Abstract
Official abstract text for this publication.
A joint-ring for an endoscope-bending-tube that fits with and is fixed to a rigid-member on a distal end side, the joint-ring being formed by plastically deforming a tube-material, the joint-ring including a joint-ring-convex portion provided in the tube-material before the plastic deformation, configured to fit with distal end rigid concave portions of the distal end rigid-member to perform positioning, and protrudingly provided to the distal end side, a plastically deformed shape portion provided in the joint-ring such that an axial direction position thereof overlaps the joint-ring-convex-portion and formed by force of stretching along a circumferential surface in the plastic deformation, and joint-ring-convex-portions provided in the tube-material before the plastic deformation near both sides in the circumferential direction of the joint-ring-convex-portion to interrupt the force of stretching along the circumferential surface to keep the force from reaching the joint-ring-convex-portion to thereby prevent deformation of the joint-ring-convex-portion due to the plastic deformation.
First claim
Opening claim text (preview).
What is claimed is: 1. A joint ring for an endoscope bending tube configured to fit with and to be fixed to a rigid member on a distal end side or a proximal end side in an axial direction, the joint ring comprising: a joint ring convex portion provided in a tube material and protrudingly provided toward the distal end side or the proximal end side in the axial direction, the joint ring convex portion including side end faces that fit with a positioning shape portion provided in…
