Description

本発明は、レバーアッセンブリ塗装方法に関するものである。 The present invention relates to lever assembly coating method.

従来、車両ウィンドの払拭面を払拭するためのワイパとしては、例えばワイパ全体(ブレードラバー含む)を白色一色に塗装することで、運転者の目に優しくしようとしたものがある(例えば、特許文献1参照)。   Conventionally, as a wiper for wiping the wiping surface of a vehicle window, for example, there is a wiper that is intended to be easy on the driver's eyes by painting the entire wiper (including blade rubber) in a single color (for example, Patent Documents). 1).

特開2006−232244号公報JP 2006-232244 A

ところで、ワイパの一部を構成しブレードラバーを保持するレバーアッセンブリは、ブレードラバーを払拭面に良好に追従させるため等の理由で、例えば、複数のレバーが回動可能にトーナメント状に連結される。よって、レバーアッセンブリ(組み付けられた複数のレバー)を塗装する際、レバー回動部(レバーの連結部分)の状態が不安定であると塗装が製品毎にばらつくといった虞がある。又、レバーアッセンブリは、塗装する必要がない部分や塗装しない方が良い部分があることが考えられ、一般的に部分的にレバー非塗装部を設ける場合、マスキングテープ等を用いることが考えられるが、製品毎にマスキングテープ等を使うことは製品コストを増大させる原因となる。   By the way, the lever assembly that constitutes a part of the wiper and holds the blade rubber is, for example, a plurality of levers rotatably connected to a tournament for the reason that the blade rubber follows the wiping surface well. . Therefore, when painting the lever assembly (a plurality of assembled levers), there is a risk that the coating may vary from product to product if the state of the lever rotating portion (the connecting portion of the lever) is unstable. The lever assembly may have a part that does not need to be painted or a part that should not be painted. In general, when the lever non-painted part is partially provided, it may be possible to use a masking tape or the like. The use of masking tape or the like for each product increases the product cost.

本発明は上記問題点を解消するためになされたものであって、その目的は、レバーアッセンブリをばらつきなく安価に塗装することができるレバーアッセンブリ塗装方法を提供することにある。 The present invention was made to solve the above problems, its object is to provide a Relais bar assembly coating method can be inexpensively coated without variations the lever assembly.

The engaging piece 22b is formed to have substantially the same width as the hook portion 11a of the wiper arm 11, and has a substantially U shape in a side view so as to once again go upward and downward. The engagement piece 22b has a curved surface 22c that follows the outer peripheral surface 11c of the arc portion of the hook portion 11a at a portion facing upward again. When the locking member 22 is rotated to the locking position, the engaging piece 22b has its curved surface 22c abutting with the outer peripheral surface 11c of the hook portion 11a mounted on the mounting portion 21c of the base member 21 with an elastic force. The engagement piece 22b and the mounting portion 21c elastically hold the arc portion of the hook portion 11a. At this time, the upper side opening (non-wiping surface side opening) of the insertion space 21x is covered and closed by the lock member 22 in the locked state rotated to the lock position. As described above, the connecting member 20 is rotatably supported by the connecting shaft 17 while being accommodated in the opening 13 b of the lever assembly R (main lever 13), and is attached to the hook portion 11 a of the wiper arm 11. The lever assembly R is pivotally connected to the wiper arm 11.

ここで、ワイパ10のレバーアッセンブリRは塗装されるものであって、レバーアッセンブリRと連結部材20とが相対回動して摺接する部位に対応した回動時摺接部(回動する際に擦れる可能性のある部分)には非塗装部としての連結部材レバー間非塗装部Xa,Xb(図3参照)が設けられている。   Here, the lever assembly R of the wiper 10 is painted, and a sliding contact portion (when rotating) corresponding to a portion where the lever assembly R and the connecting member 20 are relatively rotated and slidably contact each other. Non-painted portions Xa and Xb (see FIG. 3) between the connecting member levers as non-painted portions are provided on the portion that may be rubbed.

詳しくは、まず本実施形態のレバーアッセンブリRにおいて、メインレバー13、ヨークレバー14及び可動カバー部材15は、塗装色(例えば青色)よりも暗い色(例えば紺色)の素材である樹脂材で成形されている。又、連結部材20は、塗装色(例えば青色)と同系色(例えば青色や紺色)の素材である樹脂材で成形されている。   Specifically, in the lever assembly R of the present embodiment, first, the main lever 13, the yoke lever 14, and the movable cover member 15 are molded from a resin material that is a darker (for example, amber) material than a painted color (for example, a blue). ing. The connecting member 20 is formed of a resin material that is a material having a color similar to the paint color (for example, blue) (for example, blue or amber).

