Abstract

A self-latching lock ( 1 ) having a bolt ( 2 ), a catch ( 3 ), an auxiliary catch pin ( 4 ) and a reciprocator ( 5 ) includes a multi-part latch nut ( 6 ) that permits the deactivation of an nut-idling device ( 8 ) and thereby a temporary activation of the function of door handles preferably by electrically operated remote-controlled actuation. The latch nut ( 6 ) comprises an outer nut body ( 60 ) with two arms ( 61, 62 ) for operating the catch ( 3 ) and the bolt ( 2 ), respectively, as well as two hubs ( 63, 64 ) each connected with a square section of the outer and the inner door handle and coaxially and rotatably positioned parallel to each other inside the outer nut body ( 60 ). The nut-idling device ( 8 ) arranged between the hubs ( 63, 64 ) and the outer nut body ( 60 ) constitutes a coupling which by means of actuators ( 71, 72 ) permits disengagement for each hub ( 63, 54 ).

Description

Self-locking lock and locking system equipped with this

The invention relates to a self-locking lock and a locking system equipped with this.

A number of self-locking locks are known from the prior art. For example, B. the German utility model 298 12 665.6 a self-locking lock, in which when the door leaf is pivoted into the door rebate, the bolt, which is biased in the open position of the door by an elastic element into the closed position, excludes key actuation. This is caused on the one hand by inserting an auxiliary latch on the edge of the striking plate and on the other hand by entering the latch into the striking plate, i. H. With this special self-locking lock, the bolt only closes after the latch has fallen into the striking plate, which prevents premature locking, which could lead to damage to the door frame, etc.

This or similar self-locking locks are preferred for exterior doors of buildings, apartment doors because of their high burglar resistance or hotel room doors. These usually have no handle on the outside of the door, and the doors can e.g. B. can be closed by simply pulling or pressing so that they cannot be opened again from the outside without using a key.

Especially in the hotel sector, but also in office buildings, industrial companies, etc., on the other hand, control and monitoring, such as T. computer-controlled locking systems for use. By means of sensors arranged in the locks, in the doors or in the door frames as well as via corresponding transmission lines or also by wireless remote transmission, the closing status of all doors connected to the central of the locking system can be monitored centrally, and in the same way it is also possible to use the Locks, in the doors or on the door frame of remote controllable devices to change the closed state of the doors, d. H. to bring the doors from the unlocked to the locked state or vice versa from the locked to the unlocked state.

The well-known self-locking locks, which are very well suited for the various types of exterior doors, apartment doors, hotel room doors etc. due to their high burglar resistance, have proven to be relatively unsuitable in combination with the well-known central-controlled locking systems for the following reasons: Locking systems currently in use, e.g. B. for hotel room doors, the lock cylinder openings of the locks are usually covered from the outside, d. H. the doors cannot be opened from the outside simply by manual operation because there is no handle. The door is therefore z. B. via magnetic cards in Zus-unπienmachen with the known arranged in the striking plate and the latch release door openers. Use of the known, self-locking locks described above is not useful in these known locking systems, because their locking can only be unlocked via the latch from the outside of the door. Without a handle on the outside of the door and due to the concealed lock cylinder opening, it is not possible to open a locked self-locking lock from the outside.

For this reason, only locks without self-locking have been used in the known locking systems so far, however, the burglar resistance is very high is restricted because the locking of a door that is closed from the outside only takes place via the latch.

Although z. B. from DE-197 38 938 AI locks with electromotively controlled bolts become known. However, these locks are technically complicated and expensive and have therefore not been used in locking systems to date. The electric motors, which are sufficiently strong for the bolt movement, require a lot of space in the lock, so that the manufacture of such locks in the current standard dimensions is not possible at reasonable costs.

Another option for using self-locking locks in the known locking systems is seen in the additional arrangement of a remote-controlled self-locking lock. With this self-locking lock, an exclusion of the bolt can be prevented if necessary. B. in the case when the door is closed from the outside, so that the locking of the door as with locks without self-locking function only takes place via the latch, and the door can be opened in a known manner by means of a magnetic card and door opener from the outside.

