Both bolts are tensioned in their closed position by a spring device (32).

Description

Die Erfindung betrifft einen Schrank mit Wenigstens einem Schubladenelement, das in eingeschobener Schließstellung verriegelbar ist, mit einem an der Schublade angeordneten Verriegelungsmechanismus, der über einen im Rückwandbereich der Schublade vorgesehenen Riegel und einen Betätigungsmechanismus für den Riegel verfügt, und mit einem im Rückwandbereich der Schublade an der Schrankkonstruktion angeordneten Riegelschloß, in das der Riegel in Schließstellung der Schublade eingreift.The invention relates to a cabinet with at least one drawer element, which can be locked in the inserted closed position, with a locking mechanism arranged on the drawer, which has a latch provided in the rear wall area of the drawer and an actuating mechanism for the latch, and with one in the rear wall area of the drawer bolt lock arranged in the cabinet construction, in which the bolt engages in the closed position of the drawer.

Bei derartigen Schränken werden die Schubladen in eingeschobener Stellung zwangsverriegelt. Die Schubladenschränke mit Zwangsverriegelung finden vor allem für Schränke im mobilen Einsatz, z.B. für Werkstattwagen, Verwendung. Bislang werden die Schubladen mittels eines Riegels im Rückwandbereich gehalten, der in ein an der Schrankkonstruktion vorgesehenes Riegelschloß eingreift. Durch den mobilen Einsatz ist der Schrank großen Trägheitskräften unterworfen, die beim Beschleunigen und Abbremsen des Wagens auftreten. Dies führte bei den bislang bekannten Schränken bisweilen zu einem Aufbrechen des Mechanismus und Herausschleudern der Schublade samt Inhalt. Bei Werkstattwagen sind die Schubladen in der Regel mit relativ schweren Gegenständen befrachtet, so daß eine sich lösende Schublade während der Fahrt einen großen Schaden im Innenbereich des Werkstattwagens anrichten und den Fahrer gefährden kann.With such cabinets, the drawers are positively locked in the inserted position. The drawer cabinets with positive locking are mainly used for cabinets in mobile use, e.g. for workshop trolleys, use. So far, the drawers have been held in the rear wall area by means of a bolt which engages in a bolt lock provided on the cabinet construction. Due to the mobile use, the cabinet is subject to large inertia forces that occur when the car accelerates and brakes. With the previously known cabinets, this sometimes led to the mechanism being broken open and the drawer and its contents being thrown out. In the case of workshop trolleys, the drawers are usually loaded with relatively heavy objects, so that a drawer that detaches while driving can cause great damage to the interior of the workshop trolley and endanger the driver.

Es ist daher Aufgabe der vorliegenden Erfindung, einen Schrank zu schaffen, dessen Schubladen sich auch bei starken Belastungen, insbesondere im mobilen Einsatz, nicht aus ihrer Zwangsverriegelung lösen.It is therefore an object of the present invention to provide a cabinet whose drawers cannot be released from their positive locking even under heavy loads, particularly in mobile use.

Die Aufgabe wird bei einem Schrank der oben genannten Art erfindungsgemäß durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst. Vorteilhafte Weiterbildungen der Erfindung sind Gegenstand der Unteransprüche.The object is achieved according to the invention in a cabinet of the type mentioned above by the characterizing features of claim 1. Advantageous developments of the invention are the subject of the dependent claims.

