Description

Nach einer weiteren vorteilhaften Ausgestaltung sind die Schenkel des Federdrahtbügels spiralförmig gekrümmt.According to a further advantageous embodiment, the legs of the spring wire clip are spiral-shaped curved.

Eine andere Ausgestaltung der Erfindung ist dadurch gekennzeichnet, daß der Federdrahtbügel jeweils zwischen seinen befestigten Enden und seinen hakenförmigen Abwinklungen wellenförmig ausgebildet ist.Another embodiment of the invention is characterized in that the spring wire clip in each case between its fixed ends and its hook-shaped bends formed undulating is.

Schließlich ist es nach einer letzten Weiterbildung der Erfindung vorteilhaft, den Federdrahtbügel durch zwei oder mehrere sich vorzugsweise gegenüberliegende Krallen, die aus der Halteplatte herausgebogen sind, zu führen.Finally, according to a final development of the invention, it is advantageous to pass the spring wire clip two or more claws, preferably opposite one another, which are bent out of the holding plate are to lead.

Die Erfindung soll nachstehend an einem Ausführungsbeispiel näher erläutert werden. In der Zeichnung zeigt die Figur die perspektivische Darstellung einer Befestigungseinrichtung mit Federdrahtbügel ohne das Installationsgerät.The invention is to be explained in more detail below using an exemplary embodiment. In the drawing The figure shows the perspective view of a fastening device with a spring wire clip without the installation device.

Die Befestigungsvorrichtung für elektrische Installationsgeräte besteht aus der Halteplatte 2 und einem zwischen Halteplatte 2 und dem in der Zeichnung nicht dargestellten D-Sicherungssockel 6 angeordneten Federdrahtbügel 4. Die Halteplatte 2 ist mit gegenüberliegenden Abwinklungen 3 a, 3 b versehen, von denen eine (3 a) den nach außen abgewinkelten Rand la der U-förmigen Tragschiene 1 hakenförmig umgreift, während die andere (3 b) als Verdrehungsschutz dient. Zur Befestigung der Halteplatte 2 an dem D-Sicherungssockel durch Niete oder dergleichen Befestigungsmittel sind Bohrungen 9 vorgesehen. In bekannter Weise umgreift der als federndes Rastorgan wirkende Federdrahtbügel 4 den nach außen abgewinkelten Rand 1 b der Tragschiene 1 gegenüber der Abwinklung 3 α der Halteplatte 2 durch die Krümmung 4 a zunächst hakenförmig und ist dann mit Auflaufschrägen 4 α für ein federndes Einschnappen von der Tragschiene 1 weggebogen. Die langgestreckten Schenkel 4 b des Federdrahtbügels 4 sind U-förmig gekrümmt und rechtwinklig abgebogene Enden in Bohrungen 5 der Halteplatte 7 festgelegt. The fastening device for electrical installation devices consisting of the retaining plate 2 and between the holding plate 2 and in the drawing, not shown, D-fuse base 6 disposed spring wire brackets 4. The support plate 2 is provided with opposed angled portions 3 a, provided b 3, one of which (3 a ) the outwardly angled edge la of the U-shaped support rail 1 engages in a hook shape, while the other (3 b) serves as a protection against rotation. Bores 9 are provided for fastening the retaining plate 2 to the D fuse base by means of rivets or similar fastening means. In a known manner, the spring wire bracket 4, acting as a resilient latching element, engages around the outwardly angled edge 1 b of the mounting rail 1 with respect to the bend 3 α of the holding plate 2 through the curvature 4 a, initially in the shape of a hook and is then provided with bevels 4 α for a resilient snap-in from the mounting rail 1 bent away. The elongated legs 4 b of the spring wire clip 4 are curved in a U-shape and ends bent at right angles are fixed in bores 5 of the holding plate 7.

Beim Lösen der Befestigungsvorrichtung mittels eines Werkzeuges, z. B. eines Schraubenziehers, das zwischen den Auf lauf schrägen 4 α und dem diese verbindenden Steg Ad angesetzt und mit dessen Hilfe der Federdrahtbügel 4 von der Tragschiene 1 weggedrückt wird, ist eine Federung nicht nur im Bereich der hakenförmigen Krümmung 4 c, sondern auch an den gekrümmten Schenkeln 4 & des Federdrahtbügels 4 und damit in seiner Bewegungsrichtung gegeben. Die Größe der Federkraft und der Federweg stehen in direkter Abhängigkeit von Länge und Art der Biegung der Federdrahtbügelschenkel 4 b und lassen sich damit auf die jeweils gewünschten Verhältnisse beliebig einstellen.When loosening the fastening device by means of a tool, e.g. B. a screwdriver that is set between the inclined 4 α and the connecting web Ad and with the help of which the spring wire bracket 4 is pushed away from the mounting rail 1, a suspension is not only in the area of the hook-shaped curvature 4 c, but also on the curved legs 4 & of the spring wire clip 4 and thus given in its direction of movement. The magnitude of the spring force and the spring deflection are directly dependent on the length and type of bend in the spring wire bracket legs 4 b and can thus be set as desired to the desired proportions.

Um die Befestigung des Federdrahtbügels 4 von der Beschaffenheit des Gerätesockelbodens und dem Abstand zwischen diesem und der Halteplatte 2 unabhängig zu machen, sind aus der Halteplatte 2 zwei sich gegenüberliegende Krallen 8 herausgebogen, die den Federdrahtbügel 4 zwischen sich und der Halteplatte 2 führen.To the attachment of the spring wire bracket 4 of the nature of the base of the device and the To make the distance between this and the holding plate 2 independent, the holding plate 2 is two opposing claws 8 bent out, which the spring wire clip 4 between them and the retaining plate 2 lead.
