Description

The invention relates to a window or a door according to the preamble of claim 1.

To limit or prevent the dynamic and, in individual cases, self-destructive movement of window sashes, e.g. B. by wind, it is desirable that this wing is locked after a slamming without moving the locking rod fitting on the frame. A further movement of the wing from this locked position should only be initiated by the user. Latch bar fittings are eg in the DE 10 2013 100 308 A1 .

The object of the invention is to solve this problem and to create a correspondingly designed window or a correspondingly designed door.

The invention solves this problem by the subject matter of independent claim 1. Advantageous embodiments can be found in the dependent claims.

According to claim 1, a window or a door is created which has a window frame made of several window frame profiles and a sash which is arranged thereon and can be rotated about a horizontal or vertical axis of rotation and is composed of several sash frame profiles, wherein the sash frame also has a locking bar fitting with one or several locking bars, with which first locking elements can be moved into a locking position for engaging behind corresponding locking elements on the window frame and back into an open position, wherein a latch catch device is also provided, with which the sash can also be opened when the locking bar arrangement is in the open position and the sash is closed after opening, can be latched in a latched position on the frame, the release of the latch catch device from the latched position by means of the locking bar fitting taking place in such a way that it is moved from an open position into a locking position and then back into the open position.

This has several advantages. By automatically activating the latch catch device, the sash can be easily locked or held in place on the frame when it is slammed/closed. In this way, the sash is locked on the window frame by a latch catch device after it has been slammed shut (and also after it has slowly closed), without the locking rod fitting having been moved into its locking position. It is particularly advantageous that the latch catch device can be easily deactivated - e.g. by moving the handle into the locking position and then back into the open position. Surprisingly, operating the window does not require any additional manual intervention, despite the latch catch device, except, as a rule, in this situation after the sash has slammed shut, e.g. due to wind, the locking rod fitting has to be moved into the locking position anyway to lock the sash, and then - immediately or later - if the sash is to be opened, back to the open position.

It is preferred - since it is structurally simple - that the latch catch device has a locking pin assembly arranged on the at least one movable locking rod(s) of the casement frame with a locking pin that can be moved by a drive means and is preferably spring-loaded, and a latch assembly arranged on the window frame with a base and with a latching hook section with a latching lug behind which the spring-loaded locking pin is latched in the latched position. Furthermore, according to a particularly preferred variant, provision can first be made for the latching hook section to be movably arranged on the base and for the base to be fixed immovably on one of the frame profiles of the frame, with the latching hook section on the base moving between a release position and a latching position. and is movable. The drive means acting on the latch pin may be a spring. The spring that acts on the locking pin can be designed in a wide variety of ways, such as a helical spring or disk spring or an elastomer spring or the like. The drive means, which acts on the locking pin, can also be implemented in other ways, such as by a motor or a magnetic drive device, or the locking pin could use gravity as a drive means.

The snare catch device can be installed in outward opening sashes of windows set in an opening of a building. However, it can also be provided in inward-opening sashes of windows built into an opening in a building.

This mobility can then be realized in various ways. Thus, the latching hook section can be pivotably arranged on the base. According to another variant, however, it can also be arranged displaceably on the base like a carriage.

According to a preferred embodiment, it can also be provided that the locking hook section on the base can be locked with the help of the locking pin in a release position is movable and that the locking hook section can be moved back into the locking position by means of a spring acting on it. This is a simple variant for moving the latching hook section back into its initial position. However, the backward movement could also take place in another way, for example magnetically or possibly with the aid of gravity as the drive means (with a corresponding installation position) or with another drive means.

It is structurally simple if the locking pin assembly has a guide housing from which the locking pin protrudes, the locking pin being able to be repeatedly pushed into the guide housing by a distance S from this position by pressing on its free end.

In order to implement the required functionality, that the latch catch device is released from the locking position by means of the locking rod fitting in such a way that it is moved from an open position into a locking position and then back into the open position, there are various options.

