　ところで、上述した一般的な塗装具では、塗装用ローラーを塗料に浸して塗料を補充するものであるため、その作業が繁雑であり作業者の負担となっていた。これに対して、例えば特許文献１に開示されているような、塗装用ローラーの内部に、塗料を貯留するための貯留部材を設けた塗装具が提案されている。この特許文献１に開示された塗装具では、被塗装面を塗装する際、被塗装面に塗装用ローラーを押し付けると、貯留部材に保持されている塗料が押し出され、塗料供給流路を経由して塗装部材へ供給されるため、塗装用ローラーへの塗料の供給回数を減らすことができる。 By the way, in the above-mentioned general coating tool, the coating roller is dipped in the coating material to replenish the coating material, so the work is complicated and burdens the operator. On the other hand, a coating tool has been proposed, for example, as disclosed in Patent Document 1, in which a storage member for storing the coating material is provided inside the coating roller. In the coating tool disclosed in Patent Document 1, when the surface to be coated is coated with the coating roller, when the coating roller is pressed against the surface to be coated, the coating material held in the storage member is extruded and passes through the coating material supply flow path. Since it is supplied to the coating member as a coating material, the number of times of supplying the coating material to the coating roller can be reduced.

　しかしながら、上述した特許文献１に開示された塗装具では、塗装用ローラーの全長にわたって塗装供給流路が形成されており、塗料供給流路の全体から一気に塗料が滲出する構成であることから、塗装の際に塗装用ローラーが傾斜されると、下になった側に塗料が集まってしまうという問題があった。このため塗装用ローラーの使用状態によっては塗装にムラが生じる可能性があった。 However, in the coating tool disclosed in Patent Document 1 described above, the coating supply passage is formed over the entire length of the coating roller, and the coating is squeezed out from the entire coating supply passage at once, so that the coating is performed.

And an urging means for pressing the outer cylindrical portion against the outer peripheral surface of the coating roller.
　また、本発明は、上記塗装具を用いた塗装方法であって、内筒部に塗料を充填し、内筒部内の塗料を、内側スリットを通じて外方へ吐出させ、内側スリットを通じて吐出された塗料を、外筒部の外側スリットを通じて塗装用ローラーに含浸させて、塗装用ローラーを被塗装面に回転接触させて塗装することを特徴とする。 Further, the present invention is a coating method using the above-mentioned coating tool, in which the inner cylinder portion is filled with the paint, the paint in the inner cylinder portion is discharged outward through the inner slit, and the paint discharged through the inner slit.

The handle portion 2 is a portion that can be gripped by the operator's hand, and has various shapes that are easy to grip, in addition to the cylindrical shape, and may have irregularities to prevent slipping.
　このハンドル部２の先端には鍵形状に屈曲されたアーム２１が接続されている。このアーム２１は、内筒部３に連結され、内筒部３を介して塗装用ローラー４を回転自在に支持する把持部材である。本実施形態においてこのアーム２１は、内部に塗料が流通する流路が形成されたパイプ状の部材で構成され、内筒部３はこのアーム２１先端の直線部分を軸として軸支されているとともに、図４に示すように、このアーム２１内部の流路の内筒部３内に位置する先端部分が、塗料が充填される貯留部２１ａとしての役割を果たしている。また、このアーム２１は、図３に示すように、その後端の直線部分が、先端の直線部分と直交するように鍵形状に屈曲されており、ハンドル部２の先端に連結されている。ハンドル部２の後端部分には塗料供給手段６からのホース６１が挿入され、ハンドル部２内部においてアーム２１の後端部分に水密状態でホース６１の先端が接続されている。 An arm 21 bent into a key shape is connected to the tip of the handle 2. The arm 21 is a gripping member that is connected to the inner tubular portion 3 and rotatably supports the coating roller 4 via the inner tubular portion 3. In the present embodiment, the arm 21 is composed of a pipe-shaped member in which a flow path through which the paint flows is formed, and the inner cylindrical portion 3 is axially supported with the straight portion of the tip of the arm 21 as an axis. As shown in FIG. 4, the tip portion of the flow path inside the arm 21 located inside the inner cylindrical portion 3 serves as a storage portion 21a filled with the coating material. Further, as shown in FIG. 3, the arm 21 is bent in a key shape so that the linear portion at the rear end thereof is orthogonal to the linear portion at the distal end, and is connected to the distal end of the handle portion 2. A hose 61 from the paint supply means 6 is inserted into the rear end portion of the handle portion 2, and the tip end of the hose 61 is connected to the rear end portion of the arm 21 inside the handle portion 2 in a watertight state.
