ABSTRACT:
An air mattress has a filler check valve connected to an air blower to supply air to the mattress chamber. A holder secured to the air mattress locates the filler check valve in a recessed position relative to an outer wall of the mattress. The filler check valve has a sleeve mounted on the holder and a rod attached to a valve head carrying an annular sealing member. A spring biases the valve head to a closed position wherein annular sealing member engages a beveled face on the inner end of the sleeve. The outer end of the sleeve has a cylindrical collar with internal and external threads. The internal threads of the collar engage external threads of the holder to secure the sleeve on the holder. A cap has an annular flange with internal threads of the collar to close an air passage in the sleeve. Seals located between the collar and sleeve and between the cap and the sleeve inhibit leakage of air from the chamber of the air mattress.
