The present invention relates to a surface treatment device formed by assembling components of a simple structure. The surface treatment device can be used as a polishing agent coating device for polishing the body of a motor vehicle, tires, furniture, etc. , It can also be used as a cleaning device, an erasing tool for blackboards, etc.

Background technique

In the past, many brushes and coating devices provided with a handle to be held by an operator have been proposed.

As a brush having a treatment part composed of a plurality of bristles, typically a toothbrush, a suit brush, etc., the treatment part is often small in area, or the treatment plane is generally rod-shaped. Generally, the base ends of the plurality of bristles are collectively bonded and fixed to the stand by an adhesive.

For the coating device, various materials for forming the treatment part have been proposed. For example, as a treatment part of the type that can store a liquid composition inside, it is composed of a continuous porous elastic body such as a sponge, or the surface is covered with cloth, etc., or it is felt. etc. In many cases, the area of the processing part is large. For example, when the processing part is made of a sponge, etc., the back surface of the pedestal is bonded and fixed on the surface of the pedestal by an adhesive. Fix the side edges of the fabric to the perimeter of the pedestal with compound or fasteners, etc. Examples of prior art with such a structure include Japanese Patent Application Publication No. 54-177764, Publication No. 54-177766, Publication No. 57-46939, Publication No. 59-9742, Japanese Patent Publication No. 60 - Publication No. 2046, Design No. 559923, etc.

However, since the above-mentioned prior art brush and applicator are assembled using an adhesive, desired strength cannot be obtained until the adhesive is hardened, or productivity is deteriorated due to the presence of an organic solvent or the like in the adhesive. That is, since the desired strength cannot be obtained before the adhesive is hardened, even in a product form, the material for forming the treatment portion from the handle is in a state of being easily detached, and a hardening process is required. In addition, since the adhesive contains an organic solvent that is toxic to the human body and highly flammable, it is necessary to install a sufficient exhaust device to prevent damage to the health of the operator, and strict attention must be paid to pyrotechnics.

In addition, although a structure that does not use an adhesive, such as a blackboard eraser, has been proposed, in this case, a metal band is attached to the periphery of the pedestal, and fixing members such as screws are driven in to fix it, so the assembly work is difficult. Special processing and equipment are required, the productivity is poor, and the cost is high.

On the other hand, the glazing operation of the vehicle body is the operation of applying a water-repellent treatment agent such as liquid or semi-solid wax to the surface of the vehicle body to spread it thinly, and the operator needs at least Prepare applicators such as sponges, cloth tools for thinly spreading and wiping off water-repellent treatments such as wax contained in containers, and disposable gloves, which take up a lot of space if you want to always keep these items in your luggage , which gets in the way due to infrequent use.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a surface treatment device that does not require adhesives, welding, etc., is easy to assemble, and has high productivity.

Another object of the present invention is to provide a surface treatment device that does not require a coating device, wax, cloth, etc., and is suitable for polishing a vehicle body.

Contents of the invention

In order to achieve the above object, the surface treatment device of the present invention is composed of a treatment part material, a handle, and an annular joint member.

(In this specification, a wet type surface treatment device refers to a surface treatment device in which wax, detergent, etc. are impregnated in a treatment member, and a dry type surface treatment device refers to a surface treatment device in which no substance is impregnated in a treatment member.)

This surface treatment device (glazing agent coating device) 1 is basically composed of treatment part materials (2, 3), an annular joint member 4, and a handle 5. As mentioned above, the glazing agent is contained in the continuous porous elastic body 2. Therefore, there is also a cover member 6 that prevents wax from adhering to the treatment part due to unintentional contact before use, and prevents evaporation of wax, detergent, etc. impregnated in the treatment part.

The configuration of each member will be described below.

The treatment part material forms the treatment part 11 which is in contact with the surface to be treated (in this case, the body of a motor vehicle) during use, and is made of a continuous porous elastic body 2 and a fibrous film 3 covering its surface. In the case of a type surface treatment device, nothing is impregnated, but in the case of a wet type product, a polishing agent, a detergent, etc. are impregnated (stored) inside the continuous porous elastic body 2 .

In the illustrated embodiment, the continuous porous elastic body 2 is a so-called sponge, that is, a soft molded body having fine continuous voids inside, and the continuous voids serve as storage spaces for polishing agents and the like in wet products. The glazing agent, detergent, etc. that are absorbed can be in any state of liquid, solid, or emulsion such as wax, polishing agent, and cleaning agent. In the case of solid state, it can be melted into liquid state first, and then processed Impregnated to absorb.

