Description

[Detailed Description of the Invention] <Industrial application field> The present invention relates to a paint roller used for coating paint on the interior, exterior, and walls of buildings, etc., and is held on a horizontal rod. It prevents the paint from entering the elastic inner cylinder attached to the inner periphery of the paint infiltration roller from the outside, and thus prevents the paint infiltration roller from sliding outwards or escaping during use. This is a paint roller that can be prevented and can be used by simply removing the paint infiltration roller from the rotating body and easily attaching and fixing the paint infiltration roller for another color to the rotating body when changing the color of the paint.

<Prior Art> A commonly used paint roller is an inner circular support made of hard synthetic resin with an inner end flange that bends the front end of a metal rod attached to the handle to form a horizontal rod. To the outer circular support made of hard synthetic resin, the ends of several elastic rods made of metal whose central part is inflated outwardly are fixed to form a rotating body. , The outer circular support is inserted into the horizontal rod and rotatably attached, and the wool and synthetic resin paint infiltration rollers attached to the outer peripheral portion of the elastic inner cylinder made of cardboard The elastic rod of the book is pressed and inserted, and the inner surface of the elastic inner cylinder of the paint infiltration roller is brought into contact with the inner end flange of the inner circular support.

However, the paint infiltration roller is held by the elasticity of the elastic inner cylinder made of cardboard on its inner peripheral surface and the elasticity of several elastic rods made of metal of the rotating body. While using it, the paint gradually penetrates from the outer peripheral surface of the outer circular support and the inner peripheral surface of the outer side of the corrugated cardboard elastic inner cylinder of the paint infiltrating roller, Eventually, the paint adheres to the inner peripheral surface of the elastic inner cylinder and the elastic rod so that both of them can slide, so that the paint infiltration roller slides outward along with the elastic inner cylinder during use of the paint roller. Not only does it become difficult to use, but it eventually escapes from the elastic rod, so the user must move the paint wetting roller inward one by one and move the inner end surface of the elastic inner cylinder of the paint wetting roller inward. It had to be used in contact with the inner end flange portion forms support. At the same time, as the paint wetting roller slips outwards and the paint wetting roller is repeatedly moved inward to correct it, the elastic force of the elastic rod weakens and the paint wetting roller moves outward. However, there is a drawback in that it tends to skid.

<Problems to be Solved by the Invention> The present invention has been devised in view of the above-mentioned circumstances, in which the ring of the stopper is provided on the inner peripheral surface and the outer surface of the elastic inner cylinder of the paint infiltration roller from the outer surface thereof. Since the inner surface of the outer circular thin plate is brought into close contact with the outer surface of the elastic inner cylinder by press-fitting it in the slight inner space between the outer peripheral surface of the rectangular support and the inner surface of the elastic inner cylinder, The paint roller is designed to prevent the paint from penetrating into the housing, thus ensuring that the paint moisturizing roller is held by the elastic rod so that it does not skid outwards, and prevents the paint roller from escaping. is there.

<Means for Solving the Problems> That is, the stopper of the paint roller of the present invention is such that a ring having a smaller diameter than the outer circular thin plate is formed on the inner side surface of the outer circular thin plate and unevenness is formed on the front and back surfaces of the ring. The main point is to provide.

<Operation> A ring having a smaller diameter than the outer circular thin plate formed on the inner side surface of the outer circular thin plate, and having irregularities on the front and back surfaces,
It is press-fitted into a slight gap between the outer peripheral surface of the elastic inner cylinder of the paint infiltration roller and the outer peripheral surface of the outer circular support, and the inner side surface of the outer circular thin plate is By closely contacting with the outer surface, the paint is prevented from entering the elastic inner cylinder through the slight gap.

<Example> An example of the present invention will be described below.

19 is a stopper having the following structure. That is, 1 is an outer circular thin plate made of metal such as iron, copper, stainless steel, or aluminum alloy, or hard synthetic resin, and 2 is smaller in diameter than the outer circular thin plate 1, and is formed on the inner surface 1a thereof. Ring made of metal such as iron, copper, stainless steel, aluminum alloy, or hard synthetic resin,
Reference numerals 3a and 3b are irregularities provided on the front and back surfaces of the ring 2, and may be vertical irregularities as shown in FIGS. 1 and 2, or vertical helical irregularities, embosses, horizontal irregularities, etc. But it's okay. In short, the shape of the unevenness may be any shape as long as it is the catching surface of the unevenness.

In the figure, 4 is a handle, 5 is a metal rod, 6 is a horizontal rod at the tip thereof, 7 is an inner circular support made of a hard synthetic resin, 8 is an inner end flange portion provided on this, 9 is a hard rod. Outer circular support made of synthetic resin, 9a is an outer peripheral surface thereof, 10 is a plurality of elastic rods made of metal whose central portion is inflated outward, and the inner circular support 7 and the outer circular support are provided. Both ends are fixed to 9 to form a rotating body 11, and inner and outer circular support members 7 and 9 are rotatably fitted into the horizontal rod 6. Further, a stop plate 12 is attached to the inner end of the horizontal rod 6, and a nut 13 attached to the outer end of the horizontal rod 6
The rotating body 11 is held by the horizontal rod 6 so that it does not come out of the horizontal rod 6.