However, this solution makes little sense because the high burglar resistance of the self-locking locks is not used if the door was closed from the outside when leaving the room.

The invention is therefore based on the tasks to extend the remote control of self-locking locks with simple means so that they can fully unfold their burglar-resistant function even in the known modern locking systems under economic conditions. Furthermore, it is an object of the invention to reduce the technical complexity in the construction of locking systems with central control.

According to the invention, the object is achieved by the characterizing features of patent claims 1 and 17.

Advantageous embodiments of the invention form the characteristics of claims 2 to 16. The invention will be explained in more detail below on the basis of preferred exemplary embodiments of the invention in conjunction with FIGS. 1 to 4.

Figure 1 shows the internal structure of a self-locking lock according to the invention as a partially sectioned side view with the lock cover removed, wherein individual assemblies are partially shown schematically;

Figure 2 shows a view similar to Figure 1 of a further embodiment of a self-locking lock according to the invention with a nut idle device and a generator module driven by a gear segment lever for on-site generation of the energy required for actuating electrical components in the lock;

FIG. 3 is a detailed illustration of the nut idling device required for an inventive lock according to FIG. 2;

Figure 3a is a side view of the actuators shown in Figure 3 in plan view;

FIG. 4 shows the diagram of a locking system with central control that is constructed using locks according to the invention.

A first embodiment of a self-locking lock 1 according to the invention shown in FIG. 1 comprises a bolt 2, a latch 3, an auxiliary latch 4 and a change 5. The bolt 2 is from the locking position shown in FIG. 1 either by actuation by means of a shooting cylinder or by Actuation of the follower 6 via the release lever 15 together with the latch 3 can be moved into the open position. During the movement into the open position, the bolt 2 is biased into the closed position by means of a spring 7 or another elastic element and it is then pretensioned by a latch which engages in a recess in the bolt until it is released when the door is closed kept in open position. As an essential component of the invention, the self-locking lock 1 has a preferably electrically driven, remotely operable nut locking device 8. This comprises a biasing spring 31 under a pivot lever 32, the locking lug 33 of which is held in a recess formed on the periphery of the nut 6 by the action of the spring 31 and in this way blocks the movement of the nut 6. The nut locking device 8 can be deactivated by means of electrical remote control. This serves z. B. a pull or lifting magnet 34 which actuates a rocker 35 when excited, which in turn pivots the pivot lever 32 so that the locking lug 33 is lifted out of the recess of the nut 6 and thereby releases the movement of the nut 6.

The nut locking device 8, which can be operated remotely in this way, makes the self-locking lock 1 according to the invention suitable for its use in modern, centrally controlled and monitored locking systems. The remotely operable nut locking device 8 eliminates the need for the "door opener" in the known locking systems in the striking plate or in the door frame, which interacts with the latch 3 and which only offer a low level of burglar resistance This in turn enables the self-locking bolt 2 to be pulled back from the outside of the door via the handle and a release lever 15 when the nut locking device 8 is deactivated. This means that self-locking locks with their high burglar resistance are also used in modern central control In such a locking system, the usual magnetic card can be used for the temporary deactivation of the nut locking device 8 in order to gain access to the room, ie by releasing the nut, the latch and bolt can be locked with the push button After removing the magnetic card, the nut locking device automatically operates again, and when the door is closed and the latch 3 enters the striking plate, the latch 2 triggered via the auxiliary latch 4 also excludes. Because the handle can no longer be actuated as a result of the removal of the magnetic card, the door is locked particularly securely both via the latch 3 and via the self-locking latch 2.

