Description

The invention relates to an assembly of a door or a window of a building according to the preamble of claim 1.

Such an assembly includes a pivot member, a frame on which the pivot member is pivotally mounted about a pivot axis, and a motor drive device that acts to pivot the pivot member relative to the frame between the pivot member and the frame. The motor drive device is formed by a spindle drive with a spindle extending along a longitudinal axis and a spindle nut threadedly engaged with the spindle.

In the claimed swivel element is a door or a window of a building, so for example, a front door, an inner door or a building window. The drive device is used for motorized adjustment of the door or the window, wherein the drive device may have, for example, an electric motor which offset the spindle and the spindle nut of the spindle drive for pivoting the pivot member in a relative rotational movement to each other, so that the spindle nut rolls on the spindle and along the spindle is adjusted so as to transmit a torque for pivoting the door or the window relative to the frame.

The frame may accordingly be a door frame or a window frame.

The pivoting element usually serves to close an opening delimited by the frame. In this case, the pivoting element has a so-called secondary closing edge, by way of which the pivoting element is arranged pivotably about the pivot axis on the frame, and a main closing edge extending parallel to the secondary closing edge and remote from the pivoting axis. The secondary closing edge and the main closing edge are each assigned a counter-closing edge of the frame, which lies opposite the secondary closing edge or the main closing edge in a closed position of the pivoting element. (It should be noted that usually also the edges extending transversely to the main closing edge, for example at the top and bottom of a door leaf, are referred to as "secondary closing edges." If a secondary closing edge is mentioned in the context of the present text, this is intended to mean that of the main closing edge opposite edge of the pivot member may be designated, via which the pivot member about the pivot axis is pivotally mounted on the frame, unless expressly stated otherwise.)

The spindle drive is along the longitudinal axis, along which the spindle extends, fixedly disposed on the one of the pivot element and frame. This is to be understood that the spindle drive is arranged either on the pivoting element or on the frame, in such a way that the position of the longitudinal axis of the pivoting element or the frame is fixed. The spindle drive with the spindle extending along the longitudinal axis is thus not relative to the pivoting element (when it is fixedly arranged on the pivoting element) or relative to the frame (when it is fixedly arranged on the frame during pivotal movement of the pivoting element relative to the frame ) but remains fixed to the component to which it is arranged.

At one of the DE 102 13 427 A1 known drive for a wing of a door or a window, a drive device in the form of a spindle drive is provided in which a spindle is rotated for adjusting the wing, so that a standing with the spindle in threaded engagement spindle nut rolls on the spindle and along a longitudinal axis, along of which the spindle is extended on a frame is moved. The spindle nut is coupled to the wing via a lever and moves the wing as it moves along the spindle.

A disadvantage of the drive of DE 102 13 427 A1 is that a pivoting of a wing relative to a frame is possible only by a comparatively small angle. In addition, a lever is required, which protrudes from the frame and is coupled to the wing. This lever is clearly visible from the outside and also impedes if necessary with the wing open a penetration.

From the DE 197 56 496 C2 a revolving door drive with an electronic control is known in which a drive device is provided in the form of a spindle drive with a rotatable spindle and a spindle nut arranged on the spindle. In operation, the spindle nut moves a rack, which is in engagement with a drive shaft such that upon movement of the rack, the drive axle is set in a rotational movement over which a door can be pivoted.

From the DE 1 580 047 A a car door is known in which a rotatable spindle is in engagement with a spindle nut such that as a result of a rotational movement of the spindle, the spindle nut is moved longitudinally relative to the spindle. By moving the spindle nut, a linkage is driven to in this way, to pivot the vehicle door relative to a vehicle body.

Conventional drive devices for pivoting a pivoting element in the form of a door or a window of a building are designed as an attachment to a pivoting element or a frame or use at least visible levers which project from the pivoting element and from a plane in which the pivoting element extends protrude.

Object of the present invention is to provide an assembly of a door or a window of a building, which makes it possible to dispense with simple construction and reliable power transmission to clearly visible, protruding from the plane of a pivoting lever.

This object is achieved by an article having the features of claim 1.

Accordingly, the spindle drive has a along the longitudinal axis extending push rod, which, driven by a relative movement of the spindle to the spindle nut on one of the pivot member and frame along the longitudinal axis slidably and via a hingedly connected to the push rod hinge rod with the other of the pivot element and Frame is coupled to pivot by moving the push rod, the pivot member relative to the frame.

