Title:
CLAMP STRUCTURE
Document Type and Number:
Japanese Patent JP3222914
Kind Code:
B2
Abstract:

PURPOSE: To provide a clamp structure that has a plastically deformable ear, so-called Oetiker's ear, by which any gaps, discontinuities or steps causing leakage are not formed on an inner clamp surface when two earlike folds are plastically formed simultaneously.
CONSTITUTION: A clamp structure 10 comprises at least one pair of plastically deformable earlike folds 15a, 15b. These folds are located on opposite sides of a central longitudinal cut of a clamping band 11, and placed in the circumferential direction by such a distance that they can be plastically deformed simultaneously using a pincherslike tool. The pincherslike tool includes two sets of jawlike members so as to permit simultaneous engagement of the two earlike folds. The pincherslike tool has fixed center members forming fixed jawlike members, and pivotally supported jawlike members operable toward one another.
