Description

DESCRIPTION

Transportable sanitary unit

BACKGROUND OF THE INVENTION

The invention relates to a transportable residential space, particularly equipped as a sanitary unit.

Residential spaces, including service spaces, which can be transported, assembled and used as units, are generally known in various guises, such as office unit, sanitary unit (toilet unit, shower unit), kitchen unit, bedroom unit, etc. The dimensions of such units vary greatly. In addition, they have different ways of handling, such as the use of a hook, a tilting mechanism or corner fittings (known from ISO standard containers).

When transporting these residential units, all their contents are transported, not only the optional inventory, but mainly the air. There are fully collapsible residential units, but inventory cannot be transported with them.

Transportation costs have increased considerably in recent years. Therefore, the transportation of residential units is also becoming more expensive. Since the demand for residential units, especially for temporary use, continues to increase, for example, for events, construction sites, humanitarian aid, catastrophes, peacekeeping missions, war missions, post-war reconstruction, etc., the need for transport in this area will continue to grow. WO 02/17764 A1 discloses a transportable unit for forming a residential space in the form of a right parallelepiped, provided with a bottom and a cladding, and vertical walls extending between them, which walls can be converted between a retracted and a retracted transport position. an extended operating position, in which the unit has a height that is greater than the height in the retracted transport position, in which the unit is stackable and equipped as a sanitary unit having a series of toilet bowls, in in which the vertical walls form interior partitions/walls to protect the toilet bowl sub-spaces, in which the bottom is part of a lower section of the unit and the lining is part of an upper section of the unit. Documents WO 02/103138 A1 and US 2005/0284035 A1 disclose other transportable units that form part of the state of the art.

SUMMARY OF THE INVENTION

It is an object of the invention to provide a residential space designed as a sanitary unit that can be transported efficiently.

It is an object of the invention to provide a residential space designed as a sanitary unit that is suitable for the efficient transportation of groups.

It is an object of the invention to provide a residential space designed as a sanitary unit that is advantageous in terms of the transport energy required.

It is an object of the invention to provide a residential space designed as a sanitary unit that is suitable for temporary deployment at a site of use and can be advantageously transported to and from it.

According to the invention there is provided a transportable unit according to claim 1 for forming a residential space in the form of a right parallelepiped, provided with a bottom and a lining, and walls extending between them, which walls can be converted between a position -particularly retracted- and an operative position -particularly extended-, in which the unit has a greater height, in which the unit is equipped as a sanitary unit having a series of toilets, urinals and/or showers. In this way, one or more toilet units can be advantageously transported to and from a site of use, such as an event site, and still provide an at least substantially complete toilet facility at that location.

The bottom can provide space for a common drain pipe for toilet bowls, urinals and/or showers. In a water saving embodiment, the drain pipe is connected to a vacuum drain system.

In one embodiment, the walls may become telescopic.

The walls may comprise a top wall attached to the liner and a bottom wall attached to the bottom, wherein the top wall and bottom wall are preferably approximately similar in height. In one embodiment, the top wall and the bottom wall can slide vertically relative to each other. In another embodiment, the top wall and the bottom wall can slide past each other in a vertical direction, where the bottom preferably forms part of a lower section of the unit and the liner forms part of an upper section of the unit. unit that can move in a vertical direction with respect to the other.

The walls may form one or more side walls of the unit.

The walls can form interior partitions/walls to protect sub-spaces for toilets and/or showers.

One or more side walls can be provided with doors for each subspace.

In one embodiment, the side walls form part of a subspace partition to the outside.

In one embodiment, the subspaces have been formed by pairs of boxes, each of which having three vertical walls, on both sides of the subspace and facing the entrance of the subspace, as a rear wall, which walls are preferably formed as a unit, such as polyester, in which both boxes are open on the input side and on opposite sides and in which the upper box, which forms part of the upper section of the unit, is oriented vertically inverted with respect to the lower box which is part of the lower section. Both boxes of a pair have dimensions such that, when converted, their vertical walls can slide vertically along each other.

