1 shows a two-leaf door 1, which comprises a passive wing 2 and an active wing 3, which are arranged in a door frame 4 on hinges 5. The passive wing 2 can be fixed in the door frame 4 by means of upper and lower switch lock 6, which is arranged on the upper or on the lower front side. The switching locks 6 are parallel to the vertical

Longitudinal sides of the passive wing 2 arranged locking bars 7 with a central lock 8, i. with an actuating device of the lock 8, operatively connected. The lock 8 has one with a coupling gear

cooperating pusher 8d, wherein the coupling gear a

Rotary movement of the pusher 8d in simultaneous thrust movements of the

Locking rods 7 converts. The locking bars 7 are an upper locking bar and a lower locking bar. By depressing the pusher 8d, the locking bars 7 are moved in the direction of the lock, i. moved in the direction of the actuating device of the lock 8, and it will, as described below, the switching locks 6 unlocked. In this case, therefore, the upper locking bar 7 is moved down and the lower locking bar 7 upwards.

The active wing 3 has a lock 9 with a pusher 9d, wherein the lock 9 further comprises a latch and a latch. The latch and the bolt are designed and arranged so that they engage in a arranged on the passive wing 2 strike plate.

Figs. 2 to 8 show the structure of the upper switching mechanism 6 in detail. Figures 9 to 14 show the functions and the operation of the upper switching mechanism 6 in detail. The position assignments "top" and "bottom" selected in the following description with respect to these figures correspond to the installation position of the upper switch lock 6. For the lower switch lock 6, these position assignments are to be interchanged. Fig. 2 shows the upper portion of the switching mechanism 6, wherein in the illustrated switching position the latch 1 1 engages in a receptacle in the strike plate 4s. As a result, the passive wing 2 is fixed to the door frame 4.

The components of the switch lock

Reference is made to FIGS. 2 to 5. The switching mechanism 6 has a latch 11, and a bearing block 13 on which the latch 1 1 is pivotably mounted. The switching mechanism 6 further has an auxiliary latch 12 and a shift fork 15. The bearing block 13, the auxiliary latch 12 and the shift fork 15 are in axial

Direction movably mounted in the housing of the switching mechanism 6. In Figure 2, the shift rod 17 can be seen. The shift rod 17 is connected to the locking bar 7 and operatively connected to the actuator 8.

The case 1 1 and the bearing block 13

Reference is made to FIG. 2. The switching mechanism 6 has the latch 11. The case 1 1 engages in the closed position of the door in a on the door frame. 4

arranged strike plate 4s.

Reference is made to FIGS. 4a to 4c. The case 1 1 is pivotally mounted on the bearing block 13. The case 1 1 has a through hole 1 d for receiving a journal 1 1 z (FIG. 4d), which engages through a through hole 13d formed in a bearing block 13 (FIG. 4b) or is mounted in a bearing block on a differently designed pivot bearing. The bearing block 13 engages with its upper end portion in a slot formed in the lower end portion of the case 1 1 a slot-shaped recess (Fig. 4d). The bearing block 13 is by means of a return spring, not shown in the extension direction yet above, so from the actuator 8 away, acted upon.

Reference is made to FIGS. 5a to 5c. The case 1 1 has in its lower end portion of further opposing recesses 1 1 r, engage in the spring-loaded locking pins 14, with a shift fork 15th

cooperate (Fig. 5a). The shift fork 15 is used to lock and unlock the case 1 first Fig. 5b shows the case 1 1 in the locked state in which the locking pins 14 engage in the recesses 1 1 r and thus prevent rotation of the case 1 1. In this position, the prongs of the shift fork 15 push the locking pins 14 into the latching recess 1 1 r of the case 1 first As a result, the case 1 1 can not be rotated. The locking pins 14 are mounted radially displaceably in the bearing block 13. The locking pins 14 act with a device

together, which moves the locking pins 14 to the outside when the locking pins 14 are disengaged from the tines of the shift fork 15. This device can be controlled by the pivotal movement of the case 1 1. It can be provided that corresponding to the case 1 1 and the locking pins 14

Carrier surfaces or stop surfaces formed. The locking pins are moved in this way outward when the tines of the shift fork 15 do not act on the locking pins 14. Additionally or alternatively, the locking pins can also be acted upon by associated springs radially outward.

Fig. 5c shows the case 1 1 in the unlocked state in which the case is in a rotated about its bearing pin 1 1 z position and the locking pins 14 are not engaged with the recesses 1 1 r. The trap 1 1 is now rotatable. In this rotatable position, the shift fork 15 is moved with respect to the case 1 1 down. The locking pins 14 do not engage in shifted down shift fork 15 in the locking receptacles 1 1 r the case of 1 1. This means that the case 1 1 is now pivotable about the axis of the journal 1 1z.

The Schaltqabel 15

Reference is made to FIG. 4c. The shift fork 15 is formed of a tube having two at its upper end portion

opposite fork tines 15z has beveled switching edges 15f, which cooperate with the aforementioned locking pins 14. The forks 15z are guided in guide slots 13f of the bearing block 13.