　上記内筒部３は、塗料が充填される貯留部として機能する円筒状の内部中空部材であり、上述したようにアーム２１先端の直線部分に軸支されるとともに、アーム２１先端に対して回転しないように固定されている。また、図４に示すように、内筒部３は、アーム２１内部の流路の内筒部３内に位置する先端部分が、貯留部２１ａとしての役割を果たしており、アーム２１内の流路を通じて内筒部３内部の貯留部２１ａに塗料が充填されるようになっている。一方、図５に示すように、内筒部３の側面外表部には、軸方向に沿って延設され、内筒部３を内外に連通させる内側スリット３１が複数平行に形成されている。本実施形態では、この内側スリット３１は直線状に形成されている。 The inner cylindrical portion 3 is a cylindrical inner hollow member that functions as a reservoir filled with paint, is axially supported by the linear portion of the tip of the arm 21 and rotates with respect to the tip of the arm 21 as described above. It is fixed not to. Further, as shown in FIG. 4, in the inner tube portion 3, the tip portion of the flow path inside the arm 21 located inside the inner tube portion 3 serves as the storage portion 21 a, and the flow path inside the arm 21 is The coating material is filled into the storage portion 21a inside the inner cylindrical portion 3 through. On the other hand, as shown in FIG. 5, a plurality of inner slits 31 extending in the axial direction and communicating the inner cylinder 3 with the inside and the outside are formed in parallel on the outer surface of the side surface of the inner cylinder 3. In this embodiment, the inner slit 31 is formed in a linear shape.
　さらに、本実施形態における内筒部３内には、内筒部３側面外表部の各内側スリット３１とアーム２１内の貯留部２１ａ部分とを連通させて塗料を内側スリット３１に供給するための流路３１ａが、内筒部３の径方向に放射状に配置されるようにそれぞれ形成されている。この流路３１ａは、各内側スリット３１と貯留部２１ａ部分とを連通させる構成であれば管状の部材であってもよく、単にスリットであってもよい。 Further, in the inner cylinder portion 3 in the present embodiment, the inner slits 31 of the outer surface portion of the side surface of the inner cylinder portion 3 are communicated with the storage portion 21a portion in the arm 21 to supply the paint to the inner slit 31. The flow paths 31a are formed so as to be arranged radially in the radial direction of the inner tubular portion 3. The flow path 31a may be a tubular member as long as it is configured to communicate each inner slit 31 with the storage portion 21a portion, or may be simply a slit.
　なお、この各内側スリット３１と貯留部２１ａ部分とを連通させる構成は省略することができ、内筒部３内部全体を中空として、内筒部３内全体を貯留部として機能させてもよく、内筒部３内全体に塗料を充填させて、直接内側スリット３１から塗料を滲出させるようにしてもよい。このとき、内筒部３内にはスポンジやフエルト、不織布等の塗料が含浸されて塗料を保持する部材を充填してもよい。また、この場合には、アーム２１の貯留部２１ａと内筒部３の外表面との一体性を確保するとともに、貯留部２１ａ外表面と内筒部３の内表面との間隔を保持するために、流路３１ａに相当する部位に、内筒部３の径方向に向けて放射状に突っ張るようなセパレータを設けてもよい。 In addition, the structure which connects each inner slit 31 and the storage part 21a part can be abbreviate | omitted, and the whole inner cylinder part 3 inside may be made hollow, and the whole inner cylinder part 3 may function as a storage part, It is also possible to fill the entire inside of the inner cylindrical portion 3 with paint and allow the paint to exude directly from the inner slit 31. At this time, the inner cylindrical portion 3 may be filled with a member that holds the paint by being impregnated with the paint such as sponge, felt, and non-woven fabric. In addition, in this case, in order to secure the integrity of the storage portion 21a of the arm 21 and the outer surface of the inner tubular portion 3, the distance between the outer surface of the storage portion 21a and the inner surface of the inner tubular portion 3 is maintained. In addition, a separator that radially extends in the radial direction of the inner cylindrical portion 3 may be provided at a portion corresponding to the flow path 31a.
　内筒部３外周には外筒部５が嵌挿されている。この外筒部５は、内筒部３の外周面に沿って摺動回転される筒状の部材であり、塗装用ローラー４が外方に嵌挿される。この外筒部５の側面において、軸方向に沿って延設され外筒部５を内外に連通させる外側スリット５１が形成されている。この外側スリット５１は、内側スリット３１と交差する交差部分ＣＰが形成されるような形状をなした細長の穴であり、本実施形態では螺旋状に複数本平行に形成されている。 An outer cylinder part 5 is fitted around the outer circumference of the inner cylinder part 3. The outer tubular portion 5 is a tubular member that is slidably rotated along the outer peripheral surface of the inner tubular portion 3, and the coating roller 4 is fitted and inserted outward. On the side surface of the outer tubular portion 5, an outer slit 51 extending along the axial direction and connecting the outer tubular portion 5 to the inside and the outside is formed. The outer slit 51 is an elongated hole having a shape in which an intersecting portion CP intersecting with the inner slit 31 is formed, and in the present embodiment, a plurality of spiral slits are formed in parallel.
