Definitions
- the invention relates to an electrically releasable release device according to the preamble of claim 1 for doors, which is suitable for installation in door frames of single-leaf doors or in the passive leaf of double-leaf doors, the doors are equipped with a lock, which has a trap.
- Electrically actuated release devices for doors are well known. They serve as a door opener for switching or unlocking doors. In this case, they generally have an armature that can be actuated by an electrically controllable coil.
- a latch is held in a locking position by means of a spring-loaded hinged armature which is mounted at one end in a housing, which is also rotatably mounted at one end in the housing and is in engagement with the case of the door opener.
- the case is also spring-loaded and mounted pivotably in the housing. If such an electromagnet is actuated, the hinged armature is tightened, and the bolt is released.
- Folding anchors have the disadvantage that by appropriate hitting or shaking the door such an electromagnetic door opener can be opened without energization. This is based on the fact that with appropriate vibrations of the hinged armature performs pivotal movements. At the same time Pressure against such a door can dodge the latch case as soon as the hinged armature releases the attacking on the case latch due to the shocks briefly. The safety function of a door opener with a hinged armature is therefore not always guaranteed.
- the U.S. 3,638,984 shows a door opener in which a pawl with a lever, on one arm of which a roller is arranged cooperates. Such a role obviously fulfills the task that a jamming of the pawl against a locking lever is reduced.
- a general locking device for emergency exit doors with a wall and a frame side attachable electromagnetically acting locking unit and a side mountable ferromagnetic anchor plate shows the DE 100 50 111 C1 .
- An electrically switchable locking device as used for windows or doors, discloses the DE 196 17 151 A1 .
- a switching contact is provided, which reports the locking state of the door.
- the actuation of the switching contact is realized via a contact pin.
- a quiescent current door opener which is equipped with a pivotally mounted in its housing case and lockable with interlocking stop surfaces provided lever members and releasably includes, can be taken from DE-GM 75 32 907.
- pressurizing traps can then come about when, for example, a person presses against the door and the door opener has not yet been operated.
- Such a door opener can therefore not be installed in escape and rescue routes, since in a panic corresponding to the people who want out of a building, pressure against a door can be triggered to open them.
- an electromagnetically operated door opener which includes a panic function for single or double leaf doors.
- Different locking elements are coupled via appropriate toggle lever with spokes and the armature of a solenoid in such a way that the vortexe latch and the bolt will hold the applied magnets at a quiescent current.
- a release is effected, in which the energy stored in a spring pulls the armature out of the lifting magnet and transfers it via a mechanical coupling into a release position.
- DE 39 42 379 A1 is to take a closing device, in which an armature of an electromagnet is loaded by springs loaded displaceable and at the same time causes a blocking of a pawl in non-energized electromagnet.
- an electromechanically controlled door opener operates in the EP 0 278 359 B1 is disclosed.
- the DE 297 18 378 U1 further shows a locking device for a lock in which the armature of an electromagnet is forcibly guided within a guide bore.
- a first anchor part is when creating a electrical voltage to a coil attracted by this and moved to a blocking position.
- the first anchor part is operatively connected by means of a connecting rod with a second anchor part.
- the second anchor member When tightening the first anchor member by means of the coil, the second anchor member is also pivoted in a locking position. In the blocking position, mutually facing surfaces of the second anchor part and a locking lever or a pin of a pawl press against each other.
- the first anchor member is urged by means of a spring in an unlocked position.
- the second anchor part is pivoted away from the locking lever or pin.
- the first anchor part is U-shaped.
- a release device specified in claim 1 can be achieved that such a release device can be arranged in any mounting position. Also, as will be described below, such a release device is able to release a pressurized pawl even if the release device, which operates on the principle of quiescent current, is not energized.
- the release device comprises a locking lever and an electromagnet with an armature and a coil.
- the locking lever has a blocking surface and a contact surface. Upon pivoting of the pawl in the direction of the contact surface strikes Projection of the pawl on the contact surface and engages with it.
- the blocking surface is formed on a side facing away from the pawl of the locking lever. In a blocking operating position in which the coil is energized, the armature is moved towards the blocking surface due to a magnetic force of the coil.
