Description

The invention relates to a hinged-swing window, in particular a roof window with a hinged and hinged wing against a frame, with a trained in a closed position for locking the wing in the frame espagnolette, with a hinged on a hinged storage on the frame folding frame, with an oscillating bearing hinging the wing to the folding frame and with a handle for driving the drive rod fitting.

Such folding in a folding position and in a swinging position movable swing-swing window is often arranged in a roof surface and is for example from the DE 31 21 322 C2 known. In this hinged-swing window, the movement of the wing is in the folded position by a hinged on the hinged frame and actuated by gravity flap engages behind a hinged pin attached to the wing. In the swinging position of the axle journal slides along a guide rail, so that the folding frame is also pivoted with. This allows the outside of the wing in the swinging position to be cleaned from the inside. A disadvantage of this hinged-swing window, however, is that the movement of the wing in the swinging position is very difficult, since the axle journal slide over the guide rail and also the snap frame must be raised. In the closed position, the handle engages by means of a tongue in a frame-side closing piece.

Furthermore, such a hinged-swing window of the DE 197 17 351 A1 known. In this hinged-swing window, the handle is designed as arranged on a lower horizontal bar of the wing handle. Between the wing and the frame, a wing frame completely enclosing the frame is arranged, which is mounted in the middle with the wing and at its end facing away from the handle bar with the frame. The storage of the connection frame with the wing forms the swing bearing, while the storage of the connection frame with the frame forms the folding storage. The locking of the wing in the frame in the closed position via the connecting frame, but this has a high structural complexity result.

The invention is based on the problem, a hinged-swing window of the type mentioned in such a way that it provides a high resistance to a Aufbruchtruch in located in the closed position wing and that it is particularly comfortable to use.

This problem is inventively solved in that the espagnolette fitting has a first, the wing in a folded position in the snap frame locking closure and a second, the wing in the closed position directly in the frame locking closure and that the handle rotates about a designated angular range in the Wings is mounted and is coupled via an opposing gear with two counter-movable drive rods, wherein the drive rods are each coupled to a first and a second closure.

By this design, the two offer directly acting between the frame and the wing second seals in the closed position, a high level of protection against a break-open attempt of the hinged-swing window according to the invention. In the swinging position, the wing can be freely swiveled independently of any movement of the snap-in frame and can therefore be easily cleaned. In the folded position, the first closure ensures that the wing is reliably connected to the folding frame and therefore can only be folded together with the folding frame. Since the control of the closures is done completely on the espagnolette fitting, the operation of the folding-swing window invention designed particularly comfortable. The oppositely driven via the counter-rotating gear drive rods also allow the use of many identical parts, resulting in a particularly cost-effective production of folding-swing window according to the invention. Preferably, the first closure locks the wing in the closed position with the snap frame.

The folding-swing window according to the invention has a particularly high security against a violent opening attempt when at least one of the closures has a drivable by the drive rod pivot bolt.

The folding-swing window according to the invention allows ventilation at a high burglary security, when in a gap ventilation position of the espagnolette fitting, the second closure has a second, the wing at a designated distance to the frame halterde closure position. As a result, the wing is pivoted together with the folding frame to the folding storage in the night ventilation position and locked by the second closure with the frame.

The operation of the folding-swing window according to the invention is particularly comfortable when the switching stages of the espagnolette fitting in the order closing position - gap ventilation position - folding position - swinging position are arranged. As a result, the frequently actuated positions closed position, slit ventilation position and folding position by a slight rotation of the handle can be controlled, while usually only required for cleaning swing position requires a large rotation of the handle and therefore can not be controlled by mistake.

To further increase the comfort in the operation of the hinged-swing window according to the invention, it contributes, if the maximum rotation angle of the handle over an angular range of less than 180 °, preferably over 150 ° - 160 ° extends, wherein in the closed position, a handle part the handle is arranged parallel to a spar of the wing. Furthermore, this avoids the risk of pinching the hand during the movement of the blade in the usually serving as a cleaning position swing position.

To further increase the stability of the hinged-swing window according to the invention, it contributes, when the folding frame surrounds the wing on the side facing away from the handle U-shaped.

