EP1837470B1 - Automatically powered window or door element - Google Patents

Description

The invention relates to a window or door element according to the preamble of claim 1.

Windows and doors with an automatic drive are known in the art, so from the DE 10 2004 031 212 B3 which discloses the features a) to d) of claim 1.

The automatic drives are designed and arranged such that the frame and the sash are automatically pivotable about an axis of rotation relative to each other by the drive or by components of the drive.

In the problem case, if with closed elements e.g. the power supply is interrupted or a defect of the drive has occurred, the element should still be able to be opened manually.

Usually, automatic drives are mounted visibly resting on the frame or sash of the elements. If it comes to the problem mentioned, the drive is easily accessible and can be decoupled between glare and casement to open the movable wing can. The disadvantage here is the visible arrangement, which is often undesirable for optical reasons.

From the DE 101 22 261 an electric motor drive for a Parallelausstellfenster is known, which is partially arranged in the profile frame. The drive is coupled with a hardware system. In the case of a problem, with an interruption of the power supply (power failure) or a defect of the drive, it is possible to decouple the automatic drive via a so-called coupling pin, which is accessible from the outside. This offers a possibility for emergency release, in which the window or door element can be opened manually. The disadvantage is the massive Coupling pin, which is visible on the outside of the wing and affects the visual appearance.

In the unpublished DE 10 2005 006 313 Furthermore, an automatic drive for the tilting operation of a turn-tilt window or a tilt-turn window is described. This drive is arranged between the blind and the wing frame, wherein the actual drive device is arranged with the drive housing in an advantageous manner on the casement on the axis of rotation in the corner region of the wing. The drive device is coupled via a shear-resistant drive chain with the frame, which makes it possible to move the sash at the side facing away from the pivot bearing - usually upper - side relative to the frame, whereby the sash pivots about its horizontal - usually lower - tilt axis becomes.

If there is a problem, it is possible to manually open the wing of the element by untwisting - that is, swiveling about the further axis of rotation oriented perpendicular to the tilting axis. As a result, access to the automatic drive is guaranteed, for example, to repair or replace.

The construction has proven itself in that respect. The problem is that when using the drive on a window or door element having only a single axis of rotation, no manual emergency opening of the wing is possible in case of failure of the automatic drive when the wing is in its closed position.

The invention first has the object to solve the problems described above in a simple manner.

Thus, first of all, the generic window or door element is to be further developed in such a way that a mechanical unlocking of a drive, which in the closed state is completely concealed from the outside, can be realized in a particularly simple manner.

The invention solves this problem by the subject matter of claim 1.

Thereafter, the coupling device is completely concealed lying in the movable sash, in the fixed frame or between these elements and it is designed so that it can be decoupled from a place outside the glare or sash without damaging the frame or sash. In this way, the coupling device does not appear optically in the closed state of the window and yet it can be decoupled in a simple manner.

The coupling device is designed such that it can be decoupled in the closed state through a gap between the blend and the wing frame. Also, the coupling device optical does not appear in the closed state of the window or at least to a non-relevant extent in appearance and it is additionally implemented a particularly simple way of decoupling without having to damage a frame part of the window for emergency opening.

Alternatively, the coupling device to an actuator, which is preferably preferably via a remote control device, wirelessly operable and which is adapted to decouple the coupling device.

It is expedient if the actuator is designed as an electromotive or electromagnetic actuator.

Alternatively, the actuator may be designed as a fluid-operated, in particular pneumatic or hydraulic, actuator.

It is also conceivable that the actuator of the coupling device is designed cost-effective and easy to handle as an electric or a permanent magnet.

Advantageous embodiments can be found in the dependent claims.

According to an advantageous feature that ensures a particularly safe emergency opening, the coupling device is designed such that it can be manually decoupled by means of a mechanical device which is insertable in the closed state of the wing in the gap between the frame and sash.

According to a particularly preferred, functionally reliable variant, the coupling device is designed such that the connection of the drive between the glare and sash frame in the opening direction (x) of the wing is decoupled.

According to a further advantageous feature, the coupling device has a movable component, which in each case can be released manually - possibly with the aid of the tool - from a coupling position. It is advantageous if the movable component of the coupling device is movable transversely to the opening direction (x).

