The scraper 1 of this embodiment is a scraper including a handle portion 2 and a flat plate-shaped spatula portion 3 fixed to the handle portion 2, and the spatula portion 3 has an insertion hole 4 penetrating from the front to the back surface. A slit 5 cut out from the side surface of the spatula portion 3 to the insertion hole 4 is provided.

The coating roller 100 is generally used in the past, and has a handle 130, a cylindrical roller 110, one end fixed to the handle 130 and the other end connected to the roller 110 to rotate the roller 110. It is provided with an arm portion 120 that can be freely supported. The arm portion 120 is a round bar-shaped member, and is bent in a dogleg shape to connect the handle portion 130 and the roller portion 110 arranged in a direction substantially perpendicular to the axial direction of the roller portion 110. .. The roller portion 110 includes the above-mentioned core portion 112 and a substantially cylindrical painted portion 111 attached to the outer periphery of the core portion 112, and pushes the painted portion 111 to which paint has adhered or absorbed to an object such as a wall surface. It can be painted by hitting and rolling.

In the scraper 1 of this embodiment, the insertion hole 4 has an inner peripheral surface 41 with which the roller portion 110 is in sliding contact when the roller portion 110 of the coating roller 100 is inserted. Further, in the scraper 1 of the present embodiment, the slit 5 has an opening 52 at which the arm portion 120 supporting the roller portion 110 allows the scraper 1 to be pulled out from the coating roller 100.

That is, the inner diameter of the insertion hole 4 is formed so that the roller portion is in sliding contact with the inner peripheral surface 41 of the insertion hole 4 when the roller portion 110 of the coating roller 100 is inserted. Further, the groove width of the slit 5 is formed so as to allow the arm portion to enter. Hereinafter, each component will be described in detail.

The scraper 1 includes a pair of wooden handle portions 2 on the front side and the back side, and a steel spatula portion 3, and the spatula portion 3 is sandwiched between the pair of handle portions 2 from the front and back sides to form a metal fitting. It is formed as one by fixing with 6. The spatula portion 3 has a flat plate shape, and a blade 7 is formed at the tip (upper edge) of the spatula portion 3. In this embodiment, the scraper 1 is a single-edged blade, and in the description of this embodiment, the surface on the side where the blade is provided is the front side.

A circular insertion hole 4 is bored in the spatula portion 3 slightly closer to the handle portion. In this embodiment, the insertion hole 4 is provided at a position (center on the left and right) at the same distance from the left side and the right side of the spatula portion. That is, the insertion hole 4 is a circular hole having a center point at the center of the left and right sides of the spatula portion 3. The diameter of the insertion hole 4 is the size at which the outer peripheral side of the roller portion 110 slides into the inner peripheral surface 41 of the insertion hole 4 when the roller portion 110 of the coating roller 100 is inserted (see FIG. 3), in other words, coating. The diameter is smaller than the diameter of the roller portion 110 including the portion 111, and is an inner diameter into which the coated portion 111 having cushioning properties and capable of shrinking can be inserted. In this embodiment, the insertion hole 4 is a circular hole, but the shape of the insertion hole may be another shape such as a quadrangle or a triangle. In this embodiment, since the insertion hole 4 is circular, it is easy to uniformly remove the paint.

Further, the spatula portion 3 is formed with a slit 5 notched from the right side surface of the spatula portion 3 to the insertion hole 4. The side end of the spatula portion is referred to as an opening 52, and the end portion on the side communicating with the insertion hole 4 is referred to as a communication portion 51. In this embodiment, the communication portion 51 communicates with the insertion hole 4 with a width equal to or less than the radius of the insertion hole. The groove width of the slit 5 is formed to be larger than the width that the arm portion 120 of the coating roller 100 can enter, in other words, the diameter of the arm portion 120 formed by bending a round bar. In this embodiment, the slit 5 is provided with an opening 52 on the right side surface side of the spatula portion 3 so that it can be easily used for a right-handed person, but the slit 5 is provided on the left side surface side of the spatula portion 3. An opening may be formed. Further, the slit 5 may be formed so that the side surface of the groove is formed in parallel with the groove width constant from the opening 52 to the communication portion 51, or the groove width on the opening side may be widened. ..

