Claims

[Scope of Claim for Utility Model Registration] (1) In a circular tube-shaped elastic joint that fits into a pipe joint part buried underground, a joint that is provided in a ring at the center of the inner peripheral surface of the joint body made of a hard elastic material. A U-shaped groove is provided on the outer circumferential surface of the protrusion, and a high-tensile band is provided on the joint body corresponding to the waterproof packing protrudingly embedded in the inner periphery of both ends of the joint body. A flexible joint for pipe fittings. (2) A flexible joint for a pipe joint, characterized in that the high-tensile band according to claim 1 of the utility model registration is tightly fitted around the outer periphery of the joint body. (3) A flexible joint for a pipe joint, characterized in that the high-tension band described in claim 1 of the utility model registration is embedded in the joint body. (4) A flexible joint for a pipe joint, characterized in that a soft elastic body is fitted into the U-shaped groove as set forth in claim 1 of the utility model registration claim, within a range that does not reduce its effect. (5) In a circular tube-shaped elastic joint that fits into a pipe joint part buried underground, the joint body made of a hard elastic material is configured into a circular tube with a step in the width direction from approximately the center of the joint body. , a U-shaped groove is provided on the outer periphery of the stepped portion, and water stop packing is protrudingly embedded in the inner periphery of the large diameter end and the outer periphery of the small diameter end of the joint body, and the inner periphery of the large diameter end is A flexible joint for pipe fittings, characterized by having a high-tensile band on the joint body for waterproof packing. (6) A flexible joint for a pipe joint, characterized in that the high-tensile band according to claim 5 of the utility model registration is tightly fitted around the outer periphery of the joint body. (7) A flexible joint for a pipe joint, characterized in that the high-tensile band according to claim 5 of the utility model registration is embedded in the joint body.
