[0184] The present application relates to three primary concepts. The first concept relates to that of a pallet component and a corresponding geometry which provides fluid communication between a device chamber of the pallet component and atmosphere. A second concept relates to a pallet assembly which incorporates an electronic device which provides load sensing functionality, the electronic device being inserted into a device chamber, wherein an end face of the electronic device lies flush with a product supporting surface of the pallet. The third concept relates to a pallet component in which an aperture communicates with a plurality of adjacent internal chambers, such that a single aperture can provide drainage functionality for the adjacent internal chambers. Each of these concepts will be discussed in turn below.
[0185] FIG. 1 is a pallet assembly 2. The pallet assembly 2 comprises a pallet 4 with two electronic devices 6a, 6b inserted in the pallet 4.
[0186] The pallet 4 comprises a platform 8 and a plurality of skids 10a to 10c. The platform 8 is an example of a pallet component. Similarly, the skids 10a to 10c are examples of a pallet component.
[0187] As will be appreciated from the other Figures, the skids 10a-c are attached to the platform 8 via attachment portions. Specifically, each of the platform 8 and the skids 10a to 10c incorporate a plurality of respective attachment portions. When assembled, the attachment portions engage one another as shown in FIG. 1. This will be described in greater detail below.
[0188] Although not visible in FIG. 1, the platform 8 incorporates nine separate attachment portions. In the illustrated embodiment, the nine attachment portions are arranged in a 3×3 arrangement. Three attachment portions are at least partly visible in FIG. 1, labelled 12a-c. The attachment portions 12a-c of the platform 8 engage with corresponding attachment portions 14a-c of the skid 10a.
[0189] The platform 8 comprises a deck, the thickness of which is generally indicated by the reference numeral 16. Deck 16 comprises a product supporting surface 18. The product supporting surface 18 is a generally flat surface upon which goods, products or displays can be supported. A plurality of sidewalls 20a-d extend from a periphery of the product support surface 18. The sidewalls 20a-d define an outermost periphery of the deck 16.
[0190] Although not visible in FIG. 1, nine bayonets (visible in FIGS. 3a and 3b—labelled 36) secure the platform 8 to each of the three skids 10a-c. In FIG. 1 the bayonets are covered by caps, one of which is labelled 22a in FIG. 1. Neither the bayonets, nor the caps, are the subject of this application, although more detail regarding the bayonet fitting can be found in WO2013/120595.
[0191] Features of primary interest, having regard to the first concept, are that of one or more internal chambers. These internal chambers are disposed within the attachment portions of either or both of the platform 8 and skids 10a-c. Again, these will be described in detail below.
[0192] FIG. 2 is a close up perspective and cutaway view of a central block 24 of the pallet assembly 2 of FIG. 1. The central block 24 corresponds with the attachment portion located centrally about the platform 8. Specifically, FIG. 2 shows the electronic devices 6a, 6b, a portion of the product supporting surface 18, a central aperture 26 which is configured to receive a bayonet/cap as described above, and attachment portions 12e, 14e of the platform 8 and skid 10b respectively.
[0193] Much of the pallet assembly of FIG. 1 is cutaway in FIG. 2 such that the central block 24 is more clearly visible. As will be appreciated from the exposed ribs and lines of FIG. 2, lengths of the skid either side of the central attachment portion 14e have been removed. Similarly, all of the ribs surrounding the attachment portion 12e of the platform 8 have been removed such that a ribbed structure underneath the deck 16 is not visible. FIG. 3b and FIGS. 4 and 5 show, more clearly, the surrounding structure of the platform 8 and skid 10b which are normally present when the “cutaway” of FIG. 2 is not “applied”.
[0194] Each of the attachment portions 12e, 14e of the platform 8 and skid 10b respectively comprise a perimeter wall 28, 30. The perimeter wall forming part of the attachment portion 12e of the platform 8 is labelled 28, whilst the perimeter wall forming part of the attachment portion 14e of the skid 10b is labelled 30. Each of the perimeter walls 28, 30 surround one or more internal chambers within the attachment portions 12e, 14e. The arrangement of internal chambers, and their function, will be described below.
[0195] Also visible in FIG. 2 are cut-outs 32, 34. The cut-outs 32, 34 are part of the perimeter walls 28, 30 of each of the platform 8 and skid 10b. The cut-outs 32, 34 are semi-circular. As such, the cut-outs 32, 34 align to define an aperture which has the geometry of a circle. Cut-outs 32, 34 define a fluid pathway between internal chambers within the attachment portions 12e, 14e and atmosphere. That is to say, air can flow from the outside to within these chambers. In certain arrangements, and particularly where an electronic device 6a, 6b is present, the aforementioned fluid pathway can allow the electronic device 6a, 6b to sample environmental signals or conditions such as temperature and humidity. Furthermore, this functionality is provided whilst not unduly risking damage of the electronic device 6a, 6b from external impact and/or liquid ingress during cleaning processes such as (high pressure) jet washing. Detail regarding the fluid pathway, the various chambers and cut-outs is provided in the following description and accompanying Figures.
[0196] FIG. 3a is a close-up perspective cutaway view of the pallet for FIG. 1 indicating how the electronic device 6a is inserted.
[0197] FIG. 3a shows the platform 8 and the skid 10b. Also shown is the bayonet 36, and the cap 22a, which secures the platform 8 to the skid 10b.
[0198] As previously mentioned, the platform 8 comprises product supporting surface 18. The product supporting surface 18 incorporates two orifices 38a, 38b. The orifices 38a, 38b are openings via which the electronic device 6a, 6b is received. In the illustrated embodiment the orifices 38a, 38b are generally rectangular. However, other geometries of orifice could otherwise be used.
[0199] As shown in FIG. 3a, the attachment portions 12e, 14e of both the platform 8 and the skid 10b each comprise two device chambers. For ease of reference, the device chamber of the attachment portion 12e of the platform 8 is labelled 40a. The device chamber of the attachment portion 14e of the skid 10b is labelled 42a. The device chambers 40a, 42a, in use, align with one another and can therefore be considered to define a device enclosure 44a. That is to say, the device enclosure 44a is shared between the platform 8 and the skid 10b. As the pallet 4 is designed to house two electronic devices 6a, 6b, it logically follows that there are a pair of device enclosures 44a, 44b. The other device enclosure 44b is similarly defined by constituent device chambers 40b, 42b forming part of platform 8 and skid 10b respectively.
