Abstract
A boot and a boot closure device adapted to bring two flaps of the boot close together including a control lever borne by a plate affixedly connected to one of the flaps, a rack connected to the other flap including a complementary arrangement for adjusting its position with respect to the lever. The arrangement for adjusting the rack are constituted by an adjustment zone that includes a buttonhole-shaped oblong slot obtained on the flap of the boot and demarcated by two circular end zones connected by a straight portion and whose diameter is equal to that of a locking pin affixed to the rack, and provided with a flat portion that is oriented perpendicular to the rack longitudinal displacement axis. The rack can be displaced, in view of its adjustment, from one end to the other of the buttonhole, after a rotation at 90.degree. with respect to its longitudinal axis, to allow for its free sliding in the straight portion of the buttonhole, and locked in either one of the circular end zones by a 90.degree. rotation in the opposite direction, bringing it back to a position where the flat portion of the pin is oriented perpendicular to the oblong slot.