The latching hook section of the latch assembly can have a bearing surface on which the locking pin rests when it is latched to the latch assembly, the bearing surface being designed and arranged such that the locking pin protrudes only part of the distance S out of the guide housing. Provision can then also advantageously be made for the locking pin to be extended further out of the latched state after the locking bar fitting has been moved into a locking position than on the contact surface of the latching hook section, and for the locking pin to be retracted when the locking bar fitting is moved again from the locking position into the open position Latching hook section moves in such a way that re-opening of the wing is possible.

The invention also creates a simple and uncomplicated method for deactivating the latch catch device of a window or door according to one of the preceding claims, with which, when the sash is in the closed position and the latch catch device locks the sash on the frame, the latch catch device is released from the latching position by means of the locking bar fitting takes place in such a way that it is moved from an open position into a locking position and then back into the open position.

A functionally particularly safe and simple variant of this method is characterized in that the locking pin comes to rest on a support surface (of the latching hook section) when it latches on the latching hook section when the leaf is closed or closed, whereby it is not fully extended out of the guide housing and that it then, when the latch bar fitting is moved to its locking position, is moved laterally off the support surface so that it extends further out of the guide housing and then, when the latch bar fitting is moved back to its open position, the locking pin is moved against an edge of the support surface and then moves the latch hook portion to a release position so that the wing can be opened again.

Various exemplary embodiments are described in the following description of the figures. The individual features of these exemplary embodiments can advantageously be used in combination with the respective further features of the exemplary embodiments. However, they can also be combined with other exemplary embodiments, shown or not shown, and are also suitable in each case as advantageous refinements of the objects described in one or more of the main and subclaims. In the following, the term "window" can be replaced by "door".

1 shows a window. The window has a peripheral frame 1 . This is composed of several profiles - window frame profiles 10 - to form a frame shape, in particular a rectangular shape (on a door, the bottom of the window frame profiles can be designed as a threshold).

On the frame 1 relative to the frame 1 movable wing is arranged. The wing has a preferably peripherally closed wing frame 2 and an inserted into the wing frame 2 and received by this surface element 3 such as a glazing. The surface element 3 extends parallel to or in a plane that extends from the X and Y axes of the coordinate system in 1 is stretched. The casement 2 is composed of a plurality of casement profiles 20 to form a frame, in particular a rectangular shape.

The window frame profiles 10 and/or the casement profiles 20 can consist of any material, for example a plastic or a metal or a composite of such materials.

The sash can be moved from a closed position manually with a handle (or by a motor via a drive) into an open position and from this back into a closed position. For this purpose, it is rotatably mounted on the frame 1 by means of one or more rotary fittings. The axis of rotation is preferably a vertical axis (related to the installation position of the window in a building). The swivel fittings can also allow other movements (such as tilting movements about a horizontal axis of rotation, not shown). However, within the scope of this invention, this is merely an optional configuration. For the purposes of this document, the term “rotating” therefore also includes “tilting” or “pivoting” about a horizontal axis.

In the closed position, the sash is secured by means of a locking bar fitting 4, which has one or more locking bars 41 (see e.g 2c Which shows one of the locking rods in sections) and using corresponding locking elements on the sash 2 - are formed on the locking rod or rods 41 - and which are formed on the frame 1, locked. For the basic structure of locking bar fittings, see the example DE 10 2013 100 308 A1 referred.

The locking elements (not shown) can be designed in various ways, for example as locking pins or locking rollers, which are provided on one or more locking rods 41, which are arranged on the casement 2 so that they can move relative to it and are preferably connected by means of the handle or by means of the motor drive are movable, in particular along the associated casement profiles on which they are each arranged, are linearly movable. In corners corner deflections can be provided, which along the Flü Couple the locking bars provided for the gel frame profiles.

In order to lock the sash on the frame 1, the one or more locking rods 41 are preferably moved by turning a handle or another drive into a position in which the locking elements engage behind them in a locking manner corresponding abutments on the frame 1. This position is called the "locking position" of the lock bar fitting. To open the wing, the locking bar fitting 4 or its locking bars 41 are moved accordingly into a second position in which they do not reach behind the abutment. This position is called the open position of the locking bar fitting 4 . In this position, the sash can then be opened by turning it away from the frame 1.

