Abstract

A method for securing double doors or windows with a fixed central pillar has an interlocking catch operated by the locking mechanism. One part of the catch has a socket attached to the locking mechanism while the other frame has a mushroom shaped peg mounted on the locking mechanism and engaging the socket on the other frame. The locking action applies in both the fully closed or tilt ventilation settings of the door or window.

Description

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

Windows, doors od. Like. This genus are already known, as can be seen for example from DE 34 46 215 C2.

In this known window or door, which is also referred to as Stulpflügel- window or - door, an anti-burglary protection is provided which has at least two by a vertical frame legs separated wings, with a independently operable in each wing espagnolette, of which at least one as a turn-tilt fitting and the other is designed as a rotary fitting. The drive rod of the rotary wing fitting has a lower, deflected in a horizontal course drive belt with a locking element. Furthermore, a coupled with the tilt and turn fitting via a driving clutch and slidable in the horizontal frame legs of the adjacent wing actuator is provided which is provided with a latch member and the latch member is locked in the tilt position of the tilt and turn a part belonging to the locking element of the wing to be secured stop, so the rotary wing is prevented from opening. In this case, the locking member of the actuator is provided on its side facing away from the locking surface, with a run-on slopes, which is located in the adjustment of the deflected drive belt stop and ensures that the stop comes to rest after passing the chamfers on the locking surface of the latch member when the rotary wing is closed coming from the open position in tilted tilt and turn wings. As a result, the rotary wing is secured against burglary by the described connection with tilted active leaf. When the turn-tilt wing is closed, however, there is no burglar alarm.

Furthermore, from DE-PS 850 701 a closure assembly for two-leaf, outwardly rising window has become known, in which a known espagnolette is arranged on the inside of the cover strip of the first-striking window sash, which has at the point of impact protruding pin which is in latch on engage the second window sash while pushing or pulling the latches up or down into the window frame. Since the first sash is held behind the outer stop bar of the second sash, a special determination of the first sash is unnecessary.

In addition, such a fitting from the German patent DE 44 30 376 A1 is known. In this known fitting is a fitting for a lower door leaf pivotally mounted about a vertical axis, with an upper door leaf pivotally mounted on the door frame above the lower door leaf about the axis. Both door leaves are provided with an espagnolette element which carries a cooperating with a door frame side counter locking element locking element. An actuating element provided on the upper and / or lower door leaf for moving the respective drive rod element can be brought between the following functional positions: common locking position in which both door leaves are locked on the door frame in the closed position; common rotary readiness position in which both door leaves are rotatable together; Single turn-ready position, in which one of the two door leaves is locked on the door frame in the closed position and the other door leaf is rotatable. A drive rod coupling device for the drive rod elements of both fitting assemblies, which is releasable in the single rotation standby position by pivoting open the other door leaf, comprises a driving element with a driving opening on one of the two driving rod elements and engaging in the driving opening and the rotational opening of the other door leaf in the individual Rotational readiness position emerging from the driving opening Carrying projection on the other drive rod element. Further, a door leaf coupling device is provided for both door leaves for pivotal coupling in the common rotational readiness position and decoupling in the single rotary readiness position.

A disadvantage of this prior art is that the drive rod coupling device, consisting of the driving element and the driving projection arranged displaceably in the folding air form an additional component, which unnecessarily increases the drive rod fitting.

Furthermore, from W02004 / 015232 A1 an anti-burglar alarm for a window or a door with two in a fixed frame immediately next to each other - without fixed center post - built-in wings known, the at least on the Falzumfangsfläche the adjacent spars in a stepped profile one from a cuff rail and a longitudinally displaceably guided guided drive rod existing drive rod fitting included. On the drive rod of the espagnolette movable locking members with locking engagements in and out of locking engagement are adjustable, which sit on the faceplate of the other espagnolette fitting and having a locking device, an adjustment of the drive rod of the overturned passive leaf by interaction of a drive rod located on this security device with one of the drive rod the other espagnolette fitting arranged latch member locks. In this case, the securing part is completely covered in the closed switching position of the locking engagement.

In this prior art, an anti-burglar alarm is ensured by actuating an operating handle of the espagnolette starting from the active leaf.