　塗装用ローラー４は、例えば、スポンジや不織布などの海綿状の素材で筒状に形成された部材であり、外筒部５の外周面に嵌挿される。また、塗装用ローラー４の形態は用途に応じて種々変更が可能であり、例えば、外筒部５の外表面から径方向外方に向けて突設された多数の毛材で筒状に形成することもできる。 The coating roller 4 is, for example, a member formed in a tubular shape from a sponge-like material such as sponge or non-woven fabric, and is fitted and inserted into the outer peripheral surface of the outer tubular portion 5. Further, the form of the coating roller 4 can be variously changed according to the application, and for example, the coating roller 4 is formed into a tubular shape with a large number of bristle materials protruding radially outward from the outer surface of the outer tubular portion 5. You can also do it.
（塗装方法）
　以上説明した塗装具を使用して、本発明の塗装方法を実施することができる。図６は、塗装具１の使用状態を示す説明図である。 (Painting method)
The coating method of the present invention can be implemented using the coating tool described above. FIG. 6 is an explanatory view showing a usage state of the coating tool 1.
　まず、塗料供給手段６からホース６１を通じて塗料を内筒部３内に塗料を充填する。これによって、内筒部３内の塗料が、内側スリット３１を通じて外方へ吐出され、その吐出された塗料を、外筒部５の外側スリット５１との交差部分ＣＰを通じて塗装用ローラー４に含浸させる。そして、この状態で塗装用ローラー４を被塗装面に回転接触させて塗装する。 First, the paint is filled from the paint supply means 6 through the hose 61 into the inner cylindrical portion 3. As a result, the coating material in the inner cylindrical portion 3 is discharged outward through the inner slit 31, and the discharged coating material is impregnated into the coating roller 4 through the intersection CP with the outer slit 51 of the outer cylindrical portion 5. .. Then, in this state, the coating roller 4 is rotated and brought into contact with the surface to be coated for coating.
　このように塗装用ローラー４が回転接触されることにより、塗装用ローラー４の回転に伴って外筒部５が回転される。内筒部３はアーム２１に固定されているため回転しないことから、外筒部５が内筒部３の外周面に沿って相対的に回転移動する。外筒部５が内筒部３に対して相対的に回転することにより、図６（ａ）～（ｃ）に示すように、外側スリット５１と内側スリット３１の交差部分ＣＰが塗装用ローラー４の軸方向に順次移動することとなる。内筒部３内の塗料は交差部分ＣＰを通じて塗装用ローラー４に滲出するため、塗装用ローラー４の回転に伴って交差部分ＣＰを常に軸方向に移動させることによって、塗料を塗装用ローラー４の全長にわたって含浸させることができる。 By rotating the coating roller 4 in this manner, the outer cylinder 5 is rotated as the coating roller 4 rotates. Since the inner tubular portion 3 is fixed to the arm 21 and does not rotate, the outer tubular portion 5 relatively rotates along the outer peripheral surface of the inner tubular portion 3. By rotating the outer cylinder portion 5 relative to the inner cylinder portion 3, as shown in FIGS. 6 (a) to 6 (c), the intersection CP of the outer slit 51 and the inner slit 31 is at the coating roller 4. It will be moved sequentially in the axial direction of. Since the coating material in the inner tube portion 3 seeps out to the coating roller 4 through the intersection portion CP, the coating material of the coating roller 4 is always moved by axially moving the intersection portion CP as the coating roller 4 rotates. It can be impregnated over its entire length.
（変更例）
　なお、以上説明した実施形態は、本発明の一例である。このため、本発明は上述した実施形態に限定されることなく、本発明に係る技術的思想を逸脱しない範囲であれば、設計等に応じて種々の変更が可能である。 (Example of change)
The embodiment described above is an example of the present invention. Therefore, the present invention is not limited to the above-described embodiments, and various modifications can be made according to the design and the like as long as they do not depart from the technical idea of the present invention.
