Abstract

The invention relates to a hook-lock, especially for computer cabinets, which is pivotable about a pivot axle to a closing and an opening position. Since previous locking mechanisms conventionally reach out and project from the corresponding main surface when in the opening position, according to the invention, the hook-lock is designed so as to be retractable completely within the main surface in the opening position. <IMAGE>

Description

Die Erfindung betrifft einen Schloßhaken, insbesondere für Computerschränke gemäß Oberbegriff des Anspruchs 1.The invention relates to a lock hook, in particular for computer cabinets according to the preamble of claim 1.

Derartige Schloßhaken werden vor allen Dingen in Computer­schränken, EDV-Mobiliar oder dergleichen eingesetzt, um eine zuverlässige feste Verriegelung zwischen den Türen und dem Schrankgestell zu ermöglichen, da häufig ein staubdichter und gegebenenfalls auch hochfrequenzsicherer Abschluß gegeben sein muß.
Bekannte Schloßhaken sind in ihrer Öffnungsstellung jedoch nur soweit verschwenkbar, daß der hakenförmige Bereich immer noch über die Hauptfläche des entsprechenden Gegenstandes z.B. der Tür oder der Computerschrankfläche hinausragt. Dieser aus der Hauptfläche hinausragende Bereich in der Öffnungsstellung stellt bei Montagearbeiten ein gewisses Hindernis, aber auch eine Beschädigungs- und Verletzungsstelle dar.
Lock hooks of this type are used above all in computer cabinets, computer furniture or the like, in order to enable reliable, firm locking between the doors and the cabinet frame, since a dust-tight and possibly also high-frequency-safe closure must often be provided.
Known lock hooks can only be pivoted so far in their open position that the hook-shaped area still protrudes beyond the main surface of the corresponding object, for example the door or the computer cabinet surface. This area protruding from the main surface in the open position represents a certain obstacle during assembly work, but also a point of damage and injury.

Des weiteren wird der Schloßhaken direkt in einer in der Tür oder dem Computerschrank bzw. deren Holmen vorgesehene Öffnung montiert. Die Montage der entsprechenden Kleinteile und Verbin­dungen erfordert daher bei der Komplettierung des Computer- bzw. EDV-Schrankes einen Zeitaufwand, der geeigneterweise in eine Vorstufe der Fertigung verlegt werden sollte. Vergleichbares gilt auch für Wartungs- und Reparaturarbeiten an dem bisher verwendeten Schloßhaken.Furthermore, the lock hook is mounted directly in an opening provided in the door or in the computer cabinet or its bars. The assembly of the corresponding small parts and connections therefore requires a time expenditure when completing the computer or EDP cabinet, which should suitably be moved to a preliminary stage of production. The same applies to maintenance and repair work on the lock hook previously used.

Ausgehend von diesen Nachteilen bei bisher bekannten Schloß­haken liegt daher der Erfindung die Aufgabe zugrunde, den Schloßhaken insgesamt gesehen so zu konzipieren, daß Ver­letzungs- und Beschädigungsmöglichkeiten am Schloßhaken in der Öffnungsstellung ausgeschlossen sind und gegebenenfalls seine Montage vereinfacht wird.Based on these disadvantages in previously known lock hooks, the object of the invention is to design the lock hook as a whole in such a way that possible injury and damage to the lock hook in the open position are excluded and possibly its assembly is simplified.

Diese Aufgabe wird erfindungsgemäß durch die Merkmale des kennzeichnenden Teils des Anspruchs 1 gelöst.This object is achieved by the features of the characterizing part of claim 1.

