The invention relates to a door for an electric switch cabinet comprising a door leaf made of a material isolating from fire and arcs, a hinge construction at a vertical edge of said door leaf and connectable to the cabinet frame, and a locking device cooperating with the door frame at the other vertical edge of said door leaf. In order to obtain an improved hinge construction regarding tightness and strength and to make the door lockable from all sides of the frame, the invention provides a hinge construction comprising a hinge composed of slidably and pivotably interengaging profile elements, latch means provided at the upper and lower edges of the door and being adapted to engage complementary latch means provided at the frame, and a jacking or lifting mechanism for vertically displacing the door via the hinge to bring the latch means and the complementary latch means into and out of engagement relative each other.
A door for an electric switch cabinet (100) having a frame (102), comprising a door leaf (10) having a pair of spaced apart vertical edges, said door leaf (10) being made of a material isolating from fire and arcs, a hinge construction (30) at one of said pair of vertical edges of said door leaf (10) and connectable to the cabinet frame 9102), and a locking device (70) cooperating with the cabinet frame (102) at the other of said pair of vertical edges of said door leaf (10), said hinge construction (30) comprising a hinge composed of slidably and pivotally interengaging profile elements (32, 60) extending over the full length of said one of said pair of vertical edges, latch means (162, 170) provided at the upper and lower edges of the door and adapted for engagement with complementary latch means (182, 192) provided at the door frame, a jacking mechanism (120) for vertical displacing the door via said profile elements (32, 60) between a locked, lowered closed position and a raised closed position to bring said latch means (162, 170) and said complementary latch means (182, 192) into and out of engagement, respectively, relative to each other, and said jacking mechanism (120) comprising a jacking leg (150) slidably guided along said hinge construction (30) and operable for engagement with a cabinet understructure for the vertical displacement of said door.
