Patent Application
20210189711
The present application relates generally to the field of bath and shower drain installation assemblies.
When a person is installing a bathtub, that person may need access to the underside of the bathtub in order to install the drain to/in the drain opening of the bathtub. Once installed, the drain my project from the underside of the bathtub. The bathtub then would be lifted up, the drain opening lined up with a drain pipe in the floor, and then slid onto or over the drain pipe. This installation process can be difficult for a single person to do on their own. And if the bathtub is heavy, such as for an iron stand-alone bathtub, more than two people may be required to lift the bathtub.
Accordingly, it may be desirable to use a drain that can be installed entirely from the top-side of the bathtub (e.g., without requiring access to the underside of the bathtub.)
At least one embodiment relates to a drain installation assembly. The drain installation assembly includes a drain body and a drain coupling. The drain coupling is configured to be inserted into a drain opening of a wash basin from a top side of the wash basin. The drain coupling comprises a first coupling end and a second coupling end, the second coupling end positioned opposite to the first coupling end. The drain coupling further includes a squeeze portion positioned between the first coupling end and the second coupling end, the squeeze portion formed of a flexible material. The drain body comprises a body flange extending radially away from the drain body. The squeeze portion is configured to deform so as to define a squeeze bulge when the drain coupling is coupled to the drain body, the squeeze bulge having a diameter greater than a diameter of the drain opening of the wash basin.
At least one embodiment relates to a drain assembly for coupling a wash basin to a drain pipe from above the wash basin. The drain assembly includes a drain coupling and a drain body configured for coupling to the drain coupling. The drain coupling is configured to be inserted into a drain opening of the wash basin from a top side of the wash basin. The drain coupling is also configured to extend into the drain pipe.
At least one embodiment relates to a method of installing a drain assembly in a wash basin. The method incudes inserting a drain coupling into a drain opening in the wash basin from a top side of the wash basin, and inserting a drain body into the drain coupling, and coupling the drain body to the drain coupling.
Referring generally to the FIGURES, a blind drain installation assembly is shown according to various exemplary embodiments. The blind drain installation assembly is structured to couple a drain opening in a wash basin to a drain pipe in a floor without requiring access to the underside of the wash basin. This may allow an installer of the wash basin to install the blind drain installation assembly without having to lift the wash basin off the floor. Instead, the installer may slide the wash basin over the drain pipe in the floor and line up the drain pipe with the drain opening in the wash basin. Doing so may save time and avoid injury.
Referring to
Disposed between the top basin surface 110 and the bottom basin surface 120, proximate the drain opening 130, may be a cavity (e.g., channel, aperture, etc.), shown as an overflow channel 140.
Referring to
Disposed beneath the wash basin 100 is a drain pipe (e.g., drain plumbing, drain tube, pipe, conduit, etc.) 240 including a top drain pipe portion 245. The top drain pipe portion 245 may be configured to extend through the floor opening 107 such that the top drain pipe portion 245 is disposed above the floor 105. In some embodiments, the top drain pipe portion 245 is even (e.g., flush) with the floor 105 and does not extend above the floor 105. This may be desirable during the installation of the wash basin 100. The wash basin 100 may be heavy—so heavy that lifting the wash basin 100 may be difficult or dangerous. With the drain pipe 240 flush with the floor 105, the wash basin 100 may be slid over the floor opening 107 to line up the drain opening 130 with (e.g., make the drain opening 130 concentric about) the drain pipe 240. The drain coupling 230 is configured to slide through the drain opening 130 and surround the drain pipe 240. The drain coupling 230 and the drain pipe 240 cooperate to prevent a flow of water from flowing between the drain pipe 240 and the drain coupling 230. In some embodiments, the drain pipe 240 and the drain coupling 230 are coupled using a retention ring or compression ring. In other embodiments, the drain coupling 230 forms a water-tight friction fit with the drain pipe 240. In some embodiments, the elasticity of the material used to form the drain coupling 230 creates a watertight seal between the drain coupling 230 and the drain pipe 240.
Turning to
The first inner surface 310 is configured to interface with the drain pipe 240 and provide a sealant such that a watertight seal is formed between the drain coupling 230 and the drain pipe 240. The drain coupling 230 may include a plurality of annular projections 313 extending laterally away from the first inner surface 310 and toward the central axis Z. As shown in
Proximate the first lower end 306, the first inner surface 310 has a second diameter D2. The first inner surface 310 maintains a circular cross-section of the second diameter D2 extending from the first lower end 306 to the first upper end 304. In some embodiments, the diameter of the first inner surface 310 proximate the first upper end 304 is different (e.g., greater, lesser, etc.) than the second diameter D2. The first inner surface 310 is configured to accept the drain body 220. The first inner surface 310 is also configured to allow a flow of water to pass through.
A generally annular first flange 314 extends laterally outwardly from (e.g., orthogonally to) the first outer surface 308. As shown in
The first flange 314 includes a first flange first surface 316, a first flange second surface 318, and a first flange third surface 320. The first flange first surface 316 is disposed at an underside of the first flange 314 and is configured to cooperate and interface with the top basin surface 110 such that a water-tight seal is created between the first flange 314 and the top basin surface 110. The first flange first surface 316 extends laterally outwardly from and is generally perpendicular to and contiguous with the first outer surface 308. In some embodiments, the first flange first surface 316 projects outwardly from the first outer surface 308 at an angle that is not perpendicular. The first flange second surface 318 is contiguous with the first flange first surface 316. The first flange second surface 318 may be concentric about the center axis Z and may have the fourth diameter D4. The first flange second surface 318 may be parallel with the first outer surface 308. The first flange third surface 320 is disposed on a top side of the first flange 314. The first flange third surface 320 is contiguous with the first flange second surface 318 and may be parallel to the first flange first surface 316. The first flange third surface 320 is configured to interface with a portion of the drain body 220 to create a watertight seal between the drain coupling 230 and the drain body 220. The first flange third surface 320 is contiguous with the first inner surface 310. The first flange third surface 320 and the first inner surface 310 may meet at a corner. In some embodiments, the corner is chamfered (e.g., filleted, rounded, blunted, etc.) such that the transition between the first flange third surface 320 and the first inner surface 310 is uninterrupted (e.g., smooth, rounded, etc.).
