According to the invention, a device for limiting the pivoting angle of the sliding leaf is present.

The device for limiting the pivoting angle of the sliding leaf may have at least one flexible force transmission element. This may for example be designed as a wire rope and thus, although suitable for the transmission of high forces, requires very little space.

The device for limiting the pivoting angle of the sliding leaf may further comprise at least one weight element. This ensures in a simple way that the flexible power transmission element is always subjected to train and thus does not sag.

The device for limiting the pivoting angle of the sliding leaf may further comprise at least one damping element. This ensures a smooth achievement of the maximum tilt angle of the sash.

The flexible power transmission element and / or the weight element and / or the damping element may be guided at least in sections within an interior of a profile element of the sliding leaf, so that the means for limiting the pivot angle during normal operation of the sliding door system is almost invisible.

On the support profile may be provided for attachment of the one end of the flexible power transmission element, a pivot point. The weight element may be attached to the other end of the flexible power transmission element.

The damping element may be attached to the weight element and cooperate with a wing-fixed component, such as an insert. Also a reverse arrangement is conceivable, i. in that the damping element can be fastened to a wing-fixed component, for example an insert, and can cooperate with the weight element.

The articulation point and / or the weight element and / or the damping element may comprise at least one adjusting device, through which the device for limiting the pivot angle in a simple manner to the local conditions, for example, the maximum tilt angle of the sash, can adjust.

The components of the device for limiting the pivot angle are simple parts of the contour and thus inexpensive to produce and also easy to install.

The sliding door system can be designed as an automatic sliding door system in that the sliding leaf can be driven by a drive device. Alternatively, it is also conceivable to use the article according to the invention in a sliding door system with manually operable sliding sashes.

In the Fig. 1a to 1c is designed as an automatic sliding door system sliding door system 1 shown in three different operating states. In the concrete embodiment, the sliding door system 1 has two opposite directions by a common drive device 6 driven sliding sash 2, which are guided on top of a stationary guide device, for example by means of roller carriage 8 on a guide rail 7, which together with the drive means 6 on a stationary frame structure 5, for example on a frame part of a mullion transom Construction is arranged above the passage area of the sliding door system 1. In addition to the sliding sashes 2, two side wings 3 are arranged, which extend in a plane closely adjacent to the sliding sashes 2. The side wings 3 are not moved during normal operation of the sliding door system 1. Above the drive means 6, a plurality of skylights 4 are present in the illustrated sliding door system 1.

In the operating state according to Fig. 1a which corresponds to the normal operation of the sliding door system 1, the sliding leaves 2 are automatically driven by the drive means 6 between their closed and their open position (direction of movement arrow A), for example by sensory or manual control of the drive means 6. In the drawing are the sliding sash second especially in partially open position during an opening or closing movement.

On the other hand lies in the in Fig. 1b A person who then would like to pass the sliding door system 1 in the direction of escape, ie from an endangered building section, the sliding panel 2 by substantially perpendicular to the sliding door system. 1 to bring in introduced, manual application of force from its closed position and thus open an escape route through the sliding door system 1 therethrough. For this purpose, the sliding leaves 2 have, in the region of their secondary closing edges, pivot bearings which allow pivoting about the pivot axes 10 (direction of movement arrow B). The upper pivot bearing is arranged in the region of a support profile 9, which is suspended on the two roller carriage 8, while the lower pivot bearing can be arranged in the region of a bottom guide element, not shown here. To the sliding sash 2 in Normal operation to fix in their oriented substantially in the plane of the sliding door system 1 basic position, locking devices are present, which may have, for example latching and / or permanent magnet elements whose holding force must be overcome by the manual application of force. The locking devices can be arranged, for example, in each case between the support profile 9 and the sliding leaf 2.

If an escape route is needed, which is wider than the passage width of the two sliding sash 2, which may be required in particular for a large number of people who want to pass the sliding door system 1 at the same time, it is provided, the two side wings 3 also out of its basic position swing out about pivot axes 11 in the direction of escape, including the side wings also have pivot bearing and locking devices. Furthermore, it is possible to push the already pivoted sliding sash 2 manually aside, as it is in the Fig. 1c (Direction of movement arrow C) is shown.

Of course, the pivoting of the sliding sash 2 and preferably also the side wing 3 can also be carried out when there is no emergency situation, but an object is to be brought through the sliding door system 1, whose width is greater than the opening width of the sliding sash.

In Fig. 2 is the left sliding sash 2 of the sliding door system 1 according to Fig. 1 shown in basic position in an oblique view from behind. The sliding leaf 2, which has a nebenschließungskantenseitigem vertical profile element 12, an upper horizontal profile element 13, a hauptschließkantenseitigem vertical profile element 14 and a lower horizontal profile element 15, is located with its surface extension below the support section 9 and is opposite this by means of a manual überdrückbaren, not here fixed locking device shown.

