Description

The present invention relates to a lock fitting system with a mortise lock, one latch, a bolt, a first profile cylinder adjacent to a face plate and also has a second profile cylinder which is on the opposite side of the faceplate Side of the first profile cylinder is arranged.

As is well known, lock fitting systems are used only for authorized users People have access to the rooms locked with these lock fitting systems To provide. Therefore, only authorized persons with the corresponding, Provide access keys.

In most cases, the lock fitting systems only have one profile cylinder on, then by the authorized person with the appropriate key can be operated. An example of many are public toilets for the disabled.

But there are also cases where lock fitting systems are required, which are in two separate locking systems must be included. An example for this are e.g. special doors by employees of the municipal utility and energy supply must be operated separately. Another example of this consists of spaces, both by authorized persons as well, in particular in emergencies, by members of the emergency services regardless of the closed state the lock fitting systems must be operated. Conceivable applications are the lock fitting systems for doors, sanitary facilities in hospitals, of hotel doors, possibly darkrooms of hospitals, of security tracts or from public disabled toilets.

These problems could be solved by special mortise locks, which for the Actuation of the bolt have two profile cylinders arranged side by side. This allows you to use this special mortise lock independently of each other provided doors operated by two different groups of authorized persons become. Such a special mortise lock also forms the lock fitting system of the type mentioned at the beginning.

A locking device is described in DE-OS 3008728, that consist of a rotary cylinder lock or several rotary cylinder locks can exist. In one example, one becomes two Cylinder locks existing locking device shown, the one for the two locks is a normal key and one Auxiliary key needed. The first lock needs a turn the locking lug counterclockwise to the lock bolt to advance into the locked position. At the second time The lock is turned clockwise around the lock To be able to close the lock bolt in the release position. In normal operation only the first lock should be operated and the second lock will be locked. A with serves for this an armature provided electromagnet, the armature spatial is arranged and designed so that when not excited Magnet locking the lock bit of the second lock engages below. The second lock is blocked. Only at; only when In the event of an emergency, this lock is released by that the electromagnet is excited by energizing and withdraws its anchor against the action of a spring.

However, these lock-fitting systems have the disadvantage that they can be used at any time the two different groups of authorized persons can be operated. This is particularly disadvantageous when there is no emergency and with the Above lock-lock system locked door by an authorized Group of people is opened, but the room closed with it is already occupied by an authorized person. For example, the sanitary Hospital room already occupied by a patient who is then occupied by another authorized person is disturbed. It is also conceivable that in one locked hotel room unpleasant encounters occur, or in one closed darkroom the film to be developed is destroyed. Furthermore can lead to an unexpected opening of a high-security wing to unwanted involvement to lead. It is also possible that a public disabled toilet is already occupied is opened by another authorized person, although this is public Disabled toilet is already occupied.

The invention is therefore based on the object, a lock fitting system Specify the type mentioned, which allows that from one side, for example from the inside one with one equipped with the lock fitting system Door of a room can be locked in such a way and at the same time one normally authorized person no longer has access to this room, this room however, can be opened in emergencies, for example by emergency services.

This task is in a lock fitting system of the type mentioned solved according to the invention in that the first profile cylinder is a profile half cylinder which has a lock bit travel of 180 ° with a closing path of 360 °, the lock bit travel is limited in the way that the latch is not in one of the latches groundbreaking position can be moved.

This makes it possible that the lock fitting system by an authorized Person opened from a first page and from a second page over the second profile cylinder can be closed such that from the first side the door equipped with it, for example, only by emergency services can be opened via the second profile cylinder. So if one with one Door, which has the lock fitting system according to the invention, already occupied Space is locked from the inside, this can only be done by emergency services or the like can be opened.

To make unauthorized access more difficult, it is advantageous if the first Profile cylinder actuated by means of a cylinder key or security key is.

Since an appropriately locked door must be opened quickly in emergencies it is an advantage if the second profile cylinder uses a special socket wrench can be operated, which is quick and easy to insert.

To facilitate handling, it is possible that both the first profile cylinder as well as the second profile cylinder with the corresponding keys from only one first side of the lock system can be actuated. Although different types of operations are conceivable, it is preferred that for actuating the trap at least a doorknob is arranged.

For reasons of relief, it is advantageous that for actuating the second profile cylinder a hand lever is arranged from the side opposite the first side is.

The actuation of the hand lever can be adapted in an advantageous manner, that a connector of the hand lever to the second profile cylinder by one Angle is rotated between 1 ° to 89 °, an angle of 21 ° is preferred.

Although a variety of shapes are conceivable for the connector, it is preferred that the connector is a square connector that fits into a corresponding Square opening of the second profile cylinder engages.

It is particularly advantageous for disabled people if the hand lever is suitable for the disabled is shaped.

To avoid that an authorized person tries in vain to occupy an already occupied one To open space, it is advantageous if on the first side of the lock system or an advertisement for the Lock state of the lock system is arranged.

Although it is quite conceivable to contribute, especially when replacing, of the first profile cylinder this in a not installed or from the corresponding Insert the remote mortise lock, it is advantageous that in a Castle ceiling or in a castle floor a recess for receiving a The locking lug of the first profile cylinder is shaped, as a result of which the first profile cylinder can also be used when the mortise lock is already in the corresponding door is mounted.

The assembly of the second profile cylinder in the mortise lock can be facilitated be that two stops in a castle ceiling or in a castle floor are arranged, which limit the cam travel of the second profile cylinder.

It is advantageous for ergonomic reasons that the stops arranged in this way are that they have the cam of the second profile cylinder at an angle limit of 111 °.