In one embodiment, an inner wall forms a dividing wall between two series of urinals and/or toilet bowls, the individual branch lines (bowls or urinals) of which to the drain pipe are at least partially incorporated in the dividing wall. The partition wall may have a lower partition wall and an upper partition wall, wherein the lower partition wall is divided into a first part and a second part supporting each of the toilet bowls or urinals of a respective series, and between they define a housing space for the upper dividing wall. The upper partition wall can be completely free of fluid pipes, each part of the lower partition wall provides support for the bowls or urinals, respectively, of both series and offers space to the corresponding individual branch line for each bowl or urinal and together with the other part of the lower dividing wall it offers space to the upper dividing wall in the transport position.

Toilet bowls, urinals and/or shower heads are preferably arranged in the section of the unit comprising the bottom so that the piping system can remain in place during conversion activities.

The sanitary residential unit in the transport position is preferably half the standard height of a standard shipping container. Since in the lowered, particularly retracted position, the sanitary residential unit is half the standard height, two such sanitary units, in the lowered, particularly retracted position, placed one above the other, will correspond in terms of height to a container non-folding standard (ISO) standard height. In this way, two retracted sanitary residential units can be moved within the same transport volume. Two retracted sanitary residential units take up as much space as a normal standard container. Due to the half height of the sanitary residential spaces during transport, the sanitary inventory can also remain at least substantially in the residential space and there is room to transport other goods that are required at the destination, such as walkways, barriers.

In the operative position, the sanitary residential unit can have a full standard height of a standard container, so that in a multiple transport with an odd number of units a standard height can always be provided if one unit is not retracted. Then 1 foot = 30.48 cm and 1 inch = 2.54 cm.

The standard height will particularly be the height of a 20ft TEU container, 40ft TEU container or 45ft High Cube container which are widely used today. These measure 2.5 meters, 2.5 meters and 2.5 meters respectively. These are standard containers according to the ISO standard.

Adaptation to standard transport facilities for freight containers is increased if the length and width of the sanitary unit are equal to the length and width, respectively, of a 20-foot TEU container, a 40-foot TEU container or a 45-foot High Cube container, i.e. 20'x8', 40'x8' and 45'x8', respectively. If the length and width of the sanitary unit are equal to the length and width, respectively, of a 20-foot TEU container and the height in the transport position is equal to half the height of a 20-foot High Cube container, 45 feet, an advantageous adaptation to the means of transport is obtained, in particular to trucks, which are usually adapted to the 20 feet of the TEU, and in the operative position a greater overlap between the parts of the unit can be realized. slide into each other during conversion.

The handling of the unit according to the invention is further improved if it is provided with ISO corner fittings at the corners, preferably at all corners.

In one embodiment, the upper side wall and the lower side wall of at least one side wall comprise a door top part and a door bottom part, respectively, to form an entrance door to the residential space in the operative position, in which the upper part of the door and the lower part of the door can be hinged about a vertical hinge center line and are connected to the cladding and to the lower part by an upper hinge and a lower hinge, respectively, in particular to a frame section therefor, in particular a horizontal frame section, in which the hinge center lines of the upper hinge and the lower hinge are aligned with each other. This increases design freedom for the relative position of the upper side wall and the lower side wall, since it is not necessary to attach hinges to them that are aligned with the center lines of the hinges. The upper part of the door and the lower part of the door can be provided with parts of connection to be mutually connected in the operative position, so that a door is obtained which can be operated as a unit. In one embodiment, the upper part of the door and the lower part of the door can slide vertically into each other. In another embodiment, the upper part of the door and the lower part of the door can slide along each other in the vertical direction.

In one embodiment the doors are removable and in the transport position of the unit they can be stored in the unit, so that after conversion of the unit in the operative position they can be hung in the desired places.

The unit may be provided with a conversion device operable to convert the walls between the transport position and the operating position and vice versa. The extension of the unit can be done in several ways: manually, pneumatically, locomotive or hydraulically. The conversion device may comprise manually operated cables, chains and the like, and optionally a pulley system therefor. In a compact embodiment, the cylinders are housed in the liner or bottom of the unit. In particular, the background is suitable for this purpose. The cylinders can, for example, drive cables that run through the bottom or cladding to the corner columns and transfer the lifting forces into the columns to extend the unit. In one embodiment, the unit can be converted from the transport position to the operating position by means of a forklift, the fork of which engages the upper section, in particular the lining.

