Description
- (1) Technical Field
- The present invention relates to an automatic toilet device. More particularly, this invention relates to a foot operated device for raising and lowering the toilet seat and flushing the toilet during the toilet seat lowering cycle.
- (2) Background
- It is generally understood that in at least one respect, whether a person is male or female usually determines in what position, either up or down, that person would prefer a toilet seat to be in for use of the toilet. Generally, a male prefers the toilet seat to be in a raised position, while the female prefers the toilet seat to be in a lowered position for conformity with their respective anatomies. Typically, due to a male's behavioral patterns, however, it is widely accepted that in at least a substantial number of cases the male will not return the toilet seat to its lowered position after his use, thus rendering the toilet unsuitable for use by a subsequent female user.
- A toilet seat remaining in an upright position could lead to a number of problems. On many occasions a certain amount of animosity between the females and males in a dual gender household may arise if the females have to continually return the toilet seat to its lowered position for their use. Further complications could arise if a female, in a partially somnolent state, attempted to use the toilet in the dark when the seat was in a raised position. Moreover, a raised toilet seat leads to a certain level of unsightliness, thus, possibly causing further tension if certain members of the household attempt to maintain the bathroom area in an orderly manner. Other problems could arise for a toilet user if the toilet seat was not in the most desirable configuration for a specific user. Some of these problems include difficulty in the manual operation of lowering or raising the toilet seat by persons suffering a variety of illnesses or handicaps, or by small children.
- In addition to a toilet seat remaining in a prolonged raised position, there is also a certain loss of hygiene which occurs when a user is required to physically make contact with the toilet seat to either raise or lower the seat. As is well understood, the toilet seat and toilet seat area require a high level of disinfecting maintenance in order to provide a relatively free area from bacteria and germs. Since continued disinfection of this area is generally not feasible, a toilet seat will typically not be maintained in its most sanitary condition. Consequently, any user who must physically contact the toilet seat to either raise or lower it will be subject to these germs, and thus, may put his or her health at differing levels of unnecessary risk.
- Another concern is that the content of the toilet bowl may give off bad odor. After using the toilet, the male user normally has to close the toilet seat by hand, manually reach for the flush handle, and move the flush handle to flush the toilet. Some users may forget to do this. Other users may not want to touch the flush handle due to hygiene concerns.
- In the past toilet seat lifting and lowering has been attempted in numerous ways. Even today many people lift the toilet seat and toilet lid by hand. However, as discussed previously there are problems associated with hand lifting and lowering of the toilet seat. Mechanical means of lifting and lowering the toilet seat were attempted in U.S. Pat. No. 5,829,067 titled Toilet Seat Lift Assembly that is a hand-activated device; U.S. Pat. No. 6,158,059 titled Foot Actuated Toilet Seat where a leaf spring aids in the operation; U.S. Pat. No. 6,233,751 titled Toilet Flushing and Seat Lifting System; U.S. Pat. No. 6,539,557 titled Toilet Seat Positioning Assembly; and U.S. Pat. No. 6,651,262 titled Foot Operated Commode System. Yet these attempts all still require a user to remember to activate the system to lower the toilet seat. Other means for automatic lowering of the toilet seat are activated based on time or a timer system as shown in U.S. Pat. No. 4,995,120 titled Toilet Seat Closing Device; U.S. Pat. No. 5,279,000 titled Automatic Toilet Seat Lowering Hinge Assembly; and U.S. Pat. No. 5,794,277 titled Automatic Toilet Seat Closing Device where the hinge assembly between the toilet seat and the toilet drive operate the lowering of the toilet seat. These attempts normally require a new toilet seat and extensive hardware for the hinge assembly. A combination of U.S. Pat. No. 5,307,524 titled Automatic Toilet Seat Device and U.S. Pat. No. 5,603,127 titled Auto Flush for Tank Toilet show an attempt to provide automatic lowering by using sensors to automatically flush the toilet when the user leaves the sensor area and after flushing the toilet seat lowering is activated. Still, this is a costly and complex system.
- In the past flushing has been attempted by the traditional manual flush handle. A trip cord or a cord from the handle around behind the toilet to a ring on the wall was attempted in U.S. Pat. No. 6,233,751 titled Toilet Flushing and Seat Lifting System. A foot pedal with a mechanical link to the toilet flush handle was attempted in U.S. Pat. No. 6,651,262 titled Foot Operated Commode System. A switch to lower the toilet seat and toilet lid that would additionally engage a pulling rod to pull the toilet flush handle and flush the toilet was attempted in U.S. Pat. No. 4,055,864 titled Automatic Lid-Lifting and Flushing Device for Water Closet. A chain secured to a manual lifting device where the user pushed downward on the lifting device to actuate the flushing means was attempted in U.S. Pat. No. 5,829,067 titled Toilet Seat Lift Assembly. However, these systems required the user to remember to flush the toilet and to manually engage a pedal, switch, or cord. An infrared transmitter with sensor was attempted in U.S. Pat. No. 5,603,127 to provide automatic flushing when the user left the sensing area. Still, this was an expensive, complex device.
