Title:
DEVICE FOR ADJUSTING LENGTH OF STRING
Document Type and Number:
WIPO Patent Application WO/2018/124827
Kind Code:
A1
Abstract:
Provided is a device for adjusting the length of a string. The device has an improved structure that lowers the unit cost and failure rate of a product by reducing the number of components and improves the assemblability, consistency in quality, operational stability, and convenience of future servicing of the product. In the device, a shaft and a shaft coupling part of a winding drum are simply coupled without a separate coupling member as a protruding portion formed on the shaft becomes caught in a catching portion formed on the shaft coupling part. Accordingly, coupling is enhanced, and thus replacement and maintenance of the device is easier.
