Definitions

  • This invention relates to a safety lock which is particularly suitable for being miniaturized and adapted, for example, to payphones accepting and collecting coins in a box.
  • This invention relates to a lock, which is operated by an electronic device controlling a mechanical part, whereby the lock operates according to the principle that the striker on the door of the box engages the rocking lever integral with the body of the box; between the hook on the striker and the dog iron on the rocking lever there is a negative angle, preferably between approx. 1° and 10°, while between the door and the body of the box there is a certain clearance, closing which, for example by applying a slight pressure on the door and contemporaneously activating the electronic opening device, it is possible to disengage the striker and the rocking lever and, therefore, to open the door.
  • the lock has been designed to be opened by means of an electronic device, which controls the mechanical part, only after the recognition of a user code entered on the lock itself, by means of an electromagnet or the like, which attracts the rocking lever, making it rotate around a pivot and thus disengaging it, said electronic device being one of the subjects of the patent application RM 96 A/000829 filed by the same applicant.
  • the electronic safety lock contemplated and described hereunder is essentially composed of the following:
  • a characteristic of the mechanical part of the lock is that, when it is closed, the angle formed by the rocking lever hook and the striker hook is negative by about 1° to about 10°, thus engaging the two hooks in a virtually inviolable position.
  • the lock may be opened only after the electromagnet has received the necessary energy to attract the rocking lever and only if the user, by pressing the door, closes the minimum clearance of several millimetres (between approx. 0.2 and 0.8) between the body and the door, thus allowing the rocking lever hook to disengage itself from the striker hook and to rotate, until stopped in the open-lock position by the specific elastic means.
  • Fig. 1 shows a view from above of the plan of the lock.
  • Fig. 2 shows a view from above of the lock featured in fig. 1, in the open position.
  • Figs. 3 to 7 show a plan of the engagement details and of the resetting tooth in the various positions, from closed to open.
  • the electronic safety lock is shown mounted on a box, or the like, but it may also be installed on any kind of door.
  • the striker 11 fastened by means of screws or the like, on the door 3 hinged to the body 1, by means of the hinge 2, consists of an elongated element, substantially shaped like a parallelpiped, on whose internal face, for about 3/4 of its length, there is a hook 11a, after which the striker continues with a reduced width to the end, where there is a resetting tooth 12, which may clearly be seen in the detail shown in Fig. 3, hinged in 13 and provided with a spring 14, which always positions it at 45° to the horizontal axis of the striker.
  • the body 1 is fastened, by means of a base 4, with screws or the like, the set comprising the rocking lever 8, an electromagnet 10, and electronic opening components.
  • the rocking lever 8 rotates around a pivot 5 and presents a spike 8a, which departs from a substantially rectangular body pivoted in 5 and provided with a spring coaxial with the pivot 5, kept in a loaded position by the reaction pin 7.
  • An electromagnet 10 attracts the rocking lever, which features a metal plate 8b on the face toward the electromagnet, thus making it rotate.
  • This movement occurs when the user, by means of an electronic device which is the subject of a previous patent by the same inventor, by means of an infrared transmitter sends energy and certain predetermined codes to an infrared receiver, which checks the correspondence between the received code and the set code and powers the electromagnet 10, which thus attracts the rocking lever 8.
  • the negative angle between the spike 8a of the rocking lever 8 and the hook 11a of the striker allows the opening of the lock, after the activation of the electromagnet, only if the clearance of a few millimetres between the door and the body has been suitably closed, so that the hook 11a of the striker 11 moves inward, thus disengaging the spike 8a of the rocking lever 8.
  • This negative angle absolutely prevents the lock from being forced or picked since, when the electromagnet is not activated, the more the door is pulled outward, by means of a crowbar or other such instrument, the stronger becomes the engagement between the spike 8a of the rocking lever 8 and the hook 11a of the striker.
  • the resetting tooth 12, located at the end of the resetting device 13 engages the tooth 8c, located on the end of the face parallel to the striker 11 of the rocking lever 8, determining the rotation of the rocking lever 8, which moves from the angled open-lock position, toward the opposite side of the striker 11, to the closed-lock position, parallel to the longitudinal axis of the striker 11, while at the same time engaging the spike 8a of the rocking lever with the hook 11a of the striker and locking the door with absolute safety.
