Description

[Technical Field]

[0001] The present invention relates to a roller brush cleaning holder used when cleaning a roller brush by rotating it. [Background technology]

[0002] Conventionally, roller brushes for painting have been known in which the bristles are attached to the outside of a cylinder. The roller brush is rotatably attached to a handle (applicator) and is impregnated with paint before use. After use, the roller brush is squeezed by hand to squeeze out the paint and then washed with water or a solvent, but in many cases, paint remains.

[0003] For this reason, Patent Document 1 discloses a cleaning holder for cleaning roller brushes, in which wires are attached to a shaft in a basket shape and a stirring propeller is fixed to the tip of the shaft. By configuring the cleaning holder in this way, it is said that it becomes possible to stir the paint and clean (dehydrate) the roller brushes. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Publication No. 10-258243 Summary of the Invention [Problem to be solved by the invention]

[0005] However, the conventional cleaning holder described in Patent Document 1 is configured to hold the center of the roller brush with a cage-shaped wire, which causes problems such as unstable rotation when the roller brush is rotated using an electric drill (motor), making it impossible to clean, or causing the roller brush to fall off.

[0006] SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a roller brush cleaning holder that can stably hold and clean a roller brush. [Means for solving the problem]

[0007] In order to achieve the above-mentioned object, the roller brush cleaning holder of the present invention comprises a shaft body, a first insertion portion attached to a predetermined position on the shaft body, which has a plurality of elastically deformable claw portions and onto which the base end side of the roller brush is extrapolated, and a second insertion portion attached to the shaft body closer to the tip side than the first insertion portion, which has a plurality of elastically deformable claw portions and onto which the tip side of the roller brush is extrapolated. [Effects of the Invention]

[0008] As such, the roller brush cleaning holder of the present invention comprises a shaft body, a first insertion portion, and a second insertion portion, and the first insertion portion and the second insertion portion enable both ends of the roller brush to be stably held and cleaned.

DETAILED DESCRIPTION OF THE INVENTION

[0010] Hereinafter, embodiments of the present invention will be described with reference to the drawings. However, the components described in the following examples are merely examples and are not intended to limit the technical scope of the present invention to those components. In the following examples, Example 1 describes a roller brush cleaning holder for a regular roller (inner diameter 38 mm), and Example 2 describes a roller brush cleaning holder for a small roller (inner diameter 15-16 mm) or a medium roller (inner diameter 26-27 mm). [Example]

[0011] (composition) First, the overall configuration of a roller brush cleaning holder 1 for regular rollers will be described using Figure 1. As shown in Figure 1, the roller brush cleaning holder 1 comprises a shaft 10, a first insertion part 21 attached to a predetermined position on the shaft 10, the first insertion part 21 having a plurality of elastically deformable claws 211, ..., and onto which the base end side of the roller brush (R) is fitted, and a second insertion part 22 attached to the shaft 10 closer to the tip side than the first insertion part 21, the second insertion part 22 having a plurality of elastically deformable claws 221, ..., and onto which the tip side of the roller brush (R) is fitted.

[0012] That is, the roller brush cleaning holder 1 is configured by attaching a first insertion portion 21 and a second insertion portion 22 to the tip side of a cylindrical shaft 10 of a predetermined length. As will be described later, the roller brush R is held by being inserted outside the first insertion portion 21 and the second insertion portion 22. Then, when the cleaning holder 1 is rotated with an electric drill or the like while holding the roller brush R, the paint material is blown off by centrifugal force.

[0013] 2(a), the first insertion portion 21 is composed of a central cylindrical portion 210 and a plurality of (six in this case) claw portions 211, ... rising from the periphery of this cylindrical portion 210. The inner diameter of the cylindrical portion 210 is formed to be approximately the same as the outer shape of the shaft body 10.

