Description

SYSTEM PROVIDING SLOW CLOSURE FOR THE TOILET LOWER AND UPPER COVERS AND THE TOILET LOWER AND UPPER COVERS HAVING SUCH SYSTEM

Subject of the Invention

The invention relates to a system developed for the toilet lower and upper covers for providing slow closure for said covers and to the toilet lower and upper covers having such system.

State of the Art

During the closing movements of the toilet covers, a disturbing noise is generated due to such covers closing in an uncontrolled and fast manner and the user needs to close the cover by holding it in order to prevent such movement. However, this results in the inconvenience of use for the user and causes the user to contact the cover for a longer period of time.

Numerous systems have been developed with a view to solve said problem. In some of the systems developed, the friction is generated during the movements of the covers and the movements of the covers are slowed down with the help of the shafts mounted to the covers and the mechanism feet to which the shafts are mounted vertically. However, since the movement is slowed down due to the friction in the systems obtained in this way, the wear develops in time in the parts that provide the friction and such parts are required to be replaced.

Object of the Invention

An object of the invention is to develop a system enabling the upper cover and lower cover of a toilet to close slowly. Another object of the present invention is to develop a system, which enables the lower cover and upper cover of a toilet to close slowly owing to a fluid added into the body present within the system.

Detailed Description of the Invention

The parts of the slow closure system according to the invention can be seen in Figures 1 and 1 1 . The slow closure system comprises at least one main body (4), at least one rotor (2) to be positioned within the main body (4) and at least one sweeper flap (3) to be positioned on said rotor (2).

Said rotor (2) can be seen in Figure 2. The rotor (2) comprises at least one rotor body (14), the side wings (10) arranged on the rotor body (14) such that two side wings are positioned on each side of the body in an opposing manner and the slots (10a) formed between said side wings (10) positioned on each side of the rotor body (14). Said sweeper flap (3) is positioned within said slot (10a). While a tab (3a) may be positioned on the sweeper flap (3), it is also possible within the scope of the invention for the same to have a structure without any tab. The sweeper flap (3) having a structure without any tab can be seen in Figure 25 and the sweeper flap (3) with a tab can be seen in Figure 26. Said tabs (3a) form protuberant sections on the surface of the sweeper flap (3) wherein there are present between said tabs (3a) the fluid passage surfaces (3b), which are disposed at a level lower than said tabs (3a). In the form of the sweeper flap (3) that does not contain a tab (3a), the passage of the fluid during the opening of the cover occurs more easily as compared to a sweeper flap (3) with a tab (3a).

At least one connection member (12) is positioned on the rotor body (14), wherein said connection member (12) has already been fixed on the rotor body (14) according to the preferred embodiment, but it is also possible to fix the same on the rotor body (14) at a later time. The mounting of the rotor (2) inside the main body (4) is realized by means of at least one bearing member (6), bearing upper piece (7), washer (8) and nut (9). A sectional view of the rotor (2) in a state mounted inside the main body (4) can be seen in Figure 7. As can be seen in Figure 7, the sealing members (1 ) are positioned on the rotor (2). One of the sealing members (1 ) is positioned on at least one sealing member seating surface (1 1 ) on the rotor (2), while the other is positioned in front of the bearing member (6) as seen in Figure 7. Said sealing members (1 ) are preferably in the form of o-rings, but the use of different forms of sealing members is also possible within the scope of the invention. While the rotor (2) is being fixed within the main body (4), some amount of a fluid (16) with certain viscosity is also added to the inner surface of the main body (4). The closing movements of the cover are controlled via the motion of said fluid (16).

There are present at least two inner wings (15) positioned in an opposing manner on the inner surface of the main body (4), wherein said inner wings (15) extend into the main body (4) to contact the rotor (2) positioned within the main body (4). In this way, in the state in which the cover is closed, there are present at least two partitions within the main body (4), shown as the partition "b" (b) and the partition "x" (x), which contain the fluid (16). This can be seen in Figure 20. On the other hand, in the state in which the cover is open, there are again at least two partitions present within the main body (4), wherein said partitions are shown as the partition "y" (y) and the partition "a" (a) as seen in Figure 22. The state during the opening movement of the cover can be seen in Figure 21 . The partition "a" (a) and the partition "y" (y) start to form. However, during the closing movement of the cover shown in Figure 19, the partition "b" (b) and the partition "x" (x) are formed. The channels (13) are positioned on the rotor (2), through which the passage of the fluid (16) will be provided between said partitions in the manner as will be described below in more detail. Similarly, the body channels (19) are positioned on the main body (4). The opening and closing movements of the cover and the passage of the fluid (16) between said partitions are described below in more detail.

