Description
Fuss-Schalter für Kleinmotoren. Den Gegenstand vorliegender Erfindung bildet ein Fussschalter für Kleinmotoren, bei welchem in einem schalenartigen Gehäuse eine unter Federwirkung stehende und mit dem Fuss zu betätigende Stromschliess- Einrichtung vorgesehen ist und die Strom leiter durch eine Öffnung im Gehäuse zu
der Stromschliess,-Einrichtung geführt sind.
Das sähalenartige Gehäuse kann in be quemer Nähe des Fusses auf den Boden ge legt werden, so dass der Arbeiter den Schal ter betätigen kann ohne den Standort ändern zu müssen.
In der beiliegenden Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegen- standes schematisch dargestellt.
Es zeigt Fig.1 einen- Teil des Schalters im Quer- schnitt, Fig. 2 und 3 sind Schnitte nach den Linien II-11 und III III der Fig.1;
Fig.4 zeigt die Anordnung des Schal ters bei Verwendung desselben mit einer Nähmaschine. Der gezeichnete Schalter weist eine Haube 1 von schalenartiger Form aus Stahl blech, Alum;
niumguss, usw. auf. In.- einer Bohrung 2 der Haube 1 sitzt eine Muffe 3, die mittels einer Mutter 4 an der Haube be festigt ist. In der Büchse 3 sitzt ein unter der Wirkung einer Feder 5 stehender Drücker 6 aus elektrisch isolierendem Mate rial.
Am untern Ende des Drückers 6, sitzt ein Metallstück 7, das die metallischen La mellen 8, 9 leitend miteinander verbinden kann. Die Lamellen 8, 9 sitzen mittels Me tallbüchsen 10 m einem aus elektrisch isolie rendem Material 'bestehenden Halter 11, der mittels Gewindebüchse 12 mit der Muffe 3 lösbar verbunden ist. Die Büchsen 10 sind mit den Leitern 14, 15 leitend verbunden.
Diese Drähte 14, 15 sind in einem Schutz schlauch 16 angeordnet, der durch eine in der Haube 1 befestigte Büchse 17 zur Steck dose 18 und zum Motor 19 führt. -Durch Druck auf ,den Drücker 6 wird der Strom kreis über die Lamellen 8, 9 geschlossen, der Motor 19 wird eingeschaltet. Sobald der Drücker 6 freigegeben. wird, stellt der No- tor ab. Die Abmessungen sind so gewählt, dass der Kontakt 6 mit dem Fuss leicht und dauernd gedrückt werden kann, ohne dass der Fuss ermüdet.
Foot switch for small motors. The subject matter of the present invention is a foot switch for small motors, in which a spring-loaded and foot-operated current closing device is provided in a shell-like housing and the current leads through an opening in the housing
the power supply facility are performed.
The sähalen-like housing can be placed on the ground in comfort near the foot, so that the worker can operate the switch without having to change the location.
An exemplary embodiment of the subject matter of the invention is shown schematically in the accompanying drawing.
FIG. 1 shows part of the switch in cross section, FIGS. 2 and 3 are sections along the lines II-11 and III-III in FIG. 1;
Fig.4 shows the arrangement of the scarf age when using the same with a sewing machine. The switch shown has a hood 1 of shell-like shape made of sheet steel, aluminum;
nium casting, etc. on. In.- a bore 2 of the hood 1 sits a sleeve 3 which is fastened by means of a nut 4 on the hood be. In the sleeve 3 sits under the action of a spring 5 standing pusher 6 made of electrically insulating mate rial.
At the lower end of the pusher 6, there is a piece of metal 7 which can conductively connect the metallic lamellae 8, 9 to one another. The lamellae 8, 9 sit by means of Me tallbüchsen 10 m a holder 11 made of electrically insulating material 'which is detachably connected to the sleeve 3 by means of threaded bushing 12. The sockets 10 are conductively connected to the conductors 14, 15.
These wires 14, 15 are arranged in a protective hose 16 which leads through a bushing 17 fixed in the hood 1 to the socket 18 and to the motor 19. -By pressing the pusher 6, the circuit is closed over the slats 8, 9, the motor 19 is switched on. As soon as the trigger 6 is released. the notor turns off. The dimensions are chosen so that the contact 6 can be pressed easily and continuously with the foot without the foot becoming tired.