Ein wesentlicher Grundgedanke der Erfindung kann darin ge­sehen werden, den Schloßhaken mit seiner Außenkontur und in Anpassung an die Lage der Schwenkachse so zu gestalten, daß er in der Öffnungsstellung innerhalb der Außenfläche des ent­sprechenden Gegenstandes, z.B. des Tür- oder des Schrankholms, zu liegen kommt. Bezüglich einer montagemäßigen Vereinfachung geht man den Weg, den Schloßhaken einschließlich seiner Schloß­platte als vormontierte Baugruppe zu fertigen und kann dement­sprechend die Schloßplatte mit wenigen Handgriffen in der kom­plementären Öffnung der entsprechenden Tür- oder Schrankfläche befestigen. Geeigneterweise wird hierfür sogar nur eine Schraub­befestigung, z.B. im unteren Teil, gewählt, während im oberen Bereich der Schloßplatte ein hinterschnittener Nuteingriff vor­handen ist.An essential basic idea of the invention can be seen in designing the lock hook with its outer contour and in adaptation to the position of the pivot axis in such a way that in the open position it is inside the outer surface of the corresponding object, e.g. of the door or cupboard bar comes to rest. With regard to a simplification in terms of assembly, one goes the way to manufacture the lock hook including its lock plate as a preassembled module and can accordingly fasten the lock plate in the complementary opening of the corresponding door or cabinet surface in a few simple steps. Suitably, only a screw fastening, e.g. in the lower part, selected, while in the upper area of the lock plate there is an undercut slot.

Bei dieser Konzeption des Schloßhakens ist sozusagen sicherge­stellt, daß in geöffnetem Zustand eine ebene Hauptfläche der Tür- bzw. Computerschrankes vorliegt. Andererseits kann die vorgefertigte Baugruppe aus Schloßhaken und Schloßplatte sehr rasch im Türblatt bzw. der entsprechenden Verkleidung einge­setzt und befestigt werden, so daß diffizilere Arbeiten zur Be­festigung des eigentlichen Schloßhakens in der Schloßplatte fertigungstechnisch vorverlagert werden können.This design of the lock hook ensures, so to speak, that in the open state there is a flat main surface of the door or computer cabinet. On the other hand, the prefabricated assembly of the lock hook and lock plate can be inserted and fastened very quickly in the door leaf or the corresponding cladding, so that more difficult work for fastening the actual lock hook in the lock plate can be advanced in terms of production technology.

Der vorgenannte Schloßhaken ist generell gesehen mit zwei Ein­griffsöffnungen ausgestattet, von denen eine Eingriffsöffnung mit einer Betätigungseinrichtung, die z.B. als Schubstange aus­gebildet sein kann, in Wirkverbindung steht, um z.B. bei einer Vertikalverschiebung der Schubstange eine Schwenkbewegung des Schloßhakens und damit ein Öffnen bzw. Schließen desselben her­beizuführen. Der zweite Eingriffsbereich steht in der Schließ­stellung formschlüssig mit einem Schließ- oder Arretierzapfen in Verbindung, wobei hierdurch die eigentliche Arretierfunk­ tion erreicht wird.
Selbstverständlich kann der Schloßhaken in der Tür angebracht sein und die Arretierung durch den Eingriff mit einem Schließ­zapfen des Computerschrankes bzw. eines Holms vor sich gehen. Eine Umkehrung dieses Prinzips, also eine Halterung des Schloßhakens in einem Holm des Schrankes mit einem entspre­chenden Hakeneingriff in eine Tür ist ebenfalls denkbar.
The aforementioned lock hook is generally equipped with two engagement openings, of which one engagement opening is in operative connection with an actuating device, which can be designed, for example, as a push rod, in order, for example, to pivot the lock hook and thus open or close the same when the push rod is moved vertically bring about. In the closed position, the second engagement area is positively connected to a locking or locking pin, thereby the actual locking radio tion is reached.
Of course, the lock hook can be attached to the door and the locking can be done by engaging with a locking pin of the computer cabinet or a spar. A reversal of this principle, that is, a mounting of the lock hook in a spar of the cabinet with a corresponding hook engagement in a door is also conceivable.

Im Hinblick auf die Stabilität des Schloßhakens genügt im ein­fachsten Fall die Ausbildung des Schloßhakens als flächiges Stanzteil, wobei die erforderlichen Konturen und Öffnungen in einem Arbeitsprozeß erstellt werden können. Um den Eingriff mit der Betätigungseinrichtung günstiger zu gestalten, kann dieser Bereich des Schloßhakens auch gabelförmig ausgelegt sein. In dieser Ausführungsform kann die Verschwenkungskraft weitest­gehend senkrecht zur Schwenkachse aufgebracht werden und Schräg­kräfte auf den Schloßhaken vermieden werden.With regard to the stability of the lock hook, the simplest case is to design the lock hook as a flat stamped part, and the necessary contours and openings can be created in one work process. In order to make the engagement with the actuating device more favorable, this area of the lock hook can also be designed in the form of a fork. In this embodiment, the pivoting force can be applied largely perpendicular to the pivot axis and oblique forces on the lock hook can be avoided.