The present invention is based on the idea of using a spindle drive with a spindle extending along a longitudinal axis to drive a push rod, likewise extended along the longitudinal axis, for pivoting the pivoting element. The push rod is moved to pivot the pivot member along the longitudinal axis and is coupled via a link rod to the frame (when the spindle drive is disposed on the pivot member) or the pivot member (when the spindle drive is mounted to the frame).

Because the push rod is moved solely along the longitudinal axis and transmits the torque for pivoting the pivot member via the coupling of the pivot rod, the movement of the push rod in the plane of the pivot member (if the spindle drive is arranged on the pivot member) or within the frame (if Spindle drive is arranged on the frame), without a lever for transmitting power from the pivot member or the frame visibly protrudes outward.

As already stated, the drive device can be arranged in the form of the spindle drive on the pivoting element or on the frame. If the spindle drive is arranged on the pivoting element, the spindle drive can be arranged within a body of the pivoting element, for example within a door leaf. If the spindle drive is arranged on the frame, the spindle drive can extend within a frame section, ie within a door frame.

The longitudinal axis, along which the push rod extends, is advantageously directed perpendicular to the pivot axis about which the pivot member is pivotally mounted on the frame. This is true both for the case that the drive device is arranged in the form of the spindle drive on the pivot element, as well as for the case that the drive device is arranged on the frame. The longitudinal axis and thus the spindle of the spindle drive and the push rod thus extend perpendicular to the pivot axis, wherein in the arrangement of the spindle drive on the pivot member of the spindle drive at a pivoting of the pivot member is fixed in position with the pivot member mitverschwenkt in the arrangement of the spindle drive on the frame, however, at a Pivoting the pivot element remains fixed in position on the frame.

Preferably, the push rod acts via a secondary closing edge of the pivoting element, via which the pivoting element is pivotally arranged on the frame and which is directed parallel to the pivot axis, between the pivoting element and the frame. The torque for pivoting the pivot element is thus in the region of the minor closing edge - ie at the edge of the pivot member over which the pivot member is pivotally mounted on the frame - generated. Due to the fact that the push rod acts on the secondary closing edge, the free extension path over which the push rod and / or the connecting rod extend freely and visibly between the pivoting element and the frame is short, because in the region of the secondary closing edge the distance between the pivoting element and the Frame is small.

In a first variant, when the spindle drive is arranged on the pivoting element, the articulated rod can emerge from the pivoting element at the secondary closing edge and the pushrod can be supported in an articulated manner against the counter-closing edge of the frame opposite the secondary closing edge via the articulated rod. The push rod thus forms together with the articulated rod a lever mechanism between the minor closing edge of the pivoting element and the associated counter-closing edge of the frame, the is configured such that upon a displacement movement of the push rod along the longitudinal axis directed perpendicular to the pivot axis in the plane of the pivot member, a torque between the pivot member and the frame is effected, which leads to a pivoting of the pivot member relative to the frame. About the push rod and the pivot rod, the pivot member expresses so to speak from the frame and is pivoted due to the sliding movement of the push rod.

The articulated rod is in this case hingedly connected both to the counter-closing edge of the frame and to the push rod, wherein a suitable, optionally releasable coupling point for articulated connection with the articulated rod and at the counterclosing edge a suitable bearing for articulated arrangement of the articulated rod can be provided on the push rod.

In a second variant, the push rod, when the spindle drive is arranged on the frame, for applying a torque to the pivot member on a hinge, via which the pivot member is pivotally mounted on the frame, or a joint mounted on a hinge axis attack. The push rod can act on the pivot member via the link rod and a rotatably connected to the pivot member lever, wherein the hinge rod can be connected via a coupling point articulated to the push rod and a bearing point articulated to the lever. If the spindle drive is arranged within a frame section of the frame, a torque can be introduced into the pivot element by displacing the push rod along the longitudinal axis via the coupling of the articulated rod and the lever, this torque being exerted in the region of the hinge on the pivot element.

It is conceivable in this context to drive the pivoting element on one or more hinges, for which one or optionally also a plurality of spindle drives can be provided.

In a third variant, the push rod for exerting a torque on the pivot member also on a coupling linkage, via which the pivot member is pivotally coupled to the frame, attack. For this purpose, it is irrelevant whether the spindle drive is arranged on the pivoting element or the frame. By acting on the coupling linkage between the pivot member and the frame, the pivot member can be pivoted, wherein the pivoting does not take place directly by the action of the push rod directly between the pivot member and the frame, but by an indirect action on a coupling linkage.

