Method of controlling the lifting of bottom sections of lying furniture such as a bed
First Claim
1. 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 separately or simultaneously lifted by lifting mechanisms respectively provided for them, comprising:
- selectively issuing a command from an operating command means to a control means so that respective bottom sections can be operated by the respectively provided lifting mechanisms either respectively independently or in an coordinative manner, detecting the lower limit positions of said respective bottom sections by means of position detecting means, and transmitting to control means the lower limit position of the bottom sections which can be lifted in an coordinative manner.

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.
