Abstract

Plastics nail, injection-moulded from glass-fibre-reinforced polyamide, has tetragonal, esp. orthorhombic, cross-section, with its tip defined by a pyramid upon the rhombic shank. Its sides are concave. The joint of the shank to the head of the nail is grooved. The nail, is expensive to mfr., does not rust, and is esp. suitable for nailing asbestos sheets, e.g. for roofing, to joists and rafters. Its outstanding resistance to buckling on impact e.g. under hammer blows is advantageous.

Description

Nagel nail

Die Erfindung betrifft einen Nagel.The invention relates to a nail.

Den unterschiedlichen Verwendungszwecken eiitsprechend gibt es bereits sehr verschiedenartige Arten und Formen von Nägeln.According to the different uses there are already very different types and shapes of nails.

Die bekannten Nägel bestehen aus Metall, insbesondere Eisen oder Stahl.The known nails are made of metal, in particular iron or steel.

Die üblichen eisernen Nägel bestehen aus einem runden Schaft mit einem angestauchten bzw. angeformten, im weseiitlichen scheibenförmigen Kopf. In einem besonderen Arbeitsgang muß die Spitze des Nagels gebildet werden.The usual iron nails consist of a round shaft with a upset or molded, in the essential disk-shaped head. In one The tip of the nail must be formed in a special operation.

Abgesehen von dieser relativ umständlichen Herstellungsweise haben die bekannten eisernen Nägel vor allem den Nachteil, daß sie rosten. Insbesondere beim Anbringen von Fassadenplatten, z. B. Eterllit-Platten an den Außcnseiten vo Gebäuden, maclíen sich die relativ rasch rostenden Nagelköpfe unangenehm bemerkbar. Dies gilt aucli für die Vernagelung von Asbest-Dachplatten.Apart from this relatively cumbersome manufacturing process the main disadvantage of the well-known iron nails is that they rust. In particular when attaching facade panels, z. B. Eterllit plates to the Outside of buildings, the relatively quickly rusting nail heads make themselves uncomfortable noticeable. This also applies to the nailing of asbestos roof panels.

Demgegenüber liegt der Erfindung die Aufgabe zugrunde, einen billig herstellbaren, nicht rosteriden Nagel zu schaffen. Die Lösung dieser Aufgabe besteht gemäß der Erfindung im wesentlichen darin, daß der Nagel aus Kunststoff besteht. Vorzugsweise besteht der Nagel aus mit Glasfaser verstärktem Polyamid, ein solches Material ist z. B. unter der Typenbezeichnung A3EC7 erhältlich.In contrast, the invention is based on the object of a cheap to create manufacturable, non-rosterid nails. The solution to this problem is there according to the invention essentially in that the nail is made of plastic. The nail is preferably made of a polyamide reinforced with glass fiber Material is e.g. B. available under the type designation A3EC7.

Der Kunststoffnagel läßt sich im Spritzgußverfahren in großen Stückzahlen vergleichsweise billig herstellen. Die entsprechend kurzen Glasfasern sind dabei dem Granulat zugesetzt. Uberraschenderweise hat sich herausgestellt, daß der Kunststoffnagel die zum Nageln erforderliche Festigkeit, insbesondere Knickfestigkeit gegen die hammerschläge aufweist. Zu diesem Ergebnis dürfte stark beitragen, daß der Kunststoffnagel mit einer ziemlich scharfen Spitze hergestellt werden kann. Vorzugsweise hat der Nagel einen viereckigen, insbesondere rhombischen Querschnitt mit nach innen eingewölbten Seitenflächen. Die Spitze des Nagels ist durch eine Pyramide gebildet, welche auf diesem rhombischen, eingewölbten Querschnitt aufgesetzt ist. Der Schaft des Nagels weist also vier hohlschliffartige Schneiden auf, welche in der Spitze zusammentreffen. Dadurch schneidet sich der Nagel relativ leicht in das zu nagelnde holz ein. D,« eingewölbten Flächen zwischen de.l Schneiden sind rclativ druckentlastet, längs der Schneidet dagegen stellt sich ein Maximum an Flächenpressung ein. Insgesamt ist auf diese Weise der beim Einschlagen des Nagels auftretende Reibungswiderstand herabgesetzt.The plastic nail can be injection molded in large numbers produce comparatively cheaply. The correspondingly short glass fibers are included added to the granulate. Surprisingly, it turned out that the plastic nail the strength required for nailing, in particular resistance to buckling against the Has hammer blows. The plastic nail can be made with a fairly sharp point. Preferably the Nail a square, in particular rhombic, cross-section with inwardly vaulting Side faces. The tip of the nail is formed by a pyramid, which on is placed on this rhombic, arched cross-section. The shaft of the nail thus has four hollow-ground cutting edges which meet at the point. Through this the nail cuts into the wood to be nailed relatively easily. D, «vaulted Areas between the cutting edges are relieved of pressure along the cutting edge on the other hand, there is a maximum of surface pressure. Overall is on this Way, the frictional resistance occurring when hammering in the nail is reduced.

In der Zeichnung ist ein Ausführungsbeispiel dieses Kunststoffnagels dargestellt.In the drawing is an embodiment of this plastic nail shown.

Fig. 1 zeigt den Nagel in nsict und Fig. 2 im Querschnitt.Fig. 1 shows the nail in nsict and Fig. 2 in cross section.

Der Kopf 1 des Nagels ist im wesentlichen in Form einer konischen Scheibe ausgebildet. Uber llohlkehlen 2 geht der Kopf des Nagels in den Schaft 3 des Nagels über. Im Querschnitt ist der Nagel rhombisch, wobei die Seite@flächen 4 des lthombus nach innen eingewölbt sind. Dadurch werden vier relativ scharfe Schneiden gebildet. Dieser vorzugsweise schwach konische Schaft läuft an seinem Ende in einer scharfen, seiner Querschnittsform entsprechenden pyramidenförmigen Spitze G aus. Der Kunststoffnagel ist relativ gedrungen, scine Länge beträgt das Zehnfache seiner Dicke.The head 1 of the nail is essentially conical in shape Disc formed. The head of the nail goes into the shaft 3 via fillets 2 of the nail over. The cross-section of the nail is rhombic, with the side @ being flat 4 of the lthombus are vaulted inwards. This creates four relatively sharp cutting edges educated. This preferably slightly conical shaft runs at its end in a sharp pyramidal tip G corresponding to its cross-sectional shape. The plastic nail is relatively compact, its length is ten times its length Thickness.
