Description

Motorized drive

The invention relates to a motor drive for at least one axis of a closed position in an open position pivotable wing of a window or a door according to the preamble of claim 1.

Drives of this type are described for example by DE 295 14 179 LJ 1 and the

US 4014136 already known. Here, the motor drives are mounted on the frame or wing of a window or a door and have a transmission member which engages the wing or frame by means of a bearing block or a console. If the motor drive attached to the frame, the console is assigned to the wing. In an arrangement of the motor drive on the wing, the console is attached to the frame. In the cited documents, the transmission member is a chain which is wound up in a housing of the motor drive.

Other versions provide instead of the chain Ausstellarme or the like, which are pivoted indirectly via auxiliary arms or directly via motors. Again, the effective as a transfer members Ausstellarme attack on consoles.

A disadvantage of the aforementioned embodiments is that the drive and / or the transmission member can be damaged by the user, if this manually depressed the open via the drive wings. Depending on the arrangement of the drive on the wing and the size of the wing there is a lever arm, which causes a large force on the drive and / or the transmission member.

Accordingly, the transmission elements are to be dimensioned correspondingly large and to secure the drives against a manual push back. Both increase the production costs and thus the costs.

Therefore, the object is to provide a motor drive, the one

Damage to the transmission element and / or the drive avoids, while allowing a simple and cost-effective production.

To solve this problem, the invention provides that the connection of the transfer member and the wing or frame by means of a frictional Connection is made, which is solvable by exceeding a reference force. By means of the solution of the connection of the transmission member and the wing when exceeding the reference force is ensured no damage to the transmission member or the motor drive arise when the wing is blocked and the drive tries to bring this in an open position. In this case, the motor drive can be constructed comparatively simple, so the complex mechanical electronic solutions are avoided in the drive. The separation of the transmission member of the wing or the frame also allows a manual decoupling, for example in the event of a power failure, engine failure or for cleaning purposes, when the wing is tilted exclusively via the drive.

A particularly expedient embodiment provides that the connection of the transmission member and the wing or the frame via the motor drive in the closed position of the wing. As a result, the intended use of the drive can be ensured if after a decoupling of the non-positive connection of the motor drive back into the

Position is brought, which corresponds to the closed position, so that the non-positive connection is preferably restored automatically via the drive when taking the end position. Closed position means that the wing rests against the frame. A locking of the wing to the frame is not necessary here.

A particularly simple embodiment provides that the non-positive connection via a catch. The catch can be used as a known mechanical catch a to be overcome when snapping or snapping force z. B. by springs o.a. cause.

It is particularly advantageous if the catch consists of a base profile and a flange covering the base profile, wherein the flange is attached to the transmission member and the frictional connection between the base profile and the flange acts. The catch is thereby covered and protected against the ingress of dirt or the like. Here, the console consisting of the base profile and the flange by separation of these components is practically dissolved. The flange is fixedly assigned to the transmission element and the base profile to the wing or frame. To avoid mechanical components can be provided that the non-positive connection via a magnetic catch. Magnets are simple and inexpensive to get as a standard components with a desired holding force, so that an adaptation to wing sizes and weights can be achieved. In addition, precise alignments of the items are dispensable in a magnetic catch.

Therefore, it can also be provided for this purpose that the base profile consists of a ferromagnetic plate. This allows a very simple and inexpensive design. The magnet is mounted between the plate and the flange and fastened, for example, to the flange.

It is also advantageous if the motor drive is mounted on the frame and the flange protrudes over a wing edge on a space inside wing siding. As a result, when the reference force is exceeded, the flange can be released from the interior side wing sight surface and the wing can be closed without hindrance.

A particularly simple embodiment still provides that the transmission member is a back-rigid chain.

In the drawings, further advantageous embodiments can be seen. It shows:

1 a tilt and turn window with a turn-tilt fitting and a motor drive,

Fig. 2 shows a wing, a frame and individual components of a motor

drive,

Fig. 3 is a window with console in a closed position and Fig. 4 is a window in section along the line IV-IV in Fig. 3rd

In Fig. 1, a frame is generally indicated at 10 and a wing generally at 12. The wing 12 is tiltable with respect to the frame 10 via a tilting axis 14 or rotatably mounted about an axis of rotation 16 parallel to the frame member 17. For this purpose, a non-illustrated corner bearing is provided at 18, which allows both the tilting movement about the tilting axis 14 and the rotational movement about the rotation axis 16. -A-

Further, a tilt lock is provided at 20, which allows the tilting movement about the tilting axis 14 and can be opened for the rotational movement about the rotation axis 16. Between the upper frame leg 22 of the frame 10 and the upper wing leg 24 of the wing 12, a display device 26 is provided which limits the Kippöffnungsweite of the wing 12 relative to the frame 10 to the position shown in FIG. 1 and which in the rotational movement of the wing 12 to the pivot axis 16 at the upper wing leg 24 of the sash frame 12 is set in parallel position to this, by cooperating bars 28, 30. The bolt 30, the tilting bearing 20 and possibly not further drawn here locking element pairings for locking the locking of the wing 12 to the frame 10 by Driving rod means 32 controlled in a known manner.

