- the third notch 33 functions as a release recess into which a tool or finger can be inserted when removing the first engaging portion 40 of the first connecting member 12 from the engaged portion 30 of the first link plate 21.
- the first connecting member 12 has a plate-shaped main body portion 12a, a first engaging portion 40 that engages with the first engaged portion 30a of the first link plate 21, and a second engaging portion 50 that engages with the second engaged portion 30b of the second link plate 22.
- the main body 12a has a plate surface aligned in the serial direction X and extends elongatedly in the width direction Y.
- the first engagement portion 40 has a curved portion 41 extending from one longitudinal end of the main body portion 12a, a hanging wall 42 extending downward from the outer end of the curved portion 41 along the thickness direction of the main body portion 12a, and an outward protruding wall 44 protruding outward from the upper end of the hanging wall 42.
- crank-like means a shape with two or more points that are curved in opposite directions.
- the hanging wall 42 "extending downward along the thickness direction of the main body 12a" does not necessarily have to coincide completely with the thickness direction of the main body 12a, but also includes a direction that is slightly inclined relative to the thickness direction of the main body 12a.
- the first engagement portion 40 has an inward protrusion 43 that protrudes inwardly at the lower end of the hanging wall 42 and serves as an inner engagement portion.
- the inward protrusion 43 has an inclined surface 43a that is inclined diagonally upward inward.
- the inward protrusion 43 also has a parallel surface 43b above the inclined surface 43a that extends parallel to the longitudinal direction of the main body 12a.
- the protruding length of the outwardly protruding wall 44 is such that the tip of the outwardly protruding wall 44 does not protrude from the outer end of the first link plate 21 when the first engaging portion 40 is attached to the first engaged portion 30a of the first link plate 21. Specifically, the tip of the outwardly protruding wall 44 is flush with the outer end of the first link plate 21.
- the upper surface which is the outer surface of the outwardly protruding wall 44 is located lower than the upper surface which is the outer surface of the main body portion 12 a of the first connecting member 12 .
- the length of the first engagement portion 40 along the serial direction X i.e., the widths of the curved portion 41, the hanging wall 42, the inward convex portion 43, and the outward protruding wall 44 along the serial direction X, are slightly smaller than the width of the second notch 32 along the same direction.
- the second engagement portion 50 has a protruding piece 51 protruding outward from the other end of the main body portion 12a in the longitudinal direction, and a hinge shaft 52 protruding on both sides in the lateral direction of the main body portion 12a from the tip of the protruding piece 51.
- the cross section of the hinge shaft 52 is circular.
- the second connecting member 13 is made of a long plate material.
- the second connecting member 13 connects the lower ends of the pair of link plates 11.
- the second connecting member 13 is attached at a position overlapping the first connecting member 12 in the up-down direction Z.
- the hinge shaft 52 is restricted from moving further inwardly of the second link plate 22 while in contact with the semicircular periphery of the hinge bearing portion 31a. This causes the second engaging portion 50 of the first connecting member 12 to engage with the second engaged portion 30b of the second link plate 22.
- the first connecting member 12 is rotated about the hinge shaft 52 so that the first engaging portion 40 approaches the first engaged portion 30 a of the first link plate 21 .
- the first engaging portion 40 of the first connecting member 12 is inserted into the first notch 31 in the first engaged portion 30 a of the first link plate 21 .
- the inner protrusion 43 of the hanging wall 42 of the first connecting member 12 engages from the outside with the outer protrusion 32a in the second notch 32 of the first engaged portion 30a of the first link plate 21, thereby preventing the first engaging portion 40 from coming off the engaged portion 30.
- the inclined surface 32b of the outer convex portion 32a comes into contact with the inclined surface 43a of the inner convex portion 43, reducing the resistance during engagement.
- the horizontal surface 32c of the outer convex portion 32a comes into contact with the parallel surface 43b of the inner convex portion 43, making it difficult to release the engagement.
- the curved portion 41 of the first engaging portion 40 abuts against the lower end of the first notch 31 of the first engaged portion 30a. In other words, the curved portion 41 of the first engaging portion 40 abuts against the outer convex portion 32a of the second notch 32. By the curved portion 41 of the first engaging portion 40 abutting against the outer convex portion 32a of the second notch 32, rattling of the first connecting member 12 is suppressed.
- the upper surface which is the outer surface of the outwardly protruding wall 44 of the first connecting member 12, is located below the upper end of the first link plate 21.
- the tip of the outwardly protruding wall 44 at the first engagement portion 40 does not protrude from the outer surface of the first link plate 21 in the thickness direction of the first link plate 21, but is flush with the outer surface.
- the materials of the link plate 11, the first connecting member 12, and the second connecting member 13 that constitute the guide device 10 are not particularly limited.
- resin or metal can be used as the material for these members.