[0200] FIG. 3a therefore indicates the insertion of the electronic device 6a from above. Such a top-down insertion is desirable because the need to dismantle the pallet 4 is negated. Furthermore, should the electronic device 6a need to be removed from the pallet 4 for servicing reasons, this can again be achieved without dismantling the pallet 4.
[0201] Not visible in FIG. 3a are the cut-outs 32, 34 of the central block 24 as shown in FIG. 2. The cut-outs 32, 34 are one set of cut-outs which provide fluid communication between the atmosphere and the device enclosures 44a, 44b. The cut-outs provide the functionality that the electronic devices 6a, 6b disposed in the device enclosures 44a, 44b are able to fluidly communicate with the atmosphere. As mentioned, this can provide for environmental signals, such as temperature and humidity, to be sampled. Furthermore, and again as will be described in detail below, because the cut-outs 32, 34 do not provide direct fluid communication, the electronic devices 6a, 6b remain protected from undesirable liquid ingress such as, for example, water directed at the pallet 4 during a jet washing cleaning process. In other words, the cut-outs 32, 34 define part of a tortuous fluid pathway (i.e. not a direct fluid pathway) which allows for environmental signals to be sampled, via the airflow, whilst preventing undesirable liquid ingress, and so an associated risk of damage to the electronic device 6a, 6b, in use. That is to say, a jet of water, used as part of a cleaning process, may be prevented from directly entering the device enclosures 44a, 44b.
[0202] Further cut-outs which form part of the fluid pathway are labelled 46, 48. These cut-outs 46, 48 form part of the platform 8 and skid 10b respectively. Like the arrangement of cut-outs shown in FIG. 2, the cut-outs 46, 48 of FIG. 3a are semi-circular and align with one another to define a generally circular aperture. In the arrangement shown in FIG. 3a, and as will be described further below, the cut-outs 46, 48 are in direct fluid communication with the device chambers 40b and 42b. A further arrangement of cut-outs is shown adjacent the cut-outs labelled 46, 48, but these are not numbered for reasons of clarity. In preferred arrangements, four such cut-outs are present to provide direct fluid communication to each of the device chambers 40a, 40b, 42a, 42b. This will be described in more detail in connection with FIG. 4.
[0203] Returning to FIG. 3a, the device chamber 40a, forming part of the platform 8, further comprises a plurality of aligning ribs 50a-c. The aligning ribs may otherwise be described as projections and prevent excessive contact between the electronic device 6a and walls of the device chamber 40a during insertion of the electronic device 6a. As suggested by the name, the aligning ribs 50a-c also provide an aligning functionality in ensuring that the electronic device 6a is properly located within the device chamber 40a. Further advantages provided by separating the electronic device 6a from the surrounding walls is that the electronic device 6a is better protected from impacts to the central block 24, and the risk of damage to the electronic device 6a due to leakage of fluids along the surrounding walls is also reduced.
[0204] The aforementioned “extra” protection of the electronic device 6a is in addition to the fact that the electronic device 6a is disposed in the central block which is the best protected “block” of the pallet, owing to it not being exposed to side impacts (i.e. it is surrounded on all sides by other parts of the pallet 8). The central block is also typically the best protected block from handling and transport equipment through the supply chain. The central block location is also the most representative location, across the pallet deck, for sensing environmental signals, such as temperature, moisture and weight. That is to say, sensed signals are more representative of the general pallet condition when taken from the central block. Despite the above advantages of utilising the central block, the invention could otherwise be applied to any block around the pallet (e.g. the blocks adjacent, and surrounding, the central block).
[0205] Aligning ribs 50a-c preferably extend substantially parallel to the perimeter wall 28 as shown in FIG. 2. Although not described in detail, corresponding aligning ribs are provided in the other device chamber 40b in the platform 8.
[0206] Considering now the ribs in the device chamber 42a in the skid 10b, there are two separate varieties of rib present in this chamber. Firstly, like that described in connection with the device chamber 40a of the platform 8, in the device chamber 42a of the skid 10b there are a plurality of aligning ribs 52a, 52b which project from the perimeter 30. The aligning ribs 52a, 52b are substantially aligned with the corresponding aligning ribs 50a, 50b of the device chamber 40a of platform 8. However, unlike the previous device chamber 40a, the device chamber 42a incorporates a further variety of rib. Specifically, the device chamber 42a incorporates supporting ribs 54a, 54b. The supporting ribs 54a, 54b also project into the device chamber 42a. However, unlike the aligning ribs 50a, 50b, the supporting ribs 52a, 52b define a ledge. The ledge limits the extent to which the electronic device 6a can be inserted into the device enclosure 44a. The functionality of the ledge in use is best shown in connection with FIG. 3b, which shows the electronic device 6a seated within the device enclosure 34a.
[0207] Returning to FIG. 3a, the supporting ribs 54a, 54b are disposed between respective pairs of aligning ribs 52a, 54b. That is to say, a combination of the supporting rib, with an aligning rib at either end, may form a continuous wall. As shown in FIG. 3a, the supporting ribs 54a, 54b each incorporate cut-outs 56a, 56b. The cut-outs 56a, 56b are semi-circular. In use, the cut-outs 56a, 56b enable fluid to flow underneath the electronic device 6a (see FIG. 3b).
[0208] Turning to FIG. 3b, which is a perspective view of the pallet 4 of FIG. 3a with the electronic device 6a inserted therein, interaction between various features and the electronic device 6a is more clearly illustrated. As with FIG. 3a, FIG. 3b shows the platform 8 and skid 10b attached to one another by the bayonet 36 and cap 22a. It is noted that there is a gap indicated between the end of the bayonet 36 and the cap 22a, but for the purposes of this application, the exact mechanism used to secure the two pallet components together is not of relevance.
[0209] As mentioned above, the supporting ribs 54a, 54b define a ledge which defines a lower limit of travel of the electronic device 6a. Furthermore, cut-outs 56a, 56b in the supporting ribs allow fluid to flow underneath the electronic device 46a. An adjacent empty device enclosure 44b shows more clearly the relationship between the supporting rib and the aligning rib in the attachment portion 14e of the skid 10b.
