Background

Tradespeople typically carry out their trade on-site. Thus, they often need a method of transporting materials and tools required for carrying out their work. A vehicle used by tradespeople may be a medium sized van which offers modest storage capabilities. Furthermore, another consequence of needing to work on-site is requiring a portable workspace(s)/worksurface(s). This equipment fills up the already limited space of the medium van capacity yet further. Simply increasing the size of the van is undesirable since larger vehicles may be less fuel efficient, harder to drive down all types of roads and to park, more expensive to rent, and harder to source. Custom van cavity dividers can be cumbersome to have installed, need changing when the van is changed, significantly increase a load on the vehicle, and damage the vehicle interior, to name a few non-limiting drawbacks.

The invention described herein aims to provide a utility unit which is suitable for installation in all types of average tradesperson vans, which mitigate some of the above-described problems.

The invention comprises a utility unit having three main elements: a load bearing base unit, at least one module, and optionally one or more accessories. The base unit size is determined by the size of a cavity of the vehicle.

The base unit forms a base structure of the utility unit system and is the core of the utility unit system to be expanded upon through addition of modules and accessories. The base unit secures to an internal vehicle cavity via the vehicle cavity’s original lashing points. These original lashing points may be on the vehicle cavity floor or the vehicle cavity wall. The base unit of the invention may be configured to secure to the floor only, the wall only or both the wall and the floor. The utility unit may comprise attachment means (fixing means) for attaching the base unit to the lashing points. The attachment means provided may be dependent on the particular lashing points to be used (i.e. , the walls, the floor or both the walls and the floor).

The base unit has a first upper side, a second lower side and two further sides substantially perpendicular to, and connecting together, the first upper side to the second lower side. Thus, the base unit horizontally divides the vehicle cavity, providing both a raised platform and a tunnel-like compartment (loading compartment). Since the tunnel-like compartment is open ended, it is not limited longitudinally. However, it is limited laterally by the substantially perpendicular side walls. The side walls stiffen the platform in the direction of travel (of the vehicle in transit) and facilitate loading of equipment and/or materials into the loading compartment whilst protecting the vehicle cavity’s interior.

The base unit is comprised of a main frame with supporting panels attached thereto. The main frame may be comprised of a plurality of rectangular subframes configured to be orientated perpendicular to the direction of travel (of the vehicle when in transit). The subframes are connected together by side panels and optionally by stiffening brackets. In this arrangement, the number of subframes can be increased or decreased, or the length of the connecting side panels increased or decreased, to produce a required length of the main frame. The height of the side panels can be increased or decreased to produce the required height of the main frame. In another embodiment, the main frame may be comprised of subframe modules. The number and size of the subframe modules can be modified to produce a main frame of required dimensions. In some examples, the subframe modules are not identical to each other and the selection of the combination of subframe modules is selected according to the desired dimensions of the main frame/base unit.

The first upper side, and the second lower side, are comprised of a plurality of first upper, and second lower, panels respectively. Each of the plurality of first upper panels may be identical to each other. Further, each of the second lower panels may be identical to each other. Yet further the first upper panels may be identical to the second lower panels. The panels may be secured to a main frame through screwed connections. The screwed connections are distributed according to a repeating pattern.

Modules are then connected atop the first upper side of the base unit. A first lower side of the modules has a complementary part of a connection means distributed according to the aforementioned repeating pattern in the first upper panels of the base unit. For example, the first lower side has a series of holes and/or screws distributed according to the aforementioned repeating pattern and compatible with the series of holes or screws of the base unit. Modules are connected via direct connection to the main frame of the base unit or modules are connected via attachment to the panels. The modules may be supplied with two screw sets: one for mounting the module directly to the main frame and one for mounting the module on the panel(s). In both cases, the screws used to attach the panels to the main frame are replaced with suitable screws for mounting the module. Wherein the modules are to be connected directly onto the main frame, the first upper panel is removed (i.e. , for replacement by the first lower side of the module). This arrangement is advantageous since the utility unit is overall lighter from removal of some of the panel elements. In this arrangement, it is preferable that the area of the first lower side of the module is the same as an area of the panel. Alternatively, wherein the area of the first lower side of the module is smaller than the panel area, supplementary (filler) panels can be attached next to the module to account for the remaining exposed area. Thus, the modules either replace the first upper panels and attach directly to the main frame, or the modules are mounted to the first upper panels. In order to ensure compatibility with connection of the modules to the base unit, the modules must be scaled according to the aforementioned repeating pattern. Since the module’s hole/screw distribution for attachment is identical to that present in the panels, modules can be placed both parallel to, and perpendicular to, the direction of travel of the vehicle (when in transit).

