Description

The subject of the innovation concerns an espagnolette fitting with a Corner deflection according to the preamble of claim 1.

Retaining elements for position fixing of espagnolette fittings are in one Numerous designs known.

DE 81 17 338 U1 discloses a device for fastening a Face plate and for guiding a drive rod in an open groove Wing. The device consists of a U-shaped holding member that on the one hand with the outer sides of the free legs of the U cross section abuts the side walls of a stepped groove, on the other hand with the ends the leg has lateral edge recesses of those covering the groove Grips the faceplate and by means of barb-like retaining projections this latches. On the outside of the free legs are in the longitudinal direction extending barb-like claws are provided, which adhere to the Create side walls of the groove and make it difficult to detach it from the groove. On the free end of the legs are outwards - towards the side wall the groove facing flanges attached, which are in the assembled state of the Support the holding member and the faceplate on the groove and thereby loosen prevent the tabs. At the same time there is one in the holding member Guide for the one that is mounted under the faceplate and can be moved lengthways Driving rod provided.

From FR 2 414 606 a U-shaped holding element is also known, which overlaps a cover of an espagnolette fitting. The free U-legs are driven into the bottom of the groove, so that these Only use holding elements for sashes made of wood. The free legs have barb-like protruding outwards Projections on the unwanted removal of the holding element prevent.

A configuration similar to FR 2 414 606 can be found in DE-PS 1 222 821 and DE 66 09 102 U1. L-shaped or U-shaped bracket-like holding elements over the faceplate or drive rods put up and driven into the solid material. An escape of the Retaining elements is also by acting against the direction of penetration Prevents barbs.

It is also known from AT 294 622, fitting parts without additional Fastening devices on the spars of a wing or a window to install. For this purpose, there are lugs behind a recess provided that is attached to a resilient tongue and barb-like when the fitting part is pushed in with the handle. This design therefore presupposes the presence of a recess or an undercut ahead.

From DE 24 07 196 C1 a holding element is known, which in addition to other fasteners such as screws is provided. To a This is to prevent the drive rod fitting from shifting in the groove Holding element provided with side serrations that match the Lay the side walls of the hardware groove. Moving the fitting is prevented while relieving the fastening screws.

A U-shaped holding element is also known from EP 0444 405 B1 become, which reaches through the lateral edge recesses of the faceplate and dips into the groove with its free legs. The thigh reach through recesses or recesses in the wing profile and thus prevent the fitting from shifting lengthways.

From DE 31 01 393 C2 it is known to have a U-shaped holding element provide that its U-legs extend to the bottom of the groove and from the U-legs laterally projecting tongues behind the webs of the hardware groove to grab. The U-legs are matched to the groove geometry so that the U-legs when inserting the holding element between the webs are feasible and the tongues after reaching the bottom of the groove snap on the outside behind or under these, while at the free end of the U-shaped claws penetrate into the groove base and one Prevent longitudinal displacement. The holding element is therefore on the Coordinate groove dimensions and can only with undercut grooves Find use.

Both from DE 196 46 988 A1 and DE 296 19 198 U1 is a Fitting known that a holding element for temporary attachment provides a faceplate. For example, in DE 196 46 988 A1 U-shaped holding element known from DE 31 01 393 C2, at which the U-legs are divided in the longitudinal direction and different heights exhibit. The U-legs can therefore either behind the webs of the groove lock or frictionally on this or the side wall of the groove issue.

In a second embodiment of DE 196 46 988 A1 that is Holding element in a laterally open area of a corner drive arranged. The holding element clamps between a guide channel and a faceplate designed as a cover bracket and stands like this on the side via the guide channel that the desired clamping is achieved. The Holding element is either expensive to attach, because that Holding element could slip during rough transport, or with one high clamping force between the components. A slipping of the Holding element can not with a frictional connection be excluded.

DE 296 19 198 U1 sees as a holding element on the side of the faceplate protruding cutting teeth, which are during assembly in the area of Have the faceplate pressed into the groove side walls. This temporary fixation of the fitting is used to simplify the Assembly provided. Depending on the material of the wing, the Cutting teeth but only with an additional tool in the Drive in the wing material.

The invention is therefore based on the object of being expedient Design of the holding element and the corner drive to meet the on the one hand contributes to the fixation of the corner deflection, on the other hand easy and uncomplicated to assemble. The assembly of the holding element Like the corner deflection on the sash, this should be done without tools the holding element is equally suitable for all wing materials should be.

This object is achieved with the features of claim 1 solved.

