Summary of Invention

Technical Problems

[0009] Portable personal toilet seats present at least five integrally interrelated problems that must all be solved simultaneously in a single embodiment in order to produce a superior portable personal toilet seat.

[0010] First, toilet seats can be plagued with undesirable and harmful viruses, bacteria, fungi, mold and mildew. Thus the problem exists as to how to create a toilet seat that has anti-viral, anti-bacterial, anti-fungal, anti-mold and anti-mildew properties that are inherent to the seat itself and which are not merely coatings that are susceptible to being wiped off or scraped off when the seat is used or cleaned.

[0011 ] Second, three interrelated problems exist regarding how to design a seat that can be folded without pinching the user’s fingers, how to configure such a seat in an easily portable configuration and how to provide a means for a user to easily grasp the entire folded seat without the need for a handle.

[0012] Third, there is the problem of how to create alternatives to known foldable toilet seat designs.

[0013] Fourth, there is the problem of how to create a novel foldable toilet seat that provides the same or similar effects as existing foldable toilet seats.

[0014] Fifth, the problem of how to create a foldable toilet seat that is more cost-effective than existing toilet seats is a significant problem that needs to be resolved.

[0015] Collectively, at least the preceding problems comprise the objective technical problem of how to produce a superior toilet seat.

Solutions to the Problems

[0016] One solution to the problem of how to create a toilet seat that has anti-viral, anti-bacterial, anti-fungal, anti-algae, anti-mold and anti-mildew properties that are inherent to the seat itself and that are not merely coatings that can be wiped off or scraped off like a mere coating could be is to have the toilet seat comprised of parts that have sources of metal ions mixed into them so as to impart anti-viral, anti-bacterial, and anti-fungal properties to the toilet seat.

[0017] One solution to the three interrelated problems of how to design a seat that can be folded without pinching the user's fingers, how to configure such a seat in an easily portable configuration and how to provide a means for a user to easily grasp the entire folded seat without the need for a handle, is to configure the seat in the manner disclosed herein.

[0018] One solution to the problems of how to create alternatives to known foldable toilet seats, how to create a foldable toilet seat that provides the same or similar effects as existing foldable toilet seats and how to create a foldable toilet seat that is more cost-effective than existing toilet seats, is to configure the seat in the manner disclosed herein.

Advantageous Effects of the Disclosed Embodiments

[0019] One advantage of the disclosed embodiments is that anti-viral, anti-bacterial, anti-fungal, anti-algae, anti-mold and anti-mildew properties are made inherent to the seat itself are not susceptible to inadvertent removal in the same manner that mere coatings are. [0020] Another advantage of the disclosed embodiments is that they can be folded without pinching the user's fingers, configured in an easily portable configuration and provide a means for a user to easily grasp the entire folded seat without the need for a handle.

[0021 ] Yet another advantage of the disclosed embodiments is that they provide alternatives to known foldable toilet seats, they provide the same or similar effects as existing foldable toilet seats and are more cost-effective than existing toilet seats.

Description of the Disclosed Embodiments

First Exemplary Embodiment: An Anti-Viral, Anti-Bacterial and Anti-Fungal Toilet Seat that is Resistant to Algae, Mold and Mildew and that Can Be Safely Folded and Held without the Danger of Pinched Fingers [0076] Viruses, such as COVID-19, bacteria, fungus, mold and mildew can all pose significant hygienic challenges, particularly within the context of portable foldable toilet seats. The disclosed embodiments show how to address these challenges within the context of a mechanically novel portable foldable toilet seat that can be safely folded and held without the danger of pinched fingers and without the need for a dedicated handle.

[0077] Silver ions, Ag ⁺ , are effective for combating viruses, bacteria, fungi, algae, mold and mildew. Ions of copper, zinc, iron, gold, platinum, palladium, lead, tin, mercury, cadmium, chromium, nickel and cobalt also possess similar desirable properties. However, the problem is how to turn a portable toilet seat into a vehicle for consistently delivering a sufficient supply of metallic ions over an extended period of time so that the user of the portable toilet seat can realize the benefits of the presence of metallic ions, even after the seat has been used many times, has been cleaned repeatedly and may have been scratched or have suffered mechanical damage.

