Description

The invention relates to a closure for an espagnolette fitting for locking a window, a French window or the like with a pivotable against a frame wings, comprising a closing element and a closing element arranged opposite the locking plate.

Closures for a drive rod fitting usually have an elongated receptacle in the strike plate for a bolt-shaped closure element and are known in practice. The elongate receptacle has a ramp, against which the closing element passes during the movement of the drive rod fitting in a locking position. The locking element rubs when locking the window along the ramp, pulling the wing against the frame. In this case, a resilient seal between the frame and the wing is compressed. Thereafter, the closure element rubs along the elongated receptacle until it is held in the elongated receptacle. Thus, the wing is locked in the frame.

A disadvantage of the known window is that the movement of the closing element along the ramp and in the elongated recording requires a very large amount of force. Therefore, the run-on slope can be arranged only very slightly inclined to the direction of movement of the closing element. However, this leads to a low suit of the wing against the frame and thus to a low tightness of the window.

The invention is based on the problem, a window, a French window or the like of the type mentioned in such a way that it can be closed with very little effort and ensures a particularly high density.

This problem is inventively solved in that the striking plate or the closing element is guided movably orthogonal to a frame plane and that a movement of the striking plate or the closing element in dependence on the position of the closing element in the strike plate is controllable.

By this design, the movement of the closing element is separated into the locking position in the recording of the striking plate of the suit of the wing against the frame. By controlling the movement of the striking plate in dependence on the position of the closing element can be achieved that a movement of the striking plate only takes place when the closing element has produced a positive connection with the striking plate. This makes it easy to avoid that the closing element generates high frictional forces in the locking position in the locking position in the movement. Thanks to the invention, the espagnolette fitting can be initially moved with little friction in the locked position. Only when the espagnolette fitting is in the locked position, the wing is pulled against the frame. Thus, the window according to the invention can be closed with particularly little effort and ensures a high degree of tightness. In addition, it is also conceivable to use the invention for parking the sash relative to the frame. Here, the striking plate or the closing element would move in the opposite direction as when tightening the wing. Depending on the number and Distribution of the closures on the window can also be turned off in parallel.

The striking plate could be driven by the movement of the closing element and vice versa. To further increase the comfort in the operation of the window according to the invention, however, it contributes, when the strike plate or the closing element connected to a controllable actuator and the actuator is designed for orthogonal movement of the striking plate or the closing element to the frame plane. Preferably, the actuator moves the strike plate or the closing element during the unlocking process of the espagnolette fitting back into a relaxed position of the wing relative to the frame.

A high force to suit the wing against the frame can be easily generated according to another advantageous embodiment of the invention, when the actuator z. B. is an electric motor, pneumatic or hydraulic drive.

Activation of the actuator is particularly simple, according to another advantageous development of the invention, if a sensor detecting the position of the closing element is provided for driving the actuator.

The sensor could, for example, directly detect the position of a drive rod of the drive rod fitting. However, since the drive rod is usually arranged on the wing and the strike plate with the electrically controllable actuator on the frame, this design leads to a separation of the sensor from the actuator. The cost of laying electrical lines for connecting the sensor and the actuator can be particularly low according to another advantageous embodiment of the invention hold when the sensor is arranged in the strike plate.

The sensor is particularly inexpensive according to another advantageous embodiment of the invention, when the sensor z. B. is a reed switch or a pressure contact.

The strike plate is held reliably according to another advantageous embodiment of the invention in the tightened position of the wing, when the strike plate is guided against a fixed base member in a guide groove or on an eccentric.

The structural complexity of the intended movement of the striking plate can be kept particularly low according to another advantageous embodiment of the invention, when the guide groove is inclined to the range of movement of the closing element.

A separation of the movement of the closing element in the locking position of the movement of the striking plate designed according to another advantageous embodiment of the invention structurally particularly simple when a recording in the strike plate for the closing element is shorter than the movement range of the closing element. With this design, the closing element for locking the espagnolette fitting can be inserted friction in the recording of the striking plate. Only when the closing element comes against the end of the recording, the striking plate is moved and the wing pulled against the frame. The movement of the strike plate into the position remote from the wing may be carried out by the actuator or alternatively by the force of movement of the closure element.

