Description

Gate, in particular sectional door, and door drive device

The present invention relates to a gate, in particular a sectional door, with a door leaf which can be moved from an open end position into a closed end position. For controlling the door drive, a control unit is provided. The invention further relates to such a control unit, a locking device for locking / unlocking a door leaf and a door drive device.

The term "open end position" is understood to mean the end position of the door leaf at the end of the opening movement, and the closing end position is the end position at the end of the closing movement.

In particular, with sectional doors openings of buildings, garages and the like are closed. In order to achieve an air exchange with the environment in the fully closed state, ie in the closing end position, various types of ventilation systems are used.

On the one hand, it is known to provide the top panel in the closed state (also referred to as section) with ventilation slots. On the other hand, the lowermost panel may be provided in the region of its closing edge with a combined sealing and ventilation profile, wherein a flow channel is formed in the profile. In addition, numerous ventilation systems are known in which the top panel is folded away in the closing end position by a pivoting movement inwards.

Thus, from DE 20 2005 008 027 U1 a sectional door is known in which an independent power drive is provided for pivoting the topmost panel with the door closed. This solution proves to be disadvantageous in that on the one hand a detailed trained pivoting mechanism and on the other hand next to the drive to open and close the door leaf, another drive for pivoting the top panel is required.

The invention has for its object to provide a gate with a simply designed ventilation system. Furthermore, for this purpose, a suitable control unit, a door drive and a locking device should be specified.

To achieve this object, the aforementioned gate according to claim 1, characterized in that the control unit has a ventilation control device for targeted automatic control of the drive such that the drive moves the door leaf in a predetermined, located between the Offenendstellung and the closing position ventilation position ,

A suitable for such a gate control unit, a locking device and a door drive device are the subject of the additional claims.

An idea of the invention is thus to bring the door leaf in a ventilation position that the already existing drive for drive the door leaf is also used to move the door leaf in a ventilation position.

The predetermined ventilation position is preferably a position close to the closing end position, where the door is open so far that an exchange of air can take place, but continues to be closed so far that access or access through the door opening is still avoided.

Accordingly, in the case of a door designed in accordance with the invention, no mechanical pivoting mechanism for the uppermost panel, no additional drive or an elaborately constructed lowermost panel is required. Furthermore, the ventilation control device can be realized in a simple manner and can be integrated into the already existing control unit for the drive. It is also possible to replace a conventional control unit or to add the ventilation control device.

In a preferred embodiment, the control unit comprises a memory unit in which at least one ventilation position is programmed. It is also possible to predetermine several ventilation positions or a ventilation area. The at least one ventilation position or the ventilation position range can be determined during installation of the door and stored in the storage unit or automatically entered or programmed after installation of the gate by the user as needed. For example, the ventilation Stuhgen can be entered by means of a keyboard on the control unit directly or via a wireless or wired input unit or taught by means of a learning mode. For example, the ventilation settings can be user-defined, temperature-dependent, season-dependent or daytime-dependent. Advantageously, the ventilation control device can be controlled via a switching device. Preferably, the switching device is fixedly mounted in the region of the gate or by a mobile transmitting unit (remote control). forms. For example, a hand-held transmitter for remotely controlling the door has a plurality of operation keys, at least one of which is for initiating a "normal" door movement, where the door moves into one of the end positions, and at least one for moving the door into a ventilation position.

It is already known and customary to avoid limit switches in gate drives the distance traveled z. B. by means of incremental encoders and counters to record and the two end positions corresponding counter readings in a (usually non-volatile) memory. With such a door drive, it is very easy to implement, still a third position, namely to capture the ventilation position and store. It is also easy to program a meter reading range - for example, from the closing end position to a maximum ventilation position - within which several ventilation positions can be selected. Instead of a control over the route and a control over time is possible. Such can be done without an incremental encoder. For the ventilation position can be programmed to stop the opening run after a short predetermined time again.

A preferred embodiment is that in the ventilation position, a first gap between a first closing edge of the door leaf and the bottom of the door opening is present. For this purpose, it is expedient if the ventilation control device is set up in such a way that the (maximum) clear width of the gap can be programmed into the memory unit.

According to a further preferred embodiment, a second gap between a second closing edge and an upper horizontal boundary of the door opening is present in the ventilation position. In this position, there is at least a portion of the door leaf, preferably the top panel, in a pivoted from the door opening plane position. This position arises in the case of a sectional door anyway as a result of the Migen leadership held upper guide rollers of the top panel or by the connected to the top panel drive rod and thus requires no additional mechanics. Even with a single-leaf overhead door leaf, such a ventilation position can be realized on the basis of the already existing mechanics. Particularly advantageous is a ventilation position in which the first and the second gap are present, ie a gap between the lower closing edge and the bottom and a gap between the upper closing edge and the upper horizontal boundary is given. This position can also be referred to as Umluftstellung because it allows air circulation. For example, (warmer) air can flow out of the space enclosed by the gate into the environment via the upper gap, while through the lower gap z. B. (colder) "fresh air" from the environment flows inward.

