Description

この発明は、塗装用ローラのハンドルに長尺柄を連結する連結機構に関する。 The present invention relates to a connection mechanism for connecting an elongated handle to a handle of a painting roller.

長尺柄を連結する塗装用ローラとして特許文献1に記載されたものが、従来から知られている。この従来の連結機構を示したのが本願に添付した図6~8である。ただし、図6に示した塗装用ローラRはこの発明の連結機構でも用いるものである。
上記塗装用ローラRは、図6~8に示すように、ハンドル1にワイヤー2を固定するとともに、このワイヤー2にローラ部材3を回転自在に設けている。
2. Description of the Related Art A coating roller that connects elongated handles and is described in Patent Document 1 is conventionally known. This conventional connection mechanism is shown in FIGS. 6 to 8 attached to this application. However, the coating roller R shown in FIG. 6 is also used in the connection mechanism of the present invention.
As shown in FIGS. 6 to 8, the coating roller R has a wire 2 fixed to a handle 1, and a roller member 3 rotatably provided on the wire 2.

このようにした塗装用ローラRは、原則的には、ハンドル1を直接握って、塗料を含めたローラ部材3を目的の面に転がして使用するものである。したがって、高所の塗装作業では、作業者がはしごや脚立に上って塗装作業をする。 In principle, the coating roller R thus constructed is used by directly gripping the handle 1 and rolling the roller member 3 containing the paint onto the target surface. Therefore, when painting at high places, workers climb up ladders or stepladders to perform the painting work.

しかし、天井のようにほぼ水平な広い塗装面の場合には、脚立の位置を何回も移動させなければならないし、その都度、脚立の上り下りをしなければならない。そのために、作業効率が著しく悪くなるという問題があった。
また、床面を塗装するときには、体をかがめなければならないので、その作業姿勢に無理が生じ、長時間の連続作業ができなくなるという問題があった。
However, in the case of a large painted surface that is almost horizontal, such as a ceiling, the position of the stepladder must be moved many times, and the stepladder must be climbed up and down each time. As a result, there was a problem in that work efficiency deteriorated significantly.
Furthermore, when painting a floor surface, the worker must bend down, which creates an awkward working posture, making it impossible to work continuously for a long time.

そこで、ハンドル1とは別に、図7に示す長尺柄4を備えるとともに、ハンドル1には雌ネジ部5を形成し、長尺柄4の先端には雌ネジ部5とねじ結合する雄ネジ部6を形成し、天井や床面を塗装するときには、図8に示すようにハンドル1に長尺柄4を連結できるようにしている。 Therefore, in addition to the handle 1, a long handle 4 shown in FIG. When forming the section 6 and painting the ceiling or floor surface, the elongated handle 4 can be connected to the handle 1 as shown in FIG. 8.

上記のように長尺柄4を連結した塗装用ローラRで天井面を塗装するときには、ローラ部材3に含まれた塗料が長尺柄4の方に流れてくる。この状態でローラ部材3を再び塗料容器につけようとすると、ローラ部材3を下に、長尺柄4を上にと、その高さ方向を逆向きにしなければならない。このように高さ方向を逆にすると、長尺柄4に付着していた塗料が逆流して雌ネジ部5にしみこんでいく。
また、塗装面積が大きくなれば、ローラ部材3と長尺柄4の高さ方向を逆向きにする回数も多くなるので、その分、長尺柄4に付着した塗料が雌ネジ部5にしみこんでいく量も多くなる。
When painting a ceiling surface with the painting roller R connected to the elongated handle 4 as described above, the paint contained in the roller member 3 flows toward the elongated handle 4. If the roller member 3 is to be applied to the paint container again in this state, the height direction must be reversed, with the roller member 3 facing down and the elongated handle 4 facing upward. When the height direction is reversed in this manner, the paint adhering to the elongated handle 4 flows backward and soaks into the female threaded portion 5.
Furthermore, as the coating area increases, the number of times the roller member 3 and the elongated handle 4 are turned in opposite height directions increases, so that the paint adhering to the elongated handle 4 soaks into the female threaded part 5. The amount you will need will also increase.

特許第4162937号公報Patent No. 4162937

上記のようにした従来の長尺柄連結機構では、ハンドル1と長尺柄4とをねじ結合しているので、それらのねじの部分に塗料がしみ込んで固まってしまうと、ねじの部分が相対回転できなくなり、結局は、ハンドル1と長尺柄4とを分離できなくなってしまう。 In the conventional long handle connection mechanism as described above, the handle 1 and the long handle 4 are connected by screws, so if the paint soaks into the threaded parts and hardens, the threaded parts will become relative to each other. It becomes impossible to rotate, and eventually the handle 1 and the elongated handle 4 cannot be separated.

特に、長尺柄の直径はそれほど大きくはないので、それを回そうとしても大きなトルクが得られない。このような条件の中で、ハンドル1と長尺柄4とのねじ結合部分で塗料が固まってしまうと、手ではそれらを相対回転させられなくなる。しかも、長尺柄4に塗料が付着していると、その塗料のぬめりなどで手が滑ってしまい、ねじ結合部分の相対回転がますます難しくなる。 In particular, since the diameter of the long handle is not very large, it is not possible to obtain a large torque even if you try to turn it. Under such conditions, if the paint hardens at the threaded joint between the handle 1 and the elongated handle 4, it becomes impossible to rotate them relative to each other by hand. Furthermore, if paint adheres to the long handle 4, the slime of the paint may cause the hand to slip, making relative rotation of the threaded joints increasingly difficult.

