Description

The invention relates to a fitting for a window or a door, in which a locking element is provided for engagement with a locking engagement in a sliding direction running along a fold and, in its closed position, engages in a laterally open locking slot of the locking engagement running along the fold, the locking element At the transverse edge of the bolt engagement opposite the bolt slot, a stationary stop with a small distance is assigned.

Such a fitting is already known from the brochure Titan AF - Register 7, Titan AF stop instructions WK 2 PLUS from August 2010. The stop instructions are assembly instructions for the fittings and provide information about the arrangement and the required fittings. The installation instructions are provided to window builders and hardware retailers in order to be able to make a suitable choice of fittings.

The known fitting is a connecting rod fitting and has a deflection BS (item 44b, 12b) on the hinge side and on the second wing, which is coupled to an opening device at the upper end and has locking elements in the form of mushroom-headed pegs. These are moved by drive rods of the fitting along the fold of the sash and are assigned locking interlocks in the locking position, which are fixed in place on the frame rebate. The locking elements (items 50, 18) have two locking slots opposite each other in the longitudinal direction. The espagnolette fitting with the mushroom head pin engages in one of the locking slots. The transom parts are essentially designed to be longitudinally symmetrical to ensure that they can be used on right and left sashes as well as all spars of the frame. A locking engagement is assigned to a locking element on the hinge side. On the opposite side of the bolt engagement, a U-shaped anti-lifting device (item 47, 15) is arranged on the faceplate of the deflection BS, which acts as a stop. This is attached to the faceplate with a bayonet lock. The anti-lift device has two main effects. The distance to the locking element is chosen to be so small that even with a slight relative displacement of the sash relative to the frame, the anti-lift device is in contact with the locking engagement. This prevents a typical attempt in the event of a break-in to pry the locking element assigned to the locking engagement out of the locking engagement. The locking engagement lies between the stop and the locking element. A second effect of the attack is that the available rebate clearance, that is, the distance from the frame rebate to the sash rebate is narrowed, which fundamentally complicates the relative displacement of the sash to the frame. The stop cannot absorb forces introduced perpendicular to the sash or frame level.

From the EP 2143859 A2 is a fitting in which a second drive rod is associated with a first drive rod, which is coupled to the first drive rod via a gear. The second drive rod is coupled to the gearwheel by means of a coupling rod, so that an oscillating movement of the second drive rod occurs, so that a locking pin fastened thereon and a locking pin opposite this - based on a locking engagement located between them - dip into the locking engagement on both sides. This allows locking with both locking pins in a single locking engagement. A relative movement of the wing with the intention of forcing the locking pin out of the locking engagement leads to the second locking pin engaging even more deeply in the locking slot. A disadvantage here is the comparatively complex design.

The DE 19856451 C2 provides a locking pin and a swivel bolt in a construction with a similar effect, which are arranged on both sides of a bolt engagement and engage in the drive rod-controlled manner. Here, too, the arrangement is comparatively complex and must be moved every time the drive rod fitting is actuated.

From the DE 10111903 B4 a fitting is known which provides oppositely drivable and locking locking pins which engage in oppositely aligned striking plates. This requires push direction reversal devices and the number of bolt engagement elements to be provided increases, which increases the assembly effort and the number of components. The object of the invention is, based on the prior art mentioned at the outset, to make an improved configuration which is easy to assemble, does not impair the normal operation of the fitting, but improves security in the event of an attempted break-in. To solve this problem, a stop opposite the locking element on the transverse edge is provided, the stop having a bolt and a releasable latching device for the spring-loaded bolt in the direction of the bolt engagement, and the latching device being triggered when the bolt engagement and the stop contact. When the latching device is triggered, the spring-loaded bolt is pre-locked in the direction of the bolt engagement, which means that any free space between the stop and the bolt engagement is reduced.

For example, the bolt can dip into a second, otherwise unused bolt slot. This makes interaction possible even with large ones Relative displacements ensured and the bolt can absorb forces perpendicular to the sash or frame plane, which relieves the bolt element.

