The housing and the output element each have an elongated shape. The elongated output element extends parallel to the longitudinal axis of the housing over its entire length through the latter. The output element can be driven in both longitudinal directions via the motorized drive unit with an associated gear, with the two ends of the output element each being able to be coupled to a push rod or a push rod element.

Description

The invention relates to a locking and / or positioning drive for a window, a door or the like, with a housing, a motorized drive unit arranged in the housing with an associated gear and an output element that can be acted upon by the motorized drive unit with an associated gear. It also relates to a window, a door or the like with such a drive.

Window profiles offer little space for integrated drives. This is particularly the case when a wing drive is to sit directly on a push rod through which certain locking points are to be actuated. If the drive is located in the wing chamber of the wing profile, the installation options are limited. In addition, the current locking drives are relatively slow. Some conventional integrated drives also impair the thermal insulation of the window profile. Another disadvantage is that the previously known locking drives can only assume the "locked" and "unlocked" states.

The invention is based on the object of specifying a locking and / or positioning drive as well as a window, door or the like of the type mentioned at the beginning, in which the problems mentioned above are eliminated. The drive should be able to be installed in the window or door in a simpler and more space-saving manner, while the window or door should be able to be locked and unlocked faster or faster while maintaining the thermal insulation of the window or door, with the most compact structure possible and the greatest possible stroke can be positioned and, in particular, several locking points of the window or door can also be actuated simultaneously via the drive.

According to the invention, this object is achieved by a locking and / or positioning drive with the features of claim 1 or a window, a door or the like with the features of claim 13. Preferred embodiments of the drive according to the invention and of the window, door or the like according to the invention emerge from the subclaims.

The locking and / or positioning drive according to the invention for a window, a door or the like comprises a housing, a motorized drive unit arranged in the housing with an assigned gear and an output element that can be acted upon by the motorized drive unit with an assigned gear. It is characterized in that the housing and the output element each have an elongated shape and the elongated output element extends parallel to the longitudinal axis of the housing over its entire length through the latter and can be driven in both longitudinal directions via the motor drive unit with the associated gear, whereby the two ends of the output element can each be coupled to a push rod or a push rod element.

Due to this design of the drive, push rods located on both sides of the drive can be operated synchronously in the same direction. This means that only one motor is required for several locking points. In addition, the space otherwise occupied by the push rod (s) can be used for the drive because the output element forms, as it were, an intermediate element between the push rods arranged on both sides of the drive, which connects them. In addition, the drive according to the invention is very fast, and in practice it enables position adjustment in real time and real time locking.

The output element preferably extends with its two ends at least so far out of the housing that these ends even at a maximum Travel path of the output element still remain outside the housing. The coupling points of the output element with the push rods therefore always remain accessible.

The gear unit assigned to the motor drive unit expediently comprises a worm gear stage.

In certain cases it is also advantageous if the gear unit assigned to the motor drive unit comprises at least one spur gear stage.

The elongate output element is advantageously provided at least in sections in the manner of a toothed rack with a toothing with which an element of the transmission provided with a counter-toothing meshes.

According to a preferred practical embodiment of the drive according to the invention, the two ends of the elongated output element are each provided with a removable, exchangeable end piece for connecting a respective push rod or push rod element. In this way, depending on the sash or frame profile used, different end pieces can be used, which enables an optimal adaptation of a respective push rod or a respective push rod element to a respective end of the output element.

In this case, it is particularly advantageous if a respective end piece can be adjusted relative to the respective end of the elongate output element and can be attached in different positions so that it can be fixed.

A respective end piece preferably has an elongated shape, with a pivot pin which can be inserted into a corresponding opening of the relevant end of the elongated output element and at the opposite end The end is provided with a threaded opening, into which a head screw extending through an elongated hole provided in the relevant end of the output element can be screwed to fix the end piece rotatable about an axis of rotation defined by the pivot pin about an axis of rotation defined by the pivot pin.

