Abstract

Locking device for the wing of a window or door comprises sliding connecting rods (5) of fittings, i.e. a first fitting (20) optionally already arranged in a fitting groove and a corner deviator, which are detachedly coupled to each other via a deviating part. One of the fittings has a ramp on one end. Preferred Features: The ramp is connected to the corner or guiding channel of the deviator. The guiding channel interacts with a connecting rod of the other fitting.

Description

The invention relates to a locking device according to the Preamble of claim 1.

Such a locking device is from the layout DE 23 34 881 already known. This should be slidable in a frame and driving rods running perpendicular to each other via a deflection member be connected to each other. The deflection member is usually there from a band guided in a corner housing or a guide channel or ribbons, which at its ends indirectly or is or can be directly positively coupled to the drive rods. For coupling to the connecting rod of the adjacent, first fitting part according to DE 23 34 881 that the deflecting member indirectly via a Connecting rod of the corner deflection, which pulls with the deflection and is pressure-tightly coupled, a connecting pin for engaging in one Breakthrough of the drive rod of the first fitting part. It is on the connecting rod a leaf spring provided with the Connecting rod is longitudinally displaceably connected and in turn one of the Has connection pin to be assigned hole.

The drive rod of the first fitting part is special at its end provided guide pieces longitudinally displaceable but transverse to it held deflectable so that the drive rod when inserting the Corner deflection is first deflected until the connecting pin in the Breakthrough indented. Then the drive rod is between the leaf spring and the connecting rod is positively coupled in the direction of displacement.

It is easy to see that such an arrangement with special Leading parts entails a high manufacturing effort, since the Guide parts before installing the connecting rods on the wing or Frame must be mounted. At the same time, it is still not ensures that the corner drive and the drive rod of the fitting part can be safely coupled with each other, as with a blunt Do not knock the connecting pin against the drive rod can be deflected up or down.

The object of the invention is therefore a locking device to further develop according to the preamble of claim 1, that with a simplified structure of the locking device coupling of the hardware components is ensured as securely as possible.

This problem is solved with the characteristics of the characteristic Part of claim 1. This simple measure makes a blunt Beating the hardware components involved avoided and at the same time a targeted and easy deflection of the fitting part to be coupled causes. Such ramps can be relatively easily connected to the Provide fittings and also manufacture. The coupling of the fittings if only one of the fitting parts is effected with a simple movement, so that also automated assembly using suitable devices is possible.

A preferred embodiment provides that the ramp on the Corner housing or guide channel of the corner drive is attached. Thereby the first fitting part already attached to the sash or frame, which, depending on the hardware configuration, may not always have a Corner drive is coupled, still relatively simple while the ramp is only used when one appropriate coupling with a corner deflection is provided.

It is also provided that the guide channel is the drive rod of the other Engages under the fitting. This means on the one hand, on the other Fitting part no offsets or the like. The drive rod necessary and the As is known, the guide channel can be the drive rod of the other Fitting part covering cuff rail are covered.

It is further provided that the ramp at its tip end into one Radius passes. This is when installing the corner drive from This is a particular advantage, since this means that the ramp Fitting part without damaging the ramp and without scraping on the support other fitting part or attack it.

The design of the ramp with a tapering end provided radius prevents scraping and thus a connected higher displacement force of the corner drive and at the same time one Damage to the groove base of the hardware groove. Because the ramp is on attached to the corner housing or guide channel of the corner drive and at the same time an embodiment is provided in which the guide channel or Corner housing engages under the drive rod of the other fitting part, so supports the ramp at the bottom of a hardware groove when inserting what on the one hand the necessary deflection of the fitting part to be coupled relieved, but on the other hand scraping or rubbing the ramp on Cause the hardware groove could cause.

