Document Type and Number:
WIPO Patent Application WO/2023/011661
Kind Code:
A1
Abstract:
Disclosed is a lacing device with relatively few components and simple, convenient assembly, comprising a base (1), a collar (3), a knob (6) and a winding wheel (2). The collar (3) is provided with a ratchet ring (34) which meshes with a pawl wheel (5). A concave portion is provided at the front end of the winding wheel (2), there being a gear ring (23) in the concave portion. A clutch wheel (4) is located in the concave portion, and at least one elastic engagement portion that can engage with or disengage from the gear ring (23) on the belt winding wheel (2) is provided on the clutch wheel (4). A guide rail (52) is provided on the pawl wheel (5) which retracts or releases the elastic engagement portion. The clutch wheel (4) is provided with a connector connecting to the knob (6), used for synchronously rotating the clutch wheel (4) and the knob (6). When the knob (6) rotates in one direction, the elastic engagement portion on the clutch wheel (4) meshes with the gear ring (23) on the winding wheel (2), such that the knob (6), the pawl wheel (5), the clutch wheel (4) and the winding wheel (2) synchronously rotate and stop. When the knob (6) rotates in the opposite direction, the elastic engagement portion on the clutch wheel (4) is disengaged from the gear ring (23) on the winding wheel (2), and the winding wheel freely rotates.
