Description

DESCRIPTION

Lock switch for bolt-rod

The invention relates to a lock for a leaf movably supported, preferably pivotably, of a door or a window. The lock has a lock mechanism that can be mounted on the side of the blade, with a bolt device and a drive device.

These types of locks are known. In known locks of this type, the bolt device has a bolt-bar device. The latch bar device has at least one removable and retractable bolt bar along the closing edge of the blade through the actuating device, which at its free end acts in conjunction with a bolt supported pivotably. In a locking position, the latch engages rigidly in a strike that can be mounted on the side of the frame and, in an unlocked position, acting in conjunction with the strike can be put out of engagement.

A lock of this type is known from EP1880072B1. The pivotally supported latch is controlled by a special support by actuating the latch bar. The special support is made in the free end of the bolt bar and has a shoulder and a free space to interact with it with the finger-shaped control tab of the bolt and block the pivoting capacity of the bolt.

A switch lock of a bolt-bar device is also known from document CH697988B1. This switch lock but does not have any latch supported in a pivoting manner. The bolt bar is requested by spring and in the closing position of the door engages in the strike. A clamping plate acts in conjunction with the bolt bar to maintain the bolt bar in the unlocked position against spring loading acting in the locked position and releasing it for movement to its locking position. The control of the clamping plate is made through a switching latch that acts in conjunction with the strike.

A lock according to the preamble of claim 1 is known from DE202012010248.

The object of the invention is to provide a lock with a bolt device with a pivoting latch, in which the joint action of the pivoting latch with the latch as a frame is especially fault-free

This objective is achieved with the object of claim 1.

The invention is directed to a lock for a movably supported sheet, preferably pivoting, of a door or a window, with a lock mechanism that can be mounted on the side of the sheet, with a bolt-on device and a drive device. The drive device can be a drive device that can be operated by hand, such as a rotary handle or a pressure rod. However, it can also be provided that the drive device is embodied as a motor drive or another type of actuator operated with external power, for example, as an electric motor or as a solenoid.

It is envisaged that the bolt device has a bolt supported pivotably in a supporting body or a support block supported in a mobile manner, which has an entrance bezel and / or an exit bevel and which is designed in such a way that the latch can be engaged with a strike that can be mounted on the side of the frame in a locked position and put out of engagement with the strike to form an unlocked position.

In addition, it is provided that the bolt device has a switching device acting between the actuating device and the bolt for controlling the bolt, and that the bolt acts in conjunction with the switching device, so that the latch can be removed. to a non-pivoting position, that is, rigid to rotation, and a pivoting position, ie, not rigid to rotation, the latch being in the non-pivoting position in the locked position. In the locked position, the latch is fixed non-pivotally on the support body. With this it can be realized that the sheet can not be produced by opening by pulling or by opening by pushing. By means of the switching device, the latch can be transferred to a pivoting position, that is to say not rigid to rotation. In this position, the latch can pivot with respect to the support body. The door leaf can only be opened when the latch is in the pivoting position, not rigid when turning.

In addition, it is provided that the bolt device has a bolt control member that can be moved on the actuator.

Furthermore, it is provided that the switching device has a switching element acting in conjunction with the bolt control member and a bolt locking device acting in conjunction with the bolt. Through the latch locking device, the latch is retained by its non-pivoting, rigid position at the turn. The switching element can serve to transfer the latch from its non-pivoting position, rigid to the rotation, to its pivoting position, not rigid to rotation, and vice versa.

In addition, it is provided that the bolt device is designed as a bolt-bar device, which has at least one removable and retractable bolt bar along the closing edge of the blade through the actuator for locking and unlocking , the bolt bar forming the bolt control member when the latch bar interacts at its free end through the switching element with the bolt supported in a pivoting manner.

In the present invention it is essential that the latch locking device has at least one blocking element movably supported on the support body, which acts in conjunction with the switching element forming a first relative position and a second relative position, in such a way that in the first relative position the locking element engages in the cavity of the locking latch, the rigid position forming the non-pivoting rotation of the latch, and in the second relative position does not engage in the cavity of the latch or engages without locking, forming the non-rigid position to the pivoting pivot of the latch. In this way, it is possible to realize that the blocking element and the switching element act together in such a way that in the first relative position the blocking element is preferably fixed immovably in the support body in the blocking position by the element of switching. One end of the locking element can engage here in the cavity of the latch, while the other end of the blocking element is held by the switching element. In the second relative position, the switching element is preferably at a distance from the blocking element; that is, in this position, the locking element is no longer fixed to the support body in the locked position, but can be moved. By pivoting the latch, the blocking element moves out of the latch cavity and moves within the support body. Preferably, the latch housing and the end of the locking element, which engages in the latch, have correspondingly shaped spherical shaped contours, so that during the pivoting of the bolt the displacement of the locking element within the body is easier. of support.

In addition, provision can be made for the switching element to be designed as a switching fork having two teeth acting together with respective locking elements. Said switching fork can be made in such a way as to wrap the support body from two opposite sides. Then, the locking elements are supported in corresponding housings in the support body, respectively being displaced 180 ° respectively. In the first relative position described above, respectively one tooth of the switching element attacks one of the locking elements and keeps the locking elements in their position that fixes the latch.

An advantage is that cuneiform flanks are made in the switching fork, in the region of the scissors. When the switching fork moves in the direction of the second position relative to the first relative position, the flanks preferably serve to move the locking elements in the direction towards the latch, so that the locking elements engage in the cavities of the latch for lock the latch.

In addition, it can be provided that the at least one locking element has a spike-shaped body, and that the cavity is made as a through hole which houses the spike-shaped body. The spigot-shaped body serves for guiding the blocking element which is movably guided in the through hole.

It can be provided that the at least one blocking element is supported movably parallel to the axis of rotation of the bolt and / or is oriented perpendicularly with respect to the direction of movement of the switching element.

The latch can be made as part of a lock mechanism and operated by actuating the lock mechanism, especially by a nut or a lock cylinder, in the direction of locking and / or unlocking, according to the embodiment of the lock. The actuation of the lock mechanism can be carried out manually or by means of a motor drive.

Particularly preferred embodiments are those in which it is provided that the bolt device has an auxiliary bolt device in the latch region. The auxiliary latching device can be controlled through the strike or a piece located on the side of the strike and act in conjunction with the bolt control member and / or the bolt in such a way that only in the closing position of the bolt. sheet, the latch can be put in its locked position and / or released for extraction. The auxiliary latch device ensures that, only in the closing position of the blade, the bolt can assume its rigid position at the non-pivoting rotation.

