Abstract
Description
Die Erfindung betrifft ein Einsteckschloß, insbesondere für Innen- und Wohnungsabschlußtüren.The invention relates to a mortise lock, in particular for interior and apartment doors.
Solche Einsteckschlösser sind allgemein bekannt. Sie umfassen eine aus Schloßkasten, Schloßdecke und Stulp bestehende feste Umhausung, in welcher die beweglichen Schloßteile, wie z. B. Riegel, Falle, Nuß usw. mit Spielpassung gelagert sind. Durch Einwirkung äußerer Kräfte, insbesondere bei der Befestigung der Schlösser in den Schloßtaschen der Türen, können Kräfte, die von außen, vor allem als Querkräfte auf den Schloßkasten und die Schloßdecke einwirken und diese etwas verformen, die Spielpassungen beeinträchtigen, und dadurch die Funktion des Schlosses stören oder ganz unmöglich machen.Such mortise locks are generally known. They include a fixed housing consisting of a lock case, lock cover and faceplate, in which the movable lock parts, such as. B. bolts, latch, nut, etc. are stored with a clearance fit. Through the action of external forces, particularly when fastening the locks in the lock pockets of the doors, forces which act on the lock case and the lock cover from outside, especially as transverse forces, and deform them somewhat, can impair the fit of the game and thereby the function of the lock disturb or make it impossible.
Dieses Problem ist bei Einsteckschlössern für Türen, die mit Rosettenbeschlägen ausgestattet sind, besonders akut, weil die Schloßtaschenwände bei Innentüren und Wohnungsabschlußtüren relativ dünn sind, und die als Beschläge verwendeten Rosetten beim Anschrauben auf eine relativ kleine Fläche drükken, wodurch die Schloßtaschenwände selbst verformt werden und auf den Schloßkasten und die Schloßdecke drücken und zu Verformungen führen können, die die Funktion des Schlosses stören oder blockieren. Wenn ein größeres Spiel zwischen den Außenflächen von Schloßkasten und Schloßdecke und den Innenflächen der Schloßtaschenwände vorhanden ist, wie dies zum problemlosen Ein- und Ausbau der Schlösser erwünscht ist, besteht zusätzlich die Gefahr, daß die Schloßtaschenwände beim Anschrauben der Rosetten einbrechen, insbesondere bei Verwendung von Schraubern mit zu hoch eingestelltem Drehmoment oder bei gefühllosem Anziehen der Schrauben mittels Schraubendreher.This problem is particularly acute for mortise locks for doors which are equipped with rosette fittings, because the lock pocket walls for interior doors and apartment doors are relatively thin, and the rosettes used as fittings press onto a relatively small area when screwed on, as a result of which the lock pocket walls themselves are deformed and press on the lock case and the lock cover and can lead to deformations that disrupt or block the function of the lock. If there is a greater play between the outer surfaces of the lock case and the lock cover and the inner surfaces of the lock pocket walls, this can be done without problems Installation and removal of the locks is desired, there is also the risk that the lock pocket walls collapse when screwing on the rosettes, especially when using screwdrivers with a torque that is set too high or when the screws are tightened without feeling using a screwdriver.
Um die Verformung der Schloßdecke relativ zum Schloßkasten zu verhindern und dadurch die Spielpassungstoleranzen der zwischen Schloßdecke und Schloßkastenboden gelagerten beweglichen Bauteile zu gewährleisten, ist es bei Schlössern mit angeschraubter Schloßdecke seit langem bekannt, an den Verschraubungsstellen zwischen den Innenflächen von Schloßdecke und Schloßkasten Stützpfeiler oder Stützbuchsen vorzusehen, und in die Flächen von Schloßdecke und Schloßkasten zur Versteifung Sicken und Verrippungen einzupressen.In order to prevent the deformation of the lock cover relative to the lock case and thereby to ensure the clearance tolerances of the movable components mounted between the lock cover and the lock case bottom, it has long been known in locks with a screwed lock cover to provide support pillars or support bushes at the screwing points between the inner surfaces of the lock cover and lock case , and to press beads and ribs into the surfaces of the lock cover and lock case for reinforcement.
