Definitions
- the present invention relates to a mortise lock having a first nut for receiving a pusher and having a second nut for receiving a locking lever and / or a key, wherein the first nut is kinematically connected to a latch and wherein the second nut in a release position, in which the first nut is rotatable, and in a blocking position, in which the first nut and / or the trap is blocked, can be brought.
- sanitary rooms toilet, bath
- locks in use which have a trap and a bolt.
- the lock has a nut for receiving a pusher, which is usually provided on both sides of a pusher.
- a knob is possible.
- On the inside is in addition to the trigger a locking lever, which cooperates with the bolt. By a quarter turn of the locking lever, the bolt is extended or withdrawn.
- a square can be provided in order to be able to open the lock from the outside with a suitable tool, should this be e.g. be necessary because of an accident in the sanitary room.
- a mortise lock of the aforementioned type according to the invention that the axis of rotation of the second nut is arranged at a standard distance of 21.5 mm below the axis of rotation of the first nut.
- Mortise locks have according to standard various openings that are used for mounting of door shields or rosettes. There are on both sides of the nut openings for fixing rosettes, these openings have a distance of 38 mm from each other (distance from the axis of rotation of the nut so 19 mm). Furthermore, there is an opening at a distance of 21.5 mm to the axis of rotation of the nut to attach the shield below the nut. This opening is intended for the attachment of a short shield, but is sometimes used as the third attachment point (approximately in the middle) of long shields. For the upper and lower attachment of long shields no opening in the mortise lock is necessary because these attachment points are located above and below the lock box.
- the axis of rotation of the second nut is now located exactly at the location of the opening for the short shield attachment, resulting in two advantages.
- this opening is still within the diameter of ordinary rosettes, i. the locking lever can be fixed on the single rosette, and secondly a conventional lock case can be used.
- the lock according to the invention only two new parts are necessary: the nut for the handle and the nut for the locking lever. All other parts are standard parts of standard locks.
- the present invention can therefore also be applied to special locks, such as e.g. with magnetic latch locks.
- the second nut made of plastic.
- the first nut from plastic, as is already known, in order to save further costs.
- the first nut has a part-cylindrical recess whose center axis - in the rest position of the first nut - coincides with the axis of rotation of the second nut, and that the second nut in the Blocking position engages with a corresponding part-cylindrical projection in this part-cylindrical recess.
- the interaction of part-cylindrical recess and part-cylindrical projection results in rich, relatively large bearing surfaces, so that the pressure remains relatively low in an attempt to operate a locked pusher. Nevertheless, the projection of the second nut can be brought without resistance into the locking position, because the axis of the cylindrical recess or the cylindrical projection coincides with the axis of rotation of the second nut.
- a projection adjoins a corresponding stop surface of the first nut in the blocking position of the second nut. This not only results in a stop when operating the locking lever (when moving into the locking position), this also causes that in an attempt to operate a locked pusher, the force is absorbed not only by the part-cylindrical recess and the part-cylindrical projection, but also from the projection and the stop surface. The force is thus distributed over an even larger area, so that the pressure is reduced again, which is advantageous in particular when using plastic.
- the second nut is made of plastic, there is a risk that - when the pusher is operated with very high force in the blocked state - the projections of the second nut, with which the second nut is mounted in the lock case or in the lid, sheared off , To avoid this, it is provided according to a further embodiment of the invention that articulated on the second nut a pawl is, which is inserted by rotation of the second nut between a stop and a projection of the first nut.
- the stopper is relatively small compared to the second nut, and therefore can be made of metal much too much without the cost of manufacturing and riveted in the lock case. The force applied to the pusher is thus absorbed by this stop, and the second nut is relieved, so that it can be inexpensively made of plastic.
- a guide surface is provided to guide the pawl upon rotation of the second nut between the stop and the projection of the first nut.
- Another problem is that it is possible to lock the lock with the door open and then slam the door shut. While it is customary to provide an emergency opening on the outside of the door (with a special wrench or with a screwdriver), it is often the case that the corresponding tool is not available. It is therefore provided according to a further embodiment of the invention that by twisting the second nut a latch locking member for blocking the case is displaced. In this way, the case can not be pushed back when the lock is locked, so that the door can not be slammed.
- the blocking of the first nut could be dispensed with, as it can not be twisted anyway in the case of a locked trap.
- the lever that is connected to the first nut to pull back the trap is very heavily loaded when trying to operate the pusher with locked lock, so that there is a risk that this lever breaks, especially if the first nut and this lever made of plastic. It is therefore often useful to provide both blocks.
- a particularly simple construction which can still absorb very high forces, can be realized in that the locking part between the shaft of the case and the lock case is pushed. In this case, the lock case would have to be deformed to push the trap against the blockage back.
- the second nut has a substantially square recess for receiving a square pin, wherein in each case a groove is provided on at least one side surface, preferably on all four side surfaces, starting from a flat side of the second nut.
