Description

Interlocking system for a door.

The invention relates to a locking system for a door or a window, with a self-locking lock, which has at least one lock ratchet and a latch, and with a latch housing, in which

it penetrates the latch in a “locked” position, from now on also called “locked” position.

Interlocking systems with self-locking locks are known both in the field of doors and in the field of windows. In this way, EP 0854261 A1 deduces a self-locking door lock from an interlocking system. The lock of document EP 0854261 A1 presents in detail a latch, a lock ratchet and an auxiliary ratchet in a lock box. In the door interlock state, the latch and the lock ratchet are previously closed in openings of the closing plate applied to a door frame, respectively they penetrate into corresponding recesses in the door frame. The auxiliary ratchet presses the door against the closing plate in the closed state, respectively it is moved backwards by means of the closing plate to the lock box. The opening of an interlocked door of document EP 0854261 A1 is possible, on the one hand, through the operation of a latch from inside the door. In this case, with the auxiliary ratchet moved backwards, by actuating the latch attached to the latch nut, the latch and the lock ratchet are retracted to the door lock, where the latch stops, respectively, it is retained in the lock, and thus does not jump out again, respectively it closes previously, immediately. On the other hand, it is possible to open the door locked from the outer side of the door, where authentication is required through, for example, a corresponding key for a key operated locking system or also through a unit Access control In addition to this from DE 102 37 729 A1, a closing installation for an escape door is known. The lock has two ratchets, where a ratchet can be unlocked by means of a door opener or a key drive and the other ratchet by means of a latch. WO 01/11166 A2 and GB 2 183 285 A2 documents in each case a locking system with lock ratchet that can be locked through the operation of an auxiliary ratchet. To control the closing state of the closing system, there is also an auxiliary ratchet recess that can be released, which is configured to house the auxiliary ratchet.

To close the door, the lock ratchet and auxiliary ratchet, which slide over the closing plate, travel backwards through the closing plate to the lock box. By means of the auxiliary ratchet displaced backwards, a mechanism is preferably operated by means of a pusher plate mechanics that makes it possible, during the subsequent previous jump of the lock ratchet with the door completely closed, also the pre-latch tensioned slide to the closing plate, which locks the door. Door locks of this type are designated according to this also as panic door locks, respectively better self-locking panic, since on the one hand they can be manually opened from the panic side (usually inside a room or a building ), but when the door is closed, the locking mechanism is automatically activated and the door, from the other side, can no longer be opened at least by pushing.

To further increase the safety of door locks of this type, the auxiliary ratchet displaced backward can also control a lock, respectively a latch and lock ratchet retention. This is especially advantageous if the lock ratchet is a folding ratchet. A folding ratchet of this type has been made apparent, for example, in EP 1291479 A1.

However, in known self-locking locks there is the disadvantage that, for handling, an external latch is necessary which, especially for design and safety reasons, is often not desirable. Apart from this, interlocking systems of this type are not very suitable for doors with high pass frequency, respectively windows with high opening frequencies, since each access applicant, respectively opening request, must specifically control each isolated opening / unlocking ( or) by means of an authentication through for example a key. For doors with heavy traffic or windows with high opening frequencies, auto-interlocking locks are thus inadequate.

Each access through one side, almost always the outer side, of a door with an interlocking system of this type thus requires an authorization check activated individually. This has as a consequence that the corresponding keys must be provided to a large number of people, which sometimes implies a considerable loss of security. It is often desirable apart from this to make possible access through the door from the outer side, without the need (or) a corresponding key or an opening, respectively a manual unlocking, from the inner side of the door. This refers, for example, especially to entrance areas with high frequencies of passage as well as to work areas with a high fluctuation of workers. The same also applies to doors that must be able to open from a position away from the door, as is often the case among others for doors adapted for people in wheelchairs as well as in the field of nursing homes and of the hospitals.

To implement such an opener function, such door openers are usually integrated into such door opener doors that can be controlled by means of functionally comparable pushbuttons or means, which normally make it possible to open the door through a lock ratchet control. , respectively, of the door opener ratchet. The previous needs of unlocking a self-locking door lock to open a correspondingly equipped door discard, however, the combination of locks of this type with push-buttons or other remotely actuated opening means. To make possible in this case an opening of the door from a position away from the door, it is therefore required the use of motorized locks, which unlock the interlocked door lock. Motorized locks however involve numerous inconveniences for the user. Apart from the additional manufacturing costs it is also necessary to carry out considerable installation work, since for the operation of motorized locks, for example for the power supply and for the control of the motorized lock, a complicated wiring of the sheet is required. door.

 The invention has therefore set itself the task of indicating an interlocking system for a door or a window with a self-locking lock arranged on the side of the door / window leaf, which makes it possible to unlock the interlocked lock. the state of closing of the door, respectively of the window, without the actuation of a latch or the use of a key and which is appropriate in this way for frequent opening processes. This is intended to make the interlocking system at the same time simple to install and economical to acquire. Moreover, the interlocking system must also ensure an especially high interlocking and unlocking security.

The solution of the invention is achieved with an interlocking system for a door or a window, with a self-locking lock that has at least one lock ratchet and a latch, with a latch housing in which the latch penetrates into a “interlocking” placement, with a combined opener and interlocking function that is provided by an unloader on the side of the latch housing and by a guard unit with a lock ratchet housing chamber, with which the lock ratchet in the interlocked state of the door or of the window functionally engages, where the latch can

move in a controlled manner by unlocking from the “locked” position removed to the “unlocked” position inserted and the lock ratchet that engages in the lock ratchet housing chamber can be released and can be released in particular by the guard unit , and wherein the combined opener and interlocking function controls both the removal of the latch until the "interlock" placement and the engagement of the lock ratchet in the lock ratchet housing chamber as well as the movement of the latch to the placement of " unlocked ”and the release of the lock ratchet that engages in the lock ratchet housing chamber, with a latch retention by which the latch can

retained in a lock-controlled manner in a "unlocked" position, with a ratchet retention

of lock by means of which the lock ratchet can be retained in the closed state of the door or of the window, where the lock ratchet retention can be dissolved by a backward movement

from the latch to the “unlocked” position. The invention thus relates to a system of

interlocking for a door or a window, with a self-locking lock, with a latch housing, with an unlocking and with a guard unit. Known self-locking locks stand out because they have means that when the door is closed, respectively the window, automatically activates a lock interlock, respectively a previous latch lock. Correspondingly, it is not necessary that the manipulator of an interlocking system of this type, for the prior closure of the latch, use keys or comparable means for interlocking. The interlocking interlocking system thus presents in detail in this way a latch, which can be moved at least to a "unlocked" position, in which it is suitable to open the door, respectively the window, and even a "locked" position. in which the door is located,

respectively the window. In the pre-closed locked state the latch penetrates a latch housing, opposite the self-locking lock in the closed state of the door, respectively of the window, which is normally arranged on the side of the fence under a closing plate with suitable recesses.

According to the invention a combined opener and interlocking function is provided. An opener function should in particular be understood as an opening, respectively an unlocking, remotely controlled (or) of the interlocking system, without requiring a key drive, a manual unlocking, respectively a mechanical authorization check of the applicant for access. In this way the interlocking system according to the invention makes possible both the opening, respectively the unlocking, and the interlocking of the interlocking system with the self-regulating lock. The self-adjusting characteristics of the lock are complemented in this way especially in the opener function of the interlocking system.

The interlocking system according to the invention is correspondingly especially suitable for doors with high pass frequencies, in which frequent interlocking and interlocking of the interlocking system is required or desired. In order to provide the combined opener and interlocking function, the interlocking system according to the invention has an unloader on the side of the latch housing and a guard unit, where the lock can be unlocked by means of the unlocking. Only this special combination of functional units allows the extension of a self-locking lock with an opener function for opening, respectively, the frequent unlocking of the interlocking system. The unlocking on the side of the latch housing makes it possible for this to move the latch from the "locked" position to the "unlocked" position inserted into the lock. The unlocking device is further configured in such a way that, in the case of a closing of the door, respectively of the window, the unlocking device can adopt a functional state in which the self-locking lock latch can also be removed again until latch housing chamber. According to the invention, the guard unit is further configured with a lock ratchet housing chamber, wherein the self-lockable lock ratchet in the closed state of the door or window is functionally engaged with the lock ratchet housing chamber. Functional engagement should in particular be understood from now on as a penetration of a partial region of the lock ratchet into the lock ratchet housing chamber, such that an opening of the door, respectively of the window, is blocked among other things as well. by the partial region of the lock ratchet that penetrates the lock ratchet housing chamber. For this, the partial region of the lock ratchet collides, for example, with marginal regions of the lock ratchet housing chamber. For opening the door, respectively, of the window, the lock ratchet that engages with the lock ratchet housing chamber can be released, where in a special embodiment the release is carried out in a controlled manner by a lock ratchet, that is, depending on the state of the lock ratchet and / or the placement of the lock ratchet.

By this, it should be understood from now on both a backward movement of the lock ratchet in the direction of the self-adjusting lock and, thus, a backward movement of the lock ratchet from the lock ratchet housing chamber, as well as other possibilities that dissolve the functional engagement of the lock ratchet in the lock ratchet housing chamber. For this purpose, in particular, means are provided in the lock ratchet housing chamber, which folds outwards, swivels, turns or stuffed so that the lock ratchet can be pressed in the direction of opening of the door, respectively from the window, out of the lock ratchet housing chamber. This applies, for example, especially for trip pawls, but also for folding pawls or regular rotating pawls. In addition to this, types of lock ratchets with controlled locking mechanics on the side of the lock can be released on the lock side, so that when pushing the door, the lock ratchet, for example, is knocked out or rebate from the door. lock ratchet housing chamber and thereby dissolve the lock ratchet gear in the chamber ratchet housing chamber. In summary, the invention thus stands out in particular by a control of the removal of the latch until the placement of "interlocked" and of the engagement of the lock ratchet in the chamber of the chamber ratchet housing by means of the combined opener and interlocking function. At the same time the combined opener and interlocking function also controls the movement of the latch to the

“unlocked” placement and release of the lock ratchet that engages with the housing chamber

of ratchet lock. The combined opener and interlocking function acts in this way to the same extent on the positioning of the latch and on the positioning of the lock ratchet and, therefore, is especially suitable for use on doors with a high passing traffic.

To ensure a functionally impeccable process of opening and closing a door, respectively of a window with an interlocking system according to the invention, the interlocking system also has

a latch retention by means of which it can be locked in a "unlocked" position

controlled by a lock, that is, depending on the state of the lock, and very especially in a manner controlled by a lock ratchet, that is, a function of the position of the lock ratchet. The interlocking system is thus configured in such a way that the dissolution of the latch retention is carried out according to the state of the lock, respectively of the position of the lock ratchet. In this way, for example, a minimum deviation of the lock ratchet can be provided for a process of opening the door, respectively, of the window, which has to be overcome in order to activate the latch retention. This way it can be guaranteed that the

latch is only retained later in its "unlocked" position, if an opening process has been carried out

the door. If the deviation of the ratchet of the lock does not exceed the minimum deviation, the latch is not retained in its "unlocking" position and thus is previously closed due to the self-locking characteristics of the lock used. The latch retention controlled by a lock ratchet thus requires particularly favorable interlocking characteristics of the interlocking system according to the invention.

Apart from this, a lock ratchet retention is provided, whereby the lock ratchet can be locked in the closed state of the door or window. The lock ratchet can also be fixed in this way in its position in at least one position. The lock ratchet retention is thereby configured so that it can be dissolved by a backward movement of the latch to the "unlocking" position, facilitated through the combined opener and interlocking function. The lock ratchet retention is not dissolved correspondingly, until the latch is moved out of the latch housing chamber in the direction of the lock from the placement of

"Interlocked" until the placement of "unlocked". In this way a dissolution of the retention of

lock ratchet until the backward movement of the latch is completed. By fixing the lock ratchet, the resistance capacity of the interlocking system can be increased, for example against attempts at unlocking.

