  • the safety lock is of the key type encoded by means of a magnet.
  • the bolt 13 is automatically activated as a further safety measure for the user. Should the lid be closed again after opening, such movement occurs without modifying the condition of the bolt 13, which remains in its locked condition.
  • the rod 20 may recede to its initial position due to the sliding of the slot 22 leftwards, with respect to the pin 23, starting from the condition illustrated in figure 11.
  • the deactivation of the bolt 13 may be obtained only intentionally at that point by the user operating from inside through the knob 8 or from outside the door after access to the end bit 30 through the lock 9.
  • the actuation pin 26 shall first be moved axially by the user (by applying pressure on the end bit 30, or by pulling the knob 29) in such a manner to axially move the square-shaped portion 25 (figure 11) with respect to the lever 24, in such a manner to move a circular section of the pin 26 into the hole obtained in such lever.
  • the pin may be rotated, so as to actuate the bolt 13, without influencing the position of the rod 20 in any manner whatsoever, given that the pin is decoupled with respect to the lever 24.
  • the axial pressure action on the pin 26 is obtained by overcoming the elastic force of a return spring 32, which is associated to the end bit 30 (figure 13) .
  • the safety device according to the invention represents a considerable improvement with respect to the devices of the prior art in terms of safety, operating reliability, construction simplicity, efficiency and comfort of use for the user.