Preferably, the door leaf is designed as a sectional door leaf and therefore has a plurality of articulated hinged to each other sections or panels. In such a design as a sectional door, the first gap between the lowermost panel and the floor and the second gap between the uppermost panel and the upper horizontal boundary would be present in the ventilation position. This results automatically in conventional sectional doors with arcuate guides between the closing end position and opening end position when the door leaf is moved a few centimeters from the closing end position in the opening direction and stopped there.

Many door drives are designed to be self-locking, so that they even in the de-energized state, the door leaf z. B. hold in the final closing position and counteract burglary attempts. However, self-locking is not always sufficient to withstand brute force, such as chisels. It is therefore already known to provide for locking the door leaf in the closing position further locks. For example, from EP 1 187 963 B1 a door drive with Sperrvorrich- known. The locking device is associated with a transmission element of the door drive. The locking device is active in the closing end position and prevents movement of the door leaf, if acting by a force acting on the door leaf in the closing direction. In contrast, the locking device releases automatically when the opening force emanating from the door drive. Although such locking devices have proven excellent in practice, so it is difficult to achieve a lock in the ventilation position. Although the Lüftungsstellungs- control invention has great advantages in terms of their simplicity and thus much cheaper than previous ventilation devices is feasible and also has advantages in terms of better air exchange, so this ventilation position still offers a possible point of attack for burglary attempts.

In a further preferred embodiment, therefore, a locking device is provided which prevents movement of the door leaf from the ventilation position or a position between the closing end position and the ventilation position beyond the ventilation position in the direction of the open end position. In other words, the door leaf may be locked against opening so that, although it is movable between the Schließendstellung and the (maximum) ventilation position, but not beyond. Basically, it is sufficient to prevent unauthorized access that an opening movement of the door leaf over a point associated with the ventilation position is not possible, since the ventilation gap is usually only a few centimeters.

To secure the door leaf in the ventilation position against burglary, the locking device is positioned at a predetermined distance from the closing edge of the door leaf. In this way, unauthorized unlocking of the locking device can be prevented. In an advantageous embodiment, the locking device comprises a locking element which can be adjusted from a locking position into an unlocking position and a locking device. Lock element and locking device are in the locking position in operative connection, that the locking element is locked by the locking device so that a movement of the door leaf is only possible between the ventilation position and the closing end position. This is achieved, for example, in that the locking device acts as a stop for the locking element brought into the locking position.

Furthermore, the locking element on the door leaf or fixedly arranged and the locking device may be fixed or mounted on the door leaf, the / attached to the door leaf locking element / locking device in the final closing position of the door less far from the ground than the / fixedly mounted locking device / locking element is, so that locking element and locking device only come into operative connection in the ventilation position of the door leaf. For example, the locking element is present on the door leaf and the locking device is fixed in place at a corresponding point of the Torblattberandung. Of course, the locking device could also be arranged mitbewegend on the door leaf and the locking element is then arranged stationary.

In one embodiment, the locking element in the unlocked position can simply be withdrawn in such a way that it can be moved relatively unhindered past the locking device when the door leaf moves from the ventilation position into the opening end position and vice versa. In the unlocked position, however, the locking element preferably assumes a position such that it can come into operative connection with the locking device. This happens when the door leaf and thus the locking element is moved in the direction of the locking device. The operative connection is preferably used in a movement of the door leaf in the closing direction in one of possible ventilation positions to move the locking element from the unlocked position into the locking position. This happens, for example, in the following manner: as a result of the impact of an outer edge of the locking element on the locking device, preferably a stop pin, the locking element is pivoted into the locking position. Furthermore, it can also be provided that the locking position is assigned exclusively to the ventilation position, ie that the door leaf is locked in the ventilation position such that it is not movable in any direction.

Preferably, the locking element comprises a rotary latch, which is pivotable, for example, about an approximately horizontal, in particular parallel to the door opening plane extending axis of rotation.

Preferably, the locking element is held in the unlocked position by means of a latching device and when moving the door leaf in the closing direction in an end region near the closed position, where possible ventilation positions can be moved from the unlocked position by overcoming the locking device in the locking division.

In an advantageous embodiment, the rotary latch for this purpose has a control recess with a latching point and a recess. In this case, a locking element is held in the locking position in the recess and in the unlocked position in the rest position. Furthermore, the rotary latch is pivotable as a result of the movement of the door leaf by means of the guided in the control recess locking member from the locking position to the unlocked position. The latching point is preferably formed in the form of a depression or depression at one end of the control recess.

