Description

Bright fine metal scrubbing tool

【Technical field】

TECHNICAL FIELD The present invention relates to a metal scrub tool for removing burns and dirt attached to pots, pots, tableware, tiles, and the like.

[Background Art]

Generally, as this kind of metal scrubbing device, a curling or coiled flat metal wire or metal fiber entangled into a handful size to form a nodular shape is often used.

This metal scrubbing device is flexible and highly abrasive, and is suitable for removing scorched and stained parts such as corners and curved surfaces of pot pots, etc. It is inconvenient to handle because it is difficult.

Conventionally, various metallic scrubbing tools have been proposed in order to solve the above disadvantages of the scrubbing tools.

One of them is a scrub part formed by winding a flat metal wire material into a coil shape and winding it into multiple layers to form a donut shape and a U-shaped cross section with a substantially inwardly open cross section. The doughnut-shaped sponge core material is wrapped from the outside with a net, and a doughnut-shaped net core body is fitted into the U-shaped groove (Japanese Utility Model Publication No. 62-28291). See).

The other is composed of an annular core made of a wire core and rubber covering the periphery of the wire core, and curling a flat metal wire material so as to surround the core material. This is a donut-shaped metal scrub tool (see Japanese Utility Model Laid-Open No. 2-15061).

By the way, in the former of the prior art, since the coiled flat metal wire comes into contact with the net and the sponge core, the net and the sponge core are used by the metal wire during use. If cut and used repeatedly, the initial shape of the scrubbing device will break down and break, resulting in poor durability. Furthermore, there is a problem that the production of the scrubbing equipment requires a lot of labor and time, and the cost is high. Also, in the latter case of the above-mentioned prior art, it is very difficult to wind a flat metal wire around an annular core material. And since the core material which put the wire core in the rubber is used, the shape retention is good, but the flexibility is poor, and when the scrubbing tool is deformed into an elliptical shape and the corners are polished, the scrubbing tool is used. However, there is a drawback in that it requires a considerable amount of force to deform the shape and is inconvenient because of poor resilience.

Furthermore, in any of the above-mentioned conventional technologies, the scrub component formed by curling or coiling the flat metal strip material collapses as the frequency of use increases, and it is complicatedly entangled to exhibit the initial function as a scrub tool. May not be possible. SUMMARY OF THE INVENTION The present invention has been made in view of the above situation, and has as its object the purpose of making a metal product which is easy to manufacture, economical, flexible, easy to use, and durable. Providing scrubbing equipment.

Another object of the present invention is to improve the shape retention of the curl or coil shape of the scrub component so that the polishing performance and flexibility as a metal scrub tool can be exhibited over a long period of time. is there.

DISCLOSURE OF THE INVENTION

In the present invention, the following technical measures have been taken to achieve the above object.

That is, the metal scrubbing device according to the present invention comprises a rod-shaped core member made of a rubber-like elastic body, and a scrub component in which a flat metal wire material is formed into a coil and a Z-shape or a coil-like shape in a plurality of layers, Both ends of the core material are connected by fixing means so that the central space has a donut shape having a size large enough to be deformed in the radial direction.

As described above, since the scrub component is wound around the rod-shaped core material and both ends of the core material are connected to form a donut shape, the work of winding the scrub component is easy and the time can be reduced. Also, since the central space of the scrubbing device is made large enough to be deformed in the radial direction, the scrubbing device can be easily deformed into an elliptical shape or the like, which is very convenient. Then, when the force applied to the scrubbing device is reduced, the original shape is easily restored.

Further, in the metal scrubbing device according to the present invention, a core material made of a rubber-like elastic body is provided with a scrub component in which a flat metal wire material is curled and Z- or coil-shaped, and wound into a plurality of layers. In the curl or coil of the scrub component, one or a plurality of metal wires or a braided cord made of elastic synthetic resin, rubber, or the like is passed through, and the cord is scrubbed. Wound around the core together with the components. Therefore, the curl or coil shape is maintained by the cord material penetrated therein, and the function as a metal scrub tool by such curl or coil shape can be exhibited for a long time. In addition, even if the curled and / or coiled scrubbing component is caught on the handle of a pot or kettle, or on the opening of a kettle while using the scrubbing device, it is still restrained by the cable. It is less likely to stretch and prevents the shape of the scrubbing equipment from breaking down, improving durability.

In the present invention, as the core material, a natural rubber, a synthetic rubber, a soft synthetic resin such as vinyl chloride, or a rubber-like elastic material selected from the group of these sponge bodies can be used. In the case of this sponge body, reduction in weight and improvement in flexibility as a scrubbing device can be expected.

The cross-sectional shape of the core material can be circular, elliptical, polygonal, etc., but by making it square, pentagonal, hexagonal, or octagonal, it prevents circumferential movement of the scrub components with respect to the core. This makes it easier to handle when using scrubbing equipment. When the cross-sectional shape of the core material is changed continuously or intermittently in the longitudinal direction, or when the cross-sectional dimension of the core material is changed continuously or intermittently in the longitudinal direction, the winding of the scrub component around the core material is performed. The device can be easily and reliably moved without shifting in the longitudinal direction of the core material, and the thickness of the scrubbing device changes, so that it is easy to remove local dirt on the object to be cleaned, such as a pot, and it is flexible. Workability such as improvement of workability and polishing is improved.

