Abstract

An inflatable bed unit includes an inflatable primary bed that has a main part, a head part connected to and in fluid communication with the main part and pivotable relative to the main part, a pillow part connected to the head part such that the head part is raised by the pillow part and is pivoted relative to the main part when the pillow part expands upon injection of air therein, and a check valve interconnecting the pillow part and the head part and defining a valve opening that is opened to permit air flow from the pillow part to the head part when the pressure in the pillow part is greater than that in the head part, and that is closed to prevent air flow from the head part to the pillow part when the pressure in the head part is greater than that in the pillow part.

Description

    BACKGROUND OF THE INVENTION
  • 1. Field of the Invention
  • This invention relates to an inflatable bed unit, more particularly to an inflatable bed unit with an inflatable primary bed that includes an inflatable main part, an inflatable head part, and an inflatable pillow part with a check valve that permits air flow from the pillow part to the main part when the pressure in the pillow part is greater than that in the head part.
  • 2. Description of the Related Art
  • FIG. 1 illustrates a conventional inflatable bed that includes a main part 21, a head part 22 pivoted to and in fluid communication with the main part 21, and a pillow part 20 that is disposed below and connected to the head part 22, and that is in fluid communication with the head part 22. The main part 21 is provided with an injection valve 23 for injecting air into the inflatable bed. The head part 22 is provided with a reliefe valve 24 for relieving the pressure in the inflatable bed. The head part 22 is raised and is pivoted relative to the main part 21 to an inclined angle relative to the main part 21 when the pillow part 20 expands upon injection of air into the inflatable bed. However, since the pillow part 20 is in fluid communication with the main part 21 and the head part 22, adjustment of the angle of the head part 22 relative to the main part 21 by relieving the pressure in the pillow part 20 would reduce the pressure in the main part 21 and the head part 22, which, in turn, results in a decrease in the comfort that the inflatable bed can provide.
    • SUMMARY OF THE INVENTION

    • DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
  • FIGS. 2 to 4 illustrate the first preferred embodiment of an inflatable bed unit with an inflatable primary bed 3 according to this invention.
  • The inflatable primary bed 3 includes: an inflatable main part 31; an inflatable head part 30 connected to and in fluid communication with the main part 31, the head part 30 having a bottom end 300 and being pivotable relative to the main part 31; an inflatable pillow part 4 connected to the bottom end 300 of the head part 30 such that the head part 30 is raised by the pillow part 4 and is pivoted relative to the main part 31 from a horizontal level (see FIG. 2) to an inclined angle relative to the main part 31 (see FIG. 3) when the pillow part 4 expands upon injection of air therein; and a check valve 5 interconnecting the pillow part 4 and the head part 30 and defining a valve opening 50 that is opened to permit air flow from the pillow part 4 to the head part 30 when the pressure in the pillow part 4 is greater than that in the head part 30, and that is closed to prevent air flow from the head part 30 to the pillow part 4 when the pressure in the head part 30 is greater than that in the pillow part 4.
  • In this embodiment, the check valve 5 includes a valve housing 52 that extends into the pillow part 4 and the head part 30 and that is formed with an outlet 53 in fluid communication with the head part 30, and a flexible membrane 51 that serves as a valve piece of the check valve 5, that is flexed away from the valve opening 50 when the pressure in the pillow part 4 is greater than that in the head part 30, thereby opening the valve opening 50, and that is flexed toward the valve opening 50 and that abuts against a periphery of the valve opening 50 when the pressure in the head part 30 is greater than that in the pillow part 4, thereby closing the valve opening 50.
  • The pillow part 4 includes an injection valve 42 for injecting air into the pillow part 4, and a reliefe valve 43 for relieving the pressure in the pillow part 4 so that, by virtue of the check valve 5, the inclined angle of the head part 30 relative to the main part 31 can be adjusted independently of the pressure in the head part 30 and the main part 31 through adjustment of the pressure in the pillow part 4, and that the head part 30 can be restored from the inclined angle to the horizontal level relative to the main part 31 when the pressure in the pillow part 4 is completely relieved.