In another preferred embodiment, the unloader has at least one latch pusher to release and lock the latch housing chamber, where the latch can be moved by the latch pusher, with the door closed or with the window closed, from the latch housing chamber until the “unlocked” position. The displacement controlled by unlocking the latch from the placement of "interlocked" to the placement of "interlocked" is carried out in this way by means of a pusher,

respectively latch pusher, which exerts a special force against the direction on the latch

latch latch and thus move the latch from the "locked" position to the "unlocked" position. A pusher in the sense of the invention is correspondingly a

element, which acts on another element, such as the latch, and by moving or tilting the action. Correspondingly, for example, the latch on, respectively against which the pusher acts, is moved by the pusher from one position, such as the "interlocking" position, to another position, such as the "unlocking" position. The pusher moves for this preferably in

a plane, in which the direction of movement of the element to be moved is also located, as in this case for example of the latch. Preferred classes of movement of the pusher are thereby linear displacements and tilting movements, wherein the axis of tilting of the pusher preferably runs orthogonally with respect to the plane of motion. A pusher in the sense of the invention also preferably has a flattened front side, which in the position removed from the pusher, that is to say in the position in which a recess is locked by the pusher, respectively a construction piece has been displaced by the pusher to its position displaced backwards, is almost flush with the surface of the element in which the pusher moves, such as a door fence, respectively of a closing sheet surface. Ideally, the pusher locks the corresponding housing chamber out almost completely in the removed position, such as in this context the latch housing chamber. In this way, on the one hand, effective protection against manipulation can be adjusted and, on the other hand, the entry of impurities can be prevented. In order to move the latch back with the door closed, respectively with the window closed, means are provided in this way in this embodiment and especially pushers, which are

arranged in such a way that they can move the latch backwards from the “locked” position, which penetrates the latch housing chamber, to the “unlocked” position, retracted and moved towards

out of the latch housing chamber.

Preferably, there is a closed ratchet pusher on the side of the fence which, with the door closed or with the window closed, controls the position of the lock ratchet. The lock ratchet pusher can thus be compared with the latch pusher, in that the lock ratchet pusher can move the lock ratchet from the lock ratchet housing chamber in the direction of the lock. The lock ratchet pusher is preferably installed on the fence side and is configured to move the lock ratchet of a door lock back, for example on the side of the door leaf. The lock ratchet pusher makes it possible, therefore, that the combined opener and interlocking function of the interlocking system according to the invention can not only unlock the door, but can press the lock ratchet out of the chamber of Lock ratchet housing, to such an extent that the door, respectively the window, can be opened only by pushing it and thus without operating a latch, respectively without operating a key. An interlocking system of this type is thus especially easy to handle.

The guard unit can be formed, for example, by a recess framed by a closing plate with a lock ratchet stop in the direction of opening of the door. Preferably, however, the guard unit is a door opener and especially a linear door opener, respectively a linear window opener. Especially the door openers are widespread and stand out for their high functional reliability. The integration of a door / window opener in an interlocking system according to the invention thus combines the advantages of a combined opener and interlocking function with the advantages of a door / window opener, such as, for example, switching operable to distance of the interlocking system to a state of "open", respectively "pluggable above". Basically, all known types of door openers are suitable in this context, especially in the field of doors. Because of their special robustness, however, door openers with a rotating ratchet or folding ratchet are preferred.

An embodiment according to the invention of an interlocking system is particularly advantageous, whose combined function of opener and interlocking and especially of unlocking comprises a development control. The development control is primarily used for the coordinated control of the development of the pusher positioning, respectively of the pushers available in the interlocking system, such as the latch pusher and the lock ratchet pusher. This development control thus controls the development of positioning of the various relevant elements, such as, if available, the latch pusher, the lock ratchet pusher and other pushers. The development control thus makes possible a mutually coordinated placement of the available pushers.

Preferably, the development control according to the invention is motor driven and for example has an electric motor, where in a particularly preferred embodiment, the control of the development control is carried out by means of a direct current motor. For this purpose, corresponding connections are specially provided on the side of the unlocking device, which make it possible in particular the power supply of the development control with electric power. Apart from this the interlocking system conveniently presents other connections, which for example can be used to connect to a release installation. A release installation must be understood as meaning a unit, through which an automatic door release process can be activated. This is usually a push button, for example, which is normally installed in a position away from the door and is electrically conductively connected to the interlocking system.

Preferably or alternatively, the opener and interlocking function and especially the unlocking device comprises an electromagnetically operated development control, which has a coil and an armature. Motor-driven development controls and especially electromagnetically driven development controls can be combined especially well with corresponding release facilities and, from the point of view of installation technique, easily.

To control a pusher, respectively several pushers, such as the latch pusher, the interlocking system has a gear. Gears in the sense of the invention are, in particular, part joints, which serve to guide parts along a path, that is, especially guide gears. With this, the use of a wedge gear, especially for controlling at least one pusher, has proved particularly advantageous. A wedge gear in this context designates a gear, in which a guide piece converges cuneiformly with a guided piece. Wedge gears stand out for a particularly quiet and uniform motion transmission.

Preferably, the development control has at least one control board. The control plate is preferably arranged on the side of the door fence, respectively, of the window, in such a way and so that the control plate runs with a plate side in the closed state of the door, respectively of the window, orthogonally with respect to the door leaf, respectively to the window surface, and along the longitudinal extension of the door fence, respectively window, and especially also laterally along the unloader. Such a space-saving arrangement is especially advantageous. With this there is the possibility of arranging the at least one control plate stationary in relation to the fence, or integrating it on the other hand in the preferred embodiment of mobile form in the development control. The term encirclement includes from now on both a door fence and a window fence. Preferably, the at least one control plate is driven by a drive arranged on the side of the fence, directly and especially preferably indirectly through a thrust gear. The control of development controls with it, by means of the resulting own movement, especially the backward movement of the latch from its

"locked" position to the "unlocked" position. For this it is especially preferred that the at least one

control plate moves orthogonally with respect to the thrust direction of the latch and / or parallel to the thrust plane of the thrust latch. To control the movement of the at least one control plate, caused indirectly and / or directly by the drive, the locking system according to the invention preferably has guides, along which the at least one moves control board Guides of this type can be for example rails, drill guides, etc.

In a preferred embodiment, the at least one development control control plate preferably has, at its own discretion, at least one gear element that makes possible a mechanical movement transmission from the control plate to the pusher, respectively to the pushers, such as the bolt pusher. A gear element of this type is preferably a control bezel. The control bezels in the sense of the invention are all gear elements which, because of a control surface with a bevel in relation to a construction piece to be moved, transmit a movement to another element that is in contact with it. . Preferably, the control bezels are in the form of torn holes. In this way, guiding elements usually penetrate, respectively, through these torn holes. These guiding elements applied to a construction piece to be moved, such as the latch pusher and / or a pusher or several other pushers, slide along the control bezel, preferably the control bevel formed by the holes torn. If the control bezel does not run parallel to the direction of movement of the control plate, the guiding element slides along the control bezel and is moved in the direction of the control bevel path, respectively for example of the Torn hole travel.

In a preferred interlocking system according to the invention there is provided for pusher control of means, which are functionally connected to at least one control bezel of the at least one control plate. The at least one pusher and the at least one control bevel of the control plate are preferably arranged therein with respect to each other, such that the at least one control plate moves parallel to the fence, respectively with the greatest possible space saving, and particularly preferably in the vertically mounted state and activates by this movement an orthogonal movement with respect to the fence surface, turned towards the lock, of the at least one pusher that is functionally attached to the At least one control board. This embodiment thus allows the combination of a space-saving arrangement with a high functional reliability of the interlocking system according to the invention. Especially preferred guiding elements for the transmission of movement from a control plate movement to a pusher are bolts, which protrude from the at least one pusher. Here, bolts with a circular cross-section and / or bolts are especially advantageous which, in order to improve the sliding characteristics, respectively to reduce frictional forces between guiding means and control bevels, are provided with additional sliding means. In this way, in particular, the means that guide the at least one bolt pusher are preferably executed as bolts and protrude on both sides of the bolt pusher turned in each case towards a control plate. Basically on the bolts rollers are mounted, by which the friction of the bolts on the elongated guides of the control plates can be considerably reduced. With this, the axis of rotation of the bolts runs coaxially with respect to the axis of the bolt, such that the rollers can roll along and on the contact surface with the elongated guides of the control plates. It is especially advantageous to apply more than one guiding means to at least one bolt pusher, such as two bolts that pass through the at least one bolt pusher. In this case, two bolt ends protrude on both sides of the pusher. This special arrangement of the guiding elements on the at least one latch pusher allows the development control to control, apart from linear movement models of the latch pusher, also especially swinging movements of the latch pusher. A tilting movement is especially advantageous for moving the latch back behind the tester surface of a door leaf.

In a particularly preferred embodiment, the interlocking system has two control plates that run in parallel and are spaced apart from each other, which together control at least one latch pusher. The two control plates are preferably arranged spaced apart from each other, thereby parallel to the plane of movement of the at least one latch pusher, that the plane of movement of the at least one latch pusher is located between the two planes of the control plates. Both control plates are preferably connected to each other through connecting bolts, where the longitudinal axis of the connecting bolts runs orthogonally thereto with respect to the two control plates. These connecting bolts advantageously run at least in their central region in control guides, which are preferably applied stationary in the housing region of the development control on the fence side, and make possible the guided guidance of the plates of control along a direction of travel. Apart from a greater guiding safety of the at least one pusher, by means of this special arrangement, considerably greater forces can be transmitted to at least one latch pusher. Corresponding control guides are for example torn holes.

The combined opener and interlocking function and especially the development control of the unlocking device can

preferably switched to a "permanent opening mode", in which the interlocking system with the door closed or the window closed is in a state of permanent unlocking. A “permanent opening mode” must be understood in particular as a state of operation of the interlocking system in accordance with the

invention, in which the self-locking mechanism of the self-locking door lock is continuously suppressed, respectively the interlocking system with the door closed is in a state of permanent unlocking and the door can thus be opened from both sides . This can be achieved, for example, also after a development of the self-locking mechanism of the lock by means of an unlocking, directly post-connected automatically of the self-locking lock. Such a function is suitable for example for doors in areas with high frequencies of passage, or however also for doors with a day-night operation, in which during the day a general access must be possible and at night it must be obtained a door lock, at least in a sense of passage. In order to obtain an operating state of this type of the interlocking system it is necessary that the latch, during the closing of the door, is not closed previously, respectively, permanently removed. This can be achieved, for example, by proper configuration of development control. Apart from the complete suppression of the extraction of

latch, however, it is also possible to integrate an unlocking routine in the "permanent opening mode", so that after the closing of the door the self-locking mechanism of the lock is activated first. However, in this example of special execution, the locking mechanism of the lock is switched to the "unlocked" position, by means of the unlocking routine, automatically and without prior request.

