この場合、左右二本のロープを配電柱等に交互に回しかけ、上移動または下移動できるものが考えられている(特許第6055582号公報)。ところが、右のロープの右端の連結箇所(容易着脱部)と左のロープの右端の連結箇所(困難着脱部)は接近しているため、右のロープの右端の連結箇所(容易着脱部)と左のロープの右端の連結箇所(困難着脱部)の両連結箇所の間に道具を係止したりして、装着体の外面などを有効に使うことができなかった。これはロープやその他の道具が邪魔になるためである。これは反対側の左側でも同様であった。 In this case, it is considered that two ropes on the left and right can be alternately rotated around a utility pole or the like to move up or down (Patent No. 60555582). However, since the connection point at the right end of the right rope (easy attachment / detachment part) and the connection point at the right end of the left rope (difficult attachment / detachment part) are close to each other, the connection point at the right end of the right rope (easy attachment / detachment part) The outer surface of the wearing body could not be used effectively because the tool was locked between the two connecting points (difficult to attach / detach part) at the right end of the left rope. This is because ropes and other tools get in the way. This was also the case on the opposite left side.

上記課題を解決するため、本発明の安全装置では、装着体の右側に取り付けられ、一方の容易着脱部及び他方の困難着脱部が着脱自在に連結される右側連結体と、上記装着体の左側に取り付けられ、上記他方の上記容易着脱部及び上記一方の困難着脱部が着脱自在に連結される左側連結体とを備えた。 In order to solve the above problems, in the safety device of the present invention, a right side connecting body that is attached to the right side of the mounting body and one easy attachment / detachment portion and the other difficult attachment / detachment portion are detachably connected, and the left side of the mounting body. It is provided with a left side connecting body to which the other easy attachment / detachment portion and the one difficult attachment / detachment portion are detachably connected.

これにより、一方の容易着脱部及び他方の困難着脱部が右側連結体の一箇所に連結され、他方の容易着脱部及び一方の困難着脱部が左側連結体の一箇所に連結されるので、それぞれの容易着脱部及び困難着脱部の間がロープなどで覆い隠されたり邪魔になることがなくなり、装着体の外面などを有効に使うことができる。 As a result, one easy attachment / detachment part and the other difficult attachment / detachment part are connected to one place of the right side coupling, and the other easy attachment / detachment part and one difficult attachment / detachment part are connected to one place of the left side connection. The space between the easy / detachable part and the difficult / detachable part is not obscured or obstructed by a rope or the like, and the outer surface of the wearing body can be effectively used.

The hooks 16 and 17 (difficult to attach / detach portion) are connected to the expansion / contraction adjusters 9 and 10, and the hooks 16 and 17 are detachably engaged with the right side connecting body 41 or the left side connecting body 42.

(2)伸縮調節器9、10及びフック16、17(困難着脱部)
図2は、伸縮調節器9、10及びフック16、17(困難着脱部)の構造を示す。図2(a)は作業者Mの左側の伸縮調節器9を作業者Mの外側から見た状態を示す。右側の伸縮調節器9は、図2(a)の状態を左右線対称にした構造となる。なお、図2(a)は作業者Mの右側の伸縮調節器9を作業者Mの内側から見た状態を示すものであってもよい。
(2) Expansion and contraction adjusters 9, 10 and hooks 16 and 17 (difficult attachment / detachment part)
FIG. 2 shows the structures of the expansion / contraction adjusters 9, 10 and the hooks 16 and 17 (difficult attachment / detachment portions). FIG. 2A shows a state in which the expansion / contraction adjuster 9 on the left side of the worker M is viewed from the outside of the worker M. The expansion / contraction controller 9 on the right side has a structure in which the state shown in FIG. 2A is symmetrical with respect to the left and right lines. Note that FIG. 2A may show a state in which the expansion / contraction adjuster 9 on the right side of the worker M is viewed from the inside of the worker M.

この伸縮調節器9、10は、ステンレス等の金属製で、この伸縮調節器9、10の端に連結された上記フック16、17は断面「J字状」で、フック16、17の根元に板状の開閉部25、25が回動可能/搖動可能に取り付けられる。この開閉部25、25は、外に向かってバネ付勢されて、これによりこの「J字状」の中を塞いでいる。この開閉部25、25のバネ付勢方向は、本安全装置1が装着されたときには、作業者Mの外側方向となる。 The expansion / contraction adjusters 9 and 10 are made of metal such as stainless steel, and the hooks 16 and 17 connected to the ends of the expansion / contraction adjusters 9 and 10 have a "J-shaped" cross section and are attached to the bases of the hooks 16 and 17. The plate-shaped opening / closing portions 25, 25 are rotatably / swingably attached. The opening / closing portions 25, 25 are spring-loaded toward the outside, thereby closing the inside of the "J-shape". The spring urging direction of the opening / closing portions 25, 25 is the outward direction of the operator M when the safety device 1 is attached.

このフック16、17の開閉部25、25を押して、右側連結体41または左側連結体42を押しこむと、右側連結体41または左側連結体42の環がフック16、17内に入り込み、ロープ7、8の伸縮調節器9、10のフック16、17が、安全帯2/副帯3の右側連結体41または左側連結体42に着脱自在に係合される。 When the opening / closing portions 25, 25 of the hooks 16 and 17 are pushed to push the right side connecting body 41 or the left side connecting body 42, the ring of the right side connecting body 41 or the left side connecting body 42 enters the hooks 16 and 17, and the rope 7 The hooks 16 and 17 of the expansion / contraction adjusters 9 and 10 of 8 and 8 are detachably engaged with the right side connecting body 41 or the left side connecting body 42 of the safety belt 2 / auxiliary band 3.

図2(b)に示すように、開閉部25、25の先端は、「J字状」の中に深く入り込んでいるので、右側連結体41または左側連結体42が通る隙間/遊びが小さく、フック16、17から右側連結体41または左側連結体42が外れにくい。 As shown in FIG. 2B, since the tips of the opening / closing portions 25, 25 are deeply inserted into the "J-shape", the gap / play through which the right side connecting body 41 or the left side connecting body 42 passes is small. The right side connecting body 41 or the left side connecting body 42 is hard to come off from the hooks 16 and 17.

したがって、フック16、17と右側連結体41または左側連結体42とが安全帯2/副帯3(装着体)に装着された状態のときのフック16、17と右側連結体41または左側連結体42との間、つまり困難着脱部自身内の遊び/隙間は少なく、フック16、17は右側連結体41または左側連結体42から容易に外れない。なお、開閉部25、25はフック16、17内に向かって延出されてもよく、これにより、右側連結体41または左側連結体42が、開閉部25、25とフック16、17との間に挟まれない。 Therefore, when the hooks 16 and 17 and the right side connecting body 41 or the left side connecting body 42 are attached to the safety belt 2 / auxiliary band 3 (attached body), the hooks 16 and 17 and the right side connecting body 41 or the left side connecting body 41 or the left side connecting body are attached. There is little play / gap between the hooks 16 and 42, that is, within the difficult attachment / detachment portion itself, and the hooks 16 and 17 do not easily come off from the right side connection 41 or the left side connection 42. The opening / closing portions 25, 25 may extend toward the inside of the hooks 16 and 17, whereby the right side connecting body 41 or the left side connecting body 42 is placed between the opening / closing parts 25, 25 and the hooks 16 and 17. Not sandwiched between.

