本発明は電子機器の金属パネル等のエッジで電線の被覆が傷つかないように保護するためのエッジサポートに関するものである。
The present invention relates to an edge support for protecting an electric wire from being damaged by an edge of a metal panel or the like of an electronic device.
電子機器を組み立てるときに金属パネルのエッジに沿って被覆電線を延設する際に、電線の被覆が金属パネルのエッジと干渉し、エッジで被覆が傷ついてしまうことがある。特に近年では環境対策から鉛化合物を含まない、そしてダイオキシン類発生の原因であるハロゲン系元素を含まないノンハロゲン被覆の電線が提供されており、この種の被覆は従来の塩化ビニールのような被覆に比較して柔らかいため、電線の引回し時に被覆が金属パネルエッジと干渉したときに容易に被覆が傷つき、絶縁性が低下してしまう。
When the covered electric wire is extended along the edge of the metal panel when assembling the electronic device, the coating of the electric wire may interfere with the edge of the metal panel, and the coating may be damaged at the edge. In recent years, non-halogen-coated electric wires that do not contain lead compounds and do not contain halogen-based elements that cause dioxins have been provided as environmental measures, and this type of coating has been replaced with conventional vinyl chloride coatings. Since it is soft in comparison, the coating is easily damaged when the coating interferes with the metal panel edge when the electric wire is routed, resulting in a decrease in insulation.
この問題を解消するために従来からエッジサポートが提案されている。例えば、図１２に示すエッジサポート１Ｃは、細長い帯状片１１１の両側に沿って複数の舌片状をした挟持片１１２を長さ方向に所要のピッチで配設し、断面をコ字状にしたものである。このエッジサポート１Ｃは両側の挟持片１１２を金属パネル２のエッジに被せて板厚方向に挟持させることで金属パネル２のエッジを覆い、エッジが露呈することを防止し、被覆電線が金属パネルのエッジに直接接触して被覆が傷つくことを防止している。しかしながらこのエッジサポートは、単に挟持片で金属パネルを板厚方向に挟んでいるだけであるので、外力が加えられたときに挟持片が金属パネル面で滑り、容易に脱落してしまうという問題がある。特に、金属パネルの厚さが薄いときには挟持片による挟持力が小さく、より脱落し易くなる。また、金属パネルのエッジが長いときには複数個のエッジサポートを並べて装着するが、エッジサポートが滑りによって移動して隣り合うエッジサポート間に隙間が生じたときにこの隙間部分でエッジが露呈してしまい、被覆を保護することができなくなる。なお、エッジサポートを接着することも考えられるが、家電リサイクル法等に基づくリサイクルの際に電子機器の解体、部品取り外しが困難になるという問題がある。
In order to solve this problem, edge support has been proposed conventionally. For example, in the edge support 1C shown in FIG. 12, a plurality of tongue-shaped sandwiching pieces 112 are arranged along the both sides of the elongated strip-like piece 111 at a required pitch in the length direction, and the cross section is made U-shaped. Is. The edge support 1C covers the edges of the metal panel 2 by covering the edges of the metal panel 2 with the sandwiching pieces 112 on both sides in the thickness direction, thereby preventing the edges from being exposed. The coating is prevented from being damaged by direct contact with the edge. However, since this edge support simply sandwiches the metal panel with the sandwiching piece in the plate thickness direction, when an external force is applied, the sandwiching piece slides on the metal panel surface and easily falls off. is there. In particular, when the thickness of the metal panel is thin, the clamping force by the clamping piece is small, and the metal panel is more easily detached. Also, when the edge of the metal panel is long, a plurality of edge supports are mounted side by side. However, when the edge support moves due to sliding and a gap is formed between adjacent edge supports, the edge is exposed at this gap portion. The coating cannot be protected. Note that although it is conceivable to bond the edge support, there is a problem that it is difficult to disassemble the electronic device and remove the parts at the time of recycling based on the Home Appliance Recycling Law.
これに対し特許文献１には、脱落を防止する一方で取り外しを容易にしたエッジサポートが提案されている。特許文献１ではエッジサポートの一部ないし複数箇所の両側にヒンジにより連結された対をなすロック片を設け、これらロック片の一方にボス部を設け、他方にボス部に嵌合する孔部を設けている。金属エッジに沿って穴を開けておき、エッジサポートを金属パネルに装着するときに一方のロック片のボス部を当該穴に挿通し、他方のロック片を挿通したボス部に嵌合することで、両ロック片によって金属パネルを強固に挟持してエッシサポートの脱落を防止するとともに移動を防止することが可能になる。
特開２００２−１６８２０８号公報
On the other hand, Patent Document 1 proposes an edge support that can be easily removed while being prevented from falling off. In Patent Document 1, a pair of lock pieces connected by hinges are provided on both sides of a part or a plurality of positions of the edge support, a boss portion is provided on one of these lock pieces, and a hole portion that fits on the boss portion is provided on the other side. Provided. A hole is made along the metal edge, and when the edge support is attached to the metal panel, the boss part of one lock piece is inserted into the hole, and the boss part through which the other lock piece is inserted is fitted. It is possible to firmly hold the metal panel by both lock pieces to prevent the essence support from falling off and to prevent movement.

