The configuration of the sprinkler 1 will be described with reference to FIG. As shown in FIG. 1, the watering tool 1 includes hoses 2A and 2B, a watering nozzle 3, a swing connector 4, and a hose reel 10. The hose 2A (main hose) is housed in the main unit 20 (described later) of the hose reel 10. A rotary connector 5A is attached to the tip of the hose 2A. The hose 2B (sub hose) is housed in the subunit 30 (described later) of the hose reel 10. A rotary connector 5B (connector) is attached to the tip of the hose 2B.

The watering nozzle 3 includes a main body 3a, a nozzle opening 3b, and a lever 3c. The tip of the main body 3a is marked with a mark indicating the type of water flow discharged from the nozzle port 3b (for example, shower, straight, mist, watering can, etc.). The nozzle port 3b is attached to the tip portion of the main body 3a so as to be rotatable with respect to the tip portion (see the arrow Ar1 in FIG. 1). The nozzle opening 3b rotates about an axis extending in the longitudinal direction of the main body 3a. In the example shown in the figure, the main body 3a and the nozzle opening 3b have a rectangular parallelepiped shape as a whole.

The watering nozzle 3 is configured to switch the type of water flow discharged from the nozzle port 3b according to the angle of the nozzle port 3b with respect to the main body 3a. For example, when the side surface of the nozzle port 3b coincides with the side surface of the main body 3a, any one of the water streams is discharged from the nozzle port 3b. The lever 3c is rotatably attached to the main body 3a. For example, the lever 3c is sprinkled with water from the nozzle port 3b when the lever 3c is pushed against the main body 3a, and the water sprinkling from the nozzle port 3b is stopped when the lever 3c is separated from the main body 3a. It may be configured in.

The rotary connector 5A is detachably and rotatably connected to the nipple 4b of the swing connector 4. The rotary connector 5B is detachably and rotatably connected to the nipple 6a attached to the faucet of the water tap 6.

[Hose reel configuration]
Subsequently, the configuration of the hose reel 10 will be described with reference to FIGS. 1 to 5. The hose reel 10 includes a main unit 20 and a subunit 30, as shown in FIGS. 1 to 3.

The main unit 20 is configured to accommodate the hose 2A. As shown in FIGS. 2 and 3, the main unit 20 includes a housing 22 (main housing), a drum 24, and a piping portion 26. The housing 22 includes side walls 22a and 22b, a bottom wall 22c, a top wall 22d, and a rear wall 22e.

The side walls 22a and 22b face each other and have a rectangular shape. The side wall 22a includes three guide pieces 22f and two locking pieces 22g (regulatory members), as shown in FIGS. 3 and 5. The side wall 22a may include at least one guide piece 22f and at least one locking piece 22g.

The guide piece 22f projects outward from the outer wall surface S of the side wall 22a. The guide piece 22f has an arc shape when viewed from the side. In the form shown in the figure, the three guide pieces 22f extend along a first virtual circle centered on the rotation axis of the drum 24.

The cross-sectional shape of the guide piece 22f is substantially L-shaped. That is, the tip of the guide piece 22f is bent so as to go outward in the radial direction about the rotation axis of the drum 24. In the form shown in the figure, the three guide pieces 22f are arranged near the corners of the front upper side, the rear upper side, and the rear lower side of the side wall 22a, respectively.

The locking piece 22g projects outward from the outer wall surface S of the side wall 22a. The locking piece 22g has an arc shape when viewed from the side. In the form shown in the figure, the two locking pieces 22g extend along a second virtual circle centered on the rotation axis of the drum 24 and radially outward from the base end portion of the guide piece 22f. .. The two locking pieces 22g are arranged apart from each other on the front lower side of the side wall 22a.

As shown in FIG. 3, the bottom wall 22c extends between them so as to connect the lower portions of the side walls 22a and 22b. As shown in FIG. 2, the front portion of the bottom wall 22c is provided with a storage portion ST configured to accommodate the watering nozzle 3 and the rotary connector 5B.

In the storage portion ST, a regulation piece STa having a shape corresponding to the outer shape of the watering nozzle 3 and the rotary connector 5B extends along the bottom wall 22c. Therefore, the watering nozzle 3 and the rotary connector 5B stored in the storage unit ST are held in the storage unit ST in a state where rattling and the like are suppressed by the regulation piece STa.

