Description

Window or door

Technical Field

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

Background

In order to limit or prevent dynamic and in individual cases self-destructive movements of the window leaf, for example, due to wind, it is desirable for such a window leaf to be locked to the housing after the slamming (Zuschlagen) even in the absence of movement of the locking lever fitting. Further movement of the wing from the locked position should first be initiated by the user. The locking lever fitting is disclosed, for example, in DE102013100308 A1.

Disclosure of Invention

The object of the present invention is to solve the above-mentioned problems and to provide a correspondingly designed window or a correspondingly designed door.

The present invention solves the problem by the subject matter of independent claim 1. Advantageous embodiments can be derived from the dependent claims.

According to claim 1, a window or door is provided, which has a chamber frame consisting of a plurality of chamber frame profiles and a wing which is arranged on the chamber frame in a rotatable manner about a horizontal or vertical axis of rotation, which is assembled from a plurality of wing frame profiles, on which wing frame a locking lever fitting is also provided which has one or more locking levers with which a first locking element can be moved into a locking position for back-engaging the respective locking element on the chamber frame and moving back into an open position, and which is provided with a latching catch arrangementWith this latching catch device, even when the locking lever device is in the open position and the wing is closed after opening, the wing can be locked to the housing in the locking position, wherein the latching catch device is released from the locking position by means of the locking lever fitting such that the locking lever fitting moves from the open position into the locking position and then back into the open position.

This has several advantages. By automatically activating the latching catch, the wing can be locked or fastened to the housing in a snap-locking manner in a simple manner when the door is closed. In this way, the wing is locked onto the bore frame by the latch catch means after slamming (and also after slow closing) without the locking bar fitting moving into its locked position. It is then particularly advantageous that the latching catch can be deactivated simply (for example by moving the handle into the latched position and then back into the open position). Since, surprisingly, no additional manual intervention is required for actuating the window in spite of the latching catch, except for the movement of the locking lever fitting into the locking position, which is normally required in this case after the wing has been closed firmly, for example by wind, to lock the wing, and then (immediately or later) back into the open position when the wing should be opened.

It is preferred (because of the structural simplicity) that the latch catch device has a locking pin assembly arranged on the at least one movable locking lever of the wing frame, which locking pin assembly has a locking pin movable, preferably spring-loaded, by the drive mechanism, and that the latch catch device has a latch assembly arranged on the bore frame, which latch assembly has a base and a latching hook section with a latching projection behind which the spring-loaded locking pin is locked in the latched position. In this case, it can be provided, in addition, according to a particularly preferred variant, that the latching hook section is arranged movably on the base and the base is fixed immovably on one of the bore frame profiles of the bore frame, wherein the latching hook section can be moved back and forth on the base between the release position and the latching position. The drive mechanism acting on the locking pin may be a spring. The spring acting on the locking pin can be designed in different ways, i.e. as a helical spring or a cup spring or an elastomer spring or the like. However, the drive mechanism acting on the locking pin can also be realized in other ways, i.e. by means of a motor or a magnetic drive, or the locking pin can use gravity as the drive mechanism.

The latch catch may be fitted into an outwardly opening wing of a window inserted into an opening of a building. But it may also be provided in an inwardly opening wing of a window inserted into an opening of a building.

This mobility can then be achieved in different ways. The catch hook section can thus be arranged pivotably on the base. However, according to another variant, it can also be arranged on the base so as to be movable as a slide.

According to a preferred embodiment, it can be further provided that the latching hook section is movable on the base by means of a latching pin into the release position and that the latching hook section is movable by means of a spring acting on it back into the latching position. This is a simple variant in order to move the catch hook section back into its starting position. However, this return movement can also be effected in other ways, for example magnetically or optionally by means of gravity as a drive (in the corresponding installation position) or by means of other drive means.

The locking pin assembly has a guide housing from which the locking pin protrudes, wherein the locking pin can be repeatedly pushed into the guide housing from the position by pressure on its free end for a distance S.