特許文献１のエッジサポートは、装着時には対をなすロック片の一方を曲げた後にボス部を穴に挿通させ、その後他方のロック片を曲げてボスに嵌合させる作業が必要になる。また、エッジサポートを取り外す際には、両方のロック片を広げる方向に曲げてボス部との嵌合を外す必要がある。そのため、エッジサポートの着脱の作業性が悪いという問題がある。特に、電子機器内の狭いスペースに配設された金属パネルに対してエッジサポートを着脱する作業が面倒なものになる。また、金属パネルの板厚に対してボス部の長さが短いとエッジサポートを装着することができず、逆にボス部を長くするとロック片と金属パネルの表面との間に隙間ができてしまい、板厚方向に取り付けガタが生じてしまうという問題もある。さらに、隣り合うエッジサポートを密接して両者間に隙間が生じることを防止するためには、金属パネルに開ける穴の寸法精度や位置精度を高精度に管理する必要があり、加工が難しいものになるという問題もある。
The edge support of Patent Document 1 requires an operation of bending one of the paired lock pieces, inserting the boss portion through the hole, and then bending the other lock piece to fit the boss at the time of mounting. Moreover, when removing an edge support, it is necessary to bend in the direction which expands both lock pieces, and to disengage from a boss | hub part. Therefore, there is a problem that the workability of attaching / detaching the edge support is poor. In particular, the work of attaching / detaching the edge support to / from the metal panel arranged in a narrow space in the electronic device becomes troublesome. Also, if the length of the boss is shorter than the thickness of the metal panel, the edge support cannot be attached. Conversely, if the length of the boss is increased, a gap is created between the lock piece and the surface of the metal panel. Therefore, there is also a problem that mounting play occurs in the thickness direction. Furthermore, in order to prevent adjacent gaps between adjacent edge supports from forming closely, it is necessary to manage the dimensional accuracy and position accuracy of the holes drilled in the metal panel with high accuracy, making it difficult to machine. There is also a problem of becoming.
本発明の目的は、パネルのエッジに対する着脱作業を簡易化するとともに、パネルに対して確実にかつ安定した状態に装着することが可能なエッジサポートを提供するものである。
An object of the present invention is to provide an edge support that can be attached to a panel in a reliable and stable state while simplifying the attaching / detaching operation to the edge of the panel.
本発明は、パネルのエッジに沿うように細長く形成された帯状部と、この帯状部の両側に沿って長さ方向に所要の間隔で配設され、一方向に突出された複数の挟持片とを備えるエッジサポートであって、挟持片のうち帯状部の幅方向に対向する対をなす挟持片の内面にはそれぞれ内方に向けて突出され、パネルに開口した取付穴に当該パネルの両面からそれぞれ嵌合される係止爪を備える。また、帯状部の両端には当該帯状部の厚さの１／２以下の厚さで、板厚方向に弾性を有する所要長さの連結片を備える。好ましくは、対向する挟持片の各係止爪は長さ方向に隣り合って形成され、これらの各係止爪はパネルに開口した円形の取付穴に同時に嵌合されるとともに、両者を合わせた輪郭が取付穴の形状に対応する円形となるようなそれぞれ半円形に形成される。
The present invention provides a strip-shaped portion that is elongated along the edge of the panel, and a plurality of sandwiching pieces that are disposed along the both sides of the strip-shaped portion at a predetermined interval in the length direction and project in one direction. An edge support comprising: a pair of sandwiching pieces that protrude inward on the inner surfaces of the pair of sandwiching pieces facing in the width direction of the band-shaped portion, and are attached to both sides of the panel through mounting holes opened in the panel Each has a locking claw to be fitted . Moreover, the connection piece of the required length which has the thickness below the thickness of the said strip | belt-shaped part and has elasticity in a plate | board thickness direction is provided in the both ends of a strip | belt-shaped part. Preferably, each engagement claw of the opposing clamping pieces are formed adjacent in the longitudinal direction, the sum each of these engaging claws are fitted simultaneously in a circular mounting hole opened in the panel Rutotomoni, both each contour such that circular corresponding to the shape of the mounting hole Ru are semicircular.
本発明のエッジサポートによれば、パネルのエッジを挟持片間に挿入させるだけで挟持片に設けた係止片がパネルの両側から取付穴に嵌合してエッジサポートをパネルに保持させるので、エッジサポートが容易に脱落することはない。そのため、特許文献１のようにロック片を曲げ操作する作業は不要であり装着を容易に行うことができる。また、帯状部の両端には帯状部の厚さの１／２以下の厚さで、板厚方向に弾性を有する所要長さの連結片を備えるので、複数のエッジサポートを配列状態に装着したときにエッジサポートの連結片によって隣接するエッジサポート間にパネルのエッジが露呈することがなく、その一方で隣接するエッジサポートの連結片が互いに重なってもこの部分が外側に膨らむことがなく外観上の見栄えが低下することもない。さらに、対向する挟持片の係止爪を長さ方向に隣り合って形成することで、係止爪の突出長さを長くでき、取付穴との引っ掛かり寸法を大きくして脱落をより確実に防止することができる。さらに、隣り合う係止爪の輪郭を取付穴の形状とすることで、円形の取付穴に各係止爪を嵌合させることができ、取付穴の加工も容易になる。
According to the edge support of the present invention, since the edge of the panel is inserted between the sandwiching pieces, the locking pieces provided on the sandwiching piece are fitted into the mounting holes from both sides of the panel and the edge support is held on the panel. Edge support does not fall off easily. Therefore, the operation | work which bends a lock piece like patent document 1 is unnecessary, and it can mount | wear easily. In addition, since both ends of the belt-like portion are provided with connecting pieces having a required length having a thickness of 1/2 or less of the thickness of the belt-like portion and having elasticity in the plate thickness direction, a plurality of edge supports are mounted in an arrayed state. Sometimes the edge of the panel does not expose the edge of the panel between the adjacent edge supports, while the adjacent edge support does not bulge outward even if the adjacent edge support overlaps each other. The appearance of will not decline. Furthermore, by forming the engaging claws of the opposing clamping pieces adjacent to each other in the length direction, the protruding length of the engaging claws can be increased, and the catching dimension with the mounting hole is increased to prevent the dropping more reliably. can do. Furthermore, by setting the contour of the adjacent locking claws to the shape of the mounting hole, each locking claw can be fitted into the circular mounting hole, and the processing of the mounting hole is facilitated.