The invention is based on the object to further develop a generic fitting for a window or a door such that with a backup against burglary in the Espagnolette fitting of the active leaf and thus in the passive leaf of two-leaf windows and doors without mullion to integrate in the frame, the fitting in its manufacture is simple and inexpensive and easier to use in use.

The achievement of the object of the invention is achieved by the features of the characterizing part of claim 1. The subclaims relate to further advantageous embodiments of the invention.

The fitting according to the invention thus has the significant advantage that the locking member of the inactive leaf is securely and immovably encompassed by the ajar attached to the wing in case of ajar to the frame. The espagnolette of the passive leaf can not be manipulated from the outside, in which, for example, the latch member is acted on with the intention to transfer the associated espagnolette fitting from the locking position to an open position and thus to open the wing.

In practice, it has been shown that such burglary attempts are expedient. To remedy the situation, it is necessary to secure the active leaf comparatively complex, for example by further bolt engagements. Due to the claimed arrangement, these can at least partially be eliminated.

Particularly simple and without additional effort, the conventional handling for closing and opening the double-leaf window or door is maintained. During the closing process in which the active leaf is brought from the rotational position coming into an approximately surface-parallel alignment position to the frame, the stationary connected to the espagnolette of the active leaf locking engagement goes with the movable latch member of the espagnolette on the inactive leaf in the locking rod fitting of the inactive position , Here, the inactive leaf is already in his Closed position. An operation of the inactive leaf is no longer possible on the frame resting position of both wings without actuation of the espagnolette fitting on the moving leaf. The embodiment that the locking engagement is not slidably connected via the espagnolette fitting of the active leaf also has an advantageous effect on the mobility of the espagnolette fitting of the active leaf, since frictional resistance of the described safety interlock is not to be expected.

Furthermore, it is particularly advantageous that the locking member consists of a mushroom-shaped pin. With this embodiment, the mushroom head is engaged by the locking engagement complementarily arranged in the closed position, and thus in a Aushebelversuch by the mushroom overhang, which is located in the U-shaped cross section of the locking engagement, a levering prevented.

According to a further feature of the invention it is provided that the locking engagement transversely to the longitudinal direction of the espagnolette fitting has a latch engagement opening. The latch engagement opening is chosen so that the neck of the mushroom-shaped pin is smoothly insertable. The configuration of the latch engagement opening is to be chosen in an advantageous manner so that the greatest possible coverage of the mushroom head is achieved by the locking engagement.

A further preferred embodiment provides that the latch engagement opening has inlet slopes on the respective side surfaces. About the inlet slopes position deviations from the locking engagement to the locking member in a simple manner inexpensive to compensate. With the inlet slopes collisions are prevented, which could be caused by an impact of the locking member to the locking engagement. It is also advantageous that both the locking engagement and the locking member associated therewith is attached to a respective corner drive. This ensures that the interacting components have a defined distance from the wing edges. In the case of an arrangement on another component, which must first be dimensionally adapted to the wing dimensions, this is not possible.

In order to obtain the most optimal protection against burglary, it is particularly advantageous if the locking engagement has a deflection in the region of the locking engagement opening with a distance from the faceplate of the espagnolette fitting and spaced so far that it faces near the opposite espagnolette fitting of the other wing. This prevents a possible intervention in the closed position by unauthorized persons to remove the outer blow bar of the inactive leaf, since the gap between the two espagnolette fittings is too small for possible tool engagement.

An expedient, because simple and inexpensive production of burglar alarm is ensured if the deflection of the locking engagement in cross-section is U-shaped, as already mentioned, the bolt engagement opening is arranged on the side facing away from the espagnolette fitting. Thus, in a simple manner, for example, by punching and molding technique create a cost-favorable variant that forms a completely enclosed space with the simplest means. In addition, the material properties create a very high resistance to a possible burglary attempt.

According to a further special feature of the invention, the locking engagement forms over the Stulpschienenbreite in the direction of wing outside a projection. Also, this feature provides increased resistance in a possible burglary attempt, since the space between the two Espagnolette fittings, ie the Falzraumtiefe is reduced. The burglar is given no opportunity to bring his tool for levering the fitting in use. In addition, the operative connection between the latch member and latch engagement by the extended engagement path increases, which advantageously affects the stability of the burglar alarm.