The modules comprise a storage module (drawer) and/or a worktop module having a worktop surface part and a drawer compartment part.

Preferably, an internal width of the loading compartment enables loading and storage of standard plate material in accordance with Norwegian standard NS-EN 324-1 .

The base unit may be provided for installation partially assembled, for example, in the separate parts of: the subframes, the side panels, the stiffening brackets and the first upper panels and the second lower panels. The base unit can then be fully assembled inside the vehicle cavity.

The modules may be provided for installation in a fully assembled state. In some examples, the modules are provided for installation with an upper side of the module detached to allow easy access for attaching the module to the base unit or a below module.

The arrangement of the utility unit, having a base unit core, additional semi- customizable modules and further additional customizable accessories, allows the invention to be suitable for, and adaptable to, a range of industry sectors.

The utility unit is scalable and adaptable to the specific user needs of the respective industry sector by: adding subframes, lengthening/shortening side panels and adding/removing/rearranging modules and accessories. Thus, the present invention provides a standardized, simple-to-install system which is also adaptable and customizable to the specific user needs and industry sector.

Furthermore, as a result of the building block nature of the utility unit of the invention (i.e. , having a core base unit for which further modules are easily detachably attached onto), additional industry sectors can be studied, there particular needs identified, and additional specialised modules adapted to address these needs. These future specialised modules will be fabricated with the same cooperating connection means such that these additional modules are integratable with the utility unit of the invention.

Furthermore, the base unit and/or the modules have attachment points for accessories for further customization of the utility unit to the specific user’s needs. Accessories can, for example, be tool boards for mounting on the side of modules or the main frame of the base unit, trays and other organization solutions for drawers and/or various holders for tools and equipment to name a few non-limiting examples.

Particular arrangements of the utility unit of the invention will now be described with reference to the accompanying drawings. These particular arrangements are by way of example only and are non-limiting. Any features, or combination of features in any of the examples is combinable with any other feature presented throughout the description herein except where such features are clearly mutually exclusive.

Figures 1 , 2, and 4 to 13 show a particular example utility unit 1000 for installation into a vehicle, in particular a van, more particularly a type of van used by a tradesperson, yet more particularly a type of van used by a carpenter.

With particular reference to figures 1 and 2, the utility unit 1000 has a base unit 200 and an upper part 400. The utility unit 1000 has a first end E1 and a second end E2. When the utility unit 1000 is installed in a vehicle, the first end E1 is proximate to a rear opening of said vehicle and the second end E2 is proximate to a side opening of said vehicle. The upper part 400 is made up of a plurality of modules 410, 420, and optionally a plurality of accessories 510, 520, 530, for aiding different aspects of a tradesperson’s daily work. Figures 1 and 2 show the utility unit 1000 in a stowed position. In this position, the rear and side openings of the vehicle can be closed and the unit completely contained within the vehicle cavity.

With particular reference to figures 3a and 3b, there is a first subframe 202a, a second subframe 202b and a third subframe 202c. The subframes may be made of metal tubing, such as aluminium or steel tubing. Alternatively, the subframes may be made of flat sheet metal which provides easy incorporation of attachment points for panels during manufacture. In a yet further example, the subframes are made from plastic. The subframes are connected together by side panels 204, 206 and upper and lower stiffening brackets (not shown) to provide a main frame 202. The main frame 202 supports upper panels 205 and lower panels 203 to provide the base unit 200. The main frame 202 is constructed in a cuboidal arrangement. The base unit 200 is lightweight yet structurally strong in order to minimise load on the vehicle yet adequately support the upper part 400 of the utility unit, in particular, supporting the modules of the upper part in use such as when they contain contents for use. The unit ensures that the contents are stored safely and in accordance with applicable regulations.

