A BLAST-RESISTANT STRUCTURE

摘要

A blast-resistant structure comprising a body (1) in which is defined an aperture is disclosed. The aperture is bounded by two edge parts of the body (1). The blast-resistant structure further comprises a door (2) configured selectively to close-off the aperture; and first and second securing mechanisms (50) configured selectively to secure the door (2) to respective ones of the body edge parts. Each securing mechanism (50) comprises a locking channel (51, 52) that extends generally parallel to the body edge part and a corresponding locking pin (28) having a generally straight part that extends generally parallel to the body edge part and is moveable between an open position in which the locking pin (28) is external to the locking channel (51, 52) and a secured position in which the locking pin (28) is engaged in the locking channel (51, 52).
