The stirring blades 6 and 7 are formed in the same shape, and a plate having a width W1 and a length L1 is twisted at a substantially central portion in the longitudinal direction so that the tips 6b and 7b rotate in a predetermined direction (rotation). Direction). The stirring blades 6, 7 are provided with holes 6c, 7c provided in the base ends 6a, 7a.
Is inserted into the screw shaft 8 (or bolt) penetrated through the holes at the tip ends of both side walls 3a and 3b of the bracket 3, and nuts 9 and 10 are screwed into both ends of the screw shaft 8, respectively. 2 are rotatably mounted inside the side walls 3a and 3b in the directions indicated by arrows A and B in FIG. In addition,
On the screw shaft 8 between the base ends 6a, 7a of the stirring blades 6, 7,
Pipe 1 for restricting inward movement of stirring blades 7, 8
1 is inserted.

When the shaft 2 is in a substantially vertical state, the stirring blades 6 and 7 are in a non-expanded state with their tip portions 6b and 7b positioned at the lowermost ends due to their own weight. Maximum external dimensions W2 when viewed in (see FIG. 1)
Is set to be the minimum dimension. The maximum outer dimension W2 of the stirring blades 6, 7 is determined by the paint discharge port 13 formed at the corner of the upper surface 12a of the can 12 shown in FIG.
Is smaller (W2 <d), and the length L2 (see FIG. 1) of the shaft 2 is set to be larger than the height h of the can 12 by a predetermined dimension (L2 = h + α). Further, the shaft 2, the bracket 3, the stirring blades 6, 7 and the pipe 11 are formed of a stainless steel material in order to prevent corrosion caused by paint, thinner and the like.

Next, an example of a method of using the paint stirrer 1 will be described with reference to FIGS. 3 and 4, taking an example in which the paint can is a single can 12. First, the cap (not shown) attached to the paint outlet 13 on the upper surface 12a of the can 12 containing the paint 15 is removed, and the rotating tool engaging portion 2a of the shaft 2 is Chuck unit 14
Chuck with a. When the paint stirrer 1 is made vertical as shown by the solid line in FIG. 3, the stirring blades 6 and 7 are in a non-spreading state by their own weight. Insert into can 12.

At this time, since the maximum outer dimension W2 of the paint agitator 1 when the stirring blades 6 and 7 are not expanded is set smaller than the inner diameter d of the paint outlet 13, the stirring blades 6 and 7 are made smaller. It can be easily inserted into the paint outlet 13. When the stirring blades 6 and 7 of the paint stirrer 1 are inserted into the can 12 together with the bracket 3 and the tip of the shaft 2 for a predetermined distance, for example, the paint stirrer 1 is inclined in the direction of arrow C in FIG. The blades 6 and 7 are located substantially at the center of the can 12. Then, when the electric rotary tool 14 is turned on and operated in this state, the chuck portion 14a rotates in a predetermined direction,
By the rotation of the chuck portion 14a, the shaft 2, the bracket 3, and the stirring blades 6 and 7 are integrally rotated in the same direction (for example, the direction indicated by the arrow D).

When the stirring blades 6 and 7 rotate, the tip 6
Centrifugal force is applied to b and 7b, and the centrifugal force causes the stirring blade 6 to rotate and expand in the direction of arrow A as shown in FIG. 4, and the stirring blade 7 to rotate in the direction of arrow B and expand. Expand. With the spread of the stirring blades 6 and 7, the paint 1
At this time, the centrifugal force effectively acts on the tips 6b, 7b because the tips 6b, 7b are oriented substantially in the rotational direction due to the twisting of the stirring blades 6, 7 at this time. As a result, the stirring blades 6 and 7 are quickly spread, and the paint 15 is well stirred by the expanded front end portions 6b and 7b.

The stirring operation by the electric rotating tool 14 is
By appropriately changing the position of the stirring blades 6 and 7 on the plane and the position in the height direction in the single can 12, the paint 15 in the single can 12 is uniformly stirred in the entire area. When the stirring operation is completed, the rotation of the electric rotary tool 14 is stopped, the stirring blades 6 and 7 are returned to the non-spreading state by their own weight, and are taken out from the paint discharge port 13. The removed paint agitator 1 is immersed in a can (not shown) containing a liquid such as a thinner, for example, with the agitating blades 6, 7 and the bracket 3 to which the paint 15 has adhered, and by operating the electric rotary tool 14. Then, the stirring blades 6, 7 and the like rotate in the thinner, and the adhered paint 15 is reliably and easily removed, so that the paint 15 can be reused.

