Title:
ELECTRIC BED, CONTROL METHOD THEREFOR, AND CONTROLLER
Document Type and Number:
Japanese Patent JP3707555
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To relieve burden on a cared person and a caring person by reliably preventing the cared person from being shifted from an original position on an electric bed without the subjectivity of the caring person being an operator when the bed is inclined upward or downward, and preventing a pressure sensation from being given to the belly and breast of the cared person.
SOLUTION: A back angle is defined as α, and a knee angle is as β in (α, β) coordinates. In the coordinates, a pattern is set, which is obtained when a coordinate point (0, 0) where each bottom is in a horizontal state is connected by a plurality of points to a coordinate point (α0, β0) where a back bottom is erected, which is the final arrival point of an upward inclining operation. Then, an optimum pattern with little shifting and pressure sensation is previously obtained, so that a control part moves the back bottom and the knee bottom along the optimum pattern.
