Definitions

  • The. invention relates to an emergency shutdown device according to the preamble of Claim 1 and an emergency shutdown device according to the preamble of the claim Second
  • the invention is therefore based on the object, the reproducibility of the Increase trigger behavior of emergency shutdown devices.
  • the actuation button is by the tension spring or the return spring and the blocking body prevented from being in its unactuated state from its rest position to get.
  • the control button When you press the control button, the backdrop against the tensioning force of the tension spring until it moves in the guide part stored locking body from the engagement of the locking bevels the locking surfaces on the backdrop are released, causing the actuating plunger due to the energy released by the tension spring is moved against the contact element.
  • the Actuation button and the driver of the actuating plunger When resetting, the Actuation button and the driver of the actuating plunger withdrawn as far as until the locking body over the engagement of the bevels on the backdrop again get into the engagement of the bevels on the actuating plunger.
  • the the actuating plunger interlocking backdrop is in one case by the Tension spring and the other case by the return spring in their starting position brought back. In this case, the tension spring is activated and in the other case cocked when resetting the operating button.
  • the graded areas are graded with a slope, the runs in such a way that the locking body in the course of the operation or Resetting the control button a movement component vertically to the actuation direction of the actuation button.
  • the blocking areas can be concentric or even parallel, circumferentially perpendicular or arranged obliquely or radially to the central axis of the emergency shutdown device his.
  • the direction of the gradation of the blocking surfaces can be radial, vertical tangential, oblique tangential or parallel to the central axis. From this it can be seen that by appropriate arrangement of the blocking areas and their bevels the displacement of the locking body in the recesses of the guide part for triggering or locking the actuating plunger radial, tangential or parallel to the central axis of the emergency shutdown device takes place or from a composition of the aforementioned Relocation movements exist.
  • the invention can be transferred advantageously to emergency shutdown devices, on the one hand are operated in a translatory, rotary or translatory-rotary manner and on the other hand, the actuating plunger inside or outside the Backdrop is arranged.
  • a blocking body can advantageously be spherical or cylindrical rigid body, which in the latter case is rectilinear in one direction interacting blocking areas, use.
  • the Locking body can be connected integrally with the guide part.
  • the emergency shutdown device 1 has a tubular stationary one Guide part 4 and an actuating button 6 provided.
  • On the guide part 4 is the actuating button 6 by means of a backdrop attached to it 8 slidably mounted.
  • a backdrop 8 In the backdrop 8 is an actuating plunger 10 for shown contact elements arranged.
  • the actuating plunger 10 is over a driver 12 connected to the actuating button 6 in or against the actuation direction D slidably coupled to the backdrop 8.
  • a pressurized tension spring 14 is supported on corresponding surface elements between actuating button 6 and actuating plunger 10.
  • the Setting 8 and the actuating plunger 10 are opposite with locking surfaces 16 or 18 equipped.
  • the blocking surfaces facing the central axis 20 16 of the backdrop 8 are each made of first partial areas 22, opposite these outwardly recessed second partial surfaces 26 and the partial surfaces 22 and 26 connecting bevels 30 composed. That of the central axis 20 facing locking surfaces 18 of the actuating plunger 10 are each made first sub-areas 24, in relation to this second set back Sub-areas 28 and the two sub-areas 24 and 28 connecting bevels 32 composed.
  • the blocking surfaces 16 and 18 are therefore vertical to the actuation direction D and offset from the central axis 20 to the outside.
  • In recesses 34 of the guide part 4 are spherical rigid locking bodies 36 mounted, which rest on both locking surfaces 16 and 18.
  • the emergency shutdown device 2 differs from that above described in that appropriate surface elements the prestressed tension spring 14 between the guide member 4 and the actuating plunger 10 and a pressurized return spring 38 between Actuating button 6 and guide part 4 supports.
  • the invention can also be used with cylindrical locking bodies 36 perform, in which case the blocking surfaces 16 and 18 each flat first partial surfaces 22 and 24, second partial surfaces 26 and 28 and assemble slopes 30 and 32 respectively.
