• Figure 10 shows the variations of the assembled curved components in Figure 9, of two span components 4 and two narrow cap elements 6. There are four possible combinations possible at each joint as shown, down-down, down-up, up-down and up-up.
• Figure 11 shows sections of two span ends and two narrow cap ends of the assembly in Figure 9.
• Shaft 29 of the narrow cap end fits into hole 22 of the span end, while shaft 20 fits in hole 30, where the latch 33 engages with the bar 46 and the latch 45 engages with the bar 35 in a double locking tight fitting wedge joint.

• Two span ends connected face-to-face can then connect back-to-back to the span ends where shafts 20 fit into holes 22 and latches 33 engage with bars 35 in a tight fitting double lock wedge joint.
• a narrow cap end connects to the span end as explained in Figure 11. In this way, the assembly can connect as many span elements together as required to achieve the desired width of a toy or furniture.
• Figure 13 is a partially exploded perspective view of the assembly of a sledge.
• the table shows the quantities of the components used in the assembly.
• the width of the assembly consists of six span components and one narrow cap component.
• the span components are connected together facing each other as described in Figure 9, there is a staggered step of 18mm with the wedge shaft 20 and corresponding hole 22 exposed on either side. This allows for the span components to be connected to each other where the wedge shaft 20 locks into the corresponding hole 22.
• narrow cap elements are locked in place with the corresponding span profile components, to complete the whole assembly, with the joint assembly perpendicular to the forces of gravity, and with each joint having a double lock mechanism where the wedge shapes result in a tight fitting joint. This results in a solid assembled structure which will not come apart in use.
• Figure 14 is a plan view of a key component 50 which, when inserted into the assembled spans or cap joints, lifts the tips of the latches allowing the components to be pulled apart.
• Prongs 51, 52, 56 and 57 correspond in dimensions to notches 36 in the bars 34, 35 of the span component in Figure 6, or notches 36 in the bar 40 or 46 of the wide and narrow cap end elements in Figures 7 and 8 respectively.
• Flanges 53, 54 and 58, 59 also correspond to the dimensions of keyholes 41 and 42 in the wide cap end elements and keyholes 47 and 48 in the narrow cap end elements.
• Beams 55 and 60 correspond to the dimensions of the openings 18 and 17 in either side of the span end elements respectively.
• Figure 15 is a section showing the key component 50 inserted into slots 41 and 42 of the wide cap and span assembly, where the prongs 51 and 52 fit into the notches in bars 40 and 34 sliding under and lifting latches 32 and 39, allowing the wide cap to be easily pulled apart from the span component.
• Figure 16 is a section showing the key component 50 inserted into slots 47 and 48 of the narrow cap and span assembly, where the prongs 56 and 57 fit into the notches in bars 46 and 35 sliding under and lifting latches 33 and 45, allowing the narrow cap element to be easily pulled apart from the span component.
• Figure 17 is a section showing the key component inserted into an assembly of two span components face-to-face.
• the key is inserted inside the hollow section of shaft 20 and the hole 22 where beam 55 slides inside opening 18.
• Prongs 51 and 52 slide into the notches in bars 34 on both sides and lift the latches 32. This allows the span components to be easily separated.
• Figure 18 is a section showing the key component 50 inserted into an assembly of two span components back-to-back.
• the key is inserted inside the hollow section of shaft 19 and the hole 21 where beam 60 slides inside opening 17.