[0210] Also shown more clearly in FIG. 3b is the surrounding structure of both the platform 8 and the skid 10b which surrounds the respective attachment portions 12e, 14e. These are the same structures which are removed from the isolated view of FIG. 2.
[0211] The retention means which secures the electronic device 6a to be pallet 4, specifically the product supporting surface 18 thereof, is also shown in FIG. 3b. In the illustrated example, two remaining clips (only one of which is visible in FIG. 3b) 58a engage corresponding catches in the product supporting surface 18. Only one catch 60a is visible in FIG. 3b. The combination of the clips 58a and catch 60a allow the electronic device 6a to be snap fitted into the product supporting surface 18, and so the pallet 4. The electronic device 6a could otherwise be said to snap fit into the platform 8. The clips 58a provide for a tool-less insertion and can be integrally moulded into the chassis of the electronic device 6a.
[0212] Insertion of the electronic device 6a to the extent shown in FIG. 3b is advantageous because an end face 62 of electronic device 6a lies substantially flush with the product supporting surface 18. This is desirable for a number of reasons including reducing interruption to the product supporting surface 18, and being able to more readily utilise the electronic device 6a for load sensing capability. Specifically, having the end face 62 of the electronic device 6a lie flush with the product supporting surface 18 means that the electronic device 6a can more readily sense loads placed upon the product supporting surface 18. The electronic device 6a can sense loads by way of, for example, a strain gauge incorporated at least partly in the end face 62 of the electronic device 6a. This provides useful functionality such as being able to monitor stock levels and the distribution of stock on the product supporting surface 18. The end face 62 may be referred to as an upper surface of the electronic device 6a. The end face 62 may be said to form part of an integrated lid or cap of the electronic device 6a.
[0213] Turning to FIG. 4, a magnified view of an underside of the platform 8 is provided. In particular, a close-up view of the attachment portion 12e is provided.
[0214] In FIG. 4 the perimeter wall 28, and the plurality of internal chambers which it surrounds, are more clearly illustrated.
[0215] In this example, the perimeter wall 28 is a single continuous wall which is substantially square with rounded corners. However, alternative geometries of perimeter wall are possible, and the perimeter wall could instead be formed of a number of discrete perimeter wall sections (i.e. not be continuous). FIG. 4 shows the rib structure which surrounds the perimeter wall 28 and which has been removed from the central block 24 shown in FIG. 2. An underside of the central aperture 26 is also clearly visible in FIG. 4.
[0216] The perimeter wall 28 comprises a plurality of cut-outs. These cut-outs may be referred to as perimeter wall cut-outs 32a, 32b. In use, the perimeter wall cut-outs 32a, 32b enable one or more internal chambers to fluidly communication with the external atmosphere. That is to say perimeter wall cut-outs 32a, 32b enable fluid to breach the perimeter wall 28. It is noted that the positions of the perimeter wall cut-outs 32a, 32b differ from the positions of the cut-out 32 of FIG. 2. Specifically, the perimeter wall cut-outs 32a, 32b are generally disposed at opposite corners of the square geometry defined by the perimeter wall 28. In contrast, the cut-out 32 is disposed along a midpoint of a wall section of the perimeter wall 28 in FIG. 2. The specific positions of the cut-out(s) along the perimeter wall may not be of particular relevance to the invention. As such, the positions of the cut-out of either FIG. 4 or FIG. 2 would be suitable. However, in connection with FIG. 4, and as will be described in more detail below, it is advantageous to have a plurality of perimeter wall cut-outs which are distanced from one another. Also preferable is that the perimeter wall cut-outs are disposed on opposite sides of the perimeter wall. This is so that any sampling of environmental conditions provides a more reliable average between two locations and such that the readings are not significantly affected should one of the cut-outs become either blocked or disposed in an otherwise biasing condition (e.g. in an exhaust flow or some other unrepresentative hot/cold ‘spot’).
[0217] The position of the perimeter wall cut-outs 32a, 32b can provide further functionality in that they can ‘direct’ external water jets towards particular walls. That is to say, a central axis of the perimeter wall cut-out(s) may be aligned with a partition wall. More preferably, the central axis is offset from any (other) cut-outs. This is indicated in FIG. 4 by the arrow 33, which represents a water jet from a cleaning process. Because of the alignment of the perimeter wall cut-out 32b, the jet 33 does not impinge, or penetrate, a partition wall cut-out 38c. Most of the liquid from the jet 33 will therefore be retained within the boundary of the corresponding corner chamber (i.e. will not reach the device chamber). Said retained liquid can then exit the corner chambers via corresponding drainage holes in the corresponding chambers in the skid 10b, by gravity. This further assists in reducing undesirable liquid leakage into the device chambers. The same functionalities are provided by the other perimeter wall cut-out 32a.
[0218] As described in connection with FIGS. 3a and 3b, the attachment portion 12e comprises two device chambers 40a, 40b. For ease of reference, the device chambers 40a, 40b will be referred to as a first device chamber 40a and a second device chamber 40b respectively. As described in connection with FIGS. 3a and 3b, each of the device chambers 40a, 40b are configured to at least partially receive an electronic device therein. Furthermore, and as will be numbered only in connection with the first device chamber 40a, each of the device chambers comprises a plurality of aligning ribs 52a-d. Aligning ribs 52a-d are provided as opposing pairs of ribs.
[0219] As will be appreciated from FIG. 4, as well as the central aperture 26 and two device chambers 40a, 40b which are disposed within the perimeter wall 28, there are a number of other chambers also disposed within the perimeter wall 28. Specifically, in the illustrated arrangement there is a corner chamber disposed at each rounded corner of the perimeter wall 28. Furthermore, there are four central chambers disposed around the central aperture 26. The various chambers are defined at least in part by either the perimeter wall 28, central aperture 26, device chambers 40a, 40b and/or further partition walls. Many of the various chambers and/or walls further incorporate cut-outs to provide fluid communication between the external atmosphere and the device chambers 40a, 40b. These cut-outs define the fluid pathway which penetrates the perimeter wall 28 and allows environmental signals to be sampled.
[0220] Beginning with the first device chamber 40a, this chamber comprises four cut-outs 64a-d. These cut-outs 64a-d may be referred to as device chamber cut-outs, owing to their position. The device chamber cut-outs 64a-d are arranged in a cut-out array along one long side of the device chamber 40a. Like cut-outs are provided in the second device chamber 40b, these cut-outs are labelled 65a-d.