この伸縮調節器9、10は、二つの金属部材を連結した構造になっている。下部の金属部材は、操作部33となっており、操作部33の端部に上記フック16、17(困難着脱部)が連結されている。上部の金属部材は、ロープ7、8が挿通される断面U字形のロープホルダー31となっており、ロープホルダー31と操作部33とは、2つの連結リンク32、32で連結され、この連結リンク32、32の両端とロープホルダー31及び操作部33とは軸で連結されている。 The expansion / contraction adjusters 9 and 10 have a structure in which two metal members are connected. The lower metal member is an operation portion 33, and the hooks 16 and 17 (difficult attachment / detachment portions) are connected to the end portion of the operation portion 33. The upper metal member is a rope holder 31 having a U-shaped cross section through which the ropes 7 and 8 are inserted, and the rope holder 31 and the operation unit 33 are connected by two connecting links 32 and 32, and the connecting links are connected. Both ends of 32 and 32, the rope holder 31 and the operation unit 33 are connected by a shaft.

これにより、ロープホルダー31に対して操作部33が、ロープ7、8の長手方向に沿って揺動可能となっている。そして、操作部33をロープ7、8に沿って長手方向に移動させると、ロープ7、8がロープホルダー31内を摺動し、ロープ7、8の長さ/繰り出し量が調節される。 As a result, the operation unit 33 can swing with respect to the rope holder 31 along the longitudinal direction of the ropes 7 and 8. Then, when the operation unit 33 is moved in the longitudinal direction along the ropes 7 and 8, the ropes 7 and 8 slide in the rope holder 31 and the length / feeding amount of the ropes 7 and 8 is adjusted.

なお、図示しないが、連結リンク32、32の先端には、ロープ7、8に当接及び離間可能なストッパーが設けられている。伸縮調節器9、10が握られて、図2(a)でロープホルダー31に対して操作部33が左に動くと、操作部33がロープホルダー31に近づき、ストッパーがロープ7、8から離れ、ロープ7、8のスライド及び調整が可能となる。 Although not shown, the tips of the connecting links 32 and 32 are provided with stoppers capable of contacting and separating the ropes 7 and 8. When the expansion / contraction adjusters 9 and 10 are gripped and the operation unit 33 moves to the left with respect to the rope holder 31 in FIG. 2A, the operation unit 33 approaches the rope holder 31 and the stopper separates from the ropes 7 and 8. , Rope 7 and 8 can be slid and adjusted.

伸縮調節器9、10の握りが解除されて、図2(a)でロープホルダー31に対して操作部33が右に動くと、操作部33がロープホルダー31から離れ、ストッパーがロープ7、8に当接して、ロープ7、8が伸縮調節器9、10に対して動かなくなる。 When the grips of the expansion / contraction adjusters 9 and 10 are released and the operation unit 33 moves to the right with respect to the rope holder 31 in FIG. 2A, the operation unit 33 separates from the rope holder 31 and the stoppers move to the ropes 7 and 8. The ropes 7 and 8 get stuck with respect to the expansion and contraction adjusters 9 and 10.

作業中には、ロープ7、8及びロープホルダー31が安全帯2/副帯3に対して引っ張られるので、図2(a)でロープホルダー31に対して操作部33が右に動く状態となり、ストッパーが機能して、作業中にはロープ7、8の長さ/繰り出し量の調整は禁止される。 During the work, the ropes 7 and 8 and the rope holder 31 are pulled with respect to the safety belt 2 / sub-belt 3, so that the operation unit 33 moves to the right with respect to the rope holder 31 in FIG. 2A. The stopper functions, and adjustment of the length / extension amount of the ropes 7 and 8 is prohibited during the work.

(3)容易着脱器11、12(容易着脱部)
図3は安全装置1のフック11(12)を示す。ロープ7、8のもう一端には、フック11、12(容易着脱部)が設けられている。フック11、12は、スチール製、同形同大で、図3に示すように、ナス環構造からなっている。ナス環の開閉部18、18はフック11、12の外方にバネ付勢されており、開閉部18、18が環の内側に開かれ、これにより、ナス環構造のフック11、12が開かれる。
(3) Easy attachment / detachment devices 11 and 12 (easy attachment / detachment part)
FIG. 3 shows the hook 11 (12) of the safety device 1. Hooks 11 and 12 (easy attachment / detachment portions) are provided at the other ends of the ropes 7 and 8. The hooks 11 and 12 are made of steel, have the same shape and the same size, and have an eggplant ring structure as shown in FIG. The opening / closing portions 18 and 18 of the eggplant ring are spring-loaded to the outside of the hooks 11 and 12, and the opening / closing portions 18 and 18 are opened inside the ring, whereby the hooks 11 and 12 of the eggplant ring structure are opened. Is done.

このフック11、12の開閉部18、18を押して、右側連結体41または左側連結体42を押しこむと、右側連結体41または左側連結体42の環がフック11、12内に入り込み、ロープ7、8のフック11、12が、安全帯2/副帯3の右側連結体41または左側連結体42に着脱自在に係合される。 When the opening / closing portions 18 and 18 of the hooks 11 and 12 are pushed and the right side connecting body 41 or the left side connecting body 42 is pushed in, the ring of the right side connecting body 41 or the left side connecting body 42 enters the hooks 11 and 12 and the rope 7 , 8 hooks 11 and 12 are detachably engaged with the right side connecting body 41 or the left side connecting body 42 of the safety belt 2 / sub band 3.

図3に示すように、開閉部18、18と、フック11、12のナス環の環部との間の隙間/遊びが大きいので、右側連結体41または左側連結体42が通る隙間/遊びが大きく、フック11、12から右側連結体41または左側連結体42を外し易い。 As shown in FIG. 3, since the gap / play between the opening / closing portions 18 and 18 and the ring portion of the eggplant ring of the hooks 11 and 12 is large, the gap / play through which the right side connecting body 41 or the left side connecting body 42 passes is large. It is large and it is easy to remove the right side connecting body 41 or the left side connecting body 42 from the hooks 11 and 12.

したがって、フック11、12と右側連結体41または左側連結体42とが安全帯2/副帯3(装着体)に装着された状態のときのフック11、12と右側連結体41または左側連結体42との間、つまり容易着脱部自身内の遊び/隙間は多く、フック11、12は右側連結体41または左側連結体42から外し易い。 Therefore, when the hooks 11 and 12 and the right side connecting body 41 or the left side connecting body 42 are attached to the safety belt 2 / auxiliary band 3 (wearing body), the hooks 11 and 12 and the right side connecting body 41 or the left side connecting body are connected. There is a lot of play / gap between the hooks 11 and 42, that is, in the easily detachable portion itself, and the hooks 11 and 12 can be easily removed from the right side connecting body 41 or the left side connecting body 42.

この外し易いというのは、上記伸縮調節器9、10のフック16、17と右側連結体41または左側連結体42との係合に比べてという意味であり、フック11、12が右側連結体41または左側連結体42から不用意に外れるという意味ではなく、安全性は保たれる。なお、「ナス環」は「茄子鐶」というが、便宜上「ナス環」の語を使う。 This easy removal means that the hooks 16 and 17 of the expansion / contraction adjusters 9 and 10 are compared with the engagement between the right side connecting body 41 or the left side connecting body 42, and the hooks 11 and 12 are the right side connecting body 41. Or, it does not mean that it is inadvertently disconnected from the left side connecting body 42, and safety is maintained. The word "eggplant ring" is called "eggplant ring", but the word "eggplant ring" is used for convenience.

