Description

DESCRIPTION

Revolving opening limiting arrangement for a window or door for limiting the rotary opening movement of a window sash or door

The invention relates to a rotary opening limiting arrangement for a window or a door for limiting the rotary opening movement of a window sash or a door according to the preamble of claim 1.

There is often a requirement to open a window or door sash just a little, to allow for ventilation. In this regard, it is to be avoided that the sash rotates fully open. On the other hand, you should make sure that the leaf does not snap shut. The sash must therefore be able to be fixed in a limited rotary opening position. Particularly when windows are installed in blocks of flats, the known swing opening limiters are not stable enough to avoid also in the case of high stresses due to wind, the sudden closing of a leaf, which is in a Limited rotary opening position.

From DE 102008049319 A1 a rotary opening limiting arrangement according to the order is known.

DE 9411278 U1 describes a roof window with a fixing device.

A device for fixing windows or door leaves equipped with a pivoting / tilting fitting is further known from DE 201 12136 U1.

It is therefore a task of the present invention to make available a rotary opening limiting arrangement, with which a leaf can be fixed particularly reliably in a limited rotary opening position, for example with an opening width of about 100 mm, so that the rotary opening position is also maintained in case of high stresses due to wind.

This task is solved according to the invention by means of a rotary opening limiting arrangement for a window or a door for limiting the rotary opening movement of a leaf or of a window or of a door with the characteristics according to claim one.

With a fixed frame side rotation limiting element is meant in this case an element, which is fixed at least indirectly to the fixed frame. This can be, for example, the case of the limitation of rotation of a bolt or a pin. It is also conceivable that the rotation limiting element is configured in the form of a mushroom head.

By means of the rotation limiting element guide, during the rotary opening of the leaf, the fixed frame side rotation limitation element can be guided by the rotation movement limiter, until it reaches a stop position, which is corresponds to a limited rotary opening position of the sash. At this point the swing limiting element can interact with the locking element, so that the swing limiting element is fixed on the swing motion limiter. In this way the sash is also fixed in the limited rotary opening position. The locking element prevents the swing limiting element from moving in the opposite direction along the swing limiting element guide.

In this regard, the locking element can be made, for example, of stainless steel, so that it is particularly stable and reliable locking is ensured even in high wind stress. The swing movement limiter can be made for example of aluminum.

Particular advantages result when the locking element is controlled by a drive bar. In this way, by means of a movement of the drive bar, which can be initiated by a drive manipulation zone, the locking element can be moved, in particular moving from a release position to a locked position, in which it locks the element turning limitation. In this way a locked rotary opening position can be adjusted by a user.

In a particularly simple way the blocking element can be brought from a release position to a blocking position and move back, since the blocking element is rotatably arranged within or in the rotational movement limiter. The locking element can be rotatable in particular about a vertical axis of rotation. When the locking member is rotated to a locking position, it can lock the swing limiting member with one section, so that it can no longer move linearly relative to the swing motion limiter.

The locking element can have a pin, which interacts with a guide on the side of the actuating bar. The pin may be disposed eccentrically in the locking element in this regard. It can also protrude downwards in the direction of the actuation bar of the locking element. The spike it may be hardened to be particularly stable in this way. The pin is preferably arranged on a side remote from the transmission mechanism of a drive rod fitting, from the locking element. As a result, pinching and blocking can be avoided.

The drive bar side guide may be configured as a slide. In this regard, the slide can have two sections essentially parallel, which are joined by a connecting section. When the pin of the locking element passes through the slide, a rotational movement can be introduced into the locking element due to this configuration, when the drive bar side guide moves in the perimeter direction of the leaf, in particular when it is inserted a movement in the drive bar. The drive bar side guide may in this respect be part of the drive bar or be a separate part, which is attached to the drive bar of a window or door fitting. The drive bar side guide may in this respect be made of stainless steel.

The locking element has an open housing in an unlocked position towards the guide of the rotation limitation element and which represents a stop for the rotation limitation element. In this way, when the leaf is rotatably opened, the rotation limitation element can move along the guide of the rotation limitation element, until it reaches the housing of the blocking element. The housing of the locking element represents a stop, so that the rotary opening movement is limited. The sash is now in a limited rotary open position. To lock the sash in this position, the locking element can now be moved, in particular rotated, to lock the swing limiting element in place. In this way the sash is also fixed in its limited swing open position.

In this sense it is advantageous when the locking element has a rear grip to subsequently grip the turning limitation element. This ensures that the swing limiting element does not automatically separate from the locking element. The rear grip may for example be configured as a recessed groove. In particular, when the swing limiting element is mushroom shaped, a recessed groove can hold the swing limiting element in place.