In order to achieve the required functionality, the latching catch is released from the latching position by means of the latching lever fitting in such a way that the latching lever fitting is moved from the open position into the latched position and then back into the open position, there are different options.

The latching hook section of the latch assembly can therefore have a bearing surface on which the latching pin rests in the state in which it is locked to the latch assembly, wherein the bearing surface is designed and arranged such that the latching pin protrudes from the guide housing only for a portion of the distance S. It can then be provided further advantageously that the locking pin is moved out of the locked state after the locking pin fitting has been moved into the locked position, further than on the contact surface of the locking hook section, and that the locking pin moves the locking hook section when the locking pin fitting is moved back from the locked position into the open position, in such a way that the wing can be opened again.

According to the invention, there is also provided a simple and uncomplicated method for deactivating a latching catch of a window or door according to any one of the preceding claims, with which, when the wing is in the closed position and the latching catch latches the wing on the bore frame, the latching catch is released from the latching position by means of the locking lever fitting such that the locking lever fitting moves from the open position into the latching position and then back into the open position.

A particularly functionally reliable and simple variant of the method is characterized in that, when the wing is closed or locked, the locking pin is placed against the bearing surface (of the locking hook section) when locked on the locking hook section, wherein the locking pin is not completely removed from the guide housing and, when the locking lever fitting is moved into its locked position, the locking pin is then moved laterally downward from the bearing surface, so that the locking pin is further removed from the guide housing, and, when the locking lever fitting is moved again into its open position, the locking pin is then moved against the edge of the bearing surface and then the locking hook section is moved into the release position, so that the wing can be opened again.

Detailed Description

Various embodiments are described in the following drawings. Various features of the embodiments may be advantageously used in combination with corresponding other features of the embodiments. They can also be combined with other embodiments shown or not shown and are also suitable as advantageous designs for the subject matter described in the respective or more independent and dependent claims. The term "window" may be replaced by a "door" in the following.

Fig. 1 shows a window. The window has a surrounding bore frame 1. The box is assembled from a plurality of profiles (box profile 10) into a frame shape, in particular a rectangular shape (on a door, the lower of the box profiles may be configured as a door sill).

A wing movable relative to the bore frame 1 is arranged on the bore frame 1. The wing has a preferably circumferentially closed wing frame 2 and a face element 3, such as a glazing, inserted into and received by the wing frame 2. The surface elements 3 extend parallel or in planes which are spanned by the X-axis and the Y-axis of the coordinate system in fig. 1. The wing frame 2 is assembled from a plurality of wing frame profiles 20 into a frame shape, in particular a rectangular shape.

The cavity frame profile 10 and/or the wing frame profile 20 may be made of any material, for example of plastic or metal or of a composite of such materials.

The wing can be moved manually by means of a handle (or motor-driven by a drive device) from the closed position into the open position and from there back into the closed position. For this purpose, the wing is rotatably supported on the bore frame 1 by means of one or more rotation stops. The axis of rotation is preferably a vertical axis (relative to the mounting position of the window in the building). The rotation stop may also allow further movement (e.g. tilting movement about a horizontal rotation axis, not shown). However, this is only an alternative design within the scope of the invention. Thus, the term "rotation" also includes "flipping" or "pivoting" about a horizontal axis in the sense of this document.

In the closed position, the wing is locked by means of a locking lever fitting 4 having one or more locking levers 41 (see, for example, fig. 2c, which shows one of the locking levers in part) and by means of a corresponding locking element formed on the wing frame 2 (on the locking lever or levers 41) and on the bore frame 1. For the basic structure of the locking lever fitting, reference is made for example to DE102013100308A1.

The locking elements (not shown) can be embodied in various ways, for example as locking pins or locking rollers, which are arranged on one or more locking bars 41, which are arranged movably relative to them on the wing frame 2 and which are preferably movable by means of a handle or by means of a motor-driven drive, in particular linearly movable along the associated wing frame profile, on which they are arranged in each case. In the corners, there may be provided corner turns, which are each coupled to a locking lever provided along the wing frame profile.