It is also advantageous if a respective end piece has, on its side opposite the pivot pin, a connection pin, preferably aligned with the threaded opening, for connecting a push rod or push rod element. This connecting pin can in particular have a different length in the various exchangeable end pieces.

The housing of the drive preferably has the shape of an elongated cuboid. The drive can thus be integrated much more easily in the door or window profile.

It is also particularly advantageous if the housing, which has the shape of an elongated cuboid, is designed in steps, in particular in two steps. Via a corresponding housing step, the drive can in particular be placed on the sash or frame profile and fastened to it.

The motorized drive unit is preferably designed to generate a linear force of at least 600 N which acts on the elongated output element. This achieves a relatively high locking or positioning speed.

The maximum travel of the elongated output element is preferably at least 18 mm. This not only enables locking and unlocking of the window or the door. With the correspondingly large stroke, the window or door sash can also be brought into different positions such as, in particular, a tilted, closed and rotated position.

The window, door or the like according to the invention is characterized in that it comprises at least one drive according to the invention.

Their drive is preferably provided for locking at least one locking point and / or for tilting, rotating and / or moving the window or door leaf into its closed position.

The drive is advantageously at least partially integrated in the profile of the sash or the frame of the window or door.

For this purpose, the sash or frame profile can advantageously be provided with a recess, in the area of which or through which the drive extends at least partially into a chamber of the sash or frame profile. This means that the space under the push rod or the drive can also be used for the drive.

It is also advantageous if the drive with the steps provided on its housing is placed on the sash or window frame, and is preferably fixed thereon by screws or the like. The drive can be arranged partly in the chamber of the sash or frame profile and partly in the rebate clearance of the window or door.

The drive according to the invention can be kept relatively compact, in which case it can be mounted in the window or the door in a more simple and space-saving manner while maintaining the thermal insulation of the window or the door. The window or the door can be locked and unlocked or positioned more quickly than before. In addition, several locking points of the window or door can be operated simultaneously via the drive. As a result of the larger maximum stroke of the drive, the window or door not only locked and unlocked, but also adjusted to different positions such as a tilt, closed and rotating position in particular.

With the solution according to the invention, the space of a push rod and the space under such a push rod can be partially used for the drive by dividing a conventional push rod and reconnecting the push rod parts via the output element of the drive so that they are moved synchronously despite the division can. Due to the multi-step shape of the drive housing, it can be placed on the sash or frame profile with at least one step and connected to the profile, for example, by screws or the like. The drive according to the invention is very fast and practically enables real-time position adjustment and real-time locking. The drive can now be positioned and dimensioned in the sash or frame in such a way that the thermal insulation is not impaired.

the Figs. 1 and 2 show an embodiment of a locking and / or positioning drive 10 according to the invention for a window, a door or the like. The drive 10 is in the Fig. 1 shown with a complete housing consisting of two half-shells, while in the illustration according to Fig. 2 a half-shell of the drive housing is omitted.

The drive 10 comprises a housing 12, a motorized drive unit 14 arranged in the housing 12 with an associated gear 16, and an output element 18 which can be acted upon by the motorized drive unit 14 with an associated gear 16.

As from the Figs. 1 and 2 As can be seen, the housing 12 and the output element 18 each have an elongated shape. The elongated output element 18 extends parallel to the longitudinal axis of the housing 12 over its entire length through the latter and beyond it on its two end faces.

The elongated output element 18 can be driven in both longitudinal directions via the motorized drive unit 14 with the associated gear 16. The elongate output element 18 extends with its two ends 18 ′, which can be coupled in each case with a push rod or push rod element 20, at least so far out of the housing 12 that these ends at the maximum travel of the output element 18 in one direction or the other still remain outside of the housing 12. In order to ensure this with sufficient security, the total length of the output element 18 can be extended by a certain tolerance.

The gear 16 assigned to the motor drive unit 14 can in particular comprise a worm gear stage and / or at least one spur gear stage.

