Description

Irrigation, box, drainage box, or an attenuation box and a set of two of these boxes
The invention relates to an irrigation box, a drainage box, or an attenuation box for handling ground water, that can control or otherwise attenuate water which falls for instance as rain, particularly in "flash" storms or from flooding, including flooding caused by melting ice and/or snow.
EP 0 943 737 discloses an irrigation and/or drainage box which, in combination with another box or other boxes , form an irrigation and or drainage unit or system to be placed in the ground . Such a uni or system can then withstand loads from the surrounding earth and/or loads on the ground. However , such a unit or system is not very capable of withstanding side soil loads or other side fo ces . For certain circumstances, it is desirable that the strength in lateral direction is improved . Such a box may also be known and used as an attenuation bo .
From EP 1 416 099 grids are known for placement between two boxes which form together a unit or system, referred to as a ground water or attenuation system . The positioning of the grid where the open sides of two boxes meet enhances stability, particularly when the grids are connected with other structures which are integral parts of each box . Such systems can the provide an improved capability to withstand, side soil loads or other side forces , so that the strength i lateral direction is acceptable.
However, the necessity of such a grid causes a number of problems. For a start, it makes the unit or system more complex, so that assembling such a unit or system could lead, to fatal errors . It is possible that the placement of such a grid will be forgotten, something which is not so easily noticeable once the unit or sys em has been assembled . The uni or system will then not have the expected lateral strength . The placemen of the grid requires additional time for the assembling. This increases labour costs. Furthermore, the production of the grid raises the costs for the entire unit or system. Finally, materials management at a construction site is needed to ensure that there is a sufficient number of grids for appropriately assembling the unit or system. The use of such a system will thus increase overhead costs.
The invention aims to solve at least one of the above problems. This is achieved by providing an irrigation and/or drainage box in accordance with claim 1. Accordingly, the. invention provides an irrigation box, a drainage box, or an attenuation box, comprising as integral parts of the box:
a base having openings therein for passage of fluid into and/or out of the box;
at least one side wall extending substantially perpendicularly relative to the base , the at least one side wall having openings therein for passage of fluid into and/or out of the box;
an open side which lies opposite the base , the open side being designed such that two of these boxes can be placed with the open sides towards one another and then be connected to one another to adopt an assembled condition;
at least one column which extends from the base towards the open side substantially vertically when the base is in a horizontal position; and
at least one connecting part between
• one column which is positioned free from direct contact with one of the at least one side wall and one column which is positioned in direct contact with one of the at least one side wall, and/or between
• one column which is positioned free f om direct contact with one of the at least one side wall ana one of the at least one side wall, the connecting part being free from direct contact with the base .
By providing as an integral part of the box a connecting part between columns and/or a side wall, the capability of withstanding side soil loads or other side forces is improved, whilst also at least one of the prior art problems is solved. It is to be noted that in line with definitions widely used by well-established dictionaries, the word "integral" embraces "necessary to the completeness or integrity of the whole, not merely attached". A box comprising as integral parts of the box certain features is thus a single-piece box, not composed or assembled from a plurality of parts into a single piece, but produced "at once" as a single piece.
Although in one aspect the invention is directed to a single box, that single box has an open side which is constructed for placement of an identical open side of another box against the open side so that the single box is then in an a sembled condition . The open side can be seen as being defined by an end of the at least one wall. The open side can also be seen as having a contour which allows for matching a contour of the open side of another box having an identical open side .
In an embodiment of a box according to the inven ion, the box is such that in the assembled condition the columns of one of these boxes is one-to-one connected up with the columns of the other one of these two boxes. Within the. context of the present invention, this has the advantage that the additional strength in lateral direction can be "passed on" from one box to the other. Consequently, it is not necessary that each column in each box is stiffened up by the maximum number of connecting parts . It will be possible to reduce the number of connecting parts without a significant loss of lateral strength. Less connecting parts will obviously ease manufacturing , reduce the material needed for the production of such a box and overall minimize the costs.
In an embodiment of a box according to the invention, the at least one connecting part is positioned such that in the assembled condition none of the at least one connecting parts of one box has a mirror position with respect to the position of the connec ing parts of the other box, he mirror plane being the plane where the open sides meet. In suc an embodimen , there is per area, of interface between the boxes an optimized number of connecting parts. Such a box strikes a balance between costs and improvement of strength in lateral direction. Thus , in or close to the plane where the open s ides meet when the box is in an assembled condition, connecting parts of the different boxes are not in a mirrored position with respect to each o her .
