Description

Die Erfindung betrifft einen Werkzeugkoffer mit den Merkmalen nach dem Oberbegriff des Anspruchs 1.The invention relates to a tool case having the features according to the preamble of claim 1.

Für die Lagerhaltung und den Transport von tragbaren Arbeitsgeräten wie handgeführte Elektrowerkzeuge, Bohrmaschinen oder dergl. sowie für schwere Werkzeuge im allgemeinen sind eine Vielzahl von Werkzeugkoffern bekannt, die einer Reihe von teils widersprüchlichen Anforderungen gerecht werden müssen. Beispielsweise müssen bei der Lagerhaltung von Neugeräten die sie umschließenden Werkzeugkoffer gut stapelbar sein, wobei der eingenommene Lagerraum möglichst gering sein soll. Daraus folgen Anforderungen bezüglich einer möglichst großen maximalen Stapelhöhe in Verbindung mit einer kompakten Bauform. Wegen der daraus resultierenden hohen mechanischen Belastungen der jeweils unten im Stapel liegenden Werkzeugkoffer müssen diese entsprechend kräftig ausgelegt sein. Gleichzeitig ist beispielsweise für eine leichte Handhabung an einer Baustelle ein geringes Eigengewicht des Werkzeugkoffers erwünscht..For the storage and transport of portable equipment such as hand-held power tools, drills or the like. As well as heavy tools in general, a variety of tool cases are known to meet a number of partly conflicting requirements. For example, when storing new appliances, the tool cases surrounding them must be easy to stack, with the storage space taken to be as small as possible. This results in requirements for the largest possible maximum stack height in conjunction with a compact design. Because of the resulting high mechanical loads of each lying below in the stack tool box they must be designed accordingly strong. At the same time, for example, a low weight of the tool case is desired for easy handling on a construction site.

Aus der EP 0 555 533 ist ein stapelbarer Koffer für transportable Werkzeugmaschinen bekannt, der ein kasten- oder schalenförmiges Unterteil und einen Deckel aufweist. Eine Stapelung mehrerer Koffer ist derart möglich, daß jeweils das Unterteil eines oberen Koffers auf dem Deckel des unmittelbar darunter angeordneten Koffers aufsitzt. Der Deckel des jeweils unteren Koffers ist zwischen dem Unterteil dieses unteren Koffers und dem Unterteil des unmittelbar darüber angeordneten oberen Koffers festgelegt. Im gestapelten Zustand muß also ein derartiger Deckel das Gewicht eines oder mehrerer darüber gestapelter Koffer mit deren Inhalt tragen. Der Deckel wird dadurch erheblich belastet, was zu Schädigungen des Deckels selbst oder der ihn haltenden Scharniere bzw. Verschlüsse führen kann. Es sind Verbindungsmittel vorgesehen, die unter Bildung einer aus mehreren Koffern bestehenden, zusammenhängenden Transporteinheit eine lösbare Verbindung zwischen den Unterteilen zweier jeweils unmittelbar aufeinander sitzender Koffer eines Kofferstapels ermöglichen. Dadurch soll erreicht werden, daß ein Kofferstapel am obersten Koffer angehoben werden kann, wobei die jeweils unteren Koffer mit den Verbindungsmitteln daruntergehängt sind. Für eine innige, ein gegenseitiges Verrutschen der Koffer untereinander hemmende Verbindung ist eine gewisse Vorspannkraft der Verbindungsmittel erforderlich.From the EP 0 555 533 is a stackable case known for portable machine tools, the one box-shaped or cup-shaped lower part and having a lid. A stacking of several suitcases is possible in such a way that in each case the lower part of an upper suitcase is seated on the lid of the suitcase immediately below. The lid of the respective lower case is defined between the lower part of this lower case and the lower part of the upper case arranged immediately above. In the stacked state, therefore, such a cover must carry the weight of one or more stacked suitcases with their contents. The lid is thereby considerably burdened, which can lead to damage to the lid itself or the hinges or closures holding it. There are provided connecting means, which allow a releasable connection between the lower parts of each two directly juxtaposed suitcase of a suitcase stack forming a plurality of suitcases, contiguous transport unit. This is intended to ensure that a stack of cases can be lifted at the top of the case, the lower case are suspended with the connecting means underneath. For an intimate, a mutual slippage of the suitcase with each other inhibiting connection a certain biasing force of the connecting means is required.

Ein Kuffer gemäß den Oberbegriff des Anspruchs 1 ist aus US 5225300 A bekannt.A buffer according to the preamble of claim 1 is made US 5225300 A known.

Der Erfindung liegt die Aufgabe zugrunde, einen gattungsgemäßen Werkzeugkoffer derart weiterzubilden, daß seine Stapelbarkeit verbessert und seine Belastung im gestapelten Zustand verringert ist.The invention has the object of providing a generic tool case in such a way that its stackability improved and its load is reduced in the stacked state.

Diese Aufgabe wird durch einen Werkzeugkoffer mit den Merkmalen des Anspruchs 1 gelöst.This object is achieved by a tool case having the features of claim 1.