そして、メインレバー13及び可動カバー部材15は、後述するレバーアッセンブリ塗装装置及びレバーアッセンブリ塗装方法によって非払拭面側からのみ塗装されている。又、メインレバー13における回動時摺接部である前記開口部13bの内側面13dは、塗装されずに、連結部材レバー間非塗装部Xaとされている。又、本実施形態ではヨークレバー14は、塗装されていない。又、連結部材20は、略全体が塗装されながらも、回動時摺接部である前記外側面21aが塗装されずに、連結部材レバー間非塗装部Xbとされている。   The main lever 13 and the movable cover member 15 are coated only from the non-wiping surface side by a later-described lever assembly painting apparatus and lever assembly painting method. Further, the inner side surface 13d of the opening 13b which is a sliding contact portion in the main lever 13 is not painted but is a non-coating portion Xa between connecting member levers. In this embodiment, the yoke lever 14 is not painted. The connecting member 20 is not painted on the outer side surface 21a, which is a sliding contact portion at the time of rotation, but is a non-painted portion Xb between the connecting members and levers, although the whole is painted.

次に、上記したレバーアッセンブリR(連結部材20は除く)のレバーアッセンブリ塗装装置及びレバーアッセンブリ塗装方法について説明する。
図4(a)(b)に示すように、レバーアッセンブリ塗装装置はマスキング保持部材31を備える。マスキング保持部材31は、前記レバー回動部(メインレバー13とヨークレバー14との連結部分、及びヨークレバー14と可動カバー部材15の連結部分)を一定の(回動)状態(すなわち、レバーアッセンブリR全体を一定の塗装姿勢)に維持しながらレバーアッセンブリRの予め設定された一部をマスキング可能とされている。
Next, a lever assembly coating apparatus and a lever assembly coating method for the above-described lever assembly R (excluding the connecting member 20) will be described.
As shown in FIGS. 4A and 4B, the lever assembly coating apparatus includes a masking holding member 31. The masking holding member 31 has the lever rotating portion (the connecting portion of the main lever 13 and the yoke lever 14 and the connecting portion of the yoke lever 14 and the movable cover member 15) in a constant (turning) state (that is, the lever assembly). A predetermined part of the lever assembly R can be masked while maintaining the entire R in a certain painting posture.

本実施形態のマスキング保持部材31は、レバーアッセンブリRの払拭面G側(図4(b)中、下側であって、レバー非塗装部)をマスキングすべく、メインレバー13及び可動カバー部材15よりも払拭面G側を収容しつつ覆うマスキング収容溝31aを有する。マスキング収容溝31aは、メインレバー13及び可動カバー部材15よりも払拭面G側に突出する把持爪14a,15b等を収容可能に形成されている。尚、本実施形態のマスキング保持部材31は、同時に複数のレバーアッセンブリRを塗装可能とするため、複数のマスキング収容溝31aが並設されている。又、マスキング保持部材31(マスキング収容溝31a)は、レバーアッセンブリRにおける複数の把持爪14a,15bを(長手方向の)一直線状に維持して前記レバー回動部を一定の状態に維持するように形成されている。即ち、このマスキング保持部材31は、複数の把持爪14a,15bがマスキング収容溝31aに挿入されるようにレバーアッセンブリRを載置するだけで、複数の把持爪14a,15bを一直線状に維持して前記レバー回動部を一定の状態、すなわち、レバーアッセンブリR全体を一定の塗装姿勢に維持しながらレバーアッセンブリRの払拭面G側をマスキング可能とされている。   The masking holding member 31 of the present embodiment has a main lever 13 and a movable cover member 15 for masking the wiping surface G side of the lever assembly R (the lower side in FIG. 4B and the lever non-coating portion). It has the masking accommodation groove | channel 31a which covers, covering the wiping surface G side rather than. The masking receiving groove 31a is formed so as to be able to receive the gripping claws 14a, 15b and the like protruding from the main lever 13 and the movable cover member 15 to the wiping surface G side. In addition, the masking holding member 31 of the present embodiment is provided with a plurality of masking receiving grooves 31a in parallel so that a plurality of lever assemblies R can be painted simultaneously. Further, the masking holding member 31 (masking receiving groove 31a) maintains the plurality of gripping claws 14a and 15b in the lever assembly R in a straight line (longitudinal direction) so as to maintain the lever rotating portion in a constant state. Is formed. That is, the masking holding member 31 maintains the plurality of gripping claws 14a and 15b in a straight line simply by placing the lever assembly R so that the plurality of gripping claws 14a and 15b are inserted into the masking receiving grooves 31a. Thus, the wiping surface G side of the lever assembly R can be masked while the lever rotating portion is maintained in a constant state, that is, the entire lever assembly R is maintained in a constant coating posture.

