DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0008] Please refer to FIG. 6 for the flat water hose connector structure of the present invention, which includes a coiler specially designed for a special flat shaped water hose. The water hose 10 is made of PVC materials with elastic property. A plurality of water passages 11, 12, 13 are disposed in parallel with each other inside the water hose 10, so that the cross-section of the water hose 10 is substantially in a flat shape. The middle of the outer sidewall of the water passages 11, 13 on both sides of the water hose 10 has a reinforced wing 14, 15 horizontally extended outward. The structural strength and supportability of the flat water hose 10 are stronger than those of the prior-art circular water hose, and will not be twisted, bent, or deformed easily.

[0009] The aforementioned coiler for flat water hose 10 comprises:

a middle partition 20 as shown in FIG. 1 and 5, is a hollow circular plastic plate for this embodiment, and has a central hole 21 in the center of the middle partition 20;

a main shaft 30 as shown in FIGs. 1, 2, and 5, substantially in the shape of circular axle, having one end extended externally to form a polygonal fixing plate 301, and the fixing plate 301at its periphery has a plurality of fixing holes 302; the main shaft 30 at the central axis has a water passage 31, and the end of the water passage 31 is close-ended, and the front end is open due to the formation of the hole, therefore a sealing up stopper 32 is tightly plugged into the front end; the main shaft 30 passes through the central hole 21 of the middle partition 20, and a blocking ring 33 is protruded outward from substantially the middle of the outer wall; a water hose connecting section 34 is protruded outward and disposed on the hose body between the blocking ring 33 and the fixing plate 301 for coupling the flat water hose 10. The water hose connecting section 34 sets the number of hollow splitters 341 depending on the number and arrangement of the water passages 11, 12, 13, and the interior of the hollow splitters 341 is connected with the water passage 31; the external open end has a protruded conical end 342; since the lengths of the hollow splitters 341 are different, the conical ends on the left and right sides are separated; the protruded conical end 342 is to increase the tightness of holding the water hose 10,and the separated conical end 342 is to prevent the protruded structure from colliding with each other and affecting the disposition of the water hose; furthermore, two outwardly protruded coupling or connecting rings 35, 36 are disposed on the hose body between the blocking ring 33 to the tail of the main shaft 30, and the wall of the shaft 30 between the two connecting rings 35, 36 has an water outlet 37; the two connecting rings 35, 36 each has a sealing up ring 351, 361;

a connecting shaft 40 as shown in FIGs. 1, 3, and 5 is disposed on the two connecting rings 35, 36 of the main shaft 30 on the side other than that of the middle partition 20; a gap exists between the inner wall of the connecting shaft 40 and the main shaft 30 with a hose body having water outlet 37, and such gap forms a water accommodating space 38; the water hose connecting section 41 is protruded from the hose body of the connecting shaft 40 for coupling the end of the flat water hose 10'; the water hose connecting section 41 sets the number of the hollow splitters 411 according to the number and arrangement of the water passages 11', 12', 13' of the water hose 10', and the interior of the hollow splitter 411 is interconnected with water accommodating space 38; the external open end has an outwardly protruded conical end 412; since the lengths of the hollow splitters 411 are different, therefore the conical ends 412 adjacent to the left and right sides are separated to prevent the protruded structure from colliding with each other and affecting the disposition of the water hose 10'; the connecting shaft 40 at its end has a polygonal fixing plate 42 extended outward, and the fixing plate 42 at its periphery has a plurality of fixing holes 421, and a blocking section 43 disposed outside the end of the main shaft 30 and tightly latched with the water blocking ring 361;

two water hose fixers 50, 50' as shown in FIGs. 1, 5 each has a water hose hole 51, 51' with a shape corresponsive to the cross-section of the water hose 10, 10' for coupling the end of the water hose 10, 10'; when the water hose 10, 10' is sheathed onto the water hose connecting section 34 of the main shaft 30 and the connecting shaft 40, the two water hose fixers 50, 50' are pressed outside the hollow splitters 341, 411 to latch the ends of the water hose 10, 10' between the hollow splitter 341, 411 and the water hose fixer 50, 50', so that the water hose 10, 10' is secured without the risk of falling apart; the bottom on each of both ends of the two water hose fixers 50, 50' has latch member 52, 52' to latch into the preset latch groove 39, 44' of the hose body of the main shaft 30 and the connecting shaft 40;

two side ring covers 65, 65' as shown in FIGs. 1 and 5 are star-shaped frame rings made of radiation decorative board, and have a polygonal groove 651, 651' in the middle for respectively latching the fixing plates 301, 42 at the ends of the main shaft and the connecting shaft and being fixed by screws 652, 652' such that the two side ring covers 65, 65' respectively link and couple to the main shaft 30 and the connecting shaft 40, and define a water accommodating space 70, 70' with the middle partition 20; a bobbin 66, 66' disposed outside the main shaft 30 and the connecting shaft 40, and the bobbin has an opening 661, 661' for passing and coupling the end of the water hose 10, 10' onto the water hose connecting section 34, 41, and a handle member 67, 67' disposed along the periphery outside the two side ring covers 65, 65' for the user to hold and turn the side ring cover 65, 65';

