[0010] [Figure 1] FIG. 2 is a perspective view showing an overview of the wringer. [Diagram 2] This is an exploded view of the workpiece that serves as the original form of the squeezing tool. [Diagram 3] FIG. 13 is a side view showing an overview of the wringer (modified example). DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] As shown in FIG. 1, the wringing tool 2 is for wringing a coating roller R, and includes a wringing mechanism 10 and a handle 20 having the wringing mechanism 10 formed at its tip.

[0012] The painting roller R includes a roller shaft RX, a cylindrical core RC that is rotatable about the roller shaft RX, and a cylindrical roller body RN attached to the core RC. The core RC and the roller body RN are coaxial. The roller body RN is made of a material that can absorb paint, such as hair or sponge. When the roller body RN is immersed in paint, the paint soaks into the roller body RN. By pressing the roller body RN against the area to be painted, the paint that has soaked into the roller body RN is applied to the area to be painted.

[0013] The throttle mechanism 10 includes a tubular member 11. An opening 11A at one end of the tubular member 11 has a diameter larger than the outer diameter of the roller body RN. Therefore, the roller body RN can pass through the opening 11A at one end of the tubular member 11 in the axial direction. An opening 11B at the other end of the tubular member 11 has a diameter larger than the outer diameter of the core RC and smaller than the outer diameter of the roller body RN. Therefore, the core RC can pass through the opening 11B at the other end of the tubular member 11 in the axial direction and the roller body RN comes into contact with the opening 11B at the other end of the tubular member 11. It is preferable that the diameter of the opening of the tubular member 11 is smaller from the one end of the tubular member 11 to the other end of the tubular member 11. It is preferable that the tubular member 11 is tapered.

[0014] The cylindrical member 11 may have a notch 11K formed therein. The notch 11K is preferably configured to allow the roller shaft RX to pass therethrough. The notch 11K is preferably C-shaped when viewed from the axial direction X of the cylindrical member 11. The notch 11K preferably extends in the axial direction X of the cylindrical member 11.

[0015] The handle 20 is preferably provided on one end side of the tubular member 11. The handle 20 extends in a direction intersecting at an acute angle with the radial direction Y of the tubular member 11. Alternatively, the handle 20 may extend in the axial direction X of the tubular member 11.

[0016] Next, a method of using the wringer 2 will be described.

[0017] As shown in Fig. 1, the handle RE of the painting roller R is held so that the axial direction of the roller body RN is vertical. Next, the wringer 2 is held so that the axial direction X of the tubular member 11 is coaxial with the axial direction of the roller body RN. At this time, the opening 11B on the other end side of the tubular member 11 faces the roller body RN of the painting roller R.

[0018] When the cylindrical member 11 is brought close to the painting roller R, a squeezing step is performed in which one end side of the roller body RN is brought into contact with the other end opening 11B of the cylindrical member 11. In this manner, the other end opening 11B is pressed against the roller body RN of the painting roller R, so that the roller body RN containing the paint can be squeezed.

[0019] When the other end opening 11B advances to the middle of the roller body RN, the diameter of the cylindrical member 11 becomes larger at one end of the roller body RN, so the pressing is released and the roller body RN of the painting roller R tries to return to its original shape by its own restoring force. At this time, since the roller body RN is inside the cylindrical member 11, the cylindrical member 11 blocks the paint that would splash when the roller body RN returns to its original shape, so the paint does not splash around the cylindrical member 11.

[0020] Next, a method for manufacturing the wringer 2 will be described.

[0021] 2, the work 30 is a component for forming the wringing tool 2, and is formed from a plate-shaped member. The work 30 includes a handle member 31, and a left member 33 and a right member 34 extending left and right at the tip of the handle member 31. The work 30 is preferably made of metal.

[0022] Handle member 31 extends straight from the base end (upper end in the figure) to the tip end (lower end in the figure). Left member 33 and right member 34 each extend left and right from the tip of handle member 31. The tip of left member 33 extends toward the opposite side to the base end of handle member 31. The tip of right member 34 extends toward the opposite side to the base end of handle member 31. It is preferable that left member 33 and right member 34 are curved. Then, handle member 31 extends from the convex portion of the curved portion (upper part in the figure).

[0023] When the left member 33 and the right member 34 are curved so that the tip of the left member 33 and the tip of the right member 34 approach each other (toward the viewer in the drawing), they form a C-shape when viewed from above the drawing. In this manner, the left member 33 and the right member 34 become the tubular member 11, and the handle member 31 becomes the handle 20, and the squeezing tool 2 (FIG. 2) can be manufactured from the workpiece 30. Because the left member 33 and the right member 34 are curved, a tapered tubular member 11 can be formed.

[0024] Since the workpiece 30 is formed from a plate-shaped member, the drawing tool can be manufactured only through a bending process, which makes it possible to reduce manufacturing costs.

[0025] In the above embodiment, a squeezing step was performed in which one end side of the roller body RN was brought into contact with the other end side opening 11B of the tubular member 11, but the present invention is not limited to this, and one end side of the roller body RN may be introduced from the one end side opening 11A of the tubular member 11.

[0026] In the above embodiment, the notch 11K extends in the axial direction X of the tubular member 11. However, the present invention is not limited to this.

[0027] In the above embodiment, the handle 20 extends in a direction intersecting at an acute angle with the radial direction Y of the tubular member 11, but the present invention is not limited to this. For example, as shown in Fig. 3, the handle 20 may include a base 22 extending in the radial direction Y of the tubular member 11, and a handle main body 21 extending from the tip of the base 22 in a direction intersecting at an acute angle with the radial direction Y. By providing the base 22, paint or the like adhering to the roller body RN is less likely to adhere to the handle main body 21.

[0028] A magnet 25 may also be provided on the handle 20. The magnet 25 is preferably provided on the side of the handle 20 opposite the tubular member 11. This allows the wringer 2 to be fixed to an iron can, an iron bucket, or the like. Therefore, the roller body RN containing the paint can be wringed out simply by moving the painting roller R held in one hand.

[0029] In the above embodiment, the handle 20 extends from one end side of the tubular member 11, but the present invention is not limited to this. The handle 20 may extend from the other end side of the tubular member 11.

[0030] Incidentally, the present invention is not limited to the above-described embodiment, and it goes without saying that various modifications can be made without departing from the spirit and scope of the present invention. [Explanation of symbols]