Da üblicherweise der Hakenbereich des Schloßhakens in der Schließstellung eine nach unten zeigende Öffnung aufweist, lie­gen die Eingriffsbereiche für die Schubstange und für den Schließ­zapfen zweckmäßigerweise oberhalb der Schwenkachse. Eine Umkeh­rung dieses Prinzips und sozusagen eine Erfassung des Schließ­zapfens von unten durch den Hakenbereich ist jedoch möglich.Since the hook area of the lock hook usually has an opening pointing downward in the closed position, the engagement areas for the push rod and for the locking pin are expediently above the pivot axis. However, a reversal of this principle and, so to speak, detection of the locking pin from below by the hook area is possible.

Um frühzeitig ein sicheres Erfassen des Schließzapfens zu ermög­lichen, weist der Hakenbereich eine Eingriffsschräge auf, die im Innenbereich eine weitgehend formschlüssige Kontur zum Schließ­zapfen hat, so daß die Schließstellung zuverlässig beibehalten werden kann. Um bei Schließ- und Öffnungsbewegung Reibungs­kräfte zwischen dem Schließzapfen und dem Hakenbereich zu ver­meiden, ist zweckmäßigerweise eine Rolle drehbar um den Schließ­zapfen angebracht, die jedoch axial fixiert ist. Die Rolle ge­stattet bei Berührung mit einer Schrägfläche des Hakenbereiches eine Drehbewegung am Schließzapfen, so daß Reibungskräfte weit­gehend vermieden werden. Zweckmäßigerweise geht die Eingriffs­schräge mit einer geringfügigen Hinterschneidung in den Innen­ bereich des Hakens über. Hierdurch erreicht man ein zuverlässi­ges Einrasten bzw. Einhaken des Schloßhakens um die Außenkontur der auf dem Schließzapfen befindlichen Rolle.In order to enable a secure grasping of the locking pin at an early stage, the hook area has an engagement slope which has a largely form-fitting contour for the locking pin in the inner area, so that the closed position can be reliably maintained. In order to avoid frictional forces between the locking pin and the hook area during the closing and opening movement, a roller is expediently rotatably attached around the locking pin, but is axially fixed. When in contact with an inclined surface of the hook area, the roller allows a rotary movement on the locking pin, so that frictional forces are largely avoided. The engagement slope expediently goes into the interior with a slight undercut area of the hook above. This results in a reliable locking or hooking of the lock hook around the outer contour of the roller located on the locking pin.

Der Eingriffsbereich des Schloßhakens für die Betätigungsein­richtung ist in der Schließstellung gesehen mit einem auf der Höhe der Schwenkachse angeordneten Hebel gestaltet, über den bei einer vertikalen Bewegung der Schubstange nach unten die Öff­nungskraft aufgebracht wird. Der obere Bereich dieses Eingriffs weist eine Schließbahnführung auf, über die bei einer vertikal nach oben gerichteten Bewegung der Schubstange der Schloßha­ken aus der Öffnungsstellung in die Schließstellung bringbar ist.The engagement area of the lock hook for the actuating device, when seen in the closed position, is designed with a lever arranged at the level of the pivot axis, by means of which the opening force is applied when the push rod is moved vertically downward. The upper area of this engagement has a closing track guide, by means of which the lock hook can be moved from the open position into the closed position when the push rod is moved vertically upward.