It can be provided that the auxiliary latch device has a spring-loaded feeler with an input bezel and / or an output bevel. The feeler of the auxiliary latch device serves to detect if the leaf is in the open position or if the leaf is supported by a strike on the side of the door frame.

It can be provided that the auxiliary latch device is supported displaceably with respect to the latch support body.

It can be provided that the auxiliary latching device has a body in the form of a sheath, in whose internal space the bolt control member and / or the latch bar and / or the switching element of the switching device are mounted or supported. / or the latch support body and / or the latch engaging at least in part and / or relatively movably with respect to the pod-shaped body. Thanks to the sheath-like body, which surrounds the aforementioned elements of the lock mechanism, a constructive form with a particular saving of space is possible.

It can be provided that between the switching element of the switching device and the auxiliary latching device there is arranged a blocking element of switching element or locking element, supported movably in a support body fixed to the lock box, that by means of a control cam on the auxiliary latching device is controllable in such a way that the switching element blocking member, in a first position, abuts the switching element to block the switching element against a movement and that the switching element blocking member, in a second position, does not abut the switching element. The auxiliary latch device acts in conjunction with the control member. In the open position of the door, that is to say, with the auxiliary latch removed, the switching element blocking element protrudes into the movement area of the switching element. In this way the movement of the switching element towards the lock latch is prevented. Therefore, a movement of the switching element towards the bolt latch is avoided. When the auxiliary latch is removed, the latch is kept in its pivoting position not rigid to the turn. In the closed position of the leaf, ie the auxiliary latch being retracted, the movement of the switching element is no longer blocked by the switching element blocking member. Then, the switching element can act on the latch support body and the fixed support bodies on the lock housing are supported, spring-loaded, in the direction of a blocking of the switching element.

It can be provided that between the bolt control member and a support body fixed to the lock box there is disposed a retaining member of a movable bolt control member or holding element that by a control cam on the switching element. The switching device is controlled in such a way that the latch control member retains, in a first position, a recess in the latch control member in order to lock the bolt control element against the latch. removal in the support body fixed to the lock box, and that, in a second position, the latch control member retaining member is supported in a spring-loaded manner within the support body fixed to the lock box, in the sense of a retention of the bolt control member. During the unlocking process, the bolt control member is moved by the actuating device in the direction opposite to the bolt. Then, the bolt control member retaining member engages in the recess of the latch control member retaining the bolt control member at a position located at a distance from the bolt. During locking of the lock, the retention of the bolt control member is canceled during the joint removal of the switching element and of the bolt in the direction towards the locking position. During this, the switching element moves the bolt control member holding member, after which the bolt control member is released. Then, the bolt control member moves in a spring-loaded manner to its starting position and is again ready for a new unlocking process. In advantageous embodiments, the switching element, the support body, the bolt control member and the latch control member are designed in such a way that the retention of the bolt control element is only canceled by the latch control member retaining member, after the latch has reached its locked position. In this type of embodiments of the lock, the control cam of the switching element only engages with the latch control member retaining the latch, canceling the latch at the same time or after the bolt has been removed. to its blocking position.

It can be provided that the lock has a case body in the form of a sleeve, which can be fixedly mounted to the leaf and on which are supported in an axially slidable manner and / or housed at least in sections by the auxiliary latching device, bolt control member, bolt and preferably the switching device with the switching element and preferably the bolt support body.

It can be provided that the supporting body fixed to the housing is supported axially in support and / or housed in sections of the case body in the form of a sleeve. The support body can be fixed to the box body in the form of a bushing by means of a screwed connection or clips.

In embodiments of the latch bar lock, it can be provided that the at least one bolt bar is designed as an upper latch bar which, in its locking position, is arranged in such a way that, in the closing position of the wing , the latch arranged in the area of its upper end acts together with the strike that can be mounted on the upper frame of the door or window.

It can be provided that the at least one bolt bar is made as a lower bolt bar which, in its locking position, is arranged in such a way that, in the closing position of the blade, the latch arranged in the area of its end acts in conjunction with a strike that can be mounted on the frame located on the bottom side of the door or window.

It can be provided that the upper bolt bar and the lower bolt bar are coupled together through a coupling gear and can move in opposite directions.

It can be provided that the upper bolt bar is loaded through a spring in the locking direction and that the auxiliary bolt acts in conjunction with the upper bolt bar, that the upper bolt bar is held in its unlocked position while the closing position of the blade has not been reached and the upper bolt bar is connected to the lower bolt bar by means of a coupling gear that joins the two bolt rods for a compulsorily opposing movement. It can be provided that the bolt is arranged at the end of the blade that is located on the side of the roof and acts in conjunction with an upper strike and that at the lower end of the blade only a lower bolt bar is disposed. Preferable embodiments of the lock have here the bolt control retention member that has been previously described. This means that the lock releases the bolt control member from the latching position only at the same time or after the bolt has been removed to its locking position. In this way, the lower bolt bar is prevented from being pulled out to its extracted position which locks the blade, before reaching the closing position of the blade.

Figure 1 shows a two-leaf door 1 comprising a passive sheet 2 and an active sheet 3 which are arranged in a hinged door frame 4.

The passive leaf 2 can be immobilized in the door frame 4 by means of an upper and lower switching lock 6 which is arranged on the upper front side or on the lower front side. The switching locks 6 are actively connected to a central lock 8, that is to say with the lock actuation device 8, by means of lock bars 7 arranged parallel to the vertical longitudinal sides of the passive leaf 2. The lock 8 presents a push-button 8d acting in conjunction with a coupling gear, the coupling gear transforming a rotary movement of the push-button 8d into simultaneous pushing movements of the bolt-bars 7. The bolt-bars 7 are an upper bolt-bar and a rod of lower bolt. By depressing the button 8d, the bolt bars 7 move in the direction towards the lock, that is to say in the direction towards the actuating device of the lock 8, and as described below, the switching locks 6 are unlocked. , the upper bolt bar 7 moves down and the lower bolt bar 7 moves up.

The active leaf 3 has a lock 9 with a button 9d, the lock 9 also having a lock bolt and a pin. The lock latch and the pin are made and arranged in such a way that they engage in a strike arranged in the passive leaf 2.

Figures 2 to 8 show in detail the structure of the upper switching lock 6. Figures 9 to 14 show in detail the functions and the working mode of the switching lock 6. The "up" and "down" position assignments chosen in the following description in relation to these figures correspond to the mounting position of the upper switching lock 6. For the lower switching lock 6, these position assignments have to be exchanged.

Figure 2 shows the upper section of the switching lock 6, engaging the bolt 11, in the switching position shown, in a housing in the strike 4s. In this way, the passive sheet 2 is fixed to the door frame 4.

