Description

Closing device of a building opening

description

The invention relates to a closing device of a building opening according to the preamble of claim 1.

Such a closing device comprises a pivoting wing, for example a window or door leaf, and a frame which holds the pivoting wing pivotally. The frame has a hinge-side frame portion to which the swing-wing is pivotable about a pivot axis, an opening-side frame portion opposite to the hinge-side frame portion, and a transverse portion extended between the hinge-side frame portion and the opening-side frame portion.

The hinge-side frame portion is associated with the edge of the swing-wing about which the swing-wing is pivoted to open or close the building opening. The pivoting wing can in this case be arranged pivotably on one or more hinges on the hinge-side frame section. It is also conceivable that there is no direct hinge connection between the pivoting wing and the hinge-side frame section, for example by the pivoting wing hingedly connected to adjoining the hinge-side frame section transverse sections.

Such a closing device may be formed, for example, by a window or a door or a hinged flap flap device of a building.

The closing device comprises a motor drive device which acts to pivot the pivoting leaf between the pivoting wing and the frame and has a spindle drive with a spindle extending along a longitudinal axis and a spindle nut threadably engaged with the spindle and movable along the longitudinal axis.

In one known from DE 102 13 427 A1 drive for a wing of a door or window, a drive device is provided in the form of a spindle drive in which a spindle is rotated for adjusting the wing, so that a standing with the spindle in threaded engagement with the spindle nut unwinds the spindle and along a longitudinal axis along which the spindle is mounted 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 the wing relative to the 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, if necessary, hinders access when the sash is open.

From DE 197 56 496 C2 a rotary 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, via which a door can be pivoted. Conventional drive devices for pivoting a pivoting door in the form of a door or a window of a building are designed as an attachment to a pivoting wing or a frame or use visible levers of the Swinging wings protrude and protrude from a plane in which the pivoting wing extends.

Object of the present invention is to provide a closing device for a building opening, which makes it possible to dispense with simple construction and reliable power transmission to clearly visible, protruding from the plane of a swing wing lever.

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

Accordingly, a coupling element rotatable about an axis of rotation is provided, which is arranged on a side of the transverse section facing the pivoting wing or on a side of the pivoting wing facing the transverse section and connected to a pivoting rod coupled to the spindle nut in such a way that the coupling element moves when the spindle nut is moved is rotated about the axis of rotation for pivoting the pivoting wing.

The present invention is based on the idea to introduce an adjusting force for pivoting the pivoting leaf via a coupling element in the pivoting wing, which is rotatable about an axis of rotation by means of the spindle drive of the drive device. The drive device can in principle be arranged on the frame or on the pivoting wing. The coupling element may in this case - depending on the arrangement of the drive device on the frame or the pivoting leaf - be arranged on the transverse section of the frame or on the pivoting wing.

If the drive device is arranged on the frame, the coupling element is advantageously located on the transverse section of the frame, namely on a side of the transverse section facing the pivoting wing. By way of example, the transverse section can be an upper frame section which extends transversely between the hinge-side frame section and the opening-side frame section. In this case, the coupling element points from a lower side of the frame section facing the pivoting wing toward the pivoting wing.

On the other hand, if the drive device is arranged on the pivoting wing, then the coupling element is located on the side of the frame which faces the transverse section of the frame Swinging wing, that is on an upper side of the pivoting wing, when the transverse section forms an upper frame section.

Due to the fact that the introduction of force into the pivoting wing takes place via the coupling element, complicated lever mechanisms can be dispensed with. The pivoting of the pivoting wing can be effected in a simple manner by turning the coupling element and direct introduction of force into the pivoting wing, so that parts visible to the outside can be dispensed with. The drive device is arranged in a preferred embodiment with respect to the longitudinal axis positionally fixed to the transverse portion of the frame. This is to be understood that the arrangement of the drive device at the transverse portion of the frame with respect to the position of the longitudinal axis is fixed and unchanging. In operation, only the spindle nut is moved along the longitudinal axis and rotated via the hinge rod, the coupling element to initiate an adjusting force in the pivoting wing and to pivot the pivoting wing.

