The sash and the fixed frame parts of a lift-slide door are well known, so that a reference to Figure 1a is sufficient. There are - in perspective view - the fixed space 41 and the movable (wing) door part 40, the sash 33 with handle or lever 2 for the built-in gear and the fixed track rail 10 shown, with the sliding sash is in its closed position.

Furthermore, it is known that the parts of the fitting, as far as they are associated with the wing, in the rabbet groove of the wing are arranged. This rabbet groove is usually of the Cover rail covered to fold.

In the illustration of the fitting of Figure 1 , it is assumed that this fitting is associated with a wing 40, which - as in Figure 1a - from left to right from the closed to the open position is displaced, after he by pressing the handle or Levers 2 has first been raised before it can be moved to the side in front of the fixed part 41 of the arrangement. When the door is opened, the passage opening is formed, that is to say in FIG. 1 from its left side.

In the example shown in Figure 1 , the fitting in the usual way from the already mentioned actuating lever 2 and the associated therewith and operated by this conventional transmission 1. The transmission 1 is formed so that upon pivoting of the lever 2 in the seaming groove and behind the cover rail 3 at least one push rod 3a is moved vertically up or down. As a rule, a vertical push rod 3a is displaced by the transmission 1 in the vertical direction by the actuation of the handle 2. The downward push rod 3a is coupled at its lower end with a known Eckumlenkung 4 at 6, wherein the Eckumlenkung a first carriage 5 is assigned, which in turn coupled via a connecting rod 8 with a second carriage 7 at the other lower corner of the wing actuation is. In a known manner, when lifting the push rod 3a when opening the wing, first a lifting movement is triggered on the two carriages 5 and 7, which can be moved by means of the handle 2 of the wing in Figure 1 to the right to open.

The two carriages 5 and 7 is a corresponding Rail 10 assigned, extending over the entire width of the to be cleared door opening and in addition to a the Displacement of the door corresponding path section extends. The Running rail 10 has on its top a special Rail area 11, on which the rollers of the two Carriage 5 and 7 sit up.

Usually, the push rod 3a on the vertical side of the Gear 1 associated with corresponding locking elements, the with corresponding spatially fixed counter elements in the Interlock locking position of the gear unit.

According to the invention, a further corner drive 9 is coupled to the second carriage 7 Preferably, the housing of the corner drive is combined with the carriage 7 to form a unit which extends angularly, wherein the carriage the horizontal leg and a part of the corner deflection the vertical leg of the Form building unit. By the corner deflection 9, the horizontal movement of the connecting rod 8 is deflected in the vertical direction in the region of the transmission 1 opposite to the spar. On the vertical leg of the corner 9 a vertical thrust element 21 is coupled. This thrust element 21 forms in the illustrated embodiment, a portion of a thrust reverser 12, which is shown in more detail in Figures 2 and 3 . The push direction reversing device is installed in the vertical fold on the opposite side of the transmission. The reversing device is in addition to the already mentioned thrust element 21 from a spatially fixed gear 22 and a parallel to the thrust element 21 vertically guided second thrust element 24th

If, in the closing movement, the pusher element 21 moves upwards in the vertical direction in FIG. 2 , the pusher element 24 of the reversing device 12 arranged parallel thereto simultaneously moves in the opposite vertical direction, that is, downwards.

The thrust element 24 is coupled to a rod-shaped engagement element 25, which extends up to the lower edge of the lower spar of the sash. The engagement element may have a box-shaped cross-section, while its lower end consists of two flat-bar-shaped and strongly shaped end sections 25a, 25b arranged at a predetermined mutual spacing. In Figure 2 , the running rail 10 is shown in cross-section in the plan view on the middle section of the rail portion 11 is provided for the rollers or wheels of the two carriages in plan view. It can be seen from Figure 2, that the two end portions 25a, 25b are arranged at a distance on both sides of the rail portion 11, so this does not affect. In the running rail 10, two cross-sections of the end portions 25a, 25b corresponding engagement openings are incorporated on both sides of the rail portion 11, with which the end portions 25a, 25b are in alignment in the closed position of the wing. The openings are in the area indicated at 10a, 10b.

If now in the closed position of the wing, the handle is pivoted into the blocking position, the thrust element 21 is moved upward in accordance with Figure 2, whereby by the rotation of the gear 22 which engages in corresponding rack portions of both thrust elements 21 and 24, the thrust element 24 down is moved. As FIG. 3 shows, at the same time the engagement element 25 in the sash rebate is also displaced downwards, so that the two end sections 25 and 25b come into locking engagement with the two engagement recesses 10a and 10b in the track rail 10. This is already very reliably locked on the side facing away from the handle side vertical side of the lower spar this spar of the wing with the fixed space running rail 10. It is very difficult to lever or lift the wing in this area from the outside so far that the end sections 25a and 25b reach out of locking engagement with the two engagement recesses 10a and 10b of the track rail 10. For many applications, such locking is already sufficient.