- a locking lever which is common on the inside
- This key is essentially a pin with either a projection on the end (which engages in one groove or in one of the grooves) or with two diametrically opposed projections which engage in opposite grooves. In the latter case, the forces are symmetrically introduced into the second nut, which makes it easier to twist.
- such a key with two diametrically opposed protrusions looks less like a conventional truncated key.
- the lock is to be locked and unlocked from both sides with a key, then starting from the other flat side of the second nut on at least one side face, preferably on all four side faces, one groove each is provided, which is in front of the center plane of the second nut ends.

- Fig. 12 a fourth embodiment of a mortise lock according to the invention with removed lock case lid in the open position, and Fig. 12 the same in locked position.
- the Fig. 1 to 5 show an inventive mortise lock with shortened lock case.
- the lock case 11 has a lid 12 (s. Fig. 1 ) on; Lock case 11 and lid 12 have an opening for a first nut 13 according to standards.
- On both sides of the first nut 13 are openings 14, 15 (s. Fig. 2 to 4 ), through each of which a pin 16 (s. Fig. 1 ) a rosette 17 goes, so that the rosette 17 with the opposite rosette (not shown) can be firmly connected and thus both rosettes can be fixed.
- These two openings are according to the standard a distance of 38 mm from each other.
- an opening 19 is also provided, which is 21.5 mm below the axis of rotation of the nut 13.
- This opening 19 is according to the standard for attachment of a Short shield provided, it is according to the present invention, however, for supporting a second nut 20 (s. Fig. 2 to 5 ) used.
- a case 21 is provided, which is formed the same as in the currently customary standard locks; it protrudes through a corresponding opening in a cuff 22 to the outside and has a shaft 23 with a projection 23 'at its free end.
- the first nut 13 has a projection 13 'which cooperates with the projection 23', whereby the latch 21 can be retracted by rotation of the first nut 13 into the interior of the lock (see Fig. 4 ).
- the lock case 11 and in the lid 12 are in the lid 12 (s. Fig. 1 )
- Window 24 s. Fig. 2 to 5
- 25 s. Fig.
- the case 21 is further in the usual way by a spring 26 (s. Fig. 2 to 5 ) biased outwards.
- the first nut 13 as previously biased by a spring 27.
- two connected by a bracket 18 sleeves on the openings 14, 15 are also provided in a known manner.
- the bracket 18 facilitates installation, it must be inserted only a part.
- the bracket 18 together with sleeves can be inexpensively made of plastic.
- the sleeves serve on the one hand to prevent the penetration of chips of the door into the lock, and they also serve to better guide the pins 16 on the other hand (s. Fig. 1 ) to the rosette attachment.
- the formation of the first nut 13 and the fact that at the opening 19, the second nut 20 (s. Fig. 2 to 5 ) is provided.
- the first nut 13 has a part-cylindrical recess 28 (see Fig. 3 and 4 ) whose central axis - at rest of the first nut (see Fig. 3 ) - coincides with the axis of rotation of the second nut 20.
- the second nut 20 has a corresponding part-cylindrical projection 29, which in the blocking position (see Fig. 2 ) in the part-cylindrical Recess 28 engages.
- At the partially cylindrical projection 29 of the second nut 20 closes in the direction of rotation of the blocking position in the release position - ie right, as in Fig. 2 shown - a projection 30 which in the blocking position of the second nut 20 (s. Fig.
- This lock is therefore largely produced from standard parts, in addition to produce only the two nuts 13 and 20, and can be inexpensively made of plastic.
- the nut 13 could also be used with standard locks, so that after a corresponding production change compared to these standard locks, only the second nut 20 is additionally required. If you want to make a standard lock, you leave the second nut 20, if you want to make a lock with blocking possibility, you put the second nut 20 a.
- the cost of the lock according to the invention with blocking possibility are hardly higher than the cost of a standard lock. It is only a plastic part in addition to use.
- the second nut 20 has in the middle a substantially square recess 32 for receiving a square pin.
- a substantially square recess 32 for receiving a square pin.
- one groove 34a, 34b, 34c and 34d is provided in each case.
- These grooves 34a, 34b, 34c and 34d extend from the flat side of the second nut 20 facing the viewer and terminate in front of the midplane of the second nut 20. From the viewer facing away flat side of the second nut 20 also go out four grooves, but in Fig. 6 only two grooves 35a, 35b are visible. These grooves also end in front of the median plane of the second nut 20, so that the normal square contour remains in the area of the median plane.
- the second nut can now be operated in two ways: One can provide a locking lever, which is provided with a square, which engages in the square recess 32. This will normally be done on the inside of the door.
- the locking lever can be mounted in a correspondingly designed rosette. But you can also provide a rosette with an opening 36 (see Fig. 1 ), in which a key 37 can be inserted.
