Description

この考案は、送電線の張替等に使用する吊り金車等の金車の扉のロック機構に関するものである。 The present invention relates to a lock mechanism for a door of a gold wheel such as a hanging wheel used for replacement of a transmission line.

前記金車は扉を有しており、当該扉を開閉することにより金車内のローラに電線やワイヤを掛けたり外したりする。そして、前記扉を閉めた状態でロックすることにより、作業中に扉がむやみに開かないようになっている。 The gold wheel has a door, and by opening and closing the door, an electric wire or a wire is hung or removed from a roller in the gold wheel. And by locking in the state which closed the said door, a door is prevented from opening unnecessarily during work.

そして、従来の前記扉のロック機構は、図９〜１２に示す様に、金車のフレーム１の開口部４に扉５が設けられ、当該扉５は一端をヒンジ６により回転自在に支持され、他端（自由端）の透孔８に前記フレーム１の開口部４端縁から突出する突起７を嵌めて係止している。そして、当該扉５の開閉により電線等の出し入れができるようになっている。 As shown in FIGS. 9 to 12, the conventional door lock mechanism is provided with a door 5 at the opening 4 of the frame 1 of the gold wheel, and one end of the door 5 is rotatably supported by a hinge 6. The projection 7 protruding from the edge of the opening 4 of the frame 1 is fitted and locked in the through hole 8 at the other end (free end). And the electric wire etc. can be taken in and out by opening and closing the said door 5. FIG.

前記金車の扉には係止に加えてロック機構が設けられている。当該ロック機構は、図９及び１０に示す様に、略逆Ｕ字型のピン２１の基部を扉５に設けたピン固定部２２に固定し、前記ピン２１の中腹部は、当該扉５の透孔８を貫通して扉５の外面に突出した前記突起７の傘部７ｂの下の軸部７ａを両側から挟持し、その先端を、扉５の外表面に設けられたねじ式つまみ２３の下で挟んでいる。 The door of the gold wheel is provided with a lock mechanism in addition to locking. As shown in FIGS. 9 and 10, the lock mechanism fixes the base portion of the substantially inverted U-shaped pin 21 to the pin fixing portion 22 provided on the door 5, and the middle portion of the pin 21 is connected to the door 5. A screw-type knob 23 provided on the outer surface of the door 5 is sandwiched from both sides of the shaft portion 7a below the umbrella portion 7b of the projection 7 that penetrates the through hole 8 and protrudes to the outer surface of the door 5. Is sandwiched under.

また、ネジ式つまみ２３は、図１１に示す様に、軸基部２３ａとその先に軸部２３ｂを有しており、前記軸基部２３ａが板状に形成され、ネジ式つまみ２３を９０度回転させ、軸基部２３ａの幅の大きい両端部がピン２１に当たると、ピン２１は開かれ、一方、軸基部２３ａの小幅な両側にピン２１が当たるとピン２１はすぼまるように形成せれている。 As shown in FIG. 11, the screw-type knob 23 has a shaft base portion 23a and a shaft portion 23b at the tip thereof. The shaft base portion 23a is formed in a plate shape, and the screw-type knob 23 is rotated by 90 degrees. When the both ends of the shaft base portion 23a hit the pin 21, the pin 21 is opened. On the other hand, when the pin 21 hits both sides of the shaft base portion 23a, the pin 21 is formed so as to sag. .

そして、図１０に示す様に、ネジ式つまみ２３の軸基部２３ａの小幅な両側に前記ピン２１が当たった状態で、ピン２１はその２本の先端をネジ式つまみ１０に押圧されて固定され、ピン２１の２本の各中腹部は前記突起７の傘部７ｂ下の軸部７ａに嵌って突起７を挟持した状態でロックされている。 Then, as shown in FIG. 10, in the state where the pin 21 is in contact with both narrow sides of the shaft base portion 23a of the screw type knob 23, the two ends of the pin 21 are pressed and fixed by the screw type knob 10. The two middle abdominal portions of the pin 21 are locked in a state in which the projection 7 is sandwiched by fitting into the shaft portion 7a below the umbrella portion 7b of the projection 7.

当該ロックを解くには、ネジ式つまみ２３を９０度回転させると軸基部２３ａの大幅な両端部にピン２１が当たって大きく広がり、図１２に示す様に、２本のピン２１は前記突起７の傘部７ｂから外れ、前記ロックは解除される。これにより作業者は扉５を引っ張って容易に開けることが出来る。このロック機構は特許文献１の従来の技術の欄及び図６にも記載されている。 In order to release the lock, when the screw type knob 23 is rotated 90 degrees, the pins 21 hit the large both ends of the shaft base portion 23a so as to spread widely, and as shown in FIG. And the lock is released. Thus, the operator can easily open the door 5 by pulling it. This locking mechanism is also described in the prior art section of Patent Document 1 and FIG.