In one embodiment, which can be used in particular in multiple ways, the interlocking system according to the invention has, in particular, for controlling doors a drive that can be activated from a lowered position, which drives the development control. A lowered position is in the sense of this invention a position that is not arranged either in the door frame or in the door lock. A normal lowered position in the sense of the invention is for example a goal or a housing entrance of a multi-family dwelling with a common housing door. To control, respectively, activate the interlocking process, in the lowered position a push-button is applied, for example, through which the interlocking system according to the invention can be unlocked and / or interlocked with remote control. With this, the development control preferably presents a gear with self-retention. With the help of such a gear, the development control can be held in different positions, without electrical power being consumed to maintain this positioning. For this purpose, for example, a thrust joint actuated through a threaded spindle is suitable, where the drive causes the threaded spindle to perform a rotary movement. The thread path is thus decisive for the transformation of the rotary movement into a preferably linear movement of a part of the development control, especially preferably of the at least one control plate. For this, the threaded spindle preferably travels through a drag python nut with a corresponding internal thread, where the drag python nut has a drag python, for example in the form of a surplus, which is functionally attached to the plate control.

The lock preferably has an interlocking mechanism, which locks the previously closed latch, and by means of the development control, the unlocking of the latch is controlled before the backward movement of the latch to the lock. Self-locking locks and especially self-locking door locks often feature additional locking mechanisms, which lock the latch.

extracted in its previously closed position, respectively of "interlocked". A backward movement of the latch to its retracted position, respectively, of "interlocked" is not possible without prior cancellation of this interlocking mechanism. For this, an unlocking bolt can be provided on the latch for example, which protrudes frontally in a particularly preferred embodiment, in the state of removal and retention of the latch. In this case, unlocking is achieved by means of a pressure, especially on the side of the unlocking and controlled by unlocking, of the unlocking bolt. In another embodiment of the interlocking system according to the invention, an actuation of this unlocking mechanism is further provided by means of the development control, which also carries out the unlocking of the latch before backward movement of the latch. .

Preferably, the unlocking mechanism is configured for this in such a way and that the latch pusher preferably driven by motor of the combined opener and unlocking function, in addition to unlocking the previously locked locked latch, also displaces it towards outside the latch housing. The unlocking and backward movement of the latch are carried out in this way in a combined manner using the latch pusher. Such an embodiment is preferred, since it can be achieved by a simplified structure of the interlocking system according to the invention and especially of the unlocking.

The self-locking lock also preferably has an auxiliary ratchet, where the latch in its retracted position is retained with the auxiliary ratchet removed. The lock also preferably has a tester and a closure plate on the side of the fence, opposite the tester, where the closing plate has recesses to accommodate the latch and the lock ratchet. Apart from this, in this preferred embodiment, an auxiliary ratchet control is available by means of the combined opener and interlocking function, where the auxiliary ratchet can be removed with the door closed, respectively, with the window closed, until a recess in the side of the closing plate to activate the latch retention. According to the invention, in this preferred embodiment, the unloader moves the latch to its retracted "unlocked" position, where the control of the extraction of the auxiliary ratchet and the backward movement of the latch is carried out through the control developmental. In this preferred embodiment, the integration of a combined opener-interlocking function into an interlocking system with a self-locking lock, with an auxiliary ratchet control, is thus achieved. Unlike known interlocking systems with self-locking locks and especially door locks, the interlocking system according to the invention makes it possible both to provide an appropriate opener function for frequent passing traffic and an interlocking function. . This is achieved in particular by controlling the position of the auxiliary ratchet. For this purpose, the closing plate has, apart from a recess for the latch called from now on the recess of the latch, an additional recess in which the auxiliary ratchet can be penetrated with the closed door, respectively, with the window closed. This recess is hereinafter called auxiliary ratchet recess. The latch housing chamber and an auxiliary ratchet housing chamber, which are both connected on the side of the closing plate to the corresponding latch recess, respectively of the auxiliary ratchet, make it possible to remove the latch, respectively from the auxiliary ratchet, in the closing state of the door, respectively of the window. In these housing chambers, the latch can be penetrated in this way, respectively, the auxiliary ratchet, in its removed position, so that the self-locking mechanism remains operative during the closing of the door. However, the possibility of being able to influence and coordinate the positioning of at least the latch and auxiliary ratchet on the side of the closing plate is decisive for the embodiment according to the invention of the interlocking system. The invention also extends to the interlocking systems that do not have any closing plates. This usually affects doors and windows for example with metal frames. On the side of the closing plate, the frame part, which has the auxiliary ratchet recess and the latch recess, refers for these embodiments. In the following, the interlocking systems without closing plate are not specifically treated, where the fundamental features of the invention also comprise interlocking systems without closing plate. In the sense of the invention, self-locking locks controlled by auxiliary ratchet and especially door locks are preferred, since these are especially suitable for the detection and control of opening processes, respectively closing, of doors and windows, since through the auxiliary ratchet it is facilitated to fix the opening state, respectively closing, of the window, respectively of the door, respectively it is possible in a particularly reliable manner and manner.

The functional relationships of a self-locking lock with auxiliary ratchet in an interlocking system according to the invention are explained in more detail below. The observations cited for this by way of example for a door with a self-locking door lock can be transferred to the same extent, in accordance with the invention, also to a window with a self-locking door. In the case of an open door with a self-locking lock with an auxiliary ratchet, at least the lock ratchet and the auxiliary ratchet protrude above the tester from the door lock, while the latch is retained in the lock. door in its position moved backwards. During the closing of the door, especially simply by pushing it, the lock ratchet and the auxiliary ratchet finally come into contact with the closing plate. If the door is still closed, the closing plate presses the auxiliary ratchet and the lock ratchet in the direction of the door lock. Both the auxiliary ratchet and the lock ratchet have corresponding control surfaces for this. Preferably, these control surfaces are obliquely configured, such that the bevel runs in the direction of closing of the door towards the testera. With this, the auxiliary ratchet and the lock ratchet can move linearly in the direction of the door lock. However, alternatively, for example, a tilting movement in the direction of the door lock is also possible. The self-locking mechanism of the door lock is not activated, according to the invention, until the lock ratchet falls into its corresponding recess on the closing plate and the auxiliary ratchet at the same time is still held by the closing plate in position, moved back to the door lock. This mutual positioning of the lock ratchet and auxiliary ratchet activates the latch retention and the latch closes previously, that is, the latch moves from its position of

"Unlocked" retracted to its "locked" position and penetrated into the housing of

latch. The latch is conveniently prestressed for this in its locked position, by means of a spring located in the lock.

On the other hand, an extraction of the auxiliary ratchet in the case of the interlocking system according to the invention with the door locked and locked, which is a fundamental difference with the known interlocking systems, makes it possible to move backwards from the latch to the lock. door with retention following the latch on the door lock. A latch retention is possible with the auxiliary ratchet removed. The interlocking system has a recess in the closing plate according to the invention, to which the auxiliary ratchet can be removed with the door closed. If the latch is moved with the door closed and the auxiliary ratchet removed, by means of the combined opener and interlocking function, especially by means of the unloader to its retracted position, the latch can be retained in the door lock with the door closed. Although the self-locking mechanism has been activated during the previous closing of the door, the interlocking of the door can be canceled in this way without manual influence, such as a key actuation, respectively through an opener function that forms part of the combined opener and interlocking function. Ultimately, an opening of the door is possible, without previously dissolving the self-locking manually or through a key function. In the interlocking systems according to the invention all lock ratchets used in self-locking door locks can be used. The door lock preferably has a trigger ratchet, preferably a spring-loaded trip ratchet or a cross ratchet, although a folding ratchet is especially preferred. In its dimensions, the recesses on the side of the closing plate for the latch, the ratchet and, if necessary, the lock ratchet are designed in such a way that the corresponding closing elements for this latch, auxiliary ratchet and, if necessary, ratchet Lock can penetrate without problems in them. Apart from this other means may be provided, such as for example sliding plates or reinforcements, which ultimately increase the operational reliability of the interlocking system.

Apart from the positioning of the auxiliary ratchet in the closed state of the door, it is also necessary according to the invention, in this embodiment, to move the latch with the door closed from its position of

"Interlocked" removed to its "unlocked" retracted position, to enable unlocking of the

door through the combined opener-interlocking function, respectively without manual intervention in the door lock. The latch moves for this controlled by an unlocker in the direction of the door lock, preferably it moves, and precisely to such an extent that the latch retention can be activated in the retracted position. The latch is preferably moved backwards to such an extent that the front side of the latch turned towards the closure plate is flush with the surface of the tester, and especially preferably the latch is moved backward to that point, that the front side turned towards the closing plate moves at least as a transition to behind the surface of the testera. To cause, respectively, to activate, the retention of the latch is necessary that, in the case of the door lock controlled by auxiliary ratchet, the auxiliary ratchet is not completely removed. The auxiliary ratchet recess can be locked for this. The interlocking system according to the invention can be extended in any total number of latches, lock ratchets and auxiliary ratchets, such that, for example, through the combined opener and interlocking function, several latches can also be moved back to the lock. Door

A fundamental basic idea of the invention thus lies in the guarantee that the changes in the position of the latch and the auxiliary ratchet are developed in coordination with each other, respectively, a certain minimum sequence of modifications of the middle position is controlled and ensures the mode of operation of the combined opener and interlocking function. This is preferably made possible by the development control which, in the case of a lock controlled by auxiliary ratchet, controls at least the extraction of the auxiliary ratchet and the backward movement of the latch in the closed state of the door . The development control is preferably arranged on the side of the closing plate and is arranged with its fundamental components, as viewed from the door lock, behind the closing plate. The development control thus controls the positioning of the auxiliary ratchet and the door lock latch from the side of the interlocking system, opposite to the door lock tester in the door closing state, especially the door fence of a door with a single wing.

According to the invention, the auxiliary ratchet of the door lock is preferably executed in such a way that, when the door is opened, the extracted auxiliary ratchet is moved backwards by the closing plate in the direction of the door lock. The known ratchets are held in the door closing state normally by means of the closing plate in its rearwardly displaced position and, thus, only need a control surface that makes it possible, respectively, controls an introduction of the auxiliary ratchet to the close the door. However, in the interlocking system according to the invention, the auxiliary ratchet can also occur in the closed state of the door in the removed position, in which it penetrates the auxiliary ratchet recess on the side of the closing plate. The auxiliary ratchet is therefore preferably executed in such a way that also when the door is opened, the extracted auxiliary ratchet is moved by the closing plate in the direction of the lock. This embodiment is advantageous, since an opening of the door is also possible without a backward movement apart from the auxiliary ratchet by means of the opener and interlocking function.

Preferably, the auxiliary ratchet has an additional control surface, which is applied in such a way that the extracted auxiliary ratchet can also slide over the closing plate during the opening of the door, where the auxiliary ratchet is pressed by the closing plate, when opening the door, on the control surface in the direction of the door lock. In total, a preferred auxiliary ratchet thus presents a total of two control surfaces, wherein the first control surface controls a sliding of the auxiliary ratchet over the door closing plate when the door is closed, and a second control surface a sliding of the auxiliary ratchet over the closing plate when opening the door. The two control surfaces preferably present, at least in their tip region directed outwardly from the tester, a cuneiform cross section parallel to the plane of tilting of the door, where the cross section widens towards the testera . By means of the control surfaces, the auxiliary ratchet slides backwards, when sliding on the closing plate, preferably in a linear movement or in a tilting movement or in a combination between a linear movement and a tilting movement in the direction of The door lock. The auxiliary ratchet is sized in such a way that the auxiliary ratchet is removed in time when the door is opened, without activating the self-locking mechanism of the door lock. For this it is decisive that the auxiliary ratchet before or simultaneously to the overflow, respectively of the or to the removal of the lock ratchet, can be extracted at least to a point such that a previous latch closure is no longer activated by means of the lock ratchet that it is extracted, respectively that it is challenged.

Preferably, the auxiliary ratchet control is carried out through the development control. Apart from the basic advantages already mentioned above of a development control, the combined control of the auxiliary ratchet control and the control controlled by the latch pusher of the latch has proved to be especially efficient, since in this way they can be especially well coordinated auxiliary ratchet control and latch pusher control.