- This key 37 (see Fig. 6 ) can with two diametrically opposed projections 38a, 38b in two opposing grooves 34b, 34d; or 34a, 34c. Since the grooves 34b, 34d; or 34a, 34c in front of the median plane of the second nut 20, this results in a depth stop for the key 37.
- the rosette 17 (see Fig. 1 ) Has for this purpose an opening 36. So that the key is always inserted correctly, the opening 36 in the rosette 17 consists of a circular hole whose diameter corresponds approximately to the shaft of the key 37, wherein the circular hole top, bottom left and right four recesses go out to make room for the projections 38 a, 38 b (see Fig. 6 ) of the key 37.
- the key 37 is guided in the circular hole, and the projections 38a, 38b are always positioned to fit in the grooves 34b, 34d; or 34a, 34c intervene.
- the present invention can also be implemented in conventional (long) lock cases 11. Since a bolt is not necessary (it can be the pusher blocked), no bolt is inserted. Also the parts belonging to the bolt (tumblers, springs etc) are missing. Another difference is that the first nut 13 is not biased by its own spring, the first nut 13 is pressed only by the latch 21 and its spring 26 in the rest position. This also saves costs. Due to the lack of spring for the first nut 13, the first nut 13 can be modified, ie the projection on which the spring 27 (see Fig. 2 to 5 ) is applied, can be omitted, so it can be saved material.
- the second nut 20 in the embodiment according to the Fig. 7-9 loaded down to the left, and this force must be absorbed by the storage. Since the storage in the relatively small, provided in the thin sheet according to the standard Opening 19 can absorb too large forces, there is a risk that the projections provided for the storage of the second nut 20 are sheared off. This problem is caused by the execution according to the Fig. 10 and 11 eliminated.
- a guide surface 44 is provided, which is expediently mounted on the bracket 18, which carries the two sleeves for the openings 14, 15. There is thus no additional part to be inserted.
- FIG. 7-9 Another problem with the execution according to the Fig. 7-9 is that it is possible to block the lock with the door open and then slam the door so that it can only be opened with the key 37 or in the version with a continuous square with a square wrench. Because in the execution according to the Fig. 7-9 the latch 21 can be pushed in even when the lock is locked.
- the locking member 51 has a projection 52, which is in unlocked lock (s. Fig. 10 ) is located above the shaft 23.
- the second nut 20 has a web 53 which engages in a groove 54 of the locking part 51. If now the second nut 20 in the blocking position, that is rotated in a clockwise direction, the locking member 51 is moved downward until the sleeve for the opening 15 prevents further movement. In this position, the projection 52 is located between the free end of the shaft 23 and the edge of the lock case 11, so that the latch 21 is blocked. In this position, also, the web 53 can slide out of the groove 54, and the second Nut 20 may complete the remainder of the movement necessary for the blocking of the first nut 13 (ie the remainder of the quarter turn) without further displacing the locking member 51.
- a magnetic latch lock is shown in the Fig. 12 and 13 .
- the blocking of the first nut 13 and the latch 21 works the same as in the lock according to the Fig. 10 and 11 ,
- the shaft 23 and the projection 52 are slightly different in order to insert the latch 21 (magnetic latch locks the case 21 is inserted with the door open and is only extended when closing the door by magnetic forces) a displacement of the locking member 51 and thus a rotation of the second nut 20 to prevent.

Abstract
Das Einsteckschloss weist eine erste Nuss (13) zur Aufnahme eines Drückers (17') und eine zweite Nuss (20) zur Aufnahme eines Verriegelungshebels auf. Die erste Nuss (13) ist mit einer Falle (21) kinematisch verbunden, und mit der zweiten Nuss (20) kann die erste Nuss (13) blockiert werden. Erfindungsgemäß ist die Drehachse der zweiten Nuss (20) im Normabstand von 21,5 mm unterhalb der Drehachse der ersten Nuss (13) angeordnet, sodass Normteile für den Schlosskasten verwendbar sind. Vorzugsweise ist die zweite Nuss (20) aus Kunststoff hergestellt. Um den Druck bei Betätigung eines blockierten Drückers auf die zweite Nuss (20) gering zu halten, kann die erste Nuss (13) eine teilzylindrische Ausnehmung (28) haben, in die die zweite Nuss (20) mit einem entsprechenden teilzylindrischen Vorsprung (29) zur Blockierung eingreift. Damit die zweite Nuss sowohl mit einem Verriegelungshebel als auch mit einem Schlüssel (37) betätigt werden kann, weist die zweite Nuss (20) eine im Wesentlichen quadratische Ausnehmung (32) zur Aufnahme eines Vierkantstiftes auf, wobei an zumindest einer Seitenfläche (33) eine Nut (34a-d; 35a-b) vorgesehen ist.The mortise lock has a first nut (13) for receiving a pusher (17 ') and a second nut (20) for receiving a locking lever. The first nut (13) is kinematically connected to a latch (21), and the second nut (20) can block the first nut (13). According to the invention, the axis of rotation of the second nut (20) is arranged at a standard distance of 21.5 mm below the axis of rotation of the first nut (13), so that standard parts can be used for the lock case. Preferably, the second nut (20) is made of plastic. In order to minimize the pressure on actuation of a locked pusher on the second nut (20), the first nut (13) may have a part-cylindrical recess (28) into which the second nut (20) with a corresponding part-cylindrical projection (29) engages for blocking. In order that the second nut can be actuated both with a locking lever and with a key (37), the second nut (20) has a substantially square recess (32) for receiving a square pin, wherein at least one side surface (33) Groove (34a-d; 35a-b) is provided.