A drive of the striking plate by the movement of the closing element is particularly simple according to another advantageous embodiment of the invention, when the eccentric or a penetrating into the guide pin is rotatably mounted.

The structural effort to move the strike plate in the orthogonal from the frame plane position can be kept particularly low according to another advantageous embodiment of the invention, when the strike plate is biased in the orthogonal from the frame plane position. With the espagnolette lock unlocked, the striking plate thus reliably returns to the starting position in which the closing element can be easily inserted into the striking plate.

According to another advantageous embodiment of the invention, the closing element is guided in an orthogonal to the longitudinal extent of a drive rod extending slot in the drive rod and in a sliding groove in a face-plate. The gate groove extends along the longitudinal extent of the faceplate. By this arrangement, it comes when moving the espagnolette both to a movement of the closing element in the direction of displacement of the drive rod and orthogonal to the frame plane, including a displacement of the closing element transverse to the movement of the drive rod.

The invention is particularly simple when the closing element is formed by an eccentric pin. When the eccentric pin is rotated, a movement of the closing element also takes place orthogonally to the frame plane. Depending on the direction of rotation, the wing is tightened or loosened relative to the frame. Especially comfortable The eccentric bolt can be driven by means of the actuator.

In a further, low-cost embodiment of the invention, the closing element has a thread and along a threaded axis by the actuator, in particular a worm gear, rotatable. By turning the closing element this is moved orthogonal to the frame plane. Depending on the direction of rotation, a suit or a relaxation or a shutdown of the wing is achieved with respect to the frame.

It is further provided that the strike plate is driven by the drive rod. The striking plate is rotated 90 degrees compared to the usual way of installation, so that the side walls of the striking plate run along the face plate rail. An upper side of the striking plate has an opening which points in the direction of the closing element and cooperates therewith.

This embodiment proves to be particularly stable if the striking plate has a guide whose direction runs parallel to the direction of movement of the drive rod. The guide is formed for example by an anchored in the wing or wing profile guide element which engages behind the strike plate. The guide element could be designed as a mushroom pin and engage behind a slot located on an underside of the striker plate. The guide could also be formed by located on the strike plate guide parts, which engage behind a guide channel on the sash profile. By the leadership of the strike plate is prevented when force on the strike plate, z. As in a Aushebelversuch, the strike plate or the drive rod can not withstand the forces and bends.

The invention allows numerous embodiments.

For example, it would be conceivable to turn the striking plate along a vertical axis of the strike plate and thus, depending on the direction of rotation, to move a partial region of the strike plate orthogonally into the frame plane or out of the frame plane.

Further, a tilting of the striking plate along a horizontal axis of rotation would be possible to achieve depending on the tilting direction orthogonal movement of the striking plate to the frame plane.

Depending on the direction of rotation or tilting, the wing can be pulled into or removed from the frame.

FIG. 1 shows a window with a wing 2 mounted on a frame 1 and with an espagnolette fitting 3. The wing 2 is connected to the frame 1 via bearings 4 and has a handle 5 for driving the espagnolette fitting 3. The espagnolette fitting 3 has a plurality of closures 6 on, with which the wing 2 in the frame 1 can be locked. A drive rod 7 of the espagnolette fitting 3 is arranged in the wing 2.

FIG. 2a shows a sectional view through the window in the region of one of the closures 6 from FIG. 1 along the line II-II. The closure 6 has a bolt-shaped closing element 8 fastened on the drive rod 7 and a striking plate 9. The striking plate 9 is arranged in the frame 1. In the illustrated position, the espagnolette fitting 3 is in a locking position in which the wing 2 is locked in the frame 1. In this case, the closing element 8 is in a receptacle 10 of the striking plate 9. The striking plate 9 is movable in the frame 1 relative to a base member 11 In contrast, FIG. 2b shows the position of the striking plate 9 in a position close to the wing 2. It can be clearly seen that a seal 12 is pressed together between the wing 2 and the frame 1 in Figure 2a, while the seal 12 in the position shown in Figure 2b loosely applied to the frame 1.