- On a fork a locking roller or a spring-loaded wedge is arranged. The fork is formed on a locking lever facing the end of the free leg of the armature. In an unlocking operating position in which the coil is not energized, the armature is urged away from the blocking surface by means of a spring element. In this case, the projection can be disengaged from the contact surface.
- the locking surface of the locking lever cooperates both with the rotatably mounted locking roller and with the corresponding spring-loaded wedge, which is located on a leg of the armature.
- the armature When current is applied to the coil, the armature is pulled forward in a locking direction which does not allow the locking lever to effect a release of the locking pawl. In this position, the locking surface bears against the wedge or on the locking roller and thus can not be pivoted due to the locking lever mounted on one side. Only at a current release position of the armature would this pushed away due to the return spring of the yoke of the coil and thus moved in a release direction.
- This stroke causes the locking surface no longer press against the locking roller or the like, and thus the locking lever can be pushed over the locking roller or the wedge due to the force exerted on the pawl against a spring located on the locking lever. If the pawl is pivoted, then the case of the lock can pass the pivoted pawl of the release device.
- the free legs of the armature wrap around the coil of the electromagnet.
- the anchor is according to the invention on or in a housing of Spool guided stored. Guide means are provided on both the armature and the solenoid to allow axial movement of the armature to the coil.
- the coil is fixed in the bottom of a housing of the release device.
- the guide device is designed so that on the inner sides of the legs of the armature guide tracks are present, which cooperate with counter bearings, which are located below the coil. Such a construction ensures that the anchor can not fall out of the housing when installed.
- the anchor is attached to no other points and is thus slidably mounted only below the coil; while the anchor is spring loaded.
- One of the spring bearings causes in a Saltbestromung the coil that a central part, which connects the two legs of the armature is loaded with two springs, so that the armature can be pushed out by a locking lever in a release direction. Further, a spring pushes the armature in the opposite direction.
- the sliding guides can also be coated with a high-performance ceramic.
- a high-performance ceramics consists z. B. of the finest ceramic particles that are only a few millionths of a millimeter in size. The ceramic particles are used in a chemical substance by a sol-gel process. A resulting material may, for. B. applied by spraying and retains its ceramic properties and get new ones that include a new ability. This new ability is characterized z. B. by very good sliding properties.
- the locking lever In order to perform a precise adjustment of the locking lever, it can be mounted eccentrically, for example, at its one-sided pivot point. By a rotation of the eccentric thus the engagement point and thus the release point of the blocking surface are changed.
- an armature 1 and an associated coil 2 for an electrically releasable release device 26 is shown for a door.
- the armature 1 is formed according to the invention U-shaped and has two free legs 4 and 5. On the two legs 4 and 5 guideways 8 are arranged, with which the armature 1 can be guided on or under the coil 2 slidably.
- a sliding coating 18 is preferably provided on the guideways 8 of the U-shaped armature 1 and on the abutments 12 of the coil 2 and on a bottom 54 of a housing 28 of the release device 26.
- the z. B. may consist of a high performance ceramic, the armature 1 can be moved in the housing 28 of the release device 26 against the abutment 12 on the spool 2 with a very low coefficient of friction. By reducing the frictional forces and the performance of the coil 2 can be reduced, which means a reduction in power consumption and thus allows a smaller size of a release device 26 according to the invention.
- the one leg 5 of the U-shaped armature 1 carries a fork 19, which is penetrated by an axis 7, on which a locking roller 6 is mounted.
- a blind hole spring chamber 21 is arranged, which extends axially parallel to the leg 5 and serves to receive a spring 10.
- a substantially centrally arranged roller 25 is mounted on the leg 5.
- a spring-loaded wedge can be used.
- the other leg 4 of the U-shaped armature 1 is provided with two each formed as a blind hole spring chambers 22, 23 which are arranged lying on a common axis one behind the other and aligned axially parallel to the leg 4. These spring chambers 22, 23 serve to receive two springs 16, 17 (see FIGS. 6 and 7 ). Furthermore, four rollers 24 may be mounted on the leg 4, which, like a Roller 25 on the leg 5, with its outer periphery slightly beyond the outer contour of the leg 4 survive (see. FIG. 11 ). The rollers 24 and 25 are used when the sliding coating 18 is not used to reduce the friction coefficient.