The arrangement of the drive device on the transverse section of the frame has the advantage that the drive device can be mounted completely hidden within the transverse section and thus outwardly invisible. The transverse section can for this purpose have a cavity in which the drive device is mounted with its spindle drive. Only the coupling element extends in this case over the side facing the swing wing side of the transverse portion to the outside and allows the production of an operative connection of the swing wing with the drive device.

To produce the operative connection of the coupling element with the pivoting wing (in the arrangement of the drive device on the transverse section) or the frame (in the arrangement of the drive device on the pivoting wing), the coupling element is advantageously connected to a lever. Upon rotation of the coupling element in this case the lever is pivoted about the axis of rotation and exerted in this way an adjusting force on the swing-wing.

For coupling the lever with the pivoting wing (in the arrangement of the coupling element on the transverse portion of the frame) or the frame (in the arrangement of the coupling element on the side facing the transverse portion of the pivoting wing) different variants are conceivable. On the one hand, it is conceivable to rigidly connect the lever to the pivoting wing (in the case of an arrangement of the coupling element on the side of the transverse section facing the pivoting wing) or the transverse section (in the case of an arrangement of the coupling element on the side of the pivoting wing facing the transverse section), so that a rotation of the Coupling element is implemented in a direct manner in a pivoting of the pivoting wing relative to the frame. This is particularly considered when the pivot axis of the pivoting wing and the axis of rotation of the coupling element collinear collinear. The lever can be screwed in this case as an additional component with the pivoting wing or the transverse section. It is also conceivable that the lever is formed integrally with the pivoting wing or with the transverse section and thus by the pivoting wing or the transverse section itself.

On the other hand, it is also conceivable to guide the lever in a sliding manner on the pivoting wing or the transverse section of the frame. For this purpose, the lever with a coupling element facing away from the end of a guide portion of the pivoting wing (when the coupling element is arranged on the side facing the pivoting wing side of the transverse portion) or the transverse portion (when the coupling element is arranged on the transverse portion facing side of the pivoting wing) slidably guided be. Upon rotation of the coupling element, the lever is pivoted together with the coupling element, in this way introduces an adjusting force into the pivoting wing and slides during pivoting of the pivoting blade along the guide section to - when the axis of rotation of the coupling element and the pivot axis of the pivoting wing fall apart - a relative movement between the lever and the guide section.

The coupling of the coupling element with the lever can be done in different ways. For example, may be provided between the coupling element and the lever, a slip clutch which is configured such that in normal motor operation, an adjusting force can be introduced from the drive device via the coupling element in the swing wing. However, if a counterforce applied to the swing leaf, for example manually applied or introduced via an obstacle, is greater than a predetermined limit, then the slip clutch may allow a relative movement between the coupling element and the lever so that the swing wing is adjusted relative to the coupling element and thus to the frame becomes. In this way, for example, a manual closing when the closing device is open, for example, when the window or door open, are possible. Or a further movement of the pivoting wing when opening or closing can be prevented if the swinging wing strikes an obstacle and therefore should not be moved further (in this case, the limit can be adjusted, for example, to a maximum permissible pinching force).

The slip clutch can be realized for example by a connection between a pin and a socket. For example, may be formed on the lever, a pin which engages rubbing in the coupling element designed as a bushing. The frictional engagement is in this case such that in a normal adjustment of the swing wing, motor driven by the drive device, adjusting forces can be introduced into the swing vanes, on exceeding a predetermined limit force, however, a relative movement between the pin and the sleeve formed as a coupling element is possible , so the clutch can slip through.

A slip clutch makes sense especially when the spindle drive of the drive device is designed to be self-locking and thus an external force acting on the swing wing is inhibited by the drive device. If the drive device is not designed to be self-locking, then basically a slip clutch can also be dispensed with.

Instead of a slip clutch, the coupling element can also be connected via a meshing engagement and thus form-fitting manner with a pinion of the lever. Due to the positive engagement between the coupling element and the pinion adjusting forces can be introduced into the pivot wing in an efficient, slip-free manner, preferably the engagement can be solvable to release the swing wing of the frame or to effect a reversal of direction for the motorized adjustment.