It is particularly advantageous that the holding element designed in this way also at a later time, for example by the fitter of the Corner drive, can still be attached. The bracket can be used as Comparatively easy to manufacture component but also according to the Be prepared for later use for assembly different groove dimensions. But it is also advantageous that the Holding element after attachment to the cover bracket almost captive connect with it. The lateral edge recesses are from A particular advantage, as it is often used in the manufacture of the wing corners Remnants of material remain. The corner area of the wing is after the Assembling cleaned by so-called cleaning machines, However, residues cannot be avoided, so that it is Introducing the corner redirection to the undesirable because it cannot be calculated Clamps is coming.

This fact is made more difficult by the fact that the material of the Cover angle of the corner deflection bulges slightly outwards in the bending area or dented. This is prevented by the side edge recesses. The bracket uses these edge recesses for fastening and Reach out with the webs.

Another advantageous embodiment provides that the legs of the Brackets run along the bisector. The bracket can thereby easily inserted and the thighs get a maximum Length.

Easy installation on the cover bracket and on the frame profile is guaranteed, if the legs have inward and outward projections have, with the inward-pointing projections with the cover angle interact and the outward projections on the Side walls of the groove are sufficient.

If the bracket covers the edge recesses, there is not only one good visual impression. It also prevents dust and / or Cleaning agents penetrate the openings and the fitting or the window can damage.

A simple, because confusion-proof installation is guaranteed if the Bracket is designed symmetrically to the bisector.

For better optics of the clip it is also provided that the clip and the cover angle have almost the same width, the web being the Side with a thickness corresponding to the thickness of the cover angle surmounted.

In addition to the function of the clamp, the clamp can be closed when the Interact wing with a frame-side cage or trestle. The Bracket fulfills the task of a wing-side casserole, which, since close arranged on the wing edges, for lifting the front wing edge serves.

The clip is on the outside as an advertising or Information carriers can be used.

A particularly cost-effective production is guaranteed if the Bracket is a molded plastic part. This also means that desirable elastic properties of the clip achieved.

Another useful embodiment provides that the cover angle in Corner area at least in sections perpendicular to the bisector runs. The clip can thus be a triangular shaped body in cross section fill the gap in the cover angle and at the same time fill in the Effect clamping. This measure can shorten the cover angle become.

An alternative provides that the cover angle in the corner area has a radius having

another embodiment of a cover bracket and the bracket.

The corner deflection 1 shown in FIG. 1 consists of a cover bracket 2, an angular guide channel 3 for a flexible deflection member 4, and one or two drive rods 5, which pull over the deflection member 4 and are rigidly connected to one another and by guide pieces 6 are slidably attached to the cover bracket 2. The drive rods 5 are for coupling with adjacent fittings with coupling shoes 7 Mistake. At the corner deflector locking members 8 can be provided interact with latch interventions on the frame, not shown. To the Cover brackets are for coupling to the faceplate or cover rails adjacent fitting parts overlap connections 9 are provided. The Cover angle 2 is by means of holes 10 in the area of the guide pieces 6 of additional fastening screws can be pushed through and on the casement profile connectable. The cover bracket 2 at least covers the fitting receiving groove.

In the corner area of the cover bracket 2, which is shown enlarged in Fig. 1a, is a holding element in the form of a bracket 11 is attached to the cover bracket 2. to Avoidance of the circumstances already specified in DE 296 19 198 U1, namely that the corner drive 1 must be held during assembly In order to prevent the component from slipping, the holding element is used temporary fixation of the corner drive 1 on the wing until the Fastening screws have been attached.

The bracket 11 fixes the corner deflection by form and / or friction with the groove side walls of the fitting groove. There is also Holding element from the angular and cross-sectionally U-shaped bracket 11, the side edge recesses 16 of the U-leg 15 of the Cover angle 2 passes through and on the side walls of the below the Cover bracket 2 horizontal fitting groove protrudes. The side Edge recesses 16 are in the corner area of the cover bracket 2 on both Legs 17,18 of the cover bracket 2 arranged so that at least the Corner area is designed symmetrically (Fig. 4). The web 19 of the bracket 11 lies flat on the cover bracket 2 without space.

As is particularly clear in connection with FIG. 3, the Edge recesses 16 of the legs 15 at least partially engaged behind. For this purpose there are locking projections 20 from the legs 15 inside each other. These snap into place when the clamp 11 is installed the back of the cover bracket 2.

As shown in FIGS. 1 to 3, the legs 15 run along the bracket 11 the bisector 21. As a result, the legs 15 reach into the free space 22, which lies between the cover bracket 2 and guide channel 3. This arrangement ensures problem-free insertion of the corner drive 1, which at Assembly also performed along the bisector 21 of the wing becomes.