The drain coupling 230 further includes a generally annular flange shown as coupling threads 330. The coupling threads 330 interrupt the first inner surface 310 such that a portion of the first inner surface 310 exists between the first upper end 304 and the coupling threads 330. As shown in
The drain coupling 230 may further include a plurality of holes (e.g., orifices, openings, etc.) shown as coupling holes 340. The coupling holes 340 extend through the first inner surface 310 and the first outer surface 308 such that the drain coupling 230 is in fluid communication with the overflow channel 140 when the drain coupling 230 is inserted into the drain opening 130. In some embodiments, the drain coupling 230 does not include the coupling holes 340. For example, coupling holes 340 may not be advantageous for use in an alternative wash basin 100 that does not include the overflow channel 140 or a similar overflow channel. Each one of the coupling holes 340 is defined by an annular coupling hole surface 342 that is contiguous with both the first inner surface 310 and the first outer surface 308.
Turning to
The drain body 220 further includes a generally annular second flange 414 extending laterally outwardly from (e.g., orthogonal to) the second outer surface 408. As shown in
The second flange 414 includes a second flange first surface 416, a second flange second surface 418, and a second flange third surface 420. The second flange first surface 416 is contiguous with and concentric about the second outer surface 408. In some embodiments, the second flange first surface 416 is perpendicular to the second outer surface 408. In other embodiments, the second flange first surface 416 meets the second outer surface 408 at an angle other than perpendicular. In some embodiments, where the second outer surface 408 and the second flange first surface 416 meet is rounded (e.g., not a sharp corner). This rounded interface between the second outer surface 408 and the second flange first surface 416 may assist in biasing the first flange 314 toward the surfaces defining the drain opening 130 to create a watertight seal between the top basin surface 110, the first flange 314, and the second flange 414.
The second flange first surface 416 is contiguous with the second flange second surface 418. The second flange second surface 418 may be concentric about the central axis Z. The second flange second surface 418 is contiguous with the second flange third surface 420. The second flange third surface 420 may meet the second flange first surface 416 at a corner such that there is no second flange second surface 418. In some embodiments, the second flange second surface 418 is chamfered such that the transition between the second flange first surface 416 and the second flange third surface 420 is smooth (e.g., rounded, uninterrupted, etc.). The second flange third surface 420 is also contiguous with the second inner surface 410. The second flange third surface 420 may be perpendicular to and concentric about the second inner surface 410. In some embodiments, where the second flange third surface 420 and the second inner surface 410 meet may be chamfered such that the transition from the second flange third surface 420 to the second inner surface 410 is uninterrupted by a sharp corner or similar discontinuity (e.g., smooth, rounded, continuous, etc.).
The drain body 220 further includes a generally annular, threaded body, shown as drain body threads 430. The drain body threads 430 interrupt the second outer surface 408 such that a portion of the second outer surface 408 exists between the second upper end 404 and the drain body threads 430. In some embodiments, the drain body threads 430 are disposed proximate the second lower end 406 such that the second outer surface 408 does not exist between the drain body threads 430 and the second lower end 406. In some embodiments, the drain body threads 430 extend between the second upper end 404 and the second lower end 406 such that the second outer surface 408 is entirely covered by the drain body threads 430. As shown in
The drain body 220 may further include overflow openings 440. The overflow openings interrupt both the second outer surface 408 and the second inner surface 410. The overflow openings 440 may extend through the second outer surface 408 and the second inner surface 410 such that a flow of water may exit the drain body 220 through the overflow openings 440. Each of the overflow openings 440 is defined by a generally rectangular surface, shown as an overflow opening surface 442, contiguous with both the second outer surface 408 and the second inner surface 410.
The drain body 220 further includes a generally annular flange, shown as a second lattice 450, disposed within the second inner surface 410 and extending laterally away from the second inner surface 410, toward the central axis Z. As shown in
The second lattice 450 includes a generally planar top second lattice surface 452 and a generally planar bottom second lattice surface 454. The top second lattice surface 452 and the bottom second lattice surface 454 are both contiguous with the second inner surface 410.
Extending through both the top second lattice surface 452 and the bottom second lattice surface 454 may be a plurality of openings configured to allow a flow of water to pass through the drain body 220, and likewise the drain coupling 230. As shown in
The plurality of support structures 456 are configured to cooperate proximate the central axis Z to support a generally annular coupling body 460. The coupling body 460 is concentric about the central axis Z. The coupling body 460 includes a coupling body orifice 465 concentric about the central axis Z and configured to accept a fastener, such as may be included in a drain stopper or the toe tap 210. In some embodiments, the coupling body orifice 465 interfaces with the toe tap 210 such that the toe tap 210 may be removably coupled to the drain body 220. In some embodiments, the coupling body orifice 465 is not required during the installation of the toe tap 210, but gives an installer of the blind drain installation assembly 200 options as to which type of stopper or toe tap 210 they may prefer to use.
During installation of the drain body 220 and the drain coupling 230, the coupling threads 330 and the drain body threads 430 are threaded together. This may require an amount of torque greater than can be applied without a tool. The second lattice 450 is configured to interface with a tool (e.g., tub drain wrench, etc.) such that a torque may be applied through the second lattice 450 and to the drain body 220, assisting in threading together the drain coupling 230 and the drain body 220. More specifically, the tool may be configured to interface with the support structures 456 such that rotation of the tool results in the rotation of the drain body 220. The second lattice 450 is configured to withstand high torque loads without failure (e.g., separating from the drain body 220, cracking, bending, deforming, etc.).
Generally speaking, the tool is configured to turn the drain body 220 and tighten the drain body threads 430 to the coupling threads 330 such that coupling threads 330 traverse up the drain body threads 430, toward the bottom basin surface 120. This movement is made possible by the material properties of the drain coupling 230.
Referring to
At 604, the wash basin 100 is positioned such that the drain opening 130 is centered over (e.g., concentric about) the drain pipe 240.
At 606, the drain coupling 230 is inserted through the drain opening 130 and around the top drain pipe portion 245 such that the first flange first surface 316 interfaces with the top basin surface 110. In some embodiments, the plurality of annular projections 313 also interface with the drain pipe 240, further aiding in creating a watertight seal. In some embodiments, the watertight seal is a consequence of the compliant (e.g., elastomeric) material used to manufacture the drain coupling 230. The drain coupling 230 is compliant such that the first inner surface 310 may receive a non-cylindrical drain pipe 240. In some embodiments, the drain pipe 240 has an elliptical, hexagonal, octagonal, or otherwise non-circular cross-section. However, due to the compliance of the drain coupling 230, a watertight seal may still be formed between the first inner surface 310 and the drain pipe 240. In some embodiments, it may be desirable to insert the drain coupling 230 within the drain pipe 240.
