Conventionally, a hose reel has been used to wind up a hose for watering (for example, Japanese Patent Application Laid-Open No. H02-201-200663 (FIG. 1) and 1-2 books

0 66638 (see Fig. 1)).

The hose reel includes a frame and a drum rotatably supported by the frame. The frame includes triangular side plates provided to face each other, and the both side plates are connected to be separated from each other. A connecting plug for connecting the faucet-side hose extends from one side of the side plate, and a handle for rotating the drum extends from the other side.

Thus, by rotating the handle, the hose can be wound around the drum and held.

However, in such a hose reel, the side plates constituting the frame are provided apart from each other, and the hose winding direction is open. As a result, the hose wound around the drum was easily distorted.

Further, the hose reel includes a frame and a drum rotatably supported by the frame, and the frame includes a left and a right side plate and a pipe material connecting the both side plates. .

Further, the drum is formed by a body on which a hose is wound, and flanges provided at both ends of the body.

However, in such a hose reel, the winding direction of the hose was open, and the hose was easily caught between the drum and the frame. Thus, in the conventional hose reel, the hose could not be wound up properly. The present invention has been made in view of such a conventional problem, and an object of the present invention is to provide a hose reel that can properly wind up a hose. Disclosure of the invention

In order to solve the above-mentioned problem, in a hose reel according to claim 1 of the present invention, a hose reel for winding a hose by rotating a drum is provided on a moving path of the hose wound on the drum. In addition, a guide portion for guiding the hose was provided, and the width dimension of the guide portion was set so as to decrease as going upward.

That is, when the drum is turned and the hose is wound, the hose may concentrate on the end of the drum. However, a guide for guiding the hose is provided on the movement path of the hose, and the width of the guide is set to be smaller as going upward.

For this reason, the hose wound around the end of the drum intensively is guided to the center side along the guide portion when a predetermined amount of the hose is laminated.

Also, in the hose reel according to claim 2 of the present invention, in the hose reel for rotating the drum and winding the hose, a guide portion for guiding the hose is provided on a moving path of the hose wound on the drum. In the guide portion, a regulating portion for preventing the hose from escaping is extended in a direction intersecting the moving direction of the wound hose, and the regulating portion is inclined toward a central portion as it goes upward. The inclined portion was set at an angle of 45 ° or more and less than 90 °.

That is, when the drum is rotated and the hose is wound, the hose may concentrate on the end of the drum. However, a guide section for guiding the hose is provided on the hose movement path, and a regulating section set on the guide section includes an inclined section inclined toward the center toward the upper side. Is set.

For this reason, the hose concentratedly wound around the end of the drum is guided toward the center by the inclined portion when a predetermined amount of the hose is stacked.

At this time, the hose contacting this inclined part has a downward component force and horizontal However, the inclination angle of the inclined portion is set to 45 degrees or more and less than 90 degrees. For this reason, the horizontal component force is equal to or more than the downward component force, and the force for guiding the hose laminated with a predetermined amount toward the center is equal to or greater than the force for pressing the hose downward.

Furthermore, in the hose reel according to claim 3 of the present invention, in the hose reel that winds the hose by rotating the drum, the hose is guided on a movement path of the hose wound around the drum. A guide portion is provided in the guide portion, and a regulating portion for preventing escape of the hose is provided in the guide portion so as to extend in a direction intersecting the moving direction of the wound hose, and a central portion of the regulating portion projects. It was formed in an arch shape.

That is, when the drum is rotated and the hose is wound, the hose may concentrate on the end of the drum. However, a guide portion for guiding the hose is provided on the hose movement path, and the regulating portion set in the guide portion is formed in an arch shape with a central portion protruding.

For this reason, the hose wound around the end of the drum in a concentrated manner is guided toward the center along the arch-shaped regulating portion when a predetermined amount of the hose is laminated.

In the hose reel according to claim 4, an opening through which the hose passes is provided in the guide portion, the regulating portion is set at an upper opening edge of the opening, and a lower opening edge of the opening is provided. Was formed linearly.

That is, when the winding of the hose around the empty drum is started, the hose to be moved is guided along the lower opening edge of the opening in the guide portion. At this time, the lower opening edge is formed in a straight line. For this reason, the hose is dispersed and wound over the entire drum.