Description
Die vorliegende Erfindung betrifft ein Einsteckschloss mit einer ersten Nuss zur Aufnahme eines Drückers und mit einer zweiten Nuss zur Aufnahme eines Verriegelungshebels und/oder eines Schlüssels, wobei die erste Nuss mit einer Falle kinematisch verbunden ist und wobei die zweite Nuss in eine Freigabestellung, in welcher die erste Nuss drehbar ist, und in eine Blockierstellung, in welcher die erste Nuss und/oder die Falle blockiert ist, bringbar ist.The present invention relates to a mortise lock having a first nut for receiving a pusher and having a second nut for receiving a locking lever and / or a key, wherein the first nut is kinematically connected to a latch and wherein the second nut in a release position, in which the first nut is rotatable, and in a blocking position, in which the first nut and / or the trap is blocked, can be brought.
Für Sanitärräume (WC, Bad) sind derzeit zumeist Schlösser im Einsatz, die eine Falle und einen Riegel aufweisen. Das Schloss hat eine Nuss zur Aufnahme eines Drückers, wobei idR auf beiden Seiten ein Drücker vorgesehen ist. Alternativ ist natürlich auch ein Drehknauf möglich. Auf der Innenseite befindet sich zusätzlich zum Drücker ein Verriegelungshebel, der mit dem Riegel zusammenwirkt. Durch eine Vierteldrehung des Verriegelungshebels wird der Riegel ausgefahren bzw. zurückgezogen. Auf der Außenseite kann ein Vierkant vorgesehen sein, um mit einem entsprechenden Werkzeug das Schloss auch von außen öffnen zu können, sollte dies z.B. wegen eines Unfalls im Sanitärraum notwendig sein.For sanitary rooms (toilet, bath) are currently mostly locks in use, which have a trap and a bolt. The lock has a nut for receiving a pusher, which is usually provided on both sides of a pusher. Alternatively, of course, a knob is possible. On the inside is in addition to the trigger a locking lever, which cooperates with the bolt. By a quarter turn of the locking lever, the bolt is extended or withdrawn. On the outside, a square can be provided in order to be able to open the lock from the outside with a suitable tool, should this be e.g. be necessary because of an accident in the sanitary room.
Weiters sind für Sanitärräume auch Lösungen ohne Riegel bekannt, bei denen durch Betätigung eines Verriegelungshebels die Falle blockiert wird, siehe z.B. die
Nachteilig bei diesen Lösungen ist, dass zumindest an der Innenseite der Tür entweder ein Langschild montiert werden muss oder aber zwei Rosetten montiert werden müssen (zur Aufnahme des Drückers und des Verriegelungshebels). Die Tendenz geht aber bei Innentüren dahin, nur eine Rosette (für den Drücker) vorzusehen, weil eine Versperrmöglichkeit - abgesehen von Sanitärräumen - in der Praxis kaum genützt wird. Verzichtet man auf die Versperrmöglichkeit, ist eine zweite Rosette für das Schlüsselloch entbehrlich, was allgemein als optisch vorteilhaft angesehen wird. Bei diesen Schlössern kann auch der Schlosskasten kürzer ausgeführt werden, und auch das Schließblech kann kürzer sein.A disadvantage of these solutions is that at least on the inside of the door either a long plate must be mounted or two rosettes must be mounted (to accommodate the handle and the locking lever). But the tendency is for interior doors to provide only a rosette (for the pusher), because a Versperrmöglichkeit - apart from sanitary facilities - is hardly used in practice. If you omit the obstruction possibility, a second rosette for the keyhole is dispensable, which is generally regarded as visually advantageous. In these locks, the lock case can be made shorter, and also the strike plate can be shorter.
Die oben genannten Lösungen für Sanitärräume mit zwei Rosetten oder einem Langschild passen dann aber optisch nicht mehr zu den übrigen Türen mit nur einer Rosette.However, the above-mentioned solutions for sanitary rooms with two rosettes or a long shield then optically no longer match the other doors with only one rosette.
