(17) Adverting to the figures, FIG. 1 shows a perspective view of drain cover 100 positioned in bathtub 1 according to an example embodiment.

(18) FIG. 2A is a perspective view of drain cover 100 shown in FIG. 1.

(19) FIG. 2B is an exploded view of drain cover 100 shown in FIG. 2A.

(20) FIG. 3A is an elevational view of drain cover 100 shown in FIG. 2A.

(21) FIG. 3B is an exploded view of drain cover 100 shown in FIG. 3A. The following should be viewed in light of FIGS. 1 through 3B. Drain cover 100 broadly includes positioning member 101 and resilient sealing member 102. Positioning member 101 is arranged to surround an opening of a pipe of a drain and fit within the opening of the pipe. Openings 103 are arranged in positioning member 101. Resilient sealing member 102 is connected to positioning member 101 at center point P. Resilient sealing member 102 includes rim 104 arranged concentrically about center point P. Resilient sealing member 102 is arranged to plug the drain in a closed position relative to positioning member 101 and allow the passage of water yet prevent the passage of other materials, for example, hair, from clogging the drain in an open position relative to positioning member 101.

(22) In a closed configuration as shown in FIGS. 1 through 3B, resilient sealing member 102 includes rim 104 in contact with positioning member 101 to prevent fluid from passing through openings 103. In an open configuration (shown in FIGS. 7, 8, and 9) rim 104 does not contact positioning member 101 and fluid is allowed to pass through openings 103. Drain cover 100 is either in an open position or a closed position. Resilient sealing member 102 is flexible between the open and closed positions as discussed further below.

(23) Openings 103 are arranged in dome-shaped portion 105 of positioning member 101. Dome-shaped portion 105 includes solid portion 106 which provides a seat upon which resilient sealing member 102 can rest. In an example embodiment, solid portion 106 is planar. In an example embodiment, solid portion 106 includes a curvature which matches the curvature of the underside surface of resilient sealing member 102.

(24) Fastener 107 is provided to secure resilient sealing member 102 with dome-shaped portion 105 of positioning member 101. In an example embodiment, fastener 107 is intended to remain fastened at all times after manufacturing. Fastener 107 can be a rivet or any suitable alternative. In an example embodiment, fastener 107 can be removed by the user so that resilient sealing member 102 is removable from positioning member 101.

(25) Positioning member 101 includes cylindrical portion 108, arranged to fit within a pipe, and annular member 109. Cylindrical portion 108 extends downwardly from annular portion 109. Angle X is formed between cylindrical portion 108 and annular portion 109. In an example embodiment, angle X is 90 degrees. In an example embodiment, angle X is larger than 90 degrees.

(26) Dome-shaped portion 105 is taller than annular portion 109. The outer diameter of rim 104 is larger than the outer diameter of dome-shaped portion 105. In an example embodiment, openings 103 are smaller circumferentially proximate solid portion 106 and larger circumferentially proximate annular portion 109. Openings 103 form a point proximate solid portion 106. Each opening 103 is equidistant from the next adjacent opening 103 in a circumferential direction about center point P. Although a particular number and arrangement of openings is illustrated, drain cover 100 is not so limited. For example, openings 103 can be arranged at angles at 90, 180, 270, and 360 degrees. Alternatively, a plurality of openings can be arranged about half of dome-shaped portion 105 and the rest of dome-shaped portion 105 can be solid, or, formed including a single opening.

(27) FIG. 4A is a top view of drain cover 100 shown in FIG. 1, in a closed configuration. Annular portion 109, resilient sealing member 102, and fastener 107 are concentric. Rim 104 is not visible because it is contacting annular portion 109. In the example embodiment shown, resilient sealing member 102 and fastener 107 are annular like annular portion 109. However, other shapes are contemplated. Resilient sealing member 102 is arcuate from fastener 107 to rim 104.

(28) FIG. 4B is a top view of drain cover 100 shown in FIG. 1, in an open configuration. Annular portion 109, resilient sealing member 102, and fastener 107 are concentric. Rim 104 is visible. In an example embodiment, rim 104 is not visible in an open configuration and, instead, is visible from a side view only.

(29) FIG. 5 is a bottom view of drain cover 100 shown in FIG. 1. A planar circumferential surface extends inward from the outer diameter of annular member 109 toward cylindrical member 108. An arcuate circumferential surface extends from cylindrical member 108 to the planar surface. In an example embodiment, the arcuate circumferential surface is recess 110. In FIG. 5, the planar circumferential surface surrounds recess 110. The planar circumferential surface and recess 110 are concentric with cylindrical member 108. The bottom surfaces of drain cover 100 maximize water pressure when in use to provide a seal with the surface surrounding the drain whether the surface is flat or curved.