A further advantageous embodiment of the invention is shown in FIGS. 2 and 3. The function of this self-locking lock according to the invention corresponds in principle to that shown in FIG Embodiment described above. In this further embodiment, however, the nut function is not deactivated by a locking device but by an empty device. This means that in this embodiment the actuation of one or both handles is not prevented, but a remote-controlled idle clutch ensures that the movement of the handle or the handles on the outside and / or inside of the door in the cases in which the Door should remain in the swung position, can not be transferred to the nut. In the embodiment shown in FIGS. 2 and 3, the nut to ensure this idling function, as can be seen more clearly from FIG. 3, comprises an outer nut body 60, which each has an arm 61, 62 for actuating the latch 3 and the latch 2. In the interior of the outer nut body 60, the two male connecting bodies 63, 64 for the mandrels of the outer and inner levers are rotatably arranged coaxially and parallel to one another. As FIG. 3 shows, a spring-loaded driver pin 65, 66 with a rounded end face projects radially outward from the periphery of each mandrel connection body 63, 64 into recesses which are in the outer nut body 60 as peripheral tracks 67, 68 of about 50 each ° Angle length is molded. When the pusher is not actuated, the driver pins 65, 66 are located just before the ends of the peripheral tracks, as seen in the direction of movement of the mandrel connecting bodies 63, 64. The ends of the peripheral tracks 67, 68 are formed as stops 69, 70 for the side surfaces of the protruding driver pins 65, 66. When the respective handle is actuated, the side surface of the protruding slave pin 65, 66 strikes the stop 69, 70 after a short idle and takes the outer nut body 60 with it. By this movement of the outer nut body 60 and the arms 61, 62 connected to the nut body, the latch 3 and the bolt 2 of the self-locking lock 1 according to the invention are withdrawn.

In order to prevent the latch 3 and the latch 2 from being retracted when the pusher is actuated by persons not authorized to access, the idle function between the pusher and the nut is achieved in the embodiment shown in FIGS. 2, 3 and 3a in such a way that actuators which can be remotely actuated electrically 71, 72 can be pivoted into the intermediate space between the subscriber pins 65, 66 and the stops 69, 70 when the pushers are at rest. The actuators 71, 72 are arranged on a plate on the outer periphery of the outer nut body. For a better understanding of the function, the two actuators 71, 72 arranged on the plate 73, which in FIG Top view can be seen, shown in Figure 3a in side view, the horizontal position of the actuators is the position causing the idling, which is shown in Figure 3.

By swiveling the respective actuator 71, 72 into the gap between driver pin 65, 66 and stop 69, 70, which is present in the rest control of the handle, the rounded end face of driver pin 65, 66 is countered by the incline on the front of actuator 71, 72 Effect of the compression spring so far pushed back that when the respective mandrel connecting body 63, 64 rotates, the end face of the slave pin 65, 66 comes under the inner periphery of the outer nut body 60 and thus the side surface of the respective driver pin 65, 66 does not counter the respective one Stop 69, 70 presses, and thereby the movement of the respective mandrel connector body 63, 64 is not transmitted to the outer nut body 60. Thus, by pivoting the respective actuator 71, 72, an idle function between the associated pusher and the outer nut body 60 is achieved, thereby preventing the latch 3 and the latch 2 from being retracted. This means that the door cannot be opened despite the lever being pressed. However, authorized users can, for. B. by means of a magnetic card swing out the respective actuators 71, 72 from the gaps between the driving pins 65, 66 and the stops 69, 70 and so deactivate the idle function so that the door can be opened.

The embodiment of the lock 1 according to the invention according to FIG. 2 also advantageously has a gear segment lever 74 which is permanently coupled to the mandrel connection bodies (63, 64), the teeth of the gear segment being in engagement with a pinion of a drive gear of a generator 75 arranged in the lock. Each time the handle is pressed, regardless of whether it is idling or for actuating the closing elements, energy is generated via the gear segment lever 74 in the generator 75 and stored in a buffer memory (not shown), so that the lock 1 according to the invention in this embodiment of any energy supply from the outside or via Batteries to ensure its electrical functions is independent. Even if the latch does not contain enough energy to actuate the electrical or electronic components of the lock after the push button has not been operated for a long time, the required energy can be provided again immediately by pressing the push button. To ensure the panic function, that is, to be able to open the door from the inside at any time simply by actuating the handle without a bowl, magnetic card or the like, the use of a split nut is to be provided when using the nut locking device, in which the nut locking device 8 only points to the outside of the door Nußteü cooperates. In this way, the function of the nut locking device 8 only deactivates the handle on the outside of the door, while the handle located on the inside of the door can be used to withdraw both the latch and the latch at any time and the door to be opened.