Like in particular from Fig. 2 As can be seen, the elongated output element 18 can be provided at least in sections in the manner of a toothed rack with a toothing 22 with which an element of the gear 16 provided with a counter-toothing meshes. Depending on the direction of rotation of the motorized drive unit 14, the output element 18 is thus moved linearly either in one direction or in the other. In the representations according to the Figs. 1 and 2 this elongated output element 18 is moved to the right with respect to the housing 12 with the maximum stroke.

The two ends 18 ′ of the elongated output element 18 are each provided with a removable, exchangeable end piece 28 for connecting a respective push rod or push rod element 20. In this way, depending on the sash or frame profile used, different end pieces can be used, which enables an optimal adaptation of a respective push rod or a respective push rod element 20 to a respective end 18 ′ of the output element 18. Exemplary embodiments of such an end piece 28 are described in more detail below.

Like that Figs. 1 and 2 In addition, it can be seen that the housing 12 has the shape of an elongated cuboid and is stepped, it being designed in two steps in the present case.

The motor drive unit 14 with associated gear 16 can be designed to generate a linear force of in particular at least 600 N acting on the elongated output element 18, which ensures a correspondingly fast, real-time locking and / or unlocking or positioning.

The maximum travel of the elongated output element 18 is in particular at least 18 mm. The drive 10 can therefore not only be used for locking and unlocking, but also for moving the window or door sash between different positions, such as a tilt, turn or closed position.

Fig. 3 shows a schematic perspective partial view of the sash profile 24 of a window according to the invention with a drive 10 placed on the sash profile 24 via at least one housing step Fig. 1 . The drive 10, as already stated, can be used not only for locking or unlocking at least one locking point, but in particular also for releasing or locking tilting, rotating and / or moving the window sash 24 into its closed position.

As in particular from the Fig. 3 and 4th As can be seen, the drive 10 can be at least partially integrated in the profile 24 of the sash or the frame of the window or door. The sash or frame profile 24 is provided with a recess 26 (cf. in particular Fig. 4 ), in the area of which or through which the drive 10 extends partially into a chamber of the sash or frame profile 24.

In the present case, the drive 10 is placed on the sash or frame profile 24 via at least one step provided on its housing 12, on which it is fixed, for example by screws or the like. The drive 10 sits in the present case partly in the chamber of the sash or frame profile 24 and partly in the rebate of the window.

A push rod or push rod element 20 is connected to the two ends 18 ′ of the elongated output element 18 of the drive 10 lying outside the drive housing 12 via a removable, exchangeable end piece 28.

As in particular from the Figures 5 and 6 As can be seen, a respective end piece 28 at the relevant end 18 'of the elongated output element 18 can be adjusted relative to the latter and can be fixed in different positions.

As in particular also based on the Figures 7 to 9 To see, a respective end piece 28 has an elongated shape, it being provided at one end with a pivot pin 32 that can be inserted into a corresponding opening 30 of the relevant end 18 'of the elongated output element 18 and at its opposite end with a threaded opening 34, in which can be screwed in a head screw 38 extending through an elongated hole 36 provided in the relevant end 18 'of the output element 18 to fix the end piece 28, which can be rotated relative to the relevant end of the output element 18 about a rotation axis defined by the pivot pin 32, in a respective rotational position.

In addition, a respective end piece 28 has, on its side opposite the pivot pin 32, a connection pin 40 aligned with the threaded opening 34 for connecting the push rod or the push rod element (20).

This connecting pin 40 can in particular have a different length in the various exchangeable end pieces 28.

The relevant end 18 'of the drive element 18 is shown in FIG Fig. 5 with a relatively shorter connecting pin 40, in which Fig. 7 End piece 28, shown again enlarged, provided, while the relevant end 18 'of the drive element 18 in the illustration according to Fig. 6 with a relatively longer connecting pin 40 in which Fig. 8 End piece 28 shown enlarged again is provided.

Fig. 9 shows an end 18 'of the output element 18 provided with a removable, exchangeable end piece 28 in a schematic plan view.

In the schematic partial representation of the output element 18 according to FIG Fig. 10 the toothing 22 and an end 18 ′ of the output element 18 provided with a removable, exchangeable end piece 28 can be seen.