Reference is made to FIGS. 3 and 8a and 8b. At the lower end portion of the shift fork 15, two opposing arms 15a are arranged, their directed to the forks 15z faces

Form stop surfaces 15a for locking pins 16, as will be described below. The shift fork 15 can be reset by means of a restoring spring 15r (FIG. 3) into a starting position in which the latch 1 1 is locked.

The auxiliary trap 12

As shown in FIG. 3, the auxiliary latch 12 surrounds the latch 1. The auxiliary latch 12 has a rohrformigen body, in which the shift fork 15 and the bearing block 13 is received with the case 1 1. The rohrformige body of the auxiliary latch 12 has a plurality of slot-shaped axially extending recesses. In the upper end portion, the tubular body has a trap body with a slit-shaped recess for the passage of the case 1 1. The rohrformige body of the auxiliary latch 12 is formed in several parts. It is composed of an upper portion 12o and a lower portion 12u.

To facilitate assembly, the lower portion 12u of the auxiliary latch 12 is formed of two half-shells. The composite rohrformige body of the auxiliary latch 12 is acted upon by means of a return spring, not shown in the figures in the extension direction upward, ie away from the actuator 8. The function of the auxiliary latch is described below: Reference is made to FIG. 2: The auxiliary latch 1 1 detects whether the door leaf is in the closed or open position. In the position shown in Fig. 2, the auxiliary latch 12 abuts the strike plate. In this position, the auxiliary latch 12 is partially retracted into the switching mechanism 6 and is prevented by the striking plate 4s to extend to its fully extended position.

The auxiliary latch 12 also serves to block and release the shift fork 15. As can be seen in Figure 3, the auxiliary latch 12 in its lower portion on a control cam 12s, which serves to displace locking pins 16. The locking pins 16 are controlled by the 12 formed in the lower portion of the auxiliary latch 12 in slit-shaped recesses cam. The control cams 12s have two aligned with the longitudinal axis of the auxiliary latch 12 linear portions of different height, which are connected by an inclined switching portion. The locking pins are so displaced by the control cams 12s of the auxiliary latch that the locking pins 16 protrude into the path of movement of the shift fork 15 and a movement of the shift fork 15 upwardly opposed. In Figure 3, the release position shown in the locking pins 16 is not in the trajectory of the

Protruding shift fork 15. In Figure 14, the blocking position is shown: Here, the locking pin 14 can be seen, on which an arm 15a of the shift fork 15 is applied. Characterized that the arm 15a of the shift fork 15 bears against the locking pin 16, the movement of the shift fork 15 is prevented here upwards. This means that in this position, the case 1 1 is pivotable.

The shift rod 17

The shift rod 17 is shown alone in FIG. 7b. The shift rod is in operative connection with the actuating device of the lock 8 (FIG. 1). As shown in Figure 7a, the shift rod 17 extends through the shift fork 15. The upper end portion of the shift rod 17 has a recess 17a, in which a transverse pin is inserted (Fig. 7b). This cross pin cooperates with the shift fork 15. When retracting the shift rod 17, the shift fork 15 is taken, so that the shift fork 15 is moved away from the case 1 1. The shift rod has a circumferential latching groove 17r. In this locking groove locking elements 19 can retract (see Fig.7a and 7b), which prevent movement of the shift rod 17 upwards. The locking elements are described in more detail below.

The bearing element 18th

FIGS. 6a and 6b show a bearing element 18. The bearing element 18 constructed from two half-shells has first guide recesses 18e, in each of which a detent element 19 sprung with a spring not illustrated in the figures is guided. The locking element 19 cooperates with the circumferential locking groove 17r, which is formed on a shift rod 17 together (see Fig. 7a and 7b). The locking element 19 is of a in controlled lower portion of the shift fork 15 formed control cam 15s (see Fig. 4c). The cams 15s have two aligned with the longitudinal axis of the shift fork 12 linear portions of different heights, which are connected by an inclined switching portion.

The bearing element 18 further has second guide recesses 18fz, in each of which a sprung locking pin 16 described above in FIG. 3 is guided.

FIGS. 9 to 14 show different operating states of the switching mechanism 6.

Fig. 9 shows the switching mechanism 6 with locked latch 1. The switching rod 17 connected to the upper locking bar 7 assumes its upper position.

Fig. 10 shows the switching mechanism 6 with unlocked case 1 first The switching rod 17 connected to the upper locking bar 7 assumes its lower position.

Fig. 1 1 shows the switching mechanism 6 with unlocked and tilted trap 1. 1

Fig. 12 shows the switching mechanism 6 with tilted and in the housing of the

Switch lock 6 retracting latch 1 1.

Fig. 13 shows the switching mechanism 6 with retracted trap 1 1 and extended auxiliary trap 12. And the 14 shows the switching mechanism 6 with the latch 1 1 extended and the auxiliary latch 12 extended.

In the following, the operation of the switching mechanism 6 will be explained with reference to the aforementioned figures 9 to 14. Here, in FIG. 9, the

Switch lock 6 shown with locked passive wing. FIG. 14 shows the switching mechanism 6 with the passive wing fully open. In FIGS. 10, 11, 12 and 13, the switching mechanism 6 is shown at various stages during the opening of the passive wing 2.

