Description

Die Erfindung betrifft ein Eckenprofil gemäß dem Oberbegriff des Anspruchs 1 für den Stoß- und Lastschutz an den Ecken von verpackten Gegenständen.The invention relates to a corner profile according to the preamble of claim 1 for the shock and load protection at the corners of packaged objects.

Schutzecken (DE 91 11 983.9 U1, DE 87 00 167.5 U1) werden auf die Ecken von zu verpackenden Gegenständern aufgesetzt, um Stoß- und Stapellasteinwirkungen beim Transport oder der Lagerung der verpackten Gegenstände zu kompensieren. Da die bei der Stapelung der Gegenstände auftretenden Eckenbelastungen sehr groß werden können, müssen die Wandstärke und die Seitenflächen der Schutzecken sehr groß dimensioniert werden, was einen großen Materialaufwand sowohl hinsichtlich Herstellung als auch Entsorgung bedeutet.Protective corners (DE 91 11 983.9 U1, DE 87 00 167.5 U1) are placed on the corners of articles to be packaged in order to compensate for shock and stacking effects during transport or storage of the packaged objects. Since the corner loads occurring in the stacking of the items can be very large, the wall thickness and the side surfaces of the protective corners must be very large, which means a large amount of material both in terms of production and disposal.

Schutzecken in der eingangs beschriebenen Ausgestaltung werden aus einem Zylinder aus Schaumstoff so herausgeschnitten, dass die Außenfläche und die Innenfläche durch eine Fortsatzfläche verbunden sind, die Teil der Zylinderwand ist und in drei konvex gekrümmten Endkanten ausläuft, die in den von der Achslinie und den Außenkanten der Außenpyramide gebildeten Ebenen unter einem rechten Winkel aneinander stoßen.Protective corners in the embodiment described above are cut out of a cylinder of foam so that the outer surface and the inner surface are connected by an extension surface which is part of the cylinder wall and terminates in three convexly curved end edges in the axis line and the outer edges of the Outside pyramid formed levels at a right angle to each other.

Aus der US 4 838 427 ist ein Eckenprofil gemäß dem Oberbegriff des Anspruchs 1 bekannt, das ein pyramidenartiges Lastverteilungselement aufweist, auf dessen Innenseite eine selbstklebende Plastikschaumschicht vorgesehen ist. Die Plastikschaumschicht wird vorzugsweise durch ein Vakuumansaugen, als selbstklebende Schicht oder durch Aufsprühen auf die innere Fläche des Lastverteilungselements aufgebracht.From US 4,838,427 a corner profile according to the preamble of claim 1 is known which comprises a pyramid-type load distribution element, on the inside of which a self-adhesive plastic foam layer is provided. The plastic foam layer is preferably applied by vacuum suction, as a self-adhesive layer or by spraying onto the inner surface of the load distribution element.

Der Erfindung liegt die Aufgabe zugrunde, ein Eckenprofil der eingangs beschriebenen Art zu schaffen, mit dem sich bei reduziertem Materialaufwand für die Schutzecke aus Schaumstoff und unter Gewährleistung einer ausreichenden Schutzfunktion hohe Stoß- und Druckbelastungen kompensieren lassen.The invention has for its object to provide a corner profile of the type described above, which can be used to compensate for high shock and pressure loads with reduced material costs for the corner protection foam and while ensuring adequate protection.

Erfindungsgemäß wird diese Aufgabe dadurch gelöst, dass auf der Außenfläche der Schutzecke ein Lastverteilungselement aus steifem Material in Form einer dreiseitigen Pyramide mit dreieckigen Seitenflächen und drei Pyramidenkanten gehalten ist, wobei jede Pyramidenkante eine Länge hat, die zwischen der Länge der Außenkante der Außenpyramide und der doppelten Wandstärke des Schaumstoffs liegt, und das Lastverteilungselement innen an seinen Pyramidenkanten Vorsprünge für einen lösbaren Halteeingriff mit den Außenkanten des Schaumstoffs der Außenpyramide aufweist.According to the invention this object is achieved in that on the outer surface of the protective corner, a load distribution element made of rigid material in the form of a three-sided pyramid is held with triangular side surfaces and three pyramid edges, each pyramid edge has a length which is between the length of the outer edge of the outer pyramid and the double wall thickness of the foam, and the load distribution member has inside at its pyramid edges projections for releasably retaining engagement with the outer edges of the foam of the outer pyramid.

