Description

The invention relates to a driver device for a door drive device. Moreover, the invention relates to such a door drive device and a gate.

There are various types of door drive devices, which are adapted to the respective driven gates and the local conditions. For universal use in overhead doors such as sectional doors and / or swing or tilt gates in particular door drive devices are widespread, which have along a guide means, ie usually a guide rail, reciprocally guided driving carriage. The guide device is usually arranged on the ceiling of the door to be closed by the door in the direction of movement of the overhead door. The door drive devices have a motor drive unit, which is usually formed by a drive head with a geared motor, wherein the accommodated in the drive head motor gear is usually formed self-locking. Further, the guide means is associated with a further transmission which transmits a tapped at an output shaft of the motor drive unit rotational movement in a linear movement. As traction means usually a toothed belt is used, which forms an endless loop. About a coupling part of the guided on the guide rail driving carriage can be connected. Furthermore, the door leaf is connected via a coupling linkage to the driving carriage.

In this way, the door leaf is taken and opened or closed in a reciprocating motion of the driver carriage.

Due to the self-locking of the motor gearbox, the door leaf is blocked by the guide rail associated gear when the motor drive unit, so that the door can not be opened without authorization from the outside.

In accidents, such as power outages or other malfunctions of the motor drive unit, the door leaf remains blocked, so that even an authorized user can not open the gate.

For this case is in the DE 20 2005 009 012 U1 an emergency unlocking device is provided, with which the driving carriage can be uncoupled from the drive unit. In this way, the carrier slide and thus also the door leaf after an emergency release independently of the affected by the accident gear along the guide device is freely displaced. To secure the emergency release on the drive carriage in normal operation and to prevent a crash of the door leaf in an emergency release, a releasable under destruction or under tool or key insert safety device is provided.

Thus, the alternative solution with destruction of the safety device has the disadvantage that at least the safety device and possibly also the emergency unlocking be repaired after occurred accident and emergency release or replaced by appropriate new components or even the complete door drive must be replaced. In the other alternative solution with a release of the securing device by means of tools, just such a tool must be provided and requires a complex handling.

The invention has for its object to improve a driving device for a door drive device of the type mentioned in such a way that an emergency release after a major accident in a simple manner and the emergency release is repeatedly feasible.

This object is achieved by a driver device with the features of claim 1.

A provided with such a driver door drive device and a gate with a door leaf and such a door drive device are each the subject of a secondary claim.

Advantageous embodiments of the invention are the subject of the dependent claims.

One idea of the invention is accordingly to provide a switchable coupling device which can be switched from a locking position into an unlocking position and vice versa such that in the unlocked position the first driver device and the second driver device are decoupled and in the locking position the first driver device is coupled to the second driver device is and wherein a means for holding the coupling device in the unlocked position and for holding the coupling device is provided in the locking position.

In this way, the entrainment devices in normal operation, ie not in accidents, connected to each other and together along the guide device movable. This is ensured by the coupling device, which can also be understood as an emergency unlocking device, characterized in that in the normal operation associated latching position, the first cam means coupled to the second cam means and in the unlocked position, ie, for example, in a fault, the first and second entrainment means are decoupled.

Another idea of the invention is that after an emergency release, i. H. a transfer of the coupling device from the locking position to the unlocked position, in a simple way the reverse process with a restoration of the initial state by a return transfer of the coupling device from the unlocked position into the locking position is possible. For this purpose, the coupling device is designed in a suitable manner.

In this way, the entrainment device, in particular the coupling device, can be used for an unlimited number of emergency releases without their components having to be destroyed or set in a complicated manner by means of a tool insert.

In a preferred embodiment, the first entrainment device is formed by a traction means or a Zugmittelkupplung and the second entrainment means by a carriage body. Thus, the emergency release can be done at the junction of traction means and carriage body.

