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.

The body is hollow and has a top surface and a bottom surface. The first and second chambers are defined in the body from the top surface to the bottom surface and are separated hermetically from each other by an internal barrier attached vertically to the top surface and the bottom surface. Although the vertically internal barrier divides air in the body into two parts restrictedly flowing respectively in the chambers, the vertically internal barrier is unable to limit the air inside each chamber in an upper area adjacent to the top surface to further reduce the deformation of each chamber as persons lying on the inflatable mattress.
  • To overcome the shortcomings, the present invention provides an inflatable mattress to mitigate or obviate the aforementioned problems.
  • SUMMARY OF THE INVENTION
  • The main objective of the invention is to provide an inflatable mattress that uniformly supports persons lying on the inflatable mattress and keep each person's movement without interfering with others.

The upper chamber (11) has an inner top surface and an inner bottom surface. The lower chamber (12) is located under the upper chamber (11) and has an inner top surface and an inner bottom surface. The partitioning member (111) has a top surface, a bottom surface and multiple through holes (112) defined through the partitioning member (111) and communicating with the upper and lower chambers (11, 12).
  • The pad (15) is annular, is attached to the bottom of the body (10) and has an internal chamber (13) defined in the pad (15).
  • The upper holding straps (7) are mounted between the top of the body (10) and the top surface of the partitioning member (111), are located between the inner top and bottom surfaces of the upper chamber (11) and hold the upper chamber (11) in a predetermined shape such as a rectangular shape so that the upper chamber (11) would not deform to be ball-like.
  • The lower holding straps (3) are mounted between the bottom surface of the partitioning member (111) and the bottom of the body (10), are located between the inner top and bottom surfaces of the lower chamber (12) and hold the lower chamber (12) in a predetermined shape such as a rectangular shape so that the lower chamber (12) would not deform to be ball-like. The partitioning member (111), upper holding straps (7) and lower holding straps (3) cooperate to keep the body (10) in a predetermined shape such as a rectangular shape from deforming to be ball-like.
  • The chamber walls (20) are made of resilient materials are arranged in a row, are mounted in the primary chamber (1) adjacent to the top of the body (10), are mounted between the top of the body (10) and the top surface of the partitioning member (111) and may be located between the inner top and bottom surfaces of the upper chamber (11). Adjacent chamber walls (20) separate hermetically from each other at an interval. Each chamber wall (20) has an inner top surface, an inner bottom surface and a sub chamber (2). The inner top surface of the chamber wall (20) is a part of the top of the body (10). The inner bottom surface of the chamber wall (20) is a part of the partitioning member (111). The sub chamber (2) is defined in the chamber wall (20).
  • The air pump assembly is mounted on the body (10) and has an air pump (4), a primary inlet-and-outlet pipe (41) and multiple auxiliary inlet-and-outlet pipes (42, 43).
  • The air pump (4) is mounted through the annular sidewall of the body (10) and selectively inflates or deflates at least one of the primary chamber (1) in the body (10) and the sub chambers (2) in the chamber walls (20).
  • The primary inlet-and-outlet pipe (41) is mounted on the air pump (4), connects to the primary chamber (1), may extend in the primary chamber (1), may extend in the upper chamber (11) and allows the air pump to inflate or deflate the primary chamber (1) through the primary inlet-and-outlet pipe (41).
