Abstract

The swing window has a drive rod fitting (3), to allow a swing movement into the open position to give a ventilation gap between the window frame (1) and the window pane (2). A handle (13) sets the window mechanism to be open or closed manually or by shifting the drive rod. Locking studs (10,10',14,41) at the window pane engage structured openings (11,11') at the window frame.

Description

The invention relates to a window in which a wing is rotatable relative to a frame about an axis of rotation and tiltable about a tilt axis, with a espagnolette, arranged on a displaceable in several positions drive rod locking pin and the locking pin opposite striking plates for selectively locking or releasing the Wing relative to the frame, with a to be arranged at the intersection of the axis of rotation and the tilting pivot bearing, to be arranged in the axis of rotation scissors bearing, being locked in a locking position of the wing relative to the frame, rotatable in a rotational position of the wings relative to the frame and in a tilted position the wing is tiltable about the tilting axis, and with a night ventilation position in which the wing is slightly away from the frame relative to the locking position.

Windows with such espagnolette fittings are used to allow for a so-called turn-tilt fitting a fourth position of the espagnolette fitting, in which a circumferential ventilation gap between the wing and the frame is generated. The ventilation gap should be sufficient to ensure sufficient ventilation in a room over a long period of time, but also to prevent the room from cooling down. In addition, the wing should withstand wind forces in the night ventilation position. Of course, the window can also be a French window or the like.

An espagnolette for such a window is known for example from DE 30 41 399 C3. In this espagnolette fitting, the drive rod is moved by a movable in four positions handle. The handle can be rotated by a total of 180 °, wherein the espagnolette fitting is in an end position of the handle in the locking position and in the other end position in the tilted position. In the middle position of the handle, the espagnolette fitting is in the rotational position. The gap ventilation position is arranged between the tilted position and the rotational position. For this purpose, fixing means are arranged on the frame, in which a groove for guiding the lock pin is arranged. To bring the window in the night ventilation position, the wing is pressed by the rotational position or the tilted position against the frame and moves the handle in the night ventilation position. Subsequently, the wing is spaced a distance from the frame at least in areas remote from the corner bearing. A disadvantage of this espagnolette fitting is that the locking pin are in the night ventilation position outside the strike plates and thus in this position, the window is not reliably secured against a break-up attempt.

From DE 30 43 926 A1 a window has become known in which the strike plates on the vertical axis opposite the spar in the tilted position have an angled guide. If the strike plates are moved into the angled guide, the wing is at this spar a gap from the frame. Thus, the espagnolette fitting only three positions, namely the closed position, the rotational position and a gap rotational position. The generation of a tilted position, in which the wing is tilted away from the frame by more than a slight gap is not possible with this window.

The invention is based on the problem of designing a window of the aforementioned type so that it has the four mentioned switch positions of the espagnolette fitting and in the night ventilation position provides a similar level of security against a break-up attempt as a window in the closed position.

This problem is inventively solved in that the strike plates have in one of its end positions of the locking pin two transversely to the direction of movement of the drive rod spaced receptacles for the locking pin and that the locking pin is movable into either one or the other receptacle and that a bearing control for moving the locking pin as a function of a switching sequence of the drive rod is optionally formed in the one receptacle or the other recording of the strike plates.

Due to this design, the drive rod requires only three positions to be approached for four positions of the espagnolette, since the gap ventilation position is achieved by the switching sequence of the drive rod and / or manually applied to the wing forces. In the night ventilation position, the locking pins are reliably held in the respective striking plates. Thus, the window according to the invention provides a high level of protection against a break-up attempt in wing located in the night ventilation position. Assuming a fixed range of movement of the drive rod is a further advantage of this design is that the espagnolette fitting at three approaches to the Drive rod can have greater tolerances than four positions of the drive rod. The recordings can be arranged together in a large recess, or the strike plate can have two juxtaposed recesses. Two juxtaposed recesses have the advantage that acting on the wing wind forces can be intercepted in the night ventilation position.

A particularly high security of the window according to the invention against a violent opening in night ventilation position can be easily achieved if the end position in which the strike plate has the two receptacles, the corresponding position of the locking pin corresponds to the closed position of the locking pin.