The latter is particularly useful when the pivoting wing, depending on the coupling of the coupling element with the lever, from a closed position in a first opening direction or in a first opening direction opposite, second opening direction should be pivotally to basically open the swing leaf in different To allow opening directions. For this purpose, the coupling element can be connected in different positions with the lever, for example, by the coupling element is brought in different positions in meshing engagement with the pinion of the lever. Depending on the position of the coupling element to the lever can then, driven by the drive device, the coupling element are moved from a starting position with the swing wing closed in a first direction of rotation to open in the first opening direction or in a second direction of rotation to open in the second opening direction.

The axis of rotation of the coupling element and the pivot axis of the pivoting wing may fall apart. In an advantageous embodiment, however, the axis of rotation of the coupling element and the pivot axis of the pivoting wing are collinear and thus coincide, which allows a direct pivoting of the pivoting wing with a 1: 1 translation upon rotation of the coupling element. In principle, different embodiments of spindle drives are conceivable and usable for the drive device of the type mentioned here. 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 push rod such that during a rotational movement of the spindle, the spindle nut is displaced together with the push rod 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 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 is moved relative to the spindle 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. In this way it can be achieved that (for example, in a non-self-locking embodiment of the spindle drive), the pivoting wing 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 from the housing on which the spindle is arranged. If, for example, a weight force of a pivoting wing in the form of a tilting window acts in the direction of retraction onto the pushrod, then 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 appreciable weight forces around the pivot axis on the swing wing and a bias in a certain position of the swing wing is not desirable, so can be dispensed with the biasing spring.

In another embodiment, the drive device may also comprise a spindle nut, which is guided longitudinally on a housing and has a pin, via which the spindle nut is coupled to the articulated rod. For articulated coupling of the spindle nut with the articulated rod of the pin can in this case for example engage in a slot of the articulated rod, wherein the pin is preferably guided over a guide portion on a parallel to the longitudinal axis of the spindle guideway and thus rotatably holding the spindle nut at a longitudinal adjustment. The spindle nut is thus rotatably guided on the engagement of the guide portion of the pin in the guide track, which is for example on a fastening element, via which the drive device is fixed to the frame or the swing wing, so that upon rotation of the spindle, the spindle nut unwinds the spindle and is moved longitudinally to the spindle. Characterized in that the spindle nut engages over the pin in a slot of the joint rod and thus is connected via the pin articulated to the articulated rod, eliminates an additional longitudinally along the spindle to be adjusted push rod. Adjusting forces are instead introduced directly via the spindle nut in the articulated rod. Because no push rod has to be moved out or retracted to adjust the articulated rod, the installation space to be provided for the drive device can be reduced. This results in an overall compact design and arrangement of the drive device on the frame or the swing wing.

In an advantageous embodiment, a spring may be provided which acts between the spindle nut and the housing and provides a bias to cause, for example, a return adjustment of the spindle nut after a successful adjustment, for example, after opening the pivoting blade. The spring can For example, be designed as a compression spring and, for example, tense when the spindle nut is adjusted to open the swing leaf. After the opening can then take place due to the spring forces provided by the tensioned spring forces an automatic backward movement of the spindle nut, for which purpose the spindle drive is preferably not designed to be self-locking.

The spring may for example be longitudinally along the spindle and engage around the spindle. The spring is in this case on the one hand on the spindle nut and on the other hand, for example, at one end of the housing, on which a gear and / or an electric motor for driving the spindle are arranged, supported.

On the sides of the spindle nut, the spring may for example be supported on a bush fastened to the spindle nut. The bushing may for example be attached as an additional part of the spindle nut and for this purpose have a collar which engages positively in an associated recess of the spindle nut. The sleeve may in this case be held against rotation on the spindle nut, wherein it is conceivable that the spindle nut made of plastic and the sleeve are made of metal, so that on the metal bushing a reliable, firm attachment for the spring is provided on the spindle nut.

In an advantageous embodiment, the drive device can be fastened to a fastening element via a fastening angle and to the transverse section of the frame or to the pivoting wing via the fastening element. The mounting bracket, for example, form a bearing for rotatable mounting of the coupling element. The coupling element can in this case be connected to the articulated rod, for example, so that the coupling element is rotated by adjusting the spindle nut and the action of the spindle nut directly on the articulated rod. The slot in which engages the pin of the spindle nut, this serves to implement the Längsverstellbewegung the spindle nut in a pivoting movement of the articulated rod, so that in a longitudinal movement of the spindle nut, driven by the spindle pivots the pivot rod and thereby rotates the coupling element at its bearing point becomes. The pivoting wing is then moved relative to the frame for opening or closing via the coupling element.