[0078] A solution to this problem is to make the seat out of a plastic, such as, for example, Acrylonitrile Butadiene Styrene ("ABS"), that is impregnated with silver-containing ion-exchange resins, such as soluble glass or zirconium phosphate. This will allow the portable foldable toilet seat to serve as a vehicle for consistently delivering a sufficient supply of metallic ions over an extended period of time, thus creating a toilet seat with properties that combat viruses, bacteria, fungi, algae, mold and mildew.

[0079] As a non-limiting example, it is possible to provide for the gradual dissemination of metallic ions onto the surface of a portable foldable toilet and to thereby impart to the seat anti-viral, anti-bacterial, anti-fungal, anti-algae, anti-mold and anti-mildew properties. This can be done by making the portable foldable toilet seat out of a plastic such as, for example, ABS, and impregnating the ABS with inorganic carrying compounds that are capable of dissociating into metal ions, said inorganic carrying compounds including substances such as soluble glass, zirconium phosphate, calcium phosphate, zeolite, silica gel, titanium oxide and porous ceramics that contain, and allow for the dissemination of, metal ions via ion-exchange, said metal ions comprising one or more metals such as silver, copper, zinc, iron, gold, platinum, palladium, lead, tin, mercury, cadmium, chromium, nickel and cobalt.

[0080] As a further non-limiting example, soluble silicates, such as Ishizuka Glass Co., Ltd.’s IONPURE brand soluble silver glass can be used in a concentration of at least 2 percent up to a Maximum Concentration of 6 percent on a dry weight basis of finished products, in ABS plastic to fabricate the disclosed portable foldable toilet seat. The result of doing this is that the glass will dissolve and release silver, zinc or copper ions onto the surface of the portable toilet seat. The effect of this will be to suppress viruses as well as the growth of bacteria, algae, fungus, mold and mildew, as well as the unpleasant odors, discoloration and staining that can be caused by bacteria, algae, fungus, mold and mildew. The soluble glass will dissolve when exposed to moisture, such as human sweat, thereby releasing the desired metal ions onto the surface of the portable foldable toilet seat. Other sources of moisture such as humidity and the application of water will have the same effect.

[0081 ] As another non-limiting example, zirconium phosphate can be used as a silver ion carrier and mixed into ABS plastic to fabricate the disclosed portable foldable toilet seat. Alphasan® RC 2000 (Milliken and Co., Spartanburg, SC) is an example of a commercially available metal ion carrier that can be used to obtain the slow release of metallic ions onto a portable foldable toilet seat when it is mixed with ABS plastic. Alphasan is a zirconium phosphate-based ceramic ion-exchange resin containing silver.

[0082] The mechanics of how to construct an exemplary embodiment of the new portable foldable toilet seat are illustrated in the attached drawings, which are summarized in part below. The exemplary embodiment illustrated below employs a plurality of stanchions and raised pivot supports on a right front folding piece, a right rear folding piece, a left front folding piece and a left rear folding piece. The stanchions support the new portable foldable toilet seat and raise it off of the permanent toilet seat or toilet bowl, along with the raised pivot supports and the hinge connection means that join the front and rear pieces together. The proportions of the height of the stanchions to the height of the raised pivot supports enable, in part, the novel nature of the disclosed embodiment.

[0083] Specifically, the following proportions should be used when constructing the disclosed exemplary embodiment:

[0084] as to the right front folding piece (2):

a raised pivot support (215) protruding downward from the bottom surface (210) of the right front folding piece (2) that is at least the longer of the distance that the tallest right front stanchion (211 ) protrudes from the bottom surface (210) of the right front folding piece (2) or of the distance that the tallest right rear stanchion (41 1 ) protrudes from a bottom surface

(410) of a right rear folding piece (4);

[0085] as to the right rear folding piece (4):

a raised pivot support (415) on the anterior surface (49) protruding downward from the bottom surface (410) of the right rear folding piece (4) that is at least the longer of the distance that the tallest right front stanchion (211 ) protrudes from the bottom surface (210) of the right front folding piece (2) or of the distance that the tallest right rear stanchion

(41 1 ) protrudes from the bottom surface (410) of the right rear folding piece (4);

[0086] as to the left rear folding piece (8):

a raised pivot support (815) on the anterior surface (89) protruding downward from the bottom surface (810) of the left rear folding piece (8) that is at least the longer of the distance that the tallest left front stanchion (1001 1 ) protrudes downward from the bottom surface (10010) of the left front folding piece (10) or the distance that the tallest left rear stanchion (81 1 ) protrudes from the bottom surface (810) of the right rear folding piece (8); [0087] and as to the left front folding piece (10):

a raised pivot support (10015) protruding downward from the bottom surface (10010) of the left front folding piece (10) that is at least the longer of the distance that the tallest left front stanchion (1001 1 ) protrudes from the bottom surface (10010) of the left front folding piece (10).

