FIELD OF THE DISCLOSURE

[0002] The present invention relates to a private toilet system for mounting on a truck type vehicle. In particular, the system herein relates to embodiments that allow for use of a toilet facility for persons driving a truck especially when driving in an area where toilet facilities are not available. Other systems described herein relate to a private toilet system device for a trailer that can be connected to another vehicle.

BACKGROUND

[0003] Toilets are one of the most basic needs of human beings. This basic need can be especially challenging in the trucking industry and among one of the biggest hurdles truck drivers face. America’s trucking industry is the life blood of the U.S economy where nearly 71% of all freight tonnage moves on the backs of these trucks. Moving this much tonnage requires more than 3.6 million heavy duty trucks and over 3.6 million professional truck drivers. Truck drivers are constantly having to deal with deadlines and delays. Delays can be caused by accidents, congestion due to rush hour, road construction, and bad weather. These stressors can cause the truck drivers to stay behind the wheel for hours and continue on the road to their destination in order to make a deadline. Because these deadlines are tight, staying on the road becomes important and bathroom breaks become difficult.

[0004] Truck drivers spend a vast amount of time on the road and at any given time, the personal hygiene and health of these truck drivers is of utmost importance. Though there is a large network of truck stops and rest areas in the United States, the cleanliness and the availability of the toilets at the right time is a significant problem faced by the truck drivers on a regular basis compounded with the other challenges they face. Most often, truck drivers have to wait for long hours at the shipping and delivery facilities with no available restrooms. When there are available facilities, the toilets are frequently unclean and thus unhygienic. With such a basic need of a truck driver unmet where one is required to desist from relieving themselves for a long period of time, physical and health problems arise.

[0005] There are some solutions to these problems which may include aftermarket truck toilet devices equipped to trucks in a variety of manners. Some configurations may include a location within the cabin of the truck, toilets that are deployable from a truck, a generally deployable bathroom unit that may be utilized in trucking, and a toilet integrated into the design of a seat. There are a variety of aftermarket truck toilet designs currently available. While most designs operate with toilet functionality, there are often drawbacks such as locations within the cab rendering foul smells present to the occupants, reduced internal cabin space to accommodate internally located designs, and a lack of secured privacy from other team members within the truck when in use.

[0006] As noted above, it is important that drivers have a means of relief available at any time that the need may present itself, which is clean, private, and hygienic. Existing devices and systems for providing such a basic amenity are unable to fully provide such features. [0007] Accordingly, there is still an unsolved need for a toilet facility technology that may address these and other existing issues.

DETAILED DESCRIPTION [00029] In the Summary above and in this Detailed Description, and the claims below, and in the accompanying drawings, reference is made to particular features (including method steps) of the invention. It is to be understood that the disclosure of the invention in this specification includes all possible combinations of such particular features. For example, where a particular feature is disclosed in the context of a particular aspect or embodiment of the invention, or a particular claim, that feature can also be used, to the extent possible, in combination with and/or in the context of other particular aspects and embodiments of the invention, and in the invention generally.

[00030] The term “comprises” and grammatical equivalents thereof are used herein to mean that other components, ingredients, and steps, among others, are optionally present. For example, an article “comprising” (or “which comprises”) components A, B, and C can consist of (i.e., contain only) components A, B, and C, or can contain not only components A, B, and C but also contain one or more other components.

[00031] Where reference is made herein to a method comprising two or more defined steps, the defined steps can be carried out in any order or simultaneously (except where the context excludes that possibility), and the method can include one or more other steps which are carried out before any of the defined steps, between two of the defined steps, or after all the defined steps (except where the context excludes that possibility).

[00032] The term “at least” followed by a number is used herein to denote the start of a range beginning with that number (which may be a range having an upper limit or no upper limit, depending on the variable being defined). For example, “at least 1” means 1 or more than 1. The term “at most” followed by a number is used herein to denote the end of a range ending with that number (which may be a range having 1 or 0 as its lower limit, or a range having no lower limit, depending upon the variable being defined). For example, “at most 4” means 4 or less than 4, and “at most 40%” means 40% or less than 40%. When, in this specification, a range is given as “(a first number) to (a second number)” or “(a first number) - (a second number),” this means a range whose lower limit is the first number and whose upper limit is the second number. For example, 25 to 100 mm means a range whose lower limit is 25 mm and upper limit is 100 mm.

