Description
Stehbolzen, insbesondere für Kühlschränke od. dgl. In der Technik wird manchmal die Aufgabe gestellt, zwei Flächen mit Abstand voneinander anzuordnen, wobei zur Bedingung gemacht wird, daß ein zwischen diesen beiden Flächen vorhandenes Wärmegefälle nicht zur Auswirkung kommt, d. h. also, daß die Temperatur der einen Fläche nicht auf die andere übertragen werden soll. Solche Fälle finden sich hauptsächlich im Kühlschrankbau, wo z. B. die Temperatur der Außenwandung des Kühlschranks möglichst nicht auf den inneren, als Nutzraum verwendeten Einsatzkasten nachteilig zur Auswirkung kommen soll.Stud bolts, in particular for refrigerators or the like. In technology is sometimes given the task of arranging two surfaces at a distance from each other, it being made a condition that there is one between these two surfaces Heat gradient does not have an effect, d. H. so that the temperature of the one Surface should not be transferred to the other. Such cases are mainly found in refrigerator construction, where z. B. the temperature of the outer wall of the refrigerator as possible does not have a detrimental effect on the inner insert box used as a usable space should come.
Die Erfindung betrifft einen Stehbolzen, insbesondere für Kühlschränke od. dgl., aus wärmedämmendem Werkstoff, bei dem die oben geschilderte Aufgabe in besonders einfacher und vorteilhafter Weise gelöst wird. Erfindungsgemäß ist der Stehbolzen mit einem dünnen aufgespritzten Metallüberzug versehen. Auf diese Weise erhält man einenStehbolzen, bei dem die Möglichkeit besteht, die beiden gegen Wärme voneinander zu isolierenden Gegenstände, zwischen denen der Stehbolzen angeordnet wird, miteinander elektrisch in leitende Verbindung, beispielsweise durch Löten, zu bringen, ohne daß dabei eine wirksame Wärmebrücke zwischen den beiden Gegenständen entsteht. Die dünn aufgespritzte Metallschicht ist nämlich in ihrem Querschnitt so klein, daß durch sie praktisch keine Wärme abgeleitet werden kann ; hingegen kann mit ihr ein ausreichender elektrischer Kontakt hergestellt werden. Stehbolzen nach der Erfindung sind insbesondere dann mit Vorteil anwendbar, wenn eine Erdung der zu bauenden Teile beabsichtigt ist. Der Bolzenkörper selbst wird zweckmäßig beiderseits als Befestigungsmittel, insbesondere als Schraube ausgebildet, oder er erhält eine solche Form, daß er eine Schraube aufnehmen kann. Der wärmedämmende Werkstoff des Stehbolzens kann z. B. ein Kunstharzpreßstoff oder aber ein anderer schlecht wärmeleitender Stoff, z. B. eine keramische Masse, wie Porzellan od. dgl., sein.The invention relates to a stud bolt, in particular for refrigerators Od. Like., Made of heat-insulating material, in which the above task in is solved in a particularly simple and advantageous manner. According to the invention is the Provide stud bolts with a thin sprayed-on metal coating. In this way you get a stud bolt with the possibility of protecting the two against heat objects to be isolated from one another, between which the stud bolts are arranged are electrically connected to each other, for example by soldering, without creating an effective thermal bridge between the two objects arises. The thinly sprayed-on metal layer is namely in its cross-section so small that it makes it practical no heat can be dissipated can ; however, sufficient electrical contact can be made with it will. Stud bolts according to the invention can be used with advantage in particular, if an earthing of the parts to be built is intended. The bolt body itself is expediently designed on both sides as a fastening means, in particular as a screw, or it is given a shape such that it can receive a screw. The heat insulating one Material of the stud can, for. B. a Kunstharzpreßstoff or another poorly thermally conductive material, e.g. B. a ceramic mass, such as porcelain or the like., be.
An sich ist es bekannt, Kunststoffpreßteile durch einen aufgespritzten Metallüberzug elektrisch leitend zu machen, um sie zur elektrischen Abschirmung, Erdung, für magnetische Feldeinwirkung, Röntgenstrahlenschutz od. dgl. zu benutzen. Es handelt sich dabei aber nicht um das Problem, zwei auf verschiedenem Temperaturniveau befindliche Blechwände mechanisch so miteinander zu verbinden, daß keine wesentliche Wärmebrücke entsteht.It is known per se, plastic molded parts by an injection-molded To make metal coating electrically conductive in order to use it for electrical shielding, Earthing, for magnetic field effects, X-ray protection or the like. To be used. But this is not about the problem, two at different temperature levels to connect existing sheet metal walls mechanically so that no essential Thermal bridge is created.
