Multiple air passages applied to air mattress

Abstract

A multiple air passages applied to air mattress includes a plurality of transverse bladders, in particular, the bladders are longitudinally compressed to define air passages, and cavities are formed between the air passages and some specific bladders for communicating the air passages with an interior of the aforementioned bladders. The air passages of the present invention can apply to an alternating air mattress or to one with multiple zones. By means of the air passages conducive to an air-crossing transmission and a designated distribution, the present invention preferably omits a complex distribution and attains a neat appearance, lower costs, and a mass production.

1 . A multiple air passages applied to air mattress comprising a plurality of transverse bladders; said bladders being divided at intervals by a plurality of score lines; said bladders being longitudinally compressed to define air passages, and cavities being formed between said air passages and some of said specific bladders for communicating said air passages with an interior of said specific bladders. 
     
     
         2 . The multiple air passages applied to air mattress as claimed in  claim 1 , wherein said air mattress includes a first body superimposed on a second body by compressing borders thereof, and said first and second bodies are formed into a plurality of lateral bladders by dividing or supplementing a joint unit. 
     
     
         3 . The multiple air passages applied to air mattress as claimed in  claim 2 , wherein said air passage is defined by longitudinally compressing either said first body or said second body with passage bodies; said concavities are defined on each of said passage bodies. 
     
     
         4 . The multiple air passages applied to air mattress as claimed in  claim 3 , wherein said air passages are formed by disposing a release paper between said bladders and said passage bodies in a processing step; said release paper has a smaller surface area and a narrower width than said passage bodies; a perimeter of said passage bodies is subjected to a squash unlike an interior thereof subjected to a non-squash condition after compressing. 
     
     
         5 . The multiple air passages applied to air mattress as claimed in either  claims 1 , wherein said compression adopts a high-frequency compression welding. 
     
     
         6 . The multiple air passages applied to air mattress as claimed in  claim 1 , wherein a quantity of said air passages of said air mattress is identical to an amount of alternating groups of said bladders. 
     
     
         7 . The multiple air passages applied to air mattress as claimed in  claim 1 , wherein said bladders can be formed into a plurality of action zones, and a quantity of said air passages equals to a quantity of said action zones. 
     
     
         8 . The multiple air passages applied to air mattress as claimed in  claim 1 , wherein either said air passage or any one of said communicated bladders disposes an inlet and an inlet pipe connected thereto; said inlet pipe joints to an air pump. 
     
     
         9 . The multiple air passages applied to air mattress as claimed in  claim 1 , wherein said air mattress further includes a head bladder and a one-way valve disposed at a place where said head bladder meets said bladders within said air passage. 
     
     
         10 . The multiple air passages applied to air mattress as claimed in  claim 1 , wherein said one-way valve includes a supporting portion and a blocking unit; said supporting portion is partially disposed among said air passage; a distal end of said supporting portion does not extend to said concavity of a head bladder; said blocking unit is disposed at an edge of said one-way valve. 
     
     
         11 . The multiple air passages applied to air mattress as claimed in  claim 9 , wherein a CPR deflation valve is disposed at an edge of said head bladder.
