Description

HolzschraubeWood screw

Die Stellmacherei verwendet in großem Umfang Metallbautale gemeinsam mit solchen aus Holz, selten auch aus Kunststoff. Im besonderen werden landwirtschaftlxche Geräte wie Wagenkästen, aber auch Ackerbaugeräte aus Metall unter gemeinsamer Verwendung von Metallträgern und Holzbohlen oder -Planken hergestellt, überwiegend bestehen die Metallbauteile aus Eisen oder Stahl, aber auch aus Leichtmetall. Auch sind Verbundbauteile aus Aluminium und massivem Kunststoff in der Einführung begriffen. Besonders wenn diese Geräte'fahrbar sind, werden sie stärkeren Erschütterungen ausgesetzt. Entsprechendes gilt auch bei stehender Benutzung, z.B. für Dreschmaschinen, Stapler und ähnliche Geräte.The cartwright makes extensive use of metal structures together with those made of wood, rarely made of plastic. In particular, agricultural equipment such as car bodies, but also agricultural implements made of metal using metal girders and wooden planks or planks together, The metal components are predominantly made of iron or steel, but also of light metal. Also are composite components made of aluminum and solid plastic in the process of being introduced. Especially when these devices can be driven, they are exposed to stronger vibrations. The same also applies accordingly when used upright, e.g. for threshing machines, forklifts and similar devices.

Zur unlösbaren Verbindung massiver Verbundbaustoffe sind viele Schrauben notwendig, meist Holzschrauben, weil die unterschiedliche Dicke der Werkstoffe und auch die Art der praktischen Verwendung in vielen Fällen durch Muttern gesicherte Holzschrauben nicht zuläßt. Das sorgfältige Anziehen der vielen Schrauben bedeutet einen beachtlichen Aufwand an Handarbeit, besonders weil es auf den haltbaren Anzug jeder einzelnen Schraube im Sinne einer unlöslichen, also gesicherten Verbindung ankommt.There are many for the permanent connection of solid composite building materials Screws are necessary, mostly wood screws, because the different thicknesses of the materials and also the type of practical use are in many cases secured by nuts Does not allow wood screws. The careful tightening of the many screws means a considerable amount of manual work, especially because it depends on the durable tightening of every single screw in the sense of an insoluble, i.e. secured connection arrives.

Hier setzt das neue Muster ein. Es löst die Aufgabe, eine Holzschraube zu schaffen, die sehr einfach herstellbar ist, wie ein Nagel eingeschlagen werden kann und die eine unlösbare Verbindung zwischen Bauteilen aus verhältnismäßig dickem Metall und Holzbauteilen ergibt.This is where the new pattern comes in. It solves the task of being a To create a wood screw that is very easy to manufacture, that can be driven in like a nail and that is an unsolvable one Connection between components made of relatively thick metal and wooden components results.

Zur Lösung der gestellten Aufgabe besteht die neue Holzschraube, besonders zur unlöslichen Verbindung von Metall- und Holzbauteilen darin, daß der Schraubenschaft aus einem kantigen Stab gewendelt ist. Eine besonders einfache Gestaltung erhält das neue Arbeitsgerät dann, wenn der gewendelte Schaft einen quadratischen Querschnitt hat.To solve the problem, the new wood screw, especially for the permanent connection of metal and wooden components, consists in that the screw shaft consists of an angular rod is coiled. This is given a particularly simple design new tool when the coiled shaft has a square Has cross-section.

Die neue Holzschraube ist im übrigen endweise zugespitzt, mindestens zugescharft. Sie läßt sich zunächst ohne merkliche Schädigung der beim Wendeln auftretenden Kanten durch das Holz oder den Kunststoff hindurchschlagen. Beim Eintreffen in die Bohrung des Metallbauteile tritt dann eine stärkere Verformung der Wendelkanten unter entsprechender Verklemmung und Sicherung ein.The new wood screw is tapered at the end, at least sharpened. You can at first without any noticeable Damage to the edges occurring during coiling by knocking through the wood or plastic. Upon arrival in the When drilling the metal component, there is then a greater deformation of the helical edges with corresponding jamming and securing one.

Das neue Muster ist in der Zeichnung in einer beispielsweisen Ausführung dargestellt.The new pattern is in the drawing in an exemplary manner Execution shown.

Fig« 1 ist eine Seitenansicht der neuen Holzschraube, Fig« 2 und Fig. 1 is a side view of the new wood screw, Fig. 2 and

Fig. 3 sind dazugehörige Querschnitte, Fig. 3 are associated cross-sections,

Fig. 4 zeigt die Holzschraube im Längsschnitt in einer Benutzungsstellung. Fig. 4 shows the wood screw in a longitudinal section in a position of use.

Die Holzschraube 1 mit Kopf 2 undSchaft 3 ist mit der Wendelung versehen, die durch Verdrehung des ursprünglich kantigen Schaftes erzeugt ist. Der Schaft kann quadratischen Querschnitt 5 aufweisen, aber auch ungleichmäßigen Querschnitt 6. Er kann auch in anderer Weise kantig sein.The wood screw 1 with head 2 and shaft 3 is with the helix provided, which is generated by twisting the originally angular shaft. The shaft can have a square cross-section 5, but also uneven cross-section 6. It can also be in other Way to be edgy.

Die Holzsehraube 1 wird gemäß Fig. 4 wie ein Ifagel zunächst durch den weicheren Bauteil 7 - etwa eine Holzplanke oder -Bohle geschlagen, dann greift die Holzschraube in ein entsprechend vorgebohrtes Loch 9 des Metallträgers 8 ein« Man erkennt in Fig. 4 der praktischen Erfahrung entsprechend, daß die Wendel 4 beim Einschlagen in das Holz oder dergleichen praktisch nicht verformt werden. Eine starke mechanische Verformung und eine entsprechende Sicherung tritt jedoch beim Schlagen durch das Loch 9 des Metaiiträgers 8 ein, dann entsteht eine Verformung Io der Wendel 4.The Holzsehraube 1 is shown in FIG. 4 like an Ifagel first through the softer component 7 - for example a wooden plank or plank, the wood screw then engages in a correspondingly pre-drilled hole 9 in the metal support 8. This can be seen in FIG. 4 according to practical experience that the coil 4 when Impact in the wood or the like practically not deformed will. A strong mechanical deformation and a corresponding However, securing occurs when striking through the hole 9 of the metal carrier 8, then a deformation Io of the helix 4 occurs.