The top wall 22d extends between the upper portions of the side walls 22a and 22b so as to connect them to each other. A handle H1 is provided on the top wall 22d. The user can carry the hose reel 10 by using the handle H1. The rear wall 22e extends between the side walls 22a, 22b, the bottom wall 22c, and the top wall 22d so as to connect the rear portions thereof (see FIG. 6).

There is no wall in front of the housing 22. That is, an opening OP1 (first opening) is formed in front of the housing 22 by the front portions of the side walls 22a and 22b, the bottom wall 22c, and the top wall 22d. The opening OP1 communicates inside and outside the housing 22 so that the hose 2A and the watering nozzle 3 can enter and exit, and the tip of the hose 2B and the rotary connector 5B can enter and exit (see FIGS. 1 and 2). ).

The drum 24 has a function of winding up the hose 2A and storing it in the housing 22. As shown in FIG. 3, the drum 24 includes a cylindrical body 24a having a cylindrical shape and a pair of end face plates 24b and 24c. The tubular body 24a is rotatably attached to the side walls 22a and 22b. That is, one end of the tubular body 24a penetrates the side wall 22a, and the other end of the tubular body 24a penetrates the side wall 22b. A rotary handle (not shown) is attached to the other end of the tubular body 24a. The user can wind the hose 2A drawn from the drum 24 around the drum 24 by rotating the rotation handle in a predetermined direction.

The end face plate 24b is integrally provided on one end side of the tubular body 24a. The end face plate 24c is integrally provided on the other end side of the tubular body 24a. These end face plates 24b and 24c have a function of preventing the hose 2A from falling off from the tubular body 24a when the hose 2A is wound around the drum 24.

The piping portion 26 passes through the inside of the tubular body 24a and extends between the main unit 20 and the subunit 30. One end of the piping portion 26 is bent in an L shape, for example, and penetrates the tubular body 24a. A base end of the hose 2A is attached to one end of the piping portion 26. The other end of the piping portion 26 is bent in an L shape, for example, and is exposed in the subunit 30. The base end of the hose 2B is attached to the other end of the piping portion 26.

The subunit 30 is configured to accommodate the hose 2B. The subunit 30 includes a side ring 32 (peripheral wall) and a side cover 34 (main wall), as shown in FIGS. 2 and 3.

The side ring 32 has a cylindrical shape and extends between the outer wall surface S of the side wall 22a and the side cover 34. The side ring 32 includes an opening OP2 (second opening) and a ridge 32a (regulatory member), as shown in FIGS. 3 and 4.

The opening OP2 communicates inside and outside the subunit 30 so that the hose 2B can enter and exit (see FIGS. 1 and 2). As shown in FIG. 4, the ridge 32a projects inward from the edge of the side ring 32 on the side wall 22a side. The ridge 32a partially extends along the edge thereof and has an arc shape when viewed from the side.

The tip of the ridge 32a fits with the bent portion on the tip side of the guide piece 22f, and is located inside (closer to the rotation axis) than the locking piece 22g in the radial direction of the rotation axis of the drum 24. That is, the tip of the ridge 32a is located radially outward from the base end portion of the guide piece 22f and radially inward from the locking piece 22g with the rotation axis of the drum 24 as the center. ..

The side ring 32 is rotatably attached to the outer wall surface S of the side wall 22a by guiding the ridge 32a by the guide piece 22f. As shown in FIG. 5, when the side ring 32 rotates clockwise and the ridge 32a comes into contact with one of the locking pieces 22g, the clockwise rotation of the side ring 32 is restricted (arrow Ar3). reference). At this time, the opening OP2 of the side ring 32 faces diagonally forward and upward as shown in FIGS. 2 and 3. In the following, the position of the opening OP2 at this time will be referred to as a first position.