This third variant comes into consideration, for example, for a motorized tilting of a tilting window.

About the motor drive device, the pivoting element can be pivoted in an electric motor driven manner relative to the frame. The motor drive device can in this case be designed so that it holds the pivoting element, so for example the door or the window of a building, in a closed position in which the limited by the frame opening by the pivot member in position. Basically, this could be dispensed with a separate Verrieglung, such as a door lock.

It is possible to design the spindle drive self-locking or not self-locking. If the spindle drive is designed to be self-locking, then the pivoting element can only be adjusted by an electric motor, driven by the motorized drive device, while manual adjustment by pressure or tension on the pivoting element is prevented by the self-locking spindle drive. On the other hand, if the spindle drive is not designed to be self-locking, an opening is possible by manually moving the pivoting element, for example the door or the window, when a sufficient force is applied, so that, for example, an emergency opening of a door or a window can be made.

In a development, the push rod may be coupled to a locking linkage for locking or unlocking the pivoting element relative to the frame in dependence on the position of the push rod. This is based on the idea not only to use the drive device for pivoting the pivot member, but also to use for (mechanical) controlling a Verrieglung the pivot member. About the Verrieglungsgestänge the lock is then actuated at the beginning of a pivoting movement to open the pivot member from a closed position so that the locking released and the pivot member is unlocked. Conversely, the locking is made when the push rod is moved to close the pivot member and the pivot member enters its closed position. In this way, a secure locking and thus a secure hold of the pivoting element is ensured in its closed position on the frame.

In principle, the drive device of the type mentioned here is different Embodiments of spindle drives conceivable and usable. In an advantageous embodiment, the spindle can be rotatably arranged on a housing of the spindle drive and are in operative connection with an electric motor for driving the spindle. The spindle nut is in this case non-rotatably arranged on a displaceably mounted on the housing tube of the push rod such that during a rotational movement of the spindle, the spindle nut is displaced together with the tube along the longitudinal axis relative to the housing. By rotating the spindle, driven by the electric motor, thus rolling the spindle nut (which is rotatably mounted on the tube of the push rod) on the spindle, so that due to the threaded engagement of the spindle nut with the spindle, the spindle nut along the longitudinal axis, along which the Spindle extends relative to the spindle is adjusted and thus the push rod is moved relative to the spindle.

The electric motor can in this case be arranged coaxially to the spindle in the housing, so that a slim, along the longitudinal axis extending design of the spindle drive results in low space requirements.

The push rod is advantageously biased by a spring relative to the housing. This can be achieved that (for example, in a non-self-locking design of the spindle drive), the pivoting element is automatically pivoted back into a starting position after pivoting. For example, the spring may bias the push rod toward an extended position in which the push rod is extended out of the housing on which the spindle is located. For example, if a weighting force of a pivoting element in the form of a tilting window acts in the direction of retraction on the pushrod, this weighting force can be compensated by the biasing spring so that the tilting window can be securely supported and held by the spindle drive.

Act no significant weight forces around the pivot axis on the pivot member and a bias in a certain position of the pivot member is not desirable, so can be dispensed with the biasing spring.

1 and 2 show in schematic views a first embodiment of an assembly consisting of a pivoting element in the form of a pivotally mounted on a frame 2 arranged door 1 and one at the door 1 arranged drive device 3 for motorized pivoting of the door 1 relative to the frame 2 is formed.

For example, the door may be an outside door or an inside door of a building, one through the frame 2 limited door opening in a closed position (shown schematically in FIG 1 ) closes.

The drive device 3 is designed in the manner of a spindle drive and, in the in 1 and 2 illustrated embodiment, on the pivoting element in the form of the door 1 arranged. The drive device 3 is here in or on a body 13 in the form of a door leaf of the door 1 arranged, for example in the body 13 let in, and has a push rod 31 on, via a spindle and a spindle nut of the drive device 3 for pivoting the door 1 is driven, as will be explained in detail below.

The drive device 3 is about a camp 300 and a side bearing 302 Stable at the door 1 arranged. The push rod 31 is in this case along a longitudinal axis L extends and along this longitudinal axis L on the door 1 displaceable and has a coupling point 301 on, to which a joint rod 303 is connected. The articulated rod 303 is at her the push rod 31 opposite end to a warehouse 304 at a counter closing edge 20 supported by the frame, over which also the door 1 over one or more hinges 10 is arranged pivotably about a pivot axis S.