By partially increasing the number of layers of the scrub component around the core material, it becomes easier to follow curved parts such as the bottom of the pot, improving workability. Performance can be improved.

In addition, the number of layers wound around the core of the scrub component is partially increased at a plurality of locations in the longitudinal direction of the core to form bulges, and the bulges are of a plurality of sizes. Then, when polishing a corner portion such as a pot bottom, a swollen portion having the most appropriate size can be appropriately selected and can be efficiently and reliably polished. In addition, two long and short rod-shaped cores made of a flexible body, and a scrub component made of curled and Z- or coil-shaped flat gold IS filaments are individually wound into multiple layers, and the center space is reduced. Both ends of each core material are connected and integrated by fixing means so as to form a donut shape large enough to deform in the monstrous direction, forming a large and small scrub part, and a small diameter in the central space of the large diameter scrub part This scrub part is fitted, and both scrub parts are bound by one or a plurality of gold wires wound along the both cores, thereby forming an integrated metal scrub tool. In this case, it is preferable that the cross-sectional area of the outer large-diameter core is smaller than the cross-sectional area of the inner small-diameter core.

Surrounding a possible core rod 2 having a circular cross section, a scrub component 3 in which a flat metal wire (for example, a stainless steel wire) is curled and Z- or coil-shaped (including partially elongated). A plurality of layers (in this example, two layers) are wound around the core material 2 and both ends 2 A and 2 B of the core material 2 are butt-bonded to each other with an adhesive or other fixing means (for example, welding the end of the core material 2) Means, a tubular joint member, etc.) and a donut shape. The central space 4 of the donut-shaped metal scrub tool 1 has a donut shape. The core material 2 has a size sufficient to deform the core material 2 in the radial direction. Therefore, even when the core material 2 is in a donut shape, the core material 2 has good deformability and is extensible, has flexibility, and has elasticity excellent in shape retention. Deforms easily when force is applied. Therefore, the scrub component 3 can be deformed along the shape of the curved surface or the like simply by pressing the metal scrubbing tool 1 against a local portion of the object to be cleaned, for example, a curved surface at the bottom of the pot.

According to the first embodiment, the work of winding the scrub component 3 on the rod-shaped core material 2 is easy, the winding can be performed neatly, the mechanization is possible, the production is simple, and the cost can be reduced. it can. When the core material 2 is clogged with scorched dirt or dust between the linear materials constituting the scrub component 3, the fingers of both hands are inserted into the center space of the metal scrubbing device 1 and the diameter of the core material 2 is increased. By stretching in the direction, the rod-shaped core material 2 is extended, and the interval between the filaments is widened, dust and the like can be easily washed off with water, and it is easy to use and sanitary.

The flat metal wire constituting the scrub component 3 is made of a metal material such as copper or a copper alloy in addition to stainless steel, and is generally used conventionally. The scrub component 3 also has flexibility. Since it is provided, it easily deforms following the deformation of the core material 2, and the scrub component 3 itself also easily deforms. Therefore, as described above, the scrub component 3 can be easily deformed along the shape of the object to be cleaned, and the object to be cleaned can be polished thoroughly and thoroughly, and the work efficiency is improved. FIG. 5 shows a main part of the second embodiment of the present invention, in which one or a plurality of flat metal filaments are curled and Z or coil-shaped in the curl or coil of the scrub component 3. A metal wire (for example, a stainless steel wire), a cord 5 such as a braid made of rubber or elastic synthetic resin, and the like, and the cord 5 is wound around the core 2 together with the scrub component 3, The scrub component 3 is fastened to the core 2 by the cable 5, and the core 2 Are connected and integrated to form a donut-shaped metal scrub tool 1. The braided string may be a thin rubber string 5A with a plurality of thin film-shaped synthetic resin ropes 5B braided and covered (see FIG. 19). When this braided cord is used, it can be expanded and contracted, so that it is easy to wind the scrub component 3 around the core 2.

According to the second embodiment, during use of the scrubbing device 1, the flat metal wire formed into the coil and / or the coil forming the scrubbing component 3 is moved to a handle portion such as a pot or a pot. Also, even if it gets caught in the mouth of a water heater, it is restrained and restrained by the cord material 5, so that it is hardly stretched, the shape of the scrubbing device is prevented from being collapsed, and the durability is greatly improved.

The rod-shaped core material 2 shown in FIG. 6 has a quadrangular (rectangular or rectangular) cross-sectional shape, has joining notches 6 at both ends, and has corners, so that the scrub component 3 is wound around. In addition to being hard to shift in the circumferential direction, it is easy to follow a curved surface such as a pot or a corner at the corner during polishing work.