In Fig. 1, the handle 38 is switched to the switching position tilting and the wing 12 is in tilted position.

On the upper frame leg 22, a motor drive 40 is provided, which can be used as an alternative to manual over the handle 38. The motor drive 40 has a housing 41 fixed in the exemplary embodiment on the frame 10, in which a chain 42 as a transfer member and one on the chain

42 acting - not visible here - drive member and this driving motor are included. The chain 42 engages on the side facing away from the housing 41 on a bracket 43 on the wing 12 at. Usually, the chain 42 is on the console

43 pivotally hinged. When mounting the drive 40 on the wing 12, the bracket 43 is attached to the upper frame leg 22.

Deviating from this, alternative drives are shown in FIG. 2 on the wing 12 and the frame 10. At the wing end surface 44, a motor drive 45 is mounted, which can be coupled directly to a drive rod gear. Alternatively, in a Falzausnehmung 47, a motor drive 46 may be provided which couples indirectly via a driver on the wing-side drive rod gear. The motor drives 45, 46 serve to drive the drive rod means 32. In order to accomplish the opening movement of the wing 12, the motor drive 40 is provided, which is also mounted in the embodiment of FIG. 2 in a not visible here Falzausnehmung. At the wing sight surface 44, the console 43 is fixed, which is shown in FIG. 2 of a base profile 50 and a cross-flange 51 this consists. On the flange 51, a permanent magnet 52 is attached, for example by gluing. The magnet 52 and consisting of a ferromagnetic plate base profile 50 form a frictional catch 53, via which the transmission member shown in FIG. 1, designed as a chain 42 is attached to the wing 12. The transmission member may preferably be a back-stiff chain 42 which engages the flange 51 by means of an axle 54. Thus, the connection of the transmission member (chain 42) and the wing 12 is given by a non-positive connection. If a reference force is exceeded, the frictional connection is without

Damage to the connection partners can be solved. By means of the solution of the connection of the flange 51 of the base profile 50 when exceeding the reference force is ensured that no damage to the transmission member, the motor drive 40 or the console 43 arise when the wing 12 is blocked and the drive 40 this in an open position tried to bring or the wing 12 is open (for example, according to FIG. 1) and an operator tries to close the wing 12.

In addition to the design of the latch as a magnetic catch 53, the connection can of course also be done by a known mechanical catch. The catch 53 can be a force to be overcome when snapping or snapping z. B. by springs o.a. cause. However, the configuration as a magnetic catch 53 has the advantage that magnets 52 are to be obtained as standard components easily and inexpensively with a desired holding force, so that an adaptation to wing sizes and weights can be achieved. In addition, precise alignments of the items are dispensable in a magnetic catch.

It is particularly useful if the connection of the chain 42 and the bracket 43 can be done via the motor drive in the closed position of the wing 12. If, after a decoupling of the non-positive connection via the catch 53, the motor drive 40 is returned to the position which corresponds to the closed position according to FIG. 3, the non-positive connection automatically closes via the drive 40 when the end position of the motor drive 40 is taken again. The chain 42 used in the embodiment moves at a closing movement of the motor drive 40 attached to the transfer member flange 51 zoom back to the frame 10 zoom. Is the wing 12 already ajar manually and with decoupling of the latch 53 on the frame 10, the catch 53 finally couples automatically near the end position of the transmission element again. This also takes place in a preferably used chain 42, which has a further degree of freedom relative to a stay arm, since the chain 42 can have no or only a very small lateral deviation of the flange 51 shortly before the final reception in the housing 41.

Although it may be provided that the bracket 43 is attached to the striking on the frame 10 rollover surface 55, it is more advantageous, however, when the motor drive 40 is mounted on the frame 10 and the flange 51 via a wing edge 56 away on the space inside vane face 44 sticks out. As a result, when the reference force is exceeded, the flange 51 can be released from the room inside wing sight surface and the wing 12 can be closed without hindrance.

However, if the flange 51 is arranged so that it lies between the rollover surface and the frame 10, special measures must be taken to prevent abutment of the wing 12 to the bracket 43 and the flange 51.

That the catch 53 from the base profile 50 and the base profile 50 overlapping flange 51 is, has the advantage that the catch 53 thereby covered and against the ingress of dirt o.a. is protected. This is particularly advantageous for mechanical Schnäppern.

In the closed position of the wing 12 according to FIGS. 3 and 4, it can be seen that this rests with the striking on the frame 10 rollover surface 55 at this. The chain 42 passes through an opening 58 (FIG. 2) in a frame end face 57. The opening 58 and the chain 42 are covered by the flange 51.

Now, if the motor drive 40 is set in motion and the wing 12 is blocked, then the magnet 52 releases from the base profile 50 and the drive 40 and the transmission member is brought without the wing 12 in its end position. If the drive 40 is closed again from this actual open position when the magnet 52 is uncoupled, the chain 42 assumes its position again at least shortly before the complete retraction into the housing 41, and the magnet returns to the contact with the base part 50.
