When the outer peripheral surface of one end 24a of the rotating shaft 24 comes into contact with the inner peripheral surface of the free end 10b of the support shaft 10, stable seating is ensured by line contact. Therefore, it is formed in a circular arc shape. Thus, in the assembled state shown in FIG. 1, the rotating shaft 24 is slidably supported at both ends of the support shaft 10 without rattling.

The inner surfaces of the inner and outer flange portions 21 and 22 opposed to the disk-shaped rotating walls 21a and 22a are formed in a corrugated shape in order to ensure good support of the hose. Further, a cylindrical supporting protrusion 29 for rotatably supporting the spherical handle 28 is provided on the outer peripheral portion of the rotating wall 22a of the outer flange portion 22.

Further, as shown in FIGS. 12, 13 and 15, the water sprinkling side connector 30 inserted into the inside 24e of the rotary shaft 24 has one end 14a of the water sprinkling hose 14 at its rear end. A two-step nipple 32 is formed to cooperate with and connect with the clamping portion 31, and a male screw 33 to which the female screw of the clamping portion 31 is screwed is formed on the outer periphery on the front end side. Further, a locking flange 34 for locking the hole edge of the insertion hole 11 is integrally provided on the front end side. Further, a journal portion 35 is rotatably supported on the inner peripheral surface of the insertion hole 11 on the outer periphery of the front end side of the locking flange 34. Further, a cylindrical connecting portion 36 connected to the water supply side connector 43 is provided at a distal end protruding from the journal portion 35 to the rear side of the support wall 6 through the insertion hole 11. A fitting groove 37 into which a snap ring 41 made of a synthetic resin is fitted is formed between the connection portion 36 and the journal portion 35. The connecting portion 36 has an engaging groove 36a formed on the outer periphery thereof for the water-supply-side connector 43 to elastically engage with, and a retaining groove 36b for the seal ring 38 formed on the outer peripheral surface of the leading end. Further, on the outer peripheral edge of the locking flange 34, as shown in FIG. 11 and FIG. Four locking grooves 39 and 40 that rotate together with the locking groove 24 are formed.

As shown in FIG. 15 and FIGS. 16A and 16B, the snap ring 41 has an E-ring shape that can be expanded and deformed, and is fitted into the fitting groove 37 at an inner position of about 120 °. And one side surface 42a of the fitting projection 42 is engaged with the three projections 13 of the support wall 6 to hold the snap ring 41 on the support wall 6. It is made to let.

As shown in FIG. 15 and FIGS. 17A and 17B, the water supply side connector 43 connects the water supply hose 45 to the rear end of the cylindrical main body 44 in cooperation with the retainer 46 via female and male screws. A nipple 47 is formed integrally, and a fitting hole 44 a into which the connecting portion 36 of the water sprinkling side connector 30 is fitted is formed inside the front end side of the main body 44. On the outer peripheral portion of the main body 44, a tubular engaging / disengaging member 48 that slides in the axial direction and engages / disengages the internal locking claw 48a with the engaging groove 36a of the watering-side connector 30 is slidably provided. The engagement / disengagement member 48 is urged forward in the engagement direction by the spring force of a spring 49. In the front end opening of the main body 44, as shown in FIG. 18, three fitting grooves that fit into the tips of the three protrusions 13 of the support wall 6 to prevent the water sprinkling side connector 30 from rotating together. 50 are formed.

As shown in FIG. 15 and FIG. 19, the sprinkling hose 14 has a coil spring-shaped holding member 51 of a predetermined length inserted at a connection point with the connector 30. The holding member 51 prevents the flattening of the connection end of the watering hose 14 when the connection end with the connector 30 is bent, and has an outer diameter smaller than the inner diameter of the hose 14. As well as being formed, the distal end portion 51a on the connector 30 side is bent and formed in a folded shape, and is substantially V-shaped.

On the other hand, as shown in FIG. 15, when the distal end 51a of the holding member 51 is inserted into the vicinity of the proximal end of the nipple 32 of each connector 30, the distal end 51a is folded. A stepped annular locking wall 53 is formed integrally with the bent front edge 51b so as to be hooked in a hook shape to prevent the holding member 51 from coming off.

