Locking device for luggage folding wheel integral with mobile element and articulated about axis relative to base comprises traction spring stretched between fixed points on base and mobile element

摘要

The foldable wheel (1) is integral with a mobile element (2) and articulated about a rotational axis (XX') relative to a base (3). A traction spring (4) is stretched between a first fixed point (a) on the base and a second fixed point (b) on the mobile element. The spring longitudinal axis (YY') cuts the rotational axis during passage of the wheel from the folded to unfolded positions.