In order that the auxiliary ratchet with the closed door can be removed to the auxiliary ratchet recess on the side of the closing plate of choice, the interlocking system according to the invention preferably has means that alternately release the auxiliary ratchet recess or, preferably flush with the closing plate surface of the closing plate disposed especially preferably on the side of the fence, they close it, respectively block it, and prevent an extraction of the auxiliary ratchet. The interlocking system presents, in a particularly preferred manner, at least one auxiliary ratchet pusher on the side of the closing plate, which releases or blocks the auxiliary ratchet recess on the side of the closing plate, to which it is removed. at choice the auxiliary ratchet. For this, the at least one auxiliary ratchet pusher is moved on the side of the closing plate preferably in a plane, which runs orthogonally with respect to the surface of the closing plate. Preferred movement classes of the auxiliary ratchet pusher are linear displacements and tilting movements, wherein the tilting axis of the auxiliary ratchet pusher preferably runs orthogonally with respect to the plane of motion of the auxiliary ratchet pusher. Thus, the auxiliary ratchet pusher is designed in such a way, respectively, the movement of the auxiliary ratchet pusher is controlled in such a way that it can move the auxiliary ratchet in the direction of the door lock. Preferably, the auxiliary ratchet pusher also has a flattened front side turned towards the closing plate, which in the position removed from the auxiliary ratchet pusher, that is to say in the position where the auxiliary ratchet recess is locked by the pusher Auxiliary ratchet, is almost flush with the surface of the closing plate. Thus, the surface expansion of the flattened front side is preferably designed in such a way that the housing on the closing sheet surface, in the extraction position of the auxiliary ratchet pusher, is almost filled by the front side of the pusher auxiliary ratchet. This embodiment is preferable, since the entry of impurities in the auxiliary ratchet housing chamber through the auxiliary ratchet recess is hindered.

In a particularly simple embodiment of the interlocking system according to the invention in terms of structure, the auxiliary ratchet pusher is integrated into the development control of the latch pusher. The auxiliary ratchet pusher is specially configured for this by forming a part with the latch pusher. The combined auxiliary-latch ratchet pusher is configured in this way both to lock the auxiliary ratchet recess and to move the latch back to the "unlocked" position. This form of execution is especially economical in its production, since no autonomous development control is required for the control of the auxiliary ratchet pusher.

In an alternative preferred embodiment, the interlocking system according to the invention with auxiliary ratchet control has on the side of the closing plate a first and a second pusher, wherein the first pusher controls, for example, the release or blocking. of the auxiliary ratchet recess in the closing plate, respectively of the auxiliary ratchet housing chamber, into which the auxiliary ratchet with the door closed and the auxiliary ratchet removed, and the second pusher moves for example the latch with the door

closed to its “unlocked” retracted position. Apart from this the basic idea according to the invention also

can be transferred to the use of additional pushers. These can, for example, additionally fulfill a control function in the door ratchet to position the lock ratchet. Alternatively or additionally combinations of pushers may be used for positioning, respectively for the release or blocking of the recesses in the closing plate. However, the interlocking system according to the invention is basically also suitable, regardless of the use of self-locking locks especially controlled by auxiliary ratchet, for the use of interlocking locks in multiple ways and especially door locks. These usually have several latches. Correspondingly, additional pushers can be used in the interlocking system according to the invention, which in each case by themselves or in combination with other pushers control the positioning of the different latches. The corresponding thing is also valid for lock ratchets and additional auxiliary ratchets.

The auxiliary ratchet pusher preferably has means, which are configured to functionally engage at least one control bevel on the side of the control plate. In this way, the auxiliary ratchet pusher control is achieved through a control plate. Means of this type are comparable, in terms of structure and mode of operation, to the aforementioned means of the latch pusher for functional engagement in the at least one control bevel on the side of the control plate. Correspondingly, this is for example also of protruding bolts that, if necessary, are provided with additional sliding means to reduce friction and that for positioning are in contact with the control bezels on the side of the plate of control.

The interlocking system according to the invention preferably has a controlled installation by means of the combined opener and interlocking function, and in particular at least one pressure piece to fix the lock ratchet that penetrates the ratchet housing chamber. lock To ensure a secure interlocking of the interlocking system, the latch housing chamber normally has a clearance relative to the latch, that is, the latch housing chamber is designed larger than is essential. The same is also true for the lock ratchet housing chamber. This additional play of the latch removed to the latch housing chamber, respectively of the lock ratchet that penetrates the lock ratchet housing chamber, requires that the door in the closed state does not make fixed contact for example with a type seal. fence, but can move within the framework of the clearance present in the direction of opening of the door. The fixing device according to the invention fixes for example the lock ratchet in the lock ratchet housing chamber, respectively correspondingly reduces the space available to house the lock ratchet in the lock ratchet housing chamber, then of which the lock ratchet penetrates the lock ratchet housing chamber. Preferably, the fixing system acts against the opening direction of the door on the lock ratchet. In this way, thermal and acoustic attenuation of the door is particularly well achieved, since in the closing state of the door it is guaranteed that the door leaf is pressed firmly against the seal on the side of the fence through the workpiece. Pressure.

It is advantageous that the at least one piece of pressure is moved or tilted, to reduce the clearance of the lock ratchet in the lock ratchet housing chamber in the closed state of the door or window, to an intermediate chamber that runs in the direction of the door or window opening between the lock ratchet and an inner wall of the lock ratchet housing chamber, and the at least one piece of pressure acting on the lock ratchet presses the door or window against the opening direction of the door or window and especially against a seal on the side of the fence. The intermediate chamber in the direction of opening the door or window between the lock ratchet and the inner wall of the lock ratchet chamber is especially suitable for fixing the lock ratchet in the lock ratchet housing chamber, since the implantation of a pressure piece in this region makes it possible, apart from the fixing of the lock ratchet, at the same time a tightening of the door or the window in the direction of the door fence, respectively of window, to guarantee an effective shutter. The fixation and the tightening are produced in this way combined in this embodiment.

The at least one pressure piece is preferably a cuneiform thrust piece. The implantation of a cuneiform thrust piece in a region, preferably in the direction of opening of the door or window, in the lock ratchet housing chamber between the lock ratchet and the inner wall of the chamber of lock ratchet housing, makes possible even uniform and continuous reduction of the free space of movement of the lock ratchet in the lock ratchet housing chamber.

In an advantageous embodiment the at least one piece of pressure can be pressed against the lock ratchet through a lever function. A lever function should now be understood as a support, respectively a configuration of the pressure piece, which makes it possible to tighten the pressure piece, facilitated by the lever, against the lock ratchet that penetrates the ratchet chamber of lock. A lever function is especially suitable for controlling the tightening of the pressure piece, since in this way an especially efficient force transmission can be achieved.

In a particularly preferred embodiment, the pressure piece control is integrated into a development control of the guard unit. The pressure part control, which controls in particular the tightening and loosening of the pressure part when closing, respectively opening the window, respectively the door, is thus in this particularly preferred embodiment a part of the development control , for example the latch. By integrating the pressure part control into the development control, the coordination of the pressure part control with the other processes controlled by the development control is particularly well achieved, such as the latch displacement control and / or the lock ratchet control, so that improper operation can be prevented especially well, which must be attributed to improper control of the pressure piece.

Preferably, the fixing installation has an intermediate piece for the indirect transmission of a force produced in particular by means of the at least one pressure piece and especially by the cuneiform thrust piece, which acts transversely and especially perpendicularly to the direction of movement of the lock ratchet over the lock ratchet. The intermediate piece thus makes it possible to eliminate thrust forces towards the lock ratchet, which act from the pressure piece on the lock ratchet so that the lock ratchet is moved out of the ratchet housing chamber. The intermediate piece is, for example, a plate-like construction piece, which is inserted between the contact region of the lock ratchet with the pressure piece or is pressed onto the lock ratchet. This special embodiment thus makes possible an especially reliable guarantee that the lock ratchet that penetrates the lock ratchet housing chamber is not displaced out of the lock ratchet housing chamber because of the movement of pressure piece.

Likewise, a fixing installation is preferred and in particular at least one pressure piece, which acts on the lock ratchet especially against the direction of opening of the door, respectively of the window, in front of and behind the lock ratchet. The pressure piece acts in this special embodiment, in this way, on two sides on the lock ratchet. By means of an action on two sides of the pressure piece on the lock ratchet, among other things, an especially good latch discharge can be obtained, in the closed state of the door or of the window. In addition to this, the positioning of the window leaf, respectively of the door, respectively of the testera region in relation to the fence is achieved with particular precision.

Preferably, the development control of the guard unit controls the fixing installation and especially the at least one pressure piece. The positioning control of the pressure piece in the lock ratchet housing chamber is thus integrated in the development control and especially in the development control of the guard unit. In this way and manner, incorrect commutations, respectively, defective positions of the pressure piece, can be especially well prevented. In addition to this, this form of execution stands out for a simple structure, because no separate development control is needed for the control of the pressure piece.

For this purpose, the development control presents, in a preferred embodiment to control the fixing installation and in particular the at least one pressure piece, a pressure piece control plate. The control panels save space in particular and thus are advantageous in relation to the installation space available for the combined opener and interlocking function. For the control of the pressure piece it has proved advantageous, apart from the possibility of guiding the pressure piece control plate orthogonally with respect to the closing plate and along the longitudinal extension of the closing plate, respectively laterally to along the guard unit, especially an arrangement of the pressure piece control plate parallel to the closing plate, respectively to the fence path. The pressure piece control plate preferably has at least one control bevel and the at least one pressure piece for controlling the pressure piece at least one means, which is functionally attached to at least one control bevel . With regard to the configuration of the control bezel, especially the statements cited above regarding control bezels also affect this at least one control bevel. Correspondingly, in this preferred embodiment, the pressure piece control plate thus presents a control bevel, for example in the form of a torn hole. The control bezel is functionally attached to a means, such as a bolt, respectively a control pivot, which penetrates the torn hole. By means of a sliding of this means along the control bevel, the control of the position of the pressure piece in the lock ratchet housing chamber is thus performed. This kind of control of the pressure piece stands out for a particularly high operating safety. This is especially advantageous for a configuration of the pressure piece and the pressure piece control plate forming a part, because of the simplified structure.

The pressure piece control plate is preferably disposed in the rear wall region and opposite the lock ratchet input of the lock ratchet housing chamber, such that the pressure piece control plate it moves parallel to the rear wall region to move the position of the pressure piece. A movement of the pressure piece control plate, which takes place in parallel to the rear wall region of the lock ratchet housing chamber and especially in parallel to the fence path, makes a movement of the control plate possible. of pressure piece, which saves in particular space, of the box with which the guard unit is surrounded. The dimensions of the guard unit can thus be maintained in standard margins, so that especially in the field of retrofitting, no additional installation work is needed, such as additional milling of the fence.

In another preferred embodiment, the interlocking system according to the invention also has a preload absorption to discharge the preload of the latch. Preloads in the sense of the invention are produced, for example, by wind loads acting on the door leaf, pressure differences on both sides of the door or, especially, however, also by people, who push the leaf Door in the closed state. Comparable phenomena can also be observed in the case of windows, to make it more complete. Previous loads of this type are especially noticeable and problematic in case of panic, in the case of doors where eg a human mass pushes an emergency exit locked to quickly leave a room. Especially in this case a compression of the latch can be observed regularly, in the case of the usual interlocking system, since it is pressed against a wall region of the latch housing by means of the previous loading acting on the door leaf in its state of extraction. This phenomenon is especially dramatic especially in an emergency case, respectively a case of panic, since there is no unlocking despite an activated unlocking mechanism. Only the integration according to the invention of a preload absorption thus guarantees the reliable unlocking capacity of the interlocking system according to the invention in the case of previous loads acting on the door leaf, in which it absorbs and It deflects the previous loads that act on the door and thus prevents the latch from being loaded with these previous loads and, if necessary, is compressed. An interlocking system with a preload absorption is thus especially safe, since unlocking is possible even in the case of previous loads applied to the door leaf, respectively of forces acting against the door leaf and, in addition from this, no increased unlocking force is advantageously required.