The engagement position shown in Figure 3 of the two lower End portions 25a and 25b in the engagement recesses 10a, 10b the running rail 10 is in the figures 3a and 3b again more clearly and on an enlarged scale. It will also evident that burglars working in the plane of the Wings are effective, in one direction, around the wing move from its closed position to its open position, can be reliably collected in the running rail 10. This can be done effectively by removing the forces from the Thrust reverser 12 are received and on the vertically movable engagement element 25 are transmitted, which these forces on the running rail 10 through the engagement the ends 25a, 25b deposited in the engagement recesses 10a, 10b become. The fixed to the casement screwed cover rail 20th Make sure that no game in horizontal Direction between the wing and the engagement member 25th arises, because the engagement element in the rabbet groove, which is from the Cover rail is covered, practically vertically guided play-free is.

Due to the additional corner drive 9 on the second carriage 7 with the associated pusher 21 the possibility is achieved by coupling the pusher 21 with a vertical in the associated sash led locking bar 13 a Locking of the upper spar at fixed parts of the arrangement to reach. Again, the locking of the wing takes place on the handle 2 remote from the vertical side, in the upper spar area on a space-fixed area of the whole Arrangement. As is apparent from Figures 2 and 3, the Pusher 21 with its upper end via a coupling 18 with de vertically guided locking rod 13 coupled.

Figure 4 shows the upper end 15 of the locking bar 13, in the unlocked state. In Figure 4 can be seen a section through the upper horizontal frame member 30, while looking at the wing 40 in side view of the rabbet groove, in which the locking rod 13 is arranged and guided. On the frame member 30 is in alignment with the central axis of the locking rod 13 a the end 15 of the rod in the locked closed position of Figure 5 receiving receptacle 31. This is part of the upper spar 30 and protrudes from the underside down. The arrangement is made in practice so that the opening and closing necessary wing movements are not disturbed. Thus, the wing can be lifted from the closed position of Figure 5 by the height difference 36 in the open position of Figure 4, without this movement is hindered by the receptacle 31. The receptacle may be provided on the underside of an upper, fixed to the frame frame 30 fixed space guide rail 16.

Preferably, the receptacle is a blind hole 31 in the Guide rail 16 is formed, which in the closed position End 15 of the locking bar 13 relatively tightly encloses and which is closed at its inner end 32. In the in Figure 5 shown closed position, the front side of the rod 13th practically sit on the bottom 32 of the blind hole. It can also be one some vertical play between the two areas remain. It can be seen that in this embodiment, at the only about the corner 9, the locking bar thirteenth is brought into and out of locking engagement, also one Reliable securing of the wing in the closed position against Levering out and moving in the opening direction achieved is because a levering by the abutment of the front side of the End portion 15 to the bottom 32 of the blind hole receptacle 31st is excluded.

It is advantageous, the depth of engagement of the section 15th in Reception 31 in each concrete case accordingly check and adjust if necessary. This is according to FIGS. 2 and 3 thereby possible that the lower end of the locking bar 13th coupled via an adjusting sleeve 18 to the pusher 21 is, after loosening the socket screws, the relative position of Rod 13 to the pusher 21 changed in the vertical direction and in the adjusted position by tightening the screws can be secured.

The locking bar 13 is in over its entire length according to small distances at the wing by elements led each side bending out of the Prevent locking rod 13 under high load.'One Guide at the top is shown at 17 in FIG. Corresponding guides 17 are shown in Figure 1 in the vertical spar arranged distributed of the wing.

Preferred is a combination of the two Locking options at the bottom and at the top Querholmbereich of the wing, as this overall in the figures already shown.

By the thrust reverser 12, the two Locking elements 25 and 13 simultaneously and synchronously, however in opposite directions in the vertical direction in and moved out of engagement with the fixed spacial elements become. This can be about the adjustment in the field of Socket 18 ensures that the front of the End portion 15 of the locking bar 13 at the bottom 32 of Muff-shaped receptacle for concern comes clearly before the lower ends of the end portions 25a, 25b when lifting the wing out of engagement with the associated engagement recesses 10a, 10b the running rail 10 can get.

The combination of both locks makes a violent one Opening the grand piano virtually impossible, unless it becomes the Wing filling smashed and the lever 2 from the outside accordingly operated to release the lock. However, too corresponding locking devices for the lever. 2 known, which exclude unauthorized operation.