The wing is reliably held in the set folding position when a biased by a spring element and / or held by a brake support is hinged to the frame and the folding frame. At the same time, the wing is freely rotatable in the swinging position often used for cleaning purposes.

According to another advantageous development of the invention, the second closure is structurally particularly simple if the second closure has a locking frame fastened to the frame with two recesses arranged one above the other and if the locking bolt engages in the closed recess in the closed position and in the gap ventilation position in the closed position the frame far recess penetrates.

The introduction of the pivot bolt in the frame of the distal recess of the locking block is particularly comfortable according to another advantageous embodiment of the invention, when the frame remote recess and the pivot bolt facing each other ramps. This makes it particularly easy to find the ventilation position.

A pushing back of the pivot bolt from a pivoted position without movement of the drive rod can be easily avoided according to another advantageous embodiment of the invention, when the second closure has a blocking element coupled to the drive rod and when the blocking element in the closed position or gap ventilation position engages behind a projection of the pivot bolt , By this design, the second closure is self-locking, which contributes to further increase the burglar resistance of the folding-swing window according to the invention.

The structural complexity of the self-locking design of the second closure can be kept particularly low according to another advantageous embodiment of the invention, when the blocking element is made in one piece with the drive rod and the projection part of a drive of the pivot bolt with a toothing of the Drive rod meshing teeth of the pivot bolt is.

A fitting groove of the wing can be kept particularly small according to another advantageous embodiment of the invention, when a housing of the pivot bolt projects beyond the wing. By this design, the pivot bolt may also have particularly large dimensions.

To simplify the assembly of the folding-swing window according to the invention, it is beneficial if the pivot bolt and a corner drive have a common housing.

To further increase the security against breakage of the hinged-swing window according to the invention, it contributes, if the accessibility of a screw of the locking block or the mobility of a screw covering the protective cover is blocked by the located in the night ventilation position and in the closed position wings. By this design, the locking frame can be removed only when the wing is in the folded position or in the swinging position. As a result, the screw can also be arranged such that it is particularly easy to access during assembly of the folding-swing window according to the invention.

The espagnolette fitting can be adjusted according to another advantageous embodiment of the invention between the folding position and the swinging position without entrainment of the pivoting bolt when the coupling of the drive rod with the second closure has a backlash in which the drive rod is movable without entrainment of the pivoting bolt. This contributes to limiting the range of movement of the pivot bolt.

The locking of the wing in the snap frame designed in accordance with another advantageous embodiment of the invention structurally particularly simple if the first, the wing in the snap-lock locking a arranged in a corner of the folding frame corner bracket and coupled to the drive rod, in folding position in a Recess of the Eckbocks penetrating spatula has. Preferably, the end of the drive rod is formed as a spatula.

Figure 1 shows a hinged-swing window, which is often used as a roof window, with a frame 1 and a wing 2. The wing 2 is connected via a snap frame 3 with the frame 1 and has an espagnolette 4 shown in Figure 2 Locking of the wing 2 in the frame 1. The folding frame 3 is articulated via a hinged storage 5 with a horizontal folding axis 6 on the frame 1 and a swing bearing 7 with a horizontal horizontal axis of oscillation 8 on the wing 2. The espagnolette fitting 4 has two first closures 9 for locking the wing 2 in the folding frame 3 and two second closures 10 for locking the wing 2 in the frame 1. The espagnolette fitting 4 has two drive rods 13 driven by a rotatable handle 11 via an opposing gear 12 to control the closures 9, 10. A fault-prevention 14 with a arranged on the espagnolette 4, a frame-fixed counterpart 15 opposite button 16 prevents the espagnolette fitting 4 can be adjusted when the wing 2 was pivoted about the folding axis 6 or the swing axle 8.