Fig. 1 to 6 show a first embodiment of a closing device of a building in the form of a building door 1, which has a pivotally mounted on a frame 10 pivoting wings in the form of a door leaf 2. The door leaf 2 is pivotable about a pivot axis A, wherein the pivot axis A is associated with a hinge-side frame portion 101 of the frame 10 and the door leaf 2 to the hinge-side frame portion 101 is pivotable. The hinge-side frame portion 101 is opposed to an opening-side frame portion 100, which is associated with a main closing edge 23 of the door leaf 2. The hinge-side frame portion 101 and the opening-side frame portion 100 are connected to each other by a transverse portion 102 extending between the hinge-side frame portion 101 and the opening-side frame portion 100 forming an upper frame portion of the frame 10. On the door 2, a handle 21 is provided, which allows a manual pivoting of the door leaf 2.

At the upper transverse portion 102 of the frame 10, a drive device 3 for motorized driving of the pivoting movement of the door leaf 2 is arranged. The drive device 3 has - as will be explained below with reference to the embodiments of FIGS. 14A, 14B and FIG. 15 - a spindle drive with a longitudinal axis L extended along a spindle 32 (see, for example, Fig. 14A) and one with the spindle 32nd threadedly engaged spindle nut 310. The spindle 32 is rotatable about the longitudinal axis L. The spindle nut 310 is coupled to a push rod 31, which is guided on a housing 30 and a guide bushing 38. During a rotational movement of the spindle 32 about the longitudinal axis L, the spindle nut 310 rolls on the spindle 32 such that the spindle nut 310 moves in a longitudinal movement along an adjustment direction V (see FIG. 2) pointing parallel to the longitudinal axis L and thereby the push rod 31 along the adjustment direction V is moved.

The push rod 31 is pivotally connected via a coupling point 301 with a hinge rod 303, as shown for example in Fig. 2. The hinge rod 303 is connected via a bearing 303A with a lever 306, which is integrally formed with a coupling member 307 in the form of a socket.

The coupling element 307 is arranged so as to be rotatable about the transverse section 102 of the frame 10 about an axis of rotation S and accessible via a recess 103 (see FIG. 3) via a side 102A of the transverse section 102 facing the door leaf 2.

In the coupling element 307 engages a pin 308, which is integrally formed with a lever 309. The lever 309 is slidably guided with one end 309A on a guide section 220 on a side 22 of the door leaf 2 facing the transverse section 102. The guide portion 220 is in the form of an elongated recess and serves as a guide for a guide pin formed on the end 309A of the lever 309.

To open the door leaf 2 in an opening direction O, shown in FIGS. 5 and 6, the push rod 31 is moved in an adjustment direction V1 and thus introduced by means of the hinge rod 303, an adjusting force in the lever 306 and above in the coupling element 307. As a result of the longitudinal movement of the push rod 31 in the adjustment direction V1 the coupling element 307 is rotated in a direction of rotation D1, and together with the coupling element 307 the lever 309 pivots.

Adjusting forces are thus introduced into the door leaf 2 via the lever 309, which effect an opening of the door leaf 2 in the opening direction O by pivoting about the pivot axis A assigned to the door leaf 2. Although the axis of rotation S of the coupling element 307 and the pivot axis A of the door leaf 2 are parallel to each other, but eccentric fall apart, the lever 309 is guided over its end 309A on the guide portion 220, so that upon pivoting of the door leaf 2, the end 309A of the lever 309 can slide in the guide portion 220 and thus is movable relative to the door leaf 2, so that a change in distance during pivoting of the door leaf 2 can be compensated.

Fig. 5 shows the building door 1 when opening the door leaf 2. Fig. 6 shows the building door 1 at maximum open door 2. In this maximum open position, the end 309A of the lever 309 is located at one end of the guide portion 220, so that another Swiveling the door leaf 2 is not possible.

