Description

Gegenstand der Erfindung ist eine Schraube, deren Neuheit darin besteht, daß die Gewindegänge nach Art einer Förderschnecke gestaltet sind, so daß die Schraube in den Erdboden hauptsächlich und in beliebiger Weise eingeschraubt werden kann, um mit ihrem herausragenden Ende als Befestigungsmittel für irgendwelche Zwecke zu dienen, sei es, daß Zeltbahnen, Balken o. dgl., oder sei es,The invention relates to a screw, the novelty of which is that the threads are designed in the manner of a screw conveyor, so that the screw in the ground mainly and can be screwed in in any way, with its protruding end as a fastening means to serve for any purpose, be it that tent sheets, beams or the like, or be it,

ίο daß frei weidende Tiere an die Schraube angekuppelt werden. Zweckmäßig ist sie so eingerichtet, daß die einzelnen Gänge aus entsprechend gebogenen und gestanzten Blechplatten, die zudem noch des besseren Haltes wegen gewellt sind, bestehen, wobei diese Platten an einem röhrenförmigen Körper gehalten, und dieser selbst an seinem oberen Ende zur Aufnahme der Anschlußmittel für den zu befestigenden Gegenstand ausgestaltet ist.ίο that free grazing animals are coupled to the screw will. It is expediently set up so that the individual courses from accordingly bent and stamped sheet metal plates, which are also corrugated for better hold, exist, these Plates held on a tubular body, and this itself on its upper End designed to receive the connecting means for the object to be fastened is.

Die Zeichnung veranschaulicht den Erfindungsgegenstand in Fig. ι in Ansicht, in Fig. 2 teilweise im Schnitt.The drawing illustrates the subject matter of the invention in FIG Fig. 2 partially in section.

Gemäß der Erfindung besteht die neue Schraube nach dem vorliegenden Ausfuhrungsbeispiel aus einer zweckmäßig konischen Metallröhre a, die einen beliebigen Querschnitt aufweisen kann, vorteilhaft jedoch rund gehalten ist. h sind die einzelnen Gewindegänge, die wie bei einer Förderschnecke geformt sind, und im Ausführungsbeispiel aus einem einheitlichen gewundenen Blechstreifen bestehen oder aber aus einzelnen Blechstreifen zusammengesetzt sein können. Im letzteren Falle, der auch im Beispiel dargestellt ist, sind winkelförmige Streifen gewählt, deren wagerechte Schenkel b1 den eigentlichen Gang bilden, während der senkrechte Schenkel, als Hülse c ausgebildet, den Hohlkern a umschließt. Durch den äußeren Ring d, die innere Einsatzröhre und die in diese eingesetzte Verstärkungsmuffe f ist eine Verbindung dieser genannten Teile mit dem oberen Gewinderinge durch eine Schraube g geschaffen. According to the invention, the new screw according to the present exemplary embodiment consists of an expediently conical metal tube a, which can have any cross-section, but is advantageously kept round. h are the individual threads, which are shaped like a screw conveyor and, in the exemplary embodiment, consist of a uniform, wound sheet-metal strip or can be composed of individual sheet-metal strips. In the latter case, which is also shown in the example, angular strips are selected, the horizontal legs b 1 of which form the actual passage, while the vertical leg, designed as a sleeve c , encloses the hollow core a. By means of the outer ring d, the inner insert tube and the reinforcing sleeve f inserted into it, a connection of these mentioned parts with the upper threaded ring is created by a screw g.

Eine derartige Schraube kann ohne weiteres in den Erdboden eingeschraubt werden, wobei die breitflächigen Gewindegänge Gewähr für einen festen Sitz der Schraube leisten, der noch dadurch gefördert werden kann, daß die Gewindegänge wellenförmig gestaltet sind. Der obere Teil der Verstärkungsmuffe f dient, wie ohne weiteres ersichtlich, zum Aufsetzen einer Röhre e, die auch Gewindegänge aufnehmen oder aber unmittelbar zur Befestigung des betreffenden Gegenstandes, sei es nun ein Zelt, ein Balken oder sonst etwas, dienen kann.Such a screw can easily be screwed into the ground, the wide threads guaranteeing a tight fit of the screw, which can be further promoted by the fact that the threads are designed to be undulating. The upper part of the reinforcing sleeve f is used, as can be readily seen, to put on a tube e, which can also accommodate threads or directly to attach the object in question, be it a tent, a beam or something else.

Eine derartige Schraube würde sich auch vorteilhaft einbetonieren lassen, wenn es sich darum handelt, eine vorläufige Befestigungsart in eine dauernde umzuwandeln.Such a screw would also be advantageously concreted in if it were It is a matter of transforming a temporary method of attachment into a permanent one.