[00033] Certain terminology and derivations thereof may be used in the following description for convenience in reference only and will not be limiting. For example, words such as “upward,” “downward,” “left,” and “right” would refer to directions in the drawings to which reference is made unless otherwise stated. Similarly, words such as “inward” and “outward” would refer to directions toward and away from, respectively, the geometric center of a device or area and designated parts thereof. References in the singular tense include the plural, and vice versa, unless otherwise noted.

[00034] The term “coupled to” as used herein may mean a direct or indirect connection via one or more components.

[00035] The present disclosure is generally drawn to various embodiments for an independent toilet system that makes it possible to be adapted to be mounted to any large truck, and in particular to a semi-truck. In particular, the one or more non-limiting embodiments for a toilet system enables a large truck to be fitted with the toilet system after market. The toilet system is sized to fit on an exterior of a large truck between the cab and the fifth wheel. Additionally, the toilet system may be securely attached to the large truck with a clamping hardware that would secure and position the toilet system without drilling or welding to the semi-truck. This is advantageous because installing the toilet system to the large truck in such a manner will not compromise the structural integrity of the large truck frame itself. Additionally, the attachment means permits the toilet system to be a removable feature such that the toilet system is not permanently installed and may be removed when needed, again without any damage to the large truck.

[00036] In addition to the use of an independent toilet system with a semi-truck, it would be desirable to have the same system available to those who may travel on the road. For example, it may be beneficial for a camping trip to provide a private and fully functional toilet for use. In particular, a toilet system would be provided on a trailer which may be directly manufactured onto the trailer or be mounted onto the trailer wherein the trailer is connected to a hitch of any vehicle and towed.

[00037] Accordingly, the one or more non-limiting embodiments provided below describe a toilet system that may be mounted onto a large truck. The embodiments provided herein may be used for multiple vehicle types, wherein a toilet system may be provided on a trailer to be hitched to a vehicle. Further details are provided below with reference to the Figures. It is also to be understood that because the toilet system described in the present disclosure is an independent system which may function on its own, the toilet system may be used anywhere independent of any vehicle.

[00038] Turning to the Figures, FIGS. 1 to 8 are illustrations depicting a toilet system 100 which is an example of an independent system for readily providing a private enclosed structure to be used for meeting toilet needs, for example, mounted to an exterior of a large truck and used by a truck driver while on the road. FIG. 8 illustrates one such toilet system 100 mounted to an exterior of a large truck 500. In one or more non-limiting embodiments, the toilet system 100 comprises of a fully enclosed compartment 101 having one or more doors 108 that allow access to an interior of the enclosed compartment 101. The toilet system 100 also comprises of a toilet 110 operatively connected to a clean water tank 112 and a waste tank 114. The toilet system 100 further comprises of a curtain panel 120, movable along a guide channel 122, and stored within a storage channel 124. The toilet system 100 may also comprise of an electronic display panel 130 which monitors and controls several electrical features integrated into the toilet system 100. In order to supply power to the electronic display panel 130 and control the several electrical features, a solar panel 150 may also comprise the toilet system. Additional features, such as a storage enclosure 160, lighting 162, a toilet paper holder 164, and a fixed enclosure 170 for containing a battery (not shown) and other electronics (not shown) may also comprise the toilet system 100.

[00039] With reference to FIGS. 1 and 2, an exterior of the toilet system 100 is shown with the one or more doors 108 of the enclosed compartment 101 closed. More specifically, the enclosed compartment 101 is shown to comprise of a platform 102, a roof 103, a back wall 105 (see, FIGS 3 and 4), a left side wall 106, a right side wall 107, and the one or more doors 108. In the figures, the one or more doors 108 are shown to be comprised of two doors which may be hingedly connected to the left side wall 106 and the right side wall 107, and which open to allow access to the interior of the enclosed compartment 101. In this configuration, the two doors 108 are provided with a handle 109 which may be gripped to open or close the doors 108. The handle 109 may be of a type that locks. Consequently, the toilet system 100 may be used by a person with a means to unlock the two or more doors or by someone else with permission of the person with the means to unlock. The handle 109 with the lock also ensures that the one or more doors 108 remain closed while a vehicle that the toilet system 100 is mounted to is moving.