Another advantageous embodiment provides that the ramp on one Fastener is attached, which in the assembled state Guide the drive rod of the first fitting forms. This will accomplished that the ramp simultaneously aligns the drive rod contributes, thereby coupling the projection to the associated one Recess is facilitated. Because the connecting rod is smaller in width is dimensioned as the hardware groove it can be manufactured by the Driving rod as a stamped and bent part and an associated light Curvature of the drive rod to an offset position of the center lines of Drive rod and faceplate of the first fitting part come. This can cause the protrusion no longer in the associated recess penetrates or that the drive rod is too lateral when loaded Evasive movements is initiated. This is through the formation of the Reliably prevented leadership.

An advantageous embodiment of this last exemplary embodiment provides that to form the guide, the fastener has an elongated hole in the Driving rod of the fitting part by means of webs forming a screw guide be upheld. On the one hand, the screw guide places the faceplate and thus also the drive rod of the first one, which can be moved longitudinally Fitting part relative to the second fitting part, whereby by the Fixing the guide link on the wing or frame in the Fitting groove additionally guides the drive rod of the first fitting part is improved and secured. An engagement of the immediately subsequent coupling consisting of projection and recess thereby also avoided.

In order to deflect the fitting part as easily as possible perpendicular to It is intended to ensure displacement of the drive rod that the guide or screw guide of the fastener for the Drive rod of the other fitting part forms a continuation of the ramp.

It is also advantageous if the distance of the slot from the end the connecting rod is dimensioned somewhat larger than the distance of the Fastener from the projection. This ensures that the deflection during the entire assembly process of the already assembled fitting part takes place via the ramp and the Driving rod can then be supported on the fastener until the Projection for coupling in the recess overlapped by the drive rod becomes. Then move the fastener, leading the drive rod and aligning into the slot, the deflection of the fitting part caused exclusively by the projection, so that this when reaching the Recess due to the elastic properties of the already assembled fitting part can securely engage.

A particularly advantageous embodiment of the invention provides that the Drive rod of the already fastened fitting part below one at a distance is guided to the corner ending cuff rail. This opens up for example the possibility of a method according to DE 196 02 025 C2 apply. First, the loose bars of a frame are included the fittings and only then the loose bars to one Frame connected. However, it is necessary that the appropriate Fitting parts from the corner area, i.e. the connection point of the bars, remain spaced so that, for example, with plastic windows Processing of the resulting welding screw can be done.

Finally, it is for the function of the entire locking device still an advantage if a on the corner housing of the corner drive Cover plate for gripping over the faceplate of the first fitting part is provided. The faceplate of the first fitting part is relative fixed to the hardware groove without this being a special one Fasteners on the faceplate in the immediate end area must be provided. A fastener, such as a Fastening screw is only under weakening the deflection Attach corner deflection.

The wing frame shown in Fig. 1 consists of an upper horizontal frame leg 1, a lower horizontal Frame leg 2, a vertical frame leg 3 on the lock side and a hinge-side vertical frame leg 4. Das Embodiment is shown as an exploded view, the Individual parts are out of scale to each other.

The locking device is an espagnolette fitting with a Push rod 5, which is covered and guided by a faceplate 6. For this purpose, the connecting rod fitting is offset in a known manner Step groove of the sash rebate added. A not shown here, operating handle arranged on the lock side, available in different Different switching functions of the rotary positions Locking device sets, engages through a pinion Espagnolette drive 7, which depends on the position of the operating handle generates a longitudinal movement of the drive rod 5. Corner deflections 8.1, 8.2 and 8.3 steer the displacement movement of the drive rods 5 by 90 ° each adjacent frame leg.

So that the tilt and turn sash can alternatively be turned or tilt opened can, is on the hinge side on the lower frame - not shown here Tilt and turn bearing 9 and on the hinge side near the upper frame leg 1 a pivot bearing 10 is provided. On the pivot bearing 10 is a Ausstellkerlen an Ausstellvorrichtung 20 articulated. The one from the Frame legs 1 to 4 formed wing is over locking pin 13th by reaching behind latch interlocks fixed to the frame set against the frame. To fix the wing in the Tilt position engages the tilt lock 14 in the tilt bearing 12, so that the wing can be pivoted about a lower horizontal axis can, the opening arm 11 limits the opening width. In the The opening arm 11 is in the rotational opening position compared to the one with the 20th designated issuing device via the locking element 15 and in held parallel to this.