- There is a need for a device that: 1) will raise or lower a toilet seat without requiring a user to physically touch the seat, and further, will automatically lower the toilet seat and flush the toilet without any intervention from the toilet user after use; 2) is an inexpensive device; 3) is easy to install on most household or commercial toilets; 4) will not interfere with normal toilet operations; 5) is easy to use, for example, the user simply steps on pedal during time needed for seat to remain up, then user releases foot pressure which activates lowering seat and flushing; and 6) uses a 110/220 VAC motor.

- One embodiment of the present invention includes a kit installation. An example of a non limiting installation of a hands free toilet kit would comprise the following steps: The user may obtain the hands free toilet device as a kit. Referring to
FIG. 3 the user removes the existingstandard seat 12, installs thelift assembly 70 into the outer end of thedrive coupling 60, and folds thelift assembly 70 forward. The user positions the handsfree toilet device 20 mountingbase 22 over the seat fastening holes on top of the toilet bowl and reinstalls the existingstandard seat 12 with thelift assembly 70 positioned between the toilet bowl and thestandard seat 12 with thestandard seat 12 in the down position. Referring toFIG. 4 the user may remove the standardflush lever 14 mechanism and install the new hands freeflush lever 14 with a connection for theflush actuator connecter 82. The user would install theflush actuator connecter 82 between theflush lever 14 and theflush actuator 80. Referring toFIG. 1 the user may then position thefoot pressure actuator 50 on either side of thestandard toilet 10 as preferred. If using 110 Volt AC power, the user may plug in thepower cord 40 to an electrical wall outlet. The user will test the device by placing the user's foot on thefoot pressure actuator 50 and holding it there until thestandard seat 12 opens and stops at the open position. The user may remove his or her foot from thefoot pressure actuator 50 and thestandard seat 12 lowers to the closed position and then, as depicted inFIG. 4 , theflush actuator 80 continues rotation thereby pulling theflush lever 14 down using theflush actuator connector 82. Thestandard seat 12 and theflush lever 14 may operate independently of the automatic system. - As depicted in
FIG. 1 a method for the use of the handsfree toilet device 20 for raising and lowering astandard seat 12 includes stepping on thefoot pressure actuator 50 to raise thestandard seat 12, and releasing the foot from thefoot pressure actuator 50 to lower thestandard seat 12. One embodiment may include a flushing of thestandard toilet 10 during the releasing step by releasing the foot from thefoot pressure actuator 50 further flushing thestandard toilet 10. - (4) Uniqueness:
- As depicted in
FIG. 1 , the uniqueness of the present invention is illustrated in many ways, twelve of which are as follows. First, the handsfree toilet device 20 automatically lowersstandard seat 12 and flushes thestandard toilet 10. Second, the handsfree toilet device 20 is simple to install. Third, the handsfree toilet device 20 has a standard design that fits most conventional toilet designs. Fourth, the handsfree toilet device 20 is simple to operate: the user steps on thefoot pressure actuator 50 and then walks away when finished. Fifth, the handsfree toilet device 20 is a forgetful-proof device: you do not have to remember to lower thestandard seat 12 or flush thestandard toilet 10. Sixth, as depicted inFIG. 2 the handsfree toilet device 20 utilizes a low cost reversibleelectric gearmotor 32 and can be powered by 110 VAC which is readily available in almost every U.S. household. Seventh, the same reversibleelectric gearmotor 32 is used to actuate both thestandard seat 12 and the automaticflush actuator 80 depicted inFIG. 4 . Eighth, the handsfree toilet device 20 may be installed with or without the automatic flush feature. Ninth, thestandard seat 12 andflush lever 14 design do not interfere with normal, non-automatic, toilet operation. Tenth, there is no need to touch either thestandard seat 12 or theflush lever 14. Eleventh, thelift assembly 70 is fixed to thedrive coupling 60 in such a way that allows it to freely rotate upward. Thus, it allows an over-rotation of thedrive coupling 60 which is required to actuate theflush actuator 80 properly and it also serves as a safety feature so that the user should not be injured by thelift assembly 70 as it returns thestandard seat 12 to the closed position. Thestandard seat 12 is lowered in a controlled manner. Twelfth, the design of the handsfree toilet device 20 is inexpensive using standard components.
