Concise Bible Dictionary:

The only hinges handed down from antiquity are pivots projecting above and below the door, on which the door turned. In the temple the hinges were of gold, and may have been of this description (1 Kings 7:50; Prov. 26:14). In ancient existing houses with stone doors the hinges are stone projections at the top and bottom of the doors.