- the outwardly protruding wall 44 is easily visible from the outside of the link 20, so an operator can easily recognize that the outwardly protruding wall 44 is a portion for applying stress to remove the first connecting member 12. Furthermore, the presence of the outwardly protruding wall 44 makes it easier for an operator to apply stress upward using a finger or a tool, so that the first engaging portion 40 can be easily released from its engaged state.
- the link 20 further has a third notch 33 on the outside thereof as a release recess into which a tool or finger can be inserted when removing the first engaging portion 40 from the first engaged portion 30a of the first link plate 21. Therefore, as shown in Figure 11, the first engaging portion 40 can be released from its engaged state by inserting a tool or finger in the direction along the inclined surface 33a of the third notch 33 (the direction of arrow C).
- the third notch 33 has an inclined surface 33a that is inclined outwardly and downwardly.
- the width of the third notch 33 along the serial direction X is smaller than the width of the hanging wall 42 and the inward protrusion 43 of the first connecting member 12 along the serial direction X.
- the width of the third notch 33 along the serial direction X is smaller than the width of the second notch 32 along the serial direction X.
- the third notch 33 has an inclined surface 33a that is inclined outwardly and downwardly, the position of the third notch 33 can be easily recognized by the worker.
- the width of the third notch 33 is small, the position of the third notch 33 can be more easily recognized by the worker when viewing the link 20 from the outside. Therefore, the worker can easily insert a jig or a finger into the third notch 33 to release the engagement state of the first engagement portion 40.
- the first engaging portion 40 of the first connecting member 12 has a hanging wall 42 extending in the thickness direction of the main body portion 12a, an inward convex portion 43 provided on the hanging wall 42 and engaging with the outward convex portion 32a of the first link plate 21, and an outward protruding wall 44 that protrudes outward further than the hanging wall 42.
- the engagement when disengaging the inward convex portion 43 of the first engagement portion 40 from the outward convex portion 32a of the first link plate 21, the engagement can be easily released by displacing the outward protruding wall 44 of the first engagement portion 40 upward using a finger or a jig.
- the outward protruding wall 44 is easily visible from the outside of the link 20, the worker can easily displace the outward protruding wall 44 to disengage the first engagement portion 40.
- the first engagement portion 40 has a curved portion 41 between the hanging wall 42 and the main body portion 12a. By having the curved portion 41, it becomes easier to bend the curved portion 41 and displace the outwardly protruding wall 44, making it easier to release the engagement state of the first engagement portion 40.
- the first engaged portion 30a has a third notch (removal recess) 33 on its outer surface into which a tool or finger can be inserted to release the engagement between the outer convex portion 32a and the inner convex portion 43. Therefore, the engagement of the first engaging portion 40 can also be released by inserting a tool or finger into the third notch (removal recess) 33. Because the worker can select the method for releasing the engagement of the first engaging portion 40, the worker can perform the work efficiently in a method that suits him or her.
- the third notch (release recess) 33 has an inclined surface 33a that is inclined diagonally downward outward. This makes it easier for an operator to recognize the position of the third notch (release recess) 33, and therefore makes it easier for the operator to insert a tool or finger into the third notch (release recess) 33 to release the engagement state of the first engagement portion 40.
- the width of the third notch (release recess) 33 along the serial direction X is smaller than the width of the hanging wall 42 and the inward protrusion 43 of the first connecting member 12 along the same direction.
- the position of the third notch 33 can be more easily recognized by the worker. This makes it easier for the worker to insert a tool or finger into the third notch 33 to release the engagement state of the first engagement portion 40.
- the small width of the third notch 33 can prevent other members from being mistakenly inserted into the third notch 33.
- the outer surface of the outwardly protruding wall 44 of the first connecting member 12 is located lower than the outer surface of the main body 12a of the first connecting member 12 and the upper end of the first link plate 21. Therefore, as shown in FIG. 9, it is possible to prevent other members from interfering with the outwardly protruding wall 44 from above the link 20.
- the pair of link plates 11 are symmetrical. When attaching the first connecting member 12 to the pair of link plates 11, the first connecting member 12 can be attached without having to worry about the left-right orientation of the first connecting member 12, which improves work efficiency.
- the outer surface of the outwardly protruding wall 44 of the first connecting member 12 is not limited to being located lower than the outer surface of the main body portion 12 a of the first connecting member 12 . 12, for example, the outer surface of the outwardly protruding wall 44 of the first connecting member 12 may be flush with the outer surface of the main body portion 12a of the first connecting member 12. Also, the outer surface of the outwardly protruding wall 44 may be located above the outer surface of the main body portion 12a of the first connecting member.
- the shape of the curved portion 41 of the first engagement portion 40 of the first connecting member 12 is not limited to the shape of this embodiment. 13, for example, the curved portion 41 may be crank-shaped, protruding from one end of the main body 12a in the longitudinal direction of the main body 12a, then curving downward and then curving outward.