The preload absorption is preferably formed by a lock ratchet stop, preassembled in the direction of opening of the door or window and in relation to the latch, so that the latch can move without preloading. to its position shifted backwards. This ensures that, especially in a case of panic in which the door is pressed in the opening direction, this pressure is transmitted to the lock ratchet stop and is not applied to the latch. The forces required for unlocking are thus decoupled from the previous loads applied to the door leaf, since these are absorbed by the functionally pre-assembled lock ratchet stop. Functionally preassembled in this way it comprises all the positions of the lock ratchet stop, which guarantee that the lock ratchet collides in the opening direction of the first door with the preload absorption, before the latch collides with a region of wall in the door opening direction.

The preload absorption is configured, especially preferably, combined with the fixing installation. This preferred embodiment of the interlocking system according to the invention is thus especially safe, since in this way the advantages of the fixing installation and the preload absorption in an interlocking system according to the invention are obtained. . With this, the fixing system and, in particular, a pressure piece are configured in such a way that it absorbs the previous load that acts on the door leaf in the state of introduction in the lock ratchet housing chamber, in the state of interlocking of the interlocking system. Apart from greater security, especially in case of panic, this interlocking system makes it possible at the same time to more efficiently configure the thermal and acoustic attenuation of a door with this interlocking system.

It has been shown that a configuration of the guard unit as a door opener controlled by an unlocking device, through which the lock ratchet, after the unloader has moved the latch up to the latch, is particularly suitable for the interlocking system according to the invention. the "unlocked" position can be moved to a position that makes it possible to drive the door leaf without a ratchet drive and without a key drive. The function of the guard unit, which is preferably a door opener, in this embodiment depends on the state of the unloader, respectively, it is dependent on the state of the unloader. In this way, the coordination of positioning between the guard unit and the unlocking device is particularly well achieved. The unlocking device and the guard unit, respectively the door opener, can be configured for this as, for example, a common construction unit. The particularity of this interlocking system is obtained from the possibility of making possible access to the door without ratchet drive and without key operation, respectively an opening of the door leaf, despite the self-locking characteristics of the lock . An interlocking system of this type is thus especially easy to handle, since on the one hand an interlocking of the interlocking system is guaranteed when closing the door, while on the other hand for the user there is the possibility of opening the door for example just putting pressure on her.

Preferably, the interlocking system according to the invention controls the closing state of a door with a single wing or of a window with a single wing, where the lock is arranged on the side of the door / window leaf and the unlocking and guard unit on the fence side. The locks are usually arranged on the side of the door / window leaf. Especially in the field of retrofitting it is therefore advantageous to apply the unlocking device and the guard unit on the side of the fence, since in this way it is possible, for example, to use self-locking locks already available.

In an available embodiment of the interlocking system according to the invention, the latch pusher is in the extraction state, in which the latch with the door closed has been moved by the latch pusher until the "unlocked" position , an excess run driven by elastic force, wherein the latch pusher in this position protrudes with a partial region above the unlocking surface opposite the lock or above the closing plate surface opposite the lock. They usually do not directly limit the tester surface and the closing sheet surface, turned towards each other, in the closed state of the door, respectively, of the window. It is therefore advantageous, according to the invention, to move the latch pusher out of the unloader to such a point that the latch moves completely back to the lock, that is, especially with its frontal region in contact with the pusher. latch Therefore, it is necessary for the latch to move backwards to the lock, also through the intermediate space between the closing plate surface and the tester surface. In accordance with the invention, an excess stroke is provided for this, which protrudes above the closing sheet surface with the latch pusher removed and, in this way, makes possible a complete backward movement of the latch. To prevent an inclination of the bolt pusher removed with the latch displaced back when the door is opened, it is advantageous to provide the remaining stroke with an impulse by elastic force. In this way, a slight backward compression of the latch pusher is possible when opening the door, while maintaining the pressure of the latch pusher on the latch. Correspondingly, the latch, when pressing on the door, can be moved back to the "interlock" position, where at the same time an inclination between the bolt pusher and the latch can be prevented when the door is opened.

Preferably, the latch pusher has on the front side, which moves the latch from the position.

from "interlocked" to the placement of "unlocked", a latch contact region. The contact region of

Latch of the bolt pusher thus differs from the remaining part of the bolt pusher by means of a bolt contact region suitable especially for rearward movement of the bolt. In order to enable a uniform backward movement of the latch, the latch contact region has, for example, synthetic material coatings, which reduce friction between the latch and the bolt pusher.

With this, the latch contact region is preferably formed by a control bezel. The control bezel facilitates in a particularly simple and efficient way a backward movement without tilting the latch by means of the latch pusher.

Alternatively, a configuration of the latch contact region with a control roller is preferred. The control roller rolls during the backward movement of the latch along a partial region of the latch or, depending on the embodiment, alternatively along the latch pusher, so that here too they are especially effectively reduced friction forces The force necessary to move the latch back is thus relatively small.

The interlocking system according to the invention is especially suitable for the remote controlled activation of the combined opener and interlocking function. This embodiment allows the interlocking system to be enabled by means of, for example, a push button. In this way, high interlocking safety can be achieved by means of the self-locking characteristics of the door lock. On the other hand there is a high comfort of handling, because especially in office buildings or family homes the interlocking of the interlocking system can be activated remotely. In this way it is not necessary to unlock the interlocking system manually and in the field for each unlocking process.

The unlocking and / or the guard unit is / are preferably a linear opener. The working principle of linear openers is known for example from EP 1 132 554 A2. Linear openers stand out for their robust construction mode and have already proven their worth in the best way especially through their outstanding operational safety. According to the invention, the integration of a linear opener in an interlocking system with a self-locking lock occurs.

Preferably, the combined opener and interlocking function features a modularly structured unloader with at least two insulated modules. An isolated module should be understood as a constructively coherent unit. A modularly structured unlocking device is advantageous in that here an adaptation of the unlocking device to constructive particularities is particularly well achieved, such as those produced especially in the field of retrofitting.

Thus, it is advantageous that the modularly structured release device has at least one latch module to control the position of the latch. By dividing the unlocking components into at least one latch module, the adaptability of the unlocking device to particularities of the interlocking system is further increased. The unlocking device can thus be adapted, for example, to multiple interlocks, by means of which several latch modules are connected in parallel.

In a special embodiment, the modularly structured unloader also has an auxiliary ratchet module to control the position of the auxiliary ratchet. In this way, the modular unlocking device can also be retrofitted in an application with auxiliary ratchet-controlled door locks, such as those often used especially in the anti-panic field.

An interlocking system according to the invention with a multiple interlocking is especially safe and thus preferable, wherein the multiple interlocking is controlled through the combined opener and interlocking function. Multiple interlocks usually have, apart from a main lock latch, at least one other latch and especially two additional secondary lock latches, so that the door in the locked state has a greater anti-theft effect. The interlocking system according to the invention in this case has several unlocks for unlocking the main latch and secondary latches, which are controlled autonomously, or several unlocking modules that are connected in parallel and controlled together.

Basically all types of lock known in the state of the art are suitable for the interlocking system according to the invention. However, cross ratchets, roller ratchets, oscillating ratchets, tilting ratchets (drop ratchets), crankshaft ratchets and firing ratchets have proven to be especially appropriate because of their high reliability. Particularly preferred, the latch retention in the lock box is controlled by the movement of the lock ratchet and especially of a swinging ratchet. Such a coupling of the latch retention to the movement of the lock ratchet guarantees, for example, especially well the activation of the locking state after reaching a fixed position of the lock ratchet. Such a detection is achieved especially well with an oscillating ratchet. In this way it is possible to prevent unwanted removal of the latch, for example with an open door.

In a particularly preferred embodiment, the latch is a motorized latch with a switch, by means of which the motorized latch is moved from the "locked" position to the "unlocked" position, and where the unloader activates the latch switch motorized. Basically in the

field of self-locking door locks the latches are normally driven by elastic force

and have an activation mechanism, which makes possible an "automatic" pre-activation activated by the drive

by elastic force, while closing the door. However, alternatively, gear-controlled latches are also known, eg in motorized locks, which can usually travel through a

gear, which is driven by a motor, between the placement of "unlocked" and the placement of "locked."

Usually available for this purpose are gear elements, such as threaded spindles, which cause a self-retention of the gear, so that the latch, unlike in a latch driven by elastic force, has an almost stable positioning also in an intermediate placement between the placement of

"Unlocked" and placement of "locked." The motorized latch has according to the invention a

switch, whose activation by means of the unlocking activates a recoil of the motorized latch to the position

of "unlocked." The switch on the motorized latch is thus arranged preferably

frontally, since in this way an actuation of the switch by means of the unlocking device can be particularly well realized.

A further aspect of the invention lies in a method of interlocking an interlocking system according to claim 1, which comprises the closing of a door or a window, the extraction of a lock ratchet, the absorption of a previous load, in where the lock ratchet is pressed by a pressure piece in the lock ratchet housing chamber against the direction of opening of the door, the removal of a latch to a "locked" position and the retention of the ratchet of lock removed. A fundamental basic idea of the invention thus resides in the absorption of a preload, especially by means of the lock ratchet. Prior loading in the sense of the invention are forces acting on a door or a window in the closed state, especially in the opening direction. Previous loads can be produced in this way for example due to wind forces acting on a door leaf, door seals or because of differences caused by weather in the case of heat, cold, humidity and deformation of the linked door thereto. Apart from this, the forces activated by people or human masses that press against a closed door and act on the door leaf are problematic, especially in case of panic. By absorbing the previous loads, the forces acting on a door leaf, respectively window, can be concentrated, respectively deflected. Ideally, the absorption of the preload is carried out after the removal of the lock ratchet in a controlled manner by a lock ratchet. This ensures that in the procedure according to the invention the interlocking system has reached a minimum closing state by means of the extracted ratchet. The absorption according to the invention of the pre-loading also makes it possible for the latch to be removed without a previous load to a "locked" position. The control according to the invention of the pre-load absorption thus allows a safe positioning where , according to the procedure, the door, respectively the window, of the interlocking system according to the invention is closed to such a point that the latch can be removed without

disturbances in the state of closing the door, respectively of the window, to a "locked" position.

By means of a post-connected retention of the extracted lock ratchet it is especially possible, in the case of a preload absorption in a controlled way by a lock ratchet, to keep the latch in the interlocked state of the interlocking system, free from prior loading, respectively. protect it against an application of previous loads. Correspondingly, an unlocking of the

interlocking system, respectively a latch recoil, from the placement of "interlocked" to the placement of "interlocked". In this way a compression of the latch can be prevented in a particularly positive manner in the placement of "interlocked", especially in a case of panic.

In the process according to the invention it is preferable that the preload is absorbed controlled by a pressure piece. According to the procedure, a preload absorption is thus provided depending on the pressure piece. The interlocking system has for this purpose at least one piece of suitable pressure, which moves according to the procedure after the removal of the lock pawl in the interlocking system in such a way that the previous load acting on the door, respectively The window is absorbed by the pressure piece and deflected. For this, it is possible, for example, to move the pressure piece appropriately towards the lock ratchet in the closed state of the door, respectively, of the window. Thus, it is essential for the invention that, for the absorption of a preload controlled by a pressure piece, the pressure piece stop, which, in order to absorb the previous load, collides with a construction piece on the side of the door, respectively of the window, especially the lock ratchet, in the direction of opening of the door, respectively of the window, is mounted in front of the latch. In this way, the process according to the invention makes it possible, in the case of a preloading application to the door, respectively to the window, a safe interlocking of the interlocking system and at the same time an especially good sealing of the door, respectively of the window.

