DETAILED DESCRIPTION

Introduction

[0022] With reference to FIG. 1, an example drain assembly 10 is shown. As will be explained in more detail below, the drain assembly 10 may be used with, or assembled with, a swimming pool construct 12 to perform various functions relative to water in the pool construct 12. For example, the drain assembly 10 may help facilitate water circulation within the pool construct 12, remove debris (e.g., dirt, hair, leaves, bugs, among others) from the water within the pool construct 12, and/or allow for a desired water level within the pool construct 12, among others.

[0023] With reference to FIG. 2, the drain assembly 10 may include a housing assembly 20, a cover assembly 30, an insert 40, a hydrostatic valve 50, a valve stake 60, and/or a plug 70, among others. Referring again to FIG. 1, in an assembled configuration, the cover assembly 30 may be removably coupled to the housing assembly 20. In various implementations, removing the cover assembly 30 from the housing assembly 20 permits a user to access various components (e.g., the insert 40, the hydrostatic valve 50, the valve stake 60, and/or the plug 70) of the drain assembly disposed in the housing assembly 20.

Housing Assembly

[0024] With reference to FIG. 3, in various implementations, the housing assembly 20 may include an outer housing 80 and an inner housing 82. In some example configurations, the inner housing 82 may be disposed within and/or removably coupled to the outer housing 80. In some instances, the inner housing 82 may be secured (e.g., fixed) to the outer housing 80. For example, the inner housing 82 may be secured to outer housing 80 via a snap fit connection, an adhesive, one or more fasteners, and/or welding, among others.

[0025] With reference to FIGS. 4 and 5, the outer housing 80 may comprise one or more of a variety of shapes, sizes, configurations, and/or materials. In various implementations, the outer housing 80 may include a base 90 and one or more first sidewalls 92 (e.g., first sidewalls 92-1 to 92-4) that extend from the base 90. The base 90 and the first sidewalls 92 may define a cavity 94 that receives the inner housing 82.

[0026] In various implementations, the first sidewalls 92 may be arranged in a polygonal-shaped configuration (e.g., square, rectangle, etc.). In various implementations, the base 90 may include and/or may define a first outlet 96-1, a second outlet 96-2, and a third outlet 96-3, among others. The first outlet 96-1 may be disposed in the center and/or in the middle of the base 90. The first outlet 96-1 may connect with a pipe of a filtration system of the pool construct 12. The second outlet 96-2 may connect with the plug 70 or a pipe of the filtration system. The third outlet 96-3 may connect with the valve stake 60. While the outer housing 80 is generally shown and described herein as including three outlets, the outer housing 80 may include more or less than three outlets.

[0027] Referring now to FIG. 4, in various implementations, the outer housing 80 includes a plurality of protrusions 98 that extend from the base 90. The protrusions 98 may facilitate the alignment and/or connection of the outer housing 80 with the inner housing 82. For example, the protrusions 98 may define a plurality of slots 100 that may receive corresponding portions of the inner housing 82. Alternatively, the protrusions 98 may be received by corresponding portions of the inner housing 82. In some implementations, the base 90 defines one or more apertures 102. As illustrated in FIG. 4, the apertures 102 may be surrounded by one or more of the protrusions 98. In the assembled configuration within the pool construct 12, the apertures 102 may be filled with a material (e.g., concrete) that forms a portion of the pool construct 12 and secures the drain assembly 10 to the pool construct 12.

[0028] As illustrated in FIG. 3, in some example configurations, the outer housing 80 includes a plurality of fins 104. In various implementations, each first sidewall 92 (e.g., first sidewalls 92-1 to 92-4) may include one or more fins 104. In some instances, the fins 104 of a first sidewall 92 may be arranged parallel to each other. In various implementations, the fins 104 increase the rigidity of the housing assembly 20.

