the two housing legs 3' and 3" cover and face the bearing eyes 4 'and 4 ", Have arcuate guide surfaces 10 'and 10 ".

The radius of curvature on the inner surfaces 8 'and 8 "of the bearing eyes 4' and 4" corresponds to the largest occurring outer radius of curvature for the flexible deflecting member 7 consisting of several spring steel strips Bearing eyes 4 'and 4 "facing surfaces 10' and 10" of the tongues 9 'and 9 "at the smallest occurring bending radius of the flexible Deflection member 7 adapted.

While the two bearing eyes 4 'and 4 ", as can be seen from FIG is, together have a width that is significantly greater than the width of the slidably received in the guide channel 6, flexible deflection member 7, it is sufficient for the tongues 9 'and 9 "if their common width is approximately equal to the width of the Deflection member 7 is.

On the other hand, there is a further development possibility that the 2; lungs 9 'and 9 "on the two housing legs 3' and 3" of the Angle housing 3 each of several over the width of the flexible deflecting member 7 spaced next to each other

There are lamellae that interlock with one another. So it is possible, for example, on each of the two housing legs 9 'and 9 "two such slats at a distance next to each other and to be provided in such a way that these are in the articulated connection of the two housing legs 3 'and 3 "via their bearing eyes 4 'and 4 "and the bearing axis 5 are held in engagement with one another.