Alternatively, to enable an emergency release in the region of the slide body guided along the guide device, the first entrainment device can be formed by a first carriage body unit and the second entrainment device can be formed by a second carriage body unit. In other words, the carriage body can be subdivided into two or more carriage body units, which can then be moved independently of one another along the guide device in the decoupled state (unlocking position). Thereby, a unit formed of door leaf and associated carriage body unit separately from another unit formed by drive unit, traction means and other carriage body unit are moved along the guide rail.

In a further preferred embodiment, the coupling device is translationally movable from the locking position into the unlocked position and vice versa. Alternatively, this position change could also be accomplished by a rotational movement of the clutch device or a component thereof. Preferably, the translational movement takes place in a direction transversely, in particular perpendicular, to the longitudinal direction of the guide device.

Preferably, the coupling device comprises at least one movable coupling element, in particular a coupling slide or pin, wherein the coupling element for coupling of first and second driving means engage in a recess and can be removed from the recess for decoupling of first and second driving means. The recess may advantageously be provided in the second entrainment device.

It is further preferred if the coupling element is guided translationally movable along a channel. Advantageously, a bore is provided for this purpose in the first driver, along which the coupling element is reciprocally guided. Preferably, this bore is provided in a region of the first driver device, so that the coupling element can extend out of the guide device in the unlocked position. In this way, the coupling element is accessible by an authorized user by means of an actuating element in case of failure.

Furthermore, at least one biasing device may be provided, which forms the means for holding and / or the coupling element from the locking position moved to the unlocked position and vice versa. In other words, can be provided for the holding means and for the adjustment of the coupling element advantageously a common biasing means. In principle, however, it is also possible in each case to provide a pretensioning device for this purpose.

In a further preferred embodiment, the biasing device comprises a bistable body, in particular a bistable spring unit. The bistable body can take two stable positions, states or positions. This is preferably a locking position and an unlocking position. This bistable body can change from one to the other state through an external impulse. This can be done, for example, by actuating the actuating unit, preferably in the form of a drawstring or rod.

It is further preferred if the biasing means is switchable such that the coupling device is biased in the locking position and / or in the unlocked position. Thus, the coupling device can be kept biased in only one desired position or in several desired positions.

In a particularly preferred embodiment, the biasing device comprises at least one spring unit, preferably at least one leaf spring. Furthermore, the coupling device and / or the biasing means may be formed of plastic. In order to enable a simple production, it is provided in a preferred embodiment that the coupling device and the biasing device are formed as a component. In this way, a cost-effective production is possible. Particularly preferred are two leaf springs are provided, which are molded onto the coupling element. Such a coupling and biasing device is very durable and can easily by pulling or pressing the coupling element are each folded over a predetermined dead point, so that the respective desired position, ie the locking position or the unlocking position, is adjustable.

In a further preferred embodiment, at least one stop is provided, which determines the locking position and / or the unlocked position. This proves to be advantageous in particular in the design of the spring unit as a leaf spring. Thus, after pulling or pressing beyond the respective dead point, the leaf spring can be folded down and limited by the stop.

Advantageously, the stop can be formed by a nose and a hook, wherein the nose is in communication with the coupling device, in particular with the coupling element, and the hook with the first entrainment device. Thus, the nose can prevent movement of the coupling element in the direction beyond the locking position addition. This prevents the coupling device, in particular the coupling element, from protruding too far upwards and thus blocking a movement of the first entrainment device in the direction of the second entrainment device. In other words, the nose limits the movement of the coupling element in the direction of the second driving device. Furthermore, the design of nose and hook allows easy mounting of the coupling device, in particular of the coupling element, on the first entrainment device. Thus, the coupling slide can be inserted into the channel of the first driving device, so that the nose can be pushed past first on the preferably partially flexible hook down and then the nose can engage a projection of the jump back to its original position hook. The hook is preferably designed as a snap hook and the nose preferably as a latching lug.

