Description

[Detailed Description of the Invention] This invention mainly relates to a scrubber in which a nonwoven fabric or a synthetic resin foam is used as a contact member.

The most important thing for scrubbing brushes with or without a handle, in which the contact member made of non-woven fabric or synthetic resin foam is fixed with a core wire, is that the contact member is completely and firmly fixed.
It should not fall off or unravel under any usage conditions, the contact parts should be simple and easy to attach, allowing for highly efficient mass production, and if non-woven fabric is used for the contact parts, the cleaning power should be low. The high cut surface becomes the rubbing surface of the scrubbing brush, the core wire is inside the wiping member, so that the core wire does not scratch the surface of the object to be cleaned during use, and the wire is in contact with the surface to be cleaned over a wide area. , The rubbing surface should preferably be formed flat, and the contact member should be cut into a rectangular or elongated shape to reduce waste of material, but the contact member fixed to the core wire should be cut into an oval or circular shape for convenient use. It lies in being formed.

Although scrubbing brushes with various structures have been developed in the past, one that fully satisfies these requirements has not yet been developed.

For example, the most basic structure, i.e., Figures 1 and 2.
As shown in the figure, both sides of the U-bent core wire 1 are sandwiched between two contact members 2 with rounded ends, and the contact surfaces are glued, thereby attaching the contact members 2 to the fixture 3. In this case, the cleaning power is weak because the surface of the nonwoven fabric is a rubbing surface instead of the cut surface, and since the sandwiching member is cut into rounds, there is a lot of waste of the contacting member.Furthermore, the contacting members are glued together and the core wire Since it is fixed to the surface, there is a drawback that it takes time and effort to attach the contact member, and if the adhesion is poor, the contact member may fall off.

This invention solves these drawbacks as well as the above-mentioned
This was developed with the aim of satisfying important requirements for scrubbers, and examples of this invention will be described below with reference to the drawings.

The scrubber with a handle shown in FIG. 3 includes a contact member 2 and a core wire 1 that connects the contact member 2 to a handle 4 that is a fixture.

The contact member 2 is made of a material that has cushioning properties and preferably water retention properties, such as a nonwoven fabric or a soft metal resin foam such as urethane foam, and as shown in FIG. It is cut to have core wire insertion holes 5 on both sides.

A wiping member 2 in the form of a long and narrow strip with insertion holes 5 formed on both sides.
As shown in FIGS. 5 and 6, both ends of the core wire 1 are inserted into the insertion hole 5, and the outer side is bent inward using the insertion hole 5 as a fold. The core wire 1 is U-bent to adhere the bent end 2a of the wiping member 2, and both ends are fixed to the handle 4.

Although not shown, if the cut surfaces on both sides of the wiping member, the upper and lower end surfaces in FIG. 4, are formed in an uneven shape, the rubbing surface of the wiping member fixed to the handle via the core wire can be formed in an uneven shape.

As shown in FIG. 5, the insertion hole 5 of the wiping member is such that when the wiping member 2 is folded at this point, the tips of the bent ends 2a do not come into contact with each other, and the thickness of the wiping member 2 is reduced. Thickness or thickness 2
It is preferable that the holes be drilled at positions approximately twice as far apart.

This is because the wiping member 2 has the insertion hole 5 at this position.
In this case, when the core wire 1 is U-bent, the newly curved ends of the wiping member 2 are not locally densely gathered together in a pressed state, and the overall density is more uniform.

In order to more completely fix the wiping member 2 to the core wire 1, as shown in FIG. As shown in FIG. 2, it is preferable to form a protrusion 6 on the wiping member contacting surface of the core wire 1, on which the wiping member is caught.

The core wire 1 can be made of wire or bendable synthetic resin.

The core wire 1 shown in FIG. 5 is molded from synthetic resin, and is formed to be somewhat thin at the bending point 1a, and the tip is formed into an arrowhead shape so that it can be inserted into the handle and fixed. There is.

This invention does not limit the structure for fixing the core wire to the fixture, and the core wire can be fitted to the fixture or welded.

The core wire is usually made as a separate member from the fixture for ease of manufacture, but if it is molded from synthetic resin, it is also possible to connect one end to the fixture and mold the two together.

In the case of a scrubber with a handle, the fixture is a handle, but in the case of a scrubber without a handle, the fixture is a hook 7 in which a hook hole 6 is formed, as shown in FIG.

As described above, in the scrubbing brush according to this invention, the wiping member is formed into an elongated band shape, both sides are bent inward, and the core wire passes through the bent portion to the outside, and this core wire is connected to the wiping member. Since the bent end of the wiping member is U-bent to the state of being tried on, and the end is connected to the fixture, the entire circumference of the wiping member is fixed in a state surrounded by the wiping member, and the wiping member is , it will not come undone or fall off under any usage conditions, and will be completely and firmly fixed, significantly extending its durability.

In particular, since the area near the base of the wiping member where it is attached to the fixing device is surrounded by the wiping member, this part, which is particularly prone to unraveling, will not unravel, and the wiping member will not lose its shape, making it convenient to use for a long time. .

In addition, since it can be manufactured by simply inserting the core wire into the wiping member and fixing it in a U-curve, it is easy to manufacture and can be mass-produced efficiently. Although it is conveniently formed into a circular or oval shape, the wiping member is cut into a rectangular shape, so there is no wastage of material.Furthermore, when a nonwoven fabric is used for the clamping member, the cut surface of the nonwoven fabric can be rubbed. Since it can be exposed on the surface, high cleaning power can be achieved, and since the rubbing surface can be formed into a superficial shape, it can contact the surface of the object to be cleaned over a wide area, resulting in a high cleaning effect.
The core wire is buried in the wiping member, and the scrubbing brush has a number of advantages that are particularly important for this type of scrubbing brush, such as preventing the core wire from scratching and damaging the object to be cleaned.