(30) FIG. 6 is a cross-sectional view of drain cover 100, taken generally along line 6-6 in FIG. 4A.

(31) FIG. 7 is a cross-sectional view of drain cover 100, taken generally along line 7-7 in FIG. 4B. The following should be viewed in light of FIGS. 6 and 7. In the closed configuration illustrated in FIG. 6, resilient sealing member 102 covers openings 103 in dome-shaped portion 105. In the closed configuration, resilient sealing member 102 forms a first angle relative to positioning member 101. In the open configuration illustrated in FIG. 7, resilient sealing member 102 does not cover openings 103 in dome-shaped portion 105. In the open configuration, resilient sealing member 102 forms a second angle relative to positioning member 101 where the second angle is larger than the first angle. To transition from the closed configuration to the open configuration, a user presses downwardly on top of fastener 107 in the direction shown. As fastener 107 is depressed downwardly, dome-shaped portion 105 is also depressed downwardly. Once fastener is fully pressed, rim 104 is urged upwardly and resilient sealing member 102 is urged into the open configuration.

(32) In the open configuration, rim 104 can be facing upwardly in the direction shown in FIG. 7 or outwardly. In the open configuration when rim 104 is arranged to face outwardly toward the sides of the page, resilient sealing member 102 is s-shaped.

(33) In the open configuration, drain cover 100 can be removed from a drain using resilient sealing member 102 which is extending upwardly. For example, a user can grab resilient sealing member 102 when it is extending upwardly in the open configuration and pull upwardly and drain cover 100 is lifted up and out of the drain. When drain cover 100 is not in place in a drain it can be easily stored, cleaned, or replaced.

(34) To transition from the open configuration to the closed configuration, a user can press downwardly on rim 104 or the outer edge of resilient sealing member 102 to contact annular member 109. As rim 104 is urged downwardly, fastener 107 and dome-shaped portion 105 remain upright.

(35) In an example embodiment, drain cover 100 is approximately 4 inches in diameter and approximately 1 inch tall from the bottom edge of cylindrical portion 108 to the top of fastener 107 in the closed position. In an open position, drain cover 100 is approximately 1.4 inches tall. In an example embodiment, resilient sealing member 102 is approximately 2 inches in diameter in the closed and open configurations. In an example embodiment, dome-shaped portion 105 is approximately 1.5 inches. In an example embodiment, drain cover 100 is 441 in (10.210.22.5 cm).

(36) Drain cover 100 can be made of silicone or any other suitable soft and flexible materials, for example, rubber. Fastener 107 is made of a light, rigid metal, for example stainless steel.

(37) FIG. 8 is an elevational view of an alternate embodiment of the drain cover shown in FIG. 1, in an open configuration. The discussion pertaining to drain cover 100 applies to drain cover 200 except as noted here. Drain cover 200 includes openings 203 in dome-shaped portion 205. Openings 203 are circular in an example embodiment. In an example embodiment, drain cover 200 includes two rows of openings 203. In an example embodiment, a first row of openings 203 is positioned circumferentially and radially half way between fastener 207 and annular member 109. In an example embodiment, in addition to the first row of openings, a second row of openings is arranged between the first row and fastener 207. In an example embodiment, openings 203 are arranged equidistant circumferentially. Drain cover 200 is not limited to the number and arrangement of openings 203 illustrated. For example, additional or fewer openings are contemplated and larger or smaller openings are contemplated as well. Additionally, the shape of the openings can vary.

(38) FIG. 9 is an elevational view of an alternate embodiment of the drain cover shown in FIG. 1, in an open configuration. The discussions pertaining to drain covers 100, 200 apply to drain cover 300 except as noted here. Drain cover 300 includes openings 303 in dome-shaped portion 305. Like openings 103, openings 303 are smaller circumferentially proximate fastener 307 as compared with the parts of openings 303 proximate annular member 309. Unlike openings 103 which form a point proximate fastener 107, openings 303 include a planar edge proximate fastener 307 and another planar edge proximate annular member 309.

(39) Thus, it is seen that the objects of the present invention are efficiently obtained, although modifications and changes to the invention should be readily apparent to those having ordinary skill in the art, which modifications are intended to be within the spirit and scope of the invention as claimed. It also is understood that the foregoing description is illustrative of the present invention and should not be considered as limiting. Therefore, other embodiments of the present invention are possible without departing from the spirit and scope of the present invention.