Figure 3 shows the striking plate 9 with the base member 11 and a controllable actuator 13 in a perspective view. The actuator 13 is designed here as an electric motor drive and drives the strike plate 9 via a spindle 14. The striking plate 9 is guided in inclined to the direction of movement of the closing element 8 shown in Figures 2a and 2b arranged guide grooves 15. The base member 11 is fixedly disposed in the frame 1. Upon actuation of the actuator 13, the striking plate 9 is moved over the spindle 14 and displaced by the guide grooves 15 transversely to the direction of movement of the closing element 8. Thus, the positions shown in Figures 2a and 2b are approached and the wing 2 pulled against the frame 1. The striking plate 9 has a sensor 16 designed, for example, as a reed switch for detecting the position of the closing element 8 shown in FIGS. 2a and 2b. Only when the sensor 16 detects that the closing element 8 is in the elongated receptacle 10 of the striking plate 9 and thus in the locking position of the closure 6, the actuator 13 is driven and the strike plate 9 is tightened, so that the wing 2 in the frame. 1 , So is drawn into the position shown in Figure 2a.

FIG. 4 shows a perspective view of a further embodiment of the striker plate 9 displaceably guided in a guide groove 20 with a fixed base element 17.

In the guide groove 20, the outer boundaries of the strike plate 9 are guided. The striking plate 9 is connected via an eccentric 18 with the base member 17. The eccentric 18 can be driven by an actuator 19. By driving the eccentric 18, the striking plate is also displaced, as described for Figures 2 and 3.

FIG. 5 shows a further embodiment of the striking plate 9 guided on a base element 21 with the closure element 8. The base element 21 has guide grooves 22 arranged inclined to the movement direction of the closure element 8. In the guide grooves 22 are rotatably mounted pin 23 of the striking plate 9 a. Furthermore, the receptacle 10 in the strike plate 9 for the closing element 8 is shorter than the movement range of the closing element 8. The strike plate 9 is biased by a spring element 24 in a position which corresponds to the position shown in Figure 2b, the wing 2 near position. When the closing element 8 passes when driving the drive rod fitting 3 against the end of the receptacle 10 of the striking plate 9, the strike plate 9 is moved. The displacement of the striking plate 9 is guided by the guide grooves 22. In this case, the striking plate 9 enters a position which corresponds to the position shown in Figure 2a, the wing distant position.

FIG. 6a shows a further embodiment of the invention. Here, the closing element 8 has a thread 29 and is guided along a threaded axis, orthogonal to the frame plane movable on the frame 1. The closing element 8 engages in a locked position driven by the drive rod 7 and connected thereto, wing-side strike plate 9. The drive rod 7 and the overlying cuff rail are arranged as usual in a groove of the wing 2. The strike plate 9 against it is arranged so that an opening 27 in the striking plate 9 in the direction of the closing element 8 and the side walls of the striking plate 9 extend along the face plate - the striking plate 9 is thus rotated relative to the usual arrangement by 90 degrees. In order to avoid deformation of the striking plate 9 or the drive rod 7 when the force is applied to the strike plate 9, the strike plate 9 additionally has a guide 25. The guide 25 is in Figure 6a, a guide member 26 which is formed as a fixed in the sash profile mushroom pin and engages behind a located on an underside of the striker plate 9 slot. Forced forces can thus be dissipated in the sash profile. When the wing 2 is closed, the striking plate 9 is moved by the drive rod 7 in the locked position, so that the strike plate 9 is engaged behind by the closing element 8. If the striking plate 9 is in the locked position, this is detected by the sensor 16 and the actuator 13 is activated. In the embodiment shown in Figure 6a, the actuator 13 is an electric motor and drives a worm gear 28, consisting of a worm and a gear on. The worm gear 28 ensures the movement of the closing element 8 along the thread axis, orthogonal to the frame plane. Depending on the direction of rotation of the electric motor, the closing element 8 is moved into or out of the plane of the frame in the frame plane and thus ensures a tightening or parking the wing relative to the frame. FIG. 6a shows the wing 2 pulled into the frame 1, as can also be seen on the compressed seal 12.
In contrast, FIG. 6b shows the position of the closing element 8 in which the wing 2 is placed opposite the frame 1 or loosely in the frame 1. It can be clearly seen that the seal 12 is located loosely between the wing 2 and the frame 1.

Striker plate 9 and closing element 8 could also be placed elsewhere on the frame or sash profile, z. B. in the wing flap.