[0029] With reference to FIGS. 3 and 6, the inner housing 82 may comprise one or more of a variety of shapes, sizes, configurations, and/or materials. In various implementations, the inner housing 82 may include one or more second sidewalls 110 (e.g., second sidewalls 110-1 to 110-4), a center hub 112 disposed inward relative to the second sidewalls 110, and a plurality of inner portions 114 that are connected to (i.e., formed integrally with) the second sidewalls 110 and the center hub 112. In various implementations, the center hub 112 may be disposed in the center and/or in the middle of the inner housing 82.

[0030] In various implementations, the second sidewalls 110 and/or the center hub 112 may define a polygonal-shaped configuration (e.g., square, rectangle, etc.). In some example configurations, at least some of the inner portions 114 may include a rib 116. The rib 116 may be received by a slot 100 of the outer housing 80 to facilitate the alignment and/or connection of the inner housing 82 with the outer housing 80.

[0031] In various implementations, the insert 40 may be removably disposed in the center hub 112. In some instances, a cover 118 may be removably coupled to the center hub 112. In various implementations, the hydrostatic valve 50 may be removably coupled to the inner housing 82. For example, as illustrated in FIG. 10, one or more inner portions 114 may define a hole 120. In some implementations the hole 120 may be defined by a periphery of the inner portions 114 that extends about a central axis extending substantially (e.g., +/10 degrees) perpendicular to a central axis of the second outlet 96-2. The hydrostatic valve 50 may be at least partially disposed in the hole 120 such that the valve 50 in insertable into, and removable from, the hole 120 in a direction substantially parallel to the central axis of the hole 120. In various implementations, removing the cover 118 from the center hub 112 permits a user to access the insert 40. In various implementations, removing the cover 30 and/or the insert 40 permits a user to access the hydrostatic valve 50 (e.g., via the center hub 112).

[0032] With reference to FIG. 3, in an assembled configuration, the inner housing 82 is connected with the outer housing 80 such that the inner portions 114 and portions 122 of the base 90 define a plurality of fluid conduits 124 such as a first fluid conduit 124-1, a second fluid conduit 124-2, a third fluid conduit 124-3, and a fourth fluid conduit 124-4. The first fluid conduit 124-1, the second fluid conduit 124-2, the third fluid conduit 124-3, and the fourth fluid conduit 124-4 may each extend in an arcuate manner such that the plurality of fluid conduits 124 collectively define a vortex-shaped configuration. While the drain assembly 10 is generally shown and described herein as including four fluid conduits 124, the drain assembly 10 may include more or less than four fluid conduits 124.

[0033] In various implementations, in the assembled configuration, the second sidewalls 110 are offset from the first sidewalls 92 defining a void 126 therebetween. In some example configurations, the void 126 may extend continuously and uninterrupted along an entire perimeter of the housing assembly 20. In the assembled configuration, the void 126 is in fluid communication with the fluid conduits 124 and the center hub 112.

[0034] With reference to FIG. 12, in various implementations, the drain assembly 10 may include a first disposable component 106A and/or a second disposable component 106B, among others. In various implementations, the first disposable component 106A may be disposed in the void 126 and/or the second disposable component 106B may be disposed in the center hub 112. The first disposable component 106A and/or the second disposable component 106B prevent debris (e.g., dirt, rocks, pebbles, cement, etc.) from entering the fluid conduits 124 and/or the center hub 112 during installation and/or assembly of the drain assembly 10 in the pool construct 12. The first disposable component 106A and/or the second disposable component 106B are removed and discarded prior to operation of the drain assembly 10.

Cover Assembly

[0035] Referring again to FIG. 1, the cover assembly 30 may be detachably coupled to the housing assembly 20. In various implementations, the cover assembly 30 may connect with at least one of the outer housing 80 or the inner housing 82. The cover assembly 30 may be adjustable relative to the housing assembly 20. For example, the cover assembly 30 may be rotatable relative to at least one of the outer housing 80 or the inner housing 82 such that the cover assembly 30 may be aligned with a portion (e.g., a floor or a wall) of the pool construct 12. In the assembled configuration, the cover assembly 30 may be connected with the housing assembly 20 such that fluid from the pool construct 12 is permitted to flow through the void 126 of housing assembly 20.

