Document Type and Number:
WIPO Patent Application WO/2023/234228
Kind Code:
A1
Abstract:
This gripper that can grip a soft object without damaging the same is manufactured at low cost. The present invention comprises, in an integrated manner, a pair of extension sections (10) that grip an object (2), and a connecting section (11) that connects the extension sections (10). The extension sections (10) and the connecting section (11) are configured from an elastic member having a gap section (22) that is continuous at least in the gripping direction in which the object (2) is gripped. At least a portion of the connecting section (11) is a soft region (20) having a plurality of wall sections that are layered in the gripping direction, and in the soft region (20), wall sections that neighbor one another in the gripping direction are layered in a condition of having a phase offset in an intersecting direction, which intersects the gripping direction. The extension sections (10) and the connecting section (11) comprise a configuration that results from layering, in a Z-axis direction, parallel-cross layers (24) in which linear materials (23) with elasticity have been crossed in the two directions of an X-axis direction and a Y-axis direction and assembled in a parallel-cross formation, and in the soft region (20), parallel-cross layers (24) that neighbor one another in the Z-axis direction are layered in a condition of having a phase offset in the directions of the X-axis direction and the Y-axis direction.