In the illustrated embodiment, the fibrous film 3 can use cloth, non-woven fabric, etc. that allow the polishing agent absorbed in the above-mentioned continuous porous elastic body 2 to pass through, and it is preferable to have high durability especially against friction. and durability against tensile stress, in this embodiment, muslin (extremely thin cotton or linen with a coarse mesh) was used. Various products are commercially available as muslin, and it can be appropriately selected from products with various properties made of materials such as acrylic/polyester and acrylic/rayon.

The ring-shaped joint member 4 is a member that pushes the ends of the above-mentioned treatment part materials (2, 3) into the ring-shaped groove 53 of the handle 5 described later and fixes them integrally with its front end, and only the ends of the fibrous membrane 3 may be fixed. Push in to secure. The annular joint member 4 is formed into an annular shape from a thin-walled rectangular plate, but its specific structure is determined in accordance with the annular groove 53 described later.

The cover member 6 has the protruding part 61 which covers the treatment part 11 which absorbs the polishing agent as described above, and is used to prevent wax from adhering and preventing drying due to unintentional contact before use. A molded product made of transparent plastic. The mounting portion 62 is formed slightly smaller than the outer peripheral edge of the annular groove 53 constituting the handle 5, and is held by the handle by press-fitting.

The surface treatment device 1 of this embodiment is constituted by assembling the treatment part materials (2, 3), the ring-shaped joint member 4, the handle 5, and the cover member 6, each of which has a simple structure, and the assembly is also extremely easy.

That is, at least the end of the fibrous film 3 of the treatment part material is pushed into the annular groove 53 of the handle 5 by the front end of the annular engaging member 4, so that the annular engaging member 4 is fitted into the annular groove 53, so that the treated portion can be processed. The portion 11 is supported by the base 51 and can be integrally fixed to the handle 5 . That is, the end (folded portion) of the treatment portion material (at least the fibrous film 3 ) pushed into the annular groove 53 is sandwiched by a very small gap between the side wall surface constituting the annular groove 53 and the annular joint member 4 state to prevent prolapse. Furthermore, the front end (engagement protrusion 42 ) of the ring-shaped engagement member 4 is configured to bite into the treatment portion material (at least the fibrous film 3 ) so that it can be prevented from coming out of the annular groove 53 .

Finally, the mounting portion 62 of the cover member 6 is fitted to the outer peripheral edge 59 of the seat 51 constituting the annular groove 53 of the handle 5 . The radial dimension of the mounting portion 62 is formed to be about 0.1-0.4 mm smaller than the outer peripheral edge 59, and it is pressed into the outer peripheral edge 59 of the handle 5 to elastically deform the two members. The cover member 6 is stretched and the handle is compressed. The outer peripheral edge, for tight embedded.

When in use, the cover member 6 is taken off, the grip part 54 of the handle 5 is held, and the treatment part 11 is pushed into contact. When it comes to the vehicle body, the treatment unit 11 is sandwiched between the pedestal 51 and the vehicle body, and the polish absorbed in the treatment unit 11 oozes out to coat the surface of the vehicle body in a very thin layer of polish.

When forming the above-mentioned treatment part 11, although not shown in the figure, it is also possible to arrange a layer of natural or synthetic polymer material between the continuous porous elastic body 2 and the fibrous membrane 3 in a layer of about 0.5-2mm. Powder layer. The powder layer has softness and elasticity to the extent that it does not damage the working surface, does not interact with the polishing agent, and does not adhere to the working surface, and the movement between the particles and between the particles and the fibrous film is within a certain range. The degree is free, and it is powder of protein such as leather, synthetic leather, β-starch colloidal particles, less adhesive rubber such as polytetrafluoroethylene (Teflon), soft synthetic resin, etc., with a particle size of about 5-500 μm.

As mentioned above, in this example, since the semi-solid wax at normal temperature is absorbed as the glazing agent, it will not flow out, but since the wax contains volatile components, it is necessary to prevent its volatilization. If it is liquid, it needs to be prevented from flowing out, but since the mounting portion 62 of the above-mentioned cover member 6 and the outer peripheral edge 59 of the annular groove 53 constituting the handle 5 are tightly fitted to form an airtight state, the above-mentioned volatilization and leakage of the liquid can be prevented. .
