Die Erfindung betrifft einen Metallkoffer nach dem Oberbegriff des Anspruchs 1 sowie ein verfahren zur Herstellung eines Metallkoffers nach dem Oberbegriff des Anspruchs 7.The invention relates to a metal case according to the Preamble of claim 1 and a method for Manufacture of a metal case according to the generic term of claim 7.

Es sind Koffer aus Metall bekannt (DE 32 46 510 A1), die aus zwei einstückig hergestellten Schalenhälften bestehen, die beispielsweise aus einem tiefgezogenem Blech geformt sind. Ein derartiges Herstellverfahren ist insbesondere bei Verwendung von hochfesten Aluminiumlegierungen sehr kostenaufwendig.Cases made of metal are known (DE 32 46 510 A1), the one-piece shell halves consist, for example, of a deep-drawn Sheet metal are formed. Such a manufacturing process is particularly useful when using high-strength aluminum alloys very expensive.

Es ist ferner bekannt, Kofferschalen (DE-PS 835506) aus einem einstückigen Blech zu fertigen, das an den Ecken ausgestanzt ist, wobei die Schmalseiten, die Oberseite und die Standfläche jeweils durch Umbiegen des einstückigen Bleches hergestellt werden. Zur Stabilisierung und zur Überdeckung der Stanzschnitte müssen die umgebogenen Wandelemente an den Ecken mit Verbindungselementen verbunden werden, die gleichzeitig als Eckenschutz dienen. Des weiteren werden die Wandelemente in der Trennebene zwischen den Kofferhälften jeweils mit einem stabilisierenden Rahmenelement gehalten. Die Herstellung eines solchen Koffers erfordert ebenfalls einen hohen Fertigungsaufwand mit einem hohen Anteil manueller Fertigungsschritte.It is also known to make case shells (DE-PS 835506) to produce a one-piece sheet metal that at the corners is punched out, the narrow sides, the top and the footprint by bending the one-piece Sheets are made. For stabilization and to cover the die cuts, the bent wall elements at the corners with connecting elements connected, which also serves as corner protection to serve. Furthermore, the wall elements in the parting line between the case halves held a stabilizing frame element. The production such a suitcase also requires a high manufacturing effort with a high proportion manual manufacturing steps.

Aus der DE 16 79 329 U ist ein Verfahren zur Herstellung eines Metallkoffers bekannt, bei dem ein einstückiges Wandelement aus einer Platte hergestellt wird, wobei Breit- und Oberseite durch einmaliges Umbiegen der Platte gebildet werden. Ein weiteres Wandelement wird mit dem erstgenannten Wandelement mit einer Doppelfalz verbunden.DE 16 79 329 U describes a process for the production known a metal case, in which a one-piece Wall element is made from a plate, wherein Wide and top side by bending the Plate are formed. Another wall element is with the former wall element with a double fold connected.

Aus der US-A-2,950,792 ist ein Metallkoffer bekannt, der aus zwei Kofferhälften mit jeweils einer Breitseite, zwei gegenüberliegenden Schmalseiten, einer Oberseite und einer Standfläche besteht. Im Schließzustand greifen die Kofferhälften über einen durch die Schmalseiten, die Oberseite und die Standfläche verlaufenden Rahmen ineinander und die Kofferhälften sind in der Standfläche gelenkig miteinander verbunden. Jede Kofferhälfte ist aus zwei einstückigen Wandelementen gebildet. Das erste Wandelement besteht aus einem streifenförmigen Stranggußprofil mit einem an einer Längskante angeformten Wandaufnahmeprofil und mit einem an der gegenüberliegenden Längskante angeformten Rahmenprofil. Das zweite Wandelement besteht aus einem plattenförmigen Blech.A metal case is known from US-A-2,950,792, that of two suitcase halves, each with a broad side, two opposite narrow sides, one top and there is a stand area. Grab in the closed state the case halves over one through the narrow sides, the top and the standing surface The frames fit into each other and the case halves are in the Stand area hinged together. Each Half of the case consists of two one-piece wall elements educated. The first wall element consists of a strip-shaped Continuous cast profile with one on one longitudinal edge molded wall mounting profile and with a the opposite longitudinal edge molded frame profile. The second wall element consists of a plate-shaped Sheet.

Der Erfindung liegt die Aufgabe zugrunde, einen Metallkoffer, sowie ein Verfahren zu seiner Herstellung derart weiterzubilden, daß eine kostengünstigere und besser automatisierbare Fertigung möglich ist.The invention has for its object a metal case, and a method for its production to train that a cheaper and production that is easier to automate is possible.