The counter-closing edge 20 of the frame 2 is a minor closing edge 14 the door 1 assigned and parallel to this secondary closing edge 14 extends. The secondary closing edge 14 extends along a vertical direction Z, and over the minor closing edge 14 the door is pivotable about the pivot axis S on the frame 2 arranged. The distance from the pivot axis S, parallel to the secondary closing edge 14 directed edge 15 the door 1 is referred to as the main closing edge and is another counter-closing edge 21 on the frame 2 assigned.

For pivoting the door 1 relative to the frame 2 becomes the push rod 31 in an adjustment direction V from the drive device 3 extended in the form of the spindle drive, so that on the coupling by means of the articulated rod 303 the door 1 at the counter-closing edge 20 is pressed and a torque about the pivot axis S on the door 1 to open the door 1 in an opening direction O (see 2 ) is exercised.

The movement of the push rod 31 takes place along the longitudinal axis L and thus (at least for the most part) within the body 13 the door 1 , where the articulated rod 303 at the counter-closing edge 20 facing secondary closing edge 14 out of the body 13 exit. The open road, along which the articulated rod 303 and / or the push rod 31 free between the door 1 and the frame 2 runs, is thus short, so the articulated rod 303 and / or the push rod 31 hardly visible from the outside.

In addition to the drive device 3 can also have control electronics within the body 13 be arranged in the form of the door leaf, so that neither the drive device 3 still the control electronics are visible from the outside.

It is also conceivable, a control electronics in or on the frame 2 to arrange.

In the 1 and 2 illustrated arrangement of the drive device 3 has the further advantage that pivoting the door 1 to a large opening angle is possible, in particular an opening angle greater than 90 °.

Another embodiment show 3A and 3B , Components of the same function are intended, where appropriate, as well as in the following further embodiments with the same reference numerals as previously referred to.

In the embodiment according to 3A and 3B is a drive device 3 in the form of a spindle drive on a frame 2 housed, where a door 1 about a pivot axis S via a hinge 10 is pivotally mounted, and this within a frame section 23 edged in the form of a door frame. The drive device 3 has a push rod 31 on that over a coupling point 301 with a joint rod 303 coupled and slidable along a longitudinal axis L.

In the embodiment according to 3A and 3B is the articulated rod 303 about a depository 303A with a linkage 305 connected via a lever 306 on the pivoting element in the form of the door 1 attacks. About the linkage 305 is the articulated rod 303 with the lever 306 coupled, with the lever 306 rotatably with the pivoting element in the form of the door 1 is connected, so that an adjusting movement of the push rod 31 in a pivoting movement of the door 1 is implemented. The lever 306 is at the bottom of the linkage 305 arranged and engages in the area of a hinge 10 at the door 1 at.

In operation, the push rod 31 , driven by the drive device 3 , proceed along the longitudinal axis L (adjustment direction V), so that over the joint rod 303 and the lever 306 a torque on the door 1 exercised and this relative to the frame 2 is pivoted. The arrangement is such that upon retraction of the push rod 31 contrary to the adjustment direction V the door 1 in the opening direction O is opened by the lever 306 towards the drive device 3 is pulled. The closing of the door 1 done in reverse by pushing the push rod 31 in the Adjustment direction V from the drive device 3 is extended.

In the embodiment according to 4A and 4B is, in contrast to the embodiment according to 3A and 3B , the linkage 305 through an additional pivot 307 in the form of a bearing on the door frame 2 stored. This results in a reversal of the direction of movement of the drive movement, compared with the embodiment according to 3A and 3B (related to the movement of the door 1 ), and thus possibly a better utilization of power.

The linkage 305 is articulated at its upper end with the articulated rod 303 and at its lower end hinged to the lever 306 connected.

During operation, the push rod 31 extended in the adjustment direction V, so the linkage 305 around the fulcrum 307 tilted. The section of the linkage tilts 305 above the fulcrum 307 in the pivoting direction A1 (in the view according to FIG 4A to the left), the section below the fulcrum 307 however, in the pivoting A2 (in the view according to 4A to the right), so the lever 306 in the pivoting direction A3 (see 4B ) in the direction of opening the door 1 is moved.

An extension of the push rod 31 thus causes an opening of the door 1 , Will, however, the push rod 31 retracted, so will the door 1 closed by the lever 306 pivoted back against the pivoting direction A3. A train on the push rod 31 in the direction of retraction thus causes an opening, a pressure on the push rod, however, a closing, wherein the push rod 31 may additionally be elastically biased in the direction of extension, so that the closing movement supports resilient or, if appropriate, can be done automatically after opening.