次に、本発明の実施例１を図面を参照して説明する。図１（ａ）は本発明のエッジサポートの外観斜視図、図２（ａ）〜（ｃ）は平面図、正面図及び左側面図である。これらの図に示すように、エッジサポート１は若干の弾性を有する樹脂で成形されており、細長い帯状部１１と、この帯状部１１の内面から図の下方に向けて所要の寸法で突出し、帯状部１１の両側に沿って長さ方向に所要のピッチ寸法で配設されてそれぞれ帯状部１１の幅方向に対向して対をなす複数の小挟持片１２と、前記帯状部１１の両端部において前記小挟持片１２よりも長い寸法で突出されて帯状部１１の幅方向に対向して対をなす大挟持片１３とを備えている。これら小挟持片１２と大挟持片１３は先端が円弧状をし、それぞれの内面が対向する間隔は等しく、所定の間隔寸法に設定されている。
Next, Embodiment 1 of the present invention will be described with reference to the drawings. FIG. 1A is an external perspective view of the edge support of the present invention, and FIGS. 2A to 2C are a plan view, a front view, and a left side view. As shown in these drawings, the edge support 1 is formed of a resin having a slight elasticity, and is elongated with a required dimension from the inner surface of the strip-shaped portion 11 and the inner surface of the strip-shaped portion 11 toward the lower side of the figure. A plurality of small sandwiching pieces 12 that are arranged along the both sides of the portion 11 in the lengthwise direction with a required pitch dimension and that are opposed to each other in the width direction of the belt-like portion 11, and at both ends of the belt-like portion 11 A large holding piece 13 that protrudes in a longer dimension than the small holding piece 12 and faces the width direction of the belt-like portion 11 and forms a pair is provided. The small sandwiching piece 12 and the large sandwiching piece 13 have arcuate tips, and the distances between the inner faces thereof are equal and set to a predetermined spacing dimension.
前記帯状部１１の上面は前記小挟持片１２及び大挟持片１３が配設された領域において長さ方向の断面形状が円弧状に幾分突出して板厚が大きくされており、小挟持片１２及び大挟持片１３の機械的な強度を高めて後述するように金属パネル２に対する挟持力を増大させた補強部１４として形成されている。前記帯状部１１の長さ方向の両端部には、それぞれ長さ方向外側に向けて薄肉で円弧状をした連結片１５が突出されている。この連結片１５の板厚は前記帯状部１１の最大寸法の厚さ、この例では前記補強部１４の厚さの１／２以下の厚さに形成されている。また、外側への突出長さは前記ピッチ寸法程度、ないしは若干長めに形成されており、その先端は帯状部１１の内面と同じ面上の位置か、この面よりも図の下方に位置されている。さらに、図２（ｂ）に示すように、小挟持片１２の間及び小挟持片１２と大挟持片１３の間、さらに大挟持片１３と連結片１５との間の帯状部１１の内面に小円弧状断面の凹溝１６が設けられ、この凹溝１６により帯状部１１の板厚を部分的に小さくして帯状部１１を長さ方向に曲げ変形し易くしている。
The upper surface of the band-shaped portion 11 has a cross-sectional shape that protrudes somewhat in an arc shape in a region where the small sandwiching piece 12 and the large sandwiching piece 13 are arranged, and the plate thickness is increased. Further, as described later, the reinforcing portion 14 is formed by increasing the mechanical strength of the large clamping piece 13 and increasing the clamping force with respect to the metal panel 2. At both ends in the length direction of the belt-like portion 11, connecting pieces 15 having a thin arc shape projecting outward in the length direction. The plate thickness of the connecting piece 15 is formed to be the thickness of the maximum dimension of the strip-like portion 11, in this example, ½ or less of the thickness of the reinforcing portion 14. Further, the outward projecting length is about the pitch dimension or slightly longer, and the tip thereof is located on the same surface as the inner surface of the strip 11 or below the surface in the figure. Yes. Further, as shown in FIG. 2B, on the inner surface of the belt-like portion 11 between the small sandwiching pieces 12, between the small sandwiching pieces 12 and the large sandwiching piece 13, and between the large sandwiching piece 13 and the connecting piece 15. A concave groove 16 having a small arc-shaped cross section is provided, and the thickness of the strip portion 11 is partially reduced by the concave groove 16 so that the strip portion 11 is easily bent and deformed in the length direction.
