  • Patent number: 4754715
    Abstract: An improved safe is provided which offers the security of currently known more complex safes at substantially less cost. The safe preferably includes a cabinet having apertured door frame structure, with a door having inner, outer and sidewalls. Locking apparatus located within the door includes a series of selectively operable toggle mechanisms, each having a pair of pivotal links coupled to a locking bolt. The locking bolts are designed to extend through the aligned frame and door apertures to lock the door. The frame structure is formed of interconnected, seamless webs integral with the cabinet walls and presenting a recess to receive the door lip. Additional security is achieved by reinforcing the door lip with flange structure forming a part of the marginal door frame and by attaching the handle to the actuator for the toggle mechanisms so that excess force renders the handle inoperative.
