Abstract: This invention relates to a manually operated inflator for inflatable articles such as life vests and the like. Such inflator, which is typically employed with an inflatable life vest, is operated by pulling on a lanyard attached to a lever which has integrally attached thereto a cam which forces a piercing pin against the seal of the CO.sub.2 capsule. In accordance with the invention the hole in the cam which was formerly employed to receive a pivot pin in the prior construction of the inflator has been replaced by a notch which is so disposed angularly with respect to the active surface of the cam that the root of the notch provides for a positive thrusting engagement between it and the pivot pin throughout the angle of rotation of the cam which is necessary to effect the piercing of the seal of the capsule, but provides for the ready escape of the lever end cam from the body of the inflator once the capsule seal has been pierced.

Abstract: Dual firing inflator for an inflatable article. A first gas containing capsule is pierced by energy supplied either manually or by a compressed spring of the like and the gas from the pierced first capsule powers a second piercing pin which pierces a second gas containing capsule. This reduces the amount of externally applied energy which is necessary to operate the inflator while supplying the inflatable article with an amount of gas which is twice that contained in capsules which are normally used with inflators of the same general type.

Abstract: An emergency rescue assembly comprising a container attachable to a boat so as to overhang the water, with an automatically inflatable location or flotation device stored in the container. The container is readily opened by a pull on a release so that the device falls into the water and automatically inflates.

Abstract: A vacuum packaged flotation device is provided comprising the combination of an inflatable flotation device, equipment for inflating the flotation device which comprises a valve, a container for holding an inflating medium and the inflating medium, and a sealed vacuum package containing the inflatable flotation device and the equipment for inflating same, which is provided with at least one device for automatically or manually, actuating the inflation of the flotation device; wherein the inflation of the flotation device is triggered by a pull force which acts either automatically or manually on one or more connecting lanyards which are attached at one end to the actuation device, which lanyards extend through the vacuum package in such a manner as to preserve the integrity of the vacuum seal, while at the same time allowing the manual triggering of the actuation device with the exertion of a pull force of no more than about 7-15 Kg from any of a plurality of angles.

Abstract: A buoyancy compensator in the form of an air inflatable vest wearable generally about the user's chest and having a back portion encircling the user-3 s back or neck, includes an air pressure release mechanism on the vest back portion. The air pressure release mechanism may include a tube arranged to extend upwardly when the user is oriented in the normal prone swimming position. A valve located near the upper, open end of the tube may be operable by the user through a remote valve operator to release air pressure from the compensator enclosure. The remote valve operator may be positioned on the air inflation hose adjacent to the air inflation hose valve to enable one handed inflation and delfation. In one advantageous embodiment the remote valve operator is connected to the valve by a strand encased within a sleeve so that manipulation of the operator opens the valve to release air pressure.

The bladder may be inflated either by a gas-powered valve assembly or by exhalation of the user into an oral valve. Fasteners are provided to store the crotch portion when not in use so that the jacket can be used for routine as well as emergency wear.

Abstract: A life belt comprising a ring shaped tubular body which incorporates a device for fastening the tubular body around a waist of a person, a compressed gas containing capsule connected to the tubular body and an actuator for releasing the compressed gas into the tubular body to inflate the tubular body, in which the tubular body has a first portion and a second portion. The second portion is obliquely bent downward at about 120.degree.-160.degree. relative to the first portion.

Abstract: A strip-like body member in the form of a belt has one or more slits extending through it. A flat air-tight expandable bladder extends along the rear surface of the body member and is enclosed between such body member and a backing strip. A pocket is provided on the body member for removably holding a gas cartridge, and such cartridge is associated with an actuator arranged to release the contents of the cartridge. The cartridge communicates with the bladder and when opened by a pull line connected to the actuator, the bladder expands forwardly through the slits to form a buoyant life preserver. The body member is dimensioned and arranged to be passed through the conventional trouser belt loops so as to serve the dual purpose of holding up trousers and to be available as a life preserver when needed. The pull line is held normally in place by a releasable hold-down connector so as to be out of the way until needed.
