Toilet cubicle

Abstract

The invention relates to a toilet cubicle comprising a floor (1), a rear wall (2), and two side walls (3, 4) connected to each other via the rear wall (2), as well as a removable tank (5) arranged therein with an opening (6) for receiving feces. Known toilet cubicles of this type are complex in construction and require costly and time-consuming assembly and disassembly for transport. The objective of designing a toilet cubicle that is inexpensive to manufacture, use, and maintain, as well as easy and space-saving to transport, is achieved by continuously increasing the distance between the two side walls (3, 4) from the floor to the upper edge (7) of the toilet cubicle.

Description

[0001] The invention relates to a toilet cubicle according to the preamble of claim 1.

[0002] For mobile use, primarily outdoors, especially in crisis zones, disaster situations, military applications (e.g., maneuvers, troop movements, and combat operations), humanitarian missions such as in refugee camps, and other large-scale events, there is a significant need for mobile, transportable toilets. These are typically lockable, portable cabins equipped with a toilet seat and a waste collection container. They are usually pre-assembled, with their components expertly bolted together. The units are then transported to the deployment site using delivery vehicles and cranes, and subsequently removed after use. The use of mobile toilets prevents users from defecating openly in nature or in undesignated locations.This ensures a significant contribution to containing infectious diseases.

[0003] The use of mobile toilets is particularly important in disaster and war zones, as well as in humanitarian emergency relief areas where normal water and sanitation services are either nonexistent, severely inadequate, or have failed. Especially in such scenarios, under environmental conditions of poor hygiene and extreme weather, there is a significant risk of epidemics if proper, systematic collection and disposal of feces does not take place.

[0004] A variety of toilet cubicles are available on the market, for example, as described in US 2021 / 0324645 A1 and US 9,765,542 B1, which can also be designed to be disassembled and stacked for easier transport. However, the known toilet cubicles are generally very complex to assemble and disassemble, typically using screw-together mechanisms, and require costly and time-consuming assembly and disassembly for transport. When assembled, they require a considerable amount of space for transport at their point of use.

[0005] The task, therefore, is to design a toilet cubicle in such a way that it is cheap to manufacture, use and maintain, as well as easy and space-saving to transport.

[0006] This problem is solved by the characterizing features of claim 1. Advantageous embodiments can be found in the dependent claims.

[0007] The invention relates to a toilet cubicle comprising a floor, a back wall, and two side walls connected to each other via the back wall, as well as a removable tank arranged therein for collecting feces, wherein the distance between the two side walls increases continuously from the floor to the upper edge of the toilet cubicle. This allows the toilet cubicles according to the invention to be stacked as a whole.

[0008] Preferably, the toilet cubicle is made primarily of high-density polyethylene (HDPE). This results in high resistance and impact strength, as well as high temperature insensitivity and easy transportability due to its low weight.

[0009] Preferably, the removable tank is equipped with a seat and / or an opening for the disposal of feces. This allows the tank to be used as a toilet either while sitting or standing.

[0010] Preferably, the removable tank has a closable opening at its lower end, located near the rear wall, for draining cleaning water after possible internal cleaning of the tank. This allows the tank to be easily emptied from the outside.

[0011] Preferably, the toilet cubicle has a front wall opposite the rear wall, which has a recess in its upper area. This allows the user to extend their legs outwards from the toilet cubicle while seated.

[0012] Advantageously, the toilet cubicle features a lid that pivots at its upper edge. This provides protection from rain, privacy, and theft for the removable tank.

[0013] Preferably, the lid is equipped with a gravity lock, which prevents it from opening only when the lid is at a certain angle. This prevents the lid from opening when the toilet cubicle is stationary.

[0014] Preferably, the opening of the removable tank has a fastening device for a bag located inside the tank to collect the feces. This allows the feces to be removed from the tank quickly and easily.

[0015] Preferably, there is a roller or wheel on each of the lower side walls of the toilet cubicle. This allows the toilet cubicle to be moved.

[0016] Preferably, a roller or wheel with an optimal locking brake is located in the area of ​​the lower rear, which can be pivoted about a vertical axis and rotated about a horizontal axis, thus facilitating the mobility of the toilet cabin when driving.

[0017] Preferably, the toilet cubicle has at least one privacy screen arranged parallel to a side wall and pivotable about a horizontal axis. This provides privacy.

[0018] Preferably, the opening of the removable tank is fitted with a lockable lid. This helps to reduce odors.

[0019] Preferably, the toilet cubicle is stackable with other identical toilet cubicles, with any hinged lids arranged one above the other when open. This results in easy transportability with minimal space requirements.

[0020] Preferably, the toilet cubicle is a converted waste collection container according to DIN EN 840-1. This allows the use of a known basic container.

[0021] An embodiment of the invention is explained in more detail below with reference to the accompanying drawings. These show: Fig. 1 A perspective view of a ready-to-use toilet cubicle according to the invention; The toilet cubicle according to the invention is equipped with side walls 3 and 4, the distance between which increases continuously from the floor 1 of the toilet cubicle to the upper edge 7 of the toilet cubicle. This allows several identical toilet cubicles to be stacked, as is shown in detail below. Fig. 2 A representation according to Fig. 1 with a person using the toilet cubicle and the privacy screens folded down; Fig. 3 The in the Figures 1 and 2Toilet cubicle shown in exploded view and with the lid open; Fig. 4 The tank contained in the toilet cubicle with these additional components in exploded view; Fig. 5 The tank from Fig. 4 in cutaway exploded view; Fig. 6 The toilet cubicle made of Fig. 1 in cutaway view; Fig. 7 A number of stacked, disassembled toilet cabins for transport in a container, e.g. a 40-foot ISO shipping container; Fig. 8 Several operational toilet cubicles according to Fig. 1 with a connecting safety bar as theft protection.