- a remanence pin 9 is mounted, which is arranged substantially centrally in a middle part 20 connecting the two legs 4, 5 and projecting in the direction of the free ends of the legs 4, 5 into the interior of the U-shaped armature 1 (cf. , Figures 5 and 14 ) and is loaded with a leaf spring, not shown.
- the coil 2 In the space enclosed by the two legs 4, 5 space, the coil 2 is mounted.
- the coil 2 consists of a housing 15, on which two guide surfaces are formed as an abutment 12 to the guideways 8. This makes it clear that the armature 1 is quasi designed as a slide and is pulled against the coil 2 when the coil 2 is energized. As restoring forces serve the springs 16, 17 and 10. By this construction, the armature 1 is forcibly guided on the two-sided thrust bearings 12, which also defines a stable mounting position.
- a bobbin with winding 14 is mounted in the housing 15, a bobbin with winding 14 is mounted.
- the bobbin 14 is provided with a central opening in which a spool core 13 is seated.
- the bobbin 14 is further provided on the outwardly facing side with terminals 3 for a power supply.
- a coil attachment 11 with which the housing 15 can be attached to or in the housing 28.
- the housing 15 of the coil 2 is wholly or partly made of a ferromagnetic material; also the anchor 1.
- the locked release device 26 is reproduced, which means that the armature 1 in a locking direction 32, due to Magnetic forces generated by the coil 2 has been pulled.
- the springs 10 support the magnetic forces of the coil 2.
- a locking surface 48 of a locking lever 33 at.
- the locking lever 33 is rotatably supported on one side at its opposite end of the locking surface 48 via a rotation axis 46.
- a blind bore 38 in which a spring 37 is immersed and the other end is supported against a wall of the housing 28.
- the axis of rotation 46 can, as in the FIG. 4 is shown to be formed as an eccentric 53, so as to effect a continuous adjustment of the locking lever 33 can.
- On the opposite side of the blind bore 38 is located on the locking lever 33, a contact surface 45 which cooperates with a projection 36 of the pawl 35.
- the pawl 35 which is rotatably supported via axles 44, can not be pivoted, because the locking lever 33 prevents this.
- FIG. 1 Indentations 30 and 40 can be seen at the ends of the housing 28 in which terminal strips 29 and 39 are provided, which are required for both the electrical supply of the coil 2 and for the messages of the switches 41 and 42. Also located in the housing 28 holes 34 to connect a corresponding strike plate and thus ensure the installation of the release device 26.
- FIG. 2 shows the state in which the armature 1 is pressed in a release direction 31 due to the non-occurring energization of the coil 2 due to the spring 16.
- the springs 10 are compressed at the moment in which the locking lever 33 is pivoted by the pawl 35.
- the blocking surface 48 can be pressed past the roller 6.
- a role is also here a reduction of a coefficient of friction between locking surface 48 and roller 6 causes.

