Definitions
- the invention relates to a lock according to the preamble of claim 1.
- the castle known from this is a castle with a trap.
- the trap is designed as automatically by magnetic force in the closed position of the wing voratden latch, which is associated with a closing plate on the frame.
- the latch engages in the locking position in a latch opening of a striking plate, wherein the case of a lock housing precedes.
- the case is provided with a first magnet and in the strike plate, a second magnet is mounted, so that the first and the second magnet in the closed position of the wing displaces the case in the strike plate.
- the latch in the lock is determined by the fact that the first magnet cooperates with the lock housing or a magnetic metal part mounted therein.
- an electric door opener In order to open a lock remotely, an electric door opener is usually provided. This has a pivotally mounted and pivotable about an electromagnet pawl, which is seated in a latch opening of a frame-side striker. When the solenoid is activated, the pawl is pivoted so that the trap can escape from the trap opening.
- a disadvantage of the known embodiments is that the moving parts may only consist of non-ferritic materials when using the first-mentioned lock, otherwise the case gets stuck on the pawl or the bolt.
- the mobility of the pawl or the bolt is no longer certain, especially after a certain time.
- the object of the invention is therefore to provide a lock, which also provides a reliable door opening function in addition to a secure closing function.
- the door opener consists of an electric field generating coil which urges the trap from the strike plate.
- the trap is urged contactlessly by means of the electrical signal from the strike plate.
- an extremely simple, cost-effective and at the same time effective design is made, which completely dispenses with frame-side moving functional parts.
- the voltage which is applied to the coil corresponds to that of a conventional door opener.
- the coil surrounds the magnet in the strike plate. This creates a magnetic field of the case opposite magnetic field and it is claimed only a small space.
- FIGS. 1 and 2 a door 1 with a lock 2 is shown. Via the lock 2, the wing 3 of the door 1 can be fixed to the frame 4. A pusher 5 and a lock cylinder 6 are provided to operate the lock 2.
- the cross-section of the wing 3 is rectangular and lies in surfaces parallel alignment position to the frame 4 at this.
- the fold 8 of the wing 3 and the fold 9 of the frame 4 are in this case parallel to each other.
- the surface-parallel alignment position of the wing 3 and frame 4 - in accordance with Fig. 2 - Is referred to as a closed position and is independent of the intervention of a bolt 2 provided on the bolt 10 in a strike plate 11 on the frame. 4
- FIGS. 3 and 4 can be seen by means of enlarged cutouts that the lock 2 is seated in a recess 12 of the wing 2.
- the lock 2 is closed by a lock plate 13, while extending perpendicular to the plane of the drawing walls 14 protrude from the castle floor.
- a latch 10 effective case 15 Through an opening in the lock plate 13 projects as a latch 10 effective case 15.
- another on the lock cylinder 6 operable latch on the lock 2 can be provided.
- the latch 15 is provided for the wing 3 in the closed position ( Fig. 2 ) each automatically set.
- the traps are usually spring loaded and always protrude - ie in the open position of the wing 3 - in front of the lock plate 13.
- a first magnet 16 is provided in the case 15.
- a second magnet 18 is provided in the strike plate 11, which is mounted along the fold 9 in a recess 17 of the frame 4.
- the magnet 16 and the magnet 18 are designed and assigned to one another in the closed position so that the latch 15 is displaced into a latch opening 19 of the striking plate 11.
- the magnet 16 is received by a case housing 20.
- the trap housing 20 is made of plastic, as this results in a cost-effective production and easy assembly (for example, by a snap-latch connection) with the magnet 16 on the one hand.
- the trap 15 is substantially cuboid, so that the longitudinal side surfaces are substantially perpendicular to the fold 8 and 9. Due to the obtuse angle of the locking surfaces of the case 15 a reliable locking is ensured.
- the pusher 5 is actuated, the case 15 is retracted in a conventional manner. This can also be done via lock cylinder 6, to which the lock 2 has a change control. When pressed pusher 5, the case 15 is completely withdrawn into the lock housing, as in the FIGS. 5 and 6 shown.
