JPS5942142Y2 - Painting roller brush - Google Patents

Description

[Detailed explanation of the idea] (Target of invention, industrial application field) The invention is used in the field of liquid application.

More specifically, it is used in the field of applying paints, glues, adhesives, etc.

The present invention relates to an improvement in a coating roller run that retains a coating material within the roller and exudes the coating material from the roller surface.

(Prior art) A coating roller brush that retains paint inside the roller and exudes the paint from the roller surface has already been developed since 1973.
It is described in Publication No. 974.

However, the application roller brush described in Japanese Utility Model Publication No. 35-16974 requires the following procedure when used.

(a) Remove the screws and remove the bottom plate that serves as the lid.

(b) Inject the paint into the cylinder through the hole in the bottom plate that forms the hole in the side wall of the roller. (c) Fit the bottom plate that forms the back cover and tighten with screws. This has the following drawbacks.

(b) Hand work is required to introduce the paint into the roller, so even if it is only used once, when introducing the paint from the second time onwards, be sure to handle it with a screw or a direct child such as the bottom plate. You have to, and your hands get dirty with paint.

(b) When applying paint, you often work at heights, and if you use both hands to introduce the paint, there is a risk of falling.

e'9 The process of introducing the paint takes too much time and is troublesome because the screws are loosened, the lid is removed, paint is poured in, the lid is closed and screwed back on again.

) When the brushes become old, the entire roller bluff must be discarded or replaced in a tedious manner.

(Problems to be solved by the present invention) The problems to be solved by the present invention are (a) to be able to store paint in the roller without getting your hands dirty at all; (b) to be able to store paint in high places. Even in the case of coating work, it is possible to eliminate the risk of falling by not requiring both hands to introduce the paint, and (c) to shorten the time for introducing the paint by making it possible to introduce the paint in one step. (b) Even if the brush of a roller brush becomes unusable, there is no need to discard the entire roller brush, and only the brush body can be replaced, thereby reducing waste.

(Means for solving the problems and their effects) The technical means of the present invention taken to solve the above problems are as follows.

In a coating roller brush that has a hollow cylindrical body with a large number of through holes in the peripheral wall, one end closed and the other end open, (a) a valve is attached to the support shaft to close the opening of the cylindrical body; (b) Either the cylindrical body or the valve is biased by an elastic body to normally close the opening of the cylindrical body; (c) the cylindrical body or the valve is Either one of the cylinders or the valve must be attached so as to be movable from side to side on the support shaft, and (2) When either the cylinder or the valve is moved against the elasticity of the elastic body when introducing the coating material. (e) It is formed in a cylindrical shape and has a brush body that is removably attached to the outer periphery of the cylindrical body and covers a through hole formed in the peripheral wall of the cylindrical body. What I am doing is .

When introducing paint, either the valve or the cylindrical body is moved on the support shaft against elasticity to introduce the paint, and when the brush becomes old, it can be replaced.

(Example) The present invention will be described in more detail based on an example shown in the drawings.

In FIGS. 1, 3, and 4, reference numeral 1 denotes a hollow cylindrical roller, which has a large number of paint outlet holes 2 penetrating its peripheral wall.

The roller 1 has side plates 3 on both sides.

The side plates 3 are for sealing off the row 21 and allowing paint to be stored inside the roller 1, and are sealed on both sides of the roller 1 or fitted as a lid to prevent paint from leaking.

A paint inlet 4 is formed in the side plate 3 on the tip side among the side plates 3.

A support shaft 5 is provided passing through the roller 1.

The support shaft 5 supports and rotates the roller 1, and has a grip portion 9 at its end.

The roller 1 is mounted on a support shaft 5 so as to be movable left and right.

In order to prevent the paint introduced into the row 21 from flowing out, a lid body 6 which is a valve for blocking the paint inlet 4 is provided at the tip of the support shaft 5.
is attached.

Then, in order to prevent the paint stored in the roller 1 from leaking, a coil spring 8, which is an elastic body, is attached to the base of the support shaft 50, and the roller 1 is pressed against the lid body 6, so that the paint inlet port 4 is normally blocked. ing.

When attaching the lid 6 to the support shaft 5, if the lid 6 and the roller 1 are made of a material or have a structure that allows them to slide smoothly even when they are in close contact, the lid 6 should be attached to the support shaft 5. It may be fixed to the tip of the lid 5, but if not, the lid 6
is attached so as to rotate in close contact with the row 21.

As an example of a method for mounting the lid 6, there is a method in which the tip of the support shaft 5 is made thinner than the other parts and the lid 6 is held between a split pin, as shown in FIG. 1, but the method is not limited to this method. It's not a thing.

