Description

The invention relates to a window fitting for a window a window frame, a sash that gela on the frame gert and in an opening direction from a closed to egg ner open position is pivotable, with a sash on the casement operating rod cooperating with a bolt and on the blen Drah a locking plate are attached, by means of which the ge closed sash frame can be locked on the frame. Further The invention relates to a window with such a window blow.

A window generally has a casement, which means Fitting on a frame pivoted or tilted is. There are usually locking elements on the casement (especially Rol lenbolzen) attached to the fittings and in Locking plates on the frame are slidable. The locking elements are arranged in the area of a fold between the blend frame and the closed casement is formed.

The frame and the sash are subject to the Her position-related dimensional fluctuations. Furthermore warp and win which they are subject to during use, thermal stresses and the weight of the glazing act on them. The fold between Frame and casement is therefore also used to compensate for Dimensional fluctuations and delay.

It is an essential feature of a window that it is in a attempted break-in offers sufficient security. Because burglars often shy away from making noise and the window pane smashed, try the window on the window frame or window break up gel frame. Here, a burglar, for example by means of a crowbar or a screwdriver, from  on the outside between the frame and sash and lever the Casement inside. According to the quality assurance according to DIN V In 18054, a RAL-RG 607/3 quality mark for the fittings is used If the window tries to pry out with a lever torque of Resist 200 Nm or 300 Nm. Conventional locking elements one Windows are not enough to withstand these forces.

It is known, in addition to locking elements on the casement Arrange locking elements to ensure security against burglary increase. The locking elements are in the corresponding locking plates on Frame can be pushed or swiveled. The profile parts of the Blen Drahmens and the casement are each for aesthetic reasons but lean and at the same time have sufficient sta to provide a high level of heat and sound insulation to be able to wear glazing. The place to arrange such additional Licher locking elements is therefore very limited.

With a security package from Unilux called "Safe-II" are on a locking mechanism next to roller bolts additional mushroom cones attached. The roller bolts lock it Windows, while the mushroom cones also lock. The Rol Lenbolts and mushroom cones are each in a corner of the window pla graces and can by an actuating rod of the lock mechanism parallel to the profile parts of the casement ver be pushed. The roller bolts are each in one bolt sheet metal pushed. The roller bolts push the sash to Frame to increase heat and sound insulation, and ver lock the casement in this closed position. At the same time, the mushroom cones are shot into a cone plate ben in which her mushroom-shaped head hooks and additionally locked.

Door locks are known from the company Gretsch-Unitas GmbH, where locking hooks or locking bolts as locking elements on Engage the door leaf in the corresponding striking plates on the door frame. The door locks are relatively large and therefore the restricted space of a window unsuitable.

The invention has for its object a window fitting and to provide a window with such a window fitting,  where the window fitting even in very cramped space conditions on the casement an increased security against Ein break offers.

Show on the casement due to the limited space known mushroom cones, such as. B. that of the security package of the Fir ma Unilux, slight play on the associated pivot plate. At Windows that are not ideal manufacturing dimensions or ge are slightly warped, the locking mechanism or canted jammed and the mushroom cone grinds on the cone plate. The fen ster can no longer be locked easily. This problem has been able to use a standard sash lifter cannot be completely cleared out.

When it comes to door locks from Gretsch-Unitas GmbH, the one the locking hook and locking bolt reached into the striking plates almost free of play. Furthermore, the locking pin and locking pin fen smooth surfaces. Doors point in relation to windows a higher closing force, so that the Rie gel elements does not cause problems. Such would be the case with windows However, door locks cannot be used, it would be the above written problem exist.

The invention also aims to provide a window fitting and to provide a window with such a window fitting at which the window fitting even with a not dimensionally accurate posed or warped windows easily lockable and is lockable and at the same time sufficient or increased Offers security against burglary.

The task is according to the invention with a window fitting solved the features mentioned in claim 1. The bolt is from a profile part of the casement in the vertical direction a profile part of the frame can be pushed. Furthermore, in the Rie gel itself formed the cam track. The bolt is also in locking area designed so wide that it is considerably wide ter than known bars. The bolt therefore engages one wide area in the frame and offers an increased Protection against burglary.  

According to the invention, the task is also through a window fitting be solved with the features mentioned in claim 2. The Rie gel is also in from a profile part of the casement perpendicular to a profile part of the frame slidable. The cam track is on an operating rod formed a locking mechanism. The bolt is in the process of sliding direction considerably shorter than known bolts (door locks by Gretsch-Unitas GmbH). Nevertheless, the Tie sufficient security against burglary, since he is on the cure venbahn is held.

