Abstract: An inflation device for an inflatable article comprises a housing for supporting a container of pressurized fluid and for supporting piercing means which is displaceable from a retracted position to penetrate the container and allow release of pressurized fluid, said container being contained within a protected casing which is secured non-releasably to the housing thereby to prevent removal of the pressurized container.

Abstract: An inflation device 10 for an inflatable article comprises a housing 11 for supporting a container 15 of pressurized fluid and for supporting piercing means which is displaceable from a retracted position to penetrate the container and allow release of pressurized fluid, said container being contained within a protected casing 20 which is secured non-releasably to the housing thereby to prevent removal of the pressurized container.

Abstract: An inflation device 10 for an inflatable article comprises a housing 11 for supporting a container 15 of pressurised fluid and for supporting piercing means which is displaceable from a retracted position to penetrate the container and allow release of pressurised fluid, said container being contained within a protected casing 20 which is secured non-releasably to the housing thereby to prevent removal of the pressurised container.

Abstract: An inflation device mechanism (10) for inflation of an inflatable article comprises a housing (11) for supporting a container (18) of pressurised fluid and a piercing device (16) displaceable from a retracted position to penetrate the container to release pressurised fluid, bias means (22) to move the piercing device to penetrate the container, and actuation means comprising co-operating latching elements (26, 30) which, in an engaged, latched configuration, retain the piercing device retracted, said actuation means being actuable by either a first (35) or a second (36) control member to allow the latching elements to disengage and permit the piercing device to penetrate the container under action of the bias means, the first control member (35) comprising a water sensitive member which surrounds the latching elements and has a strength sufficient normally to support the latching elements in the engaged configuration but to allow the elements to disengage when reduced in strength by exposure to water, and the

Abstract: An inflation device (5) for an inflatable article (such a life jacket), includes a housing (8) for holding a container of pressurised fluid (6), a displacement means (12) including a piercing means (15) displaceable so as to penetrate the container (6) and allow the release of said pressurised fluid, and actuation means (23, 27, 28, 29) having engaging co-operating elements (17, 25) which engage to retain the displacement means (12) in an unactuated configuration. The actuation means (23, 27, 28, 29) release the displacement means (12) both through the presence of water or by manual operation. The co-operating elements (17, 25) are substantially radially arranged. The line along which the displacement means (12) acts may be coaxial with the radii of the co-operating elements (17, 25). One of the co-operating elements (17) is capable of inward radial movement, and the actuation means (27, 28, 29) operates to prevent that co-operating element's (17) radially inward movement.
