Abstract

The utility model relates to a portable inflation pillow, which is hot-pressed into an air chamber structure which can be closed, and the utility model is made of skim coating plus material. The utility model is characterized in that a plurality of dispersed parallel strip tube-shaped air chamber structures are adopted to replace the pocket type air chamber structure, so that the pillow is formed into a flat shape. The utility model overcomes the discomfortable phenomenon that the head of a person is easy to slide, because the middle of the pocket type is high and the periphery of the pocket type pillow is low. The inflation program of the utility model can not influence the softness of the pillow, so the utility model can really reach the effect of a foam pillow.

Description

Portable pneumatic die cushion

The utility model belongs to a kind of daily living article, particularly is applicable to field work, often changes the habitat or does the situation of short-term tourism.

Frequent conversion habitat makes that to carry those volumes big and be worth not highly, but in demand again necessity for life becomes the very thing of trouble in the daily life.Pillow is exactly a kind of of these class article.Every new place how to make the pillow softness, comfortable all be make the people feel the difficulty thing.The clothing of carrying have to be filled in pillowcase when people are helpless and make an interim pillow, the effect that not only has random adjustment form firmly but also not makes people lose comfort in bed, has influence on the tired efficient recovery that has.People have invented the gasbag-type pillow at present, become a balloon-like by the fabric thermoplastic of having hung rubber or plastic cover, and air bag communicates with a charging connector, and it is very little to have put the gas volume, is easy to carry about with one.During use, in air bag, charge into gas, just become a pillow that softness is comfortable by valve.Use much more comfortable than the pillow of normal laundry filling certainly.But air bag often is difficult for grasping inflation procedure.Inflation is few, does not have due effect, and the inflation too foot pillow head that gets on is easily rolled on air bag, and softness is had a surplus and the comfort level deficiency, and one that becomes present pneumatic die cushion significantly lacks limit.

The purpose of this utility model promptly provides the structural design of a new inflatable pillow, make it can not form single ball face shape, and form the equally approximate elastic linear shape of similar common pillow, thereby can not produce head bias when pneumatic die cushion is used slides, and increases comfort.

Basic design of the present utility model promptly is that the single air sac type structure of tradition is transformed into the air chamber structure that independently is shaped by several, so just can prevent fundamentally that pneumatic die cushion inflation back from forming the outstanding steamed bun shape appearance in a centre.Concrete method is spaced heat in the two-layer lining up and down of composition air bag to be extruded many ribs come, thereby whole air bag space is evenly divided into the bar tubulose air chamber that is parallel to each other, so, though the circular-arc feature that the outside geometric properties of each bar tubulose air chamber exceeds in the middle of still presenting behind sufficient certain gas, make the gabarit shape of whole pillow become an almost plane, application was close with the Foam pillow of higher gears with regard to obviously being better than existing pneumatic die cushion after the pneumatic die cushion that has certain thickness and elastic-restoring force again, such pneumatic die cushion head added pillowcase, pillow cover.

How further specify goal of the invention of the present utility model below in conjunction with accompanying drawing realizes.

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

Fig. 2 is the A-A cutaway view of Fig. 1.

Fig. 3 is the logical schematic diagram of series connection between the independent air chamber.

Wherein 1 is upper fabric, and 2 is lower fabric, and 3 is bar tubulose air chamber, and 4 is valve, and 4A is the air chamber valve, and 5 is connectivity trachea, and 5A is that tracheae is connected plug-in unit with valve 4A, and 6 are the muscle of cutting apart between the air chamber, and 6A is located at the ventilation trunnion of cutting apart on the muscle.

Design upper and lower kiss-coating lining 1,2 according to the designed good form of Fig. 1, and compression moulding in advance, then up and down sheet put the high frequency press and be provided with under the template of parallel projection hot-forming, and on air chamber, set valve 4 in advance just can be with thermal synthesis finished product of pneumatic die cushion.Charging into gas from valve 4 during use makes each air chamber rising just can form a substantially flat and the moderate pillow of elasticity.In order to guarantee to communicate between each air chamber 3, when hot-forming, can in cutting apart rib 6, set in advance ventilation trunnion 6A, can be by trunnion 6A with each air chamber inflation from a valve.Such structure is comparatively convenient convenient.Can certainly on mould, do certain PROCESS FOR TREATMENT, make and cut apart rib and each air chamber is not separated fully.

Fig. 3 provides the air chamber structure design that another kind is mutually independent.Each air chamber is independent design valve 4A all, can design every elasticity and soft Cheng Du that air chamber is different like this, makes whole pillow can produce more comfortable sensation according to user's custom.Can certainly get up to form an integral body being communicated with between each air chamber by valve connector 5A and connectivity trachea (5), use also very simple and easy, convenient.

According to experiment, below the long 60cm of common single pillow, below the wide 35cm, 4-8 bar air chamber can be set, its effect is just quite desirable.

By the pneumatic die cushion that above structure is made, dispose suitable pillowcase, pillow cover and use with daily foam pillow and there is no difference, quite comfortable, a depthkeeping is subjected to field worker, traveller, the employee's that moves about welcome energetically.

Claims
