The present invention relates to a floating garment.
More particularly, the invention concerns garments manufactured by a floating multilayer textile, able supporting and upturning the body in such a way that face is faced upward, as provided by exiting rules.
The present invention can be particularly applied to either to work garments for water environments (industrial fishing, sport fishing, water activities, first aid, ecc.), and to other activities carried out in said environments.
At present, those making activities, such as work, sport or fun, close or on water environments wear floating elements, either jacket, ring buoy or like. Said elements permit floating in case of fall into the water, preventing drowning risks. Particularly, in case of work activities, it is compulsory wearing on said elements, permitting upturning the body so as the face is faced upward. Said floating elements must fulfill ISO 12402 standards.
However, said floating elements are rather bulky and heavy, making it more difficult carrying out the activities. Just due to the bulkiness and weight of said elements, many people decides not to wear on them to move more freely. This clearly involves serious risks in case of falling into the water. Further, being it difficult providing accidental events, it is difficult wearing them at proper time.
Therefore, it is object of the present invention that of manufacturing floating garments which are also light and with reduced dimensions, permitting advantageously easing activities in water environments.
Further object of the invention is that of obtaining floating garments able upturning the body in case of fall into the water, so as to have the face faced upward.
Another object of the present invention is that of preventing necessity of wearing secondary safety elements, which are easily forgotten.
It is object of the present invention a garment made up of floating multilayer textile, said garment (6) comprising a central portion (61) to support the trunk, a top portion (60) to support the neck, said multilayer textile (1) comprising at least one outer sheet, at least one intermediate sheet and at least one inner sheet, said garment being characterized in that said at least one intermediate sheet of said floating multilayer textile consists of a multilayer membrane, in particular made ip of closed-cell polyethylene, wherein at least 50% of said membrane is made up of air, in that said textile is provided with between 3 g to 5 g of said intermediate sheet for each 1 kg of weight to support in water, and in that the membrane material provided for the intermediate sheet at said central portion of said garment, is distributed so that between 60% and 80% is arranged in the front side of said central portion and between 40% and 20% is arranged in the rear side of said central portion.
Further according to the invention, said membrane material provided for said intermediate sheet at said central portion of said garment, can be distributed so that the 70% is arranged in said front part of said central portion and the 30% is arranged in said rear part of said central portion.
Always according to the invention, said membrane material provided for said intermediate sheet can be equally distributed at said top portion of said garment (6).
In particular, according to the invention, said garment can further comprise a lower portion to support the legs and the membrane material provided for said intermediate sheet can be equally distributed at said lower portion of said garment.
Further, according to the invention, each layer of said membrane of said intermediate sheet of said textile can have a thickness of at least 0.6 mm.
Still according to the invention, at least 50% of said membrane of said intermediate sheet of said textile can be made of air, and preferably over 97% of said membrane can be made of air.
Always according to the invention, said membrane of said intermediate sheet of said textile can have buoyancy features equivalent to 63N, preferably it can have thermal insulation features equivalent to 0.04 W/m-k and even more preferably 1 m2 of said membrane can have a weight of 16 g.
Furthermore according to the invention, said outer sheet and/or said inner sheet of said textile can be made up of hydro-breathable or refractive material, or flame retardant material, or windproof material, or waterproof material.
Finally, according to the invention, said inner sheet of said textile can be made up of lining.
The invention will be now described for illustrative but not limitative purposes with particular reference to the figures of the enclosed drawings, wherein:
A membrane thick 0.6 mm is available on the market, comprised of closed cell polyethylene comprising more than 97% of air. Thanks to its cellular structure composition, said membrane has optimum floating (63N), thermal insulation (0.04 W/m-K) and lightness (16 g/m2) features.
Present invention suggests realization of a floating multilayer textile 1 using said membrane an intermediate sheet 3, placing the membrane between an outer sheet 2 and an inner sheet 4, comprised of different materials. A first embodiment is shown in
As already said, type of selected material for outer sheet 2 and inner sheet 4 depends on final use of the floating multilayer textile 1. They can be refractive materials, or flame retardant materials, or windproof materials, or waterproof materials, ecc..
Said floating multilayer textile 1 has advantageous floating features, and thus it can be used for manufacturing garments, to be preferably close to water environments.
Particularly, according to the invention, 5 g of membrane intermediate sheets 3 distributed into the garment every 1 kg of weight of the user are necessary for supporting the body.
Generally speaking, membrane can give floating function placing 3 g for every 1 kg to be supported along the garment 6. In case 4 g of membrane for each kg are provided, good safety condition can be obtained.
Furthermore, in order to ensure an advantageous support and upturning of body in position provided by rules, i.e. with head faced upward, it is necessary a different distribution of membrane intermediate sheets 3.
Making reference to
Said distribution of membrane as intermediate sheet 3 along the garment 6 permits upturning the body in case of fall within the water (regardless it is salty or fresh water), so as to have the face faced toward the sky and supporting the body with an inclination of about 45°.
Said general rules can be applied to different types of garments, some embodiments of which are shown in
The present invention has been described for illustrative, but not limitative purposes, according to its preferred embodiments, but it is understood that variations and/or modifications can be introduced by those skilled in the art without departing from the relevant scope, as defined in the enclosed claims.