- the latch 15 is fixed in the non-surface-parallel position of the blade 3 in the lock housing or the lock 3 in that the first magnet 16 cooperates with the lock housing formed of a ferromagnetic material or a ferromagnetic component mounted therein or a magnetic component part.
- the lock housing is made of sheet metal. The setting of the trap 15 is necessary to ensure that the trap 15 is retracted when the wing 3 is to be closed again.
- the lock plate 13 is made of a non-ferromagnetic metal, preferably stainless steel, to avoid interference.
- the magnets 16, 18 interact again.
- the magnetic field of the first and second magnets 16, 18 in the closed position runs almost perpendicular to the lock face 13.
- the poles of the magnets 16, 18 are opposite each other in such a way that they attract each other.
- the Ausstellweite the case 15 5 is adjustable, so that too large or small spacing of the rabbets 8, 9 and thus the magnets 16, 18 can be counteracted.
- the magnet 18 is mounted in a receptacle 22 projecting on the rear side of the striking plate 11 and protrudes into a bore 23 of the frame 4.
- a bottom 24 of the closing plate 11 made of non-ferromagnetic material avoids an immediate meeting of the case 15 and the magnet 16 and the magnet 18, since the bottom 24 forms a separating gap.
- the magnet 16 is coated with plastic or covered by the case 20 so that it is not visible from the outside, to prevent tampering.
- the magnets 16, 18 are identical in terms of their dimensions.
- the magnet 18 is wrapped with a coil 25 which is connected via terminals to a door opening system, not shown here.
- a current which then flows through the coil 25.
- a magnetic field is built up, which is opposite to the magnet 15, so that acts on the latch 15, a restoring force, which forces the case 15 out of the latch opening 19, so that the case 15 in the FIGS. 5 and 6 position shown assumes.
- the voltage applied by the door opening system, which is applied to the coil 25, corresponds to that of a conventional door opener. If there is no voltage on the coil 25, the magnet 18 is effective as described above and moves the latch 15 in the latch opening 19 when the magnets 16, 18 facing each other.
- the strike plate is made of a non-ferromagnetic material. It also contributes to the fact that the lock forend as already mentioned above - consists of a non-ferromagnetic metal - preferably stainless steel.
- the above-described embodiment of the lock 2 has many advantages.
- the spring normally to be provided for displacing the latch 15 can be dispensed with. Because the trap 15 in the fixed non-surface-parallel position of the wing in the lock 2, the closed position can be achieved almost noiseless, since the case 15 does not coincide with the frame 4 or the closing bleach 11 during immersion of the wing 3.
- the trap 15 does not protrude, moreover, has the advantage that the trap does not protrude in front of the fold in the open position.
- the latter is advantageous, especially in the case of flush-fitting doors which do not cover the frame.
- rebated doors the wing 3 strikes the frame 4 and covers it with a rollover, which protrudes from the fold 8.
- the arrangement with the coil 25 also allows an arrangement of a door opener, which manages without moving parts.
- case 15 is adjustable relative to the fold 8. This takes place, for example via an adjusting device, as in the DE 10321354 A1 to which reference is made in this regard.

Abstract
Description
Die Erfindung betrifft ein Schloss nach dem Oberbegriff des Anspruchs 1.The invention relates to a lock according to the preamble of claim 1.
Ein solches Schloss ist bereits aus der noch nicht veröffentlichten
Um ein Schloss von Ferne öffnen zu können, wird üblicherweise ein elektrischer Türöffner vorgesehen. Dieser weist eine schwenkbar gelagerte und über einen Elektromagnet schwenkbare Sperrklinke auf, welche in einer Fallenöffnung eines rahmenseitigen Schließblechs einsitzt. Bei aktiviertem Elektromagnet wird die Sperrklinke so verschwenkt, dass die Falle aus der Fallenöffnung austreten kann.In order to open a lock remotely, an electric door opener is usually provided. This has a pivotally mounted and pivotable about an electromagnet pawl, which is seated in a latch opening of a frame-side striker. When the solenoid is activated, the pawl is pivoted so that the trap can escape from the trap opening.
