    摘要: A mechanism for securing a door to a door frame includes a plurality of generally C-shaped clamps rotatably secured about the door's periphery, each of the clamps including a rear radial clamp leg engageable with the rear of the door frame, a forward radial clamp leg overlying the front surface of the door, and a connecting base extending between the radial legs, with inner cam surfaces on each radial leg and an outer cam surface on the forward radial leg. A plurality of wedges are slidably secured to the door front surface for radial movement between extended and retracted positions wherein the wedge respectively engages or does not engage the inner cam surface on an associated forward clamp leg to effect latching or unlatching of each clamp about the door and frame. Each wedge includes a cam block carried by an arm overlying an associated clamp and spaced radially outwardly of the wedge cam surface to engage said outer cam surface of the associated forward clamp leg to move the rear clamp leg from the door frame as the wedge is moved to its retracted position.