[0221] As illustrated in FIG. 4, a number of partition walls are also present in the attachment portion 12e. For the purposes of this document, the partition wall is intended to refer to any wall, within the perimeter wall 28, which does not define either of the device chambers 40a, 40b. Partition walls are therefore indicated with reference numerals 66a-f. Partition walls 66a, 66b, 66d and 66e at least partly define corner chambers within the attachment portion 12e. Said partition walls define the corner chambers in co-operation with at least one wall which defines either of the device chambers 40a, 40b. Central partition walls 66c and 66f each extend from an opposing side of the perimeter wall 28 up to the central aperture 26. The central partition walls 66c, 66f are examples of partition walls.
[0222] As will be appreciated from FIG. 4, some of the partition walls 66a-f also incorporate cut-outs 68a-d. The cut-outs 68a-d, which may be referred to as partition wall cut-outs, at least partially define the fluid pathway between the atmosphere and the device chambers 40a, 40b.
[0223] An example fluid pathway is indicated with reference numeral 70 in FIG. 4. As will be appreciated from the dashed line, the fluid pathway 70 begins at the perimeter wall cut-out 32a, and then passes through partition wall cut-out 68a (a cut-out in the partition wall 66b in closest proximity to the perimeter wall cut-out 32a). At this point, the pathway separates and either enters the first device chamber 40a via device chamber cut-outs 64c and also 64d, or continues to flow towards a further partition wall cut-out 68b in central partition wall 66c. From this point, that flow then again enters second device chamber 40b via device chamber cut-outs 66c and/or 66d.
[0224] Further features shown in FIG. 4 are those of chamfers 72a, 72b disposed along portions of the perimeter wall 28. The chamfer may otherwise be referred to as a leakage reducing chamfer. The chamfers 72a, 72b are provided along portions of the perimeter wall 28 which are adjacent to the device chambers 40a, 40b. That is to say, the chamfers 72a, 72b occupy lengths of the perimeter wall 28 which are directly disposed between the device chambers 40a, 40b and the atmosphere. The chamfers 72a, 72b assist with reducing unwanted liquid leakage (specifically water ingress) into the device chambers 40a, 40b. This is achieved by the chamfers 72a, 72b providing a tortuous path between an external side of the perimeter wall 28 and the device chambers 40a, 40b. This can assist in protecting any electronic device inserted into the device chambers 40a, 40b against damage from, for example, processes such as jet washing (i.e. cleaning the pallet).
[0225] By providing the chamfers 72a, 72b along only the portions of the perimeter wall 28 which are most susceptible to providing a leakage path to the electronic devices inserted in the device chambers 40a, 40b, the material usage and cost is kept to a minimum whilst the device chambers 40a, 40b remain protected.
[0226] Overall, from FIG. 4 it will be appreciated that the various walls, device chambers and cut-outs cooperate to provide an arrangement which defines a fluid pathway to substantially prevent liquid ingress into the device chambers whilst allowing electronic devices to sample temperature and/or humidity, among other variables. Put simply, gases (such as air) can enter the device chambers, whilst liquids (such as water) generally cannot. The fluid pathway may therefore otherwise be referred to as an airflow pathway. Furthermore, this is achieved in a low cost and really manufactured fashion due to the arrangement of the cut-outs.
[0227] It is noted that all of the cut-outs of FIG. 4 are disposed in an end face of the respective wall. This is a particularly simple geometry to manufacture because the cut-outs can be present during the injection moulding process i.e. they do not need to be created by drilling bores in already formed material. However, in other arrangements, the cut-outs may take the form of apertures drilled through the prospective chambers and/or partition walls. The end face of the walls may be referred to as a partition face, owing to two abutting end faces defining a partition line between two adjacent components.
[0228] FIG. 5 is a perspective view of a portion of a skid 10b in accordance with the invention. The skid 10b comprises attachment portion 14e and support portion 74. As explained above, the skid 10b is an example of a pallet component. Where the pallet component is a skid 10b, the support portion 74 is for, or configured to, support the skid on a surface.
[0229] Also shown in FIG. 5 is the perimeter wall 30 of the attachment portion 14e. A central aperture 76 extends through the attachment portion 14e. The central aperture 76 of the skid 10b aligns with the central aperture 26 of the platform 8.
[0230] Also shown in FIG. 5 are the device chambers 42a, 42b. Finally, various partition walls, and device chamber walls, are also shown in FIG. 5 (but are not labelled). As will be appreciated from FIG. 5, the various partition walls and device chamber walls project beyond the perimeter wall 30 in a vertical direction. This is in contrast to the partition walls 66a-f and device chamber walls of FIG. 4 which are recessed relative to the perimeter wall 28. It will be appreciated that this arrangement provides for an abutment of the respective partition walls and device chamber walls at a position which is vertically offset from that of the point where the perimeter walls 28, 30 meet. This further improves the resistance of the device chambers to the ingress of fluid, owing to the more tortuous path which any fluid must traverse in order to reach the device chambers from outside the respective attachment portions 12e, 14e. More detail regarding the arrangement of walls and device chambers, and cut-outs incorporated therein, is provided in connection with FIG. 6.
[0231] A distinction between the arrangements shown in FIGS. 4 and 5 is that, in FIG. 5, the perimeter wall 30 does not incorporate any cut-outs. Instead, cut-outs are disposed in partition walls 43a-fand walls 45a, 45b defining the device chambers 42a, 42b. Four such cut-outs are numbered 47a-d in wall 45a.
[0232] It will be appreciated that the aforementioned walls 43a-f, 45a, 45b, specifically cut-outs therein, define at least part of a fluid pathway between the device chambers 42a, 42b and the atmosphere in use. When the attachment portion 14e of the skid 10b engages a corresponding attachment portion 12e of the pallet 8, the perimeter wall 30 of the skid 10b abuts the perimeter wall 28 of the platform 8. Cut-outs 32a, 32b (see FIG. 4) in the perimeter wall 28 of the platform 8 therefore enable an interior of the attachment portions 12e, 14e to fluidly communicate with external atmosphere. In this instance, interior is intended to mean a region inboard of the perimeter wall. The other cut-outs in the attachment portions 12e, 14e in both the skid 10b and platform 8 then allow the device chambers 40a, 42a, 40b, 42b (which define device enclosures 44a, 44b) to fluidly communicate with external atmosphere. Cut-outs in a perimeter wall may therefore only be incorporated in one pallet component (i.e. one of the platform 8 or the skid 10b). Similarly, cut-outs in the other walls may only be incorporated in one pallet component. Alternatively, cut-outs may be provided in both pallet components, or distributed between the pallet components (i.e. one pallet component may incorporate some cut-outs, whilst the other pallet component incorporates other cut-outs).
