Abstract

A lock comprising, within a box-like supporting body and associated with actuation elements which are available to the action of the user and/or of other devices, three locking beaks: two first lateral ones, whose free tips are shaped so as to form mutually opposite claws which lie on the plane of the closure and opening movement, and a third central beak, which is kinematically connected and coordinated with respect to the two first beaks and is provided, at its free tip, with at least one locking element. The three beaks define, in association with the actuation elements, at least two stable working positions: a first open position, in which the beaks lie substantially completely within the box-like supporting body, and a second closed position, in which the beaks protrude from the box-like supporting body with their free tips so as to lock the components with which they are associated.

Dependent claims

A lock, comprising, within a box-like supporting body and associated with actuation means which are available to the action of any of a user and of other devices, two first lateral locking beaks having free tips shaped so as to form mutually opposite claws lying on a plane of a closure and opening movement, said lock further comprising:

a third central beak, which is kinematically connected and coordinated with respect to the two first beaks;
at least one locking element, provided at a free tip of said third beak, said three beaks defining, in association with said actuation means, at least two stable working positions:
a first open position, in which said two first beaks and said third beak lie completely within said box-like supporting body, and a second closed position, in which said two first beaks and sad third beak protrude from said box-like supporting body with said free tips thereof so as to lock components with which the beaks are associated, said third beak acting as a bolt;
and
two first mutually opposite tabs formed on the contour of said third beak, said first tabs providing a corresponding number of stoke limit abutment surfaces for said two first beaks both during closure and during opening.

a third central beak, which is kinematically connected and coordinated with respect to the two first beaks;
at least one locking element, provided at a free tip of said third beak, said three beaks defining, in association with said actuation means, at least two stable working positions:
a first open position, in which said beaks lie substantially completely within said box-like supporting body, and a second closed position, in which said beaks protrude from said box-like supporting body with said free tips thereof so as to lock components with which the beaks are associated;
and said actuation means comprising two pairs of plates, each pair being constituted by a first plate, which is fixed to said supporting body and is provided with three first linear guides, said first linear guides being constituted by walls of a corresponding number of slotted holes provided at said first plate, and by a second plate, which is movable parallel to said first plate, said second plate being provided with three second guides, said second guides being constituted by walls of a corresponding number of slotted holes, provided at said second plate, which are L-shaped and correspond to said first guides, each one of said second guides being formed by a portion which is inclined with respect to the corresponding first guide, and by a portion which is perpendicular to said corresponding first guide;
and three pivots which are slidingly inserted in said first and second guides, said pivots being pivoted at through holes of said corresponding beaks, so as to determine movement of the beaks when said second plate slides.
