  • the support 12 is fixed to the driving protrusion by embedding or screwing or gluing.
  • the support 12 is made of a non-magnetically conductive material. In other words, the support 12 must not be affected by or affect the magnetic field of the magnetic element 8.
  • the magnetic field generated by the neodymium 8, or in general magnetic element 8, is contained in a much localized zone and this enables to obtain a greater reading precision of the position of the driving protrusion 14.
  • the support 12 can be a brass element shaped by turning or aluminium element, or nonferrous metal alloy element, or can be made of moulded plastic material or another suitable material.
  • the magnetic element 8 is fixed to a motion transmission element (T1 or T2) connected to the respective drive unit (3 or 4) and intended for being connected to a corresponding bolt (7a or 7b).

  • This reversible fitting feature confers great versatility on the lock unit 1 that thus adapts easily to specific assembly and use needs.
  • the magnetic switch unit W is connectable to the electric motor M by an extendible spiralled connection/supply cable. Owing to this connection/supply cable, the control signal generated by the magnetic switch unit W reaches the electronic control unit of the electric motor M and enables the operation thereof; the operation of the electric motor M is enabled only when the magnetic element 8 and at the reed phial sensor 9, i.e. when the motion transmission elements T1, T2 are in the most retracted position.
  • the electric motor M is activated when the aforesaid first drive unit 3 and/or the aforesaid second drive unit 4 are in the first angular position A1.

  • the electric motor M is not activatable. It is further pointed out that it is impossible to drive the electric motor M even when the bolts are partially extracted. In fact, even with the bolts in a partially extracted position, damage could occur if the electric motor M were driven.
  • the electric motor M can be driven only when the magnetic element 8 has reached completely the most internal position thereof (angular position A1). More precisely, in the angular position A1, the neodymium 8 interacts with the reed phial sensor 9; only in this condition, the magnetic switch unit W enables, or "switches on" the electric motor M.
  • the switch unit W simply does not supply the consent signal to the control unit of the electric motor M.
  • the position indicating controlling means W comprises a magnetic proximity sensor to detect the position of the first drive unit 3 and/or of the second drive unit 4, and a LED ( light emitting diode ) unit that lights up to signal a given position of the first unit 3 and/or of the second drive unit 4.
  • a visual light signal is sent that alerts the user about a closed condition of the lock: the thus alerted user, before activating the electric motor, can disengage the bolts from the respective blocking seats by rotating the cylinder C by the key K.
  • the position indicating controlling means W comprises a proximity sensor ("activatable” part 9), that can be of inductive, capacitive, ultrasonic or optical (or photoelectric) type.

  • an "activator" element which does not form part of the present invention, can be provided on a movable part that can be a drive unit 3 or 4 (cogwheel 3 or 4) or alternatively can be a motion transmission element T1 or T2, that is connectable to a corresponding bolt.
  • the proximity sensor included in the position indicating controlling means W is configured to enable the operation of the electric motor M when the first drive unit 3 and/or the second drive unit 4 is in the first angular position A1.
  • the operation is based on the principle of the reluctance variation that has an electromagnet (to be positioned on the printed circuit board 10 instead of the reed phial 9), when an element (fixed to the protrusion 14) made of ferromagnetic material is positioned in the vicinity.
  • the presence of ferromagnetic material inside the magnetic field facilitates the closure of the field with a resulting reduction of the reluctance.
  • the inner circuits of the sensor detect the reluctance variation, and, after a certain threshold has been exceeded, switch the output signal.
  • an armature is positioned on the printed circuit board 10 in a fixed position (instead of the reed phial 9), and the other armature, that is movable and is made of electric conductive material, is coupled with the protrusion 14.
  • the presence of the movable armature in a position near the fixed armature generates an electric capacity that the inner circuits detect, signalling in this manner the position of total opening of the bolts.
  • the position indicating controlling means W can comprise a microswitch, for example a lever or a button or something else suitable.
  • the microswitch will be positioned instead of the reed phial 9, and the lever thereof, or button or equivalent part, will be configured to be moved mechanically by a movable part like the protrusion 14 or element fitted on the latter, instead of the magnetic element 8.
  • the activatable part 9, placed in a stationary position is defined by the microswitch, whilst the movable “activator” element 8 is represented by the protrusion 14, or a suitable element fixed to the latter.
  • the lock unit 1 successfully performs the task of overcoming the previously mentioned drawbacks relating to a possible risk of damage to the electric motor due to the lock being forgotten in the locked position.
  • the user no longer has the task of checking the position of the lock unit; enabling the electric motor is automatic and is caused by the switch unit W on the basis of the position signal associated with the drive unit 3 or 4.
  • the object is achieved of providing a solution that, in addition to being constructionally and functionally simplified, frees the user from the annoying and not always easy task of having to ascertain the correct operating status of the lock before each activation of the electric motor.
  • the lock unit 1 according to the invention being structurally and functionally simplified, is also an advantageous solution from the financial point of view.