[0233] FIG. 6 is a close up perspective cutaway view of the skid 10b of FIG. 5 with an electronic device 6a received in the first device chamber 42a. Many of the features of the attachment portion 14e of the skid 10b are the same as those described in detail in connection with the attachment portion 12e of the platform 8 of FIG. 4. As such, detailed description in connection with FIG. 6 will not be provided. However, of note, once again a plurality of partition walls, and device chamber walls, with cut-outs therein provide fluid communication via a fluid pathway between atmosphere and one or more device chambers surrounded by the perimeter wall 30. A chamfer 78a is incorporated along a portion of the perimeter wall 30 adjacent the second device chamber 42b. This chamfer 78a cooperates with a corresponding chamfer 72a of the platform 8 to provide a tortuous path which was described in connection with FIG. 4 (i.e. it assists in [greatly] reducing liquid ingress).
[0234] Turning to FIG. 7a, a further embodiment of the invention is illustrated. In FIG. 7a, a partially cutaway perspective view of a central block of a half pallet 100 is shown. The half pallet 100 comprises a platform 102 and a skid 104. The platform 102 is formed of a deck 106, which comprises a product supporting surface 108, and an attachment portion 110. Like that of the attachment portion described in connection with the previous embodiment, attachment portion 110 is configured to engage a corresponding attachment portion of another pallet component, in this instance an attachment portion 112 of the skid 104. FIG. 7a may be said to show a pallet assembly, owing to the presence of the electronic device 6a inserted in the pallet 100.
[0235] Beginning with the platform 102, like the platform 8 described in connection with the previous embodiment, the platform 102 comprises an orifice 114 in the product supporting surface 108. This orifice 114 provides an opening through the product supporting surface 108 into a device chamber 116. The device chamber 116 is configured to receive an entirety of the electronic device 6a. The device chamber 116 therefore fully receives the electronic device 6a. This is a distinction between the previous embodiments in which the perspective device chambers only received part of the electronic device 6a. Furthermore, unlike the previous embodiment only one orifice 114 is provided in the product supporting surface 108. This may be due, at least in part, to the platform 102 being smaller than the platform 8, and thus less space being available for the incorporation of any electronic devices.
[0236] The attachment portion 110 of the platform 102 is defined by a perimeter wall 118 in the same manner as the previous embodiment. As with the previous embodiment, the perimeter wall 118 comprises a cut-out 120 which defines a fluid pathway between the device chamber 116 and the external atmosphere. The exact route of the fluid pathway will be described in connection with the other figures.
[0237] Returning to FIG. 7a, and focussing on the skid 104, the skid 104 also comprises the attachment portion 112. The attachment portion 112 is defined, at least in part, by a perimeter wall 122. The perimeter wall 122 surrounds a plurality of internal chambers, two of which are labelled with reference numerals 124a and 124b. In this embodiment, the internal chambers 124a, 124b do not receive any part of the electronic device 6a. Instead, these internal chambers 124a, 124b merely provide a support structure and tortuous path (i.e. not a direct path) to reduce the likelihood of fluid ingress into the device chamber 116.
[0238] The perimeter wall 122 comprises a cut-out 126, this cut-out again defining, when assembled, a fluid pathway between the device chamber 116 and the atmosphere.
[0239] FIG. 7b shows the pallet 100 of FIG. 7a without the electronic device 6a inserted in the device chamber 116 thereof. Clearly visible in FIG. 7b is the orifice 114 in the product supporting surface 108 of the platform 102. The interior of the device chamber 116 is also more clearly visible.
[0240] As mentioned in connection with FIG. 7a, the device chamber 116 fully receives an electronic device 6a therein. Put another way, the device chamber 116 defines, in isolation, the device enclosure. The device chamber 116 is generally cuboidal. That is to say, the device chamber 116 generally has the shape of a cuboid with one open end i.e. the orifice 114. The device chamber 16 comprises a plurality of alignment features 128a-c (further alignment features are not visible in FIG. 7b). The device chamber 116 comprises a cut-out 130 which is disposed in a base 132 of the device chamber 116.
[0241] From FIG. 7b it should be noted that the perimeter wall 118 extends beyond (specifically, below) the base 132 of the device chamber 116. For the purpose of this document, this is still considered to fall within the definition of the perimeter wall 118 surrounding the device chamber 116.
[0242] The way in which the electronic device 6a is snap fitted into the platform 102 is the same as for the previous embodiment.
[0243] FIG. 7b also indicates how the cut-out 126 in the perimeter wall 122 of the attachment portion 112 provides fluid communication across the perimeter wall 122. Specifically, the cut-out 126 is an aperture in the perimeter wall 122 and provides fluid communication between the atmosphere and the internal chamber 124b adjacent the cut-out 126. The cut-out 126 defines, in combination with the cut-outs 120 and 130 of the platform 102, the fluid pathway.
[0244] FIG. 7c is a perspective cutaway view of an underside of the pallet 100 of FIG. 7a. Electronic device 6a is shown received by the device chamber 116. FIG. 7c shows how the skid 104 further comprises a number of other cut-outs 134a, 134b.
[0245] The cut-outs 134a, 134b are disposed through a base 136 of the attachment portion 112 of the skid 104. In the base 136, the cut-outs 134a, 134b are in the form of apertures, or bores. These apertures 134a, 134b also provide drainage functionality in that any liquid present in the one or more internal chambers is able to pass through the apertures 134a, 134b to exit the skid 104. The apertures 134a, 134b therefore provide openings through which liquid can be evacuated. FIG. 7c also shows an underside of the base 132 of the device chamber 116. Also shown extending beyond the base 132 is perimeter wall 118 (at least a portion thereof) which comprises cut-out 120.