[0022] In Figure 1Figure 1 shows an embodiment of a toilet cubicle according to the invention. This cubicle has a floor 1, a rear wall 2 extending upwards from the floor, and two side walls 3 and 4 connected to each other via the rear wall 2. Within the toilet cubicle and between the side walls 3 and 4, directly above the floor 1, is a removable tank, which is described in the following figures and from which the Figure 1Only the toilet seat 17 is visible. The toilet cubicle also has a front wall 9, which is opposite the rear wall 2, but only in the lower area of ​​the toilet cubicle 1, near the floor 1, connecting the two side walls 3 and 4. In its upper area, the front wall 9 has a recess 10, which extends essentially between the two side walls 3 and 4, but does not quite reach them. The underside of the recess 10 is approximately flush with the toilet seat 17 of the tank located therein, which will be described later.

[0023] The described toilet cubicle has two wheels 14 on its rear side 2, the axes of which run collinearly. One wheel 14 is located on the left side, in the area of ​​the left side wall 3, and the other (not shown) wheel 14 is located in the area of ​​the right side wall 4. These wheels 14 allow the entire toilet cubicle to tilt and be pulled around a horizontal axis like a mobile waste container. On its front wall 9, within a recess extending from the floor 1, there is a rotatable roller 15. This roller is rotatable not only about itself but also about a vertical axis at its bearing, allowing the toilet cubicle to be moved and steered using this roller. Outside the two side walls 3 and 4 are two pivotable privacy screens 16, which are pivotable about the common axis of the wheels 14 and are designed to rotate in the direction of the Figure 1The toilet cubicle is shown in its transport state, swung upwards, and in which it is in Figure 2 The operating state shown can be swung downwards, whereby the upper or front sides of the privacy screens 16 then project beyond the front wall 9 of the toilet cubicle and thus provide lateral privacy, which is necessary in relation to the Figure 2 The person depicted is shown using the toilet cubicle.

[0024] In the Figures 1 and 2 Finally, a lid is shown which is located in the area of ​​the upper edge 7 of the toilet cubicle and which is pivotally attached to the rear wall 2 of the toilet cubicle about an axis 19.

[0025] Figure 3 shows the in the Figures 1 and 2The toilet cubicle is shown with the lid 7 open and in an exploded view. The privacy screens 16 are shown spaced apart from the toilet cubicle, and the lid 11 is open. Also shown is a tank 5 with a toilet lid 17 on its top, the underside of which is designed so that it can be inserted into the body of the toilet cubicle from above (with the lid 11 open) until the toilet lid 17 is approximately flush with the top of the front wall 9, as shown in Figure 1 is shown.

[0026] A more detailed illustration of the construction of Tank 5 shows Figure 4The tank 5 has an opening 6 through which a bag 13 for collecting the excrement is inserted. This bag can be secured in the area of ​​the opening 6 by a fastening device 12. Above this is the plate 18, which can be inserted into the top of the tank 5. A seat 8 in the form of a toilet seat is integrated into the plate 18 and is equipped with a pivoting toilet lid 17. The entire assembly is in Figure 4 shown in exploded view. Furthermore, it shows Figure 5 The same arrangement of tank 5 with opening 6, device 12 and lid 17 including the underlying seat 8, but here without the bag 13. In an alternative embodiment, as is in principle in Figure 5As shown, the tank can also be used without bag 13 if a closable opening for removing the excrement is provided in the area of ​​the rear wall, so that the tank 5 can be emptied to the rear or downwards and through the rear wall 2 via this opening. This is not shown in detail in the drawing.

[0027] Figure 6 Finally, a half-cut view of the toilet cubicle is shown according to Figure 1 . Here it is shown particularly clearly how the tank 5 with the seat 8 and the opening 6 is inserted into the lower area, i.e. directly above the floor 1 between the rear wall 2 and the front wall 9 of the toilet cubicle.

[0028] Figure 7Figure 1 shows several stacked toilet cubicles according to the invention, each of the same design, in a disassembled state. The lids 11 have been removed and placed to the side, as have the tanks 5, the seats 8, and the toilet seats 17. The privacy screens 16 have also been removed and stacked to the side. It is evident that the toilet cubicles can be stacked inside one another due to the increasing distance between the side walls 3 and 4 from bottom to top. The tanks 5 are designed in the same way. They also have an increasing distance between the two (unmarked) side walls from bottom to top and can therefore also be stacked inside one another. The toilet seats 17, the lids 11, the seats 8, and the privacy screens 16 are flat parts that can be placed on top of each other and thus stacked. In this way, it is possible to produce a large number of toilet cubicles of the same design type, e.g.,in an ISO sea container (20 inch or 40 inch), as used in . Figure 7 The design shows that the units can be transported to crisis areas and set up quickly and easily. The toilet cabins can be assembled and disassembled quickly and easily, even by inexperienced users, i.e., by anyone, even in hard-to-reach locations.

[0029] Finally, it shows Figure 8A further development of the invention, which serves to securely connect toilet cubicles of the same design and thus protect them from theft and critical weather conditions, e.g., strong winds. For this purpose, identical toilet cubicles according to the invention are placed next to each other with their rear walls 2, with both resulting pairs of toilet cubicles then being lined up side by side so that the axes 19 of the lids 11 are approximately aligned with each other. A locking bar 21 can then be placed along these axes 19 or parallel to them and connected to the toilet cubicles in a suitable manner, thus providing theft protection and enabling a stable connection of a large number of adjacent toilet cubicles.
