Abstract

PROBLEM TO BE SOLVED: To prevent the spill of internal water even in case a tank part is higher than a scraping part by providing a check valve at a connecting through- hole between a scraping part and the tank part for accumulating the scraped water drops, and leading the scraped water drops to the tank part. SOLUTION: A check valve provided with a flat part 42 formed of soft, thin film-like material is interposingly inserted in a connection part between a scraping part 1 for scraping water drops stuck to a glass face, and a tank part 2 for collecting and accumulating the scraped water drops. The water drops scraped by a spatula 12 of the tip of the scraping part 1 flows down along a water collecting plate 13 and flows into the tank part 2 from a cylindrical member 15 of the connection part 3 through a flow passage 43. In case the scraping part 1 is lower than the tank part 2, water in the tank part 2 flows into the vicinity of the connection part 3 and crushes the flat part 42. The flow passage 43 is thereby blocked to prevent contraflow from the tank part 2 to the scraping part 1 side, so that water in the tank part 2 does not spill even in case of being placed retrorse in a narrow place.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, a water droplet collecting tool according to the present invention will be described in detail with reference to the drawings showing an embodiment thereof.

FIG. 1 is a perspective view of a water drop collector for explaining an embodiment of the invention of claim 1. In FIG. 1, reference numeral 1 is a scraping portion for scraping water droplets attached to the glass surface,
Reference numeral 2 denotes a tank portion that collects and collects scraped water droplets, and the scraping portion 1 and the tank portion 2 are substantially T-shaped at a connecting portion 3.
It is connected in a letter shape. As shown in FIG. 2, in the connecting portion 3, the female screw portion 11 formed on the scraping portion 1 side.
The male screw portion 21 formed on the side of the tank portion 2 is screwed into and connected to each other. The tank portion 2 is preferably made of blow-molded plastic.

A short cylindrical member 15 is provided at the base of the scraping section 1, that is, inside the female screw section 11.

As shown in FIGS. 1 and 2, the scraping portion 1
A rubber spatula 12 with a thinly molded leading edge on the tip of the
Is extended to the water collecting plate 13. Both sides and both sides of the water collecting plate 13 are covered with water collecting covers 14a and 14b, and the root sides of the water collecting plate 13 and the water collecting covers 14a and 14b are gradually thinned to match the diameter of the tank portion 2. Has been done. In addition,
The spatula 12 and the water collecting plate 13 constitute the “spa-shaped member” described in the claims.

Reference numeral 4 is a check valve inserted in the connecting portion 3, and as shown in FIG. 3, it is composed of a thick cylindrical portion 41 at the base and a slightly flat portion 42 at the tip thereof. The flat portion 42 is made of a soft film-like material, and the inside of the flat portion 42 is shown in FIG.
As shown in, the flow passage with a thin opening at the tip of the flat portion 42
43 (a structure corresponding to the "connection through hole" described in the claims) is formed.

The cylindrical portion 41 of the check valve 4 is inserted by covering the cylindrical member 15 formed on the scraping portion 1. For the flat portion 42 extending to the tubular portion 41, it is preferable to use a material molded from a thermoplastic film, a thermoplastic elastomer, or rubber. The tubular portion 41 may be made of a soft film-like material like the flat portion 42.

If the scraper 1 is used with the scraper 1 having the above-mentioned construction, the spatula 12 at the tip of the scraper 1 is moved while being pressed against the glass surface with the scrapes. It is taken and flows down along the surface of the water collecting plate 13, and reaches the flow passage 43 from the tubular member 15 of the connecting portion 3. At this time, water drops are prevented from being spilled by the water collecting covers 14a and 14b, and are guided so as to match the diameter of the connecting portion 3 and flow into the tank portion 2 through the flow passage 43.

Since the flat portion 42 extended to the tubular portion 41 is soft, when the scraping portion 1 is above the tank portion 2, the flat portion 42 hangs downward to extend and the flow passage 43 is expanded and opened. Thus, it does not prevent the water droplets scraped from flowing from the scraping portion 1 to the tank portion 2 side.

On the other hand, as shown in FIG. 4, when the scraping part 1 is located below the tank part 2 due to obstacles such as furniture, the water in the tank part 2 flows near the connecting part 3. ,
The flat portion 42 is bent and crushed by hydraulic pressure. Therefore, the flow passage 43 is closed and the scraping portion 1 is removed from the tank portion 2.
Backflow to the side can be prevented, and water in the tank portion 2 can be scraped off without spilling the water in the tank portion 2 even when facing upside down in a narrow space.

Further, as shown in FIG. 2, since the spatula 12 and the water collecting plate 13 are provided with water collecting covers 14a and 14b on both sides of the front and back sides, whichever side of the water collecting plate 13 is shown. You can scrape off the water droplets even in the upper position. As described above, since the check valve 4 described above is provided with the flat portion 42 made of a soft thin film material, even when the amount of water stored in the tank portion 2 is small, the flat portion 42 is flat when it is turned upside down. The portion 42 is crushed and the flow passage 43 is closed, and the effect of the check valve is obtained.

FIG. 5 is a plan view showing another embodiment,
In this water drop collecting tool, the connecting portion 3 ′ has a tubular member 1
It is rotatably connected about the axis of 5'and is structured to be orthogonal to the axis of rotation of the connecting part so that the spatula 12 'and the tank part 2'are not T-shaped. ing. Therefore, as shown in FIG.
When the circumference of the glass G is narrow and the work is difficult with a T-shaped water drop collecting tool, the tank 2'is parallel to the glass G with the water drop collecting tool of FIG. By doing so, the work can be done smoothly without the object A getting in the way.

Further, when there is an obstructing object B as shown in FIG. 7 and the tank portion 2'of the water drop collecting tool of FIG. 6 hits the object B and becomes an obstacle, the scraping portion 1'is left as it is. By inverting 2'from the state shown by the broken line to the state shown by the solid line, the work can be done smoothly without the object B getting in the way.

Also in the case of the water drop collector shown in FIG. 5, water collecting mechanisms may be formed by providing water collecting covers on both sides of the spatula 12 and the water collecting plate 13 as in the case of the water drop collecting device of FIG. Thereby, when there is an obstructing object B as shown in FIG. 7, not only the tank portion 2 but also the scraping portion 1 can be reversed and work can be performed. That is, the connecting portion 3 may not be rotated. Alternatively, the connecting portion 3 does not have to be rotatable.

The check valve is not limited to the structure having the flat portion 42 shown in FIG. 3, and may be a flat shape or a cylindrical shape as long as it has a soft and crushable structure.
Furthermore, it is also possible to use a disc or a sphere.

[0023]

According to the first aspect of the present invention, the connection through hole formed in the connecting portion between the scraping portion and the tank portion is provided with the check valve for preventing the backflow from the tank portion to the scraping portion. Therefore, even if it is turned upside down, the water in the tank portion does not spill, and the effect of smoothly scraping water droplets in various states can be obtained.

Further, according to the second aspect of the invention, since the connecting portion is configured to be rotatable, it is possible to freely change the direction of the spatula portion to a desired direction for scraping water droplets.

According to the invention of claim 3, since the spatula-shaped member is provided with the water collecting mechanism on both sides thereof, the scraping operation of the water droplets can be performed even when the spatula part is turned upside down. For example, since the spatula-shaped member and the longitudinal direction of the tank portion are arranged at right angles to the axial direction of the connecting through hole, the work of scraping water droplets can be performed smoothly even in a narrow place where the tank portion hits.