When the coupling element 307 is rotated, the lever 309 is rotated about the rotation axis S together with the coupling element 307. The coupling between the lever 309 and the coupling element 307 in this case takes place via the pin 308 formed on the lever 309, which engages in an inner, central bore of the coupling element 307 designed as a socket. The engagement of the pin 308 in the coupling member 307 realized a slip clutch, which is designed so that adjusting forces for a normal adjustment of the door leaf 2, driven by the motor drive device 3, can be introduced into the door 2 in a slip-free manner, at the output side introduction of Adjusting forces in the door 2 not on the drive device 3 but a relative movement between the coupling element 307 and the pin 308 is possible - at least when the introduced, output-side adjusting forces exceed a predetermined limit.

In this way it is possible, for example, to manually pivot the door leaf 2 by applying sufficiently large adjusting forces when the door leaf 2 is open. By means of the slip clutch can also be realized an anti-trap, which limits the force acting on the door leaf 2 forces to a maximum permissible pinching force by setting the limit and slipping the slip clutch between the coupling member 307 and the pin 308 allows when pivoting the door leaf 2 is obstructed when opening or closing by an object.

The provision of such a slip clutch is advantageous if the drive device 3 is self-locking with its spindle drive and thus the output side acting on the door leaf 2 adjusting forces are inhibited by the drive device 3.

If the drive device 3 is not designed to be self-locking, it is basically possible to dispense with a slip clutch. In this case, for example, a manual adjustment of the door leaf 2 is possible in that over the lever 306 and the hinge rod 303, the manual forces are transmitted to the spindle nut and thereby a relative movement between the spindle nut and the spindle is effected. The coupling element 307 is accessible from the (sub) side of the transverse section 102 facing the door leaf 2. The operative connection between the drive device 3 and the door leaf 2 is thus produced via the door leaf 2 facing side 102 A of the transverse portion 102, wherein via the lever 309, a coupling is provided, which is largely invisible to a user from the outside.

7 to 13C show a further embodiment of a closing device in the form of a building door 1, in which a pivoting wing 2 is arranged pivotably about a pivot axis S on a frame 10. In the embodiment according to FIGS. 7 to 13A-13C, a drive device 3 is arranged within an upper transverse section 102, wherein the transverse section 102 can completely receive and enclose the drive device 3 and thus cover it to the outside. The embodiment is of its basic operation forth equal to the embodiment of FIG. 1 to 6, so that reference is made to the above explanations and will be discussed below in particular to the differences. components the same function should be denoted by the same reference numerals, as far as this is expedient.

In contrast to the exemplary embodiment according to FIGS. 1 to 6, in the exemplary embodiment according to FIGS. 7 to 13A-13C, the pivot axis A of the door leaf 2 and the axis of rotation S of the coupling element 307 collinearly coincide (see, for example, FIG. 9). This makes it possible to connect a lever 309 'fixedly, for example by screwing, to the upper side 22 of the pivoting wing 2, so that adjusting forces are introduced directly into the door leaf 2 via the coupling element 307 and lead to a pivoting of the door leaf 2 about its pivot axis S. ,

In the embodiment according to FIGS. 7 to 13A-13C, the lever 309 'is coupled via a pinion 308' to the coupling element 307 which in turn is designed as a socket, wherein the coupling element 307 carries an internal toothing and, accordingly, a form-locking connection between the coupling element 307 and the pinion 308 'exists. In operation, a rotational movement of the coupling element 307 is thus transmitted in a slip-free, positive-locking manner to the pinion 308 'and, moreover, to the lever 309' and the door leaf 2. The building door 1 can be operated in two different modes, which differ by the relative position of the coupling element 307 to the pinion 308 '. If the coupling element 307 is in an initial position with the door leaf 2 closed in the position shown in FIG. 10, the coupling element 307 can be rotated in the direction of rotation D1 by moving the push rod 31 in the adjustment direction V1 in order to move the door leaf 2 in a first opening direction 01 to open. On the other hand, if the coupling element 307 is in the starting position with the door closed 2 in the position shown in FIG. 11 to the pinion 308 ', the coupling element 307 can be displaced by displacing the push rod 31 in the second adjustment direction V2 opposite the first adjustment direction V1 the direction of rotation D2 are rotated in order to pivot the door leaf 2 in the second opening direction 02, which is opposite to the first opening direction 01.