The components of the switching lock

Reference is made to FIGS. 2 to 5. The switching lock 6 has a latch 11 and a support stand 13 on which the latch 11 is pivotably supported. The switch lock 6 also has an auxiliary latch 12 and a fork 15. The support stand 13, the auxiliary latch 12 and the switching fork 15 are supported movably in the axial direction inside the box of the lock box 6. In figure 2 the switching bar can be seen 17. The switching bar 17 is connected to the bolt bar 7 and actively connected to the drive device 8.

The latch 11 and the support stand 13

Reference is made to FIG. 2. The switching lock 6 has the latch 11. In the closed position of the door, the latch 11 engages in a strike 4s arranged in the door frame 4.

Refer to Figures 4a to 4c. The latch 11 is pivotally supported on the support stand 13. The latch 11 has a through hole 11d for receiving a support pivot 11z (FIG. 4d) passing through a through hole 13d made in the base stand. support 13 (figure 4b) or that is supported on a rotating support made in another way on the side of the support stand. The support stand 13 meshes with its upper end section in a slit-like cavity made in the lower end section of the latch 11 (Figure 4d). The support stand 13 is loaded by means of a return spring, not shown, in the upward direction of withdrawal, that is to say in the direction opposite to the actuation device 8.

Refer to Figures 5a to 5c. The latch 11 has, in its lower end section, also opposing retention cavities 11r into which muffled blocking pins 14 engage in conjunction with a switching fork 15 (FIG. 5a). The switching fork 15 serves to lock and unlock the latch 11.

Figure 5b shows the latch 11 in the locking state, in which the locking pins 14 mesh in the retention cavities 11r preventing a rotation of the latch 11. In this position, the teeth of the switching fork 15 push the pins blocking 14 to latch retention housing 11r 11. In this manner, latch 11 can not be rotated. The locking pins 14 are supported in a radially slidable manner on the support stand 13. The locking pins 14 act in conjunction with a device that moves the locking pins 14 outwards, when the locking pins 14 are outside the engagement. of the teeth of the switching fork 15. This device can be controlled by the pivoting movement of the latch 11. It can be provided that corresponding trailing surfaces or abutment surfaces are provided on the latch 11 and the locking pins 14. In this way, the locking pins move outwards, when the teeth of the switching fork 15 do not act on the locking pins 14. Additionally or alternatively, the locking pins can also be loaded radially outwardly by assigned springs.

Figure 5c shows the latch 11 in the unlocked state, so that the latch is in a position rotated about its support pivot 11z and the locking pins 14 are not in engagement with the retention cavities 11r. Now, the latch 11 can be rotated. In this rotary position, the switching fork 15 is displaced downwards with respect to the latch 11. When the switching fork 15 is displaced downwards, the locking pins 14 and do not engage in the retention cavities 11r of the latch 11. means that, now, the latch 11 can pivot about the axis of the support pivot 11z.

The switching fork 15

Refer to figure 4c. The switching fork 15 is formed by a tube which in its upper end section has two opposed fork teeth 15z with bevelled switching flanks 15f which act in conjunction with the locking pins 14 mentioned above. The fork teeth 15z are guided in guide slots 13f of the support stand 13.

Refer to Figures 3 and 8a and 8b. In the lower end section of the switching fork 15, two opposite arms 15a are arranged, the front surfaces of which facing the fork teeth 15z form stop surfaces 15a for locking pins 16 as described below. The switching fork 15 can be retracted, by means of a return spring 15r (FIG. 3), to a starting position in which the latch 11 is locked.

The auxiliary latch 12

As shown in Figure 3, the auxiliary latch 12 surrounds the latch 11. The auxiliary latch 12 has a tubular body in which the switching fork 15 and the support stand 13 are housed with the latch 11. The tubular body of the auxiliary latch 12 has several slit-shaped cavities that extend axially. In the upper end section, the tubular body has a latch body with a slit-shaped cavity for the passage of the latch 11. The tubular body of the auxiliary latch 12 is made in several pieces. It consists of an upper section 12o and a lower section 12u.

To facilitate assembly, the lower section 12u of the auxiliary latch 12 is composed of two half-shells. The tubular composite body of the auxiliary latch 12 is requested by means of a return spring, not shown in the figures, in the upward direction of extraction, that is to say in the direction opposite to the actuating device 8. The function is described below. of the auxiliary latch: reference is made to FIG. 2: the auxiliary latch 11 detects whether the door leaf is in the closed or open position. In the position shown in FIG. 2, the auxiliary latch 12 is in contact with the strike. In this position, the auxiliary latch 12 is partly retracted into the switch lock 6 and the strike 4s prevents its removal to its fully extracted position.

The auxiliary latch 12 also serves for blocking and releasing the switching fork 15. As can be seen in FIG. 3, the auxiliary latch 12 has a control cam 12s in its lower section, which serves for the displacement of spikes of blocking 16. The locking pins 16 are controlled by the control cams 12s made in the lower section of the auxiliary latch 12 in slit-shaped cavities. The control cams 12s have two linear sections of different height, aligned with the longitudinal axis of the auxiliary latch 12, which are connected by an oblique extension switching section. The locking pins can be displaced by the control cams 12s of the auxiliary latch, in such a way that the locking pins 16 enter the path of movement of the switching fork 15 opposing a movement of the switching fork 15 upwards. . The release position in which the locking pins 16 do not enter the path of movement of the switching fork 15 is shown in FIG. 3. The locking position is shown in FIG. 14: the spike can be seen here. blocking 14, with which an arm 15a of the switching fork 15 is in contact. By the fact that the arm 15a of the switching fork 15 is in contact with the locking pin 16, the fork movement is prevented. of switching 15, here upwards. This means that in this position the latch 11 can pivot.

The switching bar 17

The switching bar 17 is represented alone in FIG. 7b. The switching bar is in active connection with the actuating device of the lock 8 (FIG. 1). As shown in Figure 7a, the switching bar 17 passes inside the switching fork 15. The upper end section of the switching bar 17 has a cavity 17a in which a transverse pin is inserted (Figure 7b). Said transverse pin acts in conjunction with the switching fork 15. During the retraction of the switching rod 17 the switching fork 15 is driven, so that the switching fork 15 moves in the opposite direction to the latch 11. The switching has a circumferential retaining groove 17r. In this retention slot can enter retaining elements 19 (see Figures 7a and 7b) that prevent a movement of the switch bar 17 upwards. The retaining elements are described in detail below.