(4)右側連結体41及び左側連結体42
図7及び図8は上記安全帯2(装着体)に取り付けられている右側連結体41及び左側連結体42を示す。右側連結体41は安全帯2(装着体)の右側に取り付けられ、左側連結体42は安全帯2(装着体)の左側に取り付けられる。左側連結体42は右側連結体41と対称つまり同一の形状をなしているので、右側連結体41を代表して説明する。
(4) Right side connecting body 41 and left side connecting body 42
7 and 8 show the right side connecting body 41 and the left side connecting body 42 attached to the safety belt 2 (mounting body). The right side connector 41 is attached to the right side of the safety belt 2 (mounting body), and the left side connecting body 42 is attached to the left side of the safety belt 2 (mounting body). Since the left side connecting body 42 has a symmetrical shape, that is, the same shape as the right side connecting body 41, the right side connecting body 41 will be described as a representative.

この安全帯2の右側連結体41及び左側連結体42が係合固定される箇所それぞれには、「横日」型の留め金具43が挿通されている。留め金具43は板状のバックル形状をしており、「横日」型で2つの縦穴44、44が形成され、この2つの縦穴44、44を、帯状の安全帯2が挿通している。 A "horizontal sun" type fastener 43 is inserted in each of the places where the right side connecting body 41 and the left side connecting body 42 of the safety belt 2 are engaged and fixed. The fastener 43 has a plate-shaped buckle shape, and two vertical holes 44, 44 are formed in a “horizontal sun” shape, and the band-shaped safety belt 2 inserts the two vertical holes 44, 44 through the two vertical holes 44, 44.

この縦穴44、44の間の安全帯2には、されに右側連結体41が挿通されている。右側連結体41は、ほぼ台形形状の枠状をしており、この台形枠の平行な二辺のうち長い方の下底にあたる基底辺45で、右側連結体41内に上記安全帯2が挿通されて安全帯2(装着体)に連結されている。 A right side connecting body 41 is inserted into the safety belt 2 between the vertical holes 44 and 44. The right side connecting body 41 has a substantially trapezoidal frame shape, and the safety belt 2 is inserted into the right side connecting body 41 at the base side 45 which is the longer lower base of the two parallel sides of the trapezoidal frame. It is connected to the safety belt 2 (attached body).

安全帯2を引っ張って緊縮すると、右側連結体41の基底辺45が留め金具43に当接され、右側連結体41及び留め金具43が、安全帯2にしっかりと緊縮され、安全帯2に対して右側連結体41が容易に移動しないよう動かないように固定される。 When the safety belt 2 is pulled and tightened, the base side 45 of the right side connecting body 41 is brought into contact with the fastener 43, and the right side connecting body 41 and the fastener 43 are firmly tightened by the safety belt 2 with respect to the safety belt 2. The right side connecting body 41 is fixed so as not to move easily.

右側連結体41の基底辺45の上下両端はほぼ直角に折れ曲がり、上下平行に延びて水平部46、46が形成され、次いで先端に向かって斜めに傾斜し、上記安全帯2(装着体)側より先端に向かって細くなっていて、傾斜部47、48が形成されている。 The upper and lower ends of the base side 45 of the right side connecting body 41 are bent at a substantially right angle, extend vertically in parallel to form horizontal portions 46 and 46, and then incline diagonally toward the tip to the safety belt 2 (attached body) side. It becomes thinner toward the tip, and inclined portions 47 and 48 are formed.

この上下一対の傾斜部47、48は、上記安全帯2(装着体)側より先端に向かって下方の傾斜部47が上へ向かって傾斜しており、上方の傾斜部48が下へ向かって傾斜している。この下方の傾斜部47には、上記フック(困難着脱部)16または/及び(困難着脱部)17が着脱自在に係合される。 In the pair of upper and lower inclined portions 47, 48, the lower inclined portion 47 is inclined upward toward the tip from the safety belt 2 (mounting body) side, and the upper inclined portion 48 is inclined downward. It is tilted. The hook (difficult attachment / detachment portion) 16 and / and (difficult attachment / detachment portion) 17 are detachably engaged with the lower inclined portion 47.

右側連結体41には、配電柱(柱状構造物)21を周回して一方の右側のフック(困難着脱部)17が着脱自在に係合され、左側連結体42には、配電柱(柱状構造物)21を周回して他方の左側のフック(困難着脱部)16が着脱自在に係合される。 A hook (difficult attachment / detachment portion) 17 on one right side is detachably engaged with the right side connector 41 around a power distribution pole (columnar structure) 21, and a power distribution pole (columnar structure) is engaged with the left side connection 42. The other left hook (difficult attachment / detachment portion) 16 is detachably engaged with the object) 21 orbiting.

水平部46、46または傾斜部47、48の直線状の水平または傾斜の長さは、フック(困難着脱部)16、17の幅、長さより長いので、フック(困難着脱部)16、17は、水平部46、46または傾斜部47、48に安定して係合、係合位置が不用意に動かず作業者Mの作業に都合がよい。 Since the length of the linear horizontal or inclined portion 46, 46 of the horizontal portion 46, 46 or the inclined portion 47, 48 is longer than the width and length of the hook (difficult attachment / detachment portion) 16, 17, the hook (difficult attachment / detachment portion) 16, 17 is , Stable engagement with horizontal portions 46, 46 or inclined portions 47, 48, and the engagement position does not move carelessly, which is convenient for the work of the operator M.

ただし、ロープ7、8に体重を掛けたときには、フック(困難着脱部)16、17は、傾斜部47、48に位置し、ロープ7、8に体重を掛けないときには、フック(困難着脱部)16、17は、水平部46、46に移動することもある。 However, when the weight is applied to the ropes 7 and 8, the hooks (difficult to attach / detach part) 16 and 17 are located at the inclined portions 47 and 48, and when the weight is not applied to the ropes 7 and 8, the hooks (difficult to attach / detach part) are located. 16 and 17 may move to the horizontal portions 46 and 46.

右側連結体41の先端は、上記傾斜部47、48から互いに合流するように折れ曲がり、合流して縦向きの先端底辺49が形成されている。傾斜部47、48が傾斜しているので、先端底辺49は上記基底辺45より短い。したがって、先端底辺49の長さが短くなり、後述するフック(容易着脱部)11、12の移動範囲が小さくなり、作業者Mの作業に都合がよい。 The tip of the right side connecting body 41 is bent so as to merge with each other from the inclined portions 47 and 48, and merges to form a vertically oriented tip base 49. Since the inclined portions 47 and 48 are inclined, the tip bottom side 49 is shorter than the base side 45. Therefore, the length of the tip base 49 is shortened, and the moving range of the hooks (easily attached / detached portions) 11 and 12 described later is reduced, which is convenient for the work of the operator M.

この先端底辺49の中央内側は湾曲している、つまり上記安全帯2(装着体)側から突出した先端は、内側に向かって湾曲している。この湾曲によって、凹部50が形成されている。この先端底辺49には、上記フック(容易着脱部)11または/及びフック(容易着脱部)12が着脱自在に係合される。 The central inner side of the tip base 49 is curved, that is, the tip protruding from the safety belt 2 (attached body) side is curved inward. The concave portion 50 is formed by this curvature. The hook (easy attachment / detachment portion) 11 and / and the hook (easy attachment / detachment portion) 12 are detachably engaged with the tip bottom side 49.

