发明名称 Lace Winding Device for Shoes
摘要 A lace winding device includes a base, a spool rotatably mounted in the base, a lace having two distal ends each extending through the base and each secured on the spool, a limit barrel mounted on the base, a drive member rotatably mounted in the limit barrel and connected with the spool to rotate the spool, and a ratchet block movably mounted on the limit barrel and engaging the drive member. Thus, the drive member is rotated in one direction only by limit of the ratchet block so that the spool is driven by the drive member to rotate in the positive direction only and cannot be rotated in the opposite direction so as to wind the lace easily and quickly