Um dem abzuhelfen sind auch schon Rosetten bekannt geworden, die den Verriegelungsmechanismus bereits beinhalten. Solch eine Lösung ist in der
Um dieses starke Auftragen zu vermeiden ist auch schon bekannt geworden, die Tür entsprechend auszufräsen, sodass der Mechanismus im Inneren der Tür (zwischen Einsteckschloss und Türaußenfläche) zu liegen kommt. Dies kommt aber einer Beschädigung (Entwertung) der Türe gleich, denn an dieser Türe können keine anderen Rosetten, insbesondere keine Rosetten mit kleinerem Durchmesser, montiert werden, was bei einer Neugestaltung nachteilig ist.In order to avoid this heavy application has already become known, auszufräsen the door accordingly, so that the mechanism inside the door (between mortise lock and door outer surface) comes to rest. But this comes a damage (devaluation) of the door the same, because on this door no other rosettes, especially no rosettes with a smaller diameter, can be mounted, which is disadvantageous in a redesign.
Es ist Aufgabe der vorliegenden Erfindung, ein Einsteckschloss zu schaffen, das möglichst kostengünstig herstellbar ist, das eine Verriegelungsmöglichkeit aufweist und das mit nur einer Rosette, die nicht oder nur unwesentlich stärker aufträgt als herkömmliche Rosetten, auf jeder Seite der Türe auskommt, wobei keine Beschädigung der Türe (wie eine zusätzliche Ausfräsung) notwendig sein soll.It is an object of the present invention to provide a mortise lock, which can be produced as inexpensively as possible, which has a locking option and which with only one rosette, which does not or only marginally stronger than conventional rosettes on each side of the door gets along, with no damage to the door (such as an additional cutout) should be necessary.
Diese Aufgabe wird durch ein Einsteckschloss der eingangs genannten Art erfindungsgemäß dadurch gelöst, dass die Drehachse der zweiten Nuss im Normabstand von 21,5 mm unterhalb der Drehachse der ersten Nuss angeordnet ist.This object is achieved by a mortise lock of the aforementioned type according to the invention that the axis of rotation of the second nut is arranged at a standard distance of 21.5 mm below the axis of rotation of the first nut.
Einsteckschlösser haben laut Norm verschiedene Öffnungen, die zur Montage von Türschilden bzw. Rosetten dienen. So gibt es zu beiden Seiten der Nuss Öffnungen zur Befestigung von Rosetten, wobei diese Öffnungen einen Abstand zueinander von 38 mm aufweisen (Abstand von der Drehachse der Nuss also 19 mm). Weiters gibt es zur Befestigung des Schildes unterhalb der Nuss eine Öffnung im Abstand von 21,5 mm zur Drehachse der Nuss. Diese Öffnung ist zur Befestigung eines Kurzschildes gedacht, wird aber manchmal auch als dritter Befestigungspunkt (etwa in der Mitte) von Langschilden genutzt. Für die obere und untere Befestigung von Langschilden ist keine Öffnung im Einsteckschloss notwendig, denn diese Befestigungspunkte befinden sich oberhalb und unterhalb des Schlosskastens.Mortise locks have according to standard various openings that are used for mounting of door shields or rosettes. There are on both sides of the nut openings for fixing rosettes, these openings have a distance of 38 mm from each other (distance from the axis of rotation of the nut so 19 mm). Furthermore, there is an opening at a distance of 21.5 mm to the axis of rotation of the nut to attach the shield below the nut. This opening is intended for the attachment of a short shield, but is sometimes used as the third attachment point (approximately in the middle) of long shields. For the upper and lower attachment of long shields no opening in the mortise lock is necessary because these attachment points are located above and below the lock box.
Gemäß der Erfindung ist nun die Drehachse der zweiten Nuss genau an der Stelle der Öffnung für die Kurzschildbefestigung angeordnet, wodurch sich zwei Vorteile ergeben. Erstens befindet sich diese Öffnung noch innerhalb des Durchmessers üblicher Rosetten, d.h. der Verriegelungshebel kann auf der einzigen Rosette fixiert werden, und zweitens kann ein herkömmlicher Schlosskasten verwendet werden. Für das erfindungsgemäße Schloss sind nur zwei neue Teile notwendig: die Nuss für den Drücker und die Nuss für den Verriegelungshebel. Alle anderen Teile sind Standardteile normgerechter Schlösser. Die vorliegende Erfindung lässt sich daher auch bei Spezialschlössern anwenden, wie z.B. bei Magnetfallenschlössern.According to the invention, the axis of rotation of the second nut is now located exactly at the location of the opening for the short shield attachment, resulting in two advantages. First, this opening is still within the diameter of ordinary rosettes, i. the locking lever can be fixed on the single rosette, and secondly a conventional lock case can be used. For the lock according to the invention only two new parts are necessary: the nut for the handle and the nut for the locking lever. All other parts are standard parts of standard locks. The present invention can therefore also be applied to special locks, such as e.g. with magnetic latch locks.