[0088] Additionally, the disclosed embodiment illustrates that:

[0089] any right rear stanchions (411 ) that extend down from the bottom surface

(410) are to be positioned in such a manner that no right rear stanchion

(41 1 ) will make contact with any right front stanchion (21 1 ) when the right front folding piece (2) is folded toward the right rear folding piece (4); and

[0090] any left rear stanchions (81 1 ) that extend down from the bottom surface

(810) are to be positioned in such a manner that no left rear stanchion

(81 1 ) will make contact with any left front stanchion (1001 1 ) when the left front folding piece (10) is folded toward the left rear folding piece (8).

[0091 ] Other features of the disclosed exemplary embodiment are described in the discussions below of the accompanying drawings and the various elements disclosed therein, whether or not those elements are identified by specific numbers or lead lines.

[0092] Figure 1 shows an embodiment of a portable foldable toilet seat (1 ) that can be grasped by a human hand (1200) when folded into an easily portable configuration that does not pinch any fingers and without the need for a handle. Figure 1 discloses an embodiment of a portable foldable toilet seat comprised of a right front folding piece (2), a right rear folding piece (4), a left and right rear connecting piece (6), a left rear folding piece (8), and a left front folding piece (10).

[0093] Figure 2 reveals a fully deployed configuration of the portable foldable toilet seat (1 ) of Figure 1 as viewed from the top, that is, from the side that interfaces with a user of the seat. The right front folding piece (2), right rear folding piece (4), left and right rear connecting piece (6), left rear folding piece (8) and left front folding piece (10) are all depicted as being deployed circumferentially around a central aperture (1 1 ).

[0094] Figure 3 reveals a fully deployed configuration of the portable foldable toilet seat (1 ) of Figure 1 as viewed from the bottom, that is, from the side that interfaces with a toilet bowl or on a toilet seat. In addition to showing the right front folding piece (2), right rear folding piece (4), left and right rear connecting piece (6), left rear folding piece (8), and left front folding piece (10) deployed circumferentially around a central aperture (11 ), Figure 3 also shows a right front stanchion (21 1 ), a right rear stanchion (41 1 ), a right rear stanchion (81 1 ), and a left front stanchion (1001 1 ). Figure 3 further shows that the right front folding piece (2) is connected to the right rear folding piece (4) by a hinge connection means (30), the right rear folding piece (4) is connected to the left and right rear connecting piece (6) by a hinge connection means (50), that the left and right rear connecting piece (6) is connected to the left rear folding piece (8) by a hinge connection means (70), and that the left rear folding piece (8) is connected to the left front folding piece (10) by a hinge connection means (90).

[0095] In Figure 3, each of the following elements are depicted as being in a first position, i.e., fully deployed for the toilet seat to be sat upon: the right front folding piece (2), the right rear folding piece (4), the left and right rear connecting piece (6), the left rear folding piece (8), and the left front folding piece (10).

[0096] The same exemplary embodiment depicted in Figure 2 and Figure 3 is also depicted in Figure 4 (front elevation), Figure 5 (left elevation), Figure 6 (rear elevation), and Figure 7 (right elevation).

[0097] Figure 8 illustrates an exemplary embodiment of a hinge connection means (30) connecting a right front folding piece (2) to a right rear folding piece (4) from a bottom left perspective view. The hinge connection means (30) illustrated in Figure 8 is comprised of a plurality of raised pivot supports (215) that are structurally part of the right front folding piece (2), a plurality of raised pivot supports (415) that are structurally part of the right rear folding piece (4), and a means for pivoting (32), such as, for a non limiting example, the hinge pin that is illustrated in Figure 8. The structure of the plurality of raised pivot supports (215 & 415) that interfaces with and is immediately adjacent to the means for pivoting (32) is known as the pivot of the hinge (31 ) between the right front folding piece (2) and the right rear folding piece (4). However, the hinge connection means connecting the right front folding piece (2) to the right rear folding piece (4) could also, as a non-limiting example, be comprised of a pivot such as a living hinge, or a barrel hinge.

