SHOE WITH A MECHANICAL SYSTEM OF PULLING-UP LACES Russian patent published in 2022 - IPC A43C19/00 

FIELD: footwear.

SUBSTANCE: invention relates to footwear and can be used both in civilian and military footwear samples in order to facilitate and speed up the process of putting on shoes. Shoes with a mechanical system for pulling up the laces consist of the upper, the sole, the laces, the tensioner installed with the help of guides and springs of the heel, guides, the lace tension regulator, and the blocker. The tensioner is mounted with the possibility of rotation with the help of a bearing and has a hole for fixing the end of the lace. The rotation of the tensioner is ensured by the presence of a pressure fixed on the thrust bearing, which, together with the tensioner, has parallel threads that are located on the outer surface of the pressure and inside the axial hole of the tensioner and interact when the pressure is lowered into the tensioner, causing the cord to be wound on the outer diameter of the tensioner, including inside grooves for laces. Locking the laces in the taut position is done by locking the heel in the lower position.

EFFECT: simplification of the process of putting on shoes and subsequent removal of shoes from the foot and the creation of a lace-up system capable of operating automatically using mechanical principles without the use of power supplies or hydraulics and, if necessary, having a tension control system.
