Short designation: Drop-lock panic lock that can be opened from the outside, 5

The invention relates to an externally opening drop-lock panic lock with outer and inner handle, a lock-bolt inserted with its head in a passage opening of the lock edge, a parallel thereof which can be moved by means of two-speed key rotation in three different closing positions. and to move back a shifting latch which can be adjusted by the inner handle and a switching latch which can be adjusted by the latter handle to be engaged and disengaged between the inner and outer handle.

A drop-lock panic lock of the above-mentioned type is known from German patent application 2,433,322. This is used for doors, such as transformer doors or the like, which may only be opened from the outside by authorized persons, namely with the help of the appropriate key, while, on the other hand, the lock from the inside is always operated simply by pressing the inner handle, e.g. 20 inner door knob, even then can be opened, if the front lock bolt is closed. In the furthest closed position of the shifting bolt, the outer handle can be coupled to the inner handle and the door can be opened via the outer handle, while the coupling wing in the rest Both shift positions of the shift bolt are outside the path of movement of the outer handle, thus allowing the outer handle to run freely and thus also preventing the lock trap connected to the inner handle to drive continuously by not retracting the outer handle. This drop-lock panic lock is, however, only intended for a single-leaf door, since it can be brought into and out of engagement with its fall and its lock-lock with corresponding holes made in the fixed door frame.

The object of the invention is to improve and perfect a drop-lock panic lock of the above-mentioned type, such that it is also used for the walk-through wing of two wings with a tensioning lock with panic function present on the stand wing, so also 800 1 9 27 -2- 21244 / CV / jb, can be opened with the locked position before opening the tension lock.

According to the invention, this can be achieved in that the switching bolt has a tongue extending through the lock locking head and protruding therefrom on its end side, which tongue is secured by means of a locking lever of a tension lock locked on the opposite door leaf. can be pressed back with panic function. When operating the clamping lock fitted on the side of the stand wing before opening; his corresponding pivoting detent lever first engages the protruding tongue of the switch latch and presses the latter back into the lock latch to then further depress the lock latch and also the switch latch in their locked position.

The drop-lock panic lock is expediently equipped with a retaining plate to be lifted by turning the key as well as actuation of the inner handle with a rotary pin engaging the lock-switch lock in corresponding locking recesses. For this case, according to a further aspect of the invention, a paneling lever is provided on the panic lever, which grips through a driving window present in the lock bolt with movement clearance and protrudes into the movement path behind it of a driving side present on the switching bolt, while further on the switching bolt there is an upward slope, which is lifted up by the panic lever, and which lifts the sealing plate. As a result, the drop-bolt panic lock which can be screwed onto the side of the walkthrough at the same time obtains a further simplification, since the pivot lever, which can be adjusted by the inner handle, which is known in the above-mentioned panic lock for lifting the closing plate, is no longer needed, since the switching latch and also the lock latch can be closed when the inner handle is actuated by the panic lever which is already present when the seal or the rotary pin thereof is simultaneously lifted.

According to a further inventive feature, in order to ensure that the worn-in lock bolt does not change its position when the seal is held closed, there is provided a locking device which locks the lock bolt, which advantageously consists of a spring-loaded locking element accommodated in the head of the lock bolt, that in the locked locking position behind a 800 1 9 27 r * -3- 21244 / CV / jb present on the lock plate, which limits the locking passage opening. edge edge grips. The locking levers present in the tensioning lock are effective with regard to the horizontal means running symmetrically between their locking holes and located on either side thereof, and via driving slots and driving pins protruding therein with carriers rigidly fixed at the inner ends of the tensioning rods hingedly connected and thereby pivoting opposite to each other. This results in a compact construction of the tensioning lock with at the same time a solid design and direct control of the two locking levers by means of the tensioning rods. - 10 The new panic lock can, after all, also be provided with a simple key pull-off barrier if the bolt lock present on the switch bolt for engaging the key bit with a lock that fully rotates the key bit in the inserted position of the lock and switch lock and thereby subtracting the 15 key preventing locking side is provided. In this way it is ensured in a particularly simple manner that the key can only be removed from the outside with the lock and switching bolt closed in advance, that is to say with the door properly closed and the coupling sash in the freewheel position.

The invention will be explained in more detail below with reference to some exemplary embodiments of the construction for the invention shown in the accompanying figures.

800 1 9 27 * · * -4- 21244 / CV / jb. The depicted door closure consists at least essentially of a drop-lock panic lock 2 inserted in an insertion recess 1 on the walk-through wing and a tensioning lock lock 4 inserted in an insertion pocket 3 present on the stand-wing, also with panic function.