[0098] Figure 9 illustrates an exemplary embodiment of a hinge connection means (90) connecting a left front folding piece (10) to a left rear folding piece (8) from a bottom left perspective view. The hinge connection means (90) is comprised of a plurality of raised pivot supports (10015) that are structurally part of the left front folding piece (10), a plurality of raised pivot supports (815) that are structurally part of the left rear folding piece (8), and a means for pivoting (92), such as, for a non-limiting example, the hinge pin that is illustrated in Figure 8. The structure of the plurality of raised pivot supports (10015 & 815) that interfaces with and is immediately adjacent to the means for pivoting (92) is known as the pivot of the hinge (91 ) between the left front folding piece (10) and the left rear folding piece (8). However, the hinge connection means connecting the left front folding piece (10) to the left rear folding piece (8) could also, as a non-limiting example, be comprised of a pivot such as a living hinge, or a barrel hinge.

[0099] Figure 10 is a bottom rear perspective view of exemplary embodiments of a left and right rear connecting piece (6), of a hinge connection means (50) that connects the left and right rear connecting piece (6) to the right rear folding piece (4), and of a hinge connection means (70) that connects the left and right rear connecting piece (6) to the left rear folding piece (8). A right side (60) and a left side (66) of the left and right rear connecting piece (6) are also depicted in Figure 10.

[0100] The exemplary embodiment illustrated in Figure 10 discloses a hinge connection means (50) comprised of a plurality of raised pivot supports (415) that are structurally part of the right rear folding piece (4), a plurality of raised pivot supports (615) that are structurally part of a left and right rear connecting piece (6), and a means for pivoting (52), such as, for a non-limiting example, a hinge pin. The structure of the plurality of raised pivot supports (415 & 615) that interfaces with and is immediately adjacent to the means for pivoting (52) is known as the pivot of the hinge (51 ) between the right rear folding piece (4) and the left and right rear connecting piece (6). However, the hinge connection means connecting the left and right rear connecting piece (6) to the right rear folding piece (4) could also, as a non-limiting example, be comprised of a pivot such as a living hinge, or a barrel hinge.

[0101 ] The exemplary embodiment illustrated in Figure 10 also discloses a hinge connection means (70) comprised of a plurality of raised pivot supports (815) that are structurally part of the left rear folding piece (8), a plurality of raised pivot supports (615) that are structurally part of a left and right rear connecting piece (6), and a means for pivoting (72), such as, for a non-limiting example, a hinge pin. The structure of the plurality of raised pivot supports (615 & 815) that interfaces with and is immediately adjacent to the means for pivoting (72) is known as the pivot of the hinge (71 ) between the left rear folding piece (8) and the left and right rear connecting piece (6). However, the hinge connection means connecting the left and right rear connecting piece (6) to the left rear folding piece (8) could also, as a non-limiting example, be comprised of a pivot such as a living hinge, or a barrel hinge.

[0102] Figure 1 1 is a bottom left front perspective of an exemplary embodiment showing the right front folding piece (2) folded into a second position, while the right rear folding piece (4), the left and right rear connecting piece (6), the left rear folding piece (8), and the left front folding piece (10) are all in a first position, i.e., fully deployed for the toilet seat to be sat upon.

[0103] Figure 12 is a bottom left front perspective of an exemplary embodiment showing a right front folding piece (2) folded into a second position and a left front folding piece (10) folded into a second position. [0104] Figure 13 is a bottom rear perspective view of an exemplary embodiment in which a right front folding piece (2) is shown in a second position, a right rear folding piece (4) is shown in a second position, a left front folding piece (10) is shown in a second position and a left rear piece (8) is shown in a second position; this is the same configuration that is depicted in Figure 1 as an exemplary embodiment of a toilet seat that has been folded without pinching the user's fingers, configured in an easily portable configuration that provides a means for a user to easily grasp the entire folded seat without the need for a handle.

[0105] Figure 20 is a top right perspective view of an exemplary embodiment of a portable foldable toilet seat (1 ) deployed on a toilet bowl. A central aperture (1 1 ) of the portable foldable toilet seat is also identified in Figure 20.

