Description

The invention relates to an automatic wing or door System according to the preamble of claim 1.

There are a wide variety of automatic door systems known, in particular automatic sliding door systems, automatic swing systems, revolving doors with rotie wings etc.

The doors open automatically in automatic mode and closed. With a revolving door, this can mean that the revolving door is operated in the forward direction, when a person approaches the revolving door.

Such doors should open after business or office hours be locked. This can be done mechanically, for example (by hand) or by a separate electrical Control device take place. So should z. B. the Ver Locking is not carried out manually, a corresponding must  Control device may be provided for this. This is in usually a lock is provided in the drives, which, for example, on the carriages, the door panels wear, work. This lock is on the drive control operated and monitored.

The object of the present invention is for such Automatically operated wing or door systems, in particular other sliding door systems with at least one sliding door wing, a simplification for triggering a wide Ren actuator, especially a lock provision device.

The task is according to the invention in accordance with solved claim 1 specified features. Advantageous Ausge Events of the invention are set out in the dependent claims give.

The invention can be particularly advantageous in particular use for automatic locking of a door system, although basically with the principle according to the invention also other additional control devices can be controlled or triggered without the invention a separate drive or control device is not necessary is agile.

According to the invention it is provided that in the the operating position (in the case of a sliding door system at for example when the closed position is reached) the mecha African locking can be carried out automatically  can that the drive and / or transmission means for Adjustment of the door in the closed position after reaching the final closed position over a certain distance or swivel position can be adjusted to within the scope of this additional adjustment path the additional che actuator, for example the locks to activate, switch, etc.

In a preferred embodiment of the invention in addition, in the case of a sliding door system, the Proposed transmission means in the direction of thrust (Opening direction) in direct operative connection as stand an undivided drive device, and the in Closing direction (e.g. pull direction) due to the Bipartite a separation of the power transmission means provide for the additional adjustment movement Allow to trigger the actuator.

A two-part, telescopic push rod is basically already known from DE 195 49 006 A1 become. There is the two-part telescopic Push rod together with a rubber band-like auxiliary used to drive the Door still in due to the integrated energy storage To bring closed position. The preferred branches shared push rods is used according to the present invention but different from this state of the art task. There is also a telescopic extension the two-part push rod according to the present An message only against the force of a spring device  possible.

Preference is given to the two-part at the point of separation Push rod according to the present invention an "expan the device "provided, which enables the Drive and / or transmission means for the adjustment movement for example the door leaf when it reaches Closed position over a certain distance can be moved to only after reaching the The locking device is in the closed position of the door leaf to operate. Instead of or in addition to one "Expanders" can also be used for other doors tion or a coupling of the two relative to each other movable parts can be provided, for example a mechanical locking and coupling connection, an electromagnetic table-controlled or only electrically controlled coupling and release device or one by means of permanent magnets working device and / or a mechanical coupling device, and the one when tractive forces are exceeded Separation allowed to join the two parts Exceeding pressure forces and / or when touched firmly connects these two parts together.

It has proven beneficial if the additional Actuating device, for example the aforementioned Ver locking device, such a locking mechanism has that after triggering the actuator and backward movement of the drive and transmission with tel in their basic position, which they Usually take the closed position of the door in the  Hold the desired triggered or locked position. This can be done, for example, by means of a ratchet lever mechanism mus or by another locking device. The actuator is thereby permanently in the Operating position held so that, for example Door is permanently locked by manual release of the Actuator or by actuation by means of a electrical holding magnet.

Because under certain circumstances this is about the drive and / or over Actuator triggered in the suspension means not immediately direct spatial allocation to the locking device device or any other device that can be triggered via it device is arranged, a corresponding over Carrier device may be provided. This can be done in one preferred embodiment of the invention from a Pressure line, for example an oil pressure line, best hen, the pressure from a trigger cylinder to one Locking mechanism transmits.

An embodiment of the invention is as follows explained in more detail with reference to drawings. Show in single:

Fig. 7: an enlarged detail view of the actuating and locking device.

In Figs. 1 and 2 in a schematic representation excerpts a sliding door is shown with two sliding door leaves 1, in Fig. 1 in the closed and in Fig. 2 in the open position.

