Description

The The invention relates to a coupling unit for a garage door, in particular Tilting, swiveling or sectional door, that by means of a motor unit via a, with a drive means designed ceiling rail from an open position in a closed position can be moved, wherein the coupling unit within the Ceiling rail is slidably mounted, and a so equipped Gate drive device for a garage door.

In the DE 27 41 539 A1 a pivoting device for a garage door is described, which has a defined below the garage ceiling guide rail for a coupling piece, which is hinged on the one hand by a distance lever with the garage door and on the other hand by an endless traction means on the guide rail along. The endless traction means is releasably locked to the coupling piece, wherein the attachment can be canceled by a provided between the coupling piece and the garage door shutter release member.

Out EP 0 743 416 A1 is a drive device for a along between an open position and a closed position movable back and forth door leaf with a drive motor known. In a drive guide rail, a traction means is arranged, on which a driver is attached, which is connected via a coupling element with the door leaf. Such a drive device is secured against unauthorized opening of the door by the coupling element is designed as a toggle, which in the closed position of the door leaf so indirectly or directly with the drive guide rail so locked that the door leaf is locked in an inadmissible manual opening attempt.

In the DE 199 51 289 C2 there is disclosed a locking device and a door drive device provided therewith. Here, a lever element is used which has two pivotable about a first pivot axis lever arms and which is hinged to the first lever arm, the connecting element, wherein on the second lever arm, the engagement means for detecting the abutment element is present.

Of the indicated prior art makes it clear that an adaptability to various installation situations with the means shown there sometimes very difficult. This applies in particular for corresponding Lever constructions, in particular only a certain Abwinkelungsmaß the connecting rod allow.

It Therefore, the object of the invention is a coupling unit for a garage door, In particular tilting, pivoting or sectional to create, in the a coupling unit independent is used by a lever construction, wherein the coupling unit should be controlled by the action of a motor unit. Further should be a possibility of manual operation be given.

Is solved the object by the features of claim 1 and by a door drive device according to claim 20. The dependent claims give it a further embodiment of the inventive concept again.

Around the burglar resistance of motor-driven garage doors, In particular tilt, swivel or sectional doors to increase, is proposed according to the invention to place a coupling unit inside a ceiling rail. The coupling unit offers the possibility of blocking the Garage doors, in particular tilt, swivel or Sektionatores in to reach the closed position or offers at the same time the possibility at a wanted opening the garage door or the like that by a drive means, that is driven by the motor unit, an unlocking purposefully performed becomes. Furthermore, it is possible via a manual operation a decoupling of the drive means from the garage door or the like perform.

In order to achieve a safeguard against unintentional opening of the garage door or the like, the coupling unit has a latching hook, which engages in at least one recess within the ceiling rail. The coupling unit, which is arranged displaceably within the ceiling rail, preferably has three adjacent chambers, wherein the middle chamber for receiving the latching hook and a locking pin is used and serve the two lateral chambers for receiving and carrying the drive means. The drive means is endlessly circulating and is preferably driven at one end by the motor unit and guided at the other end via a deflection roller or a wheel within the ceiling rail. On one side, the ends of the drive means are connected to each other via a drive means connection. The drive means connection has a recess which cooperates with the locking pin of the coupling unit. The locking pin is square or rectangular and slidably mounted within the coupling unit. Due to its spring load, it is always pressed into the blocking position, ie it slides into the path of the drive means with the drive means connection. In the closed position of the garage door or the like thus engages the locking pin in the recess of the drive means connection. In this case, the drive means connection is provided with a recess which is substantially longer or larger is formed as the dimensional extension of the locking pin.

Further is located on or at the drive means connection a driver, which cooperates with a starting bolt which is attached to the latching hook. When starting the drive means by the motor unit is so a pivoting of the two-armed lever formed latching hook causes, namely in that the starting bolt in the region of the driver of the Drive means connection comes and thus a pivoting of the latching hook causes. While This stroke of the drive means remains the coupling between the locking pin and the recess is present within the drive means connection, so that in the subsequent other methods always maintain this connection becomes.

