Definitions

  • the present invention relates to trigger devices of the type according to the preamble of the main claim. Illustrated on the example of the triggering of a cellar pump, it nevertheless applies to any machine or installation requiring a trigger.
  • the invention solves at the same time the problems of sealing, timing and adjustment by the provisions of the characteristic part of the main claim.
  • the device shown comprises a first permanent magnet 1, housed in a housing 2 made of non-magnetic plastic.
  • This magnet 1 is carried by one end of a lever 3 held in the position of FIGS. 1 and 4 by a spring 4. In this position, the other end of the lever 3 does not close an electrical circuit 5 with a microswitch .
  • a plastic housing 6 is attached to the housing 2 and does not communicate with the latter.
  • the housing 2 and the housing 6 have a common wall 7 substantially perpendicular to the path followed by the magnet 1, when it is attracted against the force of the spring 4, with tilting of the lever 3.
  • a second permanent magnet 9 In the housing 6 is mounted for rotation about an axis 8 a second permanent magnet 9.
  • the axis 8 crosses without sealing the wall 10 of the housing opposite the wall 7.
  • the axis 8 is bent and carries at the end a float 11.
  • the magnet 9 can thus describe, according to a back-and-forth movement comes, a semicircle, whose plane is substantially perpendicular to the trajectory of attraction of the magnet 1.
  • the magnet 9 is oriented so that its polarity, when it comes in front of the place 12 (figure 2) where it is opposite the magnet 1, is opposite to that of the latter.
  • a plate 13 made of magnetic stainless steel is fixed in rotation with the magnet 9. Thinner than the latter, it applies, when it is in front of the place 12, to the magnet 1 a much less magnetic force than that that the magnet 9 applies to the magnet 1 when it is in front of the location 12. This force applied by the plate 13 is insufficient to attract the magnet 1 but is sufficient to hold it in said location 12 if there is been attracted beforehand.
  • the assembly is such that, when the second magnet 9 and the plate 13 return from place 12, the plate 13 remains in front of place 12 after the magnet 9 has already left it.
  • the device operates as follows.
  • the float 11 is at the lowest level ( Figure 1).
  • the magnet 1 and the magnet 9 are offset by a large angle.
  • the magnet 9 does not attract the magnet 1. It is the force of the spring 4 which determines the position of the magnet 1 and of the lever 3.
  • the electric circuit 5 for triggering a pump P is open.
  • the water level rises.
  • the float 11 rises and rotates the axis 8.
  • the plate 13 passes in front of the location 12.
  • the magnet 1 is not attracted.
  • the magnet 9 turns until it comes to the place 12 (figure 2). It attracts the magnet 1.
  • the electric circuit 5 closes and controls the starting of the pump P by means of an electric conductor C.
  • the crossing of the housing 2 does not raise any sealing difficulty.
  • the pump always works thanks to this maintenance.
  • the plate 13 continues to move until the magnetic holding attraction becomes less than the force of the spring 4. There is then a sudden cut.
  • This very simple device also has the advantage of allowing rudimentary positioning of the microswitch relative to the position of the control pin 8.
  • a relatively large variation in the microswitch position results in a very small deviation of the high and low levels.
  • the invention can also be applied to a switch with two fixed positions.
  • the retaining plate is replaced by a third magnet, offset from the second by an angle which will depend on the desired gap between trigger and stop level.
  • the holding plate 13 may also not be in contact with the magnet 9 or even be located inside the housing 2.
  • the microswitch can be single or double or multi-pole.
  • the magnets can be controlled by something other than a float.

Claims (7)

1. Auslösevorrichtung, gebildet durch einen ersten Magneten (1), der so gelagert ist, daß er bis an eine Stelle (12) angezogen und von dort wieder zurückbewegt werden kann, einem zweiten Magneten (9), der eine magnetische Kraft ausübt, die, wenn er vor die Stelle (12) gelangt, wo er durch eine nichtmagnetische Wand von dem ersten Magneten (1) getrennt ist, ausreicht, um den letzteren (1) an diese Stelle (12) zu ziehen und durch einen dritten Magneten (13), dadurch gekennzeichnet, daß der dritte Magnet (13) mit dem zweiten (9) verbunden und so angeordnet ist, daß er (13) sich noch nach dem zweiten Magneten (9) vor der Stelle (12) befindet, wenn die Magneten die Stelle (12) gerade passiert haben und eine derartige Anziehungskraft aufweist, daß er (13) den ersten Magneten (1) dort festhält, aber ihn nicht nach dorthin anzieht.
2. Vorrichtung nach Anspruch 1, dadurch gekennzeichnet, daß der zweite Magnet (9) durch eine hin- und hergehende Bewegung angetrieben ist.
3. Vorrichtung nach Anspruch 1 oder 2, dadurch gekennzeichnet, daß die Bewegungsbahnen, die von dem ersten Magneten (1) und von dem zweiten Magneten (9) durchlaufen werden, genau zueinander senkrecht sind.
4. Vorrichtung nach Anspruch 3, dadurch gekennzeichnet, daß der zweite Magnet (9) einen Kreisbogen beschreibt, dessen Ebene genau senkrecht zu der Bewegungsbahn ist, die von dem ersten Magneten (1) durchlaufen wird.
5. Vorrichtung nach einem der Ansprüche 1 bis 4, dadurch gekennzeichnet, daß der erste und der zweite Magnet (1, 9) in zwei Räumen gelagert sind, die nicht miteinander verbunden sind.
6. Vorrichtung nach einem der vorhergehenden Ansprüche, dadurch gekennzeichnet, daß der erste Magnet auf einem Hebel (3) gelagert ist.
7. Vorrichtung nach einem der Ansprüche 1 bis 6, bei welcher der erste Magnet (1) und der Hebel (3) in einem Gehäuse (2) eingeschlossen sind, dadurch gekennzeichnet, daß ein elektrischer Leiter (C), der Teil eines elektrischen Kreises (5) bildet, durch das Gehäuse (2) hindurchverläuft.