Dazu wird vorgeschlagen, daß am Unterteil eines Werkzeugkoffers in der Hochrichtung sich erstreckende Stapelpfosten vorgesehen sind, zwischen denen eine den Deckel bildende Abdeckung im geschlossenen Zustand liegt. Das Unterteil und die daran angeordneten Stapelpfosten sind derart ausgebildet, daß sich das Unterteil eines aufgestapelten Werkzeugkoffers an den Stapelpfosten des jeweils unteren Werkzeugkoffers abstützt. Dadurch hat der Deckel im gestapelten Zustand keine statische Funktion und kann gemeinsam mit vorhandenen Scharnieren und Verschlüssen entsprechend leicht und einfach ausgeführt sein. Des weiteren ist dadurch die Möglichkeit gegeben, die Abdeckung frei nach den Erfordernissen der abzudeckenden öffnung bzw. des zu transportierenden Werkzeuges auszulegen, ohne dabei die statische Belastung bei einer Stapelbildung berücksichtigen zu müssen. In einer zweckmäßigen Weiterbildung ist ein Schubfach mit einem Gehäuseteil und einer horizontal einschiebbaren Schublade beispielsweise für Zubehörteile vorgesehen. Das Schubfach ist vergleichbar zum Werkzeugkoffer ausgebildet, in dem Stapelpfosten insbesondere in den Seitenwänden die Gewichtskräfte aufnehmen, wodurch die Schublade im wesentlichen kraftfrei ist. Die Schublade kann dadurch nach vorne aus dessen Gehäuseteil herausgezogen werden, ohne die Verbindung zum darüberliegenden Werkzeugkoffer zu lösen. Durch eine insbesondere einstückige Ausformung der Stapelpfosten mit dem Unterteil ist eine durchgängige Kraftübertragung ohne schwächende Verbindungsstellen erzielbar, wodurch hohe Stapel auch mit schweren eingelegten Arbeitsgeräten bildbar sind. Auftretende Stoßbelastungen beispielsweise im Baustellenbetrieb können verbessert aufgenommen werden. Dabei weist die Abdeckung zweckmäßig im gestapelten Zustand der Werkzeugkoffer in der Hochrichtung einen Abstand zum darüber liegenden Unterteil auf. Dadurch ist sichergestellt, daß auch im verschmutzten Zustand der Abdeckung, des Unterteiles oder beider Teile eine Kraftübertragung im gestapelten Zustand von einem Unterteil auf die darunterliegende Abdeckung unterbleibt. Durch den Abstand ist auch eine mindestens geringfügige öffnung der Abdeckung im gestapelten Zustand möglich, wodurch beispielsweise kontrolliert werden kann, ob in einem fraglichen Koffer innerhalb eines Stapels sich ein Werkzeug befindet.For this purpose, it is proposed that stacking posts extending in the vertical direction are provided on the lower part of a tool box, between which a cover forming the cover lies in the closed state. The lower part and the stacking posts arranged thereon are designed such that the lower part of a stacked tool box is supported on the stacking posts of the respectively lower tool box. As a result, the lid in the stacked state has no static function and can be carried out together with existing hinges and fasteners accordingly easy and simple. Furthermore, this gives the possibility to design the cover freely according to the requirements of the opening to be covered or the tool to be transported, without having to take into account the static load in a stack formation. In an expedient development, a drawer with a housing part and a horizontally insertable drawer is provided for example for accessories. The drawer is formed similar to the tool box, take in the stacking post, in particular in the side walls, the weight forces, whereby the drawer is substantially free of force. The drawer can be pulled out of the front of the housing part, without loosening the connection to the overlying tool box. By a particular one-piece shape of the Stacking post with the lower part is a continuous power transmission without weakening joints achieved, whereby high stack can be formed even with heavy work implements. Occurring shock loads, for example, in construction site operation can be improved recorded. In this case, the cover expediently in the stacked state of the tool case in the vertical direction at a distance to the lower part lying over. This ensures that even in the dirty state of the cover, the lower part or both parts of a power transmission in the stacked state of a lower part on the underlying cover is omitted. Due to the distance, an at least slight opening of the cover in the stacked state is possible, which can be controlled, for example, whether in a case in question within a stack is a tool.

Zwei gegenüberliegende Seitenwände des Unterteils sind seitlich an der Abdeckung vorbei hochgezogen und bilden dabei die Stützpfosten. Der konstruktive Aufwand für diese Ausbildung ist gering. Im gestapelten Zustand werden die Seitenwände innerhalb ihrer Wandebene belastet, wodurch eine hohe Tragfähigkeit auch bei einer dünnwandigen und entsprechend leichten Bauweise gegeben ist. Die zwischen den Seitenwänden liegende Abdeckung kann großflächig gestaltet sein, wodurch ein ungehinderter Zugriff auf den Inhalt des Werkzeugkoffers ermöglicht ist. Dabei ist die Abdeckung an einer zwischen den Seitenwänden liegenden Rückwand des Unterteils mit Scharnieren schwenkbar befestigt und an einer der Rückwand gegenüber liegenden Vorderwand des Unterteils mit einem Verschluß festlegbar. Durch die Anbindung mit Scharnieren kann die Abdeckung nicht verloren gehen. In Verbindung mit den seitlich hochgezogenen Seitenwänden ist ein freies Schwenken der Abdeckung möglich, was den Zugriff auf den Innenraum des Werkzeugkoffers erleichtert. Zweckmäßig sind dabei zwei seitlich von der Mitte der Vorderwand versetzt angeordnete Verschlüsse vorgesehen. Dadurch ist einerseits ein einfaches öffnen bzw. Verschließen der Abdeckung ermöglicht, wobei je ein Verschluß durch je eine Hand einer Bedienperson gleichzeitig betätigt werden kann. Gleichzeitig ist in Verbindung mit den Scharnieren eine gut verteilte Kraftübertragung zwischen der Abdeckung und dem Unterteil ermöglicht, was punktuelle Kraftspitzen an der Abdeckung vermeidet und eine entsprechend leichte Konstruktion ermöglicht. Die Verschlüsse sind dabei vorteilhaft bezüglich der Außenkontur des Werkzeugkoffers im geschlossenen Zustand versenkt, was ein unbeabsichtigtes Anstoßen oder Abreißen vermeidet und zur Verringerung des notwendigen Lagerraumes insbesondere im gestapelten Zustand beiträgt. Die Verschlüsse sind vorteilhaft derart ausgebildet, daß sie beim Schließen der Abdeckung selbständig einschnappen, wodurch die Abdeckung sich dann nicht mehr von selbst öffnen kann. Dies steigert die Sicherheit gegen Herausfallen des Inhalts. Zum vollständigen Verschließen werden die Verschlüsse abschließend manuell in ihre Verriegelungsposition gedrückt.Two opposite side walls of the lower part are pulled laterally past the cover and thereby form the support posts. The design effort for this training is low. In the stacked state, the side walls are loaded within their wall plane, whereby a high load capacity is given even with a thin-walled and correspondingly lightweight design. The cover lying between the side walls can be designed over a large area, whereby unhindered access to the contents of the tool case is possible. The cover is at one between the Side walls lying rear wall of the lower part with hinges pivotally mounted and secured to one of the rear wall opposite the front wall of the lower part with a closure. Due to the connection with hinges, the cover can not be lost. In conjunction with the side raised side walls a free pivoting of the cover is possible, which facilitates access to the interior of the tool box. Appropriately, two laterally offset from the center of the front wall arranged closures are provided. As a result, on the one hand, a simple opening or closing of the cover allows each one closure can be actuated by one hand of an operator at a time. At the same time in conjunction with the hinges a well-distributed power transmission between the cover and the lower part allows, which avoids selective force peaks on the cover and allows a correspondingly lightweight construction. The closures are advantageously recessed with respect to the outer contour of the tool case in the closed state, which avoids unintentional abutment or tearing and contributes to reducing the necessary storage space, especially in the stacked state. The closures are advantageously designed so that they snap independently when closing the cover, so that the cover then can not open by itself. This increases the security against falling out of the content. For complete closure, the closures are final manually pressed into its locking position.

