Abstract
The utility model relates to an inherent-buoyancy-type life jacket. A body in a style of a vest comprises a left front inherent-buoyancy-type garment piece, a right front inherent-buoyancy garment piece and a back inherent-buoyancy garment piece, which are composed of two front garment piece coated foam inner cores and a back garment piece coated foam inner core respectively, the foam inner cores are made of flexible closed-cell foam plastic by one-step compression molding, and a zipper is transversely arranged in the middle of the two front garment pieces and the back garment piece. The design convention that the traditional foam plastic is cut into foam pieces to be coated with fabric to be sewn into a life jacket with corner and edges is broken through by providing the inherent-buoyancy-type life jacket, foam buoyant material meeting the ergonomic characteristics is obtained by one-step compression molding, and accordingly the problem that the traditional foam life jacket is poor in body fitting is improved greatly and the problem that foam buoyant material is less easy to replace is solved.
Description
Technical field
The utility model relates to a kind of inherent buoyancy formula life jacket, the replaceable buoyant material of this life jacket, and buoyant material is once molding formed and the corner is mellow and full, and is comfortable and easy to wear fit, uses this life jacket can be convenient to carry out in every water movable.
Background technology
Different according to buoyant material, life jacket can be divided into inherent buoyancy formula life jacket and inflatable life jacket.Wherein inherent buoyancy formula life jacket is that buoyant material is made mainly with block foam, and part military life-saving clothing can adopt the fiber assembly buoyant materials such as kapok to make.In order to guarantee essential buoyancy, thicker as the block foam general thickness of buoyant material, reaching this thickness more than the 20mm or behind the multilayer build-up at least; And traditional life jacket method for making be with block foam by being cut into preliminary dimension, then coat fabric and make.So just caused the foamed plastic edge thickness after the cutting also at least more than 20mm, just become block, bulging after being sewn into life jacket, can imagine the situation of the cystosepiment that human body surface applying one deck 20mm is thick, cause foam life jacket and human body not to be fitted, be difficult to squat down, bend over or other action.In order to solve this difficult problem, usually adopt buoyant mass is divided into different little buoyant mass, then one makes is convenient to activity so slightly, but the foamed plastic buoyant mass still can not well be fitted with human body.
Simultaneously, owing to therefore the mode of foamed plastic buoyant mass by sewing is covered by in the outer shell fabric,, when the phenomenons such as foamed buoyant material has damage, scratches, fracture, even miscellaneous part all stands intact, also must change whole life jacket, cause unnecessary waste.Simultaneously, be unfavorable for the maintaining of life jacket.
The utility model content
The purpose of this utility model is to provide a kind of fit property fabulous foamed plastic lifejacket, this life jacket is fit, and property is good, after the user is wearing this life jacket, can bend over easily, squat down, the action such as Qu Ti, and foam buoyancy inner core can be taken out, maintain and change, prolong the service life of life jacket, reduce the cost.
The purpose of this utility model is achieved in that
A kind of inherent buoyancy formula life jacket, main body is the vest style, comprise body inherent buoyancy garment piece behind left and right two predecessor's inherent buoyancy garment pieces and, described two predecessor's inherent buoyancy garment pieces and rear body inherent buoyancy garment piece coat foam core by two front body panel and rear body piece respectively and consist of, described foam core is once molding formed flexible closed cell foamed plastic, and the centre of described two front body panel and rear body piece is provided with slide fastener.
Described flexible closed cell foamed plastic is rubber plastic blend expanded material or the pure plastic foam materials such as government rubber/polyvinylchloride (NBR/PVC), ethylene propylene diene rubber/plastic of poly vinyl acetate (EPDM/EVA), polyurethane (PU), polyethylene (PE), polyvinylchloride (PVC), ethylene propylene diene rubber (EPDM), plastic of poly vinyl acetate (EVA), preferred NBR/PVC flexible closed cell foamed plastic.
Described foam core is two front body panel and rear body piece (life jacket garment piece) shape, and variable thickness causes everywhere, and more near the edge, thickness is attenuate gradually, and the applying human body meets the ergonomics feature.
Described slide fastener is horizontally set at the reverse side midway location of two front body panel and rear body piece, for having the common slide fastener of pull head auto-lock function, is convenient to place and take out the buoyancy inner core.
One of them front body panel such as right garment piece, is equipped with zufolo, and two front body panel and rear body piece all are equipped with the retroreflecting film.
Described life jacket also is equipped with waistband, and the positive and negative two sides waist of described two front body panel and rear body piece all arranges the waistband loop, can positive and negatively wear.
The utility model life jacket has been broken through the conventional foam synthetic life jacket by the cutting block foam and has been sewn into the designing and making thinking of life jacket, adopt the flexible closed cell foamed plastic of once molding formed technique preparation as buoyant material, and designed slide fastener and be convenient to pick and place this foam buoyancy inner core, solved the difficult problem that the fit property of conventional foam synthetic life jacket is poor, buoyant material is difficult to change.
Compared with the prior art the utility model has following advantage:
1, the utility model has adopted once molding formed flexible foam buoyancy inner core, and the marginal portion is by thick gradually attenuate, and fit property is good, and after the user puts on, and human body extremely fits, and movable convenient.
2, the foam buoyancy inner cores such as NBR/PVC of the compression molding of the utility model employing are a kind of rubber plastic blend expanded materials, have the lightweight of resilient flexible and the plastics of rubber concurrently, and this has improved the fit property of wearing of life jacket greatly.
3, garment piece middle part before and after the utility model, laterally all be provided with slide fastener, be convenient to place and take out foam buoyancy inner core, can be convenient to damaged condition that the user checks foam buoyancy inner core, be convenient to maintaining and change the buoyancy inner core, greatly save the cost of collective's working service life jacket.
