The invention has for its object to provide a lock with a locking device with pivot latch, in which the interaction of the pivot latch with the frame-like strike plate is particularly trouble-free.

This object is achieved with the subject matter of patent claim 1.

The invention is directed to a lock for a movable, preferably pivotally mounted wing of a door or a window, with a wing side mountable lock mechanism with a locking device and an actuating device. The actuator may be a manually operable actuator, such as a rotary handle or a push rod act. However, it may also be provided that the actuating device is designed as a motor drive or otherwise powered by external energy actuator, for example as an electric motor or as a solenoid.

It is envisaged that the locking device has a pivotally mounted latch on a movably mounted bearing body or bearing block, which has an inlet slope and / or an outlet slope and is designed such that the latch can be brought into engagement with a locking position in a frame-mounted strike plate is and can be brought to form a release position out of engagement of the strike plate.

It is further provided that the locking device has a switching device which acts between the actuating device and the case for controlling the case, and that the case cooperates with the switching device such that the case in a non-pivotal, so rotationally rigid position and a pivotable, ie not rotationally rigid position can be brought, wherein the case is present in the locked position in the non-pivotable position. In the locking position, the latch is fixed on the bearing body unschwenkbar. This is feasible that the wing can not be opened by pulling or regurgitation. By the switching device, the case can be converted into a pivotable, so not torsionally rigid position. In this position, the case is pivotable with respect to the bearing body. The door can only be opened when the latch assumes the pivotable, not torsionally rigid position.

It is further provided that the locking device has a movable over the actuating device latch control member.

It is further provided that the switching device has a cooperating with the bolt control member switching element and a cooperating with the trap case blocking device. By the case blocking device, the case is held by its non-pivoting, rotationally rigid position. The switching element can serve to transfer the case from its non-pivoting, rotationally rigid position into its pivotable, non-torsionally rigid position, and vice versa. It is further provided that the locking device is designed as a locking bar device having at least one along the closing edge of the wing on the actuator for locking and unlocking and retractable locking bar, wherein the locking bar forms the bolt control member by the locking bar at its free end the switching element cooperates with the pivotally mounted case.

It is essential in the present invention that the latching blocking device has at least one blocking element movably mounted on the bearing body, which cooperates with the switching element to form a first relative position and a second relative position by lockingly engaging the blocking element in the first relative position in the recess of the latch Training the non-rotatable, non-pivotal position of the case and in the second relative position in the recess of the case does not engage or not locking engages to form the non-rotating, pivotal position of the case. This can be realized that the blocking element and the switching element cooperate such that in the first relative position, the blocking element is held by the switching element on the bearing body in the locked position, preferably immovably fixed. One end of the blocking element can in this case engage in the recess of the case, while the other end of the blocking element is held by the switching element. In the second relative position, the switching element is preferably distanced from the blocking element; ie the blocking element is no longer in this position Bearing body fixed in the locked position, but can be moved. By pivoting the case, the blocking element is then moved out of the recess of the case and moved in the bearing body. Preferably, the receptacle of the case and the attacking on the end of the blocking element corresponding spherical-shaped contours, so that when pivoting the case, the displacement of the blocking element in the bearing body is simplified.

It can further be provided that the switching element is designed as a shift fork, which has two prongs, which cooperate with a respective blocking element. This shift fork can be designed so that it engages around the bearing body from two opposite sides. The blocking elements are then preferably each offset by 180 ° in corresponding receptacles mounted on the bearing body. In the first relative position described above, a respective prong of the switching element engages one of the blocking elements and holds the blocking elements in their position fixing the trap.

It is advantageous that wedge-shaped flanks are formed on the shift fork in the region of the tines. If the shift fork is moved in the direction from the second relative position to the first relative position, the flanks are preferably used to displace the blocking elements in the direction of the case, so that the blocking elements engage in the recesses of the trap for locking the case.

It can further be provided that the at least one blocking element has a pin-shaped body, and that the recess is formed as a pin-shaped body receiving through hole. Of the pin-shaped body serves to guide the blocking element, which is movably guided in the through hole.

It can be provided that the at least one blocking element is mounted to be movable parallel to the axis of rotation of the latch and / or is aligned perpendicular to the direction of movement of the switching element.