In some embodiments, where the top drain pipe portion 245 is below the floor 105, it may be the case that the coupling threads 330 are also disposed below the floor 105 during installation. When the drain coupling 230 is first disposed within the drain opening 130, the coupling threads 330 are located below the bottom basin surface 120 and above the top drain pipe portion 245. A portion of the drain coupling 230 is disposed between the coupling threads 330 and the bottom basin surface 120, shown as a compliant portion (e.g., rubber portion, rubber coupling portion, elastomeric portion, etc.) 504.
At 608, the drain body 220 is inserted into the drain coupling 230 such that the drain body threads 430 are resting on the coupling threads 330.
At 610, the drain body 220 is theadingly coupled to the drain coupling 230. In some embodiments, a tool is used to threadingly couple the drain body 220 to the drain coupling 230. When the drain body 220 and the drain coupling 230 are fully seated (e.g., the coupling threads 330 and the drain body threads 430 are tightened to a desired torque), the second flange first surface 416 interfaces with the first flange third surface 320 such that the first flange 314 is squeezed between the second flange 414 and the top basin surface 110, acting as a rubber washer. The squeezing of the first flange 314 creates a watertight seal between the second flange 414 and the top basin surface 110.
When the drain body threads 430 are threaded to the coupling threads 330, the coupling threads 330 translate up, in a direction generally toward the bottom basin surface 120 along the central axis Z. Further, the first lower end 306 slides up the drain pipe 240 toward the bottom basin surface 120 without jeopardizing the watertight seal between the drain coupling 230 and the drain pipe 240. Meanwhile, the first flange 314 does not change position relative to the top basin surface 110. The translational movement of the coupling threads 330 toward the bottom basin surface 120 is allowed because of the compliance of the material used to manufacture the drain coupling 230. The coupling threads 330 squeeze the compliant portion 504 between the coupling threads 330 and the bottom basin surface 120, creating a squeeze bulge 508. The squeeze bulge 508 is configured to interface with the bottom basin surface 120 to secure the drain coupling 230 to the wash basin 100. The squeeze bulge 508 has a squeeze diameter DSQ that is wider than both the drain opening diameter D1 and the third diameter D3. The squeeze bulge 508 cooperates with the compliant portion 504 to hold the drain body 220 within the drain coupling 230, preventing movement of the drain body 220, and likewise the blind drain installation assembly 200, in a direction generally along the central axis Z.
At 612, after the drain body 220 is threaded to the drain coupling 230, the toe tap 210 may be operably coupled to the drain body 220. The toe tap 210 may include a projection, shown as a toe tap fastener 510. The toe tap fastener 510 may be threaded. The toe tap fastener 510 is positioned to be concentric about the central axis Z. The toe tap fastener 510 is configured to be threaded to the coupling body orifice 465. The toe tap 210 is configured to interface with the drain body 220 such that the toe tap 210 can be positioned to selectively prevent a flow of water from flowing through the drain body 220, and likewise preventing a flow of water from flowing through the drain pipe 240. The toe tap 210 may be configured to be positioned to control a flow rate of a flow of water through the drain pipe 240. The toe tap 210 is also configured to prevent large foreign objects (e.g., rings, marbles, hair, soot, pills, etc.) from passing through the drain body 220 while still allowing water to flow through. In some embodiments, the toe tap 210 is configured to only allow water and other liquids with similar properties (e.g., drain cleaner, liquid soap, etc.) to pass through the drain body 220, and likewise the drain pipe 240.

The drain coupling 730 includes a generally annular first body 802 having a first upper end 804, a first lower end 806, a first outer surface 808, and a first inner surface 810. The first outer surface 808 and the first inner surface 810 may be concentric about the central axis Z. The first inner surface 810 defines an orifice (e.g., a flow path, etc.), shown as a coupling opening 812 configured to accept the drain pipe 240 and the drain body 720. The first inner surface 810 is configured to interface with the drain pipe 240 to provide a sealant such that a water-tight seal is formed between the drain coupling 730 and the drain pipe 240. The drain coupling 730 may include a plurality of annular projections 813 extending laterally away from the first inner surface 810 and toward the central axis Z. As shown in
Proximate the first lower end 806, the first inner surface 810 has a tenth diameter D10. The first inner surface 810 may maintain a circular cross-section of the tenth diameter D10 extending from the first lower end 806 to the first upper end 804. In some embodiments, the diameter of the first inner surface 810 proximate the first upper end 804 is different (e.g., greater, lesser, etc.) than the tenth diameter D10. The first inner surface 810 is configured to accept the drain body 720. The first inner surface 810 is also configured to allow a flow of water to pass through.

The first flange 814 includes a first flange first surface 816, a first flange second surface 818, and a first flange third surface 820. The first flange first surface 816 is disposed at an underside of the first flange 814 and is configured to cooperate and interface with the top basin surface 110 such that a water-tight seal is created between the first flange 814 and the top basin surface 110. The first flange first surface 816 extends laterally outwardly from and is generally perpendicular to and contiguous with the first outer surface 808. In some embodiments, the first flange first surface 816 projects outwardly from the first outer surface 808 at an angle that is not perpendicular. The first flange second surface 818 is contiguous with the first flange first surface 816. The first flange second surface 818 may be concentric about the center axis Z and may have the twelfth diameter D12. The first flange second surface 818 may be parallel with the first outer surface 808. The first flange third surface 820 is contiguous with the first flange second surface 818 and may be parallel to the first flange first surface 816. The first flange third surface 820 is disposed proximate the first upper end 804. The first flange third surface 820 is configured to interface with a portion of the drain body 720 to create a watertight seal between the drain coupling 730 and the drain body 720 such that a flow of water is prevented from flowing between the first flange third surface 820 and the drain body 720. The first flange third surface 820 is contiguous with the first inner surface 810. The first flange third surface 820 and the first inner surface 810 may meet at a corner. In some embodiments, the corner is chamfered (e.g., filleted, rounded, blunted, etc.) such that the transition between the first flange third surface 820 and the first inner surface 810 is uninterrupted (e.g., smooth, rounded, etc.).
The drain coupling 730 further includes a generally annular flange, shown as a first lattice 840. The first lattice 840 is similar to the coupling threads 330. A difference between the first lattice 840 and the coupling threads 330 is that the first lattice 840 is configured to accept the fastener 725. The first lattice 840 extends orthogonally away from the first inner surface 810 and is disposed approximately half-way between the first lower end 806 and the first upper end 804. In some embodiments, the plurality of annular projections 813 are disposed between the first lattice 840 and the first lower end 806. The first lattice 840 may be manufactured from brass, steel, aluminum, plastic, titanium, rubber, or similar materials. The first lattice 840 may be manufactured into the first inner surface 810 such that the drain coupling 730 and the first lattice 840 are a single body (e.g., all one piece, etc.). In some embodiments, the first lattice 840 is manufactured separately from the drain coupling 730 and later coupled to the drain coupling 730 by over-molding, fasteners, interference fit, friction, adhesives, glue, or by similar coupling means.