Aus der
Nachteilig bei den bekannten Ausgestaltungen ist es, dass die bewegten Teile bei Einsatz des erstgenannten Schlosses nur aus nicht ferritischen Werkstoffen bestehen dürfen, da ansonsten die Falle an der Sperrklinke bzw. dem Bolzen hängenbleibt. Zudem ist die Beweglichkeit der Sperrklinke oder des Bolzens insbesondere nach einem gewissen Zeitablauf nicht mehr sicher gegeben.A disadvantage of the known embodiments is that the moving parts may only consist of non-ferritic materials when using the first-mentioned lock, otherwise the case gets stuck on the pawl or the bolt. In addition, the mobility of the pawl or the bolt is no longer certain, especially after a certain time.
Aufgabe der Erfindung ist es daher ein Schloss anzugeben, welches neben einer sicheren Schließfunktion auch eine zuverlässige Türöffnerfunktion bereitstellt.The object of the invention is therefore to provide a lock, which also provides a reliable door opening function in addition to a secure closing function.
Zur Lösung dieser Aufgabe ist vorgesehen, dass der Türöffner, aus einer ein elektrisches Feld erzeugenden Spule besteht, welches die Falle aus dem Schließblech drängt. Dadurch wird die Falle berührungslos mittels des elektrischen Signals aus dem Schließblech gedrängt. Dadurch ist eine äußerst einfache, kostengünstige und zugleich wirkungsvolle Ausgestaltung getroffen, die vollständig auf rahmenseitig bewegte Funktionsteile verzichtet.To solve this problem, it is provided that the door opener, consists of an electric field generating coil which urges the trap from the strike plate. As a result, the trap is urged contactlessly by means of the electrical signal from the strike plate. As a result, an extremely simple, cost-effective and at the same time effective design is made, which completely dispenses with frame-side moving functional parts.
Um die bestehenden Türöffnungsanlagen weiterverwenden zu können, ist vorgesehen, dass die Spannung, welche an der Spule angelegt wird, der eines üblichen Türöffners entspricht.In order to continue to use the existing door opening systems, it is provided that the voltage which is applied to the coil corresponds to that of a conventional door opener.
Besonders vorteilhaft ist es, wenn die Spule den Magnet in dem Schließblech umgibt. Dadurch entsteht ein dem Magnetfeld der Falle gegenüberstehendes Magnetfeld und es wird nur ein geringer Bauraum beansprucht.It is particularly advantageous if the coil surrounds the magnet in the strike plate. This creates a magnetic field of the case opposite magnetic field and it is claimed only a small space.

Durch eine Öffnung in dem Schlossstulp 13 ragt eine als Riegel 10 wirksame Falle 15. Neben der Falle 15 kann ein weiterer über den Schließzylinder 6 betätigbarer Riegel an dem Schloss 2 vorgesehen werden. Im Gegensatz zu dem gegebenenfalls vorgesehenen weiteren Riegel ist die Falle 15 dafür vorgesehen, den Flügel 3 in der Schließstellung (
Bei dem dargestellten Schloss 2 ist in der Falle 15 ein erster Magnet 16 vorgesehen. In dem Schließblech 11, welches entlang dem Falz 9 in einer Ausnehmung 17 des Rahmens 4 angebracht ist, ist ein zweiter Magnet 18 vorgesehen. Der Magnet 16 und der Magnet 18 sind so ausgelegt und einander in der Schließstellung so zugeordnet, dass die Falle 15 in eine Riegelöffnung 19 des Schließblechs 11 verlagert wird.In the illustrated
