DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT

[0048] FIGS. 1 and 2 show a first embodiment of a modular pallet 10 that is used to carry goods. The pallet 10 is conducted from four beams 20 and six pallet segments 30.

[0049] The beams 20 provide structural strength for the pallet 10. Each of the four beams are of the same shape with each of the beams being C-shaped steel beams. Each beam 20 has a web 21 with two depending flanges 22. Tabs 23 are located along the web 21 and can be deformed to pivot the tab 23 outwardly from the web 21. The beams 20 are spaced apart and parallel to each other. However, they are orientated differently with

[0050] The six pallet segment 30 provide the platform on which goods are carried and stored. Each pallet segment 30 is integrally formed from injection moulded polypropylene. The six pallet segments are twin walled 31 being supported by both longitudinal reinforcement members 32 and lateral reinforcement members 33. Accordingly, each pallet segment 10 is relatively hollow and accordingly relatively lightweight. The six pallet segments include two end segments 40, two tine segments 50 and two infill segments 60.

[0051] Each end pallet segment 40, as shown in more detail FIG. 3 and FIG. 4, is made up of a deck 41 and a base 42 which are interconnected by two sides 43 and two intermediate members 44. Three apertures 45 are formed within each end pallet segment 40. All of the apertures 45 are located between the deck 41 and the base 42. A C-shaped channel 46 is located within each of the sides 43 and each of the intermediate members 44 for location of respective beams 20. A front face 47 of the end pallet segment 40 is enclosed. Accordingly, the C-shaped channel 46 extends only partially through the sides 43 and the intermediate members 44.

[0052] Each tine pallet segment 50, as shown in more detail FIG. 5 and FIG. 6, is made up of a deck 51 and a base 52 which are interconnected by two sides 53 and two intermediate members 54. Three apertures 55 are formed within each tine pallet segment 50. All of the apertures 55 are located between the deck 51 and the base 52. A C-shaped channel 56 is located within each of the sides 53 and each of the intermediate members 54 for location of respective beams 20. A tine opening 58 extends between the two sides 53 and bisects the base 52.

[0053] Each infill pallet segment 60, as shown in more detail FIG. 7 and FIG. 8, is made up of a deck 61 and a base 62 which are interconnected by two sides 63 and two intermediate members 64. Three apertures 65 are formed within each infill pallet segment 60. All of the apertures 65 are located between the deck 61 and the base 62. A C-shaped channel 36 is located within each of the sides 63 and each of the intermediate members 64 for location of respective beams 20.

[0054] A brace 70, as shown in more detail FIG. 9 and FIG. 10, is located between each of the six segments 30. The brace 70 is substantially planar in shape and has slightly smaller outer dimensions than the pallets segments. The brace 70 is plastic. The brace 70 is formed from a deck 71 and a base 72 which are interconnected by two sides 73 and two intermediate members 74. Three apertures 75 are formed within each brace 70. All of the apertures 75 are located between the deck 71 and the base 72. A C-shaped channel 76 is located within each of the sides 73 and each of the intermediate members 74 for location of respective beams 20.

[0055] To construct the pallet 10, one of the end segments 40 is positioned so that the front face 47 is located adjacent the ground. The four beams 30 are then inserted into respective C-shaped channels 46 located within each of the sides 43 and each of the intermediate members 44. A brace 70 is then located over the beams 20 with the beams 20 being located through each of the sides 73 and each of the intermediate members 74. The brace 70 is both located adjacent the end segment 40 and recessed within the end segment 40.

[0056] A tine segment 50 is then located over the beams 20 with the beams 20 being located through each of the sides 53 and each of the intermediate members 54. The tine segment 50 is located adjacent the brace 70. The brace 70 is also recessed within the tine segment 50.

[0057] A further brace 70 is then located over the beams 20 with the beams 20 being located through each of the sides 73 and each of the intermediate members 74. The brace 70 is both located adjacent the tine segment 70 and recessed within the tine segment 70.

[0058] An infill segment 60 is then located over the beams 20 with the beams 20 being located through each of the sides 63 and each of the intermediate members 64. The infill segment 60 is located adjacent the brace 70. The brace 70 is also recessed within the infill segment 60.

[0059] A further brace 70 is then located over the beams 20 with the beams 20 being located through each of the sides 73 and each of the intermediate members 74. The brace 70 is located adjacent the infill segment 60 and recessed within the infill segment 60.

[0060] A further infill segment 60 is then located over the beams 20 with the beams 20 being located through each of the sides 63 and each of the intermediate members 64. The infill segment 60 is located adjacent the brace 70. The brace 70 is also recessed within the infill segment 60.

[0061] A further brace 70 is then located over the beams 20 with the beams 20 being located through each of the sides 73 and each of the intermediate members 74. The brace 70 is located adjacent the infill segment 60 and recessed within the infill segment 60.

[0062] A tine segment 50 is then located over the beams 20 with the beams 20 being located through each of the sides 53 and each of the intermediate members 54. The tine segment 50 is located adjacent the brace 70. The brace 70 is also recessed within the tine segment 50.

[0063] A further brace 70 is then located over the beams 20 with the beams 20 being located through each of the sides 73 and each of the intermediate members 74. The brace 70 is both located adjacent the tine segment 70 and recessed within the tine segment 70.

[0064] Finally, an end segment 40 is then located over the beams 20 with the beams 20 being located through each of the sides 43 and each of the intermediate members 44. The end segment 40 is located adjacent the brace 70. The brace 70 is also recessed within the end segment 50.

[0065] It should be noted that each of the segments 30 (i.e. end segments 40, tine segments 50 and infill segments 60) are located over the beams 20 whilst at a temperate that is substantially above ambient temperature. The elevated temperature of the segments 30 increases the size of the C-shaped channels 46, 56, 66. This simplifies the application of the segments 30 over the beams 20. Further, once the segments 30 cool, the size of the C-shaped channels 46, 56, 66 reduce to shrink fit the segments 30 onto the beams 20 this holding fast the segments to the beams 20.

[0066] An impact tool (not shown) is used to depress the tabs 23 along the beam 20. This is performed by locating the tool inside the apertures 45, 55, 65 of the segments 30 to a location along the beam 20 where a tab 23 is located. A force is applied to the tab 23 by the tool via a respective side 43, 53, 64 or intermediate member 44, 54, 64 which deforms the tab 23 outwardly with respect to the web 21. This located the tab 23 a respective longitudinal reinforcement member 32 to lock the beam 20 to the segment 30. This operation is performed when the segments 30 are at a temperature that is substantially above ambient temperature which either allows the segment 30 to spring back after contact with the tool, or to deform with the tab 23 further locking the tab 23 to the segment 30.

[0067] The pallet 10 provides a number of advantages. Various sized pallet segments 30 and beam 20 can be produced to cater for different sized pallets 10. However, many of the same segments 30 can be utilised by a multitude of pallets 10 allowing for reduced costs due to economies of scale. The beams 20, segments 30 and braces 70 can be made from different materials to suit specific requirements. For example, in medical environments, the beams 20, segments 30 and braces 70 can all be made of medical grade plastic.
