Lock, particularly for suitcases, trunks and the like

A lock for suitcases, trunks and carrying cases, comprising:

• a first and a second half-shells;
• at least one block which is hinged at a first end thereof to a pivoting axis, to the first half-shell;
• and
• a lever, which is hinged to said block at a first lever end portion;
• wherein
• said block is constituted by two lateral arms which by a crossmember so as to form a U-shape with a concavity comprised between said two lateral arms, said crossmember forming said pivoting axis and said concavity comprised between the two lateral arms accommodating at least one portion of said lever, said block having, extending from each one of said lateral arms, a respective tab that protrudes on an opposite side with respect to the pivoting axis,
• wherein said block is able to rotate about said pivoting axis from a configuration for closing together the first and second half-shells, in which said tabs are suitable to be engaged elastically and detachably with a perimetric ridge that protrudes from the second half-shell, to couple the first half-shell to the second half-shell, to a configuration for opening the first and second half-shells, in which said tabs are suitable to be disengaged from the ridge, and vice versa;
• and wherein
• said lever has a second end portion thereof that is suitable for gripping, and is opposite to the first end portion in order to actuate rotation of said block and disengagement of said at least one tab from said ridge, with consequent transition from the closed configuration to the open configuration, said lever having further a protrusion that is shaped so as to engage by interlocking elastically the ridge at said closed configuration, in order to strengthen coupling of the first half-shell to the second half-shell, said protrusion being disengageable from the ridge independently of said block.