A structurally simple embodiment provides that the latching device consists of a cover part which is movably mounted with respect to a base part and which disengages a release spring of the bolt when it is displaced relative to the base part, as a result of which the bolt is not engaged. Only a few components are required for this.

The embodiment further provides that an S-shaped release spring is mounted on the base part, which engages with a first S-leg in a recess of the base part and the second leg is assigned to the edge of a recess of the cover part pretensioned. So that the locking element and the spring is made of components.

In order to be able to introduce the possibly occurring forces into the fitting, it is provided that the base plate for connection to the faceplate of the fitting has two mushroom-shaped pins, the keyhole openings are assigned to the faceplate and that a fixing screw with a shaft extends beyond the base plate into the faceplate protrudes. This allows the stop to be installed easily and can be fixed with just one screw.

In order to be able to transmit the forces acting on the bolt, the base plate receives the bolt in a U-shaped guide and the bolt is overlapped by the head of a cap screw mounted in the base plate.

In the Fig. 1 a stop 1 is shown by the fitting according to the invention for a window or a door. This is mounted in the known manner in the assembled state near a locking element 2 of the fitting. The locking element 2 is preferably a mushroom head pin, which engages through a faceplate 4 in an elongated hole for engagement with a striking plate which acts as a locking engagement 3. The faceplate 4 covers a rebate groove of the wing and guides a drive rod, not shown here, to which the locking element 2 is fastened. As a result of this arrangement, the locking element 2 can be displaced along the fold and, in its closed position, engages in a laterally open locking slot 5 of the locking engagement 3 which extends along the folding. The bolt engagement 3 is provided with a second bolt slot 6, which lies opposite the first bolt slot 5. The stop 1 is arranged on the side of the locking slot 6 at a short distance of a few millimeters from the locking engagement 3.

If an attempt is made to break in, the wing is moved against gravity in the direction of the upper horizontal frame spar (direction F) in order to move the locking element 2 out of the locking slot 5. The stop 1 comes to rest on the bolt engagement 3, as in the Fig. 2 evident. In this case, the cover part 7 moves relative to the base part 8 which is fixedly mounted on the faceplate 4.

According to the 4 to 7 the base part 8 forms a U-shaped guide for a bolt 9 which is acted upon by a spring 10 relative to the base part 8. The bolt 9 is after a release spring 11 in its closed position Fig. 4 held. For this purpose, the release spring 11, which is bent essentially in an S shape from a spring steel strip, engages with the angled S-leg 12 into a recess in the base part 8 and is fixed to the base part 8 with a rivet 13. The leg 14 located at the opposite end of the release spring 11 lies in a recess 15 of the base part 8. The web 16 connecting the legs 12, 14 is provided with a bead 17 which engages in a recess 18 of the bolt 9. The release spring 11 has a height which is larger than that of the bolt 9, so that the release spring 11 projects above it. The trigger spring 11 is biased with the web 16 in the direction of the bolt 9. The bead 17 is shaped as a hemispherical dome and the recess 18 is provided with rounded ends of the recess 18. The release spring 11 has sufficient movement space in the side facing away from the bolt, so that the bead 17 can emerge from the recess with a corresponding deflection. In the exemplary embodiment shown, the spring 10 is dimensioned such that the bead 17 is exposed to strong pressure. The arrangement and configuration of the bead 17 is chosen such that only a small deflection of the release spring 11 will result in the latch 9 being closed.

The leg 14 is supported on a web 19 which delimits a recess 20 in the cover part 7, as in the 7a and 7b is clearly recognizable. Due to the small distance between the leg 14 and the bead 17, the spring stiffness of the release spring 11 is sufficient not to be deformed to the extent that the bead 17 emerges from the recess 18. This takes place only when the cover part 7 is shifted slightly relative to the base part 8, so that the leg 14 slips off the web 19 and dips into the adjacent recess 20. This leads to a deflection of the release spring 11 and the bolt 9 closes. The arrangement is such that the bolt 9 plunges into the bolt slot 6, which has not been used until then.