About the linkage 305 and the pivot point 307 Optionally, a transmission or reduction of the drive movement of the push rod 31 in the pivoting movement of the lever 306 be set.

The embodiments described above can be used for exterior doors and interior doors in buildings. In principle, especially when used in an inner door, this can also be dispensed with a door lock. The inner door is then only due to the holding forces of the drive device 3 held in its closed position.

It is conceivable here that the drive device 3 is designed self-locking in the form of the spindle drive, so that opening the door 1 is only possible by electric motor, driven by the drive device 3 ,

It is also conceivable, the drive device 3 not self-locking, so also manually by moving the door 1 an opening of the door 1 , for example, for the purpose of an emergency opening, is possible.

Optionally, it is also possible to additionally provide a further brake, the unwanted adjustment of the door 1 with force on the door 1 prevented, especially at a not by the drive device 3 effected, at the door 1 attacking force. For this purpose, for example, a wrap spring brake can be used, as it is known for example from power window drives from automotive engineering. Such a loop spring serves as a load torque lock such that a drive side by the drive device 3 initiated torque is transmitted and to pivot the door 1 leads, a torque introduced on the output side, so an output side to the door 1 applied torque, however, is locked, so that a driven-side torque does not cause an adjustment of the door 1 can lead.

At the in 5 illustrated embodiment is a drive device 3 on a frame 2 ' a pivoting element in the form of a window 1' used in a building. The drive device 3 is on a frame section of the frame 2 ' arranged and acts, according to the basis of 3A and 3B described manner, on the window 1' to pan the window 1' about a pivot axis S a. The operation of the drive device 3 is identical as described above, so that the comments on the embodiment according to 3A and 3B should be referenced.

In a comparison with the embodiment according to 5 only slightly modified embodiment, shown in FIG 6 , the drive device acts 3 over the push rod 31 and the articulated rod 303 on a coupling linkage 11 for coupling the window 1' with the frame 2 ' one. The articulated rod 303 stands for this with a lever 110 of the coupling linkage 11 in operative connection such that upon extension of the push rod 31 in the adjustment direction V the window 1' about the pivot axis S relative to the frame 2 ' to open the window 1' is tilted. The coupling linkage 11 serves here in a conventional manner for guiding the tilting movement of the window 1' and to limit this tilting movement to one defined opening angle in a tilted position of the window 1' set and the window 1' to keep in this tilted position.

In a further embodiment, shown in FIG 7 , is - in development of the embodiment according to 5 - In addition, a locking rod 12 provided that the drive device 3 with a lock 122 coupled. The locking linkage 12 has a connecting rod for this purpose 120 on, a long hole 308 at the joint rod 303 reaches through, with the push rod 31 is connected and at her the slot 308 opposite end with a pivotable about a pivot point D rocker arm 121 is coupled.

The slot 308 is on the articulated rod 303 trained, and the articulated rod 303 is over the slot 308 with the push rod 31 coupled. The push rod 31 is directly with the connecting rod 120 connected such that upon movement of the push rod 31 in the direction of opening the window 1' from a closed position, the connecting rod 120 for unlocking the lock 122 is moved, but the articulated rod 303 initially not moved. Only after a predetermined displacement of the push rod 31 and a complete unlocking of the lock 122 becomes the articulated rod 303 moved to the window 1' to pivot.

The operation of the drive device 3 to open the window 1' is basically as above based on 5 explained. In addition, however, upon extension of the push rod 31 in the adjustment direction V for tilting the window 1' about the pivot axis S by coupling over the slot 308 also the connecting rod 120 of the locking linkage 12 moved so that over the rocker arm 121 the lock 122 brought from a locked position and the window 1' is unlocked. The coupling between the locking linkage 12 and the push rod 31 or the articulated rod 303 is such that the lock 122 first it is solved, before there is a tilting of the window 1' comes, so the latch 122 one by the drive device 3 caused tilting of the window 1' not disabled.

Will the window 1' reversed by retracting the push rod 31 brought against the adjustment direction V back to its closed position, so when it reaches the closed position, the lock 122 brought back into its locking position by the coupling linkage 12 is confirmed accordingly.

