Abstract

System of synchronization of folding/unfolding of the wheels in folding structures provided with wheels; of which they consist of a foldable structure (1) provided with at least two legs (11), (13) and a carrier sub-structure (12) articulated with each other and which can be folded/unfolded between them; and wherein at least one of the legs (11), (13) has wheels (2) which, in turn, can fold/unfold relative to it. The system has means for automatic folding and unfolding of the wheels (2) when the tubular structure (1) is folded/unfolded; said means being a base part (31), a timing plate (32) and a connecting rod (34).