During the Starting bolt comes in the region of the driver on the drive means connection, the two-armed latch hook is pivoted, which at the same time a solution the latching between the latching hook and the ceiling rail means. Due to the small idle stroke, caused by the recess inside the drive means connection in conjunction with the locking pin is Thus, before the movement of the garage door or the like, a solution of Latching between the latching hook and the ceiling rail lifted. In the subsequent closing transition will be in the closed position the garage door or the like automatically the latch hook again snap into a catch of the ceiling rail, so that a corresponding unintentional opening is omitted and thus a burglar alarm is present.

in the Case of a power failure is by means of a release lever, preferably in conjunction with a rope, also a repeal of Locking of the latching hook with the ceiling rail possible. For this is about the sear the locking pin from its locked position, d. H. from the recess the drive means connection pulled out and thus gives the drive means free. This means that now the garage door or the like be opened manually can. To connect between the coupling unit and the garage door It is necessary to restore the drive means connection again enters the clutch unit, and thus it to a Locking between the locking pin and the drive means connection comes.

at manual retraction the locking bolt is also the two-armed latch hook simultaneously actuated, allowing a lifting of the locking position of the latching hook inside the ceiling rail is done. Due to the direct or indirect connection of the Garage doors or the like over a lever or the like can now be moved manually.

With Help of the invention, it is also possible, the manual Verfahrung the garage door to make even if the locking position of the Locking pin is switched off permanently. In the permanent shutdown of the locking pin this is from the region of the recess of the Driven drive connection out and held in this position. At the same time, this means that even the latching hook is not inside active the ceiling rail can be. To cancel the permanent release of the locking pin, is for it on the latch hook a trigger, which activates the locking pin again so that it is in its rest position retracted within the recess of the drive means connection is.

The Invention is described below with reference to a schematic in the figures shown possible embodiment explained in more detail.

It shows:

1 : A perspective view of a coupling unit;

2 : A plan view of a coupling unit according to 1 ;

3 FIG. 4 is a sectional view along a section line BB of FIG 2 ;

4 a bottom view of the coupling unit according to 1 ;

5 FIG. 3 is a sectional view taken along a section AA of FIG 4 ,

In the 1 is a coupling unit 16 represented by a housing 1 This essentially consists of three chambers 7 . 8th . 9 is divided. While the chambers 7 and 9 for the implementation of a drive means 2 serve is in the chamber 8th between the chambers 7 and 9 There is a locking mechanism included. Below the case 1 is a connection 4 with a cut 34 for connection to a garage door or the like. Since this connection is not relevant to the invention, it is not shown in the figures. Furthermore, located at the bottom of the case 1 a Zugmittelführung 6 which serves to receive a rope or the like, one end of which is on a release lever 3 is attached. Through the release lever 3 , as will be described below, a manual unlatching of the coupling unit 16 be performed.

In the 2 becomes the driving means 2 visible from above, leaving one at the ends of the powered by 2 fixed drive means connection 12 becomes visible. About a connection 31 become the ends of the drive means 2 with the drive means connection 12 connected. The drive means connection 12 Its width is designed to be within the chamber 7 can be led with play.

Within the drive means connection 12 there is a recess 15 for a locking pin 13 who is in the chamber 8th is slidably mounted and by a spring 25 in a blocking position according to the 2 is pressed. Again 2 it can also be seen, the width of the locking pin 13 much smaller than the length of the recess 15 within the drive means connection 12 ,

On the drive means connection is also a driver 28 , the side run-up slopes 30 having. With the driver 28 and the run-up slopes 30 acts a starting bolt 17 together, the part of a two-armed latching hook 10 is. The latching hook 10 is about an axis 18 inside the chamber 8th stored. The latching hook 10 with the arms 20 and 21 serves with a run-on slope 11 and an undercut 14 for latching in the closed position of the garage door or the like with one in which at least one catch 37 located.

