Personal flotation equipment

Personal flotation equipment comprising:

• a circular housing securable on a wearer, said housing having a gas chamber containing gas under pressure and a flotation bag chamber containing a flexible inflatable bag having an inlet, the housing having a transverse wall separating the gas chamber from the bag chamber,
• said transverse wall having a passage extending from the gas chamber to the flotation bag chamber, said inflatable bag inlet being connected to said passage,
• a normally closed valve in said passage preventing flow of said gas under pressure from the gas chamber through the passage into the inflatable bag, and
• a circular cover releasably secured to the housing and retaining the inflatable bag in the bag chamber, said cover being manually twistable relative to the housing about an axis passing through the centres of the circular cover and circular housing to cause the cover to become detached therefrom and cease retaining the inflatable bag in the bag chamber,
• said cover carrying a valve actuator which opens said valve when the cover is moved angularly to cease retaining the inflatable bag in the bag chamber, said valve and said valve actuator lying on said axis passing through the centres of the circular cover and circular housing,
• whereby when the cover is so operated gas under pressure passes from the gas chamber through the passage into the bag to inflate the bag and thereby cause the bag to extend from the bag chamber in an inflated condition to provide buoyancy for the wearer.
