Description

The invention relates to a Eckumlenkung for a window, a door or the like, with two push rods and connecting the push rods, flexible corner connector, wherein the Eckumlenkung has a two housing leg having Winkelgehäuse in which the two push rods and the Eckverbindungsglied are longitudinally displaceable, and wherein the angle housing is a plastic housing and consists of a one-piece, angular base housing having an outer angle wall and two side angle walls.

From the DE 4417842 A1 is a Eckumlenkung known, which has an angularly curved face-plate, are mounted on the two push rods and the push rods connecting, flexible corner connecting member. Since the push rods rest in each case with only one side against the faceplate and the corner connecting link is guided in the free arc, the known Eckumlenkung is only suitable for small windows in which the Eckumlenkung does not have to transmit large operating forces.

Furthermore, the prior art shows the document FR 2 303 146 A1 , This describes a corner drive for espagnolettes on windows, doors or the like made of metal, plastic or similar materials frame profiles, which have undercut profile grooves in which the drive rods are displaceably guided and the angle guide for the deflection formed by flexible bands or strips at the frame corner is secured by laterally projecting strips or noses and / or by associated clamping parts with its two legs. It is provided that the two legs of the angle guide have a different cross-sectional height and while the guide channel for the deflection in the flat cross-sectional profile of the one leg is closer to the inside leg than in the high cross-sectional profile of the other leg.

The invention has for its object to provide a corner deflection for a window, a door or the like, which is highly resilient and for all applications (formats, Weights, safety classes) in windows, doors and the like can be used. Furthermore, a simple structure should be present, which ensures a high level of manufacturing safety.

This object is achieved in a Eckumlenkung of the aforementioned type in that the plastic housing has two housing cover, which form an inner angle wall of the angle housing, each housing leg having a housing cover, and the base housing and the housing cover welded together, in particular ultrasonically welded, are.

Basically, the Eckumlenkung invention is characterized by the fact that it has a two housing leg having Winkelgehäuse in which the two push rods and the Eckverbindungsglied are longitudinally displaceable, and that the angle housing is a plastic housing and consists of a one-piece, angular base housing and two housing covers, wherein the base housing having an outer angle wall and two side angle walls, the housing cover forming an inner angle wall of the angle housing, each housing leg having a housing cover, and the base housing and the housing cover welded together, in particular ultrasonically welded, are. Since the push rods and the flexible corner connecting member are mounted in the angle housing, very large forces can be transmitted, that is, there is a heavy-duty corner drive before. Due to the design of the angular housing made of plastic results in spite of the high load capacity a smooth movement in a displacement of the push rods and the corner connecting member, wherein the push rods and the corner connecting member preferably made of metal. The plastic used for the angle housing is preferably chosen such that it has high dimensional stability, high abrasion resistance and high toughness high lubricity for the push rods and the corner connecting member. A variety of different plastics for this purpose are available to the person skilled in the art. Preferably, POM (polyoxymethylene) can be used as a plastic material, since this plastic has excellent resistance, is hard and tough, has very good sliding properties and is hydrophobic. Due to the inclusion of the two push rods and the corner connecting member inside the angle housing, these components are securely guided at a high load, so that a lateral deflection can not occur. Accordingly, the angular housing preferably has a correspondingly adapted bearing channel for supporting the components mentioned, which nevertheless guides the components smoothly with little play. Due to the construction of the plastic housing, namely the one-piece, angular base housing and the two housing covers is not yet mounted housing covers by simply inserting the angle inside the assembly of the Eckumlenkung possible, wherein after inserting the two housing cover placed on the base housing and all housing parts welded together, in particular ultrasonically welded, are. Due to its outer angle wall and its two side angle walls lying laterally to the outer angle wall, the basic housing has a U-shaped cross-section which is open towards the interior of the angle. Even this construction has a high strength. By means of the two housing cover the angle inside of the basic housing is closed, whereby the stability is increased again. By welding the base housing and the housing covers, a coherence of the entire angle housing is achieved, so that it is highly stable and can safely absorb high loading forces.

According to a development of the invention, it is provided that the housing cover touch an inner corner angle and there welded together, in particular ultrasonically welded, are. The housing cover are thus welded to the base housing, but also welded together, namely where they touch each other. This is the case on the inside corner.

A development of the invention provides that the housing cover are formed on the inner angle corner such that one of the housing cover is acted on the outside of the other of the housing cover with its end face. The other housing cover thus prevents, in particular in the region of the inner angle corner, lifting of the one housing cover from the basic housing.

It is envisaged that the base housing has two basic housing legs. The base housing is U-shaped in cross-section and has an overall angular shape, which has two angular portions, which are formed by the basic housing legs.

