发明名称 Double-bow shoe lace device
摘要 A double-bow shoe lace device includes a shoe lace, two loop assemblies, and a clamp member. The shoe lace has a first lace segment forming a criss-cross pattern on eyelet tabs of a shoe, and a second lace segment that includes first and second lace portions. Each lace portion has a lower section connected to the first lace segment. Each loop assembly includes a loop segment connected to an upper section of a respective one of the lace portions, and a distal lace segment. The clamp member is sleeved slidably on the loop assemblies. Downward and upward movements of the clamp member along the loop assemblies result in tightening and loosening of the shoe.