前記対をなす大挟持片１３は対向しているそれぞれの内面に内方に向けて係止爪１３１が突出形成されている。図３は一対の大挟持片１３の拡大斜視図であり、これらの係止爪１３１はここでは正面から見て円形をしており、図２（ｃ）に示すように、各係止爪１３１は樹脂成形での製造を可能とするために両係止爪１３１の突出先端面の間には微小な間隙ｄが確保されている。各係止爪１３１は上縁部１３１ａは大挟持片１３の内面に対して垂直に向けられているが、下縁部１３１ｂはテーパ状に傾斜されている。なお、この係止爪１３１を成形するための金型の離型を可能とするために大挟持片１３の補強部１４には板厚方向に向けて平面形状が長方形の窓１７が開口されている。
The pair of large holding pieces 13 are formed with locking claws 131 projecting inwardly on the inner surfaces facing each other. FIG. 3 is an enlarged perspective view of the pair of large holding pieces 13, and these locking claws 131 are circular when viewed from the front here, and as shown in FIG. In order to enable manufacture by resin molding, a minute gap d is secured between the projecting tip surfaces of the two locking claws 131. Each locking claw 131 has an upper edge portion 131a oriented perpendicularly to the inner surface of the large clamping piece 13, while a lower edge portion 131b is inclined in a tapered shape. Note that a window 17 having a rectangular planar shape is opened in the reinforcing portion 14 of the large clamping piece 13 in the plate thickness direction so that the mold for forming the locking claw 131 can be released. Yes.
図１（ａ）に示したように、このエッジサポート１を金属パネル２に装着するために、金属パネル２には予めエッジに沿って取付穴２１を開口しておく。この取付穴２１はエッジサポート１の大挟持片１３の係止爪１３１に対応する円形の穴である。そして、図４（ａ）に示すように、エッジサポート１を装着するときには、小挟持片１２と大挟持片１３の対向間隔内に金属パネル２のエッジが進入するようにエッジサポート１を金属パネル２のエッジに被せるように嵌め込んで行く。所定量だけ嵌め込んで行くと係止爪１３１が取付穴２１に嵌入する。図４（ｂ）はそのときの図４（ａ）のＡ−Ａ線に相当する断面図である。このとき係止爪１３１の下縁部１３１ｂはテーパ状であるため大挟持片１３は両外側に若干弾性変形しながら係止爪１３１が金属パネル２のエッジを乗り越えて金属パネル２の表面を滑り、取付穴２１の位置で大挟持片１３が弾性復帰することにより各係止爪１３１が取付穴２１に嵌合する。
As shown in FIG. 1A, in order to attach the edge support 1 to the metal panel 2, a mounting hole 21 is opened in advance along the edge of the metal panel 2. The mounting hole 21 is a circular hole corresponding to the locking claw 131 of the large clamping piece 13 of the edge support 1. Then, as shown in FIG. 4A, when the edge support 1 is mounted, the edge support 1 is attached to the metal panel so that the edge of the metal panel 2 enters the space between the small holding piece 12 and the large holding piece 13 facing each other. Fit it over the edge of 2. When a predetermined amount is inserted, the locking claw 131 is inserted into the mounting hole 21. FIG. 4B is a cross-sectional view corresponding to the line AA in FIG. At this time, since the lower edge portion 131b of the locking claw 131 is tapered, the large clamping piece 13 is slightly elastically deformed to the outside while the locking claw 131 gets over the edge of the metal panel 2 and slides on the surface of the metal panel 2. When the large clamping piece 13 is elastically restored at the position of the mounting hole 21, each locking claw 131 is fitted into the mounting hole 21.
このように装着した状態を図１（ｂ）に示す。金属パネル２はエッジサポート１の長さ方向の複数箇所において複数の小挟持片１２によって挟持され、さらにエッジサポートの両端部において大挟持片１３によって挟持された状態となる。このとき、小挟持片１２は自身の弾性力によって内面が金属パネル２の表面に当接し、この当接力によって生じる摩擦力により挟持した状態が保持される。小挟持片１２が設けられた帯状部１１には補強部１４が設けられているので、小挟持片１２の弾性力が高められ、エッジサポートの強度が保持される。一方、大挟持片１３の各係止爪１３１が金属パネル２の両面からそれぞれ取付穴２１に嵌合することによっても挟持した状態が保持される。取付穴２１と係止爪１３１との嵌合によりエッジサポート１が金属パネル２の表面に沿って移動することはなく、確実に位置決めすることができる。また、取付穴２１に嵌入された係止爪１３１は上縁部１３１ａが垂直であり、取付穴２１の上側の内縁に垂直方向に当接するため、単にエッジサポート１を外側に引っ張るのみでは係止爪１３１が取付穴２１から外れることはなく、エッジサポート１がエッジから容易に脱落されることはない。
FIG. 1 (b) shows the state of mounting in this way. The metal panel 2 is sandwiched by a plurality of small sandwiching pieces 12 at a plurality of locations in the length direction of the edge support 1 and further sandwiched by large sandwiching pieces 13 at both ends of the edge support. At this time, the inner surface of the small clamping piece 12 is brought into contact with the surface of the metal panel 2 by its own elastic force, and the state of being held by the frictional force generated by this contact force is maintained. Since the belt-like portion 11 provided with the small sandwiching piece 12 is provided with the reinforcing portion 14, the elastic force of the small sandwiching piece 12 is increased and the strength of the edge support is maintained. On the other hand, the holding state is also maintained by fitting the locking claws 131 of the large holding piece 13 into the mounting holes 21 from both sides of the metal panel 2. The edge support 1 does not move along the surface of the metal panel 2 by the fitting of the mounting hole 21 and the locking claw 131, and can be positioned reliably. Further, the locking claw 131 fitted in the mounting hole 21 has a vertical upper edge 131a and abuts the inner edge on the upper side of the mounting hole 21 in the vertical direction. The claw 131 does not come off from the mounting hole 21, and the edge support 1 is not easily detached from the edge.
