[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an umbrella dehydrator.

[0002]

[Prior art]

 Currently, in department stores, supermarkets, halls, hospitals, office buildings, and other structures where a large number of people enter and leave, on rainy days, there are plastic bags for putting rain umbrellas at the entrance and a trash can for throwing away used bags. Currently, there are two ways to insert a wet umbrella into this plastic bag. One is to use human hands primitively, and the other is to use an automatic machine to open the mouth of the bag and insert an umbrella instead of human hands.

[0003]

[Problems to be solved by the device]

 However, each method still uses plastic bags, and every time it rains, many plastic bags are used and then discarded as garbage. This is unfavorable from the standpoint of resource saving and global environmental protection and aesthetics. The present invention eliminates such drawbacks and provides a dehydrator exclusively for umbrellas that does not use any plastic bag.

[0004]

[Means for Solving the Problems]

 The present invention has been made to solve the above problems, and includes a holder 2 that supports the boundary between an umbrella handle 1 and a mandrel, an opening control ring 3 that prevents the umbrella from opening due to centrifugal force, and an umbrella tip holding member. It is composed of a body 4, a cylindrical rotating body 5 having an open upper end, and a motor 7 for rotating the same. The holder 2 and the umbrella tip holder 4 are fixed to the upper and lower portions of the rotating body 5, respectively. The holder 2 supports the umbrella near the center axis of the rotating body 5, and the umbrella tip holding body 4 holds the umbrella at a position apart from the center axis of the rotating body 5. Designated at 4 are long umbrella tip holders 4a and 4b which also serve as the opening control ring 3.

[0005]

[Work]

 The tip of the umbrella wet with rain is inserted into the tip holder 4 through the opening control ring 3, and the base of the handle 1 is set in the notch of the holder 2 as shown in FIG. As a result, the rotor 7 and the umbrella are rotated by the motor 7, centrifugal force acts on the umbrella, and rainwater is splashed to remove water.

[0006]

【Example】

 1 to 3 show a first embodiment of the present invention, in which 1 is a handle of an umbrella, 2 is a holder having a notch for inserting a base portion of the handle 1, and a holder having a cylindrical shape with an open upper end. It is horizontally fixed to the upper end of the rolling element 5. Since the holder 2 has various thicknesses of the mandrel of the umbrella from about 6 mm to about 12 mm, the notch is narrowed toward the back as shown in Fig. 2, and the elastic material of rubber or plastic is used as the holder 2. The edge of the mandrel can be fixed by lightly pushing it in. The structure is such that this cut portion is on the center line of the rotating body 5. The rotating body 5 is supported on a turntable 6 fixed to a rotating shaft of a motor 7. The opening control ring 3 and the umbrella tip holder 4 are fixed to the upper and lower parts of the rotating body 5, respectively. The umbrella tip holder 4 has a short conical shape and has a large number of drainage holes. The holder 2 supports the umbrella near the center axis of the rotating body 5, and the umbrella tip holding body 4 holds the umbrella at a position apart from the center axis of the rotating body 5. Reference numeral 8 is a cover fixed to the main body supporting the motor 7, and 9 is a water drainer.

In the second and third embodiments shown in FIGS. 4 and 5, an example is shown in which the umbrella tip holders 4a and 4b are long so as to also serve as the opening control ring 3. In the second embodiment shown in FIG. 4, the holder 2 is fixed to a long cone-shaped umbrella tip holder 4a, and in the third embodiment shown in FIG. It is fixed to the long umbrella tip holder 4b combined with the above.

Next, the operation of this device will be described. The tip of the umbrella wet with rain is inserted into the tip holder 4 through the opening control ring 3, and the base of the handle 1 is set in the notch of the holder 2 as shown in FIG. As a result, the rotor 7 and the umbrella are rotated by the motor 7, centrifugal force acts on the umbrella, and rainwater is splashed to remove water. The scattered rainwater flows downward on the inner surface of the rotating body 5 and is discharged from the rotating table 6. At this time, when the mass of rainwater is m, the radius of rotation is r, the re-speed is ω, and the number of revolutions per minute of the motor 7 is n, the centrifugal force F = mrω ² (ω = 2πm / 60) It is more effective for the umbrella to move away from the center of rotation and to have a larger radius of rotation r, but when the radius of rotation r is increased by making the wet umbrella parallel to the center of rotation, the tip of the umbrella Is well dehydrated, but the folds of the umbrella grow larger near the handle 1 and these folds overlap and overlap in the direction opposite to the rotating direction, so to completely disperse raindrops, the dehydration time Or the rotation radius r or the rotation speed n must be increased. If the radius of gyration r is doubled, the diameter becomes four times as large, which is not preferable in terms of installation environment. Also, the number of rotations of the motor cannot be increased while ignoring the economics. In the case of the method of setting the mandrel of the umbrella on the center line of rotation as shown in Figs. 4 and 5, raindrops are more likely to be scattered at the base of the umbrella, but the radius of rotation r is smaller at the tip, and the dewatering effect is poor. For this reason, the tip portion is set at a distance of several cm from the center of rotation to increase the centrifugal force F, and the portion near the handle of the umbrella is set on the center line. In the first embodiment of FIG. 1, since the portion near the handle of the umbrella rotates around the mandrel of the umbrella, the folds of the umbrella do not overlap and raindrops are easily scattered, and the entire umbrella is dehydrated in a short time. be able to. It is preferable that the diameter of the opening control ring 3 is as large as possible because raindrops are more likely to be scattered as the folds are opened by centrifugal force.

