Claims13
A protected 5-inch to 12-inch fitting for forming a joint for coupling fire fighting hose, the fitting having a coupling end and a hose connecting end, the fitting comprising:
- a hose clamp on the hose connecting end;
- a two-way Storz coupler with a rotating coupling collar on the coupling end, the rotating coupling collar providing an exterior surface structured to remain exposed upon coupling with another said Storz coupler;
- an inner barrel providing an inner barrel portion between the hose clamp and the two-way Storz coupler;
- and
- a bumper including protective material, the bumper:
- attached to the inner barrel portion,
- structured so as not to fully enclose the coupling end,
- having an effective outside diameter at least ¼-inch greater than the effective outside diameter of the rotating coupling collar, and
- including an inner ring and an outer ring of elastic material, the inner ring circumferentially attached to and mating with a shoulder of the inner barrel portion.
A protected 5-inch to 12-inch fitting for forming a joint for coupling fire fighting hose, the fitting having a coupling end, the fitting comprising:
- a two-way Storz coupler with a rotating coupling collar on the coupling end, the rotating coupling collar having exterior ribs structured to remain exposed upon coupling with another said Storz coupler;
- and
- a bumper including protective material, the bumper
- attached to the rotating coupling collar,
- having rib slot portions fitting between the rotating coupling collar exterior ribs,
- structured so as not to fully enclose the exterior ribs, and,
- having an effective outside diameter at least ¼-inch greater than the effective outside diameter of the rotating coupling collar.
A protected 5-inch to 12-inch fitting for forming a joint for coupling fire fighting hose, the fitting having a coupling end and hose connecting ends, the fitting comprising:
- a hose clamp on the hose connecting end;
- a two-way Storz coupler with a rotating coupling collar on the coupling end, the rotating coupling collar providing an exterior surface structured to remain exposed upon coupling with another said Storz coupler;
- and
- a bumper including protective material, the bumper
- attached to the hose clamp,
- having inner surface protrusions that mate with exterior surface cavities of the hose clamp to resist sliding motion therebetween,
- structured so as not to fully enclose the coupling end, and
- having an effective outside diameter at least ¼-inch greater than the effective outside diameter of the rotating coupling collar.