If the attachment of the locking engagement on the faceplate of the espagnolette fitting by means of a welded joint or a rivet and the supernatant is additionally connected directly to the wing profile by at least one attachment hole for fasteners, this is another criterion for the increased resistance of the burglar alarm.

According to a further feature of the invention it is provided that the locking engagement is made of a stamped part due to its simply developed design, so that also have a positive effect on the cost of the cost of the espagnolette fitting. Furthermore, due to the strength, the material meets the requirements that are set to counteract a possible break-in attempt.

Further advantages emerge from the following description of the drawing.

In the drawings, embodiments of the invention are shown. The drawing, the description and the claims contain numerous features in combination. The person skilled in the art will also consider the features individually and summarize them in meaningful further combinations.

to be installed espagnolette fittings of FIG. 2 and FIG. 3 in a single view in plan view.

In Figure 1 of the drawing is a double-leaf window to see that is designed as a so-called Stulpflügelfenster, in which therefore the first or active leaf 1 and the second or inactive leaf 2 are installed side by side in a frame without the interposition of a fixed center post. As a rule, while the active leaf 1 is in operative connection with the frame via a Drehkippbeschlag, while the inactive leaf 2 is installed as a pure rotary wing in the frame.

In this case, the espagnolette fittings 3 and 4 are mounted at least in the adjacent vertical bars of the active leaf 1 and the inactive leaf 2, in such a way that they oppose each other there on the Falzumfangsfläche, while total or at least with their drive rods 5,6 are received in stepped profile grooves, which are covered by cuff rails 7,8 (Fig. 2 to Fig. 4).

The espagnolette fitting 3 of the active leaf 1 interacts with a locking member 10 fixedly attached to the faceplate 7 with a locking member 10, which is arranged on the faceplate 8 of the espagnolette fitting 4 and is guided and secured longitudinally displaceably on the inactive leaf 2. Since it is in the espagnolette fitting 3 for the active leaf 1 is a Drehkippbeschlag, it consists - as already apparent from Figures 1 to 4 - from a Eckumlenkung 12,13 and not shown tilt lock, which are coupled together by a not shown gear , In this embodiment, the safety lock 11 is arranged on the corner deflections 12,13. But it is also possible, the safety lock 11 on the closure side another or more functional parts of the espagnolette fitting 3.4 to position.

According to FIG. 1, the active leaf 1 and the fixed leaf 2 are in the closed position with the respective drive rod fittings 3 and 4. By removing the outer beater bar of the passive leaf 2, even in the closed position there is a risk that unauthorized persons gain easy access to the interior, since the opening provides so much space that a burglar at the-not here-in the Beschlagaufnahmenut lying in the rebate Stulpflügelhebel arrives in order to turn it in the open position and then to be able to get in, without causing any further noise-intensive destruction.

To now secure the inactive leaf 2 in its closed state against burglary, the on the espagnolette fitting 3 of the tilt and turn, i. of the active leaf 1, fixedly arranged locking engagement 9 by the interaction of the located on the espagnolette 4 locking member 10 in the engaged position and secures the drive rod 6 of the recumbent passive leaf 2 against further adjustment.

According to FIGS. 2 and 3, the espagnolette fitting 3 with the locking engagement 9 is in a position resting on the frame, the locking engagement 9 being in direct contact or in direct proximity with the locking member 10 located on the espagnolette fitting 4. In this case, the locking member 10 is retracted into a locking engagement opening 14 of the locking engagement 9 and prevents the drive rod fitting 4 can be moved.

It is particularly advantageous that the locking member 10 is formed as a mushroom head pin, so that a levering of the safety lock 11 is excluded by a movement perpendicular to the sash. This prevents that in a collapse first the locking member 10 is lifted out of the locking engagement 9 and then moved. by virtue of the mushroom pin design and the U-shaped overlap of the latch engagement 9 are all potential areas to finally move the espagnolette fitting 4 of the passive leaf 2 via the latch engagement 9 in the open position, covered. Both the locking member 10 and the locking engagement 9 are correspondingly secured in a direct engagement with the component by the choice of the material in terms of resistance, in which the locking member 10 is made, for example, as extruded part and the locking engagement 9 is formed as a stamped part.

