DESCRIPTION

ERGONOMIC TOILET BOWL

The present invention relates to an ergonomic toilet bowl which is designed in a way that it provides the user who wishes to answer the call of nature to crouch with an appropriate crouching angle.

During digestion, the mixed foods going out of the stomach and the foods which are ready to be digested pass to the small intestine where the nutrients are absorbed, while the excrements go into the large intestine or colon. The state of the excrements when they come into the colon is liquid. While the excrements are progressing in the colon, the nutrients inside of them are absorbed and when they come to rectum, these excrements get solidified. The excrement, many nutrients inside of which are absorbed, becomes concentrated and this concentrated excrement is discharged from the anus. The excrements should be totally discharged from the body in order to prevent toxic accumulation and toxin generation in the inner structure. The discharge of the excrement from the body can only take place when the person crouches. During this crouching position, the upper front parts of the legs compress the stomach, which helps the excrement to move in the large intestines and to be discharged from the body easily. Cecum, ascending colon, tranverse colon, descending colon, sigmoid colon, rectum and anus are connected to the small intestine by means of ileocecal valve. Ileocecal valve acts as a one-way valve. While it allows the passage from the small intestine to the large intestine, it prevents any passage from the opposite direction. However, when the person is in a crouching position, the right femur compresses the cecum on the stomach and therefore helps the excrements move in the large intestine in an upward direction, which provides^' the appendicitis and ileocecal valve to stay clean. In order for the solid excrements coming to the sigmoid colon to progress without leaving residue and to be discharged from the anus by passing through the rectum, it is needed for them to overcome the sharp turn on the sigmoid colon. Sigmoid colon extends in a downward direction like an ovoid pouch on the intestine just before the anus. Thus, during the defecation process of a person, the excrement which is moving inside the intestine needs to overcome this obstacle. When the person takes a crouching position during the defecation process, the left femur compresses on the left part of the stomach and pushes the sigmoid colon to an upward direction. Therefore it becomes easier for the moving excrement inside the intestine to reach the anus by passing through the sigmoid colon.

In the large intestines, there is a valve also in the exit part just like in the entrance part. This valve is called as Puborectalis Muscle. Likewise this valve gets loose only during the crouching position and leaves the rectum inlet free. During the seating position, on the other hand, it holds the rectum outlet as a rubber in order to prevent accidental defecation. In order for a person to defecate during a seating position, he/she needs to overcome that valve and to strain to push that excrement out of the body.

In the state of art, there are different toilet bowl types and structures. The toilet bowls according to the state of art comprise a flat seating platform for the toilet bowl user to sit down and a resevoir which is vertically positioned on the upper surface of the seating platform, where the water to be used in the siphoning process is stored. In order for the said toilet bowls to be used, the user sits down vertically on the seating platform and uses the toilet. But the fact that the user answers the call of nature by sitting down vertically causes some basic health problems. When the person uses the toilet bowl forms which are positioned vertically, he/she answers the call of nature by sitting down in an upright manner. In the case that a person uses the toilet bowl forms which are vertically positioned, the human ergonomy, kneecap curve, leg and calf part form a 90°-100° angle. In this seating position, since the kneecap curve angle is 90° or more, the legs do not touch the stomach and the two femurs do not compress on the stomach. For this reason, the excrements cannot move from the small intestine to the large one in a healthy manner. Moreover, in the said seating position, the left femur do not compress on the left part of the stomach and therefore the sigmoid colon cannot be pushed in an upward direction, and as a result the excrements cannot progress towards the rectum. Likewise, when the kneecap curve angle is 90° or more, the valve which provides the excrement to be discharged from the anus does not opem

In this case, the person who uses the said toilet bowl systems which are positioned vertically needs to take a position which is called valsalva maneuver, in which the person uses inner stomach pressure to push the excrement out, or in other words he/she strains, in order to discharge the excrement. However in this position; hemorrhoid, capillary vessel chaps and lacerations emerge as a result of said excessive strains on the anus.

In the international patent application which is published with a publication number of WO2010/030242 within the state of art, a toilet bowl is described, which allows the user to sit down both backward and foreward. However in this said embodiment, the kneecap angle of the user is 90° or more. Thus the above-mentioned problems in terms of the discharge of the excrement cannot be prevented.

By using the inventive ergonomic toilet bowl, the toilet bowl user is provided to carry out the defecation process in a crouching position and therefore the health problems emerged as a result of vertical defecation are eliminated. By using the present invention, the person is provided to defecate both in a crouching position and to sit down at the same time.

The ergonomic toilet bowl according to the present invention is comprised of two main parts. The first part is the toilet base block (1) carrying the toilet block (2), while the other one is the toilet block (2) comprising the main functions and structure of the toilet. The ergonomic toilet bowl reservoir is designed together with the toilet block (2) as a monoblock structure so as to form one single structure .

The toilet base block (1) comprises a toilet back surface designed as a flat surface which is in contact with the wall at the back part of toilet block (2), and a toilet bottom surface designed as a flat surface connecting the toilet block extending vertically to the toilet back surface with the ground. Therefore, the toilet can easily be mounted onto the wall and ground. The toilet block (2) which is the other part is in the shape of an unproper bowl forming two different parabolic surfaces which gets separated from each other considering the middle point (5.2) of the toilet cover gap and which therefore have different extending inclinations from each other. When the middle point (5.2) of the toilet cover gap is accepted as a separating point, the part extending with a kind of stable and certain extending inclination which is left between the middle point (5.2) of the toilet cover gap and the back top (5.3) of the toilet cover gap is called as the primary parabolic surface; while the part extending with a kind of stable and certain extending inclination which is left between the middle point (5.2) of the toilet cover gap and the back top (5.3) of the toilet cover is called as the secondary parabolic surface. As it is shown in Figure 2, the extending inclinations of the primary and secondary parabolic surface are different from each other.