The locked closed position in Figure 9 / end position

FIG. 9 shows the switching mechanism 6 when the passive wing 2 is locked. The switching rod 17 connected to the upper locking bar assumes its upper position. The case 1 1 is fully extended and engages in a her assigned, not shown recording bolt receptacle of the strike plate on the door frame. The auxiliary latch 12 is only partially extended. A complete extension of the auxiliary latch 12 is prevented by an arranged on the door frame, not shown strike plate. Next, the shift fork 15 is in its upper position, the forks 15z urge the locking pins 14 in the recesses 1 1 z and thus prevent rotation of the case 1 1. This position of the case 1 1 on the shift fork 15 is shown in Figure 5b. The case 1 1 is rigid in this position, that is torsionally rigid and / or not pivoting, as the

Shift fork 15 holds the case 1 1 on the locking pins 146 in its illustrated rotational position. The intermediate position in FIG. 10

FIG. 10 shows the switching mechanism 6 after actuation of the actuating device of the lock 8. The actuation can take place manually via a pusher 8d. But it is also possible that the actuating device is actuated by a motor. Upon actuation of the lock 8, the locking bar 7 is displaced in the direction of the lock 8. The connected to the upper locking bar 7

Shift rod 17 is also retracted in the direction of the lap 8. In the illustrated embodiment, the shift rod 17 is formed as the upper portion of the locking bar 7. When retracting the shift rod 17 in the direction of the lock 8, the shift fork 15 is moved by the shift rod 17. The trap 1 1 remains in its fully extended

Position. The fact that the shift fork 15 is retracted, are the

Forks 15z out of engagement with the locking pins 14. The locking pins 14 no longer engage in the latching recess 1 1 r the case 1 1 a. As a result, the blocking of the case 1 1 is repealed. The trap 1 1 is not rigid in this position, i. it is pivotable, since the shift fork 15 at a distance, that is out of engagement of the locking pins 14 is.

In the retracted state of the shift rod 17 engages the supported in the bearing element 18 locking element 19 in the locking groove 17r of the shift rod 17 a. The locking element 19 holds the shift rod 17 in its retracted position in or on the wing-fixed bearing element 18 and prevents movement of the

Shift rod 17 to the case 1 1 out. The passive wing 2 is no longer locked in this position and can be opened by pressing. In the position shown in Figure 10, the auxiliary latch 12 is partially extended, the extension of the auxiliary latch 12 is effected by application of a spring, not shown, and limited not shown in Figure 10 strike plate. The intermediate position in FIG. 11

Figure 1 1 shows the switching mechanism 6 during the opening of the passive wing 2. The positions of the auxiliary latch 12, the shift fork 15, the locking element 19 and the shift rod 17 are unchanged from the position shown in Figure 10. Only the case 1 1 is pivoted, which by striking the case 1 1 to the edge of the bolt receptacle of the door frame side

Striker is caused when pressing the passive wing 2. The case 1 1 is no longer rigid in this switching position, since the case 1 1 assumes a pivotal position in which the locking pins 14 are not in the

Locking recesses of the trap 1 1 r intervene. In this pivoting position, the latch 1 1 remains pivotal, regardless of the position of the

Shift fork 15.

The intermediate position in FIG. 12

FIG. 12 shows the switching mechanism 6 in a further position during the opening of the passive wing 2. The positions of the auxiliary latch 12, the latching element 19 and the switching rod 17 are unchanged from the positions shown in FIGS. 10 and 11. In Figure 12, the case is 1 1 on the door frame side lock plate and now no longer attacks in the

Lock catch of the strike plate. By the system of the case 1 1 on the strike plate of the bearing block 13 with the case mounted thereon, against the action of the spring 13r, displaced towards the actuator 8 down. The shift fork 15 is shifted even further towards the position shown in FIGS. 10 and 11. The shift of the shift fork 15 takes place in that the bearings mounted on the bearing block 13

Locking pins 14 on the upper sides of the switching prongs 15 of the shift fork 15th abut and a displacement of the bearing block 13 down and thus causes a shift of the shift fork 15 down. It should be noted that the shift fork 15 in the position shown in Figure 12, the locking pins 14 can not push into the locking receptacles of the case 1 1, since in pivoted case 1 1, the locking receptacles 1 1 are not aligned with the bearing 13a of the locking pins 14. This means that the latch 1 1 in the position shown in Figure 12 is pivotable and not fixable. The case 1 1 is still in the position as shown in Figure 1 1, in which the case 1 1 is not detected by the switching prongs 15z.

The intermediate position in FIG. 13

In contrast to FIG. 12, the auxiliary latch 12 in FIG. 13 no longer rests against the striking plate and has moved completely upwards under the effect of the spring acting on it. The displacement of the auxiliary latch 12 upwards to its fully extended position causes the locking pins 16 mounted in the wing-fixed bearing element 18 to be displaced by the control edge 12s of the auxiliary latch 12 so that the locking pins 16 move into the

Movement range of the shift fork 15 protrude, because the locking pins 16 are still applied by the slope of the control edges 12s.

