Description

Bei der Herstellung von Möbelstücken, Versandkisten und anderem mehr liegt häufig die Aufgabe vor, zwei Teile so miteinander zu verbinden, daß die Verbindungsstelle unsichtbar bleibt und gegebenenfalls unzugänglich gemacht werden kann. Ein hierfür geeignetes Verbindungselement in Form einer Schraube ist gemäß der Erfindung so ausgebildet, daß der Schraubenschaft au beiden Enden Gewinde trägt, wovon das eine als Rechts-, das andere als Linksgewinde ausgebildet ist, und daß er in seiner Mitte als Schraubenkopf so gestaltet ist, daß die Schraube mit üblichen Werkzeugen befestigt oder gelöst werden kann.In the manufacture of furniture, shipping boxes, and more is often the task of connecting two parts together so that the connection point remains invisible and can be made inaccessible if necessary. One for this suitable connecting element in the form of a screw is according to the invention so designed that the screw shaft has threads on both ends, one of which as a right-hand thread, the other as a left-hand thread, and that it is in its center is designed as a screw head so that the screw is fastened with conventional tools or can be resolved.

Ein Ausführungsbeispiel der Erfindung ist im folgenden an Hand der Zeichnung beschrieben. Diese zeigt in Abb. i eine Ansicht einer Holzschraube gemäß der Erfindung, Abb.2 und 3 eine weitere Ausgestaltung der Schraube nach Abb. i, und Abb. 4 und 5 ein praktisches Anwendungsbeispiel für die Schraube, gemäß der Erfindung.An embodiment of the invention is shown below with reference to the Drawing described. This shows in Fig. I a view of a wood screw according to of the invention, Fig.2 and 3, a further embodiment of the screw according to Fig. i, and Figs. 4 and 5 show a practical example of application for the screw, according to FIG Invention.

Die neue Schraube, die als Doppelschraube bezeichnet werden kann, besitzt nach Abb. i zwei Schaftteile i und 2, die ein Rechts-, bzw. Linksgewinde tragen. In der Mitte ist der Schaft als Schraubenkopf, und zwar als Sechskantkopf 3 ausgebildet, hieran schließen sich die bei Holzschrauben üblichen gewindefreien Teile 4 und 5 an. In diese Teile können, wie die Abb. 2 und 3 zeigen, Längskerben 6 angebracht werden, die ein Verdrehen der Schraube und damit ein unerwünschtes Lockern der Verbindung verhindern. Die Abb. 3 zeigt einen Schnitt nach Linie III-III der Abb. 2.The new screw, which can be called a double screw, has two shaft parts i and 2, which have a right-hand and left-hand thread, as shown in Fig. i wear. In the middle is the shaft as a screw head, namely as a hexagonal head 3, this is followed by the thread-free standard with wood screws Parts 4 and 5. As Figs. 2 and 3 show, longitudinal notches can be made in these parts 6 are attached, twisting the screw and thus undesirable Prevent loosening of the connection. Fig. 3 shows a section along line III-III of Fig. 2.

Der in der Mitte liegende Kopf der Schraube kann auch jede andere Formgebung erhalten, z. B. Vierkantkopf oder Rundkopf mit durchgehenden Löchern, sofern nur ein Drehen der Schraube mit üblichen Werkzeugen ermöglicht ist.The head of the screw located in the middle can also be any other Get shape, z. B. square head or round head with through holes, provided that the screw can only be turned with conventional tools.

Die Abb. 4 und 5 zeigen die Verbindung einer Tischplatte 7 mit dem Untergestell B. Die Schraube ist hier in einer Aussparung g des Gestells 8 untergebracht. Sie ist von außen unsichtbar.Figs. 4 and 5 show the connection of a table top 7 with the Underframe B. The screw is housed in a recess g of the frame 8 here. It is invisible from the outside.

Die Abb. 5 zeigt einen Schnitt nach der Linie IV- IV der Abb. 4.Fig. 5 shows a section along the line IV-IV of Fig. 4.

PATENTANSPRÜCHE: i. Befestigungs- oder Verbindungsschraube, dadurch gekennzeichnet, daß der Schraubenschaft an beiden Enden Gewinde trägt, wovon das eine als Rechts-, das andere als Linksgewinde ausgebildet ist, und daß er in seiner Mitte als Schraubenkopf so gestaltet ist, daß die Schraube mit üblichen Werkzeugen befestigt oder gelöst werden kann. z. Befestigungs- oder Verbindungsschraube nach Anspruch i, dadurch gekennzeichnet, daß die an dem in der Mitte liegenden Schraubenkopf anschließenden gewindefreien Teile mit Längskerben ausgebildet sind, die eine Rückdrehung bzw. Lockerung der Schraube verhindern. PATENT CLAIMS: i. Fastening or connecting screw, characterized in that the screw shaft has threads at both ends, one of which is designed as a right-hand thread, the other as a left-hand thread, and that it is designed in its center as a screw head so that the screw is fastened with conventional tools or can be resolved. z. Fastening or connecting screw according to claim i, characterized in that the thread-free parts adjoining the screw head located in the center are designed with longitudinal notches which prevent the screw from turning back or loosening.