The above structure has long been well known per se to those skilled in the art and does not require a more detailed description. Purely exemplary is on the DE 10 2013 100 308 A1 referred, which discloses such a structure.

If the locking bar fitting is in the open position and the sash has been rotated into an open position, it can happen that the sash - e.g. due to strong wind - is repeatedly opened and closed. This is avoided here.

This is achieved by an automatic latch catch--hereinafter also referred to as latch catch device 5--which holds the sash in the closed position of the sash after it has been slammed shut, without the locking bar fitting 4 having been or being moved into its locking position.

The latch catch device 5 has corresponding devices on the sash frame 2 and on the frame 1 . A locking pin assembly 51 of the latch catch device 5 is formed on the casement frame 2 and a latch assembly 52 of the latch catch device 5 is formed on the frame 1 (see FIG 2a) and b).

In 2a the locking bar fitting has been moved into an open position, ie the other locking elements (not shown here) on the locking bar or bars do not engage behind the abutments provided on the frame. Therefore, the wing can or could be moved to an open position. However, it can also be moved back into a closed position without moving the locking bar fitting and could possibly open during a storm, for example. and strike. This is prevented by the snare catch device 5. The production of rain and air tightness, however, is not a mandatory task of the snare catch or the snare catch device 5.

The snare catch device 5 is preferably arranged on the window opposite the handle, which is vertical in the normal installation position of the blind and sash frame profiles 10, 20. But this is not mandatory. You could also be formed on horizontal blind and casement profiles (not shown here). Then the locking rods 41 and the locking elements on the casement 2 move in the Y direction and in the opposite direction. When opening and closing, the sash moves almost parallel to the Z-direction at the beginning and towards the end of its movement.

The latch pin assembly 51 includes a guide housing 510 . This is fixed to the locking bar 41, so that the movements of the locking pin assembly 51 of the locking bar (in this example in the Y direction - perpendicular to the image plane of the 2a) can follow or follows. For this purpose, the guide housing 510 can have an (elongated) shape that allows it to be inserted into the locking rod 41 . It can be latched to this, for example (not shown in detail here).

On the guide housing 501 is a driven, preferably spring-loaded, locking pin 511 perpendicular to the sliding direction of the locking rod (here the Y-direction) movably guided (here in the closed position of the wing in and against the X-direction). It protrudes from the guide housing 510 with a free end. An energy accumulator, a spring 512, which can be a helical spring, for example, acts on it in the guide housing 510. The locking pin 511 can thus be pushed a little way into the guide housing 510 and automatically return to a further extended position by the drive, in particular by the spring 512 acting on it. When the locking pin is described below, what is meant is such a driven or spring-loaded locking pin.

According to a preferred embodiment, the locking pin assembly 51 can be inserted into a hole in the locking rod during fitting assembly, like a locking roller. The spring 512 pushes the locking pin 511 outwards. It can preferably be pressed fully into the guide housing 510 against the spring. The latch pin assembly 51 moves with the latch bar 41 which can be moved over the window handle, for example. The guide housing 510 can have a central opening which is closed by a plug 513 after the spring 512 and the locking pin 511 have been inserted. The term guide housing 510 should not be interpreted too narrowly. He also includes a base member that is not closed but supports and guides the moveable spring-loaded latch pin 511 .

The locking pin 511 thus protrudes spring-loaded from the guide housing 510 by a distance S and can be repeatedly pushed into the guide housing 510 by the distance S or part of the distance S from this position by pressing on its free end (see e.g 3b) .

The corresponding latch assembly 52 is formed on the parallel window frame profile 1 corresponding to the casement profile 20 . It has a latching hook section 521 or a latching hook section part. It may further include a base 522 . The latching hook section 521 - in the sense of a latching hook section part with several functions - is preferably arranged movably on the base 522 . The base 522 can be attached to the frame profile 10, for example screwed.

The latching hook section section 521 can in particular be arranged in a driven, preferably spring-loaded, movable manner on the base 522 . A drive, in particular a spring 523, acts on the latching hook section 521 in order to move it into a first defined position on the base 522, in particular to move it back

The latching hook portion 521 may be pivotally mounted on the base 522, for example. Such an embodiment example show the 2 and 3 . However, the latching hook section 521 can also be slidably arranged on the base 522 . Such an embodiment show the 6 until 8th .