The extending inclination of the primary parabolic surface is stable itself. The extending inclination of the second parabolic surface, on the other hand, is stable to a certain extent; however, the front surface (5.4) of the toilet cover gap is located at the end part of the secondary parabolic surface which has different extending inclinations at the three end parts of the secondary parabolic surface.

As it is shown in Figure 2, when compared with the other surfaces, the extending inclination of the primary parabolic surface is higher, in other words, when the primary parabolic surface is accepted as a parabola arm part, the arms of the said parabola extend closer to each other. The extending inclination of the secondary parabolic surface, on the other hand, is lower compared to the extending inclination of the primary parabolic surface; in other words, when the secondary parabolic surface is accepted as a parabola arm part, the arms of the said parabola extend closer to each other. The extending inclination of the front surface (5.4) of the toilet cover gap which is located at the end part of the secondary parabolic surface, on the other hand, is lower than the above-mentioned two surfaces; in other words, when the front surface (5.4) of the toilet cover gap is accepted as an arm part, the arms of the said parabola extend with a more distance to each other compared to the other parabolas .

A toilet cover (4) is located on the upper part of the toilet block (2), in a way that it will be fitted into the toilet over gap (5). The toilet cover (4) is connected to the toilet framework cover (3) by means of a toilet cover hinge (6) . The toilet cover hinge (6) and the form of the toilet cover (4) are designed in a way that the back of the user sitting on the toilet will be pushed towards the front. In order to provide this structure, the toilet framework cover (3) extends to the upper part of the user's hip on the toilet cover gap (5) . A toilet cover hinge (6) is located on the point where the toilet framework cover (3) is ended on the surface; and a toilet cover (4) is located at the end part of the hinge where the toilet framework cover (3) has ended. While the toilet cover (4) starts by the hinge, it has a structure which forms a convex camber towards the front part of the toilet block (2) . This convex camber continues until nearly the middle part of the the reservoir cover (2.7) (when the toilet cover_. is in open position), and the convex form turns into a concave form towards the end part of the toilet cover (4) and finally a curve is created towards the end part of the toilet cover (2). Therefore, when the toilet cover (2) is closed, the toilet cover is fitted into the gap and when the user sits on the toilet when the toilet cover is open, the convex camber form on the toilet cover (4) pushes the back of the user to the front, and therefore the person using the toilet can perform the defecation process with an optimal sitting angle.

The above-mentioned toilet block (2) , characterized in that in order for the person to take a crouching position, the parabolic semi-cavity (the primary parabolic surface) extending to the back top (5.3) of the toilet bowl and gradually ascending in a parabolical manner from the midpoint (5.2) of the toilet cover block needs to have such an inclination which is enough to keep the upper part of one's hips above and which is higher compared to the other parabolic cavities, and the other parabolic semi-cavity extending to the front top (5.1) of the toilet cover from the mid-point (5.2) of the toilet cover gap extend with lower extending inclination compared to the other one; the back part of the user should be kept inclined to the front by providing again a similar structure on the toilet cover (4); the parabolic semi-cavity gradually ascending in a parabolical manner from the mid-point (5.2)of the toilet cover gap and extending towards the front surface (5.4) of the toilet cover gap stretches one's calf starting from the hip to the knee cap with a slight inclination and pushes the upper part of one's calf to the calfs, and therefore by means of the parabolic structure of different inclinations inside the two semi-cavities and the toilet top protrusion, the angle between the knee-curve and the calf part is 40°-45°. The seating line of the toilet bowl necessary for the defecation process by crouching is 40°- 45° in avarage.

In order for providing the angle between the above- mentioned knee-curve of 40-45° and the calf part, the shape and form of the toilet block (2) and toilet cover (4) are designed in the above-mentioned manner; however it is not enough to provide the desired sitting angle. In order to provide the necessary sittinh angle, the toilet block (2) and the toilet base block (1) need to be arranged as well. Therefore, preferably the lenght between the middle point of the toilet cover gap and the front top of the toilet cover (A) is 320 mm; the length between the middle point of the toilet cover gap and the toilet base (B) is 200-250 mm; the lateral length (C) of the middle point of the roilet cover gap is 325 mm; the lateral length (D) of the middle point of the back top of the toilet cover is 345 mm; the length between the front top of the toilet cover gap and the toilet base (E) is 320-350 mm; the length between the back top of the toilet cover gap and the toilet base

(F) is 610 mm and the length between the front top of the toilet gap and its surface in contact with the back wall

(G) is 740 mm.

An ergonomic toilet bowl according to the present invention can also be designed by using different measurements than the ones mentioned above which will provide the same ratio, in a way that the toilet form and shape will remain same. The above-mentioned sizes are the measurements which have been priorly prepared in a way to describe a certain ratio. The alternative embodiments of the present invention can be applied for different models by using different sizes to create the same ratio on condition that toilet form and shape will remain as it is. The ergonomic toilet bowl according to the present invention comrpises a toilet chamber gap (2.1) which is located inside the body at the bottom part of the toilet cover gap (5) in a way to create a bowl-form chamber, a washing channel gap (2.4) located on the front part of the toilet chamber gap (2.1), a toilet drain part (2.2) connected to a hole on the ground of the toilet chamber gap (2.1) at the bottom part of the toilet chamber gap (2.1) a toilet drain outlet (2.3) located on the ground of the toilet base block (1) which is in connection with the toilet drain part (2.2), a toilet water tank chamber (2.5) located as a complementary part embedded inside the toilet block at the back part of the toilet block (2), a reservoir cover (2.7) located on the upper part of the toilet water tank chamber (2.5), and a washing channel connection (2.6) located at the bottom part of the toiley water chamber (2.5) .