もし、ねじ結合部分を相対回転できなければ、その結合部分を少し洗浄液に浸しておき、結合部分の塗料を溶かすなどしなければならない。しかし、作業途中で洗浄液に浸すようなことをすれば、その作業効率が極端に悪くなる。 If the threaded joint cannot be rotated relative to each other, the joint must be immersed in a cleaning solution to dissolve the paint on the joint. However, if the work is soaked in cleaning liquid during the work, the work efficiency will be extremely poor.

一方、強い力でハンドル1を長尺柄4から外そうとすれば、ローラ部材3が不用意に大きく回されたり振れたりしてそこに含まれている塗料が飛散し、せっかくの塗装面を台無しにしたり、他の壁面などを汚したりするなどの問題が発生する。 On the other hand, if you try to remove the handle 1 from the long handle 4 with strong force, the roller member 3 will be carelessly turned or shaken, causing the paint contained therein to scatter and damaging the painted surface. Problems may occur such as ruining the wall or staining other walls.

また、塗装現場によっては、ハンドル1と長尺柄4との連結もしくは分離を何回も繰り返す場合がある。このような場合には、それらをスムーズに連結したり分離したりできなければ、作業効率が落ちてしまうという問題も発生する。 Further, depending on the painting site, the handle 1 and the elongated handle 4 may be connected or separated many times. In such a case, if they cannot be smoothly connected or separated, a problem arises in that work efficiency decreases.

この発明の目的は、ハンドルと長尺柄とを、スムーズに連結したり分離したりできる塗装用ローラの長尺柄連結機構を提供することである。 An object of the present invention is to provide a long handle connection mechanism for a painting roller that can smoothly connect and separate the handle and the long handle.

第1の発明は、連結部材の一方の端部に長尺柄を連続させる構成にしている。なお、長尺柄と連結部材とは、それらが連続する構成であれば、連結部材と長尺柄とを一体にしてもよいし、それらを別部材にしてもよい。 The first invention has a structure in which the elongated handle is continuous to one end of the connecting member. In addition, as long as the long handle and the connecting member are continuous, the connecting member and the long handle may be integrated or may be separate members.

また、上記連結部材とこの連結部材に対して着脱可能にした継ぎ手部材とのいずれか一方に挿入穴部が形成され、いずれか他方に軸部が形成されているが、それらは相対的であって、連結部材に挿入穴部が形成されれば継ぎ手部材にはその挿入穴部に挿入される軸部が形成され、連結部材に軸部が形成されれば継ぎ手部材に挿入穴部が形成される。 Further, an insertion hole is formed in either one of the connecting member and a joint member that is detachably attached to the connecting member, and a shaft is formed in the other, but these are relative. Therefore, if an insertion hole is formed in the connecting member, a shaft portion to be inserted into the insertion hole is formed in the joint member, and if a shaft portion is formed in the connecting member, an insertion hole is formed in the joint member. Ru.

そして、上記連結部材あるいは継ぎ手部材のいずれか一方に、挿入穴部に挿入された軸部が抜けるのを防止するストッパー機構が設けられている。
また、上記継ぎ手部材であって挿入穴部あるいは軸部とは反対側には雄ネジ部を設け、この雄ネジ部が塗装用ローラのハンドルに形成した雌ネジ部とねじ結合できる構成にしている。
そして、上記軸部を上記挿入穴部に挿入したとき、上記連結部材、継ぎ手部材及び連結部材に連続する上記長尺柄のそれぞれが軸方向を同じにして連結される。
さらに、上記挿入穴部の開口側に拡径部を形成し、この拡径部の内径を挿入穴部の内径よりも大径にして、挿入穴部と拡径部との境界部分に、上記開口の円周方向に連続する段差面を形成している。そして、この段差面には、段差面と一体形成した複数の弾性片を上記円周方向に沿って連続して起立させている。
上記のようにした弾性片の外側面が上記円周方向に連続して形成する外周円の直径が、上記拡径部の内径よりも小さくし、弾性片の上記外周円と拡径部の内周面との間にすき間が形成されるようにしている。したがって、各弾性片は、上記すき間の範囲でたわんで反り返えることができる。
しかも、上記弾性片の内側面が上記円周方向に連続して形成する内周円の直径は、上記軸部の外径よりも小さくして、上記軸部が上記内周円内に圧入されたとき、各弾性片が上記すき間方向にたわんで、上記軸部に対して径方向及び軸方向に弾性力が発揮される構成にしている。
A stopper mechanism is provided on either the connecting member or the joint member to prevent the shaft inserted into the insertion hole from coming out.
Further, a male threaded portion is provided on the opposite side of the coupling member from the insertion hole portion or the shaft portion, and the male threaded portion is configured to be screwed together with a female threaded portion formed on the handle of the painting roller. .
When the shaft portion is inserted into the insertion hole, the connecting member, the joint member, and the elongated handle continuous to the connecting member are connected in the same axial direction.
Furthermore, an enlarged diameter part is formed on the opening side of the insertion hole, and the inner diameter of the enlarged diameter part is made larger than the inner diameter of the insertion hole, and the enlarged diameter part is formed at the boundary between the insertion hole and the enlarged diameter part. A step surface is formed that is continuous in the circumferential direction of the opening. A plurality of elastic pieces integrally formed with the stepped surface are continuously erected along the circumferential direction.
The diameter of the outer circle formed continuously in the circumferential direction by the outer surface of the elastic piece as described above is smaller than the inner diameter of the enlarged diameter part, and the outer circumference of the elastic piece and the inner diameter of the enlarged diameter part are A gap is formed between the outer surface and the surrounding surface. Therefore, each elastic piece can bend and warp within the range of the gap.
Moreover, the diameter of the inner circle formed by the inner surface of the elastic piece continuously in the circumferential direction is smaller than the outer diameter of the shaft, so that the shaft is press-fitted into the inner circle. When this occurs, each elastic piece bends in the direction of the gap, and elastic force is exerted in the radial and axial directions with respect to the shaft portion.