It is preferred if the angle housing, in particular the base housing, on one of the housing legs at least one lateral Einschraiebleistenvorsprung for insertion into a mounting groove of the window, the door or the like, wherein the Einschiebleistenvorsprung extending in the direction of the longitudinal extension of the housing leg. Preferably on both sides of the housing side side Einschiebleistenvorsprünge provided. The mounting groove of the window, the door or the like has a corresponding cross-sectional shape, so that insertion of the angle housing is made possible. The other, no side Einschiebleistenvorsprünge having housing legs can therefore be easily inserted into its region of the mounting groove when inserting the Einschiebleistenvorsprünge, this insertion is not in Montagagenutlängsrichtung, but transverse to Montagagenutlängsrichtung the associated mounting groove.

It is preferably provided that the angle housing, in particular the associated housing cover, on the other of the housing leg has at least one insertion projection for insertion into an opening in the bottom of the mounting groove, wherein the insertion projection extends transversely, in particular at right angles, to the longitudinal extent of this housing leg. If - as described in the previous paragraph - the angle housing inserted with its Einschiebleistenvorsprüngen in the associated mounting groove, it also takes the insertion of the at least one insertion into the opening of this housing leg associated mounting groove. These respectively associated mounting grooves are, for example, a vertically extending mounting groove and a horizontally extending mounting groove (in particular on the associated, mutually angled frame profiles of a sash frame of a window, a door or the like). Due to the holding of both housing legs, namely on the one hand by the at least one Einschraiebleistenvorsprung and on the other hand by the at least one insertion, a stable, heavy-duty determination of the Eckumlenkung to the window, on the door or the like is guaranteed. The installation of the Eckumlenkung on the window, on the door or the like is preferably carried out such that at the housing leg of the angle housing, which has the Einsteckvorsprung, when locking the window, the door or the like, the associated push rod is inserted into the angle housing. This results in a significant relief of the mounting groove, (profile) in this locking process. By means of the at least one insertion projection, the maximum load force, which acts in the closing direction when locking on the groove geometry of the mounting groove of the sash of the window, the door or the like to the outside, is significantly reduced. When unlocking, on the other hand, firstly, a significantly lower force acts and, secondly, in a different direction, inwards. The insertion projection is in particular a so-called drill journal, that is to say a journal which is inserted into a bore / recess during assembly.

According to a development of the invention, it is provided that the base housing and the housing cover are designed to be safe in mounting, such that the housing cover fits in each case in only one orientation and at only one position on the base housing are. Preferably, it is provided that the assembly exchange security is formed by projections and depressions into which the projections engage, on the housing covers and on the main housing legs. Therefore, a housing cover can be fixed only on one of the basic housing legs and only in a single orientation there, since the projections and depressions are so on these components, so that always a projection can engage in a depression. In the other housing cover, which is to be fastened to the other main housing leg, appropriate conditions are provided, but these conditions differ from those of the other housing cover and the associated basic housing leg, so that the housing cover interchangeable with each other also can not be mounted, but only a single unique Take position. This ensures a high degree of production safety, since no incorrect assembly can take place.

The invention further relates to a window, a door or the like, with at least one corner drive, as described above.

Preferably, the window, the door or the like on a square or rectangular frame and a square or rectangular sash, with at least two, preferably three, corners of the sash equivalent corner joints are arranged. Each of these corners is therefore provided with the same, that is, identically constructed, corner drive, whereby a variety of components is prevented and virtually a standard Eckumlenkung exists.

The invention further relates to a window system or door system having a plurality of different sized windows or a plurality of different sized doors, wherein on the windows or on the doors of each identically formed Eckumlenkungen are arranged, each window or door having at least one corner. The said respective system accordingly relates to windows of different sizes or doors of different sizes, but regardless of size, the same, ie identical, corner deflections are always used. Therefore, a uniform corner drive is used for all applications.

The FIG. 1 shows a corner guide 1 for a window, a door or the like. The Eckumlenkung 1 has two push rods 2, 3, which in a corner region 4 of the corner 1 via a from the FIG. 1 not obvious, but in the FIG. 4 illustrated, flexible corner connecting member 5 are interconnected. The corner drive 1 has an angle housing 6 which has two housing legs 7, 8. In the angled housing 6, the two push rods 2, 3 and the corner connecting member 5 are mounted longitudinally displaceable. The angle housing 6 is formed as a plastic housing 9. The angle housing 6 consists of a one-piece, angular base housing 10 and two housing covers 11 and 12th

The base housing 10 has an outer angle wall 13 and two side angle walls 14 and 15. In cross-section results with respect to the outer angle wall 13 and the two side angle walls 14 and 15, a U-shaped contour. This contour is closed by the two housing cover 11 and 12. The housing cover 11 and 12 together form an inner angle wall 16 of the angle housing 6, wherein each housing leg 7, 8 one of the housing cover 11, 12 has. The base housing 10 and the housing cover 11, 12 are welded together, in particular ultrasonically welded. Therefore, a plastic welding process is used.

