Knieschonerknee pad
Die Erfindung betrifft einen Knieschoner zum Schutz der Kniegelenke z.B. bei handwerklichen Arbeiten aus einer durchbrochenen thermoplastischen Außenschale und einem weichen, flexiblen geschäumten Innenteil, das teilweise durch die Durchbrüche der Außenschale hindurchtritt.The invention relates to a knee pad for protecting the knee joints, e.g. during manual work, consisting of a perforated thermoplastic outer shell and a soft, flexible foamed inner part which partially penetrates through the perforations of the outer shell.
Knieschoner aus einer thermoplastischen Außenschale und geschäumtem Innenteil sind bekannt, siehe Gebrauchtmuster 299 03 761.4 .Knee pads made of a thermoplastic outer shell and a foamed inner part are known, see used model 299 03 761.4 .
Werden Außenschalen aus harten, steifen Thermoplasten verwendet, so neigt der Knieschoner bei Verwendung zum Rutschen, insbesondere bei nassen und glatten Böden.If outer shells made of hard, rigid thermoplastics are used, the knee pad tends to slip during use, especially on wet and slippery floors.
Der Erfindung liegt daher die Aufgabe zugrunde, einen Knieschoner darzustellen aus einer thermoplastischen Außenschale und geschäumtem Innenteil. Dabei soll die Rutschfestigkeit der Außenschale verbessert werden, ohne das Fertigungsverfahren grundlegend zu verändern oder zusätzliche Fertigungsschritte einzuführen.The invention is therefore based on the object of providing a knee pad made of a thermoplastic outer shell and a foamed inner part. The slip resistance of the outer shell is to be improved without fundamentally changing the manufacturing process or introducing additional manufacturing steps.
Das wird erfindungsgemäß durch einen Knieschoner gelöst aus einer thermoplastischen Außenschale und einem geschäumten Innenteil, bei dem die Außenschale Durchbrüche enthält, durch die der Schaum des Innenteils nach außen hindurchtritt.This is achieved according to the invention by a knee pad consisting of a thermoplastic outer shell and a foamed inner part, in which the outer shell contains openings through which the foam of the inner part passes to the outside.
Mit dem erfindungsgemäßen Knieschoner wird folgendes erreicht:The knee pad according to the invention achieves the following:
-Der nach außen durchtretende weiche und flexible Schaum erhöht die Rutschfestigkeit des Knieschoners ganz wesentlich.-The soft and flexible foam that penetrates to the outside significantly increases the slip resistance of the knee pad.
-Die Durchbrüche der Außenschale können beim thermoplastischen Spritzguß mit erzeugt werden, so daß kein zusätzlicher Arbeitsschritt nötig ist.-The openings in the outer shell can be created during thermoplastic injection molding, so that no additional work step is necessary.
-Der flexible, weiche Schaum tritt beim Ausschäumen der Außenschale zwangsweise durch die Durchbrüche, so daß auch hierbei kein Zusätzlicher Arbeitschritt erforderlich-The flexible, soft foam passes through the openings when the outer shell is foamed, so that no additional work step is required
Ein Ausführungsbeispiel des erfindungsgemäßen Knieschoners wird anhand der Zeichnung erläutert. Es zeigen:An embodiment of the knee pad according to the invention is explained using the drawing. Shown are:
Fig.1: Knieschoner, Draufsicht von unten, Thermoplastschale mit durchgeschäumtem PolyurethanFig.1: Knee pads, top view from below, thermoplastic shell with foamed polyurethane
1 = thermoplastische Außenschale1 = thermoplastic outer shell
2 = Polyurethanschaum2 = Polyurethane foam
Fig.2: Knieschoner, Schnitt A/BFig.2: Knee pads, section A/B

2 = Polyurethanschaum2 = Polyurethane foam
Fig.3: Knieschoner, Schnitt C/DFig.3: Knee pads, section C/D
1 = thermoplastische Außenschale1 = thermoplastic outer shell
2 = Polyurethanschaum2 = Polyurethane foam
Der in Fig. 1-3 gezeigte erfindungsgemäße Knieschoner ist beispielhaft.The knee pad according to the invention shown in Fig. 1-3 is exemplary.
Vorzugsweise besteht die thermoplastische Außenschale aus Polyolefin, ABS oder Polyamid. Vorteilhaft ist auch die Verwendung von thermoplastischem Polyurethan (TPU) für den Fall, daß auch der weiche Schaumstoff Polyurethan ist. Auf diese Weise wird eine einheitliche Stoffklasse für die Entsorgung erhalten.The thermoplastic outer shell is preferably made of polyolefin, ABS or polyamide. It is also advantageous to use thermoplastic polyurethane (TPU) if the soft foam is also polyurethane. This ensures a uniform material class for disposal.
Der weiche Schaumstoff besteht vorzugsweise aus formgeschäumten Polyurethan, sogenanntem Polyurethan Weichschaum. Dieser Weichschaum wird vorzugsweise in die vorgeformte thermoplastische Außenschale im Reaktionsgießverfahren hineingeschäumt.The soft foam preferably consists of molded polyurethane, so-called polyurethane soft foam. This soft foam is preferably foamed into the preformed thermoplastic outer shell using the reaction molding process.
Andere Möglichkeiten sind jedoch auch die Verwendung von Polyolefinschaum oder Ethylenvinylacetatschaum.However, other options include the use of polyolefin foam or ethylene vinyl acetate foam.