Dabei wird der Magnet 16 von einem Fallengehäuse 20 aufgenommen. Das Fallengehäuse 20 besteht aus Kunststoff, da sich dadurch zum einen eine kostengünstige Herstellung und einfache Montage (z.B. durch eine Rast-Schnapp-Verbindung) mit dem Magneten 16 ergibt. Zum anderen ist dadurch, dass der Magnet 16 in dem Fallengehäuse 20 aus nichtmagnetisierbaren Material aufgenommen ist, eine ggf. auftretende Wechselwirkungen mit dem Schließblech 11 ausgeschlossen, da der Magnet 16 nicht direkt mit ferromagnetischen Komponenten in Verbindung tritt, die eine Beeinflussung des Magnetfeldes mit sich bringen würden.In this case, the
Die Falle 15 ist im Wesentlichen quaderförmig, so dass die Längsseitenflächen im Wesentlichen senkrecht zu dem Falz 8 und 9 verlaufen. Durch den stumpfen Winkel der Riegelflächen der Falle 15 ist eine zuverlässige Verriegelung gewährleistet.The
Wird ausgehend von der Schließlage nach
Wird der Flügel 3 nun verschwenkt, dann beeinflussen sich die Magnete 16, 17 nicht mehr gegenseitig. Dabei wird die Falle 15 in der nichtflächenparallelen Lage des Flügels 3 in dem Schlossgehäuse bzw. dem Schloss 3 dadurch festgelegt, dass der erste Magnet 16 mit dem aus einem ferromagnetischen Material gebildeten Schlossgehäuse oder einem darin gelagerten ferromagnetischen Bauteil oder einem magnetischen Bauteilteil zusammenwirkt. Die einfachste Ausgestaltung sieht dabei vor, dass das Schlossgehäuse aus Blech hergestellt wird. Das Festlegen der Falle 15 ist notwendig, um sicherzustellen, dass die Falle 15 zurückgezogen ist, wenn der Flügel 3 erneut geschlossen werden soll. Dem entgegen besteht der Schlossstulp 13 aus einem nicht-ferromagnetischen Metall vorzugsweise Edelstahl, um Beeinflussungen zu vermeiden.If the
Gelangt der Flügel 3 erneut in die Schließstellung, entsprechend
Ausweislich der
In dem Ausführungsbeispiel nach
Vorzugsweise ist - um Störungen zu vermeiden - auch vorgesehen, dass das Schließblech aus einem nicht-ferromagnetischen Werkstoff hergestellt ist. Dazu trägt auch bei, dass der Schlossstulp wie vorstehend bereits erwähnt - aus einem nicht-ferromagnetischen Metall - vorzugsweise Edelstahl - besteht.Preferably - to avoid interference - also provided that the strike plate is made of a non-ferromagnetic material. It also contributes to the fact that the lock forend as already mentioned above - consists of a non-ferromagnetic metal - preferably stainless steel.
Die vorstehend beschriebene Ausgestaltung des Schlosses 2 hat viele Vorteile. Durch den in dem Schließblech 11 angebrachten zweiten Magneten 18 und dadurch, dass der erste und der zweite Magnet 16, 18 so zueinander angeordnet sind, dass in Schließstellung des Flügels die Falle in das Schließblech verlagert wird, kann eine selbsttätige Verriegelung entsprechend einer federbelasteten Falle erreicht werden. In dem Schloss 2 kann die üblicherweise vorzusehende Feder zur Verlagerung der Falle 15 jedoch entfallen. Dadurch, dass die Falle 15 in der nichtflächenparallelen Lage des Flügels in dem Schloss 2 festgelegt ist, kann die Schließstellung fast geräuschlos erreicht werden, da die Falle 15 nicht mit dem Rahmen 4 oder dem Schließbleich 11 beim Eintauchen des Flügels 3 zusammentrifft. Dass die Falle 15 nicht vorsteht, hat zudem den Vorteil, dass die Falle in der Öffnungsstellung nicht vor dem Falz vorragt. Letzteres ist, insbesondere bei stumpf einschlagenden Türen, die den Rahmen nicht überdecken, von Vorteil. Bei überfalzten Türen schlägt der Flügel 3 an dem Rahmen 4 an und überdeckt diesen mit einem Überschlag, der von dem Falz 8 absteht. Dadurch sind vorstehende Fallen für solche Türen kein Problem. Die Anordnung mit der Spule 25 erlaubt zudem eine Anordnung eines Türöffners, welcher ohne bewegliche Teile auskommt.The above-described embodiment of the
Abschließend soll noch erwähnt werden, dass die Falle 15 relativ zum Falz 8 verstellbar ist. Dies erfolgt, z.B. über eine Verstelleinrichtung, wie in der
