　塗装ラインには複数の静電粉体塗装用ハンガーが順次吊下され処理されていくが、より多くの被処理物をいちどに処理するために、静電粉体塗装用ハンガーには多数の被処理物を吊下できるようになっている（たとえば特許文献１参照）。 A plurality of electrostatic powder coating hangers are sequentially suspended and processed in the coating line, but in order to process more objects to be processed at once, many electrostatic powder coating hangers are processed. An object can be suspended (for example, see Patent Document 1).
　静電粉体塗装用ハンガーは、たとえば図１１（ａ）に示すように、門形のハンガー枠１０１と、そのハンガー枠１０１の２本の縦枠に架設された複数の取付桟体１０３、１０３、・・・とを有したハンガー体を備えている。それぞれの取付桟体１０３には被処理物Ｗを吊下支持する複数の支持体１０５（吊下クリップ１０５ｂ）、１０５、・・・が取り付けられている。 For example, as shown in FIG. 11A, the electrostatic powder coating hanger has a portal hanger frame 101 and a plurality of mounting bars 103, 103 installed on two vertical frames of the hanger frame 101. ,... Are provided. A plurality of support bodies 105 (suspending clips 105b), 105,... That suspend and support the workpiece W are attached to the respective mounting bars 103.
　この支持体１０５の取付構造として、たとえば図１１（ｂ）に示すように、吊下クリップ１０５ｂが取付桟体１０３の下端に溶接で取り付けられたものが一般に知られている。また、取付桟体１０３が金属板の重合板体にて形成され、それらの重合板体の間に、図１１（ｃ）に示すように、２つの吊下クリップ１０５ｂ、１０５ｂを有した支持体１０５の連結部１０５ａを挟持固定あるいは溶接固定する構造とすることも想定できる。 For example, as shown in FIG. 11 (b), an attachment structure of the support 105 is generally known in which a hanging clip 105 b is attached to the lower end of the attachment bar 103 by welding. Further, the mounting bar 103 is formed of a superposed plate of metal plates, and a support having two hanging clips 105b and 105b between the superposed plates as shown in FIG. 11 (c). It is also possible to assume a structure in which 105 connecting portions 105a are clamped and fixed by welding.

　ところで、このような静電粉体塗装用ハンガー１００を用いて静電粉体塗装を行う場合、繰り返し使用により静電粉体塗装用ハンガー１００の各部の表面に塗装膜が形成されるが、塗装膜による通電不良になると塗装不良が発生するおそれがあるため、それを防止する対策として通例では定期的に塗装膜の剥離処理が行われる。特に、取付桟体１０３と支持体１０５の接触部および支持体１０５と被処理物Ｗの接触部は被処理物Ｗへの通電を確実にするために、塗装膜が残らないように剥離する必要がある。 By the way, when electrostatic powder coating is performed using such an electrostatic powder coating hanger 100, a coating film is formed on the surface of each part of the electrostatic powder coating hanger 100 by repeated use. Since a coating failure may occur when a current-carrying failure is caused by a film, the coating film is regularly peeled off as a countermeasure to prevent it. In particular, the contact portion between the mounting bar 103 and the support member 105 and the contact portion between the support member 105 and the workpiece W need to be peeled off so as not to leave a coating film in order to ensure energization of the workpiece W. There is.
　剥離方法としては通例、燃焼により塗装膜を焼き切る方法、薬品に浸して塗装膜を取り除く方法、金属破片をぶつけて塗装膜を物理的に落とす方法（ショットブラスト法）が実施されている。ただし近時では、環境問題の観点から、ショットブラスト法が多く実施されている。 As a peeling method, a method of burning off the coating film by combustion, a method of removing the coating film by immersing in chemicals, and a method of physically dropping the coating film by hitting a metal piece (shot blasting method) are carried out. Recently, however, many shot blasting methods have been implemented from the viewpoint of environmental problems.
　しかしながら、図１１（ｂ）のものにおいてショットブラスト法を実施した場合、吊下クリップ１０５ｂが破損することがあった。吊下クリップ１０５ｂの先端は種々の被処理物を引っ掛けて吊下するため、先端が破損すると、その吊下クリップ１０５ｂが使えなくなる場合がある。また、ショットブラスト法を何度も繰り返すうちに、吊下クリップ１０５ｂが溶接固定した箇所から外れてしまうこともある。 However, when the shot blasting method is performed in the case of FIG. 11B, the hanging clip 105b may be damaged. Since the tip of the hanging clip 105b is hung by hanging various objects to be processed, if the tip is damaged, the hanging clip 105b may become unusable. Further, as the shot blasting method is repeated many times, the hanging clip 105b may come off from the place where the welding clip is fixed.
　このように吊下クリップ１０５ｂが破損した場合、新しい吊下クリップ１０５ｂを溶接にて補修取り付けすればよいが、高度な技能を有した者でないと修理工数がかかってしまい効率的に補修処理を行えない。また、一部の吊下クリップ１０５ｂが欠けた状態の静電粉体塗装用ハンガー１００を利用することはできるが、そのような使い方では、吊下クリップ１０５ｂへの被処理物Ｗの吊下数が減少するため生産性は当然に低下する。 When the hanging clip 105b is damaged in this way, a new hanging clip 105b may be repaired and attached by welding. However, if the person does not have a high level of skill, the repair man-hours will be required and the repair process can be performed efficiently. Absent. In addition, the electrostatic powder coating hanger 100 in which some of the hanging clips 105b are missing can be used, but in such a usage, the number of objects to be processed W suspended on the hanging clips 105b. As a result, productivity is naturally reduced.
