Definitions

  • the present invention relates to a device for preventing the unlawful opening of an electric lock.
  • the device according to the present invention obviates this (see figures 2, 3, 4 and 5); by virtue of this device, the spring latch is blocked as soon as the reloading piston retracts into the casing when it abuts against the doorjamb.
  • the slot 52 is elongated in the direction of the stem 13, and has such a width as to allow the collar 18 to enter it with a peripheral portion.
  • the collar 18 acts like a cam which, according to its position, keeps the plate at two levels.
  • the slot 53 also has dimensions sufficient to receive a peripheral portion of the collar 38, and one edge 54 thereof is meant to abut against the collar 38, as will become apparent hereinafter.