Description
Die Erfindung betrifft eine elektrisch entsperrbare Freigabevorrichtung nach dem Oberbegriff des Anspruchs 1 für Türen, die zum Einbau in Türrahmen von einflügeligen Türen oder im Standflügel von zweiflügeligen Türen geeignet ist, wobei die Türen mit einem Schloss, das eine Falle aufweist, ausgestattet sind.The invention relates to an electrically releasable release device according to the preamble of
Elektrisch betätigbare Freigabevorrichtungen für Türen sind hinlänglich bekannt. Sie dienen als Türöffner zum Schalten bzw. Entsperren von Türen. Dabei weisen sie im Allgemeinen einen Anker auf, der von einer elektrisch ansteuerbaren Spule betätigt werden kann. Bei derartigen elektromechanischen Türöffnern wird mittels eines federbelasteten Klappankers, der an einem Ende in einem Gehäuse gelagert ist, ein Riegel in einer Sperrstellung gehalten, der ebenfalls an einem Ende im Gehäuse drehbar gelagert ist und mit der Falle des Türöffners im Eingriff steht. Die Falle ist dabei ebenfalls federbelastet und im Gehäuse verschwenkbar gelagert. Wird ein solcher Elektromagnet betätigt, so wird der Klappanker angezogen, und der Riegel wird dabei freigegeben. Bei einem entsprechenden Druck gegen die Tür wird aufgrund der vorstehenden Schlossfalle ein Verschwenken des freigegebenen Riegels der Tür bewirkt. Klappanker haben den Nachteil, dass durch entsprechendes Schlagen oder Rütteln an der Tür ein solcher elektromagnetischer Türöffner ohne Bestromung geöffnet werden kann. Dieses beruht darauf, dass bei entsprechenden Erschütterungen der Klappanker Schwenkbewegungen ausführt. Bei gleichzeitigem Druck gegen eine solche Tür kann dabei die Schlossfalle ausweichen, sobald der Klappanker aufgrund der Erschütterungen den an der Falle angreifenden Riegel kurzzeitig freigibt. Die Sicherheitsfunktion eines Türöffners mit einem Klappanker ist daher nicht immer gewährleistet.Electrically actuated release devices for doors are well known. They serve as a door opener for switching or unlocking doors. In this case, they generally have an armature that can be actuated by an electrically controllable coil. In such electromechanical door openers, a latch is held in a locking position by means of a spring-loaded hinged armature which is mounted at one end in a housing, which is also rotatably mounted at one end in the housing and is in engagement with the case of the door opener. The case is also spring-loaded and mounted pivotably in the housing. If such an electromagnet is actuated, the hinged armature is tightened, and the bolt is released. With a corresponding pressure against the door, a pivoting of the released latch of the door is effected due to the protruding latch. Folding anchors have the disadvantage that by appropriate hitting or shaking the door such an electromagnetic door opener can be opened without energization. This is based on the fact that with appropriate vibrations of the hinged armature performs pivotal movements. At the same time Pressure against such a door can dodge the latch case as soon as the hinged armature releases the attacking on the case latch due to the shocks briefly. The safety function of a door opener with a hinged armature is therefore not always guaranteed.

Einen Ruhestromtüröffner, der mit einer in seinem Gehäuse schwenkbar gelagerten Falle ausgestattet ist und mit ineinander greifenden Anschlagflächen versehene Hebelglieder sperr- und lösbar beinhaltet, ist aus der DE-GM 75 32 907 zu entnehmen. Es besteht bei derartigen Ruhestromtüröffnern die Gefahr, dass bei einem Stromausfall die Tür dann nicht betätigt werden kann, wenn sie gleichzeitig druckbeaufschlagt ist. Dabei können derartige druckbeaufschlagende Fallen dann zustande kommen, wenn beispielsweise eine Person gegen die Tür drückt und der Türöffner noch nicht betätigt worden ist. Ein solcher Türöffner kann deshalb in Flucht- und Rettungswegen nicht angebracht werden, da bei einer Panik entsprechend von den Personen, die aus einem Gebäude heraus wollen, Druck gegen eine Tür ausgelöst werden kann, um diese zu öffnen.A quiescent current door opener, which is equipped with a pivotally mounted in its housing case and lockable with interlocking stop surfaces provided lever members and releasably includes, can be taken from DE-GM 75 32 907. There is the danger in such quiescent door openers that in the event of a power failure the door can not then be actuated if it is pressurized at the same time. there Such pressurizing traps can then come about when, for example, a person presses against the door and the door opener has not yet been operated. Such a door opener can therefore not be installed in escape and rescue routes, since in a panic corresponding to the people who want out of a building, pressure against a door can be triggered to open them.

Es ist Aufgabe der vorliegenden Erfindung, eine elektrisch betätigbare und damit entsperrbare sowie klein bauende Freigabevorrichtung zu schaffen, die in jeder beliebigen Einbaulage einsetzbar ist, bei der die zu benutzende Tür auch unter Druck immer geöffnet werden kann.It is an object of the present invention to provide an electrically actuated and thus unlockable and small-sized release device that can be used in any mounting position in which the door to be used can always be opened under pressure.