Die Stapelbarkeit ist weiter dadurch verbessert, daß Mittel gegen Verrutschen übereinander gestapelter Werkzeugkoffer quer zur Hochrichtung vorgesehen sind. Diese sind insbesondere als formschlüssig ineinandergreifende Vorsprünge und Führungsvertiefungen ausgebildet und zweckmäßig mit seitlichen Abschrägungen versehen. Dadurch ist eine präzise ausgerichtete Stapelbildung mit entsprechend geringem Lagerraum ermöglicht. Bei einem Transport beispielsweise in einem Fahrzeug zur Baustelle ist ein Verrutschen übereinander gestapelter Werkzeugkoffer gegeneinander vermieden. Durch die Abschrägungen ist das Bilden eines Stapels vereinfacht, da ein oberer Werkzeugkoffer nur ungenau auf einen unteren aufgelegt werden muß, wobei die seitlichen Abschrägungen ein Hineinrutschen der Vorsprünge in die entsprechenden Führungsvertiefungen begünstigt. Insbesondere sind die Vorsprünge am Unterteil angeordnet und derart ausgebildet, daß sie bezüglich dessen Boden entgegen der Hochrichtung hervorstehen. Neben ihrer Funktion als Stapelhilfe können die Vorsprünge bei einem einzelnen abzustellenden Werkzeugkoffer auch die Funktion von Stellfüßen ausfüllen.The stackability is further improved by the fact that means are provided against slipping stacked tool box transverse to the vertical direction. These are designed in particular as form-fitting interlocking projections and guide recesses and expediently provided with lateral bevels. This allows a precisely aligned stacking with correspondingly small storage space. In a transport, for example, in a vehicle to the site slipping stacked tool box is avoided against each other. The chamfers simplify the formation of a stack, since an upper tool box need only be placed inaccurately on a lower one, with the lateral chamfers favoring the projections to slide into the corresponding guide slots. In particular, the projections are arranged on the lower part and designed so that they protrude with respect to the bottom opposite to the vertical direction. In addition to their function as a stacking aid, the projections can also fill the function of feet in a single abzustellenden tool box.

In einer vorteilhaften Ausbildung sind in der Abdeckung seitlich an die beiden Seitenwände angrenzend je eine Führungsvertiefung vorgesehen und derart ausgebildet, daß dort eingreifende Vorsprünge eines darüberliegenden Unterteils sich innenseitig an den Seitenwänden abstützen können. Dadurch kann für eine seitliche Führung auf die Anordnung von Führungsvertiefungen auf der Oberseite der Seitenwände verzichtet werden, so daß diese sehr schmal bzw. der Deckel sehr breit ausgelegt sein kann. Die Führungsvertiefungen sind zweckmäßig jeweils im Bereich der Rückwand und der Vorderwand vorgesehen, wobei die Führungsvertiefungen im Bereich der Vorderwand von denen im Bereich der Rückwand durch Anschlagflächen getrennt sind. Dabei sind entsprechend geformte Vorsprünge mit entsprechenden Anschlagflächen vorgesehen, die in diese Führungsvertiefungen beim Aufeinanderstapeln eingreifen. Die aneinander anliegenden Anschlagflächen dienen dabei als Sicherung gegen Verrutschen in einer Richtung von der Vorderwand zur Rückwand bzw. umgekehrt. Dabei kann es zweckmäßig sein, die jeweiligen Führungsvertiefungen in Richtung der angrenzenden Rückwand bzw. der angrenzenden Vorderwand offen zu gestalten. Dadurch ist es möglich, einen Werkzeugkoffer beispielsweise schräg von vorne auf einen unteren Werkzeugkoffer aufzusetzen und nach hinten in Richtung der Rückwand zu schieben. Dabei können die Vorsprünge im Bereich der Vorderwand in die entsprechenden geöffneten Führungsvertiefungen hineingleiten, bis die hinteren Vorsprünge im Bereich der Rückwand über ihren entsprechenden Führungsvertiefungen liegen und insbesondere durch die Abschrägungen geführt in die Führungsvertiefungen hineingleiten.In an advantageous embodiment, a guide recess are provided laterally adjacent to the two side walls in the cover and designed such that there engaging projections of an overlying Bottom parts can be supported on the inside of the side walls. As a result, it is possible to dispense with the arrangement of guide depressions on the upper side of the side walls for a lateral guidance so that they can be designed to be very narrow or the cover very wide. The guide recesses are expediently provided in each case in the region of the rear wall and the front wall, wherein the guide recesses in the region of the front wall are separated from those in the region of the rear wall by abutment surfaces. In this case, correspondingly shaped projections are provided with corresponding stop surfaces, which engage in these guide recesses when stacking. The adjoining abutment surfaces serve as a safeguard against slipping in one direction from the front wall to the rear wall or vice versa. It may be appropriate to make the respective guide depressions in the direction of the adjacent rear wall or the adjacent front wall open. This makes it possible, for example, set up a tool case obliquely from the front on a lower tool case and to push backwards in the direction of the rear wall. The projections in the region of the front wall can slide into the corresponding open guide recesses until the rear projections lie above their corresponding guide recesses in the area of the rear wall and, in particular, slide into the guide recesses through the bevels.

