Description

The invention relates to a Drehöffnungsbegrenzungsanordnung for a window or a door for limiting the rotational opening movement of a wing of a window or a door.

Often there is the requirement to open a wing of a window or a door only a little way to realize a ventilation can. It should be prevented that the wing completely opened. On the other hand, it should be ensured that the wing does not strike. The wing should therefore be able to be set in a limited rotational opening position. In particular, when windows are installed in high-rise buildings, known Drehöffnungsbegrenzer are not stable enough to prevent the slamming of a wing, which is located in a limited rotational opening position, even at high wind loads.

Object of the present invention is therefore to provide a Drehöffnungsbegrenzeanordnung, with a wing in a limited rotational opening position, for example, with an opening width of about 100 mm, can be reliably set so that the rotational opening position is maintained even at high wind loads.

This object is achieved according to the invention by a Drehöffnungsbegrenzungsanordnung for a window or a door for limiting the rotational opening movement of a wing of a window or door with a mountable on a wing of the door or window Drehbewegungsbegrenzer, a Drehbegrenzungselementführung for a fixed frame side rotation limiting element and a locking element for fixing having the rotation limiting element in a limited rotational opening position.

Under a fixed frame-side rotation limiting element is understood here an element which is at least indirectly attached to the fixed frame. For example, the rotation limiting element may be a bolt or a pin. It is also conceivable that the rotation limiting element is formed mushroom-head-shaped.

By Drehbegrenzungselementführung the fixed frame-side rotation limiting element can be performed on Drehbewegungsbegrenzer when turning open the wing until it enters a stop position corresponding to a limited rotational opening position of the wing. At this point, the rotation limiting element can interact with the blocking element, so that the rotation limiting element is fixed on the rotary movement limiter. Thus, the wing is set in the limited rotational opening position. The blocking element prevents the rotation limiting element from moving in the opposite direction along the rotation limiting element guide.

In this case, the blocking element may for example be made of stainless steel, so that it is designed to be particularly stable and reliable locking is ensured even at high wind loads. The Drehbewegungsbegrenzer may be formed, for example, of aluminum.

Particular advantages arise when the blocking element is driven by a drive rod. Thus, by a movement of the drive rod, which can be initiated by an actuating handle, the blocking element to be moved, in particular to be moved from a release position to a blocking position in which it locks the rotation limiting element. Thus, controlled by a user, a locked rotational opening position can be adjusted.

In a particularly simple manner, the blocking element can be moved from a release position into a blocking position and back when the blocking element is rotatable, in particular rotatable about a vertical axis of rotation, in or on the rotational movement limiter. If the blocking element is rotated into a blocking position, it can block the rotation limiting element with a portion, so that it can no longer be moved linearly relative to the rotational movement limiter.

The locking element may comprise a pin which cooperates with a drive rod side guide. The pin can be arranged eccentrically on the blocking element. He can also protrude downwards in the direction of drive rod from the blocking element. The pin may be hardened to be formed particularly stable. Preferably, the pin is arranged on a side facing away from the transmission of a drive rod fitting side of the locking element. This can prevent jamming and blockage.

The drive rod side guide can be designed as a backdrop. In this case, the backdrop may have two substantially parallel sections, which are connected by a connecting portion. When the pin of the locking element passes through the gate, due to this configuration, a rotational movement in the locking element can be initiated when the drive rod side guide is moved in the wing circumferential direction, in particular when a movement in the Driving rod is initiated. The drive rod side guide can be part of the drive rod or be a separate part which is attached to the drive rod of a fitting of the window or the door. The drive rod-side guide can be made of stainless steel.

According to one embodiment of the invention can be provided that the blocking element has a in an unlocked position for Drehbegrenzungselementführung open and a stop for the rotation limiting element performing recording. Thus, upon rotation of the wing, the rotation limiting element can be moved along the rotation limiting element guide until it reaches the receptacle of the blocking element. The inclusion of the locking element is a stop, so that the rotation opening movement is limited. The wing is now in a limited rotational opening position. In order to fix the wing in this position, the locking element can now be displaced, in particular rotated, in order to fix the rotation limiting element in its position. Thus, the wing is set in its limited rotational opening position.

In this context, it is advantageous if the blocking element has a rear grip for engaging behind the rotation limiting element. This ensures that the rotation limiting element does not automatically release from the blocking element. For example, the rear grip may be formed as an undercut groove. In particular, when the rotation limiting element is formed mushroom-shaped, an undercut groove can hold the rotation limiting element in position.

Further advantages result if the blocking element has a height stop for fixing the position of the blocking element in the rotary movement limiter. In particular, the height stop may be formed as an annular groove. The locking element can be inserted from below into the Drehbewegungsbegrenzer. The height stop prevents the locking element, the rotary motion limiter on the leaves the opposite side, and ensures that the blocking element is arranged at the correct height on the rotary movement limiter.

