[0001] This invention relates to the field of bathroom equipment, specifically to a quick-installation barrier-free chassis for water collection and drainage [IPC: A47K 3 / 40, A47K 3 / 00, A47K 3 / 17, A47K 3 / 405, E04F 15 / 02482, E03C 1 / 22; CPC: A47K 3 / 00, A47K 3 / 40, A47K 3 / 405].
[0002] A shower tray without a visible drainage device is known in the prior art [Patent No.: US 20090320204, Publication Date: 2009-12-31, Publication Type: A1]. This tray has circumferential sidewalls defining its perimeter, and multiple support wall sections, typically triangular in shape. One sidewall of each support wall section is positioned opposite the circumferential sidewall, forming a channel encircling the perimeter of the shower tray. Other pairs of sidewalls of the support wall sections are positioned opposite each other, forming drainage channels that connect the peripheral channel to a drain hole. The other sidewalls of the support wall sections have upper edges that form apexes of the shower tray near the central drain hole, and slope downwards and outwards from these apexes toward the peripheral channel. The drainage channels slope downwards and inwards from the peripheral channel toward the central drain hole. Therefore, water on the finished floor supported by the upper edges of the other pairs of sidewalls can flow outwards and downwards toward the peripheral channel under gravity, and then inwards and downwards toward the drain hole via the drainage channel.
[0003] The drawback of this analogy is that its installation process requires a significant amount of time and manpower.
[0004] Furthermore, a shower basin is known in the prior art [Patent No.: RU 2310364 C2, Publication Date: 2007.11.20]. This basin is made of stone, ceramic tile, or similar material and includes a supporting shell, a base, a bottom plate, a drain channel, and an edge frame. The edge frame and the bottom plate together form a gap for drainage in the drain channel area. This gap is formed by two parallel side surfaces extending at an angle relative to the vertical plane. The lower opening of the gap is laterally offset relative to its upper opening, and the offset is at least equal to the width of the upper opening. The bottom plate is designed to be detachable.
[0005] Another drawback of this analogy is that its installation process also requires a significant amount of time and manpower.
[0006] The closest in technical essence to this invention is a shower floor element [Patent No.: DE 102014218561A1, Publication Date: 2016-03-17]. This element includes a cover element providing a standing surface for the user, a drainage element, and a drain outlet; the difference is that the cover element can be removed without tools. A drainage element is installed on the drainage element.
[0007] The main technical problem with the prototype solution is that its manufacturing process is complex and its operation is difficult during on-site installation.
[0008] The objective of this invention is to eliminate the shortcomings of the prototype solution.
[0009] The technical advantages of this invention are: it enables quick and easy installation of the chassis within a ground recess, ensuring that the chassis surface is level with the ground, thereby creating an unobstructed environment between the ground and the chassis. Furthermore, this technology simplifies the manufacturing and maintenance processes of the chassis.
[0010] The above-mentioned technical effect is achieved through the following scheme: the drainage chassis is composed of a trough consisting of a base and side walls. The bottom of the trough is integrally cast with equally spaced cylindrical columns, and the columns are provided with longitudinal through holes with internal threads. At the same time, the upper end of the columns is connected to a support component, which consists of a cylindrical base and a rectangular top cover. The rectangular top cover of the support component is covered with a covering layer, and the bottom of the trough is equipped with a spiral support through the longitudinal through holes of the columns.
[0011] Specifically, the bottom surface of the tank has a slope extending towards the drain hole.
[0012] Specifically, a drain hole is provided at the lower part of the side wall of the tank, and a water seal device is provided in the drain hole.
[0013] Specifically, the spiral support is configured to be height-adjustable within the column via a rotational movement, which is achieved by the upper opening of the column acting on a groove.
[0014] Specifically, a protrusion is provided on the rectangular top cover of some of the support members, which can fix the cover layer and at the same time form a gap for drainage.
[0015] Specifically, the protrusion has the following shapes: a cross-shaped protrusion; a rectangular protrusion located in the center of the top cover of the support member; a rectangular protrusion provided along one side of the top cover of the support member; an L-shaped protrusion provided along two adjacent sides of the top cover of the support member; and a T-shaped protrusion located in the center of the top cover of the support member and provided along one side of its top cover.
[0016] Specifically, the protrusions on the top cover of the support are configured to accommodate multiple cover layers.
[0017] The present invention is illustrated with reference to the accompanying drawings. Attached Figure Description

[0042] A drainage system with a built-in collection and drainage platform enables the effective collection and management of surface runoff. Improperly designed drainage systems can lead to the accumulation of water in unintended areas, causing destructive effects. Built-in drainage systems face numerous challenges in application, including complex installation, the need for additional waterproofing, and difficulty in cleaning drain outlets. If the water supply and drainage system of such shower enclosures malfunctions, the pipes, buried under the paving layer, often cannot be directly accessed, necessitating complex structural repairs.
