The locking takes place from a control of the sliding door automatically.

All of the previously mentioned embodiments have in common that the latches tion device is operated via a separate drive unit, which can be controlled via the door control.

DE-OS 44 28 718 describes a device for forced actuation a locking device for all-glass elements, which mechanically at Pushing together the all-glass elements is triggered and this against the Locked bottom. To do this, there is one at one end of the lower metal frame All-glass element attached a wedge-shaped casserole. On the opposite The end of the metal frame is a two-armed actuation lever for the locking device device pivotally supported, on the one pointing into the metal frame Arm acts a spring, which keeps the vertical locking bolt in contact is. The other arm protruding over the metal frame runs when it is pushed together push up two all-glass elements on the wedge-shaped casserole part moves the locking bolt with the other lever arm in a bottom-side shell, which means that the first all-glass element second second all-glass element is locked.

However, this embodiment is unsuitable for single-leaf sliding doors, because the Locking device of the all-glass element to be locked by a second accumulating all-glass element must be operated. It is also required This means that the element to be locked is previously at rest over the receiving sleeve position.

The object of the invention is to develop a locking device that used for single-leaf as well as double-leaf sliding door systems can be and which is optically inconspicuous in the sliding door or Can integrate sliding door fitting. Preferred versions are intended to be independent work from an electric locking drive.

The object is achieved in that at least in part area of the distance that the wing at an opening and / or Closing process covers the bolt movement when unlocking and / or Locking process, using the movement of the bolt carrying Wing is carried out, preferably mechanically coupled to the wing movement.

Depending on the wing movement and / or wing position This controllable bolt is in the wing or in a fitting of the wing Men, wherein it is preferably arranged near the main closing edge. Of the Latch lies horizontally or vertically in the wing plane and secures it in its ver locking position the wing against pressing perpendicular to the locking level.

FIG. 7 shows an alternative embodiment of the locking device in Figure 1, wherein the locking unit in the vertical fitting of the blade is housed, and a transmission is connected between the latch bolt and a firing pin.

Fig. 1 shows the schematic front view of an automatic sliding door system ge 1 with two sliding door leaves 1 a and 1 b, which are driven in opposite directions by a motor. The sliding door leaves 1 a, 1 b are slidably guided over a pair of roller carriages 42 in a horizontal stationary track 41 . The Laufschie ne 41 is part of the support member 4 , which is also arranged stationary above the door opening for taking on the individual components or modules of the sliding door system 1 .

The drive has an electric motor 3 , which is connected to an electronic control device 2 . The motor 3 drives via a gear, not shown, and a first deflection roller 31 a to a toothed belt 32 , which is guided circumferentially via a second free-running deflection roller 31 b.

The sliding door leaves 1 a, 1 b are coupled to the toothed belt via drivers 33 a, 33 b. For this purpose, the lower run 32 a of the toothed belt 32 is connected via a slave 33 a with the sliding sash 1 a and the upper run 32 b via a driver 33 b with the sliding sash 1 b, so that the wing 1 a, 1 b only can move in opposite directions.

The motor 3 is controlled via a control and regulating device 2 , which is arranged, for example, in the carrier element 4 . To the signal of a sensor, not shown, or an external switch, the sliding panels 1 are when a person approaches a, 1 b automatically opened and closed again below about the engine. 3

In the lower horizontal fitting 13 of the sliding sash 1 a, 1 b, a locking device 5 is arranged, which secures the wing 1 a, 1 b against pressing open perpendicular to the wing plane. Here, the one wing 1 a has a bolt 51 which engages in the locking state in a bolt receptacle 5 b of the opposite wing 1 b. The arrangement of the locking device 5 can alternatively or additionally also take place in the upper fitting 12 or the lateral vertical fittings 11 of the sliding sash 1 a, 1 b. The Anbrin supply in the lower region of the main closing edge is useful, however, since from there, the closest attachment, or bottom guide of the wing is furthest away. The additional Ver not shown in the figures locking can be designed as a forcibly purely mechanically operated locking, but also as a locking mechanism driven by a locking motor or electromagnet.

In all of the following exemplary embodiments, locking takes place by means of a horizontally located locking bolt 51 , which locks the two wings 1 a, 1 b against one another. Alternatively, however, the locking of both wings 1 a, 1 b against the floor is possible, or especially with single-wing doors a locking against a fixed post, a wall or the floor.

An embodiment of the locking device 5 is shown schematically in FIG. 2. The figure shows a section of the sliding panel 1 a, 1 b in the almost completely closed and locked state. The locking device 51 horizontally mounted in a guide device 54 in the lower fitting 13 is pressed by a guide element 54 a against a friction wheel 52 and driven by this force. The friction wheel 52, which is also rotatably mounted in the fitting 13, interacts with a stationary friction surface 53 . The friction surface 53 can preferably be integrated in the bottom guide of the sliding sash. The actuation of the bolt 51 described below takes place using the movement and the kinetic energy of the wing 1 a.