[0106] Figure 21 is a top right perspective view of an exemplary embodiment of a portable foldable toilet seat (1 ) deployed on a permanent toilet seat (1204). A central aperture (1 1 ) of the portable foldable toilet seat is also identified in Figure 21.

[0107] Figure 22 is a top plan view of an exemplary embodiment of a right front folding piece (2). That Figure depicts the right front folding piece (2) as being comprised, in part, of a right front outer perimetric surface (21 ) extending from an outer anterior apex (22) to an outer posterior apex (23), a right front posterior surface (24) extending from the outer posterior apex (23) to an inner posterior apex (27), a right front inner perimetric surface (25) extending from the inner posterior apex (27) to an inner anterior apex (26) and an open right front surface (28) extending from the inner anterior apex (26) to the outer anterior apex (22); and a top sitting surface (200) that constitutes the top of the right front folding piece (2). An exemplary embodiment of a means for pivoting (32) is also illustrated as a cylindrical hinge pin.

[0108] Figure 23 is a bottom plan view of an exemplary embodiment of a right front folding piece (2). That Figure depicts the right front folding piece (2) as being comprised, in part, of right front outer perimetric surface (21 ) extending from an outer anterior apex (22) to an outer posterior apex (23), a right front posterior surface (24) extending from the outer posterior apex (23) to an inner posterior apex (27), a right front inner perimetric surface (25) extending from the inner posterior apex (27) to an inner anterior apex (26) and an open right front surface (28) extending from the inner anterior apex (26) to the outer anterior apex (22). These elements bound the bottom surface

(210) that constitutes the bottom of the right front folding piece (2). An exemplary embodiment of a means for pivoting (32) is also illustrated as a cylindrical hinge pin which would fit through the cylindrical hole in the raised pivot support (215) [said cylindrical shaped hole constituting the pivot of the hinge (31 ) depicted in Figure 27] to join the right front folding piece (2) to the right rear folding piece (4) as part of the hinge connection means (30) identified in Figure 8.

[0109] Figure 24 is a front elevation view of an exemplary embodiment of a right front folding piece (2). In addition to showing the raised pivot support (215), the Figure provides detail regarding the right front stanchion (21 1 ). The exemplary embodiment of the right front stanchion (21 1 ) depicted in Figure 24 shows a right front stanchion

(21 1 ) protruding downward from the bottom surface (210) of the right front folding piece (2), the right front stanchion comprising a sloped surface (212), an inner terminus of the stanchion (213); an outer terminus of the stanchion (214); and a raised pivot support (215) protruding downward from the bottom surface of the right front folding piece at least half of the distance that the right front stanchion protrudes from the bottom surface of the right front folding piece. Although the exemplary embodiment of a right front stanchion (21 1 ) depicted in Figure 24 is, geometrically, a stadium when viewed from a bottom plan perspective, it could be a circle, an ellipse, a square, a rectangle, or a polygon of any shape. The height of the stanchion from the bottom surface (210) is greater at the inner terminus of the stanchion (213) than at the outer terminus of the stanchion (214) in order to produce the sloped surface (212).

[01 10] It is useful to have a sloped surface on the stanchions of the right front foldable piece, the right rear foldable piece, the left rear foldable piece and the left front foldable piece because when all of these pieces have sloped surfaces sloping toward the central aperture, the weight of the user will be directed partially outward from the central aperture, thereby increasing the friction between the portable foldable toilet seat and the toilet bowl or permanent toilet seat on which the portable foldable toilet seat sits, thereby making it less likely that the portable foldable toilet seat will slide around while in use.

[01 11 ] Figure 25 is a left elevation view of an exemplary embodiment of a right front folding piece (2).

These elements bound the bottom surface (10010) that constitutes the bottom of the left front folding piece (10). An exemplary embodiment of a means for pivoting (92) is also illustrated as a cylindrical hinge pin which would fit through the cylindrical hole in the raised pivot support (10015) [said cylindrical shaped hole constituting the pivot of the hinge (91 ) depicted in Figure 45] to join the left front folding piece (10) to the left rear folding piece (8) as part of the hinge connection means (90) identified in Figure 9.