[0246] A feature not previously illustrated is that of an underside of the cut-out 130 (i.e. the drainage hole) in the base 132 of the device chamber 116. As shown in FIG. 7c, the cut-out 130 opens out into a boss 137 which guides liquid away from the device chamber 116, allowing it to exit the skid.
[0247] FIG. 8 is a close up perspective view of part of the skid 104 of FIGS. 7a-c. FIG. 8 primarily shows the attachment portion 112 from above.
[0248] As described in connection with the previous figures, the attachment portion 112 is defined, at least in part, by a perimeter wall 122. In use, the attachment portion 112 engages a corresponding attachment portion of a platform. As will be appreciated from FIG. 8, the perimeter wall 122 is not necessarily an outermost wall of the attachment portion 112. Instead, the attachment portion 112 may further comprise a ledge, lip or further extent of material which projects beyond the perimeter wall 122. In FIG. 8, such a lip is labelled 138. As will be appreciated from FIGS. 7a and 7b, it may be the lip 138 specifically which engages the attachment portion of the platform. Also as indicated in FIG. 7b, the perimeter wall 122 is not necessarily exposed once the pallet 100 is assembled. That is to say, in use, the perimeter wall 122 may be enclosed by one or more other components (such as, for example, a perimeter wall of an adjacent pallet component). Returning to FIG. 8, the perimeter wall 122 may define an outermost perimeter of at least a part of the attachment portion 112. In FIG. 8, the perimeter wall defines an outermost perimeter of an upper portion of the attachment portion 112 (i.e. that above the aforementioned lip 138).
[0249] Internal chambers surrounded by the perimeter wall 122 are visible in FIG. 8. In total, there are eight separate chambers distributed within the perimeter wall 122. It will also be appreciated that in the embodiment shown in FIG. 8 the perimeter wall 122 is formed of two C-shaped structures. As such, the perimeter wall 122 may not necessarily be a continuous wall but can instead be formed of a plurality of wall sections, like that shown in FIG. 8.
[0250] The base 136 of the attachment portion is also visible in FIG. 8. Furthermore, the base 136 is shown with cut-outs in the form of apertures 134a-d extending there through.
[0251] Perimeter wall 122 comprises cut-outs 126a-d. Cut-outs 126a-d provide fluid communication through, i.e. across, the perimeter wall 122 between the atmosphere and one of four adjacent internal chambers. Said four internal chambers surround a central aperture 140.
[0252] FIG. 9a is a perspective view of the electronic device 6a. The electronic device 6 can be said to comprise a body 63 and a cap 61.
[0253] As mentioned earlier in the document, references to the electronic device 6a may be to a combination of a chassis (i.e. the body 63 and the cap 61) and one or more electronic components housed therein.
[0254] The end face 62 is flat such that, when the electronic device 6a is inserted into the device chamber, the end face 62 is flush with the product supporting surface of the pallet. The end face 62 may be said to form part of the cap 61.
[0255] The cap 61 may, as suggested, close an otherwise open cavity defined by the body 63 of the device 6a. Alternatively, the cap 61 and body 63 may be integrally formed with one another.
[0256] Clips 58a, 58b, formed as part of the cap 61, are used to secure the electronic device 6a in position in the device chamber. The clips 58a, 58b are advantageously integrally formed with the cap 61. The clips 58a, 58b provide a snap-fit functionality which allows the electronic device 6a to be inserted without requiring tools.
[0257] In preferred arrangements, the electronic device 6a provides load sensing functionality. That is to say, the electronic device 6a may be able to sense a load placed upon the product supporting surface. The electronic device 6a may also be able to sample environmental signals, such as temperature and humidity.
[0258] FIG. 9b is a front view of the electronic device 6a.
[0259] The electronic device, including the cap, may be around 120 mm in height, around 85 mm wide and around 35 mm in depth. More specifically, the electronic device may have the following dimensions: 122 mm height by 86 mm width by 33 mm depth. The major width and depth dimensions may be defined by the cap of the electronic device. A portion of the electronic device extending from the cap may be around 120 mm in height by around 60 mm in width by around 25 mm in depth. More specifically, the portion may have dimensions 117 mm height by 62 mm width by 25 mm depth. The portion may refer to the body of the device.
[0260] The device chambers may be around 65 mm in width by around 25 mm in depth. More specifically, the device chambers may be around 63 mm wide by around 26 mm depth. This provides a small clearance around an outside of the portion of the electronic device which extends from the cap, in-situ. It will be appreciated that the orifices are have a larger cross-section to receive the cap. In this way, a substantially continuous product supporting surface is maintained across the cap.
[0261] The electronic device(s) in this document may be a combination of one or more electronic components disposed in a housing. The housing may be formed of a cap or lid, and a body portion extending therefrom.
[0262] FIG. 10a is a plan view of (some of) the portion of the skid 10b shown in FIG. 5. In FIG. 10a, a laterally projecting support portion (as shown in FIG. 5) is omitted. As such, FIG. 10a shows only a central “block” portion of the skid 10b (i.e. that bound by the perimeter wall 30).
[0263] FIG. 10a illustrates a further concept disclosed in the present application. The further concept is the use of a single aperture to serve, or communicate with, a number of different internal chambers. This is advantageous for a number of reasons but particularly when the aperture is used for drainage. The single aperture can provide drainage functionality for a number of internal chambers, reducing the number of apertures which need to be provided. Reducing the number of apertures is desirable because the presence of more apertures can reduce the robustness of the pallet component.
[0264] As mentioned, FIG. 10a is a plan view of a portion of the FIG. 5 arrangement. As such, many features shared in common with FIG. 5 will not be described in detail. However, for completeness, FIG. 10a illustrates the attachment portion 14e, perimeter wall 30 and device chambers 42a, 42b. Also illustrated are partition walls 43a-f, and device chamber walls 45a, 45b.
[0265] The plan view of FIG. 10a shows an arrangement of apertures provided in a surface 49 of the skid 10b. The surface 49 is an internal surface bound by the perimeter wall 30. The surface 49b can be said to oppose an outer surface of the skid 10b (i.e. that shown in FIG. 10b, and the surface upon which the skid 10b rests in use).