The latching hook section 521 can be moved back and forth at least between a latched position and a release position. It can be moved into the release position by the locking pin 511 and back into the locked position with the drive means, in particular the spring 523.

In the release position, the sash can be opened. In the detent position or detent position, on the other hand, it is held by the latch catch device 5 on the frame 1 when the sash has been closed or closed, although the handle has not yet been turned to "locked".

It is preferred that the locking hook section 521 is automatically pushed or moved into the locking position by the action of the spring 523, which can be a torsion spring, for example, when it has left the locking position in which the locking pin 511 can be locked on it.

The latching hook section 521 can, for example, be arranged on the base 522 such that it can be pivoted about an axis of rotation perpendicular to the sliding direction Y of the locking rod 41 of the adjacent frame profile 10 . But it can also - be slidably arranged on the window frame profile - preferably parallel to the direction of displacement of the locking rod 41. The latching hook section 521 includes the actual latching nose/latching edge 5214 and a support area 5212, on which the locking pin can rest in the latched state. The latter has a side edge 5213 . The support area 5212 is above the base. The locking pin 511 can rest on the support area 5212 in the locking position of the latch catch device. Then he is partially extended. However, it can also rest on the base 522 (or possibly another “lower level”). Then it is further extended out of the guide housing 510 .

The spring 523 can be designed as a torsion spring, for example. However, the spring 523 can also be designed, for example, as a helical spring or the like.

• Die Rastnase 5214 des Rasthakenabschnitts 521 befindet sich in einem Zustand, in welchem der Flügel 2 geöffnet worden ist, bereits vorbereitend quasi „wartend“ in der „Raststellung“ (2a, 2c, 5a). Dem entspricht, dass sich der Riegelstangenbeschlag und ggf. dessen Handgriff in „Offenstellung“ befinden. Der Riegelzapfen 511 ist aber noch nicht an ihr verrastet worden.

This operation of this arrangement is as follows:

• The latching lug 5214 of the latching hook section 521 is in a state in which the leaf 2 has been opened, already in preparation, quasi "waiting" in the "latched position" ( 2a , 2c , 5a) . This corresponds to the fact that the locking bar fitting and, if applicable, its handle are in the "open position". However, the locking pin 511 has not yet been locked onto it.

If the sash is now closed in the Z-direction - be it by closing it manually or, for example, by being hit by the wind - the locking pin 511 with the sash is attached to the residual hook 511 ( 2a) approached. The locking lug 5214 can have a run-up ramp 5211, which is designed in such a way that the locking pin 511 is pushed further and further into the guide housing 510 when the sash is closed further, until the free end of the locking lug 5214 is crossed, so that the spring-loaded locking pin 511 moves further again can drive out. In this position, the locking pin 511 is locked “behind” the locking hook section 521 in a locking position of the latch catch device 5 . It lies on a support surface 5212 of the latching hook section 521, whereby it is not fully extended out of the guide housing 510 ( 5b) . The bearing surface 5212 can have lateral ramps, so that the locking pin 511 is additionally secured in position. The start-up ramp 5211 can also have a braking effect.

In the locking position, in which it has crossed the free end of the locking hook section 521, the locking pin 511 can rest on the bearing surface 5212. The height of this bearing surface 5212 (see also 5a) is such that the locking pin 511 rests on it, but is not fully extended from the guide housing 510.

The locking pin 511 is now in a position in which it cannot be released from the detent position simply by moving the wing. Rather, it is necessary to release the latch catch device 5 manually from its locked position. This still corresponds to a handle position of the sash in the open position.

The latch catch device can be released from its locking position in a simple manner by moving the locking rod fitting 4 into its locking position and from there back into the open position. Because if the locking bar 41 is linearly displaced, here in the +Y direction or -Y direction, the locking pin 511 is moved laterally past the latching lug 5214 and down from the bearing surface 5212, so that the latching between the locking pin 511 and the latching hook section 521 will be annulled ( 5c ).

