A box comprising a box bottom part and a lid part which is pivotably supported relative thereto by means of a hinge device between an open and a closed position is particularly suited for use in the Ex area. The hinge device comprises a lower hinge part assigned to the box bottom part and an upper hinge part assigned to the lid part, which are pivotably connected to each other. To provide a permanent connection between lid part and box bottom part in a simple way and at low costs, while simultaneously said parts are pivotable relative to each other in a safe way, one hinge part is slidably supported and the other hinge part is arranged to be at least partly screw-mountable in the respectively assigned box bottom part and lid part, respectively.

A safety gate for use in household openings, such as doorways, hallways, and stair landings. The gate includes a color-coded closed/opened status indicator. In some embodiments, the barrier may be unlocked and locked with one-handed operation. The gate may include an automatic closure mechanism for moving the door from the open position to the closed position.

Gate hinges include an anchor shaft defining a shaft axis that extends between a first end and a second end. A first support arm is arranged at a position closer to the first end than the second end and extends in a direction normal to the shaft axis from the anchor shaft and a second support arm is arranged at the same axial position as the first support arm along the anchor shaft and extends in a direction opposite the first support arm. The anchor shaft includes a first thread and a second, self-tapping thread. The first thread is arranged along the anchor shaft for an axial length between the first and second support arms and the second thread and the second thread extends axially from the first thread to a tip of the anchor shaft at the second end.