The locking element is advantageously a Schnepperbolzen which can be acted upon with a bias. The locking element can have a jump, which is locked in the locking position by the locking device on a movement past the locking device.

The locking device is preferably designed as a stationary stop, suitably as a stop pin. Such a bolt is preferably aligned parallel to the door opening plane and has a bolt head, which engages behind the rotary latch, in particular the locking projection, such that a movement of the door leaf is prevented or at least limited transverse to the opening and closing movement.

For the adjustment of the locking element, an (automatic) signal-controllable actuating unit, preferably an electromagnet, is advantageously provided. As a result, the locking device can be controlled by the door drive, in particular the control unit.

The locking element is preferably one of the locking position of the locking element associated blocking position, in one of the unlocked position of the locking element associated release position and in a rotational position can be brought. The rotational position serves to bring the locking element from the locking position to the unlocked position and vice versa. In one embodiment of the locking element as a rotary latch with control recess, latching point and recess, the locking element is in the blocking position in the recess and is held there. In the rotational position, the locking element is guided in the control recess. In the release position, the locking element is engaged with the latching point.

In one embodiment, biased in the blocking position locking element can this bring by the Signalansteuerbarbetätigungseinheit from the locked position into the rotational position. Then the rotary latch can be rotated by movement of the door leaf by means of the door drive and attack on the stop pin acting as a locking device, so that the Locking element is no longer aligned with the recess. Then, the actuator unit can release the locking element, so that this engages in the control recess. Upon further movement of the rotary latch, the locking element slides in the control recess to the rest stop. When closing movement of the rotary latch in turn comes with the locking device in operative engagement and is rotated in its locking position. In this case, the prestressed locking element slides out of the rest position first into the control recess and finally into the recess. In this way, only once, for unlocking the locking device, the actuator unit must be pressed briefly. All other functions are mechanical and can be done without power.

In order to bring the locking device (eg power failure) from the locking position into the unlocked position in an emergency situation, an emergency unlocking device is provided. This can preferably be operated manually. For example, this is to pull the aforementioned locking element against its bias by hand from its locked position and then to open the door leaf manually.

To achieve the above object is in accordance with claim 24, a door drive device for moving a Torblattes between a Offenendstellung and a closing end position with a motor drive unit, a guide device, a movable by the motor drive unit along the guide means driver and a connection device for connecting the door leaf with the driver intended. Furthermore, the door drive device comprises a locking unit for locking the door leaf in the region of a ventilation position located between the open end position and the closed end position, so that the door leaf is locked against movement when there is no force exerted by the driver. In other words, the locking unit is only at Einbruchsbzw. Opening attempt, ie brought in an outgoing from the driver force, in a locking position. This takes place at a certain force, which is also used to bring the locking unit in the locked position. However, since this requires a certain force or a certain displacement of the door leaf in the direction of the open end position, for example to overcome the weight of the door leaf and / or the force exerted by the self-locking, the locking takes place "in the area" of the ventilation position be provided that in the ventilation position, a gap of for example 10 cm between the bottom and the lower closing edge of the door leaf is present and the locking position of the locking unit is reached when the lower closing edge of the door leaf as a result of the force at a distance of about 15 cm from the floor to the nursery bed and thus locked against further opening.This "buffer path" of 5 cm is preferably taken into account in determining the maximum gap between the closing edge and the floor to prevent a person or any tool from passing through the gap ge long to open the door leaf.

An advantage of this solution is primarily in the fact that the locking unit is transferred only in the event of a break-in attempt in the locked position and remains in the unlocked position in the absence of action on the door leaf, so that the door leaf can be moved from the ventilation position to the Schließendstellung or the Offenendstellung , without first the locking unit must be operated. Another advantage is that the force acting on the door leaf during the attempt to break in can be used to transfer the locking unit from the unlocked position into the locking position. In this way, no separate drive must be provided for this purpose. In a preferred embodiment, the locking unit comprises a locking unit and a locking unit, wherein the locking unit is adjustable by a force from a release position to a locking position and the locking unit releases the locking unit in the release position and locks in the blocking position. Thus, the acting force or the displacement of the door leaf is advantageously transformed by means of a translational and / or rotary mechanism in a translational and / or rotational movement of the locking unit. Such a mechanism can be constructed of few and simply constructed components, has a long life and usually requires no maintenance.