Therefore, according to this embodiment, a so-called cantilever type structure having only one side without supporting both ends of the winding drum 3 with the support 2 is used. Can be greatly shortened, and the whole hose winder 1 can be made compact. As a result, a large storage space is not required, and a small storage room can be sufficiently housed, and the weight can be reduced, so that the portability is improved.

Further, since the rotating shaft 24 of the winding drum 3 is supported on both ends of the supporting shaft 10 of the supporting wall 6, a stable and smooth rotation of the winding drum 3 can be obtained, and uneven wear occurs. Can be prevented. In addition, since the support shaft 10 is formed so as to be inclined so that the free end 10b rises slightly, the support shaft 10 is wound around the winding drum 3 or the winding drum 3, and water is formed inside. When the weight load of the remaining watering hose 14 is applied, it deforms substantially horizontally. Therefore, the entire outer peripheral surface 24c of the rotating shaft 24 can be constantly slid over the entire inner peripheral surface 10c of the support shaft 10, so that the winding drum 3 can always be smoothly rotated. The occurrence of uneven wear due to an uneven load during rotational sliding can be more effectively prevented. Further, since the body portion 20 is separated from the support shaft 10 by the space portion 25, the body portion 20 is crushed inward due to the tightening force of the watering hose 14 due to the squeezing force of the watering hose 14 and the swelling of the watering hose 14 during water flow. Even if deformed, the rotating shaft 24 can be stably supported at all times without affecting the supporting shaft 10.

Further, since the handle 20 is provided integrally on the outer peripheral side of the outer flange portion 22, the amount of protrusion is sufficiently small as compared with the conventional case where the handle protrudes outward from the center of the flange portion. In this respect, the overall width can be reduced in this respect, and the miniaturization can be further promoted.

Further, the handle 7 is provided only at the upper end of the support wall 6, and the grip 19 is disposed at a position substantially above the center of the winding drum 3 via the support arms 18, thereby reducing the size. Can be further promoted, and the overall weight balance when the grip portion 19 is lifted is improved, so that stable carrying becomes possible.

Also, the winding drum 3 can be attached to the support wall 6 by the water sprinkling side connector 30, and a separate member for attaching the winding drum 3 is not required. The cost can be reduced by reducing the cost.

Further, since the removal of the rotary shaft 24 from the support shaft 10 is restricted by the snap ring 41 using the water sprinkling side connector 30, the winding drum 3 is securely attached to the support wall 6 with a simple structure. This makes it possible to improve the efficiency of assembling work and achieve strong mounting.

In addition, the engagement grooves 39 and 40 of the watering-side connector 30 are engaged with the projections 26 and 27 provided on the inner surface of the tip of the rotating shaft 24, thereby restricting the free rotation of the watering-side connector 30. The integrity of the rotating shaft 24 and the water sprinkling side connector 30 can be secured.

Further, since the nozzle-side connector 15 can be hooked by the hook 16 provided at the center of one side of the frame wall 9 of the support wall 6, the watering nozzle is prevented from being dissipated and the watering hose 14 Storability is improved.

Further, since the faucet-side connector 60 can be held by the holding projections 17, 17 provided on the other side of the frame wall portion 9, the accommodation capacity of the water supply hose 45 is also improved, and the portability is improved. And the convenience is improved. In addition, since the faucet side connector 60 can be fitted and closed by the holding projections 17, 17, it is possible to prevent soil or mud from entering the opening of the faucet side connector 60, and to supply water by the mud or the like. Hose clogging can be prevented beforehand. Further, since the holding projections 17, 17 are formed so as to be separated in the mold opening direction of the support 2, the undercut portion is eliminated, and the workability of forming the support 2 is improved. Along with this, cost reductions can be achieved by reducing mold costs and resin usage. Further, the faucet side connector 60 connected to the holding projections 17, 17 can be prevented from rattling or coming off by the locking projections 17a, 17a, so that the usability is good.

Furthermore, the holding member 51 inserted into the connection point of the watering hose 14 with the connector 30 can prevent the watering hose 14 from being crushed at the time of bending. Therefore, when the holding member 51 is pulled after the insertion, the tip edge 51b is hooked inside the connector 30 like a fishhook. Achievable mounting properties. In particular, when it is caught on the locking claw 53 provided inside the connector 30, it can be more securely fixed.
