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 with an integrated auxiliary drive assigned to it with a push rod 5. 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 , the opposite end of the push rod 5 being connected to the relevant sliding door leaf 1 .

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 staggered 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 of, for example, 800 mm to 2300 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 .

The further construction of the push rod 5 mentioned will now be explained with reference to the following figures.

The push rod 5 consists in the embodiment shown, for example, a push rod base element 5 a and a movable to it by means of the integrated auxiliary power actuator push rod actuator 5 b, which can be extended telescopically in the embodiment shown by means of an auxiliary drive for the axial extension of the push rod 5 .

Referring to Figs. 3 and 4 is the working principle he explained.

On the push rod base element 5 a, a rubber-elastic cable is attached to cable fastening points 9 and deflected from these fastening points (near the end of the push rod base element 5 a) via deflecting rollers 11 at the other end of the push rod base element 5 and under formation a loop 13 in the hollow len cross-section of the push rod base element 5 a (on the further structural details of the push rod will be later on with reference to FIGS . 5ff gene). The rubber-elastic cable 15 is moved back parallel from the loop reversal 13 again, namely by a parallel to the first pulley 11 pulley 11 to the second cable attachment point 9th

The relatively movable pushrod actuator 5 b is more or less entirely inserted into the pushrod base element 5 a in normal operation, the loop 13 pressurizing the rear end of the inserted pushrod actuator 5 b. In this basic position, the system is excited, as it is shown in Fig. 3 Darge.

In abnormal operation, a corresponding locking mechanism is released, so that the push rod actuator in the sense of an axial extension of the entire push rod 5 is supported relative to the belt drive 3 by the tensile force of the rubber-elastic cable 15 via the loop engaging at the rear end of the push rod actuating element 5 b Push rod base element 5 a extends. Since can also in the basic position of the closed sliding door shown in Fig. 1 only by the effectiveness of the auxiliary drive thus formed in the abnormal case by the aforementioned axial extension of the push rod 5 overall, even with the belt drive 3 standing, the respective sliding door leaf in its in Fig Publ shown. 2 are shifted voltage position.

The following is the thrust on the further detailed structure bar received.

According to the following figures, the push rod 5 consists of a cross-sectionally U-shaped push rod element 5 a, which in the exemplary embodiment shown consists of two cross-sectionally L-shaped and symmetrical to one another and correspondingly composed shell parts 5 'and 5 ''( Figs. 10 to 15).

According to the illustration according to FIGS. 5 to 8 and 10 to 15 shows that the extension side of the principal thrust rod element 5 a forth (to which the Abnormbe drive the thrust rod setting element 5 b driven by the auxiliary is extended) which in the illustrated Execution game in cross section rectangular shaped push rod gene actuator 5 b under tension and entrainment of the rubber elastic loop 13 and under expansion of the rubber elastic cable 15 can be inserted into the push rod base element 5 a. In this case, 11 to 15, the thrust is according to the cross-sectional view of FIGS. Pole base member 5 designed a such that the rod type gene actuator 5 b by lateral guide surfaces 19 and is guided only axially displaceable downwardly facing guide surface 21.

In the lower area of the principal thrust rod element 5 a is formed laterally of the provided with the guide surfaces 19 guide lugs 27, a free space that is created by its dimension so that therein just the rubber-elastic cable 15 from the front guide rollers 11 coming inside the Push rod base element 5 a to the rear loop 13 can be moved, the rear loop 13 of the rubber-elastic cable 15, the rear end of the push rod actuating element 5 b always securely grips and thereby the push rod gene actuating element 5 b with the force of the rubber elastic Cable 15 pressurized.

In the half space located above the guide lugs 27 in the push rod base element 5 a, the two sections of the rubber-elastic cable pull 15 are guided from the deflection pulleys 11 lying in the direction of extension to the rear cable attachment points 9 mentioned ( FIGS. 8 and 9). In Figs. 5 to 9 and Fig. 11 in cross-section rope fixing means 9 and 29 suitable for both ends of the elastic rope hoist 15th The rope ends can be firmly clamped by means of two screws 31 with a fixed clamping plate 33 . The clamping plate 33 is part of a rope monitoring device to be explained below.