The support element 18

Figures 6a and 6b show a support element 18. The support element 18 formed by two half-shells has first guide cavities 18e in which a retention element 19 cushioned with a spring not shown in detail in the figures is guided. The retaining element 19 acts in conjunction with the circumferential retaining groove 17r which is made in a switching bar 17 (see FIGS. 7a and 7b). The retaining element 19 is controlled by a control cam 15s made in the lower section of the switching fork 15 (see FIG. 4c). The control cams 15s have two linear sections aligned with the longitudinal axis of the switching fork 12, which are connected by an obliquely extending switching section.

The supporting element 18 also has second guide cavities 18fz, in which a damped locking pin 16, previously described in FIG. 3, is guided.

Figures 9 to 14 show different operating states of the switching lock 6.

Figure 9 shows the switching lock 6 with the latch 11 blocked. The switching bar 17 attached to the upper latch bar 7 assumes its upper position.

Figure 10 shows the switching lock 6 with the latch 11 unlocked. The switching bar 17 attached to the upper latch bar 7 assumes its lower position.

Figure 11 shows the switching lock 6 with the latch 11 unlocked and tilted.

Figure 12 shows the switching lock 6 with the bolt 11 tilting retracted to the housing of the switching lock 6.

Figure 13 shows the switching lock 6 with the latch 11 retracted and the auxiliary latch 12 removed and figure 14 shows the switching lock 6 with the latch 11 removed and the auxiliary latch 12 removed.

Next, the mode of operation of the switching lock 6 is described with the help of the aforementioned figures 9 to 14. In FIG. 9, the switching lock 6 is shown, the passive leaf being blocked. Figure 14 shows the switching lock 6 with the passive sheet fully open. In figures 10, 11, 12 and 13, the switching lock 6 is shown in different stages during the opening of the passive sheet 2.

The lock position locked in figure 9 / end of stroke position

Figure 9 shows the switching lock 6 with the passive sheet 2 locked. The switching bar 17 attached to the upper bolt bar assumes its upper position. The latch 11 is completely removed and engages in a bolt housing not shown, assigned, of the strike in the door frame. The auxiliary latch 12 is only partially extracted. The complete removal of the auxiliary latch 12 is prevented by a striker not shown, arranged in the door frame. In addition, the switching fork 15 is in its upper position, the fork teeth 15z forcing the locking pins 14 to the retaining pockets 11z preventing rotation of the latch 11. This position of the latch 11 in the switching fork 15 is shown in figure 5b. In this position, the latch 11 is rigid, that is to say rigid to rotation and / or non-pivoting, since the switching fork 15 holds the latch 11 in its rotated position shown, through the locking pins 146. The intermediate position in figure 10

Figure 10 shows the switching lock 6 after the actuation of the lock actuation device 8. The actuation can be carried out manually by means of a button 8d. But it is also possible that the drive device is driven by motor. When the lock 8 is actuated, the bolt bar 7 moves in the direction towards the lock 8. During this, the switch bar 17 joined to the upper bolt bar 7 also retracts in the direction towards the lock 8. In the example of represented embodiment, the switching bar 17 is made as the upper section of the bolt bar 7. During the retraction of the switching bar 17 in the direction towards the lock 8, the switching fork 15 is also moved by the switching bar 17. The latch 11 remains in its fully extracted position. Due to the fact that the switching fork 15 is retracted, the fork teeth 15z are out of engagement with the locking pins 14. Now, the locking pins 14 no longer engage in the recess 11r of the latch 11. In this way, the locking of the latch 11 is canceled. In this position, the latch 11 is not rigid, that is to say that it can pivot, since the switching fork 15 is at a distance, that is to say, out of the meshing of the pins blocking 14.

In the retracted state of the switching bar 17, the retaining element 19 supported within the support element 18 engages in the recess 17r of the switching rod 17. The retaining element 19 keeps the switching bar 17 in its place. position retracted into or in the support member 18 fixed to the blade and prevents movement of the switching rod 17 towards the bolt 11. In this position, the passive blade 2 is no longer locked and can be opened by pushing. In the position shown in figure 10, the auxiliary latch 12 is partially extracted, the extraction of the auxiliary latch 12 is limited by the solicitation by a spring (not shown) and by the strike (not shown in figure 10).

The intermediate position in figure 11

Figure 11 shows the switching lock 6 during the opening of the passive sheet 2. The positions of the auxiliary latch 12, of the switching fork 15, of the retaining element 19 and of the switching bar 17 are unchanged with respect to the Only the latch 11 is pivoted, which occurs when the latch 11 abuts the edge of the latch housing of the striker located on the side of the door frame when the passive sheet 2 is opened by pushing. In this switching position, the latch 11 is no longer rigid, since the latch 11 assumes a pivoted position in which the locking pins 14 do not engage in the latching recesses 11r of the bolt. In this pivoted position, the latch 11 can still pivot, independently of the position of the switching fork 15.

The intermediate position in figure 12

Figure 12 shows the switching lock 6 in another position during the opening of the passive sheet 2. The positions of the auxiliary latch 12, of the retaining element 19 and of the switching bar 17 are unchanged with respect to the positions shown in FIGS. Figures 10 and 11. In Figure 12, the latch 11 is in contact with the strike located on the side of the door frame and now no longer engages in the lock housing of the strike. Due to the contact of the latch 11 with the strike, the support stand 13 with the latch supported therein is offset against the action of the spring 13r downwards in the direction towards the actuating device 8. The switching fork 15 is still displaced. further downwards with respect to the position shown in FIGS. 10 and 11. The displacement of the switching fork 15 is carried out in such a way that the locking pins 14 supported on the support stand 13 are in contact on the upper sides of the stand. the switching teeth 15 of the switching fork 15 causing a displacement of the support stand 13 downwards and therefore a displacement of the switching fork 15 downwards. It should be borne in mind that, in the position shown in FIG. 12, the switching fork 15 can not force the locking pins 14 into the retention cavities of the latch 11, since, with the latch 11 being pivoted, the retention cavities 11 are not aligned with the support 13a of the locking pins 14. This means that, in the position shown in FIG. 12, the latch 11 is pivoting and can not be fixed. In addition, the latch 11 is in the position as in FIG. 11, in which the latch is not immobilized by the switching teeth 15z.

The intermediate position in figure 13

Unlike Figure 12, in Figure 13, the auxiliary latch 12 is no longer in contact with the strike and has moved completely upwards under the action of the spring requesting it. The displacement of the auxiliary latch 12 upwards to its fully extracted position causes the locking pins 16 supported on the support element 18 fixed to the blade to be slid on the control edge 12s of the auxiliary latch 12, so that the pins of the latch blocking 16 enters the movement area of the switching fork 15, since the locking pins 16 are still required by the bevel of the control edges 12s.

