Description
Vorrichtung zum lösbaren Festhalten zweier Bauteile aneinander Gegenstand der Erfindung ist eine Vorrichtung zum lösbaren Festhalten zweier Bauteile aneinander, welche einen Schraubbolzen und eine Mutter aufweist, gekenn zeichnet durch ein L-förmiges, steifes Blechpressstück, dessen einer Schenkel an seinem freien Ende minde stens eine unter spitzem Winkel aufgebogene Kralle und nahe beim anderen Schenkel eine Durchlassöffnung für den Schraubbolzen besitzt,
während dieser andere Schenkel bei seinem freien Ende mindestens eine auf einen Abschnitt der Wandung der Durchlassbohrung mindestens annähernd ausgerichtete Abstützfläche be sitzt.
Beiliegende Zeichnung stellt ein Ausführungsbei spiel des Erfindungsgegenstandes dar. Es zeigen: Fig. 1 einen Schnitt durch die Vorrichtung und zwei mit ihr aneinander festgehaltenen Bauteile, Fig. 2 einen der Fig. 1 ähnlichen Schnitt nur des zur Vorrichtung gehörenden Blechpressstückes, und Fig. 3 eine Draufsicht dieses letzteren.
Die Vorrichtung besteht aus dem steifen Stahlblech- pressstück 1, dem Schraubbolzen 2 und der von diesem getragenen Mutter 3. Als Beispiel von zwei durch die Vorrichtung lösbar aneinander festzuhaltenden Bautei len sind eine als Blechpressstück gefertigte Spültischab- deckung und eine Tragleiste B gezeigt, auf der sich die Abdeckung A abstützt. Der Schraubbolzen 2 ist im ge zeigten Beispiel durch Kondensator-Bolzenschweissung an der Unterseite der Abdeckung A befestigt.
Das den Hauptteil der Vorrichtung bildende Blech- pressstück 1 ist L-förmig, wobei die Schenkel la, 1b un gefähr gleich lang sind. Der Schenkel 1a hat einen U- förmigen Querschnitt; er besitzt nahe beim anderen Schenkel 1b eine Durchlassöffnung 4 für den Schraub bolzen 2 und der Querrand seines im spitzen Winkel aufgebogenen Endteiles 1c ist beim Stanzpressvorgang so zugeschnitten worden, dass mindestens eine Kralle 1d vorhanden ist. Der übergang zwischen den Schen keln 1a, 1b ist rund.
Der Schenkel 1b ist im Querschnitt etwa V-förmig, mit rundem übergang zwischen den Flanken, die nahtlos in den Steg und in die Flansche des Schenkels 1a übergehen. Der äussere Endteil 1e ist ein wärts abgekröpft; seine innenseitige Oberfläche 1f ist da zu bestimmt, flächenhaft an der glatten Mantelfläche des Schraubbolzens 2 anzuliegen, deshalb im mittleren Teil auf einen Abschnitt der Wandung der Durchlassöffnung 4 mindestens angenähert ausgerichtet.
Beim Anziehen der Mutter 3 gräbt sich die Spitze jeder Kralle 1d geringfügig in das Holz oder den son stigen Baustoff des Bauteiles B ein; dem ist zuzuschrei ben, dass obwohl das Blechpressstück 1 eigentlich einen Hebel bildet, auf den Schraubbolzen 2 kein nennens wertes Kipp- oder Biegemoment einwirkt, welches seine Befestigung am Bauteil A zusätzlich zur reinen Zugbe anspruchung beansprucht.
Device for releasably securing two components to one another The invention relates to a device for releasably securing two components to one another, which has a screw bolt and a nut, characterized by an L-shaped, rigid sheet metal pressing piece, one leg of which at its free end has at least one under claw bent up at an acute angle and a passage opening for the screw bolt close to the other leg,
while this other leg sits at its free end at least one on a portion of the wall of the passage bore at least approximately aligned support surface be.
The accompanying drawing shows an exemplary embodiment of the subject matter of the invention. They show: FIG. 1 a section through the device and two components held together with it, FIG. 2 a section similar to FIG. 1 only of the pressed sheet metal part belonging to the device, and FIG a plan view of the latter.
The device consists of the stiff sheet steel pressing piece 1, the screw bolt 2 and the nut 3 carried by this. As an example of two components to be releasably held together by the device, a sink unit cover made as a sheet metal pressing piece and a support strip B are shown on which the cover A is supported. The screw bolt 2 is attached to the underside of the cover A in the example shown by capacitor stud welding.
The sheet metal pressing piece 1, which forms the main part of the device, is L-shaped, the legs 1 a, 1 b being approximately the same length. The leg 1a has a U-shaped cross section; close to the other leg 1b, it has a passage opening 4 for the screw bolt 2 and the transverse edge of its end part 1c, which is bent up at an acute angle, has been cut to size during the stamping and pressing process so that at least one claw 1d is present. The transition between the legs 1a, 1b is round.
The leg 1b is approximately V-shaped in cross-section, with a round transition between the flanks, which merge seamlessly into the web and into the flanges of the leg 1a. The outer end part 1e is angled a downward; its inside surface 1f is intended to lie flat against the smooth lateral surface of the screw bolt 2, and therefore at least approximately aligned in the middle part with a section of the wall of the passage opening 4.
When tightening the nut 3, the tip of each claw 1d digs slightly into the wood or the other building material of component B; This can be attributed to the fact that although the pressed sheet metal piece 1 actually forms a lever, no significant tilting or bending moment acts on the screw bolt 2, which demands its attachment to component A in addition to the pure tensile stress.
