BACKGROUND OF THE INVENTION
The present invention relates to a winding device for a water supply hose used in agriculture and other fields.
[0002]
[Prior art]
A water supply hose winding device that is used at home is known as a hose drum.

Japanese Patent Application Laid-Open No. 9-172888 discloses a irrigation tube winding device that winds after squeezing with a pair of rollers.
[0006]
[Problems to be solved by the invention]
Hose drums that are widely used in home use have a configuration in which a plastics hose such as polyvinyl chloride is wound around a drum, and the hose itself is hardly deformed in terms of the cross-sectional shape during winding. If it is going to wind up, a winding diameter will become very large and handling will become inconvenient. Therefore, it is conceivable to use a flat hose that is flat in a normal state for a long hose. In the case of such a flat hose, the remaining water must be discharged. However, if the structure is simply passed through a pair of rollers, the remaining water cannot be completely discharged. The diaphragm mechanism is obstructive, making it difficult to feed out quickly, which may hinder work efficiency.
[0007]
It is an object of the present invention to clarify a hose winding device that can sufficiently perform hose throttling and that can easily perform hose feeding.
[0008]
[Means for Solving the Problems]
The hose winding device according to the present invention includes a hose winding drum arranged on a base in a state where the drum can be rotated manually, and includes a fixed roller and a movable roller. And a hose throttle mechanism having any one of the following configurations (A) or (B) , wherein the normal state of the hose is a flat hose.
(Configuration of hose throttle mechanism)
(A) The hose throttle mechanism is rotatably fixed to a fixed roller fixed to a shaft disposed substantially parallel to the base and a support member having a base end of the shaft standing on the base. And a movable roller rotatable in a direction opposite to the fixed roller.
(B) Both ends of the shaft are engaged with a fixed roller disposed at a lower position of a pair of support members erected on the base and a long hole of the support member. Is composed of a movable roller that is always urged upward by the urging means, and a footrest that is attached to the shaft of the movable roller.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
The embodiment shown in FIG. 1 will be described. The hose take-up drum 10 is pivotally supported by a bearing of a support member 21 placed on the base 20 and is prepared so as to be rotatable by operating the handle 22.
[0010]
The hose squeezing mechanism 30 is provided with a fixed roller 31 disposed on the upper surface of the base 20 and a movable roller 32 disposed in the vicinity of the fixed roller 31 and having one end of a shaft fixed rotatably. It consists of and. The movable roller 32 escapes from the path of the hose 40 in a normal state by a spring (not shown) or the like as shown in the figure. When the hose is wound, the movable roller 32 faces the fixed roller 31 in the arrow A direction. This state is maintained by pressing the shaft extension 33 on the open end side of the movable roller 32 with a foot. And roller pressure can be changed suitably by adjusting the strength of pressing by a foot. Alternatively, it is possible to employ a mode in which a stopper or the like is prepared in the shaft extension portion 33 and fixed to the fixed roller 31 side. In the case of such an aspect, by disposing a spring or the like in relation to the stopper, the state where the fixed roller 31 and the movable roller 32 are urged in the joining direction is maintained even in the normal state where the urging by the foot is released. It is possible to make it.
[0011]
The hose 40 is wound along the path indicated by the phantom line during winding. However, since the movable roller 32 is escaping during unwinding, the hose 40 can be quickly unrolled without restriction by the hose throttle mechanism. .
[0012]
A left-handed winding device can be obtained by arranging the handle 22 and the movable roller 32 on the front side in the drawing. In this case, the handle 22 is configured to be detachable, set so that the handle 22 can be arbitrarily attached to either side of the shaft of the hose winding drum 10, and the movable roller 32 can be freely replaced. It is preferable to set so as to be able to. In order to replace the movable roller 32, for example, the base end of the shaft of the movable roller 32 is fixed by a bolt and nut, and the support members 34 are prepared in two places in advance.
[0013]
Next, the embodiment shown in FIG. 2 will be described. The feature of this aspect is that the hose throttle mechanism 30 has a fixed roller 31 disposed below the pair of support members 35 disposed on the base 20, and a spring provided in the support member 35. Alternatively, the shaft of the movable roller 32 is engaged while being urged upward by a rubber band 36 or the like, and a footrest 37 is disposed on the shaft of the movable roller 32. If a foot is placed on the footrest 37 and then stepped on, the movable roller 32 descends along the long hole and comes close to the fixed roller 31, so that the hose in the path indicated by the phantom line can be narrowed down. When the foot is removed from the platform 37, the movable roller 32 returns upward by the biasing means 36 such as a spring or a rubber band. Therefore, when the hose is extended, the hose can be moved to a position where it comes into contact with the lower end of the movable roller 32 performing the upward movement operation, and a light supply can be performed. Note that tension means may be used instead of the biasing means 36.
[0014]
As in the embodiment shown in FIG. 1, it is also preferable to set the handle 22 so that it can be arbitrarily replaced on either side of the hose winding drum 10.
[0015]
The hose utilized in the present invention can be any flat hose that is normally flat. For example, “Kuraray Duct Hose Neo Alcon Neo Delicon” manufactured by Kuraray Plastics Co., Ltd. can be used.
[0016]
【The invention's effect】
According to the hose winding device of the present invention, when winding the hose, the movable roller can be made to cooperate with the fixed roller only by being stepped on with a foot or fixed with a stopper, and remains in the hose. The hose can be returned to its normal flat state and discharged while the water is being discharged, and the movable roller is escaping when the hose is extended. It is possible to carry out lightly with a route different from the route at the time of picking, and the problems mentioned above are solved.
