Automatic flotation release system
First Claim
1. In an emergency locating unit adapted to be carried on a vehicle, said unit having an inflatable aerial device disposed in a storage condition, inflating means for launching said aerial device into the air and releasable trigger means for triggering operation of said inflating means, the improvement residing in a launching guide assembly, comprising removable closure means engageable with the trigger means for preventing operation thereof, flotation positioning means mounted on the inflating means for operative orientation thereof during said launching of the aerial device, breakaway housing means engageable with the closure means and the positioning means prior to said launching of the aerial device for holding the launching guide assembly operatively assembled and the aerial device protectively enclosed therein in the storage condition, said closure means comprising a pair of end covers axially spaced from each other by the flotation positioning means and the breakaway housing means.

Abstract
An aerial lift balloon and signalling components attached thereto are stored within a closure member held assembled with a breakaway housing to form a package storing an inflating device for the balloon. Removal of the closure member initiates inflation of the balloon and operation of the signalling components, while removal of an end cover of the package permits separation of the breakaway housing enabling the positioning of the inflating device by a flotation collar portion of the package for aerial launching of the balloon with the signalling components suspended therefrom.

- 1. In an emergency locating unit adapted to be carried on a vehicle, said unit having an inflatable aerial device disposed in a storage condition, inflating means for launching said aerial device into the air and releasable trigger means for triggering operation of said inflating means, the improvement residing in a launching guide assembly, comprising removable closure means engageable with the trigger means for preventing operation thereof, flotation positioning means mounted on the inflating means for operative orientation thereof during said launching of the aerial device, breakaway housing means engageable with the closure means and the positioning means prior to said launching of the aerial device for holding the launching guide assembly operatively assembled and the aerial device protectively enclosed therein in the storage condition, said closure means comprising a pair of end covers axially spaced from each other by the flotation positioning means and the breakaway housing means.
- 6. In an emergency locating unit adapted to be carried on a marine craft, said unit having an inflatable serial device disposed in a storage condition, inflating means for launching said aerial device, and releasable trigger means for triggering operation of said inflating means, the improvement residing in a launching guide assembly, comprising removable closure means engageable with the trigger means for preventing operation thereof, positioning means mounted on the inflating means for operative orientation thereof during said launching of the aerial device, breakaway housing means engageable with the closure means and the positioning means prior to inflation of the aerial device for holding the launching guide assembly operatively assembled and the aerial device protectively enclosed therein in the storage condition, signalling means retained in a standby condition within the closure means, means responsive to separation of the closure means from the aerial device for triggering operation of the signalling means, and means coupling the aerial device to the signalling means for suspension from the aerial device when launched, said positioning means being a flotation collar.

10. In an emergency locating unit adapted to be carried on a marine craft, and having an inflatable aerial device disposed in a storage condition, inflating means for launching said aerial device into the air, and releasable trigger means for triggering operation of said inflating means, the improvement residing in a launching guide assembly, comprising removable closure means engageable with the releasable trigger means for preventing operation thereof, signalling means retained in a standby condition within the closure means, means responsive to separation of the closure means from the inflating means for triggering operation of the signalling means, means coupling the aerial device to the signalling means for suspension from the aerial device when launched to provide a locating signal and flotation means mounted on the inflating means for floatingly supporting the inflating means in the water following said separation of the closure means from the inflating means.
- 11. In a unit having an inflatable aerial device in a storage condition, inflating means for launching said aerial device into the air, and releasable trigger means for triggering operation of said inflating means, the improvement residing in a launching guide assembly, comprising removable closure means engageable with the releasable trigger means for preventing operation thereof, breakaway housing means engageable with the closure means to form an enclosure within which the aerial device is stored in the storage condition thereof and the inflating means is held assembled prior to said launching, and means responsive to removal of the closure means from the launching guide assembly for causing separation of the breakaway housing means from the inflating means.

15. In combination with an emergency unit adapted to be carried on a craft for signalling the location thereof following submersion within a body of water, said unit having an inflatable aerial device disposed in a storage condition, inflating means for launching said aerial device into the air, and releasable trigger means for triggering operation of said inflating means, the immprovement residing in a launching guide assembly, comprising removable closure means engageable with the releasable trigger means for preventing triggering operation thereof, flotation means mounted on the inflating means for floating support thereof in a launching position during said launching of the aerial device, separable housing means held assembled by the closure means and the flotation means for protectively storing the inflating means and the aerial device prior to said launching thereof and means responsive to said submersion within the water for removing the closure means from the launching guide assembly to disengage the releasable trigger means and permit separation of the separable housing means from the inflating means, whereby the trigger means triggers operation of the inflating means to launch the aerial device from the launching position into the air under buoyancy forces.
- 16. In a flotation type of kit for locating a craft that has submerged into a body of water, which comprises a disintegrating form of housing for storage of the kit adapted for removable mounting on the craft, means for holding said housing on the craft, a float assembly including an inflatable device and a high pressure gas container connected thereto and adapted for storage within said housing, cable means connecting said float assembly to said craft, and gas release means positioned between said inflatable device and the gas container for inflation of the inflatable device upon release and unfolding thereof from the housing, the improvement residing in said housing having separable means secured to the gas container for floating support thereof in a launching position, removable closure means operatively connected to said housing, and means connecting the housing to the craft for resisting buoyancy forces exerted on the housing in response to submergence of the craft to cause removal of the closure means and disintegration of the housing and separation of said separable means therefrom with the gas container, whereby the inflatable device is launched into the air in response to said inflation thereof by the gas container in the launching position.
