DETAILED DESCRIPTION

The present invention is generally directed to toilets and toilet seats with self-containing waste systems.

None of the prior art discloses foldable toilet seats or the use of a top cushion and/or top layer in order to convert the portable toilet into a normal camping chair.

A major issue for people who partake in outdoor activities, such as camping and/or hiking, is the need to use the restroom when one is not available. Attempting to use the restroom outdoors can lead to contamination and unsanitary campgrounds or hiking trails for up to several weeks after the incident. Specifically, should this occur, people in the area have an increased risk of exposure to pathogens and helminths that may cause respiratory disease, Cholera, Hepatitis A, and other similar diseases.

These risks may additionally be increased for unhoused people who may not have access to indoor restrooms the majority of the time. These people likely need to use the restroom outdoors several times per day, which increases their risk of spreading and/or contracting one or more of the associated diseases due to frequent exposure. For unhoused people who live in communities with other unhoused people, this risk rises again due to the increased number of contaminants.

Therefore, there is a need for a more portable toilet system that ensures ease of use and increased sanitation. The present invention is directed to a more portable toilet system to solve such a problem. The camping chair toilet system is portable and multi-functional due to its foldable toilet seat and top cushion. Specifically, the camping chair toilet system is designed to provide users with both a portable toilet and a chair to relax in.

Referring now to the drawings in general, the illustrations are for the purpose of describing one or more preferred embodiments of the invention and are not intended to limit the invention thereto.

In the preferred embodiment, thetoilet system400 is fitted for an adult of average size and includes afoldable toilet seat100, aportable camping chair200, atop cushion210, awaste bag500, and/orrubber bands510 to support the waste bag. Thetoilet seat100 has twohinges120, which enables thetoilet seat100 to fold and unfold, and fourhooks110, which are permanently affixed and hold thewaste bag500 below theseat opening230. In this embodiment, thehooks110 are operable to collapse to allow thetoilet seat100 to completely fold, such that both sides lay flat on each other. Also in this embodiment, thehooks120 fit within their own fourhook holes220 to prevent thetoilet seat100 from sliding and/or rotating while in use. To better secure thewaste bag500 to thehooks110,rubber bands510 are used. However, one of ordinary skill in the art will appreciate the present invention is readily adaptable to include any number ofhooks110 and corresponding hook holes220, as well as any number ofwaste bags500 securing devices (i.e., rubber bands510). As a nonlimiting example, atoilet seat100 includes fivehooks110 and five corresponding hook holes220. As another nonlimiting example, atoilet seat100 includes sixhooks110 and six corresponding hook holes220.

Additionally, one of ordinary skill in the art will understand, that while the preferred embodiment is directed to accommodating an average-sized adult, thetoilet system400 is modifiable to accommodate any person or any child.

Non-Collapsible Toilet Component

FIGS.7A-7B illustrate a toilet component according to one embodiment of the present invention. Thetoilet component550 of the present invention is configured to be inserted into the opening in the seat of the chair. The embodiments shown inFIGS.7A-7B and subsequently inFIGS.8A-8C below represent an alternative embodiment to the folding seat shown inFIGS.1A and1B. Thetoilet component550 is preferably removable from the seat of the chair, such that the chair is able to be effectively folded and stored and such that the toilet component is able to be effectively emptied and cleaned. In one embodiment, thetoilet component550 includes two separable subcomponents, a top subcomponent and abottom base subcomponent560.FIG.7A shows the combination of both the top subcomponent and thebottom base subcomponent560, whileFIG.7B shows only thebottom base subcomponent560.

The top subcomponent includes aseat552 connected via ahinge554 to abowl558. The center of the bottom of thebowl558 includes an opening into which thebottom base subcomponent560 is able to be inserted. Thebottom base subcomponent560 is an elongated reservoir having arim562 with a wider radius than the rest of the reservoir. In one embodiment, thebottom base subcomponent560 is substantially cylindrically, but one of ordinary skill in the art will understand that rectangular prisms, hexagonal prisms, and other similar shapes are also acceptable for use in the present invention. The radius of thebottom base subcomponent560 is configured to be similar to or lesser than the radius of the opening at the bottom of thebowl558, but therim562 has a wider radius than the opening at the bottom of thebowl558. This allows thebottom base subcomponent560 to be fit through the opening, while therim562 retains connection between the top subcomponent and thebottom base subcomponent558. In one embodiment, the radius of the elongated reservoir and the opening are roughly matched such that an interference fit is formed, while, in another embodiment, an interference fit is not used, but gravity holds the two subcomponents together.

Theseat554 is able to hingedly rotate about thehinge554 to put theseat554 up and down. In one embodiment, atab556 extends laterally from theseat552, which is able to serve as a sanitary grip to use to lift and put down theseat554.

Preferably, thebottom subcomponent560 is closed at the bottom to catch any material. However, one of ordinary skill in the art will understand that thebottom subcomponent560 is also able to be open at the bottom.

