PCT No. PCT/DE96/01381 Sec. 371 Date Apr. 9, 1998 Sec. 102(e) Date Apr. 9, 1998 PCT Filed Jul. 19, 1996 PCT Pub. No. WO97/04203 PCT Pub. Date Feb. 6, 1997A switch for a door or window has inner and outer handles which are both axially fixed to withdraw the locking element of any type of lock. The switch has an actuating shaft which extends between the inner and outer handles for withdrawing the locking element. The actuating shaft has overall dimensions which represent the only dimensions allowing the switch to fit into the lock. An actuating element associated with the inner handle is used to selectively set at least two states of operation of the outer handle. A transmission element inwardly linked to the actuating element extends between the inner and outer handles at least in an area of the actuating shaft that extends through the lock and within the limits of its overall dimensions. A coupling device associated to the outer handle is integrated as a closed unit into the outer handle for putting the outer handle in its selected state of operation, and in particular for selectively coupling or uncoupling the outer handle and the actuating shaft, so that the outer handle may swivel into all of its states of operation.

Description

The invention relates to a switching device for a Door or window fittings and a door, gate or window fitting with such a switching device.

Door or window fittings with means for switching between different functional states are known.

Rotary / tilt fittings for windows are widely used, which open both vertically and vertically allow horizontal axis of rotation or the window keep locked.

A door fitting is known from DE-AS 11 13 649, at which the door handle by a coupling from the associated handle mandrel can be decoupled. This fitting allows in one Position of the clutch a twist of the trigger mandrel and thus opening (or closing) the door while in a second position the door handle can be turned freely, without turning the handle and opening the door (or can be closed).

From DE 78 20 998 U is a window fitting for swing windows known, one in a sign or one Rosette rotatable handle with a bar-like shape a push button-operated for engaging in a striking plate Locking part is assigned, by means of which an actuation of the handle can be prevented.

With these and other known fittings, the Switching between the functional states of that Side of the fitting (i.e. the door or the window), on which the switchover also affects.

There are also known ways of opening a door from one side (outside) from the other side (from inside) either to allow or to prevent.

In addition to the usual locks, they are generally known to lock a door using a key operated Lock bolt the locking of bathroom or toilet doors, where a rotating handle (toggle, Olive) in addition to the spring-operated snap lock (the case) provided locking bolt behind an associated one Strike plate is pushed, after which an actuation of the pulling the snap bolt backwards, but does not open the door.

When locking with a key, every pass is the Door if it is to be kept locked with a double actuation of the lock. This is in many practical cases - for example for authorities that have regular traffic, where the inlet must be controlled, or for Shops after closing when there are still customers in the shop and allow them to leave the store must - too cumbersome. The more employees in one Room or section of building work the more problematic this solution is from an organizational and cost perspective. In addition, the "self-containment" is below the point of view of occupational safety (presence of unblocked Escape routes) and for occupational psychological considerations out to be judged as unfavorable.

Furthermore - especially from the entrance areas from companies, authorities etc. - has long been known as a door opener, their function on an electromechanically remotely controlled Withdraw the abutment for the snap lock in the Door frame is based. The main disadvantage of this solution is in that their execution, especially as retrofitting, a lot of effort for the electrical installation and - in particular for security doors - the frame must be modified.

DE-GM 1.683 917 is a door handle that can be locked on one side known in which the ineffectiveness of the outer jack about an axial displacement of a protruding lever on the inner jack and the outer jack in ineffective State is determined. In this functional state idle handling is no longer possible. Since the External jack, however, recognized by the user as a movement handle this principle carries two risks of accidents - on the one hand due to the lack of it, contrary to the visual appearance Mobility of the external jack in ineffective condition, on the other hand due to the axial displacement of the control lever opposite the door leaf, which creates a risk of pinching leads.

DE-PS 670 268 describes a pusher arrangement two independent pushers with one sliding Coupling link, but its installation is a modification of the castle requires. This arrangement is therefore hardly suitable for retrofitting.