Furthermore, the stop may have at least one stop surface which determines the locking position and / or the unlocking position. Thus, the stop surface may be provided for example in a lower region of the first driving means, so that the stop surface limits the folding movement of the leaf spring downwards.

In order to achieve a simple fixing, the pretensioning device, in particular the leaf spring, engages in at least one groove of the first entrainment device. In preferred use of two leaf springs, two grooves are accordingly preferably provided. In the case of a single groove, this may for example also be designed as a circumferential annular groove.

For easy shaping of the driving device, the at least one groove is provided adjacent to the stop surface or as part of the stop surface. Thus, the stop surface, for example, pass directly into the groove or connect to it. Basically, it is sufficient that the groove and / or the associated connection region of the stop surface are shaped and formed such that the leaf spring is movable at least insofar as a folding of the leaf spring to achieve the locking or unlocking position is possible.

In a preferred embodiment, the coupling device can be transferred by means of an actuating unit, preferably by means of a pull cord or pull rod, from the locking position to the unlocked position and vice versa. The actuating unit is preferably operated manually. Thus, for example, for an authorized person located in the interior of a garage, it is possible in a simple manner to carry out an emergency unlocking of the carrier carriage running in the area of the ceiling of the garage by means of a drawstring or rod.

In order to bring the coupling device and thus also the carriage body back into the original state for normal operation even after such an emergency unlocking, it can be provided in a preferred embodiment that the second driving device has at least one positioning means, by which the coupling element from the locking position in one direction is movable towards the unlocked position.

In this regard, it is preferred if the positioning means is formed by at least one stop step which is oriented in such a way that the coupling element can come into contact with the stop ramp during movement of at least one entrainment device along the guide means and thereby at least be movable in the direction of the unlocking position, that the coupling element can be transferred into the locking position. It is preferably provided that the coupling element can be brought into the recess of the second driving device in engagement.

In a particularly preferred embodiment, the switchable coupling device comprises two slide body units, which are linearly movable along the guide device, as driver devices, which are guided in parallel in the guide rail. A coupling element in the form of a coupling slide with two molded leaf springs allows the adjustment of the coupling device in the locking position and the unlocking position and vice versa. For this purpose, the first carriage body unit includes a groove or bore in which the coupling slide is movably guided in a direction directed substantially perpendicular to the longitudinal extent of the guide device. Furthermore, the first carriage body unit bearing points, in particular in the form of a groove to support the leaf springs rotatably with their free ends. The second carriage body unit comprises a recess in which the coupling slide can engage in the locking position.

This switchable coupling device serves to keep the two carriage body units in the locking position during normal operation, so that a linear drive movement of the second carriage body unit along the guide device is transmitted to the first carriage body unit. This engaged state can be securely held by the clutch device. Should an emergency occur, for example, a transmission damage or a power failure, which has the consequence that no more drive takes place, can be disengaged by a single unit, for example in the form of a rope, by a simple, single operation by pulling on the rope of the coupling slide such that the first carriage body unit is movable relative to the second carriage body unit. Furthermore, the decoupled state can also be kept safe, in particular as a result of the leaf springs.

Subsequently, the door leaf can be moved, for example, under manual application of force in the opening or closing direction. In order to achieve a restoration of normal operation at a later time, the first carriage body unit or the coupling device 'can be coupled by a simple operation, for example with a rod, rope or by manually pushing up the coupling slide again.