Gelöst wird diese Aufgabe durch die im Patentanspruch 1 angegebenen Merkmale. Vorteilhafte Ausgestaltungen des Gegenstandes des Patentanspruches 1 ergeben sich aus den Unteransprüchen.This problem is solved by the features specified in
Mit einer im Patentanspruch 1 angegebenen Freigabevorrichtung lässt sich erreichen, dass eine solche Freigabevorrichtung in beliebigen Einbaulagen angeordnet werden kann. Auch, wie nachfolgend noch beschrieben wird, ist eine derartige Freigabevorrichtung in der Lage, eine unter Druck stehende Sperrklinke auch dann noch freizugeben, wenn die Freigabevorrichtung, die nach dem Ruhestromprinzip arbeitet, nicht bestromt wird.With a release device specified in
Die Freigabevorrichtung weist einen Sperrhebel und einen Elektromagneten mit einem Anker und einer Spule auf. Der Sperrhebel weist eine Sperrfläche und eine Anlauffläche auf. Bei einem Verschwenken der Sperrklinke in Richtung der Anlauffläche schlägt ein Vorsprung der Sperrklinke an der Anlauffläche an und gelangt mit ihr in Eingriff. Die Sperrfläche ist an einer der Sperrklinke abgewandten Seite des Sperrhebels ausgebildet. In einer Sperr-Betriebslage, in der die Spule bestromt wird, wird der Anker aufgrund einer Magnetkraft der Spule zu der Sperrfläche hin bewegt. An einer Gabel ist eine Sperrrolle oder ein federbelasteter Keil angeordnet. Die Gabel ist an einem dem Sperrhebel zugewandten Ende eines der freien Schenkel des Ankers ausgebildet. In einer Entsperr-Betriebslage, in der die Spule nicht bestromt wird, wird der Anker mittels eines Federelements von der Sperrfläche weg gedrängt. In diesem Fall kann der Vorsprung mit der Anlauffläche außer Eingriff gelangen.The release device comprises a locking lever and an electromagnet with an armature and a coil. The locking lever has a blocking surface and a contact surface. Upon pivoting of the pawl in the direction of the contact surface strikes Projection of the pawl on the contact surface and engages with it. The blocking surface is formed on a side facing away from the pawl of the locking lever. In a blocking operating position in which the coil is energized, the armature is moved towards the blocking surface due to a magnetic force of the coil. On a fork, a locking roller or a spring-loaded wedge is arranged. The fork is formed on a locking lever facing the end of the free leg of the armature. In an unlocking operating position in which the coil is not energized, the armature is urged away from the blocking surface by means of a spring element. In this case, the projection can be disengaged from the contact surface.
Sowohl mit der drehbar gelagerten Sperrrolle als auch mit dem entsprechend federbelasteten Keil, die bzw. der sich an einem Schenkel des Ankers befindet, wirkt somit erfindungsgemäß die Sperrfläche des Sperrhebels zusammen. Bei einer Bestromung der Spule wird der Anker in eine Sperrrichtung vorgezogen, die es dem Sperrhebel nicht erlaubt, eine Freigabe der Sperrklinke zu bewirken. In dieser Position liegt die Sperrfläche an dem Keil oder an der Sperrrolle an und kann somit aufgrund des einseitig gelagerten Sperrhebels nicht verschwenkt werden. Erst bei einer Stromlosstellung des Ankers würde diese aufgrund der Rückstellfeder von dem Joch der Spule weggedrückt und somit in eine Freigaberichtung bewegt. Dieser Hub bewirkt, dass die Sperrfläche nicht mehr gegen die Sperrrolle oder dergleichen andrückt, und es kann somit der Sperrhebel aufgrund der über die Sperrklinke ausgeübten Kraft gegen eine an dem Sperrhebel befindliche Feder über die Sperrrolle oder den Keil hinweg gedrückt werden. Wird die Sperrklinke verschwenkt, so kann die Falle des Schlosses an der verschwenkten Sperrklinke der Freigabevorrichtung vorbeigehen.Thus, according to the invention, the locking surface of the locking lever cooperates both with the rotatably mounted locking roller and with the corresponding spring-loaded wedge, which is located on a leg of the armature. When current is applied to the coil, the armature is pulled forward in a locking direction which does not allow the locking lever to effect a release of the locking pawl. In this position, the locking surface bears against the wedge or on the locking roller and thus can not be pivoted due to the locking lever mounted on one side. Only at a current release position of the armature would this pushed away due to the return spring of the yoke of the coil and thus moved in a release direction. This stroke causes the locking surface no longer press against the locking roller or the like, and thus the locking lever can be pushed over the locking roller or the wedge due to the force exerted on the pawl against a spring located on the locking lever. If the pawl is pivoted, then the case of the lock can pass the pivoted pawl of the release device.