　一方、図１１（ｃ）のものは、取付桟体１０３と支持体１０５との接触部が重合板体の内部に隠れているため、その部位に塗装膜が形成されるおそれは少ない。また、吊下クリップ１０５ｂが破損した場合でも、支持体１０５が挟持により取り付けてあるため、取り替えは比較的容易に行えるというメリットもある。 On the other hand, in the case of FIG. 11C, since the contact portion between the mounting bar 103 and the support 105 is hidden inside the polymer plate, there is little possibility that a coating film is formed at that portion. Further, even when the hanging clip 105b is damaged, the support 105 is attached by clamping, so that there is an advantage that the replacement can be performed relatively easily.
　しかしながら、このものでも取付桟体１０３の重合板体の内部に粉体が入り込むおそれがあり、その結果、重合板体内部に塗装膜が形成されるおそれもある。そのような内部の塗装膜は当然にショットブラスト法では剥離することはできず、燃焼や薬品による剥離方法を採らなければならないが、それらの方法を採ったとしても、重合板体内部の剥離が確実になされたかどうかを視認することはきわめて困難である。 However, even in this case, there is a possibility that powder enters the inside of the polymer plate of the mounting bar 103, and as a result, a coating film may be formed inside the polymer plate. Naturally, such an internal coating film cannot be peeled off by the shot blasting method, and it is necessary to adopt a peeling method by combustion or chemicals, but even if those methods are adopted, peeling inside the polymer plate body is not possible. It is very difficult to see if it has been done reliably.
　また、図１１（ｃ）のものは、支持体１０５の上部（連結部１０５ａ）を重合板体内部に収容する構造であるため、図例のように取付桟体１０３の幅寸法を大きくせざるを得ず、コンパクトに形成できないというデメリットもある。 11C has a structure in which the upper portion of the support 105 (the connecting portion 105a) is accommodated inside the superposition plate, and therefore, the width dimension of the mounting bar 103 need not be increased as shown in the figure. There is also a demerit that it cannot be made compact.
　本発明は、上記の種々の問題を考慮して提案されたもので、その目的は、取付桟体等を含むハンガー体に付着した塗装膜の剥離が確実に行え、かつ支持体の取り替えが簡単に行える利便性の高い静電粉体塗装用ハンガーを提供することにある。 The present invention has been proposed in consideration of the above-mentioned various problems, and its purpose is to reliably remove the coating film adhered to the hanger body including the mounting bar and the like and to easily replace the support body.

　また、この静電粉体塗装用ハンガーは支持体を取付桟体の外面の係止部に対して取り付けする構成であり、支持体上部を隠すように挟み込んだり、支持体上部を取付桟体に固着したりして固定する構成ではないため、取付桟体を幅広に形成する必要がなく、静電粉体塗装用ハンガーをコンパクトに形成することができる。 The electrostatic powder coating hanger has a structure in which the support is attached to the engaging portion of the outer surface of the mounting frame, and is sandwiched so as to hide the upper part of the support, or the upper part of the support is attached to the mounting bar. Since it is not the structure which adheres and fixes, it is not necessary to form the attachment crosspiece | frame widely, and the hanger for electrostatic powder coating can be formed compactly.

　以下に、本発明の実施の形態について、添付図面を参照しながら説明する。 Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.
　まず、本発明の一実施形態に係る静電粉体塗装用ハンガーの各部について、図１～図６にもとづいて説明する。 First, each part of the electrostatic powder coating hanger according to one embodiment of the present invention will be described with reference to FIGS.
　この静電粉体塗装用ハンガー１０（以下、ハンガー１０と略す）は、被処理物Ｗを吊下支持した状態で塗装ライン（レール）（不図示）に吊下され、移動するレールにより静電塗装装置（不図示）に搬入され、静電塗装装置内では移動しながら静電塗装処理がなされ、処理終了後に静電塗装装置から搬出されるものである。 This electrostatic powder coating hanger 10 (hereinafter abbreviated as hanger 10) is suspended on a coating line (rail) (not shown) in a state where the workpiece W is suspended and supported by the moving rail. It is carried into a coating apparatus (not shown), is subjected to electrostatic coating processing while moving in the electrostatic coating apparatus, and is carried out of the electrostatic coating apparatus after the processing is completed.
　ハンガー１０は、門形のハンガー枠１１と、そのハンガー枠１１の２本の縦枠１１ｂ、１１ｂに架設された複数の取付桟体１３、１３、・・・とを有したハンガー体１０Ａを備えるとともに、それぞれの取付桟体１３には複数の支持体２０、２０、・・・が着脱自在に吊下できる構成となっている。ハンガー体１０Ａの各部および支持体２０、２０、・・・は通電可能なように通電部材を素材としている。 The hanger 10 includes a hanger body 10A having a gate-shaped hanger frame 11 and a plurality of attachment bars 13, 13,... Installed on the two vertical frames 11b, 11b of the hanger frame 11. In addition, a plurality of support bodies 20, 20,... Can be detachably suspended from each mounting bar 13. Each part of the hanger body 10A and the support bodies 20, 20,... Are made of an energizing member so that energization is possible.
