Abstract

Abstract The present invention relates to a life float. The life float comprises a stretching capsule and a string or cord starting at the ends thereof, arranged to pass around over a shoulder and under an arm. The watertight capsule consists of a part resembling a test tube and a cap in the shape of a test tube bottom. The inside of the capsule includes a float to be filled, a small gas capsule and a pricking mechanism therebetween for the gas capsule, a pressure reducer, an air vale, and a whistle. The capsule is to be placed close to the chest so that a person can reach it with his hands. When needing the float, the person catches the capsule and pushes it further off from his/her body. Hereby, the cap of the watertight capsule opens, owing to the pulling movement caused by thread 1, and the threads pull the entire float out. The rest of the inside remains within the capsule. As the float is extracted, the mechanism pricks the gas container, thus making the float to be filled. The fill-in gas passes through the loud whistle. When the float is filled, the string on the shoulder can also be passed under the arm.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 216 words
A life float, comprising: a small capsule with a removable end, said capsule having therein a fill-in float, a gas inflating means coupled to said fill-in float for inflating said fill-in float, wherein said gas inflating means comprises a gas container having a sealing film which in use is burst by a pricking mechanism whereby gas is enabled to flow to said fill-an float, and a triggering means for triggering said gas inflating means to inflate .said fill-in float, said triggering means comprising said pricking mechanism and said triggering means located between the gas container and the float; and a link means coupled to and extended through said capsule forming a circular link such that a predetermined pressure exerted on said link means pulls said fill-in float from said capsule and triggers said triggering means thereby causing said fill-in float to be inflated, said link means configured such that in use said link means can encircle a user by being passed over a shoulder and under one arm behind the back to keep said capsule close to the chest of a user so that said capsule can be reached with a hand of the user and further serving as a fastening link passed under the arms to keep the inflated fill-in float close to the chest.
Claim 2
Dependent Claim 216 words
A life float, comprising: a small capsule with a removable end, said capsule having therein a fill-in float, a gas inflating means coupled to said fill-in float for inflating said fill-in float, wherein said gas inflating means comprises a gas container having a sealing film which in use is burst by a pricking mechanism whereby gas is enabled to flow to said fill-an float, and a triggering means for triggering said gas inflating means to inflate .said fill-in float, said triggering means comprising said pricking mechanism and said triggering means located between the gas container and the float; and a link means coupled to and extended through said capsule forming a circular link such that a predetermined pressure exerted on said link means pulls said fill-in float from said capsule and triggers said triggering means thereby causing said fill-in float to be inflated, said link means configured such that in use said link means can encircle a user by being passed over a shoulder and under one arm behind the back to keep said capsule close to the chest of a user so that said capsule can be reached with a hand of the user and further serving as a fastening link passed under the arms to keep the inflated fill-in float close to the chest.
Claim 3
Dependent Claim 28 words
Life float according to claim 1, characterized in that associated with the gas container a loud whistle is provided, making a great noise when the gas flows therethrough.
Claim 4
Dependent Claim 42 words
Life float according to claim 2, characterized in that within the capsule is provided a pull-out mechanism for the capsule, to pull the inside of the capsule so far out that the float is completely discharged before it is filled with gas.
Claim 5
Dependent Claim 27 words
Life float according to claim 3, characterized in that the pricking of the fill-in gas container is performed at a distance from the body of a user.