しかしながら、前記図９〜１２に示すものは、扉５を閉めた後、ネジ式つまみ２３を９０度回転させなければロックされないが、当該ネジ式つまみ２３の９０度の回転を忘れてしまう作業者が多い。また、ピン２１は２本のピンがバネで相互に近接する方向に力が働き、開ける場合は、当該バネの力に抗してピン２１を開くため、使用によりへたりが生じ、作業中にロックが解除されて扉５が開く恐れがあった。 However, those shown in FIGS. 9 to 12 are not locked unless the screw-type knob 23 is rotated 90 degrees after the door 5 is closed, but the operator forgets to rotate the screw-type knob 23 by 90 degrees. There are many. In addition, the pin 21 has a force acting in the direction in which the two pins are close to each other by a spring. When the pin 21 is opened, the pin 21 is opened against the force of the spring. There was a risk of the door 5 being opened after being unlocked.

そこで、この考案はこの様にロックのし忘れや、部材のへたり等が中々生じない、ロックが容易かつ確実で堅牢な構成の金車扉のロック機構を提供することを目的としたものである。 Therefore, the present invention is intended to provide a lock mechanism for a gold wheel door having an easy, reliable and robust configuration that does not cause forgetting to lock or sag of members. is there.

（実施の形態例１）
この考案の実施の形態例１の金車の扉のロック機構を図１〜８に基づいて説明する。 (Embodiment 1)
A lock mechanism for a door of a gold wheel according to a first embodiment of the present invention will be described with reference to FIGS.

金車Ａは、縦長のフレーム１内の上下に回転自在なローラ２、３を有しており、前記フレーム１の一側上部に開口部４を有し、当該開口部４を塞ぐ扉５を有している。当該扉５はその下端のヒンジ６により、前記開口部４を開閉自在となっている。また、前記フレーム１の開口部４の開口端縁から突起７が突設されており（図３参照）、扉５の自由端側部に設けた透孔８に挿通することにより扉５が閉まるようになっている。 The gold wheel A has rollers 2 and 3 that are rotatable up and down in a vertically long frame 1, has an opening 4 on one side upper part of the frame 1, and has a door 5 that closes the opening 4. Have. The door 5 can be opened and closed by a hinge 6 at the lower end thereof. In addition, a projection 7 projects from the opening edge of the opening 4 of the frame 1 (see FIG. 3), and the door 5 is closed by being inserted into a through hole 8 provided on the free end side of the door 5. It is like that.

そして、扉５の自由端の外側面に、扉５の上下方向に摺動自在なスライド板９が設けられている。当該スライド板９は、図４に示す様に、上端部に長孔１０を有し、当該長孔１０に、扉５の外面から突出する突出軸１１が遊貫し、当該突出軸１１の先端に固定したナット１２に係止されている。また、前記スライド板９には、図４に示す様に、第１だるま穴１３が設けられている。 A slide plate 9 slidable in the vertical direction of the door 5 is provided on the outer surface of the free end of the door 5. As shown in FIG. 4, the slide plate 9 has a long hole 10 at its upper end, and a protruding shaft 11 protruding from the outer surface of the door 5 penetrates the long hole 10, and the tip of the protruding shaft 11 The nut 12 is fixed to the nut 12. Further, as shown in FIG. 4, the slide plate 9 is provided with a first saddle hole 13.

当該第１だるま穴１３は、前記突起７の軸部７ａが貫通できる小径穴１３ａと、前記突起７の傘部７ｂが貫通可能な大径穴１３ｂが連なって形成され、前記小径穴１３ａは上方に、前記大径穴１３ｂは下方に位置している。そして、前記スライド板９が上方にスライドすると前記透孔８と大径穴１３ｂが重なるようになっている。 The first saddle hole 13 is formed by connecting a small-diameter hole 13a through which the shaft portion 7a of the projection 7 can penetrate and a large-diameter hole 13b through which the umbrella portion 7b of the projection 7 can penetrate, and the small-diameter hole 13a extends upward. In addition, the large-diameter hole 13b is positioned below. When the slide plate 9 slides upward, the through hole 8 and the large diameter hole 13b overlap each other.

また、前記スライド板９の下端部には第２だるま穴１４が設けられ、当該第２だるま穴１４は前記第１だるま穴１３と逆方向になっており、上方に大径穴１４ａを有し、下方に小径穴１４ｂを有している。また、当該第２だるま穴１４には、扉４の外面に突設された支軸１５が挿通している。また、当該支軸１５を貫通した筒状のつまみ１６が支軸１５に設けられている。 Further, a second saddle hole 14 is provided at the lower end portion of the slide plate 9, and the second saddle hole 14 is in a direction opposite to that of the first saddle hole 13, and has a large-diameter hole 14a above. A small-diameter hole 14b is provided below. A support shaft 15 protruding from the outer surface of the door 4 is inserted through the second saddle hole 14. A cylindrical knob 16 that penetrates the support shaft 15 is provided on the support shaft 15.