右側連結体41には、配電柱(柱状構造物)21を周回して他方の左側のフック(容易着脱部)11が着脱自在に係合され、左側連結体42には、配電柱(柱状構造物)21を周回して一方の右側のフック(困難着脱部)12が着脱自在に係合される。 The right side connector 41 is circulated around the power distribution pole (columnar structure) 21 and the other left hook (easy attachment / detachment portion) 11 is detachably engaged with the right side connector 41, and the power distribution pole (columnar structure) is engaged with the left side connector 42. One right hook (difficult attachment / detachment portion) 12 is detachably engaged with the object) 21 orbiting.

先端底辺49には凹部50があるので、係合しているフック(容易着脱部)11、12は不容易に移動せず、凹部50に安定し易いので係合位置が不用意に動かず作業者Mの作業に都合がよい。先端底辺49は、上記フック(困難着脱部)16、17の幅、長さより小さい。 Since the tip bottom 49 has a recess 50, the hooks (easily attachable / detached portions) 11 and 12 that are engaged do not move easily, and the recess 50 is easy to stabilize, so that the engaging position does not move carelessly. It is convenient for the work of person M. The tip base 49 is smaller than the width and length of the hooks (difficult attachment / detachment portions) 16 and 17.

これにより、フック(困難着脱部)16、17が先端底辺49まで移動することが少なくなり、作業者Mの作業でフック(困難着脱部)16、17とフック(容易着脱部)11、12とを区別し易くなる。なお、先端底辺49はフック(困難着脱部)16、17の幅、長さより大きくてもよい。 As a result, the hooks (difficult to attach / detach part) 16 and 17 are less likely to move to the bottom of the tip 49, and the hooks (difficult to attach / detach part) 16 and 17 and the hooks (easy to attach / detach part) 11 and 12 are operated by the operator M. It becomes easy to distinguish. The tip base 49 may be larger than the width and length of the hooks (difficult to attach / detach parts) 16 and 17.

先端底辺49と傾斜部47のなす角度、折り曲げスペースが、フック(困難着脱部)16、17を通過させない角度、内部スペースでもよい。フック(困難着脱部)16、17が、傾斜部47から水平部46または先端底辺49へ移動するのに要は困難があればよい。なお、場合によって、このような困難はなくてもよい。 The angle formed by the tip base 49 and the inclined portion 47 and the bending space may be an angle that does not allow the hooks (difficult attachment / detachment portions) 16 and 17 to pass through, and an internal space. It suffices if there is difficulty in moving the hooks (difficulty attachment / detachment portions) 16 and 17 from the inclined portion 47 to the horizontal portion 46 or the tip base 49. In some cases, such difficulty may not be necessary.

ロープ7のフック(困難着脱部)16とフック(容易着脱部)11とは入れ替えて向きを変え、同じくロープ8のフック(困難着脱部)17とフック(容易着脱部)12とは入れ替えて向きを変えても同様のことができる。 The hook (difficult attachment / detachment part) 16 and the hook (easy attachment / detachment part) 11 of the rope 7 are exchanged to change the direction, and the hook (difficult attachment / detachment part) 17 and the hook (easy attachment / detachment part) 12 of the rope 8 are also exchanged and oriented. The same can be done by changing.

このように、右側連結体41は、上記安全帯2(装着体)の右側に取り付けられ、上記一方のフック(容易着脱部)11及び上記他方のフック(困難着脱部)17が着脱自在に連結され、左側連結体42は、上記安全帯2(装着体)の左側に取り付けられ、上記他方の上記フック(容易着脱部)12及び上記一方のフック(困難着脱部)16困難着脱部が着脱自在に連結される。 In this way, the right side connecting body 41 is attached to the right side of the safety belt 2 (mounting body), and the one hook (easy attachment / detachment portion) 11 and the other hook (difficult attachment / detachment portion) 17 are detachably connected. The left side connecting body 42 is attached to the left side of the safety belt 2 (mounting body), and the other hook (easy attachment / detachment portion) 12 and the one hook (difficult attachment / detachment portion) 16 difficult attachment / detachment portion are detachable. Is connected to.

上記右側連結体41と左側連結体42とは、同一形状で、扁平で凹凸が無く、表裏で同一形状である。これにより、右側連結体41と左側連結体42とを装着するとき、右側連結体41と左側連結体42とを区別する必要が無くなり、安全帯2(装着体)を装着する手間がかからない。また、右側連結体41(左側連結体42)を装着するとき、右側連結体41(左側連結体42)の表裏を区別する必要が無くなり、安全帯2(装着体)を装着する手間がかからない。 The right side connecting body 41 and the left side connecting body 42 have the same shape, are flat and have no unevenness, and have the same shape on the front and back sides. As a result, when the right side connecting body 41 and the left side connecting body 42 are attached, it is not necessary to distinguish between the right side connecting body 41 and the left side connecting body 42, and it is not necessary to attach the safety belt 2 (attached body). Further, when the right side connecting body 41 (left side connecting body 42) is attached, it is not necessary to distinguish the front and back sides of the right side connecting body 41 (left side connecting body 42), and it is not necessary to attach the safety belt 2 (attached body).

右側連結体41(左側連結体42)は、扁平で凹凸が無かったが、湾曲していてもよく、表裏で同一形状ではなく、表裏で形状が異なっていてもよく、右側連結体41(左側連結体42)の中央に向かってまたは周縁に向かって膨らんでいてもよいし、凹凸があってもよい。この場合、右側連結体41(左側連結体42)の表裏を区別する必要は生じる。 The right side connecting body 41 (left side connecting body 42) was flat and had no unevenness, but may be curved, may not have the same shape on the front and back sides, and may have different shapes on the front and back sides, and the right side connecting body 41 (left side connecting body 41). The connecting body 42) may bulge toward the center or toward the periphery, or may have irregularities. In this case, it becomes necessary to distinguish the front and back sides of the right side connecting body 41 (left side connecting body 42).

(5)安全装置1全体の平面
図4は安全装置1全体の概略図を示す。図4は安全装置1を上から見た状態を示す。図4に示すように、伸縮調節器9、10のフック16、17(困難着脱部)を、上記安全帯2/副帯3から外すときの操作位置、つまり開閉部25、25は、上記安全帯2/副帯3またはフック16、17自身で隠されている。
(5) Plan view of the entire safety device 1 FIG. 4 shows a schematic view of the entire safety device 1. FIG. 4 shows a state in which the safety device 1 is viewed from above. As shown in FIG. 4, the operating positions when the hooks 16 and 17 (difficult to attach / detach parts) of the expansion / contraction adjusters 9 and 10 are removed from the safety belt 2 / sub-band 3, that is, the opening / closing parts 25 and 25 are said to be safe. It is hidden by the belt 2 / sub-belt 3 or the hooks 16 and 17 themselves.

したがって、フック16、17が右側連結体41または左側連結体42から容易に外れなくなる。このため、ロープ7、8のフック16、17側の端部は、作業中に不用意に安全帯2/副帯3から外れることがなく、安全となる。 Therefore, the hooks 16 and 17 cannot be easily disengaged from the right side connecting body 41 or the left side connecting body 42. Therefore, the ends of the ropes 7 and 8 on the hooks 16 and 17 sides are not inadvertently detached from the safety belt 2 / sub-belt 3 during the work, and are safe.