The case may be formed as part of a lock mechanism and actuated by actuation of the lock mechanism, in particular by a nut or a lock cylinder, depending on the design of the lock in locking and / or unlocking. The operation of the lock mechanism can be done manually or via a motor drive.

Embodiments are particularly preferred which provide that the locking device has an auxiliary trapping device in the region of the trap. The auxiliary trapping device can be controllable via the striking plate or a part on the closing plate and cooperate with the locking control element and / or the latch such that only in the closed position of the wing the latch can be brought into its locking position and / or released. The auxiliary trap device ensures that the trap can assume its torsionally rigid, non-pivotable position only in the closed position of the wing.

It can be provided that the auxiliary trapping device has a spring-loaded probe with inlet slope and / or outlet slope. The button of the auxiliary latch device is used to detect whether the wing is in the open position or whether the wing rests against a door frame side strike plate.

It can be provided that the auxiliary trapping device has a sleeve-shaped body, in the interior of which the bolt control member and / or the locking bar and / or the switching element of the switching device and / or the latch bearing body and / or the latch at least partially engaging and / or relatively movable to the sleeve-shaped body is stored or are. By the sleeve-shaped body which surrounds said elements of the lock mechanism, a particularly space-saving design is possible.

It can be provided that between the switching element of the switching device and the auxiliary trapping device on a lock housing fixed bearing body movably supported switching element blocking element or blocking element is arranged, which is controllable via a control cam on the auxiliary trapping device such that the switching element blocking member in a first position is in abutment with the switching element to block the switching element against an extension movement, and that the switching element blocking member is in a second position out of abutment with the switching element. The auxiliary trap device interacts here with the control member. In the open position of the door, i. when the auxiliary latch is extended, the switching element blocking member projects into the movement range of the switching element. As a result, a movement of the switching element is prevented from the latch case. The trap remains in its pivotal, not torsionally rigid position when the auxiliary trap is extended. In the closed position of the wing, i. when retracted auxiliary latch, the movement of the switching element is no longer blocked by the switching element blocking member. The switching element can then act on the bearing body of the case and the lock housing fixed bearing body is spring-loaded in the sense of blocking the switching element is mounted.

It can be provided that between the bolt control member and a lock housing fixed bearing body, a movable latch-control member locking member or latching element is arranged, which is controlled by a control cam on the switching element of the switching device such that the bolt control member locking member engages in a first position in a locking member formed in the locking recess to block the bolt control member to the lock housing fixed bearing body against an extension and that the bolt control member-locking member is spring-loaded in a second position in the lock housing fixed bearing body in the sense of a locking of the bolt control member. When unlocking the bolt control member is displaced away by the actuator in the direction of the case. The bolt control member-locking member then engages in the latching recess of the bolt control member, thereby locking the bolt control member in a position spaced from the case. When locking the lock, the locking of the bolt control member is lifted in the common extension of the switching element and the case in the direction of the locking position. The switching element displaces the bolt control member locking member, whereupon the bolt control member is released. The bolt control member then moves spring loaded in its initial position and is ready for another unlocking operation. In advantageous embodiments, the switching element, the bearing body, the bolt control member and the bolt control member-locking member are configured so that the locking of the bolt control member is released only by the bolt control member locking member after the case has reached its locking position. In such embodiments of the lock, the control cam of the switching element comes only in entarretierenden Engaging the latch control member locking member simultaneously or after the latch is extended to its locked position.

It can be provided that the lock has a sleeve-shaped housing body, which is fixed wing mounted and in which the auxiliary trapping device, the bolt control member, the latch and preferably the switching device with the switching element and preferably the Fallenlagerkörper mounted axially displaceable and / or at least each partially received ,

It can be provided that in the sleeve-shaped housing body of the housing-fixed bearing body mounted axially supported and / or at least partially received. The bearing body may in this case be fastened by a screw or clip connection on the sleeve-shaped housing body.

In embodiments of the lock with locking bar can be provided that the at least one locking bar is formed as an upper locking bar, which is arranged in its locking position so that the arranged in the region of its upper end case cooperates in the closed position of the wing with the strike plate, the upper frame of the door or the window can be mounted.

It can be provided that the upper locking bar and the lower locking bar are coupled in opposite directions movably via a coupling gear.