Collapsible Toilet Component

FIGS.8A-8C illustrates a collapsible toilet component in three different configurations according to one embodiment of the present invention. While the embodiment inFIGS.7A-7B utilizes a rigid, non-collapsible toilet component, thetoilet component600 shown inFIGS.8A-8C is collapsible. Like the embodiment shown inFIGS.7A and7B, thetoilet component600 includes a top subcomponent and abottom subcomponent610, with the top subcomponent including aseat602 attached via ahinge604 to abowl608. The bottom of thebowl608 includes an opening through which thebottom subcomponent610 is inserted. Atab606 extends laterally from theseat602 as a sanitary grip for lifting and putting down theseat602.

As shown inFIG.9, thebottom subcomponent610 includes arim611 with a radius larger than the rest of thebottom subcomponent610 and larger than the radius of the opening in the bottom of thebowl608 of the top subcomponent.

Thebottom subcomponent610 includes a plurality ofannular ribs612 connected by a plurality ofcollapsible sections614. The plurality ofannular ribs612 are rigid pieces (e.g., formed from a metal, such as stainless steel, a rigid plastic, or a rigid ceramic material) that provide structure to thebottom subcomponent600. In one embodiment, from top to bottom, the plurality ofannular ribs612 have increasingly narrow radii, providing a tapered structure to thebottom subcomponent610. The plurality ofcollapsible sections614 are preferably formed from a soft, easily malleable material (e.g., low-density polyethylene (LDPE), that is able to fold inwardly in the collapsed position, but preferably retain the shape of thebottom subcomponent610 when it is moved back to the extended configuration. In one embodiment, thebottom subcomponent610 does not include a plurality ofcollapsible sections614, but rather thebottom subcomponent610 is structurally formed from the soft, malleable material (e.g., LDPE) with the plurality ofannular ribs612 attached to an exterior of the material to provide structure and weighting to the material.

The use of thebottom subcomponent610 in the fully extended state (i.e., when the plurality ofribs612 are maximally separated and thecollapsible sections614 are maximally taut) is helpful, as it provides additional distance from a user and therefore decreased splash issues. Furthermore, in the extended confirmation, thebottom subcomponent600 has increased volume. However, the ability to collapse thebottom component600 into the configuration shown inFIG.8C allows for easier transport.

In an alternative embodiment, the top subcomponent and thebottom subcomponent610 are not separable pieces, but integrally formed.

Preferably, thebottom subcomponent610 is closed at the bottom to catch any material. However, one of ordinary skill in the art will understand that thebottom subcomponent610 is also able to be open at the bottom.

Dual Cupholder-Toilet Paper Holder

FIGS.10A and10B illustrate a dual cup holder and toilet paper holder in retracted and extended positions according to one embodiment of the present invention. In one embodiment, the holdingapparatus630 includes acup holder634 having a semicircular cross-section. Aretractable prong636 extends outwardly from thecup holder634. In one embodiment, theretractable prong636 includes a horizontal portion substantially parallel to a base of thecup holder634 and a vertical portion extending upwardly that is substantially orthogonal to the horizontal portion. The horizontal portion is connected to a bottom surface of the base of thecup holder634 and is able to retract and extend from the base.

Theretractable prong636 is able to serve a dual purpose. If a cup is placed on thecup holder634, then theretractable prong636 serves as a wall of thecup holder634 for keeping the cup in place. Alternatively, if toilet paper is placed on the holdingapparatus630, then theretractable prong636 is able to be inserted into the central hole of the roll of toilet paper (as toilet paper rolls tend to be much larger than cups). The retractability of theretractable prong636 allows the holdingapparatus630 to accommodate different cup sizes as well as different sizes of toilet paper rolls. It also allows the holdingapparatus630 to adjust to the changing size of the toilet paper roll as the roll is used.

In one embodiment, aclasp632 extends laterally outwardly from a side of thecup holder634. In one embodiment, theclasp632 extends from an opposite side of thecup holder634 relative to theretractable prong636, but one of ordinary skill in the art will understand that the relative arrangement of theclasp632 and theretractable prong636 are not intended to be limited according to the present invention. Theclasp632 is configured to snap onto an armrest of a chair, allowing the cup or toilet paper roll to be within easy reach.

Chair With Roof and Privacy Hood

FIG.11A illustrates a perspective view of a chair with a hole to receive a toilet component according to one embodiment of the present invention. Achair650 according to the present invention is able to have a seat through which ahole656 is defined. In one embodiment, thechair650 includes a seat back and armrests. In one embodiment, one ormore holding apparatuses630, as described with reference toFIGS.10A-10B, are attached to one or more of the arm rests. In one embodiment, one ormore supports654 extends upwardly from the chair650 (e.g., from the seat back) and is attached, at an upper end, to aroof component652. Theroof component652 provides shades and thereby additional comfort to thechair650.

In one embodiment, the seat of thechair650 includes at least two layers of material. In one embodiment, a top layer (e.g., a fabric layer) is configured for comfort for general sitting on thechair650 and does not include a central hole. This top layer is able to be stretched taut across the full width of the seat to prevent sagging of the material. In one embodiment, the top layer is attached to the supports of the chair650 (e.g., horizontal or vertical metal or hard plastic cross bars) via hook and loop elements, clasps, or other temporary attachment means. In one embodiment, the top layer is connected directly to a second or bottom layer of material, to the supports of thechair650, or to itself after being looped around one or more supports of thechair650.

