Patent number: 6568011Abstract: An inflatable mattress comprises a flexible bottom layer, a top layer sealed to the bottom layer through a wall, wherein the bottom and top layers and the wall define an outer frame of the inflatable mattress, and a middle layer disposed between the top and bottom layers. The bottom surface of the middle layer is sealed to the bottom layer through a plurality of laterally disposed I-beam structures to form a lower chamber. The top surface is attached to the top layer through a plurality of X-beam structures to form an upper chamber. A peripheral edge of the middle layer may be sealed with the wall to prevent the upper and lower chambers from being in fluid communication with each other.

Patent number: 6299420Abstract: An air pump is a dual action manually driven with a piston and two intake and two exhaust check values that respectively operate with one intake port and one exhaust port. These check valves operate in tandem with each other during each pumping stroke, either up or down. During each pumping stroke, one intake check valve and one exhaust check valve are open with their counterparts closed, to provide continuous discharge of compressed air through the exhaust port and also to provide continuous intake of air through the intake port. The air pump includes a cylindrically shaped hollow reservoir housing, a base connected to one end of the housing, an intake port and an exhaust or inflate port which are mounted on the base, an elongated piston shaft extending along the longitudinal axis of the housing, and a handle perpendicularly disposed with respect to the piston shaft to assist pumping of the piston shaft.Type: GrantFiled: April 6, 2000Date of Patent: October 9, 2001Assignee: Intex Recreation Corp.Inventors: Richard A.

Patent number: 6257550Abstract: A drain valve adapter is for use with a hose and a drain valve mounted to a container, wherein the drain valve of the container defines a passageway for aqueous solution. The drain valve adapter comprises a tubular body having a mating member and a plunger member which are in fluid communication with each other, the plunger member being configured to be disposed inside the drain valve along the passageway. The drain valve further comprises a ring cap defining a through hole and being disposed in surrounding relation to the tubular body for releasably engaging the drain valve. The plunger member has at least one prong extending therefrom to force open a drain plug blocking the passageway of the drain valve. Preferably, the plunger member has a plurality of prongs extending therefrom. The plurality of prongs define spaces therebetween to allow free flow of the aqueous solution in the container. The mating member has a threaded outer surface for engaging with a female coupler of a standard garden hose.Type: GrantFiled: April 6, 2000Date of Patent: July 10, 2001Assignee: Intex Recreation Corp.Inventors: Richard A. Saputo, Hua Hsiang Lin, Yaw-Yuan Hsu
