Patent number: 10334959Abstract: When, at the initial operation of an air mattress having inflating and deflating functions or at restarting after maintenance, many air cells need to be filled with a large amount of air, the air supply/discharge pump is operated at a driving force (the first power output) close to the maximum driving capacity thereof in order to inflate the air cells as soon as possible. In the normal operation in which the bed user is lying on the bed, when the air supply/discharge pump needs to be driven in order to cause alternate inflation and deflation or in order to prevent the user from touching the bottom, the air supply/discharge pump is driven at a second or third power output lower than the first power output. Thereby, it is possible in the air mattress having inflating and deflating functions to achieve rapid pressure adjustment and alleviate bed user's discomfortable feeling due to the operation noise of the pump upon the pressure adjustment.Type: GrantFiled: August 8, 2018Date of Patent: July 2, 2019Assignee: PARAMOUNT BED CO., LTD.Inventors: Kenta Ohno, Makoto Tanaka, Shinji Ueki

Patent number: 10335335Abstract: For each air cell, air is supplied and discharged through one of three lines independent of one another, every third cell being connected to the common line. The control unit controls inflation and deflation of air cells in turn in such an alternate manner that first the pressure of air in the air cells on the first line is increased and decreased, secondly the pressure of air in the air cells on the second line is increased and decreased, then the pressure of air in the air cells on the third line is increased and decreased. Thereafter, when the back tilt angle of the back bottom has reached a predetermined angle or greater, the control unit increases the pressure of air cells whose pressure is being lowered at that moment so as to produce an inflated mode similar to that of the other air cells. Then, while the back bottom is being raised, the control unit performs an inflation and deflation control of individual lines alternately on a cycle shorter than that in a normal control mode.Type: GrantFiled: June 29, 2015Date of Patent: July 2, 2019Assignee: Paramount Bed Co., Ltd.Inventors: Kenta Ohno, Atsushi Kato, Tomokazu Tachikawa
