"Schraube""Screw"

Die Neuerung "betrifft eine Schraube mit unterhalb des Kopfes angeordneten«, in Längsrichtung des Schaftes ausgerichteten, keilförmigen Schneiden.The innovation "concerns a screw with below the head arranged ", aligned in the longitudinal direction of the shaft, wedge-shaped cutting edges.

Bekannte Schrauben dieser ixt dienen zum Einschlagen in Platten aus vergleichsweise weichem Material, so daß der Schraubenkopf in der Platte nicht mehr verdrehbar ist. Auf den Gewindeschaft können dann Befestigungsmuttern aufgedreht werden. Ein ähnliches Problem besteht bei der Befestigung von Möbelfüßen, Sesselfüßen oder dgl.. Auch hierbei muß eine Schraube mit vergleichsweise langem Schaft in dem langen Fuß möglichst unverdrehbar gehalten werden^ deren Gewinde schaft in ein Muttergewinde oder dgl. eingreift. Derartige Füße bestehen im allgemeinen aus Holz mit einer durchgehenden Bohrung für den Schraubensohaft. Die Schraube wird mit ihren Schneiden in den Holzfuß eingeschlagen. Dabei hat es sieh gezeigt, daß der Holzfuß beim Einschlagen springt· Die Schneiden reißen den Fuß auf. Known screws in this ixt are used to hammer into Plates made of comparatively soft material, so that the Screw head can no longer be rotated in the plate. on the threaded shaft can then be unscrewed fastening nuts will. A similar problem exists with the attachment of furniture feet, chair feet or the like. Here, too, one must Screw with a comparatively long shaft should be held in the long foot as non-rotatable as possible ^ their threaded shaft Engages in a nut thread or the like. Such feet are generally made of wood with a continuous Hole for the screw shaft. The screw is with their Cutting edges hammered into the wooden base. It has shown you that the wooden foot jumps when hammered in · The cutting edges tear the foot open.

Me !Teuerung bezweckt die Yermeidung dieses ITachteils und schlägt eine durch mehrere hintereinander angeordnete Schneiden mit abnehmender Pfeilhöhe der von dem Kopf entfernter gelegenen Schneiden gekennzeichnete Schraube vor.Me! Inflation aims to avoid this disadvantage and beats one by several cutting edges arranged one behind the other with decreasing arrow height of the one further away from the head located cutting edge marked screw.

Die zuerst in den Fuß eintretenden Schneiden mit kleiner Pfeilhöhe bewirken einen Torschnitt. Erst bei weiterem Einschlagen treten die weiteren Schneiden in den Fuß ein. Ein Ausreißen wird dadurch vollkommen vermieden. Dadurch daß man bei einer Schraube nach der !Teuerung eine viel größereThe cutting edges with a small arrow height that enter the foot first cause a gate cut. Only with further impact the other cutting edges enter the foot. This completely avoids tearing out. As a result of that one screw after the inflation a much larger one

Pläehe zur Aufnahme des beim Einschrauben des Pußes auftretenden Drehmomentes zur Verfügung hat, wird auch das Einschrauben erleichtert, insbesondere treten keine unzulässigen Belastungen auf.Plähe to take up the occurring when screwing in the foot Torque is available, screwing in is also made easier; in particular, there are no impermissible ones Loads on.

Eine neuerungsgemäße Schraube weist einen langen Schaft 1 mit einem Gewinde 2 sowie einem Zopf 3 auf. Diese Schraube wird in eine Längsbohrung eines angedeuteten Pußes 4 für Möbel, Sessel oder dgl. eingesetzt. Unterhalb des Kopfes 2 sind in Längsrichtung des Schaftes 1 ausgerichtete Schneiden 5 und 6 vorgesehen, welche jeweils eine scharfe Kante aufweisen und mittels eines geeigneten Bruekwerkzeuges aus dem Schraubenschaft herausgedrückt oder herausgepreßt sind. Die Schneiden 6 haben eine geringere Pfeilhöhe als die Schneiden 5. Man kann noch weitere Schneiden mit jeweils abnehmender Pfeilhöhe in Längsrichtung des Schaftes anordnen. Ebenso kann man in Umfangrichtung mehr als zwei Schneiden vorsehen. Im allgemeinen sind jedoch jeweils zwei zueinander diametral angeordnete Schneiden ausreichend.A screw according to the invention has a long shaft 1 with a thread 2 and a braid 3. This screw is in a longitudinal hole of an indicated foot 4 for Furniture, armchairs or the like. Used. Below the head 2 are cutting edges aligned in the longitudinal direction of the shaft 1 5 and 6 are provided, each having a sharp edge have and are pressed or squeezed out of the screw shaft by means of a suitable Bruek tool. The cutting edges 6 have a lower arrow height than the cutting edges 5. You can also use further cutting edges with each with decreasing arrow height in the longitudinal direction of the shaft. You can also have more than two cutting edges in the circumferential direction provide. In general, however, two cutting edges arranged diametrically to one another are sufficient.

Eine neuerungsgemäße Schraube wird in die Bohrung des betreffenden Pußes eingeschlagen, wobei sich die Schneiden 5 und 6 in das Holz einschneiden. Hierdurch ist die Schraube gegen Verdrehung inbezug auf den Puß gesichert. Die Schneiden mit kleinerer Pfeilhöhe 6 schneiden vors so daß sich die stärkeren Schneiden 5 leichter in das Holz einschneiden. Hierdurch wird ein Heißen oder Spalten des Holzes vermieden.A screw according to the innovation is hammered into the bore of the foot in question, with the cutting edges 5 and 6 cutting into the wood. In this way, the screw is secured against twisting in relation to the foot. The cutting edges with the smaller arrow height 6 cut in front of s so that the stronger cutting edges 5 cut more easily into the wood. This prevents the wood from heating up or splitting.
