Abstract: A control unit controls a drive unit so that a back angle ?, which is an elevation angle of a back bottom, and a knee angle ?, which is an elevation angle of a knee bottom, change according to a pre-set pattern. The control unit comprises a memory unit for storing a plurality of patterns of linking a coordinate point (0,0) in a (?,?) coordinate, in which each of the bottoms is in a horizontal state, and a coordinate point (?0, ?0), in which the back bottom is raised, with a plurality of points; a selection unit for selecting one pattern from the plurality of patterns stored in the memory unit; and a computation unit for controlling the drive unit so that the back angle ? and the knee angle ? change according to the pattern selected by the selection unit. Therefore, the patient can be prevented from being displaced on the bed and from being subjected to a sense of pressure on their stomach or chest.

Abstract: A coordinative control method for adjusting the back and knee bottom sections of an adjustable bed or the like, and a computer program for implementing the method, are provided. Specifically, a method for adjusting the back and knee bottom section is provided, in which the angular positions thereof are adjusted according to a preset action pattern. The initial starting positions of the adjustable sections are taken into account, and adjusted to a position corresponding to the closest point on a curve representing angular movement of the sections during the adjustment process. Then, the sections are adjusted in a manner that prevents exertion of uncomfortable pressure upon the torso of a user, and prevents sliding of a user relative to the foot of the bed.

Abstract: A bottom adjusting action control system for an adjustable bed is provided that facilitates adjustment of the adjustable bottom sections of the bed via a predetermined path of angular adjustment in reaching final set positions for the back and knee bottom sections. In particular, the control system of the present invention provides a means of adjusting the angular positions of adjustable bottom sections of the bed to predetermined final positions via preset bottom coordinative action patterns carried out by a controller means. The preset bottom coordinative action patterns raise and lower adjustable back and knee bottom sections of the bed in a coordinated manner, so as to adjust the bottom sections of the bed to the chosen angular positions without causing the user to slide relative to the bed, and without exerting uncomfortable abdominal pressure on the user.

Abstract: This invention relates to a method of controlling the lifting of bottom sections of lying furniture such as a bed that has a back bottom section for lifting the back portion of a lying person and a knee bottom section for lifting his/her knee portion, in which the respective bottom sections can be lifted by the lifting mechanisms respectively provided for them, characterized in that the respective bottom sections are so constituted that they can be operated by the respectively provided lifting mechanisms either respectively independently or in an coordinative manner under a command selectively issued from an operation command means to a control means, and that position detecting means for detecting the lower limit positions of said respective bottom sections are installed at adequate places, wherein the control means lifts the respective bottoms sections in an coordinative manner subject to the condition that the position detecting means of the respective bottom sections detect the lower limit positions.

Abstract: In (?, ?) coordinates defined by a back angle ? and a knee angle ?, a pattern that connects between a coordinate point (0, 0) at which each of a back bottom and a knee bottom is horizontal and a coordinate point (?0, ?0) which is a final reaching point for a back lift-up operation and at which the back bottom is lifted up by a plurality of points is set, an optimal pattern which provides less slipperiness and less oppressive feeling is acquired beforehand, and a control section moves the back bottom and the knee bottom along the optimal pattern. This reliably prevents a carereceiver from slipping, regardless of subjective judgment by an operator or a carer, at the time of performing a back lift-up operation and back lift-down operation of an electric bed. It is therefore possible to prevent pressure from being applied onto the abdominal region and chest region of the carereceiver, thus relieving the carereceiver and carer of the burden.