In the case of a continued attempt to break in, this means that now pushing out the locking element 2 simultaneously results in a deeper penetration of the locking bar 9, so that the locking point is secured against prying out, as in Fig. 3 shown. The penetration of the locking element 2 and the locking bar 9 is advantageous for loading the locking engagement 3, since this is secured against twisting at a force directed perpendicular to the wing plane. The forces acting on one side as a result of such a load produce a torque which has an unfavorable effect on the fastening means of the locking engagement 3 which are arranged at a distance from the edge. A symmetrical locking of bolt 9 and bolt element 2 reduce the moments that arise or prevent them completely.

Deviating from the embodiment described above, see the Fig. 8 and 9 a modified trigger spring 11 before. As from the Fig. 8 can be seen, the base part 8 is substantially identical to the previous embodiment. Here, too, the cover part 7 and the base part intermesh with rectangular toothings 27, 28 for the changeable relative position assignment. By bringing together a suitable pair of teeth, the projection 29 can be adapted to assembly and manufacturing tolerances. The release spring 11 has a latching hook 30, to which a latching recess 31 is assigned on the bolt 9. An inclined web 32 is assigned to an opening 33 in the cover part 7, so that when the cover part 7 is displaced in the direction of the release spring 11, it is deflected and thus levered out the latching hook 30 from the latching recess 31 and thus for locking the latch 9 is coming. An adjacent recess 33 is effective together with the release spring 11 when the cover part 7 is adjusted. In both recesses 31, 33 protrusions 34, 35 protrude, which rest on the web 32. A tooth 36 adjoins the recess 31 with a bevel that is inclined in the opposite direction to the direction of connection, which allows the bolt 9 to be pushed back. This can be helpful if the latch was accidentally released during assembly.

In the Fig. 10 and 11 a third embodiment is shown. Analogous to the preceding examples, this has a cover part 7, a base part 8 and a latch 9. The bolt 9 is acted upon by the spring 10 and is held in its closed position by a release spring 11. Here, however, it is provided that the release spring 11 forms a sensing web 37 and that the release spring is arranged on the bolt opening 38. The trigger spring 11 forms an L, the shorter leg of which forms the sensing web, which runs parallel to the bolt opening 38 and the bolt guide and protrudes in front of the cover part 7 and the base part 8. An open-edged recess 39 in the long leg 40 serves for the passage of the bolt 9. The recess 39 is dimensioned so narrow that the bolt 9 is held by the narrow vertical edges when the release spring 11 is released. This is helped by the fact that the release spring 11 has a slightly arcuate shape in the relieved position.

In the exemplary embodiment shown, it is provided that the bolt engagement 3 has the first bolt slot 5 and an opposite second bolt slot 6. Deviatingly, it can also be provided that the locking engagement 3 is used exclusively for the engagement of the locking element 2 and a second locking engagement is applied on the same sash rebate surface exclusively for interaction with the stop 1. Although this arrangement requires the fastening of a further bolt engagement 3, the stresses on the bolts of the bolt interventions are reduced.

From the Figures 1 to 3 it can be seen that the base part 8 for connection to the faceplate 4 of the fitting has two mushroom-shaped pins 21 which are assigned to keyhole openings 22 of the faceplate 4 and that a fixing screw 23 with a shaft 24 projects beyond the base part 8 into the faceplate 4.

A further gain in strength is achieved in that the base part 8 receives the bolt 9 in a U-shaped guide 25 and the bolt 9 is overlapped by the head 26 of a fixing screw 23 mounted in the base part 8. Especially in the Figures 1 to 3 In the illustrated embodiment, the bolt additionally absorbs forces introduced perpendicular to the plane of the drawing with its greatest section modulus and the base part contributes to stiffening the faceplate 4. The selected attachment of the stop 1 on the faceplate 4 does not lead to a lasting weakening of the same by large bores.

The locking caused by the stop 1 can not be canceled via the connecting rod fitting. In the event of a massive attempted break-in, the wing is damaged in such a way that further use of the wing is impossible in practice anyway. If the attempted break-in is terminated with the bolt 9 triggered without further damage, if the stop 1 has been attached exclusively to the hinge side, the sash can be swung open after the drive rod fitting has been unlocked, so that the bolt 9 swings out of the bolt slot 6. This can only be achieved if the bolt has no undercut.