第2の発明は、上記軸部を断面円形にするとともに、その円形の一部を軸方向に伸びる軸側平坦面としている。また、上記挿入穴部には、上記軸側平坦面と対応する穴側平坦面を形成し、これら軸側平坦面と穴側平坦面とで回り止め機構を構成している。
そして、上記軸側平坦面には止め穴を形成し、上記挿入穴部を形成した連結部材あるいは継ぎ手部材にストッパー機構を設け、このストッパー機構は、上記穴側平坦面に対応する位置に上記挿入穴部の径方向に突出可能にしたストッパーピンが設けられ、このストッパーピンを挿入穴部側に突出させたりあるいは引っ込めたりして、上記挿入穴部側に突出したストッパーピンが上記止め穴にはまり合ったり抜けたりできる構成にしている。
In a second aspect of the invention, the shaft portion has a circular cross section, and a portion of the circular portion is a flat surface on the shaft side extending in the axial direction. Further, the insertion hole portion is formed with a hole-side flat surface corresponding to the shaft-side flat surface, and the shaft-side flat surface and the hole-side flat surface constitute a rotation prevention mechanism.
A stop hole is formed in the flat surface on the shaft side, and a stopper mechanism is provided in the connecting member or joint member in which the insertion hole is formed, and the stopper mechanism is inserted into the shaft at a position corresponding to the flat surface on the hole side. A stopper pin that can protrude in the radial direction of the hole is provided, and by protruding or retracting the stopper pin toward the insertion hole, the stopper pin protruding toward the insertion hole fits into the stopper hole. It has a structure that allows it to fit in and out.

第1の発明の長尺柄連結機構によれば、継ぎ手部材と連結部材とは、軸部と挿入穴部とを軸方向に相対移動させられるので、それらを軸方向に押したり引いたりする力で両者を連結したり分離したりできる。このように軸方向に押したり引いたりする力は、細い長尺柄4を回すときよりも大きな力を発揮できる。 According to the elongated handle connection mechanism of the first invention, since the joint member and the connection member can move the shaft portion and the insertion hole relative to each other in the axial direction, a force that pushes or pulls them in the axial direction is applied. You can connect or separate the two. The force of pushing and pulling in the axial direction in this way can exert a larger force than when turning the thin long handle 4.

したがって、挿入穴部と軸部との間に塗料がしみ込んだとしても、軸部を挿入穴から強い力でそれを引き抜いて分離できる。このように挿入穴部と軸部との間に塗料がしみ込んでも、それを大きな力で分離できるので、例えば、従来のように、作業途中でそれらを洗浄液に浸すような無駄な時間を費やしたり、ローラ部材が不用意に回されたり振れたりしてそこに含まれている塗料が飛散するようなことがない。 Therefore, even if paint seeps into the space between the insertion hole and the shaft, the shaft can be separated from the insertion hole by being pulled out with strong force. In this way, even if paint seeps into the space between the insertion hole and the shaft, it can be separated using a large amount of force. Therefore, the paint contained therein will not be scattered due to the roller member being carelessly rotated or shaken.

しかも、ハンドルに雌ネジ部が形成されている既成の塗装用ローラのハンドルに加工を加えることなくそのまま使うことができる。
さらに、連結部材あるいは継ぎ手部材には、挿入穴部に挿入された軸部が抜けるのを防止するストッパー機構を設けたので、塗装作業中に塗装用ローラと長尺柄とが不用意に分離することはない。
また、弾性片が段差面を介して本体と一体に形成されているので、連結部材を耐溶剤性の材質で構成することによって、塗料に含まれる溶剤の影響でその弾性力が減衰されることはない。また、弾性片は段差面と一体なので、それらを別部材にした場合と異なり、組付け性が問題にならないし、それらを紛失することもない。
さらに、複数の弾性片の総合的な弾性力を軸部に作用させられるので、個々の弾性片の弾性力が多少ばらついても、全体的にはその弾性力を安定化させることができる。
Moreover, the handle of an existing painting roller, which has a female threaded portion formed in the handle, can be used as is without any modification.
Furthermore, the connecting member or joint member is equipped with a stopper mechanism that prevents the shaft inserted into the insertion hole from coming out, which prevents the painting roller and the long handle from inadvertently separating during painting work. Never.
In addition, since the elastic piece is formed integrally with the main body via the stepped surface, by making the connecting member from a solvent-resistant material, the elastic force of the elastic piece is attenuated by the influence of the solvent contained in the paint. There isn't. Furthermore, since the elastic pieces are integrated with the stepped surface, unlike when they are separate members, there is no problem with ease of assembly, and there is no chance of them being lost.
Furthermore, since the overall elastic force of the plurality of elastic pieces can be applied to the shaft portion, even if the elastic force of the individual elastic pieces varies somewhat, the elastic force can be stabilized as a whole.

第2の発明の長尺柄連結機構によれば、軸側平坦面と穴側平坦面とを一致させて軸部を挿入穴部に挿入すれば、ストッパーピンと止め穴との相対位置を必然的に定めることができる。 According to the elongated handle connection mechanism of the second invention, if the shaft part is inserted into the insertion hole with the shaft side flat surface and the hole side flat surface aligned, the relative position of the stopper pin and the stop hole can be adjusted automatically. can be determined.

