Abstract:
1. An inflation device mechanism for an inflation device for an inflatable article, said inflation device mechanism comprising:— a housing for supporting a container of pressurized fluid and for supporting a piercing device which is displaceable from a retracted position to penetrate the container and allow release pressurized fluid; bias means operable to move the piercing device from said retracted position to penetrate the container, and actuation means comprising co-operating latching elements which, when in an engaged, latched configuration, retain the piercing device in said retracted position; said actuation means being responsive to actuation by either a first or a second control member to allow the co-operating latching elements to disengage and thereby permit the piercing device to advance from said retracted position to penetrate the container under the action of the bias means; said first control member comprising a water sensitive member which surrounds said co-operating latching elements and has a strength sufficient normally to support said co-operating latching elements in an engaged configuration but to allow the co-operating latching elements to disengage when the water sensitive member is reduced in strength by exposure to water, and said second control member comprising a member which surrounds the co-operating latching elements and is removable manually from said position at which it surrounds the co-operating latching elements whereby the co-operating latching elements are allowed to disengage.