　ハンガー枠１１は、外郭を構成する枠体であり、レールより通電を受ける通電用フック部１２が一体に形成された上枠１１ａと、上枠１１ａの両端から下方に延びた縦枠１１ｂ、１１ｂとよりなる。 The hanger frame 11 is a frame constituting an outer shell, and includes an upper frame 11a integrally formed with an energization hook portion 12 that receives power from a rail, and vertical frames 11b and 11b extending downward from both ends of the upper frame 11a. And more.
　また、両縦枠１１ｂ、１１ｂには上下方向に所定の間隔をおいて１または複数（図例では３本）の取付桟体１３、１３が架設されている。なお、取付桟体１３はハンガー枠１１と一体成形されたものでもよいし、別体として取り付けられるものでもよい。 In addition, one or a plurality of (three in the illustrated example) mounting bars 13 and 13 are installed on both vertical frames 11b and 11b at a predetermined interval in the vertical direction. The attachment bar 13 may be integrally formed with the hanger frame 11 or may be attached as a separate body.
　この取付桟体１３は、角柱材または角筒材よりなり、その前面には等間隔に係止凸部１４、１４、・・・が突設されており、その係止凸部１４に支持体２０が取り外し可能に弾性係止されている。 The mounting bar 13 is made of a prismatic or square tube material, and has locking projections 14, 14,... Projecting from the front surface at equal intervals. 20 is detachably elastically locked.
　係止凸部１４は、支持体２０が係止される柱状体の首部１４ａと、首部１４ａよりも径大とした頭部１４ｂとを有した形状となっている。このような係止凸部１４は、図１（ｂ）（ｃ）に示すように、取付桟体１３に開設した孔１３ａにリベットＲをかしめ止めすることで形成すればよい。 The locking convex portion 14 has a columnar body neck portion 14a to which the support body 20 is locked, and a head portion 14b having a diameter larger than that of the neck portion 14a. Such a locking projection 14 may be formed by caulking the rivet R in the hole 13a opened in the mounting bar 13, as shown in FIGS.
　また、係止凸部１４の首部１４ａの高さＬは、支持体２０を一定に係止するために略一定の寸法となっている。図１（ｂ）（ｃ）に示すように、かしめ部Ｒ１がその先端部Ｒ１ｂよりも基端部Ｒ１ａを径大として、その径大の基端部Ｒ１ａを孔１３ａに挿入できないようにしてかしめ止めすれば、一定の高さＬの首部１４ａを形成することができる。 Further, the height L of the neck portion 14a of the locking projection 14 has a substantially constant dimension in order to lock the support body 20 uniformly. As shown in FIGS. 1B and 1C, the caulking portion R1 has a base end portion R1a larger in diameter than the distal end portion R1b, and the caulking portion R1 cannot be inserted into the hole 13a. If it stops, the neck part 14a of the fixed height L can be formed.
　一方、支持体２０は、棒状体より一体に形成され、両側端に配された吊下クリップ２２、２２と、吊下クリップ２２の上部間をつなぐ連結部２１とを備えて、正面視で略門形をなしている。 On the other hand, the support body 20 is formed integrally with a rod-shaped body, and includes suspension clips 22 and 22 disposed on both side ends, and a connecting portion 21 that connects between upper portions of the suspension clips 22, and is substantially in front view. It has a gate shape.
　吊下クリップ２２は、塗装対象である被処理物Ｗ（本例では樋受金具）を吊下する部位であり、脚部２２ａと、その下端に斜め上向きに延出した針状のフック２２ｂとを有した形状となっている。そして、その脚部２２ａ、２２ａの上部には相互に凸部が向かい合うように湾曲状に形成された、係止凸部１４、１４に固定するための係止凹部２２ｃ、２２ｃ（被係止部）が形成されている。 The hanging clip 22 is a part that suspends the workpiece W to be painted (in this example, a hook metal fitting), and includes a leg portion 22a and a needle-like hook 22b that extends obliquely upward at the lower end thereof. It has a shape with. The upper portions of the leg portions 22a, 22a are formed in a curved shape so that the convex portions face each other, and the locking concave portions 22c, 22c (fixed portions) for fixing to the locking convex portions 14, 14. ) Is formed.
　なお、図２の支持体２０は両フック２２ｂ、２２ｂが同一方向を向いているが、反対方向を向いていてもよい。 In addition, although both the hooks 22b and 22b have faced the same direction, the support body 20 of FIG. 2 may face the opposite direction.
　この支持体２０は、図２（ａ）に示すように、１組の吊下クリップ２２、２２が相互に近接、離反するように変形するように弾性を有している。そのように吊下クリップ２２、２２間を狭めた状態で、支持体２０は取付桟体１３に設けた２つの係止凸部１４、１４に上方あるいは前方より嵌め入れられ、係止凹部２２ｃが係止凸部１４の首部１４ａに係止されて、上下方向に移動できないようになる（図２（ａ）～（ｄ）参照）。 The support 20 has elasticity so that the pair of hanging clips 22 and 22 are deformed so as to approach and separate from each other, as shown in FIG. In such a state that the space between the hanging clips 22 and 22 is narrowed, the support body 20 is fitted into the two locking projections 14 and 14 provided on the mounting bar 13 from above or from the front, and the locking recess 22c is formed. It is locked to the neck 14a of the locking projection 14 so that it cannot move in the vertical direction (see FIGS. 2A to 2D).
