Abstract: PROBLEM TO BE SOLVED: To facilitate confirmation of whether or not a flexible pipe is correctly inserted.
SOLUTION: A sealant 22 includes a sealing part 60c. The sealing part 60c seals between a flexible pipe 300 and a joint body 20. The joint body 20 includes a first storage part 42, a second storage part 44, and a fluid leakage path 120. The first storage part 42 stores the sealing part 60c until the chip of the flexible pipe 300 is inserted. The second storage part 44 stores the flexible pipe 300 and the sealing part 60c when the chip of the flexible pipe 300 pushes the sealant 22 in the depth direction of the first storage part 42. The fluid leakage path 120 communicates with the outside of the joint body 20 and the second storage part 44. The part, which communicates with the second storage part 44 in the fluid leakage path 120, is formed at the part sealed with the sealing part 60c on the inner peripheral face of the second storage part 44.

Abstract: PROBLEM TO BE SOLVED: To provide a plug-in type pipe joint using a lip packing for improving sealing performance. SOLUTION: A joint body 21 stores an anti-come-off member 23, a collar 36 for holding the anti-come-off member 23, an elastic member 24 for thrusting and energizing the anti-come-off member 23 toward a tapered face 33 together with the collar 36, a spacer 38 for holding the elastic member 24 at its end, and the lip packing 25 to be closely attached to the outer peripheral face of a connection pipe 31. When water flowing in the joint body 21 flows from between the inner periphery of the joint body 21 and the terminal end of the connection pipe 31 into the lip packing 25, the lip packing 25 is subjected to water pressure to push the spacer 38 toward the upstream side in the plug-in direction of the connection pipe so that the end of a ring-shaped portion 25a on the upstream side in the plug-in direction of the connection pipe abuts on a tapered face 38t of the spacer 38. Thus, the end of the ring-shaped porion 25a on the upstream side in the plug-in direction of the connection pipe is operated to be displaced toward an inner peripheral face 39 of the joint body 21 to improve the bearing pressure on the inner peripheral face 39.

Abstract: PROBLEM TO BE SOLVED: To provide a plug-in type pipe joint for allowing easy visual check of the status of a connection pipe when being inserted, particularly, the status thereof after inserted. SOLUTION: A connection pipe plug-in clearance 8 is formed between the inner periphery of a transparent or translucent outer cylinder 3 and the outer periphery of an inner cylinder 2 for receiving one end of the connection pipe P. An insertion guide ring entry space part 15 is formed between the base end of the outer cylinder 3 and the outer periphery of the inner cylinder 2. An insertion guide ring 14 is incorporated in a joint body 1 so as to be moved toward the inner corner of the connection pipe plug-in clearance 8 as pushed by one end of the connection pipe P. A check mark M is applied onto the outer periphery of the inner cylinder 2 facing the guide ring entry space part 15. COPYRIGHT: (C)2010,JPO&INPIT

Abstract: PROBLEM TO BE SOLVED: To provide a joint for a flexible pipe capable of securely preventing a seal rubber from being pressed and deformed by a pressing ring in the half-inserted state during stock-storage etc. of the joint before insertion of the flexible pipe.
SOLUTION: The pressing ring 7 in the half-inserted state is positioned and held in an initial position in which a tip part of the pressing ring 7 is located on the rear side of the seal rubber 6 before insertion of the flexible pipe 2. A positioning and holding means is constituted by covering an exposed outer face of the pressing ring 7 in the half-inserted state with a heat-shrinkable plastic film or sheet or its tube 32 with thickness larger than a clearance c between the inner peripheral face of a port part 3 and the outer peripheral face of the pressing ring 7 so that the front end part 32a of the plastic film or sheet or its tube 32 is made to abut on an inlet side end face 3a of the port part 3 and heating and shrinking the plastic film or sheet or its tube 32 to surround the exposed outer face. After insertion of the flexible pipe 2, the plastic film or sheet or its tube 32 is removed so that the pressing ring 7 is pressed by the pressing margin.
