The present invention relates generally to a toilet having multiple foot placement positions, and more particularly to a toilet module having multiple foot placement positions for use in an aircraft lavatory.
Commercial aircraft, such as the Airbus A320 or Boeing 737, are typically constructed from modular components, the size, weight and construction of which are dictated by many considerations, including fuselage dimensions, aesthetic and safety. Many of these requirements are imposed by law or regulation. Aircraft components, such as overhead stowage compartments, seats, lavatories, galleys, lighting systems, etc. are all required to function within strictly confined spaces.
Manufacturers of aircraft are constantly refining interior aircraft designs to achieve more comfort and utility for passengers and crew within carrier-imposed restraints on cost, weight, maintenance down-time, and safety. Commercial passenger aircraft generally include lavatories for use by passengers and crew that include a toilet therein. There are a surprisingly large number of countries and cultures in Asia, the Middle East and Africa where squatting toilets are a part of daily life. The locations where squat toilets easily outnumber sitting toilets include the two most populous countries in the world today: China and India. In many other countries squat toilets can be found in large numbers, especially in public places, as in public transportation. It is estimated that more than 3.5 billion people around the world are using the squatting position every day.
In accordance with a first aspect of the present invention there is provided a toilet assembly that includes a shroud portion, a main body portion extending generally forwardly from the shroud portion, and first and second intermediate protrusions extending generally forwardly from the bowl portion. The main body portion includes a bowl portion that includes a bottom and a top. The top includes an upper surface that defines a seat adjacent surface. The first and second intermediate protrusions are located vertically between the top and the bottom of the bowl portion and are configured such that a user can position their feet thereon. In a preferred embodiment, the first and second intermediate protrusions each include an upper surface that defines an intermediate position surface that is generally horizontal.
In a preferred embodiment, the bowl portion further includes first and second squat extension portions extending outwardly therefrom that each include an upper surface that defines a squat position surface that is generally horizontal. Preferably, the bowl portion includes a generally ring-shaped seat adjacent surface and the squat position surfaces extend outwardly from the seat adjacent surface. In a preferred embodiment, the squat position surfaces include front and outer edges that are generally perpendicular to one another and the first and second squat extension portions include a front surface and an outer surface that are generally perpendicular to one another.
In a preferred embodiment, the first and second intermediate protrusions are separate from one another. In another embodiment, they can be a single protrusion that includes a common surface with two places for the user's feet. Preferably, the first and second squat extension portions include tread portions thereon. The tread portions can extend from the squat position surface to the seat adjacent surface.
In accordance with another aspect of the present invention there is provided toilet assembly that includes a shroud portion, and a main body portion extending generally forwardly from the shroud portion. The main body portion includes a bowl portion that includes a bottom and a top. The top includes an upper surface that defines a seat adjacent surface, and the bowl portion further includes first and second squat extension portions extending outwardly therefrom. The first and second squat extension portions each include an upper surface that defines a squat position surface that is generally horizontal. In a preferred embodiment, the bowl portion includes a generally ring-shaped seat adjacent surface and the squat position surfaces extend outwardly from the seat adjacent surface. Preferably, the squat position surfaces include front and outer edges that are generally perpendicular to one another and the first and second squat extension portions include tread portions thereon. In a preferred embodiment, the tread portions extend from the squat position surface to the seat adjacent surface.
In a preferred embodiment, the toilet assembly further includes first and second intermediate protrusions extending generally forwardly from the bowl portion. that are located vertically between the top and the bottom of the bowl portion. The first and second intermediate protrusions are configured such that a user can position their feet thereon. Preferably, the first and second intermediate protrusions each include an upper surface that defines an intermediate position surface that is generally horizontal.
In accordance with another aspect of the present invention, there is provided a toilet seat assembly that includes a pivotable cover, and a pivotable seat that includes a ring portion that defines a seat surface and first and second squat extension portions extending outwardly from the ring portion. The first and second squat extension portions each include an upper surface that defines a squat position surface that is generally horizontal. In a preferred embodiment the seat and cover are pivotable along the same pivot axis.
Preferably, the squat position surfaces include front and outer edges that are generally perpendicular to one another. In a preferred embodiment, the first and second squat extension portions include a front surface and an outer surface that are generally perpendicular to one another. Preferably, the first and second squat extension portions include tread portions thereon. The tread portions preferably extend from the squat position surface to the seat surface.
In the present invention, generally, footstep provisions are integrated into the toilet and or an additional squat toilet ring (similar to a traditional toilet seat yet specialized for squatting). In an embodiment, the invention includes safety handles (assist handles) located in such a way that they are in reach while using the squat provisions or footsteps.
The present invention is a toilet that includes provisions for a person to use the toilet with their feet in two or three different positions. The first position being the regular use/sitting position (typical in western-style toilets), the second being the sitting position with raised legs (referred to herein as the “intermediate position” or the “squatty potty” position) and the third being the squatting position (typically used in toilets in countries such as India). Some of the different positions can provide use of the toilet without sitting on the seat and use of toilet while seated while legs are elevated from the floor. Furthermore, the invention can include built in safety features, such as handles and braces. In a preferred embodiment, the toilet assembly is used in an aircraft lavatory. In different embodiments, the platforms for the user's feet can be positioned on the toilet itself, on the toilet seat or a combination thereof.
In a first preferred embodiment, the toilet shroud includes squat provisions integrated therein. Provisions are such that it has structural reinforcements to allow people of percentiles (of weight) to safely use them. Structural reinforcements may be incorporated underneath the shroud to transfer the loads while in use. In a preferred embodiment, integrated anti-slip provisions are included. The shape allows for use in the squat position, the raised legs position (the intermediate position) and regular use. In another embodiment, only one of the provisions set (for the squat position or the intermediate position) can be included.
In another preferred embodiment, the toilet includes an additional squat “seat” or intermediate seat/ring that is pivotal and located between the standard toilet seat and the toilet rim. The toilet can also be used in the squat position (by standing on the intermediate seat/ring) or by lowering the standard toilet seat to use while seated.
The additional squat seat can have structural reinforcements or it can be manufactured from a strong enough material to allow people of percentiles to safely use it. Structural reinforcements can be incorporated underneath the existing shroud to transfer the loads while in use. Integrated anti-slip provisions or tread members or portions can be included.
Assist handles on the walls or doors of the lavatory can be included. The location of the handle(s) are not limiting, but will preferably be located on the walls for hand-holds to ensure safety while either squatting on top of the squat seat or shroud squat provisions. Handles can be used when squatting and/or they will be within easy reach to the person if needed when turbulence occurs in flight.
Described herein is a preferred embodiment of a toilet and shroud that include multiple foot placement positions. In a preferred embodiment, the toilet is used in an aircraft lavatory. However, this is not a limitation on the present invention, and the description herein of the toilet being used in an aircraft is only exemplary. In a preferred embodiment, the toilet assembly can be used with the attachment assembly taught in U.S. Pat. No. 9,896,213, issued on Feb. 20, 2018, the entirety of which is incorporated by reference herein.