Die freien Schenkel des Ankers umschlingen quasi die Spule des Elektromagneten. Der Anker ist erfindungsgemäß an bzw. in einem Gehäuse der Spule geführt gelagert. Sowohl an dem Anker als auch an dem Elektromagneten sind Führungseinrichtungen vorhanden, die eine axiale Bewegung des Ankers zu der Spule ermöglichen. Die Spule ist dabei im Grund eines Gehäuses der Freigabevorrichtung befestigt. Die Führungsvorrichtung ist so gestaltet, dass an den inneren Seiten der Schenkel des Ankers Führungsbahnen vorhanden sind, die mit Gegenlagern, die sich unterhalb der Spule befinden, zusammenwirken. Durch eine solche Konstruktion ist sichergestellt, dass im Einbau-Zustand der Anker nicht aus dem Gehäuse herausfallen kann. Der Anker ist an keinen weiteren Punkten befestigt und ist somit nur unterhalb der Spule verschiebbar gelagert; dabei ist der Anker federbelastet. Eine der Federlagerungen bewirkt bei einer Nichtbestromung der Spule, dass ein Mittelteil, welches die beiden Schenkel des Ankers verbindet, mit zwei Federn belastet ist, damit der Anker durch einen Sperrhebel in eine Freigaberichtung heraus gedrückt werden kann. Ferner drückt eine Feder den Anker in entgegengesetzte Richtung.The free legs of the armature wrap around the coil of the electromagnet. The anchor is according to the invention on or in a housing of Spool guided stored. Guide means are provided on both the armature and the solenoid to allow axial movement of the armature to the coil. The coil is fixed in the bottom of a housing of the release device. The guide device is designed so that on the inner sides of the legs of the armature guide tracks are present, which cooperate with counter bearings, which are located below the coil. Such a construction ensures that the anchor can not fall out of the housing when installed. The anchor is attached to no other points and is thus slidably mounted only below the coil; while the anchor is spring loaded. One of the spring bearings causes in a Nichtbestromung the coil that a central part, which connects the two legs of the armature is loaded with two springs, so that the armature can be pushed out by a locking lever in a release direction. Further, a spring pushes the armature in the opposite direction.
Damit der Anker zwischen dem Gehäuse der Spule und dem Boden der Freigabevorrichtung keine große Reibung hervorruft, sind diese Bereiche mit einer Gleitführung ausgestattet. Darüber hinaus können die Gleitführungen auch mit einer Hochleistungskeramik beschichtet sein. Eine solche Hochleistungskeramik besteht z. B. aus feinsten Keramikpartikeln, die nur wenige Millionstel Millimeter groß sind. Dabei werden die Keramikpartikel in einer chemischen Substanz nach einem Sol-Gel-Verfahren verwendet. Ein daraus entstehendes Material kann z. B. im Sprühverfahren aufgebracht werden und behält seine keramischen Eigenschaften und bekommt neue hinzu, die eine neue Fähigkeit beinhalten. Diese neue Fähigkeit zeichnet sich z. B. durch sehr gute Gleiteigenschaften aus.In order for the armature between the housing of the coil and the bottom of the release device does not cause great friction, these areas are equipped with a sliding guide. In addition, the sliding guides can also be coated with a high-performance ceramic. Such a high-performance ceramics consists z. B. of the finest ceramic particles that are only a few millionths of a millimeter in size. The ceramic particles are used in a chemical substance by a sol-gel process. A resulting material may, for. B. applied by spraying and retains its ceramic properties and get new ones that include a new ability. This new ability is characterized z. B. by very good sliding properties.