In order to lock the wing to the housing 1, the one or more locking levers 41 are preferably moved by rotating the handle or the further drive device into a position in which the locking element engages behind its corresponding abutment on the housing 1. This position is referred to as the "latched position" of the detent lever assembly. For opening the wing, the locking lever fitting 4 or its locking lever 41 is correspondingly moved into a second position in which the locking lever fitting has no rear abutment. This position is referred to as the open position of the locking lever fitting 4. In this position the wing can then be opened in such a way that the wing is turned away from the bore frame 1.

The above-described structures are well known per se to the person skilled in the art and need not be shown in detail. See DE102013100308A1 for a mere example, which discloses such a structure.

If the locking lever fitting is in the open position and the wing has been rotated into the open position, it may occur that the wing is bumped and slammed shut, for example, due to strong winds (if necessary repeatedly). This is avoided here.

This is achieved by an automatic latching catch (also referred to below as latching catch means 5) which holds the wing in its closed position after the wing has been closed, without the locking lever fitting 4 being moved into its locking position.

The latch catch means 5 have corresponding means on the wing frame 2 and the bore frame 1. A locking pin assembly 51 of the latch catch device 5 is configured on the wing frame 2 and a latch assembly 52 of the latch catch device 5 (see fig. 2 a) and 2 b) is configured on the bore frame 1).

In fig. 2a, the locking lever fitting has been moved into the open position, i.e. the remaining locking element (not shown here) on the locking lever or levers has no abutment provided on the bore frame with a rear face. The wing can thus be moved or can be moved into the open position. However, the wing can also be moved again into the closed position without movement of the locking lever fitting and can possibly be bumped and slammed shut if necessary, for example in a storm. This obstructs the latch catch means 5. In contrast, the establishment of water-tightness and air-tightness is not a mandatory task for the latching catches or latching catch means 5.

The latching catch 5 is preferably arranged opposite the handle on the window on the vertical bore frame profile 10 and the wing frame profile 20 in the normal installed position. But this is not mandatory. They may also be constructed on horizontal bore frame profiles and wing frame profiles (not shown here). Then, the lock lever 41 and the lock member on the wing frame 2 move in the Y direction and against the direction. The wing moves almost parallel to the Z direction at the beginning and end of its movement when opening and closing.

The locking pin assembly 51 has a guide housing 510. The guide housing is fixed to the locking lever 41 so as to follow or be able to follow the movement of the locking pin assembly 51 of the locking lever (here, for example, in the Y direction, perpendicular to the plane of the drawing of fig. 2 a). For this purpose, the guide housing 510 may have an (elongated) shape, which allows it to be inserted into the locking lever 41. The guide housing may, for example, be locked to the locking lever (not shown in detail here).

On the guide housing 501, a driven, preferably spring-loaded locking pin 511 is guided movably perpendicular to the direction of movement of the locking lever (here the Y direction) (here in the closed position of the wing, i.e. towards and against the X direction). The locking pin protrudes with a free end from the guide housing 510. In the guide housing 510, an accumulator, a spring 512, which may be a coil spring, for example, acts on the locking pin. The locking pin 511 can thus be pressed into the guide housing 510 a distance and automatically returned again into the further removed position by the drive, in particular by the spring 512 acting on it. When the locking pin is described next, it is referred to as such a driven or spring loaded locking pin.

According to a preferred embodiment, the locking pin assembly 51 can be inserted into a hole of the locking pin, such as a closure roller, during assembly of the fitting. The spring 512 presses the locking pin 511 outward. The locking pin may preferably be fully compressed into the guide housing 510 against the spring. The locking pin assembly 51 moves with the locking lever 41, which may be moved, for example, via a window handle. The guide housing 510 may have a central opening, which is closed by a plug 513 after insertion of the spring 512 and the locking pin 511. The term "guide housing 510" should not be construed too narrowly. It also includes a base element that is not of closed construction but supports and guides a movable, spring-loaded locking pin 511.

