Technical Field
Engineering related to toilets Background Art
Toilets that are currently manufactured and commercially available can be classified into 6 different types.
1) One-piece toilet
2) Two-piece toilet
3) Flush valve toilet
4) Wall hung toilet
5) Wall faced toilet
6) Pail flush toilet
Conventional toilets comprise 7 main components as follows (as shown in FIGURES. 1-3)
1) Toilet bowl (1). Used for defecation and urination, toilet bowls can be made of ceramic, or metal, or plastic, or any synthetic materials. Conventionally shaped as a bowl, a toilet bowl can be fixed to the floor or hung on the wall, and feature a horizontal top opening (6) in the middle.
2) Toilet tank (2). Containing flush water that cleans the toilet bowl after defecation and urination, the toilet tank is located on the horizontal top behind the toilet bowl opening (6) and in a position above the toilet. Usually made of the same material as the toilet bowl, a toilet tank, together with the toilet bowl, can be manufactured in one piece or in two separate pieces.
3) Two holes (3). These two holes are inserted with expansion anchors, which, in turn, secure pintles, screws, or bolts and nuts that fasten a toilet seat and lid lifting/lowering device to the toilet bowl. Conventionally, these two holes (3) are drilled perpendicularly to the horizontal top rim (7) of the toilet bowl opening (6) near the lower part of the toilet tank (2).
4) Toilet seat (4). A toilet seat is a lid with an opening in the middle and is seated upon by users. Made of plastic, wood, or other synthetic materials, it is conventionally shaped as an oval or a trapezoid 5) Toilet lid (5). Used to covering the toilet seat and the toilet bowl, a toilet lid is usually oval or trapezoid in shape and made of plastic, wood, or other synthetic materials. In addition, the toilet seat (4) and the toilet lid (5) can be lifted and lowered to reveal or cover the toilet bowl opening. These two pieces of equipment are fastened to a lifting/lowering device, which is, in turn, secured to the toilet bowls where the two holes (3) are located. Both pieces of equipment rest on the top rim (7) of the toilet bowl opening (6).
6) Toilet bowl opening (6). A receptacle receiving bodily wastes before being passed down to a S-trap or a P-trap, a toilet bowl opening is an oval or trapezoid aperture in the middle of the toilet bowl (1) with a rim (7) that defines the bowl opening.
7) Rim of the toilet bowl opening (7). The rim of the toilet bowl opening is the horizontal top surface around the toilet bowl opening (6) and is rested upon by a toilet seat (4).
Apart from the 6 types of toilets described above, toilets can be classified by their means of waste disposal into 2 kinds as follows.
1) S-trap toilet (as shown in FIGURE. 4). This type of toilet features an S-shaped bend that is attached to the drain pipe under the toilet bowl (1) that goes into the ground (14).
2) P-trap toilet (as shown in FIGURE. 5). This type of toilet features a P-shaped bend that is attached the drain pipe behind the toilet bowl (1) that goes into the wall (15).
All the aforementioned toilet models are susceptible to the following deficiencies.
1) Difficulties often arise in the cleaning of the area around the two vertical holes (3) in the rear portion of the horizontal top rim (7) near the lower part of the toilet tank (2) that are used to secure pintles, or screws, or bolts and nuts; or any apparatuses that secure a hinge axis; or any toilet seat (4) and lid (5) lifting/lowering devices (8). The recesses created by these pieces of equipment are mostly inaccessible and present a challenge in cleaning.
2) The current designs result in the accumulation of the water used in cleaning the toilet bowl and the water from the use of a spray hose after defecation on the rim (7) of the toilet bowl opening (6) in the recesses around the two holes (3) which are mostly inaccessible and hard to clean thoroughly. Features and Objectives of the Invention
This present invention (as shown in FIGURES. 6-32) relates to the relocation of the two holes or of the mounting position for any devices that secure pintles, or screws, or bolts and nuts; or for any apparatuses that secure a hinge axle; or for any toilet seat and lid lifting/lowering devices. Conventionally, these two holes are vertical and located near the lower part of the toilet tank in the rearward portion of the horizontal top rim surface defining the toilet bowl opening.
