The invention further relates to an angular coupling element for a such corner connection and a fitting system with such Corner connection.

It is a hardware system for swivel or swing-tilt sashes known from windows or doors, between two fittings of the Fitting system, which converge on a corner of the wing, one provide detachable corner connection. Such a corner connection has two provided on the two fittings to be connected Coupling elements, the first coupling element being a hook element has that with a recess formed on the second coupling element can be brought into engagement. To the provided on the fittings To hook the coupling elements together, the two coupling elements must are moved towards each other by a rotary or tilting movement, wherein the hook element is pivoted into the recess. At the same time with this rotary movement one on the two fitting parts provided, power-transmitting coupling connection, which is provided, for example, as a hole-pin connection on the fitting parts is. To release the hardware components, these must be reversed Rotation or tilting movement can be moved relative to each other, so the hook element comes out of engagement with the recess and the coupling connection is released.

The object of the invention is a releasable corner connection for a fitting system or an angular coupling element for such To provide corner connection through or by its use the joining of two to be coupled together in a corner area Hardware parts of the hardware system is simplified.

The invention solves the problem by a corner connection with the features according to claim 1 and in particular in that the hook element an at least partially resilient one on the first coupling element Locking hook is the one for connecting the two fittings together can be locked with the recess on the second coupling element. Further the task is achieved with an angular coupling element Features according to claim 10 or by a fitting system with the Features solved according to claim 17.

In the invention, the two fitting parts of the fitting system connected to each other in the corner area by the on the coupling element of the a fitting part provided resilient locking hook with the on the coupling element of the other fitting part trained recess. For this purpose, the latching hook and the recess are at least in one approximately linear movement towards each other until the locking hook comes into engagement with the recess, while the Elements of a possibly formed on the fitting parts Coupling connection to be coupled together. Because of the very simple sequence of movements while connecting the Both fittings can also be used in an automatic assembly machine can be locked together using only a simple linear drive disposes. To release the corner connection, the resilient Snap hooks of one coupling element can only be bent briefly, so that it comes out of engagement with the recess, and then the fitting part provided with the locking hook in one of the joining direction opposite linear movement are subtracted, taking the elements the coupling connection that may be provided between the fittings are completely detached from each other.

Further advantageous developments of the invention result from the following description, the drawing and the subclaims.

So it is particularly advantageous if the resilient locking hook of the first Coupling element approximately parallel to the longitudinal direction of the first fitting part can be deflected to latch. The fitting part provided with the locking hook will then latch approximately across its longitudinal direction moves with respect to the second fitting part, so can already before Lock in its final assembly position aligned with the casement or be mounted so that a subsequent readjustment of the first fitting part on the sash frame after locking with the second Fitting part can be omitted.

To lock the first coupling element with the second coupling element to facilitate, it is also proposed to the first coupling element one running at least approximately in the direction of the locking hook Form nose, which together with the locking hook an insertion funnel forms for the second coupling element. As soon as the second coupling element comes into engagement with the insertion funnel during the joining process, it is inserted into its resting position by the insertion funnel during the joining movement performed so that any existing position tolerances or inaccuracies be balanced during the locking. So with this Embodiment a possible overload of the Locking hook is avoided, it is also proposed to both To form an elevation on the side of the latching hook on the first coupling element, which further limits the insertion funnel.

In a further preferred embodiment, the nose of the first runs Coupling element inclined at a preferably right angle to the longitudinal direction of the first fitting part, the nose with one of the End faces of the first fitting part approximately flush and with this forms a corner closure, the risk of possible injury prevented at the transition between the two fittings and the gives the corner connection on the fittings a pleasing appearance.

The first coupling element is in a preferred embodiment Corner connection formed as a separate component by a fastener is attached to the first fitting part. Through the separate Formation of the coupling element can the coupling element to different Fitting parts of the fitting system, such as a connecting rod fitting, be attached, which gives a particularly high flexibility and achieve a wide range of variants in the manufacture of hardware components leaves. Furthermore, retrofitting is required if the coupling element is designed separately Existing fitting systems possible without any problems, provided that on the second coupling element one for locking with the locking hook of the first recess is provided suitable recess.

The second coupling element is preferably as over the free end of the second fitting part protruding coupling nose formed in the Flat side the recess is provided. The recess is advantageous formed as a hole, the easy release of the locking connection between the locking hook and the bore allows by a suitable tool for easy prying of the locking hook through the Bore of the second coupling element is inserted.