A door locking arrangement is known from US 1 090 772, in the changeover between the functional states effective / ineffective by means of a axially displaceable inner handle. The lack of one axial fixing of the inner handle leads to the fact that a change of state unintentionally when the inner handle is actuated the outside handle can be done. This training also brings with it a pronounced risk of pinching themselves, so the arrangement meets current health and safety requirements not enough.

DE-GM 72 16 046 is a mortise lock with two rotary handles (External / internal jack) known with means that a Easier unlocking from the outside by means of the lock secure the relevant key. The function is also changed here via an axial displacement of the inner handle, with the corresponding accident risks. In addition, the Realization of the square breakthrough of the nut one from have the usual dimension deviating dimension, in particular subsequently expanded, so that this arrangement is not very suitable for retrofitting.

From AU-A-477 028 a switching device is known in which the outer and inner handle via a hollow handle spindle and a lock spindle guided in it are connected and correspond with each other.

A disadvantage of this version is that with the weakened handle spindle contiguous low power transmission or the disadvantages of breaking the hollow Lever spindle and the resulting accident risks or the associated risks Inoperability.

The invention is therefore based on the object of a switching device of the genus mentioned at the beginning, which are easy to operate and made of occupational safety and health occupational psychological point of view is harmless and with commercially available Snap locks with little effort can be retrofitted. In particular, it should not be Danger of pinching and no structural change of the Require door lock.

This task is performed by a switching device with the Features of claim 1 solved.

The invention includes the idea of one completely integrated in the fitting. without external axial displacements accessible parts and no changes on frames, window frames or door locks To provide arrangement. This is universal and easy to use with different lock systems and avoids accident hazards that result from fixing the outer handle as well as from axially displaceable Actuators. It thus fulfills the valid ones strict approval regulations for use in public Buildings and enables retrofitting in conjunction with actuation-certified door locks.

It further includes the thought, one of the inner ones Handle assigned actuator (together with the inner handle also under the term "Switch pawl" provided) with one of the outer Handle associated active element (due to which the external handle in the following also under the term "Puncture pawl" is gripped) over a substantially inside the outer contour of the square mandrel Transmission link is connected. This in turn connects the outer handle to the actuating shaft of the Riegel, i.e. with the standard snap lock over the nut with the square mandrel. The connection between the actuating element and the active element is replaced by a - Realizable in a variety of configurations - switchable (In particular engaging / disengaging) coupling device manufactured.

A equipped with the switching device according to the invention Fitting is particularly suitable for exterior and interior doors as well as gates and can be used in exchange for various commercially available handles and fittings are used, their constructive and aesthetic Specifics are retained.

Different external access authorizations can be entered from the inside can be set optionally. The decisive advantage in use of the switching device designed according to the invention and functional fitting is that a plurality of functions to meet current safety and health and safety requirements fair way in one single fitting is united, with alternative external access authorizations can be adjusted from the inside and the specified security locking function of the used Lock system is not changed. The switching and Functional fitting works independently of the one used Bolt and lock mechanism of the lock, the door opening is not subject to any function selection from the inside, so that the opening of unlocked doors or gates inside the room is always possible.

The switching and functional fitting can be particularly advantageous in public administration buildings in the rooms use in which only temporary public traffic is intended is. During times when there is no traffic provided or all check-in locations are already occupied employees can use the external access authorization from the inside of the room without key operation lock. The staff themselves can, however, at any time the room directly (also without handling a key to have to leave). Should access be allowed again will be an actuator from the inside of the room operated, and everyone can now access the room from enter outside. In contrast, it would be with a room door a conventional fitting during a phase of preventing access required the space from the inside is unlocked here, the passage through the Door is done and then the door is closed again from the outside becomes.