Furthermore, the object of the invention is by a fixed fitting solved, in which the locked bolt in the opening direction from Bolt plate a distance of 20% or more of the thickness of the bar gels in this area. The invention is based on the basic idea that the bolt only in the opening direction of the Casement, but not opposite to this opening direction security against burglary. Therefore, the ver did not lock bars in the opposite direction; the opening direction on Fit the locking plate or hook it behind. The bar can do so be formed that he ver the entire opening utilizable space and to the transom in one considerable larger distance is arranged than known bars.

The risk of the locking mechanism getting caught or jammed is significantly reduced. At the same time, both the Bolts and the stop made of stronger material be, so that the window fitting higher security against on break offers.

This window fitting according to the invention also offers at beson low space requirement a particularly high level of security, if he additionally like the window fittings according to claim 1 or 2 is designed.

By the bolt and the locking plate each at least one tooth and the teeth come into engagement when the closed ne and locked casement a bit in the opening direction is moved, the sash is also perpendicular to its opening direction in the event of a break-in. Because the bolt  and the locking plate can be made from relatively strong material are and can have a relatively large width, meh rere teeth are formed, which is a significantly enlarged Si offer security against burglary.

When the bolt is facing out next to the actuation bar is arranged on the casement, it reaches into the opening direction in the middle of the frame. At acquaintances The latch is always on the operating rod attached and engages only on the edge of the frame. This he inventive arrangement of the bolt therefore has a higher Stability on.

Another possibility to break into a window is in that the burglar from the outside, e.g. B. by means of a screw benziehers, moved a locking pin of the locking mechanism, and this opens the locking mechanism. Who can prevent this by placing the latches advantageously on the outside next to each Locking pins are arranged. The locking pins are then from the outside not accessible or movable.

The locking mechanism can be made with very few components Lich similarly known locking mechanisms can be designed by the latch in the opening direction in the middle area of the actuator supply rod is arranged. The latch can be used in such Case with curves penetrating it in the opening direction be formed in a bolt on both sides the operating rod is supported. The bar is then special secured against pulling out.

To prevent the bolt from being tilted when sliding on or in the sash To prevent the frame, the latch can be advantageous in a row Gelbag be guided with a guide groove. The bolt pocket can also be attached to the sash frame at its base, to provide high stability on the casement.

An advantageous way to prevent the bolt from being pulled out Securing the sash consists of two sows on the transom ze are formed opposite one part of the Grab the bolt pocket. The latch can then not be fully removed  the lock pocket.

The bolt in the sliding direction by a spring is advantageous, such as B. a leaf spring or coil spring biased. The Latch is especially protected against being misjudged additionally secured in the locked state.

The window fitting can be advantageous for a tiltable window be designed so that the actuating rod is linear between three points, a blocking point, an open point and a tipping point is movable. The cam track is designed so that it from Lock point to the open point to the actuation path of the actuators supply rod or inclined to the profile part of the casement ascending curve section and then one to the tipping point has parallel curve section. Such a bar is only locked at the blocking point and can therefore be in the upper area of the tilting window attached.

Another advantageous variant for a window fitting egg nes tiltable windows, is a bolt in which the curved track from the blocking point to the open point one to the profile part of the wing frame inclined rising and then to the tipping point has a sloping curve section. The bolt is then locked at the blocking point and at the tipping point and can therefore in lower area of the tilting window.

The window fitting according to the invention is particularly advantageous used in a window that has slim profile parts and therefore only take up a fitting with a small footprint can.

Fig. 12 shows a second embodiment of the locking plate shown in Fig. 9 in a bottom view.

Referring to FIGS. 1 to 4 is a first exporting approximate shape of the window fitting shown. A window 10 shown in cross section comprises a profile part of a frame 12 and an adjacent profile part of a casement 14 , which are each made of wood. On the sash 14 , a glass sheet 16 between two seals 18 and 20 is summarized GE. The seal 20 is held by an aluminum profile 22 which is attached to the casement 14 . An aluminum profile 23 is also attached to the frame 12 . The aluminum profiles 22 and 23 together with the wooden casement 14 and frame 12 form a window in a composite construction.

The window 10 is shown in Fig. 1 in the closed position Darge, here the closed position means the position of the sash 14 to the frame 12 , in which cher the sash 14 and the frame correspond to the ideal position dimensions Her, the sash 14 on the frame 12 is present and is not exposed to tensions that distort it from the ideal position. The sash 14 is pivotally mounted on the frame 12 by fishing (not shown) and can be opened in an opening direction illustrated by an arrow X. In the closed position, the opening direction X extends perpendicular to a main plane or disk plane of the wing frame 14 .