In addition to the components of the locking device already indicated, namely the drive rod drive 7, the corner drives 8.1, 8.2 and 8.3 and the opening device 20, 11 is an extension 19 provided that the tilt lock 14th in the illustrated embodiment wearing.

Fig. 2 shows the end of the faceplate 6 and the drive rod 5 of the Display device 20 and the corner deflection 8.3 in a first Assembly step. The opening device 20 is in a fold side in the Frame leg attached fitting groove 21, the Fastening, for example, using fastening screws or the like he follows. The attachment of the display device 20 is either on already assembled frame or on the top horizontal frame leg 1 before connecting it to the rest Frame legs 2, 3 and 4. To redirect the adjusting movement of the Driving rod 5 in the direction of displacement designated 22 is the Corner deflection 8.3 provided with a deflection member 23. The deflection member 23 consists of a guide channel 24 in the pressure-resistant one or Package of pressure-resistant tapes is guided longitudinally. This will the displacement movement of the drive rod 5 to the perpendicular to it redirecting section of the guide channel 24 and here to a - not shown here - further drive rod 5 transferred. To couple the Deflector 23 with the drive rod 5 of the opening device 5 is on the Band or bands 25 in the guide channel 24, a carriage 26 provided, which is guided in the guide channel 24 to be longitudinally displaceable. The Carriage 26 passes through the band or bands 25 of the deflection member 23 and protrudes over the rear of the guide channel 24 with a projection 27 in front. The projection 27 has the shape of a pin with flattened Pages and is dimensionally matched to one in the drive rod 5 Display device 20 bore 27.1. Is already in the Hardware receiving groove 21 mounted display device 20 the corner deflection 8.3 inserted in the fitting groove 21 and that along the direction of displacement 22 of the drive rod 5, the opening device 20 is perpendicular to 3, vertically upwards in the illustration according to FIG. 3, pivoted out of the fitting groove 21, the drive rod 5 and the Forend rail 6 of the opening device 20 initially by means of the ramp 28 the edge 29 of the guide channel 24 can be lifted. The ramp 28 rises Sliding direction 22 and causes the drive rod 5 to be raised to the extent that the guide channel 24 can reach under the drive rod 5. Though is the drive rod 5 in the installed state of the opening device 20th already spaced from the bottom 31 of the fitting groove 21, but is about a generously dimensioned and at the tip end of the ramp 28 provided radius 32 a butt against the ramp 28 avoided the lining edge 30. The radius 32 also sits on the Underside, ie the surface facing the bottom 31 away, so that the Ramp 28 can not scrape at the bottom 31 of the hardware groove 21.

The ramp 28 is attached to a fastening member 33 which the guide channel 24 against the base 21 so far that the Carriage 26 can be moved without contact to the bottom 31. The Fastening member 33 extends through the guide channel 24 with two projecting webs 34.1 and 34.2, which together a Form screw guide, as will be explained with reference to FIG. 6. The Web 34.1 has part of the screw guide of the fastening member 33 a continuation of the ramp 28, in which the 22 lying part of the web 34.1 is provided with a bevel 35. Thereby the drive rod 5 together with the faceplate 6 still further pivoted until the drive rod 5 on the blunt top 36 of the webs 34.1 and 34.2 comes to rest.

If the corner deflection 8.3 is now moved further, this supports Fastening member 33 on the webs 34.1 and 34.2, the drive rod 5 and Face plate 6 until it is in the area of an elongated hole 37 Drive rod 5 come to rest. Here is a support of the Drive rod 5 and the faceplate 6 but also guaranteed because of clear distance of the fastening member 33 - here the web 34.2 - and Projection 27, namely the dimension 38, is slightly less than the smallest Distance 39 of the elongated hole 37 to the front edge 30 of the drive rod 5. Thereby the drive rod 5 initially sits exclusively on the webs 34.1 and 34.2 on which protrude the projection 27, but at least until the Projection 27 in the event of a further displacement of the corner deflection 8.3 engages under the drive rod 5. If the corner drive is relocated 8.3 the drive rod 5 is now supported exclusively on the projection 27, until this due to the elastic tension of the end portion of the Cuff rail 6 and drive rod 5 engage in bore 27.1. there springs the faceplate 6 and the drive rod 6 of the opening device 20 so far back that this is completely included in the fitting groove 21 be and the top edge of the faceplate 6 almost flush with the fold of the wing.

