A swinging door and a latching mechanism for the swinging door which is pivotally mounted for movement about a first axis between fully open and closed positions the latching mechanism comprising:

• a support column pivotally mounted at one end for rotation about a second axis parallel to said first axis, said one end of the support column provided with a support block for supporting the door in the open position, an opposite end of the support column provided with a latching bar for securing the support column in a first position where said support block underlies an edge of the door in the open position;
• and
• a cam surface non-rotatably fixed to said support column and engagable by said door as said door moves in one direction from the closed to the open position to rotate said support column and said support block in said one direction to a position which permits said door to move to a fully open position without interference from the support column or the support block.