It can be provided that the upper locking bar is acted upon by a spring in the locking direction 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 Bar is connected to the lower locking bar via a coupling mechanism which connects the two locking bars for a forced opposite movement. It can be provided here that the case is arranged on the ceiling-side end of the wing and cooperates with an upper strike plate and at the lower end of the wing only a lower locking bar is arranged. Preferred embodiments of the lock in this case have the previously described bolt control locking member. This means that the lock releases the bolt control member only from the locking position, at the same time or after the case is extended to its locking position. This avoids that the lower locking bar extends before reaching the closed position of the wing in their extended, the wing locking position.

An embodiment of the switching mechanism with a pivot latch, which is permanently acted upon by a spring element in the first pivot position; (Assembly accordingly Fig. 4d shown).

Fig. 1 shows a two-leaf door 1, which includes 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 operatively connected via parallel to the vertical longitudinal sides of the passive wing 2 locking bars 7 with a central lock 8, ie with an actuator of the lock 8. The lock 8 has a pusher 8d, which cooperates with a coupling mechanism, wherein the coupling mechanism converts a rotary movement of the pusher 8d into simultaneous pushing movements of the locking rods 7. The locking bars 7 is a upper latch bar and one lower latch bar. By depressing the pusher 8d, the locking bars 7 are moved in the direction of the lock, ie 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.

The Fig. 2 to 8 show the structure of the upper switching mechanism 6 in detail. The FIGS. 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 11 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

It is referred to the FIGS. 2 to 5 , The switching mechanism 6 has a latch 11, and a bearing block 13, on which the latch 11 is pivotally mounted on. 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 movably mounted in the housing of the switching mechanism 6 in the axial direction. In FIG. 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 11 and the bearing block 13

It is referred to FIG. 2 , The switching mechanism 6 has the latch 11. The latch 11 engages in the closed position of the door in a arranged on the door frame 4 strike plate 4s,

It is referred to the FIGS. 4a to 4c , The latch 11 is pivotally mounted on the bearing block 13. The latch 11 has a through hole 11d for receiving a journal 11z (FIG. Fig. 4d ) passing through a through hole 13d formed in a bearing block 13 ( Fig. 4b ) or is mounted in a differently designed pivot bearing bearing block side. The bearing block 13 engages with its upper end portion in a slot formed in the lower end portion of the slot 11 a recess ( Fig. 4d ). The bearing block 13 is by means of a return spring, not shown in the extension yet up, so acted upon by the actuator 8, applied.

It is referred to the FIGS. 5a to 5c , The latch 11 has in its lower end portion on further opposite recesses 11 r, engage in the spring-loaded locking pins 14 which cooperate with a shift fork 15 ( Fig. 5a ). The shift fork 15 is used to lock and unlock the case eleventh

Fig. 5b shows the latch 11 in the locked state in which the locking pins 14 in the latching recesses 11r engage and thus prevent rotation of the latch 11. In this position, the prongs of the shift fork 15 push the locking pins 14 into the latching recess 11r of the latch 11. As a result, the latch 11 can not be rotated. The locking pins 14 are mounted radially displaceably in the bearing block 13. The locking pins 14 cooperate with a device which moves the locking pins 14 outwardly when the locking pins 14 are disengaged from the tines of the shift fork 15. This device may be controlled by the pivoting movement of the latch 11. It can be provided that corresponding catch surfaces or abutment surfaces are formed on the latch 11 and on the locking pins 14. The locking pins are moved in this way outward when the tines of the shift fork 15 do not act on the Sperrstife 14. Additionally or alternatively, the locking pins can also be acted upon by associated springs radially outward.

Fig. 5c shows the latch 11 in the unlocked state by the case is in a rotated about its journal 11z position and the locking pins 14 are not engaged with the locking recesses 11r. The trap 11 is now rotatable. In this rotatable position, the shift fork 15 is moved with respect to the case 11 down. The locking pins 14 no longer engage in the locking receptacles 11r of the latch 11 when the shift fork 15 is shifted downwards. This means that the latch 11 can now be pivoted about the axis of the journal 11z.

The shift fork 15

It is referred to Figure 4c , The shift fork 15 is formed of a tube having at its upper end portion two opposing forks 15z with bevelled switching edges 15f has, which cooperate with the aforementioned locking pins 14. The forks 15z are guided in guide slots 13f of the bearing block 13.