Eine bevorzugte Ausführungsform der Erfindung sieht vor, dass das Lastverteilungselement aus einem dünnen Blech- oder Hartkunststoffmaterial besteht, wobei im letzteren Fall das Lastverteilungselement vorzugsweise durch Spritzgießen hergestellt wird. Ein solches Lastverteilungselement kann auch nach Verschleiß der Schutzecke weiter verwendet werden, beispielweise zum Schutz vom Ecken an Möbelstücken.A preferred embodiment of the invention provides that the load distribution element consists of a thin sheet metal or hard plastic material, wherein in the latter case the load distribution element is preferably produced by injection molding. Such a load distribution element can continue to be used after wear of the protective corner, for example, to protect the corners of furniture.

Wenn die Außenfläche und die Innenfläche der Schutzecke durch eine Fortsatzfläche verbunden sind, die von zur Achsenlinie parallel verlaufenden Mantellinien begrenzt ist und die zueinander rechtwinklige Endkanten aufweist, ergeben sich dadurch Einsparungen im Bereich des Schaumstoffs, dass die Seitenflächen der Außenfläche und der Innenfläche im Wesentlichen quadratisch sind, wodurch jeweils sechs jeweils rechtwinklig aneinandersto-βende Endkanten gebildet werden, von denen jeweils zwei aneinandergrenzende in ein und derselben Ebene liegen. In dieser Ausgestaltung lässt sich die Schutzecke aus einem Schaumstoffprisma mit einem Querschnitt in Form eines gleichseitigen Sechsecks so ausschneiden, dass die Fortsatzfläche ein Teil der Prismaaußenwand ist, was gegenüber, der bekannten Herstellung aus einem Schaumstoffzylinder eine Materialeinsparung von 10% und mehr ergibt. Dabei stehen die quadratischen Seitenflächen der Schutzecke über die auf ihr angeordneten dreieckigen Seitenflächen des Lastverteilungselements vor und sorgen für eine weiter erstreckte Umfassung einer Ecke eines verpackten Gegenstandes mit Schaumstoff.When the outer surface and the inner surface of the guard corner are connected by an extension surface bounded by generatrices parallel to the axis line and having mutually perpendicular end edges, this results in savings in the area of the foam such that the side surfaces of the outer surface and the inner surface are substantially square are, whereby each six perpendicular abeinandersto-βende end edges are formed, of which two adjacent lie in one and the same plane. In this embodiment, the protective corner of a foam prism with a cross section in the form of an equilateral hexagon cut so that the extension surface is part of the Prismaaußenwand, which compared to the known production of a foam cylinder results in a material saving of 10% and more. In this case, the square side surfaces of the protective corner protrude over the triangular side surfaces of the load-distributing element arranged on it and ensure that a corner of a packaged object with foam continues to extend.

Der Schaumstoff der Schutzecke besteht zweckmäßigerweise aus geschäumtem Polyethylen, Polystyrol, Polypropylen, thermoplastischen Elastomeren oder Kombinationen daraus.The foam of the protective corner is expediently made of foamed polyethylene, polystyrene, polypropylene, thermoplastic elastomers or combinations thereof.

Die von der Innenfläche und der Fortsatzfläche der Schutzecke gebildeten Endkanten sind vorzugsweise nach innen abgeflacht.The end edges formed by the inner surface and the extension surface of the protective corner are preferably flattened inwardly.