Als weiteres Mittel zur Sicherung gegen Verrutschen insbesondere in der parallel zu den Seitenwänden verlaufenden Richtung können die Seitenwände auf ihrer in der Hochrichtung weisenden Oberseite eine Ausnehmung und auf ihrer gegenüberliegenden Unterseite eine entsprechende Erhöhung aufweisen. Beim Übereinanderstapeln greifen die unten liegenden Erhöhungen eines oberen Werkzeugkoffers in die entsprechenden obenliegenden Ausnehmungen in den Seitenwänden eines unteren Werkzeugkoffers und bilden dabei einen Formschluß. Insbesondere sind dabei die Ausnehmungen und Erhöhungen durch beim Stapeln aneinanderlegbare, schräg verlaufende Druckflächen begrenzt, die in einfacher Weise einen präzisen Formschluß derart ermöglichen, daß sowohl Kräfte in vertikaler wie auch horizontaler Richtung aufgenommen werden können. Dadurch ist auch ein präzise definierter Ort der Krafteinleitung gegeben, der konstruktiv örtlich entsprechend verstärkt sein kann, während die übrigen Bereiche der Seitenwände einfach und leicht gehalten sein können. Dabei kann es zweckmäßig sein, die Oberseite der Seitenwände konvex und deren Unterseite konkav gekrümmt auszugestalten. Durch die konkave Krümmung der Unterseite ist vermieden, daß ein einzelner, auf einer ebenen Fläche abgestellter Werkzeugkoffer mit seiner unten liegenden Erhöhung aufliegt, so daß eine kippsichere Ablage des Werkzeugkoffers ermöglicht ist. Beim Bilden eines Stapels von Werkzeugkoffern liegen die konkav gekrümmten Unterseiten der Seitenwände jeweils flächig an den entsprechenden konvex gekrümmten Oberseiten an und erlauben eine flächige, tragfähige Kraftübertragung in den Seitenwänden ohne Belastung der Abdeckung. Durch die unterschiedlich gerichtete Krümmung der Ober- und Unterseite ist für den Benutzer die Oberseite mit der Abdeckung auch beim Fehlen weiterer Markierungen mit einem Blick erkennbar, so daß eine Ablage des Werkzeugkoffers mit seiner Oberseite nach unten gekehrt und den damit bekannten, beim öffnen einhergehenden Folgen vermieden ist.As a further means for securing against slipping, in particular in the direction parallel to the side walls extending direction, the side walls may have a recess on its upper side facing in the vertical direction and a corresponding elevation on its opposite underside. When stacking, the lower elevations of an upper tool case engage in the corresponding upper recesses in the side walls of a lower tool case and thereby form a positive engagement. In particular, the recesses and elevations are limited by stackable, oblique pressure surfaces that allow in a simple manner a precise positive engagement so that both forces can be absorbed in the vertical and horizontal direction. As a result, a precisely defined location of the introduction of force is given, which can be structurally locally reinforced accordingly, while the remaining areas of the side walls can be kept simple and light. It may be expedient to make the top of the side walls convex and the bottom concave curved. Due to the concave curvature of the bottom is avoided that a single, parked on a flat surface tool case rests with its lower elevation, so that a tip-safe storage of the tool case is possible. When forming a stack of tool cases, the concavely curved undersides of the side walls abut each other flat against the corresponding convexly curved upper sides and allow a planar, viable power transmission in the side walls without loading the cover. Due to the differently directed curvature of the top and bottom of the user can see the top with the cover even in the absence of other marks at a glance, so that a filing of the tool box swept with its top down and the known, the opening-related consequences is avoided.