Then, when the hose is wound around the drum by a predetermined amount, the hose is guided along the regulating portion formed by the upper opening edge of the opening in the guide portion.

Further, in the hose reel of claim 5, the drum is supported by a frame, and the guide portion is constituted by a bar provided on the frame.

This simplifies the configuration.

Also, in the hose reel according to claim 6 of the present invention, in the hose reel that winds the hose by rotating the drum, the moving path of the hose wound on the drum A guide portion having an opening through which the hose was inserted was provided thereon, and a thick portion thicker than a general portion was provided at an opening edge of the opening.

That is, the hose wound around the drum is guided to a predetermined position by passing through the opening provided in the guide portion and slidingly contacting the opening edge of the opening.

At this time, a thick portion thicker than the general portion is set at the opening edge of the opening. For this reason, the careless bending of the hose is prevented as compared with the case where the opening edge is formed to be thin.

Further, in the hose reel according to claim 7 of the present invention, in the hose reel that turns the drum and winds the hose, the opening through which the hose passes through the moving path of the hose wound around the drum. And a cross-sectional shape of an opening edge of the opening is formed in an arc shape protruding toward the center of the opening.

That is, the hose wound around the drum passes through an opening provided in the guide portion, and is guided to a predetermined position by sliding on the opening edge of the opening.

At this time, the opening edge of the opening is formed in an arc shape having a sectional shape protruding toward the center of the opening. For this reason, the contact area with the sliding hose is reduced.

In addition, in the hose reel according to claim 8, in the hose reel that winds the hose by rotating the drum, the hose reel is in contact with the hose on the movement path of the hose wound around the drum. A rotating member that rotates in a direction that encourages movement is provided. That is, the hose wound on the drum comes into contact with a rotating member provided on the movement path of the hose. At this time, the rotating member rotates in a direction in contact with the hose to promote the movement of the hose. Thereby, the hose is guided to the drum by the rotating member.

In the hose reel according to claim 8, irregularities are provided on the outer peripheral surface of the hose.

That is, when the hose is wound, the outer peripheral surface of the hose comes into sliding contact with the inner surface of the drum, the inner surface of the frame, or the like, and friction occurs. However, since the outer peripheral surface of the hose is provided with irregularities, the frictional resistance to the sliding contact point is reduced. Thereby, the winding of the hose onto the drum is performed more smoothly, and the winding is prevented from being distorted. The hose reel according to claim 10, wherein the drum having flanges on both ends of the body is rotatably supported by the frame, and the drum is accommodated in the frame. A hose entrance and exit is provided at a portion of the frame opposite to a winding position between both flanges of the drum, and the width of the entrance is changed from one flange to the other flange of the drum. It was set to the following dimensions.

That is, an inlet / outlet of the hose is provided at a portion of the frame opposite to the winding position between the two flange portions of the drum, and the hose wound around the drum moves through the inlet / outlet.

The width of the entrance is set to be equal to or less than the dimension from one flange to the other flange of the drum. For this reason, the hose accommodated in the frame via the entrance is guided between both flanges of the drum.

Further, in the hose reel of claim 11, the frame is formed in a case shape in which the drum is accommodated.

That is, the frame for rotatably supporting the drum is formed in a case shape for accommodating the drum, and a hose is provided at a portion of the frame opposite to a winding position between both flange portions of the drum. The entrance of the door is provided, and the hose wound on the drum moves through the entrance.

Furthermore, in the hose reel of claim 12, the width of the entrance is set to be smaller as going upward.

Preferably, as in claim 13, the opening の on the upper side of the entrance is formed in an arch shape with a central portion projecting upward.

That is, when the hose is wound on the drum, the hose may be concentrated on the flange side of the end of the drum and wound. However, the width of the entrance where the hose moves is set to be smaller as going upward, and preferably, the opening edge on the upper side of the entrance is formed in an arch shape with a central portion projecting upward. Have been. For this reason, the hose concentrated around the end of the drum is laminated in a predetermined amount. When this is done, it is planned to the center side along the opening edge of the doorway, preferably an arched opening edge.