Other advantages result when the locking element has a height stop for fixing the position of the locking element in the rotary movement limiter. The height stop may in particular be configured as an annular groove. The locking element can be inserted from below into the swing movement limiter. The height stop prevents the locking element from leaving the swing motion limiter on the opposite side, and ensures that the locking element is disposed at the correct height on the swing motion limiter. Advantages are obtained when the rotation limiting element guide is configured as a slit and preferably extends in the perimeter direction of bending. The guide of the rotation limitation element can also be configured as a recessed groove and thus partially overcome the rotation limitation element, in particular when it is configured as a mushroom head, so that the rotation limitation element it is securely clamped on the slew limiting element guide and cannot particularly leave it upward. As a result, the operational safety of the rotary opening limiting arrangement is increased.

There may further be provided a swing limiting arm, in which the swing limiting element is arranged and which is pivotally mounted on a fixed frame. The swing limiting arm may for example be a component of a so-called second holding arm. By means of the swing limiting arm it can be determined how far the leaf can be opened for a limited swing opening position. The swing limiting element may be arranged in particular at the free end of the swing limiting arm. To ensure that a leaf can also be rotatably opened fully, it is advantageous when a leaf-side coupling element is provided, which can be mounted in particular on a drive bar, which couples the element for a rotational opening limiting function. swing-side limitation and releases the swing-limiting element for full rotary opening. In this way it can be maintained for a rotary opening limiting function by the coupling element, the rotational limiting element on the sash. In this case the sash can only be rotatably opened to a limited extent. In case of eg disengaging the swing limiting element from the sash, as soon as the coupling element assumes a predetermined position, then the sash can rotatably open fully, since the slewing opening movement is no longer limited by the rotary opening limiting arrangement.

The coupling element can have a locking section and a release section. With the locking section the swing limiting element can be kept on the sash. In case the coupling element is nevertheless moved, in particular moving in the perimeter leaf direction, then a release section can release the rotation limiting element, so that a decoupling occurs.

The rotational movement limiter can have a housing for the coupling element. The coupling element can be connected to the actuation bar and thus be movable relative to the rotary movement limiter. When the coupling element can enter the movement limiter of rotation, the coupling element does not prevent the actuation bar from being able to move for a blocking position and thus the blocking element can be rotated.

Within the scope of the invention there is furthermore a window or a door with a rotary opening limiting arrangement according to the invention. Such a window or door face particularly high wind loads.

The stability with regard to wind stresses that make their appearance can be further increased because both above, as well as below, in the window or door, a rotary opening limiting arrangement is provided.

Other characteristics and advantages of the invention result from the following detailed description of exemplary embodiments of the invention, from the drawing figures, which shows essential details of the invention, as well as from the claims. The features shown there are not necessarily to be understood to scale and are represented in such a way that the features according to the invention can be made clearly visible. The different characteristics may be carried out individually by themselves or in any combination in variants of the invention.

Figure 1 shows a window 1 with a fixed frame 2 and a leaf 3 in a top view, the leaf 3 being somewhat rotatably open. The opening position of the leaf 3 is limited by a rotary opening limiting arrangement 4. The rotating opening limiting arrangement 4 comprises a rotary movement limiter 5, which is mounted on the leaf 3 through a bar 6. The movement limiter 5 comprises a guide for the rotation limitation element 7, which is configured as a slit and by which a rotation limitation element 8 is guided, which is arranged in a free end of a swing limitation arm 9. When the leaf 3 is opened, the swing limitation element 8 in the guide 7 moves from right to left, the swing limitation arm 9 being pivoted in relation to the frame 2 fixed to the position shown. The swing limiting arm 9 is therefore pivotally or rotatably arranged in the fixed frame 2. In the position shown, the rotation limiting element 8 comes into contact with a stop that will be shown in greater detail later, so that the leaf 3 cannot continue to open. A drive manipulation zone 10, which is shown here by way of example only, is in one position, which allows a rotary opening of the sash to a limited rotational opening position.

Fig. 2 corresponds essentially to Fig. 1. In particular the sheet 3 is shown in a limited rotary opening position. However, the drive handling area 10 has been brought here to a closed position. This means that the drive bar 6 has moved. This has resulted in a locking element 12 being rotated in the rotational movement limiter 5, so that it now locks the rotational limiting element 8, so that it can no longer move to the right. This means that the rotation limiting element 8 is fixed with respect to the rotation movement limiter 5 in the position shown. Sheet 3 can no longer be closed in this way. Sheet 3 in particular cannot be closed due to a gust of wind. In order to re-close the leaf 3, the drive handling area 10 must be rotated from the position shown in Fig. 2 back to the position shown in Fig. 1, so that the locking element 12 releases the swing limiting element 8, so that the swing limiting element 8 can move clockwise along the rotation limiting element guide 7, to close the leaf 3.

The movement of the drive bar leads to a displacement of a guide 15 on the drive bar side, due to which the locking element 12 is rotated. This will be explained in detail below.

