Door lock, especially mortise lock.

The invention relates to a door lock, in particular a mortise lock, the locking and / or latching mechanism of which is adjustable by means of a corresponding engagement of a actuating member 5, e.g. a locking cylinder core, which can be brought into engagement therewith with it, that in its rotational movement it is possible to be blocked by a movably alloyed blocking member which can be adjusted from the outside.

By the van. such a door lock can be locked at any time in such a way that it can be brought into the blocking position from the outside such that it cannot be opened or closed by the appropriate key. This is important, for example, if workspaces are accessible by persons with an appropriate key only at certain times of the day, therefore by the workers only during working hours the workers during the free evening. Likewise, in the opposite case, it is possible to prevent the closing of doors, during certain times of the day or occasions, by means of an appropriate key, so that the doors in question are then only closed by the lock handle, so that they can be opened simply by operating the door handle. turn into.

Known door locks of the above-described type are provided, according to French patent specification 1,123,607, with locking cylinders, in which the blocking members to be adjusted by the external operating means are incorporated. They consist of an alloy blocking pin displaceable in a radially extending bore of the locking cylinder housing, which, in particular, is pushed into a radial bore present in the rotatable locking cylinder core, in particular by energizing an electromagnet arranged in the locking cylinder housing. can be moved therefrom. A number of such locking cylinders are always electrically connected to each other in the manner of a follower circuit, while each locking cylinder core has a switching cam disc which can open or close a switching contact associated with the circuit of another closing cylinder electromagnet.

A number of such locking cylinders can subsequently be switched, for example, to a common locking of automobile doors. For the installation of known door locks in buildings are 8101052

however, these locking cylinders provided with electromagnetically or mechanically, hydraulically or pneumatically actuable locking members are not suitable, because they cannot be slid into profiled insertion openings, and furthermore require a difficult mounting and also complicated wiring.

The problem underlying the invention is to provide a door lock, in particular a mortise lock, which, by the presence of a blocking member which can be adjusted by external operating means, can also be manufactured against undesired opening and closing and a suitable flexible cell, the blocking member and its regardless of the installation of a closing cylinder, operating means are thereby considerably easier to mount, resp. to be installed. This object is solved on the basis of a door lock of the type described in the introduction according to the invention, in that the externally operable blocking member between the locking and / or riveting mechanism on the one hand and the pivoting beard of the operating member on the other hand and with this pivoting beard can be brought into blocking intervention. This results in a door lock, the opening and closing mechanism of which, in the case of the actual door lock, can be pre-accommodated and can be provided with a wiring, irrespective of the circumstance of the regular first subsequent insertion in the key, respectively. rotatable operating member, which thus can be made either from a usually complete locking cylinder with the swivel-shaped thumbs or from a key which simply carries the swivel, respectively. key tube may exist. The adjustable blocking member with its externally controllable means can easily be mounted in the door lock and, in the case of electromagnetically externally controllable means, can also be easily wired, without the subsequent installation of the pivot-carrying operating member in the door lock, in any way, needs to be taken into account.

In order to block the swivel beard as desired, the blocking member is generally to be brought into the bypass region located between the rest and carrying pivot of the swivel beard or to be moved outside of it, so that this co-operates directly with the swivel beard of the operating member. However, with a door lock provided with a regulator, it is also possible to arrange the blocking member in such a manner, 8101 052 -3-.

arranging the blocking member such that blocking of the pivoting beard occurs indirectly via the locking holder, so that the blocking member can be brought into a blocking position blocking the holder.

Operation of the blocking member from the outside can take place in: ·· various ways, usually by means of an electromagnet, but possibly also by a mechanical adjusting member, which can then expediently consist of an adjusting slide located in a bent edge of the lock housing.

As regards the blocking member, various variants are proposed according to the invention. For instance, the blocking member can consist of a blocking lever pivotally mounted next to the bypass region of the operating member with a blocking pivotable in the bypass region. ridge exist. However, it can also be designed as a slide slide. Furthermore, there is the advantageous option of designing the blocking member in such a way that it comprises two blocking mugs to be placed in the circulation area thereof on either side of the rest position of the operating member. possession. As a result, the operating member can be blocked in both possible orbital movement directions. For this case, the blocking member may expediently consist of an L-shaped bent slide slide, one leg of which extends parallel to the housing wall of the lock, is fork-shaped and carries the block ends on the fork end, while on the other converted leg of the blocking slide an electro-lifting magnet and engaging this counteracting return spring.