　さらに、支持体２０を取り付けた後、２つの吊下クリップ２２、２２の脚部２２ａ、２２ａは、図２（ｄ）に白抜き矢印で示すように弾発力が作用するので、それらの弾発力と、係止凸部１４と係止凹部２２ｃとの係止とがあいまって、支持体２０はずれることなく取付桟体１３に固定される。なお、他の各図においても、吊下クリップ２２、２２等の弾発力の作用する方向を白抜き矢印で示している。 Further, after attaching the support 20, the leg portions 22a and 22a of the two hanging clips 22 and 22 are subjected to elastic force as shown by the white arrows in FIG. The support 20 is fixed to the mounting bar 13 without slipping due to the combination of the generated force and the locking of the locking projection 14 and the locking recess 22c. In each of the other drawings, the direction in which the elastic force of the hanging clips 22 and 22 acts is indicated by a white arrow.
　このように、支持体２０は２つの係止凸部１４、１４に架設状態に弾性係止されるので、いったん取り付けられると、被処理物Ｗを吊下した状態でも支持体２０のずれや外れは発生しない。 Thus, since the support body 20 is elastically locked to the two locking projections 14 and 14 in a erected state, once attached, the support body 20 is displaced or disengaged even when the workpiece W is suspended. Does not occur.
　さらに、係止凸部１４には首部１４ａより径大な頭部１４ｂが形成されているため、支持体２０の前方への脱落も防止できる。また、首部１４ａを、吊下クリップ２２が取付桟体１３と頭部１４ｂとの間に抜け出ないような高さ寸法とすることが望ましい。 Furthermore, since the head 14b having a diameter larger than that of the neck 14a is formed on the locking convex portion 14, it is possible to prevent the support 20 from dropping off to the front. Further, it is desirable that the neck portion 14a has such a height dimension that the hanging clip 22 does not come out between the mounting bar 13 and the head portion 14b.
　以上のようにして取り付けされた支持体２０は、図２（ｄ）に示すように、連結部２１が取付桟体１３よりも上方に突出した状態となる。 As shown in FIG. 2 (d), the support 20 attached as described above is in a state in which the connecting portion 21 protrudes upward from the attachment bar 13.
　このように、支持体２０の係止凹部２２ｃが取付桟体１３に設けた係止凸部１４に係止される構造であるため、支持体２０の連結部２１等を取付桟体１３に溶接等で固着させなくてもよく、取付桟体１３として幅寸法の小さなものを利用できる。 As described above, since the locking recess 22c of the support 20 is locked to the locking projection 14 provided on the mounting bar 13, the connecting portion 21 and the like of the support 20 are welded to the mounting bar 13. It is not necessary to fix it with the like, and a small width dimension can be used as the mounting bar 13.
　取付桟体１３の幅寸法を小さくできるから、ハンガー１０の上下方向の寸法を小さくでき、多くの取付桟体１３を設けることができ、そのため多くの支持体２０を取り付けて、より多くの被処理物Ｗを同時処理することができる。 Since the width dimension of the mounting bar 13 can be reduced, the vertical dimension of the hanger 10 can be reduced, so that a large number of mounting bars 13 can be provided. The object W can be processed simultaneously.
　また、支持体２０が取り外し可能に取付桟体１３に取り付けてあるため、塗装膜の剥離をショットブラスト法により行う際には、支持体２０を外した状態で行えば、ハンガー枠１１や取付桟体１３の一部に塗装膜が残ることなく塗装膜の剥離を確実に行うことができる。また、取り外した支持体２０は、薬品により塗装膜を剥離することができる。 In addition, since the support 20 is detachably attached to the mounting frame 13, when the coating film is peeled off by the shot blasting method, if the support 20 is removed, the hanger frame 11 and the mounting frame are removed. The coating film can be surely peeled without leaving the coating film on a part of the body 13. Moreover, the removed support body 20 can peel a coating film with a chemical | medical agent.
　さらに、支持体２０は取付桟体１３の外面の係止凸部１４に取り外し可能に弾性係止される構成であるため、支持体２０を取り付けた状態でショットブラスト法による剥離を実施して、かりに支持体２０が破損した場合でも、その部位に対して取り替えすればよい。つまり、支持体２０が歯抜け状態にはならないように支持体２０を補充でき、生産性の高い塗装処理を行える。 Furthermore, since the support 20 is configured to be elastically removably locked to the locking projection 14 on the outer surface of the mounting bar 13, the peeling by the shot blast method is performed with the support 20 attached, Even if the support body 20 is damaged, the part may be replaced. That is, the support body 20 can be replenished so that the support body 20 does not fall out of teeth, and a highly productive coating process can be performed.
　また、支持体２０が被処理物Ｗを吊下支持する２つの吊下クリップ２２、２２を備えた一体形状であるため、支持体２０の取り付け、取り外しを迅速に効率的に行える。 In addition, since the support body 20 has an integral shape including the two suspension clips 22 and 22 for supporting the workpiece W in a suspended manner, the support body 20 can be attached and detached quickly and efficiently.