Um die Kosten möglichst gering zu halten ist es zweckmäßig, die zweite Nuss aus Kunststoff herzustellen. Selbstverständlich ist es auch möglich, die erste Nuss aus Kunststoff herzustellen, wie dies bereits bekannt ist, um weitere Kosten zu sparen.In order to keep the costs as low as possible, it is expedient to produce the second nut made of plastic. Of course, it is also possible to produce the first nut from plastic, as is already known, in order to save further costs.
Um nun trotz der geringeren Festigkeit von Kunststoff eine zuverlässige Verriegelung zu erreichen ist es zweckmäßig, dass die erste Nuss eine teilzylindrische Ausnehmung hat, deren Mittelachse - in Ruhestellung der ersten Nuss - mit der Drehachse der zweiten Nuss zusammenfällt, und dass die zweite Nuss in der Blockierstellung mit einem entsprechenden teilzylindrischen Vorsprung in diese teilzylindrische Ausnehmung eingreift. Durch das Zusammenwirken von teilzylindrischer Ausnehmung und teilzylindrischem Vorsprung ergeben sich satte, relativ große Auflageflächen, sodass der Druck bei einem Versuch, einen verriegelten Drücker zu betätigen, relativ gering bleibt. Dennoch lässt sich der Vorsprung der zweiten Nuss ohne Widerstand in die Verriegelungsstellung bringen, weil die Achse der zylindrischen Ausnehmung bzw. des zylindrischen Vorsprungs mit der Drehachse der zweiten Nuss zusammenfällt.In order to achieve a reliable locking despite the lower strength of plastic, it is expedient that the first nut has a part-cylindrical recess whose center axis - in the rest position of the first nut - coincides with the axis of rotation of the second nut, and that the second nut in the Blocking position engages with a corresponding part-cylindrical projection in this part-cylindrical recess. The interaction of part-cylindrical recess and part-cylindrical projection results in rich, relatively large bearing surfaces, so that the pressure remains relatively low in an attempt to operate a locked pusher. Nevertheless, the projection of the second nut can be brought without resistance into the locking position, because the axis of the cylindrical recess or the cylindrical projection coincides with the axis of rotation of the second nut.
Bei dieser Ausführungsform ist es weiters zweckmäßig, wenn an den teilzylindrischen Vorsprung der zweiten Nuss in Drehrichtung von der Blockierstellung in die Freigabestellung ein Vorsprung anschließt, der in der Blockierstellung der zweiten Nuss an einer entsprechenden Anschlagfläche der ersten Nuss anliegt. Dadurch ergibt sich nicht nur ein Anschlag beim Betätigen des Verriegelungshebels (bei der Bewegung in die Verriegelungsstellung), dies bewirkt auch, dass bei einem Versuch, einen verriegelten Drücker zu betätigen, die Kraft nicht nur von der teilzylindrischen Ausnehmung und dem teilzylindrischen Vorsprung aufgenommen wird, sondern zusätzlich auch vom Vorsprung und der Anschlagfläche. Die Kraft verteilt sich also auf einen noch größeren Bereich, sodass der Druck nochmals reduziert wird, was insbesondere bei Verwendung von Kunststoff vorteilhaft ist.In this embodiment, it is further expedient if, adjoining the partially cylindrical projection of the second nut in the direction of rotation from the blocking position into the release position, a projection adjoins a corresponding stop surface of the first nut in the blocking position of the second nut. This not only results in a stop when operating the locking lever (when moving into the locking position), this also causes that in an attempt to operate a locked pusher, the force is absorbed not only by the part-cylindrical recess and the part-cylindrical projection, but also from the projection and the stop surface. The force is thus distributed over an even larger area, so that the pressure is reduced again, which is advantageous in particular when using plastic.
Wenn die zweite Nuss aus Kunststoff hergestellt ist, besteht die Gefahr, dass - wenn der Drücker mit sehr hoher Kraft im blockierten Zustand betätigt wird - die Vorsprünge der zweiten Nuss, mit denen die zweite Nuss im Schlosskasten bzw. im Deckel gelagert ist, abgeschert werden. Um dies zu vermeiden ist nach einer weiteren Ausgestaltung der Erfindung vorgesehen, dass an der zweiten Nuss eine Klinke angelenkt ist, die durch Drehung der zweiten Nuss zwischen einen Anschlag und einen Vorsprung der ersten Nuss einschiebbar ist. Der Anschlag istverglichen mit der zweiten Nuss - relativ klein und kann daher ohne die Herstellungskosten zu stark zu erhöhen aus Metall hergestellt und im Schlosskasten eingenietet werden. Die auf den Drücker aufgebrachte Kraft wird somit von diesem Anschlag aufgenommen, und die zweite Nuss ist entlastet, sodass sie kostengünstig aus Kunststoff hergestellt werden kann.If the second nut is made of plastic, there is a risk that - when the pusher is operated with very high force in the blocked state - the projections of the second nut, with which the second nut is mounted in the lock case or in the lid, sheared off , To avoid this, it is provided according to a further embodiment of the invention that articulated on the second nut a pawl is, which is inserted by rotation of the second nut between a stop and a projection of the first nut. The stopper is relatively small compared to the second nut, and therefore can be made of metal much too much without the cost of manufacturing and riveted in the lock case. The force applied to the pusher is thus absorbed by this stop, and the second nut is relieved, so that it can be inexpensively made of plastic.