For a corner connection of the type described above is particularly suitable an angular coupling element as specified in claim 10 is, in which the at least partially resilient locking hook together with the insertion funnel, which is designed as a nose forms for the further coupling element.

In this embodiment of the coupling element, the resilient Snap hooks can be integrally formed on the first angle section, with which the coupling element can be fastened to the fitting part, so that with appropriate Choice of materials for the coupling element, such as one Plastic, the production of the coupling element with little effort is possible.

Alternatively, it is proposed to use the resilient locking hook as a separate one Form component that at the first angular portion of the coupling element is attached. With a separate design of the locking hook can Use of the same base body for the coupling element during the Manufacturing different locking hooks are attached to the coupling element, so that a correspondingly large variety of variants in the design of the coupling element is possible.

A through opening 32 is provided in the first leg 30, to the bore 24 in the first angle section 14 and to one Opening 34 aligned in the faceplate 12 of the drive rod fitting is. Through the opening 34 in the faceplate 12 and through the Through opening 32 in the first leg 30 of the locking hook 28 is a Thrust pin 36 guided in the bore 24 of the first angular section 14 is riveted and with a collar 38 on the coupling element 10 facing facing surface of the faceplate 12 supports. At mounted window or door comes the stop pin 36th when closing the window or door with an appropriately designed Sheet metal engages on the window or door frame, the window or the door is raised slightly.

The first leg 30 of the locking hook 28 goes into a right angle this extending second leg 40 over that through the recess 26 of the recess 22 protrudes. The second points near its free end Leg 40 is a partially punched-out serving as a hook section Tongue 42, which is bent towards the free end and one Starting slope forms. On both sides of the second leg 40 of the Latching hooks 28 are on the flat side facing away from the faceplate 12 of the first angular section 14 two hill-shaped elevations 44, of which only the one arranged behind the latching hook 28 in FIG. 1 Survey 44 is shown. The surveys 44 go up with their about Height of the second leg 40 extending front sides in the recess 26 of the first angular section 14 via.

The end of the first angular section shown at the bottom in FIG. 1 14 formed second angle portion 16 has near its free end on its flat side facing the latching hook 28 a bevel 46, which is approximately mirror-symmetrical to the bent tongue 42. The second angle section 16 forms with the second leg 40 of the latching hook 28 and the two elevations 44 an insertion funnel 48, the Purpose will be explained later.

On the flat side of the second angular section facing away from the latching hook 28 16 an approximately rectangular plate section 50 is formed. The Plate section 50 forms a circumferential at the second angle section 16 Paragraph, which, among other things, in the direction of the faceplate 12 protrudes the first angle section 14 with the visible side of the Cuff rail 12 is flush and with this a rounded Forms corner.

In Fig. 2, a corner deflection 60 is shown, which is not shown Pin with a hole (not shown) on the drive rod of the Espagnolette fitting 13 is coupled during assembly.

The assembly is described below with reference to FIG. 3 of the drive rod fitting 13 with the corner deflection 60 explained in more detail. For plugging together the first coupling element 10 of the connecting rod fitting 13 and the second coupling element 66 of the corner drive 60, the corner drive 60 is initially either on the casement pre-assembled or clamped in a defined position. Then will the espagnolette fitting 13 with its faceplate 12 so aligned that the faceplate 12 with the insertion funnel 48 of the first coupling element 10 approximately at the level of the coupling nose 66 of the second coupling element 64 is arranged. Then the espagnolette fitting 13 in Longitudinal direction of the faceplate 62 of the corner drive 60 moves, wherein the coupling nose 66 of the coupling element 64 into the insertion funnel 48 of the first coupling element 10 is introduced. Through the relative movement the coupling nose lifts between the two coupling elements 10 and 64 66 the second leg 40 of the locking hook 28 slightly, like 3, wherein the latching hook 28 is mechanically pretensioned. With the continued insertion movement of the coupling nose 66 in the The insertion funnel 48 finally comes with the tongue 42 of the locking hook 28 the through hole 68 of the coupling element 64 engages, whereby the corner drive 60 is detachably connected to the connecting rod fitting 13 is. At the same time with this assembly movement comes the corner deflection 60 pins provided with the drive rod of the drive rod fitting 13 trained hole engaged. The covers Plate section 50 of the second angle section 16 the corner connection between the connecting rod fitting 13 and the corner deflection 60 that a corner finish is formed with a pleasing appearance.