This mounting position is shown in FIG. 5, from which it can be seen that the drive rod 5 of the opening device 20 in the slot 37 both from the ramp 28 and from the webs 34.1 and 34.2 is reached. The webs 34.1 and 34.2 are dimensioned such that this the faceplate 6 of the opening device 20 with respect to the groove base are able to support, if a fastening screw by a - invisible - drilling the faceplate, which the Fastening member 33 engages in the bore 39. The fastener 33 is for better support of the guide channel 24 on its base 31 the hardware groove 21 side formed large area.

As can still be seen from FIG. 3, the faceplate 6 ends Display device 20 at a distance 40 from that indicated here Sash rebate edge 41. The corner deflection 8.3 in turn has a bent Leg 42 of a faceplate or corner housing 43, the length of which is dimensioned somewhat smaller than the distance 40 the direction of displacement 22 an open edge opening 44 is provided which a web 45 of a cover plate 46 is penetrated. The cover plate 46 is over the web 45 and over one below the leg 42 extending connection 47 with a U-shaped bent end 48 connected, which has a window-like opening 49 of the leg 50 be upheld.

In the first displacement position of the cover plate 46 shown in FIG. 2 the end 48 over the leg 50 before. Pressing the end 48 this shifted in the direction of the display device 20, so covers the Cover plate 46 the gap 51 shown in Fig. 5 between the Faceplate 6 and the leg 42 of the faceplate 43. To secure the Position of the cover plate 46 is on the lower leg 53 of the U-shaped End 48 provided a downwardly protruding locking tongue 53, which after the shift to the second final shift position on the inside 54 of the leg 52 locked.

6 shows the fastening member 33 on an enlarged scale the details of the construction of the fastener 33 are apparent. The Fastening member 33 is a molded part, for example made of die-cast zinc inexpensive to manufacture. It can be seen that the radius 32 in the Ramp 28 merges, but also forms a transition to bottom 39. This allows 8.3 when moving the corner drive at any time a scraping or chafing of the fastener 33 on the bottom 31 of the Hardware groove 21 can be avoided. Form the webs 34.1 and 34.2 together a screw guide 54 which is coaxial to the bore 55 runs. The fastening member 33 is also in the region of the bore 55 projecting wings 56 through which the surface of the bottom 39 is enlarged and better support of the guide channel 24 is achieved. It can also be seen that the width 57 of the ramp 28 and the Width 58 of the webs 34.1 and 34.2 correspond approximately to one another, so that both the ramp 28 and the webs 34.1 and 34.2 for guiding the Driving rod 5 can reach through the elongated hole 37. When introducing the Corner deflection 8.3 is an alignment of the webs 34.1 and 34.2 Driving rod 5 causes so that this in an approximately longitudinally parallel Alignment to the faceplate 6 is held. This goes without saying supported by the already mentioned design of the webs 34.1 and 34.2, the protrude slightly further than projection 27.

Finally, it should be noted that the proposed Coupling of course also on other wing corners - deviating from 1 - can be made.

It can also be seen that the coupling of the corner deflection 8.3 to the Fitting part (e.g. the opening device 20) completely without pivoting movement he follows. A simple one is therefore sufficient for assembly and coupling rectilinear movement. This facilitates both a manual as well an automated fitting assembly on the sash. Especially with the automated fitting assembly carries out the proposed interpretation of Locking to significantly simplify the assembly system.

Contrary to the embodiment proposed in the exemplary embodiment Of course, it can also be proposed that the 8.3 corner drive Display device 20 engages. Even then is the use of the invention of Advantage, since the elastic restoring force necessary for the coupling of the Issuing device 20 goes out and to a protrusion, in the direction out of the hardware groove.