[00040] The one or more doors 108 may also include a mechanical door closing device which is responsible for ensuring that the one or more doors 108 are closed properly and in a controlled manner without slamming. In the FIGS. 3 to 7, the mechanical door closing device is depicted as a hydraulic door closer 108a which is installed on both doors 108. It is to be understood that other mechanical door closing devices that close doors in a controlled manner may also be used. It is also to be understood that the one or more doors 108 may be provided without a mechanical door closing device.

[00041] As seen in the Figures, the platform 102 provides a base onto which most of the components comprising the toilet system 100 are configured or integrated onto. The platform 102 confers another advantage where the toilet system may be an independent unit capable of being placed anywhere and function independent of any other structural feature not part of the toilet system 100. The platform 102 is designed such that a portion of it extends past the one or more doors 108 when in a closed position. In one or more non-limiting embodiments, the platform 102 may be fashioned from a strong material such as a metal and configured in a two-dimensional shape wherein the portion that extends past the closed one or more doors 108 is in a shape of a semi-circle.

[00042] When the one or more doors 108 are open, the interior of the toilet system 100 is accessible to someone for toilet use. The toilet system 100 is generally provided for use in an outdoor environment, for example, mounted to an exterior of a semi-truck. Thus, the toilet system 100 comprises of at least one curtain panel 120 which may be used to provide privacy to a person using the toilet system 100. In the non-limiting embodiment shown in FIGS. 3-7, a pair of curtain panels 120 comprise the toilet system 100 to confer privacy during use. In this configuration, the pair of curtain panels 120 may be provided with one on each of the left side wall 106 and the right side wall 107 such that the curtain panels 120 may be pulled toward a front of the toilet system 100 to provide adequate privacy. It is to be understood that one curtain panel 120 may also comprise the toilet system 100, wherein the one curtain panel may be provided on either a left side wall 106 or a right side wall 107 and capable of being pulled fully from one side to the other. The one or more curtain panels 120 may be of a height that provides adequate privacy during toilet use. As best seen in FIGS. 6 and 7, the one or more curtains 120 are shown to have a height which is relatively half of a height of the enclosed compartment 101. It is to be understood that the height of the one or more curtains 120 may be relatively equal to the height of the enclosed compartment 101.

[00043] In the one or more non-limiting embodiments shown in FIGS. 3-7, the pair of curtain panels 120 are integrated onto the guide channel 122 which is configured onto the platform 102. The guide channel 122 is shown to be integrated along a perimeter of a bottom surface of the platform 102. The pair of curtain panels 120 are fashioned with any suitable material which is weather resistant and wear and tear resistant, including and not limited to durable fabric material, plastic, or metal or a combination of materials. The curtain panels 120 may be configured such that the curtain panels 120 are adjoined to a rail system 126 to allow the curtain panels 120 to slide open and closed in an accordion like motion. The rail system 126 is integrated into the guide channel 122 which facilitates the sliding movement between the open position and the closed position. It is to be understood that the curtain panel may be constructed in any suitable configuration to slide along the guide rail 122 to open and close.

[00044] In one or more non-limiting embodiments, the curtain panel 120 is stored within the storage channel 124 when not in use. As clearly seen in FIGS. 3 and 4, the storage channel 124 is provided along each of the left side wall 106 and the right side wall 107 such that the curtain panels 120 may be stored within their respective storage channels 124 when not in use and when the one or more doors 108 are moved to the closed position. The storage channel 124 may be described as a vertically extending gutter along the left side wall 106 and the right side wall 107. The benefits of the storage channel 124 not only include a means to store the curtain panel 120 when not in use but may also include protecting and securing the curtain panel 120 when in a closed position.

[00045] With reference to FIGS. 3 and 4, the interior of the toilet system 100 is shown. As can be seen, the interior of the toilet system 100 comprises of the toilet 110 arranged between the storage enclosure 160 and the fixed enclosure 170. In the illustrated form, the toilet 110, storage enclosure 160, and the fixed enclosure 170 are in line and arranged relatively evenly with each other such that they conveniently form a bench, however, may also take any convenient form. The toilet 110, the storage enclosure 160, and the fixed enclosure 170 are configured onto the platform 102. In a preferred form, the toilet 110 is of a type that is fully functional such that the toilet 110 has a fill, flush, or rinse capability. The toilet 110 may also include a bidet feature (not shown). It is to be understood that alternatively any form of toilet may be used, including and not limited to a non-flushing kind and/or not provided with a bidet feature. Any functions of the toilet 110 may be controlled electronically via the electronic control assembly 130 (discussed below) or alternatively may have manual function capabilities such as a manual flush. Advantages of the toilet system 100 comprising a functional toilet 110 with flushing capability include, but are not limited by, inner sides of the toilet being cleansed with each flush, flushing or removing waste and sending it into the waste tank, and further reduction in odor.