The friction surface 53 is anchored longitudinally next to the wing 1 a in the ground, so that the friction wheel 52 rolls on the friction surface 53 in a positively guided manner when the wing 1 a is moved. Characterized the locking bolt 51 is moved over the friction wheel 52 when closing the wing 1 b in its locking position, in which it protrudes laterally beyond the main closing edge of the wing 1 a and engages with the Riegelaufnah me 5 b in the opposite wing 1 b. The movement of the wing 1 a is thus immediately converted into a movement of the locking bolt 51 . Pressing on the wings 1 a, 1 b perpendicular to the locking axis is prevented in the locked state. Conversely, when the wing 1 a is opened, the locking bolt 51 is moved into its unlocked position, it being fully inserted into the lower fitting 13 . It is not required that the friction wheel 52 is in active contact with the friction surface 53 over the entire door path. Only a sufficient distance is required to move the locking bolt 51 between the locking and the opening position. In order to facilitate the production of the active contact between the friction wheel 52 and the friction surface 53 , the friction surface 53 has a run-up slope 53 a on its side facing away from the main closing edge.

In an alternative arrangement, the friction wheel 52 can also be mounted in the bottom guide of the wing 1 a. This reduces the moving mass of the wing 1 a, which is particularly advantageous for lightweight designs.

Another embodiment of the locking device 5 is shown in FIG. 3. The locking bolt 51 is also in this embodiment in the lower loading 13 horizontally arranged in the wing plane and additionally tensioned against the force of a return spring 57 . The return spring 57 is supported between parts of the guide device 54 a and a thickening 51 b of the Rie yellowolzens 51 . The tensioning mechanism 6 , which is part of the locking device 5 , is arranged in FIG. 3 in the left part of the fitting 13 and consists of a sliding body 61 , which is anchored in the Bo the entrained driver 62 in a track 63 within the fitting 13 can be moved. The guideway 63 represents an inclined plane for the sliding body 61 with a lower starting position 63 a and a higher lying end position 63 b, the end position 63 b being oriented toward the main closing edge. The sliding body 61 is ge via a pulley 64 guided cable 65 with the lockable end 51 a of the locking bolt 51 Kop pelt. In the starting position 63 a at the lower end of the guideway 63 , the sliding body 61 is at the level of the driver 62 , while in the end position 63 b at the upper end of the guideway 63 it is higher than this and the driver 62 thus pass below the sliding body 61 can.

The locking bolt 51 is in the illustration in the locking position within the fitting 13th This prevents a locking and release lever 56 , which is arranged tiltably or rotatably below the locking bolt, whereby it projects with a locking lug 56 a in its path of movement that the locking bolt 51 comes into the locking position by the force of the prestressed return spring 57 . A spring, not shown, holds the locking and release lever 56 in the locking position shown. When the wing 1 a is closed, that is to say a right-hand movement, the locking and release lever 56 comes into abutment with its vertically downward triggering lever arm 56 b with a stop 55 arranged fixedly on the ground. Characterized the Arretierhe bel 56 pivots about its axis of rotation and releases the locking bolt 51 . This is moved into the locking position by the force of the return spring 57 , wherein connected via the cable pull 65 , the sliding body 61 is also moved back into its starting position within the guideway 63 .

When opening the wing 1 a, ie a left-hand movement, the sliding body 61 runs onto the driver 62 arranged fixed to the floor and is held by this while the wing continues to move in the opening direction. As a result, the sliding body 61 is displaced in the guideway 62 to the left and on the inclined plane upwards until it can pass the driver 62 when the higher end position is reached. When moving the sliding body 61 , the locking bolt 51 is pulled against the force of the return spring 57 in the fitting 13 via the cable 65 and at the same time locked in the unlocked position by the locking lever 56 . At the same time, the return spring 57 is biased for the next locking operation. The spring 57 thus serves as energy storage, which is loaded using the kinetic energy during the opening movement of the wing 1 a, in order to provide this energy for actuating the bolt 51 during the closing process.

FIGS. 4 and 5 show two variants of the above embodiment which are different in the tripping mechanism. For the sake of clarity, the tensioning device 6 which is still present is not shown in FIGS . 4 and 5.