The open position of the cover can be seen in Figure 22 and the closed position of the cover can be seen in Figure 20. The passage of the fluid (16) occurring between the partitions while the cover is closing can be seen in Figure 19 and the passage of the fluid (16) occurring between the partitions while the cover is opening can be seen in Figure 21 . As can be seen in Figure 22, the partition "b" (b) and the partition "x" (x) almost disappear when the cover is open. When it is desired to bring the cover from the open position into the closed position, the cover is moved in the closing direction (17) and meanwhile, as can be seen in Figure 19, the passage of the fluid (16) occurs from the partition "a" (a) to the partition "b" (b), which is formed by the rotational movement of the cover and which spreads over an increasingly greater area, and also from the partition "y" (y) to the partition "x" (x), which is formed again by the movement of the cover along the closing direction (17). When the cover is in open position, the sweeper flap (3) contacts the inner surface (4c) of the main body, as can be seen in Figures 23 and 24. For this reason, the passage of the fluid (16) through said partitions during the closing movement of the cover occurs via the channels (13) on the rotor (2) and the body channels (19) on the main body (4). The passage of the fluid (16) through the channels (13) on the rotor (2) during the closing movement of the cover can be seen in Figure 24 and the passage of the fluid (16) through the body channels (19) on the main body (4) during the closing movement of the cover can be seen in Figure 23. As can be seen in Figure 23, because the sweeper flaps (3) abut against the inner surface (4c) of the main body (4) when the cover is in open position, the passage of the fluid (16) does not take place through the fluid passage surfaces (3b) in case the sweeper flaps (3) contain tabs (3a) or through the surface of the sweeper flaps (3) in case the sweeper flaps (3) do not contain tabs (3a), during the closing movement. The movement of the cover in turn takes place slowly in a manner dependent upon this condition. Accordingly, the cover is enabled to close slowly while it is performing the closing movement.

The state of bringing the cover from the closed position into the open position can be seen in Figure 21 , wherein the passage of the fluid (16) occurs from the partition "b" (b) to the partition "a" (a) and from the partition "x" (x) to the partition "y" (y) and the initial movement is realized by means of the lifting force applied by the user. When the cover is in closed position, the partition "a" (a) and the partition "y" (y) almost disappear as seen in Figure 20 and these are formed upon the cover starting move in the opening direction (18). The fact that the passage of the fluid (16) is more rapid since the passage of the fluid (16) occurs through the channels (13) positioned on the rotor (2), the body channels (19) positioned on the main body (4) and the fluid passage surfaces (3b) positioned on the sweeper flaps (3) during the opening movement of the cover speeds up the movement of the cover, enabling the same to open more easily. In case of using the sweeper flaps (3) with no tabs (3a), the passage of the fluid (16) may take place more easily as said passage would be able to occur through the entire surface of the sweeper flap (3). The passage of the fluid (16) through the body channels (19) and the fluid passage surfaces (3b) on the sweeper flaps (3) during the opening movement of the cover can be seen in Figure 17. The passage of the fluid (16) through the channels (13) positioned on the rotor (2) and the fluid passage surfaces (3b) on the sweeper flaps (3) during the opening movement of the cover can be seen in Figure 18. The inner wings (15) on the main body (4) contact the rotor (2) and owing to said inner wings (15), no passage of fluid (16) occurs between the partition "b" (b) and the partition "y" (y) or between the partition "a" (a) and the partition "x" (x).

The slow closure system developed within the scope of the invention is used both for the lower cover and the upper cover of a toilet. The rectangular protuberant structures (5) to be positioned on the main body (4) are positioned on the neck region (4a) of the main body (4), as can be seen in Figure 1 1 , in case of using the slow closure system according to the invention for a toilet upper cover, whereas they are positioned on the body region (4b) of the main body (4), as can be seen in Figure 1 , in case of using the slow closure system according to the invention for a toilet lower cover. Said rectangular protuberant structures (5) are positioned into their respective slots on the cover and provide the fixation. At least one protuberant structure (5) is required to be present on the main body (4) of both the toilet lower cover and the toilet upper cover in order to provide the slow closure function.

Owing to the slow closure system according to the invention, the closing of the toilet covers in a sudden and uncontrolled manner is precluded. In said slow closure system, the lower cover may be connected with the main body (4) or the rotor (2), while it is also possible for the upper cover to be connected with the main body (4) or the rotor (2). by eliminating the need to cause demolition in the wall.
