The present invention is directed towards a device for a toilet bowl, more specifically towards a trapping device for catching and retaining non-dispersing cloths in the toilet bowl.
Manufacturers produce disposable cloths used for personal cleaning, bathing, incontinence care, and disinfection. These cloths differ from other disposable hygiene products (such as toilet paper) in that they do not break down and disperse when in contact with water.
These non-dispersible cloths may be used in an environment where they are disposed of into a toilet. An accumulation of these cloths flushed down a toilet drain may eventually lead to a back up in the toilet, blockage of the wastewater drain system, malfunction of sewage pumps, accumulation in municipal sewers and wastewater treatment plants, or bursting of sewage pipes.
The following presents a general summary of aspects of the invention in order to provide a basic understanding of at least some of its aspects. This summary is not intended as an extensive overview of the invention. It is not intended to identify key or critical elements of the invention or to delineate the scope of the invention.

As illustrated in
The strap 20 may be made of different materials without departing from the scope of the present invention. The strap material should allow the strap 20 to be able to fit within the various shapes of toilet bowls 14, yet also not fold or bend easily so that the strap 20 falls out of the trapway 12 of the toilet bowl 14. The strap 20 may be made of plastic, such as high density polyethylene (HDPE) to provide both strength and flexibility. Through testing by the inventor hereof, it has been found that using HDPE with a thickness between approximately 25-35 mil (0.025-0.035″ thick) provides enough thickness to ensure that the trapping device 10 does not fold or bend easily, while also making the trapping device 10 thin enough to fit well within the majority of toilet bowl 14 configurations. In another exemplary embodiment, the strap may be approximately 30 mil HDPE. Alternatively, the strap 20 may be made of metal. While the strap 20 may be made of metal, some metals will corrode and rust when placed in a wet environment. The strap 20 may be made of a stainless steel that is non-corrosive in accordance with at least some examples of this invention.
The adjustment buckle 40 may be attached to the first end 22 of the strap 20 as will be discussed further below. Additionally, the first end 22 of the strap 20 includes a single hole 32. On the second end of the strap, there may be a plurality of adjustment holes 34. The cooperation of the adjustment buckle 40, the adjustment holes 34, and an adjustment connector 52 at the single hole 32 provides the user with the ability to adjust the diameter of the strap 20 to fit various sized toilet bowls 14, making the trapping device 10 adjustable and universal to various toilet bowls 14.
The middle portion 26 may also include a polymer band or strip 36 located along the leading edge 28 of one side, the under-side, of the middle portion 26. The band 36 may be made of a polymer substance or polymer bead, such as a hot-melt glue (e.g., 3M Jet melt adhesive, part#3764-AE). The band 36 may be in the shape of a narrow strip which extends along the leading edge 28 of the middle portion 26. The band 36 creates a seal between the trapping device 10 and the bottom of the toilet bowl 14, which diverts the water flow above and through the trapping device 10 rather than beneath the trapping device 10. The band 36 may be made of any similar substance or similar shape in accordance with examples of this invention as long as it diverts the water flow above and through the trapping device 10 rather than beneath the trapping device 10.
The adjustment buckle 40 may be attached to the first end 22 of the strap 20 by an epoxy or glue material bonding the strap 20 to the adjustment buckle 40. The adjustment buckle 40 may include a set of front guides 42, a front tab 44, an alignment hole 46 and an adjustment connector 52. The set of front guides 42 are located on the front side of the adjustment buckle 40 and may include one or more guides. The set of front guides 42 are bent 180 degrees from the adjustment buckle 40, thereby creating a slot 50 between the strap 20 and the adjustment buckle 40. When the adjustment buckle 40 is connected to the strap 20, the set of front guides 42 may be positioned such that the second end 24 of the strap 20 can slide through the slot 50. Additionally, the set of front guides 42 are sized such that the hooks 60 do not interfere with the adjustment buckle 40 when sliding the second end 24 of the strap 20 through the adjustment buckle 40 and while the hooks 60 are in an adjacent lateral position with the adjustment buckle 40. The front tab 44 may be located on the front side of the adjustment buckle 40 and may protrude from the adjustment buckle 40 perpendicularly. The alignment hole 46 is located on the adjustment buckle 40 on the side opposite the front tab 44. When the adjustment buckle 40 is installed on the strap 20, the alignment hole 46 lines up with one of the adjustment holes 34 on the second end 24 of the strap 20 to receive the adjustment connector 52. The adjustment connector 52 may be inserted through the alignment hole 46 on the adjustment buckle 40, one of the adjustment holes 34 on the second end 24 of the strap 20, and the single hole 32 on the first end 22 of the strap 20 when the first end 22 of the strap 20 is inserted into the adjustment buckle 40. The adjustment connector 52 may hold the adjusted size of the trapping device 10 in place. The adjustment connector 52 may be in the form of a rivet, a screw, or other connector in accordance with at least some examples of this invention.
The adjustment buckle 40 may be made of different materials without departing from the scope of the present invention. The adjustment buckle 40 should be made of a material that is non-corrosive so that the adjustment buckle 40 does not rust in the wet environment. Through testing, the inventors have found that 24-gauge 316 passivated stainless steel may be used as the material for the adjustment buckle 40. Additionally, other materials may be used for the material for the adjustment buckle 40 without departing from at least some examples of this invention, such as plastic or other non-corrosive metals.
