Description

[0001] A Fitting Used in Drainage Systems

[0002] Technical Field

[0003] The invention relates to water drains used in wet areas such as kitchens, bathrooms, toilets, terraces, balconies, and gardens, which facilitate the discharge of water into the sewage system.

[0004] Prior Art

[0005] In the existing technique, connection pieces are used to connect water drains to pipes of varying diameters. The connection piece is fixed to the drain pipe using an adhesive method.

[0006] To complete the installation, particularly in countries like the United States and Canada, leakage tests are required. The apparatuses used for leakage tests are typically different from the pipes in the building's plumbing system. Therefore, connection pieces are used during the testing phase. These connection pieces enable the positioning of the test apparatuses within the plumbing system. The connection pieces used in this process are secured to the system by applying adhesive chemicals.

[0007] In the existing technique, ceramic materials are generally used on surfaces where water drains are installed. The adhesive fixation of the connection piece is typically performed after the ceramic tiling is completed. However, ceramic tiling professionals often avoid performing the fixation process due to time constraints and cost concerns.

[0008] After the ceramic tiling process is completed, a plumber must be called again to install the connection piece. Performing this secondary operation by the plumber results in both time and cost inefficiencies.

[0009] The American patent document with the code US2008229494A1 in the existing technique mentions a shower drainage adapter. This adapter ensures the connection between the main plumbing pipe and the point drain of the shower. In the described connection process, adhesive is used to secure both the upper and lower parts. However, the document does not disclose a connection piece with flexible steps.

[0010] In the existing technique, the connection piece is secured to the main plumbing pipe by applying adhesive around its outer surface. This fixation process is time-consuming and incurs additional financial costs. Moreover, the adhesive's strength diminishes over time, especially due to the chemicals used during cleaning. Consequently, the connection piece loosens, leading to water leaks.

[0011] The Purpose of the Invention

[0012] The purpose of the invention is to provide a water drain where two components are joined together without the use of chemical adhesives.

[0013] Another purpose of the invention is to provide a water drain that allows the internal connection of two components in water drainage systems requiring extensions.

[0014] A further purpose of the invention is to provide a water drain that enables the internal connection of water drainage pipes of different diameters.

[0015] An additional purpose of the invention is to provide a water drain where two components are internally joined without any water or odor leakage. The water drain developed to achieve the stated objectives is characterized by:

[0016] A connection piece (50, 112) made of a plastic-derived material with a flexible structure, featuring a step (54, 112.1.1) to enable the joining of the reservoir (60) or body (111) with the drain pipe (30, 114) without the use of adhesives or chemicals; and A water channel (53, 112.2.4) that facilitates the transfer of water from the reservoir (60) or body (111) to the drain pipe (30, 114).

[0090] Detailed Description

[0091] The invention relates to water drains used in wet areas such as kitchens, bathrooms, toilets, terraces, balconies, and gardens to channel wastewater into the sewage system. The subject water drain comprises a panel (10), pan (20), drain pipe (30), intermediate piece (40), connection piece (50), reservoir (60), movable flange (70), cover (80), height adjustment piece (90), and a point water drain (100). Additionally, in alternative implementations of the invention, connection pieces (112) are also utilized in side outlet siphons (110).

[0092] The water drain subject to this invention is primarily used in buildings with suspended ceilings and / or structures made of wood. The portion of the water drain facing the floor is surrounded by a panel (10). The panel (10) is a building material produced by combining wood strands with adhesive and pressing them together. This material provides a durable flooring layer.

[0093] A pan (20) is placed on the upper surface of the panel (10). The pan (20) ensures both sound and water insulation and provides a sloped upper surface. The sloped surface directs water directly to the drain, preventing water accumulation.

[0094] The pan (20) consists of two symmetrical parts. These two parts are connected to each other through a male connection (21) and a female connection (22). The male connection (21) and the female connections (22) have an angle "a," enabling them to interlock mechanically by fitting into each other. Each pan (20) includes a reservoir slot (23). The reservoir (60) is positioned within the reservoir slot (23). This configuration ensures that the reservoir (60) is stably placed on the pan (20). In other words, the reservoir (60) can be positioned on the pan (20) without requiring precise adjustments.