In general, the aluminum profiles 22 and 23 are attached to the outside of the sash 14 or frame 12 and the wing frame 14 is on the inside of the frame, ie it can be opened in the opening direction X inwards. An arranged on the sash 14 and to the frame 12 sealing seal 24 compensates for manufacturing tolerances and warpage that the sash frame 14 has in the opening direction X with respect to the frame 12 . The seal 24 thereby prevents air flow between outside and inside.

Between the frame 12 and the sash 14 is a cross-sectionally rectangular fold 26 is formed, in which Sperrele elements (z. B. roller bolts) (not shown) can be arranged. The fold 26 has a fold width b in the opening direction X and a fold height h in a direction Z perpendicular thereto. The fold 26 also serves to compensate for manufacturing tolerances and warpage and to introduce fittings in the Z direction.

In a groove 28 open to the fold 26 in the casement 14 , a locking mechanism with an actuating rod 30 and a cover 32 is attached. The actuating rod 30 is relative to the casement 14 and the cover 32 perpendicular to the direction spanned by the direction Z and the opening direction X plane and thus parallel to the profile part of the casement 14 shown ver (ie perpendicular to the plane of the drawing of FIG. 1). On the actuating rod 30 , the locking element, for example a roller pin known per se (not shown), is introduced. When moving the operating rod 30 , the locking element engages in a locking plate (not shown) on the frame 12 , blocks the sash 19 and urges it to the frame 12th The seal 24 thereby seals the window 10 .

To secure against breaking open in the opening direction X, a bolt 34 is formed in addition to the locking mechanism, which interacts with the actuating rod 30 together in the embodiment shown. The function of this bolt 34 is illustrated in detail in FIGS. 2 to 4. The bolt is guided as a push belt 34 in a locking pocket 36 . The locking pocket is inserted into a recess of the sash 14 which is open to the fold 26 . A stop in the form of a locking plate 38 is arranged on the frame 12 opposite the sliding bolt 34 . The locking plate 38 is fixed by screws 42 in a recess of the Blen frame 12 .

In a side wall of the locking pocket 36 , an elongated hole 46 is formed parallel to the actuation rod 30 . A bolt 40 extends through the elongated hole 46 and is attached to the actuating rod 30 BEFE Stigt. The bolt 40 can be displaced by an actuation path Y in the elongated hole 46 by means of the actuation rod 30 from a blocking point S via an open point O to a tilting point K. The sash 14 is locked at the locking point S in the closed position. The sash 14 can be opened at the open point O and tilted at the tilt point K.

In FIGS. 2 and 3, 5 and 6 as well as 8 and 9 it is illustrated that a cam track is other than 44 in the sliding bolt 34, which passes through the sliding bolt 34 in the direction X and extends along the Y betae tigungsweg. The bolt 40 engages in this curved track 44 . When the actuating rod 30 is moved along the actuation path Y, the bolt 40 moves in the curved path 44 and displaces the slide bolt 34 in the bolt pocket 36 . In this way, the linear movement of the actuating rod 30 is implemented paral lel to a profile part of the casement 14 in a perpendicular movement of the push bolt 34 perpendicular thereto.

The principle of the conversion of movement from horizontal to vertical can also be realized in that the cam track on the actuating rod and the engaging part, such as. B. the bolt 40 is formed on the slide bolt 34 .

On the slide bolt 34 is formed at the center thereof in the guide web 54 which extends in the sliding direction and is guided in a guide groove 52 . The slide bolt 34 is thereby secured against tilting or jamming when moving.

The slide bolt 34 has a width "r" at its end directed in the Z direction, with which it engages behind the locking plate 38 . The bolt width "r" is chosen so that it is larger than the actuation path Y of the actuating rod 30 , so that the cam track 44 through which the pin 40 moves over the actuation path Y, can be formed in total in the slide bolt 34 . The bolt width "r" is considerably wider than with known bolts for windows and also wider than with known bolts for doors. The slide bolt 34 is therefore particularly resistant to burglary.

Since the entire actuation path Y of the actuation rod 30 is used by the cam track, the cam track 44 can be flat, so that the slide bolt 34 is very smooth. Due to the good guidance and smooth operation of the sliding lever 34 , its length "l" in the shooting direction can be very small without the bolt tilted when moving. The length "l" of the slide bolt 34 is at most twice as large as its sliding path "w". This is particularly advantageous because the casement of windows is very slim.

The cam 44 of the slide bolt 34 shown in FIGS . 2 and 3 has in the direction Z a to the profile part of the wing frame 14 parallel and then a sloping section from. When the actuating rod 30 is displaced along the actuating path Y, the bolt 40 leaves the slide bolt 34 in the Riegelta cal 36 along the parallel section of the curved path 44 . Along the sloping section of the curved track 44 , the pin 40 pushes the slide bolt 34 out of the locking pocket 36 . When the direction of actuation is reversed, the push bolt 34 moves in the opposite direction. This type of cam track is suitable for a bolt which is arranged on a tiltable window in the upper, tilted area of the window. Such a latch is only locked when the window is closed.