This corresponds to the fact that the locking fitting 4 is in the locking position. The wing 2 is thus indeed locked on the frame 1. However, this locking is now achieved by the additional locking elements such as the additional locking pins or closing rollers or the like of the window, which engage behind the corresponding fixed locking elements such as the abutments on the window frame 1 . In contrast, the locking pin 511 is in a position next to the latching hook section 521 in which it is not latched to the latching hook section 521 ( 5c ).

If the sash is now to be opened again, the locking elements, which engage behind the corresponding abutments on the window frame 10, are moved out of this grip by moving the locking rod 41 or the locking rod fitting into the open position.

So that the window or its sash can be opened again, the locking pin 511 must not be moved back into the locking position in which it engages behind the locking hook section 521 in a locking manner. Because then the wing could not be turned up.

To solve this problem, the locking hook section 521 and the locking pin 511 are coordinated in such a way that the locking pin, which was extended further after leaving the support surface 5212 after the locking bar fitting 4 was moved into the locking position, when the locking bar fitting is moved back and thus also when it is moved back of the locking bar 4 on which it is seated, initially strikes the edge of the 5213 of the latching hook section 521 laterally in the open position, whereby it then moves the latching hook section 521 into a position, here into a release position, which is a pivoting position here 5d ). Since the locking hook section has now been moved “to the side”, so to speak, the sash can be opened because the locking lug 5214 is not in the way of the locking pin (here in the Z direction).

This can be summed up in other words. If the locking pin 511 is moved in the +Y direction or -Y direction when the locking bar 41 is moved when the locking bar fitting is moved into its locking position, the locking pin 511 is moved laterally down from the bearing surface 5212 so that it further protrudes from the guide housing 510 can extend and can come to rest on the base 522, for example. When this locking bar 41 is moved back, when the locking bar fitting 4 is moved back into its open position, the locking pin 511 moves against an edge 523 of the bearing surface 522 and moves the latching hook section 521 into a release position ( 5d ) so that the sash can be opened again.

In this state, the spring 523, in particular the torsion spring, tensioned by the movement--in particular pivoting--of the latching hook section 521 can then relax. The spring 523 then moves the latch hook portion 521 back to its latched position ( 5a) , So that the case catch device 5 is activated again or in the starting position of 5a moved back so that it can be used again.

Provision can be made for the locking position to be defined by a stop of the spring 523 or the locking hook section 521 on the base 522 .

The movement of the latching hook section 521 into the release position can also be limited by a lateral stop 5221, for example on the base 522. Two end stops 5221, 5221 can be provided in opposite directions, in particular pivot directions. Provision can also be made for the latching hook section 521 to be deflectable in two directions of rotation, starting from the latched position. For this purpose, the spring, here the torsion spring 523, can be designed in such a way that it moves the locking hook section 521 from the two end positions at the end stops 5221, 5221 into the middle locking position can turn back ( 4e) . In this way, the latch catch device 5, which can be actuated from two directions, can be used or installed independently of the direction of movement of the locking rod 4 when locking or opening a window.

Leaving the support surface 5212 behind the locking lug 5214 by the locking pin 511 is positively controlled in the embodiment described above as well as in other embodiments of the invention. Preferably, the latching lug 511 runs onto the stop in the direction of the locking position after approximately half the pivoting movement (locking rod stroke), ie for example after 10 mm. The locking pin 511 must now leave the area of the locking lug 5214 when the locking bar fitting 4 is actuated further by the handle in the direction of the locking position (which is reached after 20 mm, for example), even if it had pulled it here due to friction

Alternatively, the functionality described above can also be implemented on a latch catch device 15 which has a sled-like latching hook section 1521 that is displaceably arranged on the base 1522 . Casement side, for example, again the locking pin assembly 51 of 3a) until 3c ) may be provided on the casement profile 20.