[0095] The reservoir (60) in the water drain subject to this invention is placed on the intermediate piece (40). The reservoir (60) and the intermediate piece (40) are connected via a connection piece (50). In an alternative implementation of the invention, the intermediate piece (40) may be optionally omitted. When the intermediate piece (40) is not used, the connection piece (50) directly links the reservoir (60) to the drain pipe (30).

[0096] The connection piece (50) consists of two parts: a rigid part (50.1) and a flexible part (50.2). The rigid part (50.1) includes recesses (50.1.1) and projections (50.1.2), while the flexible part (50.2) also features recesses (50.2.1) and projections (50.2.2).

[0097] The projection (50.1.2) on the rigid part (50.1) fits into the recess (50.2.2) on the flexible part (50.2). Similarly, the projection (50.2.1) on the flexible part (50.2) fits into the recess (50.1.1) on the rigid part (50.1). This design allows the two parts to be mechanically fixed to each other.

[0098] The connection piece (50) consists of two sections: an upper section (51) and a lower section (52). The upper section (51) is wider than the lower section (52). This difference in diameter between the upper section (51) and the lower section (52) allows for compatibility between the reservoir (60) and the intermediate piece (40) or the drain pipe (30). In alternative implementations of the invention, where there is no diameter difference between the reservoir (60) and the intermediate piece (40) or the drain pipe (30), the upper section (51) and the lower section (52) have the same diameter.

[0099] The connection piece (50) features steps (54). These steps (54) are made of plastic-derived material and have a flexible structure. The flexible steps (54) prevent potential leaks. Additionally, their flexibility enables the connection piece (50) to be pressed into the intermediate piece (40), reservoir

[0100] (60), or drain pipe (30), ensuring a secure fit.

[0101] The upper section (51) of the connection piece (50) is placed within the water channel (62) of the reservoir (60), while the lower section (52) is positioned in the water channel (41) of the intermediate piece (40) or the water channel (31) of the drain pipe (30). The connection piece (50) ensures that water from the reservoir (60) is transferred to the intermediate piece (40) or drain pipe (30) without any leakage.

[0102] The intermediate piece (40) provides the connection between the connection piece (50) and the drain pipe (30). Additionally, the intermediate piece (40) collects any potential leaks from the mortar holes

[0103] (61) in the reservoir (60) and directs them toward the drain pipe (30).

[0104] The reservoir (60) in the water drain subject to this invention collects water from the point drain (100) and channels it toward the drain pipe (30). The reservoir (60) includes mortar holes (61), into which the mortar placed on the floor enters. This ensures that the reservoir (60) is securely and stably positioned on the floor.

[0105] The reservoir (60) contains a movable flange (70). Once the movable flange (70) is positioned on the reservoir (60), it allows the point water drain (100) to rotate 360 degrees. This rotational capability ensures the point water drain (100) can be secured without requiring precise adjustments. After the movable flange (70) is positioned appropriately, it is fixed to the reservoir (60) via fixing holes (71). The fixation process can be carried out using screws and / or adhesive methods.

[0106] Adhesives are typically used to bond materials of the same type. In water drainage systems, materials such as PVC (Polyvinyl Chloride), PP (Polypropylene), and SBS (Styrene-Butadiene-Styrene) are commonly used. For the reservoir (60) and the drain pipe (30) to adhere properly, they must be made of the same material. This requirement creates challenges during application. The connection piece (50) in this invention eliminates the need for adhesives by enabling the reservoir (60) and the drain pipe (30) to be connected without bonding materials. Consequently, the necessity of using water drain components made of identical materials is removed. The connection piece (50) provides ease of use and application.

[0107] The movable flange (70) includes a cover (80). This cover (80) prevents unwanted materials, such as debris, from entering the water drain during construction or renovation. After construction is completed, the tearable section (81) on the cover (80) can be easily removed by pulling on the handle (82).

