Description

The invention relates to a door drive device with the features of the preamble of claim 1 and a door provided therewith.

Door drives are known, for example, for tilting, swinging or sectional doors in the form of drag drives. A driver, which is attached to the door leaf, can be moved in a guide rail between an open position, a closed position and a partial open position. The driver is connected by a traction means, such as a toothed belt, with a driven gear of a transmission. The gearbox is driven by an electric motor and can be self-locking, for example as a worm gear. In the closed state of the door, the door leaf is inhibited solely by the door drive. If the door drive does not have a self-locking gear, the door leaf can be pushed manually. If the door drive is designed to be self-locking, due to the numerous components of the drive train - gear, traction means and driver - there is an immense game and thus no effective protection against pushing the gate.

DE 199 51 289 A1 discloses a gate drive device for a gate which is secured by a locking device against unauthorized opening. The locking device hooks in the closed state of the gate in a closing end stop. If a force is exerted in the opening direction of the door on the door leaf, the entanglement prevents movement of the door leaf. The door leaf can thus be blocked without play in the closed state.

Based on the state of the art DE 199 51 289 A1 The invention has for its object to further improve a device referred to in the preamble of claim 1 with respect to burglary protection.

The object is achieved by a door drive device according to claim 1. Advantageous embodiments of the invention are the subject of the dependent claims.

The door drive device is used to move a door leaf of a gate. The door drive device comprises a motor, a driver and a slide-on safety device. The door leaf can be connected to the driver. The driver is by the motor in an open position in which the door leaf is fully open, in a closed position in which the door leaf is fully closed and in a partial open position in which the door leaf is partially opened for the purpose of ventilation, movable. The slide-on safety device has a locking member for locking the driver in the case of a force exerted by the door leaf on the driver by positive engagement of an abutment member. The push-on safety device has a partial opening bearing member, which allows blocking of the driver in the partial opening position.

Preferably, the door drive device comprises a guide rail for guiding the driver, on which the partial opening counter-bearing member in the position, in particular along the guide rail, can be fastened adjustable.

Preferably, the partial opening interference member has a fixing portion for fixing to the guide rail and a partial opening interference member abutment portion adapted to come into contact with the locking member.

Preferably, the Teilöffnungsgegenlagerglied is designed as a stopper clamp which is clamped to the guide rail and on which the Teilöffnungsgegenlagerglied stop area is provided.

The partial opening interference abutment abutment area may be straight. In particular, the partial opening interference abutment abutment area is provided at an angle to a longitudinal direction of the partial opening interference abutment member.

Advantageously, the locking member is rotatably mounted about a transverse to the direction of the guide rail aligned locking member rotation axis.

Preferably, the locking member has a curved locking member abutment portion adapted to cooperate with the partial opening interference member such that when a force is applied to the driver, the locking member is moved toward the partial opening interference member.

Preferably, the locking member stop region is formed in a circular arc.

It is preferred that the locking member comprises a connecting arm with a mounting device for connecting the door leaf. Further, the locking member may comprise a locking arm for the positive detection of the stop element. In particular, the blocking member abutment region is provided on the blocking arm. Preferably, the locking member has a connecting arm connecting the connecting arm and the locking arm.

Advantageously, the connecting arm and the connecting arm are rotatably supported by a common bolt and in particular connected to each other by the bolt.

The connecting arm and the blocking arm advantageously form an angle between 80 ° and 100 °.

In particular, the locking arm is aligned parallel to the guide rail.

The connecting arm preferably forms an approximately right angle with the blocking arm.

Advantageously, the barrier arm is designed as a pawl, in particular as a double pawl.

The locking member and / or the Teilöffnungsgegenlagerglied may be formed symmetrically with respect to a vertical center plane of the guide rail.

Furthermore, the slide-on safety device can have a closing position counter-bearing member. In addition, the blocking member may be formed for blocking the driver in the closed position at a force exerted by the motor on the driver force by positive detection of the closed position counter-bearing member.

Preferably, the door drive device comprises an emergency unlocking device for manually unlocking the locking device.