以下にこの発明の参考例となる第1実施形態と、この発明の実施例となる第2実施形態とを説明する。
図1~図3はこの発明の第1実施形態を示すもので、図1においては長尺柄4の先端部分のみを示している。そして、この長尺柄4は従来の構造と基本的には同じであって、その先端に雄ネジ部6を形成している。そして、長尺柄4の構造は、図7,8に示した従来のものと同一である。
A first embodiment serving as a reference example of the present invention and a second embodiment serving as an example of the present invention will be described below.
1 to 3 show a first embodiment of the present invention, and in FIG. 1 only the tip portion of the elongated handle 4 is shown. This elongated handle 4 has basically the same structure as the conventional one, and has a male threaded portion 6 formed at its tip. The structure of the long handle 4 is the same as the conventional one shown in FIGS. 7 and 8.

また、連結部材Aは筒状の本体8からなり、この本体8の一方の開口には雌ネジ部9を形成し、この雌ネジ部9に長尺柄4の雄ネジ部6がねじ結合される構成にしている。
なお、図1中符号10は、本体8であって雌ネジ部9に対応する外周部分に軸方向に長さを保った滑り止め溝で、本体8の周方向にほぼ等間隔に複数形成したものである。このようにした滑り止め溝10は、この滑り止め溝10が形成された部分を握って、本体8を長尺柄4と相対回転させるとき、滑り止め機能を発揮するものである。
Further, the connecting member A consists of a cylindrical main body 8, and one opening of this main body 8 is formed with a female threaded portion 9, and the male threaded portion 6 of the elongated handle 4 is screwed to this female threaded portion 9. The configuration is as follows.
In addition, the reference numeral 10 in FIG. 1 indicates a plurality of anti-slip grooves whose length is maintained in the axial direction on the outer peripheral portion of the main body 8 corresponding to the female screw portion 9, and a plurality of grooves are formed at approximately equal intervals in the circumferential direction of the main body 8. It is something. The anti-slip groove 10 thus constructed exhibits an anti-slip function when the main body 8 is rotated relative to the elongated handle 4 by grasping the portion in which the anti-slip groove 10 is formed.

連結部材Aの本体8の上記雌ネジ部9とは反対側には挿入穴部11を形成するとともに、この挿入穴部11の開口部分には上記挿入穴部11の内径よりも大きくした拡径部12を連続させている。したがって、この拡径部12と挿入穴部11との間の境界部分には、それら挿入穴部と拡径部との段差分に相当した段差面13が円周方向に連続的に形成される。このようにした段差面13は軸線にほぼ直交する。
さらに、挿入穴部11内には軸方向に伸びる肉厚部14を円周方向に1か所形成し、この肉厚部14を段差面13に臨ませるとともに、この肉厚部14の内面を穴側平坦面15としている。
なお、上記穴側平坦面15は必要に応じて複数個所設けてもよい。
An insertion hole 11 is formed on the opposite side of the body 8 of the connecting member A from the female threaded portion 9, and the opening of the insertion hole 11 has an enlarged diameter larger than the inner diameter of the insertion hole 11. Section 12 is made continuous. Therefore, at the boundary between the enlarged diameter portion 12 and the insertion hole 11, a stepped surface 13 corresponding to the step between the insertion hole and the enlarged diameter portion is continuously formed in the circumferential direction. . The step surface 13 formed in this manner is substantially orthogonal to the axis.
Furthermore, a thick wall portion 14 extending in the axial direction is formed at one location in the circumferential direction within the insertion hole portion 11, and this thick wall portion 14 is made to face the step surface 13, and the inner surface of this thick wall portion 14 is The hole side has a flat surface 15.
Note that the hole-side flat surface 15 may be provided at a plurality of locations as necessary.

上記のようにした肉厚部14には、ストッパーピン16を挿入穴部11の直径方向に貫通させるとともに、このストッパーピン16の先端を挿入穴部11内に突出させたり、挿入穴部11から退避させたりするレバー17を本体8の外部に設けている。 A stopper pin 16 is passed through the thick wall portion 14 in the diametrical direction of the insertion hole 11, and the tip of the stopper pin 16 is made to protrude into the insertion hole 11 or from the insertion hole 11. A lever 17 for retracting is provided outside the main body 8.

上記のようにしたレバー17は回動支点18を中心に回動自在であって、図示していないスプリングのばね力で、通常は図示の位置を保ち、ストッパーピン16を挿入穴部11内に突出させている。そして、レバー17を、支点18を中心に上記スプリングのばね力に抗して回動させると、ストッパーピン16が挿入穴部11から退避する構成にしている。 The lever 17 configured as described above is rotatable about the rotation fulcrum 18, and is normally maintained at the position shown in the drawing by the force of a spring (not shown), and the stopper pin 16 is inserted into the insertion hole 11. It stands out. When the lever 17 is rotated about the fulcrum 18 against the spring force of the spring, the stopper pin 16 is retracted from the insertion hole 11.