[0014] The claws 211 extend from a flange-shaped expanded diameter portion on one side of the cylindrical portion 210, extending generally parallel to the axial direction of the cylindrical portion 210 or tilting slightly outward. The tip of each claw 211 is chamfered to make it easier to insert a roller brush (R).

[0015] First insertion portion 21 is inserted into shaft body 10 with the expanded diameter portion facing the tip end, in other words, with claw portion 211 extending from the tip end toward the base end. In this embodiment, first insertion portion 21 is configured so that its attachment position relative to shaft body 10 is adjustable, thereby making it possible to adjust the distance between first insertion portion 21 and second insertion portion 22. For example, shaft body 10 may be configured to have multiple attachment holes corresponding to multiple attachment positions and be connected with screws, or may be configured so that they can slide simply by friction.

[0016] 2(b), the second insertion portion 22 is substantially similar to the first insertion portion 21 and is composed of a central cylindrical portion 220 and a plurality of (six in this case) claw portions 221, ... rising from the periphery of this cylindrical portion 220. The inner diameter of the cylindrical portion 220 is formed to be substantially the same as the outer shape of the shaft body 10.

[0017] The second insertion part 22 is inserted into the shaft 10 with the expanded diameter part facing the base end, in other words with the claw part 221 extending from the base end towards the tip end. In this embodiment, one claw part 222 of the six claw parts 221 of the second insertion part 22 is longer by a predetermined length than the other claw parts 221, and further has a return structure 222a formed near the tip to prevent the roller brush (R) from falling off. Note that the one particularly long claw part 222 does not have to be present, and all the claw parts may be the same length.

[0018] The shaft 10 is a metal rod with a cylindrical cross section of a predetermined length, and has a connecting hole 10b near one end (near the tip) so that the second insertion portion 22 can be connected without spinning freely, and a hexagonal column portion 10a with a hexagonal cross section near the other end (near the base end) so that it can fit into the chuck on the tool side.

[0019] (action) Next, the operation of the roller brush cleaning holder 1 will be explained using Figures 4(a), (b), and 5. First, as shown in Figures 4(a) and (b), the roller brush cleaning holder 1 is designed to be able to extrapolate (attach) roller brushes R of a plurality of lengths. In other words, by changing the attachment position of the first insertion portion 21 relative to the shaft body 10 according to the axial length of the roller brush R, it is possible to accommodate roller brushes R of almost any length.

[0020] When in use, the roller brush cleaning holder 1 simply and securely holds the roller brush by fitting the hexagonal column portion 10a at the base end of the shaft 10 into the chuck c of the power drill D and tightening the hexagonal column portion 10a. Rotating the power drill D causes the paint impregnated in the roller brush R to fly outward by centrifugal force. At this time, because at least the second insertion portion 22 at the tip side is connected to the shaft 10, the second insertion portion 22 (and the first insertion portion 21) and the roller brush R do not spin freely while the shaft 10 is rotating. In particular, with the cleaning holder 1 of this embodiment, the roller brush R can be rotated stably because the first insertion portion 21 and the second insertion portion 22 hold the roller brush R near both ends.

[0021] (effect) Next, the effects achieved by the roller brush cleaning holder 1 of this embodiment will be listed and explained.

[0022] (1) As described above, the roller brush cleaning holder 1 comprises the shaft 10, a first insertion section 21 attached to a predetermined position on the shaft 10, the first insertion section 21 having a plurality of elastically deformable claws 211, ..., and onto which the base end of the roller brush (R) is fitted, and a second insertion section 22 attached to the shaft 10 closer to the tip than the first insertion section 21, the second insertion section 22 having a plurality of elastically deformable claws 221, ..., and onto which the tip end of the roller brush (R) is fitted. In this way, because the roller brush cleaning holder 1 comprises the shaft 10, the first insertion section 21, and the second insertion section 22, both ends of the roller brush (R) can be stably held and cleaned by the first insertion section 21 and the second insertion section 22.