　支持体２０が複数の吊下クリップ２２、２２を備えた例として、たとえば図３（ａ）のように、吊下クリップ２２、２２間の距離が長いものも挙げられる。 As an example in which the support 20 includes a plurality of hanging clips 22 and 22, a long distance between the hanging clips 22 and 22, for example, as shown in FIG.
　このような支持体２０を取り付け、両吊下クリップ２２、２２間に位置する係止凸部１４には支持体２０を取り付けないようにすれば、横幅寸法の大きな被処理物Ｗを、隣接する吊下クリップ２２がじゃまになることなく吊下させることができる。 If such a support body 20 is attached, and the support body 20 is not attached to the latching convex portion 14 located between the two suspended clips 22, 22, the workpiece W having a large lateral width is adjacent. The hanging clip 22 can be hung without being obstructed.
　また、図３（ｂ）に示すように、１組の吊下クリップ２２、２２間にさらなる吊下クリップ２２、２２を配した支持体２０を用いてもよい。この支持体２０は、両端の吊下クリップ２２、２２間の吊下クリップ２２、２２は係止凸部１４に係止されるようにはなっておらず、両端の吊下クリップ２２、２２のみに係止凹部２２ｃ、２２ｃが形成され、それらの係止凹部２２ｃ、２２ｃが係止凸部１４、１４に係止される構成となっている。もちろん、両端の１組の吊下クリップ２２、２２に加えてさらに他の吊下クリップ２２も係止される構成としてもよい。 Further, as shown in FIG. 3B, a support body 20 in which further hanging clips 22 and 22 are arranged between a pair of hanging clips 22 and 22 may be used. In this support 20, the hanging clips 22, 22 between the hanging clips 22, 22 at both ends are not locked to the locking projections 14, but only the hanging clips 22, 22 at both ends. The locking recesses 22c, 22c are formed in the locking recesses 22c, 22c, and the locking projections 14, 14 are locked. Of course, in addition to one set of hanging clips 22 and 22 at both ends, another hanging clip 22 may be locked.
　このような支持体２０を用いれば、３つ以上の吊下クリップ２２が一体として製造できるので支持体２０の製造コストを低減できる。また、係止凸部１４も少なくすることができるので、ハンガー１０全体の製造コストをさらに低減できる。さらに、支持体２０の取り付け、取り外しを迅速かつ効率的に行うこともできる。 If such a support body 20 is used, three or more hanging clips 22 can be manufactured as one body, so that the manufacturing cost of the support body 20 can be reduced. Moreover, since the latching convex part 14 can also be decreased, the manufacturing cost of the hanger 10 whole can further be reduced. Furthermore, the support 20 can be attached and detached quickly and efficiently.
　図２、図３の例は、支持体２０の吊下クリップ２２、２２を２つの係止凸部１４、１４の内側に挟み込む構造となっているが、図４（ａ）（ｂ）に示すように、支持体２０が吊下クリップ２２、２２が２つの係止凸部１４、１４を外側より挟み込むように架設されるものでもよい。 2 and 3 have a structure in which the hanging clips 22 and 22 of the support 20 are sandwiched between the two locking projections 14 and 14, as shown in FIGS. 4 (a) and 4 (b). Thus, the support body 20 may be constructed so that the hanging clips 22 and 22 sandwich the two locking projections 14 and 14 from the outside.
　この支持体２０は、各吊下クリップ２２、２２の外側に凸部が突出するように係止凹部２２ｃ、２２ｃが各吊下クリップ２２、２２の内側上部に形成されている。 The support 20 has locking recesses 22c and 22c formed on the inner upper portions of the suspension clips 22 and 22 so that the projections protrude outside the suspension clips 22 and 22, respectively.
　この支持体２０は、吊下クリップ２２、２２を相互に離反する方向に弾性変形させた状態で、係止凹部２２ｃ、２２ｃを係止凸部１４、１４に弾性係止させて、上方より取り付けすることができる（図４（ｂ）参照）。 The support 20 is attached from above by elastically locking the locking recesses 22c and 22c with the locking protrusions 14 and 14 in a state in which the hanging clips 22 and 22 are elastically deformed in directions away from each other. (See FIG. 4B).
　支持体２０を係止凸部１４、１４に取り付けた状態では、支持体２０の係止凹部２２ｃ、２２ｃが係止凸部１４、１４により係止され、さらに図４（ｂ）の矢印で示すように弾発力が作用するため、支持体２０はしっかりと固定される。 In a state where the support 20 is attached to the locking projections 14, 14, the locking recesses 22 c, 22 c of the support 20 are locked by the locking projections 14, 14, and are further indicated by arrows in FIG. Thus, since the elastic force acts, the support body 20 is firmly fixed.
　この支持体２０は、係止凹部２２ｃ、２２ｃが吊下クリップ２２、２２の基端部（連結部２１から脚部２２ａへ折曲した部位）に形成されている形状であるため、連結部２１の取付桟体１３から上方への突出がなく、すっきりした外観とすることができ、支持体２０の材料コストを低減化することもできる。 The support 20 has a shape in which the locking recesses 22c and 22c are formed at the base ends of the suspension clips 22 and 22 (parts bent from the connecting portion 21 to the leg portion 22a). Thus, there is no upward protrusion from the mounting bar 13, and a clean appearance can be obtained, and the material cost of the support 20 can be reduced.
