Patent number: 9326904Abstract: An air mattress with an internal pump has a plurality of air cell groups lined up in the lengthwise direction of the air mattress. Each of air cell groups has a plurality of bladder-shaped cells lined up in the lengthwise direction of the air mattress. The air mattress has an air supply/release pump; and an air tube linking the air cell groups and the air supply/release pump in an independent system for each air cell group out of two or more air cell groups. All of the bladder-shaped cells are rod shapes extending in the widthwise direction of the air mattress, and the length of the air cell groups corresponding to the leg area of a reclining person is up to 30% less than that of the other bladder-shaped cells, leaving a space between there and the edge of the air mattress in which the air supply/release pump is disposed.Type: GrantFiled: October 19, 2010Date of Patent: May 3, 2016Assignee: PARAMOUNT BED CO., LTD.Inventors: Katsuyoshi Nomura, Shinji Ueki, Makoto Tanaka, Takayuki Masukawa

Publication number: 20120311790Abstract: Provided is an air mattress with an internal pump wherein an air supply/release pump can be contained within the space occupied by a conventional air mattress. The ease of handling, ease of performing caretaking work, and ease of maintenance of the pump are improved without reducing comfort. The air mattress with an internal pump has a plurality of air cell groups lined up in the lengthwise direction of the air mattress. Each of air cell groups has a plurality of bladder-shaped cells lined up in the lengthwise direction of the air mattress. The air mattress has an air supply/release pump; and an air tube linking the air cell groups and the air supply/release pump in an independent system for each air cell group out of two or more air cell groups.Type: ApplicationFiled: October 19, 2010Publication date: December 13, 2012Inventors: Katsuyoshi Nomura, Shinji Ueki, Makoto Tanaka, Takayuki Masukawa
