Title:
LINEAR BODY WINDING/UNWINDING MECHANISM
Document Type and Number:
WIPO Patent Application WO/2019/167645
Kind Code:
A1
Abstract:
In the present invention a central shaft, both ends of which are supported so as to enable forward/reverse rotation, two guide rings, a threaded pipe extending/retracting body, and a winding tube are arranged in the stated order concentrically and side by side in the radial direction. When the central shaft rotates, the rotation thereof is transmitted to the winding tube via the guide rings. When the central shaft rotates the threaded pipe extending/retracting body also moves reciprocally along the axial direction of the central shaft, and the winding tube moves reciprocally along the axial direction of the central shaft by means of the threaded pipe extending/retracting body, which extends and retracts. Accordingly, when the central shaft rotates, the winding tube for winding and unwinding a linear body moves along the axial direction while rotating together with the central shaft.