In one embodiment, a second, or bottom, layer including thehole656 is positioned beneath the top layer and exposed when the top layer is removed. The tautness of the top layer is helpful for ensuring the top layer does not sag into thehole656 in the bottom layer. This allows for a more sanitary feeling when sitting on the top layer and allows for less easily stained and less irritative, but potentially less comfortable, materials to be used for the bottom layer.

As shown inFIG.11B, thetoilet component600 is able to be inserted into the hole in the seat (or more specifically in the bottom layer of the seat) of thechair650. Preferably the radius of the bottom subcomponent of thetoilet component600 is approximately equal to or less than the radius of the hole, allowing the bottom component to extend downwardly from the seat. However, the radius of the top component is preferably larger than the hole such that the top component, or at least the toilet seat, sits above the seat. Thechair650 is configured such that the crossbars of thechair650 between the legs of thechair650 do not obstruct thetoilet component600.

FIG.12 illustrates a perspective view of a chair with a hood covering it according to one embodiment of the present invention. In one embodiment, the chair is able to be fitted with ahood660, or a privacy tent, allowing the user to have privacy and not be as exposed to the elements (e.g., sun, rain, etc.). In one embodiment, thehood660 is connected to theroof component652 via one or more attachments, including but not limited to, hook and loop elements, pins, screws, nails, metal hooks on the roof and fabric loops on the hood, and/or other attachment means. In a preferred embodiment, thehood660 is connected to theroof component652 via side-release buckle elements attachment to the hood and theroof component652. In one embodiment, the hood includes660 anentrance666 for a user. In one embodiment, theopening666 includes an elongated zipper extending from the top to the bottom of thehood660. In one embodiment, theopening666 includes a flap able to be closed via hook and loop elements, buttons, clasps, or other means.

In one embodiment, thehood660 includes one ormore windows662. In one embodiment, the one ormore windows662 are covered with mesh to prevent insects from entering the hood, but to provide breathability for those inside. Furthermore, the windows provide information regarding whether thehood660 is currently empty and is able to be used by someone outside. In one embodiment, one or more privacy shades are included on the interior and/or exterior sides of thewindows662 that are able to close over thewindows662 to obstruct the view between the inside of outside, providing for appropriate privacy.

In one embodiment, in order to preserve the shape of thehood660 and keep thehood660 in place, thehood660 is anchored to the ground by one or more pins664. Thepins664 are able to be inserted through loops or holes proximate to the bottom edge of thehood660 and inserted into the ground to hold thehood660 in place. In the embodiment shown inFIG.12, fourpins664 are used, but one of ordinary skill in the art will understand that greater or fewer numbers ofpins664 are able to be used according to different sizes, shapes, environmental conditions, or other factors for thehood660. In one embodiment, thehood660 includes an outer waterproof layer for increased protection against rain, snow, and other environmental conditions.

FIG.13 is a partial top perspective view of a chair including a hole in a bottom layer according to one embodiment of the present invention.FIGS.13 and14 illustrate the orientation of the at least two layer system of the seat of thechair650 according to one embodiment.FIG.13 shows the state of thechair650 with the top layer removed, thereby exposing thehole656 in the bottom layer of the seat. Thishole656 allows for the insertion of the toilet component into thechair650.FIG.13 also illustrates several different, but not limiting, examples of means of affixation of the top layer to the bottom layer. For example, in one embodiment, a front edge of a top surface of the bottom layer includes a strip of hook orloop elements670 configured to mate with a corresponding strip of hook or loop elements on a bottom surface of the top layer. One of ordinary skill in the art will understand that the present invention also contemplates multiply of the strips of hook and loop elements and contemplates strip located on the side edges of the bottom layer in addition to or in lieu of thestrip670 at the front edge of the bottom layer. In one embodiment, one ormore clips672 are connected to a leg or armrest or frame component of the seat of thechair650, where the one ormore clips672 are able to be used to hold a top layer in place.

FIG.14 is a partial bottom perspective view of a chair with a top layer affixed to a bottom layer of the seat according to one embodiment of the present invention.FIG.14 shows a version of thechair650 with atop layer680 attached. Because the view inFIG.14 is from the bottom, thehole656 in the bottom layer remains visible, though thetop layer680 is covering a top surface of the bottom layer. In one embodiment, a bottom surface of the bottom layer includes one or more strips of hook orloop elements682 configured to matingly attach to one or more strips of hook and loop elements along the edges of thetop layer680. In the embodiment shown inFIG.14, side edges of thetop layer680 are configured to configured to overhang over side edges of the seat of thechair650 and loop around side supporting members of the seat of the chair to affix thetop layer680 to the bottom layer. Furthermore, by stretching the overhanging parts of thetop layer680 in order to connect the corresponding hook and loop elements (or other affixation means) of the layers, thetop layer680 is pulled tight and put into tension such that the center of thetop layer680 does not sag into thehole656 in the bottom layer.