For this purpose, the transfer of the coupling slide into the locking position preferably takes place in a situation in which the two carriage body units are positioned spaced from each other along the guide means. After pushing up the coupling slide, the first carriage body unit can then be moved in the direction of the second carriage body unit. In order to prevent too high a position of the coupling slide, a stop is provided, which may be formed by a latching nose and a snap hook, wherein the latching lug on the coupling slide and the snap hook on the first driving device is appropriate. The snap hook prevents the detent from moving the coupling slider beyond a maximum upper position, in particular from moving in the direction beyond the locking position. This prevents the coupling device, in particular the coupling slide, from protruding too far upwards, thus blocking the return of the first entrainment device into the coupled position of the first entrainment device and the second entrainment device. This means that the upper end of the coupling slide must not be allowed to protrude beyond the upper end of the second driving device, in particular not be higher than the uppermost point of a stop ramp on the second carriage body unit. By this Anschlagrampe namely the coupling slide is pressed against the bias caused by the leaf spring bias down when it hits the Anschlagrampe until the two Schlittenkörpereinheiten are approximately at the same height of the guide means and the coupling slide in the position after the Anschlagrampe recess after can snap in at the top. Thus, the initial state for normal operation is again reached with engaged clutch device and is held securely.

In order to achieve in each case a bias of the coupling slide in the locking position but also in the unlocked position, the spring unit is formed in a preferred embodiment by at least one leaf spring, preferably by two leaf springs.

The at least one leaf spring is considered in longitudinal section through the carriage body longer than the distance between the bearing points for the leaf spring (excess length). When mounting the coupling slider in the first carriage body unit, the leaf spring is elastically bent. After locking in the bearings, the leaf spring remains bent due to their excess length. In this way, the connection point between leaf spring and coupling slide is located in the locking position above and in the unlocked position below an imaginary line connecting the bearings. These positions correspond to the states "engaged" and "disengaged". The leaf spring overlength is adjusted to the distance between the bearings or the distance between the bearing point and connection point on the coupling slide so that the coupling slide is pushed a bit out of his leadership or bore and engages in the recess of the second carriage body unit. As a result, the positive connection with the second carriage body unit is produced.

In the above-mentioned operation of the actuator unit, the coupling slide is pulled against the leaf spring deflection over a dead center until the leaf spring folds down. Also by actuation of the actuator unit, the coupling slide can be pushed back against the leaf spring deflection beyond the dead center until the leaf spring folds upwards. Due to the leaf spring deflection responsible for this bias, the "engaged" and "disengaged" positions are each securely held.

The Fig. 1 shows a door 140 with a door leaf 100 and a door leaf moving door drive device 110. The door drive device 110 includes a guide device 120 with a cross-sectionally approximately C-shaped Guide rail 122 and a motor drive unit 124. Furthermore, is off Fig. 1 a coupling link 102 can be seen, via which the door leaf 100 is connected to the door drive device 110 for moving the door leaf 100. The coupling linkage 102 is connected at one end to the door leaf 100 and at the other end to a connection 90 of a driver device 10. The connection of the terminal 90 to the driving carriage 10 can be the FIGS. 2 to 8 , in particular the perspective bottom views according to FIGS. 2 and 3 and the associated, along the central axis of the guide rail 102 cut perspective views according to the FIGS. 4 and 5 , remove. Furthermore, the show FIGS. 6 and 7 a longitudinal and a cross section through the driver device 10th

Like that FIGS. 2 to 8 , especially the FIGS. 6 to 8 , the entrainment device 10 comprises a carriage body 20 having a first entrainment device 30 and a second entrainment device 40. The carriage body 20 is designed to be linearly guided along the guide device 120, wherein the entrainment devices 30, 40 are respectively guided on the guide rail 122.

For coupling or decoupling of the two entrainment devices 30, 40 or for uncoupling the entrainment device 10 from the drive unit 124, a coupling device 60 is provided. Such uncoupling of the driver 10 of the drive unit 124 is intended in particular in case of failure, for example in a transmission damage or a power failure, an opening or closing of the door leaf 100 by manual manual operation, preferably via a handle 104 allow. This is particularly necessary when the door drive is self-locking and thus in an accident, the driver 10 is firmly seated in its corresponding position along the guide device 120 and can not be solved.

The coupling device 60 comprises a coupling element 62, which is adjustable from an interlocking position, in which the two driver devices 30, 40 can be moved together by the door drive 110 along the guide device 120, into an unlocking position. In this unlocking position (see Fig. 8 ), the first carrier device 30 is movable independently of the second driver device 40 along the guide device 120.

