Title:
BED DEVICE AND DRIVING METHOD OF FLOOR PLATE
Document Type and Number:
Japanese Patent JP2539989
Kind Code:
B2
Abstract:
PURPOSE: To selectively do healthy exercises by use of a bed device by controlling the swing phases of divided parts oscillated by the driving side and driven side respectively.
CONSTITUTION: On putting on an operation switch 37b, a light receiver 35 detects first the light from a projector 34 through a pin hole 32 of a slit plate 33 and the currents to an electromagnetic clutch 31 are cut off to rotate only the driving part 23a. And hence, only divided half 11 of a pair at one side in the width of the bed frame oscillates. When the slit plate 33 is rotated 90 degree in this condition and light beams are received through the next pin hole 32, electric currents are conducted to the electromagnetic clutch 31 and the drive side 23a is connected to the driven side 23b. Thereby, the divided half 11 of the pair at the other side in the width of the bed frame starts to oscillate again in the condition deviated by 90 degree from the divided half 11 of the couple at one side. If putting on again, the slit plate is rotated 180 degree, or the vertical motion of the right and left divided halves 11 can be reversed. Accordingly, users can select the kind and strength of the motion.