The new door lock with the blocking member which may lock the operating element can be used advantageously in so-called emergency call systems, where this must fulfill two different functions: Firstly, the house or house 30 must be secured in such a way that it is accessed by unauthorized persons is always prevented. On the other hand, however, the door lock must allow the emergency door to be opened by a rescuer in case a person in need of help has asked for help. To this end, the door lock according to another essential feature of the invention has, in addition to its actuating member which can be blocked by the blocking member, another actuating member which can be rotated by an appropriate key and which can be brought into engagement with the same locking and / or latching mechanism 8101052-4- . Advantageously, the door lock has for this purpose two adjacent cylindrical or cylindrical locking cylinders with different closures, in particular profile cylinders, the closing thumbs of which can be brought into engagement with the recess on the locking shaft and of which one closing thumb by the locking member can be secured. In these cases, the occupant, tenant or owner of a house can open or close the door in the usual way from the inside or the outside with an appropriate key. To this end, he actuates with his key a cylinder which can be closed on both sides, which is arranged on the outside of the door under the fixed door knob on the TO and on the inside under the pressure member.

The fixed knob allows the door to be opened from the outside only with a suitable key, on the other hand, the door can be operated from the inside by the pushing means, if the latch 15 is not closed. The second lock cylinder of the door lock can only be closed from the outside and is intended for an emergency person.

The latter can only open the door if the person in need in the house has made a call for help in advance and subsequently unlocked the locked locking cylinder by the remote control concerned by means of a remote control of the locking block mounted in the lock. creating electromagnet for opening is released. In special cases, both locking cylinders can each be provided with a blocking element to be locked at different times.

The invention is explained in more detail with reference to the drawing, which shows a door lock with a removed cover. In the drawing: figure 1-3 shows mortise locks with a pluggable profile cylinder and an electromagnetically operated locking member, figure b a mortise lock with two profile cylinders and a mechanically operated lock member, figure 5 a mortise lock with two profile cylinders and two closing thumbs. blocking electromagnetically operable blocking members and figure 6 a mortise lock with holder and the latter blocking, electromagnetically operating blocking member.

The mortise lock shown in Figure 1 is as far as 8101052 * S.

-5- "known construction, that this has an adjustable journalled in a lock case 1, an opening located in a converted edge 2, penetrating lock latch 3 with recesses H present in the latch shaft 3 'and a correspondingly profiled openings 5 in the lock case 1 5 and has double profiled cylinders 6 placed in the lock lid, which is secured by a fastening screw 7, which can be operated from the flanged side 2. In addition to the turning path 8 indicated by dashed points, of the swivel beard that can be turned by an appropriate key. 9, in the present case of the closing thumb 9 of the rotary cylinder core forming the rotary actuator, the blocking member 10 is arranged, which here is constructed as a locking lever around the bearing pin and a locking lever. in orbit 8 of closing thumb 9 at. ' pivoting blocking mug 12. Furthermore, there is present on the blocking lifting lever 10 a fork-shaped extension 13, in which the free end of a pivoting lever 15 'to be operated by the built-in electromagnet 1h, which grips around the fixed shaft 16 around the holder 17 of the electromagnet "in particular pivotable. At the lower end 15 * a return spring 17" engages, which retains the operating lever 15 and thus also the pivot lever 10. in the disengaged position. On the other hand, "the electromagnet 20 1½ by electric file control, the operating lever 15 is engaged and the locking lever 10 is pivoted such that the blocking mug 12 enters the blocking position reaching in the orbit 8 of the closing thumb 9. This prevents the closing thumb 9 from being in the bolt 3 retracting meshing rotary position 25. The lock is then locked, so that the bolt "3 cannot be pushed back or extended, even by using an appropriate key. To do this, the blocking lever 10. must first be interrupted by interrupting the power supply to the electromagnet "Ih". be shown in its disengaged position.

In the case of Figure 2, the blocking member is constructed as an L-shaped converted blocking disc '18, of which one leg 18.' runs parallel to the housing wall 1 of the lock and is guided thereon by means of a guide pin 20 extending through the elongated hole 19. The leg 18 'is fork-shaped and has a blocking mug 18 "on both of its fork ends.

On the other leg Ιδ * 1 'of the slider 18 a compression spring 21 engages, which rests against the holder 22 for the double lifting magnet 23 8101052 -6- and thereby the slider 18 · in the drawn, disconnected position likes. If, on the other hand, the electromagnet '23 is energized, the leg 18' 'of the slide is attracted to the action of the return spring 21 by the magnet, thereby bringing the slide 18 into its locking position, in which both blocking lofts 18 "on the opposite sides of the closing thumb 9 enter the orbit 8, whereby. the closing thumb 9 is blocked in both bypass directions.