In the manufacture of the corner joint 1, the procedure is such that inserted into the base housing 10, the two push rods 2 and 3 together with the corner connector 5, then the housing cover 11 and 12 are supplied and welded to the base housing 10. The welding results in welds 17. The welding is preferably carried out over the entire length of the housing cover 11 and 12 and on both sides of these.

Preferably, it is provided that in the region of an inner angle corner 18, the housing cover 11, 12 abut each other, so touch, in particular provided that they there, so in their contact area, also welded together, in particular ultrasonically welded, are. Again, the plastic welding process is used. This results in a further weld 17. The welding is preferably carried out over the entire width of the housing cover 11 and 12th

By the mentioned housing construction of the angle housing 6, the push rods 2 and 3 and also the corner connecting member 5 are optimally supported and guided, so that very large forces can be transmitted. End side, the push rods 2 and 3 connecting members 19. Preferably, the connecting members 19 are attached to the push rods 2 and 3. The connecting members 19 can be connected to other fitting elements, for example with drive rods. From the FIG. 4 It can be seen that the base housing 10 and that the two housing covers 11, 12 each have on the inside guide contours 20, the precise and substantially backlash the two push rods 2 and 3 and the corner joint 5 store such that there is a slight Längsverschieblichkeit, but only one extremely low bearing clearance.

From the FIG. 2 It can be seen that in the attached state of the two housing cover 11, 12 in the interior corner 18, the arrangement is made such that the housing cover 12 is externally acted upon by a front side 21 of the housing cover 11 so that in the inner corner corner 18 of the housing cover 11, the housing cover 12th holds down. The consequence of this is that during production preferably only a single assembly order is possible, such that only the housing cover 12 and then the housing cover 11 is mounted.

The base housing 10 has two basic housing legs 22, 23. This is especially the FIG. 4 refer to. The basic housing legs 22 and 23 are designed to be open, ie they do not have the two housing covers 11 and 12.

As in particular the Figures 2 and 3 can be seen, the basic housing leg 23 on both sides each have a Einschiebleistenvorsprung 24. The Einschiebleistenvorsprünge 24 extend beyond the remaining contour of the angular housing 6. The Einschiebleistenvorsprünge 24 extend in the direction of the longitudinal extent (double arrow 25 in FIG FIG. 2 ) of the basic housing leg 23.

Furthermore, in particular the Figures 2 and 3 it can be seen that at least one, preferably two plug-in projections 26 are formed on the housing cover 11. The plug-in projections 26 extend transversely, in particular at right angles, to the longitudinal extent (double-headed arrow 27) of the associated housing leg 7.

The arrangement is preferably made such that the base housing 10 and the housing cover 11 and 12 are formed mounting vertproof, such that the housing cover 11, 12 can be fixed in each case only in one orientation and in each case only one position on the base housing 10. This assembly exchange security is achieved by projections 28 and recesses 29. The projections 28 engage in the finished Eckumlenkung 1 in the recesses 29 a. According to the FIGS. 1 to 4 are on the two housing covers 11 and 12, the projections 28 and the base housing 10, the recesses 29 are formed. The permutation safety during assembly results from the arrangement of the projections 28 or recesses 29, as in particular from FIG. 4 becomes apparent. The distances a, b, c, d, e and f recognizable there on the base housing 10 are designed such that a ≠ b ≠ c, b ≠ e and d ≠ e ≠ f. The distances a, b, c, d, e and f are defined as follows: a = distance between the end of the base housing leg 22 and the nearest recess 29, b = distance between the two recesses 29 of the base housing leg 22, c = distance between the corner area 4 and the adjacent recess 29 of the base housing leg 22, d = distance between the corner area 4 and the adjacent recess 29 of the base housing leg 23, e = distance between the two recesses 29 of the base housing leg 23 and f = distance between the end of the base housing leg 23 and The corresponding recess 29 are preferably located on both sides of the base housing 10, since there, so on both sides, recesses 29 are formed. Corresponding conditions are realized in the two housing covers 11 and 12 with respect to the projections 28 in order to make a suitable attachment to the base housing 10 can. The recesses 29 are preferably located on the two side angle walls 14 and 15; the projections 28 are preferably located on the longitudinal edges of the two housing cover 11 and 12th
