That in principle in Fig. 1 shown panning o. The like. Is shown here in the preferred application as a garage pivot with a one-piece door leaf. As already explained in the general part of the description, the teaching of the invention is equally applicable to a sectional door.

In Fig. 1 A door frame 1 can be seen at a door opening 2 of a garage.

Opposite the door frame 1, a door leaf 3 is movable between a closed position and an open position. Fig. 1 shows the closed position. Visible are the usual wheels, rails and motion support springs, which are not provided with reference numerals.

The pivoting mechanism has a locking device 4 arranged on the door leaf 3 with a locking housing 5, by means of which the door leaf 3 can be locked in the closed position with the door frame 1 or a stationary component. The locking device 4 has a manually adjustable actuator 6 for locking and unlocking and a manually adjustable actuation lock 7. The operation of such an actuator 6 and such an actuation lock 7 has been explained in the introductory part of the description.

The representation in the Fig. 3 to 5 shows the structure of the actuator 8 according to the invention, which serves the motorized adjustment of the actuator 6 on the one hand and the actuating lock 7 on the other. The actuating drive 8 is here equipped with a drive housing 9 and therein with an electric drive motor 10 with a downstream gear assembly 11.

The retrofitting of the actuator 8 for in the Fig. 1 and 2 shown pivot is possible in a particularly simple manner. For retrofitting the actuating drive 8, the drive housing 9 is namely attachable to the lock housing 5. The full meaning of the term "attachable" has been explained in the general part of the description. Here the Aufstekken takes place in a direction perpendicular to the door panel. 3

Fig. 2 shows the locking device 4 before attaching the actuating drive eighth Fig. 3 shows the arrangement with retrofitted, so plugged or mounted actuator 8.

It is essential that when attaching the drive housing 9 on the locking housing 5, the gear assembly 11 comes into engagement with the actuator 6 on the one hand and the operating lock 7 on the other. As a result, the actuator 6 on the one hand and the operating lock 7 on the other hand can be adjusted by means of the drive motor 10 in the mounted state.

For a fixation of the actuating drive 8 on the pivot, in particular on the locking device 4, here an elongated lock screw 12 is used, which is provided only for fixing the locking device 4. In principle, however, the actuation drive 8 can also be fastened to the pivot or to the locking device 4 by means of a snap fixation or the like.

It is a synopsis of Fig. 1 and 2 it can be seen that the actuator 6 has an actuating shaft 6a and an operating handle 6b which can be plugged onto the actuating shaft 6a. A synopsis of Fig. 2 and 3 also shows that the operating handle 6b for retrofitting the actuating drive 8 is first disassembled.

The actuating shaft 6a is preferably equipped with a square profile. Here are also other types of profiles possible.

The actuating lock 7 has in the illustrated and so far preferred Ausfühnmgsbeispiel a locking lever 13 which is designed to be displaceable. Here are also pivotable or rotatable locking lever conceivable.

The locking device 4 can be configured in different variants. In the illustrated and so far preferred embodiment, it is provided that the actuator 6 from a in Fig. 1 shown normal position out in the locking direction, in Fig. 1 rechtsherum, is adjustable, whereby the locking device 4 can be brought into the locked state. After locking the actuator 6 falls back into the in Fig. 1 shown normal position. In an adjustment of the actuator 6 from the normal position in the unlocking, in Fig. 1 To the left, the locking device can be 4 in the unlocked state. Subsequently, the actuator 6 falls back into the normal position.

Another variant of the realization of the locking device 4 is that the actuator 6 is adjustable in the locking direction from an unlocked position into a locking position and in the unlocking from the locking position out into the unlocked position. This variant is not shown.

In all relevant variants of the locking device 4, it is such that the locking lever 13 and thus the operating lock 7 in a blocking position ( Fig. 2 ) is brought and preferably biased in this blocking position. In the blocking position, the operating lock 7 locks an adjustment of the actuator 6 in the unlocking direction. Before each unlocking, be it motorized or manual, so the operating lock 7 is initially on the locking lever 13 to solve.

The representation in Fig. 5 is the constructive structure of the actuator 8 can be seen.

The gear assembly 11 has a first coupling element 14 for engagement with the actuator 6, preferably with the actuating shaft 6a, and a second coupling element 15 for engagement with the actuating lock 7, preferably with the locking lever 13 on. Both coupling elements 14, 15 can be driven by means of the drive motor 10. About the coupling elements 14, 15 so to speak, the driving force of the drive motor 10 is transmitted to the actuator 6 on the one hand and on the operating lock 7 on the other.

The first coupling element 14 is configured pivotable here and has a profile for the positive engagement with the actuator 6, here with the actuating shaft 6a on. In this case, the first coupling element 14 is preferably aligned coaxially with the actuating shaft 6a. In the present case, the engagement between the actuating shaft 6a and the first coupling element 14 is a positive engagement via the above-mentioned square profile.

The second coupling element 15 is preferably designed as a lever pivotable about a lever axis 16, which at one end a recess 17 o. The like. has, with which the actuation lock 7, in this case the locking lever 13 of the actuation lock 7, is engaged.

The mounting side, so the back of the actuator 8, shows Fig. 4 , Here it can be seen that the first coupling element 14 and the second coupling element 15 are accessible through corresponding recesses in the drive housing 9 through and form the necessary connections for the actuator 6 and the actuation lock 7.