In the case of the building door 1, pivoting of the door leaf 2 into two different opening directions 01, 02 is thus possible without fundamental structural modification of the drive device 3, for which purpose only the coupling element 307 is in the starting position in FIG. 10 or FIG shown Way with the pinion 308 'engage. The opening direction 01, 02 can be changed by moving the coupling element 307 relative to the pinion 308 ', so that, depending on the position of the coupling element 307 to the pinion 308', the door leaf 2 can be opened selectively in one or the other opening direction 01, 02 can be.

The operation of the drive device 3 for opening and closing the door leaf 2 is basically independent of whether the door should be open in the first opening direction 01 or in the second opening direction 02. If the door leaf 2 is to be opened in the first opening direction 01, opening is effected by introducing tensile forces in the first adjustment direction V1 into the lever 306 (see FIG. 10), whereas closing is effected by introducing pressure forces. If the door leaf 2 is to be opened in the opposite, second opening direction 02, then this is exactly the opposite: to open pressure forces are introduced into the lever 306, while being pulled to the lever 306 to close (see Fig. 1 1).

This is also apparent from the views of FIGS. 12A-12C and 13A-13C, which illustrate the movement sequence when opening in the first opening direction 01 (FIGS. 12A-12C) and in the second opening direction 02 (FIGS. 13A-13C).

When opening in the first opening direction 01, the coupling element 307 is rotated in the first direction D1 by moving the push rod 31 in the adjustment direction V1 and directly the lever 309 'and thus the door 2 driven until a maximum open position (see FIG. 12C ) is reached, which may correspond to a pivot angle of the door leaf 2 greater than 90 °, for example 120 °. The closing is exactly the reverse by moving the push rod 31 against the first adjustment V1.

When opening the door leaf 2 in the second opening direction 02, the coupling element 307 is implemented relative to the lever 309 ', as can be seen from a comparative overview of FIGS. 12A and 13A. To open the door leaf 2 in the opening direction 02, the push rod 31 is moved in the second adjustment direction V2 and thereby the coupling element 307 is rotated in the second rotational direction D2, so that according to the lever 309 'and thus the door 2 are pivoted. In the embodiment according to FIGS. 7 to 13A-13C, the coupling element 307 is positively coupled to the lever 309 '. There is thus no slipping clutch provided. Accordingly, the drive device is advantageously not designed to be self-locking, so that a manual closing of the door leaf from an open position is possible.

Of course, but also in this embodiment, the provision of a slip clutch according to the type described above is conceivable and possible. In addition, an electronic control unit 4 for controlling the drive device 2 is shown in FIGS. 7 to 13A-13C. In this case, the control electronics 4 are arranged on the transverse section 102 of the frame 10, it being possible for the control electronics 4 to be arranged in different positions on the transverse section 2, depending on the structural possibilities (compare the different, exemplary arrangements, for example, in FIG. 10 and FIG. 12A).

FIGS. 14A and 14B show a concrete embodiment of a drive device 3 with a spindle drive. The drive device 3 has a spindle 32 which extends along a longitudinal axis L, is rotatably mounted on a housing 30 and is in communication with a gear 34 and an electric motor 35.

The spindle 32 has on its externa ßeren lateral surface on Au ßengewinde, which is in engagement with an internal thread on a bore 313 of a spindle nut 310. The spindle nut 310 is rotatably held on an (inner) tube of a push rod 31, which is mounted in a cladding tube 312 via an end face 314 facing away from the spindle nut 310. The cladding tube 312 is displaceably (but non-rotatably) mounted on the housing 30 along the longitudinal axis L, so that the tube 31 1 is guided on the housing 30 via the cladding tube 312. At the end face 314 of the push rod 31, there is disposed a coupling point 301 for coupling the push rod 31 to the hinge rod 303 (see, for example, Fig. 2).

During operation of the drive device 3, the electric motor 35 via the gear 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 on the push rod 31, the spindle nut 310 rolls the spindle 32, so that the spindle nut 310 along the longitudinal axis L relative to the spindle 32 is adjusted and together with the spindle nut 310, the tube 31 1 and the cladding tube 312 are moved and thus the entire push rod 31 is moved.