FIG. 13 shows the switching mechanism 6 in a further position during the opening of the passive wing 2. The positions of the latching element 19 and the switching rod 17 are unchanged relative to the positions shown in FIGS. 10 and 12. The trap 1 1 is also still in abutment on

Door frame side strike plate, so that the position of the case 1 1, the

Bearing 13 and the shift fork 15 with respect to that shown in Figure 12 Position are unchanged. Only the auxiliary trap 12 is no longer on

Striking plate on.

The unlocked open position / end position Figure 14 shows the switching mechanism 6 in its open position

Passive wings 2. In this position, the case 1 1 is no longer on

on the door frame-side strike plate and is fully extended and the case 1 1 is its non-rotating rigid pivotal position. The shift fork 15 is associated with a spring 15r, which is supported on the wing-fixed bearing member 18 and the shift fork 15 in the direction of the extended position of the associated latch 1 1 applied. The bearing block 13 is associated with a spring 13r, which is also supported on the wing-fixed bearing block 18 and the bearing block 13 in the direction of the extended position of the associated latch 1 1 applied. Under the action of the spring 13r, not shown, the bearing block 13 is urged together with the latched thereon in its fully extended position. The shift fork 15 is urged upward by the action of the spring 15r. The fact that the locking pins 16 in the

Extend range of movement of the shift fork 15, the extension of the shift fork 15 is still limited above. The locking pins 16 are in this case on the stop surfaces 15a of the shift fork 15, so that when extended

Auxiliary latch 12 is prevented from further movement of the shift fork up and the shift fork 15 is held by the locking pins in a middle position. In the open position of the passive wing shown in Figure 14, the position of the locking element 19 and the control rod 17 relative to the position shown in Figures 10 to 13 remains unchanged. The locking element 19 is still applied to the locking groove 17 r of the control rod, whereby the control rod is held in its retracted position. The following are the operations in the transfer of the switching mechanism 6 of the open position of the passive wing 2 in the locked position of

Passive wing 2 will be explained.

The starting point is the position shown in FIG. 14, which shows the switching mechanism 6 when the passive wing is open. Here are both the auxiliary latch 12 and the bearing block 13 with the attached thereto case 1 1 in their complete

extended position. The shift fork 15 is held by the locking pins 16 at a distance to the case 1 1. The shift fork 1 1 is disengaged from the case 1 1. This means that the case 1 1 is tiltable. Next is that

Locking element 19 on the locking groove 17 r of the control rod to 17, whereby the control rod 17 is held in its retracted position. When closing the passive wing 2 comes as the first case 1 1 in abutment against the

Striker plate (Fig. 13). As a result, the first case 1 1 is pivoted. The positions of the shift fork 15, the bearing block 13, the auxiliary latch 12 and the control rod 17 remain unchanged. This position of the switching mechanism 6 corresponds to the position shown in Fig. 14 with the difference that the case 1 1 is pivoted to the auxiliary case. By further tightening the

Passive wing 2, the bearing block 13 is inserted with the attached thereto case 1 1 in the switch lock 6. In the course of tightening the

Passivflügels also comes the auxiliary latch 12 into abutment against the strike plate (Fig. 12) and is inserted together with the bearing block 13 and the case in the switch lock 6. This position of the switching mechanism 6 corresponds to the position shown in Figures 12 and 12a with the difference that the case 1 1 is pivoted to the auxiliary case. When the auxiliary latch 12 retracts, the control cams 12s come out of contact with the locking pins 16 (see FIG. 12a). The locking pins 16 are radially not shown by springs moved back to their original position. This means that when partially retracted auxiliary latch 12, the locking pins 16 no longer rest against the stop surfaces 15a of the control fork 15 and the control fork 15 is no longer prevented from moving upwards. The control fork will then

Fedebeaufschlagt pushed towards the trap 1 1. When moving upward, the switching prongs 15z come to the locking pins 14 and urge the locking pins 16 in the locking receptacles 1 1 d of the case 1 first As a result, the case 1 1 is fixed with respect to the latch bracket 13, that is no longer pivotable.

Once the passive wing 2 has then reached its closed position, the trap is no longer on the strike plate. Under spring action, the control fork 15 and the bearing block 13 are transferred with the fixed thereto case 1 1 in their fully extended positions. This locking position is shown in FIG.

During the movement of the control fork 15 in its extended position, the control cam 15s comes into contact with the latching element 19. The latching element 19 is thereby pushed outward in the radial direction out of the latching groove 17r of the control rod 17. The control rod 17 and coupled to the control rod 17 locking bar 7 are then no longer fixed by the locking element 19. The locking bar 7 can then also go up.

Essential in the switching mechanism 6 of the present invention is that the shift rod 17, and thus the locking bar 7 coupled thereto, only then is not fixed by the locking element 19 when the shift fork is moved upwards. The shift fork can only go up when the Auxiliary latch 1 1 by the strike plate in the switch lock 6 partially

retracted and is prevented by the strike plate on the extension.

The upper and lower locking bar 7 and 6 are connected via a coupling mechanism of the lock 8, d. H. coupled via a coupling mechanism of the actuating device of the lock 8 with each other. This means that the lower

Locking rod 7 can then extend into the bottom recess only when the locking element 19 is no longer engaged in the locking groove 17 r of the control rod 12 and thus has released the control rod. As shown above, the locking element 19 is displaced by the control cam 15s of the shift fork 15, so that the shift fork can fully extend when the case 1 1 is extended in the door frame side recording.