The bracing is not fixed to the Grundele element 5 a, but fixed to a relative to the push rod base element 5 a at its rear end over a certain axial path relatively adjustable and the Spannplat te 33 comprehensive trigger slide 35 , the meaning of which will be discussed later becomes.

Referring to Figs. 16 to 19 as the auxiliary drive is placed in its clamped position under tension of the elastomeric pull cable 15 will be explained. For tensioning the relatively movable push rod 5 b, the axially movable push rod actuating element 5 b is inserted from the front end insertion opening in the region of the deflecting rollers 11 , taking the rubber-elastic loop 13 into the push rod basic element 5 a. In the rear loading area of the push rod is - as can be seen in particular from FIGS. 16 to 19 - a freely rotatable locking roller 37 rotatable about a horizontal and transverse to the longitudinal direction of the push rod in a cage. The cage 39 for the locking roller 37 to a cross slot 41 in a rear region 43 of the push rod base element 5 a.

The diameter of the locking roller 37 is larger than the thickness of the rear region 43 of the push rod base element 5 a. On the opposite end faces of the locking roller 37 there are pins 45 , over which the locking roller 37 sits non-slip ( FIG. 15).

In the inserted position - if the push rod actuating element 5 b is inserted into the push rod base element 5 a - there is a slide plate 47 a covering the transverse slot 41 in the basic position in the position shown in FIG. 16, in which one in the Slide plate 47 a introduced further passage slot 49 comes to lie in plan view above the transverse slot 41 introduced in the rear region 43 of the push rod base element 5 a.

When inserting the push rod actuating element 5 b - if the locking roller 37 reaches before the current end of the push rod - this is raised to the position shown in FIG. 16, in which the roller is formed in the cavity formed by the passage slot 49 and the transverse slot 41 comes to rest. From the illustration it is evident that the total height of the transverse slot 41 and the passage slot 49 speaks to the diameter of the roller 37 or is slightly larger.

When the push rod actuator 5 b is inserted further, the locking roller 37 then falls with a part diameter range into a recess 51 formed on the top of the push rod actuator 5 b, the height of which approximately corresponds to the thickness of the slide plate 47 a. The locking recess 51 is designed in the form of a cutout, which is seen in the direction of thrust leading and trailing with a bevel, ie with a rising flank deviating from a step heel.

So that the roller-shaped locking body 37 is held in the aforementioned cage even when the push rod actuator 5 b is extended, it is provided that the axial length of the locking roller 37 is greater than the width of the push rod actuator 5 b and thus larger than that by the two opposite sliding surfaces 19 formed clearance in the push rod base element 5 a. It is also below the Verriege treatment roller 37 in the opposite wall sections 5 ', 5 ''of the push rod base element 5 a, a recess 52 resulting recess, which corresponds approximately to the depth of the cutout 51 in the push rod actuating element 5 b . When the push rod actuating element 5 b is extended, the locking roller 37 rests with its jacket sections adjacent to its end faces on the mentioned cutouts 52 . These cutouts 52 are visible in the cross-sectional view according to FIG. 15.

With further pushing of the push rod actuator 5 b, the slide 47 and thus the slide plate 47 a is now provided with its end face, perpendicular to the pre-aligned armature plate 53 until it abuts against an electrical holding magnet 55 . For this purpose, a driver pin 57 is provided, the plate 47 sits on the slide and protrudes down to the level of the Schubstan gene-control element 5 b ( Fig. 18). It can also be seen from the structure explained that the slide 47 , as shown in the drawing, sits at the end of the push rod base element 5 a and is anchored such that it only adjusts the rod base element 5 a by an axial path relative to the push rod can be.

In this position shown in Fig. 19, the Haftma gnet 55 holds the anchor plate 53 with the slide 47 in the locked position.