このように、実施例１のエッジサポート１は、それぞれ対をなす小挟持片１２と大挟持片１３との間に金属パネル２のエッジを挿入すれば、大挟持片１３の係止爪１３１が取付穴２１に嵌合し、エッジサポート１の両端部をエッジに対して挟持させるとともに中間部を複数の小挟持片１２によって挟持する状態となり、エッジサポート１が容易に脱落することはない。したがって、エッジサポート１を装着する際に特許文献１のようにロック片を曲げ操作する作業は不要であり装着を容易に行うことができる。さらに、エッジサポート１をエッジに装着したときに連結片１５がエッジ端面に当接してその反力でエッジサポート１をエッジ外方に付勢するので、係止爪１３１の上端部１３１ａと取付穴２１の内縁との間に当接力を発生させ、係止爪１３１と取付穴２１との間の摩擦力を増大することで脱落をより有効に防止することができる。
As described above, in the edge support 1 of the first embodiment, when the edge of the metal panel 2 is inserted between the pair of the small sandwiching piece 12 and the large sandwiching piece 13, the locking claws 131 of the large sandwiching piece 13 are formed. The both ends of the edge support 1 are fitted to the mounting hole 21 and the intermediate portion is held by the plurality of small holding pieces 12 so that the edge support 1 is not easily dropped off. Therefore, when the edge support 1 is mounted, the operation of bending the lock piece as in Patent Document 1 is unnecessary, and the mounting can be easily performed. Further, when the edge support 1 is attached to the edge, the connecting piece 15 abuts on the edge end face and the reaction force urges the edge support 1 outward from the edge. Dropping off can be prevented more effectively by generating a contact force with the inner edge of 21 and increasing the frictional force between the locking claw 131 and the mounting hole 21.
また、図５に示すように、複数のエッジサポート１を長さ方向に並べて金属パネル２のエッジに装着する際には、隣のエッジサポート１の連結片１５が互いに重なるように配列寸法を設定することで、各連結片１５によって隣り合うエッジサポート１の間にエッジが露呈するような隙間が生じることはなく、図１２に示した従来のエッジサポート１Ｃのように隣り合うエッジサポート間の隙間で被覆が傷つくこともない。このとき、各連結片１５は薄肉であるため弾性による変形性が高く、互いに重なったときには密接状態となり、しかもこの状態では補強部１４よりも上方に突出することはない。特に、隣り合うエッジサポートの各連結片１５が重なった場合に、どちらのエッジサポートが上になっても重なった連結片１５が補強部１４よりも上方に突出することはない。そのため、連結片１５の部分でエッジサポートが外側に膨らむことがなく、外観上の見栄えが低下することがなく、また被覆電線が引っ掛かかってしまうようなこともない。また、各エッジサポート１には方向性が存在しないため、装着に際して取付方向を考慮する必要もなく、この点でも装着作業が容易になる。
In addition, as shown in FIG. 5, when a plurality of edge supports 1 are arranged in the length direction and attached to the edge of the metal panel 2, the arrangement dimensions are set so that the connecting pieces 15 of the adjacent edge supports 1 overlap each other. By doing so, there is no gap between the edge supports 1 adjacent to each other by the connecting pieces 15, and the gap between the adjacent edge supports like the conventional edge support 1C shown in FIG. The coating will not be damaged. At this time, since each connecting piece 15 is thin, it is highly deformable by elasticity. When the connecting pieces 15 overlap each other, the connecting pieces 15 are in close contact with each other, and in this state, do not protrude upward from the reinforcing portion 14. In particular, when the connecting pieces 15 of adjacent edge supports overlap, the overlapping connecting pieces 15 do not protrude upward from the reinforcing portion 14 regardless of which edge support is on top. Therefore, the edge support does not bulge outward at the connecting piece 15, the appearance is not deteriorated, and the covered electric wire is not caught. Further, since there is no directionality in each edge support 1, it is not necessary to consider the mounting direction when mounting, and the mounting operation is facilitated in this respect as well.
図６（ａ）〜（ｃ）は本発明の実施例２の正面図である。外観の構成は図１に示した実施例１とほぼ同じであるので、実施例１と等価な部分には同一符号を付してある。実施例２のエッジサポート１Ａは、実施例１と同様に、若干の弾性を有する樹脂で成形された細長い帯状部１１と、この帯状部１１の内面から図の下方に向けて所要の寸法で突出し、帯状部１１の両側に沿って長さ方向に所要のピッチ寸法で配設され、それぞれ帯状部１１の幅方向に対をなす複数の小挟持片１２と、前記帯状部１１の両端部において前記小挟持片１２よりも長い寸法で突出されて帯状部１１の幅方向に対をなす大挟持片１３とを備えている。また、これら小挟持片１２と大挟持片１３は先端が円弧状をし、それぞれの内面が対向する間隔は等しく、所定の間隔寸法に設定されている。
6A to 6C are front views of Embodiment 2 of the present invention. Since the external configuration is substantially the same as that of the first embodiment shown in FIG. 1, the same reference numerals are given to the parts equivalent to the first embodiment. As in the first embodiment, the edge support 1A according to the second embodiment protrudes from the inner surface of the belt-shaped portion 11 to the lower side of the figure with a required dimension. A plurality of small sandwiching pieces 12 that are arranged along the both sides of the belt-like portion 11 with a required pitch dimension in the lengthwise direction and that make a pair in the width direction of the belt-like portion 11, and at both ends of the belt-like portion 11, A large holding piece 13 that protrudes in a longer dimension than the small holding piece 12 and forms a pair in the width direction of the belt-like portion 11 is provided. Further, the small sandwiching piece 12 and the large sandwiching piece 13 have arcuate ends, and the distances between the inner surfaces of the small sandwiching piece 12 and the large sandwiching piece 13 are equal and set to a predetermined spacing dimension.