当該つまみ１６の基部には小径端部１６ａが段部を設けて形成され、当該小径端部１６ａは前記第２だるま穴１４の大径穴１４ａに嵌合自在となっている。また、前記支軸１５の先端には頭部１５ａを有し、当該頭部１５ａとつまみ１６の中空内部端との間の支軸１５の外周にバネ１７が設けられ、当該バネ１７の力で常時つまみ１６はその小径端部１６ａが前記第２だるま穴１４の大径穴１４ａに嵌合するか、小径穴１４ｂの上面を押圧する。 A small-diameter end portion 16 a is formed at the base of the knob 16 with a stepped portion, and the small-diameter end portion 16 a can be freely fitted into the large-diameter hole 14 a of the second bowl hole 14. Further, a head 15 a is provided at the tip of the support shaft 15, and a spring 17 is provided on the outer periphery of the support shaft 15 between the head 15 a and the hollow inner end of the knob 16. The constant-sized knob 16 has a small-diameter end 16a fitted into the large-diameter hole 14a of the second saddle hole 14 or presses the upper surface of the small-diameter hole 14b.

また、前記スライド板９の下端下方の扉５に、扉５の色彩と異なる色彩の着色部１８を設けている。当該着色部１８はつまみ１６をバネ１７の力に抗して引っ張り、つまみ１６の小径端部１６ａを第２だるま穴１４の大径穴１４ａから外し、スライド板９を上方に引き上げ、ロックが解除された状態で、スライド板９の下端外方の着色部１８が露出し、当該着色部１８を視認できる。なお、図では前記着色部１８を盛り上げて記載しているが、これは着色部１８をシールで形成した場合であり、扉５に直接塗装して着色部１８を形成することもできる。 Further, a colored portion 18 having a color different from the color of the door 5 is provided on the door 5 below the lower end of the slide plate 9. The coloring portion 18 pulls the knob 16 against the force of the spring 17, removes the small-diameter end portion 16 a of the knob 16 from the large-diameter hole 14 a of the second boring hole 14, pulls the slide plate 9 upward, and releases the lock. In this state, the colored portion 18 outside the lower end of the slide plate 9 is exposed, and the colored portion 18 can be visually recognized. In addition, although the said colored part 18 is raised and described in the figure, this is a case where the colored part 18 is formed with a seal, and the colored part 18 can also be formed by painting directly on the door 5.

従って、作業者は当該着色部１８が見えている状態では当該扉５のロックが解除されていることが確認できる。一方、ロックがされている状態では着色部１８は視認できないため、着色部１８が見えない時は、ロックがかかっていることが確認できる。 Therefore, the operator can confirm that the door 5 is unlocked in a state where the colored portion 18 is visible. On the other hand, since the colored portion 18 cannot be visually recognized in the locked state, it can be confirmed that the colored portion 18 is locked when the colored portion 18 is not visible.

以上の構成により、前記突起７の軸部７ａが第１だるま穴１３の小径穴１３ａを貫通して傘部７ｂが小径穴１３ａの上面に係止された状態では前記つまみ１６の小径端部１６ａがバネ１７の力により前記第２だるま穴１４の大径部１４ａに嵌合されており、この状態ではスライド板９は動くことは不可能となり、これにより扉５はロックされる。従って、むやみに前記ロックが解除されることはない。 With the above configuration, the small diameter end portion 16a of the knob 16 is obtained when the shaft portion 7a of the projection 7 passes through the small diameter hole 13a of the first barrel hole 13 and the umbrella portion 7b is locked to the upper surface of the small diameter hole 13a. Is fitted to the large diameter portion 14a of the second saddle hole 14 by the force of the spring 17, and in this state, the slide plate 9 cannot move and the door 5 is locked. Therefore, the lock is not released unnecessarily.

また、前記ロックを解除するには、前記つまみ１６をバネ１７の力に抗してつまみ上げ、この状態でスライド板９を上げる。これによりつまみ１６の小径端部１６ａが第２だるま穴１４の小径穴１４ｂの上面に載って係止され、これと同時に突起７の傘部７ｂが第１だるま穴１３の大径穴１３ｂに位置して、扉のロックが解除される。そして、この状態で扉５を手前に倒すと、突起７の傘部７ｂが扉５の透孔８を通り、扉５は開く。 To release the lock, the knob 16 is lifted against the force of the spring 17, and the slide plate 9 is raised in this state. As a result, the small-diameter end portion 16a of the knob 16 is placed and locked on the upper surface of the small-diameter hole 14b of the second boring hole 14, and at the same time, the umbrella portion 7b of the projection 7 is positioned in the large-diameter hole 13b of the first boring hole 13. Then, the door is unlocked. When the door 5 is tilted forward in this state, the umbrella portion 7b of the protrusion 7 passes through the through hole 8 of the door 5, and the door 5 opens.

なお、上記実施の形態例１では、スライド板９のスライド方向、スライド幅を長孔１０及び突出軸１１等により規制しているが、これに代えて、例えば、スライド板９のスライド方向、幅を規制する四辺形の枠体を扉に設け、当該枠体内でスライド板９を摺動させる構成にすることもできる。 In the first embodiment, the slide direction and the slide width of the slide plate 9 are regulated by the long hole 10 and the protruding shaft 11, but instead, for example, the slide direction and width of the slide plate 9 are regulated. It is also possible to provide a structure in which a quadrilateral frame body that regulates the above is provided on the door and the slide plate 9 is slid within the frame body.