The latch assembly 152 is in turn arranged on the window frame side. Its fixed lower part or its base 1522 is screwed to the frame 1 or a frame profile 10 . It has a locking hook section 1522 that can be moved on guides in the longitudinal direction of the profile, which is designed as a linearly movable carriage and in turn contains a locking lug 15214 . This carriage is preferably held centrally on the base 1522 by means of at least one spring 1523, here by means of two compression springs 1523, but can be displaced parallel to the direction of movement of the locking rod of the adjacent casement profile against the spring force.

• Zunächst befindet sich der Riegelstangenbeschlag in der Offenstellung (Griffstellung des Flügels: geöffnet). Dies ist in 8a schematisch dargestellt. Der Flügel ist jetzt aufgedreht worden. Wird der Flügel nun zum Blendrahmen 1 bewegt und zugedrückt, kann der Riegelzapfen 511 hinter die Rastnase bzw. hinter den Rasthakenabschnitt 1521 der Fallenbaugruppe 152 schnappen. Zur Erleichterung dieser Bewegung hat die Rastnase bzw. hat der Rasthakenabschnitt vorzugsweise wieder eine Auflauframpe 15211, die ein Einfedern des Riegelzapfens 511 während der Schließbewegung des Flügels begünstigt (8b) und ggf. die Bewegungsgeschwindigkeit des Flügels bremst. Der Riegelzapfen 511 der Fallenschnäppereinrichtung 15 ist teilweise aber nicht ganz ausgefahren und liegt jetzt auf dem Auflagebereich 15212. Der Flügel ist nun festgesetzt.

The trap assembly works here as follows:

• First, the locking bar fitting is in the open position (handle position of the sash: open). this is in 8a shown schematically. The wing has now been turned up. If the sash is now moved towards the frame 1 and pressed shut, the locking pin 511 can snap behind the latching lug or behind the latching hook section 1521 of the latch assembly 152 . To facilitate this movement, the latching lug or the latching hook section preferably again has a run-up ramp 15211, which promotes a deflection of the locking pin 511 during the closing movement of the leaf ( 8b) and, if necessary, slows down the movement speed of the wing. The locking pin 511 of the latch catch device 15 is partially but not fully extended and is now lying on the support area 15212. The wing is now fixed.

Now the locking bar fitting 4 is moved into the locking position (handle position of the wing: locked/closed). this is in 8c shown schematically. The sash is locked using its standard locking elements such as closing rollers and locking pieces. In this position, the locking pin 511 of the latch catch device 15 has been pulled laterally behind the detent 15214 of the latch assembly 152 (eg in or against the vertical Y-direction). In this way, he has crossed the contact area 5212 of the latching hook section 1521, which can be provided with further approach ramps to facilitate this movement, and thus left it. The locking pin 511 of the case catch device 15 is now at a lower level. or is extended further than on the support area 15212. It can be a lower support of the base or, as here, of the slide-like latching hook section 5212 itself.

The locking bar fitting 4 is now moved back into the open position (handle position of the sash: open). this is in 8c shown schematically. The locking pin assembly 51 moves with the locking bar 41 in the direction of the locking hook section 1521 of the latch assembly 152. However, the locking pin 511 cannot get back into the area of the bearing surface 12512 behind the locking lug 15214, since this has no run-up ramps on its outside, but is a vertical edge 15213 . The carriage is therefore moved laterally on its guide until the handle is fully open. When the locking bar fitting 4 is fully moved to the open position, the locking pin 511 is still next to but not behind the detent 15214. The wing can now be pushed open. The locking pin 511 leaves the carriage-like locking hook section 1521, which is then centered again by its two compression springs. The locking mechanism is thus reactivated.

This latch assembly is also preferably constructed symmetrically. It can be used regardless of the direction of movement of the lock bar, without the need for right and left parts. Leaving the support area 15212 behind the locking lug 15214 by the locking pin 511 is positively controlled here as well: The slide-like locking hook section 1512 is already after about half a handle stroke (locking rod stroke) In the direction of the locking position at the movement limit stop of the carriage, ie after 10 mm, for example. The locking pin 511 must now leave the contact area 15212 behind the locking lug 15214 when the handle is actuated further in the direction of the closed position (e.g. reached after 20 mm), even if it had pulled the locking hook section 1512 with it up to here.