Zur Lösung dieser Aufgabe dienen erfindungsgemäß die Merkmale der Ansprüche 1 bzw. 7. According to the invention, to solve this problem Features of claims 1 and 7 respectively.

Jede Kofferhälfte des Metallkoffers wird nach der Erfindung aus zwei Wandelementen gebildet, wobei das eine Wandelement aus einem streifenförmigen Material besteht, das an einer Längskante ein Wandaufnahmeprofil und an der gegenüberliegenden Längskante ein Rahmenprofil aufweist. Das streifenförmige Wandelement wird in einem Arbeitsvorgang aus einem Stranggußprofil hergestellt.Each case half of the metal case is after the Invention from two wall elements formed, the one wall element from a strip-shaped material that is attached to a Long edge a wall mounting profile and on the opposite longitudinal edge a frame profile having. The strip-shaped wall element is in one Working process made from a continuous cast profile.

Das streifenförmige erste Wandelement bildet die sich gegenüberliegenden Schmalseiten und die Standfläche. Das plattenförmige zweite Wandelement bildet die Breitseite und die zugehörige Oberseite. Das zweite Wandelement ist gebogen in das Wandaufnahmeprofil des ersten Wandelementes eingesteckt und in dem Wandaufnahmeprofil des ersten Wandelementes zum Zusammenfügen der jeweiligen Wandelementen festgeklemmt.The strip-shaped first wall element is formed opposite narrow sides and the footprint. The plate-shaped second wall element forms the broad side and the associated top. The second wall element is bent into the wall mounting profile of the first Wall element inserted and in the wall mounting profile of the first wall element for joining the respective Wall elements clamped.

Ein wesentlicher Vorteil der Erfindung und des erfindungsgemäßen Verfahrens besteht darin, daß die Wandelemente für Koffer unterschiedlicher Größe verwendet werden können, indem in einfacher Weise nur Ihre Länge entsprechend der Koffergröße beschnitten wird. So kann das erste Wandelement beispielsweise in Coils angeliefert werden, wobei unterschiedliche Koffer mit dem gleichen Stranggußprofil hergestellt werden können. An essential advantage of the invention and that of the invention The method is that the wall elements used for suitcases of different sizes can be done by simply changing your length is trimmed according to the case size. So can the first wall element delivered in coils, for example be, different cases with the same continuous casting profile can be produced.

Das gleiche gilt für das zweite Wandelement, das ebenfalls bezogen auf eine vorgegebene Breite in der Länge beschnitten werden kann. So ist es beispielsweise möglich, die zweiten Wandelemente der beiden ungleich tiefen Kofferhälften aus dem gleichen Blech herzustellen. Auf diese Weise ist die Vorratshaltung von Profilen und Blechen für unterschiedliche Koffergrößen erheblich reduziert, so daß die Fertigungskosten und letztlich auch der Platzbedarf verringert werden.The same applies to the second wall element, which also based on a given width in length can be cropped. For example, it is possible the second wall elements of the two unequal to manufacture deep case halves from the same sheet. This is how profiles are stocked and sheets for different case sizes considerably reduced so that the manufacturing costs and ultimately, the space requirement can also be reduced.

Das zweite Wandelement wird ohne Wandaufnahme- und Rahmenprofil aus einem plattenförmigen Blech ausgebildet und zur Bildung einer Breitseite des Metallkoffers mit zugehöriger Oberseite einmal gebogen.The second wall element is without wall mounting and Frame profile formed from a plate-shaped sheet and to form a broad side of the metal case bent once with the associated top.

Die Montage des Metallkoffers erfolgt durch einfaches Zusammenstecken des zweiten Wandelementes in die Wandaufnahmeprofile des ersten Wandelementes, die zum festen Verbinden der Wandelemente mit einem geeigneten Werkzeug zusammengedrückt werden können.The assembly of the metal case is easy Put the second wall element together in the wall mounting profiles of the first wall element to the fixed Connect the wall elements with a suitable tool can be squeezed together.

Vorzugsweise ist vorgesehen, daß das Wandaufnahmeprofil mit einer Lasche jeweils am freien Ende der Schmalseiten, freigestanzt ist und bis an die Stirnkante der Schmalseiten, mit einem Übergangsradius gebogen ist, wobei die Lasche des Wandaufnahmeprofils jeweils an der Schmalseite ist.It is preferably provided that the wall mounting profile with a tab at the free end of the narrow sides, is punched free and up to the front edge of the Narrow sides, is bent with a transition radius, the tab of the wall mounting profile on the Is narrow side.

