Abstract

Window or door comprises a striking plate that when the window/door is closed is mounted on a window/door frame relative to a groove central axis of a leaf frame so that the central point of a second locking position lies relative to the z-axis on the groove central axis and the central point of a first locking position is arranged relative to the z-axis in an offset manner in the direction of the negative z-axis. The locking bolts (20) on a connecting rod fitting (18) are arranged so that the locking bolt central axis is arranged relative to the groove central axis in an offset manner in the direction of the negative z-axis. An independent claim is also included for a connecting rod drive for windows or doors.

Description

The invention relates to a drive rod fitting for windows or doors, which is installed in a receiving groove of a casement, with at least one locking pin, and a center along the receiving groove extending groove center axis and a Nutmittenebene extending through the Nutmittenachse and a perpendicular thereto and parallel to the casement plane Nutmittenhochachse is formed, wherein between a lateral surface of the locking bolt and the Nutmittenebene no interfaces are formed and that between the locking pin and the espagnolette fitting an offset means is arranged, wherein the locking pin shank, the offset means and the locking pin together have a contour.

In windows or doors, the casement with respect to the frame to achieve a gap ventilation function by a small gap of about 6 mm are parallel off, there is the problem especially with narrow-built profiles to arrange the drive means for the Parallelabstellung within the tightly measured rebate. This results especially in profiles with a low groove of 9 mm.

The DE 81 22 798 U1 discloses such an espagnolette fitting, wherein on a base plate a locking lug is arranged. The base plate is connected via a driving pin with the drive rod. At the bottom of the base plate, a web is arranged, which engages in a longitudinal slot of a faceplate. Thus, the locking lug is arranged in a very complicated to be manufactured unit.

From the DE 30 43 925 C2 is known a window in which executed with plane offset gate guides keep bolts ensure that, depending on the position of the locking pin within the slotted guides a parallel shutdown of the sash relative to the frame. The installation of such striking plates in a profile with a low groove, for example, 9 mm, would lead to space problems. This is due to the fact that in the closed state of the window, the groove center axis and thus the center of the locking pin must be located exactly in the end position for the closed window position of the slotted guide. Since the plane offset guide slot but now requires a certain amount of space for the plane offset in the direction of the sash, the strike plate would come here at low groove positions in contact with the rollover of the sash.

From the DE 27 05 802 C2 is an espagnolette fitting with a locking pin known which is eccentric with respect to its longitudinal axis and allows adjustment of the tightening pressure between sash and frame by appropriate rotation.

The invention has the object of providing a drive rod fitting for windows or doors of the type mentioned in such a way that a parallel Shelving is also possible for windows or doors with a low groove position.

To solve the problem is further provided according to the features of the preamble of claim 1 that the common contour is double L-shaped, wherein the second L is rotated relative to the first L once around its transverse axis and once about its vertical axis by 180 ° and the base legs of the first and second L congruent superimposed.

These features characterize that the amount of offset between the centerline of the groove location and the center axis of the latch bolt is so large that not only is there an eccentricity, but in fact an offset. The extent of the offset is adapted to the required offset dimension of the strike plate in the respective individual profile environment, so that it does not protrude beyond the Rahmenfalzkante out or can not collide with the wing flashover. Another advantage is that in addition to the task mentioned above, even with windows with low slot dimensions and no parallel shutdown of the casement with respect to the frame such an espagnolette fitting is used. This can be ensured in such windows with tight spaces by shifting the strike plates in less critical areas and appropriate adjustment of the locking pin secure locks. This double L-shaped design makes it easy to offset the locking bolt relative to the espagnolette fitting.

In a further development of the invention is provided according to the claims 2 and 4, that the offset means is formed of a bent tongue portion, and that the extent of Offset, which is formed by the offset means is between 4 and 10 mm, preferably 6 mm. Due to the bent tongue area a particularly flat connecting connection between the drive rod fitting on the one hand and the locking pin on the other hand is achieved.

In a further development of the invention is provided according to claim 3, that the offset means is arranged oriented relative to the espagnolette perpendicular to the window plane. The course of the locking pin shank and the offset means does not pass through the faceplate, but extends virtually laterally past it.

In a further development of the invention is provided according to claim 5, that the locking bolt has a rotatable about its vertical axis jacket sheath. With such a rolling piston, the frictional forces are reduced by rotation of the lateral surface about the locking pin vertical axis, since primarily rolling friction instead of sliding friction occurs.

