Patent ID: 8328252

Claim:
A grip assembly, for gripping elements constituted substantially by two mutually articulated half-shells which form an internal containment compartment, the grip assembly comprising at least one grip hand, which can be actuated on command, according to predefined paths, for the removable gripping and transport of selectively one among a plurality of containment trays for the half-shells, said gripping occurring at a perimetric portion having a predefined shape that is common to all of said trays, each of said trays comprising at least one seat having variable dimensions at its central portion for accommodating half-shells of various formats, each of said trays further comprising two recesses for fixing two respective handles, said grip hand comprising tips that can be coupled detachably to said respective handles for gripping each tray, said grip hand comprising a plate that is elongated along a main axis, said tips being arranged at end portions of said plate with respect to said main axis, said tips protruding at right angles from said plate and being movable along a direction that is parallel to said main axis and along a direction that is perpendicular to said plate for the passage of said grip hand from a free configuration to a gripping configuration of said tray, and vice versa, each of said tips comprising a strip, which can move along said direction that is perpendicular to said plate, said strip abutting elastically against a top of a respective handle of said two handles for passing from said free configuration to an intermediate configuration, in order to allow translational motion along the direction that is parallel to said main axis of a protrusion, which is functionally associated with said tip, in order to engage in a cavity that is formed in said respective handle and provide the transition from said intermediate configuration to said gripping configuration.