また、開閉部25、25とフック16、17との間に右側連結体41または左側連結体42が挟まれて、開閉部25、25が動かなくなり、開閉部25、25の解除が禁止され作動しなくなることもある。この場合でも、フック16、17が右側連結体41または左側連結体42から容易に外れない。 Further, the right side connecting body 41 or the left side connecting body 42 is sandwiched between the opening / closing parts 25, 25 and the hooks 16, 17, and the opening / closing parts 25, 25 become immobile, and the opening / closing parts 25, 25 are prohibited from being released and operated. It may not be possible. Even in this case, the hooks 16 and 17 cannot be easily disengaged from the right side connecting body 41 or the left side connecting body 42.

なお、上述のように、開閉部25、25がフック16、17内に向かって延出されている場合には、この延出部が安全帯2/副帯3に当接して、開閉部25、25の解除が禁止され作動しなくなる。この場合でも、フック16、17が右側連結体41または左側連結体42から容易に外れない。 As described above, when the opening / closing portions 25, 25 extend toward the inside of the hooks 16 and 17, the extending portion abuts on the safety belt 2 / sub-band 3 and the opening / closing portion 25 , 25 is prohibited from being released and does not operate. Even in this case, the hooks 16 and 17 cannot be easily disengaged from the right side connecting body 41 or the left side connecting body 42.

この伸縮調節器9、10を、ロープ7、8に沿って長手方向に移動させ、これにより、フック11、12(容易着脱部)とフック16、17(困難着脱部)との間の長さ/繰り出し量を調節することができる。したがって、ロープ7、8が周回する配電柱21(柱状構造物)の大きさ、作業する人の作業のしやすさに合わせて、ロープ7、8及び安全帯2/副帯3によって形成される、ループ長・周回長の長さ(図4参照)を調節することができる。 The expansion / contraction adjusters 9 and 10 are moved in the longitudinal direction along the ropes 7 and 8, whereby the length between the hooks 11 and 12 (easy attachment / detachment portion) and the hooks 16 and 17 (difficult attachment / detachment portion) is long. / The amount of feeding can be adjusted. Therefore, the ropes 7 and 8 are formed by the ropes 7 and 8 and the safety belt 2 / sub-band 3 according to the size of the power distribution pole 21 (columnar structure) around which the ropes 7 and 8 circulate and the ease of work of the worker. , The length of the loop length and the circumference length (see FIG. 4) can be adjusted.

また、右側連結体41または左側連結体42は、安全帯2/副帯3を作業者Mが装着した状態で、安全帯2/副帯3上の作業する人の身体の左右のほぼ真横乃至横斜め前に位置する。つまり、2本のロープ7、8の2つのフック16、17(困難着脱部)は、上記作業する人の左右逆の対称の位置に設けられる。 Further, the right side connecting body 41 or the left side connecting body 42 is substantially right beside the left and right sides of the worker's body on the safety belt 2 / auxiliary belt 3 with the safety belt 2 / auxiliary belt 3 worn by the worker M. It is located diagonally forward. That is, the two hooks 16 and 17 (difficult attachment / detachment portions) of the two ropes 7 and 8 are provided at symmetrical positions opposite to each other on the left and right sides of the worker.

なお、ロー7とロープ8とを入れ替え、左の伸縮調節器9及びフック16と右の伸縮調節器10及びフック17とを入れ替えてもよい。これにより、開閉部25、25が作業者Mの内側に向き、安全帯2/副帯3側に向いて、開閉部25、25が安全帯2/副帯3で隠されて、しかも開閉部25、25の外側もフック16、17で隠される。したがって、伸縮調節器9、10のフック16、17が右側連結体41または左側連結体42から容易に外れなくなり、安全となる。 The rope 7 and the rope 8 may be exchanged, and the left expansion / contraction adjuster 9 and the hook 16 and the right expansion / contraction adjuster 10 and the hook 17 may be exchanged. As a result, the opening / closing portions 25, 25 face the inside of the worker M and face the safety belt 2 / sub-belt 3, and the opening / closing portions 25, 25 are hidden by the safety belt 2 / sub-belt 3, and the opening / closing portion. The outside of 25 and 25 is also hidden by hooks 16 and 17. Therefore, the hooks 16 and 17 of the expansion / contraction adjusters 9 and 10 cannot be easily disengaged from the right side connecting body 41 or the left side connecting body 42, which is safe.

右側連結体41または左側連結体42は、図4に示すように、バックル14を締め安全帯2/副帯3を装着した状態では、作業する人の体の中心に対してほぼ左右対称に位置する。そして、上記2本のロープ7、8の2つのフック11、12(容易着脱部)は、作業する人の左右逆の位置に設けられる。 As shown in FIG. 4, the right side connecting body 41 or the left side connecting body 42 is positioned substantially symmetrically with respect to the center of the worker's body when the buckle 14 is fastened and the safety belt 2 / auxiliary belt 3 is attached. To do. The two hooks 11 and 12 (easily attached / detached portions) of the two ropes 7 and 8 are provided at opposite positions on the left and right of the worker.

図4に示すように、作業者Mに安全帯2/副帯3を装着した状態では、左側のフック16(困難着脱部)から延びるロープ7は、配電柱21を周回して、安全帯2のバックル14の右側に設けられた右側連結体41に端部のフック11が係止される。 As shown in FIG. 4, when the safety belt 2 / auxiliary belt 3 is attached to the worker M, the rope 7 extending from the hook 16 (difficult attachment / detachment portion) on the left side goes around the power distribution pole 21 and the safety belt 2 The hook 11 at the end is locked to the right side connecting body 41 provided on the right side of the buckle 14.

同じく図4に示すように、作業者Mに安全帯2/副帯3を装着した状態では、右側のフック17(困難着脱部)から延びるロープ8は、配電柱21を周回して、安全帯2のバックル14の左側に設けられた右側連結体41に端部のフック12が係止される。 Similarly, as shown in FIG. 4, when the safety belt 2 / auxiliary belt 3 is attached to the worker M, the rope 8 extending from the hook 17 (difficult attachment / detachment portion) on the right side goes around the power distribution pole 21 and is a safety belt. The hook 12 at the end is locked to the right side connecting body 41 provided on the left side of the buckle 14 of 2.

なお、作業の途中では、例えば配電柱21を上下するとき、障害物23をこえるときなどには、ロープ7の両端部であるフック16(困難着脱部)、フック11(容易着脱部)とも左側の左側連結体42に一時的に係合されることもある。また、作業の途中では、例えば配電柱21を上下するとき、障害物23をこえるときなどには、ロープ8の両端部であるフック17(困難着脱部)、フック12(容易着脱部)とも右側の右側連結体41に一時的に係合されることもある。 In the middle of the work, for example, when the power distribution pole 21 is moved up and down, or when the obstacle 23 is crossed, both the hook 16 (difficult attachment / detachment portion) and the hook 11 (easy attachment / detachment portion), which are both ends of the rope 7, are on the left side. It may be temporarily engaged with the left side connecting body 42 of the. Further, in the middle of the work, for example, when the power distribution pole 21 is moved up and down, or when the obstacle 23 is crossed, the hooks 17 (difficult attachment / detachment portion) and the hook 12 (easy attachment / detachment portion) at both ends of the rope 8 are on the right side. It may be temporarily engaged with the right side coupling 41 of the.

