Inflatable mattress

Abstract

An inflatable mattress has a body and multiple chamber walls. The body has a top, a bottom, an annular sidewall, a primary chamber defined in the body and a partitioning member mounted in the primary chamber between the top and bottom surfaces. The chamber walls are arranged in a row, are mounted in the primary chamber adjacent to the top of the body above the partitioning member. Adjacent bags separate from each other at an interval. Each chamber wall has a sub chamber. The separate chamber walls individually and respectively support persons lying on the inflatable mattress so that each person's movement only deforms a corresponding chamber wall instead of deforming other chamber walls on which other persons lie. Therefore, the persons on the inflatable mattress would not interfere with each other.

1 . An inflatable mattress comprising:
 a body having a top, a bottom, an annular sidewall and further having   a primary chamber defined in the body; and   a partitioning member mounted in the primary chamber, mounted on the annular sidewall between the top and the bottom of the body, holding the annular sidewall, dividing the primary chamber into an upper chamber and a lower chamber and having a top surface and a bottom surface; and   multiple chamber walls arranged in a row, being separated, mounted in the primary chamber adjacent to the top of the body and mounted between the top of the body and the top surface of the partitioning member, and each chamber wall having a sub chamber.   
   
   
       2 . The inflatable mattress as claimed in  claim 1  further comprising an air pump assembly mounted on the body and having
 an air pump mounted through the sidewall of the body and selectively inflating or deflating at least one of the primary chamber and the sub chambers;   a primary inlet-and-outlet pipe mounted on the air pump and connecting to the primary chamber; and   multiple auxiliary inlet-and-outlet pipes mounted on the air pump and connecting respectively to the sub chambers.   
   
   
       3 . The inflatable mattress as claimed in  claim 2 , wherein:
 the upper chamber has an inner top surface and an inner bottom surface;   the lower chamber has an inner top surface and an inner bottom surface; and   the body further has multiple upper holding straps mounted between the top of the body and the top surface of the partitioning member, located between the inner top and bottom surfaces of the upper chamber and holding the upper chamber.   
   
   
       4 . The inflatable mattress as claimed in  claim 3 , wherein the body further has multiple lower holding straps mounted between the bottom surface of the partitioning member and the bottom of the body, located between the inner top and bottom surfaces of the lower chamber and holding the lower chamber. 
   
   
       5 . The inflatable mattress as claimed in  claim 4 , wherein each chamber wall has
 an inner top surface being a part of the top of the body; and   an inner bottom surface being a part of the partitioning member.   
   
   
       6 . The inflatable mattress as claimed in  claim 5 , wherein the body further has a pad being annular, attached to the bottom of the body and having an internal chamber defined in the pad. 
   
   
       8 . The inflatable mattress as claimed in  claim 6 , wherein the partitioning member is hollow and has an interior chamber being flat and defined in the partitioning member. 
   
   
       9 . The inflatable mattress as claimed in  claim 2 , wherein:
 the primary inlet-and-outlet pipe extends in the primary chamber   the auxiliary inlet-and-outlet pipes extend respectively in the sub chambers.   
   
   
       10 . An inflatable mattress comprising:
 a body having a top, a bottom, an annular sidewall and further having   a primary chamber defined in the body; and   a partitioning member mounted in the primary chamber, mounted on the annular sidewall between the top and the bottom of the body, holding the annular sidewall, dividing the primary chamber into an upper chamber and a lower chamber and having a top surface and a bottom surface; and   multiple chamber walls arranged in a row, mounted in the primary chamber adjacent to the top of the body and mounted between the top of the body and the top surface of the partitioning member, adjacent chamber walls separating from each other at an interval, and each chamber wall having a sub chamber.