Aus der DE-U 29 509 864.3 ist es weiterhin bekannt, mindestens ein zusätzliches, den Schloßkastenboden gegenüber der Schloßdecke beabstandetes Stützteil anzuordnen, welches auch aus dem Schloßkasten und der Schloßdecke nach außen vorstehen kann, um die Wände der Schloßtasche abzustützen und das Zusammendrücken der Schloßtasche zu vermindern bzw. deren Einbrechen zu verhindern. Obwohl die Stützbuchsen und -pfeiler sowie die zusätzlich angeordneten Stützteile nach DE-U 29 509 864.3 in den Bereichen, in denen sie die Funktion der beweglichen Bauteile nicht behindern, einen ausgezeichneten Schutz gegen eine relative Verformung der Schloßdecke gegenüber dem Schloßkastenboden darstellen, und die nach DE-U 29 509 864.3 eingesetzten zusätzlichen Stützteile, wenn sie nach außen vorstehen, sogar die Gefahr des Einbrechens der Schloßtasche weitgehend verhindern können, ist deren Anordnung an einigen Stellen innerhalb des Schlosses aus Platzgründen nicht möglich. Eine solche Stelle ist z. B. der Schließbereich des Schlosses, in welchem genügend Platz zum Durchdrehen des Schlüsselbartes bzw. des Schließbartes des Profilzylinders verbleiben muß.From DE-U 29 509 864.3 it is also known to arrange at least one additional support part which is spaced apart from the lock case base in relation to the lock cover and which can also protrude outward from the lock case and the lock cover in order to support the walls of the lock pocket and to compress the lock pocket to reduce or prevent their collapse. Although the support bushings and pillars as well as the additionally arranged support parts according to DE-U 29 509 864.3 in the areas in which they do not hinder the function of the movable components represent excellent protection against a relative deformation of the lock cover relative to the lock case base, and according to DE-U 29 509 864.3 used additional support parts, if they protrude outwards, can even largely prevent the risk of the lock pocket breaking in, their arrangement at some points within the lock is not possible for reasons of space. Such a place is e.g. B. the locking area of the lock, in which enough space must remain to turn the key bit or the bit of the profile cylinder.
Gerade dieser Bereich ist jedoch gegen Verformungen besonders gefährdet, weil auch hier vielfach als Türbeschläge Rosetten zum Einsatz kommen, und deren Befestigung durch Verspannung der vorderen und der hinteren Rosette gegen die Außenflächen des Türblattes erfolgt. Bei diesem Verspannen kann es, wie erwähnt, infolge zu hoher Voreinstellung des Schrauber-Drehmomentes oder durch gefühlloses Anziehen mittels Schraubendreher zu einem relativ hohen Druck zwischen den Rosetten, der auf das Türblatt ausgeübt wird, kommen. Da im Schließbereich des Schlosses die bekannten zusätzlichen Abstützungen nicht angewendet werden können, kann der zwischen den Rosetten auf der Schloßtasche ausgeübte hohe Druck dazu führen, da sich die Schloßdecke und der Schloßkasten relativ zueinander verformen. Dadurch kann nicht nur die Funktion des Schlosses beeinträchtigt oder blockiert werden, sondern es kann auch zu einer solchen Deformation der Schloßtaschen kommen, daß die Deckschichten des Türblattes im Schloßbereich einbrechen und die gesamte Tür unbrauchbar machen. Letztere Gefahr wird noch verstärkt, wenn die Schloßtaschen relativ zur Dicke des Schlosses einen positiven Toleranzbereich besitzen, was vorteilhaft ist, um das Schloß problemlos in die Schloßtasche einschieben zu können. Zwischen den Innenflächen der Schloßtasche und den Außenflächen des Schlosses besteht demnach ein mehr oder weniger großer Abstand, der bei unsachgemäßer Verspannung der Rosetten zunächst zusammengedrückt wird, bevor der Druck auf Schloßkasten und Schloßdecke wirkt. Dadurch sind die Deckschichten des Türblattes gegen Einbruch gerade im Schließbereich, weil hier die zusätzlichen Abstützungen nach DE-U 29 509 864.3 nicht zum Einsatz kommen können, besonders gefährdet.However, this area in particular is particularly at risk of deformation, because rosettes are often used here as door fittings, and they are fastened by bracing the front and rear rosette against the outer surfaces of the door leaf. This tensioning can, as mentioned, due to excessive presetting of the screwdriver torque or by senseless tightening with a screwdriver, a relatively high pressure between the rosettes, which is exerted on the door leaf. Since the known additional supports cannot be used in the lock area of the lock, the high pressure