　さらに、図５（ａ）（ｂ）に示すように、１つの係止凸部１４に、２つの吊下クリップ２２、２２を有した支持体２０を取り付けるようにしてもよい。 Further, as shown in FIGS. 5 (a) and 5 (b), a support body 20 having two hanging clips 22, 22 may be attached to one locking convex portion 14.
　この支持体２０は、複数の係止凸部１４、１４に架設するための架橋状の連結部２１（図２等参照）を備えておらず、２つの吊下クリップ２２、２２がヘアピン状に連結され、その連結部２１より二股状に延びた吊下クリップ２２、２２の脚部２２ａ、２２ａの上端が湾曲して係止凹部２２ｃが形成され、その直下には吊下クリップ２２、２２間が狭まったネック部２２ｄが形成され、相互に離反した下端には斜め上向きの針状のフック２２ｂ、２２ｂが相反する方向に突出するように形成されている。 The support 20 does not include a bridging connecting portion 21 (see FIG. 2 and the like) for laying on the plurality of locking projections 14 and 14, and the two hanging clips 22 and 22 are in a hairpin shape. The upper ends of the leg portions 22a and 22a of the hanging clip 22 and 22 that are connected and extend in a forked shape from the connecting portion 21 are curved to form a locking recess 22c. A narrow neck portion 22d is formed, and obliquely upward needle- like hooks 22b, 22b are formed so as to protrude in opposite directions at the lower ends separated from each other.
　この支持体２０は、図５（ｂ）の右側に示すように、支持体２０を係止凸部１４の上方より矢印のように嵌め入れれば、係止凹部２２ｃが係止凸部１４の首部１４ａに弾性係止される。 As shown in the right side of FIG. 5 (b), when the support 20 is fitted as indicated by an arrow from above the locking projection 14, the locking recess 22 c becomes the neck of the locking projection 14. It is elastically locked to 14a.
　このような支持体２０によれば、架橋状の連結部２１を備えなくてもよく、２つの吊下クリップ２２、２２を有した支持体２０を少ない材料で形成でき、製造コストを低減することができる。 According to such a support body 20, it is not necessary to provide the bridging connection portion 21, and the support body 20 having the two hanging clips 22, 22 can be formed with a small amount of material, thereby reducing manufacturing costs. Can do.
　また、図５（ｃ）に示すように、１つの係止凹部２２ｃに対して１つの吊下クリップ２２を有した支持体２０を、係止凸部１４に対する弾性係止によって取り付けるようにしてもよい。 Further, as shown in FIG. 5C, the support body 20 having one hanging clip 22 with respect to one locking recess 22 c may be attached by elastic locking with respect to the locking projection 14. Good.
　ついで、係止凸部１４を取付桟体１３の前後両外面に設けた例について、図６を参照しながら説明する。 Next, an example in which the locking projections 14 are provided on both front and rear outer surfaces of the mounting bar 13 will be described with reference to FIG.
　図６（ａ）（ｂ）のものは、前外面の係止凸部１４と後外面の係止凸部１４とが交互に異なる位置に形成されており、それに応じて支持体２０、２０は両面でずれた位置に取り付けられるようになっている。 6 (a) and 6 (b), the engaging projections 14 on the front outer surface and the engaging projections 14 on the rear outer surface are alternately formed at different positions. It is designed to be attached at a position shifted on both sides.
　この例で使用する支持体２０は、フック２２ｂが前方または後方に突出するように形成されており、そのためハンガー１０の前後両外面に被処理物Ｗを吊下できるようになっている。 The support 20 used in this example is formed so that the hook 22b protrudes forward or backward, and thus the workpiece W can be suspended from both front and rear outer surfaces of the hanger 10.
　なお、係止凸部１４は前後外面で同位置に設けてもよいが、前後外面で同一形状の支持体２０を用いる場合、塗装効率を向上させるためには、図６（ａ）の例のように異なる位置に設けることが望ましい。 In addition, although the latching convex part 14 may be provided in the same position on the front and rear outer surfaces, in the case of using the support 20 having the same shape on the front and rear outer surfaces, in order to improve the coating efficiency, the example of FIG. It is desirable to provide at different positions.
　また、図６（ｃ）（ｄ）のものは、前外面の係止凸部１４と後外面の係止凸部１４とが正面視で同位置に形成されており、前後で吊下クリップ２２、２２の長さの異なる支持体２０、２０が取り付けられている。 6 (c) and 6 (d), the locking projection 14 on the front outer surface and the locking projection 14 on the rear outer surface are formed at the same position when viewed from the front, and the hanging clip 22 is front and rear. , 22 are attached to supports 20 and 20 having different lengths.
　このように吊下クリップ２２、２２の長さが異なる支持体２０、２０を前後に取り付ければ、被処理物Ｗを異なる高さ位置に吊下できるので、前後外面両側からの塗装を効率的に行うことができる。 Thus, if the support bodies 20 and 20 in which the lengths of the suspension clips 22 and 22 are different are attached to the front and rear, the workpiece W can be suspended at different height positions, so that painting from both sides of the front and rear outer surfaces can be efficiently performed. It can be carried out.