It is an object of the invention to provide a residential space designed as a unit that can be transported efficiently.

It is an object of the invention to provide a residential space designed as a unit that is suitable for efficient group transportation.

It is an object of the invention to provide a residential space designed as a unit that is advantageous in terms of transport energy required.

According to a further aspect, the invention provides a transportable (residential) unit for forming a residential space in the form of a right parallelepiped, provided with a bottom and a lining, and side walls extending between them, which side walls can be converted, particularly telescopically extendable/retractable, between a transport position -particularly retracted-, in which the residential unit has half the standard height of a standard cargo container, and an operational position -particularly extended-, in which the unit has a higher height. Since in the lowered, specially retracted position, the residential unit is half the standard height, two such units, in the lowered, specially retracted position, placed one on top of the other, will correspond in height to a standard container fixed (ISO) standard height. In this way, two retracted residential units can be moved within the same transport volume. Two retracted residential units take up as much space as a normal shipping container. Due to the half height of the residential spaces during transport, the inventory can also remain at least substantially in the residential space and there is room for the transport of other goods that are required at the destination, such as walkways, barriers. The furniture and/or the pipes can be housed, at least substantially, in the section of the unit that comprises the bottom.

In the operating position, the unit preferably has a full standard height, so that in multiple transport with an odd number of units a standard height can always be provided if one unit is not retracted.

The unit can be equipped in various ways, depending on the intended use, such as sleeping unit, sanitary unit (short stay), kitchen.

According to the invention, the unit is equipped as a sanitary unit having a series of toilet bowls, urinals and/or showers.

According to another aspect, the invention provides a transportable unit for forming a residential space in the form of a right parallelepiped, provided with a bottom and a cladding, and walls extending between them, which walls can be converted between a transport position -particularly retracted - and an operative position -particularly in the extended vertical direction-, in which the walls each comprise an upper wall attached to the lining and a lower wall attached to the bottom, where the upper wall and the lower wall of at least one side wall comprise an upper door part and a lower door part, respectively, to form an entrance door to the residential space in the operative position, where the upper door part and the lower door part can rotate around a center vertical hinge line and are attached to the cladding and bottom by a top hinge and a bi lower hinge, respectively, wherein the hinge center lines of the upper hinge and the lower hinge are aligned with each other. The upper part of the door and the lower part of the door can, in that case, be provided with connecting pieces to be mutually connected in the operative position. In one embodiment, the upper part of the door and the lower part of the door can slide vertically into each other. In another embodiment, the upper part of the door and the lower part of the door can slide along each other in the vertical direction.

To prevent the unit from being moved from the transport position to the operating position during transport handling, the unit may be provided with means for locking the unit in the transport position.

The unit can be equipped in various ways, depending on the intended use, such as sleeping unit, sanitary unit (short stay), kitchen.

According to the invention, the unit is equipped as a sanitary unit having a series of toilet bowls, urinals and/or showers.

According to another aspect, the invention provides a set of two units according to the invention, stacked one on top of the other.

According to another aspect, the invention provides an assembly of a number of transportable units according to the invention, in which one unit has a length L corresponding to the standard length of a standard cargo container and n units have a length L' corresponding to 1/n x L, where n is an integer.

DETAILED DESCRIPTION OF THE DRAWINGS

The container-shaped sanitary unit 1 of Figures 1A and 1B comprises a lower section 1a and an upper section 1b. The lower section 1a comprises a bottom 2a, longitudinal sidewalls 3a, end sidewalls 4a, and usually longitudinal beams 6a, cross beams 7a, and columns 8a. The upper section 1b comprises a skin 2b, longitudinal side walls 3b, end side walls 4b, and usually longitudinal beams 6b, cross beams 7b and columns 8b, see also Figures 2A,B. Beams 6a,b and 7a,b and columns 8a,b meet at the corners, where standard (ISO) corner fittings 5 are located. Columns 8a,b are interlocked so that they are able to absorb vertical weight forces and also in case of lifting forces exerted on the corner fittings 5 in the cladding 2b do not move relative to each other to facilitate loading on a truck, train, ship, etc.