exerted between the rosettes on the lock pocket can result in the lock cover and the lock case deforming relative to one another. This can not only impair or block the function of the lock, but it can also lead to such deformation of the lock pockets that the cover layers of the door leaf collapse in the lock area and render the entire door unusable. The latter danger is exacerbated if the lock pockets have a positive tolerance range relative to the thickness of the lock, which is advantageous in order to be able to insert the lock into the lock pocket without problems. There is therefore a more or less large distance between the inner surfaces of the lock pocket and the outer surfaces of the lock, which is pressed together if the rosettes are improperly tightened before the pressure acts on the lock case and lock cover. As a result, the cover layers of the door leaf are particularly at risk of burglary in the closing area because the additional supports according to DE-U 29 509 864.3 cannot be used here.
Es ist deshalb Aufgabe der Erfindung, ein Einsteckschloß zu entwickeln, bei dem die Gefahr des Einbruches der Deckschichten des Türblattes beim Anschrauben der Rosetten weiter vermindert und die Möglichkeit zur relativen Verformung von Schloßkasten und Schloßdecke zueinander auch im Schließbereich wesentlich eingeschränkt wird.It is therefore an object of the invention to develop a mortise lock in which the risk of the cover layers of the door leaf collapsing when the rosettes are screwed on is further reduced and the possibility of relative deformation of the lock case and lock cover to one another is also substantially restricted in the closing area.
Die Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des Schutzanspruches 1 gelöst. Vorteilhafte Ausführungsformen der Erfindung sind Kennzeichen der Unteransprüche.The object is achieved by the characterizing features of claim 1. Advantageous embodiments of the invention are characteristic of the subclaims.
Die Erfindung soll im folgenden anhand eines Ausführungsbeispieles in Verbindung mit den Figuren 1 bis 4 näher erläutert werden.
- Figur 1 zeigt ein erfindungsgemäßes Einsteckschloß in perspektivischer Darstellung;
- Figur 2 zeigt ein erfindungsgemäßes Einsteckschloß in Draufsicht, in Seitenansicht sowie in einer Schnittansicht in Richtung der Pfeile A-A;
- Figur 3 zeigt eine besondere Ausführungsform eines Stützteiles für den Drückerbereich; und
- Figur 4 zeigt ein Beispiel einer erfindungsgemäßen Schloßtaschenabstützung für den Schließbereich in vergrößertem Maßstab.
- Figure 1 shows a mortise lock according to the invention in a perspective view;
- Figure 2 shows a mortise lock according to the invention in plan view, in side view and in a sectional view in the direction of arrows AA;
- FIG. 3 shows a special embodiment of a support part for the pusher area; and
- Figure 4 shows an example of a lock pocket support according to the invention for the locking area on an enlarged scale.
In Figur 1 ist ein erfindungsgemäßes Einsteckschloß in perspektivischer Ansicht dargestellt. Das Schloß umfaßt den Schloßkasten 3, und eine Schloßdecke 4, zwischen denen die beweglichen Bauteile, z. B. eine Falle 6 und ein Riegel 8 drehbar bzw. verschieblich gelagert sind. Das Schloß umfaßt auch ein bekanntes, den Schloßkastenboden gegenüber der Schloßdecke beabstandendes Stützteil 1, das mit Endteilen 17, 18 versehen ist, welche durch Durchbrüche im Schloßkastenboden und in der Schloßdecke hindurchragen, und dadurch die Innenflächen der Schloßtaschenwände gegeneinander abstützen können. Das bekannte Stützteil 1 ist, wie die Figur 3 zeigt, so geformt, daß es auch als dachartige Abschirmung gegen das Eindringen eventuell von oben herabfallender Späne in das Riegelsystem dient.In Figure 1, a mortise lock according to the invention is shown in perspective view. The lock includes the lock case 3, and a lock cover 4, between which the moving components, e.g. B. a latch 6 and a bolt 8 are rotatably or slidably mounted. The lock also includes a known, the lock case base spaced from the lock cover supporting part 1, which is provided with end parts 17, 18 which protrude through openings in the lock case base and in the lock cover, and thereby can support the inner surfaces of the lock pocket walls against each other. As is shown in FIG. 3, the known support part 1 is shaped in such a way that it also serves as a roof-like shield against the ingress of chips falling into the locking system from above.