Das erfindungsgemäße Eckenprofil in Form der Kombination der Schutzecke mit dem darauf angebrachten Lastverteilungselement sorgt für eine hohe Stoßabsicherung und Lastaufnahmefähigkeit ohne Veränderung der Dämpfungswirkung, da durch das nicht elastische starre Lastverteilungselement die Krafteinwirkung auf einen großen Flächeanteil des Schaumstoffs der Schutzecke übertragen wird. Dadurch kann die Wandstärke der Schutzecke ohne eine nennenswerte Beeinträchtigung ihrer Schutzfunktion verringert werden, was den Schaumstoffeinsatz weiter reduziert. Ferner ist das Lastverteilungselement von der Schutzecke abnehmbar und bei Verschleiß des Schaumstoffs wiederverwendbar ausgebildet.The corner profile according to the invention in the form of the combination of the protective corner with the load distribution element mounted thereon ensures a high shock protection and load capacity without changing the damping effect, since the non-elastic rigid load distribution element, the force is transmitted to a large surface area of the foam of the protective corner. As a result, the wall thickness of the protective corner can be reduced without a significant impairment of its protective function, which further reduces the use of foam. Further, the load distribution member is detachable from the protective corner and reusable upon wear of the foam.

Fig. 1 zeigt ein Eckenprofil mit einer Schutzecke aus Schaumstoff, die eine Außenfläche 2 und Innenfläche 4 hat, die in einem einer vorgegebene Wandstärke s entsprechenden Abstand angeordnet und aus im Wesentlichen senkrecht zueinander angeordneten Seitenflächen unter Bildung einer Außenpyramide mit drei Außenkanten 3 und einer Innenpyramide mit drei Innenkanten 7 zusammensetzt sind. Die Spitzen 6 und 6' der Außenpyramide und der Innenpyramide liegen dabei auf einer Achsenlinie 11.Fig. 1 shows a corner profile with a protective corner of foam, which has an outer surface 2 and inner surface 4 arranged in a predetermined wall thickness s corresponding distance and substantially mutually perpendicular side surfaces to form an outer pyramid with three outer edges 3 and an inner pyramid are composed with three inner edges 7. The tips 6 and 6 'of the outer pyramid and the inner pyramid lie on an axis line eleventh

Das Eckenprofil von Fig. 1 und Fig. 5 hat ferner ein auf der Außenfläche 2 der Schutzecke aus Schaumstoff formschlüssig angeordnetes Lastverteilungselement 8 aus einem steifen dünnen Material, das die Form einer dreiseitigen Pyramide mit dreieckigen Seitenflächen und drei Pyramidenkanten 9 hat, wobei jede Pyramidenkante 9 eine Länge hat, die zwischen der Länge der Außenkante 3 der Außenpyramide und der doppelten Wandstärke s des Schaumstoffs liegt.The corner profile of Fig. 1 and Fig. 5 further has a on the outer surface 2 of the protective corner of foam form-fitting load distribution element 8 of a stiff thin material, which has the shape of a three-sided pyramid with triangular side surfaces and three pyramid edges 9, each pyramid edge. 9 has a length which is between the length of the outer edge 3 of the outer pyramid and the double wall thickness s of the foam.

Das Lastverteilungselement 8 besteht aus einem tragfähigen harten Material, wie zum Beispiel Blech oder hartem Kunststoff. Dadurch hat das Eckenprofil eine hohe Außenstabilität, wobei das Lastverteilungselement 8 Stoß- und Lasteinwirkungen flächenmäßig verteilt auf die Schutzecke aus Schaumstoff überträgt, wodurch deren Wandstärke s verglichen mit einer Schutzecke gleicher Dämpfungswirkung ohne Lastverteilungselement wesentlich reduziert werden kann.The load distribution element 8 is made of a load-bearing hard material, such as sheet metal or hard plastic. As a result, the corner profile has a high degree of external stability, with the load distribution element 8 distributed in terms of area by impact and load the protective corner of foam transfers, whereby its wall thickness s can be substantially reduced compared to a protective corner equal damping effect without load distribution element.

