Title: Hook type shoe closure manufacture
Inventor: RUI BENOA
IPC: A43C11/14
Filed: 1995-10-23
Abstract: PROBLEM TO BE SOLVED: To obtain a simplified hook closure for a sports boot including a means elastically returning to the position pressed against the shell of the boot. SOLUTION: The Hook closure 1 is made of an elastic metallic wire, which has a shape of an open-buckle. The side branch parts 16 and 17 have different length by the value of X. Both curved end parts 18 and 19 of the branch parts are attached in the opposite side of holes, which are made into a part such as pedestal 5 whose side is fixed with another part. Since both ends of the curved end parts 18 and 19 of a lever part 3 have different length by the value of X, the pivot of lever part 3 generates a certain elastic deformation of the branch parts 16 and 17. Therefore, when the lever part 3 is fastened, both of Junction 16 and 17 return to their former positions quickly, which ensures an elastic returning function.