In diesem Fall ist es zweckmäßig, wenn eine Führungsfläche vorgesehen ist, um die Klinke bei Drehung der zweiten Nuss zwischen den Anschlag und den Vorsprung der ersten Nuss zu führen.In this case, it is expedient if a guide surface is provided to guide the pawl upon rotation of the second nut between the stop and the projection of the first nut.
Ein weiteres Problem besteht darin, dass es möglich ist, das Schloss bei offener Tür zu blockieren und danach die Türe zuzuschlagen. Es ist zwar üblich, an der Außenseite der Tür eine Möglichkeit für eine Notöffnung vorzusehen (mit einem speziellen Schlüssel oder mit einem Schraubendreher), aber oft steht entsprechendes Werkzeug nicht zur Verfügung. Es ist daher nach einer weiteren Ausgestaltung der Erfindung vorgesehen, dass durch Verdrehen der zweiten Nuss ein Fallenverriegelungsteil zur Blockierung der Falle verschiebbar ist. Auf diese Weise kann die Falle bei blockiertem Schloss nicht zurück gedrückt werden, so dass die Türe auch nicht zugeschlagen werden kann.Another problem is that it is possible to lock the lock with the door open and then slam the door shut. While it is customary to provide an emergency opening on the outside of the door (with a special wrench or with a screwdriver), it is often the case that the corresponding tool is not available. It is therefore provided according to a further embodiment of the invention that by twisting the second nut a latch locking member for blocking the case is displaced. In this way, the case can not be pushed back when the lock is locked, so that the door can not be slammed.
In diesem Fall könnte die Blockierung der ersten Nuss entfallen, da diese bei blockierter Falle ohnehin nicht verdreht werden kann. Allerdings wird in diesem Fall der mit der ersten Nuss verbundene Hebel zum Zurückziehen der Falle sehr stark belastet, wenn man bei blockiertem Schloss versucht, den Drücker zu betätigen, sodass die Gefahr besteht, dass dieser Hebel bricht, speziell wenn die erste Nuss samt diesem Hebel aus Kunststoff hergestellt ist. Es ist somit oft sinnvoll, beide Blockierungen vorzusehen.In this case, the blocking of the first nut could be dispensed with, as it can not be twisted anyway in the case of a locked trap. However, in this case, the lever that is connected to the first nut to pull back the trap is very heavily loaded when trying to operate the pusher with locked lock, so that there is a risk that this lever breaks, especially if the first nut and this lever made of plastic. It is therefore often useful to provide both blocks.
Eine besonders einfache Konstruktion, die dennoch sehr hohe Kräfte aufnehmen kann, kann dadurch realisiert werden, dass der Verriegelungsteil zwischen den Schaft der Falle und den Schlosskasten schiebbar ist. In diesem Fall müsste der Schlosskasten deformiert werden, um die Falle entgegen der Blockierung zurück zu drücken.A particularly simple construction, which can still absorb very high forces, can be realized in that the locking part between the shaft of the case and the lock case is pushed. In this case, the lock case would have to be deformed to push the trap against the blockage back.
Gemäß einer speziellen Ausführungsform ist vorgesehen, dass die zweite Nuss eine im Wesentlichen quadratische Ausnehmung zur Aufnahme eines Vierkantstiftes aufweist, wobei an zumindest einer Seitenfläche, vorzugsweise an allen vier Seitenflächen, ausgehend von einer Flachseite der zweiten Nuss jeweils eine Nut vorgesehen ist. Damit kann nicht nur ein Verriegelungshebel eingesetzt werden (was auf der Innenseite üblich ist), sondern auf der Seite, von der die Nuten ausgehen, auch eine Art Schlüssel (was auf der Außenseite sinnvoll ist). Dieser Schlüssel ist im Wesentlichen ein Zapfen mit entweder einem Vorsprung am Ende (der in die eine Nut oder in eine der Nuten eingreift) oder mit zwei diametral gegenüberliegenden Vorsprüngen, die in gegenüberliegende Nuten eingreifen. In letzterem Fall werden die Kräfte symmetrisch in die zweite Nuss eingeleitet, wodurch sich diese leichter verdrehen lässt. Allerdings sieht solch ein Schlüssel mit zwei diametral gegenüberliegenden Vorsprüngen einem herkömmlichen Buntbartschlüssel weniger ähnlich.According to a specific embodiment, it is provided that the second nut has a substantially square recess for receiving a square pin, wherein in each case a groove is provided on at least one side surface, preferably on all four side surfaces, starting from a flat side of the second nut. Thus, not only a locking lever can be used (which is common on the inside), but on the side from which the grooves emanate, also a kind of key (which makes sense on the outside). This key is essentially a pin with either a projection on the end (which engages in one groove or in one of the grooves) or with two diametrically opposed projections which engage in opposite grooves. In the latter case, the forces are symmetrically introduced into the second nut, which makes it easier to twist. However, such a key with two diametrically opposed protrusions looks less like a conventional truncated key.