又、本実施形態のレバーアッセンブリ塗装装置は、メインレバー13の前記開口部13bに嵌入されるマスキング嵌入部材32を備える。マスキング嵌入部材32は、前記開口部13bに嵌入されることで開口部13bの内側面13d(図3参照)、即ち前記連結部材レバー間非塗装部Xaを覆い、該部分への塗料の付着、若しくは塗膜層が形成されてしまうことを防止可能に形成されている。   Further, the lever assembly painting apparatus according to the present embodiment includes a masking insertion member 32 that is inserted into the opening 13 b of the main lever 13. The masking insertion member 32 covers the inner side surface 13d (see FIG. 3) of the opening 13b, that is, the non-coating portion Xa between the connecting member levers by being inserted into the opening 13b, and the paint adheres to the portion. Or it is formed so that it can prevent that a coating-film layer will be formed.

そして、レバーアッセンブリ塗装方法では、マスキング保持部材31にて前記レバー回動部を一定の状態(すなわち、レバーアッセンブリR全体を一定の塗装姿勢)に維持しながら、同マスキング保持部材31にてレバーアッセンブリRの予め設定された一部(レバーアッセンブリRの払拭面G側)をマスキングし、更に本実施形態ではマスキング嵌入部材32を前記開口部13bに嵌入して塗装を行う。これにより、レバーアッセンブリR(連結部材20は除く)の塗装が完了される。尚、本実施形態では、塗装は吹き付け塗装を採用している。   In the lever assembly painting method, the mask assembly is maintained by the masking holding member 31 while maintaining the lever rotating portion in a constant state (that is, the entire lever assembly R is in a constant painting posture) by the masking holding member 31. A predetermined part of R (the wiping surface G side of the lever assembly R) is masked, and in this embodiment, the masking insertion member 32 is inserted into the opening 13b for coating. Thereby, the coating of the lever assembly R (excluding the connecting member 20) is completed. In the present embodiment, spray coating is adopted as the coating.

次に、上記のように構成されたワイパ10の作用について説明する。
上記ワイパ10では、図示しない付勢機構によりワイパアーム11の先端側が払拭面G側に付勢され、その付勢力が連結部材20、及びレバーアッセンブリRを介してブレードラバー16に伝達されて、ブレードラバー16が長手方向全長に亘って払拭面Gに押圧接触される。又、車両走行時には、フィン部13z,15zにて走行風が払拭面G側への押圧力に変換されて、ブレードラバー16が払拭面Gに押圧接触される。これらのことから、ワイパ10が往復揺動(回動)されると、良好な払拭動作が行われる。
Next, the operation of the wiper 10 configured as described above will be described.
In the wiper 10, the leading end side of the wiper arm 11 is urged toward the wiping surface G by an urging mechanism (not shown), and the urging force is transmitted to the blade rubber 16 via the connecting member 20 and the lever assembly R, and the blade rubber. 16 is pressed against the wiping surface G over the entire length in the longitudinal direction. Further, when the vehicle is traveling, the traveling wind is converted into a pressing force toward the wiping surface G by the fin portions 13z and 15z, and the blade rubber 16 is pressed against the wiping surface G. For these reasons, when the wiper 10 is reciprocally swung (rotated), a good wiping operation is performed.

