Abstract

Disclosed are various embodiments of an external hair strainer. The external hair strainer can have a number of components. For example, the external hair strainer can include a rim positioned on a first plane. The external hair strainer can also include a button positioned on a second plane parallel to the first plane. In some instances, the external hair strainer can include a suction cup protruding from the button in the direction of the rim. Moreover, the external hair strainer can have a plurality of spokes connecting an inner diameter of the rim to an outer diameter of the button, each of the plurality of spokes comprising a bend.

Claims (40)

1. An apparatus, comprising:

a rim positioned on a first plane;

a button positioned on a second plane parallel to the first plane;

a suction cup protruding from the button in a direction of the rim; and

a collapsible skirt formed by a plurality of spokes connecting an inner diameter of the rim to an outer diameter of the button, each of the plurality of spokes comprising a first bend and a second bend, wherein the first bend and the second bend are curved inward toward an interior of the collapsible skirt, wherein the plurality of spokes have an inclined surface between the first bend and the second bend, wherein the first bend and the second bend of the plurality of spokes enable the collapsible skirt to maintain a collapsed state toward a drain when the suction cup is attached to a drain stopper from the drain and the drain stopper is in a closed position in a sink.

2. The apparatus of claim 1 , wherein the plurality of spokes connect to the inner diameter of the rim at equidistant points.

3. The apparatus of claim 1 , wherein the plurality of spokes connect to the outer diameter of the button at equidistant points.

4. The apparatus of claim 1 , wherein the first bend and the second bend of the plurality of spokes are located at the same position on each of the respective ones of the plurality of spokes to form a concentric circle between the rim and the button.

5. The apparatus of claim 1 , wherein the rim, the button, and the plurality of spokes are manufactured from a flexible material.

6. The apparatus of claim 1 , wherein the rim and the button are centered on an axis of rotation perpendicular to the first plane and the second plane.

7. The apparatus of claim 1 , wherein each of the plurality of spokes are tapered, wherein each of the plurality of spokes are narrower at a first connection with the button and wider at a second connection with the rim.

8. A device, comprising:

a rim positioned on a first plane;

a button positioned on a second plane parallel to the first plane;

a suction cup protruding from the button in a direction of the rim; and

a collapsible skirt formed by a plurality of spokes connecting an inner diameter of the rim to an outer diameter of the button, each of the plurality of spokes comprising:

a first bend located at the same first position on each of the respective ones of the plurality of spokes to form a first concentric circle between the rim and the button;

a second bend located at the same second position on each of the respective ones of the plurality of spokes to form a second concentric circle between the rim and the button;

a third bend located at the same third position on each of the respective ones of the plurality of spokes to form a third concentric circle between the rim and the button; and

wherein the first bend and the second bend are curved inward toward an interior of the collapsible skirt, wherein the plurality of spokes have an inclined surface between the first bend and the second bend, wherein the collapsible skirt is configured to collapse toward a drain when the suction cup is attached to a drain stopper from the drain and the drain stopper is moved from an open position to a closed position in a sink.

9. The device of claim 8 , wherein the first bend and the second bend of each one of the plurality of spokes are located on separate parallel horizontal planes crossing through the spoke and along a line running perpendicularly through the separate parallel horizontal planes, the line being located at a point approximately half-way between the inner diameter of the rim and the outer diameter of the button.

10. The device of claim 8 , wherein the second bend and the third bend of each one of the plurality of spokes are located on separate parallel horizontal planes crossing through the spoke and along a line running perpendicularly through the separate parallel horizontal planes, the line being located at a point approximately half-way between the inner diameter of the rim and the outer diameter of the button.

11. The device of claim 8 , wherein the plurality of spokes connect to the inner diameter of the button at equidistant points.

12. The device of claim 8 , wherein the plurality of spokes connect to the outer diameter of the rim at equidistant points.

13. The device of claim 8 , wherein the rim and the button are centered on an axis of rotation perpendicular to the first plane and the second plane.

14. The device of claim 13 , wherein the suction cup is centered on the axis of rotation perpendicular to the first plane and the second plane.

15. The device of claim 8 , wherein each of the plurality of spokes are tapered and each of the plurality of spokes are narrower at a first connection with the button and wider at a second connection with the rim.

16. An apparatus, comprising:

a rim positioned on a first plane;

a button positioned on a second plane parallel to the first plane;

a suction cup protruding from the button in the direction of the rim; and

a collapsible skirt formed by a plurality of spokes connecting an inner diameter of the rim to an outer diameter of the button, each of the plurality of spokes comprising:

a first bend located at the same first position on each of the respective ones of the plurality of spokes to form a first concentric circle between the rim and the button;

a second bend located at the same second position on each of the respective ones of the plurality of spokes to form a second concentric circle between the rim and the button; and

a third bend located at the same third position on each of the respective ones of the plurality of spokes to form a third concentric circle between the rim and the button; and

wherein the second bend and the third bend of each one of the plurality of spokes are located on separate parallel horizontal planes crossing through the spoke and along a line running perpendicularly through the separate parallel horizontal planes, the line being located at a point approximately half-way between the inner diameter of the rim and the outer diameter of the button.

17. The apparatus of claim 16 , wherein the rim, the button, and the suction cup are centered on an axis of rotation perpendicular to the first plane and the second plane.

18. The apparatus of claim 16 , wherein the plurality of spokes connect to the inner diameter of the button at equidistant points and connect to the outer diameter of the rim at equidistant points.

19. The apparatus of claim 16 , wherein each of the plurality of spokes are tapered and each of the plurality of spokes are narrower at a first connection with the button and wider at a second connection with the rim.

20. The device of claim 8 , wherein the third bend is curved away from the interior of the collapsible skirt.