In Figure 1A the containerized unit 1 is shown in the retracted shipping position where it has a length L of 20 feet, a width B of 8 feet and a height H1 of 4 feet 9 inches. As a result, unit 1 has the length and width of a 20' TEU container, but half the standard height of 0.5 Hs of a standard container -in this case different-, in this case a High Cube container. (9 feet, 6 inches).

When two container-type units 1 are stacked for transportation in the condition of Figure 1A one on top of the other, then the joint height, see also Figures 2A and 2B, equals the standard height Hs of a High Cube container, is say 9 feet 6 inches. The 20-foot length is advantageous for transport by a truck adapted to transport TEU containers, with or without a trailer ditto, see also Figure 7.

In Figure 1B the unit 1 has been converted from the transport position to the operating position, in which the height is H2 which can be equal to 2 x H1 (=Hs). The upper section 1b extends upwards and in that position the columns 8a,b are locked together, whereby the longitudinal beams 6a,b, the cross beams 7a,b and the columns 8a,b form a frame. Longitudinal sidewalls 3a,b and end sidewalls 4a,b now form longitudinal sidewalls 3 and end sidewalls 4. They can be designed in various ways, a longitudinal sidewall 3 with doors 20 is shown (see also Figures 6A,B) and an end side wall 4 with sinks 37. A mirror wall behind the sinks slides down behind the sinks 37 when the unit is telescopically retracted.

This can be seen in Figures 2A,B. The mutual locking of the columns 8a,b takes place by means of a locking pin 40, which can be inserted and secured in a suitable hole of a vertical series of holes in the columns 8a,b, both in the transport position of Figures 2A ,B as in the operative position of Figures 2C,D. Selecting H1 to be half the standard height (0.5 Hs) of a High Cube container (L= 45ft, B= 8ft, H=9ft 6in) instead of half the standard height (0.5 x 8 ft 6 in) of a 20' TEU container, the overlap of columns 8a and 8b in the operating position may be longer. The greater overlap may be advantageous for the design of the connection (as well as its stability) between both columns 8a,b in the operative position.

In the stacked position of Figures 2A,B all the outside dimensions of the units 1, also the appendages, remain within the standard dimensions in question, in this case that means the 20 feet length, the 8 feet width and the 9 feet 6 inches tall.

In order to extend the unit 1 to the operative position, a central cylinder 10 is arranged in the bottom 2a, within the profile of the bottom 2a, in which a fixing plate 12 is arranged at the end of the piston rod 11. On it plate 12 the cables 13 are fixed (see also Figures 2E and 2F) circulating around the pulleys 14c,d at the bottom 2a up to the four corners, in which they are guided around the pulleys 14a in the vertical direction, until the pulleys 14b at the upper end of the columns 8a, see Figures 2B and 2D. The outer ends of the cables 13 are attached to the lower end of the columns 8b. In this way, almost the entire conversion device is housed in the lower section 1a.

By retracting the piston rod, from the position of Figure 2E to that of Figure 2F, the cables 13 and their outer ends are pulled upwards, while the lower end of the columns 8b is brought upwards, until reaching the position of Figure 2C,D. In the extended position, the extended part of the unit with the columns 8b largely remains in the non-extended columns 8a to form a stable unit. The blocking occurs where the columns overlap each other.

Locking of the extended position therefore takes place both in the fully retracted position and in the fully extended position. In the retracted position said lock offers the telescopically retracted unit a non-detachable character and provides a high degree of unit rigidity to meet the demands made by transporting the unit. In the extended position, the lock provides security and relieves lifting cables and cylinders. The blocking can be done automatically, mechanically, pneumatically, hydraulically or manually.

The side walls 3a,b, 4a,b and the columns 8a,b can slide in/out or along them, depending on the form of construction and the specifications of the extended unit and the technical demands that are made. pose him. The extension system can also be incorporated into one or several columns that can be located elsewhere in the unit than the corner columns. If the functionality of the unit does not allow the lifting system to be placed at the bottom, it can also be incorporated elsewhere to provide the same functionality.