A further aspect of the invention also lies in a method for controlling a process of unlocking an interlocking system, which comprises the backward movement of the latch to

a "unlocked" placement, the dissolution of a preload absorption on the lock ratchet and the latch-locked retention of the latch in the "locked" position. The dissolution of the preload absorption, post-connected to the backward movement of the latch in the development of time procedure,

ensures that the preload is absorbed until the latch moves to the "locked" position. In this way, an inclination of the latch in the "locking" position is especially well prevented. With this, the latch engages in the placement of "locked" in a lock-controlled manner and especially in a way

controlled by lock ratchet, that is, depending on the state of the lock and very especially on the basis of

of the lock ratchet positioning in the “unlocked” position. This special coupling of the

latch retention to the lock ensures that the latch is retained only in the case of an open door in the

placement of "interlocked" and not remain in "unlocked" state, especially in the case of non-opening

of the door. In a preferred embodiment, the method according to the invention for controlling an unlocking process presents the dissolution of a first preload absorption controlled by a pressure piece, the backward movement of a latch to a position, respectively "locked" position. ", The dissolution of a second preload absorption controlled by a lock ratchet and the retention controlled by a lock ratchet of the latch in a" locked "position. This form of

Execution to control an unlocking process thus stands out fundamentally by a staggering of two preload absorptions controlled by a pressure piece and is therefore especially suitable for example for controlling multiple interlocks. In this way, the process according to the invention makes it possible, apart from a greater thermal and acoustic attenuation of such a locking system for a door or a window, also the guarantee that the latch can move, especially in the case of panic, reliably from a "locked" placement to a "locked out" placement. This is achieved in particular by the functional cascade arrangement of the first and second preload absorption. The method according to the invention for controlling an unlocking process is thus particularly advantageous, from an economic and safety technical point of view.

The solution of the task is achieved in a particularly good way with an interlocking system according to the invention, in which the method according to the invention for interlocking an interlocking system in one of its preferred embodiments is combined with a compliant procedure. to the invention to control an unlocking process of an interlocking system. This combination according to the invention stands out for the establishment and dissolution of the at least one payload absorption to discharge the preload of the latch during an interlocking process, respectively unlocking. This ensures that the

latch, on the one hand, can move safely from its "unlocking" placement to the "interlocking" placement, so that the interlocking safety of an interlocking system according to the invention is increased. On the other hand, it is also guaranteed at the same time that the latch is unloaded from its

placement of "interlocked" until placement of "unlocked", for example in case of panic and despite the

forces exerted on the door, respectively the window, which for example are caused by a human mass that pushes against the door. Correspondingly, such a procedure is especially safe both in relation to the interlocking and in relation to the unlocking and thus brings together high handling comfort with a high safety standard in an especially elegant way.

Preferably, the backward movement of the latch until the "unlocking" position is carried out in

time-controlled form, where it is planned after a set time interval has elapsed for the case

of a latch positioning then in the placement of "locked", in which there is no

door opening, respectively window. Once the set time interval has elapsed, a re-interlocking is carried out in this way, respectively a shift of the latch to the placement of "interlocked", where there is no door opening, respectively, of a window. A backward movement of the latch as a function of time in the case of a door opening, respectively window, which has not occurred, ensures that the interlocking system is only suitable for opening for a predetermined period of time. Accordingly, it is not necessary, in this way, that a door opening really takes place for the subsequent interlocking of the interlocking system. Such a procedure for controlling an interlocking system is thus especially safe, since it is here particularly guaranteed that

the latch is not positioned permanently, by mistake, in a "unlocked" position. Of this

mode incorrect manipulations of the interlocking system only have a reduced influence on the safety of the interlocking system, controlled with the procedure according to the invention.

In the embodiments shown below, the same components are provided with them. reference symbols

According to FIGS. 1 to 7b, the interlocking system 1 with a combined opener and interlocking function has a part 2 on the side of the closing plate, respectively on the side of the fence (called to lock the latch and auxiliary ratchet). from now on unlocking 2) and a self-locking door lock 3 on the side of the door leaf (now called door lock). The guard unit 50 is integrally configured with the closing plate 5. The interlocking system 1 is installed in a door with a single wing (not shown), where the unlocking device 2 is installed in the door frame and the lock. Door 3 on the door leaf. In addition to this, the interlocking system has a tester 4, a locking plate 5, a latch 6, an auxiliary ratchet 7, a locking ratchet 8, an auxiliary ratchet pusher 9, a latch pusher 10, a ratchet recess auxiliary 11 (also designated as an auxiliary ratchet housing chamber), a release housing 12, a direct current motor 13, connections 14, a threaded rod 15, a drag python nut 16, a fixing shoulder 17, means fixing 18, guide bolts 19, control plates 20, sliding plates 21, recesses 23, torn holes 24, a tip region 25, a door lock box 27, an unlocking bolt 28, a compressor nut 29, a guard unit 50,

a lockable ratchet housing chamber 35 ’and torn holes 30.

Figure 1 refers to the interlocking state of the interlocking system 1. The latch 6 penetrates the unlocking housing 12 of the unlocking door opener 2, the auxiliary ratchet 7 collides with the auxiliary ratchet pusher 9, which is flush with its front side turned towards the door lock with the surface of the closing plate 5. The lock ratchet 8 penetrates a corresponding recess 23, arranged in the closing plate 5, located above the unlocking housing 12 of the unloader 2, located in the stop region of the lock ratchet 8 in the direction of opening the door (towards the observer) and collides with the guard unit 50. To guide the lock ratchet, sliding plates 21 are arranged. Notch 23 is connected according to the invention the guard unit, respectively the recess 23 is formed essentially by the guard unit 50.

Figure 2 is a perspective representation of the door lock 3 of Figure 1, from the side located behind in Figure 1 and not visible there. The door lock 3 has a tester 4 which, in the closed state of the door (not shown) in which the interlocking system 1 according to the invention is installed, is located in front of the closing plate 5 of the release 3 The latch 6, the auxiliary ratchet 7 and the lock ratchet 8 of the door lock 3 protrude above the surface of the tester 4, where the lock ratchet 8 is a folding ratchet, which in the extraction state it can swing parallel to the tilt plane, respectively of opening, of the door. The guard unit 50 is arranged in such a way that it acts on the lock ratchet 8 removed in the closed state of the door and penetrates the lock ratchet housing chamber 35 ’. The latch 6, the auxiliary ratchet 7 and the lock ratchet 8 are applied in such a way to the door lock 3, that these are prestressed by means of springs (not shown) and tend to extract in the direction of the unloader 2. The latch 6 can be retained in its retracted position in the door lock 3 (hereinafter called the retracted position) in the door lock 3, that is, in spite of the elastic force drive that presses the latch 6 out of the lock Door 3, latch 6 can be retained in its retracted position. The latch 6 has, in addition to this, a locking mechanism (not visible), which locks the latch 6 in the removed position, that is to say, that prevents a backward movement to the door lock. For the necessary unlocking of the latch 6, an unlocking bolt 28 is provided, driven by elastic force, which protrudes from the front side of the latch 6 away from the tester 4. This must be pressed before a backward movement of the latch 6, first in the direction of the door lock 3, to dissolve the latch lock 6 removed.

According to Figure 2, the lock ratchet 8 configured as a folding ratchet, respectively tilting, has two control surfaces, where in each case one of the control surfaces collides when opening, respectively when closing the door, with a part of the door frame or the opposite door leaf, usually with a locking plate applied there, and controls a folding ratchet overhang against the direction of tilt of the door leaf presented by the door lock. In this way, the folding ratchet is challenged in the embodiment represented in each case to such a point that the control surface of the lock ratchet 9, which is located on the side of the lock ratchet opposite the direction of tilt of the door, runs orthogonally with respect to the testera surface. This locking mechanism of the lock ratchet 8 can also be locked. In this way the lock ratchet 8 in the locked state, that is, if the lock ratchet 8 is in the rearwardly displaced position shown in Figure 1, cannot be refuted. Such a lock is activated and controlled by the auxiliary ratchet 7 pressed. Apart from this the lock ratchet 8 is arranged in such a way in the door lock 3, that the control surface of the lock ratchet 8 located in the direction of opening of the door has a smaller distance to the lateral edge of the surface of the tester 5 that the corresponding surface of the latch 6. This special arrangement ensures that, in the case of the interlocking system 1 in the locked state, as for example in figure 1, the control surface of the lock ratchet 8 located in the direction of opening of the door (in figure 1 forward and out of the drawing plane) in front of the latch 6, collides with the recess edge region correspondingly provided in the closing plate 5 to accommodate the lock ratchet 8. By this arrangement the counter-pressure exerted by the closing plate 5, with the door pressed in the opening direction, is not applied in this way on the latch or 6 but on the lock ratchet 8. The lock ratchet 8 is also movably arranged in the door lock 3 and can move in the direction of the door lock 3. With this another locking mechanism is provided, which prevents backward movement of the extracted lock ratchet. Such a blockage of the possibility of displacement of the lock ratchet 8 is also activated by an auxiliary ratchet 7 pressed.

According to Figure 2, the auxiliary ratchet 7 is cuneiformly configured. With this, the wedge forms two control bezels, which converge at the tip of the wedge. The auxiliary ratchet 7 is also prestressed by means of a spring (not shown) and can be moved, respectively, to move backwards, in the direction of the door lock 3. With this, the auxiliary ratchet 7 is designed in such a way that a movement towards both linearly in the direction of the door lock 3 and by a tilting movement, where in the case of a tilting movement the auxiliary ratchet 7 moves in the direction of the door lock 3.

The control mechanics not visible in Figure 2, which is located in a door lock box 27, controls the locking of the locking mechanism of the lock ratchet 8, the blocking of the backward movement of the lock ratchet 8 in the lock of door 3, the removal of the latch 6, the retention of the latch 6 and the locking of the latch 6. The mechanics of the door lock 3 are thereby executed in such a way that the auxiliary ratchet 7 moved backwards blocks both the mechanism of the lock ratchet 8 as a backward movement of the lock ratchet 8. Starting from the state of the door lock 7 shown in Figure 2 in the locked state, in which the latch 6 is removed and locked, and the auxiliary ratchet 7 is in a position that is already retracted to such an extent that the corresponding locking mechanisms coupled to the auxiliary ratchet 7 are activated, a desired Door interlock through I) a compressor (not shown) in effective connection with the compressor nut 29 of the door lock 3 from the inside of the door, II) through a key that fits into a lock cylinder (not shown) or III) by a panic release mechanism activated for example through a panic bar. For this, however, it is previously necessary to dissolve in each case the unlocking of the latch 6 either on the side of the lock or on the side of the closing plate.

In the opening state of the door (not shown), the latch 6 is instead held in its retracted position, the auxiliary ratchet 7 and the lock ratchet 8 are removed, the lock ratchet 8 is not locked. When the door is closed, the control bevels of the auxiliary ratchet 7 and the lock ratchet 8 are positioned relative to each other in such a way that a section is first moved back to the door lock 3 the lock ratchet 8, so general after a overflow, through one of the control surfaces of for example a closing plate. Only then the corresponding control surface of the auxiliary ratchet 7 comes into contact with the closing plate and moves backwards correspondingly. This ensures that the auxiliary ratchet 7 does not prematurely block the lock ratchet 8. The auxiliary ratchet 7 and the lock ratchet 8 then slide both on the closing plate, where the lock ratchet 8 finally falls in a corresponding recess in the closing plate and, by means of this, dissolves the retention of the latch 6, which is thus removed and locked in its extracted position. Because the auxiliary ratchet 7 remains previously in its retracted position, as shown for example in Figure 1, the locking mechanism of the lock ratchet 8 is also locked.

