This invention relates to a quickly releasable
hinge mechanism which may be, used for quick
release of emergency doors, life rafts, or ofan
emergency ?oatation gear.
It is an object of this invention to provide a
quickly releasable securing means between two
members. In the conventional hinge connection

be shifted to. the rightto movethe hinge pins .to
the position illustrated in Fig. 1 whereby the
plates l0 and 16 are securely hinged together.
Plates [0 and I6 may be quickly detached mere

may be separated. It isan object of this in
vention to provide a hinge connection in which
a relatively short movement of the hinge pin
means is su?icient to effect‘release of the hinge
parts. It is a further object of this invention to

the hinge may be of any desired length but‘ the