In der Sperr-Betriebslage ist die Sperrklinke gegen Rotation in Bezug auf die Falle verriegelt. In dieser Stellung ist es notwendig, entweder eine Handbetätigung des Schlosses durchzuführen, was ein Einziehen der Falle in das Schloss bedeuten würde. Jedoch auch bei Türen mit Panikfunktion kann im Falle einer Panik eine solche entsperrbare Freigabevorrichtung von einer Warte freigeschaltet werden.In the locked mode, the pawl is locked against rotation with respect to the latch. In this position, it is necessary to perform either a manual operation of the castle, which is a retraction of the Trap in the lock would mean. However, even with doors with panic function, such a releasable release device can be unlocked from a control room in case of panic.
Um eine genaue Einstellung des Sperrhebels durchführen zu können, kann dieser beispielsweise an seinem einseitigen Drehpunkt exzentrisch gelagert werden. Durch eine Verdrehung des Exzenters werden somit der Eingriffspunkt und damit auch der Freigabepunkt der Sperrfläche verändert.In order to perform a precise adjustment of the locking lever, it can be mounted eccentrically, for example, at its one-sided pivot point. By a rotation of the eccentric thus the engagement point and thus the release point of the blocking surface are changed.
Des Weiteren befindet sich in der elektrisch entsperrbaren Freigabevorrichtung eine Rückmeldung für die Stellung des Ankers gegenüber der Spule, wobei eben zwei Zustände "Anker angezogen" bzw. "Anker nicht angezogen" angezeigt werden können. In gleicher Weise gibt es eine Rückmeldung für das Einfahren der Falle des Schlosses in die Freigabevorrichtung. Hierfür ist ein federbelasteter Hebel vorgesehen, der innerhalb der Sperrklinke eingebettet ist. Durch das Auftreffen der Falle auf den Hebel bewirkt dieser in Verbindung mit einem entsprechenden Schaltelement eine Rückmeldung, ob die Falle eingefahren ist oder nicht.Furthermore, there is a feedback in the electrically releasable release device for the position of the armature relative to the coil, wherein just two states "anchor attracted" and "anchor not tightened" can be displayed. In the same way there is a feedback for the retraction of the case of the lock in the release device. For this purpose, a spring-loaded lever is provided, which is embedded within the pawl. By the impact of the case on the lever this causes in conjunction with a corresponding switching element feedback, whether the case is retracted or not.

In den Figuren ist die erfindungsgemäße elektrisch entsperrbare Freigabevorrichtung für Türen nur insoweit dargestellt worden, als es für die Erläuterung der Erfindung von Bedeutung ist.In the figures, the invention electrically releasable release device for doors has been shown only insofar as it is important for the explanation of the invention.
In den Figuren ist ein Anker 1 und eine zugehörige Spule 2 für eine elektrisch entsperrbare Freigabevorrichtung 26 für eine Tür wiedergegeben.In the figures, an
Der Anker 1 ist erfindungsgemäß U-förmig ausgebildet und weist zwei freie Schenkel 4 und 5 auf. An den beiden Schenkeln 4 und 5 sind Führungsbahnen 8 angeordnet, mit denen der Anker 1 an bzw. unter der Spule 2 gleitend geführt werden kann. Um das Gleiten des Ankers 1 zu verbessern, ist eine Gleitbeschichtung 18 vorzugsweise an den Führungsbahnen 8 des U-förmigen Ankers 1 und an den Gegenlagern 12 der Spule 2 sowie auf einem Boden 54 eines Gehäuses 28 der Freigabevorrichtung 26 vorgesehen. Durch eine derartige Gleitführung, die z. B. aus einer Hochleistungskeramik bestehen kann, kann der Anker 1 in dem Gehäuse 28 der Freigabevorrichtung 26 gegen das Gegenlager 12 an der Spule 2 mit einem sehr geringen Reibungskoeffizienten bewegt werden. Durch die Herabsetzung der Reibungskräfte kann auch die Leistung der Spule 2 herabgesetzt werden, was eine Reduzierung des Stromverbrauches bedeutet und damit eine kleinere Baugröße einer erfindungsgemäßen Freigabevorrichtung 26 ermöglicht.The