Only when it is switched by adjusting the espagnolette fitting 3 of the active leaf 1 or tilt-turn window from the closed position to the rotational position corresponding to FIG. 2 and 3, so that all the rest arranged around the espagnolette 3 interlocks are free to rotate ready position, which can be independent of the espagnolette fitting 3 fixed to the faceplate 7 arranged latch engagement 9 by opening the Drehkippflügels in the open position from the locking member 10 of the espagnolette 4 on the passive leaf 2 out, after which the blocking against repositioning of the espagnolette 4 is repealed and the operating handle on the inactive leaf 2 can be operated to open the passive leaf 2 or rotary wing.

However, this also offers the advantage that accidental non-locking of the inactive leaf is avoided, since otherwise the active leaf can not be closed.

The embodiment according to FIGS. 2, 3 and 4 shows a locking engagement 9, which is firmly connected to the faceplate 7 of the espagnolette 4. Furthermore, on the espagnolette fitting 4 opposite side of the locking engagement 9, a locking engagement opening 14 is provided in which, according to Fig. 2 and 3, the locking member 10 is retracted and from the rotational opening position of the active leaf 1 in the resting on the frame position of both wings 1.2 mushroom-like design of the locking member 10 secures the inactive leaf 2 against levering. In this case, the locking engagement 9 on the respective side surfaces 15,16 inlet slopes 17,18, which facilitate the running of the locking member 10 in the locking engagement 9. Particularly with small dimensional deviations of the espagnolette fittings 3, 4, the inlet bevels 17, 18 are important, since they automatically restore equalization in height to the espagnolette fittings 3 and 4 but also to the wings consisting of fixed leaf 2 and active leaf 1.

As a result, however, even slight deviations are compensated, which can be caused by the coupling of the locking member 10 and the locking engagement 9 bearing corner drive on a drive rod drive. On the other hand, the arrangement at the Eckumlenkungen but also a comparatively accurate assignment is ensured relative to the wing or Rahmenfalz.

The locking engagement 9 is U-shaped, as seen in FIGS. 2 and 3, so that a deflection 19 is formed, which forms a distance 20 from the face-plate 7 of the espagnolette 3. The distance 20 is chosen so that it the clearance from the espagnolette fitting 3 to the espagnolette fitting 4 i. the Falzraumtiefe so far as possible limited, that in a possible burglary attempt no tool for levering can be applied. Another advantage results from the fact that the game between the active leaf 1 and 2 wing is reduced to the frame, which also has the consequence that the rigidity of the window or door increases and a levering is difficult.

According to the embodiment according to FIG. 4, it can be seen in the ratchet engagement 9 that it forms a projection 22 beyond the cuff width 21 in the direction of the outside of the wing, that is to say in the direction of the fixed frame of the wing 2. With the projection 22 and at the same time the inlet length of the bolt engagement opening 14 is extended, resulting in a deeper engagement of the locking member 10 results. Furthermore, the strength of the latch engagement 9 is increased.

Again, the space between the two espagnolettes 3,4 is reduced, but in this case in the direction of wing outside. to Falzraumtiefe. With the fixed connection of the locking engagement 9 to the faceplate 7 of the espagnolette fitting 3, for example, by a welded joint or a rivet connection, and the conventional compound of the espagnolette fitting 3 to the active leaf 1 by fastening means z. B. by screws, the locking engagement 9 is already held stationary. The strength is advantageously increased in the area of the safety lock 11 in that fastening holes 23 are provided on the projection 22, according to FIG. 4, which form the direct connection to the moving leaf 1 via fastening means (not shown), for example by screws.

The formation of the locking engagement 9 on the espagnolette fitting 3 also allows easy installation.

The longer latch engagement opening 14, the reduced space towards the wing outside and the additional attachment, individually or in its entirety, a criterion for maximizing burglary security is because the burglar is given no opportunity to bring his tool advantageous to engage and the safety lock 11 from her To move the lock position to an unsecured open position.

Not shown but also conceivable in FIGS. 1 to 4, the arrangement of a plurality of safety interlocks 11 on the functional components of the espagnolette is 3.4.