About a revolving belt drive 3 , the doors between their closed and their open position will move ver, the sliding door 1 are usually supported by means of two staggered in the longitudinal direction of the carriage on a longitudinally running in the belt drive 3 rail.

As is apparent from the illustration according to FIGS. 1 and 2, each sliding door leaf 1 is connected to a push rod 5 associated therewith. In other words, here the push rod 5 is fastened at one end to the corresponding upper or lower run of the belt drive 3 at a fastening point 13 , the opposite end of the push rod 5 being connected to the relevant sliding door leaf 1 , generally via the first of several carriages that carry the door leaf and over which the leaf can be moved along a rail, not shown in detail.

Due to the offset support of this push rod 5 with its one end on the belt drive 3 and offset at its other end on the associated sliding door leaf 1 it gives the possibility that with constant dimen sionation and the same distance between the two deflection rollers shown in FIGS . 1 and 2 7 for the belt drive 3 by offset selection of the support points of the push rods 5 on the belt drive 3 and / or on the respective sliding door leaf 1 different opening widths for the door from, for example, 800 mm to 2800 mm can be realized, since the sliding door leaf 1 even over the outside Deflection rollers 7 can also be moved into the open position by using the push rod 5 .

As can be seen from the more detailed illustration according to FIG. 3, the deflection roller 7 on the left in the excerpt shown in detail is driven for the belt drive 3 via an electric drive 11 (electric motor), the control of the electric motor in the usual manner according to the operation an automatic sliding door system.

The drive for the right door leaf 1 'provided on the left and connected to the upper run of the belt belt 3 in connection push rod 5 ' is firmly connected to the belt belt at 13 , whereas the right-hand end of this push rod 5 'over the left door wing leads to the first carriage 15 , which is provided in the door leaf 1 arranged on the right in FIG. 3 at the top left. However, in Fig. 3, this push rod 5 'is not drawn through, but omitted in the area adjacent to the vertical to the plane of the door plane, to which the two door leaves are in their closed position Ver, omitted. The same applies to the connecting rod 5 '' in FIG. 3 with the lower strand of the belt 3 . There, too, the push rod, which leads to the nearest barrel 15 of the left door leaf and is connected to it there, is not drawn continuously in the area of the parting plane between the two door leaves 1 , in order to better show the construction behind it.

The two push rods 5 are in the embodiment shown, for example, divided into two and each have a first and a second rod part 5 a, 5 b, which are provided with an integrated expander device 17 . The structure of the push rods 5 a and 5 b is such that the two push rods are connected to each other by the pander device so that they are connected in the push direction without change in length. That is, in the direction of thrust initiated to carry out an opening movement of the sliding door leaf is with corresponding drive connection from the electric motor via the belt drive 3 and the push rods 5, the two sliding door leaf 1 immediately carried along and adjusted to the opening position.

With reverse control for reversing the open sliding door leaf 1 in the closed position, the tensile or expander forces of the expander device 17 are set so that the two push rods parts 5a and 5b are also firmly against one another when the tensile forces are initiated and the integrated spring or expander device 17 is not stretched becomes. The two push rod parts 5 a and 5 b are thus held against one another in a limit-limited manner via an expander device. The two thrust rod parts 5 a and 5 b mutually biasing forces are greater than the forces introduced when performing a closing movement via the drive device, so that even with tensile stress and adjustment movement of the respective drive device 11 closer push rod part 5 a of it over the Ex pandereinrichtung connected push rod part 5 b a finally the movable door leaf is also directly adjusted without the expander device being stretched or substantially stretched. The two thrust rod parts 5 a and 5 b are preferably telescopically inserted in order to ensure optimal guidance.

As soon as the sliding door wings have received their closed position shown in Fig. 1 or 3 ge, the expander devices 17 allow, however, that the Antriebseinrich device can run to a certain extent further in the closed position, with the result that the over the attachment points 13 with the belt drive 3 connected thrust gene parts 5 a despite the fact that the sliding door leaf is already in the closed position (which therefore cannot be adjusted further to its closed position) can still be moved to a certain extent.

