Definitions

  • the invention is therefore an object of the invention to provide an overload release available, which can continue to trigger reliably when contaminated.
  • the advantage here is that pollution can be absorbed by the created next to the hump depressions in Entklinkungs Scheme. As a result, an increase in friction in the unlatching area is prevented or reduced. Debris settling on the hump can be transported away from the hump by the process of latching. Characterized in that the latch surface or Verklinkungs Structure have a hump, the contact surface between the pawl and power storage is defined in more detail.
  • the pawl and the energy accumulator each describe a circular movement about a respective fixed center.
  • the line-shaped projection is formed parallel to the direction of movement of the pawl or the energy store.
  • FIG. 1 an inventive energy storage 200 is shown.
  • the energy storage 200 has a Verklinkungs Colour 201 on.
  • a hump 210 is attached on this Verklinkungsisation 201 .
  • the hump 210 causes contaminants, which deposit thereon during a triggering process, to be transported into the depressions on the right and left of the hump 210.
  • the contact surface of the projection 210 of the energy accumulator 200 is not covered with dirt. It does not increase the friction.
  • the overload release 500 comprises a force accumulator 200, which cooperates with a pawl 100, wherein the pawl 100 is provided with a pawl surface 101 and the energy accumulator 200 with a Verklinkungs Colour 201. In the latched state, these two surfaces 101 act; 201 together mechanically. In the unlatched state in case of overload, the latch surface 101 is released from the Verklinkungs Structure 201 to release the movement of the energy storage 200th
  • the overload release 500 off FIG. 3 includes a force storage 200 and a pawl 100.
  • the pawl 100 cooperates with the energy storage 200 to release the energy stored in the energy storage 200. According to the FIG. 3 this means that the pawl 100 must be rotated counterclockwise to release its fixed center 105 and the energy storage 200 clockwise about its fixed center 205.
  • bimetals 501; 502 shown in FIG. 3 are also bimetals 501; 502 shown. These bimetals 501; 502 actuate a trigger slide 300 in case of overload, that they according to the FIG. 3 In case of overload, bend to the left and take the release slide 300 in this direction.
  • the Indian FIG. 1 Hump 210 shown on Verklinkungs Chemistry 201 of the energy accumulator 200 cooperates with the pawl surface 101 of the pawl 100. It is advantageous that the hump 210 provides a well-defined support or contact surface on which due to the interaction with the pawl 100 no dirt can be deposited. If soiling is deposited on the hump 210 in the event of triggering, then this contamination is transported away from the hump 210, for example, into the recess next to the hump 210 on the Verklinkungs Colour 201 when latching.
  • a projection 110 is arranged on the latch surface 101.
  • This projection 110 also offers the same advantages as the projection 210 of the energy accumulator 200. Although contaminants can accumulate on the projection 110 when triggered, this contamination is transported away from the projection 110, eg into the recess next to the projection 110, when latched.
  • FIG. 4 an inventive energy storage 200 is shown.
  • the energy storage 200 has a Verklinkungs Colour 201.
  • On this Verklinkungsisation 201 are a plurality of humps 210; 210a attached.
  • the humps 210; 210a cause contaminants, which are deposited thereon during a triggering process, in the recesses on the right and left of the projections 210; 210a can be transported.
  • the contact surface of the bosses 210; 210a of the energy storage 200 is not covered with dirt. It does not increase the friction.
  • the linear humps 210; 210 a are formed perpendicular to the direction of movement of the pawl 100 or the energy accumulator 200.