In einer vorteilhaften Ausbildung sind Mittel zur insbesondere lösbaren formschlüssigen Verbindung in der Hochrichtung von übereinander gestapelten Werkzeugkoffern vorgesehen, wodurch das Tragen mehrerer gestapelter Werkzeugkoffer an einem Handgriff ermöglicht ist. In Verbindung mit den oben beschriebenen Mitteln gegen seitliches Verrutschen ist dadurch eine formschlüssige Verbindung einzelner Werkzeugkoffer untereinander in allen drei räumlichen Achsen erzielbar, so daß ein derart gebildeter Stapel auch seitlich gekippt und anschließend beispielsweise an einem an der Vorderseite angebrachten Handgriff angehoben und getragen werden kann. Die entsprechenden Verbindungsmittel sind zweckmäßig an den Stützpfosten und insbesondere an den die Stützpfosten bildenden Seitenwänden vorgesehen. Bei einer derartigen Anordnung kann wegen bereits vorhandenen hohen Tragfähigkeit der Seitenwände auf zusätzliche Verstärkungen verzichtet werden, so daß die übrigen Bereiche des Werkzeugkoffers in entsprechender Leichtbauweise gestaltet sein können. In einer zweckmäßigen Ausbildung ist dazu an den beiden Seitenwänden im Bereich ihrer Oberseite und ihrer Unterseite je eine Rippe vorgesehen, wobei eine jeweils oben liegende Rippe eines unteren Werkzeugkoffers gemeinsam mit einer benachbarten unteren Rippe eines aufgestapelten oberen Werkzeugkoffers von einer Klammer umgriffen werden kann. Diese Anordnung aus Klammern und Rippen weist bei einer einfachen konstruktiven Gestaltung und entsprechend geringem Fertigungsaufwand eine hohe Tragfähigkeit auf. Die Klammern sind dabei zweckmäßig schwenkbar an den jeweiligen Seitenwänden festgelegt, so daß diese im gelösten Zustand nicht verloren gehen können. Die Klammern können vorteilhaft als schwenkbare Haltegriffe ausgeführt sein, wodurch ihnen eine Doppelfunktion zukommt: Die Klammern in einem unteren Bereich eines Werkzeugkofferstapels verbinden diese formschlüssig miteinander in der Hochrichtung, während die obersten Klammern seitlich ausgeschwenkt werden können und dabei als Haltegriff zum Anheben oder Tragen des gesamten Stapels dienen können. Durch Anordnung von Verriegelungsvertiefungen, in denen die letztgenannten Mittel zur formschlüssigen Verbindung versenkbar sind, ist der erforderliche Lagerraum gering gehalten. Beispielsweise bei nebeneinander in einem Regal angeordneten Stapeln können einzelne Werkzeugkoffer nach vorne herausgezogen werden, ohne daß die seitlichen Klammern benachbarter Stapel sich ineinander verhaken können.In an advantageous embodiment means for releasable in particular form-locking connection in the vertical direction of stacked tool cases are provided, whereby the carrying a plurality of stacked tool case is made possible on a handle. In conjunction with the above-described means against lateral slippage thereby a positive connection of individual tool case is mutually achievable in all three spatial axes, so that a stack formed in this way can also be tilted laterally and then raised, for example, on a handle attached to the front and worn. The corresponding connection means are expediently provided on the support posts and in particular on the side walls forming the support posts. With such an arrangement can be dispensed with additional reinforcements because of existing high load capacity of the side walls, so that the remaining areas of the tool box can be designed in a corresponding lightweight construction. In an expedient training is on each of the two side walls in the region of its top and bottom a rib provided, wherein a respective upper rib of a lower tool case can be encompassed by a clamp together with an adjacent lower rib of a stacked upper tool box. This arrangement of brackets and ribs has a high structural capacity with a simple structural design and correspondingly low production costs. The brackets are expediently pivotally fixed to the respective side walls, so that they can not be lost in the dissolved state. The brackets can advantageously be designed as swiveling handles, whereby they have a double function: The brackets in a lower portion of a tool case stack connect these form-fitting together in the vertical direction, while the top brackets can be swung laterally and thereby as a handle for lifting or carrying the entire Stack can serve. By arranging locking recesses in which the latter means for positive connection are retractable, the required storage space is kept low. For example, in juxtaposed on a shelf stacks individual tool box can be pulled forward without the lateral brackets of adjacent stacks can get caught in each other.

Als Sicherung gegen einen unbefugten Zugriff auf ein wertvolles, im Werkzeugkoffer gelagertes Gerät ist die Abdeckung zweckmäßig am Unterteil abschließbar festzulegen. In einer einfachen und wirkungsvollen Ausführung ist dazu jeweils in der Vorderwand und im angrenzenden Bereich der Abdeckung je eine Öffnung vorgesehen, durch die beispielsweise ein Vorhängeschloß hindurchgeführt werden kann.As a safeguard against unauthorized access to a valuable, stored in the tool box device cover is expedient set lockable on the lower part. In a simple and effective execution For this purpose, an opening is respectively provided in the front wall and in the adjacent area of the cover, through which, for example, a padlock can be passed.

Zur Erzielung einer hohen Tragfähigkeit bei einem geringen Gewicht und vertretbaren Fertigungskosten ist der Werkzeugkoffer und insbesondere sein Unterteil, die Abdeckung und die Klammern aus Kunststoff hergestellt. Bei einer komplexen geometrischen Ausgestaltung des Werkzeugkoffers ist die Verarbeitung des Kunststoffes auf dem Wege des Spritzgießens zweckmäßig. Für eine hohe Tragfähigkeit in Verbindung mit einer entsprechenden Schlagfähigkeit und guter Verarbeitbarkeit hat sich Polypropylen oder ABS als zweckmäßig herausgestellt.To achieve a high load capacity with a low weight and reasonable manufacturing costs of the tool case and in particular its lower part, the cover and the brackets made of plastic. In a complex geometric design of the tool case, the processing of the plastic by way of injection molding is appropriate. For a high load capacity in conjunction with a corresponding impact resistance and good processability, polypropylene or ABS has proven to be useful.

In Fig. 1 ist ein erfindungsgemäßer Werkzeugkoffer gezeigt, dessen Unterteil 2 eine in einer Hochrichtung 1 weisende öffnung 3 aufweist, die durch eine Abdeckung 4 verschlossen ist. Die Abdeckung 4 ist im Bereich der Rückwand 7 des Unterteils 2 mit in Fig. 5 näher gezeigten Scharnieren 8 schwenkbar festgelegt und im Bereich der der Rückwand 7 gegenüberliegenden Vorderwand 9 mit zwei Verschlüssen 10 im verschlossenen Zustand gehalten. Es kann auch eine Ausbildung zweckmäßig sein, bei der die Abdeckung 4 ohne Scharniere 8 lösbar mit weiteren Verschlüssen 10 oder Schnappverbindungen an der Rückwand 7 und/oder an den Seitenwänden 6 festlegbar ist. Die beiden Seitenwände 6 des Unterteils 2 sind seitlich an der Abdeckung 4 vorbei hochgezogen und bilden Stapelpfosten 5. Es kann auch zweckmäßig sein, separat ausgebildete Stapelpfosten 5 im Bereich der Seitenwände, der Rückwand 7 und/oder der Vorderwand 9 vorzusehen. An der Vorderwand 9 ist ein um eine Achse 33 in Richtung des Pfeils 32 schwenkbarer Tragegriff 31 vorgesehen. Der Tragegriff 31 und die beiden Verschlüsse 10 sind in der gezeigten ruhenden bzw. geschlossenen Position bezüglich der Außenkontur des Werkzeugkoffers versenkt. Die Abdeckung 4 und das Unterteil 2 weisen im Bereich der Vorderwand 9 je eine öffnung 29, 30 auf, durch die ein Vorhängeschloß hindurchführbar ist und wodurch die Abdeckung 4 gegenüber dem Unterteil 2 abgeschlossen werden kann. Es kann auch die Anordnung eines integrierten Zahlenschlosses oder dergl. zweckmäßig sein. Im Bereich des Unterteils 2, der Abdeckung 4 und der Seitenwände 6 sind Mittel 12 gegen Verrutschen übereinander gestapelter Werkzeugkoffer quer zur Hochrichtung 1 vorgesehen. Die Mittel 12 gegen Verrutschen sind weiter unten näher beschrieben.In Fig. 1 an inventive tool case is shown, the lower part 2 has a facing in a vertical direction 1 opening 3, which is closed by a cover 4. The cover 4 is in the region of the rear wall 7 of the lower part 2 with in Fig. 5 Hinges 8 shown pivotally fixed and held in the region of the back wall 7 opposite front wall 9 with two closures 10 in the closed state. It may also be useful training in which the cover 4 without hinges 8 releasably with other closures 10 or Snap connections on the rear wall 7 and / or on the side walls 6 can be fixed. The two side walls 6 of the lower part 2 are pulled laterally past the cover 4 and form stacking posts 5. It may also be expedient to provide separately formed stacking posts 5 in the region of the side walls, the rear wall 7 and / or the front wall 9. On the front wall 9, a pivotable about an axis 33 in the direction of the arrow 32 carrying handle 31 is provided. The carrying handle 31 and the two closures 10 are sunk in the shown stationary or closed position with respect to the outer contour of the tool case. The cover 4 and the lower part 2 each have an opening 29, 30 in the region of the front wall 9, through which a padlock can be passed and whereby the cover 4 can be closed relative to the lower part 2. It may also be appropriate to arrange an integrated combination lock or the like. In the region of the lower part 2, the cover 4 and the side walls 6 means 12 are provided against slipping stacked tool box transverse to the vertical direction 1. The anti-slipping means 12 are described below.