In the embodiment shown, the coupling element 62 is formed by a pin or slider and guided in a substantially vertically aligned channel 38 and bore in the first cam means 30. In this way, in the unlocked position, the first driving device 30 and the second driving device 40 are decoupled, whereas in the locking position, the first driving device 30 is coupled to the second driving device 40. In other words, the coupling element 62 is movably guided in the first driver device 30 along the channel 38. In order to achieve a locking of the coupling device 60 in normal operation, ie such a connection of the two carrier devices 30, 40, that the entire carrier slide 10 is movable along the guide device 120, a recess 42 is provided in the second driver 40, which is substantially the same Cross-section as the channel 38, so that the coupling element 62 can engage in the recess 42 in the locking position. This coupled state of the locking position is in Fig. 6 in a longitudinal section and in Fig. 7 shown in a cross section.

Furthermore, the entrainment device 10 comprises a biasing device 70, which is formed by a spring unit with two leaf springs 72, 74 made of plastic. The leaf springs 72, 74 are molded onto the coupling element 62, so that the coupling element 62 and the biasing device 70 are formed as a component.

For the storage of the two leaf springs 72, 74, the first driving device 30 has two grooves 36, 37, in each of which a first free end 76 of the leaf spring 72, 74 is mounted rotatably. A second end 78 of the respective leaf spring 72, 74 connects rigidly to the coupling element 62. Here, in each case the length between the two ends 76, 78 chosen so that the respective leaf spring 72, 74 undergoes a bend and thus a bias. In other words, the leaf springs 72, 74 in the longitudinal section according to Fig. 6 considered longer than the direct distance between the ends 76, 78. In addition, the position of the grooves 36, 37 and the connection connections of the leaf springs 72, 74 to the coupling element 62 in the region of the second ends 78 are coordinated such that an upper dead center and a bottom dead center, and at a bend of the leaf spring 72, 74 beyond the dead center, a folding of the leaf spring 72, 74 and thus a displacement of the coupling element 62 up or down, ie in the locked position or the unlocked position.

Furthermore, the driving device 10 comprises two stops 31 and 34, wherein the stop 31 determines the locking position of the coupling device 60 and the stop 34, the unlocked position of the coupling device 60 and in particular each of the coupling element 62.

As Fig. 7 shows the stopper 31 is formed by a nose 32 in the form of a latching nose and a hook 33 in the form of a snap hook. The nose 32 is attached to the coupling member 62 and the hook 33 is attached to the first cam means 30. This embodiment initially allows easy mounting of the coupling element 62. For this purpose, the coupling element 62 is inserted from above into the channel 38. As soon as the nose 32 strikes the at least partially flexible hook 33, this becomes so far pushed outward until the nose 32 can be pressed past the hook 33 further down. After the nose 32 has passed the hook 33, the hook snaps 33 back to its original position (see Fig. 7 ). Now, the coupling element 62 is in the mounted position and is slidably mounted in the channel 38 along the longitudinal direction. Furthermore, this configuration of nose 32 and hook 33 allows a position of the coupling element 62 can be prevented, which is too far above relative to the second driving device 40. Namely, the hook 33 prevents the nose 32 from moving in such a way that the coupling element 62 protrudes too far upwards from the upper edge of the first driving device 30 and thus blocks a return of the first driving device 30 to the coupled position of the first driving device 30 and second driving device 40 would. This means that the upper end of the coupling element 62 must not protrude beyond the upper end of the second driving device 40, in particular may not be higher than the uppermost point of the stop ramp 44.