In addition, in the hose reel according to claim 14, the starting point at which the opening edge is arched is set from the rotation center of the drum to the highest position of the flange portion. The hose concentratedly wound on the flange portion side of the portion is guided to the center side along the arch-shaped opening edge before reaching the highest position of the collar portion. In the hose reel of Item 15, in a hose reel in which a drum having flanges on both ends of a body is rotatably supported on a frame, a dimension between the flanges is defined as a diameter of the flange. It was set between 40% and 60% of the dimensions. That is, in the drum around which the hose is wound, the dimension between the flanges provided at both ends of the body is set to be between 40% and 60% of the diameter of the flange. When a hose is wound around the drum, even if the hose is wound around one of the flanges, it collapses inside. For this reason, the hose is guided between the two flanges by being wound around the drum.

Here, it is possible to improve the ease of winding the hose by reducing the dimension between the flanges of the drum, but if the dimension between the flanges is too small, the drum becomes thin and easily falls down. Therefore, by repeating the experiment, it was possible to achieve both by setting the dimension between the flanges of the drum between 40% and 60% of the diameter of the flange. I came to discover.

For this reason, in the present invention in which the dimension between the flanges of the drum is set to be between 40% and 60% of the diameter of the flange, the winding is performed without sacrificing the difficulty of the drum falling down. Ease of improvement is achieved. BRIEF DESCRIPTION OF THE FIGURES

You can be guided along. Thereby, the above-described effects can be obtained.

In this way, the hose 14 passing through the entrance 33 can be guided to a predetermined position by slidingly contacting the opening edge of the entrance 33. Therefore, compared to a case where the hose 14 wound around the drum 15 is not guided, it is possible to prevent the hose 14 from being distorted and to improve the appearance quality in the wound state. In addition to this, it is possible to prevent deviation of the center of gravity that may be caused by the turbulence.

At this time, a thicker portion 38 that is thicker than the general portion 37 is set in the lower regulating portion 36 that forms the opening edge of the entrance 33. For this reason, the opening edge is formed thin. In comparison with the case where the hose 14 is wound, careless bending of the hose 14 can be prevented, and the ease of winding can be improved.

Further, the thick portion 38 of the lower regulating portion 36 is formed in an arc shape having a sectional shape protruding toward the center of the entrance 33. For this reason, the contact area with the hose 14 in sliding contact can be reduced, and the frictional resistance generated during winding can be suppressed. Therefore, the winding of the hose 14 can be facilitated.

The roller 101 is rotatably supported with shaft portions 102 extending from both ends inserted into both lower ends of the eaves portion 35, and moves through the entrance 33. When it comes into contact with the hose 14 to be moved, the hose 14 is configured to rotate in a direction to promote the movement of the hose 14.

As a result, the hose 14 wound around the drum 15 comes into contact with the roller 101 provided on the movement path of the hose 14. At this time, the roller 101 comes into contact with the hose 14 and rotates in a direction to promote the movement of the hose 14. Thereby, the hose 14 can be guided to the drum 15 by the roller 101.

Therefore, as compared with the case where the hose 14 wound around the drum 15 is not guided, it is possible to prevent the hose 14 from being distorted and to wind the hose 14 properly. In addition, it is possible to improve the appearance quality in the wound state, and it is possible to prevent the bias of the center of gravity that may be caused by the turbulence.

At this time, the roller 101 rotates in a direction to promote the movement of the hose 14. Therefore, the sliding contact resistance with the hose 14 in contact with the roller 101 can be suppressed, and the winding of the hose 14 can be facilitated.

In the present embodiment, the case in which the roller 101 is provided at the lower opening edge of the entrance 33 has been described as an example. However, the present invention is not limited to this. Even if the transfer member is provided, the same effect as described above can be obtained.

In addition, it is possible to improve the appearance quality in the state where the hose is wound, and to prevent the center of gravity from being deviated due to winding disorder.

Further, in the hose reel according to the fourth aspect, when the winding of the hose on the empty drum is started, the hose to be moved can be guided along the lower opening edge of the opening in the guide portion. At this time, the lower opening 緣 is formed in a straight line. For this reason, the hose guided by the guide portion can be dispersed and wound over the entire area of the drum, and winding disturbance at the start of winding can be prevented. When the hose is wound around the drum by a predetermined amount, the guide can be guided along the restricting portion formed by the upper opening edge of the opening in the guide portion. Thereby, the same effect as described above can be obtained.
