Abstract ： Self-localized structures in nonlinear coupled pendulum lattices are investigated by use of the method of multiple-scales under quasi-discreteness approximation. The upper cutoff and noncutoff kinks observed by Denardo et al. recently are theoretically explained qualitatively and a lower cutoff standing soliton is also predicated.
