Abstract: An electric opening and closing device that opens and closes a toilet seat or lid by a torque output to an output member includes: a motor; a reduction gear mechanism having gear members including a gear member of a spur tooth and transmitting the torque of the motor to the output member; and a torque limiter that includes a first rotating member rotating integrally with a first gear member rotating by the torque among the gear members, a second rotating member rotating integrally with a second gear member connected to the output member via the gear member of the spur tooth or the output member, and a friction member engaged with one of the first and second rotating members, and that generates a slip between the friction and other rotating members to interrupt the transmission of the torque when a torque exceeding a value acts on the output member.

Abstract: A toilet seat assembly comprising a seat (2) and hinge means (5) for hingedly attaching the seat (2) to a toilet. The hinge means (5) comprises a mounting block (50) having an arcuate slot (17), and an arcuate seat tang (20) extends rearwardly of the seat which is slidable in the arcuate slot of the mounting block. The assembly may also comprise a lid (3); and hinge means for hingedly attaching the lid (3) to a toilet; and an arcuate lid tang (23) extending rearwardly of the lid which is also slidable in the arcuate slot (17) of the mounting block (50).

Abstract: A bobbin assembly is provided that is suitable for dispensing webbed material using a power driven coupling in a toilet seat assembly having a housing with wall portions. The bobbin assembly comprises an extruded thermoplastic hollow tube having a plurality of splines disposed longitudinally therein and an end cap assembly adapted for connection to the wall portion. The splines are constructed and arranged in mating inter-engagement with the power driven coupling. The end coupling is spring biased toward the hollow tube to mate with the hollow tube. The bobbin assembly allows for identical supply and take-up bobbins.

Abstract: A mechanism for raising and lowering a toilet seat in response to actuation of foot pedals. An actuation cylinder with a contained piston is connected between the toilet bowl and the toilet seat. Water from the supply line for the toilet is routed to the actuator cylinder when a seat up pedal is depressed and causes the piston to extend out of the actuation cylinder and raise the seat. Operation of a flush pedal causes the water within the actuation cylinder to drain so that the toilet seat lowers. A mechanical linkage from the flush pedal to the flush mechanism of the toilet links toilet flushing to the seat lowering action, ensuring that the seat is lowered after each flush.

Abstract: In an inside of a cassette 11 which is stored integrally with a toilet seat lid 1, a plurality of toilet seat covers 12 are stored, and by opening and closing of the toilet seat lid 1 which stores the cassette 11, a part of the toilet seat cover 12 which is exposed from a lower lid 7 of the cassette 11 contacts an adhesive button 3 which is disposed on a toilet set 14 or a seat 2 of the toilet seat and adheres to this, and thereby, the toilet seat cover 12 is set on the toilet seat 14 or the seat 2 of the toilet seat. Also, in order to facilitate refilling of the toilet seat covers 12 into the inside of the cassette 11, disposed are fixing means and opening and closing means by which the toilet seat lid 1 and the cassette 11, and an upper lid 5 and the lower lid 7 of the cassette 11 can be easily detached and attached, or opened and closed.

Abstract: The present invention provides a toilet seat assembly that can be assembled and disassembled without the use of tools by aligning various components of the assembly at a predetermined angle with respect to one another. Another aspect of the invention includes a system composed of a plurality of toilet seat assemblies that communicate information onto and receive information from a computer network that can include the Internet in one embodiment. Another aspect of the invention includes a kit for serviceing the assembly of the invention that includes a plurality of rolls of plastic sleeves.

Abstract: An improved electromechanical assembly advances a tubular protective covering around a toilet seat. The covering is stored on a reel, and pulled off from the reel as it is replaced, and the used covering is taken up on a second reel. An activation button exposed through the top of the assembly is depressed to actuate a switch assembly which, in turn, actuates a drive mechanism. By actuating the drive mechanism, the cover is moved through a predetermined distance in such a manner that when it is in the mounted position, the toilet seat body is completely surrounded by the tubular cover. An upper housing portion has an integral pressure blade for exerting a constant downward force on the advancing protective covering. The pressure ensures adequate contact between the covering and a counter shaft assembly which communicates magnetically with internal electronic circuitry.

Abstract: A sanitary toilet seat is provided which has an integral toilet seat covering material dispenser and disposal device. The device moves a predetermined length of sanitary seat covering material from a dispensing port to a disposal port each time a motor is activated. A pressure sensor is provided for resetting the delay timer in response to high pressure and starting the delay timer in response to low pressure. Once the manually adjustable period of delay has expired, a relay activates a motor, which starts the motion of the covering material about the toilet seat. The motor continues until it is deactivated by a micro switch after one full cycle of operation in which a predetermined length of covering material has been dispensed. A deactivation switch is provided to prevent operation when the seat lid is down, preventing the covering material from being dispensed while the toilet is being used as a seat.