このとき、左側の左側連結体42に一時的に係合されるフック11(容易着脱部)は、先端底辺49の凹部50ではなく、左側の水平部46に一時的に係止される。同様に、右側の右側連結体41に一時的に係合されるフック12(容易着脱部)は、先端底辺49の凹部50ではなく、右側の水平部47に一時的に係止される。 At this time, the hook 11 (easily attached / detached portion) temporarily engaged with the left left connecting body 42 on the left side is temporarily locked to the horizontal portion 46 on the left side instead of the recess 50 at the bottom end 49 of the tip. Similarly, the hook 12 (easily attached / detached portion) temporarily engaged with the right side connecting body 41 on the right side is temporarily locked to the horizontal portion 47 on the right side instead of the recess 50 at the bottom end 49 of the tip.

このとき1つの左側連結体42または右側連結体41に2つのフック11、12(容易着脱部)が係合されるが、フック11、12の係合位置が異なるので、フック11とフック12とを間違えてしまうことがない。この場合、左のフック11(容易着脱部)、左のフック16(困難着脱部)、左のロープ7と、右のフック12(容易着脱部)、右のフック17(困難着脱部)、右のロープ8とは、色が異なっている。 At this time, two hooks 11 and 12 (easy attachment / detachment portions) are engaged with one left side connecting body 42 or right side connecting body 41, but since the engaging positions of the hooks 11 and 12 are different, the hook 11 and the hook 12 Do not make a mistake. In this case, the left hook 11 (easy attachment / detachment part), the left hook 16 (difficult attachment / detachment part), the left rope 7, the right hook 12 (easy attachment / detachment part), the right hook 17 (difficult attachment / detachment part), and the right. The color is different from that of the rope 8.

つまり、上記一方のロープ7並びにこのロープ7の両端のフック16(困難着脱部)及びフック11(容易着脱部)と、上記他方のロープ8並びにこのロープ8の両端のフック12(容易着脱部)及びフック17(困難着脱部)17とは、色が異なっている。 That is, the one rope 7 and the hooks 16 (difficult attachment / detachment portion) and hooks 11 (easy attachment / detachment portion) at both ends of the rope 7 and the other rope 8 and the hooks 12 at both ends of the rope 8 (easy attachment / detachment portion). The color is different from that of the hook 17 (difficult to attach / detach part) 17.

これにより、同じ左側連結体42に一時的に係止されている2つのフック11、12(容易着脱部)のうち、左側連結体42に連結されているフック16(困難着脱部)と同じ色のフック11(容易着脱部)を外して右側連結体41に連結すればよい。同じく同じ右側連結体41に一時的に係止されている2つのフック11、12(容易着脱部)のうち、右側連結体41に連結されているフック17(困難着脱部)と同じ色のフック12(容易着脱部)を外して左側連結体42に連結すればよい。 As a result, of the two hooks 11 and 12 (easy attachment / detachment portion) temporarily locked to the same left side connection body 42, the same color as the hook 16 (difficult attachment / detachment portion) connected to the left side connection body 42. The hook 11 (easily attached / detached portion) may be removed and connected to the right side connecting body 41. Of the two hooks 11 and 12 (easy attachment / detachment part) temporarily locked to the same right side connection 41, the hook of the same color as the hook 17 (difficult attachment / detachment part) connected to the right side connection 41. 12 (easy attachment / detachment portion) may be removed and connected to the left side connecting body 42.

これにより、両ロープ7、8ともに配電柱(柱状構造物)21からはずれてしまうことがなくなり、必ずロープ7、8のうちすくなくとも一方が配電柱(柱状構造物)21を周回し安全を担保できる。また、フック12(容易着脱部)とフック16(困難着脱部)との間、フック11(容易着脱部)とフック17(困難着脱部)との間に安全帯2/副帯3が無くなりまたはロープ7、8で覆い隠されず、安全帯2/副帯3外面を有効に使用できる。 As a result, both ropes 7 and 8 do not come off from the utility pole (columnar structure) 21, and at least one of the ropes 7 and 8 always circulates around the utility pole (columnar structure) 21 to ensure safety. .. Further, the safety belt 2 / sub-band 3 disappears between the hook 12 (easy attachment / detachment portion) and the hook 16 (difficult attachment / detachment portion), and between the hook 11 (easy attachment / detachment portion) and the hook 17 (difficult attachment / detachment portion). The outer surface of the safety belt 2 / sub-belt 3 can be effectively used without being covered by the ropes 7 and 8.

また、上記フック11、12(容易着脱部)を、上記安全帯2/副帯3から外すときの操作位置、つまり開閉部18、18はどこにも隠れず、フック11、12の下方に常に露出しており、開閉部18、18の作動は上記開閉部25、25のように妨害されることもない。これにより、フック11、12は右側連結体41または左側連結体42から外し易くなり、作業効率が向上する。 Further, the operation position when the hooks 11 and 12 (easy attachment / detachment portion) are removed from the safety belt 2 / sub-belt 3, that is, the opening / closing portions 18 and 18 are not hidden anywhere and are always exposed below the hooks 11 and 12. Therefore, the operation of the opening / closing portions 18 and 18 is not hindered as in the opening / closing portions 25 and 25. As a result, the hooks 11 and 12 can be easily removed from the right side connecting body 41 or the left side connecting body 42, and the work efficiency is improved.

この外し易いというのは、上記伸縮調節器9、10のフック16、17と右側連結体41または左側連結体42との係合に比べてという意味であり、フック11、12が右側連結体41または左側連結体42から不用意に外れるという意味ではなく、安全性は保たれる。 This easy removal means that the hooks 16 and 17 of the expansion / contraction adjusters 9 and 10 are compared with the engagement between the right side connecting body 41 or the left side connecting body 42, and the hooks 11 and 12 are the right side connecting body 41. Or, it does not mean that it is inadvertently disconnected from the left side connecting body 42, and safety is maintained.

また、2本のロープ7、8は、安全帯2/副帯3上の作業する人の身体の中心線に対しほぼ左右対称の位置に係止されるので、後述するように、配電柱21上の障害物23をかわして昇降する場合に、ロープ7、8のフック11、12を一旦外して、再び、安全帯2/副帯3の右側連結体41または左側連結体42に係止する際に、着脱すべき落下防止ロープの順番を間違えことがなくなる。 Further, since the two ropes 7 and 8 are locked at positions substantially symmetrical with respect to the center line of the worker's body on the safety belt 2 / sub-belt 3, the power distribution column 21 will be described later. When moving up and down by avoiding the above obstacle 23, the hooks 11 and 12 of the ropes 7 and 8 are temporarily removed, and the ropes 2 / sub-band 3 are locked again to the right side connecting body 41 or the left side connecting body 42. At that time, the order of the fall prevention ropes to be attached and detached will not be mistaken.

ロープ7、8は、丈夫なナイロン製で、三本のストランドで構成された三つ打ち構造となっており、内部に芯を備えている。長さは、最大で3メートルほどである。上述したように、ロープ7、8のそれぞれの一端にはフック11、12(容易着脱部)が設けられ、他端には、伸縮調節器9、10を介してフック16、17(困難着脱部)が設けられている。 The ropes 7 and 8 are made of durable nylon and have a three-strand structure composed of three strands, and have a core inside. The maximum length is about 3 meters. As described above, hooks 11 and 12 (easy attachment / detachment portions) are provided at one end of each of the ropes 7 and 8, and hooks 16 and 17 (difficult attachment / detachment portions) are provided at the other ends via expansion / contraction adjusters 9 and 10. ) Is provided.

