DETAILED DESCRIPTION OF THE INVENTION
The starting point of the idea of the present invention is not limited to the conventional method, but is to apply the method of hand drawing, which has been most commonly used as a method of quickly dewatering a wet damp cloth, to wet umbrella dehydration. However, in the case of an umbrella, unlike a plain cloth, it is a cloth attached to an umbrella bone member, so it cannot be twisted like a hand draw, and even if it is simply squeezed by pressing, it has an umbrella bone and contains water Some effort must be made to apply the pressing force evenly throughout. Therefore, the present invention has come up with an airbag system that can be deformed following the shape of the pressed body as a means for applying a uniform pressing force to the fabric despite the presence of the umbrella bone. In the case of an air bag, the flexible membrane that makes up the bag tries to deform outwardly due to the pressure of the injected air, but if the movement is hindered by the presence of an object, that part stops moving, and only the other free parts Although it is deformed outward, it is intended to utilize the property that the pressure exerted on the outside through the flexible membrane is uniform. That is, no pressure is applied only to the portion with the umbrella bone, and the airbag can be freely deformed to apply the pressing force evenly to the fabric between the bones.
[0006]
The basic configuration is a cylindrical housing that can accommodate the portion from the tip of the stuffed umbrella to the handle, an annular airbag that is disposed in the housing and can wrap the umbrella in the center, A mechanism for supplying and discharging air to the airbag. The housing is made of a rigid material such as metal, plastic or wood. The airbag is made of water-resistant flexible material such as synthetic rubber, natural rubber, soft plastic such as vinyl, and synthetic leather. The air supply means to the airbag may be anything as long as it is a high-pressure air supply source. Generally, it is realized by connecting a blower installed outside the housing with a tubular body such as a pipe. This is done by switching the blowing direction or opening it to the atmosphere via an opening valve. The air supply means is to supply air to tighten the umbrella and squeeze the moisture when the wet umbrella is inserted into the airbag, and the means to exhaust the air is to release the umbrella after squeezing the moisture Therefore, the operation needs to be performed at the same timing, and an appropriate means for realizing this is adopted.
[0007]
The wet umbrella dewatering device of the present invention has such a basic configuration, and when the rain wet umbrella is inserted into the air bag in the housing, the blower is operated by some means, and the air to the bag is Supply is started and the bag is wrapped around the outside of the stuffed umbrella. There is a difference in the state of the cloth of the umbrella that there is a difference in the thickness depending on the amount of the cloth in the free part between the part hardened by the umbrella bone and the bone, and in the swollen state from the tip and the part from the handle, By this operation, the moisture contained in the fabric is squeezed out almost uniformly regardless of the position of the fabric, and the squeezed water flows down and drains from the lower part of the bag. After the water is squeezed, the air in the airbag is exhausted by an appropriate method so that the umbrella can be extracted. Since the pressing force on the umbrella is equally applied from the outside toward the shaft core, even if the pressing force is a little high, no strain load is generated on the umbrella, so that the moisture can be squeezed out without damaging the umbrella.
[0008]
[Example 1]
FIG. 1 shows an embodiment of the present invention. In the figure, A shows a state during normal standby, B shows a state when a wet umbrella is inserted, and C shows a state where the airbag is pressurized and moisture is squeezed. In addition, the component 1 is a plastic cylindrical housing, 2 is an annular airbag made of synthetic rubber or synthetic resin, 3 is a pipe for supply and exhaust, 4 is a blower for supply and exhaust, 5 is for exhaust It is a solenoid valve. 6 is a stand part, 7 is a water receiving tank, and 71 is a drain cock. When a wet umbrella is inserted into the apparatus in the standby state shown in A as shown in B and a switch (not shown) is turned on, the blower 4 operates to supply air to the airbag 2. When the air is supplied, the airbag 2 is inflated as shown in C and presses the wet umbrella from the outside to squeeze out moisture. The squeezed water flows down from below the bag and is stored in the water receiving tank 7. If the installation location of this device is a location where water can be allowed to flow, the cock 71 is opened and left as it is. If it is not possible to flow on the spot, connect a hose to the end of the cock, and if it is a fixed installation, pipe it so that it can be drained to an appropriate location. The air is exhausted by a settable timer (not shown) after a suitable time of air blowing, for example several seconds, and then the motor of the blower 4 is stopped and the solenoid valve 5 is opened to release pressurized air into the atmosphere. Do. In this exhaust operation, the exhaust solenoid valve 5 may not be used, and the blower 4 may be stopped by a timer and the air supply path may be switched and the air may be forcibly exhausted by inertial driving of the blower.