Preferably, the locking unit is connected via a spring unit and a coupling unit to the connecting device, wherein spring unit and coupling unit cooperate such that from a certain force and / or a certain displacement by the movement of the door leaf, the locking unit is adjustable in the locked position. In a preferred variant, the locking unit is space-saving attached to the connecting device, preferably on a push rod for connecting the door leaf with the driver. This results in the further advantage that the locking unit is far away from the lower closing edge of the door leaf and thus difficult for any through the ventilation gap introduced burglary tool can be reached. Furthermore, the locking unit can be mounted in advance on the connecting device (eg push rod), whereby locking unit and connecting device can be delivered as a prefabricated component to the installation site and only the locking unit must be positioned according to local conditions. If the spring unit is involved in such a design that it is only claimed when the locking unit must be adjusted to the blocking position, that is, when it comes to an unauthorized opening attempt, a permanent load on the spring unit is avoided. Advantageously, the locking unit is rotatably connected to the coupling unit. Furthermore, it is advantageous if the coupling unit is displaceably connected to the connecting device along the connecting device. In this case, the coupling unit serves primarily as a sliding guide and transforms the longitudinal displacement of the push rod preferably in a rotational movement of the locking unit. Preferably, the locking unit is rotatable about an axis parallel to Torblattebene axis, in particular pivotable.

In order to realize a simple interaction of locking unit and coupling unit, the locking unit has a first control recess and the coupling unit has a second control recess, wherein the locking unit and the coupling unit are operatively connected to one another via a control pin forcibly guided in both control recesses, in particular a control bolt Moving the door leaf in the direction of the open end to transform into a movement of the locking unit in the locked position. Preferably, the first control recess and / or the second control recess has a first end and a second end, wherein the first end of the locking position and the second end is associated with the release position of the locking unit.

In order to be able to absorb forces transversely to the direction of movement of the door leaf and to provide for a symmetrical removal of force, the locking unit is fork-shaped with at least two lever arms. Accordingly, the locking unit may be formed.

According to a further preferred embodiment, the spring unit comprises a compression spring, which is biased against the coupling unit. Preferably, the degree of damping of the spring unit is variably adjustable. This is done, for example, in that a stop for the spring unit is infinitely variably fastened to the connecting device. alternative infinitely variably fastened to the connecting device. Alternatively, different spring units of different degrees of damping can be provided and mounted depending on the installation situation.

Advantageously, the coupling unit has an opening for a Drehachsstift as the axis of rotation of the locking unit. Preferably, the coupling unit is designed in the form of a housing and has two holes in two opposite housing walls for forming this opening.

On the one hand to couple the door leaf to the driver and on the other hand to contribute at least a partial function as a locking unit, the connection unit is formed by at least two rigid connecting elements which are coupled via the spring unit and the coupling unit. Thus, a first connecting element may be rotatably coupled to the driver and at the other end rigidly attached to the coupling unit. Furthermore, the second connection element can be rotationally coupled to the door leaf and the other end longitudinally displaceable, i. be movably connected in the extension direction of the connecting element via a pressure spring arranged around the first connecting element. Furthermore, the compression spring can be fixedly attached to a housing wall of the coupling unit and fixed to the other end via a variably fixable stop on the first connecting element. In this way, the connecting means by means of the coupling unit and the spring unit in addition to the function for moving the door leaf can be used simultaneously as a connection for the locking unit.

In order to enable a space-saving arrangement, in a further advantageous embodiment, at least one of the connecting elements is guided in sections in the coupling unit. Further preferably, the Connecting device on a recording in which the control pin is held. Appropriately, the receptacle is designed such that the control pin extends transversely to the direction of movement of the door leaf. It is also advantageous if the connecting device designed as a push rod and the receptacle as a receiving opening in the push rod.

As regards the barrier unit, it is preferably fixed in place. Thus, the barrier unit can basically be attached to the ceiling of a garage. However, it is advantageous if the locking unit is attached to the guide device, in particular a door drive rail, whereby the locking unit does not have to be mounted separately on site, but can be attached to the guide device in the factory at this.

Furthermore, it is expedient if the locking unit is detachably fixable at a certain distance from the locking unit. This distance depends primarily on the desired width of the ventilation gap. At this distance, the buffer path described above can be integrated. Conveniently, the locking unit is variably fastened along the guide device, in particular on a guide rail. This results in the advantage that after installation of the gate in the building opening to be closed only a longitudinal displacement of the locking unit on the door drive rail done so far, until the locking unit has reached the fulfillment of locking / unlocking function at the correct position.

In order to be able to fulfill the blocking function in the simplest manner, the blocking unit has at least one stop, in particular a stop ramp. In the event that the locking unit is mounted on the guide rail, and the locking unit is fork-shaped equipped with two lever arms, the stop or the Anschlagrampe can also be arranged on both sides of the guide rail. Preferably, the stop is attached to the upper flange of the guide rail, so that a pass drive of the driver remains possible in order to be able to move the door leaf beyond the ventilation position in the direction of the closing end position or beyond the ventilation position in the direction of the open end position.

In a further preferred embodiment, at least one further blocking unit is provided, which is assigned to a further ventilation position and / or the closing end position. In this way, a single preferably attached to the connecting device locking unit cooperate with a plurality of locking units, so that not a separate locking unit is required for each locking unit.