Therefore, FIG. 13 shows the switching lock 6 in another position during the opening of the passive sheet 2. The positions of the retaining element 19 and of the switching bar 17 are unchanged with respect to the positions shown in FIGS. and 12. The latch 11 is also still in contact with the strike on the side of the door frame, so that the position of the latch 11, the support stand 13 and the switching fork 15 are unaltered with respect to the position shown in figure 12. Only the auxiliary latch 12 is no longer in contact with the strike.

The open position unlocked / end position

Fig. 14 shows the switching lock 6 in its position with the passive sheet 2 open. In this position, the latch 11 is also not in contact with the striker located on the side of the door frame and is completely removed and the latch 11 it is in its non-rigid position when turning, pivoting. A spring 15r is assigned to the switching fork 15 which is supported on the support element 18 fixed to the leaf and which requests the switching fork 15 in the direction towards the position extracted from the assigned latch 11. A spring 13r is assigned to the support stand 13, which is also supported on the support stand 18 fixed to the leaf and which requests the support stand 13 in the direction of the position extracted from the assigned latch 11. Under the action of the spring 13r not shown, the support stand 13 is forced, together with the latch supported therein, into its fully extracted position. The switching fork 15 is forced upwards by the action of the spring 15r. Since the locking pins 16 enter the movement area of the switching fork 15, the removal of the switching fork 15 is limited upwards. The locking pins 16 are in contact with the stop surfaces 15a of the fork of the fork. switching 15, so that, with the auxiliary latch 12 removed, the switching fork is prevented from moving upwards and the switching fork 15 is maintained in a central position by the locking pins. In the open position of the passive sheet, shown in FIG. 14, the position of the retaining element 19 and of the control rod 17 remains unchanged with respect to the position shown in FIGS. 10 to 13. The retaining element 19 follows being in contact with the retaining slot 17r of the control rod, whereby the control rod is kept in its retracted position.

Next, the processes during the transfer of the switching lock 6 from the open position of passive sheet 2 to the locked position of the passive sheet 2 are explained.

Starting point is the position represented in figure 14 which has the switching lock 6 with the passive leaf open. In this, both the auxiliary latch 12 and the support stand 13 with the latch 11 supported therein are in their fully extracted position. The switching fork 15 is kept at a distance from the latch 11 by the locking pins 16. The switching fork 15 is out of engagement with the latch 11. This means that the latch 11 can be tilted. In addition, the retaining element 19 is in contact with the retaining groove 17r of the switching bar 17, whereby the switching bar 17 is kept in its retracted position. During the closing of passive sheet 2, first, the latch 11 makes a stop with the strike (figure 13). In this way, first, the latch 11 is pivoted. The positions of the switching fork 15, the support stand 13, the auxiliary latch 12 and the commutator bar 17 remain unchanged. This position of the switching lock 6 corresponds to the position shown in FIG. 14, with the difference that the latch 11 is pivoted towards the auxiliary latch. By continuing to close the passive sheet 2 by pulling it, the support stand 13 with the latch 11 supported therein is slid into the switching lock 6. During the next course of the tension closing of the passive sheet, also the The auxiliary latch 12 abuts the strike (FIG. 12) and is inserted by sliding, together with the support stand 13 and the latch, into the switching lock 6. This position of the switching lock 6 corresponds to the position shown in FIGS. 12 and 12a with the difference that the latch 11 is pivoted towards the auxiliary latch. During the retraction of 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 displaced radially outwards, backwards, to their starting position, by springs not shown. This means that when the auxiliary latch 12 is retracted, the locking pins 16 are no longer in contact with the contact surfaces 15a of the switching fork 15 and the movement of the switching fork 15 upwards is no longer impeded. Then, the switching fork is forced towards the latch 11 by spring loading. During the upward movement, the switching teeth 15z reach the retaining pins 14 and force the locking pins 16 into the retention cavities 11d of the latch 11. In this way, the latch 11 is fixed with respect to the latch trestle. 13, meaning that it can no longer be pivoted.

As soon as the passive leaf 2 has reached its closing position, the bolt is no longer in contact with the strike. By means of a spring, the control fork 15 or the support stand 13 with the latch 11 fixed thereto are transferred to their completely extracted positions. This blocking position is shown in Figure 9.

During the movement of the control fork 15 to its extracted position, the control cam 15s comes into contact with the retaining element 19. In this way, the retaining element 19 is pushed out of the retaining slot 17r of the control bar 17. Then, the control bar 17 and the bolt bar 7 coupled to the control rod 17 are no longer fixed by the retaining element 19. Then, the bolt bar 7 can also be moved upwards.

What is essential in the switching lock 6 of the present invention is that the switching bar 27 and therefore the lock bar 7 coupled to it alone are not fixed by the retaining element 19, when the switching fork has moved towards above. But the switching fork can only move upwards when the latch 11 is partially retracted to the switch lock 6 by the strike and the strike prevents its removal.

The upper and lower bolt bars 7 and 6 are coupled to each other via a lock coupling gear 8, ie, through the coupling gear of the lock operating device 8. This means that the bar The lower bolt 7 can only be removed to the cavity located on the bottom side, when the retaining element 19 no longer meshes in the retaining groove 17r of the bolt bar 12 and therefore has released the control rod. As shown above, the retaining element 19 is moved by the control cam 15s of the switching fork 15, so that the switching fork can be completely removed, when the bolt 11 has been removed to the housing located on the side of the door frame. Furthermore, in the case of the lower bolt bar, a compensation of the gravitational force of the components is provided by spring-loaded vertically upwards, so that, without solicitation by the bolt-bar, the latch 11 is not withdrawn downwards. only in a controlled manner by the force of gravity. The extraction path of the auxiliary latch 12 is basically already limited by the stop.

In a particularly preferred variant of the illustrated embodiment, it is provided that the upper bolt bar is urged through a spring in the locking direction and that the auxiliary bolt acts in conjunction with the upper bolt bar in such a way that The upper bolt bar is held in its unlocked position until the closing position of the blade has been reached and the upper bolt bar is attached to the lower bolt bar through a coupling gear joining the two rods of bolt for a forced mutual movement.

By controlling the latch 11 of the lower bolt bar by the upper switching lock 6 it is achieved that, with the passive leaf 2 open, the bolt 11 of the lower bolt bar does not cause damage to the floor of a room at the which can be accessed through the door 1. Rather, in spite of pressing the button 8d of the passive sheet 2, the lower bolt bar is retracted, as shown in FIG. 13, and it is only removed again when the the passive sheet 2 is closed, the latch 11 has been completely removed to the inside of the strike 4s in the housing located in the door frame.

