Abstract
The invention relates to a device for winding and locking a lace comprising a fixed support, a rotatable spool, a user-operable knob for driving the spool, and elements for blocking the spool. The blocking elements comprise at least one pawl having a retaining portion engaging at least one complementary projection of the support in the absence of a rotational force exerted by the user on the knob, a base rotationally driven when the knob rotates during loosening, a first bar carrying the retaining portion and being elastically deformable, an actuating portion carried by a second bar and away from the retaining portion, the pawl being configured so that, during loosening, the knob, via the actuating portion, disengages the retaining portion.
