Multi-tube sprinkler hose |
摘要 |
This invention is directed toward the field of hoses, more particularly hoses for the even delivery and distribution of pressurized water, and most particularly a flexible plastic sprinkler hose (5) having three contiguous tubes with two perforated outer tubes (12 and 14) for spraying water outwardly to the surrounding areas to be watered, and a closed-end imperforate central tube (15) for maximizing water volume and flow in the two perforated tubes (12 and 14). The closed-end imperforate central tube (15) also equalizes water pressure along the length of the hose to cause the hose (5) to lie flat and extended when in use. |
