Definitions

  • the invention relates to a device for extension of plunger drives for electric suitsge - councils means Switchable between the actuator and button of the switching device extension members.
  • cap-like extension elements which can be attached to the tappet and are positively connected in any number are provided to bridge the installation distance.
  • This arrangement requires on the one hand a special design of the tappet drive in order to be able to put the caps on, and on the other hand loads the return springs for the tappet drive, so that these must be designed relatively strong from the outset.
  • 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 in overcurrent relays and the like.
  • 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 as a tappet drive in a conventional manner, which acts on the extension element 6 when the push button of the tappet drive is pressed.
  • 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 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 runs into a pressure piece 11, which in The inner area of the C lies and is particularly advantageous if there are reset buttons that are aligned with the end face of the device 2.
  • there are division notches 12 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 rosette 5 i.e. the plunger in the rosette 5 is actuated
  • 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 returns to the starting position, for example, through its own restoring force, 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.
