Abstract

A palette made from two metal frames and held together by spacer elements is clad in a thermo-plastic material. The plastic cladding provides protection against corrosion and also improves the hygienic aspects of the palette. The spacer which couple the two frames can have the form of a screw pin with left and right hand screwed ends. The load carrying upper palette frame has a larger number of frame work members than the lower frame. By heating the contact areas of the upper and the lower cladding, they can be joined to form a sealed unit.

Description

Palette " Die Erfindung bezieht sich auf eine mit einem thermoplastischen Material ummantelte Palette. Palette "The invention relates to one with a thermoplastic Material covered pallet.

Es sind Flachpaletten aus einem mit einem thermoplastischen Material umspritzten Stahlgitter bekannt, Des weiteren werden Paletten häufig nach einem Vakuumverfahren mit Kunststoff überzogen, bei dem ein über das Gitter gelegter thermoplastischer Zuschnitt mit Unterdruck um und unter die Gitterteile gelegt wird. Die Tragfähigkeit solcher Paletten ist jedoch begrenzt.They are flat pallets made of a thermoplastic material molded steel grid known, Furthermore, pallets are often after a Vacuum process covered with plastic, in which a thermoplastic is placed over the grid Blank is placed around and under the grid parts with negative pressure. The carrying capacity however, such pallets are limited.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Palette mit erheblich größerer Tragfähigkeit zu schaffen.The invention is therefore based on the object of a range with significantly to create greater load-bearing capacity.

Die Lösung dieser Aufgabe besteht in einer Palette aus zwei getrennten, durch Abstandhalter miteinander verbundenen Gittern. Eine solche Palette läßt sich im Vakuum oder durch Spritzen mit Kunststoff umhüllen.The solution to this problem consists in a pallet of two separate, grids connected to one another by spacers. Such a palette can Envelop with plastic in a vacuum or by injection molding.

Die Abstandhalter besitzen vorzugsweise einen kreisförmigen Querschnitt und können aus zwei Steckteilen, beispielsweise einem rohrförmigen Teil und einem Rundstab bestehen. Auf diese Weise ergibt sich in Abhängigkeit von der Einstecklänge eine hohe Steifigkeit.The spacers preferably have a circular cross-section and can consist of two plug-in parts, for example a tubular part and a Round rod exist. This results in a function of the insertion length high rigidity.

Die besonderen Vorteile der erfindungsgemäßen Palette liegen in ihrer hohen Festigkeit bzw. Steifigkeit; sie ist zudem in Anbetracht der Kunststoffummantelung äußerst hygienisch und wesentlich maßhaltiger als beispielsweise Holzpaletten.The particular advantages of the pallet according to the invention lie in their high strength or rigidity; it is also in view of the plastic coating extremely hygienic and much more dimensionally stable than, for example, wooden pallets.

Die Erfindung wird nachfolgend anhand von in der Zeichnung dargestellten Ausführungsbeispielen des näheren erläutert. In der Zeichnung zeigen: Fig, 1. 3. 5. 7. 10 und 12 Paletten mit unterschiedlichen Abstandhaltern, Fige 2. 4. 6. 8. 9. II. 11a und 13 unterschiedliche Abstandhalter.The invention is illustrated below with reference to in the drawing Embodiments of the explained in more detail. The drawing shows: FIG. 1, 3. 5. 7. 10 and 12 pallets with different spacers, Fig. 2. 4. 6. 8. 9. II. 11a and 13 different spacers.

Die in Fig0 1 dargestellte Palette besteht aus zwei Gitterböden 1 und 2 mit Stahlstreben 3, 40 Die Streben sind mit einem thermoplastischen Material 5, 6, beispielsweise Polyäthylen, umhüllt, das ein Anhaften von Schmutz und Feuchtigkeit verhindert und somit der Palette ein gefälliges Aussehen verleiht sowie die Streben vor Beschädigungen schützt Die beiden Gitterböden 1, 2 sind von unterschiedlicher Beschaffenheit; so besitzt der obere Boden eine durchgehende Oberfläche 7 als Tragfläche und zur Erhöhung der Tragfestigkeit eine größere Anzahl Querstreben als der Unterboden 2, während der Unterboden lediglich als Stellfläche fungiert und daher keine durchgehende Oberfläche erfordert, Beim Herstellen einer Palette gemäß Fig. 1 werden der Ober- und der Unterboden 1, 2 mit Hilfe von sich senkrecht zu den Böden erstreckenden Stahlstiften und -büchsen 10, 11 miteinander verbunden. Die Stahlstifte und -büchsen können in beliebiger Verteilung an beiden Böden angeordnet sein. Im zusammengebauten Zustand bilden die Stifte und Büchsen Kupplungen, die den Unter-und Oberboden starr miteinander verbinden.The pallet shown in Fig0 1 consists of two grid floors 1 and 2 with steel struts 3, 40 The struts are made with a thermoplastic material 5, 6, for example polyethylene, envelops the adhesion of dirt and moisture prevented and thus gives the pallet a pleasing appearance as well as the struts protects against damage The two grid floors 1, 2 are different Nature; so the upper floor has a continuous surface 7 as a support surface and a greater number of cross struts than the sub-floor to increase the load-bearing capacity 2, while the sub-floor only functions as a shelf and is therefore not a continuous one Requires surface, When manufacturing a pallet according to Fig. 1, the upper and the sub-floor 1, 2 with the aid of extending perpendicular to the floors Steel pins and bushes 10, 11 connected to one another. The steel pins and bushes can be arranged in any distribution on both floors. in the When assembled, the pins and bushings form the couplings that hold the lower and lower ends Rigidly connect the topsoil with each other.