The scraper 1 may be manufactured by drilling or the like on a scraper having a handle portion and a flat plate-shaped spatula portion fixed to the handle portion, which is generally commercially available. It is excellent in terms of manufacturing cost because it can be made by processing a commercially available scraper.

The dimensions of each part of the scraper 1 are arbitrary, but the spatula portion 3 and the handle portion 2 are formed so as to maintain the function as a scraper such as peeling off paint and rust and opening a paint can. Is desirable. In the scraper 1 of this embodiment, the blade length of the blade portion 7 is about 90 mm, and the length of the spatula portion is about 8.4 mm at the left and right central portions. The diameter of the insertion hole 4 is about 25 mm, and the groove width of the slit 5 is about 8 mm on the communication portion 51 side, but may be about 10 mm. In this embodiment, the groove width on the opening 52 side of the slit 5 is about 3 mm wider than that on the communication portion 51 side, but it may be the same as the groove width on the communication portion 51 side. The dimensions of each part are not limited to the dimensions in this embodiment and can be set arbitrarily.

Next, a method of using the scraper 1 when it is used as a tool for removing the paint attached to the roller portion 110 of the coating roller 100 will be described. Since the usage method for exerting the conventional functions such as painting and peeling off rust is the same as the conventional method, the description thereof will be omitted.

As described above, since the paint gradually solidifies in about 1 hour, it is desirable to remove the paint on the roller portion promptly.

When the scraper 1 of the present embodiment is used for removing paint in order to take a break during use of the coating roller 100, first, one hand (for example, the right hand) holds the coating roller 100, and the other hand (for example, the left hand). ), And the coating roller 100 is held, for example, with the tip side of the roller portion 110 facing up and the root side of the roller portion 110 facing down.

After that, as shown in FIG. 3, the tip of the roller portion 110 is inserted into the insertion hole 4 of the scraper 1 and pushed in, so that the roller portion 110 is in sliding contact with the inner peripheral surface 41 of the insertion hole 4, thereby causing the roller. The paint adhering to or absorbed by the painted portion 111 of the portion 110 is sequentially squeezed out to one surface (lower side in FIG. 3) of the spatula portion 3. If a paint can or the like is placed below the roller portion 110, the squeezed paint can be received.

On the back side of the spatula portion 3 of the scraper 1 (the lower surface of the scraper 1 in FIG. 3), the paint scraped off from the roller portion 110 accumulates around the insertion hole 4 and then falls down. Since the spatula portion 3 around the insertion hole 4 acts like an extremely wide flange, there is no possibility that the accumulated paint will turn to the upper surface and reattach to the roller portion 110. Therefore, the removal work can be completed speedily without the trouble of removing the reattached paint again.

In this embodiment, the spatula portion 3 is inserted into the roller portion 110 from the back surface side (the side without the blade portion), but the spatula portion 3 may be inserted from the front side.

The scraper 1 is pushed to the root side of the roller portion 110 of the coating roller 100 and moved to the arm portion 120 side as shown in FIG. 4, and then the scraper 1 is separated from the coating roller 100 through the arm portion 120 through the slit 5. .. FIG. 4 is a view seen from the root side (lower side) of the roller portion 110. When the spatula portion 3 hits the arm portion 120 when lowered to the arm portion 120 side, the scraper 1 is rotated clockwise from the front to the front, and the arm portion 120 is inserted into the slit 5 as shown in FIG. Change the direction of scraper 1 and pull it out. The arm portion 120 may be rotated in the opposite direction. You may hold the coating roller 100 in your left hand and the scraper 1 in your right hand so that the front side faces up, and pull out the scraper 1 from the front to the front side. Alternatively, the coating roller 100 may be held in the left hand and the scraper 1 may be held in the right hand so that the back side faces up, and the scraper 1 may be pulled out from the front side to the front side.

According to the above steps, it is possible to quickly remove the paint adhering to the roller portion 110 of the coating roller 100. If there is paint left after being removed in one step, such as some paint hitting the slit 5 part of the roller portion 110, the insertion angle of the scraper 1 with respect to the painting roller 100 is changed, and the same step is performed again. I do.