The first lattice 840 includes a generally planar top first lattice surface 842 and a generally planar bottom first lattice surface 844. Extending through both the top first lattice surface 842 and the bottom first lattice surface 844 may be a plurality of holes configured to allow a flow of water to pass through the drain coupling 730. As shown in
The drain coupling 730 may further include a plurality of holes (e.g., orifices, openings, etc.) shown as coupling holes 860. The coupling holes 860 extend through the first inner surface 810 and the first outer surface 808 such that the drain coupling 730 is in fluid communication with the overflow channel 140 when the drain coupling 730 is installed in the drain opening 130. Each one of the coupling holes 860 is defined by an annular coupling hole surface 862 that is contiguous with both the first inner surface 810 and the first outer surface 808. In some embodiments, the drain coupling 730 does not include the coupling holes 860. For example, coupling holes 860 may not be advantageous for use in an alternative wash basin 100 that does not include the overflow channel 140 or a similar overflow channel.

The drain body 720 includes a generally annular second body 902 having a second upper end 904, a second lower end 906, a second outer surface 908, and a second inner surface 910. The second outer surface 908 and the second inner surface 910 are concentric about the central axis Z. The second inner surface 910 defines a drain body opening 912 having a thirteenth diameter D13 proximate the second lower end 906. The drain body opening 912 maintains a circular cross-section of the thirteenth diameter D13 extending between the second upper end 904 and the second lower end 906. The second outer surface 908 maintains a circular cross-section of a fourteenth diameter D14 extending between the second upper end 904 and the second lower end 906. The fourteenth diameter D14 is less than the tenth diameter D10.
The drain body 720 further includes a generally annular second flange 914 extending laterally outwardly from (e.g., orthogonal to) the second outer surface 908. As shown in
The second flange 914 includes a second flange first surface 916, a second flange second surface 918, and a second flange third surface 920. The second flange first surface 916 is contiguous with and concentric about the second outer surface 908. In some embodiments, the second flange first surface 916 is perpendicular to the second outer surface 908. In other embodiments, the second flange first surface 916 meets the second outer surface 908 at an angle other than perpendicular. In some embodiments, the transition from second flange first surface 916 to the second outer surface 908 is rounded. This rounded interface between the second outer surface 908 and the second flange first surface 916 may assist in biasing the first flange 814 toward the surfaces defining the drain opening 130 to create a watertight seal between the top basin surface 110, the first flange 814, and the second flange 914.
The second flange first surface 916 is contiguous with the second flange second surface 918. The second flange second surface 918 may be concentric about the central axis Z. The second flange second surface 918 is contiguous with the second flange third surface 920. The second flange third surface 920 may meet the second flange first surface 916 at a corner such that there is no second flange second surface 918. In some embodiments, the second flange second surface 918 is chamfered such that the transition between the second flange first surface 916 and the second flange third surface 920 is smooth (e.g., rounded, uninterrupted, etc.). The second flange third surface 920 is also contiguous with the second inner surface 910. The second flange third surface 920 may be perpendicular to and concentric about the second inner surface 910. In some embodiments, where the second flange third surface 920 and the second inner surface 910 meet may be chamfered such that the transition from the second flange third surface 920 to the second inner surface 910 is uninterrupted by a sharp corner or similar discontinuity (e.g., smooth, rounded, continuous, etc.).
The drain body 720 further includes a generally annular flange, shown as a second lattice 940. The second lattice 940 extends laterally away from the second inner surface 910 and toward the central axis Z. As shown in
Extending through both the top second lattice surface 942 and the bottom second lattice surface 944 may be a plurality of openings configured to allow a flow of water to pass through the drain body 720, and likewise the drain coupling 730. As shown in

Referring to
The third upper end 952 may extend above the top second lattice surface 942 such that the third upper end 952 creates a projection (e.g., bump, etc.) on the second lattice 940. In some embodiments, the third upper end 952 is flush with top second lattice surface 942 such that there is no depression or bump. In some embodiments, the third upper end 952 may be disposed below the top second lattice surface 942 such that a depression is made in the second lattice 940.
The second coupling body 950 further includes an annular orifice concentric about the central axis Z that is defined by the third inner surface 958. The third inner surface 958 includes a third inner first portion 960 and a third inner second portion 962. The third inner first portion 960 is threaded to accept a threaded body, such as a fastener, preferably the toe tap fastener 510. The third inner first portion 960 defines a sixteenth diameter D16. When the toe tap fastener 510 is threadingly coupled to the third inner first portion 960 of the second coupling body 950, the toe tap fastener 510 rests flush with a bottom of the third inner first portion 960 (e.g., flush with a top of the third inner second portion 962). In some embodiments, when the toe tap fastener 510 is threadingly coupled to the second coupling body 950, a portion of the toe tap fastener 510 extends below the third inner first portion 960 and into the cavity defined by the third inner second portion 962.
Contiguous with the third inner first portion 960 is the third inner second portion 962, concentric about the central axis Z and defining a seventeenth diameter D17. The seventeenth diameter D17 is smaller than (e.g., less than, etc.) than the sixteenth diameter D16. The change in diameter between the third inner first portion 960 and the third inner second portion 962 aids in preventing the toe tap fastener 510 (e.g., any fastener with threads matching the pitch of the third inner first portion 960) from threading or extending into the third inner second portion 962.
Proximate the third lower end 954 and disposed within the third inner second portion 962 is a generally annular flange, shown as a third flange 970. The third flange 970 extends laterally away from the third inner surface 958 and inwardly toward the central axis Z. As shown in
The drain body 720 may further include overflow openings 990. The overflow openings 990 may extend through the second outer surface 908 and the second inner surface 910 such that a flow of water may exit the drain body 720 through the overflow openings 990. The overflow openings 990 are positioned at a height relative to the second flange 914 such that the overflow openings 990 are in fluid communication with the coupling holes 860 when the blind drain installation assembly 700 is installed. Each one of the overflow openings 990 is defined by an annular coupling hole surface 992 that is contiguous with both the second inner surface 910 and the second outer surface 908.