The embodiment shown in Figure 3 is yerwaht. to that according to figure 1. The difference here is that the blocking element .10 is one around the bearing pin 2k. pivotable double lever 25 is provided, on one end of which the blocking mug to be brought into the orbit of the closing thumb 9 sits 25 ”and on the other end 25" the anchor "-1½.1 · of the electromagnet 1½. via a connection with an elongated hole 26 engages directly.

The door lock according to Figure 1 is provided with two adjacent profiled cylinders 6, 6 'which are fixed by the fixing screw T. While the profile cylinder '6r is actuated in a known manner by an appropriate key and thus the latch' 3 can be slid accordingly, the closing thumb 9 of the profiled cylinder 6 can be swiveled around the pin 11, by means of the pivot blocker 10 and the blocking mug 12 thereof. In this case, the respective actuation of the locking lever 10. is effected by an adjusting slide 27 located in an elongated hole 2 'of the flanged edge 2, which with its bevelled end face 27' against 'a correspondingly bevelled end edge 10f. of the locking lever 10 '. When the blocking slide 27 is pushed upwards from its shown position, sliding of the inclined surfaces 27 "10" causes the locking lever 10 with its blocking mug 12 "to slide. pressed into the orbit of the closing thumb 9, whereby the closing thumb 9 is prevented from coming into engagement with the recess present in the locking shaft 3 '. With this type of lock, for example, a resident who can open or close the door at any time via the profiled cylinder 6f with an appropriate key, a person working in the household, who taught the profiled person only with the appropriate key. .cylinder 6 can control access to the home only at certain times of the day.

The bolt mortise lock shown in Figure 5 is also 8101052. . -7-.

once fitted to two profiled cylinders 6, 6 '* which, if necessary, are fitted under each other.

In this case, however, both closing thumbs 9 »9 'are blocked by a blocking member 28, respectively. 28 'in the orbital movement to block choice. In the present case, the two blocking members consist of rollers present at the ends of the beacon of two 1¼ electromagnets, the pins 29 29 29 carrying the rollers simultaneously in elongated holes 30. 30 "from the lock case. At the other end of the anchor, twisted springs 31 »31 'grip. 10, which holds the anchor 1b 'and the rollers 28, respectively. 28 'in the disengaged position. By means of a remote control, the two electromagnets 14 collide independently of one another. current are energized, therefore the two closing thumbs 9 »9 are blocked independently of each other in the circulation movement. Such an on-T5 construction of the lock is advantageous, for example, for factory buildings with shift work, so that only the persons working in a particular shift have access to the work space at a specific time, on the other hand they are prevented from entering those spaces at other times. is becoming. It is clear that for this and for other cases the 20 sbt may also serve independently of a number of each other. resp. profiled cylinders to be blocked can be provided. '

In the lock-mortise lock provided with a known holder 32, which is known from Figure 6, the possible undesired shifting of the lock 3 can be prevented by means of a key fitting on the profiled cylinder 6, until the blocking member 33 does not can block the bypass movement of the closing thumb 9, but the retainer 32 will hold. In the present case, the blocking member 33 is designed for this purpose as a slide 33 sitting at the free end of the armature 1U 'of the electromagnet 1U, which, as is the case in Figure 2, via an elongated hole 19 in the cabinet wall of the lock and guide pin 20 extending therein is guided. When the magnet 1¾ is energized and thereby attracted the armature lV, the blocking slide 13. with its lower blocking side 33 * rises above the blocking side 32 * of the holder 32, which is then blocked against sliding upwards by the closing thumb 9. The closing thumb 9 cannot therefore enter the recess U of the latch, so that the latch 3 cannot be closed either.

It is clear that the described embodiments for the blocking possibilities of the individual locking cylinders can be mutually combined, in particular in such a way that the plug-in locks shown in Figures 1-3 and 6 of another known locking cylinder can be provided, which also operates on the same locking and / or riveting mechanism as the locking cylinder to be blocked. Such a double embodiment of. adjacent or superimposed locking cylinders is of particular importance in emergency call systems, where, therefore, two locking cylinders are visible on the housing side of the case, one of which is for the normal user and the another is intended for rescuers after giving an emergency signal. To exclude confusion ,. is the key opening of the locking cylinder containing the locking cylinder to be blocked expediently provided with a movable closing cover, so that • 1-5 the key can only be fed into the locking cylinder when that cover is turned so far that the key channel is released. In this way not only contamination of the cylinder, which is necessary only in an emergency, is avoided, but also an auxiliary position for the normal use of the door lock by the resident, resp. the user of the system. Both cylinders of the new: mortise lock. There are different locking options and can also be used in one or two mutually independent key operated installations.
