Title:
HOSE CLIP
Document Type and Number:
Japanese Patent JP3859255
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To make fastening force for a hose uniform along the whole periphery thereof by gradually twisting a spring plate and crossing both ends and giving second moment of area at an arbitrary point such that it satisfies a specific formula.
SOLUTION: A hose clip HC is gradually twisted along the axial direction in a bending process when it is formed and is shaped like a spiral such that both ends cross when it is twisted one turn. But, since the inner diameter of a fastening part 1 is set sufficiently large compared with its plate axis, the fastening part 1 can be uniformly put into close contact with a hose H along the whole peripheral surface thereof by changing the second moment of area such that it satisfies a specific equation IZC=IZMAX.(1+cosθ)/2 (where IZMAX is the maximum value of second moment of area at a fulcrum part of a spring plate and θ is an angle between the supporting part and an arbitrary point), which can extend the life of the hose without partially deteriorating the hose.
