Lock Device

A lock device for a door comprising:

• at least one handle suitable for being gripped and turned from a rest configuration to an actuation configuration;
• an engagement unit suitable for engaging the door shutter to a jamb thereof in a forward configuration and suitable for releasing shutter from the jamb in a retracted configuration;
• connecting means suitable for mechanically connecting handle with engagement unit, so that the rest configuration of the handle corresponds to the forward configuration of the engagement unit and the actuation configuration of the handle corresponds to the retracted configuration of the engagement unit;
• return means suitable for constantly influencing the handle from the actuation configuration to the rest configuration;
• a seating unit suitable for being mounted through the door shutter, the handle and the engagement unit being coupled to the seating unit, seating unit comprising
• a) a first seating body and a second seating body, reciprocally engaged so as to form a room wherein the engagement unit engages with the connecting means, seating bodies exhibiting each a front room wherein there are seated return means;
• wherein first seating body and second seating body are slidingly engageable to each other, for adapting the length of seating unit to the door shutter thickness, between a maximum extension configuration and a minimum extension configuration;
• and wherein first seating body comprises a first bottom, wherein there is obtained seating room, and at least a first guiding wall, axially projecting from first bottom on the side opposite seating room;
• and wherein second seating body comprises a second bottom, wherein there is obtained seating room, and at least a second guiding wall, axially projecting from second bottom on the side opposite seating room;
• and wherein the first guiding wall and the second guiding wall are slidingly engageable;
• and wherein in minimum extension configuration, wherein the distance between the first bottom and the second bottom is the minimum structurally possible, second guiding wall penetrates at least partly in first bottom.