Die Schwenkachse des Schloßhakens ist geeigneterweise von der Außenkontur nach innen versetzt angeordnet, damit zumindest ein ausreichender Abstand zum Verschwenken und Versenken des Schloßhakens bzw. seines unteren Randes gegenüber der ent­sprechenden Außenkontur der Schloßplatte vorhanden ist. In der Schloßplatte ist eine schmale, längliche Öffnung vorge­sehen, die der Aufnahme des Schloßhakens mindestens über seine Länge zwischen der Schwenkachse und dem Hakenbereich dient. Der Eingriffsbereich des Schloßhakens für die Betätigungsein­richtung, wie eine Schubstange, kann so gestaltet sein, daß er in der Öffnungsstellung im Hohlraum z.B. der Tür zu liegen kommt. Im Hinblick auf eine günstige Verschwenkbarkeit und Ver­senkbarkeit des Schloßhakens in seiner Öffnungsstellung ist die Schwenkachse im unteren Bereich der Öffnung der Schloßplatte vorgesehen und die Kontur des unteren Randes einschließlich Ha­kenbereich des Schloßhakens so ausgebildet, daß kein Überstand über die Außenkontur bzw. Hauptfläche der Schloßplatte in der Öffnung vorhanden ist. Im Hinblick auf eine günstige Kraft­übertragung und Führung, aber auch eine zuverlässige Schließ­stellung sind die Eingriffsbereiche in der Lage der Schließ­stellung mit der Schubstange bzw. mit dem Schließzapfen zumin­dest partiell formschlüssig dazu gestaltet.The pivot axis of the lock hook is suitably arranged offset inwards from the outer contour, so that there is at least a sufficient distance for pivoting and sinking the lock hook or its lower edge relative to the corresponding outer contour of the lock plate. A narrow, elongated opening is provided in the lock plate, which serves to receive the lock hook at least over its length between the pivot axis and the hook area. The engagement area of the lock hook for the actuating device, such as a push rod, can be designed so that it comes to rest in the cavity, for example, the door in the open position. With regard to a favorable pivotability and retractability of the lock hook in its open position, the pivot axis is provided in the lower region of the opening of the lock plate and the contour of the lower edge including the hook region of the lock hook is designed so that there is no protrusion beyond the outer contour or main surface of the lock plate in the Opening is present. With regard to a favorable power transmission and guidance, but also a reliable closed position, the engagement areas in the position of the closed position with the push rod or with the locking pin are at least partially designed to be positive.

Die Erfindung wird nachstehend anhand einer schematischen Zeich­nung noch näher erläutert.The invention is explained in more detail below with the aid of a schematic drawing.

Die Figur zeigt einen Vertikalschnitt im Bereich einer Schloß­platte eines bruchstückartig dargestellten Schrankes, der mit­tels einer Tür und eines entsprechenden Schloßhakens verschließ­bar ist, wobei im wesentlichen die Details des Schloßhakens in seiner Schließstellung dargestellt sind.The figure shows a vertical section in the area of a lock plate of a fragmentary cabinet which can be locked by means of a door and a corresponding lock hook, the details of the lock hook being shown in its closed position.

Die Figur zeigt einen bruchstückartigen Vertikalschnitt durch eine Tür 14, die in einer geschlossenen Lage gegen­über einem Schrank 15 bzw. einem Holm desselben vorgesehen ist. Die Arretierung der Tür 14 gegenüber dem Schrank 15 wird im Beispiel durch einen im mittleren Bereich ange­ordneten Schloßhaken 1 realisiert, der in der gezeigten Schließstellung im wesentlichen horizontal angeordnet ist.The figure shows a fragmentary vertical section through a door 14 which is provided in a closed position opposite a cabinet 15 or a spar of the same. The locking of the door 14 with respect to the cabinet 15 is realized in the example by a lock hook 1 arranged in the central area, which is arranged essentially horizontally in the closed position shown.

Die Befestigung des Schloßhakens 1 in der Tür 14 erfolgt über eine Schloßplatte 10, die im oberen Bereich einen nut­artigen Hinterschnitt 21 für eine formschlüssige Plazierung gegenüber einer Nase 22 der Türverkleidung 17 und im unteren Bereich eine Überlappungszone 26 mit der Türverkleidung 17 aufweist.The lock hook 1 is fastened in the door 14 via a lock plate 10, which has a groove-like undercut 21 in the upper region for a form-fitting placement opposite a nose 22 of the door trim 17 and an overlap zone 26 with the door trim 17 in the lower region.