According to a further aspect, the invention provides a door, in particular a tilting, pivoting or sectional door, which is provided with a door drive device according to an aforementioned preferred embodiment.

In the partial open position of the door leaf, the driver is located at the position of the partial opening interference member. If no force acts on the door leaf in the opening direction, the locking member is in an unlocking position, in which the partial opening bearing member and the locking member do not engage each other. If an attempt is now made to push the door leaf out of the partial opening position in the opening direction, a force acts on the driver. As a result, the locking member is moved to the blocking position. In the blocking position, the blocking member and the partial opening interference-bearing member engage one another in a form-fitting manner. Further movement of the door leaf in the opening direction is thus prevented.

In a preferred door drive device, the push-on safety device allows blocking of the door leaf even in a partial open position of the door leaf. The gate can thus not be pushed over easily, even if the door leaf, for example, is in a ventilation position. Particularly advantageous is the purely mechanical design of the slip-on protection, which allows reliable blocking of the door leaf even in the event of a power failure.

Further developments of the door drive are directed, for example, to an improvement in the power flow and have, inter alia, advantages described below.

End stops, which are also referred to herein as the closing side and the opening side end stop, prevent further movement of the driver in the opening or closing direction. The locking member is disposed on the driver and consequently moves with this. The partial opening interference member can be fixed along the guide rail between the two end stops in the desired position. In the embodiment as a stop terminal, the partial opening interference member can be clamped to the guide rail.

In some embodiments, the force may be redirected in a direction substantially perpendicular thereto from a direction parallel to the guide rail that would cause movement of the door leaf. Consequently, the blocking effect can be improved because the force acts only in a fraction of the original amount in the opening direction of the door leaf.

When one of the stopper portions is curved, for example, the stopper stopper portion, and the other stopper portion is formed, for example, the partial-opening-buttstock stopper portion, the stopper-member stopper portion may roll upon application of a force on the partial-opening-butt member stopper portion. In this case, the locking member is pivoted in the direction of the Teilöffnungsgegenlagerglied. The force is thus redirected from the opening direction in a direction substantially perpendicular thereto.

A symmetrical design of the slip-on protection can further improve the blocking effect. For example, torques about a vertical axis of the driver can thereby be reduced or prevented, which allows a more uniform distribution of force and thus greater stability.

In particular, known door drive devices can be retrofitted with the slip-on protection. The slip-on protection can be retrofitted in particular for door drive devices that already have a slide-on protection for the end stop, as they are approximately in DE 199 51 289 A1 are disclosed.

An emergency unlocking device allows easy unlocking of the locking device and thus opening the door leaf, for example in an emergency situation.

The gate leaf 16 and according to the driver 26 have a closed position in which the door leaf 16 the room 14 closes, an open position in which the door leaf 16 is fully open, and a schematic in 1 illustrated partial opening position. In the partial opening position is the door leaf 16 so far opened that a ventilation of the area 14 can take place, but no person under the door leaf 16 crawl through and thus into the room 14 can get. This is also called ventilation position.

It will be following on the 2 to 5 Referenced.

At the opening end (in 1 the right end) of the guide rail 24 are an end stop 30 and a fall attachment 32 intended. The door drive device 18 includes a slip-on protection 34 , The postponement insurance 34 prevents sliding of the door leaf 16 when a force F in the opening direction to the door leaf 16 is created.

The postponement insurance 34 includes a partial opening interference member 36 and a locking member 38 for the positive engagement of the partial opening interference member 36 ,

The partial opening interference member 36 is on the guide rail 24 attached. The partial opening interference member 36 can along the guide rails 24 be adjusted in his position.

The partial opening interference member 36 includes a mounting area 40 for attaching the partial opening interference member to the guide rail. Further, the partial opening interference member comprises 36 a partial opening pad bearing stopper area 42 with which the locking member 38 can get in contact.

Preferably, the partial opening interference member is 36 as a stopper clamp 44 educated. The stop clamp 44 is made in the present example as a stamped and bent part made of sheet metal. The stop clamp 44 includes a first abutment clamp area 46 , a second stopper clamp portion 48 , one of the two stop clamp clamping areas 46 and 48 connecting stopper clamp connection area 50 , a stopper clamp application area 52 for applying the stop clamp 44 to a side surface of the guide rail 24 and a stopper clamp blocking member portion 54 , the locking member 38 is facing.