[0135] Figure 48 is a front elevation view of an exemplary embodiment of a left front folding piece (10). In addition to showing the raised pivot support (10015), the Figure provides detail regarding the left front stanchion (1001 1 ). The exemplary embodiment of the left front stanchion (1001 1 ) depicted in Figure 48 shows a left front stanchion (1001 1 ) protruding downward from the bottom surface (10010) of the left front folding piece (10), the left front stanchion comprising a sloped surface (10012), an inner terminus of the stanchion (10013); an outer term inus of the stanchion (10014); and a raised pivot support (10015) protruding downward from the bottom surface of the left front folding piece at least half of the distance that the left front stanchion protrudes from the bottom surface of the left front folding piece. Although the exemplary embodiment of a left front stanchion (1001 1 ) depicted in Figure 48 is, geometrically, a stadium when viewed from a bottom plan perspective, it could be a circle, an ellipse, a square, a rectangle, or a polygon of any shape. The height of the stanchion from the bottom surface (10010) is greater at the inner terminus of the stanchion (10013) than at the outer terminus of the stanchion (10014) in order to produce the sloped surface (10012).

[0136] It is useful to have a sloped surface on the stanchions of the right front foldable piece, the right rear foldable piece, the left rear foldable piece and the left front foldable piece because when all of these pieces have sloped surfaces sloping toward the central aperture, the weight of the user will be directed partially outward from the central aperture, thereby increasing the friction between the portable foldable toilet seat and the toilet bowl or permanent toilet seat on which the portable foldable toilet seat sits, thereby making it less likely that the portable foldable toilet seat will slide around while in use.

[0137] Figure 49 is a left elevation view of an exemplary embodiment of a left front folding piece. Figure 49 depicts a left front inner perimetric surface (1005), the raised pivot support (10015); the left front stanchion (1001 1 ), the inner terminus of the stanchion (10013), the outer terminus of the stanchion (10014) and the sloped surface (10012) extending between the two terminuses are also depicted.

An exemplary embodiment of a means for pivoting (92) is also illustrated as a cylindrical hinge pin which would fit through the cylindrical hole in the raised pivot support (10015) [said cylindrical shaped hole constituting the pivot of the hinge (91 ) depicted in Figure 45] to join the left front folding piece (10) to the left rear folding piece (8) as part of the hinge connection means (90) identified in Figure 9.

[0139] Figure 51 is a right elevation view of an exemplary embodiment of a left front folding piece. Figure 27 depicts one of the raised pivot supports (10015) and the pivot of the hinge (91 ) that is defined thereby. The stadium-shaped left front stanchion (1001 1 ) is also depicted, along with the left front outer perimetric surface (1001 ), the left front inner perimetric surface (1005), the inner posterior apex (1007), the open left front surface (1008) and the top sitting surface (10000).

[0148] In Figure 54, the living hinge (50) is both a means for pivoting the right rear folding piece (4) with respect to the left and right rear connecting piece (6) and a pivot of the hinge between the right rear folding piece (4) and the left and right rear connecting piece (6). Similarly, in Figure 54, the living hinge (70) is both a means for pivoting the left rear folding piece (8) with respect to the left and right rear connecting piece (6) and a pivot of the hinge between the left rear folding piece (8) and the left and right rear connecting piece (6).

[0160] Figure 15 is a right elevation view of an exemplary embodiment of a tractive pad member (1 100). The exemplary embodiment depicted in Figure 15 possesses a side wall (1 1 10). The illustrated exemplary embodiment shows a side wall (1 1 10) and a bottom surface (1 102). [0161 ] Figure 16 is a bottom left perspective of an exemplary embodiment of a tractive pad member (1100). In Figure 16, the bottom surface is depicted as containing a plurality of traction increasing features (1 104), such as, for example, the circular divots that are depressed below the bottom surface (1 102) as illustrated in Figure 16. However, in other exemplary embodiments, the traction increasing features (1104) could be singular or plural and also could be other shapes that are depressed below the bottom surface, such as, for example, an ellipse, a square, a rectangle, a polygon of any shape or an irregular or semi-irregular shape such as those found on the treads of tires or any combination thereof. In yet other exemplary embodiments, the traction increasing features (1104) could be singular or plural and also could be other shapes that are raised above the bottom surface, such as, for example, a dot, an ellipse, a square, a rectangle, a polygon of any shape or an irregular or semi-irregular shape such as those found on the treads of tires or any combination thereof. In still further exemplary embodiments, the traction increasing features (1 104) could be singular or plural, some of which could be depressed below the bottom surface (1 102) and some of which could be raised above the bottom surface and which could be a divot, a dot, an ellipse, a square, a rectangle, a polygon of any shape or an irregular or semi-irregular shape such as those found on the treads of tires or any combination thereof. In yet another exemplary embodiment, the bottom surface (1 102) illustrated in Figure 16 might be featureless without any voids of any shape below the bottom surface and devoid of any material protruding above the bottom surface, the traction increasing feature could be the material itself. In still yet another embodiment, the bottom surface (1102) may not contain traction increasing features at all. All such embodiments are bottom surfaces (1102) of tractive pad members (1100) within the scope of this application.