To begin installation, at 1102, the drain pipe 240 that extends through the floor opening 107 is cut such that the top drain pipe portion 245 is flush with the top of the floor 105. At 1104, the wash basin 100 is then positioned on the floor 105 and above the drain pipe 240 such that the drain pipe 240 and the drain opening 130 are lined up (e.g., concentric about each other).
At 1106, the drain coupling 730 is extended through the drain opening 130 and positioned around the drain pipe 240. The drain coupling 730 extends through the floor opening 107 and below the floor 105. The first lattice 840 is positioned between the drain opening 130 and the top drain pipe portion 245. In some embodiments, the top drain pipe portion 245 may be disposed below the floor 105. In such embodiments, the first lattice 840 may be positioned below the floor 105. The first flange 814 rests on the top basin surface 110 such that the drain coupling 730 does not fall through the drain opening 130.
At 1108, the drain body 720 is disposed within the drain coupling 730 such that the second flange 914 rests on top of the first flange 814. Further, the second coupling body 950 is positioned to be concentric about the first orifice 855. In some embodiments, the second coupling body 950 extends into the first lattice 840 to aid in the alignment of the second coupling body 950 with the first orifice 855. In some embodiments, the second coupling body 950 has a non-circular cross-section (e.g., square, ellipse, hexagonal, etc.) and extends into the first lattice 840 such that the rotation of the drain body 720 is prevented relative to the drain coupling 730 during installation.
At 1110, the fastener 725 is inserted through the second coupling body 950. At 1112, the fastener 725 is threadingly coupled to the first orifice 855. As shown in

The drain coupling 1230 includes a generally annular first body 1302 having a first upper end 1304, a first lower end 1306, a first outer surface 1308, and a first inner surface 1310. The first outer surface 1308 and the first inner surface 1310 may be concentric about the central axis Z. The first outer surface 1308 may be configured to interface with the drain pipe 240 to provide a sealant such that a water-tight seal is formed between the drain coupling 1230 and the drain pipe 240. In some embodiments, the drain coupling 1230 is configured to be inserted into (e.g., received by) the drain pipe 240. The first outer surface 1308 may include a plurality of annular projections 1313 extending laterally away from the first outer surface 1308. As shown in
Proximate the first lower end 1306, the first inner surface 1310 has a nineteenth diameter D19. The first inner surface 1310 may maintain a circular cross-section of the nineteenth diameter D19 extending from the first lower end 1306 to the drain body catch 1311. In some embodiments, the diameter of the first inner surface 1310 proximate the first upper end 1304, shown as a twentieth diameter D20, is greater than the nineteenth diameter D19. The first inner surface 1310 is configured to allow a flow of water to pass through.
The drain coupling may further include a stop lip 1308b configured to interface with the drain pipe top 245 to prevent the drain coupling 1230 from sliding too deeply within the drain pipe 240. The stop lip 1308b may serve to transition the first outer surface 1308 between the twenty-first diameter D21 and the twenty-second diameter D22. The stop lip 1308b may be structured to sit on top of the drain pipe 240 during installation. In some embodiments, the stop lip 1308b defines little more than a change in thickness of the drain coupling 1230. While the portion of the drain coupling 1230 inserted into the drain pipe 240 may have one thickness, it may be desirable for the portion of the drain coupling 1230 extending out of the drain pipe 240 to have a different, and possibly greater, thickness. Varying the thickness of the portion of the drain coupling 1230 extending out of the drain pipe 240 may affect the compliance of the drain coupling 1230, and thus the resulting forces of a squeeze bulge of the drain coupling 1230 formed during installation.
The drain coupling 1230 may further include generally annular first flange 1314 extending laterally outwardly from (e.g., orthogonally to) the first outer surface 1308. As shown in
The first flange 1314 includes a first flange first surface 1316, a first flange second surface 1318, and a first flange third surface 1320. The first flange first surface 1316 is disposed at an underside of the first flange 1314 and is configured to cooperate and interface with the top basin surface 110 such that a water-tight seal is created between the first flange 1314 and the top basin surface 110. The first flange first surface 1316 extends laterally outwardly from and is generally perpendicular to and contiguous with the first outer surface 1308. In some embodiments, the first flange first surface 1316 projects outwardly from the first outer surface 1308 at an angle that is not perpendicular. The first flange second surface 1318 is contiguous with the first flange first surface 1316. The first flange second surface 1318 may be concentric about the center axis Z and may have the twenty-third diameter D23. The first flange second surface 1318 may be parallel with the first outer surface 1308. The first flange third surface 1320 is contiguous with the first flange second surface 1318 and may be parallel to the first flange first surface 1316. The first flange third surface 1320 is disposed proximate the first upper end 1304. The first flange third surface 1320 is configured to interface with a portion of the drain body 1220 to create a watertight seal between the drain coupling 1230 and the drain body 1220 such that a flow of water is prevented from flowing between the first flange third surface 1320 and the drain body 1220. The first flange third surface 1320 is contiguous with the first inner surface 1310. The first flange third surface 1320 and the first inner surface 1310 may meet at a corner. In some embodiments, the corner is chamfered (e.g., filleted, rounded, blunted, etc.) such that the transition between the first flange third surface 1320 and the first inner surface 1310 is uninterrupted (e.g., smooth, rounded, etc.).
The drain coupling 1230 may further include a generally annular second flange, shown as a centering ring 1324, extends laterally outwardly from (e.g., orthogonally to) the first outer surface 1308 and defines a twenty-fourth diameter D24. As shown in
The drain coupling 1230 further includes a generally annular flange, shown as a first lattice 1340. The first lattice 1340 is similar to the first lattice 840. A difference between the first lattice 1340 and the first lattice 840 is that the first lattice 1340 is configured to cooperate with a nut to couple a latch body to the first lattice 1340. The first lattice 1340 extends orthogonally away from the first inner surface 1310 and may be disposed approximately half-way between the first lower end 1306 and the first upper end 1304. In some embodiments, the first lattice 1340 is positioned nearer the first upper end 1304 than the first lower end 1306. In some embodiments, the annular projections 1313 extend between the first lower end 1306 and the first lattice 1340. In some embodiments, the stop lip 1308b is positioned nearer the first lower end 1306 than the first lattice 1340. This structure may be desirable to prevent the first lattice 1340 from being disposed within the drain pipe 240, preventing undue stress on the first lattice 1340 that may be caused as a result of improperly forcing the first lattice 1340 within the drain pipe 240. In some embodiments, the position of the stop lip 1308b may not depend upon the positon of the first lattice 1340. The first lattice 1340 may be manufactured from brass, steel, aluminum, plastic, titanium, rubber, or similar materials. The first lattice 1340 may be manufactured into the first inner surface 1310 such that the drain coupling 1230 and the first lattice 1340 are a single body (e.g., all one piece, etc.). In some embodiments, the first lattice 1340 is manufactured separately from the drain coupling 1230 and later coupled to the drain coupling 1230 by over-molding, fasteners, interference fit, friction, adhesives, glue, or by similar coupling means.