[0266] Returning to FIG. 10a, there are a number of apertures provided in the surface 49. Three apertures 51, 53 are disposed within each of the device chambers 42a, 42b. These apertures 51, 53 allow liquid within the device chambers 42a, 42b to drain out of the chambers and thus exit the component altogether.
[0267] The apertures of particular interest are labelled 55a-d in FIG. 10a. Each of the apertures 55a-d are intersected, or partially divided, by a respective partition wall. For example, the lower left-hand aperture 55a is intersected by a corresponding lower left-hand partition wall 43b. By virtue of the intersection, the apertures 55a-d each communicate with at least two internal chambers defined, at least in part, by respective partition walls 43a, 43b, 43d, 43e. The partition walls 43a, 43b, 43d, 43e which intersect respective apertures 55d, 55a, 55b, 55c are referred to as dividing walls, owing to these walls defining, at least in part, at least two adjacent internal chambers. For example, the lower left-hand partition wall, or dividing wall, 43b defines, at least in part, two adjacent internal chambers 57a, 57b.
[0268] Advantageously, by having each of the apertures 55a-d in communication with at least two different adjacent internal chambers, any liquid which enters the chambers can drain out of the pallet component via the common aperture. The number of apertures required for an array, or arrangement, of internal chambers is therefore lower than would otherwise be required.
[0269] Although not visible in FIG. 10a, FIG. 10e illustrates how the dividing wall 43b does not penetrate the aperture 55a in the illustrated arrangement. Instead, the dividing wall 43b is adjacent the aperture 55a, or lies out of the plane of the aperture 55a. However, in other arrangements, the dividing wall may penetrate the aperture.
[0270] Turning to FIG. 10b, a view from underneath the portion of the skid 10b of FIG. 13a is provided. FIG. 10b also shows outer surface 59, which opposes the surface 49. The outer surface 59 can be considered to form part of a support portion, owing to the outer surface 59 abutting an external surface upon which the skid 10b rests in use. The nature of the intersections of the apertures 55a-d by dividing walls 43a, 43b, 43d, 43e are also shown in FIG. 10b.
[0271] As shown in FIG. 10b, the apertures 51, 53, 55a-d are all hexagonal. Furthermore, intersected apertures 55a-d are larger in cross-section than the apertures 51, 53. However, it will be appreciated that a variety of aperture geometries, arrangements and relative sizes of apertures, and dividing walls, can otherwise be utilised.
[0272] FIGS. 10c and 10d are angled perspective views of the FIG. 10a arrangement. These Figures are included to show the arrangement of the dividing walls, with respect to the apertures, in three dimensions.
[0273] FIG. 10e is a magnified view of part of the underside of the arrangement shown in FIG. 10b, shown as an angled perspective view. FIG. 10e illustrates the aperture 55a being provided in the surface (not visible in FIG. 10e) and extending through to the opposing outer surface 59. The offset, or adjacent, nature of the dividing wall 43b, relative to the aperture 55a, is also demonstrated in FIG. 10e. That is to say, FIG. 10a shows that the dividing wall 43b does not penetrate the aperture 55a. Instead, the dividing wall 43b lies out of the plane of, or is disposed adjacent to, the aperture 55a.
[0274] FIG. 11 is an alternative illustration of the portion shown in FIG. 10b, with part of a laterally extending support portion 67 indicated schematically.
[0275] For the purposes of the following Figures, i.e. FIGS. 12 to 19, the numbering and naming of features equivalent to those illustrated and described in connection with FIGS. 1 to 11 will be restarted. That is to say, like features from the following Figures, which are also shown in the preceding Figures, may be identified using a different feature name and/or reference numeral.
[0276] FIG. 12 shows a pallet 10 according to one preferred embodiment of the invention, in a perspective plan view. The pallet 10 is made of plastic, more specifically has been produced from a thermoplastic in an injection-moulding method. However, comparable pallets could just as well be produced by other casting methods, for example in the rotational moulding method. The pallet 10 has in principle an upper deck 12 which forms the loading surface 14 of the pallet 10, and on the underside thereof a number of feet 16 (in this case nine). The feet 16 form access openings on all sides, by virtue of which the illustrated pallet 10 can be effortlessly handled by the known stacking and transporting devices (forklift trucks). In the illustrated example, the feet 16 are connected by skids, which gives the pallet 10 additional stability and makes it suitable for roller conveyors, automatic conveyor systems and high-bay warehouses.
[0277] The Pallet 10 has, as shown in FIG. 12, a flat surface on the upper deck 12, on the side faces and on the undersides of the skids 16. It is thus easy to load and to clean. Instead of corners, roundings are preferably provided, which are advantageous for transport purposes. Despite this outwardly smooth surface of the pallet 10, it is desirable to be able to incorporate a rib structure/ribbing 44 (see FIG. 13) in the pallet 10, since this leads to an increase in mechanical stability while at the same time saving weight. For the sake of better clarity, only a few ribs have been provided with the reference sign 44. To this end, the pallet 10 shown in FIG. 12 is of two-part design. More specifically, the upper deck 12 is injection-moulded as a kind of pallet main body and the skids/feet 16 are injection-moulded as a separate part or multiple separate parts and then are connected to the upper deck 12. In this way, the rib structure 44 can be formed on the sides of the upper deck 12 and of the skids 16 which are in each case located on the inner side in the assembled state of the pallet 10, while the outwardly facing surfaces are kept smooth/flat. From a manufacturing point of view, this has the advantage that the rib structure 44 can be created without forming undercuts, which hinder removal from the mould.
[0278] FIG. 13 shows the rib structure 44 on the (inwardly facing) underside of the upper deck 12. Advantageously, the upper deck 12 and the feet 16 of the pallet 10 have identical/complementary ribbings which, when the upper deck 12 and the feet 16 are connected, come to bear against one another, enable a transmission of force and ensure a high strength and bending stiffness of the pallet. The ribbing extends largely in a cross-shaped manner in the underside of the upper deck 12 shown in FIG. 13, but it could also be configured for example in a honeycomb shape. In the region of the feet 16, however, preference is given to a cross-shaped (orthogonal) arrangement of the ribs so as to define a receptacle for a built-in electronic component, as will be described in detail below.