Additionally, the adjustment connector 52 may be made of different materials without departing from the scope of the present invention. The adjustment connector 52 should also be made of a material that is non-corrosive so that the adjustment connector 52 does not rust in the wet environment. Through testing, the inventors have found that a plastic rivet may be used for the adjustment connector 52 (e.g., Pine-Tree Clip black, Thread Rite Screw Products, Part #M36 0300 02). Additionally, other materials, such as screws, pins, etc., may be used for the adjustment connector 52 without departing from at least some examples of this invention, such as stainless steel or other non-corrosive metals.
As shown in
The angle of the hook 60 may also be important to catching and retaining the non-dispersing cloths while allowing other materials to pass. The inventors have found that the optimal angle for the hooks 60 is between approximately 45 and 60 degrees angled away from the strap 20 with the point of the hook 60 facing into the toilet bowl 14. When the hooks 60 are angled at 90 degrees, it was found that the cloths would catch and then fall off. In an embodiment in accordance with this invention, the angle of the hooks 60 is less than 90 degrees and greater than approximately 15 degrees. The number, location, and angle of the hooks 60 can vary without departing from at least some examples of this invention.
The hooks 60 may be made of different materials without departing from the scope of the present invention. The hook material should be rigid and inflexible. The hook material should be able to remain substantially in position during toilet bowl cleaning, and if moved from position, go back into substantially the same position after the cleaning. Additionally, the hook material should be a non-corrosive material so that the hooks 60 do not rust in the wet environment. Also, the hooks 60 may be sharp, such as sharp enough to catch the non-dispersing cloths, while being able to break or cut through the toilet paper and waste in the toilet 14. Additionally, barbed hooks 60 may be used without departing from at least some examples of the invention. The barbed hooks 60 may have a “T” barb to catch the non-dispersing cloths. Additionally, the adjustment buckle 40 may include a tooth 45 which acts as another hook, as illustrated in
The trapping device 10, as described above, may be installed in a toilet 14 by a user. To install the trapping device 10, the user may first prepare the trapping device 10 for installation, as shown in
As illustrated in
As illustrated in
Additionally, as illustrated in
The color of the trapping device 10 has been found to be important when installed in the toilet bowl 14. Through testing, the inventors have found that a strap 20 with a color in contrast with the non-dispersing clothes is useful. For example, a black strap 20 contrasts with the caught white non-dispersing clothes for the user, who may be responsible for removing the caught cloths from the trapping device 10. The inventors found when using white plastic for the strap 20, the white strap 10 does not contrast enough with the white non-dispersible cloths and the white toilet bowl 14 and therefore it was hard to differentiate the caught cloths from the trapping device 10. Other colors may be used for the trapping device 10 or the strap 20 without departing from at least some examples of this invention, as long as the color contrasts with the white non-dispersible cloths.
Additionally, the user may utilize a disposable retrieval hook to retrieve the cloths that have been caught by the trapping device 10. The retrieval hook may be a metal or plastic hook designed to retrieve cloths from the trapping device 10.
Once installed, the trapping device 10 can also be removed from the toilet bowl 14. The user may need to use pliers or a similar tool to remove the trapping device 10 from the toilet bowl trapway 12 because of the close fit and the combination of the rivet 52 and the front tab 44 fit with the top of the toilet bowl trapway 12. Additionally, the trapping device 10 may be semi-permanently installed in the toilet bowl 14. This semi-permanent installation may be accomplished by using epoxy or cement or some other glue material without departing from the scope of this invention.
As shown in
Additionally, as shown in
As described above for
When installing the glue-in trapping device 210 as described above, the user places and holds the mini-strap 220 in a preferred location. The hole 221 in the mini-strap 220 allows for the epoxy to be squeezed through the mini-strap 220 when pressed against the toilet bowl 14 and flattened against the other side. This epoxy may form an epoxy “rivet”/head that holds the mini-strap 220 and the hooks 260 securely in place on the toilet bowl 14. The toilet bowl 14 should be completely dry to stick the epoxy. The epoxy may be an underwater epoxy, thereby allowing the epoxy to dry underwater and allowing for a quick installation and quick return to use for the toilet bowl 14. There may be four mini-straps 220 affixed to the top and sides of the toilet bowl trapway 12 and one additional mini-strap 220 may be affixed to the bottom of the trapway 12 for reasons as discussed above. Additionally, depending on the size of the toilet bowl 14, the number of mini-straps 220 can increase or decrease without departing from at least some examples of this invention. Additionally, a “mini-strap” mounting peg may be permanently attached, wherein the removable “mini-strap” may be affixed to the mounting pegs and changed out or replaced if damaged.
In another example trapping device 10 according to aspects of this invention, the strap 20 and the trapping device 10 as discussed above and illustrated in
In another example trapping device 10 according to aspects of this invention, the hooks 60 may be installed or formed integral to the toilet bowl 14. For example, during the manufacturing process of the toilet bowl 14, a plurality of hooks 60 may be singularly installed within the ceramic of the toilet bowl 14, thereby making the hooks 60 a permanent fixture of the toilet bowl 14. The location and number of hooks 60 may be similar to those as discussed above for
