ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates generally to toilet seat covering material and, more specifically, to a toilet seat having an integral toilet seat covering material dispenser and disposal device therein. The toilet seat covering material dispenser and disposal apparatus is designed to move a predetermined length of sanitary seat covering material from a dispensing port to a disposal port each time a motor is activated. The toilet seat covering material dispenser and disposal system has a pressure sensor 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 and discarded. A deactivation switch is attached to the seat top to prevent operation when the seat lid is down. This will prevent the covering material from being dispensed while the toilet is being used as a seat.
The covering material is moved by a motor driven belt and pulley system that dispenses the covering material, and a roller-driven disposal system. The covering material is dispensed from a dispensing box of biodegradable disinfectant continuous seat covering material. A battery power source is provided.
The toilet seat has a top portion and a base, which engage each other to form the toilet seat. The toilet seat base has a number of connector posts with holes for connecting with cooperating posts in the top portion of the toilet seat. The toilet seat base also has an aperture for the disposal of used covering material. In addition to the connector posts, the top portion of the toilet seat has two apertures in the top rear portion for dispensing and disposing of the covering material.
2. Description of the Prior Art
There are other paper dispensing devices designed for toilet seats. Typical of these is U.S. Pat. No. 4,926,504 issued to Higuchi et al. on May 22, 1990.
Another patent was issued to Juushi on Mar. 22, 1994 as U.S. Pat. No. 5,295,272. Yet another U.S. Pat. No. 5,561,867 was issued to Roginsky on Oct. 8, 1996 and still yet another was issued on Jun. 22, 1999 to Lorenzi et al. as U.S. Pat. No. 5,913,609.
U.S. Pat. No. 4,926,504
Inventor: Mitsuhiro Higuchi
Issued: May 22, 1990
A toilet seat structure capable of automatically feeding a seat cover paper onto the toilet seat is disclosed. Since the sheet paper feeding mechanism and a paper cutting mechanism operated by an electronic control unit, a specified length of paper appropriate for covering the toilet seat is automatically and accurately fed and positioned on the toilet seat. After use, the seat covering paper can automatically be cut off. For lavatories at public sites in particular, since the user can operate the apparatus to feed the paper from a functional casing to provide a new seat covering paper on the toilet seat for each use, the user can be assured of a clean toilet seat. Also, since the seat covering paper is held immovable on the toilet seat, the use of the paper covered toilet is made easier.
Laid-on paper delivered from a laid-on paper roll and laid on a toilet seat can be easily separated after use, not requiring hands. A toilet is provided with a delivery roller part for clamping the laid-on paper from a laid-on paper roll, the laid on paper having perforated lines to cut off the laid-on paper for each amount of use, and the delivery roller part pulling out the laid-on paper by the rotation thereof and delivering the laid-on paper onto the toilet seat. A rear portion of the toilet seat is vertically movably provides an upwardly urgingly supported by springs in a rear part of the toilet. A brake mechanism for stopping the rotation of the delivery roller part due to the lowering motion of the toilet seat is also provided.
An apparatus for providing a protective sheet or substrate on the upper surface of a toilet seat includes a supply storage container disposed at a first end of the toilet seat to store a supply of individual protective sheets, each having an opening, and connected in a continuous fashion. The protective sheet extends across the top of the toilet seat and a take-up container disposed at a second end of the toilet seat opposite to the first end is for taking up the sheet after use. A mechanism is provided for advancing the sheet and winding it on a shaft.
Apparatus for conveying a protective covering along a toilet seat is provided. The apparatus includes a housing containing a support structure for the toilet seat, a feeder spool from which a roll of unused protective covering material is fed, a take-up spool for used protective covering and a drive mechanism operated by a water supply system to advance a pre-determined length of the protective covering along the toilet seat, which length generally corresponds to the perimeter of the toilet seat.
While these toilet seat paper dispensing devices may be suitable for the purposes for which they were designed, they would not be as suitable for the purposes of the present invention, as hereinafter described.
SUMMARY OF THE PRESENT INVENTION
A primary object of the present invention is to overcome the shortcomings of the prior art.
Another object of the present invention is to provide a sanitary toilet system.
Another object of the present invention is to provide a sanitary toilet seat having a reservoir of disposable toilet seat covering material.
Yet another object of the present invention is to provide a sanitary toilet seat having means for dispensing the toilet seat covering material.
Still yet another object of the present invention is to provide a sanitary toilet seat having means for positioning a sanitary toilet seat covering material over the toilet seat.
Another object of the present invention is to provide a sanitary toilet seat having means for disposing of used toilet seat covering material as new covering material is being dispensed.
Yet another object of the present invention is to provide a sanitary toilet seat having means for preventing the dispensing or disposal of toilet seat covering material while the toilet seat lid is in the down position.
Still yet another object of the present invention is to provide a user selectable time delay switch for selectively varying the initiation of the dispensing/disposal cycle.
Another object of the present invention is to provide means for selectively replacing the sanitary covering material reservoir.
Additional objects of the present invention will appear as the description proceeds.
The present invention overcomes the shortcomings of the prior art by providing having an integral toilet seat covering material dispenser and disposal device therein. The toilet seat covering material dispenser and disposal apparatus is designed to move a predetermined length of sanitary seat covering material from a dispensing port to a disposal port each time a motor is activated.
The toilet seat covering material dispenser and disposal system has a pressure sensor 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 and discarded. A deactivation switch is attached to the seat top to prevent operation when the seat lid is down. This will prevent the covering material from being dispensed while the toilet is being used as a seat.
The covering material is moved by a motor driven belt and pulley system that dispenses the covering material, and by a roller-driven disposal system. The covering material is dispensed from a dis