Die Schloßplatte 10 weist in einer Draufsicht von links (nicht dargestellt) eine schmale längliche Form auf, auf der im unteren Bereich zwei Stege 41 vorhanden sind, zwi­schen denen sich eine Ausnehmung erstreckt, die im oberen Teil in die Öffnung 12 übergeht. Im unteren Bereich dieser Öffnung ist versetzt in Richtung zu den Stegen 41 ein Bol­zen 2 bzw. Stift als Schwenkachse für den Schloßhaken 1 in der Schloßplatte befestigt. Um diesen Bolzen 2 ist der Schloßhaken 1 in seine Öffnungs- und Schließstellung auf­grund der Wirkverbindung mit einer in Vertikalrichtung be­tätigbaren Schubstange 6 bewegbar. Diese Schubstange 6 hat an ihrem oberen Ende einen im Schnitt kreisförmigen Mit­nehmer 13, der in Eingriff mit dem Öffnungsbereich 5 steht.In a top view from the left (not shown), the lock plate 10 has a narrow, elongated shape, on which there are two webs 41 in the lower region, between which a recess extends, which merges into the opening 12 in the upper part. In the lower area of this opening, a bolt 2 or pin is attached in the direction of the webs 41 as a pivot axis for the lock hook 1 in the lock plate. Around this bolt 2, the lock hook 1 can be moved into its open and closed position due to the operative connection with a push rod 6 which can be actuated in the vertical direction. This push rod 6 has at its upper end a driver 13 which is circular in section and which is in engagement with the opening region 5.

Die Betätigung der Schubstange 6 in vertikaler Richtung er­folgt beispielsweise über einen Betätigungsknopf 38 und eine angedeutete Achse 39, die einen Schnecken- oder Zahn­stangeneingriff mit der Schubstange 6 zu deren Vertikal­verschiebung aufweist. Der Betätigungsknopf 38 ist auf der Außenseite der äußeren Türverkleidung 16 angebracht.The push rod 6 is actuated in the vertical direction, for example, via an actuating button 38 and an indicated axis 39, which has a worm or rack engagement with the push rod 6 for its vertical displacement. The actuation button 38 is attached to the outside of the outer door trim 16.

Der Eingriffsbereich 5, der stets im Hohlraum der Tür 14 zu liegen kommt, weist in der Schließstellung eine halb­nierenförmige Öffnung auf, die zur Schloßplatte 10 hin eine weitgehend formschlüssige Rundung 19 für die Aufnah­me des Mitnehmers 13 hat. Im unteren Bereich ist ein etwa horizontal vom Bolzen 6 nach links ragender Hebelarm 32 vorgesehen. Der obere Bereich des Eingriffsbereichs wird durch eine Schließbahnführung 33 gebildet.The engagement area 5, which always comes to rest in the cavity of the door 14, has a semi-kidney-shaped opening in the closed position, which has a largely form-fitting curve 19 for receiving the driver 13 towards the lock plate 10. A lever arm 32, which projects approximately horizontally from the bolt 6 to the left, is provided in the lower region. The upper area of the engagement area is formed by a closing track guide 33.

In der gezeigten Schließstellung ragt etwa horizontal aus der Schloßplatte 10 der Hakenbereich 3 heraus. Dieser Ha­kenbereich 3 umgreift in der gezeigten Schließstellung formschlüssig einen im Innenbereich 9 zu liegen kommenden Schließzapfen 4. Die Öffnung 7 des Hakenbereiches ist nach unten etwa dreieckförmig geöffnet, so daß eine Eingriffs­schräge 8 zur leichteren Erfassung des runden Schließ­zapfens 4 bei der Schließbewegung erreicht wird.In the closed position shown, the hook area 3 protrudes approximately horizontally from the lock plate 10. In the closed position shown, this hook area 3 positively encompasses a locking pin 4 to be located in the inner area 9. The opening 7 of the hook area is approximately triangularly opened downward, so that an engagement bevel 8 for easier detection of the round locking pin 4 is achieved during the closing movement.

Auf dem Schließzapfen 4 ist eine drehbare Rolle 28 vorge­sehen, die in axialer Richtung fixiert ist. Die Außenkon­tur dieser Rolle 28 liegt in der Schließstellung form­schlüssig gegen den Innenbereich 9 des Hakenbereichs. Hier­bei ist am Übergang zur Eingriffsschräge 8 eine geringfü­gige Hinterschneidung 29 des Innenbereichs vorgesehen, um ein sicheres Einrasten des Schloßhakens 1 in der Schließ­ stellung zu erreichen. Mit anderen Worten erstreckt sich der formschlüssige Innenbereich 9 im Beispiel etwa über einen Winkelbereich von 200°. Die Hinterschneidung 29 ist so gewählt, daß eine geringfügig höhere Kraft das Einrasten der Rolle 28 im Innenbereich 9 des Hakenbereichs gestattet. Die Rolle 28 selbst bewirkt, daß Reibungskräfte bei der Schließ- und Öffnungsbewegung kaum vorhanden sind, da beim Erfassen mit der Eingriffsschräge 8 bzw. der Hinterschnei­dung 29 eine Drehbewegung der Rolle 28 einsetzt.A rotatable roller 28 is provided on the locking pin 4 and is fixed in the axial direction. The outer contour of this roller 28 lies in the closed position in a form-fitting manner against the inner region 9 of the hook region. Here, at the transition to the engagement slope 8, a slight undercut 29 of the inner region is provided in order to securely engage the lock hook 1 in the lock to achieve position. In other words, the form-fitting inner region 9 in the example extends approximately over an angular range of 200 °. The undercut 29 is selected so that a slightly higher force allows the roller 28 to snap into the inner region 9 of the hook region. The roller 28 itself has the effect that there are hardly any frictional forces during the closing and opening movement, since a rotation of the roller 28 begins when the engagement bevel 8 or the undercut 29 is gripped.