The stopper clamp connection area 50 is bent so that the two stop clamp clamping areas 46 . 48 are substantially parallel to each other and a stopper terminal clamping gap 56 define. The stopper clamp nip 56 can be a projection of the guide rail 24 take up. The stopper clamp application area 52 closes substantially perpendicular to the two abutment terminal clamping areas 46 . 48 extending to the second stopper clamp area 48 at. The stopper clamp locking member area 54 in turn, it closes substantially perpendicular to the abutment clamp application area 52 extending or substantially parallel to the two abutment terminal clamping areas 46 . 48 extending at the abutment clamp application area 52 on, so that one side of the abutment clamp locking member area 54 the second stopper clamp area 48 is facing.

The stopper clamp locking member area 54 has one at an angle to the abutment clamp clamping areas 46 . 48 extending projection 58 on.

The lead 58 is an example of a partial opening pad stop area 42 ,

For attaching the stop clamp 44 this is so on the guide rail 24 arranged that a projection of the guide rail 24 in the stopper clamp nip 56 is included. The stopper clamp application area 52 comes in contact with a surface of the guide rail 24 brought. A stopper clamp clamping bolt 60 For example, a threaded bolt 62 , is through openings in the two abutment clamp areas 46 . 48 plugged. A threaded nut 64 is on the threaded bolt 62 tightened. In the present example is additionally a washer 66 intended.

By tightening the threaded nut 64 becomes the stopper clamp 44 non-positively on the guide rail 24 attached. In the present example, the partial opening interference member comprises 36 a second stop clamp 68 symmetrical to a vertical median plane of the guide rail 24 opposite the stop clamp 44 is attached.

The locking member 38 is a locking member rotation axis 70 rotatably mounted. The locking member rotation axis 70 is transverse to the longitudinal direction of the driver 26 aligned.

In the present example, the locking member comprises 38 a locking member abutment area 72 , The locking member stop area 72 may be the partial opening interference member 36 capture positively. The locking member stop area 72 is preferably curved, in particular circular arc, formed.

The locking member 38 further comprises a connecting arm 74 with a mounting device 76 for connecting the door leaf 16 , In addition, on the locking member 38 a barrier arm 78 for detecting the partial opening interference member 36 and a connecting arm 74 and the blocking arm 78 connecting connecting arm 80 intended.

The locking member 38 is for example made as a stamped bent part of sheet metal. When installed, the connecting arm extends 74 away from the locking member rotation axis 70 , The mounting device 76 For example, it is formed by openings on which a connecting gear rod, not shown here, can be fastened.

The connecting arm 80 extends from the locking member rotation axis 70 in a transverse direction of the driver 26 , so that when installed, an edge of the guide rail 24 surmounted. Preferably perpendicular to the connecting arm 80 closes the barrier arm 78 in the installed state substantially parallel to the guide rail 74 runs.

The connecting arm 74 , the barrier arm 78 and the connecting arm 80 are integrally formed in the present example. In a modification, the arms can 74 . 78 . 80 However, also be formed in several pieces.

The following is an example using 5 the contour of the barrier arm 78 described. The barrier arm 78 is formed like a hook. A first barrier arm section 82 is substantially straight along the extension direction of the locking arm 78 , Subsequently, a second Sperrarmabschnitt runs 84 which is formed in a circular arc with a first radius R1. A third barrier arm section 86 closes to the second Sperrarmabschnitt 84 and is also formed in a circular arc with a radius R2. The second radius R2 is smaller than the first radius R1. An adjoining fourth barrier arm section 88 is at an angle to the first barrier arm portion 82 , After a rounded transition 90 followed by a fifth Sperrarmabschnitt 92 substantially parallel to the first barrier arm portion 82 runs. The barrier arm 78 is thus hook-like as a pawl 94 educated.

The pawl 94 however, is not limited to the specific shape described above. Other embodiments, the form-locking detection of the Teilöffnungsgegenlagergliedes 96 allow are also possible.