Erfindungsgemäß werden zwei Riegel eingesetzt, die gleichzeitig durch den Betätigungsmechanismus betätigbar sind. Jeder Riegel enthält eine Rastnase, die in ein an dem Schrank montierten Riegelschloß eingreift. Beim Schließen der Schublade wird diese zwangsverriegelt, d.h. die Rastnasen gleiten selbsttätig in die Riegelschlösser und bewirken somit eine Verriegelung der Schublade im eingeschobenen Zustand. Die Riegel sind vorzugsweise in der Form von Kniehebeln ausgebildet, die durch den Betätigungsmechanismus, z.B. eine Betätigungsstange, gegensinnig ausgelenkt werden. Die ersten Enden der Riegel sind hierbei zusammengeführt und mit dem Betätigungsmechanismus verbunden, während die zweiten Enden der Kniehebel die Rastnase aufweisen. Es ergibt sich somit durch die beiden Riegel die geometrische Form eines zur Rückwand der Schublade hin offenen U, wobei an den freien Schenkelenden die Rastnasen angeordnet sind, die über die Rückwand der Schublade hinausragen und in die korrespondierenden Riegelschlösser an der Schrankrückwand eingreifen. Die Riegel sind vorzugsweise durch eine Feder in ihre Schließstellung vorgespannt. Sie sind vorzugsweise identisch ausgebildet, wodurch man mit einem minimalen Aufwand an Formwerkzeugen den Verriegelungsmechanismus herstellen kann. Durch die Elastizität des Riegelmechanismus, z.B. durch die Auswahl eines geeigneten elastischen oder gering verformbaren Materials kann sichergestellt werden, daß beide Riegel des Verriegelungsmechanismus bei stärkerer Belastung gleichmäßig in die Riegelschlösser greifen, die Belastung somit gleichmäßig auf beide Riegel wirkt. Hierdurch können kleine Herstellungstoleranzen eliminiert werden.According to the invention, two bolts are used which can be actuated simultaneously by the actuating mechanism. Every bar contains a locking lug that engages in a bolt lock mounted on the cabinet. When the drawer is closed, it is positively locked, ie the locking lugs slide automatically into the bolt locks and thus cause the drawer to be locked when inserted. The bolts are preferably designed in the form of toggle levers which are deflected in opposite directions by the actuating mechanism, for example an actuating rod. The first ends of the latches are brought together and connected to the actuating mechanism, while the second ends of the toggle levers have the locking lug. The two latches thus result in the geometric shape of a U open towards the rear wall of the drawer, the latching lugs being arranged on the free leg ends, which protrude beyond the rear wall of the drawer and engage in the corresponding latch locks on the rear wall of the cabinet. The bolts are preferably biased into their closed position by a spring. They are preferably of identical design, as a result of which the locking mechanism can be produced with a minimal outlay on molding tools. The elasticity of the locking mechanism, for example through the selection of a suitable elastic or slightly deformable material, can ensure that both bolts of the locking mechanism engage evenly in the bolt locks when subjected to greater loads, so that the load acts equally on both bolts. As a result, small manufacturing tolerances can be eliminated.

Vorzugsweise sind die Schubladen mit dem Doppelriegel für schwere Lasten vorgesehen. Es können auch Schubladen für die Aufnahme geringerer Lasten mit einem Einfachriegel vorgesehen sein, wobei dieser vorzugsweise an der Stelle eines der beiden Doppelriegel angeordnet ist. Hierdurch lassen sich Schubladen mit Ein- und Zweiriegelsystem gegeneinander austauschen. Wenn einer der Riegel des erfindungsgemäßen Doppelriegelsystems an der gleichen Stelle wie der Riegel eines bislang bekannten Einriegelsystems angeordnet ist, d.h. der Ort, die Bewegungsrichtung und Form der Rastnase identisch sind, dann läßt sich eine Kompatibilität der Schubladen mit Zweiriegelsystem zu den bereits bestehenden Systemen erreichen. Dies ist besonders von Vorteil, wenn neben den neuen Doppelriegelsystemen noch die herkömmlichen Einriegelsysteme benutzt werden.The drawers are preferably provided with the double latch for heavy loads. Drawers can also be provided with a single latch for receiving lower loads, which is preferably arranged in the place of one of the two double latches. This means that drawers with one and two-bolt systems can be exchanged for one another. If one of the latches of the double latch system according to the invention is arranged at the same location as the latch of a previously known latch system, ie the location, the direction of movement and the shape of the latch are identical, then the drawers can already be compatible with the two latch system reach existing systems. This is particularly advantageous if, in addition to the new double locking systems, the conventional locking systems are used.