In an embodiment of a bo according to the invention, the at least one connecting part is positioned such that in the assembled condition each of the at least one connecting part of one box has a point symmetrical position with respect to the position of the connecting parts of the other box, the point of symmetry being the centre point of the plane where the open sides meet . Thus, the at least one connecting part is positioned for obtaining a point symmetrical distribution of the at least connecting parts of two of these boxes when these are together put in the assembled condition . Advantageously, this embodiment can be such that only one type of box needs to be produced, keeping product:ion costs low, planning , material management , storage control , etc . easy and straightforward. Furthermore, the box can still be produced in such a way that also without placement in the assembled condition, the box has sufficient strength in all relevant directions , so that for instance , stacking of such boxes other than in an assembled condition, will not lead to deformation of such boxes under their own weight and will avoid undesirable phenomena such as creep and other forms of plastic deformation.
In an embodiment of a box according to the invention, the at least one connecting par is positioned such that in the assembled condition each of the at least one connecting part of one box is in a mirror position with respect to the position of the connecting parts of the other box, the mirror plane being the plane where the open sides meet. In this embodiment, the columns of the two boxes when connected up one-to-one, are supported in the lateral direction by double the amount of connecting parts, giving superior strength in lateral direction.
In an embodiment of a box according to the invention, a number of connecting parts is oriented perpendicular to the orientation of the remaining number of connecting parts. In such an embodiment, the strength in the lateral direction is improved not only in one lateral direction but in two lateral directions which are perpendicular to each other.
In an embodiment of a box according to the invention, at least one of the connecting parts is positioned between the base and the free ends of the at least one column. In such an embodiment , the position of the connecting parts can be optimized such that two connecting parts in mirror position (the open sides forming the mirror plane) can optimally contribute o the overall thickness of two columns which are one-to-one connected up with each other. The lateral strength and stiff ess of a single box may optimally be improved in that case .
The invention is further related to a set of two boxes wherein one of the at least one connecting parts of one bo is arranged to adopt a mating position with respect to one of the at least one connecting parts of the other box for reinforcing the respective parts. The invention also relates to a set of two boxes as described above, wherein the boxes are identical and are corinectable to one another through male and female connector parts.
The invention will further be explained on the basis of a drawing which shows in;

In the drawing, like references refer to like parts .
Fig . 1 shows an embodiment of an irrigation box, a drainage box, or an attenuation bo . The box is a one -part construction, i.e. all parts are integral parts of the box 1. The box has a base 4 with openings 4a therein for passage of fluid into and/or out of the box 1. The box has four side walls 5a, 5b, 5c, 5d, each extending substantially perpendicularly relative to the base. Each side wall is provided with openings 5e therein for passage of fluid into and./or out of the box. Two side walls 5a, 5b extend along the longitudinal direction and two side walls 5c, 5d extend along a transverse direction . As shown, box 1 is block- shaped . However, it is also conceivable that the block is cylindrical in shape and that the side wall concerns one wail which is closed in itself, i.e. endless. Of course, also other shapes are possible , such as formed by side walls which extend in vertical direction and form together a triangle, a pentagon, a hexagon, an octagon, etc . The box. can also be substantially L- shaped, or cross- shaped . In any case, the box 1 has an open side 6 which can be seen as defined by an end of the side walls and which is situated opposite the base 4. The open side 6 is designed such that two of these boxes 1 can be placed with the open sides 6 towards one another and then be connected to one another to adopt an assembled condition . Thus , a single box is considered to be in an assembled condition when an identical open side of another box is placed against the open side of that single box . For this purpose the open side has a contour whi h allows for fitting and matching to a contour of the open ide of another box having an identical open side. A single box having no open side of another box placed against its open side is in an unassembled condition.
