Abstract

When a paint finish is applied to the surface of an automobile, a buff 1 made of sponge is bonded to a buff mount 2 with a hook-and-loop fastener, and the buff is attached to a polisher 3 and is electrically rotated to polish. However, as the buff 1 becomes thinner, the buff mount 2 made of cured rubber comes into contact with the painted surface and damages it. Therefore, Buff 1 was discarded before it became too thin.
A buff intermediate mount 4 having the following structure interposed between a buff 1 and a buff mount 2 is proposed. That is, it has a structure in which a columnar soft sponge 1A having a hole 1B formed in the center is the main body, a hook-and-loop fastener 4E is stuck on the upper surface, and a hook-and-loop fastener 4C is stuck on the lower surface. When this is interposed, even if the buff 1 is used until it becomes thin, it is separated only by the thickness of the buff intermediate mount 4, so that the buff mount 2 does not damage the painted surface.

Description

[0001]
[Technical field to which the invention belongs]
The present invention relates to a buff intermediate mount used for attaching a buff to a polisher for polishing at the time of sheet metal painting finish or the like.
[0002]
[Prior art]
At the time of finishing after painting an automobile, a buff is attached to a polisher, which is an electric tool, and is rotated at a high speed to polish a painted surface.
FIG. 3 is a diagram showing a conventional component for attaching a buff to a polisher. In FIG. 3, 1 is a buff, 1A is a sponge body, 1B is a hole, 1C is a hook-and-loop fastener, 1D is a hole, 2 is a buff mount, 2A is a pad, 2B is a hook-and-loop fastener, 2C is a hole, 2D is a connecting part, 3 is a polisher, 3A is a rotating shaft, and 3B is a power switch.
1-1 is a buff 1 drawn so that the lower surface can be seen.
[0003]
The buff 1 has a columnar shape as a whole, and the main body thereof is the sponge body 1A. A hole 1B is formed in the center of the sponge body 1A. A hook-and-loop fastener 1C is attached to the lower surface of the sponge body 1A, and a hole 1D is formed in the center thereof.
The polisher 3 is an electric tool. When the power switch 3B is turned on, the built-in motor rotates and the rotating shaft 3A rotates.
[0004]
The buff mount 2 includes a pad 2A, a hook-and-loop fastener 2B attached to the upper surface thereof, and a connecting portion 2D attached to a lower portion of the pad 2A.
The pad 2A is made of a cured rubber or the like, has an upper surface formed into a circular flat surface, and a central portion of the lower surface formed into a slightly raised shape. The hook-and-loop fastener 2 </ b> B is attached to be attached to and detached from the hook-and-loop fastener 1 </ b> C of the buff 1. A hole 2C is provided in the center of the hook-and-loop fastener 2B, and serves as a mark for positioning when the buff 1 is bonded. The connecting portion 2D is a portion for connecting to the rotating shaft 3A of the polisher 3.
[0005]
The hole 1B is formed in the same size from the upper surface to the lower surface of the sponge body 1A. The hole 1D is a hole formed in the center of the hook-and-loop fastener 1C, and is smaller than the hole 1B.
The reason why the holes 1 </ b> B and 1 </ b> D are provided is that when the buff 1 is bonded to the buff mounting base 2, it is positioned so that it can be properly bonded to the center of the upper surface of the buff mounting base 2. That is, if the user holds the buff 1 and looks down through the hole 1B, a hole 1D smaller than the hole 1B can be seen, but the bonding is performed such that the hole 1D is located at the center of the hole 2C. Then, the buff 1 can be adhered to the center of the upper surface of the buff mount 2, and when the buff 1 is rotated by the polisher 3, the buff 1 can be rotated in a well-balanced manner without eccentricity.
[0006]
The hole 1D also has a role of cooling the sponge body 1A. During use of the buff 1, frictional heat is generated in the sponge body 1A due to friction with the coating surface, but the hole 1D releases the frictional heat and cools the sponge body 1A. From the viewpoint of cooling, the larger the hole 1B is, the better. However, if the hole 1B is too large, the polishing function is hindered.