Further, in the case of the lower locking bar, a gravity compensation of the components is provided by spring action vertically upwards, so that the case 1 1 does not extend downwardly under gravity alone without being acted upon by the locking bar. The extension path of the auxiliary latch 12 is basically already limited by stop.

In a particularly preferred modification of the illustrated embodiment, it is provided that the upper locking bar via a spring in

Locking direction is acted upon and that the auxiliary latch with the upper locking bar cooperates such that the upper locking bar is held in its unlocked position, as long as the closed position of the wing is not reached, and that the upper locking bar is connected to the lower Rieglstange via a coupling gear, the connecting two locking bars for a forced mutual movement. By controlling the case 1 1 of the lower locking bar by the upper switching mechanism 6 is achieved that the case 1 1, the lower locking bar with open passive wing 2 causes no damage to the bottom of a walk-through door 1 room. Rather, the lower locking bar is retracted despite the pressed pusher 8d of the passive wing 2, as shown in Fig. 13, and only leaves again when the case 1 1 is completely extended when closing the passive wing 2 in the strike plate 4s in the door frame side recording.

In preferred embodiments, such as e.g. in the embodiment shown in the figures, it is provided that the

Actuating device 8 via a handle 8b or via a motorized actuating drive, not shown, acts on the latch 1 1 only in the sense of unlocking the lock, i. only to the case 1 1 in the

To move unlocking position or the case 1 1 at least freely switch that they can go to the unlocked position. The locking of the

Castle automatically takes place automatically, i. the case 1 1 is self-locking, without a manual or motorized operation of the

Actuator 8 is required. In the case shown in the figures, the locking takes place automatically as soon as the wing is brought into the closed position while an actuation of the auxiliary latch 12 and an actuation of the latch 1 1 is carried out by stop on the frame and / or on the strike plate. In the illustrated embodiment, said two conditions for the operation of the lock are required. In modified

Embodiments, as have also been explained in connection with the embodiments, the operation of the auxiliary latch can be provided as a sole condition for the operation of the lock. FIG. 15 shows a further embodiment of a lock.

This lock has coincident with the lock previously described a pivotally mounted on a bearing body 13 case 1 1, a switching element 15 and an auxiliary latch device 12. The essential difference to the lock of Figures 1 to 12 is that the lock of FIG. 15 a

Clamping ring 20 for locking the bolt control member 17 and on

Actuator 19 has. The clamping ring 20 and the actuator 19 are intended in

Described below.

The clamping ring

The clamping ring 20 is displaceably mounted in the lower region of the sleeve-shaped housing body 6g facing away from the peg 1. The clamping ring 20 has substantially the shape of a hollow cylinder. The clamping ring 20 has a projection with which the clamping ring 20 is mounted against rotation in a slot 6gs in the housing body 6g.

Above the clamping ring 12, the auxiliary latch device 12 is slidably disposed in the housing body 6g. The Hilfsfalleneinrichtungl 2 is at least partially supported on the clamping ring 20. The clamping ring 20 and the

Auxiliary trapping device 12 are acted upon by a helical compression spring 20r in the direction of the case 1 1 out. The helical compression spring 20r is supported on a support ring 20rs. The support ring 20rs has three projections, with which the support ring 20rs fixed to the housing can be inserted into the housing body 6g. For this purpose, the housing body 6g has three corresponding insert receivers 6ge for the support ring 20rs. The bolt control member 17 passes through the clamping ring 20 from below coaxially through the coil spring 20r and the support ring 20rs cross-reaching. The auxiliary trapping device 12 is supported on the upper side of the clamping ring 20. In the closed position of the door, the auxiliary latch device 12 by the

Frame, preferably operated by a frame side mounted striking plate and thus the clamping ring 20 displaced by the auxiliary latch means 12 against the action of the helical compression spring 20r to the lower end of the housing body 6g out. In this position, the axis of the hollow cylindrical clamping ring 20 is aligned with the axis of the bolt control member 17. In this position, the bolt control member 17 is only encompassed by the clamping ring 20, with a certain clearance between the outer diameter of the bolt control member 17 and the inner diameter of the clamping ring 20 is present. The

Latch control member 17 is in this position by the clamping ring 20th

freely movable through without clamping.

When the auxiliary latch device 12 no external forces act, the auxiliary latch device 12 and the clamping ring 20 by the force of

Pressed helical compression spring towards the case out. On its one side, the clamping ring 20 is held by its projection in the upper end of the slot 6gs of the housing body 6g. On its side opposite the projection, the clamping ring 20 is displaced upward due to the force of the helical compression spring 20r. In this position, the clamping ring 20 is tilted to the bolt control member, i. that the axis of the hollow cylindrical clamping ring 20 is no longer aligned with the axis of

Latch control member 17 is aligned. The bolt control member 17 is replaced by the

Clamping ring fixed in clamping engagement, so that the bolt control member 17 is clamped immovable when the auxiliary trapping device 12 is extended. Depending on the position of the auxiliary trapping device 12 so the bolt control member 17 is controlled via the clamping ring 20. At the frame side

acted auxiliary trap device 12, as is the case with the door closed, the bolt control member 17 is free to move. When open

Door leaves, when the auxiliary latch is extended, the extension of the

Latch control member 17 prevented case.

