Construction

(29) The present described invention is a drain plug kit 10 with a buoyant drain plug pull cord. One embodiment of the kit 10 contains a buoyant member 20, a drain plug 30, and a biasing member 40. A second embodiment of the kit 10 contains a buoyant member 20, a biasing member 40 and an adapter member 50.

First Embodiment

(30) Referring to FIGS. 1-3, the drain plug 30 has a first surface 30.sub.1 and a second surface 30.sub.2 and is configured and arranged to open and close a drain hole in a sink, tub or other liquid holding vessel (not shown). The first surface 30.sub.1 is the surface visible when the drain plug 30 is inserted into a drain hole to close the drain. A stem 33 may laterally Y project from the first surface 30.sub.1. Preferably the stem 33 is longitudinally X and transversely Z centered on the first surface 30.sub.1.

(31) The drain plug 30 has an attachment means 60 on the first surface 30.sub.1. Preferably the attachment means 60 is at least one retention clip 32. Most preferably there are two retention clips 32 longitudinally X or transversely Z spaced on either side (not numbered) of the stem 33. Any suitable type of retention clip 32 may be used such as an open clip or a closable clip.

(32) Referring to FIGS. 23-26, a second embodiment of the drain plug 30 has a first surface 30.sub.1 and a second surface 30.sub.2 and is configured and arranged to open and close a drain hole in a sink, tub or other liquid holding vessel (not shown). The first surface 30.sub.1 is the surface visible when the drain plug 30 is inserted into a drain hole to close the drain. A suction cup 34 may laterally Y project from the second surface 30.sub.2 for use in releasably securing the drain plug 30 to a nonporous vertical surface, such as the sidewall of a sink, when not in use.

(33) The buoyant member 20 may be any suitable buoyant object that is configured and arranged to float on water (not shown) if untethered from the drain plug 30. But, the buoyant member 20 is configured and arranged to be ineffective for automatically seating or unseating the drain plug 30 from a drain hole when tethered to the drain plug 30. The buoyant member 20 may be made of any suitable material such as foam, sponge, Styrofoam, wood, or a gas filled member. The preferred materials are foam or sponge. The buoyant member 20 may be any desired shape or size. Preferably the size is relatively small in relation to the surface area of the water in the vessel to reduce the likelihood of the buoyant member 20 interfering with the use of the water to wash dishes or being inadvertently pulled out of the water yet large enough to allow easy gripping when needed to remove the buoyant member 20 from the water. Examples of shapes are shown in FIGS. 4 and 18. The buoyant member 20 may also have indicia 22 on at least one surface 21 as shown in FIG. 18 to advertise a company's products or services or to enhance the appearance of the drain plug kit 10. The buoyant member 20 may also have a scouring pad 23 attached to at least one surface 21 as shown in FIG. 22. The scouring pad 23 may then be used to clean items.

(34) More than one buoyant member 20 may be tethered to the drain plug 30. For example, a first buoyant member 20 as shown in FIG. 14 may be tethered to the drain plug 30 and then a second buoyant member 20 made of a sponge and having a scouring pad 23 attached to at least one surface 21 also tethered to the drain plug 30 or the first buoyant member 20.

(35) A biasing member 40 tethers the buoyant member 20 to the drain plug 30. As shown in FIGS. 5 and 23-25, the biasing member 40 has a first end 41 and a second end 42. Preferably, the biasing member 40 is biased toward a collapsed position as shown in FIGS. 5-7 and 23-25. The biasing member 40 may be any suitable biasing member 40 that is biased into a collapsed position such as a spring or a retractable cord. The biasing member 40 may be made from any suitable material such as metal or plastic. The biasing member needs a biasing force strong enough to return to a collapsed position outside of a liquid but not strong enough to overcome the buoyancy of the tethered buoyant member. The preferred biasing member 40 is a helical spring. The helical spring is not only biased in a collapsed position but is biased about a lateral axis Y1 while in the collapsed and extended positions as shown in FIGS. 6, 8, and 9. As shown in FIGS. 13 and 14 the lateral bias may help keep the buoyant member 20 centered over the lateral axis Y1 of the biasing member 40 to reduce the chances of the buoyant member 20 interfering with the use of the water in the vessel.

(36) The first end 41 of the biasing member 40 is configured and arranged to attach to the buoyant member 20. The first end 41 may be integrally formed with the buoyant member 20, fixedly attached, or removably attached. Removable attachment is preferred. The removable attachment means 60 may be any suitable fastener such as a snap fastener, clip, clasp, retaining ring, threaded fastener or any other similar fastener. As shown in FIGS. 16, 17, 19 and 20, the snap fastener is preferred.