さらに、帯状部１１の上面には前記小挟持片１２及び大挟持片１３が形成された領域において長さ方向の断面形状が円弧状に幾分突出して板厚を大きくし、小挟持片１２及び大挟持片１３の機械的な強度を高めて挟持力を増大させた補強部１４が設けられている。また、前記両側の各大挟持片１３の外側には、帯状部１１の両端を外側に向けて突出した薄肉で円弧状をした連結片１５が突出されている。この連結片１５の板厚及び突出長さは実施例１と同じである。小挟持片１２、大挟持片１３、連結片１５の各間には帯状部１１の内面に小円弧状断面の凹溝１６が設けられ、帯状部１１が長さ方向に曲げ変形され易くなっていることも実施例１と同じである。
Further, in the region where the small sandwiching piece 12 and the large sandwiching piece 13 are formed on the upper surface of the belt-like portion 11, the cross-sectional shape in the length direction protrudes somewhat in an arc shape to increase the plate thickness, and the small sandwiching piece 12 and A reinforcing portion 14 is provided in which the mechanical strength of the large clamping piece 13 is increased to increase the clamping force. Further, on the outside of each large clamping piece 13 on both sides, a connecting piece 15 having a thin circular arc shape protruding from both ends of the belt-like portion 11 outward is projected. The plate thickness and protruding length of the connecting piece 15 are the same as those in the first embodiment. Between each of the small clamping piece 12, the large clamping piece 13, and the connecting piece 15, a concave groove 16 having a small arc-shaped cross section is provided on the inner surface of the strip-shaped portion 11, and the strip-shaped portion 11 is easily bent and deformed in the length direction. This is the same as in the first embodiment.
一方、図７に前記対をなす大挟持片１３の拡大斜視図を示すように、対向している各大挟持片１３の対向面に係止爪１３２が突出形成されていることは実施例１と同じであるが、実施例２では両方の係止爪１３２は半円形をして帯状部１１の長さ方向に沿って隣り合う位置に配設されている。両係止爪の直径部分を向かい合わせて両方の係止爪で円形の輪郭を構成した構成となっている。すなわち、各係止爪１３２は樹脂成形での金型の抜きが可能な限度で、各係止爪１３２の突出先端面は帯状部１１の幅方向の中間位置、あるいはそれぞれが中間位置を若干だけ越える位置となるように突出寸法が可及的に大きくなるように設計されている。また、各係止爪１３２は上縁部１３２ａが大挟持片１３の内面に対して垂直に向けられているが、下縁部１３２ｂはテーパ状に傾斜されている。この係止爪１３２を成形する際に金型の抜きを可能とするために大挟持片１３の補強部１４には板厚方向に窓１７が開口されている。
On the other hand, as shown in the enlarged perspective view of the pair of large holding pieces 13 in FIG. 7, the engaging claws 132 are formed so as to protrude on the opposing surfaces of the large holding pieces 13 facing each other. However, in the second embodiment, both the locking claws 132 are semicircular and arranged at positions adjacent to each other along the length direction of the belt-like portion 11. A circular contour is formed by both the locking claws with the diameter portions of both the locking claws facing each other. In other words, each locking claw 132 is limited to the extent that the mold can be removed by resin molding, and the protruding front end surface of each locking claw 132 is an intermediate position in the width direction of the belt-shaped portion 11 or each has a slightly intermediate position The protruding dimension is designed to be as large as possible so as to be in a position beyond the above. In addition, each of the locking claws 132 has an upper edge portion 132a oriented perpendicularly to the inner surface of the large clamping piece 13, while the lower edge portion 132b is inclined in a tapered shape. A window 17 is opened in the thickness direction in the reinforcing portion 14 of the large clamping piece 13 so that the mold can be removed when the locking claw 132 is formed.
このエッジサポート１Ａは実施例１と同様に金属パネルに装着することが可能である。すなわち、図４（ａ）を再度参照すると、金属パネル２には実施例１で説明したと同様に予めエッジに沿って取付穴２１を開口しておく。この取付穴２１はエッジサポート１Ａの対向する大挟持片１３の各係止爪１３２を正面方向から見たときに両者を包含する輪郭に対応した円形の穴である。そして、エッジサポート１Ａの小挟持片１２と大挟持片１３の対向間隔内に金属パネル２のエッジが進入するようにエッジサポート１Ａを金属パネル２に嵌め込むことにより、係止爪１３２が取付穴２１に嵌入する。このとき両側の係止爪１３２はそれぞれ同じ一つの取付穴２１に嵌入する。係止爪１３２の下端部１３２ｂはテーパ状であるため大挟持片１３は両外側に若干弾性変形しながら係止爪１３２が金属パネル２のエッジを乗り越えて金属パネル２の表面を滑り、取付穴２１の位置で大挟持片１３の弾性復帰により各係止爪１３２が取付穴２１に嵌合する。
The edge support 1A can be attached to a metal panel as in the first embodiment. That is, referring to FIG. 4A again, the metal panel 2 is previously provided with the attachment holes 21 along the edges in the same manner as described in the first embodiment. This attachment hole 21 is a circular hole corresponding to a contour including both when the respective locking claws 132 of the large holding piece 13 facing the edge support 1A are viewed from the front. Then, when the edge support 1A is fitted into the metal panel 2 so that the edge of the metal panel 2 enters the space between the small holding piece 12 and the large holding piece 13 of the edge support 1A, the locking claw 132 is attached to the mounting hole. 21. At this time, the locking claws 132 on both sides are fitted into the same mounting hole 21 respectively. Since the lower end portion 132b of the locking claw 132 is tapered, the large clamping piece 13 is slightly elastically deformed outwards while the locking claw 132 rides over the edge of the metal panel 2 and slides on the surface of the metal panel 2, thereby mounting holes. Each locking claw 132 is fitted into the mounting hole 21 by the elastic return of the large clamping piece 13 at the position 21.
