Description

Background of the Invention

1. a) Einen einenends an einem festen Rahmen des Fensters oder der Tür, insbesondere drehbar, anlenkbaren Ausstellarm;
2. b) einen Gleiter, mit dem der Ausstellarm anderenends relativ zu einem Flügel des Fensters oder der Tür verschiebbar anordenbar ist;
3. c) einen Riegel, der im verriegelten Zustand die Verschiebbarkeit des Gleiters begrenzt und im entriegelten Zustand nicht begrenzt.

The invention relates to a fitting for the unlockable rotary opening limitation of a window or a door, the fitting having the following features:

1. a) a raising arm which can be articulated at one end on a fixed frame of the window or door, in particular in a rotatable manner;
2. b) a slider with which the opening arm can be arranged at the other end so as to be displaceable relative to a sash of the window or the door;
3. c) a latch which limits the displacement of the slider in the locked state and does not limit it in the unlocked state.

The invention also relates to a window or a door with such a fitting.

It is known to use a rotary opening limiter on a window or a door that should only be able to be opened to a limited extent, for example to protect people in public buildings from falling out of the window or door. The rotary opening limitation can be canceled by unlocking a bolt, so that the wing can be opened further for instructed persons, in particular to be able to clean the wing more easily.

It should be noted that the prior art described herein is not necessarily published. It can therefore be internal state of the art.

In the case of the known rotary opening limitations, a slider is provided which is guided in a profile groove of the wing. At first glance, the use of the profile groove seems to enable a structurally simple design of the known windows or doors. In fact, however, it has been shown that, depending on the sash, numerous adjustments have to be made in order to install the rotary opening limiter.

A particular problem is the assembly of the bolt, which must protrude into the profile groove when locked, but must not protrude into the profile groove when unlocked. For this purpose, in the known windows or doors, depending on the design of the wing, a wide variety of mounting blocks for lining a bolt housing in which the bolt is arranged must be kept, tried out and assembled.

object of the invention

It is therefore the object of the invention to provide a fitting for the unlockable rotary opening limitation which can be easily mounted on different casements. It is also the object of the invention to provide a window or a door with such a fitting.

Description of the invention

This object is achieved according to the invention by a fitting according to patent claim 1 and a window or a door according to patent claim 10. The dependent patent claims reflect preferred developments.

The object according to the invention is thus achieved by a fitting mentioned at the outset, the fitting having the following feature:
d) a rail with a guide groove in which the slider is slidably guided, the rail being mountable on the wing.

According to the invention, it is thus possible to mount the glider largely independently of the wing. The slider is not slidably arranged in a profile groove of the wing, but in the guide groove of the rail of the fitting. As a result, there is no need to coordinate the bolt with the profile groove and wing dimensions, which significantly simplifies the assembly of the fitting according to the invention.

The rail can preferably be mounted on a profile groove of the wing. The rail can more preferably be pushed at least in sections into the profile groove. The guide groove is particularly preferably C-shaped in cross section.

In a further embodiment of the invention, the bolt has a resiliently mounted ramp. When locked, the ramp can be driven over in one direction, but not in the opposite direction. This is because the ramp can be displaced by the slider when it runs over its incline, but forms a stop for the slider in the opposite direction. As a result, the wing can be transferred from its wide open position to the position that can only be opened to a very limited extent, even when the bolt is in the locked state.

The fitting can have a bolt housing in which the bolt is arranged. The bolt housing can be arranged on the rail.

As an alternative or in addition to this, the bolt housing can have a bearing projection for arranging the bolt housing on the wing. The support projection can ensure that the bolt is arranged at the correct distance from the guide groove, since both the rail and the bolt housing can be supported on the same (reference) surface of the wing.

Two support projections are preferably provided on the bolt housing.

To actuate the bolt, the fitting can have a lock, it being possible for the lock to be arranged at least partially in the bolt housing.

The slider can have a mushroom-shaped end section that can be displaced in the guide groove. The fitting can be designed in a structurally particularly simple manner if the slider is designed completely in the shape of a mushroom head.

More preferably, the rail can have an end stop for the slider. The end stop can have a latching means for releasably holding the slider. As a result, the wing, for example to clean it, can be kept wide open and latched.

The latching means can be designed in the form of a constriction of the guide groove that can be resiliently displaced by the slider.

In order to be able to easily adapt the length of the rail to the dimensions of the wing, in particular to the width of the wing, the rail can be made in several parts.

The object according to the invention is also achieved by a window or a door with a fixed frame, a leaf that can be opened by rotation and a fitting described here. The fitting is mounted between the sash and the fixed frame. The rail can be mounted on the profile groove. The rail is preferably pushed at least in sections into the profile groove. The profile groove is particularly preferably C-shaped in cross section.

In a simplified structural design of the window or door, the bolt housing is held by the rail on the sash.

The wing can have a recess in which the bolt housing is accommodated.

Further advantages of the invention result from the description and the drawing. Likewise, the features mentioned above and those detailed below can be used according to the invention individually or collectively in any combination. The embodiments shown and described are not to be understood as an exhaustive list, but rather have an exemplary character for the description of the invention.