The arm 20 of the latching hook 10 has the starting bolt 17 and a trigger 29 on. This release lever 29 engages in a leadership 19 one that is stationary within the chamber 8th is formed. The latching hook 10 is about a spring 5 so spring loaded that it is always pressed into a latched position.

In a motorized operation of the drive means 2 this will be in the left direction according to the 2 moved that on the one hand the locking pin 13 inside the recess 15 slipped without actuation and at the same time the starting bolt 17 in the area of the run-up slope 30 comes and through the highest point of the driver 28 a pivoting of the latching hook 10 around his axis 18 he follows. This will unlock the latching hook 10 with his undercut 14 inside the guide rail 35 reached. After unlocking the coupling unit 16 has taken place, this can by the locking pin 13 within the drive means connection 12 with the recess 15 cause an opening of the connected garage door or the like in that the entire coupling unit 16 inside the ceiling track 35 is moved. To here a reduction of frictional forces within the ceiling rail 35 are to be reduced at the coupling unit 16 laterally projections 25 and at the top, projections 40 present, which only a point contact with the ceiling rail 35 guarantee.

From the 3 with the cut BB is the function of the starting pin 17 with the run-on slopes 30 clear.

Furthermore, the 2 and 3 the connection of the release lever 3 be removed for manual operation. In this case, the trigger lever 3 is within a pivot point 23 stored. While the release lever 3 at the bottom of the case 1 is the end of the fulcrum 23 inside the chamber 8th with a lever 24 provided with the locking pin 13 so cooperates that upon rotation of the trigger lever 3 (For example, by a manual release) of the locking pin 13 from the recess 15 the drive means connection 12 is pulled out. At the same time but also a pivoting of the latching hook 10 around the axis 18 causes, so that unlocking and thus decoupling of the coupling unit 16 from the ceiling rail 35 he follows.

The sectional view according to the 5 AA clearly shows the positioning of the latching hook 10 with the arms 20 and 21 , While the arm 21 with the undercut 14 inside the detent 37 the ceiling rail is engaged, is the arm 20 with the release lever 29 in the area of the locking bolt 13 to a projection 39 stored. To the projection 39 closes a run-on slope 36 on, in a withdrawal of the locking pin 13 from the locked position at the same time a gift of the latching hook 10 from the in the 5 shown detent causes.

Upon actuation of the release lever 3 can also by a certain position a permanent release of the latching hook 10 respectively. In such a case, the release lever 29 on a unlocking surface 26 of the locking bolt 13 pushed, so that the latching hook can not turn back into a rest position. To be able to cancel this permanent release, located on the arm 20 of the latching hook 10 a trigger 32 passing through a hole 38 inside the case 1 out of the case 1 looks out and thus by pressing the release lever 32 resets the permanent unlocking.

In the 4 becomes the coupling unit 16 shown by its bottom, in which also the trigger 32 is visible. About the connection 4 with the incision 34 and a hole 33 may be a connection, not shown, between the garage door or the like and the coupling unit 16 getting produced.

Inside an outer wall 27 according to the 1 is a breakthrough 41 shown. The through fracture 41 is located opposite the recess 15 the drive means connection 12 and thus exactly opposite to the placement of the locking pin 13 , Through this breakthrough 41 It is also possible to manually repress the locking pin 13 to effect.

To a simple shrinking after unlocking the locking pin 13 into the recess 15 to ensure, are at the drive means connection 12 chamfers 42 present when hitting the locking pin 13 this from its locked position against the spring 35 Press and after overcoming the starting slope 42 engages the locking pin 13 again in the recess 15 one.

The description of the present invention shows that by creating the coupling unit 16 an effective anti-burglary device has been created which allows to be manufactured inexpensively and requires little space. Furthermore, it makes a relatively complicated locking system with multiple levers dispensable.
