"Closure with to be brought in three different positions Bar for tilt and turn windows ".

The innovation relates to a rod lock for sashes of windows, doors or the like that can be pivoted around a vertical or horizontal axis, so-called tilt and turn windows, in which the closure with one in three different, the closed, turn and tilt position the sash has to be adjusted accordingly.

In the known fittings of the above type, so in which the wing depending on the setting of the lock either locked in the fixed frame or rotated or tilted can easily result in operating errors can be made if, for example, the shutter is subsequently set to "rotate" or when the sash is tilted Wing is switched to "tilt". In both cases, unwanted unlocking occurs, leading to one more or less dangerous falling out of the wing

the intended situation in each case. This will also the fittings are affected.

The innovation is now based on the task of one To create closure in which the above-mentioned operating errors by inadvertently operating the lock incorrectly in the endangered setting positions of the sash Security will be prevented. According to the innovation, this is achieved by a locking lock that interacts with the lock, which preferably occurs when turning and / or tilting or in the "turning" and / or "tilting" position of the wing of the lock in one of the damaging positions. This means that the The lock is only activated in a certain wing position, preferably when the wing is in contact with the fixed frame while it is blocked in any other position, in particular in the "turning" or "tilting" position.

The operation of a window equipped with such a locking device is as follows in front of youi Assume that the wing is fixed Frame on. In this position the locking device is ineffective. The lock can be in any position, that is, from its "closed" position into the "turning" or "tilting" position. Will the shutter on tilting placed, so the wing can around its horizontal axis

be tilted. As soon as the sash lifts off the frame, the locking device is activated. The shutter is locked. It is in this position of the wing no longer possible to switch the lock to "turn", thereby avoiding unwanted unlocking and damage to the fittings caused by them will. If the wing is to be transferred from its "tilt" position to the "turning" position, the wing must first be placed back on the fixed frame. Only then can the shutter be set to "turn" and the wing rotated around the vertical axis. The way the sash lifted itself off the fixed frame the shutter again blocks, i.e. it cannot be switched to "toggle". For this it is again necessary to first bring the sash back to the fixed frame.

In general, it is only harmful if the shutter is in the "turn" position when the sash is tilted and is switched to the "tilt" position with the sash rotated. In contrast, it is mostly harmless if when the wing is rotated or tilted, the shutter is brought into the "closed" position. Such a way of moving can sometimes even be desirable, for example in order to have different sizes when the sash is tilted

Gap widths by turning the lock back into the "closed" -S to lock the sash or to open the sash in various positions by turning it back when the sash is turned to hold the lock in its "closed" position » For these purposes, it is therefore advantageous to use the blök-, kieren the locking mechanism only to the extent that when the sash is tilted, just move the lock to "turn" and when the sash is turned, switch over the Closure on "tipping" is prevented.

The design and arrangement of the locking device can be made and directed in a wide variety of ways individually according to the above-mentioned possible applications. The locking device advantageously consists of a spring-action embedded in the sash frame standing pawl, which is with its locking lug in the rotating and tilting position of the wing in the locking linkage locking notches provided at corresponding distances from one another inserts, however, in the closed position of the sash by resting on the fixed frame from the Notches is lifted. Such a trained lock is an embodiment of the innovation in the Drawings illustrated. It shows:

3 with the wing in the "turning" position.

The turn-tilt window shown in the figures in a sectional partial view consists essentially of the wing attached in the usual way to the fixed frame 1 via fittings not shown here In the latter, the setting positions are in three different positions, corresponding to the closed, rotated and tilted positions of the sash To be brought closure housed, of which in the case shown only the correspondingly height-adjustable Closing rod 3 is shown. The lower end 4 of this rod acts in the closed and tilted position of the lock with the locking block 5 provided on the fixed frame, with which it is the front one in the tilted position Forms tilt joint.

According to the innovation is now in the sash 2 a The locking pawl 6 is provided which forms the locking lock and is under the action of the leaf spring 7. The pawl 6 is provided with a locking lug 8, which in the "turn" and "tilt" position of the wing in on the locking rod 3 in Locking notches provided at the appropriate intervals 9

"or 10 engages. In the closed position of the sash (FIG. 2), the pawl 6 rests with its bow-like part 11 against the fixed frame 1, whereby the pawl pivots around the hinge pin 12 and with its nose 8 out of the notches 9 E.g. 10 is excavated.

Haoh a further proposal according to the hiring, the locking lock can also be housed in the casement Gravity pendulum be designed »with a crouch provided on it in the tilted position of the wing in a locking catch provided on the locking rod engages, on the other hand, in the closed and rotated position of the wing, it is out of engagement with the detent. The operation of the In this case, the locking mechanism does not take place by positioning the sash against the frame, but exclusively under the action of gravity. In addition, the lock is only blocked in the tilted position, which is shown in is desirable in many cases. Another advantage of this type of training is that it is inside The pendulum to be accommodated in the sash is inaccessible to any external influence '. It thus forms Also an excellent anti-theft device, since the lock in the tilted position of the sash is in no way, i.e. neither can be moved from the outside or from the inside of the window.

Training and installation of the locking device according to the innovation are not based on those described above Embodiments "limited. It can be manifold Modified and installed in various ways. What is essential for the fire is the suggestion, in the case of rod locks, especially those for so-called tilt and turn windows, one in certain positions de3 sash that takes effect automatically, the switchover of the lock in the respective damaging setting positions to prevent locking.