Die Kofferhälften des Metallkoffers können somit auf einfache Weise mit Hilfe von zwei einstückigen Wandelementen zusammengefügt werden. The case halves of the metal case can thus be opened simple way with the help of two one-piece wall elements be put together.

Das erfindungsgemäße Verfahren sieht im einzelnen vor:

  • das Bilden eines ersten, einstückigen Wandelementes durch das Herstellen eines streifenförmigen Stranggußprofils, mit einem längs einer Kante angeformten Wandaufnahmeprofil und einem längs der gegenüberliegenden Kante angeformten Rahmenprofil
  • das Ausstanzen eines Endstückes an beiden Enden des Stranggußprofils derart, daß über das freie Ende hinaus jeweils ein entsprechend der Breite des Stranggußprofils langes Wandaufnahmeprofil mit einer Befestigungslasche verbleibt,
  • das Umbiegen der Wandaufnahmeprofile um die freien Enden des Stranggußprofils,
  • das Verbinden der Befestigungslaschen mit den freien Enden des Stranggußprofils,

The standing surface 12a, 12b instructs its end facing away from the handle 9 two rollers 15 on, which make it possible in connection with the handle 9 the suitcase in a one-sided manner to roll.

Die beiden Kofferhälften 2, 4 sind unsymmetrisch, weisen also jeweils eine unterschiedliche Tiefe auf. Die Kofferhälften 2, 4 sind in der Standfläche 12a, 12b über ein oder mehrere längs der Standfläche 12a, 12b verlaufende Scharniere 5 miteinander verbunden, wobei ein Scharnierelement mit der Standfläche 12a und das andere Scharnierelement fest mit der Standfläche 12b verbunden ist.The two case halves 2, 4 are asymmetrical, point so each has a different depth. The Case halves 2, 4 are in the standing area 12a, 12b over one or more along the base 12a, 12b extending hinges 5 interconnected, wherein a hinge element with the base 12a and that other hinge element fixed to the base 12b connected is.

Die Breitseite 6a und die Oberseite 10a der Kofferhälfte 2, sowie die Breitseite 6b und die Oberseite 10b der zweiten Kofferhälfte 4 bestehen jeweils aus einer einstückigen Platte, die mit einer rippenförmigen Profilierung 25 versehen sein kann, die sowohl eine Versteifungsfunktion als auch eine ästhetische Funktion ausübt. Diese Platte bildet ein zweites Wandelement 16, das in das Wandaufnahmeprofil 18 des ersten Wandelementes 14a, 14b gebogen einsteckbar ist. Dabei ist es möglich, eine unflexible Platte, die mit Hilfe eines Preßwerkzeugs einmal zur Bildung der Breit- bzw. Oberseite gebogen wird, oder eine flexible Platte, die während des Zusammenfügens der beiden Wandelemente 14, 16 gebogen wird, ohne daß ein separater Biegevorgang vorgeschaltet sein müßte, einzusetzen.The broad side 6a and the top 10a of the case half 2, and the broad side 6b and the top 10b the second case 4 each consist of one one-piece plate with a rib-shaped profile 25 can be provided, both a stiffening function as well as an aesthetic function exercises. This plate forms a second wall element 16, that in the wall mounting profile 18 of the first wall element 14a, 14b can be inserted bent. It is possible an inflexible plate made with the help of a press tool once to form the broad or top is bent, or a flexible plate that during the joining of the two wall elements 14, 16 bent is preceded without a separate bending process should be to use.

Die sich gegenüberliegenden Schmalseiten 8a, 8b und die Standflächen 12a, 12b werden aus zwei unterschiedlich breiten streifenförmigen Wandelementen 14a, 14b gebildet, die jeweils an einer Längskante ein Wandaufnahmeprofil 18 zur Aufnahme des zweiten Wandelementes 16a, 16b und auf der dem Wandaufnahmeprofil 18 gegenüberliegenden Längskante ein Rahmenprofil 20 bzw. 21 aufweisen.The opposite narrow sides 8a, 8b and Stand areas 12a, 12b become different from two wide strip-shaped wall elements 14a, 14b are formed, each with a wall mounting profile on one longitudinal edge 18 for receiving the second wall element 16a, 16b and on the wall receiving profile 18 opposite Longitudinal edge have a frame profile 20 or 21.