It is referred to the Figures 3 and 8a and 8b , At the lower end portion of the shift fork 15, two opposing arms 15a are arranged, whose front faces directed towards the forks 15z form abutment surfaces 15a for locking pins 16, as will be described below. The shift fork 15 is connected by means of a return spring 15r (FIG. Fig. 3 ) in a starting position recoverable, in which the case 11 is locked.

The auxiliary trap 12

As Fig. 3 shows the auxiliary latch 12, the latch 11. The auxiliary latch 12 has a tubular body in which the shift fork 15 and the bearing block 13 is received with the case 11. The tubular body of the auxiliary latch 12 has a plurality of slot-shaped axially extending recesses. In the upper end section, the tubular body has a latch body with a slot-shaped recess for the passage of the latch 11. The tubular 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 tubular body of the auxiliary latch 12 is acted upon by means of a return spring, not shown in the figures in the extension direction upwards, ie away from the actuator 8.

The function of the auxiliary trap is described below: Reference is made to Fig. 2 The auxiliary latch 11 detects whether the door leaf is in the closed or open position. In the in Fig. 2 illustrated position is the auxiliary latch 12 on 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 in FIG FIG. 3 can be seen, 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 FIG. 3 the release position is shown in which the locking pins 16 do not protrude into the path of movement of the shift fork 15. In FIG. 14 the blocking position is shown: Here, the locking pin 14 can be seen, on which an arm 15a of the shift fork 15 abuts. 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 latch 11 is pivotable.

The shift rod 17

The shift rod 17 is in FIG. 7b shown alone. The switching rod is in operative connection with the actuating device of the lock 8 (FIG. Fig. 1 ). As Figure 7a shows, the shift rod 17 passes 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 11. 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

The Fig. 6a and 6b show a bearing element 18. The constructed of two half-shells bearing element 18 has first guide recesses 18 e, in each of which a spring-loaded with a spring not shown in the figures detent element 19 is guided. The latching element 19 cooperates with the circumferential latching groove 17r, which is formed on a shift rod 17 (see Fig. 7a and 7b ). The locking element 19 is formed by a formed in the lower portion of the shift fork 15 control cams 15s (see Fig. 4c ) controlled. 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 18 fz, in each of which a further above in Fig. 3 described, spring-loaded locking pin 16 is guided.

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

Fig. 9 shows the switching mechanism 6 with locked latch 11. The switching rod 17 connected to the upper locking bar 7 assumes its upper position.

Fig. 10 shows the switch latch 6 with unlocked latch 11. The connected to the upper latch rod 7 shift rod 17 assumes its lower position.

Fig. 11 shows the switching mechanism 6 with unlocked and tilted trap 11th

Fig. 12 shows the switching mechanism 6 with tilted and in the housing of the switching mechanism 6 retracting trap 11th

Fig. 13 shows the switching mechanism 6 with retracted latch 11 and extended auxiliary latch 12 and the

Fig. 14 shows the switching mechanism 6 with the latch 11 extended and the auxiliary latch 12 extended.

In the following, the operation of the switching mechanism 6 is based on the mentioned FIGS. 9 to 14 be explained. Here is in FIG. 9 the switch lock 6 shown with locked passive wing. FIG. 14 shows that Switch lock 6 with fully opened passive wing. In the Figures 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 with the passive wing 2 locked. The switching rod 17 connected to the upper locking bar assumes its upper position. The case 11 is fully extended and engages in a her assigned, not shown latch 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 11z and thus prevent rotation of the case 11. This position of the latch 11 on the shift fork 15 is in FIG. 5b shown. The latch 11 is rigid in this position, that is torsionally rigid and / or not pivotable, since the shift fork 15 holds the latch 11 via the locking pins 146 in its illustrated rotational position.

The intermediate position in FIG. 10

FIG. 10 shows the switching mechanism 6 after pressing the actuator of the lock 8. The operation can be done 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 switching rod 17 connected to the upper locking bar 7 is likewise retracted in the direction of the lap 8. In the illustrated embodiment, the shift rod 17 is as the upper Section of the locking bar 7 is formed. 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 latch 11 remains in its fully extended position. The fact that the shift fork 15 is retracted, the forks 15z are out of engagement with the locking pins 14. The locking pins 14 no longer engage in the locking recess 11r of the case 11 a. As a result, the blocking of the latch 11 is canceled. The latch 11 is not rigid in this position, ie it is pivotable because 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 11 out. The passive wing 2 is no longer locked in this position and can be opened by pressing. In the in FIG. 10 shown position, the auxiliary latch 12 is partially extended, the extension of the auxiliary latch 12 is effected by application of a spring, not shown, and the in FIG. 10 Not shown lock plate limited.