　このように係止凸部１４、１４を取付桟体１３の両外面に設けた構成によれば、１つのハンガー１０に、より多くの支持体２０、２０を設けることができ、塗装効率を高めることができる。 Thus, according to the structure which provided the latching convex parts 14 and 14 in both the outer surfaces of the attachment crosspiece 13, more support bodies 20 and 20 can be provided in one hanger 10, and coating efficiency is improved. be able to.
　以上の種々の実施形態では、支持体２０を弾性部材で形成し、係止凸部１４に取り付ける際に支持体２０の弾発力によって弾性係止されるものを示したが、係止凸部１４の弾発力で支持体２０を弾性係止する構造としてもよい。 In the various embodiments described above, the support 20 is formed of an elastic member and is elastically locked by the elastic force of the support 20 when attached to the locking protrusion 14. It is good also as a structure which elastically latches the support body 20 with the elastic force of 14.
　また、係止凸部１４を取付桟体１３の上下面のいずれかに設けて、それに支持体２０を係止するようにしてもよい。 Further, the locking projection 14 may be provided on either the upper or lower surface of the mounting bar 13 and the support 20 may be locked thereto.
　以上の実施形態では係止部を柱状体の係止凸部１４で構成したものを例示したが、そのような形状には限定されない。たとえば、図７～図１０に示すように取付桟体１３を様々な形状としてもよい。これらの図に示した支持体２０の係止構造は、支持体２０に係止凹部２２ｃ（図２等参照）を設けず、支持体２０の吊下クリップ２２、２２の脚部２２ａ、２２ａで係止部に係止されるようにしたものである。 In the above embodiment, the engaging portion is constituted by the locking protrusion 14 of the columnar body, but it is not limited to such a shape. For example, as shown in FIGS. 7 to 10, the mounting bar 13 may have various shapes. The locking structure of the support body 20 shown in these drawings does not include the locking recess 22c (see FIG. 2 and the like) in the support body 20, and the leg portions 22a and 22a of the hanging clips 22 and 22 of the support body 20 are used. It is configured to be locked to the locking portion.
　図７に示した取付桟体１３はその前面が凹凸形状となっている。すなわち、取付桟体１３には左右幅寸法の大きい複数の係止凸部１４、１４が設けられており、それらの間には上下に連通した凹溝１５が形成されている。 The front surface of the mounting bar 13 shown in FIG. That is, the mounting bar 13 is provided with a plurality of locking projections 14 and 14 having a large left-right width dimension, and a concave groove 15 communicating vertically is formed between them.
　支持体２０の２つの吊下クリップ２２、２２の脚部２２ａ、２２ａのそれぞれは係止凸部１４の両隣の凹溝１５、１５に挿通され、図７（ｃ）の例では、吊下クリップ２２、２２の脚部２２ａ、２２ａの弾発力が係止凸部１４を両側より締め付けるように作用する。また、図７（ｄ）の例では、吊下クリップ２２、２２の脚部２２ａ、２２ａの弾発力が各外側の係止凸部１４を押圧するように作用する。 Each of the leg portions 22a and 22a of the two suspension clips 22 and 22 of the support 20 is inserted into the concave grooves 15 and 15 on both sides of the locking projection 14, and in the example of FIG. The elastic force of the leg portions 22a and 22a acts to tighten the locking projection 14 from both sides. Moreover, in the example of FIG.7 (d), it acts so that the elastic force of the leg parts 22a and 22a of the suspension clips 22 and 22 may press the latching convex part 14 of each outer side.
　なお、これらの例では支持体２０の吊下クリップ２２には湾曲形状の係止凹部２２ｃが形成されておらず、吊下クリップ２２の脚部２２ａの適宜な部位を被係止部として係止されるようにすればよい。 In these examples, the hanging clip 22 of the support 20 is not formed with a curved locking recess 22c, and the appropriate portion of the leg portion 22a of the hanging clip 22 is locked as a locked portion. What should I do?
　このような係止構造によれば、湾曲形状の係止凹部２２ｃを支持体２０に設けなくてもよいため、支持体２０をシンプルな形状にすることができ、製造コストを低減することもできる。 According to such a locking structure, since the curved locking recess 22c does not have to be provided in the support body 20, the support body 20 can have a simple shape, and the manufacturing cost can be reduced. .
　また、図８に示した取付桟体１３は、図７と同様に取付桟体１３の前面に係止凸部１４と凹溝１５が交互に形成され、その凹溝１５に支持体２０の全体を嵌め入れる構成となっている。すなわち、図８（ｃ）に示すように、吊下クリップ２２、２２の脚部２２ａ、２２ａの弾発力が凹溝１５の両側に配された係止凸部１４、１４を押圧するように作用して、支持体２０が係止される。 Further, in the mounting bar 13 shown in FIG. 8, the locking projections 14 and the concave grooves 15 are alternately formed on the front surface of the mounting bar 13 as in FIG. 7, and the entire support 20 is formed in the concave grooves 15. Is configured to fit. That is, as shown in FIG. 8C, the elastic force of the leg portions 22a and 22a of the hanging clips 22 and 22 presses the locking convex portions 14 and 14 disposed on both sides of the concave groove 15. Acting, the support 20 is locked.