In Figures 2A-D, the interior space of the unit is divided by the longitudinal partition wall 60 into two series of subspaces, namely, subspaces 30 for urinals 32 and subspaces 31 for toilet bowls 33, in which the adjacent subspaces they are separated from each other by inner walls 29a,b, wherein the inner wall part 29a forms part of the lower section 1a and the inner wall part 29b forms part of the upper section 1b. The wall parts 29a, 29b can slide along each other when retracting/extending the unit 1. On the longitudinal sides, both series of subspaces are accessible through individual doors 20 (Figures 1A,B). All pipes for slopes and for drainage (34,35) are housed in the lower section 1a. In the case of urinals, doors and the manufacture of subspaces can be dispensed with, instead partitions can be mounted on the central wall, which if necessary can also be divided into one part attached to the upper section and another to the lower section of the unit, during conversion to be telescopically extended to the desired height in the operating position.

The device can also be designed differently. For example, an example of a combination of subspaces 30 for urinals 32 and subspaces 31 for toilets 33 in combination with subspaces for showers 39 is given in Figures 3A-D. Figures 4A-D show an arrangement that has only subspaces 38 for showers 39. An assembly is shown in Figures 5A-D that only has subspaces 31 for toilet bowls 33.

Figures 2C and 3C illustrate that the partition wall 60, which forms a main partition between two series of toilet bowls and/or urinals, is divided into a two-part lower partition wall 61a and an upper partition wall 61b. For each toilet bowl or urinal, each bottom part of the partition wall 61a houses a drain/conduit 62 for discharging water/urine/faeces to a central drain pipe 63 arranged at the bottom, which drain pipe can be connected to a system. of emptiness. Both portions of the lower partition wall 61a define a receiving space 64 for the upper partition wall 61b in the transport position of the unit 1.

In the example of Figures 1A,B the doors 20 are constructed from a lower door part 20a, which forms part of the lower section 1a, and an upper door part 20b which forms part of the upper section 1b. The lower part of the door 20a is provided with a handle lock 21. The particularity is that each of the door parts 20a,b is not attached to a post by means of a hinge, but to the bottom 2a and to the cladding 2b by means of hinges 22a,b. Its hinge center lines S1 and S2 are aligned with each other, so that the extended door 20 can act as a hinge and function as a unit. The (entrance) doors 20 can be equipped with individual locks with which the door can be locked in both the extended and retracted position. The positions of the hinges along the vertical edges of the door parts 20a,b do not have to be taken into consideration. By means of locking pins 23, both door parts 20a,b are connected to each other so that they swing together during use. Hinges suitable for this purpose are known from shower walls and cooling space walls, eg see Prisma series hinges from CR Laurence of Europe GmbH. The door parts 20a,b can slide either inside or along each other. Optionally, the doors can also be designed in such a way that they fold.

In the embodiment shown in Figures 8C and 8D the series of subspaces 28' is formed by the boxes 28a' and 28b'. The vertical walls 29', of which those located at the ends of the unit can form side walls of the unit, are also divided into a lower part 29a' and an upper part 29b' that form part of the lower section 1a' and of the upper section 1b', respectively. Each of said boxes 28a', 28b' comprises three vertical walls, namely on both sides (29a', 29a' and 29b', 29b') of the subspace and facing the entrance, as rear wall (20a' and 20b). '), which are preferably formed as a unit with each other, such as polyester. Furthermore, it is preferred that the boxes have a bottom and a liner, respectively, formed integrally with the boxes. On the entrance side (not visible in the drawing, facing backwards) and on the opposite sides, both boxes are open. The upper box, which is part of the upper section of the unit, is therefore inverted with respect to the lower box, which is part of the lower section. When converting the unit from the shipping position of Figure 8C to the operating position of Figure 8D, the walls of the vertical box can slide closely together. A comparable configuration is also possible for larger units, such as unit 1, discussed above.