The intermediate position in FIG. 11

FIG. 11 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 compared to the in FIG. 10 position shown unchanged. Only the case 11 is pivoted, which is caused by striking the case 11 to the edge of the bolt receptacle of the door frame-side striker when pressing the passive wing 2. The trap 11 is then no longer rigid in this switching position, since the latch 11 assumes a pivoting position in which the locking pins 14 do not engage in the locking recesses of the latch 11r. In this pivotal position, the latch 11 remains pivotable, regardless of the position of the shift fork 15th

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 locking element 19 and the shift rod 17 are compared to those in the Figures 10 and 11 represented positions unchanged. In FIG. 12 is the case 11 on the door frame side lock plate and now no longer engages in the bolt receptacle of the strike plate. By the system of the case 11 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 opposite to in the Figures 10 and 11 Position shifted even further down. The shift of the shift fork 15 is effected in that the locking pins 14 mounted on the bearing block 13 rest on the upper sides of the switching prongs 15 of the shift fork 15 and causes a displacement of the bearing block 13 down and thus a shift of the shift fork 15 down. It should be noted that the shift fork 15 in the in FIG. 12 shown position, the locking pins 14 can not push into the locking receptacles of the case 11, as in pivoted case 11, the locking receptacles 11 are not aligned with the bearing 13 a of the locking pins 14. This means that the trap 11 in the in FIG. 12 shown position is pivotable and not fixable. The trap 11 is still in the position as in FIG. 11 in which the trap 11 is not detected by the switching tines 15z.

The intermediate position in FIG. 13

In contrast to FIG. 12 is the auxiliary trap 12 in FIG. 13 no longer on the strike plate and is fully driven up under the effect of spring acting on it. The displacement of the auxiliary latch 12 upward to its fully extended position causes the locking pins 16 mounted in the wing-fixed bearing member 18 are displaced by the control edge 12s of the auxiliary latch 12 so that the locking pins 16 project into the range of movement of the shift fork 15, because the locking pins 16 are still applied by the slope of the control edges 12s.

FIG. 13 shows the switching mechanism 6 thus in a further position during the opening of the passive wing 2. The positions of the locking element 19 and the shift rod 17 are compared to those in the Figures 10 , and 12 represented positions unchanged. The case 11 is also still in contact with the door frame-side strike plate, so that the position of the case 11, the bearing block 13 and the shift fork 15 with respect to the in FIG. 12 position shown are unchanged. Only the auxiliary latch 12 is no longer on the strike plate.

The unlocked open position / end position

FIG. 14 shows the switching mechanism 6 in its position with the passive wing 2. In this position, the case 11 is no longer on the door frame side lock plate and is fully extended and the case 11 is its non-rotating rigid pivotal position. The shift fork 15 is associated with a spring 15 r, which on the wing-fixed bearing element 18th is supported and the shift fork 15 is acted upon in the direction of the extended position of the associated latch 11. 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 11 is 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 protrude into the 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 the auxiliary latch 12 is extended further movement of the shift fork is prevented upwards and the shift fork 15 is held by the locking pins in a middle position. At the in FIG. 14 shown open position of the passive wing remains the position of the locking element 19 and the control rod 17 relative to the in the FIGS. 10 to 13 position shown 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.

In the following, the operations in the transfer of the switching mechanism 6 are to be explained from the open position of the passive wing 2 in the locked position of the passive wing 2.