The hole 1D may be smaller than the hole 1B since the lower part can be seen from there (to visually recognize the hole 2C) and only needs to be a landmark.
[0007]
FIG. 4 is a diagram illustrating a state in which the buff 1 is attached to the polisher 3. FIG. 4 (1) shows a situation when the buff 1 is still near new, and FIG. 4 (2) shows a situation when the buff 1 is worn down considerably.
When new, the buff 1 has a thickness T ₁ (several centimeters) as shown in FIG. When polishing a vehicle body painted with such a buff, a polishing agent such as a compound is applied, and the buff 1 is rotated at a high speed and polished. However, when doing such polishing work out what week, buff 1 came worn gradually, over time, as shown in FIG. 4 (2), comes as thin as the thickness T _2.
[0008]
[Problems to be solved by the invention]
(problem)
Buff 1 had the problem that it had to be disposed of before it was too thin.
(Explanation of the problem)
Even if the buff 1 becomes thin, it is still made of a sponge body, so that it can be used theoretically. However, during the polishing work, there is a scene where the surface of the buff 1 must be polished while being tilted and pressed against the vehicle body.
[0009]
In such a situation, the thinned buff 1 may be compressed and further thinned, causing the buff mount 2 to hit the painted surface. Then, since the buff mount 2 is made of a hard material such as hardened rubber, the painted surface will be damaged.
In order to avoid such a situation, it is a fact that the buff 1 is discarded before it becomes too thin, which is not preferable from the viewpoint of resource saving and also from the viewpoint of environmental protection of reducing waste. It was not.
An object of the present invention is to solve the above problems.
[0010]
[Means for Solving the Problems]
In order to solve the above problem, the present invention newly provides a buff intermediate mounting base. The buff intermediate mount includes a column-shaped sponge body having a first hole formed in a central portion, and a portion of an upper surface of the sponge body, which is inside the outer periphery and outside the first hole. And a second hook-and-loop fastener having a second hole in the center and a second hook-and-loop fastener bonded to a portion inside the outer periphery of the lower surface of the sponge body. The second hook-and-loop fastener is detachably adhered to the hook-and-loop fastener of the table, and the buff hook-and-loop fastener is detachably adhered to the first hook-and-loop fastener for use.
[0011]
(Operation)
The buff intermediate mount of the present invention is mounted between the buffs and the buff mount when a buff to be used for painting is mounted on the buff mount. Therefore, even if the buff is worn down and thinned, the buff and the buff mount are still separated by the thickness of the buff intermediate mount. What is exposed on the buff intermediate mount to the outside during the polishing operation is a soft sponge body.
Therefore, even if the buff intermediate mount comes into contact with the painted surface, there is no risk of damaging the surface, and the buff can be used until it becomes thin.
[0012]
[Embodiment of the invention]
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a diagram showing parts for attaching a buff to a polisher using the buff intermediate attachment base of the present invention. The reference numerals correspond to those in FIG. 3, 4 is a buffing intermediate mount, 4A is a sponge body, 4B is a hole, 4C is a surface fastener, 4D is a hole, and 4E is a surface fastener. Reference numeral 4-1 denotes a buff intermediate mounting base drawn so that the lower surface can be seen.
3 are the same as those in FIG. 3, and the description thereof will be omitted.
[0013]
The difference from the conventional example of FIG. 3 is that a buff intermediate mounting base 4 is interposed between the buff 1 and the buff mounting base 2 for mounting.
The buff intermediate mount 4 includes a sponge body 4A having a hole 4B formed in the center, and a hook-and-loop fastener 4E bonded to a portion of the upper surface of the sponge 4A, which is inside the outer periphery and outside the hole 4B. And a hook-and-loop fastener 4C having a hole 4D in the center.
[0014]
The sponge body 4A is best made of the same material as that of the sponge body 1A, but may be any material that does not damage the surface of the sponge body when the sponge body rotates and comes into contact with the surface. The hole 4B is a hole for performing the same function (cooling function, positioning function) as the hole 1B.