Insert

[0036] With reference to FIGS. 7 and 10, in various implementations, the insert 40 may include and/or may define a fluid diverter 130. In some example configurations, the fluid diverter 130 may define a cone-shaped configuration. In some example configurations, the fluid diverter 130 defines a central axis A1 and includes a concave outer surface 132 surrounding the axis A1. In the assembled configuration, the insert 40 may be connected with and/or may be at least partially disposed within the center hub 112. The insert 40 may be disposed adjacent the first outlet 96-1. The fluid diverter 130 may guide fluid flowing through the plurality of fluid conduits 124 into the first outlet 96-1.

Hydrostatic Valve and Valve Stake

[0037] With continued reference to FIG. 10, in various implementations, the hydrostatic valve 50 may be removably coupled to the inner housing 82, and the valve stake 60 may be removably coupled to the outer housing 80. In the assembled configuration, the hydrostatic valve 50 is in fluid communication with the valve stake 60. The hydrostatic valve 50 and the valve stake 60 are in fluid communication with the plurality of fluid conduits 124.

[0038] In various implementations, the hydrostatic valve 50 regulates pressure in the fluid conduits 124. For example, during operation of the drain assembly 10, fluid from the environment (e.g., groundwater) external to the drain assembly 10 may flow through the hydrostatic valve 50 and into the fluid conduits 124 and/or the second outlet 96-2 when a fluid pressure in the environment exceeds a pressure threshold in the fluid conduits 124. In some implementations, fluid may be permitted to flow through the hydrostatic valve 50 and out of the valve stake 60 when a fluid pressure in the fluid conduits 124 exceeds a pressure threshold to reduce the pressure in the fluid conduits 124. In some examples, high fluid pressure in the fluid conduits 124 may cause damage to the drain assembly 10 and/or may cause the drain assembly 10 to operate incorrectly. In various implementations, fluid is inhibited from flowing through the hydrostatic valve 50 when the fluid pressure in the fluid conduits is less than the pressure threshold.

Plug

[0039] With reference to FIG. 11, in various implementations, the plug 70 may be removably coupled to the outer housing 80. For example, the plug 70 may be removably disposed in the second outlet 96-2 to inhibit fluid from flowing through the second outlet 96-2 when the second outlet 96-2 is not in operation. In some example configurations, the plug 70 may be disposed within the second outlet 96-2 such that an outer surface 140 of the plug 70 is aligned flush with an inner surface 142 of the outer housing 80. This alignment enables fluid to flow uninterrupted through a fluid conduit (e.g., fluid conduit 124-2).

Operation of Drain Assembly

[0040] With reference to FIGS. 8, 9, and 10, during operation of the drain assembly 10, fluid (e.g., water from the pool construct 12) is permitted to flow through the void 126, into and through the fluid conduits 124 (e.g., fluid conduits 124-1 to 124-4), into the center hub 112, and out of the first outlet 96-1. In various implementations, radiuses of the fluid diverter 130 may guide the fluid flowing through the fluid conduits 124 into the first outlet 96-1. In this regard, the fluid conduits 124 may each extend in a clockwise manner from the void 126 to the central hub 112.

[0041] In various implementations, the vortex arrangement of the fluid conduits 124 provides various operational benefits for the drain assembly 10. For example, the vortex arrangement of the fluid conduits 124 permits fluid and debris disposed in the fluid to flow smoothly, efficiently, and/or uninterrupted through the drain assembly 10. The foregoing enables efficient circulation and optimal filtration of the pool construct 12.

[0042] In various implementations, the vortex arrangement inhibits debris buildup in the drain assembly 10 such that stagnant water in the pool construct 12 is reduced. In various implementations, each fluid conduit 124 includes a curved configuration that has a length (e.g., length 150) from a respective sidewall 110 of the inner housing 82 to the center hub 112 that is greater than a length (e.g., length 152) of a straight line from the sidewall to the center hub 112 (see, e.g., FIG. 3). The longer length of each fluid conduit 124 inhibits hair and/or other debris from becoming tangled and/or trapped within the drain assembly 10.