Further application examples can be found in many commercial and private areas, e.g. in laboratories, Business premises, as child safety devices, for garden gates etc. It is particularly important to emphasize that what is to be used Lock system is optional, so any locking security function from outside and inside by choosing the appropriate one Lock and locking system can be realized can. By simply replacing an existing fitting The multifunctionality can be used on doors or gates achieve particularly cost-effectively.

Funktionszustand A) Freigabe:

Tür- bzw. Toröffnung von außen möglich

Funktionszustand B) Dauersperrung:

Tür- bzw. Toröffnung von außen nicht möglich

Funktionszustand C) Teilsperrung:

Tür- bzw. Toröffnung von außen nicht möglich bis innere Klinke/Drehknauf einmal betätigt wurde.

In a preferred embodiment, the following three setting or functional states can be set on the switching and functional fitting from the inside of the room by setting an integrated switching element on the fitting:

Functional status A) Release:

Door or gate opening possible from the outside

Functional status B) Permanent blocking:

Doors and gates cannot be opened from the outside

Functional condition C) partial locking:

Door or gate opening from the outside is not possible until the inner handle / rotary knob has been pressed once.

In functional state A (external handle is effective) is the Switch and functional fitting comparable to a conventional one Door fitting with an outside and an inside handle (or corresponding rotary knobs). The door opening takes place by actuation or withdrawal of the in the castle integrated locking element (snap lock).

In functional state B (outside handle is ineffective) the switching and functional fitting functionally with one conventional door fitting with fixed outside knob and compare an inner jack. An opening of outside is prevented by a withdrawal of the Snap bolt due to a decoupling between the outside handle and actuating shaft of the snap lock not possible is. A rotatable outside handle remains in this state (idle) rotatable so that there is no risk of accident, like them (contrary to the external appearance of mobility) fixed pusher brings with it.

Functional state C is not more conventional with a function Door fittings comparable; it includes in Basically an additional preselection or memory function regarding of the two possible functional states of the outer Handle. The main use benefit of this functional state is that a person inside one temporary outdoor access lock up to Point in time when they own the space through the outside locked door leaves and direct for yourself Wants to enable re-entry into the room.

In a special configuration of the switching and functional fitting are only states A and C on the inside Fitting adjustable, but not state B, so that this is the preferred design variant for lock systems is that no lock bolt retraction by key actuation provide and therefore in the state B there is a risk of self-lockout.

The inner actuating element and the outer active element interconnecting transmission and coupling device the adjustment effect may vary convey physical principles; it can about be designed so that the connection between actuating and active element via a fluid (a hydraulic fluid. Compressed air or similar) or an electrical and / or magnetic field is established. However, are preferred for most fields of application mechanical means that a substantially rigid tensile and / or compressive or Torque transmission element and a by a or compressive force or a torque switchable with which Transmission link connected directional lock (one Have "freewheel").

The transmission link can be double acting, i.e. all Switching between the function or setting states are actively taught. In particular, this can a transmission of both tensile and compressive force or torque in opposite directions of rotation and thus the formation of the transmission link with a suitable structure and material, for example as a pull / push rod or right / left rotating sleeve, require.

Alternatively, however, only one train or only one Pressure transmitting or in just one direction acting torque transmission element and in addition to this counteracts its direction of action automatically acting, in particular designed as a spring element / Reset element may be provided. In an advantageous Training of this type is as a traction transmission element a substantially parallel to the longitudinal axis the actuating shaft of the fitting bolt, in particular in a hole or on the circumference recess the same, running traction rope or band or as Compressive force transmission element arranged accordingly Push rod provided.

This training enables particularly easy use with standard snap locks, their nut snap lock assembly not at all must be changed, as well as with standard hardware systems, their mechanics, handles and lock plates or Rosettes also not changed or only slightly changed Need to become.

The active element provided on the part of the outer handle has in an advantageous training with the standardized structure of snap locks adapted Build an either engaged or disengaged the square mandrel for actuating the trap molded part which has one or more first active surface (s), about it with one between at least two different ones Positions in or out of engagement with the Molding movable engagement part of the coupling device can be related, which in turn is a second Has effective area that corresponds to the first effective area (approximately as a "negative" of this).

