Title: Motor-driven open/close device for toilet bowl seat and seat cover
Inventor: ITO NOBORU
IPC: A47K13/10
Filed: 1996-08-21
Abstract: PROBLEM TO BE SOLVED: To properly stop the motion of a seat and a seat cover at a totally closed position, regardless of a difference in the size or shape of a toilet, by providing a driven means for opening and closing the toilet bowl seat and the seat cover, and causing the drive means to stop an open/close operation, upon the detection of the status that both of the seat and the seat cover are closed and in contact with a toilet bowl. SOLUTION: When a seat switch 31 and a seat cover switch 35 are operated in the condition E where a seat cover 33 and a seat 29 are in a totally open state, a controller 25 controls two-phase stepping motors 15 and 27, thereby closing both of the seat 29 and the seat cover 33. When only the seat switch 31 is operated, the controller 25 controls only the two-phase stepping motor 15, and the seat 29 is thereby closed. At the time of close driving the seat 29 and/or the seat cover 33, the controller 25 reads an output signal from an encoder 26 and stops the operation of the two-phase stepping motors 15 and/or 27, according to a fluctuating signal, upon the collision of the seat 29 and/or the seat cover 33 with a toilet bowl, thereby stopping the seat 29 and/or the seat cover 33 at a totally close position properly.