In a toilet of the present invention, these two holes become horizontal and are moved to be located on the wall of the support base beneath the toilet tank; or on the lower part of the wall of the toilet tank; or on the wall of any raised base, ridge, sloped platform, or curved platform beneath the toilet tank. Said wall can be perpendicular to at any angle to the horizontal top rim of the toilet bowl opening (as shown in FIGURES.24-31).
Main Objectives
When applied to the 12 types of toilets currently manufactured and commercially available, which will be described in detail below, the aforementioned invention will result in a more practical toilet.
1) The length of the new toilet will be shortened by the width of the hinge, the axle, or the toilet seat and lid lifting/lowering device. This is due to the relocation of the two holes or of the mounting positions for any devices that secure pintles, or screws, or bolts and nuts; or for any apparatuses that secure a hinge axis; or for any toilet seat and lid lifting/lowering devices to be fastened to the toilet bowl. When moved to be located on the lower part of the wall of the toilet tank or on the wall of any raised base, ridge, sloped platform, or curved platform beneath the toilet tank, whether said wall is either perpendicular to or inclined to the horizontal top rim of the toilet bowl opening, the two holes in this new invention, which are now horizontal, no longer take the space in the rearward portion of the horizontal top rim near the lower part of the toilet tank and, thereby, shorten the length of the toilet. As the toilet becomes smaller in size and takes less space, the size of the space or the room in which the new toilet is to be installed can, in turn, be reduced.
2) This new toilet can be cleaned with greater ease and efficiency because the rearward portion of the horizontal top rim is devoid of the two holes and any devices that secure a hinge axle or an axle of a toilet seat and lid lifting/lowering device, all of which create recesses that are difficult to clean thoroughly.
Disclosure of Invention
The toilets of the present invention include two types of toilets, namely S-trap toilets (as shown in FIGURE. 4) and P-trap toilets (as shown in FIGURE. 5). Each type can be further classified into 6 more subtypes as delineated below, resulting in 12 toilet types altogether.
1) One-piece toilet (as shown in FIGURES. 6-8)
2) Two-piece toilet (as shown in FIGURES. 9-11)
3) Flush valve toilet (as shown in FIGURES. 12-14)
4) Wall hung toilet (as shown in FIGURES. 15-17)
5) Wall faced toilet (as shown in FIGURES. 18-20)
6) Pail flush toilet (as shown in FIGURES. 21-23)
All the twelve toilet types of the present invention are distinguished from toilets that are currently commercially available by the position of the two holes or the mounting position (3) for pintles, screws, or expansion bolts that fasten a hinge axle or a toilet seat (4) and lid (5) lifting/lowering device (8) to the toilet bowl (1). Conventionally vertical and drilled in the rearward portion of the horizontal top rim (7) defining the toilet bowl opening (6) near the lower part of the tank (2), the two holes (3) of this invention are horizontal and relocated to the wall of any raised base, ridge, sloped platform, or curved platform (13); or to the wall of the support base beneath the toilet tank (10); or to the lower part of the wall of the toilet tank (11), whether said wall is perpendicular to or inclined to the horizontal top rim surface (7) defining the toilet bowl opening (6). The shapes, sizes, and characteristics of the two holes (3) of the currently available toilet, as well as their function in securing a toilet seat (4) and lid (5) lifting/lowering device (8), will be retained in the toilet of this present invention. 1) FIGURES. 6-8 show the top plan view, the front view, and the side view of a one-piece toilet. In the toilet of the present invention, the two holes or the mounting positions (3) for a toilet seat (4) and lid (5) lifting/lowering device (8) are located behind the toilet bowl opening (6) near the lower part of the toilet tank (2). These two holes (3) are horizontal and located on the lower part of the wall of the toilet tank (2) or on the wall of a raised support base or ridge (10) under the water tank, whether said wall is perpendicular to or at an angle to the horizontal top rim surface (7) defining the toilet bowl opening (6). In addition, the raised support base or ridge can be flush with the toilet tank (as shown in FIGURE. 29) or extend from the toilet tank (as shown in FIGURE. 32).