次に、上記実施の形態の特徴的な効果を以下に記載する。
(1)塗装対象が複数のレバー(メインレバー13、ヨークレバー14及び可動カバー部材15)が回動自在に連結されているために姿勢が不安定なレバーアッセンブリRであっても、マスキング保持部材31にてレバーアッセンブリRのレバー回動部(メインレバー13とヨークレバー14との連結部分、及びヨークレバー14と可動カバー部材15の連結部分)が一定の(回動)状態(すなわち、レバーアッセンブリR全体が一定(本実施形態では一直線状)の塗装姿勢)に維持されるため、個々のレバーアッセンブリRをばらつきなく安定して塗装を行うことができる(塗装の出来栄えが安定する)。又、マスキング保持部材31にてレバーアッセンブリRの予め設定された一部(レバーアッセンブリRの払拭面G側)がマスキングされるため、別途マスキングテープ等を必要とせず、安価にレバー非塗装部(レバーアッセンブリRの払拭面G側)を設けつつ塗装することができる。
Next, the characteristic effects of the above embodiment will be described below.
(1) Even if the object to be coated is a lever assembly R whose posture is unstable because a plurality of levers (main lever 13, yoke lever 14 and movable cover member 15) are rotatably connected, a masking holding member 31, the lever rotating portion of the lever assembly R (the connecting portion between the main lever 13 and the yoke lever 14 and the connecting portion between the yoke lever 14 and the movable cover member 15) is in a constant (rotating) state (that is, the lever assembly). Since the entire R is maintained constant (in a straight line in this embodiment), the individual lever assemblies R can be stably applied without variation (the quality of the coating is stable). Further, since a predetermined part of the lever assembly R (the wiping surface G side of the lever assembly R) is masked by the masking holding member 31, no masking tape or the like is required separately, and the lever non-coating portion ( It is possible to paint while providing the wiping surface G side of the lever assembly R.

(2)マスキング保持部材31にてレバーアッセンブリRの払拭面G側(の全体)がマスキングされるため、レバーアッセンブリRは非払拭面側からのみ塗装される。このようにすると、例えば、使用する塗料の量を低減できたり、吹き付け方向の角度を小さくできることから、ワイパ10のレバーアッセンブリRを安価に塗装することができる。又、払拭面G側(車両室内側)は特に車両の外部からは見え難いため、美観を大幅に悪化させることはない。即ち、美観を大幅に悪化させることなく、レバーアッセンブリRの低コスト化を図ることができる。   (2) Since the wiping surface G side (the whole) of the lever assembly R is masked by the masking holding member 31, the lever assembly R is coated only from the non-wiping surface side. If it does in this way, since the quantity of the coating material to be used can be reduced or the angle of a spraying direction can be made small, the lever assembly R of the wiper 10 can be painted cheaply. Further, since the wiping surface G side (vehicle interior side) is difficult to see especially from the outside of the vehicle, the aesthetic appearance is not greatly deteriorated. That is, the cost of the lever assembly R can be reduced without greatly deteriorating the aesthetic appearance.

(3)マスキング保持部材31にてレバーアッセンブリRにおけるブレードラバー16を把持するための複数の把持爪14a,15bが一直線状に維持されてレバー回動部が一定の状態、すなわち、レバーアッセンブリR全体が一定(本実施形態では一直線状)の塗装姿勢に維持されるため、その状態で塗装することで、レバーアッセンブリRを美しい仕上がりとすることができる。又、例えば、複数の把持爪14a,15bを一直線状に維持する構成は簡単な構成でよいため、マスキング保持部材31を簡単な構成とすることができる。   (3) The plurality of gripping claws 14a and 15b for gripping the blade rubber 16 in the lever assembly R by the masking holding member 31 are maintained in a straight line and the lever rotating portion is constant, that is, the entire lever assembly R Is maintained in a constant (in this embodiment, a straight line) coating posture, and the lever assembly R can have a beautiful finish by painting in that state. Further, for example, since the configuration for maintaining the plurality of gripping claws 14a and 15b in a straight line may be a simple configuration, the masking holding member 31 can be configured in a simple manner.

上記実施形態は、以下のように変更してもよい。
・上記実施形態のマスキング保持部材31は、複数の把持爪14a,15bがマスキング収容溝31aに挿入されるようにレバーアッセンブリRが載置されると、複数の把持爪14a,15bを一直線状に維持するものとしたが、図5に示すように、把持爪14a(15b)にて把持される被把持部としての被把持部材61を備えたものとしてもよい。
The above embodiment may be modified as follows.
In the masking holding member 31 of the above embodiment, when the lever assembly R is placed so that the plurality of gripping claws 14a and 15b are inserted into the masking receiving groove 31a, the plurality of gripping claws 14a and 15b are aligned in a straight line. However, as shown in FIG. 5, a gripped member 61 as a gripped portion gripped by the gripping claws 14 a (15 b) may be provided.