In einer kostengünstig herzustellenden Ausbildungsform der Erfindung ist jeder Riegel oder sind beide Riegel mittels einer Riegelplatte an der Schublade befestigt. Die Riegelplatte kann als Stanzblechteil hergestellt werden, das eine hochgebogene Kante aufweist, die eine korrespondierende Perforierung des Riegels durchsetzt und somit das Schwenklager des Riegels bildet. In diesem Fall braucht kein separates, aufwendigeres Stiftgleitlager für den Riegel vorgesehen werden. Um die mechanische Stabilität der Verriegelung in diesem Fall zu erhöhen, hat die Riegelplatte an ihrem der Schubladenrückwand zugewandten Ende eine parallel zu dieser verlaufende Kante, gegen die eine Schulter des Riegels in Schließstellung anliegt. Die Belastung des Riegels liegt in diesem Fall nicht allein auf der hochgebogenen Lagerkante der Riegelplatte, sondern auch auf der parallel zur Rückwand der Schublade hochgebogenen Kante, gegen die die Schulter des Riegels in Schließstellung anliegt. Die Schulter begrenzt einen breiteren oder dickeren Abschnitt des Riegels innerhalb der Schublade gegen einen schmaleren oder dünneren Bereich des Riegels, der durch die Rückwand in Richtung auf das Riegelschloß ragt. Die Schulter muß nicht unbedingt gegen eine hochgebogene Kante der Riegelplatte anliegen, sondern kann auch direkt an der Rückwand der Schublade anliegen.In an embodiment of the invention that is inexpensive to produce, each latch or both latches are attached to the drawer by means of a latch plate. The locking plate can be produced as a stamped sheet metal part which has a raised edge which penetrates a corresponding perforation of the locking bar and thus forms the pivot bearing of the locking bar. In this case, no separate, more complex pin slide bearing needs to be provided for the bolt. In order to increase the mechanical stability of the lock in this case, the locking plate has at its end facing the drawer rear wall an edge running parallel to this, against which a shoulder of the locking bar rests in the closed position. In this case, the load on the bolt lies not only on the raised bearing edge of the locking plate, but also on the edge that is bent up parallel to the rear wall of the drawer, against which the shoulder of the bolt lies in the closed position. The shoulder defines a wider or thicker portion of the bolt within the drawer against a narrower or thinner portion of the bolt that projects through the back wall toward the bolt lock. The shoulder does not necessarily have to lie against a raised edge of the locking plate, but can also lie directly against the rear wall of the drawer.

In einer konstruktionstechnisch sehr einfachen Ausführungsform der Erfindung hat die hochgebogene Lagerkante der Riegelplatte eine Durchbohrung oder Auskehlung, die von einer Stab- oder Blattfeder durchsetzt wird, nachdem der Riegel auf die Riegelplatte aufgesetzt worden ist. Die Blattfeder liegt neben dieser Auskehlung oder Perforierung an zwei Widerlagern an, die zum einen an der Riegelplatte und zum anderen am Riegel vorgesehen sind. Durch diese Stab- oder Blattfeder wird der Riegel in seine Schließstellung vorgespannt und gleichzeitig an der Riegelgelplatte fixiert. So kann der Verriegelungsmechanismus mit einer minimalen Anzahl Anteilen realisiert werden.In a constructionally very simple embodiment of the invention, the raised bearing edge of the locking plate has a through hole or groove which is penetrated by a bar or leaf spring after the locking bar has been placed on the locking plate. The leaf spring is adjacent to this groove or perforation on two abutments, which are provided on the one hand on the locking plate and on the other on the bolt. This bar or leaf spring prestresses the bolt into its closed position and at the same time on the bolt gel plate fixed. In this way, the locking mechanism can be implemented with a minimal number of shares.

Die Riegelschlösser des Schranks sind vorzugsweise als vertikal verlaufende U-Profile vorgesehen, die hinter den Schubladenrückwänden angeordnet sind und fest mit der Rückwand oder einer entsprechenden Tragstruktur des Schrankes verbunden sind. Die seitlichen Schenkel der U-Profile sind perforiert und diese Perforierungen werden von den Rastnasen der Riegel durchsetzt. Ein derartiges Riegelschloß ist sehr stabil, da es mit beiden Schenkeln z.B. durch Punktschweißen oder Schweißen fest mit der Schrankkonstruktion verbunden werden kann.The bolt locks of the cabinet are preferably provided as vertical U-profiles, which are arranged behind the rear wall of the drawer and are firmly connected to the rear wall or a corresponding supporting structure of the cabinet. The side legs of the U-profiles are perforated and these perforations are penetrated by the latches of the bolts. A bolt lock of this type is very stable, since it can be used with both legs e.g. can be firmly connected to the cabinet construction by spot welding or welding.

Der Betätigungsmechanismus für die Riegel ist vorzugsweise durch eine axial bewegliche Stange gebildet, deren umgebogenes oder abgekröpftes hinteres Ende in Perforierungen am ersten Ende beider Riegel eingreift, wohingegen das vordere Ende der Betätigungsstange an die Schubladenfront geführt ist und dort eine Betätigungsfläche, z.B. einen Druckknopf, aufweist.The actuating mechanism for the latches is preferably formed by an axially movable rod, the bent or bent rear end of which engages in perforations at the first end of both latches, whereas the front end of the actuating rod is guided to the drawer front and there is an actuating surface, e.g. has a push button.