In preferred exemplary embodiments, for example in the exemplary embodiment shown in the figures, it is provided that the actuating device 8 acts on the latch 11 via a handle 8b or a motor drive (not shown), only in the sense of unlocking the lock, that is, only to move the latch 11 to the unlocking position or at least to release the latch 11 in such a way that it can be moved to the unlocking position. The locking of the lock is carried out automatically, that is to say that the latch 11 is self-locking, without requiring a hand drive or a motor drive of the actuator 8. In the case shown in the figures, the locking is performed automatically as soon as the leaf has been brought to the closed position and during this, an actuation of the auxiliary latch 12 and a drive of the latch 11 has been produced by abutting the frame and / or the strike. In the embodiment shown, the two conditions mentioned for the blocking sequence are required. In modified embodiments as also described in connection with the exemplary embodiments, the actuation of the auxiliary latch can also be provided as a single condition for the blocking sequence. In Figure 15 another embodiment of a lock is shown. Coinciding with the lock described above, this lock has a latch 11 supported pivotally on a support body 13, a switching element 15 and an auxiliary latching device 12. The essential difference with respect to the lock of figures 1 to 12 is that the lock according to FIG. 15 has a clamping ring 20 for retaining the bolt control member 17 and also an adjusting member 19. The clamping ring 20 and the adjusting member 29 are described below.

The tightening ring

The clamping ring 20 is slidably supported in the lower area, opposite the latch 11, of the casing body 6g in the form of a bushing. The clamping ring 20 has substantially the shape of a hollow cylinder. The clamping ring 20 has a cantilever with which the clamping ring 20 is supported in a secured manner against rotation in a groove 6gs inside the housing body 6g.

Above the clamping ring 12, the auxiliary latch device 12 is slidably disposed within the housing body 6g. The auxiliary latch device 12 is supported at least by sections in the clamping ring 20. The clamping ring 20 and the auxiliary latch device 12 are urged by a helical compression spring 20r in the direction towards the latch 11. The spring 20r helical compression is supported on a 20rs support ring. The support ring 20rs has three overhangs with which the support ring 20rs can be inserted into the housing body 6g fixedly to the housing. For this, the housing body 6g has three corresponding insert housings 6ge for the support ring 20rs.

The bolt control member 17 passes through the clamping ring 20 from below passing coaxially through the helical spring 20r and the support ring 20rs. The auxiliary latch device 12 rests on the upper side of the clamping ring 20.

In the closing position of the door, the auxiliary latch device 12 is driven by the frame, preferably by a strike fitted on the side of the frame and, thus, the clamping ring 20 is moved by the auxiliary latch device. 12, against the action of the helical compression spring 20r, towards the lower end of the housing body 6g. In this position, the axis of the hollow cylindrical clamping ring 29 is aligned with the axis of the bolt control member 17. In this position, the bolt control member 17 is wrapped only by the clamping ring 20, there being a certain play between the outer diameter of the bolt control member 17 and the inner diameter of the clamping ring 20. In this position, the bolt control member 17 is freely movable past the clamping ring 20 without tightening.

When external forces do not act on the auxiliary latch device 12, the auxiliary latch device 12 and the clamping ring 20 are urged by the force of the helical compression spring in the direction towards the bolt. On one of its sides, the clamping ring 20 is maintained by its cantilever at the upper end of the groove 6gs of the housing body 6g. On its opposite side to the cantilever, the clamping ring 20 is displaced upwards by the force of the helical compression spring 20r. In this position, the clamping ring 20 is tilted with respect to the bolt control member, ie the axis of the hollow cylindrical clamping ring 20 is no longer aligned with the axis of the bolt control member 17. The The latch control device 17 is fixed by the clamping ring by clamping gear, so that, when the auxiliary latch device 12 is removed, the bolt control member 17 is immobile by tightening.

Therefore, depending on the position of the auxiliary latch device 12, the bolt control member 17 is controlled by the clamping ring 20. The auxiliary latch device 12 is requested on the side of the frame, as is the case when the passive sheet is closed, the bolt control member 17 is freely movable. When the passive leaf is open, when the auxiliary latch is removed, the removal of the bolt control member 17 to the bolt is prevented.

The adjustment organ

The adjusting member 29 is inserted in the end of the bolt control member 17, which is located on the side of the bolt. The adjustment member 29 has at its end opposite the bolt control member 17 an enlarged head which serves for the joint action with the switching element 15. It is essential that the adjustment member 29 can be inserted into the bolt control member 17 variable in depth. This means that the head of the adjusting member 29 protrudes more or less from the end, located on the latch side, of the bolt control member 17, preferably in a variably adjustable manner. It can be foreseen that the adjusting member 29 has an external thread and that the bolt control member 17 is provided with an internal thread at its end located on the side of the bolt. The height with which the head of the adjusting member 29 protrudes from the bolt control member 17 can be adjusted in a variable manner by means of a corresponding screwing. Alternatively, provision can be made for the bolt control member 17 to have a plurality of retaining cavities, so that the adjustment member 29 can be inserted at different heights in the bolt control member 17.

The mode of operation of the bolt control member 17 and the adjustment member 29 is as follows. By actuating the driving device 8 by means of a handle or a motor driving device, the bolt control member 17 moves next to the adjusting member 29 fixed to it moving away from the bolt 11 and approaching the switching element 15. In the In the course of this movement, the head of the adjusting member 29 arrives at a driving edge of the switching element 15, so that the switching element 15 is carried by the adjusting member. Due to the distancing of the adjusting member 15 with respect to the latch 11, the latch 11 is transferred to its pivoting position, since the fork tooth of the switching element 15 leaves the engagement of the locking pins.

Since the adjusting member 29 can be inserted at a variable depth in the bolt control member, it can be adjusted if, when the actuating device 8 is actuated, the switching element 15 is immediately or only dragged after a certain actuation path of the bolt control member 14. If, when the actuating device 8 is operated, the switching element 15 is immediately carried by the bolt control member 17 or only in the course of the actuation path of the bolt control member 17 , depends on the type of use the lock.

In case of using the lock as a top lock in a passive leaf of a two-leaf door, it can be provided that the lock acts in conjunction with a latch lock / passive leaf pin ejector. In case of this use of the lock, it is important that the locking position of the latch 11 of the lock be annulled only after the ejector of the latch / pin ejector lock is actuated. In this case, during the assembly of the lock, the adjusting member 29 is inserted into the bolt control member 17 in such a way that, in the locked position of the lock, there is a relatively large distance between the head of the member of adjustment 29 and the switching element 15.