Starting point is the in FIG. 14 shown position, which shows the switching mechanism 6 with the passive wing open. Here, both the auxiliary latch 12 and the bearing block 13 with the latch 11 mounted thereon are in their fully extended position. The shift fork 15 is closed by the locking pins 16 in Distance to the trap 11 held. The shift fork 15 is disengaged from the latch 11. This means that the latch 11 is tiltable. Further, the locking element 19 is located on the locking groove 17r of the control rod 17, whereby the control rod 17 is held in its retracted position. When closing the passive wing 2 the first case 11 comes into abutment against the strike plate ( Fig. 13 ). As a result, the first case 11 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 in Fig. 14 shown position with the difference that the case 11 is pivoted to the auxiliary case out. Upon further tightening of the passive wing 2, the bearing block 13 with the latch 11 mounted thereon is pushed into the switch lock 6. In the course of tightening the passive wing and the auxiliary latch 12 comes 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 that in the Figures 12 and 12a shown position with the difference that the case 11 is pivoted to the auxiliary case out. When retracting the auxiliary latch 12, the control cams 12s come out of contact with the locking pins 16 (see Fig. 12a ). The locking pins 16 are shifted back by springs, not shown, radially outward to its 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 is then urged spring urged toward the case 11. In the upward movement of the switching prongs 15z come to the locking pins 14 and urge the locking pins 16 in the locking receptacles 11d of the case 11. Thus, the case 11 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 11 in its fully extended positions. This locking position is in FIG. 9 shown.

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 in the radial direction outwardly from the locking groove 17r of the control rod 17 out. 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. However, the shift fork can only go up when the auxiliary case 11 is partially retracted by the strike plate in the switch lock 6 and is prevented by the strike plate on the extension.

The upper and lower locking bar 7 and 6 are coupled via a coupling mechanism of the lock 8, that is, via a coupling mechanism of the actuating device of the lock 8 with each other. This means that the lower locking bar 7 can only then extend into the base-side recess as soon as the locking element 19 no longer engages in the locking groove 17r 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 extend completely when the case 11 is extended in the door frame side recording.

Furthermore, 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 11 does not extend downwards 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 is acted upon by a spring in the locking direction 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 latch bar is connected to the lower rack bar via a dome gear connecting the two latch bars for forced mutual movement.

By controlling the case 11 of the lower locking bar by the upper switching mechanism 6 is achieved that the case 11, the lower locking bar with open passive wing 2 causes no damage to the bottom of a walk-through door 1 space. Rather, the lower locking bar is retracted despite pressed handle 8d of the passive wing 2, as in Fig. 13 shown and only leaves again when the case 11 is fully 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 acts on the latch 11 via a handle 8b or via a motorized actuating drive, not shown, only in the sense of unlocking the lock, i. only to move the latch 11 in the unlocking or at least free to turn the case 11 that they can go to the unlocked position. The locking of the lock takes place automatically automatically, i. the latch 11 is self-locking without the need for manual or motorized actuation of the actuator 8. In the case shown in the figures, the locking takes place automatically as soon as the wing is brought into the closed position and thereby an actuation of the auxiliary latch 12 and an actuation of the latch 11 by abutment 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 the sole condition for the expiration of the lock.

In FIG. 15 another embodiment of a lock is shown. This lock has, in accordance with the lock described above, a latch 11 mounted on a bearing body 13, a switching element 15 and an auxiliary latch device 12. The main difference to the castle FIGS. 1 to 12 is that the lock according to Fig. 15 a locking ring 20 for locking the bolt control member 17 and further comprises an actuator 19. The clamping ring 20 and the actuator 29 will be 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 catch 11. 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 auxiliary latch device 12 is supported at least in sections on the clamping ring 20. The clamping ring 20 and the auxiliary latch device 12 are acted upon by a helical compression spring 20r in the direction of the latch 11 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 trapping device 12 is actuated by the frame, preferably by a frame side mounted striking plate and thus the clamping ring 20 is displaced by the auxiliary trapping device 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 encompassed only by the clamping ring 20, wherein 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 bolt control member 17 is freely movable in this position by the clamping ring 20 without clamping.

If no external forces act on the auxiliary latch device 12, the auxiliary latch device 12 and the clamping ring 20 is acted upon by the force of the helical compression spring in the direction of the case. 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 the bolt control member 17. The bolt control member 17 is fixed by the clamping ring 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. When frame side acted auxiliary trapping device 12, as is the case with the door closed, the bolt control member 17 is free to move. When the door is open, when the auxiliary latch is extended, the extension of the bolt control member 17 is prevented to case out.

The actuator

The actuator 29 is inserted at the falling end of the bolt control member 17. The actuator 29 has its from the bolt control member 17th facing away from 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 bolt control member 17 is preferably more or less far beyond the adjustable variable. 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. Here, the height at which the head of the actuator 29 projects beyond the bolt control member 17, can be variably adjusted by appropriate screwing. 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 actuator 8 by a handle or a motor drive device, the bolt control member 17 is moved together with the attached actuator 29 away from the case 11 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 member 15 of the case 11, the latch 11 is transferred to its pivotal position, since the forks of the switching member 15 are disengaged from the blocking pins.