[00046] The toilet 110 may include a lid 110a that can be placed over an opening in the toilet 110 and simultaneously provide a convenient bench with the storage enclosure 160 and the fixed enclosure 170. In a preferred non-limiting embodiment, the toilet 110 comprises of a heated seat. The benefit of the heated seat being that because the toilet system 100 is placed in an outside environment the toilet system is exposed to varying temperatures, and thus in cold temperatures the seat of the toilet 110 may be heated prior to use. It is also to be understood that in alternate embodiments, the toilet 110 may be comprised of a seat that is not electrically heated.

[00047] In one or more non-limiting embodiments illustrated in FIGS. 3 to 7, the toilet 110 is operatively connected to the clean water tank 112 and the waste tank 114. One or more electrically controlled valves (not shown) ensure the toilet 110 functions properly where the flow of water in from the clean water tank 112 and out to the waste tank is controlled appropriately.

[00048] The clean water tank 112 and the waste tank 114 may each be equipped with a temperature control unit (not shown) which is electronically controlled via the electronic control assembly 130 (discussed below). The temperature control unit includes a temperature sensor, a heating element, and a cooling system which are contained within the clean water tank 112 and the waste tank 114 to regulate the temperatures of the clean water and the waste removed from the toilet 110, respectively. Regulating the temperature of the clean water and the waste stored in their respective tanks serves several purposes including and not limited to preventing freezing in cold weather, preventing heating in warm weather, maintaining odor control, ensuring system integrity, and other issues related to extreme or fluctuating temperatures.

[00049] The clean water tank 112 and the waste tank 114 may each be equipped with a level sensor (not shown) which provides for a means to easily determine the level of clean water and waste in their respective tanks. The level sensors help visually identify when the clean water tank 112 may need to be refilled and the waste tank 114 may need to be emptied. In one or more non-limiting embodiments, the level sensors may be provided within each of the clean water tank 112 and the waste tank 114 and a level of each tank may be indicated on the electronic display panel 130 (discussed below). For example, the electronic control assembly 130 may include a sequence of LED lights which indicate the level of clean water or waste by a number of LEDs lit up for each. In alternate embodiments, the level sensors may be provided within each of the clean water tank 112 and the waste tank 114 and a level of each tank may be indicated on the respective tanks. For example, similar to the above example, the clean water tank 112 and the waste tank 114 may each be configured with a sequence of LED lights which indicate the level of clean water or waste in their respective tanks by the number of LEDs lit up. In a further embodiment, the level of clean water and waste within the clean water tank 112 and the waste tank 114, respectively, may be visually determined by providing a view into each of the tanks through a clear section on each of the clean water tank 112 and the waste tank 114.

[00050] The clean water tank 112 may be of a size that can fit within the interior of the toilet system 100. In one or more embodiments, the clean water tank 112 may be within the non-limiting range of six to ten gallons. As illustrated in the figures, the clean water tank 110 is located within the interior of the toilet system 100 and connected to the back wall 105 of the enclosed compartment 101 relatively close to the toilet 110. It is also to be understood that alternatively the clean water tank 112 may be configured into the back wall 105 of the enclosed compartment 101 such that the clean water tank 110 is a part of the back wall 105. The clean water tank 112 is filled with clean water through a fill tube 113 which extends from the clean water tank 112 and exits out through the left side wall 106 and wherein a cap 113a closes an end of the fill tube 113 that sits outside of the enclosed compartment 101. To fill, the cap 113a may be removed and the clean water tank 112 may be filled by any means, such as placing a water hose into the fill tube 113 which is connected to the clean water tank 112. Once filled, the water hose may be removed and the cap 113a replaced onto the end of the fill tube 113 that sits outside of the enclosed compartment 101. [00051] The waste tank 114 is provided as a storage tank to collect any waste that is flushed from the toilet 110 and may be provided on a bottom surface of the platform 102. In one or more non-limiting embodiments, the waste tank 114 may be configured onto the bottom surface of the platform 102 and having a capacity of ten to fourteen gallons. A drain 115 may be configured onto the waste tank 114 to provide a means to empty and clean the waste tank 114. As shown in the figures, the drain may be configured onto a side of the waste tank 114 for easy access. The waste tank 114 may be configured in a similar shape to the platform 102 such as to provide a seamless appearance. An interior of the waste tank 114 may be configured with the interior of the waste tank 114 angled toward the drain 115 such that the waste collecting in the waste tank 114 gravitationally moves toward the drain 115. The waste tank 114 is emptied in a similar fashion to a recreation vehicle (RV) waste tank wherein a drain hose (not shown) is attached to the drain 115 on the toilet system and the waste tank is allowed to drain through the drain hose at an appropriate sewer line or dumping station. The waste tank 114 may be rinsed clean and drained.