The hook-and-loop fastener 4C is for attaching and detaching to and from the hook-and-loop fastener 2B of the buff mount 2, and is the same as the hook-and-loop fastener 1C. The hole 4D formed in the center of the hook-and-loop fastener 4C is a hole for performing the same function (positioning function) as the hole 1D of the buff 1.
The hook-and-loop fastener 4E is for attaching and detaching to and from the hook-and-loop fastener 1C of the buff 1, and is the same as the hook-and-loop fastener 2B.
[0015]
Adhesion and connection of each component in FIG. 1 are performed as follows.
{Circle around (1)} First, the buff intermediate mount 4 is adhered to the upper surface of the buff mount 2 in the following manner. The hook-and-loop fastener 2B and the hook-and-loop fastener 4C are bonded so that the hole 4D is located at the center of the hole 2C by looking down from the hole 4B.
(2) Next, the buff 1 is adhered to the upper surface of the buff intermediate mount 4 in the following manner. The hook-and-loop fastener 4E and the hook-and-loop fastener 1C are adhered so that the hole 1D is located at the center of the hole 4B, looking downward from the hole 1B.
(3) The rotating shaft 3A of the polisher 3 is connected to the connecting portion 2D of the buff mounting base 2.
[0016]
FIG. 2 is a diagram showing a state in which the buff 1 is mounted on the polisher 3 via the buff intermediate mounting base 4 of the present invention. The reference numerals correspond to those in FIG. 4, and t is the thickness of the buff intermediate mount 4.
FIG. 2 (1) shows a situation when the buff 1 is still near new, and FIG. 2 (2) shows a situation when the buff 1 is worn down considerably.
[0017]
When buff 1 is new, as shown in FIG. 2 (1), high speed to contact the thickness of the sponge body material where not to damage the vehicle body surface even is the buff 1 thickness T ₁ and buff intermediate There is also (T ₁ + t) which is the sum of the thicknesses t of the mounting base 4. Even though sufficient even thickness T _1, since it is not certain more, be contacted by tilting the buff 1 for painted surfaces, buff mount 2 may of course not in contact with the painted surface.
[0018]
On the other hand, in the case of FIG. 2 (2) the thickness of the buff 1 came reduced to T ₂ while in use, even at that stage, the thickness of the sponge body material, the thickness T ₂ of the buff 1 buff Only (T ₂ + t), which is the total thickness t of the intermediate mount 4, remains. Therefore, the thickness of the sponge body total even at the _second thickness T ₂ is equivalent small is (T 2 _{+ t)} is from, be contacted by tilting the buff 1 for painted surfaces, buff mount 2 is painted surfaces There is no danger of contact. The value of the thickness t of the buff intermediate mount 4, considering the thickness of the buff 1 new is T _1, it is sufficient to slightly smaller value than its thickness T _1. Then, the buff 1 can be used up to the point where the sponge body 1A is almost worn away.
[0019]
In FIG. 2, only one type having a thickness of t is shown as the buff intermediate mount 4, but it may be of various thicknesses. Several types of buffing intermediate mounts 4 having different thicknesses may be prepared, and the buffing intermediate mounting bases 4 may be selectively used in accordance with the situation of the buff 1 being worn down.
For example, three types of buffing intermediate mounts 4 having thicknesses of t ₁ , t ₂ , and t ₃ are prepared in order from the thinner one, and when the buff 1 is new, the buffing intermediate mount 4 of the thinnest t ₁ is prepared. use the, when the buff 1 came worn out a little bit by using the buff intermediate mount 4 of the middle of the thickness t _2, the buff intermediate mount 4 of the thickest t ₃ when he came worn badly Use differently depending on how you use it.
In this way, the total thickness of the buff 1 and buff intermediate mount 4 is always so remains relatively close thickness to the thickness T ₁ of the buff 1 new, usability is bad for workers .
[0020]
[Effect of the invention]
As described above, according to the buff intermediate mount of the present invention, it is possible to use the buff until it is much thinner than before. As a result, the products (resources) called buffs can be used up to the point where they can be used, and resources can be saved, and the amount discarded as garbage can be reduced to contribute to environmental protection.