The first arm 1408 is also coupled to the first compliant portion 1412 proximate the first arm second end 1410. As shown in
Extending away from the first compliant portion 1412 is the first finger 1416. The first finger 1416 may extend perpendicularly away from the first compliant portion 1412 in a direction generally parallel to the first arm 1408. The first finger 1416 may include a triangular base portion, shown as a first finger base 1417. The contour of the first finger base 1417 may add rigidity to the first finger 1416 such that more force would be required to bias the first finger 1416 toward the central axis Z, and thus toward the first arm 1408, than would be required by a finger not having a contoured finger base. The contours and the profile of the first finger base 1417 may be adjusted to meet the installation needs of the drain coupling 1230. The first finger base 1417 may be manufactured to have a wider (e.g., thicker) profile, such as to increase the rigidity of the first finger 1416. In some embodiments, the first finger base 1417 may be thinned (e.g., made less thick, made less wide, etc.) such as to decrease the rigidity of the first finger 1416 and lowering the amount of force required to bias the first finger 1416 toward and away from the central axis Z.

The latch body 1400 may further include a second arm 1428, a second compliant portion 1432, a second finger 1436, and a second latch 1440. The second arm (e.g., cantilever) 1428 includes a second arm first end 1429 and a second arm second end 1430. The second arm first end 1429 is coupled to the ring 1404 such that the second arm 1428 extends perpendicularly away from the ring 1404 in a direction generally away from the first lattice 1340. In some embodiments, the second arm 1428 is contiguous with the ring 1404 at a rounded corner such as to disperse stress concentrations caused at the interface between the ring 1404 and the second arm 1428 when the second arm 1428 is biased toward and away from the central axis Z. The second arm 1428 and the ring 1404 may be manufactured from a single piece of metal, plastic, polymer, wood, or similar material.
The second arm 1428 is also coupled to the second compliant portion 1432 proximate the second arm second end 1430. As shown in
Extending away from the second compliant portion 1432 is the second finger 1436. The second finger 1436 may extend perpendicularly away from the second compliant portion 1432 in a direction generally parallel to the second arm 1428. The second finger 1436 may include a triangular base portion, shown as a second finger base 1437. The contour of the second finger base 1437 may add rigidity to the second finger 1436 such that more force would be required to bias the second finger 1436 toward the central axis Z, and thus toward the second arm 1428, than would be required by a finger not having a contoured finger base. In some embodiments, the first finger base 1417 and the second finger base 1437 have different contours are profiles, allowing the first finger 1416 to demonstrate different properties (e.g., force to bias, rigidity, cycle life, etc.) than the second finger 1436. The contours and the profile of the second finger base 1437 may be adjusted to meet the installation needs of the drain coupling 1230. The second finger base 1437 may be manufactured to have a wider (e.g., thicker) profile, such as to increase the rigidity of the second finger 1436. In some embodiments, the second finger base 1437 may be thinned (e.g., made less thick, made less wide, etc.) such as to decrease the rigidity of the second finger 1436 and lowering the amount of force required to bias the second finger 1436 toward and away from the central axis Z.

The drain body 1220 includes a generally annular second body 1502 having a second upper end 1504, a second lower end 1506, a second outer surface 1508, and a second inner surface 1510. The second outer surface 1508 and the second inner surface 1510 are concentric about the central axis Z. The second outer surface 1508 has a circular cross-section of a twenty-fifth diameter D25 proximate the second upper end 1504. The twenty-fifth diameter D25 is approximately equal to the twentieth diameter D20. Generally, the drain body 1220 may be shaped to be accepted by the drain coupling 1230. More specifically, the second outer surface 1508 may be shaped to interface with the second inner surface first portion 1310b.
The drain body 1220 further includes a generally annular second flange 1514 extending laterally outwardly from (e.g., orthogonal to) the second outer surface 1508. As shown in
The second flange 1514 includes a second flange first surface 1516, a second flange second surface 1518, and a second flange third surface 1520. The second flange first surface 1516 is contiguous with and concentric about the second outer surface 1508. In some embodiments, the second flange first surface 1516 is perpendicular to the second outer surface 1508. In other embodiments, the second flange first surface 1516 meets the second outer surface 1508 at an angle other than perpendicular. In some embodiments, the transition from second flange first surface 1516 to the second outer surface 1508 is rounded. This rounded interface between the second outer surface 1508 and the second flange first surface 1516 may assist in biasing the first flange 1314 toward the surfaces defining the drain opening 130 to create a watertight seal between the top basin surface 110, the first flange 1314, and the second flange 1514.
The second flange first surface 1516 is contiguous with the second flange second surface 1518. The second flange second surface 1518 may be concentric about the central axis Z. The second flange second surface 1518 may extend below the second flange first surface 1516, forming a tooth 1519. The tooth 1519 may be structured to grip into the first flange 1314, improving the contact between the first flange 1314 and the top basin surface 110. The tooth 1519 may also prevent rotational motion of the drain body 1220 relative to the drain coupling 1230 during installation or regular use. In embodiments where the twenty-sixth diameter D26 may be slightly greater than the twenty-third diameter D23, the tooth 1519 may direct the squeeze of the first flange 1314 downward and toward the top basin surface 110, improving the contact between the top basin surface 110 and the first flange 1314, and further improving the aesthetic appearance of the installed blind drain installation assembly 1200 by preventing the first flange 1314 from squeezing beyond the second flange 1514 and within sight of a viewer from within the wash basin 100.
The second flange second surface 1518 is contiguous with the second flange third surface 1520. The second flange third surface 1520 may meet the second flange first surface 1516 at a corner such that there is no second flange second surface 1518. In some embodiments, the second flange second surface 1518 is chamfered such that the transition between the second flange first surface 1516 and the second flange third surface 1520 is smooth (e.g., rounded, uninterrupted, etc.). The second flange third surface 1520 is also contiguous with the second inner surface 1510. The second flange third surface 1520 may be perpendicular to and concentric about the second inner surface 1510. In some embodiments, where the second flange third surface 1520 and the second inner surface 1510 meet may be chamfered such that the transition from the second flange third surface 1520 to the second inner surface 1510 is uninterrupted by a sharp corner or similar discontinuity (e.g., smooth, rounded, continuous, etc.).