一方、上記連結部材Aに連結される継ぎ手部材Bは、フランジ部21を挟んでその軸方向の一方を軸部19とし、他方を雄ネジ部20としている。しかも、上記軸部19とフランジ部21との間には、軸部19の外径よりも大きく、フランジ部21の外径よりも小さい外径を保持した大径部19aを設けるとともに、この大径部19aを連結部材Aの拡径部12に挿入可能にしている。 On the other hand, the joint member B connected to the connecting member A has a shaft portion 19 on one side in the axial direction with the flange portion 21 in between, and a male screw portion 20 on the other side. Furthermore, a large diameter portion 19a having an outer diameter larger than the outer diameter of the shaft portion 19 and smaller than the outer diameter of the flange portion 21 is provided between the shaft portion 19 and the flange portion 21. The diameter portion 19a can be inserted into the enlarged diameter portion 12 of the connecting member A.

上記軸部19は断面形状を円形にするとともに、その外径を挿入穴部11とほぼ同じにして、軸部19が挿入穴部11にスムーズに挿入されるようにしている。さらに、この軸部19の円形の一部を、図3に示すように軸方向に伸びる軸側平坦面22とし、この軸側平坦面22にはストッパーピン16が挿入される止め穴23が形成されている。したがって、軸部19の軸側平坦面22と挿入穴部11の穴側平坦面15とを合わせて軸部19を挿入穴部11に挿入すれば、ストッパーピン16と止め穴23とが同一面側に位置する。
なお、この軸側平坦面22は、上記穴側平坦面15と個数も場所も対応させている。
The shaft portion 19 has a circular cross-sectional shape, and its outer diameter is approximately the same as the insertion hole portion 11, so that the shaft portion 19 can be smoothly inserted into the insertion hole portion 11. Furthermore, as shown in FIG. 3, a circular part of this shaft portion 19 is formed into a shaft-side flat surface 22 extending in the axial direction, and a stop hole 23 into which the stopper pin 16 is inserted is formed in this shaft-side flat surface 22. has been done. Therefore, if the shaft 19 is inserted into the insertion hole 11 by aligning the shaft-side flat surface 22 of the shaft 19 with the hole-side flat surface 15 of the insertion hole 11, the stopper pin 16 and the stopper hole 23 will be on the same plane. located on the side.
The shaft-side flat surface 22 corresponds to the hole-side flat surface 15 in number and location.

上記フランジ部21の外径は、上記拡径部12の外径とほぼ一致させ、軸部19を挿入穴部11の軸方向に押し込んだとき、フランジ部21が拡径部12の縁に当たるとともに、それらが当たった位置で、それ以上軸部19を押し込めない状態になる。
なお、符号19bは、軸部19の先端に形成した面取り部である。
The outer diameter of the flange portion 21 is made to substantially match the outer diameter of the enlarged diameter portion 12, so that when the shaft portion 19 is pushed in the axial direction of the insertion hole 11, the flange portion 21 hits the edge of the enlarged diameter portion 12 and , and at the position where they hit, the shaft portion 19 cannot be pushed in any further.
Note that the reference numeral 19b is a chamfered portion formed at the tip of the shaft portion 19.

上記大径部19aにはパッキン24をはめるが、このパッキン24は、図2に示すように、筒部24aとこの筒部24aの開口部分に形成したつば部24bとからなる。そして、上記筒部24aの外径は、連結部材Aの上記拡径部12の内径よりもわずかに大きくし、この筒部24aを弾圧しながら拡径部12に圧入できる寸法関係を維持している。 A packing 24 is fitted into the large diameter portion 19a, and as shown in FIG. 2, the packing 24 consists of a cylindrical portion 24a and a flange portion 24b formed at the opening of the cylindrical portion 24a. The outer diameter of the cylindrical portion 24a is made slightly larger than the inner diameter of the enlarged diameter portion 12 of the connecting member A, and a dimensional relationship is maintained such that the cylindrical portion 24a can be press-fitted into the enlarged diameter portion 12 while being pressed. There is.

一方、つば部24bは、継ぎ手部材Bのフランジ部21を連結部材Aの拡径部12の外径に押し付けてこのつば部24bを弾圧したとき、上記ストッパーピン16と止め穴23との相対位置が一致するようにしている。
したがって、レバー17を上記スプリングのばね力に抗して回動し、ストッパーピン16を上記した退避状態に保って継ぎ手部材Bの軸部19を、連結部材Aの挿入穴部11に挿入するとともに、つば部24bを弾圧した状態でレバー17を開放すれば、ストッパーピン16が図示していないスプリングのばね力で挿入穴部11側に突出して、ストッパーピン16が止め穴23にはまることになる。
なお、これらストッパーピン16と止め穴23とで、この発明のストッパー機構を構成するものである。
On the other hand, when the flange portion 21 of the joint member B is pressed against the outer diameter of the enlarged diameter portion 12 of the connecting member A and the collar portion 24b is pressed, the relative position of the stopper pin 16 and the stop hole 23 is determined by the flange portion 24b. are made to match.
Therefore, the lever 17 is rotated against the spring force of the spring, the stopper pin 16 is kept in the retracted state, and the shaft part 19 of the joint member B is inserted into the insertion hole part 11 of the connecting member A. If the lever 17 is released while the collar 24b is pressed, the stopper pin 16 will protrude toward the insertion hole 11 side by the force of a spring (not shown), and the stopper pin 16 will fit into the stopper hole 23. .
The stopper pin 16 and the stopper hole 23 constitute the stopper mechanism of the present invention.