[0009]
[Example 2]
The example shown in FIG. 2 is a modification of the previous embodiment, in which the portion of the airbag 2 that wraps the umbrella is covered with a moisture absorbent material 8 such as a sponge having water absorption. When the airbag 2 is inflated and the wet umbrella is pressed to squeeze the moisture, the airbag presses the umbrella by intervening compression of the sponge 8 layer as shown in FIG. The squeezed water flows down the airbag as in the previous example, but when the air is exhausted and the bag contracts, the sponge 8 is uncompressed and the original shape is restored as shown in FIG. To do. At that time, the sponge 8 absorbs and retains moisture remaining on the umbrella fabric. In this embodiment, the water squeezed out by pressing of the airbag does not flow down completely below the airbag, so that the residual moisture is to be followed by the water absorption action of the sponge. The moisture absorbed and held by the sponge 8 flows down to the lower side of the airbag together with the moisture of the wet umbrella when the umbrella is pressed next time.
[0010]
[Example 3]
In the following example, as shown in FIG. 3, the airbag 2 is arranged in a plurality of divisions 21, 22, 23... In the longitudinal direction of the housing 1, that is, the vertical direction. The pipe 3 for supplying air is connected to the uppermost airbag 21, and the adjacent airbags are communicated with each other via a pressure release valve 9. The feature of this embodiment is that when the airbag 2 is inflated and the wet umbrella is pressed to squeeze the moisture, the uppermost airbag 21 is first inflated as shown in A and only the corresponding part of the umbrella is pressed. Then squeeze the water. The squeezed water flows down through the annular gap of the lower airbag. When the uppermost airbag 21 is inflated and sufficiently pressurized, the pressure release valve between the lower airbag 22 is opened and air is supplied through the upper airbag 21. Then, the airbag 22 inflates, presses the corresponding part of the umbrella to squeeze the moisture, and the squeezed water flows down through the annular gap of the lower airbag. This operation is sequentially repeated until the bottom airbag is pressurized as shown in FIG. By this operation, the moisture contained in the umbrella is sequentially squeezed out from above, so that the moisture remaining in the gap between the umbrella and the airbag is reduced and the dewatering effect is enhanced compared to the previous example where the entire umbrella is squeezed simultaneously. Can do. At the time of exhaust, it is opened to the atmosphere by an electromagnetic valve provided for each airbag.
[0011]
[Example 4]
The following example is an example in which means for sucking and draining the squeezed water is provided. As shown in FIG. 4, a water absorption nozzle 10 is disposed between two airbags positioned above and below. Each water absorption nozzle 10 is connected to a suction pump 12 via a gas-liquid separator 11 installed outside the housing 1. When the wet umbrella is inserted into the apparatus and the switch is turned on, the blower operates to start supplying air to the airbag, and the suction pump 12 also operates to start suction. In this state, the wet umbrella is sequentially pressed from the upper airbag to perform dehydration. In this process, a part of the squeezed water is sucked from the suction nozzle and flows in the process of flowing down the airbag. Accumulated in the liquid separator. Although the amount of water in the initial stage of pressing can be drained by flowing down, the air bag is further pressurized after that, and much of the water that has oozed out of the fabric does not flow down and remains. This embodiment attempts to forcibly remove the residual moisture through the suction nozzle, and is effective in removing the residual moisture.
[0012]
【The invention's effect】
The present invention is a novel type of dehydrating apparatus that presses and squeezes moisture from a wet umbrella that has been squeezed toward the axial center from the outside by an airbag, and the pressing force on the umbrella is equal from the outside toward the axial core. Therefore, even if the applied pressure is a little high, there is no strain load on the umbrella, so the umbrella can be tightly squeezed without damaging the umbrella, so it has excellent dehydration function and can achieve the necessary dehydration in a short time. It is.
[0013]
In addition, the air bag is divided into a plurality of parts in the vertical direction, and air is supplied from the upper air bag in order to press and squeeze the corresponding part of the umbrella in order, thereby squeezing the stuffed umbrella from above. Since the squeezing is performed in a grated form, the drainage of the squeezed water can be effectively performed.
[0014]
Further, the present invention employs a configuration in which a water-absorbing substance such as a sponge is coated on the surface of an airbag that comes into contact with a wet umbrella or a water-absorbing nozzle is disposed between airbags that are divided into a plurality of parts in the vertical direction. Thus, the water squeezed out by pressing the airbag can be effectively removed without remaining on the cloth.