[0043] This study proposes a barrier-free built-in drainage and collection chassis, aiming to effectively solve various technical challenges faced by traditional built-in chassis in practical applications. The proposed chassis features a horizontally adjustable sealed structure, eliminating the need for on-site concrete pouring and ground sloping. The device eliminates the need for cover plates, water collection troughs, and water traps, thus ensuring the integrity of the pavement layer.
[0044] One of the key features of this device is its concealed design, meaning the drainage platform is not visually visible. The barrier-free, built-in drainage platform creates a flat, barrier-free structure, significantly improving accessibility and ease of entry into the shower area. When installed in a shower room, this built-in platform provides exceptional comfort and convenience for people with mobility impairments. The device is highly customizable in form and size, making it suitable not only for shower rooms but also for various other drainage applications, such as saunas, swimming pool walkways, and car washes.
[0045] The drainage and collection chassis consists of a water collection tank 1 and a spiral support column 2 at the bottom. The spiral support column 2 has external threads 18, a rectangular slot 19 machined at its top, and a support base 17 at its bottom. The spiral support column 2 is height-adjustable by rotating within a pin 8; the operator acts on the rectangular slot 19 through the opening at the top of the pin 8, thereby adjusting the height of the support column to ensure the drainage and collection chassis remains level even when the surface of the mounting position 21 is uneven. The water collection tank 1 consists of a base plate 3, side walls 4, and flanges 5. The bottom of the tank has a slope oriented towards the drain hole 6. The drain hole 6, with a water trap, is located at the bottom of the side wall 4. A connecting short pipe is provided around the drain hole 6 on the outside of the drainage and collection chassis for installing a water seal device and connecting to the drain pipe 7. The pin 8 is securely fixed to the base plate 3 and forms an integral structure with the tank. This fixed connection can be achieved through integral casting or welding. The pin 8 is cylindrical, and its interior has a cylindrical threaded through hole 18 along the axis of symmetry. Each pin 8 is topped with a support 9. The support 9 is an integral structure and can be configured with different models (including type 1, type 2, type 3, type 4, type 5, and type 6) according to requirements.
[0046] Type 1: The support 9 consists of a cylindrical base 10 and a flat rectangular cover plate 11 on top.
[0047] Type 2: The support member 9 consists of a cylindrical base 10 and a rectangular cover plate 11 on top, which has a cross-shaped protrusion 12.
[0048] Type 3: The support member 9 consists of a cylindrical base 10 and a rectangular cover plate 11 on top, with a rectangular protrusion 13 at the center of the top of the cover plate.
[0049] Type 4: The support member 9 consists of a cylindrical base 10 and a rectangular cover plate 11 on top, with a rectangular protrusion 14 on one side of its upper surface.
[0050] Type 5: The support member 9 consists of a cylindrical base 10 and a rectangular cover plate 11 on top, with L-shaped protrusions 15 on its upper surface along two adjacent sides.
[0051] Type 6: The support member 9 consists of a cylindrical base 10 and a rectangular cover plate 11 on top, which has a T-shaped protrusion 16 in the middle and along one of its edges.
[0052] The various designs of the support member 9 are intended to create diverse geometric layouts to accommodate almost all sizes and shapes of paving layers 20. The upper surface of the rectangular cover plate 11 of the support member 9 is flush with the top of the flange 5 on the horizontal plane.
[0053] The paving layer 20 is placed on the support member 9 and is flexibly positioned by the raised structure on the top of the rectangular cover plate 11. The gaps formed between the paving layers 20 ensure a high standard of flow capacity. The non-fixed limiting design of the paving layer 20 is designed to ensure accessibility to the drainage system and meet the functional requirement 20 of quickly replacing the cover element when necessary.
[0054] Because the drainage chassis device is composed of a tank with an integrated base plate and side walls, and cylindrical pins with internally threaded longitudinal holes are cast at equal intervals on the base plate, the upper end of the pins is connected to a support component consisting of a cylindrical base and a rectangular cover plate, and a cover plate is installed on the rectangular cover plate. At the bottom of the tank, the lower end of the pins is fitted with a spiral support column through the longitudinal hole. This structure ultimately achieves unobstructed horizontal connection between the plane above the drainage area and the plane of the adjacent area.
[0055] Thanks to the slope at the bottom of the trough towards the drainage holes, water can be discharged naturally, thus eliminating the need for sloping treatment on the surface of the pavement.
[0056] By installing drainage holes with water traps at the bottom of the side wall, smooth water drainage is ensured.