In addition, the locking member 38 with a closing position locking hook 96 be equipped. The closing position lock hook 96 blocks the driver 26 in the closed position, by the closing position locking hook 96 at one on the guide rail 24 provided closing position counter-bearing member 98 hooks.

In the present example, the blocking member 38 also symmetrical to the vertical median plane of the guide rail 24 or the driver 26 educated. The locking member 38 thus forms a double locking hook 100 ,

The operation of the door drive device will be described below 18 described.

In the open position of the door leaf 16 is the room 14 accessible to people. The driver 26 is located on the opening-side end stop of the guide rail 24 , The postponement insurance 34 is inactive in the open position.

Is the door leaf 16 in the partial opening position is the driver 26 . more precisely, the locking member 38 at the position of the partial opening interference member 36 , In the partial opening position, people can use the room 14 Do not enter. The space 14 is still ventilated.

Will now try the door leaf 16 postpone in the open position, the slip-on protection 34 ,

The on the door leaf 16 in the opening direction applied force F is on the connecting rod 28 in the locking member 38 initiated. The locking member 38 thus becomes the locking member pivot axis 70 turned that double lock hook 100 the partial opening interference member 36 positively detected.

Due to the rotational movement, the outside of the door leaf 16 applied force F in a direction perpendicular to the guide rail 24 be redirected. It then acts only a fraction of the force F along the direction of movement of the driver 26 , In addition, the curved configuration of the barrier arm allows 78 rolling on the partial opening interference member 36 , The driver 26 can additionally in a direction perpendicular to the longitudinal direction of the guide rail 24 tilt.

Thus, a postponement of the door leaf 16 be prevented.

The locking member 38 forms a two-armed lever. The connecting arm 74 and the barrier arm 78 each form a lever arm. As the force F increases, the connecting rod becomes 28 moved further in the opening direction. The locking member 38 is further by the force F to the locking member rotation axis 70 in Verhakrichtung (in 5 clockwise). The positive connection of the locking member 38 with the partial opening interference member 36 is thus further enhanced with an increase in the force F.

Is no more power to the door leaf 16 put on, pulls the weight of the door leaf 16 the locking member 38 from the form-fit, as in 5 shown, leaving the door leaf 16 as usual with the help of the door drive device 18 can be moved.

In the closed position, the closing position locking hook detects 96 the closed-position counter-bearing member 98 , The closing position lock hook 96 can so on the locking member 38 be provided that he always in the opposite direction to the barrier arms 78 is moved. This means that when closing the driver 26 the door leaf 16 in the closed position presses. The motor 22 drives the driver 26 however, continue toward the closed position, allowing a drive force through the mounting device 76 in the connecting arm 80 is initiated. The locking member 38 then pivots about the locking member rotation axis 70 and the close position lock hook 96 detects the closing position interference member 98 ,

The locking member 38 forms a two-armed lever. The connecting arm 74 and the close position lock hook 96 each form a lever arm. Will now tried from the outside the door leaf 16 postpone in the opening direction, the force F acts such that the locking member 38 continue with the closing position counter bearing member 98 is hooked. The locking member 38 becomes at an increase in the force F, similar to the part opening position, further to the locking member rotation axis 70 in Verhakrichtung (in 5 clockwise). The positive connection of the locking member 38 More specifically, the closing position locking hook 96 with the closing position counterpart member 98 is thus further enhanced with an increase in the force F.

In addition, the structure and operation of the Schließstellungssperrhakens 96 and the closing position pusher member 98 to the aforementioned DE 199 51 289 A1 directed. In particular, known Torantriebsvorrichtungen with the slip-on 34 be retrofitted. The postponement insurance 34 can be retrofitted in particular with door drive devices that already have a slide-on protection for the end stop, as in about DE 199 51 289 A1 are disclosed.

The door drive device 18 with the push-up protection 34 can the door leaf 16 move between the closed position, the open position and a partial open position. In the closed position and the partial opening position, the slip-on protection 34 prevent the door leaf 16 can be pushed by an externally applied force F. Thus, unauthorized persons can enter the room 14 be denied.