The operation of the espagnolette has according to another advantageous embodiment of the invention, a particularly high level of comfort when the strike plate has a guide for the locking pin either in the one or in the other recording. By this design can be achieved that during normal operation, a predetermined position, for example, the night ventilation position, the espagnolette fitting and only with an additional pulling or pressing the wing, the alternative position, for example, the closed position is achieved.

The choice of the night ventilation position requires according to another advantageous embodiment of the invention, a particularly low structural complexity when the wing between the gap ventilation position and the next position of the locking pin is perpendicular to its plane manually movable. This movement of the wing is done by pulling or pushing perpendicular to its plane.

The definition of a switching sequence of the espagnolette for achieving the night ventilation position or the alternative position, for example, the closed position, according to another advantageous embodiment of the invention requires a particularly low structural complexity when the bearing control has a pivotable rocker. This makes it possible that the rocker feeds the locking pin in response to the sequence of motions of the drive rod of a recording or the other recording.

To further reduce the structural complexity in the generation of the switching sequence for controlling the gap ventilation position, it contributes according to another advantageous embodiment of the invention, when an axis of rotation of the rocker between the end positions of the locking pin is arranged and the rocker at least one ramp for guiding the locking pin of a has the end positions in the middle position. This ensures that the locking pin is reliably guided both by the gap ventilation position and by the alternative position, for example the closed position, into the next position, as a rule the rotational position.

The leadership of the wing perpendicular to its plane to the frame to or from this can be generated without effort on the wing only by the switching sequence of the drive rod when the rocker of one of the strike plates has two arranged on both sides of the axes of rotation, substantially symmetrical ramps ,

The window according to the invention can be operated comfortably and still produce cost-effectively, when the rocker with two arranged substantially symmetrically to each other Ramps is arranged on the Ausstellschere. A cost-intensive equipment of all locking plates with the two substantially symmetrically arranged ramps having rocker can be avoided, since in the region of the handle, the wing can be easily pulled or pressed.

Malfunction of the espagnolette fitting can be easily avoided according to another advantageous embodiment of the invention, when the rocker is biased to a basic position.

In the known windows, the corner bearing is firmly anchored in the frame. Therefore, no constant circumferential ventilation gap between the wing and the frame can be generated, which leads to an impairment of the air circulation of the window having space and to a visual impairment of the located in the gap ventilation position wing. A uniformly circumferential ventilation gap between the wing and the frame can be produced according to another advantageous development of the invention, when the corner bearing is displaceable perpendicular to the plane formed by the horizontal axis and the vertical axis of the wing. This design makes it possible to offset the wing in the gap ventilation position substantially parallel to the closed position, wherein the corner bearing is moved.

The Ecklager can move according to another advantageous embodiment of the invention on the switching sequence of the espagnolette fitting when the bearing control is located near the corner bearing and a straight first guide of the locking pins located in the end positions and a relation to the first guide staggered second guide between the middle Position and the gap ventilation position of the lock pin has.

The control of the corner bearing requires a particularly low structural complexity when the guides of two mutually biased rockers (45, 46) are separated.

To reduce the manufacturing costs of the window according to the invention, it is beneficial if the bearing control of the corner bearing (7) and one of the strike plates form a structural unit.

The support of wind forces in the night ventilation position requires according to another advantageous development of a particularly low design effort when the strike plate between the two receptacles for the locking pin has a web. It is sufficient that, in the case of a plurality of striking plates arranged distributed over the frame, only a part of the striking plates have the web and the remaining striking plates have a large recess for receiving the locking pegs in the night ventilation position and the other position.

The strike plate can according to another advantageous embodiment of the invention in the closed position and in the gap ventilation position to support forces of the lock pin when the lock pin has an elongated cross-section and is aligned pointing with its narrow side in the direction of movement of the drive rod. By this design, the bridge between the two shots can be made particularly wide and thus stable. This contributes to further increase the burglar resistance of the window according to the invention.

To further increase the comfort in the operation of the window according to the invention, it is beneficial if the wing is biased by a spring element in the gap ventilation position.

The bias of the wing in the night ventilation position requires according to another advantageous embodiment of the invention, a low structural complexity when provided for biasing the wing in the gap ventilation position pretensioner has a biased by the spring element bolt and if the bolt at least one the distance of the two recesses from each other has corresponding range of motion. The pretensioner is simply attached to the wing or the frame, so that the bolt can be supported on the respectively opposite component.