Particularly preferably, the movable component of the coupling device is a pin or bolt. A bolt is a low-cost, easy-to-integrate into the construction and handling component.

It is useful if the bolt has securing means which prevent accidental opening. So offers itself as a securing means a clip on the bolt. The preferably used locking pin or pin is designed so that it is accessible from the outside; preferably with the aid of a tool.

The coupling device is based on a slide principle so that the coupling device in the decoupled state in the opening direction of the wing can slide out of a sliding block. These variants are also easy to build and functionally reliable.

The emergency release according to the invention can be realized in a structurally particularly simple and cost-effective manner, as will be apparent in particular from the description of the preferred exemplary embodiments.

Alternatively, according to a less preferred embodiment, it is also conceivable for the pin to be separated by a gap between the blind and the sash frame by a short distance, e.g. protrudes by a few mm, so that it is easy to find and accessible.

The invention allows summarized in a simple manner a nondestructive opening of the wing in case of failure of the electric motor drive even in the closed state.

further embodiments of the invention.

FIG. 1 shows a section (top horizontally) through a window element, which is designed as a tilting window, which has a sash 2, which is pivotally mounted on a frame 1 to a generally horizontal axis of rotation (at the bottom of the window).

The frame 1 of the tilting window is rigidly or immovably connected to surrounding masonry or other elements. The pivotable sash 2 usually takes surface elements (not shown here), such. As glass, on.

Between the frame 1 and the casement 2 is concealed (i.e., not visible from the outside in the closed state) an automatic drive 3, usually provided with an electric motor.

The drive 3 here has a drive housing 25, which receives the electric motor in a preferred embodiment, and a sliding block 5, wherein the sliding block 5 and the drive housing 25 via a drive means, in particular a chain 8, are interconnected.

The drive housing 25 is disposed in a groove 4 of the movable sash and moves in such a manner when opening and closing the sash with the sash 2 (see Fig. 2 ).

The sliding block 5 of the drive 3 engages positively in a groove 26 of the frame 2 a. It is connected to the drive housing via the chain 8, which is designed here as a push chain, such that with the chain 8, the distance between the drive housing 25 and the sliding block 5 can be changed to open the window or close ( Fig.1 . Fig. 2 ).

The automatic drive 3 is designed for opening and closing about a horizontal axis of rotation of the wing. An insert of the drive to unscrew and close a wing about a vertical axis of rotation is also conceivable and readily feasible.

Between the frame 1 and the sash 2, a gap 6 is formed, which is sealed in the closed state by a seal 7, which may also be designed as a switching strip.

The gap 6 offers a possibility to realize a manual access to the drive, without having to be manipulated on the frame 1 or sash 2. A manual nondestructive access in the closed state is therefore according to the invention via the gap. 6

FIG. 2 shows how FIG. 1 a section through a tilting window (especially skylight window), but this time in an open, tilted state. The stationary frame 1 is preferably fixedly connected via a shear-resistant chain 8 of the drive 3 with the sash 2, which makes it possible to move the wing about its axis of rotation.

In Fig.2 the gap 6 has increased by a multiple and is used for example for ventilation.

The chain 8 as a link is anchored on the one hand in the wing frame side arranged drive 3 and can here, for example. be wound up or unwound over a pinion. On the other hand, the chain 8 is connected via the sliding block 5 with the frame.

Due to the design, due to the small size, is a connection element 9 of the coupling member 14 with the chain 8 on the frame side relatively far towards the center of the frame, ie, it is relatively far away from the gap 6.

The detachable coupling device according to the invention is arranged according to this specific embodiment on the side of the sliding block 5 on the frame 1.

Here, the coupling member 14 is formed like a slide, so that the coupling member 14 can slide out of the sliding block 5 with the connecting element 9 in the opening direction X of the wing.

FIG. 3 shows a part of the frame 1, in which the sliding block 5 is arranged or attached as a connection part for the drive. The sliding block 5 is designed in such a way that it has a groove channel 10 in the opening direction. Transverse thereto is a further recess 12, which - as described below - is designed for a safety pin.

In FIG. 4 the coupling part 14 corresponding to the sliding block 5 is shown.