A use of a drive device 3 in combination with a locking linkage 12 the in 7 illustrated type is basically also conceivable in the other embodiments described above. Generally, the movement of the push rod 31 be used to mechanically control a lock for providing an additional backup for a pivot member, so that locking or unlocking takes place synchronously with the motor-driven pivoting movement.

8A and 8B show a concrete embodiment of a drive device 3 in the form of a spindle drive. The drive device 3 has a spindle 32 on, which extends along a longitudinal axis L, rotatably on a housing 30 is arranged and with a gear 34 and an electric motor 35 communicates.

The spindle 32 has on its outer circumferential surface on an external thread, with an internal thread on a bore 313 a spindle nut 310 engaged. The spindle nut 310 is rotatably on an (inner) pipe of a push rod 31 held over one of the spindle nut 310 opposite end face 314 in a cladding tube 312 is stored. The cladding tube 312 is on the case 30 slidably mounted (but non-rotatable) along the longitudinal axis L, so that over the cladding tube 312 also the tube 311 on the housing 30 is guided.

At the front 314 the push rod 31 is a coupling point 301 for coupling the push rod 31 with the articulated rod 303 (see embodiments according to 1 to 7 ) arranged.

During operation of the drive device 3 the electric motor displaces 35 over the transmission 34 the spindle 32 in a rotational movement about the longitudinal axis L. Due to the threaded engagement of the spindle nut 310 with the spindle 32 and the fixed arrangement of the spindle nut 310 at the push rod 31 rolls the spindle nut 310 at the spindle 32 off, leaving the spindle nut 310 along the longitudinal axis L relative to the spindle 32 is adjusted and together with the spindle nut 310 the pipe 311 and the cladding tube 312 be moved and thus the entire push rod 31 is moved.

8A shows here the drive device 3 in an extended position, wherein the spindle nut 310 to a gearbox 34 opposite end of the spindle 32 procedure is. 8B whereas the drive device shows 3 in a retracted position, where the spindle nut 310 the transmission 34 facing the end of the spindle 32 is approximated.

The push rod 31 is about a spring 33 in the form of a compression spring against the housing 30 preloaded and to a support 36 at the housing 30 supported. The bias is carried out in the direction of the extended position (see 8A ), so the spring 33 at a retraction of the push rod 31 opposite to the adjustment direction V is stretched to pressure, as in 8B is shown.

By means of the spring 33 can, in particular in a non-self-locking embodiment of the drive device 3 , a Rückverstellen the drive device 3 be effected in the direction of a starting position, so that, for example, a pivoting element by the action of the spring 33 automatically adjusted to an initial position, for example, a closed position after an adjustment.

It is also possible by means of the spring 33 To compensate for weight forces acting on a pivoting element. This can be particularly advantageous if (as in a tilt window of in 5 shown type) acting on the pivot element weight forces on the drive device 3 Act. These weight forces can be compensated by a suitable bias, so that it can not come to an automatic adjustment of the pivoting element due to weight forces.

Optionally, on the spring 33 be waived, especially if a bias in a certain starting position is not desired or if no (significant) weight forces acting on a pivoting element, which must be compensated by a spring (as for example in a vertically directed pivot axis of the pivot member, for example a door of in 1 the kind shown is the case).

A modified embodiment of a drive device 3 in which no spring for biasing a push rod 31 opposite a housing 30 is provided shows 9 , In the modified embodiment, as in the embodiment according to FIG 8A and 8B , a spindle 32 rotatably mounted and stands with a gearbox 34 and an electric motor 35 engaged. During operation of the drive device 3 becomes the spindle 32 in a rotational movement such that one with an external thread of the spindle 32 engaged, a bore 313 having spindle nut 310 at the spindle 32 unrolls and along an adjustment V axially relative to the spindle 32 is moved.

With the spindle nut 310 is a pipe 311 coupled, on the front side 314 a coupling point 301 for connection to a connecting rod 303 (see, for example 1 ) is arranged.

The pipe 311 the push rod 31 is axially displaceable on the housing 30 stored, but not a spring against the housing 30 biased. Also, an outer cladding tube is not present, so that there is an overall simple structure.

The operation of the drive device is otherwise identical as based on 8A and 8B described, so that reference should be made to the preceding embodiments.

The idea underlying the invention is not limited to the above-described embodiments, but can also be realized in fundamentally different embodiments. In particular, other designs of spindle drives are possible in principle, as long as they allow a displacement of a push rod along a longitudinal axis, and other arrangements of windows, doors or other pivotal elements of a building are possible.