The design of the actuating element is the application adapt. In a simple, convenient way to be operated with a handle or a handle with one hand and cost-effective implementation is the actuator as a rocker arm arranged on the pusher neck or designed as a rotating ring surrounding the pusher neck, in particular a common axis of rotation with the as Handle trained inner handle. The axis of rotation the rocker arm can also with that of the pusher enclose an angle and by thumb or finger pull be operable or pressure.

In the sense of the above explanations on the functional or Setting states A, B and C (further below in the description an embodiment also with "0", "II" or "I") is the design of the switching device for setting exactly the two functional states "effective" or "ineffective" of the outer handle as well as the provision from means for converting to the "effective" state the "ineffective" state solely by (single) actuation the inner handle as a universally applicable version prefers.

It can be used especially for fittings that require retraction the trap is not possible using a key is, the actuator only the optional setting the state "effective" or the state in which a transition to the "effective" state by actuation the inner handling is allowed. For others Fittings or if additional one - more detailed below described - safety unlock function integrated is, the actuator has three settings have, namely for the optional setting of the state "effective", the state "ineffective" or the (to be called "temporary release") state, in which a transition to the "effective" state by actuation the inner jack is done.

Increased security against self-lockout or pranksters as well as the possibility of implementing secondary locking functions provides the provision of security or additional switching means that are at least unidirectional Switching between functional states of the Side of the outer handle forth, especially a switch Enable from the "ineffective" state to the "active" state.

The coupling device or the actuating device is preferred. and transmission mechanics designed such that when installing the switching device as a functional state the outer handle in its basic position either "Effective" state (for one also referred to as an "opening door" Door, such as an interior door) or the condition "ineffective" (in the case of a door designated as a "barrier door", an outer door) can be specified.

The safety switching means comprise in a simple one and inexpensive training an opening in the outer Handle (or in the area of the associated rosette), over accessible to the active element and / or the coupling device and its position can be changed. The change the position can be, for example, in the Opening inserted ballpoint pen refill, pocket knife blade or nail file or similar Parts are made that are not for Switching or fitting system belong and easily accessible Show emergency tool.

For the purpose of linking several of the above-mentioned functional features shows the actuation and transmission mechanics in a preferred training a rest and Reset mechanism for the optional setting of a bistable functional changeover state on the actuating element when actuating the inner handle or actuation a safety release device on the outside of the door or by moving an additional, in particular connected with the locking element of the lock, active element automatically in a basic position ("0"). at this version increases the risk of self-engagement or -Locking out through the automatic changeover when falling into the lock banned the door.

The use of the switching device with right and left hinged Doors or windows are covered by such simplified symmetrical design of the coupling device, due to which the switching device in and same version with right and left hinged Doors, gates or windows can be used. An increase in utility value by simplifying operation results here in that the actuating mechanism is so symmetrical is formed that the direction of actuation (about regardless of the door hinge clockwise or counterclockwise) is uniformly selectable.

Another advantageous embodiment is that outward and / or inward function or setting status display means are provided. An ad inward can be easily by suitable Training of the actuator itself or one of these neighboring display area or similar realize one Display to the outside by means of the coupling device or a separate display element linked to the active element.

In addition to manual operation directly on the fitting, in a particularly comfortable - but also more complex - Execution of a remote control provided, i.e. the Actuating element has means for, in particular wireless, Remote control on. These funds can in particular formed by a conventional infrared remote control be as it is known from car central locking systems. The telecontrol device as a whole can at least Include parts of the coupling device so that a functional integration of the actuator and coupling device can result without - just as little as by integrating the active element into the coupling device - the scope of the invention is left.

