ABSTRACT:
This invention concerns a new type of Mini-Collar which can be worn continuously around the neck, its very small, very light, not bulky, comfortable, and brought into use rapidly and very easily. The Collar is formed from two symmetrically almost identical, independent major elements. The invention provides for each major element to be independent and to include apparatus to deliver compressed air, to inflate an expansible envelope providing support for an individual in the water. The inflatable assembly of each independent element comprises essentially a frame shaped as a semicircle which is a container frame filled with compressed air. Cooperation between the two elements provides that each one forms at one end, half of a hinge which secured to each other will form a solid coupling element. At the other end of the frame container, each element has a terminal head equipped with apparatus to lock the Mini-Collar around the neck and in the event of an emergency to deliver the compressed air from the frame container into the inflatable envelope. The inflatable assembly of both independent elements will be simultaneously activated by a control member, when the individual who carries the Mini-Collar will activate the control member.