Aus der Darstellung in Fig. 2 ist ersichtlich, daß die Abstandhalter 10, 11 mit thermoplastischem Material umhüllt sind; so besitzt die Kupplungsbüchse 11 über ihre gesamte Länge eine thermoplastische Ummantelung, während der Kupplungsstift 10 nur in seinem freiliegenden Teil, d.h. im wesentlichen dort, wo er mit dem Oberboden 1 verschweißt ist, eine Kunststoffummantelung aufweist, Da die Stifte mit den zugehörigen Büchsenöffnungen nicht unbedingt fluchten, ergibt sich nach dem Zusammenbau der beiden Palettenteile ein fester Reibungssitz. Die thermoplastische Ummantelung kann vor dem Zusammenbau der Palettenteile an den Berührungsflächen erwärmt werden, um beim Zusammenbau ein festes Verschweißen der Berührungsflächen zu erreichen und auf diese Weise die beiden Böden bleibend und fest miteinander zu verbinden.From the illustration in Fig. 2 it can be seen that the spacers 10, 11 are covered with thermoplastic material; so has the coupling sleeve 11 a thermoplastic sheath over its entire length, while the coupling pin 10 only in its exposed part, i.e. essentially where it meets the topsoil 1 is welded, has a plastic coating, Since the pins with the associated Bushing openings do not necessarily align, results after assembling the a tight friction fit on both pallet parts. The thermoplastic sheath can before the assembly of the pallet parts on the contact surfaces are heated to to achieve a solid welding of the contact surfaces during assembly and in this way the two floors are permanently and firmly connected to one another.

Die Paletten der Fig. 3, 5, 7, 10 und 12 stimmen im Grundaufbau mit der zuvor beschriebenen Palette überein und sind insoweit mit denselben Bezugsziffern gekennzeichnet.The pallets of FIGS. 3, 5, 7, 10 and 12 agree in the basic structure correspond to the pallet described above and are given the same reference numerals marked.

Bei der Palette nach den Fig. 3 und 4 besitzen der Ober-und der Unterboden jeweils rechtwinklig abstehende und mit thermoplastischem Material umhüllte Stahlbüchsen.In the case of the pallet according to FIGS. 3 and 4, the upper and lower floors have Steel bushings that protrude at right angles and are coated with thermoplastic material.

Beim Zusammenbau der Böden werden in die Büchsen des einen Bodens Kupplungsstifte 21 eingesteckt, auf die dann die Büchsen des anderen Bodens aufgesteckt werden, nachdem zuvor die Berührungsflächen der thermoplastischen Ummantelung erwärmt worden sind. Anstelle der Kupplungsstifte 21 lassen sich auch Kupplungshülsen verwenden.When assembling the floors are in the bushes of one floor Coupling pins 21 inserted, onto which the bushings of the other bottom are then inserted be after previously the contact surfaces of the thermoplastic Sheathing have been heated. Instead of the coupling pins 21, coupling sleeves can also be used use.