14A shows the drive device 3 in an extended position, in which the spindle nut 310 is moved to an end of the spindle 32 facing away from the gear 34. On the other hand, FIG. 14B shows the drive device 3 in a retracted position, in which the spindle nut 310 approximates the end of the spindle 32 facing the gearbox 34. The push rod 31 is biased by a spring 33 in the form of a compression spring relative to the housing 30 and supported on a support 36 on the housing 30. The bias is in this case - in the illustrated example - in the direction of the extended position (see Fig. 14A), so that the spring 33 is tensioned against the adjustment direction V upon retraction of the push rod 31, as shown in Fig. 14B ,

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

It is also possible to compensate by means of the spring 33 acting on a swing wing weight forces. This can be particularly advantageous if (as with a tilting window) weight forces acting on the pivoting wing also act on the drive device 3. These weight forces can be compensated by a suitable bias, so that it can not come to an automatic adjustment of the swing wing due to weight forces. Of course - depending on use and technical requirement - the spring 33 also cause a reverse bias and thus bias the push rod 31 in the direction of its extended position.

Optionally, the spring 33 may also be dispensed with, in particular if a bias in a specific starting position is not desired (as in the embodiment according to FIGS. 7 to 13A-13C) or if no (significant) weight forces act on a pivoting wing, by a spring have to be compensated (as is the case for example with a vertically directed pivot axis of the swing leaf, for example in a door of the type shown in Fig. 1). A modified embodiment of a drive device 3 in which no spring is provided for biasing a push rod 31 relative to a housing 30, Fig. 15. In the modified embodiment, as in the embodiment of FIGS. 14A and 14B, a spindle 32 is rotatably mounted and is engaged with a gear 34 and an electric motor 35. In operation, the drive device 3, the spindle 32 is set in a rotational movement such that a standing with an external thread of the spindle 32, a bore 313 having spindle nut 310 rolls on the spindle 32 and along an adjustment V axially relative to the spindle 32 is moved , A pipe 31 1 is coupled to the spindle nut 310, on whose end face 314 a coupling point 301 for connection to a joint rod 303 (see, for example, FIG. 2) is arranged.

The tube 31 1 of the push rod 31 is axially displaceably mounted on the housing 30, but not biased by a spring relative to the housing 30. 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 described with reference to FIGS. 14A and 14B, so that reference should be made to the preceding embodiments.

16 to 20 show a further embodiment of a drive device 3, which is arranged on a transverse section 102 of a frame 10 and serves for adjusting a pivoting wing relative to the frame 10.

The drive device 3 has, as shown in Fig. 17 and 18, a spindle 32 which is connected via a gear 34 with an electric motor 35 and is set in operation via the electric motor 35 and the gear 34 in a rotary motion. With the spindle 32 is a spindle nut 310 in threaded engagement, so that by a rotational movement of the spindle 32, the spindle nut 310 rolls on the spindle 32 and is moved longitudinally along the spindle 32. The drive device 3 has a housing 30, which encloses the essential components, in particular the spindle nut 310, the spindle 32, the gear 34 and the electric motor 35, the drive device 3. The drive device 3 is arranged on a fastening element 1 1 and held on the fastening element 1 1 at the transverse portion 102 of the frame 10. The fastening element 1 1 has for this purpose holding portions 1 10, 1 1 1, between which the drive device 3 is held. At the holding portion 1 10 (in Fig. 16 left) in this case a bearing element 1 12 is arranged, via which the spindle 32 is rotatably mounted and which serves as an axial termination of the housing 30.

For fixing the drive device 3 to the fastening element 1 1, a mounting bracket 39 is provided, which is attached via abutment sections 391, 392 on the fastening element 1 1 and with a Umgriffsabschnitt 393, the housing 30 surrounds. The mounting bracket 39 is located between a front stop portion 1 15 on the holding portion 1 10 of the fastener 1 1 and a rear stop portion 1 14. The stopper sections 1 14, 1 15 serve as an axial boundary of the movement path of the spindle nut 310 within the housing 30, so that the Spindle nut 310 between the stop portions 1 14, 1 15 is axially adjustable.

As can be seen from Figures 17, 18 and 19, the spindle nut 310 is above a pin

316 in engagement with a slot 303 B of a hinge rod 303 which is fixedly connected to a coupling element 307. As shown in Fig. 19, the coupling element 307 is in this case coupled via a pin 308 with a lever 309, so that by rotating the coupling member 307 of the lever 309 is pivoted and about an adjusting force in the swing-wing (see, for example, Fig. 1) can be initiated , as has already been described above.