The actuator

The actuator 29 is inserted at the falling end of the bolt control member 17. The actuator 29 has at its end facing away from the bolt control member 17 end a widened head, which serves to cooperate with the switching element 15. It is essential that the actuator 29 is variable with respect to its depth in the bolt control member 17 can be used. By this is meant that the head of the actuator 29, the fall-side end of the

Latch control member 17 preferably variably adjustable more or less far surmounted. It can be provided that the actuator 29 has an external thread and the bolt control member 17 is provided at its fallenseitigem end with an internal thread. In this case, the height at which the head of the actuator 29 projects beyond the bolt control member 17, by corresponding

Screwing be variably adjusted. Alternatively, it can be provided that the bolt control member 17 has a plurality of locking receptacles, so that the actuator 29 can be inserted at different heights in the bolt control member 17.

The operation of the bolt control member 17 and the actuator 29 is the following. Upon actuation of the actuating device 18 by a handle or a motor drive device, the bolt control member 17 moved together with the attached actuator 29 of the case 1 1 and on the switching member 15. In the course of this movement, the head of the actuator 29 reaches a driving edge of the switching member 15, so that in this case the switching member 15 is taken from the actuator. By distancing the switching element 15 of the case 1 1, the case 1 1 is transferred to its pivotal position, since the forks of the switching element 15 come out of engagement of the blocking pins.

Characterized in that the actuator 29 can be used in variable depth in the bolt control member, it can be adjusted whether the operating member 18, the switching member 15 is taken immediately or only after a certain actuation travel of the bolt control member 14. Whether the switching member 15 at an actuation of the actuator 18 immediately from the bolt control member 17 or only in the course of the actuation path of the

Bolt control member 17 is taken, depends on how the lock is to be used.

When using the lock as the top lock on a passive leaf of a two-leaf door can be provided that the lock with a

Fallen / Riegelauswerferschloss the passive leaf works together. In such use of the lock, it is important that the locking position of the latch 1 1 of the castle is only canceled after the ejector of the trap / Riegelauswerferschlosses have been operated. In this case, in the assembly of the lock, the actuator 29 is inserted into the bolt control member 17, that in the locking position of the lock between the head of the actuator 29 and the switching member 15 is a relatively large distance. When using the lock as obenbengelnung on a single-leaf door, it is desirable that the Verrieglungsstellung the case 1 1, ie the

Non-pivoting the case 1 1, immediately upon actuation of

Actuator 18 is released. In this case, at the

Assembly of the lock, the actuator 29 is inserted into the bolt control member 17 that in the locking position of the castle between the head of the actuator 29 and the switching element 15 is as small a distance as possible. This means that the actuator 29 is inserted relatively far immersed in the bolt control member 17.

Concerning the locking process is provided in the embodiment shown in FIG. 15 that the case 1 1 with the

Hilfsfalleneinnchtung 12 and / or the bolt control member 17 so

cooperates, that the case 1 1 can be brought by a closing plate side actuation of Hilfsfalleneinnchtung 12 in its Verrieglungsstellung and / or freely switchable, without the need for a closing plate side actuation of the case 1 1 is required.

It is provided here that the release device cooperates as one with the latch control element 17 and / or the latch 1 1

Clamping device 20 is formed, and

in that the auxiliary trap device 12 interacts directly with a release device of the latch control element 12 and / or the latch 1 1. In the in the preceding figures 2 to 14 shown

Embodiments is in contrast to this provided that the case 1 1 cooperates with the Hilfsfalleneinnchtung 12 and / or the bolt control member 17 such that the case 1 1 can be brought into its locking position and / or is releasable when a closing plate side actuation of

Help trap device 12 by retracting the auxiliary trapping device 12 and a closing plate side actuation of the case 1 1 by pivoting the case 1 1 is done.

Figure 16 relates to a modified embodiment in which the

Pivot trap 1 1 via a spring 1 1f in the illustrated in Fig. 16

Pivoting position is applied. This pivot position is referred to below as the first pivot position. Fig. 16 shows only the modified in this embodiment assembly of the case 1 1 with the spring 1 1 f. It concerns the assembly, which for the preceding

Embodiment in Fig. 4d is shown. The rest of the construction and the

Functions of the modified embodiment correspond to the

Embodiment of Figures 1-15.

The spring 1 f is designed as a leg spring. It is supported on the bearing body 13, in which a bearing pin 13z, which is inserted in the bearing body 13, engages in a receiving hole in the one leg of the spring 1 1f, the other leg of the spring engages in a receiving hole 1 1o in the case of the first 1 on.

The only functional difference of this modified

Embodiment compared to the preceding embodiment consists only in that the pivotal latch 1 1 is pivoted by the spring 1 1f respectively in the first pivot position, so that in the open position of the door 1, the latch 1 1 occupies this first pivot position and so that even in the closed position the door the latch 1 1 occupies this first pivot position. This first pivot position is also present when the door moves from the open position into the closed position and the case 1 1 with her Incline on the frame comes into abutment and the case is also drawn in the bar rod extension direction in the door.

