Description

[Detailed description of the invention] This invention is an improvement of a dirt remover for glass surfaces, which consists of an operating body that holds the glass in place and adsorbs it, and a wiping body that moves after the operating body and removes dirt that adheres to the glass surface. Regarding.

Move the operating body along the outside of the glass outside the tank to remove dirt that forms on the inner surface of the glass surrounding the fish tank where tropical fish are raised and admired, or safely remove dirt that adheres to the outside of the glass window of a building. It is conventionally known that an operating body is moved along the interior surface of the glass to remove dirt, and a wiping body is thereby moved together with the operating body by magnetic force to remove dirt.

In conventional wiping devices, a mat made of coarse fibers is glued to the surface of the magnetic piece of the operating body that faces the glass, and which comes into contact with the glass, and this mat scrubs away dirt that adheres to the glass surface. Because it removes dirt, it is necessary to move it back and forth over the dirt several times, which takes time.

Furthermore, after a short period of use, the mat loses its rough rigidity, and even if rubbed, the dirt will not come off, and its life will come to an end.

Therefore, the present invention solves the conventional problems by scraping the dirt off the glass surface instead of using a rough and rigid mat. explain.

A is an operating body, and B is a cleaning body, both of which are elongated boxes 1a and 1b with open fronts and a bottom and a surrounding wall, and are perfectly housed in the box for gluing and opening of the surrounding wall as shown in the figure. It has magnetic bodies 2a and 2b whose escape is prevented by a collar 1' that slightly protrudes inward from the edge.

At least one of the magnetic bodies 2a and 2b is made of a permanent magnet such as ferrite, and in this embodiment, the surface 2 of the magnetic body exposed on the open surface of the box is prevented from escaping from the box by a collar and is protected from scratches on the glass surface. In order to prevent this, it should be slightly retracted from the open surface of the box, but the method is not limited to this, and it may be the same as the open surface of the box, or it may be slightly protruded from the open surface of the box. etc. to prevent scratches on the glass surface.

In order to accommodate the magnetic material perfectly in the box where the collar 1' extends, shallow cuts are made from the open edge side along the edge of the box's surrounding wall, and between the cuts, the surrounding wall It is made to open slightly outward due to its elasticity.

A handle 3 for gripping with fingers is protrudingly provided on the outer surface of the bottom of the box of the operating body.

An example of the dimensions of each phase of the operating body and cleaning body is that the long side is approximately 5 cr for an aquarium! t, the short side is about 3 cm, and the depth is about 1.
It is a theory.

From each long side of the box of the wiping body B, right and left wings 4, 4 protrude diagonally outward in a V-shape gradually away from the side wall of the box 1b in the longitudinal section.

The leading edge 4' of each wing 4 has an acute edge shape, and is the leading edge 4' of the image.

4' is located forward of the open surface of the box 1b so that the surface 2 of the magnetic body 2b housed and fixed in the box 1b does not come into contact with the opposing surface of the glass.

The wings 4, 4 are integrally molded when the box 1b is molded from plastic.

Note that the base of the wing does not need to be located near the bottom of the box;
You can also place it a little away from the bottom, halfway up the height of the long side.

The magnetic body 2b is housed and fixed in the box 1b formed as described above, and the wiping body B is used.

Note that if a protective piece 6 such as a sponge or cloth is attached to the surface of the operating body A facing the glass, there is no risk of damaging the glass surface.

As described above, the wiping body B of the present invention has a V-shaped opening on both sides of the long side, and the tip edge has wings 44 that protrude beyond the open surface of the box and the surface of the magnetic material.

Therefore, when the operating body and the magnetic bodies of the wiping body (with the glass in between) are placed opposite each other, the magnetic body of the wiping body is attracted to the magnetic body of the operating body, causing the blades 4, 4 to bend, as shown by the chain line in FIG. The state approaches the solid line state, and the tip edge of the wing is strongly pressed against the surface of the glass to be cleaned.

Therefore, when the operating body is moved in the direction of the arrow along the glass surface, the wiping body uses the sharp blade-like parts of the tip edges 4' and 4' of both wings to scrape off the dirt from the glass surface, making it easy to operate. Moves after the body.

In this way, according to the present invention, dirt can be removed much faster and more reliably compared to the conventional rough and rigid mat that is moved back and forth many times to scrub dirt from above. Since it is a plastic acid, if the tip edge becomes worn after long use, you can easily sharpen it again by lightly filing it, allowing it to be used for a long time.

In addition, since the wiping body only needs to integrally mold the box and both wings from plastic and house the magnetic material in the molded box, the structure is simple and hard to break), and manufacturing is also extremely simple.

Furthermore, since the tip edges of both wings of the wiping body are positioned forward of the open surface of the box, the suction force acting on the magnetic material on the wiping body side can be concentrated on the tip edges of both wings, and the tip edges can be placed on the glass surface. It provides strong adhesion and can reliably remove dirt from the glass surface.

Moreover, since the contact portion with the glass surface can be reduced, the force required to move the wiping body can be reduced, and the followability of the wiping body can be improved.