Box 1 is provided with columns 7 which extend substantially vertically from the base 4 owards the open side 6. A number of columns 7 may be positioned ree from direct contact with any of the side walls 5a, 5b, 5c, 5d . Such free-standing columns are denoted by the reference 7a. Howeve , it is also possible that one or more columns are positioned i direct contact with one of the side walls 5a, 5b, 5c, 5d . Those columns are denoted with reference 7b. Box 1 comprises connecting parts 8 as further integral parts of box 1. Such a connecting part 8 may be between one column 7a which is positioned free from direc contact with one of the side walls 5a, 5b, 5c, 5d and one column 7b which is positioned in direct contact ith one of the side walls 5a, 5b, 5c, 5d. Such connecting parts are denoted by the reference 8a. However, additionally, or alternat iveiy, such connecting parts 8 may also be between one of the side walls 5a, 5b, 5c,
5d and one column 7a which is positioned free from direct contact with one of the side walls 5a , 5b, 5c, 5d. Such connecting parts are not shown in the drawing. However, the drawing shows embodiments wherein connecting parts 8b are. between two columns 7a which are each free from direct, contact with side walls 5a, 5b, 5c, 5d .
In general it applies that the connecting parts 8, 8a, 8b are free from direct contact with the base 4. As shown in Figs. 1-4 and Fig. 6, it is possible that the connecting parts 8, 8a, 8b each connect up with column 7, 7a, 7b at the free end 9 of the respec ive column 7, 7a, 7b. The free end 3 is considered to be the end of the column which is opposite the end that is connected up with base 4.
Fig . 5 shows an embodiment wherein the connecting parts 8, 8a, 8b are each positioned between the base 4 and the free end 9 of columns 7, 7a, 7b.
It is possible tha in the assembled condition the columns 7 , 7a, 7b of one of two boxes 1 are one-to-one connected up with the columns 7, 7a, 7b of the other one of two s c boxes 1. T is can easily be imagined for each of the embodiments shown .
Note that the free ends 9 of the columns 7, 7a, 7b of the box shown in Fig. 2 are provided with so-called male connector parts 10. This equally applies to the embodiment shown in Fi . . However, also note that the embodiments of a box 1 according to the invention as shown in Fig . 1 , 3 and 5, depict so-called female connector parts 11 at the free ends 9 of the columns 7a, 7b, 7c.
It will be understood that the bo shown in Fig . 2 can easily be put into an assembled condition by letting the open sides 6 of the box shown in Fig . 2 and in Fig. 3 meet and he male connectors 10 and female connectors 11 connect up. Note that in the embodiment shown in Fig, 2, the connecting parts 8, 8a are oriented parallel to the transverse side walls 5c, 5d . In contrast, in the embodiment of box 1 as shown in Fig. 3, the connecting parts 8, Sa, 8b are oriented parallel to the longitudinal side walls 5a, 5b. By assembling the box shown in Fig. 2 with the bo shown in Fig. 3, the columns 7, 7a, 7b in each of these boxes are optimally supported and the obtained assemblage of two ir iga ion boxes 1 has a relatively strong lateral strength (in this context understood to be a strength considered in a direction parallel to base 4 arid/or open side 6 ) .
It is possible to have both male connector parts 10 and female connector parts 11 in equal numbers distributed over the free ends 9 of the columns 7a, 7b, . Fig. 6 and Fig. 7 show an exam le of this . Note that the free ends 9 of the column 7d have partly a male connector part 10 and partly a female connector part 11. It is also possible that the box having the male connector parts 10 and female connector parts 11 distributed over the free ends 9 of the column 7a, 7b, can be such that two identical boxes 1. can be put together in an assembled condition. An embodiment of a box suitable. for that purpose is shown in Fig . 7. That box is connectable to an identical box by means of connecting the male and female connector parts 10 , II .
When two boxes as shown in Fig . 7 are available , then these can each be put in an assembled condi ion by rotating one of the boxes around a axis which has its axial direction parallel o a width of that box and then place the open sides against each other and connect the male connector parts 10 and the female connector parts 11. Thus , each single box is such that it is connectable to an identical box . A number of the connecting parts are oriented perpendicular to the orientation of the remai ing number of connecting parts . The columns having female connector parts are connected by connecting parts which extend in a direction perpendicular to the direction into which connecting parts connecting columns having male connection parts extend.
The box shown in Fig. 7 has at least one column which is connected by a number of connecting parts of which at least one connecting part extends in a direction that is perpendicular to the direction into which at least one other connecting part of that member extends. As shown, Fig. 7 has two such columns .
For such boxes 1, it is possible that connecting parts 8, 8a, 8b are positioned such that in the assembled condition each of these connecting parts 8, 8a, 8b of that box 1 are in a mirror position with respect to the position of the connecting parts 8 , 8a, 8b of the other, identical, box 1. The mirror plane is then the plane where the open sides 6 meet. Examples of such configurations of the connecting parts 8, 8a, 8b are shown in Fig. 1 and Fig. 5.