The above object is also achieved by a gate, in particular a sectional door, with a door leaf and a door drive device according to one of claims 24 to 44.

Fig. 1 shows a gate according to the invention in the form of an upwardly, over head opening sectional door in a ventilation position. The lower part of the lowermost panel 14 forms a closing edge 18. The upper edge of the uppermost panel 14 forms an opening edge 19. In the shown ventilation position, a first gap is between the closing edge 18 and the bottom 20 and between the opening edge 19 and the upper horizontal end of the door opening, a second gap 21 is present. In the example shown, the two gaps 20, 21 each have a width of a few centimeters, for example 3 to 9 cm, in particular 5 cm. This position can also be referred to as Umluftstellung, as a result of the two column 20, 21 air circulation between the room and the environment is possible. examples For example, fresh air enters the room via the first gap 20, while air that has risen upward through the second gap 21 can flow upwards into the environment.

In order to close and open the door opening, the door leaf 10 is movable by means of a door drive 30 via a guide 12 from an open end position to a closed end position. For this purpose, in the region of the upper opening edge 19, an arm 34 engages the uppermost panel 14. The arm 34 is coupled to a ceiling mounted gear device 32 and transmits the movement of the gear device 32 to the door leaf 10. The guide 12 has two guide rails, which are each divided into a vertical, an arcuate and a horizontal portion. In these guide rails connected to the panels 14 guide rollers are guided.

For controlling the door drive 30, a control unit 40 is provided which comprises a ventilation control unit. The ventilation position is programmed in the ventilation control unit. Further, a switching device 50 is attached to the side wall. The switching device 50 is used here to control the ventilation position. Next, a remote control 52 is provided for remote control of the door drive 30. The hand-held transmitter has a first operating key 54 for the initiation of an opening movement of the door leaf 10 from the closing setting into the opening setting. Next, the remote control on a second control button 56 for controlling the ventilation position. The hand-held transmitter is in a customary manner with a receiver 42 associated with the control unit 40 in wireless communication connection.

In order to secure the door leaf 10 in the ventilation position shown in Fig. 1, a locking device 100 is provided. To protect against burglary, the locking device 100 is at a distance from the Positioned closing edge 18 and the ground away, which is sized so large that you can not reach the locking device in encompassing the closing edge from the outside even in the ventilation position. The locking device 100 can be brought from an unlocking position (see FIG. 2) into a locking position (see FIG. 3) and vice versa and for this purpose comprises a locking element 110, a locking device 130 and a locking device 150. The aforementioned components will be described below with reference to FIGS 5 explained in more detail:

Trained as a rotary latch 110 locking element is pivotable about a parallel to the gate opening plane extending horizontal axis 122 from the unlocked position into the locking position and vice versa. The rotary latch 110 has a projection 120 which can be brought into operative connection with the locking device 150. The locking device 150 is designed as a stationary stop and has a horizontally projecting from a side wall stop pin 152. Furthermore, the rotary latch 110 has a control recess 112 (FIG. 4). In the area of a first end of the control recess 112, a recess in the form of a perforation 114 and in the region of a second end a latching point in the form of a trough 116 is provided (see FIG. 4). The perforation 114 is associated with the locking position and the trough 116 of the unlocked position.

The locking device 130 is attached via a bracket 136 to the door leaf 10. For this purpose, a connecting element 138 consisting of an angle-shaped steel profile is screwed to a panel 14 with a profile limb. The other profile leg extends at right angles thereto and is aligned parallel to the rotary latch 110. Locking device 130 and rotary latch 110 can be coupled to one another via a locking element in the form of a horizontally movable Schnepper pin 132. The holder 136 also has a hollow cylindrical sliding guide 140, in which the Schnepperbolzen 132 is guided. To facilitate adjustment of the Schnepper pin 132, an actuator 144 is provided which includes a push rod 148 and an electromagnet 146.

When the door leaf 10 is now moved from the open end position into the ventilation position (see arrow A in FIG. 2), the locking device 100 is initially in its unlocked position. In this position shown in Fig. 2, the standing by means of a spring unit 142 biased Schnepperbolzen 132 is locked with its rounded locking head 134 in the trough 116, whereby the rotary latch 110 is held in its unlocked position.