Fig. 4 shows a mechanical release of the lock on the wing, a recorded 1 a linkage 59th A vertically arranged actuating rod 59 is mounted vertically displaceably within the wing 1 a, the lower end 59 a of the actuating rod 59 blocking the lockable end 51 a of the locking bolt 51 in the prestressed open position. The upper end 59 b of the actuating rod 59 protrudes beyond the upper edge of the wing and carries a horizontal slot-shaped recess 59 c, which faces the stop 55 . The stop 55 for triggering the lock is arranged in this case above the wing 1 a and carries an obliquely downwardly projecting projection 55 a, which cooperates with the recess 59 c of the actuating rod 59 . In that the wing 1 a runs onto the fixed stop 55 with the actuating rod 59 immediately before reaching the closed position, the obliquely downward projection 55 a engages in the recess 59 c. Due to the slope of the projection 55 a, the operating rod ben angeho 59 in its guide in the vertical direction and outputs the locked end 51 a of the locking bolt 51 free. Under the force of the return spring 57 , the locking bolt 51 then reaches the locking position. The locking takes place as well as the return and Arretie ren of the locking bolt 51 as already described in Fig. 3.

The stop 55 can also be coupled to a fixed sliding door lock arranged above the sliding leaf, so that the locking bolt 51 is only triggered when the upper fixed sliding door lock is actuated.

Instead of a mechanical triggering of the lock, FIG. 5 alternatively shows an electromagnetic triggering by an electromagnet 58 arranged above the locking lever 56 . In the locked state, the locking lever 56 lies in a horizontal orientation above the locking bolt 51 and engages with the locking nose 56 a behind the lockable end 51 a of the locking bolt 51 , which is thus held in the unlocked state against the force of the return spring 57 . Upon reaching the closed position, a locking lever arranged above the solenoid 58 is energized, whereby the locking lever 56 is attracted by the electromagnet 58 to pivot upwardly and releases the locking bolt 51st As described above, the locking bolt 51 is then moved by the return spring 57 into the locking position and engages in a recess 5 b of the second wing 1 b not shown Darge a.

Fig. 6 shows an embodiment in which the locking bolt 51 is actuated via a Bowden cable 7 . The Bowden cable 7 , which is arranged in the lower fitting 13 , has a shorter sheath 71 mounted between two support points 7 a, 7 b and a longer core 72 a, 72 b protruding from the sheath 71 at both ends. One end of the sleeve 71 is supported directly behind the rear end 51 a of the locking bolt 51 wing-fixed, the protruding from the sleeve 71 soul 72 a passed through the support 7 a and connected to the locking bolt 51 , z. B. by clamp connection. The second support 7 b for the sleeve 71 , which supports the other free end of the sleeve 71 , is located near the lower wing edge and at a greater distance from the main closing edge. The sleeve 71 is deflected by 180 degrees between the two support points 7 a, 7 b. The protruding from the second support 7 b end of the soul 72 b is also passed through the support 7 b and not fixed together with a fixed stop 73 . The stop 73 forms a stop for the axial movement of the soul when the wing is closed ge. When the stop position is reached, the axial outward movement of the locking bolt 51 begins.

The bottom cable 7 represents a mechanical transmission element by which the position of the locking bolt 51 is coupled with the wing movement. With an opening movement of the wing 1 a, the distance between the lower support point 7 b and the bottom-side holder 73 increases and the core 72 b fixed in the holder 73 is pulled out of the casing 71 by the door movement at the lower support point 7 b. Accordingly, it is retracted at the bolt side a supporting point 7, the core 72 a in the sleeve 71 and the core 72 a composites ne latch bolt 51 against the force of the return spring 57 fully retracted impact 13 in the Be. When closing the wing 1 a, the locking bolt 51 is moved by the return spring 57 from its unlocked position into the locking position, the coupling with the bolt 51 soul 72 a at the riegelsei term support point 7 a, made possible by the decreasing distance between underside support point 7 b and bracket 73 , is pressed out of the sleeve 71 .

An alternative embodiment of the invention is shown schematically in FIG. 7. The locking device 5 is arranged in the vertical fitting 11 of the main closing edge of the wing 1 a and has a horizontally displaceable locking bolt 51 and a likewise horizontally displaceable trigger bolt 81 . In the unlocked state, the release bolt 81 protrudes beyond the main closing edge of the wing 1 a and the locking bolt 51 is completely accommodated in the fitting 11 . In the closed position of the wing 1 a, the trigger bolt is pressed into contact with the main closing edge of the wing 1 b lying opposite in the fitting 11 , wherein it actuates a downstream gear 8 . About the gear 8 , the push-in movement of the release bolt 81 is converted into a locking movement of the locking bolt 51 . Through the use of the gear 8 , a larger locking path for the latch yellow bolt 51 is achieved for a small actuation path when the trigger bolt 81 is pressed in, which engages in a known manner in a locking receptacle 5 b in the opposite wing 1 b in the locking state. The locking bolt 51 can be returned to the fitting 11 when the door is opened, both via a tensioning device 6 of the type described at the outset and via a return spring acting on the locking bolt 51 .
