Definitions

  • the invention relates to a device for extending plunger drives for electrical switching devices by means of extension elements which can be switched on between the drive and the button of the switching device.
  • cap-like extension elements which can be attached to the tappet and are positively connected in any number are provided for bridging the mounting distance.
  • This arrangement requires on the one hand a special design of the plunger drive in order to be able to put the caps on, and on the other hand loads the return springs for the plunger drive, so that these have to be designed relatively strong from the outset.
  • the extension element is connected directly to the drive of the switching device by latching or positive locking, so that the extension element drives the drive additionally burdened.
  • the invention is intended to provide a device of the type mentioned above, which makes it possible to create a simple and inexpensive device for extending buttons without loading the drive and button.
  • This is achieved in a simple manner in that the extension element ends in elastically flexible arms forming a C, the open side of the C engaging over the button of the switching device and the arms being attachable to the switching device.
  • the attachment of the extension element is advantageously achieved in a simple manner in that the arms end in elastically flexible latching projections which can be snapped into openings in the switching device.
  • the openings can advantageously be the screwdriver guides of connection screws.
  • a pressure piece that continues the extension element is formed in the inner region of the C.
  • extension element is designed as a plastic part with a cross-shaped cross section.
  • the extension element is provided with division notches transversely to the longitudinal direction. This makes it possible to adapt the extension element, for example with the aid of a knife, to the distance between the cabinet door of the control cabinet and the button of the device fastened in the control cabinet.
  • the device according to the invention can be used not only to actuate command switches, but also advantageously for reset buttons for overcurrent relays and the like. An exemplary embodiment of the device according to the invention is described with reference to the drawing and the mode of operation is explained in more detail.
  • the device 2 fastened to the wall 1 of the control cabinet in FIG. 1 is an overcurrent relay with a reset button 3 for resetting the triggered relay.
  • the device 2 is fastened to the wall 1 of the control cabinet in a manner not shown, for example by screwing.
  • a rosette 5 is attached in the usual way as a tappet drive, which acts on the extension element 6 when the push button of the tappet drive is actuated.
  • the extension element 6 is rod-shaped and ends at the end facing away from the rosette 5 in elastically flexible arms 7, 8 forming a C.
  • the arms 8, which are designed to be elastic, form an open leaf spring which on the one hand holds the extension element 6 and on the other hand pushes back into the starting position.
  • the arms 7, 8 are held on the device 2 by means of locking projections 9 which snap into openings 10 in the device 2.
  • the design of the locking projections 9 with respect to the openings can be seen particularly clearly in FIGS. 4 and 5.
  • the extension element 6 has a cross-shaped cross section.
  • the extension element ends in a pressure piece 11, which is located in the inner region of the C and is particularly advantageous when there are reset buttons that are aligned with the end face of the device 2.
  • there are dividing notches 12 on the extension element 6, which enable the length of the extension element 6 to be adjusted in relation to the distance between the rosette 5 and the reset button 3.
  • the actuating force is transmitted to the reset button 3 via the extension element 6 and the pressure piece 11.
  • the resilient arms 7 and 8 deform, which are supported on the attachment points on the device 2. After releasing the tappet drive, it goes through your own, for example Restoring force in the starting position and the extension element is also pushed back into the starting position by springing back the arms 7, 8. It is therefore an extension that does not additionally stress the return spring of the rosette 5 or that of the button 3. Due to the cruciform cross-sectional shape of the extension element 6, it is inherently torsion-resistant, so that larger forces can also be transmitted.
  • the extension element can be attached to the device without tools and difficulties and can be adapted to the various uses without difficulty due to the division notches. Any desired spring stiffness can be achieved through the choice of material and dimensions of the arms 7, 8.