The second pivot position against the action of the spring 1 1f is obtained only temporarily, when the by the handle 8d (see Fig. 1) operated locking bar 7, the pivoting of the case 1 1 releases and during this operation of the handle 8d the case 1 1 at Opening the door is pivoted by stop on the frame in the second pivot position and the case is retracted by moving in locking bar extension direction in the door leaf. Immediately after reaching the closed position of the door, the pivotal latch extends and is returned by the spring 1 1 f in the first pivot position.

This reset of the case 1 1 from the second pivot position to the first pivot position and the extension of the case takes place every time the

Stop position between trap and frame is canceled. This is the case when the door has been moved from the closed position to the open position.

But this is the case when the stop position of the case and frame, which results in the closed position upon application of the door in the opening direction, is still canceled in the closed position and the door in the

Closed position remains. In this case, the case 1 1 is pivoted back by the spring 1 1 f in the first pivot position.

The spring action of the case 1 1 with the door open has the consequence that in the open position of the door, the case 1 1 is always in the first pivot position. Here, the case 1 1 in a position in which the pivoting of the case 1 1 can not be blocked by the shift fork 15. The case 1 1 can not be blocked by the shift fork, because the shift fork 15 at opened door as in the previous embodiment by the

Locking pins 16 is held in its the latch 1 1 non-blocking position in which it has been brought by the unlocking operation when opening the door and the shift fork 15 is out of engagement with the latch 1 1. Only in the closed position of the door is the shift fork 15 by the action of the auxiliary latch 12 out of engagement of the locking pins 16. In this switching position, the shift fork 15 blocks the case 1 1. This blocking occurs when the case 1 1 is in the first pivot position. The spring 1 1f acts as already explained on the case 1 1, to the effect that the spring 1 1 f the case both in the

Closed position as well as in the open position of the door in the first

Applied pivot position. This means that in the closed position of the door, in which the shift fork 15 is in its position blocking the pivoting of the latch, the pivotability of the case 1 1 is blocked by the shift fork 15. This has the advantage that malfunctions are avoided, which arise when not present spring 1 1 f in the closed position of the door after unlocking the shift fork 15 by actuation of the locking bar 7, the case 1 1 is brought into its second pivot position. The second pivot position of the case 1 1 adjusts itself by a stop of the case on the frame when the door in the closed position in

Opening direction is acted upon.

In the absence of the spring 1 1 f, this second pivot position of the case 1 1 would remain, even if the door is not subsequently opened, but the case 1 1 comes out of attack of the frame and the door remains in the closed position. In the absence of the spring 1 1f the trap 1 1 would engage with its second pivotal position and in the frame-side receptacle. However, since the case in the second pivot position by the switching device is not blocked, in this case, the case 1 1 would not locked, ie it would be in an extended non-locking position. By the inventive case 1 1 f such a malfunction is avoided. A particular advantage of the lock is that when the door is open, the lock against tampering by manually pressing the auxiliary latch 12 and / or the case 1 1 is secured. This means that by depressing the auxiliary latch 12 and / or the case 1 1 with the door open no extension of the lower locking bar is triggered. The movement with the lower locking bar motion-coupled control rod 17 is in each case by the

Locking elements 19 held. In the illustrated embodiment, the pivoting of the case 1 1 is released at the same time in these cases, and thus does not block the pivoting. When the door is open, the bearing block 13 with the case 1 1 mounted thereon and the auxiliary latch 12 are in their respective positions extended out of the lock. However, the shift fork 15 is held by the locking pins 16 in a retracted position, wherein the locking pins 16 abut against the stop surfaces 15 a of the shift fork 15. This means that the case 1 1 is free to pivot, since the shift fork 15 is in its retracted position and thus out of engagement with the case 1 1, that is, the blocking elements 14 block the pivoting of the case 1 1 not. When the door is open, the control rod 17 is also blocked by the locking elements 19.

In the following, it is stated that when the door leaf is open in case a) by the sole manual depression of the auxiliary latch 12 or in case b) by the common depression of latch 1 1 and auxiliary latch 12, the locking of the Castle is not triggered. Only in the case of c) the lock of the lock is triggered, that is, when pressed-in auxiliary latch 12 and simultaneously depressed latch 1 1 then the latch 1 1 is released while the auxiliary latch 12 remains in its depressed actuated position.

To a) Squeezing in the auxiliary trap with the door open

If the auxiliary latch 12 is manually pressed into the lock interior with the door open, the control cams 12s of the auxiliary latch 12 come out of contact with the locking pins 16. The springs, not shown, which act on the locking pins 16 in their position releasing the shift fork 15, the locking pins 16 but do not relocate. This is due to the fact that the shift fork 15 is spring-loaded in the extension direction by the spring 15r and the force of the spring 15r acts on the locking pins 16 via the abutment surfaces 15a of the shift fork 15. This means that the force of the spring 15r is received by the locking pins 16.

