Description

FIELD OF THE INVENTION

The present disclosure relates to popup drain stoppers and, more particularly, to popup drain stoppers with debris traps and popup drain stopper assemblies having the same.

BACKGROUND OF THE INVENTION

Sinks, showers, and bathtubs contain a drainage outlet to permit the egress of water from the reservoir. The drainage outlet may be open or contain a drain protector to act as a sieve by removing debris from the flow of water before its entrance into the drain. Some drainage outlets are equipped with a pop-up plug allowing the user to selectively retain water in the reservoir before drainage.

Even with the use of a drain cover, drainpipes often become clogged due to the buildup of debris washed away by the flow of water. The leading cause of clogging is the accumulation of hair which slowly builds over time until the water no longer drains effectively. The inability of water to drain may result in unsanitary conditions and provides a medium for harboring bacteria and waterborne pathogens.

It can be undesirable to chemical-based drain cleaners due to their toxicity. The most common chemical is highly concentrated sulfuric acid which can dissolve cellulose, proteins, and fats. Such harsh chemicals are potentially dangerous if used improperly, and repeated use often results in damage to the drainpipes, leading to expensive repairs. Further, the chemicals found in drain cleaners may react with household products and cause explosive, or highly toxic reactants.

DETAILED DESCRIPTION

Embodiments of the invention provide a popup drain stopper with debris trap and popup drain assemblies having the same. As used herein, the term “debris” may refer to any object that may be transferred into a drain outlet and the drainpipe. By way of non-limiting example, the debris may include hair, hairpins, soaps and detergents, dust, dirt, cosmetic products, jewelry, or other small particles and objects.

Embodiments relate to a drain stopper configured to be at least partially inserted into a drain outlet. The drain stopper may be configured to be used in any plumbing fixture having a drain outlet including, but not limited to a floor drain, sink, bathtub, shower, lavatory, or similar drains wherein debris may cause a clog resulting in the inability to drain fluids. The drain stopper is comprised of a removable debris trap configured to filter and trap debris from obstructing the flow of water before the debris continues further into the drainpipe.

In FIG. 1, there is illustrated a popup drain stopper 10 in accordance with an embodiment of the invention. The stopper 10 is shown disposed in the interior of a conventional drainpipe 12 having a drain opening 14 through which the stopper is inserted for up and down movement within the interior of the drainpipe to selectively seal the drain opening.

The stopper 10 has an elongated stem 16 with opposite, upper and lower ends. A cap 19 is attached to the stem at its upper end. The cap 19 has a seal, such as, for example an O-ring 20. The cap 19 and seal 20 extend above the drain opening 14 when raised to an elevated position and closes and seals the drain opening when lowered into a sealing position by the seal making a sealing contact with the drainpipe. In the representatively illustrated embodiment, the lower end of the stem 16 has an aperture 22 which engages with a lever rod 24 of a conventional stopper actuating mechanism that is well known in the art and operates raise and lower the stopper for sealing and opening the draining opening 14. The lever rod 24 is connected to a captive ball 25, which allows the rod to be pivoted upward and downward to move the stopper.

With continued reference to FIG. 1 and further reference to FIGS. 2 and 3, the stem 16 has four, elongated, perpendicular ribs or fins 26 that extend along the length of the stem between its opposite ends. A row of bristles 28 is disposed along opposite broad surfaces of at least two fins 26 (one only visible in this figure) and extend outwardly therefrom in a direction that is generally perpendicular to the longitudinal length of the stem.

The bristles 28 provide a debris trap for trapping, collecting, or otherwise entangling debris that flows through the drain opening 14 and along the stopper 10. The debris being trapped by the bristles 28 is prevented from flowing through the drainpipe, thereby preventing clogging thereof. The stopper 10 can be removed from the drainpipe for clearing or cleaning the bristles of the debris.

While, in this representative embodiment, only a single row of bristles 28 is shown disposed on opposite surfaces of at least two fins 26, it should be understood the invention is not limited to this arrangement. Any number of rows, shape, size, or configuration of bristles may be disposed on the fins 26 for trapping, collecting, or otherwise entangling debris that flows through the drain opening could be used.

With additional reference to FIG. 4, there is shown an exploded view of stopper 10. The upper end of the stem 16 may have a threaded stud 32 and the lower end of cap 19 may have a corresponding threaded aperture 34 to threadedly attach the cap to the upper end of the stem. The cap 19 may further include a circumferential groove 36 for receiving and retaining the seal 20. As further shown, the upper end of the cap 19 has a generally flat, cylindrical shape.

Further shown is an alternative cap 30. Like cap 19, cap 30 includes a threaded aperture 34 for attaching the cap to the threaded stud 32 and includes a circumferential groove 36 for receiving and retaining the seal 20. The upper end of cap 30, however, is dome-shaped and includes a scallop-shaped circumferential edge 38. FIG. 5 illustrates at top-down view of cap 30.

In FIGS. 6 and 7, stopper 10 is shown with an alternative arrangement of bristles 28 on stem 16. Particularly, bristle rows 28 are disposed in the corners formed between two conjoining fins 26 and extend along the length of the fins and outwardly therefrom at generally 45 degrees relative to the corresponding fins.

