Description

Lösbare Schraubenverbindung für eine Zarge oder einen Holm mit einer Platte, wie Rückenstützplatte, für Sitzmöbel Die Erfindung betrifft eine lösbare Schraubenverbindung für eine Zarge oder einen Holm mit einer Platte, wie Rückenstützplatte, wobei die Schraube mit ihrem Kopf im Holm und mit ihrem Schaft in einer parallel zur Plattenebene verlaufenden Bohrung der Platte, gegen Verdrehen gesichert, angeordnet ist, während die Schraubenmutter in einem quer zur Schraubenachse in der Platte vorgesehen, von außen zugänglichen Loch gelagert ist.Detachable screw connection for a frame or a stile with a Plate, such as back support plate, for seating furniture The invention relates to a detachable Screw connection for a frame or a stile with a plate, such as a back support plate, the screw with its head in the spar and with its shaft in a parallel to the plate plane running hole of the plate, secured against rotation, arranged is, while the screw nut in a transverse to the screw axis in the plate provided, is stored from the outside accessible hole.

Bekannt ist es, senkrecht aufeinanderstoßende Zargen mittels Schraube und Mutter zu verschrauben. Dabei ist die Mutter unzugänglich, während der Schraubenkopf von einem Werkzeug gedreht werden kann, welches senkrecht zur Schraubenachse angesetzt werden muß.It is known, vertically abutting frames by means of a screw and nut to screw. The nut is inaccessible, while the screw head can be rotated by a tool which is set perpendicular to the screw axis must become.

Ferner ist es bekanntgeworden, Platten mit Holmen in der Weise zu verschrauben, daß der Schraubenkopf am Holm dem Werkzeug offen zugänglich ist, während die Mutter in die Platte eingetrieben und von Werkzeugen nicht anfaßbar ist.It has also become known to use panels with spars in the manner screw that the screw head on the handlebar is openly accessible to the tool, while the nut is driven into the plate and cannot be touched by tools.

Demgegenüber ist beim Erfindungsgegenstand der Schraubenkopf holmseitig dem Schraubwerkzeug, z. B. Schraubenzieher, zugänglich angeordnet und die Mutter im Plattenloch gegen Verdrehen gesichert.In contrast, in the subject matter of the invention, the screw head is on the spar side the screwing tool, e.g. B. screwdriver, arranged accessible and the nut secured against twisting in the plate hole.

Diese Bauart ohne Verwenden vorstehender Verbindungselemente bietet die Vorteile, daß die Verschraubung rasch nachgestellt und auch leicht wieder gelöst werden kann, daß die Löcher für die Schraube und für die Mutter einfach herstellbar sind und daß die dem Werkzeug bequem zugängliche Verschraubung aus losen Teilen besteht, von denen keines mit Leim oder mittels Schlagwerkzeugen mit der Zarge oder mit dem Holm verbunden werden muß. Der Erfindungsgegenstand nützt die ganze Stärke der Stuhlbauteile dazu aus, die Verschraubung gegen ein Ausbrechen der Auflageflächen des Schraubenkopfes und der Mutter zu sichern.This type of construction without using protruding connecting elements offers the advantages that the screw is quickly readjusted and also easily loosened again can be that the holes for the screw and for the nut can be easily produced and that the screw connection, which is easily accessible to the tool, consists of loose parts exists, none of which with glue or using striking tools with the frame or must be connected to the spar. The subject of the invention uses all of its strength of the chair components to prevent the screw connection from breaking out of the screw head and the nut.

Das die Mutter aufnehmende Loch ist vorzugsweise ein Sackloch, da dieses eine Zusammenbauhilfe ist. Die in das Sackloch eingeführte Mutter hat die richtige Einschraubhöhe für das Gewinde der Schraube, so daß die Gewindeachsen der Mutter und der Schraube ungefähr gleichachsig verlaufen.The hole receiving the nut is preferably a blind hole, there this is an assembly aid. The mother inserted into the blind hole has the correct screw-in height for the thread of the screw so that the thread axes of the The nut and the screw are roughly coaxial.

In der Zeichnung ist ein Ausführungsbeispiel dargestellt. Es ist eine Rückenstützplatte mit einem Stuhlholm verschraubt, und zwar zeigt A b b. 1 eine Vorderansicht und A b b. 2 einen Querschnitt in Höhe der Achse A-A in A b b. 1.An exemplary embodiment is shown in the drawing. It is one Back support plate screwed to a chair spar, namely A b b. 1 one Front view and A b b. 2 shows a cross section at the level of the axis A-A in A b b. 1.

Die Schraube 1 erstreckt sich quer durch die Zarge 2 bzw. durch den Holm des Stuhles hindurch und führt mit ihrem Gewindeschaft 1 a in die Platte 3 hinein, wobei die Mutter 4 in einem Sackloch 7 der Platte 3 versenkt ist. Die eine Schraübenziehernute 9 äufweisende Mutter 4 ist ein im Loch 7 gegen Verdrehen gesicherter Zylinderbolzen, dessen Achse B die Schraubenachse A kreuzt. Auch der Kopf 1 b der Schraube 1 ist mit einer Schraubenziehernute 10 versehen. Der Kopf 1 b kann nach dem Verschrauben des Holmes 2 mit der Platte 3 dadurch unsichtbar gemacht werden, daß in das Loch im Holm 2 ein Abdeckbolzen 6 eingesetzt wird.The screw 1 extends transversely through the frame 2 or through the spar of the chair and leads with its threaded shaft 1 a into the plate 3 , the nut 4 being sunk in a blind hole 7 in the plate 3. The nut 4 having a screw puller groove 9 is a cylinder bolt secured against twisting in the hole 7 , the axis B of which crosses the screw axis A. The head 1 b of the screw 1 is also provided with a screwdriver groove 10 . The head 1b can be made invisible after the spar 2 has been screwed to the plate 3 by inserting a cover bolt 6 into the hole in the spar 2.

Sowohl die Dübel 5 als auch die stirnseitige Kehlung 8 der Platte 3 entsprechend dem Umfang der im Querschnitt kreisrunden Zarge 2 verstärken in üblicher Weise die durch die Verschraubung verursachte, durch den Reibungsschluß entstandene Verdrehsicherung der beiden Stuhlbauteile 2, 3. Both the dowels 5 and the frontal groove 8 of the plate 3 corresponding to the circumference of the frame 2, which is circular in cross section, reinforce in the usual way the anti-rotation lock of the two chair components 2, 3 caused by the screw connection and created by the frictional connection.
