Security box

摘要

A security box inter alia for tools has a metal box and a lid of the swing and slide type utilizing a pair of box hinges fixed to the box and a pair of lid hinges fixed to the lid, and a pair of intermediate hinges connected to both sets of hinges by links which make all the hinges parallel and enabling the door hinge to lie outside the plane of the door opening. In a variant, there is no intermediate hinge and the lid opening angle is less. The lid and box have interengaging profiled edges which in the closed position mutually obstruct but, when the lid slides to the open position, the profiles separate and the lid is free to swing open.