詳しくは、この例のマスキング収容溝31aの底部には、前記把持爪14a,15bと対応した長手方向の位置に把持爪14a,15bにて把持可能な被把持部材61が固定されている。そして、複数の把持爪14a,15bを(レバーアッセンブリRの)長手方向にスライド移動させることで把持爪14a,15bに被把持部材61を把持させることで、複数の把持爪14a,15bを一直線状に維持して払拭面直交方向(上下方向)に移動不能とさせるようにしてもよい。このようにすると、複数の把持爪14a,15bが一直線状の状態を強固に保持することができる。これにより、例えば、レバーアッセンブリRにおける払拭面G側(把持爪14a,15b側)を上方に配置して、言い換えると非払拭面側を下方に配置して、転写フィルムを液面に浮かべた水槽などに浸してレバーアッセンブリRの非払拭面側表面に転写する水圧転写等の塗装(含む印刷)が可能となる。即ち、上記実施形態では、塗装は、吹き付け塗装を採用したが、この例では、水圧転写を採用してもよい。又、勿論、吹き付け塗装や水圧転写以外の他の塗装(含む印刷)を採用してもよい。   Specifically, a gripped member 61 that can be gripped by the gripping claws 14a and 15b is fixed to the bottom of the masking receiving groove 31a of this example at a longitudinal position corresponding to the gripping claws 14a and 15b. The plurality of gripping claws 14a and 15b are linearly moved by causing the gripping claws 14a and 15b to grip the gripped member 61 by sliding the gripping claws 14a and 15b in the longitudinal direction (of the lever assembly R). The wiping surface may be made immovable in the direction perpendicular to the wiping surface (up and down direction). If it does in this way, a plurality of grasping claws 14a and 15b can hold firmly in the state of a straight line. Thereby, for example, the wiping surface G side (the gripping claws 14a, 15b side) of the lever assembly R is arranged upward, in other words, the non-wiping surface side is arranged downward, and the water tank in which the transfer film is floated on the liquid surface It is possible to perform coating (including printing) such as water pressure transfer that is immersed in the lever assembly R and transferred to the non-wiping surface side surface of the lever assembly R. That is, in the above embodiment, spray coating is employed as the coating, but in this example, hydraulic transfer may be employed. Of course, other coatings (including printing) other than spray coating or hydraulic transfer may be employed.

・上記実施形態では、メインレバー13と、2つのヨークレバー14と、2つの可動カバー部材15とを有したワイパ10のレバーアッセンブリRに対するレバーアッセンブリ塗装装置としたが、勿論、他の構成のレバーアッセンブリに対応したレバーアッセンブリ塗装装置としてもよい。言い換えると、上記実施形態では、レバー回動部がメインレバー13とヨークレバー14との連結部分、及びヨークレバー14と可動カバー部材15の連結部分であるレバーアッセンブリRに対するレバーアッセンブリ塗装装置としたが、異なる構成のレバー回動部を有するワイパのレバーアッセンブリに対応したレバーアッセンブリ塗装装置としてもよい。   In the above embodiment, the lever assembly coating device for the lever assembly R of the wiper 10 having the main lever 13, the two yoke levers 14, and the two movable cover members 15 is used. It is good also as a lever assembly coating device corresponding to an assembly. In other words, in the above embodiment, the lever rotating portion is a lever assembly coating apparatus for the lever assembly R, which is the connecting portion between the main lever 13 and the yoke lever 14 and the connecting portion between the yoke lever 14 and the movable cover member 15. Also, a lever assembly coating apparatus corresponding to a lever assembly of a wiper having a lever rotating portion having a different configuration may be used.

・上記実施形態では、マスキング保持部材31は、レバーアッセンブリRの払拭面G側(の全体)をマスキングするものとしたが、これに限定されず、レバー回動部を一定の状態に維持しながらレバーアッセンブリの払拭面G側(の全体)以外の部分をマスキングするものとしてもよい。   In the above embodiment, the masking holding member 31 masks the wiping surface G side (the whole) of the lever assembly R. However, the present invention is not limited to this, while maintaining the lever rotating portion in a constant state. It is good also as what masks parts other than the wiping surface G side (the whole) of a lever assembly.

・上記実施形態では、マスキング保持部材31は、レバーアッセンブリRにおける複数の把持爪14a,15bを一直線状に維持するものとしたが、これに限定されず、複数の把持爪14a,15bが一直線状とならないように(一直線状に並ばないように)しながらその状態を維持するものとしてもよい。   In the above embodiment, the masking holding member 31 maintains the plurality of gripping claws 14a and 15b in the lever assembly R in a straight line, but is not limited to this, and the plurality of gripping claws 14a and 15b are in a straight line shape. It is good also as what maintains the state, so that it may not become (it does not line up in a straight line).