Thus, the locking pin 511 protrudes from the guide housing 510 in a spring-loaded manner by a distance S and can be repeatedly pushed from said position into the guide housing 510 by pressure on its free end by said distance S or a part of said distance S (see, for example, fig. 3 b).

A corresponding latch assembly 52 is constructed on the parallel bore frame profile 1 corresponding to the wing frame profile 20. The latch assembly has a latching hook section 521 or a latching hook section component. The latch assembly may also have a base 522. The latching hook section 521 (in the sense of a latching hook section component having multiple functions) is preferably arranged movably on the base 522. The base 522 may be secured, such as by threading, to the bore frame profile 10.

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

The shackle segment 521 may be pivotably disposed on the base 522, for example. Such an embodiment is shown, for example, in fig. 2 and 3. The snap hook section 521 may be movably disposed on the base 522. Fig. 6 to 8 show such an embodiment.

The latching hook section 521 is reciprocable at least between a latching position and a release position. The latching hook section can be moved by the latching pin 511 into the release position and by means of the drive, in particular the spring 523, back into the latching position.

In the released position, the wing can be opened. Conversely, when the wing is closed or shut, although the handle has not been turned "latched", in the latched position the wing is held on the bezel 1 by the latch catch 5.

Preferably, when the latching hook section has left the latching position, in which the latching pin 511 can be latched thereon, the latching hook section 521 is automatically pushed or moved into the latching position by the action of a spring 523, which may be a helical torsion spring, for example.

The latching hook section 521 can be arranged pivotably on the base 522, for example, about an axis of rotation perpendicular to the sliding direction Y of the latching lever 41 of the adjacent bore frame profile 10. But it may also be arranged on the bore frame profile, preferably displaceably parallel to the direction of movement of the locking bar 41. The latching hook section 521 comprises the actual latching projection/latching edge 5214 and a support area 5212 on which the latching pin can be placed in the locked state. The latter having lateral edges 5213. The support region 5212 is located above the base. The locking pin 511 can be placed on the bearing area 5212 in the locked state of the latch catch. The locking pin is then partially removed. But the locking pin may also be placed on the base 522 (or on another "deeper plane" if desired). The locking pin is then further removed from the guide housing 510.

The spring 523 may be configured as a helical torsion spring, for example. However, the spring 523 may be configured as a coil spring or the like, for example.

The way this arrangement works is as follows:

the latching projection 5214 of the latching hook section 521 is in a state in which the wing 2 has been opened and is ready to be approximately "waiting" in the "latched state" (fig. 2a, 2c, 5 a). This corresponds to the locking lever fitting and its handle being in the "open position" if necessary. But the locking pin 511 has not yet been locked thereto.

If the wing is now closed in the Z-direction (whether by manual closing or e.g. due to wind impact), the locking pin 511 moves with the wing close to its catch hook 511 (fig. 2 a). The latching projection 5214 can have a starting ramp 5211 which is designed such that the locking pin 511 is still pressed further into the guide housing 510 when the wing is further closed, until the free end of the latching projection 5214 is traversed, so that the spring-loaded locking pin 511 can be moved out again further. In this position, the locking pin 511 locks "behind" the latching hook section 521 in the latched position of the latching catch 5. The locking pin rests on the bearing surface 5212 of the latching hook section 521, wherein the locking pin is not completely removed from the guide housing 510 (fig. 5 b). The bearing surface 5212 can have a lateral slope, so that the locking pin 51 is additionally fixed in position. The starting ramp 5211 can also act as a brake if desired.

The locking pin 511 can rest against the support surface 5212 in the locked position in which it has traversed the free end of the locking hook section 521. The height of the bearing surface 5212 (see also fig. 5 a) is such that the locking pin 511, although located on the bearing surface, has not yet been completely removed from the guide housing 510.