Reference numeral 14 is a cardboard elastic inner cylinder, 14a is an inner peripheral surface of the elastic inner cylinder, 15 is a paint infiltrating roller made of synthetic resin made of wool attached to the outer peripheral surface of the elastic inner cylinder 14, and the elastic inner cylinder 14 is attached to the rotating body 11 The elastic rods 10 are press-fitted into the outer peripheral portions of the elastic rods 10 against their elasticity, and the inner side surface 14b of the elastic inner cylinder 14 is brought into contact with the outer side surface of the inner end flange portion 8 of the inner circular support 7. Further, 14c is an outer surface of the elastic inner cylinder 14, 16 is a nut insertion hole provided in the outer circular support 9,
Reference numeral 17 denotes a closing lid of the nut insertion hole 16, and 18 denotes a slight gap formed between the inner peripheral surface 14a of the elastic inner cylinder 14 and the outer peripheral surface 9a of the outer circular support 9.

According to the present invention, as described above, the stopper 19 is formed by forming the ring 2 having a smaller diameter than the outer circular thin plate 1 on the inner surface 1a of the outer circular thin plate 1 and providing the unevenness 3a, 3b on the front and back surfaces of the ring 2. Therefore, when the stopper 19 is attached to the paint roller, the ring 2 portion is arranged in the state shown in FIG. 4 from the direction of the arrow in the figure to the inner peripheral surface 14a of the elastic inner cylinder 14 of the paint infiltration roller, The inner surface 1a of the outer circular thin plate 1 is press-fitted into a slight gap 18 formed between the outer circular support 9 and the outer peripheral surface 9a.
As shown in FIG. 5, the elastic inner cylinder 14 is closely attached to the outer surface 14c.

In this case, since the stopper 2 has the projections and depressions 3a and 3b on the front and back surfaces of the ring 2, the ring 2 includes the inner peripheral surface 14a of the elastic inner cylinder 14 and the outer circular support 9. The outer peripheral surface 9a is securely fixed. Therefore, the ring 2 rotates together with the outer circular thin plate 1 together with the rotating body 11 and the paint infiltration roller 15 without coming out from the slight gap 18 at all, and of course the paint infiltration roller 15 is infiltrated with the paint. Then, when painting, it rotates together.

Further, when replacing the paint infiltration roller 15 with another one in order to change the color, hold the metal rod 5 in one hand, hold the paint infiltration roller 15 in the other hand, and pull it strongly outward. It can be removed together with the stopper from the rotating body 11. And a paint infiltration roller 15 for another color
When attaching the to the rotating body 11, attach the stopper 19 to the outer space of the elastic inner cylinder 14 of the paint wetting roller 15 used previously.
It can be easily attached by simply pulling it out with a little force from 18, inserting another paint infiltrating roller 15 into the rotating body 11 by press fitting it as described above, and pressing the stopper 19 into the gap 18.

<Effect of Device> As described above, the stopper 19 is the inner side surface 1a of the outer circular thin plate 1.
Since a ring 2 having a diameter smaller than that of the outer circular thin plate 1 is formed on the front surface and the back surface of the ring 2, unevennesses 3a and 3b are provided, so that the ring 2 has an inner peripheral surface 14a of an elastic inner cylinder 14 and an outer surface. It is located in a slight gap 18 with the outer peripheral surface 9a of the rectangular support 9 and does not come into close contact with it and does not come off outward, and the outer surface of the elastic inner cylinder 14
Since the inner side surface 1a of the outer circular thin plate 1 is in close contact with the outer side surface 14c, the inner side surface 1a of the outer circular thin plate 1 is tightly fixed to the rotating body 11, and the paint penetrates into the elastic inner cylinder 14 from between the outer side surface 14c and the inner side surface 1a. There is no fear, therefore, unlike the conventional product, the elastic inner cylinder
The inner peripheral surface 14a of 14 does not slide laterally from the several elastic rods 10 of the rotating body 11 and the paint infiltration roller 15 does not slide outward or escape outward. Therefore, since the paint infiltration roller 15 does not hinder the use, it is possible to improve the coating efficiency, and to correct the slippage to the outside of the paint infiltration roller during use as in the conventional product. It is also possible to prevent the elastic rod from weakening the elastic force by repeating the inward movement of the elastic member so as to make it easier to skid. Also, the outer circular thin plate 1 of the stopper 19
Since the thickness is thin, the paint can be applied completely even when the paint is applied to the corners, and since the stopper is small and lightweight, it is suitable for mass production and easy to attach to the paint roller, and Can be offered at a low price. Further, in the present invention, the inner and outer circular supports at both ends of the rotating body 11
Elastic inner cylinders 7 and 9 made of a hard synthetic resin and having an inner diameter slightly larger than the outer diameters of the inner and outer circular support members 7 and 9.
Since 4 is used, the paint infiltration roller 15 can be smoothly removed together with the stopper 19 from the rotating body 11 when changing the color, and then the stopper 19 is once removed from the paint infiltration roller 15 and then another paint is applied. After the infiltration roller 15 is press-fitted and attached to the rotating body 11, the stopper 19 is press-fitted into the gap 18 as described above, which has the effect of being easily attached.