After releasing the push rod adjusting element 5 b, however, this is again pushed away from the holding magnet 55 by the rubber-elastic cable 15 mentioned, but only up to the locking position shown in FIG. 19. After coming through the previously effected displacement and entrainment of the slide 47 in the slide plate 47 a front seen through slot 49 offset from the transverse slot 41 in the cover plate to be 43, so that now the slide plate 47 a the transverse slot 41 in the on the push rod Base element 5 a firmly and immovably anchored cover plate covered at the top and holds closed, so that the locking roller 37 can not be pushed upwards out of the locking recess 51 formed in the form of a cutout in the push rod actuator 5 b.

From the adjustment mechanism described above, the length of the locking recess 51 is such that a before pushing and driving movement of the slide 47 from the position shown in FIGS . 16 and 17 (unlocking position) to the one in FIGS . 18 and 19 ge shown locking position is enabled.

If the current were to fail in an abnormal operation, the holding magnet 55 would be switched off immediately, via which the slide 47 and thus the slide plate 47 a from its position in FIG. 19 to the position shown in FIGS. 16 and 17 due to the position shown in FIGS. 6 to 8 shown slide tension springs 59 are withdrawn, with the result that in this, as in the entry position shown in FIGS . 16 and 17, now the push rod actuating element 5 b by the force of the rubber-elastic cable 15 while pushing out the Locking roller 37 immediately extends from the locking recess 51 .

From the structure described it can be seen that the locking of the extendable push rod actuating element 5 b takes place mechanically, namely by means of a locking body 37 in the embodiment shown in the form of a locking roller 37 , the triggering and release of this mechanical locking being carried out by means of a magnetic actuating device. As a result, only small forces have to be applied by the holding magnet, namely to hold the slide 47 against the force of the slide tension spring 59 in the locking position. The actual tensile forces of the auxiliary drive initiated by the rubber-elastic cable 15 on the movable push rod adjusting element 5 b are taken up and supported by the mechanical locking device.

As can also be seen from FIGS . 6 to 9, the exemplary embodiment also includes a rope monitoring device 61 . Not only in the event of a crack in the rubber-elastic cable 15 , but also when the pretensioning force falls below a presettable value, the sliding door will automatically be moved to the open position even when the belt drive is not moving.

In Figs. 6 and 7 is also a turn inserted and shown in the tensioned state pushrod Stellelemen tes 5 b in the locked position shown in the end of the thrust rod element 5.

For this purpose, a rope monitoring switch 63 is also attached to the tensioning plate 33 already mentioned above and belonging to the rope monitoring device 61 . This rope monitoring switch 63 is switched into its actuated position by a pin 33 a projecting upwards in the push rod base element 5 a, in which the electrical holding magnet 55 is supplied with voltage via an electrical line leading via the monitoring switch 63 and not shown in detail. In this position shown in FIGS. 6 and 7, the locking roller 37 is just in case again in engagement with the movable push rod gene control element 5 b and thus locked.

The two tension springs 59 which place the slide 47 under tension have a double function in this respect. On the one hand, they not only serve to switch the slide in the event of a drop in the holding magnet (i.e. in the event of a power failure), but they also serve to monitor the rope by counteracting the rubber force. This is because the rope monitoring device 61 , which is designed in the manner of a further slide and is displaceable on the push rod base element 5 a only longitudinally by a certain axial path and is formed in the manner of a release slide, is not supported by separate tension springs, but rather by means of the already mentioned tension springs 59 , which is what Slider 47 and the rope monitoring device 61 formed in the manner of a slider are kept biased towards one another.

If the cable tension now subsides, the aforementioned release slide 35 with the clamping plate 33 is pulled back by the tension springs 59 (in the direction of the holding magnet 55 ), so that the circuit closed via the cable monitoring switch 63 with the electrical holding magnet is interrupted ( FIGS. 8 and 9). As a result, the holding magnet falls off. As a result, the slide 47 is now pulled back from the holding magnet by the same tension springs 59 mentioned above, as a result of which the mechanical locking of the push rod adjusting element 5 b is released. Because now the locking roller 37 can be freely raised upwards into the soft and release slot 49 , whereby the movable, extendable part of the push rod, namely the push rod actuator 5 b extended and above it the sliding door leaf 1 is moved to the open position.