As described above, according to the paint stirrer 1 of the embodiment, the pair of stirring blades 6, 7 are rotatably mounted on the bracket 3 fixed to the tip of the shaft 2, and the stirring blades 6, 7 are attached. Since the centrifugal force causes rotation of the electric rotary tool 14 to expand the paint, the paint 15 in the can 12 can be stirred by the spread stirring blades 6 and 7 having a relatively large area.

In particular, since the stirring blades 6 and 7 are twisted and the tip portions 6b and 7b are substantially directed in the rotation direction, and the stirring is based on the mechanically stable rotation by the electric rotating tool 14, the stirring blades 6 and 7 are rotated. The centrifugal force effectively acts on the tip portions 6b, 7b of the nozzles 7, 7, so that the stirring blades 6, 7 are quickly expanded to have a large area for stirring, and the paint 15 can be well stirred. As a result, the state of the paint 15 in the can 12 can be made more uniform, and the coating quality can be improved.

Further, the paint 15 can be agitated by rotating the electric rotary tool 14 by engaging the chuck 14a of the electric rotary tool 14 with the rotary tool engaging portion 2a of the shaft 2, so that the paint 15 can be mechanically stirred. Agitation becomes possible,
The time required for the stirring operation can be reduced and the operation time can be reduced, the stirring efficiency can be improved, and the work efficiency of the coating operation at the coating site can be greatly improved.

Further, by bringing the paint agitator 1 into a vertical state, the stirring blades 6 and 7 are automatically set to a non-spreading state by their own weight, and the stirring blades 6 and 7 in the non-spreading state are also set. Of the paint outlet 1 of the can 12
Since the inner diameter d is set to be smaller than 3, the paint stirrer 1 can be easily used for a single can 12 having a small-diameter paint outlet 13.

Further, since the pair of stirring blades 6 and 7 can be rotatably mounted on the tip of the shaft 2 via the bracket 3, the paint stirring device 1 itself can be formed at low cost. At the same time, it is possible to obtain the paint stirrer 1 which is excellent in usability, for example, it can be formed light in weight and is easy to carry and store. Furthermore, since stainless steel is used for various parts, corrosion by the paint 15 or the like is prevented, and the work of removing the adhered paint 15 can be performed while rotating, so that reliable removal becomes possible. The paint stirrer 1 that can be used for a long time can be obtained.

In the above embodiment, the case in which the paint can is a single can 12 has been described as an example. However, the paint can according to the present invention is not limited to this. Of course, even a paint can can be used. In addition, the present invention is not limited to the case of mixing and stirring the paints contained in the paint can, but also the case of mixing and stirring a plurality of color paints in an appropriate can (container), the case of mixing and stirring a paint with a thinner or the like. Can be used. further,
The shapes and various dimensions of the stirring blades 6 and 7 and the bracket 3 in the above-described embodiment, the rotation structure for mounting the stirring blades 6 and 7 to the bracket 3 and the like are only examples, and do not depart from the gist of each invention according to the present invention. It goes without saying that various changes can be made.

[0024]

Since the paint is agitated while being applied and spread, the paint can be agitated by the spread stirring blade having a relatively large area, and for example, the paint can be substantially uniformly stirred in the entire area of the paint can. At the same time, the efficiency of stirring the paint can be improved.

According to the second aspect of the present invention, in addition to the effects of the first aspect of the present invention, a twist is applied to the stirring blades provided on both sides of the bracket. And the expanding blades can be quickly expanded, and because the expanding blades expand in opposite directions, the expanding area of the stirring blades can be made larger, for example, in a paint can. The efficiency of stirring the paint can be further improved.

According to the third aspect of the invention, in addition to the effects of the first or second aspect, the maximum outer dimension of the stirring blade when the stirring blade is not expanded is the inner diameter of the paint outlet of the paint can. Since it is set to be smaller, the stirring blade can be inserted into a paint can having a small-diameter paint outlet such as, for example, a single can, and the paint in the single can can be satisfactorily stirred.

According to the fourth aspect of the present invention, in addition to the effects of the first to third aspects, the rotary tool engaging portion is provided on the base end side of the shaft. The joint can be engaged with, for example, a chuck of an electric rotating tool to rotate the shaft, and mechanically perform the expansion and rotation of the stirring blade, further improving the stirring efficiency of the paint.