The legs 15 have inward and outward projections 20.25, the inward-pointing projections 20 with the - here indicated-cover angle 2 interact. The ones pointing outwards Projections 25 on the side walls of the groove - not shown here pass. Since the legs 15 are at least limited due to their dimensions are elastically deformable, the projections 25 lie under one depending on Execution of the fittings receptacle large deformation of the legs 15 to the side walls of the groove. However, it is advisable to use the bracket 11 made of an elastic material, e.g. Plastic. Especially The embodiment shown as a plastic injection-molded part is advantageous in addition to cost-effective production, the necessary Material properties guaranteed.

To get a closed fitting surface, the bracket covers 11 the edge recesses 16. The penetration of dust and dirt or detergent is prevented. If the width 26 of the The bracket 11 corresponds approximately to that of the cover bracket 2 can also be used with grooves whose groove level is dimensioned lower than that Thickness 27 of the cover bracket 2 (Fig. 1a). At the same time, the bracket 11 is not over the cover bracket 2, so that the storage of the with the clamps 11th provided corner deflections 1 can be made to save space. It it is useful that the bracket 11 and the cover bracket 2 is almost have the same width 26, the web 19, the legs 15 with a Thickness 28 corresponding to the thickness 27 of the cover bracket 2 protrudes laterally. As a result, the lateral edge recess 16 is closed or covered. At the same time, the legs 15 are also larger Cross section tied to the web. The achievable spring force is thereby maximized and increased the strength of the entire bracket 11.

The bracket 11 is designed symmetrically to the bisector 21, such as emerges in particular from FIG. 2. The bracket 11 can therefore Attach to the cover bracket 2 as desired, without paying attention to an orientation must become.

In addition to the function of fixing the corner deflection 11, the bracket 11 but also others that support the functionality of the fitting Functions can be assigned. So the bracket 11 can be dimensioned be that this when closing the wing with a frame-side Casserole or goat interacts. The casserole is used for lifting of the wing on its front wing edge when closing to a sagging to compensate for the wing. At the same time the between wing and The space between the frames is narrowed, which makes for security against break-ins is important. Because the bracket 11 on both the top and the wing cannot be attached to the lower edge of the wing lift more out of the locking interventions.

Furthermore, the bracket 11 on the outside as an advertising or Information carriers can be used. On the outer flat surface of the web 19 any imprints or similar be attached.

Fig. 4 shows the cover bracket 2 without bracket 11. The side Edge recesses 16 are longitudinally symmetrical and, with respect to the Bisector 21, also arranged transversely symmetrically. The cover bracket 2 is therefore tapered in the immediate corner area. This rejuvenation is from the bracket 11 almost completely filled. The bracket 11 is in Contrary to the angled cover bracket 2 in the corner area with vertical ones Provide boundary edges. The cover angle 2 bulges at Bend outwards so that a groove narrowed during assembly, e.g. by protruding beads during butt welding, inserting the Corner deflection 1 difficult.

The exemplary embodiment provided in FIG. 5 provides that the cover angle 2 in the corner area at least in sections perpendicular to the bisector 21 runs. The cover angle 2 is in this area on the width of the Guide channel 3 tapers through the lateral edge recesses 16. The Clip 11 - shown here only schematically - can the edges of the Edge recesses 16 both at the longitudinal ends 30 - at the Legs 17, 18 - or reach behind on the transverse edges 31. Of course, the latching of the webs 15 can also be carried out at all of these locations respectively. The clamping effect of the bracket 11 is not below the Cover angle 2, but above - on the cover angle 2 - instead. The For this purpose, bracket 11 is attached to the triangular surfaces 35 Spring tongues 36 are provided, which are resiliently elastic on the bracket 11 are intended to cooperate with the groove side walls. It can additionally a spring element acting between the spring tongues 36, e.g. a compression spring may be provided. This can already be made in one piece with the Bracket be formed and for example as an arcuate Spring element lie inside the bracket 11.

The advantage of this configuration lies in the material savings of the cover angle 2, which can be shortened. On the other hand the guide channel 3 in the arch supports, which is advantageous for production is. The clip 11 can be particularly simple in this embodiment assemble and attach.

However, the cover angle 2 can also have a radius in the corner area that is adapted to the radius of the guide channel.

The lateral edge recesses 16 serve in both embodiments for tapering the cover bracket 2 so that it can be inserted into the fitting receptacle can immerse.
