CN2313468Y - Self aerating air-cushion - Google Patents

Abstract

The utility model relates to a self aerating air cushion, which is composed of an air bag body, and a valve, wherein the air bag body is composed of lamellar structures formed by fabric surfacing material with good strength and air tightness and PVC synthetics composite membrane which are compounded, and soft foam fillers are filled in the air bag body. In this way, the air bag type cushion which can naturally spread and recover into the original cushion by means of the soft foam fillers after pressed is formed. The utility model has the advantages of simple structure, convenient operation, easy carrying for going out, large use range, etc., and besides users have no need of preparing a pump and blowing.

Description

The self-resetting type inflatable mattress

But the utility model relates to a kind of inflatable mattress of pressure-bearing, especially a kind of can runback, exempt from the inflatable air bag mat, comprise mattress and seat cushion etc.

At present the mat that generally uses of people has two kinds of hard packing and cushions.With regard to hard packing, mainly contain the bamboo seat cushion that uses summer or mattress etc.; And cushion is based on the air bag mat, but because the bearing capacity of conventional air bag mat is generally relatively poor, and the fastness of its air-tightness and mat lining is had relatively high expectations, so be subjected to its service life above-mentionedly to influence greatlyyer, often the air bag mat is to make back cushion or bolster.Along with science and technology development, people make the material of air bag cushion select to have had new breakthrough for the development and application of new material, but inconvenience is still felt in the use of air bag mat, because the air bag mat can power just the user carry, gas in the air bag mat is bled off the back just can be folded up mat, dwindled the volume of air bag mat widely, but use this air bag mat must be with an inflator fully, so that can inflate air in the air bag mat with inflator outside, after being sticked out, it can use.Obviously, the maximum deficiency of the inflatable mattress of this belt transect charge valve existence is to need inflator of configuration.Inflating air to the air bag mat with inflator mainly is at large-scale inflatable mattress and blind, for some small-sized air bag mats, people often blow facing to charge valve with mouth and realize, this not the exempt from customs examination user bring antihygienic disadvantage, and often be difficult for gas abundance in this way with the air bag mat.

The purpose of this utility model is in order to overcome the deficiency of above-mentioned existence, can return to normal automatically and with fully inflated self-resetting type inflatable mattress in the air bag mat and provide a kind of.

The purpose of this utility model is to finish by following technical solution, it mainly by surface layer up and down around the bonding pneumatophore that forms and the air valve installed on it form, in airtight air bag, lay the flexible foam filler, utilize the compressibility of flexible foam filler to reach from renaturation, but make air bag exhaust under external force, and after external force disappears normally air inlet to return to normal, i.e. sufficient gas state.

For increasing the fastness and the air-tightness of surface layer up and down, the utility model adopts composite cover, and it is composited by fabric lining and PVC synthetics composite membrane.

The utility model is fixed with the air valve of turnover gas on described surface layer, this air valve comprises the flat-shaped valve seat that is fixed on the surface layer, spool that is connected on the valve seat and the valve gap that is screwed in together, dispose valve pad above the spool, and valve pad is placed on the turnover gas access opening of spool, valve gap spins by screw thread, and the jacking block roof pressure of its inner end is on valve pad.

Description of drawings is as follows:

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the utility model contour structures schematic diagram.

Fig. 3 is an air valve structure schematic diagram of the present utility model.

To be described in detail the utility model by accompanying drawing below: Fig. 1, the utility model mainly are made up of air bag 1 and the air valve 2 that fixedly mounts on it.Pneumatophore 1 by surface layer 3,4 up and down around constitute after bonding, lay flexible foam filler 5 in it, this flexible foam filler 5 almost fills up pneumatophore 1 totality cavity volume, elder generation is with after surface layer clads soft foam stuffing 5 up and down in manufacturing process, carry out adhesion all around with sizing material again, have certain three-dimensional shape with this, both can compress with reduced volume, the flexible foam filler 5 that can return to normal voluntarily again is included in the pneumatophore.Be illustrated in figure 2 as rectangular Inflated pillow mattress, surface layer 3,4 is contained within inner oblong-shaped flexible foam filler 5 fully about it, and its normality is an oblong-shaped.The utility model is at the bonding seam crossing of surface layer up and down 3, the 4 glue air valve 2 of ining succession also, the structure of this air valve as shown in Figure 3, it includes the flat-shaped valve seat 6 that is fixed on pneumatophore surface layer seam crossing about in the of 1, the spool 7 (or being made of one) that is connected on the valve seat 6, and the valve gap 8 that is screwed in spool.On the blow vent of spool 7, dispose rubber valve pad 9, and this valve pad 9 just covers on blow vent, valve gap 8 spins by screw thread on the spool 7, and its inner end is provided with jacking block 10, when valve gap 8 is tightened on the spool 7, these jacking block 10 roof pressures and bury the passage 11 of spool 7 on valve pad 9, realize closing of air valve 2.Mat described in the utility model has comprised various mats such as seat cushion, mattress, back cushion.The bed of cloth of above-described surface layer up and down 3,4 its outsides comprises nylon cloth, cotton and chemical fabric, and described flexible foam filler comprises the foam stuffing that ethene, polyurethane and polyvinyl chloride are made through the foaming manufacture craft.The also available commercially available conventional air valve of described air valve replaces.

The utility model compared with prior art has simple in structurely, easy to use, neither needs to provide for oneself and beats Inflator, avoided going to blow to the disadvantageous drawback of health with mouth again. On use, basis easy to carry, more Add the scope of application of having widened it, made things convenient for the tourist to use the characteristics such as inflatable mattress.