1 shows a window 10 with a fixed frame (window frame) 12 and a sash 14 arranged on the fixed frame 12 so that it can be opened at least by rotation. The window 10 in 1 is closed.

2 shows the window 10 partially open. Out of 2 it can be seen that between the fixed frame 12 and the wing 14 a fitting 16 is arranged to limit the rotary opening.

3 shows the window 10 with the sash 14 open as far as possible. The ability of the leaf 14 to be opened by rotation is limited by the fitting 16 . The fitting 16 has a deployment arm 18 . In the 3 The maximum opening width shown depends on the length of the raising arm 18 and the limiting angle of the raising arm 18 to the wing 14. The raising arm 18 is pivoted at one end to a bearing 20 on the fixed frame 12. At the other end, a slider 22 is arranged on the deployment arm 18 and is slidably guided in a guide groove 24 of a rail 26 .

The slider 22 can only be displaced to a limited extent in the guide groove 24 . In the present case, the rail 26 has an end stop 28 against which the slider 22 rests when the leaf 14 is in the maximum open state. This maximum open position of leaf 14 is in 3 shown. In this maximum open position, the wing 14 can be cleaned in a particularly easily accessible manner from both sides.

In normal operation, the present casement 14 should not be able to be opened by rotation so far, for example in order to prevent a person from falling out of the window 10 . The avoidance of a person falling out can be assured after the system test has been successfully passed. Furthermore, a sash that can only be opened with limited rotation can have a higher level of comfort in other ways. For example, collisions with pre-installed shading elements can be prevented.

The fitting 16 has a bolt 30 which serves as a stop for the slider 22 in the locked state in order to limit the ability of the wing 10 to be opened by rotation. 2 shows this state with clearly limited rotary opening. The bolt 30 can be transferred from the locked to the unlocked state or from the unlocked state to the locked state by a lock 32 : If the bolt 30 is unlocked, the slider 22 can be pushed to the end stop 28 and the leaf 14 can thus be opened to the maximum. When the bolt 30 is locked, the slider 22 can move from its position with the wing 14 closed (see FIG 1 ) coming, can only be moved up to bolt 30, so that the out 2 apparent severely restricted maximum turning opening width results.

4 shows another view of the wing 10 with the fitting 16 without the slider 22 (see 3 ) and the deployment arm 18 (see 3 ).

figure 5 shows a sectional view of window 10. Off figure 5 it can be seen that the fitting 16 has a bolt housing 34 , in particular a box-shaped one.

6 shows a part of the window 10 with the fitting 16 in an enlarged view. Out of 6 it can be seen that the wing 14 has a recess 36 in which the bolt housing 34 is accommodated. The bolt housing 34 rests on the wing 14 via support projections 38a , 38b . According to the invention, the mounting of the bolt housing 34 is particularly simple, since the position of the bolt 30 is not relative to the wing 14, but only relative to the rail 26—which is also subsequently mounted on the wing 14—must be aligned.

The bolt 30 can have a bevel 40 so that the slide 22 (see 3 ) can displace the bolt 30 against the restoring force of a spring 42 when shifted in the direction of an arrow 44 , but not when shifted in the opposite direction. In this way, the bolt 30 can be unlocked, the wing 14 opened wide and the bolt 30 immediately locked again, so that the wing 14 can be closed at any later point in time to such an extent that it is again severely restricted in terms of rotational opening.

7 shows fitting 16 with bolt housing 34. Off 7 it can be seen that the bolt housing 34 has an opening 46 . In the opening 46 is the lock 32 (see 3 ) insertable. The lock 32 is designed to lock (lock) or unlock (unlock) the bolt 30 .

8 shows another view of the fitting 16 from 7 .

9 shows rail 26. Off 9 it can be seen that the end stop 28 has a latching means 50 in the form of an elastically displaceable constriction 52 of the guide groove 24 . The glider 22 (see 3 ) can be detachably held at the end stop 28 so that maintenance or cleaning of the wing 14 (see 3 ) is easily possible.

the Figs. 10 , 11 , 12 and 13 show various sectional views of the sash 14 of the window 10 with mounted fitting 16 according to 4 . From the Figs. 10 -14 it can be seen that the rail 26 for attachment to the wing 14 is preferably at least partially inserted into a profile groove 54 of the wing 14. The profile groove 54 and/or the guide groove 24 is/are particularly preferably designed with a C-shaped cross section.

According to 11 correspondingly, at least one end section 56 of the slider 22 can be configured in the shape of a mushroom head for guidance in the guide groove 24 .

Taking all the figures of the drawing together, the invention relates in summary to a fitting 16 for a window 10 or a door. The fitting 16 has a latch 30 for limiting the rotary opening of a sash 14 of the window 10 or the door relative to a fixed frame 12 of the window 10 or the door. The bolt 30 limits the displacement of a slider 22 in the locked state. The slider 22 is guided in a guide groove 24 of a rail 26 . Preferably, both a bolt housing 34 having the bolt 30 and the rail 26 can be mounted on one side, in particular a profile groove 54, of the wing 14. The rail 26 is preferably in the profile groove 54 retractable. The invention further relates to a window 10 or a door with the fitting 16 mounted on the window 10 or the door.