If the lock is used as the upper lock on a single-leaf door, it is desirable that the locking position of the bolt 11, that is, the inability to rotate the bolt 11, be immediately canceled when the actuating device 8 is actuated. in this case, during the assembly of the lock, the adjusting member 29 is inserted into the bolt control member 17 in such a way that, in the locking position of the lock, between the head of the adjusting member 29 and the member of adjustment 15 there is the smallest possible distance. This means that the adjusting member 29 is inserted into the bolt control member 17 by submerging to a relatively large depth.

As regards the blocking process, in the embodiment shown in FIG. 15, it is provided that the latch 11 acts in conjunction with the auxiliary latch device 12 and / or the latch control member 17 in such a way that the latch 11 can be put into its locked position and / or released by a drive of the auxiliary latch device 12 on the side of the strike, without the need for an actuation of the latch 11 on the side of the strike.

It is envisaged that the release device is made as a clamping device 20 which acts in conjunction with the bolt control member 17 and / or the bolt 11, and that the auxiliary bolt device 12 acts in conjunction directly with a release device. of the bolt control member 12 and / or of the bolt 11.

In contrast, in the embodiments shown in FIGS. 2 to 14, it is provided that the latch 11 cooperates with the auxiliary latch device 12 and / or the latch control device 17 in such a way that the bolt 11 it can only be brought to its locking position and / or released, when an actuation of the auxiliary latch device 12 on the side of the strike has been effected by the retraction of the auxiliary latch device 12 and a latch drive 11 on the side of the strike by the pivoting of the latch 11.

Figure 16 refers to a modified embodiment, in which the pivoting latch 11 is urged, through a spring 11f, to the pivoted position shown in Figure 16. Hereinafter, this pivoted position is designated as the first pivoted position. Figure 16 shows only the module of the latch 11 with the spring 11f, modified in this embodiment. It is the module that is represented for the previous embodiment in Figure 4d. The remaining structure and the functions of the modified embodiment correspond to the embodiment of FIGS. 1 to 15.

The spring 11f is designed as an arm spring. It rests on the support body 13, in which a support pin 13z which is inserted in the support body 13 engages in a housing hole in a spring arm 11f, the other spring arm engages in a housing hole 11o on the latch 11.

The only functional difference of this modified embodiment, with respect to the previous embodiment, consists in that the pivoting latch 11 is pivoted by the spring 11f respectively to the first pivoted position, so that in the open position of the door 1 , the latch 11 adopts this first pivoted position and that, also in the closed position of the door, the latch 11 adopts this first pivoted position. This first pivoted position also exists when the door is retracted from the open position to the closed position and when the latch 11 abuts, by its inlet bevel, with the frame, the latch retracting into the interior of the door leaf also the sense of extension of the bolt bar.

The second position pivoted against the action of the spring 11f is only temporarily maintained, when the bolt bar 7 operated by the handle 8d (see Figure 1) releases the possibility of pivoting the bolt 11 and during this actuation of the handle 8d the bolt 11 is pivoted to the second pivoted position during the opening of the door abutting the frame, and the latch retracts to the passive sheet by a displacement in the direction of extension of the bolt bar. Immediately after reaching the closing position of the door, the pivoting latch is removed and is restored to the first position pivoted by the spring 11f.

This repositioning of the latch 11 of the second position pivoted to the first pivoted position and the removal of the latch occur each time the stop position between the latch and the frame is nullified. This is the case when the door has been put from the closed position to the open position. But this is the case when the stop position of the latch and of the frame which results in the closing position when the door is requested in the opening direction, is still annulled in the closing position and the passive leaf remains in the closed position. . In this case, the latch 11 is pivoted, by the spring 11f, to the first pivoted position.

The spring loading of the latch 11 with the door open has the consequence that in the open position of the door, the latch 11 is always in the first pivoted position. In this case, the latch 11 is in a position in which the possibility of pivoting of the latch 11 can not be blocked by the switching fork 15. The latch 11 can not be blocked by the switching fork, because, being open the as in the previous embodiment, the switching fork 15 is not held by the locking pins 16 in its position that does not block the latch 11, in which it was placed by the unlocking drive during the opening of the door, and the switching fork 15 is out of engagement with the latch 11. Only in the closing position of the door, the switching fork 15 is outside the engagement of the locking pins 16 by the action of the auxiliary latch 12. In in this switching position, the switching fork 15 locks the latch 11. This locking occurs when the latch 11 is in the first pivoted position. The spring 11f acts, as already explained, on the latch 11, in such a way that the spring 11f requests the latch to the first pivoted position both in the closed position and in the open position of the door. This means that, in the closing position of the door, in which the switching fork 15 is in its position that blocks the possibility of pivoting the latch, the possibility of pivoting the latch 11 is blocked by the switching fork 15. This has the advantage that malfunctions which result when, in the absence of the spring 11f, in the closing position of the door after an unlocking of the switching fork 15 by an actuation of the latch bar 7, the latch is prevented has put in its second pivoted position. The second pivoted position of the latch 11 occurs when the latch abuts the frame, when the door in the closed position is requested in the opening direction.

In the case of the non-existence of the spring 11f, this second pivoted position of the latch 11 would be maintained, even if the door is not opened, but the latch 11 stops abutting the frame and the door remains in the closed position. In case of the non-existence of the spring 11f, the latch 11 would engage in its second pivoted position in the housing located on the side of the frame. However, since, in the second pivoted position, the latch can not be blocked by the switching device, in this case, the latch 11 would not be blocked, ie it would be in an unlocked, extracted position. A malfunction of this type is prevented by the latch 11f according to the invention.

A special advantage of the lock is that, when the passive leaf is open, the lock is secured against tampering by manually pressing the auxiliary latch 12 and / or the latch 11. This means that by pressing in the auxiliary latch 12 and / or of the latch 11 with the door leaf open does not trigger the extraction of the lower bolt bar. The control rod 17, which is coupled to the movement with the lower latch bar 17, is in any case held in place by the latching elements 19. In the exemplary embodiment shown, in these cases, at the same time, the latching possibility of the latch is also released. , and therefore, the possibility of pivoting is not blocked.

With the door leaf open, the support stand 13 with the latch 11 supported on it and the auxiliary latch 12 are respectively in their positions extracted from the lock. However, the switching fork 15 is held by the locking pins 16 in a retracted position, the locking pins 16 being in contact with the stop surfaces 15a of the switching fork 15. This means that the catch 11 can pivot freely, since the switching fork 15 is in its retracted position and therefore is out of engagement with the latch 11, that is, the blocking elements 14 do not block the possibility of pivoting the latch 11. The leaf is open of the door, in addition, the control bar 17 is blocked by the retaining elements 19.

