BACKGROUND OF THE INVENTION

The present invention relates to bathroom accessories and, more particularly, to a portable toilet seat.

Using a public restroom can be an adventure, in many ways. For one, toilet paper and toilet seat liners may not be available. And even if such paper products are in supply, they typically do not stop moisture and can stick to one's underside when used to line the top of the toilet seat. Furthermore, applying toilet paper to a public toilet seat takes time and sometimes there is no time. Moreover, using toilet paper or toilet seat liners further clogging our overburdened sewer systems. Of course, the toilet may not have a functioning toilet seat to begin with . . . .

As can be seen, there is a need for a portable toilet seat that is convenient to use and prevents unnecessary use of toilet paper and other paper products. The portable toilet seat embodied in the present invention allows a person to have use of a toilet seat if one is not available, and if one is available the present invention enables users to sit on their own personal toilet seat instead of a public toilet seat, providing a sanitary surface to sit on public toilets.

SUMMARY OF THE INVENTION

In one aspect of the present invention, a portable toilet seat includes a chain of arcuate portions pivotably connected in series so as the portable toilet seat is foldable among a flat condition, a first folded condition and a second folded condition.

In another aspect of the present invention, the portable toilet seat includes the following: a chain of arcuate portions pivotably connected in series by living hinges so as the portable toilet seat is foldable among a flat condition, a first folded condition and a second folded condition, wherein the first folded condition the portable toilet seat is folded in half, and wherein the second folded condition the portable toilet seat is folded in quarters; a plurality of radial fins provided along the bottom surface of the chain of arcuate portions, each radial fin extending radially from an inner portion of the bottom surface to an outer surface thereof; and a concentric slot formed in each of at least two of the plurality of radial fins so that in the second folded condition each concentric slot securely engages a radial fin on an opposing arcuate portion, wherein each concentric slot has a curvature, and wherein each concentric slot shares a distance to a center of a main opening defined by the flat condition.

DETAILED DESCRIPTION OF THE INVENTION

Broadly, an embodiment of the present invention provides a portable toilet seat for user over pre-existing toilet seats or in lieu of a broken or missing toilet seat. The portable toilet seat provides a chain of arcuate portions pivotably connected in series so as to be adapted to fold among a flat condition, a first folded condition and a second folded condition. The bottom side of each arcuate portions may provide radial fins, each radial fin may provide a concentric slot. The concentric slots share a radial distance from a center of the opening defined in the flat condition so that in such a condition the concentric slots may engage a rim of a toilet, while in the second folded condition the concentric slots securely engage the radial fins of opposing arcuate portions.

Referring toFIGS. 1 through 5, the present invention may include a portable toilet seat10/30providing a chain of arcuate portions12/32pivotably connected in series. The pivotable connections14may be living hinges so as minimize components, weight, manufacture time and cost; though in alternative embodiments the pivotable connection14may be other hinges or types of pivotable connection. The living hinges may have different widths, as illustrated in comparison ofFIGS. 3 and 4, withFIGS. 1 and 2. Also, the living hinges may be formed into a top surface or a bottom surface of the portable toilet seat10/30. The portable toilet seat10/30may be made out of various plasticized materials, and in some embodiments a plasticized film so that the portable toilet seat10/30would be affordably disposable after a one-time use.

The arcuate portions12may include a first portion having a first top and an opposing bottom surface12aand12a′, a second portion having a second top and an opposing bottom surface12band12b′, a third portion having a third top and an opposing bottom surface12cand12c′, and a fourth portion having a fourth top and an opposing bottom surface12dand12d′. The first portion and the second portion may be mirror images of each other and associated with the rear of the portable toilet seat10/30, while the third portion and the fourth portion may be mirror images of each other, wherein the third and fourth portions are associated with a front of the portable toilet seat10/30, and provide a gap at their distal ends commonly found in a conventional toilet seat, as illustrated inFIGS. 1 and 3.

The pivotable connections14enable the portable toilet seat10/30to be foldable among a flat condition, a first folded condition, and a second folded condition. The flat condition is for use as a toilet seat, as illustrated inFIGS. 1-4. The first folded condition may be folded in half lengthwise so that each top surface abuts an opposing top surface, as illustrated inFIG. 5. The second folded condition may be folded in quarters, as illustrated inFIG. 6. The folded conditions provide two convenient options for transport and storage, depending on the space available. For example, the second folded condition may be better suited for a backpack or purse, while the first folded condition is preferred when the height of the storage space is the critical limitation.

Along the bottom surfaces12a′, b′, c′ and d′ may be double radial fins16and/or single radial fins18. In certain embodiments, the double radial fins16may be spaced apart single radial fins16. The fins16and18are radial in that the generally extend from what would be a center of the toilet seat cover opening50. As a result, the fins16and18extend generally transverse to each associated bottom surface, as illustrated inFIG. 2. Each fin16and18may provide a concentric slot22and24cut out of a portion of the respective fin16or18inward from the inner (nearer the toilet seat cover opening50). Each concentric slot22and24may be concentric with each other as in the share a concentric distance from said center of the toilet seat cover opening50. Furthermore, the concentric slots22and24may have a concentric curvature (as opposed to a perpendicular cut) through the associated fin16and18. The critical aspect of the design of concentric slots22and24is that the concentric slots22and24may be dimensioned and adapted to engage a rim of a cylindrical toilet bowl, basin or bucket20to keep the portable toilet seat cover10/30secure during use, as well as to be dimensioned and adapted to engage each other in the second folded condition.

In the second folded condition, the fourth portion bottom surface12d′ folds back onto the second portion bottom surface12b′, and/or the first third bottom surface12c′ folds back onto the first portion bottom surface12a′. In the second folded condition, the concentric slots24of the singular radial fins18would align and engage with the double radial fins16and/or the concentric slots22of the double radial fins16would align and engage with a single radial fin18.

A method of using the present invention may include the following. The portable toilet seat10/30disclosed above may be provided. In the flat condition, a user may place the bottom surface (12a′, b′, c′, d′) on either a pre-existing lowered toilet seat (so as not to have to sit on it, most likely in a public restroom situation) or may place said bottom surface along the rim of a toilet bowl that has a missing or broken toilet seat. Th present invention can be used on construction sites where porta-potties are used. By a portable toilet seat10/30in the user's tool belt, for example, the user would be ensured of a sanitary toilet seat even if the toilet seat is missing. If the pre-existing toilet seat is missing or broken, many porta-potties “toilet basins” are cylindrical with thin sidewalls wherein the user may utilize the concentric slots22and/or24along the rim of such a cylindrical basin. Or when camping or hunting or otherwise in a pinch, the user may use a bucket by placing the portable toilet seat10/30along the rim20of the (say, five gallon) bucket so that the concentric slots22and/or24engaged said rim20, as illustrated inFIG. 1.

After taken care of one's business, the user may fold the portable toilet seat10/30into the first or second folded condition for transport or storage.