The lower panels 203 provide a base surface to the utility unit 1000. The lower panels 203 are raised off the vehicle floor by a height HLP of around 50mm to 100mm, preferably 60mm to accommodate the lower stiffening brackets of the main frame 202. When the utility unit is installed within a vehicle, the lower panels 203 protect a floor of the vehicle cavity. The second upper panels 205 provide a load-bearing platform for supporting the upper part 400 of the utility unit 1000.

The base unit 200 provides a compartment (loading compartment/tunnel-like compartment) 250 for safe storage of objects, particularly large, heavy objects, such as objects that may be required in the daily work of a carpenter. For example, these objects to be stored in the compartment 250 may be doors, wood panels, window panes etc. The height HF of the main frame 202 is such that the compartment 250 can easily accommodate large objects that may be required in the daily work of a carpenter. The height HF of the frame 202 is between 10cm and 50cm, preferably between 20cm and 40cm, more preferably the height of the HF of the main frame 202 is 30cm.

The first lower panel 203 has an overhang 214a which protrudes beyond the main frame 202. The overhang 214a may bridge a gap between the lower panel 203 and a vehicle opening edge, when the unit 1000 is installed within a vehicle, to aid insertion of objects into the compartment 250.

The side panels 204, 206 protect the sides of the interior of the vehicle, for example from damage caused by movement of stowed objects in the compartment 250. Side panels 204 are positioned at the first end E1 between subframes 202a and 202b. One of the side panels 204 proximate to overhang 214a has a protruding portion 214b. This creates a right angle with the overhang 214a and further aids insertion of objects in the compartment 250 since a user can align the object against the right angle and slide the object against and forward to guide the object into the compartment 250. Side panels 206 are positioned at the second end E2 of the utility unit 1000, between subframes 202b and 202c. Side panels 206 have an aperture 256 to provide access to the stowed objects in the compartment proximate to the second end E2. This can facilitate insertion and removal of objects from the compartment 250.

The panels 203, 204, 205, 206 may be made from plywood, plastic or another suitably lightweight yet protective material. This allows adequate protection of the interior of the vehicle, adequate load bearing properties for upper elements of the utility unit, whilst being lightweight so as to minimise load on the vehicle by the utility unit. Upper panels 205 have a series of apertures 226 distributed in a regular formation.

These apertures form part of a connection means between the base unit 200 and a plurality of modules to be attached.

Three subframes 202a, 202b, 202c are shown in the example of the figures. However, the number of subframes can be decreased (to at least two) or increased (to, for example, four or five) to decrease or increase the length of the base unit 200 to suit vehicles of different lengths. For example, for short vehicles, the base unit 200 may consist of the first subframe 202a and the second subframe 202b joined by corresponding side, upper and lower panels. In another example, for longer vehicles, the base unit 200 may comprise an additional fourth subframe and be connected to the third subframe 202c by further panels. In another example, the base unit is made up of subframe modules wherein a subframe module is constructed of two subframes connected by side panels. The base unit is then constructed from one or more subframe modules connected in series. A length of the base unit can be chosen based on the number of subframe modules in the series.

Furthermore, the panels 204, 206, 203, 205 are shown in the example of the figures to have the same length. However, the length of the panels can be varied to accommodate different vehicle lengths. For example, the panels between the second subframe 202b and the third subframe 202c may be longer than the panels between the first subframe 202a and the second subframe 202b such that the second end E2 of the base unit is longer.

The base unit 200 is the core of the utility unit for which all other features of the utility unit are (directly or indirectly) attached, and which facilitates, at least, the majority of connection between the utility unit 1000 and the vehicle. Preferably, a connection between the utility unit and the vehicle is entirely via the base unit. The base unit 200 is manufactured and design, as described above, to provide a rigidity to the entire utility unit 1000. With further reference to figures 1 and 2, positioned on top of the upper panels 205 is the upper part 400 of the utility unit 1000.