The cam track 44 of the slide bolt 34 shown in FIGS . 5 and 6 has a to the profile part of the casement 14 to rising and then a falling section, ie the rising and falling sections of the cam track are at an acute angle to the actuation path Y. Move ben the actuating rod 30 along the actuating path Y from the blocking point 5 to the open point O, the bolt 40 guides the slide bolt 34 in the bolt pocket 36 along the sloping portion of the curved path 44 . Along the ascending section of the Kur venbahn 44 from the open point O to the tilt point K, the bolt 40 pushes the slide bolt 34 out of the bolt pocket 36 . When the direction of actuation is reversed, the push bolt 34 moves in the opposite direction. This type of cam track is suitable for a bolt which is arranged on a tiltable window in the lower, non-tilted area of the window. Such a bolt is locked when the window is closed or tilted.

In the window fittings shown in FIGS. 1 to 6, the slide bolt 34 is directed outward next to the actuating mechanism, that is to say arranged next to the actuating rod 30 . The bolt 40 protrudes from the actuating rod 30 in the cam track 44 , which does not fully penetrate the slide bolt 34 in the opening direction X dig. The cam track 44 forms a recess in the slide bolt 34 in this embodiment. The bolt 44 can have a slide ring and the slide bolt 34 can be pretensioned against the direction Z by a spring. The slide bolt can also be formed in this embodiment next to a locking element of the locking mechanism, so that the locking element is not accessible from the outside. As can be seen in Fig. 1, the screw 42 is arranged far to the central region of the frame 12 and can therefore absorb high forces.

In Fig. 7 a locking bar plate 38 is shown, which is integrally formed with a locking edge 56. The locking plate 56 is, as in conventional window fittings, suitable for receiving a locking element, such as a rolling pin. The locking plate 38 has an elongated opening 62 into which the sliding bolt 34 can engage. The locking plate 38 is fastened by screws 42 to the frame 12 and additionally by screws 58 and 60 , which are arranged as in a piece formed as a locking plate.

In the window fitting shown in FIGS. 8 to 10, the slide bolt 34 is arranged in the central region of the actuating rod 30 . The slide bolt 34 can thereby be integrated in the actuation mechanism. The bolt 40 passes through the slide bolt 34 and is fastened on both sides of the slide bolt 34 to the actuating rod 32 . The cam 44 of the Schubrie gel 34 is thereby evenly stressed. In addition, the slide bolt 34 is held in the bolt pocket 36 in a particularly stable manner by the bolt 40 . The bolt can also have one or two opposite approaches, the hook in the Riegelta cal 36 and prevent complete withdrawal of the locking gel from the locking pocket.

A locking plate 38 is shown in FIG. 11, in which the screws 42 are arranged on the outside next to the opening 62 for receiving the slide bolt 34 . The screws 42 are thus screwed into the central region of the frame 12 and have a particularly high stability in the frame 12 . The locking plate 38 shown in FIG. 12 is formed in one piece with a locking plate 56 . The locking plate 38 and the locking plate 56 are fastened to the frame 12 by screws 42 , which are arranged like a locking plate designed as an individual part.

As illustrated in FIGS . 4 and 10, the slide bolt 34 is in its locked position from the locking plate 38 in the opening direction X a distance "a" apart. Based on the thickness "d" of the locking part of the shoe bar 34 , the stand "a" is 20% to 80%. In a further preferred embodiment, the distance "a" is 30% to 70%. Based on the fold width "b", the distance "a" is 5% to 30% or 8% to 25%. A distance "a" between 40% and 50% of the thickness "d" of the sliding bolt 34 is particularly preferred, since this allows manufacturing tolerances and warpage of the sash 14 to be compensated particularly well.

The locking element also has a frame "c" to the frame 14 or the Rie gel pocket 38 against the direction Z. The distance "c" is 5% to 40% of the fold height "h". Distances "c" between 15% and 40% are also preferred, and particularly preferably between 25% and 40%.

On the side surface of the push bolt 34 facing the opening direction X, a tooth 48 is formed, to which an associated tooth 50 is formed from the side surface of the locking pocket 38 . The tooth 48 engages in the tooth 50 when the wing frame 14 is moved in the opening direction X by the distance "a". The sash 14 can also be moved to a certain extent "dz" in the Z direction. Such movement of the sash 14 occurs when an attempt is made to move or open the sash 14 with respect to the frame 12 by the action of force from the outside. The interlocking teeth 48 and 50 prevent further movement of the wing frame 14 in the opening direction X and in the direction Z by friction or positive locking.