The fitting in which the switching device according to the invention is used (probably on the most widespread Way) so that the inner and the outer handle as a common horizontal Swiveling axis of rotation, with an actuating shaft for a spring-operated latch connected as a locking element or connectable handle (pawl) are formed.

The switching device can also be used for fittings are used in which at least the outer handle as movable, with an actuating shaft for the locking element connectable door press plate or as a door press bracket is trained.

For both (and other) versions, the provision of effective spring means regardless of the functional state Restoring the outer handle to the idle state of Advantage, as a fitting equipped in this way is the handling habits accommodates and avoids visual irritation.

To further increase the security against burglary, it can be used for some fields of application may be beneficial on the outside Handle means for detecting an actuation of the switching device from outside or destructive interference in this or on the coupling device or the Active element means for recording the actual functional state and one associated with the detection means Provide alarm device. This purpose can have electrical contacts at the safety switch opening in connection with a low current detection device or one in the same place Light barrier or similar fulfill. The alarm device can be directly on the fitting on the inside of the door and / or in a central Monitoring point may be arranged.

Figures 3a to 3j sectional views of a door fitting with a switching device according to an embodiment of the invention in different switching states and views, partly as detailed representations.

Figure 1a gives a schematic representation of the closed (in the detail dotted) Door 7 externally visible parts of a door fitting with a switching device according to one embodiment the invention, seen from the inside of the door. The fitting consists of an outer lock cover 1, an inner lock cover 2, an external function handle, here as Outside jack or lever 3 shown, an inner Handle, shown here as inner pawl 4, and one Rotary lever 5 as a manual actuating element for the actual Switching device (switching element) for adjustment the functional condition of the fitting. The one shown Fitting has three setting states, one on one - Immediately use the position of the rotary lever for display - Switching status display 6 on the inner lock cover are displayed: a state in which the external jack pemanent is effective, a state in which it is permanent is ineffective, and a state in which it is ineffective is, but made effective by actuating the inner pawl (while the actuator in the state "effective" jumps back).

Figure 1b is a schematic representation of the interior of the room visible parts of a door fitting in one opposite Figure 1a modified version in which the switching device via an infrared remote control (known as such) with a transmitter unit 5b 'and one in the Door fitting integrated receiver and actuator unit 5a "is actuated, which is an electromagnetic actuator, an actuator or the like can have. On this is one LED display 6 'for displaying the set Functional or preselected state provided. The remaining Components correspond to Fig. 1. This version is special beneficial in larger government offices with heavy traffic. Executive offices or similar used. where a manual activation directly on the door fitting as not sufficiently comfortable or technically demanding Solution is to be seen.

Figure 2a shows the sketch in the external view in Fig. 1a shown fitting in a horizontal Sectional representation as a functional schematic diagram. As Main components of a standardized. usable in any way Snap lock or latch lock 8 are a snap lock (a trap) 9 and a square push-through element (a so-called nut) 10 shown that those of the standardized Correspond to the castle. The outer jack 3 of the switching and Functional fitting is similar to a conventional one Execution via a modified square mandrel 11 as Actuating shaft for the latch 9 with the inner pawl 4 connected. The square mandrel 11 is - in difference to a conventional mandrel - with an axial continuous (not shown separately in this figure) Provide recess and with in a conventional manner the nut 10 connected via mechanical positive locking. Being in the end protruding outside jack 3 is rotationally symmetrical edited so that - taken by itself - none Has positive locking with the outer jack.

The square mandrel 11 are a direction converter 12 (on the inner pawl 4) and a transmission and clutch mechanism 13 assigned to that on the inside of the door arranged rotary lever 5 with an active element 15 for Connect the outer jack 3 to make it effective or ineffective.