A particular example of the connection means between the base unit and the plurality of modules is described herein. However, other means of connection are applicable provided they are not mutually exclusive to the other features of the invention described. A bottom surface (first side) of each of the modules 410, 420 has a series of apertures (not shown) distributed in a regular formation. Said regular formation is complementary to the regular formation of the series of apertures 226 in the upper panels 205. One half of a locking peg is inserted into each of the series of apertures on the modules 410, 420 and the other half of the locking peg is inserted into each of the series of apertures 226 on the upper panels 205. The series of apertures have a centre-to-centre distance of approximately 5cm to 15cm, preferably 6cm to 12cm, more preferably 10cm. Thus, the modules are securable across the upper panels 205 in aperture centre to centre increments (i.e. in 10cm increments). The modules have a top surface 414, 424. The top surface 414, 424 of each of the modules also has a series of apertures 416, 426 distributed in a regular formation wherein said regular formation is the same regular formation of the series of apertures 226 of the upper panels 205. Thus, the series of apertures on the bottom surface of each of the plurality of modules is also complementary to the series of apertures 416, 426 on the top surface 414, 424 of the modules. In this way, the modules can be securely stacked on top of each other via locking pegs. The locking pegs have a length of 5mm to 20 mm, preferably 10mm to 15mm, more preferably 12mm. The apertures have a height of 5mm to 20mm, preferably 10mm to 15mm, more preferably 12mm. An external surface of each of the locking pegs is substantially contiguous with an internal surface of the respective aperture. Thus, each of the locking pegs fit snuggly into its respective aperture. In another example connection means, modules are connected to the base unit via threaded inserts through corresponding apertures in the base unit and the modules, in place of the locking pegs. In general, the locking peg-aperture connection means enables connection of modules of various lengths and widths of aperture centre-to-centre increments. Module width and/or length is delimited by the base unit and the connection means. For example, the module width may be a minimum of the centre-to-centre aperture distance (i.e.,10cm) and a maximum of the base unit width (i.e.120cm) and still be adequately secured to the base unit. Furthermore, the connection means enables connection of modules of various lengths and widths at various orientations and positions atop the base unit. Preferably, the width and/or length of the module is smaller than the width and/or length of the base unit 200 such that the modules do not overhang the base unit.

With reference to figure 4, an example attachment means 300 suitable for attaching the utility unit 1000 to a vehicle is shown. The attachment means 300 is in the form of a plurality of oblong plates 300a-300f having an oblong aperture 310a-310f, respectively. The plurality of oblong plates 300a-300f may be rotatably connected to the main frame 202. In particular, the oblong plates may be rotatably connected to a first lower end of each of the vertical posts of the subframe 202a-c, wherein the first lower end of the vertical posts of the subframes 202a-c are adjacent to a floor of the vehicle when the utility unit 1000 is installed within a vehicle. Each of the rotatable oblong plates 300a-300f may rotate over an area equal to the area of a predetermined circle (nr ² ) delimited by the main frame 202 of the utility unit itself. The predetermined circle is determined by its radius (r) equal to the length of the oblong plates. This feature facilitates bolting of the utility unit into pre-existing holes in the vehicle floor. The area covered by rotation of the oblong plates is relatively large such that the pre-existing holes are likely to fall within these areas. Preferably, the oblong apertures 310 in the oblong plates 300 extend substantially the length of the oblong plates 300 in order to maximise the potential of the apertures aligning with pre-existing holes. The length r of the oblong plates 300a-300f is between 5cm and 20cm, preferably 10cm to 15cm, more preferably 12cm.

Dotted lines 330 mark an area that respective plates 300 can traverse over.

Dotted-lined circle 350 marks an example of where a pre-existing or preformed hole in the vehicle floor may lie. This pre-existing hole 350 lies within the area 330a that can be traversed by the plate 300a. In order to tie the utility unit into this pre-existing vehicle hole, the plate 310a may be rotated in the direction of the arrow 360 until the hole 350 aligns with part of the aperture 310a. A bolt can be screwed down through the aperture 310a and the hole 350 to secure the plate, and thus the utility unit 1000, to the vehicle floor. This arrangement has the benefit of using existing connection holes (lashing points) in the vehicle. Thus, no new connection hole need necessarily be added or drilled, saving time and protecting the vehicle interior. Another pre-existing hole 340 is shown aligned with aperture 31 Of within plate 300f. Preferably, the attachment means comprises six plates 300a-f, two at each side of the subframes 202a-c, as shown. This arrangement provides a secure connection between the entire structure of the utility unit 1000 to the vehicle. The plates 300a-300f in the example of the figures are flat to avoid the plates obstructing an area in which they connect to the vehicle floor.