Beim Einbau der Schlösser wird nämlich vor dem Bohren der erforderlichen Beschlagsdurchbrüche in den Schloßtaschenwänden nur in den seltensten Fällen das Schloß wieder ausgebaut. Dabei können beim Bohren der Beschlagsdurchbrüche im Bereich der Schloßnuß Späne in das Schloß gelangen und in das Riegelsystem fallen, wo sie die Funktion des Schlosses stören oder behindern können. Durch die besondere Gestaltung des Stützteiles 1 als dachartige Abschirmung, wie dies in Figur 3 dargestellt ist, kann das Eindringen von Spänen in das Riegelsystem beim Bohren der Beschlagsdurchbrüche verhindert werden.When installing the locks, the lock is only removed in the rarest of cases before drilling the required hardware openings in the lock pocket walls. When drilling the hardware breakthroughs in the area of the lock nut, chips can get into the lock and fall into the locking system, where they can disrupt or hinder the function of the lock. The special design of the support part 1 as a roof-like shield, as shown in FIG. 3, prevents chips from penetrating into the locking system when drilling through the fittings.
Das Schloß umfaßt weiterhin eine erfindungsgemäße Schloßtaschenabstützung 30, die an einer Seitenwand 31 des Schloßkastens 3, welche sich in der Nähe des Schließbereiches des Schlosses befindet, außen befestigt ist. Die Schloßtaschenabstützung 30 ist dabei so angeordnet, daß deren Höhenausdehnung HS (siehe Figur 2) parallel zur Höhenausdehnung H des Stützteiles 1 verläuft.The lock further comprises a lock pocket support 30 according to the invention, which is fastened to the outside on a side wall 31 of the lock case 3, which is located in the vicinity of the locking area of the lock. The lock pocket support 30 is arranged in such a way that its height expansion HS (see FIG. 2) runs parallel to the height expansion H of the support part 1.
In Figur 1 ist auch angedeutet, daß die Rosetten 40 mittels (nicht dargestellter) Schrauben durch Durchbrüche 41 in Schloßdecke und Schloßkastenboden hindurch mit (nicht dargestellten) Gegenrosetten, die mit entsprechenden Innengewinden versehen sind, verschraubt werden. Während die Schloßtaschen und Schlösser schon bisher im Bereich der Nuß durch das Stützteil 1 mit seinen durch die Durchbrüche von Schloßkastenboden und Schloßdecke hindurchragenden Endteilen 17, 18 gegen Verformung weitgehend geschützt waren, schafft im Schließbereich erst eine erfindungsgemäße Schloßtaschenabstützung 30 Abhilfe.In Figure 1 is also indicated that the rosettes 40 by means of (not shown) screws through openings 41 in the lock cover and lock case bottom with (not shown) counter rosettes, which are provided with corresponding internal threads, screwed. While the lock pockets and locks were previously largely protected against deformation in the area of the nut by the support part 1 with its end parts 17, 18 protruding through the openings in the lock case base and lock cover, a lock pocket support 30 according to the invention only remedies in the locking area.
In Figur 2 ist die bevorzugte Ausführungsform eines erfindungsgemäßen Einsteckschlosses in Draufsicht (in welcher die Schloßdecke entfernt ist) sowie in Seitenansicht und in einer Schnittansicht A-A dargestellt.FIG. 2 shows the preferred embodiment of a mortise lock according to the invention in a top view (in which the lock cover is removed) and in a side view and in a sectional view A-A.
