BACKGROUND
Hair can accumulate in drains, such as bathtub, shower, and sink drains. As hair accumulates, the flow of water through the drain decreases until the drain clogs and water can no longer flow through the drain. The accumulated hair must be physically removed by either disassembling the drain, running a rotary pipe-snake through the drain to clear the clog, or adding harsh chemicals into the drain in an attempt to dissolve the hair. Each of these processes risks damaging the drain itself or injuring the individual attempting to clear the drain.

DETAILED DESCRIPTION
FIG. 1A shows a perspective view of an external hair strainer 100. The external hair strainer 100 can be affixed to a drain stopper (e.g., a bathtub or kitchen drain stopper) in order to prevent hair from entering and accumulating in a drain. The external hair strainer 100 may be manufactured from any number of flexible materials, including various silicone compounds, rubber or synthetic rubber compounds, or other appropriate materials.
The external hair strainer 100 can include a rim 103 at the base of the external hair strainer 100, a button 106 at the top of the external hair strainer 100, a plurality of spokes 109 connecting the rim 103 to the button 106, a first bend 113, and a second bend 116. The rim 103 is positioned to form at least a partial seal with a surface, such as a bathtub surface or sink surface. The button 106 can be depressed to engage the external hair strainer 100 with a drain stopper, such as a stopper for a bath tub or sink. The rim 103 is located on a first plane, while the button 106 is located on a second plane parallel to the first plane. The rim 103 and the button 106 are both centered along the same axis of rotation 107 that runs perpendicular to the first plane and the second plane.
FIG. 1B shows another perspective view of the external hair strainer 100. As shown, a rim 103 at the base of the external hair strainer 100 is connected to the button 106 at the top of the external hair strainer 100 by a plurality of spokes 109. Each of the plurality of spokes 109 are tapered as they connect the inner diameter of the rim 103 of the external hair strainer 100 with the outer diameter of the button 106, thereby forming a collapsible skirt extending from the button 106 to the rim 103. The inner diameter of the rim 103 is greater than the outer diameter of the button 106 and each of the plurality of spokes 109 is narrower at a first connection with the button 106 and wider at a second connection with the rim 103. In some embodiments, the spokes 109 may be set at equidistant points along the rim 103 with respect to adjacent spokes 109. Each spoke 109 in the plurality of spokes 109 may be separated from other spokes 109 by gaps that allow water or other liquids to pass through the external hair strainer 100 while preventing hair or other objects from entering a drain.
A first bend 113 and second bend 116 on each spoke 109 prevent the external hair catcher 100 from returning to its original shape when the plurality of spokes 109 are flexed as a result of the button 106 being depressed. The first bend 113 and the second bend 113 may be placed one above the other at a point approximately half-way between the inner diameter of the rim 103 and the outer diameter of the button 106. For instance, the first bend 113 and the second bend 116 may be located on separate horizontal plans crossing through the spoke 109 and also located along the same line running perpendicularly through the separate horizontal planes. This arrangement increases the hoop strength of the external hair catcher 100 to prevent the external hair catcher 100 from inverting when the spokes 109 are flexed. Moreover, the first bend 113 of each spoke 109 may be located at the same position on each spoke 109, forming a first concentric circle between the rim 103 and the button 106. Likewise, the second bend 116 of each spoke 109 may be located at the same position on each spoke 109, forming a second concentric circle between the rim 103 and the button 106.
Any two spokes 109 may also be connected with a connector 119. The connector 119 helps to maintain the form of the external hair strainer 100 as it flexes between positions as may occur, for example, when the button 106 is depressed or raised. Although the connector 119 depicted in FIG. 1A is position between the second bend 116 and the button 106, the connector 119 may be placed in other locations as may be appropriate for particular embodiments of the present disclosure. For example, the connector 119 could be placed between the first bend 113 and the second bend 116.
FIG. 1C depicts a cross sectional view of the perspective view of FIG. 1B, illustrating a suction cup 123 of the external hair strainer 100. As shown, the suction cup 123 extends from a bottom surface of the button 106, placing the suction cup 123 within the collapsible skirt formed by the plurality of spokes 109. Moreover, the bottom of the suction cup 123, as illustrated, lies within a third plane positioned between, and parallel to, the first plane containing the rim 103 and the second plane containing the button 106. The suction cup 123 also includes an internal cavity 126 separated into a first chamber 129 and a second chamber 133 by a ridge 136. The internal cavity 126 allows for the suction cup 123 to generate suction when pressed against a surface. The first chamber 129 and the second chamber 133 allow for a knob or similar portion of a drain stopper to fit within the internal cavity 126 of the suction cup 123. The ridge 136 allows for the suction cup to grab know of the drain stopper, thereby attaching the suction cup 123 and the external hair strainer 100 to the knob of the drain stopper.
FIG. 2 represents a cross-sectional view illustrating the external hair strainer 100 positioned on top of a drain stopper 200 of a bathtub in accordance with various embodiments of the present disclosure. As shown, the drain stopper 200 extends into the internal cavity 126 of the suction cup 123. The knob 203 of the drain stopper 200 sits above the ridge 136 within the second chamber 133 of the internal cavity 126 of the suction cup 123. Likewise, the suction cup 123 forms at least a partial seal with the top surface 206 of the drain stopper 200, thereby attaching the external hair strainer 100 to the drain stopper 200. The spokes 109 can flex at the first bend 113 or the second bend 116 to allow the collapsible skirt formed by the plurality of spokes 109 to partially collapse, such that the rim 103 can remain substantially within the first plane and maintain contact with a surface surrounding the drain stopper 200 (e.g., a sink surface) as the button 106 is depressed.
FIG. 3 is a top-down perspective view illustrating the external hair strainer positioned on top of a drain stopper of a bathtub in accordance with various embodiments of the present disclosure.
While tub drains were described it should be noted that this hair catcher is not limited to tub drains as the same design can also be used in bathroom lavatory drains as well as kitchen sink drains or any other drain as appropriate.