a main shaft balancing structure as shown in FIGs. 1, 2, and 5, has a supporting section 451 extended along an axial direction from one end of the fixing plate 301 away from the main shaft 30, and such supporting section 451 passes through the end of the connecting shaft 40 and the center of the side ring cover 65', and the other end is pivotally coupled into another side ring cover 65' such that both ends of the main shaft 30 can be supported and balanced;

two casings 60, 60' as shown in FIGs. 1 and 4 disposed on the outer side of the two side ring covers 65, 65', and its main structure is in the shape of a circular frame, and its top has a halved handle 61, 61', and its bottom has a halved footer, and the two casings are aligned and coupled to hold the middle partition 20 in between and secured by screws; the two halved handles 61, 61' constitute a handle for the user to hold, and the two halved footers 62, 62' form a stable footer; each casing 60, 60' has a water hose outlet 64, 64' for letting the open end of the two water hoses 10, 10' to pass through;

two central decorative boards 68, 68' embedded into the central exterior section of the side ring cover 65, 65' to cover and secure the screws of the main shaft 30 and the connecting shaft 40 for decoration.

[0010] By means of the aforementioned structure, when the user holds the handle member 67, 67' on either side, the side ring covers 65, 65' on the same side can be rotated, because the main shaft 30 and the connecting shaft 40 are fixed by the fixing plates 301, 42 and the side ring covers 65, 65'. Therefore the side ring covers 65, 65' respectively drive the main shaft 30 and the connecting shaft 40, and the bobbins 66, 66' also rotate accordingly to coil the water hoses 10, 10' and further store them inside the water hose accommodating space 70, 70'. The water hoses 10, 10' are neatly coiled as shown in FIG. 7, and will not be twisted, pressed, folded, or have the problem of deformation. Therefore, the water passages 11, 11', 12, 12', 13, 13' of the entire water hose are kept running smoothly. On the other hand, if the side ring covers 65, 65' are turned in the opposite direction to release the water hoses 10, 10' from the bobbins 66, 66', the user can pull the water hoses 10, 10' out to an appropriate length. Since the main shaft 30 and the connecting shaft 40 are movably coupled, therefore they can be driven by the side ring covers 65, 65' respectively and will not interfere with each other. Thus, the water hoses 10, 10' on both sides can be coiled or released independently without interfering with each other.

[0011] When the side ring cover 65 is rotated to fix the main shaft 30 into position, one end of the supporting section 451 drives two screws 454 and a washer 453 on the other side of the side ring cover 65' to turn without moving forward. Therefore, the other side ring cover 65' is not driven, but remains still.

[0012] The end of the water hose extended from the coiler can be connected to a connector 16, 17 as shown in FIGs. 6 and 7, wherein one connector can be connected to a faucet, and the other connector to a tool such as a sprinkler. The water filled from the faucet into the water passages 11, 12, 13 of the water hose 10 regardless in the extension section or the coiling section is without obstruction, therefore the water can successfully enter the water passage 31 of the main shaft 30 from the water hose connecting section 34, and fill up the water accommodating space 38 through the water outlet 37, and further into the water passages 11', 12', 13' of another water hose 10' in the water hose connecting section of the connecting shaft 40, and then is sprayed out from the sprinkler. The water in the water accommodating space 38 can be sealed by the sealing up ring 351, 361 to prevent leaking.

[0013] After disclosing the structure and application of the present invention, the inventor further describes the improvements made by the present invention below:

a.In the present invention, two water hoses are accommodated in the coiler on both sides of the water accommodating spaces 70, 70', and the coiling and releasing of water hose 10, 10' on both sides can be performed independently without interfering with each other.

b.Even the two water hoses are independent hoses, but by means of the structure arrangement of the main shaft 30 and the connecting shaft 40, their water passages 11, 11', 12, 12', 13, 13' are interconnected. The design for the coupling and movement of the main shaft 30 and the connecting shaft 40 do not affect the coiling and releasing of the two water hoses independently.

c.The water hoses 10, 10' are coiled and stored neatly into the coiler, and will not be twisted, pressed, folded, or have the problem of deformation. Therefore, the water passages 11, 11', 12, 12', 13, 13' in the entire hose regardless in the extension section or coiling section can be kept running smoothly.

d.The present invention provides a simple and easy operation by simply rotating the handle member 67, 67' to drive and rotate the side ring covers 65, 65' in order to coil or release the water hose 10, 10'. The user can also pull the water hose 10, 10' to release them for use.