The lock 2 of the walkthrough wing has a conventionally designed lock trap 5, which is against the. operation of a spring 6 by a thumb 7 of a two-piece lock swivel 8 and an inner door knob to be inserted in the half-connected half of the thumb 7; On the other swivel half into which the outer doorknob can be inserted, there is a thumb 9. By the spring 11 engaging the two swivel halves via a chain link 10, the thumbs 7 and 9 are in the Figure 1 depicted in the stop position held against the stop pin 12 mounted in the lock case.

With the inner doorknob and counting half bearing the thumb 7, the counting half 14 belonging to the inner handle is firmly connected. The lever 14 carries at its outer end a carrier bolt 16 projecting into an arc-shaped slot 15 of the lock case. A coupling wing 17 is pivotally suspended on the bolt 16, and a hinge pin 18 in the lock case is pivotally mounted. The upper lever arm 19 'then the lever 19 protrudes in the path of movement of the pivotable carrier lever 14 and its carrier bolt 16, respectively.

In the lower part of the lock of the walk-through wing, a lock bolt 20 is mounted in a front and lockable manner, on the one hand via 25 locking head 20 'which is slidably guided in a lock opening 21 of a lock plate 22 and on the other hand via a lock in the lock case, which is mounted by a locking slot 20 "projecting guide pin 23. In the locking there is a substantially square carrying window 20'1" through which the driving pin 19 "mounted on the panic lever 19 engages with movement. Furthermore, the locking 20 has a front at its rear end reclosing is necessary, cooperating with the locking bar of a key or cylinder lock to be inserted into the key opening 25, correspondingly beveled bolt lock 20, while at the top

Two locking recesses 20 and 20 for a rotary pin 26 engaging therein are present on the retaining plate 27 of the locking bolt. The latter is with the aid of three vertically extending slotted holes 27 ', which pass over guide pins 23 and 28 800 1 9 27 r * -5- 21244 / CV / jb. , vertically slidably mounted and by holding the retaining spring 29 engaging on its top in its retaining position. It preferably consists of two mutually connected 5 sealing discs abutting each other against the inner walls of the lock case 30 and the lock cover 31 (see Figures 2 and 4).

Immediately adjacent to the lock bolt 20, a switch bolt 32 is horizontally adjustable. For this purpose it has a longitudinal slot 32 'at its rear end which it grips and is guided over the guide strut 23, while at the front end of the shifting latch 10 a release tongue 32'1 is provided, which is slidably guided in a lock-locking head 20. • present continuous longitudinal cut-out.

The tension-lock lock 4 accommodated in the position wing of the two wings, for instance a fire door, is conventionally provided with a lock swivel 40, 35 circumferentially toothed, which with the ends 41 ', 42' of the racks correspondingly designed as toothed racks. clamping rods 41 and 42 are in a driving connection, so that when the lock 800 1 9 27 ”6- 21244 / CV / jb • swivel 40 is actuated by a doorknob or swivel handle, the two clamping rods 41 and 42 are placed in opposite directions. direction, so that their outer ends (not shown) can be brought into or out of engagement with closing holes in the top door frame or in the bottom, respectively. Furthermore, the release bolt lock 4 accommodates two release levers 43 and 44, which, with respect to the horizontal center line symmetrically positioned between the two lock holes 45 and 46 for the lock catch 5 and the lock control head 20 ', respectively, and on the other side thereof to the clamping bolt hinge bolts' 10 47 and 48 respectively are pivotally mounted. The top release lever 43 engages with a driver pin 43 'in a slot 49' of a driver 49 secured to the inner end of the lower span rod 42, while the lower release lever 44 includes a driver pin 44 'which engages in a slot 50 of a driver 50 secured to the lower end of the top tension rod 41.

The door closure described above has a double panic function, since the two-leaf door also includes the lock and switching latch, which is closed, according to Figures 1 and 2, both of the lock of the walkthrough wing by operating its inner doorknob, as well as from 20 onwards. Tension lock can be opened by actuating the swivel 40 of the tension lock lock only from the inside.

The following takes place:

For closing the lock latch 20 from the non-closed position shown in Figure 3 and with the coupling wing 17 25 switched off, the switch latch 32 is turned by the key bit engaging on the protruding plate 27 in the direction of the lock plate. moved. The carrier pin 33 present on the switching bolt 32 slides the lock bolt 20 into its closed position. During the transportation of the latch, the tongue 32 '' of the switch latch for the lock latch 20 30 delays and remains approximately 5mm for the lock lock head 20 'in the end position shown in Figures 1 and 2.