[0279] For connecting the upper deck 12 to the feet/skids 16, in the illustrated exemplary embodiment a bolt connection is provided. To this end, each of the feet 16 of the pallet has a bolt receptacle 28. As can clearly be seen in FIGS. 3 and 4, the bolt receptacle 28 extends perpendicular to the upper deck 12 through the foot region of the upper deck and the foot 16 arranged on the underside thereof. By way of a thread 30 and a support shoulder 32, the upper deck 12 and the foot 16 are clamped to one another by a bolt 34. The bolt receptacle 28 is closed at the top by a bolt receptacle cover 36, which prevents dirt or liquid from accumulating in the bolt receptacle 28. As can clearly be seen in FIG. 15, centring aids/centring aid structures 38 are formed in the joining regions between the upper deck 12 and the feet 16. The design of the centring aids/centring aid structures 38 is such that the rib structure 44 of one joining part protrudes somewhat, while that of the other joining part is set back somewhat, so that the rib structure 44 of one joining part (here of the foot 16) penetrates into the other joining part and thus defines in a form-fitting manner the relative positioning of the two joining parts in the direction of extension of the loading surface 14.
[0280] The pallet 10 according to the invention has a receptacle 18 for a built-in electrical/electronic component (not shown), such as for example a transponder or a sensor units. More specifically, two such receptacles 18 are formed, which are each formed in the region of the central foot of the pallet 10. The receptacles 18 are recessed into the upper deck 12 in a pocket-like manner, that is to say are closed towards the underside of the pallet 10, and form a substantially cuboidal cavity, wherein the exact shape of the receptacle 18 can of course be varied, depending on the built-in part. The opening of the receptacles 18 on the loading surface side can be closed by a cover 20, as shown for example in FIG. 12. The cover 20 may be clipped or welded. In the illustrated example, the cover is clipped and to this end the upper deck has latching cutouts 40, which are shown in FIG. 14. An indentation 42 extending around the edge of the opening of the receptacle 18 makes it possible for the cover 20 to terminate flush with the loading surface of the upper deck 12 in the installed state.
[0281] Since the receptacle 18 is closed at the bottom and is closed on the loading surface side by the cover 20, this effectively prevents splashing water or other liquids from penetrating into the receptacle 18 from outside and compromising the function of any built-in components. In order to avoid any condensation of the air enclosed in the receptacle 18, apertures 22 which act as ventilation holes are formed in the vertical side walls of the receptacle 18. The apertures 22 additionally have the advantage that temperature differences from outside are more rapidly transmitted if a temperature sensor is inserted in the receptacle 18. The apertures/ventilation holes 22 extend in the horizontal direction (parallel to the loading surface) towards a chamber 24 adjacent to the receptacle 18 in the interior of the pallet 10, more specifically in the interior of the foot 16. The embodiment shown in the figures accordingly has two such adjacent chambers 24 (one per receptacle 18). The adjacent chambers 24 can advantageously be created by the construction of the rib structure 44. The adjacent chambers 24 each have two outlet holes 26 on the bottom side of the foot 16 in which they are arranged, said outlet holes being clearly visible in FIG. 17 or 19, for example.
[0282] FIGS. 18 and 19 show the upper deck-side half and the foot-side half of the central foot 16 in which the two receptacles 18 are integrated. The inner workings of the central foot 16 can thus be clearly described on the basis of these diagrams. It can be seen that many of the ribs 44 which come into contact with one another during the joining-together have cutouts 43 towards the joining zone/interface, so that all the cavities formed by the rib structure 44 can enter into gas exchange with one another. Additional ventilation holes 48, which are shown in FIG. 18, are provided in the outer wall 46 of the central foot in order to provide a further improved air circulation within the foot 16. In the illustrated example, the ventilation holes 48 are arranged in corner regions of the foot and open into corner chambers 45, which are connected via cutouts 43 to the chambers 24 adjacent to the receptacle 18.
[0283] The above-described construction avoids any penetration of splashing water through the apertures/ventilation holes 22, since the receptacles 18 are not directly connected to the surrounding environment. At the same time, however, an effective ventilation of the receptacle 18 is provided via the outlet openings 26 and the ventilation holes 48. To further improve the air circulation within the receptacle 18, spacers 27 are provided on the side walls and also on the bottom of the receptacle 18, which spacers prevent a built-in component inserted therein from bearing against one of the walls. As can be seen in FIGS. 18 and 19, for example, the spacers 27 are configured as ribs 27 which extend along the walls bounding the receptacle 18. As shown in FIG. 19, the spacers 27 can in turn have indentations 50 towards the built-in electronic component, so that no chamber formation occurs due to the spacers 27.
[0284] In the preferred embodiment shown, the apertures/ventilation holes 22 are formed at the interface between the upper deck 12 and the feet 16 fastened thereto. This enables an integral manufacture of the ventilation holes 22 during the injection moulding, without additional undercuts being created, even though the ventilation holes 22 extend transversely to the direction of removal from the mould. As can be seen for example in FIGS. 14 and 15, in the illustrated embodiment of the invention the ventilation holes 22 are configured as complementary semicircular cutouts on the rib edges of the upper deck 12 and of the feet 16 that come into contact with one another. A circular shape offers little impairment of mechanical stability, for example caused by notching, while providing a relatively large passage surface area.
[0285] By virtue of the above-described design of the foot 16 that houses the receptacle 18, any water that accumulates in the pallet foot 16 can run out and no condensation water forms due to the air circulation. Since the receptacle 18 has no direct access to the surrounding environment, but rather is connected thereto only indirectly via the interior of the foot 16, good protection is additionally provided against water penetrating from outside.
[0286] Rectangular plan dimensions of platforms (commonly known as pallets) including but not limited to those that conform to ISO 6780:2003(E) have lengths and widths of 1200×800 mm (commonly known as Euro size), 1200×1000 mm (commonly known as full size), and 1219×1016 mm. Other standard sizes may be used in other regions of the world. The term “Half Pallet” is half of the size of the standard pallet according to the particular standard being used. Similarly, the term “Quarter Pallet” is a quarter of the size of the standard pallet according to the particular standard being used. For example, if the standard used in one region is 1200×800 mm, then a Half Pallet will have dimensions of 800×600 mm, and a Quarter Pallet will have dimensions of 600×400 mm. These standard dimensions are also applied to wheeled pallets commonly known as dollies, and also referred to as pallets on wheels or wheeled pallets. Such pallets may be manufactured from plastic, or from some other material.
