For the final locking of this well-known! Corner drive So holes and screw connections have to be drilled on the frame profiles be made. Even if the corner deflection body is attached to the fitting parts that are to be attached anyway is to be secured to the frame profiles it is in practice in cases in which, for whatever reason, the corner drive has to be removed afterwards always necessary to dismantle these hardware components. As a subsequent loosening of the hardware parts, e.g. as a result of a malfunction of the connecting rod, especially when it comes to hinges, as a rule A, however, it is also necessary to remove the entire window sash makes, the already considerable dismantling times for the corner drive are increased even further.

In the case of thin-walled frame profiles, such as those used primarily in light window designs intended for social housing occur, the mounting points, e.g. threaded holes, work their way through the material over time due to the high stress on the hardware components the frame profiles, so that in the long run the fittings and thus the corner drive loosen or even solve. This is all the more likely to result in the loads that have to be absorbed by the fitting parts anyway IP are further increased that the acting on the Eckumlenkkörper significant loads by the Drive rod actuation added — come.

Another essential part of this well-known Execution can be seen in the fact that the frame piOfile is used to insert the corner deflection body into the guide channel in the area of the miter cut the guide channel corners must be opened, which in practice by milling, filing, or parting. By such an additional work step during the honing the corner drive increases the installation times even more.

_Λ ^ _ΛΛ ^BAD ORIG / NAL

Starting from a corner deflection of the type mentioned at the outset, the invention aims to avoid the above disadvantages and one that is simple to manufacture and easy to assemble To create corner drive, no screws or other fastening elements for fixing them to the frame profiles are required. This object is achieved according to the invention in that at least one the engaging in / guide channel of the frame profiles Retaining elements of the corner deflection body in such a resilient manner at least on one of its two legs Is deformable that the corner deflection body in the guide channel of the frame profiles, detachable as a whole can be locked in its final operating position is. The corner deflection base (f body from one at least in the area of the resilient Retaining elements of elastically deformable material. Plastic is expediently used as the material. ! By the present According to the invention, it is possible to insert the corner deflection body in a simple manner, e.g. by hand, into the guide channel of the frame profiles, with which it is finally without additional screw connections to the frame profiles is fixed in its operating position. As a result of the resilient deformability of the holding elements unhooking the or the like at the ends of the chain guide. detachably attached "driving rods of the corner drive in the predominant cases even possible without the corner - ^ steering body completely out of the guide channel 'the ™

mechanical corner connection are interconnected. Particularly when a window is designed as a turn-tilt, tilt or pivot sash, so-called corner deflection is required for deflecting the movement of the connecting rods 5, 4. In the preferred exemplary embodiment shown in FIGS. 1 to 5, such an ecology steering is designated as a whole by 5 ". It consists in detail of a one-piece Eclcuialenliuiigs basic body 8 having two legs 6, 7 with lateral holding elements 9, between which there is a guide channel 10 for receiving and guiding a deflection link formed by a link chain 11 or the like. For a better understanding, it should be said that under ¹ the holding elements 9 are to be understood as part of the EckumlerQmngsgrundkörper 8, while the Eckumlenkungsgrundkörper 8 zu- "_;

Eckumlenkkörper results. The deflection body C is with its holding elements 9 in a designated 12 Maintained guide channel, which is molded into the frame profiles 1,2 and in its cross-section from each other directed, angled ends 13, lateral web parts 14 and the base 15 of the profile is limited. In the guide channel 12. are also the connecting rods 5 »4- des Corner adjustment fitting, slidingly guided.

According to the principle of the invention, the holding elements 9 of the corner deflection base body 8 engaging in the guide channel 12 are designed to be resiliently deformable in this way, M

that the corner element in the guide channel 12 of the frame profiles 1,2 as a whole, including the guide channel 10, is held in its final operating position releasably lockable .. To achieve this, the corner element consists of an at least in the area of the Haite elements 9 elastically deformable Material, preferably made of plastic. In the preferred exemplary embodiment selected in FIGS. 1 to 5, the holding elements 9 are each formed by a spring bar which is elastically variable in position transversely to the longitudinal axis of the associated leg 6, 7. '.

The spring bars 9 are designed so that they are when inserted of the corner deflection body into the guide channel 12 in the direction of arrow 16 (Fig. 3) automatically in the final Clip in the locking position. To the folding too facilitate and ensure the holder, the spring bars have protruding at their free longitudinal edges Auflauf- and locking cams 17, which cooperate with the angled ends 15 of the guide channel 12. In the example shown in Figures 1 to 5, each of the two legs 6,7 of the corner deflection body 8 two spring bars arranged approximately the width of the leg at a parallel distance from one another, but which are interrupted along their length. But you can also, depending on your requirements, continuously over the entire Extend leg length, as illustrated in the modifications shown in FIGS. 6, 8 and 10 is.

In the examples according to Figures 1 to 5 and. 6 to 9 it can be clearly seen that the plate-link chain 11 receiving, is located between the spring bars 9 »9 '» 9 " of the corner deflection body 8 extending guide channel 10 with the corner deflection body having the spring bars 8 forms an integrated one-piece part. But it is also possible to use the guide channel as a separate from the corner deflection body 8 Form component, as illustrated in the embodiment shown in Figures 10 and 11 is where the guide channel is given the reference number 10 ' Has. The disadvantage of this embodiment is that the corner deflection body consists of different individual parts there is what should be avoided if possible. For both versions, however, applies that according to the invention between the side flanges of the respective guide channel 10, 10 "and the mutually facing inner sides of the spring bars 9. There is such a distance that for the spring bars enough space for at least a temporary one Change in position when setting the corner deflection body in the guide channel 12 of the frame profiles 1,2 and remains when it is released.