Wenn auf einer Seite ein Vierkant für einen Verriegelungshebel eingesteckt ist, dann ergibt sich dadurch für einen Schlüssel auf der anderen Seite automatisch ein Tiefenanschlag, auch wenn die Nuten von einer Flachseite der zweiten Nuss bis zur anderen Flachseite der zweiten Nuss durchgehen. Damit dieselbe Nuss aber auch verwendet werden kann, wenn kein Vierkant eingesetzt wird, ist es zweckmäßig, wenn die Nut bzw. die Nuten vor der Mittelebene der zweiten Nuss endet bzw. enden. Dadurch ergibt sich der Tiefenanschlag durch das Ende der Nuten. Diese Ausführung ist aber auch dann sinnvoll, wenn ein Vierkant eingesetzt wird, weil dann der Schlüssel nicht auf dem metallischen Vierkant aufschlägt, was einen für manche Personen unangenehmen Klang erzeugen würde. Ein Anschlag auf Kunststoff ist weicher und leiser.If a square for a locking lever is inserted on one side, then this results automatically for a key on the other side, a depth stop, even if the grooves pass from a flat side of the second nut to the other flat side of the second nut. But so that the same nut can also be used when no square is used, it is useful if the groove or grooves before the center plane of the second nut ends or end. This results in the depth stop through the end of the grooves. This version is also useful if a square is used, because then the key does not hit the metallic square, which would produce an unpleasant sound for some people. A stop on plastic is softer and quieter.
Wenn das Schloss von beiden Seiten mit einem Schlüssel ver- und entriegelt werden soll, dann ist auch ausgehend von der anderen Flachseite der zweiten Nuss an zumindest einer Seitenfläche, vorzugsweise an allen vier Seitenflächen, jeweils eine Nut vorzusehen, die vor der Mittelebene der zweiten Nuss endet.If the lock is to be locked and unlocked from both sides with a key, then starting from the other flat side of the second nut on at least one side face, preferably on all four side faces, one groove each is provided, which is in front of the center plane of the second nut ends.

Für dieses Schloss kann man weitestgehend Standardteile verwenden. So ist eine Falle 21 vorgesehen, die gleich wie bei den derzeit üblichen normgerechten Schlössern ausgebildet ist; sie ragt durch eine entsprechende Öffnung in einem Stulp 22 nach außen und weist einen Schaft 23 mit einem Vorsprung 23' an dessen freiem Ende auf. Die erste Nuss 13 weist einen Vorsprung 13' auf, der mit dem Vorsprung 23' zusammenwirkt, wodurch die Falle 21 durch Drehung der ersten Nuss 13 in das Innere des Schlosses zurückgezogen werden kann (siehe
Unterschiedlich zu einem Standardschloss sind die Ausbildung der ersten Nuss 13 und die Tatsache, dass an der Öffnung 19 die zweite Nuss 20 (s.
Die erste Nuss 13 hat eine teilzylindrische Ausnehmung 28 (siehe
Dieses Schloss ist also weitestgehend aus Standardteilen herstellbar, zusätzlich herzustellen sind nur die beiden Nüsse 13 und 20, und die können kostengünstig aus Kunststoff gefertigt werden. Im Übrigen könnte die Nuss 13 auch bei Standardschlössern eingesetzt werden, sodass nach einer entsprechenden Produktionsumstellung gegenüber diesen Standardschlössern überhaupt nur die zweite Nuss 20 zusätzlich benötigt wird. Will man ein Standardschloss herstellen, lässt man die zweite Nuss 20 weg, will man ein Schloss mit Blockiermöglichkeit herstellen, setzt man die zweite Nuss 20 ein. Somit sind die Kosten für das erfindungsgemäße Schloss mit Blockiermöglichkeit kaum höher als die Kosten für ein Standardschloss. Es ist lediglich ein Kunststoffteil zusätzlich einzusetzen.This lock is therefore largely produced from standard parts, in addition to produce only the two

Durch diese Nuten kann nun die zweite Nuss auf zweierlei Arten betätigt werden: Man kann einen Verriegelungshebel vorsehen, der mit einem Vierkant versehen ist, welcher in die quadratische Ausnehmung 32 eingreift.

Man kann aber auch eine Rosette mit einer Öffnung 36 vorsehen (siehe