[0057] The spiral support column can be height adjusted by rotating inside the pin (driving the rectangular groove via the pin top hole), thereby accurately calibrating the level of the groove and ensuring that the surface formed is in an ideal state.
[0058] Because the rectangular support cover has rectangular protrusions, these protrusions fix the cover layer and form drainage joints, ensuring that an unobstructed horizontal plane is formed between the drainage area and the adjacent ground, while also allowing water to drain freely through the gaps formed between the paving layers.
[0059] Thanks to the diverse selection of support protrusion structures, including cross-shaped, centered rectangle, single-sided rectangle, double adjacent-sided L-shaped, and top-center combined with a single-sided T-shaped protrusion, this design can achieve a stable layout of the paving layer above the drainage area without the need for a frame.
[0060] Thanks to the various types of support components, they can be flexibly combined according to the various geometric textures of the covering layer, thereby achieving a stable arrangement of the paving layer above the drainage area without the need for frame constraints.
[0061] Thanks to the non-tightly positioning of the paving layer, this barrier-free quick-assembly drainage chassis system can be assembled and deployed efficiently.
[0062] The non-fixed nature of the cover element ensures the accessibility of the drainage system, allowing for routine maintenance without complex disassembly procedures or high repair costs.
[0063] The ease of installation and removal of the paving layer allows for rapid replacement, enabling flexible changes in environmental design.
[0064] This barrier-free, quick-assembly drainage chassis is suitable for any location requiring efficient collection and management of surface runoff. The following is a demonstration of an application scheme for the barrier-free, quick-assembly drainage chassis system.
[0065] 1. The user is placed on the surface of the paving layer 20 above the drainage area (tank 1) to prepare for bathing.
[0066] 2. Follow the bathing procedure.
[0067] 3. After the bathing process is completed, the user moves out of the paving layer 20 above the drainage area (tank 1).
[0068] The installation process for the barrier-free quick-installation drainage chassis system is as follows: Install the tank 1 at the designated location for water collection and drainage. The tank consists of a base plate 3, side walls 4, and flanges 5, and includes a pin 8 and a spiral support column 2. Connect the drain hole 6 with a water seal to the connector for installing a dry water seal, and connect it to the drain pipe 7. By using a screwdriver through the upper hole of the pin 8 and applying it to the slot 19, the spiral support column 2 is rotated inside the pin 8 to adjust the height, thereby adjusting the shower drain base to a horizontal plane, unaffected by the flatness of the ground. Fix the support member 9 to each pin, selecting a suitable type of support member, and lay the surface layer between the rectangular protrusions, then lay the surface layer on top of the support member 9. Example 1
[0069] A quick-installation drainage chassis system with barrier-free space is realized within the pre-prepared shower enclosure niche 21.
[0070] All components of the chassis were manufactured using a CreatBot D1000 3D printer and are made of ABS plastic.
[0071] The recess 21 is designed to be 10 cm deep, and a rectangular groove 1 is housed inside. The depth of the groove at its highest extreme point is 2 cm, and the depth at its lowest extreme point is 5 cm. The groove is supported by a spiral support column 2 with a height of 9 cm. By using a screwdriver to drive the rectangular groove 19 through the top hole of the pin 8, the spiral support column 2 is rotated inside the pin, thereby precisely calibrating the horizontal reference plane of the drainage base. The water collection groove 1 is composed of a base plate 3, side walls 4, and flanges 5. The pin 8 and the base plate 3 are integrally molded. The bottom of the groove has a slope that is oriented towards the drain hole 6. The drain hole 6 with a water trap is connected to the dry stop valve interface and the drain pipe 7. Support members 9 are fixed on the top of each pin 8, and a specific model is selected according to the paving requirements to ensure that the paving layer 20 can be accurately embedded between the rectangular protrusions. The paving layer 20 is placed on top of the support members 9 and accurately embedded between the protruding structures on the top of the rectangular cover plate 11. The paving layer 20 is placed on top of the support member 9, and non-fastening restraint is achieved through the protruding structure on the top of the support member. The gaps formed between the paving layers 20 ensure extremely high flow efficiency. Example 2
[0072] Within the recessed niche 21 pre-designed in the car wash area, a quick-installation drainage chassis system with unobstructed space is implemented. The niche 21 is designed to be 20 cm deep. An irregularly shaped trough 1 is housed within it, its spatial layout designed to meet the drainage needs during vehicle washing operations. The trough 1 has a depth of 15 cm at its highest extreme point and 18 cm at its lowest extreme point, supported by a 10 cm high spiral support column 2. A screwdriver is used to adjust the height of the threaded support column 2 by rotating it within the rectangular slot 19 through the upper hole of the pin 8, ensuring the car wash trough maintains the correct flatness in the horizontal direction. The water collection trough 1 consists of a base plate 3, side walls 4, and flanges 5. The bottom of the trough has a slope oriented towards the drain hole 6. The drain hole 6, equipped with a water trap, connects to a dry check valve interface and a drain pipe 7. Support members 9 are installed on top of each pin 8, and a specific model is selected according to design requirements to ensure that the pavement layer 20 can be precisely embedded between the rectangular protrusions. The pavement layer 20 is placed above the support members 9, i.e., between the top protrusions of the rectangular cover plate 11. The pavement layer 20 is positioned above the support members 9 and is loosely secured by the protrusions on the upper part of the support members 9. Highly drainable gaps are formed between the components of the pavement layer 20.