An assembly 100 of four units 1 can be transported by means of a trailer truck, see Figure 7, with units 1 according to the invention, in which two stacked units, each of which has a height H1, occupy altogether a height Hs that is equivalent to the standard height of a standard container, in this case 9 feet, 6 inches of a High Cube container.

It is also possible to transport a complete "sanitary village" with the truck combination of Figure 7. Such a village is shown in Figure 9, comprising three sanitary units 1 and five smaller units 1' which can be converted from a transport position to an operative position comparable to the units 1, see Figures 8A, 8B in which in the transport position they have a height corresponding to H1 of the units 1. In Figure 7 said smaller units 1' are indicated with striped lines. Like the units 1, units 1' are supplied with standard corner fittings 5 and have a length L' of 8 feet, equal to the width of unit 1 and a width B' of an integer fraction of the length L of unit 1 , in this case 1/5 of it, 4 feet. The units 1' can be furnished as shower rooms, toilet rooms and/or urinal rooms, particularly with the said boxes, and in the configuration shown they form a closure of the area 101 at the ends of the units 1. By means of the door 102 is provided with a closed and controllable sanitary area 101, accessible through a closable entrance 103.

Instead of doors, window panes can also be used both in the upper section 1b and in the lower section 1a. Entrance and inspection doors can be used in both the upper and lower sections. Entry doors using the fully extended height are constructed to be retractable so that proper operation in the extended position is ensured.

The frame of the unit can be made of steel or stainless material that is strong enough to ensure functionality in the retracted and extended position. New materials may be used in the future if strength, price, and weight offer a suitable balance for the purpose described herein.

If necessary, special cross connections can be used in the construction to reinforce the frame, so that this construction meets the specific requirements in terms of equipment and function of the unit.

The retractable vertical columns (intermediate) that are not part of the load-bearing structure can also be made of steel or stainless material. The part that the other part slides on will be designed with more strength and larger size than the part that slides.

The walls and doors can be made of various materials, depending on the furnishings of the unit. The part that slides can be made of a light, thin and resistant material.

Providing intermediate walls of insulated sandwich panels is one of the options to protect technical components against weather influences. Frost protection or air conditioning can be applied in the resulting subspace.

In the event that the unit is furnished as a shower, urinal and/or toilet unit, the floors can be mounted sloping inwards. Against a dividing wall or back wall, in the floor, drains can be mounted through which cleaning and/or rain water can be evacuated. This helps prevent water from leaving the unit at the front, in front of the doors, and affecting the condition of the floor, thus limiting the formation of mud in front of the entrance doors.

The unit can be provided, among other things, with a system of boilers, water storage tanks, wastewater tanks, generator sets, vacuum pumps, etc.

The connection of all toilets, urinals, showers, sinks and all other devices that produce sewage, can be done through a system of sewage pipes. This system passes wastewater to a vacuum pump that processes and discharges it. As a result, a high degree of hygiene is achieved and this sanitary system also reduces water usage to a high degree compared to a conventional toilet flushing system. However, fitting of standard sanitary fittings with drainage under the influence of gravity/pressure, or a combination thereof with a vacuum system is also possible.

Inside, the unit can be provided with lighting, particularly in the upper section 1b. If there is a battery or generator, it will preferably be housed in the lower section 1a. The connection with the devices can be made through flexible lines capable of following the conversion movement of the unit. In order to keep the overall weight of the unit as light as possible, consideration is given to luminaires and light fixtures constructed to be lightweight.

In the lower corners, the unit can be provided with one or more lifting systems to be able to place the unit horizontally or in any position.

The liner itself may substantially retain the shape, plate-like or flexible, such as cloth-like, if the liner itself is not to be loaded with additional external weight. During transportation, the lining fabric will be protected by longitudinal beams 6b and cross beams 7b.

The bottom and/or cladding can be provided with an extendable panel which can serve as a step for the door panels or as a sun shelter/screen. These slide-out panels may be provided with lighting and/or display panels for information or advertising.

The examples given refer to the application of the residential space as a sanitary facility.

The unit according to the invention can be transported by standard transport, by truck, train, barge, ship, its transport being particularly profitable, and it can be used all over the world. After transport, the unit folds up and is ready for use in a few minutes.