The drain body 1220 further includes a generally annular flange, shown as a third flange (e.g., body flange) 1540. The third flange 1540 extends laterally away from the second inner surface 1510 and toward the central axis Z. As shown in
Interrupting the third flange 1540 is a first cut-out 1550 and a second cut-out 1554. As shown in
Referring now to
The first hook 1553 has a first hook intrados 1560, a first hook extrados 1562, and a first hook end 1564. The first hook 1553 latches to (e.g., hooks onto, etc.) the first latch 1420. Preferably, when the blind drain installation assembly 1200 is fully assembled, the first hook end 1564 interfaces with the first latch intrados 1424, and the first latch end 1426 interfaces with the first hook intrados 1560. However, slight variations in manufacturing may cause only one such interface to occur (e.g., the first latch end 1426 is shorter than the first hook end 1564, causing the first hook end 1564 to interface with the first latch intrados 1424, such that the first latch end 1426 does not interface with the first hook intrados 1560, and vice versa).
Similarly, the second hook 1557 has a second hook intrados 1570, a second hook extrados 1572, and a second hook end 1574. The second hook 1557 latches to (e.g., hooks onto, etc.) the second latch 1440. Preferably, when the blind drain installation assembly 1200 is fully assembled, the second hook end 1574 interfaces with the second latch intrados 1444, and the second latch end 1446 interfaces with the second hook intrados 1570. However, slight variations in manufacturing may cause only one such interface to occur (e.g., the second latch end 1446 is shorter than the second hook end 1574, causing the second hook end 1574 to interface with the second latch intrados 1444, such that the second latch end 1446 does not interface with the second hook intrados 1570, and vice versa).
In embodiments where the first fixture projection 1350 and the second fixture projection 1360 allow for the drain body 1220 to be positioned within the drain coupling 1230 in two positions, separated by 180 degrees, it may occur that the first hook 1553 interfaces with the second latch 1440 and the second hook 1557 interfaces with the first latch 1420.
The drain body 1220 may further include a second overflow aperture 1580. The second overflow aperture 1580 extends through the second inner surface 1510 and the second outer surface 1508. The second overflow aperture 1580 may be in fluid communication with the first overflow aperture 1365 of the drain coupling 1230. As shown in

Once the drain coupling 1230 is inserted such that the first flange 1314 interfaces with the top basin surface 110, the drain body 1220 may be inserted into the drain coupling 1230. In some embodiments, the drain body 1220 is already coupled to the drain coupling 1230, such as by over-molding, prior to the drain coupling 1230 being inserted through the drain opening 130. In some embodiments, the drain body 1220 may be inserted into the drain coupling 1230 such that the first fixture projection 1350 is properly seated within (e.g., is received within) the first cut-out 1550, and the second fixture projection 1360 is properly seated within the second cut-out 1554, aligning the drain body 1220 within the drain coupling 1230. In some embodiments, the drain body 1220 is inserted into the drain coupling 1230 from the top side of the wash basin 100 until the third flange 1540 (e.g., the bottom third flange surface 1544) interfaces with the drain body catch 1311. When properly inserted, the first hook 1553 may be proximate, and in some instances interfacing with, the first fixture projection seat portion 1356, and the second hook 1557 may be proximate, and in some instances interfacing with, the second fixture projection seat portion 1366. More specifically, the first hook extrados 1562 may interface with the first fixture projection seat portion 1356 and the second hook extrados 1572 may interface with the second fixture projection seat portion 1366. In some embodiments, the drain body 1220 is fully seated when the second flange 1514 interfaces with the first flange 1314.

The fixture plate 1608 is placed over the drain body 1220, interfacing with the second flange 1514. The fastener 1606 is slid through the fixture plate 1608 and threaded into the nut 1368 from above. An installer may use a tool (e.g., wrench, screwdriver, pliers, etc.) to turn the fastener 1606, causing the nut 1368 to thread onto the fastener 1606 and transverse up the fastener 1606, along the central axis Z, in the direction of the fixture plate 1608. With the nut 1368 also moves the first lattice 1340 and the latch body 1400. More specifically, the first latch 1420 moves toward the first hook 1553 and the second latch 1440 moves toward the second hook 1557. Eventually, the first latch extrados 1422 and the first hook extrados 1562 may contact each other. The rounded profile of first hook 1553 biases the first finger 1416 toward the central axis Z as the latch body 1400 continues to travel upward, toward the fixture plate 1608. Similarly, the second latch extrados 1442 and the second hook extrados 1572 may contact each other. The rounded profile of second hook 1557 biases the second finger 1436 toward the central axis Z as the latch body 1400 continues to travel upward, toward the fixture plate 1608. Eventually, as the nut 1368 is further threaded up the fastener 1606, the first latch end 1426 will interface with the first hook end 1564 and the second latch end 1446 will interface with the second hook end 1574. Once the first latch end 1426 passes the first hook end 1564 (e.g., is traversed nearer to the top basin surface 110, beyond the first hook end 1564 as a result of the threading of the nut 1368) and the second latch end 1446 passes the second hook end 1574, the first finger 1416 will bias the first latch 1420 away from the central axis Z and the second finger 1436 will bias the second latch 1440 away from the central axis Z. The first latch end 1426 will be positioned above the first hook intrados 1560 and the second latch end 1446 will be positioned above the second hook intrados 1570. The installer should feel a sudden drop in resistance in the turning of the fastener 1606 once the pressure is released from the first finger 1416 and the second finger 1436. The installer may possibly hear a snap or a click when the first finger 1416 and the second finger 1436 fling into the first hook 1553 and the second hook 1557, respectively. In some embodiments, at this point in the installation, neither the first latch 1420 nor the second latch 1440 are properly seated. At this point, the installer may reverse the fastener 1606, causing the first latch 1420 and the second latch 1440 to move down, toward the drain pipe 240, eventually being properly seated with the first hook 1553 and the second hook 1557, respectively, as previously described. The installer may be able to feel when the first latch 1420 and the second latch 1440 are properly seated, as the fastener will begin to thread out of the nut 1368 and travel in a direction away from the drain pipe 240, along the central axis Z.
In some embodiments, such as shown in
The movement of the nut 1368 toward the top basin surface 110 along the central axis Z is allowed because of the compliance of the drain coupling 1230. As the fastener 1606 is threaded into the nut 1368, the first lattice 1340 travels up, in the direction of the top basin surface 110, and squeezes the side walls of the drain coupling 1230 against the bottom basin surface 120. The drain body 1220, and more specifically the second flange 1514, may be compressed against the first flange 1314 as a result of the compliance of the drain coupling 1230 during installation. The second flange 1514 compresses the first flange 1314 into the top basin surface 110, forming a watertight seal between the top basin surface 110 and the first flange 1314. In some embodiments, a watertight seal may also be formed between the second flange 1514 and the first flange 1314.

