Abstract (en)
[origin: WO2019129938A1] A device for attaching removable interchangeable heels for shoes. The invention concerns the use of a system for locking and unlocking interchangeable heels in order to change heels as desired, while keeping the same pair of shoes. The device comprises a base with tenon, called the housing (1), in which a flat locking spring (6) is located, and a mortise part (22) in which a second flat spring (24) is inserted. The mortise and tenon assembly is locked when the two flat springs (6; 24), having complementary shapes, come into contact and immobilise one another. The user can act on the tab (8) of the locking flat spring (6) in order to pivot same and unlock the heel. The flat spring (6) automatically returns to its initial position due to its elasticity, when the user releases it. The device of the invention is intended, in particular, for the production of shoes with interchangeable heels.
