The specific embodiment

Below, an embodiment with regard to the float of life jacket of the present invention describes with reference to accompanying drawing.

Fig. 1 is the float that back body sheet is used, and the state of seeing it from face side is shown, and the surface of this float is being installed under the state of life jacket, is positioned at the rear side of life jacket.

This float is installed with buoyancy piece 7 by partly sewing up on the surface of aeration lamellar body 1.By buoyancy piece 7 partly is installed, expose the part on the surface of lamellar body 1.On the other hand, so the inside side of lamellar body 1 is not because covered whole exposing by buoyancy piece 7.But the circumference of lamellar body 1 is by banded cloth 6 lock seamings.

Lamellar body 1 is forming air extractor vent respectively on the two sides in the table that separates predetermined distance along thickness direction, becomes air portion within it, that is, in the table between the two sides along with the direction of thickness direction quadrature on the formation that flows.Specifically, lamellar body 1 is the double knitting material of being weaved into by two Russell's twill knitting machines, as shown in Figure 3, is to be spaced from each other knitting material 2 and the inboard knitting material 3 of table side of predetermined distance by a plurality of connection lead 4 bonded assembly lamellar bodies.That is, two knitting material have a plurality of air extractor vents in the table, and in addition, flexible lamellar body 1 has resiliency by these connection leads 4 on thickness direction.Moreover resiliency can suitably be set by radical or material, the fiber number etc. of the unit area of connection lead 4.

On the other hand, be installed on the lip-deep buoyancy piece 7 of the lamellar body 1 of this formation, form by various plastic foam materials such as polyvinylchloride (PVC) or ethylene vinyl acetate copolymer (EVA) or polystyrene.And buoyancy piece 7 is in the state that roughly whole lining lid 8 covers.Moreover, can use for example jersey as nappe 8.More particularly, after pasting nappe 8 on the two sides in the table of the roughly certain tabular buoyancy piece 7 of thickness, Heat forming on its thickness direction (mold pressing).Whereby, the part of buoyancy piece 7 by conquassation and this part is shaped to thin wall shape, forms the concavo-convex of thickness direction on buoyancy piece 7 on thickness direction.Because on two sides in the table of buoyancy piece 7, pasting nappe 8, so buoyancy piece 7 is with nappe 8 concavo-convex formation.Then, cut off the buoyancy piece 7 that lining lid 8 is covered by part place and become the regulation shape at this thin wall shape.Thereby, cross over the lip portions that full part 7 a that form by thin wall shape form allly at the circumference of buoyancy piece 7, with banded cloth 9 this lip portions lock seaming after, while perhaps lockstitch a border the buoyancy piece 7 of regulation shape is sutured in lamellar body 1.So, buoyancy piece 7 lining lids 8 cover, and formation is concavo-convex on thickness direction, and each is installed with the buoyancy piece 7 that forms like this independently to be spaced from each other the compartment of terrain on the surface of lamellar body 1.Moreover though be installed on lamellar body 1 outside buoyancy piece 7 concavo-convex the becoming, concavo-convex by this, buoyancy piece 7 can easy deformation at the part 7 a places of its thin wall shape.In addition, because float also can be crooked at the position that buoyancy piece 7 is not installed, so float obtains higher applying sense along wearer's physical disfigurement when having worn life jacket.

In addition, though on the surface of lamellar body 1, exist the zone that buoyancy piece 7 is not installed, but this zone is the ventilation zone 5 that is used for discharging the hot gas of the inboard that lodges in float, this ventilation zone 5 is in the float that the back body sheet shown in Fig. 1 is used, except the circumference of lamellar body 1, mainly be located at the part of the substantial middle at the back that is equivalent to the wearer.

Moreover float is installed and removed freely life jacket, therefore, is provided with pair of right and left on the top of float and cares for portion 10, and the bottom of this external float is provided with pair of right and left point button 11.

In addition, about the float of using at the predecessor's sheet shown in Fig. 4, other also were roughly same formations the installation site of different except its outer shape from buoyancy piece 7 etc. were different.

The float that as above, is constituted, though be installed in life jacket by the above-mentioned portion 10 cared for some button 11, under the installing state, with respect to the wearer, outside buoyancy piece is positioned at and lamellar body 1 is positioned at the inboard.And, expose the part on the surface of lamellar body 1 owing to divide ground that buoyancy piece 7 is installed in the upper surface of lamellar body 1, so be ventilation zone 5 with the part on the surface of the lamellar body 1 that exposes, warm air can be discharged to the outside from this ventilation zone 5.At this moment, because lamellar body 1 is a net structure, so guaranteed higher aeration.In addition, because buoyancy piece 7 partly is installed on cancellated lamellar body 1, so compare with the formation that only forms through hole on buoyancy piece, except setting arbitrarily the shape of vent portion, guaranteeing of its area also is easy.

On the other hand, because on the whole the inside of float, be provided with the lamellar body of forming by the knitting material of two-fold 1, so the air at part place beyond the inboard of ventilation zone 5 temporarily enters the inside of lamellar body 1, then, can lamellar body 1 inner along with the direction of thickness direction quadrature on up and down or about flow.Thereby, enter lamellar body 1 in-to-in air in lamellar body 1 inside to above-mentioned ventilation zone 5 one side flow, be discharged to the outside via this ventilation zone 5.So, because the air of the inboard of ventilation zone 5 not only, and the air that is positioned at the inboard of buoyancy piece 7 also discharges from ventilation zone 5 via lamellar body 1, so the result can make all air that are positioned at the float inboard be discharged to the outside from ventilation zone 5.That is, because lamellar body 1 itself brings into play the function of similar exhaust passage the air of float inboard is guided to ventilation zone 5, so also can not obtain higher aeration even do not enlarge the area of ventilation zone 5.Thereby, can easily obtain buoyancy performance and venting capability simultaneously.Particularly, because lamellar body 1 is a double knitting material and only exist connection lead 4 in lamellar body 1 inside, can not obtain higher flowing power so do not hinder flowing of air.And, so stretch repeatedly at thickness direction because of wearer's action owing to lamellar body 1 has resiliency.Thus, flexible by lamellar body 1, can prevent the delay of lamellar body 1 in-to-in air.

Moreover about the number or the configuration of buoyancy piece 7, the perhaps concavo-convex design modification that also can suit that has or not in addition, also can change certainly about formation or thickness, the shape etc. of lamellar body 1.

As mentioned above, owing to partly buoyancy piece is installed so that the part on the surface of aeration lamellar body is exposed, so except can ventilating via the air extractor vent in the lamellar body of the part of exposing, thereby the air that is positioned at the inboard of buoyancy piece also is discharged to the outside in the lamellar body internal flow from the air extractor vent of the above-mentioned part of exposing, and not only can guarantee buoyancy thus but also the aeration when wearing than the easier raising of prior art.