If now the door leaf 10 moved further in the direction of the closing end position (direction A), abuts an edge 124 of the rotary latch 110 against the stop pin 152, whereby the rotary latch 110 is rotated counterclockwise. Due to the force exerted on the stop bolt 152 on the rotary latch 110 when the edge 124 strikes against the force, the latching head 134 is pressed out of the recess 116 into the control recess 112 and is held in the control recess 112 as a result of the prestressing acting on the snap bolt 132. During the further rotational movement of the rotary bolt 110, the Schnepper bolt 132 is guided along the control recess 112 until it snaps into the perforation 114 in the region of the other end of the control recess 112. This position corresponds to the locking position and is shown in Fig. 3. Now, the rotary latch 110 is in a fixed position by the Schnepperbolzen 132, in which the projection 120 farther away from the door leaf 10 is as the stop pin 152. As a result, the door leaf in the case of movement in direction B is only so far displaced to the projection 120 hits the stop pin 152. The ventilation control unit is set up such that the door leaf 10 can subsequently be moved in direction B according to the method in direction A and reaching the position shown in FIG. 3 until the stop pin 152 engages with the groove 118 of the rotary latch 110. Now the door leaf 10 has reached the maximum ventilation position. The locking device 100 is still in the locked position. In one embodiment, only the maximum ventilation position is stored in the ventilation control unit. If the operator then wants to move from the closed end position into the ventilation position, he only needs to briefly press the second operating button 56. The door leaf then moves directly from the final closed position in the ventilation position. In a further embodiment, the maximum ventilation position is stored in the ventilation control unit. By pressing the second operating button, the door drive can then be moved steplessly between the closing setting and the maximum ventilation position. When the second operating button 56 is released, the door drive stops in a position between the maximum ventilation position and the closing end position. This makes it possible to influence the size of the two gaps 20, 21.

In order to be able to move the sectional door out of the ventilation position in the direction of the open end position, the electromagnet 146 is first actuated when the first operating key is actuated. Characterized the Schnepperbolzen 132 is moved so far in the direction C that it is partially pulled out of the hole 114, but only to the extent that the locking head 134 is not completely out of engagement with the rotary latch 110. The extraction takes place only to the extent that the locking head 134 is completely pressed out of the perforation 114 and into the control recess 112 on further start-up of the door leaf 10 in direction B upon impact of the projection 120 on the stop pin 152 and the rotation of the rotary latch 110 generated thereby , The locking head 134 is now in the control recess 112 and in turn is under a bias. After the rotary latch 110 has passed the stop pin 152, the rotational movement of the rotary latch 110 is completed and the Schnepperbolzen 132 reaches to the end of the control recess 112 and engages due to the bias in the trough 116 a. Now the rotary latch 110 is again in the unlocked position, so that the door leaf 10 can be moved completely into the open end position or in any other desired position.

As usual, the initiation of the closing movement from the open end position can take place automatically after the expiry of a preset opening time.

In the above embodiment can further be provided that the door leaf 10 is locked in the closing end position by means of the door drive 30, so that no further locking device is necessary.

The locking device 150 comprises a provided at the free end of the stop pin 152 bolt head 154 which is dimensioned so that it can engage behind the rotary latch 110 in the region of the groove 118. In this way, a movement of the door leaf 10 is prevented parallel to the door opening plane.

For manual release of the door in the ventilation position, the Schnepper bolt can be manually withdrawn. The door drive 30 is provided with a conventional emergency unlocking device, whereby the gear device can be decoupled from a drive head and the door leaf 10 can be moved manually.

FIG. 6 shows a second embodiment of the door according to the invention in the form of a sectional door which can be opened upwards via the head in a ventilation system. tung position. The sectional door includes a door leaf 200 having a plurality of hinged panels 204. The lower edge of the lowermost panel 204 forms a closing edge 208. The upper edge of the uppermost panel 204 forms an opening edge 209. In the illustrated ventilation position, there is a first gap between the closing edge 208 and the floor 210 and between the opening edge 209 and the upper end of the door opening, a second gap 211 available. In the example shown, the two gaps 210, 211 each have a width of a few centimeters, for example 3 to 9 cm, in particular 5 cm. This position can also be referred to as Umluftstellung, as already explained in connection with FIG. 1.

In order to be able to close and open the door opening, the door leaf 200 can be moved by means of a door drive device 230 via a guide device 240 from an open end position into a closed end position. The door drive device 230 comprises a motor drive unit 232, a driver 234 and a traction means for transmitting the force generated by the motor drive unit 232 on the driver 234. For example, the door drive device 230 is in the form of a not completely self-locking worm gear. For the purpose of movability of the door leaf 200, a connecting device 260 engages one end on the uppermost panel 204 and the other end on the driver 234, so that the force generated by the motor drive unit 232 is transmitted to the door leaf 200 via the traction means, the driver 234 and the connecting device 260 can be. A guide 202 for the door leaf 200 is indicated only schematically in Fig. 6 and has two guide rails, which are each divided into a vertical, an arcuate and a horizontal portion. In these guide rails connected to the panels 204 guide rollers are guided.

In order to guide the driver 234, the guide device 240 comprises a horizontal device attached to the ceiling of the space to be closed. Rail 242. The horizontal rail comprises two interconnected steel profiles, each of the profiles having a horizontal upper flange 243 and a horizontal lower flange 244.