Der unsere Rand 35 des Schloßhakens 1 ist im Bereich der Öffnung 12 etwa horizontal verlaufend und hat einen schräg nach oben gehenden Übergang in die Öffnung 7 des Hakenbe­reichs 3.Our edge 35 of the lock hook 1 extends approximately horizontally in the area of the opening 12 and has an obliquely upward transition into the opening 7 of the hook area 3.

Montagemäßig kann daher der Schloßhaken 1 der bereits über dem Bolzen 2 in der Schloßplatte 10 vormontiert ist, mit formschlüssigen Eingriff im oberen Teil und einer Über­lappung im unteren Teil in einfacher Weise in die innere Türverkleidung 17 eingesetzt werden und beispielsweise mittels einer Schraube durch die Befestigungsöffnung 25 in der Tür befestigt werden.In terms of assembly, the lock hook 1, which is already pre-assembled above the bolt 2 in the lock plate 10, can be inserted into the inner door trim 17 in a simple manner with positive engagement in the upper part and an overlap in the lower part, and for example by means of a screw through the fastening opening 25 be fastened in the door.

Die Öffnungskraft wird im vorliegenden Beispiel durch eine Verschiebung der Schubstange 6 etwa vertikal nach unten durch deren Mitnehmer 13, der parallel zur Schwenkachse im Bolzen 2 verläuft, aufgebracht. Der Mitnehmer 13 erfaßt dabei den Hebelarm 32, so daß dieser nach unten verschwenkt wird. Gleichzeitig gelangt der Hakenbereich 3 außer Ein­griff mit dem Schließzapfen 4. Diese Verschwenkung erfolgt über einen Bereich von etwa 90°, so daß in der vollen Öff­nungsstellung der gesamte Hakenbereich 3 und der untere Rand 35 des Schloßhakens 1 innerhalb der Öffnung 12 und der Außenfläche 11, die die dem Gehäuseholm 15 zugewandte Fläche darstellt, zu liegen kommt.The opening force is applied in the present example by a displacement of the push rod 6 approximately vertically downwards by its driver 13, which runs parallel to the pivot axis in the bolt 2. The driver 13 detects the lever arm 32 so that it is pivoted downward. At the same time, the hook area 3 disengages from the locking pin 4. This pivoting takes place over a range of approximately 90 °, so that in the fully open position the entire hook area 3 and the lower edge 35 of the lock hook 1 within the opening 12 and the outer surface 11, which represents the surface facing the housing spar 15 comes to rest.

Die Schließkraft wird durch eine Aufwärtsbewegung der Schubstange auf die Schließbahnführung 33 aufgebracht, wo­bei in der gezeigten Schließstellung der Schließzapfen 4 partiell formschlüssig in der Öffnung 7 des Hakenbereichs aufgenommen ist.The closing force is applied to the closing track guide 33 by an upward movement of the push rod, the closing pin 4 being partially received in a form-fitting manner in the opening 7 of the hook area in the shown closed position.

Die Konzeption des plattenförmigen Schloßhakens als Bau­gruppe mit der Schloßplatte 10 gestattet daher eine ein­fache, unkomplizierte Montage und zudem eine vollständige Versenkung des Schloßhakens innerhalb der Außenfläche der Tür 14.The design of the plate-shaped lock hook as an assembly with the lock plate 10 therefore allows simple, uncomplicated assembly and also a complete sinking of the lock hook within the outer surface of the door 14.
