FIELDThe present invention pertains to the field of plumbing and more specifically to an apparatus for preventing plugs, clogs or backups caused by debris and foreign matter accumulating in shower, tub or sink drains.
BACKGROUNDIf a sink, shower stall or tub will not drain, or if the water drains too slowly, more than likely there is a clog somewhere within the drain. Once this stage is reached, Black & Decker, The Complete Guide to Home Plumbing, © 2005, the current state-of-the-art, teaches that the options to remove the clog are either to use a plunger, hand auger, blow bag or chemical drain cleaner. A plunger is usually the tool of first choice, but the clog may be too large or positioned too deeply within the drain to enable the clog to be broken via the plunger. The next choice is typically the hand auger, but this device requires some expertise on the part of the user to differentiate between a clog and a bend in a drain line. Blow bags are fairly easy to use, but they are typically used only for floor drains (e.g. drains located in basement floors). Chemical drain cleaners are effective but run the risk of damaging the plumbing lines because of the caustic chemicals that make up the formulation.
Since unclogging a drain can be difficult it is preferable to prevent the clog with a debris entrapment device or apparatus. A strainer is one type of debris entrapment apparatus. Strainers are designed to catch debris before it enters into the drain. This unsightly, unhygienic approach means that the user must constantly see the debris that has accumulated in the sink, shower stall or tub and then physically remove the debris from the strainer by hand. Strainers also have an additional problem in that they may develop leaks from improper positioning within the drain assembly or deterioration of the plumbers putty. In such circumstances, the leak must be pinpointed and remedied by either removing the strainer, reapplying plumbers putty then reinserting or replacing the strainer with a new strainer.
Previous debris catching apparatii suffered from debris build up and a resultant inability for water to pass through the apparatus. These deficiencies resulted in clogged drains, unsanitary conditions, and time consuming remedies with no economical, convenient, preventative option for the consumer to prevent such clogs or back-ups. For example, U.S. Pat. No. 3,959,831 describes another debris entrapment apparatus inserted into the drain, with the apparatus having bristles radiating from a center member to the outer wall of the drain.
As noted in U.S. Pat. No. 5,003,642 the debris entrapment apparatus of U.S. Pat. No. 3,959,831 eventually suffer from problems with water back up. Furthermore, if debris is entrapped in the apparatus, it is difficult to remove the hair or other foreign matter.
There exists therefore a need for an apparatus that entraps foreign matter and debris and allows water passage through the device, but at the same time, designed to be easy to use by any homeowner, plumber, maintenance person or any other individual charged with cleaning or upkeep of a drain.

The bristle holding device of this embodiment may be a vertical longitudinal member of any circumferential arrangement including but not limited to round, square or rectangular configurations. The bristle holding device may be made of any material, including but not limited to, plastics, metals, composites or combinations thereof. The plurality of bristles are said to radiate, or spread out, or spread around, or project from the bristle holding device. By configuring the bristles on the bristle holding device in this manner, hair and other foreign matter accumulates in the bristles radiating from the bristle holding device. The bristle arrangement in the present embodiment ensures that water continues to pass through, even if debris were to accumulate within the bristles. The only other limitation on the placement of the bristles is to have the bristles radiate from the bristle holding device in any direction but parallel to the length direction of the bristle holding device and to have the bristles affix to the bristle holding device at at least one end of the bristles.

The debris entrapment apparatus may be constructed of any suitable material, including but not limited to, plastic and metals.
In accordance with another embodiment of the invention,
The term bristles in the current embodiment includes any foreign matter catching member, including but not limited to, bristles, spikes, filaments, spicules, and rod-like elements—whether round, square or otherwise in cross sectional configuration. The pliability of the bristles vary from flexible to stiff and anything in between. If a bristle can bend when touched by a finger it is considered flexible, if the bristle does not bend when touched by a finger, it is considered stiff. The length of the bristles ranges from short, extending just past the bristle holding inner core to long, extending and possibly touching the side of the drain wall. The outside diameter of a drain pipe is typically from 1¼″ to 1½″. The inside diameter of the same drain pipe, i.e. the drain wall, is typically 1⅛″ to 1⅜″. Therefore, the lengths of the bristles are equal to or less than the diameter of the perimeter created by the inside of the drain wall. The perimeter created by the inside of the drain wall being a circle, oval or other non-circle arrangement. The arrangement of the bristles on the bristle holding inner core may be in any configuration, including but not limited to, bristles closely spaced and adjacent to one another, to more open arrangements where the bristles are spaced farther apart from one another. The bristles may be arranged in a plurality of layers across the entire circumference of the bristle holding inner core, for example such that one layer of bristles is directly on top of another layer of bristles or the arrangement may be one in which one layer of bristles is never on top of another layer of bristles. The bristles may be made of any material including but not limited to plastics, metals, composites, or combinations thereof. The bristles may be in a straight line or any curved configuration. There also may be secondary bristles, or branches, attached to the trunk or main bristle.