Der abgebildete Verriegelungsmechanismus 10 ist unter der Bodenplatte 12 einer Schublade angebracht. Der Verriegelungsmechanismus 10 umfaßt eine Betätigungsstange 14, die mittels Führungsteilen 16 an der Unterseite 12 der Schublade geführt ist. Das hintere Ende der Betätigungsstange 14 ist in Richtung auf den Schubladenboden 12 abgekröpft oder abgebogen und greift in eine Perforierung 18, die an den ersten Enden zweier Riegel 20 angeordnet sind. Die Riegel sind in der Art eines L-förmigen Kniehebels ausgebildet und werden mittels Riegelplatten 22, 24 an dem Schubladenboden 12 gehalten. Die Riegelplatten 22, 24 sind Stanzblechteile, die mit dem Schubladenboden durch irgendeine herkömmliche Verbindungstechnik, wie Schweißen, Punktschweißen, Verformen etc. verbunden sind. Beide Riegel 20 sind identisch ausgebildet und haben im Bereich ihres Knies eine Perforierung 26, die von einer hochstehenden Lagerkante 28 der Riegelplatten 22, 24 durchsetzt wird. Lagerkante 28 und Perforierung 26 bilden das Schwenklager der Riegel 20 auf den Riegelplatten 22, 24. Im Bereich ihrer Verbindung mit der Betätigungsstange 14 sind beide Riegel gekröpft, so daß deren Enden in etwa parallel übereinander liegen, wodurch die dort angeordneten Perforierungen 18 zur Befestigung der Betätigungsstange 14 konzentrisch angeordnet sind. Im Bereich der Abkröpfung der Riegel sind Löcher 30 ausgestanzt, die als Widerlager für Federn 32 dienen, die eine Perforierung der Lagerkanten 28 durchsetzen und an zweiten Widerlagern 34 der Riegelplatten abgestützt sind. Durch diese Konstruktion werden zum einen die Riegel 20 in ihre Schließposition vorgespannt und zum anderen zwischen den Riegelplatten 22, 24 und den Federn 32 festgelegt. An den rückwärtigen Enden der Riegel 20 sind Rastnasen 36 angeordnet, die in Riegelschlösser 38 eingreifen, die als U-Profile ausgebildet und mit der Schrankrückwand 40 verbunden sind. Die U-Profile 38 weisen in ihren seitlichen Schenkeln Perforierungen auf, in die die Rastnasen 36 in der dargestellten Schließstellung der Riegel eingreifen.The locking mechanism 10 shown is attached under the base plate 12 of a drawer. The locking mechanism 10 comprises an actuating rod 14 which is guided by means of guide parts 16 on the underside 12 of the drawer. The rear end of the actuating rod 14 is bent or bent in the direction of the drawer bottom 12 and engages in a perforation 18, which at the first ends of two bars 20 are arranged. The latches are designed in the manner of an L-shaped toggle lever and are held on the drawer base 12 by means of latch plates 22, 24. The locking plates 22, 24 are stamped sheet metal parts which are connected to the drawer bottom by any conventional connection technique, such as welding, spot welding, deforming, etc. Both bars 20 are of identical design and have a perforation 26 in the area of their knee, which is penetrated by a raised bearing edge 28 of the locking plates 22, 24. Bearing edge 28 and perforation 26 form the pivot bearing of the latch 20 on the latch plates 22, 24. In the area of their connection to the actuating rod 14, both latches are cranked, so that their ends lie approximately parallel one above the other, as a result of which the perforations 18 arranged there for fastening the Actuating rod 14 are arranged concentrically. Holes 30 are punched out in the area of the cranking of the bolts, which serve as abutments for springs 32, which perforate the bearing edges 28 and are supported on second abutments 34 of the bolt plates. With this construction, on the one hand the bolts 20 are prestressed into their closed position and on the other hand they are fixed between the bolt plates 22, 24 and the springs 32. At the rear ends of the latches 20 latching lugs 36 are arranged which engage in latch locks 38 which are designed as U-profiles and are connected to the cabinet rear wall 40. The U-profiles 38 have perforations in their lateral legs, into which the locking lugs 36 engage in the locking position shown in the latch.