In FIGS. 8 and 9 there is illustrated a popup drain stopper 100 in accordance with an embodiment of the invention. Stopper 100 has a construction like stopper 10 and, accordingly, like reference numbers refer to similar elements. Stopper 100 is configured to allow an easier coupling and decoupling with lever rod 24 without requiring a user to dissemble the stopper operating mechanism. Further, stopper 100 is configured to prevent an unknowledgeable user from inadvertently breaking the stopper or the lift mechanism when he or she attempts to forcefully withdraw the stopper from an associated drainpipe.

Particularly, as shown, a lower length of stem 102 of stopper 100 is bifurcated into a pair of coextending tangs 104 that are separated by a slot 106 extending from the lower end of the stem in a direction toward the stem's upper end. The slot 106 is configured to removably receive the lever rod 24 in a sliding engagement between the tangs 104 from the lower end of the stem. The slot 106 may have at least one, representatively shown three, apertures 108 spaced along the length of the slot. The apertures are configured to selectively retain the lever rod 24 at positions along the length of the slot. The width of the slot 106 narrows in a direction from the upper end toward the lower end of the stem 102 to provide a frictional engagement and retention force to the lever rod 24 against withdrawal from the slot once inserted therein.

The lower end of each tang 104 has a winglet 110 that extend in opposite directions of one another and provide a fishtail-shaped notch 112 therebetween at the lower of end of the stem 102. The fish-shaped notch 112 narrows in a direction from the lower end of the stopper toward the top end of the stopper. The winglets 110 combined with the fishtail-shaped notch 112 guide the lever rod 24 toward the open end of the slot 106. The interior surfaces of the winglets 110 contact the exterior surface of the lever rod 24 as the rod is advanced toward the slot opening which causes tangs 104 to flex outwardly from one another and open the narrow end of the slot for reception of the lever rod therein. The winglets 110 extend in the opposite directions by each having an outward surface that extends at an angle from the outward side of its respective tang 104 and terminate at a winglet tip that is disposed at an outward position relative to the outward side of the tang.

Further shown is another arrangement of the bristles 18. Particularly, the opposite surfaces of at least two fins 26 include two bristle rows 28, as opposed to a single row shown and described above.

FIGS. 10 and 11 illustrate stopper 100 with an alternative bristle arrangement. Particularly, the bristle rows 28 shown in the example comprise large bristles with large heads but a fewer number of bristles per row than the previously shown and described bristle rows. Further shown is an alternative cap 114 attached to stem 102. Cap 114, like the previously shown and described caps 19, 30, may include a threaded aperture 34 for removable attachment of the cap to the threaded stud 32 and includes a circumferential groove 36 for receiving and retaining the seal 20. Additionally, the upper end of the cap has an enlarged circular-shaped plate element 116.

FIGS. 12 and 13 illustrate stopper 100 without bristle rows 28 located on the stem 102 and with an alternative cap 118. Cap 119, like the previously described caps, may include a threaded aperture 34 for removably attachment to the threaded stud 32. With further reference to FIG. 14, cap 119 has a generally circular shaped body with a top side 120 and an opposite bottom side 122. Extending outwardly from the bottom side are a plurality of bristles 124. When the cap 119 is attached to the stem 102, the bristles 124 extend in a direction toward the bottom end of the stem and are arranged around the top of the stem. Like bristle rows 28, bristles 124 provide a debris trap for trapping, collecting, or otherwise entangling debris that flows through the drain opening 14. The debris being trapped by the bristles 124 is prevented from flowing through the drainpipe, thereby preventing clogging thereof.

FIGS. 15-17 illustrate a popup drain stopper 200 in accordance with an embodiment of the invention. Stopper 200 has a construction like stoppers 10, 100 and, accordingly, like reference numbers refer to similar elements. Stopper 200 is configured to allow for easier insertion and removal from the drainpipe 12 and is operatable without a stopper operating mechanism having a lever rod.

Particularly, as shown, a lower length of stem 202 of stopper 200 is generally planar shaped and has opposing broad flat faces providing at least one broad flat face that is configured to slide across a retaining magnet. A series of magnets 204 are spaced along the stem. The magnets 204 are configured to engage with a plug 206 that is attached to the drainpipe 24 and extends into the flow passage thereof. The plug 206 can have a ferrous material 208 to which the magnets 204 are magnetically attracted. Alternatively, the material 208 could be a retaining magnet that is arranged with its magnetic poles opposite of magnets 204 to cause an attractive, magnetic force therebetween. Also, the magnets 204 could be replaced with a ferrous material that is magnetically attracted to a magnet in the plug 206. The plug 206 has a fixed projection 209 that extends into the drainpipe 12 and the material or magnet 208 is disposed at the end of the fixed projection.

In operation, the position of the stopper 200 in the drainpipe 24 is selectively adjusted by simply pulling up or pushing down on the stopper. The stopper 200 will be held in selective positions by the magnetic force between one of the magnets 204 and the material/magnet 208. Additionally, the stopper 200 can be completely removed from the drainpipe 12 by simply pulling it upward and out of the drain opening 14.