As shown in FIG. 6, the lid 6 is designed to prevent the roller 1 from getting in the way when the roller 1 is moved to the right of the support shaft 5 using the bottom plate of a paint bucket or the like. It is formed smaller than the external shape.

With the above configuration, when the roller 1 is moved against the elasticity of the coil spring 8 when introducing the paint, the roller 1 and the lid body 6 are separated.

A brush body 10 is attached to this row 21.

As shown in FIG. 2, the brush body 10 has a knitted base fabric with a slightly longer raised surface.

In order to bring the brush body 10 into a raised state, for example, a group of piles may be knitted together with the base fabric and the piles may be trimmed, or
There are methods such as scratching the surface of the base fabric with a wire brush or the like.

The brush body 10 is formed into a cylindrical body having a slightly smaller diameter than the roller 1.

Therefore, when the brush body 10 adheres to the roller 1, it adheres to the roller 1 in an extended state, and the stitches themselves widen, so that the paint flowing out from the row 21 can sufficiently reach the surface of the brush body 100.

An annular body 9 made of an elastic body such as a coil spring or rubber and having a diameter smaller than the diameter of the row 21 is attached to the periphery of both ends of the brush body 100.

Therefore, the brush body 10 can be easily attached to and detached from the roller 1 simply by expanding the annular body 9.

Further, since the brush body 10 is knitted and the annular body 9 made of an elastic body is made smaller in diameter than the row 21, the brush body 10 is in close contact with the roller 1 and does not shift during the coating operation.

The brush body 10 is not limited to the above structure, but may be formed in a cylindrical shape, can be attached to and detached from the outer periphery of the roller 1, and can cover the paint outlet hole 2 formed in the peripheral wall of the row 21. good.

FIG. 5 shows another embodiment of the roller 1, in which the peripheral edge of the roller 1 is made to protrude outward from the side plate 3 to form an annular projection 13,
Moreover, the lid body 6 is slightly curved.

In this case, the roller 1 is moved away from the lid 6 by the protruding portion of the annular protrusion 13, and the distance between the roller 1 and the lid 6 is widened, so that the paint can easily flow in and the periphery of the lid 6 is closer to the side plate. Closely adheres to 3.

7 and 8 also show other embodiments of the roller 1. FIG.

In this embodiment, the lid 6 is built into the row 21 and the support shaft 5 is
One end of the coil spring 8 is stopped, and the other end of the coil spring 8 is pushing the lid 6.

Then, the lid body 6 is pushed inward by the protrusion P to introduce the paint into the roller 1.

9 and 10 also show other embodiments of the roller 1, in which a coil spring 8 is built into the roller 1, one end of the coil spring 8 is stopped on the support shaft 5, and the other end of the coil spring 8 is used to cover the roller 1. It is pressed against body 6.

When introducing the paint, the roller 1 is moved to the right to open a space between the roller 1 and the lid 6.

In this embodiment, the coil spring 8 is placed inside the roller 1, so that even if paint adheres to the coil spring 8, it does not fall onto the object to be coated.

11 and 12 also show other embodiments of the row 21.

In this embodiment, a row 21 is attached to the tip side of the support shaft 5, and a lid body 6 is attached to the base side of the support shaft 50.

A coil spring 8 is interposed between the roller 1 and the lid 6 to urge the lid 6 toward the row 21 and bring the lid 6 into close contact with the roller 1 to prevent paint from leaking.

Note that when introducing the paint, the lid body 6 is moved to the right.

When using the present invention, the brush body 10 is attached to the roller 1.

Then, as shown in Figure 6, insert the roller brush into the bucket B containing the paint, press the front corner of the roller 1 against the bottom of the bucket B, move the roller 1 to the right in the figure, and remove the lid. 6
A gap is opened between the rollers 1 and 1, and the paint is introduced into the roller 1.

When the roller brush is taken out from the bucket B after the introduction of the paint, the roller 1 is urged toward the lid body 6 side by the elasticity of the coil spring 8 and closes the paint introduction port 4 without touching it.

Then apply the paint to the object.

(Effect of idea) Since the present invention has the above configuration, it produces the following effects.

(a) Since the paint can be introduced into the roller simply by moving the roller or valve within the paint container, there is no need to touch the roller or the like, and your hands will not get dirty at all.

(b) Even when coating work is performed at high places, there is no risk of falling because both hands are not required to introduce the paint.

(c) Since the paint can be introduced in one step of moving either the valve or the cylindrical body on the support shaft against elasticity, the time for introducing the paint can be shortened.

2) Even if a roller brush becomes unusable, there is no need to dispose of the entire roller brush; just replace the brush body and it can be used as a new roller brush.