In a state where the bottom wall 22c is placed on a mounting surface such as the ground, the first position may be a position where the direction of the opening OP2 is 10 ° to 80 ° with respect to the horizontal plane, or 30 It may be a position of ° to 60 ° or a position of 40 ° to 50 °. In this case, when the hose 2B is wound into the subunit 30, if the opening to P2 is in the first position, the tip of the hose 2B protruding from the opening OP2 and the rotary connector 5B are obliquely upward. It will be easier to face. Therefore, it becomes easy to handle the rotary connector 5B when the rotary connector 5B is stored in the storage portion ST.

On the other hand, as shown in FIG. 7, when the side ring 32 rotates counterclockwise and the ridge 32a comes into contact with the other locking piece 22g, the rotation of the side ring 32 in the counterclockwise direction is restricted. (See arrow Ar4). At this time, the opening OP2 of the side ring 32 faces diagonally downward and rearward as shown in FIG. In the following, the position of the opening OP2 at this time will be referred to as a second position.

When the bottom wall 22c is placed on a mounting surface such as the ground, the second position may be a position where the direction of the opening OP2 is 190 ° to 260 ° with respect to the horizontal plane, or 210. It may be a position of ° to 240 ° or a position of 220 ° to 230 °. In this case, during winding of the hose 2B, as shown in FIG. 6, the tip of the hose 2B and the rotary connector 5B tend to face diagonally downward. Therefore, the accumulated water in the hose 2B is naturally discharged from the tip of the hose 2B. Therefore, it is possible to wind the hose 2B and discharge the accumulated water in the hose 2B at the same time. As a result, especially in winter, problems due to freezing of the accumulated water in the hose 2B are extremely unlikely to occur.

The side cover 34 constitutes a storage space surrounded by the side ring 32 and the outer wall surface S of the side wall 22a. The hose 2B is accommodated in the accommodation space. As shown in FIG. 3, the side cover 34 has a disk shape. A through hole 34a is provided in the central portion of the side cover 34. The through hole 34a is configured so that a protrusion 26a located on the other end side of the piping portion 26 can be inserted through the through hole 34a.

The outer surface of the side cover 34 has an uneven shape. The convex portion of the side cover 34 functions as the handle H2. When the user grips the handle H2 and rotates the side cover 34 in a predetermined direction (for example, counterclockwise), the piping portion 26 rotates at the same time, and the hose 2B is wound around the piping portion 26. When the width of the side ring 32 is set to be about the same as the diameter of the hose 2B or slightly larger than the diameter of the hose 2B, the hose 2B is accommodated in the subunit 30 in a planar spiral shape (see FIG. 2). ). In this case, the subunit 30 can be downsized.

[Action]
By the way, the hose 2B is pulled out from the inside of the subunit 30 to the outside through the opening OP2 of the side ring 32. In the above embodiment, the side ring 32 is rotatably attached to the outer wall surface S of the side wall 22a. Therefore, according to the movement of the tip end side of the hose 2B, the hose 2B is caught by the opening OP2 and pushes the side ring 32, and the side ring 32 rotates. Therefore, when the hose 2B is pulled out and the tip end side thereof is connected to the water tap 6, or when the hose 2B is wound into the subunit 30, the hose 2B naturally faces an appropriate direction. As a result, it is possible to increase the degree of freedom in handling the hose 2B and to shorten the withdrawal amount of the hose 2B. In addition, since it is extremely difficult for a load to be generated on the hose 2B in the vicinity of the opening OP2, it is possible to suppress bending of the hose 2B.

In the above embodiment, the rotatable range of the side ring 32 is limited to a predetermined range by the locking piece 22g and the ridge 32a. Therefore, due to the frictional force generated between the side ring 32 and the side cover 34, the rotation of the side ring 32 is braked by the locking piece 22g and the ridge 32a even when they rotate together. Therefore, when the side cover 34 is rotated to wind the hose 2B into the subunit 30, it is possible to suppress a situation in which the hose 2B becomes difficult to wind due to the co-rotation.

[Modification example]
Although the embodiments according to the present disclosure have been described in detail above, various modifications may be added to the above embodiments without departing from the scope of claims and the gist thereof. For example, in the above embodiment, the rotation of the side ring 32 is stopped when the ridge 32a is locked to the locking piece 22g, but the rotation range of the side ring 32 is limited. The means is not limited to this.