Fig. 2 zeigt eine Variante des Werkzeugkoffers nach Fig. 1, von denen zwei Stück 34, 35 übereinander gestapelt sind und Mittel 23 zur formschlüssigen Verbindung in der Hochrichtung 1 von übereinander gestapelten Werkzeugkoffern aufweisen. Die Seitenwände 6 sind als Stapelpfosten 5 ausgebildet und weisen auf ihrer in der Hochrichtung 1 weisenden Oberseite 18 eine Ausnehmung 19 und auf ihrer gegenüberliegenden Unterseite 20 eine entsprechende Erhöhung 21 auf, die durch Druckflächen 22 seitlich begrenzt sind. Dabei greift die Erhöhung 21 des oberen Werkzeugkoffers 34 in die entsprechende Ausnehmung 19 des unteren Werkzeugkoffers 35 ein, wobei die jeweiligen Druckflächen 22 aneinander liegen und sich gegenseitig innerhalb der Ebene der Seitenwände 6 entgegen der Hochrichtung 1 und quer dazu abstützen. Die Abdeckung 4 des unteren Werkzeugkoffers 35 ist geschlossen und liegt zwischen seinen die Stapelpfosten 5 bildenden Seitenwänden 6 und weist gegenüber dem Unterteil 2 des aufgestapelten oberen Werkzeugkoffers 34 einen vertikalen, in der Hochrichtung 1 liegenden Abstand a auf. Fig. 2 shows a variant of the tool box after Fig. 1 of which two pieces 34, 35 are stacked on top of each other and have means 23 for positive connection in the vertical direction 1 of stacked tool cases. The side walls 6 are formed as stacking posts 5 and point on their upper side 18 pointing in the vertical direction 1 a recess 19 and on its opposite underside 20 a corresponding elevation 21, which are bounded laterally by pressure surfaces 22. In this case, the elevation 21 of the upper tool case 34 engages in the corresponding recess 19 of the lower tool case 35, wherein the respective pressure surfaces 22 abut each other and support each other within the plane of the side walls 6 against the vertical direction 1 and transversely thereto. The cover 4 of the lower tool box 35 is closed and lies between its the stacking posts 5 forming side walls 6 and has over the lower part 2 of the stacked upper tool box 34 a vertical, lying in the vertical direction 1 distance a.

In den Seitenwänden 6 ist eine Verriegelungsvertiefung 28 vorgesehen, in der angrenzend an die Oberseite 18 eine Rippe 25 und angrenzend an die Unterseite 20 eine Rippe 24 vorgesehen ist. Eine als Haltegriff 27 ausgebildete Klammer 26 aus spritzgegossenem Kunststoff ist in der Verriegelungsvertiefung 28 angeordnet, wobei die Klammer 26 von ihrer gestrichelt dargestellten Position in Richtung des Doppelpfeils 36 anhebbar bzw. in Richtung des Doppelpfeils 27 schwenkbar gelagert ist. Die Klammer 26 bildet zusammen mit den Rippen 24, 25 die Mittel 23 zur formschlüssigen Verbindung des oberen Werkzeugkoffers 34 mit dem unteren Werkzeugkoffer 35 in der Hochrichtung 1.In the side walls 6, a locking recess 28 is provided, in which adjacent to the top 18, a rib 25 and adjacent to the bottom 20, a rib 24 is provided. A constructed as a handle 27 clamp 26 made of injection-molded plastic is disposed in the locking recess 28, wherein the clip 26 is pivotally mounted from its position shown in dashed lines in the direction of the double arrow 36 and in the direction of the double arrow 27. The clamp 26 forms, together with the ribs 24, 25, the means 23 for the positive connection of the upper tool case 34 with the lower tool case 35 in the vertical direction 1.

