Description

[0001] Portable sanitary unit

[0002] The subject of the invention is a portable sanitary unit, intended in particular for use during mass events.

[0003] From the prior art, portable sanitary units of cuboid construction are known, comprising a sanitary fixture, typically a toilet bowl, washbasin, or shower cubicle.

[0004] Furthermore, from the prior art, keder connections are known, which consist of a rail comprising a longitudinal groove and a slot leading to it, the width of which is smaller than the diameter of the cross-section of the groove. The groove is designed to accommodate the edge of a sheet, typically made of textile material, said edge being attached to a core of synthetic material with a circular cross-section. The sheet of material is connected to rails along its parallel edges. This solution is commonly used in advertising for mounting advertising banners, as well as in tent halls for attaching wall panels.

[0005] From European patent publication EP 2942449 Bl, a keder profile system for a cover, in particular for an awning, is known. The system comprises a profile with a keder rail, and additionally includes a cover with a keder edge, in which a keder - a rod made of synthetic material - is mounted in the rail. The keder is fixed in the edge of the cover using pegs consisting of a head and a shank. The shank is bent in a plane extending through the longitudinal axis of the peg and the longitudinal axis of the fastening screw, and straightens during tightening of the fastening screw.

[0006] From European patent publication EP 2 267 237 Bl, a mechanism for securing a tarpaulin using a keder rail is known, comprising: - a first claw-shaped element for engaging with a first edge-defining portion of the keder rail; - a second claw-shaped element for engaging with a second edge-defining portion of the keder rail, located on the opposite side; - wherein the claw-shaped elements are configured to snap-lock the securing mechanism within the keder rail and are pivotally connected to one another. In the fixed state within the keder rail, the securing mechanism fits tightly against the outer surface of the keder rail.

[0007] From Chinese utility model publication CN 213597572 U, a portable toilet is known, comprising a base, side panels, a top cover, and photovoltaic panels. Furthermore, the toilet is equipped with automatic lighting, switches, and a controller. The side panels are connected to the base and define a toilet compartment. The front side panel includes a door. Furthermore, the portable toilet includes a battery. The photovoltaic panel is located on the upper surface of the cover. Furthermore, an automatic lamp is connected to the cover. Furthermore, the toilet includes a lighting lamp, a washbasin, a faucet, a fresh water tank, a grey water tank, and pumps for supplying water for flushing and hand washing.

[0008] Solutions known from the prior art relating to sanitary units are often used in situations that require additional spatial organization, zoning, and frequently the use of elements providing protection from sun and rain, such as umbrellas or awnings. Additional elements currently in use, such as temporary fencing, barriers, and umbrellas, take up extra space in environments where space is often limited.

[0009] A portable sanitary unit comprising a body that includes a floor, a roof, and vertical side walls, a front wall, and a rear wall arranged between the floor and the roof, further comprising a door in the front wall and a sanitary fixture located inside the body, characterized in that the body comprises, at least at one of its external comer edges, a mounting rail comprising a channel extending along the rail and a slot leading to the channel and parallel thereto, wherein the slot has a width smaller than the diameter of the cross-section of the channel.

[0010] Preferably, the mounting rails are provided at all vertical external comer edges of the body as well as at its upper horizontal external comer edges.

[0011] Further advantages are obtained if the roof comprises a lifting eye at its center on the top side.

[0012] Additional advantages are obtained if the body comprises a supporting frame including four vertical posts connected at the top and bottom by crossbars, and the mounting rails are provided on the outer surfaces of the posts and on the outer surfaces of the upper crossbars.

[0013] Further advantages are obtained if the walls are made of sandwich panels comprising two outer metal sheets with a middle layer of thermal insulation material in between.

[0014] Further advantages are obtained if the roof comprises a photovoltaic panel on its upper surface, and the body contains a battery connected to the photovoltaic panel via an inverter.

[0015] The solution according to the invention enables the organization of space between portable sanitary units without the need for barriers or temporary fencing, which is particularly useful during mass events. Sheets with keder rods at their edges may be freely installed between adjacent sanitary units equipped with keder mounting rails, forming partitions or canopies. The mounting rails of adjacent units may also be used to attach advertising or informational banners. The solution allows for space and time savings related to the installation of additional elements, in particular barriers, informational banners, and advertising banners. The use of sandwich panel walls facilitates maintaining the interior temperature within the comfort range. The use of photovoltaic cells allows for powering both the external and internal lighting of the unit, even in the absence of an external power source. The use of a lifting eye on the roof facilitates repositioning the units and aligning them at distances that allow for the planned installation of keder partitions and canopies. The portable sanitary unit according to the invention is further explained in an embodiment shown in the drawing, in which: Fig. 1 shows the portable sanitary unit in an isometric view; Fig. 2 shows the unit in a front view; Fig. 3 shows the unit in a side view; Fig. 4 shows detail A from Fig. 1 in an enlarged view; Fig. 5 shows detail B from Fig. 1 in an enlarged view; Fig. 6 shows the unit in a sectional view along line A-A of Fig. 2; Fig. 7 shows the unit in a sectional view along line B-B of Fig. 2; Fig. 8 shows detail C from Fig. 6 in an enlarged view; Fig. 9 shows detail D from Fig. 7 in an enlarged view; Fig. 10 shows an assembly of four portable sanitary units arranged in pairs opposite one another, with a canopy mounted between their mounting rails, in a side view; Fig. 11 - a set of units as shown in Fig. 10, in a cross-sectional view along line C-C from Fig. 10; Fig. 12 shows the assembly of units arranged as in Fig. 10, in a top view; Fig. 13 shows an assembly of four units evenly arranged along an arc, with a canopy mounted between them in their mounting rails; Fig. 14 shows the assembly of units as in Fig. 13, in a sectional view along line D-D; Fig. 15 shows an assembly of four units evenly arranged along an arc, with partitions and a canopy mounted between them in their mounting rails.