FIG. 1 shows a window with a wing 2 mounted on a frame 1 and with an espagnolette fitting 3. The wing 2 is shown tilted about a horizontal tilting axis 4 in a tilted position and is held by an opening shears 5. The wing 2 can be moved against the frame 1 and bring in a closed position in which it is locked in the frame 1. Furthermore, the wing 2 can be rotated about a vertical axis of rotation 6. At the intersection of the axes 4, 6, the window has a corner bearing 7. The Ausstellschere 5 is held on a pivot bearing 8, while on the tilting axis 4 away from the corner bearing 7, a tilting bearing 9 is arranged. In the area of the tilting bearing 9, of course, an unillustrated wing lifter can be arranged, which compensates settlements of the wing 2.

The espagnolette fitting 3 has a longitudinally displaceable drive rod arranged in a groove of the wing 2. On the drive rod a plurality of locking pins 10, 10 'are arranged. The locking pins 10, 10 'are frame-fixed striking plates 11, 11' opposite. One of the Striker plates 11 'is arranged on a scissor arm 12 of the Ausstellschere 5.

The drive rod of the drive rod fitting 3 can be driven by a handle 13 and the locking pins 10, 10 'move. In the illustrated position, the handle 13 is in the tilted position marked K. If you move the handle 13 in the position marked D, the espagnolette fitting 3 is in a rotational position in which the wing 2 can rotate about the axis of rotation 6. In the position indicated by Z, L, the handle 2 is optionally in the closed position Z, in which it is locked to the frame 1 or in a night ventilation position L, in which it is a gap far away from the frame 1. A pretensioner 22 pushes the wing 2 resting loosely against the frame 1 far away from the frame 1. Furthermore, the espagnolette fitting 3 has a striking plate 14 arranged on the tilting bearing 9 and a striking plate 41 arranged close to the corner bearing 7.

Figure 2 shows the arranged on the tilting bearing 9 strike plate 14 of the espagnolette fitting 3 of Figure 1. Dash-dotted in the drawing are several positions of a drivable by the drive rod lock pin 15 in the closed position Z, the gap ventilation position L, the rotational position D and the tilt position K shown. It can be seen that the closed position and the tilted position form the end positions in the range of movement of the locking pin 15, while the rotational position D occupies a middle position. The direction of movement of the locking pin 15 holding drive rod is marked in Figure 2 with a double arrow. The strike plate 14 has a central opening 16, through which the locking pin 15 located in the rotational position D from the strike plate 14 can be brought out. In one of the end positions of the range of movement of the locking pin 15, the striking plate 14 has two transversely to the direction of movement of the drive rod by the dimension a spaced receptacles 17 for the locking pin 14. The dimension a, for example, be 6.5 to 7 mm and limits the gap, in the wing 2 in the night ventilation position L is removed from the frame 2. In the one receptacle 17, the locking pin 14 is in the closed position Z, while the locking pin 14 is in the other recording 17 in the night ventilation position L. Both in the night ventilation position L and in the closed position Z, the locking pin 14 is located within an edge 18 of the striking plate 14. If an attempt is made to pry open the wing 2 located in the night ventilation position L, the strike plate 14 sets the same resistance to this escape attempt as it does in the closed position Z befindlicher wing 2. In the central region of the strike plate 14 also has a guide 19, which ensures that the located in the rotational position D locking pin 15 is moved transversely to the direction of movement of the drive rod by the amount a.

In an alternative, not shown embodiment of the striking plate, the two transversely to the direction of movement of the drive rod spaced receptacles 17 may be separated from each other by a web 21 for the locking pin 15. As a result, the wing 2 shown in Figure 1 is held particularly reliable in the gap ventilation position L and the closed position Z.

FIG. 3 shows one of the striking plates 11 of the espagnolette fitting 3 from FIG. 1. It can be seen here that the striking plate 11 has two elongate receptacles 20 for the locking pins 10, which are also elongated.

The receptacles 20 are separated by a web 21. Also by this strike plate 11, the wing 2 is reliably held both in the gap ventilation position L and in the closed position Z at a break-open attempt of the window shown in Figure 1.