The sectional view according to Fig. 3 shows the upper Hauptschließkantenseitigen area of the sash 2 Fig. 2 , The trained as a hollow profile support profile 9 has an inner space 16, within which a fastening element 17 for a fixed articulation point 18 is fastened to an inner profile web. The bolt-like articulation point 18 protrudes downwards out of the support profile 9 and serves for fastening the end of a flexible force transmission element 19, which is designed as a wire rope in this embodiment, but in other embodiments may also be designed as a chain, belt or the like.

The main closing edge side, vertical profile element 14 of the sliding leaf 2 is also formed as a hollow profile and has an inner space 20, the upper opening is closed by an insert 21. The insert 21 is penetrated by a bore which opens at the top into a funnel-shaped insertion opening 22, through which the flexible force transmission element 19 is guided into the interior 20 of the profile element 14. In the illustrated basic position of the sliding leaf 2, the insertion opening 22 is located directly below the support profile 9 in the immediate vicinity of the articulation point 18 for the flexible power transmission element 19th

At the lower end of the flexible power transmission element 19, a weight member 24 is fixed and for this purpose has at least one mounting portion 25, which may be formed as a bore into which a screw can be screwed, which clamps the force transmission element 19 with the weight element 24.

At its upper side facing the insert 21, the weight element 24 has a receiving region 26 for a damping element 27. The receiving region 26 is formed in this embodiment as a blind bore, on the basis of which the end face of the damping element 27 designed as a helical spring is supported and some of the turns of the damping element 27 are enclosed by the receiving region 26. The fact that the inner diameter of the receiving region 26 corresponds to the outer diameter of the damping element 27, this is thus fixed by clamping in the weight member 24. The upper, free end of the damping element 27, which with its windings encloses the flexible power transmission element 19 and thereby is guided laterally, extends to the insert piece 21. Notwithstanding the helical spring shown, the damping element 27 may alternatively be formed as an elastically deformable solid or as a hydraulic damper.

The attachment position of the weight member 24 on the flexible power transmission element 19 is selected so that when located in the home position sliding sash 2, the distance L ₁ between the lower edge of the insert 21 and the free end of the damping element 27 is the same size as the distance L ₂ between the articulation point 18th and the insertion opening 22 at fully swung out sliding sash 2 (see Fig. 4 ). The flexible power transmission element 19 and the damping element 27 are components of a device for limiting the pivoting angle of the sliding leaf 2, whose operation will be described below.

The Fig. 4 shows the sliding sash 2 of Fig. 2 and 3 now in fully swung out position, ie the sliding sash 2 was, as it was already in Fig. 1b was shown, swung in the direction of escape (direction of movement arrow B). The located above the main closing edge of the sash 2 insertion opening 22 is thus no longer below the support section 9, but with the distance L ₂ of the articulation point 18 away, so that the flexible power transmission element 19 by a distance L ₂ corresponding length from the vertical Profile element 14 of the sash 2 was pulled out. Since the flexible power transmission element 19 is freely pivotally mounted on the articulation point 18, it has rotated in the appropriate direction, as in particular in perspective Fig. 5 is recognizable.

Since the flexible power transmission element 19 has been pulled out of the vertical profile element 14 of the sliding leaf 2 by a distance corresponding to the distance L ₂ , the weight element 24 has been extended by a corresponding length (L ₁ in FIG Fig. 3 ) in the interior 20 of the vertical profile element 14 of the sliding leaf 2 pulled upwards, so that the damping element 27 has come with its upper, free end edge in contact with the insert 21, as it is in Fig. 6 is shown. A further pivoting of the sliding leaf 2 now leads to a compression of the damping element 27 and thus to a damping of the pivoting movement of the sliding leaf 2 to a standstill, without resulting in a direct contact of the weight member 24 with the insert 21.

In an alternative, not shown embodiment of the object according to the invention, it is conceivable to arrange the damping element 27 on the insert 21, in which case the free end of the damping element 27 to the weight element 24 and in befindlichem in fully swung-out sliding sash 2 with the weight element 24 in contact comes.

In the illustrated embodiment, the mass of the weight member 24 is dimensioned so that it pulls the pivoting of the sliding sash 2 in its normal position, the flexible power transmission element 19 securely into the vertical profile element 14 of the sash 2 into it. In an alternative embodiment, the weight member 24 may be formed to a greater mass, so that it acts on the swung-sliding panel 2 in the direction of its basic position, i. that it acts like a so-called door closer. This may be advantageous, for example, if the sliding door system 1 should serve both as an escape route and as smoke protection. Alternatively or additionally, for this purpose, a return element, for example, elastic can be arranged below the weight element 24.

In a further alternative, not shown embodiment of the subject invention, it is conceivable to guide the flexible power transmission element 19 within the vertical profile element 14 of the sliding leaf 2 via one or more deflection elements, eg pulleys in the manner of a "pulley", whereby the impact velocity of Damping element 27 is reduced to the insert or on the weight element 24.