[00052] As mentioned earlier, additional features may also comprise the toilet system 100 including and not limited to the solar panel 150, the storage enclosure 160, the fixed enclosure 170, the lighting 162, and the toilet paper holder 164. The solar panel 150 may be provided on an outside of the enclosed compartment 101, and preferably mounted to the roof 103 with an adjustable mount (not shown) such that a tilt of the solar panel 150 may be adjusted to maximize exposure to the sun. The solar panel 150 provides an option for charging the batteries when a vehicle’s power is not available.

[00053] The fixed enclosure 170 is provided to contain the battery that powers any electronics comprising part of the toilet system 100. For example, in one or more non-limiting embodiments, the toilet 110 may be flushed electronically through the electronic control assembly 130 which contains most of the control features of the toilet 110. In this configuration, the toilet system 100 may be powered by the battery stored in the fixed enclosure 170. Further, any electronics may also be stored in the fixed enclosure 170. The lighting 162 is configured on the interior of the enclosed compartment 102 to provide light when need for using the toilet system. In the one or more non-limiting embodiments shown in FIGS. 3 to 7, the lighting 162 may be configured as an overhead lighting wherein the lighting 162 is installed on an interior facing side of the roof 103 of the enclosed compartment 101. The lighting 162 may be controlled through the electronic control assembly 130 or alternatively may be controlled through a manual switch (not shown) or turned on when the one or more doors 108 of the enclosed compartment 102 are opened. The toilet paper holder 164 is configured on a left side wall 106 or alternatively on a right side wall 107 for holding a toilet paper roll for easy access. The storage enclosure 160 is provided to allow storage of items such as and not limited to cleaning supplies, toilet paper, and other toilet necessities.

[00054] In one or more non-limiting embodiments, the electronic control assembly 130 also comprises part of the toilet system 100 and provides an electronic means of controlling most all functions of the toilet system 100. In referring to FIG. 9, a block diagram depicts the electronic control assembly 130 and the other features comprising the toilet system 100 that the electronic control assembly 130 is in communication with. The electronic control assembly 130 is an interface to control the various functions of the toilet system 100 by receiving and interpreting data to monitor and perform the designated tasks for the following: the toilet 110; the lighting 162; the clean water tank 112; the waste tank 114; the solar panel 150; the battery in the fixed enclosure 170; an in-cab control/monitor assembly 180; and a door open sensor 139. It is to be understood that any other electronic assemblies beneficial to the toilet system 100 may be connected to the electronic display 130.

[00055] Referring to both FIGS. 9 and 10, each of the various features comprising the toilet system 100 and their respective tasks are depicted along with the electronic control assembly 130. The electronic control assembly 130 includes a microcontroller (MCU) and interfaces to all other functional features to support overall operation of the toilet system 100. The electronic control assembly 130 provides an interface which may contain a plurality of switches and a plurality of indicators which provide a local user interface on the interior of the enclosed compartment 101. As best seen in FIG. 10, some examples of the switches and the indicators include and are not limited to, a light switch to turn the lighting 162 on and off, a seat heat switch for the toilet 110, a toilet fill switch to fill the toilet 110 with water prior to use, a toilet flush switch to rinse and flush the toilet 110, a first series of LEDs specifically to indicate the level of water in the clean water tank 112, and a second series of LEDs specifically to indicate the level of waste accumulated in the waste tank 114.

