Title:
MESHING CHAIN AND MOVABLE BODY MOVEMENT DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/031877
Kind Code:
A1
Abstract:
This meshing chain (12) comprises at least a pair of chain members (12A, 12B) capable of advancing and retreating. Each of the chain members (12A, 12B) is provided with: a plurality of link plates (22, 30) each comprising a pair of pin holes (21, 29); and a plurality of connecting pins (23). Each of the link plates (22, 30) comprises meshing surfaces (25, 32) on one end in an advance-retreat direction (Z) and engagement surfaces (27, 34) on the other end in the advance-retreat direction (Z). When chain members (12A, 12B) forming a pair mesh and are integrated, the meshing surfaces (25, 32) of the link plates (22, 30) of the chain members (12A, 12B) mesh and the engagement surfaces (27, 34) of the link plates (22, 30) engage. The engagement surfaces (27, 34) are provided with corrugated surfaces for suppressing positional displacement in the direction in which the engagement surfaces (27, 34) extend in link plates (22, 30) in which the engagement surfaces (27, 34) are engaged with each other.