It is also conceivable with advantages for manipulation security of the triggered bolt 9 to secure the bolt 9 against being pushed back by means of a locking element. For this purpose, the bolt 9 is provided with corresponding positive locking means which only release the triggered bolt after the positive locking has been released. This can be a locking element which is spring-loaded on the base part 8 in the direction of the cover part 7 and is pushed between the latter and the fixing screw 23 when the bolt 9 is closed.

Fig. 12 shows an installation situation in which the stop 1 is fastened to a faceplate of the wing 41 (not visible here) and, together with the locking element 2 designed as a mushroom-headed pin, is assigned to a locking engagement 3 in the form of a striking plate. The locking engagement 3 is encompassed on both sides by the locking element 2 and the stop 1. When the wing 41 is lifted, the stop 1 abuts the latch engagement 3, with the above-described sequence of triggering the stop. At the same time, the stop 1 acts to reduce the clearance air and only permits a limited displacement of the wing 41 in the axial direction of the locking element 2. In fact, even after the latch 9 has been triggered, the stop 1 counteracts a relative displacement parallel to the direction of movement of the latch element 2. Here, the design of the cover part 7 is possible in such a way that the latch 9 is also triggered by striking the stop 1 on the frame 42.

Of course, fastening independent of a faceplate, next to the fitting, is also possible, provided that a corresponding bolt engagement is provided. This means that even a window that does not provide an espagnolette fitting at the relevant placement can be provided with a lock by arranging a bolt engagement 3 and a stop 1. This can be done by two stops 1, which are arranged with latches 9 to be pointed towards one another and maximized by a latch engagement 3 located between them. The bolts 9 are triggered one after the other when the wing 41 is displaced and ultimately prevent a parallel displacement of the wing 41 perpendicular to its plane.

It is easy to understand that the release of the latch 9 is an indicator of an attempted break-in. Accordingly, an electrical sensor can also forward a corresponding signal to an intrusion detection system. The sensor can be designed in a simple manner from a switch or also as a reed contact and an alarm loop when the bolt 9 is closed or opened. The switch can also detect a displacement of the bolt 9 as an optical sensor.

Deviating from this, however, it can be provided that the stop 1 is also arranged at other locations on the wing and interacts with other bolt interventions. Triggering the latch 9 then means, however, that the wing must be destroyed to open the window or the door, which is possible for a specialist company from the inside of the building. In this case, it can advantageously be provided that the bolt 9 engages behind an undercut of the bolt engagement 3 in the manner of the mushroom pin and can thus also absorb forces introduced perpendicular to the fold.

Finally, a configuration is also possible in which the bolt 9 is held by a predetermined breaking point of the cover part 7, which is broken when the cover part is displaced and thus releases the bolt 9.

In order to take back the effect of the stop 1 after triggering, it can be provided that according to the Figures 13 to 15 Shown embodiment of the stop 1 has an operating element 45. The control element 45 is a flat lever 46 which engages with an angular bend 47 in an opening 48 of the cover part 7. Here, the control element 45 with the bend 47 extends to the bolt 9 and is connected here to the bolt 9 by a rivet 49 which penetrates a bore 50 of the bend 47.

According to the Fig. 14 the lever 46 extends through a gap 51 between the wing 41 and the frame 42 to a frame end face 52 inside the room. As a result, after the triggering described above, the bolt 9 can be withdrawn on the part of the lever 46 projecting above the wing 41.

In the Fig. 16 it can be seen that the cover part 7 has a web 53 which holds the bolt 9 back. The latch 9 has crashed against the rear wall 54 in the retracted position. The cover part 7 protruding over the bolt 9 and the base part 8 is displaced with the web 53 against the bolt 9 until the web 53 shears, whereby the bolt 9 is released. The bolt 9 is then moved forward by the spring 10, which is supported on the bolt 55.
