Document Type and Number:
WIPO Patent Application WO/2018/143715
Kind Code:
A1
Abstract:
A string tightening device is disclosed. The string tightening device is characterized by comprising: a housing having an open upper surface; a spool which is rotatably arranged inside the housing, which has a ring-shaped planar shape, and which is configured to tighten a string when rotating in a first direction and to loosen the string when rotating in a second direction; a rotating handle arranged over the housing so as to cover the open upper surface of the housing and rotatably coupled to the housing; a rotation switching button having the shape of a column or a pin, the rotation switching button vertically penetrating the center portion of the upper surface of the rotating handle to be able to ascend and descend, the upper end portion of the rotation switching button being connected to the rotating handle to be able to rotate together with the rotating handle, and the lower end portion of rotation switching button being coupled to the spool such that, when rotating in the first direction together with the rotating handle, the spool can be rotated; an elastic spring arranged below the rotation switching button so s to pressurize the rotation switching button toward the rotating handle, the elastic spring being configured such that, when the rotation switching button receives pressure and descends, the elastic spring is contracted and, when the rotation switching button is released from the pressure, the elastic spring is restored; and a decoupling means provided inside the housing to be positioned below the rotation switching button and configured such that, when the rotation switching button descends and then ascends by means of a button pressing operation that presses the rotation switching button, the decoupling means is connected to the rotation switching button and decouples the rotation switching button and the spool from each other, and the decoupling means is spaced from the rotation switching button by a rotation starting operation that starts a rotation of the rotation switching button and enables the rotation switching button to return to the condition in which the same is coupled with the spool.