The end 21 of the push rod 5 'located on the left in FIG. 3 and opposite the reversible door leaf 1 is designed as a stop or driving end.

In the following, reference is also made additionally to FIG. 4, in which the further structure differs in detail. The situation is shown in Fig. 4 at the time, in which via the drive device, the two sliding wing 1 its closed position it have sufficient lie in so the successive pointing closing edges of the two wings 1 each other. As mentioned, starting from this starting position, the push rod parts 5 a, each connected to the belt drive 3 , can also be adjusted over a certain distance in the closing direction, that is, an additional adjustment can be made by a movement path 23 , from the position shown in FIG. 4 extends to the position shown in FIG. 5.

This after reaching the closed position of the door leaf only from the push rod end 21 continuous movement path 23 can for example have a length of 1 to 5 cm, for example by 3 cm.

The stop or driver end 21 or a correspondingly provided and co-operating with the belt drive 3 stop or driver device 21 cooperates with a trigger device 25 , which in the exemplary embodiment shown consists of a hydraulic cylinder 25 '. This hydraulic cylinder is now pressed from the position shown in FIG. 4 (unactuated state) into the trigger position shown in FIG. 5.

The trigger device 25 or the hydraulic cylinder 25 'is provided with a locking element 27 in the form of a pressure plate 27 ' which during the push-in movement through the push rod end runs onto a wedge-shaped contact surface 29 of a hook 31 , this from its locking position according to FIG. 4 moved downwards, the hook after overflowing the casserole surface 29 is moved back into its starting position shown in Fig. 4, for example by a compression spring device not shown in the drawing. In this situation, the pressed-in hydraulic cylinder 27 'is now held in its pressed-in form, since the locking element 27 cannot be moved to the right beyond the hook. In this position, the drive and transmission device can then be pivoted back into their starting position (i.e. immediately after corresponding actuation, that is to say pressing in of the hydraulic cylinder 27 '), that is to say the drive motor and the belt drive 3 , until they reach that position which corresponds to the closed position the door leaf 1 correspond. In this situation there is then a distance between the stop surface 21 at the end of the push rod 5 and the plat ten-shaped locking element 27 , 27 '.

From Fig. 4 it can also be seen in particular that the hook 31 is attached to a lever 33 which can be adjusted about a pivot axis 35 . The spring device mentioned for the return movement of the hook 29 in a position securing the pressure plate against pivoting back position can be accommodated in a holding magnet 75, which will be discussed below.

From the release device 25 designed in the form of a hydraulic cylinder 25 ', a transmission device 37 in the exemplary embodiment shown is in the form of a hydraulic line 37 ', which leads to an actual actuating device 39 in the exemplary embodiment shown in the form of a locking device 39 'which extends above the central parting plane 41 between the two door panels is seen before.

In order to lock the doors in the shown embodiment very firmly and securely, is adjacent to the two in the closed position, so successive sides facing vertical end profiles or termination end 43 two almost the entire height of the door pass through the locking rods 45 are provided, shown in Figs . are given tail 6a to 6d in the different phases during the locking and the opening operation in the larger De. In Fig. 7, to the hereinafter also referred to, which is Betätigungsein direction 39 in the form of a hydraulic cylinder 39 'is increased by comprehensive locking means 39 shown.

By the mentioned actuation of the triggering device 25, ie through the Eidrücken of the hydraulic cylinder 25 ', hydraulic pressure medium is supplied to the locking means through the likleitung in the form of a Hydrau 37 formed transfer device 37 39' transferred forming the hydraulic cylinder 39 '', which from its in Figure 7 ge. exhibited opening or unlocking position is moved into its contrast lowered locking position.

The hydraulic cylinder 39 '' has a lower acquisition or pressure plate 51 , which comes to lie in the open position shown in Fig. 7 above the top 53 of the door leaf 1 at a distance from the underlying profiles 43 from. In this position, actuating ends 55 of the locking rods 45 protrude above the upper side 53 of the door leaf. With exclusion, ie pressing the hydraulic cylinder 25 , a pressure medium is pressed into the hydraulic cylinder 39 '' via the oil pressure line 37 ', which then extends downwards, and then via its lower pressure plate 51 , the protruding actuating ends 55 shown in FIG. 7 Lock bar 45 moves downwards.