An seinem freien Ende trägt der eine Schenkel 5 des U-förmigen Ankers 1 eine Gabel 19, die von einer Achse 7 durchgriffen wird, an der eine Sperrrolle 6 gelagert ist. In dem gleichen Schenkel 5 ist auch eine als Sackloch ausgebildete Federkammer 21 angeordnet, die sich achsparallel zum Schenkel 5 erstreckt und zur Aufnahme einer Feder 10 dient. Weiterhin ist an dem Schenkel 5 eine im Wesentlichen mittig angeordnete Rolle 25 gelagert. Statt der ortsfest gelagerten Rolle kann auch ein federbelasteter Keil verwendet werden.At its free end, the one
Der andere Schenkel 4 des U-förmigen Ankers 1 ist mit zwei jeweils als Sackloch ausgebildeten Federkammern 22, 23 versehen, die auf einer gemeinsamen Achse hintereinander liegend angeordnet und achsparallel zu dem Schenkel 4 ausgerichtet sind. Diese Federkammern 22, 23 dienen zur Aufnahme von zwei Federn 16, 17 (siehe
An dem Anker 1 ist ein Remanenzstift 9 gelagert, der im Wesentlichen mittig in einem die beiden Schenkel 4, 5 verbindenden Mittelteil 20 angeordnet ist und in Richtung der freien Enden der Schenkel 4, 5 in das Innere des U-förmigen Ankers 1 vorsteht (vgl.
In dem von den beiden Schenkeln 4, 5 umschlossenen Raum ist die Spule 2 gelagert. Die Spule 2 besteht aus einem Gehäuse 15, an dem zwei Führungsflächen als Gegenlager 12 zu den Führungsbahnen 8 ausgebildet sind. Hierdurch wird deutlich, dass der Anker 1 quasi als Schlitten ausgebildet ist und bei einer Bestromung der Spule 2 gegen die Spule 2 gezogen wird. Als Rückstellkräfte dienen die Federn 16, 17 und 10. Durch diese Konstruktion wird der Anker 1 an den beidseitigen Gegenlagern 12 zwangsgeführt, was gleichzeitig eine stabile Einbaulage definiert. In dem Gehäuse 15 ist ein Spulenkörper mit Wicklung 14 gelagert. Der Spulenkörper 14 ist mit einer mittigen Öffnung versehen, in welcher ein Spulenkern 13 sitzt. Der Spulenkörper 14 ist weiterhin auf der nach außen weisenden Seite mit Anschlüssen 3 für eine Stromversorgung versehen. An dem Gehäuse 15, welches als Joch ausgeführt ist, befindet sich auch gleichzeitig eine Spulenbefestigung 11, mit der das Gehäuse 15 an oder in dem Gehäuse 28 befestigt werden kann. Das Gehäuse 15 der Spule 2 ist ganz oder teilweise aus einem ferromagnetischen Material gefertigt; ebenso der Anker 1.In the space enclosed by the two
In der
Gegen die Rolle 6 liegt eine Sperrfläche 48 eines Sperrhebels 33 an. Der Sperrhebel 33 ist einseitig an seinem der Sperrfläche 48 gegenüberliegenden Ende über eine Drehachse 46 drehbar gelagert. Innerhalb des Sperrhebels 33 befindet sich eine Sackbohrung 38, in der eine Feder 37 eintaucht und sich anderenends gegen eine Wandung des Gehäuses 28 abstützt. Die Drehachse 46 kann, wie es in der

Durch das Verschwenken der Sperrklinke 35 geht der Vorsprung 36 an der Anlauffläche 45 des Sperrhebels 33 vorbei, was eine Drehung der Sperrklinke 35 ermöglicht. Durch das Drehen der Sperrklinke 35 ist es möglich, die Öffnung der angeschlossenen Tür ohne eine Betätigung des Drückers der Tür zu bewirken. Dieses ist insbesondere für Türen in Flucht- und Rettungswegen von großer Bedeutung.By pivoting the