To lock the latch 20, 32 back, both are moved from the position shown in Figures 1 and 2 to the open position shown in Figures 3 and 4 by rotating the locking beard through 360 °, the switch latch 32 being through the longitudinal slanting flange 32, sliding pin 26, is moved additionally with respect to the lock bolt 20 over a corresponding piece in order to get into its position 80 0 1 9 27 -7- 21244 / CV / jb. The coupling wing 17 remains in its disengaged position, so that the outer knob 9 is thus in the disengaged freewheel position as before, in which a retraction of the trap 5 only via the ° P the panic half of the swivel 14 and the thumb lever 14 and thumb 7 thereof respectively. 5 working inner knob is possible. In the case of locks with three traps, the additional traps located above and below the lock 2 in the walk-through wing, which are provided on the pivot lever 14, can also be operated accordingly. It is not yet possible to use the door from outside for unauthorized persons in this position. To switch on the function of the outside knob, the locking bar 32 is closed by the locking bar or the thumb of the lock cylinder again. One further revolution in the position shown in Figure 5. The coupling wing 17 'is thus pivoted, that it enters the path of movement of the thumb 9 of the outer knob, where 15 is coupled by the thumb to the carrying lever 14. In this way, the trap 5 can then be retracted from the inside as well as from the outside with the door knobs and the door at random from both sides To disconnect the outer doorknob, the switching latch 32 is toothed by a middle 20 links shown in its Figure 3 by forward-closing.

At the from. the panic func- tion to be operated from the walkthrough, the latch 20 pre-connected according to figure 1 and the locking trap 5 are retracted by the inner doorknob to be operated via the intermediate panic lever 19. Thereby the carrying lever 14 under 25 grips the arm 19 'of the panic lever, which is thereby pivoted opposite to the swivel movement. The lower part of the panic lever 19 or its drive pin 19 * * first collides with the

In order to ensure that the enclosed bolt 20 does not change its position when the retaining seal 27 is raised, a locking device is provided in the locking head, which consists of a locking element, for example a locking ball 51 or a locking bolt, accommodated therein, which is accommodated therein. enclosed latch position behind a 'lock plate * 22'ddtttfe £ i'ge,' the passage opening for the latch delimiting “council side · 22 · -thatvati intervenes. this position must be locked positively.

For the panic function to be operated from the clamping lock 4 mounted on the side of the stand wing, the two clamping bars 41, 42 are moved into their retracted position via the lock swivel 40 to be actuated accordingly. The two locking levers 43 and 44 are thereby pivoted into the operating position shown in Figure 3. The lower detent lever 44 herein first strikes the protruding release tongue 32 '* of the switch latch 32 and pushes it back simultaneously with the pivot 26 being lifted, on which the lock latch 20 is then also pushed back by the detent lever 44 colliding against its end face.

Likewise, the lock trap 5 is moved by the detent lever 43 into the open position shown in Figure 3. Both door wings are then unlocked and can be pushed open.

In the above-described opening operation, the clutch wing 17 remains in the disengaged position and thus the outer knob and the associated thumb 9 respectively in the free-running position.

Preferably a bolt lock (not shown) is connected to one of the two clamping rods 41, 42 which holds the spring-clamped clamping rods 41, 42 in their retracted position at the door opening 30. The two door wings are preferably moved back into the closed position by hydraulic door closers or spring belts mounted thereon, whereby a regulator for the closing sequence ensures that the position wing at least collapses before the walk-through wing. A switching drop present on the bolt lock described above releases the clamping rods after colliding with the frame, which can then move under the pressure of the spring loading these rods into the closing hole of the frame and into the recess provided in the bottom. The fall of the subsequent lock of the walk-through leaf 800 1 9 27 * -9- 21244 / CV / jb falls into the closing opening provided on the side leaf of the stand-wing. The walk-through sash can no longer be opened by unauthorized persons from the outside, as the outer knob is in the free-running position g as stated (figure 3). The lock latch 20 and its switch latch 32 can then be brought back into the closed position according to figure 1 with the key of an authorized person.

As shown in Figure 5, the fall-latch panic lock 2 accommodated in the walk-through wing, in principle, also works with a panic function which does not override, so that a simple tension-lock lock 4 'can be used together, without this affecting the structure and the mode of operation of the lock 2 of the walkthrough wing changes slightly. The latter can likewise also be used for a door comprising only one wing, wherein the trap 5 and the lock bolt 20 cooperate with lock holes correspondingly arranged in the fixed door frame.

The panic function of the drop-bolt lock 2 is hereby fully maintained.

The lock 2 for a walk-through leaf 2 shown in Figure 6 differs from the lock shown in Figures 1-5 only in that 2Q in that the bolt lock present on the switching bolt 20 for engaging the key bit with a complete turning of the key bit in blocking the retracted position of the bolt lock 20 and thereby locking the locking side 20 preventing the key from being retracted.

Here, the lock lock is thus designed such that the key and lock bar can actuate the switch lock 32 in its coupling wing 17 and thereby engage the outer door knob, but turn through 360 ° necessary for the retraction of the key. cannot perform. This ensures that when the key is pulled out, the swivel of the outer doorknob is in any case separated from the swivel of the inner knob, since the key must be turned back before pulling away. This is not the case with the embodiment of the lock bolt 20 shown in Figures 1-5.