A particularly cost-effective lock fitting system can be achieved if both the lock system and the first profile cylinder commercially available components are.

1 to 3 show a sketch of various closed states of the invention Lock and furniture system.

In Fig.1 the lock fitting system is shown in the state in which it is closed by means of a first profile cylinder 18. This state is, for example then given if with the lock fitting system according to the invention provided door closes an unoccupied room.

A mortise lock 10, shown sketchily in FIG. 1, has a latch 12 and a bolt 14 which penetrate a faceplate 16 for locking reasons and can protrude from it to the outside.

Furthermore, a first profile cylinder 18 adjacent to the face plate 16 is shown, the is a half-profile cylinder, which with a closing path of 360 ° a key way of 180 °. It goes without saying that this cam lock path is arranged in this way is that a locking lug 26 attached to the first profile cylinder 18 in a first recess 26a formed in the latch 14 can engage around the Activate latch 14.

Since the Fig.1 shows the state in which the lock fitting system by means of the first Profile cylinder 18 is closed, of course, the locking lug 26th of the first profile cylinder 18 towards the face plate 16.

It can also be seen from FIG. 1 that a locking lug 30 of a second profile cylinder 20, on the opposite side of the face plate 16 of the first profile cylinder 18 is arranged, not in one, in the bolt 14 for the locking lug 30 of the second Profile cylinder 20 can engage molded recess 30a.

Of course, it is also possible to design the mortise lock 10 in such a way that that the locking lug 30 of the second profile cylinder 20 is also shown in this in Fig.1 State the latch 14 can operate.

However, this is not necessary in the embodiment shown, since this state can only occur in an unoccupied room, so that access to this space is not necessary by rescue personnel or the like, and that Mortise lock 10 can be operated as normal via the first profile cylinder 18 can.

2 shows a state of the mortise lock 10 in which the mortise lock 10 opened by means of the first profile cylinder 18, but not yet by means of the second profile cylinder 20 was closed.

This condition exists when an authorized person has a corresponding one Bowl inserted into the first profile cylinder 18 and actuated it To gain access to a corresponding locked room.

In Figure 2 it can be clearly seen that the locking lug 26 of the first profile cylinder 18 pivoted into a position shown in FIG. 1 by 180 ° is. As can be clearly seen, it is only possible in this position that the locking lug 30 of the second profile cylinder 20 in the corresponding recess 30a of the bolt 14 can engage to the bolt 14 in its closed position method.

As can also be seen from FIG. 2, the locking lug 30 of the second profile cylinder is 20 with respect to the position of the locking lug 26 of the first profile cylinder, that is with respect to the horizontal, by a certain angle towards the bolt 14 pivoted, which is 21 ° in this embodiment.

As shown in Figure 3, the locking lug 30 has the recess 30a for the second profile cylinder 20 move the bolt 14 into a closed position. Here is the lock bit path for the second profile cylinder 20 in this embodiment 90 °. Around this closed position by means of a 90 ° swivel movement, for example Achieving a hand lever (not shown in the figures) can advantageously an example connecting square of a hand lever by 21 ° to the corresponding, also not shown, offset square opening of the second profile cylinder 20 be with a 90 ° pivoting movement of the hand lever the latch 14 in to move its closed position.

As can be seen from FIG. 3, it is not possible in this case to use the bolt 14 the locking lug 26 of the first profile cylinder 18 to operate. This ensures that another authorized person from the one opposite the hand lever Side of the lock fitting system via the first profile cylinder 18 no access obtain or can not unlock the bolt 14.

Furthermore, it can be seen from this Figure 3 that the bolt 14 by means of the second Profile cylinder 20 the mortise lock 10 from both sides via the locking lug 30 can be operated.

4 is a sketch of a castle ceiling or a castle floor 22 of the mortise lock 10 shown. From this Fig.4 measures can be seen, the installation lighten both profile cylinders 18 and 20.

For example, for installation, but also for the replacement of the first profile cylinder 18 an additional recess in a castle ceiling or in a castle floor 22 24 is provided, through which the locking lug 26 of the first profile cylinder 18 passes can be. Since the first profile cylinder 18 is a half-profile cylinder, can its corresponding locking lug 26 does not move into one that is perpendicular to the figures downward position are moved so that its locking lug 26 always off the normal contour of the profile cylinder 18 protrudes.

If this recess 24 has not been worked out, the mortise lock 10 may have to be removed from a door and disassembled to the appropriate Insert profile cylinder 18. This is due to the shape of the recess 24 no longer necessary because the corresponding locking lug 26 of the first profile cylinder 18 used regardless of the installed state of the mortise lock 10 can be.

Furthermore, it can be seen from FIG. 4 that the castle ceiling or the castle floor 22 in the vicinity of the circular region has two stops 28 which to facilitate installation of the second profile cylinder 20, since this has a swivel range the locking lug 30 of the second profile cylinder 20 set.

The lock bit path advantageously describes the locking lug 30 of the second Profile cylinder 20 a certain angle so that the above pivoting conditions of the hand lever can be maintained.

This angle is preferably 111 °.

Of particular advantage in the lock fitting system according to the invention is that both for the mortise lock 10 and for the first profile cylinder 18 commercially available Components can be used. It can be used for the first profile cylinder a locking system with a so-called security key can be used, while a special socket wrench is used for the system of the second profile cylinder can be.

According to the invention it is therefore ensured that with the lock fitting system described activation by an authorized person is possible, however after this permitted operation, another authorized person has no access on this system. Nevertheless, during a use by a legitimate Person unlocked this system by emergency services or the like become.
