In these figures, reference numeral 2 denotes a wiping portion, and reference numeral 4 denotes a grip portion. These are combined as shown in FIG. 4 as described below.

The wiping unit 2 is provided with a wiper blade 12 made of an elastic material such as a soft vinyl chloride resin.
4 attached to the front and lower edge. The converging / water-guiding section 14 has a dust-like shape as a whole.
As shown in the figure, in a planar shape, the width gradually narrows (converges) from the front edge to which the wiper blade 12 is attached to the rear end, and a tubular portion is formed at the rear end. I have. A lower backflow prevention plate 16 and an upper backflow prevention plate 16 'are formed in the tubular portion, and an elongated water hole 17 is formed between the two backflow prevention plates 16, 16'. Lower backflow prevention plate 16
Extends upward from the lower side of the tubular portion of the focusing water guide section 14 and has a height that is at least １ ／ of the height (inner diameter) of the tubular portion on which the lower backflow prevention plate is formed. Is preferred. The upper backflow prevention plate 16 ′ extends downward from the upper side of the tubular portion of the focusing water guide unit 14. The most important feature of this embodiment is that the water passage hole 17 extends in the direction of the edge of the converging water conveyance section to which the wiper blade 12 is attached (that is, in the lateral direction), and reaches the inner wall of the tubular portion on both left and right sides. It is. In addition, a locking hole 18 for hanging a tool is formed in the upper part of the focusing water guide unit 14. A first connecting portion 20 is formed at the rear end of the tubular portion for communication connection with the grip portion 4.

The inside of the grip 4 is used as a water storage tank 26. A locking hook 28 for hanging the tool is formed at the rear end of the grip 4. Further, the front end of the grip portion 4 is open, and the focusing water guiding portion 1 is opened.
4 is formed as a second connection portion 30 for communication connection with the second connection portion 4.

The converging water guide section 14 and the grip section 4 can be formed, for example, by molding polyethylene, polypropylene or hard vinyl chloride resin.

The communication connection between the first connection part 20 of the wiping part 2 and the second connection part 30 of the grip part 4 is as follows.
This is done as shown in FIG. That is, the first
Has a coaxial inner tube 22 inside,
The distal end of the second connecting portion 30 is inserted into the space of the first connecting portion 20 and the annular outer cross section of the inner tube 22. At the time of this insertion, a positional relationship in the circumferential direction is set. That is, the four mating grooves 34 formed in the inner surface of the first joint portion 20 in the circumferential direction are divided into four equal parts in the outer surface of the second joint portion 30 in the circumferential direction. 1, 3 and 5 by fitting the two mating projections 36.
Can be formed as shown in FIG.

FIG. 3 also shows a state during a wiping operation using the dew condensation wiping tool of the present embodiment. The operator grips the gripping hand 4 with the hand H, points the wiping unit 2 obliquely upward, and makes the wiper blade 12 abut against a surface W to be wiped such as a window to which dew condensation adheres. Then, the condensed water is wiped off by the wiper blade 12, flows through the focusing water guide section 14, passes through the water passage 17, and is stored in the water storage tank 26.

In this embodiment, as shown in FIG. 6, the lower backflow prevention plate 16 which can be extended upward from the lower side of the tubular portion of the focusing water supply section 14 is particularly used during the operation. Backflow from the water storage tank 26 is effectively prevented. Further, although the presence of the lower backflow prevention plate 16 and the upper backflow prevention plate 16 'hinders the flow of the wiped water to some extent, in this embodiment, the water passage holes 17 reach the left and right inner walls of the tubular portion. With this arrangement, an appropriate opening area can be obtained, and the flow of water from the focused water supply section 14 to the water storage tank 26 during operation can be achieved through the left and right inner wall portions without running water obstruction due to the presence of the backflow prevention plates 16 and 16 ′. Smooth and good.

Here, the flow (forward flow) of water from the focusing water supply section 14 to the water storage tank 26 through the water passage hole 17 is performed with the aid of gravity. Since the backflow of water from the tank 26 to the focusing and water guiding unit 14 is performed against gravity, the backflow is more effective against the backflow prevention plate 16,
The water flow resistance by 16 'is large. However, the work is not always performed in a state where the wiper blade 12 is horizontal. Rather, the work is often performed in a state in which the worker reaches out to the right and left sides and the wiper blade 12 is inclined. In this case, the fact that the left and right sides of the water passage hole 17 of this embodiment have reached the inner wall of the tubular portion works effectively. That is, in the operation in a state where the wiper blade 12 is inclined, the wiped water reaches the water storage tank 26 through the left and right inner walls of the tubular portion. Since the water reaches the inner wall, the water is guided to the water storage tank 26 very smoothly and efficiently without any water flow obstruction.

After the continuation of the work, the water stored in the water storage tank 26 is removed. This water removal can be performed by removing the wiping portion 2 from the grip portion 4 and then flowing it out of the opening of the coupling portion 30 of the grip portion 4 as shown in FIG. . Alternatively, the removal of the water stored in the water storage tank 26 is performed simply by turning the entire tool downward (that is, the grip portion 4 is positioned upward and the wiping portion 2 is positioned downward), and the water is allowed to flow down from the focusing water guiding portion 14. You can do it too. In this case, there is no need to remove the wiping unit 2 from the grip unit 4. In particular, in the present embodiment, since the water passage hole 17 has reached the inner wall of the tubular portion of the focusing water guiding section 14 as described above, the entire tool is completely tilted by tilting the inner wall reaching position downward. There is an advantage that the water in the tank can be completely removed easily without turning the tank downward.

When not using the tool of the present embodiment and not in use, the locking hole 18 or the locking hook 28 can be locked by a nail or the like and suspended. In addition, when the tool of the present embodiment is not used, as shown in FIG. 7, the circumferential arrangement of the coupling between the coupling portion 20 and the coupling portion 30 is as follows.
1, 3, and 5, the four turning projections 36 can be fitted to the four mating grooves 34 without turning the device 90 degrees. Thereby, each part of the tool can be aligned in the direction along the plane of the paper of FIG. 7 so that the tool can be in the thinnest state, which is convenient for storage. In order to facilitate the work, as shown in FIG. 5, the axis of the wiping unit 2 and the gripping unit 4 in the longitudinal direction (front-rear direction) moves downward (in FIG. 5). This is useful in the case of an embodiment that is bent.
