PURPOSE: To adapt the bed to the sick or wounded state of a user by adjusting the rising angle of a floor part. CONSTITUTION: In the bed, a controller 7 in a control box provided to a frame under the floor part receives a key input signal Sb regarding an operation command of the floor part and detects a rotational quantity corresponding to the rising angle in the middle of the rising of the floor part 2 up to a set rising angle by a rotational quantity detecting means provided to a driving motor 8. Then the signal St regarding the rotational quantity is compared with a signal regarding the rotational quantity corresponding to the set angle of the driving motor 8 found from a rising angle setting signal Sa and the driving motor 8 is controlled to start and stop operating. Here, the setting can not be done unless an operation switch for floor part rising angle setting is pressed for a certain time, and then angle setting by a demented person is not accepted. Consequently, every demented user can have pleasant bed life. |