The fact that the actuator 29 can be used in variable depth in the bolt control member, can be adjusted, whether upon actuation of the actuator 8, the switching member 15 immediately or only after one certain actuating travel of the bolt control member 14 is taken. Whether the switching member 15 is taken immediately upon actuation of the actuator 8 from the bolt control member 17 or only in the course of the actuation path of the bolt control member 17 depends on how the lock is to be used.

When using the lock as an upper lock on a passive leaf of a double-leaf door can be provided that the lock with a Fallen / Riegelauswerferschloss the passive leaf acts together. In such use of the lock, it is important that the locking position of the latch 11 of the lock is only canceled after the ejector of the trap / Riegelauswerferschloss were 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 an upper lock on a single-leaf door, it is desirable that the Verrieglungsstellung the case 11, ie the non-pivoting of the latch 11, immediately upon actuation of the actuator 8 is released. In this case, the actuator 29 is inserted into the bolt control member 17 during assembly of the lock, that in the locking position of the lock between the head of the actuator 29 and the switching member 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.

As for the locking process, is in the in the Fig. 15 illustrated embodiment, that the case 11 cooperates with the auxiliary trapping device 12 and / or the bolt control member 17 such that the case 11 can be brought by a closing plate side actuation of the auxiliary trapping device 12 in its Verrieglungsstellung and / or freely switchable, without requiring a closing plate side actuation of the Trap 11 is required.

It is provided here that the release device is designed as a cooperating with the latch control element 17 and / or the latch 11 clamping device 20, and that the auxiliary latch device 12 directly cooperates with a release device of the latch control element 12 and / or the latch 11

In the previous FIGS. 2 to 14 illustrated embodiments is provided in contrast to the fact that the case 11 cooperates with the auxiliary trapping device 12 and / or the bolt control member 17 such that the latch 11 can be brought and / or released only in their locking position when a closing plate side actuation of the auxiliary trapping device 12 by retracting the Help trap device 12 and a closing plate side actuation of the latch 11 by pivoting the case 11 is done.

FIG. 16 relates to a modified embodiment in which the pivotal latch 11 via a spring 11f in the in Fig. 16 shown pivoting position is acted upon. 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 11 with the spring 11f.

It concerns the assembly, which for the preceding embodiment in Fig. 4d is shown. The remaining structure and functions of the modified embodiment corresponds to the embodiment of FIGS. 1 to 15 ,

The spring 11f 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 11f, the other leg of the spring engages in a receiving hole 11o in the case 11 a.

The only functional difference of this modified embodiment compared to the preceding embodiment is merely that the pivotal latch 11 is pivoted by the spring 11 f respectively in the first pivot position, so that in the open position of the door 1, the latch 11 occupies this first pivot position and so that too in the closed position of the door, the latch 11 occupies this first pivot position. This first pivotal position is also present when the door enters from the open position into the closed position and the case 11 comes with its inlet slope on the frame into abutment and the case is also drawn in locking bar extension direction in the door.

The second pivot position against the action of the spring 11f is obtained only temporarily, when the through the handle 8d (see Fig. 1 ) actuated locking bar 7, the pivoting of the latch 11 releases and during this operation of the handle 8 d, the case 11 is pivoted when opening the door 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. Immediately after reaching the closed position of the door drives the Swing latch and is returned by the spring 11f in the first pivot position.

This resetting of the latch 11 from the second pivot position to the first pivot position and the extension of the latch occurs each time the stop position between the latch and the frame is released. This is the case when the door has been moved from the closed position to the open position. However, this is the case when the stop position of the case and frame, which results in the closed position upon actuation of the door in the opening direction, is still canceled in the closed position and the door remains in the closed position. In this case, the latch 11 is pivoted back by the spring 11 f in the first pivot position.