Benefits arise when the Drehbegrenzungselementführung is slit-like and preferably extends in Falzumfangsrichtung. The Drehbegrenzungselementführung may be formed as an undercut groove and thus the Drehbegrenzungselement, especially if this is mushroom-shaped, partially overlap, so that the rotation limiting element is securely held in the Drehbegrenzungselementführung and this particular can not leave upwards. As a result, the reliability of the Drehöffnungsbegrenzungsanordnung is increased.

Furthermore, a Drehbegrenzerarm be provided on which the rotation limiting element is arranged and which is pivotally mounted on a fixed frame. The Drehbegrenzerarm may for example be part of a so-called second pair of scissors. By Drehbegrenzerarm can be determined how far the wing can be opened for a limited rotational opening position. The rotation limiting element may in particular be arranged at the free end of the Drehbegrenzerarms.

In order to ensure that a leaf can also be completely opened in rotation, it is advantageous if a wing-side coupling element, which can be mounted in particular on a drive rod, is provided which, for a rotational opening limiting function, couples the rotation limiting element on the wing side and releases the rotation limiting element for a complete rotational opening. Thus, for a Drehöffnungsbegrenzungsfunktion by the coupling element, the rotation limiting element can be held on the wing. In this case, the wing can only be opened to a limited extent. If, however, the rotation limiting element is decoupled from the wing by the coupling element assumes a predetermined position, so the wing can be completely opened in rotation, since the rotational opening movement is no longer limited by the Drehöffnungsbegrenzungsanordnung.

The coupling element may have a locking portion and a release portion. With the locking section, the rotation limiting element can be held on the wing. If, however, the coupling element is displaced, in particular displaced in the circumferential direction of the wing, then a release section can release the rotation limiting element, so that a decoupling takes place.

The rotational movement limiter may have a receptacle for the coupling element. The coupling element may be connected to the drive rod and thus be movable relative to the rotary motion limiter. If the coupling element can enter into the rotational movement limiter, the coupling element does not prevent that the drive rod can be displaced for a blocking position and thus the blocking element can be rotated.

The scope of the invention also includes a window or a door having a rotary opening limiting arrangement according to the invention. Such a window or door withstands particularly high wind loads.

The stability with regard to occurring wind loads can be further increased by the fact that both top and bottom of the fixed or on the door a Drehöffnungsbegrenzungsanordnung is provided.

The Fig. 1 shows a window 1 with a fixed frame 2 and a wing 3 in a view from above, wherein the wing 3 is a bit wide open. The open position of the wing 3 is limited by a Drehöffnungsbegrenzungsanordnung 4. The rotary opening limiting arrangement 4 comprises a rotary movement limiter 5, which is mounted on the wing 3 above a drive rod 6. The Drehbewegungsbegrenzer 5 comprises a Drehbegrenzungselementführung 7, which is designed like a slot and in which a rotation limiting element 8, the free end of a Drehbegrenzerarms 9 is arranged, is guided. When opening the wing 3, the rotation limiting element 8 is moved in the guide 7 from right to left, wherein the Drehbegrenzeram 9 pivots relative to the fixed frame 2 in the position shown. The Drehbegrenzeram 9 is therefore arranged pivotably or rotatably on the fixed frame 2. In the position shown, the rotation limiting element 8 strikes against a stop, which will be shown later in detail, so that the wing 3 can not be opened further. An actuating handle 10, which is shown here only symbolically, is in a position which allows a rotational opening of the wing to a limited rotational opening position.

The Fig. 2 essentially corresponds to the Fig. 1 , In particular, the wing 3 is shown in a limited rotational opening position. However, here the actuating handle 10 has been brought into a closed position. This means that the drive rod 6 has been moved. This had the consequence that a blocking element 12 was rotated in Drehbewegungsbegrenzer 5 so that it now locks the rotation limiting element 8, so that it can not be moved to the right. This means that the rotation limiting element 8 is fixed with respect to the rotational movement limiter 5 in the position shown. The wing 3 can not be closed accordingly. In particular, the wing 3 can not be closed due to a gust of wind. In order to close the wing 3 again, the actuating handle 10 must be made of in the Fig. 2 shown position again in the in the Fig. 1 rotated position shown so that the locking element 12 releases the rotation limiting element 8, so that the rotation limiting element 8 can be moved to the right along the Drehbegrenzungselementführung 7 to close the wing 3.

The drive rod movement leads to a displacement of a drive rod-side guide 15, whereby the blocking element 12 is rotated. This will be explained in detail below.