As can also be seen in FIG. 3, the cranked course of the Coupling nose 66 between the plate section 50 and the visible surface a small gap 70 is formed in the faceplate 62 of the corner deflection 60. To the snap connection between the espagnolette fitting 13 and if necessary, the corner deflection 60 can be opened again with the aid of a Tool that through the gap 70 and the through hole 68th is introduced, the locking hook 28 are raised so far that the Coupling nose 66 are pulled out of the insertion funnel 48 again can.

As in the first embodiment, the coupling element 80 has a first angular section 84, which rests with its one flat side on the back of the faceplate 82 and a second angular section at right angles from one end thereof 86 protrudes, which points away from the faceplate 82.

On the flat side of the first angled section which rests on the faceplate 82 84, a depression 88 is formed, which is on the left in FIG. 4 illustrated end of the first angular section 84 is open. In the recess 88 protrudes in one piece with the first angle section 84 Rivet pin 90, which is formed by a in the faceplate 82 Bore 92 extends and for example by riveting the faceplate 82 is firmly connected.

Adjacent to the rivet pin 90 is a continuous one in the recess 88 Recess 94 formed that on the face plate 82 facing away The rear of the first angle section 84 ends and the depression 88 connects to the back of the first angle section 84. In the recess 88 is a locking hook 96 is used, the structure of which is essentially the structure of that used in the first embodiment Latch hook 28 corresponds. Here, too, is on the first leg 98 of the locking hook 96 a through opening 100 is formed with which the latching hook 96 is pushed onto the rivet pin 90. The second leg 102 of the locking hook 96 protrudes through the recess 94 and points to it free end of a tongue 104 which forms a hook portion.

On both sides of the second leg 102 of the locking hook 96 is in each case a hill-like elevation 106 is formed, of which, however, in FIG. 4 only the elevation 106 arranged behind the locking hook 96 is shown is. As in the first embodiment shown in Fig. 1, run here too the front sides of the elevations 106 are approximately flush with the front side of the second leg 102. The one on the right in FIG. 4 End of the first angular section 84 formed second angular section 86 has on its side surface facing the latching hook 96 a slope 108 and forms with the locking hook 96 and the two Elevations 106 an insertion funnel 110.

The coupling element 80 according to the second embodiment is also coupled with the corner drive 60 shown in FIG. 2, such as is explained below with reference to Fig. 5, which in this Case reversed, i.e. rotated by 180 ° around the longitudinal axis of their Face plate 62, is attached to the casement.

Here too, when installing the hardware components of the hardware system Corner drive 60 either already on the casement of the window or the door pre-assembled or as a separate component with the connecting rod fitting coupled. To lock the two fittings, the Espagnolette fitting for corner deflection 60 positioned such that the Insertion funnel 110 of the coupling element 80 to the coupling nose 66 of the Coupling element 60 is aligned. Then the espagnolette fitting evenly moved to the corner drive 60, the Coupling nose 66 is inserted into the insertion funnel 110. Doing so the coupling lug 66 to the locking hook 96. Will the espagnolette fitting Moving further in the direction of the corner drive 60, the tongue comes 104 of the locking hook 96 finally with the through hole 68 in Engagement, whereby the connecting rod fitting with the corner drive 60th is releasably connected, as shown in Fig. 5. It comes at the same time the pin provided on the corner drive 60 with one on the Drive rod of the drive rod fitting engaging hole, to couple the corner drive 60 to the drive rod. In this case forms the second angle section 86 with the faceplate 82 of the Espagnolette fitting and with the faceplate 62 of the corner drive 60 a corner finish, which gives the corner connection a pleasing appearance and by the risk of injury at the transition point between the two fitting parts is reduced

In this embodiment, too, is in the locked state between the second angle section 86 and the faceplate 62 of the corner drive 60 a gap 70 is formed through which with the aid of a tool (not shown) the latch hook 96 raised to release the latch connection can be.

In the exemplary embodiments described above, an espagnolette fitting was used coupled with a corner drive. Of course leaves the corner connection according to the invention also for connecting others Use hardware components. Furthermore, the corner connection can also be used for connecting of fittings used under another Angles run as 90 ° to each other.

It is important that there is an approximately linear coupling, since either the vertical or horizontal fitting part of the espagnolette fitting in the stepped groove of the casement not shown here is pre-assembled and because the force-transmitting, positive Coupling connection (hole-pin connection of the not shown Drive rod and corner deflection) no dimensional freedom gives.