The upper part 400 of the utility unit includes a plurality of modules of different types.

With reference to figure 5, a first type of module is a worktop module 410. The worktop module 410 has a worktop surface part 415 and a worktop module base 412. The worktop module base 412 has base side portions fixed to, and extending substantially perpendicular from, the first upper panel 205. The worktop surface part 415 comprises the top surface 414 and worktop side portions 413 extending perpendicular from the top surface 414 along a length of the top surface 414. The worktop surface part 415 is substantially horizontally slidable with respect to the worktop module base 412 via a sliding connection means such as drawer sliders. Thus, the worktop surface part 415 can extend outwards from the utility unit 1000. The worktop module 410 has side portions, for example to accommodate the sliding connection means. Thus, there is a space underneath the worktop surface part 415. The space is utilised by nesting a drawer compartment 418 inside said space. The drawer compartment 418 is also horizontally slidable with respect to the worktop surface part 415, for example via a second set of drawer sliders. The worktop module 410 is a multipurpose module and can be used as a workbench, for example, for supporting materials when working with them. For example, the worktop module can be used in sawing, drilling and sanding wood. The worktop module 410 can also be used to store items, for example small items that are used when using the worktop module as a workbench, such as nuts, bolts, screws, glues, varnish, polish, etc, and even larger items such as a circular saw or a table saw. This facilitates accessibility of needed items when most useful.

With particular reference to figure 6, a second type of module is a storage module 420. The storage module 420 has a storage module base 422 and a drawer 425. The storage module base 422 has base side portions 427 and a top surface 424. The base side portions 427 are fixed to, and extend substantially perpendicular from, the first, upper panel 205. The drawer has a drawer base surface 429, and drawer side portions 423 extending substantially perpendicularly up from the drawer base surface 429 along the length of the base 429. The drawer 425 is substantially horizontally slidable with respect to the base 422 via sliding connection means such as drawer sliders. Thus, the drawer 425 can extend outward from the utility unit 1000. The base side portions 422 and drawer base surface 429 have recesses 417 along their length for structural strength. The storage module 420 may have a shape, size and arrangement for storing larger items than draw 418. For example, the storage module may store tools for carpentry such as drills, saws, sanders etc. The interior of the draw 425 may be in the form of a built in tool box with recesses in the shape of particular tools. This allows a missing tool to be instantly identified to prevent leaving tools on site or at home. This feature also protects the tools and encourages good weight distribution around the storage module. Optionally, the storage module may have power ports in power connection with each of the recesses for tools that are powered. Thus, the tools can be charged when stowed in the storage module. The module 420 may further comprise a step-like angled insert such that the labels of storage boxes placed atop each step are readable from a natural viewing angle. Different inserts may be accommodated by the storage module 420 for different uses.

The arrangement of the upper part 400 in example utility unit 1000 of the figures shows a first storage module 420a arranged lengthways on, and at a front end E1 of, the base unit, a second storage module 420b arranged perpendicular to the length of, and at a rear end E2 of, the base unit 200, and a first worktop module 410a arranged lengthways on, and at a front end E1 of, the base unit 200 adjacent to the first storage module 420a. The first storage module 420a, the second storage module 420b and the first worktop module 410a make up a first level of the upper part 400. The upper part arrangement in the example in the figures further shows a second worktop module 420b stacked lengthways to the base unit 200 atop the first storage module 420a. The second worktop module 410b makes up a second level of the upper part 400. Other arrangement may be possible depending on a need of the user. However, preferably there is at least one storage module, at least one worktop module. More preferably the at least one storage module is arranged in a perpendicular arrangement to the arrangement of the at least one worktop module.

Further accessories are mountable to the utility unit 1000 and may depend on the need of the user.

