The outer peripheral edge of the tip 24d of the rotating shaft 24 has an arcuate surface shape to ensure stable seating by line contact when it comes into contact with the arcuate inner peripheral edge 10d on the bottom surface of the support shaft 10. 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.

Further, the opposed inner surfaces of the disk-shaped rotating walls 21a, 22a of the inner and outer flange portions 21, 22 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.

As shown in FIGS. 12, 13 and 15, the water sprinkling side connector 30 inserted through the inside 24e of the rotary shaft 24 has a rear end portion having one end 14a of the water sprinkling hose 14 in a cylindrical shape. A two-stage nipple 32 is formed to be connected in cooperation with the pressure 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 of the front end side. On the side, a locking flange 34 for locking the hole edge of the insertion hole 11 is integrally provided. 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 projecting 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 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 on the outer periphery thereof for elastically engaging the water supply side connector 43, and a retaining groove 36b for the seal ring 38 on the outer peripheral surface at the distal end. Further, on the outer peripheral edge of the locking flange 34, as shown in FIGS. 11 and 14, the water sprinkling side connector 30 is engaged with the respective projecting portions 26 and 27 of the rotating shaft 24 from the axial direction. Four locking grooves 39 and 40 are formed to rotate together.

As shown in FIGS. 15 and 16A and 16B, the snap ring 41 has an E-ring shape that can be expanded and contracted, and has three fittings that fit into the fitting grooves 37 at about 120 ° inside. The fitting projection 42 is provided integrally, and one side surface 42 a of the fitting projection 42 is engaged with the three projections 13 of the support wall 6 so that the snap ring 41 is held by the support wall 6. It has become.

As shown in FIGS. 15 and 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 by cooperating 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 FIGS. 15 and 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, since the so-called cantilever type structure having only one side without supporting both ends of the winding drum 3 with the support 2, the size of the winding drum 3 in the axial direction is reduced. 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 rotating action 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 inner peripheral surface 10c of the support shaft 10 can always slide on the entire outer peripheral surface 24c of the rotary shaft 24, so that the winding drum 3 can be constantly rotated smoothly and the rotary shaft can be rotated. 24, the occurrence of uneven wear due to uneven load at the time of 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, a tightening force due to a squeezing force of the watering hose 14 and a swelling of the watering hose 14 at the time of flowing water, etc. Accordingly, even when the support shaft 10 is crushed and deformed inward, the support shaft 10 is not affected, and the rotating shaft 24 can always be stably supported.

Further, since the handle 20 is integrally provided 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 is protruded 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, since 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, 18, the size is reduced. Can be further promoted, and the overall weight balance when the grip portion 19 is lifted is improved, so that stable carrying becomes possible.

Further, the winding drum 3 can be attached to the support wall 6 by the watering-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 detachment 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 engage 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.

The sprinkling hose 14 can be prevented from being crushed at the time of bending by the holding member 51 inserted into the connecting portion of the sprinkling hose 14 with the connector 30, and the tip end 51 a is formed in a folded shape. 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.

[Effect of the invention]

 As is apparent from the above description, according to the invention of claim 1, the distal end of the holding member is formed in a folded shape so that if the distal end is lightly pushed into the opening of the connector, the holding member can be bent. Since the distal end is elastically deformed inward in the closing direction, it can be inserted very easily into the connector, and the mounting workability is greatly improved. Also, when the holding member is pulled out at the predetermined insertion position, the leading edge of the leading end is firmly hooked on the inner peripheral surface of the opening of the connector in a hooked state, and is deformed in the expanding direction this time. Can be attached to prevent accidental escape.

According to the second aspect of the present invention, since the leading edge of the leading end of the holding member is locked to the locking wall, the holding member can be mounted more firmly.
