Description
KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Mit der Befestigungsvorrichtung für elektrische Apparate nach Patent 306606 wird die größte Reichfläche des Apparatebefestigungsbolzens erzielt, wenn das Schienenpaar auf seiner Unterlage so befestigt wird, daß die Mittellinie der übereinandergelegten Schienen die kurze, und die Mittelsenkrechte dazu die lange Achse einer durch Kreisbögen begrenzten Fläche ergibt. Um diese günstigste Be- festigung zu gewährleisten, soll nicht die bisher bei ähnlichen Befestigungsvorrichtungen übliche Befestigung mittels Schrauben und einzelner in oder unterhalb der Unterlage angebrachter Gewindemuttern vorgesehen werden, zumal letztere die Nachteile besitzen, daß sie leicht verlorengehen und für mehrere Befestigungslagen der Vorrichtung mehrfach vorzusehen sind, sondern es soll gemäß vorliegender Erfindung jedes Schienenpaar mit einem Befestigungsblech k (Fig. 1 und 2) versehen werden, welches die erforderlichen Gewindelöcher im Abstande der kurzen Achse der Reichfläche besitzt. Dieses Blech k wird entweder oberhalb der'Unterlage (Fig. 1) oder unterhalb einer solchen (Fig. 2) angeordnet und kann als Lehrstück für den Abstand der in.einer Unterlagplatte anzubringenden Durchgangslöcher für die Befestigungsschrauben c, c' benutzt werden.With the fastening device for electrical apparatus according to patent 306606, the largest area of reach of the apparatus fastening bolt is achieved if the pair of rails is fastened to its base in such a way that the center line of the superimposed rails results in the short axis and the center perpendicular to it the long axis of an area delimited by circular arcs. In order to ensure this most favorable fastening, the fastening by means of screws and individual threaded nuts attached in or below the base, which has been common with similar fastening devices, should not be provided, especially since the latter have the disadvantages that they are easily lost and must be provided several times for several fastening positions of the device instead, according to the present invention, each pair of rails is to be provided with a fastening plate k (FIGS. 1 and 2) which has the necessary threaded holes at a distance from the short axis of the reach area. This sheet k is arranged either above the base (Fig. 1) or below such (Fig. 2) and can be used as a teaching piece for the spacing of the through holes to be made in a base plate for the fastening screws c, c ' .