このように、実施例２のエッジサポート１Ａも実施例１と同様に大挟持片１３の係止爪１３２が取付穴２１に嵌合し、かつ複数の小挟持片１２が金属パネル２のエッジを挟持する状態となる。このとき、１つの取付穴２１に２つの係止爪１３２が金属パネル２の両面からそれぞれ同時に嵌合され、これら係止爪１３２と取付穴２１との嵌合によってエッジサポートの位置決めが可能になる。しかもこれらの係止爪１３２は上縁部１３２ａが垂直であり、取付穴２１の上側の内縁に垂直方向に当接するため、係止爪１３２が取付穴２１から容易に外れることがなく、エッジサポートがエッジから脱落することがないことも同じである。また、実施例２では実施例１のように係止爪１３２の対向間に図２（ｃ）に示したような間隙ｄが必要とされないので、各係止爪１３２の突出長さを実施例１よりも大きく形成でき、図８（ａ）のように、板厚の厚い金属パネル２の場合には係止爪１３２と取付穴２１との引っ掛かり寸法（両者が板厚方向に重なる寸法）を全板厚にわたって確保でき、エッジサポート１Ａの挟持の安定性が高められる。また、図８（ｂ）に示すように、エッジサポート１Ａを板厚の薄い金属パネル２Ａに装着した場合でも各係止爪１３２と取付穴２１との引っ掛かり寸法を金属パネル２Ａの全板厚にわたって確保でき、実施例１の構成よりも大きくでき、係止を確実なものにできる。
As described above, in the edge support 1A according to the second embodiment, the locking claws 132 of the large holding pieces 13 are fitted into the mounting holes 21 as in the first embodiment, and the plurality of small holding pieces 12 serve as the edges of the metal panel 2. It will be in the state of pinching. At this time, two locking claws 132 are simultaneously fitted into one mounting hole 21 from both surfaces of the metal panel 2, and the edge support can be positioned by fitting the locking claws 132 with the mounting holes 21. . Moreover, since the upper claw 132 has a vertical upper edge 132a and abuts the upper edge of the mounting hole 21 in the vertical direction, the locking claw 132 is not easily detached from the mounting hole 21, and the edge support is supported. It is the same that no fall off from the edge. Further, in the second embodiment, unlike the first embodiment, the gap d as shown in FIG. 2 (c) is not required between the opposing claws 132. In the case of a thick metal panel 2 as shown in FIG. 8 (a), the hook dimension between the locking claw 132 and the mounting hole 21 (the dimension in which both overlap in the thickness direction) is set. It can be secured over the entire plate thickness, and the stability of clamping the edge support 1A is enhanced. Further, as shown in FIG. 8 (b), even when the edge support 1A is mounted on the thin metal panel 2A, the catching dimension between the locking claws 132 and the mounting holes 21 is set over the entire thickness of the metal panel 2A. It can be ensured, can be made larger than the configuration of the first embodiment, and the locking can be ensured.
図９（ａ），（ｂ）は本発明のエッジサポート１Ｂの実施例３の平面図と正面図である。実施例１と等価な部分には同一符号を付してある。実施例３では帯状部１１の両側に形成した対をなす大挟持片１３を帯状部１１の長さ方向に沿って互いにずらした位置に形成している。そして、各大挟持片１３の内面に形成する係止爪１３３は、樹脂成形時の金型の抜きの制約が少ないことから、係止爪１３３の突出寸法は可及的に大きな寸法、すなわち実施例３では金属パネル２の板厚にほぼ等しい寸法に形成している。各係止爪１３３は正面から見て円形をしていることは実施例１と同じである。また、図示は省略するが、係止爪１３３の幅方向の断面形状は上縁部が大挟持片１３の内面に垂直で、下縁部がテーパ状をしていることも実施例１と同じである。なお、実施例３では小挟持片１２についても帯状部１１の長さ方向に異なる位置に配設しているが、これは実施例１，２と同様に互いに対向するように配設してもよい。
FIGS. 9A and 9B are a plan view and a front view of Embodiment 3 of the edge support 1B of the present invention. Parts equivalent to those in the first embodiment are denoted by the same reference numerals. In the third embodiment, a pair of large holding pieces 13 formed on both sides of the belt-like portion 11 are formed at positions shifted from each other along the length direction of the belt-like portion 11. And since the latching claw 133 formed in the inner surface of each large clamping piece 13 has few restrictions of the extraction of the metal mold | die at the time of resin molding, the protrusion dimension of the latching claw 133 is as large as possible, ie, implementation. In Example 3, the metal panel 2 is formed to have a size approximately equal to the plate thickness. Each locking claw 133 is circular as viewed from the front, similar to the first embodiment. Although not shown, the cross-sectional shape of the locking claw 133 in the width direction is the same as in the first embodiment in that the upper edge is perpendicular to the inner surface of the large clamping piece 13 and the lower edge is tapered. It is. In the third embodiment, the small sandwiching pieces 12 are also arranged at different positions in the length direction of the belt-like portion 11, but this may be arranged so as to face each other as in the first and second embodiments. Good.