[0023] (2) Furthermore, the first insertion portion 21 can be attached at an adjustable position relative to the shaft 10, and the distance between the first insertion portion 21 and the second insertion portion 22 can be adjusted, so that roller brushes (R) of various lengths can be attached and used for cleaning.

[0024] (3) Furthermore, some of the multiple claw portions 221, ... of the second insertion portion 22 have a return structure 222a formed near the tip to prevent the roller brush (R) from falling off, and the core of the roller brush (R) engages with the return structure 222a, thereby preventing the roller brush (R) from falling off.

[0025] (4) Furthermore, the base end of the shaft body 10 has a hexagonal column portion 10a formed with a hexagonal cross section so as to fit into the chuck on the tool side, so that it can be easily and reliably fitted and tightened to the chuck c of an electric drill D or the like.

[0026] (5) Furthermore, a connecting hole 10b for connecting the second insertion portion 22 is provided on the side of the tip of the shaft body 10 so that the second insertion portion 22 does not spin freely while the shaft body 10 is rotating, thereby preventing the second insertion portion 22 and the roller brush (R) from spinning freely during rotation. [Example]

[0027] 6 to 9, a cleaning holder 4 for roller brushes for small rollers or medium rollers, which is different from that of Example 1, will be described below. Note that the same reference numerals will be used to describe the same or equivalent parts as those described in Example 1.

[0028] (composition) As shown in Figure 6, the cleaning holder 4 of the roller brush in this embodiment is formed in a rod shape overall, and is integrally provided with a round bar-shaped small diameter portion 5 having an outer diameter approximately the same as the shaft diameter of the roller brush (R), and a round bar-shaped large diameter portion 6 having an outer diameter larger than that of the small diameter portion 5, and of these, a rotation transmission means 7 is arranged in the small diameter portion 5 to transmit rotation to the roller brush (R).

[0029] The large diameter portion 6 is formed in the shape of a round bar with an outer diameter (diameter) of, for example, 8 mm, and is connected to the small diameter portion 5 via a step portion. The large diameter portion 6 is, for example, about 300 mm long and is located on the base end side when in use. A hexagonal column portion 6a is formed at the base end of the large diameter portion 6 so as to fit into a chuck c on the tool side, similar to the shaft body 10 of Example 1.

[0030] The small diameter portion 5 is formed in the shape of a round bar with an outer diameter (diameter) of 6 mm, for example, and is connected to the large diameter portion 6 via a step portion. The small diameter portion 5 is, for example, 115 mm long and is located at the tip end when in use. A tapered portion 5a is formed at the tip end of the small diameter portion 5 to make it easier to insert the roller brush (R). In this embodiment, a rotation transmission means 7 is located in the small diameter portion 5 near the step portion between the small diameter portion 5 and the large diameter portion 6.

[0031] Specifically, the rotation transmission means 7 is configured as follows to transmit the rotation of the small diameter portion 5 to the roller brush (R). That is, as shown in Fig. 7, the rotation transmission means 7 is configured from a first washer 71 inserted into the small diameter portion 5, a spring 72 inserted into the small diameter portion 5 closer to the tip than the first washer 71, a second washer 73 inserted into the small diameter portion 5 closer to the tip than the spring 72, and a packing 74 inserted into the small diameter portion 5 closer to the tip than the second washer 73. That is, the rotation transmission means 7 is configured by inserting the first washer 71, spring 72, second washer 73, and packing 74 into the small diameter portion 5 in this order.

[0032] The first washer 71, spring 72, and second washer 73 have the function of taking up the reaction force from the step between the small diameter portion 5 and the large diameter portion 6 and pressing the gasket 74 toward the tip side (roller brush (R) side).