Die Mittel 12 gegen Verrutschen quer zur Hochrichtung 1 an den Werkzeugkoffern 34, 35 umfassen des weiteren formschlüssig ineinandergreifbare Vorsprünge 13 und Führungsvertiefungen 14, die jeweils im Bereich der Vorderwand 9 und im Bereich der Rückwand 7 angrenzend an die Seitenwände 6 angeordnet sind. Die Vorsprünge 13 sind am jeweiligen Unterteil 2 angeordnet und bezüglich dessen Boden 40 hervorstehend ausgebildet, so daß sie bedarfsweise als Fuß genutzt werden können. Die Führungsvertiefungen 14 sind beidseitig in ihrer Längsrichtung offen, so daß ihre formschlüssige Stützwirkung im gestapelten Zustand quer zur Ebene der Seitenwände 6 eintritt.The means 12 against slipping transversely to the vertical direction 1 on the tool cases 34, 35 further comprise form-fitting interengageable projections 13 and guide recesses 14, which are respectively arranged in the region of the front wall 9 and in the region of the rear wall 7 adjacent to the side walls 6. The projections 13 are arranged on the respective lower part 2 and formed with respect to the bottom 40 protruding, so that they can be used as needed as a foot. The guide recesses 14 are open on both sides in their longitudinal direction, so that their positive support effect occurs in the stacked state transversely to the plane of the side walls 6.

Fig. 3 zeigt in einer ausschnittsweisen Schnittdarstellung die Anordnung nach Fig. 2, bei der die Klammer 26 des oberen Werkzeugkoffers 34 in einer Ruheposition gezeigt ist und in der Verriegelungsvertiefung 28 bezüglich der Außenkontur des Werkzeugkoffers 34 versenkt ist. In dieser Position kann die Klammer 26 am Haltegriff 27 gefaßt und der Stapel aus dem oberen Werkzeugkoffer 34 und dem unteren Werkzeugkoffer 35 angehoben werden. Im Bereich der oberen Rippe 25 ist ein Anschlag 38 für die in Richtung des Doppelpfeils 36 verschiebbare Klammer 26 vorgesehen. Im Bereich des unteren Werkzeugkoffers 35 ist die Klammer 26 in einer Position gezeigt, bei der sie durch eine kombinierte Hub- und Schwenkbewegung entlang der Pfeile 36, 37 (Fig. 2) die untere Rippe 24 des oberen Werkzeugkoffers 34 und die benachbarte obere Rippe 25 des unteren Werkzeugkoffers 35 umgreift und auf diese Weise einen Formschluß in der Hochrichtung 1 herstellt. Die formschlüssige Verbindung der Klammer 26 mit den Rippen 24, 25 kann klemmend oder rastend ausgeführt sein. Es kann auch zweckmäßig sein, ein elastisches Federelement zum Andrücken der Klammer 26 vorzusehen. Fig. 3 shows in a partial sectional view of the arrangement Fig. 2 in that the clip 26 of the upper tool box 34 is shown in a rest position and recessed in the locking recess 28 with respect to the outer contour of the tool box 34. In this position, the clip 26 can be grasped on the handle 27 and the stack of the upper tool box 34 and the lower tool box 35 can be raised. In the area of the upper rib 25, a stop 38 is provided for the clamp 26 displaceable in the direction of the double arrow 36. In the area of the lower tool box 35, the clamp 26 is shown in a position in which it is moved by a combined lifting and pivoting movement along the arrows 36, 37 (FIG. Fig. 2 ) engages around the lower rib 24 of the upper tool box 34 and the adjacent upper rib 25 of the lower tool box 35 and produces in this way a positive connection in the vertical direction 1. The positive connection of the clip 26 with the ribs 24, 25 may be designed to be clamped or latching. It may also be expedient to provide an elastic spring element for pressing the clip 26.

Fig.4 zeigt einen Werkzeugkoffer in einer Vorderansicht, bei dem die beiden zuvor beschriebene Verschlüsse 10 symmetrisch seitlich zur Mittellinie 11 versetzt angeordnet sind. Die Abdeckung 4 weist angrenzend an die Seitenwände 6 Führungsvertiefungen 14 auf, die mit seitlichen Abschrägungen 15 versehen sind. Am Unterteil 2 sind entsprechend geformte Vorsprünge 13 mit seitlichen Abschrägungen 15 zum Eingriff in die Führungsvertiefungen 14 eines darunter liegenden Werkzeugkoffers vorgesehen. Die am weitesten außen liegenden Führungsvertiefungen 14, die an die jeweiligen Seitenwände 6 angrenzen, sind derart ausgebildet, daß die entsprechenden Vorsprünge 13 eines darüberliegenden, nicht dargestellten Unterteils an die Innenseiten 39 der Seitenwände 6 zur Anlage gebracht werden können. Figure 4 shows a tool case in a front view, in which the two closures 10 described above are arranged symmetrically laterally offset from the center line 11. The cover 4 has adjacent to the side walls 6 on guide recesses 14, which are provided with lateral chamfers 15. At the lower part 2 correspondingly shaped projections 13 are provided with lateral chamfers 15 for engagement in the guide recesses 14 of an underlying tool case. The outermost guide grooves 14 adjacent to the respective side walls 6 are formed so that the corresponding projections 13 of an overlying lower part, not shown, can be brought into abutment with the inner sides 39 of the side walls 6.

Fig. 5 zeigt die Draufsicht des Werkzeugkoffers nach Fig. 4, bei dem die Führungsvertiefungen 14 jeweils im Bereich der Vorderwand 9 und der Rückwand 7 angeordnet sind. Ein Teil der Führungsvertiefungen 14 im Bereich der Vorderwand 9 sowie die entsprechenden Führungsvertiefungen 14 im Bereich der Rückwand 7 weisen jeweils Anschlagflächen 16 auf. Durch diese Anschlagflächen 16 sind die jeweils gegenüberliegenden Führungsvertiefungen 14 derart voneinander getrennt, daß ein Hindurchführen eines Vorsprungs 13 entlang ihrer Längsachse behindert ist. Die in diese Führungsvertiefungen 14 eingreifbaren Vorsprünge 13 sind im Zusammenhang mit der Fig. 6 näher beschrieben und weisen entsprechende Anschlagflächen 17 auf. Die Abdeckung 4 ist über drei Scharniere 8 an der Rückwand 7 des in den vorhergehenden Figuren näher gezeigten Unterteiles 2 schwenkbar festgelegt. Fig. 5 shows the top view of the tool box after Fig. 4 in which the guide depressions 14 are respectively arranged in the region of the front wall 9 and the rear wall 7. A portion of the guide recesses 14 in the region of the front wall 9 and the corresponding guide recesses 14 in the region of the rear wall 7 each have stop surfaces 16. Through these stop surfaces 16 the respective opposite guide recesses 14 are separated from each other so that a passage of a projection 13 along its longitudinal axis is obstructed. The engageable in this guide recesses 14 projections 13 are in connection with the Fig. 6 described in more detail and have corresponding stop surfaces 17. The cover 4 is fixed by three hinges 8 on the rear wall 7 of the lower part 2 shown in more detail in the preceding figures.