[00056] The block diagrams in FIGS. 9 and 10 also show the in-cab control assembly 180 which is remotely connected to the electronic control assembly 130. The in-cab control assembly 180 is an interface panel provided for a driver of a vehicle and may be located inside a vehicle, such as a cab of a truck to which the toilet system 100 is mounted on. The in-cab control assembly 180 contains a status display to show a driver the status of the toilet system 100, such as and not limited to levels and temperatures in the clean water tank 112 and waste tank 114, the battery status, and other relevant indicators. The in-cab control/monitor assembly 180 may also contain switches which provide inputs to the electronic control assembly 130 for remote operation of the lighting 162, heating the seat of the toilet 110, adjusting the temperatures in the water tank 112 and the waste tank 114, and other relevant functions that can be controlled remotely. An alternative option for the in-cab control/monitor assembly 180 is to use an OLED or LCD type display with touch overlay instead of discrete indicators and switches. The advantage of the in-cab monitor assembly 180 is that it allows a driver to monitor some conditions of the toilet system 100 from within the vehicle rather than having to exit the vehicle and check the conditions. It may be beneficial in a situation where the vehicle is driving through an extreme weather condition, for example the temperature is either very hot or very cold, and with the in-cab monitor assembly 180, the driver may be alerted immediately that the temperatures in the clean water tank 112 or the waste tank 114 need to be addressed.

[00057] Referring to FIGS. 11 through 14, an alternate non-limiting embodiment of a toilet system is depicted and referred to as toilet system 200. The toilet system 200 is designed to be used on a trailer 600 wherein the trailer 600 is hitched to a back of a vehicle. The toilet system 200 may be a useful addition for vehicles with limited living facilities where people can camp or have to stay away from toilet and shower amenities for a period of time. The toilet system 200 is designed to be directly installed on a trailer during manufacturing or alternatively may be installed post manufacturing. It is also to be understood that the toilet system 200 is an independent system and may be used anywhere without mounting to a trailer or another vehicle.

[00058] In this non-limiting embodiment, the toilet system 200 is comprised of most of the same features as the toilet system 100 discussed above. The toilet system 200 comprises of a fully enclosed compartment 201 having one or more doors 208 with a handle 209 that allows access to an interior of the enclosed compartment 201.

The platform 202 is configured similarly to the toilet system 100 which provides a base onto which most of the components comprising the toilet system 200 are configured or integrated onto. In FIGS. 11 through 13, the one or more doors 208 are shown to be comprised of two doors which may be hingedly connected to the left side wall 206 and the right side wall 207, and which open to allow access to the interior of the enclosed compartment 201. In this configuration, the two doors 208 are provided with a handle 209 which may be of a type that locks. Consequently, the toilet system 200 may be used by a person with a means to unlock the two or more doors or by someone else with permission of the person with the means to unlock.

[00060] The one or more doors 208 may also include a mechanical door closing device and depicted in the figures as a hydraulic door closer 208a which is installed on both doors

208. It is to be understood that other mechanical door closing devices that close doors in a controlled manner may also be used. It is also to be understood that the one or more doors 208 may be provided without a mechanical door closing device.

[00061] As with the toilet system 100, the one or more doors 208 open to the interior of the toilet system 200 and is accessible to someone for toilet or shower use. The toilet system 200 comprises of one or more curtain panels 220 to provide privacy during use. Similar to the toilet system 100, a pair of curtain panels 220 comprise the toilet system 200 which may be provided with one on each of the left side wall 206 and the right side wall 207 such that the curtain panels 220 may be pulled toward a front of the toilet system 200 to provide adequate privacy. It is to be understood that only one curtain panel 220 may also comprise the toilet system 200, wherein the one curtain panel may be provided on either a left side wall 206 or a right side wall 207 and capable of being pulled fully from one side to the other. The one or more curtain panels 220 may be of a height that provides adequate privacy during toilet use and shower use. As best seen in FIG. 14, the one or more curtains 220 are shown to have a height which is relatively more than half of a height of the enclosed compartment 201. It is to be understood that the height of the one or more curtains 220 may also be relatively equal to the height of the enclosed compartment 201. Also shown in FIG. 14, a bottom end of the curtain sits above the platform 202 such that there is some space for water used during a shower to spray out.

