Description
Handgriff aus Isolierstoff für elektrische Handleuchter Handgriffe für elektrische Handleuchter, die in ihrem Innern die Fassung für die elektrische Glühlampe aufnehmen, werden wegen ihrer ungleichen Querschnittsformen und mit Rücksicht auf eine billige Fabrikation oft aus Isolierpreßstoff hergestellt. Die Isolierpreßstoffe sind aber im allgemeinen spröde. Da nun die elektrischen Handleuchter im wesentlichen in Werkstätten und anderen gewerblichen Betrieben verwendet werden, sind sie starken Beanspruchungen ausgesetzt, denen der Isolierpreßstoff nicht immer gewachsen ist; die Handleuchter zerbrechen deshalb leicht. Um die Bruchgefahr zu vermindern, hat man sie mit sehr großen Wandstärken ausgeführt. Dadurch werden die Handleuchter aber unhandlich und schwer.Handle made of insulating material for electric hand lamp handles for electric candlesticks, which inside the socket for the electric Incandescent light bulbs, because of their unequal cross-sectional shapes and with consideration Often made of molded insulating material for cheap fabrication. The insulating molded materials but are generally brittle. Since now the electric hand lamp essentially Used in workshops and other commercial operations, they are strong Exposed to stresses to which the insulating molded material is not always able to withstand; therefore, the candlesticks break easily. To reduce the risk of breakage, has you run them with very large wall thicknesses. This will make the candlesticks but unwieldy and heavy.
Nach der Erfindung bestehen die Handgriffe für elektrische Handleuchter aus einer rohrförmigen Einlage aus Isolierstoff von hoher Festigkeit und Elastizität, beispielsweise aus Hartpapier, um welche der den eigentlichen Handgriff bildende spröde Isolierpreßstoff herumgepreßt ist. Als Isollerpreßstoffe werden dabei vorzugsweise die sogenannten gummifreien Isolierstoffe verwendet.According to the invention, there are handles for electric hand lamps from a tubular insert made of insulating material of high strength and elasticity, for example made of hard paper, around which the actual handle forms brittle insulating material is pressed around. As Isollerpreßstoffe are preferred the so-called rubber-free insulating materials are used.
Auf der Zeichnung ist r der aus Isolierpreßstoff bestehende eigentliche Handgriff und 2 das in diesen eingelegte Rohr aus elastischem Isolierstoffe. 3 ist der zur Aufnahme der Glühlampenfassung bestimmte Innenraum des Handgriffes.In the drawing, r is the actual one made of molded insulating material Handle and 2 the inserted tube made of elastic insulating material. 3 is the interior of the handle designed to accommodate the bulb socket.
Die auf diese Weise hergestellten Handgriffe zeichnen sich durch große Festigkeit aus. Da der Isolierstoff fest auf der rohrförmigen Einlage aufliegt, so kann man ferner mit erheblich weniger Isolierpreßstoff auskommen, als wenn man den Handgriff ganz aus Isolierpreßstoff herstellen würde. Die Handgriffe werden infolgedessen leichter und handlicher.The handles made in this way are characterized by their large size Strength. Since the insulating material rests firmly on the tubular insert, so you can also get by with considerably less pressed insulating material than when you the handle would be made entirely of molded insulating material. The handles will be as a result, lighter and more manageable.