FIG. 6 is a perspective view of a fourth embodiment of the present invention, showing an umbrella dehydrator for simultaneously dehydrating a plurality of umbrellas. In the figure, a disk-shaped holder 2a having three notches at equal intervals for supporting the boundary between the handle 1 of the umbrella and the mandrel is fixed to the upper part of the centering bar 6a of the rotating base 6, and the central rotation of the rotating base 6 is fixed. Corresponding conical umbrella tip holders 4, 4, 4 are attached to the lower part of the rod 6a by a branch rod branched from the central rolling rod 6a. 8a is a cover and 8b is its safety lid.

Since the folds on the upper part of the fabric of the umbrella are large, the folds of the umbrellas are likely to overlap with each other, making it difficult for raindrops to be scattered. Therefore, in practice, the number of umbrellas that can be set is up to three. Also, it is rare for many people to approach the entrance where it is installed at the same time. The office work time is also only temporary. Therefore, it is more practical to install several dehydrators for one umbrella.

Experimental Example Rotational speed of the rotating body 5 is 800 to 1000 times / min. Rotational output of the motor may be about 150 W. In the case of the first embodiment of FIG. 1, the dehydration time was about 15 seconds, and when snow was attached, it was about 20 seconds, and the dehydration was performed to the extent that the drop did not fall.

FIG. 7 shows an electric circuit diagram of the present invention. The motor M (7) is a power switch SW. ₁ , SW that engages with the safety lid 8b (lid that covers the entire umbrella up to the hand)₂Two parallel rainfall and snowfall timers T₁, T₂Switch SW₃, SW_Five; SW_Four, SW₆It is connected to the power supply via.

The operation of this circuit will be described. 1. Connect the power cord to AC 100V and power switch SW of the main unit₁Turn on. 2. Switch SW when the umbrella is set and the safety lid 8b is completely closed.₂Turns on. 3. The dehydration time is designed to be about 15 seconds during rainfall and about 20 seconds during snowfall. Rain switch SW₃Or snowfall switch SW_FourWhen is pressed, the rainfall timer T₁Is a snowfall timer T for 15 seconds₂Switch SW for 20 seconds_Five, SW₆Is turned on, the motor M is activated, and after the timer setting time has ended, the switch SW₃, SW _Five Or SW_Four, SW₆Is turned off and the motor M is stopped. Accidentally the rain switch SW₃And snowfall switch SW_FourIf both are pressed next, the motor M is operated until the one with the longer timer time expires, measured from the time when pressed later. In addition, the switches of the circuit whose timer time has expired are released in sequence. 4. Rainfall timer T₁Or snowfall timer T₂Power switch SW to stop the motor M while the₁, Switch SW₃, SW_FourEither of them can be turned off manually. As the dehydration method in the present invention, in addition to unidirectional rotation, a reversal method, a vibration method, or a mixture thereof can be considered.

[Correction content]

Next, the operation of this device will be described. The tip of the umbrella wet with rain is inserted into the tip holder 4 through the opening control ring 3, and the base of the handle 1 is set in the notch of the holder 2 as shown in FIG. As a result, the rotor 7 and the umbrella are rotated by the motor 7, centrifugal force acts on the umbrella, and rainwater is splashed to remove water. The scattered rainwater flows downward on the inner surface of the rotating body 5 and is discharged from the rotating table 6. In this case the mass of the rainwater m, the radius of rotation r, the angular velocity omega, the rotational speed per minute of the motor 7 is n, because it is the centrifugal force ^{F = mrω 2 (ω = 2π} n / 60), rain To disperse the droplets, it is more effective to move the umbrella farther from the center of rotation and increase the radius r of rotation. However, when the radius of rotation r is increased by making the wet umbrella parallel to the center of rotation, the tip of the umbrella The part is well dehydrated, but the folds of the umbrella grow larger near the handle 1 and these folds overlap and overlap in the direction opposite to the rotating direction, so to completely disperse raindrops, dehydration is required. Either the time must be lengthened or the radius of rotation r or the number of revolutions n must be increased. If the radius of gyration r is doubled, the diameter becomes four times as large, which is not preferable in terms of installation environment. Also, the number of rotations of the motor cannot be increased while ignoring the economics. In the case of the method of setting the mandrel of the umbrella on the center line of rotation as shown in Figs. 4 and 5, raindrops are more likely to be scattered at the base of the umbrella, but the radius of rotation r is smaller at the tip, and the dewatering effect is poor. For this reason, the tip portion is set at a distance of several cm from the center of rotation to increase the centrifugal force F, and the portion near the handle of the umbrella is set on the center line. In the first embodiment of FIG. 1, since the portion near the handle of the umbrella rotates around the mandrel of the umbrella, the folds of the umbrella do not overlap and raindrops are easily scattered, and the entire umbrella is dehydrated in a short time. be able to. It is preferable that the diameter of the opening control ring 3 is as large as possible because raindrops are more likely to be scattered as the folds are opened by centrifugal force.