The direction of movement converter - shown here only symbolically 12 sets a rotary movement of the rotary lever 5 in a Axial displacement of the active element 15 by. The latter stands in turn either in engagement or out of engagement with a sleeve-like engagement element 14 on the outer jack 3. By turning the rotary lever 5, the active element 15 axial, i.e. parallel to the square mandrel 11, shifted, to the desired state of engagement with the engagement element 14 and thus optionally an operative connection between External jack 3 and square mandrel 11 and thus ultimately between the outer jack 3 and the latch 9 or cancel. How this happens in detail depends on the specific design, in particular the coupling device and will become more specific using the example below Embodiments described in more detail.

In the outer jack 3 is in the embodiment shown (Optional) through hole 16 provided in one Ballpoint pen refill 16a, a wire or the like be introduced and thus the active element 15 from the outside, even from the inside ago originally released engagement in the engaged position can be pressed. The bore 16 thus functions (together with the ballpoint pen refill) as a safety opening device, via which the integrated switching and Functional mechanics can be adjusted so that a door locked from the inside, security open from the outside can be.

The preselection function mentioned above, in which a switchover from the "ineffective" state to the state "effective" by pressing the inner pawl instead of the Rotary lever takes place, with the help of bistable known per se mechanical switching arrangements (such as a locking disc with spring elements) are executed, the required mechanics in the fittings in the area the inner jack can be integrated.

Fig. 2b is a representation of a slightly compared to Fig. 2a modified version of a fitting, at which the external jack 3 instead of with a simple cylindrical Through hole a lock opening 17 with coding recesses and a suitable one in the system Key 18 is provided with the similarly as with the fitting described above, an opening of the blocked Door 7 can be done from the outside. The remaining parts correspond to those shown in FIG. 2a and are not described again. In a (not shown here) Further training, the external jack can be a commercial one have displaceable and adjustable locking cylinders, via which the functional state of the external jack or -Handled permanently using an associated key can be adjusted.

2c is a schematic diagram of another one Fig. 2a modified embodiment. Here is the External jack 3 with each other on the circumference of the cylindrical passage bore 16 arranged transmitting and Receiving elements 19a, 19b of a mini light barrier arrangement 19 provided. The transmission element 19a (such as an LED) is via a switch 19c (which is attached to the inside of the door can be) and a driver 19d with a voltage source 19e connected, the receiving element 19b via a signal processing stage 19f and power supply 19g with an alarm clock 19h. This gives in the activated state the arrangement 19, i.e. with the switch closed 19c, in the event of an interruption in the passage through opening 16 Light beam due to the introduction of a tool an alarm signal to unlock the lock. The other parts shown here correspond to those 2a.

Figures 3a and 3b show longitudinal sectional views a horizontal, perpendicular to the level of the door leaf Section plane a door fitting 100 with a switching device according to an embodiment of the invention in the both switching states "active" (Fig. 3a) or "ineffective" (Fig. 3b), the square mandrel with the associated Divide to better clarify its shape Is shown rotated 90 °. 3c and 3d show the Structure of the actuator in the vertical plane B-B in Fig. 3a in the "effective" position - from the interior of the room (Fig. 3c) or seen from the door leaf (Fig. 3d) -, Fig. 3e and 3f the structure of the actuating device from the viewing direction from the inside of the room in the "ineffective / unstable" positions (Fig. 3e) or "ineffective / stable" (Fig. 3f), FIGS. 3g and 3h the actuating device in the viewing direction from the door leaf in the "ineffective / unstable" position before (Fig. 3g) or when operating the inner handle (Fig. 3h) and Figs. 3i and 3j are cross-sectional views the coupling device in the vertical plane A-A 3a or 3b in the positions "effective" or "ineffective".

A description is given only for those from the point of view components of the switching device which are essential to the invention given, especially as far as their arrangement and Interaction not easily taken from the drawings can be. Parts or assemblies in schematic Form have already been shown in FIGS. 1a and 2a, are designated by reference numerals based on these figures (e.g. with the number 101 based on Number 1, number 102 corresponding to number 2 etc.).

The fitting 100 shown in FIGS. 3a to 3j corresponds in FIG many parts a conventional door fitting and comes with a conventional latch lock 108 with a latch 109 and a nut 110 inserted.

