Metallic hose joint

A metallic hose joint, comprising:

• a hose formed from at least one of rubber and a thermosetting material;
• a nipple, with a tip end, to be inserted in said hose;
• a sleeve, with a tip end, formed concentrically with said nipple and which is used to tightly fix said hose by inserting said hose in a gap between said nipple and said sleeve wherein said gap at the tip end has a size approximately equivalent to the hose, wherein said tip end of said nipple and said tip end of the sleeve are disposed approximately adjacent to each other;
• and
• means for preventing a formation of bulges when said hose is fixedly held by said sleeve, said bulge preventing means including at least one ring-shaped caulking member formed on said sleeve, for fixedly holding said hose to said sleeve and an annular groove defined on an outer periphery of said nipple and positioned offset from being in-line with the caulking member,
• said hose having an inner wall formed so as to be received in the annular groove on said nipple when said sleeve is caulked with said hose, the groove being defined to allow a gap between a bottom portion thereof and the wall bulging therein.

A metallic hose joint comprising:

• a nipple with a tip end and a base end;
• a sleeve with a tip end and a base end formed concentrically with said nipple for retaining a thermoset hose that is inserted between a gap said nipple and said sleeve wherein said gap at the tip end has a size approximately equivalent to the hose, wherein said tip end of said nipple and said tip end of the sleeve are disposed approximately adjacent to each other;
• a caulking means integrally formed in said sleeve for fixing said hose after said hose has been inserted into said nipple and sleeve so as to prevent further movement of said hose in or out of said nipple and sleeve, and for creating a bulge in said hose;
• an external bulge preventing means for retaining said bulge within said nipple and sleeve wherein said external bulge preventing means comprises an annular groove disposed in said nipple wherein said groove and said bulge define a gap;
• and
• wherein said external bulge preventing means is disposed in said nipple so as not to be directly opposite said caulking means.