The central element for driving the coupling elements 14, 15 is preferably a driving element 19 which is in engagement with the drive motor 10 or with an intermediate gear 18 connected to the drive motor 10. As will be explained below, the drive element 19 is driven by the drive motor 10 , selectively with the first coupling element 14 and the second coupling element 15 in engagement, which in turn the two coupling elements 14, 15 are driven.

With the first coupling element 14, the drive element 19 is coupled via a freewheel 20, so that a manual adjustment of the actuator 6 without an adjustment of the drive element 19 is possible. In the present case, such a freewheel 20 can be realized particularly simply, since the drive element 19 is designed to be pivotable and aligned coaxially with the first coupling element 14. The freewheel 20 is nothing more than a recess in the first coupling element 14th

The drive element 19 has a driver 21, which comes after passing through the freewheel 20 with stop edges 22 in engagement. The angular range over which the recess extends is decisive here for the size of the freewheel 20.

The drive element 19 is mounted on the first coupling element 14. In principle, however, the drive element 19 can also be mounted on the drive housing 9.

With the second coupling element 15, the drive element 19 is preferably coupled via a cam arrangement. In the illustrated and so far preferred Embodiment, the cam assembly is provided by the driver 21, which extends in the axial direction through the drive member 19 therethrough, and on the back of the drive member 19 in engagement with the second coupling element 15 can be brought.

The actuating drive 8 preferably operates so that when driving the drive element 19 in a first drive direction, in Fig. 5 To the left, initially the cam arrangement, ie the driver 21, an adjustment of the second coupling element 15, in Fig. 5 to the right and thus releasing the operating lock 7 causes, meanwhile, the freewheel 20 between the drive element 19 and the first coupling element 14 is traversed and then causes the further adjustment of the drive element 19, an adjustment of the first coupling element 14 and thus an adjustment of the actuator 6 in the unlocking ,

The actuation drive 8 thus first solves the actuation lock 7 and then adjusts the actuation 6 in the unlocking direction.

When driving the drive element 19 in a second, the first drive direction opposite drive direction, in Fig. 5 right around, the drive element 19 comes after passing through the freewheel 20 into engagement with the first coupling element 14, whereby the actuator 6 is adjusted in the locking direction.

From the above explanation of the operation it is clear that the actuator 6 is manually adjustable from the normal position out with not energized drive motor 10 in both directions. This is only possible because it is here at the freewheel 20 is a two-way freewheel. In the above-mentioned, second variant of the locking device 4, such a two-way freewheel is not required.

In the arrangement described above with two-way freewheel 20, the drive element 19 is always in the after motorized locking and unlocking Fig. 5 reset initial position shown.

A particularly high compactness can be achieved by using the walls of the drive housing 9 for mounting, for example, the first coupling element 14 and / or the second coupling element 15. Here, for example, it is such that the first coupling element 14 is mounted on the door leaf 3 facing the drive housing 9. Furthermore, the lever axis 16 is likewise mounted on the door leaf 3 facing the drive housing 9.

It can be the representation in Fig. 3 It can be seen that the drive housing 9 has an opening 23 aligned with the first coupling element 14 and that the actuation grip 6b can be pushed onto the actuation shaft 6a through the opening 23. In principle, however, the actuating handle 6b can also be plugged onto the first coupling element 14. Overall, this can be done in an elegant way next to the motor and manual operation.

The manual release of the operating lock 7 can preferably be realized in that the second coupling element 15 protrudes from the drive housing 9 and that by means of protruding from the drive housing 9 portion 15b of the second coupling element 15, the actuation lock 7 is manually releasable.

The actuating drive 8 described above can in principle also be used for manually adjustable swing gates or the like. But is particularly advantageous use in an arrangement with an electric door drive 24 for the motorized adjustment of the pivoting gate. The door drive 24 is preferably equipped with an electrical control device. The control device is coupled in such a control technology with the drive motor 10 of the actuating drive 8, that the control device initially causes the motorized adjustment of the door leaf 3 by means of the door drive 24 and then the motorized locking of the locking device 4 by means of the actuating drive 8 during motorized closing of the swing gate.

There are numerous ways to fix the door leaf 3 for the lock. Preferably, the locking device 4 is equipped with two lateral bars 25 and / or a lower latch and / or an upper latch such that the latch 25 are respectively extended in befindlichem in the locked state locking device 4 and with a corresponding, not shown strike plate on the door frame 1 or a stationary component engage. When in the unlocked state locking device 4, the latch 25 are each retracted and therefore are out of engagement of the corresponding closing surfaces. The coupling of the bolt 25 is preferably carried out via rods 25 a, Bowden cables, cables o. The like ..

An anti-burglary arrangement results from the fact that the locking device 4 located in the locked state holds the latch 25 or the latch 25 in each case in the extended state. In this case, a Rückdrükken the latch 25 is not possible. But this also means that snapping the latch 25 when closing the swing gate is not possible. Thus, the latches 25 must be retracted and extended in a predetermined manner in order to avoid blocking or jamming when opening or closing the pivoting gate. This can be realized in a particularly simple manner via the actuating drive 8 described above with suitable control.

The motor unlocking and locking and / or the motorized adjustment of the pivoting gate can be triggered by an electrical switching element, by a remote control o. The use of proximity switches is conceivable. Arrangements can advantageously be used for the power supply, which can be charged by means of solar cells.

According to another teaching, the self-importance, the claimed equipped with the actuator 8 pivot is claimed. Reference may be made to the above statements.
