Definitions

  • the invention relates to a device for transmitting a linear movement from a pushbutton element to a plunger, which is provided for actuating an in particular electrical contact and is guided relative to a base element.
  • Such a device is known for example from DE-OS 33 46 296.
  • Such an input keyboard which is used, for example, for machine tool controls, is designed in such a way that a sensing element with an associated plunger is guided in a basic element, the key restoring force being determined in each case by an elastic, bell-shaped sleeve.
  • Such a configuration of the actuating element requires a relatively high mechanical outlay.
  • the object of the invention is to design a device of the type mentioned at the outset in such a way that the production outlay, in particular with regard to the guide elements, is minimized.
  • this object is achieved in that the guiding takes place by means of two leaf spring elements which connect the plungers to the base element and are approximately parallel to one another. Because there are no sliding surfaces, the key movement is also insensitive to contamination.
  • a production-technically very favorable embodiment of the invention is characterized in that the feeler element, plunger, leaf springs and base element are designed as a one-piece molded part.
  • FIG. 1 shows a pushbutton element T which can carry out a linear movement in the direction indicated by a double arrow within a base body GK, in that two leaf spring-like, parallel webs S1 and S2 guide the pushbutton element T relative to the base body GK
  • a stop A located on it abuts a spring element F, as a result of which a push rod ST connected to the spring element F moves in the direction of the button actuation after overcoming a pressure point, not shown for the sake of clarity made electrical contact, be it a membrane keyboard or a microswitch.
  • the button T When the button T is released, it returns to its starting position at least due to the spring action of the webs S1 and S2 and allows the plunger ST to snap back, with a driver M taking the plunger ST and the spring F back into the original position.
  • the base body GK can have bores, including the bore B1, so that a defined mounting of the base body GK with respect to the switching element is possible. It is also conceivable that several key elements T are structurally combined to form a keyboard.
  • the design of the spring element F and the plunger ST is illustrated by a section I, this section I being shown in the illustration according to FIG.
  • the spring element F of the plunger ST is designed like a leaf spring, which results in two stable positions for the plunger ST.
  • the stable position when the pushbutton element T is not actuated is shown in the illustration according to FIG.
  • FIG. 3 shows section II in accordance with the illustration in FIG. It can be seen that not only the bore B1, but also an additional bore B2 can be provided for holding the base body GK.
  • FIG. 4 shows a view of the key element T corresponding to the illustration according to FIG. 2.

Abstract

Afin de mettre en ÷uvre un guidage facile à réaliser d'un élément à touche (T) par rapport à un élément de base (GK), l'élément à touche (T) et l'élément de base (GK) sont retenus au moyen de deux éléments à ressorts à lames (S1, S2) approximativement parallèles. Ce guidage est insensible aux salissures. Les éléments fonctionnels peuvent être constitués d'une seule pièce moulée.