In der Schnittansicht A-A wurden alle für das Verständnis der Erfindung unwesentlichen Teile im Schloß weggelassen.In the sectional view A-A, all parts which are not essential for the understanding of the invention have been left out of the lock.
In der Draufsicht der Figur 2 ist gut erkennbar, wie zwei Befestigungselemente 33 der Schloßtaschenabstützung 30 in der Seitenwand 34 des Schloßkastens 3 verschieblich befestigt sind. Die Befestigungselemente 33 bestehen aus laschenartigen Fußteilen 35, die eine Länge aufweisen, die der Blechdicke der Seitenwand 34 des Schloßkastens 3 entspricht, sowie Kopfteilen 36, die am oberen Ende der Fußteile 35 abgewinkelt angeordnet sind. Die Fußteile 35 der Schloßtaschenabstützung 30 werden vor dem Aufsetzen der Schloßdecke in die in die Seitenwand des Schloßkastens 3 eingebrachten, nach oben hin offenen Schlitze 37 eingeschoben. Die seitlich abgewinkelten Kopfteile 36 verhindern ein seitliches Herausrutschen der Fußteile 35 aus den Schlitzen 37. Nach Aufsetzen der Schloßdecke 4 wird auch ein Herausrutschen der Schloßtaschenabstützung 30 aus den nach oben hin offenen Schlitzen 37 verhindert. Statt der in den Figuren 2 und 4 erkennbaren abgewinkelten Kopfteile 36 kann das Befestigungsteil auch beiseitig überkragende oder anderweitig verdickte Kopfteile 36 besitzen, die ebenfalls die Fußteile in den Schlitzen verschieblich halten. Durch die verschiebliche Anordnung der Schloßtaschenabstützung 30 wird eine Überbestimmung der Lage des Schlosses relativ zur Position der Schloßtasche vermieden. Die Schloßtaschenabstützung 30 verhindert wirksam ein Zusammendrücken der Schloßtasche beim Anziehen der Befestigungsschrauben für die Rosetten. Für die richtige Lage des Schlosses in der Schloßtasche des Türblattes sorgen jedoch ausschließlich das Stützteil 1 mit den durch den Schloßkastenboden und die Schloßdecke hindurchragenden Endteilen 17, 18, welche die Außenseiten des Schloßkastenbodens und der Schloßdecke in einem bestimmten Abstand von den Innenwänden der Schloßtasche halten, sowie die Befestigung des Stulpes. Die Schloßtaschenabstützung 30 hält infolge ihrer verschieblichen Anordnung lediglich die Schloßtaschenwände auf Abstand, bewirkt aber im Gegensatz zum Stützteil 1 keine Festlegung eines bestimmten Abstandes der Außenseiten des Schloßkastenbodens und der Schloßdecke zu den Innenwänden der Schloßtasche. Somit wird vermieden, daß durch eine Überbestimmung bei der Festlegung der Lage des Schlosses in der Schloßtasche irgendwelche Biegemomente auf den Schloßkasten und die Schloßdecke ausgeübt werden, die ebenfalls zu Funktionsstörungen der zwischen Schloßdecke und Schloßkastenboden gelagerten beweglichen Bauteile führen könnten.In the plan view of FIG. 2 it can be clearly seen how two fastening elements 33 of the lock pocket support 30 are slidably fastened in the side wall 34 of the lock case 3. The fastening elements 33 consist of tab-like foot parts 35, which have a length that corresponds to the sheet thickness of the side wall 34 of the lock case 3, and head parts 36, which are arranged at the upper end of the foot parts 35 at an angle. The foot parts 35 of the lock pocket support 30 are inserted into the side wall of the lock case 3, slots 37 which are open at the top and are inserted before the lock cover is put on. The laterally angled head parts 36 prevent the foot parts 35 from slipping out of the slots 37. After the lock cover 4 has been put on, the lock pocket support 30 is prevented from slipping out of the slots 37 which are open towards the top. Instead of the angled head parts 36 which can be seen in FIGS. 2 and 4, the fastening part can also have head parts 36 which protrude on both sides or which are otherwise thickened and which likewise keep the foot parts displaceable in the slots. The displaceable arrangement of the lock pocket support 30 avoids overdetermining the position of the lock relative to the position of the lock pocket. The lock pocket support 30 effectively prevents the lock pocket from being compressed when the fastening screws for the rosettes are tightened. For the correct position of the castle in the lock pocket of the door leaf, however, only the support part 1 with the end parts 17, 18 projecting through the lock case base and the lock cover, which hold the outside of the lock case base and the lock cover at a certain distance from the inner walls of the lock pocket, and the fastening of the cuff. The lock pocket support 30 only keeps the lock pocket walls at a distance due to its displaceable arrangement, but, in contrast to the support part 1, does not result in a specific distance between the outside of the lock case bottom and the lock cover from the inner walls of the lock pocket. This avoids that due to an over-determination when determining the position of the lock in the lock pocket any bending moments are exerted on the lock case and the lock cover, which could also lead to malfunctions of the movable components stored between the lock cover and the lock case bottom.
