Title:
CONNECTION FITTING AND COUPLING TOOL
Document Type and Number:
WIPO Patent Application WO/2018/168162
Kind Code:
A1
Abstract:
Provided is a connection fitting that has a curved beam section having a cross-section which is circular even near a groove-shaped arm, capable of coupling another member in a pivotable manner, and capable of sufficiently ensuring the strength of the curved beam section. The connection fitting 10 is provided with: an inserting arm section 20 provided with a through hole 21 into which a connecting pin 100 is inserted; a groove-shaped arm section 30 that is provided with through holes 33a, 33b into which the connecting pin 100 is inserted, and that is positioned at one end side in the width direction facing the inserting arm section 20 positioned at the other end side; and a curved beam section 50 provided between the inserting arm section 20 and the groove-shaped arm section 30. The curved beam section 50 is provided with a circular cross-section along the entirety in the extension direction; an arcuate projection part 40, which reduces the extension length of the curved beam section 50, is provided between the curved beam section 50 and the groove-shaped arm section 30; and the thickness dimension in the thickness direction orthogonal to the width direction in a cross-section of the arcuate projection part 40 is provided so as to be greater than the diameter of the cross-section of the curved beam section 50.