The unlocking of a door, which has an interlocking system according to figure 1, can also be carried out by means of a combined opener and interlocking function by means of the unlocking device 2. By means of the unlocking device 2 an unlocking and a backward movement is possible of the latch and an extraction of the auxiliary ratchet 7 in the closed state of the door. Figure 3 illustrates the locking system 1 in a corresponding state. In detail, the interlocking system 1 has a recess 11 on the side of the closing plate (hereinafter referred to as auxiliary ratchet recess 11), into which the auxiliary ratchet 7 can be introduced in the closing state of the door. The release and blocking of the auxiliary ratchet recess 11 is thereby carried out through an auxiliary ratchet pusher 11, not visible in FIG. 3. Apart from this, the unlocking device 2 has a latch pusher 10, which can dissolve the blockage. from the extracted latch 6 and can move the latch from its removed position to its retracted position. The control of the auxiliary ratchet pusher 9 and the latch pusher 10 is thereby carried out by means of a development control, which in figure 3 is surrounded by the unlocking housing 12.

Figures 4a to 7b clarify the mode of operation of the opener function of the unlocking device 2 of the interlocking system 1 according to the invention during an unlocking process.

In the side plan view on the unlocking device 2 in Figure 4a, the interlocking system is in the interlocking state. The release 2 has a closing plate 5, a first pusher 9, a second pusher 10, a housing 12, a direct current motor 13, connections 14 for the direct current motor 13, but also signal lines connecting the system for interlocking, for example, with a push-button, a threaded bar (the thread itself has not been shown), a drive python nut 16 with a guide shoulder 17, fixing means 18, guide bolts 19, 19 '(on the first pusher 9) and 19 "(on the second pusher 10), as well as two control plates 20 (not shown in Figure 4a) and 20 '.

If the interlocking system is in the locked state, the second pusher 10 is retracted in the housing 12 of the unlocking door opener 2 at least to such an extent that the door lock latch can enter the door opener of unlocking 2. The latch pusher 10 is thus configured in a solid and fundamentally parallelepiped fashion, and has two guide bolts 19 and 19 '. The two guide bolts 19 and 19 ’travel the latch pusher 10 vertically and protrude from both sides

lengths of the latch pusher 10. The longitudinal sides of the latch pusher 10 thus run orthogonally with respect to the surface of the closing plate 5 and parallel to the plane of movement of the latch pusher 10. Apart from this the two longitudinal sides are turned in each case to one of the two control plates 20 and 20 '. The auxiliary ratchet pusher 9 arranged above the latch pusher 10, on the other hand, only has one of the guide bolts 19 "running through the auxiliary ratchet pusher 9, where the longitudinal axis of the guide bolt 19" runs in parallel to the longitudinal axes of the guide bolts 19 and 19 '. Also the auxiliary ratchet pusher 9 is essentially executed in solid form, where the

front side on the side of the closing plate of the auxiliary ratchet pusher 9 is executed in such a way that the auxiliary ratchet pusher 9 fills almost completely, in its removed position shown in figure 4, the auxiliary ratchet recess 11 on the closing plate 5. Thus the surface of the front side of the auxiliary ratchet pusher 9, on the side of the closing plate, is flush with the surface of the closing plate 5.

The development control of the unlocking device 2 also shows two control plates 20 (not

visible) and 20 ’. The control plates 20 and 20 ′ are thus arranged separated from each other, so that they run

mutually in parallel and in parallel to the plane of movement of the auxiliary ratchet pusher 9 and of the latch pusher 10. Thus the plane of movement of the two pushers 9 and 10 is located between the two planes of

control panels 20 and 20 ’. To control the auxiliary ratchet pusher 9 and the latch pusher 10, the two control plates 20 and 20 'are moved along the longitudinal extension of the closure plate 5 in Figure 4a. For actuation, the unlocking device 2 has a direct current motor 13, which also has a connection socket 14 for connecting to a power supply. The DC motor 13 drives a rotary movement of the threaded rod 15 around the longitudinal axis of the threaded rod (details of the thread have not been shown), where the axis of the threaded rod runs parallel to the sheet surface. of closing. The thread is designed in such a way that it spirals around the longitudinal axis of the threaded bar. It is also an external thread, that is, the thread profile is arranged on the outer side of the threaded spindle.

The threaded bar 15 runs through a drag python nut 16, where the drag python nut 16 has a corresponding bore, which has an internal thread corresponding to the external thread of the threaded spindle 15, which engages in positive connection in shape with the external thread of the threaded bar 15. An axial rotation of the threaded bar driven by the direct current motor 13 thus ultimately leads to a displacement of the drive python nut along the longitudinal axis of the threaded bar 15. For

transmit the movement of the drag python nut 16 to the control plates 20 and 20 ’, the python nut

drag 16 has a guiding shoulder 17 that protrudes from the drag python nut 16, where in figure 3a only the guiding shoulder 17 can be seen protruding out of the plane of the drawing. The drag python nut, however, also has a corresponding guide projection on the opposite side of the drag python nut.

In order to transmit, by means of the guiding shoulder 17, the axial displacement of the drive python nut 16, relative to the threaded bar 15, the control plates 20 and 20 'have perforations, respectively, corresponding grooves, through which the guiding projection penetrates in each case as shown for example in figure 4b. In order that the control plates 20 and 20 ’can move stably and reliably along the longitudinal axis of the threaded bar 15, the release door opener 2 has, apart from this,

fixing means 18, which are also functionally linked to the control plates 20 and 20 ’. The fixing means 18 are executed as a bolt and join together the two control plates 20 and 20 ', thereby moving together with the control plates 20 and 20'. With this, the fixing means 18 are arranged orthogonally with respect to the two control plates 20 and 20 ’. The fixing means 18 and 18 'run in guides, which run along the direction of movement of the control plates 20 and 20'. In this way, for example, the guiding means

The upper part shown in Figure 4a is located on a rail guide, which runs parallel to the longitudinal axis of the threaded spindle 15.

To transmit the movement of the control plates 20 and 20 ’along the longitudinal extension of the sheet

close 5 to the auxiliary ratchet pusher 9 and the style pusher 10, the pushers 9 and 10 each have a wedge gear with control bevels. For this, the control plate 20 is provided with the torn holes 24, 24 'and 24 "and the control plate 20' with the torn holes 30, 30 'and 30", where a torn hole 24, 24' or 24 "Of the control plate 20 runs along the respective control plate 20, respectively 20 ', in each case congruent with a torn hole 30, 30' and 30" of the control plate 20 '. With this, the guide bolts 19, 19 ’and 19” are functionally attached to the control bevels, respectively to the torn holes 24 to 24 ”, respectively 30 to 30” of the control plates 20 and 20 ’. In detail the guide terminal 19 crosses with

its region protruding the torn hole 24 of the control plate 20, respectively on the opposite side the hole

torn 30 of control board 20 ’. Correspondingly, the guide bolt 19 'engages in the torn hole 24' (respectively 30 ') of the control plate 20 (respectively 20') and the guide bolt of the latch pusher 9 in the torn hole 24 "(respectively 30 ') of control board 20 (respectively

twenty'). Apart from this, the drill, through which the guide bolt 19 is guided by the latch pusher 10, is not circularly executed in longitudinal cross-section but straight. Within this bore of the bolt pusher 10 there is an excess stroke driven by elastic force, such that the bolt pusher 10 is driven by elastic force with respect to the guide bolt 19. The entire development control shown leads ultimately term that the auxiliary ratchet pusher 9 and the latch pusher 10 can be driven by the direct current motor 13. Thus the auxiliary ratchet pusher 9 and the latch pusher 10 are arranged in such a manner in the housing 12 of the unloader 2, that the latch pusher 10 executes a movement model in which first, by pressing the unlocking bolt, the locking of the latch is eliminated and then the latch is moved back to the door lock 3 until retention. In addition to this, the drive motor 13 also drives the auxiliary ratchet pusher 9, which releases or blocks the auxiliary ratchet recess 11. The development control is designed accordingly, such that the movement of the ratchet pusher auxiliary 9 and the movement of the latch pusher 10 are developed in coordination with each other, so that the locking mechanism present in the door lock 3 can be operated from the sides of the release 2.

From figures 4a to 7b, an unlocking process of the unlocking device 2 is deduced. Thus, an unlocking process of this type of the combined opener and interlocking function can be divided into four decisive positioning phases of the auxiliary ratchet pusher 9 and the pusher. of latch 10. Figures 4a to 7b show for this the mode of operation of the release 2, while the mechanism of the door lock has already been explained in detail at the beginning of the description of the figures.

In the interlocking position of the unlocking 2, respectively of the unlocking door opener according to figures 4a and 4b, the latch pusher 10 is retracted into the housing of the unlocking 2 and, thus, releases a penetration region for the latch 6 of the door lock on the release 2. The auxiliary ratchet pusher 9 on the other hand is completely removed and flush, with its front side on the side of the closing plate, with the closing plate 5. For the interlocking system this state means that with the door closed the latch 6 penetrates the unloader 2, and the auxiliary ratchet is still pressed against the door lock. The door, respectively the interlocking system 1, is thus interlocked (or).

In figures 5a and 5b the unloader is in an intermediate position. The auxiliary ratchet pusher 9, which releases or blocks the auxiliary ratchet recess 1, is still completely removed. The latch pusher 10, on the other hand, is displaced in the direction of the closing plate 5 in parallel to the closing plate 5. In this way, the unlocking bolt applied to the latch of the lock of the lock is activated in a first step. door, by this movement from the state shown in figures 4a and 4b to the state shown in figures 5a and 5b, such that the latch lock has been canceled. Next, the latch 6 has been moved out of the housing 12 of the unlocking device 2, at least partially, by means of the latch pusher 10 moved in the direction of the closing plate 5. Up to this point the latch pusher 10 has moved with it linearly. Such a movement is made possible by torn holes 24 and 24 '(respectively, correspondingly to this, the corresponding torn holes in the control board 20'), which run

mutually in parallel but transversely to the longitudinal axis of the threaded spindle 15. With this the movement of the latch pusher 10 has been performed orthogonally with respect to the direction of travel of the plates

control 20 and 20 ’.

Figures 6a and 6b depict the unloader 2 hereinafter in a position, in which the latch has completely moved out of the housing 12 of the unloader 2. The latch pusher 10 has no longer moved linearly here, but which has swung out of the release 2, beyond the closing plate surface, with the end of the latch pusher 10 turned towards the direct current motor 13. With this in figure 6a the tip region 25 can be recognized, protruding out of the door opener housing 12, from the latch pusher 10 configured as a tilting pusher. The swinging movement is

achieved by the special path of the torn holes 24 and 24 ’(respectively, of the corresponding torn holes on the control board 20’). Such a tilting movement is controlled by the control plates 20 and 20 ', where the control bevels of a guide bolt, in the present embodiment of the guide bolt 19', run parallel to the longitudinal axis of the threaded bar 15, while the control bevel of the guide bolt 19 of the auxiliary ratchet pusher 9 runs obliquely with respect to the longitudinal axis of the threaded spindle 15.