In the illustrated closed position, the wing 2 abuts against a stop 17 of a corner bracket 18 fastened to the folding frame 3 and is locked by means of the second locks 10 in closing blocks 19 fastened to the frame 1. The first closures 9 connect the wing 2 with the folding frame 3. By a movement exclusively of the second closures 10 in the open position, the wing 2 can fold with the folding frame 3 to the folding axis 6 in a folding position. The movement of the wing 2 is braked by a hinged to the frame 1 and the folding frame 3 support 20. If both shutters 9, 10 are moved into the open position, the folding frame 3 is due to gravity on the frame 1, and the wing 2 can be rotated about the swing axis 8 in a swinging position.

As Figure 3 shows, the second closures 10 each have a cooperating with the locking block 19 pivot bolt 21. The pivot bolt 21 penetrates into a frame 1 near recess 22 and thus holds the wing 2 shown in Figure 1 in the voltage applied to the frame 1 closed position. If the pivot bolt 21 is moved by a corresponding drive of the drive rod fitting 4 shown in Figure 2 in the frame 1 remote recess 23 of the closing bracket 19, the wing 2 is at a small distance to the Frame 1 held. This characterizes the night ventilation position of the hinged swing window. In order to easily find the frame 1 remote recess 23, the locking block 19 and the pivot bolt 21 facing each other ramps 24, 25. The locking block 19 is in the assembled state connected by a screwed into the frame 1 screw 26. The screw 26 is covered by means of a trained as a sheet metal protective shield 27. The protective cover 27 is inserted in a slot 28 of the closing block 19. The slot 28 of the closing block 19 is covered by the wing 2 located in the closed position or gap ventilation position of FIG. This allows the screw 26 solve only in the swinging position or the folding position of the wing 2.

FIG. 4 shows the second closure 10 from FIG. 3 in a view from below with adjoining regions of the wing 2. Here it can be seen that the pivot bar 21 and a corner deflection 29 of the espagnolette fitting 4 have a common housing 30. The housing 30 has a groove 31 for guiding a arranged at a 90 ° angle to each other straight portions 32, 33 of the drive rod 13 connecting spring 34. Furthermore, the housing 30 of the pivot bolt 21 is above a the outer boundary of the wing 2 forming cuff rail 35 before. A fitting groove 36 of the wing 2 requires thereby only a small depth. The drive rod 13 has a bend 37 in the region of the pivot bolt 21 and a toothing 38, which cooperates with a toothing 39 of the wing 2. For clarity, Figure 5 shows the second closure 10 of Figure 4 in the night ventilation position, in which the pivot bolt 21 is pivoted in the frame 1 remote recess 23 of the closing bracket 19.

Figure 6 shows greatly enlarged the pivot bolt 21 of the second closure 10 with adjacent areas of the drive rod 13. The teeth 38 of the drive rod 13 is in engagement with the teeth 39 of the pivot bolt 21, wherein the pivot bolt 21 in the out of the housing 30 out tilted position is shown. A designed as part of the teeth 38 of the drive rod 13 blocking element 40 is in the range of movement of a formed as part of the teeth 39 of the pivot bolt 21 projection 41. Thus, the pivot bolt 21 without prior movement of the drive rod 13 does not push back into the housing 30. In a drive of the drive rod 13, however, the teeth 38, 39 of the drive rod 13 and the pivot bar 21 cooperate such that the pivot bolt 21 is pivoted back into the housing 30. At the teeth 38 of the drive rod 13 is adjacent to a slot of the drive rod 13 trained backlash 42 at. When the teeth 39 of the pivot bolt 21 penetrate into the backward passage 42, the pivot bolt 21 is located within the housing 30. Subsequently, the drive rod 13 can be displaced without the pivot bolt 21 being further pivoted.

When the toothing 39 of the pivoting bolt 21 is located in the backward passage 42, only the first shutter 9 shown in FIG. 7 is activated. The first closure 9 has a recess 43 arranged in the corner frame 18 arranged on the folding frame 3 for receiving a spatula 44. The spatula 44 is formed as a free end of the drive rod 13 shown in Figure 2 and penetrates in the position shown in the recess 43 a. For a movement of the wing 2 is blocked relative to the folding frame 3. Furthermore, Figure 7 shows that the corner bracket 18 is positively held in a corner of the folding frame 3 and has ramps 45 for the wing 2.