On the pin 316, a guide portion 317 is arranged, via which the pin 316 positively in a guide track 1 13, which is formed in the fastener 1 1, out. Via the pin 316 and the guide section arranged thereon

317, the spindle nut 310 thus rotatably guided on the fastening element 1 1, so that upon rotation of the spindle 32, the spindle nut 310 can not rotate and is moved along along the spindle 32.

By the engagement of the pin 316 in the slot 303 B of the pivot rod 303, the longitudinal movement of the spindle nut 310 is converted during operation of the drive device 3 In this case, a change in distance between the coupling element 307 and the spindle nut 310 is compensated by the slot 303B, so that the spindle nut 310 along a longitudinal displacement along the spindle 32 can take the joint rod 303 ,

Along the spindle 32 extends between the spindle nut 310 and the gear 34, a spring 33 in the form of a compression spring which is tensioned at an approximation of the spindle nut 310 to the gear 34, ie in the direction of the transmission side stop portion 1 14, to pressure. The spring 33 is supported on the spindle nut 310 via a bushing 315 which positively engages via a collar 315A in a recess 31 OA of the spindle nut 310, wherein the bush 315 has a further collar 315B, which faces the spring 33 and to the the spring 33 is attached. The spindle nut 310 may be made of plastic, for example. By contrast, the bushing 315 can, for example, be made as a metal bush, so that a firm support of the spring 33 on the spindle nut 310 is provided via the bushing 315. During operation of the drive device 3, an adjusting force is introduced via the spindle nut 310 and the pin 316 into the articulated rod 303. In order to reinforce the made of plastic spindle nut 310 in the region of the pin 316, a reinforcing element 318 is provided in the form of a bolt, which is arranged in the interior of the otherwise made of plastic pin 316 and, for example, made of metal, for. As steel.

As can be seen from the sectional views of FIGS. 18 and 19, the spindle nut 310 has an internal thread 31 OB, via which the spindle nut 310 is in threaded engagement with the spindle 32.

Fig. 20 shows a cross-sectional view of the spindle nut 310 in the housing 30. The housing 30 has a slot-like opening 30A, through which the pin 316 of the spindle nut 310 engages and along which the pin 316 can be adjusted during an adjustment movement of the spindle 310. The housing 30 is encompassed by the mounting bracket 39, so that the housing 30 and thus the drive device 3 via the mounting bracket 39 fixed to the fastener 1 1 and above it to the transverse portion 102 of the frame 10 is held. As can be seen from FIG. 20, the spindle nut 310 is at least partially in contact with an inner side of the housing 30, so that the housing 30 guides the spindle nut 310 at least approximately free of play.

As shown in FIG. 16, a bearing point 390, in which the coupling element 307 is arranged and via which the coupling element 307 is mounted on the fastening angle 39 and thus on the drive device 3, is formed on the fastening angle 39. In this case, the coupling element 307 extends through the fastening element 11, as can be seen in FIG. 19, and is connected at its end remote from the drive device 3 to the lever 309 and above to the pivoting wing. By pivoting the coupling element 307, the pivoting wing can thus be moved to open or close. By the spring 33 in this case a bias voltage is provided which can cause an automatic return movement, for example, after opening the pivoting vane, especially in non-self-locking design of the spindle drive. By movement of the spindle nut 310 in the direction of the transmission-side stop portion 1 14, for example, to open the pivoting vane, the spring 33 is tensioned, so that after opening due to the biasing forces an automatic backward movement of the spindle nut 310 and thus a return dividing the pivoting wing is effected in a starting position.

The idea underlying the invention is not limited to the above-described embodiments, but can also be realized in completely different types of embodiments.

For example, the locking device is not necessarily to be realized as a building door, but may also be designed as a building window or as other closing devices for a building opening.

Although the drive device is advantageously arranged at the transverse portion of the frame, because there is sufficient space for receiving the drive device available here. This is not to be understood as limiting. The drive device can also be arranged in other locations and in other positions on the frame or the pivoting wing. If the drive device is arranged on the pivoting wing, the coupling element is correspondingly arranged rotatably on the pivoting wing and coupled with corresponding counterparts on the transverse section of the frame.
