Abstract

The present invention relates to a kind of inflated article of new structure.It is made of double-decker one internal layer and skin.Internal layer adopts thin thin closely knit base cloth, single face to apply thin air-tightness coating material and make, and is processed into the simple geometric shape, mainly plays airtight effect.The high-intensity textile material of outer employing forms according to concrete purposes design, cutting, sewing.The outer main effects such as figuration, protection connection that play.The present invention is simple for production, and the ingenious combination by ectonexine has fundamentally changed numerous and diverse traditional handicraft, has improved the capacity rating of inflated article, and has reduced cost.

Description

The inflated article of new structure

The present invention relates to a kind of double-deck inflated article that has.

Up to now, many inflated articles (as air inflation raft, rubber boat etc.) all adopt thick rubber fabric could make successfully through multiple working procedures such as cutting, stickup, sulfurations basically.There are certain problem in this goods and manufacture method.The one, adhesive plaster is not only thick but also heavy, makes trouble.Especially large-scale inflated article, inflation back adhesive plaster is subjected to tension force big, so the necessary brute force of adhesive plaster is high, air-tightness is good.So to the powerful height that requires of the base cloth of adhesive plaster.Cause like this that base cloth is thicker, spread is big.Spread just need take blade coating to add the photoresist coating process of calendering greatly, makes manufacturing process complicated.Because the high and bonding annex of air-tightness requirement is needed two-sided gluing, further cause the thickness of adhesive plaster and weight to increase in addition, make complexity, production process is many, and efficient is low, cost is high.The 2nd, the complex forming technology of inflated article.Many inflated articles, particularly large-scale inflated article such as liferaft etc., planform is special, thereby forming process is also complicated.Comprise the bonding operation of a large amount of craft in the forming process, require sternly, speed is slow, and time-consuming bothersome, production efficiency is low, the labour cost height.

Purpose of the present invention is the deficiency in the above-mentioned prior art and design-calculated new structure inflated article just.

The objective of the invention is to reach: adopt double-deck inflated article, be divided into internal layer with outer by following measures.Internal layer is an air-retaining liner; adopt the good materials processing of air-tightness to become simple geometric shapes such as tubular or ring-type; skin is figuration layer and protective cover; adopt high-intensity textile material to make; purposes figuration according to inflated article; and internal layer played protection and interconnect function, and the chief component of inflated article played interconnect function.

With the liferaft casehistory: the double-decker of inflated article-liferaft is meant at the bottom of the floating tire, gas column, raft of raft etc. that inflatable structure is made of internal layer and skin.Internal layer adopts thinner, closely knit base cloth single face to apply thin air-tightness coating and makes.Coating material can be TPUE, rubber or other suitable gastight material.Owing to be the slim adhesive plaster of single face, thereby coating technique is easy, and production efficiency height, cost are low.Internal layer is made the simple geometric shape, as tubular, ring-type etc.Internal layer mainly plays airtight effect.

The high-intensity textiles of outer employing is made, as bright and beautiful silk, polyester silk or other suitable textile material.Cladding material is without gluing.Outer field effect is figuration, protection and is connected.The implication of figuration is that internal layer is only made the simple geometric shape, and the shape after the goods inflation is given by skin.The implication of protection is that the suffered tension force major part of inflation back internal layer reaches skin, and the suffered tension force of internal layer descends significantly, be that skin is subjected to power earlier and bears wherein major part equally when being subjected to external force, thereby skin plays a protective role to internal layer.The bonded assembly implication be between the chief component of inflated article and on many annexes can couple together by skin.Outer field planform needs according to purposes design processing.Such as becoming equilateral polygon after the floating tire inflation.So outer just by equilateral polygon design, cutting, make, be enclosed within on the internal layer.Toward the internal layer inflation time,, promptly form designed equilateral polygon after the inflation owing to be subjected to outer shape restriction.Owing to outer adopt sewing tech, thereby process easyly, rapid, improved production efficiency greatly.

The present invention is further described below in conjunction with accompanying drawing:

Fig. 1 is the floating tire of the embodiment-octagon raft of inflated article.

Fig. 2 is for making the raw material scheme drawing of floating tire.

Fig. 3 is the part scheme drawing of floating tire.

Description of drawings: 1-skin, 2-internal layer.

Each limit of floating tire of octagon raft is cylindrical, and diameter is d, launches the long π d that is, the length of side is H.Cut out a cloth, length＞8H, wide＞π d draws two curves every H.This curve is that diameter is the octagonal cylinder column intersection of d, is mutually symmetrical as Fig. 2.Along these two curves that cloth is stitched together, promptly form after the expansion and turn round as Fig. 3.Make the formation octagon according to said method.Again above-mentioned octagon is seamed into tubular.Internal layer is put into octagon tubular skin, the two-port butt joint, bonding one-tenth is circular.Skin seals with methods such as bonding or sewing again.By air inlet valve internal layer is inflated.Inflation back internal layer is close to skin and is formed octagonal floating tire, as Fig. 1.

Annex on the internal layer such as air inlet valve, safety valve etc. can adopt adhesion agent that they are bonded on the internal layer, use the adhesive plaster bonding and reinforcing when needing reinforcement.The come-up tire and the tire of floating downward, float downward tire with at the bottom of the raft and gas column etc. be connected etc. can be by separately skin with the lockstitch connection or to stick with glue agent bonding.With on the corresponding skin of these accessory position as need perforate, also need take reinforcement measure, become weak link with the protection internal layer and when preventing to inflate.

The present invention gives full play to the airtight effect of internal layer, outer field figuration, protection and interconnect function by double-deck ingenious combination.Fundamentally change numerous and diverse traditional processing technology, improved labor efficiency greatly, reduced productive costs.

Claims

1, a kind of inflated article of new structure is characterized in that this inflated article is a double-decker.

2, inflated article as claimed in claim 1 is characterized in that said double-decker is divided into internal layer with outer, and internal layer is an air-retaining liner, adopts the good material of air-tightness to make, and can be processed into simple geometric shapes such as tubular or ring-type; Skin is figuration layer and protective cover, adopts high-intensity textile material to make, according to the purposes figuration of inflated article, and to internal layer rise the protection and interconnect function, also can play interconnect function to the chief component of inflated article.

3, inflated article as claimed in claim 2, it is characterized in that so-called figuration be meant profile after the inflated article inflation be by cladding material through cutting, give after making.
