Title:
MOTION GUIDANCE DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/009926
Kind Code:
A1
Abstract:
Provided is a motion guidance device with which it is possible to approach at least one among a rolling path or a returning part substantially tangentially, even if at least a portion of a turn part is a three-dimensional and complex 3D track. The 3D track of the at least a portion of the turn part is formed on the basis of a cross-sectional track curve (14) in the XZ cross-section of the movement guidance device, and a longitudinal track curve (15) drawn on a virtual plane VP with the longitudinal direction of the movement guidance device as the Y axis thereof, and the track length ω from the turn start point A of the cross-sectional track curve (14) as the W axis length ω thereof. The X, Z coordinates of the 3D track are the X, Z coordinates of the cross-sectional track curve (14). The Y coordinates of the 3D track are the Y coordinates of the longitudinal track curve (15) with the ω of the W axis of the virtual plane VP as a variable.
