ABSTRACT:
This invention relates to an inflatable article such as an air bed or the like and includes a deformable bag 12 which is coupled to the air bed 10 via a stem 18. The deformable bag is opened to allow air to enter the bag and is then deformed to force air from the bag 12 into the article 10 to inflate the article. The bag in the deformed condition forms a valve for preventing excape of air from the bed 10 and may be inserted into a pouch 20 provided on the bed 10. The invention may also include a chamber 60 disposed between the bag 12 and the air bed 10 for enabling the bed 10 to be inflated to a relatively high pressure. A first valve 64 is provided between the chamber and the bag 12 and the open condition allows air to pass from the bag 12 into the chamber 60. A second valve 62 is provided which opens upon deformation of the chamber 60 to allow air to pass from the chamber 60 into the air bed 10.