[00062] The one or more of curtain panels 220 are integrated onto the guide channel 222 which is configured onto the platform 202. The guide channel 222 is integrated along a perimeter of a bottom surface of the platform 202. The one or more curtain panels 220 may be configured such that the one or more curtain panels 220 are adjoined to a rail system 226 to allow the one or more curtain panels 220 to slide open and closed in an accordion like motion. The rail system 226 is integrated into the guide channel 222 which facilitates the sliding movement of the one or more curtain panels 220 between the open position and the closed position. It is to be understood that the one or more curtain panels 220 may be constructed in any suitable configuration to slide along the guide rail 222 to open and close.

[00063] Similar to the toilet system 100, the one or more curtain panels 220 are stored within the storage channels 224 that may be described as vertically extending gutters provided along each of the left side wall 206 and the right side wall 207. The one or more curtain panels 220 may be stored within their respective storage channels 224 when not in use or when the one or more doors 208 are moved to the closed position.

[00064] The interior of the toilet system 200 comprises of the toilet 210 arranged between the fixed enclosure and the shower area 290. In the illustrated form, the toilet 210 and the fixed enclosure 270 are in line and arranged relatively evenly with each other such that they conveniently form a bench, however, may also take any convenient form. In a preferred form, the toilet 210 is of a type that is fully functional such that the toilet 210 has a fill, flush, or rinse capability. The toilet 210 may also include a bidet feature (not shown). It is to be understood that alternatively any form of toilet may be used, including and not limited to a non-flushing kind and/or not provided with a bidet feature. Any functions of the toilet 210 may be controlled electronically via the electronic control assembly (not shown, but similar to the electronic control assembly 130 of the toilet system 100) or alternatively may have manual function capabilities such as a manual flush.

[00065] The toilet 210 may include a lid 210a that can be placed over an opening in the toilet 210 and simultaneously provide a convenient bench with the fixed enclosure 270. Maintaining the similarity with the toilet system 100, the toilet 210 of the toilet system 200 comprises of a heated seat. It is also to be understood that in alternate embodiments, the toilet 210 may be comprised of a seat that is not heated.

[00066] The toilet 210 is operatively connected to the clean water tank 212 and the waste tank 214. One or more electrically controlled valves (see block diagram FIG. 10, Valve Actuator in Toilet 110) ensure the toilet 210 functions properly where the flow of water in from the clean water tank 212 and out the waste tank 214 is controlled appropriately.

[00067] The clean water tank 212 and the waste tank 214 may each be equipped with a temperature control unit (not shown) which is electronically controlled via the electronic control assembly (see electronic control assembly 130 discussed above in FIGS. 9 and 10). The temperature control unit includes a temperature sensor, a heating element, and a cooling system which are contained within the clean water tank 212 and the waste tank 214 to regulate the temperatures of the clean water and the removed waste in their respective tanks. Regulating the temperatures of the clean water and the waste stored in their respective tanks serves the same purposes as discussed above in respect to the toilet system 100.

[00068] The clean water tank 212 and the waste tank 214 may each be equipped with a level sensor (not shown) to easily determine the level of clean water and waste in their respective tanks. The configurations and functions of the level sensors are discussed above in reference to the toilet system 100 and are generally the same in the toilet system 200. In one or more non-limiting embodiments, the level sensors may be provided within each of the clean water tank 212 and the waste tank 214 and a level of each tank may be indicated on the electronic display panel.

[00069] The clean water tank 212 may be of a size that can fit within the interior of the toilet system 200 and may be within the non-limiting range of six to ten gallons. Similar to the previous embodiment of the toilet system 100, the clean water tank 212 is also located within the interior of the toilet system 200 and connected to the back wall 205 of the enclosed compartment 201 relatively close to the toilet 210. It is also to be understood that alternatively the clean water tank 210 may be configured into the back wall 205 of the enclosed compartment 201 such that the clean water tank 210 is a part of the back wall 205. The clean water tank 212 is filled with clean water through a fill tube 213 which extends from the clean water tank 212 and exits out through the left side wall 206 and wherein a cap 213a closes an end of the fill tube 213 that sits outside of the enclosed compartment 201.