Next, it is explained that the door leaf is open, in case a), by the simple manual pressure introduction of the auxiliary latch 12 or in the case b) by the joint pressing of the latch 11 and the auxiliary latch 12 , the lock of the lock does not fire. Only in case c) the locking of the lock is triggered, that is, when the auxiliary latch 12 is pressed in and the bolt 11 is pressed in at the same time, then the latch 11 is released, while the latch 11 is released. auxiliary latch 12 remains in its driven position introduced by pressure.

Regarding a) Single push-in of the latch with the door leaf open

When with the open door leaf the auxiliary latch 12 is inserted by manual pressure into the interior of the lock, the control cams 12s of the auxiliary latch 12 come out of contact with the locking pins 16. However, the springs (not shown) the locking pins 16 apply to their position, which releases the switching fork 15, they can not move the locking pins 16. This is because the switching fork 15 is required by the spring 15r and the force of the spring 15r acts on the locking pins 16 through the stop surfaces 15a of the switching fork 15. This means that the force of the spring 15r is received by the locking pins 16.

Because of the static friction originating between the abutment surfaces 15a of the switching fork 15 and the locking pins 16, the locking pins 16 can not be moved. The force of the non-represented springs trying to force the locking pins 16 into their position releasing the switching fork 15 is not sufficient to overcome the static friction originating between the stop surfaces 15a of the switching fork 15 and the pins blocking 16 due to spring 15r. In this way, the switching fork 15 is secured in its retracted position, even when, with the door leaf open, the auxiliary latch 12 is pressed in. By the fact that the switching fork 15 is held in the position When retracted, the switching fork 15 does not come into contact with the retaining elements 19, which in case of contact would lead to the release of the control rod 17 and the removal of the lower bolt bar. Furthermore, in this position, the teeth of the switching fork 15 do not mesh with the locking elements 14. This has the consequence that the possibility of pivoting the latch 11 is maintained.

Reference ab) Introduction by joint pressure of the latch and the auxiliary latch with the door leaf open If the auxiliary latch 12 and the latch 11 are inserted by manual pressure into the interior of the lock with the door leaf open, the control cams 12s of the auxiliary latch 12 come out of contact with the locking pins 16. At the same time, also the switching fork 15, next to the latch 11 introduced by pressure, moves into the interior of the lock, so that the abutment surfaces 15a of the switching fork 15 are no longer in contact with the locking pins 16. The locking pins 16 are displaced by locking pin springs, not shown, to their position which releases the switching fork 15.

If they are now released, that is to say they are no longer kept under pressure, the auxiliary latch 12 and the latch 11, the following sequence is produced. The auxiliary latch 12, the switching fork 15 and the support stand 13 on which the latch 11 is supported are urged in the direction of extraction respectively by an assigned spring. During this joint removal movement of the auxiliary latch 12, of the switching fork 15 and of the support stand 13, first, the control cams 12s of the auxiliary latch 12 abut against the locking pins 16, so that the locking pins 16 move to their position which locks the switching fork 15. During the following course of the removal movement of the auxiliary latch 12, of the switching fork 15 and of the support stand 13, the abutment surfaces 15a of the switching fork 15 impinge on the locking pins 16, whereby the additional removal movement of the switching fork 15 is stopped and whereby the switching fork 15 is maintained in a retracted position. Only the auxiliary latch 12 and the support stand 13 with the latch 11 supported on it can reach their fully extracted positions.

Also in this case, the switching fork 15 is kept in a retracted position and does not come into contact with the retaining elements 19, which in case of contact would lead to the release of the control rod 17 and to the extraction of the bar of lower bolt. Furthermore, in this position, the teeth of the switching fork 15 do not mesh with the locking elements 14. This has the consequence that the possibility of pivoting the latch 11 is maintained.

Referring to c) Introduction by joint pressure of the latch and the auxiliary latch with the door leaf open, with the subsequent release of the latch, the auxiliary latch being pressed in.

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 the latch 11 are pressed into the interior of the lock. Since also the switching fork 15, next to the latch 11 introduced by pressure, is displaced to the interior of the lock, the stop surfaces 15a of the switching fork 15 are no longer in contact with the locking pins 16. The pins 16 are displaced, by locking pin springs not shown, to their position which releases the switching fork 15.

If now released, that is to say it is no longer introduced by pressure, the latch 11, while the auxiliary latch 12 remains in its actuated position, introduced by pressure inside the lock, the following sequence is produced: the switching fork 15 and the support stand 13 on which the bolt 11 is supported are urged in the direction of extraction respectively by an assigned spring. However, since the auxiliary latch remains in its pressed-in position, the control cams 12s of the auxiliary latch 12 are out of contact with the locking pins 16, i.e. the locking pins 16 remain in their releasing position. the switching fork 15. Accordingly, the switching fork 15 and the latch 11, being requested by respective assigned springs, can completely exit the lock. During this, the teeth 15z of the switching fork 15 come into contact with the locking elements 14 supported on the support stand 13. By the engagement of the teeth 15z, the locking elements 14 are inserted by sliding into the cavities of the teeth. latch retention 11d 11. In this way, the latch 11 can no longer be pivoted 11. Now, the latch 11 assumes its locking position, in which the latch 11 is completely extracted from the lock box being blocked its possibility of pivoting.

During the removal of the switching fork 15, in addition, the switching flanks 15s of the switching fork 15 enter into engagement with the retaining elements 19. During this, the retaining elements 19 are displaced radially away from the bar of control 17, so that the retaining elements 19 no longer engage in the slot 17r of the control rod 17. The locking of the bolt bar 17 is thereby canceled. In this way, the control rod 17 is displaced upwards, and the lower bolt bar coupled to the control rod moves to its extracted position which blocks the blade.

Modified embodiments are also provided with respect to the embodiment of the figures, in which one of the lower latch bars 7 is non-existent. This means that the door is locked exclusively in the area of the upper frame. Functions a), b) and c) exist in the same way. Locking and releasing the bolt bar refer only to the upper bolt bar, since there is no lower bolt bar.

In a further modified embodiment with respect to the figures, a latch 11 can be used that is not pivotally configured around an axis perpendicular to the direction of extension of the bolt bar, but is made movably with respect to the latch bar. to the bolt bar only in the direction of extension of the bolt bar. In this embodiment, functions a), b) and c) described above are present in modified form in the sense that only the latch bar is locked or released as in a), b) and c). As regards the actuation of the latch, the actuation of the latch means the retraction of the latch or the maintenance of the retracted state of the bolt. As for the construction, simplifications result in the exemplary embodiment with the non-pivoting latch 11. The components that refer to the pivoting support and the control of the pivoting possibility can be suppressed or simplified accordingly.
