Title:
HOSE JOINT
Document Type and Number:
WIPO Patent Application WO/2008/062654
Kind Code:
A1
Abstract:
Twisting of hose incident to clamping is perfectly prevented. A hose (H) is inserted along the outer peripheral surface (1b) of a nipple (1), a loose fitting portion (4) is rotatably fitted along the outer peripheral surface (1b) of the nipple (1), the loose fitting portion (4) and a sleeve (2) are separately fixed so as not to be movable in the axial direction, and a clamping member (3) is threaded on the outer peripheral surface of the loose fitting portion (4) so as to be movable in the axial direction toward the sleeve (2). Thus, when the clamping member (3) is drawn in the fastening direction by rotating only the loose fitting portion (4) without rotating the clamping member (3), the diameter of the sleeve (2) is reduced with no rotational force acting on it. This causes the inner peripheral surface (H1) of the hose (H) to be in contact with the outer peripheral surface (1b) of the nipple (1) with the hose (H) free from any external force due to rotational friction.