Fig. 3 shows window 1, sheet 3 being closed. The drive manipulation area 10 has been brought to a third switching position, due to which a coupling element 16, which is fixed to the drive bar 6, has been moved to the right, so that a section of release 17 has been matched with the swing limiting element 8. This means that the swing limiting element 8, and thus the swing limiting arm 9, has been disengaged from the sash 3. When it is brought to Now an opening movement of the leaf 3 is carried out, then the rotation limiting arm 9 is not pivoted, and the leaf 3 can be rotatably opened completely. In particular the coupling element 16 is moved by the movement of the drive manipulation zone 10 to the position shown in Fig. 3. The release section 17, which in Fig. 1 is located in the rotational movement limiter 5, has been shifted to the right in this regard, so that the rotary limiting element 8 can move in the area of the releasing section 17 between the right end of the rotational movement limiter 5 and a locking section 18 of the coupling element 16 and in this way decoupling from the sheet 3.

Fig. 4 shows a top perspective view of the swing movement limiter 5. The swing movement limiter 5 can be fixed, for example, by means of head screws 20, 21 on the sheet 3. At the end of the guide Rotation limiting element 7 is provided with the locking element 12, which can be rotated relative to the rotation movement limiter 5. In the position shown, the guide of the rotation limitation element 7 opens into a housing 23, which is open in the direction of the rotation limiting element guide 7. In Fig. 4 the locking element 12 has an unlocked or released position. The end of the housing 23 forms a stop 24 for the rotation limiting element 8. In case of turning the blocking element 12 controlled by the drive bar, then the housing 23 no longer opens into the guide of the limiting element of rotation 7, so that the rotation limitation element 8 cannot move towards the guide of the rotation limitation element 7.

Fig. 5 shows the swing movement limiter 5 in a perspective view from below. Here it can be seen that the rotation limiting element guide 7 is configured as a recessed groove. In addition, it can be seen that the rotation movement limiter 5 has a housing 25 for the coupling element 16, so that it can move to the area of the rotation movement limiter 5. It can also be seen a housing 26 for the locking element 12, the locking element 12 preferably being inserted from below, that is, from the side shown in Fig. 5, in the mounting in the housing 26.

Fig. 6 shows the locking element 12 in a perspective view. The locking element 12 is essentially cylindrical in shape. It shows the housing 23 with stop 24. It can be seen here that the housing 23 is also configured as a recessed groove. At the lower end, the locking element 12 has a pin 30, which interacts with a drive bar side guide, in particular of the slide 15. The pin 30 is eccentrically arranged in the locking element 12. The Locking element 12 furthermore has an annular groove 31, through which the locking element 12 is held in the rotary movement limiter 5 in the correct position, in particular height. In this way it can be ensured that the locking element 12, as shown in Fig. 4, is flush with the upper side of the swing motion limiter 5.

Fig. 7 shows a positioning piece 40, which can be fixed to the actuating bar 6. The positioning piece 40 has a guide configured as a slide 15, for the pin 30. In case of moving the actuating bar 6 and in this way the slide 15 in relation to the pin 30, the pin accesses from the straight slide section 15.1 through the slide section 15.2 to the straight slide section 15.3, which is arranged essentially parallel with respect to the section sliding 15.1. Because the pin 30 accesses from the slide section 15.1 to the slide section 15.3, the locking element 12 is rotated and enters from a release position to a locking position, in which it fixes the rotation limiting element 8 in position in the rotational movement limiter 5. In the case of an opposite drive bar movement, the locking element 12 is rotated back, so that a release position is adopted. The movement of the locking element 12 is thus completely controlled by means of a drive bar. In particular, no spring-requested return position of the locking element 12 is provided, since this could lead to malfunctions.

Fig. 8 shows the swing limitation arm 9 in a bottom view. The rotation limiting arm 9 is fixed through a frame fixing part 50 to the fixed frame 2 and can be pivoted relative to the frame fixing part 50 and thus relative to the fixed frame 2. The rotation limiting element 8 is configured as a mushroom head pin. The widening of the swing limiting element 8 is in particular wider or has a diameter larger than the free width of the swing limiting element guide 7 and also that the free width of the housing 23, so that the rotation limiting element 8 cannot escape upwards, when the rotation movement limiter 5 is mounted above in the window 1, or downwards, when the movement limiter Turn 5 is mounted down the window.

Fig. 9 shows the coupling element 16 with its releasing section 17 and its blocking section 18. The coupling element 16 has two opposite walls 41,42 by its length, the walls 41, 42 representing a guide for the element Limitation of rotation 8. Furthermore, the wall 41 blocks the limitation of rotation 8, when the leaf 3 is not to rotate fully open. In the releasing section 17, however, a wall opposite to the wall 42 is missing, so that the rotation limiting element 8 can be decoupled and thus rotatably open the sheet completely. Wall 41 is shorter than wall 42.