上記のようにしてパッキン24を弾圧した状態でそれを拡径部12に押し込めば、筒部24aによって径方向の弾性力が作用するとともに、つば部24bによって軸方向の弾性力が作用することになる。
したがって、連結部材Aの拡径部12の内径と、大径部19aの外径との間に多少の寸法誤差があったとしても、上記筒部24aの軸方向の弾性力でその寸法誤差は吸収される。このようにがたつきがあってもそれが吸収されるので、例えば継ぎ手部材Bの雄ネジ部20に連結された塗装用ローラRに対するがたつきが吸収される。もし、長尺柄4の先端における塗装用ローラRががたつくと、塗装作業に支障をきたすが、上記パッキン24の弾性力で作業に対する悪影響を防止できる。
When the packing 24 is compressed as described above and is pushed into the enlarged diameter portion 12, an elastic force in the radial direction is applied by the cylinder portion 24a, and an elastic force in the axial direction is applied by the collar portion 24b. Become.
Therefore, even if there is some dimensional error between the inner diameter of the enlarged diameter portion 12 of the connecting member A and the outer diameter of the large diameter portion 19a, the dimensional error is eliminated by the axial elastic force of the cylindrical portion 24a. Absorbed. Even if there is any wobbling, it is absorbed, so that, for example, the wobbling of the coating roller R connected to the male threaded portion 20 of the joint member B is absorbed. If the coating roller R at the tip of the long handle 4 shakes, it will interfere with the coating operation, but the elastic force of the packing 24 can prevent any adverse effects on the operation.

一方、上記つば部24bは、拡径部12の開口縁とフランジ部21との間に挟まれて弾圧されることによって、連結部材Aと継ぎ手部材Bの両者を軸方向に分離する弾性力を発揮し、それらのがたつきを吸収できる。このようにがたつきを吸収できるので、ストッパーピン16に対して止め穴23を多少大きめにしてもよくなり、止め穴23の厳密な加工精度が求められなくなり、その分、製造効率を上げることができる。 On the other hand, the flange portion 24b is pinched and pressed between the opening edge of the enlarged diameter portion 12 and the flange portion 21, thereby exerting an elastic force that separates both the connecting member A and the joint member B in the axial direction. and can absorb those fluctuations. Since rattling can be absorbed in this way, it is possible to make the stop hole 23 a little larger than the stopper pin 16, and strict machining accuracy of the stop hole 23 is no longer required, which increases manufacturing efficiency accordingly. I can do it.

上記のようにした長尺柄連結機構は、先ず、継ぎ手部材Bの雄ネジ部20を塗装用ローラRのハンドル1に形成された雌ネジ部5にねじ結合して、継ぎ手部材Bをハンドル1に連結する。
また、長尺柄4の雄ネジ部6を連結部材Aの雌ネジ部9にねじ結合して、長尺柄4と連結部材Aとを連結する。
In the long handle connection mechanism as described above, first, the male threaded part 20 of the joint member B is screwed to the female threaded part 5 formed on the handle 1 of the painting roller R, and the joint member B is connected to the handle 1. Connect to.
Further, the male threaded portion 6 of the elongated handle 4 is screwed to the female threaded portion 9 of the connecting member A to connect the elongated handle 4 and the connecting member A.

次に、連結部材Aの挿入穴部11に、継ぎ手部材Bの軸部19を挿入するとともに、そのフランジ部21と連結部材Aの拡径部12の開口縁との間で、パッキン24のつば部24bを強く弾圧するまで軸部19を挿入穴部11に押し込む。この過程では、ストッパーピン16を強制的に退避させておくとともに、止め穴23と一致した段階で、レバー17を開放してストッパーピン16を止め穴23にはめる。 Next, the shaft part 19 of the joint member B is inserted into the insertion hole 11 of the joint member A, and the brim of the packing 24 is inserted between the flange part 21 and the opening edge of the enlarged diameter part 12 of the joint member A. Push the shaft portion 19 into the insertion hole portion 11 until the portion 24b is strongly pressed. In this process, the stopper pin 16 is forcibly retracted, and when it is aligned with the stopper hole 23, the lever 17 is released and the stopper pin 16 is fitted into the stopper hole 23.

上記のようにストッパーピン16が止め穴23にはまった状態では、パッキン24のつば部24bの弾性力が軸部19の軸方向に作用するので、ストッパーピン16が止め穴23から抜けたりがたついたりすることが防止されるとともに、長尺柄4とハンドル1との相対回転も防止される。そのために、塗装用ローラRのローラ部材3の向きなどが安定し、塗装作業がやりやすくなる。
なお、上記穴側平坦面15、軸側平坦面22、ストッパーピン16及び止め穴23が相まってこの発明の回り止め機構を構成する。
When the stopper pin 16 is fitted into the stopper hole 23 as described above, the elastic force of the flange portion 24b of the packing 24 acts in the axial direction of the shaft portion 19, so that the stopper pin 16 does not come out from the stopper hole 23. This prevents the elongated handle 4 and the handle 1 from rotating relative to each other. Therefore, the direction of the roller member 3 of the coating roller R is stabilized, and the coating operation becomes easier.
Note that the hole-side flat surface 15, shaft-side flat surface 22, stopper pin 16, and stopper hole 23 together constitute the detent mechanism of the present invention.

一方、長尺柄4をハンドル1から外すときには、レバー17を図示していないスプリングのばね力に抗して回動して、ストッパーピン16を挿入穴部11から退避させるとともに、継ぎ手部材Bの軸部19と連結部材Aの挿入穴部11とを軸方向に相対移動させて、言い換えると、継ぎ手部材Bと連結部材Aとを反対方向に引っ張って両者を分離させる。 On the other hand, when removing the elongated handle 4 from the handle 1, the lever 17 is rotated against the force of a spring (not shown) to retract the stopper pin 16 from the insertion hole 11 and to remove the joint member B. The shaft portion 19 and the insertion hole 11 of the connecting member A are moved relative to each other in the axial direction, in other words, the joint member B and the connecting member A are pulled in opposite directions to separate them.

