Patent number: 8683632Abstract: An internal valve (10, 10? or 10?) and its methods of use for stabilizing and reinforcing inflatable objects are disclosed. The internal valve is a novel, simple modification to conventional check valves with the addition of a discharging means (14, 22 or 28)for external control. An internal supplemental chamber comprises one or more partitions that are secured, directly or by I-beams (40?), to main chamber's walls (40) of an inflatable object and stretched when the main chamber is inflated. With the internal valve as the passage to and from the main chamber, the enclosed or isolated supplemental chamber (30, 30?, 32, 34, 36 or 38) functions as a stabilizing or reinforcing component. A plurality of chambers 36 can form cylinder beams for an inflatable mattress.Type: GrantFiled: July 13, 2007Date of Patent: April 1, 2014Inventor: Zhengping Zhang

Publication number: 20140013514Abstract: A mattress including a plurality of cells aligned and disposed on a body pressure working surface of a substrate that supports a human body; and a pressure control member that changes a height of each cell by adjusting a pressure in a fluid chamber formed within the cell. The cells are configured such that as the each cell is inflated by fluid supplied to the fluid chamber within the cell, the height of the each cell increases and a width dimension of the each cell in a direction of alignment decreases, and that peripheral portions of adjacent cells in the direction of alignment are overlapped with each other prior to cell inflation.Type: ApplicationFiled: September 18, 2013Publication date: January 16, 2014Applicant: TOKAI RUBBER INDUSTRIES, LTD.Inventor: Akitsugu MISAKI
