"Unterlegscheibe""Washer"
Die Neuerung betrifft eine Unterlegscheibe für eine Befestigungsschraube zum Befestigen von emaillierten Blechen. Bei emaillierten Blechen bildet sich an den Lochrändern eine Emaille-Erhöhung. Wenn die Befestigungsschrauben mit einer ebenen Unterlegscheibe angeschraubt werden, so bilden sich an den Emaille-Erhöhungen und in dem Emaille-Überzug Risse.The innovation relates to a washer for a fastening screw for fastening enamelled sheets. In the case of enamelled sheets, it forms on the edges of the holes an enamel heightening. If the fastening screws are screwed on with a flat washer, so Cracks form on the enamel elevations and in the enamel coating.
Um diesen Nachteil zu vermeiden, ist es bekannt, die Unterlegscheiben aus Kunststoff herzustellen. Nachteilig dabei ist jedoch, daß diese Unterlegscheiben relativ teuer sind.In order to avoid this disadvantage, it is known that the washers made of plastic. The disadvantage here, however, is that these washers are relatively expensive.
Die Aufgabe der Neuerung ist, eine Unterlegscheibe für eine Befestigungsschraube zu offenbaren, bei der der Emaille-Überzug an den zu befestigenden Blechen nicht mehr beschädigt werden kann.The task of the innovation is to disclose a washer for a fastening screw in which the enamel coating can no longer be damaged on the sheets to be fastened.
Zu diesem Zweck ist die Erfindung dadurch gekennzeichnet, daß der äußere Rand der Unterlegscheibe als Auflagerand ausgebildet ist, während der Innenteil mit der Schraubenaufnahme-Bohrung mit einem Durchzug versehen ist. Weitere Merkmaie sind, daß die Schraubenaufnahme-Bohrung als konische Bohrung ausgebildet ist, oder daß die Schraubenaufnahme-itohrung auf einer topfförmigen Ausprägung angeordnet ist.For this purpose, the invention is characterized in that the outer edge of the washer acts as a support edge is formed, while the inner part is provided with the screw receiving bore with a passage. Further Features are that the screw receiving hole is designed as a conical hole, or that the screw receiving hole is arranged on a pot-shaped expression.
Zwei Ausführungsbeispiele der Erfindung sind in den Zeichnungen schematisch dargestellt. Es zeigen:Two exemplary embodiments of the invention are shown schematically in the drawings. Show it:
Fig. 1 eine Federscheibe mit einer konischen Schraubenaufnahme-Bohrung,1 shows a spring washer with a conical screw receiving bore,
Fig. 2 eine Federscheibe, bei der die Schraubenaufnahme-Bohrung auf einer topfförmigen Ausprägung angeordnet ist.Fig. 2 shows a spring washer in which the screw receiving bore on a cup-shaped Expression is arranged.
Nach Figur 1 besitzt die Unterlegscheibe 1 einen flachen Auflagerand 1' und eine konische Schraubenaufnahme-Bohrung 1" Bei der in Figur 2 gezeigten Unterlegscheibe 2 ist die Schraubenaufnahme-Bohrung 2" auf einer topfförmigen Ausprägung 2"' angeordnet.According to Figure 1, the washer 1 has a flat support edge 1 'and a conical screw receiving bore 1 " In the case of the washer 2 shown in FIG. 2, the screw receiving bore 2 ″ is on a pot-shaped expression 2 "'arranged.
Durch diese Maßnahmen wird erreicht, daß die Emaille-Erhöhungen 3 an den Lochrändern nicht belastet werden. Der Druck der Befestigungsschrauben 4 wird von den Auflagerändern I1 bzw. 2* der Befestigungsschrauben 4 sicher auf das Blech 3' übertragen. Der Emaille-Überzug wird nicht beschädigt.These measures ensure that the enamel elevations 3 are not stressed at the hole edges. The pressure of the fastening screws 4 is safely transferred from the support edges I 1 or 2 * of the fastening screws 4 to the sheet metal 3 '. The enamel coating is not damaged.
Der große Vorteil dieser Unterlegscheiben ist, daß durch sie Oberflächen-Beschädigungen sicher vermieden werden, und daß sie sehr preiswert sind.The great advantage of these washers is that they reliably prevent surface damage, and that they are very cheap.