For controlling the door drive device 230, a control unit 245 is provided which comprises a ventilation drive unit. The ventilation position is programmed in this ventilation control unit. Further, a switching device 247 is attached to the side wall. The switching device 247 is used here to control the ventilation position. Furthermore, a remote control 248 for remote control of the door drive device 230 is provided. The hand-held transmitter 248 corresponds to the hand-held transmitter 52 according to the first embodiment and also comprises two operating buttons and further devices for wireless communication connection with a receiver 246 of the control unit 245.

In order to secure the door leaf 200 in the ventilation position shown in Fig. 6, a locking unit 250 is provided, so that the door leaf 200 is locked against movement with outgoing from the driver 234 force, as is the case in a break-in attempt.

The locking unit 250 comprises a locking unit 270 and a locking unit 280, wherein the locking unit 270 is adjustable by a predetermined force on the door leaf 200 from a release position to a blocking position and the locking unit 280 releases the locking unit 270 in the release position and locks in the blocking position.

The locking unit 270 is connected to the connecting device 260 via a spring unit 286 and a coupling unit 290. Spring unit 286 and coupling unit 290 cooperate in such a way that, starting from a specific force action and / or a certain displacement by the movement of the door leaf 200, the locking unit 270 is moved into the locking position. is adjustable. The aforementioned basic principle and the individual components required for this in detail are explained in more detail below with reference to FIGS. 7 to 11:

As can be seen in particular from FIG. 7, the blocking unit 280 comprises a stop 282 fastened to the horizontal rail 242 of the guide device 240. This stop 282 comprises two stop ramps 284, which are arranged symmetrically with respect to the horizontal rail 242. The two stop ramps 284 are each inclined at an angle of about 30 ° to about 60 ° to the longitudinal axis of the horizontal rail 242 and formed as a one-piece profile. The detachable attachment of the stopper 282 takes place on the upper flange 243 of the horizontal rail 242. Further, each Anschlagrampe 284 has a side vertically aligned profile section in order to accommodate transmitted by the locking unit 270 transverse to the direction of movement of the door leaf 200. The attachment of the stop 282 to the upper flanges 243 allows the locking unit 280 to provide no limit to the dog 234 and to move past the locking unit 280.

In order to be able to fulfill the function for blocking or releasing the locking unit 270, the locking unit 280 is fixed at a certain distance from the locking unit 270. Due to the releasable attachment of the locking unit 280 on the horizontal rail 242, it is possible after installation of the gate stop 282 along the upper flange 244 to move until the required locking / unlocking distance to the locking unit 270 is adjusted and can then screwed become. In this adjustment must be taken into account that a certain buffer path is integrated in this distance, so that the locking position of the locking unit 270 is reached only when the door leaf 200 has traveled a certain displacement from the ventilation position to the closing end position. This will avoided that the locking unit 250 is transferred at the slightest force in the locked position.

The locking unit 270 shown in greater detail in FIG. 8 is connected in a rotationally movable manner to the coupling unit 290 shown in detail in FIG. 9. The connection is made via a Drehachsstift 295, which is held both in two openings 274 of the locking unit 270 and in two openings 294 of the coupling unit 290. The symmetrically constructed latch unit 270 further comprises two lever arms 275, 276 which can be engaged with the stop ramps 284. In addition, the locking unit 270 has two oppositely disposed control recesses 271 in the form of oblong holes. For the interaction with these control recesses 271, the coupling unit 290 also has two oppositely disposed control recesses 291. Each of the control recesses 271, 291 has a first end 272, 292 assigned to the blocking position and a second end 273, 293 assigned to the release position. In order to enable a longitudinal displacement of the coupling unit 290 relative to the connection device 260, the coupling unit 290 further has a groove 296 and a bore 297 arranged opposite thereto.

The connecting device 260 comprises a first connecting element 262 shown in FIG. 10 and a second connecting element 265 shown in FIG. 11. The generally approximately L-shaped first connecting element 262 has at one end an opening 263 via which the connecting device 260 is connected by means of a Turning pin is rotatably coupled to the driver 234. The other end of the first connecting element 262 is provided with a groove 264 in order to allow a longitudinal displacement of the second connecting element 265 in cooperation with the bore 297 of the coupling unit 290. The end face of this end of the first connecting element 262 is fixedly attached to the coupling unit 290, welded, for example, wherein groove 264 and bore 297 for partially guiding the second connecting element 265 are aligned coaxially.

The coupling between the second connecting element 265 and the coupling unit 290 takes place via a receiving opening 266 in the second connecting element 265 and a control pin 268 held therein, which extends so far transversely to the connecting element 265 that it is guided in the control recesses 271, 291. A further receiving opening 267 of the second connecting element 265 serves for the rotatable coupling of the uppermost panel 204 to the connecting device 260.