In a further embodiment of the invention, it is provided according to claim 6, that the jacket envelope is arranged eccentrically relative to the vertical axis of the locking bolt and has locking means for certain angular positions. As a result, the tightening force of the sash is made adjustable relative to the frame.

Fig. 7 shows a window 10, consisting of a fixed with a wall stationary frame 12 and a movable relative to this wing frame 14. The wing frame is relative to the frame in a band-side vertical axis rotatable and tiltable about a horizontal axis, and in a parallel parked window state brought. The operation of the window is carried out with the operating handle 16, a in Fig. 1 recognizable espagnolette fitting 18 drives. The espagnolette fitting 18 in this case has locking pins 20 which can be brought into engagement with striking plates 22 and thus can lock the casement 14 relative to the frame 12.

In Fig. 1 In addition, it can be seen that the drive rod fitting 18 is a partial area of a corner drive 24. The representation of a corner 24 has only exemplary character, the invention can be used in all known hardware components, eg. B. transmission rails, be arranged. The Eckumlenkung consists of a faceplate 26 which is fixedly screwed to the casement 14, and one with respect to this longitudinally displaceable mounted drive rod 28. The drive rod 28 is connected to the locking pin 20th

How out Fig. 2 it can be seen, the locking pin can retract into a slotted guide 30 of the striking plate 22. He is then within the Fig. 5 shown slide guide 30 between the respective end positions 32, 34 movable. The entry and exit in and out of the slotted guide 30 via the inlet region 36. Off Fig. 5 It can also be seen that the slotted guide has a plane offset, since the two end positions 32, 34 have a different distance from the end face 38 of the striking plate 22. The position 32 corresponds to the closed position of the window, whereas the position 34 corresponds to the parallel parked position. The different distance dimension of the end positions 32, 34 to the end face 38 at the same time reflect the extent of the parallel shutdown.

FIG. 3 and FIG. 4 show this parallel adjustment clearly. Figure 3 represents the closed window position, whereas in Fig. 4 the parallel window position is visible. This is recognizable by the in Fig. 4 recognizable ventilation gap 40, 42. In Fig. 3 If this ventilation gap 44, 46 does not exist, the recognizable gap here corresponds exactly to the installation space required for the seal, which is not shown. The window in Fig. 3 is therefore closed and seals the interior of the room from the environment, whereas in Fig. 4 a night ventilation through the ventilation gap 40, 42 takes place.

In windows with a low groove position 48, so the distance between the Rahmenfalzkante 50 and the groove center axis 52 of the receiving groove 30 for the espagnolette fitting 18, there are often space problems when installing strike plates with a plane offset. Normal strike plates without plane offset have a largely straight course of the slide guide. Is now the slide guide with a plane shift, as in Fig. 5 , provided, so the strike plate forcibly requires a larger depth. In the normal case, the end position 32 for the closed window position is the reference point, from which the end position 34 extends in the direction of the interior of the room or in the direction of the sash, since the parallel adjustment also takes place in the direction of the interior of the room. For profiles with a particularly low groove position 48, for example, 9 mm, the strike plate would therefore abut against the wing flap 54 of the sash.

Precisely for this reason, the striking plate 22 is offset in the present invention, in the opposite direction of the wing flap 54. However, to still allow a reliable locking of the window, the locking pin must also be offset by the same amount in the same direction. Since a displacement of the entire drive rod fitting for reasons of the fixed groove 48 is not an option, in the present invention, all of the locking pin 20 was offset from the espagnolette fitting. This offset is in 3 and 4 implemented by the offset means 56. The locking pin 20 is offset from the locking pin shaft 58 connected to the drive rod 28.

In Fig. 6 a further embodiment of the invention is shown in which the locking pin 20 has a mushroom-like shape with a mushroom head 60. This mushroom head 60 increases the burglar resistance of the window, since the locking pin can better dig against the strike plate.

Fig. 8 shows an alternative embodiment of the closure device, in which the offset means 57 is arranged opposite the espagnolette fitting 18 oriented perpendicular to the window plane. With this variant even larger offset dimensions can be realized. For mounting the closure device in the casement, appropriately adapted cut-outs are to be provided in the region of the offset means.

Can be used, the closure device with the cranked locking bolt basically at all points in the window, where previously known closing points are provided with striking plates. Fig. 7 shows by means of several arrow representations such exemplary installation positions on the window.