- the number of crank-shaped curved portions is not limited to two, and may be three or more.
- the curved portion 41 of the first engagement portion 40 of the first connecting member 12 may be omitted.
- the first engagement portion 40 of the first connecting member 12 may be provided with a straight portion 45 extending linearly along the longitudinal direction of the main body portion 12a between one end of the main body portion 12a and the hanging wall 42.
- the first engaging portion 40 of the first connecting member 12 has an inner convex portion 43 as an inner engaging portion at the lower end of the hanging wall 42, and the first engaged portion 30a of the first link plate 21 has an outer convex portion 32a as an outer engaged portion, but this is not limited to this aspect. As long as the inner engaging portion and the outer engaged portion can engage in a convex-concave relationship, either one may be a concave portion.
- the width of the third notch 33 along the serial direction X is configured to be smaller than the width of the inner protrusion 43 of the first engagement portion 40 along the same direction, but this is not limited to this aspect.
- the width of the third notch 33 along the serial direction X may be the same as the width of the inner protrusion 43 along the same direction. In other words, the width of the third notch 33 along the serial direction X may be the same as the width of the second notch 32 along the same direction.
- the inclined surface 33a of the third notch 33 is not limited to being inclined diagonally downward outward from the center of the second notch 32 in the serial direction X.
- the inclined surface 33a of the third notch 33 may be inclined diagonally downward outward from either end of the second notch 32 in the serial direction X.
- the inclined surface 33 a may be omitted from the third cutout 33.
- the third cutout 33 may be cut out along the thickness direction of the link plate 11.
- the third notch 33 serving as the release recess may be omitted.
- the tip of the outwardly protruding wall 44 of the first engagement portion 40 may protrude from the outer surface of the first link plate 21 in the thickness direction of the first link plate 21, or may be located inside the outer surface of the first link plate 21.
- first engaged portion 30a and the second engaged portion 30b of the pair of link plates 11 both have the outer convex portion 32a and the hinge bearing portion 31a, but this is not limited to this aspect.
- the first engaged portion 30a and the second engaged portion 30b may have the outer convex portion 32a but omit the hinge bearing portion 31a.

Abstract
Description
図15に示すように、エネルギー導通チェーン80は、対向する一対のリンクプレート81と、一対のリンクプレート81を一体に結合する連結片82とによってリンク83が形成されている。また、一対のリンクプレート81に、保持板84が架け渡されている。一対のリンクプレート81、連結片82、及び保持板84で囲まれた空間内にケーブルやホース等のエネルギー導通体を配置している。
図1、2に示すように、長尺物の案内装置(以下、案内装置ともいう。)10は、複数のリンク20を備えている。各リンク20は、対向する一対のリンクプレート11と、一対のリンクプレート11同士を連結する第1連結部材12と、一対のリンクプレート11同士を連結する第2連結部材13と、を備えている。案内装置10は、複数のリンク20が互いに回動自在に直列に連結されている。