The rod-shaped core material 2 shown in FIG. 7 has a circular cross-sectional shape, and is arranged at an arbitrary interval in the longitudinal direction (a constant interval may be used) so that its cross-sectional dimension (cross-sectional area) changes intermittently in the longitudinal direction. A groove 7 is provided, a fitting protrusion 8 is provided at one end 2A, and a fitting hole 9 is provided at the other end.When the scrub component 3 is wound, it is hard to be displaced in the longitudinal direction, and during polishing work. There is no displacement of the scrub component 3 with respect to the rod-shaped core material 2 in the above, and the polishing work efficiency and the durability can be improved.

Fig. 8 shows a rod-shaped core material 2 having an octagonal cross-sectional shape, and Fig. 9 shows a rod-shaped core material 2 having a hexagonal cross-sectional shape. We can expect it.

The cutouts 10B shown in FIG. 11 are semicircular groove-shaped notches, and are provided at regular coarse intervals in the longitudinal direction. The cutouts 10C shown in FIG. 12 are cutouts having a semicircular groove shape, and are provided at a constant close interval in the longitudinal direction. The cutout 10D shown in FIG. 13 is formed in a sawtooth shape by providing V-groove-shaped notches at regular intervals.

Note that these cut portions 10A to 10D can be provided in the rod-shaped core material 2 shown in FIGS. 6, 8, 9, 14, and 15.

Fig. 14 shows the rod-shaped core material 2 in which the cross-sectional shape is rectangular and the cross-sectional dimensions are changed intermittently at predetermined intervals in the longitudinal direction (thick portions 2D and thin portions 2E are formed). Therefore, the scrub component 3 can be easily wound, and the scrub component 3 does not shift not only in the circumferential direction but also in the longitudinal direction, and the polishing efficiency is improved.

The rod-shaped core material 2 shown in Fig. 15 has a circular cross-sectional shape, and its cross-sectional dimension is continuously changed in the longitudinal direction with a constant regularity. Deviation can be prevented.

FIG. 16 shows a state before connecting both ends of the core material according to the third embodiment of the present invention, in which the scrub component 3 is wound around the outer periphery of the rod-shaped core material 2 so as to become thicker toward the center in the longitudinal direction. It is something that has been attached. As described above, when a part of the scrubbing tool 1 is made thicker, the scrubbing component 3 can easily follow the polished surface when polishing a pot or the like, so that it is easy to use and the work efficiency is improved.

FIGS. 17 and 18 show a fourth embodiment of the present invention, in which two scrub portions 11 L and 11 S of large and small diameters are combined and both scrub portions 11 L and 11 13 are combined. Binding with one or more gold wires (for example, stainless steel wire) wound along cores 2 1 ^, 2 S (for example, rubber or resin may be a stretchable synthetic resin braided string, etc.) It is one integrated.

That is, a short rod-shaped core material 2 S made of a rubber-like elastic body that can be stretched and contracted in the axial direction is wound around a plurality of layers of a scrub component 3 S in which a flat metal wire material is curled and / or coiled, Both ends of the core material 2S are connected and integrated by an adhesive or other fixing means, and the central space 4S is sufficient to deform the core material 2S and extend it in the axial direction. A donut-shaped small-diameter scrub portion 11S having a size is formed.

On the other hand, a long rod-shaped core material 2 made of the same material as the core material 2S is wound around a plurality of layers of the scrub component 3L, and both ends of the core material 2L are connected and integrated in the same manner as described above to form a central space. Small-diameter scrub 1 1 ドー Donut-shaped large-diameter scrub 1 1 L large enough to contain S ο

Then, after fitting the small-diameter scrub portion 11S into the central space of the large-diameter scrub portion 11L, the metal wire 12 is spirally formed along the axial direction of the two cores 2S and 2L. The large and small diameter scrubbing portions 11 L and 11 S are tied together and integrated to form a metal scrubbing tool 11.

The size of the cross section of the core 2 L and the scrub component 3 L of the large-diameter scrub portion 11 L is the same as the cross-section of the core 2 S and the scrub component 3 S of the small-diameter scrub 11 S. By making the cross-sectional dimension of the outer scrub part 1 IL smaller, it is easier to hold and the functionality as a scrub tool can be improved.

According to the fourth embodiment, in addition to being easy to use, it is convenient for polishing a sink or a wide surface (for example, a tile surface), so that the work efficiency can be improved. Similarly, if it is clogged with dirt or burns, it can be deformed and easily washed off with water.

In the fifth embodiment, the winding amount (number of layers) of the scrub component 3 around the core material, the half to three-quarters of the turns are substantially the same, and the other half to one-quarter of the turns are partially equal. A plurality of bulging portions having a larger winding amount are formed. In the illustrated example, five bulges are formed, of which the diameter d1 of the central bulge is the largest, the diameter d3 of the bulges at both ends is the smallest, and the bulge between them is formed. The diameter d2 of the protrusion is smaller than d1 and larger than d3.

According to the fifth embodiment, a plurality of bulging portions are appropriately selected according to the user's convenience. You can selectively polish corners such as the bottom of the pot. For example, in the case of a large pan, the radius (R) of the corner at the bottom of the pan is large, so that it can be efficiently polished by using the central bulge, and in the case of a small pan, the radius of the corner at the bottom of the pan is large. Since the rule is small, the bulges at both ends may be used.
