ABSTRACT:
Automatic inflator which inflates gas-inflatable articles by the release of compressed gas from a gas-containing capsule by the piercing of a seal on the capsule. The inflator has an elongated cup-shaped housing having an open rear end and a generally closed front end. The rear end of the housing receives the neck of a compressed gas-containing capsule with the seal on the capsule disposed within the housing. A plunger is disposed adjacent to the forward, generally closed end of the housing, the plunger being adapted to reciprocate longitudinally of the housing. A piercing pin is mounted on the plunger to confront the seal of a capsule mounted on the housing; there is a spring at the forward end of the housing for constantly urging the plunger and the piercing pin thereon longitudinally rearwardly of the housing toward the seal on the capsule, and a releasable blocking device interposed between the plunger and the neck of the capsule to hold the piercing pin spaced from the seal of the capsule. The blocking device includes a water-sensitive member which when wet releases the blocking device so that the spring moves the piercing pin toward the capsule whereby the seal on the capsule is pierced thereby. The inflator is operable both automatically and manually. In the manual operation a support is manually removable laterally from the housing; the plunger, the support, and the blocking device move together toward the capsule when the inflator is operated automatically so that the piercing pin pierces the seal of the capsule.