[0108] Height adjustment pieces (90) are positioned on the cover (80). These pieces (90) allow for the height of the point water drain (100) to be adjusted relative to the floor. Depending on the need, any number of height adjustment pieces (90) can be used. This feature ensures the point water drain (100) can be easily used in applications where the floor level is raised or the drain cavity is lower.

[0109] The point water drain (100) is the part of the system where surface water on the floor connects to the drainage system. The point water drain (100) may include a strainer or grate.

[0110] The water drainage system described in this invention can also be used with side outlet siphons (110) in addition to point water drains (100). The side outlet siphons (110) consist of a body (111), a connection piece (112), an intermediate piece (113), and a drain pipe (114).

[0111] In the side outlet siphon (110) system, the body (111) is the component that houses the s-trap system, which prevents unwanted elements such as foul odors and pests from entering the plumbing system.

[0112] The connection between the body (111) and the intermediate piece (113) is established through the connection piece (112). The connection piece (112) consists of two parts: a flexible part (112.1) and a rigid part (112.2). The flexible part (112.1) and the rigid part (112.2) are bonded together using adhesive and / or heat. After this bonding process, the connection piece (50, 112) becomes a unified, standalone component for use.

[0113] The flexible layer (112.1) includes steps (112.1.1) and projections (112.1.2). The steps (112.1.1) are made of plastic-derived material and have a flexible structure. These flexible steps (112.1.1) prevent potential water leaks and the spread of foul odors from the body (111) and intermediate piece (113) to the external environment. Additionally, the flexibility of the steps (112.1.1) allows the connection piece (112) to be pressed into both the intermediate piece (113) and the body (111), ensuring a secure fit.

[0114] The rigid part (112.2) includes a boundary projection (112.2.1), fixing channel (112.2.2), sealing projection (112.2.3), and water channel (112.2.4). The boundary projection (112.2.1) defines the limits between the drain pipe (114) and the connection piece (112).

[0115] The fixing channel (112.2.2) has a smaller diameter than the surface diameter of the connection piece (112). This fixing channel (112.2.2) mechanically secures the flexible part (112.1) and the rigid part (112.2) together. In this configuration, the projection (112.1.2) on the flexible part (112.1) fits into the fixing channel (112.2.2). In alternative implementations of the invention, the fixing channel (112.2.2) may be omitted.

[0116] The sealing projection (112.2.3) is “t” wider than the diameter of the connection piece (112). This sealing projection (112.2.3) prevents water leaks between the connection piece (112) and the body (H l).

[0117] The connection piece (112) links the drain pipe (114) to the intermediate piece (113). The intermediate piece (113) is used for plumbing connections that require extended lengths. Its length can be adjusted as needed. The inner section of the intermediate piece (113) includes a boundary projection (113.1).

[0118] In alternative implementations of the invention, a connector (120) can be positioned on the connection pieces (50). The compatibility piece (120) enables the use of the connection piece (50) with water drains of different diameters. The connector (120) consists of an outer part (121) and a gasket (122). The gasket (122) includes a sealing projection (122.1). This sealing projection (122.1) prevents potential leaks during the connection process.

[0119] The connection piece (50) in this invention enables the reservoir (60) or the body (111) to be connected to the drain pipe (30, 114) internally without the use of adhesives or chemicals. This connection is established between the inner section of the drain pipe (30, 114) and the inner section of the reservoir (60) or the body (111).

[0120] In an alternative implementation of the invention, the connection piece (50) can connect the inner section of the drain pipe (30, 114) to the outer section of the reservoir (60) or the body (111). Additionally, connections can be made externally, outer-to-outer. However, the preferred implementation of the invention features an inner-to-inner connection.

[0121] The water drain developed to achieve the stated objectives is characterized by:

[0122] A connection piece (50, 112) made of a plastic-derived material with a flexible structure, featuring a step (54, 112.1.1) to enable the joining of the reservoir (60) or body (111) with the drain pipe (30, 114) without the use of adhesives or chemicals; and

[0123] A water channel (53, 112.2.4) that facilitates the transfer of water from the reservoir (60) or body (111) to the drain pipe (30, 114).
