Description
Druckknopf mit Schale, zur Betätigung von Schaltkontakten ZurBetätigung von Druckkontakten, welche hinter Türen montiert sind, werden Druckknöpfe verwen det, die in passenden, in Löchern der Türe befestigten Schalen gelagert sind und ein Betätigen der Kontakte von aussen ermöglichen.
Um in der Tiefe nicht viel Platz zu verlieren, sol len solche Druckknöpfe möglichst kurz sein. Die vor liegende Erfindung ermöglicht, Druckknöpfe mit Schalen zu bauen mit einer im Vergleich zum Weg des Druckknopfes minimalen Länge und trotzdem eine sichere Führung des Knopfes zu erreichen, wel che Verkanten und Verklemmen verhindert.
Der erfindungsgemässe Druckknopf zeichnet sich aus durch mindestens drei an der Schale befestigte Führungsstücke für den Knopf, welche radial nach innen gerichtet sind, parallel zur Druckknopfachse stehen und am Druckknopf in ebenfalls zur Achse parallele Schlitze eingreifen.
In der beiliegenden Zeichnung ist ein Ausfüh rungsbeispiel eines solche Druckknopfes in Fig. 1 im Schnitt längs der Achse und in Fig. 2 im Schnitt quer zur Achse dargestellt.
Die Druckknopfschale 4 ist mit dem Anpressring 2 mittels mehrerer Schrauben 1 in einem Loch der Türe 3 befestigt. An der Schale 4 ist der gestanzte Ring 8 befestigt, mit vier radial nach innen gerichte ten und um 90,1 abgedrehten Führungsstücken 12. Diese Führungsstücke sind in Richtung der Achse 6 mindestens dreimal länger als die Breite der in Fig. 2 sichtbaren Schlitze zwischen je zwei der vier pris matischen Verlängerungen 13 des Druckknopfes 12.
Um die Verlängerungen 13 gegenseitig zu verstei fen und festzuhalten, ist auf das Ende ein im wesent lichen ringförmiger Teil 9 aufgesteckt, welcher zu gleich als Anschlag des Kopfes 5 dient, damit dieser nicht infolge der Kraft der Feder 7 aus der Schale 4 vorne herausgedrückt wird. Zwischen die Verlänge rungen 13 ist der zylindrische Teil 10 eingeschoben, welcher am Ende tellerförmig vergrössert ist und die auf den Druckknopf 5 vorne ausgeübte Kraft auf den in der Zeichnung nicht dargestellten Schalterkontakt überträgt.
Push button with shell, for actuating switch contacts To actuate pressure contacts that are mounted behind doors, push buttons are used that are stored in matching shells fixed in holes in the door and enable the contacts to be actuated from outside.
In order not to lose a lot of space in the depth, such push buttons should be as short as possible. The present invention makes it possible to build push buttons with shells with a minimal length compared to the path of the push button and still achieve secure guidance of the button, which prevents tilting and jamming.
The push button according to the invention is characterized by at least three guide pieces for the button attached to the shell, which are directed radially inward, are parallel to the push button axis and engage on the push button in slots that are also parallel to the axis.
In the accompanying drawing, an exemplary embodiment of such a push button is shown in Fig. 1 in section along the axis and in Fig. 2 in section transverse to the axis.
The push button shell 4 is fastened to the pressing ring 2 by means of several screws 1 in a hole in the door 3. On the shell 4, the punched ring 8 is attached, with four radially inwardly directed and rotated by 90.1 guide pieces 12. These guide pieces are in the direction of the axis 6 at least three times longer than the width of the visible in Fig. 2 slots between each two of the four prismatic extensions 13 of the push button 12.
In order to mutually stiffen and hold the extensions 13, an essentially union ring-shaped part 9 is attached to the end, which also serves as a stop of the head 5 so that it is not pushed out of the shell 4 at the front due to the force of the spring 7 . Between the extension stanchions 13, the cylindrical part 10 is inserted, which is enlarged at the end plate-shaped and the force exerted on the push button 5 at the front transfers to the switch contact, not shown in the drawing.
