FIG. 1 shows an embodiment of the roller type coating tool 100 according to the present invention. As shown in the figure, the roller type coating tool 100 is provided at the tip of the first arm 20 extending from the grip 10, the second arm 30 extending so as to branch from the middle of the first arm 20, and the tip of the first arm 20. It is mainly composed of a first roller 40 and a second roller 50 provided at the tip of the second arm 30.

The first arm 20 is made of, for example, a metal rod having a thickness of about 5 mm, and the root side thereof is integrally incorporated in the axial center portion of the grip 10, and the first bent portion 21 in a substantially central portion thereof. Is bent to the right at an angle of about 30 ° to 90 °. Further, the second bent portion 22 on the tip side of the first bent portion 21 is bent so as to be substantially parallel to the root side, and the third bent portion 23 on the tip side of the second bent portion 22 is bent. It bends to the left at a more approximately right angle.

The first roller 40 is detachably attached to the support shaft 24 on the tip side of the third bent portion 23. The first roller 40 is provided with a flexible coating layer 42 made of pile knitted fabric, pile woven fabric, or the like around a rotatable shaft center tube 41, and after the coating layer 42 is impregnated with paint or the like, the coating layer 42 is impregnated with paint or the like. Painting is done by rolling the surface and walls of the roof. As the first roller 40, a commercially available product that has been used conventionally can be used as it is.

The second arm 30 is provided so as to branch off from the first bent portion 21 of the first arm 20, and the second roller 50 is attached to and detached from the support shaft 31 at the tip thereof in a similar shape to the first arm 20. It is attached freely. Like the first roller 40, the second roller 50 is provided with a flexible coating layer 52 made of pile knitted fabric, pile woven fabric, or the like around a rotatable shaft center tube 51, and the coating layer 52 is provided with paint or the like. After soaking in, the surface and walls of the roof are rolled to paint. The length, outer diameter, or both of the second roller 50 is smaller than that of the first arm 20.

The second arm 30 is pivotally supported by a fastener 70 in the vicinity of the first bent portion 21 of the first arm 20, and rotates around the fastener 70 as shown in FIGS. 2 and 3. It is free. That is, as shown in FIG. 4, a metal shaft support plate 60 is welded in the vicinity of the first bent portion 21 of the first arm 20. Then, the root portion of the second arm 30 is pivotally supported in the shaft support hole 61 penetrating the shaft support plate 60 by a fastener (throw screw) 70, and the second arm 30 is used as an axis for the second. The arm 30 is rotatable.

The fastener 70 is composed of a thumbscrew, a fastening bolt, or the like. By loosening the fastener 70, the second arm 30 freely rotates with respect to the first arm 20, and when the fastener 70 is tightened, the second arm 30 The second arm 30 can be fixed at an arbitrary angle with respect to the one arm 20. As a result, the distance between the first roller 40 and the second roller 50 can be arbitrarily adjusted, so that workability is improved and painting work can be efficiently performed according to various conditions.

Then, by using the roller type coating tool 100 according to the present invention having such a configuration, the distance between the first roller 40 and the second roller 50 can be arbitrarily adjusted, so that workability is improved and various conditions can be met. The corresponding painting work can be performed efficiently. For example, when painting a slate roof, as shown in FIG. 5, the surface of the slate plate 80, which occupies most of the surface, can be efficiently painted by using a large-sized first roller 40. it can.

On the other hand, the stepped frontage portion 81 of the slate plate 80 and the narrow portion (not shown) such as the window frame can be painted evenly and cleanly by using the second roller 50 having a small size. it can. Further, when the second coating or the sealer is applied, the undercoating or the sealer is applied by the first roller 40, and the top coating or the main coating is applied by the second roller 50. As a result, it is not necessary to change the coating tool every time the work is performed, and the work efficiency is greatly improved.

Further, since the distance between the first roller 40 and the second roller 50 can be arbitrarily adjusted only by loosening the fastener 70, the optimum positional relationship can be obtained according to the painted portion and the conditions. Further, when storing or transporting, as shown in FIG. 6, if the second arm 30 is rotated so as to be parallel to the first arm 20, it will not be bulky.

Further, as shown in FIGS. 4 and 7, if the shaft support hole 61 of the shaft support plate 60 is formed into an elongated hole extending in the axial direction or the longitudinal direction of the first arm 20, the first roller 40 and the second roller 50 can be formed. The interval can be set more finely. Further, as shown in FIG. 8, two vertical holes 63 and 64 are continuously provided in the horizontally elongated holes 62 extending in the longitudinal direction of the first arm 20 so as to be orthogonal to the horizontally elongated holes 62 and the vertically elongated holes 63 and 64. If one of them is connected by a pair of fasteners 70 and 70, respectively, the second arm 30 can be attached more stably.

Note that FIG. 8A shows one fastener 70 fastened to the first vertical hole 63, has a small angle between the second arm 30 and the first arm 20, and the first roller 40 and the first. It is fixed so that the distance between the two rollers 50 and the roller 50 becomes narrow. On the other hand, FIG. 8B shows one fastener 70 fastened to the second vertical hole 64, has a large angle between the second arm 30 and the first arm 20, and the first roller 40 and the first. It is fixed so that the distance between the two rollers 50 and the roller 50 is wide.

Further, in addition to such a configuration, as shown in FIGS. 9 and 10, a splash prevention plate 90 may be attached in the middle of the first arm 20. The splash prevention plate 90 is made of a lightweight plate member 91 made of substantially fan-shaped aluminum or plastic, and is attached to the middle of the first arm 20 by a spring washer 92 on the root side thereof. Then, by moving the spring washer 92 portion, the splash prevention plate 90 can be moved back and forth along the first arm 20.

That is, as shown in FIG. 11, the spring washer 92 is composed of a pin 92a, a spring 92b, a washer 92c, and a nut 92d, and between the flange 91a on the plate member 91 side and the metal fitting 92e. It is attached in the middle of the first arm 20 by sandwiching and connecting the first arm 20. Then, since the force of pushing the pin 92a and holding the pin 92a is relaxed so as to contract the spring 92b, it becomes movable in the longitudinal direction of the first arm 20, and when the pin 92a is released, the pin 92a splashes at that position due to the conditioning force of the spring 92b. The structure is such that the prevention plate 90 is fixed.

If the splash prevention plate 90 is attached in the middle of the first arm 20 in this way, the paint such as paint scattered or dripping from the roller 40 or 50 when painting a high place such as the ceiling will be applied to the splash prevention plate 90. Because it is received by, it is possible to prevent inconveniences such as the paint sticking to the worker or getting into the eyes.