[0162] Figure 17 is a top left perspective view of an exemplary embodiment of a tractive pad member (1100). Figure 17 illustrates an exemplary embodiment comprised of side walls (1 1 10), an interior of the bottom surface (1106), a plurality of stanchion gripping ridges (1 108) that are raised above the inner surface of the side walls to provide friction with the side of a stanchion and an open top through which a stanchion may pass so that the tractive pad member may fit over a stanchion. In another exemplary embodiment of a tractive pad member, the inner surface of the side walls of the tractive pad members might be free of any gripping ridges or other means for increasing friction between a tractive pad member and a stanchion. In still another exemplary embodiment of a tractive pad member, the inner surface of the side walls of the tractive pad members might be comprised of one or more raised features in the form of a dot, an ellipse, a square, a rectangle, a polygon of any shape or an irregular or semi-irregular shape such as those found on the treads of tires or any combination thereof. In yet another exemplary embodiment of a tractive pad member, the inner surface of the side walls of the tractive pad members might be comprised of one or more depressed features in the form of a divot, an ellipse, a square, a rectangle, a polygon of any shape or an irregular or semi-irregular shape such as those found on the treads of tires or any combination thereof. In yet another exemplary embodiment, the inner surface of the side walls of the tractive pad members might be comprised of one or more raised or depressed features in the form of a divot, a dot, an ellipse, a square, a rectangle, a polygon of any shape or an irregular or semi-irregular shape such as those found on the treads of tires or any combination of the preceding. All such embodiments are inner surfaces of the side walls of tractive pad members (1 100) within the scope of this application.

[0163] Definitions.

[0164] For ease of understanding this specification, the following terms are defined as indicated below unless stated otherwise elsewhere. At no time are any of these definitions intended to limit the scope of the claims unless it is expressly adopted in the claim language itself. Similarly, reference to particular examples within each definition are exemplary and non-limiting.

[0165] “Living hinge” is a flexure bearing made from the same material as the two rigid pieces that it connects. One embodiment of a living hinge comprises a purposeful fault line at a predetermined point in a material which will allow the material to bend and not fail after repeated bending . [0166] “Stadium” is a two-dimensional geometric shape constructed of a rectangle with semicircles at a pair of opposite sides. The same shape is known also as a discorectangle, an obround, or a sausage body.

[0167] “Stanchion” is an upright memberthat supports the portable foldable toilet seat; although stanchions are depicted in a non-limiting embodiment as support members that are stadium-shaped when viewed from below; a stanchion could, when viewed from below, be a circle, an ellipse, a square, a rectangle, or a polygon of any shape, and any of the stanchions could be of a different geometric shape from any of the other stanchions or any stanchion could be the same shape geometrically as some or all of the other stanchions; an arch or a partial arch is also a stanchion. Further, although the stanchions are depicted in a non-limiting embodiment as being partially filled with structural support members [(1206), Figure 18], a stanchion could have any internal configuration such as, for example, being solid, hollow or containing a void or multiple voids within its volume. The height of a stanchion (or how tall a stanchion is) is measured from the bottom surface from which the stanchion extends to the highest furthest point on the stanchion from the bottom surface.

[0168] While the present exemplary embodiments are shown in the drawings and fully described above with particularity and detail, it will be apparent to those of ordinary skill in the art that many modifications thereof may be made without departing from the principles and concepts set forth herein, including, but not limited to, variations in size, materials, shape, form, function and manner of operation, assembly, and use.
