Stativklemme
BeschreibungTripod clamp
Description
Die Erfindung betrifft eine Stativklemme zum Befestigen von Glasapparaturen an Laborstativen, bestehend aus zwei gelenkig miteinander verbundenen Bügeln, die an ihrem freien Ende mit Klemmbacken versehen und mittels einer Spannschraube um die Gelenkachse zueinander bewegbar sind, wobei die Klemmbacken an der Auflageseite eine elastische Einlage aufweisen. 10The invention relates to a stand clamp for fastening glass apparatus to laboratory stands, consisting of two brackets connected to one another in an articulated manner, which are provided with clamping jaws at their free end and can be moved towards one another around the joint axis by means of a clamping screw, whereby the clamping jaws have an elastic insert on the support side. 10
Bisher war es üblich, Stativklemmen an der die fest7.«hsTten<ii« Glasapparatyr U!P,i»3SS<ümcsr. Seit« der Klemmbacken isit einer Xorkeini^q» zu versehen. Unter der Einwirkung von Wärme oder Flüssigkeiten lösen sich solche Einlagen jedoch leicht sb. Es wurde auch schon versucht, die Klemmbacke mit Kunststoff, beispielsweise PVC, zn beschichten. In der praktischen ig hat sich diese BeEs-Uhtwrv* jedoch aii zu hart und thermisch belastbar erwiesen.Until now it was usual to attach tripod clamps to the glass apparatus. The clamping jaws are provided with a non-slip surface. However, such inserts easily come loose under the influence of heat or liquids. Attempts have also been made to coat the clamping jaws with plastic, for example PVC. In practice, however, this type of coating has proved to be too hard and thermally resilient.
Demgemäß Eiland die Aufgabe, eine Statt&ngr;klemme zu entwickeln, bei der die Beschichtung der Klessnbacken sowohl d;t ä ; derungen an ein elastisches Einspannen einer Glasapparatur als auch an eine thermisch höhere Belastbarkeit al? bei den bekannten Werkstoffen erfüllt.Accordingly, Eiland was tasked with developing a clamp in which the coating of the clamp jaws fulfilled both the requirements for elastic clamping of a glass apparatus and for a higher thermal load capacity than with the known materials.
Die Aufgabe wurde durch eine Stativklemme der eingangs geschilderten Art gelöst, bei der die elastische Einlage durch eine Besbichtung aus S.li -nkautschuk gebildet ist.The task was solved by a tripod clamp of the type described above, in which the elastic insert is formed by a coating of silicone rubber.
Nachfolgend ist ein in der Zeichnung schematisch dargestelltes Ausführungsbeispiel der erfindungsgemäß-n Stativklemme beschrieben.An embodiment of the tripod clamp according to the invention is described below, shown schematically in the drawing.
Stativklemmen zum Befestigen von Glasapparaturen an Laborstativen werden in verschiedenen Formen und Größen hergestellt. Beim vorliegenden Ausführungsbeispiel sind in an sich bekannter weise zwei Bügel 1 und 2 durch eine Achse 3 gelenkig miteinander verbunden, wobei der eine Bügel 1 mit einem Linksgewinde 4 und der anderen Bügel 2 mit einem Rechtsgewinde 5 versehen ist. Dadruch sind die beiden Bügel mittels einer in den Gewinden geführten Spannschraube 6 zueinander bewegbar.Tripod clamps for attaching glass apparatus to laboratory stands are manufactured in various shapes and sizes. In the present embodiment, two brackets 1 and 2 are connected to one another in a manner known per se by an axis 3, with one bracket 1 being provided with a left-hand thread 4 and the other bracket 2 with a right-hand thread 5. The two brackets can therefore be moved relative to one another by means of a clamping screw 6 guided in the threads.
Die Bewegbarkeit kann auch durch einen in einer Bohrung des einen Bügels gehaltenen und durch eine Bohrung des anderen Bügels lose hindurchtretenden Gewindestift erreicht werden. Mit Hilfe einer auf dem nach außen überstehenden Teil des Gewindestifts geführten Flügelmutter sind die Bügel gegen eine Feder zueinander bewegbar.The mobility can also be achieved by a threaded pin held in a hole in one bracket and passing loosely through a hole in the other bracket. With the help of a wing nut on the outwardly protruding part of the threaded pin, the brackets can be moved towards each other against a spring.

An einem der beiden Bügel ist ein Stab 7 zum Sefestigen der Stativklemme an einem Laborstativ angebracht.A rod 7 is attached to one of the two brackets for securing the tripod clamp to a laboratory tripod.
Die Bügel 1 und 2 sind zum Festhalten einer Slasapparatur 8 an ihrem freien Ende mit Klemmbacken 9 versehen, deren die Apparatur einspannenden Flächen eine elastische Beschichtung 10 aus Siliconkautschuk aufweisen. Diese Beschichtung erlaubt einen Einsatz der Stativklemme bis mindestens + 25O0C.The brackets 1 and 2 are provided with clamping jaws 9 at their free end for holding a laser apparatus 8, the surfaces of which clamp the apparatus have an elastic coating 10 made of silicone rubber. This coating allows the stand clamp to be used up to at least + 25O 0 C.