[0073] All components of the drainage chassis were manufactured using a CreatBot D1000 3D printer and are made of ABS plastic. Example 3
[0074] A quick-installation drainage chassis system with barrier-free space is realized within a recessed niche 21 pre-designed in the swimming pool walkway. The niche 21 is designed to be 20 cm deep. A rectangular trough 1 is housed within it, its shape conforming to the contours of the swimming pool walkway. The high extreme point depth of the trough 1 is 8 cm, and the low extreme point depth is 15 cm, supported by a spiral support column 2 with an initial height of 15 cm. Using a screwdriver to drive the rectangular slot 19 through the pin's top hole, the height of the threaded support column 2 is adjusted by rotating it within the pin 8, thereby precisely calibrating the horizontal reference plane of the swimming pool walkway drainage chassis. The water collection trough 1 consists of a base plate 3, side walls 4, and flanges 5. The pin 8 is securely fixed to the base plate 3, forming an integral structure with the trough. This fixed connection is achieved using an integral casting process. The bottom of the trough has a slope oriented towards the drain hole 6. The drain hole 6, with a water trap, is connected to a dry stop valve interface and a drain pipe 7. Support members 9 are fixed to the top of each pin 8, and a specific model is selected according to the paving requirements to ensure that the paving layer 20 can be precisely embedded between the rectangular protrusions. The paving layer 20 is placed above the support members 9, between the top protrusions of the rectangular cover plate 11. The paving layer 20 is placed above the support members 9 and loosely fixed by the protrusions on the top of the support members 9. The gaps formed between the paving layers 20 ensure extremely high flow efficiency.
[0075] The assembly time of the drainage chassis in "Example 1", "Example 2" and "Example 3" was measured and compared with similar products. During the deployment of the drainage chassis in "Example 1", "Example 2" and "Example 3", the assembly and installation time of the system was 2 hours.
[0076] In contrast, the assembly and installation of a similar "shower chassis without visible drainage device" [Patent No.: US 20090320204 Publication Date: 2009-12-31, A1] takes up to 8 hours.
[0077] When implementing another similar product, “shower basin support housing” [Patent No.: RU 2310364 C2, Publication Date: 2007.11.20], its assembly and installation took 6 hours.
[0078] When implementing the similar "shower room floor element" [Patent No.: DE 102014218561 A1, Publication Date: 2016-03-17], its assembly and installation took up to 5 hours.
[0079] Experimental studies on the time required for assembling and installing sanitary fixtures show that the quick-installation barrier-free drainage chassis proposed in this invention is significantly superior to existing similar technologies in terms of installation efficiency, and its required assembly and deployment time is greatly reduced compared to similar products.
[0080] During the implementation of "Example 1", "Example 2", and "Example 3", a laser level was used to precisely measure the horizontal slope between the plane above the drainage area and the adjacent ground, and the measurement was compared and analyzed with similar technical solutions. The laser level showed that the drainage systems in "Example 1", "Example 2", and "Example 3" all exhibited a precise horizontal plane.
[0081] According to laser level testing, when implementing a similar "shower chassis without visible drainage device" [Patent No.: US20090320204, Publication Date: 2009-12-31, A1], its horizontal plane exhibits a slope deviation of 25 degrees.
[0082] When implementing another similar "shower basin support housing" [Patent No.: RU 2310364 C2, Publication Date: 2007.11.20], its surface is tilted at an angle of 18 degrees relative to the horizontal plane.
[0083] When implementing the similar "shower room floor element" [Patent No.: DE 102014218561 A1, Publication Date: 2016-03-17], its surface is tilted at a 15-degree angle relative to the horizontal plane.
[0084] Experimental results show that the quick-installation barrier-free drainage chassis proposed in this invention achieves zero-slope connection between the plane above the drainage area and the adjacent ground, while the comparable objects all have obvious horizontal deviations.
[0085] In summary, this invention enables the rapid and convenient installation of the drainage chassis in a ground niche, and creates a completely flat and unobstructed horizontal surface between the plane above the drainage area and the adjacent ground.