The coupling part 14 has a connection element 9, which is to be regarded as a quasi last chain link of the chain 8. The chain 8 is therefore permanently connected to the coupling part 14 via the connecting element 9.

Corresponding to the groove 10 of the sliding block 5, the coupling part 14 is provided with a slide-like web shape 11 so that the coupling part 14 can be inserted into (or against) the opening direction in the groove 10 of the sliding block 5. Here, the entire wing is connected to the frame or decoupled.

The coupling member 14 is positively in the sliding block 5 in desired position, so both parts with a (not shown here) component (locking pin or locking mechanism) are coupled together. In the preferred embodiment, a bolt is inserted into the transverse grooves 12 and 13, so that the coupling part 14 is positively connected to the sliding block or to the entire frame.

FIG. 5 shows detached in a side view of the sliding block 5, in which the coupling part 14 is inserted. Good to see is the T-slot-shaped configuration of the groove 10 of the Nutenstein 5, in the opening direction in the slide-like manner, the coupling member 14 is inserted with its carriage (webs) 11.

Upon reaching the desired position of the two components to each other, the grooves 12 and 13 are located on an axis 15th

FIG. 6 shows again the FIG. 5 , the sliding block 5 with the inserted coupling part 14, wherein in this plan view this time in the grooves 12 and 13 a locking pin 16 is inserted on the axis 15.

The securing bolt 16 realizes a positive connection of sliding block 5 to the coupling part 14, so that in a simple manner a securely acting coupling device for driving the window is realized. To release this connection, the securing bolt 16 can be bent transversely to the opening direction of the wing.

Preferably, the securing bolt 16 is arranged in such a gap near the gap 6 that it can be easily moved out of the grooves 12 and 13 even with the wing closed. This ensures a non-destructive emergency release.

The FIGS. 7 and 8 show once again the safety pin 16 in a plan view, it being well seen that the safety pin 16 additionally has a clip 17 which has a crank 18 at the end. As a result, an unintentional slipping out of the securing bolt from the grooves 12 and 13 is prevented.

In a variant of the securing bolt, which is not shown here, it can be designed in such a way that the bolt itself emerges through the gap 6 or the clasp 17 is designed in such a way that it emerges from the gap 6.

This makes the emergency release even easier to access. Other variants of a transverse safety device are also possible (safety bolts).

The FIGS. 9 and 10 show completely different solutions of a transverse fuse of the coupling device according to the invention between glare and sash.

In FIG. 9 is the sliding block 5 described with its groove 10 in the opening direction in the manner of FIG. 3 shown. As in Figure 3 Here too, the coupling part 14 is introduced. However, the fuse is not a safety pin, which can be removed manually (as described), but via an electromotive or electromagnetic unit, via which a pin 19 can be extended and retracted.

The releasable coupling device thus consists of the elements sliding block 5 with the not shown here, the corresponding coupling part 14, the bolt 19 and the electromotive or electromagnetic actuator, which is adapted to the bolt 19 and extend.

For this, e.g. a wiring through the gap 6 are arranged on the surface of the window frame. In the problem case, the bolt 19 can then be easily withdrawn by means of a battery from the outside.

Variants of the power supply, the bolt assembly or the mechanism (electromagnetic, motor) are also feasible.

FIG. 10 shows a coupling device which is operable without power. In this case, a rocker 21 is actuated via a permanent magnet 20 from a position outside of the window or door elements. The rocker 21 is designed such that on the one hand has a safety lever 22 and on the other hand, an actuating lever 23rd

The rocker 21 is movably mounted at a pivot point in the sliding block 5 and is held by a spring element 24 in a starting position.

The coupling member 14 (not shown here) can be pushed from the front simply on the sliding block 5 in the groove 10 and locks independently in desired position. This allows the spring-loaded movable rocker. A release is possible only with the permanent magnet 20.

The rocker 21 is responsive to a magnetic member 25 disposed on the operating lever 23, so that the securing lever releases the coupling member 14 again. This embodiment allows in a simple manner without complex mounting means an emergency release of the drive, or the window.

The FIGS. 9 and 10 are to be understood as a schematic representation of the individual variants symbolize. Of course, the emergency releases can also be done differently in detail. In particular, the arrangement of bolts and lever in the profile direction is addressed here, which makes machining of the profiles (eg drilling) superfluous.