そして、ハンドル1側に残った継ぎ手部材Bは、そのままハンドル1に取り付けたままにしておいてもよいし、塗装作業終了後にゆっくりと洗浄液に浸してそれらを分離してもよい。
なお、上記第1実施形態では、長尺柄4と連結部材Aとを別部材にしたが、長尺柄4の先端に連結部材Aと同一の構成を一体的に設けるようにしてもよい。
The joint member B remaining on the handle 1 side may be left attached to the handle 1 as it is, or may be separated by being slowly immersed in a cleaning liquid after the painting work is completed.
In the first embodiment, the long handle 4 and the connecting member A are separate members, but the same structure as the connecting member A may be integrally provided at the tip of the long handle 4.

図4,5に示した第2実施形態は、連結部材Aのみを第1実施形態と相違させたもので、継ぎ手部材Bは第1実施形態におけるパッキン24を不要にした以外はすべて同じである。つまり、第2実施形態の継ぎ手部材Bには、先端に面取り部19bを備えた軸部19と、大径部19aとを備えている。また、この軸部19には、連結部材Aの穴側平坦面15と対応づけられた軸側平坦面22を設けるとともに、この軸側平坦面22には連結部材Aのストッパーピン16と対応づけられた止め穴23を形成し、さらに、大径部19aと雄ネジ部20との間にフランジ部21を設けている。 The second embodiment shown in FIGS. 4 and 5 is different from the first embodiment only in the connecting member A, and the joint member B is the same as the first embodiment except that the packing 24 is not required. . That is, the joint member B of the second embodiment includes a shaft portion 19 having a chamfered portion 19b at its tip and a large diameter portion 19a. Further, this shaft portion 19 is provided with a shaft-side flat surface 22 that corresponds to the hole-side flat surface 15 of the connecting member A, and this shaft-side flat surface 22 is provided with a shaft-side flat surface 22 that corresponds to the stopper pin 16 of the connecting member A. A stop hole 23 is formed, and a flange portion 21 is further provided between the large diameter portion 19a and the male screw portion 20.

また、この第2実施形態の連結部材Aも、拡径部12における構成が第1実施形態の連結部材Aと相違するのみで、その他の構成はすべて第1実施形態と同じである。
つまり、この第2実施形態の連結部材Aは、本体8に挿入穴部11を形成し、挿入穴部11に連続する拡径部12を形成し、これら挿入穴部11と拡径部12との境界部分に段差面13を形成している。また、上記挿入穴部11に設けた肉厚部14に設けた穴側平坦面15と、この穴側平坦面14を貫通するとともに止め穴23と対応づけられたストッパーピン16と、このストッパーピン16を挿入穴部11に突出させたり退避させたりするレバー17とを設けている。しかも、これらストッパーピン16と止め穴23とが相まって、この発明のストッパー機構を構成する点も、第1実施形態と同じである。
Further, the connecting member A of the second embodiment is also different from the connecting member A of the first embodiment only in the configuration of the enlarged diameter portion 12, and all other configurations are the same as the first embodiment.
In other words, the connecting member A of the second embodiment has an insertion hole 11 formed in the main body 8, an enlarged diameter section 12 continuous to the insertion hole 11, and a connection between the insertion hole 11 and the enlarged diameter section 12. A step surface 13 is formed at the boundary portion. Further, a hole-side flat surface 15 provided on the thick wall portion 14 provided in the insertion hole portion 11, a stopper pin 16 that passes through this hole-side flat surface 14 and is associated with the stopper hole 23, and this stopper pin. A lever 17 is provided for projecting and retracting the insertion hole 16 into the insertion hole 11. Furthermore, the stopper pin 16 and the stopper hole 23 together constitute the stopper mechanism of the present invention, which is the same as in the first embodiment.

第2実施形態における連結部材Aの拡径部12であって円周方向に連続する段差面13には、複数の弾性片25を上記円周方向に沿って連続して起立させている。なお、これら弾性片25は、段差面13を介して本体8と一体に設けている。そして、これら各弾性片25の先端には、軸部19の面取り部19bを導入するための円弧部25aを形成している。
このようにした弾性片25は、それら弾性片25の外側面が上記円周方向に連続して形成される外周円の直径を上記拡径部12の内径よりも小さくして、弾性片25と拡径部12の内面との間にすき間26が形成されるようにしている。したがって、各弾性片25は上記すき間26の方向にたわむことができる。
A plurality of elastic pieces 25 are continuously erected along the circumferential direction on a stepped surface 13 that is the enlarged diameter portion 12 of the connecting member A in the second embodiment and is continuous in the circumferential direction. Note that these elastic pieces 25 are provided integrally with the main body 8 via the step surface 13. At the tip of each of these elastic pieces 25, an arcuate portion 25a is formed into which the chamfered portion 19b of the shaft portion 19 is introduced.
The elastic pieces 25 thus constructed are formed by making the diameter of the outer circumferential circle formed continuously in the circumferential direction smaller than the inner diameter of the enlarged diameter portion 12. A gap 26 is formed between the enlarged diameter portion 12 and the inner surface thereof. Therefore, each elastic piece 25 can be bent in the direction of the gap 26.