A modified lock square mandrel 111 has on it Top side (as a result of the graphic rotation mentioned above 90 ° in the figure as the right side) one Recess 111a in which a traction rope 13a runs. At a (described below) facing clutch device, cylindrical end 111b of the square mandrel The recess 111a opens into a central one Hole 111c with an enlarged diameter. In that area of the fitting 100, where the square mandrel 111 in the assembled state of the fitting a rotating ring 105 as an actuating element for the switching device is surrounded by a clamping block 112d which can be clamped to the pull cable 113a, with when fitting the inside of the door fittings a connection between the pull cable 113a and the actuating device the switching device manufactured and at the same time the effective rope length in adaptation to the thickness of the door leaf 107 is set.

The rotary ring 105 provided with an axial curve 105a with a torque-transmitting design ring 102 is between a first housing plate 120a and one second housing plate 120b rotatably and axially secured, this arrangement with an abutment plate 120f for receiving the bearing collar of the inner pawl 104 two screws 121 passing through the door leaf 107 with one Abutment 120c is connected on the outside of the door. In the inner jack neck 104a is a threaded hole in a known manner 104b for receiving a set screw 104c provided, by means of which the inner handle (the inner pawl) 104 non-rotatably and against axial displacement or Pulling off is securely connected to the square 111.

The rotating ring 105 has one with two identical ones on the inside, free curve tracks provided opposite one another Face side, to which two against the first housing plate 120a supported strong compression springs 112a, a rope stone sheet 112b is pressed on. The axial The position of this rope stone sheet is thus determined by the rotational angle position the curved tracks on the inner face 105a of the rotating ring 105, ultimately through it Rotation position, determined.

The rope stone sheet has a wide concentric bore on, in which a two-part rope stone 112c was added between the two, screwed together, Share the above-mentioned clamp stone 112d in the recess 111a of the square mandrel 111 guided, rests. So determined the axial position of the rope stone sheet 112b at the same time that of the clamping block 112d and - since in the clamping block that Pull rope 113a is fixed axially - that of the pull rope 113a. In this way, a rotation of the rotating ring 105 ultimately in an axial displacement of the pull rope 113a and (as explained below) a shift gate 113b converted.

The circuit-securing bistable or stable behavior of the switching device are due to the interaction one connected at one end to the rotating ring 105 and at the other end about an axis 112e pivotable compression spring member 112f and a combined locking and release mechanism 112g realized with a cam edge 120b.1 on the rope stone on the one hand and - by means of a ball thrust piece 112g.1 - with two grooves 105b in the inner surface of the rotating ring 105 on the other hand cooperates.

The combined latching and triggering mechanism 112g has one rotatably mounted latching pivot lever 112g.2 with ball thrust piece 112g.1 and a rotatable release tab lever 112g.3. By means of one facing away from each other Ends of the locking pivot lever 112g.2 and the release tab lever 112g.3 connecting tension spring 112g.4 is the Locking and release mechanism 112g as a self-tensioning system executed. This module is used to set the bistable state (position "I"; Fig. 3e, 3g) and too its cancellation with a defined external influence and causes the switching device to automatically switch over from position "I" to position "0". The defined one external influence is in the embodiment shown especially depressing the inner pawl 104, as shown in the approach in Fig. 3h. This is done by the cam edge 120b.1 of the release tab lever 112g.3 is pivoted, whereby the locking pivot lever 112g.2 its counter bearing loses and the ball push piece out of engagement with the groove 105b in the inner surface of the rotating ring 105 is coming.

The same effect is achieved (regardless of the direction of rotation) a twisting of the outside with cams as well as with an internal hexagon provided shaft 112g.5 by means of a suitable Adjustment element or a device reached over that torque is applied to shaft 112g.5. This enables electromagnetic triggering, a automatic snap lock release or manual safety release from the outside of the door.