Die Riegelplatten weisen ferner eine parallel zur Schubladenrückwand 42 verlaufende, d.h. von der Riegelplatte 22, 24 hochgebogene Kante 44 auf, gegen die eine Schulter 46 der Riegel 20 in der dargestellten Schließstellung anliegt. Die Schulter 46 stellt den Übergang zwischen einem breiteren innerhalb der Schublade befindlichen Riegelteil und einem durch die Rückwand 42 nach außen ragenden schmaleren Riegelteil dar. In der dargestellten Schließstellung ist die Schublade somit bei einer die Schublade nach außen ziehenden Belastung abgestützt durch die in den Riegelschlössern 28 befindlichen Rastnasen 36 der Riegel in den Riegelschlössern 28 befindlichen Rastnasen 36 der Riegel 20 und durch die an den Kanten 44 abgestützten Schultern 46 der Riegel 20 und die hochgebogenen Lagerkanten 28. Die Schultern 46 der Riegel 20 können auch direkt an der Rückwand abgestützt sein, was jedoch aufgrund der Toleranzen beim Einbau der Riegelplatte in die Schublade ungünstiger ist. Der gesamte, auf dem Verriegelungsmechanismus 10 lastende Zug wird somit nicht allein durch das Schwenklager 26, 28 der Riegel 20, sondern zusätzlich durch die Schultern 46 der Riegel 20 abgefangen. Diese Konstruktion ist daher insbesondere in der Lage, schwer befüllte Schubladen in mobilen, d.h. z.B. in Fahrzeugen befindlichen Schränken gegen ein Herausgleiten abzusichern. Dies ist vor allem dann wichtig, wenn die Schublade mit ihrer Öffnungs- und Schließrichtung in Fahrzeugrichtung eingebaut ist. Dann wirken die beim Abbremsen und Beschleunigen des Fahrzeugs auftretenden Trägheitskräfte der Schublade direkt auf den Verschließmechanismus. Die Betätigungsstange 14 hat an ihrer der Schubladenfront 48 zugewandten Seite eine Betätigungsfläche 50, durch die die Zwangsverriegelung der Schublade gelöst werden kann.The locking plates also have an edge 44 which runs parallel to the rear wall 42 of the drawer, ie which is bent up by the locking plate 22, 24, against which a shoulder 46 of the locking bar 20 rests in the closed position shown. The shoulder 46 represents the transition between a wider bolt part located inside the drawer and a narrower bolt part protruding outward through the rear wall 42. In the closed position shown, the drawer is thus supported by a load pulling the drawer outwards by the loads in the bolt locks 28 located latches 36 of the bolt located in the bolt locks 28 locking lugs 36 of the bolt 20 and by the shoulders 46 supported on the edges 46 of the bolt 20 and the raised bearing edges 28. The shoulders 46 of the bolt 20 can also be supported directly on the rear wall, but this is due to the tolerances in Installation of the locking plate in the drawer is less favorable. The entire train on the locking mechanism 10 is thus not only intercepted by the pivot bearing 26, 28 of the bolt 20, but also by the shoulders 46 of the bolt 20. This construction is therefore in particular able to secure heavily filled drawers in mobile cabinets, that is to say for example in vehicles, against sliding out. This is particularly important if the drawer is installed with its opening and closing direction in the vehicle direction. Then the inertial forces of the drawer that occur when braking and accelerating the vehicle act directly on the locking mechanism. The actuating rod 14 has an actuating surface 50 on its side facing the drawer front 48, through which the forced locking of the drawer can be released.

Fig. 3 zeigt in sehr eindrucksvoller Weise, wie flach die andererseits sehr stabile und wirkungsvolle Zwangsverriegelung konstruiert werden kann. Sehr gut zu sehen sind in dieser Figur die hochgebogenen Kanten 44, an denen sich die Schulter 46 der Riegel 20 in Schließstellung abstützen.Fig. 3 shows very impressively how flat the otherwise very stable and effective positive lock can be constructed. The bent edges 44 on which the shoulder 46 of the latch 20 are supported in the closed position can be seen very well in this figure.

Beim Öffnen werden die ersten Enden der Riegel 20 in Richtung auf die Schubladenrückwand bewegt, wodurch beide Riegel 20 eine Drehung um das Schwenklager 26,28 vollführen. Dabei treten die Rastnasen 36 außer Eingriff mit den Riegelschlössern 38, die an der Schrankrückwand 40 angeordnet sind.When opened, the first ends of the latches 20 are moved in the direction of the drawer rear wall, as a result of which both latches 20 rotate about the pivot bearing 26, 28. The locking lugs 36 disengage from the bolt locks 38 which are arranged on the rear wall 40 of the cabinet.

Eine sehr gute Sicherung der Schublade gegen eine Zugkräfte wird durch die Ausbildung der oben beschriebenen Schulter erzielt, welche sich gegen ein Teil der Schublade oder der Riegelplatte abstützt und damit die auf den Riegel wirkenden Zugkräfte aufnimmt. Dieser Vorteil wird bereits erzielt, wenn der Verriegelungsmechanismus nur einen Riegel aufweist.A very good securing of the drawer against tensile forces is achieved by the formation of the shoulder described above, which is supported against part of the drawer or the locking plate and thus absorbs the tensile forces acting on the bolt. This advantage is already achieved when the locking mechanism has only one latch.
