ABSTRACT:
A personal flotation assistance device includes a housing having an open end, a cover pivotally movable from a first position closing the open end and a second position opening that end, a container of pressurized fluid having a frangible membrane, a pin for puncturing the membrane, an expandable envelope disposed in an initially collapsed condition, and a gear assembly connecting the cover and pin. User manipulation of the cover to move the same from its first to its second position causes pin movement both rotationally about its axis and translationally along that axis into membrane puncturing abutment, thereby releasing the pressurized fluid for inflating the envelope to provide the user with flotation assistance. Cover movement to its second from its first position additionally serves to clear the housing open end thus enabling expansion of the inflating envelope outwardly from the housing interior.