Due to the friction occurring between the abutment surfaces 15a of the shift fork 15 and the locking pins 16, the locking pins 16 can not move. The force of the springs, not shown, which seek to lock the locking pins 16 in their position releasing the shift fork 15 is not sufficient to overcome the static friction occurring between the abutment surfaces 15a of the shift fork 15 and the locking pins 16 due to the spring 15r. Thereby, the shift fork 15 is secured in its retracted position, even if the auxiliary latch 12 is pressed with the door open. The fact that the shift fork 15 is held in the retracted position, the shift fork 15 is not in contact with the locking elements 19, which in the case of contact to a release of

Guide the control rod 17 and an extension of the lower locking bar would. Furthermore, in this position, the tines of the shift fork 15 can not engage with the blocking elements 14. This has the consequence that the pivotability of the case 1 1 is maintained.

To b) Joint depression of trap and auxiliary trap with open

door

If the auxiliary latch 12 and the latch 1 1 manually pressed into the lock interior with open door, then the cams 12s of the auxiliary latch 12 out of contact with the locking pins 16. At the same time, the shift fork 15 together with the indented case 1 1 in the Lock interior displaced, so that the stop surfaces 15a of the shift fork 15 no longer rest against the locking pins 16. The locking pins 16 are displaced by locking pin springs, not shown, in their shift fork 15 releasing position.

Now, when the auxiliary latch 12 and the latch 1 1 is released, i. no longer be pressed, the following sequence is set. The auxiliary latch 12, the shift fork 15 and the bearing block 13, on which the case 1 1 is mounted, are each acted upon by an associated spring in the extension direction. In this common extension movement of auxiliary latch 12, shift fork 15 and bearing block 13 come first the cams 12s of the auxiliary latch 12 with the locking pins 16 into abutment, whereby the locking pins 16 in their the

Shift fork 15 blocking position to be shifted. In the course of the extension movement of the auxiliary latch 12, the shift fork 15 and the bearing block 13, the abutment surfaces 15 a of the shift fork 15 hit the locking pins 16, whereby the further extension movement of the shift fork 15 is stopped and whereby the shift fork 15 is held in a retracted position. Only the auxiliary latch 12 and the bearing block 13 with the case 1 1 mounted thereon can reach their fully extended positions.

Also in this case, the shift fork 15 is held in a retracted position and does not come into contact with the locking elements 19, which in the case of contact to a release of the control rod 17 and a

Extending the lower latch bar would result. Furthermore, in this position, the tines of the shift fork 15 are not engaged with the

Blocking elements 14. This has the consequence that the pivotability of the case 1 1 is maintained.

To c) Joint depression of trap and auxiliary trap with open

Door leaf with subsequent release of the trap when remaining

indented auxiliary trap

As already stated under b), the control cams 12s of the auxiliary latch 12 come out of contact with the locking pins 16 when the auxiliary latch 12 and also the latch 1 1 are pressed into the lock interior. Since the shift fork 15 are displaced together with the pressed-latch 1 1 in the lock interior, the abutment surfaces 15a of the shift fork 15 are no longer at the

Lock pins 16 on. The locking pins 16 are displaced by not shown locking pin springs in their shift fork 15 releasing position.

Now, if the case 1 1 is released, that is no longer pressed, while the auxiliary latch 12 remains in its pressed depressed into the castle interior position, the following sequence is: The shift fork 15 and the bearing block 13 on which the case 1 1 is mounted , are each acted upon by an associated spring in the extension direction. However, since the auxiliary latch remains in its depressed position, the cams 12s of the auxiliary latch 12 out of contact with the locking pins 16, ie the locking pins 16 remain in their position the shift fork 15 releasing position. Consequently, the shift fork 12 and the latch 1 1, acted upon by respective associated springs completely extend out of the lock. In this case, the prongs 15z of the shift fork 15 come into contact with the blocking elements 14 mounted on the bearing block 13.

By the engagement of the prongs 15z, the blocking elements 14 are pushed into the latching recesses 11d of the latch 11. As a result, the case 1 1 can no longer be pivoted. The case 1 1 now assumes its locking position, in which the case 1 1 completely out of the lock housing

is extended and is blocked in their pivoting.

When extending the shift fork 15 also come the switching edges 15s of the shift fork 15 in engagement with the locking elements 19. The locking elements 19 are displaced in the radial direction of the control rod 17 away, so that the locking elements 19 no longer engage in the groove 17r of the control rod 17 , As a result, the blocking of the locking bar 17 is released. The control rod 17 thereby moves upwards and the lower locking bar coupled to the control rod moves into its extended position locking the wing.

There are provided over the embodiment of the figures also modified versions in which a lower locking bar 7 is not present. This means that the door is locked exclusively in the area of the upper frame. The functions a), b) and c) are present in the same way. The locking and release of the locking bar only affects the upper locking bar, since a lower locking bar is not available. In another compared to the figures modified

Embodiment, a trap 1 1 can be used, not

pivotable about an axis perpendicular to the direction of extension of

Locking rod is formed, but is designed to be relatively movable relative to the locking bar only in the extension direction of the locking bar. In this embodiment, the above-described functions a), b) and c) are modified insofar exist that only the locking bar as in a), b) and c) is blocked or released. As far as the operation of the trap is concerned, actuating the trap means retracting or retracting the trap.

Structurally, in the embodiment with not

pivotable latch 1 1 simplifications. The components that relate to the pivotal mounting and the control of the pivoting, can

be omitted or simplified accordingly.