In Figur 4 ist eine bevorzugte Ausführungsform der Schloßtaschenabstützung 30 in vergrößertem Maßstab in vier Ansichten dargestellt. Am im wesentlichen quaderförmigen Körper 31 der Schloßtaschenabstützung 30 sind die Fußteile 35 angeordnet, die eine Länge 1 aufweisen, die etwa der Blechdicke der Seitenwand 34 des Schloßkastens 3 entspricht. Anschließend an die Länge 1 des Fußteiles sind abgewinkelte oder verdickte Kopfteile 36 angeordnet, welche die Fußteile in den als Schlitze in der Seitenwand 34 des Schloßkastens 3 ausgebildeten Befestigungsöffnungen 37 festhalten. Die Fußteile 35 besitzen eine Höhe h, die größer ist als ihre Breite b, jedoch kleiner als etwa die Hälfte der Gesamthöhe der Seitenwand 34 des Schloßkastens 3. Dadurch sind die Fußteile 35 in den als Schlitze ausgebildeten Befestigungsöffnungen 37 verschieblich, und halten dadurch nur die Innenseiten der Schloßtaschenwände auf Abstand, bestimmen aber nicht die Abstände zwischen den Außenseiten von Schloßkastenboden und Schloßdecke sowie den Innenseiten der Schloßtaschenwände.FIG. 4 shows a preferred embodiment of the lock pocket support 30 on an enlarged scale in four views. On the substantially cuboid body 31 of the lock pocket support 30, the foot parts 35 are arranged, which have a length 1, which corresponds approximately to the sheet thickness of the side wall 34 of the lock case 3. Following the length 1 of the foot part, angled or thickened head parts 36 are arranged, which hold the foot parts in the fastening openings 37 designed as slots in the side wall 34 of the lock case 3. The foot parts 35 have a height h which is greater than their width b, but less than about half the total height of the side wall 34 of the lock case 3. As a result, the foot parts 35 are displaceable in the fastening openings 37 in the form of slots, and thereby hold only those The inside of the lock pocket walls are spaced apart, but they do not determine the distances between the outside of the lock case base and lock cover and the inside of the lock pocket walls.
Um das Gleiten der Schloßtaschenabstützung 30 beim Einschieben des Schlosses in die Schloßtasche zu erleichtern, sind die Längs- und Querkanten 51, 52 des Körpers 31 abgefast oder abgerundet.In order to facilitate the sliding of the lock pocket support 30 when the lock is pushed into the lock pocket, the longitudinal and transverse edges 51, 52 of the body 31 are chamfered or rounded.
Die Schloßtaschenabstützung 30 wird vorzugsweise einstückig aus Kunststoff hergestellt, wobei als Kunststoff vorzugsweise Polyamid verwendet wird, der auch durch Beimischung, z. B. von Glasfasern verstärkt sein kann. Vorzugsweise werden dem Kunststoff etwa 20 % Glasfasern beigemischt.The lock pocket support 30 is preferably made in one piece from plastic, polyamide being preferably used as the plastic also by admixture, e.g. B. can be reinforced by glass fibers. Preferably about 20% glass fibers are added to the plastic.