Stopper 200 is further shown with cap 30 and bristle rows 18 located on opposite sides of at least two fins 26. Additionally, plug 206 can be configured to attach to the drainpipe 12 where the typical or conventional stopper operating mechanism, including the lever rod, is attached to the drainpipe.

FIGS. 19 and 20 illustrated a popup drain stopper 300 and operating mechanism 302 in accordance with an embodiment of the invention. Stopper 300 has a construction like stopper 10, 100, and 200 and, accordingly, like reference numbers refer to similar elements. Stopper 300 and operating mechanism 302 are configured to allow an easier coupling and decoupling without requiring a user to dissemble the operating mechanism. Further, the stopper 300 and operating mechanism 302 are configured to prevent an unknowledgeable user from inadvertently breaking the stopper or the lift mechanism when he or she attempts to forcefully withdraw the stopper from an associated drainpipe.

Particularly, as shown, the bottom 304 of the stopper stem 306 has a magnet 308 attached therewith. The bottom 304, together with the magnet 308, are configured to removably engage with an end 310 of a lever rod 312. The lever rod end 310 has a magnet or ferrous material 314 that is magnetically attracted to the magnet 308 on the stopper stem 306. According, the magnet 308 and magnet or ferrous material 314 provide a magnetic coupling between the stopper stem 306 and the lever rod 312. The magnet 308 could be exchanged with a ferrous material that would be magnetically attracted to the magnet 314 on the lever rod end 310.

Conventionally, lever rod 312 has a ball 314 that is captively held in a socket and that allows the rod to be moved upward and downward by a connecting rod that extends upwardly, such configuration is well known in the field. Stopper 300 is further shown with cap 119 and bristle rows 18 having the large head configuration located on opposite sides of at least two fins 26.

In FIGS. 21-24 there is illustrated a popup drain stopper 400 in accordance with an embodiment of the invention. Like drain stopper 100, stopper 400 is configured to allow an easier coupling and decoupling with lever rod 24 without requiring a user to dissemble the stopper operating mechanism. Further, stopper 400 is configured to prevent an unknowledgeable user from inadvertently breaking the stopper or the lift mechanism when he or she attempts to forcefully withdraw the stopper from an associated drainpipe.

Particularly, as shown, a lower length of stem 402 of stopper 100 is bifurcated into a pair of coextending tangs 404 that are separated by a slot 406 extending from the lower end of the stem in a direction toward the stem's upper end. The slot 406 is configured to removably receive the lever rod 24 in a sliding engagement between the tangs 404 from the lower end of the stem. The slot 406 may have at least one, representatively shown three, apertures 408 spaced along the length of the slot. The apertures are configured to selectively retain the lever rod 24 at positions along the length of the slot. The width of the slot 406 narrows in a direction from the upper end toward the lower end of the stem 402 to provide a frictional engagement and retention force to the lever rod 24 against withdrawal from the slot once inserted therein.

The lower end of each tang 404 has a winglet 410 that extend in opposite directions of one another and provide a fishtail-shaped notch 412 therebetween at the lower of end of the stem 102. The fish-shaped notch 412 narrows in a direction from the lower end of the stopper toward the top end of the stopper. The winglets 410 combined with the fishtail-shaped notch 412 guide the lever rod 24 toward the open end of the slot 406. The interior surfaces of the winglets 410 contact the exterior surface of the lever rod 24 as the rod is advanced toward the slot opening which causes tangs 404 to flex outwardly from one another and open the narrow end of the slot for reception of the lever rod therein.

Stopper 400 further includes a cylindrically shaped bristle body 414 having a plurality of bristles 416 arranged in a plurality of rows such that the bristles are arranged around the entire body and radially project outwardly therefrom. The body 414 is removably attached to the stem 402 at the body's bottom end 418 by a threaded coupling having a threaded post 420 on the stem and a cooperating threaded bore 422 formed through the bottom of the body.

A cap, such as cap 114 is removably attached to the top end 424 of the body 414 by a threaded coupling having a threaded post 426 on the top end of the body 414 and a cooperating threaded bore 34 in a bottom of the cap. As described previously, cap 114 can have an O-ring 20 for sealing with a drain opening.

As further shown in FIG. 22, a cap 428 that is like cap 30 can be provided for attachment to body 414. Cap 428 is umbrella shaped like cap 30 but does not include an O-ring seal like cap 30. A cap 430 can also be provided for attachment to body 414. Cap 430 has a disk-shaped top 432 with a knob 434 extending upwardly from the cap. The knob 434 is configured to be grasped by a user to move the stopper 400 inwardly and outwardly from a drain opening. The cap 430 includes a threaded bore 436 on a bottom end for threaded coupling with post 426 on body 414.

The construction of stopper 400 allows disassembly thereof for easy cleaning of the bristles 416 from captured debris like hair and/or replacement of the bristle body without requiring replacement of the entire stopper assembly.

While not shown, stem 402 of stopper 400 could be configured to be any of the stems that are have been described herein. For example, stem 402 could be configured with like stem 202 of stopper 200 to include the magnet 204 configuration.