When using a nut idle device 8, the P-mic function is ensured in that the actuator 72 is constantly in the non-pivoted state, so that the driver pin 66 of the inner mandrel connection body 64 always strikes the stop 70 of the outer nut body and can move it. In this case, however, it is also possible to consciously override the panic function in certain situations by pivoting the actuator 72 between the driver pin 66 and the stop 70.

In a further advantageous embodiment of the invention, the lock can additionally be a mechanically and / or electrically driven and e.g. B. also have remote-controlled locking device 9 for selectively decommissioning the self-locking function of the self-locking lock 1.

In the exemplary embodiment described here, the locking device 9 has a latching lug 21 which, under the pretension of a spring 22, engages in a recess in the bolt when the bolt 2 is openly controlled and holds the bolt in the open control. The locking device 9 can, for. B. can be solved by remote actuation of a pull or lifting magnet 23 by, as can be seen in Figure 1, the locking lug 9 is pivoted out of the recess of the bolt by pulling action of the magnet 23.

Due to the possibility of central actuation of the locking devices 9 z. B. in emergency situations with simultaneous central deactivation of the nut locking or idle devices 8 outside doors can also be kept open from the outside. In an advantageous embodiment of the invention, it is further provided to arrange a sensor or several sensors on at least one movable building part of the lock, in particular on the bolt 2 and / or the case 3 and / or the auxiliary case 4, in order to determine the current control of the movable building piece or to be able to determine several moveable building blocks.

The determined data can be a control center or a control unit 12 located in the lock 1, which is used to control the electrically driven devices, e.g. B. the nut locking or -leeriaufeinrichtung 8 or the locking device 9 for the self-locking function is used for further processing. The data is transmitted via lines or without wires. A reception and transmission unit 13, which can be combined with the control unit 12, is used for wireless transmission. The receiving and transmitting unit 13 can be a radio receiving and transmitting unit.

In an advantageous embodiment of the invention, the locking of the bolt 2 is additionally dependent on the entry of the door 3 into the striking plate. This prevents premature locking of the bolt, which could damage the door frame or the striking plate.

To ve-π-mitigate the stop noises when excluding the bolt, at least one of the bolt guide elements, ie. H. either the bolt guide bolt or the rear end of the bolt guide slot comprise an elastic damping ghed.

Furthermore, the bolt guide bolt connected to the lock case can be used to increase the bolt counterforce, i. H. in order to further strengthen the burglar resistance, be connected via a bridge element 17 to another part of the lock connected to the lock case or to the lock case itself.

FIG. 4 schematically shows the structure of a visual locking system according to the invention constructed with the use of self-locking locks 1 with a central control device 50.

In the illustrated exemplary embodiment, there are at least all doors in the building with the self-locking locks 1 according to the invention equipped, and constantly locked on the FaUe acting on the nut locking or empty opening device 8 and the excluded bolt 2. An authorized user can use a code reader 54 located next to the door (in the illustration according to FIG. 4, such a code reader 54 is only shown next to the main entrance door) and the central control device 50 to deactivate the nut blocking or empty access device 8, so that the authorized user can actuate it of the outer handle, the FaUe 3 and the release lever 15 can retract the bolt 2. The entry via the code reader releases the nut blocking or empty opening device 8 only for one opening. When the door is fired again, the nut locking or empty opening device 8 and the self-locking bolt 2, controlled by the central control unit, immediately function again, so that the building is secured in a previously unattained manner to prevent burglary.

In the illustrated embodiment, the code reader 54 is connected to the central control unit 50 by a line, while the return signal is transmitted from the central control unit to the lock of the main entrance door via a line-less connection 52. The connections can of course also in other ways, e.g. B. can only be implemented wirelessly.

The central control device 50 is programmed or manually controlled via the operating unit 55, which is also coupled to the central control device 50 via lines 51 or line-less connections 52.

By means of the invention, self-locking locks can now also be used in a simple manner in a modern shooting system, as a result of which the burglar resistance of buildings secured with centrally controlled shooting systems can be considerably improved.

In addition, it is possible to save the previously used door openers, which are arranged in the striking plate or in the door frame and offer little security, including their relatively complicated installation.