With particular reference to figure 7, one of the additional accessories includes a storage cage 510 which can be used to secure larger items which are too large to be stored in the modules and/or tools that require quick access such as first aid kits, straps for securing items inside and on top of the vehicle or on a trailer, and extension cords etc.

With particular reference to figure 7 and figure 8, another additional accessory is a storage wall 520. The storage wall 520 has a wall frame 522 attachable to the main frame 202 of the base unit 200. The wall frame 522 may be attachable via rotatable oblong members 524. The oblong members 524 may swivel at the point of connection with the wall frame 522, and at the point of connection with the main frame 202 such that the distance between the storage wall 520 and an interior side wall of the vehicle is modified such that the storage wall 520 is substantially flush with the side wall of the vehicle. The connection design of the storage wall 520 allows the utility unit 1000 to extend outward to meet the internal side wall of the vehicle that the utility unit 1000 is installed within. A main part 526 of the storage wall 520 may be a fabric stretched across the frame 522 or attached plywood, containing various pockets and pouches 528 for storing items.

Figure 7 further shows some of the dimensions of the utility unit 1000. A width Wu of the utility unit is between 120cm to 200cm, preferably between 140cm to 180cm, more preferably 150cm. A height Hu of the utility unit 1000 is between 40cm to 200cm, preferably between 50cm to 180cm depending on a particular configuration of modules and accessories. These dimensions allow for the utility unit to be installed within the majority of commonly sized vans, in particular those used for carpentry.

With particular reference to figure 9, another additional accessory is a worktable module 530. The worktable module 530 has worktable frame 532, attachable to base unit 202, and a worktable panel 534. The worktable module 534 can be readily detached from the utility unit 1000 and placed on a stand, such as a sawhorse.

Figure 9 further shows length L of the utility unit 1000. The length L is between 150cm and 300cm, preferably between 200cm and 300cm, more preferably 220cm. The length may be determined by the number of subframes in the main frame 202 as explained above. This length renders the utility unit 1000 suitable for the majority of commonly sized vans, in particular those used in carpentry.

The plurality of modules 410, 420 are of a shape and size to substantially tesselate with each other on top of the base unit to maximise useable space. For example, a length of each of the plurality of modules 410, 420, 430 is substantially equal to the width of the base unit 200 such that when one of said plurality of modules is stacked atop the upper panel 205, perpendicular to the length of the base unit 200, a first end of the module is flush with a first side of the base unit and a second end of the module is flush with a second side of the base unit. Furthermore, a width of each of the plurality of modules 410, 420 is substantially equal to half the width of the base unit 200 such that two modules are stackable atop the upper surface 205 such that they abut along their length and are flush with either side of the base unit 200. In this way, storage space usage is maximised whilst minimising materials used and retaining ergonomic accessibility to areas of the utility unit 1000.

Each of the elements of the utility unit 1000 which are configured to extend outward have a handle 610, 620 for the user to grip. The handles 610 are a simple, L-shape. The handles 620 are a simple fl-shape. The handles 610, 620 are made of a lightweight material, such as aluminium, to minimise weight added to the utility unit and to reduce the risk of catching or snagging materials to be stored or transported in the utility unit 1000.

A width of the modules 410, 420 plus the length of the modules may be less than the length of the base unit 200 such that there may be a gap between a front positioned group of modules and a rear positioned module. The gap can provide a useful cavity for storage of large items such as tool bags, a vacuum cleaner and compressors to name a few non-limiting examples.

Figures 10 to 13 show the utility unit 1000 in an extended position.

With particular reference to figure 10, it is shown that an extension ESM2 of the storage module 420b is in a direction perpendicular to a direction of extension of the first worktop module 410a, the second worktop module 410b, and the first storage module 420a. This provides a utility unit 1000 that, when installed in a typical van, can utilise both openings into the van cavity, in particular the side opening door and the rear opening doors.