Bei dem Ausführungsbeispiel nach den Fig. 5, 6 werden die Böden 1, 2 mit Hilfe von Schraubbolzen 30 verbunden, deren Enden mit ihren gegenläufigen Gewinden 31, 32 in mit den Böden 1, 2 verschweißten und ebenfalls gegenläufige Gewinde aufweisende Schraubbüchsen 33, 34 eingeschraubt werden. Um das Einschrauben der Bolzen 30 zu erleichtern, ist vorzugsweise ein Schraubgewinde länger als das andere, so daß beim Zusammenbau zunächst die Bolzen mit ihren längeren Schraubgewinden ein Stückchen in die Schraubbüchsen einer der beiden Böden eingeschraubt werden, ehe dann der andere Boden aufgesetzt und die Bolzen ganz in die einander gegenüberliegenden Schraubbüchsen eingeschraubt werden. Um etwaige Spalte zwischen den Stirnflächen der Schraubbolzen und den ihnen gegenüberliegenden Flächen der Schraubbüchsen zu vermeiden, können sich zwischen den Bolzen und den BUchsen elastische Scheiben befinden, oder das thermoplastische Material kann die Stirnflächen der Schraubbüchsen überdecken0 Um die Palette insgesamt mit thermoplastischem Material zu ummanteln und keine metallischen Oberflächen frei zu lassen, besitzen die Schraubbolzen in ihrem mittleren Teil vorzugsweise ebenfalls eine thermoplastische Ummantelung, beispielsweise aus Polyäthylen.In the embodiment according to FIGS. 5, 6, the floors 1, 2 connected by means of screw bolts 30, the ends of which with their opposite ends Threads 31, 32 in threads that are welded to the bases 1, 2 and also run in opposite directions having screw sleeves 33, 34 are screwed. To screw in the To facilitate bolt 30, one screw thread is preferably longer than the other, so that when assembling first the bolts with their longer screw threads Pieces are screwed into the screw sleeves of one of the two floors before then put the other bottom on and the bolts all the way into the opposing ones Screw sleeves are screwed in. Around any gaps between the end faces of the screw bolts and the opposite surfaces of the screw bushings avoid, there may be elastic washers between the bolts and the bushings, or the thermoplastic material can cover the end faces of the screw bushings0 To encase the pallet as a whole with thermoplastic material and not metallic To leave surfaces free, the screw bolts preferably have in their central part also a thermoplastic sheath, for example made of polyethylene.

Bei der Palette nach den Fig. 7, 8 weist der Unterboden 2 ebenfalls Schraubbüchsen auf, während an den Streben 3 mit thermoplastischem Material ummantelte Winkelstücke 41 mit Hilfe von Nieten 42 befestigt sind. Die Winkelstücke 41 besitzen Öffnungen 44, durch die Schraubbolzen 43 geführt sind, deren mit einem Gewinde versehene Enden in die Schraubbüchsen 40 eingeschraubt werden. Der richtige Abstand zwischen Ober- und Unterboden 1, 2 wird mit Hilfe von ebenfalls mit thermoplastischem Material ummantelten Abstandbüchsen 45 eingestellt. Um das Einsetzen und Einschrauben der Bolzen 43 zu erleichtern, weist die Tragfläche des Oberbodens eine Öffnung 46 auf, durch die ein Schraubenzieher oder ein Steckschlüssel zum Anziehen des Schraubbolzens eingeführt werden kann. Nach dem Einschrauben des Bolzens 43 wird das Loch 46 mit Hilfe eines elastischen Stopfens 47 verschlossen. Die über die Tragfläche des Oberbodens 1 hervorstehenden Stopfenkuppen wirken vorteilhafterweise wie ein Antirutschbelag.In the case of the pallet according to FIGS. 7, 8, the sub-floor 2 also has Screw sleeves on, while on the struts 3 sheathed with thermoplastic material Elbows 41 are fastened with the aid of rivets 42. The elbows 41 have Openings 44 through which Bolts 43 are guided, with which threaded ends are screwed into the screw sleeves 40. Of the correct distance between top and bottom 1, 2 is also made with the help of Spacer sleeves 45 sheathed with thermoplastic material are set. To that To facilitate insertion and screwing in of the bolts 43, the supporting surface of the The top has an opening 46 through which a screwdriver or a socket wrench can be inserted to tighten the screw bolt. After screwing in the Bolt 43, the hole 46 is closed with the aid of an elastic plug 47. The stopper tips protruding over the supporting surface of the top floor 1 act advantageously like an anti-slip covering.

Bei dem Ausführungsbeispiel nach Fig. 9 werden die Böden ebenfalls miteinander verschraubt. Dies geschieht jedoch mit Hilfe eines dem Schraubbolzen 30 gemäß Fig. 5, 6 ähnlichen Schraubbolzens 48, dessen eines mit einem Gewinde versehenes Ende jedoch durch eine Öffnung des Winkelstücks 41 greift und oberhalb mit einer Mutter 49 verschraubt ist.In the embodiment of FIG. 9, the floors are also screwed together. However, this is done with the help of a screw bolt 30 according to FIGS. 5, 6 similar screw bolt 48, one of which is provided with a thread However, the end engages through an opening of the elbow 41 and above with a Nut 49 is screwed.
