Embodiment Construction
[0071] refer to figure 1 , the chain 1 according to the invention comprises outer links 5 alternating with inner links 10, the inner links 10 and the outer links 5 being articulated to each other. Each outer link 5 includes a pair of outer plates 7 arranged parallel to each other and spaced apart so that the inner link 10 is interposed therebetween. Each inner link 10 includes a pair of inner plates 12 arranged parallel to each other and spaced apart so that the pin 15 is interposed therebetween.
[0072] The outer plates 7 are substantially flat and comprise through holes 17 at their ends.
[0073] Differently, the inner plate 12 has curved ends to form an annular rim 18, as in figure 2 The annular rim 18 is shown extending axially around the bore 19 .
[0074] Such as figure 2 As shown in , the outer link 5 and the inner link 10 pass over each other at their respective ends so that the holes 17 and 19 are aligned with each other and with the hole 20 at the center of th...