2) FIGURES. 9-11 show the top plan view, the front view, and the side view of a two-piece toilet. In the toilet of the present invention, the two holes or the mounting positions (3) for a toilet seat (4) and lid (5) lifting/lowering device (8) are located behind the toilet bowl opening (6) near the lower part of the toilet tank (2). These two holes (3) are horizontal and located on the wall of any raised base, ridge (as shown in FIGURES. 24-25), sloped platform (as shown in FIGURES. 26-27), or curved platform (as shown in FIGURES. 28) beneath the toilet tank, whether said wall is perpendicular to or at an angle to the horizontal plane. In addition, the raised base, ridge, sloped platform, or curved platform can be flush with the toilet tank (as shown in FIGURES. 29) or extend from the toilet tank.
3) FIGURES. 12-14 show the top plan view, the front view, and the side view of a flush valve toilet.
4) FIGURES. 15-17 show the top plan view, the front view, and the side view of a wall hung toilet.
5) FIGURES. 18-20 show the top plan view, the front view, and the side view of a wall faced toilet.
6) FIGURES. 21-23 show the top plan view, the front view, and the side view of a pail flush toilet.
In the latter four types of toilets of the present invention mentioned above (as shown in FIGURES. 12-23), the two holes or the mounting positions (3) for a toilet seat (4) and lid (5) lifting/lowering device (8) are located behind the toilet bowl opening (6). These two holes (3) are horizontal and located on the wall of a base or ridge (as shown in FIGURES. 24-25, but without the toilet tank (2)), or a sloped platform (as shown in FIGURES. 26-27, but without the toilet tank (2)) that is raised from the rear portion of the horizontal top rim (7) defining the toilet bowl opening (6), whether said wall is perpendicular to or at an angle to the horizontal top rim surface. The raised base, ridge, sloped platform, or curved platform (13), which bears the two holes (3), can be made of either the same material as the toilet bowl or different materials. In addition, the raised base, ridge, or platform (13) can be in any shape and can take either the whole area or a partial area of the rear portion of the horizontal top surface behind the toilet bowl opening. The width or the height of the wall of the base, ridge, sloped platform, or curved platform; or of the wall of the support base (10) beneath the toilet tank; or of the lower part of the toilet tank wall (11) that bears the two holes (3) for securing a toilet seat (4) and lid (5) lifting/lowering device (8) depends on the width of the hinge or the a toilet seat (4) and lid (5) lifting lowering device (8) itself.
The techniques and the processes employed in the manufacturing of the currently available toilet can be readily applied to all the 6 subtypes of toilets, whether they feature a P-trap or an S-trap. In addition, experts on ceramic, metals, plastic, or other synthetic materials can be called upon to improve the durability of the wall part that bears the two holes or the mounting positions (3) at which the toilet seat (4) and lid (5) lifting/lowering device is fastened to the toilet bowl (1) so that they can support the weight of the user and the weight of the toilet seat (4) and lid (5) assembly, as well as withstand the impact caused when the toilet seat (4) and the toilet lid (5) are lifted or lowered (as shown in FIGURES. 6-32). Also, toilet seat (4) and lid (5) experts can be called upon to design means of fastening a lifting/lowering device (8) and a hinge, along with the toilet seat (4) and the toilet lid (5), to the two horizontal holes (3) on a vertical or slanting wall instead of the conventional vertical holes (3) on a horizontal top rim (7) of the toilet bowl opening (6).
