Abstract
Abstract A combined swimming aid and lifesaving device in which a buoyant harness for encircling the swimmer's torso comprises a plurality of releasably interconnected portions for selective use of one or more parts of the harness to obtain desired buoyancy, and a plurality of separate inflatable buoyant devices are releasably attached to the harness at spaced locations thereon to impart greater or lesser buoyancy to the device for providing desired buoyant support to the swimmer to maintain the swimmer in horizontal position in the water. Attaching points are on the harness for securing a lifeline thereto, and the inflatable buoyant devices remain slack when inflated so that they are able to undulate during use to reduce drag through the water.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
108 words
A combined swimming aid and lifesaving device, comprising: a torso-encircling buoyant harness means for releasable attachment to the body of a swimmer to impart substantially neutral equilibrium to the swimmer; a plurality of separate inflatable buoyant means carried by the harness for selective inflation to impart desired buoyancy to the swimmer; and said buoyant means remaining at least partially slack when inflated and having a narrower leading edge than trailing edge, and having accordian or bellows-like pleats or folds along the leading and trailing edges, whereby the buoyant means presents a streamlined configuration for passage through water and said buoyant means may undulate to reduce drag during use.
Claim 2
Dependent Claim
108 words
A combined swimming aid and lifesaving device, comprising: a torso-encircling buoyant harness means for releasable attachment to the body of a swimmer to impart substantially neutral equilibrium to the swimmer; a plurality of separate inflatable buoyant means carried by the harness for selective inflation to impart desired buoyancy to the swimmer; and said buoyant means remaining at least partially slack when inflated and having a narrower leading edge than trailing edge, and having accordian or bellows-like pleats or folds along the leading and trailing edges, whereby the buoyant means presents a streamlined configuration for passage through water and said buoyant means may undulate to reduce drag during use.
Claim 3
Dependent Claim
44 words
A combined swimming aid and lifesaving device as in claim 1, wherein: the harness means comprises a plurality of separable parts for selective application and removal to the body of the swimmer to adjust the buoyancy imparted to the swimmer by the harness means.
Claim 4
Dependent Claim
67 words
A combined swimming aid and lifesaving device as in claim 2, wherein: the separable parts of the harness means include an upper portion for encircling the chest area of the swimmer, a midportion for encircling the waist area of the swimmer, and a lower portion for encircling the pelvic area of the swimmer, the upper portion, midportion and lower portion being interconnected but separable from one another.
Claim 5
Dependent Claim
23 words
A combined swimming aid and lifesaving device as in claim 3, wherein: the inflatable buoyant devices are releasably attached to the harness means.
Claim 6
Dependent Claim
22 words
A combined swimming aid and lifesaving device as in claim 3, wherein: the inflatable buoyant devices are integral with the harness means.
Claim 7
Dependent Claim
25 words
A combined swimming aid and lifesaving device as in one of claims 1, wherein: the inflatable buoyant devices are releasably attached to the harness means.