In order to enable the locking unit 270 to be pivoted into the blocking position only after a specific force has been applied to the door leaf 200, the second connecting element 265 is connected to the coupling unit 290 via a spring unit 286. For this purpose, a helical compression spring 287 is arranged around the second connecting element 265, wherein one end of the compression spring 287 is fastened to the second connecting element 265 via a stop element 288 which can be fixed variably along the second connecting element 265. This attachment is thus variably adjustable along the connecting element 265, so that different biasing forces of the compression spring 287 set or possibly different compression springs 287 can be used. The other end of the compression spring 287 is supported against a wall of the housing of the coupling unit 290.

In the following, the operation of the door according to the second embodiment will be described in more detail:

All of the changes in position of the door leaf 200 listed below have in common that during a normal operation of the door drive device 230 for the intended operation of the door leaf 200, the locking is always in the release position, as shown in Fig. 6. Only in the case of an unwanted opening attempt or the like, in particular in a break-in attempt, the locking unit 250 is transferred due to the force in the blocking position shown in Fig. 7, whereby the door leaf 200 is locked in the region of this position, in particular in the region of this ventilation position ,

If the door leaf 200 is moved, for example, from the open end position into the ventilation position or from the closing end position into the ventilation position, the control pin 268 is located along the complete travel path in the region of the second end 293 of the control recess 291 and in the region of the second end 273 of the control recess 271 Locking unit 270 is in its release position. Arrived in the ventilation position, the locking unit 270 remains in the release position. The door leaf 200 is held in the ventilation position due to the self-locking of the door drive 230.

Should a burglary attempt take place in the case of a door leaf 200 located in the ventilation position according to FIG. 6 in which the closing edge 208 is attempted to be pushed manually or by means of a tool upwards in the direction of the open end position, the force counteracting the door drive device 230 initially remains a displacement of the door leaf 200 opposite.

However, as soon as an acting force F1 exceeds the force F2 counteracting the self-locking of the door drive device 230 (see FIG. 6), the adjustment process begins in which the locking unit 270 is transferred from the release position into the blocking position. The force F1 acting on the door leaf 200 is transmitted to the second connecting element 265 by means of the rotary axle pin 268. As soon as the force acting in the longitudinal direction of the connecting element 265 is greater than the spring force of the pressure spring 287, the compression spring 287 undergoes compression. This leads to a longitudinal displacement of the connecting element 265, by the partial guidance of the second connecting element 265 in the coupling unit

290 via the groove 296 and the bore 297 and the groove 264 of the first connecting element 262 is made possible. In other words, the coupling unit 290 also serves as a sliding guide.

Due to the longitudinal displacement of the connecting element 265, the control pin 268 held in the receiving opening 266 becomes in the control recess

291 from the second end 293 toward the first end

292 and thus also shifted from the second end 273 in the direction of the first end 272 of the control recess 271. As a result of this translation of the control pin 268 and the axis of rotation generated by the openings 274 and 294, a pivoting of the locking unit 270 about the Drehachsstift 295 counterclockwise upwards. This pivoting process continues until the control pin 268 has reached the second ends 273, 293, as shown in Fig. 7. In this position, depending on how deep the groove 264 is formed, at the same time the front end of the second connecting element 265 abut the bottom of the groove 264.

In this end position of the control pin 268, the locking unit 270 is now in its locking position, that is, the free ends of the lever arms 275, 276 are pivoted so far up that they, although only after a buffer of a few millimeters or centimeters, in the locked position persisting no longer at the stop ramps 284, 285 are movable past. In other words, the door leaf 200 is movable only as far as possible in the buffer path until the lever arms 275, 276 run completely against the stop ramps 284, 285 and the door leaf 200 can no longer be moved in the direction of the open end position. Thus, the locking unit 250 is transferred by simple means from the unlocked position to the locking position and without an additional drove and only in the case of a break-in attempt or the like. During normal operation of the door, the locking unit 250 remains in the unlocked position.

In a further preferred embodiment, in addition to the already explained, the ventilation position associated locking unit 280, another such blocking unit attached to the upper flanges of the horizontal rail 242 and associated with the closing end position of the door leaf 200. In a further variant, further blocking units can be provided, which are assigned, for example, to different ventilation positions.

A further advantage is that the locking unit 280 allows passing of the driver 234 on the locking unit 280 to move the door panel 200 in the desired positions. Furthermore, the locking unit 280 can already be pre-assembled in the production plant during assembly of the door drive device 230, so that only a fine adjustment for attachment to the correct position of the horizontal rail 242 is necessary during the final assembly of the door. Furthermore, due to the far away from the closing edge 208 arrangement of the locking unit 250 as in the ceiling area of a garage or the like, it is also not possible to manipulate the locking unit 250 by means of a burglary tool.