このエッジサポート１Ｂを金属パネル２に装着する際には、金属パネル２には図１０（ａ）のように、対をなす大挟持片１３の各係止爪１３３が嵌合可能なように長穴形状の取付穴２２を開口する。この場合には実施例１，２と同様に２つの大挟持片１３に対して１つの取付穴２２を形成すればよく、この１つの取付穴２２に２つの係止爪１３３が金属パネル２の両側から嵌合される。あるいは、図１０（ｂ）のように、金属パネル２には各係止爪１３３に対応するように２つの円形の取付穴２３を開口すればよい。この場合には取付穴２３は実施例１，２と同様に単純な円形の穴でよい。
When the edge support 1B is attached to the metal panel 2, the metal panel 2 is long enough to fit the engaging claws 133 of the large holding piece 13 forming a pair as shown in FIG. A hole-shaped attachment hole 22 is opened. In this case, it is only necessary to form one mounting hole 22 for the two large clamping pieces 13 as in the first and second embodiments, and two locking claws 133 are formed in the one mounting hole 22 of the metal panel 2. Mated from both sides. Alternatively, as shown in FIG. 10B, the metal panel 2 may be provided with two circular mounting holes 23 so as to correspond to the respective locking claws 133. In this case, the mounting hole 23 may be a simple circular hole as in the first and second embodiments.
実施例３のエッジサポート１Ｂでも実施例１，２と同様に金属パネル２に対する装着や取り外しが容易であり、その一方でエッジに対して確実に装着するとともにその脱落が防止でき、電線の被覆が傷つくことを確実に防止することができる。また、実施例３では、各係止爪１３３の突出長さを実施例２よりもさらに大きくできるので、係止爪１３３と取付穴２２，２３との引っ掛かり寸法が大きくなり、係止爪１３３が取付穴２２，２３から外れ難くなってエッジサポート１Ｂが金属パネル２からより脱落し難くなる。
The edge support 1B of the third embodiment can be easily attached to and detached from the metal panel 2 as in the first and second embodiments. On the other hand, the edge support 1B can be securely attached to the edge and can be prevented from falling off. It can be surely prevented from being damaged. In the third embodiment, the protruding length of each locking claw 133 can be made larger than that in the second embodiment, so that the catching dimension between the locking claw 133 and the mounting holes 22 and 23 is increased, and the locking claw 133 is The edge support 1 </ b> B is less likely to be detached from the metal panel 2 because it is difficult to come off the mounting holes 22 and 23.
実施例１〜３のエッジサポートは帯状部１１の内面に設けた複数の凹溝１６によって板厚方向の変形が容易にされているので、図１１に実施例１のエッジサポート１の例を示すように金属パネル２のコーナエッジに対しても装着することが可能である。前述した小挟持片１２のピッチ寸法と突出長さを適切に設定しておくことで、エッジサポート１を中間部位で９０度曲げても隣り合う小挟持片１２が互いに干渉するようなことはない。このようにコーナエッジへの装着は実施例２，３のエッジサポートでも同じである。
Since the edge supports of the first to third embodiments are easily deformed in the thickness direction by the plurality of concave grooves 16 provided on the inner surface of the belt-like portion 11, an example of the edge support 1 of the first embodiment is shown in FIG. Thus, it is possible to attach to the corner edge of the metal panel 2 as well. By appropriately setting the pitch dimension and the protruding length of the small sandwiching piece 12 described above, the adjacent small sandwiching pieces 12 do not interfere with each other even if the edge support 1 is bent 90 degrees at the intermediate portion. . As described above, the mounting to the corner edge is the same for the edge supports of the second and third embodiments.
なお、前記実施例１〜３において、係止爪の形状は実施例１，３のような円形、あるいは実施例２のような半円形に限られるものではない。金属パネルに開口する取付穴を任意の形状の取付穴として形成することが可能であるならば、係止爪を矩形、多角形に形成してもよいことは言うまでもない。これらの場合には実施例２の係止爪は各形状を１／２に分割した構成とすることは勿論である。
In the first to third embodiments, the shape of the locking claw is not limited to the circular shape as in the first and third embodiments or the semicircular shape as in the second embodiment. Needless to say, the locking claws may be formed in a rectangular shape or a polygonal shape as long as the mounting holes opened in the metal panel can be formed as mounting holes of an arbitrary shape. In these cases, it is a matter of course that the locking claw of the second embodiment has a configuration in which each shape is divided in half.
なお、エッジサポート１を金属パネル２から取り外すときには、例えば図１（ｂ）に示すように、エッジサポート１の窓１７内に金属パネル２の板厚と同じ間隔の二股治具Ｊを挿入することにより、対をなす大挟持片１３を両外側に弾性変形させ、係止爪１３１を取付穴２１との嵌合から解除できる。このとき、大挟持片１３は治具Ｊの両外面に対して弾接した状態になるため、治具Ｊをそのまま上方に持ち上げるだけでエッジサポート１を金属パネル２から離脱させることができる。そのため、環境問題等で要求されるリユースに対処することが容易である。
When removing the edge support 1 from the metal panel 2, for example, as shown in FIG. 1B, a bifurcating jig J having the same interval as the plate thickness of the metal panel 2 is inserted into the window 17 of the edge support 1. Thus, the pair of large holding pieces 13 can be elastically deformed to both outer sides, and the locking claw 131 can be released from the fitting with the mounting hole 21. At this time, since the large clamping piece 13 is in elastic contact with both outer surfaces of the jig J, the edge support 1 can be detached from the metal panel 2 simply by lifting the jig J upward. Therefore, it is easy to cope with the reuse required for environmental problems.
