Description
<Desc/Clms Page number 1>
Die Erfindung betrifft eine Sicherung für einen in einer Bohrung liegenden Bolzen gegen Verschiebung in seiner Achslängsrichtung durch eine Feder, welche in eine tangentiale Nut des Bolzens eingreift. Es ist bekannt, Bolzen durch Einschnappfedern zu sichern, damit sie nicht von selbst aus der Bohrung herausfallen und nicht dadurch die Verbindung ungewollt gelöst wird. Bei Scheren von Fenstern müssen die erforderlichen Scherenarme an dem Fensterrahmen befestigt werden, was durch eigene Schrauben, Nieten od. dgl. erfolgt. Dies ist nicht nur aufwendig und erfordert kompliziert gekrümmte Federn mit grosser Bruchgefahr, sondern die Federn liegen auch frei (an der Aussenseite der Scheren) und können daher auch Anlass zu Verletzungen geben.
Alle diese Nachteile werden erfindungsgemäss dadurch vermieden, dass zur Festlegung der Feder diese in einer zumindest teilweise verschlossenen Ausnehmung des den Bolzen aufnehmenden Körpers liegt.
Der Gegenstand der Erfindung ist in den Zeichnungen beispielsweise dargestellt. So zeigt Fig. 1 im Grundriss teilweise aufgeschnitten einen Scherenarm, wovon Fig. 2 einen Querschnitt veranschaulicht.
Wie man aus den Zeichnungen erkennen kann, besitzt ein aus Flachprofil hergestellter Scherenarm - an den Enden zwei Bohrungen --3-- zur Aufnahme der Gelenkbolzen--6--. Damit diese Gelenkbolzen --6-- in axialer Richtung festgelegt werden und damit nicht herausfallen können, besitzen sie Ringnuten --7--, in welche Federn --2-- beim Einschieben des Bolzens --6-- einschnappen, Diese Federn - sind als gebogene Drahtfedern ausgebildet und liegen in Ausnehmungen --4-- des Scherenarmes - -1--, welche sich zu beiden Seiten der Bohrungen --3-- befinden. Sie sind so angeordnet, dass sie die Bohrungen --3-- anschneiden und besitzen einen Doppel-T-förmigen Querschnitt, damit die Federn --2-nicht herausfallen können.
Diese Federn sind in die Ausnehmungen --4-- eingeschoben und verspreizen sich elastisch an den Wandungen. Sie besitzen ausserdem ein scharfkantiges Ende --5--, mit dem sie an der Wandung anliegen und durch zusätzliche Reibung gegen Längsverschiebung in den Ausnehmungen - gesichert sind. Die Federn --2-- liegen so zur Gänze in den Ausnehmungen --4--, sind von aussen kaum sichtbar, besitzen keine nach aussen vorstehenden scharfkantigen Enden, die eine Verletzungsgefahr darstellen können und zusätzliche Befestigungsmittel, wie Schrauben u. dgl. entfallen. Die Ausnehmungen --4-- können auch schwalbenschwanzförmigen Querschnitt aufweisen oder als Rohrkanal zur Gänze geschlossen sein.
Sie können einfach im Strangpressverfahren aus Aluminium gleichzeitig mit der Herstellung des Scherenarmprofils hergestellt werden, wobei jede zusätzliche Bearbeitung entfällt. Die Federn sind vorzugsweise als Drahtfedern in nichtrostendem Stahl ausgebildet, wodurch jede Korrosionsgefahr ausgeschaltet wird. Die Erfindung kann selbstverständlich bei jeder Art von Bolzensicherung auch ausserhalb von der Fensterfertigung angewendet werden.

The invention relates to a safeguard for a bolt lying in a bore against displacement in its axial longitudinal direction by a spring which engages in a tangential groove in the bolt. It is known to secure bolts with snap-in springs so that they do not fall out of the bore by themselves and the connection is not thereby unintentionally loosened. In the case of scissors for windows, the necessary scissor arms must be attached to the window frame, which is done using your own screws, rivets or the like. This is not only time-consuming and requires complicatedly curved springs with a high risk of breakage, but the springs are also exposed (on the outside of the scissors) and can therefore give rise to injuries.
All these disadvantages are avoided according to the invention in that, in order to fix the spring, it is located in an at least partially closed recess of the body that receives the bolt.
The object of the invention is shown in the drawings, for example. Thus, FIG. 1 shows a partially cut open plan view of a scissor arm, of which FIG. 2 illustrates a cross section.
As can be seen from the drawings, a scissor arm made of a flat profile has two bores at the ends --3-- for receiving the hinge pins - 6--. So that these hinge pins --6-- are fixed in the axial direction and thus cannot fall out, they have annular grooves --7-- into which springs --2-- snap when the bolt --6-- is inserted, these springs - are designed as curved wire springs and are located in recesses --4-- of the scissor arm - -1--, which are located on both sides of the bores --3--. They are arranged in such a way that they cut into the holes --3-- and have a double-T-shaped cross-section so that the springs --2- cannot fall out.
These springs are pushed into the recesses --4-- and expand elastically on the walls. They also have a sharp-edged end --5 - with which they rest against the wall and are secured against longitudinal displacement in the recesses by additional friction. The springs --2-- lie entirely in the recesses --4--, are barely visible from the outside, have no sharp-edged ends protruding outwards that could pose a risk of injury and additional fasteners such as screws and the like. the like. omitted. The recesses --4-- can also have a dovetail-shaped cross-section or be completely closed as a pipe channel.
They can simply be produced from aluminum using the extrusion process at the same time as the production of the scissor arm profile, with no additional processing required. The springs are preferably designed as wire springs made of stainless steel, whereby any risk of corrosion is eliminated. The invention can of course also be used for any type of bolt securing outside of window production.