[0033] The packing 74 is formed, for example, from synthetic rubber in a disk or ring shape with a through-hole in the center. The inner diameter of the through-hole of the packing 74 is approximately the same as the outer diameter of the small diameter portion 5, so that it has the function of transmitting the rotation of the small diameter portion 5 to the roller brush (R). That is, the packing 74 rotates together with the small diameter portion 5 due to frictional force through the inner surface of the through-hole, and this rotation is transmitted to the roller brush (small roller) R by frictional force through the side surface.

[0034] (action) Next, the usage state and operation of the cleaning holder 4 of the roller brush of this embodiment will be explained using Figures 8 and 9. First, the small roller R will be explained. The small roller R is composed of an inner cylinder r1, an expanded space r3 inside the inner cylinder r1, a C-ring r2 placed in the space r3, and bristles r4 attached to the outside of the inner cylinder r1.

[0035] When in use, as shown in FIG. 8, the small-diameter portion 5 is inserted into the inner tube r1, and the tip of the small-diameter portion 5 is inserted into and fixed in the C-ring r2. At this time, the spring 72 is in a compressed state. In this state, the small-diameter portion 5 and the C-ring r2 are fixed, but the C-ring r2 is free within the space r3, allowing the inner tube r1 and bristles r4 to rotate relative to the C-ring r2 (and the small-diameter portion 5). Therefore, if the small-diameter portion 5 (the roller brush cleaning holder 4) is rotated in this state, the small-diameter portion 5 (and the C-ring r2) will rotate freely inside the small roller R. Therefore, in this embodiment, a packing 74 is used to transmit the rotation of the small-diameter portion 5 to the small roller R via the inner tube r1. In other words, since the packing 74 is made of rubber, it rotates together with the small-diameter portion 5, and the small roller R is rotated through this packing 74.

[0036] However, when actually rotated, the small roller R shifts downward due to the weight of the paint contained in the small roller R and the influence of vibrations caused by rotation (FIGS. 9(a)-(b)). In other words, the small roller R moves in a direction away from the packing 74. Therefore, in this embodiment, the packing 74 is pushed downward by the spring 72 to follow this movement (shift), so that the packing 74 is always in contact with the small roller R even after it shifts. After rotating for a few seconds, the paint is scattered and the small roller R becomes lighter (the inertial force becomes smaller), so the small roller R can continue to rotate even if the pressing force from the packing 74 weakens.

[0037] (effect) (6) As described above, the roller brush cleaning holder 4 of this embodiment integrally comprises a round bar-shaped small diameter portion 5 having an outer diameter substantially the same as the shaft diameter of the roller brush, and a round bar-shaped large diameter portion 6 having an outer diameter larger than that of the small diameter portion 5, and further comprises a rotation transmission means 7 that transmits the rotation of the small diameter portion 5 to the roller brush (R). Therefore, by rotating the roller brush cleaning holder 4, the roller brush (small roller) R rotates without spinning freely, and the paint can be blown off by centrifugal force to be cleaned and dried.

[0038] (7) Furthermore, the rotation transmission means 7 is composed of a first washer 71 inserted into the small diameter portion 5, a spring 72 inserted into the small diameter portion 5 closer to the tip than the first washer 71, a second washer 73 inserted into the small diameter portion 5 closer to the tip than the spring 72, and a packing 74 inserted into the small diameter portion 5 closer to the tip than the second washer 73. Therefore, even if the roller brush (small roller) R shifts downward during rotation, the rotation can be transmitted by frictional force while following the "shift."

[0039] (8) Furthermore, the base end of the large diameter portion 6 is provided with a hexagonal column portion 6a formed with a hexagonal cross section so as to fit into the chuck c on the tool side, thereby enabling easy and reliable fitting and tightening of the chuck c of an electric drill D or the like.

[0040] The other configurations and effects are substantially the same as those of the above embodiment, and therefore description thereof will be omitted.

[0041] Although the embodiments of the present invention have been described above in detail with reference to the drawings, the specific configuration is not limited to this embodiment, and design changes that do not deviate from the gist of the present invention are included in the present invention.