However, it is also possible that the connecting parts 8, 8a,
8b are positioned such that in the assembled condition none of the connecting parts 8, 8a, 8b of one box has a mirror positio with respect to the position of the connecting parts 8, 8a, 8b of the other, identical , box 1. Again, the mirror plane is also in this context the plane where the open sides 6 meet. An example of such an embodiment is shown in Fig. 6.
It is further also possible that the connecting parts 8, 8a, 8b are positioned such that in an assembled position each of these connecting parts 8, 8a, 8b of one box has a point- symmetrical position with respect to the position of the connecting parts 8, 8a, 8b of the other, identical, box. In this context the point of symmetry is the centre point of the plane where the open sides 6 meet. Although the drawing does not show such an embodiment, a skilled person will have no problem in visualizing such an embodiment. Fig. 4 shows an embodiment of a box 1 according to the invention wherein a number of the connecting parts 8, 8a, 8b are oriented perpendicular to the orientation of the remaining number of the connecting parts 8, 8a, 8b. The Figs. 1-5 show boxes wherein each of the connecting parts 8, 8a, 8b is oriented parallel to one of the side walls 5a, 5b, 5c, 5d . In contrast, Fig. 6 shows a embodiment of a box 1 according to the invention wherein the connecting parts 8 are oriented diagonally with respect to the side walls 5a, 5b, 5c, 5d.
Although the drawing only shows embodiments of boxes according to the invention wherein the connecting parts 8, 8a, 8b extend in a direction parallel to base 4 and/or open side 6, for another embodiment (not shown) it is not inconceivable that at least one of the connecting parts 8, 8a, 8b is oriented diagonally with respect to the base 4.
It is also not inconceivable that one of the connecting parts 8, 8a, 8b connects at least three columns 7, 7a, 7b, as shown in Fig . 6.
Fig. 8 shows a perspective view onto a bottom at the outside of a base. The connecting parts form a pattern that is also present in the base, as visible in the bottom at the outside of the base. Within the framework of the technical preferences and requirements many different designs are possible . This applies to each of the embodiments shown and discussed .
Although not shown in the drawing, the disclosure is also related to a set of two boxes according to the invention as explained with reference to various embodiments, wherein the connecting parts 8, 8a, 8b of one box 1 are arranged to adopt in the assembled condition a mating position with respect to one of the connecting parts 8, 8a, 8b of the other box, for reinforcing the. respective connecting parts . Thus one box may have connecting parts having a U- shape in cross-section, and the other box may have connecting parts which fit in the U- shaped connecting parts of the other box, This would enhance the stability and stiffness of the two boxes in their assembled condition.
It will be clear that other configurations for the connecting parts are possible. Besides the U-shape in cross section other shapes are possible e.g. + , j, o, J , □, H, or a segment of a circle. As shown in Fig. 7, it is also possible that connecting parts between columns having female connectors are each provided with ridges . The same applies to connecting parts between columns having male connectors. Connecting parts between columns having both a male and a female connector part can be flat at the side which will in the assembled condition be in touch with the same connecting parts of another box.
The boxes as described above can be made of plastic , for instance by molding techniques.
The invention is not limited to the embodiments described above . Many variations and modifications are possible. For instance , a box according to the invention may comprise more than one connecting part between a pair of two columns and/or between a certain column and a certain part of a side wall. Although the connecting parts are in the drawing shown to be. straight, it is not inconceivable that some curvature is included. The columns may be round columns, square columns, pentagons, hexagons, octagons, etc. The term "column" also embraces a part of a side wall which is locally thicker to provide the function of a column . Such a thicker part of the side wall may equally extend subs an ia11y vertically from the base toward the open side . The openings may have various shapes. In principle there is no limitation to the shape of the openings. Although it has been shown that the connector parts may be of the type male and. female , both integral parts o the respective boxes, it should be understood that the invention is not limited to boxes having connec or parts as integral parts of the box. It is equally possible that the connector parts are separate parts.
The side walls are not necessarily panels which extend in vertical direction. The side walls may equally be composed of bars which have, for instance , a circular or a rectangular cross section and extend in horizontal direction.
Many variations and modifications are possible within the framework of the invention, as defined by the appending claims .