In order to provide a suitable limitation in the Umklappbewegung downward, the first cam means 30, as in particular from Fig. 6 to remove the abovementioned short stop 34 in the form of a stop surface 35. From a synopsis of FIGS. 6 and 8 can be the folding operation of the leaf springs 72, 74 at the transition of the coupling device 60 from the locking position ( Fig. 6 ) in the unlocked position ( Fig. 8 ) comprehend. In the in Fig. 8 shown situation, the leaf springs 72, 74 are at least partially on the stop surface 35, which prevents further folding. Furthermore, the connection points of leaf spring 72, 74 to the coupling element 62, ie in the region of the second end 78, below an imaginary line connecting the two grooves 36, 37 and the first ends 76. In a corresponding manner, the above-mentioned connection points are in the Fig. 6 situation shown above this imaginary connecting line.

In the event of a fault, the user located within the space delimited by the door 140 can perform the following emergency release for at least one opening of the door leaf 100 or, if required, multiple opening and closing of the door leaf 100. In this case, the user is transferred by means of an actuating unit 80, in particular by means of a manually operable drawstring, which is connected to the coupling element 62, the coupling device 60 from the locking position to the unlocked position by pulling on the drawstring. In this process, the coupling element 62 is pulled out of the recess 42 downwards, so that the coupling element 62 is out of engagement with the recess 42.

After the transfer of the coupling device 60 in the unlocked position according to Fig. 8 the first driving device 30 and the second driving device 40 are in a decoupled state. Here, the second driving device 40 is largely fixed due to the self-locking of the door drive 110 with respect to their position along the guide means 120 and therefore can not or only slightly moved.

On the other hand, in the unlocked position according to Fig. 8 For example, the first carrier device 30 can be displaced via the coupling linkage 102 and the first carrier device 30 via a handle 104 attached to the door leaf 100. In this case, a displacement and thus opening or closing of the door leaf 100 both in the direction of the open end position and the closing end position of the door 140 is possible.

Such a situation is then in the Figures 9 and 10 shown. Fig. 9 shows the situation after moving the door leaf 100 and thus the first driver 30 in the direction of the arrow. After a correction of the fault, it is desired that the coupling device 60 back into a State in which the normal operation of the door 140 is possible. For this purpose, the entrainment means 30, 40 must be brought together to form a compact carriage body and connected to each other such that the carriage body 20 is uniformly displaceable along the guide means 120.

For this purpose, starting from Fig. 9 the coupling element 62 by means of the actuating unit 80, such as by means of a rod or manually, at least pushed so far up that the leaf springs 72, 74 fold up and the coupling element 62 in the in Fig. 10 shown position corresponding to the locking position. Now, the first driving device 30 can be moved, for example via the handle 104 and the door leaf 100 in the direction of the second driving device 40. In order to bring the coupling element 62 back into engagement with the recess 62, the second entrainment device 40 has a first stop step 44 and a second stop step 46. This allows the coupling member 62 comes into contact with the first Anschlagrampe 44 and is pressed down as far as the first driver 30 continues to move so far that no folding of the leaf springs 72, 74 occurs, but as soon as the two driver devices 30, 40 on the same Height along the longitudinal direction of the guide means 120 are located, the coupling element 62 as a result of the bias of the leaf springs 72, 74 is pushed up into the recess 42. In this state is then again in Fig. 6 achieved locking position shown, in which the first cam means 30 is coupled to the second cam means 40. Due to the bias of the biasing means 70 in the form of the leaf springs 72, 74, the coupling means 60 is held in the locking position.

Finally shows Fig. 11 a longitudinal section of a driver device 10 according to the invention according to a second embodiment. This forms a Zugmittelkupplung 132, the first entrainment device. The second carrier device is formed by the carriage body 20. The coupling device 60 couples or decouples the traction mechanism coupling 132 with the carriage body. For this purpose, in turn, the above-described devices of the coupling device 60 and the biasing device 70 are used. Thus, the Zugmittelkupplung 132, the recess 42 and the carriage body 20, the channel 38. The biasing device 70 is in turn equipped with the two leaf springs 72, 74 and cooperates with the coupling device 60 in the manner described above.
