Definitions

  • the invention relates to a disengageable stator safety lock of the type which includes a body in which is housed a stator associated with disengageable means intended to block its rotation relative to said body, said stator being able to rotate in said body when it is subjected to a torque exceeding a predetermined value, said stator being opposite a thresher which can pivot relative to the body, said stator being, in addition, associated with a driving element movable relative to the stator between a position in which said element is engaged in the thresher and a position where said element is released from said thresher, said stator being provided with a rotor which can pivot inside and which is associated with means for blocking its rotation relative to the stator, a key being intended to be introduced into the rotor to cooperate with said locking means and to erase them in order to release the rotation d u rotor relative to the stator, said driving element being able to move in translation relative to this rotor, complementary guide means being provided between the driving element and the stator
  • Such devices have been designed to overcome the drawbacks of conventional type locks simply comprising a rotor movable in axial rotation in a stator, said rotor being locked relative to said stator, when the key of the lock is not inserted in its housing, using retractable means.
  • Such conventional locks are, in fact, insufficiently resistant and can be easily forced, in particular by exerting a large torque on the rotor by means, for example, of a dummy key, in order to damage and render ineffective said retractable locking means. .
  • EP-A-0 341 132 belongs to the state of the art according to article 54 (3) and (4) EPC for the states jointly designated DE, ES, GB, IT and SE.
  • This document shows a lock of the kind defined above, in which the driving element is linked in rotation to the rotor while being able to move in translation relative to this rotor, while the key is suitable for driving the rotor in rotation; these characteristics are common to this document and to claim 1 of the set of claims for the common states DE, ES, GB, IT and SE.
  • the driving element is located partly outside the stator and cooperates by a transverse bearing surface with a front end wall of the stator. Such an arrangement leads to a certain longitudinal bulk and does not allow a positive control of the movement of the driving element in both directions.
  • the invention defined by claim 1 for the states designated in common, is distinguished in that the driving element is arranged inside the stator and that the facing walls of the driving element and the stator are provided, one of at least one element protruding in the radial direction, the other of at least one element forming a groove which extends continuously over a portion of a tower and comprises at least a part of helical shape and a part in an arc.
  • EPC corresponds to GB -A- 2 005 335.
  • This document concerns a disengageable stator lock which is rotated with the rotor if a non-conforming key has been inserted into the rotor.
  • a conforming key has been inserted into the rotor, a 180 ° rotation of the key and of the rotor allows a driving element, linked in rotation to the stator, to move in translation relative to the rotor and to engage in a threshing piece.
  • the rotation of the thresher can then be controlled by acting on the stator. It is therefore not the key which directly controls the rotation of the thresher and it is necessary, in a way, to proceed in two stages to control the opening of the lock.
  • the object of the invention is, above all, to provide a safety lock with a disengageable stator, in which all the movements of the various members for opening or closing are controlled solely from the rotation of the key. It is also desired that the driving element at rest is in the disengaged position of the threshing machine, so that an attempt at forcing, with a non-conforming key, does not cause the translational movement of the driving element, unlike in the case of EP-A-0 212 468.
  • the lock be of a robust construction and as economical as possible, while ensuring particularly reliable operation.
  • a lock of the kind defined above is characterized in that the driving element is linked in rotation to the rotor.
  • Such safety locks are, in fact, more convenient to use, since to actuate the threshing machine, an operator need only rotate the key of said lock on itself. They are, moreover, less easily deteriorated since the flakes associated with the rotor simply have the function of locking the latter in rotation relative to the stator and do not have to be supported by their face, on the walls of the stator.
  • said driving element can pivot inside the stator, their facing walls being provided, one with at least one protruding element, the other with at least one groove element, one of these elements extending continuously over a portion of a tower and length of the wall on which it is arranged.

  • the element which extends over a portion of a tower and the length of the wall on which it is arranged comprises a plane of symmetry passing through the pivot axis of the driving element in the stator, said plane passing by at least one point of said element from which said element extends towards the threshing machine.
  • the lock comprises at least two protruding elements and two groove elements distributed symmetrically on the walls on which they are arranged with respect to a plane of symmetry passing through the pivot axis of the driving element in the stator.
  • the element which extends over a portion of the tower and the length of the wall on which it is arranged is preferably a light passing through the wall of the stator, said light cooperating with a pin of the driving element.