Für einen lösbaren Hafteingriff mit der Außenkante 3 der Außenpyramide ist an jeder Pyramidenkante 9 des Lastverteilungselements 8 innen wenigstens ein Vorsprung 12 vorgesehen. Wie in Fig. 2 gezeigt ist, sind dabei die Vorsprünge 12 vom Lastverteilungselement 8 aus nach innen gerichtet und können durch Spritzgießen oder durch Bearbeitung des Lastverteilungselements 8, zum Beispiel durch Schneiden, Sägen oder Prägen, hergestellt werden.For a detachable adhesive engagement with the outer edge 3 of the outer pyramid, at least one projection 12 is provided on each pyramid edge 9 of the load distribution element 8 inside. As shown in FIG. 2, the projections 12 are directed inwardly from the load distribution element 8 and can be produced by injection molding or by machining the load distribution element 8, for example by cutting, sawing or embossing.

Wie in Fig. 3 gezeigt ist, sind die Außenfläche 2 und die Innenfläche 4 der Schutzecke durch eine Fortsatzfläche 5 miteinander verbunden, die von zur Achsenlinie 11 parallel verlaufenden Mantellinien begrenzt wird und die zueinander rechtwinklige Endkanten 10 aufweist. Die Seitenflächen der Außenfläche 2 und der Innenfläche 4 sind im Wesentlichen quadratisch ausgebildet, wodurch jeweils sechs jeweils rechtwinklig aneinanderstoßende Endkanten 10 gebildet werden, von denen jeweils zwei aneinandergrenzende in ein und derselben Ebene liegen. Die gezeigte Schutzecke von Fig. 3 wird vorzugsweise aus einem Schaumstoffprisma mit einem Querschnitt in Form eines gleichseitigen Sechsecks so ausgeschnitten, dass die Fortsatzfläche 5 ein Teil der Prismaaußenwand ist.As shown in Fig. 3, the outer surface 2 and the inner surface 4 of the protective corner by an extension surface 5 are interconnected, which is bounded by parallel to the axis line 11 generatrices and having mutually perpendicular end edges 10. The side surfaces of the outer surface 2 and the inner surface 4 are formed substantially square, whereby in each case six respectively abutting end edges 10 are formed at right angles, of which two adjoining lie in one and the same plane. 3 is preferably cut from a foam prism having a cross-section in the shape of an equilateral hexagon so that the extension surface 5 is part of the prism outer wall.

Die in Fig.3 und Fig. 4 gezeigte Schutzecke wird aus dem Sechskantprisma mittels drei in einem Punkt zusammenstoßender eckiger Schneidwerkzeuge geschnitten. Die Innenkanten 7 der Innenpyramide und die Außenkanten 3 der Außenpyramide sind dabei so ausgerichtet, dass sie mit den Ecken des Prismas im Wesentlichen übereinstimmen.The protective corner shown in Fig. 3 and Fig. 4 is cut from the hexagonal prism by means of three angular cutting tools colliding at one point. The inner edges 7 of the inner pyramid and the outer edges 3 of the outer pyramid are aligned so that they substantially coincide with the corners of the prism.

Bei einer Modifizierung der Schutzecke werden die von der Innenfläche 4 und der Fortsatzfläche 5 gebildeten Endkanten 10 so abgeschnitten, dass jeweils nach innen gerichtete Abflachungen 13 gebildet werden, die in Fig. 5 zu sehen sind und von denen eine in Fig. 3 durch die strichpunktierte Linie 13 angedeutet ist. Dadurch kann eine Verformung der Schutzecke vermieden werden, die sich ergeben könnte, wenn die dünn auslaufenden Endkanten 10 mit dem zu schützenden Gegenstand in Eingriff gebracht werden.In a modification of the protective corner formed by the inner surface 4 and the extension surface 5 end edges 10 are cut so that in each case inwardly directed flats 13 are formed, which can be seen in Fig. 5 and one of which in Fig. 3 by the dash-dotted lines Line 13 is indicated. Thereby, a deformation of the protective corner can be avoided, which could result if the thin leaking end edges 10 are brought into engagement with the object to be protected.