Fig. 6 zeigt in einer Seitenansicht den Werkzeugkoffer nach den Fig. 4 und 5, bei dem die Oberseite 18 der Seitenwand 6 konvex und die Unterseite 19 in entsprechender Weise konkav gekrümmt ist. Die Vorsprünge 13 im Bereich der Rückwand 7 und der Rückwand 9 des Unterteils 2 weisen innenseitig einander zugewandt Anschlagflächen 17 auf, die im gestapelten Zustand an den in Fig. 5 gezeigten Anschlagflächen 16 anliegen und eine Verrutschen in der Längsrichtung der Führungsvertiefungen 14 nach Fig. 5 vermeiden. Die Vorsprünge 13 stehen entgegen der Hochrichtung 1 gegenüber dem Boden 40 und der Erhöhung 21 in der Seitenwand 6 hervor und bilden dadurch Ablagefüße. Fig. 6 shows in a side view of the tool box after the Fig. 4 and 5 in which the upper side 18 of the side wall 6 is convex and the lower side 19 is correspondingly concavely curved. The projections 13 in the region of the rear wall 7 and the rear wall 9 of the lower part 2 have on the inside facing each other stop surfaces 17 which in the stacked state to the in Fig. 5 abut stop surfaces 16 shown and slipping in the longitudinal direction of the guide grooves 14 after Fig. 5 avoid. The projections 13 protrude against the vertical direction 1 relative to the bottom 40 and the elevation 21 in the side wall 6 and thereby form storage feet.

Fig. 7 zeigt in einer perspektivischen Übersichtsdarstellung eine Variante des erfindungsgemäßen Werkzeugkoffers, bei dem die Abdeckung 4 die gesamte Grundfläche des Unterteils 2 abdeckt mit Ausnahme des mittigen Bereichs der Seitenwände 6, die hier seitlich an der Abdeckung 4 vorbei hochgezogen sind und nur im Bereich der Ausnehmung 19 einen Stapelpfosten 5 bilden. Dabei sind die Druckflächen 22 an der Abdeckung 4 derart ausgebildet, daß sie zu den entsprechenden Druckflächen 22 an der untenseitigen Erhöhung 21 im gestapelten Zustand beabstandet sind und lediglich eine Sicherung gegen seitliches Verrutschen bilden. Ein gestrichelt angedeuteter Tragegriff 31 kann als Option an der Abdeckung 4 vorgesehen sein. Fig. 7 shows in a perspective overview representation of a variant of the tool case according to the invention, in which the cover 4 covers the entire base of the lower part 2 with the exception of the central region of the side walls 6, which are here laterally pulled up to the cover 4 over and only in Region of the recess 19 form a stacking post 5. In this case, the pressure surfaces 22 are formed on the cover 4 such that they are spaced from the corresponding pressure surfaces 22 at the bottom elevation 21 in the stacked state and form only a backup against lateral slippage. A dashed line indicated handle 31 may be provided as an option on the cover 4.

Eine weitere Variante ist in Fig. 8 gezeigt, bei denen an den Seitenwänden 6 elastische Stoßdämpfer 41 vorgesehen sind, die eine Stoßbelastung beispielsweise größerer Kofferstapel verringern.Another variant is in Fig. 8 shown in which elastic shock absorbers 41 are provided on the side walls 6, which reduce a shock load, for example, larger luggage stack.

Fig. 9 zeigt in einer perspektivischen Übersichtsdarstellung einem Werkzeugkoffer 34, der in Hochrichtung 1 auf ein darunterliegendes Schubfach 42 aufgestapelt ist. Das Schubfach 42 weist ein Gehäuseteil 43 auf, welches aus Seitenwänden 6 und einer zwischenliegenden, fest mit den Seitenwänden 6 verbundenen Abdeckung 4 besteht. Die Seitenwände 6 des Gehäuseteils 43 bilden Stapelpfosten 5 für den darüberliegenden Werkzeugkoffer 34. Zwischen die Stapelpfosten 5 ist horizontal entlang des Doppelpfeiles 45 eine Schublade 44 in das Gehäuseteil 43 einschiebbar bzw. aus ihm herausziehbar. Die durch die Stapelbildung auftretenden Gewichtskräfte werden durch die Stapelpfosten 5 aufgenommen, so daß die Schublade 44 im wesentlichen kraftfrei ist. In seinen weiteren Einzelheiten insbesondere im Bereich der Seitenwände 6 und der Abdeckung 4 ist das Gehäuseteil 43 vergleichbar zu den zuvor beschriebenen Werkzeugkoffern ausgeführt, um eine Stapelbildung mit den beschriebenen Vorteilen insbesondere bezüglich der Sicherung gegen seitliches Verrutschen zu ermöglichen. Fig. 9 shows in a perspective overview representation of a tool box 34 which is stacked in the vertical direction 1 on an underlying drawer 42. The drawer 42 has a housing part 43, which consists of side walls 6 and an intermediate, fixed to the side walls 6 cover 4. The side walls 6 of the housing part 43 form stacking posts 5 for the overlying tool box 34. Between the stacking post 5 is horizontally along the double arrow 45, a drawer 44 in the housing part 43 can be inserted or pulled out of it. The weight forces arising from the stacking are absorbed by the stacking posts 5, so that the drawer 44 is substantially free of force. In its further details, in particular in the region of the side walls 6 and the cover 4, the housing part 43 is comparable to executed the tool cases described above to allow stacking with the advantages described in particular with respect to the protection against lateral slipping.