In another example configuration, wherein a vehicle in which the utility unit 1000 is installed has two side openings, a module configuration at the second end E2 comprising two modules (for example two worktop modules 410, two storage modules 420, or a worktop module 410 and a storage module 420) are arranged to extend out of respective first (i.e., left) and second (i.e. , right) side openings of the vehicle. In this configuration, the modules may have a length that is each half the width of the base unit and be placed back-to-back. Wherein a module is to be extended out of a side opening of the vehicle, the module width WM is smaller than a width of said side opening of a majority of commonly sized vans, in particular those used by carpenters. Since the second storage module 420b is positioned at the second end E2 of the utility unit and extends perpendicular to the other modules in the unit at the first end E1 , a torque derived from the extension and weight of the second storage module 420b is counterbalanced to a degree by the torque derived from the extension and weight of the other storage modules. This gives the unit an improved stability, in particular reducing strain of the attachment means 300 with the vehicle floor. A yet further benefit of the arrangement of the utility unit 1000 is that it encourages weight distribution of stored items throughout the volume of the vehicle cavity. For example, large, heavy items must be stored in the lower compartment 250, tools are distributed between the storage modules 420a and 420b, yet further tools can be stored in the storage wall 520. Furthermore, the unit ensures secure storage of items/tools. Since the items/tools are securely stowed in suitable modules, they are prevented from moving/sliding during transporting, thus protecting the items/tools from damage.

A further advantage of the utility unit 1000 is that it has the effect of segmenting the vehicle cavity space. This segmentation in combination with dual extendable modules significantly increases usable space for a particular van/vehicle cavity.

Figure 11 shows a right-side view of the utility unit 1000 with rear extending modules 420a, 410b in an extended position. The first storage module 420a may be substantially identical to the second storage module 420b, thus an extension ESMI of the first storage module 420a may be substantially equal to the extension ESM2 of the second storage module 420b.

In the example of figures 1-13, there are two worktop modules 410a, 410b, one at the first level of modules and one at the second level of modules. This configuration provides two workbench heights to the user. Different heights may be useful to account for different heights of prospective users and for accommodating different activities carried out on the workbench. For example, a greater height from the ground of the workbench may be desired for drawings/making measurements/etc than for sawing/sanding/etc.

Figure 12 shows the extension ESM of the storage module from a front-on view. The draw 425 can extend fully from the storage module base 422, thus doubling a total width of the utility unit 1000. The extension ESM may be between 100cm and 120cm. Figure 13 shows a left-side view of the extended utility unit 1000 with the worktop module having an extension E .

The utility unit 1000 is part-constructed outside of the vehicle and delivered to the user for installation within the vehicle in parts.

In the embodiment of figures 1 to 21 , the base unit 200 is transported in separate parts of: subframes 202a-c, stiffening brackets, side panels 204, 206, upper panels 205, lower panels 203 and attachment means, and is assembled within a cavity of a vehicle. This facilitates transportation of the utility unit parts as well as ensuring the utility unit is in parts which are light enough to be carried into the vehicle cavity.

With particular reference to figure 14 of an assembly flowchart, assembly of the base unit is achieved by, first, finding the lashing points and removing their latch cups/rings, 701. The oblong plates, or alternative attachment means, are placed over, or otherwise connected to, each of the lashing points, 702. Each of the subframes 202a, 202b, 202c are aligned with respective lashing points over respective attachment means (oblong plates in one example), 703. The subframes 202a, 202b, 202c are connected together by respective side panels 204, 206 and stiffening brackets to provide the main frame (skeleton), 704. Lower panels 203 are then secured to the main frame, 705. Upper panels 205 are next secured to the main frame, 706. Upon securing (bolting) the attachment means (oblong plates 300 in one example) through the lashing points, 707, the base unit 200 is constructed and secured to the vehicle floor. Once the base unit is secured in the vehicle cavity, the rest of the utility unit can be built up on top by attaching pre-assembled modules and accessories. The modules are stacked, 708, and accessories are easily secured, 709, to the base unit or each other to provide a personalised, yet easily assembled utility unit based on the user’s requirements and preferences. Furthermore, modules can be easily moved and changed based on a user’s changing requirements/preferences without needing to modify or damage a vehicle interior. A user is able to trial a particular configuration of elements of the utility unit without permanency or damage. Furthermore, a user can begin with essential elements of the utility unit and expand/extend based on need and budget.