The Fig. 3 shows the window 1, wherein the wing 3 is closed. The actuating handle 10 has been brought into a third switching position, whereby a coupling element 16 which is attached to the drive rod 6, has been displaced to the right, so that a release portion 17 has come into coincidence with the rotation limiting element 8. This means that the rotation limiting element 8 and thus the Drehbegrenzeram 9 was decoupled from the wing 3. Now, if an opening movement of the wing 3 is performed, the Drehbegrenzeram 9 is not pivoted and the wing 3 can be fully opened in rotation. In particular, by the movement of the actuating handle 10 in the in Fig. 3 shown position the coupling element 16 moves to the right. The release portion 17, located in the Fig. 1 is located in Drehbewegungsbegrenzer 5, was displaced to the right, so that the rotation limiting element 8 can be moved in the region of the release portion 17 between the right end of the Drehbewegungsbegrenzers 5 and a locking portion 18 of the coupling element 16 and thus decoupled from the wing 3.

The Fig. 4 shows a perspective top view of the Drehbewegungsbegrenzer 5. The Drehbewegungsbegrenzer 5 can be set, for example via grub screws 20, 21 on the wing 3. At the end of the Drehbegrenzungselementführung 7, the blocking element 12 is arranged, which is rotatable relative to the Drehbewegungsbegrenzer 5. In the position shown, the rotation limiting element guide 7 opens into a receptacle 23 which is open towards the rotation limiting element guide 7. In the Fig. 4 the blocking element 12 has an unlocking position or release position. If the blocking element 12 is rotated by a drive rod, the receptacle 23 no longer opens into the rotation limiting element guide 7, so that the rotation limiting element 8 can not be displaced into the rotation limiting element guide 7.

The Figure 5 shows the Drehbewegungsbegrenzer 5 in a perspective view from below. Here it can be seen that the rotation limiting element guide 7 as undercut groove is formed. In addition, it can be seen that the rotational movement limiter 5 has a receptacle 25 for the coupling element 16, so that it can be displaced into the region of the rotational movement limiter 5. Furthermore, a receptacle 26 for the blocking element 12 can be seen, wherein the blocking element 12 preferably from below, ie from the in the Fig. 5 shown side, is inserted in the mounting 26 in the mounting.

The Fig. 6 shows the blocking element 12 in a perspective view. The blocking element 12 is substantially cylindrical. It shows the receptacle 23 with stop 24. Here it can be seen that the receptacle 23 is also formed as an undercut groove. At the lower end, the locking element 12 has a pin 30 which cooperates with a drive rod side guide, in particular the link 15. The pin 30 is arranged eccentrically on the blocking element 12. Furthermore, the blocking element 12 has an annular groove 31, by which the blocking element 12 is held in the rotary movement limiter 5 in the correct position, in particular height. Thus, it can be ensured that the blocking element 12, as shown in the Fig. 4 is shown, with the top of the rotary movement limiter 5 is flush.

The Fig. 7 shows an attachment 40, which is fastened to the drive rod 6. The attachment 40 has a trained as a gate 15 guide for the pin 30. If the drive rod 6 and thus the gate 15 is displaced relative to the pin 30, the pin passes from the straight gate section 15.1 via the gate section 15.2 in the straight gate section 15.3, which is arranged substantially parallel to the gate section 15.1. Due to the fact that the pin 30 comes from the gate section 15.1 to the gate section 15.3, the blocking element 12 is rotated and passes from a release position into a blocking position in which it defines the rotation limiting element 8 in its position on the rotary movement limiter 5. In an opposite espagnolette movement, the locking element 12 is rotated back, so that a release position is taken. The movement of the blocking element 12 takes place thus completely driven by a drive rod. In particular, no spring-loaded provision of the blocking element 12 is provided, since this could lead to malfunction.

The Fig. 8 shows the Drehbegrenzeram 9 in a view from below. The Drehbegrenzeram 9 is fixed via a frame attachment member 50 on the fixed frame 2 and is pivotable relative to the frame attachment member 50 and thus to the fixed frame 2. The rotation limiting element 8 is designed as a mushroom-shaped pin. The widening of the rotation limiting element 8 is, in particular, wider or has a larger diameter than the clear width of the rotation limiting element guide 7 and also the clear width of the receptacle 23, so that the rotation limiting element 8 is not mounted upward when the rotational movement limiter 5 is mounted on top of the window 1, or down, when the Drehbewegungsbegrenzer 5 is mounted at the bottom of the window, can escape.

The Fig. 9 shows the coupling element 16 with its release portion 17 and its locking portion 18. The coupling element 16 has over its length two opposite walls 41, 42, wherein the walls 41, 42 constitute a guide for the rotation limiting element 8. In addition, the wall 41 locks the rotation limiting element 8 when the wing 3 is not to be completely opened in rotation. In the release section 17, however, a wall 42 opposite the wall is missing, so that the rotation limiting element 8 can be decoupled and thus the wing can be completely opened in rotation. The wall 41 is shorter than the wall 42.