The spring action of the case 11 with the door open has the consequence that in the open position of the door, the case 11 is always in the first pivot position. Here, the case 11 is in a position in which the pivotability of the case 11 can not be blocked by the shift fork 15. The case 11 can not be blocked by the shift fork here, because the shift fork 15 is held with the door open as in the previous embodiment by the locking pins 16 in their non-blocking case 11, in which they have been brought by the unlocking operation when opening the door is and the shift fork 15 is out of engagement with the latch 11. 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 11. This blocking takes place when the case 11 is in the first pivot position. The spring 11f acts on the latch 11, as already explained, in that the spring 11f engages the latch in the first position both in the closed position and in the open position of the door 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 latch 11 is blocked by the shift fork 15. This has the advantage that malfunctions are avoided, which arise when the spring is 11f in the closed position of the door after unlocking the shift fork 15 by actuation of the locking bar 7, the case 11 is brought into its second pivot position in the absence of spring. The second pivot position of the latch 11 adjusts itself by striking the latch on the frame when the door is acted upon in the closed position in the opening direction.

In the absence of the spring 11f, this second pivotal position of the latch 11 would remain, even if the door is subsequently not opened, but the latch 11 comes out of abutment of the frame and the door remains in the closed position. In the absence of the spring 11f, the latch 11 would engage its second pivotal position and into the frame-side receptacle. However, since the latch in the second pivot position can not be blocked by the indexing means, in this case the latch 11 would not be locked, i. she would be in an extended non-locking position. The case 11f according to the invention avoids such a malfunction.

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 latch 11 is secured. This means that by depressing the auxiliary latch 12 and / or the latch 11 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 latch 11 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 11 mounted thereon and the auxiliary latch 12 are in their positions extended from 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 latch 11 is freely pivotable because the shift fork 15 is in its retracted position and thus out of engagement with the latch 11, that is, the blocking elements 14 do not block the pivotability of the latch 11. 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 the case a) by the sole manual depression of the auxiliary latch 12 or in case b) by jointly pressing the latch 11 and auxiliary latch 12, the lock of the lock is not triggered. Only in case c) the lock of the lock is triggered, i. if, when the auxiliary latch 12 is pressed in and the latch 11 is pressed in at the same time, then the latch 11 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, then the control cams 12s of the auxiliary latch 12 out of contact with the locking pins 16. The springs, not shown, which act on the locking pins 16 in their shift fork 15 releasing position, the Lock 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. Characterized in 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 would lead in the case of contact to a release of the control rod 17 and to an extension of the lower locking bar. 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 latch 11 is maintained.

To b) Common impressions of trap and auxiliary trap with the door open

If the auxiliary latch 12 and also the latch 11 are pressed manually 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. At the same time, the shift fork is also activated 15 together with the depressed latch 11 with displaced into the lock interior, so that the stop surfaces 15a of the shift fork 15 no longer abut 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 also the latch 11 are 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 latch 11 is mounted, are each acted upon by an associated spring in the extension direction. In this common extension movement of the 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 are displaced in their the shift fork 15 blocking position. 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 latch 11 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 would lead to a release of the control rod 17 and to an extension of the lower locking bar. 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 latch 11 is maintained.

To c) Common impressions of trap and auxiliary trap with open door leaf with subsequent release of the trap with remaining depressed auxiliary trap

As already explained 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 11 are pressed into the lock interior. Since the shift fork 15 are displaced together with the indented case 11 in the lock interior, the abutment surfaces 15a of the shift fork 15 are no longer at the locking pins 16 at. The locking pins 16 are displaced by locking pin springs, not shown, in their shift fork 15 releasing position.

If now release the case 11, that is no longer pressed, while the auxiliary latch 12 remains in its actuated pressed into the castle interior position, the following sequence is: The shift fork 15 and the bearing block 13 on which the case 11 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 releasing the shift fork 15. Consequently, the shift fork 15 and the latch 11, urged by respective associated springs, can extend fully 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. The engagement of the prongs 15z causes the blocking elements 14 to be pushed into the detent recesses 11d of the catch 11. As a result, the case 11 can no longer be pivoted. The latch 11 now assumes its locking position, in which the latch 11 is fully extended out of the lock housing and is locked in its 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 bars 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 a further embodiment modified with respect to the figures, a latch 11 can be used which is not pivotable about an axis perpendicular to the extension direction of the locking bar, 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. Constructively arise in the embodiment with non-pivoting latch 11 simplifications. The components that the swiveling Storage and the control of the pivoting affect can be eliminated or simplified accordingly.