つまり、ロープ7、8は、柱状の構造物を周回し、両端が上記安全帯2/副帯3の異なる位置に着脱自在に係止される。図4に示すように、安全帯2/副帯3の作業者Mの背中側には、作業に必要な工具等を収納する収納部15を備えていてもよい。 That is, the ropes 7 and 8 orbit the columnar structure, and both ends are detachably locked at different positions of the safety belt 2 / sub-belt 3. As shown in FIG. 4, a storage unit 15 for storing tools and the like necessary for work may be provided on the back side of the worker M of the safety belt 2 / sub-band 3.

(6)安全装置の使用状態
図5、図6は、本発明による安全装置1の使用状態を示す。以下に、図5、図6を参照して、本発明の安全装置1の具体的な使用状態を説明する。作業する人Mは、副帯3を内側にして安全帯2/副帯3を腰部に周回し、バックル14で腰部から離脱しないようにしっかりと固定する。そして、作業者Mの左側のフック16から延びるロープ7を左側から時計回りに配電柱21を周回させ/巻き付け、伸縮調節器9でロープ7の長さを調節しながら、ロープ7の一端に設けられたフック11を安全帯2/副帯3の右側の右側連結体41に係合する。
(6) Usage state of the safety device FIGS. 5 and 6 show the usage state of the safety device 1 according to the present invention. Hereinafter, a specific usage state of the safety device 1 of the present invention will be described with reference to FIGS. 5 and 6. The worker M circulates the safety belt 2 / sub-belt 3 around the lumbar region with the sub-belt 3 inside, and firmly fixes the safety belt 2 / sub-belt 3 with the buckle 14 so as not to separate from the lumbar region. Then, the rope 7 extending from the hook 16 on the left side of the worker M is circulated / wound around the power distribution pole 21 clockwise from the left side, and is provided at one end of the rope 7 while adjusting the length of the rope 7 with the expansion / contraction adjuster 9. The hook 11 is engaged with the right side connecting body 41 on the right side of the safety belt 2 / sub-band 3.

つぎに、作業者Mの右側の右側連結体41に係合されるフック17(困難着脱部)から延びるロープ8は、配電柱21を周回させずに、他端に設けられたフック12を同じ右側連結体41に係合しておき使わない。ロープ7、8先端のフック11、12を一時的に外したときに、外したフック11、12を垂下した状態のままにしておくと、作業及び昇降の際に邪魔になり、ロープ7、8先端が作業者Mの身体の一部または配電柱21に絡まることがある。しかし、使わないロープ7、8のフック11、12を、配電柱21を周回しないで右側連結体41(左側連結体42)に係合しておけば、これを防ぐことができる。 Next, the rope 8 extending from the hook 17 (difficult attachment / detachment portion) engaged with the right side connecting body 41 on the right side of the worker M is the same as the hook 12 provided at the other end without rotating the power distribution pole 21. It is not used because it is engaged with the right side connecting body 41. When the hooks 11 and 12 at the tips of the ropes 7 and 8 are temporarily removed, if the removed hooks 11 and 12 are left in a hanging state, they will be an obstacle during work and ascending and descending, and the ropes 7 and 8 will be disturbed. The tip may be entangled with a part of the worker M's body or the distribution pole 21. However, this can be prevented by engaging the hooks 11 and 12 of the unused ropes 7 and 8 with the right side connecting body 41 (left side connecting body 42) without orbiting the power distribution pole 21.

上記状態で、作業者Mは、ステップボルト22…を手で掴み、あるいは足を順にかけながら、ロープ7のみを配電柱に周回させたまま、配電柱21を昇っていく。作業者Mが降柱する場合にも、同様にロープ7のみを配電柱に周回させたまま降柱する。このとき、ロープ8は両端のフック12、17を右側連結体41に係合させ垂下させて使わない状態となる。この使わないロープ8は、作業者Mの前には無く後ろ側に位置し、作業者Mの作業や昇降の邪魔にならない。このとき、ロープ7は配電柱21に周回させたままで安全である。 In the above state, the worker M climbs up the distribution pole 21 while grasping the step bolts 22 ... By hand or hanging his legs in order while circling only the rope 7 around the distribution pole. Similarly, when the worker M descends the pole, only the rope 7 is circulated around the distribution pole and the pole is descended. At this time, the rope 8 is in a state where the hooks 12 and 17 at both ends are engaged with the right side connecting body 41 and hung down so as not to be used. The unused rope 8 is located behind the worker M, not in front of it, and does not interfere with the work of the worker M or ascending / descending. At this time, the rope 7 is safe while being circulated around the power distribution pole 21.

また、図6は、作業者Mが障害物23を通過して昇柱する際の使用状態を示す。障害物23は配電柱21の外に突出して昇降の障害になるものである。作業者Mが、配電柱21上の障害物23のところまで昇った時点で、使わなかったロープ8のフック12を右側の右側連結体41からはずし、ロープ8を障害物23より上方で配電柱21を周回させ/巻き付け、フック12を左側連結体42に係止する。この場合、左側連結体42を目で確実に確認できるので、フック12の架け間違えがない。これは、左右逆の場合の、ロープ7のフック11を右側連結体41に係止する場合でも同じである。 Further, FIG. 6 shows a usage state when the worker M passes through the obstacle 23 and ascends a pillar. The obstacle 23 projects out of the distribution pole 21 and becomes an obstacle to ascending and descending. When the worker M climbs up to the obstacle 23 on the utility pole 21, the hook 12 of the unused rope 8 is removed from the right side connecting body 41 on the right side, and the rope 8 is removed from the power distribution pole above the obstacle 23. The 21 is rotated / wound, and the hook 12 is locked to the left side connecting body 42. In this case, since the left side connecting body 42 can be confirmed with the eyes, there is no mistake in hooking the hook 12. This is the same even when the hook 11 of the rope 7 is locked to the right side connecting body 41 in the case where the left and right sides are reversed.

次に、下側のロープ7先端のフック11(容易着脱部)を、安全帯2/副帯3に設けられた右側連結体41から外して左に回し、ロープ7の配電柱21の周回を解除する。そして、フック11を左側の左側連結体42に係合させてロープ7を垂下させて使わない、あるいは収納部15に収納しておき、配電柱21のステップボルト22…を上る。つまり、ロープ8一本を配電柱21に周回させた状態で昇柱する。このとき、右側連結体41及び左側連結体42は、作業者Mの左右逆の位置に設けられているため、フック11、12の係止位置を間違えることはない。 Next, the hook 11 (easy attachment / detachment portion) at the tip of the lower rope 7 is removed from the right side connecting body 41 provided in the safety belt 2 / sub-band 3 and turned counterclockwise to circulate the power distribution pole 21 of the rope 7. To release. Then, the hook 11 is engaged with the left side connecting body 42 on the left side to hang the rope 7 and is not used, or the rope 7 is stored in the storage portion 15 and climbs the step bolt 22 ... Of the power distribution pole 21. That is, the rope 8 is raised around the power distribution pole 21. At this time, since the right side connecting body 41 and the left side connecting body 42 are provided at positions opposite to each other on the left and right sides of the worker M, the locking positions of the hooks 11 and 12 are not mistaken.

以上のようにすれば、障害物23を超えて、配電柱21を上る場合にも、2本のロープ7、8の係止位置を取り違えることないため、安全に障害物23を回避して越えられる。 By doing so, even when climbing the distribution pole 21 beyond the obstacle 23, the locking positions of the two ropes 7 and 8 are not mistaken, so that the obstacle 23 can be safely avoided and crossed. Be done.