また、各弾性片25の内側面が上記円周方向に連続して形成される内周円の直径を、軸部19の大径部19a外径よりも小さくしている。したがって、軸部19の大径部19aを上記内周円に圧入したとき、大径部19aが円弧部25aに当たって弾性片25が押し広げられ、各弾性片25が上記すき間26方向にたわむことになる。 Further, the diameter of the inner circumferential circle in which the inner surface of each elastic piece 25 is continuously formed in the circumferential direction is smaller than the outer diameter of the large diameter portion 19a of the shaft portion 19. Therefore, when the large diameter portion 19a of the shaft portion 19 is press-fitted into the inner circumferential circle, the large diameter portion 19a hits the circular arc portion 25a and the elastic pieces 25 are pushed apart, causing each elastic piece 25 to bend in the direction of the gap 26. Become.

また、上記各弾性片25のうち上記円周方向における90度の間隔を保って位置する4つの弾性片25の根元には止め段部27を形成している。この止め段部27は、上記内周円に圧入された軸部19の位置決めをするもので、軸部19がこの止め段部27に当たってそれ以上押し込めない位置において、上記ストッパーピン16と止め穴23とが対応するようにしている。 Furthermore, stopper steps 27 are formed at the bases of four of the elastic pieces 25 that are positioned at 90 degree intervals in the circumferential direction. This stopper step 27 is for positioning the shaft portion 19 press-fitted into the inner circumferential circle, and when the shaft portion 19 hits this stopper step 27 and cannot be pushed in any further, the stopper pin 16 and stopper hole 2 I am trying to make it correspond to the above.

なお、この第2実施形態においても、上記連結部材Aに挿入穴部11が形成され、継ぎ手部材Bに軸部19が形成されているが、それらの構成は相対的であって、いずれか一方に挿入穴部11を形成し、いずれか他方に軸部19が形成されていればよい。この点も第1実施形態と同じである。 In this second embodiment as well, the insertion hole portion 11 is formed in the connecting member A, and the shaft portion 19 is formed in the joint member B, but these structures are relative, and either one of them is formed. It is sufficient that the insertion hole portion 11 is formed on one side and the shaft portion 19 is formed on the other side. This point is also the same as the first embodiment.

次に、連結部材Aと継ぎ手部材Bとを連結する過程を説明する。
まず、連結部材Aの挿入穴部11に、継ぎ手部材Bの軸部19を挿入するが、このとき、大径部19aが各弾性片25に形成した円弧部25aに摺接して各弾性片25の上記内周円を拡径する。したがって、各弾性片25はすき間26の方向にたわみ、各弾性片25には軸部19に圧接する方向の弾性力が作用する。
Next, the process of connecting the connecting member A and the joint member B will be explained.
First, the shaft portion 19 of the joint member B is inserted into the insertion hole portion 11 of the connecting member A. At this time, the large diameter portion 19a slides against the arcuate portion 25a formed on each elastic piece 25, and each elastic piece 25 The diameter of the inner circumferential circle is expanded. Therefore, each elastic piece 25 is bent in the direction of the gap 26, and an elastic force acts on each elastic piece 25 in the direction of pressing against the shaft portion 19.

そして、軸部19が各弾性片25の止め段部27に当たった段階で、ストッパーピン16と止め穴23とがはまり合うことになる。なお、このように軸部19を挿入穴部11に挿入する過程では、ストッパーピン16を強制的に退避させておく。そして、ストッパーピン16と止め穴23とが一致した段階でレバー17を開放し、ストッパーピン16を止め穴23にはめる。 Then, when the shaft portion 19 hits the stopper step 27 of each elastic piece 25, the stopper pin 16 and the stopper hole 23 fit together. In addition, in the process of inserting the shaft portion 19 into the insertion hole portion 11 in this manner, the stopper pin 16 is forcibly retracted. Then, when the stopper pin 16 and the stopper hole 23 are aligned, the lever 17 is released and the stopper pin 16 is fitted into the stopper hole 23.

上記のようにストッパーピン16が止め穴23にはまった状態では、軸部19に対して各弾性片25の弾性力が径方向に作用するととも軸方向にも作用することになる。したがって、これら弾性片25は第1実施形態のパッキン24と同一の作用効果を発揮する。ただし、弾性片25が本体8と一体に形成されているので、連結部材Aを耐溶剤性の材質で構成することによって、塗料に含まれる溶剤の影響でその弾性力が減衰されることはない。また、弾性片25は段差面13と一体なので、それらを別部材にした場合と異なり、組付け性が問題にならないし、それらを紛失することもない。 When the stopper pin 16 is fitted into the stopper hole 23 as described above, the elastic force of each elastic piece 25 acts on the shaft portion 19 not only in the radial direction but also in the axial direction. Therefore, these elastic pieces 25 exhibit the same effect as the packing 24 of the first embodiment. However, since the elastic piece 25 is formed integrally with the main body 8, since the connecting member A is made of a solvent-resistant material, its elastic force will not be attenuated by the influence of the solvent contained in the paint. . Further, since the elastic piece 25 is integrated with the step surface 13, unlike the case where they are separate members, there is no problem with ease of assembly, and there is no possibility of losing them.

さらに、複数の弾性片25の総合的な弾性力を軸部19に作用させられるので、個々の弾性片25の弾性力が多少ばらついても、全体的にはその弾性力を安定化させることができる。
なお、この第2実施形態においても上記穴側平坦面15及び軸側平坦面22が相まってこの発明の回り止め機構を構成する。
Furthermore, since the overall elastic force of the plurality of elastic pieces 25 can be applied to the shaft portion 19, even if the elastic force of the individual elastic pieces 25 varies somewhat, the elastic force can be stabilized as a whole. can.
In this second embodiment as well, the hole-side flat surface 15 and the shaft-side flat surface 22 together constitute the detent mechanism of the present invention.