　例えば、上述した実施形態では、内側スリット３１を直線状とし、外側スリット５１を螺旋状としたが、図９及び図１０に示すように、内側スリット３１を螺旋状とし、外側スリットを直線状としてもよい。このように内側スリット３１を螺旋状とし外側スリットを直線状とした場合、消耗品となる塗装用ローラー４側に取付けられる外筒部５を簡単な構造とすることができ、アーム２１及び内筒部３からなる本体部分と別売りにするときなどに、製造コストを抑えて消耗品の低廉化を図ることができる。 For example, in the above-described embodiment, the inner slit 31 has a linear shape and the outer slit 51 has a spiral shape. However, as shown in FIGS. 9 and 10, the inner slit 31 has a spiral shape and the outer slit has a linear shape. Good. When the inner slit 31 has a spiral shape and the outer slit has a straight shape as described above, the outer cylinder portion 5 attached to the side of the coating roller 4 which is a consumable item can have a simple structure, and the arm 21 and the inner cylinder can be structured. When it is sold separately from the main body portion including the portion 3, the manufacturing cost can be suppressed and the cost of consumables can be reduced.
　なお、内側スリット３１又は外側スリット５１は、点状の交差部分ＣＰが形成されるような形状をなしていればどのような形状であってもよく、例えば螺旋状に代えて波形、サインカーブ形・コサインカーブ形とすることもできる。また、これらの各スリットは各筒体に複数設けてもよく、単数だけ設けてもよい。 The inner slit 31 or the outer slit 51 may have any shape as long as it has a shape in which a dot-shaped intersecting portion CP is formed.

（塗装方法）
　以上説明した塗装具を使用して、本発明の塗装方法を実施することができる。
　まず、塗料供給手段６からホース６１を通じて塗料を内筒部７３内に塗料を充填する。これによって、内筒部７３内の塗料が、内側スリット７３ａを通じて外方へ吐出され、その吐出された塗料を、外筒部７４の外側スリット７４ａとの交差部分を通じて外方へ滲出させる。そして、この状態で外筒部７４を塗装用ローラー４に接触させて、滲出された塗料を外筒部７４の外周面側から塗装用ローラー４の表面側へと転移させることによって塗装用ローラー４に塗料を含浸させ、塗装用ローラー４を被塗装面に回転接触させて塗装する。 (Painting method)
The coating method of the present invention can be implemented using the coating tool described above.
First, the inner cylinder portion 73 is filled with the paint from the paint supply means 6 through the hose 61. As a result, the paint in the inner cylinder portion 73 is discharged outward through the inner slit 73a, and the discharged paint is exuded outward through the intersection of the outer cylinder portion 74 and the outer slit 74a. Then, in this state, the outer cylinder portion 74 is brought into contact with the coating roller 4, and the exuded paint is transferred from the outer peripheral surface side of the outer cylinder portion 74 to the front surface side of the coating roller 4 to thereby transfer the coating roller 4 to the coating roller 4. The coating roller 4 is impregnated with the coating material, and the coating roller 4 is rotated and brought into contact with the surface to be coated.
　そして、このように外筒部７４が塗装用ローラー４に押圧されて接触されることにより、塗装用ローラー４の回転に伴って外筒部７４が回転される。内筒部７３はアーム７２に固定されているため回転しないことから、外筒部７４が内筒部７３の外周面に沿って相対的に回転移動する。外筒部７４が内筒部７３に対して相対的に回転することにより、図６（ａ）～（ｃ）によって説明した原理と同様の原理によって、外側スリット７４ａと内側スリット７３ａの交差部分が塗装用ローラー４の軸方向に順次移動することとなる。内筒部７３内の塗料は交差部分を通じて外筒部７４の外表面に滲出して塗装用ローラー４側に転移されるため、塗装用ローラー４の回転に伴って交差部分が常に軸方向に移動されることとなり、塗料を塗装用ローラー４の全長にわたって含浸させることができる。 Then, the outer cylinder portion 74 is pressed and brought into contact with the coating roller 4 in this manner, whereby the outer cylinder portion 74 is rotated along with the rotation of the coating roller 4. Since the inner tubular portion 73 is fixed to the arm 72 and does not rotate, the outer tubular portion 74 relatively rotates along the outer peripheral surface of the inner tubular portion 73. By rotating the outer cylindrical portion 74 relative to the inner cylindrical portion 73, the intersection of the outer slit 74a and the inner slit 73a is caused by the same principle as that described with reference to FIGS. 6 (a) to 6 (c). The coating roller 4 is sequentially moved in the axial direction. The paint in the inner cylinder portion 73 exudes to the outer surface of the outer cylinder portion 74 through the intersection and is transferred to the coating roller 4 side, so that the intersection always moves in the axial direction as the coating roller 4 rotates. As a result, the coating material can be impregnated over the entire length of the coating roller 4.

However, as shown in FIGS. 14 to 16, the inner slit 73a has a linear shape. The outer slit may have a spiral shape. The inner slit 73a or the outer slit 74a may have any shape as long as it has a shape in which dot-shaped intersecting portions are formed. For example, instead of spiral shape, corrugated shape, sine curve shape, It can also have a cosine curve shape. Further, a plurality of each of these slits may be provided in each cylindrical body, or only a single slit may be provided.