FIG. 4 shows the pretensioner 22 provided for biasing the wing 2 in the gap ventilation position L in a sectional view. The pretensioner 22 has a housing 23 to be fastened to the wing 2 or the frame 1 from FIG. 1 and a bolt 25 prestressed out of the housing 23 by a spring element 24. The bolt 25 is supported on the frame 1 or the wing 2 opposite component and is guided by the dimension a axially displaceable. If you want to move the window in the closed position Z, the wing 2 can be pressed against the force of the spring element 24 against the frame 1. Subsequently, by actuating the handle 13 of the drive rod fitting 3 can be moved to the closed position Z.

Figure 5 shows in perspective the Ausstellschere 5 of the espagnolette fitting 3 of Figure 1. The arranged on the scissor arm 12 lock plate 11 'has a recess 26 in which the mounted on the drive rod, located in the tilt position locking pin 10' can move. A cover plate 27 covering the drive rod and connected to the wing 2 has a slot 28 in the movement range of the lock pin 10 '.

FIG. 6 shows the striking plate 11 'of FIG. 5 arranged on the scissor arm 12 with a plurality of positions of the locking pin 10'. The striking plate 11 'has two spaced apart by the amount a receptacles 29 for in the closed position Z and in night ventilation position L. located locking pin 10 'on. In the region of the rotational position D, a rocker 31 mounted pivotably about a rotation axis 30 is arranged. The rocker 31 has to the end positions of the locking pin 10 'sloping substantially mutually symmetrical ramps 32. This ensures that the locking pin 10 'can pass from an end position only on the intended side of the rocker 31 over in the other end position. As a result, the switching sequence of the various positions of the locking pin 10 'is set. If one moves the locking pin 10 ', for example, from the tilted position K in the direction of the closed position Z, the locking pin 10' can only reach the closed position Z. The gap ventilation position L is blocked by the rocker 31 and a web 33 arranged between the receptacles 29. If one moves the locking pin 10 'from the closed position Z in the direction of the tilted position K, the locking pin 10' is first guided at the one ramp 32 into the rotational position D. In this movement, the wing 2 shown in Figure 1 is pulled away from the frame 1 by the dimension a. Subsequently, the gap ventilation position L can be approached by return movement of the locking pin 10 '. To illustrate the possible movements of the locking pin 10 'are marked with arrows in the drawing.

Figure 7 shows the corner bearing 7 of the espagnolette fitting 3 of Figure 1 in a sectional view. The corner bearing 7 has a perpendicular to the plane arranged bearing axis 34 to allow tilting and lying in the plane of the bearing axis 35 to enable the rotation of the wing 2. A frame-fixed bearing member 36 has a sleeve 37 for receiving a longitudinally displaceable bolt 38 of a wing-fixed bearing part 39th The bolt 38 can be by the amount a from the sleeve 37th pull out, which can be generated in the gap ventilation position L in the region of this corner bearing 7, a corresponding gap between the frame 1 and the wing 2. The bolt 38 is shown in the pulled out of the sleeve 37 position. An optionally between sleeve 37 and bolt 38 arranged spring element 40 biases the bolt 38 and thus the wing 2, for example, in the position in which the wing 2 is used on the frame 1.

Figure 8 shows the near the corner bearing 7 arranged strike plate 41 with a corner bearing control of the espagnolette fitting 3 of Figure 1 and dash-dotted in different positions arranged locking pin 42. The striking plate 41 has two rockers about pivot axes 43, 44 mounted rockers 45, 46. The rockers 45, 46 are biased in the position shown. Furthermore, the strike plate 41 has two spaced-apart receptacles 47 for the locking pin 42 located in the closed position Z and in the slot ventilation position L. The first rocker 45 has a ramp 48 which guides the locking pin 42 located in the closed position Z into the rotational position D. During this movement, the other rocker 46 is pivoted away and then snaps back into its drawn position. From the rotational position D, the locking pin 42 can be moved either in the gap ventilation position L or in the tilted position K. If the locking pin 42 is moved from the tilted position K into the closed position Z, the first rocker 45 is pushed away.

The corner bearing control controls via the switching sequence of the locking pin 42, the movement of the wing 2 relative to the frame 1. The ramp 48 of the first rocker 45 presses during the movement of the locking pin 42 from the closed position Z in the rotational position D, the wing 2 of the frame 1 way. Thus, the bolt 38 of the corner bearing 7 shown in Figure 7 is pulled out of the sleeve 37. The movement of the wing 2 against the frame 1 during the movement of the locking pin 42 from the rotational position D into the tilted position K can take place via the spring element 40 of the corner bearing 7.