[00070] The waste tank 214 is provided as a storage tank to collect any waste that is flushed from the toilet 210 and water that is drained through the shower drain. In the non-limiting embodiment shown in FIGS. 11 through 14, the waste tank 214 may be provided on a bottom surface of the platform 202 by being configured onto the bottom surface of the platform 202. In alternate non-limiting embodiments, the waste tank may be provided on a bottom surface of the trailer that the trailer toilet system is manufactured onto. In any of these embodiments, the waste tank 214 may have an increased capacity of thirty to forty gallons to accommodate for waste increased due to use and the combination of clean water tank 212 and the shower water tank 294. A drain (not shown) similar to the toilet system 100 drain (see FIG. 2, drain 115) may be configured onto the waste tank 214 to provide a means to empty and clean the waste tank. The drain may be configured onto a side of the waste tank for easy access. An interior of the waste tank may be configured such that allows for easy drainage and cleaning with the interior of the waste tank angled toward the drain such that the waste collecting in the waste tank gravitationally moves toward the drain. The waste tank is emptied in a similar fashion as discussed above for the toilet system 100. [00071] The trailer toilet system 200 also comprises of the lighting (not shown), the fixed enclosure which contains the battery and electronics that power the toilet system 200, and the toilet paper holder 264. These components are similar to the toilet system 100 and discussed above in respect to the toilet system 100.

[00072] In addition, the toilet system 200 comprises of a shower area 290 which includes and is not limited to the divider wall 291, the fold down seat 292, the showerhead 293, the shower water tank 294, and a shower drain 295. The divider wall 291, as seen in FIGS. 11 and 12, is a fold out section that is hingedly connected to the back wall 205 on the interior of the enclosed compartment 201. The divider wall 291, in a closed position, abuts and rests parallel against the back wall 205. In an open position, the divider wall 291 is turned to rest perpendicularly to the back wall 205, such that the toilet 210 is shielded from the shower area 290. In the open position of the divider wall 291, the fold down seat 292 may be lowered from the divider wall 291 for a person to use if they desire to sit and shower. The fold down seat 292 is hingedly connected to the divider wall 291 on a side that faces the shower area 290 when the divider wall 291 is in the open position.

[00073] The showerhead 293 is integrated into the roof 203 on the interior of the enclosed compartment 201. The showerhead 293 may be any reasonable type including and not limited to a standard fixed, a handheld, a dual, a rainfall, and others. The showerhead 293 is supplied with water from the shower tank 294. The shower water tank 294 is placed on a top of the roof 203 on an exterior of the enclosed compartment 201. The shower water tank 294 capacity may be in the range of twenty -five to thirty gallons and once placed on the top of the roof 203 the water will be gravity fed to the showerhead 293. The showerhead 293 may have a pipe 296 that extends into the roof 203 and has an opening at a top which may be closed with a cap 296a. The shower water tank 294 may have an opening (not shown) that corresponds to the opening with the cap 296a which leads to the showerhead 293. When the shower water tank 294 is placed on the roof 203, the opening in the shower water tank 294 is placed over the showerhead 293 pipe opening once the cap 296a is removed, such that water from the shower water tank 294 may gravity flow through the pipe 296 and into the showerhead 293.

[00074] The shower water tank 294 also comprises of a fill opening (not shown) that includes a cap, wherein the cap may be removed and the shower water tank is filled with water. Advantageously, the shower water tank 294 is sized such that it may be stored in the interior of the enclosed compartment 201, preferably in the shower area during travel or when the toilet system 200 is not in use, as shown in FIG. 12. The shower water tank 294 is generally stored when empty. To use, the shower water tank 294 is removed from within the interior of the enclosed compartment 201 and placed on the roof 203 on the exterior of the enclosed compartment 201 and filled with water through the fill opening.

[00075] The shower drain 295 is configured onto the platform in the shower area 290. The shower drain 295 is connected to the waste tank 214 such that water used during a shower may drain into the waste tank 214. The platform 202 in the shower area may be tapered toward the shower drain 295 such that most of the water will flow toward the shower drain 295 and drain into the waste tank 214.

[00076] The electronic control assembly (not shown) of the toilet system 200 is similar to the toilet system 100 electronic control assembly which has been described above in FIGS. 9 and 10. One difference being that the shower water tank 294 does not have an electronic interface with the electric control assembly but may have alternate means to determine water level such as a visual indicator on the shower water tank 294 itself. [00077] Accordingly, the present description provides for various embodiments for a toilet system that may be mounted on an exterior of truck. The present disclosure also provides for a trailer toilet system that may be manufactured onto or alternatively be mounted onto a trailer that may be hitched to a vehicle and towed.