The locking pin 511 is now in a position in which it can no longer be released from the locking position merely by the movement of the wing. Rather, the latching strike 5 needs to be released manually from its latched position. This always corresponds to the handle position of the wing in the open position.

The release of the latching catch from its latching position can be achieved in a simple manner by moving the latching lever fitting 4 into its latching position and from there back into the open position. Because the locking lever 41 moves linearly, in this case in the +y direction or-Y direction, the locking pin 511 moves laterally past the locking projection 5214 and downward from the bearing surface 5212, so that the locking between the locking pin 511 and the locking hook section 521 is released (fig. 5 c).

This corresponds to the latching fitting 4 being in the latched position. Thus, the wing 2 is locked to the chamber frame 1. However, this locking is now achieved by other locking elements of the window, such as other locking pins or closing rollers or the like, which engage behind corresponding fixed locking elements, such as seats on the housing 1. Conversely, the locking pin 511 is in a position next to the latching hook section 521, in which position the locking pin is not locked to the latching hook section 521 (fig. 5 c).

If the wing should now be opened again, the locking element which engages the corresponding abutment on the rear side of the housing frame 10 is moved out of the rear side engagement into the open position by the movement of the locking lever 41 or the locking lever fitting.

In order to allow the window or its wing to be opened again, the locking pin 511 is now not allowed to move again into a locking position in which it engages back in the locking hook section 521. Because the wing cannot be unscrewed accordingly.

In order to solve this problem, the latching hook section 521 and the latching pin 511 are coordinated with one another in such a way that, after the release from the support surface 5212, the latching pin which is moved out further after the latching lever fitting 4 has moved into the latching position, initially comes to rest laterally against the edge of the latching hook section 521 at the time of the return movement of the latching lever fitting and thus of the latching pin lever 4 which is provided in the open position, wherein the latching pin then moves the latching hook section 521 into the position in which it is moved into the release position, which is the pivoted position (fig. 5 d). Since the latching hook section now moves somewhat "sideways", the wing can be opened, since the latching projection 5214 does not block the latching pin (here in the Z direction).

This is briefly summarized in other words. If the locking pin 511 moves in the +y direction or in the-Y direction when the locking lever 41 is moved, when the locking lever fitting is moved into its locked position, the locking pin 511 moves laterally downward from the support surface 5212, so that it can be moved out of the guide housing 510 further and can rest against the base 522, for example. When the locking lever 41 is moved back, when the locking lever fitting 4 is moved again into its open position, the locking pin 511 moves against the edge 523 of the bearing surface 522 and moves the catch hook section 521 into the release position (fig. 5 d), so that the wing can be reopened.

In this state, the spring 523, in particular the helical torsion spring, which is tensioned by the movement, in particular the pivoting, of the latching hook section 521 can then be released. The spring 523 then moves the latching hook section 521 back into its latching position (fig. 5 a), so that the latching catch 5 is activated again or moves back into the starting position of fig. 5a, so that it can be used again.

It can be provided that the latching position is defined by a stop of the spring 523 or the latching hook section 521 on the base 522.

Movement of the latching hook section 521 into the release position can also be defined by a lateral stop 5221, for example, on the base 522. Two end stops 5221, 5221 can be provided in opposite directions, in particular in the pivoting direction. It can furthermore be provided that the latching hook section 521 is pivotable in both directions of rotation, starting from the latching position. For this purpose, the spring, here the helical torsion spring 523, can also be designed such that it can pivot the latching hook section 521 from the two end positions at the end stops 5221, 5221 back into the then intermediate latching position (fig. 4 e). In this way, the latch catch 5, which can be actuated from both directions, can be inserted or mounted on the window during locking or unlocking, independently of the direction of movement of the locking lever 4.

In the above-described embodiment and also in other embodiments of the invention, the removal of the bearing surface 5212 behind the latching projections 5214 by the latching pins 511 is positively controlled. Preferably, the latching projection 511 runs onto the stop after approximately half a pivoting movement (latching lever travel) in the direction toward the latching position, i.e. after 10mm, for example. Thus, when the locking lever fitting 4 is further actuated by the handle in the direction of the locking position (for example, reached after 20 mm), the region of the locking projection must be moved away even if the locking pin has pulled the locking projection 5214 together due to friction.