図1に示すように、複数のリンク20が直線的に延びた箇所を基準にして、直列方向Xと幅方向Yの両方に直交する方向を上下方向Zとする。
<リンクプレート>
図2に示すように、リンクプレート11は、直列方向Xに長い板状に構成されている。リンクプレート11における直列方向Xの両端部は、直列方向Xの両外側が凸となる半円形状となっている。
リンクプレート11は、直列方向Xの中央部における上下方向Zの下端部に、第2連結部材13が係合する被係合部を有する。この被係合部については説明を省略する。第2連結部材13は、一対のリンクプレート11の両方に接続されている。第2連結部材13によって、一対のリンクプレート11の下端部同士が連結される。
図2に示すように、第2リンクプレート22は、直列方向Xにおける中央部よりも前方側に、貫通孔23を有する。第2リンクプレート22は、直列方向Xにおける中央部よりも後方側に、第2リンクプレート22の外側から内側に向かって厚さが薄くなった外側薄肉部24を有する。外側薄肉部24の前方側の縁部は、前方側に凸となる曲線状になっている。
図2に示すように、内側薄肉部28の形状は、第2リンクプレート22の直列方向Xの中央部において、上下方向Zに延びる回転軸線Pを想定して、回転軸線Pを中心に第2リンクプレート22を180°回転した際の外側薄肉部24と同じ形状を有している。すなわち、内側薄肉部28は、リンク20の内方側に、矩形凸部26と扇形凹部27を有しており、外側薄肉部24における軸部25の位置に貫通孔23を有している。
<リンクプレートの被係合部>
図2に示すように、リンクプレート11は、直列方向Xの中央部における上端部に、第1連結部材12が係合する被係合部30を有する。具体的には、一対のリンクプレート11のうち第1リンクプレート21は、第1連結部材12の第1係合部40が係合する第1被係合部30aを有する。一対のリンクプレート11のうち第2リンクプレート22は、第1連結部材12の第2係合部50が係合する第2被係合部30bを有する。したがって、一対のリンクプレート11のうち一方は、第1連結部材12の第1係合部40が係合する第1被係合部30aを有する。一対のリンクプレート11のうち他方は、第1連結部材12の第2係合部50が係合する第2被係合部30bを有する。
図5に示すように、第2被係合部30bは、第2リンクプレート22の上端部から下方に向かって切り欠かれた切欠としての第1切欠31を有する。第1切欠31は、第2リンクプレート22を厚さ方向に貫通している。第1切欠31の深さ、すなわち、第1切欠31の上下方向Zの長さは、第1連結部材12の本体部12aの厚さに略等しい。
図7に示すように、外方凸部32aは、外方斜め下に向かって傾斜する傾斜面32bを有している。また、外方凸部32aは、傾斜面32bの下方に、第2リンクプレート22の厚さ方向に沿って延びる水平面32cを有している。
図3、4に示すように、第1連結部材12は、板状の本体部12aと、第1リンクプレート21の第1被係合部30aに係合する第1係合部40と、第2リンクプレート22の第2被係合部30bに係合する第2係合部50とを有している。
図2、3に示すように、本体部12aは、板面が直列方向Xに沿うとともに、幅方向Yに長尺状に延びている。
(第1係合部)
第1係合部40は、本体部12aの長手方向の一端から延びる湾曲部41と、湾曲部41の外方側の端部から本体部12aの厚さ方向に沿って下方に延びる垂下壁42と、垂下壁42の上端部から外方に突出する外方突出壁44とを有している。
図10に示すように、内方凸部43は、内方斜め上方に向かって傾斜した傾斜面43aを有している。また、内方凸部43は、傾斜面43aの上方に、本体部12aの長手方向に平行に延びる平行面43bを有している。
図8に示すように、直列方向Xに沿う第1係合部40の長さ、すなわち、直列方向Xに沿う湾曲部41、垂下壁42、内方凸部43、及び外方突出壁44の幅は、同方向に沿う第2切欠32の幅より若干小さい。
図3、4に示すように、第2係合部50は、本体部12aの長手方向の他端部から外方に突出する突出片51と、突出片51の先端から本体部12aの短手方向の両側に突出するヒンジ軸52とを有する。ヒンジ軸52の横断面は円形状になっている。
図2に示すように、第2連結部材13は、長尺状の板材で構成されている。第2連結部材13は、一対のリンクプレート11の下端部同士を連結している。幅方向Yからリンク20を見た際に、第2連結部材13は、上下方向Zにおいて第1連結部材12に重なる位置に取り付けられている。
図6に示すように、一対のリンクプレート11に第1連結部材12を取り付ける際には、まず、第1連結部材12の第2係合部50のヒンジ軸52を、第2リンクプレート22の第2被係合部30bにおけるヒンジ軸受部31aに外方側から挿入する。
図9に示すように、第1連結部材12の第1係合部40が、第1リンクプレート21の第1被係合部30aにおける第1切欠31に挿入される。
本実施形態の案内装置10の作用について説明する。
図9、11に示すように、案内装置10は、リンク20の内方に位置する長尺物が収容された空間から、第1連結部材12に対して上方に応力(矢印B)が加わることがある。例えば、案内装置10に収容された長尺物が、案内装置10の動きに追従できないときや、案内装置10の収容空間に余裕がないときに、上記応力が加わることがある。この応力が加わると、第1連結部材12の長手方向の中央側が上方に変位しやすくなる。
(1)第1連結部材12の第1係合部40は、本体部12aの厚さ方向に延びる垂下壁42と、垂下壁42に設けられて第1リンクプレート21の外方凸部32aに係合する内方凸部43と、垂下壁42よりも外方に突出する外方突出壁44とを有している。
本実施形態は、以下のように変更して実施することができる。本実施形態及び以下の変更例は、技術的に矛盾しない範囲で互いに組み合わせて実施することができる。
図12に示すように、例えば、第1連結部材12の外方突出壁44の外表面は、第1連結部材12の本体部12aの外表面と面一であってもよい。また、第1連結部材の本体部12aの外表面より上方に位置してもよい。
図13に示すように、例えば、湾曲部41はクランク状であって、本体部12aの一端部から本体部12aの長手方向に突出した後、下方に向かって湾曲し、さらに外方に向かって湾曲して延びていてもよい。また、クランク状に湾曲した箇所は2箇所に限定されず、3箇所以上であってもよい。
図14に示すように、例えば、第1連結部材12の第1係合部40において、本体部12aの一端部と垂下壁42との間に、本体部12aの長手方向に沿って直線状に延びる直線部45を備えていてもよい。
・解除用凹部としての第3切欠33は省略されていてもよい。