Example assembly

Figure 15 explains an assembly method for a particular assembly example, and figures 16 to 21 show the utility unit at various stages of assembly of said particular assembly example. Many other assemblies and orientations are possible.

Once construction 801 of the base unit inside the vehicle has been achieved, at 802, a side edge of a first storage module is aligned with a side edge of the base unit, and a front edge of the first storage module is aligned with a front edge of the base unit. At 803, a plurality of locking pegs are slotted into the plurality of apertures on the lower surface of the first module and said locking pegs are slotted into complementary apertures on the upper surface of the base unit. Completion of step 803 give rise to the partially assembled utility unit of figures 16a and 16b wherein the first storage module 420a is connected to the upper surface 205 of the base unit 200.

At 804, a side edge of a second storage module of the second type is aligned with a rear edge of the base unit, and a front and rear edge of the second storage module is aligned with side edges of the base unit. At 805, a plurality of locking pegs are slotted into a plurality of apertures on the lower surface of the second module and said locking pegs are slotted into complementary apertures on the upper surface of the base unit. Completion of step 805 give rise to the partially assembled utility unit of figures 17a, 17b and 16c wherein the first storage module 420a and the second storage module 420b are connected to the upper surface 205 of the base unit 200.

At 806, side edges of a first worktop module of a first type are aligned with a side edges of the base unit and a side edge of the second module, and a front edge of the first unit are aligned with a front edge of the base unit. At 807, a plurality of locking pegs are slotted into a plurality of apertures on the lower surface of the first worktop module and said locking pegs are slotted into complementary apertures on the upper surface of the base unit. Completion of step 807 gives rise to the partially assembled utility unit, wherein a first level of modules is stacked, of figures 18a, 18b and 18c wherein the first storage module 420a, second storage module 420b and first worktop module 410a are connected to the upper surface 205 of the base unit 200.

At 808, a second level of at least one module is stacked atop the first level of modules, in particular, a second worktop module is stacked atop the first storage module. Step 808 is represented by figures 19a, 19b and 19c wherein second worktop module 210b is connected atop the first storage module 420a.

Accessories are then attached to the utility unit. At 809, a storage wall is connected to the main frame and, at 810, a worktable module is also connected to the main frame. Step 810 is represented by figures 21a, 21 b and 21c wherein storage wall 520 is connected to the main frame 202 and worktable module 530 is also connected to the main frame on an adjacent side.

Figure 22 shows a simplified example utility unit 1000b. Utility unit 1000b has the same base unit 200 as in the example utility unit 1000, supporting an upper part 400. Utility unit 1000b has detachably connected storage modules 420a, 420b which are configured to extend out of a rear vehicle opening. Further accessories, for example worktable module or wall frame 530b may be supported by attachment to a side of the modules 420. The unit 1000b is configured to be attached to a vehicle in which it is installed via pre-existing lashing points in the vehicle cavity. Utility unit 1000b is a simplified version of the utility unit of the invention, however, features of the example unit 1000b are interchangeable with features of the example unit 1000, except where clearly incompatible.

The utility unit described herein is a self-contained, modular system which maximises the limited useable space of the cavity in the back of a van. Each of the various modules are detachably attachable in any position on the base unit. The utility unit encourages even distribution of weight of items to be stored and/or transported in the van cavity. The main volume of the utility unit has dimension designed for the average smallest van types used in carpentry so that it is suitable for almost all types of van used in this industry. The utility unit has attachment means adaptable to the different sizes of van for suitability with almost all types of vans. Thus, the one unit of standard, fixed dimension can be installed within the majority of trade vehicles. This saves time, expense and improves quality assurance in comparison to custom designs for each individual van cavity. In particular, the partial pre-assembly of the utility unit significantly reduces assembly time.

In addition, the utility unit may have a minimum of a twofold extension orientation, utilising at least two openings to the van cavity. The result is an improved usage of the limited van cavity space and improved stability of the unit within the van.

Having described preferred examples of the invention it will be apparent to those skilled in the art that other embodiments incorporating the invention may be used. These and other examples of the invention illustrated above are intended by way of example only and the actual scope of the invention is to be determined from the appended claims.