Alternatively, the above-described functionality can also be implemented on a latch catch device 15 having a slide-shaped latching hook section 1521 which is movably arranged on the base 1522. The locking pin assembly 51 on the side of the wing frame, for example in fig. 3 a) to 3 c), can in turn be arranged on the wing frame profile 20.

A latch assembly 152 is again provided on the bore frame side. The fixed lower part thereof or the base 1522 thereof is screwed to the bore frame 1 or the bore frame profile 10. It has a latching hook section 1522 which is movable in the longitudinal direction of the profile on a guide, is designed as a linearly movable slide and in turn comprises a latching projection 15214. The slide is held, preferably centered, on the base 1522 by means of at least one spring 1523, in this case by means of two pressure springs 1523, but can be displaced against the spring force parallel to the direction of movement of the locking bars of the adjacent wing frame profiles.

The latch assembly works here as follows:

First, the locking lever fitting is in the open position (handle position of the wing: open). This is schematically shown in fig. 8 a. The wing has now been unscrewed. If the wing is now moved toward the bore frame 1 and pressed, the locking pin 511 can snap behind the locking projection or behind the locking hook section 1521 of the latch assembly 152. To facilitate this movement, the latching projection or the latching hook section preferably has a further rising ramp 15211 which, during the closing movement of the wing, facilitates the spring compression of the latching pin 511 (fig. 8 b) and, if appropriate, brakes the movement speed of the wing. The locking pin 511 of the latch catch 15 is partially but not completely removed and now lies on the bearing region 15212. The wing is now fixed.

The locking lever fitting 4 is now moved into the locked position (handle position of the wing: locked/closed). This is schematically shown in fig. 8 c. The wings are locked by means of their standard locking elements such as a closing roller and a locking element. The locking pin 511 of the latch catch 15 is pulled away laterally behind the latching projection 15214 of the latch assembly 152 in this position (e.g., in the vertical Y-direction or opposite the vertical Y-direction). It traverses in this way and thus leaves the bearing region 5212 of the latching hook section 1521, which may be provided with a further rising ramp in order to facilitate this movement. The locking pin 511 of the latching strike 15 is now located at a lower level or is moved out farther than on the bearing region 15212. This may be the lower support of the base or the lower support of the slide-shaped latch hook section 5212 itself.

The locking bar fitting 4 is now moved back into the open position (handle position of the wing: open). This is schematically shown in fig. 8 c. The detent pin assembly 51 moves in the direction of the detent pin lever 41 toward the detent hook section 1521 of the latch assembly 152. However, the locking pin 511 cannot return into the region of the bearing surface 12512 behind the latching projection 15214, since it does not have a starting ramp on its outer side, but rather a vertical edge 15213. The slide is thus moved laterally on its guide until the handle is fully opened. When the locking lever fitting 4 is completely moved into the open position, the locking pin 511 is still located beside the latching projection 15214, but not behind the latching projection 15214. The wing can now be pressurized. The locking pin 511 here leaves a slide-shaped latching hook section 1521, which is then centered again by its two pressure springs. Thus, the latch mechanism is again activated.

The latch assembly is also preferably symmetrically configured. It can be used irrespective of the direction of movement of the lock lever without having to give the right and left portions. In this case, too, the locking pin 511 is forced out of the bearing area 15212 behind the locking projection 15214: after approximately half of the handle travel (locking lever travel), the slide-shaped latching hook section 1512 is already located on the movement limiting stop of the slide in the direction of the locked position, i.e. after 10mm, for example. Thus, the locking pin 511 must now leave the bearing region 15212 behind the latching projection 15214 when the handle is further actuated in the direction of the locked position (for example after reaching 20 mm), even if it has pulled the latching hook section 1512 together.