この場合、2本のロープ7、8とも、配電柱21上の係止部24などに係止させることなく、配電柱21を周回させて、障害物23を回避して越えられる。このため、ロープ7、8が、作業者Mの前に垂直方向に張られることがないため、作業の邪魔にならないし、昇降の邪魔にもならない。さらに、配電柱21上の障害物23をかわすためロープをかけかえるときも、一本のロープは配電柱21に周回された状態であるため、作業者Mが配電柱21にしがみつく必要がなく、両手が自由になって作業効率が向上し、安全で素早くロープのかけかえができる。 In this case, both of the two ropes 7 and 8 can be circulated around the distribution pole 21 without being locked to the locking portion 24 or the like on the distribution pole 21, and can be overcome by avoiding the obstacle 23. Therefore, since the ropes 7 and 8 are not stretched in the vertical direction in front of the worker M, they do not interfere with the work and do not interfere with the ascent and descent. Further, even when the rope is changed to avoid the obstacle 23 on the utility pole 21, since one rope is in a state of being circulated around the utility pole 21, the worker M does not have to cling to the utility pole 21. Both hands are freed to improve work efficiency, and the rope can be changed safely and quickly.

なお、場合によって、ロープ7、8のフック11、12を係止部24に係止させてもよい。この場合、ロープ8を配電柱21に周回させる前、ロープ8を配電柱21に周回させた後に、ロープ7を緩めた時に、ロープ7を外す前、またはロープ7を外した後に、ロープ8のフック12を係止部24に係止させてもよい。 In some cases, the hooks 11 and 12 of the ropes 7 and 8 may be locked to the locking portion 24. In this case, before the rope 8 is circulated around the distribution pole 21, after the rope 8 is circulated around the distribution pole 21, when the rope 7 is loosened, before the rope 7 is removed, or after the rope 7 is removed, the rope 8 The hook 12 may be locked to the locking portion 24.

さらに通常の昇降のときでも、または配電柱21での作業のときに、垂下させて使っていないロープ8のフック12を係止部24に係止することもできる。これにより、より安全となる。この場合、作業をしやすくするため、両方のロープ7の周回も解除することもできる。 Further, it is also possible to lock the hook 12 of the rope 8 which is not used by hanging down to the locking portion 24 even during normal ascending / descending or when working on the utility pole 21. This makes it safer. In this case, in order to facilitate the work, the laps of both ropes 7 can be canceled.

なお、障害物23を越えるとき、使っていないロープ8のフック12を係止部24に係止し、周回しているロープ7の周回を解除して、障害物23を乗り越えてロープ7を周回し直すことも可能ではある。しかし、これでは、作業者Mは、係止部24に係止される1本のロープ8だけで吊り下がっているので、体を安定させるため、片手または両手で配電柱21をつかんでいなくてはならず、両手が自由にならない。 When crossing the obstacle 23, the hook 12 of the unused rope 8 is locked to the locking portion 24, the lap of the orbiting rope 7 is released, and the rope 7 is circulated over the obstacle 23. It is also possible to redo. However, in this case, since the worker M is suspended only by one rope 8 locked to the locking portion 24, he / she does not hold the power pole 21 with one or both hands in order to stabilize his / her body. Must not be free of both hands.

これに対して、上記のようにロープ7、8を架け替えすれば、両手が自由になり、作業効率が向上し、より安全になる。また、係止部24を使うような場合には、常に係止部24があるとは限らず不便であるし、係止部24と間違えて、ステップボルト22にフック11、12を係止してしまうかもしれない。ロープ7、8を配電柱21に周回させて架け替えすれば、このような過誤はない。 On the other hand, if the ropes 7 and 8 are replaced as described above, both hands are freed, the work efficiency is improved, and the work becomes safer. Further, when the locking portion 24 is used, the locking portion 24 is not always present, which is inconvenient, and the hooks 11 and 12 are locked to the step bolt 22 by mistake for the locking portion 24. It may end up. If the ropes 7 and 8 are circulated around the distribution pole 21 and replaced, there is no such error.

障害物23をかわして配電柱21を降りる場合も、フック11、12(容易着脱部)のうち右側連結体41または左側連結体42に係合されている方のフックを外し、障害物23より下方で配電柱21を周回して、安全帯/副帯3の右側連結体41または左側連結体42に係止すれば、同様に、安全に降柱することができる。以上の障害物23の回避は、ロープ7と8との上下関係が入れ替わって、障害物23の下にロープ8があり、障害物23の上にロープ7を配置する場合でも同様に可能である。 When getting off the distribution pole 21 by avoiding the obstacle 23, remove the hook of the hooks 11 and 12 (easy attachment / detachment part) that is engaged with the right side connecting body 41 or the left side connecting body 42, and remove the hook from the obstacle 23. Similarly, if the power distribution pole 21 is circulated below and locked to the right side connecting body 41 or the left side connecting body 42 of the safety belt / sub-band 3, the pole can be safely lowered. The above avoidance of the obstacle 23 is similarly possible even when the vertical relationship between the ropes 7 and 8 is exchanged, the rope 8 is under the obstacle 23, and the rope 7 is arranged on the obstacle 23. ..

上記障害物23を越えるとき、上下のロープ7、8のフック11、12(容易着脱部)が左右逆になるため、2本のロープ7、8を左右で区別/右手と左手とで区別できる。このように左右で区別できるため、障害物23を越えるため配電柱21にいったん周回させたロープを再び誤って外してしまうことがなく、両方のロープを同時に装着体から外してしまうこともなくなる。 When the obstacle 23 is crossed, the hooks 11 and 12 (easy attachment / detachment part) of the upper and lower ropes 7 and 8 are reversed left and right, so that the two ropes 7 and 8 can be distinguished left and right / right hand and left hand. .. Since the left and right can be distinguished in this way, the rope once circulated around the power distribution pole 21 will not be accidentally removed again because the obstacle 23 is crossed, and both ropes will not be removed from the wearing body at the same time.

上記障害物23の断面の大きさは配電柱21を周回するロープ7、8の周回面積より小さい、または障害物23の配電柱21からの延びる長さは、周回するロープ7、8の配電柱21からの最大の離間長さより小さい。しかし、障害物23の大きさはこれらの逆の大きいものでもよい。 The size of the cross section of the obstacle 23 is smaller than the orbital area of the ropes 7 and 8 orbiting the distribution pole 21, or the length extending from the distribution pole 21 of the obstacle 23 is the distribution pole of the orbiting ropes 7 and 8. It is smaller than the maximum separation length from 21. However, the size of the obstacle 23 may be the opposite of these.

このような小さい障害物23を越えるときでも、2本のロープ7、8の周回の架け替えが行われてもよい。このような小さい障害物23を越えるときには、ロープ7、8の周回の架け替えが行われず、周回しているロープ7、8をそのまま障害物23を乗り越えてさせてもよい。このような架け替えを行わない場合、乗り越えるロープ以外のロープを配電柱21に周回させてもよいし、周回させなくてもよい。 Even when crossing such a small obstacle 23, the laps of the two ropes 7 and 8 may be replaced. When crossing such a small obstacle 23, the laps of the ropes 7 and 8 are not replaced, and the lapped ropes 7 and 8 may be allowed to pass over the obstacle 23 as they are. When such replacement is not performed, a rope other than the rope to be overcome may or may not be circulated around the utility pole 21.