　このような係止構造によれば、図７のものと同様に、支持体２０をシンプルな形状にすることができる。また、支持体２０を凹溝１５に嵌め入れる構成であるから、凹溝１５の幅寸法を大きくする必要があり、そのため取付桟体１３の省材料化が図れる。 According to such a locking structure, the support body 20 can be made into a simple shape as in the case of FIG. Further, since the support body 20 is configured to be fitted into the concave groove 15, it is necessary to increase the width dimension of the concave groove 15, so that material saving of the mounting bar 13 can be achieved.
　また、図９に示したものは、取付桟体１３が、断面倒Ｌ字状の板体で形成されており、その上板部１３ｂには切り起こし形成により下方に垂下形成された垂下片１８が対設されている。垂下片１８は弾性を有し、切り起こしてできた凹状部１７の両端から垂下した両垂下片１８、１８は、下端が上端よりも相近接するように傾斜しており、それを略垂直状態とするように押圧するとそれに反発する弾発力が発生する構成となっている。 Further, in the structure shown in FIG. 9, the mounting bar 13 is formed of a plate body having an inverted L-shaped cross section, and a hanging piece 18 is formed by hanging down on the upper plate portion 13b. Is opposed. The drooping piece 18 has elasticity, and both drooping pieces 18 and 18 hung from both ends of the concave portion 17 formed by being cut and raised are inclined so that the lower ends are closer to each other than the upper end, When pressed in such a manner, a resilient force that repels it is generated.
　図９（ｃ）に示すように、支持体２０で凸状部１６よりなる係止部を挟み込むように支持体２０を取り付けると、垂下片１８の弾発力と支持体２０の吊下クリップ２２の弾発力との相互作用によって、支持体２０は強固に係止される。 As shown in FIG. 9C, when the support 20 is attached so that the support 20 sandwiches the engaging portion made of the convex portion 16, the elastic force of the hanging piece 18 and the hanging clip 22 of the support 20. Due to the interaction with the elastic force, the support 20 is firmly locked.
　このような係止構造によれば、支持体２０の強固な取り付けができるとともに、取付桟体１３を板体の切り起こしにより、簡易にかつ低コストで形成することができる。 According to such a locking structure, the support 20 can be firmly attached, and the mounting bar 13 can be formed easily and at low cost by cutting and raising the plate.
　なお、支持体２０を凸状部１６、１６間の凹状部１７に嵌め込んで係止されるようにしてもよい。 It should be noted that the support 20 may be fitted and locked in the concave portion 17 between the convex portions 16 and 16.
　また、図１０（ａ）～（ｃ）には、さらに他の例を示している。 Further, FIGS. 10A to 10C show still other examples.
　図１０（ａ）に示した取付桟体１３は、板体を交互に折り畳むように折り曲げて形成されており、その前後面には交互に凹凸が表れている。この係止凸部１４よりなる係止部を、図７（ｃ）と同様に、１対の吊下クリップ２２、２２で挟み込むようにして、支持体２０が取付桟体１３に係止されるようになっている。 The mounting bar 13 shown in FIG. 10 (a) is formed by bending so that the plate is alternately folded, and irregularities appear alternately on the front and back surfaces thereof. As shown in FIG. 7C, the support 20 is locked to the mounting bar 13 so as to be sandwiched between the pair of hanging clips 22, 22. It is like that.
　また、図１０（ｂ）に示した取付桟体１３は、その前後面の異なる位置に凹溝１５を設けたものであり、支持体２０を図例のように取付桟体１３を挟むように、前面の凹溝１５と後面の凹溝１５とよりなる係止部に架設したものである。 Further, the mounting bar 13 shown in FIG. 10 (b) is provided with concave grooves 15 at different positions on the front and rear surfaces thereof, and the support 20 is sandwiched between the mounting bars 13 as shown in the figure. These are constructed on a latching portion composed of a groove 15 on the front surface and a groove 15 on the rear surface.
　さらに、図１０（ｃ）に示した取付桟体１３は、その上面に係止凸部１４を設けたものであり、一対の吊下クリップ２２、２２の脚部２２ａ、２２ａを中途で折り曲げてなる支持体２０が係止凸部１４に引っ掛けられて弾性係止されるようになっている。 Furthermore, the mounting bar 13 shown in FIG. 10 (c) is provided with a locking projection 14 on its upper surface, and the legs 22a, 22a of the pair of hanging clips 22, 22 are bent halfway. The support 20 is hooked on the locking projection 14 and is elastically locked.
　なお、以上の種々の実施形態では、支持体２０は取付桟体１３に取り付けられるようにしたものを例示したが、ハンガー枠１１（図１参照）に係止部を設けて支持体２０を取り付けられるようにしてもよい。たとえば、ハンガー枠１１の前後面、側面に支持体２０を着脱自在に取り付けできるようにしてもよい。 In the above-described various embodiments, the support 20 is illustrated as being attached to the mounting bar 13, but the support 20 is attached by providing a locking portion on the hanger frame 11 (see FIG. 1). You may be made to do. For example, you may enable it to attach the support body 20 to the front-and-back surface and the side surface of the hanger frame 11 so that attachment or detachment is possible.