Specifically, the rotatable range of the side ring 32 is limited by a friction member (for example, rubber, a member including an uneven rough surface, etc.) that generates a frictional force with a part of the side ring 32. May be good. In this case, the side ring 32 rotates smoothly while the part of the side ring 32 does not come into contact with the friction member, but when the part of the side ring 32 comes into contact with the friction member, the rotation of the side ring 32 is braked. Will be done.

Alternatively, the rotatable range of the side ring 32 may be limited by an elastic member (for example, rubber, a spring, etc.) that generates a restoring force according to the amount of rotation of the side ring 32. In this case, when the amount of rotation of the side ring 32 becomes large, a restoring force of a corresponding magnitude acts on the side ring 32, so that the rotation of the side ring 32 is naturally dampened when the restoring force reaches a certain magnitude. To.

[Example]
Example 1. The hose reel according to one example of the present disclosure is configured to accommodate the main hose, and is located in the main unit including the first opening which is the outlet of the main hose and in the main unit. A drum that is rotatably attached to the main unit and is configured to wind the main hose, and a subunit that is attached to the outer wall of the main unit and is configured to accommodate the sub-hose. It extends between the inside of the main unit and the inside of the subunit via a drum, and is configured so that the base end of the main hose is connected to one end and the base end of the sub hose is connected to the other end. It is equipped with a piping section. The subunit includes a second opening that serves as an outlet for the subunit, and is configured to be rotatable independently of the main unit. In this case, the subunit is pulled out from the inside of the subunit through the second opening of the subunit. Therefore, according to the movement of the tip end side of the subunit, the subunit is caught by the second opening and pushes the subunit, and the subunit rotates. Therefore, when the sub-hose is pulled out and the tip end side thereof is connected to the faucet, or when the sub-hose is wound into the subunit, the sub-hose naturally faces an appropriate direction. As a result, it is possible to increase the degree of freedom in handling the sub-hose and to shorten the pull-out amount of the sub-hose. In addition, since it is extremely difficult for a load to be generated on the sub hose in the vicinity of the second opening, it is possible to suppress bending of the sub hose.

Example 2. In the hose reel of Example 1, the subunit includes a circular main wall and a peripheral wall extending between the main wall and the main unit and having a cylindrical shape, and a second opening is provided in the peripheral wall. The main wall may be configured to be rotatable independently of the peripheral wall.

Example 3. The hose reel of Example 1 or Example 2 may further comprise a regulatory member configured to limit the rotatable range of the subunit within the range between the first and second positions. In this case, due to the frictional force generated between the main wall and the peripheral wall, the rotation of the peripheral wall is braked by the restricting member even when the main wall and the peripheral wall rotate together. Therefore, when the main wall is rotated and the subunit is wound into the subunit, it is possible to suppress a situation in which the sub-hose becomes difficult to wind due to co-rotation.

Example 4. In the hose reel of Example 3, the restricting member is a locking piece configured to be lockable with the subunit, a friction member that generates a frictional force between the subunits, or a restoring force according to the rotation amount of the subunit. It may be an elastic member that causes

Example 5. In the hose reel of Example 3 or Example 4, the first position is that the orientation of the second opening is 10 ° to 80 ° with respect to the horizontal plane with the bottom of the main unit mounted on the mounting surface. A storage portion configured to accommodate a connector attached to the tip of a sub hose may be provided on the bottom side of the first opening. In this case, if the second opening is in the first position when the sub hose is wound up, the tip of the sub hose protruding from the second opening and the connector tend to face diagonally upward. Therefore, it becomes easy to handle the connector when storing the connector in the storage unit.

Example 6. In any of the hose reels of Examples 3 to 5, the second position is 190 ° to 260 ° to 260 ° to the horizontal plane with the bottom of the main unit mounted on the mounting surface and the orientation of the second opening to the horizontal plane. It may be a position where °. In this case, the tip of the sub hose tends to point diagonally downward while the sub hose is being wound. Therefore, the accumulated water in the sub hose is naturally discharged from the tip of the sub hose. Therefore, it is possible to wind the sub-hose and discharge the accumulated water in the sub-hose at the same time. As a result, especially in winter, problems due to freezing of the accumulated water in the sub hose are extremely unlikely to occur.