Extending between the first cover end 1706 and the second cover end 1708 is a neck 1710. The neck 1710 is configured to protect (e.g., cover) the first finger 1416 from foreign bodies. In some embodiments, the neck 1710 may interface with the first finger 1416 once the blind drain installation assembly 1200 is assembled, as shown in
Proximate the first cover end 1706, the neck 1710 may be coupled to a head 1712. The head 1712, once installed within the blind drain installation assembly 1200, may be configured to interface with the first latch 1420. In some embodiments, the head 1712 interfaces with the second inner surface 1510 of the drain body 1220, displacing the head 1712 apart from the first latch 1420 such that the head 1712 does not interface with the first latch 1420. The interface between the head 1712 and the neck 1710 may be chamfered or rounded to provide a smooth transition. The smooth transition may serve to prevent foreign bodies from attaching to and/or dislodging the finger guard 1700 from the blind drain installation assembly 1200.
Proximate the second cover end 1708, the finger guard 1700 includes a cover base surface 1714 configured to interface with the top first lattice surface 1342 to prevent movement of the finger guard 1700 in a direction generally toward the drain pipe 240. The finger guard 1700 also includes a cover base contour 1716 configured to dissipate stresses caused by forces on the finger guard 1700 in a direction generally toward the central axis Z. The finger guard 1700 may further include walls 1718 extending the length of the neck 1710 and the head 1712, the walls 1718 further configured to prevent access to the first finger 1416 by foreign bodies.
The cantilever portion 1704 may include a first cantilever 1720 and a second cantilever 1722. The first cantilever 1720 may include a first catch surface 1724. The first catch surface 1724 may be configured to interface with the bottom first lattice surface 1344 to prevent movement of the finger guard 1700 in a direction generally toward the top basin surface 110. A distance between the first catch surface 1724 and the cover base surface 1714 may be approximately equal to a thickness of the first lattice 1340. In some embodiments, the distance between the first catch surface 1724 and the cover base surface 1714 may be slightly greater than the thickness of the first lattice 1340, allowing for a bit of movement of the finger guard 1700 when installed. The second cantilever 1722 may include a second catch surface 1726, similar to the first catch surface 1724 and configured to interface with the bottom first lattice surface 1344 and configured to prevent movement of the finger guard 1700 in a direction generally toward the top basin surface 110.

The finger guard 1700, when used and installed in cooperation with the blind drain installation assembly 1200, may be installed after the installation fixture 1604 has been removed, but before the top tap 210 has been inserted within the drain body 1220. The finger guard 1700 is inserted, from above (e.g., within the wash basin 100), such that the cantilever portion 1704 extends through the lattice slot 1370. More specifically, the first cantilever 1720 and the second cantilever 1722 are biased toward one another such that both the first cantilever 1720 and the second cantilever 1722 may be extended through the lattice slot 1370. The cantilever portion 1704 is properly set within the lattice slot 1370 when both the first catch surface 1724 and the second catch surface 1726 are biased away from one another and interface with the bottom first lattice surface 1344. In some embodiments, the finger guard 1700 is properly set when the cover base surface 1714 interfaces with the top first lattice surface 1342. In some embodiments, the finger guard 1700 is properly set when both of the previous conditions are met.
Once the finger guard 1700 is installed, the first cantilever 1720 and the second cantilever 1722 act as covers for the first compliant portion 1412. The first cantilever 1720 and the second cantilever 1722 may serve to prevent build-up of debris from collecting on the first compliant portion 1412 and inhibiting movement of the first finger 1416.

To begin installation, at 1802, the drain pipe 240 that extends through the floor opening 107 is cut such that the top drain pipe portion 245 is flush with the top of the floor 105. At 1804, the wash basin 100 is then positioned on the floor 105 and above the drain pipe 240 such that the drain pipe 240 and the drain opening 130 are lined up (e.g., concentric about each other).
At 1806, the drain coupling 1230 is extended through the drain opening 130 and extended through the drain pipe 240. The drain coupling 1230 extends through the floor opening 107 and below the floor 105. The first lattice 1340 is positioned between the drain opening 130 and the top drain pipe portion 245. In some embodiments, the top drain pipe portion 245 may be disposed below the floor 105. In such embodiments, the first lattice 1340 may be positioned below the floor 105. The first flange 1314 rests on the top basin surface 110 such that the drain coupling 1230 does not fall through the drain opening 130.
At 1808, the drain body 1220 is disposed within the drain coupling 1230 such that the second flange 1514 rests on top of the first flange 1314. Further, the latch body 1400 is positioned below the drain body 1220. In some embodiments, the drain body 1220 interfaces with the first fixture projection 1350 second fixture projection 1360 to align the drain body 1220 within the drain coupling 1230 such that, for example, the first overflow aperture 1365 is aligned with the second overflow aperture 1580. In some embodiments, the first fixture projection 1350 and the second fixture projection 1360 interface with the drain body 1220 to prevent rotational movement of the drain body 1220 about the central axis Z relative to the drain coupling 1230.
At 1810, the installation fixture 1604 (or a similar installation fixture) is extended through the drain body 1220 and the drain coupling 1230 from above (e.g., from within the wash basin 100). The installation fixture 1604 interfaces with the second flange third surface 1520, and threads into the nut 1368. As the installation fixture 1604 is threaded into the nut 1368, the nut 1368 traverses up the installation fixture 1604, bringing with it the first lattice 1340 and the latch body 1400. The installation fixture 1604 is threaded into the nut 1368 until the first latch 1420 is positioned above the first hook 1553 and the second latch 1440 is positioned above the second hook 1557. In some embodiments, in which the drain body 1220 does not include the first hook 1553 or the second hook 1557, the installation fixture 1604 is threaded into the nut 1368 until the first latch 1420 and the second latch 1440 are positioned above the third flange 1540. The movement of the first lattice 1340 toward the wash basin 100 forms the squeeze bulge 1610 within the drain coupling 1230.
At 1812, the installation fixture is removed from the drain coupling 1230 and the drain body 1220 (e.g., unthreaded from the nut 1368).
At 1814, the toe tap 210 is operably coupled to the blind drain installation assembly 1200. In some embodiments, the toe tap includes the toe tap fastener 510, configured to threading couple to the nut 1368.