The actuating end 55 of the locking bar 45 protruding above is pressed completely into the end profiles 43 .

In Fig. 6a, the respective locking bar 45 provided in the end profile 43 is shown in a schematic excerpted longitudinal section through the profile end of a door leaf.

It is divided into several parts and includes a plurality of locking bar parts 45 a to 45 c sitting one behind the other in the axial direction, some of which are guided by stationary guides 57 , and which partially include movable guide elements 63 movable with the bars. Furthermore, the separation points 64 a and 64 b are drawn in, which mark the separation points of the three locking bar parts in the starting position according to FIG. 5a.

The larger in the upper frame diameter spring, ie larger spring force storage device 59 holds the locking rod 45 a to 45 c in the shown in Fig. 6a REN, ie upper position, in which there is an unlocking. This position is therefore in normal door opening and closing operation.

The smaller-diameter spring means 59 a, which is disposed within the one larger diameter helical spring device 59 is required to compress the locking bar, if not yet, that is in an associated bottom receiving a zugehöri ges bottom hole 65 is penetrated to the final locking to effect.

The shown in the illustrations shown in the lower part of the door leaf further spring force storage package, ie the associated spring device 61 is used to return and hold up the bolt linkage part in the door leaf in the usual operating mode in which an unlocking is present.

Figs. 6b and 6c show the tie-rod upon a failure test in which no hit, that is, the projecting bottom end of locking bar 65 is penetrated not causing in the associated, the locking hole 67 bottom. The bolt linkage in the upper spring area is compressed and a rod or release part 70 tapering at the upper actuation end 68 tapering at the upper end of the door leaf still protrudes upwards, and thereby engages through a correspondingly dimensioned opening in FIG Pressure plate 51 upwards, where in Fig. 7 further not shown microswitches are arranged. In other words, in such a failed attempt according to FIGS. 6b to 6c, the trigger pin 70 and the actuated over it, not shown, microswitch of the electronics report that there is still no final locking. This allows the closing process to be repeated.

If the above, the locking effect, Lende loin 65 actually dips into the bottom opening 67 , this leads to a total displacement of the Riegelstan gene parts 45 a to 45 c, which then also the above in Fig. 6c protruding part 70 is retracted and the mentioned microswitch no longer triggered who.

In order to ensure a corresponding secure locking also at the upper end for the doors, the upper end strips from the doors or the vertical end profile strip 43 are each provided with a further locking bolt 71 which protrudes upwards to a certain degree ( FIG. 7) which then penetrates into the locking position accordingly concentrically seated holes in the pressure plate 51 , and thereby locks and secures the upper ends of the two doors against opening movement.

If a reversal is now to be made in the open position, the hook 31 is pivoted from its locking position into the open position, preferably via a holding magnet 75 shown in FIG. 4 and connected with a hook, which is therefore briefly reversed into the open position. This is done by an additionally provided spring energy storage device, for example in the form of a return spring, which is preferably integrated in the cylinder 25 . In other words, the spring system 25 a, when released by the hook 31, moves the system back into its starting position.

Characterized the hydraulic system with the return spring 25 a in the cylinder 25 in the starting position, so that now the upper and lower pressure spring accumulator 59 and 61 come into play and are each supported on two fixed guides, whereby the pressure spring force the movable guide located above it 63 or the actuating end 55 is pressurized in the opposite direction to the locking direction and thus the locking rod is moved into the open position according to FIG. 6a.

In the event of a power failure or a defect, the entire system can be locked or unlocked using a rod or, for example, a Bowden cable. Such a manually operable locking rod 77 is shown in Fig. 4 in the locked position and in Fig. 5 in the unlocked position (ie pulled out).

Finally, the position determination, whether z. B. there is a lock or unlock, also by means of a microswitch on the pressure plate 27 or monitored. Finally, a spring mechanism in each wing can also be used to monitor whether the locking bars have really penetrated completely into the floor in the floor recess assigned to it.