(37) The second end 42 of the biasing member 40 is configured and arranged to attach to the first surface 30.sub.1 of the drain plug 30. The second end 42 may be integrally formed with, fixedly attached to, or removably attached to the first surface 30.sub.1 of the drain plug 30. As shown in FIGS. 13 and 14 the preferred biasing member 40 second end 42 is removably attached to the drain plug 30. Any suitable attachment means 60 can be used to attach the biasing member 40 to the drain plug 30. The preferred removable attachment means 60 is a retention clip 32. As shown in FIGS. 1-3 and 23-25 the drain plug 30 may have one or more retention clips 32 on the first surface 30.sub.1 to removably engage the second end 42 of the biasing member 40.

(38) The biasing member 40 is configured and arranged to expand into an extended position when the second end 42 attached to the drain plug 30 is secured in a drain hole and the first end 41 is attached to the buoyant member 20 floating toward the surface of water in the sink, tub, or other vessel of water.

Second Embodiment

(39) If the biasing member 40 and buoyant member 20 are to be attached to an existing drain plug 30 not having a retention clip 32 or other attachment means 60 for the biasing member 40 then an adapter member 50 may be used to provide an attachment means 60 for the second end 42 of the biasing member 40. The adapter member 50 is configured and arranged to attach to the drain plug 30. Preferably the adapter member 50 is configured and arranged to attach to the stem 33 of the drain plug 30. As shown in FIG. 15 a first embodiment of the adapter member 50 has an open retention clip 51 configured and arranged to fit around the stem 33 on one end (not numbered) and a closed retention clip 51 on the other end configured and arranged to attach to the second end 42 of the biasing member 40. The biasing member 40 may also have a complementary retention clip 51 attached to or integrally formed in the second end 42.

(40) A second embodiment of the adapter member is shown in FIGS. 10, 11, 12, and 21. The adapter member 50 is longitudinally X elongated with an aperture 53 extending laterally Y through the member 50 and configured and arranged to accommodate the passage of the stem 33 of the drain plug 30. Adapter members 50 may be provided with different sized apertures 53 to accommodate different sized drain plug stems 33. Preferably the aperture 53 is centered longitudinally X and laterally Y on the adapter member 50. At least two flexible locking tabs 52 extend radially into the aperture 53 about a lateral axis Y2 to provide a snap fit connection between the adapter member 50 and the stem 33. The adapter member 50 has two retention clips 51 formed in the surface 54 of the member 50 configured and arranged to releasably engage the second end 42 of the biasing member 40.

(41) Use

(42) The drain plug kit 10 may be used in a sink, tub, or other liquid containing vessel with a drain hole. The kit 10 contains at least a buoyant member 20, a biasing member 40, and a drain plug 30 or an adapter member 50. Preferably the kit 10 contains all four pieces.

First Kit Embodiment

(43) A kit 10 having a buoyant member 20, a drain plug 30, and a biasing member 40 is obtained. As shown in FIG. 1, the drain plug 30 has at least one retention clip 32. The second end 42 of the biasing member 40 is attached to the drain plug 30 by the retention clip 32. Preferably the drain plug 30 has two retention clips 32 to attach the biasing member 40 to the drain plug 30 in two places to center the biasing member 40 over the drain plug 30 as shown in FIGS. 13 and 14. The first end 41 of the biasing member 40 is then attached to the buoyant member 20. The drain plug 30 is inserted into a drain hole of a vessel sealing the drain hole. As water is poured into the vessel the buoyant member 20 floats toward the surface of the water and pulls the biasing member 40 into an expanded position centered over the drain plug 30 as shown in FIG. 14. The buoyant member 20 floats toward the surface of the water until it rests on the top of the water or until the biasing member is fully extended. Once the water is no longer needed in the vessel the buoyant member 20 and biasing member 40 may be used as a pull cord to remove the drain plug 30 from the drain hole without touching the drain plug 30.

Second Kit Embodiment

(44) A kit 10 having at least a buoyant member 20, a biasing member 40, and an adapter member 50 is obtained. The adapter member 50 is attached to the stem 33 of a drain plug 30. Any drain plug 30 with a stem may be used such as a strainer drain plug 30 or a disposal stopper. The second end 42 of the biasing member 40 is attached to the adapter member 50. The first end 41 of the biasing member 40 is attached to the buoyant member 20. If a helical spring is used for the biasing member 40, the lateral axis Y1 of the biasing member 40 laterally Y overlaps the lateral axis Y2 of the adapter member 50. This centers the biasing member 40 and the buoyant member 20 over the drain plug 30 in the collapsed position and the expanded position. The drain plug 30 is then inserted into a drain hole of a vessel sealing the drain hole.
