ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to water hoses and, more specifically, to a flat water hose having parallel water passages. The invention relates also to hose connectors adapted to connect the flat water hose to a water tap or sprinkler. The hose connectors enable a plurality of flat water hoses to be connected in a line.
2. Description of the Related Art
Conventional plastic water hoses are tubular members defining a water passage for delivering water. When a water hose is used, it is preferably fully extended out, preventing twisting. When a water hose twisted, the water passage is narrowed, reducing the output flow rate. Further, when a water hose is frequently twisted at the same area, a memory of deformation may occur. When a memory of deformation occurred, the water hose tends to be twisted at the same area. If the twisted section of the water hose is not straightened, the water hose may be permanently deformed, affecting output of water. Further, when rolling up a water hose, the hose wall must be maintained smoothly curved, keeping the water passage in a fully open status so as to prevent twisting or deformation of the hose wall. Further, when a water hose rolled up in a roll or wound round a hose reel, it still occupies much storage space.
SUMMARY OF THE INVENTION
The present invention has been accomplished under the circumstances in view. It is the main object of the present invention to provide a flat water hose, which has a reinforced wall structure that prevents twisting or deformation of the hose wall. It is another object of the present invention to provide hose connectors for flat water hose, which enables the flat water hose to be conveniently and detachably fastened to the water tap or sprinkler. According to one aspect of the present invention, the flat water hose has a flat cross section, and a plurality of water passages arranged in parallel and extended through the two distal ends. According to another aspect of the present invention, the flat water hose has two longitudinal reinforcing ribs horizontally and outwardly protruded from the periphery thereof at two opposite sides and extended between the two distal ends. According to still another aspect of the present invention, the hose connector for flat water hose comprises a mounting base member, the mounting base member having a mounting hole in one end thereof for receiving one end of the flat water hose and a receiving chamber in an opposite end thereof; a connecting member adapted to connect the mounting base member to a fitting; and a plug member adapted to secure the connecting member and the mounting base member to the flat water hose, the plug member comprising a cup-like hollow shell, the cup-like hollow shell having a close side and an open side, and a plurality of tubular plug rods respectively extended from the close side of the cup-like hollow shell in fluid communication with the inside space of the cup-like hollow shell for inserting into the water passages of the flat water hose to secure one end of the flat water hose to the inside of the mounting hole of the mounting base member.