In Figures 7a and 7b, finally, the auxiliary ratchet pusher 9 configured as a thrust pusher, respectively linear, is moved to its retracted position in the housing 12 of the unloader 2, thereby releasing the auxiliary ratchet recess 11 The position shown of the two pushers 9 and 10, one with respect to the other, corresponds to the unlocking state of the interlocking system 1 according to the invention. The auxiliary ratchet 7 of the door lock opposite the closing plate can penetrate the auxiliary ratchet recess 11, whereby the lock of the lock ratchet is canceled and latch retention is activated. Apart from this, by means of the position shown in figures 7a and 7b of the two pushers, a "permanent opening function" of the locking system 1 can also be achieved. By closing the door the auxiliary ratchet does not remain continuously displaced towards back, but with the door closed it can penetrate the auxiliary ratchet recess 11, the locking mechanism of the door lock 3 is not activated. For this purpose, the auxiliary ratchet 7 is applied in relation to each other. 8 ratchet ratchet and rebates

corresponding on the side of the closing plate, which at least during the “permanent opening function” to the

close the door the lock ratchet 8 does not fall on the closing plate 5 until after the auxiliary ratchet 7.

Figures 8 to 16 illustrate the mode of operation of another guard unit 31 of an interlocking system 1 with a combined opener and interlocking function, which can be used to realize the combined opener and interlocking function in combination, for example, with an unloader. of Figures 1 to 11. The guard unit 31 is a door opener module for controlling the lock ratchet on the fence side and illustrates a preferred embodiment of an opener and interlocking function according to the invention with a fixing installation. Thus, the guard unit 31 is combined, for example, with the unlocking device 2 and the self-locking door lock 3, in order to provide the combined function of opener and unlocking according to the invention of the interlocking system according to the invention. In particular, the unlocking device 2 and the guard unit 31 can be configured for this, for example, modularly but also as a compact unit.

The guard unit 31 has, according to figures 8 to 16, a lock plate 5 ', a lock ratchet 8', a direct current motor 13 ', connections 14', a housing 32, a ratchet pusher of lock 33, a pressure piece 34, a lock ratchet housing chamber 35, control plates 36 and 36 ', torn holes 37 and 37', a control pivot 38, a lock ratchet recess 39, a plate of pressure piece control 40, a torn hole 41, which is functionally engaged with control pivot 38, and a pressure piece bearing 42.

According to Figure 9, the guard unit 31 has a housing 32 on which the metal plate is screwed.

close 5 ’. The closing plate 5 ’runs along the door frame (not shown) and can be configured

for example, forming a part with the closing plate 5 of the unlocking device 2. A recess is provided in the housing 32, through which cables can be guided, for example for the power supply and / or for the transmission of signals to the connection 14 '. On the side of the door leaf a door lock is located in front of the closing plate, such that the lock ratchet 8 ’of the door lock, in the state of

When closing the door, it can engage through the lock ratchet recess 39 in the lock ratchet housing chamber 35 of the guard unit 31. For clarity in figures 8 to 10 only

indicated the 8 ’lock ratchet on the side of the door leaf. In the ratchet housing chamber of

lock 35 is arranged a lock ratchet pusher, which can press out of the chamber

lock ratchet housing 35, in the lock direction, the lock ratchet 8 ’in the state

of closing the door. The lock ratchet pusher 35 is in figure 8 in its retracted position and releases

the lock ratchet housing chamber 35 for engaging the lock ratchet 8 ’according to the

Figure 9 (in the direction of the arrow).

Figure 9 refers correspondingly to the state of the closure system, which is connected to Figure 8, in the

that the lock ratchet 8 ’has moved in the arrow direction of figure 1 and engages in the chamber of

lock ratchet 35. According to figure 9 the door (not shown) of the interlocking system is

closed and the lock ratchet 8 ’is functionally engaged with the lock ratchet housing chamber 35. The door (not shown) cannot therefore be pushed into this" interlocking "state.

According to Figures 10a and 10b, a pressure piece 34 moves against the opening direction D of the door, towards the lock ratchet, and thus presses the lock ratchet together with the door leaf in the direction of closing E. In this way it is possible to suppress an existing lock ratchet clearance, it is

say the freedom of movement of the lock ratchet 8 ’in the lock ratchet housing chamber

35. In this way it is possible to press the door in the closed state against a joint on the side of the fence, for example for acoustic and thermal attenuation purposes, in the closing direction E, respectively against the opening direction D of the door leaf. The pressure piece 34 of the tilting part type moves, respectively, tilts, for this to the lock ratchet housing chamber 35 according to the arrow A and collides, relative to the movement of the lock ratchet, laterally with the lock ratchet and finally presses the lock ratchet (and with it also the door lock presented by the lock ratchet, respectively the door leaf presenting the door lock [not shown in each case]) in the direction of the fence of door (address E) with shutter (not shown). The pressure piece 34 thus makes it possible to improve the sealing characteristics of the combined opener and interlocking function according to the invention.

In detail the pressure piece 34 is parallelepipedic and has a homogeneous thickness. In the partial region back

towards the lock ratchet 8 ', the pressure piece has a stop region which, during the fixation of the lock ratchet 8' that penetrates the lock ratchet housing chamber, collides with the lock ratchet and through the which facilitates the contact of ratchet of lock in the side of the piece of pressure, respectively which for the process of tightening is in contact with the ratchet of lock. This stop region is ultimately responsible also for the absorption of preload according to the invention.

In addition to this, the pressure piece 34 absorbs, by functionally pre-assembled positioning in the opening direction D, previous loads that are transmitted from the door leaf to construction parts of the

interlocking system, and diverts them to the guard unit 31, since the lock ratchet 8 ’in the

The opening direction D of the door first collides with the pressure piece 34. The latches, auxiliary ratchets, etc., available if necessary in the interlocking system 1, are thus discharged correspondingly from previous loads of this type.

To control the pressure piece 34 and the lock ratchet pusher 33, the guard unit 31 has

control plates 36 and 36 ’, which in each case have control bevels in the form of torn holes 37 and 37’. In particular, the control of the lock ratchet pusher through the control plates 36 and 36 'is carried out in a manner comparable to the control of the auxiliary ratchet pusher 9 and the latch pusher 10 of the unloader 2 according to figures 1 to 7b . To control the pressure piece 34, a pressure piece control plate 40 is also provided, which for the control of the pressure piece has a control bevel in the form of the torn hole 41. The operation of the control plates 36, 36 'and 40 is carried out, according to figures 11 and 12, through a direct current motor 13' and a threaded spindle. The basic arrangement of the control plates 36 and 36 'is comparable to the arrangement of the control plates 20 and 20' of the unloader 2. For stabilization purposes, the control plates 36 and 36 'are connected to each other through a bridge element.

According to figures 13, 14 and 15, to open the door it is required to loosen the pressure piece and move the lock ratchet 8 ’out of the lock ratchet housing chamber 35, according to figures 13, 14 and

15. To clarify this development, the lock ratchet 8 ’cannot be seen in figures 13, 14 and 15. In the state

Initially according to Figure 13, the lock ratchet penetrates the lock ratchet housing chamber 35 and is pressed by the pressure piece 34 against the direction of opening of the door. The pressure piece 34 is inserted laterally into the lock ratchet housing chamber 35. The lock ratchet pusher 33 is in its retracted position, so that the chamber of

lock ratchet housing 35 is released for engagement of lock ratchet 8 ’.

In order to open the door, a discharge passage is thus carried out in this way, by means of which the pressure piece 34 is extracted laterally from the lock ratchet housing chamber 35. For this, the control plates 36, 36 'are guided. and 40 along the fence using the DC motor. In this way, a previous preload absorption of forces acting on the door leaf is dissolved by the pressure piece 34.

After the dissolution of the preload absorption, respectively of the application of the pressure piece to the lock ratchet by the pressure piece 34, by a further displacement of the plates

control 36 and 36 ’, the lock ratchet pusher 33 presses the lock ratchet out of the

lock ratchet housing chamber 35, respectively locks this for a functional gear. Then you can open the door by pushing it.

The fragmentary representation according to Figure 16 of the modular guard unit 31 clarifies the control of the pressure piece 34. The pressure piece control plate 40 is connected to the pressure piece 34 with the torn hole 41. The part construction formed by the pressure piece 34 and the pressure piece control plate 40 is arranged in the guard unit 31, so that it can move through the pressure piece bearing 42. To control the movement development of the pressure piece 34, respectively of the pressure piece control plate 40, the pressure piece control plate has the torn hole 41, into which the

control pivot 38, which is arranged in the construction piece that bridges control plates 36 and 36 ’. By means of a displacement along the fence, by means of the direct current motor 13 ’of the control plates 36 and 36’, the control pivot 38 slides along the torn hole 41 and thus controls the

positioning of the pressure piece 34 in the lock ratchet housing chamber 35.

Mutual relations in the opening direction D and in the closing direction E of the movement developments

of the pressure piece 34 (arrows A and A '), of the lock ratchet pusher 33 (arrows B and B'), of the control plates 36 and 36 '(arrows C and C') and of the blade Door with door lock, which has the lock ratchet 8 (direction of the closing movement in the closing state of the closing system indicated by the arrow in Figure 8), are indicated in particular in Figures 8 and 16. Figures 15 and 16 summarize the

directions of movement for a better understanding and reproduce the possibility of tilting movement A 'of the pressure piece and especially also the linear movement B' of the lock ratchet pusher 30, orthogonally with respect to the linear movement C 'of the control plates 36 and 36 'along the gate fence.

In the sequence of Figures 13, 14 and 15, an unlocking process is indicated in a time course, in which the arrows in continuous line A, B and C refer to the movements of the pressure piece 34 (arrows A ),

of the lock ratchet pusher 38 (arrows B) and of the control plates 36 and 36 ’(arrows C). The linear movement of the control plates 36 and 36 'according to Figure 13, at the beginning of the unlocking process, correspondingly controls first the dissolution of the lock ratchet fixation (not shown) in the ratchet housing chamber lock 35 by means of the pressure piece 34. For this, the pressure piece swings out of the lock ratchet housing chamber 35. After tilting out the pressure piece 34, the lock ratchet pusher 33 presses the lock ratchet (not shown) in the direction of the door lock out of the lock ratchet housing chamber 35, where this movement is controlled again by continuing the movement of the control plate in the direction C The lock ratchet pusher thus dissolves the lock ratchet gear into the lock ratchet housing chamber. to 35. The closing system is finally according to figure 15 in the "unlocked" state, the door can be pushed.

5 In the sequence of Figures 15, 14 and 13, an interlocking process is indicated in a time course, where the dashed arrows A, B and C refer to the movements of the pressure piece 34 (arrows A ), of the

lock ratchet pusher 38 (arrows B) and control plates 36 and 36 ’(arrows C). The control plates 36 and 36 'move for this first linearly along the door fence (arrow C), such that 10 in a linear motion (arrow B) that develops orthogonally with respect to this thrust direction, the lock ratchet pusher 33 is engaged in the direction of the lock ratchet base of the lock ratchet housing chamber 35, whereby the lock ratchet housing chamber 35 is released for engagement of a ratchet lock (not shown). If the movement continues in the direction C of the control plates 36 and 36 'according to figure 14 (the lock ratchet that engages 15 in the lock ratchet housing chamber is not shown), a tilt is finally activated of the pressure piece 34 into the lock ratchet housing chamber for fixing the lock ratchet in the direction of the arrow A. The pressure piece 34 is thus a tilting part, which is configured to form a piece with the pressure piece control plate 40. The lock ratchet, previously provided with a clearance relative to the lock ratchet housing chamber 35, is fixed to

20 corresponding form after the complete development of the closing process according to figure 13 (and correspondingly to this figures 10a and 10b) in the lock ratchet housing chamber 35, at least in the opening and closing direction D / E of the door leaf that supports the door lock with lock ratchet.
