Description
Background of the Invention
1. Field of the Invention
The present invention relates to power operated doors and more particularly pertains to a new automatic bathroom door and toilet flushing system for automatically raising the door and flushing the toilet when a user is finished.
2. Description of the Prior Art
The use of power operated doors is known in the prior art. More specifically, power operated doors heretofore devised and utilized are known to consist basically of familiar, expected and obvious structural configurations, notwithstanding the myriad of designs encompassed by the crowded prior art which have been developed for the fulfillment of countless objectives and requirements.
Known prior art power operated doors include U.S. Pat. No. 4,274,227 to Toenjes; U.S. Pat. No. 4,956,938 to DeMent; U.S. Pat. No. 5,247,232 to Lin; U.S. Pat. No. 4,575,880 to Burgess; U.S. Pat. No. 5,353,443 to Sim; and U.S. Pat. No. Des. 283,923 to Henry et al.
While these devices fulfill their respective, particular objectives and requirements, the aforementioned patents do not disclose a new automatic bathroom door and toilet flushing system. The inventive device includes a housing secured to a ceiling between a pair of walls. The housing has an opening in a lower end thereof. A door is rotatably disposed within the housing. The door is disposed on a central shaft. The central shaft is coupled with an electric motor. The electric motor selectively raises and lowers the door with respect to an opening between the pair of walls. An electric sensor is in communication with the electric motor and an electrical system of an existing toilet. The electric sensor is disposed within one of the pair of walls adjacent to the handle of the manual pulley system.
In these respects, the automatic bathroom door and toilet flushing system according to the present invention substantially departs from the conventional concepts and designs of the prior art, and in so doing provides an apparatus primarily developed for the purpose of automatically raising the door and flushing the toilet when a user is finished.
Summary of the Invention
In view of the foregoing disadvantages inherent in the known types of power operated doors now present in the prior art, the present invention provides a new automatic bathroom door and toilet flushing system construction wherein the same can be utilized for automatically raising the door and flushing the toilet when a user is finished.
The general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new automatic bathroom door and toilet flushing system apparatus and method which has many of the advantages of the power operated doors mentioned heretofore and many novel features that result in a new automatic bathroom door and toilet flushing system which is not anticipated, rendered obvious, suggested, or even implied by any of the prior art power operated doors, either alone or in any combination thereof.
To attain this, the present invention generally comprises a housing secured to a ceiling between a pair of walls. The housing has an opening in a lower end thereof. A door is rotatably disposed within the housing. The door is disposed on a central shaft. The central shaft is coupled with an electric motor. The electric motor selectively raises and lowers the door with respect to an opening between the pair of walls. A manual pulley system is disposed within one of the pair of walls. The manual pulley system includes an upper pulley and a lower pulley. A cable extends between the upper and lower pulley and the central shaft of the door. The pulley system includes a pivotable handle extending outwardly of the wall. The handle is coupled with the lower pulley whereby rotation of the handle will rotate the pulley thereby raising or lowering the door with respect to the opening between the pair of walls. An electric sensor is in communication with the electric motor and an electrical system of an existing toilet. The electric sensor is disposed within one of the pair of walls adjacent to the handle of the manual pulley system. A plurality of supplemental sensors are in communication with the electric motor. The supplemental sensors are disposed within one of the pair of walls adjacent to the door. The supplemental sensors, when activated, would stop lowering of the door with respect to the opening between the pair of walls.

Description of the Preferred Embodiment
With reference now to the drawings, and in particular to FIGS. 1 through 4 thereof, a new automatic bathroom door and toilet flushing system embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described.
As best illustrated in FIGS. 1 through 4, the automatic bathroom door and toilet flushing system 10 comprises a housing 12 secured to a ceiling between a pair of walls 14. The housing 12 has an opening in a lower end thereof.
A door 16 is rotatably disposed within the housing 12. The door 16 is disposed on a central shaft 18. The central shaft 18 is coupled with an electric motor 20. The electric motor 20 selectively raises and lowers the door 16 with respect to an opening between the pair of walls 14. Alternately, a concertina door could be provided that would fold up within the housing 12 when not in use. A concertina type door 16 could also fold into the housing 12 which is mounted in a vertical fashion on one of the pair of walls 14.
A manual pulley system is disposed within one of the pair of walls. The manual pulley system includes an upper pulley 22 and a lower pulley 24. A cable 26 extends between the upper and lower pulley 22, 24 and the central shaft 18 of the door 12. The pulley system includes a pivotable handle 28 extending outwardly of the wall 14. The handle 28 is coupled with the lower pulley 24 whereby rotation of the handle 28 will rotate the pulley 24 thereby raising or lowering the door 16 with respect to the opening between the pair of walls 14.
An electric sensor 30 is in communication with the electric motor 20 and an electrical system of an existing toilet. The electric sensor 30 is disposed within one of the pair of walls 14 adjacent to the handle 28 of the manual pulley system.
A plurality of supplemental sensors 32 are in communication with the electric motor 20. The supplemental sensors 32 are disposed within one of the pair of walls 14 adjacent to the door 16. The supplemental sensors 32, when activated, would stop lowering of the door 16 with respect to the opening between the pair of walls 14.
In use, the standard side-hung door currently employed for washrooms would be replaced by the housing 12 and the door 16. The electric sensor 30 located within the side wall 14 would cause the door 16 to automatically close immediately after an individual occupied the washroom. The door 16 would slide down guide rails attached to the side walls 14 of the washroom and would be aided by the electric motor 20. When an individual was finished using the washroom, he or she would activate the electrical sensor 30 again. Along with signaling the motor 20 to raise the door 16, the sensor 24 would cause the toilet to be flushed, thus ensuring it would be clean for the next user. The door 16 would remain open until another person entered the washroom. The toilet may also be flushed without opening the door 16. The supplemental sensors 32 are provided to prevent injury to an individual who may have activated the electric sensor 24 but was not entirely within the washroom. The supplemental sensors 32 would be installed at heights corresponding with leg level, arm level and upper body levels of an individual. Any activation of the supplemental sensors 32 would cause the door 16 to stop lowering. As soon as the supplemental sensor(s) 32 was unobstructed, the door 16 would resume closing. A warning buzzer or flashing light could be used to alert the individual of the obstruction. In the event of an electrical failure, the individual could operate the manual pulley system in order to raise the door 16 and exit the washroom. The pivotable handle 28 could be provided within a seal enclosure that could be broken to allow the user to manipulate the handle 28.
The present invention would also include a toilet paper dispenser 34 secured to one of the pair of walls 14 opposite from the electric sensor 30 and the manual pulley system. Additionally, a clothes hook 36 would also be provided on one of the walls to allow a user to hang items of clothing therefrom.
As to a further discussion of the manner of usage and operation of the present invention, the same should be apparent from the above description. Accordingly, no further discussion relating to the manner of usage and operation will be provided.
With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.
Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
